Dim startSeqNum As Integer = 1
Dim count As Integer = 5

' ------------------------------------------------------------------------
' The FetchSequenceHeaders method is deprecated:

Dim bundleObj As Chilkat.EmailBundle = imap.FetchSequenceHeaders(startSeqNum,count)
If (imap.LastMethodSuccess = False) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If

' ------------------------------------------------------------------------
' 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 headersOnly As Boolean = True

Dim bundleOut As New Chilkat.EmailBundle
Dim success As Boolean = imap.FetchRange(headersOnly,startSeqNum,count,bundleOut)
If (success = False) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If
