Ok... I'm new to this so bear with me. I want to create a drop down type list that only comes up when I use a command button. I have seen a program bring up a window (like a message box) with a combo box looking drop down that you can select from. I may be crazy to want to do this, but does anyone know how to make this happen? Also, how can I call the MS Calculator from a program, use it, and take the results back to the program as input? Just go easy one me. I'm a converted MS Basic programmer (self taught many years ago). Thanks!!! Mark
