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.

IIF in where clause of a Linq query

Asked by MadIce in Language Integrated Query - LINQ, Visual Basic Programming

can a case statement or iif statement be used in a linq query? heres what I have as a query.

dim vw1 = from vw in table1 _
where value1 = strvalue1 and (value2 is nothing or value2 = strvalue2) _
select vw.value1
problem is value2 is whatever was selected from a combobox. Sometimes the value should be null. It shouldn't be looking for nothing or what ever value was assigned to strvalue2. problem is if I take out the "value2 is nothing or" part when user selects null I get no records. So I was thinking of using a case statement or IIF statement but not sure if you can in the where clause or what the syntax is. any ideas. using VB 2008
