Destroy the definition component qml in c ++ destructor
I install some components, but they can only be destroyed if the application will be closed. Currently, a mistake is cause attesting that they are not made when the application is closed.
What I am unsure of is how to reference the alias or objectname to a definition of compoenent in c ++ and then destroy it.
ApplicationUI::~ApplicationUI() { // Destroy the sound manager. ComponentDefinition *myDef = bb::cascades::Application::instance()->findChild("myDef"); qDebug() << "Destroying Definition"; myDef->destroy(); }
Only, I was not able to find how to link the component definition in c ++ because it doesn't have a #include<>
If not, is there something in qml who inform me just before the application closes, so can I do this?
Normally, you can solve it by setting the parent of all objects you create in your definition. The parent must be something that you know will be destroyed when your application is closed, as the app itself class.
I don't think you should look for ComponentDefintion but because it's just a factory for components, you do not create. You should rather look for the type of object that creates the definition.
Also, do you you know that some objects of Cascades don't clean up after them properly and may generate errors no 'no' even if you do everything right. Why don't post it your console error messages because it can help you get an answer better than this one.

The destroyed fast compilation component List
Hello!
Last wek I updated Adobe Flash CC 2014 and also Air SDK 17. I realized I'm not be able to disable the quick compilation.
So I tried and the List component shows all of the items are selected. It seems that all the elements are selected.
On the IPAD, it looks like this. everything seems to be selected
On the desktop, it's okay.
Help, please.
Michael
It sounds like the question I raise first with SDK 16 in December, which I moved to 17 SDK in this post confused AIR SDK 17 iOS list skins - still not fixed. But in my post, I show how I managed to get around some of the question.

destroy the page created with C++
Hello
How do I destroy a thrust from a NavigationPane page when the page is created with C++.
Here is the code:
// applicationui.cpp Page* ApplicationUI::doLoadPageDetails(QString fn) { QmlDocument *qml = QmlDocument::create("asset:///PageDetails/PageDetails.qml").parent(this); [...] Page *newPage = qml->createRootObject
(); return newPage; } When I open the app displays a ListView. When I push on one of the elements in the list the PageDetails page is shown.
// main.qml [...]onTriggered: { var selectedItem = dataModel.data(indexPath); var page = app.doLoadPageDetails(selectedItem.toString()); navigationPane.push(page); }
Now, I have written a delete action in the application.cpp
void ApplicationUI::popFinished(bb::cascades::Page* page) { delete page; }
and used in the main.qml in onPopTransitionEnded:
onPopTransitionEnded: { // Destroy the popped Page once the back transition has ended. app.popFinished(page); }
But it's not destroy the page. Can someone tell me how to get destroyed page when you press the ButtonBack?
The count method gave me what I expected when I start the application number is 1-> home page.
When I click on an item on the next page open-> count = 2.
When I come back-> count = 1.
But I solved the problem.
The second page is filled with information from functions in C++. So in my additional popFinished function on page "Delete" now also clear the list of contacts with the clear function, as I said before.
void ApplicationUI::popFinished(bb::cascades::Page* page) { Contacts.Clear(); delete page; }

Destroy the NavigationPane Page when used of a Peek
Hello
It is possible to destroy a page when the rear sweeping gesture (peek) is used to jump to the page of the NavigationPane? I don't want to use the property ' peekEnabled: false "I like the gesture of glance. I can't use the signal to onPopTransitionEnded I don't know the id of the page that will be skipped (using ComponentDefinition).
The following is a snippet of the code:QML File 1: NavigationPane { id: navPane CustomControlPage{ } } CustomControlPage.qml Page{ ... onTriggered:{ // I need to create a new Object everytime and that is causing the problem when peek gesture is used rather than back button as with backButton, I can just use paneProperties and then do pageID.destroy(); var newPage = newCustomPage.createObject(); newPage.variant1 = "hello,"; newPage.variant2 = "world!" navPane.push(newPage); } attachedObjects:[ ComponentDefinition{ id: newCustomPage source: "newCustomPage.qml" } ] } newCustomPage.qml Page { id: newPage property variant variant1 property variant variant2 ... paneProperties: NavigationPaneProperties{ ActionItem{ title: "Back" onTriggered { newePage.destroy(); } } } }
Thank you!
Yes, that's correct. 'page' is a parameter, it points to the page that you need to destroy.
popTransitionEnded is called when the page is closed using a "back" button or closed using the gesture of glance.
It cannot be called if you delete the page programmatically, I'm not sure about this.

Can not access the context in QML property
So I have an arraydatamodel in the CPP file, I use qml-> setContextProperty (...) to set it up to allow QML to access, the strangest part is, no matter if I put it in navigationPane Page or a container, it keeps saying can't find not variable, but in the same QML in ListView, they can access it without a problem. The other weird part, it is an another QML is able to access it in the tag of the page, the same model.

