Temporarily displaying a "login screen" when a VI starts

I've finished creating an app that I want to add a screen for operator login. Once the operator enters the login text I want the login screen to disappear and the main app screen to appear.

I'm not sure how to accomplish this. Your input will be appreciated.

thanks,

todd

Try using my attached example to create a popup login screen. Depending on the status or valid login, you could continue with your application or exit.

See attched code. It was created using 7.0. Run the mainapp.vi. The main part of the login.vi came from the examples shipped with version 7.0.

ATC Herman,
Thank you for sending me an example. When I try to run mainapp.vi the app is looking for "AuthenticateUser.vi". I don't seem to be able to find this VI.

Please resend the example.

thanks again,

todd
