(Classic ASP) 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.

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Imap")
set imap = Server.CreateObject("Chilkat.Imap")

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

' Connect to an IMAP server.
' Use TLS
imap.Ssl = 1
imap.Port = 993
success = imap.Connect("MY-IMAP-DOMAIN")
If (success <> 1) Then
    Response.Write "<pre>" & Server.HTMLEncode( imap.LastErrorText) & "</pre>"
    Response.End
End If

' Login
success = imap.Login("MY-IMAP-LOGIN","MY-IMAP-PASSWORD")
If (success <> 1) Then
    Response.Write "<pre>" & Server.HTMLEncode( imap.LastErrorText) & "</pre>"
    Response.End
End If

' Select an IMAP mailbox
success = imap.SelectMailbox("INBOX")
If (success <> 1) Then
    Response.Write "<pre>" & Server.HTMLEncode( imap.LastErrorText) & "</pre>"
    Response.End
End If

' The LastResponse property contains the full response of the last command.
selectResponse = imap.LastResponse
Response.Write "<pre>" & Server.HTMLEncode( selectResponse) & "</pre>"

' 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.

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.StringBuilder")
set sbResponse = Server.CreateObject("Chilkat.StringBuilder")
success = sbResponse.Append(selectResponse)

' Get just the list of flags:
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.StringBuilder")
set sbFlagList = Server.CreateObject("Chilkat.StringBuilder")
success = sbFlagList.Append(sbResponse.GetAfterBetween("* FLAGS","(",")"))
Response.Write "<pre>" & Server.HTMLEncode( sbFlagList.GetAsString()) & "</pre>"

' sbFlagList contains this:  
' 
'     \Answered \Flagged \Draft \Deleted \Seen $Forwarded $NotPhishing $Phishing $label1 $label2 $label3 $label4 $label5 Junk NonJunk
' 

' Make sure no more than one SPACE char in a row exists.
success = sbFlagList.TrimInsideSpaces()
' Modify sbFlagList to one flag per line
numReplaced = sbFlagList.Replace(" ",vbCrLf)

' Load a StringTable with the flag names.
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.StringTable")
set flagsTable = Server.CreateObject("Chilkat.StringTable")
success = flagsTable.AppendFromSb(sbFlagList)

' Iterate over the individual flag names:
i = 0
Do While i < flagsTable.Count
    Response.Write "<pre>" & Server.HTMLEncode( i & ": " & flagsTable.StringAt(i)) & "</pre>"
    i = i + 1
Loop

' The output is:
' 
' 	0: \Answered
' 	1: \Flagged
' 	2: \Draft
' 	3: \Deleted
' 	4: \Seen
' 	5: $Forwarded
