[twsocket] Simple FTP.Put Example
Is there a simple example of what is necessary to transmit a file using the FTP client? I am setting up the client with these properties: Up.UserName := Config.ReadString(Server,'Login','Anonymous'); Up.PassWord := Config.ReadString(Server,'Password','Anonymous'); Up.Port := Config.ReadString(Server,'Port','21'); Up.HostName := Server; Up.LocalFileName := SaveFolder+FileName; Up.HostFileName := FileName; Up.HostDirName := Config.ReadString(Server,'FTPFolder',''); Up.Timeout := 15; //seconds Up.Passive := True; But what is the methods I need to use to connect, send the file, and then disconnect? I will be doing this in synchronous mode. I see the Count parameter in FTP.OnProgress; does that represent the number of bytes sent, and do I need to initialize my progress par.maximum to the total file bytes of the local file?

[twsocket] Keeping a Responsive UI during THTTPCli Download
I have a simple program that downloads a large file using the HTTP Client. How would one keep the user interface responsive during a long asynchronous download? I have tried a number of things and finally ended up adding a timer with an Application.ProcessMessages in it. Is there a better way to keep the UI responsive for button clicks and such?

[twsocket] HttpCli Downloading Binary Files
I am having an issue with downloading by HttpCli. I am doing a really simple synchronous download of a binary file: HTTP.RcvdStream := TFileStream.Create(UpdateFileName,fmCreate); HTTP.URL := RemoteFileName; Application.ProcessMessages; HTTP.Get; TFileStream(Http.RcvdStream).Free; The file appears to be retrieved fine, and the resultant file size matches the one on the web, but it is an executable file and does not run afterward. So I am assuming it is being corrupted in some way. Is there a special mode/property for downloading binary files? I did not see any mention of it in the FAQ. I am converting a small indy application that used that HTTP component into ICS. I prefer to retrieve the web file by HTTP, but I can convert to ICS FTP is absolutely necessary.

[twsocket] Confirming an Abort in THttpCli
I have a multi-threaded application that uses a dynamically created THttpCli synchronously. I know that ICS is normally used asynchronously, but I could not determine a good way to handle that with all the dynamically created threads I have to use for database access anyway. When I want to terminate the thread normally or when I force it to terminate I call the THttpCli.Abort method. How can I insure that the THttpCli component is indeed aborted before freeing it and ending the thread? Right now I do: HTTP.Abort; while HTTP.StatehttpReady do Sleep(10); Is this incorrect, unecessary or adequate? I was getting some ICS errors when freeing the thread which may have been related to freeing the THttpCli or the underlying receive stream.

Re: [twsocket] Confirming an Abort in THttpCli
I think my problems may have been with the receive stream being freed before the THttpCli was aborted. Kind of like removing the road before telling your car to stop.

[twsocket] Retrieving and Forwarding Emails / HttpCli in v6
I would like to retrieve emails from a pop3 mailbox and forward them using smtp. I haven't used ICS for emails yet and wanted to see what the process would be. I made a test program with Indy that seemed to work and I posted a message to the Borland groups to make sure there was no problem with my simple logic. But I prefer to learn and use ICS methods instead. Here is what I want to do (synchronously): Retrieve a message from a POP3 mailbox change the recipient Send it using SMTP (synchronous) change the recipient Send it using SMTP ... for a number of recipients. What I need to know is will the message remain static (no changes to the multi-parts or attachments) for the entire process, other than my changes to recipients? I can look through the examples to see how to do this. I just need to be sure it will work before I take the time to research. Second question: I didn't see an HttpCli component in v6. I had considered installing it in BDS2006 for new projects, but that is a component I use a bunch. Is it missing, or should I use version 5 HttpCli with v6 or what? Is it named differently? Thanks for ICS. I'll send my postcard next week. :-) -- -Johnnie Norsworthy -- 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

The best way to do that is not to modify the component but derive a new one and add the behaviour you like. That's what I am going to do. It's just a handy shortcut for my applications. When you derive a component from an installed component do you have to create packages for design-time installation?

Re: [twsocket] About HTTP client V6 changes to support .NET
I am a newcomer to using ICS and have been very pleased with it so far. I prefer the non-blocking functions to anything I have seen in Indy, and I prefer the reduced number of components. I originally used Argosoft Internet Mail Suite before converting to Indy a couple of years ago. As far as .NET goes, I have no desire to compile the same source for multiple platforms. If ICS.NET is just similar to the Win32 library it would work for me to have a starting point. I would be using it with C# or Chrome, and certainly never VCL.NET. If VCL.NET is a requirement for ICS.NET, then I'll have to look into using another library or API when I create new .NET applications. Sidenote: My only wish for ICS is that the support from you and peer to peer was using regular newsgroups and not a mailing list.

Can you point the exact source code ? It is likely that your line numbers
doesn't match my line numbers. Show the offending line and a few before and
after so that we can locate exactly which istruction trigger the range
error.
In my source code, line 525 is:
OutputDebugString(PChar('Dispose ' + ClassName + ' ThreadID=' +
IntToStr(GetCurrentThreadId)));
It is possible that GetCurrentThreadId return an unsigned integer which
could not fit into an integer required for IntToStr (an integer in the range
2G to 4G). You may simply remove that line since it is for debugging
purpose, or fix it like this:
Thanks for responding..
This is the same line I have. The problem is that same code is all
over the place in the source. Is there another version of the source
without those debug statements or with conditional compilation
directives?
I need the code for the UDP packet sending as bullet-proof as
possible. Would you recommend programming it in something less
powerful than ICS - possibly the standard Delphi sockets? I can't use
Indy as it also cause some obscure error and I don't care to
inconvenience the Indy people anymore. I am running the server here
on on eo fmy machines with ICS code with no problems.
The machine the error is happening on is a Windows 98SE machine and so
far, it is just that one computer.

[twsocket] Converting from Indy - UDP Send - DNS caching
I am converting a small remote logging project from Indy to ICS that
sends UDP packets. Following the example in UDPSend1.pas, I do the
following when I wish to send my string:
WSocket.Proto := 'udp';
WSocket.Addr := 'mydomain.com';
WSocket.Port := '12007';
WSocket.Connect;
WSocket.SendStr('mystring');
in the WSocket.DataSent() event:
WSocket.Close;
What type of error conditions/exceptions might occur in the sending
code that I need to watch for? Is there ever a situation when .Connect
would fail due to an existing connection if sending a few packets in a
short span?
Do I need to add #13 #10 to strings before sending?
Can I cache the domain lookup after sending the first packet to speed
up the send process or is it helpful? If so, in what event do I grab
the looked up IP Address and from what property?
Thanks! I am looking forward to using ICS.
