Hi Ricard, I am also working on csla membership with umbraco and having similar difficulties trying to extend Application_Start

but having a go.. let us know if you make progress.

Thanks

Digby

Hello Digby,

I made a temporary solution that consists in putting the desired Application_Start code in the Init() method of an HttpModule that you can add.

To add an HttpModule you can check this:

http://msdn.microsoft.com/en-us/library/ms227673%28VS.80%29.aspx

I made this since the Init() is executed more or less the same times as the Application_Start()

hope it helps,

let me know if you have any other solution,

Regards,

Ricardo

The global.asax.cs is compiled into a dll App_global_asax.dll which is shipped with umbraco

Below is the global.asax.cs from the 4.0.2.1 release. You can see its almost empty. (i removed all code commented out). The solution is to delete App_global.asax.dll in your umbraco distribution and make your own global.asax.cs. I did not test this myselve, but I was confronted with this today when I tried to make log4net working on a test server (eventually that log4net can also be initiated by a HttpModule). The following blog of Ismael also states that the App_global.asax.dll may be deleted from your bin directory.

A better solution is that in umbraco the events in the global.asax.cs can be handled by your own code. That is something the core-team might think about :-)

Just make your class inherit from the umbraco.Global, that should work.

Alternative create a HttpHander (inherit IHttpHandler) and then you have the request life cycle at your finger tips

@slace: can you give me an example on how to override the Application_start by inheriting unbraco.Global?

You should be able to do:

protected new void Application_Start(object sender, EventArgs e) { ... }

But really, you're better off writing your own HttpHandler, it's much more portable that way.

@slace

tried the above - but stille nothing happens (no log entry is written) - has the umbraco functionality changed - I'm on 4.7RC

Public Class MyGlobalEvents

 Inherits umbraco.Global

Protected Overrides Sub Application_Start(ByVal sender As Object, ByVal e As System.EventArgs)

Log.Add(LogTypes.Debug, -1, "Vi har kaldt application START by umbraco.global")

MyBase.Application_Start(sender, e)

End Sub

end Class

What is it that you're trying to do, log the application start? Don't bother, it's already being logged.. This is one such entry:

id userId  NodeId  Datestamp   logHeader   logComment
91920   0   -1  2010-08-31 10:30:51.597 System  Application started at 31-8-2010 10:30:51

As slace says, much better to do what you're trying to do using a HttpHandler or HttpModule.

Well yes thank you ;-) - I know it's being logged already - I just inserted that line to see if MY application_start code was being triggered (which it is not).

I wan't to start a timer which gathers performance parameters from the server at regular intervals. I have implemented this at a standard asp.net application which works beautifully - but Umbraco sites are a world apart...

I have tried all kinds of techniques (from this forum) to catch the application_start but to no avail - I have tried overriding the umbraco.global, applicationBase, system.Web.HttpApplication but nothing seems to work...

(some of the methods are theroretical I suspect - and not tried out) - so have anyone actually gotten this to work in umbraco 4.7 and how?

Alright, did you remember to actually delete the existing App_global.asax.dll and have you put your own dll in the bin folder to replace the functionality? Is there no actual global.asax file still inheriting from umbraco.Global?

Maybe add a global.asax that inherits from MyGlobalEvents (add your namespace before that if you have one).

The implementation hasn't changed much in 4.7, it's even less code then it was before.

Yes have deleted app_global.asax.dll and global.asax.cs (and global.asx.vb) from the app_code

I am copying my own NewTV2Bornholm.dll to the bin folder (using post build events in visual studio) this dll contains all my user controls and classes

I will look into the sourcecode you linked to .... Umbraco Shall Not Beat Me :-D

@Sebastiaan

just noticed that I don't have the  log entry from the application_end in your quoted source code in my log either....

something strange is going on (or is that because i've deleted the app_global.asax.dll)

I've just tried with an older version of Umbraco and it looks like this never actually worked anyway. I can't even find where the App_Global.asax.dll is generated from the umbraco source. I still get the default "application has started" message in the log, even after deleting the dll.

Sorry that I can't be of more help! 

Did you change the inherits attribute in your global.asax?

Umbraco has a class inheriting HttpApplication, umbraco.Global, which it tried to run by default.

But yes, I've seen a number of issues trying to override global.asax, you're better off creating a HttpModule to do what you need

All Right success at last:

Created a httpModule:

'  the class MUST also be added to the web.config under "configuration", "system.webServer", "modules" to work
Public Class MyGlobalEvents     Implements IHttpModule

    Public Sub Init(ByVal application As HttpApplication) Implements IHttpModule.Init
        Log.Add(LogTypes.Debug, -1, "Vi har kaldt application INIT by IHttpModule")
        If IsNothing(TV2BGlobal.appglobalObjConnectionPerfCounter) Then
            TV2BGlobal.appglobalObjConnectionPerfCounter = New TV2BGlobal.UserStatistik
        End If
    End Sub

    Public Sub Dispose() Implements System.Web.IHttpModule.Dispose
    End Sub
End Class

IMPORTANT: and added this to the web.config (newTV2Bornholm is the namespace) the place where this must be added is different depending upon your IIs version - mine is 7 in integrated mode (see this for more info: http://msdn.microsoft.com/en-us/library/ms227673.aspx):

<add name="MyGlobalEvents" type="NewTV2Bornholm.MyGlobalEvents, NewTV2Bornholm" />

and this is tested and works in umbraco 4.7.

However the INIT seems to fires several times during the lifetime of the application - so I needed to limit the number of instances of my global stat (which I only want ONE of for the entire app regardless of number of users and other variables)

Well, I managed to do it now by using visual studio's add dialog and choosing global.asax, this gives you a default global.asax.

But I would really go the route that Aaron is suggesting, create an httpModule, as an example look at umbraco's own umbraco.presentation.requestModule. Don't forget to add it to the web.config and you're good to go. And you can still upgrade Umbraco without worries.

Oh, posting at the same time! :-) 

Well, I don't know about your init but Umbraco's only fires once, so have a look at the link in the previous post anyway.
