Thomas, If You place NULL in third parameter of the WritePrivateProfileString with NULL it will delete the key of that section, If You place NULL for second parameter it will delete entire section, i.e.:

   DECLARE INTEGER WritePrivateProfileString IN Win32API AS WritePrivStr ;
                                                            String cSection, String cKey, String cValue,;
                                                            String cINIFile
   WritePrivStr("TestSection","SomeKey",NULL,"c:\myIniFile.INI") && This will delete SomeKey key from INI file

   WritePrivStr("TestSection",NULL,NULL,"c:\myIniFile.INI") && It will delete Entire testSection
