Need help in excel and led

[Kev1823]

This has already been done using Labview-only techniques. If you can afford to enter the password/username data into a table in Labview instead of an excel spreadsheet, the Labview Basic II Course Manual can help you. It's all in exercise 1.2 'Verify Information VI' on page 1.17 onwards.

....and the second part of the exercise linking to the password/username database is found in exercise 3.1 'Login VI' on page 3.9 in the same book.

If you don't already have these manuals, they are available as e-books online if you have a browse.

Thanks for the references. I tried, but still i cant link the spreadsheet to the led.

Those references are as basic as Labview gets really, it's all written in Lehmann's terms so I'd suggest you work through those 2 exercises fully for your best chance of success.

The LED will connect to the green output terminal labelled 'Access Granted' on the teal-coloured 'verify info' block in the second VI. This LED will light upon entering a valid username/password combination into the front panel text boxes.

Hope that helps.

ok, i will try. Thanks alot for the help.

No problem at all. Hopefully that should sort out your enquiry. I personally use these 2 VI's (well, an adaption of such) for password protection for VI's that I develop and they work really well. If you need to add extra entries or users, just update your database in the first VI with the data required and hey presto, couldn't be simpler really....

These 2 VI's will only take you about 30mins or so to work through, even for the novice that I was at the time.

If you've any other queries or if you get stuck, just ask.
