Can you double check this answer for me please?Nicholas Paldino said:Peter,
Short of actually replacing user32.dll with a shim that calls the originals, there isn't a way I can think of to do this.
Also, with the new windows protection scheme (windows knows when you try to replace system dlls and whatnot), I doubt you could
even do that.
And if you could, I certainly wouldn't want (nor could you do it easily) with .NET, and you definitely couldn't do it with C#.
Hope this helps.

I wouldn't have responded if I didn't think that it was correct. You could easily look for this information on your own, now
that I have given you some specifics, as well as potential concerns.
It probably would be helpful to know what you are trying to do, as well, so we could provide alternatives, since the solution I
gave isn't desirable, by any means.

Nicholas Paldino said:Peter,
It would be easier for you to actually enumerate through the users desktop directory to see what is displayed on the desktop.
If you are trying to do this, just find the users desktop directory, and enumerate through the items in the directory, and it
should give you a good idea of what is there.
As for the font information, for what is displayed on the desktop, that is the system font, and you can get that easily.
