  2. GOOP Developer free of charge for commercial use

    in Announcements

    Posted

    I suppose my main reason for doing this is that I get a real kick out of having my software used.

    Making money out of GOOP developer was never my primary motivation for creating it, it grew out of an interest of mine and then into a passion/obsession, I had tremendous fun developing it and it’s a tool I cant live without and I love it when other developers are using it to build their systems. It’s paid for my LabVIEW licenses over the years and put some change into the beer fund, but the market that this tool appeals too though is quite small, smaller still is the group within that market who can afford the tool or get approval to buy it.

    About 18 months ago I released GOOP Developer free of charge for academic use because there were people out there who wanted to use it for academic purposes but couldn’t afford or get approval for it, so I thought it would be cool to help them out.

    Another reason is that GOOP Developer has marketing value, it gets people visiting my site which is important now that I’m working towards becoming an alliance member and concentrating on my development services.

    Hi SciWare

    What is the difference between LVOOP and GOOP Developer ?

  3. RS232 to USB converter

    in Hardware

    Posted · Edited by Bjarne Joergensen

    Hi All

    Thanks for the replyessmile.gif

    I admit that the question was a quick one that I got to answer friday afternoon, before I went on hollyday.

    So I didn't have so much time to find a lot of solutions.

    Hmm... lots of USB port -to- DB9 device converters out there, not so many DB9 port - to - USB device converters.

    Do you have room in your PC for a USB card (PCI)? You can get one of those for under $20.

    About the PCI solutions. Yes there are room for that but I don't know if Modula can talk with USB?

    Maybe it can if the USB device act like a serial device. Then I only need drivers for Win98.

    I really don't they such a device exists. (I could be wrong)

    As already suggested you could add a USB PCI card.

    One other option might be ethernet to usb.

    However, this sounds to me like an excuse to upgrade the PC! smile.gif

    Yes, it is a excuse for not upgrating the PC!. We got at test runing now with some other products and we will not upgrade them to a newer platform(product-lifetime i limited).

    If you can't afford the equipment needed to test a device you're manufacturing then I would re-evaluate your business plan...

    Yes Michael, maybe we should do that, but that is not my decision. By the way as I mentioned, we shall produce max. 200 pr. year(maybe only the first 3 years, then the number will drop) with a costprice of 40$. A new PC (I can only use standard PC's that our IT department has aproved) and development/inplementation cost will be around 3800$(danish prices) resulting in extra 18$ pr. unit the first year!

    There are a lot of other questions to handle according to the production setup.

    I will be back with the solutions after my hollyday.

    Regards Bjarne

  4. RS232 to USB converter

    in Hardware

    Posted

    Hi

    I am looking for a RS232 to USB converter and can't find one.

    It's not for Labviewoops.gif but and old PC with Win98 and Modula2 SWoops.gifoops.gif .

    I have to test a new little divice that we produce. The old device are with RS232 connection and the new device with USB.

    If I could get a converter to plug in the old PC's serial port and put the USB device in the converter, it would be the cheapest way.

    We only produce 200 pr. year of the new device (price pr. unit 40$) so it's to expencive to by a new PC for the purpose.

    hope anyone can help me.wub.gif

  6. FP resize and change position when VI stop.

    in User Interface

    Posted

    Hi

    This is strange (for me :wacko: ).

    Try open these 2 VIs and run the "TestVIStart.VI". Then TestSub.VI start.

    Download File:post-7489-1236342950.viDownload File:post-7489-1236342962.vi

    When the Boolean stop blinking, then you shall top the TestVIStart.vi by the Stop button. Now watch the size of the FP on TestSub.vi.

    Start the first VI again and see the FP size is growing bigger on the TestSub.vi, when you stop the TestVIStart.vi. :headbang:

    Watch also that the FP has change it's position in run mode. :ninja:

    I have set the VI properties this way on the TestSub.vi:

    post-7489-1236343170.png?width=400

    If I change the window appearance to Default, then it won't happen. :lightbulb:

    Is there a good explanation for that behaviour?

    Use LV8.2.1

  8. MassCompile and _DIR

    in Development Environment (IDE)

    Posted

    QUOTE (crelf @ Mar 3 2009, 09:42 PM)

    Putting a _ at the start of an item in those folders means that LabVIEW will skip them when it's populating it's menus (and palettes?), not when it's mass compiling.

    Then there is a fail in the "Wiki, Use svn directories".

