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!

Tags: VB.Net, ...Cannot overload because they differ only by optional parameters., VS 2005, .Net 3.0

I created a sort of email helper class and I have overloaded my main method SendMsg(...).

I originally created a number of overloads and everything worked fine, but I never allowed a from address as I thought I would be the only one using it and I will put the from address in the config file. I decided to add the from address as an optional parameter to all of my overloads to give that option of passing the from address.

So, It worked before and I was able to overload because each method had a different signature. All I did was add the optional to the end of all of them and they still differ by the parameters that are not optional.

The error says it cannot overload because it differs only by an optional parameter, but that is not true. I have posted the method signatures of a couple of them.

Thanks,
rgn
