VB.NET Requires Chilkat v11.0.0+

Delete All IMAP Email

Demonstrates two ways to delete all email in a mailbox on an IMAP server. VB.NET

Dim success As Boolean = 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
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


'  Login
success = imap.Login("myLogin","myPassword")
If (success = False) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


'  Select an IMAP mailbox
success = imap.SelectMailbox("Inbox.RubyMail")
If (success = False) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
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
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
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
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


'  Alternatively, the Deleted flag may be set for each UID
'  individiually, but this is less efficient:
Dim i As Integer = 0
Dim n As Integer = messageSet.Count
While i < n
    success = imap.SetFlag(messageSet.GetId(i),messageSet.HasUids,"Deleted",1)
    If (success = False) Then
        Debug.WriteLine(imap.LastErrorText)
        Exit Sub
    End If

    i = i + 1
End While

'  Expunge and close the mailbox.
success = imap.ExpungeAndClose()
If (success = False) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


'  Display the session log.
Debug.WriteLine(imap.SessionLog)

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