subtract the error function

Maybe it's a mistake on my part of basic mathematics, but I'm sure 9 less 2 is 7 and not-2.

Seriously, someone has come across an instance where the function of subtraction mess up like this (see screenshot)?  I tried to replace the function of subtract several times, and it is impossible that the values are simply by changing so fast that I do not see the true values being passed to the function, because the values are the values of thread retention after that I stopped the program.  If I leave a white VI and just put in the 9-2 it outputs 7, as they are supposed to, is not a problem with the machine.

I found ways around this problem of course.  For example, if I replace the subtraction function with a composed arithmetic add function and put in a - 2 for the constant it works correctly.  (Note: replace the simple add function and using a constant - 2 does not .)  Also, if I convert the value of the variable (represented by #38 probe in the image) to a double representation, instead of the I32 either, that works too.

In any case, I'm just curious as to if I am the only one affected by this bug, or maybe someone knows why this bug occurs?

It is possible that you have found a bug in the behavior of the system of values keep.  Since LV 2010 had some changes in the way the code is compiled, it is possible that it was introduced it there.  If you have the means, try to run your VI in 2009 of LV and see if it has the same behavior with the values to keep power on and off.

If a person of NEITHER sees what wire and jump in, they can request a copy of your code that you could send their private for them to try and understand what is happening.

  • I don't know why I get the error "function object is not defined" with this script.

    Hello

    I have a script which adds a unique model in the render queue and applying a Render parameter model and model output for adding module make element of queue.  For some reason, I am getting an error on the first line which reads:

    app.project.renderQueue.items (1), .applyTemplate ('MY SETTINGS');

    I have attached the image of here error dialog:

    Screen shot 2011-07-28 at 12.28.32 PM.png

    Here is a part of the script.

            var currentProjectItem;
            var globalCompItemID;
            var renderCompItemID;
    
            for (var i=1;  i <= app.project.numItems; i++)
            {
                currentProjectItem = app.project.item(i);

                }
            }
    
            //add the necessary preview render jobs
            app.project.renderQueue.items.add(app.project.item(renderCompItemID));

            app.project.renderQueue.items(1).outputModules[1].applyTemplate("MY SETTINGS");
            app.project.renderQueue.items.add(app.project.item(renderCompItemID));
            app.project.renderQueue.items(2).applyTemplate("MY SETTINGS");
            app.project.renderQueue.items(2).outputModules[1].applyTemplate("MY SETTINGS");
            app.project.renderQueue.items.add(app.project.item(renderCompItemID));
            app.project.renderQueue.items(3).applyTemplate("MY SETTINGS");
            app.project.renderQueue.items(3).outputModules[1].applyTemplate("MY SETTINGS");
    
     
    

    The model I want to add is added to the render queue, it simply refuses to invoke the method applyTemplate() on the most recently added make queue item.

    Any ideas why I get this error?

    Thank you!

    I think that from the line where the error occurred, you must use renderQueue.item () instead of renderQueue.items () (except when you add something to the rendering queue).

  • Compile the creation of the error function, over and over again

    I don't see anything wrong with this function. Everything I run with SQL Developer I get a compile error, I try to fix that and get five more who have no sense. All "inappropriate" generic syntax errors

    There is something terribly wrong with my function? I have re-written so several times, I think that I did nothing, but tried to slip in with the DB knowing, which is not me to get anywhere.

    Any ideas? At this point, I think Developer SQL (for Mac) is just smoked. I often force quit

    INSERT INTO STAFF VALUES
    (011, 4, '9992223535', 'HR');

    Your function does not much sense in my opinion.

    You have these variables to input emp_ * and staff_ * that you concatenate in an emp_information of VARCHAR2.

    Then you try to SELECT those variables based on the query in the function (which is not allowed by the way) entry.

