StdOut Property (WshScriptExec)

Exposes the write-only stdout output stream of the Exec object.

                      Object.StdOut

• Object
  WshScriptExec object.

The StdOut property contains a read-only copy of any information the script may have sent to the standard output.

The following code starts a batch file and waits for the user input prompt. After entering the needed data through the StdIn stream, the batch file will be able to complete.

Dim WshShell, oExec, input
Set WshShell = CreateObject("WScript.Shell")
Set oExec    = WshShell.Exec("test.bat")
input = ""

Do While True

     If Not oExec.StdOut.AtEndOfStream Then
          input = input & oExec.StdOut.Read(1)
          If InStr(input, "Press any key") <> 0 Then Exit Do
     End If
     WScript.Sleep 100
Loop

oExec.StdIn.Write VbCrLf

Do While oExec.Status <> 1
     WScript.Sleep 100
Loop

var WshShell = new ActiveXObject("WScript.Shell");
var oExec    = WshShell.Exec("test.bat");
var input = "";

while (true)
{
     if (!oExec.StdOut.AtEndOfStream)
     {
          input += oExec.StdOut.Read(1);
          if (input.indexOf("Press any key") != -1)
               break;
     }
     WScript.Sleep(100);
}

oExec.StdIn.Write("\n");

while (oExec.Status != 1)
     WScript.Sleep(100);
