Subtitles out of sync Samsung PS51D6900; Subtitles out of sync in Samsung’s plasma TV 50’’

Subtitles in Samsung plasma does not always work as we would like them to. I had several movies which had problems with subtitles. It turned out that it was a problem with frame rate (of 25 frames/s in my case) which Samsung’s plasmas interpret in a wrong way. The symptoms were as follows: subtitles worked correctly in Media Player Classic Home Cinema (link) but failed to work on the TV.

The problem was that these subtitles were FRAME-based. It means that the format was like this:

{3955}{4015}Do roboty!
{4021}{4112}Potrafisz byµ dupkiem, jeśli chcesz.
{4165}{4230}Głupia dziwka.
{4300}{4354}Zamknijcie lokal, gdy skończycie.

That is: {Beginning_frame}{Ending_frame}

If you want the subtitles to work in both: MPC-HC & Samsung plasma you need to convert them to srt format which looks like this:

11
00:00:53,520 --> 00:00:55,760
Czyli dobrze usłyszałem.
Powtarzasz to co roku.

12
00:00:55,920 --> 00:00:57,720
Tak, ale tym razem mówię poważnie.

13
00:00:57,880 --> 00:00:59,320
W końcu żyje się tylko raz.

14
00:00:59,480 --> 00:01:00,440
Pewnie.

 

Generally ANY format which is TIME-based should work. A nice program for converting subtitles to time-based formats is here. You can download a version here as well.

Visual Studio 2010 reference other project from the same Solution

- Add a reference to that Project int the Project you're trying to access foreign classes from
  (Add reference-Projects-Foreign_Project)
- Make sure when compiling (debug), your solution platform is set to "Any CPU"
- Make sure they both are referencing the same .Net 4 Profile, one may be using the client profile

Joomla - Re: JAuthentication::__construct: Could not load authentication libraries

I disabled the plugin - Authentication – Joomla as I thought it was for user logging in the page, not the admin login. It was a big mistake though. To turn this feature on you need to log to Joomla’s database and change published to 1 in the jos_plugins table  in row.Name = Authentication – Joomla (it was row.id = 1 in my case).

UPDATE `your_database_name`.`jos_plugins` SET `published` = '1' WHERE `jos_plugins`.`id` =1;

Autofac register class with different constructors; Autofac registering and constructor priority

This examples exaplains the basic operation of constructor priority in Autofac which is a dependency injection framework simmilar to spring.

 

class MemoChecker{

Simple command in MVVM model, Silverlight, C#

MVVM model:

• Model - behaviour and data management
• View - renders model into UI
• ViewModel - "model of the view"; data binding between view and model;

This example shows how to create a button with an event "Save" bound to it in MVVM model.

In application's shell (MainPage.xaml) we define UpperPanelView resource and insert the body of UpperPanelView.

MainPage.xaml:

<UserControl x:Class="SilverlightMVVM.MainPage"
    ....
    xmlns:basicviews="clr-namespace:SilverlightMVVM.Views">
    <UserControl.Resources>
        <basicviews:UpperPanelView x:Key="UpperPanelView"/>
    </UserControl.Resources>

    <Grid x:Name="LayoutRoot" Background="White">
        <basicviews:UpperPanelView Grid.Row="1" DataContext="{Binding Source={StaticResource UpperPanelView}}"/>
    </Grid>
</UserControl>

UpperPanelView has a button with a command Save bound to UpperPanelView.Save property.

UpperPanelView.xaml:

<UserControl x:Class="SilverlightMVVM.Views.UpperPanelView"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d"
    d:DesignHeight="150" d:DesignWidth="402" xmlns:sdk="http://schemas.microsoft.com/winfx/2006/xaml/presentation/sdk">

    <Grid x:Name="LayoutRoot" Background="White">
        <sdk:Label Height="28" HorizontalAlignment="Center" Margin="42,12,54,0" Name="label1" VerticalAlignment="Top" Width="306" Content="Upper panel" FontSize="20" FontWeight="Bold" />
        <Button Content="Save" Height="23" HorizontalAlignment="Center" Margin="159,59,169,0" Name="saveButton" VerticalAlignment="Top" Width="75"
                Command="{Binding Save}" CommandParameter="{Binding ElementName=listImages, Path=SelectedItem}"/>
    </Grid>
</UserControl>

UpperPanelView.xaml.cs hold the Save property of type SaveCommand. We have bound button click property to this event earlier.

