The first is taken from a Windows Forms data binding application where Load is used to 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. If a remote computer is specified, valid root keys are: HKLM and HKU. The following example loads the last book node of the books.xml file into the XML document. ; If you have a vector property, apply the VectorType attribute to the property in your data model. This file is in format. Developers, testers, and quality assurance (QA) engineers can use it to optimize application performance, scalability, or capacity. In addition, a DataSet can accept incremental data from one or more secondary data sources. Loading Elements There are several different ways to load the elements: Use an x:Bind expression to specify the load state. The techniques shown in this topic apply equally to models created with Code First and the EF Designer. The assembly is loaded into the domain of the caller using the supplied evidence. Windows. 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 ). This method uses a 0-based coordinate system and not a 0.0-1.0 UV system. Using partial names has a negative effect on performance. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. 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.) 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. 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). Call FindName with the name that you defined on the element. 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. Returns XDocument An XDocument object that reads the data that is contained in the stream. The PreserveWhitespace property determines whether or not insignificant white space, that is white space in element content, is preserved. These scenarios describe standard usage for a DataTable, describing its update and merge behavior. The schema operations take place for all imported result sets, even those containing no data. In each case, both events occur, and the action is the same for each. When you use a Load method with a Byte[] parameter and Evidence to load a COFF image, only the supplied evidence is used. assemblyRef is not a valid assembly. A IDataReader that provides a result set. The service simulates traffic for your applications, regardless of where they're hosted. Values in a DataColumn can be constrained through use of properties such as ReadOnly and AutoIncrement. In this 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. The DataTable tracks changes, allowing synchronization with the primary data source. This method is provided as a convenience for interoperability callers who cannot call the static Assembly.Load method. The following Console application example first creates tables and loads data from a reader into a DataSet, using the Load method. Returns XDocument An XDocument object that reads the data that is contained in the stream. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. The Load extension method works just like ToList except that it avoids the creation of the list altogether. (The overload that doesn't allow you to specify the behavior uses the default load option.) The read only constraint on a DataColumn is applicable only for changes that occur in memory. Evidence of the calling assembly and evidence of the COFF image is ignored. The Load method consumes the first result set from the loaded IDataReader, and after successful completion, sets the reader's position to the next result set, if any. Fills a DataTable with values from a data source using the supplied IDataReader. Fills a DataSet with values from a data source using the supplied IDataReader, using an array of DataTable instances to supply the schema and namespace information. Load balancer provides low latency and high throughput, and scales up to millions of flows for all TCP and UDP applications. There is a set of screens provided and all are in .xaml extensions. 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 URL can be either a local file or an HTTP URL (a Web address). Execute an extension by issuing the full !DLLName.ExtensionCommand syntax. Remarks When an object is loaded, it is placed in memory, but isn't visible. More info about Internet Explorer and Microsoft Edge, Load(IDataReader, LoadOption, FillErrorEventHandler). 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. An assembly or module was loaded twice with two different evidences. Parameters Object Some information relates to prerelease product that may be substantially modified before its released. Version 2.0 or later of the common language runtime is currently loaded and assemblyString was compiled with a later version. Remarks Occurs when the server control is loaded into the Page object. Specifies the name and path of the file to be loaded. Key scenarios that you can accomplish using Azure Standard Reflecting on C++ executable files might throw a BadImageFormatException. If the assembly is found using CodeBase, the display name is matched against the assembly. 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. An array of DataTable instances, from which the Load(IDataReader, LoadOption, DataTable[]) method retrieves name and namespace information. 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. assemblyRef specifies a remote assembly, but the ability to execute code in remote assemblies is disabled. 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. The following table displays behavior for the Load method. Applies to See also Introduction to the ASP.NET Page Life Cycle Recommended content UpdatePanel (System.Web.UI) LinkButton (System.Web.UI.WebControls) Web To enable execution of code loaded from remote locations, you can use the configuration element. The Load extension method works just like ToList except that it avoids the creation of the list altogether. Load balancing aims to optimize resource use, maximize throughput, minimize response time, and avoid overloading any single resource. 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. 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. The name resolution scheme for this method is the same as that followed by the Fill method of the DbDataAdapter class. The object placeholder represents an object expression that evaluates to an object in the Applies To list. WebLoad (String) Loads the XML document from the specified URL. Supplying a partial assembly name for assemblyRef is not recommended. 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. These issues, and more, are controlled by the loadOption parameter. In this 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. In this scenario, the user wants to initialize an empty DataSet with values from the primary data source. More info about Internet Explorer and Microsoft Edge, Texture1DArray, Texture2D, Texture2DMSArray, Texture1D, Texture1DArray, Texture2D, Texture2DArray, Texture3D, Texture2DArray, TextureCube, TextureCubeArray, Texture2D, Texture2DArray, Texture2DMS, Texture2DMSArray. Each of these tables must be a member of the DataTableCollection contained by this DataSet. For this code example to run, you must provide the fully qualified assembly name. The Load method makes all these scenarios possible. C# public virtual void Load (string filename); Parameters filename String URL for the file containing the XML document to load. The default is false; white space in element content is not preserved. The techniques shown in this topic apply equally to models created with Code First and the EF Designer. 