If CForm is generating (or receiving) the events, then your method would expand into the MFC way. I want them to derive from CForm, declare all there controls in this class, and set all events they wish to handle for all controls in this class.Quote: Ok, so it This means that timer1Event is a class method, it would be unable to access any object data through this as the this pointer is not set up for class methods. Error C2664 Cannot Convert Argument That should work.@allBy the way, why does C++ even care if the pointer arguments have the same const-qualifiers in both function signatures?
