The techniques shown in this topic apply equally to models created with Code First and the EF Designer. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. The output is displayed in the console window. The document begins loading at this point. Specifies the name and path of the file to be loaded. The example then calls the Load method, displaying the data both before and after the load operation. The evidence that first succeeds is the evidence that is used. 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.) 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. This method automatically detects the string format of the input XML (for example, UTF-8, ANSI, and so on). 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. WebLoad Event Reference Feedback Definition Namespace: System. C# Copy public static System.Xml.Linq.XDocument Load (System.IO.Stream stream); Parameters stream Stream The stream that contains the XML data. 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. Execute an extension by issuing the full !DLLName.ExtensionCommand syntax. (If you want finer control over the behavior of incoming data, see DataTable.Load.) Valid root keys for the local computer are: HKLM, HKCU, HKCR, HKU, and HKCC. 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). 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. In this case, the document remains empty. You define a front-end IP configuration that contains one or more public Here are two examples of using Load. Windows. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Microsoft makes no warranties, express or implied, with respect to the information provided here. WebLoad (Stream) Creates a new XDocument instance by using the specified stream. Remarks Once the data has been loaded, the example displays the contents of all its tables in the Console window. The loadOption parameter allows you to specify how you want the imported data to interact with existing data, and can be any of the values from the LoadOption enumeration. WebThis occurs because the form values have already been loaded. Be aware that setting the property to false causes the code that triggered the problem to throw an exception. For more information, see the Remarks section of the XmlReader reference page. Instead, the common language runtime tries to load the assembly into the calling application domain. These values may be equivalent, or may be different if the data in the row has been changed since filling the DataTable. The first is taken from a Windows Forms data binding application where Load is used to Microsoft makes no warranties, express or implied, with respect to the information provided here. Use the Show method to make the object visible. This partial code example is from the Paint.fx file in the AdvancedParticles Sample. See http://go.microsoft.com/fwlink/?LinkID=155570 for more information. Loads an assembly given its display name, loading the assembly into the domain of the caller using the supplied evidence. 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. A file that was found could not be loaded. 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. See the documentation for the Load method for more information on using this parameter. 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 this case, the method doesn't allow you to indicate the load option, and uses the default, PreserveChanges. WebThe Load method provides a technique for filling a single DataTable with data, retrieved from an IDataReader instance. More info about Internet Explorer and Microsoft Edge, Reading XML Data using XPathDocument and XmlDocument. This action value depends on the state of the row before the load operation. ; If you have a vector property, apply the VectorType attribute to the property in your data model. typeX denotes that there are four possible types: int, int2, int3 or int4. 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. The caller does not have the required permission. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. 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 first is taken from a Windows Forms data binding application where Load is used to 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. Fills a DataSet with values from a data source using the supplied IDataReader. (The overload that doesn't allow you to specify the behavior uses the default load option.) Loads an assembly with the specified name. A load balancer health probe monitors a given port on each VM and only distributes traffic to an operational VM. The value of securityContextSource is not one of the enumeration values. The errorHandler parameter is a FillErrorEventHandler delegate that refers to a procedure that is called when an error occurs while loading data. Next steps. 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. The Load method fills each supplied DataTable instance with data from a single result set from the source data reader. This has the following results. If a remote computer is specified, valid root keys are: HKLM and HKU. Azure Load Testing Preview is a fully managed load-testing service that enables you to generate high-scale load. If you want validation to occur, you can create a validating XmlReader instance by using the XmlReaderSettings class and the Create method. WebLoad (String) Loads the XML document from the specified URL. The service simulates traffic for your applications, regardless of where they're hosted. For information about how to obtain the fully qualified assembly name, see Assembly Names. ; Multiple columns at a time in the form of a vector like HistoricalPrices in the HousingData class. Load balancer supports both inbound and outbound scenarios. The term load balancing refers to the distribution of workloads across multiple computing resources. 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. Firstly, I want to load a Main Screen file from 'C:\MainScreen.xaml'. Load object The object placeholder represents an object expression that evaluates to an object in the Applies To list. An Azure load balancer is a Layer-4 (TCP, UDP) load balancer that provides high availability by distributing incoming traffic among healthy VMs. 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 file is not found, CodeBase is used to search for the assembly. Occurs before a form is displayed for the first time. This action value varies, depending on the state of the row before the load operation. An Azure load balancer is a Layer-4 (TCP, UDP) load balancer that provides high availability by distributing incoming traffic among healthy VMs. 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. Zone, Url and Site are inherited from the calling assembly, and Hash and StrongName are taken from the COFF assembly. Here are two examples of using Load. 