(Visual FoxPro) IMAP Find Emails by DateSee more IMAP ExamplesExplains how to find emails by date using the IMAP protocol.Note: This example requires Chilkat v11.0.0 or greater.
LOCAL lnSuccess LOCAL loImap LOCAL lcOnDate LOCAL lcBetweenDates LOCAL lnFetchUids LOCAL loMessageSet LOCAL loEmail LOCAL lnMessageCount LOCAL i lnSuccess = 0 * This example requires the Chilkat API to have been previously unlocked. * See Global Unlock Sample for sample code. loImap = CreateObject('Chilkat.Imap') * Connect to an IMAP server. loImap.Ssl = 1 loImap.Port = 993 lnSuccess = loImap.Connect("imap.example.com") IF (lnSuccess = 0) THEN ? loImap.LastErrorText RELEASE loImap CANCEL ENDIF * Login lnSuccess = loImap.Login("myLogin","myPassword") IF (lnSuccess = 0) THEN ? loImap.LastErrorText RELEASE loImap CANCEL ENDIF * Select an IMAP mailbox lnSuccess = loImap.SelectMailbox("Inbox") IF (lnSuccess = 0) THEN ? loImap.LastErrorText RELEASE loImap CANCEL ENDIF * In the IMAP (Internet Message Access Protocol) protocol, criteria strings are used to search for emails matching specific criteria on the mail server. * When searching for emails by date, you can use criteria strings to specify the date range you're interested in. * * IMAP provides several options for searching emails by date using criteria strings. Here are the commonly used ones: * * 1. BEFORE: Searches for emails sent before a specific date. * Example: BEFORE 01-Apr-2022 * * 2. ON: Searches for emails sent on a specific date. * Example: ON 01-Apr-2022 * * 3. SINCE: Searches for emails sent after a specific date. * Example: SINCE 01-Apr-2022 * * 4. SENTBEFORE: Searches for emails whose date header (sent date) is before a specific date. * Example: SENTBEFORE 01-Apr-2022 * * 5. SENTON: Searches for emails whose date header (sent date) is on a specific date. * Example: SENTON 01-Apr-2022 * * 6. SENTSINCE: Searches for emails whose date header (sent date) is after a specific date. * Example: SENTSINCE 01-Apr-2022 * * * The date format used in IMAP criteria strings is typically a specific format like "DD-Mon-YYYY" (e.g., "01-Apr-2022"), but some servers may also accept other formats * such as "YYYY-MM-DD". It's essential to check the documentation or specifications of the IMAP server you're working with to ensure compatibility with the * date format you're using. * * By combining these date criteria strings with other search criteria (such as sender, recipient, subject, etc.), * you can effectively filter and retrieve emails based on various conditions. * * 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. lcOnDate = "SENTON 15-Apr-2024" * 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. lcBetweenDates = "SENTSINCE 12-Apr-2024 SENTBEFORE 15-Apr-2024" * We can choose to fetch UIDs or sequence numbers. lnFetchUids = 1 loMessageSet = CreateObject('Chilkat.MessageSet') lnSuccess = loImap.QueryMbx(lcBetweenDates,lnFetchUids,loMessageSet) IF (lnSuccess = 0) THEN ? loImap.LastErrorText RELEASE loImap RELEASE loMessageSet CANCEL ENDIF ? loMessageSet.ToCompactString() * Download each email in the message set. loEmail = CreateObject('Chilkat.Email') lnMessageCount = loMessageSet.Count i = 0 DO WHILE i < lnMessageCount lnSuccess = loImap.FetchEmail(0,loMessageSet.GetId(i),lnFetchUids,loEmail) IF (lnSuccess = 0) THEN ? loImap.LastErrorText RELEASE loImap RELEASE loMessageSet RELEASE loEmail CANCEL ENDIF ? loEmail.Subject * ... i = i + 1 ENDDO * Disconnect from the IMAP server. lnSuccess = loImap.Disconnect() RELEASE loImap RELEASE loMessageSet RELEASE loEmail |
