mmttb: I don't think you should play with the Windows API. You are not used to it and it looks too complicated for you.
Wait for PPL v1.0 it's got a better event handling system.
proc MyButtonClick (...)
end;
In v1.0 you just double-click the event you want to edit put the code and thats it.
It's not as simple as VB still but it's very close. Don't expect PPL to be another VB it's not the goal.
