DAQmx is not member of NIDAQmxCAPI in Visual Studio 2008

[bwang78]

Hi all,

I am converting code from Visual Basic 6.0 to Visual Studio 2008. I have included a reference to the NIDAQmxCAPI into the VB project.

I get the following error:

"DAQmx is not member of NIDAQmxCAPI"

Here is a snippet of the code that causes the problem but the same thing appears in other places as well

'Create the DAQmx task.

DAQmxErrChk(NIDAQmxCAPI.DAQmx.DAQmxCreateTask("", taskHandle))

I was wondering if anyone would be willing to give me some suggestions on what to do?

Thanks!

Hi BWang78,

If you're working in VB or VB .NET, why are you referencing the C API? This sounds like you may be looking at an example from the ANSI C folder- you may have better luck looking in the example folders listed here, that are designed for use in the language you're using.

Hi Kathryn,

Thank you for your suggestion! 

I am now converting VB6 to VS2012 instead.  The examples in 

C:\Users\Public\Documents\National Instruments\NI-DAQ\Examples\DotNET4.5

are useful!

Besides,

1. I changed target framework from ‘.NET Framework 2.0’ to ‘.NET Framework 4.5’

2. I added "National Instruments Common" and "National Instruments DAQmx" as the references.

It works now.
