How to execute command line statement (dir) and return the value

I have a dir statement that I would like to run via Jscript.  I would like to call the cmd.exe process and then execute this statement: dir /a /s c:\ |find /c /v "".



Here is my sample code, but I can't figure out how to get it to work:



  var WScriptObj = Sys.OleObject("WScript.Shell");

  // Ping the server

  var ExecOperation = WScriptObj.Exec("cmd /c dir /a /s c:\ |find /c /v \"\"");



  // Check the operation's status

  while (ExecOperation.Status == 0)

    Delay(100);



  // Obtain the operation's exit code

  var ExCode = ExecOperation.ExitCode;



  // Obtain the application's StdOut stream

  var StdOut = ExecOperation.StdOut;



  if (ExCode == 0)

    Log.Message("Connection succeeded", StdOut.ReadAll())

  else

    Log.Error("Server is unavailable", StdOut.ReadAll())
