<p><strong>Description:</strong></p>
<p>The <code>Add</code> method creates a new calendar on the device
or adds an entry to a calendar. In the latter case, if an entry with the same <code>LocalId</code> already
exists in the calendar, it is modified accordingly. You can thus use this
method to both add and update calendar entries. The entry is added to the
specified calendar or, if no calendar is specified, to the default one. If
the default calendar does not exist, it is created.</p>
<p>This is a synchronous method.</p>
<p><strong>Syntax:</strong></p>
<pre class="codeblock" id="GUID-0EE18D9D-227E-4F3E-B727-747F9EB2FE05">result = so.IDataSource.Add(criteria);</pre>
<p><strong>Arguments:</strong></p>
<ul>
<li><p><code>criteria</code>:</p>
<p>This is an object that specifies the calendar to create or the calendar
entry to add or update. For more information about the object properties and
how to define them, see section <a href="GUID-54013A2F-7503-4DA3-85C7-904BCD98B011.html#GUID-54013A2F-7503-4DA3-85C7-904BCD98B011">Criteria for adding and updating calendar information</a>.</p>
</li>
</ul>
<p><strong>Return value:</strong></p>
<p>The <code>Add</code> method returns an object that contains
an error code and an error message. In addition, if a calendar entry was added
or updated, the result object contains the <code>id</code> of that
entry.</p>
