I'm a hobbyist and new to the D language.  With a lot of help 
from various online resources, I finally figured out how to load 
an icon from:

   1. A file "icon.ico" (this was easy)
   2. A Program extension from the Windows registry, e.g. "*.inf" 
(harder)
   3. A linked resource from the exe itsself (very hard)

I learned how to add an icon to the exe with a compiled Resource 
file.
Now I can load this embedded icon as the shell icon.
And I don't have to distribute a separate ico file with  my exe.
I added a couple of simple bat files to compile with either dmd 
or dub.

I hope this helps another newbie like me.
Constructive feedback is welcome.

In D it's very simple to embed resources in the executable at compile 
time using string imports:

immutable data = cast(immutable(uyte[]) import("foo.ico");

Compile by adding the -J flag to point to the directory where the icon 
files are located:

dmd main.d -J./resources

Then I'm pretty sure there's a an API that takes a byte array and 
returns an image of some sort.

Update: I expanded and renamed this project, now at:
https://github.com/jasc2v8/dwt-support/tree/master/windows/loadicon

The key takeway is the Win32 API LoadImage function.

Use to set the Shell icon from the program icon linked with 
icons.res in this exe file.
