// 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
Dim success As Boolean
success = imap.Connect("imap.someMailServer.com")
If (success <> True) Then
    System.DebugLog(imap.LastErrorText)
    Return
End If

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

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

Dim messageSet As Chilkat.MessageSet

// Get the complete set of Uids for email in the selected mailbox.
messageSet = imap.GetAllUids()
If (imap.LastMethodSuccess <> True) 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 <> True) 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
Dim n As Int32
n = messageSet.Count
For i = 0 To n - 1
    success = imap.SetFlag(messageSet.GetId(i),messageSet.HasUids,"Deleted",1)
    If (success <> True) Then
        System.DebugLog(imap.LastErrorText)
        Return
    End If

Next

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

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

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