For Kotlin

What will you get:

Gray color if the hint is selected

Drop down list with gray color of the hint

Black color if something else than the hint is selected

I have added 5. step what changes the color of the text in the spinner depending on the selected item, because I couldn't find it here. In this case it is needed to change the text color to gray when the first item is selected in order to it looks like a hint.

1. Define a spinner in your activity_layout.xml

   <Spinner
       android:id="@+id/mySpinner"
       android:layout_width="match_parent"
       android:layout_height="wrap_content" />
   

2. Define the string array in string.xml where the first item will be a hint.

   <string-array name="your_string_array">
       <item>Hint...</item>
       <item>Item1</item>
       <item>Item2</item>
       <item>Item3</item>
   </string-array>
   

3. Set up the spinner in the onCreate method in your Activity.kt

   Get string array from resources

       val items= resources.getStringArray(R.array.your_string_array)
   

   Create spinner adapter

       val spinnerAdapter= object : ArrayAdapter<String>(this,android.R.layout.simple_spinner_item, items) {
   
       override fun isEnabled(position: Int): Boolean {
           // Disable the first item from Spinner
           // First item will be use for hint
           return position != 0
       }
   
       override fun getDropDownView(
           position: Int,
           convertView: View?,
           parent: ViewGroup
       ): View {
           val view: TextView = super.getDropDownView(position, convertView, parent) as TextView
           //set the color of first item in the drop down list to gray
           if(position == 0) {
               view.setTextColor(Color.GRAY)
           } else {
               //here is it possible to define color for other items by
               //view.setTextColor(Color.RED)
           }
           return view
       }
   
   }
   

4. Set drop down view resource and attach the adapter to your spinner.

   spinnerAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item)     
   mySpinner.adapter = spinnerAdapter
   

5. Change the color of the text in the spinner depending on the selected item

   mySpinner.onItemSelectedListener = object: AdapterView.OnItemSelectedListener{
       override fun onNothingSelected(parent: AdapterView<*>?) {
       }
   
       override fun onItemSelected(
           parent: AdapterView<*>?,
           view: View?,
           position: Int,
           id: Long
       ) {
           val value = parent!!.getItemAtPosition(position).toString()
           if(value == items[0]){
               (view as TextView).setTextColor(Color.GRAY)
           }
       }
   
   }
   

Compare string with value from index

private void selectSpinnerValue(Spinner spinner, String myString)
     {
         int index = 0;
         for(int i = 0; i < spinner.getCount(); i++){
             if(spinner.getItemAtPosition(i).toString().equals(myString)){
                 spinner.setSelection(i);
                 break;
             }
         }
     }

The customized spinner posted by @Menol had a small issue where the spinner would be shifted down and to the right by the size of one dot. I have updated the code so that it compensates for this offset by subtracting by half the dot.

Here is the updated code:

    private void initialSetup()
    {
        float horizontalCenter = (float)(SpinnerWidth / 2);
        float verticalCenter = (float)(SpinnerHeight / 2);
        float distance = (float)Math.Min(SpinnerHeight, SpinnerWidth) / 2;
        float dotComp = (float)(EllipseSize / 2);

        double angleInRadians = 44.8;
        float cosine = (float)Math.Cos(angleInRadians);
        float sine = (float)Math.Sin(angleInRadians);

        EllipseN = newPos(left: horizontalCenter - dotComp, top: verticalCenter - distance - dotComp);
        EllipseNE = newPos(left: horizontalCenter + (distance * cosine) - dotComp, top: verticalCenter - (distance * sine) - dotComp);
        EllipseE = newPos(left: horizontalCenter + distance - dotComp, top: verticalCenter - dotComp);
        EllipseSE = newPos(left: horizontalCenter + (distance * cosine) - dotComp, top: verticalCenter + (distance * sine) - dotComp);
        EllipseS = newPos(left: horizontalCenter - dotComp, top: verticalCenter + distance - dotComp);
        EllipseSW = newPos(left: horizontalCenter - (distance * cosine) - dotComp, top: verticalCenter + (distance * sine) - dotComp);
        EllipseW = newPos(left: horizontalCenter - distance - dotComp, top: verticalCenter - dotComp);
        EllipseNW = newPos(left: horizontalCenter - (distance * cosine) - dotComp, top: verticalCenter - (distance * sine) - dotComp);
    }

add setOnItemSelectedListener to spinner reference and get the data like that`

 mSizeSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> adapterView, View view, int position, long l) {
            selectedSize=adapterView.getItemAtPosition(position).toString();

XML file:

<Spinner
    android:id="@+id/Spinner01"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"/>

Java file:

public class SpinnerExample extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        String[] arraySpinner = new String[] {
            "1", "2", "3", "4", "5", "6", "7"
        };
        Spinner s = (Spinner) findViewById(R.id.Spinner01);
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                android.R.layout.simple_spinner_item, arraySpinner);
        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        s.setAdapter(adapter);
    }
}

See spinner example.

To get the selected value of a spinner you can follow this example.

Create a nested class that implements AdapterView.OnItemSelectedListener. This will provide a callback method that will notify your application when an item has been selected from the Spinner.

Within "onItemSelected" method of that class, you can get the selected item:

public class YourItemSelectedListener implements OnItemSelectedListener {

    public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
        String selected = parent.getItemAtPosition(pos).toString();
    }

    public void onNothingSelected(AdapterView parent) {
        // Do nothing.
    }
}

Finally, your ItemSelectedListener needs to be registered in the Spinner:

spinner.setOnItemSelectedListener(new MyOnItemSelectedListener());

Spinner sp = (Spinner)findViewById(R.id.spinner); 
sp.setSelection(pos);

here pos is integer (your array item position)

array is like below then pos = 0;

String str[] = new String{"Select Gender","male", "female" };

then in onItemSelected

@Override
    public void onItemSelected(AdapterView<?> main, View view, int position,
            long Id) {

        if(position > 0){
          // get spinner value
        }else{
          // show toast select gender
        }

    }

You can make a generic method for this kind of work as I do in my UtilityClass which is

public void SetSpinnerSelection(Spinner spinner,String[] array,String text) {
    for(int i=0;i<array.length;i++) {
        if(array[i].equals(text)) {
            spinner.setSelection(i);
        }
    }
}

MODE_DIALOG and MODE_DROPDOWN are defined in API 11 (Honeycomb). MODE_DIALOG describes the usual behaviour in previous platform versions.

Here is a link that can help you to change the color of the Spinner:

Click here

<Spinner
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:id="@+id/spinner"
    android:textSize="20sp"
    android:entries="@array/planets"/>

You need to create your own layout file with a custom definition for the spinner item spinner_item.xml:

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/text1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:textSize="20sp"
    android:textColor="#ff0000" />

If you want to customize the dropdown list items, you will need to create a new layout file. spinner_dropdown_item.xml:

<?xml version="1.0" encoding="utf-8"?>
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/text1"
    style="?android:attr/spinnerDropDownItemStyle"
    android:maxLines="1"
    android:layout_width="match_parent"
    android:layout_height="?android:attr/listPreferredItemHeight"
    android:ellipsize="marquee"
    android:textColor="#aa66cc"/>

And finally another change in the declaration of the spinner:

ArrayAdapter adapter = ArrayAdapter.createFromResource(this,
R.array.planets_array, R.layout.spinner_item);

adapter.setDropDownViewResource(R.layout.spinner_dropdown_item);
spinner.setAdapter(adapter);

That's it.

My solution uses onTouchListener but doesn't restricts from its use. It creates a wrapper for onTouchListener if necessary where setup onItemSelectedListener.

public class Spinner extends android.widget.Spinner {
    /* ...constructors... */

    private OnTouchListener onTouchListener;
    private OnItemSelectedListener onItemSelectedListener;

    @Override
    public void setOnItemSelectedListener(OnItemSelectedListener listener) {
        onItemSelectedListener = listener;
        super.setOnTouchListener(wrapTouchListener(onTouchListener, onItemSelectedListener));
    }

    @Override
    public void setOnTouchListener(OnTouchListener listener) {
        onTouchListener = listener;
        super.setOnTouchListener(wrapTouchListener(onTouchListener, onItemSelectedListener));
    }

    private OnTouchListener wrapTouchListener(final OnTouchListener onTouchListener, final OnItemSelectedListener onItemSelectedListener) {
        return onItemSelectedListener != null ? new OnTouchListener() {
            @Override
            public boolean onTouch(View view, MotionEvent motionEvent) {
                Spinner.super.setOnItemSelectedListener(onItemSelectedListener);
                return onTouchListener != null && onTouchListener.onTouch(view, motionEvent);
            }
        } : onTouchListener;
    }
}

First of all, a spinner does not support item click events. Calling this method will raise an exception.

You can use setOnItemSelectedListener:

Spinner s1;
s1 = (Spinner)findViewById(R.id.s1);
int selectionCurrent = s1.getSelectedItemPosition();

spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
            if (selectionCurrent != position){
                // Your code here
            }
            selectionCurrent= position;
        }
    }

    @Override
    public void onNothingSelected(AdapterView<?> parentView) {
        // Your code here
    }
});

For simple solutions you can just Overwrite the "toString" in your object

public class User{
    public int ID;
    public String name;

    @Override
    public String toString() {
        return name;
    }
}

and then you can use:

ArrayAdapter<User> dataAdapter = new ArrayAdapter<User>(mContext, android.R.layout.simple_spinner_item, listOfUsers);

This way your spinner will show only the user names.

spinner.setOnItemSelectedListener(
            new AdapterView.OnItemSelectedListener() {

                @Override
                public void onItemSelected(AdapterView<?> arg0, View arg1,
                        int arg2, long arg3) {

                    // TODO Auto-generated method stub
                }

                @Override
                public void onNothingSelected(AdapterView<?> arg0) {
                    // TODO Auto-generated method stub

                }
                //add some code here
            }
        );

A control that is missing from the original set of WPF controls, but much used, is the NumericUpDown control. It is a neat way to get users to select a number from a fixed range, in a small area. A slider could be used, but for compact forms with little horizontal real-estate, the NumericUpDown is essential.

Solution A (via WindowsFormsHost)

You can use the Windows Forms NumericUpDown control in WPF by hosting it in a WindowsFormsHost. Pay attention that you have to include a reference to System.Windows.Forms.dll assembly.

<Window x:Class="WpfApplication61.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:wf="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms" 
        Title="MainWindow" Height="350" Width="525">
    <StackPanel>    
        <WindowsFormsHost>
            <wf:NumericUpDown/>
        </WindowsFormsHost>
...

Solution B (custom)

There are several commercial and codeplex versions around, but both involve installing 3rd party dlls and overheads to your project. Far simpler to build your own, and a aimple way to do that is with the ScrollBar.

A vertical ScrollBar with no Thumb (just the repeater buttons) is in fact just what we want. It inherits rom RangeBase, so it has all the properties we need, like Min, Max, and SmallChange (set to 1, to restrict it to Integer values)

So we change the ScrollBar ControlTemplate. First we remove the Thumb and Horizontal trigger actions. Then we group the remains into a grid and add a TextBlock for the number:

<Grid Margin="2">
    <Grid.ColumnDefinitions>
        <ColumnDefinition/>
        <ColumnDefinition />
    </Grid.ColumnDefinitions>
    <TextBlock VerticalAlignment="Center" FontSize="20" MinWidth="25" Text="{Binding Value, RelativeSource={RelativeSource TemplatedParent}}"/>
    <Grid Grid.Column="1" x:Name="GridRoot" Width="{DynamicResource {x:Static SystemParameters.VerticalScrollBarWidthKey}}" Background="{TemplateBinding Background}">
        <Grid.RowDefinitions>
            <RowDefinition MaxHeight="18"/>
            <RowDefinition Height="0.00001*"/>
            <RowDefinition MaxHeight="18"/>
        </Grid.RowDefinitions>
        <RepeatButton x:Name="DecreaseRepeat" Command="ScrollBar.LineDownCommand" Focusable="False">
            <Grid>
                <Path x:Name="DecreaseArrow" Stroke="{TemplateBinding Foreground}" StrokeThickness="1" Data="M 0 4 L 8 4 L 4 0 Z"/>
            </Grid>
        </RepeatButton>
        <RepeatButton Grid.Row="2" x:Name="IncreaseRepeat" Command="ScrollBar.LineUpCommand" Focusable="False">
            <Grid>
                <Path x:Name="IncreaseArrow" Stroke="{TemplateBinding Foreground}" StrokeThickness="1" Data="M 0 0 L 4 4 L 8 0 Z"/>
            </Grid>
        </RepeatButton>
    </Grid>
</Grid>

It's worth pointing out that the default value of -moz-appearance on these elements is number-input in Firefox.

If you want to hide the spinner by default, you can set -moz-appearance: textfield initially, and if you want the spinner to appear on :hover/:focus, you can overwrite the previous styling with -moz-appearance: number-input.

input[type="number"] {_x000D_
    -moz-appearance: textfield;_x000D_
}_x000D_
input[type="number"]:hover,_x000D_
input[type="number"]:focus {_x000D_
    -moz-appearance: number-input;_x000D_
}

<input type="number"/>

I thought someone might find that helpful since I recently had to do this in attempts to improve consistency between Chrome/FF (since this is the way number inputs behave by default in Chrome).

If you want to see all the available values for -moz-appearance, you can find them here (mdn).

If you need to have an indexOf method on any old Adapter (and you don't know the underlying implementation) then you can use this:

private int indexOf(final Adapter adapter, Object value)
{
    for (int index = 0, count = adapter.getCount(); index < count; ++index)
    {
        if (adapter.getItem(index).equals(value))
        {
            return index;
        }
    }
    return -1;
}

this work for me:-

String[] array = {"A", "B", "C"};
String abc = "";


Spinner spinner = new Spinner(getContext());
ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(getContext(), android.R.layout.simple_spinner_item, array); //selected item will look like a spinner set from XML
spinnerArrayAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(spinnerArrayAdapter);

I am using a Fragment.

For Kotlin and bindings the code is:

binding.spinner.onItemSelectedListener = object : AdapterView.OnItemSelectedListener{
            override fun onNothingSelected(parent: AdapterView<*>?) {
            }

            override fun onItemSelected(parent: AdapterView<*>?, view: View?, position: Int, id: Long) {
            }
        }

Use the cmd.exe command processor to build a timestamped file name to log your scheduled task's output

To build upon answers by others here, it may be that you want to create an output file that has the date and/or time embedded in the name of the file. You can use the cmd.exe command processor to do this for you.

Note: This technique takes the string output of internal Windows environment variables and slices them up based on character position. Because of this, the exact values supplied in the examples below may not be correct for the region of Windows you use. Also, with some regional settings, some components of the date or time may introduce a space into the constructed file name when their value is less than 10. To mitigate this issue, surround your file name with quotes so that any unintended spaces in the file name won't break the command-line you're constructing. Experiment and find what works best for your situation.

Be aware that PowerShell is more powerful than cmd.exe. One way it is more powerful is that it can deal with different Windows regions. But this answer is about solving this issue using cmd.exe, not PowerShell, so we continue.

