All of my web applications manage their sessionthrough SQL Server and an assembly I built that I published inthe GAC. It's a service component and runs as a ServerApplication in Component Services under a particular identityinstead of the identity of the application that is calling it. I use the object...

We're getting an occasional occurrence of the following error when two users
try and open the same record in our ASP.NET app:
"There is already an open DataReader associated with this Connection which
must be closed first."
As suggested, I was closing the connection in the Finally part of the outer
Try but I wasn't closing the data reader as well so I assume that if the

Hi,
I am getting issues that Oracle collecting opened sessions (connections)
from my webservice using regular System.Data.OleDb.OleDbConnection object.
I am guessing that this is connection pooling issue. Is there is any way to
disable connection pooling for one particular .net webservice?
Thanks,
Leonid

Hi ,
I am using OracleConnection object from Oracle ODP.net provider and
following is the behaviour which i am finding bit strange :
To start with my argument is based on followings facts :
1. Connection object is a reference type object .
2. All reference types are passed by reference even when done without
using modifier like ref / out .

Hallo!
I'm working with C# .NET 2.0, implementing Client/Server Applications which
are connecting via Network to SQL-Server or Oracle Databases.
To stay independent from the underlaying Database I use
System.Data.Common.DBConnection and .DBCommand.
How can I keep aware from connection losses (network not availeable,
db-server not available...)?
Are there any strategies to detect this broken connections, and how can I

Hi,
In an existing ASP/ASP.NET 1.1 app running on IIS 6, I need to RELIABLY
pass the logged in username through to the SQL Server 2000 database for
auditing purposes. The current method is hideously unreliable. The app
includes updategrams, XML Templates and ADO connections.
I don't want to use impersonation because of the direct db access that
allows.

Hello All,
Some time ago, I implemented a data access layer that included a simple
connectin pool. At the time, I did it all by myself: I created N
connections, each connection associated with a worker thread that would
execute the db commands. The pool was fixed and all the connections
were created when the db access class was instantiated. The
connections remained opened during the whole execution. If a connection
was not available...

I am using VS2003 and connecting to MS Access database.
When using a connection pooling (every time I open the OLEDBCONNECTION I use
the exact matching connection string),
1. how can I know how many connection has been used ?
2. If the maximum pool size has been reached, what happens when I call the
method Open to open the connection ? Will I get an error ? MSDN says the
request is queued, but will I get an error in the open method ?

In the Windows application (using VB.NET 2005) I use connection pooling like
the following:
In the main form load I open a connection using a connection string that I
stored in a global variable g_sConnectionString and leave this connection
open and not close it until it exits the application.
Then on each thread/each subsequent sub that needs the connection I create a
local OleDBConnection variable, open the connection using the exact...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
