Adding arugment descriptions isn't really supported in VBA.


You can look at Laurent Longre's pages on this topic:

the first article is a download and offers a DLL you can use to
add arguments descriptions I believe. The second is pretty specialized and
not a general
solution. I have heard it really only works for situations identical to the
example.

I can show the discription for the UDF function.
How can I show help for the function arguments just like
the built in function?

Thanks,
