Hi Iskander
I downloaded the code but I do not understand your application or what are you trying to do, it will be better as Ranjeet_Singh said “State what problem you are facing i.e. what is expected and what is actual in you VI which you are going to upload”
In the VI I notice that the login VI is not wired to anything and the while loop will be executed at the same time in other words the login window is not doing anything.
