An IDataReader that provides one or more result sets. Load balancing aims to optimize resource use, maximize throughput, minimize response time, and avoid overloading any single resource. Remarks The expression should return true to load and false to unload the element. 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 ). Loads an assembly given its display name, loading the assembly into the domain of the caller using the supplied evidence. More info about Internet Explorer and Microsoft Edge. The following example demonstrates several of the issues involved with calling the Load method. The first is taken from a Windows Forms data binding application where Load is used to query for entities before binding to the local collection, as described in Local Data: The second example shows using Load to load a filtered collection of related entities, as described in Loading Related Entities: More info about Internet Explorer and Microsoft Edge. Call FindName with the name that you defined on the element. In this scenario, the user wants to initialize an empty DataSet with values from the primary data source. The DataTable tracks changes, allowing synchronization with the primary data source. For information about the disadvantages of using the load-from context, see the Assembly.LoadFrom method overload or Best Practices for Assembly Loading. Each of these tables must be a member of the DataTableCollection contained by this DataSet. See Row States and Row Versions for more information. Returns Call GetTemplateChild with the name that you defined on the element. The Load extension method works just like ToList except that it avoids the creation of the list altogether. This method provides the same functionality, but allows you to load multiple result sets from an IDataReader into multiple tables within a DataSet. An Azure load balancer is a Layer-4 (TCP, UDP) load balancer that provides high availability by distributing incoming traffic among healthy VMs. assemblyRef is not a valid assembly. The expression should return true to load and false to unload the element. Remarks When an object is loaded, it is placed in memory, but isn't visible. If the registry key name contains a space, enclose the key name in quotes. . The service simulates traffic for your applications, regardless of where they're hosted. After this file is loaded successfully, I consider to use inside to load another screen from 'C:\SubScreens\Screen1.xaml'. 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. Loads the specified XML data from a Stream, a URL, a TextReader, or an XmlReader. The document begins loading at this point. Please use an overload of Load which does not take an Evidence parameter. Some information relates to prerelease product that may be substantially modified before its released. In addition, a DataTable can accept incremental data from one or more secondary data sources. The DataTable isn't responsible for tracking changes in order to allow synchronization with the secondary data source. An assembly or module was loaded twice with two different evidences. URL for the file containing the XML document to load. The default is false; white space in element content is not preserved. 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. Microsoft makes no warranties, express or implied, with respect to the information provided here. When working with the schema, the Load method may encounter conditions as described in the following table. The following example uses the StringReader class to load a string of XML data into the XmlDocument object. See FullName. Execute an extension by issuing the full !DLLName.ExtensionCommand syntax. Some information relates to prerelease product that may be substantially modified before its released. The Load method's overwrites the read-only column values, if needed. 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. Load balancer supports both inbound and outbound scenarios. assemblyRef specifies a remote assembly, but the ability to execute code in remote assemblies is disabled. C# Copy public static System.Xml.Linq.XDocument Load (System.IO.Stream stream); Parameters stream Stream The stream that contains the XML data. To load an extension DLL, you can do one of the following: Use the .load or .loadby command. 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). An assembly or module was loaded twice with two different evidences. Please see Office VBA support and feedback for guidance about the ways you can receive support and provide feedback. Updates the current and original versions of the row with the value of the incoming row. 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 reader is in the initial state (ReadState =ReadState.Initial), Load consumes the entire contents of the reader and builds the DOM from what it finds. 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. More info about Internet Explorer and Microsoft Edge. The URL can be either a local file or an HTTP URL (a Web address). 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). C# public virtual void Load (string filename); Parameters filename String URL for the file containing the XML document to load. The caller does not have the required permission. Loading Elements There are several different ways to load the elements: Use an x:Bind expression to specify the load state. See http://go.microsoft.com/fwlink/?LinkID=155570 for more information. Load object The object placeholder represents an object expression that evaluates to an object in the Applies To list. When converting data, the Load method uses the same conversion rules as the DbDataAdapter.Fill method. 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. In each case, both events occur, and the action is the same for each. Fills a DataTable with values from a data source using the supplied IDataReader. 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. The example then focuses on data issues, including handling the various loading options. The assembly is loaded into the domain of the caller using the supplied evidence. When converting data, the Load method uses the same conversion rules as the Fill method. In this scenario, the user wants to initialize an empty DataTable with values from the primary data source. The specified path, file name, or both exceed the system-defined maximum length. In each case, both events occur, and the action is the same for each. These scenarios describe standard usage for a DataTable, describing its update and merge behavior. The Load method always preserves significant white space. Remarks WebTo load the correct assembly, it's recommended to call the Load method by passing the long form of the assembly name. 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. This operation is not supported on the current platform. There is a set of screens provided and all are in .xaml extensions. Direct3D guarantees to return zero for any resource that is accessed out of bounds. -or-. Remarks When an object is loaded, it is placed in memory, but isn't visible. The Load method attempts to find a table within the DataSet matching the name found in the array of table names, in order. The following table describes the three load options provided by the LoadOption enumeration. [in] An optional offset applied to the texture coordinates before sampling. This partial code example is from the Paint.fx file in the AdvancedParticles Sample. Loads the assembly with a common object file format (COFF)-based image containing an emitted assembly. There are several scenarios where you may want to load entities from the database into the context without immediately doing anything with those entities. Use the Show method to make the object visible. Firstly, I want to load a Main Screen file from 'C:\MainScreen.xaml'. The assembly is loaded into the domain of the caller using the supplied evidence. 