' * Comments         : This class is an easy, self-contained way to get
' *  complete access to the Windows registry.
' *  Simple methods allow you to create, enumerate and delete keys
' *  and values in the registry, without restriction.
' *  You can even read/write binary data to the registry.
' *
' * Example :
' *  get a String Value from the Registry
' *    Dim clsRegistry As New class_Registry
' *    With clsRegistry
' *       .ClassKey = HKEY_LOCAL_MACHINE
' *       .SectionKey = "Software\PrintPreview"
' *       .ValueKey = "Version"
' *       .ValueType = REG_SZ
' *       sTip = .Value
' *    End With
' *
' *  Save a Form's position to the Registry
' *    Dim clsRegistry As New class_Registry
' *    With clsRegistry
' *       .ClassKey = HKEY_CURRENT_USER
' *       ' You don't need to check if this key already exists
' *       ' - the class will create it for you
' *       .SectionKey = "Software\" & App.EXEName & "\" & frmThis.name
' *       .ValueKey = "Maximized"
' *       .ValueType = REG_DWORD
' *       .Value = (frmThis.WindowState = vbMaximized)
' *       If (frmThis.WindowState <> vbMaximized)
' *           .ValueKey = "Left"
' *           .Value = frmThis.Left
' *           .ValueKey = "Top"
' *           .Value = frmThis.Top
' *           .ValueKey = "Width"
' *           .Value = frmThis.Width
