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! |

Asked by Mr_Fulano in Microsoft Visual Basic.Net, .NET
Hi, I'm using VB 2005, WinForms. I have an application that performs a lot of very complex mathematical calculations. It's running a bit slow, because of how much it has to calculate. I'm trying to tweak my code so that I can make it as efficient as possible. One of the questions that I'm facing is whether to use an "IF Statement" or a "Select Case Statement" in a situation very similar to the one presented below:
If x > 0 AND x < 10 Then
Do this....
If x > 11 AND x < 20 Then
Do this....
If x > 21 AND x < 30 Then
Do this....
If x > 31 AND x < 40 Then
Do this....
etc...all the way to 100.
OR...use
Select Case x
Case x > 0 AND x < 10
Do this....
Case x > 11 AND x < 20
Do this....
Case x > 21 AND x < 30
Do this....
Case x > 31 AND x < 40
Do this....
Case x > 41 AND x < 50
Do this....
etc...to 100.
I would like to use the logic test that is less time consuming, but obviously just as accirate.
Thanks,
Fulano