Using cmd.exe

You can access different components of the date and time by slicing the internal environment variables %date% and %time%, as follows (again, the exact slicing values are dependent on the region configured in Windows):

• Year (4 digits): %date:~10,4%
• Month (2 digits): %date:~4,2%
• Day (2 digits): %date:~7,2%
• Hour (2 digits): %time:~0,2%
• Minute (2 digits): %time:~3,2%
• Second (2 digits): %time:~6,2%

Suppose you want your log file to be named using this date/time format: "Log_[yyyyMMdd]_[hhmmss].txt". You'd use the following:

Log_%date:~10,4%%date:~4,2%%date:~7,2%_%time:~0,2%%time:~3,2%%time:~6,2%.txt

To test this, run the following command line:

cmd.exe /c echo "Log_%date:~10,4%%date:~4,2%%date:~7,2%_%time:~0,2%%time:~3,2%%time:~6,2%.txt"

Putting it all together, to redirect both stdout and stderr from your script to a log file named with the current date and time, use might use the following as your command line:

cmd /c YourProgram.cmd > "Log_%date:~10,4%%date:~4,2%%date:~7,2%_%time:~0,2%%time:~3,2%%time:~6,2%.txt" 2>&1

Note the use of quotes around the file name to handle instances a date or time component may introduce a space character.

In my case, if the current date/time were 10/05/2017 9:05:34 AM, the above command-line would produce the following:

cmd /c YourProgram.cmd > "Log_20171005_ 90534.txt" 2>&1

You can also extend FloatingPoint in Swift 3 as follow:

extension FloatingPoint {
    func rounded(to n: Int) -> Self {
        let n = Self(n)
        return (self / n).rounded() * n

    }
}

324.0.rounded(to: 5)   // 325

Update PHP 7.4

Curly brace access syntax is deprecated since PHP 7.4

Update 2019

Moving on to the best practices of OOPS, @MrTrick's answer must be marked as correct, although my answer provides a hacked solution its not the best method.

Simply iterate its using {}

Example:

$videos{0}->id

This way your object is not destroyed and you can easily iterate through object.

For PHP 5.6 and below use this

$videos{0}['id']

Both array() and the stdClass objects can be accessed using the current() key() next() prev() reset() end() functions.

So, if your object looks like

object(stdClass)#19 (3) {
  [0]=>
  object(stdClass)#20 (22) {
    ["id"]=>
    string(1) "123"
  etc...

Then you can just do;

$id = reset($obj)->id; //Gets the 'id' attr of the first entry in the object

If you need the key for some reason, you can do;

reset($obj); //Ensure that we're at the first element
$key = key($obj);

Hope that works for you. :-) No errors, even in super-strict mode, on PHP 5.4

2022 Update:
After PHP 7.4, using current(), end(), etc functions on objects is deprecated.

In newer versions of PHP, use the ArrayIterator class:

$objIterator = new ArrayIterator($obj);

$id = $objIterator->current()->id; // Gets the 'id' attr of the first entry in the object

$key = $objIterator->key(); // and gets the key

If you check Thrown for Common Language Runtime Exception in the break when an exception window (Ctrl+Alt+E in Visual Studio), then the execution should break while you are debugging when the exception is thrown.

This will probably give you some insight into what is going on.

Use both @Deprecated annotation and the @deprecated JavaDoc tag.

The @deprecated JavaDoc tag is used for documentation purposes.

The @Deprecated annotation instructs the compiler that the method is deprecated. Here is what it says in Sun/Oracles document on the subject:

Using the @Deprecated annotation to deprecate a class, method, or field ensures that all compilers will issue warnings when code uses that program element. In contrast, there is no guarantee that all compilers will always issue warnings based on the @deprecated Javadoc tag, though the Sun compilers currently do so. Other compilers may not issue such warnings. Thus, using the @Deprecated annotation to generate warnings is more portable that relying on the @deprecated Javadoc tag.

You can find the full document at How and When to Deprecate APIs

You can only change the language on the whole server, not individual databases. However if you need to support the UK you can run the following command before all inputs and outputs:

set language 'british english'

Or if you are having issues entering datatimes from your application you might want to consider a universal input type such as

1-Dec-2008

I found solution. It works fine when I throw away next line from form:

enctype="multipart/form-data"

And now it pass all parameters at request ok:

 <form action="/registration" method="post">
   <%-- error messages --%>
   <div class="form-group">
    <c:forEach items="${registrationErrors}" var="error">
    <p class="error">${error}</p>
     </c:forEach>
   </div>

not sure if it'll work in your scenario, but try adding the following to your web.config under <system.web>:

  <system.web>
    <customErrors mode="Off" />
  ...
  </system.web>

works in my instance.

also see:

CustomErrors mode="Off"

Let me add an example here:

I'm trying to build Alluxio on windows platform and got the same issue, it's because the pom.xml contains below step:

      <plugin>
        <artifactId>exec-maven-plugin</artifactId>
        <groupId>org.codehaus.mojo</groupId>
        <inherited>false</inherited>
        <executions>
          <execution>
            <id>Check that there are no Windows line endings</id>
            <phase>compile</phase>
            <goals>
              <goal>exec</goal>
            </goals>
            <configuration>
              <executable>${build.path}/style/check_no_windows_line_endings.sh</executable>
            </configuration>
          </execution>
        </executions>
      </plugin>

The .sh file is not executable on windows so the error throws.

Comment it out if you do want build Alluxio on windows.

Your problem comes from the 32/64 bit version of your JDK/JRE... Your shared lib is searched for a 32 bit version.

Your default JDK is a 32 bit version. Try to install a 64 bit one by default and relaunch your `.sh file.

A little late to the game, but I've written a class setlist as part of collections-extended that fully implements both Sequence and Set

>>> from collections_extended import setlist
>>> sl = setlist('abracadabra')
>>> sl
setlist(('a', 'b', 'r', 'c', 'd'))
>>> sl[3]
'c'
>>> sl[-1]
'd'
>>> 'r' in sl  # testing for inclusion is fast
True
>>> sl.index('d')  # so is finding the index of an element
4
>>> sl.insert(1, 'd')  # inserting an element already in raises a ValueError
ValueError
>>> sl.index('d')
4

in my guess, the rightest man who suggested normal variant is GigolNet Gigolashvili, but i wanna suggest even more beautiful variant. Check it

$(document).on('click', '.fieldWrapper > label', function(event) {
    event.preventDefault()
    var n = $( event.target ).parent().find('input:checked').length
    var m = $( event.target ).parent().find('input').length
    x = n==m? false:true
    $( event.target ).parent().find('input').each(function (ind, el) {
        // $(el).attr('checked', 'checked');
        this.checked = x
    })
})

The general format, from the @link section of the javadoc documentation, is:

Examples

Method in the same class:

/** See also {@link #myMethod(String)}. */
void foo() { ... }

Method in a different class, either in the same package or imported:

/** See also {@link MyOtherClass#myMethod(String)}. */
void foo() { ... }

Method in a different package and not imported:

/** See also {@link com.mypackage.YetAnotherClass#myMethod(String)}. */
void foo() { ... }

Label linked to method, in plain text rather than code font:

/** See also this {@linkplain #myMethod(String) implementation}. */
void foo() { ... }

A chain of method calls, as in your question. We have to specify labels for the links to methods outside this class, or we get getFoo().Foo.getBar().Bar.getBaz(). But these labels can be fragile during refactoring -- see "Labels" below.

/**
 * A convenience method, equivalent to 
 * {@link #getFoo()}.{@link Foo#getBar() getBar()}.{@link Bar#getBaz() getBaz()}.
 * @return baz
 */
public Baz fooBarBaz()

Labels

Automated refactoring may not affect labels. This includes renaming the method, class or package; and changing the method signature.

Therefore, provide a label only if you want different text than the default.

For example, you might link from human language to code:

/** You can also {@linkplain #getFoo() get the current foo}. */
void setFoo( Foo foo ) { ... }

Or you might link from a code sample with text different than the default, as shown above under "A chain of method calls." However, this can be fragile while APIs are evolving.

Type erasure and #member

If the method signature includes parameterized types, use the erasure of those types in the javadoc @link. For example:

int bar( Collection<Integer> receiver ) { ... }

/** See also {@link #bar(Collection)}. */
void foo() { ... }

You can find your Firebase Web API Key in the follwing way .

The trim() method removes whitespace from both sides of a string.

To remove all the spaces from the string use .replace(/\s/g, "")

 this.maintabinfo = this.inner_view_data.replace(/\s/g, "").toLowerCase();

In C# it is not possible to call another constructor from inside the method body. You can call a base constructor this way: foo(args):base() as pointed out yourself. You can also call another constructor in the same class: foo(args):this().

When you want to do something before calling a base constructor, it seems the construction of the base is class is dependant of some external things. If so, you should through arguments of the base constructor, not by setting properties of the base class or something like that

Application.Exit is for Windows Forms applications - it informs all message pumps that they should terminate, waits for them to finish processing events and then terminates the application. Note that it doesn't necessarily force the application to exit.

Environment.Exit is applicable for all Windows applications, however it is mainly intended for use in console applications. It immediately terminates the process with the given exit code.

In general you should use Application.Exit in Windows Forms applications and Environment.Exit in console applications, (although I prefer to let the Main method / entry point run to completion rather than call Environment.Exit in console applications).

For more detail see the MSDN documentation.

If you want to permanently ignore these files, a simple way to add them to .gitignore is:

1. Change to the root of the git tree.
2. git ls-files --others --exclude-standard >> .gitignore

This will enumerate all files inside untracked directories, which may or may not be what you want.

 Assembly assembly = Assembly.LoadFile(@"....bin\Debug\TestCases.dll");
       //get all types
        var testTypes = from t in assembly.GetTypes()
                        let attributes = t.GetCustomAttributes(typeof(NUnit.Framework.TestFixtureAttribute), true)
                        where attributes != null && attributes.Length > 0
                        orderby t.Name
                        select t;

        foreach (var type in testTypes)
        {
            //get test method in types.
            var testMethods = from m in type.GetMethods()

                              select m;

            foreach (var method in testMethods)
            {
                MethodInfo methodInfo = type.GetMethod(method.Name);

                if (methodInfo != null)
                {
                    object result = null;
                    ParameterInfo[] parameters = methodInfo.GetParameters();
                    object classInstance = Activator.CreateInstance(type, null);

                    if (parameters.Length == 0)
                    {
                        // This works fine
                        result = methodInfo.Invoke(classInstance, null);
                    }
                    else
                    {
                        object[] parametersArray = new object[] { "Hello" };

                        // The invoke does NOT work;
                        // it throws "Object does not match target type"             
                        result = methodInfo.Invoke(classInstance, parametersArray);
                    }
                }

            }
        }

I found the generated set of drop statements useful, and recommend these tweaks:

1. Limit the generated drops to your database like this:

SELECT concat('DROP TABLE IF EXISTS `', table_name, '`;')
FROM information_schema.tables
WHERE table_schema = 'MyDatabaseName';

Note 1: This does not execute the DROP statements, it just gives you a list of them. You will need to cut and paste the output into your SQL engine to execute them.

Note 2: If you have VIEWs, you'll have to correct each DROP TABLE `VIEW_NAME` statement to DROP VIEW `VIEW_NAME` manually.

2. Note, per http://dev.mysql.com/doc/refman/5.5/en/drop-table.html, dropping with cascade is pointless / misleading:

"RESTRICT and CASCADE are permitted to make porting easier. In MySQL 5.5, they do nothing."

Therefore, in order for the drop statements to work if you need:

SET FOREIGN_KEY_CHECKS = 0

This will disable referential integrity checks - so when you are done performing the drops you need, you will want to reset key checking with

SET FOREIGN_KEY_CHECKS = 1

3. The final execution should look like:

SET FOREIGN_KEY_CHECKS = 0;
-- Your semicolon separated list of DROP statements here
SET FOREIGN_KEY_CHECKS = 1;

NB: to use output of SELECT easier, mysql -B option can help.

You can convert the value to a date using a formula like this, next to the cell:

=DATE(LEFT(A1,4),MID(A1,5,2),RIGHT(A1,2))

Where A1 is the field you need to convert.

Alternatively, you could use this code in VBA:

Sub ConvertYYYYMMDDToDate()
   Dim c As Range
   For Each c In Selection.Cells
       c.Value = DateSerial(Left(c.Value, 4), Mid(c.Value, 5, 2), Right(c.Value, 2))
       'Following line added only to enforce the format.
       c.NumberFormat = "mm/dd/yyyy"
   Next
End Sub

Just highlight any cells you want fixed and run the code.

Note as RJohnson mentioned in the comments, this code will error if one of your selected cells is empty. You can add a condition on c.value to skip the update if it is blank.

Git 1.8.2 features a new option ,--remote, that will enable exactly this behavior. Running

git submodule update --rebase --remote

will fetch the latest changes from upstream in each submodule, rebase them, and check out the latest revision of the submodule. As the documentation puts it:

--remote

This option is only valid for the update command. Instead of using the superproject’s recorded SHA-1 to update the submodule, use the status of the submodule’s remote-tracking branch.

This is equivalent to running git pull in each submodule, which is generally exactly what you want.

You could use inline styles and define the width in the <th> tag. Make it so that the sum of the widths = 100%.

    <tr>
        <th style="width:10%">Size</th>
        <th style="width:30%">Bust</th>
        <th style="width:50%">Waist</th>
        <th style="width:10%">Hips</th>
    </tr>

Bootply demo

Typically using inline styles is not ideal, however this does provide flexibility because you can get very specific and granular with exact widths.

States transitioning from one commit to new commit

0. last commit,i.e. HEAD commit
1. Working tree changes, file/directory deletion,adding,modification.
2. The changes are staged in index
3. Staged changes are committed

Action for state transitioning

0->1: manual file/directory operation
1->2: git add .
2->3: git commit -m "xxx"

Check diff

0->1: git diff
0->2: git diff --cached
0->1, and 0->2: git diff HEAD
last last commit->last commit: git diff HEAD^ HEAD

Revert to last commit

2->1: git reset
1->0: git checkout .     #only for tracked files/directories(actions include modifying/deleting tracked files/directories)
1->0: git clean -fdx     #only for untracked files/directories(action includes adding new files/directories)
2->1, and 1->0: git reset --hard HEAD

Equivalent of git clone, without re-downloading anything

git reset && git checkout . && git clean -fdx

I use a Dictionary and because of the repetetiveness and possible missing keys, I quickly patched together a small method:

 private static string GetKey(IReadOnlyDictionary<string, string> dictValues, string keyValue)
 {
     return dictValues.ContainsKey(keyValue) ? dictValues[keyValue] : "";
 }

Calling it:

var entry = GetKey(dictList,"KeyValue1");

Gets the job done.

A complex filter condition is better in performance perspective, but the best performance will show old fashion for loop with a standard if clause is the best option. The difference on a small array 10 elements difference might ~ 2 times, for a large array the difference is not that big.
You can take a look on my GitHub project, where I did performance tests for multiple array iteration options

For small array 10 element throughput ops/s: For medium 10,000 elements throughput ops/s: For large array 1,000,000 elements throughput ops/s:

NOTE: tests runs on

• java version: 1.8.0_121
• jvm: -XX:+UseG1GC -server -Xmx1024m -Xms1024m

UPDATE: Java 11 has some progress on the performance, but the dynamics stay the same

Benchmark mode: Throughput, ops/time

Without dropdown ID:

I think part of it is that you're stating the value you're selecting after CASE, and then using WHEN x = y syntax afterward, which is a combination of two different methods of using CASE. It should either be

CASE X
  WHEN a THEN ...
  WHEN b THEN ...

or

CASE
  WHEN x = a THEN ...
  WHEN x = b THEN ...

A possibility is that the element is currently unclickable because it is not visible. Reasons for this may be that another element is covering it up or it is not in view, i.e. it is outside the currently view-able area.

