我在调用 Zkemkeeper.dll 中的事件时遇到了麻烦。我已成功建立连接,但是将手指放在传感器上时没有触发任何事件。事实上,没有触发实时事件。
任何帮助将不胜感激以下是我的代码;
private void button2_Click(object sender, EventArgs e)
{
string s = "";
int Val = 0;
bool bIsConnected = false;
try {
//zkemkeeper.CZKEMClass axczkem1 = new zkemkeeper.CZKEMClass();
// bIsConnected = axczkem1.Connect_USB(1);
bIsConnected = axczkem1.Connect_Com(6,1,115200);
if(bIsConnected==true){
Cursor = Cursors.Default;
bool asa= axczkem1.EnableDevice(1, true);
if (axczkem1.RegEvent(1, 65535))
{
axczkem1.OnFinger += new zkemkeeper._IZKEMEvents_OnFingerEventHandler(axczkem1_OnFinger);
axczkem1.OnKeyPress += new zkemkeeper._IZKEMEvents_OnKeyPressEventHandler(axczkem1_OnKeyPress);
axczkem1.OnConnected += new _IZKEMEvents_OnConnectedEventHandler(axCZKEM1_OnConnected);
axczkem1.OnVerify += new zkemkeeper._IZKEMEvents_OnVerifyEventHandler(axCZKEM1_OnVerify);
}
MessageBox.Show("Connection established!!!");
}
}
catch(Exception ex)
{
MessageBox.Show(ex.ToString());
}
}
以下是事件方法:
private void axCZKEM1_OnVerify(int UserID)
{
label2.Text = "Verify";
}
private void axCZKEM1_OnConnected()
{
label1.Text = "Connected";
}
private void axczkem1_OnKeyPress(int Key)
{
MessageBox.Show(Key.ToString());
}
private void axczkem1_OnFinger()
{
MessageBox.Show("Connection");
}
