[twsocket] Aborting transfers without AbortXfer?
What is the best and safest way to abort a transfer without closing the connection? I've tried the AbortXfer command but that doesn't work because the ABOR command is not available on the server I'm using. /Daniel -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
[twsocket] THttpSrv slight modification to function ExtractURLEncodedValue
Hi!
In one of my html forms I had to use html element select multiple
name=..., so when the user selects multiple items, we got a datastream
like this:
var1=value1var1=value2var1=value3... etc.
Original function returned only the first value of var1. I know the
remark states that it retrieves only a single value, but since I did not
found an other function retrieving multiple values like that, I took
some guts, and made some modification to it.
Just in case someone faces the same problem, here is the modified code.
In case of multiple values, they are separated by CRLFs, so the result
can be loaded to a TString descendent's Text property for example .
Peter
function ExtractURLEncodedValue(
Msg : PChar;{ URL Encoded stream }
Name : String; { Variable name to look for }
var Value : String) { Where to put variable value}
: Boolean;{ Found or not found that's the question }
var
NameLen : Integer;
FoundLen : Integer; {tps}
Ch : Char;
P, Q : PChar;
begin
Result := FALSE;
Value := '';
if Msg = nil then { Empty source }
Exit;
NameLen := Length(Name);
P := Msg;
while P^ #0 do begin
Q := P;
while (P^ #0) and (P^ '=') do
Inc(P);
FoundLen := P - Q; {tps}
if P^ = '=' then
Inc(P);
if (StrLIComp(Q, @Name[1], NameLen) = 0) and
(NameLen = FoundLen) then begin {tps}
{*** Multiple Values ***}
If Value ''
Then Value := Value + #13#10; // separate values by CrLf
{**}
while (P^ #0) and (P^ '') do begin
Ch := P^;
if Ch = '%' then begin
Ch := chr(htoi2(P + 1));
Inc(P, 2);
end
else if Ch = '+' then
Ch := ' ';
Value := Value + Ch;
Inc(P);
end;
Result := TRUE;
// break; {*** Commented *** We are looking for more
Name-s}
end;
while (P^ #0) and (P^ '') do
Inc(P);
if P^ = '' then
Inc(P);
end;
end;

Re: [twsocket] Aborting transfers without AbortXfer?
What is the best and safest way to abort a transfer without closing the connection? Are you talking about FTP client component ? I've tried the AbortXfer command but that doesn't work because the ABOR command is not available on the server I'm using. Then you have to close the connection... What's the problem ?

No that is not an option for us. We want to prevent the authentication process when the domain entered by the client is not in our list of permitted domains.

Re: [twsocket] bytes lost with PUT FTP
Possibly a transfer mode error. Make sure you are transferring in binary mode. Note: I think you need to set a property to make the client component not modify end of lines AND send the binary command to the server.

[twsocket] Ping stopped working - in fact kills the program first!
Hi I have been making some program changes in the same module as a Ping procedure. On creating the module I now get an error:- Exception EReadError in ... Error reading Ping.OnDnsLookupDone: Invalid property value. In the .dfm module the Ping looks like this :- object Ping: TPing Size = 56 Timeout = 4000 TTL = 64 Flags = 0 OnDnsLookupDone = PingDnsLookupDone Left = 188 Top = 82 end The error goes away if I disconnect the event. I'm not aware of making any change in the Ping area - but I have obviously upset something. I suspect that this has nothing at all to do with ICS - but have no idea what is wrong. Any ideas?
