Programmically Call Run-As Dialog

Does anyone know if it is possible to call the Run-As dialog, and return a Token
handle that can be used by ImpersonateLoggedOnUser? I would like to be able to
allow my program to change users while running, without forcing a restart of the
program. LogonUser and CreateProcessWithLogonW do not do what I'm looking for,
as they require the users password. I do not want to ask the user to enter their
password into my program.

Your best bet is to use CredUIPromptForCredentials. Look up the Credentials
API in MSDN, it's too messy to describe here.
