Can someone send me a source that demonstrates how to get into 640x480x256 gfx mode and plots a pixel?
That's the best way for me to learn things (look at sources, changing things etc.)

I have programmed a lot in DOS and I want to start programming in windows using DirectX.

I really recommend you get a book, since DirectDraw isn't near as easy as just plain DOS IMHO. That said, DirectDraw isn't hard to learn -- its just a bit different 
.
.Anyway, I'll send you the source to my DirectDraw graphics library if you want it. I personally think its pretty nice myself (I use it in all my projects), but theres plenty of room for improvement.

I've read a tutorial that explains how to use directdraw and has sources. Try to ran those sources and of course: They wouldn't run (ARGH!).
The compiler keeps moaning about: 'unreferenced external symbol _main'.
This only happens when I include 'ddraw.h'.
If I understand it well, I must start my program with WinMain, but that's impossible with main declared (writes to MS-DOS prompt).
When I try to run the source from main I will get a invalid operation error when it tries to create the primary surface. It didn't tried to access 640x480x256 either.

Before I was only asking if you wanted the sources, thats why I didn't send them -- I wasn't sure if you wanted them or not (Do you want them?). If your using VisualC++ you have to create a Win32 Application, not a Win32 console app (I don't know what you have to do with Borland).
In a windows program you should never use main, only WinMain(). Although you can create a window from a console app its not good style -- and from what your saying it doesn't sound like it works all the time.

Sorry for the misunderstanding,
of course I want the sources.
And the compiler I use is VC++ 6.0. For some reason you can't write a windows app. I don't know which option I should set that it can use WinMain (and stop bugging me with main).

Well, if you just want to run your DOS program in a console window, then just create a new WIN32 Console Application project and #include & in your program and it should fire up. I don't know about your proggie being able to request 800x600 8-Bit in a console window though.
And I do agree with an earlier post about getting "Windows Game Programming for Dummies". Don't let the "Dummies" fool ya as Andre Lamothe does quite well in explaining DirectX components DirectDraw,Sound,Input as well as Windows GDI. No Direct3D but he covers that in some of his other books (I think).

OOps, some of my post got dropped.. should read:
"just create a new WIN32 Console Application project, insert your dos code (using main()), #include windows.h & windowsx.h and it should fire right up."
