This VI is complicated. It uses internet explorer to get the string information via ActiveX.

I'm not usre if this will help, but it captures the HTML code of a web page - maybe you could then parse the string for the text you are looking for?

If you want to save a file from the web, a good way to do this is using a Datasocket Read.  There is an example of downloading and saving an image using the datasocket read VIs here:
 
Displaying an Image from the Web in LabVIEW
 
From here you should be able to extrapolate how to save different types of files from a website.  I hope this helps.  Have a great day.

Thank you,
your nice vi can download images and i will use it in the future. At momemt I need to download .pdf file. I tried datadocket  based vi but the site, in which i found pdf file, don't let me download (other sites let me). In a second step I used an activex based vi and I could see in the browser my document opened in Acrobat Reader. But in order to save the file I have to know some other thing.
The Vi  I tried to use are:
Get_page_&_HTLM.llb
SimpleBrowser.vi 
Regards
Marzi
