vs2013 MFC自己封装的CMyKey类

从vc6.0转到vs2013，原先都是ANSI字符编码，现在vs默认的是Unicode编码。MessageBox("test");都要改成MessageBox(_T("test"));很麻烦！其他方面就不说了。

看到推酷的一篇文章 http://www.tuicool.com/articles/IbEZBr 《对多字节字符编码的支持》是从http://blog.csdn.net/xinzhiyounizhiyouni/article/details/20617981转的。

这句是重点：使vs2013支持多字节字符，这个就需要下载和安装一个文件 http://pan.baidu.com/s/1Acu6M。然后：在项目属性中，把字符集改成多字节字符集。

搞定编码了，接下来就是介绍CMyKey类。

测试结果：

测试代码（都是放在按钮的单击事件中的）：

void CRegister测试View::OnTest(){//MessageBox("show?");//字符串型 获取char str[MAX_PATH] = { '\0' };BOOL result = key1.GetK(HKEY_CURRENT_USER, "Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\TypedPaths", "url1", str);if (result){MessageBox(str);//C:\Users\sophsis\AppData\Roaming\yxj.exe}else{MessageBox("error!");}/*//数值型 获取DWORD value = 20;CString str;if (key1.GetK(HKEY_CURRENT_USER, "Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\StartPage2", "FavoritesVersion", value)){str.Format("value=%d", value);//value=2MessageBox(str);}else{MessageBox("error");//失败则经过这里}*///修改字符串型//key1.WriteK(HKEY_CURRENT_USER,"Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\TypedPaths","url1","test");//修改整数型//key1.WriteK(HKEY_CURRENT_USER,"Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\StartPage2","FavoritesVersion",3);//删除//key1.DelK(HKEY_CURRENT_USER,"Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\TypedPaths","url1");//key1.DelK(HKEY_CURRENT_USER,"Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\StartPage2","FavoritesVersion");}
