    How can I keep a window from being resized

    I am trying to make a windows calculator without using a dialog box but I don't want the main window to change size. Can anyone help with this? I am sure it is probably something simple but I am at a loss.

    Don't pass WS_SIZEBOX as a style parameter to CreateWindow. If you're using WS_OVERLAPPEDWINDOW as the window style (as most do) then do: WS_OVERLAPPEDWINDOW & ~WS_SIZEBOX

    if you set the ScreenRect to the desired size and location when the app starts.

    Then catch and modify the WM_MOVING (to stop movement if needed) and WM_SIZE (to stop resize)

    Then just let the default msg processing do its stuff using your original params.

    Code:
    case  WM_MOVING:
    ((RECT*)lParam)->left=rScreenRect.left;
    ((RECT*)lParam)->right=rScreenRect.right;
    ((RECT*)lParam)->top=rScreenRect.top;
    ((RECT*)lParam)->bottom=rScreenRect.bottom;
    break;

    Question

    I am a beginner for windows designing. And I am also thinking of entering some data and getting back some calculating results from a window, something like your calculator. Could you post your code so than I can have an idea of how to begin my program?
    Thanks.
