Hi,
I have 3 questions regarding the code below:
1) Why can't I trap the KEYDOWN while I can trap KEYUP?
2) Is it correct that I use Return True within the IF-Statement? (I've
already read the documentation but it is rather hard to understand so please
don't refer to it :)
3) Many examples in the newsgroups use Return MyBase.ProcessKeyPreview(m) as
the last code line while I have used Return MyBase.ProcessKeyEventArgs(m)

Hi,
I've inherited the XmlDocument class to include some custom methods that I
want to use on a particular XML file.
I need to know whether the document has changed since being loaded, and I
wanted to be clever and hook up to the events that are already defined in
the XmlDocument class (i.e. NodeChanged, NodeInserted).
I had presumed I would simply be able to override them, however I cannot

Hi,
I have such problem:
On my form I have TabControl. I want to move from one tab to another
using "Next" and "Prev" button. This part works fine.
But control also supports switching between TabPagess using
combination of buttons Ctrl+Tab (forward) and Ctrl+Shift+Tab (back). I
would like to suppress such possibility.

Here's a knotty little problem.
I have some nasty little controls that needs to behave in a non-
windows-Standard way - don't ask why; it's a large application being
converted from some older code and my users are adamant
that this behaviour mustn't change.
Specifically, I want to be able to set
myControl.Enabled = False

Hi,
By default, ListView handles Up & Down arrow keys events to change the
current item selected. I need to disable this feature because I do custom
processing on these events.
How can I do that?
Thanks,

When you create a new C# project, Visual Studio creates a main form
for you. If you double click it, the Visual Studio automatically adds
an event handler for the form's Load event. Then you can insert codes
into that method. But, you can also override the form's OnLoad method
and put that code there, which results in the same result.
Since VS.NET does in the first way, it is the recommended way? Is
there any performance differences in...

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

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...
