This example shows how to use the AdRotator component to display a different advertisement
image, each time a user visits
or refreshes the page.</p>
<p><a target="_blank" href="showasp.asp@filename=demo_adrotator2">AdRotator - The Images are
Hyperlinks</a><br />
This example shows how to use the AdRotator component to display a different advertisement
image, each time a user visits
or refreshes the page. In addition, the images are hyperlinks.</p>
<hr />
<h2>ASP AdRotator Component</h2>
<p>The ASP AdRotator component creates an AdRotator object that displays a
different image each time a user enters or refreshes a page. A
text file includes information about the images.</p>
<h3>Syntax</h3>
<table class="ex" cellspacing="0" border="1" width="100%" cellpadding="3">
<tr valign="top">
<td><%<br />
set adrotator=server.createobject("MSWC.AdRotator")<br />
adrotator.GetAdvertisement("textfile.txt")<br />
%></td>
</tr>
</table>
<br />
<hr />
<h2>Example</h2>
<p>Assume we have a file called "banners.asp". It looks like this:</p>
<table class="ex" cellspacing="0" border="1" width="100%" cellpadding="3">
<tr valign="top">
<td><html><br />
<body><br />
<%<br />
set adrotator=Server.CreateObject("MSWC.AdRotator")<br />
response.write(adrotator.GetAdvertisement("ads.txt"))<br />
%><br />
</body><br />
</html></td>
</tr>
</table>
<p>The file "ads.txt" looks like this:</p>
<table class="ex" cellspacing="0" border="1" width="100%" cellpadding="3">
<tr valign="top">
<td>
*<br />
w3schools.gif<br />
http://www.w3schools.com/<br />
Visit W3Schools<br />
80<br />
microsoft.gif<br />
http://www.microsoft.com/<br />
Visit Microsoft<br />
20
</td>
</tr>
</table>
<p>The lines below the asterisk in the file "ads.txt" specifies the images to be displayed, the
hyperlink addresses, the alternate text (for the images), and the display rates in percent of the
hits. We see that the W3Schools image will be displayed for 80 % of
the hits and the Microsoft image will be displayed for 20 % of the hits in the
text file above.</p>
<p><b>Note:</b> To get the links to work when a user clicks on them, we will
have to
modify the file "ads.txt" a bit:</p>
<table class="ex" cellspacing="0" border="1" width="100%" cellpadding="3">
<tr valign="top">
<td>
REDIRECT banners.asp<br />
