(Note: This is the same answer, verbatim, that I gave to another poster asking about how to use a vendor's DLL.)
The only answer I can give you is how to
generally use a DLL in LabVIEW. This is done with the Call Library
Function Node function. There is an example that ships with LabVIEW
called "Call DLL" that has many examples of various types of calls.
There are also several articles in the NI KnowledgeBase on calling external code with LabVIEW. I cannot answer how to use their DLL, as you would need to look at the documentation for their DLL.
