Is there a nice way in the .NET framework to load an icon resource that is
embedded within a Win32 DLL? I noticed that the SystemIcons class comes
close (it is probably invoking the same Win32 call I need to invoke), but
doesn't allow me to specify an icon name.

I have also looked at the Icon class, but it doesn't seem to have anything
to do what I want either. I would like to avoid having to use interop to
get the HICON and the create an Icon class.

Thanks, Tyler

There is nothing in the framework, but you will find a nice sample there:

Not really, I think you have to call the ExtractIconEx Win32 API.

Do you know whether ownership of the HICON is taken over by the Bitmap class
when I do a Bitmap.FromHIcon or must I call DestroyIcon after creating a
bitmap from the Icon? Is there anyway to tell that from the .NET
documentation?

Thanks again for your assistance, Tyler

HiTtyler,
Thanks for using MSDN Newsgroup!
Bitmap class just uses the Icon handle, it will not take the ownership
of that handle, so you need
destroy it by yourself.
If you have any further questions on this issue, pleaset le me know.
Thanks!
