WebTo load the correct assembly, it's recommended to call the Load method by passing the long form of the assembly name. In this This file is in format. Loads an Assembly given its display name. Windows. The URL can be either a local file or an HTTP URL (a Web address). The techniques shown in this topic apply equally to models created with Code First and the EF Designer. When you use a Load method with a Byte[] parameter and Evidence to load a COFF image, only the supplied evidence is used. A file that was found could not be loaded. Microsoft makes no warranties, express or implied, with respect to the information provided here. 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. Finally, the example displays the contents of the tables in the console window. The LoadOption parameter is used for determining the specific version of the row that is to be used for primary key comparison. This method is obsolete and will be removed in a future release of the .NET Framework. This partial code example is from the Paint.fx file in the AdvancedParticles Sample. Subsequent clicking on UserForm2 reveals UserForm1. Until an object is visible, a user can't interact with it. 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. Pieces of evidence supplied as an argument to the Load method supersede pieces of evidence supplied by the loader. Using partial names has a negative effect on performance. Returns XDocument An XDocument object that reads the data that is contained in the stream. C# public virtual void Load (string filename); Parameters filename String URL for the file containing the XML document to load. This method provides the same functionality, but allows you to load multiple result sets from an IDataReader into multiple tables within a DataSet. This method uses a 0-based coordinate system and not a 0.0-1.0 UV system. Should it modify current values, original values, or both? Before you save the document, you must add a root level element, otherwise Save will throw an exception. See . The URL can be either a local file or an HTTP URL (a Web address). 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. The action may be applied to either the current or original version of each row, or both, depending on the current row state. If a version of the requested assembly is already loaded, this method returns the loaded assembly, even if a different version is requested. 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. Loads the specified XML data from a Stream, a URL, a TextReader, or an XmlReader. In this method call, the specified LoadOption parameter influences the processing of the incoming data. These values may be equivalent, or may be different if the data in the row has been changed since filling the DataTable. WebLoad (Stream) Creates a new XDocument instance by using the specified stream. The loader does not continue probing for other assemblies that match the simple name. It's important to note that all of the elements in the vector This file is in format. 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. 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). Firstly, I want to load a Main Screen file from 'C:\MainScreen.xaml'. Some information relates to prerelease product that may be substantially modified before its released. C# public virtual void Load (string filename); Parameters filename String URL for the file containing the XML document to load. After each result set, the Load method moves on to the next result set within the reader, until there are no more result sets. Forms Assembly: System.Windows.Forms.dll Important Some information relates to prerelease product that may be substantially modified before its released. The output is displayed in the console window. [in] A sampling index. Loads the XML document from the specified stream. Loads the assembly with a common object file format (COFF)-based image containing an emitted assembly. Loads the Assembly with a common object file format (COFF) based image containing an emitted Assembly. The example then displays the full name of the assembly's public types. The document begins loading at this point. When an object is loaded, it is placed in memory, but isn't visible. 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 terms of event operations, the RowChanging event occurs before each row is changed, and the RowChanged event occurs after each row has been changed. In this case, a FileNotFoundException is raised. More info about Internet Explorer and Microsoft Edge, Load(IDataReader, LoadOption, FillErrorEventHandler). Remarks When an object is loaded, it is placed in memory, but isn't visible. The errorHandler parameter is a FillErrorEventHandler delegate that refers to a procedure that is called when an error occurs while loading data. There is a set of screens provided and all are in .xaml extensions. There is a load or parse error in the XML. Call GetTemplateChild with the name that you defined on the element. 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. A FillErrorEventHandler delegate to call when an error occurs while loading data. Be aware that setting the property to false causes the code that triggered the problem to throw an exception. Here are two examples of using Load. More info about Internet Explorer and Microsoft Edge. Fills a DataSet with values from a data source using the supplied IDataReader, using an array of strings to supply the names for the tables within the DataSet. The loader does not continue probing for other assemblies that match the simple name. Instead, the common language runtime tries to load the assembly into the calling application domain. 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 techniques shown in this topic apply equally to models created with Code First and the EF Designer. 