說明：
以下函數對於POPUP窗口有效，對於子窗口好像不行。
//最小化按鈕有效 ::SetWindowLong(m_hWnd,GWL_STYLE,GetWindowLong(m_hWnd,GWL_STYLE) | WS_MINIMIZEBOX ); ::SetWindowPos(m_hWnd,NULL,0,0,0,0,SWP_NOMOVE|SWP_NOSIZE|SWP_FRAMECHANGED); //最小化按鈕無效 ::SetWindowLong(m_hWnd,GWL_STYLE,GetWindowLong(m_hWnd,GWL_STYLE) &~WS_MINIMIZEBOX ); ::SetWindowPos(m_hWnd,NULL,0,0,0,0,SWP_NOMOVE|SWP_NOSIZE|SWP_FRAMECHANGED); //最大化按鈕有效 ::SetWindowLong(m_hWnd,GWL_STYLE,GetWindowLong(m_hWnd,GWL_STYLE) | WS_MAXIMIZEBOX ); ::SetWindowPos(m_hWnd,NULL,0,0,0,0,SWP_NOMOVE|SWP_NOSIZE|SWP_FRAMECHANGED); //最大化按鈕無效 ::SetWindowLong(m_hWnd,GWL_STYLE,GetWindowLong(m_hWnd,GWL_STYLE) &~WS_MAXIMIZEBOX ); ::SetWindowPos(m_hWnd,NULL,0,0,0,0,SWP_NOMOVE|SWP_NOSIZE|SWP_FRAMECHANGED); //關閉按鈕有效 ::EnableMenuItem(::GetSystemMenu(m_hWnd,false),SC_CLOSE,MF_BYCOMMAND | MF_GRAYED); //關閉按鈕無效 ::EnableMenuItem(::GetSystemMenu(m_hWnd,false),SC_CLOSE,MF_BYCOMMAND | MF_ENABLED); //工具欄窗口。在任務欄上沒有程序顯示,需要添加在OnInitDialog()里 ::SetWindowLong(m_hWnd,GWL_EXSTYLE,GetWindowLong(m_hWnd,GWL_EXSTYLE) &~WS_EX_APPWINDOW|WS_EX_TOOLWINDOW ); ::SetWindowPos(m_hWnd,NULL,0,0,0,0,SWP_FRAMECHANGED|SWP_NOMOVE|SWP_NOSIZE); //添加標題欄 ::SetWindowLong(m_hWnd,GWL_STYLE,GetWindowLong(m_hWnd,GWL_STYLE) | WS_CAPTION ); ::SetWindowPos(m_hWnd,NULL,0,0,0,0,SWP_NOMOVE|SWP_NOSIZE|SWP_FRAMECHANGED); //取消標題欄 ::SetWindowLong(m_hWnd,GWL_STYLE,GetWindowLong(m_hWnd,GWL_STYLE) & ~WS_CAPTION ); ::SetWindowPos(m_hWnd,NULL,0,0,0,0,SWP_NOMOVE|SWP_NOSIZE|SWP_FRAMECHANGED); //取消標題欄，保留3d邊框，可調整窗口大小 ::SetWindowLong(m_hWnd,GWL_STYLE, GetWindowLong(m_hWnd,GWL_STYLE) & ~WS_CAPTION | WS_THICKFRAME ); ::SetWindowPos(m_hWnd,NULL,0,0,0,0,SWP_NOMOVE|SWP_NOSIZE|SWP_FRAMECHANGED); //一定要加這句設置才會立即生效 //取消標題欄和3d邊框，保留一個線條的細邊框，不能調整窗口大小 ::SetWindowLong(m_hWnd,GWL_STYLE,GetWindowLong(m_hWnd,GWL_STYLE) & ~WS_CAPTION & ~WS_THICKFRAME | WS_BORDER ); ::SetWindowPos(m_hWnd,NULL,0,0,0,0,SWP_NOMOVE|SWP_NOSIZE|SWP_FRAMECHANGED); //如果有WS_EX_DLGMODALFRAME還要取消WS_EX_DLGMODALFRAME // ::SetWindowLong(m_hWnd,GWL_EXSTYLE,GetWindowLong(m_hWnd,GWL_EXSTYLE) // & ~WS_EX_DLGMODALFRAME); // ::SetWindowPos(m_hWnd,NULL,0,0,0,0,SWP_FRAMECHANGED|SWP_NOMOVE|SWP_NOSIZE); //取消所有邊框 ::SetWindowLong(m_hWnd,GWL_STYLE,GetWindowLong(m_hWnd,GWL_STYLE) & ~WS_CAPTION & ~WS_THICKFRAME ); ::SetWindowPos(m_hWnd,NULL,0,0,0,0,SWP_NOMOVE|SWP_NOSIZE|SWP_FRAMECHANGED); // //如果有WS_EX_DLGMODALFRAME還要取消WS_EX_DLGMODALFRAME // ::SetWindowLong(m_hWnd,GWL_EXSTYLE,GetWindowLong(m_hWnd,GWL_EXSTYLE) // & ~WS_EX_DLGMODALFRAME); // ::SetWindowPos(m_hWnd,NULL,0,0,0,0,SWP_FRAMECHANGED|SWP_NOMOVE|SWP_NOSIZE); VC++6.0 如何去掉MFC向導生成的SDI程序中視圖邊框的3D效果2010-03-24 17:48先要去掉view的邊框，代碼如下： BOOL CSDIView::PreCreateWindow(CREATESTRUCT& cs) { cs.style &=~WS_BORDER;//加入的代碼 return CFormView::PreCreateWindow(cs); } 然后在去掉外部Frame的客戶區邊框，代碼如下： BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs) { if( !CFrameWnd::PreCreateWindow(cs) ) return FALSE; cs.dwExStyle&=~WS_EX_CLIENTEDGE;//加入的代碼，一定要在CFrameWnd::PreCreateWindow(cs)之后執行 return TRUE; }
