Overview

This code snippet shows how to create a password dialog with secret editors. Numeric secret editors can be defined using s NUMSECRETED resource structure in a resource file and alphanumeric secret editors are defined using a SECRETED resource structure. This code snippet implements two example dialogs with SECRETED structures. The first one is a multiline query dialog containing password and confirmation fields and the second one is a simple text query dialog with one password field.

This snippet can be self-signed.

The following libraries are required:
