Builders of the undefined reference and pointer...
OK, so I tried to make this work...
MyClass *example=new Myclass();
but it's not working, I don't know what to change...
Let's see an example:
newClass.h
#ifndef NEWCLASS_H_ #define NEWCLASS_H_ class newClass { public: newClass(); virtual ~newClass(); }; #endif /* NEWCLASS_H_ */
newClass.cpp
#include "newClass.h" newClass::newClass() { // TODO Auto-generated constructor stub } newClass::~newClass() { // TODO Auto-generated destructor stub }
applicationui.cpp
#include "applicationui.hpp" #include#include #include #include #include #include #include #include #include #include #include #include #include using namespace bb::cascades; ApplicationUI::ApplicationUI(bb::cascades::Application *app) : QObject(app) { // prepare the localization m_pTranslator = new QTranslator(this); m_pLocaleHandler = new LocaleHandler(this); if(!QObject::connect(m_pLocaleHandler, SIGNAL(systemLanguageChanged()), this, SLOT(onSystemLanguageChanged()))) { // This is an abnormal situation! Something went wrong! // Add own code to recover here qWarning() << "Recovering from a failed connect()"; } // initial load onSystemLanguageChanged(); newClass *temp=new newClass(); } void ApplicationUI::onSystemLanguageChanged() { QCoreApplication::instance()->removeTranslator(m_pTranslator); // Initiate, load and install the application translation files. QString locale_string = QLocale().name(); QString file_name = QString("FirstAppAlone_%1").arg(locale_string); if (m_pTranslator->load(file_name, "app/native/qm")) { QCoreApplication::instance()->installTranslator(m_pTranslator); } }
error:
C:\Users\imnotgoingtotellyoumyuser\ndk-10.2-workspace\FirstAppA\x86/../src/applicationui.cpp:93: undefined reference to `newClass::newClass()'
When files are added to the project, IDE adds them to the .pro or .pri file.
But this is not enough. Qmake must be launched to regenerate the Makefile file that is used for compiling. It seems that this step was not built in IDE, so clean & reconstruction is necessary.
I will test it and submit a JIRA ticket if this is the case.
UPD: confirmed. https://www.BlackBerry.com/jira/browse/tool-2393

Query the data reference and CFC
I would like to query once which returns a recordset and passing as reference data for functions in a ColdFusion component. Inside these functions, I take the query and then run a query of queries for the outcome of consolidation among other things. Is this possible? I get an error saying essentially that the query passed is not a simple value where I use it in the FROM clause in the query.
It works fine when both applications are in the same function, but it is unnecessary overhead to continually get the same data REF.
Example:
Template.cfm
-------------------
...
< name cfobject = component 'lib' = "mycfc" >
< component cfinvoke method = "" #lib # "="getQueryRefData"returnvariable ="refData"/ >"
"< component cfinvoke method =" "#lib #" = "getSum" returnvariable = "sum" refdata = "#refData #" / >
...
mycfc. CFC
--------------
...
< name cffunction = "getQueryRefData" access = "public" returntype = "query" >
< cfquery name = "allData" datasource = 'myDatasource' >
SELECT * RESPONSE
< / cfquery >< cfreturn allData >
< / cffunction >< cffunction name = "getSum" access = "public" returntype = "numeric" >
< cfargument "refData" type = name = "query" required = "yes" >
< cfquery name = "deptSum", dbtype = "query" >
Total Department, SELECT COUNT (*) AS
OF ARGUMENTS.refData < - mistake here - >
GROUP BY Department
< / cfquery >< cfreturn Val (deptSum.total) >
< / cffunction >
...
You're right, I left the in my original post. But they are in the actual code.
No, this is indeed the problem. Leave aside the signs #. It must be just ARGUMENTS.refData or refData, because it is the name of the query that follows 'FROM', not the subject of the application itself.

