Searching the LabVIEW Help for "Task
Creation and Destruction" (without the quotes) will turn up a page that
explains when LabVIEW automatically cleans up DAQmx tasks.
DAQ
Assistant express VIs rely on auto-cleanup, but they don't leak
thousands of tasks because they use a LV2-style global to reuse the
same task for each call. To see exactly what an express VI is doing
behind the scenes, right-click on it and select "Open Front Panel" from
the context menu. This converts it to a normal VI, and then you can
look at the block diagram.
Thanks so much Brad.. I think this gives me a very clear picture..really thanks a lot both of you..
