disabling array value

[Mathan]

Does the attachment makes sense?

Thanks,

An array element looks disabled if it does not exist in the array. You need to wire an array with a single element into a local variable of that control.

If you want to do this without code, you can right click the element and select Data Operations>>Delete Element.

Let's assume if there are some 1000 elements in the array and if last 50 values are wrongly entered, then is there any quick way to clear (make it as zero) or delete all the 50 elements.

Use Array Subset or Delete From Array.

[Mathan]

Great....

It works well. Thanks,,,,

[Edited: Delete from Array is better than Array subset since array subset will give only the unwanted deleted portion of the array and didn't return the required cut-off array.]

Hi mathan,

this is only true if you select the elements you want to delete. But you can use the Array subset if you select the part you want, index 0, length = array size - 50.

Just curious..  How do you know which values are wrong?

I can't able to solve your curiosity.  Actually my friend asked me for a solution for that kind of problem  he faced in his programming in Visual C++. So i got curious in solving it in LabVIEW.

The example from paulmw is quite efficient. 

You can easily convert the code to handle numerics instead of strings.  However, in that example he wanted to get rid of blanks, whereas in your case it would have to be a specific value..  But you can customize any of the suggestions to meet your needs.  Actually a good way to learn is to experiment with all sugegstions.  😉
