ok I used the global.asax page for this one, got this information off www.4guysfromrolla.com, good site.
Sub Application_Start(ByVal sender AsObject, ByVal e As EventArgs)
'This variable Hits will store the # of visitors
Application("Hits") = 0
EndSub
Sub Session_Start(ByVal sender AsObject, ByVal e As EventArgs)
'Lock the Application for concurrency issues
Application.Lock()
'Increment the counter
Application("Hits") = Application("Hits") + 1
'Unlock the Application
Application.UnLock()
EndSub
Now to declare it in my webform...
This page has been viewed
<%=application("Hits")%>
times.
Ok guys, this works but I would not by any means recommend it because it resests itself every time you rebuild the project, plus it resets whenever the server your site is on reboots or restarts, if anyone has a better alternative to this, please let me know. The next question I have is how do I replace the number on the hit counter, with a graphic, say it said 2 people have visited the page in plain text, I want that "2" to be an image of a 2, I've found a little on this but it's not working. Will post back if I find anything out.

Are you fermiliar with GDI+ in .NET? What you need to do is make a dynamic image. Make a new webform, give it an image content type, and in the page's code, create the graphic (using the hitcount you want), do a Response.Flush(), and then then write the Graphic using Response.Write (Maybe WriteStream). Then, in your webpage, just do <img> tags to your dynamic image webform ;-).

Also, to make the hitcount perminate, you'll want to use a file, a database, or registry key to keep track of the hitcount ;-).

Ok, I have been trying to find where I can make a vb.net perminant hit counter, most are by using text files (and I would definitely prefer them over a database). My problem now is, I can't find any code to make one! The little code I can find is poorly explained and I was wondering if one of you guys could maybe help me out here. God Bless!:cry:

Fixed this one also guys. Here is the code for my hit counter. There was also some code to create .gif images for the number images on the fly but... it proved a little difficult, I'll probably put them in version two of the website. The company website is nearly up 
the boss loves it, I'll keep you guys updated so I can get some feedback on my work, thanks! Here is the code
and of course, don't forget the "Imports System.IO" (no quotations) at the top of the code. Happy coding guys! Thanks again Tekmaven!

Here is the codePrivateSub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) HandlesMyBase.Load IfNot Page.IsPostBack Then Dim nCount As Int32 = 0 nCount = GetCounterValue() lblTest.Text = nCount.ToString() EndIf EndSub PrivateFunction GetCounterValue() As Int32 Dim ctrFile As StreamReader Dim ctrFileW As FileStream Dim sw As StreamWriter Dim strPath AsString = Server.MapPath("indexcount.txt") Dim strCounterContents AsString Dim nCounter As Int32 If (File.Exists(strPath)) Then ctrFile = File.OpenText(strPath) strCounterContents = ctrFile.ReadLine().ToString() ctrFile.Close() nCounter = Convert.ToInt32(strCounterContents) Else nCounter = 0 EndIf nCounter += 1 ctrFileW = New FileStream(strPath, FileMode.OpenOrCreate, FileAccess.Write) sw = New StreamWriter(ctrFileW) sw.WriteLine(Convert.ToString(nCounter)) sw.Close() ctrFileW.Close() Return nCounter EndFunction

But how to do the same in C#. For instance :
int hits = Int32.Parse(Application["Hits"]);
Will create a error
Error 2 Argument '1': cannot convert from 'object' to 'string' E:\Sh\ASP\cS HitCounter\Global.asax 26 32 E:\...\cS HitCounter\
int hits = Int32.Parse(Application["Hits"]);
Will create a error
Error 2 Argument '1': cannot convert from 'object' to 'string' E:\Sh\ASP\cS HitCounter\Global.asax 26 32 E:\...\cS HitCounter\

int hits = Int32.Parse(Application["Hits"].ToString());
but
int hits = (int)Application["Hits"];
would be better because the object is already an int
Write this code to your global.asax
Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs)
Application.Lock()
Application("counter") = Application("counter") + 1
Application.UnLock()
End Sub
and write these lines in your default homepage
<%
Application.Lock()
Application("counter") = CType(Application("counter") + 1, Int32)
Application.UnLock()
%>
Everything will be fine then.
Enjoy the weekend.
