.net asp vb hit counter

[tbuchli]

I'm trying to make a hit counter. I have it working but when I add it to my website, I get a web config. error...

    CodeFile="Default.aspx.vb" Inherits="_Default" %>

                nCount = GetCounterValue()
                lblHitCount.Text = nCount.ToString()
            End If

        End Sub

        Private Function GetCounterValue() As Int32

            Dim strCounterContents As String
            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

            End If

            nCounter += 1
            ctrFileW = New FileStream(strPath, FileMode.OpenOrCreate, FileAccess.Write)

I get this error:

Server Error in '/' Application.

Runtime Error

Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine. 

Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".


<!-- Web.Config Configuration File -->

<configuration>
    <system.web>
        <customErrors mode="Off"/>
    </system.web>
</configuration>

Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.


<!-- Web.Config Configuration File -->

<configuration>
    <system.web>
        <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
    </system.web>
</configuration>

The error is telling you that if you want to see the actual error, turn custom errors to OFF or remotely only but with remote only you would only see the error is browsing from the webserver itself.

Just temporarily set it to off so you can get the details.

I realize that, but why won't it run? It works when I run it from VS...

did you upload indexcount.txt?

edit: hmm, you did a check for that...
you might have to turn on debug for a min. is that an option?

edit 2: i don't have a ton of experience with IO but what do you get when you read an empty file? did you upload a 'fresh' empty text file? maybe you're trying to convert an empty string to int32?

I did upload indexcount...

edit 2: I do not think this is the case...
