Labview 5.1 Executable crashes when I try to run it a second time

[kbee]

I created an executable from some labview 5.1 code I wrote. The code works fine when I run it under labview, but when I created an executable, the code crashes. I can run the code once and it will work fine, but when I try to run it again it crashes.

The coded basic function is to record data displayed on a network analyzer screen. I have the analyzer go into remote mode for data collection and back to local after data collection so changes can be made to the display. When I try running it again after changes were made, the executable crashes.

Has anyone experience this problem?

I have run into this problem a couple of times for different (but similar) reasons.

One was that I used the VISA open and talked to the instrument, but did not CLOSE the VISA session. When trying to OPEN again (second time program is run), the program would crash.

I had the same problem with opening references once. It is supposed to close all references when the program ends, but I always close my sessions before exiting.

Look for OPEN without CLOSE in the program.

Hope this helps.
