What I want to be able to do:
A textbox is available that the user can enter information into.
Specifically (for the purposes of this post), the user is asked to
enter a number, and that number has an upper limit. I want to do
validation on what the user enters as they type it in.
I set up an event handler for KeyPress that restricts them from being
able to enter non-numeric characters (only allowing numbers, decimal
point, control...

Hi,
I want a rich textbox that dynamically highlights particular words
immediately after they are typed. Just looking for some general
tips...
I tried putting some code in a sub that handles the textchanged event
for that textbox. The issue here is that the focus jumps to the words
to be highlighted (naturally, I suppose, since my technique is to
search for specific words, select them, and highlight them). But I

Hi
How can I send a char to Textbox so that KeyPress event is called? I have a button and with a click I would like to send a char, e.g. "C", to the Textbox. But Textbox1_KeyPress is not catching the event (I can step thru KeyPress ok but nothing goes to TextBox). KeyPress itself works fine with key stroke via keyboard
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Clic

I have a form w/ a textbox and Cancel button on it. I have a routine to
handle textbox.validating, and I have the form setup so the Cancel
button is the Cancel button.
WHen the user clicks on the cancel button, the textbox.validating is
being called. I don't want it to be since they are exiting the screen
the validation doesn't have to be done.
How can I do that.

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'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...
