Re: Any way to have an MFC app handle multiple physical displays?

This code will make a dialog span across all the monitors;

class CMyDialog : public CDialog
{
......
private:
   static CRect m_MonitorRect;
   static BOOL CALLBACK MyInfoEnumProc(HMONITOR hMonitor,HDC
hdcMonitor,LPRECT lprcMonitor,LPARAM dwData);
};

CRect CMyDialog::m_MonitorRect;

BOOL CMyDialog::OnInitDialog()
{
......

   EnumDisplayMonitors(NULL, NULL, MyInfoEnumProc, 0);
   SetWindowPos(NULL,m_MonitorRect.left,m_MonitorRect.top,m_MonitorRect.Width(),m_MonitorRect.Height(),SWP_NOZORDER);
   return TRUE; // return TRUE unless you set the focus to a control
}

BOOL CMultiMonitorDlgDlg::MyInfoEnumProc(HMONITOR hMonitor,HDC
hdcMonitor,LPRECT lprcMonitor,LPARAM dwData)
{
   CRect Rect(lprcMonitor);
   m_MonitorRect.left = min(Rect.left,m_MonitorRect.left);
   m_MonitorRect.top = 0;
   if (m_MonitorRect.bottom == 0)
   {
      m_MonitorRect.bottom = Rect.bottom;
   }
   else
   {
      m_MonitorRect.bottom = min(Rect.bottom,m_MonitorRect.bottom);
   }
   m_MonitorRect.right = m_MonitorRect.left + m_MonitorRect.Width() +
Rect.Width();
   return TRUE;
}
