How to read the data in a txt file on a web site?

[TomTurbo]

I want to extract the numbers located in txt files on a web site. It's a normal url. Not a ftp.

Does anyone know how to do it?

TomTurbo;

You can use the DataSockets VIs to perform what you want. The key is to use the expression [text].

If you go to my website VI Security.com and check the Products & Tools section, there is a download called VIs for random.org. Check the VI called "Check Buffer (random.org).vi". If you type the URL of your .txt file you can then extract the numbers.

Thanks for answering
The web page is full of txt files that I can download manually very easy.
The files are full of measurement data which I want to process.

The VI you have attach is version 7.1 and I have 7

Tom,

Take a look at the attached VI. I am not sure how you interpret the data but this grabs the data as a 1024 by 169 array and graphs it for you.

Notice I take the URL and add [text] to retrieve the string.

[TomTurbo]

This is exactly what I want Evan.

I'm only using the evaluation version of LabView which
seems to be 7.0 and it can not run your vi, since it 7.1.

It's really a pity since I want to see this work before I buy it.

Any idea? Could you save it as 7.0 or ?

Thanks
Tom

Tom,

Here is the VI. If it doesn't come through, all you need is a Datasocket read, and the url is http://(your url)[text] The text portion being the key. I then just sent the response throught the spreadsheet string to array function.

Thank you so much Evan.

It works fine
