IDataInitialize

OLE DB Programmer's Reference

Use the IDataInitialize interface to create a data source object using a connection string. You can also retrieve a connection string from an existing data source object.

To build a connection string, use the prompting user interface available through the IDBPromptInitialize interface and then use IDataInitialize to get a data source object based on that connection string.

For more information, see "Creating Data Source Objects" in Chapter 2: Data Source and Session Objects.

When to Call

Call IDataInitialize to provide a common entry point for consumers to obtain a data source object or to get persistent data source information.
