Summary of functions (two entries) for classes of brother with a dynamic distribution of entry: the static entry retains the type of the parent class.

Suppose that in a hypothetical example, I have a superclass (number) with two children (real and complex) classes.

I would define a function of sum for these classes, using dynamic distribution.

Real or complex would have its own method of the sum (VI) which would be subject to various operations, such as the real and complex numbers are different.

As I understand it, the normal way to proceed in OOP is for each of these methods to have an entry of dynamic distribution and a static entry of its own type.

Problem: Labview doesn't let me do this!

I first define an input method dynamic-shipping dummy for the numberof the parent class, but only the first entry can be dynamic-Envoy while the other is statically typed as number.

Then, when I create override methods in my two children classes real and complex, the second entry (static) remains under the number (the type of the parent class). This is not fair, because then I can't access the private data of the child class of type real or complex that will be connected to the second input (static).

What is the solution to this problem (usually)?

I think that, in LVOOP, you use only a dynamic terminal or a static terminal to the terminal object.

You can have several other terminals, but all the dynamics VI (methods with the same name) must have the same API (terminals).

If you have to understand your preferred mode to pass, use multiple terminals, not used by each method, or use a cluster that contains all the numbers to pass (real or complex, both of which are not used in each method) or you can try a Variant, as shown.

  • Which is better: Labview for everyone or learning with Labview?

    I am a novice user of Labview, but I went through essentially through the 6 hours on Web site tutorial for NOR and that I'm currently going through the massive list of examples included in Labview. I heard the two Labview for everyone and learning with Labview recommended texts. I'd rather pay one, unless I really should bring both eventually. Thoughts and opinions by comparing the two?

    The two books are very good.  If your just starting, go to Amazon, buy a copy used learning with LabView 8 or 9.  I got mine for $18 shipped.  You can download all the vi.  Can also buy LabView for everyone $61.  LabView for everyone covers almost everything on LabView and brings you to some more advanced things, but learning with LabView has been better for basic stuff.

  • Very weird behavior of LV OOP/classes: wrong dynamic distribution method is called

    I have very strange problem: a Subvi (start_scanning.vi) in my software is supposed to call a method on dynamic distribution (send_trigger.vi) of a class of LV:

    However, instead of calling the send_trigger.vi, a completely different method (with a different name and a component of connector without matching) of a class parent is called. LabVIEW then immediately displays a dialog box indicating "LabVIEW: an input parameter is not valid." For example if the input is a path, the path can contain a character not allowed by the operating system such as? or @. The first level VI "main.vi" was arrested in stranger on the block diagram of the 'GenericPlugin.lvclass:set_current_objective.vi '.

    GenericPlugin.lvclass:set_current_objective.vi (mentioned in the message of the dialog box) is the method that is called instead of the correct method. The input parameter invalid, that the message of the dialog box refers to is probably the enum that I pass to my method of distribution dynamic (this enum of course does not match the input parameter expected by set_current_objective.vi).

    I tried to give LabVIEW an additional clue he's trying to call the wrong way by putting another input to the façade of the set_current_objective.vi control (and plug it into the connector pane). Indeed, this change something: LabVIEW then completely stalls (does not respond to ANY user input more), but the correct method (send_trigger.vi) is not executed (sensors inside the method do not run). What is the case if, rather than add additional control on the front of the set_current_objective.vi Panel, I try to pass another enum value to send_trigger.vi.

    A strange observation is that at some point the VI (e.g., start_scanning.vi) somehow try to call the method of dynamic distribution gets locked (the façade seems that ran the VI; and the block schema cannot be modified more).

    I would be grateful any indication which could help me to solve this problem, because I am really stuck now...

    All of the code-compilation of mass seems to have solved the problem.

  • Minor problem with the New Installation of Windows 7 on my Inspiron E1705/9400 - two entries for "Base system device" under "Other devices" with yellow exclamation point

    Hello

    First of all, let me tell you about my system.   It is of a laptop Inspiron E1705/9400 with the Core 2 Duo T7400 processor clocked at 2.16 GHZ.   It has 2 GB of RAM and a hard drive on the Hitachi Travelstar nine 500 GB (7200 RPM).   It also has the GeForce Go 7900 GS video card.    Previously, it had Windows XP Professional (32 bit) and worked well.   But, I have three computers in my home and Home Office and would they work better together on my wired home network, so I'm upgrading all three to Windows 7.   My two desktops (a Dimension XPS 420 and the other Dimension XPS 430) seem like they will be no problem to upgrade to Windows 7.   But, this laptop was not on the list of Dell Windows 7 compatibility.   However, the Windows 7 Upgrade Advisor that I have downloaded and run seemed to say that it was OK to do a clean install of Windows 7 32-bit and he had only a few minor issues, where it says search the drivers updated from the manufacturer.   Initially, the laptop came with a 100 GB hard drive.   For my use, which becomes very small, so I decided to get the exact same 7200 RPM drive 500 GB size.   This will allow me to do a clean install of the 32 bit Windows 7 OS on the new hard drive and not have to wipe the old disk to do so.   I can just keep the old HD and paste it back whenever I need to get something out of it.

