Hello Anton,
*embarrassed* how these two statements combine?
Why several Receives should cause troubles?
it is by design, only 1 receive call in the event.
And another question. Is TWSocket.RcvdCount value reliable, i.e. if
it = 0, then there is really no data in the socket?

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,
Hello ibrahim,

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.

Hello Tobias,
In order to messure transmission speed I would write a small
test suite including client and server. The client would send
preallocated, constant data blocks in a loop and would use event
OnDataSent to send the next block. The server would simply through
away anything.

Hello John,
Normally this is no problem. I think with dropdown menu open there is no
problem also, because windows is pumping messages when a menu is open.
But depending on your applicaiton you can do the socket thing in a
separate thread. Other possibility is to run the communication in a
NT
be sent.
Given the 300ms for Send to return, is this to be expected?
If it is, then I will look to optimise elsewhere. But it just seems likely
that
something is a miss - wrong option setting maybe.
Regards,
Andy

My debug function to log the timestamps was the culprit.

Hello Dan,
As far as I know it shouldn't cause the TWSocket send call to take
longer since that is asynchronous
Correct, but I think he means the total time to send, not the time of
the function call.
