Google calendar is one of the best free tool for tracking
your day to day appointment and reminder for your rest of schedule. There are facilities
for reminder with email and sms that will enable you for preparing your next
meeting/appointment.
We can leverage this tool in our any of application, we can
sync our event or appointment with google calendar so one may miss reminder
from application but alternatively get from google calendar.
Doesn’t it seem cool? Even implementation is simpler than it
seem.
Firstly, you will need to add reference of following files.
using Google.GData.Client;
using Google.GData.Extensions;
using Google.GData.Calendar;
You can find those files here.
Below is code block for adding event in google calendar.
public CalendarService
GetService(string applicationName, string userName, string
password)
{
CalendarService service = new
CalendarService(applicationName);
service.setUserCredentials(userName, password);
return service;
}
public static void AddEvent(CalendarService
service, string title, string
contents, string location, DateTime startTime, DateTime
endTime)
{
Google.GData.Calendar.EventEntry
entry = new Google.GData.Calendar.EventEntry();
// Set the title
entry.Title.Text = title;
//Set event details.
entry.Content.Content = contents;
// Set a location for the event.
Where eventLocation = new
Where();
eventLocation.ValueString = location;
entry.Locations.Add(eventLocation);
//Set starting time and end time for the event.
When eventTime = new
When(startTime, endTime);
entry.Times.Add(eventTime);
Uri postUri = new Uri("https://www.google.com/calendar/feeds/aslam.h.net@gmail.com/private/full");
// Send the request and receive the response:
AtomEntry insertedEntry = service.Insert(postUri,
entry);
}
Here, GetService method will take
three parameters named application name, username and password.
Application name can be any name, you
wish. Username is your google account name where you have configured your calendar
and wish to sync with that calendar. Password is your google account password.
Method will return back calendar service
object. We can use this service object anywhere for using any service
associated with calendar.
Method AddEvent: this method will add event in any our calendar. Most of
statements are formatted with comments.
There is one critical statement you
need to take care.
Uri postUri = new Uri("https://www.google.com/calendar/feeds/shailesh@gmail.com/private/full");
Please note that one dynamic part, shailesh@gmail.com. It’s my calendar’s id. You can easily find your
sync calendar id with following steps.
1) Logon to
your gmail account and click on calendar link at top bar, it will open up your calendar
in new tab.
2) On the
right side, there will be section named “My Calendars”. It lists out calendars,
you created. You can create more than one calendar in google calendar tool.
3) Go to any
of calendar, click on the arrow. It will show one menu. Click on “Calendar settings”.
4) There will
be one row with “Calendar Address”,
most probably before last row. Just look around this row, there will be
information like this.
(Calendar ID: shailesh @gmail.com)
This is the address for your calendar. No one
can use this link unless you have made your calendar public
That’s it.
I hope this will enable to sync your important tasks, appointment
and meeting with google calendar.
Happy scheduling appointment
