You should probably look up BitBlt() which is used for displaying graphics in win32.

I''ve tried this:

HBITMAP hbitmap;

BYTE buffer[50]={ 0, 0, 0, 0, 0,
0,255,255,255, 0,
0,255, 0, 0, 0,
0,255, 0, 0, 0,
0,255,255,255, 0,
0, 0, 0,255, 0,
0, 0, 0,255, 0,
0, 0, 0,255, 0,
0,255,255,255, 0,
0, 0, 0, 0, 0
}; // Image

hbitmap = CreateBitmap (5, 10, 1, 8, &buffer);
HDC hdc = GetDC(hwnd);
HDC image_dc = CreateCompatibleDC(hdc);

HBITMAP old_hbitmap = (HBITMAP)SelectObject(image_dc,hbitmap);

BitBlt(hdc,0,0,5,10,image_dc,0,0,SRCCOPY);

but it don''t display anything
