The software is written mostly in PHP. An optional C++ version of the counting engine is provided. Pie charts require PHP's graphics extension. It is optimized so that it performs well for large-scale polls (more than 100,000 votes). Also, it works well on a wide range of browsers, including text-only browsers like Lynx.
Use DemoChoice in your presentation or convention!
The best reason to download DemoChoice is to run it on a laptop or tablet for use in a presentation or at a convention table. Install xampp (a self-contained version of apache and php) on your USB memory stick or laptop, copy the DemoChoice files in a folder named "dc" to the xampp/htdocs folder, and start apache from the xampp control panel. It is not necessary to install any xampp components other than Apache and PHP. Then send your browser to http://localhost/dc and you should be in business. Of course, web server installations other than xampp can work too.Create highly customized polls!
If you want to embed a DemoChoice ballot in a complex web page, create a new ballot style or counting method, or link a poll to your own database of voters, you can install DemoChoice on your own website.
Note: In most cases, it's easier to just create a poll here and link to it.
