Here is the reason. Starting from Jersey 2.26, Jersey removed HK2 as a hard dependency. It created an SPI as a facade for the dependency injection provider, in the form of the InjectionManager and InjectionManagerFactory. So for Jersey to run, we need to have an implementation of the InjectionManagerFactory. There are two implementations of this, which are for HK2 and CDI. The HK2 dependency is the jersey-hk2 others are talking about.

<dependency>
    <groupId>org.glassfish.jersey.inject</groupId>
    <artifactId>jersey-hk2</artifactId>
    <version>2.26</version>
</dependency>

The CDI dependency is

<dependency>
    <groupId>org.glassfish.jersey.inject</groupId>
    <artifactId>jersey-cdi2-se</artifactId>
    <version>2.26</version>
</dependency>

This (jersey-cdi2-se) should only be used for SE environments and not EE environments.

Jersey made this change to allow others to provide their own dependency injection framework. They don't have any plans to implement any other InjectionManagers, though others have made attempts at implementing one for Guice.

curl is a command in linux (and a library in php). Curl typically makes an HTTP request.

What you really want to do is make an HTTP (or XHR) request from javascript.

Using this vocab you'll find a bunch of examples, for starters: Sending authorization headers with jquery and ajax

Essentially you will want to call $.ajax with a few options for the header, etc.

$.ajax({
        url: 'https://api.wit.ai/message?v=20140826&q=',
        beforeSend: function(xhr) {
             xhr.setRequestHeader("Authorization", "Bearer 6QXNMEMFHNY4FJ5ELNFMP5KRW52WFXN5")
        }, success: function(data){
            alert(data);
            //process the JSON data etc
        }
})

I had a similar issue before even with this approach df.loc[:,'industry'] = 'yyy', but once I refreshed the notebook, it ran well.

You may want to try refreshing the cells after you have df.loc[:,'industry'] = 'yyy'.

The easiest way to compute the correct mouse click or mouse move position on a canvas event is to use this little equation:

canvas.addEventListener('click', event =>
{
    let bound = canvas.getBoundingClientRect();

    let x = event.clientX - bound.left - canvas.clientLeft;
    let y = event.clientY - bound.top - canvas.clientTop;

    context.fillRect(x, y, 16, 16);
});

If the canvas has padding-left or padding-top, subtract x and y via:

x -= parseFloat(style['padding-left'].replace('px'));
y -= parseFloat(style['padding-top'].replace('px'));

If what you want is to have the print operation automatically change floats to only show 2 decimal places, consider writing a function to replace 'print'. For instance:

def fp(*args):  # fp means 'floating print'
    tmps = []
    for arg in args:
        if type(arg) is float: arg = round(arg, 2)  # transform only floats
        tmps.append(str(arg))
    print(" ".join(tmps)

Use fp() in place of print ...

fp("PI is", 3.14159) ... instead of ... print "PI is", 3.14159

Linux supports capabilities to support more fine-grained permissions than just "this application is run as root". One of those capabilities is CAP_NET_BIND_SERVICE which is about binding to a privileged port (<1024).

Unfortunately I don't know how to exploit that to run an application as non-root while still giving it CAP_NET_BIND_SERVICE (probably using setcap, but there's bound to be an existing solution for this).

float RandomFloat(float min, float max)
{
    float r = (float)rand() / (float)RAND_MAX;
    return min + r * (max - min);
}

Is this what you are looking for? Here is a fiddle demo.

The layout is based on percentage, colors are for clarity. If the content column overflows, a scrollbar should appear.

body, html, .container-fluid {
  height: 100%;
}

.navbar {
  width:100%;
  background:yellow;
}

.article-tree {
  height:100%;
  width: 25%;
  float:left;
  background: pink;
}

.content-area {
  overflow: auto;
  height: 100%;
  background:orange;
}

.footer {
   background: red;
   width:100%;
   height: 20px;
}

You can also use svg instead of an image map. ;)

There is a tutorial on how to do this.

Trying to make some order:

it all works - all but the firefox bookmarking function. for some reason the 'window.sidebar.addPanel' is not a function for the debugger, though it is working fine.

The problem is that it takes its values from the calling <a ..> tag: title as the bookmark name and href as the bookmark address. so this is my code:

javascript:

$("#bookmarkme").click(function () {
  var url = 'http://' + location.host; // i'm in a sub-page and bookmarking the home page
  var name = "Snir's Homepage";

  if (navigator.userAgent.toLowerCase().indexOf('chrome') > -1){ //chrome
    alert("In order to bookmark go to the homepage and press " 
        + (navigator.userAgent.toLowerCase().indexOf('mac') != -1 ? 
            'Command/Cmd' : 'CTRL') + "+D.")
  } 
  else if (window.sidebar) { // Mozilla Firefox Bookmark
    //important for firefox to add bookmarks - remember to check out the checkbox on the popup
    $(this).attr('rel', 'sidebar');
    //set the appropriate attributes
    $(this).attr('href', url);
    $(this).attr('title', name);

    //add bookmark:
    //  window.sidebar.addPanel(name, url, '');
    //  window.sidebar.addPanel(url, name, '');
    window.sidebar.addPanel('', '', '');
  } 
  else if (window.external) { // IE Favorite
        window.external.addFavorite(url, name);
  } 
  return;
});

html:

  <a id="bookmarkme" href="#" title="bookmark this page">Bookmark This Page</a>

In internet explorer there is a different between 'addFavorite': <a href="javascript:window.external.addFavorite('http://tiny.cc/snir','snir-site')">..</a> and 'AddFavorite': <span onclick="window.external.AddFavorite(location.href, document.title);">..</span>.

example here: http://www.yourhtmlsource.com/javascript/addtofavorites.html

Important, in chrome we can't add bookmarks using js (aspnet-i): http://www.codeproject.com/Questions/452899/How-to-add-bookmark-in-Google-Chrome-Opera-and-Saf

You can just modified the .bash_profile by adding the MySQL $PATH as the following:
export PATH=$PATH:/usr/local/mysql/bin.

I did the following:

1- Open Terminal then $ nano .bash_profile or $ vim .bash_profile

2- Add the following PATH code to the .bash_profile

# Set architecture flags
export ARCHFLAGS="-arch x86_64"
# Ensure user-installed binaries take precedence
export PATH=/usr/local/mysql/bin:$PATH
# Load .bashrc if it exists
test -f ~/.bashrc && source ~/.bashrc 

3- Save the file.

4- Refresh Terminal using $ source ~/.bash_profile

5- To verify, type in Terminal $ mysql --version

6- It should print the output something like this:

$ mysql Ver 14.14 Distrib 5.7.17, for macos10.12 (x86_64)

The Terminal is now configured to read the MySQL commands from $PATH which is placed in the .bash_profile .

This question is old, but is missing some benchmarks. I benchmarked JOIN against its 2 competitors:

• N+1 queries
• 2 queries, the second one using a WHERE IN(...) or equivalent

The result is clear: on MySQL, JOIN is much faster. N+1 queries can drop the performance of an application drastically:

That is, unless you select a lot of records that point to a very small number of distinct, foreign records. Here is a benchmark for the extreme case:

This is very unlikely to happen in a typical application, unless you're joining a -to-many relationship, in which case the foreign key is on the other table, and you're duplicating the main table data many times.

Takeaway:

• For *-to-one relationships, always use JOIN
• For *-to-many relationships, a second query might be faster

See my article on Medium for more information.

look like this demo:

DECLARE @vTable TABLE (IdRow int not null primary key identity(1,1),ValueRow int);

-------Initialize---------
insert into @vTable select 345;
insert into @vTable select 795;
insert into @vTable select 565;
---------------------------

DECLARE @cnt int = 1;
DECLARE @max int = (SELECT MAX(IdRow) FROM @vTable);

WHILE @cnt <= @max
BEGIN
    DECLARE @tempValueRow int = (Select ValueRow FROM @vTable WHERE IdRow = @cnt);

    ---work demo----
    print '@tempValueRow:' + convert(varchar(10),@tempValueRow);
    print '@cnt:' + convert(varchar(10),@cnt);
    print'';
    --------------

    set @cnt = @cnt+1;
END

Version without idRow, using ROW_NUMBER

    DECLARE @vTable TABLE (ValueRow int);
-------Initialize---------
insert into @vTable select 345;
insert into @vTable select 795;
insert into @vTable select 565;
---------------------------

DECLARE @cnt int = 1;
DECLARE @max int = (select count(*) from @vTable);

WHILE @cnt <= @max
BEGIN
    DECLARE @tempValueRow int = (
        select ValueRow 
        from (select ValueRow
            , ROW_NUMBER() OVER(ORDER BY (select 1)) as RowId 
            from @vTable
        ) T1 
    where t1.RowId = @cnt
    );

    ---work demo----
    print '@tempValueRow:' + convert(varchar(10),@tempValueRow);
    print '@cnt:' + convert(varchar(10),@cnt);
    print'';
    --------------

    set @cnt = @cnt+1;
END

For Android API level of 8.0.0, you should use

WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY

instead of

LayoutParams.TYPE_TOAST or TYPE_APPLICATION_PANEL

or SYSTEM_ALERT.

The Java way to do what you want is to use the ServiceLoader mechanism.

Also many people roll their own by having a file in a well known classpath location (i.e. /META-INF/services/myplugin.properties) and then using ClassLoader.getResources() to enumerate all files with this name from all jars. This allows each jar to export its own providers and you can instantiate them by reflection using Class.forName()

As far as .net languages go, VS is hard to beat.

I have used SharpDevelop before for .net, and is overall pretty good.

For other languages like Java, Eclipse is really good, as well as some of the Eclipse variants like Aptana for web work.

Then there's always notepad...

function showPanel(fieldName) {
  var fieldNameElement = document.getElementById("field_name");
  while(fieldNameElement.childNodes.length >= 1) {
    fieldNameElement.removeChild(fieldNameElement.firstChild);
  }
  fieldNameElement.appendChild(fieldNameElement.ownerDocument.createTextNode(fieldName));
}

The advantages of doing it this way:

1. It only uses the DOM, so the technique is portable to other languages, and doesn't rely on the non-standard innerHTML
2. fieldName might contain HTML, which could be an attempted XSS attack. If we know it's just text, we should be creating a text node, instead of having the browser parse it for HTML

If I were going to use a javascript library, I'd use jQuery, and do this:

  $("div#field_name").text(fieldName);

Note that @AnthonyWJones' comment is correct: "field_name" isn't a particularly descriptive id or variable name.