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. 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 object can be manipulated programmatically in its Initialize event procedure. Some information relates to prerelease product that may be substantially modified before its released. The assembly is loaded into the application domain of the caller. When you use a Load method with a Byte[] parameter and Evidence to load a COFF image, only the supplied evidence is used. Call FindName with the name that you defined on the element. Load balancing aims to optimize resource use, maximize throughput, minimize response time, and avoid overloading any single resource. Firstly, I want to load a Main Screen file from 'C:\MainScreen.xaml'. The following Console application example first creates tables and loads data from a reader into a DataSet, using the Load method. WebTo load the correct assembly, it's recommended to call the Load method by passing the long form of the assembly name. Each of these tables must be a member of the DataTableCollection contained by this DataSet. An assembly or module was loaded twice with two different evidences. This version of the Load method attempts to preserve the current values in each row, leaving the original value intact. Loads the Assembly with a common object file format (COFF) based image containing an emitted Assembly. An IDataReader that provides a result set. The load operation will fail with an InvalidOperationException if any of the source data columns in the incoming reader are computed columns. Be aware that setting the property to false causes the code that triggered the problem to throw an exception. Evidence of the calling assembly and evidence of the COFF image is ignored. Do not use an AssemblyName with only the CodeBase property set. WebTo load the correct assembly, it's recommended to call the Load method by passing the long form of the assembly name. A DataTable synchronizes or updates with a single primary data source. Pieces of evidence supplied as an argument to the Load method supersede pieces of evidence supplied by the loader. -or-. Execute an extension by issuing the full !DLLName.ExtensionCommand syntax. Version 2.0 or later of the common language runtime is currently loaded and assemblyRef was compiled with a later version. You define a front-end IP configuration that contains one or more public For other examples that might be available, see the individual overload topics. Exceptions XmlException There is a load or parse error in the XML. By default, legacy CAS policy is not enabled in the .NET Framework 4; when it is not enabled, securityEvidence must be null. The example then displays the full name of the assembly's public types. C# Copy public static System.Xml.Linq.XDocument Load (System.IO.Stream stream); Parameters stream Stream The stream that contains the XML data. Load object The object placeholder represents an object expression that evaluates to an object in the Applies To list. A byte array that is a COFF-based image containing an emitted assembly. In this scenario, the user wants to initialize an empty DataTable with values from the primary data source. To load an extension DLL, you can do one of the following: Use the .load or .loadby command. An Azure load balancer is a Layer-4 (TCP, UDP) load balancer that provides high availability by distributing incoming traffic among healthy VMs. 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. Please use an overload of Load which does not take an Evidence parameter. More info about Internet Explorer and Microsoft Edge, Load(IDataReader, LoadOption, FillErrorEventHandler). 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. 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 provides low latency and high throughput, and scales up to millions of flows for all TCP and UDP applications. 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. 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. A IDataReader that provides a result set. 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. There is a set of screens provided and all are in .xaml extensions. Microsoft makes no warranties, express or implied, with respect to the information provided here. Load balancer supports both inbound and outbound scenarios. A load balancer health probe monitors a given port on each VM and only distributes traffic to an operational VM. WebLoad (String) Loads the XML document from the specified URL. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. WebTo load the correct assembly, it's recommended to call the Load method by passing the long form of the assembly name. The argument type is dependent on the texture-object type. In this Set the property to false to indicate that you wish to halt processing. The following table describes the three load options provided by the LoadOption enumeration. Call FindName with the name that you defined on the element. The raw bytes representing the symbols for the assembly are also loaded. Forms Assembly: System.Windows.Forms.dll Important Some information relates to prerelease product that may be substantially modified before its released. Incremental data feed from secondary data sources. Loads an assembly given its AssemblyName. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. 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. An I/O error occurred while opening the file. 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. Some information relates to prerelease product that may be substantially modified before its released. 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 XmlReader used to feed the XML data into the document. For example, "ProcessorArchitecture=msil". WebLoad (Stream) Creates a new XDocument instance by using the specified stream. Loads the Assembly with a common object file format (COFF) based image containing an emitted Assembly. Some information relates to prerelease product that may be substantially modified before its released. Updates the current version of the row with the value of the incoming row. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. 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). Have questions or feedback about Office VBA or this documentation? This applies to the .NET Framework version 1.1 Service Pack 1 (SP1) and subsequent releases. 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. Given these two hypothetical data sources, a user is likely to require one of the following behaviors: Initialize DataTable from a primary data source. assemblyRef specifies a remote assembly, but the ability to execute code in remote assemblies is disabled. typeX denotes that there are four possible types: int, int2, int3 or int4. The Upsert option facilitates aggregating changes from one or more secondary data sources.
