<div class="markdown_content"><p>I'm trying to open the HTML5 demo's to get a better understanding of how to program a custom HTML5 control, and I cannot open any of the demo files in the HTML5 Control Editor.</p> <p>I am met with **"The type initializer for '3S.CoDeSys.DeviceObject.DeviceObject' threw an exception. Do you want to view the file in your default editor?" <br/> which then opens in the browser. Any ideas on how to correct this?</p> <p>Also, is there a more robust guide for creating HTML5 controls? The documentation appears to be severely lacking. It does not show what variables are generated from the code and/or how to use them in ElementWrapper.JS, and I cannot open the existing files in the HTML5 Control editor to attempt to reverse engineer them.</p></div>