It depends on what you want to do.

ref: http://www.csharp-examples.net/get-files-from-directory/

This will bring back ALL the files in the specified directory

string[] fileArray = Directory.GetFiles(@"c:\Dir\");

This will bring back ALL the files in the specified directory with a certain extension

string[] fileArray = Directory.GetFiles(@"c:\Dir\", "*.jpg");

This will bring back ALL the files in the specified directory AS WELL AS all subdirectories with a certain extension

string[] fileArray = Directory.GetFiles(@"c:\Dir\", "*.jpg", SearchOption.AllDirectories);

Hope this helps

Best practice: one form per product is definitely the way to go.

Benefits:

• It will save you the hassle of having to parse the data to figure out which product was clicked
• It will reduce the size of data being posted

In your specific situation

If you only ever intend to have one form element, in this case a submit button, one form for all should work just fine.

My recommendation Do one form per product, and change your markup to something like:

<form method="post" action="">
    <input type="hidden" name="product_id" value="123">
    <button type="submit" name="action" value="add_to_cart">Add to Cart</button>
</form>

This will give you a much cleaner and usable POST. No parsing. And it will allow you to add more parameters in the future (size, color, quantity, etc).

Note: There's no technical benefit to using <button> vs. <input>, but as a programmer I find it cooler to work with action=='add_to_cart' than action=='Add to Cart'. Besides, I hate mixing presentation with logic. If one day you decide that it makes more sense for the button to say "Add" or if you want to use different languages, you could do so freely without having to worry about your back-end code.

The top answers by Paul H and J. Li do not work for all types of seaborn figures. For the FacetGrid type (for instance sns.lmplot()), use the size and aspect parameter.

Size changes both the height and width, maintaining the aspect ratio.

Aspect only changes the width, keeping the height constant.

You can always get your desired size by playing with these two parameters.

I was having a problem fetching profile photos while using CURL. I thought for a while there was something wrong my implementation of the Facebook API, but I need to add a bit to my CURL called:

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

From emscripten:

function stringToUTF8Array(str, outU8Array, outIdx, maxBytesToWrite) {
  if (!(maxBytesToWrite > 0)) return 0;
  var startIdx = outIdx;
  var endIdx = outIdx + maxBytesToWrite - 1;
  for (var i = 0; i < str.length; ++i) {
    var u = str.charCodeAt(i);
    if (u >= 55296 && u <= 57343) {
      var u1 = str.charCodeAt(++i);
      u = 65536 + ((u & 1023) << 10) | u1 & 1023
    }
    if (u <= 127) {
      if (outIdx >= endIdx) break;
      outU8Array[outIdx++] = u
    } else if (u <= 2047) {
      if (outIdx + 1 >= endIdx) break;
      outU8Array[outIdx++] = 192 | u >> 6;
      outU8Array[outIdx++] = 128 | u & 63
    } else if (u <= 65535) {
      if (outIdx + 2 >= endIdx) break;
      outU8Array[outIdx++] = 224 | u >> 12;
      outU8Array[outIdx++] = 128 | u >> 6 & 63;
      outU8Array[outIdx++] = 128 | u & 63
    } else {
      if (outIdx + 3 >= endIdx) break;
      outU8Array[outIdx++] = 240 | u >> 18;
      outU8Array[outIdx++] = 128 | u >> 12 & 63;
      outU8Array[outIdx++] = 128 | u >> 6 & 63;
      outU8Array[outIdx++] = 128 | u & 63
    }
  }
  outU8Array[outIdx] = 0;
  return outIdx - startIdx
}

Use like:

stringToUTF8Array('abs', new Uint8Array(3), 0, 4);

sender refers to the object that invoked the event that fired the event handler. This is useful if you have many objects using the same event handler.

EventArgs is something of a dummy base class. In and of itself it's more or less useless, but if you derive from it, you can add whatever data you need to pass to your event handlers.

When you implement your own events, use an EventHandler or EventHandler<T> as their type. This guarantees that you'll have exactly these two parameters for all your events (which is a good thing).

You might want to chek if the hard disk is full (df on the console), that's what ultimately triggered this error for me.

Cast the dtype of the col to str and you can perform vectorised slicing calling str:

In [29]:
df['new_col'] = df['First'].astype(str).str[0]
df

Out[29]:
   First  Second new_col
0    123     234       1
1     22    4353       2
2     32     355       3
3    453     453       4
4     45     345       4
5    453     453       4
6     56      56       5

if you need to you can cast the dtype back again calling astype(int) on the column

On Ubuntu with OpenJDK, it installed in /usr/lib/jvm/default-java/jre/lib/ext/jfxrt.jar (technically its a symlink to /usr/share/java/openjfx/jre/lib/ext/jfxrt.jar, but it is probably better to use the default-java link)

This is working for me

$('.Count').each(function () {
    $(this).prop('Counter',0).animate({
        Counter: $(this).text()
    }, {
        duration: 4000,
        easing: 'swing',
        step: function (now) {
            $(this).text(Math.ceil(now));
        }
    });
});

Another trick is to use

.class {
position: absolute;
visibility:hidden;
display:none;
}

This is not likely to mess up your flow (because it takes it out of flow) and makes sure that the user can't see it, and then if display:none works later on it will be working. Keep in mind that visibility:hidden may not remove it from screen readers.

The following is a minimal example that will look like the following image.

Start with an empty activity. You will perform the following tasks to add the RecyclerView. All you need to do is copy and paste the code in each section. Later you can customize it to fit your needs.

• Add dependencies to gradle
• Add the xml layout files for the activity and for the RecyclerView row
• Make the RecyclerView adapter
• Initialize the RecyclerView in your activity

Update Gradle dependencies

Make sure the following dependencies are in your app gradle.build file:

implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:recyclerview-v7:28.0.0'

You can update the version numbers to whatever is the most current. Use compile rather than implementation if you are still using Android Studio 2.x.

Create activity layout

Add the RecyclerView to your xml layout.

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/rvAnimals"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

</RelativeLayout>

Create row layout

Each row in our RecyclerView is only going to have a single TextView. Create a new layout resource file.

recyclerview_row.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:padding="10dp">

    <TextView
        android:id="@+id/tvAnimalName"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="20sp"/>

</LinearLayout>

Create the adapter

The RecyclerView needs an adapter to populate the views in each row with your data. Create a new java file.

MyRecyclerViewAdapter.java

public class MyRecyclerViewAdapter extends RecyclerView.Adapter<MyRecyclerViewAdapter.ViewHolder> {

    private List<String> mData;
    private LayoutInflater mInflater;
    private ItemClickListener mClickListener;

    // data is passed into the constructor
    MyRecyclerViewAdapter(Context context, List<String> data) {
        this.mInflater = LayoutInflater.from(context);
        this.mData = data;
    }

    // inflates the row layout from xml when needed
    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = mInflater.inflate(R.layout.recyclerview_row, parent, false);
        return new ViewHolder(view);
    }

    // binds the data to the TextView in each row
    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        String animal = mData.get(position);
        holder.myTextView.setText(animal);
    }

    // total number of rows
    @Override
    public int getItemCount() {
        return mData.size();
    }


    // stores and recycles views as they are scrolled off screen
    public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
        TextView myTextView;

        ViewHolder(View itemView) {
            super(itemView);
            myTextView = itemView.findViewById(R.id.tvAnimalName);
            itemView.setOnClickListener(this);
        }

        @Override
        public void onClick(View view) {
            if (mClickListener != null) mClickListener.onItemClick(view, getAdapterPosition());
        }
    }

    // convenience method for getting data at click position
    String getItem(int id) {
        return mData.get(id);
    }

    // allows clicks events to be caught
    void setClickListener(ItemClickListener itemClickListener) {
        this.mClickListener = itemClickListener;
    }

    // parent activity will implement this method to respond to click events
    public interface ItemClickListener {
        void onItemClick(View view, int position);
    }
}

Notes

• Although not strictly necessary, I included the functionality for listening for click events on the rows. This was available in the old ListViews and is a common need. You can remove this code if you don't need it.

Initialize RecyclerView in Activity

Add the following code to your main activity.

MainActivity.java

public class MainActivity extends AppCompatActivity implements MyRecyclerViewAdapter.ItemClickListener {

    MyRecyclerViewAdapter adapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // data to populate the RecyclerView with
        ArrayList<String> animalNames = new ArrayList<>();
        animalNames.add("Horse");
        animalNames.add("Cow");
        animalNames.add("Camel");
        animalNames.add("Sheep");
        animalNames.add("Goat");

        // set up the RecyclerView
        RecyclerView recyclerView = findViewById(R.id.rvAnimals);
        recyclerView.setLayoutManager(new LinearLayoutManager(this));
        adapter = new MyRecyclerViewAdapter(this, animalNames);
        adapter.setClickListener(this);
        recyclerView.setAdapter(adapter);
    }

    @Override
    public void onItemClick(View view, int position) {
        Toast.makeText(this, "You clicked " + adapter.getItem(position) + " on row number " + position, Toast.LENGTH_SHORT).show();
    }
}

Notes

• Notice that the activity implements the ItemClickListener that we defined in our adapter. This allows us to handle row click events in onItemClick.

Finished

That's it. You should be able to run your project now and get something similar to the image at the top.

Going on

Adding a divider between rows

You can add a simple divider like this

DividerItemDecoration dividerItemDecoration = new DividerItemDecoration(recyclerView.getContext(),

Pass the object:

doSomething(this)

You can get all data from object:

function(obj){
    var value = obj.value;
    var id = obj.id;
}

Or pass the id only:

doSomething(this.id)

Get the object and after that value:

function(id){
    var value = document.getElementById(id).value;  
}

First of All Theory

1. Big O = Upper Limit O(n)

2. Theta = Order Function - theta(n)

3. Omega = Q-Notation(Lower Limit) Q(n)

Why People Are so Confused?

