Quite a lot of Windows 3 programs are using bitmaps on pushbuttons (eg. SETUP (F3 = door), various pushbuttons with the help program etc.). In my copy of the (beta) SDK no functions can be found on doing tricks like that and I also can't find no examples how to achieve this. I'd really hate to reinvent the wheel. Is there anyone in netland willing to mail me an example of how to achieve this? Thanx!

Hi! If you're lucky enough, your beta-SDK includes a sample program 'Rainbow'. It's an example of programming 'User-Defined controls'. There's also an article in one of the latest issues of Microsoft Systems Journal (which I pity having forgotten the number of - check issues after March '90). In principle, you'll need to write a DLL which will support the control's run-time functions (i.e. it's WinProc), a few functions used by DIALOG.EXE when creating a dialog to use the control plus LibMain and WEP, which are oblicatory (well, almost) for any DLL anyway.

Actually, there's a MUCH easier way to create those neat buttons with the bitmaps. There is a button style (BS_OWNERDRAW I believe) that will cause a button to send a message (WM_DRAWITEM) to it's parent Window whenever redrawing itself. Along with the WM_DRAWITEM message comes a structure that has various bits set to tell whether the button is down, checked, etc. Using this you can use the Paint program that comes with Windows, draw two buttom images (one in down state, one in up state), and then merely do a StretchBlt of that image in the client space of the button (also contained in the WM_DRAWITEM structure). It's pretty cool. Patrick -- "What's in a name? That which we call a rose by any other name would smell as sweet."
