vs2008下实现二维码扫描，图片扫描，很好用，使用opencv，zbar库

vs2008下实现二维码扫描，图片扫描，很好用，使用opencv，zbar库。可以实现从工程目录下读取二维码图片进行扫描，也可以通过控制电脑摄像头进行扫描二维码，取其中一帧图片进行解析，解析结果与上次不同，则输出，大体是这样

// stdafx.cpp : source file that includes just the standard includes
// testOpencv.pch will be the pre-compiled header
// stdafx.obj will contain the pre-compiled type information

#include “stdafx.h“

// TODO: reference any additional headers you need in STDAFX.H
// and not in this file
