What is a good naming convention for vars, methods, etc in C++?

I come from a the Objective-C and Cocoa world where there are lots of conventions and many people will say it makes your code beautiful! Now programming in C++ I cannot find a good document like this one for C++.

http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/CodingGuidelines/CodingGuidelines.html

Standard C++ probably does not have something like above but I hope I can stick to some other SDK or APIs (like Microsoft's(?),etc) conventions.

I hope you can provide me with some links.
