Are the filesystems VFAT and FAT32 the same, or are there any differences between them?

What is the difference between VFAT and FAT32 file systems?

I am having a WPF window, with a background image of one file in my local system. So the XAML file looks like this:

     &lt;Window.Background&gt;
        &lt;ImageBrush ImageSource=&quot;/MYASSEMBLY;component/Resources/MyPic.png&quot;/&gt;
     &lt;/Window.Background&gt;

In the XAML designer it actually shows this background image, so the image does exist in MYASSEMBLY\Resources folder. However, in the `InitializeComponent()` function call when I launch the application, it throws the exception

&gt; Cannot locate resource &#39;resources/mypic.png&#39;.

So I am totally lost now. Are the directories different between the design and runtime so doesn&#39;t exist in the runtime?

WPF throws &quot;Cannot locate resource&quot; exception when loading the image

I am having a WPF window, with a background image of one file in my local system. So the XAML file looks like this:
<pre><code class="hljs language-php-template"> &#x3C;Window.Background>

 &#x3C;/Window.Background>
</code></pre>
In the XAML designer it actually shows this background image, so the image does exist in MYASSEMBLY\Resources folder. However, in the <code>InitializeComponent()</code> function call when I launch the application, it throws the exception
> Cannot locate resource 'resources/mypic.png'.
So I am totally lost now. Are the directories different between the design and runtime so doesn't exist in the runtime?

MessageText property gets updated only when I hit another control. What is more if I press any button it&#39;s Click handler isn&#39;t executed and the MessageText set is executed instead. I&#39;ve broken my head.

    &lt;TextBox x:Name=&quot;messageText&quot; Grid.Row=&quot;1&quot; Grid.Column=&quot;0&quot;
             TextWrapping=&quot;Wrap&quot; Text=&quot;{Binding Path=MessageText, Mode=TwoWay}&quot;/&gt;


&lt;!----&gt;

    private void ChatView_Loaded(object sender, RoutedEventArgs e)
    {
        DataContext = viewModel;
    }

&lt;!----&gt;

    public string MessageText
    {
        get
        {
            return this.messageText;
        }
        set
        {
            this.messageText = value;
            OnProperyChanged(&quot;MessageText&quot;);
        }
    }

Textbox binding update in WPF

I have the following code:

    &lt;DockPanel&gt;
        &lt;StackPanel DockPanel.Dock=&quot;Top&quot; Orientation=&quot;Horizontal&quot;&gt;
            &lt;RadioButton Content=&quot;_Programs&quot; 
                        IsChecked=&quot;{Binding Path=ProgramBanksSelected}&quot; IsEnabled=&quot;{Binding Path=ProgramsEnabled}&quot; Margin=&quot;8&quot; /&gt;
            &lt;StackPanel&gt;
                &lt;Label Content=&quot;Master&quot; Height=&quot;28&quot; Name=&quot;MasterFileStatus&quot; VerticalContentAlignment=&quot;Center&quot;/&gt;
            &lt;/StackPanel&gt;
        &lt;/StackPanel&gt;
        ...

The radio button should be placed on the left side in the stack panel (I removed some buttons for not cluttering the example) and the label (which I put temporarily in a nested StackPanel) should be on the right side.

I tried already lots of combinations of alignments but I cannot get the label on the right side.
What should I add to accomplish this?



Aligning controls on both left and right side in a stack panel in WPF

I am currently writing a desktop application, but I cannot seem to get my head around what to use when redirecting someone to a new section of the application.

My options appear to be

* Window
* Page
* UserControl

but I don&#39;t understand what the difference between them is, and when I should use each one.

Could someone explain the differences for me, and give an example of what situations/applications you may use each one for?

Window vs Page vs UserControl for WPF navigation?

I have a view `AttributeView` that contains all sorts of attributes. There&#39;s also a button that when pressed, it should set the default values to the attributes. I also have a `ViewModelBase` class that is a base class for all ViewModels I have.
The problem is I can&#39;t seem to get the button bound to the command with WPF.

I&#39;ve tried this, but it just doesn&#39;t do anything:

    &lt;Button Command=&quot;{Binding DataInitialization}&quot; Content=&quot;{x:Static localProperties:Resources.BtnReinitializeData}&quot;&gt;&lt;/Button&gt;

The command is defined (in the `ViewModelBase`) like this:

    public CommandBase DataInitialization { get; protected set; }

and on application startup a new instance is created for the command:

    DataInitialization = new DataInitializationCommand()

However, the WPF binding doesn&#39;t seem to &quot;find&quot; the command (pressing the button does nothing). The ViewModel used in the current view is derived from the `ViewModelBase`. What else I can try (I&#39;m quite new to WPF so this might be a very simple question)?

How to bind WPF button to a command in ViewModelBase?

Here is an example of what I want to do:
```cs
MessageBox.Show(&quot;Error line number &quot; + CurrentLineNumber);
```
In the code above the `CurrentLineNumber`, should be the line number in the source code of this piece of code.

How can I do that?

How do I get the current line number?

The JSF [`&lt;h:outputStylesheet&gt;`][1], [`&lt;h:outputScript&gt;`][2] and [`&lt;h:graphicImage&gt;`][3] components have a `library` attribute. What is this and how should this be used? There are a lot of examples on the web which use it as follows with the common content/file type `css`, `js` and `img` (or `image`) as library name depending on the tag used:

&lt;!-- language: xhtml --&gt;

    &lt;h:outputStylesheet library=&quot;css&quot; name=&quot;style.css&quot; /&gt;
    &lt;h:outputScript library=&quot;js&quot; name=&quot;script.js&quot; /&gt;
    &lt;h:graphicImage library=&quot;img&quot; name=&quot;logo.png&quot; /&gt;

How is it useful? The `library` value in those examples seems to be just repeating whatever is already been represented by the tag name. For a `&lt;h:outputStylesheet&gt;` it&#39;s based on the tag name already obvious that it represents a &quot;CSS library&quot;. What&#39;s the difference with the following which also just works the same way?

