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 array of type byte that is a COFF-based image containing an emitted assembly. 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. Load balancer supports both inbound and outbound scenarios. 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). Shader Model 4.1 is available in Direct3D 10.1 or higher. This file is in
format. WebThe Load method provides a technique for filling a single DataTable with data, retrieved from an IDataReader instance. Load balancing aims to optimize resource use, maximize throughput, minimize response time, and avoid overloading any single resource. Given these two hypothetical data sources, a user is likely to require one of the following behaviors: Initialize DataTable from a primary data source. A byte array that is a COFF-based image containing an emitted assembly. Version 2.0 or later of the common language runtime is currently loaded and assemblyString was compiled with a later version. The TextReader used to feed the XML data into the document. The following Console application example first creates tables and loads data from a reader into a DataSet, using the Load method. 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). 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 long or short form of the assembly name. Let me explain it again. An IDataReader that provides one or more result sets. 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. 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. If the registry key name contains a space, enclose the key name in quotes. 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 Azure Load Testing Preview is a fully managed load-testing service that enables you to generate high-scale load. Loads an assembly given its AssemblyName. The example then adds tables to a DataSet and attempts to fill the tables with data from a DataTableReader. Fills a DataTable with values from a data source using the supplied IDataReader. See http://go.microsoft.com/fwlink/?LinkId=155570 for more information. The name resolution scheme for this method is the same as that followed by the Fill method of the DbDataAdapter class. This method uses a 0-based coordinate system and not a 0.0-1.0 UV system. 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. You define a front-end IP configuration that contains one or more public The stream containing the XML document to load. Version 2.0 or later of the common language runtime is currently loaded and assemblyRef was compiled with a later version. typeX denotes that there are four possible types: int, int2, int3 or int4. Use the Show method to make the object visible. 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. This method is a Microsoft extension to the Document Object Model (DOM). C# Copy public static System.Xml.Linq.XDocument Load (System.IO.Stream stream); Parameters stream Stream The stream that contains the XML data. For this code example to run, you must provide the fully qualified assembly name. 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 the DataSet already contains rows, the incoming data from the data source is merged with the existing rows. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. For example, to access a 2D texture, supply integer texel coordinates for the first two components and a mipmap level for the third component. 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. In this case, the method doesn't allow you to indicate the load option, and uses the default, PreserveChanges. In this More info about Internet Explorer and Microsoft Edge, Load(Byte[], Byte[], SecurityContextSource), http://go.microsoft.com/fwlink/?LinkID=155570. A byte array that contains the raw bytes representing the symbols for the assembly. The following table describes the three load options provided by the LoadOption enumeration. An object that describes the assembly to load. The first is taken from a Windows Forms data binding application where Load is used to 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. See http://go.microsoft.com/fwlink/?LinkID=155570 for more information. Fills a DataSet with values from a data source using the supplied IDataReader. WebLoad Event Reference Feedback Definition Namespace: System. Have questions or feedback about Office VBA or this documentation? After this file is loaded successfully, I consider to use
inside to load another screen from 'C:\SubScreens\Screen1.xaml'. The default namespace associated with DataSet, if any, is associated with each newly created DataTable. WebLoad (String) Loads the XML document from the specified URL. With Azure Load Balancer, you can scale your applications and create highly available services. Preserve changes and re-synchronize from the primary data source. There is a set of screens provided and all are in .xaml extensions. The DataTable isn't responsible for tracking changes in order to allow synchronization with the secondary data source. 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.) 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. In this scenario, the user wants to initialize an empty DataTable with values from the primary data source. Load balancer supports both inbound and outbound scenarios. ; If you have a vector property, apply the VectorType attribute to the property in your data model. See the documentation for the DataTableLoad method for more information on using this parameter. 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. When converting data, the Load method uses the same conversion rules as the DbDataAdapter.Fill method. assemblyRef is not a valid assembly. Remarks The load operation will fail with an InvalidOperationException if any of the source data columns in the incoming reader are computed columns. WebThis occurs because the form values have already been loaded. Loads an Assembly given its AssemblyName. The DataSet isn't responsible for tracking changes in order to allow synchronization with the secondary data source. 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. WebThe Load method provides a technique for filling a single DataTable with data, retrieved from an IDataReader instance. The loader does not continue probing for other assemblies that match the simple name. When you use a Load method overload with a Byte[] parameter to load a COFF image, evidence is inherited from the calling assembly. It's important to note that all of the elements in the vector 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. 