I see helpful geniuses often refer to windows libs in the forums, where do I
find documentation on these libs, like how did you know ole32 had the guid
feature? Thx

I wish to create a GUID in a cell. I could put it on a macro button on the
toolbar. Does Excel have anything built in to do this, or do I need VBA
code. I would appreciate a sample.
