how can I change values in an array interactively

[ottomueller]

I've loaded a data profile as an array of numbers.
Some of the array values I want to change interactively and work with the thus modified array.
I don't know how to transfer the data from the Input-Indicator to an Output-Control.


Thanks for every hint.

Inputs are controls and outputs are indicators. Could you clarify what you mean by "Input-Indicator" or "Output-Control"???

In general, you transfer data from a control to an indicator using a wire between them ;).

Maybe I don't understand the question. Could you attach a simple example of your program?

thanks for answering.
Transfering data from an control to an indicator is really a simple job.

But the other way round, I don't now how to manage:
I've imported data from a text file into an array. Some of the numbers of the array I want to modify and use the modified array for further tasks in the application.
Therefore the key question is: how to initialize an array with values depending from the application?

Hope it's now more clear what the problem is.

If you need to modify the data in a control programmatically, you can write to a local variable of the control or write to a value property of the control.

To modify an existing array, you don't need any of this. Take your array and feed it into a shift register of a loop. Inside the loop you replace the desired array elements until you are satisfied. After the loop ends, the modified array exits the shift register on the right for further processing.

Here's a simple example how to modify an existing array as mentioned above. (LabVIEW 7.0)
