        Private Sub SetConnectionInfo(ByVal table As String, _
           ByVal server As String, ByVal database As String, _
           ByVal user As String, ByVal password As String)

           Dim logOnInfo As New TableLogOnInfo()
           logOnInfo = Report.Database.Tables.Item(table).LogOnInfo

           Dim connectionInfo As New ConnectionInfo()
           connectionInfo = Report.Database.Tables.Item(table).LogOnInfo.ConnectionInfo

           connectionInfo.DatabaseName = database
           connectionInfo.ServerName = server
           connectionInfo.Password = password
           connectionInfo.UserID = user
           Report.Database.Tables.Item(table).ApplyLogOnInfo(logOnInfo)
