Hi all

I have a back-to-back TriggerEvent call in a control. It looks like this:

TriggerEvent('ue_event_1')

TriggerEvent('ue_event_2')

I need to get the ue_event_1's return value to determine whether or not to execute TriggerEvent('ue_event_2').

If I do this

ll_return_code = TriggerEvent('ue_event_1') the returned value is that of the TriggerEvent, not of the ue_event_1.

Is there a way to get the the returned value of ue_event_1 in the circumstance?

Thanks!

There is a different syntax that you need:

return = objectname.Event eventname(arguments)

Look in the help file for this topic:

Syntax for calling PowerBuilder functions and events

Hi CJ;

Roland is correct. You are using the original PowerSoft calling method as defined in PB version 1.0. This was updated to the newer syntax that Roland is alluding to in PB 5.0.

The return from TriggerEvent only indicates whether it was able to trigger the event. TriggerEvent is should only be used when the name of the event is in a string variable and there are no returns or arguments.
