StdIn Property (WshScriptExec)

 

Exposes the stdin input stream of the Exec object.

Object.StdIn

Object

WshScriptExec object.

Use the StdIn property to pass data to a process started using Exec.

Legacy Code Example

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);
