Hi! Please help me.

I am now developing a GUI which allows the user to select an item (a value) out of some items listed in ComboBox (there are two ComboBox actually). Once the user has selected the item(i.e a value or number), I need to make use of the item and manipulate on it such as transmitting the item using serial port etc. The problem I am facing is I don't know how to get the values the user has selected and transmit it.

Please help me out. Thank you.
