Using IEngine.UnloadAllModules to unload Labview

[CharlieRodway]

Hi,

I currently have a problem with a DLL I'm using.  The problem with the DLL is understood but as it is from a 3rd party vendor it can't be fixed.

The DLL is called from TestStand, via a labview VI.  If the DLL returns an error, it needs to unloaded from memory - either by closing Labview or by selecting "File->Unload All Modules".

I have included a ActiveX step in the cleanup of the sequence which will call Iengine.UnloadAllModules().  This appears to work for this case but is this safe, i.e. affect database/report generation or any other known issues?

I've attached example code, if it helps.

Hi Charlie,

That kind of step in cleanup is fine as long as it is the last step executed. Alternatively you can set the specific step that uses that dll to Unload after step executes. This setting can be found under the Run Options tab in the step properties. This will always unload that module after it executes whether there was an error or not.
