ZKemKeeper：不触发的事件

Question

我正在构建一个C＃windows应用程序以获得拇指印象并将其显示在窗体上。我已成功将应用程序连接到扫描仪（ZKTeco TX628）。但是，事件不会触发。

这里是我的代码： -

ZKFPEngX fp = new ZKFPEngX(); 
    zkemkeeper.CZKEMClass axCZKEM1 = new zkemkeeper.CZKEMClass(); 
    bool bIsConnected = false; 

    public Form2() 
    { 
     InitializeComponent(); 
    } 

    private void button1_Click(object sender, EventArgs e) 
    { 
     bIsConnected = axCZKEM1.Connect_Net("192.168.1.201", Convert.ToInt32(4370)); 

     if (bIsConnected == true) 
     { 
      if (axCZKEM1.RegEvent(1, 65536)) 
      { 
       this.axCZKEM1.OnFinger += new zkemkeeper._IZKEMEvents_OnFingerEventHandler(axCZKEM1_OnFinger); 
       this.axCZKEM1.OnConnected += new _IZKEMEvents_OnConnectedEventHandler(axCZKEM1_OnConnected); 
       this.axCZKEM1.OnVerify += new zkemkeeper._IZKEMEvents_OnVerifyEventHandler(axCZKEM1_OnVerify); 
      } 
     } 
     else 
     { 
      int idwErrorCode=-1; 
      this.axCZKEM1.GetLastError(ref idwErrorCode); 
      MessageBox.Show("Unable to connect the device,ErrorCode=" + idwErrorCode.ToString(), "Error"); 
     } 
    } 

    private void axCZKEM1_OnFinger() 
    { 
     label1.Text = "OK"; 
     byte[] TmpData = new byte[700]; 
     int with = 0; 
     int lenth = 0; 
     bool fulimage = false; 
     string path = ""; 
     byte a=1; 
     axCZKEM1.CaptureImage(fulimage, ref with, ref lenth, ref a, path); 
     MessageBox.Show ("RTEvent OnFinger Has been Triggered"); 
    } 

    private void axCZKEM1_OnVerify(int uid) 
    { 
     label1.Text = "Verified"; 
    } 

    private void axCZKEM1_OnConnected() 
    { 
     label1.Text = "Connected"; 
    } 

    private void button2_Click(object sender, EventArgs e) 
    { 
     this.axCZKEM1.EnableDevice(1, true); 

     this.axCZKEM1.Disconnect(); 
     label1.Text = "Disconnected"; 
    }

   bIsConnected = axCZKEM1.Connect_Net("192.168.1.201", Convert.ToInt32(4370)); 

      if (bIsConnected == true) 
      { 
       Trace.subWriteInLogFile(string.Concat(DateTime.Now.ToString(formatDateLog), "| " + "Connected")); 

       iMachineNumber = 1;//In fact,when you are using the tcp/ip communication,this parameter will be ignored,that is any integer will all right.Here we use 1. 
       if (axCZKEM1.RegEvent(iMachineNumber, 65535))//Here you can register the realtime events that you want to be triggered(the parameters 65535 means registering all) 
       { 
        this.axCZKEM1.OnFinger += new zkemkeeper._IZKEMEvents_OnFingerEventHandler(axCZKEM1_OnFinger); 
        this.axCZKEM1.OnVerify += new zkemkeeper._IZKEMEvents_OnVerifyEventHandler(axCZKEM1_OnVerify); 
        this.axCZKEM1.OnAttTransactionEx += new zkemkeeper._IZKEMEvents_OnAttTransactionExEventHandler(axCZKEM1_OnAttTransactionEx); 
        this.axCZKEM1.OnFingerFeature += new zkemkeeper._IZKEMEvents_OnFingerFeatureEventHandler(axCZKEM1_OnFingerFeature); 
        this.axCZKEM1.OnEnrollFingerEx += new zkemkeeper._IZKEMEvents_OnEnrollFingerExEventHandler(axCZKEM1_OnEnrollFingerEx); 
        this.axCZKEM1.OnDeleteTemplate += new zkemkeeper._IZKEMEvents_OnDeleteTemplateEventHandler(axCZKEM1_OnDeleteTemplate); 
        this.axCZKEM1.OnNewUser += new zkemkeeper._IZKEMEvents_OnNewUserEventHandler(axCZKEM1_OnNewUser); 
        this.axCZKEM1.OnHIDNum += new zkemkeeper._IZKEMEvents_OnHIDNumEventHandler(axCZKEM1_OnHIDNum); 
        this.axCZKEM1.OnAlarm += new zkemkeeper._IZKEMEvents_OnAlarmEventHandler(axCZKEM1_OnAlarm); 
        this.axCZKEM1.OnDoor += new zkemkeeper._IZKEMEvents_OnDoorEventHandler(axCZKEM1_OnDoor); 
        this.axCZKEM1.OnWriteCard += new zkemkeeper._IZKEMEvents_OnWriteCardEventHandler(axCZKEM1_OnWriteCard); 
        this.axCZKEM1.OnEmptyCard += new zkemkeeper._IZKEMEvents_OnEmptyCardEventHandler(axCZKEM1_OnEmptyCard); 
        Trace.subWriteInLogFile(string.Concat(DateTime.Now.ToString(formatDateLog), "| " + "Events registred")); 

       } 
      } 
      else 
      { 
       axCZKEM1.GetLastError(ref idwErrorCode); 

       Trace.subWriteInLogFile(string.Concat(DateTime.Now.ToString(formatDateLog), "| " + "Unable to connect the device, ErrorCode = " + idwErrorCode.ToString())); 

      }
