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!

Casting Difficulties

Asked by si2030 in Language Integrated Query - LINQ, Microsoft Visual Basic.Net

Tags: VB.NET LINQ

Hi Experts,

I have a LINQ expression that produces a single decimal number - 4201.00D.

The problem is, I cannot get this to be accepted into the textbox I have.

While the LINQ statement looks a little complicated (see below) it works and it delivers the number above. I cannot get my textbox to accept this number.

The error  I get is:

Conversion from type 'DataQuery(Of Decimal)' to type 'String' is not valid.

I have tried Ctype and trycast (trycast just gave me nothing).

So, my question is, how to you cast succesfully to allow a textbox to accept your LINQ statement result.

Kind Regards

Simon
