" What's the thought process behind your rule-of thumb?"

well, i think all has been said...

cause i'm using lots of references (access is deeply nested inside the hierachy) i'm using a naming convention for controls that allows me to find the purpose of a control by its label. these labels are for sure not suitable for the common user of the app, so for the GUI i'm using the captions. i'm writing the code (and so the labels) in english while the GUI is in german (or any other language).

btw.: jwdz, has your question been answered?:-)

Hi Chilly, I looked at the 'race condition.vi' and I have a comment.  Perhaps I'm a bit confused, but I don't think that's a demonstration of race conditions.  I think that it is a demonstration of how/when locals are written to and read from.  That code produces the same result every time, and it's just a bad way to code it, but I don't think it's a race condition.

your thoughts?

Now I have no formal prigramming training, but for me

"I think that it is a demonstration of how/when locals are written to and read from."

fits my description of a race condition......

Who said race conditions need not be reproducible?

Shane,

No one..    That's why (certain) race conditions can / may cause unpredictable results.

I agree!

I often review code developed by LV novices. As soon as I hear "sometimes", "occasionally", "not always" I go looking for race conditions which or almost always solved with a proper action engine.

My response is based on this definition of a race condition:
http://searchstorage.techtarget.com/sDefinition/0,,sid5_gci871100,00.html
and though it's not worth arguing about, I still think that this gives predictable/reproducable results every time and is not a good example of a race condition.

anyway - it's not a good way to do something, but maybe I need to broaden my definition of "race condition"

Hi -z,

I agree that CC example was predicable. Here is an other example that I believe is predicatably-unpredicable.

haha-- nice one Ben!  That is just ridiculous to even look at! BUT - that is a great example of a race condition!
