i am new to Visual C++ ..... know C++ so started with Sockets .

 

EDITi tried linking winsock.h but it shows

cannot open file 'winsock.h'

 

EDIT 2 : Solved that one too :? but now it shows some unwanted result ??

you need the proper libs. either use #pragma comment(lib,"whatever winsock lib is called") or manually specify via project settings.

i did that that solved most part of it, but 1 more problem
