FullScreen property
Sets or gets a value that indicates whether Windows Internet Explorer is in full-screen mode or normal window mode.
Type: Boolean
One of the values in the Property Values section.
In full-screen mode, the Internet Explorer main window is maximized, and the status bar, toolbar, menu bar, and title bar are hidden.
Setting FullScreen (even to False) resets the values of the AddressBar and ToolBar properties to True. Disable the address bar and toolbars after you set the FullScreen property.
The WebBrowser object saves the value of this property, but otherwise ignores it.
