To create a TypeLib for your Enum collection:
The following code, after compiling, would give you a typelib with exactly 1 enum with 5 elements. You could add others as needed. To compile, you will need something like mktyplib.exe that comes with VC++. Note the GUIDs -- be sure and create unique ones on your machine. I used the GUID-generator to VC++ to do it, but you can also create your own mini-VB program to do it.
