may be because the INCL_WINSOCK_API_PROTOTYPES got define before including the winsock2.h . I dont know how it got define.

Try including "winsock2.h" above all other includes.( if ur using stdafx.h, put

#include winsock2.h above the first include in it)

try this. I am not sure whether this a right way to do. How ever if the error was because of the pblm I above mentioned, it will compile fine when wrote as below

#undef  INCL_WINSOCK_API_PROTOTYPES<br />
#include <WinSock2.h>

It because of your logic. You are using boolean operation as case input. Which is repetitive. case should be different in switch statement.

case('m'||'M'):

This is wrong. This will in fact evaluate to a boolean, not a character. What you need to do is this:

case('m'):<br />
case('M'): <br />
// Code here<br />
break;<br />

What is the cause for this error?

you only have to use constant in case field.. switch case just work like goto statement but with scope

Use
choice = (char)toupper( choice ) ;
switch( choice )
{
case 'M' :
----------
----------
break ;
case 'C' :

break ;
}

You should call this function like,

HINSTANCE hinstLib = LoadLibrary(_T("Mydll.dll"));

You need to ask question in message board of that article only. Use rebuild command to build the application.
