The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Mysterious Exception

Asked by Nugs in C# Programming Language, Programming for ASP.NET, .NET Framework 2.x

Tags: C#

Hey guys,

This one is a shot in the dark cause i am not sure what the issue is here, i am hoping that someone can enlighten me maybe.

I do extensive error logging and reporting on my website. Since i went live a couple of weeks ago i have encountered a number of exceptions (that were logged and reported to me by my code) of which i have resolved most. None of which, including the one i am about to mention i was ever able to reproduce in development.

My site also tracks user sessions. And i have built and entire back end system that allows me to tie a particular exception to a session. This one does not have a session relating to it... Weird, i would have thought that a user would trigger exception errors but it appears not to be the case.

ERROR MESSAGE:
----------------------
Object reference not set to an instance of an object.

STACKTRACE
------------------
   at ASP.global_asax.Session_Start(Object sender, EventArgs e)
   at System.Web.SessionState.SessionStateModule.RaiseOnStart(EventArgs e)
   at System.Web.SessionState.SessionStateModule.CompleteAcquireState()
   at System.Web.SessionState.SessionStateModule.BeginAcquireState(Object source, EventArgs e, AsyncCallback cb, Object extraData)
   at System.Web.HttpApplication.AsyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

EXTRA DATA

System.Collections.ListDictionaryInternal

SOURCE

App_global.asax

TARGETSITE

I get at least one of these every day! Does anyone maybe know what is going on?
