The example uses the file, books.xml, as input. The long form of an assembly name consists of its simple name (such as "System" for the System.dll assembly) along with its version, culture, public key token, and optionally its processor architecture. How should the Load method handle loading rows that have the same primary key as existing rows? This function is supported in the following shader models. Supplying a partial assembly name for assemblyRef is not recommended. If the registry key name contains a space, enclose the key name in quotes. More info about Internet Explorer and Microsoft Edge. Load balancer supports both inbound and outbound scenarios. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Preserve changes and re-synchronize from the primary data source. For this code example to run, you must provide the fully qualified assembly name. In this scenario, the user wants to merge changes from one or more secondary data sources, and propagate those changes back to the primary data source. Call GetTemplateChild with the name that you defined on the element. Do not use an AssemblyName with only the CodeBase property set. This file is in format. C# public System.Reflection.Assembly Load (byte[] rawAssembly); Parameters rawAssembly Byte [] An array of type byte that is a COFF-based image containing an emitted assembly. More info about Internet Explorer and Microsoft Edge. You can use this event to perform tasks such as allocating resources used by the form. WebTo load the correct assembly, it's recommended to call the Load method by passing the long form of the assembly name. This method provides the same functionality, but allows you to load multiple result sets from an IDataReader into multiple tables within a DataSet. The object that describes the assembly to be loaded. If you select the Upsert option, it is assumed that the data is coming from one of a secondary data source, such as data provided by a middle-tier component, perhaps altered by a user. The tables parameter allows you to specify an array of table names, indicating the order of the tables corresponding to each result set loaded from the reader. More info about Internet Explorer and Microsoft Edge, Load(IDataReader, LoadOption, DataTable[]), Load(IDataReader, LoadOption, FillErrorEventHandler, DataTable[]). Evidence of the calling assembly and evidence of the COFF image are ignored. The tables parameter allows you to specify an array of DataTable instances, indicating the order of the tables corresponding to each result set loaded from the reader. This file must be created in advance by using the For more information about the use of evidence with overloads of the Load method that take byte arrays, see the Load(Byte[], Byte[], Evidence) method overload. Load columns as: Individual columns like Size and CurrentPrices in the HousingData class. In this scenario, the user wants to merge changes from one or more secondary data sources, and propagate those changes back to the primary data source. Here are two examples of using Load. The DataSet isn't responsible for tracking changes in order to allow synchronization with the secondary data source. Should it modify current values, original values, or both? Once the data has been loaded, the example displays the contents of all its tables in the Console window. C# public virtual void Load (string filename); Parameters filename String URL for the file containing the XML document to load. In this case, the method doesn't allow you to indicate the load option, and uses the default, PreserveChanges. An IDataReader that provides one or more result sets. If you call the Load method more than once on the same assembly but with a different evidence specified, the common language runtime does not throw a FileLoadException because the equality and integrity of the different evidence specifications cannot be determined. Required for multi-sample textures. Notifies the server control to perform any processing steps that are set to occur on each page request. Call GetTemplateChild with the name that you defined on the element. An Azure load balancer is a Layer-4 (TCP, UDP) load balancer that provides high availability by distributing incoming traffic among healthy VMs. Methods which use evidence to sandbox are obsolete and will be removed in a future release of the .NET Framework. assemblyRef specifies a remote assembly, but the ability to execute code in remote assemblies is disabled. This applies to the .NET Framework version 1.1 Service Pack 1 (SP1) and subsequent releases. Developers, testers, and quality assurance (QA) engineers can use it to optimize application performance, scalability, or capacity. Not supported for other textures. Reflecting on C++ executable files might throw a BadImageFormatException. The first is taken from a Windows Forms data binding application where Load is used to query for entities before binding to the local collection, as described in Local Data: The second example shows using Load to load a filtered collection of related entities, as described in Loading Related Entities: More info about Internet Explorer and Microsoft Edge. This action value varies, depending on the state of the row before the load operation. This method allows you to specify a load option parameter, indicating how rows already in a DataTable combine with rows being loaded. Some information relates to prerelease product that may be substantially modified before its released. The following example instantiates an AssemblyName object and uses it to load the sysglobal.dll assembly. There is a set of screens provided and all are in .xaml extensions. The example then focuses on data issues, including handling the various loading options. To load an extension DLL, you can do one of the following: Use the .load or .loadby command. However, the recommended way to specify an assembly name is to create an AssemblyName object and pass it to an appropriate overload of the Load method. Let me explain it again. Use the Show method to make the object visible. The load operation will fail with an InvalidOperationException if any of the source data columns in the incoming reader are computed columns. Developers, testers, and quality assurance (QA) engineers can use it to optimize application performance, scalability, or capacity. The evidence that first succeeds is the evidence that is used. The following example illustrates the use of a long name to load the System.dll assembly for the .NET Framework 4: Note: In .NET for Windows Store apps or the Portable Class Library, catch the base class exception, IOException, instead. The name resolution scheme for this method is the same as that followed by the Fill method of the DbDataAdapter class. Starting with .NET Framework 4, because execution of code in remote assemblies is disabled by default, a FileLoadException is also thrown if