Hi,

in case you have implented classA on Form1 and you later change your mind. Than whats wrong with slecting that class on form1 right click and delete classA subsequent add classB?
Seems quicker and neater than 'hacking' the SCX.

Also applies according to me for situation where you have subclassed your classA into classAA.

I would create a classB and subclass it to classBB.

Maybe just a matter of taste.

Regards,

Koen
