Hi,

I developed COM addin for excel in C#, We have many number of functions in
our addin. The user will type some function name in excel and then he clicked
on function wizard(fx) button. It will show function wizard with the argument
names, In that will show the link called as "Help on this function". When the
user clicked on that link, my own custom help should open, How can I do that.

I am expecting positive response from somebody.
