Detect 404 in browser control

[WiseNewbie]

Hey,

Is there a simpler way of detecting a 404 error page occuring inside the WebBrowser control? At the moment i check to make sure the file exists before i browse the page. As you may have figured out this cant work for URLs outside the system. What method/property/function should one use to detect it then?

Thanks!

you could use the inet control to return the source for the page you are trying to view. If the source matches the 404 error page, then the page does not exist.

Doesn't seem like that will work, not every 404 page is the exactly the same html wise.

Also if DNS just plain fails you don't get a 404 back. You get the Page not avialable like if a site was just down.

I think what you want to look at for the Web Browser is

WebBrowser.Body.InnerText

For 404 it seems like 404 is always the first 3 characters. I think that much may be RFC defined but after that it can be different.

For a DNS failure that is something like "Page not Available" and since IE puts that there it should be always the same.

thanks i'll look into these, can we get to the headers of the page request within the IE browser?

that way there may be a sure wya of telling if it was a 404 or not

WiseNewbie have you read FAQ222-2244 yet? Did the status of the webbrowser solve your problem?

Good Luck
