systemexe.vi

I am using system exe to run a batch file but just wondering how my labview program knows that all the command in the batch file is finished? I want the batch file to end before I do somethings else.

thanks

There is a "wait until completion" input to the vi and its default value is already True.
So you don't need to do anything special.
Or maybe you are interested in HOW this works? I don't know, but I guess it is based on finding the console window by title.
Another possibility: If the batch is run as a child process, its status can be checked by the parent.

You did answer my question. That was exactly what I asked. Thank you very much, Paolo. I appreciated it.

Also, if an executable, which returns a value, is called by SysExec.vi, the value can be passed to the LV vi.  THis is especially useful to find out the status of the executable. Or to select an appropriate error message.
