LabVIEW
Re-initializing my array with reset button
Solved!
Please attach a VI. Since we can't see any part of your code (even a picture of the Block Diagram) it's very unlikely we will specify the problem accurately enough to help you.
Dear Jarrold,
Thank you for uploading the VI. Unfortunately, my monitor is not large enough to work out how your VI works. My first suggestion would be that a large amount of space seems to be taken up by case structures containing a large number of property nodes, setting the same property for each node - for example "Visible".
You can greatly improve readability by instead creating a cluster containing all of the references to controls in your application, then creating a subVI containing for example "Cluster to Array" then an autoindexed For loop, then the Property Node inside the loop with a constant value.
If you always want to operate on all of the values, and don't need to ever control specific references, then you can alternatively just build an array of references and forget about using a cluster - this is simpler, but problematic when you decide you want to change only one value, for example. Therefore, I would suggest a cluster (possibly including arrays of references rather than individual references, if you have a set of the same type of references and know that the index is sufficient to pick out the reference you need).
As a concrete example, in the Logging Volt case, under a True case, there is a case structure wired to what looks like a custom control Enum, or possibly radio button control, in which each case makes one control visible and hides 8 other controls. With an array of those 9 references, you could create a subVI which first uses 'Delete from Array' node to split based on the index, using the "Control Panel" value (make sure you have the references in the same order as the enum values!) and then a For loop to make 8 controls invisible, and a separate property node to make one property visible. An example is given below. The attached VI is backsaved to 2012.
There are some fairly strange constructs in there. My favorite so far is the darnedest reverse columns Iv'e ever seen
Which is slightly flawed in implementation. had we shifted the decremented size we could avoid swapping the center column with itself!
Hi RTSLVU
Sorry for giving you such a headache because I am pretty new to Labview. I am trying to work on it and improve on my codes! 
Hi Jarrold,

I would suggest that the greatest single step you can take to aid understanding of your code (not just for forum users, but far more importantly for yourself, or people you work with/for) is to use (more?) subVIs.
These are just 32x32 pixels on a block diagram, and when they have a suitable icon set, can reduce vast swathes of the diagram to a small, easily understood block. They additionally prevent the need to copy and paste code into multiple places, which rapidly becomes a maintenance nightmare when you need to change something in that code.
I'm not sure if you're already using a project file, but if not you should also use one of those. They are used to collect groups of VIs so that they form one entity (but don't upload a .viproj file to the forums - they don't contain code). Instead zipped directories can be uploaded if the problem is larger than one VI.
