Language: Delphi Compiler: Delphi 2005 --------- Hey all I've made a program using TServerSocket and TClientSocket. I would like to change this program to use Indy's TCP Client/Server (due to the multi-threading within the indy-components). This has though caused some problems for me as i've used buffers (records) to send most of the data. My problems are: ---- 1) How does these commands look using IdTCPClient? ClientSocket.Socket.ReceiveBuf(Buffer, sizeOf(Buffer)); ClientSocket.Socket.SendBuf(Buffer, sizeOf(Buffer)); ---- 2) How does these commands look using IdTCPServer? ServerSocket.Socket.SendBuf(Buffer, sizeOf(Buffer)); ServerSocket.Socket.ReceiveBuf(Buffer, sizeOf(Buffer)); ---- 3) And how is this done with IdTCPServer? procedure TMainForm.SendMessageToAll(Buffer: TUser); var i: Integer; begin for i:=0 to ChatServerSocket.Socket.ActiveConnections-1 do begin ChatServerSocket.Socket.Connections.SendBuf(Buffer, sizeOf(Buffer)); end; end; ---- The variable "buffer" is of this type in all questions: TUser = Record Command: String[50]; Username: String[50]; Password: String[50]; end; Examples how to use buffers with the TCP Indy-components would be very welcome. So far I haven't been able to locate much info about it on the net. Thanks in advance, Søren
