Running a webcam image on a tab in a VI

[cjlandry]

I am trying to run a webcam image on one of the 4 tabs in my VI.  The webcam has its own .exe that I can call in my VI.  If I create a simple VI using a System Exec.VI and then give this the path to the webcam execuable, the program launches and the image from the webcam can be seen.  Great...I want this to happen.  Now, I want to place that image on one of the 4 tabs I am using in my VI but I can't figure out how to do this.  Any help is greatly appreciated.

Unless this application that you launch has an ActiveX Control interface then you won't be able to directly embed its output into a tab or anything else on a LabVIEW VI's front panel. You need to check the documentation for the software that came with your camera to see what you got. Is it a USB camera? If so, you might want to try this.

Thank you for the reply!!  Yes, it is a USB camera and I have downloaded the driver.  Now, it looks like the requirement to use this feature is Vision Assistant 7.1 or higher.  Is this correct?

Thanks again!!

To be honest, I don't know since I've never used the software. I just know that NI provided it after a number of people were asking about interfacing USB cameras to LabVIEW. I'm also not sure of its compatibility with LabVIEW 8 and above.

Did you check to see if the manufacturer for your camera provided any other software?

The easiest way:  Set the Web cam exe window as a child window of your front panel window.
