Hello all,
I'm having some problems understanding all the ins and outs with datasets
and datatables (and navigating through the filled datatable)...
Just when I thought I had gotten the hang of it, another problem arose:
I can't seem to access the "xsi:type" attribute. That is, the XML file looks

I've got a DataTable, see? I'm pulling it from a stored procedure, dig? I've
gotta push it to an array for calculating certain columns, then spit it to a
web page. With me so far? The datacolumns are dates, doubles, strings, man.
How do I store all the different datatypes in a multidimensional array,
dude? Am I looking at a jagged array? Nope, all answers point to another way
of calulating this drek, right? I'm doing this becuase the Stored...

I have a DataRow from a table in a data set. One of the columns has a
name of "COMPANY_TICKET_ID" and I'm trying to get this column's value
with the following:
foreach( DataRow row in ds.Tables.Rows )
Console.WriteLine( row.ToString() );
I get an error - cannot implicity convert type 'string' to 'int'.
What am I missing? Thanks.

Essentially, InsertAT is broken!
For the past couple of hours, I've been getting this "Parameter name:
'-2147483550' is not a valid value for 'index'." error.
Apparently, its caused by having manually inserted a row in the table
bound to the Combo box. The InsertAt Method of adding a row just does
not work.
Hope this helps anyone with this problem.

I'm writing a data conversion application to support a system migration. The code is reading formatted text files and loading them into MS SQL 2005 database tables. I wanted to call the existing INSERT stored procedures in the database to perform the update, yet I don't want to hard-code all the parameter names. Below is a bit of code that reads the imported data from the 'Data' DataTable, and prepares to insert it into the database table...

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

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,...
