COMMENTS
You can still use the alarm capabilities of the object and not display the clock on your form by unchecking the Visible property (set to False).
EVENTS
This object has a single event that is called if you have checked the AlarmEnabled property and set the AlarmHour, AlarmMinute and AlarmSecond property values. This event looks to your program for a special label. It is made up of the object Name, a period (.) and the Event name (Ring). The full event name would be ObjectName.Ring:. You would not return a value from the program, just a simple RET is all that is required. So, if the alarm "rings" and if the event label exists, the routine is called, you return from the routine, and the user has control again.
