Thread: Question about asynchronous communication

I would like to ask you, why did you cancel return from function? I call many times this function and I need returning value. It is not this function only for RDS label, but it also others. This code work fine, but I had the value only when I use System.print("stationOk is" + stationOk); but there was not any value in RDS.label, it was written undefienied. The result of my problem is that I need returning value from function. I hope...

'station' only gets assigned a value after the onConnect and onData callbacks are invoked, which is not immediately after the call to socket.connect(), so at the point where you are converting 'station' to an array, 'station' is not yet defined. After invoking "GetTuner()", the TCP socket will be connecting, but onConnect and onData will only get called later on, so GetTuner() cannot immediately return...

Very nice example. I believe that everyone who tried to experience callback functions will fall at least once in this kind of trap...
