how do I get dataacq.h?

[imanon]

I am trying to work on some LabWindows/CVI code given to me from a prior version of an application I am upgrading. When I try to build, it seems I am missing the "dataacq.h" header in my LW/CVI installation. I have searched for this file and it is nowhere to be found in my installation directory. Is there another code module or instrument driver I need to install? Does anyone know how I get that particular header file? Thanks in advance,

Andy

forgot to mention, I am using version 7.0, whereas the old application was built w/ either version 5.5 or 6.0 of LW/CVI.

thanks, Dave. In reading those links, it looks like I need to load the NI DAQ driver. I guess this is a separate product from LW/CVI & I need to look into either downloading it or buying it, whichever. I assume there is some info on NI's site, I am not familiar with this product and will have to research it further. Thanks again,

Andy

Hi AJ-

The NI-DAQ driver is a free download from www.ni.com. 

All versions of NI-DAQ (including NI-DAQmx 7.4) include the Traditional DAQ API that will install the file you are missing. You will need to make sure that LabWindows/CVI support is installed- this option should be enabled by default, but make sure that the installation directory is the same directory that CVI is installed on your system.

Thanks,

Sounds like a good tip, I will watch out for that.

I am using LabWindows/CVI version 8.0.1 and have downloaded NIDAQ version 8.1.0 but I do not have the file "dataacq.h" anywhere.

Do I have the wrong versions/components????

Hi Bendt-

The information I posted previously is incorrect now; the Traditional NI-DAQ (Legacy) driver is not bundled with versions of NI-DAQmx 7.5 and later.  There is a seperate download available.

Hopefully this helps-

Thanks, Tom W. that works.
