Problem regarding Table Control

[Sarang Jaiswal]

Hey all,

My name is Sarang Jaiswal. I have just started working with LabVIEW . I have some basic doubts. The following example is no where related to any Real Time Application.

I am now learning Clusters so I have created two clusters, one is populated with "Meter control" and an "OK Button" and other is populated with Table control, "Numeric control" and "String Control".

Now when I move the Needle of the Meter the value in the Numeric control and the String control changes. Also when I press the Record Button the values in the Numeric control and String control is copied to the table.

The problem is when ever I click the Record button the values are over written and the previous value is lost . I want that when ever I press Record Button the new values are inserted in the new row of the Table.

I am attaching the VI with this . Please see this vi.

Also as I am new to LabVIEW please suggest some Improvement in my program so that I can do some efficient programming.

Thank You,

Hi Sarang

I can't open your vi, but according to your description, you do not fill the table correctly.

The table-control is a 2D-array of strings.

Just have a look at the simple vi I attached. You can set 5 different value and append them to the table.

Hope this helps.

You need to built your table in a shift register so the new data is appended to the old data. See attached quick modification for some ideas.

(Also don;t forget to add a delay or an event structure to your while loop. Your VI runs a maximum rate consuming all CPU. My example uses an event structure so the loop only executed when needed.
