Hi, my problem is this. The vi tcp open connection keep opening connections on all the ports, incrementing the port with every run of the loop it's in, until it runs out of ports and claims that the "network adress is currently in use". I've used this vi, and it's "family" for some time, in the same configuration, and this problem never occured before. Any suggestions would be greatly apreciated.

Can you post the code so we can see how you are calling TCP Open Connection.vi

That worked great.

Thank you.

No Problem

Hi!

Thanks for the reply.

I have managed everything except changing one of the arrow sizes. If I use copy paste and resize outside labview, the new resized arrow does not rotate properly, it seems like it sticks to one point, (not the center). If I resize in labview both arrows get the same size

You can overlay a second gauge and make the background transparent and hide the scale. This is also useful if you want a 2 needle gauge with separate scales.

I started using TortoiseSVN only a month ago so I don't have alot of experience with it and I'm a bit scared now.. Anyone has the same behaviour ?

I'm still at 1.5.9, but thanks for the heads up!

I'm pretty sure the most advanced feature on that calculator is that you can type in "5318008" and turn it upside down.

That's awesome! I had forgotten about that "feature".

I am proud to admit that I bucked the geek train and refused to use an HP calculator in college. I had a Casio FX-6300G (http://www.rskey.org/detail.asp?manufacturer=Casio&model=fx-6300G).

I think I'd be more embarrassed about that than proud.

Awesome! I had an engraved name plate on my 48GX! I still contend the 48G series was the best graphing scientific calculator ever made (always bugged me that TI-85 was the standard in my high school). A few months back I reluctantly sold my 48GX, since I haven't used it since undergrad college. I sold it in 2008 for as much as I bought it for back in 1993!

I could have written the exact same post (except I sold mine in 2007 for more than I paid for it in 1993). The GX's are apparently still in high demand among land surveyors because they have some custom software that runs on them.

Somewhere there exists a video of me and a friend at a high-school pep assembly holding our 48GX's up to the microphone so the entire school can hear how we programmed the schools fight song into our calculators. It was a big hit...to our reputations. I wrote a note sequencer and my friend entered the song in a note,duration format.

That said, I'm not talking about the Serial Key (I've got one of those that covers everything) I'm talking about the activation codes since the development PC isn't connected to the internet

Ahh, now I understand. I had to go through that once and it is a bit of a pain. My keys all came through in one email though - a little nicer perhaps.

I enjoyed the show. Thanks!

They announced that there is not a singe CLA in the greater Seattle area - I guess I better start studying.

It looks like Alfa has been sending emails to Scott Adams

I do have a developer suite which on a SSP, and no. I don't get a single license for all the packages. Apprently thats only for a volume license agreement...I've tried!

You're getting screwed. I am not on a volume license and I have a single key that works for everything that comes with the LabVIEW Developer Suite + Automated Test Option + Machine Vision Option.

QUOTE (ShaunR @ Apr 11 2009, 05:07 AM)

Yeah. Just what I need. Another license key to add to the 25 I already have!

If you sign up for the developer suite you get a single license key for everything - including add-on packages. Then the only headache is remembering which products you actually have.

I don't like the cost. It's way to expensive. It's hard enough to convince the boss to keep up to date with the latest version of LV.

I couldn't agree more. And it's true that there is nothing that TestStand can do that you can't do in LabVIEW alone, but there is nothing LabVIEW can do that you can't do in C++ given enough time yet we all choose LabVIEW. It all comes down to how much of the wheel you need to reinvent. TestStand is way too expensive/complicated to use as a simple sequencer when a LabVIEW state machine could work just as well. But when you get into database logging, report generation, conditional looping, etc. TestStand starts looking a little better.

I actually argued the case for doing our new internal test architecture in LabVIEW alone, but I was the new guy and lost so we went with LabVIEW + TestStand. I am seeing the benifits now, but given the amount of time it took us to learn TestStand and customize it to our needs, I still think I could have made a pretty robust executive.

QUOTE (jcarmody @ Apr 10 2009, 12:09 PM)

I can't get past the feeling that it's just another text-based mess.

What do you mean? There is nothing text based about creating a test in TestStand.

Where TestStand has proven useful for us is in reducing the time it takes to create tests for new devices. The TestStand process model is customized to our data collection system, our report generation system, our failure tracking system, etc. None of this changes from one device to the next. We maintain a library of common modules (done mostly in LabVIEW) that can be reused for multiple products. When it comes time to create a test system for a new DMM, we write the DMM driver (again in LabVIEW) and then it's just a matter of dropping the test VIs into a new sequence file in the right order and setting the limits. The new driver handles communication with the UUT, and once we get the data out we can run it into our standard test VIs (DC Voltage, AC voltage, Capacitance, etc.). We don't have to worry about logging data for each step, or generating a calibration certificate for each UUT because TestStand does all of that for us (based on the process model that we developed once).

