Hi,
I have a problem that might be easy to solve(possibly, I've just overlooked
an easy solution). Here we go:
I have a dataset with 2 datatables in it. Now, I need to do the following:
if ds.table(0).rows(0).item("col1") = ds.table(1).rows(0).item("col2") then
txtResult.text = ds.table(1).rows(0).item("col3")

I according to MSDN dataview and dataset are thread safe for read
operations, but we run into this scenario. I just would like to see some
comments on it.
Aplication written in VB.NET it is an ASP.NET app.
located on busy web server.
Initially we defined dataview slightly wrong and run into the problem.
we have dataset cached which has large ammount of data.

Hi, I am hoping I can get some help with a small problem I have run
into using C#. U have an XML file that I load into a Dataset and then
display this in a Datagrid. No problems doing this at all. I then use
a Dataview to filter this view using a keyword and I have no problems
with this either.
What I would like to do is to save this Dataview to a new Dataset so I
can save the reslts to a new file but here is where I am having the...

From that Table in myDataSet I create myDataView and use a Rowfilter to get
a few rows that i work with (i need a DataView cause I do a lot of
filtering)
The problem is the primary key field (a unique counter), let's call it
"TBL_ID".

returned to the calling client application built in windows forms within a
dataset, however upon attempting to create tablestyles to format any of the
columns within the datagrid, the exception "Can-not parent objects created
on one thread to objects created on another" or words to that effect.

Hi, I am looking for a way to sort a strong typed dataset. It would seem the most straightforward way is to use a dataview. The only problem is when I use the dataview I seem to loose the strong typed properties from my original dataset
Anyone that can point me to an example of how to sort my dataset and maintain the use of my typed properties would be greatly appreciated
Thank,
Freeon

I have Dataset that I need to filter into another Dataset for display and I
can not find out how to do this. I have found methods for copying a Dataset
but I can not see how to filter the rows copied using my query.
I hoped to be able to use a DataAdaptor to do this but SelectCommand
requires a connection and I don't see how to create a connection to my
Dataset object.
Any pointers would be much appreciated.
Sid.

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,...
