Hi Luc,
  The program is compiling with a different compiler . But with Borland C++
5.5 it still refuses to compile . It gives the error "Unresolved external
'_main' referenced from c:\borland\bcc55\lib\cox32.obj". With a different
compiler it compiles perfectly . Can you tell me why it does not compile
with BC++ 5.5 . The code is as follows:

#include<winsock.h>
#include<windows.h>
#include<stdio.h>
#include<string.h>


#include <shellapi.h>
#include <stdlib.h>


struct WSAData WSAD;


int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR
lpszCmdLine,int nCmdShow)
   {



   SOCKET sockdesc,new_sd;
   int theirsize;
   struct sockaddr_in my_addr;
   struct sockaddr_in their_addr;
   WSAStartup( MAKEWORD( 1, 1 ),&WSAD);
   memset(&my_addr,0,sizeof(struct sockaddr_in));
   memset(&their_addr,0,sizeof(struct sockaddr_in));


   my_addr.sin_family=AF_INET;
   my_addr.sin_addr.s_addr=htonl(INADDR_ANY);
   my_addr.sin_port=htons(23);

   sockdesc=socket(AF_INET,SOCK_STREAM,0);
   if(sockdesc<0)
    {
   printf("err in socket %d \n",sockdesc);
           }


   if((bind(sockdesc,(struct sockaddr *) &my_addr,sizeof(struct
sockaddr_in)))<0)
   {
     printf("err in bind \n");
   }

   if((listen(sockdesc,2))<0)
   {
     printf("err in listen");
   }
   theirsize=sizeof(struct sockaddr_in);
   new_sd=accept(sockdesc,&their_addr,&theirsize);
   if(new_sd<0)
   {
     printf("err in accept %d \n",new_sd);
   }
   }
