Can I use labview to access to Internet?

[JohanZhang]

If i know the file link on the internet, i want to use labview to download this file not through IE exploer.
Can I? Where can i found this VI?
Thanks a lot.

anything is possible, I am curious why you do not wish to use explorer?  There is an example of embedding an explorer window in labview, you can load ur url there and it should start the download.  Just a thought.  If you know the ftp site... if it is on ftp, you can look at those examples.  I have not tried to put web addresses in the file dialog and suspect that wouldn ot work.

Easiest would be to use Datasocket reads. It supports a variety of protocols (file, http, ftp, opc, dstp, psp)

For an overview and tutorial see: http://zone.ni.com/devzone/cda/tut/p/id/3224

Good luck! 🙂

Thank you very much for the reply.

But can you give me a more detailed case? I can not find a vi that tells how to download file from http.

thanks again.

Hi Johan,

have you read the link by Altenbach? Some of the paragraphs also describe (with pictures) how to download websites (http) or files (ftp)...

Data communications palette, data socket.  See attached example

I recall knowing this in the distant past... but thanks for the refresher information.... It actually is going to be integrated into a program that I am currently working on.

i am using Labview7.1.
So can you send me a vi V7.1?
thanks very much.

attached 7.1.. but since I do not have that version.. all I could do is verify it opens in 8.  So hopefully it still works.

[JohanZhang]

I can  open it now, thanks.
But actually, i 'd like to download file(xls) from http.
can i?
