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

* See Get Yahoo Mail OAuth2 Access Token for Desktop App 
* for sample code showing how to obtain a Yahoo Mail access token.

* In this example, our access token was previously saved to the following file which contains JSON like this:
* {
*   "access_token": "kCVQdnOdul...LHucA--",
*   "refresh_token": "AIenVXETSo0jklFBVkPS8vVm8E.Ej9ToRG.xDbDYmZ65WIs5t6CZhDrD",
*   "expires_in": 3600,
*   "token_type": "bearer",
*   "xoauth_yahoo_guid": "HGDQCVF5JB4YDOWHITQJFBHCWA"
* }

loJson = CreateObject('Chilkat.JsonObject')
lnSuccess = loJson.LoadFile("qa_data/tokens/yahooMail.json")
IF (lnSuccess <> 1) THEN
    ? "Failed to load Yahoo Mail access token file."
    RELEASE loJson
    CANCEL
ENDIF

lcAccessToken = loJson.StringOf("access_token")

* Do OAuth2 authentication by using the access token as the password in the Login method below...
loImap = CreateObject('Chilkat.Imap')

loImap.Ssl = 1
loImap.Port = 993

* Connect to the Yahoo IMAP server.
lnSuccess = loImap.Connect("imap.mail.yahoo.com")
IF (lnSuccess = 0) THEN
    ? loImap.LastErrorText
    RELEASE loJson
    RELEASE loImap
    CANCEL
ENDIF

* Indicate that XOAUTH2 authentication is to be used:
loImap.AuthMethod = "XOAUTH2"

* Login
* Use the email address of the Yahoo Mail account that granted authorization.
lnSuccess = loImap.Login("user@yahoo.com",lcAccessToken)
IF (lnSuccess <> 1) THEN
    ? loImap.LastErrorText
ELSE
    ? "Successfully authenticated with Yahoo IMAP using XOAUTH2!"
ENDIF

* Get the list of mailboxes.
lcRefName = ""
lcWildcardedMailbox = "*"
lnSubscribed = 0

loMboxes = CreateObject('Chilkat.Mailboxes')
lnSuccess = loImap.MbxList(lnSubscribed,lcRefName,lcWildcardedMailbox,loMboxes)
IF (lnSuccess = 0) THEN
    ? loImap.LastErrorText
    RELEASE loJson
    RELEASE loImap
    RELEASE loMboxes
    CANCEL
ENDIF

i = 0
DO WHILE i < loMboxes.Count
    ? loMboxes.GetName(i)
    i = i + 1
ENDDO

* Sample output looks like this:

* Archive
* Bulk Mail
* Draft
* Inbox
* Inbox/emailsWithAttach
* Inbox/test
* Sent
* Trash

* Disconnect from the IMAP server.
lnSuccess = loImap.Disconnect()
