Socket handles

hi everybody,I am a beginner in C programming and i am currently learning sockets. I am now able to make my socket listening.My next challenge is to make a server that spawn a program like cmd or a command line program when a telnet client connect to it. I must admit that i need help for this one. I found that the easier way is to make a listening socket, handle the process then create the process. Iwrote a code but i can t make it work.Maybe someone can tell me what s wrong with my code or give me some advices.Here is my code (wich might be full or errors :p ):

Code:

---

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

int main() {


  WORD sockVersion;
  WSADATA wsaData;

  sockVersion = MAKEWORD(1, 1);

  WSAStartup(sockVersion, &wsaData);

  SOCKET mysocket;
  mysocket = socket( AF_INET,
                      SOCK_STREAM,
                      IPPROTO_TCP);

  SOCKADDR_IN serverInfo;
  serverInfo.sin_family = AF_INET;
  serverInfo.sin_addr.s_addr = INADDR_ANY;
  serverInfo.sin_port = htons(12235);
 
  bind(mysocket,(LPSOCKADDR)&serverInfo, sizeof(struct sockaddr));

  listen(mysocket, 10);

  SOCKET client;
  client = accept(mysocket,
                          NULL,
                          NULL);

  HANDLE currentProcess;
  currentProcess=GetCurrentProcess();
  HANDLE output;
  DuplicateHandle(currentProcess, (HANDLE)client, currentProcess,
  &output, 0, TRUE, DUPLICATE_SAME_ACCESS);

  HANDLE input;
  DuplicateHandle(currentProcess, (HANDLE)client, currentProcess,
  &input, 0, TRUE, DUPLICATE_SAME_ACCESS);

 

  STARTUPINFO          si = { sizeof(si) };
  PROCESS_INFORMATION  pi;
  char                szExe[] = "cmd.exe";
  si.dwFlags=STARTF_USESTDHANDLES;
  si.hStdInput=input;
  si.hStdOutput=output;

  if(CreateProcess(0, szExe, 0, 0, TRUE , CREATE_NEW_CONSOLE , 0, 0, &si, &pi))
  {
    CloseHandle(pi.hProcess);
    CloseHandle(pi.hThread);
  }
   
  CloseHandle(input);
  CloseHandle(output);


  closesocket(client);
  closesocket(mysocket);

WSACleanup();
return 0;}

Could you be more specific? What errors are you getting? Where are you stuck? What's happening that shouldn't be, or vice-versa?

in fact, it compile without any problem, the server is listening on the specified port but when i connect with the windows telnet client i don t get the expected cmd.exe.
I think the problem come from the process handle
