Hey Justin,

Thanks for your reply!

I tried that, which didn't work sadly, but gave me a bit more information.

Now I get "Cast from 'JScriptTypeInfo' to 'String' is invalid...."

So the object type that I'm getting is really one of these strange
"JScriptTypeInfo" ones, on which I can't find any useful information!

Anyone got an idea how I can cast that object to a String? :)

I know it must be possible as Microsoft have an application which calls
into JavaScript functions and uses the return value.

Thanks again,
