修改窗口STYLE属性

 

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);
