How do I get a ticket via API for use with OCX?

[#1]

I am writing a Win Form app that uses the OCX.

I want to pass a qvp address as part of the OpenDocument API to the OCX that includes a ticket so that QVServer does not try to popup a password dialog, e.g.

OpenDocument("qvp://host/file?ticket= .....")

or

OpenDocument("qvp://user@host/file?ticket= .....")

How do I get a ticket using an API?

I am NOT writing a web app that uses JavaScript to do something like:

http://webhost/qvajaxzfc/qvsviewclient.aspx?cmd=<Global%20method='GetTicketForMe'%20/>
