Server.ini文件：
[General]
FastStart=1
Changeler=1233
ChangellerA=1234
操作：
CString m_strAppPath,m_strIni;
char buf[MAX_PATH];
::GetModuleFileName(NULL,buf,sizeof(buf));
CString str=buf;
int m=str.ReverseFind('//');
m_strAppPath=str.Left(m+1);
str.Empty();
double dOldVersion=0;
m_strIni = m_strAppPath + _T("//Server.ini");
//取为字符串
::GetPrivateProfileString("General","Changeler","0",buf,sizeof(buf),m_strIni);
//取为整型值
int nget;
nget = GetPrivateProfileInt("General","FastStart",0,m_strIni);
//写INI值
WritePrivateProfileString("General","H323InAuthPrefix",m_strIni,m_strIni);
