If the user hasn't tapped on the popup trigger, why are you trying to get
its label? Normally, your code responds to events the OS generates. For
example, with a popup trigger associated with a list, you get a
popSelectEvent and respond to that. If you want the label to have an
initial value, use CtlSetLabel() in your MainFormInit(). Since the OS sets
the trigger label when the user selects an item from the list, you don't
need to use CtlGetLabel() -- just look at eventP->data.popSelect.selection
when you get the popSelectEvent.
If your popup trigger isn't attached to a list, explain what you are trying
to do with it and then maybe I'll be able to give some assistance with that.
