Exit Application and application stops and does not dispose

[nguyenxh]

Hello everyone,



I got a problem in C#: in my application there are 2 serial ports communication and when I click on a button to exit whole application, I expect that application would exit but my case is the application stops without disposing: this is my code for event of button:




Code Snippet

private
void Button_Exit_Application_Click(object sender, EventArgs e)

{

try


{

timer_Communication.Stop();

System.Threading.Thread.Sleep(10);

if (comport.IsOpen)

{

comport.DiscardInBuffer();

comport.DiscardOutBuffer();

comport.Close();

comport.Dispose();

}

if (readerPort.IsOpen)

{

readerPort.DiscardInBuffer();

readerPort.DiscardOutBuffer();

readerPort.Close();

readerPort.Dispose();

}

runApplication.Close();

Application.Exit();

}

catch (Exception ex)

{

MessageBox.Show("Bug 019\n" + ex.Message);

}

}













I event try to stop port communication before closing the application but the problem still occurs. Could anyone know any solution, please help me?



Thank you very much,



Regards,



Joesy