    So, here's my minor problem.   After the transfer of some elements off the coast of the old hard drive, I installed the new 500 GB drive and installed a cleaning of the 32-bit version of Windows 7.    I'm happy to announce that I have not had virtually no problems with installation and everything seems to work fine.   He seems a little more zippy than before and I have not met so far that doesn't seem to work.   I went through most of features and almost everything is superb.   But there is a minor problem, showing in Device Manager.   At least, I think it's a minor problem, but maybe someone can give me feedback to know if she is or not.

    In the Device Manager list, there is a category called "other devices" now and the icon shows a little white circle with an exclamation mark.    When you expand this category, you see two identical entries that say "Base system device" and the icon has a yellow circle with an exclamation mark inside.     I know from experience that it is not a good thing to see items in the device manager that have a yellow circle with an exclamation point.   I clicked on both of them and neither one really tells you what the device is, or who did what is site you would go to a driver.    On the general tab, it has the following information:

    -Device type Other devices

    Reference of the manufacturer- Unknown

                         Location     -         Bus PCI 3, device 1, function 3


    Under device status, it says the following:

                           The drivers for this device are not installed. (Code 28)

    There is no driver selected for the item or a set of device information

    To find a driver for this device, click Update driver.

    Each of the entries seem to be almost the same thing... but not exactly.   The other has the location

    list PCI Bus 3, device 1, function 2... instead of function 1.   This seems to be the only difference.

    I tried the button to update the driver, but that doesn't seem to work.   No matter if you say it looks like your

    computer or to look for a new driver from the internet, it does not find anything.     As I said at the beginning,

    the system seems to work very well... but, given that I don't know what this device is or does, I might be missing something.

    He drives me crazy just have these yellow circles with exclamation point hanging out in my device manager.

    I could really use some help here.    Any ideas or help would be greatly appreciated.

    Thank you

    Bryan Ray (Richmond, WILL)

    BTW, I just downloaded and installed the driver pack from this ftp location and it worked, even for Windows 8.1 - 64 bit.

    Thanks Steve!

  • I use Photos to make a schedule, and when I add national holidays and have a personal calendar already selected for the import, national holidays replace a personal date when the two entries in conflict.  Any suggestions?

    I use Photos to make a schedule, and when I import two calendars of Mac, I can't play well together.  By example, if I add the national holiday calendar to a personal calendar already selected for the import, national holidays replacement a date personal when the two entries in conflict.  Users are allowed to several elements to show on a given date (I can add an article manually; and if I have two elements in a personal calendar, they both matter very well).  Does not seem serious if I import successively or simultaneously, the holidays always seem to prevail on personal items.  I am proud of my country, but want to avoid adding those who back in manually (and avoid having to check everything so closely).

    Any suggestions?  Thank you

    John

    (running Yosemite on a mini 2015)

    There is no way to have both separate schedules added and share a date.  Tell Apple what missing features you want restored or new features added in Photos via https://www.apple.com/feedback/photos.html.

    You could create a new calendar with personal anniversaries and holidays.  I think that would be the case with the exception of those holidays that might change the date to when if fell, which is Memorial Day for one.

  • Cannot use casting "to more specific class ' function to the parent class of child class

    Hello

    I am using OOP for my request for data acquisition. I have different e/s analog and digital materials. I create a superclass named DAQ.lvclass. This class has four childs: analog in out analog, digital, and Digital Out. I am trying to invoke screws of the child of the parent class's class. For that I am throwing the class parent her child to aid "to a more specific class' function. But I get the below error.

    Error 1448 occurred at the more class specific in DAQ.lvclassMain.vi AQ

    Possible reasons:

    LabVIEW: Bad type cast. LabVIEW does not deal with the run-time value of this class of LabVIEW as an instance of the given class of LabVIEW.

    How can I handle these cases where I have to call child VI of the parent member?

    I have attached two screws 1 snapshot. Main DAQ: it's the class main VI parent who manages all functions. 2. read the analog inputs: this VI trying to set the parent class for its class of the child and child vi reads value of data acquisition task. I get the second error off VI.

    Kindly help.

    Honestly, I have NO idea on what you want to do.

    Inheritance of classes in EACH OOD (object-oriented design) requires to define common ground as the parent class. Children can add things like properties and methods.

    If you set children who have no points in common, you have made a mistake.

    If all children have too many different specific methods, your OOD is absent.

    Example:

    Parent defines the method A.

    1 child adds the B method.

    Child 2 adds method C.

    But method B will not be usable on 2 children while method C will not work with 1 child.

    It is an approach that you want to prevent. In any programming language oriented OBJECT. This adds unnecessary complexity leading to difficult to maintain the code, and it is prone to errors.

    However, if you're going to do, "to more specific class ' is the correct type cast. But your screenshots and error messages, it is obvious that refine you a particular child's casting only. You must extend the code to check the real child, specifically expressed and call the method. That being said, your code increases the complexity you want to add a bunch of case of structures which essentially nihilates all THE BENEFITS of the use of OOP.

    I'm sorry to say that.

    Disable any first your region recover flash.

