Hi,
I need a FAST way to put the content of a file in a datatable (one record
for each line in the file).
I have a routine for it, but it takes me too much time (2-5 seconds for each
file) to put the lines in the datatable and do some actions. Does anybody
knows a faster method? The fact is: I actually only need the lines starting
with "0*" and "1*".

I've got a form with a datagrid that displays a list of items, along
with several textboxes, comboboxes, etc., that display the details for
the selected item. The columns in the datagrid and the "details"
controls are both bound to fields in a dataview called dvItems. The
dataview is a subset of a datatable called dtItems, which is simply a
copy of all the data in a table called Items. The idea is to allow
the user to edit an item in...

I have a program to display queries to a SQL db. I type my query in a
textbox and click a button and the results display in a datagrid. I
could use either dataset or datatable to read the data in then I make
the datagrid.datasource = myds.Tables(0) or mydt. Now what I want is to
be able to change the query and click the button again and get the new
results. I can use clear() to clear the data from a ds/dt but I need
the structure gone...

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...

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,...
