Re:About file system filter on windows mobile - Pocket PC Forums - Pocket PC Live!

Hi All,

I was posted topic about developing file system filter on windows mobile.
Now, I am successful to do this.
I have successfully loaded my filter on windows mobile.
But it is just for a SD Card only.
Now I want to know, Is there any way to write the filter for the whole file system for windows mobile?
i.e for "ROOT" directory of windows mobile.

If any one have idea about it then please reply.

Thanks & Regards,
Pariksheet.

That's great news. But how did you manage to do it for the SD?

I presume you used MFC?

Hi Carty,

Yes, I am using MFC.
I have used the FSDSPY sample.
And I made the registry entry as:
[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\SDMMC\Filters\fsdspy]
"Dll"="fsdspy.dll"
"Order"=dword:1

And when I configure the local PC folder as SD Card Then my filter is loaded in filesys.exe.
To configure SD Card, goto "File" menu on emulator window. the goto "configure" option.
In configuration dialog, in "general" tab there is "shared folder" option. By browsing any local folder on your machine you can get that folder as SD Card on emulator.
I checked it on WM6.
On WM5, it loads the filter but my dll did not catch any action I have taken.
What will be the problem with WM6?
And can we make file system filter for RAM/ROM file system on Windows Mobile.

Awaiting for your reply.

I believe the File System filter on Main Memory can only be achieved before boot process and only OEM's can do it. While building a ROM, I came across this under boot.hv and so probably to make a filter on Main Memory, your dll needs to be registered before the device boots or during the boot process.

Anyway, what is the reason that you want a filter to main memory? Creating a Kiosk?

Yes, I also found that I have to load it on boot time.
But I don't know how to do that.
So, is there any way off to do this.
to register dll on boot time?
How can we achieve it?

That is not possible through programming as far as I know. You can only do it by modifying the ROM. That is why it's restricted to OEMs.
