The order of the enumeration returned by NISysCfgFindHardware()?

Hello world

Does anyone know if there is a particular to the devices list order returned by NISysCfgFindHardware()?  I use a PXI chassis with a bunch of cards, so I wonder if it is ordered by the number of accommodation or anything else, or maybe it's just random.  I don't have the material available right now, so I can't test it on mine thank you!

I have attached a piece of code that I used to test this query.

When I ran it I've always seen the controller at index 0 and the chassis at index 1. After that, generally the modules have been listed in the expected order, usually with 'white' in the indices corresponding to the empty slots. I saw interesting behavior after listing modules; for example, in a situation the chassis was registered again directly after the modules without empty spaces of the sale. My best advice would be to be safe and check each resource is what you expect before using it - but it doesn't seem to be a few inconsistencies that you could possibly take advantage of. Please feel free to use this code to test it yourself, but remember that this code has not been fully tested and cannot be guaranteed in all situations.

  • CFFILE READ xml file removes the carriage returns

    When I use CFFILE to READ a XML file (in order to get to the XMLPARSE step), it deletes all the outside between the carriage returns.

    My simple order of action CFFILE = 'read' file variable = "" #tempFile # "="XMLData"results, of course, in the XMLDATA variable." When I've got CFOUTPUT this value, all the transport returns have disappeared.

    In the original raw XML file, there is a section as such:

    < inspection_comment comment_type = '0' > missing tag.

    Channelled to the rear. d < / inspection_comment >

    In other words, there are in fact two combinations of chr (13) chr (10).  Yet, after the CFFILE READING, I find myself with

    Missing tag. Channelled to the rear. (d)

    and no carriage returns whatsoever.   It is a natural phenomenon, because it is an XML file, or I just don't hold my tongue right?

  • Camera IP IMAQdx: Error 0xBFF69035 that the camera returned an unknown HTTP error

    Hello

    Thanks to the detailed advice to http://forums.ni.com/t5/Machine-Vision/Do-IMAQdx-and-NI-hardware-support-GigE-Vision-2-0/m-p/3164373... we decided to move from GigE cameras (Basler BIP2-1920-30 c) IP cameras to reduce CPU load.

    Unfortunately, I cannot acquire images from the camera via IMAQdx. When I click on "Snap" NI Max, I get "error 0xBFF69035 the camera returned an unknown HTTP error. This could be the cause? (The only other thread, that I found is http://forums.ni.com/t5/LabVIEW/camera-return-to-unknown-HTTP-error-in-Ni-Max-during-the-IP-axis/td-... but the steps proposed refers to GigE documentation that is not relevant)

    Notes:

    • The camera is connected directly on the LAN 2 port in the SMU (SMU-8135) controller.

    • I can ping the camera.

    • I can see the video stream from the camera via its web interface (using Internet Explorer to access http://169.254.75.137/webapp ).

    • OR MAX detects the camera, but he doesn't seem to let me set up properly. If I enter any number in the 'width' or 'Height', she gets has forced 1 - this behavior seems fishy.

    Thanks in advance!

    Hi BlueCheese,

    Thanks for your suggestions. It turns out that the IP settings are fine (although I still like to set static IP addresses for the camera and the PXI controller before you deploy the system).

    I found the system log unit of the Basler, who gets a new entry whenever I try to start an acquisition of NI MAX: user.err mjpeg: {2714} HTTP error 503: selected stream has wrong type of video (1! = 5). Then I discovered that (i) the camera default H.264 and (ii) IMAQdx only supports MJPEG, H.264 not.

    Setting the unit to use JPEG compression solves the problem.

    What are the causes of the log of user account on missing cursor in Windows XP? I have two trays of office that they have this same problem. If you restart them the cursor returns?

    Hi DaddyJeff,

    1. don't you make changes before the show?
    2. are you referring to the cursor in the area of user password on the login screen of Windows?
    3. when the cursor goes missing, the mouse pointer works on screen?

