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
