I'm currently creating the next version of our company's education product, and it seems that we still need to support legacy hardware & software (Win 95/Pentium-1, MacOS 8). To that end, we've been using C++ and wxWindows to minimize the separate code bases between Mac & Windows. However, we've reached the point where we need a total redesign of the source due to previous dogpiling of code onto the already-stretched architecture. Our...

Hi,
I am a Java prof for last 5 years and have delivered many enterprise
application using J2EE. Now my company is making headway in the .NET area of
the market, and I am trying to sort out few issues.

Hello:
I am using ASP.NET as our front end. I also have to interface to some
legacy systems that use a callback mechanism. The legacy systems use
callbacks (via CORBA) to communicate back to clients. The ASP.NET web pages
will initiate communication with the legacy backend, but results from the
backend will often take quite some time and will be asynchronous in nature in
their return. We have successfully created a prototype that...

I have an ActiveX dll written in VB6. It exposes a class called
CustomerDisplays, with a Public Function NewEnum (procedure ID -4,
hide this member), and a Public Function Item (default) and a Public
Function Count. IOW, this thing looks like an enumerable collection
of, in this case, CustomerDisplay objects. Each CustomerDisplay object
has, in turn, an lCustomerID as Long property and a sSortName as
String property. The CustomerDisplays...

I need to keep a few VB6 tcpClients active, but have them talk to a dotNet
tcpServer/tcpListener. The "Server"/Listener is running as a Plugin, and
needs to respond to "outside requests". The dotNet versions of the exe's
that make these requests take MUCH longer to load and start than the VB6
versions, so I'd like to keep the VB6 versions active (at least until the
dotNet versions will load more quickly).
Is there a way for these...

A legacy system is generally any system which is considered pretty old
by software development standards and probably in need of
replacement. It varies a bit depending on where you are. In some
industries a legacy system can be a Corba Application that was made
in the 90's. In my telecommunications background Legacy systems are
much older, often back to 60's 70's, etc.
Often times folks mean big, old, Mainframe applications.

Hi,
I have some legacy ASP web applications that use an unmanaged COM
component to connect to a third party application. The third part
application has moved to the managed code in the current release with
backward compatibility with the unmanaged code.
In the future releases, the vendor is going to drop backward
compatibility and as a result of that all our legacy ASP applications
will break.

I would like to create a .net application that still uses a few screens from
an old legacy application we have.
I can list records from the database in my .net app, but when it comes to
making updates I still need to legacy screens as the update logic is very
complex.
I have found I can use SetParent to "embed" some of the legacy screens
within my .net app, but because they are still basically two separate
applications clicking...

You can effortlessly switch the default language on Windows 10 without reinstalling. I'll walk you through it.

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...

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.

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...
