Answer 1

string str = Utils.DataConnString;
                string pat = @"(initial catalog=(?<m>\w+);)";
                Regex r = new Regex(pat, RegexOptions.IgnoreCase);
                txtDatabase.Text = r.Match(str).Groups["m"].Value;                pat = @"(data source=(?<m>\({0,1}\w+\){0,1});)";
                r = new Regex(pat, RegexOptions.IgnoreCase);
                txtIp.Text = r.Match(str).Groups["m"].Value;                pat = @"(user id=(?<m>\w+);)";
                r = new Regex(pat, RegexOptions.IgnoreCase);
                txtUserName.Text = r.Match(str).Groups["m"].Value;                pat = @"(password=(?<m>\w+);)";
                r = new Regex(pat, RegexOptions.IgnoreCase);
                txtPassword.Text = r.Match(str).Groups["m"].Value;
