vc 窗口大小 限制窗口大小（The VC window size limits the size of the window） VC window size limit window size In fact, there are many ways, here are a few more common ways to come, Heres the example of the SDI framework window. 1. create a maximized window, and cannot change its size Well, first of all, in the InitInstance of the app class 1.1 add the front of the original pMainFrame-ShowWindow (m_nCmdShow) DWORD dwStyle = GetWindowLong (m_pMainWnd-m_hWnd, GWL_STYLE); = / dwStyle ~ (WS_SIZEBOX); DwStyle = ~ (WS_MAXIMIZEBOX); / / no maximum DwStyle = ~ (WS_MINIMIZEBOX); / / prohibited to minimize SetWindowLong (m_pMainWnd-m_hWnd, GWL_STYLE, dwStyle); M_pMainWnd-ShowWindow (SW_SHOWMAXIMIZED); / / maximum display //m_pMainWnd-ShowWindow (SW_SHOW); / / WS_SIZEBOX, display a fixed window size is defective. 1.2, then m_pMainWnd-ShowWindow (m_nCmdShow) can be deleted Effects: maximize window display, and minimize maximum, minimize, to limit window size Note: here the dwStyle = ~ (WS_SIZEBOX); note tune, because the property removed, will have trouble, this is when I most big display window, the taskbar is covered by other people, is really depressed, but if we dont have this property go out, then by dragging, still can change the window size, how to do it, really a headache, change a way of thinking. ================================================================================================ 2. general window size changes are caused by the user dragging the window border. So, we can capture the main window in the WM_NCHITTEST message response function CWnd: (OnNcHitTest): determine if the return value is HTRIGHT, HTLEFT, HTTOP, one of the HTBOTTOM four value if it is, that the user now click on one of the four border, at this time we should return to the HTCLIENT. well, the shape of the mouse will not become horizontal or vertical arrow, the user can not rely on drag to change the window size of the frame. Using class wizard to see the following, but did not find WM_NCHITTEST this