In many Blogs & Books How this Statement is emphasised is Like

"This is Big O(n^3)" etc.

and people often Confuse like weather

O(n) == theta(n) == Q(n)

But What Worth keeping in mind is They Are Just Mathematical Function With Names O, Theta & Omega

so they have same General Formula of Polynomial,

Let,

f(n) = 2n4 + 100n2 + 10n + 50 then,

g(n) = n4, So g(n) is Function which Take function as Input and returns Variable with Biggerst Power,

Same f(n) & g(n) for Below all explainations

Big O - Function (Provides Upper Bound)

Big O(n4) = 3n4, Because 3n4 > 2n4

3n4 is value of Big O(n4) Just like f(x) = 3x

n4 is playing a role of x here so,

Replacing n4 with x'so, Big O(x') = 2x', Now we both are happy General Concept is

So 0 = f(n) = O(x')

O(x') = cg(n) = 3n4

Putting Value,

0 = 2n4 + 100n2 + 10n + 50 = 3n4

3n4 is our Upper Bound

Theta(n) Provides Lower Bound

Theta(n4) = cg(n) = 2n4 Because 2n4 = Our Example f(n)

2n4 is Value of Theta(n4)

so, 0 = cg(n) = f(n)

0 = 2n4 = 2n4 + 100n2 + 10n + 50

2n4 is our Lower Bound

Omega n - Order Function

This is Calculated to find out that weather lower Bound is similar to Upper bound,

Case 1). Upper Bound is Similar to Lower Bound

if Upper Bound is Similar to Lower Bound, The Average Case is Similar

Example, 2n4 = f(x) = 2n4,
Then Omega(n) = 2n4

Case 2). if Upper Bound is not Similar to Lower Bound

in this case, Omega(n) is Not fixed but Omega(n) is the set of functions with the same order of growth as g(n).

Example 2n4 = f(x) = 3n4, This is Our Default Case,
Then, Omega(n) = c'n4, is a set of functions with 2 = c' = 3

Hope This Explained!!

Swift 3 doesn't use NS prefix anymore on URL and URLRequest, so the updated code would be:

let url = URL(string: "your_url_here")
yourWebView.loadRequest(URLRequest(url: url!))

split(x,matrix(1:n,n,length(x))[1:length(x)])

perhaps this is more clear, but the same idea:
split(x,rep(1:n, ceiling(length(x)/n),length.out = length(x)))

if you want it ordered,throw a sort around it

One important function of the main key is that it provides the path for your entry point. This is very helpful when working with nodemon. If you work with nodemon and you define the main key in your package.json as let say "main": "./src/server/app.js", then you can simply crank up the server with typing nodemon in the CLI with root as pwd instead of nodemon ./src/server/app.js.

Well, it generally depends on the shell. For bash, it marks the variable as "exportable" meaning that it will show up in the environment for any child processes you run.

Non-exported variables are only visible from the current process (the shell).

From the bash man page:

export [-fn] [name[=word]] ...
export -p

The supplied names are marked for automatic export to the environment of subsequently executed commands.

If the -f option is given, the names refer to functions. If no names are given, or if the -p option is supplied, a list of all names that are exported in this shell is printed.

The -n option causes the export property to be removed from each name.

If a variable name is followed by =word, the value of the variable is set to word.

export returns an exit status of 0 unless an invalid option is encountered, one of the names is not a valid shell variable name, or -f is supplied with a name that is not a function.

You can also set variables as exportable with the typeset command and automatically mark all future variable creations or modifications as such, with set -a.

Install mysysgit. (Same as Greg Hewgill's answer.)

Install Tortoisegit. (Tortoisegit requires mysysgit or something similiar like Cygwin.)

After TortoiseGit is installed, right-click on a folder, select Git Clone..., then enter the Url of the repository, then click Ok.

This answer is not any better than just installing mysysgit, but you can avoid the dreaded command line. :)

You can use command ionic info to get details of ionic CLI , angular CLI , Node JS version and NPM version

Are you sure that your configuration file (web.config) is at the right place and the connection string is really in the (generated) file? If you publish your file, the content of web.release.config might be copied.

The configuration and the access to the Connection string looks all right to me. I would always add a providername

<connectionStrings>
  <add name="Dbconnection" 
       connectionString="Server=localhost; Database=OnlineShopping; 
       Integrated Security=True" providerName="System.Data.SqlClient" />
</connectionStrings>

Use this

<xsl:text disable-output-escaping="yes">&amp;</xsl:text>nbsp;

edit: Downvoters should probably validate that this works first (it does, and is the most general solution to the problem.)

While you are declaring onclick in XML then you must declair method and pass View v as parameter and make the method public...

Ex:
//in xml
android:onClick="onButtonClicked"


// in java file
public void onButtonClicked(View v)
{
//your code here
}

Java does both compilation and interpretation,

In Java, programs are not compiled into executable files; they are compiled into bytecode (as discussed earlier), which the JVM (Java Virtual Machine) then interprets / executes at runtime. Java source code is compiled into bytecode when we use the javac compiler. The bytecode gets saved on the disk with the file extension .class.

When the program is to be run, the bytecode is converted the bytecode may be converted, using the just-in-time (JIT) compiler. The result is machine code which is then fed to the memory and is executed.

Javac is the Java Compiler which Compiles Java code into Bytecode. JVM is Java Virtual Machine which Runs/ Interprets/ translates Bytecode into Native Machine Code. In Java though it is considered as an interpreted language, It may use JIT (Just-in-Time) compilation when the bytecode is in the JVM. The JIT compiler reads the bytecodes in many sections (or in full, rarely) and compiles them dynamically into machine code so the program can run faster, and then cached and reused later without needing to be recompiled. So JIT compilation combines the speed of compiled code with the flexibility of interpretation.

An interpreted language is a type of programming language for which most of its implementations execute instructions directly and freely, without previously compiling a program into machine-language instructions. The interpreter executes the program directly, translating each statement into a sequence of one or more subroutines already compiled into machine code.

A compiled language is a programming language whose implementations are typically compilers (translators that generate machine code from source code), and not interpreters (step-by-step executors of source code, where no pre-runtime translation takes place)

In modern programming language implementations like in Java, it is increasingly popular for a platform to provide both options.

void foo(vector<int> test)

vector would be passed by value in this.

You have more ways to pass vectors depending on the context:-

1) Pass by reference:- This will let function foo change your contents of the vector. More efficient than pass by value as copying of vector is avoided.

2) Pass by const-reference:- This is efficient as well as reliable when you don't want function to change the contents of the vector.

zoom.cfg and global-zoom.cfg provide font size change bindings (from EmacsWiki)

• C-- or C-mousewheel-up: increases font size.
• C-+ or C-mousewheel-down: decreases font size.
• C-0 reverts font size to default.

This error can also be caused if the jar file that contains the XSD you require is not included in your deployed class path.

Make sure the dependencies are available in your container.

Add the hidden titleLabel to the parameter is the best solution.

I generated a array arrUrl which store the NSURL of the mov files in my phone album by enumerate assets block.

After that, I grab on Frame, lets say, get the frame at 3:00 second in the movie file, and generated the image file from the frame.

Next, loop over the arrUrl, and use program generate the button with image in the button, append the button to subview of the self.view.

Because I have to pass the movie Url to playMovie function, I have to assign the button.titleLabel.text with one movie url. and the the button events function, retrieve the url from the buttontitleLable.txt.

-(void)listVideos

{
   for(index=0;index<[self.arrUrl count];index++{
      UIButton *imageButton = [UIButton buttonWithType:UIButtonTypeCustom];
      imageButton.frame = CGRectMake(20,50+60*index,50,50);

      NSURL *dUrl = [self.arrUrl objectAtIndex:index];

      [imageButton setImage:[[UIImage allow] initWithCGImage:*[self getFrameFromeVideo:dUrl]] forState:UIControlStateNormal];
      [imageButton addTarget:self action:@selector(playMovie:) forControlEvents:UIControlEventTouchUpInside];
      imageButton.titleLabel.text = [NSString strinfWithFormat:@"%@",dUrl];
      imageButton.titleLabel.hidden = YES;

      [self.view addSubView:imageButton];
   }
}

-(void)playMovie:(id) sender{
   UIButton *btn = (UIButton *)sender;
   NSURL *movUrl = [NSURL URLWithString:btn.titleLabel.text];
   moviePlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:movUrl];
   [self presentMoviePlayerViewControllerAnimated:moviePlayer];
}

-(CGIImageRef *)getFrameFromVideo:(NSURL *)mUrl{
   AVURLAsset *asset = [[AVURLAsset alloc] initWithURL:mUrl option:nil];
   AVAssetImageGenerator *generator = [[AVAssetImageGenerator alloc] initWithAsset:asset];
   generator.appliesPreferredTrackTransform = YES;
   NSError *error =nil;
   CMTime = CMTimeMake(3,1);
   CGImageRef imageRef = [generator copyCGImageAtTime:time actualTime:nil error:&error];
   if(error !=nil) {
      NSLog(@"%@",sekf,error);
   }

   return @imageRef;
}

try this:

update `list`
set `test` = `number`

You can use getActivity() method to get context or You can use getContext() method .

 View root = inflater.inflate(R.layout.fragment_slideshow, container, false);
    Context c = root.getContext();

I hope it helps!

Use for, something along the lines of:

set content=
for /f "delims=" %%i in ('filename') do set content=%content% %%i

Maybe you’ll have to do setlocal enabledelayedexpansion and/or use !content! rather than %content%. I can’t test, as I don’t have any MS Windows nearby (and I wish you the same :-).

If you're stuck with Java 8 but have access to Guava 21.0 or newer, you can use Streams.stream to convert an optional into a stream.

Thus, given

import com.google.common.collect.Streams;

you can write

Optional<Other> result =
    things.stream()
        .map(this::resolve)
        .flatMap(Streams::stream)
        .findFirst();

You have two options to abruptly exit out of ForEach-Object pipeline in PowerShell:

1. Apply exit logic in Where-Object first, then pass objects to Foreach-Object, or
2. (where possible) convert Foreach-Object into a standard Foreach looping construct.

