    Start with WS_POPUP | WS_CAPTION and add the styles as you wish ...

    WS_MAXIMIZEBOX
    WS_MINIMIZEBOX
    WS_BORDER
    WS_SYSMENU

    ........yadda yadda......

    When your window is being resized it is sent a message. You can capture this message in your Window Procedure and then resize your window back to the way you want. You would have to use WM_SIZE or WM_SIZING. There is a way to make the maximize button so it cannot be clicked on. Using CreateWindow() you can use these styles:
    WS_MAXIMIZE Creates a window that is initially maximized.
    WS_MAXIMIZEBOX Creates a window that has a Maximize button. Cannot be combined with the WS_EX_CONTEXTHELP style. The WS_SYSMENU style must also be specified.
    WS_MINIMIZE Creates a window that is initially minimized. Same as the WS_ICONIC style.
    WS_MINIMIZEBOX Creates a window that has a Minimize button. Cannot be combined with the WS_EX_CONTEXTHELP style. The WS_SYSMENU style must also be specified.

    yeah that's pretty much what I use all the time, except that you don't need WS_CAPTION - I think it's included in WS_OVERLAPPED. If not, it's in one of the other ones
    Just Google It. √

    Another way to stop your windows being resized is to catch the

    WM_MOVING msg and replace its params. Put them back to the original.

    I keep an array bout my apps windows. It holds HDC's, HWND's, ID's and rects.

    So I just put the screen rect back into the msg param.

    case WM_MOVING:
    ((RECT*)lParam)->left=rScreenRect.left;
    //ect
    break;

    and let the default winproc take care of it.
