<P>The <B>CreateObject </B>method creates an instance of a server component. If the component has implemented the <B>OnStartPage</B> and <B>OnEndPage </B>methods, the <B>OnStartPage </B>method is called at this time. For more information about server components, see <A HREF="/iishelp/iis/htm/asp/comp275c.htm">Installable Components for ASP</A>.</P>
<H6>Syntax</H6>
<P><B>Server.CreateObject(</B> <I>progID</I> <B>)</B></P>
<P><B>&nbsp;</B></P>
<H6>Parameters</H6>
<DL>
<DT><I>progID</I></DT>
<DD>Specifies the type of object to create. The format for <I>progID</I> is [<I>Vendor</I><B>.</B>]<I>Component</I>[<B>.</B><I>Version</I>].</DD>
</DL>
<H6>Remarks</H6>
<P>By default, objects created by the <B>Server.CreateObject</B> method have page scope. This means that they are automatically destroyed by the server when it finishes processing the current ASP page.</P>
<P>To create an object with session or application scope, you can either use the &lt;OBJECT&gt; tag in the Global.asa file and set the SCOPE attribute to SESSION or APPLICATION, or store the object in a session or application variable.</P>
<P>For example, an object stored in a session variable, as shown in the following script, is destroyed when the <A HREF="/iishelp/iis/htm/asp/vbob12d0.htm"><B>Session</B></A> object is destroyed. That is, when the session times out, or the <A HREF="/iishelp/iis/htm/asp/vbob5tpq.htm"><B>Abandon</B></A> method is called.</P>
<PRE><CODE>&lt;% Set Session("ad") = Server.CreateObject("MSWC.AdRotator")%&gt;
</CODE></PRE>
<P>You can also destroy the object by setting the variable to <CODE>Nothing</CODE> or setting the variable to a new value, as shown below. The first example releases the object <CODE>ad</CODE>. The second replaces <CODE>ad</CODE> with a string.</P>
<PRE><CODE>&lt;% Session("ad") = Nothing %&gt;
&lt;% Session("ad") = "some other value" %&gt;
</CODE></PRE>
<P>You cannot create an object instance with the same name as a built-in object. For example, the following returns an error.</P>
<PRE><CODE>&lt;% Set Response = Server.CreateObject("Response") %&gt;
</CODE></PRE>
<H6>Example</H6>
<PRE><CODE>&lt;% Set MyAd = Server.CreateObject("MSWC.AdRotator") %&gt;
</CODE></PRE>
<P>The preceding example creates a server component, <CODE>MyAd</CODE>, as a <B>MSWC.AdRotator</B> component that can be used to automate rotation of advertisements on a Web page. </P>
<P>For more information about server components, see the Platform SDK.</P>