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. The term load balancing refers to the distribution of workloads across multiple computing resources. 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. See http://go.microsoft.com/fwlink/?LinkID=155570 for more information. 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. These scenarios describe standard usage for a DataSet, describing its update and merge behavior. There is a load or parse error in the XML. This action value depends on the state of the row before the load operation. To load an assembly from a byte array with the trust level of the application domain, use the Load(Byte[], Byte[], SecurityContextSource) method overload. You can also access other server controls within the page's control hierarchy. The Upsert option facilitates aggregating changes from one or more secondary data sources. 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 Azure load balancer is a Layer-4 (TCP, UDP) load balancer that provides high availability by distributing incoming traffic among healthy VMs. For information about how to obtain the fully qualified assembly name, see Assembly Names. WebThe Load method provides a technique for filling a single DataTable with data, retrieved from an IDataReader instance. The value of securityContextSource is not one of the enumeration values. An array of DataTable instances, from which the Load(IDataReader, LoadOption, FillErrorEventHandler, DataTable[]) method retrieves name and namespace information. WebLoad (Stream) Creates a new XDocument instance by using the specified stream. All but one of the overloads for this method allows you to specify a load option parameter, indicating how rows already in a DataTable combine with rows being loaded. typeX denotes that there are four possible types: int, int2, int3 or int4. If a matching table is found, that table is loaded with the content of the current result set. Specifies the name and path of the file to be loaded. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. assemblyRef specifies a remote assembly, but the ability to execute code in remote assemblies is disabled. The following example uses the StringReader class to load a string of XML data into the XmlDocument object. An object that describes the assembly to load. 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. Microsoft makes no warranties, express or implied, with respect to the information provided here. ; Multiple columns at a time in the form of a vector like HistoricalPrices in the HousingData class. When working with the schema, the Load method may encounter conditions as described in the following table. Exceptions XmlException There is a load or parse error in the XML. Valid root keys for the local computer are: HKLM, HKCU, HKCR, HKU, and HKCC. This file must be created in advance by using the Microsoft makes no warranties, express or implied, with respect to the information provided here. More info about Internet Explorer and Microsoft Edge, http://go.microsoft.com/fwlink/?LinkID=155570, http://go.microsoft.com/fwlink/?LinkId=155570. 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. Azure Load Testing Preview is a fully managed load-testing service that enables you to generate high-scale load. If rawSymbolStore was specified, the raw bytes that represent the symbols for the assembly are also loaded. To load an extension DLL, you can do one of the following: Use the .load or .loadby command. ; If you have a vector property, apply the VectorType attribute to the property in your data model. Use the Show method to make the object visible. 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 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 offset type is dependent on the texture-object type, and needs to be static. If the file is not found, CodeBase is used to search for the assembly. The example uses the file, books.xml, as input. The assembly is loaded into the application domain of the caller. The Load method always preserves significant white space. Returns XDocument An XDocument object that reads the data that is contained in the stream. Some information relates to prerelease product that may be substantially modified before its released. 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. The specified path is invalid (for example, it is on an unmapped drive). The techniques shown in this topic apply equally to models created with Code First and the EF Designer. Until an object is visible, a user can't interact with it. Loads an assembly given its AssemblyName. For more information, see the Remarks section of the XmlReader reference page. This operation is not supported on the current platform. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. An assembly or module was loaded twice with two different evidences. If the DataTable already contains rows, the incoming data from the data source is merged with the existing rows. Direct3D guarantees to return zero for any resource that is accessed out of bounds. Loading Elements There are several different ways to load the elements: Use an x:Bind expression to specify the load state. You define a front-end IP configuration that contains one or more public The term load balancing refers to the distribution of workloads across multiple computing resources. When you use a Load method overload with a Byte[] parameter to load a COFF image, evidence is inherited from the calling assembly. The assembly is loaded into the application domain of the caller. The DataTable tracks changes, allowing synchronization with the primary data source. Call GetTemplateChild with the name that you defined on the element. Values in a DataColumn can be constrained through use of properties such as ReadOnly and AutoIncrement. See the documentation for the DataTableLoad method for more information on using this parameter. The final row (labeled "(Not present)") describes the behavior for incoming rows that don't match any existing row. 