    You probably want something like this I guess:

    CREATE OR REPLACE FUNCTION emp_status (staff_id IN NUMBER)
    RETURN VARCHAR2
    IS
            emp_information VARCHAR2(80);
    BEGIN
            SELECT employees.e_first || employees.e_last || ' has rank of ' || staff.s_rank
            INTO    emp_information
            FROM    Employees
            ,       Staff
            WHERE   STAFF.S_ID = staff_id
            AND     EMPLOYEES.E_ID = STAFF.E_ID; 
    
            RETURN emp_information;
    END;
    

    Your original code does not include a JOIN with the STAFF table I added.

    However, in reality you do not have a function at all. you could just do the following:

    CREATE VIEW EMP_INFORMATION_VW AS
            SELECT  staff.s_id
            ,       employees.e_first || employees.e_last || ' has rank of ' || staff.s_rank AS     emp_information
            FROM    Employees
            ,       Staff
            WHERE   EMPLOYEES.E_ID = STAFF.S_ID;  
    

    Then, you could do:

    SELECT EMP_INFORMATION FROM EMP_INFORMATION_VW WHERE S_ID = :STAFFID
    

    HTH!

  • Get the error: DROPDOWN list is not a function - works in IE9

    I'm trying to remove the default selected value in a drop-down list.

    The call to the function is the following:
    OnChange = "JavaScript:Remove_Default_Value (this); »

    Here's the function:

    function Remove_Default_Value(DROPDOWN) {
     var i = DROPDOWN.options.length - 1;
     for ( i; i >= 0; i--)
     {
      DROPDOWN(i).defaultSelected = false;
     }
    } 

    The error I get is "drop-DOWN list is not a function".

    Any ideas is greatly appreciated.

    It is not a function, but a table and you also use getElementsByTagName()

    function Remove_Default_Value(DROPDOWN) {
     var i = DROPDOWN.getElementsByTagName("option").length - 1;
     for ( i; i >= 0; i-- )
     {

  • Error when you try to call the Javascript function in the ActiveX Web browser

    I have a requirement to call a Javascript function in a web page that is displayed in the browser's ActiveX control.  I have the control on the front panel, and I use the Navigate method to call to the top of the appropriate page.  Based on an example, I found, I'm trying to get a reference to the HTML Document so that I can then get a reference to the Fenetreparent.  There is a method of the HTML Window object called execScript who I'm calling.  See the attached image of the code (reference close calls do not appear, but when I run it, they are there).

    I can't the node property that returns the parentWindow reference.  The error I get is the following.

    Error-2147467262 LabVIEW: (Hex 0 x 80004002) No. taken such interface supported.

    Any ideas on where to go from here?

    Hello

    I have reproduced the issue and the error you are seen and tried to understand what is the solution.

    It seems that the problem is with getting the pointer to the parentWindow.  From what I read on MSDN, it's maybe a limitation in the use of an ActiveX control in LabVIEW. It seems like Internet Explorer creates the object of the window, and so opening in one ActiveX control you free access to this top-level object.

    Here could be workaround for javascript execution in your program:

    I would like to know if it works for you and if it will work in your program.

  • Why do I get error 200524 for the generating function 2 code example?

    I get the following error message:

    Error-200524 occurred at the generating function 2 channel_lv86.vi

    Possible reasons:

    Scripture cannot be performed because the number of data channels does not match number of channels in the task.

    When writing, provide data for all channels in the task. You can also change the task so that it contains the same number of channels as the written data.

    Number of channels of task: 1
    Number of data channels : 2

    Task name: _unnamedTask

    When I downloaded and ran the 2 channel here code: https://decibel.ni.com/content/docs/DOC-3545

    I have a card pci-e DAQ 6259 and a block BNC-2110

    Why I get this error?

    When I open the VI I selected ' Dev1/ao"under physical channels. I tried all the other options (a0 - a3) which gave the same error message.

    If you have 2 channels in your data (as indicated in the error message), then you must choose 2 channels in your task control (the error message says that you have selected only 1.)

    You saw in the example how they were able to identify the 2 channels of analog output?

