Hey! I just got the results from my CLA re-certification. I passed again!

CLA recert? I thought once you got up to that level, you were part of the elite and there weren't any more stinkin' re-certs... guess that was just a legend I heard.

Anyway...Way to go, Omar!!! http://forums.lavag.org/index.php?act=attach&type=post&id=6186 Good job, Michael!!! http://forums.lavag.org/index.php?act=attach&type=post&id=6187

I'm still on the fence on this step of my journey to the Wonderful World of LV. I'll probably wait until after the summer if I do decide to "follow the yellow primative icon" and plunge into the CLA cert.

As long as there aren't any purple horses or big shouting heads in the exam...

What exactly does that funky-looking string refer to?

Refer to the help for "Match Pattern, special characters" for a lot more info

Looks like Justin beat me to it, and he is correct in that "^.+" means: "Match any one or more characters at the start of the string", which will give you any match that isn't empty. The only reason I had to do that is that the Find utility in LabVIEW doesn't allow you to search for empty matches (which would be useful here!).

And yes, this will search the tips as well.

If you just want to save this data in a file and retrieve it later, then flattening to an XML format may prove useful.

One last stipulation, the conversion of a Numeric must result in a string that appears exactly as the number appears in its Numeric control, not any different format.

Using a typedef cluster as I did above, the display format is saved for you in a .ctl file, so you needn't worry about the text file holding the formatting.

Hope this helps

I was just thinking it would be nice if a wire or other BD object had a slightly different appearance to indicate whether there is a Description and/or Tip associated with it.

Does LabVIEW 8.x do this?

Thanks,

Gary

No, LV 8.x BD objects look identical whether or not they have a description and/or tip. There are a few ways you can get this information though.

1) If you have the context help on, you can mouse over the objects and see the descriptions

2) If you do a find/replace with a regular expression of "^.+" (without the quotes) and filter just on the front panel and description (under more options), you can see which objects have anything in their descriptions or tips.

3) Programmatically, you could list them by checking for an empty string in the "Description" or "Tip Strip" properties.

Hope this helps.

Congratulations orko! Ready for the CLA?

I'm ready to give it a shot (and willing!!!), but unfortunately my current employer doesn't see any real benefit from that level of certification at this time. There just aren't any projects we're working on that would be in need of a LabVIEW architect overseeing a group of CLDs (unless you count overseeing myself). :headbang:

Assuming I ever get the opportunity though (it probably would be out of my own pocket)... I would love to hear of people's experiences (nothing breaking the NDA of course).

I'm especially interested in what people *expected* versus what they *experienced* when they took the CLA exam. I've been through many LabVIEW related courses now (Basics, Int, Adv, DAQ, RF), acheived CLAD & then CLD certifications, and now I'm reading through the PDF describing the requirements of the exam....and I still don't feel I have a good grasp of what the exam will actually be like. Descriptions are okay, but an official sample or a prep course (like they do for the CLD cert) just aren't available it seems...

what was your project?

I don't believe we can discuss too much about what our project was, so I'll just say that mine resembled the http://zone.ni.com/devzone/cda/epd/p/id/1683' target="_blank">Car Wash sample exam that NI gives for CLD preparation. There were several differences of course, but I can't stress how much going through the sample exams and the CLD preparation course helped to prepare me for this exam.

It's all about speed, and to be fast you have to have already hammered through some similar situations before you sit down to take the exam. The samples helped me out.... a lot.

2) What did improve launch time a lot for me is frequent background defragmentations. I use a deframgmenter that once a week do a deep defragmentation that put the most used application on the fastest access location of the HD (or something like that). This make a very signifiant difference. As you can see in my stat I dont use LV 7.1 much anymore and its start time is pretty slow now.

This is no joke. I just went through a disk cleanup* and defrag (used the O&O defrag trial) and my launch time of LV8.2.1 after reboot went from 32 seconds to 23! Granted, the other versions of LabVIEW probably would have also sped up, so it doesn't improve the relative benchmarks... but I'm much happier as a result. Good tip! :thumbup:

(*) as a side comment/tip, I never really liked using the XP disk cleanup tool, since it always hangs up for a long time on the "compress old files" analysis (especially since I never compress old files). Very annoying. I just found an awesome tip however from one of the knowledge bases that takes care of that little problem! http://support.microsoft.com/default.aspx?scid=kb;en-us;812248' target="_blank">KB812248 ... it now takes literally seconds to scan and clean up my old junk files!

I feel your pain...

If you have a good grasp of state machines and timing, and are quick at looking at a problem and diving into the solution, you'll be fine. Oh, and make sure to document everything!

I took the CLD prep course before I took mine (last Thursday, May 10th) and I believe that helped out a lot. Make sure to go through all of the CLD sample exams, that saved me a lot of design time on the exam.

QUOTE(ohiofudu @ May 15 2007, 09:23 AM)

Be ready to encounter some qustion that are not in the web Exam,and some tricky question.

I found that there were a number of questions on the CLAD that required you to really *read* the text/block diagram (more than once!) to not get tricked into the wrong answer. Be very careful when presented with a question that seems "way too easy". Also be aware that there may be questions that are very similar to the CLAD prep exam, but not necessarily exactly the same...

I also found that the hour that they gave me was plenty of time (I finished up with 20 minutes to spare) so make sure (if you are taking the computer based exam) that you mark any questions that you aren't 100% sure of as "review" with that little checkbox. That way you can carefully go over them at the end and catch all of those "tricky" questions.

Good luck!

Joe

THANKS!

Hello LAVA,

While I'm sitting here biting my nails waiting for the results of my CLD test, I was very impatiently wondering...

I've heard from several posts here and in the NI forums that failing the first time was not unheard of. How many times did it take you (people that took the CLD exam and passed it eventually) to become certified? I feel that if more people knew the "track record" of the CLD (heck, even the CLAD or CLA exams!) the level of nervousnous might go down just a *wee* bit.

Feedback node was fastest, while loop second and for loop last.

Now *that* is interesting... Seeming that this is the first time I've heard of the feedback node method for LV2 globals, the question I have is are there any drawbacks or perhaps other advantages to using it other than speed? And what of the warning dialog that beckerg noticed?

The feedback node is something that was covered way back in the Basics course, but I honestly never really found a practical use for it (yet). This seems like it might be useful, but I want to make sure that there isn't something that I should watch out for.

Thanks!

At level 14, there are multiple destination pipes. It appears to me that one of these pipes is a real destination, and the other is a fake and if you route the water to the wrong pipe, you lose the game. Is there any way to distinguish the real destination from the false destination? Is it random which is the real one, or is it always the same one and you just have to learn which is the real destination at each level and remember the next time you play?

Well I just tried it and reached level 14, and was thinking that the multiple outlets that appear after that were all just different paths you could choose...but evidently chose a "fake" one in level 17 and game over.

I don't think there is a way to tell the fake from the real (I was looking at them pretty closely and they looked identical). But I wouldn't be surprised if the "right" one stays in the same location every time you reach that level again. Just a hunch.