Hi all
I am writing this post with a heavy heart. I did research to buy a laptop for three months, and finally, I decided to buy HP laptop as laptops for HP computers reviews were good.
I bought the product (HP for laptop - 14-ac003ne) to the Kuwait on September 23 and went to India for holidays a week of. I started using the laptop and it was pointed out that there are a number of scratches of line on screen, completely unacceptable for a brand new product. Seeing this, I checked the logs, as well as the windows directory and pointed out that the laptop was one is not a brand new and it had from its windows and IIS in October 2014 information.
I'm really happy with the purchase and to return the laptop. Could you please tell if this is possible?
I go to the Kuwait this Saturday. Y at - it an email address to raise my concerns of HP sales management?
Thank you and best regards

Hello
It's my first time display questions on a forum like this, so I'll try to explain in detail what I have (somehow... :)).
Is it possible to have 2 "Program Files" location - one on the C partition - and the other on the D partition so that you can 'choose' where to install a program in particular? I don't really want to get rid from where 'move' the 'Program Files' folder on my C partition (I just do a clean reinstall of Windows XP), BUT I would like to be able to install several programs on the partition D place on C 'by default. "Here's the question: I have several programs that have no option to 'choose' where should be installed - they'll automatically C\Program Files. I want to install it on the D partition. If this is not possible, how can I transfer to the new location (once they have already been installed) in their entirety so that they are functional. I don't want to keep the remains, references and 'shortcuts' on the C partition. These programs should begin to malfunction, I have freedom to wipe the D partition and reinstall the programs without messing up the heart of the system.
I'd appreciate any help, advice and ideas. Regarding my computer experience, I'd put myself in the novice category, detailed explanations would be a lifesaver! Thank you.

undefined reference to the own class constructor
I have some material in my project subfolders and use include it with the full path to add:
#include
It compiles fine, but when I try to create the object I get this error:
undefined reference to `DataServiceConfig::DataServiceConfig(QObject*)'
what I am doing wrong?
Usually, this happens when you have this in your include file:
class MyClass
{
public:
MyClass(MyThing*);
private:
MyThing * m_thing;
};
but this isn't in your MyClass.cpp:
MyClass::MyClass (MyThing * thing):
m_thing (Thing)
{
}
In other words, you have the statement - so things that use your class compile - but you do not have the implementation, the linker complains that it can't find it.

I searched some tutorials showing how to use SpeedGrade. I'm now comfortable with the UI enough to use after seeing these: http://www.youtube.com/user/AdobeTV/videos?query=speedgrade
I am looking for tutorials that explain how to do a couple of things, first of all, I want to be able to remove color casts. In photoshop to do this you can use a curves layer and the use of the whole white point color chart and click somplace that is supposed to be white. and to the Prime Minister, you could do something similar with the color correcting fast. So basically that I'm looking for a way to target an area within a framework that should generally be grays, in the Anime, the eyes always be shades of gray, is as well as what I would target usually when you work with anime in photoshop first. If anyone knows a tutorial that shows how to do this type of color cast removal color correction in SpeedGrade could you please share a link.
Some of anime the older 80 and 90 on the film, the film has aged and that's where the color cast came. There is also a loss of color information in all areas. For example in the image below. Heaven is supposed to be blue instead of green teal/sea.
Another thing is back in the 80s and 90s many anime worked limited color palletes; something like maybe 16 colors in total, so many colors are used repeatedly. Thus, even with only a limited amount of reference material, I'd be able to get the corrections close. (I have no clips of reference for every single episode, only a handful of scenes from a handful of episodes).
I have a few reference documents showing approximately what should be the color. So, my next question is if anyone knows of any tutorials/guides/videos showing how to use SpeedGrade to color correct a clip so that the colors match the colors used in a reference element
I was also wondering on automatic correction based on an element of reference, although I'm guessing that this isn't always possible.
When I looked at the websiminar: http://seminars.adobeconnect.com/_a227210/p738pxm9zs0/ about 43 minutes into it, a feature is shown that automatically adjust the color with a clip that contains a colorchart.
I was wondering if a tool like that could analyze a start to clip at the end, to create a palette of colors used, and then compare that to the colors used in another clip and correct them. (a feature like this would be probably more useful/precise in anime that it would be long, but who knows.)
Another question related to the user interface:
I had a question, the only place where I see to access the colorwheels is in appearance, my video tab, I'm trying, just manages to adapt to 100% in the monitor.
So I prefer to hide or reduce the different looks (maybe even with a keyboard shortcut) so that I can access the color tools it covers, I've attached a picture of what I'm talking about. I know pressing 'P' cache at the bottom and thought that maybe it already is a way to hide/minimize/reduce the aspect presets to access the tools behind them without narrowing down the size of the preview screen.
It's a hard thing to do. SpeedGrade has an estimator of the matrix which aims to draw a camera shot in reference, but it only works if there is a graph of Macbeth in the framework - and you of course that.
Short of writing a custom plugin, you will have to do it by hand - if there is a true 'gray' in the framework then the pickers for the 3WCC/FCC in first allows you to get the right temperature, and black/white levels can be removed to the limit with their pickers (assuming that something on one of the frames is supposed actually to be black or white). Fix nonlinear cast where the RGB layers are each affected by different curves is a much more complex process, and not automatable in everything I know. However, once the white point Beach and brightness are attached, you can still make some visual adjustments of the balance on a range of colors with secondary correction tools in the 3WCC.
If you use the first and you want more help with these tools, please ask in the Premiere Pro forum.

