Bet there are other two-pointer messages with similar form: a struct to say what to do, a buffer to send or receive data. --- In [email protected], "entropyreduction" <alancampbelllists+ya...@...> wrote: > > Im looking at code that dialog plugin uses to do a sendmessage. > > I need to do some fancy footwork (somewhat more complicated than what Sheri's > been doing if I still want to maintain compatibility with W9x). > I nicked appropriate code from autohotkey ages ago. > > But, I need to know: > > are there messages that require > > lParam to be a pointer to data (yes) > lParam to be a pointer to buffer to receive data (yes) > wParam to be a pointer to data (???) > wParam to be a pointer to buffer to receive data (???) > both wParam _and_ lParam to be a pointer to buffer? > > Can't figure how to frame that question to google.
