Re: [twsocket] Should next ICS version support anything before Delphi XE ?
Hi, I have some old projects on D2006 that get tweaked from time to time. Using V6? No major new development. Anything new is now using XE. ...Andy On 28/03/2012 19:59, François Piette wrote: Hi !

Re: [twsocket] Help with stalling ftp client
Hi, Some additional information after hooking up wireshark. I have attached a csv of the capture. What it shows me is that I get the 150 from the server, I then send an ACK, but I don't send the FTP-DATA. Then of course, I don't see the request done event, because I have not sent the data. For the ACK to go out after the 150 response I am assuming that the ftp client has seen the response, and sent the ack. Or am I mistaken? Is this a lower level interaction? (in winsock somewhere) Why would I not send the data - is my question really? I don't have any Application.ProcessMessages loops in my application - apart from a start up splash screen, and an application shut down loop waiting for a thread to close down. Neither are active when my ftp stalls. The thread I create has nothing (intentionally) to do with the ftp client. It monitors a usb serial port, downloads serial data and creates files on the file system. This thread is not downloading serial data and creating files, as there is no device connected. I do now detect the stall with a timer, but don't currently restart - just display a message so that the user can retry. I am logging all RequestDone events, and nothing is reported when I stall. I have attached the csv that shows the last good transfer, then the stall. If an alternative format is preferred, just ask. Ideas?

Hi, I have been using the ftp client component for a couple of years now without a hitch. Until recently. The version is 7.09. I have in the main thread a timer that runs a state machine to control logging in and sending of the files. But recently, the state machine stalls and times out.

This is as a result of calling PutAsync on the component.

[twsocket] Connect to FTP proxy not in transparent mode - prompt for account
Hi, If the ftp proxy is prompting for account, how should I connect? Should I set the account string property and call ConnectAsync, or should I call ConnectAsync then AcctAsync, or just call AcctAsync? I'm struggling to test as I have no access to the proxy in question, otherwise I'd just use trial and error. Googling for a proxy to download and install is coming up with lots that use transparent mode, but that's not what I need. Anyone used a free ftp proxy that can use authentication?

Your best bet, as your user wants to use a specific proxy, is to ask them to provide you with an install of such a proxy (as a loan item, that you will return to them when you're done developing and testing) with the account setup instructions, so you can make your own test system, allowing you to freely test your code, without anoying any other system users/owners or whoever. If the proxy is prompting you for an account, you have connected! What I know, I just don't know how to progress with the account info.

Re: [twsocket] FTP through proxy not in transparent mode
Francois, Usually non transparent FTP proxies work by connecting to the proxy itself and then when asked username, entering the real user name followed by and @ and the remote server name. Sometimes the @ character is replaced by a # character. I was under the impression that this was how transparent proxies work, based on comments in the source: How to use a Proxy or Firewall ? First of all, not all proxies or firewalls are the same. So have a look at product documentation. However, most products support a transparent proxy which doesn't require any special programming: 1) Instead of connection to a remote FTP server, you connect to the proxy 2) User name is replaced by user name, followed by '@' sign then followed by target remote FTP server host name. 3) Password is usual remote FTP server password. 4) Most require using Passive mode. Example: You want to connect to ftp.borland.com, using anonymous connection, company firewall/proxy is running on host named proxyserver. FtpCli1.HostName := 'proxyserver'; FtpCli1.UserName := 'anonym...@ftp.borland.com'; FtpCli1.Password := 'your.em...@company'; FtpCli1.Passive := TRUE; Or am I getting muddled here? ...Andy -- francois.pie...@overbyte.be The author of the freeware multi-tier middleware MidWare The author of the freeware Internet Component Suite (ICS) http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

[twsocket] OT Delphi ADO question
Sorry for the OT guys, but I'm not getting any response on forums.codegear.com, and since you guys know your stuff, I'm hoping for some tips. I am using an ADO stored proc to call a stored proc on a MSSQL server. One of the parameters in the stored proc on the server is a Decimal(28,20) but delphi detects this in the parameters list and sets it to ftBCD, precision 28, scale of 20. Now, trying to insert a number of 53.4167098 ends up in the database as 53.4167, and the profiler captures this as well. So, something happening at the delphi end. I am using Turbo 2006. I have manually changed the parameter field type to ftFloat in the GUI, and also in code just before the call is made to the assignment of the value. But still the truncation. Any ideas guys?

Re: [twsocket] OT Delphi ADO question
Angus, Thanks for the response. Yes I'm using the stored proc component. No data aware controls. So, you solution would be something like creating a string: exec sp_InsertVehicleData;1 '2009/01/17 15:48:12',1,'0358104000636686','0F611B8C',17,$53.5161,$-2.2367,0,$15475. 5996,$0.,$0.,0,0,'S',0,0,0,0,0,0,0,0,'',$-2.2367,$53.5161,$65535.000 0,0x010358104000636686FF447800344015FF2A0F611B8C11EAC5738C79105642C0260F C8B904C0260FC07910564200FF7F47900105,60,1,'447800344015' which is the command captured with the profiler.

It sounds like you are using the stored procedure component, and some data conversion is going wrong. Unless you are using data aware controls or something, you can build the command and parameter list for the stored procedure as a simple widestring and use the EXECUTE method in the connection to run it. You can get a result set and read it as string numerics, to get whatever precision you need. ADO only deals in ASCII, not numerics, all conversions to internal SQL data types take place in ADO or SQL itself, not Delphi.

You're original error could be in those strings. You might be better passing strange numbers as VARCHAR and converting them to numerics in the stored procedure itself, assuming you can mess with it.

