I’m having difficult time making disk drives that my driver creates
appearing in Win Explorer on XP platform.
On NT and W2K I was broadcasting volume arrival and Explorer was
successfully refreshing, so my
disk drives were showing up. But not anymore on XP. Even worst! Manual
refresh of the Explorer doesn’t
help at all. Disks are still “hidden”. The only way I can make them appear
is to kill explorer process using
taskman and then start it again.
On one of the plugfests I’ve been told that this is “we know about it” kind
of bug. Well, this doesn’t cheer me up
anymore 
Can anybody provide me with a suggestion how can I make my disks appear
(preferably both, programmatically
and administratively) in Explorer without killing its process?
Thanks in advance,
Vladimir

Vladimir,
I was thinking about this today. My first question was - “how are you
creating the drive letters.” I think that if you aren’t using the mount
manager, then my first suggestion would be to see if using the mount manager
fixes the problem. If not, I’m not sure why Explorer has changed its
mechanism - but it must have done so.

Tony

Tony,
you’re right, explorer changed its mechanism; several times during XP beta
phase. It was broken in beta 2 and fixed later. Changes affect drive letters
created ‘old’ way without mount manager help. Our virtual disk driver was
affected the same way how Vladimir describes but now works with no problem
with broadcasting. I can’t check it now, in some phase it was necessary to
add DBTF_NET flag for broadcasts but it might be for buggy beta 2. To find
what really causes Vladimir’s problem it may be necessary to debug
shell32.dll routines which handle broadcast.

P.S. Vladimir, I haven’t responded to your message previously because

> Michal:
So, as I understood, you were able to solve this problem by just adding
some messages/flags to “broadcast system message” (don’t remember exact
API name)?
Yes, mentioned flag for BroadcastSystemMessage is in our final version so it
is probably necessary. A kind of hack but what to do when somebody smart was
tempted to ‘fix’ what worked for years?

Vladimir
P.S. Hmmm… I had no idea that my messages are sent in HTLM!
I receive them as attachments and replying to attachments is awkward.
