Hi All,

I have never used Intraweb please clarify these questions for me and thanks!
I have someone that has a Delphi app who wants to make it a Web app. In a nutshell, in order to migrate the app what percentage of the task is web enableng the UI? Secondly, he would like to "develop with the evaluation copy till it is time to launch, then buy whatever license is necessary." can this be done or will there be constraints in the evaluation version.
Lastly, for the unbiased. If this is being written from scratch am I better off with .net?

Thanks again!

You have to rebuild your forms using IW forms and controls, but in many
cases, depending on how your app is written, you can reuse a lot of
your code from the windows app. Also, if you intend to have your web
app used by thousands of simultaneous users, then you will probably
need to rethink your approach a bit to make the app as scalable as
possible. If not, then you can likely continue to use the normal
form/datamodule mindset of a desktop app.

I don't know if there are licensing problems with doing that, since the
eval is exactly that, an eval... but having said that, the only
restrictions you will see are deployment issues. They will be fairly
transparent during the development process.

If you had to write it from scratch, and you are expecting to have an
end product that resembles your desktop app at all, then you are better
off sticking with IW. You will have to learn a whole lot less and
porting your existing stuff will be easier for sure.

Personally I would stick with IW, especially in your case wherein you
already have a Desktop App and just want to migrate to web.
as Jason has said you may have to recreate your forms in IW but the
underlyin code can be copy pasted.

Think of it as switching each form to an IW form - most (probably all)
of your UI components like edit boxes, comboboxes, etc will have their
counterpart in the Intraweb component pallette. Also, if you are using
a datamodule, those components will be moved to IW's usersession
(tables,session and query components) and servercontroller (your db's
client server connection components or the embedded server component).

I believe the port address changes randomly, each time the app is
started with eval copy - no big deal during development.

For migrating a Delphi app to the web, Intraweb is the best choice!
