Please point me which is the best ways. Now, i operate in a Product file FORM. Before the user add a new product record, I must know the supplier code first. I want to know which is the best way to do that : 1. To do another FORM for entry the suppler code. (**but i feeling too much work on it) 2. Show up a CONTAINER ( Visible=.T. ) let the user input the code number, then make it hide. (**but i can't make it as MODEL, cause i don't want the user jump to another place at that moment) 3. Active a window (it's defi before), use READ MODEL to get the value. (**but it's not in beautify) Maybe you can tell me another ways to do that.
