Exit Application and application stops and does not dispose

[Guest 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,
