    hi all

    QUOTE(WangBogle @ Sep 28 2007, 10:42 AM) Hi Wang. i love it!
  2. QUOTE(Ben @ Sep 27 2007, 10:13 PM) Ben, you just saved me so much time you should be rewarded! :worship: whenever i meet you, its a promised beer (a good, real bavarian weizen beer!). one of my biggest trouble when i develop is that i create lots of "test version" subvis, and only one becomes (associated with its sub-sub-vis) the "used" one. i spend so much time cleaning the folders it is unbelievable :headbang: . ps. i love the emoticons here...we should transfer them to the NI forum
  3. QUOTE(yen @ Sep 27 2007, 08:07 PM) yep. thats the way i do it, when i get too many shift registers...it looks always a little mistical too
  4. QUOTE(Ben @ Sep 27 2007, 08:15 PM) well, when i need to distribute, i generally do so within a llb (custom ->llb). otherwise i keep the project as is. is there any advantage to distribute while preserving hierarchy? why not just give the full project?

    congratulations ! :thumbup: very much good luck. i hate my IT department as well, i cant have normal access to even my own computer! :headbang: talk about resetting configuration for LV every time they shut down power...
  6. Hello Watcher, Welcome and enjoy! on top of the "normal" Labview Forum, you could look at the LAVA WIKI Also, for getting a fast track to some of the more advanced stuff of LV, as well as nice shortcuts, you can browse trough the Darrens weekly nuggets. they begin as simple nuggets, but some stuff there get really advanced, and all are extremely usefull. as you learn them you will discover your learning curve to shorten quite a bit
  7. very informative thank you. i always wanted units with the indicator
  8. Kevin, thansk for your implementation. yes it works this way, but given the complications, its attractivness is decreasing exponentially. Mross, as you and Kevin says, polling will be easier in this case. but all in all, my goal was to change notifiers to occurences. i guess i will stick with notifiers. Aristos and Roflk: my main concern with the notifier, is just the fact that if one of the notifiers is released, the "wait on multiple" stop waiting and release an error (on top of the fact that graphically the occurence+ wire is a little more compact). but at this point you are right it doesnt worth reinventing the loop (hem.. the wheel) when one has notifiers so cool Thanks everybody for your toughts and help !
  9. well i'm using notifiers quite a bit .i just love notifiers and queues . there is something in the idea that you can put in, and retrive, data from somewhere in the computer universe, that just make me feel good. anyway, i find notifiers extremely usefull in producer/consumer loops, or master slave configurations. however, i saw the other day on NI forum somebody trying to pause a DAQ loop, from an event structure. that made me wonder if i could pause the whole loop !, optimising CPU for other apps in the program, like analysis. so in the state machine loop, there would be a pause state, driven by one or several notifiers. as i said before, notifiers still have some disadvantages, when the sole purpose is to notify. the occurences are just better elements for that - in case one could have a function like "wait on multiple occurences".
  10. i liked best this one. shows the essence of the problem with Windows
  11. thanks for your response. my request has two main reasons: 1) mainly aestetical. i am looking for an equivalent function to "wait on notification from multiple", in situations i do not need to pass data, yet has to wait on one from multiple notifications. 2) added funtionality: the wait on notification release an error if one of the notifiers is released. by definition the occurences do not get released. that avoids getting an error and a "stop waiting".
  12. QUOTE(Kevin P @ Sep 19 2007, 05:04 PM) i tried the polling option (was my first approach too), but did not like it at all, as it stalled the rest of the software. the whole idea of waiting on occurence is that there is no cpu overhead.for solution 2: do you mean an occurence that could be fed by two occurence generators? i am not following QUOTE(mross @ Sep 19 2007, 05:12 PM) Since you haven't shown your VI it is hard to say much.I wonder why you have notifiers at all. It is extremely easy to check two values inside a while loop, put the values in a shift register, next time the loop runs see if the new values are different, if one has changed (or by whatever logic you desire) then do some specific action pertinent to that logical conclusion. I would say in general you do do not want to use notifiers if a more conventional method works.Mike we must be talking about something else. the idea of "wait on notification", or of occurence, is that the piece of software (the loop), is paused until released.
  13. QUOTE(Jim Kring @ Sep 19 2007, 03:56 PM) Cool i just had this discussion yesterday with a colleague. he kept telling that you can easily program c++ to process parallel, and that Labview is just annoying because one cannot easily access core functionnality. the "i want every option" guy. Fact is, he never actually passed beyond the beginner utilisation of LV. THat is to say, there must be a way to publish LV as a real functional programming language. Yet, when one think of doing 3D apps or games, LV is just not fit for the task. so, maybe if we had features like 1) a different kind, more efficient compiler - one that would not be "instantaneous", yet would make code run much faster. 2) a runtime engine preinstalled in the operating system(s). we could explain and share it better?
  14. I tought this question fits better here than on the NI forum. Lets say i have a situation with both a notifier and an occurence wait (or for that matter, two unrelated occurence wait). I want my piece of software to perform if either one of them has returned a value. the only way i found to do it is to use the "wait on notification from multiple", but it doesnt always fits my needs (mainly because some software i have already has occurences...) any idea?
  15. QUOTE(PaulG. @ Sep 18 2007, 10:52 PM) hum, you dont wanna do that: i tried it (stupid me), and my self built PID for regulating the temperature didnt work well ( ihad no display of actual T, and did not check out, only at install...). so when the computer was working, it was no problem (just way not efficient enough, even for a relatively big stack - PID never got to desired range). as i turned down the computer, T went below ice freezing (power supply unit always on, and obviously PID overshoot...). so, when i turned it back on, i got after about 10min a nice burning smell, along with some firworks of the capacitors. the motherboard still works, but gets very very hot. i trashed it. :headbang:
  16. QUOTE(Aristos Queue @ Sep 13 2007, 08:29 PM) Would be even slower if one would implement an exponentially decaying treshold, which would depend on the last nb that came out of the array i love it. alough the queue is a tough competitor :worship:
  17. It seems to me that a CRIO system would perfectly match your requirements. and you can add elements (expandable). and it is relatively cheap. some of them include USB on top of LAN. i liked it. another solution i have seen once is the utilisation of a PXI rack. this is a beauty, but i expect the price to be real steep. it include full computer embeded as a PXI box, has all connections in front for easy access, and look very professional

    QUOTE(yen @ Sep 16 2007, 07:52 PM) Thanks actually i am thinking of coming visiting there in mid-october. something related to good food, see and sun i grew tired of the Kartofell und Shwein they have over here - and the summer was so rainy my skin turned yellow

    Hello people! after much joy in the NI forum, i dare enter the LAVA one. Since my first exposure to LV in 1997, i fell totally in love with it. during my scientific period i had used LV extensively, but only within the immediates demands of the goal to be achieved. However, only now i decided to make a life of it, and i discover that there is so much more !! learning now OO, i think i got the hang of it when my wife became pregnant for the second time: you create objects who inherit both parents class, yet have better functionnality! with much expectations
