Hi,
I have been asked to develop a simple gui to take readings from an SR830 DSP Lock-In Amplifier via a PCI-GPIB card. As a starting point I have been trying to get one of the example programs that came with the GPIB card to work. I was trying to modify the C examples into a working windows forms gui with Visual C++, but found that I could not get it to work with any of the dll's or obj files (ni4882.dll, ni4882.obj, gpib-32.dll, gpib-32.obj). After a discussion with an N.I. technical support guy I was told that because these libraries are unmanaged, I wouldn't be able to get it to work at all. He advised me to either try programming it in VC# or VB, or in labview. Now, I'm reasonably experienced in numerical programming, mainly in C++, but all this gui and .net stuff is very new to me and I am learning on the job. So please bare with me!
I have decided to try and do this in VC#, mainly because it's a language I want to gain familiarity with. So now, I've started again with a new starting point... trying to get the .NET3.5 VC# example 'SimpleReadWrite' to work. However, when I try and compile this I get the error message below. I have located the NationalInstruments.Common.dll and NationalInstruments.NI4882.dll files and feel pretty confident that somehow I have to reference these as assemblies or something? But I do not have any idea how to do this. Please could someone point me in the right direction, or better still tell me exactly what I need to do!
Thanks (and sorry if I sound like a complete novice... I am!)
Nick
btw I'm using Visual Studio 2008
