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! |

Asked by swilson33 in Web Services and WCF, .NET
I need to perform some clean-up operations at the end of my PerSession service. These would normally be initiated by the client in a call to a service operation that is set to IsTerminating=True.
The scenario is this. A user logs into the service and a folder is created on the filesystem of the server. This folder is used to store input files to another application that the service interacts with via COM. The occurence of this folder is also used by my service to determine whether the user is already currently logged on (any particular can is only allowed to be logged on once). So if the session times out or a fault occurs it's important that this folder is removed - otherwise the user can't login to the service again.
How do I perform these clean-ups when a session timeout occurs or the communication channel is faulted? In this cases I need the service to inititate the clean-up since the client can no longer perform these tasks. Is there someway of adding event handlers for these scenarios? I have tried implementing IDisposable but at the session timeout it is not used.
Many thanks