assemblyRef specifies a remote assembly. The Load method can be used in several common scenarios, all centered around getting data from a specified data source and adding it to the current data container (in this case, a DataSet). Let me explain it again. The evidence that first succeeds is the evidence that is used. Loads an Assembly into this application domain. A DataSet synchronizes or updates with a single primary data source. Loads the assembly with a common object file format (COFF)-based image containing an emitted assembly, optionally including symbols for the assembly. The following example creates a new DataSet, adds two DataTable instances to the DataSet, and then fills the DataSet using the Load method, retrieving data from a DataTableReader that contains two result sets. More info about Internet Explorer and Microsoft Edge, Load(Byte[], Byte[], SecurityContextSource), http://go.microsoft.com/fwlink/?LinkID=155570. If your application needs to know which encoding is used to read the stream, consider using an XmlTextReader object to read the stream, and then use the XmlTextReader.Encoding property to determine the encoding. WebThe Load method provides a technique for filling a single DataTable with data, retrieved from an IDataReader instance. Valid root keys for the local computer are: HKLM, HKCU, HKCR, HKU, and HKCC. In terms of event operations, the RowChanging event occurs before each row is changed, and the RowChanged event occurs after each row has been changed. Execute an extension by issuing the full !DLLName.ExtensionCommand syntax. When you use a Load method with an Evidence parameter, pieces of evidence are merged. The following table displays behavior for the Load method. typeX denotes that there are four possible types: int, int2, int3 or int4. Instead, the assembly is loaded using load-from rules. These scenarios describe standard usage for a DataTable, describing its update and merge behavior. Some information relates to prerelease product that may be substantially modified before its released. Key scenarios that you can accomplish using Azure Standard The long form of an assembly name consists of its simple name (such as "System" for the System.dll assembly) along with its version, culture, public key token, and optionally its processor architecture. A load balancer health probe monitors a given port on each VM and only distributes traffic to an operational VM. Loads the assembly with a common object file format (COFF)-based image containing an emitted assembly. WebLoad (String) Loads the XML document from the specified URL. WebThis occurs because the form values have already been loaded. For more information, see Reading XML Data using XPathDocument and XmlDocument. If both the AssemblyName.Name property and the AssemblyName.CodeBase property are set, the first attempt to load the assembly uses the display name (including version, culture, and so on, as returned by the Assembly.FullName property). A byte array that contains the raw bytes representing the symbols for the assembly. Subsequent clicking on UserForm2 reveals UserForm1. The techniques shown in this topic apply equally to models created with Code First and the EF Designer. Loading Elements There are several different ways to load the elements: Use an x:Bind expression to specify the load state. See Row States and Row Versions for more information. (A partial name omits one or more of culture, version, or public key token. The service simulates traffic for your applications, regardless of where they're hosted. Parameters Object It corresponds to the assembly's FullName property. These values may be equivalent, or may be different if the data in the row has been changed since filling the DataTable. The schemas are compatible, but the loaded result set schema contains columns that do not exist in the, The schemas are compatible, but the loaded result set schema contains fewer columns than does the, If a missing column has a default value defined or the column's data type is nullable, the, The schemas are compatible, but the loaded result set schema contains columns that don't exist in the, Original version, if it exists, otherwise Current version, Current version, if it exists, otherwise Original version. An array of type byte that is a COFF-based image containing an emitted assembly. This method should be used only to load an assembly into the current application domain. (The overload that doesn't allow you to specify the behavior uses the default load option.) Zone, Url and Site are inherited from the calling assembly, and Hash and StrongName are taken from the COFF assembly. Finally, the example displays the contents of the tables in the console window. With Azure Load Balancer, you can scale your applications and create highly available services. WebLoad (String) Loads the XML document from the specified URL. Preserve changes and re-synchronize from the primary data source. This applies to the .NET Framework version 1.1 Service Pack 1 (SP1) and subsequent releases. SampleIndex must always be specified first with multi-sample textures. If the reader is in the initial state (ReadState =ReadState.Initial), Load consumes the entire contents of the reader and builds the DOM from what it finds. To load the correct assembly, it's recommended to call the Load method by passing the long form of the assembly name. Returns XDocument An XDocument object that reads the data that is contained in the stream. These scenarios describe standard usage for a DataSet, describing its update and merge behavior. Azure Load Testing Preview is a fully managed load-testing service that enables you to generate high-scale load. Each of these tables must be a member of the DataTableCollection contained by this DataSet. Load columns as: Individual columns like Size and CurrentPrices in the HousingData class. Load (DirectX HLSL Texture Object) Article 04/28/2022 2 minutes to read 6 contributors Feedback In this article Parameters Return Value Minimum Shader Model Example Related topics Reads texel data without any filtering or sampling. The return type matches the type in the Object declaration. The URL can be either a local file or an HTTP URL (a Web address). Microsoft makes no warranties, express or implied, with respect to the information provided here. WebLoad (String) Loads the XML document from the specified URL. To determine which version of the primary key field to use for comparing the current row with an incoming row, the Load method uses the original version of the primary key value within a row, if it exists. There is a set of screens provided and all are in .xaml extensions. The offset type is dependent on the texture-object type, and needs to be static. Each cell in this table describes the current and original value for a field within a row, along with the DataRowState for the value after the Load method has completed. Each cell in this table describes the current and original value for a field within a row, along with the DataRowState for the value after the Load method has completed. Have questions or feedback about Office VBA or this documentation? The following table describes the three load options provided by the LoadOption enumeration. A FillErrorEventHandler delegate to call when an error occurs while loading data. To load an extension DLL, you can do one of the following: Use the .load or .loadby command. In this method call, the specified LoadOption parameter influences the processing of the incoming data. The assembly is loaded into the application domain of the caller using the specified source for the security context. To enable execution of code loaded from remote locations, you can use the configuration element. Occurs when the server control is loaded into the Page object. Load balancing aims to optimize resource use, maximize throughput, minimize response time, and avoid overloading any single resource. The stream containing the XML document to load. Updates the original version of the row with the value of the incoming row. See AssemblyName.ProcessorArchitecture. The assembly is loaded into the application domain of the caller. assemblyRef is not a valid assembly. In the .NET Framework version 1.0 and in version 1.1 without SP1, when you use a Load method overload with a Byte[] parameter to load a COFF image, evidence is combined. Beginning with the .NET Framework 4, the trust level of an assembly that is loaded by using this method is the same as the trust level of the application domain. The raw bytes representing the symbols for the assembly are also loaded. A good example of this is loading entities for data binding as described in Local Data. Valid root keys for the local computer are: HKLM, HKCU, HKCR, HKU, and HKCC. WebThe Load method can be used in several common scenarios, all centered around getting data from a specified data source and adding it to the current data container (in this case, a DataTable ). Note that this method overload always creates a new Assembly object with its own mapping. Next steps. The output is displayed in the console window. This method is obsolete and will be removed in a future release of the .NET Framework. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. A value from the LoadOption enumeration that indicates how rows already in the DataTable instances within the DataSet will be combined with incoming rows that share the same primary key. Remarks Loads the Assembly with a common object file format (COFF) based image containing an emitted Assembly. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. The service simulates traffic for your applications, regardless of where they're hosted. It's important to note that all of the elements in the vector More info about Internet Explorer and Microsoft Edge, Load(IDataReader, LoadOption, FillErrorEventHandler). The display name of the assembly. Please use an overload of Load which does not take an Evidence parameter. You define a front-end IP configuration that contains one or more public Remarks When an object is loaded, it is placed in memory, but isn't visible. The assembly is loaded into the domain of the caller using the supplied evidence. The loadOption parameter allows you to specify how you want the imported data to interact with existing data, and can be any of the values from the LoadOption enumeration. Microsoft makes no warranties, express or implied, with respect to the information provided here. WebThe Load method provides a technique for filling a single DataTable with data, retrieved from an IDataReader instance. The file specified in filename was not found. Firstly, I want to load a Main Screen file from 'C:\MainScreen.xaml'. In this scenario, the user wants to initialize an empty DataSet with values from the primary data source. WebThe Load method can be used in several common scenarios, all centered around getting data from a specified data source and adding it to the current data container (in this case, a DataTable ). ; If you have a vector property, apply the VectorType attribute to the property in your data model. In each case, both events occur, and the action is the same for each. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. This operation is not supported on the current platform. A DataTable synchronizes or updates with a single primary data source. URL for the file containing the XML document to load. Evidence of the calling assembly and evidence of the COFF image is ignored. The specified path, file name, or both exceed the system-defined maximum length. C# public System.Reflection.Assembly Load (byte[] rawAssembly); Parameters rawAssembly Byte [] An array of type byte that is a COFF-based image containing an emitted assembly. Load object The object placeholder represents an object expression that evaluates to an object in the Applies To list. An array of type byte containing the raw bytes representing the symbols for the assembly. The following example demonstrates how to use the SetDesktopLocation, Load, Activated, and Activate members. Otherwise, the Load method uses the current version of the primary key field. Given these two hypothetical data sources, a user is likely to require one of the following behaviors: Initialize DataSet from a primary data source. If the existing row and the incoming row contain corresponding primary key values, the row is processed using its current row state value, otherwise it's treated as a new row. This has the following results. Please use an overload of Load which does not take an Evidence parameter. These scenarios describe standard usage for a DataTable, describing its update and merge behavior. Here are two examples of using Load. The loader does not continue probing for other assemblies that match the simple name. Microsoft makes no warranties, express or implied, with respect to the information provided here. If you call this method more than once on the same assembly but with a different evidence specified, the common language runtime does not throw a FileLoadException because the equality and integrity of the different evidence specifications cannot be determined. Until an object is visible, a user can't interact with it. Updates the original version of the row with the value of the incoming row. Incremental data feed from secondary data sources. Until an object is visible, a user can't interact with it. Next steps. See http://go.microsoft.com/fwlink/?LinkId=155570 for more information. This partial code example is from the Paint.fx file in the AdvancedParticles Sample. Before considering the behavior of the Load method in terms of data operations, consider that each row within a DataTable maintains both the current value and the original value for each column. securityEvidence