Hi Art,

You are not going to have much luck with that, I don't think.  The Windows
shell is always going to want an executable or DLL with the icon bound into
it, and the index of that icon, I believe.

Your best bet would be to compile a resource only DLL and bind the icon to
that.  Then use that DLL as the icon file name with the index you use for
the icon resource.

Compiling a resource only DLL is really pretty simple.  If you have a
working NSIS install script, you can easily compile a resource only DLL.
 It just involves downloading and installing a Windows SDK.  The SDK is
free.

Oliver Sims who is writing the ooDialog User Guide, has mastered that.  I'm
sure he would answer any questions concerning the details.

You could look at the winsystm.cls, where the WindowsProgramManager class
has the addDesktopIcon method. It might help, but I think not.  I think the
Windows Shell requires the icon to be in a compiled resource.  It is not
going to load an icon from an icon file.