Try this

from selenium.webdriver.common.action_chains import ActionChains

button = driver.find_element_by_class_name(u"infoDismiss")
driver.implicitly_wait(10)
ActionChains(driver).move_to_element(button).click(button).perform()

If I recall correctly Twig doesn't support || and && operators, but requires or and and to be used respectively. I'd also use parentheses to denote the two statements more clearly although this isn't technically a requirement.

{%if ( fields | length > 0 ) or ( trans_fields | length > 0 ) %}

Expressions

Expressions can be used in {% blocks %} and ${ expressions }.

Operator    Description
==          Does the left expression equal the right expression?
+           Convert both arguments into a number and add them.
-           Convert both arguments into a number and substract them.
*           Convert both arguments into a number and multiply them.
/           Convert both arguments into a number and divide them.
%           Convert both arguments into a number and calculate the rest of the integer division.
~           Convert both arguments into a string and concatenate them.
or          True if the left or the right expression is true.
and         True if the left and the right expression is true.
not         Negate the expression.

For more complex operations, it may be best to wrap individual expressions in parentheses to avoid confusion:

{% if (foo and bar) or (fizz and (foo + bar == 3)) %}

Change this line:

The 2 should be 0. Every count starts at 0.

//Aboutme.Text = String.Format("{2}", reader.GetString(0));//wrong

//Aboutme.Text = String.Format("{0}", reader.GetString(0));//correct

The value 1382086394000 is probably a time value, which is the number of milliseconds since 1970-01-01T00:00:00Z. You can use it to create an ECMAScript Date object using the Date constructor:

var d = new Date(1382086394000);

How you convert that into something readable is up to you. Simply sending it to output should call the internal (and entirely implementation dependent) toString method* that usually prints the equivalent system time in a human readable form, e.g.

Fri Oct 18 2013 18:53:14 GMT+1000 (EST) 

In ES5 there are some other built-in formatting options:

• toDateString
• toTimeString
• toLocaleString

and so on. Note that most are implementation dependent and will be different in different browsers. If you want the same format across all browsers, you'll need to format the date yourself, e.g.:

alert(d.getDate() + '/' + (d.getMonth()+1) + '/' + d.getFullYear());

* The format of Date.prototype.toString has been standardised in ECMAScript 2018. It might be a while before it's ubiquitous across all implementations, but at least the more common browsers support it now.

Once after we build the jar will have the resource files under BOOT-INF/classes or target/classes folder, which is in classpath, use the below method and pass the file under the src/main/resources as method call getAbsolutePath("certs/uat_staging_private.ppk"), even we can place this method in Utility class and the calling Thread instance will be taken to load the ClassLoader to get the resource from class path.

 public String getAbsolutePath(String fileName) throws IOException {
      return Thread.currentThread().getContextClassLoader().getResource(fileName).getFile();
  }

we can add the below tag to tag in pom.xml to include these resource files to build target/classes folder

<resources>
        <resource>
            <directory>src/main/resources</directory>
            <includes>
                <include>**/*.properties</include>
                <include>**/*.ppk</include>
            </includes>
        </resource>
</resources>

I had the same error. My issue was using the wrong parameter name when binding.

Notice :tokenHash in the query, but :token_hash when binding. Fixing one or the other resolves the error in this instance.

// Prepare DB connection
$sql = 'INSERT INTO rememberedlogins (token_hash,user_id,expires_at)
        VALUES (:tokenHash,:user_id,:expires_at)';
$db = static::getDB();
$stmt = $db->prepare($sql);

// Bind values
$stmt->bindValue(':token_hash',$hashed_token,PDO::PARAM_STR);

You can use sed for this. For example:

$ sed -n '/Feb 23 13:55/,/Feb 23 14:00/p' /var/log/mail.log
Feb 23 13:55:01 messagerie postfix/smtpd[20964]: connect from localhost[127.0.0.1]
Feb 23 13:55:01 messagerie postfix/smtpd[20964]: lost connection after CONNECT from localhost[127.0.0.1]
Feb 23 13:55:01 messagerie postfix/smtpd[20964]: disconnect from localhost[127.0.0.1]
Feb 23 13:55:01 messagerie pop3d: Connection, ip=[::ffff:127.0.0.1]
...

How it works

The -n switch tells sed to not output each line of the file it reads (default behaviour).

The last p after the regular expressions tells it to print lines that match the preceding expression.

The expression '/pattern1/,/pattern2/' will print everything that is between first pattern and second pattern. In this case it will print every line it finds between the string Feb 23 13:55 and the string Feb 23 14:00.

It sounds like you're trying to link with your resulting object file with gcc instead of g++:

Note that programs using C++ object files must always be linked with g++, in order to supply the appropriate C++ libraries. Attempting to link a C++ object file with the C compiler gcc will cause "undefined reference" errors for C++ standard library functions:

$ g++ -Wall -c hello.cc
$ gcc hello.o       (should use g++)
hello.o: In function `main':
hello.o(.text+0x1b): undefined reference to `std::cout'
.....
hello.o(.eh_frame+0x11):
  undefined reference to `__gxx_personality_v0'

You can use the text method and pass a function that returns the modified text, using the native String.prototype.replace method to perform the replacement:

?$(".text_div").text(function () {
    return $(this).text().replace("contains", "hello everyone"); 
});?????

Here's a working example.

Even better for fallback is this:

   var alertFallback = true;
   if (typeof console === "undefined" || typeof console.log === "undefined") {
     console = {};
     if (alertFallback) {
         console.log = function(msg) {
              alert(msg);
         };
     } else {
         console.log = function() {};
     }
   }

Simply convert int to NSString use :

  int x=10;

  NSString *strX=[NSString stringWithFormat:@"%d",x];

From linux 14.04 to MySql 5.7, using cat command piped with mysql login:

cat /Desktop/test.sql | sudo mysql -uroot -p 

You can use this method for many MySQL commands to execute directly from Shell. Eg:

echo "USE my_db; SHOW tables;" | sudo mysql -uroot -p 

Make sure you separate your commands with semicolon (';').

I didn't see this approach in the answers above and thought it is a good contribution.

If you dump the preprocessor #defines

gcc -dM -E - < /dev/null
g++ -dM -E -x c++ - < /dev/null

You can usually find stuff that will help you. With compile time logic.

#define __LITTLE_ENDIAN__ 1
#define __BYTE_ORDER__ __ORDER_LITTLE_ENDIAN__

Various compilers may have different defines however.

This works for MVC 5:

<a href="@Url.Action("ActionName", "ControllerName", new { paramName1 = item.paramValue1, paramName2 = item.paramValue2 })" >
    Link text
</a>

You should have a look at numpy if you do matrix manipulation. This is a module mainly written in C, which will be much faster than programming in pure python. Here is an example of how to invert a matrix, and do other matrix manipulation.

from numpy import matrix
from numpy import linalg
A = matrix( [[1,2,3],[11,12,13],[21,22,23]]) # Creates a matrix.
x = matrix( [[1],[2],[3]] )                  # Creates a matrix (like a column vector).
y = matrix( [[1,2,3]] )                      # Creates a matrix (like a row vector).
print A.T                                    # Transpose of A.
print A*x                                    # Matrix multiplication of A and x.
print A.I                                    # Inverse of A.
print linalg.solve(A, x)     # Solve the linear equation system.

You can also have a look at the array module, which is a much more efficient implementation of lists when you have to deal with only one data type.

This code work as well, instead eval the html i'm going to append the script to the head

function RunJS(objID) {
//alert(http_request.responseText);
var c="";
var ob = document.getElementById(objID).getElementsByTagName("script");
for (var i=0; i < ob.length - 1; i++) {
    if (ob[i + 1].text != null) 
       c+=ob[i + 1].text;
}
var s = document.createElement("script");
s.type = "text/javascript";
s.text = c;
document.getElementsByTagName("head")[0].appendChild(s);
}

First create an xpath selector function.

function _x(STR_XPATH) {
    var xresult = document.evaluate(STR_XPATH, document, null, XPathResult.ANY_TYPE, null);
    var xnodes = [];
    var xres;
    while (xres = xresult.iterateNext()) {
        xnodes.push(xres);
    }

    return xnodes;
}

To use the xpath selector with jquery, you can do like this:

$(_x('/html/.//div[@id="text"]')).attr('id', 'modified-text');

Hope this can help.

Once you have defined your chosen commands, you can simply drag and drop the saved file into the Lib folder in your python program files.

>>> import mymodule 
>>> mymodule.myfunc()

Let us think what an interpreter actually is: it's a piece of code that stores values in memory and lets the instructions in a program that it interprets access those values by their names, which are specified inside these instructions. So, the big job of an interpreter is to shape the rules of how we should use the names in those instructions to access the values that the interpreter stores.

On encountering "my", the interpreter creates a lexical variable: a named value that the interpreter can access only while it executes a block, and only from within that syntactic block. On encountering "our", the interpreter makes a lexical alias of a package variable: it binds a name, which the interpreter is supposed from then on to process as a lexical variable's name, until the block is finished, to the value of the package variable with the same name.

The effect is that you can then pretend that you're using a lexical variable and bypass the rules of 'use strict' on full qualification of package variables. Since the interpreter automatically creates package variables when they are first used, the side effect of using "our" may also be that the interpreter creates a package variable as well. In this case, two things are created: a package variable, which the interpreter can access from everywhere, provided it's properly designated as requested by 'use strict' (prepended with the name of its package and two colons), and its lexical alias.

import java.sql.Timestamp;
import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

public class Util {
  public static Timestamp convertStringToTimestamp(String strDate) {
    try {
      DateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
       // you can change format of date
      Date date = formatter.parse(strDate);
      Timestamp timeStampDate = new Timestamp(date.getTime());

      return timeStampDate;
    } catch (ParseException e) {
      System.out.println("Exception :" + e);
      return null;
    }
  }
}

You can use int casting which allows the base specification.

int(b, 2)  # Convert a binary string to a decimal int.

Check what $TERM gives: mine is xterm-color and ls -alG then does colorised output.

If you want to truncate by a number of words and add an ellipsis you can use this function:

truncate(value: string, limit: number = 40, trail: String = '…'): string {
  let result = value || '';

  if (value) {
    const words = value.split(/\s+/);
    if (words.length > Math.abs(limit)) {
      if (limit < 0) {
        limit *= -1;
        result = trail + words.slice(words.length - limit, words.length).join(' ');
      } else {
        result = words.slice(0, limit).join(' ') + trail;
      }
    }
  }

  return result;
}

Example:

truncate('Bacon ipsum dolor amet sirloin tri-tip swine', 5, '…')
> "Bacon ipsum dolor amet sirloin…"

taken from: https://github.com/yellowspot/ng2-truncate/blob/master/src/truncate-words.pipe.ts

If you want to truncate by a number of letters but don't cut words out use this:

truncate(value: string, limit = 25, completeWords = true, ellipsis = '…') {
  let lastindex = limit;
  if (completeWords) {
    lastindex = value.substr(0, limit).lastIndexOf(' ');
  }
  return `${value.substr(0, limit)}${ellipsis}`;
}

Example:

truncate('Bacon ipsum dolor amet sirloin tri-tip swine', 19, true, '…')
> "Bacon ipsum dolor…"

truncate('Bacon ipsum dolor amet sirloin tri-tip swine', 19, false, '…')
> "Bacon ipsum dolor a…"

I got a similar error, the problem stopped when I checked my "Linker -> Input -> Additional Dependencies" list in the project properties. I was missing a semi colon ";" just before "%(AdditionalDependencies)". I also had the same entry in twice. You should edit this list separately for Debug and Release.

Your .gitignore is working, but it still tracks the files because they were already in the index.

To stop this you have to do : git rm -r --cached .idea/

When you commit the .idea/ directory will be removed from your git repository and the following commits will ignore the .idea/ directory.

PS: You could use .idea/ instead of .idea/* to ignore a directory. You can find more info about the patterns on the .gitignore man page.

Helpful quote from the git-rm man page

--cached
    Use this option to unstage and remove paths only from the index. 
    Working tree files, whether modified or not, will be left alone.

With jquery library

<button onclick="$('.inputFile').click();">Select File ...</button>
<input class="inputFile" type="file" style="display: none;">

@Carlo I really like your implementation of this, but I wanted to share my version and how to use it in my ViewModel

First implement ICommand

public class Command : ICommand
{
    public delegate void ICommandOnExecute();
    public delegate bool ICommandOnCanExecute();

    private ICommandOnExecute _execute;
    private ICommandOnCanExecute _canExecute;

    public Command(ICommandOnExecute onExecuteMethod, ICommandOnCanExecute onCanExecuteMethod = null)
    {
        _execute = onExecuteMethod;
        _canExecute = onCanExecuteMethod;
    }

    #region ICommand Members

    public event EventHandler CanExecuteChanged
    {
        add { CommandManager.RequerySuggested += value; }
        remove { CommandManager.RequerySuggested -= value; }
    }

    public bool CanExecute(object parameter)
    {
        return _canExecute?.Invoke() ?? true;
    }

    public void Execute(object parameter)
    {
        _execute?.Invoke();
    }

    #endregion
}

Notice I have removed the parameter from ICommandOnExecute and ICommandOnCanExecute and added a null to the constructor

Then to use in the ViewModel

public Command CommandToRun_WithCheck
{
    get
    {
        return new Command(() =>
        {
            // Code to run
        }, () =>
        {
            // Code to check to see if we can run 
            // Return true or false
        });
    }
}

public Command CommandToRun_NoCheck
{
    get
    {
        return new Command(() =>
        {
            // Code to run
        });
    }
}

I just find this way cleaner as I don't need to assign variables and then instantiate, it all done in one go.

Simply specify the desired framerate in "-r " option before the input file:

ffmpeg -y -r 24 -i seeing_noaudio.mp4 seeing.mp4

Options affect the next file AFTER them. "-r" before an input file forces to reinterpret its header as if the video was encoded at the given framerate. No recompression is necessary. There was a small utility avifrate.exe to patch avi file headers directly to change the framerate. ffmpeg command above essentially does the same, but has to copy the entire file.

For PostgreSQL... It didn't work for me with index; it gave me an error, so I did this:

alter table table_name
add unique(column_name_1,column_name_2);

PostgreSQL gave unique index its own name. I guess you can change the name of index in the options for the table, if it is needed to be changed...

[firstNameTextField setContentVerticalAlignment:UIControlContentVerticalAlignmentCenter];

Astrée is the most robust and sophisticated tool out there, IMHO.

Html.DisplayFor() will render the DisplayTemplate that matches the property's type.

If it can't find any, I suppose it invokes .ToString().

If you don't know about display templates, they're partial views that can be put in a DisplayTemplates folder inside the view folder associated to a controller.

Example:

If you create a view named String.cshtml inside the DisplayTemplates folder of your views folder (e.g Home, or Shared) with the following code:

@model string

@if (string.IsNullOrEmpty(Model)) {
   <strong>Null string</strong>
}
else {
   @Model
}

Then @Html.DisplayFor(model => model.Title) (assuming that Title is a string) will use the template and display <strong>Null string</strong> if the string is null, or empty.

Switch to AppCompatActivity and add a 25 dp paddingTop on the toolbar and turn on

<item name="android:windowTranslucentStatus">true</item>

Then, the will toolbar go up top the top

The csv module handles csv files by row. If you want to handle it by column, pandas is a good solution.

Besides, there are 2 ways to get all (or specific) columns with pure simple Python code.

