[C++]ws2_32.dll compilation help

im trying to compile a .DLL for hacking an online game. currently making something like a pocket sender..

anyways, someone told me to use this code..
i've tried to edit it a little.

and tried to compile it.. but got errors..

i hope you can help me fix it.. thanks..

#include <fstream>
#include <stdio.h>

Wide vs. ANSI. Change your project's settings or use the TEXT macro like so:

Code:

osend         = (r_send) GetProcAddress(GetModuleHandle("ws2_32.dll"), "send");
orecv         = (r_recv) GetProcAddress(GetModuleHandle("ws2_32.dll"), "recv");

Code:

osend         = (r_send) GetProcAddress(GetModuleHandle(TEXT("ws2_32.dll")), "send");
orecv         = (r_recv) GetProcAddress(GetModuleHandle(TEXT("ws2_32.dll")), "recv");

Variable "i" is only declared inside of the loop.

Code:

for (int i=0;i<size;i++)

Code:

int i;
for (i=0;i<size;i++)
