该程序正常运行。当出现提示并点击“无效的RFID”时,弹出无效的RFID消息,我可以再次扫描。但是,如果RFID被接受,我希望提示自动关闭。在此程序中,提示不是自动关闭。我必须添加什么才能使提示自动关闭?
private void serialPort1_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
string ramses = serialPort1.ReadLine();
SetRFIDText(ramses);
}
private string dotRFID = "";
private bool shouldClose = false;
protected void SetRFIDText(string input)
{
this.Invoke(new Function(delegate()
{
string Hexed = new LasalleRFIDComputerRentals.BLL.DAL.Utils().HexIt(input);
dotRFID = Hexed.Trim();
txtRFID.Text = Hexed.Trim();
if (txtRFID.Text.Trim() == "")
{
MessageBox.Show(this, "Please provide the member's RFID.", "Save Member Information", MessageBoxButtons.OK);
txtRFID.Focus();
return;
}
CustomerInfo customer = new Customer().GetCustomerByRFID(txtRFID.Text);
if (customer.CustomerID <= 0)
{
MessageBox.Show(this, "Incorrect RFID.", "Validation", MessageBoxButtons.OK);
return;
}
else
{
txtRFID.Text = "";
if (_parentForm == "StandBy")
{
Utils.CurrentCustomer.CustomerInfo = customer;
frmStandBy form = (frmStandBy)this.Owner;
form.xResult = "OK";
this.Close();
}
}
}));
}
我尝试在底部使用this.Close();
(form.xResult = "OK";
下),但最终会挂起。救命啊!
答案 0 :(得分:0)
嗯,我能够通过将This.Close();
更改为This.Hide();
