  1. I've started to make some instructional videos on YouTube for my Messenger Library. I was inspired by Delacor's nice videos on their new DQMH framework and also by Steve Watts' CSLUG channel. Any feedback appreciated. James

  2. This is a weekend project (ok, several weekends now) I've been meaning to share for a while. It's a proof of concept which I'd like to get some feedback on before I invest more time. The idea is to provide a toolkit that uses LabVIEW webservices to serve an interactive HTML5 representation of any application's front panel(s) as an easy way to monitor and control the application (over the internet) without the need for heavy applications or runtime engines. Just a browser. And because not everyone is a also web-developer, the work required to create that website should be done entirely by the toolkit. In my solution it's as easy as dropping a single vi on the block diagram, that registers the VI with the FrontPanelManager which takes care of all the data exchange between the website and the front panel. Here's a screenshot of an example front panel showing all supported elements and its HTML version on chrome: Obviously, there are some cosmetic differences that can be fixed later. Controls on both LabVIEW front panel and HTML site act as controls and are synchronised across the two. By default, the website queries the front panel every 250ms for new data. The refresh rate can be changed with the cog button in the bottom right corner. To run it open the project start the WebService Get the URL of Main.html and point your browser to it start "To Publish/Main.vi" and watch the data appear in the browser As I said this is a proof on concept and it's a long away from being a toolkit. I'm working on functions that appear in the Tools menu to automatically add and configure the webservice and dependencies and many other things. [2014]FPPublisher.zip

  3. I'm aware of "the competition" and they all charge a lot. I've looked at LabSocket WebPager (after handing over $2k for the software they charge an additional $100 per hour for tech support. WTF?) WebPanel (similar but dead?) Wezarp (uses VNC) NI's own Web UI Builder (dead, mainly thanks to Silverlight requirement I heard). Is that what you meant, hooovahh? VIremote sounds like it's using different technology, since it seems to be limited to apple devices. I hadn't seem that one before. What I wanted to do is to provide an open-source, low-cost or free tool that allows the developer to achieve similar functionality as the above via a web browser. Get them started in a pain-free way and if they're keen provide the ability to modify to their own needs. I'm not a huge web designer myself. Enough to get this demo to work (for me at least) but for the final version I would probably need some input. There is a weird "bug". When you open the "Show Public URL" dialog the web service seems to freeze until you close that dialog again.
