' 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")
set imap = CreateObject("Chilkat.Imap")

' Use TLS

' Login
success = imap.Login("myLogin","myPassword")

' Here are examples of different search criteria:

' Return all messages.
allMsgs = "ALL"

' Search for already-answered emails.
answered = "ANSWERED"

' Search for messages on a specific date.
' The date string is DD-Month-YYYY where Month is
' Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, or Dec.
onDate = "SENTON 05-Mar-2007"

' Search for messages between two dates.  SENTBEFORE
' finds emails sent before a date, and SENTSINCE finds
' email sent on or after a date.  The "AND" operation
' is implied by joining criteria, separated by spaces.
betweenDates = "SENTSINCE 01-Mar-2007 SENTBEFORE 05-Mar-2007"

' Another example of AND: find all unanswered emails
' sent after 04-Mar-2007 with "Problem" in the subject:
complexSearch1 = "UNANSWERED SENTSINCE 04-Mar-2007 Subject ""Problem"""

' Find messages with a specific string in the body:
bodySearch = "BODY ""problem solved"""

' Using OR.  The syntax is OR <criteria1> <criteria2>. 
' The "OR" comes first, followed by each criteria.
' For example, to match all emails with "Help" or "Question" in the subject.
' You'll notice that literal strings may be quoted or unquoted.
' If a literal contains SPACE characters, quote it:
orSearch = "OR SUBJECT Help SUBJECT Question"

' ----------------------------------------------
' Strings are case-insensitive when searching....
' ----------------------------------------------

' Find all emails sent from yahoo.com addresses:
fromSearch = "FROM yahoo.com"
' Find all emails sent from anyone with "John" in their name:
johnSearch = "FROM John"

' Find emails with the RECENT flag set:
recentSearch = "RECENT"

' Find emails that don't have the recent flag set:
notRecentSearch = "NOT RECENT"
' This is synonymous with "OLD":
oldSearch = "OLD"

' Find all emails marked for deletion:
markedForDeleteSearch = "DELETED"

' Find all emails having a specified header field with a value
' containing a substring:
headerSearch = "HEADER DomainKey-Signature paypal.com"

' Find any emails having a specific header field.  If the 
' 2nd argument to the "HEADER" criteria is an empty string,
' any email having the header field is returned regardless
' of the header field's content.
' Find any emails with a DomainKey-Signature field:
headerExistsSearch = "HEADER DomainKey-Signature """""

' Find NEW emails: these are emails that have the RECENT flag
' set, but not the SEEN flag:
newSearch = "NEW"

' Find emails larger than a certain number of bytes:
sizeLargerSearch = "LARGER 500000"

' Find emails marked as seen or not already seen:
seenSearch = "SEEN"
notSeenSearch = "NOT SEEN"

' Find emails having a given substring in the TO header field:
toSearch = "TO support@chilkatsoft.com"
' A more long-winded way to do the same thing:
toSearch2 = "HEADER TO support@chilkatsoft.com"

' Find emails smaller than a size in bytes:
smallerSearch = "SMALLER 30000"

' Find emails that have a substring anywhere in the header
' or body:
