在MFC的CWinApp类的启动成员函数中，会有一个SetRegistryKey函数，在注册表中为程序设置一个主键。配合WriteProfileInt等函数，对程序的配置文件进行读写。

SetRegistryKey(_T(
""
));
//有这句,读写将会针对INI文件进行
//指定自己的INI文件名，否则编译器将以程序名称命名INI文件
free
((
LPTSTR
)theApp.m_pszProfileName);
theApp.m_pszProfileName = (
LPCTSTR
)
malloc
(256);
_tcscpy ((
LPTSTR
)theApp.m_pszProfileName ,_T(
"ScaleWeight"
));
