VirtualUI. It’s a web-enabling SDK to run Windows apps on the browser. Works with VB6 and many other languages as well: Delphi, C#, C++, etc
, without rewriting the original app its for publish or extended cycle of life app
Really i think is alternative to start to program in Androis SDK for mobile device or save money
