// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// This example uses a previously obtained access token having permission for the 
// Google Calendar scope.

// In this example, Get Google Calendar OAuth2 Access Token, the access
// token was saved to a JSON file.  This example fetches the access token from the file..

// Build a Google Calendar event:
Chilkat.JsonObject json = new Chilkat.JsonObject();
json.EmitCompact = false;
json.UpdateString("kind","calendar#event");
json.UpdateString("summary","Eat Lou Malnati's Pizza");
