Hello
I'm wondering if anyone out there might give some
input/suggestions/viewpoints around the Command pattern.
In my case, the number one priority for using the pattern is undo support.
Some now, a lot more in the future.
I think I have a pretty good understanding about how the command pattern is
tought to work, however during implementation I'm htting a couple of quite
large design considerations that I'm not sure I have the answare...

Hi. I'm writing a command shell that reads commands from standard input.
At this point I have the command in a std::string. Now I want to execute
this command in the shell. From the Borland newsgroups I learned that there
is a function in stdlib.h called system.
int system(const char *command);
First question, is the system command ANSI compliant. Because I include
<cstdlib> and write std::system(command.c_str()); it looks like an...

I'm a teacher using MS Access on an RMConnect 2.4 network. On some
workstations both I and my students sometimes get an error message
when attempting to insert a command button on a form which reads
"Invalid
use of null". The remainder of the options in the Command Button
Wizard are then unavailable and
the button wil not work.
The only solution is to log on to a different workstation.
Any ideas?

I am implementing the command pattern in VB.NET, where the commands have
been serialised. That is, I have several classes that all inherit from my
base Command class, that implements ICommand (standard stuff). The commands,
however, are deserialised at runtime, so the idea of passing a receiver in
the constructor does not work in this case.
In addition, I am implementing the MacroCommand extension, and each command
in a macro could...

I have been trying for days to send a command to the command prompt
through the shell() function in vb.net. For some reason it is not
working. Here is the code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click
Dim command As String

New on November 29, 2005 for www.FluffyCat.com PHP 5 Design Pattern
Examples - the Command Pattern.
Since you all enjoyed the Visitor Pattern so much yesterday, today I
have the Command Pattern for you. This one is pretty straight
forward. In the Command Pattern an object encapsulates everything
needed to execute a method in another object.

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...
