 /// 你可以把它编译成dll在winform或webform中引用，也可以直接把代码拷到项目中使用

用java读写ini配置文件

??? 在java中,配置文件一般主要是两种形式:xml文件或者property文件.但大部分人都习惯使用ini文件,而且ini文件的分节以及注释功能,比起xml,也是易懂易用的. ??? 在vc中类库中有读写ini文件的标准函数.在dephi或其他语言中,也可以用windows的api函数来读写ini文件.但在java中似乎没有现成的类和方法可供使用.虽然java可以通过加载dll文件的方法来调用windows的api,但总觉得不够正宗. ??? 于是自己写了个读写ini配置文件的类,供大家参

C++读取INI配置文件类实例详解_C 语言

本文以实例讲解了C++读取配置文件的方法. 一般情况下,我们都喜欢使用ini扩展名的文件作为配置文件,可以读取及修改变量数值,也可以设置新的组,新的变量,本文的实例代码一个是读取INI的定义文件,另一个是CIniFile类实现文件,两者结合,完美实现VC++对INI文件的读写. 用户接口说明:在成员函数SetVarStr和SetVarInt函数中,当iType等于零,则如果用户制定的参数在ini文件中不存在,则就写入新的变量.当iType不等于零,则如果用户制定的参数在ini文件中不存在,就不写

一个.net下通用的Cookie操作类

笔者曾经参与一个大型多用户商城的开发,系统用户角色很多,有买家,卖家,代理商,系统管理员 ,普通管理员,超级管理员等,这些用户都涉及到登陆系统,然后建立cookies的问题,由于角色的不同 ,这些用户登陆系统后,所建的cookies都相对独立,而且对一个多用户商城来说,cookies区分域很重要 ,不同的域名要建不同的域.因此笔者在开发的过程中,写了很多次的建cookies,取cookies的代码,不 胜其烦! 既然都是建cookies,那么肯定有共同点,我们何不抽象出来,写一个通用的Cooki
