I just upgraded to 7.0 and am trying to use the new ActiveX event structure. I have a call-back .vi that works, but what is the best way to get the event data back to my main program so I can use it? Right now I wired in a control reference as user data and inside the callback wired value(signaling) to this control. Then in my main program I set my event to look for that control being changed. However, I noticed that the sometimes I am getting empty results in the main progam's event structure when the data is allways good inside the callback .vi. Is there a more direct way to have the callback .vi trigger an event in the main aplication?
