please see this code:

The VB problem can be ignored. It’s just telling you that a method you’re using has been replaced by a better one which you should consider switching to. You don’t have to though, for the time being that obsolete method is still there.

thanks…do you have any suggestion gh or code to this function(extract icon from grasshopper 32x32 bitmap)?
