* This example requires 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')
loImapSrc = CreateObject('Chilkat.Imap')

* Connect to our source IMAP server.
lnSuccess = loImapSrc.Connect("imap.someMailServer.com")
IF (lnSuccess <> 1) THEN
    ? loImapSrc.LastErrorText
    RELEASE loImapSrc
    CANCEL
ENDIF

* Login to the source IMAP server
lnSuccess = loImapSrc.Login("admin@chilkatsoft.com","myPassword")
IF (lnSuccess <> 1) THEN
    ? loImapSrc.LastErrorText
    RELEASE loImapSrc
    CANCEL
ENDIF

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

* Connect to our destination IMAP server.
lnSuccess = loImapDest.Connect("mail.example-code.com")
IF (lnSuccess <> 1) THEN
    ? loImapDest.LastErrorText
    RELEASE loImapSrc
    RELEASE loImapDest
    CANCEL
ENDIF

* Login to the destination IMAP server
lnSuccess = loImapDest.Login("myLogin","myPassword")
IF (lnSuccess <> 1) THEN
    ? loImapDest.LastErrorText
    RELEASE loImapSrc
    RELEASE loImapDest
    CANCEL
ENDIF

* Select an IMAP mailbox on the source IMAP server
lnSuccess = loImapSrc.SelectMailbox("Inbox")
IF (lnSuccess <> 1) THEN
    ? loImapSrc.LastErrorText
    RELEASE loImapSrc
    RELEASE loImapDest
    CANCEL
ENDIF

* After selecting a mailbox, the NumMessages property will
* be updated to reflect the total number of emails in the mailbox:
? STR(loImapSrc.NumMessages)

* The emails in the mailbox will always have sequence numbers
* ranging from 1 to NumMessages.

* This example will copy the first 10 messages.
* We'll leave it up to you to write code to copy
* the entire sequence range in reasonable size chunks.
lnStartSeqNum = 1
lnMsgCount = 10

loSa = loImapSrc.FetchSequenceAsMime(lnStartSeqNum,lnMsgCount)
IF (loImapSrc.LastMethodSuccess <> 1) THEN
    ? loImapSrc.LastErrorText
    RELEASE loImapSrc
    RELEASE loImapDest
    CANCEL
ENDIF

FOR i = 0 TO loSa.Count - 1
    lnSuccess = loImapDest.AppendMime("Inbox",loSa.GetString(i))
    IF (lnSuccess <> 1) THEN
        ? loImapDest.LastErrorText
        RELEASE loImapSrc
        RELEASE loImapDest
        CANCEL
    ENDIF

RELEASE loSa

* Disconnect from the IMAP servers.
lnSuccess = loImapSrc.Disconnect()
lnSuccess = loImapDest.Disconnect()
