checkbox value fix in array of cluster

[ssnp]

Hi!

   I am trying to modify a vi which contain checkboxs in cluster and bunch of cluster contain in arrays. I want to fix the value of checkbox as true or false for different set of cluster in the arrays. Is there any way to do it?

Hi ssnp,

I have no idea why you want to use an Unbundle with an array. Unbundle will only work with clusters...

To set some default values you create your array of clusters with your preferred settings and then right-click the array (!) and select "data operations"->"set current as default". Or you create a constant of your array and use that one...

What do you mean by "fix". What's wrong with the controls?

If you are trying to change the value of a specific checkbox in a specific element then you need to perform a Replace Array Element, since you have an array of clusters. You'd use Index Array to extract the specific one you want to change, then Bundle By Name to select the specific element in that cluster, set its value, and then feed the resulting cluster into the Replace Array Element function. Something like this (changes the A4 checkbox for the 15th element in the array):

Or use the Inplace Element Structure

You have not explained what you mean by "fix", but if you don't want the operator be able to change them, configure them as disabled (right-click..advanced..enabled state..disabled"). Now they will act more like indicators: You can still programmatically modify them, but the user is prevented from changing them manually.

Otherwise, please be more specific with your terminology. For example the word "fix" has a very different meaning to a dog. 😉

Thanks for reply

    The cluster contain parameters for different sub vi. I will correct my question further. When i set the check box as true and close the vi. it is going back to default value. When i set true as default value, all the checkbox in  all the cluster in the array is set to true. I want selectively true and false.

This is by design. When you change the value of a control it will not (and should not) change the default value for the control. You have to explicitly specify that the current value of the control should be used as the default value for when the VI is opened, or if the VI is used as a subVI, and the terminal is left unwired (if the control is tied to the connector pane).

This is not clear. Are you setting it by clicking on it on the front panel, or programmatically? If you're setting it by clicking on it, then there is no way all of the other elements would be "automagically" updated to the same value. If you are setting it programmatically, then you have an error in your code.

I want selectively true and false.

You are still using vague terms and not clearly explaining what you are trying to do. Is your VI supposed to show what you are trying to do? I don't understand what the VI is supposed to do. I can see what it does, but its purpose escapes me.

Your array has ~138 elements. Each element is a cluster. Different array elements currently have different values for the booleans, for example #68 is all FALSE while #69 is TRUE for A1 and B1.

This is in direct contradiction to your statement!

After setting all array elements to the desired pattern, Make sure you set the current value of the array (not the cluster element!) to the default and save the VI.

(If you change the default for the actual cluster, it will apply to new elements that you add by clicking on an (greyed) element past the current array array size).

The cluster contain parameter for another sub vi . Indies to array will select the cluster ie the parament then it is passed to sub vi. I was trying to achive it not not able .Making the array element

default solved the problem.  Thanks!