You must call setContextProperty before calling createRootObject.

Whenever I try to start Windows Movie Maker, I get the following error:
"Sorry, cannot start Windows movie maker. Make sure your satisfied computer minimum system requirements before you try to start the Movie Maker and then try to update the driver for your video card if Movie Maker does not start".
I know that my computer meets the minimum system requirements because it came with the whole package. I've also updated my video driver correctly several times. I even uninstalled Movie Maker, re-installed. Even uninstalled the complete set of Windows Live and re-installed, but it still does not work. After a lot of searching for answers, I found the event log in which this error:
«Activation context generation failed for "C:\Program Files (x 86) \Windows Gallery\MovieMaker.Exe".» Manifest error or policy of the folder "C:\Program Files (x 86)" \Windows Live\Photo Gallery\WLMFDS. "." DLL"on line 8. Component identity found in manifest does not match the identity of the requested component. Reference is WLMFDS, processorArchitecture = "AMD64", type = "win32", version = "1.0.0.1". Definition is WLMFDS, processorArchitecture = "x 86", type = "win32", version = "1.0.0.1". Use sxstrace.exe for detailed diagnosis. »
I don't know, but I think it's causing my movie maker does not start. I looked around even more of an answer to this question on how to resolve this error, and I couldn't find anything so far. Microsoft support said that I have nothing to do and it will solve automatically. Alas, I got this error whenever I tried to open Movie Maker (the time is equal to the time I tried to open it).
What can I do to fix this?
Thanks in advance.
Hello JurrianH,
You can go ahead and post in the forums alive in dealing with the problem with Live Movie Maker specifically. Please do not hesitate to answer, in the case where you are facing in the future other problems with Windows.

Underpayment to destroy the VM in vRA7
Hello. I run a POC in the House for vRA7 and that you have installed and configured a minimal deployment and have set up the deployment into a test vCenter.
Everything looks good and I have created a simple model to set up a virtual Windows machine. This works as expected and the deployment is complete, and I see the resulting virtual machine in my list of items.
However, when I try to destroy the configured virtual computer, I see the following error message
and the following text in the file catalina.out on the device.
catalina.out:2016 - 02-08 13:02:49, 111 vcac: [component = "coffee: catalog" priority = "NOTIFY" thread = "tomcat http - 29" tenant = "lab" context = "" token = "" "] com.vmware.vcac.platform.service.rest.resolver.RestApplicationExceptionHandlerResolver.logException:189 - execution of Manager has exception: you are authorized to perform ' {com.vmware.csp.component.cafe.composition@resource.action.deployment.destroy.name}' to the point ' Windows 2012-87782490'. '.
Service catalog has the action to destroy as a right.
version of the vRA is 7.0.0 Build 3292778
Looks like a schoolboy on my type error. I had the authorization to destroy on the plan of action, no not on deployment. Adding this solved my problem

Name of tables listing the definitions of Web Forms row\column\POV
All,
We have some applications planning and a lot of Web forms to allow entry in varied combinations of row\column\POV. Users, it is difficult to locate the correct online with the combination of right row\column\POV form, to allow them to enter data and have to open\close a large number of Web forms before they find the right pair they need\want.
I know that the relational component of a planning application includes many tables store the definitions of Web forms, etc.. I would like to know where I could find a list of the tables that contain the definitions row\column\POV of each Web forms for each planning application in order to quickly identify the correct webforms who could access their data entry of support staff.
Thanks in advance.