UpperPanelView.xaml.cs:

public partial class UpperPanelView : UserControl
{
    public UpperPanelView()
    {
        InitializeComponent();
    }

    //Commands
    private SaveCommand _saveCommand;
    public SaveCommand Save
    {
        get
        {
            if (_saveCommand == null)
                _saveCommand = new SaveCommand(this);
            return _saveCommand;
        }
    }
}

SaveCommand implements ICommand interface and so has the implementation of the Save command.

SaveCommand.cs:

public class SaveCommand : ICommand
    {
        private UpperPanelView _viewModel;

        public SaveCommand(UpperPanelView viewModel)
        {
            _viewModel = viewModel;
        }

        public bool CanExecute(object parameter)
        {
            //return (_viewModel.SelectedCapture != null) ? true : false;
            return true;
        }

        public void Execute(object parameter)
        {
            MessageBox.Show("Ala ma kota");
        }

        public event EventHandler CanExecuteChanged;

        protected virtual void OnCanExecuteChanged(EventArgs e)
        {
            var canExecuteChanged = CanExecuteChanged;

            if (canExecuteChanged != null)
                canExecuteChanged(this, e);
        }
    }

============================================

Another example:

MessageBrowserView.xaml
------------------------
<Button Content="A" Command="{Binding MenuItemClickCommand}"></Button>

MessageBrowserView.xaml.cs
----------------------------
public MessageBrowserView(MessageBrowserViewModel viewModel)
{
  DataContext = viewModel;
  InitializeComponent();
}

MessageBrowserViewModel.cs
---------------------------

public MessageBrowserViewModel()
{
MenuItemClickCommand = new ActionCommand(MenuItemClick);
}

/// <summary>
/// Komenda odpowiadająca na kliknięcie w Menu
/// </summary>
public ICommand MenuItemClickCommand { get; private set; }

private void MenuItemClick()
{
     MessageBox.Show("AAAA");
}

WPF toolkit datagrid usage; WPF datagrid column size;

The datagrid for old WPF (from Visual Studio 2008) is available as an addon from WPF toolkit project. WPF toolkit is available here. Source code for this example is available here. In this example one creates a class holding data in the grid (GridRow). Instances of this class are held in an ObservableCollection. It has to be ObservableCollection because only then changes in the collection will be reflected in the grid. You could use a simple List but the Grid will not update new information then.

Later on you set the grid’s ItemsSource as the ObservableCollection created earlier on.

 

        In XAML file:
       
    <dg:DataGrid AutoGenerateColumns="True"  Height="433" Name="dataGrid1" Width="809" Canvas.Left="4.999" Canvas.Top="55"  Margin="5" SelectionChanged="dataGrid1_SelectionChanged" AutoGeneratedColumns="dataGrid1_AutoGeneratedColumns">
        </dg:DataGrid>
       
       
        In cs file:
       
        public class GridRow
        {
            public string Nr { get; set; }

            public string Lp { get; set; }

            public string Name { get; set; }

        }
       
        public static ObservableCollection<GridRow> GetSampleCustomerList()
        {
            ObservableCollection<GridRow> aaaa = new ObservableCollection<GridRow>();
            GridRow gr = new GridRow();
            gr.Nr = "10345";
            gr.Lp = "1";
            gr.Name = "Janina";
            aaaa.Add(gr);
        }
       
        private void constructDataGrid()
        {
            dataGrid1.ItemsSource = GetSampleCustomerList();
        }
       
        private void dataGrid1_AutoGeneratedColumns(object sender, EventArgs e)
        {
            dataGrid1.Columns[0].Width = 55; //Nr
            dataGrid1.Columns[1].Width = 46; //Lp
            dataGrid1.Columns[2].Width = 140; //Name
        }
       

Flex Pie chart; Flex how to use Pie charts; Flex sample testcase counting pie chart;

This example shows how to create a Pie chart that counts test cases (it can be anything else, of course). Source code is available here.

Pie chart is bound to an ArrayCollection (don’t forget to insert [Bindable] property – without it the Pie chart won’t work of course). The showDataTips="true" property displays nice percentage information in Flash when you hover your mouse over it. resultHandlerStatCorrectTCs and resultHandlerStatFailedTCs are async functions that gather data for the Pie chart.

