如何在程序中调用Windows Mobile系统自带的控制面板项呢?经常在论坛或者邮件组看到这样的问题, 比如我们也许在自己的程序中需要添加一个“移除程序”功能，或者需要用户设置一下闹钟，或者需要修改一下其他的系统设置，这时候也许直接调用系统自带的控制面板，要比自己修改注册表自己设计消息存储方式自己设计UI要简单的多。

下面这个类就实现了这一功能：

class ControlApplet
{
    public static void ShowApplet(AppletType applet)
    {
        ProcessStartInfo startInfo = new ProcessStartInfo();
        startInfo.FileName = @"\Windows\ctlpnl.exe";
        startInfo.Arguments = String.Format("cplmain.cpl,{0}", (byte)applet);
        Process.Start(startInfo);
    }
   
     public static void ShowApplet(AppletType applet, byte tabIndex)
     {
         ProcessStartInfo startInfo = new ProcessStartInfo();
         startInfo.FileName = @"\Windows\ctlpnl.exe";
          startInfo.Arguments = String.Format("cplmain.cpl,{0},{1}", (byte)applet,tabIndex);
           Process.Start(startInfo);
       }

       public enum AppletType
       {
           Contrast,
           Password,
           OwnerInformation,
           Power,
           Memory,
           About,

           Buttons,
           TodaySettings,
           PCConnections,
           ModemConnections,
           Clock,
           NetworkConnections,
           RegionalSettings
       }
