Thanks Paul for your inputs.<div><br></div><div>Currently, we have Viewpoint application running in the background and then we start our Eprime experiment.

I don't think it would be possible to call DLL functions that use graphical devices in any way, so that may limit your options. Note that running an application is not the same thing as calling a DLL function, so I'm not sure how viewpoint could be integrated. I think there are application suspend and resume examples available on the PST support site that could be used as a starting point if you're integrating a regular application instead of a DLL. If the viewport application (or DLL) supports COM interfaces, that would also be an option. (See one of my previous post on interfacing with matlab.)<br>
