Hi,
I've got a simple console app that just reads an XML file into a DataSet
then prints out a description of each table in the DataSet, including
column names and row values for each column. I'm getting some strange
results depending the input XML file I use. I was wondering if somebody
could help me understand what is going on or point me to a good reference.
The code for my program looks like this:

Hi
I am serializing a dataset using a binary formatter as follows:
IFormatter formater = new BinaryFormatter();
formatter.Serialize(stream, ds); // ds=DataSet, stream=MemoryStream
....
DataSet ds2 = (DataSet)formatter2.Deserialize(stream2);
For the size of my DataSet, its taking 0.8 seconds to serialize and 2.3
seconds to deserialize.

I have a webservice that is returning a dataset. In dataset there is a table
with 4 columns. (LDate, LTime, LDepth and ServiceNumber)
I then try to read only 2 of the columns into array (double
valuesArray;) but i cant get it to work. It is LDepth and ServiceNumber.
Both columns has numbers with decimals. As a newbee i am struggling with
arrays :-)
Best regards
Trond

Hi,
I've been going at this for a few days and can't see the problem. Does
anyone see a problem with this code?
I have a call to a function that returns a dataset and when I assign
values to session variables, the values are the actual column names and
not the database value. I've tried using ordinal values and get the same
results.
--here's the code

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 want to list all of the items in a dataset in a textbox. The dataset
has multiple tables. When I try to use the code below, even though I
dim myState as the DataTable("state"). It still looks for othe rows in
the dataset.
Dim myState As DataTable = myDataSet.Tables("state")
Dim myTax As DataTable = myDataSet.Tables("Tax")
Dim row As DataRow
Dim column As DataColumn

Is there a way, in the debugger, to look at the contents of a dataset? I
tried drilling down into my dataset and it's like exploring the registry!
Anyway, I didn't find anything useful. The code I use to fill the dataset
is below. The dataset fills OK and is usable. I just want to know how it
names things, e.g., if there are multiple instances of a column of the same
name, etc. Right now it can't find Person.Person_ID, although that is...

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

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

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...
