VI of the Day (8/25/2009)

[Darin.K]

Today a simple object which unleashes tremendous power, "Property Node"

I have enclosed the somewhat whimsical VI that I threw together this morning which uses the FP:Transparency property.  Just move the mouse in and out of the FP window, and adjust the scale.  Even if you've used these hundreds of times I'll bet there is a property that you haven't experimented with.  I'd like to see some cool examples of "Stupid VI tricks", things you can do using properties when you no longer worry about why you would want to.

That is a fun property. I can think of a few places that I can use this property.

An elegant way to start a VI is to "fade in"...

As there are so many properties, this could get an enormous thread with little structure. Maybe you broaden the scope of your 'VI of the day' to properties as well and post an occasional 'property of the day'. Ben did serve us ObjHighlighting as a mini-nugget in the past. This way you won't run out on '... of the day' the next centuries. And also, there are hidden properties only visible to those that wander alone in the darkness...

Very cool, but unfotunately it doesn't meet the requirement of "stupid."  It's actually quite clever and useful.  😉

In my Nugget;

“Adaptive Save Restore”

"A Case Study of Exploiting Control References to Reduce Development Time"

I used this code construct

 

Without it the code would not work. If nothing else is is a good example of what happens when the wife goes away for the week-end and leaves me home alone with LV.

I didn't like that the mouse down event activated when you clicked on the label of a control.  So I made free labels with the text I wanted.  In this application I regularly greyed out items depending on selections. 

For example, in the following UI if you click on a drop down box, the control becomes enabled, and the label turns black.  However, if you first click the label nothing happens.

So I wrote code to hide the labels with the controls.

  

The text is the Label value for the control for the corresponding free label. 

This is about the most useless thing I remember doing with properties.  I was real bored at work that day.

... and for those of you that are stuck in LV 7.1 or earlier...

In this thread we explore what happens when you start clicking on part of a graph and doing a "create reference".

 That functionality was shut-off in LV 8 and above but it did let you get at cursor properties that were otherwise not exposed.
