ASP set up Web page counters

web| Counter | page using ASP to build a Web page counter usually has two simple methods, one is to establish Global.asa, the other is to write an ASP file to count. Generally use a document to save the browsing quantity.

1, with Global.asa to write counters write a Global.asa file, stored in the root directory of the virtual directory, the source code is as follows:

<script language = "Vbscript" runat= "Server" >
Sub Application_OnStart ()
Countfile=server.mappath ("counter") + "/counter.txt"
Set Fso=server.createobject ("Scripting.FileSystemObject")
Set FILE=FSO. OpenTextFile ("Countfile")
\ ' Read access and assign to application variable number
Application ("number") =file.readline
File.close
End Sub
Sub Session_OnStart ()
If IsEmpty (Session ("hasbeenconnected")) Then
Application.Lock
Application ("number") =application ("number") +1
Applicaiotn.unlock
End If
Session ("hasbeenconnected") =true
End Sub
Sub Application_OnEnd ()
Countfile=server.mappath ("counter") + "/counter.txt"
Set Fso=server.createobject ("Scripting.FileSystemObject")
Set FILE=FSO. CreateTextFile ("Countfile", True)
\ ' writes the current value using the WriteLine method
File.writeline (Application ("number"))
File.close
End Sub
</script>
Write <%response in the Web page when the counter is invoked. Write ("You are the first" &number& "Visitor!") %>, but the calling page must also be an ASP page. This method has disadvantages, is a lot of personal home page space does not support running Global.asa, that is, not a user-built virtual directory, so it does not run correctly.

2, directly write a counter.asp to count my own now use the counter is this, and can be called on any page, call the method is:

<scriptsrc= "http://xxx.xxx.xxx/counter.asp?id=abc&num=6&style=1" ></script >
Where ID=ABC indicates that the user name is ABC, the Counter/abc.txt store count value should be established;
Num=6 is the number of display digits of the counter;
Style=1 for counter style, the establishment of counter/style1/0~9.gif can be added to a variety of styles.

The source code is as follows:

<%
Set Fso=server. CreateObject ("Scripting.FileSystemObject")
Filepath=server.mappath ("counter") + "/" +request ("id") + ". txt"
Set Temp=fso.opentextfile (filepath,1)
Count=temp.readline
Temp.close
If IsEmpty (Session ("Connected")) then
Set Temp=fso.opentextfile (filepath,2)
Application.Lock
Count=count+1
Temp.writeline (count)
Application.UnLock
Temp.close
End If
Set temp=nothing
Set fso=nothing
Session ("Connected") =true
Numlength=len (count)
If request ("num") = "" Then
Maxnum=6
Else
Maxnum=cint (Request ("num")
End If
If request ("style") = "" Then
style= "1"
Else
Style=request ("style")
End If
For I=1 to Maxnum step 1
If I<=maxnum-numlength Then
Countimage= "</img>"
Response.Write "document.write (\ ' &countimage&"); "
Else
Countimage= "</img>"
Response.Write "document.write (\ ' &countimage&"); "
End If
Next
