Extending from QObject results in reference not set error vtable

I have an existing type bean class with QString members bool and a QStringList.

I want to access its properties of QML I want to use QObject.

The class compiles very well without the extension of QObject, but when I add it I get "undefined reference to 'vtable for X.

If this class is compiled:

/*
 * X.hpp
 *
 *  Created on: 08.11.2012
 *      Author: sha
 */

#ifndef X_HPP_
#define X_HPP_

#include 
#include 

class X {
private:
    QString name;
public:
    X();
    QString getName() const;
    void setName(QString name);
};

#endif /* X_HPP_ */

And it does not work:

/*
 * X.hpp
 *
 *  Created on: 08.11.2012
 *      Author: sha
 */

#ifndef X_HPP_
#define X_HPP_

#include 
#include 

class X: public QObject {
Q_OBJECT

private:
    QString name;
public:
    X();
    QString getName() const;
    void setName(QString name);
};

#endif /* X_HPP_ */

No idea why?

I build for BB10 using NDK 10.0.9.386 and I found moc.exe in C:\bbndk\host_10_0_9_52\win32\x86\usr\bin

I executed as described in the linked thread, it created a moc_x.cpp and it compiles now.

However, it seems that for this problem he had incorrect header members in the pro file.
For some reason any this has not changed Momentics in any way, until I added QObject in one of the files.

    Help, please

    Hello

    We have compiled ogg/vorbis standard distribution without any problem. From the looks of your error, looks like you can not be linking libogg. Ensure that you link the libvorbis and libogg. If you are already linking both a also ensure that the binding order is correct. You must link vorbis Ogg before to satisfy the arm's length.

    I get error "the server could not process the request. --> The object reference not set to an instance of an object"

    My code base to set up the soap request

    m_soap.setAction(hostServer + "/" + serverAction);
    m_soap.setHost(QUrl(hostServer).host());
    QtSoapMessage request;
    request.setMethod(QtSoapQName(serverAction, hostServer));
    
    request.addMethodArgument(new QtSoapSimpleType(QtSoapQName("AssociateEmail"),QString("[email protected]")));
    request.addMethodArgument(new QtSoapSimpleType(QtSoapQName("ShowName"),QString("print2013")));
    ....
    
    m_soap.submitRequest(request, endPointURI);
    

    I tried to addMethodArgument without the Type of SOAP

    That is to say.  request.addMethodArgument ("myParameter", "", "myValue");

    I tried to use a struct as shown in another post.

    QtSoapStruct* inputValues = new QtSoapStruct(QtSoapQName("Items"));
    request.addMethodArgument(inputValues);
    QtSoapStruct* item = new QtSoapStruct(QtSoapQName("Item"));
    item->insert(new QtSoapSimpleType(QtSoapQName("Name"), "_OS"));
    item->insert(new QtSoapSimpleType(QtSoapQName("Value"), "BB10"));
    inputValues->insert(item);
    

    It seems as if the arguments are not be attached to the request.

    I was getting an error that it lacked the required fields for the stored procedure.  So I adjusted the .net web service to set default values if the values sent via the web service were empty.  This moved me to the common mistake.

    So, apparently, it was matter of double.

    The first problem was in the client code:

    First of all, I needed to make sure that the parameters passed were in the correct order.

    Second, I found that the addMethodArgument was the right way

    request.addMethodArgument( new QtSoapSimpleType(QtSoapQName("AssociateEmail"), query.value(0).toString()));
    

    The second problem was with .net code.  I needed to make sure that the passed value is not zero.

    if (AssociateEmail == null || AssociateEmail == String.Empty || AssociateEmail.Trim().Length == 0)
                     { cmd.Parameters.Add(new SqlParameter("@IN_AssociateEmail", "No Associate Email")); }
                     else { cmd.Parameters.Add(new SqlParameter("@IN_AssociateEmail", AssociateEmail)); }
    

    And I had to make sure I have done this for each parameter.  Apparently, I sent a couple of empty values, and this caused the shot to the top.

    However, the return value is not always in the best format, but that's another thread.

  • Several return orders exception 'object reference not set to an instance of an object.

  • Object reference not set to an instance of an object on Win 7 IE8

    I get the error message "Object Reference not set to an instance of an object" when looking at VCM / SCM 5.2.1 glancing all summary views as OS / "Machines" or whatever it is in compliance. Usually I see it on a poor observance of run that contains no data.  The full grid view works OK.  The equalizer of graph search progress bar flashes then the view is cleared and just object reference bad.  Reports SSRS based including those with graphics seems OK as a summary of the data on disk but the same in the interface user Web, disk space / readers get the error message.

