Main page -> ICS component reference -> TWSocket -> ReceiveStr
Definition
function ReceiveStr: string;
Description
ReceiveStr is used (mainly in OnDataAvailable if the component is set to use LineMode. It receives the next complete line which has been sent to the attached IP/port. ReceiveStr returns the whole line sent, including the delimiter characters set via LineEnd.
Example
procedure TMySocket.MyOnDataAvailable(Sender: TObject; ErrCode: Word);
var s :String; // received packet
begin
if ErrCode <> 0 then
begin
exit;
end;
s:=ReceiveStr;
end;
Best practices
- always set LineLimit
