Calling and Running an exe in background

[Swathi]

Thanks Paul for your inputs.

Currently, we have Viewpoint application running in the background and then 
we start our Eprime experiment. With in the Eprime I have an inline code 
calling the Viewpoint DLL to start recording the eye movie and stop once 
the experiment is finished.

But we would like to open and close viewpoint application automatically via 
Eprime so that we dont loose time in between our scans.

Suspend and resume example, as I mentioned earlier does not serve this 
purpose.

Meanwhile, I will look into the COM interface option via Viewpoint and your 
previous post about matlab.

Thanks again,
Swathi
