Hi,
I need to retrieve icons of files in my .net application. Because the
method fromHandle() doesn't exist in CF, i'm using this great code that
transforms a win32 icon HICON to a managed icon:

I find this rather slow method when it is necessary to treat a big
number of files. Is not there a faster method in .NET? Thank you

The reason it's slow is that it requires building an icon on the fly from
your hicon data. An alternative would be to look at how you output the icons
from which you have a hicon. For example you could use P/Invoke to call
DrawIcon to draw the icon on a form. The story does get better in .NETCF
v2.0 as the Icon class includes the FromHandle method.