    It is difficult to say what is causing this problem. If the mouse pointer freezes or stops working, then we recommend you to reinstall the mouse. To do this, try the following steps:
    a. sign in to Windows.
    b. Click Start, click Run, type devmgmt.msc, and then click ok.
    c. in the list of objects, expand mice and other pointing devices.
    d. right click on the sub element and click on uninstall.
    e. unplug the mouse and plug it back.
    f. the Device Manager, select an item in the list, click the Action menu, click scan for hardware changes.
    g. check if the mouse is detected, if so, then install it.

    See mouse USB which is connected to a USB 2.0 hub is not detected by Windows XP

    if the problem persists, restore the computer to an earlier time. See How to restore Windows XP to a previous state

  • Get the same return of the browser at the request

    Hi, I'm using

    BrowserSession.showBrowser)

    to access a browser of my application (I wanted to integrate the browser in my app, but since I am compiling for pre 5.0 devices, I can't use the new browser.field2, but only the browser.field not so very awesome API).

    It is - I want to make something once the user returns to the application from the browser. Is it possible to somehow get this event? (Once the user presses the back key, it returns to my request from the browser).

    I want to differentiate this event of any other event of first plan-background.

    Thank you

    Dan

    Here's a way to do it:

    1. In your subclass UiApplication, declare an executable field (let's call it "pending").
    2. Just before calling BrowserSession.showBrowser (), the value until an executable you want to run on back.
    3. Back in your subclass UiApplication, override the activate():

      public void activate() {    if (pending != null) {        invokeLater(pending);        pending = null;    }}
      

      With the help of invokeLater is not really necessary because activate() is called on the event thread. However, I would suggest using it when even just to be sure that the executable is run after all the other events that may be pending.

    What I need is:

    If the query above returns at least one record, it should display the line ' Yes. We have one or more employees who worked overtime in November2014'

    before the documents are printed

    Thus, the expected production is

    Yes. We have one or more employees who worked overtime at the November2014

    EMPNAME MONTHS SALARY OVER_TIME

    ------------------------- ---------- -------------------- ----------

    Lothar G.f. says:

    In fact, sql * more is no good tool for use considered.

    Really?  It may be a good reporting tool if you learn to use it as such...

    for example

    SQL > ttitle left 'Yes. We have one or more employees who worked overtime in November2014.
    SQL > select * from emp where empno = 1234;

    no selected line

    SQL > select * from emp where empno = 7788;

    Yes. We have one or more employees who worked overtime at the November2014
    EMPNO, ENAME, JOB HIREDATE DEPTNO COMM SAL MGR
    ---------- ---------- --------- ---------- -------------------- ---------- ---------- ----------
    7788, SCOTT, ANALYST, 7566 19 APRIL 1987 00:00:00 3000 20

    This is just a basic example.  It is possible to get SQL * more to ask for the required criteria and that the title could adjust according to this criterion, as well as the query building on it also.

    However, the OP did not specify SQL * as the reporting tool, so there is little interest providing a complete solution which, until they specify what user interface that they are actually using.

    Hi all, this is my first post here. Very happy to be here.

I did it with as2 and never solved the problem which I am sure is easy enough to solve. I remember someone saying something about levels.

Say that the objects are in a room where the user must visit several times in the interaction. There must be a certain number of objects in the room and drag them into a box to get a done message, I want the user to be able to move to another part of my interaction and come back and be able to complete the conclusion and place the objects in the box without reset everything to where they were first encountered user them.

    All advice, tips are greatly appreciated.

    Looks like you need to add programming that 1) stores the x / y locations of the objects since they change 2) uses this information in position to position objects whenever you enter the picture that they are in.

    You should be able to create variables to store the information that is on a layer that extends from the complete timeline so that the data is stored as it is updated and you move along the timeline.  When you move the object update you its position data. Then, in the context where you have objects use you a simple coding to place objects using this position info... something as simple as...

    Object1.x = object1X;

    Object1.y = object1Y;

    If you are still using AS1/2 you would use _x and FLF instead of x and y
