    Loading Resource Bitmaps

    I am sick and tired of giving out my windows applications with bitmap files that are required. Does anyone know how to use a resource bitmap? Thanks in advance.

    Lightbulb I have something that might help!

    I know of some things you need:

    in your resource file, put:

    402 BITMAP "Bmp location"

    Then, in your main code:

    HBITMAP hBmp;

    case WM_CREATE:

    hBmp=LoadBitmap(Program's Instance, MAKEINTRESOURCE(402));

    break;

    The only thing I don't know how to do is use WM_PAINT to draw the Bitmap. This is as far as I've gotten. I hope I helped some.

    WM_CREATE:
    hInstance = ((LPCREATESTRUCT) lParam)->hInstance ;
    hBitmap = LoadBitmap (hInstance, TEXT ("BITMAP")) ;
    GetObject (hBitmap, sizeof (BITMAP), &bitmap) ;
    cxSource = bitmap.bmWidth ;
    cySource = bitmap.bmHeight ;

    WM_PAINT:
    hdcMem = CreateCompatibleDC (hdc) ;
    SelectObject (hdcMem, hBitmap) ;
    BitBlt (hdc, 1, 1, 50, 50, hdcMem, 0, 0, SRCCOPY)

    wm_destroy
    DeleteObject (hBitmap) ;

    wm_size
    cxClient = LOWORD (lParam) ;
    cyClient = HIWORD (lParam) ;

    i think that will work.
    arrh, i got nothing good to say.

    i chucked this code up in a hurry so i just went and check it to see if it works. and it worked fine for me. There is a few reasons i can guess why it wont be working. if it compiled okay then im guession when you named your bitmap you didnt name it "mybitmap" or "thepic" or whatever, but include it inside "" marks in the resource script. also when you call hBitmap = LoadBitmap (hInstance, TEXT ("BITMAP")) ; make sure you call
    TEXT ("mypic or whatever you called it"))
    arrh, i got nothing good to say.

    no, I don't think that's it. My compiler doesn't like anything in WM_SIZE or some stuff in wm_create

    omg... *BASIC* programming rules, any varable used must be declared first...

    static HBITMAP hBitmap ;
    static int cxClient, cyClient, cxSource, cySource;
    BITMAP bitmap ;
    HDC hdc, hdcMem ;
    HINSTANCE hInstance ;
    PAINTSTRUCT ps;

    i think that is all of them, if not just declare them.
    arrh, i got nothing good to say.

    Sorry, I just figured that out, but it still won't show! It compiles, though.
