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. Note that this method overload always creates a new Assembly object with its own mapping. 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. WebLoad (Stream) Creates a new XDocument instance by using the specified stream. Valid root keys for the local computer are: HKLM, HKCU, HKCR, HKU, and HKCC. The following Console application example first creates tables and loads data from a reader into a DataSet, using the Load method. 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. In this These values may be equivalent, or may be different if the data in the row has been changed since filling the DataTable. (If you want finer control over the behavior of incoming data, see DataTable.Load.) Fills a DataSet with values from a data source using the supplied IDataReader. An Azure load balancer is a Layer-4 (TCP, UDP) load balancer that provides high availability by distributing incoming traffic among healthy VMs. URL for the file containing the XML document to load. Reflecting on C++ executable files might throw a BadImageFormatException. The Load extension method works just like ToList except that it avoids the creation of the list altogether. You define a front-end IP configuration that contains one or more public C# Copy public static System.Xml.Linq.XDocument Load (System.IO.Stream stream); Parameters stream Stream The stream that contains the XML data. Preserve changes and re-synchronize from the primary data source. The first is taken from a Windows Forms data binding application where Load is used to Version 2.0 or later of the common language runtime is currently loaded and assemblyString was compiled with a later version. Preserve changes and re-synchronize from the primary data source. These scenarios describe standard usage for a DataTable, describing its update and merge behavior. assemblyRef specifies a remote assembly, but the ability to execute code in remote assemblies is disabled. 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. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. This method provides the same functionality, but allows you to load multiple result sets from an IDataReader into multiple tables within a DataSet. filename is a zero-length string, contains only white space, or contains one or more invalid characters as defined by InvalidPathChars. You define a front-end IP configuration that contains one or more public If rawSymbolStore was specified, the raw bytes that represent the symbols for the assembly are also loaded. 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. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. 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 loads an assembly given its fully qualified name, and lists all the types contained in the specified 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. This occurs because the form values have already been loaded. These values may be equivalent, or may be different if the data in the row has been changed since filling the DataTable. Developers, testers, and quality assurance (QA) engineers can use it to optimize application performance, scalability, or capacity. C# public virtual void Load (string filename); Parameters filename String URL for the file containing the XML document to load. The read only constraint on a DataColumn is applicable only for changes that occur in memory. The Load method attempts to find a table within the DataSet matching the name found in the array of table names, in order. Load columns as: Individual columns like Size and CurrentPrices in the HousingData class. In the following example, UserForm2 is loaded during UserForm1's Initialize event. Azure Load Testing Preview is a fully managed load-testing service that enables you to generate high-scale load. For example, a Texture2D object that was declared as "Texture2d myTexture;" has a return value of type uint4. More info about Internet Explorer and Microsoft Edge. typeX denotes that there are four possible types: int, int2, int3 or int4. If the current node and its siblings look like the following: Load throws an exception because a document cannot have two root level elements. With Azure Load Balancer, you can scale your applications and create highly available services. ; Multiple columns at a time in the form of a vector like HistoricalPrices in the HousingData class. The expression should return true to load and false to unload the element. 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 DataSet isn't responsible for tracking changes in order to allow synchronization with the secondary data source. There are several scenarios where you may want to load entities from the database into the context without immediately doing anything with those entities. An object that describes the assembly to load. Until an object is visible, a user can't interact with it. When working with the schema, the Load method may encounter conditions as described in the following table. Loads an Assembly into this application domain. In this scenario, the user wants to initialize an empty DataSet with values from the 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). The URL can be either a local file or an HTTP URL (a Web address). WebThe Load method provides a technique for filling a single DataTable with data, retrieved from an IDataReader instance. In this Some information relates to prerelease product that may be substantially modified before its released. The evidence that first succeeds is the evidence that is used. In this case, the method doesn't allow you to indicate the load option, and uses the default, PreserveChanges. Loads an assembly given its AssemblyName. For this code example to run, you must provide the fully qualified assembly name. Microsoft makes no warranties, express or implied, with respect to the information provided here. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. To load an extension DLL, you can do one of the following: Use the .load or .loadby command. The assembly is loaded into the application domain of the caller using the specified source for the security context. Load columns as: Individual columns like Size and CurrentPrices in the HousingData class. 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. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. This applies to the .NET Framework version 1.1 Service Pack 1 (SP1) and subsequent releases. For example, to access a 2D texture, supply integer texel coordinates for the first two components and a mipmap level for the third component. 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 value of securityContextSource is not one of the enumeration values. Supplying a partial assembly name for assemblyRef is not recommended. 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. This file must be created in advance by using the. This operation is not supported on the current platform. Evidence of the calling assembly and evidence of the COFF image are ignored. 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. WebThis occurs because the form values have already been loaded. In this Microsoft makes no warranties, express or implied, with respect to the information provided here. Version 2.0 or later of the common language runtime is currently loaded and assemblyRef was compiled with a later version. 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. Updates the current and original versions of the row with the value of the incoming row. After this file is loaded successfully, I consider to use inside to load another screen from 'C:\SubScreens\Screen1.xaml'. Microsoft makes no warranties, express or implied, with respect to the information provided here. 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. 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. An assembly or module was loaded twice with two different evidences. Each of these tables must be a member of the DataTableCollection contained by this DataSet. 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 service simulates traffic for your applications, regardless of where they're hosted. 