direct3d 出错了

BibleWang

我用的是c++builder 6
代码如下

                        return E_FAIL;
                }
         return S_OK;      
}
void Cleanup()
{
        if(NULL!=g_pd3dDevice)
        if(g_pd3dDevice->Release())
        g_pd3dDevice=NULL;

        if(NULL!=g_pD3D)

}

        g_pd3dDevice->Clear(0,NULL,D3DCLEAR_TARGET,D3DCOLOR_XRGB(128,128,128),1,0);
        g_pd3dDevice->BeginScene();
        g_pd3dDevice->EndScene();
        g_pd3dDevice-&gtresent(NULL,NULL,NULL,NULL);
}


//---------------------------------------------------------------------------
__fastcall TForm1::TForm1(TComponent* Owner)
        : TForm(Owner)
{
}
//---------------------------------------------------------------------------



void __fastcall TForm1::RenderTimerTimer(TObject *Sender)
{
Render();
}
//---------------------------------------------------------------------------
void __fastcall TForm1::FormDestroy(TObject *Sender)

}
//---------------------------------------------------------------------------
void __fastcall TForm1::Button1Click(TObject *Sender)

}
//---------------------------------------------------------------------------
错误如下
[Linker Error] Unresolved external 'Direct3DCreate9' referenced from E:\PROJECTS\3DMODELEDITOR\UNIT1.OBJ

为十么会出现这样的错误，我加了$(d3d9)\Lib;$(BCB)\Lib;$(BCB)\Bin;$(BCB)\Imports;$(BCB)\Projects\Bpl;$(BCB)\Projects\Lib

把dx9sdk的目录加入到开发环境中
为什么不用.net2003呢？

我用的是c++builder，不是vc++,不能加目录
