Winsock2.h and Platform SDK
 

I am trying to develop a basic communicating link using windows sockets in visual studio.net2003... but it is showing an lnk2001 error.. is it necessary that have to get the platform SDK and install it before i can use winsock2.h????

Re: Winsock2.h and Platform SDK
 

You probably just need to incude the appropriate .lib in your studio project. Without the link error, I don't know which .lib...)