  • 'Require the error' try to call reverse geocoding function of geo_search.h


    I am trying to create an additional function in an existing extension using WebWorks 1.0.4.11.

    The function is geo_search_reverse_geocode in geo_search.h

    For now I'm just using the code example in the documentation on this function.

    http://developer.BlackBerry.com/native/reference/core/com.QNX.doc.Geolocation.lib_ref/topic/geo_sear...

    So therefore, my code looks like this.

    /**
     * Test Function to performs a reverse geocode lookup.
     */
    string TExtn::performReverseGeocode(const char* handle) {
    
        string result = "";
    
         geo_search_handle_t handle_t;
         geo_search_error_t error = geo_search_open( &handle_t );
         if ( error == GEO_SEARCH_OK ) {
           geo_search_reply_t reply_t;
    
           // for now, use the location in the example.
           double lat = 39.8017;
           double lon = -89.6436;
    
           error = geo_search_reverse_geocode(&handle_t,
                                              &reply_t,
                                              lat,
                                              lon,
                                              GEO_SEARCH_BOUNDARY_CITY);
           if ( error == GEO_SEARCH_OK ) {
    
                 // do something with the results in the search reply
                 result = decode_reply( &reply_t );
             geo_search_free_reply( &reply_t );
    
           } else {
               result = "unknown";
           }
           geo_search_close( &handle_t );
         }
    
         return result;
    }
    

    Before adding this feature, the extension causes no problems in my webworks app.

    Now that I've added the function call, I get this message that appears when running my application webworks.

     

    Need error cannot find /usr/lib/webplatforms/plugins/jnext/libTJNext.so library cannot be found

     

    * edit: libTJNext.so is the name of the shared object containing my extension.

    I use the same build scripts, and if I comment my changes to my hpp/CPP files, extension begins to work again (but without the support of geocoding).

    I hope that the message itself is a herring-saur, as the so is included in the file of the bar (I checked), so I expect to be installed when I install the application.

    What I am doing wrong?

    Yes, the message is a red herring. As a general rule, if the system cannot load a .so due to a connection problem, it shows the error. Have you noticed on the documentation of the API that it uses this library: libgeo_search?

    This library must be added to your project in order to to use. Without it the binding will fail and you will get this message.

    The process of adding that is documented here: https://github.com/blackberry/WebWorks-Community-APIs/tree/master/BB10-Cordova/Template#including-li...

    This section of the manual applies to extensions times WebWorks 1.0 and 2.0 WebWorks, although a large part of the rest of this file applies only to the WebWorks 2.0.

  • How to deal with the error "failed to get the kernel function pointer".

    I was running smoothly first Pro CC all day today. I stopped at the end of the day and now when I try to launch first yet, only a few hours later, the program will not open and I get the error "unable to get the kernel function pointer.  Help!

    I run first on a Macbook pro i5 processor at 2.3 Ghz with 16 GB RAM, graphic card 512 MB intel HD 3000 running OS 10.10.3.  It worked well (although sometimes a little slowly) for one year. I keep the project file on the portable hard drive, media files on a port firewire 800 Gdrive.  It has been working well.

    The only thing that happened between the first success today and refusal to open the first tonight, I ran something of card/holiday calendar interactive multimedia for my son that I had installed a few days ago but not yet opened. When he installed Abobe AIR opened and did the installation.  To see if this can help, I uninstalled the holiday card and rebooted the computer a couple of times. No dice.

    Help!  Luke

    I have the same problem on several machines. What seems to be the case is first is losing track hence basic audio filters are on the system. The only solution that works for me is uninstalling first, then put it back. I found myself to do this every day or almost.

Impossible to set up a text box. How can I fix it? Thank you

    Suggest that you reset the text tool, that only he can fix.

    I believe in PSEv.11, there is a small arrow, top of the page to the left on the tool options bar. Click on this.

    If the arrow is not there, look in the options bar to the text tool, on the right, for a box with lines inside. Adobe changed the location and icon in later versions of the program.
