Log:
[SNDVOL32]
- Implement retrieving current volume level and mute state and set the dialog controls on
startup
- Remove last line separator from GUI
- Implement updating slider / switch control when another application modifies volume
settings
- Implement writing current selected lines settings into registry when the preference
dialog is closed
- Implement helper functions which receive / set volume level
- Sndvol32 is now fully functional and has been tested in Windows XP SP3
- TODO: implement support for setting volume balance (left - right slider)
- TODO: Resources have not yet been commited
