Hi, I am using TS 4.1.1 and LV 8.6.1 - I would like to be able to use PostUIMessageEx to initiate my LV OI to get operator input and put into a TS variable, after one of several (standard LabView) buttons is pressed on the OI main panel.
My problem is that the OI Event Callback architecture (based on existing OI examples) does not appear to support polling of the OI control values via the control references passed to the callback - polling seems to lock up the OI until the Callback completes so the button state change can't be detected.
However upon receipt of a PostUImessageEx event I am able to pass button references into the callback event case, read the state of the buttons and poke the data into a TestStand variable - the piece that is missing is being able to poll for a button changing state.
Any ideas how to implement this kind of functionality? The only approaches I have thought of is a bit of a kludge - e.g. setting a TestStand variable in my main OI event handler when a button is clicked (ie not via a PostUImessageEx callback) and use some kind of synchronisation trick in the sequence to wait for the TS variable to update.
I need to use PostUImessageEx to set the button labels etc prior to the operator generating a click event anyway, so it would be preferable to set the buttons up, poll for a subsequent click event and then send click data back to a TS variable - all in one callback event. Not possible?
