Using GPIB with VB.NET

[Techmanbd]

Ok, I have searched all over for this answer and no answers, that I can find are out there. I have emailed NI service and the only answer I get is sign up for beta in .net, but so far they have'nt activated me for it yet and I need to get this project done. And I need to be able to talk to GPIB using VB .NEt. I just bought this card and i don't have the budget to go and by the Measurment Studio. ALl I want to be able to do is to communicate with a Multimeter from Agilent like I use to be able to with VB 6 and the use of the MODULES THAT CAME WITH IT. I read you can access the DLL's directly, But what DLL's and the commands to access the dll to get my info

This kind of questions are sometimes posted. To use GPIB from .NET managed environment, the easiet way is use VISA COM software. The VISA COM software is available on every PC which installs NI-VISA 3.0. I posted a C# example using VISA COM at the following post. Basically the approach is the same for VB.NET and VC++.NET.
