Hook DirectInput->CreateDevice->GetDeviceData解决方案

已解决，来人散分了，Hook DirectInput->CreateDevice->GetDeviceData
在一款使用DirectInput的3D游戏里面，通过Hook DirectInput8Create函数，CreateDevice方法，取得了GetDeviceData函数指针，在GetDeviceData里面已经可以取得键盘输入的数据（程序未使用GetDeviceState获得数据）

C/C++ code

HRESULT CHook::MyGetDeviceData(LPVOID *ppvOut, DWORD cbObjectData, LPDIDEVICEOBJECTDATA didod, LPDWORD pdwInOut, DWORD dwFlags)
{
    HRESULT hr = CGetDeviceData::Real(ppvOut, cbObjectData, didod, pdwInOut, dwFlags);
    if(SUCCEEDED(hr))
    {
        for(DWORD i = 0; i < *pdwInOut; i++)
        {
            if(didod[i].dwOfs == DIK_CAPSLOCK)
            {
                if(didod[i].dwData & 0x80)
                {
                    m_TurnLeft = !m_TurnLeft;
                    didod[i].dwOfs = m_TurnLeft ? DIK_A : DIK_D;
                }
                else
                    didod[i].dwOfs = m_TurnLeft ? DIK_A : DIK_D;
            }
        }
    }
    return hr;
}

函数是通过定义的基类CGetDeviceData的纯虚函数MyGetDeviceData进入的，现在的问题是：
只有部分键可以修改，例如DIK_I键，打开物品栏，直接写成

C/C++ code

HRESULT CHook::MyGetDeviceData(LPVOID *ppvOut, DWORD cbObjectData, LPDIDEVICEOBJECTDATA didod, LPDWORD pdwInOut, DWORD dwFlags)
{
    HRESULT hr = CGetDeviceData::Real(ppvOut, cbObjectData, didod, pdwInOut, dwFlags);
    if(SUCCEEDED(hr))
    {
        for(DWORD i = 0; i < *pdwInOut; i++)
        {
            if(didod[i].dwOfs == DIK_I)
            {
                didod[i].dwOfs = DIK_L;
            }
        }
    }
    return hr;
}

并不能打开L键的功能，仍然打开I对应的功能（关于这一点不能理解，例如我修改A=D，D=A可以倒转A、D键位），还有我键盘没有SCROLL键，这个键在这个游戏中是录像的功能，我修改HOME键指向SCROLL也没有效果（断点确实修改了）。
在X64 win7系统，不能写驱动实现。

还有如何在MyGetDeviceData添加按键？

附上基类CGetDeviceData代码

C/C++ code

// CGetDeviceData
typedef HRESULT (WINAPI *lpGetDeviceData)(LPVOID *ppvOut, DWORD cbObjectData, LPDIDEVICEOBJECTDATA didod, LPDWORD pdwInOut, DWORD dwFlags);
class CGetDeviceData
{
private:
    static CGetDeviceData* m_this;
    static HRESULT WINAPI _MyGetDeviceData(LPVOID *ppvOut, DWORD cbObjectData, LPDIDEVICEOBJECTDATA didod, LPDWORD pdwInOut, DWORD dwFlags){
        return m_this->MyGetDeviceData(ppvOut, cbObjectData, didod, pdwInOut, dwFlags);
    };
public:
    lpGetDeviceData Real;
    virtual HRESULT MyGetDeviceData(LPVOID *ppvOut, DWORD cbObjectData, LPDIDEVICEOBJECTDATA didod, LPDWORD pdwInOut, DWORD dwFlags) = 0;
    void Init(LPVOID *lplpDirectInputDevice){
        ULONG* vptr = *(*(ULONG***)lplpDirectInputDevice);
        Real = (lpGetDeviceData)vptr[10];
        vptr[10] = (ULONG)_MyGetDeviceData;
    };
    CGetDeviceData(){
        m_this = this;
        Real = NULL;
    };
};
