Yesterday I was practicing my rusty C++ and trying to learn DirectX on Windows 8.
One of the (WinRT, C++/CX) sample had a class like that

ref class A
{
private protected:
 int num;
}

Now I'm confused.. what is this 'private protected' thing?
I know protected (only accessible to subclass) or private (accessible to no one else), but what of 'private protected'????

does this compile at all? it does not in my machine.

if it is
private:
protected:

then it make sense.

I have to agree with Mohibur, that doesn't look valid. It's probably a typo (but if it does compile...then it's very interesting because it's the first I've heard of it).

I don't have windows 8 at work but....

I just checked the MSDN sample from (which I did compile and run at home):
http://code.msdn.microsoft.com/windowsapps/Metro-style-DirectX-18f98448

In C++\DirectXBase.h:40 => "protected private:"
And it compiles and run!

Could you provide the actual code?

See here: http://code.msdn.microsoft.com/windowsapps/Direct2D-Image-Effects-2979be08/sourcecode?fileId=44788&pathId=48444729.
If the code is not shown, select Lesson1 - DirectXBase.h on the left side.

I found that code. Its in animate.h file line 40. but the project didnt opened in my machine because of old version(mine). and it is defined as

protected private:

Ho this is a new C++/Cx thing, cool!
Thanks for this complete answer! :)

It was new to me too. But not so new when introduced with VS 2005.
