require 'chilkat'

success = false

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

imap = Chilkat::CkImap.new()

# Connect to the IMAP server.
# Use TLS
imap.put_Ssl(true)
imap.put_Port(993)
success = imap.Connect("imap.someMailServer.com")
if (success == false)
    print imap.lastErrorText() + "\n";
    exit
end

# Login
success = imap.Login("myLogin","myPassword")
if (success == false)
    print imap.lastErrorText() + "\n";
    exit
end

# Select an IMAP mailbox
success = imap.SelectMailbox("Inbox")
if (success == false)
    print imap.lastErrorText() + "\n";
    exit
end

fetchUids = true
messageSet = Chilkat::CkMessageSet.new()
success = imap.QueryMbx("ALL",fetchUids,messageSet)
if (success == false)
    print imap.lastErrorText() + "\n";
    exit
end

# Fetch the email headers into a bundle object:
bundle = Chilkat::CkEmailBundle.new()
headersOnly = true
success = imap.FetchMsgSet(headersOnly,messageSet,bundle)
if (success == false)
    print imap.lastErrorText() + "\n";
    exit
end

# Sort the email bundle by date, recipient, sender, or subject:
ascending = true
bundle.SortByDate(ascending)

# To sort by recipient, sender, or subject, call 
# SortBySender, SortByRecipient, or SortBySubject.

# Display the Subject and From of each email.
email = Chilkat::CkEmail.new()
i = 0
while i < bundle.get_MessageCount()
    bundle.EmailAt(i,email)

    print email.getHeaderField("Date") + "\n";
    print email.subject() + "\n";
    print email.ck_from() + "\n";
    print "--" + "\n";

    i = i + 1
end

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