File System Filter: Problem to deployed a filter on Wince 5.0

Hi everyone,

After a small pause, I'm back to the project explain earlier. ("Can I
have your advice on a problematic" posted on
microsoft.public.windowsce.platbuilder)

I've clarified the problem.
I must create a filter which will be register on
HKEY_LOCAL_MACHINE\System\StorageManager\Filters.

I've respected this procedure:
[HKEY_LOCAL_MACHINE\System\StorageManager\...\Filters\FilterName]
"dll"="filter.dll"
"Order"=dword:x
explain on the msdn site.

And I've put the dll on the folder "Windows".

My filter is the sample "encfilt" without any modifications.

On the emulator Pocket Pc 2003, it run perfectly. I created a file .txt
and its extension became .psw on my PC.

But on the emulator Pocket Pc 2005, my filter is ignore.

Is there anything I forget to do for the version 5.0???

Thanks for your help.

Hi,

Me again.
Always testing.

I've made the same procedure on a Qtek 9100 and after the soft reset, my
key created under HKEY_LOCAL_MACHINE\System\StorageManager\Filters\ have
disappeared from the regitry.

Why?????

Just a thought - is your code signed? services have to be code-signed for
WM5.0 and I suspect file system filters do too.

Hello,

I agree for the device but does Emulator need code-signed too?

And if it's the problem, how may I do to signed my code. (Which is not
from me but from Microsoft... all rights reserved ;) )

Is there someone who know what encfilt do?

I've deployed it on a pocket pc 4.2, but each txt files I create were
clear and readable. For an encrypt filter, it's astonishing.

Hi,

I progress. I've deployed the encfilt on my ppc, and I've discovered
that the function FILTER_CreateFileW was called when I create a file...
but only when it's on a storage card!!!

But I've registered it on:
HKEY_LOCAL_MACHINE\System\StorageManager\Filters

And I read on the msdn:
> If there is a file system filter in HKEY_LOCAL_MACHINE\System\StorageManager\Filters, then all file systems get the filter.

If someone can explain me, it will be really great

The link
http://blogs.msdn.com/ce_base/archive/2006/02/22/Encryption_and_Filters_between_WM2003_and_WM5.aspx
says something about where encryption filters can be used. As I
understand it an ISV (Independent Software Vendor) cannot create a
filter for something in RAM. Anyhow the article explains it a lot
better than me.

Good Luck

Thanks for your help,

Indeed, it has helped me.

Visibly, I must develop my own File System DRIVER (and not only filter),
but it seem to be a little more difficult. Do you know some link where I
can find sample which guide me.
