Web Application Client Module

[Raffi]

Hi All,

I hope I'm posting this question to the correct newsgroups. We have a
web based database application that's accessed using IE. The
application opens a popup window to run in. With all the popup blockers
and compromised browsers out there, I'm looking into developing a web
based custom client side application to access the application with.
The application will be developed to only reach the web application
site using the https protocol. It also needs to javascript enabled. It
will be downloaded from the main web site and used to access the
database application.

Any suggestions/ideas on how to go about developing the client
application? What tools tools are out there for such a project.

Thanks,
Raffi

This is slightly what I am doing right now, you can use the JavaScript
on the browser to (mainly the XMLHttpRequest object) to access servers
asynchronously, when accessing the server's resource it returns an XML
representation (document) of whatever you want using the browser's
builtin DOM you can parse this and using the same DOM you can modify the
predefined tags or whatever you want. This approach reduces the traffic
to the webserver by only accessing data you need. go to cherrypy.org and
right on the start page there should be a link labeled AJAX which is the
buzzword being used for this kind of implementation.

Hope this helps.

Re: Web Application Client Module

Since you need javascript the cheap-n-dirty approach (xml parser, gui
library of your choice and just enough widget logic/https for your app
to work) is a no-go. I don't know of a python library with html
rendering and javascript (and https support could easily be another
barrier).

Another option starts with Mozilla/Firefox; just strip away all
unnecessary GUI 'features' with a customized XUL. I imagine you could
effectivly hardcode the 'home' URL and make the location bar read-only
without great effort. That will give you HTTPS support, html rendering
and full javascript fairly painlessly.

Course' if your app was designed and tested for IE only you'll have to
wrap the MS rendering/javascript IE libraries. Plenty of commercial
programs do it (AIM and Quickbooks come to mind) but I've never tried
and suspect there are serious licencing hurdles.

It's easy. Just create an application that hosts the MSHTML ActiveX control
(IE itself minus the interface). With tools like Delphi or Visual Basic,
it's literally a matter of dragging and dropping the control into the form.
Even in Visual C++ it's not that hard.

Forcing Javascript to be on is somewhat more tricky. There are a couple COM
interfaces that you to implement.

I suggest you google "MSHTML hosting" for more info. The newsgroup
microsoft.publi c.inetsdk.progr amming.mshtml_h osting is also an excellent
resource.

Thanks for the suggestions. They'll give me the starting point I need.

Third party extensions are not loaded by the MSHTML control, so it wouldn't
be affected by pop-up blockers--or spyware for that matters. WinXP SP2's
popup blocker is controlled by something known as IInternetSecuri tyManager,
whose behavior you can override by implementing your own.

Wouldn't it be easier simply to make it NOT open a pop-up window?
Besides, most browsers usually allow you to whitelist a site, or allow a
single pop-up per click . . .
