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!

A Crystal Report in an upgraded vb.net 2008 project comes up blank

Asked by accucom in Crystal Reports Software, Microsoft Visual Basic.Net, Visual Studio

Tags: vb.net 2008, Crystal Reports, Visual Studio 2008

I am trying to upgrade a vb.net project from 2003 over to 2008 and most everything seems to work fine, but when I go to a section where it displays a Crystal Report within a frame, it at least shows the header, footer, and any fixed text, but does not seem to show from the fields used from my query from an Access Database.  All this worked in vb.net 2003 but is behaving differently in 2008.  I tried installing updates and still the same thing happened.  Please advise as I am including a snippet of the code involved when I press a button to generate the report.
