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!

Why does this code not compile on Delphi 2010 (compiles on Delphi 2009)?

Asked by FALECoder in Delphi Programming, Delphi Curiosities, Delphi IDE

Tags: Delphi 2010, Delphi 2009, compile, error

Hi!
I've been using Delphi 2009 and am now testing Delphi 2010. When trying to compile a project, for some reason I get a "Missing operator or semicolon" error in the file attached, and can't understand why this happens. It compiles fine on Delphi 2009 and I thought there shouldn't really be many code changes between 2009 and 2010 (still remembering with a shudder the migration process from Delphi 7 to Delphi 2009 with the Unicodes and was hoping this to be smooth...). The entire problematic unit is attached below (error comes on line 266) and to reproduce the problem no other units seem to be needed. Screenshot of error is also attached. Any help would be appreciated - is this something caused by Delphi 2010 or am I missing something obvious?

Thanks!
