+<p><strong>Description:</strong></p>
+<p>The <code>Add</code> method adds an event (entry) to the event
+log database.</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-7CD9AD3A-D065-4F76-A3FF-D524249CBF65-GENIDd0e51563">result = so.IDataSource.Add(criteria);</pre>
+
+<p>For asynchronous calls:</p>
+<pre class="codeblock" id="GUID-F1140A2E-9B60-4953-8C6E-1A6C47461241-GENIDd0e51569">result = so.IDataSource.Add(criteria, callback);</pre>
+
+<p><strong>Arguments:</strong></p>
+<ul>
+<li><p><code>criteria</code>:</p>
+
+<p>This is an object that specifies what type of device log entries are
+added to the event database and details about the entry. For more information
+about the object properties and how to define them, see section <a href="GUID-DDF5BDA7-E0DA-40EB-94E7-30824B0F4365.html#GUID-DDF5BDA7-E0DA-40EB-94E7-30824B0F4365">Criteria for adding a log entry</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>Add</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>Add</code> call.</p>
+
+</li>
+</ul>
+<p><strong>Return value:</strong></p>
+<p>If synchronous, the <code>Add</code> method returns an object
+that contains a unique identifier for the log entry, an error code, and an
+error message.</p>
