Indy 10 TCP send/receive file

I have an example on sourceforge for this
https://sourceforge.net/projects/internetdemos/

but basically, to make the indy 9 demo work for indy 10, you need to change just a couple of things
this is from memory, so excuse typos.

uses IDStreamVCL;

var
     AStream: TIdStreamVCL;

begin
      AStream := TIDStreamVCL.Create(
        TFileStream.Create(ExtractFilePath(Paramstr(0)) + 'In\' + Filename, fmCreate), True);
     try
         AContext.Connection.IOHandler.ReadStream(AStream, Filesize, False);
     finally
         FreeAndNil(AStream);
     end;
end;


var
     AStream: TIdStreamVCL;

begin
      AStream := TIDStreamVCL.Create(
        TFileStream.Create(ExtractFilePath(Paramstr(0)) + 'In\' + Filename, fmOpenRead), True);
     try
         AContext.Connection.IOHandler.WriteStream(AStream, Filesize, False);
     finally
         FreeAndNil(AStream);
     end;
end;

Please note
-------------
If you are using later versions of Indy 10 than what ships, TIdStreamVSL was replaced with just TIDStream

uses IDStream, IdSyncObjs (might be IdSync, can't check right now)
and it's something like :-
var
   AStream: TIdStream
begin
  AStream := TIdFileStreamCreate(....


Let me know if you're using a later version and I'll look up the commands at work later on

What I tend to do is send the filename, the filesize, and then the file
That way, the server knows what to call the file, and how big it is supposed to be

for later versions of Indy 10 (which the Indy team recommend), you would do :-

--client

uses
        IdObjs, IdSys;

var
   AStream: TIDStream;

begin
   TCPClient1.Connect;
   TCPClient1.IOHandler.LargeStream := True; // fully support large streams


   AStream := TIdFileStream.Create(filename, fmOpenRead + fmShareDenyNone);
   try
       TCPClient1.IOHandler.Write('FILE'); //send command "FILE"
       TCPClient1.IOHandler.Write(ExtractFilename(filename)); // send file name
       TCPClient1.IOHandler.Write(IntToStr(AStream.Size)); //send file size

       TCPClient1.IOHandler.Write(AStream);
   finally
       FreeAndNil(AStream);
   end;
...



--server

uses
        IdObjs, IdSys;

procedure TfServerMain.IdTCPServer1Connect(AContext: TIdContext);
    begin
        AContext.Connection.IOHandler.LargeStream := True;
    end;


procedure TfServerMain.IdTCPServer1Execute(AContext: TIdContext);
    var
        InCmd: string;
        AStream: TIdStream;
        S: string;
        FileSize: Int64;
        Filename: string;
    begin
        InCmd := ReceiveStringWithLogging(AContext);
        if InCmd = 'FILE' then
        begin
//followed by separate FILENAME, then FILESIZE, then the actual STREAM
            Filename := ReceiveStringWithLogging(AContext);
            S := ReceiveStringWithLogging(AContext); // filesize
            FileSize := StrToInt(S);
            ForceDirectories(ExtractFilePath(Paramstr(0)) + 'In');
            AStream := TIDFileStream.Create(ExtractFilePath(Paramstr(0)) + 'In\' + Filename, fmCreate);
            try
                AContext.Connection.IOHandler.ReadStream(AStream, Filesize, False);
            finally
                FreeAndNil(AStream);
            end;
        end;
   end;

Thanks, been looking for a solution the last 4 days. Only one thing if some one else read this.
To get this to work the client code have to be changed from :

       TCPClient1.IOHandler.Write('FILE'); //send command "FILE"
       TCPClient1.IOHandler.Write(ExtractFilename(filename)); // send file name
       TCPClient1.IOHandler.Write(IntToStr(AStream.Size)); //send file size

To:

       TCPClient1.IOHandler.WriteLn('FILE'); //send command "FILE"
       TCPClient1.IOHandler.WriteLn(ExtractFilename(filename)); // send file name
       TCPClient1.IOHandler.WriteLn(IntToStr(AStream.Size)); //send file size

If not, the server get all text on one line.
