Re: Get Host ID

This function is kind of MFC-centric, but it may work for you:

#include <winsock.h>
#include <winnetwk.h>

//
// Returns the host name and IP address
//
CString GetHostName(CString &csIPAddress)
{
     CString compName;
     _TCHAR buff[MAX_COMPUTERNAME_LENGTH + 1];
     DWORD count = MAX_COMPUTERNAME_LENGTH + 1;
     compName.Empty();
     if (::GetComputerName(buff, &count)) {
          compName = buff;
          WORD wVersionRequested;
          WSADATA wsaData;
          char name[255];
          PHOSTENT hostinfo;
          wVersionRequested = MAKEWORD( 1, 0 );

          if(WSAStartup(wVersionRequested, &wsaData) == 0) {
               if(gethostname(name, sizeof(name)) == 0) {
                    if((hostinfo = gethostbyname(name)) != NULL)
                         csIPAddress = inet_ntoa (*(struct in_addr
*)*hostinfo->h_addr_list);
               }
               WSACleanup( );
          }
     }
     return compName;
}
