Hi all,

I'm trying to port a C++ project from gcc (on MinGW) to Visual Studio 2010 inside a Visual C++ Windows Forms application. The code was originally written on a Windows XP 32-bit machine. Now it is being ported into a Windows 7 32-bit machine. This project uses quite a few boost libraries, including the boost::asio library. When I try to compile the code in VS2010 I get the following errors:

1> Please define _WIN32_WINNT or _WIN32_WINDOWS appropriately. For example:
1> - add -D_WIN32_WINNT=0x0501 to the compiler command line; or
1> - add _WIN32_WINNT=0x0501 to your project's Preprocessor Definitions.
1> Assuming _WIN32_WINNT=0x0501 (i.e. Windows XP target).

Any help would be much appreciated.
