Philip's LabVIEW Quick Start

[IowaPhilip]

Hello. I am preparing to teach LabVIEW to talented high school students this summer.

I prepared a one-page "Quick Start" that aims to introduce LabVIEW fundamentals. In a spirit of collaboration, I hope you find it useful.

Find it here: Philip's LabVIEW Quick Start.

A Common cross-post method is to note where else the post is(with link) and then duplicate the post in both locations.

WHY? many forum users are in the office or only have access to one forum (In my case I have a firewall blocking Mindstorms/Education forum today and cannot see your content)

[IowaPhilip]

Thanks. I added the cross-links.

In Datatypes, you say booleans are dotted black.  They are actually a dotted green line.

In error detection, usually VI's or functions will not execute if there is an error on the error input wire.  But there are some exceptions, generally for VI's or functions that close resources.  They will still execute even if there is an error.

Hi Ravens Fan,
I wonder which function will execute even if there is any error because till now I was expecting any function will never execute if there is any error in its input but your point made me to know what are those VIs and its seems interesting so if you can give a link where those things are documented then it would be much helpful for everyone.
Thanks

Read this idea and vote for it if you like it.  Visual indication that VI will run even on error.

You need to look at the detailed help for the function to determine if it will run on error or not.

In general, the "Close" type of functions will run even with an error, while most functions will not execute (other than passing on the error and outputting default values on its connectors.)

That idea also links to Darren's nugget Darren's Weekly Nugget 06/07/2010 which discusses the error in functionality.

[MoReese]

Well, the obvious ones that will run on error are the ones intended to show those errors, i.e. Simple and General error handlers.  But again, that should be obvious.

[P@Anand]

Yes I welcome the Idea. Because it explicitly shows which function/VI will run even there is an error at its input. Also its not an easy job to read the help file of each fucntion to check whether it will run if an error occurred.

Thanks, Ravens Fan. I fixed both of your findings.

LV trivia:

You can right-click on a property node and choose "ignore preceeding errors". There will be a small change in the look of the property node to alert you about that option.
