How to search DAQ card programmatically using Visual Studio 2008

[mkc]

I try to use Visual Studio 2008 to discover NI DAQ card connected in a system programmatically using NI VISA. I do so by running the example program provided in NI VISA installation (C:\Documents and Settings\All Users\Documents\National Instruments\NI-VISA\Examples\DotNET3.5\FindResources\cs). I am surprised the result doesn't show the connecetd NI-9233. In addition, I do not see relevant IO transaction in NI Spy also.

May I know how to discover DAQ card connected to a system programmatically using Visual Studio 2008, without using LV and Measurement Studio?

Hi mkc,



Whatever you try to do with DAQmx device, you must use DAQmx function, not VISA.

You may refer to http://digital.ni.com/public.nsf/websearch/AE521D8AEFD27E1E86256F9F007DF570?OpenDocument.

It shows property to determine DAQ devices in the system.

Hi Kate,

Thanks. I just found out an alternative too. Use NationalInstruments.DAQmx.DaqSystem.Local.Devices to retrieve a list of DAQ device name, then use DaqSystem.Local.LoadDevice(deviceName) to retrieve device information e.g. serial number and bus type.

Regards,

MKC
