View Full Version : Trouble with gain property
February 18, 2010, 08:43:57
I am using a property node to set gain with an integer numeric control. I have an event structure, and one event is a value change in the numeric control. It is set up in the event structure so that live stop is invoked then the gain is set then a live start is invoked. This however doesn't work and always produces an error. I dont know what to do. I want there to be a button that sets the gain for the camera on the front panel. I dont want the user to have to open the video properties box and change the gain through there.

an error message would have been helpful.
You do not need to stop the live video in order to set a gain value. This can be done while the live video is running.
The only situations I know for gain failures are:
- the value is out of bounds of the gain range
- the gain automatic is enabled
- the video capture device does not support gain.
You know, that there is an extra VI for setting these properties? It comes with the IC LabVIEW extension.
