I use AfxGetApp() in my Add-in application as follows.
AfxGetApp()->LoadIcon(IDI_ICON);
AfxGetApp()->BeginWaitCursor();
AfxGetApp()->EndWaitCursor();
AfxGetApp()->PumpMessage()
It works well in Vc 6.0. However, AfxGetApp() returns NULL after I convert
my project to Vc.NET.

Hi everyone
I'm having huge difficulties overriding a virtual function with a function
that returns a covariant type. I'd be grateful if someone could show me some
code where this is done:
- A class BaseClass is declared with a function me() that takes no arguments
and returns itself, or a pointer or reference to itself.
- A derived class DerivedClass that override me() that takes no arguments
and returns itself, a pointer or reference...

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:
C:\Program Files\Microsoft Visual Studio .NET
2003\Vc7\atlmfc\include\afxwin2.inl(1034) : error C2039: 'Enable3dControls'
: is not a member of 'CWinApp'
C:\Program Files\Microsoft Visual Studio .NET

I have a .Net Managed C++ wrapper control for a MFC control. When using the
..Net control in a Visual Studio 2005 Beta 2 C# project and running in Debug
mode, I get a crash saying something like "First Chance Exception : memory
cannot be read". I found that this was becuase a call to AfxGetThread() was
returning NULL. I tried using AFX_MANAGE_STATE(AfxGetStaticModuleState());
but it did not solve the problem.
Furthermore, this crash only...

Hi,
I have a huge VC6 MFC project that was converted to Visual Studio 2005
beta2. After the conversion, the application crashes because
AfxGetThread() returns NULL and thus fail on pThread->InitInstance()
inside AfxWinMain().
I have a CWinApp derived class (e.g. CBaseWinApp) exported from a DLL.
This derived class is inherited inside the main app (e.g.
CDerivedWinApp : public CBaseApp) and serves as the global app.

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...

Is it possible to return covariant types for virtual methods inherited
from a base class using virtual inheritance?
I've constructed an example below, which has the following structure:
Shape = base class
Triangle, Square = classes derived from Shape
Prism = class derived from Shape
TriangularPrism, SquarePrism = classes derived from Triangle and
Prism, or Square and Prism respectively

Hi,
I'm currently working on integrating our company's management system into .NET.

The problem is that I need to "start" a the system from within the Web Service (I'm currently implementing this code in 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...

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,...
