Changing a filetypes icon - adding a"shortcut" like mini-icon

Mayayana,

And MS reserves 4 of them.

I've not seen that mentioned anywhere. Maybe the number of "free slots" is
given /after/ MS has already taken its share ?

And apparently many are used up by the likes of Dropbox.

Lucky me, as I do not use that. :-)

So maybe using informative file names instead isn't such a
bad idea.

True. Its just that in my case I let the program loading the "overlay"
dynamically generate the name of the "overlay" - in the simpelest way:
GetModuleFilename followed by a PathRenameExtension (the program and its
"overlay" can be moved and even renamed)

Besides that, the "overlay" has the same icon as the program thats starting
it - which (at least in my case) can easily lead into clicking the wrong
entry (not that anything bad happens, but still)

Than again, maybe I should really just pick a different, static icon for the
new .ovl filetype ...

P.s.
I just did put a COM-object together which (currently) applies that icon #30
to a fileobject with a specific extension. Turns out it only needs a
single object (IShellIconOverlayIdentifier,
{0C6C4200-C589-11D0-999A-00C04FD655E1} ) to make it work.

Drawback is that it looks like that only a single overlay icon can be
applied at a time*, so its not possible to have four, each in another
corner**. Though maybe thats good too, as that would get rather messy
fast.

*A priority must be provided wit the overlay icon, and the one with a
highest priority will be used.

** I can stil create an overlay icon that /looks/ like its in another
corner, but only one will be present at any time.

Ed,

You've misinterpreted my advice.

Ah yes : when you don't understand my explanation its my problem and I need
to "delineate" "more explicitly", but when you make a mess of it its my
misinterpretation thats to blame. Sure.

Now then, you have ended up in a cul-de-sac trying to solve a problem; and
your brain clamours "I need to manipulate Window's shortcut facilities to
advance".

Have/do I ? And you know that ... how exactly ? And do you think you
can conclude that cul-de-sac with the subject being just over 24 hours old
when you did ?

Also, do you remember posting the below ?

"I strongly suspect that the little arrow isn't a system variable. If it
were we'd find it tweakable in Ultimate Tweaker or Winaero Tweaker."

In two sentences you show that you know little to nothing about the subject,
and more likely than not have simply overlooked the setting in both(!) those
tweaker programs. 'Cause as posted by Mayayana its actually rather easy to
do. And to add insult to injury, rather easy to google too.

This NG contains some very intelligent and Windows-savvy people who would
be capable of feasibility studies, fact-finding and recommendation
reports; the tools of a systems analyst. Use us.

Yeah, there are. I already spoke with a few. Its just that I don't think
you are one of them.

You "know" too much without bothering to support or (obviously) verify it.
And your "lets drop something before it has run its course and look at
something else instead" also doesn't quite work.

Have you gained a satisfying solution to the problem you put before us?
You've certainly stimulated some discussion, and maybe that's worth
something; but you still have your problem. And throwing **** around
like a low-life won't resolve that, so I won't go there.

Personal experience and its limitations; that's your way out of the
dead-end.
Have you ever faced a perilous challenge? One that takes you to the
limit? One where you're so taxed that your whole life flashes before
you, as your brain furiously searches its memories for a solution?
Yes? Well, what you saw on that panorama 3D screen in your head was your
own experience; not Einstein's, not Isaac Newton's, not Archimedes'. Nor
was it a manual of "A million and one solutions when on the brink". It
was your past life's pickings.
You might have benefited from a good wifi connection to the Internet, or
even to the experience of Hannibal Barca, the Carthaginian general who
led a mostly mercenary army across southern France, over the Alps in
mid-winter and down into Italy, where he defeated and slaughtered
several full consular armies of Rome.
But no, it was your own.

Thanks. I've stored it for possible future use.

JJ,

Also do notice that there seem to be only 15 "slots" available (presumably
ignoring the 16th-and-above IconOvelayHandler).

The limit only applies to the number of effective shell extensions in the
registry. But each can be proxied, chained, or hooked; to multiple shell
extensions. Making the limit ineffective.

I currently cannot quite imagine how that happens ... But if I'm lucky its
only a google away.

(I just tried to find some different overlay icons. It turns out that there
are rather few, and hard to find)
