UserControls (Web/Win)

[Ole Hanson]

Hi

I have been wondering what did happen to the "universal" solution of being
able to use the exact same controls in both web and win? These guys are
called ActiveX controls and could in the old world (COM) be developed once
and then applied in both scenarios!

What is the .NET alternative to this??

Thanks!

Ole, you can host a .NET control in a Web application, but the client
must have the .NET Framework installed and be using Internet Explorer
5.01+. There's an article discussing how to host .NET controls in a Web
environment at:

Ole,

The alternative is to embed a .NET windows control into IE. However,
this isn't the preferred way of doing this kind of work anymore, because you
really don't gain anything from embedding what is effectively a windows form
in the browser.

Rather, what you should consider is using a "Smart Client" where you can
download the exe from the internet (and run it, it won't require
installation, or minimal installation), which then makes all the calls it
needs through a set of web services.

Hope this helps.

An example of a vector graphics UI implemented as a .NET UserControl, shown
in Internet Explorer:

Notice it runs with the default permissions, in a secure sandbox.

What happened? it was a good idea. but that's all it was. we need a few more
years before that good idea can be translated into a portable, scalable
solution that makes sense in enterprise software.
