Hi people
I do believe dokan is fantastic. I've tested some stuff using the .NET
wrapper without any trouble, but since i'm doing research within the C+
+ space, i cannot make my dokan code to work properly.
Below is part of my code, the rest of it is exactly the same as the
mirror.c (example) that came with the package. I'm using a VC++
project, character-set Unicode. The thing is that i cannot get the
mount appear on my system, unless i change the value of RootDirectory
(GetFilePath function) to something like L"\\\\.\\%L:" (or any other
garbage).
I just wanna have a virtual drive where i can create/copy and use it
like a normal drive, to store different files.
Please, let me know what am i doing wrong.

Hi ,
Just to be clear, I take it L is not the letter of the virtual drive but is the letter of the drive you are redirecting to?
It looks like L is the virtual drive and the one your are redirecting to. If so, that's your problem, it's a loop.

You need to use an existing path as RootDirectory.
There are also some mistakes in your code.

Yes, i did realize that i couldn't get "disk space" magically, that i
would need to attach the virtual drive to an existing path. I'm now
enjoying and playing; i'm involved in a personal project that i will
share with you guys as soon as it's ready. If you like it, you can
join the development team: i plan to deploy both Linux/Mac versions.
Anyway, i'll tell you when i have something.
All my best, and thanks for your tips.

Well, i'm almost there to the final stage of my development process.
But, i still have a few questions/issues awaiting to be attended:
1 - Why i cannot see a normal context menu? When i browse my new
drive, i right-click in the explorer window and the "New" submenu in
the context menu just shows the "Create folder" option.
2 - I cannot rename a file, it says "it already exists" when i choose
a new name (obviously, it doesn't). The same happens when i move a
file into another directory (same dokan drive).
Please, i think if i have this issues solved, i will be in place of
telling you that i know how to use dokan. I repeat: it's a great
solution.
THanks all and regards,
Nicolas

This is very strange:
When i try to rename a file or a folder, i cannot write more than one
character.

Hi Joe
I haven't had a chance to give you my thanks for your attention, is
nice to see someone takes care of Dokan :-)
Well... i think i found some kind of bug, and i cannot guess why it
happens.
Please, first take a look at this video and you'll understand my
point:
http://screencast.com/t/ZjU3YzIz
Translate "Nuevo" with "New" (it is the common windows explorer
context menu, where you can choose to create new folder, documents,
shortcuts, etc).
The context menu is not properly displayed. When i go to a sub-folder,
i can see it right. But, on the root folder i need to make some tricks
with....... MOUSE CLICKS! yes... the last second, you'll see the
context menu because i clicked both mouse buttons.
Weird... trying to guess what is it.
My kindest regards,
Nicolas Iglesias

Hi Nicolas,
Off the top of my head can't think of anything that would cause this, unless the file system isn't returning consistent results.
No custom Explorer namespace I take it.
The dokan mirror example isn't doing it for me, neither is my dokan filesystems, so I don't think it's a Dokan bug.
In you logging, print out the paths too.
Might give more insight into what is going on.
Sorry I can't help more.
