How to obtain the number of events scheduled for a given date

Description:
I'm trying to show the number of events for each day in the day header. Is there a function which will quickly return an event count for each day?

Answer:
You can use the Scheduler Storage's GetEvents function. For example:

Delphi
uses  
 DateUtils;  // for OneSecond  
...  
var  
 AList: TcxSchedulerFilteredEventList;  
...  
 AList := TcxSchedulerFilteredEventList.Create;  
 try  
   if <Storage>.GetEvents(AList, Date + OneSecond, Date + 1 - OneSecond) then  
     Caption := IntToStr(AList.Count) + ' events.'  
   else  
     Caption := 'No events.';  
 finally  
   AList.Free;  
 end;  

For more details, please refer to the ExpressScheduler's documentation.
IMPORTANT: It's necessary to add and subtract 1 second from the compared time. Since the TDateTime type is actually Double, it's necessary to take the Double type precision into account. You can use the OneSecond constant declared in the DateUtils unit.
