(PowerBuilder) IMAP Get List of Flags

When a mailbox is selected, the server response includes a list of flags:

The FLAGS response occurs as a result of a SELECT or EXAMINE command. The flag parenthesized list identifies the flags (at a minimum, the system-defined flags) that are applicable for this mailbox. Flags other than the system flags can also exist, depending on server implementation.

This example demonstrates how to capture the SELECT (or EXAMINE) response, and parse the list of flags.

// This example assumes Chilkat Imap to have been previously unlocked.
// See Unlock Imap for sample code.

// Connect to an IMAP server.
// Use TLS

if li_Success <> 1 then
    Write-Debug loo_Imap.LastErrorText

// Login
li_Success = loo_Imap.Login("MY-IMAP-LOGIN","MY-IMAP-PASSWORD")
if li_Success <> 1 then
    Write-Debug loo_Imap.LastErrorText
    destroy loo_Imap

end if

// Select an IMAP mailbox
li_Success = loo_Imap.SelectMailbox("INBOX")
if li_Success <> 1 then
    Write-Debug loo_Imap.LastErrorText
    destroy loo_Imap
    return
end if

// The LastResponse property contains the full response of the last command.
ls_SelectResponse = loo_Imap.LastResponse
Write-Debug ls_SelectResponse

// For example, on GMail, the SELECT response looks like this:

// 	* FLAGS (\Answered \Flagged \Draft \Deleted \Seen $Forwarded $NotPhishing $Phishing $label1 $label2 $label3 $label4 $label5 Junk NonJunk)
// 	* OK [PERMANENTFLAGS (\Answered \Flagged \Draft \Deleted \Seen $Forwarded $NotPhishing $Phishing $label1 $label2 $label3 $label4 $label5 Junk NonJunk \*)] Flags permitted.
// 	* OK [UIDVALIDITY 3] UIDs valid.
// 	* 46 EXISTS
// 	* 0 RECENT
// 	* OK [UIDNEXT 4147] Predicted next UID.
// 	* OK [HIGHESTMODSEQ 402971]
// 	aaac OK [READ-WRITE] INBOX selected. (Success)

// The goal of this example is to capture the list of FLAGS.
// All IMAP servers will respond with the list of flags in a SPACE separated list enclosed in parentheses.

    Write-Debug string(i) + ": " + loo_FlagsTable.StringAt(i)
    i = i + 1
