XML + application to compile counters (1)

1) Total Website Visitors counter

We can use XML to implement this type of counter. Open the windows notepad and enter the following data as count. xml.

<Mycount>

<Allcount> 0 </allcount>

<Maxcount> 0 </maxcount>

</Mycount>

The allcount tag records the total number of web page visits.CodeManipulate this XML file

<% @ Import namespace = "system. Data" %>

<% @ Import namespace = "system. Data. oledb" %> // import...

<Script language = "C #" runat = Server>

Httpcookie ckecount = new httpcookie ("count"); // a cookie variable used to determine whether a visitor is on your website

Void page_load ()

{

If (request. Cookies ["count"] = NULL) // If the cookie is empty, it indicates that your page is loaded for the first time.

{

Ckecount. value = "true"; // Add a value to the cookie

/* Here is an optional code to check whether the cookie is invalid. If you set it to one month, a visitor has visited your site before, and his cookies contain the value you saved, in addition, if the cookie is not cleared, the visitor will not add 1 to the counter when loading the page. If you do not set the cookie retention time, then, when a visitor leaves your site, the cookie disappears automatically.

Datetime dt = datetime. now;

Timespan Ts = new timespan (30, 0, 0, 0 );

Ckecount. expires = DT + ts;
