Copies an email from one IMAP folder to another. After running this example, copies of the email will be present in both source and destination folders. VB.NET

Dim success As Boolean = False

' 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
success = imap.Connect("imap.example.com")
If (success = False) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


' Login
success = imap.Login("***","***")
If (success = False) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


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


Dim fetchUids As Boolean = True

' Get the message IDs for all emails having "Re:" in the subject.
Dim messageSet As New Chilkat.MessageSet
success = imap.QueryMbx("SUBJECT Re:",fetchUids,messageSet)
If (success = False) 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 = False) 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 = 0
While i < messageSet.Count

    Dim msgId As Integer = messageSet.GetId(i)
    Dim isUid As Boolean = messageSet.HasUids

    success = imap.Copy(msgId,isUid,"Inbox.testing.c")
    If (success = False) Then
        Debug.WriteLine(imap.LastErrorText)
        Exit Sub
    End If

    i = i + 1
End While

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

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