Check if a sub exists

Hi. Is there a way to check if a sub exists in another form? I want to run a sub "form2.dosomething" from form1 but form2 might not have a sub called "dosomething". If it doesnt then i want it to ignore it. I would also like to do it without an error handler.

I know it sounds daft but im loading multiple instances of forms which have to access a sub in the "owner form" which could be any other form

Isn't that what Modules are for?

Sorry i dont get you.

I have some forms which have a variable that stores the "parent form". When they unload the have to run a sub in the parent form but some parent forms dont have the sub

Sometimes the obvious thing escapes us!

Why not simply go through all your possible "parent forms" and add a common element to all of them. This could be a wrapper function that reports back if that specific form has the subroutine in question or not. Seems simple enough.

I could add the sub i want to every form but i was hoping not to do that
