LabVIEW

Hi Pojoaque,

Thanks for the post and I hope your well.

What version of LabVIEW are you using and which example is it? 

The error either means that you have entered the wrong URL or that the address that you have requested has moved. Also, it can be linked to a server failure. What would be wise to do in first hand is to ping for the website, to see if it is still available through the server. I would also check your setup.

Also, please look at the following link for more information on Web Services and issue,

Hope this helps,

Hi,

Also check to make sure the LabVIEW Web Server is running and that it is enabled for Web Services.  You can find it in Tools >> Options.  It is not enabled by default. 

Hi Pojoaque,

Thanks for the update. Which example is called add? 

Maybe its the address book example, if so, please see this KnowledgeBase article with a known issue with this example - also please double check your configuration of LabVIEW. 

In the VIs you create yourself what are you trying to do?

Why Does the Address Book RESTful Web Service Project Found in the LabVIEW 8.6 Example Finder Not Work?

If its the VI itself which does work - have you checked your LabVIEW configuration allows access to the webserver for all vis?

Hope this helps, 

Hi Hi Pojoaque,

I hope your well.

I was wondering if any of the advice given thus far has resolved your issue?

Thanks,

Hi Pogoaque,

Thanks for getting back to us.

If you take a look at these two links,

 You'll notice one of the negitives for the Web Server is a flashing image update -as the front panel is an image. 

For the Web Serice article, under advanced - it talks about streaming data. There is a zip example - this may help.

Hi,

You can set a web method VI to be streaming, and then use the Write Response VI to stream the response (use it in a loop).  You can also use AJAX to do a periodic refresh.