1. csv.DictReader

with open('demo.csv') as file:
    data = {}
    for row in csv.DictReader(file):
        for key, value in row.items():
            if key not in data:
                data[key] = []
            data[key].append(value)

It is easy to understand.

2. csv.reader with zip

with open('demo.csv') as file:
    data = {values[0]: values[1:] for values in zip(*csv.reader(file))}

This is not very clear, but efficient.

zip(x, y, z) transpose (x, y, z), while x, y, z are lists. *csv.reader(file) make (x, y, z) for zip, with column names.

Demo Result

The content of demo.csv:

a,b,c
1,2,3
4,5,6
7,8,9

The result of 1:

>>> print(data)
{'c': ['3', '6', '9'], 'b': ['2', '5', '8'], 'a': ['1', '4', '7']}

The result of 2:

>>> print(data)
{'c': ('3', '6', '9'), 'b': ('2', '5', '8'), 'a': ('1', '4', '7')}

var ids = [];

    $(document).ready(function($) {    
    $(".color_cell").bind('click', function() {
        alert('Test');

        ids.push(this.id);       
    });
});

Simple, here replace the "APP" by name of the app you want to launch.

export APP_HOME=/Applications/APP.app/Contents/MacOS
export PATH=$PATH:$APP_HOME

Thanks me later.

This script logs all the file names and ids in the drive:

// Log the name and id of every file in the user's Drive
function listFiles() {
  var files = DriveApp.getFiles();
  while ( files.hasNext() ) {
    var file = files.next();
    Logger.log( file.getName() + ' ' + file.getId() );
  }
}  

Also, the "Files: list" page has a form at the end that lists the metadata of all the files in the drive, that can be used in case you need but a few ids.

One solution is to actually use an integer array instead of separate test strings:

You could loop parse the response from JOptionPane.showInputDialog into the individual elements of the array.

Arrays.sort could be used to sort them to allow you to pick out the 2 highest values.

The average can be easily calculated then by adding these 2 values & dividing by 2.

int[] testScore = new int[3];

for (int i = 0; i < testScore.length; i++) {
   testScore[i] = Integer.parseInt(JOptionPane.showInputDialog("Please input mark for test " + i + ": "));
}

Arrays.sort(testScore);
System.out.println("Average: " + (testScore[1] + testScore[2])/2.0);

1. The SQL Joins clause is used to combine records from two or more tables in a database. A JOIN is a means for combining fields from two tables by using values common to each.

2. The SQL UNION operator combines the result of two or more SELECT statements. Each SELECT statement within the UNION must have the same number of columns. The columns must also have similar data types. Also, the columns in each SELECT statement must be in the same order.

for example: table 1 customers/table 2 orders

inner join:

SELECT ID, NAME, AMOUNT, DATE

FROM CUSTOMERS?

INNER JOIN ORDERS?

ON CUSTOMERS.ID = ORDERS.CUSTOMER_ID;

union:

SELECT ID, NAME, AMOUNT, DATE

?FROM CUSTOMERS?

LEFT JOIN ORDERS?

ON CUSTOMERS.ID = ORDERS.CUSTOMER_ID

UNION

SELECT ID, NAME, AMOUNT, DATE ? FROM CUSTOMERS?

RIGHT JOIN ORDERS?

ON CUSTOMERS.ID = ORDERS.CUSTOMER_ID;

there is component ready to use (rc5 compatible) ng2-steps which uses Compiler to inject component to step container and service for wiring everything together (data sync)

    import { Directive , Input, OnInit, Compiler , ViewContainerRef } from '@angular/core';

import { StepsService } from './ng2-steps';

@Directive({
  selector:'[ng2-step]'
})
export class StepDirective implements OnInit{

  @Input('content') content:any;
  @Input('index') index:string;
  public instance;

  constructor(
    private compiler:Compiler,
    private viewContainerRef:ViewContainerRef,
    private sds:StepsService
  ){}

  ngOnInit(){
    //Magic!
    this.compiler.compileComponentAsync(this.content).then((cmpFactory)=>{
      const injector = this.viewContainerRef.injector;
      this.viewContainerRef.createComponent(cmpFactory, 0,  injector);
    });
  }

}

You can use C#, Javascript, Boo.

Unless computing requirement for the function you write cause heavy load on processor, Javascript gives good enough performance for most cases.

Short Code

public class DB {

    public static Connection c;

    public static Connection getConnection() throws Exception {
        if (c == null) {
            Class.forName("com.mysql.jdbc.Driver");
            c =DriverManager.getConnection("jdbc:mysql://localhost:3306/DATABASE", "USERNAME", "Password");
        }
        return c;
    }

    // Send data TO Database
    public static void setData(String sql) throws Exception {
        DB.getConnection().createStatement().executeUpdate(sql);
    }

    // Get Data From Database
    public static ResultSet getData(String sql) throws Exception {
        ResultSet rs = DB.getConnection().createStatement().executeQuery(sql);
        return rs;
    }
}

For future reference if somebody else runs into this problem. I found a solution that should work in all modern browsers:

select{
    scrollbar-width: none; /*For Firefox*/;
    -ms-overflow-style: none;  /*For Internet Explorer 10+*/;
}

select:-webkit-scrollbar { /*For WebKit Browsers*/
    width: 0;
    height: 0;
}

Basically this way the scrollbar is set to a width of 0 and is hence not displayed.

An HTTP message may have a body of data sent after the header lines. In a response, this is where the requested resource is returned to the client (the most common use of the message body), or perhaps explanatory text if there's an error. In a request, this is where user-entered data or uploaded files are sent to the server.

It's quite simple.

All you need to do is:

• Right click above application tag and click on Generate
• Click on XML tag
• Click on user-permission
• Enter the name of your permission.

Lets take a vector 'point' which has numbers from 1 to 5

point = c(1,2,3,4,5)

if we want to append a number 6 anywhere inside the vector then below command may come handy

i) Vectors

new_var = append(point, 6 ,after = length(point))

ii) columns of a table

new_var = append(point, 6 ,after = length(mtcars$mpg))

The command append takes three arguments:

1. the vector/column to be modified.
2. value to be included in the modified vector.
3. a subscript, after which the values are to be appended.

simple...!! Apologies in case of any...!

A lot of you have great approaches, but the goal here is to be generic and defined a array pipe that is extremely reusable across all cases in relationship to *ngFor.

callback.pipe.ts (don't forget to add this to your module's declaration array)

import { PipeTransform, Pipe } from '@angular/core';

@Pipe({
    name: 'callback',
    pure: false
})
export class CallbackPipe implements PipeTransform {
    transform(items: any[], callback: (item: any) => boolean): any {
        if (!items || !callback) {
            return items;
        }
        return items.filter(item => callback(item));
    }
}

Then in your component, you need to implement a method with the following signuature (item: any) => boolean, in my case for example, I called it filterUser, that filters users' age that are greater than 18 years.

Your Component

@Component({
  ....
})
export class UsersComponent {
  filterUser(user: IUser) {
    return !user.age >= 18
  }
}

And last but not least, your html code will look like this:

Your HTML

<li *ngFor="let user of users | callback: filterUser">{{user.name}}</li>

As you can see, this Pipe is fairly generic across all array like items that need to be filter via a callback. In mycase, I found it to be very useful for *ngFor like scenarios.

Hope this helps!!!

codematrix

This depends on what function1 is doing.

If function1 is doing some simple synchrounous javascript, like updating a div value or something, then function2 will fire after function1 has completed.

If function1 is making an asynchronous call, such as an AJAX call, you will need to create a "callback" method (most ajax API's have a callback function parameter). Then call function2 in the callback. eg:

function1()
{
  new AjaxCall(ajaxOptions, MyCallback);
}

function MyCallback(result)
{
  function2(result);
}

I have tried the above answers and the best i think is this one

@item.First_Name.Substring(0,1)

In this i could get the first letter of the string

Just ask yourself how many statements need to execute for F(n) to complete.

For F(1), the answer is 1 (the first part of the conditional).

For F(n), the answer is F(n-1) + F(n-2).

So what function satisfies these rules? Try aⁿ (a > 1):

aⁿ == a^(n-1) + a^(n-2)

Divide through by a^(n-2):

a² == a + 1

Solve for a and you get (1+sqrt(5))/2 = 1.6180339887, otherwise known as the golden ratio.

So it takes exponential time.

We can pass string value to main method as argument without using commandline argument concept in java through Netbean

 package MainClass;
 import java.util.Scanner;
 public class CmdLineArgDemo {

static{
 Scanner readData = new Scanner(System.in);   
 System.out.println("Enter any string :");
 String str = readData.nextLine();
 String [] str1 = str.split(" ");
 // System.out.println(str1.length);
 CmdLineArgDemo.main(str1);
}  

   public static void main(String [] args){
      for(int i = 0 ; i<args.length;i++) {
        System.out.print(args[i]+" ");
      }
    }
  }

Output

Enter any string :

This worked for me under 10.7.5 with EPD_free-7.3-2 from Enthought:

Install EPD free, then follow the step in the following link to create .bash_profile file.

http://redfinsolutions.com/blog/creating-bashprofile-your-mac

And add the following to the file.

PATH="/Library/Frameworks/Python.framework/Versions/Current/bin:$(PATH)}"
export PATH

Execute the following command in Terminal

$ sudo easy_install pandas

When finished, launch PyLab and type:

In [1]: import pandas

In [2]: plot(arange(10))

This should open a plot with a diagonal straight line.

You can use zero-length positive look-aheads to specify each of your constraints separately:

(?=.{8,})(?=.*\p{Lu}.*\p{Lu})(?=.*[!@#$&*])(?=.*[0-9])(?=.*\p{Ll}.*\p{Ll})

If your regex engine doesn't support the \p notation and pure ASCII is enough, then you can replace \p{Lu} with [A-Z] and \p{Ll} with [a-z].

call function on load:

<video onload="doWhatYouNeedTo()" src="demo.mp4" id="video">

get video duration

var video = document.getElementById("video");
var duration = video.duration;

The only way I succeed to not having an error because of NULL, or special characters or empty string is by doing this:

SELECT REGEXP_REPLACE(COALESCE(<column>::character varying, '0'), '[^0-9]*' ,'0')::integer FROM table

To compare the current branch against master branch:

$ git diff --name-status master

To compare any two branches:

$ git diff --name-status firstbranch..yourBranchName

There is more options to git diff in the official documentation (and specifically --name-status option).

Use the starts with selector

$('input[name^="pages_title"]').each(function() {
    alert($(this).val());
});

Note: In agreement with @epascarello that the better solution is to add a class to the elements and reference that class.

I would vote no. Hibernate doesn't seem to understand when datatypes for columns have changed. Examples (using MySQL):

String with @Column(length=50)  ==> varchar(50)
changed to
String with @Column(length=100) ==> still varchar(50), not changed to varchar(100)

@Temporal(TemporalType.TIMESTAMP,TIME,DATE) will not update the DB columns if changed

There are probably other examples as well, such as pushing the length of a String column up over 255 and seeing it convert to text, mediumtext, etc etc.

Granted, I don't think there is really a way to "convert datatypes" with without creating a new column, copying the data and blowing away the old column. But the minute your database has columns which don't reflect the current Hibernate mapping you are living very dangerously...

Flyway is a good option to deal with this problem:

http://flywaydb.org

In Swift 3.0

let screenSize = UIScreen.main.bounds
let screenWidth = screenSize.width
let screenHeight = screenSize.height

In older swift: Do something like this:

let screenSize: CGRect = UIScreen.mainScreen().bounds

then you can access the width and height like this:

let screenWidth = screenSize.width
let screenHeight = screenSize.height

if you want 75% of your screen's width you can go:

let screenWidth = screenSize.width * 0.75

Swift 4.0

// Screen width.
public var screenWidth: CGFloat {
    return UIScreen.main.bounds.width
}

// Screen height.
public var screenHeight: CGFloat {
    return UIScreen.main.bounds.height
}

In Swift 5.0

let screenSize: CGRect = UIScreen.main.bounds

you can achieve this easily without writing Js. Just add an attribute called data-page-length={put your number here}. see example below, I used 100 for example

<table id="datatable-keytable" data-page-length='100' class="p-table table table-bordered" width="100%">

Your subquery is selecting two columns, while you are using it to project one column (as part of the outer SELECT clause). You can only select one column from such a query in this context.

Consider joining to the users table instead; this will give you more flexibility when selecting what columns you want from users.

SELECT
topics.id,
topics.name,
topics.post_count,
topics.view_count,
COUNT( posts.solved_post ) AS solved_post,
users.username AS posted_by,
users.id AS posted_by_id

FROM topics

LEFT OUTER JOIN posts ON posts.topic_id = topics.id
LEFT OUTER JOIN users ON users.id = posts.posted_by

WHERE topics.cat_id = :cat
GROUP BY topics.id

First you should create a form with or without Border (border-less is preferred for these things)

public class SplashForm : Form
{
    Form _Parent;
    BackgroundWorker worker;
    public SplashForm(Form parent)
    {
         InitializeComponent();
         BackgroundWorker worker = new BackgroundWorker();
         this.worker.DoWork += new System.ComponentModel.DoWorkEventHandler(this.worker _DoWork);
         backgroundWorker1.RunWorkerAsync();
         _Parent = parent;
    }
    private void worker _DoWork(object sender, DoWorkEventArgs e)
    {
         Thread.sleep(500);
         this.hide();
         _Parent.show();
    }     
}

At Main you should use that

   static class Program
        {
            [STAThread]
            static void Main()
            {
                Application.EnableVisualStyles();
                Application.SetCompatibleTextRenderingDefault(false);
                Application.Run(new SplashForm());
            }
        }

Try this:

Use back-ticks for NAME

CREATE TABLE `teachers` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `name` varchar(50) NOT NULL,
  `addr` varchar(255) NOT NULL,
  `phone` int(10) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8

If your business class is directly used by your UI is preferrable to use IDataErrorInfo because it put logic closer to their owner.

If your business class is a stub class created by a reference to an WCF/XmlWeb service then you can not/must not use IDataErrorInfo nor throw Exception for use with ExceptionValidationRule. Instead you can:

• Use custom ValidationRule.
• Define a partial class in your WPF UI project and implements IDataErrorInfo.

Here is a one line lambda that also works:

df["TrueFalse"] = df['col1'].apply(lambda x: 1 if any(i in x for i in searchfor) else 0)

Input:

searchfor = ['og', 'at']

df = pd.DataFrame([('cat', 1000.0), ('hat', 2000000.0), ('dog', 1000.0), ('fog', 330000.0),('pet', 330000.0)], columns=['col1', 'col2'])

   col1  col2
0   cat 1000.0
1   hat 2000000.0
2   dog 1000.0
3   fog 330000.0
4   pet 330000.0

Apply Lambda:

df["TrueFalse"] = df['col1'].apply(lambda x: 1 if any(i in x for i in searchfor) else 0)

Output:

    col1    col2        TrueFalse
0   cat     1000.0      1
1   hat     2000000.0   1
2   dog     1000.0      1
3   fog     330000.0    1
4   pet     330000.0    0

You can also use % as follows:

source = "#{ROOT_DIR}/%s/App.config" % project

This approach works with ' (single) quotation mark as well.

