};

so i can call it in the main.cpp as

PoPSocket soc;
soc.Socket();

but when am trying to finish the socket its keeping say

Error

Error	1	error C2373: 'htons' : redefinition; different type modifiers	
	2	IntelliSense: linkage specification is incompatible with previous "htons" (declared at line 1760 of "C:\Program Files\Microsoft SDKs\Windows\v7.0A\include\WinSock2.h")

can anyone please help me?!

This is not valid syntax:

u_short htons(u_short hostshort);

I think you want simply:

u_short htons(hostshort);

This is not valid syntax:

u_short htons(u_short hostshort);

I think you want simply:

u_short htons(hostshort);

now it's giving me new errors

Error 1 error C2065: 'hostshort' : undeclared identifier
2 IntelliSense: identifier "hostshort" is undefined

You should listen to the compiler :) 'hostshort' is indeed not declared anywhere in the code you've shown us.

check:http://www.madwizard.org/programming/tutorials/netcpp/4

he using

// Convert a u_short from host to TCP/IP network byte order.
u_short htons(u_short hostshort);

// Convert a u_long from host to TCP/IP network byte order.
u_long htonl(u_long hostlong);

// Convert a u_long from TCP/IP network order to host byte order.
u_short ntohs(u_short netshort);

// Convert a u_long from TCP/IP network order to host byte order.
u_long ntohl(u_long netlong);

and its working !!! idk whats wrong
