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. I might have to find an api expert to ask. Worst case is obviously the last. And I'll need to add some kind of spec that tells plugin whether pointers are do data structures, or to buffers for receiving data back.