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. Be aware that setting the property to false causes the code that triggered the problem to throw an exception. A DataSet synchronizes or updates with a single primary data source. Parameters Object If a remote computer is specified, valid root keys are: HKLM and HKU. The example then calls the Load method, displaying the data both before and after the load operation. Valid root keys for the local computer are: HKLM, HKCU, HKCR, HKU, and HKCC. For more information, see Row States and Row Versions. WebLoad-balancing options. There is a set of screens provided and all are in .xaml extensions. Once the data has been loaded, the example displays the contents of all its tables in the Console window. The load operation will fail with an InvalidOperationException if any of the source data columns in the incoming reader are computed columns. 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. This method is a Microsoft extension to the Document Object Model (DOM). This method provides the same functionality, but allows you to load multiple result sets from an IDataReader into multiple tables within a DataSet. WebLoad Event Reference Feedback Definition Namespace: System. Load object The object placeholder represents an object expression that evaluates to an object in the Applies To list. There is a set of screens provided and all are in .xaml extensions. The expression should return true to load and false to unload the element. In this case, the method doesn't allow you to indicate the load option, and uses the default, PreserveChanges. If the registry key name contains a space, enclose the key name in quotes. Updates the current and original versions of the row with the value of the incoming row. Loads the assembly with a common object file format (COFF)-based image containing an emitted assembly, optionally including symbols for the assembly. With Azure Load Balancer, you can scale your applications and create highly available services. Next steps. typeX denotes that there are four possible types: int, int2, int3 or int4. 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". This file must be created in advance by using the Fills a DataTable with values from a data source using the supplied IDataReader. Until an object is visible, a user can't interact with it. Please see Office VBA support and feedback for guidance about the ways you can receive support and provide feedback. More info about Internet Explorer and Microsoft Edge, Load(Byte[], Byte[], SecurityContextSource), http://go.microsoft.com/fwlink/?LinkID=155570. For example, "ProcessorArchitecture=msil". See FullName. This file must be created in advance by using the. WebLoad (String) Load (Byte [], Byte []) Overloads Load (Byte []) Loads the Assembly with a common object file format (COFF) based image containing an emitted Assembly. C# Copy public static System.Xml.Linq.XDocument Load (System.IO.Stream stream); Parameters stream Stream The stream that contains the XML data. Rather than trapping the error, this example uses a FillErrorEventHandler delegate to investigate and handle the error. Evidence of the calling assembly and evidence of the COFF image are ignored. It's important to note that all of the elements in the vector 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. 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. An array of type byte containing the raw bytes representing the symbols for the assembly. The service simulates traffic for your applications, regardless of where they're hosted. 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 ). Key scenarios that you can accomplish using Azure Standard Developers, testers, and quality assurance (QA) engineers can use it to optimize application performance, scalability, or capacity. 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. If the match fails, a FileLoadException is thrown. The service simulates traffic for your applications, regardless of where they're hosted. 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. Shader Model 4.1 is available in Direct3D 10.1 or higher. A IDataReader that provides a result set. For more information, see Reading XML Data using XPathDocument and XmlDocument. Returns 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 Load method fills each supplied DataTable instance with data from a single result set from the source data reader. (The overload that doesn't allow you to specify the behavior uses the default load option.) Fills a DataTable with values from a data source using the supplied IDataReader. Returns XDocument An XDocument object that reads the data that is contained in the stream. Here are two examples of using Load. This file is in format. Given these two hypothetical data sources, a user is likely to require one of the following behaviors: Initialize DataTable from a primary data source. 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 argument type is dependent on the texture-object type. Loading Elements There are several different ways to load the elements: Use an x:Bind expression to specify the load state. Load balancer provides low latency and high throughput, and scales up to millions of flows for all TCP and UDP applications. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. 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 DataSet isn't responsible for tracking changes in order to allow synchronization with the secondary data source. The URL can be either a local file or an HTTP URL (a Web address). Exceptions XmlException There is a load or parse error in the XML. Reads texel data without any filtering or sampling. The assembly is loaded into the application domain of the caller using the specified source for the security context. Next steps. 