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!

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

That is what the OnWork events are for. But you did not show where they are being assigned, or what their code looks like. Quote: TMemoryStream* strm = new TMemoryStream; 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); ...

But you did not show where they are being assigned, or what their code looks like. 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? Quote: Why are you loading the entire file into memory before sending it?

I did not realize this function. thank you Johann Back to top Remy Lebeau (TeamB) Guest Posted: Mon Jan 23, 2006 7:37 am    Post subject: Re: TCP Client / Server "Margreiter" <ma (AT) soft-hard-ware (DOT) at> wrote Quote: I tried to get the information in th OnWork event: You are not differentiating between reading and writing activities. You should be looking at the AWorkMode parameter before processing the AWorkCount parameter. Quote: this event is never fired. 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?