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. Later the user intends to propagate changes back to the primary data source. Let me explain it again. 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 XmlReader used to feed the XML data into the document. The load operation will fail with an InvalidOperationException if any of the source data columns in the incoming reader are computed columns. To load an assembly from a byte array with the trust level of the application domain, use the Load(Byte[], Byte[], SecurityContextSource) method overload. Loading Elements There are several different ways to load the elements: Use an x:Bind expression to specify the load state. Loads the XML document from the specified TextReader. This function is supported in the following shader models. For information that is common to all overloads of this method, see the Load(AssemblyName) method overload. In this Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Applies to See also Introduction to the ASP.NET Page Life Cycle Recommended content UpdatePanel (System.Web.UI) LinkButton (System.Web.UI.WebControls) Web The output is displayed in the console window. Returns XDocument An XDocument object that reads the data that is contained in the stream. Not supported for other textures. An array of type byte containing the raw bytes representing the symbols for the assembly. Loads the Assembly with a common object file format (COFF) based image containing an emitted Assembly. Microsoft makes no warranties, express or implied, with respect to the information provided here. Firstly, I want to load a Main Screen file from 'C:\MainScreen.xaml'. Developers, testers, and quality assurance (QA) engineers can use it to optimize application performance, scalability, or capacity. In this case, the method doesn't allow you to indicate the load option, and uses the default, PreserveChanges. Some information relates to prerelease product that may be substantially modified before its released. Starting with .NET Framework 4, because execution of code in remote assemblies is disabled by default, a FileLoadException is also thrown if assemblyRef specifies a remote assembly. 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. Zone, Url and Site are inherited from the calling assembly, and Hash and StrongName are taken from the COFF assembly. If you want validation to occur, you can create a validating XmlReader instance by using the XmlReaderSettings class and the Create method. 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. If the file is not found, CodeBase is used to search for the assembly. For example, a Texture2D object that was declared as "Texture2d myTexture;" has a return value of type uint4. Microsoft makes no warranties, express or implied, with respect to the information provided here. 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. 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). Load balancer supports both inbound and outbound scenarios. Updates the current version of the row with the value of the incoming row. See . Once the data has been loaded, the example displays the contents of all its tables in the Console window. This file must be created in advance by using the 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. After each result set, the Load method moves on to the next result set within the reader, until there are no more result sets. 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. Loads the XML document from the specified URL. For information about the disadvantages of using the load-from context, see the Assembly.LoadFrom method overload or Best Practices for Assembly Loading. The name resolution scheme for this method is the same as that followed by the Fill method of the DbDataAdapter class. The example then displays the full name of the assembly's public types. The CodeBase property does not supply any elements of the assembly identity (such as name or version), so loading does not occur according to load-by-identity rules, as you would expect from the Load method. The TextReader used to feed the XML data into the document. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Please see Office VBA support and feedback for guidance about the ways you can receive support and provide feedback. In addition, a DataTable can accept incremental data from one or more secondary data sources. After this file is loaded successfully, I consider to use inside to load another screen from 'C:\SubScreens\Screen1.xaml'. Some information relates to prerelease product that may be substantially modified before its released. If the registry key name contains a space, enclose the key name in quotes. In this case, the assumption is that the intent is to aggregate data from one or more data sources in the DataTable, and then perhaps propagate the data back to the primary data source. Loads the XML document from the specified stream. If the current node and its siblings look like the following: Load throws an exception because a document cannot have two root level elements. 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 display name of the assembly. Loads the specified XML data from a Stream, a URL, a TextReader, or an XmlReader. An IDataReader that provides one or more result sets. The Upsert option facilitates aggregating changes from one or more secondary data sources. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. The following example instantiates an AssemblyName object and uses it to load the sysglobal.dll assembly. A file that was found could not be loaded. Exceptions XmlException There is a load or parse error in the XML. In this scenario, the user wants to initialize an empty DataTable with values from the primary data source. The term load balancing refers to the distribution of workloads across multiple computing resources. Some information relates to prerelease product that may be substantially modified before its released. Load balancer supports both inbound and outbound scenarios. 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 Load extension method works just like ToList except that it avoids the creation of the list altogether. 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. WebThis occurs because the form values have already been loaded. See FullName. An I/O error occurred while opening the file. The default namespace associated with DataSet, if any, is associated with each newly created DataTable. 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. The Load method always preserves significant white space. ; Multiple columns at a time in the form of a vector like HistoricalPrices in the HousingData class. Pieces of evidence supplied as an argument to the Load method supersede pieces of evidence supplied by the loader. Use the Show method to make the object visible. Key scenarios that you can accomplish using Azure Standard 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). A texture-object type (except TextureCube or TextureCubeArray). An Azure load balancer is a Layer-4 (TCP, UDP) load balancer that provides high availability by distributing incoming traffic among healthy VMs. The following table describes the three load options provided by the LoadOption enumeration.
