[C#] Getting the maximum number of physical channels of a device

[JoeKellyATI]

Hello all,

Is there a way to get the maximum number of physical channels (analog in/out, digital in/out) of a connected device?

I have a couple of USB DAQs, one has 4 differential Analog Outputs, the other has 40 differential analog outputs.  I want the ability to make some decisions based on their analog output counts.  Is there a property somewhere in the measurement studio C# library I can use?

Thanks,

Joe

Hi Joe,

I've attached an example program below that uses Microsoft Visual C# to Find all VISA resources available to perform communication. It would be a great place to start looking or even use in your application.

Hi Shane,

Thanks for an answer.  I looked up the program you posted about (Using Microsoft Visual C# to Find all VISA Resources and Perform Communication), and it's very old.  It was developed using VS2002 and I can't find the references it's using.

Thanks for the heads up, but this problem is still open.

Hi Joe,

Do you have NI-VISA installed for .NET? I did a little digging and found that the NI-VISA .NET Class Library lists a Find method that we could use similar to that example. I have included the download link to the latest NI VISA Driver Download as well as the help page for the FindResources Method Below.
