You did not assign the lpfnWndProc, hbrBackground, or hIconSm members.  Once
I gave those members real values, the code worked fine for me.

Note also that you can specify the LocalWindProc() pointer to your
TWndClassEx.  Then you don't need to use SetWindowLong() to set the window
procedure later.  You should call MakeObjectInstance() in your class's
constructor and FreeObjectInstance() in the destructor.  You don't need to
call call MAkeObjectInstance() everytime you create a new window.
