文件读取小问题
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:
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);
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);

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！！！！
CIniFile Ini("个人计数器.ini");
中的“个人计数器.ini”是文件名！！！！

用ini文件吧。
