The InPrivate property returns whether the browser session
is using private (incognito) browsing. If this property is True, the
user profile is not persisted beyond the current session. Browsing and
search history will not be preserved, all cookies are temporary, data
entered in form fields will not be saved and passwords will not be
stored. If the DataFolder property has been set to specify a
folder path for the session profile, setting this property to True
will cause the control to create a unique, temporary folder in that
location. Any general location information used by the browser is
cleared when the application is closed.
This property can only be set in design mode or from within the
Initialize event. After an instance of the browser is created,
attempting to change this property will result in an error.
