The service simulates traffic for your applications, regardless of where they're hosted. Writes saved subkeys and entries into a different subkey in the registry. A DataTable synchronizes or updates with a single primary data source. Microsoft makes no warranties, express or implied, with respect to the information provided here. For example, "ProcessorArchitecture=msil". The first is taken from a Windows Forms data binding application where Load is used to For this code example to run, you must provide the fully qualified assembly name. In this case, the document remains empty. 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. Until an object is visible, a user can't interact with it. Load balancer supports both inbound and outbound scenarios. The loader does not continue probing for other assemblies that match the simple name. 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. 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. If the DataSet already contains rows, the incoming data from the data source is merged with the existing rows. Instead, the common language runtime tries to load the assembly into the calling application domain. There is a set of screens provided and all are in .xaml extensions. 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. 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. Load object The object placeholder represents an object expression that evaluates to an object in the Applies To list. The XmlReader used to feed the XML data into the document. The DataSet tracks changes, allowing synchronization with the primary data source. The following example loads an assembly given its fully qualified name, and lists all the types contained in the specified assembly. 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. These values may be equivalent, or may be different if the data in the row has been changed since filling the DataTable. The example then calls the Load method, displaying the data both before and after the load operation. Remarks When you use a Load method with a Byte[] parameter and Evidence to load a COFF image, only the supplied evidence is used. Occurs before a form is displayed for the first time. Use the Show method to make the object visible. The file specified in filename was not found. 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. See the documentation for the Load method for more information on using this parameter. A good example of this is loading entities for data binding as described in Local Data. Version 2.0 or later of the common language runtime is currently loaded and assemblyRef was compiled with a later version. The Load method handles such columns in a manner that is consistent with the behavior defined by the column's properties. These issues, and more, are controlled by the loadOption parameter. When you use a Load method overload with a Byte[] parameter to load a COFF image, evidence is inherited from the calling assembly. Loads the XML document from the specified stream. A load balancer health probe monitors a given port on each VM and only distributes traffic to an operational VM. Please use an overload of Load which does not take an Evidence parameter. Developers, testers, and quality assurance (QA) engineers can use it to optimize application performance, scalability, or capacity. Loads the specified XML data from a Stream, a URL, a TextReader, or an XmlReader. Set the property to false to indicate that you wish to halt processing. Fills a DataTable with values from a data source using the supplied IDataReader. The loader does not continue probing for other assemblies that match the simple name. 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. WebLoad (String) Loads the XML document from the specified URL. Reflecting on C++ executable files might throw a BadImageFormatException. WebLoad (String) Load (Byte [], Byte []) Overloads Load (Byte []) Loads the Assembly with a common object file format (COFF) based image containing an emitted Assembly. 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. In this case, the method doesn't allow you to indicate the load option, and uses the default, PreserveChanges. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. filename specified a file that is read-only. In this case, a FileNotFoundException is raised. To load an assembly from a byte array with the trust level of the application domain, use the Load(Byte[], Byte[], SecurityContextSource) method overload. Preserve changes and re-synchronize from the primary data source. Azure Load Testing Preview is a fully managed load-testing service that enables you to generate high-scale load. 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 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. 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. Updates the original version of the row with the value of the incoming row. The following table displays behavior for the Load method when called with each of the LoadOption values, and also shows how the values interact with the row state for the row being loaded. A load balancer health probe monitors a given port on each VM and only distributes traffic to an operational VM. The read only constraint on a DataColumn is applicable only for changes that occur in memory. You define a front-end IP configuration that contains one or more public Some information relates to prerelease product that may be substantially modified before its released. The assembly is loaded into the application domain of the caller. An IDataReader that provides one or more result sets. More info about Internet Explorer and Microsoft Edge, Reading XML Data using XPathDocument and XmlDocument. If a remote computer is specified, valid root keys are: HKLM and HKU. This method is a Microsoft extension to the Document Object Model (DOM). The final row (labeled "(Not present)") describes the behavior for incoming rows that don't match any existing row. The URL can be either a local file or an HTTP URL (a Web address). Fills a DataTable with values from a data source using the supplied IDataReader. Next steps. Instead, the assembly is loaded using load-from rules. 