Help! Getting the "default icon" for an application, but not what you think...

[Drebin]

OK, I need to pull out the default icon for application type. Picture in
Windows explorer, how the correct icon shows up for each file in a folder.

Turns out, you go into HKCR:[file extension] and pull out the default entry,
then you go under HKCR:[file type]\DefaultIcon - and that will be something
like %systemroot%\shell32.dll,14 - the location and icon number. Great!

Here's the tricky part. This works for every single file extension (and
..exe's are handled differently) **EXCEPT** for .txt and .log extensions.
These are associated with Notepad, and show the correct icon in Windows
explorer.. but in my application, it shows a funky/wrong icon.

In the registry, it's %SystemRoot%\system32\shell32.dll,-152

What's up with that? It's the only negative resource number I've seen.
Regular icon 152 is a CDROM, so that's not it.. so I don't even know how
it's finding ANY icon.

Any ideas of what's up with this? Do I understand correctly that the number
after the DLL is the internal resource id? if so, why is this a negative
number??? I'm stumped. Thanks in advance

you can extract an imageliste of all system icons, so you actually get
access to the exact same icons as the explorer. All without having to parse
the registry.
