At the risk of starting the whole By-Val/By-Ref debate (or should i say rant(s) ;-) ) I really dont want this topic to degrade into that debate again as I think it has been well covered , how are you guys implementing By-Ref ? I have been using both a single element Queue with the Check-in/Out methods , and , I also have tried making a VI Ref an element of the class and use Set/Get control values methods to access any control owned by the VI...

Good idea!

I have made that very suggestion in all the Beta programs i have been in , but , the payoff for NI probably doesnt warrant the work to change every boolean operation to accept the error cluster, especially since it isnt such a big deal to insert the unbundle by name , but , damn'it , us programmers are lazy by nature , and thats one of the reasons we use LabVIEW ;-)

The inability to close the .ctl window is a new one. I haven't heard of that before. If you can get it reproducible, please post it to ni.com so it gets investigated and CAR'd.

I had this same thing happen last week , i will see if i can reproduce it.....

DO NOT click on the links to the screenshots; they point at a website in a foreign language, and not at full-size images. Reported to the moderator.

if you click on the text part of the link wher eit says Reduced: blah blah blah you get the screenshots , if you click on the image of the screen shot yes you go to a foreign language site....

As some of you may recall I was complaining a little last week that my Dev Suite est. ship date was January 22nd , I was told they were waiting for a driver , I guess this must be what the issue was all about. Well they shipped the Dev Suite with the 4th quarter DVD/CD's which arrived on Monday which I installed and now have an "infected" system , although I should be ok with what I am currently working on....

I recieved the "PRODUCT NOTICE: Software problem may corrupt configuration in MAX" email yesterday about noon from NationalInstruments@demand.ni.com

I have been asking for real Child Windows for years ….. there are VI’s to do it , but , it would be nice to have the native ability….

Greg M. at NI told me years ago why they didn’t want to go down that road but I forget what the reasoning was…

also i think Stephen pointed out that they tried to use child windows within the project during the last Beta and it was quickly shot down , i liked the idea... but sadly it went away....

I have an idea, come to Australia and order it here; I got my 3 versions from between 3 days to 1 week :-)

But it could also be so that they have stopped shipping LV 8.5, and waiting for the next release….you never know

//Mikael

Well what do you know , when i checked my email this morning i had an email from NI confirming that my order was shipped....

man i wanted to go to Australia ....

I like that idea.....

I was told on the phone that they were waiting on a driver before they will ship.....

but with Pro activated on my machine I should be all set now....

Actually i got to thinking....

When LabVIEW installs it actually installs the Pro version but your S/N and activation code open what it is licensed for , so i called NI and they activated mine for Pro , so now i am all set to go ahead and mess around with the XControls etc....

You could ask your Sales Rep. They can most likely help you out before late January.

i might have to go that route.....

QUOTE(crelf @ Dec 6 2007, 11:26 AM)

You should be able to download it and register it using a serial that NI gives you - you don't have to wait for the physical disks. You can even use it in eval mode for 30 days or so until you can convince them to give you your serial.

I looked around and couldnt find anywhere to download a trial version of LV Pro.... maybe i missed it ....

Earlier this week i ordered the NI Developer Suite , when the order was complete they gave me an estimated ship date of January 22nd ?!?!??! I can understand with hardware that there may be long lead times , but , it seems to me that software shouldnt really have these long lead times.... i was hoping to get my hands on it as i am anxious to try XControls with my latest project :-(

oh well , guess i will have to wait until the next project....

I have a problem and I hope someone can help me out here.... We went to a customer site and took data with our laser vibrometer , I wrote a VI to do some initial analysis on the data to get the power spectrum and PSD of our data. Since this is our first foray into this vibration analysis the higher ups asked me to get a second opinion to help confirm that we are doing it correctly etc... we'll the company that agreed to help us emailed me over the weekend and indicated they can't help us... Is there anyone who has experience in this field who could analyze some of the data and see if we are close ? the data from the laser is in velocity.

Thanks

I was just wondering how many people are in the SETI 'program' (http://setiathome.berkeley.edu/)? maybe if there is enough we could start a LAVA team (with Michael's permission)....

Dan

Has anyone installed 8.5 and the device drivers on a system that also had 7.1 w/drivers ? if so did it remove the device drivers from 7.1 , if so whats the fix ?

