Answer 1

I had the same Run time error 70. Permission denied when automating a Webbrowser control in VBA under MS Access 2010. My objective was to set innerHTML for a Content Editable node. Initially, it worked perfectly and then for an unknown reason, I started getting "Error 70. Permission Denied." Interestingly, this error seems to come from the IE Web Browser control and not from MS Access. At times, it was not trapped by the VBA error handler, On Error. Another puzzle is that when single stepping through the code, it would work, but when running normally, the Webbrowser control would just not function, but not raise an error. However, it would raise an error if I set a break point and then queried the WebBrowser in the immediate pane on VBA with code such as: ? DIV.innerHTML

Here is the code that failed:

Private Function SetInnerHTML(HTML As String) As String
Dim HTMLEmail As HTMLDocument
Dim DIV As HTMLDivElement
Set HTMLEmail = Me.Email_MainBrowser.Controls("MyBrowser").Object.Document
Set DIV = HTMLEmail.getElementById("MyText")
DIV.innerHTML = HTML ' This is the line that failed

Like Dennis, the OP, I tried adding in Sleep calls and added in function calls to make sure the Browser returned "Ready State" CurrentState = Me.Form("Email_MainBrowser").Controls("MyBrowser").ReadyState (CurrentState should be acComplete).

Here are the things I tried which did not solve the problem: 1) Decompile and recompile the MS Access application. 2) Add calls to Win32 sleep function to wait for the WebBrowser control 3) Queried the Webbrowser to make sure it was in a Navigation Complete state.

And here is what fixed it: Added "DoEvents" liberally around the code referencing and automating the webbrowser control:

Dim HTMLEmail As HTMLDocument
Dim DIV As HTMLDivElement
DoEvents
Set HTMLEmail = Me.Email_MainBrowser.Controls("MyBrowser").Object.Document
Set DIV = HTMLEmail.getElementById("MyText")
DoEvents
DIV.innerHTML = HTML
DoEvents

I have not worked out the minimum number of DoEvents needed; it is probably just one strategically placed. I also still check to make sure the webbrowser control is in the Natigation complete state, but I'm sure this is a bug deep in the Webbrowser control. One that will probably never be fixed.

Try this code for me. This bypasses the need to select/click any element in the browser.

I tested this for INDIA

Sub Sample1() '<~~ Works as expected
    Dim IE As New InternetExplorer
    IE.Visible = True
    IE.Navigate ("http://www.google.co.in/#hl=en&q=" & "Search Term")
End Sub

For UK

Sub Sample2() '<~~ Works as expected
    Dim IE As New InternetExplorer
    IE.Visible = True
    IE.Navigate ("http://www.google.co.uk/#hl=en&q=" & "Search Term")
End Sub

Try this for US (Couldn't Test It as it redirects my request)

Sub Sample3()
    Dim IE As New InternetExplorer
    IE.Visible = True
    IE.Navigate ("http://www.google.com/#hl=en&q=" & "Search Term")
End Sub

Answer 3

The following worked for me. I haven't tested it extensively, but the problem hasn't recurred. I was getting the error intermittently, but always at same point.

Control of the first IE instance seems to die. However, another instance can be created by referencing the first. The dead instance can then be closed, and we carry on.

Set IEa = CreateObject("InternetExplorer.Application")
Set IEa = IE
   'Where IE is the instance that's about to error
SendKeys ("%{F4}")
   'Closes the old window, IE.quit in the code wouldn't work
IEa.Visible = True

Hope this works for someone else, I was getting pretty frustrated.

Answer 4

I am receiving the same error when automating IE, but instead of fixing, I worked around.

  Label1:
         If myIe Is Nothing Then
             Set myIe = CreateObject("InternetExplorer.Application") 
         End If

         myIe.Navigate URL:=imdbLink

    For Each link In myIe.document.Links
         If Right(link.href, 9) = "/keywords" And Left(link.href, 26) = "http://www.imdb.com/title/" Then
                    mKPlot = link.href 'ERROR GENERATES FROM THIS, SOMETIMES...
         End If
    next link



errHandler:
    If Err.Number = 70 Then
        Debug.Print "permission denied for: |" & title & "|"

        myIe.Quit
        Set myIe = Nothing

        Application.Wait Now + TimeValue("00:00:10")

        Resume Label1:

    End If

Not the sleek registry-fix you were imagining, but it works for me.

Answer 5

This is a common issue with Internet Explorer automation in VBA. It generally seems to happen after a new page has been loaded. I have had success using a combination of DoEvents, Application.Wait, and setting my HTMLDocument object to Nothing after a new page load.

I have posed sample code below to demonstrate:

Option Explicit

Sub IEAutomation()

    Dim IE As InternetExplorer
    Dim html As HTMLDocument
    Dim i As HTMLHtmlElement
    Dim search_bar_id As String
    Dim submit_button_name As String
    Dim search_term As String

    'Define Variables
    search_bar_id = "lst-ib"
    submit_button_name = "btnK"
    search_term = "Learning VBA"

    'Create IE and Naviagate to Google
    Set IE = CreateObject("InternetExplorer.Application") 'Late Binding
    IE.Visible = True
    IE.navigate "http://www.google.com"

    'Wait for IE To Load
    Do While IE.readyState <> READYSTATE_COMPLETE: DoEvents: Loop

    'Create HTMLDocument Object
    Set html = IE.document

    'Enter Search Term into Search Bar and Click Submit Button
    html.getElementById(search_bar_id).innerText = search_term
    Application.Wait Now + TimeValue("0:00:01")
    html.getElementsByName(submit_button_name)(, 1).Click

    'Wait for New Page to Load (** DoEvents Helps with the Permission Issue **)
    Do While IE.readyState <> READYSTATE_COMPLETE: DoEvents: Loop

    'After Page Loads, Reset HTMLDocument Object and Wait 1 Second Before Recreating It
    Set html = Nothing
    Application.Wait Now + TimeValue("0:00:01") '<<< This seems to really help
    Set html = IE.document

    'Print All Elements In H3 Tags to Immediate Window in VBE
    For Each i In html.getElementsByTagName("H3")
        Debug.Print i.innerText
    Next i

End Sub

Answer 6

I was having this exact same problem. Had a script for automating IE that had been working fine for a year. Then out of the blue I started receiving this "permission denied error". I did two things, one of which fixed the problem, but I don't know which one.

1. I removed the reference to "Microsoft Internet Controls", attempted to compile the project, added the reference to "Internet Controls" back in, and compiled the project.

2. Removed the 'WithEvents' keyword when declaring the InternetExplorer object since I did not need to capture events events from IE anyway.

I suspect it was the first and that somehow the reference became corrupted and removing at and re-adding it fixed the problem.
