1）窗体全屏

bool m_bFullScreen=true;//!m_bFullScreen; // 设置全屏显示标志
//一种更好的全屏显示
LONG style = ::GetWindowLong(this->m_hWnd,GWL_STYLE);
if(m_bFullScreen)//全屏显示
{
style &= ~(WS_DLGFRAME | WS_THICKFRAME);
SetWindowLong(this->m_hWnd,GWL_STYLE, style);
this->ShowWindow(SW_SHOWMAXIMIZED);
CRect rect;
this->GetWindowRect(&rect);
::SetWindowPos(this->m_hWnd,HWND_NOTOPMOST,rect.left-1, rect.top-1, rect.right-rect.left + 3, rect.bottom-rect.top + 3, SWP_FRAMECHANGED);
}
else
{
style |= WS_DLGFRAME | WS_THICKFRAME;
SetWindowLong(this->m_hWnd, GWL_STYLE, style);
this->ShowWindow(SW_NORMAL);
}

2）Activex窗体全屏

bool m_bFullScreen=false;
HWND m_hWndParent;
void CFfDlg::OnLButtonDblClk(UINT nFlags, CPoint point)
{
    CDialog::OnLButtonDblClk(nFlags, point);

    m_bFullScreen=!m_bFullScreen; // 设置全屏显示标志
     //一种更好的全屏显示
    LONG style = ::GetWindowLong(this->m_hWnd,GWL_STYLE);
    if(m_bFullScreen)//全屏显示
    {
        //用MFC隐藏系统任务栏
        CWnd * wnd = FindWindow("Shell_TrayWnd",NULL);
        wnd->SetWindowPos(NULL,0,0,0,0,SWP_HIDEWINDOW);

        m_hWndParent=::GetParent(m_hWnd);
        ::ShowWindow(m_hWndParent,SW_HIDE);
        ::SetParent(m_hWnd,NULL);
        style &= ~(WS_DLGFRAME | WS_THICKFRAME);
        SetWindowLong(this->m_hWnd,GWL_STYLE, style);
        this->ShowWindow(SW_SHOWMAXIMIZED);
        //CRect rect;
        //this->GetWindowRect(&rect);
        //::SetWindowPos((this->m_hWnd,HWND_NOTOPMOST,rect.left-1, rect.top-1, rect.right-rect.left + 3, rect.bottom-rect.top + 3, SWP_FRAMECHANGED);

        int   nScreenWidth=GetSystemMetrics(SM_CXSCREEN);
        int   nScreenHeight=GetSystemMetrics(SM_CYSCREEN);
        ::SetWindowPos(this->m_hWnd,HWND_NOTOPMOST,0,0, nScreenWidth,nScreenHeight, SWP_FRAMECHANGED);
    }
    else
    {

        //用MFC显示系统任务栏
        CWnd * wnd = FindWindow("Shell_TrayWnd",NULL);
        wnd->SetWindowPos(NULL,0,0,0,0,SWP_SHOWWINDOW);

        style |= WS_DLGFRAME | WS_THICKFRAME;
        SetWindowLong(this->m_hWnd, GWL_STYLE, style);
        ::SetParent(m_hWnd,m_hWndParent);
        ::ShowWindow(m_hWndParent,SW_SHOW);
    }
}
