How to customize TestStand Login & Logout Procedure to read list of available users from ini file

I want to change TestStand Login & Logout Procedure:

1. When TestStand is opened, TestStand must read list of users that are defined in the sistem file: can be ini file, txt file, excel file. The drop down menu in the Login popup menu must be populated with that users.

2. User then select his name from the drop down menu in the TestStand Login popup menu.

3. List of users should also tell TestStand if the user that wants to login is educated correctly so that he can login to teststand. If this is true, user can login to teststand, otherwise TS tells user that they don't have competences to use TS.

I used this link to customize TestStand Login & Logout Procedure:

I have copied FrontEndCallback.seq and Code Modules to TestStand Public-Components-Callbacks-Frontend folder.

Now I need help with moderating LoginUser.vi to realize the project.

Thank You for Your help