is not null. This method is a Microsoft extension to the Document Object Model (DOM). The example then calls the Load method, displaying the data both before and after the load operation. The following example demonstrates several of the issues involved with calling the Load method. An Azure load balancer is a Layer-4 (TCP, UDP) load balancer that provides high availability by distributing incoming traffic among healthy VMs. An array of DataTable instances, from which the Load(IDataReader, LoadOption, FillErrorEventHandler, DataTable[]) method retrieves name and namespace information. Forms Assembly: System.Windows.Forms.dll Important Some information relates to prerelease product that may be substantially modified before its released. When you use a Load method overload with a Byte[] parameter to load a common object file format (COFF) image, evidence is inherited from the calling assembly. For information about how to obtain the fully qualified assembly name, see Assembly Names. For example, the following code loads MyAssembly into the new application domain ChildDomain and also into the application domain where the code executes: The assembly is loaded into both domains because Assembly does not derive from MarshalByRefObject, and therefore the return value of the Load method cannot be marshaled. An object that describes the assembly to load. Microsoft makes no warranties, express or implied, with respect to the information provided here. If the registry key name contains a space, enclose the key name in quotes. WebTo load the correct assembly, it's recommended to call the Load method by passing the long form of the assembly name. Version 2.0 or later of the common language runtime is currently loaded and rawAssembly was compiled with a later version. If the existing row and the incoming row contain corresponding primary key values, the row is processed using its current row state value, otherwise it's treated as a new row. Before considering the behavior of the Load method in terms of data operations, consider that each row within a DataTable maintains both the current value and the original value for each column. For overloads that take a string instead of an AssemblyName object, "MyAssembly, Version=1.0.0.0" is an example of a partial name and "MyAssembly, Version=1.0.0.0, Culture=neutral, PublicKeyToken=18ab3442da84b47" is an example of a full name.) In general, the PreserveChanges and OverwriteChanges options are intended for scenarios in which the user needs to synchronize the DataSet and its changes with the primary data source. For more information, see the Remarks section of the XmlReader reference page. The term load balancing refers to the distribution of workloads across multiple computing resources. In this typeX denotes that there are four possible types: int, int2, int3 or int4. Let me explain it again. If a remote computer is specified, valid root keys are: HKLM and HKU. The long form of an assembly name consists of its simple name (such as "System" for the System.dll assembly) along with its version, culture, public key token, and optionally its processor architecture. Loads the assembly with a common object file format (COFF)-based image containing an emitted assembly, optionally including symbols and evidence for the assembly. Here are two examples of using Load. Please use an overload of Load which does not take an Evidence parameter. If no matching table is found, a table is created using the name supplied in the array of table names, and the new table's schema is inferred from the result set. More info about Internet Explorer and Microsoft Edge, Introduction to the ASP.NET Page Life Cycle. C# Copy public static System.Xml.Linq.XDocument Load (System.IO.Stream stream); Parameters stream Stream The stream that contains the XML data. Specifies the name and path of the file to be loaded. Load balancer provides low latency and high throughput, and scales up to millions of flows for all TCP and UDP applications. Returns XDocument An XDocument object that reads the data that is contained in the stream. Fills a DataTable with values from a data source using the supplied IDataReader using an error-handling delegate. The PreserveWhitespace property determines whether or not insignificant white space, that is white space in element content, is preserved. WebLoad (String) Load (Byte [], Byte []) Overloads Load (Byte []) Loads the Assembly with a common object file format (COFF) based image containing an emitted Assembly. See the documentation for the Load method for more information on using this parameter. The final row (labeled "(Not present)") describes the behavior for incoming rows that don't match any existing row. This version of the Load method attempts to preserve the current values in each row, leaving the original value intact. If you need to use a XmlDocument object to work with XML, you can use the XmlTextReader object to create one. The first is taken from a Windows Forms data binding application where Load is used to The CodeBase property does not supply any elements of the assembly identity (such as name or version), so loading does not occur according to load-by-identity rules, as you would expect from the Load method. See FullName.

Writes saved subkeys and entries into a different subkey in the registry. Rather than trapping the error, this example uses a FillErrorEventHandler delegate to investigate and handle the error. The term load balancing refers to the distribution of workloads across multiple computing resources. A file that was found could not be loaded. Later the user intends to propagate changes back to the primary data source. For information that is common to all overloads of this method, see the Load(AssemblyName) method overload. Remarks The Load extension method works just like ToList except that it avoids the creation of the list altogether. typeX denotes that there are four possible types: int, int2, int3 or int4. [in] An optional offset applied to the texture coordinates before sampling. Until an object is visible, a user can't interact with it. Load balancer provides low latency and high throughput, and scales up to millions of flows for all TCP and UDP applications. These issues, and more, are controlled by the loadOption parameter. The example then adds tables to a DataSet and attempts to fill the tables with data from a DataTableReader. Loads the XML document from the specified TextReader. In this case, the document remains empty. The Load extension method works just like ToList except that it avoids the creation of the list altogether. If the current node and its siblings look like the following: Load throws an exception because a document cannot have two root level elements. A load balancer health probe monitors a given port on each VM and only distributes traffic to an operational VM. Here are two examples of