Hi Edward,
Seeing as you raised this issue, and I have been experiencing the same
thing, I thought I'd dedicate the day to trying to understand what is
happening, and the good news is that I've managed to solve my problems, and
gained a valuable understanding of the problem. Here's the thing.
Use TWSocket component to connect to the server using same parameters
(127.0.0.1/TCP/1099). Then send the data in the same format, then grab the
response (using OnDataAvailable event and Receive method) then gracefully
close the socket (Shutdown).

Hi,
I have two UDP listener sockets in a worker thread (I use a thread because is a
DLL). When I receive any data in the OnDataAvailable, ReceiveFrom method call
return -1 and OnDataAvailable is triggered in a infinite loop. The same code
with Receive method works fine.
What is wrong? Could be
Hello Erich,
I see in your other mail that your problem is solved. So here I try to
answer to your additional questions.
What influences how much buffer RAM is used by each socket.
It is the socket itself and also the data. A socket takes around 4 KB.
Overlapped IO takes also pages of 4 KB but
Hello Wilfried,
thank you for your help.
I've changed my code but the problem persists. Internally RecvFrom is
Result := DoRecvFrom(FHSocket, Buffer^, BufferSize, 0, From, FromLen);
if Result 0 then
FLastError := WSocket_Synchronized_WSAGetLastError
else
FReadCount
Hello Lorenzo,
I see one bug. Possible that's the reason:
FromIPLen = sizeof(FromIP); // Add this !!
rec = server-ReceiveFrom(block, sizeof(block), FromIP, FromIPLen);
