VC 修改窗口属性

修改窗口属性

说明：

以下函数对于POPUP窗口有效，对于子窗口好像不行。

//最小化按钮有效

::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);

//最小化按钮无效

::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);

//最大化按钮有效

::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);

//最大化按钮无效

::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);

//关闭按钮有效

::EnableMenuItem(::GetSystemMenu(m_hWnd,false),SC_CLOSE,MF_BYCOMMAND | MF_GRAYED);

//关闭按钮无效

::EnableMenuItem(::GetSystemMenu(m_hWnd,false),SC_CLOSE,MF_BYCOMMAND | MF_ENABLED);

//工具栏窗口。在任务栏上没有程序显示,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);

//添加标题栏

::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);

//取消标题栏

::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);

//取消标题栏，保留3d边框，可调整窗口大小

::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); //一定要加这句设置才会立即生效

//取消标题栏和3d边框，保留一个线条的细边框，不能调整窗口大小

::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还要取消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);

//取消所有边框

::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还要取消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向导生成的SDI程序中视图边框的3D效果2010-03-24 17:48先要去掉view的边框，代码如下：

BOOL CSDIView::PreCreateWindow(CREATESTRUCT& cs)

{

cs.style &=~WS_BORDER;//加入的代码

return CFormView::PreCreateWindow(cs);

}

然后在去掉外部Frame的客户区边框，代码如下：

BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)

{

if( !CFrameWnd::PreCreateWindow(cs) )

return FALSE;

cs.dwExStyle&=~WS_EX_CLIENTEDGE;//加入的代码，一定要在CFrameWnd::PreCreateWindow(cs)之后执行

return TRUE;

}