    It says: Use "_svn" directories instead of ".svn" directories so that the LabVIEW mass compiler doesn't try to compile these directories. Right?

    Yes, I have seen the "Rigtht?" but no one has argued against it, so I assumed that it was a fact. :rolleyes:

    But back to the problem then. How can I avoid LV to Mass compile .svn directories. Is there a way?

    Best regards Bjarne

    There is a VI Analyzer test you can use to analyze VIs on disk to see if they call a given subVI:

    http://forums.ni.com/ni/board/message?boar...ssage.id=365628

    This can search inside .llb files. I don't know what version of LV the earliest VI Analyzer was available.

    Hi Aristos

    It works just fine and then I can do the search from the LV environment, instead of using other programs.

  11. MouseUp Event on vertical scroolbar seems not to work.

    Hi

    It seems that the MouseUp event don't work on the vertical scrollbar in a string indicator.

    I have made the attaced VI (LV8.2.1)

    If you try to click at the scrollbar and hold the mousebutton down the VI stop scrolling, butit don't start again when you loose the button.

    I you do the same in the text, it works.

    It's the same in LV8.6.1

    /Bjarne

    Hi

    Is there someone that would be kind to take a look at this and tell me if I'm right or missed something in the LV documentation :book:

    best regards

    It won't work in LabVIEW 8.6 AFAIK. They compress most of the information in a VI file. Freee text labels on the front panel for instance can not be found anymore in this way.

    Hej Rolf

    It works for me, execpt when the files that use the file I'm looking for is in a llb!

    Bjarne,

    My best used tool is the "Total Commander" by Christian Ghisler ( a must have for anyone who once used the Norton Commander). The built in search command works just fine.

    I don't know about other browsers.

    hope this helps

    Hi Anke

    I works just great :worship:

    Now I can find those VIs I have used a buggy lowlevel VI.

  16. Is there a bug in the internet toolkit?

    .

    The format of a response to a PWD command should be:

    257 "fs" is CWD

    If the server is returning the string you indicated, then the bug is in the server
    :o

    Hi Philip

    Thank you. :thumbup:

    I think you are right about that the bug must be in the server. It is a product of our own.

    I will ask the R&D if they are diviating (they must be) from the RFC 959.

  19. Is there a bug in the internet toolkit?

    in LabVIEW Bugs

    Posted

    HI

    I am using LV8.2.1 and the internet toolkit.

    There is a FTP function called "PWD"(print working directory) who I think got a bug.

    It don't put out the working direktory.

    It take the reply text ( ex: Current working directory is "fs" and use the subVI "unescabe double quotes.vi" to remove the quotes, but this subVI need to have a string where the hole text is surrounded with double qoutes.

    The FTP "PWD" function send a string like this( ex: Current working directory is "fs" to the subVI and that result in an empty string out.

    Take a look at the attached pictures.

    It's the same in LV8.6.1

    regards Bjarne

    PS: I have also posted this in the NI forum, but no one reply, so I try here at LAVA :)

  21. Selective array building at structure tunnels

    QUOTE (Michael_Aivaliotis @ May 5 2008, 09:02 AM)

    I like this idea. Along the same lines (or maybe this is hijacking), why does a 1D array always become a 2D on for loop borders? Why can't we concatenate a 1D array at the border. It seems that tunnel has the potential to do a lot more than it can right now in regards to array manipulation.

    I can't se the picture of what you are talking about. What is wrong ?

    QUOTE(Aitor Solar @ Oct 24 2007, 11:47 AM)

    I have tryed with integers and then there is no problem.

    If I set the procision to 20 digits for a DBL-control I see a strange behaviour.

    If I type 0.5 then i display 0.50000000000000000000, but if I type 0.2 then it display 0.20000000000000001100

    Why is that ?

    Update: I found this on Lava http://wiki.lavag.org/Numeric

    This explain the problem

  25. Greater? funktion. Is it a bug ?

    in LabVIEW General

    Posted

    Hi

    I got a problem with the compare function "Greater?".

    I use it the way you can see in the VI.

    With the controls set as default there is no problem.

    The current value cycles between 8 and 4 with 0.2 steps.

    The problem is that when I set the Start value less than 7.6, current value never reach 8.00.

    I can't what's wrong with my VI, or is it the Greater? funktion that got a bug ?

    best regards

    Bjarne Jørgensen

    PS: It's the same behaviour in LV6.1 and 8.2

    The Vi is in 8.2
