This question actually is an implicit answer, since I could fix the problem in the meantime for myself. But I wanted to publish my experience, since some other developers might have a similar problems.
The problem:
I am using VS2010 prof SP1 on Windows XP SP3, pure C++ only. (AntiVirus software present). Since some days Intellisense - which is quite helpful under normal conditions - does not work anymore.
Things tried:
- created a new simple console application. -> Intellisense still not working.
- resetting VS-Settings by means of Tools/Import & Export Settings/Reset. -> Intellisense still not working
- Changes to option settings in Text-Editor/C++/Advanced inclusive logging did not help. -> Intellisense still not working
There was actually an interesting observation:
Intellisense normally creates a directory 'ipch' in the solution directory to store intermediate files. In my solution folders it disappeared as soon as the solution was opened. When I created a folder 'ipch' and opened the solution Intellisense removed the folder again - strange.
The final fix:
During the last week some new Windows updates were installed. I noticed some other unusual behaviour of my PC as well. After having created an image of my PC, I decided to uninstall Windows updates from 2013-09-11 (4 packages) and one update from 2013-08-28. (unfortunately I did not note down the KB-numbers)
AND: out of a sudden Intellisense is working again !
Maybe this report could be helpful for some other persons. Automatic Updates are now disabled on my PCs.
Confirmed 100%
Microsoft Visual Studio 2010 Version 10.0.30319.1 RTMRel Microsoft NET framework 4.0.30319 RTMRel
Microsoft Windows XP Professional Version 2002 Service Pack 3
Intellisense stops working after installing KB2876217.
Intellisense is back after removing update.
I had the same problem and also had the idea that one of the Windows Updates is buggy, so I can confirm your report.
I tried to uninstall them one-b<-one and found the "bad guy":
KB2876217 destroys intellisense for VS2010 under XP SP3.
A supported hotfix is available from Microsoft to fix this issue. Check at http://support.microsoft.com/kb/2526044/en-us
Actually, it may not be such a good idea to uninstall update KB2876217. Instead, install Visual Studio SP1 update (if not already installed) and then install update KB2526044. I have tried it before and it does work...
