Excepting some Controls (and Indicators) while Initializing whole VI controls and indicators to default

Need arises that sometimes you re-initialize values of everything in a VI to their default values. However, you just need to leave value of few controls and indicators as is. The above diagram explains how to do it. Use a sequence structure with 3 frames. Variables of those controls and indicators are placed in 'Read from' mode in the first frame. Variables of same controls and indicators are placed in 'Write to' mode in 3rd frame. The variables are wired through the second frame (using tunnels). The Invoke method node for re-initializing all values of the VI to default is placed in the 2nd frame. Like it? Drop a comment!

LabVIEW Tutorial - Tips and tricks I did not find elsewhere...

Greetings!

I'm sure you are in love with LabVIEW as I'm since using it for the first time in 2001. LabVIEW developers and consultants from all around the world have contributed with LabVIEW examples, tutorials, excerpts from their LabVIEW development, express VI and a host of other resources to the web. And the free LabVIEW Support & Help from National Instruments and their online forum is superb. Then why another blog on LabVIEW training?

The reason is, while I used the examples from other LabVIEW programmers & support from LabVIEW forum, there are certain things I learnt myself while faced with specific LabVIEW programming tasks. And I just thought it would be great to post it here so that other developers like you do not have to spend the time I did.

Also, I'm posting here a very simple LabVIEW tutorial that requires no programming background. Something that a 7th grader can understand and jumpstart with LabVIEW...

And yes, it goes without saying, I'll appreciate your comments and feed-back of your own LabVIEW programming experience. Feel free to contact me! Let us share our knowledge for mutual benefit.