You can easily define such function and use it then:

ifnull <- function(x,y) {
  if(is.na(x)==TRUE) 
    return (y)
  else 
    return (x);
}

or same minified version:

ifnull <- function(x,y) {if(is.na(x)==TRUE) return (y) else return (x);}

This worked fine for me:

        $('#myelement').datetimepicker({
            dateFormat: "yy-mm-dd",
            timeFormat:  "hh:mm:ss"
        });

Joseph forgot to add the value in his example with withDefault. Here is the code I ended up using:

Map map = [:].withDefault { key -> return [] }
listOfObjects.each { map.get(it.myKey).add(it.myValue) }

I prefer to convert arrays to strings:

Assert.assertEquals(
                Arrays.toString(values),
                Arrays.toString(new int[] { 7, 8, 9, 3 }));

this way I can see clearly where wrong values are. This works effectively only for small sized arrays, but I rarely use arrays with more items than 7 in my unit tests.

This method works for primitive types and for other types when overload of toString returns all essential information.

Here it is:

def put4ChannelImageOn4ChannelImage(back, fore, x, y):
    rows, cols, channels = fore.shape    
    trans_indices = fore[...,3] != 0 # Where not transparent
    overlay_copy = back[y:y+rows, x:x+cols] 
    overlay_copy[trans_indices] = fore[trans_indices]
    back[y:y+rows, x:x+cols] = overlay_copy

#test
background = np.zeros((1000, 1000, 4), np.uint8)
background[:] = (127, 127, 127, 1)
overlay = cv2.imread('imagee.png', cv2.IMREAD_UNCHANGED)
put4ChannelImageOn4ChannelImage(background, overlay, 5, 5)

The "Spring Boot" way is to use a CommandLineRunner. Just add beans of that type and you are good to go. In Spring 4.1 (Boot 1.2) there is also a SmartInitializingBean which gets a callback after everything has initialized. And there is SmartLifecycle (from Spring 3).

Code Runner Extension will only let you "run" java files.

To truly debug 'Java' files follow the quick one-time setup:

• Install Java Debugger Extension in VS Code and reload.
• open an empty folder/project in VS code.
• create your java file (s).
• create a folder .vscode in the same folder.
• create 2 files inside .vscode folder: tasks.json and launch.json
• copy paste below config in tasks.json:

{
    "version": "2.0.0",
    "type": "shell",
    "presentation": {
        "echo": true,
        "reveal": "always",
        "focus": false,
        "panel": "shared"
    },
    "isBackground": true,
    "tasks": [
        {
            "taskName": "build",
            "args": ["-g", "${file}"],
            "command": "javac"
        }
    ]
}

• copy paste below config in launch.json:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Debug Java",
            "type": "java",
            "request": "launch",
            "externalConsole": true,                //user input dosen't work if set it to false :(
            "stopOnEntry": true,
            "preLaunchTask": "build",                 // Runs the task created above before running this configuration
            "jdkPath": "${env:JAVA_HOME}/bin",        // You need to set JAVA_HOME enviroment variable
            "cwd": "${workspaceRoot}",
            "startupClass": "${workspaceRoot}${file}",
            "sourcePath": ["${workspaceRoot}"],   // Indicates where your source (.java) files are
            "classpath": ["${workspaceRoot}"],    // Indicates the location of your .class files
            "options": [],                             // Additional options to pass to the java executable
            "args": []                                // Command line arguments to pass to the startup class
        }

    ],
    "compounds": []
}

You are all set to debug java files, open any java file and press F5 (Debug->Start Debugging).

Tip: *To hide .class files in the side explorer of VS code, open settings of VS code and paste the below config:

"files.exclude": {
        "*.class": true
    }

Use concat() function instead of + like this:

select concat(firstname, lastname) as "Name" from test.student

With respect to binning functions, I didn't expect the result of the functions offered so far. Namely, if my binwidth is 0.001, these functions were centering the bins on 0.0005 points, whereas I feel it's more intuitive to have the bins centered on 0.001 boundaries.

In other words, I'd like to have

Bin 0.001 contain data from 0.0005 to 0.0014
Bin 0.002 contain data from 0.0015 to 0.0024
...

The binning function I came up with is

my_bin(x,width)     = width*(floor(x/width+0.5))

Here's a script to compare some of the offered bin functions to this one:

rint(x) = (x-int(x)>0.9999)?int(x)+1:int(x)
bin(x,width)        = width*rint(x/width) + width/2.0
binc(x,width)       = width*(int(x/width)+0.5)
mitar_bin(x,width)  = width*floor(x/width) + width/2.0
my_bin(x,width)     = width*(floor(x/width+0.5))

binwidth = 0.001

data_list = "-0.1386 -0.1383 -0.1375 -0.0015 -0.0005 0.0005 0.0015 0.1375 0.1383 0.1386"

my_line = sprintf("%7s  %7s  %7s  %7s  %7s","data","bin()","binc()","mitar()","my_bin()")
print my_line
do for [i in data_list] {
    iN = i + 0
    my_line = sprintf("%+.4f  %+.4f  %+.4f  %+.4f  %+.4f",iN,bin(iN,binwidth),binc(iN,binwidth),mitar_bin(iN,binwidth),my_bin(iN,binwidth))
    print my_line
}

and here's the output

   data    bin()   binc()  mitar()  my_bin()
-0.1386  -0.1375  -0.1375  -0.1385  -0.1390
-0.1383  -0.1375  -0.1375  -0.1385  -0.1380
-0.1375  -0.1365  -0.1365  -0.1375  -0.1380
-0.0015  -0.0005  -0.0005  -0.0015  -0.0010
-0.0005  +0.0005  +0.0005  -0.0005  +0.0000
+0.0005  +0.0005  +0.0005  +0.0005  +0.0010
+0.0015  +0.0015  +0.0015  +0.0015  +0.0020
+0.1375  +0.1375  +0.1375  +0.1375  +0.1380
+0.1383  +0.1385  +0.1385  +0.1385  +0.1380
+0.1386  +0.1385  +0.1385  +0.1385  +0.1390

The following code works for me:

Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, 2);

And here is the result:

protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent)
{ 
    super.onActivityResult(requestCode, resultCode, imageReturnedIntent);

    if(resultCode == RESULT_OK)
    {
        Uri selectedImage = imageReturnedIntent.getData();
        ImageView photo = (ImageView) findViewById(R.id.add_contact_label_photo);
        Bitmap mBitmap = null;
        try
        {
            mBitmap = Media.getBitmap(this.getContentResolver(), selectedImage);
        }
        catch (IOException e)
        {
            e.printStackTrace();
        }
    }
}

I always get merge conflicts when doing just git merge feature-branch. This seems to work for me:

git checkout -b feature-branch

Do a bunch of code changes...

git merge -s ours master 

git checkout master

git merge feature-branch

or

Because a reference is 'managed', but not hydrated, it can also allow you to remove an entity by ID, without needing to load it into memory first.

As you can't remove an unmanaged entity, it's just plain silly to load all fields using find(...) or createQuery(...), only to immediately delete it.

MyLargeObject myObject = em.getReference(MyLargeObject.class, objectId);
em.remove(myObject);

Assume logs are already put to stdout/stderr, and have systemd unit's log in /var/log/syslog

If you mean HashCode as in .GetHashCode(), I'm afraid you can't go back. Hash functions are not bi-directional, you can go 'forward' only, not back.

Follow Oded's suggestion if you need to get the color based on the hexadecimal value of the color.

It's worth mentioning that the validation properties are different for forms and form elements (note that touched and untouched are for fields only):

Input fields have the following states:

$untouched The field has not been touched yet
$touched The field has been touched
$pristine The field has not been modified yet
$dirty The field has been modified
$invalid The field content is not valid
$valid The field content is valid

They are all properties of the input field, and are either true or false.

Forms have the following states:

$pristine No fields have been modified yet
$dirty One or more have been modified
$invalid The form content is not valid
$valid The form content is valid
$submitted The form is submitted

They are all properties of the form, and are either true or false.

Any Activity that restarts has its onResume() method executed first.

To use this method, do this:

@Override
public void onResume(){
    super.onResume();
    // put your code here...

}

Involve following steps to resolve the issue:

1) Install the CLI and env preset

$ npm install --save-dev babel-cli babel-preset-env

2) Create a .babelrc file

{
  "presets": ["env"]
}

3) configure npm start in package.json

"scripts": {
    "start": "babel-node ./server/app.js",
    "test": "echo \"Error: no test specified\" && exit 1"
  }

4) then start app

$ npm start

Are you going to want to do a setInterval()?

setInterval(function(){get_fb();}, 10000);

Or:

setInterval(get_fb, 10000);

Or, if you want it to run only after successfully completing the call, you can set it up in your .ajax().success() callback:

function get_fb(){
    var feedback = $.ajax({
        type: "POST",
        url: "feedback.php",
        async: false
    }).success(function(){
        setTimeout(function(){get_fb();}, 10000);
    }).responseText;

    $('div.feedback-box').html(feedback);
}

Or use .ajax().complete() if you want it to run regardless of result:

function get_fb(){
    var feedback = $.ajax({
        type: "POST",
        url: "feedback.php",
        async: false
    }).complete(function(){
        setTimeout(function(){get_fb();}, 10000);
    }).responseText;

    $('div.feedback-box').html(feedback);
}

Here is a demonstration of the two. Note, the success works only once because jsfiddle is returning a 404 error on the ajax call.

None of the above worked for me. I had a version of the app on the device that could not be uninstalled as it was corrupt somehow. I had to factory reset the device. Not too bothered cause it was a just a dev device

if you want to "clean" the new lines, flamebaud comment using regex @"[\r\n]+" is the best choice.

using System;
using System.Text.RegularExpressions;

class MainClass {
  public static void Main (string[] args) {
    string str = "AAA\r\nBBB\r\n\r\n\r\nCCC\r\r\rDDD\n\n\nEEE";

    Console.WriteLine (str.Replace(System.Environment.NewLine, "-"));
    /* Result:
    AAA
    -BBB
    -
    -
    -CCC


    DDD---EEE
    */
    Console.WriteLine (Regex.Replace(str, @"\r\n?|\n", "-"));
    // Result:
    // AAA-BBB---CCC---DDD---EEE

    Console.WriteLine (Regex.Replace(str, @"[\r\n]+", "-"));
    // Result:
    // AAA-BBB-CCC-DDD-EEE
  }
}

You're probably returning an object that's on the stack. That is, return_Object() probably looks like this:

Object& return_Object()
{
    Object object_to_return;
    // ... do stuff ...

    return object_to_return;
}

If this is what you're doing, you're out of luck - object_to_return has gone out of scope and been destructed at the end of return_Object, so myObject refers to a non-existent object. You either need to return by value, or return an Object declared in a wider scope or newed onto the heap.

Thanks for this, very useful.

It would help though if the code were syntactically correct. As it is there's a { too many around line 20. Which I'm afraid means nobody actually tried this out.

I may be crazy, but after trying it on a few valid and invalid addresses, the only version of validate_ip() that worked was this:

    public function validate_ip($ip)
    {
        if (filter_var($ip, FILTER_VALIDATE_IP, FILTER_FLAG_NO_PRIV_RANGE) === false)
            return false;
        if (filter_var($ip, FILTER_VALIDATE_IP, FILTER_FLAG_NO_RES_RANGE) === false)
            return false;
        if (filter_var($ip, FILTER_VALIDATE_IP, FILTER_FLAG_IPV4) === false && filter_var($ip, FILTER_VALIDATE_IP, FILTER_FLAG_IPV6) === false)
            return false;

        return true;
    }

Install Multiple Versions Of Xcode using the Xcode-Install Ruby Gem

You can do this whole process a lot easier if you use the xcode-install RubyGem.

If you already have a working installation of the Xcode CommandLineTools and Ruby (I'd suggest using Homebrew for installing Ruby) but I think it works with the Ruby supplied by macOS as well if you install the Gem either using sudo or as a user install. (Details on the GitHub page) Basically:

    $ gem install xcode-install
    $ xcversion list
    6.0.1
    6.1
    6.1.1
    6.2 (installed)
    6.3
    $ xcversion install 8
    ######################################################################## 100.0%
    Please authenticate for Xcode installation...

    Xcode 8
    Build version 6D570

To select a version as active, you'll run:
$ xcversion select 8

To select a version as active and change the symlink at /Applications/Xcode, you'll run:
$ xcversion select 8 --symlink

xcode-install can also manage your local simulators using the simulators command.

Read the instructions on the GitHub Project page for more info.

If you have a lot of these to check you might want to store a list of the mappings and just loop over that, instead of having a bunch of if/else statements. Something like:

var CODE_TO_LOCATION = {
  'ST1': 'stoke central',
  'ST2': 'stoke north',
  // ...
};

function getLocation(text) {
  for (var code in CODE_TO_LOCATION) {
    if (text.indexOf(code) != -1) {
      return CODE_TO_LOCATION[code];
    }
  }
  return null;
}

This way you can easily add more code/location mappings. And if you want to handle more than one location you could just build up an array of locations in the function instead of just returning the first one you find.

Form1 OpenNewForm = new Form1();
OpenNewForm.Show();

"OpenNewForm" is the name of the Form. In the second the form opens.

If you want to close the previous form:

this.Close();

If you want to use optional arguments, but not named arguments, then this approach worked for me. I think this is much easier code to follow.

REM Get argument values.  If not specified, use default values.
IF "%1"=="" ( SET "DatabaseServer=localhost" ) ELSE ( SET "DatabaseServer=%1" )
IF "%2"=="" ( SET "DatabaseName=MyDatabase" ) ELSE ( SET "DatabaseName=%2" )

REM Do work
ECHO Database Server = %DatabaseServer%
ECHO Database Name   = %DatabaseName%

Target-Action allows three different forms of action selector:

- (void)action
- (void)action:(id)sender
- (void)action:(id)sender forEvent:(UIEvent *)event

Without looping

I am using this if I simply want to strip the extension from a filename or variable (without listing any directories or existing files):

for %%f in ("%filename%") do set filename=%%~nf

If you want to strip the extension from a full path, use %%dpnf instead:

for %%f in ("%path%") do set path=%%~dpnf

Example:

(Use directly in the console)

@for %f in ("file name.dat") do @echo %~nf
@for %f in ("C:\Dir\file.dat") do @echo %~dpnf

OUTPUT:

file name
C:\Dir\file

If you use GET method instead of POST then we can't the form filed values. If you use window.opener.location.href = window.opener.location.href; then we can fire the db and we can get the value but only thing is the JSP is not refreshing eventhough the scriplet having the form values.

Here an alternative using SUBSTRING

SELECT
            SUBSTRING([Field], LEN([Field]) - 2, 3) [Right3],
            SUBSTRING([Field], 0, LEN([Field]) - 2) [TheRest]
    FROM 
            [Fields]

with fiddle

You could do it this way ..

var mystr = 'is my name.';_x000D_
mystr = mystr.replace (/^/,'John ');_x000D_
_x000D_
console.log(mystr);

disclaimer: http://xkcd.com/208/

 <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

In my case I get the same error title could not resolve all dependencies for configuration

However suberror said, it was due to a linting jar not loaded with its url given saying status 502 received, I ran the deployment command again, this time it succeeded.

Whatever method you choose is not freeing you from performing the same validation on at the back end.

Go to the "Server" view, then double-click the Tomcat server you're running. The access log files are stored relative to the path in the "Server path" field, which itself is relative to the workspace path.

For @atari2600, this is what the answer would look like using ToLookup in lambda syntax:

var x = listOfCustomObjects
    .GroupBy(o => o.PropertyName)
    .ToLookup(customObject => customObject);

Basically, it takes the IGrouping and materializes it for you into a dictionary of lists, with the values of PropertyName as the key.

