資源簡介
1. 下載本實例源碼
2. 安裝注意事項
在配置檔中配置你要守護的應用程序，應用程序之間用逗號隔開：
01 <?xml version="1.0" encoding="utf-8" ?>
02 <configuration>
03 <appSettings>
04 <add key="ProcessAddress" value="
05 d:\war3.exe,
06 d:\note.txt,
07 d:\girl.jpg
08 " />
09 </appSettings>
10 </configuration>
該項目是Windows服務，直接打開“CocoWatcher.exe”會報錯，如圖1所示：
1 "%cd%\InstallUtil.exe" "%cd%\CocoWatcher.exe"
2 net start "CocoWatcher"
3 pause
如果你想卸載該守護程序，點擊批處理文檔“卸載.bat”，“卸載.bat”具體內容如下：
1 net stop "CocoWatcher"
2 "%cd%\InstallUtil.exe" "%cd%\CocoWatcher.exe" -u
3 taskkill /f /im CocoWatcher.exe
4 pause
3. 需求分析
用戶指定要守護的應用程序(數量不限)，該應用程序不僅包括exe可執行文件，還包括諸如jpg、txt等所有能雙擊打開執行的應用程序。用戶設定好要守護的應用程序后，關閉應用程序(包括合法和非法關閉)，該應用程序要能立即重啟打開。當電腦重啟時，要守護的應用程序也能自動全部打開。
4. 詳細設計
要實現上述需求，首先要提供一個配置檔，讓用戶能隨意配置要守護的應用程序。那么，該配置檔要配置應用程序的什么信息呢？答案：應用程序的全路徑。
好，我們已經知道了要守護的應用程序的全路徑，接下來怎樣完成守護任務呢？首先，我們應該打開任務管理器，查看一下正在運行的有哪些進程，然后逐一讀取出這些進程的全路徑，與要守護的應用程序的全路徑比對，如果一致，說明要守護的應用程序已開啟了，此時要分配一條線程監控該進程句柄，當該進程句柄返回信息，說明該進程已關閉，此時釋放進程句柄內存，并重啟該進程。如果遍歷任務管理進程列表中所有進程，沒有找到與要守護的應用程序的全路徑一致的進程，說明要守護的應用程序尚未打開，此時要啟動該應用程序，然后轉入監控流程。
值得注意的是，一定要額外分配線程去監控要守護的應用程序，為什么？因為如果你用主線程(入口函數線程)去執行監控任務，會被長期阻塞，直到進程退出才會被激活，這樣就無法運行后續程序。況且，監控程序要實現持續監控，要使用死循環，如果主線程進入死循環，就無法監控其他要守護的進程了。
