Schedualed Recording

The calendar control has reminders feature.
a) When you set reminder for calendar event -- OnReminders notification will be fired.
b) When you receive OnReminders for some event, start recording.
c) Use event EndTime property to monitor when stop recording.
d) Also disable reminder for started event.
 
See our sample application.
 
Note that Calendar monitors reminders only while it is running.

Another way is use windows scheduled tasks. On calendar events create/change/delete add/update corresponding job in windows scheduled tasks. In this case scheduled tasks will be performed independently. Your application will have own user interface to manage these jobs. Also you need some app which will be runned by these jobs.

For MFC version see for notification XTP_NC_CALENDAR_ON_REMINDERS.

I was actually talking about VB sample :)

But take a look at CalendarDemo MFC sample, look into CalendarDemoView.cpp for how it handles this notification.

You'll have to uncomment a few lines -- search for them with OnReminders keyword.

Yep, for sure. This is just a property which stores a time value.
