Timer刷新问题

[AwL_1124]

功能：
用定时器，每隔多少秒刷新path下文件内容到Textbox
VS2010的Windows Froms Application
这是在button1_Click中的方法

 			 //调用刷新方法来定时分析数据
			 refrushClass^ re = gcnew refrushClass;
			 path = "c:\\SceneServer.log5696";
			 re->Main(path);

refrushClass类(与public ref class Form1 : public System::Windows::Forms::Form在同一源码中)：

	public ref class refrushClass
	{
		private:
	   static System::Windows::Forms::Timer^ myTimer = gcnew System::Windows::Forms::Timer;
	   static int alarmCounter = 1;
	   static String^ pathRefrush;
	   static String^ strTotal;
	   // This is the method to run when the timer is raised.
	   static void TimerEventProcessor( Object^ /*myObject*/, EventArgs^ /*myEventArgs*/ )
	   {
		  myTimer->Stop();
		  myTimer->Enabled = true;
		  //读取path文件内容
		  StreamReader^ sr = File::OpenText(pathRefrush);
		  try
		  {
			  //临时存放每次读取到的文件
			  String^ s = "";
			  while (s = sr->ReadLine())
			  {
				  strTotal += s;
			  }
		  }
		  finally
		  {
			  if (sr)
			  {
				  //释放缓存文件
				  delete (IDisposable^)(sr);
			  }
		  }
		  /*不知道怎么把strTotal传递到指定的textbox中,textbox无法直接在此引用*/
	   }


	public:
	   static void Main(String^ path)
	   {
		   pathRefrush = path;
		  /* Adds the event and the event handler for the method that will 
					process the timer event to the timer. */
		  myTimer->Tick += gcnew EventHandler( TimerEventProcessor );

		  // Sets the timer interval to 5 seconds.
		  myTimer->Interval = 5000;
		  myTimer->Start();

		  // 调用TimerEventProcessor()方法
		  while(true)
		  {
			  Application::DoEvents();
		  }
   }
	};

设计思路：
通过TimerEventProcessor方法来定时读取Path中的内容，但不知道如何传递到textbox控件中

[真相重于对错]

弄一个form1 的全局变量
