如何使用VC++写一个小程序来检测.NetFrameWork版本

Answer 1

如何使用VC来检测系统上的.NetFrameWork版本呢，原理见我前面刚刚写过，不懂的可以去看一下，下面直接贴代码了，百度呀，为什么没有贴代码的功能呢，哎直接贴真恶心呀，那就恶心一下吧。
#include “stdio.h”
#include “windows.h”
#include “tchar.h”
#include “strsafe.h”
#include “stdafx.h”

// 为避免机器编译时候出现：SDK中某些值没有被定义的情况，先定义他们。
#ifndef SM_TABLETPC
#define SM_TABLETPC 86
#endif
#ifndef SM_MEDIACENTER
#define SM_MEDIACENTER 87
#endif
// 用于检测注册表项的名称和值名称的常量
const TCHAR *g_szNetfx10RegKeyName = _T(“Software\\Microsoft\\.NETFramework\\Policy\\v1.0″);
const TCHAR *g_szNetfx10RegKeyValue = _T(“3705″);