Go to Configure --> Station Options --> Model Tab and browse to ParallelModel.seq. Now click Execute --> Test UUTs and you'll see how it works with multiple units.

TestStand is very powerful, but the learning curve is steep (especially for parallel testing) and there is the added cost of software + deployment licenses. If you already have a system that is working, I don't think I'd invest the time and money for TestStand, but if you're looking to upgrade your systems anyway TestStand might be the way to go.

Thanks for the tab suggestion

I will also have a look at md5 hash to avoid storing the password in the LV source.

An other good idea could be to use an ini file to store password(s) hash(s)

This is a little program I threw together quite a while ago. A friend wanted a way to quickly launch sound files. It has some really simple resize code in it that hides the configuration area when not needed. It's not very pretty, but it might help.

It's numeric roundoff due to floating point imprecision

As type double, 0.08 entered becomes 0.0800000000000000017, increment up, you get 0.160000000000000003. Increment up again you get 0.239999999999999991 - now, when you increment down you get 0.159999999999999976 and you can't step down another 0.08 and stilll be above the allowed minimum

Mark

Thanks Mark. I figured it was something like this. It seems to me like it should do the math first and then coerce to the nearest "in-range" value though.

I don't know if this is a bug or if I'm missing something (maybe a rounding issue)...

1. Place a numeric control on the Front Panel
   
2. On the Data Entry tab of the properties window, uncheck Use Default Limits
   
3. Set Minimun to 0.08 (coerce), Maximum to 2.0 (coerce), Increment to 0.08 (coerce to nearest) and click OK
   
4. Type 0 into the control and it should coerce to 0.08
   
5. Now use the increment/decrement arrows to adjust the value. Once you get to 0.24 or above, it is not possible to decrement below 0.16
   

I would expect to be able to step back down to 0.08. Does anyone have an explanation for this? Should I file a bug report? This happens on 8.5.1 and 8.6.1f1

Thanks,

Toby

Thanks for the link Norm:

That's hilarious!

I could see a use for this in our operations, but what does it mean when it says, " Limited functionality with Windows NT 4 and Vista." We use Vista quite a bit.

Note: CDW has it listed above MSRP!

I'm in love Norm. This is great! I just have a crappy desktop microphone and it picks up every command. I was talking to a coworker and happened to say "replace" during my normal conversation and up pops the dialog box to choose a new control.

Very cool! :thumbup:

QUOTE (Steen Schmidt @ Apr 1 2009, 02:30 AM)

Since so much focus is on multicore and parallelism today, isn't it time for a true parallel For-loop structure? I know the compiler reputedly has some capability for unrolling unrelated cycles in a For-loop, but I still haven't seen any real-life cases of tangible performance gains from this. I often encounter For-loops with a dynamic number of cycles, but where each cycle is unrelated to the others (initialization of N instruments for instance, where N is only known at runtime). I'd like to see an option in the context menu of a For-loop saying something like "Run in parallel if possible". This would defeat shift register capability of course, among other things.

I think now would be a good time to recommend that you sign up for the http://www.ni.com/beta' target="_blank">LabVIEW beta program. :ninja:

QUOTE (zmarcoz @ Mar 25 2009, 11:23 AM)

Dear all,

Could someone please share the experience? I have submit more than 1000, and I only get one face to face interview. On the other hand, If you are a boss, how would you think of a person study for long time and without industrial experience? Moreover, how would you think about a person only have a temporary status to work even if he claims that he does not need sponsorship and will get green card ?

Thanks

If I had submitted 1000 resumes and only had one interview, I would start asking myself what I'm doing wrong (I would have started asking after about 25 submissions to be honest). Is your resume professional and concise? Are you applying to jobs that you are actually qualified for (All your degrees are nice, but they don't automatically qualify you for senior level positions)? Do you apply with a personalized resume and cover letter or are you blanketing monster.com with 100 applications at a time? If someone Googles your name are they going to find information that could turn them off towards you, like a myspace account with a picture of you taking a bong hit (this actually happened with a guy that we were ready to bring in for an interview).

Personally, I would not interview someone who only had temporary work status unless they were the only qualified candidate or unless I was prepared to sponsor them. It is costly for a company to hire and train a new employee only to find out that for some reason their green card was denied and they have to return to their country of origin.
