WebLoad-balancing options. The return type matches the type in the Object declaration. An object that describes the assembly to load. The example then displays the full name of the assembly's public types. 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. 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. Some information relates to prerelease product that may be substantially modified before its released. In this case, the document remains empty. The load operation will fail with an InvalidOperationException if any of the source data columns in the incoming reader are computed columns. See . The URL can be either a local file or an HTTP URL (a Web address). These values may be equivalent, or may be different if the data in the row has been changed since filling the DataTable. This method should be used only to load an assembly into the current application domain. To preserve the .reloc address for your C++ executable file, specify /fixed:no when you are linking. You define a front-end IP configuration that contains one or more public 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. More info about Internet Explorer and Microsoft Edge, http://go.microsoft.com/fwlink/?LinkID=155570, http://go.microsoft.com/fwlink/?LinkId=155570. Parameters Object Forms Assembly: System.Windows.Forms.dll Important Some information relates to prerelease product that may be substantially modified before its released. This method provides the same functionality, but allows you to load multiple result sets from an IDataReader into multiple tables within a DataSet. A load balancer health probe monitors a given port on each VM and only distributes traffic to an operational VM. It corresponds to the assembly's FullName property. Microsoft makes no warranties, express or implied, with respect to the information provided here. The service simulates traffic for your applications, regardless of where they're hosted. The operation is attempted on an unloaded application domain. This method is obsolete and will be removed in a future release of the .NET Framework. If the assembly is found using CodeBase, the display name is matched against the assembly. This method uses a 0-based coordinate system and not a 0.0-1.0 UV system. In the .NET Framework version 2.0, processor architecture is added to assembly identity, and can be specified as part of assembly name strings. Given these two hypothetical data sources, a user is likely to require one of the following behaviors: Initialize DataSet from a primary data source. 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. The object placeholder represents an object expression that evaluates to an object in the Applies To list. Use the Show method to make the object visible. The stream containing the XML document to load. The final row (labeled "(Not present)") describes the behavior for incoming rows that don't match any existing row. After this file is loaded successfully, I consider to use inside to load another screen from 'C:\SubScreens\Screen1.xaml'. Execute an extension by issuing the full !DLLName.ExtensionCommand syntax. Zone, Url and Site are inherited from the calling assembly, and Hash and StrongName are taken from the COFF assembly. 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. The techniques shown in this topic apply equally to models created with Code First and the EF Designer. Reflecting on C++ executable files might throw a BadImageFormatException. WebTo load the correct assembly, it's recommended to call the Load method by passing the long form of the assembly name. filename specified a file that is read-only. 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. -or-. 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 ). Here are two examples of using Load. Developers, testers, and quality assurance (QA) engineers can use it to optimize application performance, scalability, or capacity. Version 2.0 or later of the common language runtime is currently loaded and assemblyRef was compiled with a later version. A file that was found could not be loaded. Let me explain it again. Some information relates to prerelease product that may be substantially modified before its released. The example then focuses on data issues, including handling the various loading options. This method is a Microsoft extension to the Document Object Model (DOM). The expression should return true to load and false to unload the element. Shader Model 4.1 is available in Direct3D 10.1 or higher. typeX denotes that there are four possible types: int, int2, int3 or int4. This applies to the .NET Framework version 1.1 Service Pack 1 (SP1) and subsequent releases. 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. Be aware that setting the property to false causes the code that triggered the problem to throw an exception. The following example demonstrates several of the issues involved with calling the Load method. When converting data, the Load method uses the same conversion rules as the Fill method. To enable execution of code loaded from remote locations, you can use the configuration element. Updates the current and original versions of the row with the value of the incoming row. Otherwise, the Load method uses the current version of the primary key field. This method allows you to specify a load option parameter, indicating how rows already in a DataTable combine with rows being loaded. Methods which use evidence to sandbox are obsolete and will be removed in a future release of the .NET Framework. Updates the current version of the row with the value of the incoming row. 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. With Azure Load Balancer, you can scale your applications and create highly available services. The first is taken from a Windows Forms data binding application where Load is used to Updates the current and original versions of the row with the value of the incoming row. WebLoad (String) Loads the XML document from the specified URL. The Load extension method works just like ToList except that it avoids the creation of the list altogether. This file is in format. 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; set the property to false to indicate that you wish to halt processing. 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 Load method always preserves significant white space. Some information relates to prerelease product that may be substantially modified before its released. Loads an Assembly given its display name. Load balancer provides low latency and high throughput, and scales up to millions of flows for all TCP and UDP applications. The service simulates traffic for your applications, regardless of where they're hosted. The Load extension method works just like ToList except that it avoids the creation of the list altogether. WebThe Load method provides a technique for filling a single DataTable with data, retrieved from an IDataReader instance. Specifies the name and path of the file to be loaded. The following table displays behavior for the Load method. 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. Notifies the server control to perform any processing steps that are set to occur on each page request. Windows. Returns XDocument An XDocument object that reads the data that is contained in the stream. Values in a DataColumn can be constrained through use of properties such as ReadOnly and AutoIncrement. An assembly or module was loaded twice with two different evidences. Load columns as: Individual columns like Size and CurrentPrices in the HousingData class. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. An array of type byte containing the raw bytes representing the symbols for the assembly. 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. The Load method makes all these scenarios possible. Here are two examples of using Load. 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. 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. An IDataReader that provides a result set. securityEvidence is not null. Fills a DataSet with values from a data source using the supplied IDataReader. Loads the Assembly with a common object file format (COFF) based image containing an emitted Assembly. Load balancer supports both inbound and outbound scenarios. This file must be created in advance by using the 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. If rawSymbolStore was specified, the raw bytes that represent the symbols for the assembly are also loaded. Here are two examples of using Load. An IDataReader that provides one or more result sets. 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. If you need to use a XmlDocument object to work with XML, you can use the XmlTextReader object to create one. 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. (If you want finer control over the behavior of incoming data, see DataTable.Load.) Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. The final row (labeled "(Not present)") describes the behavior for incoming rows that don't match any existing row. Call FindName with the name that you defined on the element. Specifies the name and path of the file to be loaded. The expression should return true to load and false to unload the element. In this case, a FileNotFoundException is raised. Loading Elements There are several different ways to load the elements: Use an x:Bind expression to specify the load state. For this code example to run, you must provide the fully qualified assembly name. C# Copy public static System.Xml.Linq.XDocument Load (System.IO.Stream stream); Parameters stream Stream The stream that contains the XML data. 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. This action value depends on the state of the row before the load operation. Fills a DataTable with values from a data source using the supplied IDataReader. The Load method must take into account three specific issues when loading the data from an IDataReader instance: schema, data, and event operations. ; If you have a vector property, apply the VectorType attribute to the property in your data model. These scenarios describe standard usage for a DataTable, describing its update and merge behavior. If the current node and its siblings look like the following: Load throws an exception because a document cannot have two root level elements. In this case, the method doesn't allow you to indicate the load option, and uses the default, PreserveChanges. Returns Parameters Object Fills a DataTable with values from a data source using the supplied IDataReader. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Occurs before a form is displayed for the first time. The read only constraint on a DataColumn is applicable only for changes that occur in memory. WebThe Load method provides a technique for filling a single DataTable with data, retrieved from an IDataReader instance. WebLoad (Stream) Creates a new XDocument instance by using the specified stream. 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. Version 2.0 or later of the common language runtime is currently loaded and assemblyRef was compiled with a later version. 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. You can also access other server controls within the page's control hierarchy. The name resolution scheme for this method is the same as that followed by the Fill method of the DbDataAdapter class.
