Demonstrates how to read all of the email from a POP3 inbox by fetching each email by it's message number. PowerBuilder

integer li_rc
integer li_Success
oleobject loo_Mailman
integer li_NumMessages
integer i

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

loo_Mailman = create oleobject
li_rc = loo_Mailman.ConnectToNewObject("Chilkat.MailMan")
if li_rc < 0 then
    destroy loo_Mailman
    MessageBox("Error","Connecting to COM object failed")

// Set the POP3 server's hostname
loo_Mailman.MailHost = "pop.example.com"

// Set the POP3 login/password.
loo_Mailman.PopUsername = "myLogin"
loo_Mailman.PopPassword = "myPassword"

// Get the number of messages in the mailbox.
li_NumMessages = loo_Mailman.GetMailboxCount()

// Message numbers are specific to a POP3 session. 
// If a maildrop (i.e. inbox)  contains 10 messages, 
// the message numbers will be 1, 2, 3, ... 10. 
// If message number 1 is deleted and a new POP3 session 
// is established, there will be 9 messages numbered 1, 2, 3, ... 9.