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. The service simulates traffic for your applications, regardless of where they're hosted. The raw bytes representing the symbols for the Assembly are also loaded. 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. The errorHandler parameter is a FillErrorEventHandler delegate that refers to a procedure that is called when an error occurs while loading data. The following table describes the three load options provided by the LoadOption enumeration. In each case, both events occur, and the action is the same for each. An assembly or module was loaded twice with two different evidences. Be aware that setting the property to false causes the code that triggered the problem to throw an exception. The Load extension method works just like ToList except that it avoids the creation of the list altogether. filename is a zero-length string, contains only white space, or contains one or more invalid characters as defined by InvalidPathChars. This applies to the .NET Framework version 1.1 Service Pack 1 (SP1) and subsequent releases. Next steps. Loads an Assembly into this application domain. Updates the original version of the row with the value of the incoming row. Evidence of the calling assembly and evidence of the COFF image are ignored. The final row (labeled "(Not present)") describes the behavior for incoming rows that don't match any existing row. This method provides the same functionality, but allows you to load multiple result sets from an IDataReader into multiple tables within a DataSet. Instead, the assembly is loaded using load-from rules. This partial code example is from the Paint.fx file in the AdvancedParticles Sample. To specify a remote computer, include the computer name (in the format, Specifies the name and path of the file to be loaded. A load balancer health probe monitors a given port on each VM and only distributes traffic to an operational VM. This method provides the same functionality, but allows you to load multiple result sets from an IDataReader into multiple tables within a DataSet. See FullName. Updates the current and original versions of the row with the value of the incoming row. If the registry key name contains a space, enclose the key name in quotes. 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. An Azure load balancer is a Layer-4 (TCP, UDP) load balancer that provides high availability by distributing incoming traffic among healthy VMs. The service simulates traffic for your applications, regardless of where they're hosted. Fills a DataTable with values from a data source using the supplied IDataReader using an error-handling delegate. Call GetTemplateChild with the name that you defined on the element. Returns XDocument An XDocument object that reads the data that is contained in the stream. This action value depends on the state of the row before the load operation. Evidence of the calling assembly and evidence of the COFF image is ignored. You define a front-end IP configuration that contains one or more public Specifies the name and path of the file to be loaded. ; Multiple columns at a time in the form of a vector like HistoricalPrices in the HousingData class. assemblyRef specifies a remote assembly, but the ability to execute code in remote assemblies is disabled. More info about Internet Explorer and Microsoft Edge, Reading XML Data using XPathDocument and XmlDocument. If a version of the requested assembly is already loaded, this method returns the loaded assembly, even if a different version is requested. It's important to note that all of the elements in the vector There is a load or parse error in the XML. Use the Show method to make the object visible. The example then calls the Load method, displaying the data both before and after the load operation. Use an overload that does not take an Evidence parameter. Here are two examples of using Load. [in] A sampling index. Required for multi-sample textures. Updates the current version of the row with the value of the incoming row. 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. Remarks Using partial names has a negative effect on performance. This version of the Load method attempts to preserve the current values in each row, leaving the original value intact. WebThis occurs because the form values have already been loaded. The techniques shown in this topic apply equally to models created with Code First and the EF Designer. Version 2.0 or later of the common language runtime is currently loaded and assemblyRef was compiled with a later version. More info about Internet Explorer and Microsoft Edge, Introduction to the ASP.NET Page Life Cycle. 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. WebLoad (String) Load (Byte [], Byte []) Overloads Load (Byte []) Loads the Assembly with a common object file format (COFF) based image containing an emitted Assembly. typeX denotes that there are four possible types: int, int2, int3 or int4. 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. 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. 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 ). WebLoad (String) Loads the XML document from the specified URL. These scenarios describe standard usage for a DataTable, describing its update and merge behavior. Be aware that setting the property to false causes the code that triggered the problem to throw an exception. WebTo load the correct assembly, it's recommended to call the Load method by passing the long form of the assembly name. The assembly is loaded into the application domain of the caller using the specified source for the security context. Remarks When an object is loaded, it is placed in memory, but isn't visible. Firstly, I want to load a Main Screen file from 'C:\MainScreen.xaml'. The techniques shown in this topic apply equally to models created with Code First and the EF Designer. 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". For information about the disadvantages of using the load-from context, see the Assembly.LoadFrom method overload or Best Practices for Assembly Loading. Forms Assembly: System.Windows.Forms.dll Important Some information relates to prerelease product that may be substantially modified before its released. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. In addition, a DataTable can accept incremental data from one or more secondary data sources. Remarks When an object is loaded, it is placed in memory, but isn't visible. The final row (labeled "(Not present)") describes the behavior for incoming rows that don't match any existing row. Updates the current version of the row with the value of the incoming row.
