Windows Login Dialogue in LabVIEW

[shane5ab]

Hi Erveryone,

I want to show the Windows Login Dialogue from LabVIEW application for Windows level authentication and check if the user is member of a specific group.

I have developed a code which validates the credentials and then if the credentials are valid checks for the user to be in a specific group.

As far as the functionality is concerned, I have achieved what I am after, but we want to implement a Biometric Scanner for Authentication purposes.

The Biometric application can detect the Windows Login Dialogue box and TestStand Login Dialogue box, I hope they are a specific kind that is why recognised by biometric application.

I tried to call the TestStand Login Dialogue for the same purpose, but as it only works with the TestStand users, and keeps on popping up again and again if some other user name is used.

I searched on google for Windows function implementation and came across the following links:

I was unable to implement this in LabVIEW, could some one please help me in implementing this in LabVIEW.

Kind Regards

Hi shane5ab,

From the second link you provided, it looks like a DLL is provided (either that or C# code which can be compiled). You can use this DLL with LabVIEW by using Call Library Function Nodes. This tutorial may be helpful: https://decibel.ni.com/content/docs/DOC-1690 .
