文件读取小问题

[chengliang80]

我要向一个文件中写入一个变量，例如money=999,写入的时候写入money=999,但读出的时候，读出999。我该怎么写入，怎么读出，麻烦写的详细点，我是个菜鸟。

用ini文件吧。

参考delphi 有关 "TiniFile" 的帮助

例子：：：
读
CIniFile Ini("个人计数器.ini");

Ini.ReadInteger("Noon","Noon hour",(long &)m_nnhour);
Ini.ReadInteger("Noon","Noon minute",(long &)m_nnminute);
Ini.ReadInteger("Noon","Noon second",(long &)m_nnsecond);

写
CIniFile Ini("个人计数器.ini");
Ini.WriteInteger("Color","background color",bgcolor);
Ini.WriteInteger("Color","edit frame color", editcolor);

[aicai]

自己试一试把！！！！
CIniFile Ini("个人计数器.ini");
中的“个人计数器.ini”是文件名！！！！

太详细了，不大好吧

用ini文件:
CString strFileName = _T("somefile.ini);
CString strSec = _T("variables");
CString strKey = _T("money");
int nMoney = 999;

写入时:
CString strMoney;
strMoney.Format(_T("%d"), nMoney);
WritePrivateProfileString(strSec, strKey, strMoney, strFileName);

读取时:
如果变量是数字:
UINT nMoneyRead = GetPrivateProfileInt(strSec, strKey, 0, strFileName);
如果是字符串:
CHAR szMoney[128];
GetPrivateProfileString(strSec, strKey, _T(""), szMoney, sizeof(szMoney)/sizeof(CHAR), strFileName);
