NX locks .dll file after unload

[Suncad]

Hey there,

I have an awkward issue my .NET NXOpen program. After I run the compiled .dll filewhich works as it should, without exception, except I cannot rebuild to make chnages because it is held by NX process.

I do have a function to unload :

    Public Function GetUnloadOption(ByVal dummy As String) As Integer
[COLOR=#73D216]
        'Unloads the image when the NX session terminates[/color]
        GetUnloadOption = NXOpen.Session.LibraryUnloadOption.AtTermination

End Function

And I know NX reads this function (I checked with just-in-time debugger), still after reaching End Module, the only way to recompile is to close and restart NX every time
Same goes with Excel application : in my program, I also open an excel sheet to read values, and close it :

xlWorkBook.Close()
xlApp.Quit()

And I notice excel app never close in Windows process list, it just start a new instance every time I read the .dll with NX.

Any clue anyone on the behavour ?

"AtTermination" means when the NX session terminates, not when your code terminates. I think you'll want to use the "Explicit" unload option. There is some discussion about it here:

Okay option "Immediately" did the trick. Thanks again, what a time saver option
