sequencial execution of two VIs in LabView

[jianglai]

Hi, I am sure other people have encountered the similar problem, but I can not seem to find relevant posts on the NI forum. I have two VIs.  I like to execute one VI first (which is a while loop), and a second later execute the 2nd VI.  Since the first VI runs "forever", the 2nd VI would never get executed if I put the two VIs in a sequence in a main VI. What is the best way to do this? I apologize for the newbie question. Best regards,Jianglai

This thread will give you some info. Beyond that we will need more details to give you a useful answer. Mike...

You can use queues or notifiers to do this. Here's an example using notifiers that runs a second vi once after the first vi has run in the loop. See the Master/slave or producer/consumer design patterns (they are included in the LabVIEW templates) if you need to run the second vi more than once.

The simplest would be to just do something like in the image below. It would help if you could provide some more details though.&nbsp;<img src="Loading Image..." border="0" width="289" height="102">&nbsp; Message Edited by Dennis Knutson on 08-14-2008 09:04 PM
