Hello,

I would like to control a command=line app from my program. I tried to 
do this by opening a pipe and specifying that pipe as the standard input 
handle in CreateProcess = but it does not work. I send my code, too. I 
run it on WinXP SP1. How can I make it work? Thanks.

   HANDLE hPipe, hClient;
   hPipe = CreateNamedPipe( "\\\\.\\Pipe\\MyPipe", PIPE_ACCESS_DUPLEX,
                            PIPE_TYPE_MESSAGE | PIPE_WAIT,
                            PIPE_UNLIMITED_INSTANCES,
                            1024, 1024, NMPWAIT_USE_DEFAULT_WAIT, NULL);
   hClient=CreateFile( "\\\\.\\Pipe\\MyPipe", GENERIC_READ | 
GENERIC_WRITE, 0,
                        NULL, OPEN_EXISTING, 0, 0);
   sti.hStdInput = hClient;
   sti.hStdOutput = GetStdHandle( STD_OUTPUT_HANDLE);
   sti.hStdError = GetStdHandle( STD_ERROR_HANDLE);

   CreateProcess( 0, "cmd.exe", 0, 0, TRUE,
                  NORMAL_PRIORITY_CLASS,
                  0, 0, &sti, &ps);
   char *s = "bla.bat\n";
   DWORD d, x;
   char buffer[256];
   x=WriteFile( hPipe, s, strlen(s), &d, 0);
   FormatMessage( FORMAT_MESSAGE_FROM_SYSTEM, 0, x=GetLastError( ), 0, 
buffer, sizeof(buffer), 0);

   CloseHandle( hClient);
   CloseHandle( hPipe);
