Is there a DLL for Ni-DAQmx rather than using the lib file

[adrianm]

I have just started using NI-DAQmx 8.0.

Previously I was using NI-DAQ 6.9.3, this was able to be used dynamic (ie the DLL) or static (linked to the LIB).

As my software has to run on machines which may or may not have the NI drivers installed, I used the DLL method.

Now I have had to upgrade to NI-DAQmx (due to a new piece of hardware), I have found that I can only use the static option (ie LIB).

If I do this, all my users will need to install NI-DAQmx even though 99% will never use this new hardware.

I could create my own DLL which links to the NI LIB, this would take time as I would need to export all the functions exported by the LIB.

What I wish to know is :

Try this:

C:\WINDOWS\SYSTEM32\nicaiu.dll

Hi adrianm-

S R's suggestion to link into the NI-DAQmx .dll "nicaiu.dll" is correct, but it is not possible to distribute the .dll by itself.  The NI-DAQmx driver must be installed in order for devices to work correctly on your deployment systems.

Hopefully this helps-

Is there any documentation of this DLL? Function Prototypes, parameters, etc?

Hi Brian-

Yes, check out the NI-DAQmx C Reference help and the NI-DAQmx header file.  See Start>>Programs>>National Instruments>>NI-DAQ and <Program Files>\National Instruments\examples\ANSI C (or similar) for more details.
