If you are using the SENDMESSAGE3 procedure to call LM_CREATE, then you are
sending SELF.  The TButton has a owner property that is a TControl and
tcontrol's have handles....  See how you get the handle from that?

Wherever the SendMessage3(LM_Create,Self) is, make sure the TCOntrol was
created because that's where the FOWNER is set (I think) and the owner
property can be typecast to a TControl to get it's handle....
