PowerBuilder Requires Chilkat v11.0.0+

Delete All IMAP Email

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

integer li_rc
integer li_Success
oleobject loo_Imap
oleobject loo_MessageSet
integer i
integer n

li_Success = 0

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

loo_Imap = create oleobject
li_rc = loo_Imap.ConnectToNewObject("Chilkat.Imap")
if li_rc < 0 then
    destroy loo_Imap
    MessageBox("Error","Connecting to COM object failed")
    return
end if

//  Turn on session logging:
loo_Imap.KeepSessionLog = 1

//  Connect to an IMAP server.
//  Use TLS
loo_Imap.Ssl = 1
loo_Imap.Port = 993
li_Success = loo_Imap.Connect("imap.example.com")
if li_Success = 0 then
    Write-Debug loo_Imap.LastErrorText
    destroy loo_Imap
    return
end if

//  Login
li_Success = loo_Imap.Login("myLogin","myPassword")
if li_Success = 0 then
    Write-Debug loo_Imap.LastErrorText
    destroy loo_Imap
    return
end if

//  Select an IMAP mailbox
li_Success = loo_Imap.SelectMailbox("Inbox.RubyMail")
if li_Success = 0 then
    Write-Debug loo_Imap.LastErrorText
    destroy loo_Imap
    return
end if

//  Get the complete set of Uids for email in the selected mailbox.
loo_MessageSet = create oleobject
li_rc = loo_MessageSet.ConnectToNewObject("Chilkat.MessageSet")

li_Success = loo_Imap.QueryMbx("ALL",1,loo_MessageSet)
if li_Success = 0 then
    Write-Debug loo_Imap.LastErrorText
    destroy loo_Imap
    destroy loo_MessageSet
    return
end if

//  Set the Deleted flag for each message.
//  (ExpungeAndClose must be called to finalize the delete.)
li_Success = loo_Imap.SetFlags(loo_MessageSet,"Deleted",1)
if li_Success = 0 then
    Write-Debug loo_Imap.LastErrorText
    destroy loo_Imap
    destroy loo_MessageSet
    return
end if

//  Alternatively, the Deleted flag may be set for each UID
//  individiually, but this is less efficient:
i = 0
n = loo_MessageSet.Count
do while i < n
    li_Success = loo_Imap.SetFlag(loo_MessageSet.GetId(i),loo_MessageSet.HasUids,"Deleted",1)
    if li_Success = 0 then
        Write-Debug loo_Imap.LastErrorText
        destroy loo_Imap
        destroy loo_MessageSet
        return
    end if

    i = i + 1
loop

//  Expunge and close the mailbox.
li_Success = loo_Imap.ExpungeAndClose()
if li_Success = 0 then
    Write-Debug loo_Imap.LastErrorText
    destroy loo_Imap
    destroy loo_MessageSet
    return
end if

//  Display the session log.
Write-Debug loo_Imap.SessionLog

//  Disconnect from the IMAP server.
li_Success = loo_Imap.Disconnect()
