Sending a mutiple of data to a string

[Ak star]

I have designed a code that sends a string to the string indicator, however if I send another string the previous string gets deleted and the new string gets display. I was wondering if I could improve my code so it can keep display a new string every time.

Your VI only executes once.  You need to put a while loop around it with a stop button to stop the VI.  Also put in some timing VI's so it doesn't run infinitely fast.

Then use a shift register to store the string data, use concatenate strings to add new data to the end of your existing data.  You will probably also want to add a carriage return or new line character as well.

I put in a while loop but i don't know how to store the string data to the shift register.

Sorry, I am still a beginner at this forum. Now i have a similar problem but this time with the numeric indicator. I want the indicator to add the new value with the previous values and so on when i press sent.

You need a shift register for that as well.  I don't know where exactly you want to do that so I'll just post a screenshot of an example.

Shift registers are a basic LV structure you need to learn.  I would recommend you learn more about LabVIEW from here. How to Learn LV

PS  In your code, the spelling should be "origin" not "orgin".

For the x and y, you just another another shift register for each of them like you have for the string. Instead of concantanating the string, you would use the add function.

p.s. You don't need those local variables at all. Place the indicators outside the case statement.

Hi Dennis,

I used two shift register for x and y, also I include the add function. However, it doesn't work and the reason is the shift register value is always Zero. This is why it doesn't add the new values with the previous values because it adds the new value with Zero.
