Measuring network traffic with Indy

阅读更多关于 Measuring network traffic with Indy

I'm using a TIdTCPCmdServer to handle all communication with client applications. I would like my server to log all kind of stuff including network traffic. Is there any easy or clever way to see how much bytes the TCPCmdServer actually received and sent? I can only think of code like ASender.SendReply; Inc (FTraffic, Sizeof (ASender.NormalReply.Code) + Sizeof (Char) * ASender.NormalReply.Text.Length)); which is extremely ugly in my opinion because these traffic updates would be spreaded out all over my code and are fairly complicated as well. Any suggestions? Thanks for your help. Look into

阅读更多关于 How to send several emails in a single connection of IdSMTP?

问题 I am using Indy 10 on C++Builder 6.0 Professional Edition. My SMTP server imposes a limit on the number of connections in a certain time interval, so I need to send more than one email using the same connection. Is it possible? How can I do that ? I am already able to connect and send one email on each connection. Thank you very much for any help. 回答1: You can call TIdSMTP.Send() multiple times between a single pair of Connect() / Disconnect() calls, adjusting the TIdMessage as needed for

When does background threads prevent the process of being terminated?

阅读更多关于 When does background threads prevent the process of being terminated?

Our program creates a background thread at the beginning of the program. The background thread does some database integrity checks and checks for stuff in the Internet using Indy. After 10 seconds, the background thread should be finished and since FreeOnTerminate is true, it will also clean itself up. We have noticed that in some cases, if the user closes the program too quickly, the process will still be alive until the background thread is finished. Since we couldn't exactly reproduce the issue, I have created a demo project to try a few things: type TBackgroundThread = class(TThread)

问题 I know this question has been asked a number of times. I seem to have a bit of a different problem.

How to send a mail message using Indy's smtp server component?

阅读更多关于 How to send a mail message using Indy's smtp server component?

Since the demo given in http://www.indyproject.org/Sockets/Demos/index.EN.aspx only saves the received stream to a file, I don't know how to effectevely send that stream as a mail. Could anyone teach me how to do this or to point me some more complete example? A SMTP server component can't send mail - it can only receive it. You need a SMTP client component (TidSMTP) to send mail. A mail server when it sends mail acts like an SMTP client. Here's a complete example on how to send an email: VAR SMTP : TIdSMTP; VAR MSG : TIdMSG; . . MSG:=TIdMSG.Create(NIL); TRY WITH MSG.Recipients.Add DO BEGIN

Indy Write Buffering / Efficient TCP communication

阅读更多关于 Indy Write Buffering / Efficient TCP communication

I know, I'm asking a lot of questions...but as a new delphi developer I keep falling over all these questions :) This one deals with TCP communication using indy 10. To make communication efficient, I code a client operation request as a single byte (in most scenarios followed by other data bytes of course, but in this case only one single byte). Problem is that var Bytes : TBytes; ... SetLength (Bytes, 1); Bytes [0] := OpCode; FConnection.IOHandler.Write (Bytes, 1); ErrorCode := Connection.IOHandler.ReadByte; does not send that byte immediately (at least the servers execute handler is not