And why not making a HTTP Request on the script and ignoring the response ?

http://php.net/manual/en/function.httprequest-send.php

If you make your request on the script you need to call your webserver will run it in background and you can (in your main script) show a message telling the user that the script is running.

You cannot create different "variable names" but you can create different object properties. There are many ways to do whatever it is you're actually trying to accomplish. In your case I would just do

for (var i = myArray.length - 1; i >= 0; i--) {    console.log(eval(myArray[i])); }; 

More generally you can create object properties dynamically, which is the type of flexibility you're thinking of.

var result = {}; for (var i = myArray.length - 1; i >= 0; i--) {     result[myArray[i]] = eval(myArray[i]);   }; 

I'm being a little handwavey since I don't actually understand language theory, but in pure Javascript (including Node) references (i.e. variable names) are happening at a higher level than at runtime. More like at the call stack; you certainly can't manufacture them in your code like you produce objects or arrays. Browsers do actually let you do this anyway though it's terrible practice, via

window['myVarName'] = 'namingCollisionsAreFun';  

(per comment)

I suggest you to use provider. Provide is good when you want to configure it first before to use (against Service/Factory)

Something like:

.provider('Magazines', function() {

    this.url = '/';
    this.urlArray = '/';
    this.organId = 'Default';

    this.$get = function() {
        var url = this.url;
        var urlArray = this.urlArray;
        var organId = this.organId;

        return {
            invoke: function() {
                return ......
            }
        }
    };

    this.setUrl  = function(url) {
        this.url = url;
    };

   this.setUrlArray  = function(urlArray) {
        this.urlArray = urlArray;
    };

    this.setOrganId  = function(organId) {
        this.organId = organId;
    };
});

.config(function(MagazinesProvider){
    MagazinesProvider.setUrl('...');
    MagazinesProvider.setUrlArray('...');
    MagazinesProvider.setOrganId('...');
});

And now controller:

function MyCtrl($scope, Magazines) {        

        Magazines.invoke();

       ....

}

Well, in my case I had to test a Phone Number with the help of regex, and I was getting the same error,

Invalid regular expression: /+923[0-9]{2}-(?!1234567)(?!1111111)(?!7654321)[0-9]{7}/: Nothing to repeat'

So, what was the error in my case was that + operator after the / in the start of the regex. So enclosing the + operator with square brackets [+], and again sending the request, worked like a charm.

Following will work:

/[+]923[0-9]{2}-(?!1234567)(?!1111111)(?!7654321)[0-9]{7}/

This answer may be helpful for those, who got the same type of error, but their chances of getting the error from this point of view, as mine! Cheers :)

That's as easy as

IsNull(FieldName, 0)

Or more completely:

SELECT iar.Description, 
  ISNULL(iai.Quantity,0) as Quantity, 
  ISNULL(iai.Quantity * rpl.RegularPrice,0) as 'Retail', 
  iar.Compliance 
FROM InventoryAdjustmentReason iar
LEFT OUTER JOIN InventoryAdjustmentItem iai  on (iar.Id = iai.InventoryAdjustmentReasonId)
LEFT OUTER JOIN Item i on (i.Id = iai.ItemId)
LEFT OUTER JOIN ReportPriceLookup rpl on (rpl.SkuNumber = i.SkuNo)
WHERE iar.StoreUse = 'yes'

If the string should be of fixed length, then substr from base R can be used. But, we can get the position of the . with regexpr and use that in substr

substr(a, 1, regexpr("\\.", a)-1)
#[1] "NM_020506"    "NM_020519"    "NM_001030297" "NM_010281"    "NM_011419"    "NM_053155"   

This works for me,

List<string> lstRemoveColumns = new List<string>() { "ColValue1", "ColVal2", "ColValue3", "ColValue4" };
List<DataRow> rowsToDelete = new List<DataRow>();

foreach (DataRow row in dt.Rows) {
    if (lstRemoveColumns.Contains(row["ColumnName"].ToString())) {
        rowsToDelete.Add(row);
    }
}

foreach (DataRow row in rowsToDelete) {
    dt.Rows.Remove(row);
}

dt.AcceptChanges();

Looking again at your question, I think I see what's wrong with your conf file. You set:

fullresolution=1366x768 windowresolution=1366x768

That's why you're getting the letterboxing (black on either side). You've essentially told Dosbox that your screen is the same size as your window, but your screen is actually bigger, 1600x900 (or higher) per the Googled specs for that computer. So the 'difference' shows up in black. So you either should change fullresolution to your actual screen resolution, or revert to fullresolution=original default, and only specify the window resolution.

So now I wonder if you really want fullscreen, though your question asks about only a window. For you are getting a window, but you sized it short of your screen, hence the two black stripes (letterboxing). If you really want fullscreen, then you need to specify the actual resolution of your screen. 1366x768 is not big enough.

The next issue is, what's the resolution of the program itself? It won't go past its own resolution. So if the program/game is (natively) say 1280x720 (HD), then your window resolution setting shouldn't be bigger than that (remember, it's fixed not dynamic when you use AxB as windowresolution).

Example: DOS Lotus 123 will only extend eight columns and 20 rows. The bigger the Dosbox, the bigger the text, but not more columns and rows. So setting a higher windowresolution for that, only results in bigger text, not more columns and rows. After that you'll have letterboxing.

Hope this helps you better.

Working solution:

Bootstrap 3.0 by default has a 15px padding on top and bottom, so we just need to override it!

For example:

.navbar-nav > li > a {padding-top:10px !important; padding-bottom:10px !important;}
.navbar {min-height:40px !important}

Don't. Leave them as Java and use IKVM to convert them to .Net DLLs.

Use a CASE statement and do it like this:

SELECT 
    T1.Id [Id]
    ,CASE WHEN T2.Id IS NOT NULL THEN 'TRUE' ELSE 'FALSE' END [Has Foreign Key in T2]
FROM
    TABLE1 [T1]
    LEFT OUTER JOIN
        TABLE2 [T2]
        ON
        T2.Id = T1.Id

By default any files you add to src/main/resources will be included in the jar.

If you need to change that behavior for whatever reason, you can do so by configuring sourceSets.

This part of the documentation has all the details

The overall dimensions of a range are in its Width and Height properties.

Dim r As Range
Set r = ActiveSheet.Range("A4:H12")

Debug.Print r.Width
Debug.Print r.Height

I was facing a similar issue, I had a file on my project, and wanted to test a class which had to deal with loading files from the FS and process them some way. What I did was:

• added the file test.txt to my test project
• on the solution explorer hit alt-enter (file properties)
• there I set BuildAction to Content and Copy to Output Directory to Copy if newer, I guess Copy always would have done it as well

then on my tests I just had to Path.Combine(Environment.CurrentDirectory, "test.txt") and that's it. Whenever the project is compiled it will copy the file (and all it's parent path, in case it was in, say, a folder) to the bin\Debug (or whatever configuration you are using) folder.

You need jackson dependency for this serialization and deserialization.

Add this dependency:

Gradle:

compile("com.fasterxml.jackson.datatype:jackson-datatype-jsr310:2.9.4")

Maven:

<dependency>
    <groupId>com.fasterxml.jackson.datatype</groupId>
    <artifactId>jackson-datatype-jsr310</artifactId>
</dependency>

After that, You need to tell Jackson ObjectMapper to use JavaTimeModule. To do that, Autowire ObjectMapper in the main class and register JavaTimeModule to it.

import javax.annotation.PostConstruct;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.datatype.jsr310.JavaTimeModule;

@SpringBootApplication
public class MockEmployeeApplication {

  @Autowired
  private ObjectMapper objectMapper;

  public static void main(String[] args) {
    SpringApplication.run(MockEmployeeApplication.class, args);

  }

  @PostConstruct
  public void setUp() {
    objectMapper.registerModule(new JavaTimeModule());
  }
}

After that, Your LocalDate and LocalDateTime should be serialized and deserialized correctly.

Yes, it is possible and you have answered it! About good practises, I think it is better to launch commands from files and not directly from your code. So you have to make Java execute the list of commands (or one command) in an existing .bat, .sh , .ksh ... files. Here is an example of executing a list of commands in a file MyFile.sh:

    String[] cmd = { "sh", "MyFile.sh", "\pathOfTheFile"};
    Runtime.getRuntime().exec(cmd);

A break statement results in the termination of the statement to which it applies (switch, for, do, or while).

A continue statement is used to end the current loop iteration and return control to the loop statement.

Most devices have some form of emulated storage. if they support sd cards they are usually mounted to /sdcard (or some variation of that name) which is usually symlinked to to a directory in /storage like /storage/sdcard0 or /storage/0 sometimes the emulated storage is mounted to /sdcard and the actual path is something like /storage/emulated/legacy. You should be able to use to get the downloads directory. You are best off using the api calls to get directories. Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS);

Since the filesystems and sdcard support varies among devices.

see similar question for more info how to access downloads folder in android?

Usually the DownloadManager handles downloads and the files are then accessed by requesting the file's uri fromthe download manager using a file id to get where file was places which would usually be somewhere in the sdcard/ real or emulated since apps can only read data from certain places on the filesystem outside of their data directory like the sdcard

Check the Debug class. http://developer.android.com/reference/android/os/Debug.html i.e. Debug.getNativeHeapAllocatedSize()

It has methods to get the used native heap, which is i.e. used by external bitmaps in your app. For the heap that the app is using internally, you can see that in the DDMS tool that comes with the Android SDK and is also available via Eclipse.

The native heap + the heap as indicated in the DDMS make up the total heap that your app is allocating.

For CPU usage I'm not sure if there's anything available via API/SDK.

go get disables the "terminal prompt" by default. This can be changed by setting an environment variable of git:

    If Not String.IsNullOrEmpty(Address.Groups("e").Value) Then Extension = Address.Groups("e").Value

The regex will attempt to find a result, if there is none, it move to the next alternative. If no result is found, none of the 4 formats where present.

I've achieved this by separating them in different , e.g.:

<div class="table">
  <div class="row">
    <div class="col">TD</div>
    <div class="col">TD</div>
    <div class="col">TD</div>
    <div class="col">TD</div>
    <div class="col">TD</div>
  </div>
</div>
<div class="table">
  <div class="row">
    <div class="col">TD</div>
  </div>
</div>

or you can define different classes for each tables

<div class="table2">
  <div class="row2">
    <div class="col2">TD</div>
  </div>
</div>

From the user point of view they behave identically.

Granted it doesn't solve all colspan/rowspan problems but it does answer my need of the time.

For me it was using {{ }} instead of {% %}:

There is a php library (pdfparser) that does exactly what you want.

project website

http://www.pdfparser.org/

github

https://github.com/smalot/pdfparser

Demo page/api

http://www.pdfparser.org/demo

After including pdfparser in your project you can get all text from mypdf.pdf like so:

<?php
$parser = new \installpath\PdfParser\Parser();
$pdf    = $parser->parseFile('mypdf.pdf');  
$text = $pdf->getText();
echo $text;//all text from mypdf.pdf

?>

Simular you can get the metadata from the pdf as wel as getting the pdf objects (for example images).

Declaring a static variable in Java, means that there will be only one copy, no matter how many objects of the class are created. The variable will be accessible even with no Objects created at all. However, threads may have locally cached values of it.

When a variable is volatile and not static, there will be one variable for each Object. So, on the surface it seems there is no difference from a normal variable but totally different from static. However, even with Object fields, a thread may cache a variable value locally.

This means that if two threads update a variable of the same Object concurrently, and the variable is not declared volatile, there could be a case in which one of the thread has in cache an old value.

Even if you access a static value through multiple threads, each thread can have its local cached copy! To avoid this you can declare the variable as static volatile and this will force the thread to read each time the global value.

However, volatile is not a substitute for proper synchronisation!
For instance:

private static volatile int counter = 0;

private void concurrentMethodWrong() {
  counter = counter + 5;
  //do something
  counter = counter - 5;
}

Executing concurrentMethodWrong concurrently many times may lead to a final value of counter different from zero!
To solve the problem, you have to implement a lock:

private static final Object counterLock = new Object();

private static volatile int counter = 0;

private void concurrentMethodRight() {
  synchronized (counterLock) {
    counter = counter + 5;
  }
  //do something
  synchronized (counterLock) {
    counter = counter - 5;
  }
}

Or use the AtomicInteger class.

PART I: How To Log In

We'll assume you already know how to build a login+password HTML form which POSTs the values to a script on the server side for authentication. The sections below will deal with patterns for sound practical auth, and how to avoid the most common security pitfalls.

To HTTPS or not to HTTPS?

Unless the connection is already secure (that is, tunneled through HTTPS using SSL/TLS), your login form values will be sent in cleartext, which allows anyone eavesdropping on the line between browser and web server will be able to read logins as they pass through. This type of wiretapping is done routinely by governments, but in general, we won't address 'owned' wires other than to say this: Just use HTTPS.

In essence, the only practical way to protect against wiretapping/packet sniffing during login is by using HTTPS or another certificate-based encryption scheme (for example, TLS) or a proven & tested challenge-response scheme (for example, the Diffie-Hellman-based SRP). Any other method can be easily circumvented by an eavesdropping attacker.

Of course, if you are willing to get a little bit impractical, you could also employ some form of two-factor authentication scheme (e.g. the Google Authenticator app, a physical 'cold war style' codebook, or an RSA key generator dongle). If applied correctly, this could work even with an unsecured connection, but it's hard to imagine that a dev would be willing to implement two-factor auth but not SSL.

(Do not) Roll-your-own JavaScript encryption/hashing

Given the perceived (though now avoidable) cost and technical difficulty of setting up an SSL certificate on your website, some developers are tempted to roll their own in-browser hashing or encryption schemes in order to avoid passing cleartext logins over an unsecured wire.

While this is a noble thought, it is essentially useless (and can be a security flaw) unless it is combined with one of the above - that is, either securing the line with strong encryption or using a tried-and-tested challenge-response mechanism (if you don't know what that is, just know that it is one of the most difficult to prove, most difficult to design, and most difficult to implement concepts in digital security).

While it is true that hashing the password can be effective against password disclosure, it is vulnerable to replay attacks, Man-In-The-Middle attacks / hijackings (if an attacker can inject a few bytes into your unsecured HTML page before it reaches your browser, they can simply comment out the hashing in the JavaScript), or brute-force attacks (since you are handing the attacker both username, salt and hashed password).

CAPTCHAS against humanity

CAPTCHA is meant to thwart one specific category of attack: automated dictionary/brute force trial-and-error with no human operator. There is no doubt that this is a real threat, however, there are ways of dealing with it seamlessly that don't require a CAPTCHA, specifically properly designed server-side login throttling schemes - we'll discuss those later.

Know that CAPTCHA implementations are not created alike; they often aren't human-solvable, most of them are actually ineffective against bots, all of them are ineffective against cheap third-world labor (according to OWASP, the current sweatshop rate is $12 per 500 tests), and some implementations may be technically illegal in some countries (see OWASP Authentication Cheat Sheet). If you must use a CAPTCHA, use Google's reCAPTCHA, since it is OCR-hard by definition (since it uses already OCR-misclassified book scans) and tries very hard to be user-friendly.

Personally, I tend to find CAPTCHAS annoying, and use them only as a last resort when a user has failed to log in a number of times and throttling delays are maxed out. This will happen rarely enough to be acceptable, and it strengthens the system as a whole.

