I'm trying to detect if there are any unsaved changes in a
dataset when a user hits close form button (top right hand
corner).
My problem is that HasChanges does not detect a row that
has been modified if the cursor has not "left" that row
after modification. So if I edit a cell in a row of the
datagrid and then immediately click on close form, the
dataset has no changes, yet it really should.

Hi, in the NorthWind sample database, when clicking on the next
navigation button on the new order record with nothing on the subform
(order details), we got an order with nothing ordered. How can we
prevent this from happening?
Thanks.

The issue: I have a grid which has a dataset as the datasource.
If a user enters data in a textbox on the grid and then clicks on the close
button of the form (the red X in the upper right corner), no events fire for
the grid or the control that the user was typing in.
The closing event of the form does fire, and I check there to see if any
changes need to be saved. If the user changes rows in the form, the typed
data is transmitted...

Hi, I have a window based program. One of the form has several textboxes and
a datagrid. The textboxes are bind to the same dataset table as the datagrid
and the text changes to reflect different row selected in the datagrid.
I want to save the changes that user make in the textboxes when they select
a different row in the datagrid. I tried capturing the textbox.text at
datagrid's CurrentCellChanged event but by then the textbox.text...

Hi,
I really hope someone can help me out here.
In relation to this thread ( http://www.thescripts.com/forum/thread349557.html ) I'm having a similar issue and getting nowhere fast!
In a nutshell I have a MDI Container which can load up several forms.
Upon loading of a form, I want this form to either access or load a dataset and populate controls that have been bound to various fields of the dataset.

Hi all,
Using C# 1.1

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,...

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.
