Get control of a dropdown box

Does anyone know how to get the controls on a operation drop down box? I need to get the OpCode value from it, and I I can’t figure out what type to use. EpiTextBox, and EpiCombo don’t work. I get an exception that says the OpMasterCombo can’t be cast to type “whatever I try…” Do I need to bring in some other DLL’s for this to work?

(ultimately, I can probably just add the tracker in manually so it’s an actual text box, but that’s just a pain…)


It’s an EpiUltraCombo.
