最近为了做公众号号推广,吸粉,然后加了几百个QQ群,感觉QQ群的群发效果还是不错的,一天能捞到100个粉丝左右,好的时候也有200个,少的时候几十个,但是由于太多的群了,手工一个个点击开来群发,几百个群,要花费大量的时间,所以想到了QQ群发工具,然后就在百度上搜索,最后发现网上很多QQ群发器根本用不了,本来想买一个的,因为太垃圾了,就不买了,而自己又是个程序员,干脆花点时间自己编写一个工具,经过两天奋战,终于把这个工具写好了,经测试,感觉还挺稳定的,这样我就可以解放双手了,现在我要把这编写的代码分享给大家。

新建窗体项目AssistWFA

由于界面部分代码比较多,很多代码都是系统自动生成的,没有必要贴代码。
我把截图贴上去:

主界面

一步步打造QQ群发消息群发器

 

设置界面

一步步打造QQ群发消息群发器

 

群列表界面

一步步打造QQ群发消息群发器

 

问候语界面

一步步打造QQ群发消息群发器

 

本群发器的特点:

  • 简单高效
  • 稳定
  • 配置参数少

功能使用注意:

  • 要打开所以群窗口,不可以合并窗口
  • 不支持锁屏挂机

就这么多,这是根据自己的需求编写的,功能比较简单,够用就行,关键是稳定,不掉线。
