David I'm doubtfull about the assertion that only dialogs can be modal. I think
that every windows are create using CreateWindowEx() and others function like
MessageBox() or CreateDialog are only higher level functions that calls
CreateWindowEx(). As I suggested earlier if I was you I would try DS_SYSMODAL
flag for window style even if it begin with DS_ it doesn't mean that would not be
valid in a CreatWindowEx() call. After all CreateDialog use WS_ constants in
it's style
parameter why not the opposite.
IMHO there is no difference between a dialog and a normal windows as much as
creation is concern. I make a guess that the modality is a question of style.
Well I didn't take the time to test it but I bet my dollar of the month on it :)
