Passing data through TCP/IP

[AndreiN2014]

Hello ! My challenge is this: I have a vi that i have to use as a server and a vi as a client. In the server vi, i want to modify multiple parameters of one graph and these modifications should reflect on the client vi. How can i transmit, through TCP/IP, the modified graph to the client vi/application ? I would appreciate very much a link or a example vi that can show me exactly how such an opperation can be achieved. Thank you!

There is a good example doing this on the example finder.

Hello ! Quick answer 🙂 Thank You. what should i look for ?
I have already looked at the exemples of TCP/IP server /client configuration examples...but i didn't find anything...I may have missed that example...could you (PLSS) be more specific ??.. Thank you very much !

Are you looking to transmit the properties of the graph or the data.  I might have misspoken.  You can send a string over TCP capturing these properties, parse them at the client and write the values to the correct property node.

Both ...the data& the propeties of the graph...if such a thing is possible.

I have just started 2 work in LabView...I don't have much experience ...so an example or a walk throug woul be very much appreciated...Thank's for taking the time to answer my question.

You can make the string you pass include any data.  Here is a simple example using an XML string.

<Graph>

<Value>1,2,3,4,5,6</Value>

<Visible>True<\Visible>

</Graph>

Send this string on the server side taking a reference to a graph and build a simple vi to generate a string containing  the data you want to send.

At the client side you parse this string an a loop as set the appropriate property node as the tag dictates.

I cant think of a precanned solution for this but my morning coffee has not kicked in yet.

Thank's !!

For just the data the examples are the 'simple data client' and 'simple data server' examples.  Sending properties are a little harder.

Would it help if i posted my vi's ?
