    Without using some other library (as far as I know) you can't use anything but a BMP.

    Are you confident using HDC's?
    Have you got code for a framebuffer/screenDC?
    Can you do the repaint?

    Look at this thread for these bits of code
    "Errors with resource bitmaps....HELP PLEASE!"

    Start with a simple bmp created in the resource editor and move up.

    Load it with
    hBitmap=LoadBitmap(hInstance,MAKEINTRECOURCE(IDD_M YBMP);

    Create your HDC's, load and select the hBitmap in to a temp HDC. StretchBlt() / BitBlt() the temp HDC to the framebuffer, call your function to update the screenDC. Call a paint with InvalidateRect()

    HDC = Handle to a Device Context

    Simply a blank sheet to draw to.

    A button has a HDC that you can GetDC() with. Then draw to the HDC and use BitBlt() to draw the changed HDC back to the button.
    (BitBlt() is same size StretchBlt() is bigger/ smaller).

    Its not simple. It requires a large framework under the drawing to allow fast updates to the screen. Think of it as the same as the first callback you wrote.

    PS Should have an extra ) and a spelling error in the previous post.

    hBitmap=LoadBitmap(hInstance,MAKEINTRESOURCE( IDD_MYBMP));

    hmm thats quite interesting does that mean that the HDC is like the first place where the button is drawn then it is drawn to the screen and then it is changed again by the HDC and then drawn again like updating the screen using to um things to draw on?
    thats quite cool actually I'm gonna like this stuff cheers man I just cant check that out right now I'll have to come back and read it later


    thanks again


    cheers

    ...or you're just a Bogumil Hrabal fan, isn't it? ;)

    Hrabal is (was, as he died a few years ago) a great czech writer, who did not use any puntuation signs, thus giving his thoughts an incredible lilt.

    Well, sometimes very hard to interprete, his books might cause physical pain and brain damage those who are only familiar with cartoons and hollywood-movies . (even I got headache after 10 pages, though being a very tough european guy :P)

    Was that your intention, too?
    ...or what the hell?
