Passing LVRefNum types between labview DLL and Teststand

[MN1976]

Hi,

I have a DLL written in labview which passes a LVRefNum out (object reference that contains a handle for a hardware session). TestStand won't recognise this data type and no manner of fettling or adding Custom data types to Teststand seems to work.

It works in CVI fine by declaring a LVRefNum as an u32 via "MagicCookie" in extcode.h

Anyone any ideas?

Anyone? Is there a solution to this or not, seems strange that NI data types in Labview and CVi aren't compatible with Teststand. They're just u32s at the end of the day.

Hi,

I am not an expert in TestStand, but I was looking into this and found a similar forum thread. Although it is from some time ago, it seems to me that it is quite relevant to you still. Check it out here:

I hope this helps.

Kind regards,
