C#一键获取并显示/隐藏第三方程序系统任务栏右下角托盘图标

admin

2024年3月19日 18:6 本文热度 597

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++（附件：spy++.zip）->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。

Win2API.cs，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。
