I am having a (possibly) similar problem. I opened one of the examples in VS .NET. In the solution properties, I added the path to the include directory (in the C/C++ tab->general tab) and in the fully specified name of the link library (in the Linker->command line tab). I have set Code Generation to multi-threaded DLL debug.
When I compile the program, I get the following:
VC_AcqIntClkDigRef fatal error LNK1104: cannot open file 'nidaqmx.lib'
I can assure you that the path is typed correctly as I cut-n-pasted it from my explorer window. I have enclosed the file name in double quotes.
While I have you attention: is there support for VB.NET along similar lines to the support for ANSI C (i.e., simple header files and link libraries?)
Thanks!