Storing Passwords / Verifying logins

This may finally be common knowledge after all the highly-publicized hacks and user data leaks we've seen in recent years, but it has to be said: Do not store passwords in cleartext in your database. User databases are routinely hacked, leaked or gleaned through SQL injection, and if you are storing raw, plaintext passwords, that is instant game over for your login security.

So if you can't store the password, how do you check that the login+password combination POSTed from the login form is correct? The answer is hashing using a key derivation function. Whenever a new user is created or a password is changed, you take the password and run it through a KDF, such as Argon2, bcrypt, scrypt or PBKDF2, turning the cleartext password ("correcthorsebatterystaple") into a long, random-looking string, which is a lot safer to store in your database. To verify a login, you run the same hash function on the entered password, this time passing in the salt and compare the resulting hash string to the value stored in your database. Argon2, bcrypt and scrypt store the salt with the hash already. Check out this article on sec.stackexchange for more detailed information.

The reason a salt is used is that hashing in itself is not sufficient -- you'll want to add a so-called 'salt' to protect the hash against rainbow tables. A salt effectively prevents two passwords that exactly match from being stored as the same hash value, preventing the whole database being scanned in one run if an attacker is executing a password guessing attack.

A cryptographic hash should not be used for password storage because user-selected passwords are not strong enough (i.e. do not usually contain enough entropy) and a password guessing attack could be completed in a relatively short time by an attacker with access to the hashes. This is why KDFs are used - these effectively "stretch the key", which means that every password guess an attacker makes causes multiple repetitions of the hash algorithm, for example 10,000 times, which causes the attacker to guess the password 10,000 times slower.

Session data - "You are logged in as Spiderman69"

Once the server has verified the login and password against your user database and found a match, the system needs a way to remember that the browser has been authenticated. This fact should only ever be stored server side in the session data.

If you are unfamiliar with session data, here's how it works: A single randomly-generated string is stored in an expiring cookie and used to reference a collection of data - the session data - which is stored on the server. If you are using an MVC framework, this is undoubtedly handled already.

If at all possible, make sure the session cookie has the secure and HTTP Only flags set when sent to the browser. The HttpOnly flag provides some protection against the cookie being read through XSS attack. The secure flag ensures that the cookie is only sent back via HTTPS, and therefore protects against network sniffing attacks. The value of the cookie should not be predictable. Where a cookie referencing a non-existent session is presented, its value should be replaced immediately to prevent session fixation.

Session state can also be maintained on the client side. This is achieved by using techniques like JWT (JSON Web Token).

PART II: How To Remain Logged In - The Infamous "Remember Me" Checkbox

Persistent Login Cookies ("remember me" functionality) are a danger zone; on the one hand, they are entirely as safe as conventional logins when users understand how to handle them; and on the other hand, they are an enormous security risk in the hands of careless users, who may use them on public computers and forget to log out, and who may not know what browser cookies are or how to delete them.

Personally, I like persistent logins for the websites I visit on a regular basis, but I know how to handle them safely. If you are positive that your users know the same, you can use persistent logins with a clean conscience. If not - well, then you may subscribe to the philosophy that users who are careless with their login credentials brought it upon themselves if they get hacked. It's not like we go to our user's houses and tear off all those facepalm-inducing Post-It notes with passwords they have lined up on the edge of their monitors, either.

Of course, some systems can't afford to have any accounts hacked; for such systems, there is no way you can justify having persistent logins.

If you DO decide to implement persistent login cookies, this is how you do it:

1. First, take some time to read Paragon Initiative's article on the subject. You'll need to get a bunch of elements right, and the article does a great job of explaining each.

2. And just to reiterate one of the most common pitfalls, DO NOT STORE THE PERSISTENT LOGIN COOKIE (TOKEN) IN YOUR DATABASE, ONLY A HASH OF IT! The login token is Password Equivalent, so if an attacker got their hands on your database, they could use the tokens to log in to any account, just as if they were cleartext login-password combinations. Therefore, use hashing (according to https://security.stackexchange.com/a/63438/5002 a weak hash will do just fine for this purpose) when storing persistent login tokens.

PART III: Using Secret Questions

Don't implement 'secret questions'. The 'secret questions' feature is a security anti-pattern. Read the paper from link number 4 from the MUST-READ list. You can ask Sarah Palin about that one, after her Yahoo! email account got hacked during a previous presidential campaign because the answer to her security question was... "Wasilla High School"!

Even with user-specified questions, it is highly likely that most users will choose either:

• A 'standard' secret question like mother's maiden name or favorite pet

• A simple piece of trivia that anyone could lift from their blog, LinkedIn profile, or similar

• Any question that is easier to answer than guessing their password. Which, for any decent password, is every question you can imagine

In conclusion, security questions are inherently insecure in virtually all their forms and variations, and should not be employed in an authentication scheme for any reason.

The true reason why security questions even exist in the wild is that they conveniently save the cost of a few support calls from users who can't access their email to get to a reactivation code. This at the expense of security and Sarah Palin's reputation. Worth it? Probably not.

PART IV: Forgotten Password Functionality

I already mentioned why you should never use security questions for handling forgotten/lost user passwords; it also goes without saying that you should never e-mail users their actual passwords. There are at least two more all-too-common pitfalls to avoid in this field:

1. Don't reset a forgotten password to an autogenerated strong password - such passwords are notoriously hard to remember, which means the user must either change it or write it down - say, on a bright yellow Post-It on the edge of their monitor. Instead of setting a new password, just let users pick a new one right away - which is what they want to do anyway. (An exception to this might be if the users are universally using a password manager to store/manage passwords that would normally be impossible to remember without writing it down).

2. Always hash the lost password code/token in the database. AGAIN, this code is another example of a Password Equivalent, so it MUST be hashed in case an attacker got their hands on your database. When a lost password code is requested, send the plaintext code to the user's email address, then hash it, save the hash in your database -- and throw away the original. Just like a password or a persistent login token.

A final note: always make sure your interface for entering the 'lost password code' is at least as secure as your login form itself, or an attacker will simply use this to gain access instead. Making sure you generate very long 'lost password codes' (for example, 16 case-sensitive alphanumeric characters) is a good start, but consider adding the same throttling scheme that you do for the login form itself.

PART V: Checking Password Strength

First, you'll want to read this small article for a reality check: The 500 most common passwords

Okay, so maybe the list isn't the canonical list of most common passwords on any system anywhere ever, but it's a good indication of how poorly people will choose their passwords when there is no enforced policy in place. Plus, the list looks frighteningly close to home when you compare it to publicly available analyses of recently stolen passwords.

So: With no minimum password strength requirements, 2% of users use one of the top 20 most common passwords. Meaning: if an attacker gets just 20 attempts, 1 in 50 accounts on your website will be crackable.

Thwarting this requires calculating the entropy of a password and then applying a threshold. The National Institute of Standards and Technology (NIST) Special Publication 800-63 has a set of very good suggestions. That, when combined with a dictionary and keyboard layout analysis (for example, 'qwertyuiop' is a bad password), can reject 99% of all poorly selected passwords at a level of 18 bits of entropy. Simply calculating password strength and showing a visual strength meter to a user is good, but insufficient. Unless it is enforced, a lot of users will most likely ignore it.

And for a refreshing take on user-friendliness of high-entropy passwords, Randall Munroe's Password Strength xkcd is highly recommended.

Utilize Troy Hunt's Have I Been Pwned API to check users passwords against passwords compromised in public data breaches.

PART VI: Much More - Or: Preventing Rapid-Fire Login Attempts

First, have a look at the numbers: Password Recovery Speeds - How long will your password stand up

If you don't have the time to look through the tables in that link, here's the list of them:

1. It takes virtually no time to crack a weak password, even if you're cracking it with an abacus

2. It takes virtually no time to crack an alphanumeric 9-character password if it is case insensitive

3. It takes virtually no time to crack an intricate, symbols-and-letters-and-numbers, upper-and-lowercase password if it is less than 8 characters long (a desktop PC can search the entire keyspace up to 7 characters in a matter of days or even hours)

4. It would, however, take an inordinate amount of time to crack even a 6-character password, if you were limited to one attempt per second!

So what can we learn from these numbers? Well, lots, but we can focus on the most important part: the fact that preventing large numbers of rapid-fire successive login attempts (ie. the brute force attack) really isn't that difficult. But preventing it right isn't as easy as it seems.

Generally speaking, you have three choices that are all effective against brute-force attacks (and dictionary attacks, but since you are already employing a strong passwords policy, they shouldn't be an issue):

• Present a CAPTCHA after N failed attempts (annoying as hell and often ineffective -- but I'm repeating myself here)

• Locking accounts and requiring email verification after N failed attempts (this is a DoS attack waiting to happen)

• And finally, login throttling: that is, setting a time delay between attempts after N failed attempts (yes, DoS attacks are still possible, but at least they are far less likely and a lot more complicated to pull off).

Best practice #1: A short time delay that increases with the number of failed attempts, like:

• 1 failed attempt = no delay
• 2 failed attempts = 2 sec delay
• 3 failed attempts = 4 sec delay
• 4 failed attempts = 8 sec delay
• 5 failed attempts = 16 sec delay
• etc.

DoS attacking this scheme would be very impractical, since the resulting lockout time is slightly larger than the sum of the previous lockout times.

To clarify: The delay is not a delay before returning the response to the browser. It is more like a timeout or refractory period during which login attempts to a specific account or from a specific IP address will not be accepted or evaluated at all. That is, correct credentials will not return in a successful login, and incorrect credentials will not trigger a delay increase.

Best practice #2: A medium length time delay that goes into effect after N failed attempts, like:

• 1-4 failed attempts = no delay
• 5 failed attempts = 15-30 min delay

DoS attacking this scheme would be quite impractical, but certainly doable. Also, it might be relevant to note that such a long delay can be very annoying for a legitimate user. Forgetful users will dislike you.

Best practice #3: Combining the two approaches - either a fixed, short time delay that goes into effect after N failed attempts, like:

• 1-4 failed attempts = no delay
• 5+ failed attempts = 20 sec delay

Or, an increasing delay with a fixed upper bound, like:

• 1 failed attempt = 5 sec delay
• 2 failed attempts = 15 sec delay
• 3+ failed attempts = 45 sec delay

This final scheme was taken from the OWASP best-practices suggestions (link 1 from the MUST-READ list) and should be considered best practice, even if it is admittedly on the restrictive side.

As a rule of thumb, however, I would say: the stronger your password policy is, the less you have to bug users with delays. If you require strong (case-sensitive alphanumerics + required numbers and symbols) 9+ character passwords, you could give the users 2-4 non-delayed password attempts before activating the throttling.

DoS attacking this final login throttling scheme would be very impractical. And as a final touch, always allow persistent (cookie) logins (and/or a CAPTCHA-verified login form) to pass through, so legitimate users won't even be delayed while the attack is in progress. That way, the very impractical DoS attack becomes an extremely impractical attack.

Additionally, it makes sense to do more aggressive throttling on admin accounts, since those are the most attractive entry points

PART VII: Distributed Brute Force Attacks

Just as an aside, more advanced attackers will try to circumvent login throttling by 'spreading their activities':

• Distributing the attempts on a botnet to prevent IP address flagging

• Rather than picking one user and trying the 50.000 most common passwords (which they can't, because of our throttling), they will pick THE most common password and try it against 50.000 users instead. That way, not only do they get around maximum-attempts measures like CAPTCHAs and login throttling, their chance of success increases as well, since the number 1 most common password is far more likely than number 49.995

• Spacing the login requests for each user account, say, 30 seconds apart, to sneak under the radar

Here, the best practice would be logging the number of failed logins, system-wide, and using a running average of your site's bad-login frequency as the basis for an upper limit that you then impose on all users.

Too abstract? Let me rephrase:

Say your site has had an average of 120 bad logins per day over the past 3 months. Using that (running average), your system might set the global limit to 3 times that -- ie. 360 failed attempts over a 24 hour period. Then, if the total number of failed attempts across all accounts exceeds that number within one day (or even better, monitor the rate of acceleration and trigger on a calculated threshold), it activates system-wide login throttling - meaning short delays for ALL users (still, with the exception of cookie logins and/or backup CAPTCHA logins).

I also posted a question with more details and a really good discussion of how to avoid tricky pitfals in fending off distributed brute force attacks

PART VIII: Two-Factor Authentication and Authentication Providers

Credentials can be compromised, whether by exploits, passwords being written down and lost, laptops with keys being stolen, or users entering logins into phishing sites. Logins can be further protected with two-factor authentication, which uses out-of-band factors such as single-use codes received from a phone call, SMS message, app, or dongle. Several providers offer two-factor authentication services.

Authentication can be completely delegated to a single-sign-on service, where another provider handles collecting credentials. This pushes the problem to a trusted third party. Google and Twitter both provide standards-based SSO services, while Facebook provides a similar proprietary solution.

if you're using the compiled bootstrap, one of the ways of fixing it is by editing the bootstrap.min.js before the line

$next[0].offsetWidth 

force reflow Change to

if (typeof $next == 'object' && $next.length) $next[0].offsetWidth // force reflow

Dealing with markup in floats is a non trivial task. In the English/American notation you format one thousand plus 46*10-2:

1,000.46

But in Germany you would change comma and point:

1.000,46

This makes it really hard guessing the right number in multi-language applications.
I strongly suggest using Zend_Measure of the Zend Framework for this task. This component will parse the string to a float by the users language.

Extending Django User Model (UserProfile) like a Pro

I've found this very useful: link

An extract:

from django.contrib.auth.models import User

class Employee(models.Model):
    user = models.OneToOneField(User)
    department = models.CharField(max_length=100)

>>> u = User.objects.get(username='fsmith')
>>> freds_department = u.employee.department

You can try this:

string[] arr = ((IEnumerable)obj).Cast<object>()
                                 .Select(x => x.ToString())
                                 .ToArray();

Once every array implements IEnumerable interface

Here is a full example of a yes/no DialogFragment:

The class:

public class SomeDialog extends DialogFragment {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        return new AlertDialog.Builder(getActivity())
            .setTitle("Title")
            .setMessage("Sure you wanna do this!")
            .setNegativeButton(android.R.string.no, new OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    // do nothing (will close dialog)
                }
            })
            .setPositiveButton(android.R.string.yes,  new OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    // do something
                }
            })
            .create();
    }
}

To start dialog:

        FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
        // Create and show the dialog.
        SomeDialog newFragment = new SomeDialog ();
        newFragment.show(ft, "dialog");

You could also let the class implement onClickListener and use that instead of embedded listeners.

Callback to Activity

If you want to implement callback this is how it is done In your activity:

YourActivity extends Activity implements OnFragmentClickListener

and

@Override
public void onFragmentClick(int action, Object object) {
    switch(action) {
        case SOME_ACTION:
        //Do your action here
        break;
    }
}

The callback class:

public interface OnFragmentClickListener {
    public void onFragmentClick(int action, Object object);
}

Then to perform a callback from a fragment you need to make sure the listener is attached like this:

@Override
public void onAttach(Activity activity) {
    super.onAttach(activity);
    try {
        mListener = (OnFragmentClickListener) activity;
    } catch (ClassCastException e) {
        throw new ClassCastException(activity.toString() + " must implement listeners!");
    }
}

And a callback is performed like this:

mListener.onFragmentClick(SOME_ACTION, null); // null or some important object as second parameter.

Pretty late on the answer, but if you have a TextView that you're showing the phone number in, then you don't need to deal with intents at all, you can just use the XML attribute android:autoLink="phone" and the OS will automatically initiate an ACTION_DIAL Intent.

