We often get connection pooling errors saying that there are no available
connections in the pool.
I think the problem is that we are passing around open readers all over the
place. I am planning on changing this in our code and I expect this to fix
our problem.
We have our connection pooling set to the default number of connections
open. We probably have about 3-7 users concurrently using our web site.
So, the problem isn't that we...

Hello,
I have this code to bind a DataGrid to a DataReader when page loads:
Sub Page_Load(Sender As Object, e As EventArgs)
dgContent.DataSource = drContent
dgContent.DataBind()
End Sub
It's not working.
What is wrong?

Hi,
I'm new to .NET and am using VB .NET as I am from a VB background.
I am having difficulty understanding the way .NET handles, passes and uses
objects.
I have had a look at the Micrsoft Data Access Application blocks for .NET
and am struggling to understand the following:

instantiated inside the function. This datareader is then returned to the

Hi,
In the attached example, I do understand that the references are not changed
if an array is passed by Val. What I do not understand is the result of line
99 (If one can find this by line number) which is the last line of the
following sub routine:
' procedure modifies elements of array and assigns
' new reference (note ByVal)
Sub FirstDouble(ByVal array As Integer())
Dim i As Integer

Hi,
I have a situation where in a dll a SqlDataReader is created on a
function call but is never closed. The datareader gets passed back to
the asp.net page calling it. How should I close the SqldataReader in
the function where it is being created properly? If I close the
SqlDataReader in the function my datareader returns nothing of course.
So how do I code it properly to pass back a datareader and close it in
the function?

I want to create a generic data layer that uses Oracle as the back end. By
generic, I just want a couple of procedures. All access will be done with
stored procs, and I want one that returns a dataset and one that returns a

holds the parameters I want to populate:

Hi, I have just started learning C++ language..
I've read much even tried to understand the way standard says but still
can't get the grasp of that concept.
When parameters are passed/returned by value temporaries are
created?(I'm not touching yet the cases where standard allows
optimizations from the side of implementations to avoid copying)
If so, please quote part of the standard that says that.
Assuming it is true, I can imagine two...

Hey all
I have a vb.net/asp.net dynamic website connected to an access database using a oledb connection. I use a datareader to retrieve the results of a query and iterate through the results using the read() method.
The page in question is a string matching search page (its a photo site and the photos have associated tags) that may return multiple results. I wish to display the first picture match and its details and then have a button that...

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.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

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...
