<p><strong>Description:</strong></p>
<p>The <code>Import</code> method imports a contact to a contacts
database. The information must be imported from a vCard file.</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-F1C1F991-A130-4AF1-8A26-C73E9B6FEE1D">result = so.IDataSource.Import(criteria);</pre>

<p>For asynchronous calls:</p>
<pre class="codeblock" id="GUID-134F0C4F-3A91-464E-8E5C-A6D2014AEDF5">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 contact to import and optionally
the target database. For more information about the object properties and
how to define them, see section <a href="GUID-F631E6D3-AA0A-4C4E-95C4-13F9CA3F8AFF.html#GUID-F631E6D3-AA0A-4C4E-95C4-13F9CA3F8AFF">Criteria for importing a contact</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 an error code and an error message.</p>
<p>If asynchronous, the method returns an object that contains a transaction
ID for the <a href="GUID-C7C3B541-8D28-4DC6-9003-ECF57F26C608.html#GUID-C7C3B541-8D28-4DC6-9003-ECF57F26C608"><code>callback</code></a> instance,
an error code, and an error message. When the asynchronous call has completed, <code>callback</code> returns
an object that contains an error code and an error message (see <a href="GUID-C7C3B541-8D28-4DC6-9003-ECF57F26C608.html#GUID-E43BC9EA-3EBE-4C7F-A57E-A1C33BB01CF4">Table: Callback return value</a>).</p>

<p><strong>Remarks:</strong></p>
<ul>
<li><p>The default contacts database is <code>cntdb://c:contacts.cdb</code>.</p>
</li>
<li><p>If the contacts database is specified, the contact is imported
there. If no database is specified, the default database is used. If the default
database does not exist, it is created and the contact is imported there.</p>
</li>
<li><p>SIM card databases only support name and number keys for
vCard.</p></li>
