How to read the windows registry?

I can successfully open the 'WScript.Shell' COM object but cannot seem to
access the 'HKEY_CURRENT_CONFIG' root system. I am trying to read the
current screen resolution in width and height.

The error I get is 'Invoke() failed, Exception occurred'
Warning: (null)(): Invoke() failed: Exception occurred.
Source: WshShell.RegRead Description: Unable to open registry key
"HKEY_CURRENT_CONFIG\System\CurrentControlSet\Cont rol\VIDEO\" for reading.
in C:\php434\registry.php on line 8

code:
<?php

$reg = new COM("WScript.Shell") or die("Requires Windows Scripting Host");
$k =
"HKEY_CURRENT_CONFIG\\System\\CurrentControlSet\\C ontrol\\VIDEO\\8B6D7859-A6
39-4A15-8790-7161976D057A\\0000\\DefaultSettings.XResolution\\" ;

echo $k."\n\r";
$disp = $reg->RegRead($k);
echo '-'.$disp."-\n\r";

?>

If the key does exist, I'd check whether the user the script is running as
has permission to read the key.

I suppose you're writing a shell script or something similar, aren't you?

Yes, I am writing shell scripts. I have started to think that maybe
permissions is the problem as I can read some keys and not others.

Thanks for the info.

Run regedit and check permissions right-clicking on the key.

Got it... I did mess with the permissions a bit but I think the main
problem was not including {} around on of the key names... Thanks!
