You're asking queryRegistry() to give you the names of all the items in the 
'\Enum' folder (not the correct term, but the metaphor fits). However, 
queryRegistry() isn't smart enough to do that. It only knows how to return the 
value of a specific registry item.

So here's what you can do: Open RegEdit on your Windows machine and *very 
carefully* navigate to the above node/folder/endpoint. See what items are in 
there, write them down and close RegEdit. Then ask queryRegistry() for one of 
those values. It'll do it!

For example, if you put "0" (zero) after "Enum\" in the above reg path, you'll 
see the value stored in the item named "0". (Assuming there is an item by that 
name - should be)

Caveats:
Some registry values are stored as double-word binary data, so (typically) you 
have to convert them to chars before they are of much use.

Have fun!
Phil
