Xojo Plugin Requires Chilkat v11.0.0+

Delete All IMAP Email

Demonstrates two ways to delete all email in a mailbox on an IMAP server. Xojo Plugin

Dim success As Boolean
success = False

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

Dim imap As New Chilkat.Imap

//  Turn on session logging:
imap.KeepSessionLog = True

//  Connect to an IMAP server.
//  Use TLS
imap.Ssl = True
imap.Port = 993
success = imap.Connect("imap.example.com")
If (success = False) Then
    System.DebugLog(imap.LastErrorText)
    Return
End If

//  Login
success = imap.Login("myLogin","myPassword")
If (success = False) Then
    System.DebugLog(imap.LastErrorText)
    Return
End If

//  Select an IMAP mailbox
success = imap.SelectMailbox("Inbox.RubyMail")
If (success = False) Then
    System.DebugLog(imap.LastErrorText)
    Return
End If

//  Get the complete set of Uids for email in the selected mailbox.
Dim messageSet As New Chilkat.MessageSet
success = imap.QueryMbx("ALL",True,messageSet)
If (success = False) Then
    System.DebugLog(imap.LastErrorText)
    Return
End If

//  Set the Deleted flag for each message.
//  (ExpungeAndClose must be called to finalize the delete.)
success = imap.SetFlags(messageSet,"Deleted",1)
If (success = False) Then
    System.DebugLog(imap.LastErrorText)
    Return
End If

//  Alternatively, the Deleted flag may be set for each UID
//  individiually, but this is less efficient:
Dim i As Int32
i = 0
Dim n As Int32
n = messageSet.Count
While i < n
    success = imap.SetFlag(messageSet.GetId(i),messageSet.HasUids,"Deleted",1)
    If (success = False) Then
        System.DebugLog(imap.LastErrorText)
        Return
    End If

    i = i + 1
Wend

//  Expunge and close the mailbox.
success = imap.ExpungeAndClose()
If (success = False) Then
    System.DebugLog(imap.LastErrorText)
    Return
End If

//  Display the session log.
System.DebugLog(imap.SessionLog)

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