Hello Anton,
Don't worry. You don't have to do anything on the 'would block' winsock
error. TWSocket deals with it.
when OnDataAvailable fires, just try to receive all data. When Receive
return 0 or -1 then just exit the event handler.
-1 is error (don't worry), and 0 is if the peer has closed.
Hello Martin,
Here is a small example:
procedure TFoo.FUDPDataAvailable(Sender: TObject; Error: word);
var
Buffer: array [0..1023] of char;
Len: integer;
Src: TSockAddrIn;
SrcLen: integer;
begin
SrcLen := SizeOf(Src);
Len := TWSocket(Sender).ReceiveFrom(@Buffer, SizeOf(Buffer),

When the server close then the local connection is closed also. Probably
all data is not transmitted to the client at this moment. Try to find
this place in the code and replace Close or CloseDelayed with
Shutdown(1). That's probably the reason.

If you are behind a router then you have to switch to passive mode. This
means that the FTP server will listen on another port for the data

the client will listen on another port but blocked by the router.
