Advert Blocker...

[Miles_rich]

You know when you load a web page and you get adverts that are displayed at the sides or at the top like a banner, how would you parse the html before it loads into IE 6 and change images to txt saying something like [AD BLOCKED] ???

does anyone have any ides becuase i have been trying to work out how programs like outpost firewall and other firewalls do it.

dear,

if you use the microsoft internet transfer control, you can open an internet url and parse the data into a string, then search the string for e.g. adrotator

inetDC.Proxy = "your-proxy:8080"
  inetDC.AccessType = icNamedProxy
  strString = Replace(inetDC.OpenURL("http://...", icString), Chr(10), vbCrLf)
  strString = Replace(strString, ...

but the problem is, that banners are often simple images, and you cannot distinguish them from "normal" page images

hope this helps a little,

so i would have to create a proxy aswell? i dont fully understand your code, could you please explain a bit more in detail, or maybe you could email and we could discuss this further.

dear,

a short explanation on the code:

if you use the microsoft internet transfer control (attach it to your project components, then you receive a control called Inet, put that on a form - in my example i have called it inetDC)

in the form_load event you define which proxy server should be used for internet communication by:

inetDC.Proxy = "your-proxy:8080"
inetDC.AccessType = icNamedProxy

if you don't use/have a proxy, but direct connection to the internet, you use

inetDC.AccessType = icDirect

or

inetDC.AccessType = icUseDefault

(then the registry settings will be used)

then you may access a web site, e.g. my homepage www.big-nell.com by:

strString = inetDC.OpenURL("http://www.big-nell.com", icString)

the content of the page will be passed to the variable strString
after that you can search for html-tags you want to be replaced

strString = Replace(strString, ...

but as i mentioned, the problem is, that banners are often simple images, and you cannot distinguish them from "normal" page images

if you have questions, send a mail ([email protected])

kind regards,
big nell
