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.

Nested Classes, Variable Scope, and method scope.

Asked by The_Computer_Guru_777 in Microsoft Visual Basic.Net, Miscellaneous Programming, .NET

Tags: vb.net, classes, scope, nested, vs 2005, .net 2.0

I am having trouble with nested classes. I am new to classes in general, but have been using VB for a while.

I don't won't to create more instances of the nested classes to call them, but I don't want them to be "shared" either. I also want the outer classes variables to be readonly when inside a nested class.

If I make the functions of the nested classes shared, then I can only use other shared functions inside the functions. Which I don't want.

If I use an instance of the nested class to call one of it's functions, then I don't have the parent classes variables anymore, because I would be inside a new instance.

What are the best practices with nested classes (MSDN didn't help me much) ?

How should I implement this type of program (see code below) ?

How Do I make outer class functions not appear under inner classes?

Any help I can get would be great.

The code below is what I want, but currently won't work unless I make version4 and version5's functions shared.
