Thank you so much Wilfred for your quick answer. One question:
I do that int length = FWSocket->RcvdCount; if(length == 0) return; char *str = new char[length + 1]; FWSocket->Receive(str, length); str[length] = 0; you wrote that sometimes FWSocket->RcvdCount is 0. What should I do to receive data? I prefer to read char array because I have chars with value < 0x20 Thank you Regards Ing. Alessandro Miorelli Software Engineer Microgate S.r.l.

Just receive the part of data that is received and exit. When next chunck of data come in the OnDataAvailable will be fired again. TCP protocol does not respect data boundaries.
