Physical Application Path in Application_End

[Alphonse Giambrone]

How can I get the physical application path in the Application_End event?
I need it to periodically compact a database and it seems that the request,
application and server objects are not available at that point.

Hi Alphonse,

Here's one way to do it. Place these functions in your global.asax file.

Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs)
Dim di As System.IO.DirectoryInfo
di = System.IO.Directory.GetParent(Server.MapPath("web.config"))
Application("path") = di.FullName
End Sub

Sub Application_End(ByVal sender As Object, ByVal e As EventArgs)
'To get the string, just use Application("path")
Dim s As String = Application("path")

'Since you can't watch the application end event,
'this code writes the string to a file where you
'can see it. This is only for test purposes and
'you will need to temporarily grant the ASPNET
'account full permissions to the folder, in this
'case C:\Inetpub\wwwroot\test1.
Dim file As New
System.IO.StreamWriter("C:\Inetpub\wwwroot\test1\test.txt")
file.WriteLine(s)
file.Close()
End Sub

Does this answer your question?

Thanks for the quick reply Mike.
Based on this, is seems I have misidentified the location of my problem.
I do store the value in an application variable, but because I use it in
several places in the app, I retrieve it from a public function in another
module via HttpContext.Current.Application("path"). This was the only method
I found to gain access to application variables in a module or class.
In Application_End I am actually calling a function in another module that
is compacting the db and updating a field in the db. This function retrieves
the path from the other function.
I knew it was failing due to not being able to retrieve Application("path")
so I incorrectly assumed that application vars were not available in
Application_End.
After trying your example, I see that I was wrong and my real problem is
that they are not available in another module/class once Application_End
fires via HttpContext.Current.Application since it is nothing at that time.

So, what I really need is a method to access the application variables from
another module or class once Application_End fires.
Is this possible?

Hi Alphonse,

My first recommendation is to extract the values from the application
object from within the Application_End event. Then pass the values as
parameters.

I also tried a public variable in a module and it worked. Here's the code.

Public Class Global
Inherits System.Web.HttpApplication

Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs)
Dim di As System.IO.DirectoryInfo
di = System.IO.Directory.GetParent(Server.MapPath("web.config"))
Module1.AppPath = di.FullName
End Sub

Sub Application_End(ByVal sender As Object, ByVal e As EventArgs)
Module1.WriteAppVar()
End Sub
End Class

Module Module1

Public AppPath As String

Public Sub WriteAppVar()
Dim file As New
System.IO.StreamWriter("C:\Inetpub\wwwroot\test1\test2.txt")
file.WriteLine(AppPath)
file.Close()
End Sub
End Module

Thanks Mike.
That will work.
Just for my knowledge. Am I correct in that you are confirming that
application variables are not available outside global.asax once
Application_End has fired?
