I would like to create a component that inherits from sqlconnection, but it
is sealed. What ancestor can I inherit from?
I've seen this:
public sealed class SqlConnection : Component, IDbConnection,
ICloneable
So, I've tried:
public class MyConnection : Component, System.Data.IDb Connection, ICloneable
But I obtain a lot of errors saying:
'MyConnection.M yConnection' does not implement interface member
'System.Data.ID bConnection.xxx xxxxxxxxxxx()'
What can I do?

What can you do? You can learn the language before trying to code
IDbConnection is an interface http://www.google.com/search?hl=en&l...%23+interfaces

General note:
Don't inherit, use composition instead
class MyComponent
{
private SqlConnection connection;
....
public void Open()
{
connection.Open ();
}
public ConnectionState State
{
get {return connection.Stat e;}
set {connection.Sta te = value;}
}
//and so on

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 need to expand the DataSet class by inheriting from it and adding

Hi all,
I have a question/problem concerning usage of my sqlconnection throughout my

In my main form (frmMain) I defined an sqlconnection (I've set the
connection public so that I can open & close the connection from everywhere
in my app).
My main form is an mdi parent which contains several mdi-childs.
To open and close the sqlconnection in an mdi-child i use the following:

Hello,
Here's the scenario:
Object A opens a Sql Db connection to execute number of SqlCommands. Then it
needs to pass this connection to a constructor of object B which in turn
executes more commands on the same connection.
I have an understanding that if SqlConnection is passed as "value"
(unboxed), object B will create its own copy of SqlConnection, so when
object A closes its connection, it remains open for object B's copy. Is this

I have an SqlConnection object within my Web.UI.Page object. The
thinking is that the connection to the database server is opened once
when the page starts to do its thing, then when everything is rendered
down to the browser, and all references to the page object are ended,
the connection to the server can be closed.
First of all, are the SqlConnection Open and Close methods quick

Hi Guys I have a problem here.
I want to improve the performance for a website. When I looked into the
system, I have found that the system made the "SqlConnection Object" static.
That mean only one SqlConnection object will be used.
Can someone tell me is that a correct way to do? Does that affect the system
performance?
Cheers

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.
