' This example requires the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

Dim imap As New Chilkat.Imap

' Turn on session logging:
imap.KeepSessionLog = True

' Connect to an IMAP server.
' Use TLS
imap.Ssl = True
imap.Port = 993
Dim success As Boolean = imap.Connect("imap.someMailServer.com")
If (success <> True) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


' Login
success = imap.Login("myLogin","myPassword")
If (success <> True) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


' Select an IMAP mailbox
success = imap.SelectMailbox("Inbox.RubyMail")
If (success <> True) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If



Dim messageSet As Chilkat.MessageSet

' Get the complete set of Uids for email in the selected mailbox.
messageSet = imap.GetAllUids()
If (imap.LastMethodSuccess <> True) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


' Set the Deleted flag for each message.
' (ExpungeAndClose must be called to finalize the delete.)
success = imap.SetFlags(messageSet,"Deleted",1)
If (success <> True) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If



' Alternatively, the Deleted flag may be set for each UID
' individiually, but this is less efficient:
Dim i As Integer
Dim n As Integer = messageSet.Count
For i = 0 To n - 1
    success = imap.SetFlag(messageSet.GetId(i),messageSet.HasUids,"Deleted",1)
    If (success <> True) Then
        Debug.WriteLine(imap.LastErrorText)
        Exit Sub
    End If

Next

' Expunge and close the mailbox.
success = imap.ExpungeAndClose()
If (success <> True) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


' Display the session log.
Debug.WriteLine(imap.SessionLog)

' Disconnect from the IMAP server.
success = imap.Disconnect()
