• Error: 0xc000012f and the KERNEL DATA PAGE FAULT

  My son has a laptop of game.  Since last week, he experienced extreme problems.  A constant if the following errors: 0xc000012f and the KERNEL DATA PAGE FAULT.  Although I'm not technologically savvy, I tried the obvious in running virus scan and visiting different communities for troubleshooting tips.  When you run the antivirus (paid service) analysis, the system hangs and the system restarts.  I attended ASUS website in the hope of getting more advice than to have to provide access to the laptop of my son to a technician who gave me some insurance for the better part of 45 minutes that he help and troubleshooting problems.  He highlighted a very detailed chart of downtown action (reliable?), which looked pretty serious.  Suffice it to say, the conversation ended when he asked a one-time fixed fee of $200.  When I refused, he went to stop everything.  I would simply like to take any action that will further damage the laptop of my son. I paid $3K for this system.  Is someone can you please help me solve these problems?  I was going to buy a registry cleaner but was informed in an online community chat room not to do so that these products are not reliable.  Thank you all in advance for your review and taking the time to help me.

  You reload the XML file every 100 milliseconds, I'm not surprised
  the memory usage increases...

• [Explanation necessary] Clears the listview data and fill it again with new data

  Hello

  I correctly filled a listview in c ++, data analysed and does interesting things with it. However, I am drunk stumbling, unable to find a way delete and repopulate my display of the list...

  Question 1:

   

  1. How can after I insert data in the list view, I clear the list data and run again the same method (init) who populated the list view with the data in the first place?

  Here are the docs that I referenced and I don't understand how to implement the methods in my code.

  QList - clear() method

  https://developer.BlackBerry.com/Cascades/reference/QList.html#clear

  Using the data access Code, example
                            data_access/using_data_source

  GroupDataModel - Clear()

  https://developer.BlackBerry.com/Cascades/reference/bb__cascades__groupdatamodel.html#clear

  CODE
  
  Here is my code - filling of the display of the list of C++ and display of data in a ListView.

  MyApp.cpp

  MyApp::MyApp(bb::cascades::Application *app)
  : QObject(app){
      // create scene document from main.qml asset
          // set parent to created document to ensure it exists for the whole application lifetime
          QmlDocument *qml = QmlDocument::create("asset:///main.qml").parent(this);
  
              AbstractPane *root = qml->createRootObject();
              qml->setContextProperty("yoyo",this);
              //grab references
              list_view = root->findChild("listView");
  
              // set created root object as a scene
              app->setScene(root);
  
              mNetworkAccessManager = new QNetworkAccessManager(this);
              bool result = connect(mNetworkAccessManager, SIGNAL(finished(QNetworkReply*)), this, SLOT(requestFinished(QNetworkReply*)));
  
               Q_ASSERT(result);

  Question 2:

  How reference to the ListView object with the name "listView" in different parts of the MyApp.cpp file? Is there anything else I should add to the header file to make the accessible listView?

  Question 3:

  What happens when you call the clear() method? How the data model is affected? How the user interface is affected? What happens in memory?

  Question 4:

  How do you verify that the data in the list has been deleted so that you can go ahead and fills again with new data? What is the cheque that I perform?

  I would also like to know how you manage multiple views of lists and data sources in your applications. Best practices or ideas?

  Thank you
  

  I was able to clear the listview with the following code, if anyone is interested.

  listView.dataModel = null
  

  The dataModel must be set to "null".

• Date page does not appear first drop the bar down

  Just downloaded the new ios and found that the Notification Center page appears first when you use the new bar drop down. I have to keep pulling down then drag to the right to display date apps, weather, news, etc.

  How can I configure it so that I can view the main page widget first, when you pull down the drop to the low bar and not the notification page?

  Thank you!

  Just drag to the right at the beginning.  No need to blow first.

• Trouble sometimes with WebView short Web page rendering

  I noticed sometimes in my application poorly rendered Web pages in a WebView because the webview appears dynamically size itself so that it is only as high as it should be... so if something to Center vertically, it appears at the top of the screen, not the vertical middle of the screen. There was even a Yahoo/Facebook login page that started small and has started to grow a few pixels per second!

  I tried to add:

  verticalAlignment: VerticalAlignment.Fill

  ... for the WebView to the ScrollView as if it is contained in and to the container that contains the ScrollView, but that doesn't seem to help.

  I found another post on the forum that answers this question:

  WebView {
      ...
      preferredWidth: Infinity
      preferredHeight: Infinity
  }

• Notify the ListView data in the model have changed

  Hello!

  I know this question has been asked several times, but I have yet to find anything satisfactory.

  I have a ListView, filled with a QListDataModel.

  After some time I update an element of the model. So far, the only way I found to the ListView so that this change is to delete the model and then reappend all elements. But the problem with this approach is that ListView Flash and scroll to the top of the page. Is there anything better to just say ListView that it should update the visible elements?

