No Help Topic for the Following Error Messages
----------------------------------------------

There are currently no Help topics for the following error messages:

- "Object module needs to implement '<name>' for interface
  '<classname>'."

An interface is a collection of unimplemented procedure prototypes. This error
occurs when you specified an interface in an Implements statement, but you
failed to add code for all the procedures in the interface.

You must write code for all procedures specified in the interface. An empty
procedure containing only a comment is sufficient.

For additional information, select the item in question and press F1.

- "Private Enum types and Enum types defined in standard modules or private
  classes cannot be used in public object modules as parameters or return types
  for public procedures, as public data members, or as fields of public user
  defined types."

This error occurs when you attempt to use an Enum type (or private Enum type)
as:

- A parameter for a public object module

- A return type for a public procedure

- A public data member

- Fields of public user-defined types

Avoid using Enum or private Enum types in these circumstances.

- "Can't ReDim, Erase, or assign to Variant that contains array whose element
  is With object."

This error occurs when you attempt to ReDim, Erase, or assign to a Variant a
variable whose element is a With object. For example, the following code will
produce this error:

     Type Test
        Name as Integer
     End Type

     Sub Main()
        Dim c(0) As Test
        Dim e
        e = c
        With e(0)
           ReDim e(1)
        End With
     End Sub
