Application for people with disabilities x WebBrowser component

Hi friends,

First of all, sorry for my limited english. I'll do my best. ;)
Huge, huge problems, directly from Brazil... :|

I'm working on a VB.NET application for disabled people which uses the WebBrowser control to capture the HTML content from an webpage (just to present, after some code treatment, in a textbox) and trying to solve the following three problems:

1) I'm using the WebBrowser control just to load a web page, but some pages provide a refresh after some minutes. Is it possible to avoid/disable the WebBrowser refresh (important: I need to keep the WebBrowser instance alive, so I can simply dispose it) or I'll have to rewrite my application to use WebClient control instead? (solution that will be provide much more work in my case).

2) The DocumentCompleted event, that takes the HTML content and shows in the textbox, is called several times for some pages (like www.uol.com.br) and obviously beginning to execute the code on my sub method several times too. A friends of mine tell me that maybe it can be solved "setting the WebBrowser for HTTP 1.0 to avoid the load from Ajax content". Is there anyone who knows how to do it or simply knows a way/event more precise?

3) Is it possible to take the HTML content and convert the charset "on the fly"? If not, anyone knows an URL with a sample code?

Thanks very very very very very very much for any help, that will be really
precious to me and my friends.

Hugs from Brazil,
Alexandre.

If you capture it first, you can do whatever you want with it, BEFORE loading it into your WB control, I'd think.


You might also look at IE8 as a display mechanism. It includes some amazing improvements in zooming, and other features for the visually impaired

Hi dglienna... Thank you very much for your time. An other forum's friend sent me a solution to the problem number 2 (envolving the DocumentCompleted event). Now I'm trying to find a way to stop the page refreshs and show the page with the right encoding.

Important: I can't use the IE8 display mechanism because my application needs to capture and improve the content for a specific kind of impaired user...

Thank you again!
