While working on version 1.0.6 of BN+ Converter Pro, which is scheduled to be released this weekend, I created a dialogue that allows users to edit their password. It features live validation, user friendly feedback, and optional authentication.
The dialog is written in VB.Net, and can be downloaded on BN+ Discussions. Dutch support can be found here.
This dialog will be included in the 2.0.3 release of BN+ Framework, which is scheduled to be released on the 23rd of May. This release will feature some high quality new classes and dialogs and a few bug fixes.
