<p><strong>Description:</strong></p>
<p>The <code>Export</code> method exports a contact from a contacts
database. The information is exported to 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-34DA0408-CEF1-45A8-A9BE-7374FD7D94C6">result = so.IDataSource.Export(criteria);</pre>
<p>For asynchronous calls:</p>
<pre class="codeblock" id="GUID-C2FBCD68-0924-42CE-836C-69F4A1ADEF3B">result = so.IDataSource.Export(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 export and optionally
the source database. For more information about the object properties and
how to define them, see section <a href="GUID-92D152D3-E29A-4010-B5A0-9D37A0369A21.html#GUID-92D152D3-E29A-4010-B5A0-9D37A0369A21">Criteria for exporting 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>Export</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>Export</code> call.</p>
</li>
</ul>
<p><strong>Return value:</strong></p>
<p>If synchronous, the <code>Export</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>
