Abstract:
|
||
|
|
|
||
|
|
The app has an executable bplayer.exe to launch its virtual CD driver. The
|
||
|
|
problem is bplayer.exe is put in start-group and will be launched by
|
||
|
|
explorer.exe, at the time the virtual CD driver is launched, explorer.exe
|
||
|
|
has already finished initialization and cached all local drive info. Fixing
|
||
|
|
this by broadcasting a WM_DEVICECHANGE message.
|
||
|
|
|
||
|
|
Notes:
|
||
|
|
|
||
|
|
This is an app specific shim.
