At least they are honests
(It is at the top of the code snippet):
Anyway, it is also stated:
placement
Provides a way of passing additional arguments if you overload new.
hence you probably have to overload the operator to use additional placement argument.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Yes I have seen it.
If it gets a C2660, there wouldn't be a successful build and no chance to execute the call.

In the comment, it specifies the global operator new . I guess MSDN didn't intend to ask user implement an operator overload.
Anyway, it's fun to see a junk sample in MSDN.

If the placement usage is for overloading, then overload is probably needed.

If I remember rightly this is implemented in the STL so you need to include the right STL header to make this work #include <memory>
Nothing is exactly what it seems but everything with seems can be unpicked.

Have you tried #include< new > ?

Not working either.

Hmm, I think I remember the example you're talking about and I remember struggling with it but I don't remember how to fix it, sorry.

No doubt the article is poorly written. If you follow the links and read the grammer for the placement operator new you should come up with the following for the sample class (see following note below):
class A {
public:
A(int) { throw "Fail!"; }
void *operator new(size_t stAllocateBlock);
void *operator new(size_t stAllocateBlock, char chInit);
void *operator new(size_t stAllocateBlock, char*, int);
};
void *A::operator new(size_t stAllocateBlock)
{
void *pvTemp = ::malloc( stAllocateBlock );
return pvTemp;
}
void * A::operator new(size_t stAllocateBlock, char*, int)
{
void *pvTemp = ::malloc( stAllocateBlock );
return pvTemp;
}
void * A::operator new(size_t stAllocateBlock, char chInit)
{
void *pvTemp = ::malloc( stAllocateBlock );
if( pvTemp != 0 )
memset( pvTemp, chInit, stAllocateBlock );
return pvTemp;
}
If you compile this you will get the warning (C4291) that the article is trying to highlight. If you provide a placement new operator for a class you need to provide a matching delete operator.

I have created a Resource-only Dll viz. Language, which includes only resources i.e
Dialogs,
Toolbars,
Acceleraters,
Bitmaps,
Icons,
String Tables,
Version etc.
I have created one Dialog Based Application viz. LanguageApp, which includes only code - nothing else.
Now, I want to load each-n-every resource from the dll Language to application LanguageApp without including resource.h file of the dll.

Use the APIs FindResource and LoadResource .

Hence you cannot add resources to the DLL!

Hi all,
I want to add two radio buttons to select two states, + or - option. How can I do that.
I've try this, add to radio buttons and add member variables to them as well. Then I want to get the user selected state from there and do my processing. But I've no luck to find it.
I appreciate your help all the time...

Are you talking about the GetCheck() and SetCheck() methods?

Add this on the topmost line in .cpp files.
#include "stdafx.h"

Where is the project from? You created it? Or you got from someone else?
If the project is created by yourself, either project type MFC or Win32 generates an "stdafx.h " file automatically in the project folder, unless you were starting from an empty project.
