CEF加载FLASH插件时弹出CMD命令行窗口的问题

这个是flash插件的一个bug，CEF（chromium系列浏览器）关闭sandbox第一次加载flash插件就会跳出这样的一个提示，在Google官方也看到了chromium的issue: 

解决方案

官方暂时未解决这问题，只能是自己修改代码，通过hook命令行启动函数来实现不让命令行启动，hook库有
微软的牛逼 Detours 但是要票票的，Esayhook 就是个不错的选择，32和64位都支持，开放源码使用简单。
MHOOK据说小而好用但不研究了。

代码

#include "stdafx.h"

using namespace std;

HOOK_TRACE_INFO hAHookTrackInfo = { NULL }; // keep track of our hook
HOOK_TRACE_INFO hWHookTrackInfo = { NULL }; // keep track of our hook

//注意调用约定 WINAPI，否则会出现堆栈异常