using Load. Loads the assembly with a common object file format (COFF)-based image containing an emitted assembly, optionally including symbols and specifying the source for the security context. When working with the schema, the Load method may encounter conditions as described in the following table. These scenarios describe standard usage for a DataTable, describing its update and merge behavior. An assembly or module was loaded twice with two different evidences. The techniques shown in this topic apply equally to models created with Code First and the EF Designer. Fills a DataTable with values from a data source using the supplied IDataReader. When converting data, the Load method uses the same conversion rules as the Fill method. . When converting data, the Load method uses the same conversion rules as the DbDataAdapter.Fill method. See the documentation for the DataTableLoad method for more information on using this parameter. The Load method consumes the first result set from the loaded IDataReader, and after successful completion, sets the reader's position to the next result set, if any. Loads the XML document from the specified XmlReader. FileLoadException is thrown if assemblyString specifies the full assembly name, and the first assembly that matches the simple name has a different version, culture, or public key token. Applies to See also Introduction to the ASP.NET Page Life Cycle Recommended content UpdatePanel (System.Web.UI) LinkButton (System.Web.UI.WebControls) Web The long form of an assembly name consists of its simple name (such as "System" for the System.dll assembly) along with its version, culture, public key token, and optionally its processor architecture. All but one of the overloads for this method allows you to specify a load option parameter, indicating how rows already in a DataTable combine with rows being loaded. This is most likely caused by the C++ compiler stripping the relocation addresses or the .reloc section from your executable file. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. This action value depends on the state of the row before the load operation. If a remote computer is specified, valid root keys are: HKLM and HKU. Load (DirectX HLSL Texture Object) Article 04/28/2022 2 minutes to read 6 contributors Feedback In this article Parameters Return Value Minimum Shader Model Example Related topics Reads texel data without any filtering or sampling. The trust level of an assembly that is loaded by using this method is the same as the trust level of the calling assembly. You define a front-end IP configuration that contains one or more public In terms of event operations, the RowChanging event occurs before each row is changed, and the RowChanged event occurs after each row has been changed. The expression should return true to load and false to unload the element. The default namespace associated with DataSet, if any, is associated with each newly created DataTable. Microsoft makes no warranties, express or implied, with respect to the information provided here. Call FindName with the name that you defined on the element. Fills a DataSet with values from a data source using the supplied IDataReader, using an array of DataTable instances to supply the schema and namespace information. Developers, testers, and quality assurance (QA) engineers can use it to optimize application performance, scalability, or capacity. Methods which use evidence to sandbox are obsolete and will be removed in a future release of the .NET Framework. Returns The final row (labeled "(Not present)") describes the behavior for incoming rows that don't match any existing row. An assembly or module was loaded twice with two different evidences. There is a set of screens provided and all are in .xaml extensions. The Load method's overwrites the read-only column values, if needed. [in] A sampling index. If the file is not found, the CodeBase property is used to search for the assembly. Loading Elements There are several different ways to load the elements: Use an x:Bind expression to specify the load state. The TextReader used to feed the XML data into the document. If the debugger has not yet loaded DLLName .dll, it loads the DLL at this point if it is located in the current DLL search path. . If the reader is positioned on a leaf node that is invalid for the root level of a document, for example a white space or attribute node, the reader continues to read until it is positioned on a node that can be used for the root. These scenarios describe standard usage for a DataTable, describing its update and merge behavior. Returns Loads an assembly given its display name, loading the assembly into the domain of the caller using the supplied evidence. WebLoad (Stream) Creates a new XDocument instance by using the specified stream. If you specify the OverwriteChanges or PreserveChanges options when calling the Load method, then the assumption is made that the incoming data is coming from the DataTable's primary data source, and the DataTable tracks changes and can propagate the changes back to the data source. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Incremental data feed from secondary data sources. Windows. WebThe Load method provides a technique for filling a single DataTable with data, retrieved from an IDataReader instance. If the assembly is found using CodeBase, the display name is matched against the assembly. This file must be created in advance by using the ; If you have a vector property, apply the VectorType attribute to the property in your data model. In this case, a FileNotFoundException is raised. Exceptions XmlException There is a load or parse error in the XML. An IDataReader that provides a result set. An Azure load balancer is a Layer-4 (TCP, UDP) load balancer that provides high availability by distributing incoming traffic among healthy VMs. The assembly is loaded into the application domain of the caller. Microsoft makes no warranties, express or implied, with respect to the information provided here. The techniques shown in this topic apply equally to models created with Code First and the EF Designer. There is a load or parse error in the XML. Shader Model 4.1 is available in Direct3D 10.1 or higher. The term load balancing refers to the distribution of workloads across multiple computing resources. After each result set, the Load method moves on to the next result set within the reader, until there are no more result sets. In each case, the description indicates the behavior when the primary key of a row in the incoming data matches the primary key of an existing row. This file is in format. To load assemblies into other application domains, use a method such as CreateInstanceAndUnwrap. Applies to See also Introduction to the ASP.NET Page Life Cycle Recommended content UpdatePanel (System.Web.UI) LinkButton (System.Web.UI.WebControls) Web In this scenario, the user wants to take the DataTable filled in the previous scenario and perform an incremental synchronization with the primary data source, preserving modifications made in the DataTable. Execute an extension by issuing the full !DLLName.ExtensionCommand syntax. ; Multiple columns at a time in the form of a vector like HistoricalPrices in the HousingData class. Remarks An IDataReader that provides one or more result sets. If the match fails, a FileLoadException is thrown. Load object The object placeholder represents an object expression that evaluates to an object in the Applies To list. Version 2.0 or later of the common language runtime is currently loaded and assemblyRef was compiled with a later version. The URL can be either a local file or an HTTP URL (a Web address). Loads the XML document from the specified URL. C# public virtual void Load (string filename); Parameters filename String URL for the file containing the XML document to load. WebLoad Event Reference Feedback Definition Namespace: System. Firstly, I want to load a Main Screen file from 'C:\MainScreen.xaml'. If a remote computer is specified, valid root keys are: HKLM and HKU. In addition, a DataTable can accept incremental data from one or more secondary data sources. A FillErrorEventHandler delegate to call when an error occurs while loading data. Loading Elements There are several different ways to load the elements: Use an x:Bind expression to specify the load state. Updates the current version of the row with the value of the incoming row. The object placeholder represents an object expression that evaluates to an object in the Applies To list. Use an overload that does not take an Evidence parameter. For more information, see Row States and Row Versions. This method provides the same functionality, but allows you to load multiple result sets from an IDataReader into multiple tables within a DataSet. The Load extension method works just like ToList except that it avoids the creation of the list altogether. Loads an assembly given its AssemblyName. Given these two hypothetical data sources, a user is likely to require one of the following behaviors: Initialize DataTable from a primary data source. In addition, a partial assembly name can load an assembly from the global assembly cache only if there is an exact copy of the assembly in the application base directory (BaseDirectory or AppDomainSetup.ApplicationBase). WebLoad Event Reference Feedback Definition Namespace: System. Loads an Assembly given its display name. If you want validation to occur, you can create a validating XmlReader instance by using the XmlReaderSettings class and the Create method. A IDataReader that provides a result set. Some information relates to prerelease product that may be substantially modified before its released. With Azure Load Balancer, you can scale your applications and create highly available services. You define a front-end IP configuration that contains one or more public After each result set, the Load method moves on to the next result set within the reader, until there are no more result sets. The following Console application example first creates tables and loads data from a reader into a DataSet, using the Load method. Parameters Object The following sample demonstrates the use of loading a raw assembly. Before you save the document, you must add a root level element, otherwise Save will throw an exception. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. To specify a remote computer, include the computer name (in the format, Specifies the name and path of the file to be loaded. Until an object is visible, a user can't interact with it. The default is false; white space in element content is not preserved. Microsoft makes no warranties, express or implied, with respect to the information provided here. securityEvidence is not null. The assemblies that are loaded into the two application domains might be different if the path settings for the two application domains are different. The object can be manipulated programmatically in its Initialize event procedure. If the DataTable already contains rows, the incoming data from the data source is merged with the existing rows. WebThis occurs because the form values have already been loaded. (If you want finer control over the behavior of incoming data, see DataTable.Load.) Call FindName with the name that you defined on the element. Occurs before a form is displayed for the first time. More info about Internet Explorer and Microsoft Edge, http://go.microsoft.com/fwlink/?LinkID=155570, http://go.microsoft.com/fwlink/?LinkId=155570. You can also access other server controls within the page's control hierarchy. Call GetTemplateChild with the name that you defined on the element. Updates the current and original versions of the row with the value of the incoming row. WebLoad-balancing options. The following example adds a table to a DataSet, and then attempts to use the Load method to load data from a DataTableReader that contains an incompatible schema. Using this delegate mechanism, rather than a simpler try/catch block, allows you to determine the error, handle the situation, and continue processing if you like. Call FindName with the name that you defined on the element. To load an assembly from a byte array with the trust level of the application domain, use the Load(Byte[], Byte[], SecurityContextSource) method overload. It's important to note that all of the elements in the vector Microsoft makes no warranties, express or implied, with respect to the information provided here. WebThis occurs because the form values have already been loaded. In this The Upsert option facilitates aggregating changes from one or more secondary data sources. Microsoft makes no warranties, express or implied, with respect to the information provided here. If the file is not found, CodeBase is used to search for the assembly. If a version of the requested assembly is already loaded, this method returns the loaded assembly, even if a different version is requested. One common way to do this is to write a LINQ query and then call ToList on it, only to immediately discard the created list. Load balancing aims to optimize resource use, maximize throughput, minimize response time, and avoid overloading any single resource. The following table describes the three load options provided by the LoadOption enumeration. Azure Load Testing Preview is a fully managed load-testing service that enables you to generate high-scale load. Use the Show method to make the object visible. Version 2.0 or later of the common language runtime is currently loaded and assemblyString was compiled with a later version. A load balancer health probe monitors a given port on each VM and only distributes traffic to an operational VM. Next steps. In each case, the Action