Question

I currently have Windows SDK 7.0A installed. This version of the SDK contains Xinput.h which references xinput9_1_0.dll:

#define XINPUT_DLL_A  "xinput9_1_0.dll"

I need my program to use xinput1_3.dll instead. I figured that in order to do this, I must link with the xinput.lib file from an earlier version of Windows SDK.

But, which version of the SDK contains the Xinput.h file that references xinput1_3.dll?

Answer 1

I think the solution is actually to use the Microsoft DirectX SDK (June 2010) by modifying the include and library dirs for your project. The XInput.h file from the DirectX SDK…

// XInput.h from the DirectX SDK

#ifndef XINPUT_USE_9_1_0
#define XINPUT_DLL_A  "xinput1_3.dll"
#define XINPUT_DLL_W L"xinput1_3.dll"
#else
#define XINPUT_DLL_A  "xinput9_1_0.dll"
#define XINPUT_DLL_W L"xinput9_1_0.dll"
#endif
#ifdef UNICODE
    #define XINPUT_DLL XINPUT_DLL_W
#else
    #define XINPUT_DLL XINPUT_DLL_A
#endif 

… is actually a little different to the one from the Windows SDK…

// XInput.h from the Windows SDK

#define XINPUT_DLL_A  "xinput9_1_0.dll"
#define XINPUT_DLL_W L"xinput9_1_0.dll"
#ifdef UNICODE
    #define XINPUT_DLL XINPUT_DLL_W
#else
    #define XINPUT_DLL XINPUT_DLL_A
#endif 

So, by default, the DirectX SDK will actually use xinput1_3.dll.
