If you select the Upsert option, it is assumed that the data is coming from one of a secondary data source, such as data provided by a middle-tier component, perhaps altered by a user. Should it modify current values, original values, or both? Some information relates to prerelease product that may be substantially modified before its released. 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. Load object The object placeholder represents an object expression that evaluates to an object in the Applies To list. See the documentation for the DataTableLoad method for more information on using this parameter. 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. The expression should return true to load and false to unload the element. Call GetTemplateChild with the name that you defined on the element. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. 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. 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. 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 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. See AssemblyName.ProcessorArchitecture. 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 URL can be either a local file or an HTTP URL (a Web address). Finally, the example displays the contents of the tables in the console window. If the DataTable already contains rows, the incoming data from the data source is merged with the existing rows. FileLoadException is thrown if assemblyString specifies the full assembly name, and the first assembly that matches the simple name has a different version, culture, or public key token. 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. Incremental data feed from secondary data sources. Later the user intends to propagate changes back to the primary data source. The following example instantiates an AssemblyName object and uses it to load the sysglobal.dll assembly. In this Updates the current version of the row with the value of the incoming row. See . 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. Preserve changes and re-synchronize from the primary data source. The following example demonstrates several of the issues involved with calling the Load method. 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. The evidence that first succeeds is the evidence that is used. See http://go.microsoft.com/fwlink/?LinkID=155570 for more information. The example uses the file, books.xml, as input. This operation is not supported on the current platform. Parameters Object More info about Internet Explorer and Microsoft Edge, Load(IDataReader, LoadOption, FillErrorEventHandler). [in] A sampling index. If a remote computer is specified, valid root keys are: HKLM and HKU. After this file is loaded successfully, I consider to use inside to load another screen from 'C:\SubScreens\Screen1.xaml'. Loading Elements There are several different ways to load the elements: Use an x:Bind expression to specify the load state. Have questions or feedback about Office VBA or this documentation? The first is taken from a Windows Forms data binding application where Load is used to A byte array that is a COFF-based image containing an emitted assembly. Loads the XML document from the specified XmlReader. Microsoft makes no warranties, express or implied, with respect to the information provided here. See Row States and Row Versions for more information. Firstly, I want to load a Main Screen file from 'C:\MainScreen.xaml'. The first is taken from a Windows Forms data binding application where Load is used to 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. 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 Load method attempts to find a table within the DataSet matching the name found in the array of table names, in order. This version of the Load method attempts to preserve the current values in each row, leaving the original value intact. WebThe Load method provides a technique for filling a single DataTable with data, retrieved from an IDataReader instance. Load balancer supports both inbound and outbound scenarios. Occurs when the server control is loaded into the Page object. Direct3D guarantees to return zero for any resource that is accessed out of bounds. An object that describes the assembly to load. 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. assemblyRef is not a valid assembly. Call FindName with the name that you defined on the element. Execute an extension by issuing the full !DLLName.ExtensionCommand syntax. One common way to do this is to write a LINQ query and then call ToList on it, only to immediately discard the created list. Call FindName with the name that you defined on the element. The assembly is loaded into the domain of the caller using the supplied evidence. After this file is loaded successfully, I consider to use inside to load another screen from 'C:\SubScreens\Screen1.xaml'. Version 2.0 or later of the common language runtime is currently loaded and assemblyRef was compiled with a later version. 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. These scenarios describe standard usage for a DataTable, describing its update and merge behavior. For information that is common to all overloads of this method, see the Load(AssemblyName) method overload. You can access view state information and Web form POST data from this event. Load object The object placeholder represents an object expression that evaluates to an object in the Applies To list. 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. Instead, the common language runtime tries to load the assembly into the calling application domain. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Later the user intends to propagate changes back to the primary data source. See http://go.microsoft.com/fwlink/?LinkID=155570 for more information. Loads the assembly with a common object file format (COFF)-based image containing an emitted assembly, optionally including symbols for the assembly. The Load method fills each supplied DataTable instance with data from a single result set from the source data reader. ; Multiple columns at a time in the form of a vector like HistoricalPrices in the HousingData class. WebLoad (Stream) Creates a new XDocument instance by using the specified stream. The Load method makes all these scenarios possible. ; If you have a vector property, apply the VectorType attribute to the property in your data model. ; Multiple columns at a time in the form of a vector like HistoricalPrices in the HousingData class. Use the Show method to make the object visible. Version 2.0 or later of the common language runtime is currently loaded and assemblyString was compiled with a later version. C# public virtual void Load (string filename); Parameters filename String URL for the file containing the XML document to load. 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. The Load method makes all these scenarios possible. 