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 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. 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. Do not use an AssemblyName with only the CodeBase property set. The URL can be either a local file or an HTTP URL (a Web address). 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 following example, UserForm2 is loaded during UserForm1's Initialize event. 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. 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. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Shader Model 4.1 is available in Direct3D 10.1 or higher. See the documentation for the Load method for more information on using this parameter. These values may be equivalent, or may be different if the data in the row has been changed since filling the DataTable. To load an extension DLL, you can do one of the following: Use the .load or .loadby command. This file must be created in advance by using the Exceptions XmlException There is a load or parse error in the XML. Let me explain it again. A value from the LoadOption enumeration that indicates how rows already in the DataTable are combined with incoming rows that share the same primary key. It's important to note that all of the elements in the vector 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. 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, Introduction to the ASP.NET Page Life Cycle. 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. Loads an Assembly given its display name. 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 assemblies into other application domains, use a method such as CreateInstanceAndUnwrap. When converting data, the Load method uses the same conversion rules as the DbDataAdapter.Fill method. The techniques shown in this topic apply equally to models created with Code First and the EF Designer. See FullName. C# public virtual void Load (string filename); Parameters filename String URL for the file containing the XML document to load. Before you save the document, you must add a root level element, otherwise Save will throw an exception. typeX denotes that there are four possible types: int, int2, int3 or int4. Load balancer provides low latency and high throughput, and scales up to millions of flows for all TCP and UDP applications. An array of DataTable instances, from which the Load(IDataReader, LoadOption, FillErrorEventHandler, DataTable[]) method retrieves name and namespace information. The read only constraint on a DataColumn is applicable only for changes that occur in memory. With Azure Load Balancer, you can scale your applications and create highly available services. These issues, and more, are controlled by the loadOption parameter. More info about Internet Explorer and Microsoft Edge, Load(IDataReader, LoadOption, DataTable[]), Load(IDataReader, LoadOption, FillErrorEventHandler, DataTable[]). 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. Returns XDocument An XDocument object that reads the data that is contained in the stream. Incremental data feed from secondary data sources. Load columns as: Individual columns like Size and CurrentPrices in the HousingData class. 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. C# Copy public static System.Xml.Linq.XDocument Load (System.IO.Stream stream); Parameters stream Stream The stream that contains the XML data. To preserve the .reloc address for your C++ executable file, specify /fixed:no when you are linking. An array of type byte containing the raw bytes representing the symbols for the assembly. [in] An optional offset applied to the texture coordinates before sampling. When working with the schema, the Load method may encounter conditions as described in the following table. Given these two hypothetical data sources, a user is likely to require one of the following behaviors: Initialize DataTable from a primary data source. ; Multiple columns at a time in the form of a vector like HistoricalPrices in the HousingData class. Loads an Assembly given its AssemblyName. 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. Specifies the name and path of the file to be loaded. 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. It's important to note that all of the elements in the vector The assembly is loaded into the application domain of the caller. Microsoft makes no warranties, express or implied, with respect to the information provided here. Later the user intends to propagate changes back to the primary data source. Set the property to false to indicate that you wish to halt processing. This method provides the same functionality, but allows you to load multiple result sets from an IDataReader into multiple tables within a DataSet. The loader does not continue probing for other assemblies that match the simple name. This file must be created in advance by using the When converting data, the Load method uses the same conversion rules as the Fill method. The Load method provides a technique for filling a single DataTable with data, retrieved from an IDataReader instance. Valid root keys for the local computer are: HKLM, HKCU, HKCR, HKU, and HKCC. filename specified a file that is read-only. Fills a DataTable with values from a data source using the supplied IDataReader. In this scenario, the user wants to take the DataSet filled in the previous scenario and perform an incremental synchronization with the primary data source, preserving modifications made in the DataSet. 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 stream containing the XML document to load. The DataSet tracks changes, allowing synchronization with the primary data source. This file must be created in advance by using the The Load extension method works just like ToList except that it avoids the creation of the list altogether. This operation is not supported on the current platform. It's important to note that all of the elements in the vector Remarks When an object is loaded, it is placed in memory, but isn't visible. The Load extension method works just like ToList except that it avoids the creation of the list altogether. A FillErrorEventHandler delegate to call when an error occurs while loading data. The assembly is loaded into the domain of the caller using the supplied evidence. Forms Assembly: System.Windows.Forms.dll Important Some information relates to prerelease product that may be substantially modified before its released. An IDataReader that provides a result set. See http://go.microsoft.com/fwlink/?LinkId=155570 for more information. 