I have a problem with a datagridboolcolumn that drives me almost
crazy.

column called ok which is a bit with default value 0. In a datagrid
that shows several columns of the table (with datagridtextboxcolumns)
I also included a datagridboolcolumn with true-value 'true' and
false-value 'false' and allownull=false. I had the sqldataadapter made

Hi,
In the past I've successfully databound a conventional Winforms checkbox to
a number column in an Oracle table, where 1 represents true and 0 represents
false. The checkbox would be ticked if the value was 1 and unticked if the
value was 0 - earth shattering news I know! :-)
HOWEVER......
I tried doing the same thing but in a datagrid with one of the columns as a

OK - I'm looking for the best approach on how to do this.
I have a form page where the user can edit their "Profile" (data) which is
in SQL Server. It's your basic company information - address, phone
numbers, etc. I also have on the form a CheckListBox which is bound to
another table in SQL Server - let's assume it the USA States so there's 50
checkboxes dynamically written to the page. When the user "adds" their
data, they check all...

I'm trying to create a custom DataGridBoolColumn. I inherit
DataGridColumnStyle and create a public CheckBox variable. This columnType
will be mapped to a dataTable boolean column. What are the basics of the
Draw and Edit methods that I need to implement in order to see the checkbox
in the cell?
I have tried the following, but it hasn't worked. (CB is the public
checkbox):

I have a DataGrid on a form in my application that is bound to an xml file
and I have set the table style to contain a few columns with one editable
one, a DataGridBoolColumn.
I set DataGrid.ReadOnly to True and the DataGridBoolColumn.ReadOnly to false
but I still cannot access the check box. When I click on the box nothing
happens.
If I set DataGrid.ReadOnly to True then I get the option to add a new line
on the grid, which I don't...

i have a DataGrid with a DataGridBoolColumn. The assigned Column is a

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,...

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...
