indy10

问题 Using Indy10 - DelphiXE. How do I tell the telnet server I am connecting to with TIdTelnet to not echo the commands I send towards the telnet server? This is my current attempt (which doesn't work), I try to send the sequence IAC DO SUPPRESS_LOCAL_ECHO on each telnet write but I do believe this has to be done in the negotiating phase? uses TIdTelnet, ... procedure TIOTelnetConnection.SendSupressEcho; var Resp: TIdBytes; begin SetLength(Resp, 3); Resp[0] := TNC_IAC; Resp[1] := TNC_DO; Resp[2]

问题 We're having a bizarre problem with Indy10 where two large strings (a few hundred characters each) that we send out one after the other using TCP are appearing at the other end intertwined oddly. This happens extremely infrequently. Each string is a complete XML message terminated with a LF and in general the READ process reads an entire XML message, returning when it sees the LF. The call to actually send the message is protected by a critical section around the call to the IOHandler's

问题 I'm just starting to learn how to use the Indy 10 components in Delphi XE2. I started with a project that will use the command sockets ( TIdCmdTCPServer and TIdCmdTCPClient ). I've got everything set up and the client connects to the server, but after the client connects, any command the server sends to the client just freezes the server app, until it eventually crashes and closes (after a deep freeze). Project Setup The setup is very simple; there's a small server app and a small client app,

问题 I am trying to connect to smtp.live.com to send emails (live.com supports free pop3/smtp since 2009 apparently but this is totally news for me). Here is what happens when I try to connect to smtp.live.com port 587: Method sslvSSLv2 - timeout (obviously the server does not support SSL2) Method sslvSSLv3 - Error connecting with SSL. - error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number Method sslvSSLv23 - Error connecting with SSL. - error:140770FC:SSL routines:SSL23_GET_SERVER

问题 I want to download a file from FTP. If the file is small (usually under 1000MB) it works. However, if the file is big I get an EIdReadTimeout. Why? Should I keep the connection alive? From what I know reading data has its own channel so I don't have to keep the connection alive. What is odd is that the exception appears at the end of the Get (after Get successfully downloads the whole file): FTP.Get(Name, TempGzFile, TRUE, FALSE) !!!! Documentation: TIdFTP.ReadTimeout - Number of milliseconds

问题 Actually, my question doesn't have an answer there. I keep getting "EOF was observed" with solution (v23) of that answer. Only sslvSSLv2 gives a change "error:00000006:lib(0):func(0):EVP lib". Defective DLLs? According to the documentation it's pretty simple - have a DLLs and then just assign TIdSSLIOHandlerSocketOpenSSL instance to IOHandler property and switch protocol to https . But doing so, I've immediately faced an SSL error with message "Error connecting with SSL. EOF was observed that

问题 I'm using Idhttp (indy10 with delphi-xe2) to post form, but I get session expired message from the site, although I've already set cookie manager.

问题 I am using Indy 10 with Delphi.