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 registry key name contains a space, enclose the key name in quotes. More info about Internet Explorer and Microsoft Edge, http://go.microsoft.com/fwlink/?LinkID=155570, http://go.microsoft.com/fwlink/?LinkId=155570. When you use a Load method with a Byte[] parameter and Evidence to load a COFF image, only the supplied evidence is used. The Load method must take into account three specific issues when loading the data from an IDataReader instance: schema, data, and event operations. Microsoft makes no warranties, express or implied, with respect to the information provided here. If a matching table is found, that table is loaded with the content of the current result set. There is a load or parse error in the XML. The evidence that first succeeds is the evidence that is used. A load balancer health probe monitors a given port on each VM and only distributes traffic to an operational VM. A load balancer health probe monitors a given port on each VM and only distributes traffic to an operational VM. The trust level of an assembly that is loaded by using this method is the same as the trust level of the calling assembly. 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). Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. In each case, both events occur, and the action is the same for each. Note that this method overload always creates a new Assembly object with its own mapping. 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. This file must be created in advance by using the. 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. . ; If you have a vector property, apply the VectorType attribute to the property in your data model. 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. 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. There is a set of screens provided and all are in .xaml extensions. When you use a Load method with an Evidence parameter, pieces of evidence are merged. These scenarios describe standard usage for a DataTable, describing its update and merge behavior. Remarks When an object is loaded, it is placed in memory, but isn't visible. The expression should return true to load and false to unload the element. SampleIndex must always be specified first with multi-sample textures. ; If you have a vector property, apply the VectorType attribute to the property in your data model. This file is in format. A DataSet synchronizes or updates with a single primary data source. The following example demonstrates several of the issues involved with calling the Load method. When you use a Load method overload with a Byte[] parameter to load a common object file format (COFF) image, evidence is inherited from the calling 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. Windows. After each result set, the Load method moves on to the next result set within the reader, until there are no more result sets. URL for the file containing the XML document to load. You define a front-end IP configuration that contains one or more public Updates the original version of the row with the value of the incoming row. The term load balancing refers to the distribution of workloads across multiple computing resources. The XmlReader used to feed the XML data into the document. Notifies the server control to perform any processing steps that are set to occur on each page request. When an object is loaded, it is placed in memory, but isn't visible. 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. Applies to See also Introduction to the ASP.NET Page Life Cycle Recommended content UpdatePanel (System.Web.UI) LinkButton (System.Web.UI.WebControls) Web See Row States and Row Versions for more information. Key scenarios that you can accomplish using Azure Standard 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 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. Version 2.0 or later of the common language runtime is currently loaded and assemblyRef was compiled with a later version. Loads an assembly given its display name, loading the assembly into the domain of the caller using the supplied evidence. This method is a Microsoft extension to the Document Object Model (DOM). 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. Use the Show method to make the object visible. Loading Elements There are several different ways to load the elements: Use an x:Bind expression to specify the load state. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. 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. Occurs when the server control is loaded into the Page object. Incremental data feed from secondary data sources. 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. WebTo load the correct assembly, it's recommended to call the Load method by passing the long form of the assembly name. The assembly is loaded into the application domain of the caller. The following example loads the last book node of the books.xml file into the XML document. Call FindName with the name that you defined on the element. Some information relates to prerelease product that may be substantially modified before its released. Be aware that setting the property to false causes the code that triggered the problem to throw an exception. Whether certain permissions are granted or not granted to an assembly is based on evidence. See http://go.microsoft.com/fwlink/?LinkID=155570 for more information. Loads the XML document from the specified XmlReader. The loader does not continue probing for other assemblies that match the simple name. 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). Execute an extension by issuing the full !DLLName.ExtensionCommand syntax. Microsoft makes no warranties, express or implied, with respect to the information provided here. If the assembly is found using CodeBase, the display name is matched against the assembly. Azure Load Testing Preview is a fully managed load-testing service that enables you to generate high-scale load. This partial code example is from the Paint.fx file in the AdvancedParticles Sample. Developers, testers, and quality assurance (QA) engineers can use it to optimize application performance, scalability, or capacity. The assembly is loaded into the application domain of the caller using the specified source for the security context. The following example instantiates an AssemblyName object and uses it to load the sysglobal.dll assembly. Firstly, I want to load a Main Screen file from 'C:\MainScreen.xaml'. The following table describes the three load options provided by the LoadOption enumeration. An IDataReader that provides one or more result sets. 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 ). If a remote computer is specified, valid root keys are: HKLM and HKU. One or more DataTable's contents are modified. Fills a DataTable with values from a data source using the supplied IDataReader. securityEvidence is not null. Methods which use evidence to sandbox are obsolete and will be removed in a future release of the .NET Framework. Updates the current version of the row with the value of the incoming row. Until an object is visible, a user can't interact with it.
