Combo box to code

[treadagon]

The column index input is disabled and if I create a constant on it some wires break. Although I put a constant 0 to rows index (I admit I forgot it) but it still disappear the values I'm inserting in the combo box. (did you see the vi I attached previously?)

Hi treadagon,

I hope you're not too mad at me with my several questions... (If you are I sincerely  apologize) I have one more question: when I try to connect the output of the last index array to a visa write (instead of a subarray indicator) I get a broken wire. How I send the element to a visa write block?

Hi treadagon,

if you use 2d array and you want a single element you has to index row and column. The picture shows how you can work with two 1d arrays.

In the event structure at the flag on the left there are 3 options: "source", "type" and "time" how do I choose "NewVal"?

What is the constant zero "0" on your image?

Hi treadagon,
you can resize this box and if you click on it you can change the selection.

When I resize and click on it it shows me only these 3 choices to change the flag.

Hi treadagon,
the values you can select there depend on which event you select in the event structure. What you describe sounds like the "Timeout" Event. Change for example to a value change event to get the value selection.

I have a device that measures the blood pressures. I've writed the following vi. When the device finishes the measurement it sends a string "\02999\03" when I recieve it I send the command to request the measurements from the device. 2 questions?

1)Is my vi correct?
2)I want the measurements stay on the screen till I press a boolean. How can I do that?

Hi treadagon,

you shouldn´t close the VISA resource if you want to use it later. I recommand to use a state mashine architecture.