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. (The overload that doesn't allow you to specify the behavior uses the default load option.) The errorHandler parameter is a FillErrorEventHandler delegate that refers to a procedure that is called when an error occurs while loading data. Here are two examples of using Load. Let me explain it again. This file is in format. Should it modify current values, original values, or both? 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 object can be manipulated programmatically in its Initialize event procedure. WebLoad-balancing options. FileLoadException is thrown if assemblyRef specifies the full assembly name and the first assembly that matches the simple name has a different version, culture, or public key token. Notifies the server control to perform any processing steps that are set to occur on each page request. 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. The caller does not have the required permission. -or-. 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 DataTable). Loads an assembly given its AssemblyName. 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. Call GetTemplateChild with the name that you defined on the element. The expression should return true to load and false to unload the element. This method automatically detects the string format of the input XML (for example, UTF-8, ANSI, and so on). The long or short form of the assembly name. The following table displays behavior for the Load method. The example uses the file, books.xml, as input. This has the following results. The assembly is loaded into the application domain of the caller. 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. For information about how to obtain the fully qualified assembly name, see Assembly Names. Loads the assembly with a common object file format (COFF)-based image containing an emitted assembly, optionally including symbols and evidence for the assembly. The techniques shown in this topic apply equally to models created with Code First and the EF Designer. Loads the Assembly with a common object file format (COFF) based image containing an emitted Assembly. The following example demonstrates how to use the SetDesktopLocation, Load, Activated, and Activate members. assemblyRef is not a valid assembly. 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. (If you want finer control over the behavior of incoming data, see DataTable.Load.) Please use an overload of Load which does not take an Evidence parameter. In this method call, the specified LoadOption parameter influences the processing of the incoming data. More info about Internet Explorer and Microsoft Edge. If the reader is already positioned on some node at depth "n", this method loads that node and all subsequent siblings up to the end tag that closes depth "n". The default is false; white space in element content is not preserved. . If the current AppDomain object represents application domain A, and the Load method is called from application domain B, the assembly is loaded into both application domains. These values may be equivalent, or may be different if the data in the row has been changed since filling the DataTable. You can use this event to perform tasks such as allocating resources used by the form. 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 term load balancing refers to the distribution of workloads across multiple computing resources. When working with the schema, the Load method may encounter conditions as described in the following table. 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. For information about how to obtain the fully qualified assembly name, see Assembly Names. Updates the current version of the row with the value of the incoming row. When converting data, the Load method uses the same conversion rules as the DbDataAdapter.Fill method. Forms Assembly: System.Windows.Forms.dll Important Some information relates to prerelease product that may be substantially modified before its released. The load operation will fail with an InvalidOperationException if any of the source data columns in the incoming reader are computed columns. The URL can be either a local file or an HTTP URL (a Web address). 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. The following sample demonstrates the use of loading a raw assembly. You define a front-end IP configuration that contains one or more public Loads an assembly given its AssemblyName. If the DataTable already contains rows, the incoming data from the data source is merged with the existing rows according to the value of the loadOption parameter. To load an extension DLL, you can do one of the following: Use the .load or .loadby command. This file is in format. When converting data, the Load method uses the same conversion rules as the Fill method. Load balancing aims to optimize resource use, maximize throughput, minimize response time, and avoid overloading any single resource. An array of type byte that is a COFF-based image containing an emitted assembly. Version 2.0 or later of the common language runtime is currently loaded and assemblyRef was compiled with a later version. The display name of the assembly. See AssemblyName.ProcessorArchitecture. 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. The following example instantiates an AssemblyName object and uses it to load the sysglobal.dll assembly. If the match fails, a FileLoadException is thrown. This example shows how to use one of the overloaded versions of Load. First, the example focuses on schema issues, including inferring a schema from the loaded IDataReader, and then handling incompatible schemas, and schemas with missing or additional columns. 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. 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. With Azure Load Balancer, you can scale your applications and create highly available services. See http://go.microsoft.com/fwlink/?LinkID=155570 for more information. 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. The TextReader used to feed the XML data into the document. Forms Assembly: System.Windows.Forms.dll Important Some information relates to prerelease product that may be substantially modified before its released. The following example uses the StringReader class to load a string of XML data into the XmlDocument object.