Re: [twsocket] processmessages or messagepump
Francois, and Arno, while not terminated do begin WSocket.MessagePump; // check if I need to do something sleep(100); end; // close it all down Or am I missing the point in the use of the message pump? Yes, you miss something. The code you've done will be very slow at processing events because of the sleep. And it you remove the sleep, it will use all CPU. OK. The solution is simple: you need to use a real message loop. Easy: just call MessageLoop which all TWSocket instances have. To terminate the message loop, you can post a WM_QUIT message when you detect your thread has terminated. If I do: while not terminated do begin WSocket.MessageLoop; // check if I need to do something end; // close it all down Then my understanding from what you have said is that I only get to the // check if I need to do something when a quit is posted. I am running a finite state machine in the execute loop, which marshalls responses, checks timeouts etc. If I don't exit the message loop, I can't do this. Really sorry if I am missing the point on this. Long hours, fried brain.

[twsocket] OnDataSent event and related questions
Hi, I am currently using the OnDataSent event of TWSocket to signal my state machine to move on. This is working mostly, however, sometimes, the event does not happen. Now, at the far side, the server being connected to closes the connection when it has it's data, so I am thinking that this close will sometimes mask the OnDataSent. It is happening about 1 packet in 40, each packet being 60 bytes. Some of the servers will not close the connection after a packet, and some do, some servers send a acknowledge packet back, so I need a reliable method of testing that the data has gone, before I can proceed in the state machine. Is hooking the disconnect event a valid approach if the OnDataSent event does not fire?

Arno, Arno Garrels wrote: info2004 wrote: When the server closes the connection OnSessionClosed triggers. In order to check whether component's internal send buffer is empty you have property BufferedByteCount.

I think that we are at cross purposes here. The OnDataSent event looks like it does not fire (sometimes) if the far end (server) closes the connection. Is this true? The server gets the data, then closes the connection, and at my sending end if I solely wait for OnDataSent, sometimes it does not happen, and I time out.

[twsocket] [OT] ADOQuery async operation
Hi, I have posted to newsgroups.borland.com, but so far no joy. I am using some ICS components in my project though;) The problem I have is getting the ADO stuff to work asynchronously. I am using a TADOQuery and have set ExecuteOptions to [eoAsyncExecute, eoAsyncFetch], and have set ADOQuery.OnFetchComplete := MyHandler. I have two ADOQueries, one doing a 'SELECT *', and another doing an 'UPDATE'. The select query fires it's OnFetchComplete, no problem. The update query does not seem to fire anything. All of this happens in a thread, and the ADOConnection, ADOQuery are created in the .Execute of the thread before my while (not Terminted) loop. All works as expected if I use sync calls, but I want to let other threads in whilst waiting for the results. So, working on the assumption I have missed something, does anyone know of any articles on using ADOQuery asynchronously? Google is not proving to be of help so far. Any help appreciated.

[twsocket] Which threaded server sample to use
Hi, I am using V6 beta with Turbo Delphi 2006. Can someone tell me which threaded server demo I should use as my base for an app please. MtSrv points you to ThrdSrv. ThrdSrv has ThrdSrv, V2 and V3. V2 works but does not like WM_TRIGGER_EXCEPTION. V3 complains at TWSocketThrdServer - not found.

AFAIK none of the multi-threading demos is converted to V6 yet. ThrdSrv uses a design one thread per (client) connection, that's the easiest way to implement multi-threading with ICS. Another design was multiple (client) connections per thread. That's much harder to code and only suggested when scalability is required that is when plenty of concurrent clients (beyond thousand) need to be served on multi-processor servers. Anyway tell us why do you think you need multiple threads for network communication. The server will be accepting connections from mobile GPRS units. When they connect, they will be updating the firmware (128K bytes), and also sending configuration commands that will be gleaned from an MS SQL server. I am quite happy that ICS does not need to be threaded - my first server using ICS uses just the main thread quite happily. But having these lengthy/blocking aspects to this server is pushing me down the threaded route. As for whether ADO is thread safe, there are lots of conflicting opinions on the borland news server borland.public.delphi.database.ado.

[twsocket] TWSocket not connecting for me
Hi, I have a problem with TWSocket.State staying as wsConnecting after I try and connect. I am using a thread to execute an SQL query. For each result from this query, I connect to a remote server using the TWSocket, and send some data. That's the plan. In the Thread.Execute procedure, I have created the TWSocket, then I run through a state machine to query the database, make the connection etc. Does anyone know why .State would stay at wsConnecting? I can connect to the server manually using telnet, and I don't have any problems providing additional info. Just didn't want to overload the email at this point.

Re: [twsocket] TWSocket not connecting for me
SZ, I had a look through the list and saw the ref's to get and peek etc. I did a grep on the source and decided to use TWSocket.ProcessMessages in my Thread.Execute loop. This seemed to work. The socket connects and I send my data.Are there going to be any pitfalls in doing this? Thanks for the help. regards, Andy Fastream Technologies wrote: Search for MessagePump/GetMessage API function in this list's archieve to learn more. The TWSocket also contains a messagepump() function to see. If you use sync methods, then the message pump is implicitly called until needed. The bad thing is that there is a single action done in the thread. If you want parallel execution in the same thread, use async/events plus GetMessage of your own.

It multitask automatically WITHOUT using threads. Programming is then much easier... To date, I have used the components without additional threads. This is my first experience using threads. I had to do this because the SQL stuff I use (ADO) is blocking. If the SQL server is busy, or down, you get very large waits in your program. So I have moved the SQL stuff into it's own thread.
