     7 <p><strong>Description:</strong></p>
       
     8 <p>The <code>GetList</code> method retrieves a list of contacts,
       
     9 contact groups, or contacts databases. Contacts and contact groups are retrieved
       
    10 from the specified contacts database or, if no database is specified, from
       
    11 the default one.</p>
       
    12 <p>This method can be called both synchronously and asynchronously.</p>
       
    13 <div class="note"><p><strong class="note_title">Note: </strong>Calls that retrieve a list of databases must always be synchronous.</p>
       
    14 </div>
       
    15 <p><strong>Syntax:</strong></p>
       
    16 <p>For synchronous calls:</p>
       
    17 <pre class="codeblock" id="GUID-5017A498-4BF1-48C1-B6AD-44DB3DC7436E">result = so.IDataSource.GetList(criteria);</pre>
       
    18 
       
    19 <p>For asynchronous calls:</p>
       
    20 <pre class="codeblock" id="GUID-22320C1F-DC1F-4D35-BDFE-25E12DA64321">result = so.IDataSource.GetList(criteria, callback);</pre>
       
    21 
       
    22 <p><strong>Arguments:</strong></p>
       
    23 <ul>
       
    24 <li><p><code>criteria</code>:</p>
       
    25 
       
    26 <p>This is an object that specifies what contact information is returned
       
    27 and how the returned information is sorted. For more information about the
       
    28 object properties and how to define them, see section <a href="GUID-06C803FE-DD16-44B5-B9C7-2EC9D497D425.html#GUID-06C803FE-DD16-44B5-B9C7-2EC9D497D425">Criteria for retrieving contact information</a>.</p>
       
    29 
       
    30 </li>
       
    31 <li><p><code>callback</code>:</p>
       
    32 
       
    33 <p>The <code>callback</code> argument is the name of the method
       
    34 that is executed when an asynchronous <code>GetList</code> call has
       
    35 results or status information to return. You must define this method separately.
       
    36 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
       
    37 define the <code>callback</code> method.</p>
       
    38 <p>This argument is used only with an asynchronous <code>GetList</code> call.</p>
       
    39 
       
    40 </li>
       
    41 </ul>
       
    42 <p><strong>Return value:</strong></p>
       
    43 <p>If synchronous, the <code>GetList</code> method returns an object
       
    44 that contains the requested contact information, an error code, and an error
       
    45 message.</p>
