原本在vc++6.0中编译通过的项目，在转成vc++.net 后编译没通过．请教高手，

问题：
#include <dinput.h>
．．．
．．．
BOOL CDirectInput::Create( HINSTANCE hInst, HWND hWnd )
{
    HRESULT hr;

    // Create DirectInput object
    hr = DirectInputCreate(hInst, DIRECTINPUT_VERSION, &m_pDI, NULL);
    
    if( FAILED(hr) )
        return FALSE;
．．．
．．．
}

出现错误：
error C3861:'DirectInputCreate':identifier not found, even with argument-dependent lookup

已在　Project->Properties->Linker->Input->Additional Dependencies 里添加了
dxguid.lib
ddraw.lib
dinput.lib
dsound.lib

另directx 版本是9.0c

Thanks a lot!
