I am in the process of converting an application to Unicode that is built
with Visual C++ .NET 2003. On application startup in debug mode I get an
exception. The problem appears to be that code with #ifndef _UNICDODE is
executed in output.c, the library code for supporting printf ...

What is the purpose of virtual destructor? If currently, no derived class?

I am trying to wrap some std C++ code so it can be used from C#. The
problem I'm having is that I can't seem to derive a ref class from a C+
+ interface. Compilation fails with C2811: "...can only inherit from a
ref class or interface class". AFAIK an abstract struct constitutes a

I'm in the process of writing a managed wrapper on legacy C++ code.
I have to deal with methods that are using the ellipsis.

Hello, dear guys,
I am a little confused.
My host is 32-bit Windows XP, and my IDE is VS2005 Professional
Edition.

We have an odd situation with some of our single-threaded CPU-bound C++
programs. They run between 2 and 4 times faster on Windows XP than on windows
Server 2003 on the same Xeon hyperthreading dual processor machine (we
borrowed one from our IT department, and have been ...

I have a private static structure in a C++ class (it's a CRITICAL_SECTION
structure) that needs to be initialized by passing its address to a routine
(InitializeCriticalSection).  Since C++ apparently doesn't allow a static
constructor routine, how do I initialize my static ...

I want to modernise, but don't want the lengthy (costly) disruption of
porting my useful stuff to a more recent programming environment.

I am using a DLL function (complied in VC7), which takes a parameter
of 'HANDLE *' datatype.
The DLL developers recommend passing a HANDLE object using the
following syntax:

Why can't I safe_cast a Dictionary to an Object?
Generic::Dictionary<String^, String^> Dict = gcnew
Generic::Dictionary<String^, String^>();
Object^ DictObject = safe_cast<Object ^>(Dict);

I am writing an application in C++ in VS 2005. I wrote a function with
a throw list, but the compiler and the runtime seem to ignore it. tha
function can still throw an exception that does not appear in the
throw list, and the handling environment catches it just fine.

Is there a way to get Visual Studio 2003 look to one directory for
debug version dlls when set to DEBUG and then to another directory
where I store the release version of a dll when set to RELEASE?
My current project uses about 8 dlls I've written in the past, but I
