Re: [Boost-users] boost::asio Visual Studio 9 - fatal error C1189: #error : WinSock.h has already been included

Julian,

you might want to

#define _WINSOCKAPI_   /* Prevent inclusion of winsock.h in windows.h */

before including any headers in your file. This way only winsock2.h will  
be included. Or, alternatively, you can try to include winsock2.h yourself  
before anything.

Have fun
   Andrey.
