Hi all.

I tried to follow this documentation on how to register custom events https://our.umbraco.org/wiki/reference/api-cheatsheet/using-iapplicationeventhandler-to-register-events

But i cant figure how to hook into the Media event.

This is what ive got so far. Any pointers would be appreciated.

using System;
using umbraco.cms.businesslogic;
using umbraco.cms.businesslogic.media;
using Umbraco.Core;

namespace hook.event.test
{
    public class HookIntoMedia : IApplicationEventHandler
    {
        private static readonly object LockObj = new object();
        private static bool _ran = false;

        public void OnApplicationInitialized(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
        {
            if (!_ran)
            {
                lock (LockObj)
                {
                    if (!_ran)
                    {
                        // What do i pass into Media_BeforeSave(?,?) and  Media_New(?,?)
                        Media.BeforeSave += new Media.SaveEventHandler(Media_BeforeSave);
                        Media.New() += new Media.NewEventHandler(Media_New);
                        _ran = true;
                    }
                }
            }       
        }

        private void Media_BeforeSave(Media sender, PublishEventArgs e)
        {
            // Here i wanna do some crazy stuff.
            e.Cancel = true;
        }

        private void Media_New(Media sender, PublishEventArgs e)
        {
            // Here i wanna do some crazy stuff.
            e.Cancel = true;
        }

        public void OnApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
        {
            throw new NotImplementedException();
        }

        public void OnApplicationStarting(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
        {
            throw new NotImplementedException();
        }
    }
}
