vbHidden

• Indicates that the file is a hidden file for file-access functions.
• Namespace: Microsoft.VisualBasic
• Assembly: Microsoft.VisualBasic (in Microsoft.VisualBasic.dll)
• Declaration : Public Const vbHidden As FileAttribute
• When you call the Dir, GetAttr, or SetAttr functions, you can use the FileAttribute enumeration in your code in place of the actual values.
• The Attributes argument takes the FileAttribute enumeration members.
• When performing file I/O operations, the My.Computer.FileSystem object provides greater performance and ease of use than legacy file I/O methods.

Windows.Visibility.Hidden

• Specifies the display state of an element.
• Namespace: System.Windows
• Assembly: PresentationCore (in PresentationCore.dll)
• **Declaration:**Public Enumeration Visibility.

• Elements that have a Visibility value of Collapsed do not occupy any layout space. By default, elements are Visible.

  ---MEMBERS---

• Collapsed: Do not display the element, and do not reserve space for it in layout.
• Hidden: Do not display the element, but reserve space for the element in layout.
• Visible: Display the element.
