[RESOLVED] [2005] How to use the Timer or Stopwatch Class to timeout in 30 seconds

[IkeConn]

Hello,

Nothing I have found on the Stopwatch Class shows how to watch for X seconds elapsed time in a piece of code. It seems to be generally used for performance measurements.

What I'm doing is grabbing data from a serial port, which works, but it can't handle a connection that doesn't send data so I want to time out the serial port based on nothing happening for say 30 seconds.

What I need is code that will do something like this pseudo-code:


Do Until SerialPort.BytesToRead >= XXXX or timeOut = 1

start stopwatch
when 30 seconds elapses set variable timeOut = 1 'to be used in Do test
stop stopwatch

<other stuff here/>

Loop


Thanks,

Ike
