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!

Don't undestand interfaces concepts...

Asked by jaja2005 in Delphi Programming, Miscellaneous Programming, Delphi Components

Hi All.
I am trying to undestand what are the advantages of using interface in delphi.
I have already learned the basical things like how creating a new class that
implements one or more interface. I found a good explanation made by bladrick
user who wrote that an interfaces allows to set a CAN_DO relationship so
someone can iterate on objects of different classes and checks (using Supports and
Queryinterfaces methods) if they implements a specific interface. If so
I can call the procedure like ImyInterface.DoSome;

By the way apart this point i still have some doubts on this topic. Why I should
use them it's not completly clear to me. I would appreciate to get
suggestions and more examples so that I could say, well..this is great, if i
learned interface before i could do this and that....writing better code.

thx
