Exception
Description
Attachmate.Reflection.SecuredSettingException
This exception is thrown when you modify a property that was secured via
the Permissions Manager, or that can only be modified by an Administrator.
Remarks
The two options include Block and Stream. Block causes the selected text to form a rectangle. Stream causes the selection to flow from one row to another, the same way that text wraps.
