Hi François
Merry Christmas to you, your family and all the ones you love.
________________________________________________________________________
Thank you for your answer about the range check error that occurs
in your unit OverbyteIcsWSocket.pas (version 8.06), function
TCustomWSocket.Send
at line PostMessage(Handle, FMsg_WM_ASYNCSELECT, FHSocket,
IcsMakeLong(FD_WRITE, 0)); [resaon FHSocket=-1].
I totally agree with you, every range check error is something to avoid ;-).
(As this one happens in your code, I thought you might be interested in.)
For me it works with adding
"if FHSocket <> -1 then"
PostMessage...
to your code.
________________________________________________________________________
You might as well type cast (your answer, dec 22 2013) FHSocket -> WParam(
FHSocket ). Then no range check error occurs. But then you just send a
FMsg_WM_ASYNCSELECT which will be handled in your
procedure TCustomWSocket.WMASyncSelect(var msg: TMessage);
by
if msg.wParam <> WPARAM(FHSocket) then
Exit;
________________________________________________________________________
I prefer not to send PostMessage to the message queue.
Thank you a lot for ICS.
Best regards
Michael

Subject: Re: [twsocket] unit OverbyteIcsWSocket.pas, version 8.06 -
range check error
Message-ID: <00e201ceff2e$43e6a2d0$cbb3e870$@skynet.be>
Content-Type: text/plain; charset="iso-8859-1"
When I send data using the send method, XE5 sometimes reports a
RangeCheckError
in function TCustomWSocket.Send(Data : TWSocketData; Len : Integer) :
Integer;
at line
PostMessage(Handle,
FMsg_WM_ASYNCSELECT,
FHSocket,
IcsMakeLong(FD_WRITE, 0));
Reason: FHSocket is -1
Maybe it's by design (?). If you need further infos then please let me
know.
FHSocket is -1 when the socket has been closed. This is not an issue but
to
avoid the error, FHSocket should be cast to WParam like this:
PostMessage(Handle,
FMsg_WM_ASYNCSELECT,
WParam(FHSocket),
IcsMakeLong(FD_WRITE, 0));
Let me know if it works for you.
