Ok. I got a block of memory, char [640][480], and every character in it represents a pixel color. I want to blit this block of data to the screen. I know how to, using memcpy, but how do i get in in the right mode? I want to do this all from windows, remember. I want full screen graphics, and a mouse. I would prefer not to use DirectX. Any suggestions, site referances, code...anything? Thanks-

You must use for this Windows API:
BitBlt/StretchBlt. For create Bitmap you can use
CreateBitmapIndirect. But before this
you must learn any book
about Windows/Bitmaps/DIB and so on.(I recomend you
Petzold or Tom Swan books). In this boks there are many
examples of Display Bitmaps, make colors ...

If you already have the array setup, then look at SetDIBitsToDevice and StretchDIBits.  

Quite a few examples on these two.

i need more information on how to allow my program to use all of The screen. I want it to be the only posssible window on the screen, say, like C&C Red Alert. It takes up full screen. Do i need to change modes to allow read/write to that memory? "How do i get my program to run unwindowed full screen" is basicly what i'm asking.
thanks for the time

For cretion you main Window, you must use
WS_POPUP style, as in example:

int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance,
                    PSTR szCmdLine, int iCmdShow)
     {
     static char szAppName[] = "HelloWin" ;
     HWND        hwnd ;
     MSG         msg ;
     WNDCLASS  wndclass ;

     wndclass.style         = CS_HREDRAW | CS_VREDRAW ;
     wndclass.lpfnWndProc   = WndProc ;
     wndclass.cbClsExtra    = 0 ;
     wndclass.cbWndExtra    = 0 ;
     wndclass.hInstance     = hInstance ;
     wndclass.hIcon         = LoadIcon (NULL, IDI_APPLICATION) ;
     wndclass.hCursor       = LoadCursor (NULL, IDC_ARROW) ;
     wndclass.hbrBackground = (HBRUSH) GetStockObject (WHITE_BRUSH) ;
     wndclass.lpszMenuName  = NULL ;
     wndclass.lpszClassName = szAppName ;

     RegisterClass (&wndclass) ;

     hwnd = CreateWindow (szAppName,// window class name
                "Hello Program",     // window caption
                WS_POPUP,     // window style
                0,           // initial x position
                0,           // initial y position
                640,           // initial x size
                480,           // initial y size
                NULL,
                NULL,
                hInstance,
                NULL) ;

     ShowWindow (hwnd, iCmdShow) ;
     UpdateWindow (hwnd) ;

     while (GetMessage (&msg, NULL, 0, 0))
          {
          TranslateMessage (&msg) ;
          DispatchMessage (&msg) ;
          }
     return msg.wParam ;
     }
After that you can display you text/Bitmap/Lines ... for
full screen.
Regards, Alex
