Executing Case Structure Once In While Loop Labview Stack Overflow I trying to let this dialogue box pop out only once when the elapsed time reached 3 seconds, but somehow it constantly pop ing out because it's been constantly meeting the condition in the while loop. Use a shift register to keep values for the next iteration of your loop! (this is very basic labview stuff ).
Labview While Loop Execution Condition Stack Overflow Learn about fundamental labview structures: for loops, while loops, and case structures. understand their functionality and use cases for graphical programming. For each case, use the labeling tool to enter a single value or lists and ranges of values in the selector label at the top of the case structure. the values you enter in each selector label execute a specific subdiagram based on the input value you pass to the structure. Structures are graphical representations of the loops and case statements of text based programming languages. the following topics provide information about using structures, located on the structures palette. This tutorial has explained the functionality of case structures in labview, compared them to other programming environments, and provided examples to further illustrate their practical application.

So if i understand correctly you want some piece of code inside a while loop to run only the first time the loop runs? this can be accomplished by placing the desired code inside a case structure that is fed by a comparison with the out put of the little blue “i” block in the corner. A case structure is a primitive structure that can have multiple subdiagrams (also known as "cases"), one of which is selectively executed at runtime. a selector value determines which case is executed at runtime. Now we know how to handle multiple events by combining while loop case structure. similarly, if we want to handle n events, we can add n case structures in the while loop. So get a vi that checks that continuously in your while loop, and when your condition is met, execute what you need. also put a delay in the while loop timeout if you have an event structure to make sure you don't check every few ms using your resources unnecessarily.
