Is it possible to create a custom control, like ActiveX control using JAvaScript?
I have implemented a ActiveX control for PowerPoint using C# before. The control can be inserted, customized with properties and displayed in slide presentation. I am looking for a solution to create a new version using JavaScript. After studying for a while, I have only found some samples of creating add-in in Excel, Word or PowerPoint, and the samples show how to work with Excel spreadsheets, Word documents or PowerPoint slides. There is no sample of creating a custom Office control which can be used like an ActiveX control.
