>Since it seems that whatever you do, you still have to modify in all places from where you make this call (unless you have a special class to deal with this), I think the easiest solution is to send the THIS object as a parameter to the second form. In this way, you have just one line (the one where you call the second form) to modify in more places and you can do all the rest (enable, disable the calling button) in the called form.

Another good idea, I'll have to try them all.
