Version 2.0 or later of the common language runtime is currently loaded and assemblyString was compiled with a later version. If the registry key name contains a space, enclose the key name in quotes. This file must be created in advance by using the 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. Firstly, I want to load a Main Screen file from 'C:\MainScreen.xaml'. Loads the XML document from the specified stream. There is a set of screens provided and all are in .xaml extensions. Remarks When an object is loaded, it is placed in memory, but isn't visible. The default is false; white space in element content is not preserved. C# Copy public static System.Xml.Linq.XDocument Load (System.IO.Stream stream); Parameters stream Stream The stream that contains the XML data. Fills a DataTable with values from a data source using the supplied IDataReader using an error-handling delegate. When you use a Load method with a Byte[] parameter and Evidence to load a COFF image, only the supplied evidence is used. Use the Show method to make the object visible. To enable execution of code loaded from remote locations, you can use the configuration element. 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. Developers, testers, and quality assurance (QA) engineers can use it to optimize application performance, scalability, or capacity. rawAssembly was compiled with a later version of the common language runtime than the version that is currently loaded. 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. 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. After this file is loaded successfully, I consider to use inside to load another screen from 'C:\SubScreens\Screen1.xaml'. The Load method handles such columns in a manner that is consistent with the behavior defined by the column's properties. The Load method attempts to find a table within the DataSet matching the name found in the array of table names, in order. This action value varies, depending on the state of the row before the load operation. WebLoad-balancing options. Updates the original version of the row with the value of the incoming row. The example then focuses on data issues, including handling the various loading options. 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 ). 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. If you need to use a XmlDocument object to work with XML, you can use the XmlTextReader object to create one. 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 this A good example of this is loading entities for data binding as described in Local Data. Until an object is visible, a user can't interact with it. 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. Load balancing aims to optimize resource use, maximize throughput, minimize response time, and avoid overloading any single resource. 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. filename specified a file that is read-only. Loads an Assembly given its AssemblyName. The assembly is loaded into the application domain of the caller. Forms Assembly: System.Windows.Forms.dll Important Some information relates to prerelease product that may be substantially modified before its released. C# Copy public static System.Xml.Linq.XDocument Load (System.IO.Stream stream); Parameters stream Stream The stream that contains the XML data. WebLoad (Stream) Creates a new XDocument instance by using the specified stream. After this file is loaded successfully, I consider to use inside to load another screen from 'C:\SubScreens\Screen1.xaml'. 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 term load balancing refers to the distribution of workloads across multiple computing resources. The long or short form of the assembly name. More info about Internet Explorer and Microsoft Edge, Introduction to the ASP.NET Page Life Cycle. In each case, both events occur, and the action is the same for each. More info about Internet Explorer and Microsoft Edge, http://go.microsoft.com/fwlink/?LinkID=155570, http://go.microsoft.com/fwlink/?LinkId=155570. C# public virtual void Load (string filename); Parameters filename String URL for the file containing the XML document to load. 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. Execute an extension by issuing the full !DLLName.ExtensionCommand syntax. A byte array that contains the raw bytes representing the symbols for the assembly. The techniques shown in this topic apply equally to models created with Code First and the EF Designer. WebThe Load method provides a technique for filling a single DataTable with data, retrieved from an IDataReader instance. A FillErrorEventHandler delegate to call when an error occurs while loading data. See http://go.microsoft.com/fwlink/?LinkId=155570 for more information. 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. 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. This method should be used only to load an assembly into the current application domain. For information about the disadvantages of using the load-from context, see the Assembly.LoadFrom method overload or Best Practices for Assembly Loading. These values may be equivalent, or may be different if the data in the row has been changed since filling the DataTable. 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. 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. Should it modify current values, original values, or both? The value of securityContextSource is not one of the enumeration values. Rather than trapping the error, this example uses a FillErrorEventHandler delegate to investigate and handle the error. The Load extension method works just like ToList except that it avoids the creation of the list altogether. WebLoad (String) Load (Byte [], Byte []) Overloads Load (Byte []) Loads the Assembly with a common object file format (COFF) based image containing an emitted Assembly. Note that this method overload always creates a new Assembly object with its own mapping. For information that is common to all overloads of this method, see the Load(AssemblyName) method overload. 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). The following example demonstrates how to use the SetDesktopLocation, Load, Activated, and Activate members. These scenarios describe standard usage for a DataTable, describing its update and merge behavior. Loads an Assembly given its display name. Subsequent clicking on UserForm2 reveals UserForm1. See Row States and Row Versions for more information. 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 following example instantiates an AssemblyName object and uses it to load the sysglobal.dll assembly. 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 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. Not supported for other textures. This file must be created in advance by using the. Loads the assembly with a common object file format (COFF)-based image containing an emitted assembly, optionally including symbols for the assembly. 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. For information about how to obtain the fully qualified assembly name, see Assembly Names. Until an object is visible, a user can't interact with it. The load operation will fail with an InvalidOperationException if any of the source data columns in the incoming reader are computed columns. Updates the current version of the row with the value of the incoming row. The URL can be either a local file or an HTTP URL (a Web address). Loads an assembly given its AssemblyName. The service simulates traffic for your applications, regardless of where they're hosted. Exceptions XmlException There is a load or parse error in the XML. Fills a DataSet with values from a data source using the supplied IDataReader. 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. This method provides the same functionality, but allows you to load multiple result sets from an IDataReader into multiple tables within a DataSet. See http://go.microsoft.com/fwlink/?LinkID=155570 for more information. