Things a LabVIEW Programmer must know

Hello guys..
I am working on labVIEW for last 1 year on my own.
If I get any difficulties I post my questions on the NI Forum.
But I only know a small drop of the sea water..
So what should a labview programmer must know??
Solved!
Go to Solution.

In short, how to avoid 10 screen wide spaghetti code full of sequence structures, local variables and race conditions
Also I advice you to have a look on the NI Certificates and the "learning curve":
http://www.ni.com/white-paper/13120/en/
http://www.ni.com/training/certification/
http://forums.ni.com/t5/Certification/bd-p/Certification
edit: maybe I would just add a few points which I usually keep in mind during planning phase of a new project:
choose the right framework or template based on the requirements
Keep in mind how to get and set values - indicators and controls. If it is possible, use the wire to pass data. Keep in mind what is OK to do with local variables (for example update a control), and what should be (usually) avoided (read/write indicators for example). If you cannot use the wire to directly pass info (parallel loops), learn proper use of Notifiers, Queues, UserEvents, etc...
who will use the code (this is very important, you need totally different approach if you develop for only yourself, or for others who are not programmers and maybe even do not know the hardware part of the system...)
GUI most be always responsible. Avoid bad habits (longer time running things in GUI Event loop).
Avoid overcrowded Front Panel: use pop up windows for settings, etc. Which the user do not need to see always.
Error handling! It is very important to make a robust proper error handling strategy: for example if one of your HW component creates an error, your application cannot just stop simply. Handle the error, properly close all HW and File references (remember if you do not close a File properly, you can lose LOTS of data&colon; file writing is buffered from RAM). Also log the error info in a log file.
If you need to make an EXE or installer: use a configuration file to store user changes: if the user changed the colours (width, etc.) of a Graph/Chart, store this info in a config file which you load at the next application start.
Autodetect hardware (or give the user the option to change port/channel settings): what happens if your application moves to another PC (COM port numbering changes, etc...)? Your application need to adapt to HW changes.

Changing a software into a Labview Programme

Hi all,
I am new to LabView and would like some help in changing a software into a Labview Programme.
The PC software is a platform that enables a PC to control a R/C transmitter. It is written in C# therefore I need to change it into LabView for my project.
For more information about the software you can download it from the following link: (http://www.min.at/prinz/?x=entry:entry130721-182227)
It is under the PC control software section.
Thanks for all the help!!!

Welcome to my world.
I have been working on a project (not a school project, a work project) for a while now to emulate a set of C/LabWindows programs to LabVIEW.
"Why?" RavensFan asks. Because the software on the instruments we build needs rapid updating as the instruments are updated, doing this in C is always a major task (it is thought that using LabVIEW should [eventually] be quicker and less prone to error), and we are a small company which cannot afford the luxury of a staff of C and/or LabWindows programmers.
But what RavensFan says is true. You have to figure out exactly what the C# program does and how to do the same thing in LabVIEW. You cannot do a transliteration by any means, it will come out like some of those old Japanese instrument manuals transliterated into English, and have just about as much use (i.e., none). But you have at least one thing in your favor, quite a bit of the C# code functionality can be replaced with very simple LabVIEW code.
As to understanding the C# code, well, you just might have to grab one of your buddies and bribe him with pizza (the Universal Currency for students) to walk through it with you until you can understand the flow of the program. This may take more than one pizza and/or night.
One thing, remember to make your LabVIEW code modular (i.e., using subVIs for common tasks) so you can (1) fix one bug and have it corrected in many places at once, and (2) build VIs which don't take up acres of screen real estate - there is little that is so frustrating (to me, anyway) as having to skip back and forth over a 9000x2600 pixel screen to troubleshoot code.
Best of luck,
Cameron
To err is human, but to really foul it up requires a computer.
The optimist believes we are in the best of all possible worlds - the pessimist fears this is true.
Profanity is the one language all programmers know best.
An expert is someone who has made all the possible mistakes.

How to start a second labview programme automatically when first programme is aborted ?

Hi,
I have two independent labview programme. I want to run one programme at first. Second programme should start automatically if first programme is aborted by clicking abort button. Could you please help me in this regard.
Thanks

Would it not be better to close the meters when you close the application and have your application exit gracefully rather than having it start another one?
(You can call an executable from within LabVIEW using the System Exec VI but I don't think you need that here)

It sounds like you have solid experience. Have you considered contract work? The job market kinda sucks right now. Check out net-temps.com and jobcircle.com. Presently I work through a contract house called YOH Scientific, yohscientific.com in Newark, DE. I'm sure they could find you work but they'll skim a lot off the top. I worked with optical comm when I lived in Mass. Too bad it took a dive. I still see a lot of opportunities for RF comm in southern New Jersey. They usually want LabWindows/CVI. Since you know c/c++, LW/cvi would be a cake walk for you.