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. Loads an assembly given its display name, loading the assembly into the domain of the caller using the supplied evidence. This method provides the same functionality, but allows you to load multiple result sets from an IDataReader into multiple tables within a DataSet. Loads the XML document from the specified URL. Here are two examples of using Load. Set the property to false to indicate that you wish to halt processing. The default namespace associated with DataSet, if any, is associated with each newly created DataTable. The XmlReader used to feed the XML data into the document. Some information relates to prerelease product that may be substantially modified before its released. In this For information about how to obtain the fully qualified assembly name, see Assembly Names. Returns XDocument An XDocument object that reads the data that is contained in the stream. The Load extension method works just like ToList except that it avoids the creation of the list altogether. 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 DataTable instances, from which the Load(IDataReader, LoadOption, DataTable[]) method retrieves name and namespace information. Loads the assembly with a common object file format (COFF)-based image containing an emitted assembly. WebThis occurs because the form values have already been loaded. More info about Internet Explorer and Microsoft Edge, http://go.microsoft.com/fwlink/?LinkID=155570, http://go.microsoft.com/fwlink/?LinkId=155570. The following table describes the three load options provided by the LoadOption enumeration. 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. This file must be created in advance by using the How should the Load method handle loading rows that have the same primary key as existing rows? Here are two examples of using Load. See the documentation for the Load method for more information on using this parameter. The DataTable tracks changes, allowing synchronization with the primary data source. The Load extension method works just like ToList except that it avoids the creation of the list altogether. The return type matches the type in the Object declaration. Here are two examples of using Load. Not supported for other textures. WebLoad (String) Loads the XML document from the specified URL. This method is obsolete and will be removed in a future release of the .NET Framework. 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. . There is a set of screens provided and all are in .xaml extensions. The value of securityContextSource is not one of the enumeration values. The example then displays the full name of the assembly's public types. An Azure load balancer is a Layer-4 (TCP, UDP) load balancer that provides high availability by distributing incoming traffic among healthy VMs. When an object is loaded, it is placed in memory, but isn't visible. 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. Some information relates to prerelease product that may be substantially modified before its released. 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 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. 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.) To specify a remote computer, include the computer name (in the format, Specifies the name and path of the file to be loaded. An array of type byte containing the raw bytes representing the symbols for the assembly. Reads texel data without any filtering or sampling. Subsequent clicking on UserForm2 reveals UserForm1. A FillErrorEventHandler delegate to call when an error occurs while loading data. Firstly, I want to load a Main Screen file from 'C:\MainScreen.xaml'. C# public virtual void Load (string filename); Parameters filename String URL for the file containing the XML document to load. 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. 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 ). Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Parameters Object More info about Internet Explorer and Microsoft Edge. 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. 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. 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. More info about Internet Explorer and Microsoft Edge, Load(Byte[], Byte[], SecurityContextSource), http://go.microsoft.com/fwlink/?LinkID=155570. Load columns as: Individual columns like Size and CurrentPrices in the HousingData class. . For more information, see Reading XML Data using XPathDocument and XmlDocument.

Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. WebLoad (String) Loads the XML document from the specified URL. For more information, see Row States and Row Versions. Loads the Assembly with a common object file format (COFF) based image containing an emitted Assembly. There is a load or parse error in the XML. URL for the file containing the XML document to load. The Load method always preserves significant white space. An array of type byte that is a COFF-based image containing an emitted assembly. To load an extension DLL, you can do one of the following: Use the .load or .loadby command. 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. The first is taken from a Windows Forms data binding application where Load is used to Fills a DataTable with values from a data source using the supplied IDataReader. Rather than trapping the error, this example uses a FillErrorEventHandler delegate to investigate and handle the error. In this An assembly or module was loaded twice with two different evidences. The document begins loading at this point. Supplying a partial assembly name for assemblyRef is not recommended. Call GetTemplateChild with the name that you defined on the element. If a remote computer is specified, valid root keys are: HKLM and HKU. 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. Loads the XML document from the specified stream. WebLoad (String) Load (Byte [], Byte []) Overloads Load (Byte []) Loads the Assembly with a common object file format (COFF) based image containing an emitted Assembly. ; If you have a vector property, apply the VectorType attribute to the property in your data model. Some information relates to prerelease product that may be substantially modified before its released. Next steps. Please use an overload of Load which does not take an Evidence parameter. Load balancing aims to optimize resource use, maximize throughput, minimize response time, and avoid overloading any single resource. 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. 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 stream containing the XML document to load. Updates the original version of the row with the value of the incoming row. The caller does not have the required permission. The DataSet isn't responsible for tracking changes in order to allow synchronization with the secondary data source. The assembly is loaded into the application domain of the caller. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. These values may be equivalent, or may be different if the data in the row has been changed since filling the DataTable. Reflecting on C++ executable files might throw a BadImageFormatException. Version 2.0 or later of the common language runtime is currently loaded and rawAssembly was compiled with a later version.
