username and password authentication

[மணிகண்டன்]

Use either .csv or .ini file to store the usernames and passwords.

you can easily read these files. 

If you want to make your authentication very highly secured. Then, you have to go for some other file format which is not readable by humans.

That is probably the single worst suggestion that could be made on storing passwords and user names.  Please don't do this, unless it is a homework assignment.  Any real project needs to avoid storing passwords in plain text.

I think your problem is not the function itself. I think it's LabVIEW knowledge.

According to your information in your VI, try to use search 1D array. it might direct you to something.

I may also suggest you to find some training or book on LabVIEW beginner. so you will know where to start.

As Suggested you should take some tutorials.

To Suggest for your Requirement you should use 2D Array (1 Column for UserName and Another For Password)/ Array Cluster (Cluster of Two Elements) for Storing User Details.

In case of reading from the file, format the Read Value in above suggested format.

Then User Search 1D Array to Find The User Name, If Search 1D Array Gives Any Value other than -1, use the Index to get the Password From the Password Column.

Then Compare the Password entered by the user and the Passed you extracted based on User Name from 2D Array.

Same Applies for Cluster data as well.
