I’m sure I’m not the first person to come up with this. Međutim, I haven’t noticed anyone publish a trick like this since I started paying close attention to the community last July. Tako, Mislio sam da bih objaviti ga to brzo i lako ispravljanje savjet.

I’m working on an event receiver that started to generate this error in the 12 košnica:

Pogreška pri učitavanju i trčanje događaj prijemnik Conchango.xyzzyEventReceiver u xyzzy, Verzija = 1.0.0.0, Kultura = neutralni, PublicKeyToken=blahbalhbalh. Additional information is below. : Objekta nije postavljena na instancu objekta.

I didn’t know where I had introduced this bug because I had done too many things in one of my code/deploy/test cycles.

I tried this solution to get my pdb in there with hopes that SharePoint’s 12 hive would show the stack trace, but no luck. I don’t know if it’s possible and if someone does, javite mi 🙂

I know it’s possible to write your own log messages to the 12 košnica. Frankly, I wanted something a little less scary and quicker to implement.

It occurred to me that I could at least get some basic trace information by catching and re-throwing generic exceptions like this:

  pokušati {
    UpdateEditionDate(Svojstva);
  }
  ulov (Izuzetak e)
  {
    baciti novi Izuzetak("Dispatcher, UpdateEditionDate(): Izuzetak: [" + e.ToString() + "].");
  }

This showed up in the 12 hive thusly:

Pogreška pri učitavanju i trčanje događaj prijemnik Conchango.xyzzyEventReceiver u xyzzy, Verzija = 1.0.0.0, Kultura = neutralni, PublicKeyToken=blahblahblah. Additional information is below. : Dispečer, UpdateEditionDate(): Izuzetak: [System.NullReferenceException: Objekta nije postavljena na instancu objekta. at Conchango.xyzzyManagementEventReceiver.UpdateEditionDate(SPItemEventProperties svojstva) at Conchango.xyzzyManagementEventReceiver.Dispatcher(SPItemEventProperties svojstva, String eventDescription)].

That gave me all the detail I needed to track down that particular problem and I expect to use it a lot going forward.
