vs2008+DirectX9.0 第一个程序

1、开发环境：Vs2008, DirectX9.0

 

2、DirectX下载地址：http://www.crsky.com/soft/153.html ，五百多兆，安装。

 

3、环境配置：

    1).  在VS2008里面选择: ”工具”-->”选项”-->”项目和解决方案”-->”vc++目录”

    2). 在”显示以下内容的目录”下的下拉框中选择"包含文件"中插入新行选择"C:/Program Files/Microsoft DirectX SDK (March 2009)/Include”

    3).在”显示以下内容的目录”下的下拉框中选择”库文件”插入新行并选择"C:/Program Files/Microsoft DirectX SDK (March 2009)/Lib/x86”

 

4、新建项目：

    1). File-->New-->Project-->Other Languages-->Visual C++-->Win32-->Win32 Project，取名HelloWorld，如图：

   

 

    2). 点击ok，然后Next，选中Windows Application和Empty Project，然后Finish。  

   

 

    3). 在工程中，右键点击HelloWorld-->Add-->New Item-->C++ File，取名myFile.cpp。

   

 

    4).  将如下内容copy至myFile.cpp中。

5). 编译，执行，效果如图：
