Night Era II - Auto-Wake-Up

Version 2 of Night Era serve people who use their computers to listen to music before sleeping and also work as alarm to wake you up at morning, It contain a new future in which computer state will change to hibernate or suspend state at a specified time and wake up from that state when the wake up time is come to listen to music at early morning. below is the scenario of usage. While sleeping the master volume control value will be decreased to provide quietude. you can specify the interval of decreasing the volume control value i.e. each "N" minute the volume will decreased with 5 degree. so the volume will be lower along the sleeping time. You can specify the sleeping and waking up time, the wake up timer will wake up your computer from hibernate or suspend state. When the system time match the sleeping time, system state will change to either hibernate or suspend. When the system time match the wake up time, system will resume, and play a music file or MP3 list. The point of interests is that auto wake up functionality, that allow you to save power by putting the system in low power consuming state, and allow the system resume at morning to wake you up, also I search the web for a waitable timer in C# and I didn't find a one, so I build my own auto-wake-up-timer.
