How to make DLLs independent

[Dynamik]

Greetings!,

      I want to use a DLL to encapsulate some LabVIEW code so the DLL and caller can be updated independently.  However, there are some utility VIs used by both the caller and the DLL.  After the DLL is compiled, if the utility VI changes in the caller, it breaks the DLL.  If the utility is changed in the DLL, the caller loads first, and it breaks the DLL.

Is use of unique-names the only way to cure this behind-the-scenes dependency?  I was hoping for some compiler option, but don't see one.

Thanks.

Yes unique names is the only easy way. In LabVIEW 8 you could also try to fiddle with the contextes to get the DLL code to execute in it's own application context but that is probably a bit of a hassle.
(Or you could create the DLL in a different version than the LabVIEW version your want to call it from. Then the DLL is most probably even running in its own runtime process 😉

( lol,  me thinks you're reading too many threads ;^)  )

Thanks Rolf.

Unique-named everything ( would like to see a compiler option to do this...)

There are several project renaming tools floating around. You can probably even use OpenG's mangle\unmangle name VIs (in the app control palette) for automating it somewhat.

I have now the same problem and I posted here:
