Extend Standard Microsoft Sample Vista Credential Provider(repost)

I need to extend the Microsoft Credential Provider Sample: "SampleHardwareEventCredentialProvider" with the change password funtionality. I want to trap the standard CTRL-ALT-CANC and then "Change Password" and the "Control Panel\User Accounts" way. What I need is a pop-up with a custom form asking for a code(this value could be hardcoded) before permitting to change password. If this code is correct the form should ask just for the new password (with reconfirm field) and then change the password. Don't worry if you need old password to make a success change, this value could be hardcoded too. All should be well commented and clear. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
