indy

It's time for this question again, but this time with Delphi XE2. I am using the Indy version 10.5.8.0 that ships with XE2, and I have tried four different versions of the SSL dlls. I have tried 1.0.x latest, and about 3 different 0.9.8 versions (e,h,x,....). None of them works, when communicating to https:// urls at calendar.google.com. The author of the Delphi Google Calendar component at " Sync-components.com " ships his own binary openssl DLL runtimes that have no version information in it, but it seems to be a very small, very old version of SSL libs older than 0.9.8. The author of the

I am using Delphi and I want to determinate the physical MAC address of a network device in my network, in this case the Router itself. My code: var idsnmp: tidsnmp; val:string; begin idsnmp := tidsnmp.create; try idsnmp.QuickSend('.1.3.6.1.2.1.4.22.1.2', 'public', '10.0.0.1', val); showmessage(val); finally idsnmp.free; end; end; where 10.0.0.1 is my router. Alas, QuickSend does always send "Connection reset by peer #10054". I tried to modify the MIB-OID and I also tried the IP 127.0.0.1 which connection should never fail. I did not find any useable Tutorials about TIdSNMP at Google. :-(

How can I login to a Gmail account and get number of messages in the INBOX mailbox with TIdIMAP4 component ? To get the total number of messages in your Gmail's inbox, you need to, first connect to the Gmail IMAP server with your credentials, select Gmail's inbox mailbox and for that selected mailbox read the value of the TotalMsgs property. In code it may looks like follows (this code requires OpenSSL, so don't forget to put the libeay32.dll and ssleay32.dll libraries to a path visible to your project; you can download OpenSSL libraries for Indy in different versions and platforms from here )

How should I be recovering in this situation? The server crashes, thus the connection has been abnormally closed. Calls to almost everything result in "Connection Reset By Peer" exceptions. I seem to have fixed it by calling Disconnect on the TIdTCPClient object inside the except block, but it results in one final exception with the same message (which I have caught in the second try-except block). This is with Indy10 and Delphi XE2. try if not EcomSocket.Connected then EcomSocket.Connect(); except on e: Exception do begin try EcomSocket.Disconnect(); except MessageDlg('Connectivity to the

How can Indy's TIdTCPClient and TIdTCPServer be used in the following scenario: Client ---------- initate connection -----------> Server ... Client <---------------command------------------- Server Client ----------------response-----------------> Server ... Client <---------------command------------------- Server Client ----------------response-----------------> Server The client initiates the connection , but acts as a "server" (waiting for commands and executing them). The OnExecute approach of TIdTCPServer does not work well in this case (at least I am not getting it to work well). How

I am messing around with the Indy 10 supplied with Delphi 2009 and am having trouble with getting all the data from the IOHandler when OnExecute fires... procedure TFormMain.IdTCPServerExecute(AContext: TIdContext); var RxBufStr: UTF8String; RxBufSize: Integer; begin if AContext.Connection.IOHandler.Readable then begin RxBufSize := AContext.Connection.IOHandler.InputBuffer.Size; if RxBufSize > 0 then begin SetLength(RxBufStr, RxBufSize); AContext.Connection.IOHandler.ReadBytes(TBytes(RxBufStr), RxBufSize, False); end; end; end; AContext.Connection.IOHandler.InputBuffer.Size doesn't seem
