Switching between two webcams on the dashboard

[teku14]

So I followed the instructions and didn't have success although its most probably because I didn't follow the instructions correctly. I'm posting the changes I made below and maybe you could point out where I went wrong.

Starting with the robot code, If I understand this correctly, the Camera Background VI just houses the Send 2 PC VI and you can ignore everything else if the camera is run over USB. So the first thing I did was make a modified version of the Send 2PC VI or as its called WPI_CameraSend Images to PC VI.

In it, I the changed the port number constant wired into the TCP Listen VI to a control named "port". This was originally just set to 1180. Then I changed the Image Name Constant going into IMAQ create VI into a string control as well whereas it was originally the WPILib_SendtoPCImage you were referring to.

I named this VI as "Sketchy Send 2 PC" just to keep track of changes but you can see that I placed this directly onto the vision processing VI.

Originally the set of set up VIs associated with "USB 1" was not there as shown below. I just branched the single original camera reference into to two separate "Sketchy Send 2 PC" VIs while maintaining the same parameters that you see in this image being 2 different port numbers 1180 and 1179 (I'm not very familiar with so I just used 1 number less thinking it to be legitimate) and then "WPILib_SendtoPCImage A" and "WPILib_SendtoPCImage B" for the two VIs Respectively. When this, along with the other changes didn't work, I made the change that you see in the image where I'm opening two separate Camera References.

Next in the Dashboard, I made the following changes:

Starting from the Camera Loop (Loop #2) and going further in

Essentially, Just modifying each concentric VI to change the 1180 TCP port constant at the bottom most level, to something that I can change on the dashboard while its running.

At the end of this, I the code is still able to recognize and display one USB camera but cannot change the display to the second one whenever I bump the port number on the dashboard (while its running) between 1180 and 1179. It just stays on the same original camera. I cannot tell which camera I have assigned port 1180 or 1179.
