API or VISA?

[orchid]

I want to capture raw EEG data on the labview platform. The sampled data is encoded using Flexcomp encoder (10 channel) and transmitted to the software via optical fiber, connected to the TT-USB interface unit, which converts the light into USB serial data. I am using TT-USB to interface with labview 8.5.  Actually, I want to use NI-VISA, but the company was suggested to use DLLs (API) to manage the data capture and processing. Because of the uncompatiblity of visual C++ 6.0 with vista, now I am going to use Microsoft Visual Studio 2005.

Actually, I do not have any idea how to start.Can you give me an idea of it?

If you use a dll, you could use a Call Library Function Node.  You can pass the appropriate parameters and obtain returned values.  Very similar to calling a function in C.
