Capturing output from WshShell.Exec using Windows Script Host

Question

I wrote the following two functions, and call the second (\"callAndWait\") from JavaScript running inside Windows Script Host. My overall intent is to call one command line

You might have hit the deadlock issue described on this Microsoft Support site.

One suggestion is to always read both from stdout and stderr. You could change readAllFromAny to:

function readAllFromAny(oExec)
{
  var output = "";

  if (!oExec.StdOut.AtEndOfStream)
    output = output + oExec.StdOut.ReadLine();

  if (!oExec.StdErr.AtEndOfStream)
    output = output + "STDERR: " + oExec.StdErr.ReadLine();

  return output ? output : -1;
}
