本文展示了一个使用C++在Windows环境下通过GetPrivateProfileString和WritePrivateProfileString函数读取和写入INI配置文件的具体例子。该示例包括了如何获取程序路径、构造配置文件路径及读写配置项如短信中心号码、IP地址、端口号等。

TCHAR exeFullPath[MAX_PATH]; // MAX_PATH在API中有定义，为128 int len=GetModuleFileName(NULL, exeFullPath, //应用程序的全路径存放地址 MAX_PATH); CString path="//config.ini"; //配置文件名 ::strcpy(exeFullPath+len-12,path); //组合出配置文件的全路径

//读取

CString szComCheck ; CString szBaud ; GetPrivateProfileString("短信中心号码", "SMSC","+8613800280500", strSMSC.GetBuffer(MAX_PATH),MAX_PATH,exeFullPath); GetPrivateProfileString("IP地址", "IP","127.0.0.1",strIP.GetBuffer(MAX_PATH),MAX_PATH,exeFullPath); GetPrivateProfileString("网络端口号", "NetPort","",strNetPort.GetBuffer(MAX_PATH),MAX_PATH,exeFullPath); GetPrivateProfileString("定时周期", "TimeCycle","",strTimeCycle.GetBuffer(MAX_PATH),MAX_PATH,exeFullPath); for(int i=0; i<8; i++) { szComCheck.Format("COMCheck%d",i); GetPrivateProfileString("串口选中状态", szComCheck,"0", strCheck[i].GetBuffer(MAX_PATH),MAX_PATH,exeFullPath); szBaud.Format("Baud%d",i); GetPrivateProfileString("波特率", szBaud ,"9600", strBaud[i].GetBuffer(MAX_PATH),MAX_PATH,exeFullPath); }

TCHAR exeFullPath[MAX_PATH]; // MAX_PATH在API中有定义，为128 int len=GetModuleFileName(NULL, exeFullPath, //应用程序的全路径存放地址 MAX_PATH); CString path="//Config.ini"; //配置文件名 ::strcpy(exeFullPath+len-12,path); //组合出配置文件的全路径

//存入 CString szComCheck ; CString szBaud ; WritePrivateProfileString("短信中心号码", "SMSC", strSMSC,exeFullPath); WritePrivateProfileString("IP地址", "IP",strIP,exeFullPath); WritePrivateProfileString("网络端口号", "NetPort",strNetPort,exeFullPath); WritePrivateProfileString("定时周期", "TimeCycle",strTimeCycle,exeFullPath); for(int i=0; i<8; i++) { szComCheck.Format("COMCheck%d",i); WritePrivateProfileString("串口选中状态", szComCheck, strCheck[i],exeFullPath); szBaud.Format("Baud%d",i); WritePrivateProfileString("波特率", szBaud , strBaud[i],exeFullPath); }
