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

Please find *.sdf file (Intellisence database cache) in project directory and delete it and relaunch project solution this will bring back your intellisence.

Answer 2

There are a couple of threads about similar problems: click on Help at VS2010 and look for Intellisense.

stdafx.h should be added automatically when you create a New Project.

From the file:
// stdafx.h : include file for standard system include files,
// or project specific include files that are used frequently, but
// are changed infrequently

Answer 3

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.

Answer 4

I got it solved by the Microsoft team at http://connect.microsoft.com/VisualStudio/feedback/details/652838/intellisense-not-creating-ipch-folder

It had to do with a certain Windows Update installed on WinXP. The solution was to install VS2010_SP1 and then a certain update over it.

Answer 5

WIN32;_WINDOWS;_DEBUG;Append _DEBUG; remove Append _DEBUG;

Answer 6

IntelliSense stores it's data in the SQL Server, which is installed during VS2010 setup. I recommend you check if the SQL Server Service is running.
