LabVIEW users, there’s a keyboard shortcut that might help you with object movement.  By holding down Shift while dragging any object, you can resize objects proportionally in both directions. This resize shortcut allows users to keep the original height and width ratio of the object. If you want to keep an object centered and circular, hold down the Shift and Ctrl keys while dragging the object. And yes, this also includes objects on the block diagram.

Successfully completing an application with the graphical system design approach means more than simply making a functional program that meets requirements. To help you accelerate your development, NI LabVIEW skills guides assist you in identifying which proficiency level your current application requires. You can then learn more about the skill sets important for proficiency at that level and the training options for obtaining those skills consistent with your time constraints, budget, and personal learning preferences.

With NI training courses, you learn techniques to reduce development time and improve application performance and scalability. Learn from NI and industry experts in a variety of formats, including online, virtual, and classroom settings. NI training is a smart and safe investment to unlock your application development potential.

In addition to training courses, developers and engineers using NI software can benefit from getting certified. Certification helps inspire confidence in technical skills, leading to promotions, new opportunities, and higher pay. For organizations, certification is a strategic investment that pays off in increased productivity, reduced turnover, and an overall competitive advantage.

Wouldn’t it be nice to use standard keyboard shortcuts, such as Ctrl+B for bold, for text editing in LabVIEW? If you have LabVIEW 2013, you can. Just add the following token to your INI file: QuickBold=True

 

Now, whenever you’re editing text on the front panel or block diagram of a VI, Ctrl+B will bold/unbold text.

Keep in mind that this QuickBold option is only activated while editing a text field, so you can still use Ctrl+B  for removing broken wires.

Linux has long been used in embedded system design because it’s free, open-sourced, and community grown and supported. In the past, developers concluded that Linux couldn’t be an real-time operating system (RTOS), and over the course of time have developed a plethora of hybrid approaches that combine Linux with a dedicated RTOS for use in embedded applications.The possibility of achieving real-time performance with Linux became more feasible as its use in embedded system design matured, and National Instruments jumped at the opportunity!

 

Using the PREEMPT_RT patch set, an effort at improving the Linux kernel, NI developed a Linux-based RTOS available on both the NI cRIO-9068 controller and the NI myRIO device. The best part-- the new operating system is fully supported in the NI LabVIEW 2013 development environment!

For a splash screen to become GROOVY it needs to have a strange shape, exhibit the right kind of transparency, fade in, and have some nice custom progress stuff going on.

 

Interested? Here's how to do it. Code is posted here-- download SplashScreen.zip.

Tools

The LabVIEW bit

You will need to dynamically load the splash screen and then some time after the main program. For a nice fast startup, we want to load the main program in the background and then show the front panel.

 

Startup VI

 

DynLoadSplashscreen.pngFirst, dynamically load and run the splash screen.
DynLoadMainscreen.pngThen, start loading the main program.
BringUpMainscreen.pngAfter a bit of a wait, bring up the main screen.
CleanUpSplashscreen.pngLast, tidy up the splash screen.

 

Splash Screen

This is the pretty bit. First, let's get the graphics. Cut and paste the image into Paint.net and use the magic wand tool.

 

This selects a block of color that you can delete (make transparent). Delete anything else that you are going to replace. In this case, I deleted the progress, version, and link to the website.

Next we load this into our Splash Screen VI by Edit >> Import Picture to Clipboard... like this.

The progress indicator is simply a ring control made from a rotated metafile created in LibreOffice.

 

ProgressImpress.pngProgress.png

 

Green Screen Transparency

 

Now the clever bit is that we do not use the property FP.Transparency for this, as it's mostly for fading in and out. We're after a green-screen effect where the background colour is masked. For this we need to use some Windows functions.

 

User32.dll>>FindWindowA - Gets the window handle.

User32.dll>>GetWindowLongA - Retrieves information about the specified window. The function also retrieves the 32-bit (DWORD) value at the specified offset into the extra window memory. We're after extended windows styles.

User32.dll>>SetWindowLongA - Changes an attribute of the specified window. The function also sets the 32-bit (long) value at the specified offset into the extra window memory. The window is a layered window.

User32.dll>>SetLayeredWindowAttributes - Sets the opacity and transparency color key of a layered window.

So now you have no excuse for dull, rectangular LabVIEW!

free adjective \ˈfrē\ : not costing any money

If you look up the definition of “free” in Webster’s dictionary, there are 15 different variations – each with multiple sub-variations of the adjective. My initial thought is usually the first definition in the list, which I’ve referenced above. But other than the monetary definition, it can also mean free to be efficient, creative, and even error- or stress-free. And these days, it’s nice to have something useful that doesn’t cost a penny.

 

Simplifying your development is easy with  apps and add-ons from the LabVIEW Tools Network – no bargain hunting with this list. Just click, install, and go – for free!
