Intellisense in vs2010 with c++

Question

I can\'t get intellisense to work. Even if I start with an empty project and add just one file to it with only an include for iostream and an int main()

Answer 1

I thought I should mention this:

In Visual Studio 2012 I noticed that Intellisense suddenly stopped working in my C++ project (same error as the poster described). This happened because I had added "DEBUG" as a Preprocessor definition under Project Properties -> C/C++ -> Preprocessor.

Once I removed it from that list and instead put it in the code ( #define DEBUG ) intellisense suddenly started working again.

I don't know why this happens, I just know it screws up my intellisense. I hope this helps someone.
