Delete All IMAP Email

Demonstrates two ways to delete all email in a mailbox on an IMAP server. Visual Basic 6.0

Dim success As Long
success = 0

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

Dim imap As New ChilkatImap

' Turn on session logging:
imap.KeepSessionLog = 1

' Connect to an IMAP server.
' Use TLS
imap.Ssl = 1
imap.Port = 993
success = imap.Connect("imap.example.com")
If (success = 0) Then
    Debug.Print imap.LastErrorText
    Exit Sub
End If

' Login
success = imap.Login("myLogin","myPassword")
If (success = 0) Then
    Debug.Print imap.LastErrorText
    Exit Sub
End If

' Select an IMAP mailbox
success = imap.SelectMailbox("Inbox.RubyMail")
If (success = 0) Then
    Debug.Print imap.LastErrorText
    Exit Sub
End If

' Get the complete set of Uids for email in the selected mailbox.
Dim messageSet As New MessageSet
success = imap.QueryMbx("ALL",1,messageSet)
If (success = 0) Then
    Debug.Print 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 = 0) Then
    Debug.Print 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 Long
i = 0
Dim n As Long
n = messageSet.Count
Do While i < n
    success = imap.SetFlag(messageSet.GetId(i),messageSet.HasUids,"Deleted",1)
    If (success = 0) Then
        Debug.Print imap.LastErrorText
        Exit Sub
    End If

    i = i + 1
Loop

' Expunge and close the mailbox.
success = imap.ExpungeAndClose()
If (success = 0) Then
    Debug.Print imap.LastErrorText
    Exit Sub
End If

' Display the session log.
Debug.Print imap.SessionLog

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