Let's see examples: Following scripts exit out of Foreach-Object loop after 2nd iteration (i.e. pipeline iterates only 2 times)":

Solution-1: use Where-Object filter BEFORE Foreach-Object:

[boolean]$exit = $false;
1..10 | Where-Object {$exit -eq $false} | Foreach-Object {
     if($_ -eq 2) {$exit = $true}    #OR $exit = ($_ -eq 2);
     $_;
}

OR

1..10 | Where-Object {$_ -le 2} | Foreach-Object {
     $_;
}

Solution-2: Converted Foreach-Object into standard Foreach looping construct:

Foreach ($i in 1..10) { 
     if ($i -eq 3) {break;}
     $i;
}

PowerShell should really provide a bit more straightforward way to exit or break out from within the body of a Foreach-Object pipeline. Note: return doesn't exit, it only skips specific iteration (similar to continue in most programming languages), here is an example of return:

Write-Host "Following will only skip one iteration (actually iterates all 10 times)";
1..10 | Foreach-Object {
     if ($_ -eq 3) {return;}  #skips only 3rd iteration.
     $_;
}

HTH

You derive B from A<B>, so the first thing the compiler does, once it sees the definition of class B is to try to instantiate A<B>. To do this it needs to known B::mytype for the parameter of action. But since the compiler is just in the process of figuring out the actual definition of B, it doesn't know this type yet and you get an error.

One way around this is would be to declare the parameter type as another template parameter, instead of inside the derived class:

template<typename Subclass, typename Param>
class A {
    public:
        void action(Param var) {
                (static_cast<Subclass*>(this))->do_action(var);
        }
};

class B : public A<B, int> { ... };

The s.insert(0, x) form is the most common.

Whenever you see it though, it may be time to consider using a collections.deque instead of a list.

I did this for a home folder where all the folders are on the desktops of the corresponding users, reachable through a shortcut which did not have the appropriate permissions, so that users couldn't see it even if it was there. So I used Robocopy with the parameter to overwrite the file with the right settings:

FOR /F "tokens=*" %G IN ('dir /b') DO robocopy  "\\server02\Folder with shortcut" "\\server02\home\%G\Desktop" /S /A /V /log+:C:\RobocopyShortcut.txt /XF *.url *.mp3 *.hta *.htm *.mht *.js *.IE5 *.css *.temp *.html *.svg *.ocx *.3gp *.opus *.zzzzz *.avi *.bin *.cab *.mp4 *.mov *.mkv *.flv *.tiff *.tif *.asf *.webm *.exe *.dll *.dl_ *.oc_ *.ex_ *.sy_ *.sys *.msi *.inf *.ini *.bmp *.png *.gif *.jpeg *.jpg *.mpg *.db *.wav *.wma *.wmv *.mpeg *.tmp *.old *.vbs *.log *.bat *.cmd *.zip /SEC /IT /ZB /R:0

As you see there are many file types which I set to ignore (just in case), just set them for your needs or your case scenario.

It was tested on Windows Server 2012, and every switch is documented on Microsoft's sites and others.

Mp4 files can be playable with transparent background using seeThrou Js library. All you need to combine actual video and alpha channel in the single video. Also make sure to keep video height dimension below 1400 px as some of the old iphone devices wont play videos with dimension more than 2000. This is pretty useful in safari desktop and mobile devices which doesnt support webm at this time.

k old post but no one use list expression to answer :P

list =[ ['a','b'], ['a','c'], ['b','d'] ]
Search = 'c'

# return if it find in either item 0 or item 1
print [x for x,y in list if x == Search or y == Search]

# return if it find in item 1
print [x for x,y in list if y == Search]

A practical example using a jQuery example might be

 var today = new Date();
 $('#'+[today.getMonth()+1, today.getDate(), today.getFullYear()].join("_")).whatever();

I do that in a calendar tool that I am using, this way on the page load, I can do certain things with today's date.

For those that found the above solutions not working, it's because you may have a this inside your class, which implies an extension method which, as the error message says, only makes sense on a non-generic static class. Your class isn't static. This doesn't seem to be something that makes sense as an extension method, since it's acting on the instance in question, so remove the this.

You can create your custom SharedPreference class

public class YourPreference {   
    private static YourPreference yourPreference;
    private SharedPreferences sharedPreferences;

    public static YourPreference getInstance(Context context) {
        if (yourPreference == null) {
            yourPreference = new YourPreference(context);
        }
        return yourPreference;
    }

    private YourPreference(Context context) {
        sharedPreferences = context.getSharedPreferences("YourCustomNamedPreference",Context.MODE_PRIVATE);
    }

    public void saveData(String key,String value) {
        SharedPreferences.Editor prefsEditor = sharedPreferences.edit();
        prefsEditor .putString(key, value);
        prefsEditor.commit();           
    }

    public String getData(String key) {
        if (sharedPreferences!= null) {
           return sharedPreferences.getString(key, "");
        }
        return "";         
    }
}

You can get YourPrefrence instance like:

YourPreference yourPrefrence = YourPreference.getInstance(context);
yourPreference.saveData(YOUR_KEY,YOUR_VALUE);

String value = yourPreference.getData(YOUR_KEY);

Below is a sample code which uses aync/await to have an actual delay.

There are many constraints and this may not be useful, but just posting here for fun..

function delay(delayInms) {
  return new Promise(resolve => {
    setTimeout(() => {
      resolve(2);
    }, delayInms);
  });
}

async function sample() {
  console.log('a');
  console.log('waiting...')
  let delayres = await delay(3000);
  console.log('b');
}
sample();

If you have already set labels for your axis like how @andyhasit and @Marcus mentioned, and would like to change it at a later time, then you can try this:

chart.options.scales.yAxes[ 0 ].scaleLabel.labelString = "New Label";

Full config for reference:

var chartConfig = {
    type: 'line',
    data: {
      datasets: [ {
        label: 'DefaultLabel',
        backgroundColor: '#ff0000',
        borderColor: '#ff0000',
        fill: false,
        data: [],
      } ]
    },
    options: {
      responsive: true,
      scales: {
        xAxes: [ {
          type: 'time',
          display: true,
          scaleLabel: {
            display: true,
            labelString: 'Date'
          },
          ticks: {
            major: {
              fontStyle: 'bold',
              fontColor: '#FF0000'
            }
          }
        } ],
        yAxes: [ {
          display: true,
          scaleLabel: {
            display: true,
            labelString: 'value'
          }
        } ]
      }
    }
  };

Another option is to use apt-file (i.e. apt-file search makeinfo). It may or may not be installed in your distro by default, but it is a great tool for determining what package a file belongs to.

Use whatever navigation key you want to get inside the parentheses, then you can use either yi( or yi) to copy everything within the matching parens. This also works with square brackets (e.g. yi]) and curly braces. In addition to y, you can also delete or change text (e.g. ci), di]).

I tried this with double and single-quotes and it appears to work there as well. For your data, I do:

write (*, '(a)') 'Computed solution coefficients:'

Move cursor to the C, then type yi'. Move the cursor to a blank line, hit p, and get

Computed solution coefficients:

As CMS noted, this works for visual mode selection as well - just use vi), vi}, vi', etc.

while (fscanf(input,"%s",arr) != EOF && count!=7) {
  len=strlen(arr); 
  count++; 
}

use this

<body onload =  "if (location.search.length < 1){window.location.reload()}">

Also, in the above case there should be only one implicit function whose type is double => Int. Otherwise, the compiler gets confused and won't compile properly.

//this won't compile

implicit def doubleToInt(d: Double) = d.toInt
implicit def doubleToIntSecond(d: Double) = d.toInt
val x: Int = 42.0

I think it has to do with your second element in storbinary. You are trying to open file, but it is already a pointer to the file you opened in line file = open(local_path,'rb'). So, try to use ftp.storbinary("STOR " + i, file).

JaredPar's code works but only for one level of inheritance. For unlimited levels of inheritance, use the following code

public bool IsTypeDerivedFromGenericType(Type typeToCheck, Type genericType)
{
    if (typeToCheck == typeof(object))
    {
        return false;
    }
    else if (typeToCheck == null)
    {
        return false;
    }
    else if (typeToCheck.IsGenericType && typeToCheck.GetGenericTypeDefinition() == genericType)
    {
        return true;
    }
    else
    {
        return IsTypeDerivedFromGenericType(typeToCheck.BaseType, genericType);
    }
}

It’s not easy to display live video stream from an IP camera on a web page because you need wide internet bandwidth and a great video player that is compatible with the major browsers.

But fortunately there are some cloud based services that can do this job for us. One of the best is IPCamLive. This service can receive RTSP/H264 video stream from an IP Camera and can broadcast it to the viewers. IPCamLive has Flash/HTML5 video player component that will display the video on PC, MAC, tablet or mobile. The greatest thing is that this site generates the needed HTML snippet for embedding the live video like this:

<iframe src="http://ipcamlive.com/player/player.php?alias=szekesfehervar" width="800px" height="600px"/>

So we just need to copy paste it into our HTML file without any modification.

I use this code:

show-hide button

 <a @click.stop="visualSwitch()"> show hide </a>

show-hide element

<div class="dialog-popup" v-if="visualState" @click.stop=""></div>

script

data () { return {
    visualState: false,
}},
methods: {
    visualSwitch() {
        this.visualState = !this.visualState;
        if (this.visualState)
            document.addEventListener('click', this.visualState);
        else
            document.removeEventListener('click', this.visualState);
    },
},

Update: remove watch; add stop propagation

I believe this isn't going to work for you as you use C# and my solution includes a Java library, however maybe others will find it helpful.

For capturing custom screenshots you can use the Shutterbug library. The specific call for this purpose would be:

I redefined those dependencies with scope test. Scope provided did not work for me.

Save the following code to a file, for example, named stash. Usage is stash <filename_regex>. The argument is the regular expression for the full path of the file. For example, to stash a/b/c.txt, stash a/b/c.txt or stash .*/c.txt, etc.

$ chmod +x stash
$ stash .*.xml
$ stash xyz.xml

Code to copy into the file:

#! /usr/bin/expect --
log_user 0
set filename_regexp [lindex $argv 0]

spawn git stash -p

for {} 1 {} {
  expect {
    -re "diff --git a/($filename_regexp) " {
      set filename $expect_out(1,string)
    }
    "diff --git a/" {
      set filename ""
    }
    "Stash this hunk " {
      if {$filename == ""} {
        send "n\n"
      } else {
        send "a\n"
        send_user "$filename\n"

This parameter is just about whether you are going to use complex html into the tooltip. Set it to true and then hit the html into the title attribute of the tag.

See this fiddle here - I've set the html attribute to true through the data-html="true" in the <a> tag and then just added in the html ad hoc as an example.