 

<mx:PieChart x="50" y="90" id="piechart1" dataProvider="{tcPercResults}" showDataTips="true" width="300" height="300">
    <mx:series>
        <mx:PieSeries displayName="TestCases" field="Amount" nameField="Expense" explodeRadius=".12"/>
    </mx:series>
</mx:PieChart>
<mx:Legend dataProvider="{piechart1}" x="0" y="90"/>

 

//Statistics
[Bindable]
public var tcPercResults:ArrayCollection = new ArrayCollection([
    {Expense:"Failed", Amount:2000},
    {Expense:"Success", Amount:1000},
]);
   
   
   
protected function statCanvas_creationCompleteHandler(event:FlexEvent):void
{
    //get correct TCs
    var resultObjCorrectTCs:AsyncToken;
    var responderCorrectTCs:AsyncResponder = new AsyncResponder( resultHandlerStatCorrectTCs, faultHandlerForAsyncCall );
    resultObjCorrectTCs = testService.getCorrectTCCount();
    resultObjCorrectTCs.addResponder( responderCorrectTCs );
   
   
    //get failed TCs
    var resultObjFailedTCs:AsyncToken;
    var responderFailedTCs:AsyncResponder = new AsyncResponder( resultHandlerStatFailedTCs, faultHandlerForAsyncCall );

WPF clone tabItem; WPF create TabItems dynamically; WPF cannot edit TabItems controls; WPF cannot access TabItems controls;

It is impossible to clone TabItems from an existing one without using XamlReader and XamlWriter. You can, however, define a template for creating new TabItems. The template has to be created in your xaml file in Window resources.

<Window.Resources>
  <DataTemplate x:Key="tabItemContent">
            <Canvas Margin="0,0,0,0" Name="tabPracownikCanvas" Visibility="Visible">
                <ListBox Canvas.Left="0" Canvas.Top="-0.004" Height="229.977" Name="listBox1" Width="152.207">
                    <ListBoxItem>Dane osobowe</ListBoxItem>
                    </ListBox>
                <RichTextBox  Canvas.Left="0" Canvas.Top="261.085" Height="246.642" Name="richTextBoxBasicInfo" Width="152.207" IsReadOnly="True"/>
                <Label Canvas.Left="0" Canvas.Top="233.31" Height="27.775" Name="label1" Width="152.207" Content="SomeTextHere">
                </Label>
                <Canvas Canvas.Left="155.54" Canvas.Top="-0.018" Height="507.745" Name="canvasWithDetailedInfo" Width="430.731" >
                </Canvas>
            </Canvas>
        </DataTemplate>
</Window.Resources>

To add new tabItem just do the following:

TabItem item = new TabItem();
item.Header = "New item";
item.ContentTemplate = TryFindResource("tabItemContent") as DataTemplate;
tabControl2.Items.Add(item);

YOU CANNOT change the contents which were created dynamically just through children editing. You need to bind some properties.

e.g. we will bind label contents:

create a class:

        class Person
        {
            public string Name { get; set; }

            public string Surname { get; set; }
        }

change the label content to binding:

<Label Canvas.Left="0" Canvas.Top="233.31" Height="27.775" Name="label1" Width="152.207" Content="{Binding Name}">

change the Item’s content:

item.Content = new Person() { Name = "dupa", Surname = "xxxx" }

It will automatically change the label’s content when you change item.Content.Name property.

 

Flex ctrl+r key press; Flex ctrl+f key press; Flex ctrl+F key press

 

To intercept the above key presses you need to register an event handler (possibly in an init function or any onCreation event) like this:

stage.addEventListener(KeyboardEvent.KEY_DOWN, mainWindow_keyDownHandler);

The function looks as follows:

protected function mainWindow_keyDownHandler(event:KeyboardEvent):void
        {
            if (event.ctrlKey && event.charCode == 114)//ctrl+r
            {
                button2_clickHandler(null); //refresh
            }
           
            if (event.ctrlKey && event.charCode == 102) { //ctrl+f
                button3_clickHandler(null); //custom filter
            }
           
            if (event.ctrlKey && event.shiftKey && event.charCode == 70) { //ctrl+F
                button1_clickHandler(null); //full screen
            }
        }
