Determinine IE.Navigate2 Status

I am trying to automate the daily morning system checks. Part of the
items to check is a bunch of URL's. I have a script that opens them
all in a new window for manual verification. It seems possible but I
can't figure out how to determine the status of the recently navigated
url. Is there anyway way to use .NavigateError or some other method to
determine if a 404 error type is the result of the navigate function?

Speaking from abject ignorance, I doubt it. IE doesn't fail. It loads a page at
the specified URL. It just isn't the page you want. The only way I can think of
would be to read the page contents and determine what is on it. Something like
this:

if instr(IE.document.body.innerText,"HTTP 40") then msgbox "Navigation error!"

This is risky because not all error pages are the same and some server
administrators like to get "cute" with their error messages. If all the morning
URL's are on a constant and controlled system, like a LAN, you should be OK.

I thought about a text stream read but wasn't sure how that would work
or read the window title that should indicate "Page Not Found". Thanks.

How do you invoke IE.document in your example? For example I have
CreateObject("InternetExplorer.Application") and as best I can tell
.Document is at the same level as Application, do I need to create a
second object for InternetExplorer.Document?

How are you checking the URL's? Don't you have to "navigate" to them?

Set IE = CreateObject("InternetExplorer.Application")
IE.Navigate "http://hal9000/nada.htm"
do until IE.readyState = 4 : wscript.sleep 10 : loop
if instr(IE.document.body.innerText,"HTTP 40") then msgbox "Navigation error!"

Note that this works with default error pages on an IIS server, but didn't work
on an Apache server because the error text didn't contain the string I search
for. It will have to be tailored for your situation.

NavigateError is an event that occurs on HTTP-errors, like 404.
It also tells you the errorcode, anything but 200 is error.


set ie = wscript.createobject("internetexplorer.application", "ie_")
ie.Navigate "http://www.cnn.com/iunknown.nodispatch.aspx"
ie.Visible = true


While 1 : WSH.Sleep 1000 : Wend


Sub ie_NavigateError(pDisp, URL, TargetFrameName, _
StatusCode, ByRef Cancel)

WSH.Echo "NavigateError, url: ", URL, vbcr & _
"StatusCode:", StatusCode

End Sub

Sub ie_Quit
WSH.Quit
End Sub

Neat! I didn't know server errors were detectable. Thanks.
