I am writing a user defined function to calculate commissions for sales
associates in my company. I need a way to provide documentation with this
function. I'd like to use the Insert Function wizard to provide a definition
of the parameters like you see for built-in functions.

I've searched these forums for an answer to this question and I've found one
thread answering a similar question from Fredrik Wahlgren that mentions
creating chm files and linking them to the function using .idl files, but it
seems to be specific to C++. I'm a C++ challenged visual basic.NET
deveolper. Is there any way to use VBA or VB.NET to link a .chm file to a
user defined function? Is there an easier way to accomplish this?
