怎么将视图全屏显示

如何将视图全屏显示
我建立了一个单文档MFC应用程序，为了将视图全屏显示，我去掉了标题、菜单、工具栏、状态栏和边框。代码如下：
int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
  ..........//省略
ModifyStyle(WS_CAPTION,0); //去掉标题栏
ModifyStyle(WS_THICKFRAME,0);//去掉边框
  SetMenu(NULL); //去掉菜单
}

BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
if( !CFrameWnd::PreCreateWindow(cs) )
return FALSE;
  //以下为设置全屏显示
  cs.x=cs.y=0; 
  cs.cx=GetSystemMetrics(SM_CXSCREEN);
  cs.cy=GetSystemMetrics(SM_CYSCREEN);
 
return TRUE;
}

运行程序后，发现视图的边界仍有两个像素宽的区域，该区域无法响应WM_MOUSEMOVE消息，同时该区域无法绘图，我觉得该区域不是客户区。我现在希望，全屏幕都可以绘图，可以设置背景颜色，请各位高手指点一下，Thank you very much!

当然不是客户去啦！楼主的问题很典型，这其实是一个微软windows窗口的问题，是窗口就要有窗口区，通过扩大客户去是不能够进行全屏显示的，楼主可以查查全屏技术是如何实现的~~~~~希望对你有帮助！！！

我是全屏的代码

C/C++ code

 void   CMainFrame::OnViewFullScreen()       {     RECT   rectDesktop;             WINDOWPLACEMENT   wpNew;                 if   (!IsFullScreen())             {                     //   need   to   hide   all   status   bars                     //m_wndStatusBar.ShowWindow(SW_HIDE);             //m_wndToolBar.ShowWindow(SW_HIDE);         if(m_wndStatusBar!=NULL) delete   m_wndStatusBar;     if(m_wndToolBar!=NULL) delete   m_wndToolBar;     this->UpdateWindow();             //   We'll   need   these   to   restore   the   original   state.

发现视图的边界仍有两个像素宽的区域是什么意思，显示有东西还是显示正常就是无法响应MOUSEMOVE消息啊？