the different between the default constructors and complete this builders
I have in my grain I have two constractors
public Person() {}
}
public person (String id, String firstName, String lastName) {}
This.ID = id;
this.firstName = firstName;
this.lastName = lastName;
}
in servlet I test the following, they do the same job, so what's the difference between these two constractors?
Person person = new Person (id, firstName, lastName);
Person person = new Person();
person.setId (id);
person.setFirstName (firstName);
person.setLastName (lastName);
If the daughter class extends the class parent, if I need to use great I can use the default constructors?A few notes to clarify the terminology first.
I have in my grain I have two constractors
Initially, I planned to ignore this harmless typo, but since you have repeated, we will the work point and move it ouf of the path: it's + constr.uctor +.
the different between the default constructors and complete this builders
There is no such thing as a "full" constructor There are builders, and a single class may have several of them, which are differentiated by their argument list.
I assume you mean by "complete Builder" "constructor with arguments" (I dunno what is the official term for this, I'll try to find it in the specs, but that's a detail).Also note that the notion of "default constructor" is different from what you think:
Citing the [url http://java.sun.com/docs/books/jls/third_edition/html/classes.html#16823] JLS:If a class contains no statement of constructor, a constructor that takes no default setting is automatically provided:
(...) the default constructor takes no parameters and simply calls the constructor of the superclass without arguments.In your case (given the code provided), you mean "an explicitly declared constructor, which takes no arguments.
the different between the default constructors and complete this builders
In addition, there is no such thing as a manufacturer 'this '.
There are builders, who are declared (or by default), and there is This syntax, which allows to invoke a constructor.
Typical example:public class Price { /** * Creates a new price, with the specified amount and in the specified currency. */ public Price(int amount, String currency) { this.amount = amount; this.currency = currency; } /** * Creates a new price, with the specified amount and in the default currency (US $). */ public Price(int amount) { this (amount, "USD"); } /** * Creates a new price, with a zero amount and in the default currency (US $). */ public Price() { this(0); } }
* If the daughter class extends the class parent, if I need to use great I can use the default constructors?
If your question is "I can invoke any superclass constructor, including the default?", then the answer is almost Yes (it's 'Yes, you can call a constructor that is visible to the subclass' - visibility here is in terms of public/protected/package ).
Example:
public class Mafioso extends Person { public Mafioso(String firstName, String lastName) { super(firstName, "The Silencer"); // Mafiosi usually don't like being known by their actual last name } public Mafioso() { super(); } }
Note that you can call the constructor of the superclass No. - arg (see super() invocation above), as soon as such a no. - arg constructor exists and is visible, no matter if you explicitly declared, as in your person class, or is this a compiler-generated default constructor.
I hope this helps. Kind regards
J.

I have emails that require some points to address such as "Please fix leak in the bathroom sink' and then the next line will be another application and so on. I would like to answer each question at the end of each line with a response (preferably in a different color to stand out police) such as "Yes - will fix" or "that cannot be done" or "you'll have to fix that yourself." So, I want to send this reply to the original sender.
It is probably easiest to copy and paste the initial list of questions in your answer, first of all and then add your comments.
If you have the problem that the list numbers change when you try to add your comment about a new line, try to make your line breaks using shift + enter instead of the entry.
