Hi all

I want to know what the best way of reading a TIdTCPClientConnection is, I am using the following code in a Timer event:
 char * Buffer = NULL;
 try
 {
  try
  {
   Timer1->Enabled = false;
   IdTCPClient->ReadFromStack(false,100,false);
   TMemoryStream *pStrm = IdTCPClient->InputBuffer;
   if(pStrm->Size > 0 )
   {
    Buffer = new char[pStrm->Size + 1];
    ZeroMemory(Buffer,pStrm->Size + 1);
    pStrm->Position = 0;
    pStrm->Read(Buffer, pStrm->Size);
    pStrm->Clear();
    ShowMessage(Buffer);
   }
  }
  catch(Exception &E)
  {
   ShowMessage(E.Message);
  }
 }
 __finally
 {
  delete [] Buffer;
  Timer1->Enabled = true;
 }

The problem is that when I move the app window around, it is not smooth - I think ReadFromStack causes it. When I reduce the time-out, it doesnt notice when data is sent to the socket.
My understanding is that I need the following to see when data is available for reading:
1) a TIdTCPClient
2) a Timer
3) Do ReadFromStack in the timer
