LabVIEW Idea Exchange

How many times have you created a sequence structure with two milisecond timers around a section of code to see how fast it operates.  Now the VI Profiler works great if you are only looking at whole VIs, but there are lot of cases where that the VI level is not granular enough.  A great feature would be a Benchmarking Probe.  It would work similar to a Breakpoint. It would have a Benchmark Probe Manager similar to the Breakpoint Manager in which you can enable/disable/delet benchmarking probes (very useful when you need to quickly see if the benchmarking code itself is adding excessive overhead).

Unlike a breakpoint or a probe, it requires two icons a Start/Stop of where you want to take a measurement. I would imagine that there would be two ways to insert the benchmark probe, one method would be similar to how insert a Breakpoint (in fact you could simply use the breakpoint tool and just add a right click option to convert to a benchmark probe). Once you clicked on the Wire that you wanted to "Start" the benchmark, the mouse icon would change to a the "Stop" benchmark icon and you would choose the place to Stop the benchmark. Of course if those two points weren't "In Place" and "Sequential" with each other, LabVIEW wouldn't allow you to place it.

Another method could be simply highlighting the area of code you want to benchmark and then right-clicking on the hgihlighted section, you would get an additional pop-up menu item for adding a benchmark, this would automatically place the two benchmark icons.

The Benchmark manager would give options of viewing the Total Time, Average Time, number of Runs in miliseconds, microseconds,etc in addtion to being able to enable disable, delete benchmarks.

I have a Group of numeric values.Such as

1.0

0.866

 0.5

0.2

0.1

0.0

I want to create and update a drop down menu so a user can select a numeric value(Direct calculation，do not Converted form a string), a bit like a combo box.

Hope to have this controls in the labVIEW!

Is there any tool to compare Multiple VIs (more than two i.e. about twenty) at a same time.How can I compare more than two VIs at the same time. I am an Lab Engineer I have to check assignments submitted by students and I want to know how many of them are copied from each other. Labview compare VI can only compare two VI at a time while I want to check about 30 VIs at same time.

Cuando tenemos en funcionamiento en tiempo de desarrollo un VI, que no tenemos activada la barra de herramientas de debuger, no es posible parar si ejecución, esto es especialmente grave cuando hay un error de programación y estamos en un bucle sin fin, o otro caso mas grave, es cuando un vi que tenemos como modal esta abierto en el tiempo de desarrollo, pero no esta en ejecución, por que no ha sido todavía llamado por el programa, este vi se pone en primer plano, y como no tiene código funcionando no tiene posibilidad de salida, con lo que impide cualquier acción sobre cualquier otra ventana, inclusive la del proyecto.

Seria necesario que la interrupción, del ctrl+., o cualquier otra estuviera vigente siempre, para poder detener la ejecución en tiempo de ejecución.
