Methods

	Name	Description
	CreateObject	Creates a DDEX-provider implemented object of the given type that is specialized for the specified data source.
	DeriveDataSource	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 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 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 very differently against different data sources. The most extreme example is with generic providers like OLE DB and ODBC whose specific provider or driver defines the behavior. A simpler example is the differentiation between a SQL Server connection and a SQL Server Database File connection.

While the same provider is used to connect to each data source, the design time experience may be very different. A DDEX provider can implement this class to provide ways of customizing 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.
