求助，VC2010游戏编程无法载入磁盘位图？

[a86632678]

我刚刚开始学游戏编程，用的是VC2010。在基本的Direct3D 那里遇到了问题，利用LPDIRECT3DSURFACE9 载入磁盘位图时失败，提示


错误 1 error LNK2019: 无法解析的外部符号 _D3DXLoadSurfaceFromFileA@32，该符号在函数 "bool __cdecl Game_Init(struct HWND__ *)" (?Game_Init@@YA_NPAUHWND__@@@Z) 中被引用 E:\workspace\GameT1\Create_Surface\Create_Surface\winmain.obj Create_Surface


请问如何解决问题，谢谢了

程序代码如下：

求大神帮解决。谢谢了

1 D3DXCreateTextureFromFile( Device, TEXT("crate.jpg"), &Tex); 函数是这样用的。 2 Project->xxx properties->Configuration Properties->Linker->Input->Additional Dependencies + d3d9.lib d3dx9.lib winmm.lib Tools->Options->Projects and Solutions->VC++ Directories->win32 Include files + DirectXSDK安装目录\Include DirectX SDK 需安装， 上面以D3D9为例。 这个网址你可以参考下：http://wenku.baidu.com/view/4b7f2243be1e650e52ea9985.html。 后面写了配置的问题。

求大神指点下 我用这个函数不行啊。
