【經典】WinCE下系統托盤程序之聲音控制篇

 

程序在以下平臺測試通過：

操作系統：Wince6.0

軟件平臺：EVC4.0

硬件平臺：深圳友堅恆天科技有限公司ARM11開發板UT-S3C6410

在XP下我們能經常看到系統托盤的圖標，也就是右下角的小圖標，比如：QQ圖標、音量控制圖標等，那麼Wince下的如何實現系統托盤呢？本文通過圖解＋代碼的方式詳細介紹系統托盤程序實現的整個步驟。

 

 

先來看看程序實現後的效果圖：

 

1、  開機自動運行系統托盤程序

2、  左鍵單擊圖標（小喇叭），上下拖動調整音量大小

 

3、  點擊“Mute“靜音

 

4、  雙擊打開系統音量控制界面

 

步驟：

1、  EVC下建立一個WCE Application Project

點擊ok

2、  選擇A Sample Windows CE Application

點擊“Finish”

3、  創建並編輯對話框資源

 

4、  插入兩個托盤ICON

一個是正常狀態，一個是靜音狀態

 

 

程序很簡單，主要包括幾個方面：

1、  自定義一個消息用來處理系統托盤的操作

2、  初始化NOTIFYICONDATA結構

3、  調用API函數Shell_NotifyIcon

4、  系統托盤消息處理

 

5、 將編譯生成的SoundSystemTray.exe拷貝至Wince 工程目錄下

6、 將在SoundSystemTray.exe 加到NK中

platform.bib中添加

SoundSystemTray.exe $(_FLATRELEASEDIR)/SoundSystemTray.exe  NK S

7、 設置開機自動運行SoundSystemTray.exe

platform.reg中添加

[HKEY_LOCAL_MACHINE/Init]

"Launch80"="SoundSystemTray.exe"

"Depend80"=hex:1e,00
