I have a windows application that sends and receives messages to/from a microprocessor using the serial port.
The application is working fine and does what is supposed to do. Now, I need to make some elaboration with the data I receive back from serial and I would like to access the variable "value" in SetText method. How can I access the content of that variable from another method or class? Thanks for helping.
delegate void SetTextCallback(string text);
private void SetText(string text)
{
if (this.txtOutput.InvokeRequired)
{
SetTextCallback d = new SetTextCallback(SetText);
this.BeginInvoke(d, new object[] { text });
}
else
{
txtOutput.AppendText(text);
}
// capture messages from serial port
if (txtOutput.Text.Length > 0)
{
MatchCollection mc = Regex.Matches(txtOutput.Text, @"(\+|-)?\d+");
if (mc.Count > 0)
{
long value = long.Parse(mc[mc.Count - 1].Value);
if (value > 1 && value < 1000)
{
textBox2.Text = value.ToString();
}
else if (value < 2000 && value > 1000)
{
value = value - 1000;
textBox3.Text = value.ToString();
}
}
}
}
private void serialPort1_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e)
{
try
{
SetText(serialPort1.ReadExisting());
}
catch (Exception ex)
{
SetText(ex.ToString());
}
}
