C++ StringCchPrintf identifier not found

So, I am fairly new to C++ and I am trying to get a list of files in a directory. I found a solution from microsoft here:

https://msdn.microsoft.com/en-us/library/windows/desktop/aa365200(v=vs.85).aspx[^]

but when I go to build it I get an error:

error C3861: 'StringCchPrintf': identifier not found

The error is from this section of the code:

C++

StringCchPrintf((LPTSTR)lpDisplayBuf,
    LocalSize(lpDisplayBuf) / sizeof(TCHAR),
    TEXT("%s failed with error %d: %s"),
    lpszFunction, dw, lpMsgBuf);
MessageBox(NULL, (LPCTSTR)lpDisplayBuf, TEXT("Error"), MB_OK);

StringCchPrintf is in

C++

<strsafe.h>

and I have searched strsafe.h, but I dont know what the problem is. It appears to be defined.

If anyone could help me with this that would be great.

Thanks,
Mitch

Are you sure you #included strsafe.h correctly?

Strange. Is your system supported? Have you a modern compiler?
I've just compiled the example found in StringCchPrintf documentation, namely

XML

#include <Windows.h>
#include <strsafe.h>

int main()
{
   TCHAR pszDest[30];
   size_t cchDest = 30;

   LPCTSTR pszFormat = TEXT("%s %d + %d = %d.");
   TCHAR* pszTxt = TEXT("The answer is");

   HRESULT hr = StringCchPrintf(pszDest, cchDest, pszFormat, pszTxt, 1, 2, 3);
}

without problems on my Windows 8, 64 bit system, using Visual Studio 2012.
