关于OD 插件开发的相关api请到网上查阅，这里只给出一个简单基础的例子。

1、新建一个dll工程。

2、创建一个对话框，如图

3、资源文件头如下：

//{{NO_DEPENDENCIES}}
// Microsoft Visual C++ generated include file.
// Used by odplugin1.rc
//
#define IDD_TEST                        101
#define IDC_EDIT1                       1001
#define IDC_BUTTON1                     1002
#define IDC_QUIT                        1002

// Next default values for new objects
// 
#ifdef APSTUDIO_INVOKED
#ifndef APSTUDIO_READONLY_SYMBOLS
#define _APS_NEXT_RESOURCE_VALUE        102
#define _APS_NEXT_COMMAND_VALUE         40001
#define _APS_NEXT_CONTROL_VALUE         1003
#define _APS_NEXT_SYMED_VALUE           101
#endif
#endif

4、程序代码如下;

// dllmain.cpp : Defines the entry point for the DLL application.
#include "stdafx.h"
#include <windows.h>
#include "resource.h"
#include "Plugin.h"

#pragma comment(lib,"Ollydbg.lib")
#pragma comment(lib, "user32.lib")
//#pragma comment(lib, "Gdi32.lib")

//global variant
static char g_szPluginName[] = "Matrix";
static HWND g_hWndMain = NULL;  //保存OD主窗口句柄
static HINSTANCE g_hModule = NULL;  //保存dll句柄
static char g_szMatrixClass[32];

	else if( uMsg == WM_COMMAND)

	return TRUE;

	return 0;
}

{
	if(origin == PM_MAIN)
	{
		switch(action)
		{
		case 0:     //这里的索引0  对应strcpy(data, "0 Matrix | 1 About");中的0
			DialogBox(g_hModule, MAKEINTRESOURCE(IDD_TEST), g_hWndMain, (DLGPROC)DlgOptionProc); //创建对话框
			break;
		case 1:
			MessageBoxA(
				g_hWndMain,

				MB_OK);
			break;

	}
}
