<p>Messaging API gives you an easy and powerful tool for remote code execution. The short overview of the API is in <a href="../messaging.html" class="wikiLink">Messaging chapter</a>. </p>
<p>All you will need to do is to define specific message class or classes (should be shared between client and server).</p>
<p>The client side can issue messages using:</p>
<span name="cs_wiki_filter" csw_filters="cs">
<p>c#: <code>IMessageSender#Send(message) </code></p>
</span>
<span name="cs_wiki_filter" csw_filters="vb">
<p>VB: <code>IMessageSender#Send(message) </code></p>
</span>
<p>The server side should register a message listener:</p>
<span name="cs_wiki_filter" csw_filters="cs">
<p>c#: <code>Configuration#SetMessageRecipient(IMessageRecipient)</code></p>
</span>
<span name="cs_wiki_filter" csw_filters="vb">
<p>VB: <code>Configuration#SetMessageRecipient(IMessageRecipient)</code></p>
</span>
Message recipient should define a response to the different messages received in
<span name="cs_wiki_filter" csw_filters="cs">
<p>c#: <code>ProcessMessage(IObjectContainer objectContainer, object message) </code></p>
</span>
<span name="cs_wiki_filter" csw_filters="vb">
<p><code>vb: ProcessMessage(ByVal objectContainer As IObjectContainer, ByVal message As Object) </code></p>
</span>
<p>method. ObjectContainer parameter gives full control over the database.</p>
<p>Let's reset our database and try updating using special UpdateServer message.</p>
