Auto Completion in VS 2010

I'm currently trying VS2010 and while it's smooth, good looking, sexy would I even add, I've met a MAJOR Turn off, being still a big teen noob in C and C++, I need my AUTO Completion until I learn some of the lib's members.

I tried toggling the CTRL+ALT+SPACE Option, using the hotkeys, the Button in the EDIT Tab is disabled (grey) And LASTLY I tried it using the command but got a message say开发者_Go百科ing that it's disabled. It works in other languages.

This blog post explains how to disable it ... perhaps you can use it to reverse the process? If you would like to see how nice VS2010 intellisense for C++ is compared to 2008, take a look at http://www.msteched.com/2010/NorthAmerica/DEV316
