ini 文件里怎样删除记录

[guangjun]

例子：
[use]
use1=123
use2=123
use3=123

我想删除use2 请教大个们怎样

[microfire]

WritePrivateProfileString("use","use2",NULL,ini文件名.c_str());

[qibo999]

TIniFile *pWinIni = new TIniFile("c:\Windows\Win.ini");
if (Memo1->Lines->Values["Pattern"] == "")
pWinIni->DeleteKey("Desktop", "Pattern");
else
pWinIni->WriteString("Desktop", "Pattern", Memo1->Lines->Values["Pattern"]);
delete pWinIni;

[qibo999]

TIniFile *pWinIni = new TIniFile("c:\\abc.ini");
pWinIni->DeleteKey("use", "use2");

delete pWinIni;

DeleteKey

[microfire]

看看 win.ini 或 system.ini 就明白了，里面有那么多空键。
建议还是清空键值为好，

[gyj_china]

TIniFile *pWinIni = new TIniFile("path + filename.ini");
pWinIni->DeleteKey("use", "use2");
delete pWinIni;

记得带头文件IniFiles.h

同意qibo999(行路者) ， 使用deletekey

TIniFile *pWinIni = new TIniFile("your ini files");
pWinIni->DeleteKey("use", "use2");
delete pWinIni;
