x,
Opening a VI from within a CIN can be done exactly the same way it would be done if the CIN were the top level program and LabVIEW was only a part of it. If you have done any ActiveX programming, this would be the easiest route. Another method would be to create a DLL out of the VI that you want to call and call it from the CIN that way. Lastly, if you need to just launch a VI, you could return out of the CIN with a VI name to run and then put yourself back into the CIN again with a special flag to pick up where you left off.
