What I’m trying to figure out is, once the choice is made, for example, you have set the box to ‘ComputerA’, how do you take that value and use it somewhere else?
So, there’s an event you have to attach code to if you want to do something when someone changes the value of the control. Usually, you don’t do that - you just let them dicker around until they hit an OK button, and then you read the values.
To read the value, it’s just $box.SelectedItem.
You also have to distinguish between a ComboBox (a list of values, but the user can type their own) or a simple DropDownList (just a list of values, must pick one). You set a property of the combo box to tell it how to behave. You can do that in the designer.
SAPIEN also runs a great set of forums to help people with GUI issues - drop by there if you need specifics. I don’t use the product every day, so I don’t have all the answers off the top of my head.
