Computer doesn't shut down after data acquisition

[dsavir]

Hi all,

We have software that performs data acquisition and analog output using Data Translation boards. At all our customers, if they ran this data acquisition, when they want to shut down the computer  (after closing exiting our program, of course) it looks as though everything is fine but the screen "Windows is shutting down" just stays there.

This does not happen on the developer computers, only on customer and testing computers. This does not happen if customer just opened software, looked at some files and quit the software. Only after running the data acquisition. Does anyone have any idea how to solve this?

Thanks,

Danielle

I would guess that you are not closing a ref to a program outside of your code that is not allowing Windows to shut down.

Danielle,

I agree with what Tim said.  Something else to check is how are you handling the drivers for the Data Translation boards, i.e. are you closing a clearing all of the calls to the dlls.  I would also try using the NI I/O Trace to see if everything is being closed are if you are still communicating with a device.

If all else fails, you could always force Windows to shutdown.
