Description

This behaves similarly to official, with the only difference it uses a shared method in CServerDlg (etc.) to construct the connection string from members of CServerDlg (etc.), whereas officially it accesses this externally, e.g.:

CString strConnect;
strConnect.Format(..., m_pMain->m_strGameDSN, ...);