  Thank you

  Well, I just signal myself in the WRITE method and it works.

• Incorrect Listview data list JSON

  Hi all

  Small question here I work on all day but I can't seem to understand. My application gets the JSON data in a database online. The JSON data looks like this:

  {
    "legislations": [
      {
        "databaseId": "cas",
        "legislationId": "rsc-1985-c-a-1",
        "title": "Access to Information Act",
        "citation": "RSC 1985, c A-1",
        "type": "STATUTE"
      },
  
  (...)
  

  For some reason, in the ListView, the key of "reference" is displayed (for example, for this entry, ' R.S.C. 1985, c. a - 1 ' will be displayed), no title. I'm confused because I don't talk to you even the word 'quote' in my code!

  Even more confusing, I am able to sort keys by title, so the list is in alphabetical order, but I can't get the titles will appear!

  Here is my code so far:

  (...)
  
  ListView {
              id: browseLegList
              dataModel: legBrowsDataModel

• How to upgrade data using load data page?

  Hi all

  im doing a migration page where my user will provide the csv file, so I could load into my table. problem is that loading data using apex collection so I know columns are limited, but I forgot how. (probably 40 something).

  So I decided to split the csv file with the two files with a common column, which is a key. If im guessing two files can be linked using this key. However when I upload the second file, he will still do an insert instead of update action. How updated? is this what I need to set or activate?

  just to check that I tried to download the csv... and then changed some content inside and re upload... even if I that.it always inserts instead of update. Can anyone share how can I update? It's really important because I have a lot of columns to download. so in my situation, the best way is to separate files.

  Help, please...

  In components, under the loading of data shared. On the model of your table, you specify the unique columns (up to 3). I believe that if there is no match, it will insert. If it finds a matching record, it will update. So if you have a single column that is in each worksheet, you must specify here

• < netui-data: pager > action to extract lines dynamically

  Hello
  
  How can I configure a pager of DataGrid to dynamically extract lines when a user through the paging swap pages?
  I know that I can read all my lines to a collection / array before the rendering of the datagrid control and set the pager to iterate on it like this:
  
  [Controller]
  
  Private list < Ride > wrinkles;
  
  public list < Ride > getRides() {}
  return of the rides;
  }
  
  [Action]
  wrinkles = rideDBControl.getAllRides (); huge amount of data
  ...
  back to the front;
  }
  
  [JSP]
  
  "< div style =" "border-width: 2px;" > < netui-data: dataGrid name = "currentRidesGrid" dataSource = "pageFlow.rides" >
  < netui-data: configurePager pagerFormat = "prevNext" pageSize = "${pageSize}" / >
  < netui-data: header >
  < netui-data: headerCell headerText = "Name" / >
  < netui-data: headerCell headerText = "Description" / >
  < / netui-data: header >
  < netui-data lines: >
  < netui-data: spanCell value = "${container.item.name}" style = "background-color: #f0f0f0; do-size: 14pt; ">
  < / netui-data: spanCell >
  < netui-data: spanCell value = "${container.item.description}" >
  < / netui-data: spanCell >
  < / netui-data lines: >
  < / netui-data: dataGrid > < / div >
  
  But how can I make the pager call a method to update the content of the collection "wrinkles" according to the current selected page and the size of the page? And how do I get the current page and the size of the page inside this method?
  I want to be paginated queries that may return a huge amount of data (1 m + lines), so extract all lines at once is impossible. What I want to do, is spreading the current page and the page size of pager to a method that will update the current collection according to a query such as:
  
  Select X, Y, Z
  Table
  Where the...
  And ROWNUM BETWEEN page * pageSize AND (page + 1) * pageSize
  
  Can someone help a noob?

  For more information, I found the answer by myself.

  To retrieve the rows dynamically, you must change the tag , and include the attributes a pageAction and partialDataSet, for example:

  Within the action of pagination, you can get the current size of the line and page of a PagerModel object. You can then update the data source (don't forget to call the setDataSetSize providing the length of the entire data so that the pager shows the right amount of pages), for example:

  @Jpf.Action (forward = {@Jpf.Forward (name = "success", access = Jpf.NavigateTo.currentPage)})
  {public pagination() before
  DataGridStateFactory dataGridStateFactory = DataGridStateFactory
  .getInstance (getRequest ());
  Gets the pagerModel for the grid object
  PagerModel pagerModel = dataGridStateFactory.getDataGridState)
  "currentRidesGrid") .getPagerModel ();
  => Code to get the size of any data source<>
  pagerModel.setDataSetSize (dataSourceSize);
            
  Get the first line and the model page size
  int firstRow = pagerModel.getRow ();
  int pageSize = pagerModel.getPageSize ();
            
  => Code to extract the rows to display<>
  wrinkles = pageRides;
            
  Forward, forward = new Forward ("success");
  back to the front;
  }

  I hope this helps.
