Description of Operation

The NI Stats VI Utility enables the user to easily check the status of files posted on the NI Community web site.

The user can select files to monitor and update the statistics for those files manually or based on a configurable time interval.

To easily add files to the list of files to monitor, copy the URL string from your web browser and paste it into the URL String column of the table shown in the Select Files to Monitor window.

The NI Stats VI Utility stores the list of files to monitor at the following path:

NIStats\Data\ FilesToMonitor.txt

The NI Stats VI Utility stores a log file at the following path:

NIStats\Data\ Community Stats Log.txt

The Community Stats Log.txt file is updated once per day that the NI Stats VI Utility runs.

The Community Stats Log.txt file is formatted so that you can import the data into a spreadsheet program if you want to perform a more detailed analysis of the data.

Extracting the files

The NI Stats VI Utility is supplied as a zip archive containing all required items. The zip archive contains full path information.

When extracting the items, set the path to C:\. Since the zip archive includes full path information, the included items will be extracted to the following path:

C:\Program Files\NIStats

Change Control:

07-29-2008: Modified the NI Stats - Update Stats.vi to parse the Title immediately after reading the page source. This accounts for the change to the NI Community web page structure that no longer includes the title of submitted items in the URL.

07-29-2008: Modified the NI Stats - Parse Title From Community Page Source.vi to account for the change to the NI Community web page title record so that "NI Communities: " is not displayed in the File Name field of the main interface VI.

07-29-2008: Modified the first search string in the NI Stats - Parse Download Count From Community Page Source.vi to reflect the new tag used in the page source.

Updated links to other example code to account for the change to NI Community URL formatting for submitted items.
