If you have two forms, FA and FB, then you can directly reference FB from FA and Vice versa. I would suggest implementing method like UpdateCustID(ByVal NewCustID) on FB, which can then be called from FA: load FB FB.UpdateCustID(NewCustIDFromThisForm) FB.Show Unload Me Note that it's not necessary to load FB first - if you reference a form, then it gets loaded implicitly anyway, but I always tend to do so, since makes the code a little clearer "Now I guess I'll sit back and watch people misinterpret what I just said......"
