== What I want to do:
1)  Use HTML instead of the VB forms to present my User Interfaces inside
applications that can run on "any" desktop running Win98 and higher.
2)  Run the User Interface inside a WebBrowser

== What is the best approach?
Does anyone have any experience on how to do this?
(Even parse .ASP or .ASPX scripts on clients?)

== Have I built apps with HTML frontends before?
Yes. .
 I build Web-applications running on IIS to:
1)  Maintain the content of databases
2)  Zip and unzip large files on remote machines
3)  Maintain files on remote machines
4)  Publish database-content to static files.

Business logic is stored in DLLs and called via
   server.CreateObject("theDLLreferrerName.ClassName")

== Why on desktops?
HTML and DHTML offer me much more flexibility in building self-adapting user
interfaces.

A new version of a desktop app. to be developed for one of my clients will
run based on 3-tier architecture using HTML for the presentation layer, VB
for the Business Layer and MS Access for the Database Layer.
