Lync二次開發關於Lync啓動退出問題

以前使用C++開發的version.dll文件，由於各個用戶環境的不同，造成某些用戶加載不了我們開發的插件，並且寫version.dll的同事還沒找到好的解決辦法，所以得換一種思路去解決這個問題，就是Lync啓動時加載我們的插件。

因此寫了一個winform程序來監控進程的變化，這個程序還要設置爲開機啓動。下面是主要代碼：

 1 static class Program
 2     {
 3         public static System.Threading.Mutex _run;
 4         /// <summary>
 5         /// 應用程序的主入口點。
 6         /// </summary>
 7         [STAThread]
 8         static void Main()
 9         {
10             bool noRun = false;
11             _run = new System.Threading.Mutex(true, "ICOLyncWindow", out noRun);
12             if (noRun)
13             {
14                 _run.ReleaseMutex();
15                 try
16                 {
17                     //處理未捕獲的異常   
18                     Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException);
19                     //處理UI線程異常   
20                     Application.ThreadException += new System.Threading.ThreadExceptionEventHandler(Application_ThreadException);
21                     //處理非UI線程異常   
22                     AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException);
23 
24                     Application.EnableVisualStyles();
25                     Application.SetCompatibleTextRenderingDefault(false);
26                     Application.Run(new IcoLyncForm());
27                 }
28                 catch (Exception ex)
29                 {
30                     Logger.Error(ex);
31                 }
32             }
33         }
34 
35         static void Application_ThreadException(object sender, System.Threading.ThreadExceptionEventArgs e)
36         {
37             Logger.Error(e.Exception);
38         }
39 
40         static void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
41         {
42             Logger.Error(e.ExceptionObject as Exception);
43         }
44     }

44             try
45             {
46                 do

88             Process.GetCurrentProcess().Kill();
89         }
90     }

這個winform程序啓動之後調用win32 api隱藏起來。檢測到新增Lync.exe進程時，註冊ICOLync插件，Lync.exe進程註銷後，重啓winform程序。開始還考慮把winform程序的進程保護起來，很麻煩，不同的操作系統，出現的狀況還不一樣，所以取消了。

 

2013.7.26修改：

使用System.Threading.Mutex互斥體，實現程序只啓動單一進程，發現有一個Bug，在windows多用戶的情況下，每一個用戶都可以啓動一個進程，所以要保持整天計算機只啓動一個進程，應改爲如下：
