Add Calendar to User Form on a Mac

I found a wonderful calendar produced by BlueCactus that will work in Excel for Mac. Since Macs don't allow Active X controls this is wonderful. I have a User Form and wanted to know if this can be used on the User Form in the same way that it is used within a cell in Excel. If so, what control should be put on the form to utilize the code?

I believe the KB article is 791

Does it work when you tried it?
