RE: [DUG] OFF TOPIC

I think there are issues with the .NET mailing list – I haven’t seen your message come through which could explain the lack of replies.

 

From what I can tell, you are trying to change the text which is on one thread from the serialport control which probably has its own thread.

 

Do a google for update control from another thread.

Sorry to send this here....and I prob.should send to OffTopic, but just incase someone who is not on the offtopic list knows the answer I am sending here.

 

This is a .Net question that I asked lastnight 7pm but the email, infact no emails, has not comethru form the nz dotnet mailing list. If someone knows the answer, I would greatly appreciate the answer :-

 

Hi all.

I fired up VS2005 for the first time today...well first time to DO something....and I noticed the new SerialPort control.

This fitted in nicely because I want to read some data from the comport for the wee app I want to do.

 

Now I might be approching this the wrong way, but I dropped a serialport control onto my SmartDevice app....I am writting a PPC 2003 app. and set up the port settings etc, and on the "DataReceived" event I am doing :-

 

    TextBox1.Text = SerialPort1.ReadLine()

 

And THIS is where it throws an error.  Can someone please help?   The error is :-

 

System.NotSupportedException was unhandled
  Message="Control.Invoke must be used to interact with controls created on a separate thread."
  StackTrace:
    at Microsoft.AGL.Common.MISC.HandleAr()
    at System.Windows.Forms.Control.get_Text()

    at System.IO.Ports.SerialPort.CatchReceivedEvents()
    at EventLoopRunner.CallReceiveEvents()
    at WorkItem.doWork()
    at System.Threading.Timer.ring()

 

 

Thanks, Jeremy
