You should look at euphoria\demo\win32\window.exw
in the Euphoria 2.2 release. It contains the code
that you need to display an icon in the top left corner
of a window. The 3 key lines are:

icon_handle = c_func(LoadIcon, {instance(), allocate_string("exw")})
poke4(wndclass + hIcon, icon_handle)
poke4(wndclass + hIconSm, icon_handle)

The standard icon contained in exw.exe for 2.2 is
called "exw" regardless of what you call your bound .exe file.
When you run bindw, you can specify an icon of your own,
but the name will still be "exw".

Your icon must contain a single image, and be 2238 bytes
or less in size, otherwise it might not be displayed. (see bind.doc)
