FBWF and non persistent registry settings across reboot.

[Guest]

Hi,
I'm experiencing the new features of FP2007 and specifically the File-Based
write filter. At runtime, I've to align a resistive touchscreen (because each
device is different aligned from each other) with an executable wich saves
his settings under the HKLM\System\CurrentControlSet\Enum etc.. So, after
aligning, I perfom the command 'fbwfmgr c: \WINNT\System32\Config\System' and
the fbwf tell to me that the system registry hive is committed to the compact
flash without error. But after reboot that registry settings are lost! If I
specify the '\WINNT\System32\Config\system' hive file like write-trought file
in the target designer, all is ok and the settings in that hive are persisted
across reboot. Please note that if I try to modify another WriteFilter
protected file (like eula.txt with the Notepad) and after I perform the
commit command to the filter, that modified file persist on the next reboot,
so the behaviour of the filter appears ok. Any suggestion or idea? Thanks.

Have you ever thought about using Registry Filter Component? It also
is new in FP2007. You can setup your own registry keys for monitoring.
They will survive a reboot. It is a nice feature, specially for
calibrating touchscreens.

Andrea,
Can you try changing another key under HKLM\System\CurrentControlSet\
Then commit the same way.

Will that key persist accross reboots or is it only a problem with Enum key?

thanks

Dear Milong (and Stefanie),

every key I try to change in HKLM\System\CurrentControlSet\... will not
persist after reboot. Maybe the System hive is locked by the XPE so it deny
changes maked by the FBWF? This behaviour explains why if I set the write
through to System hive at designer time or at runtime using the fbwf console
manager, all is ok....
I never consider using the registry filter component but i'll try to use it
the next days.
Thanks.

Hi Andrea,
Can you tell me what is in your configuration? What templates and other
components you are using?
