writing to a table in labview

[akath]

Hello everyone,

Iam new to  labview and have to make an application where when the user presses a  button   the  data  in 3  numeric controls get  stored  in  a table.

and when user  presses the  button  again new values get stored in the next row.

I am not able to figure out how to do it.

Any help will be greatly appreciated. Thanks for your help in advance.

Hi Raj,

you can use the "Write to Spreadsheet file" function with true connected to "append to file".

You can use the "Event Structure" (to wait for the user input, button pressed) in a while loop so it waits repeatly for the command. Inside them you can use what MikeS81 said, for writting the necessary data in the wanted table.

For the program to wait for the button-input, rigth click the "Event Strucutre"'s border and select "Add Event Case..." option. Then just select your button and chose "Value change" at the Event box.

Hi Mike

I wan't to write the data to  a table on my front panel not  a file. How do I use the function given by you  to write in a table.

Hi Raj,

you can use a 2d array which you store in a shift register. Use the "add array" function for a new line.

Hi Mike,

Thanks for your reply. But I was not able  to  solve my problem from the image you give me. So  could you  please  send me its VI.

I  was  not able to make a shift register for event case which monitors when  the button for  updating table  is pressed. 

Thanks in advance

akath,

the shift register has to be at the while loop window, not at the event case...

Hope the following VI can help you
