问题 I am trying to send a TStringStream from client to server, then send it back from server to client, using Indy TCP components. Here is my client code: var Jpg: TJPEGImage; StringStream: TStringStream; strcams, StringImageData: String; byt, i: integer; procedure SendCommandWithParams(Command, Params: String); begin Lock; try if not FTCP.Connected then begin exit; end; FTCP.Socket.WriteLn('1' + Command, IndyTextEncoding_UTF8); FTCP.Socket.WriteLn(Params, IndyTextEncoding_UTF8); finally Unlock;

问题 I have this horribly stripped delphi code that basically login to server, save cookie in a global cookie manager, then upload files in threads (using Delphi 2010 + Indy 10.4736) Each thread reads the global cookie manager and upload the file. Server side, I'm using PHP with CodeIgniter . Everything works just fine, except that CodeIgniter has this sess_time_to_update setting in config. This *sess_time_to_update* defaults to 300 seconds after which CodeIgniter completely regenerate the session

问题 I can't to publish my iOS app to AppStore. Delphi 10.1.2 Berlin, iOS64, Win 8.1. I received the next info from apple: Thank you for your response.

问题 I have a client and a server application that is communicating just fine, there is a TIdCmdTCPServer in the server and a TIdTCPClient in the client. The client has to authenticate in the server, the client asks the server for the newest version information and downloads any updates, and other communications. All this communication with TIdTCPClient.SendCmd() and TIdTCPClient.LastCmdResult.Text.Text. The way it is, the server receives commands and replies, the clients only receives replies,

问题 i'm currently creating a little mail client and facing a problem with charset. I use indy's TIdIMAP4 component to retrieve data from mail-server. When i try to retrieve mail bodies then accent letters like ä, ü etc are converted to =E4, =FC respectively as it is using charset ISO-8859-1.

What would be the best solution for that
