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

imap = chilkat2.Imap()

# Connect to an IMAP server.
# Use TLS
imap.Ssl = True
imap.Port = 993
success = imap.Connect("imap.someMailServer.com")
if (success != True):
    print(imap.LastErrorText)
    sys.exit()

# Login
success = imap.Login("***","***")
if (success != True):
    print(imap.LastErrorText)
    sys.exit()

# Select an IMAP mailbox
success = imap.SelectMailbox("Inbox")
if (success != True):
    print(imap.LastErrorText)
    sys.exit()

# After selecting the mailbox. the total number of emails
# is immediately available:
totalNum = imap.NumMessages
print("Num messages = " + str(totalNum))

# To determine the number of unseen messages, a call
# to Search is required, which returns the set of UIDs
# of all unseen messages.

# We can choose to fetch UIDs or sequence numbers.
fetchUids = True

# messageSet is a CkMessageSet
messageSet = imap.Search("UNSEEN",fetchUids)
if (imap.LastMethodSuccess == False):
    print(imap.LastErrorText)
    sys.exit()

numUnseen = messageSet.Count
print(str(numUnseen))

print("UIDs ----")

# Display the UIDs
i = 0

while i < messageSet.Count :
    msgId = messageSet.GetId(i)
    print(str(msgId))
    i = i + 1

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