如何dinput.dll中导出DirectInputCreateEx函数

[ustcsongyudong]

我欲从dinput.dll中导出DirectInputCreateEx函数

HANDLE handle=LoadLibrary("c:\\windows\\system\\dinput.dll");
HRESULT (* myDirectInputCreate)(HINSTANCE,DWORD,REFIID,LPVOID*,LPUNKNOWN);
myDirectInputCreate=GetProcAddress(handle,"DirectInputCreateEx");
myDirectInputCreate(hWnd,DIRECTINPUT_VERSION,IID_IDirectInput7,
(void**)&dinput,NULL);

编译时出现错误，getprocaddress与mydirectinputcreate类型不同，请问如何改正。

try this way:

HANDLE handle=LoadLibrary("c:\\windows\\system\\dinput.dll");

typedef HRESULT (* DICREATE)(HINSTANCE,DWORD,REFIID,LPVOID*,LPUNKNOWN);

DICREATE myDirectInputCreate;

myDirectInputCreate = (DICREATE) GetProcAddress(handle,"DirectInputCreateEx");

myDirectInputCreate(hWnd,DIRECTINPUT_VERSION,IID_IDirectInput7,
(void**)&dinput,NULL);

谢谢答复,但我发现从dinput.dll中导出DirectInputCreateEx后,用inspect察看,dinput的
各成员均用问号表示,说明dinput创建不成功,请问是怎么回事?
