[flexcoders] #2031: Socket Error
I'm trying to send a simple string to a Printer Server on our network.
The text is a language called ZPL which is going to our little print
server box that has a Zebra Label printer on its parallel port.
Here's my test app:
?xml version=1.0 encoding=utf-8?
mx:WindowedApplication xmlns:mx=http://www.adobe.com/2006/mxml;
layout=absolute
mx:Script
![CDATA[
import mx.controls.Alert;
private function onPrintZpl():void
{
var sData:String = ^XA^FWR^CI13 +
^LHLabelTop,LabelLeft +

try
{
var socket:Socket = new Socket();
//socket.addEventListener(IOErrorEvent.IO_ERROR,
onIOError);
socket.connect(10.44.180.120, 9100);
socket.writeUTF(sData);
socket.flush();
socket.close();
}
catch(error:Error)
{
Alert.show(error.message);
}
}
private function onIOError(event:IOErrorEvent):void
{
}
]]
/mx:Script
mx:VBox width=100% label=Printing
mx:Button label=ZPL Print click=onPrintZpl()/
/mx:VBox
/mx:WindowedApplication
With the app as it stands, I can hit the ZPL Print button, the label
is printed, but then the app throws this error:
[SWF] SocketTest.swf - 902,761 bytes after decompression
Error #2044: Unhandled IOErrorEvent:. text=Error #2031: Socket Error.
at
SocketTest/onPrintZpl()[C:\Development\Monarch\Test\SocketTest\src\Socke\
tTest.mxml:28]
at
SocketTest/___SocketTest_Button1_click()[C:\Development\Monarch\Test\Soc\
ketTest\src\SocketTest.mxml:58]
If I uncomment the call to addEventListener() for IOErrorEvent.IO_ERROR,
the app runs without any errors, but the label isn't printed.
Any comments/help gratefully received.
Thanks,
Ed.
RE: [flexcoders] #2031: Socket Error
When you hit a 2031 error, to troubleshoot further I'd recommend running
Wireshark (formerly, Ethereal) to capture the TCP packets sent/received when
you run your test.
