Hi,
I send files form a TCPClient to a TCPServer.

    Client:
    TCPClient->WriteStream(strm, true, true, strm->Size);

How can I get informations about status of transmition,
where can I read out how many bytes transmitted??

Thank you for help!
Johann

Use the OnWork... events.

I tried this already, but this event is never fired.
Are there some preparations necessary?

Yes, they are.

transmitting large files may take a long time, so I want to install a simple 
indicator, how many bytes are transfered.
try
{
       TMemoryStream* strm = new TMemoryStream;
       .....
       Form1->TCPDataClient->Host = IPAdr;
       Form1->TCPDataClient->Connect();

       strm->LoadFromFile(SPath);
       Form1->TCPDataClient->WriteStream(strm, true, true, strm->Size);
       .....
 }

That is what the OnWork events are for.  But you did not show where they are
being assigned, or what their code looks like.

Why are you loading the entire file into memory before sending it?  If you
use a TFileStream instead, then you can send the file directly

    TFileStream* strm = new TFileStream(SPath, fmOpenRead |
fmShareDenyWrite);
    ...
    Form1->TCPDataClient->WriteStream(strm, true, true, 0);
    ...

I tried to get the information in th OnWork event:
    void __fastcall TForm1::TCPDataClientWork(TObject *Sender,
          TWorkMode AWorkMode, const int AWorkCount)
    {
        StatusBar1->SimpleText = AnsiString(AWorkCount);
    }
but this event is never fired.
Do I have to assign or to initialize these events somewhere earlier?

I did not realize this function.

You are not differentiating between reading and writing activities.  You
should be looking at the AWorkMode parameter before processing the
AWorkCount parameter.

I can guarantee to you that is is ALWAYS triggered.  If it is not, then you
have a buggy version of Indy.  Which EXACT version of Indy are you actually
using?

That is an old build.  The current Development Snapshot is 9.0.50.  You
should consider upgrading, and see if the problem still persists.