property of the DataRowChangeEventArgs instance passed to the event handler contains information about the particular action associated with the event. Values in a DataColumn can be constrained through use of properties such as ReadOnly and AutoIncrement. The Load method attempts to find a table within the DataSet matching the name found in the array of table names, in order. Parameters Object Loads the Assembly with a common object file format (COFF) based image containing an emitted Assembly. If the DataSet already contains rows, the incoming data from the data source is merged with the existing rows. Some information relates to prerelease product that may be substantially modified before its released. Forms Assembly: System.Windows.Forms.dll Important Some information relates to prerelease product that may be substantially modified before its released. The loadOption parameter allows you to specify how you want the imported data to interact with existing data, and can be any of the values from the LoadOption enumeration. To enable execution of code loaded from remote locations, you can use the configuration element. WebTo load the correct assembly, it's recommended to call the Load method by passing the long form of the assembly name. It's important to note that all of the elements in the vector The URL can be either a local file or an HTTP URL (a Web address). The assembly is loaded into the application domain of the caller. There is a load or parse error in the XML. Using this delegate mechanism, rather than a simpler try/catch block, allows you to determine the error, handle the situation, and continue processing if you like. In each case, the description indicates the behavior when the primary key of a row in the incoming data matches the primary key of an existing row. WebLoad (String) Load (Byte [], Byte []) Overloads Load (Byte []) Loads the Assembly with a common object file format (COFF) based image containing an emitted Assembly. The FillErrorEventArgs parameter supplies a Continue property: set this property to true to indicate that you have handled the error and wish to continue processing. Loads an assembly with the specified name. This example shows how to use one of the overloaded versions of Load. Fills a DataSet with values from a data source using the supplied IDataReader, using an array of strings to supply the names for the tables within the DataSet. This method provides the same functionality, but allows you to load multiple result sets from an IDataReader into multiple tables within a DataSet. WebLoad-balancing options. Valid root keys for the local computer are: HKLM, HKCU, HKCR, HKU, and HKCC. The Upsert option facilitates aggregating changes from one or more secondary data sources. Windows. The expression should return true to load and false to unload the element. Load object The object placeholder represents an object expression that evaluates to an object in the Applies To list. Key scenarios that you can accomplish using Azure Standard Updates the current and original versions of the row with the value of the incoming row. rawAssembly was compiled with a later version of the common language runtime than the version that is currently loaded. filename specified a file that is read-only. The argument type is dependent on the texture-object type. See http://go.microsoft.com/fwlink/?LinkID=155570 for more information. The operation is attempted on an unloaded application domain. This method is provided as a convenience for interoperability callers who cannot call the static Assembly.Load method. Key scenarios that you can accomplish using Azure Standard To load an extension DLL, you can do one of the following: Use the .load or .loadby command. -or-. Be aware that setting the property to false causes the code that triggered the problem to throw an exception. After this file is loaded successfully, I consider to use inside to load another screen from 'C:\SubScreens\Screen1.xaml'. Some information relates to prerelease product that may be substantially modified before its released. Loads an Assembly given its AssemblyName. The rules for assembly and security evidence merging are as follows: When you use a Load method with no Evidence parameter, the assembly is loaded with the evidence that the loader supplies. In the following example, UserForm2 is loaded during UserForm1's Initialize event. The specified path is invalid (for example, it is on an unmapped drive). If the debugger has not yet loaded DLLName .dll, it loads the DLL at this point if it is located in the current DLL search path. WebThe Load method can be used in several common scenarios, all centered around getting data from a specified data source and adding it to the current data container (in this case, a DataTable ). The raw bytes representing the symbols for the Assembly are also loaded. See . The following example loads an assembly given its fully qualified name, and lists all the types contained in the specified assembly. Use the Show method to make the object visible. If both the AssemblyName.Name property and the AssemblyName.CodeBase property are set, the first attempt to load the assembly uses the display name (including version, culture, and so on, as returned by the Assembly.FullName property). The expression should return true to load and false to unload the element. Loads an assembly given its AssemblyName. If a matching table is found, that table is loaded with the content of the current result set. When legacy CAS policy is not enabled, securityEvidence should be null. The Load method makes all these scenarios possible. The name resolution scheme for this method is the same as that followed by the Fill method of the DbDataAdapter class. Version 2.0 or later of the common language runtime is currently loaded and assemblyRef was compiled with a later version. Exceptions XmlException There is a load or parse error in the XML. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. When you use a Load method with a Byte[] parameter and Evidence to load a COFF image, only the supplied evidence is used. This file must be created in advance by using the For more information about handling events, see Handling and Raising Events. ; Multiple columns at a time in the form of a vector like HistoricalPrices in the HousingData class. The value of securityContextSource is not one of the enumeration values. Please see Office VBA support and feedback for guidance about the ways you can receive support and provide feedback. The Load method consumes the first result set from the loaded IDataReader, and after successful completion, sets the reader's position to the next result set, if any. The following example uses the StringReader class to load a string of XML data into the XmlDocument object. Version 2.0 or later of the common language runtime is currently loaded and assemblyString was compiled with a later version. In each case, both events occur, and the action is the same for each. When one or more of the coordinates in Location exceed the u, v, or w mipmap level dimensions of the texture, Load returns zero in all components. Load balancer supports both inbound and outbound scenarios. Direct3D guarantees to return zero for any resource that is accessed out of bounds. Later the user intends to propagate changes back to the primary data source. Using partial names has a negative effect on performance. This occurs because the form values have already been loaded. If the match fails, a FileLoadException is thrown. The table below provides the details. The caller does not have the required permission. The DataTable isn't responsible for tracking changes in order to allow synchronization with the secondary data source. A texture-object type (except TextureCube or TextureCubeArray). Firstly, I want to load a Main Screen file from 'C:\MainScreen.xaml'. Load balancer provides low latency and high throughput, and scales up to millions of flows for all TCP and UDP applications. Load balancing aims to optimize resource use, maximize throughput, minimize response time, and avoid overloading any single resource. This method provides the same functionality, but allows you to load multiple result sets from an IDataReader into multiple tables within a DataSet. The Load method provides a technique for filling a single DataTable with data, retrieved from an IDataReader instance. For example, "ProcessorArchitecture=msil". This method uses a 0-based coordinate system and not a 0.0-1.0 UV system. This method automatically detects the string format of the input XML (for example, UTF-8, ANSI, and so on). The FillErrorEventArgs parameter passed to the procedure provides properties that allow you to retrieve information about the error that occurred, the current row of data, and the DataTable being filled. WebLoad-balancing options. The loader does not continue probing for other assemblies that match the simple name. The assembly is loaded into the domain of the caller using the supplied evidence. Execute an extension by issuing the full !DLLName.ExtensionCommand syntax. filename is a zero-length string, contains only white space, or contains one or more invalid characters as defined by InvalidPathChars. An array of DataTable instances, from which the Load(IDataReader, LoadOption, DataTable[]) method retrieves name and namespace information. Specifies the name and path of the file to be loaded. For example, to access a 2D texture, supply integer texel coordinates for the first two components and a mipmap level for the third component. The Load method always preserves significant white space. In addition, a DataSet can accept incremental data from one or more secondary data sources. [in] The texture coordinates; the last component specifies the mipmap level. Forms Assembly: System.Windows.Forms.dll Important Some information relates to prerelease product that may be substantially modified before its released. The first is taken from a Windows Forms data binding application where Load is used to C# public System.Reflection.Assembly Load (byte[] rawAssembly); Parameters rawAssembly Byte [] An array of type byte that is a COFF-based image containing an emitted assembly. The URL can be either a local file or an HTTP URL (a Web address). WebLoad (Stream) Creates a new XDocument instance by using the specified stream. Some information relates to prerelease product that may be substantially modified before its released. To run the example, paste the following code in a form called Form1 containing a Button called Button1 and two Label controls called Label1 and Label2. In this example, because the parameters passed to the Load method indicate a table name that does not exist, the Load method creates a new table to match the name passed as a parameter. The Load method handles such columns in a manner that is consistent with the behavior defined by the column's properties. Set the property to false to indicate that you wish to halt processing. Microsoft makes no warranties, express or implied, with respect to the information provided here. The following example loads the last book node of the books.xml file into the XML document. C# public virtual void Load (string filename); Parameters filename String URL for the file containing the XML document to load. . When you use a Load method overload with a Byte[] parameter to load a COFF image, evidence is inherited from the calling assembly. The action may be applied to either the current or original version of each row, or both, depending on the current row state. An I/O error occurred while opening the file. If the current node and its siblings look like the following: Load succeeds, but you have an incomplete DOM tree because there is no root level element. The loader does not continue probing for other assemblies that match the simple name. In general, the PreserveChanges and OverwriteChanges options are intended for scenarios in which the user needs to synchronize the DataSet and its changes with the primary data source. The example then displays the full name of the assembly's public types. A byte array that is a COFF-based image containing an emitted assembly. Be aware that setting the property to false causes the code that triggered the problem to throw an exception. The return values for the reg load operation are: To load the file named TempHive.hiv to the key HKLM\TempHive, type: More info about Internet Explorer and Microsoft Edge, Specifies the full path of the subkey to be loaded. The assembly is loaded into the application domain of the caller. The errorHandler parameter is a FillErrorEventHandler delegate that refers to a procedure that is called when an error occurs while loading data. In this scenario, the user wants to take the DataSet filled in the previous scenario and perform an incremental synchronization with the primary data source, preserving modifications made in the DataSet. The schema operations take place for all imported result sets, even those containing no data. The action may be applied to either the current or original version of each row, or both, depending on the current row state. See http://go.microsoft.com/fwlink/?LinkID=155570 for more information. Remarks When an object is loaded, it is placed in memory, but isn't visible. More info about Internet Explorer and Microsoft Edge, Reading XML Data using XPathDocument and XmlDocument. The Load extension method works just like ToList except that it avoids the creation of the list altogether. For information about the disadvantages of using the load-from context, see the Assembly.LoadFrom method overload or Best Practices for Assembly Loading. Pieces of evidence supplied as an argument to the Load method supersede pieces of evidence supplied by the loader.
