Calling LabView DLLs from C/C++

[Hans Forssell]

Hi!

Is it possible to call functions in the LabView DLLs directly from
C/C++?
Functions like InvChiSquare in lvanlys.dll has "Adapt to Type" void *
parameters. How do I specify those parameters from C/C++?

I have tried to use the "Build Shared Library" function in LabView to
make a wrapper dll of the "Inv Chi Square Distrubution" vi, but when I
call this function in the dll from C/C++ the function never returns.
Other functions in the same dll that does not use functions in the
lvanalys.dll are working ok.

Regards

There are 2 great places to get infomraiton on passing data to dlls, and the data types used. First would be this manual. Using External Code in LabVIEW

The second is the dll examples that ship with LabVIEW 7.0. Go to LabVIEW 7.0\examples\dll\data passing\Call Native Code.vi
