Hi

I have a COM written for Excel 2003 using C# and VSTO with a number of user
defined functions (UDF) that I write.

When the user click on "Insert function" inside Excel to bring up the window
where he can see and change all the function arguments I would like to
include my own help information where the user can click on "Help on this
function".

Does any one know how this can be done?

Thanks Torben
