Methods
Name | Description | |
---|---|---|
CreateObject | Creates a DDEX provider–implemented object of the given type that is specialized for the specified data source. | |
DeriveSource | Determines which data source supported by the provider is represented by the given connection string. | |
Equals | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) | |
Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) | |
GetAssembly | Locates an assembly, given an assembly string and a data source GUID. | |
GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) | |
GetType() | Gets the Type of the current instance. (Inherited from Object.) | |
GetType(Guid, String) | Retrieves a type definition, given a type name and a data source GUID. | |
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) | |
ToString | Returns a string that represents the current object. (Inherited from Object.) |

Remarks
Some DDEX providers behave differently when connected to different data sources. The most extreme example is with generic providers like OLE DB and ODBC, whose specific providers or drivers define their behavior. A simpler example is the differentiation between a SQL Server connection and a SQL Server Database File connection.
Although the same provider is used to connect to each data source, the design time experience may be different. A DDEX provider can implement this class to provide ways of customizing the behavior of the provider, depending on its data source.
Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
