Updating icon resources of application

Hello.

I want to develop an application that let me update a resource of another
one.
I developed a method to update strings of the string tables resources and to
update bitmaps resources.
My problem appears with icon resources and I don't understand very well how
icons go.
I read an article "Icons in Win32" in MSDN, but I don't understand how
transform RT_ICON (that we have in .ico file) to RT_GROUP_ICON (that we have
in exe resources).
I tried to read .ico loading information in structures (ICODIR,
ICONDIRENTRY) and creating structures for RT_GROUP_ICON (GRPICONDIRENTRY,
GRPICONDIR).
Finally I don't understand how can copy ICONIMAGE and how I can associate to
group_icon the image readed from the .ico

Could anybody explain something about it? Could anybody explain how I can
write the code?

Thanks at all

Jordi
