/*
|
|
* This program kbswitch is a mimic of Win2k's internat.exe.
|
|
* However, there are some differences.
|
|
*
|
|
* Comparing with WinNT4 ActivateKeyboardLayout, WinXP ActivateKeyboardLayout has
|
|
* process boundary, so we cannot activate the IME keyboard layout from the outer process.
|
|
* It needs special care.
|
|
*
|
|
* We use global hook by our kbsdll.dll, to watch the shell and the windows.
|
|
*
|
|
* It might not work correctly on Vista+ because keyboard layout change notification
|
|
* won't be generated in Vista+.
