Uncaught Error When Closing Daqfactory Down.

Recommended Posts

I'm using a device with null protocol to communicate over ethernet to a server.

Everything works fine until I need to close DaqFactory down then every time I get a "C1136" Timeout error - Uncaught Error in sequence yet I have a Try/catch construct around the statement that fails:

 

   while(1)
      try
         ReceiveData = device.StraqTCP.ReadUntil(chr(10))         
           Lots of other code.....

      catch("C1136")
         ?"Error C1136 caught in SocketRcv"
      endcatch
      catch()
         ?"Error caught in SocketRcv"
         System.ErrorMessage(strLastError)
      endcatch
            
   endwhile

I guess I have to close this device and the ReadUntil before I close Daqfactory - but How do I do that? I have a sequence called "OnShutdown" that I use to tidy things up when the app closes and that works ok but I haven't figured out how to close the device down gracefully.

 

 

I've tried 

 
   device.StraqTCP.Timeout= 0
   device.StraqTCP.Address = ""
   device.StraqTCP.port = 0
   device.StraqTCP.Timeout= 10
 
but nothing seems to stop the device. 
 
Problem is that onsite (where I run Daqfactory only in RunTime mode) getting a dialog saying "Daqfactory has encountered a problem" ... "Please tell Microsoft...." does not install confidence in the customer.
On my development system running in development mode I get "C1136 Timeout: SocketRcv Line 13 - Uncaught error in sequence SocketRcv" shortly after whenever I switch to safe mode.
 
 
How do I shut the device down gracefully?
 
Rod.

I'm not sure the two are related, but to shut down gracefully, either end the sequence hard using endseq (which isn't too graceful), or add a flag to your while() and set the flag false when you want to quit, then wait for the sequence to quit.
