FuncA is called to delete itself with B's help.
In vc 7.0, case 1 seems invalid, but case 2 is valid.
Could anyone explain for me?
class A
{
public:
void FuncA()
{
B b(this);

i'm using a class from some api that is said to automatically call its
destructor when its out of scope and deallocate memory. i create instances
of this class using "new" operator. do i have to explicitly call delete on
these instances when i no longer need them?

This problem shows up in Firefox 1.5.0.1 and Rhino 1.6R2.
I've found that if I have an XML node expression that ends in a filter,
I can't use it with the delete operator. In the following example, the
delete operation has no effect:
var z = <abc><foo a='1'>1</foo><foo a='2'>2</foo></abc>;
alert(z.foo.(@a == '2'));
delete z.foo.(@a == '2');

I have a DataGrid control with a LinkButton command column that deletes the
row. What I want to do is set it up so that there's a client-side Confirm
alert BEFORE the actual Delete command gets called on the server-side. That's
easy to do with normal buttons, etc. as follows...
<asp:Button ID="ConfirmBtn" Text="ConfimMe!"
OnClientClick="if(!confirm('Are you sure?'))return false;"
OnClick="ConfirmBtnClickHandler" Runat="server" />
But...

Hello. The question about "deleting this inside the class's member
function" is discussed many times in this group and in the "C++
FAQs". But I still have two more questions.
1. Take the following class as an example:
class Test
{
public:
static void print_message(char *s) { printf("%s\n", s); }
void delete_me()

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...

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...
