用SkinSB美化滚动条控件
尝试了很多方法来美化滚动条，但是都不是很理想。网上学习了用SkinSB来美化，简单好用，效果理想。

从哪里获取Detours?
它依赖着微软的一个很暴力的库Detours,可以从微软的网站上获取到:http://research.microsoft.com/en-us/projects/detours/
官方网站上Detours最新版本是2.1,而SkinSB原生用的是1.5的版本的,这两个版本的API差异还是很大的,所以头文件对此做了一个桥接,以下为头文件的代码:
#ifndef __SkinsbHelper_H__
#define __SkinsbHelper_H__
//
包含头文件
#include "detours.h"
#include "skinsb.h"
#if defined(_DEBUG)
#pragma comment(lib, "skinsb.lib")
#pragma comment(lib, "detours.lib")
#else
#pragma comment(lib, "skinsb.lib")
#pragma comment(lib, "detours.lib")
#endif
//
//
申明钩子
//
#if (DETOURS_VERSION >= 20100)

在InitInstance()里面使用:RegisterSkinSB(),
在RegisterSkinSB中使用;UnRegisterSkinSB().
