下面，我们用这个“注册表”类来写一个简单的“计数器”应用，代码如下：
pagecount.asp:
<!-- #Include File="registry_class_inc.asp" -->
<%
Dim Reg
Set Reg = New RegistryObject
Reg.Path = Server.MapPath("pagecount.xml")
Const BaseCount = 8000 '计数器基数
Dim Count
Count = Reg.ReadValue("Pagecount", "Common", "Count") '读取原有计数
If IsNumeric(Count) Then
Count = CLng(Count)
Else
Count = BaseCount
End If
If Count < BaseCount Then Count = BaseCount
Count = Count + 1
Reg.SaveValue "Pagecount", "Common", "Count", Count '保存新计数
Set Reg = Nothing
Response.Write("document.write ('您是第 " & Count & " 位来访者');") ' 显示计数
%>
