PowerBuilder Requires Chilkat v11.0.0+

IMAP Download All Email One at a Time

Demonstrates how to download every email in an IMAP mailbox one at a time as a MIME string or as an email object. (The MIME contains the full contents of the email including all attachments.) PowerBuilder

integer li_rc
integer li_Success
oleobject loo_Imap
integer li_BUid
string ls_MimeStr

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

//  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

//  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")
if li_Success = 0 then
    Write-Debug loo_Imap.LastErrorText
    destroy loo_Imap
    return
end if

//  Once the mailbox is selected, the NumMessages property
//  will contain the number of messages in the mailbox.
//  You may loop from 1 to NumMessages to
//  fetch each message by sequence number.

    //  Download the email by sequence number.
    ls_MimeStr = loo_Imap.FetchSingleAsMime(i,li_BUid)

    //  ... your application may process each MIME string...
next

//  An alternative is to download each email in the form of an
//  email object, like this:
loo_Email = create oleobject
li_rc = loo_Email.ConnectToNewObject("Chilkat.Email")

for i = 1 to n

    //  Download the email by sequence number.
    li_Success = loo_Imap.FetchEmail(0,i,li_BUid,loo_Email)

    //  ... your application may process the email object...

next

//  Disconnect from the IMAP server.
