Well, some thing is not right...
On server my code for send a bitmap from a TImage componenet is:

void __fastcall TForm1::Button1Click(TObject *Sender)
{
    TMemoryStream* pms = new TMemoryStream();
    Image1->Picture->Bitmap->SaveToStream(pms);
    pms->Position=0;
    ServerSocket1->Socket->Connections[0]->SendStream(pms);
}

None erros cod generated, but i'm not sure about what to do to read wich ReceiveBuf on the client side, i'm trying to use this:

void __fastcall TForm1::ClientSocket1Read(TObject *Sender,
      TCustomWinSocket *Socket)
{
    short count=Socket->ReceiveLength();
    char *Buf = new char[count];
    Socket->ReceiveBuf( Buf, cont);
    TMemoryStream* pms = new TMemoryStream();
    pms->Write(Buf, cont);
    pms->Position=0;
    Image1->Picture->Bitmap->LoadFromStream(pms);
}

In this way many errors happen. :(
Any help please
Thanks Byanex
