Property Node whitepaper

[aderogba]

Is there any white paper on property node similar to this one on control references http://www.ni.com/white-paper/3159/en/. I am running into some problems with image property node and I have not been able to find useful information.

I'm not aware of any whitepapers. Property nodes tend to be pretty straight-forward. What specifically are the problems you are having?

Thanks. That is what I thought too but I have not been able to find any explanation to the problem I am experiencing. I have subvi with a lot of controls,  (all types of controls including two image controls that display live camera view). The subvi is implemented as a pop up; when the pop comes up, if data is passed to the image control, the image control will not update on FP. However if data is passed to the image control value property node then you can see live image update on the image control on FP. I am using LV 2012.

Frankly, that sounds like a problem with the image control itself. Is this control from a LV toolkit? Where did you get it?

Another thought I just had. Is this image control implemented as an XControl? Something I noticed once is that when you write to the terminal of an XControl, LV doesn't actually update the control unless the value has actually changed from the last time it was written to, but writing to the value property node would always update the XControl.

Can you upload your VI?

why don't you try some debugging techniques to see how actually the program is running.you might get some clue.

what i actually mean is using probe or breakpoint to see at what node data is not passing or any other