    My Firefox browser page to have a Norton Safe Search Bar within the toolbar area. He must be active on this subject otherwise the function AutoComplete passwords for sites Web I visit - who have need of my username AND password - is not populated automatically by the software Norton Internet Security 2011 that I have on my computer.
    My Question: HOW to make this search bar of Norton on my Firefox browser Page?

    I use Norton 360 institutions and would allow the two Add-ons of Norton (see below) when I upgraded to Firefox 8.0:

    • Norton Toolbar 2011.7.3.6; and
    • Symantec IPS 3.2.

    In your case, since you have used before, add-ons can still be installed, you should just allow them, as if I had to do. 8.0 Firefox automatically disables modules.

    To see if the modules above are still installed, you can:

    • go to \Firefox\Add-ons;
    • Click Extensions;

    .. .and you should find them there. If this isn't the case, you need to install. You can use the links that Daniel and the-edmeister provided above.

  • Why the parent class does not report data for child in LVOOP class?

    Attached is a practical program that I wrote to learn about the legacy with LVOOP.

    I have the impression of OOP is a Parent class describes the type of object.  Then the children inherent description of the parent.  The child may also have additional qualities, but it still contains the description of the parent.  If a child does not have a VI bearing the same name as the parent and the parent VI will be loaded and executed.

    My questions:

    (1) why does the Parent.lvclass:Read.vi not report 'Child' in the channel indicator when the child write VI has been sent?

    2) matches the data of the child, do not at all seen by the parent company even when it has the same definition (that's the String)?  I understand that the Parent do not know anything about the unique child elements, but I think we should know about the common themes which inherited the child.

    Here is my sample code:

    These are two different sets of data. The parent class has a data set containing the string, the class of the child also has a data set containing the string, but both of these channels are separated.

    This can be made apparent, by changing the names of the channels based on their respective categories:

    What you want is for your children, class VI write to access the data of the parent class. You can do this with a simple data VI member access in VI of the child:

The operation could not be performed as indicated "." Can't use two assistants for the acquisition of data at the same time?

    I have to add different channels in the same assistant DAQ? I tried, but I couldn't separate the data in different graphs.

    How does this work?

    You can't have multiple tasks of the same type (in this case inputs analog) on the same device.  Just so having 1 DAQ Assistant read all your channels and separate your channels for individual transformation.

  • XPS 12 + two S2340T for three monitors have contact problems

    I am testing a configuration of business as part of our R & D in the field.  I'm running a Dell XPS 12 8.1 Windows.  Last week, I ordered two external monitors S2340T for use with my setup.  In the past, I was able to successfully run the two external monitors for a three monitor Setup.  When I plugged in the first S2340T, everything worked fine. When I connect the other, I lost the ability to screen on the first.  On the second, when I touched the screen, he was interacting as if I touch the screen of the PC clean, despite the fact that he was it running correctly as extended desktop. I finally found that each monitor must be running with the USB cable (I found this in a forum of the year, even if the instructions I received still makes no mention of the need.) At the moment I touch on the screen of Mobile PC, as well as the first S2340T (monitor 1) that I am connected.  The other I'm connected (screen 2) takes any action contact and is the space in the mobile PC display.  If I disconnect 1 monitor, monitor 2 will work perfectly, as expected.  If I plug then 1 monitor, it won't work properly, allowing a contact immediately to show as a touch control on the laptop PC screen (thus imitating the question I had when monitors were reversed). I completely replaced the Dell drivers, even those it says is up-to-date.  I've disabled and upgraded.  At this point, I don't know what to try next.  Dell has recently told me to update my Bluetooth driver for a separate issue and immediately after, I lost the Bluetooth connectivity option and my Bluetooth mouse functionality. After you run an update of the driver from Dell, I lost my Bluetooth receiver on the laptop.  Fortunately, I've seen it before and all I have to do is to re - install the VPN we use SonicWall Global VPN client software.  Restart the system and my Bluetooth is back; but now neither monitor reacts to the touch on the scree, each monitor shows the point of contact as being on my Dell XPS 12.

    Try this...

    * Unplug the two computer screens
    * Reconnect the two monitors by USB 3.0 only (do not use DP or HDMI)
    * Use Windows to configure the monitors in extended mode and save this configuration
    * Go to the control panel
    * Contact search
    * Tablet select configuration - installation
    * You will see a screen that says "Touch this screen to identify it as the touch screen if it is not the press serigraphy tablet PC enter to move to the next screen.
    * At this point, press enter
    * This message will move to one of the external screens
    * Press the screen near the message until the message "press on enter to move to the next step in your configuration to compete."
    * Press enter
    * At this point, if only using a screen external, you will be on the tablet settings screen and you can close it. If you use several external displays, the original message will be then posted on other external display
    * You will see a display on the other monitor that says "Touch this screen to identify it as the touch screen if it is not the press serigraphy tablet PC enter to move to the next screen.
    * At this point, press enter
    * This message will move to one of the external screens
    * Press the screen near the message until the message "press on enter to move to the next step in your configuration to compete."
    * Close this window
    * Now every touch screen will work independently without affecting the other or the laptop screen
