Re: which command I can use to exit from a subvi without exiting from labview in run-time?

In LabVIEW, go to the FIND EXAMPLES menu. View the New Event Handler.VI or the Old Event Handler.VI and either of these will do if this is indeed what you are looking for... =0)

Re: which command I can use to exit from a subvi without exiting from labview in run-time?

Are you trying to exit a subVI to get back to a Main VI? If so, use a simple state machine. There is a template for this in LabVIEW. Put the SubVI inside the state machine to be called. For the subVI, under the VI Property "Window Appearances", customize the window to Show Front Panel when called

which command I can use to exit from a subvi without exiting from labview in run-time?

Similiar to 'Exit Sub' command in Visual Basic.
