How to send the keystroke 'q' to an application remotely with Powershell

Hi guys,

how can I execute the following script on a remote machine:

$wshell =New-Object-ComObject wscript.shell;
$wshell.AppActivate('title of the application window')Sleep1
$wshell.SendKeys('q')

I tried it with a function:$a ={functionClose_window{
$wshell =New-Object-ComObject wscript.shell;
$wshell.AppActivate(‘name of the window’)Sleep2
$wshell.SendKeys('q')}Close_window($args)}

$user ='user'
$pw ='password'
$password =ConvertTo-SecureString $pw -asplaintext -force
$credential =New-ObjectSystem.Management.Automation.PSCredential $user, $password

$servers =Get-content D:\test.txt
foreach ($server in $servers){
        $session =New-PSSession-ComputerName $server -Credential $credential

        invoke-command -session $session -ScriptBlock $a}

I also found this:

$scriptobjects =@() $scriptobjects +={ $wshell =New-Object-ComObject wscript.shell; $wshell.AppActivate(‘Untitled-Notepad’)Sleep2 $wshell.SendKeys('q')} $scriptobjects |foreach {& $_}

but I did not manage it to run on a remote machine, the result is always FALSE :-(

I would be happy if someone could help me with this!

Many thanks in advance

Paul
