Is Imports NationalInstruments.DAQmx still the first statement in a VB2010 programme?

[jeffrey123]

I had good results with VB2005 and WindowsXP but having upgraded to Window7 We need to use VB2010 to operate the USB6008.

When I type Imports NationalInstruments.DAQmx at the very top there's a sqiggly underline in green with pop-up to the effect that this is the wrong Namespace or the file cannot be found.

I remain in due course corrected please.

Hi,

You need to add a reference to the DAQmx library.

Thanks for your reply.

I have made reference to:

CW3DGraphLib

MXCTRLib

NI.Common.Native

NI.MStudioCLM

NI.NiLMClientDLL

NATUPNPlib

NIDAQmxCAPI

NIReports

nisysapi

Still the sqiggly green line under NationalInstruments.DAQmx

Does this list at least contain the correct reference?

Maybe I must change something in the Properties Window?

Look forward to your reply Sir

Hi,

You should see the NationalInstruments.DAQmx NET library listed. See attached image.

When you installed the NI-DAQmx driver software, was Visual Studio 2010 already installed?

If not, you may need to go back to and repair the install or re-install of NI-DAQmx to add support for .NET 4.0

I only have VB.NET 2010 Express. Once I added the reference to NI-DAQmx, C:\Program Files (x86)\National Instruments\MeasurementStudioVS2010\DotNET\Assemblies\Current\NationalInstruments.DAQmx.dll, everything was fine.

Thanks for telling me that information.Vital.Problem solved.

Maybe you can tell me that the DLL is the same one I had success with on VB2005 and that all the statements relating to the USB 6008 are the same.Once again many thanks

Hi,

You should post some of your code. It looks like you were using Measurement Studio 6.0 Active X controls.

The code for .NET calls to DAQmx will be different.

Well I managed to make reference to 

NationalInstruments>DAQmx  and

NationalInstruments.Common.

and no errors in the editor till i build then:

"The referenced assemblies could not be resolved because it has a dependency on System Web Version 4 .0.0.0 which is not in the currently targeted frame work .NET Framework Version 4.

After the build all squiggly green underline back by NationalInstruments.DAQmx..

I installed .Net Framework 4 after i installed VB2010.

Dear Curt,

Do you have any idea?

regards

jeff

Please see the comments I made above

I referenced NationalInstruments.DAQmx  and

NationalInstruments.Common

and the squigtgly green line under NationalInstruments.DAQmx goes away.

but when I Build it comes back with the msg

"The referenced assemblies could not be resolved because it has a dependency on System.Web Version 4.0.0.0

which is not in the currently targeted framework  .Net Framework 4...."

Do you have any ideas

regards

jeff

Hi Jeff,

The System.Web reference could have been added by any number of components that you included in your project. Did you add a Measurement Studio 'NetworkVariableDataSource' or 'NetworkVariableBrowserDialog' your project?
