' The GetHeaders method is deprecated:

If (mailman.LastMethodSuccess = False) Then
    Debug.WriteLine(mailman.LastErrorText)
    Exit Sub

' Do the equivalent using FetchRange.
' Your application creates a new, empty EmailBundle object which is passed 
' in the last argument and filled upon success.

Dim bundleOut As New Chilkat.EmailBundle
Dim success As Boolean = mailman.FetchRange(keepOnServer,headersOnly,numBodyLines,fromIndex,toIndex,bundleOut)
If (success = False) Then
    Debug.WriteLine(mailman.LastErrorText)