    This happens on IE8 and Win7.  I used IE8 on XP and it worked OK.

    Have you checked to make sure that your Pop Up Blocker is turned off?

    How do you access the VCM Console?  By its IP address?  Host name?  FULL DOMAIN NAME?

    I have just rant in a problem where PUB was causing havoc on some, not all, summaries node.  I would check there first.

    SRS is capricious, when it comes to access the VCM Console, if you want to ensure your are accessing your Bowser with the same naming convention that you used during the installation of VCM.

  • Error "Object reference not set to an instance of an object" when you try to use a disk with vSphere Client

    Hi all

    I searched exhaustively positions but found no answear that.

    I'm trying to access a virtual disk that is free (no machine not in use now).

    For this purpose, I am went to a virtual computer, then clicked on edit settings - & gt; Add hard drive - & gt; use a disc

    Then, when I am prompted for the disk, I select it and click ok.

    When I click on 'Next', you will receive the following message:

    Object reference not set to an instance of an object

    (it seems really in Spanish: Referencia an object no set como UN instance object)

    And then the next button appears as non-cliquable.

    Any suggestions?

    It could be related to the .NET Framework, so I write here the versions I have currently installed:

    .NET framework 2.0 SP1 LanguagePack

    .NET framework 2.0 SP2

    .NET framework 3.0 SP1 language pack

    .NET framework 3.0 SP2

    .NET framework 3.5 SP1

    All this with the patches.

    Thank you in advance for your help!

    PS: I found there was information about the lost pilots and VSphere Client. I already changed those:

    %RootDrive%\%ProgramFiles%\VMware\Infrastructure\Virtual infrastructure Client\Launcher

    Where I copied libeay32.dll and ssleay32.dll

    I would then watch the logs on the ESXi console.

    Re-create the error, and then search for log entries that appear at the same time.  That should shed more light on what could be causing it.

    Good luck!

  • "Object reference not set to an instance of an object." on track

    Dear members,

    Today, I tried to "build and Run...". ' a rule base that I created some time ago and executed correctly. Now, I get the error "Object Reference." not set to an instance of an object When I try to run the basis of rules using Oracle Web determinations (construction is always successful). When I run the basis of rules by using "build and debug...". "no errors are presented and the basis of the rule is executed successfully as well. I can also access the basic rule in my web browser without having any problems. I expect that the cause of the problems lies in the recent installation of Google Chrome or Mozilla Firefox, but I don't know where to look for a solution. I already tried to install the latest version of the Oracle Policy Modeling, but the error has not been resolved by then.

    Dear Frank,

    Thanks for putting me in this direction. I never looked in the browser by default settings, because they never changed. In other words, Microsoft Internet Explorer is and has always been my default browser. Do even Mozilla FireFox or Google Chrome my default browser solved the problem (partially). Since we are analysts we of course want to know how the problem occurred. In addition, because the problem is not completely solved yet, it seems to be some sort of bug left in the Oracle strategy modeling.

    • I used the modeling of the Oracle strategy for six months without having any problems. The basis of rules was always run correctly in Microsoft Internet Explorer (which has been configured as the default browser).
    • I installed Google Chrome and Mozilla FireFox at the same time, but has not changed my default browser settings (so Microsoft Internet Explorer is the default browser).
    • Run a basic rule of now caused the "object reference is not set to an instance of an object." even if the default browser has been set successfully.
    • I changed the default browser to Google Chrome or Mozilla FireFox (which of the two is not serious) and rules was performed correctly in the specific browser.
    • I changed the default browser to Microsoft Internet Explorer, but the Oracle strategy modeling keeps using my default browser defined previously (Google Chrome or Mozilla FireFox).

    From there, I guess we can conclude that the Oracle Policy modeling does not resemble the right registry key to determine the default browser. In other words, Oracle Policy modeling is unable to identify Microsoft Internet Explorer as the default browser, where other applications (like Google Chrome and Mozilla FireFox) do this properly. I expect that the HKEY_CURRENT_USER\Software\Classes\http key is sought (which did not exist after I installed Google Chrome and Mozilla FireFox), but for the Windows operating system this key is only used until Windows XP. Windows Vista from the HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\http\UserChoice key should be used to find the default browser settings.
