Delete All IMAP Email

Demonstrates two ways to delete all email in a mailbox on an IMAP server. C++

#include <CkImap.h>
#include <CkMessageSet.h>

void ChilkatSample(void)
    {
    bool success = false;

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

    CkImap imap;

    //  Turn on session logging:
    imap.put_KeepSessionLog(true);

    //  Connect to an IMAP server.
    //  Use TLS
    imap.put_Ssl(true);
    imap.put_Port(993);
    success = imap.Connect("imap.example.com");
    if (success == false) {
        std::cout << imap.lastErrorText() << "\r\n";
        return;
    }

    //  Login
    success = imap.Login("myLogin","myPassword");
    if (success == false) {
        std::cout << imap.lastErrorText() << "\r\n";
        return;
    }

    //  Select an IMAP mailbox
    success = imap.SelectMailbox("Inbox.RubyMail");
    if (success == false) {
        std::cout << imap.lastErrorText() << "\r\n";
        return;
    }

    //  Get the complete set of Uids for email in the selected mailbox.
    CkMessageSet messageSet;
    success = imap.QueryMbx("ALL",true,messageSet);
    if (success == false) {
        std::cout << imap.lastErrorText() << "\r\n";
        return;
    }

    //  Set the Deleted flag for each message.
    //  (ExpungeAndClose must be called to finalize the delete.)
    success = imap.SetFlags(messageSet,"Deleted",1);
    if (success == false) {
        std::cout << imap.lastErrorText() << "\r\n";
        return;
    }

    //  Alternatively, the Deleted flag may be set for each UID
    //  individiually, but this is less efficient:
    int i = 0;
    int n = messageSet.get_Count();
    while (i < n) {
        success = imap.SetFlag(messageSet.GetId(i),messageSet.get_HasUids(),"Deleted",1);
        if (success == false) {
            std::cout << imap.lastErrorText() << "\r\n";
            return;
        }

        i = i + 1;
    }

    //  Expunge and close the mailbox.
    success = imap.ExpungeAndClose();
    if (success == false) {
        std::cout << imap.lastErrorText() << "\r\n";
        return;
    }

    //  Display the session log.
    std::cout << imap.sessionLog() << "\r\n";

    //  Disconnect from the IMAP server.
    success = imap.Disconnect();
    }
