Internet Explorer 8. On Windows Vista,

to create an instance of Internet Explorer

running at a medium integrity level,

pass CLSID_InternetExplorerMedium (defined in ) to CoCreateInstance. The

resulting InternetExplorerMedium object supports the same events, methods, and

properties as the InternetExplorer object.

Examples

The following example

Visual uses CreateObject in

Explorer.

Dim IE As etExplorer

Set IE = CreateObject("ation")

The following C# example launches an

Microsoft

Basic to launch an instance of Internet

instance of Internet Explorer and navigates

to a Web page. The code also
