  1. I have gotten a VM working in virtualbox using the PC utility from MAX. My issue is that I really want to be running NI-Linux Real-Time (Intel x64-based) and not pharlap. If I read this right, That is for a real time cdaq chassis. I am developing software remotely from the hardware and would like to do some things and test within the linux environment connected to my pc.
  2. Seeing what changed with the Lava forums. Been a while

  3. QUOTE(Neville D @ Aug 23 2007, 06:36 PM) my architecture allows for logging. But the listbox control is interesting... could setup an input on the initiialize of my queue to open a clone front panel, and then use that listbox idea to display a state history, so to speak. hmmm, interesting idea. It might get a bit complicated since the manager can handle multiple queues running at once... but a debugging tool to look into non, the less. Might be nice to use a multi-column list box, with iteration next to it... so that the number of duplicated states are not adding to the list. In that I
  4. QUOTE(Ben @ Aug 23 2007, 07:53 AM) Not wanting to take the credit, it was suggested up higher. If you click on the link to my samples, there is a template ready to download that provides a base framework. Amazingly similiar to others I have seen. I guess when you are on the right track, you start to see convergence on simularities. It implements all that I have suggested above, And can very easily be modified to a two loop machine. The one feature I have not seen in similiar architectures is using a multiline string to add states rather than the pesky array constant. For me, it makes
  5. This reminds me of a conversation that went on some years ago petitioning NI to remove sequence structures from LabVIEW as well as another that wanted global variables removed. The core of both arguments was actually due to poor user implementation, and NOT the actual tool itself. This framework, like any other tool works just fine if the programmer has discipline. naming states with some sort of grouping method, logical dividers, a state, for debugging, that catches undesired cases, a cluster that is passed thru so that adding/deleting variables that need to be accessed in every state is o
  6. oh no, I was not taking this personally.. LOL. Just stating that I was not utilizing a generic interface. actually the opposite, I expect the parent class to access the data of the child class.

  8. These are not your garden variety decoders. These are professional grade decoders in use at the head ends of TV station transmitters. So no, not a generic decoder. However, one system can handle up to 16 decoders.. that may or may not share the same settings. Does that make sense? There are other classes that I will implement such as a files class... but if I can grasp this interlink... then the rest will come easier. I guess since LabVIEW OOP does not implement properties... such as a .dot interface. It does make it more difficult.
  9. QUOTE(Tomi Maila @ Aug 20 2007, 01:22 PM) I understand how to do what you are saying, it seems that it is a workaround. I might have performed the inheritance wrongly. decoder != "is a" setting. Rather, decoder "Has a" setting. Thus my desire to 'attach' hSettings to hDecoder. I am not trying to argue, rather I am trying to understand. The end user has reasons to change settings for those instances and , may change them on the fly. Thus a class all to themselves with plenty (about 200) properties (you would be amazed at how many settings an mpeg decoder can have.) However hDecoder
  10. At the behest of Tomi... I am posting here. I have been doing a lot of reading here, the NI forums, and expressionflow.com. Frankly a lot of the theory goes over my head, so I can take it on faith for now. It seems that most articles are really to show you the benefits, but not how base implementation of how OOP in LabVIEW is done. Or I am just to entrenched in data flow... and am having trouble getting my mind around this. Either way.. I want to do this right, and not just work around it. When I envision OOP, I see an object (class) with actions (methods) and adjectives (propertie
  11. repeatively writing to TDM files causes memory leaks. I do not know if this belongs here. NI is aware and it is corrected in LV8.
  12. Funny, you can not access the SCC functionality from the custom menu dialog. Have to open your SCC tool to take action. Should be an easy fix for a future version!
  13. The only issue here is that they have to be different for every divider. Not a major big deal, but there non the less, plus tunnels need to be addressed. I frequently turn off the default if unwired to keep me from making an oops. With various state machine architectures, this should be a feature available in the state case similar to the custom menu dividers.
  14. Bookmarks or Hot spots in diagrams. Frequently queued message architecture has lots and lots of states (see my next wish). I would love to be able to set a bookmark, hotspot, hyperlink and have a floating palette that allows me to one touch navigate centered on that section. Please do not forget the back! Yes, I know I can set a discrete text tag down and use the find, but that is a crippled work around at best and I get no back.

    Wire Labels

    My only issue with Wire labels would be, that it would place the labels in the worst place possible, the way auto-wire routing works. If they do it, you should be able to slide the label along the wire! Additionally, you should be able to click on a wire and have it inherit the label from the previous junction. If you put a wire description in outside of any structure, the wire on the inside of the structure does not maintain the description. FINE, but allow me to right click on the wire and inherit the description. That would be my implementation. Plus color coordinate the label to ma