Help of Bean managed using the definition
I work to create a Managed Bean help for definition Help as described in "19.5.3 How to create the Managed Bean help ' section of the RPF Interface User Guide Developer Web ADF." With the help of JDev Version 11.1.2.1.0.
Thought I had all of the artifacts assembled, but when I run the message is: < ELHelpProvider > < _getTranslationMap > ELHelpProvider helpSourceExpression has the value zero.
Any suggestions would be greatly appreciated.
Here is the managed bean:
Here's the adf - setting.xml in sources of demand / META-INF:public class ELHelpProviderProjRequest extends ELHelpProvider { public ELHelpProviderProjRequest() { } /* To use the HelpProvider, the EL expression in the helpTopicId attribute must point to a Map, otherwise * you will get a coerceToType error. */ public Map<String, String> getHelpMap() { Iterator iterator = _HELP_MAP.entrySet().iterator(); while(iterator. hasNext()){ System.out.println("hash map entry " + iterator.next()); } return _HELP_MAP; } static private final Map<String, String> _HELP_MAP = new HashMap<String, String>(); static { // each element [put] can be for a separate helpTopicId attribute _HELP_MAP.put("MAPHELP_CATEGORY_CAPITAL_DEFINITION", "Map value for credit card definition"); _HELP_MAP.put("MAPHELP_CATEGORY_OTHER_DEFINITION", "Map value for credit card instructions"); } }
Here are the faces-config:<?xml version="1.0" encoding="windows-1252" ?> <adf-settings xmlns="http://xmlns.oracle.com/adf/settings" > <adf-faces-config xmlns="http://xmlns.oracle.com/adf/faces/settings"> <help-provider prefix="MAPHELP_"> <help-provider-class> com.corpnet.abc.util.ELHelpProviderProjRequest </help-provider-class> <property> <property-name>helpSource</property-name> <value>#{helpTranslationMap.helpMap}</value> </property> </help-provider> </adf-faces-config> </adf-settings>
In the inputText, here is the helpTopicId component:<managed-bean> <managed-bean-name>helpTranslationMap</managed-bean-name> <managed-bean-class> com.corpnet.abc.util.ELHelpProviderProjRequest </managed-bean-class> <managed-bean-scope>session</managed-bean-scope> </managed-bean>
<af:inputText value="Test" inlineStyle="font-weight: bold;" id="it31" simple="true" helpTopicId="MAPHELP_CATEGORY_CAPITAL" readOnly="true"/>
The two following changes should take care of this issue:
(1) the managed bean should not exceed ELHelpProvider, i.e.
public class ELHelpProviderProjRequest { ...
(2) in the adf - setting.xml use oracle.adf.view.rich.help.ELHelpProvider for the help-provider-class, i.e.
...
oracle.adf.view.rich.help.ELHelpProvider ... -

Color of text in af:tree with the definitions of two nodes
Hi all
I use JDev 11.1.1.5.0
I have an af:tree component that got two definitions of nodes (two different iterators). I want to display the data in other colors with other icons etc. According to the definition of node.
I wanted to use EL in the Style section in the properties of the af Component Inspector: tree, but I don't know how to get the node current definition name.<tree IterBinding="OrganizacjeGlowneIterator" id="OrganizacjeGlowne"> <nodeDefinition DefName="proby.model.views.ElorganizacjeView" Name="OrganizacjeGlowne0" TargetIterator="${bindings.OrganizacjeEditIterator}"> <AttrNames> <Item Value="Kod"/> <Item Value="Nazwa"/> <Item Value="Typorganizacji"/> </AttrNames> <Accessors> <Item Value="ElorganizacjeView" Label="strukturaOrganizacyjnaPageDef_OrganizacjeGlowne_proby.model.views.ElorganizacjeView_ElorganizacjeView"/> <Item Value="StanowiskaUsersView" Label="strukturaOrganizacyjnaPageDef_OrganizacjeGlowne_proby.model.views.ElorganizacjeView_StanowiskaUsersView"/> </Accessors> </nodeDefinition> <nodeDefinition DefName="proby.model.views.StanowiskaUsersView" Name="OrganizacjeGlowne1" TargetIterator="${bindings.StanowiskaUsersEditIterator}"> <AttrNames> <Item Value="NazwaStanowiska"/> <Item Value="ImieUsera"/> <Item Value="NazwiskoUsera"/> <Item Value="EmailUsera"/> </AttrNames> <Accessors> <Item Value="StanowiskaUsersView_2"/> </Accessors> </nodeDefinition> </tree>
How to change color dynamically based on the current definition of node?
Any help will be appreciated.
Kind regards
Wojtek.Hello
This EL
#{node.hierTypeBinding.structureDefName}
Returns the name of the name of the View node and package object
If you could do
#{node.hierTypeBinding.structureDefName == "proby.model.views.ElorganizacjeView"? Red: white}
for the nodes of color code

Essbase Excel error: install the COM component.
Hi all
I am facing problem in essbase excel plug-in software component. I am using MS excellent worm 2002 SP3. After the connection to the database essbase via software component excel plug-in, when I double click on cell A1 in excel, it tries to install the COM component http://activex.microsoft.com/objects/ocget.dll and after that the screen each time, nothing coming.
Even if I want to get the names of members of essbase through "member selection" Add essbase, he does things as usual, but no member name appears in excel.
After you uninstall and reinstall the essbase add in(i.e. the analytic server client) atleast 2 or 3 times, no solution came.
Could someone help me with these questions. Please return back as soon as possible.
Thank you and best regards,
REDAIs it possible that the combination is be the first record? If so, I would say that check properties of the Data Source of the rule of your load for a definition header which is not matched correctly (i.e. the number of lines to skip = 1, whereas it should be 0).
It is the only reason I could imagine that a combination of record is not loaded in a load rule by also valid.
