Hi all,

I have written a custom VBA function and would like to use it in Excel. But for my users sake, I would like to have the feature as other excel built-in functions have - when we type in "=func(" then a yellow text pop-up shown to notify user what parameter is to be entered.

I have done some research about this and know this is actually quite a big task. I have made the .chm file, associating Help Context ID with some text I want.

But my question is how to associate the VBA function to the help file in such a way that when "=myCustomFunc(" are typed in, the help string pop up?

Any help is greatly appreciated.
