LaunchExecutableEx execuation time grows with repeated use

[TerryMoss]

Hello,

I have a program where I need to zip files on a repeated basis, every second to maybe 5 seconds on average.

I have an issue where if I use LaunchExecutableEx to run the zip program, the time for LaunchExecutableEx continually rows.  I.e. if I start at ~0.25 seconds, its ~0,5 seconds after 1000 or so repetitions.

Stoping and restarting the program does not correct it, I have to reboot the PC to reduce the execution time.

I tried this with a sampleCVI program instead of the zip program, and it behaves the same.

LaunchExecutableEx ("C:\\Users\\Public\\Documents\\National Instruments\\CVI2015\\samples\\toolbox\\RegEx.exe", LE_HIDE, &pkZipHandle);

I commented out the "RunUserInterface()" from the example program, so it just loads and exits.

I'm really not sure what to think about this.  Is a CVI bug, a Windows 10 bug?

Any comments and suggestions are appreciated.

Hello,

Do you call RetireExecutableHandle() at the end of the execution of the external program ?

Hello,

Yes, I wait for it to finish and then delete the handle.

A colleague suggested running the thread in the main thread using a Postdefered Call.

That seems to show some promise..

Thanks,

Terry

Update, running this in a deferred post doesn't help anything.
