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.

How to create an function

Asked by TECH_NET in .NET, Programming for ASP.NET, Microsoft Visual Basic.Net

Tags: ,

I have a sub routine that loop through 10 data points for which i need to plot . for every loop, i the following code is being executed. I am not able to understand how i can create a new GP1 object for each loop.
Sub PlotPolyLine(ID,Latitude ,Longitude,InfoHTML )

'Create points for polyline
Dim GP1 As New GooglePoint()
GP1.ID = ID
GP1.Latitude = Latitude
GP1.Longitude = Longitude
GP1.InfoHTML = InfoHTML
GoogleMapForASPNet1.GoogleMapObject.Points.Add(GP1)
End sun

As you can see in the code snippet the definition of Gp1 and Gp2, Gp3 which are define static and not dynamic. How can i acheive this objective. Where i can retain the googlepoint() handle for each iteration through a loop
something like
for i=1 to 10
PlotPolyLine(ID,Latitude ,Longitude,InfoHTML  )
next i

Thanks. I hope i am making sense. I was told to use object programming..
