Last Modified: 2012-05-05
Developing apps for WM6, frequently I have problems with serial port that hangs when I close it. I've found on a forum this code but I don't be able to convert in VB 2005.
Can somebody help me ?
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
if (serialPort1.IsOpen)
e.Cancel = true; //cancel the fom closing
Thread CloseDown = new Thread(new ThreadStart(CloseSerialOnExit)); //close port in new thread to avoid hang
CloseDown.Start(); //close port in new thread to avoid hang
private void CloseSerialOnExit()
serialPort1.Close(); //close the serial port
catch (Exception ex)
MessageBox.Show(ex.Message); //catch any serial port closing error messages
this.Invoke(new EventHandler(NowClose)); //now close back in the main thread
private void NowClose(object sender, EventArgs e)
this.Close(); //now close the form
