Automation error when getting ReadyState of InternetExplorer object

Question

I get two different errors on the same line. Sometimes this one:

Automation error: object invoked has disconnected from its clients

Answer 1

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.
