[twsocket] ftp to Table
Hi I like to use ics ftp to transfer the contents direct to a table and not save it first to disk Could this be possible? Now I'm saving to contents to a file on disk, then read the file and save the contents to the table, wich is time comsuming. Now: 1.open the ftp 2. read one or more files from ftp 3. save one or more files to disk 4. read file from disk and save to table 5. then close ftp I like to 1.open the ftp 2. read file from ftp and save to table 3. then close ftp If not possible with ftp, can this be done with socket to access an ftp server Would be great for an example Thanks in advance for any response Werner -- 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
Re: [twsocket] ftp to Table

Could this be possible?
Now I'm saving to contents to a file on disk, then read the file and
save the contents to the
table, wich is time comsuming.
Now:
1.open the ftp
2. read one or more files from ftp
3. save one or more files to disk
4. read file from disk and save to table
5. then close ftp
I like to
1.open the ftp
2. read file from ftp and save to table
3. then close ftp
If not possible with ftp, can this be done with socket to access an ftp
server
Would be great for an example
Not sure I understand the problem. Do you mean you want to save a big file
located on a FTP to a
table locate in a database accessible from a client PC ? Do you mean you
want to avoid saving the
file to a local file first and save to the table on the fly.
On solution is to design a TSream derived class that when you write data
to it, data is written to
your table. FTP component will then be able to use it with his LocalStream
property.
I have a small file located on a FTP
I want to read this file, line per line, and save this data direct to a
local table.
So I don't need to save this file first to disk, and read it again.
I took a look at the localSteam property, and tried this example.
The ms.Size give a number, but I can't get the stream into data?
var
ms:TStringStream;
data:string;
begin
ms:=TStringStream.Create(data);
try
FtpClient1.HostName:= HostNameEdit.Text;
FtpClient1.Port := PortEdit.Text;
FtpClient1.UserName:= UserNameEdit.Text;
FtpClient1.PassWord:= PassWordEdit.Text;
FtpClient1.HostDirName := HostDirEdit.Text;
FtpClient1.HostFileName:= HostFileEdit.Text;
FtpClient1.LocalStream := ms;
FtpClient1.Binary := True;
FtpClient1.Receive;
DisplayMemo.lines.Add('Memorystream '+IntToSTr(ms.Size));
DisplayMemo.Lines.Add(data);
finally
ms.Free;
end;
end;

Re: [twsocket] ftp to Table
Thanks
ms.Seek(0,0);
DisplayMemo.Lines.Add(ms.DataString);
Works great. It looks like ms.Seek is quit important sometimes. In case of
using TMemoryStream its needed, TStringStream not all the time.
ms:=TStringStream.Create(data);
When using TStringStream.Create('') it's the same, seems like the var 'data'
has no meaning here.
Thanks for your help

[twsocket] Socket server overhead
Hi, I have an application that continueous (every 500ms) have contact with a machine by rs232. Main thread. I want to send some information by socket when an external program ask this. So this program must also listen as a server socket. My question: when a server socket is in listening mode, does it take a lot of resources ?, would it be best to put this in a thread with low priority?, but if I do this, will the communication with the rs232 not take all the attention, so the thread with low priority will not work. Any response on this would be great.

When a client connect you accept/dup the client to a data socket. Server stay listening. You can use a normal TWSocket as server and handle the creation of data sockets, but then you are just re-inventing TWSocketServer who does that for you. You can set MaxClients to 2 if needed. Note that I'm talking about TCP. If you use UDP then you can do listen / send / receive with only 1 socket. But ICP is reliable the other not. --- Rgds, Wilfried http://www.mestdagh.biz Saturday, October 8, 2005, 10:02, Werner wrote: Hi, Is it possible to have a socket connection from client to client ?

Re: [twsocket] Socket one to one
Thanks, I'll check this out At the server end just use a TWSocket instead of a TWSocketServer if you only need one client. Then it needs to listen: Socket.Listen; and when a connection comes in (SessionAvailable) you accept it: Socket.HSocket := Socket.Accept; Then the connection is established.

Thank, Thanks, I'll check the receive function An other Q. about TimeOut After connect to the server, I send a string 'SENDDATA' In OnDataAvailable, i check for incoming data, but when no data arives, then I want to close the connection. Now I'm using a separate timer to check this. Is there an other way to do this, so far I've red that after the connect, onDataAvailable will fired direct, but is this when also when no data comes in?

Then OnDataAvailable will only fire when thes character(s) are received and you have all your data at ones. If not it will arrive in many chunck, or datapackets can even be concatenatied. Thats nature of TCP. Now, I'm using CliSocket.ReceiveStr to recieve data and put this in a buffer until all data is read That is the right way to do if you dont have terminating characters. Better is to use Receive, then you save an extra copy to a string. --- Rgds, Wilfried [TeamICS] http://www.mestdagh.biz Wednesday, October 19, 2005, 10:18, Werner wrote: Hi, Does twSocket has a method to use streams I want to recieve some data in a TStringStream Now, I'm using CliSocket.ReceiveStr to recieve data and put this in a buffer until all data is read I wonder if I can read all data in one piece by using streams?

Re: [twsocket] Port number
Thank Wilfried, thats explains a lot. When the server listen to port 2500, and the socket port start increasing from 2000. Do I get in trouble when it comes finaly to port 2489,2499..2500 the same port where the server is listening, or is this handled automaticaly by the socket that the increasing port will never be the listening server port ? To explain more: my program get every 10 seconds an incoming client, get the command, then close again. And I see the port increasing fast, what about a limit ? can I reset the portnumber?, it's a black hole for me. The client has port 2000. When the client change his port to 2001, is there a way, when connecting to the server to retreive the clients actual port address?. I must know this port because I need to contact this client back on an other WSocket. Ofcourse it wil work fine if the client don't change his port number.

Re: [twsocket] Port number
On a second session, the server turns client, and client turns server: client(ComputerA) port 2000 - connect server(ComputerB) at port 2500.

[twsocket] TWSocket - send bytes - strange chars
Hi everyone,
I have a spooky situation.
I send a file.txt. This file contans some default chars as any file can have.
This file is sended with the proc below to a java application.
This java application will block reading until it has read all chars.
Now the problem is, that the java will get some stack errors, only when certain
chars are sended in this file.txt
( and i realy don't know wich chars, but a test, leaving some chars out of the
file, point in that direction, the size is not imported)
I know this looks more like a java problem, but maybe somebody has encountered
something simular.
So my question is : are their any chars or combination, that could be sensitive
? This question is as wierd then the problem I have :).
Thanks for any idees
Greetings
Werner
procedure TMainForm.SendFile(sCmd,sFile:string);
var Fs: TFileStream;
Buffer: array[0..1023] of byte;
iCount: Integer;
begin
Fs:=TFileStream.Create(sFile, fmOpenRead or fmShareDenyNone);
try
{ send size file }
CliSocket.SendStr(IntToStr(Fs.Size)+#13#10);
{ send file }
repeat
iCount:=Fs.Read(Buffer,sizeof(Buffer));
if iCount 0 then
CliSocket.Send(@Buffer,iCount);
until iCount = 0;
{ flush socket }
CliSocket.Flush;
finally
Fs.Free;
end;

Re: [twsocket] TWSocket - send bytes - strange chars
Thanks Wilfried to point me on this possibility, hoped this would be it.
I tried only sending bytes 31 and 127 but it remains the same.
Rgds,
Werner

Hello Werner,
I'm pretty sure this is a Java problem. Something to do with the 16 bit
char conversion. If you try text with char = 127 then do you have same
problem too ?