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. For example, a Texture2D object that was declared as "Texture2d myTexture;" has a return value of type uint4. For other examples that might be available, see the individual overload topics. SampleIndex must always be specified first with multi-sample textures. 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. Developers, testers, and quality assurance (QA) engineers can use it to optimize application performance, scalability, or capacity. Once the data has been loaded, the example displays the contents of all its tables in the Console window. 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. An Azure load balancer is a Layer-4 (TCP, UDP) load balancer that provides high availability by distributing incoming traffic among healthy VMs. 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. If the DataTable already contains rows, the incoming data from the data source is merged with the existing rows according to the value of the loadOption parameter. To load an extension DLL, you can do one of the following: Use the .load or .loadby command. The URL can be either a local file or an HTTP URL (a Web address). The assemblies that are loaded into the two application domains might be different if the path settings for the two application domains are different. When converting data, the Load method uses the same conversion rules as the Fill method. 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. Applies to See also Introduction to the ASP.NET Page Life Cycle Recommended content UpdatePanel (System.Web.UI) LinkButton (System.Web.UI.WebControls) Web 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. Windows. To load assemblies into other application domains, use a method such as CreateInstanceAndUnwrap. See . typeX denotes that there are four possible types: int, int2, int3 or int4. If a version of the requested assembly is already loaded, this method returns the loaded assembly, even if a different version is requested. After each result set, the Load method moves on to the next result set within the reader, until there are no more result sets. 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. [in] The texture coordinates; the last component specifies the mipmap level. The object that describes the assembly to be loaded. The techniques shown in this topic apply equally to models created with Code First and the EF Designer. A load balancer health probe monitors a given port on each VM and only distributes traffic to an operational VM. This is most likely caused by the C++ compiler stripping the relocation addresses or the .reloc section from your executable file. This method is obsolete and will be removed in a future release of the .NET Framework. An array of type byte that is a COFF-based image containing an emitted assembly. The display name of the assembly. Loads the Assembly with a common object file format (COFF) based image containing an emitted Assembly. 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". Given these two hypothetical data sources, a user is likely to require one of the following behaviors: Initialize DataSet from a primary data source. Remarks 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. 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 DataSet). Returns An Azure load balancer is a Layer-4 (TCP, UDP) load balancer that provides high availability by distributing incoming traffic among healthy VMs. The DataSet tracks changes, allowing synchronization with the primary data source. ; If you have a vector property, apply the VectorType attribute to the property in your data model. Occurs when the server control is loaded into the Page object. If you set a custom template in a control during the Page_Load event, the text values of child controls in the custom template will be lost. Some information relates to prerelease product that may be substantially modified before its released. If a remote computer is specified, valid root keys are: HKLM and HKU. Let me explain it again. (A partial name omits one or more of culture, version, or public key token. Incremental data feed from secondary data sources. Load object The object placeholder represents an object expression that evaluates to an object in the Applies To list. With Azure Load Balancer, you can scale your applications and create highly available services. In the .NET Framework version 2.0, processor architecture is added to assembly identity, and can be specified as part of assembly name strings. Execute an extension by issuing the full !DLLName.ExtensionCommand syntax. The XmlReader used to feed the XML data into the document. For more information about handling events, see Handling and Raising Events. 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. (If you want finer control over the behavior of incoming data, see DataTable.Load.) ; If you have a vector property, apply the VectorType attribute to the property in your data model. The URL can be either a local file or an HTTP URL (a Web address). Loads an assembly given its AssemblyName. To specify a remote computer, include the computer name (in the format, Specifies the name and path of the file to be loaded. If the assembly is found using CodeBase, the display name is matched against the assembly. You can access view state information and Web form POST data from this event. Using partial names has a negative effect on performance. See the documentation for the DataTableLoad method for more information on using this parameter. Azure Load Testing Preview is a fully managed load-testing service that enables you to generate high-scale load. The file specified in filename was not found. The following example demonstrates several of the issues involved with calling the Load method. Values in a DataColumn can be constrained through use of properties such as ReadOnly and AutoIncrement. These scenarios describe standard usage for a DataTable, describing its update and merge behavior. Direct3D guarantees to return zero for any resource that is accessed out of bounds. The Upsert option facilitates aggregating changes from one or more secondary data sources. Each cell in this table describes the current and original value for a field within a row, along with the DataRowState for the value after the Load method has completed. Instead, the assembly is loaded using load-from rules. The errorHandler parameter is a FillErrorEventHandler delegate that refers to a procedure that is called when an error occurs while loading data. If the match fails, a FileLoadException is thrown. WebLoad (String) Loads the XML document from the specified URL. . The first is taken from a Windows Forms data binding application where Load is used to 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. This applies to the .NET Framework version 1.1 Service Pack 1 (SP1) and subsequent releases. WebLoad (Stream) Creates a new XDocument instance by using the specified stream. Execute an extension by issuing the full !DLLName.ExtensionCommand syntax. Specifies the name and path of the file to be loaded. When you use a Load method overload with a Byte[] parameter to load a COFF image, evidence is inherited from the calling assembly. 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. For example, "ProcessorArchitecture=msil". More info about Internet Explorer and Microsoft Edge, Load(IDataReader, LoadOption, DataTable[]), Load(IDataReader, LoadOption, FillErrorEventHandler, DataTable[]). There is a set of screens provided and all are in .xaml extensions. Loading Elements There are several different ways to load the elements: Use an x:Bind expression to specify the load state. An array of strings, from which the Load method retrieves table name information. The term load balancing refers to the distribution of workloads across multiple computing resources. Loads the XML document from the specified URL. Writes saved subkeys and entries into a different subkey in the registry. 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.
