i am using visual studio 2010 version. I am getting error while building a solution.
I think this error is related to platform version. But i don't know how to change this version to different version. here is following is error.
c:\program files\microsoft visual studio 10.0\vc\atlmfc\include\atlcore.h(35): fatal error C1189: #error : This file requires _WIN32_WINNT to be #defined at least to 0x0403. Value 0x0501 or higher is recommended.

so how to solve this problem.
