Directx3d9——CreateDevice（原）
1.DirectX SDK 下载地址：http://www.microsoft.com/downloads/en/details.aspx?displaylang=en&FamilyID=3021d52b-514e-41d3-ad02-438a3ba730ba
2.安装SDK
3.以vs2010为例子，配置开发环境。
首先，创建win32工程，然后修改工程的属性。以下是工程的属性页。修改包含目录和库目录。
在链接->输入：
d3d9.lib
d3dx10d.lib
d3dx9d.lib
dxerr.lib
dxguid.lib
winmm.lib
comctl32.lib
