Sql server express 2005 connections open

Hi All

I have a VB.net 2005 application which uses Sql server express 2005

When I read or write data to sql server I always close the connection immediately after finishing using...
---------------------------------------------------
If Not IsNothing(con) Then

con.Dispose()

con = Nothing

End If

-----------------------------------------------------

When I go into Sql server management studio to detach the database etc there is usually always at least 2 open connections showing in the studio

Close cursor on commit = false

autoclose = false

What am I missing??

Regards

Steve

Hi Steve,

This might be caused by connection pooling. If pooling is enabled, when you
call close() on a connection, the connection to the database is actually
not closed. It was just returned to the pool. This is used to improve
performance if your app is frequently opening and closing connections.

The connections will be closed completely if you close your app. You can
also disable pooling by adding "pooling=false" in your connection string.

If anything is unclear, please feel free to let me know.

Additionally, if you're using VB2005, you can call the
SqlClient.SqlConnection.ClearAllPools() method to clear the connection pool
on demand.
