Hi Everyone.
I have been designing a form with about 100 or so controls and today I
pasted some code from another test project into this one and then all the
controls on the form disapeared from view. If I look at the
Region " Windows Form Designer generated code" section I can see the code
for the controls are there. Except for a few controls, like a tab control and
some labels (these controls are highlighted with errors). Why would this...

Hi all,
Is the above possible?
I guess I need an API call for this ? How and where to find this?
One of my new apps is used as a sort of 'dedicated' thing.
Users see an empty desktop with *only* two buttons. They only click a button to start the app.
(They have two apps they need to work with)
When they minimise the app (and some do this accidently...) the app is NOT visible anymore in a taskbar or so.
In fact there is NO taskbar... ...

Hello,
I am looking for a clever way to prevent someone from pasting copied text
outside of my app.
I know how to monitor the clipboard and get an WM_DRAWCLIPBOARD message when
text is stored in the clipboard... If only I could detect some kind of
outgoing message that the clipboard is about to paste, then I could check to
see if my app is currently in focus and allow/deny as necessary.

Hi all,
I have a form where we would like the user to input their email address
twice, to ensure they've typed it correctly, as is found on most
sign-ups
I'm looking for a solution to the problem where a user (and me it has
to be said) just either highlights the email address with their mouse
(or Ctrl-A) and then Ctrl-C, Ctrl-P (or right-click copy, right-click
paste) into the next field down.

Hi,
I'm developing an application with VB.NET 2003 and I want to forbid
pasting into a textbox.
The problem is not the context menu, but the Ctrl+V shortcut.
How can I prevent that the user can paste anything into a textbox, even
if (maybe) another shortcut for Pasting has been defined?
Thanks in advance!

Hi,
Currently we have a text box which takes only Numbers. but using control keys and mouse we are able to paste string which has invalid data (i.e. !!@nmbdnm). So how can I restrict the pasting of invalid data on the text box while it should allow numeric strting to be pasted.

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....
Now, this would greatly impact the work of software developers. The idea...

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...
