_IELinkDownloadByText ?

2 posts in this topic

Would it be possible to write a function similar to _IELinkClickByText, only have it save the file, simulating the "Save Link As" menu? The only reason I ask this? Unfortunately, in my particular case, INetGet will not work and neither will _IEAction("SaveAs").

I've searched through these forums and noted that IE has security against scripting downloading of files, but I wondered if anyone has had success (in AutoIt or otherwise) with the ExecWB command.

Here's what I started (i.e., copied/modified):

Func _IELinkDownloadByText(ByRef $o_object, $s_linkText, $i_index = 0, $f_wait = 1)
   If Not IsObj($o_object) Then
      __IEErrorNotify ("Error", "_IELinkClickByText", "$_IEStatus_InvalidDataType")
      SetError($_IEStatus_InvalidDataType, 1)
      Return 0
   EndIf
   ;
   Local $found = 0, $link, $linktext, $links = $o_object.document.Links
   $i_index = Number($i_index)
   For $link In $links
      $linktext = $link.OuterText & "" ; Append empty string to prevent problem with no outerText (image) links
      If $linktext = $s_linkText Then
         If ($found = $i_index) Then
            $o_object.ExecWB ("SaveAs", 1, $link, "")
            If $f_wait Then
               _IELoadWait($o_object)
               SetError(@error)
               Return -1
            EndIf
            SetError($_IEStatus_Success)
            Return -1
         EndIf
         $found = $found + 1
      EndIf
   Next
   __IEErrorNotify ("Warning", "_IELinkClickByText", "$_IEStatus_NoMatch")
   SetError($_IEStatus_NoMatch) ; Could be caused by parameter 2, 3 or both
   Return 0
EndFunc

Returns:

C:\...\Solix_Web.au3 (33) : ==> The requested action with this object has failed.: 
$o_object.ExecWB ("SaveAs", 1, $link, "") 
$o_object.ExecWB ("SaveAs", 1, $link, "")^ ERROR

I know my syntax on ExecWB is wrong, but I'm not clear how it's used, even after looking on MSDN and Googling other sites.

I'm thinking I'm at a dead end, but thought I'd ask, just in case anyone has any ideas.

Thanks!

You are at a dead end with that approach. Been there, tried that.

_IEAction($oIE, "saveas") executes $oIE.document.execCommand("SaveAs"), which is in reality just an interface to ExecWB("saveAs") - the same command you are trying to use. This ExecWB("saveAs") actually has a documented parameter that is stated to allow saving without a file dialog, but it was disabled in IE a long time ago -- references you find to it are either very old or misguided. This feature was viewed as a security flaw (in all browsers) and I think you can see that if there was another way to do it through browser script it would certainly have been exploited and then fixed as well.

You can work around this with AutoIt however by activating the File SaveAs dialog and then using WinActivate and Send (or ControlSend) functions to automate the dialog.
