一、环境
Visual Studio 2012，DirectX SDK (June 2010)
二、准备
1.环境变量（如没有配置请添加）
变量名：DXSDK_DIR
变量值：D:\Software\Program\Microsoft DirectX SDK (June 2010)
这里D:\Software\Program\Microsoft DirectX SDK (June 2010)是我的DirectX安装目录，视情况修改即可
三、步骤
1.打开VS2012，创建一个空的Win32 Project
这里的项目名称（Name）可以自定义，项目位置（Location）可能不同，不过没关系，可以不用修改
点击OK，然后点击Next，勾选Empty Project
点击Finish，完成项目创建。
2.打开项目属性（Properites），配置项目的DirectX环境
主要需修改的项：Configuration Properites->VC++ Directories，Configuration Properites->Linker->General，Configuration Properites->Linker->Input
VC++ Directories：（注意后面的分号）
Include Directories项中添加$(DXSDK_DIR)\Include;
Library Directories项中添加$(DXSDK_DIR)\Lib\x86;
Linker->Input：添加以下三个lib文件d3d9.lib d3dx9.lib Winmm.lib，添加时注意用分号隔开，如下：
d3d9.lib;d3dx9.lib;Winmm.lib;
Linker->General：AdditionalLibrary Directories项中添加$(DXSDK_DIR)\Lib\x86 （可以不加分号）
点击确定应用以上更改。
3.打开Source.cpp，复制以下代码：
1 #include <d3dx9.h>
2 IDirect3DDevice9* Device=0;
3 LRESULT CALLBACK WndProc(HWND hwnd,UINT msg,WPARAM wParam,LPARAM lParam)
4 {
5 switch(msg)
6 {
7 case WM_DESTROY:PostQuitMessage(0);break;
8 case WM_KEYDOWN:
9 if(wParam==VK_ESCAPE)DestroyWindow(hwnd);break;
10 }
11 return DefWindowProcW(hwnd,msg,wParam,lParam);
12 }
13 bool Init(HINSTANCE hInstance,int width,int height,bool windowed,D3DDEVTYPE devType,IDirect3DDevice9** device)
14 {

72 d3d9->Release();
73 return false;
74 }
75 d3d9->Release();
76 return true;
77 }
78 int EnterMsgLoop(bool (*ptr_display)(float TimeDelta))
79 {
80 MSG msg;
81 ZeroMemory(&msg,sizeof(MSG));
82 float LastTime=(float)GetCurrentTime();
83 while(msg.message!=WM_QUIT)
84 {
85 if(PeekMessageW(&msg,0,0,0,PM_REMOVE))
86 {
87 TranslateMessage(&msg);
88 DispatchMessageW(&msg);
89 }
90 else
91 {
92 float CurTime=(float)GetCurrentTime();
93 float TimeDelta=(float)(CurTime-LastTime)*0.001f;
94 ptr_display(TimeDelta);
95 LastTime=CurTime;
96 }
97 }
98 return msg.wParam;
99 }
100 bool Setup()
101 {
102 return true;
103 }
104 void Cleanup()
105 {
106
107 }
108 bool Display(float TimeDelta)
109 {
110 if(Device)
111 {
112 Device->Clear(0,0,D3DCLEAR_TARGET|D3DCLEAR_ZBUFFER,0x00000000,1.0f,0);
113 Device->Present(0,0,0,0);
114 }
115 return true;
116 }
117 int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE prevInstance,PSTR cmdLine,int showCmd)
118 {
119 if(!Init(hInstance,640,480,true,D3DDEVTYPE_HAL,&Device))
120 MessageBoxW(0,L"Init Failed",0,0);
121 if(!Setup())MessageBoxW(0,L"Setup Failed",0,0);
122 EnterMsgLoop(Display);
123 Cleanup();
124 Device->Release();
125 return 0;
126 }
点击Local Windows Debugger编译项目，运行结果如下：
至此，第一个Direct3D程序已经完工。
