Depending on how concerned you are about security, you might want to take

into

consideration that a login box popped up on the default desktop is

incredibly vulnerable

to several password-snarfing attacks (I once wrote one of these in under

ten minutes

during my security course).

CLoginDlg login;
if(login.DoModal() ==IDOK )
{
m_pMainWnd->ShowWindow(SW_SHOWMAXIMIZED);
m_pMainWnd->UpdateWindow();

// In an SDI app, this should occur after ProcessShellCommand
return TRUE;
}
