I got this:

public class AppEvents : IApplicationEventHandler {
        public void OnApplicationInitialized(UmbracoApplication httpApplication, ApplicationContext applicationContext) {

        }
        public void OnApplicationStarting(UmbracoApplication httpApplication, ApplicationContext applicationContext) {
            Document.AfterPublish += DocumentEvents.Document_AfterPublish;
            Document.AfterSave += DocumentEvents.Document_AfterSave;
        }
        public void OnApplicationStarted(UmbracoApplication httpApplication, ApplicationContext applicationContext) {

}

}

but my problem is it runs twice? so you got 2 times the same event.. if i set up a debugger i also got two hits. Dirk don't you have this problem? Have you got a example class you you did this?

Alright Dirk, thanks! Got this working, here's a paste from an answer I gave in another post from my experience with this. I put mine in OnApplicationInitialized, tomorow I'll test for what Edwin is bringing up, I don't think I've ran through these with my debugger, I'll give it a look!

usingSystem;
usingSystem.Linq;
usingUmbraco.Core;
usingUmbraco.Web;
using umbraco.BusinessLogic;
using umbraco.businesslogic;
using umbraco.cms.businesslogic;
using umbraco.cms.businesslogic.web;

namespaceMyNamespace
{
    publicclassNodeHooks:IApplicationEventHandler
    {

        publicvoidOnApplicationInitialized(UmbracoApplication httpApplication,ApplicationContext applicationContext)
        {
            Document.New+=DocumentNew;
            Document.AfterPublish+=AfterPublish;
        }

        publicvoidOnApplicationStarting(UmbracoApplication httpApplication,ApplicationContext applicationContext)
        {
        }

        publicvoidOnApplicationStarted(UmbracoApplication httpApplication,ApplicationContext applicationContext)
        {
        }

        staticvoidAfterPublish(Document sender,PublishEventArgs args)
        {
            if(sender.ContentType.Alias=="OfSomeType")
            {
                // Do stuff
            }
        }

        staticvoidDocumentNew(Document sender,NewEventArgs e)
        {
            if(sender.ContentType.Alias=="OfSomeType")
            {
                // Do stuff
            }
        }

    }
}

Thanks!

@Sebastien, does it work with your version? I still got this problem.

Hi Edwin,

Yes worked like I wanted still havent gotten around to cinfirm events only fire once, but I'm confident. Want to paste you code in here for us to take a look at what might be the problem?

(PS: I'll be away for 4 days, so if I don't write back it's not because I'm mean hah)

just look 3 post before this one, i've already posted it.

Well the difference is that you are hooking into publicvoidOnApplicationStartingand me publicvoidOnApplicationInitialized. There is probably a difference there, can you move it to publicvoidOnApplicationInitialized?

Doesn't change anything, i've tried already in all the different events but they alle start 2 times.

Hmm... That's quite strange, monday I can try a few things (I'm not at work), I guess this may mean that you application is starting twice? Sorry I can't help more :(

Is it too late to add question here? Where in the folder structure do you create that class to start with?!

Just a related question here:

I have tried both ApplicationEventHandler and IApplicationEventHandler and they are both working fine and same for me.

My question is which one is better to use ?

is working on a reply...
