Getting a handle to an icon

[Peter Foot [MVP]]

It is not possible to get a native hIcon from a managed System.Drawing.Icon
object.

The workaround we use in our NotifyIcon class is to use ExtractIconEx to get
a hIcon of the current application executables default icon:-
hIcon =
ExtractIconEx(System.Reflection.Assembly.GetCallingAssembly().GetName().CodeBase,
0, 0, ref hIcon, 1);

[DllImport("coredll", EntryPoint="ExtractIconEx", SetLastError=true)]
private extern static IntPtr ExtractIconEx(string lpszFile, int hIconIndex,
int hiconLarge, ref IntPtr hIcon, uint nIcons);

It is possible to use native icon resources from any exe or dll in this way.
Be aware however that icons added as resources to your .NETCF executable are
not stored as native icons - you will need to use a native resource editor
to package them. Windows CE does not include a method to load icons from an
ico file.

You may also find Alex's article on Icons useful, it concentrates on
building a managed icon from a hIcon but discusses the structure of an icon.
