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

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Imap')
loImap = CreateObject('Chilkat.Imap')

* Connect to an IMAP server.
* Use TLS
loImap.Ssl = 1
loImap.Port = 993
lnSuccess = loImap.Connect("imap.someMailServer.com")
IF (lnSuccess <> 1) THEN
    ? loImap.LastErrorText
    RELEASE loImap
    CANCEL
ENDIF

* Login
lnSuccess = loImap.Login("myLogin","myPassword")
IF (lnSuccess <> 1) THEN
    ? loImap.LastErrorText
    RELEASE loImap
    CANCEL
ENDIF

* Select an IMAP mailbox
lnSuccess = loImap.SelectMailbox("Inbox")
IF (lnSuccess <> 1) THEN
    ? loImap.LastErrorText
    RELEASE loImap
    CANCEL
ENDIF

* We can choose to fetch UIDs or sequence numbers.
lnFetchUids = 1
* Get the message IDs of all the emails in the mailbox
loMessageSet = loImap.Search("ALL",lnFetchUids)
IF (loImap.LastMethodSuccess = 0) THEN
    ? loImap.LastErrorText
    RELEASE loImap
    CANCEL
ENDIF

* Fetch the emails into a bundle object:

loBundle = loImap.FetchBundle(loMessageSet)
IF (loImap.LastMethodSuccess = 0) THEN
    RELEASE loMessageSet
    ? loImap.LastErrorText
    RELEASE loImap
    CANCEL
ENDIF

* To mark a complete set of emails for deletion, call SetFlags:
lnSuccess = loImap.SetFlags(loMessageSet,"Deleted",1)
IF (lnSuccess <> 1) THEN
    ? loImap.LastErrorText
    RELEASE loImap
    CANCEL
ENDIF

* Messages can also be marked for deletion individually:
* Loop over the bundle and mark each message for deletion.
i = 0
lnNumEmails = loBundle.MessageCount
DO WHILE i < lnNumEmails
    loEmail = loBundle.GetEmail(i)
    ? loEmail.From
    ? loEmail.Subject

    * To delete this email, set the "Deleted" flag to 1.
    * The email is not actually deleted until Expunge or
    * ExpungeAndClose is called.
    lnSuccess = loImap.SetMailFlag(loEmail,"Deleted",1)
    IF (lnSuccess <> 1) THEN
        ? loImap.LastErrorText
        RELEASE loImap
        CANCEL
    ENDIF

    ? "--"
    RELEASE loEmail

    i = i + 1
ENDDO

lnSuccess = loImap.ExpungeAndClose()
IF (lnSuccess <> 1) THEN
    ? loImap.LastErrorText
    RELEASE loMessageSet
    RELEASE loBundle
    RELEASE loImap
    CANCEL
ENDIF

* Disconnect from the IMAP server.
lnSuccess = loImap.Disconnect()