This should technically be achievable using window.location.reload():

HTML:

<button (click)="refresh()">Refresh</button>

TS:

refresh(): void {
    window.location.reload();
}

Update:

Here is a basic StackBlitz example showing the refresh in action. Notice the URL on "/hello" path is retained when window.location.reload() is executed.

putExtra() : This method sends the data to another activity and in parameter, we have to pass key-value pair.

Syntax: intent.putExtra("key", value);

Eg: intent.putExtra("full_name", "Vishnu Sivan");

Intent intent=getIntent() : It gets the Intent from the previous activity.

fullname = intent.getStringExtra(“full_name”) : This line gets the string form previous activity and in parameter, we have to pass the key which we have mentioned in previous activity.

Sample Code:

Intent intent = new Intent(getApplicationContext(), MainActivity.class);
intent.putExtra("firstName", "Vishnu");
intent.putExtra("lastName", "Sivan");
startActivity(intent);

If you need this code in several places then I'd suggest that you add a short function to keep your code simpler and easier to test.

function add_days( $days, $from_date = null ) {
    if ( is_numeric( $from_date ) ) { 
        $new_date = $from_date; 
    } else { 
        $new_date = time();
    }

    // Timestamp is the number of seconds since an event in the past
    // To increate the value by one day we have to add 86400 seconds to the value
    // 86400 = 24h * 60m * 60s
    $new_date += $days * 86400;

    return $new_date;
}

Then you can use it anywhere like this:

$today       = add_days( 0 );
$tomorrow    = add_days( 1 );
$yesterday   = add_days( -1 );
$in_36_hours = add_days( 1.5 );

$first_reminder  = add_days( 10 );
$second_reminder = add_days( 5, $first_reminder );
$last_reminder   = add_days( 3, $second_reminder );

The integer is being converted into a string rather than vice-versa. You want:

var newValue = parseInt(currentValue) + 1

Here's what I did. I had the same problem and ended up searching the web for resources for hours.

<style type="text/css">
   html, body, div, iframe { margin:0; padding:0; height:100%; }
   iframe { position:fixed; display:block; width:100%; border:none; }
</style>

I added this to the head section.

Please note that my iframe is located inside the middle cell of a table that has 3 rows and 1 column.

I created a base class for creating string-valued enums in .NET. It is just one C# file that you can copy & paste into your projects, or install via NuGet package named StringEnum.

Usage:

///<completionlist cref="HexColor"/> 
class HexColor : StringEnum<HexColor>
{
    public static readonly HexColor Blue = New("#FF0000");
    public static readonly HexColor Green = New("#00FF00");
    public static readonly HexColor Red = New("#000FF");
}

Features

• Your StringEnum looks somewhat similar to a regular enum:

    // Static Parse Method
    HexColor.Parse("#FF0000") // => HexColor.Red
    HexColor.Parse("#ff0000", caseSensitive: false) // => HexColor.Red
    HexColor.Parse("invalid") // => throws InvalidOperationException

    // Static TryParse method.
    HexColor.TryParse("#FF0000") // => HexColor.Red
    HexColor.TryParse("#ff0000", caseSensitive: false) // => HexColor.Red
    HexColor.TryParse("invalid") // => null

    // Parse and TryParse returns the preexistent instances
    object.ReferenceEquals(HexColor.Parse("#FF0000"), HexColor.Red) // => true

    // Conversion from your `StringEnum` to `string`
    string myString1 = HexColor.Red.ToString(); // => "#FF0000"
    string myString2 = HexColor.Red; // => "#FF0000" (implicit cast)

• Intellisense will suggest the enum name if the class is annotated with the xml comment <completitionlist>. (Works in both C# and VB): i.e.

Instalation

Either:

• Install latest StringEnum NuGet package, which is based on .Net Standard 1.0 so it runs on .Net Core >= 1.0, .Net Framework >= 4.5, Mono >= 4.6, etc.
• Or paste the following StringEnum base class to your project. (latest version)

    public abstract class StringEnum<T> : IEquatable<T> where T : StringEnum<T>, new()
    {
        protected string Value;
        private static IList<T> valueList = new List<T>();
        protected static T New(string value)
        {
            if (value == null)
                return null; // the null-valued instance is null.

            var result = new T() { Value = value };
            valueList.Add(result);
            return result;
        }

        public static implicit operator string(StringEnum<T> enumValue) => enumValue.Value;
        public override string ToString() => Value;

        public static bool operator !=(StringEnum<T> o1, StringEnum<T> o2) => o1?.Value != o2?.Value;
        public static bool operator ==(StringEnum<T> o1, StringEnum<T> o2) => o1?.Value == o2?.Value;

        public override bool Equals(object other) => this.Value.Equals((other as T)?.Value ?? (other as string));
        bool IEquatable<T>.Equals(T other) => this.Value.Equals(other.Value);
        public override int GetHashCode() => Value.GetHashCode();

        /// <summary>
        /// Parse the <paramref name="value"/> specified and returns a valid <typeparamref name="T"/> or else throws InvalidOperationException.
        /// </summary>
        /// <param name="value">The string value representad by an instance of <typeparamref name="T"/>. Matches by string value, not by the member name.</param>
        /// <param name="caseSensitive">If true, the strings must match case sensitivity.</param>
        public static T Parse(string value, bool caseSensitive = false)
        {
            var result = TryParse(value, caseSensitive);
            if (result == null)
                throw new InvalidOperationException((value == null ? "null" : $"'{value}'") + $" is not a valid {typeof(T).Name}");

            return result;
        }

        /// <summary>
        /// Parse the <paramref name="value"/> specified and returns a valid <typeparamref name="T"/> or else returns null.
        /// </summary>

        /// <param name="caseSensitive">If true, the strings must match case sensitivity.</param>
        public static T TryParse(string value, bool caseSensitive = false)
        {
            if (value == null) return null;
            if (valueList.Count == 0) System.Runtime.CompilerServices.RuntimeHelpers.RunClassConstructor(typeof(T).TypeHandle); // force static fields initialization
            var field = valueList.FirstOrDefault(f => f.Value.Equals(value,
                    caseSensitive ? StringComparison.Ordinal
                                  : StringComparison.OrdinalIgnoreCase));
            // Not using InvariantCulture because it's only supported in NETStandard >= 2.0

            if (field == null)
                return null;

            return field;
        }
    }

• For Newtonsoft.Json serialization support, copy this extended version instead. StringEnum.cs

I realized after the fact that this code is similar to Ben's answer. I sincerely wrote it from scratch. However I think it has a few extras, like the <completitionlist> hack, the resulting class looks more like an Enum, no use of reflection on Parse(), the NuGet package and repo where I will hopefully address incoming issues and feedback.

IIS 6.0 and previous versions :

ASP.NET integrated with IIS via an ISAPI extension, a C API ( C Programming language based API ) and exposed its own application and request processing model.

This effectively exposed two separate server( request / response ) pipelines, one for native ISAPI filters and extension components, and another for managed application components. ASP.NET components would execute entirely inside the ASP.NET ISAPI extension bubble AND ONLY for requests mapped to ASP.NET in the IIS script map configuration.

Requests to non ASP.NET content types:- images, text files, HTML pages, and script-less ASP pages, were processed by IIS or other ISAPI extensions and were NOT visible to ASP.NET.

The major limitation of this model was that services provided by ASP.NET modules and custom ASP.NET application code were NOT available to non ASP.NET requests

What's a SCRIPT MAP ?

Script maps are used to associate file extensions with the ISAPI handler that executes when that file type is requested. The script map also has an optional setting that verifies that the physical file associated with the request exists before allowing the request to be processed

A good example can be seen here

IIS 7 and above

IIS 7.0 and above have been re-engineered from the ground up to provide a brand new C++ API based ISAPI.

IIS 7.0 and above integrates the ASP.NET runtime with the core functionality of the Web Server, providing a unified(single) request processing pipeline that is exposed to both native and managed components known as modules ( IHttpModules )

What this means is that IIS 7 processes requests that arrive for any content type, with both NON ASP.NET Modules / native IIS modules and ASP.NET modules providing request processing in all stages This is the reason why NON ASP.NET content types (.html, static files ) can be handled by .NET modules.

• You can build new managed modules (IHttpModule) that have the ability to execute for all application content, and provided an enhanced set of request processing services to your application.
• Add new managed Handlers ( IHttpHandler)

<audio id="audio" style="display:none;" src="mp3/Fans-Mi-tooXclusive_com.mp3" controls autoplay loop onloadeddata="setHalfVolume()">

This auto-plays, hides the music and reduces the music even if system volume is high to avoid noise. Place this in script:

<script>
    function setHalfVolume() {
        var myAudio = document.getElementById("audio");
        myAudio.volume = 0.2;
    }
</script>

Surprised a solution using flexbox hasn't been posted yet.

Here's my solution using display: flex and a basic use of :after (thanks to Luggage) to maintain the alignment even with the scrollbar padding the tbody a bit. This has been verified in Chrome 45, Firefox 39, and MS Edge. It can be modified with prefixed properties to work in IE11, and further in IE10 with a CSS hack and the 2012 flexbox syntax.

Note the table width can be modified; this even works at 100% width.

The only caveat is that all table cells must have the same width. Below is a clearly contrived example, but this works fine when cell contents vary (table cells all have the same width and word wrapping on, forcing flexbox to keep them the same width regardless of content). Here is an example where cell contents are different.

Just apply the .scroll class to a table you want scrollable, and make sure it has a thead:

.scroll {_x000D_
  border: 0;_x000D_
  border-collapse: collapse;_x000D_
}_x000D_
_x000D_
.scroll tr {_x000D_
  display: flex;_x000D_
}_x000D_
_x000D_
.scroll td {_x000D_
  padding: 3px;_x000D_
  flex: 1 auto;_x000D_
  border: 1px solid #aaa;_x000D_
  width: 1px;_x000D_
  word-wrap: break-word;_x000D_
}_x000D_
_x000D_
.scroll thead tr:after {_x000D_
  content: '';_x000D_
  overflow-y: scroll;_x000D_
  visibility: hidden;_x000D_
  height: 0;_x000D_
}_x000D_
_x000D_
.scroll thead th {_x000D_
  flex: 1 auto;_x000D_
  display: block;_x000D_
  border: 1px solid #000;_x000D_
}_x000D_
_x000D_
.scroll tbody {_x000D_
  display: block;_x000D_
  width: 100%;_x000D_
  overflow-y: auto;_x000D_

This is a stronger regex replace that won't replace %% that are already doubled in the input.

str = str.replaceAll("(?:[^%]|\\A)%(?:[^%]|\\z)", "%%");

By default you can't use PHP in HTML pages.

To do that, modify your .htacccess file with the following:

AddType application/x-httpd-php .html

This works on IE7+, is standards compliant, and allows differing heights.

<style>
dt {
    float: left;
    clear: left;
    width: 100px;        
    padding: 5px 0;
    margin:0;
}
dd {
    float: left;
    width: 200px;
    padding: 5px 0;
    margin:0;
}
.cf:after {
    content:'';
    display:table;
    clear:both;
}
</style>

<dl class="cf">
    <dt>A</dt>
    <dd>Apple</dd>
    <dt>B</dt>
    <dd>Banana<br>Bread<br>Bun</dd>
    <dt>C</dt>
    <dd>Cinnamon</dd>
</dl>        

See the JSFiddle.

I had the same issue. It's solved by adding following lines in .bashrc:

export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
export HADOOP_OPTS="-Djava.library.path=$HADOOP_HOME/lib"

FYI - if you are importing a List into a JSP, chances are pretty good that you are violating MVC principles. Take a few hours now to read up on the MVC approach to web app development (including use of taglibs) - do some more googling on the subject, it's fascinating and will definitely help you write better apps.

If you are doing anything more complicated than a single JSP displaying some database results, please consider using a framework like Spring, Grails, etc... It will absolutely take you a bit more effort to get going, but it will save you so much time and effort down the road that I really recommend it. Besides, it's cool stuff :-)

I could not get this to work based off the best answer, probably because I'm such a PC noob and missing something obvious. But just FYI in case it helps someone as challenged as me, what has FINALLY worked was through one of the links here (referenced in the answers). This involved simply pasting the following to my .bash_profile:

env=~/.ssh/agent.env

agent_load_env () { test -f "$env" && . "$env" >| /dev/null ; }

agent_start () {
    (umask 077; ssh-agent >| "$env")
    . "$env" >| /dev/null ; }

agent_load_env

# agent_run_state: 0=agent running w/ key; 1=agent w/o key; 2= agent not running
agent_run_state=$(ssh-add -l >| /dev/null 2>&1; echo $?)

if [ ! "$SSH_AUTH_SOCK" ] || [ $agent_run_state = 2 ]; then
    agent_start
    ssh-add
elif [ "$SSH_AUTH_SOCK" ] && [ $agent_run_state = 1 ]; then
    ssh-add
fi

unset env

I probably have something configured weird, but was not successful when I added it to my .profile or .bashrc. The other real challenge I've run into is I'm not an admin on this computer and can't change the environment variables without getting it approved by IT, so this is a solution for those that can't access that.

You know it's working if you're prompted for your ssh password when you open git bash. Hallelujah something finally worked.

This technique is usually used for multiple axis in a figure. In this context it is often required to have a colorbar that corresponds in size with the result from imshow. This can be achieved easily with the axes grid tool kit:

import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable

data = np.arange(100, 0, -1).reshape(10, 10)

fig, ax = plt.subplots()
divider = make_axes_locatable(ax)
cax = divider.append_axes('right', size='5%', pad=0.05)

im = ax.imshow(data, cmap='bone')

fig.colorbar(im, cax=cax, orientation='vertical')
plt.show()

here is the solution

Put your html and css in your /assets/ folder, then load the html file like so:

    WebView wv = new WebView(this);

    wv.loadUrl("file:///android_asset/yourHtml.html");

then in your html you can reference your css in the usual way

<link rel="stylesheet" type="text/css" href="main.css" />

I would Suggest that you do the folllowing,

The enitre project for export and import can be found at https://github.com/tazotodua/useful-php-scripts.

$.each($('input[type=number]'),function(){
  alert($(this).val());
});

This will alert the value of input type number fields

Demo is present at http://jsfiddle.net/2dJAN/33/

my 2 cents:

$('#theDiv').prepend($('<img>',{id:'theImg',src:'theImg.png'}))

The official way to find out if you have 4.5 installed (and not 4.0) is in the registry keys :

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full

Relesae DWORD needs to be bigger than 378675 Here is the Microsoft doc for it

all the other answers of checking the minor version after 4.0.30319.xxxxx seem correct though (msbuild.exe -version , or properties of clr.dll), i just needed something documented (not a blog)

The correct syntax is window.open(URL,WindowTitle,'_blank') All the arguments in the open must be strings. They are not mandatory, and window can be dropped. So just newWin=open() works as well, if you plan to populate newWin.document by yourself. BUT you MUST use all the three arguments, and the third one set to '_blank' for opening a new true window and not a tab.

Use ifstream to read data from a file:

std::ifstream input( "filename.ext" );

If you really need to read line by line, then do this:

for( std::string line; getline( input, line ); )
{
    ...for each line in input...
}

But you probably just need to extract coordinate pairs:

int x, y;
input >> x >> y;

Update:

In your code you use ofstream myfile;, however the o in ofstream stands for output. If you want to read from the file (input) use ifstream. If you want to both read and write use fstream.
