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()


destroy loo_Imap
destroy loo_MessageSet
