  1. QUOTE(Tomi Maila @ Jun 7 2007, 10:28 AM) Haven't mentioned, but 2nd template starts also as a frontpanel. But either way, please explain me why does it work once and once not? And with the traditional (set control value-) node it works all time. Myself I used this node quite often in my 10 LV-years and hadn't one time problem with it. QUOTE(SciWare @ Jun 8 2007, 01:44 AM) It sounds like an interesting application as well. It is, it's a test-framework. The main.vi is an overview of the test rigs in his lab. Since the ammount of test rigs vary over time, their overview are impleme
  2. Hi there, Long time I didn't post something... ...well, a friend of me showed me recently an odd behaviour in a program he wrote in LV7.1.1. The architecture is: main.vi calls a template (with vi-server) and embeds it as a subpanel. From this subpanel and also from main.vi a 2nd template is called with vi-server. The reference of a sciware-goop object is given to this 2nd sub-vi with the node "set control value (variant)"... seems complicated but there is the clue. In the development environment everything works like a charm. But from the moment a built app is done, the "set control valu
  3. QUOTE(TiT @ Mar 8 2007, 01:58 PM) In this sentense there are 2 point in favour of Labview: 1. the New Beetle is affordable by the masses 2. I doubt that one could drive the ferrarri with less gaz as the beetle.

  7. QUOTE(tcplomp @ Mar 7 2007, 01:51 PM) In Switzerland the only (main) contractors are Alcatel (since January 1st named Thales) and Siemens. Actually the swiss federal Rail accept only one axle counter system for new projects and it is the one from Alcatel. So guess in which company I work . QUOTE(tcplomp @ Mar 7 2007, 01:51 PM) And yes you can do LabVIEW at 300 km/h in a high-speed train or a 120 km/h normal train. But not in a 40year old suburb train at 80km/h (which seems to be more than this train was designed for).
  8. Hi LabVIEW'er, Some might have remarked that I was quiet for the last few months... Well, this is because I rarely use LabVIEW since last October. I changed the job! Working till then as a developer, now I act as a project manager (yes, these "useless" ones you could easily put in the same bin as the directors, always behind a word document and doing weired stuff on ms project ) Just to specify: I don't have to wear all day long a tie :!: I work for a company that builds those complicated systems behind the rail signals, to avoid that 2 trains crash into each other.

  9. I tried the trick with "Tools -> Update Virtuals" with the result that now ALL virtual methods return Error 1031 EDIT: Just found the problem: on the parent class I modified the error in to "recomended", but not on the child class .
  10. I have to disagree with you. OO programming IS A METHOD TO SOLVE A PROBLEM (in the meaning of SW-design)!
  11. In the Main menu go to Help>Find Examples... It's full of codes that you can use/modify/combinde to your needs and they are usable (not like some MS-helps )
  12. I have no problems opening and running them. Try to redownload them.
  13. Although I rarely use the autotool (old habits ), somehow I knew that there is a key to "disable" it. Unfortunately I never remember which key it is (have to try it everytime), nor from where I got this info... maybe from a former presentation at a NI-day or VIP-day.
  14. A dumb question, but to me it sounds that you have changed the baudrate on your computer, but have you done it also on the oscilloscope?
  15. Well, this reminds me my last trip to California. One evening I was sitting in a bar in Frisco, at some time a guy asked me from where I was, since my pronunciation was a bit "strange". I replied that I was from Switzerland. The guy had to think a while and after that he asked if that place near SF or LA, since he didn't know it... ...There must also be a few of these people in Hollywood who don't know that there is an outer world (outside US). ps: where is that picture from CNN explaining "war in Europe" (and meaning the war in Jugoslavia). On this picture Switzerland is referenced somewhe
  16. C'mon, Everyone knows that FBI and CIA work hand in hand on a global stage...
  17. There was a poll here. For my part I started with original GOOP (that one from the NI-forum with the password protected vi's :thumbdown: ), moved to openGOOP and now evaluating Goop Developer 2.0 and LabVOOP. Which version you want to use, depends on your needs. "Real" OO implementations (with inheritance,...) are Endevo GOOP, Goop developer 2.0, and LabVOOP: Endevo GOOP has an impressive graphical Project tool, LabVOOP is native LabView. The other ones are older and do just implement static classes.
  18. Depends on the manufacturer... ...Try to find it here
  19. It's more or less what I did, except that I manually click-and-draged each virtual methods conpane to its vi-ref "This VI's Type". But somehow it didn't worked... or should I have dragged highest level conpane to all its children methods "This VI's Type"?
  20. Dear Kurt, I write this request on LAVA instead of Sciware-forum, since it will reach a bigger audience and I hope to see more opinions (from other people who tried it). While using Goop Developer and building a project, it happens "often" (I know it shouldn't ) that a virtual method needs additions on the conn-pane after having created the child-class methods. To my experience this is a crutial step that easily results in a runtime-error "1031, VI Reference type does not match VI connector pane", which is a "pain in the a...<cough>" to resolve ...must have done something wrong, I had
  21. For what does anybody need to have the Class object as a control, except to pass the class to a sub-vi? If one can paste a control for initialization purpose, we are back these ugly "c programs witten with LV". Replace the Class object constant with a customizable "constructor-vi" and you are done.
  22. I agree that if initialisation is needed depends on the concept. In LV (and where it doesn't go to the outside world) there is no initialisation method of any datatype. But from the moment the outer world is concerned also NI always uses sort of initialisation/clean-up (see file, daq, visa, ...). OO programming is not only a way to put fancy boxes around parameters and methods, but a concept where one tries to encapsulate everything that belongs to an object. Inheritance in OO programming is a way to generalize the access to an object, just like IVI. You define a standardized interface for e
  23. ...a new experience to create your easter eggs (not these)... :thumbup:
  24. Wow, nice work you have done. I like your ideas. I haven't made my oppinion on which OO method suits my needs better: LabVOOP or the various GOOP's. There is one thing that bugged me since the first 10 minutes I glanced into LabVOOP: how do one access object data in parallel loops? So far I have on suggestion on your proposal: On page 21 (constructor block diagram) you define a class constant and then you invoke explicitly the constructor of the parent class. But you could also replace the class constant with the parent constructor. In all my implementations I did in Delphi the first comman
