一个操作Ini文件的类

【VB源码推荐：一个操作Ini文件的类】

'--------cIniFile.cls 代码----------------
'这里定义了一个cIniFile类

'// the path of our ini file

'--------cIniFile.cls 使用举例----------------

    Dim myIniFile As New cIniFile
    
    '---指定访问的ini文件
    If Len(App.Path) > 3 Then
        'under disk root dir , eg: "C:/"
        myIniFile.INIFile = App.Path & "/setting.ini"
    Else
        myIniFile.INIFile = App.Path & "setting.ini"
    End If
    
    '---写入ini文件
    myIniFile.WriteFile "setting", "username", strUser
   
    '---读出ini文件的数据
    '    注意，如果是字符串，则去掉末尾一个字符
    '                              [e-mail]
    strUser = Trim(myIniFile.GetFile("setting", "username"))
    strUser = Left(strUser, Len(strUser) - 1)