Use a SQL function (I'm the author):

• https://github.com/teopost/oracle-scripts/blob/master/fn_gen_inserts.sql

Usage:

select fn_gen_inserts('select * from tablename', 'p_new_owner_name', 'p_new_table_name')
from dual;

where:

p_sql            – dynamic query which will be used to export metadata rows
p_new_owner_name – owner name which will be used for generated INSERT
p_new_table_name – table name which will be used for generated INSERT

p_sql in this sample is 'select * from tablename'

You can find original source code here:

• http://dbaora.com/oracle-generate-rows-as-insert-statements-from-table-view-using-plsql/

Ashish Kumar's script generates individually usable insert statements instead of a SQL block, but supports fewer datatypes.

1. Download certificate from this link: https://github.com/bagder/ca-bundle

SelectionChange is the event built into the Excel Object model for this. It should do exactly as you want, firing any time the user clicks anywhere...

I'm not sure that I understand your objections to global variables here, you would only need 1 if you use the Application.SelectionChange event. However, you wouldn't need any if you utilize the Workbook class code behind (to trap the Workbook.SelectionChange event) or the Worksheet class code behind (to trap the Worksheet.SelectionChange) event. (Unless your issue is the "global variable reset" problem in VBA, for which there is only one solution: error handling everywhere. Do not allow any unhandled errors, instead log them and/or "soft-report" an error as a message box to the user.)

You might also need to trap the Worksheet.Activate() and Worksheet.Deactivate() events (or the equivalent in the Workbook class) and/or the Workbook.Activate and Workbook.Deactivate() events so that you know when the user has switched worksheets and/or workbooks. The Window activate and deactivate events should make this approach complete. They could all call the same exact procedure, however, they all denote the same thing: the user changed the "focus", if you will.

If you don't like VBA, btw, you can do the same using VB.NET or C#.

[Edit: Dbb makes a very good point about the SelectionChange event not picking up a click when the user clicks within the currently selected cell. If you need to pick that up, then you would need to use subclassing.]

The issue can also be due to lack of hard drive space. The installation will succeed but on startup, oracle won't be able to create the required files and will fail with the same above error message.

I create a python code to delete all in namespace

delall.py

import json,sys,os;

obj=json.load(sys.stdin);
for item in obj["items"]:
        os.system("kubectl delete " + item["kind"] + "/" +item["metadata"]["name"] + " -n yournamespace")

and then

kubectl get all -n kong -o json | python delall.py

In Java when you are making an object from a class like Person p = new Person();, p is actually an address of a memory location which is pointing to a type of Person.

When use a statemenet to print p you will see an address. The new key word makes a new memory location containing all the instance variables and methods which are included in class Person and p is the reference variable pointing to that memory location.

Did you try passwd -d root? Most likely, this will do what you want.

You can also manually edit /etc/shadow: (Create a backup copy. Be sure that you can log even if you mess up, for example from a rescue system.) Search for "root". Typically, the root entry looks similar to

root:$X$SK5xfLB1ZW:0:0...

There, delete the second field (everything between the first and second colon):

root::0:0...

Some systems will make you put an asterisk (*) in the password field instead of blank, where a blank field would allow no password (CentOS 8 for example)

root:*:0:0...

Save the file, and try logging in as root. It should skip the password prompt. (Like passwd -d, this is a "no password" solution. If you are really looking for a "blank password", that is "ask for a password, but accept if the user just presses Enter", look at the manpage of mkpasswd, and use mkpasswd to create the second field for the /etc/shadow.)

create or replace 
TRIGGER triggername BEFORE INSERT  ON 
table FOR EACH ROW 
BEGIN
/*
Write any select condition if you want to get the data from other tables
*/
:NEW.COLUMNA:= UPPER(COLUMNA); 
--:NEW.COUMNa:= NULL;
END; 

The above trigger will update the column value before inserting. For example if we give the value of COLUMNA as null it will update the column as null for each insert statement.

To hide those warnings, you could do this before your actual code.

import os
os.environ['TF_CPP_MIN_LOG_LEVEL']='2'
import tensorflow as tf

Well i'll pretty much sum up what everyone else here said before...Anyways, here's the code i built according to the good answers :) All is left to do is copy and use...

The settings you need are "Local echo" and "Line editing" under the "Terminal" category on the left.

To get the characters to display on the screen as you enter them, set "Local echo" to "Force on".

To get the terminal to not send the command until you press Enter, set "Local line editing" to "Force on".

Explanation:

From the PuTTY User Manual (Found by clicking on the "Help" button in PuTTY):

4.3.8 ‘Local echo’

With local echo disabled, characters you type into the PuTTY window are not echoed in the window by PuTTY. They are simply sent to the server. (The server might choose to echo them back to you; this can't be controlled from the PuTTY control panel.)

Some types of session need local echo, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local echo is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local echo to be turned on, or force it to be turned off, instead of relying on the automatic detection.

4.3.9 ‘Local line editing’ Normally, every character you type into the PuTTY window is sent immediately to the server the moment you type it.

If you enable local line editing, this changes. PuTTY will let you edit a whole line at a time locally, and the line will only be sent to the server when you press Return. If you make a mistake, you can use the Backspace key to correct it before you press Return, and the server will never see the mistake.

Since it is hard to edit a line locally without being able to see it, local line editing is mostly used in conjunction with local echo (section 4.3.8). This makes it ideal for use in raw mode or when connecting to MUDs or talkers. (Although some more advanced MUDs do occasionally turn local line editing on and turn local echo off, in order to accept a password from the user.)

Some types of session need local line editing, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local line editing is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local line editing to be turned on, or force it to be turned off, instead of relying on the automatic detection.

Putty sometimes makes wrong choices when "Auto" is enabled for these options because it tries to detect the connection configuration. Applied to serial line, this is a bit trickier to do.

I'm not sure if I understand your question properly, but it shouldn't matter if this div is a child of some other div. You can simply get text from all divs with class bgHeaderH2 by using following code:

$(".bgHeaderH2").text();

In Python, you can use urllib2 (http://docs.python.org/2/library/urllib2.html) to do all of that work for you.

Simply enough:

import urllib2
f =  urllib2.urlopen(url)
print f.read() 

Will print the received HTTP response.

To pass GET/POST parameters the urllib.urlencode() function can be used. For more information, you can refer to the Official Urllib2 Tutorial

I think all you need to do for your function is just add PtrSafe: i.e. the first line of your first function should look like this:

Private Declare PtrSafe Function swe_azalt Lib "swedll32.dll" ......

In VB2008, it works this way:

Project>Add References

Then click on the Recent tab where you can see list of references used recently. Locate the one you do not want and delet it. Then you close without adding anything.

zoom: 145%;
-moz-transform: scale(1.45);

use this to be on the safer side

The inflate() method takes three parameters:

1. The id of a layout XML file (inside R.layout),

2. A parent ViewGroup into which the fragment's View is to be inserted,

3. A third boolean telling whether the fragment's View as inflated from the layout XML file should be inserted into the parent ViewGroup.

In this case we pass false because the View will be attached to the parent ViewGroup elsewhere, by some of the Android code we call (in other words, behind our backs). When you pass false as last parameter to inflate(), the parent ViewGroup is still used for layout calculations of the inflated View, so you cannot pass null as parent ViewGroup .

 View rootView = inflater.inflate(R.layout.fragment_photos, container, false);

So, You need to call rootView in here

ListView lv = (ListView)rootView.findViewById(R.id.lv_contact);

Checking if v contains the element x:

#include <algorithm>

if(std::find(v.begin(), v.end(), x) != v.end()) {
    /* v contains x */
} else {
    /* v does not contain x */
}

Checking if v contains elements (is non-empty):

if(!v.empty()){
    /* v is non-empty */
} else {
    /* v is empty */
}

DECLARE @isAvailable      BIT = 0;

IF EXISTS(SELECT 1  FROM [User] WHERE (UserID = 20070022))
BEGIN
 SET @isAvailable = 1
END

initially isAvailable boolean value is set to 0

you need to use add class open in <div class="btn-group open">

and in li add class="active"

You can simply use the WebDriver object, and access to the page source code via its @property field page_source...

Try this code snippet :-)

from selenium import webdriver
driver = webdriver.Firefox('path/to/executable')
driver.get('https://some-domain.com')
source = driver.page_source
if 'stuff' in source:
    print('found...')
else:
    print('not in source...')

Building on @Kristian's answer, I had a desire to display a fixed number of decimal places. That can be accomplished with other arguments in the QString::number(...) function. For instance, I wanted 3 decimal places:

double value = 34.0495834;
QString strValue = QString::number(value, 'f', 3);
// strValue == "34.050"

The 'f' specifies decimal format notation (more info here, you can also specify scientific notation) and the 3 specifies the precision (number of decimal places). Probably already linked in other answers, but more info about the QString::number function can be found here in the QString documentation

Here is my take on the problem:

from math import sqrt
from itertools import count, islice

def is_prime(n):
    return n > 1 and all(n % i for i in islice(count(2), int(sqrt(n)-1)))

This is a really simple and concise algorithm, and therefore it is not meant to be anything near the fastest or the most optimal primality check algorithm. It has a time complexity of O(sqrt(n)). Head over here to learn more about primality tests done right and their history.

Explanation

I'm gonna give you some insides about that almost esoteric single line of code that will check for prime numbers:

• First of all, using range() in Python 2 is really a bad idea, because it will create a list of numbers, which uses a lot of memory. Using xrange() is better, because it creates a generator, which only needs to memorize the initial arguments you provide, and generates every number on-the-fly. If you're using Python 3, range() has been converted to a generator by default. By the way, this is still not the best solution: trying to call xrange(n) for some n such that n > 231-1 (which is the maximum value for a C long) raises OverflowError. Therefore the best way to create a range generator is to use itertools:

   xrange(2147483647+1) # OverflowError
  
   from itertools import count, islice
  
   count(1)                        # Count from 1 to infinity with step=+1
   islice(count(1), 2147483648)    # Count from 1 to 2^31 with step=+1
   islice(count(1, 3), 2147483648) # Count from 1 to 3*2^31 with step=+3
  

• You do not actually need to go all the way up to n if you want to check if n is a prime number. You can dramatically reduce the tests and only check from 2 to v(n) (square root of n). Here's an example:

  Let's find all the divisors of n = 100, and list them in a table:

   2  x  50 = 100
   4  x  25 = 100
   5  x  20 = 100
  10  x  10 = 100 <-- sqrt(100)
  20  x  5  = 100     
  25  x  4  = 100
  50  x  2  = 100
  

  You will easily notice that, after the square root of n, all the divisors we find were actually already found. For example 20 was already found doing 100/5. The square root of a number is the exact mid-point where the divisors we found begin being duplicated. Therefore, to check if a number is prime, you'll only need to check from 2 to sqrt(n).

