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!

Inheritence - Create derived class from base class...options???

Asked by pbfonline in Software/Systems Design, Miscellaneous Programming, .NET

Assume I have Class Animal. And Class Monkey, which is Derived from Animal.

If I have a Class Animal, is there any way to "convert" it to Monkey without copying over all of the properties?

Animal is the Base Class of Monkey, so I'm hoping there's a way to convert (or actually "redim preserve") the base object and just add in the additional properties, methods, etc to make it a Monkey, but I can't figure it out.

Can you Redim Preserve myAnimal as Monkey?
Can you pass Animal into the Constructor of Monkey and use it as the base class?

Animal is already instantiated. I just want to use it as the base class for a New Monkey.

Can you do this in VB.Net?
