Send TCP Port a command

awarn · 2008-03-03

Hi,

I could not find an answer in the forum so I am hoping someone has come across it before.

I have to send data to a scale through a TCP Port. I will be sending an IP address, port number, and then a command as text.

Has anyone done this before?

I am thinking it should be as simple as decalring some variable, and then two lines of code like:

somevariable.open('192.168.1.15::52200');
somevariable.write('w.261.2' + formaT(weight));

Does anyone know how to open a TCP Port (I hope I am using the terminology proprely) and send this command?

Thanks,

Look to the Communication Components for NAV. If you will find file "devguide.chm", you will find this example:

The Navision Socket Bus Adapter - Sending a Document
In this example, we use a codeunit to initialize the Navision Communication Component, establish contact to the Navision Socket Bus Adapter, open a socket server for the bus adapter and send the message.

For the purpose of this example, we have defined the following variables:

Variable Name
Data Type
Subtype
Length

CC2
Automation
'Navision Communication Component version 2'.CommunicationComponent

SBA
Automation
'Navision Socket Bus Adapter'.SocketBusAdapter

OutMsg
Automation
'Navision Communication Component version 2'.OutMessage

OutS
OutStream

The socket server uses port 8079 on the local machine.

Example
OnRun()

IF ISCLEAR(CC2) THEN
CREATE(CC2);
IF ISCLEAR(SBA) THEN
CREATE(SBA);

CC2.AddBusAdapter(SBA, 0);
OutMsg:= CC2.CreateoutMessage('Sockets://localhost:8079');

OutS:= OutMsg.GetStream();
OutS.WRITE('First Text');
OutS.WRITE('Second Text');
OutS.WRITE('Third Text');

OutMsg.Send(0);

Thanks - but I do not see 'Navision Communication Component version 2' as one of the automation variables available to me.

Where do I go to add it - is there a dll somewhere I can download?

Thanks,

They are part of NAV Client installation, but are not included in the standard installation type. You need to run NAV install again and add the component "Commerce integration" or how it is named. After that, you will have these components available.

Hi,

Thanks, I just pulled these two dlls from the CD and registered them:
NSComCom2.dll
SocketBusAdapter.dll

Can you verify that the syntax of the IP address would be something like the below?

I am using 192.168.0.1 & port 52200 as examples, they would end up being parameters. Is the 'Sockets://' text necessary?

OutMsg := CC2.CreateoutMessage('Sockets://192.168.0.1::52200');

Thanks for all your help, this is helping me a lot!

1) Use just one colon between address and port
2) The "sockets" is name of used protocol. (like http, ftp, skype etc.). I do not know, if the components supports another protocol than "tcp/ip sockets".

Howdy, Stranger!
