COM problems again

[this-is-me]

This makes no sense to me. I am getting all kinds of errors that don't seem to have any bearing to what I am doing:

$oMyError = ObjEvent("AutoIt.Error","MyErrFunc"); Install a custom error handler 
Func MyErrFunc() 
   $HexNumber=hex($oMyError.number,8) 
   Msgbox(0,"","We intercepted a COM Error !" & @CRLF & _
               "Number is: " & $HexNumber & @CRLF & _
               "Windescription is: " & $oMyError.windescription ) 

   SetError(1); something to check for when this function returns 
Endfunc

$ie = ObjCreate("InternetExplorer.Application")
$ie.visible = true
$ie.Navigate2("http://windowsupdate.microsoft.com")
While $ie.ReadyState <> 4
    Sleep(250)
WEnd
Sleep(5000)
msgbox(0,"",$ie.frames.length);gives variable must be of type "object"
;msgbox(0,"",$ie.frames.item(0).document.documentElement.innerHTML) ;This one gives some kind of object used outside of a "with" statement or something
;parent.fnScan()

Can someone tell me what I am doing wrong?

I think your trouble is that frames are children of the document object rather than the application object. Try:

msgbox(0,"",$ie.document.frames.length)

Thank you so much dale, I forget that in javascript, anything directly mentioned in the document object or the window does not need to be pre-mentioned.

Another question is how to call a script function in the page. fnScan is a function created in the main html of the page, but I cannot seem to access it with $ie.fnScan() or $ie.document.fnScan(). I can call $ie.document.frames.item("eContent").parent.fnScan() which doesn't error out, but doesn't function either.

Here's another kafuffle, there seems to be a problem with com return values in if statements being assigned instead of compared. See following:

$oMyError = ObjEvent("AutoIt.Error","MyErrFunc"); Install a custom error handler 
Func MyErrFunc() 
   $HexNumber=hex($oMyError.number,8) 
   Msgbox(0,"","We intercepted a COM Error !" & @CRLF & _
               "Number is: " & $HexNumber & @CRLF & _
               "Windescription is: " & $oMyError.windescription ) 

   SetError(1); something to check for when this function returns 
Endfunc

$ie = ObjCreate("InternetExplorer.Application")
$ie.visible = true
$ie.Navigate2("http://windowsupdate.microsoft.com")
While $ie.ReadyState <> 4
    Sleep(250)
WEnd
Sleep(10000)
;MsgBox(0, "", $ie.document.frames("eContent").document.all(0).tagName)
for $i = 0 to $ie.document.frames("eContent").document.all.length
    if $ie.document.frames("eContent").document.all($i).getAttribute("href")="javascript:parent.fnScan();" Then
        MsgBox(0,"", $ie.document.frames("eContent").document.all($i).tagName)
    ;$ie.document.frames("eContent").document.all($i).click()
        ExitLoop
    EndIf
Next
;msgbox(0,"",$ie.frames.item(0).document.documentElement.innerHTML)
;parent.fnScan()

With the above, each and every element in the page has the href assigned to it instead of being compared to it. I think this is one Sven may need to look into as a bug. I will make a duplicate post in the bug reports to bring it up as a current issue.

It appears that AutoIt allows '=' to be used as both an assignment and comparison operator and must make decisions on what to do based on context.

Perhaps you could try '==' as an alternative to see if it makes the correct choice.

Just so you know, I did resort to that, but it also uses == as a literal string, so If there is a difference in capitalization, it would not be a viable solution.

Hello,

I just want to point out at http://www.autoitscript.com/forum/index.php?showtopic=11512 to note for this topic that it's not a bug in COM.

There is a method of the window object called execScript("expression", "lang")

I expected $ie.document.parentwindow.execScript("fnScan();","Javascript") to work but it doesn't. Must have the hierarchy hosed there somewhere. It may be worth playing with however.

Thanks for the heads-up dale. I will look into it.
