niDmm include .h files

Hi,

 

I'm writting an application for niDMM. The system has an Mseries DAQ, switching matrix and a DMM. I have been able to integrate the switch and DAQ module within a C code. However, I am having a lot of problems with the dmm.

 

With the standard NIDAQmx.h header I can controll the DAQ and switching modules. For the DMM, I'm using the nidmm.h and the compiler crashes when it goes through thr typedef directives of the vi.h header files.  It seems I need the visa.h and vpptype.h header files, which has not been installed.

 

I would like to know, basically, what header files I need to use to write a C++ application for the DMM PXI-4072

 

regards,

David
