The reason why no video is showing up is probably because the update speed of the front panel is quite low. This is because everytime, the complete front panel is being update, rather than only the video. You will probably need to find a faster way of publishing the video is you want to view it remotely.
I suggest to check out the following article in the NI KB, it list several possibilities with their advantages/disadvantages.
Is LabVIEW in the newest versions really publishing the contents of ActiveX and .Net controls to remote front panels? Because this was the reason in the past that those controls appeared blank on remote front panels.

and can any 1 tell me is it possible to capture a image using ActiveX.
Hi McArthur and anyone else who may be able to answer this questio.
Firstly thanks for the program. its great. Can it be adapted to access two webcams simultaneously? if so how?
I have tried this program, however when I run it it can execute my webcam (as the light turns on) but no image is shown.
I didn't notice the date of this posting until now but I took the liberty of rewriting this code to introduce some style concepts that may help new developers
