Module Name :

|
lpk_nls.c
|

|

|
Abstract:
|
||
|
|
|
||
|
|
This module picks up any changes to the NLS data which happen to the
|
||
|
|
registry. A thread is dispatched from the LPK and waits for an event
|
||
|
|
of a registry-change notification. This is a HELL-OF overhead, since it
|
||
|
|
envolves a thread overhead/process as long as the LPK is attached
|
||
|
|
to each process.
|
||
|
|
|
||
|
|
Current NLS information being set :
|
||
|
|
- Numeric Style (Native + Substitution). Currently for Beta-1 timeframe,
|
||
|
|
we'll just set the registry entry at setup time, and if user wants to change it,
|
||
|
|
he should go CURRENT_USER\Control Panel\International and change the value of
|
||
|
|
sNativeDigits and iDigitSubstitution.
