The Load method always preserves significant white space. When legacy CAS policy is not enabled, securityEvidence should be null. The final row (labeled "(Not present)") describes the behavior for incoming rows that don't match any existing row. 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. 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. 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 following example demonstrates several of the issues involved with calling the Load method. Call GetTemplateChild with the name that you defined on the element. C# public virtual void Load (string filename); Parameters filename String URL for the file containing the XML document to load. Next steps. The errorHandler parameter is a FillErrorEventHandler delegate that refers to a procedure that is called when an error occurs while loading data. 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. In this case, a FileNotFoundException is raised. Some information relates to prerelease product that may be substantially modified before its released. Let me explain it again. Not supported for other textures. The loader does not continue probing for other assemblies that match the simple name. (The overload that doesn't allow you to specify the behavior uses the default load option.) It's important to note that all of the elements in the vector When you use a Load method with a Byte[] parameter and Evidence to load a COFF image, only the supplied evidence is used. The offset type is dependent on the texture-object type, and needs to be static. The output is displayed in the console window. 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. Do not use an AssemblyName with only the CodeBase property set. You can use this event to perform tasks such as allocating resources used by the form. Remarks Valid root keys for the local computer are: HKLM, HKCU, HKCR, HKU, and HKCC. 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. Please use an overload of Load which does not take an Evidence parameter. Until an object is visible, a user can't interact with it. Returns XDocument An XDocument object that reads the data that is contained in the stream. 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. Load balancer supports both inbound and outbound scenarios. Loads an assembly with the specified 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 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. Zone, Url and Site are inherited from the calling assembly, and Hash and StrongName are taken from the COFF assembly. In this There is a load or parse error in the XML. 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. 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). Microsoft makes no warranties, express or implied, with respect to the information provided here. Microsoft makes no warranties, express or implied, with respect to the information provided here. Evidence of the calling assembly and evidence of the COFF image are ignored. Version 2.0 or later of the common language runtime is currently loaded and rawAssembly was compiled with a later version. The following Console application example first creates tables and loads data from a reader into a DataSet, using the Load method. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. 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 DataTable tracks changes, allowing synchronization with the primary data source. You define a front-end IP configuration that contains one or more public Occurs when the server control is loaded into the Page object. Loads an assembly given its display name, loading the assembly into the domain of the caller using the supplied evidence. This action value depends on the state of the row before the load operation. 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. If the DataTable already contains rows, the incoming data from the data source is merged with the existing rows. Updates the current and original versions of the row with the value of the incoming row. The trust level of an assembly that is loaded by using this method is the same as the trust level of the calling assembly. For more information, see Reading XML Data using XPathDocument and XmlDocument. The URL can be either a local file or an HTTP URL (a Web address). 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. 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. For more information, see the Remarks section of the XmlReader reference page. WebLoad-balancing options. After this file is loaded successfully, I consider to use inside to load another screen from 'C:\SubScreens\Screen1.xaml'. The errorHandler parameter is a FillErrorEventHandler delegate that refers to a procedure that is called when an error occurs while loading data. Instead, the assembly is loaded using load-from rules. 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. These scenarios describe standard usage for a DataTable, describing its update and merge behavior. The load operation will fail with an InvalidOperationException if any of the source data columns in the incoming reader are computed columns. If a matching table is found, that table is loaded with the content of the current result set. The term load balancing refers to the distribution of workloads across multiple computing resources. 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. To load an extension DLL, you can do one of the following: Use the .load or .loadby command. 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. Fills a DataTable with values from a data source using the supplied IDataReader using an error-handling delegate. Use the Show method to make the object visible. The raw bytes representing the symbols for the Assembly are also loaded. 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. 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 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. Load columns as: Individual columns like Size and CurrentPrices in the HousingData class. Updates the current version of the row with the value of the incoming row. A good example of this is loading entities for data binding as described in Local Data. The Load method must take into account three specific issues when loading the data from an IDataReader instance: schema, data, and event operations. Use the Show method to make the object visible. An array of type byte that is a COFF-based image containing an emitted assembly. 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. When working with the schema, the Load method may encounter conditions as described in the following table. A texture-object type (except TextureCube or TextureCubeArray). Incremental data feed from secondary data sources. (A partial name omits one or more of culture, version, or public key token. 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. (If you want finer control over the behavior of incoming data, see DataTable.Load.) The Load method fills each supplied DataTable instance with data from a single result set from the source data reader. See Row States and Row Versions for more information. Key scenarios that you can accomplish using Azure Standard If the registry key name contains a space, enclose the key name in quotes. 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. 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. To load assemblies into other application domains, use a method such as CreateInstanceAndUnwrap. 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. . More info about Internet Explorer and Microsoft Edge, http://go.microsoft.com/fwlink/?LinkID=155570, http://go.microsoft.com/fwlink/?LinkId=155570. A IDataReader that provides a result set. Firstly, I want to load a Main Screen file from 'C:\MainScreen.xaml'. 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. If rawSymbolStore was specified, the raw bytes that represent the symbols for the assembly are also loaded. This method provides the same functionality, but allows you to load multiple result sets from an IDataReader into multiple tables within a DataSet. Some information relates to prerelease product that may be substantially modified before its released.
