Error Reading Header File When Creating a CIN

Question

Hello everyone. I am a college student new to LabView and Im using the
software to create a real time data acquisition system for EMG signal
analysis for a research project. However, Im having difficulty building
a CIN for my C code. I am using Microsoft Visual Studio.NET 2003 and
running LabView 7.1 on Windows XP. I am using the "Using External Code
in LabView" (April 2003 Edition) manual and I am attempting to do the
steps located in section 3-15 under Visual C++ IDE. However, I keep
getting fatal error C1083: Cannot open include file: 'extcode.h': No
such file or dir. I have followed all of the directions in the manual
and even explicitly tried adding extcode.h to my project  but I
still get this error. My version of Visual Studio is different then the
one described so I was wondering if there is something different that I
have to do in this process. Any help would be greatly appreciated.
Thanks for your time.

Is there a particular reason you're not using a Call Library Function Node to call a DLL instead of using a CIN? Calling DLLs from Call Library Function Node are usually a much more user-friendly process, which I would recommend, unless you need to take advantage of the extra features listed on page 1-4 of Using External Code in LabVIEW.
