Could anyone please provide a code snippet demonstrating how to use
the Repeater control in conjunction with the PagedDataSource class and
a Strongly Typed Dataset ?
I get an error informing me that my datasource does not implement
ICollection.
All examples of using the PagedDataSource class with the Repeater seem
use untyped datasets.

I am confused how strongly typed dataset is different from un-typed dataset.
Is there any good link explaining pros and cons of both? Which one should be
used preferably?

Hi,
Something I don't understand about a Typed DataSet: When a value in the
DataSet is DBNull, it throws this error: "Cannot get value because it is
DBNull".
But aren't Typed DataSets invented to make life easier, to be able to get to
tge Tables and Values with less code, in less time? But with this thing you
need to add a Try-Catch around every statement when using the value, add for
each value a default value in your DataSet (and...

I've always used untyped datasets. In a Microsoft course, it walks through
creating typed datasets and harps on the benefits. It has you drag all
these things around ..wizard, wizard, wizard... code gen, code gen, code
gen.
What's at the end looks slick, but then there's a ton of generated code that
I'm going to have to maintain now.
I.e. I like typing things myself (don't like wizards) so I can know exactly
what I've done.

Hello
As a known issue, WCF does not allow to transfer typed DataSet. So I have to
copy all data from typed DataSet to untyped DataSet(same table names, column
names and row data). What is the most efficient way to do that? I tried to
remove DataTable from typed one then add to untyped one, but I tell me it is
forbidden to remove tables from typed DataSet.
Thanks

Hi,
I have understood Data Sets but what is meant by typed/untyped/
strongly typed datasets. Can any one explain me or suggest any site/
article, to get these concepts (and their comparisions) cleared?
Thanks,

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

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...
