I would like to know, how to activate this sensitive suggestion box? and knowing that this visual studio 2010 installed successfully. even know that this sensitive box working in VB forms normally, but Visual C++ not.

Well, that Microsoft quality for you: lot's of features that don't work.
You can try deleting the .ncb file that is located in the same folder as your solution file (.sln) and then reopening the project. Sometimes, with small solutions, that helps. With bigger solutions, just give up. :cry:

but in Visual Studio 2005/2008 work normally:o. just give me steps like: tools->option->general setting-> make some changes->apply->ok. something like this, plz:cry:cry:

In VS 2010 intellisense for C++ isn't really gone or borken in general, it just does only work for native C++, not C++/CLI. Both simple as that and sad but true... :(
