The "Execution Trace Toolkit" should help ID the issues. Lacking a screen shot of the TC Loop, I do not think I can add anything further. Have fun! Ben

Christian Altenbach started a "Rube Goldberg Code" thread in the BreakPoint of the NI-Developer Exchange and can be found at this link. http://forums.ni.com/ni/board/message?boar...4&jump=true Ben

There are a zillion things that can kill the determinism of a timed loop. Could you post images of the TC loop please? Wild guess? Are you using any pink clusters in the TC loop? Your diagram will help us help you! Ben

Hi Dave, See this thread form NI Dev-Exchange were I tried very hard not to cry. :headbang: http://forums.ni.com/ni/board/message?boar...d=22001#M171440 To properly support applications in multiple versions, you will need unique machines or you will have to get clever with booting and backups. I have frozen one machine at LV 7.1. I have another that is for LV 8+. Sorta looks like a set of big speakers. :thumbup: Ben

I added a Source Distribution to my project and used the "Source File Settings" page to set the password for the containing folder. After opening the NEW project and examining the "Source File Settings" I noticed a "secret" that distrubs me a little. I have been know to forget passwords, but I did not expect this kind of help. Has this already been discussed when I wasn't looking? If so, I would appreciate a link to enlighten me. I suppose i could just edit the project and delete the source distribution before sending to my customer. At the very least "YOU have been warned!" Ben

I have a customer who's spec read like that... To answer your question re:Changes Every release of LabVIEW comes with Release Notes and Upgrade Notes. While they do NOT cover every change, they do address the biggies. If you do not find what you need in those documents, then please post follow-up Q's regarding the specific feature and we will do our best to help. Ben

I am not sure if this is the correct place for this post but a power user rant seems appropriate Has anyone tried to apply a password to a hiarchy yet? If that isn't enough... Have you looked at the Source Code Distribution that is included in the new LV Project file produced? Ben (not tested in LV 8.20 )

Same here! The lack of visual feedback makes the user think the application is hung or not responding. Ben

Yikes! Talk about being on the horns of a dilema! Since I generally do not auto-index While Loops I'll leeve the "Show Constant folding" off and try to remember not to auto-index on while loops. Ben

Just an educated guess... "May the Schwartz be with you!" Ben

Lets see if I can give this a little spin the other way... Look at it from the point of view of the organization that offers the course. Lets ignore the cost of reloading all of the machine each time the course changes and keeping all of the hardware up to date and functioning. The NI course must be taught by CLD's or CLA's. Concider what CLD's and CLA's would make durring the same 40 hours if they were doing project work. With a full class room they may break even with what they would make if doing contract work. So the cost when compare to universities may be high, in effect, its a rather fair deal. Closing Q: Why do you think T/A's often teach undergrad courses? Ben

Yes the behaviour of the wires coming from my sub-VI's do that but I'd like to do it for the native LV operators. It would make creating sub-VI's easier as well becuase if we labeled the wires BEFORE the sub-VI was created, LV would label all of our controls and indicators automatically. Ben If I really wanted to get the name to show when floating that woudl work. BUT my thought was to provide a mechanism to improve the documentation of the diagram w/o making it more complicated. I can hear them asking already, "BEN, why did you convert to variant?". What I am thinking is to take the recomended free text we use to lable shift registers and wires, and actually associate the two. Ben

Seeing that Y'all have posted every possible correct answer to this Q, let me share what I thought the Q was by the title. The thought occured to me that that it could be much easier to indentify wires and tunnels (for the purpose of scripting) if I could apply a label to them. "On the surface" it would just look like improved documentation. But under the hood I'd like to be able to do an invoke node wire named tunnel to ... It would also be nice to be able label the outputs of nodes with proper names that would be displayed when we use help and the wiring tool while over the wire. Just a thought, Ben

Don't you hate it when procrastinating pays-off? :thumbup: How do you un-learn that leason ?! Ben

I agree and really hated this bug. This first tim eit hit it involved a cluster where I was limiting the history data loaded for a tag. Instead of loading the data for the last 24 hours, it loadd it FROMTHE BEGINNING OF TIME because istead bundling to the "start time" it was updating the Stop Time twice leaving the start time as 1904. For an application with 500+ VI that kept data from the time it was first started, this resulted in the application taking more time to boot each time it was started. It was only an error reported by VI Analyzer (Thank you Darren) that flaged my attention. At that time I attributed the error to myself. THe second time was a result of a customer calling my up after te4sting one of my changes and asking "BEN, did you even test this thing? It is displaying my RPM in the temperature field." Ben

I think the scroll bar was a sleeper becuase it was already possible to do that in prior versions. See this thread (on the NI Deve-Exchange) http://forums.ni.com/ni/board/message?boar...ssage.id=127096 starting at post # 17 we start talking about how to customize an array container to use a slider. Not as easy as LV 8 but still possible. And here is an even earlier posting by Jean-Pierre Drolet talking about the same trick. http://forums.ni.com/ni/board/message?boar...uireLogin=False Ben

I can not say that I have used the mixed signal graph yet. Most of projects require about 1 version of LV to to pass before the authorization for funding comes through. The good news is I have not heard about anyone bashing it. So there is a possibility that the following quote; "The problem with writing perfect code is, that if it is perfect, chances are that no one will ever see it." (BenNI) Ben

Being able to specify the time associated with a PV value would very helpful. I have written applications that continue to gather data (in cFP units) in the event the PC crashes. If DSC allowed me to specify the time, I'd be able to use Citadel to log my data. Lacking that functionality, I had to write my own version of Citadel from the ground up! On the other hand... I'm not sure how that would affect Citadel being 21-CFR-11 complient. Ben

Caveman: So why is satelite TV better than broadcast TV? Youngun: Instead of 3 channels you get 150 channels! Caveman: What is a channel? Reading the white paper on LabVOOP makes me feel like a caveman (or should that be cave bear ). Can anyone recomend a OO for dummies type book or tutorial? Ben

Yes indeed! Makes wonder what happened to the guy who was walking to the trash can. Did he ever make it? Did he fall in? Ben

Congratulations Mike! Ben

Why do I like these crash bugs so much? Another approach type casts as a string and then to the target class. This did NOT crash my machine and appeared to convert com3 and LPT1 OK. Thanks for sharing Mike! Ben

That was the case before the new versiobn of the course was offered. We taught that course for the first time (our first time) on July 11th. Now that the course is being taught, we should expect the test to change. Ben

I looked the results of an Express VI thing once and was convinced I could to do it better and faster without them. But on a related note... Express VI Development has been added to the "LabVIEW Advanced Application Development" course (i.e. the one origianlly developed by VIE) and had previous served as the source of the more advanced ideas required for the CLA. (Look what they've done to my song ma) So I am going to look closer at that material JUST TO PASS THE RE-TEST! Who knows, maybe I'll find something useful in there. Ben
