Can't build the enclosed VI.

[Mark Levine]

The enclosed VI will build and execute but it can't seem to read global variables.  Another program that writes to these globals is running at the same time.

When I run both programs in develop mode everything is fine.

Any ideas?

Thanks,

Mark

You, of course, cannot share global variables between two different exe's. They each run in their own application instance. There are many different approaches to share communication between applications. See this.

Thanks for the answer.  I'm not happy though.

The reason I had to separate the routines is because LabVIEW won't let me open and close subvi windows in an executable.  Something to do with security issues.

I'll read up on the information you pointed me to.

Thanks for saving me time.

Well, the universe displeases a lot of people. It doesn't seem to care too much about us though, as it cheerily goes on its merry way to a nice Big Chill end. I hope it's happy when it gets there.

Can you provide more details on what you are specifically trying to do? Are you talking about problem when getting a reference to an executable?

Never mind.

I've included the subVI in the main program so I don't have to worry about passing globals.

Then I changed the subVI properties to open the front panel when called.  When I did that the executable was able to open and close the subVIs under program control.
