Can someone please explain to me if there is a difference between
Set objIE = CreateObject("internetexplorer.application")
and
Set objIE = New InternetExplorer
The first one is late binding, and the second one is early binding. Early binding also requires a reference in the project whereas late binding does not.

I have managed to get my code to work, but only by searching the internet and finding something that worked, I don't actually understand why.
Could someone please explain why when I used
Dim IE As New InternetExplorer
trying to press a button gave me the error
Object invoked has disconnected from clients
but using
Dim ie As SHDocVw.InternetExplorer
has worked?
Thank You
You are trying to do early binding of IE in VBA. Thus, you need to do it like this:
Dim ie As SHDocVw.InternetExplorer or Dim IE As New InternetExplorer, after adding the "Microsoft Internet Controls" library to the project (c:\windows\syswow64\ieframe.dll).
In general, if you want to do late binding, you should do it like this:
Dim IE As Object
Set IE = CreateObject("InternetExplorer.Application")
What is the difference between Early and Late Binding? and my understanding about late and early binding
I am just starting to learn Internet Explorer Automation using VBA and I am facing an issue.
The Document object is empty which prevents me from going further than just loading a page. I have been looking around the net for a solution to this and could not find anything working so here I am, asking for your help.
NB: My VBA level is intermediate
Windows 8.1 pro 64 bit
I wrote an example code
I had a the same issue (nothing in the .document) , with Internet Explorer 11.
I had to add the site to the Compatibility View list (gear, compatibility view, add)
Hopefully this will help someone avoid the time I spent looking for a solution.
This code works for me. It uses a loop to wait until navigation is complete.
Sub NavigateGoogle()
Dim i As Long
Dim ie As InternetExplorer
Dim Googledoc As HTMLDocument
Set ie = CreateObject("InternetExplorer.Application")
ie.Visible = True
ie.navigate "www.google.com"
Do
DoEvents
Loop While ie.Busy
Set Googledoc = ie.document
Debug.Print Googledoc.all(0).innerHTML
Set ie = Nothing
End Sub
I try to get the DOM from VBA with access. But I can't get the DOM.
Dim objHTML As Object
With IE
.Navigate2 "http://myanimelist.net/animelist/Alaanor"
WaitIE
Set objHTML = .Document.body.innerHTML
End With
But I have read the documentation of IE.Document and he said:
Warning If the document object type is not marked safe for scripting, this property returns Nothing.
That exactly the problem I have. But I can't find how solve it.
Anyone can help me ?
I get two different errors on the same line. Sometimes this one:
Automation error: object invoked has disconnected from its clients
and sometimes:
the interface is unknown
Minimal code to reproduce error:
Sub mcve()
Dim ie As Object
Dim www As String
Set ie = New InternetExplorerMedium
www = "http://www.stackoverflow.com"
ie.navigate www
ie.Visible = False
While ie.ReadyState <> 4 ' <~~~~~~~~~~~~~~~~~~~~~~~~ Error occurs here
DoEvents
Wend
End Sub
This requires a reference: Tools > References... > Microsoft Internet Controls
The error occurs on While ie.ReadyState <> 4 the second time. How do I fix this?
This is a duplicate of a previously asked question. The problem seems to be caused by Internet Explorer security settings - when switching between security zones, the current instance of IE is killed and a new instance is created, so your reference to the old process is no longer valid.
Some of the suggested solutions were:
Change IE security settings. Uncheck "enable protected mode" on the Security tab of Internet Options.
Navigate to the IP address directly instead of the URL. This is the one that fixed it for me. For example, ie.navigate "64.233.177.106" (Google's IP address)
Set ie = New InternetExplorerMedium instead of New InternetExplorer. Or in your case, vice versa.
Instead of
Set ie = New InternetExplorerMedium
just use
Set ie = New InternetExplorer
or, for late binding:
Set ie = CreateObject("InternetExplorer.Application")
This makes the error go away.
I'm not sure why you would use InternetExplorerMedium in the first place. Quoting the small print in the documentation:
Remarks
Windows Internet Explorer 8. On Windows Vista, to create an instance of Internet Explorer running at a medium integrity level, pass CLSID_InternetExplorerMedium (defined in exdisp.idl) to CoCreateInstance. The resulting InternetExplorerMedium object supports the same events, methods, and properties as the InternetExplorer object.
Are you really using IE8 on Windows Vista, and do you really want "medium integrity level", whatever that means? I didn't think so.
Open Internet Explorer, then, go to internet settings, open "Sites" ande clear the web page that need the server comprobation. The problema is for the server comprobation.
Say I created a program with a textbox on it and a button that does something with the text in the textbox.
How do I make that program COM visible, load it and automate it from another project?
My goal is to be able to automate the program using COM:
Dim myProj as object = createObject("myProgram")
myProj.setText("Hello World")
myProj.buttonClickEvent()
Similar to how you can load a new excel and automate via interop:
dim xl as object = createobject("excel.application")
Dim wb as object = xl.workbooks.add
Dim ws as object = wb.worksheets(1)
ws.cells(1,1) = "i love stackoverflow"
How do programs do this? I'm looking for the answer VB.Net specific. Thank you in advance!
This page should give you the necessary details you will need: http://www.codeproject.com/KB/vb/MusaExposingCOM.aspx
This process that you want is normally called "exposing a COM interface", this is done via early binding or late binding. Early binding means the methods (locations) are known when you create your program, late binding means the methods (locations) are looked up when you run the program. Late binding, I think, is a little slower but the lookup only has to happen once. This is negligible.
