Question

I would like to enable the IntelliSense auto feature (like the Visual Studio C# 2008 Express) but I am using Visual Studio C++ 2008 Express Edition and in the Tools > Options > Text Editor > C/C++ (there is no option IntelliSense (like Visual C#). How do I get this feature enabled? I know I can get a shortcut in place (CTRL-space etc...)? But how do I get it automatically (the drop down menu)?

Answer 1

In C++, IntelliSense is turned on by default (and AFAIK there isn t even an official way to turn it off). However, when you re coming from C#, you might think it s turned off, because it s so much less powerful in C++. (The reason for this is that C++ is much, much harder to parse. You can find more information on the subject here and here.)

Visual Assist improves C++ considerably (although it might not be all that considerably when you re used to C#), but I don t think you can install plugins in the express edition.

Answer 2

This should be enabled by default. But sometimes for C++ projects it stops working.

Is there a .NCB file in your project folder? If so, close your solution, delete that file, and then re-open your solution and do a rebuild.

Answer 3

I use VC++ 2008 Express Edition as my primary environment. All I can say is that sometimes Intellisense works wonderfully, sometimes it doesn t work at all. The Intellisense parser seems to be slow as can be and stumbles over a lot of cases, especially when templates are involved. Sadly, I just don t think you can count on it being consistently available.

Answer 4

One thing that sometimes helps when intellisense doesn t do what it should, is to delete the .ncb file in the project folder in order to force VS to rebuild the internal database (close VS before deleting the file).