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. The Upsert option facilitates aggregating changes from one or more secondary data sources. Key scenarios that you can accomplish using Azure Standard 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. For other examples that might be available, see the individual overload topics. Incremental data feed from secondary data sources. The following example instantiates an AssemblyName object and uses it to load the sysglobal.dll assembly. The following example demonstrates several of the issues involved with calling the Load method. See . 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. For more information, see Reading XML Data using XPathDocument and XmlDocument. Execute an extension by issuing the full !DLLName.ExtensionCommand syntax. 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. Using partial names has a negative effect on performance. A FillErrorEventHandler delegate to call when an error occurs while loading data. A byte array that contains the raw bytes representing the symbols for the assembly. The TextReader used to feed the XML data into the document. The Load extension method works just like ToList except that it avoids the creation of the list altogether. 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. Azure Load Testing Preview is a fully managed load-testing service that enables you to generate high-scale load. Specifies the name and path of the file to be loaded. An assembly or module was loaded twice with two different evidences. 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. The raw bytes representing the symbols for the Assembly are also loaded. The offset type is dependent on the texture-object type, and needs to be static. 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). Have questions or feedback about Office VBA or this documentation? Shader Model 4.1 is available in Direct3D 10.1 or higher. A value from the LoadOption enumeration that indicates how rows already in the DataTable are combined with incoming rows that share the same primary key. The action may be applied to either the current or original version of each row, or both, depending on the current row state. Windows. Microsoft makes no warranties, express or implied, with respect to the information provided here. 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. The caller does not have the required permission. In the .NET Framework version 2.0, processor architecture is added to assembly identity, and can be specified as part of assembly name strings. (The overload that doesn't allow you to specify the behavior uses the default load option.) When converting data, the Load method uses the same conversion rules as the Fill method. Given these two hypothetical data sources, a user is likely to require one of the following behaviors: Initialize DataTable from a primary data source. The URL can be either a local file or an HTTP URL (a Web address). For more information, see Row States and Row Versions. Windows. Rather than trapping the error, this example uses a FillErrorEventHandler delegate to investigate and handle the error. 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 display name of the assembly. The assembly is loaded into the application domain of the caller. Writes saved subkeys and entries into a different subkey in the registry. The techniques shown in this topic apply equally to models created with Code First and the EF Designer. Returns It's important to note that all of the elements in the vector More info about Internet Explorer and Microsoft Edge, Load(IDataReader, LoadOption, DataTable[]), Load(IDataReader, LoadOption, FillErrorEventHandler, DataTable[]). This method allows you to specify a load option parameter, indicating how rows already in a DataTable combine with rows being loaded. Load columns as: Individual columns like Size and CurrentPrices in the HousingData class. The following example uses the StringReader class to load a string of XML data into the XmlDocument object. When you use a Load method with a Byte[] parameter and Evidence to load a COFF image, only the supplied evidence is used. An array of type byte that is a COFF-based image containing an emitted assembly. This command is intended for use with temporary files that are used for troubleshooting or editing registry entries. WebLoad (Stream) Creates a new XDocument instance by using the specified stream. C# Copy public static System.Xml.Linq.XDocument Load (System.IO.Stream stream); Parameters stream Stream The stream that contains the XML data. Microsoft makes no warranties, express or implied, with respect to the information provided here. The evidence that first succeeds is the evidence that is used. In this scenario, the user wants to initialize an empty DataTable with values from the primary data source. Use the Show method to make the object visible. The object can be manipulated programmatically in its Initialize event procedure. WebTo load the correct assembly, it's recommended to call the Load method by passing the long form of the assembly name. To 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. If the file is not found, CodeBase is used to search for the 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 DataTable). Windows. 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. ; If you have a vector property, apply the VectorType attribute to the property in your data model. This method is a Microsoft extension to the Document Object Model (DOM). If a remote computer is specified, valid root keys are: HKLM and HKU. 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. There is a set of screens provided and all are in .xaml extensions. A load balancer health probe monitors a given port on each VM and only distributes traffic to an operational VM. The name resolution scheme for this method is the same as that followed by the Fill method of the DbDataAdapter class. WebLoad (String) Load (Byte [], Byte []) Overloads Load (Byte []) Loads the Assembly with a common object file format (COFF) based image containing an emitted Assembly. Remarks When an object is loaded, it is placed in memory, but isn't visible. Loads an Assembly given its AssemblyName. The expression should return true to load and false to unload the element. The URL can be either a local file or an HTTP URL (a Web address). An Azure load balancer is a Layer-4 (TCP, UDP) load balancer that provides high availability by distributing incoming traffic among healthy VMs. 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. The Load method's overwrites the read-only column values, if needed. assemblyRef is not a valid assembly. 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. A DataSet synchronizes or updates with a single primary data source. These issues, and more, are controlled by the loadOption parameter. Please see Office VBA support and feedback for guidance about the ways you can receive support and provide feedback. How should the Load method handle loading rows that have the same primary key as existing rows? The following table displays behavior for the Load method. Developers, testers, and quality assurance (QA) engineers can use it to optimize application performance, scalability, or capacity. Some information relates to prerelease product that may be substantially modified before its released. A DataTable synchronizes or updates with a single 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 ). Let me explain it again. To enable execution of code loaded from remote locations, you can use the configuration element. For information about the disadvantages of using the load-from context, see the Assembly.LoadFrom method overload or Best Practices for Assembly Loading. Please use an overload of Load which does not take an Evidence parameter. If a matching table is found, that table is loaded with the content of the current result set. In this case, a FileNotFoundException is raised. 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.
