Newbie Question - Streaming HTTP POST to a server

[Fall-Apart-Dave]

Hello

I have searched, and am continuing to do so, and may well have already found the answer an not realised yet. But, if someone better placed could help me I would be very grateful. 

I am trying to "learn" labview, and am tinkering with something written by someone else that needs modifcation. 

A quick background: 

We are reading strain gauges, and writing to a CSV file. In order to write, the program must be stopped, the file written, then restarted. 

We need it to stream live data to a server. 

I *think* I have modified it correctly to at least write "live" to a CVS rather than needing to be stopped and started, but I also need it to stream live to a server too. 

I have attached a snipped of the part of the circuit I need to modify. As I said, I think I have this correct for appending a CSV "live". 

How would I take the data and stream in the form of a serial string straight to, for example, here: 

http://posttestserver.com/

I'm looking at examples of other bits in the tutorial etc but they look a little over complicated. 

I appreciate I am likely asking a very basic question, and will likely get slapped with a very obvious pre-existing design, but at the moment I simply don't understand Labview well enough to realise what I am looking at half the time! So apologies for that. 

Many thanks

Dave

Hi Dave,

I recommend you check out the getting started examples provided with LabVIEW! They show some very clean code for many applications, including pushing data to a server.

LabVIEW example finder: http://www.ni.com/getting-started/labview-basics/examples

When you open up the Browse tab, you should see many folders. I'd recommend checking out the fundamentals to learn more about using LabVIEW in general. For your particular problem, I would look into the Networking folder, specifically the TCP&UDP folder.

Alternatively, you could use the HTTP VIs to post data to the server.
