I'm trying to understand SqlConnection(), SqlCommand()
For example. I use SqlConnection() as a parameter when I create a new
SqlCommand. Then I open SqlConnection(), then I execute the SqlCommand().
At that point I cannot use SqlConnection() again. Unless I .Close() it and
then .Open it right?
Then what is 'connection pooling' ?
Can't I run multiple SqlCommand()s on the same SqlConnection() somehow ?

I have a method that gets sqldatareader as shown below.. my question is how
do i close the sqlconnection (objConn) object within this method?
If i put the objconn.Close(); after the return then i get "Unreachable code
detected" and if i close it before the return i get "Invalid attempt to
FieldCount when reader is closed."
When i refresh the page .. lot of sqlconnection is created.. and then i get
this error message :
Timeout expired....

Thanks, Steven

Hi,
In C#.Net, can we have more than one SqlCommand in a SqlConnection?
And in one SqlCommand, can we have more than one SqlDataReader in a
SqlCommand?
In what situation should I use SqlConneciton.Dispose() instead of
SqlConnection.Close()?
Thanks for help.

I normally use SqlConnection, SqlDataReader, SqlCommand for most of my
queries but recently a friend of mine who is a long time java
programmer suggested I use the IDbConnection, IDbCommand interfaces
because the queries where compiled instead of just executed like on
the open SqlConnection. Is he correct and if so does it really make a
difference as far as performance/security, etc?
Thanks for any suggestions

MySQLConnection.connectiontimeout() returns 15. I want to drop that to
3, but it is read only. I see you can include the timeout "Connection
Timeout=30" as part of the connection string but I don't necessarily
want it at 3 during the connection--just for queries. Is there a way to
set it after I'm connected or for it not to affect the connection process?

Hello Everyone,
I'm currently writing a simple Windows Service (C#) that pings an ip address and inserts the pingreply result in a SQL table. I'm able to send a ping request and get the reply status but I have yet to figure out how to get the sql insert to work.
The funny thing is, I'm able to ping and insert through a console application but not a Windows Service. I think it might have something to do with my Account information but my...
