What are ActiveX and OLE?

[muhammadSufyan1]

The specification for ActiveX controls has been relaxed to give developers the ability to create smaller, faster controls that are more suitable for the Internet. In the new object linking and embedding (OLE) control specification, we make use of component categories, which relax previous rules that identify interfaces as being mandatory and allow greater flexibility to efficiently target certain areas of functionality without having to provide superfluous support to qualify as a control. The OLE control specification also adds some new features such as windowless objects, URL monikers, asynchronous monikers, progressive downloading, and OLE Hyperlinks. Perhaps most importantly, you can mark controls as safe for data download and safe for scripting.