• Why sqrt(n)-1 then, and not just sqrt(n)? That's just because the second argument provided to itertools.islice() is the number of iterations to execute. islice(count(a), b) stops after b iterations. That's the reason why:

   for number in islice(count(10), 2):
       print number,
  
   # Will print: 10 11
  
   for number in islice(count(1, 3), 10):
       print number,
  
   # Will print: 1 4 7 10 13 16 19 22 25 28
  

• The function all(...) is the same of the following:

   def all(iterable):
       for element in iterable:
           if not element:
               return False
       return True
  

  It literally checks for all the elements in the iterable, returning False when any of them evaluates to False (which for an integer means only if it's zero). Why do we use it then? First of all, we don't need to use an additional index variable (like we would do using a loop), other than that: just for concision, there's no real need of it, but it looks way less bulky to work with only a single line of code instead of several nested lines.

Extended version

I'm including an "unpacked" version of the is_prime() function, to make it easier to understand and read:

from math import sqrt
from itertools import count, islice

def is_prime(n):
    if n < 2:
        return False

    for number in islice(count(2), int(sqrt(n) - 1)):
        if n % number == 0:
            return False

    return True

Grid computing is where more than one computer coordinates to solve a problem together. Often used for problems involving a lot of number crunching, which can be easily parallelisable.

Cloud computing is where an application doesn't access resources it requires directly, rather it accesses them through something like a service. So instead of talking to a specific hard drive for storage, and a specific CPU for computation, etc. it talks to some service that provides these resources. The service then maps any requests for resources to its physical resources, in order to provide for the application. Usually the service has access to a large amount of physical resources, and can dynamically allocate them as they are needed.

In this way, if an application requires only a small amount of some resource, say computation, then the service only allocates a small amount, say on a single physical CPU (that may be shared with some other application using the service). If the application requires a large amount of some resource, then the service allocates that large amount, say a grid of CPUs. The application is relatively oblivious to this, and all the complex handling and coordination is performed by the service, not the application. In this way the application can scale well.

For example a web site written "on the cloud" may share a server with many other web sites while it has a low amount of traffic, but may be moved to its own dedicated server, or grid of servers, if it ever has massive amounts of traffic. This is all handled by the cloud service, so the application shouldn't have to be modified drastically to cope.

A cloud would usually use a grid. A grid is not necessarily a cloud or part of a cloud.

Google now has a feature stating that it won't allow insecure devices to send emails. When I ran my program it came up with the error in the first post. I had to go into my account and allow insecure apps to send emails, which I did by clicking on my account, going into the security tab, and allowing insecure apps to use my gmail.

Just want to let you guys know, the accepted answer doesn't always work.

Here's an example it will fail.

if <href='/list'>

href = $('css_selector').attr('href')
"/list"
href = document.querySelector('css_selector').href
"http://localhost/list"

or you could append the href you got from jQuery to this

href = document.URL +$('css_selector').attr('href');

or jQuery way

href = $('css_selector').prop('href')

Finally, invoke it to change the browser current page's url

window.location.href = href

or pop it out using window.open(url)

Here's an example in JSFiddle.

This worked for me:

yourViewController.modalPresentationStyle = UIModalPresentationStyle.fullScreen

The pandas.DataFrame.dropna function removes missing values (e.g. NaN, NaT).

For example the following code would remove any columns from your dataframe, where all of the elements of that column are missing.

df.dropna(how='all', axis='columns')

A bit weird, but this worked for me

    $array1 = array("Post Slider", "Post Slider Wide", "Post Slider");
    $array2 = array("Tools Sliders", "Tools Sliders", "modules-test");
    $array3 = array();

    $count = count($array1);

    for($x = 0; $x < $count; $x++){
       $array3[$array1[$x].$x] = $array2[$x];
    }

    foreach($array3 as $key => $value){
        $output_key = substr($key, 0, -1);
        $output_value = $value;
        echo $output_key.": ".$output_value."<br>";
    }

You need to use the name attribute of the upload file that is in the HTML of the site. Example:

autocomplete="off" name="image">

You see name="image">? You can find it in the HTML of a site for uploading the file. You need to use it to upload the file with Multipart/form-data

script:

import requests

site = 'https://prnt.sc/upload.php' # the site where you upload the file
filename = 'image.jpg'  # name example

Here, in the place of image, add the name of the upload file in HTML

up = {'image':(filename, open(filename, 'rb'), "multipart/form-data")}

If the upload requires to click the button for upload, you can use like that:

data = {
     "Button" : "Submit",
}

Then start the request

request = requests.post(site, files=up, data=data)

And done, file uploaded succesfully

Make it the following:

.nav.navbar-nav.navbar-right li a {
    color: blue;
}

The above will target the specific links, which is what you want, versus styling the entire list blue, which is what you were initially doing. Here is a JsFiddle.

The other way would be creating another class and implementing it like so:

HTML

<li><a href="#" class="color-me"><span class="glyphicon glyphicon-list-alt"></span> R&eacute;sum&eacute;</a></li>

CSS

.color-me{
    color:blue;
}

Also demonstrated in this JsFiddle

I hope this could be helpful for whom has similar problem . In ObjectExplorer window, select your database=> Tables,=> your table=> Constraints. If the customer is defined on create column time, you can see the default name of constraint including the column name. then use:

ALTER TABLE  yourTableName DROP CONSTRAINT DF__YourTa__NewCo__47127295;

(the constraint name is just an example)

For whoever stumbled across this using ES6 / ES7 style with native promises, here is a pattern you can adopt...

const user = { id: 1, name: "Fart Face 3rd"};
const userUpdate = { name: "Pizza Face" };

try {
    user = await new Promise( ( resolve, reject ) => {
        User.update( { _id: user.id }, userUpdate, { upsert: true, new: true }, ( error, obj ) => {
            if( error ) {
                console.error( JSON.stringify( error ) );
                return reject( error );
            }

            resolve( obj );
        });
    })
} catch( error ) { /* set the world on fire */ }

For security: Gives each user permission to access the database only through a small set of views that contain the specific data the user or group of users is authorized to see, restricting user access to other data.

Simplicity for queries and structure: A view can draw data from several tables and present a single table, simplifying the information and turning multi-table queries into single-table queries for a view and it give users a specific view of the database structure, presenting the database as a set of virtual tables specific to particular users or groups of users.

For create consistent database structure: Views present a consistent, unchanged image of the database structure, even if underlying source tables are changed.

This will convert to a numeric value without the need to cast or specify length or digits:

STRING_COL+0.0

If your column is an INT, can leave off the .0 to avoid decimals:

STRING_COL+0

I believe you can also do:

$sortDirection = 'desc';

$user->with(['comments' => function ($query) use ($sortDirection) {
    $query->orderBy('column', $sortDirection);
}]);

That allows you to run arbitrary logic on each related comment record. You could have stuff in there like:

$query->where('timestamp', '<', $someTime)->orderBy('timestamp', $sortDirection);

I'm trying to get in to enable the BATTERY_STATS for GSam Monitor Pro, but I think it's disable through the Airwatch MDM software my company makes me use. They pay for it so I guess I'm stuck.

You can find some resources related to developing web services client using Apache axis2 here.

I recommend another option. jQuery UI has a new position feature that allows you to position elements relative to each other. For complete documentation and demo see: http://jqueryui.com/demos/position/#option-offset.

Here's one way to position your elements using the position feature:

var options = {
    "my": "top left",
    "at": "top left",
    "of": ".layer1"
};
$(".layer2").position(options);

I had a unique key, just had to pass it as a prop like this:

<CompName key={msg._id} message={msg} />

I assume that I do have a <div> input container area with text, sliders and buttons in it, and want to inhibit accidental double-taps in that <div>. The following does not inhibit zooming on the input area, and it does not relate to double-tap and zooming outside my <div> area. There are variations depending on the browser app.

I just tried it.

(1) For Safari on iOS, and Chrome on Android, and is the preferred method. Works except for Internet app on Samsung, where it disables double-taps not on the full <div>, but at least on elements that handle taps. It returns return false, with exception on text and range inputs.

$('selector of <div> input area').on('touchend',disabledoubletap);

function disabledoubletap(ev) {

    var preventok=$(ev.target).is('input[type=text],input[type=range]');

    if(preventok==false) return false; 
}

(2) Optionally for built-in Internet app on Android (5.1, Samsung), inhibits double-taps on the <div>, but inhibits zooming on the <div>:

$('selector of <div> input area').on('touchstart touchend',disabledoubletap);

(3) For Chrome on Android 5.1, disables double-tap at all, does not inhibit zooming, and does nothing about double-tap in the other browsers. The double-tap-inhibiting of the <meta name="viewport" ...> is irritating, because <meta name="viewport" ...> seems good practice.

<meta name="viewport" content="width=device-width, initial-scale=1, 
          maximum-scale=5, user-scalable=yes">

For MacOS users, if you forget your root password, @thusharaK's answer(https://stackoverflow.com/a/28601069/5628856) is good, but there are a little more tricks:

If you are using system preference to start mysql serverside, simply

sudo mysqld_safe --skip-grant-tables

might not work for you.

You have to make sure the command line arguments is same with system start config.

The following command works for me:

/usr/local/mysql/bin/mysqld --user=_mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --plugin-dir=/usr/local/mysql/lib/plugin --log-error=/usr/local/mysql/data/mysqld.local.err --pid-file=/usr/local/mysql/data/mysqld.local.pid --keyring-file-data=/usr/local/mysql/keyring/keyring --early-plugin-load=keyring_file=keyring_file.so --skip-grant-tables

You can use

ps aux | grep mysql

to check your own.

You can use an extension method:

public static class StringExtension
{
    public static string GetLast(this string source, int tail_length)
    {
       if(tail_length >= source.Length)
          return source;
       return source.Substring(source.Length - tail_length);
    }
}

And then call:

string mystring = "34234234d124";
string res = mystring.GetLast(4);

When the C# 5 CTP was introduced, you certainly could mark Main with async... although it was generally not a good idea to do so. I believe this was changed by the release of VS 2013 to become an error.

Unless you've started any other foreground threads, your program will exit when Main completes, even if it's started some background work.

