I won't suggest that there is one single, silver-bullet solution that will magically convert your software dung beetles into amethyst scarabs. There we go. And there may be some other VIs that execute their code regardless of an error, in which case on their block diagram, we may not see this case structure at all. Let's review first the easiest way to approach this.The most basic subVI error handling consists of a case statement enclosing all of your functional code in each module, with the input this content
We can go a step further here and just use the polymorphic nature of our case structure and not even have to unbundle this. So I’ll double-click, open up its front panel, and go to its block diagram. I’ll go to my Cluster, Class, and Variant palette and pull out Unbundle By Name. After the user acknowledges the dialog box, the VI returns control to the main VI.4continue/stop + warnings--Displays a dialog box with any warnings and buttons, which the user can use to

Let's take a look at what's in the cluster, the difference between manual and automatic error handling, and the behavior of standard LabVIEW VIs and functions when they see an incoming Wire the error information from the beginning of the VI to the end. You know exactly what executes when. On the block diagram, these clusters are wired externally to a Case structure.
