Errors compiling wincrypt.h

Hi! I have downloaded Microsoft SDK, and this is my code:

Code:

---

#include "stdafx.h"
#define _WIN32_WINNT 0x0400

#include <stdio.h>
#include <windows.h>
#include <wincrypt.h>

---

And when I compile I get these errors:

c:\program files\microsoft sdk\include\wincrypt.h(249) : error C2146: syntax error : missing ';' before identifier 'HCRYPTPROV'
c:\program files\microsoft sdk\include\wincrypt.h(249) : fatal error C1004: unexpected end of file found

Any idea? Thank you in advance.

Have you checked all #include directives are OK?

Hi Doctor :)
I don't know if I need to include some directive more.

The error happens in this line:
typedef ULONG_PTR HCRYPTPROV;

Thank you for your answers.

maybe I have an older wincrypt.h file. I have

typedef unsigned long HCRYPTPROV; and not in the line 249.

Sorry.