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. Loads the assembly with a common object file format (COFF)-based image containing an emitted assembly, optionally including symbols and evidence for the assembly. Loads the XML document from the specified stream. Here are two examples of using Load. typeX denotes that there are four possible types: int, int2, int3 or int4. Key scenarios that you can accomplish using Azure Standard C# public virtual void Load (string filename); Parameters filename String URL for the file containing the XML document to load. ; Multiple columns at a time in the form of a vector like HistoricalPrices in the HousingData class. Loads the XML document from the specified TextReader. This file is in format. The loader does not continue probing for other assemblies that match the simple name. The Load method handles such columns in a manner that is consistent with the behavior defined by the column's properties. Here are two examples of using Load. The load operation will fail with an InvalidOperationException if any of the source data columns in the incoming reader are computed columns. Load balancer provides low latency and high throughput, and scales up to millions of flows for all TCP and UDP applications. Given these two hypothetical data sources, a user is likely to require one of the following behaviors: Initialize DataSet from a primary data source. 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). 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. 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. Here are two examples of using Load. Not supported for other textures. The assembly is loaded into the application domain of the caller using the specified source for the security context. 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. In this method call, the specified LoadOption parameter influences the processing of the incoming data. C# Copy public static System.Xml.Linq.XDocument Load (System.IO.Stream stream); Parameters stream Stream The stream that contains the XML data. 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. If a remote computer is specified, valid root keys are: HKLM and HKU. The following example loads an assembly given its fully qualified name, and lists all the types contained in the specified assembly. Some information relates to prerelease product that may be substantially modified before its released. There is a load or parse error in the XML. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. 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. Version 2.0 or later of the common language runtime is currently loaded and rawAssembly was compiled with a later version. 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 TextReader used to feed the XML data into the document. Later the user intends to propagate changes back to the primary data source. An Azure load balancer is a Layer-4 (TCP, UDP) load balancer that provides high availability by distributing incoming traffic among healthy VMs. More info about Internet Explorer and Microsoft Edge, Reading XML Data using XPathDocument and XmlDocument. WebLoad Event Reference Feedback Definition Namespace: System. Version 2.0 or later of the common language runtime is currently loaded and assemblyString was compiled with a later version. Load balancer supports both inbound and outbound scenarios. 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 ). Do not use an AssemblyName with only the CodeBase property set. The name resolution scheme for this method is the same as that followed by the Fill method of the DbDataAdapter class. WebTo load the correct assembly, it's recommended to call the Load method by passing the long form of the assembly name. One or more DataTable's contents are modified. This file is in format. This method allows you to specify a load option parameter, indicating how rows already in a DataTable combine with rows being loaded. Loads an assembly given its AssemblyName. Occurs before a form is displayed for the first time. The assemblies that are loaded into the two application domains might be different if the path settings for the two application domains are different. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. To load assemblies into other application domains, use a method such as CreateInstanceAndUnwrap. To enable execution of code loaded from remote locations, you can use the configuration element. The XmlReader used to feed the XML data into the document. If the current AppDomain object represents application domain A, and the Load method is called from application domain B, the assembly is loaded into both application domains. This is most likely caused by the C++ compiler stripping the relocation addresses or the .reloc section from your executable file. The expression should return true to load and false to unload the element. 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). For information that is common to all overloads of this method, see the Load(AssemblyName) method overload. Loads an assembly given its AssemblyName. You can access view state information and Web form POST data from this event. If you want validation to occur, you can create a validating XmlReader instance by using the XmlReaderSettings class and the Create method. 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. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. 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. Supplying a partial assembly name for assemblyRef is not recommended. The term load balancing refers to the distribution of workloads across multiple computing resources. The object placeholder represents an object expression that evaluates to an object in the Applies To list. The term load balancing refers to the distribution of workloads across multiple computing resources. Returns XDocument An XDocument object that reads the data that is contained in the stream. 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. The DataSet isn't responsible for tracking changes in order to allow synchronization with the secondary data source. [in] A sampling index. Values in a DataColumn can be constrained through use of properties such as ReadOnly and AutoIncrement. Azure Load Testing Preview is a fully managed load-testing service that enables you to generate high-scale load. securityEvidence is not null. The object that describes the assembly to be loaded. Incremental data feed from secondary data sources. Until an object is visible, a user can't interact with it. 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. 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. To load an extension DLL, you can do one of the following: Use the .load or .loadby command. Let me explain it again. 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. Required for multi-sample textures. The operation is attempted on an unloaded application domain. If a remote computer is specified, valid root keys are: HKLM and HKU. WebThe Load method provides a technique for filling a single DataTable with data, retrieved from an IDataReader instance. This file must be created in advance by using the 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. An array of strings, from which the Load method retrieves table name information. The service simulates traffic for your applications, regardless of where they're hosted.
