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.

VB.net SQL server connections problem - how to close connection

Asked by CraigLazar in Microsoft Visual Basic.Net, Microsoft Visual C#.Net, SQL Server 2005

Hi,
I a using VB.net 2005 and i have a class in my app which i use to create a sql connection.
So in the rest of my class's/forms ect i create a new reference to my db class call a function and it returns an open SQLConnection.
I have made sure that all the calling functions at the end in my try Catch Finally statement i do th efollowing
            DBConnection.Dispose()  'SqlConnection variable declared Locally to the calling function
            DBConnection = Nothing
            DB_Connect = Nothing 'This is the Class instance name
Now from what i have read, a sqlconnection is an "UnManaged" resource and thats why i need to use the dispose method first.
The problem comes in when i open the SQL Activity Monitor, it shows a whole list of connections to my database and they are in the sleep state.
Then after say 5 minutes they disappear from the list.
So i am unsure of a few things here
1. Am i closing my sql connection objects/refereces from my code correctly
2. Does SQL Server run its own type of "GAC" and removes dormant or sleeping connections after a specific time?
3. By using the dipose and set to nothing commands, should that not immediately close those connections in the Activity Monitor
4. Or is this normal what i am experincing and should not worry?
As i have created a multi threaded service so i need to make sure i clean up correcly

thanks
