Lianja Requires Chilkat v11.0.0+

Mark IMAP Email as Read/Unread (Seen/Unseen)

Demonstrates how to mark emails as read or unread. Lianja

llSuccess = .F.

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

loImap = createobject("CkImap")

//  Connect to an IMAP server.
//  Use TLS
loImap.Ssl = .T.
loImap.Port = 993
llSuccess = loImap.Connect("imap.example.com")
if (llSuccess = .F.) then
    ? loImap.LastErrorText
    release loImap
    return
endif

//  Login
llSuccess = loImap.Login("myLogin","myPassword")
if (llSuccess = .F.) then
    ? loImap.LastErrorText
    release loImap
    return
endif

//  Select an IMAP mailbox
llSuccess = loImap.SelectMailbox("Inbox")
if (llSuccess = .F.) then
    ? loImap.LastErrorText
    release loImap
    return
endif

//  Set PeekMode so that downloaded messages are not
//  automatically marked as seen.
loImap.PeekMode = .T.

//  The NumMessages property contains the number of messages 
//  in the currently selected mailbox.
lnNumMsgs = loImap.NumMessages
if (lnNumMsgs = 0) then
    release loImap
    return
endif

loEmail = createobject("CkEmail")

for i = 1 to lnNumMsgs
    //  Download each email by sequence number (not UID)
    llSuccess = loImap.FetchEmail(.F.,i,.F.,loEmail)
    if (llSuccess = .F.) then
        ? loImap.LastErrorText
        release loImap
        release loEmail
        return
    endif

    //  If desired, mark the email as SEEN.  There are two
    //  ways to do it:

    //  1) Set the flag directly by using the sequence number
    //  Indicate that we are passing a sequence number and
    //  not a UID:
    llBIsUid = .F.
    //  Set the SEEN flag = 1 to mark the email as SEEN,
    //  or set it to 0 to mark it as not-seen.
    llSuccess = loImap.SetFlag(i,llBIsUid,"SEEN",1)
    if (llSuccess = .F.) then
        ? loImap.LastErrorText
        release loImap
        release loEmail
        return
    endif

    //  2) Alternatively, we can use the email object.
    //  When an email is downloaded from the IMAP server
    //  Chilkat will add a "ckx-imap-uid" header to the email.
    //  This makes it possible to know the UID associated with
    //  the email.  (This is not the sequence number, which may change
    //  from session to session, but the UID which does not change.
    //  The SetMailFlag method is identical to SetFlag, except
    //  it gets the UID from the ckx-imap-uid header.
    //  For example:
    llSuccess = loImap.SetMailFlag(loEmail,"SEEN",1)
    if (llSuccess = .F.) then
        ? loImap.LastErrorText
        release loImap
        release loEmail
        return
    endif

next

//  Disconnect from the IMAP server.
llSuccess = loImap.Disconnect()