Thanks

Dan

We are setting up a laptop to do DAQ and analysis at customer sites. it appears that we will be doing DAQ on a couple of channels at up to 50 Khz/Channel in conjunction with streaming images from a thermal imaging camera via firewire. Anyone have any experience with this sort of stuff on laptops ? I am looking at a couple of laptops one is a Panasonic Toughbook 30 1.6Ghz and the other is a Dell Latitude ATG D630 2 Ghz , both will be configured with at least 1Gb of RAM and ~100Gb HD's. Will these machines be powerful enough to handle the DAQ and Firewire streams ?

thanks

For debugging and testing purposes, I would like to be able to have my VI programmatically tell itself if it is running as a VI in the Labview development environment or if it is as a built application?

Currently, I am using a simple case statement with boolean constant to control this feature.

John

try using the Application Property "App.Kind" wire that to your case(s)

Dan,

You have been creating test and automation applications in LabVIEW for years! I've seen your name countless time on this forum and on Info-LabVIEW. You should have plenty to show. Wait, did you switch companies? Last time I checked you were at Stoneridge. We've built several test systems for Hi-Stat here in Florida. All of them are LabVIEW based. (of course).

Perhaps the best approach if your boss doesn't know anything about LabVIEW would be to open up the pallets with all the analysis functions. Explain that most of that would have to be programmed and integrated from scratch in some text language. Of course, you can use third party libraries in text-world, but that takes time to understand and debug too.

Good luck!

Dan

Yes i have been at this LabVIEW stuff for a long time and there are all kinds of examples around here in the lab , but , it doesnt seem to be good enough for them.... actually its the guys in Sarasota that say they dont (or dont want to) use LabVIEW , or at least it was explained to me that way. And since the same guy is over us and them he wants to standardize operations etc... so I was hoping that maybe someone had a good presentation put together , although it would almost be an endless presentation to go into everything , I am probably going to end up walking him through the lab and explaining what all we have done with it and what all i would like to see done yet.

Dan

Maybe someone a suggestion here ..... I have to explain to my bosses

boss what "ALL" LabVIEW can do , which is sort of impossible , I have

looked at some of the stuff online and I don't think it is in depth

enough , I actually don't like the heavy reliance on the Express stuff

!!! He started mumbling something about C/C# and .NET which scares me a

little.... One of our other facilities is pushing flukes NetDAQ

software/hardware stuff , but it really is just for data collection

etc...=20 I am sure others have been through this same issue.....

Suggestions ?

Thanks

Dan

we are in need of a rugged laptop or two that will be traveling with engineers around the country and the world at times.... they will be doing data acquisition and some serial (rs-232) stuff mainly...

anyone have any suggestions ?

thanks

I am not, but have always wanted to go. Good to see open wheel back to Mid-Ohio. I like the IRL move to road coarses. Those street parades (St. Petersburg) - I could do without. I just noticed that it is an IRL/ALMS weekend. Should be great.

yes the move to road courses is a good start to getting both series (IRL and Champ Car)back together , but , i doubt it will ever really happen , as you said it is great to have th indy cars back at Mid Ohio , although Mid Ohio repaved the track last year for the bikes , they took all the concrete off the corners , the concrete was there because the indy cars pushed all the asphalt to the outside... i am fortunate to have Mid Ohio so close , i work about a mile from the track , if i stick my head out the window i can hear the cars... i live about 8 miles from the track and i can hear them there too... i have been out there for all the public races so far this year... it is going to be a busy three weeks , have the IRL/American Lemans this weekend , next weekend is the Vintage Motorcycle Days and the following weekend is Honda Super Cycle , then i get a break until mid september....

Dan

By any chance is anyone going to be going to Mid Ohio this weekend for the IRL race ?? this is the first time that IRL has raced a road course i believe (or one of few)...

Dan

Does anyone have any information regarding this company ? we were doing business with them and they have disappeared. The phone number (401) 724-0306 has been disconnected and there is no response to emails.

Check out the example of how to use annotations on a graph.

I thought this was pretty cool when I first learned of it.

Thanks for the input , after looking into this a little more i have decided to just run with the picture control as i also need to change the bar colors depending on the value...

Have a Great Weekend

Dan

I have to generate some bar graphs that have text as the markers and they have to be vertically aligned under each bar.... a quick check of the graphs i didnt see an easy way to do it. i am looking into using a picture control.... is there an easier/better way ? i hope i am overlooking something...
