how do I get dataacq.h?

[Vkumar]

Dear Tom,

    I have installed Traditional NI-DAQ7.4.4, still i have same error (dataacq.h missing). Should i install 6.9.3 or 7.4.1?  Traditional NI-DAQ 7.4.4  will not work?

Hi Vishnu,

daacq.h is present in every version of Traditional DAQ; if CVI doesn't succeed in locating it may be due to an incorrect installation of NI-DAQ or to multiple IDEs installed in your system.

As you may have noticed while installing NI-DAQ, it gets installed only in the most recent occurrence of CVI found in the system (e.g. CVI 2009): if you happen to develop your application with a previous version still present in the same system (e.g. CVI 8.5 or previous one) you will need to copy the installation of NI-DAQ from the newest IDE to the older one you are using.

If this is your situation please let me know so I can list you the files to copy from one version to the other one.

Hello,

I have the CVI version 8.5 installed in my computer and I need to compile a file with the dataacq.h but reference errors keep happening so I think I need some files from this version. Could you please tell me what should I do to solve this problem? Thank you

Priscilla, as you may have read in this discussion, if you need to compile with dataacq.h file it means your program is using Traditional NI-DAQ driver tointerface wih some data acquisition board. Install this software in you PC confirming to install support for CVI and then try compiling your code.

I have a old code to compile and it was wrote with traditional Ni-Daq but today I have just the new one in my computer so I would like to received the files that I should copy to make this work, please. As you said:

If this is your situation please let me know so I can list you the files to copy from one version to the other one.

Could you list this for me, please?

Thanks

I have the 8.5 version in my computer

That sentence you quoted was intended in the case you have installed more than one version of CVI and want to copy an installation of Traditional NI-DAQ from the newest to the older one. In your case the best solution is to download and install Traditional NI-DAQ or find it in some CD you may have in your office.

In case you want to donwload it, Tom gave the link in his answer in this discussion.

Oh..Ok! I understand now. Just one more question: is there this dataacq.h in the newest version (2009, I think)? my boss has this CD so I could solve my problem if that's the case.

As far as I remember neither Traditional Daq nor DAQMx are included in CVI disks, so unless you have a separate disk for Traditional DAQ or an old NI-DAQMx disk that includes that software or you have bought a Developer Suite you will need to download it from NI site.
