Keep tag engine running when LabVIEW exits

[David Moerman]

I have a situation where I'd like to keep the tag engine running even if my DSC application gets shut down, and I don't want to show the shutdown dialog either (I don't want the user to have the option of shutting down). I made sure the "Force Engine Shutdown when LabVIEW exits" flag is off, but this doesn't seem to have any effect. Any suggestions?

David,

did you disable as well the "Show Shutdown Prompt" in the same DSC->Options->Environment tab?

Hope this helps, let us know.

The "Show Shutdown Prompt" is off, because I don't want the user to see the dialog box.

I also should have mentioned above that the tag engine not only stops but also unloads when LabVIEW exits.

This option does not seem to work...

Any response from NI on when/how I could get this fixed?

Currently National Instruments is working on new releases and it turned out that the fixes has been done there.

However, if you want to get it fixed for LabVIEW DSC 6.1 you might get the latest "hot"-fixes from download web site: LabVIEW Datalogging and Supervisory Control Module Version 6.1 for Windows 2000/95/98/ME/NT/XP -- Fixes 
The fixed behavior should be:
If Show Shutdown Prompt is FALSE and :
a. Force Engine Shutdown is TRUE, engine will be shutdown on exit.
b. Force Engine Shutdown is FALSE, engine will not shutdown on exit.

If Show Shutdown Prompt is TRUE and User HAS priviledge to start and stop engine:
Shutdown Prompt
GUI will appear with the default value of Shutdown engine checkbox == Force Engine Shutdown setting.

If Show Shutdown Prompt is TRUE and User HAS NO priviledge to start and stop engine:
Shutdown Prompt GUI will appear with the default value of Shutdown engine checkbox == Force Engine Shutdown setting but it will be disabled.

Let us know, how the fix (see 10. in readme.txt) works out for you.

Hope this helps
