Before to read using "AThread->Connection->Socket->Recv(ptr,len)" with ptr a pointer to a buffer and len the number of bytes to read from the connection. How can I know exactly the bytes that has been received in the socket ? I would like to pass the good value in "len" and adjust the buffer size of the receipt buffer Is a method like ReceiveLength() exist with TidTcpServer? Thanks for the help !

TCP is a byte stream. If you want to know the size of a particular buffer within that stream, then you should be sending the buffer size before then sending the buffer data. Indy is a blocking library. If you tell it to read xxx number of bytes, then it waits until at least xxx number of bytes are available before returning them. Quote: How can I know exactly the bytes that has been received in the socket ? What you are asking for applies primarily to asynchronous sockets, not blocking sockets. That is not the case with Indy. You tell it how much to read, and it returns that much back to you, internally handling all of the waiting and gathering of packet pieces for you. If that does not work for your situation, then your only option is to use CurrentReadBuffer(), which returns a String of all available bytes. Or alternatively call ReadFromStack() and then manually pull the available bytes from the InputBuffer property. Quote: Is a method like ReceiveLength() exist with TidTcpServer?
