Thanks Greg, this is the code I got some of this from a project I
founded in Internet, when I use the DrawToScale function or I try to set
the Image ( both are commented out ) I get the same error " invalid
argument " ????
I was not able to find any wrong argument in the code, but I'm new to C#
so please help me out :))
Thanks,
Paolo L.

Paolol, we really need to know what the error is to be able to help. How
about posting the complete text and the code that caused it.
