Hi!

I developped an add-in containing a toolbox of functions to perform
some calculations.

However, I would like to create a kind of "easy-access" GUI for these
and the way I found was to create a new menu item with sub-menu/items
and the like.

However, my toolbox is for functions, not macros, so I cannot simply
run my function without any arguments when I select the item.
Therefore, I would like to open a user form with the options for this
function, just like the "Function Argument Window" that opens when we
use the standard function button on the menu. (I'm talking about the
menu with the arguments/tooltips)

Is there any way to call this "Window Argument Form" directly and
supply my function in argument and have it work just like if I clicked
on the main function button? If I can avoid creating a user form I
will as it's not really needed to have custom forms for my functions.

Thanks!
