' The CheckForNewEmail method is deprecated:

Dim msgSetObj As Chilkat.MessageSet = imap.CheckForNewEmail()
If (imap.LastMethodSuccess = False) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If

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

Dim criteria As String = "new-email"
Dim bUid As Boolean = True

Dim msgSet As New Chilkat.MessageSet
Dim success As Boolean = imap.QueryMbx(criteria,bUid,msgSet)
If (success = False) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If
