elasped time

[tomsch1]

how can i display elapsed time in a case structure??

my vi is a case structure with just the system exec vi and i wish to display the elapsed time or anything else that indicates the system exec vi is running.

Presumably you have System Exec set to wait until finished. In this case you need to have an independent loop that's running in parallel to System Exec to display elapsed time. When System Exec ends then you end the loop. Make sure you don't create a data dependency between the loop and any of the outputs of System Exec. Otherwise the loop will not start until System Exec ends.

you are correct i have the system exec set to wait.

 i still havn't figured out how to do this yet

There are many ways to do this. One way is to use local variables, though that's clumsy. Another is to use notifiers. Another is to use a queue. Another ...

Here is an example using notifiers:

"my.bat" is a simple batch file that simply waits 5 seconds.

I should have said: One way is to use local variables, though that's clumsy, but acceptable - you just need to make sure you don't have a race condition.
