void CTestRdpNECTIDlg::OnConnectedMstscax1()
{
      try
      {
            LPCTSTR lpExecutablePath = L"C:\\Windows\\System32\\notepad.exe";
            LPCTSTR lpworkingdirectory = L"c:\\";
            int n=m_RDPClient.get_Connected();

      }
      catch(...)
      {
            wchar_t buf[256];
            memset(buf,0,sizeof(buf)/sizeof(wchar_t));
            FormatMessage(FORMAT_MESSAGE_FROM_SYSTEM | FORMAT_MESSAGE_IGNORE_INSERTS,
                  NULL, GetLastError(), MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),
                  buf, (sizeof(buf) / sizeof(wchar_t)), NULL);
            AfxMessageBox(buf);
