We have an object factory that returns weakly typed
datasets (just plain ol' DataSet's). I need to cast it, or
transform it, or map it to a strongly typed dataset.
There's an old adage I heard from a Microsoft developer a
long time ago: If it's taking more than 10 lines of code,
then you are doing it wrong.
Is there an *easy* way to do this in a *generic* way? I
have been experimenting with serveral techniques and

Hello.
I am getting an InvalidCastException which has revealed yet more of my ignorance. I cant believe i
dont already know this and haven't encountered it before until now.
I am consuming a dataset from a webservice. I wrote both the server and client apps and the both use
the same middle teir. I fill a dataset on the server that has a relationship between two of the
tables inside. The relationship is between two strongly typed tables...

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?

I have been developing applications with Java for quite a while but I am new
to .NET development. I am trying to learn the ".NET way" of creating Strongly
Typed Objects from a database. The Enterprise Library seems pretty close to
what I am used to in Java but I am not sure how to create strongly-typed
DataSets. I see that I can use the LoadDataSet method from a
Microsoft.Practices.EnterpriseLibrary.Data.Database but I am not clear on how...

Hi!
How do I explore in code, which properties (columns) are in a datatable? I
need to run some code for each column.
I guess the answer is reflection somehow, but I dont know where to start.
If someone could point me to a relevant example, I would be most grateful.
:)

I'm writing an winforms app in vb.net 1.1 and am having trouble referencing
a strongly typed dataset in the UI project. The dataset's source is behind
a web service and the data project (client side) gets a reference to the
dataset schema and all that comes with strongly typing a dataset via a
reference to the web service. The business tier which depends on the data
tier and also imports the namespace of the data project can reference...

Hello
I developed and tested a web application using VS.NET 2003, VB, .NET
Framework 1.1.4322, ASP.NET 1.1.4322 and IIS5.1. It uses a web form.
I used the XML Designer to create an XML .XSD Schema to produce a Dataset.
In looking for a way to start adding data to the dataset programmatically, i
found this method in just about every thing i read.

I'm a bit puzzled by the current recommendation not to send Datasets or
Datatables between application tiers.

Formerly, with classic Microsoft DNA architecture, the ADO Recordset was a
primary transport medium, recommended for transmitting data between
application tiers. In fact, there are whole books written on the subject.

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...

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...
