Navision Communication Component OutMsg.GetStream

NavStudent

Hello I am trying to use Navision Communication Component to connect to another server.

I saw and downloaded the example code in here and I wanted to know if there is a documentation on these COM objects. Anything would be helpfull.

Sorry there is no such specific document available but you should go through the Navision help for ref.

thank you for the dev.chm file

I was looking at the document example code. And noticed this.

Example
OnRun()

CREATE(MQBus);

CREATE(CC2);

MQBus.OpenReceiveQueue('MyMessageQueueServer\comcom2_queue',0,0);

CC2.AddBusAdapter(MQBus,1);

CC2::MessageReceived(VAR InMessage : Automation)

InMsg:= InMessage;

IF (InMsg.ExpectReply) THEN

BEGIN

  InS:= InMsg.GetStream();

  InS.READ(Txt);

  MESSAGE(Txt);

  OutMsg:= InMsg.CreateReply();

  OutS:= OutMsg.GetStream();

  OutS.WRITE('Yes, hello world! OK.');

  OutMsg.Send(0);

END;

InMsg.CommitMessage();

The OutMsg.GetStream returns and istream. How can you assign this to outstream? How does navision compiles this?

OutS:= OutMsg.GetStream();
OutS.WRITE('Yes, hello world! OK.');
OutMsg.Send(0);



Thanks again.