What are you really trying to do? Note that your GetList() method really doesn't need to be async at the moment - it's adding an extra layer for no real reason. It's logically equivalent to (but more complicated than):

public Task<List<TvChannel>> GetList()
{
    return new GetPrograms().DownloadTvChannels();
}

The problem you're running into is that most background thread / worker APIs will create the thread in a Multithreaded Apartment state. The error message indicates that the control requires the thread be a Single Threaded Apartment.

You can work around this by creating a thread yourself and specifying the STA apartment state on the thread.

var t = new Thread(MyThreadStartMethod);
t.SetApartmentState(ApartmentState.STA);
t.Start();

In the for, you have an iteration, then for each element of that loop which probably is a scalar, has no index. When each element is an empty array, single variable, or scalar and not a list or array you cannot use indices.

I solved this issue to update .htaccess file inside your workspace (like C:\xampp\htdocs\Nayan\.htaccess in my case).

Just update or add this php_value max_execution_time 300 line before # END WordPress. Then save the file and try to install again.

If the error occurs again, you can maximize the value from 300 to 600.

Here is how to clear all trash & caches (without other private data in browsers) by a command line. This is a command line batch script that takes care of all trash (as of April 2014):

erase "%TEMP%\*.*" /f /s /q
for /D %%i in ("%TEMP%\*") do RD /S /Q "%%i"

erase "%TMP%\*.*" /f /s /q
for /D %%i in ("%TMP%\*") do RD /S /Q "%%i"

erase "%ALLUSERSPROFILE%\TEMP\*.*" /f /s /q
for /D %%i in ("%ALLUSERSPROFILE%\TEMP\*") do RD /S /Q "%%i"

erase "%SystemRoot%\TEMP\*.*" /f /s /q
for /D %%i in ("%SystemRoot%\TEMP\*") do RD /S /Q "%%i"


@rem Clear IE cache -  (Deletes Temporary Internet Files Only)
RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 8
erase "%LOCALAPPDATA%\Microsoft\Windows\Tempor~1\*.*" /f /s /q
for /D %%i in ("%LOCALAPPDATA%\Microsoft\Windows\Tempor~1\*") do RD /S /Q "%%i"

@rem Clear Google Chrome cache

I am pretty sure it will run for some time when you first run it :) Enjoy!

Update:

So just to verify, it is not currently possible to set the click_action parameter via the Firebase Console.

So I've been trying to do this in the Firebase Notifications Console with no luck. Since I can't seem to find anywhere to place the click_action value in the console, what I mainly did to test this out is to add a custom key/value pair in the Notification (Advance Options > Custom Data):

Key: click_action
Value: <your_preferred_value>

then tried calling RemoteMessage.getNotification().getClickAction() in onMessageReceived() to see if it was retrieving the correct value, but it always returns null. So next I tried calling RemoteMessage.getData().get(< specified_key >) and was able to retrieve the value I added.

NOTE: I am not entirely sure if that is okay to be used as a workaround, or if it's against best practice. I would suggest using your own app server but your post is specific to the Firebase Console.

The way the client app and the notification behaves still depends on how you program it. With that said, I think you can use the above as a workaround, using the value retrieved from the getData(), then having the Notification call this or that. Hope this helps somehow. Cheers! :D

I've posted this comment on a seperate StackOverflow thread, but thought it was worth repeating here:

For our in-house ASP.Net app, adding the "X-UA-Compatible" tag on the web page, in the web.config or in the code-behind made absolutely no difference.

The only thing that worked for us was to manually turn off this setting in IE8:

(Sigh.)

This problem only seems to happen with IE8 & IE9 on intranet sites. External websites will work fine and use the correct version of IE8/9, but for internal websites, IE9 suddenly decides it's actually IE7, and doesn't have any HTML 5 support.

No, I don't quite understand this logic either.

My reluctant solution has been to test whether the browser has HTML 5 support (by creating a canvas, and testing if it's valid), and displaying this message to the user if it's not valid:

It's not particularly user-friendly, but getting the user to turn off this annoying setting seems to be the only way to let them run in-house HTML 5 web apps properly.

Or get the users to use Chrome. ;-)

Internet Explorer (IE8 and lower) doesn't support addEventListener(...). It has its own event model using the attachEvent method. You could use some code like this:

var element = document.getElementById('container');
if (document.addEventListener){
    element .addEventListener('copy', beforeCopy, false); 
} else if (el.attachEvent){
    element .attachEvent('oncopy', beforeCopy);
}

Though I recommend avoiding writing your own event handling wrapper and instead use a JavaScript framework (such as jQuery, Dojo, MooTools, YUI, Prototype, etc) and avoid having to create the fix for this on your own.

By the way, the third argument in the W3C model of events has to do with the difference between bubbling and capturing events. In almost every situation you'll want to handle events as they bubble, not when they're captured. It is useful when using event delegation on things like "focus" events for text boxes, which don't bubble.

In addition to the native versions, but you may want to try BitNami MAMP Stacks (disclaimer, I am one of the developers). They are completely free, all-in-one bundles of Apache, MySQL, PHP and a several other third-party libraries and utilities that are useful when developing locally. In particular, they are completely self-contained so you can have several one installed at the same time, with different versions of Apache and MySQL and they will not interfere with each other. You can get them from http://bitnami.org/stack/mampstack or directly from the Mac OS X app store https://itunes.apple.com/app/mamp-stack/id571310406

If it is because of the overhead in terms of creating objects, then it probably can't be sped up at all with SA.

If it is because it is loading up related objects, then you might be able to do something with lazy loading. Are there lots of objects being created due to references? (IE, getting a Company object also gets all of the related People objects).

UPDATE: TypeScript 3.4

You can simply use as const:

const AwesomeType = {
   Foo: "foo",
   Bar: "bar"
} as const;

TypeScript 2.1

This can also be done this way. Hope it help somebody.

const AwesomeType = {
    Foo: "foo" as "foo",
    Bar: "bar" as "bar"
};

type AwesomeType = (typeof AwesomeType)[keyof typeof AwesomeType];

console.log(AwesomeType.Bar); // returns bar
console.log(AwesomeType.Foo); // returns foo

function doSth(awesometype: AwesomeType) {
    console.log(awesometype);
}

doSth("foo") // return foo
doSth("bar") // returns bar
doSth(AwesomeType.Bar) // returns bar
doSth(AwesomeType.Foo) // returns foo
doSth('error') // does not compile

To complement the other answers: if you want to reset all background properties to their initial value (which includes background-color: transparent and background-image: none) without explicitly specifying any value such as transparent or none, you can do so by writing:

background: initial;

Noticed mine worked on chrome. Got it to work in Firefox by going to <about:config> and setting full-screen-api.allow-trusted-requests-only to false.

After full screen worked once, I could set that back to true, and full screen still worked which was quite perplexing.

You can have all legal string characters as part of the key if you use array notation. For example, obj['!#$%^&*()_']

SSH doesn't use the : syntax when specifying a port. The easiest way to do this is to edit your ~/.ssh/config file and add:

Host git.host.de
  Port 4019

Then specify just git.host.de without a port number.

I tried

Document.getElementsByClassName('option0')

Which resulted in the error: Uncaught TypeError: Document.getElementsByClass is not a function

After that I tried:

document.getElementsByClassName('option0')

And it works!

To make the use of lambda : There are three type of operation:
1. Accept parameter --> Consumer
2. Test parameter return boolean --> Predicate
3. Manipulate parameter and return value --> Function

Java Functional interface upto two parameter:
Single parameter interface
Consumer
Predicate
Function

Two parameter interface
BiConsumer
BiPredicate
BiFunction

For more than two, you have to create functional interface as follow(Consumer type):

@FunctionalInterface
public interface FiveParameterConsumer<T, U, V, W, X> {
    public void accept(T t, U u, V v, W w, X x);
}

For forms, use the [FromForm] attribute instead of the [FromBody] attribute.

The below controller works with ASP.NET Core 1.1:

public class MyController : Controller
{
    [HttpPost]
    public async Task<IActionResult> Submit([FromForm] MyModel model)
    {
        //...
    }
}

Note: [FromXxx] is required if your controller is annotated with [ApiController]. For normal view controllers it can be omitted.

It is important to highlight that the Property (MaximumErrorCount) that needs to be changed must be set as more than 0 (which is the default) in the Package level and not in the specific control that is showing the error (I tried this and it does not work!)

Be sure that in the Properties Window, the Pull down menu is set to "Package", then look for the property MaximumErrorCount to change it.

Use the glob function in a foreach loop to do whatever is an option. I also used the file_exists function in the example below to check if the directory exists before going any further.

$directory = 'my_directory/';
$extension = '.txt';

if ( file_exists($directory) ) {
   foreach ( glob($directory . '*' . $extension) as $file ) {
      echo $file;
   }
}
else {
   echo 'directory ' . $directory . ' doesn\'t exist!';
}

I know its quite late but for anyone looking to do it from now on, I hope this answer proves of some help. If you have CodeRush Express (free version, and a 'must have') installed, it offers a simple way to change a project wide namespace. You just place your cursor on the namespace that you want to change and it shall display a smart tag (a little blue box) underneath namespace string. You can either click that box or press Ctrl + keys to see the Rename option. Select it and then type in the new name for the project wide namespace, click Apply and select what places in your project you'd want it to change, in the new dialog and OK it. Done! :-)

In my case I had created a SB app from the SB Initializer and had included a fair number of deps in it to other things. I went in and commented out the refs to them in the build.gradle file and so was left with:

implementation 'org.springframework.boot:spring-boot-starter-hateoas'
compileOnly 'org.projectlombok:lombok'
developmentOnly 'org.springframework.boot:spring-boot-devtools'
runtimeOnly 'org.hsqldb:hsqldb'
runtimeOnly 'org.postgresql:postgresql'
annotationProcessor 'org.springframework.boot:spring-boot-configuration-processor'
annotationProcessor 'org.projectlombok:lombok'
testImplementation 'org.springframework.boot:spring-boot-starter-test'
testImplementation 'org.springframework.restdocs:spring-restdocs-mockmvc'

as deps. Then my bare-bones SB app was able to build and get running successfully. As I go to try to do things that may need those commented-out libs I will add them back and see what breaks.

if you want to run an update, delete, or insert statement, you should use the ExecuteNonQuery. ExecuteNonQuery returns the number of rows affected by the statement.

