how extract a value from table?

how extract a value only from table with labview 5.0?

Hello titoulaban,

a table is just a 2D array of strings. So you should use an "index array'" to get your element from the table and maybe a string conversion function to get a numerical value, if needed.

Hi
You have to now that a table is like a array of strings. So you can easily extract the value you want . I send you a little example that will help you for sure:
With my programm  i build a random array of numbers. I convert it in string array and i write it in a table.
Then you can select a value of your table .

good luck ;o)

you also can do this by clicking on the table. all you need to do is to create a property node for the table and select selection start. The output of the node has to be unbundled and connected to the index array Sub.

if you have problems, reply then i will post an example.

Hi..

mr bartb, can i see the example?

My table is displaying some series of data from 6 types of input. I am planning to extract the data and execute them at the hardware output (serial) by reading row by row of the table.

Thanks:)

(I'm using LV 8.5)

So what exactly is the problem. You don't have code there to extract the rows or do anything with serial. All you need to get a row is the Index Array function.

That's pretty basic stuff. Have you gone through any of the tutorials?

Hi T4l

I modified you VI to extract a selected row from the table. This is quite simple by done by using the index array function. Hope this helps
