    how about specifying a connection string with DOS commands?
    currently our username and password is hard-coded in the batch file and we want to avoid that.
    Thanks in advance!


    I have to say, every time I come to you have another remarkable post to read. One of my friends was talking to me about this topic a few weeks ago, so I think I’ll e-mail my friend the url here and see what they say.
