IEnumerator

Remarks

The enumerator can be used manually to enumerate through the values of a list, or it can be wrapped in a custom enumerator to allow it to be used in the For..Each context.

To use an IEnumerator object in For..Each, call the CreateEnumerator method passing in the IEnumerator object. The returned value is then returned in the standard NewEnum(-4) function called by For..Each. The enumeration will then be delegated to the custom IEnumerator object.

Example

 Public Function NewEnum() As IUnknown
     Dim e As New MyEnumerator
     e.Init Me
     Set NewEnum = CreateEnumerator(e)
 End Function
