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!

Best strategy for incorporating LINQ into a Windows Form Application

Asked by bryan_z in Language Integrated Query - LINQ, C# Programming Language, Visual Studio

Tags: C#, LINQ, .NET Forms, VS 2008

I'm playing around with LINQ for a few future projects and was curious, design wise, what people feel is the best approach to handling LINQ in a windows form application regarding:

1) Determining if an object is new or just needs to be updated.
2) What needs to be declared as instance-level variables in the form class

For example, if I have a Data Context dc and a LINQ Object Person,

1) What is the best mechanism to determine if this object already exists in the dc or if it needs to be created.

2) Is there a way to update only the fields that changed? Know what changed?

3) Do I just hold onto the data-context or do I need more?

What approaches are others using?
