I have an Access 2000 database with a form that is giving me some
major headaches. When you open the form, it displays all records and
allows editing, but has AllowAdditions set to False so that the user
has to use my New Record button. When you click the New Record
button, the form presents a new record for editing. My client wants
to use the Escape key to cancel changes to new or existing records.
On existing records, Access already...

I'd like to know how can I put up a confirmation question when the
user tries to delete a row in the datagrid by clicking on the row
header and pressing the Delete key?
I have found this code on a windows forms FAQ site :
Public Class DataGrid_Custom
Inherits DataGrid
Private Const WM_KEYDOWN = &H100

Hi
What events are there to do things in when I am on a row in a datagrid
(bound from a dataset) and press Delete key...
There's no Delete Event on the drig and I can't figure out if there are any
events on the Dataset itself either..
I need to delete a row from the database when this happens

I have a datagrid that successfully allows editing and updating (with
dataadapter.update command). I want the user to be able to edit the
"text" in the datagrid, but i DON'T want the user to be able to DELETE
rows.
The OleDbCommandBuilder automatically creates the DELETE SQL statement.
Is there any way I can disable it? If not, what approach should I be
using?
Thanks!

(only thing that should be allowed is left arrow,up arrow, right arrow 39,down arrow,delete and backspace ) when i wrote the following script it works fine in firefox but in IE there is a problem. The problem comes in IE from the fact that the keyboard code and the character code overlap each other, and the character code for the period character is...

I have a combobox with the RowSourceType set to Table/Query and the
RowSource is an SQL query that references a separate lookup table that

limittolist & autoexpand are set to Yes. Control source is set to the
main table field where the data will go.
I can highlight the data that was previously selected in the combobox,
and press the delete key to remove it, but after I move...

Most computers default to English, but sometimes we require a different language, especially when relocating. Forgot to request a specific language before your computer shipped? No problem!

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,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
