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

' This example copies an email from one mailbox to another.
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("***","***")
If (success <> True) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


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


Dim messageSet As Chilkat.MessageSet
Dim fetchUids As Boolean = True

' Get the message IDs for all emails having "Re:" in the subject.
messageSet = imap.Search("SUBJECT Re:",fetchUids)
If (imap.LastMethodSuccess <> True) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


' Copy the messages from "Inbox.testing.a" to "Inbox.testing.b" in one call to CopyMultiple:
success = imap.CopyMultiple(messageSet,"Inbox.testing.b")
If (success <> True) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


' Alternatively, loop over each message in the set and
' copy each separately:
Dim i As Integer
Dim n As Integer
n = messageSet.Count
If (n > 0) Then
    For i = 0 To n - 1
        Dim msgId As Integer = messageSet.GetId(i)
        Dim isUid As Boolean = messageSet.HasUids
        success = imap.Copy(msgId,isUid,"Inbox.testing.c")
        If (success <> True) Then
            Debug.WriteLine(imap.LastErrorText)
            Exit Sub
        End If

    Next
End If


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

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