GetAncestor: Undeclared identifier

Question

I'm using Visual Studio 6 for backward compatibility reasons and I need to use GetAncestor() like this to create a dll :

HWND ancestorhandle = GetAncestor(myvar, 2);

I've included these header files:

#include <windows.h>
#include "stdafx.h"
#include "offlinelib.h"
#include <stdio.h>

As per the documentation:

But while compiling, I get an error:

GetAncestor: Undeclared identifier

What am I doing wrong?

If you are using precompiled headers `stdafx.h` **must** be the first `#include`. — Captain Obvlious, Jul 17 '15 at 17:56

Try moving the #include "stdafx.h" (precompiled header) up, making it the first include line.

I still get the same error after your suggested change: See here for the complete code http://pastebin.com/UA931nJu – user994572 Jul 17 '15 at 18:49

Solved by adding

#ifdef WINVER
#undef WINVER
#endif
#define WINVER 0x500

on top of stdafx.h

It would be better to set the `WINVER` value in your project settings instead of in your code. But in any case `WINVER` should already be set to `0x500` (win2K) by default, so something else in your project is setting it to a lower value or `#undef`ing it, so you should find that something and remove that instead. – Remy Lebeau Jul 18 '15 at 00:30
You should delete the question. It's pointless. This answer shows why. It's only relevant to code that only you can see. – David Heffernan Jul 18 '15 at 04:32
