I haven't tested all of this, but you could try re-throwing the exception.

Catch ex as exception
    CreateLogFile(Ex)
    Throw
End Try

Then, to handle that, add a new "Global Application Class" to your solution. Visual Studio should then create a new file, Global.asax. In its code behind, do something like:

Public Class Global
    Inherits System.Web.HttpApplication
    Protected Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs)
        Server.Transfer("~/Error.aspx")
    End Sub
End Class

The benefit of that is it will catch any uncaught exceptions. So then, once in Error.aspx, or whatever:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
    Dim ex As Exception = Server.GetLastError()
    If ex Is Nothing Then
        'Can't determine last error
    Else
        ex = ex.GetBaseException()
        
        If ex Is Nothing Then
            'Can't determine last error
        Else
            'Display error message
        End If
    End If
End Sub

^ For some reason the syntax highlighting javascript is taking those comments as strings.

After you call your CreateLogFile method, then you would issue a Response.Redirect or Server.Transfer to your error page
