Hello, I think I found a bug in Java and/or ICS: I guess while testing you did not set the auth mode to daBoth. Set it and try with the helloworld applet! Java sends a HEAD request which is well authenticated and then sends a GET with missing info and it stalls!!! As a workaround, I set damode

Re: [twsocket] udp multicast multiple packages - TWSocket bug?

Hello, I did a quick look. It seems you start (or resume one from pool) a thread and give the received data to it. Probably you give data again to a thread that is still busy with the previous data. You have to check for this somewhere because you tell about corrupted data with many threads.

Re: [twsocket] WinSock error 10035 with TWSocketServer

Hello Bevan, It is normal that you receive an empty string once a while. Just exit the OnDataAvailable event in that case. When data is really ready to receive OnDataAvailable will fire again. About the 10035 yo dont have to worry. This is internally handled by TWSocket. --- Rgds, Wilfried

Hi Michael, Sorry, I sent my previous reply directly to you instead of to the list. thanks for the hint, I already looked into the code and - by the way - I find it very well structured. However, one question is left. There´s always spoken about using async components, but in my special case

Hi Wilfried, It is normal that you receive an empty string once a while. Just exit the OnDataAvailable event in that case. When data is really ready to receive OnDataAvailable will fire again. I see your point - the other day I got the same result over and over again, today the same code
