[原创]C#一键隐藏QQ/MSN,显示/隐藏系统托盘图标,获取托盘图标


本程序所实现功能
   1.显示/隐藏Windows系统托盘图标
   2.显示/隐藏QQ聊天窗体及托盘图标
   3.显示/隐藏MSN聊天窗体及托盘图标
   4.显示/隐藏当前打开的窗体

一键隐藏QQ/MSN,显示/隐藏系统托盘图标技术难度较大,所以作为主要介绍对象。

显示隐藏系统括盘图标

我们先来分析QQ/MSN窗体特性:

打开VS->工具->Spy++->Spy\Windows,看下图:

Spy++QQ窗体特性截图:

Spy++MSN窗体特性截图:

好了,知道QQ及MSN窗体信息后通过一堆WindowsAPI来枚举所有窗体。直到找出符合上面条件的窗体。

WinAPI函数定义类,函数说明这里不写了,如有不懂的自己上MSDN中文网搜搜。
