How to save a file from the internet to the hard drive using LabVIEW

[StanlyKupp]

For instance, how would I copy this file to my hard drive:

http://sine.ni.com/images/global/us/logo.gif

Thanks.

You need VIs to handle the HTTP protocol. The Internet Toolkit (Part of the Enterprise Connectivity Toolset) has those VIs. Also the OpenG Toolkit contains HTTP Vis. Unfortunately they are not yet released as a downloadable package (but variants of them are used extensively in the OpenG Commander). You can access those VIs from the CVS repositery though (http://cvs.sourceforge.net/viewcvs.py/opengtoolkit/http/)

The easiest "built in" method is to use the DataSocket Read VI, which can grab an arbitrary file via HTTP or FTP as long as you append the string "[text]" to the end of the URL. See the Retrieving an Unformatted Text File via FTP or HTTP Using DataSocket KnowledgeBase entry.

In your case, use the following input for the "connection in" input:

If you wire a string to the "type (Variant)" input, the output can be written directly to a file.

Check the following example. You should easily modify it to download the image to a directory in your hard drive.
