How to save the details entered?

[Neha987]

I am attaching a vi. I need to read the information from the text file then I need to enter it into the block but i am not able to understand how to remove the concatenated string into the parts required for the block.

See attached VI. But I suggest you use config files instead as they are more flexible and standardized. They are in the file palette.

An error is occuring when I am trying to run this vi. I am attaching the screenshot of the error.

Hi Neha,

so there is an error with your VI - and all we get is an image of the error message.

What kind of help do you expect?

EOF of your datafile is encountered. Either the file or your constants/settings in your VI are wrong…

The error is due to not having and End Of Line character at the end of the last line.  Or you could just ignore the error (Clear Error.vi, set error code to ignore to 4).

Oh, I didn't bother to check that. Just add a return last in the file to get rid of the error.

If you right click on your Read from File function and choose Read Lines, then wire a -1 to the "Count" input, you'll get an array of strings. That should be easier to parse as needed (for example using String to Path).

I am attaching a VI. It creates a notepad and then reads the details from the notepad and enters in the input. I need something like an update button so that when it is clicked then a popup comes and then we enter the new details (in the same input format) which then updates this detail in the notepad and is entered in the input.

The VI reads from a text file and writes to a text file…

So you want to handle some GUI events?

You need a button on your frontpanel.

In the block diagram you need a loop with an event structure to handle events.

In the "button: value change" event you can call your "popup" VI, which ask for user input and again waits for user action (like a "Finished" button) on its own.

In your main VI you are getting the user input from your popup VI and save it to your text file.

Basic LabVIEW stuff: did you take the Training resources as has been suggested several times before?

Thank you..........It's not basic for a beginner like me!
