问题 When using Delphi 2007 along with Indy 9, what are the latest OpenSSL libraries that can be loaded and where are they available? 回答1: You need the following two DLLs: libeay32.dll ssleay32.dll You can download the source from the open-source organization OpenSSL.org, but then you have to compile the DLLs yourself. Indy maintains a site of compiled binaries for each version of Indy and OpenSSL (see indy.fulgan.com/SSL and indy.fulgan.com/SSL/Archive -- thanks to TLama for the links). Older

Indy9 Get Raw Email header?

由 你。 提交于 2019-12-13 21:35:46
问题 Does Indy9 have any way to get a specific raw email header (say, "Subject" or "From") which still includes the transfer-encoding (ie: has not been mangled by DecodeHeader on older versions of Delphi with poor Unicode support), or would I have to parse the entire email header manually to extract this information? 回答1: The TIdMessage.RawHeaders property is what you are looking for, eg: Subject := IdMessage1.RawHeaders.Values['Subject']; 回答2: I have solved the problem, calling IdMessage1.Headers

问题 I am investigating a problem with a legacy executable, written in Delphi 5, utilising Indy 9. Components in use: TIdHTTP, TIdConnectionIntercept & TIdSSLIOHandlerSocket. The problem the app is presently experiencing is slow responses to TIdHTTP POSTs. I found the following two links: Delphi: Why does IdHTTP.ConnectTimeout make requests slower? Delphi TIdHTTP POST is very slow vs GET Based on the links, I have tried the suggestions of: (i) setting ConnectTimeout to zero and (ii) setting the

My current programs is the following (I am using a Thread): procedure TThreadRead.Execute; var buffer: array [0..755] of byte; //s1: string; //i: integer; begin IdTCPClient1.RecvBufferSize:= 756; IdTCPClient1.Connect; while Terminated = false do begin if IdTCPClient1.InputBuffer.Size = 0 then

问题 I would like to add roots to a VirtualTreeView http://www.delphi-gems.com/index.php/controls/virtual-treeview with a thread like this: function AddRoot ( p : TForm1 ) : Integer; stdcall; begin p.VirtualStringTree1.AddChild(NIL); end; var Dummy : DWORD; i : Integer; begin for i := 0 to 2000 do begin CloseHandle(CreateThread(NIL,0, @ADDROOT, Self,0, Dummy)); end; end; The reason for this is that I want to add all connections from my INDY Server to the TreeView.

Indy's onexecute/onconnect get's called as a thread. So if 3+ connections come in at the same time the app crashes due to the TreeView.

问题 Im trying to write a server/service that broadcasts a message on the lan ever second or so, Kind of like a service discovery.

Im using delphi7, with indy 9.0.18 where im stuck is if i should be using UDP(TIdUDPClient/Server) or IP MultiCast (TIdIPMCastClient/Server) or if its even possible...
