Hi,

I'm converting some code from Indy 9 to Indy 10, i use CurrentReadBuffer() 
to wait and retrieve all data available from the connection, now on Indy 10 
which method or methods can i use instead of CurrentReadBuffer() so i can 
get the same functionality?

Thanks in Advance

Call the IOHandler's CheckForDataOnSource() and InputBufferAsString()
methods, ie:

    Connection.IOHandler.CheckForDataOnSource(Timeout);
    Data := Connection.IOHandler.InputBufferAsString;

Thanks,

I allready tried that, but i have some problems with non-windows tcp 
clients(i.e. Mainframes) on Indy10(client gets a timeout), going to make 
more research to find out wich specifc ones doesnt work with Indy10. With 
Indy 9 works with no problems.

this is my for the Server Execute Method,
INDY 9:

ClientSession = (TClientSession*) AThread->Data;
  if (ClientSession != NULL)
   { if (AThread->Connection->Connected())
      { NewData = AThread->Connection->CurrentReadBuffer();
        if((NewData != "")
        ClientSession->NewDataReceived(NewData);
      }
   }

INDY 10
  ClientSession = (TClientSession*) AContext->Data;
  if (ClientSession != NULL)
   { if (AContext->Connection->Connected())
   { 
AContext->Connection->IOHandler->CheckForDataOnSource(AContext->Connection->IOHandler->ReadTimeout);
  NewData = AContext->Connection->IOHandler->InputBufferAsString();
  if (NewData != "")
     ClientSession->NewDataReceived(NewData);
   }
   }

Then the client is likely not sending any data to begin with.  There is
nothing in the code I have given you that can raise an timeout exception.

TCP is TCP regardless of whether you use Indy 9 or 10.  If the data being
sent is the same, then Indy 10 should be working fine for you.

You shouldn't really be checking for Connected() at all, in either 9 or 10.
Let Indy raise an exception when you try to read from a socket that has been
closed.  That will notify the server to shut down the thread for that
connection.

Try this instead:

    ClientSession = (TClientSession*) AContext->Data;
    AContext->Connection->IOHandler->CheckForDataOnSource(IdTimeoutDefault);
    NewData = AContext->Connection->IOHandler->InputBufferAsString();
    if( (NewData != "") && (ClientSession != NULL) )
        ClientSession->NewDataReceived(NewData);
