HTML Application

If a user removes Internet Explorer from Windows, via the Control Panel, the MSHTML engine remains and HTAs continue to work.

HTAs are fully supported running in modes equivalent to Internet Explorer versions 5 to 9.

This means it is confined to communicating with the server, manipulating the page's object model (usually to validate forms and/or create interesting visual effects) and reading or writing cookies.

Although HTAs run in this 'trusted' environment, querying Active Directory can be subject to Internet Explorer Zone logic and associated error messages.

This tag exposes a set of attributes that enable control of border style, the program icon, etc., and provide information such as the argument (command line) used to launch the HTA.

Editors with special features for developing HTML applications may be obtained from Microsoft[5] or from third-party sources.
