Modifying a read from text file

[stwlee]

I understand that in order to read from a text file and display the resulting array in a control, you need to use the property nodes. I've set up the VI to do exactly that.

Now, however, I want to be able to modify the resulting control so that the indicator changes as well. As far as I can tell, the attached VI does this with some small complications. Because of the way the case structure is set up, the timing of the change to the control must be exactly right so that the value will be caught on the right side of the loop (I've put the VI in "Run Continuously" mode).

Is there a better way I can accomplish a similar task and will transition the changes easier?

I've attached the VI as well as a sample text file filled with arbitrary numbers.

Who says you have to use a property node?  Use a local variable.  It is a lot more efficient and does the same job.

Now for your indicator...USE DATA FLOW.  Wire directly to your indicator from where you are updating your control.

Other edits:  Only write to the control inside of the case structure.  This will make things simpler.

The False case is empty.

Thanks a bunch. I changed it a little, because I wanted the display to show the real time changes as opposed to what was being written so I left that connected outside.
