Hello,
say, I have a class A which is a subclass of a class B. If we look at the
internal layout of a class A instance than most C++ implementations will
place the members inherited from class B at the beginning and the members
added in the class A declaration behind them, I think. If a pointer to A is
casted to a pointer to B then no action is needed because the beginning of
the A instance is a valid B instance.
But if A is a...

Hi,
I'm looking for a script to get the hi-est z-index on a page.
I want my javascript menu to be always on top of the page (moves along on

Does anyone know how to scann all items/elements on the page for a z-index?
Thanks,

Dear all,
is it possible to determine if a particular control (i.e. Listbox) has
focus, without implementing gotfocus/lostfocus?
I can't find such property.
P.S I know that I can implement such property, with gotfocus/lostfocus, but
may be there is a better way?

Hello.
I am developing an Activex control to show animated gif and other images. With windowlessActivate flag the control is transparent. I want to show animated gif in a thread.
Now the problem:
The thread needs a pointer to the control. "A CWnd*". It works fine without windowlessActivate flag but with the flag I have no CWnd pointer to the control.
Is there a way to get a pointer to the control even though it is windowless?
The control...

I am trying to set the focus on a button that sits on page 1 of my tab control. It looks like I'm successful at setting the focus because I see the highlight on the button, but when I push the space-bar, I get the sub menu for the main form; the button does not press down. I notice that when I click on the tab control, the highlighted button takes on an "added highlight". It looks like a dotted line over the original highlight. If I press the...

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...

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...
