<p><strong>Description:</strong></p>
<p>The <code>Import</code> method imports entries into a calendar.
The information must be imported from an iCal or vCal file. For more information
about these two formats, see the <a href="GUID-AE9A928B-F938-49B5-BC9E-72CB42046571.html#GUID-AE9A928B-F938-49B5-BC9E-72CB42046571">Calendar
Service overview page</a>.</p>
<p>This method can be called both synchronously and asynchronously.</p>
<p><strong>Syntax:</strong></p>
<p>For synchronous calls:</p>
<pre class="codeblock" id="GUID-173FE57C-5F1D-45F7-A3A3-83CA5A05D0A5">result = so.IDataSource.Import(criteria);</pre>

<p>For asynchronous calls:</p>
<pre class="codeblock" id="GUID-141D4B72-7957-49FD-AC57-C785FC5E7A55">result = so.IDataSource.Import(criteria, callback);</pre>

<p><strong>Arguments:</strong></p>
<ul>
<li><p><code>criteria</code>:</p>

<p>This is an object that specifies the calendar entries to import and
optionally the target calendar. For more information about the object properties
and how to define them, see section <a href="GUID-B86F1686-F2AC-438F-8306-4B9D70F879EC.html#GUID-B86F1686-F2AC-438F-8306-4B9D70F879EC">Criteria for importing calendar entries</a>.</p>

</li>
<li><p><code>callback</code>:</p>

<p>The <code>callback</code> argument is the name of the method
that is executed when an asynchronous <code>Import</code> call has
results or status information to return. You must define this method separately.
Follow the instructions in section <a href="GUID-C7C3B541-8D28-4DC6-9003-ECF57F26C608.html#GUID-C7C3B541-8D28-4DC6-9003-ECF57F26C608">Defining the callback handler for an asynchronous method</a> to
define the <code>callback</code> method.</p>
<p>This argument is used only with an asynchronous <code>Import</code> call.</p>

</li>
</ul>
<p><strong>Return value:</strong></p>
<p>If synchronous, the <code>Import</code> method returns an object
that contains a list of the imported calendar entries, an error code, and
an error message.</p>
