[twsocket] Insert image into email body
Hello, I've a little problem when sending an e-mail with images. Ii'want create an e-mail with an image into the body of message, like thunderbird when you use menu insert - image. I've tried htmlsmtp.EmailImages.text with ContentType := smtpHtml, but when receive the message the image is an attachment. Anyone know how i can resolve this problem ?

Re: [twsocket] [HELP]FTPServer within a service...
Hello Guillaume, We have an implementation of ICS FTP server within a service however it has no service GUI as its GUI is made of another process that communicates with the engine through XML/HTTP. Take a look at http://www.fastream.net/netfileserver.htm and if you want to design something similar, I will be more than glad to answer your question(s).

i'm wondering about the way to implement a FTP server (with thread on GetProcessing) within a Windows Service ? Any windows GUI application can be run as a service, provided it never asks for any input from the user. I use a very simple real service that runs the windows program, and sends it a message telling it to exit when the service is stopped. If the message is lost, it terminates the program. This makes debugging very easy, since you can have as many, buttons, labels and memos in the application as you like.

Particularly when you use a Thread within the GetProcessing event and that you delay the DoSendData... In this later case, the message to the server socket (to send data : WM_FTPSRV_START_SEND) is sent but never received, unless you can trigger the log window's message pump wich then transmit it to the socket. But if meanwhile the client has disconnected, then there's an exception... i don't know if i'm clear enough :| !

Re: [twsocket] [HELP]FTPServer within a service...
Hello Guillaume, On my site you find a simple class to include in your GUI program so that the same EXE can run as normal GUI and also as NT service without any change. Advantage is that the service can make a tray icon when user log in, and if you click on it the service can popup his main form. Very easy for config and so :) With the ICS examples there is a lso a NT service demo. I think it is for WTSocketServer. --- Rgds, Wilfried http://www.mestdagh.biz Wednesday, May 18, 2005, 15:01, Guillaume MAISON wrote: Hi everyone, i'm wondering about the way to implement a FTP server (with thread on GetProcessing) within a Windows Service ?

There is nothing very special to make a service using ICS. As long as there is a working message pump, ICS component will work. For the GUI, you use another application, a GUI application that communicate with the service using ICS, probably using the HTTP server component which offer the eaisiest way to build an administrative interface without writing another application: you just use a browser to do the administration. -- Contribute to the SSL Effort.

Re[2]: [twsocket] Receive result of the first ReceiveStr() call twice
Hello Francois, Thanks for the quick reply. No, I don't have any message handler of my own in my code. I create an object as the owner of an array of TWSocket objects. I assign the even handler of the TWSocket objects to a member function of that owner object and call ReceiveStr() in the OnDataAvailable handler.

Re[2]: [twsocket] Receive result of the first ReceiveStr() call twice
Hello Wilfried, Sure. Below is my event handler code. Hope I'm doing something wrong, otherwise, it's really strange. TProxyChecker is the owner object of the TProxySocket object array. TProxySocket is derived from TWSocket. procedure TProxyChecker.WSocketDataAvailable(Sender: TObject; ErrCode: Word); var s: String; begin if ErrCode = 0 then with TProxySocket(Sender) do begin s := ReceiveStr(); Log(s); Close(); end; end; The destination server is a commercial http proxy server. I tried using #13#10 and #13#10#13#10, I different strings read back from ReceiveStr. But the second string includes the first string in both cases. So it shouldn't be the server sending the string twice.

Re[2]: [twsocket] Threaded client?
Hello Francois, I'm not using a TDataModule but as I mentioned in my other email, I created an object to own the array of TWSocket objects. Now I have a new question that relates to the dependency of the main form. I'm reusing the sockets. So when a socket is disconnected, I assign a different IP and connect again. I understand that I can not do this in the OnSessionClosed event handler (or that didn't work.) Instead, I need to post a message to the main form, and reconnect in the windows message handler. This also introduces a dependency to the main form, and adds and some code in the main form unit. Is there any other way to defer the call to the Connect function so that it will happen after the code exits the OnSessionClosed event handler? I know I can create a hidden window in the owner object but I would avoid doing that if there is an easier way. -- Best regards, Jack The reason I was thinking of a multi-threaded client is that I want to isolate this module with the main form. FP No need to have multithread for that. Just put your TWSocket into a FP TDataModule. It's enough. FP You can evn create them dynamicall in a pure .pas unit. FP fyi: Message handlers can be put everywhere, it doesn't matter. FP - Original Message - Hello Francois and all, I saw a thread server sample in ICS package but did not see any sample for threaded client. I understand that with ICS I don't have to do multi-threading. The reason I was thinking of a multi-threaded client is that I want to isolate this module with the main form. The module is supposed to create multiple sockets to test a group of servers. I suppose this can be achieved with an array of wsocket objects in a single-threaded application but the socket will have to have something to do with the main form? For example, parent-ed by the main form, or the message handlers defined in the main form. (I could be wrong.) That's why I'm thinking of using a separate group of threads to do the server check. I wonder if there are samples for the client. -- Best regards, Jack -- 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