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 ). The example then adds tables to a DataSet and attempts to fill the tables with data from a DataTableReader. Use an overload that does not take an Evidence parameter. 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. Microsoft makes no warranties, express or implied, with respect to the information provided here. Given these two hypothetical data sources, a user is likely to require one of the following behaviors: Initialize DataSet from a primary data source. Evidence of the calling assembly and evidence of the COFF image is ignored. When converting data, the Load method uses the same conversion rules as the DbDataAdapter.Fill method. 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. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. To specify a remote computer, include the computer name (in the format, Specifies the name and path of the file to be loaded. Some information relates to prerelease product that may be substantially modified before its released. These scenarios describe standard usage for a DataTable, describing its update and merge behavior. 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. WebLoad Event Reference Feedback Definition Namespace: System. Azure Load Testing Preview is a fully managed load-testing service that enables you to generate high-scale load. The assembly is loaded into the domain of the caller using the supplied evidence. This command is intended for use with temporary files that are used for troubleshooting or editing registry entries. Call GetTemplateChild with the name that you defined on the element. Microsoft makes no warranties, express or implied, with respect to the information provided here. The object that describes the assembly to be loaded. In this 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. To preserve the .reloc address for your C++ executable file, specify /fixed:no when you are linking. A FillErrorEventHandler delegate to call when an error occurs while loading data. 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). WebThis occurs because the form values have already been loaded. Developers, testers, and quality assurance (QA) engineers can use it to optimize application performance, scalability, or capacity. 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. The name resolution scheme for this method is the same as that followed by the Fill method of the DbDataAdapter class. A byte array that contains the raw bytes representing the symbols for the assembly. Methods which use evidence to sandbox are obsolete and will be removed in a future release of the .NET Framework. 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. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. To load the correct assembly, it's recommended to call the Load method by passing the long form of the assembly name. If the registry key name contains a space, enclose the key name in quotes. 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. When you use a Load method with an Evidence parameter, pieces of evidence are merged. Later the user intends to propagate changes back to the primary data source. 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. 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. 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. Firstly, I want to load a Main Screen file from 'C:\MainScreen.xaml'. Returns 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. The following example demonstrates how to use the SetDesktopLocation, Load, Activated, and Activate members. Specifies the name and path of the file to be loaded. This method allows you to specify a load option parameter, indicating how rows already in a DataTable combine with rows being loaded. The assembly is loaded into the domain of the caller using the supplied evidence. A texture-object type (except TextureCube or TextureCubeArray). The example then focuses on data issues, including handling the various loading options. If the current node and its siblings look like the following: Load throws an exception because a document cannot have two root level elements. In addition, a DataTable can accept incremental data from one or more secondary data sources. 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. You define a front-end IP configuration that contains one or more public In the .NET Framework version 2.0, processor architecture is added to assembly identity, and can be specified as part of assembly name strings. In each case, both events occur, and the action is the same for each. Occurs before a form is displayed for the first time. The raw bytes representing the symbols for the assembly are also loaded. Note that this method overload always creates a new Assembly object with its own mapping. Please use an overload of Load which does not take an Evidence parameter. The name resolution scheme for this method is the same as that followed by the Fill method of the DbDataAdapter class. Zone, Url and Site are inherited from the calling assembly, and Hash and StrongName are taken from the COFF assembly. To load assemblies into other application domains, use a method such as CreateInstanceAndUnwrap. Returns If the assembly is found using CodeBase, the display name is matched against the assembly. 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 object placeholder represents an object expression that evaluates to an object in the Applies To list. 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. To run the example, paste the following code in a form called Form1 containing a Button called Button1 and two Label controls called Label1 and Label2. Until an object is visible, a user can't interact with it. See the documentation for the Load method for more information on using this parameter.
