Automatically respond to runas from batch file

Question

I'm trying to get a batch file to automatically enter the password into the "runas" program, but I can't get it to work. Here's my batch file so far:

echo password | runas /user:testuser c:/path/to/my/program.exe

However, I get an error saying "unknown user name or bad password". I have also tried:

runas /user:testuser c:/path/to/my/program.exe < c:/path/to/file/containing/password.txt

This comes back with the same error. Does anyone know a way to do this? What I'm trying to do eventually is get the batch file to read a username and password from a config file, and then start "program.exe" as that user.

Solution

The Batch-JScript hybrid script below do what you want. Save it with .bat extension.

@if (@CodeSection == @Batch) @then
@echo off
start "" runas /user:testuser c:/path/to/my/program.exe
CScript //nologo //E:JScript "%~F0"
goto :EOF
@end
WScript.CreateObject("WScript.Shell").SendKeys("password{ENTER}");

Thanks! I had got something working by creating a .vbs script from the batch file, but this also works and is much more succint!
