Hy
I have destructors that do some functional work in the program flow.
The problem is destructors should only be used for clean-up, because
exceptions might rise at any time, and destructors will be called for
clean-up only.
So how can I tell, from within the destructor, if the call has been made as
part of normal flow of control and the destructor can play its functional
role, or if the call has been made as a result of an...

Hi All,
I'm in the middle of porting code to VS.NET from VS6.0. My code compiles
fine under DEBUG mode but under RELEASE mode I get a compile-time error:

: is not a member of 'CWinApp'

Hi,
I have an application which was developed with Visual C++ 6.0 and MFC.
In the application, the CWinApp::WinHelp method was overridden to
support context sensitive help (F1 help). The application was recently
upgraded to Visual Studio .Net 2003. The help links no longer work.
The WinHelp method in my derived application class no longer gets
called, when the user presses F1 in the application as before. The
application instead looks...

I have created an MFC project that links MFC MFC as shared dll and uses
/MD . This MFC application loads another dll B via Loadlibrary that
has /MD too and also links MFC as shared dll. Dll B again loads dll C
that also uses MFC as a shared DLL dll and also has /MD.
Also the MFC app statically links to a .lib that has MFC linked as
shared dll and has /MD
Now for some odd reason when the constructor of my MFC app is called...

According to MSDN2, if a managed class throws an exception in the
constructor, the destructor will be called. If an exception is thrown in the
constructor the object never existed so how in the world can the destructor
of a object that does not exist get called!
Here is the MSDN2 document:
Code authored in Visual C++ and compiled with /clr will run a type's
destructor for the following reasons:

Hi,
I'm currently working on integrating our company's management system into .NET. The system was originally created in Visual C++ 6.0, but new requirements point to that we may need to make use of .NET Web Services. I've already succeeded in getting all our system code to compile into a new C++ web service.
The problem is that I need to "start" a the system from within the Web Service (I'm currently implementing this code in the...

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

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...

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...