&lt;!-- language: xhtml --&gt;

    &lt;h:outputStylesheet name=&quot;css/style.css&quot; /&gt;
    &lt;h:outputScript name=&quot;js/script.js&quot; /&gt;
    &lt;h:graphicImage name=&quot;img/logo.png&quot; /&gt;

Also, the generated HTML output is a bit different. Given a context path of `/contextname` and `FacesServlet` mapping on an URL pattern of `*.xhtml`, the former generates the following HTML with the library name as request parameter:

&lt;!-- language: xhtml --&gt;

    &lt;link rel=&quot;stylesheet&quot; type=&quot;text/css&quot; href=&quot;/contextname/javax.faces.resource/style.css.xhtml?ln=css&quot; /&gt;
    &lt;script type=&quot;text/javascript&quot; src=&quot;/contextname/javax.faces.resource/script.js.xhtml?ln=js&quot;&gt;&lt;/script&gt;
    &lt;img src=&quot;/contextname/javax.faces.resource/logo.png.xhtml?ln=img&quot; alt=&quot;&quot; /&gt;

While the latter generates the following HTML with the library name just in the path of the URI:

&lt;!-- language: xhtml --&gt;

    &lt;link rel=&quot;stylesheet&quot; type=&quot;text/css&quot; href=&quot;/contextname/javax.faces.resource/css/style.css.xhtml&quot; /&gt;
    &lt;script type=&quot;text/javascript&quot; src=&quot;/contextname/javax.faces.resource/js/script.js.xhtml&quot;&gt;&lt;/script&gt;
    &lt;img src=&quot;/contextname/javax.faces.resource/img/logo.png.xhtml&quot; alt=&quot;&quot; /&gt;

The latter approach makes in hindsight also more sense than the former approach. How exactly is the `library` attribute then useful?

Why does Eclipse give me the warming &quot;Resource leak: &#39;in&#39; is never closed&quot; in the following code?

    public void readShapeData() {
            Scanner in = new Scanner(System.in);
            System.out.println(&quot;Enter the width of the Rectangle: &quot;);
            width = in.nextDouble();
            System.out.println(&quot;Enter the height of the Rectangle: &quot;);
            height = in.nextDouble();

What&#39;s the difference between two asterisks instead of one asterisk when we refer to paths?

Earlier I was debugging my Spring 3 project. I was trying to add a .swf using

`&lt;spring:url var=&quot;flashy&quot; value=&quot;/resources/images/flash.swf&quot;/&gt;`

With my web.xml&#39;s ResourceServlet looking like

    &lt;servlet-name&gt;Resource Servlet &lt;/servlet-name&gt;
    &lt;url-pattern&gt;/resources/*&lt;/url-pattern&gt;

But unfortunately I was getting this error: 

`WARN org.springframework.js.resources.ResourceServlet - An attempt to access a protected resource at /images/flash.swf was disallowed.`

I found it really strange since all my images in the `images` folder were accessed but how come my  .swf was &quot;protected&quot;?

Afterwards, I decided to change the `/resources/*` to `/resources/**` and it finally worked. My question is... why?

Spring: Difference of /** and /* with regards to paths

I want to open a file from the folder **res/raw/**. 
I am absolutely sure that the file exists.
To open the file I have tried

    File ddd = new File(&quot;res/raw/example.png&quot;);

The command 

    ddd.exists(); 

yields **FALSE**. So this method does not work.

Trying

    MyContext.getAssets().open(&quot;example.png&quot;);

**ends up in an exception with getMessage() &quot;null&quot;.**

Simply using 

    R.raw.example

is not possible because the filename is only known during runtime as a string.

Why is it so difficult to access a file in the folder /res/raw/ ?

How to read file from res/raw by name

I&#39;m loading a text file from within a package in a compiled JAR of my Java project. The relevant directory structure is as follows:

    /src/initialization/Lifepaths.txt

My code loads a file by calling [`Class::getResourceAsStream`][1] to return a [`InputStream`][2]. 

    public class Lifepaths {
        public static void execute() {
            System.out.println(Lifepaths.class.getClass().
                getResourceAsStream(&quot;/initialization/Lifepaths.txt&quot;));
        }

        private Lifepaths() {}

        //This is temporary; will eventually be called from outside
        public static void main(String[] args) {execute();}
    }

The print out will always print `null`, no matter what I use. I&#39;m not sure why the above wouldn&#39;t work, so I&#39;ve also tried:

 - `&quot;/src/initialization/Lifepaths.txt&quot;`
 - `&quot;initialization/Lifepaths.txt&quot;`
 - `&quot;Lifepaths.txt&quot;`

Neither of these work. [I&#39;ve](https://stackoverflow.com/questions/12262062/getresourceasstream-returns-null) [read](https://stackoverflow.com/questions/7017361/getresourceasstream-returning-null) [numerous](https://stackoverflow.com/questions/2797162/getresourceasstream-is-always-returning-null) [questions](https://stackoverflow.com/questions/2195445/eclipse-getresourceasstream-returning-null) so far on the topic, but none of them have been helpful - usually, they just say to load files using the root path, which I&#39;m already doing. That, or just load the file from the current directory (just load `filename`), which I&#39;ve also tried. The file is being compiled into the JAR in the appropriate location with the appropriate name. 

How do I solve this?
