Hello, I am using VBA in Excel XP with Windows 2000

Is it possible to set a reference to a library in another file using VBA in Excel

For example, the main program resides in "File A" and it must programmatically set a reference to "Microsoft Outlook 10.0 Object Library" in "File B" for "File B's" use

If this is possible, can someone supply me with the code with which to do it

Thanks much in advance.
