Why are functions that belong to a class not showing in Visual C++?

I'm using Visual C++ in Visual Studio 2010 Express, and in the past I remember when you use a string object and after the dot (eg: .) all the member functions will show in list, but that's not happening.

string myString = "hello world";
myString.

After typing the dot, all functions that are part of the string class don开发者_如何学Python't show. Where in Visual C++ is the setting to make them show?

The functionality you refer to is called IntelliSense in Microsoft-speak, their version of autocompletion for variable names, functions, and methods.

IntelliSense is not supported in Visual Studio 2010 for C++/CLI projects. You will only get IntelliSense for projects written in native C++ code. This is explained in more detail here on the Visual C++ Team Blog. There is also a bug filed on Microsoft Connect; the official word is this:

Thanks for your feedback. Unfortunately in this release we had to cut the intellisense support for C++/CLI due to time constraints. If you want to get some intellisense like quick info and memberlist on the native classes you can get it by choosing no /clr support in the project properties.

Thank You!

This is unfortunate news for many of us who work with C++/CLI projects, and we aren't left with many options. A question regarding those options has been asked here: What are people replacing the missing C++/CLI Intellisense in VS 2010 with? The summary is people are either going back to VS 2008
(I believe the Express Edition of 2008 is still available for download if you look around), or purchasing third-party software such as Visual Assist X that promises to bring back IntelliSense.

It's worth mentioning, however, that Microsoft does not regard C++/CLI as a "first-class" .NET language. There's little (if any) reason to start new projects using the language. It's designed for interop purposes between native C++ and managed C# applications. If you want to write C++, you should target the native Windows API (create a new Win32 project in VS). If you want to write managed .NET code, it is highly recommended that you use C# instead (that's a different version of Express that must be downloaded separately). The syntax is very similar between C++ and C#, but you will still have to learn the .NET Framework and idioms. Both native C++ projects and managed C# projects have very much improved IntelliSense support in Visual Studio 2010, so you're guaranteed to be much happier with either of those.
