SharePoint: Writing messages to ULS (Unified Logging System)

7 Comments

• How this differ than logging with Microsoft.Office.Server.Diagnostics.PortalLog ?
  

• Can we really use Microsoft.Office namespace stuff under WSS 3.0?
  

• Hi,
  
  Thanks, works great! If the HttpContext is not null. If it is null, it throwns an exception on this line:
  
  HttpContext.Current.Items.Add("TraceGuid", guid);
  
  Thanks, Ton
  

• Is it a bad idea to register and unregister the trace provider every time you log?
  

• It seemed to cut messages with length > XXX,
  Microsoft itself uses several log entries to store one long message
  

• I don't get why you're doing this big mess just to write to the SharePoint log, when you can just use PortalLog.LogString from Microsoft.Office.Server.Diagnostic
  

• Thanks for question, Cdm. You already answered it too :) SharePoint Services 3.0 has no Microsoft.Office.Server namespace available and if you want to support WSS3.0 and MOSS2007 you should use the code that works on both of them. On SharePoint 2010 you can use new logging stuff that works on services and server both.