How to Set Count On

If you don't know the column names and you want to specify str data type to all columns:

table = pd.read_excel("path_to_filename")
cols = table.columns
conv = dict(zip(cols ,[str] * len(cols)))
table = pd.read_excel("path_to_filename", converters=conv)

You can actually disable all database constraints in a single SQL command and the re-enable them calling another single command. See:

• Can foreign key constraints be temporarily disabled using TSQL?

I am currently working with SQL Server 2005 but I am almost sure that this approach worked with SQL 2000 as well

   SELECT u.* 
        FROM users AS u
        INNER JOIN (
            SELECT p.*,
             @num := if(@id = user_id, @num + 1, 1) as row_number,
             @id := user_id as tmp
            FROM payments AS p,
                 (SELECT @num := 0) x,
                 (SELECT @id := 0) y
            ORDER BY p.user_id ASC, date DESC)
        ON (p.user_id = u.id) and (p.row_number=1)
        WHERE u.package = 1

Solution #1

Since the original question only wants a simplified solution (and not a faster one), here is a one-line solution:

public boolean contains(int[] array, int key) {
    return Arrays.toString(array).matches(".*[\\[ ]" + key + "[\\],].*");
}

Explanation: Javadoc of Arrays.toString() states the result is enclosed in square brackets and adjacent elements are separated by the characters ", " (a comma followed by a space). So we can count on this. First we convert array to a string, and then we check if key is contained in this string. Of course we cannot accept "sub-numbers" (e.g. "1234" contains "23"), so we have to look for patterns where the key is preceded with an opening bracket or a space, and followed by a closing bracket or a comma.

Note: The used regexp pattern also handles negative numbers properly (whose string representation starts with a minus sign).

Solution #2

This solution is already posted but it contains mistakes, so I post the correct solution:

public boolean contains(int[] array, int key) {
    Arrays.sort(array);
    return Arrays.binarySearch(array, key) >= 0;
}

Also this solution has a side effect: it modifies the array (sorts it).

see: http://www.henryalgus.com/reading-binary-files-using-jquery-ajax/ it'll return a blob as a response, which can then be put into filesaver

$rootScope.$broadcast is a convenient way to raise a "global" event which all child scopes can listen for. You only need to use $rootScope to broadcast the message, since all the descendant scopes can listen for it.

The root scope broadcasts the event:

$rootScope.$broadcast("myEvent");

Any child Scope can listen for the event:

$scope.$on("myEvent",function () {console.log('my event occurred');} );

Why we use $rootScope.$broadcast? You can use $watch to listen for variable changes and execute functions when the variable state changes. However, in some cases, you simply want to raise an event that other parts of the application can listen for, regardless of any change in scope variable state. This is when $broadcast is helpful.

If you already have var parent = document.querySelector('.parent'); you can do this to scope the search to parent's children:

parent.querySelector('.child')

This work for me on fresh install of mac osx (sierra):

1. Define current user as owner of shells

sudo chown $(whoami) /etc/shells

2. Add Fish to /etc/shells

sudo echo /usr/local/bin/fish >> /etc/shells

3. Make Fish your default shell with chsh

chsh -s /usr/local/bin/fish

4. Redefine root as owner of shells

sudo chown root /etc/shells

You can't use $('#Id').attr('style',' color:red'); and $('#Id').css('padding-left','20%');
at the same time.
You can either use attr or css but both only works when they are used alone.

$.each( { name: "John", lang: "JS" }, function(i, n){
    alert( "Name: " + i + ", Value: " + n );
});

One way to achieve it, is by map your welcome-file to your controller request path in the web.xml file:

[web.xml]

<web-app ...

<!-- Index -->
<welcome-file-list>
    <welcome-file>home</welcome-file>
</welcome-file-list>

</web-app>

[LoginController.java]

@Controller("loginController")
public class LoginController{

@RequestMapping("/home")
public String homepage2(ModelMap model, HttpServletRequest request, HttpServletResponse response){
    System.out.println("blablabla2");
    model.addAttribute("sigh", "lesigh");
    return "index";
}

You can use all

> all(1:6 %in% 0:36)
[1] TRUE
> all(1:60 %in% 0:36)
[1] FALSE

On a similar note, if you want to check whether any of the elements is TRUE you can use any

> any(1:6 %in% 0:36)
[1] TRUE
> any(1:60 %in% 0:36)
[1] TRUE
> any(50:60 %in% 0:36)
[1] FALSE

Super key: super key is a set of atttibutes in a relation(table).which can define every tupple in the relation(table) uniquely.

Candidate key: we can say minimal super key is candidate key. Candidate is the smallest sub set of super key. And can uniquely define each and every tupple.

This is my way:

internal static class ResourceAccessor
{
    public static Uri Get(string resourcePath)
    {
        var uri = string.Format(
            "pack://application:,,,/{0};component/{1}"
            , Assembly.GetExecutingAssembly().GetName().Name
            , resourcePath
        );

        return new Uri(uri);
    }
}

Usage:

new BitmapImage(ResourceAccessor.Get("Images/1.png"))

A new byte array will automatically be initialized with all zeroes. You don't have to do anything.

The more general approach to initializing with other values, is to use the Arrays class.

import java.util.Arrays;

byte[] bytes = new byte[100];
Arrays.fill( bytes, (byte) 1 );

Here are the steps that worked for me for Ubuntu OS and using nvm

Go to nodejs website and get the last LTS version (for example in your current dater the version will be: x.y.z)

nvm install x.y.z
# In my case current version is: 14.15.4 (and had 14.15.3)

After that, execute nvm list and you will get list of node versions installed by nvm.

Now you need to switch to the default last installed one by executing:

nvm alias default x.y.z

List again or run nvm --version to check:

Update: sometimes even if i go over the steps above it doesn't work, so what i did was removing the symbolic links in /usr/local/bin

cd /usr/local/bin
sudo rm node npm npx

And relink:

sudo ln -s $(which node) /usr/local/bin/node
sudo ln -s $(which npm) /usr/local/bin/npm
sudo ln -s $(which npx) /usr/local/bin/npx

You have a mismatch of two different collations in your table. You can check what collations each column in your table(s) has by using this query:

SELECT
    col.name, col.collation_name
FROM 
    sys.columns col
WHERE
    object_id = OBJECT_ID('YourTableName')

Collations are needed and used when ordering and comparing strings. It's generally a good idea to have a single, unique collation used throughout your database - don't use different collations within a single table or database - you're only asking for trouble....

Once you've settled for one single collation, you can change those tables / columns that don't match yet using this command:

ALTER TABLE YourTableName
  ALTER COLUMN OffendingColumn
    VARCHAR(100) COLLATE Latin1_General_CI_AS NOT NULL

UPDATE: to find the fulltext indices in your database, use this query here:

SELECT
    fti.object_Id,
    OBJECT_NAME(fti.object_id) 'Fulltext index',
    fti.is_enabled,
    i.name 'Index name',
    OBJECT_NAME(i.object_id) 'Table name'
FROM 
    sys.fulltext_indexes fti
INNER JOIN 
    sys.indexes i ON fti.unique_index_id = i.index_id

You can then drop the fulltext index using:

DROP FULLTEXT INDEX ON (tablename)

I wanted to make a version of this that uses $.getJSON() from a separate JSON file.

Demo: here

JavaScript:

$(document).ready(function () {
    "use strict";

    var selectData, $states;

    function updateSelects() {
        var cities = $.map(selectData[this.value], function (city) {
            return $("<option />").text(city);
        });
        $("#city_names").empty().append(cities);
    }

    $.getJSON("updateSelect.json", function (data) {
        var state;
        selectData = data;
        $states = $("#us_states").on("change", updateSelects);
        for (state in selectData) {
            $("<option />").text(state).appendTo($states);
        }
        $states.change();
    });
});

You should be able to use filter: orderBy

orderBy can accept a third option for the reverse flag.

<select ng-option="item.name for item in items | orderBy:'name':true"></select>

Here item is sorted by 'name' property in a reversed order. The 2nd argument can be any order function, so you can sort in any rule.

@see http://docs.angularjs.org/api/ng.filter:orderBy

if your text doesn't spill over two rows then you can do line-height: ; in your CSS, the more line-height you give, the lower on the container it will hold.

Laravel 5.3+ web middleware group is automatically applied to your routes/web.php file by the RouteServiceProvider.

Unless you modify kernel $middlewareGroups array in an unsupported order, probably you are trying to inject requests as a regular dependency from the constructor.

Use request as

public function show(Request $request){

}

instead of

public function __construct(Request $request){

}

I believe that npm install should not run in a production environment. There are several things that can go wrong - npm outage, download of newer dependencies (shrinkwrap seems to have solved this) are two of them.

On the other hand, folder node_modules should not be committed to Git. Apart from their big size, commits including them can become distracting.

The best solutions would be this: npm install should run in a CI environment that is similar to the production environment. All tests will run and a zipped release file will be created that will include all dependencies.

This was asked some time ago now, but based on the answer that @nacho_zona3 provided, and previous experience with fragments, the issue is that the views have not been created by the time you are trying to find them with the findViewById() method in onCreate() to fix this, move the following code:

// 1. get a reference to recyclerView
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.list);

// 2. set layoutManger
recyclerView.setLayoutManager(new LinearLayoutManager(this));

// this is data fro recycler view
ItemData itemsData[] = { new ItemData("Indigo",R.drawable.circle),
        new ItemData("Red",R.drawable.color_ic_launcher),
        new ItemData("Blue",R.drawable.indigo),
        new ItemData("Green",R.drawable.circle),
        new ItemData("Amber",R.drawable.color_ic_launcher),
        new ItemData("Deep Orange",R.drawable.indigo)};


// 3. create an adapter
MyAdapter mAdapter = new MyAdapter(itemsData);
// 4. set adapter
recyclerView.setAdapter(mAdapter);
// 5. set item animator to DefaultAnimator
recyclerView.setItemAnimator(new DefaultItemAnimator()); 

to your fragment's onCreateView() call. A small amount of refactoring is required because all variables and methods called from this method have to be static. The final code should look like:

 public class ColorsFragment extends Fragment {

     public ColorsFragment() {}

     @Override
     public View onCreateView(LayoutInflater inflater, ViewGroup container,
         Bundle savedInstanceState) {

         View rootView = inflater.inflate(R.layout.fragment_colors, container, false);
         // 1. get a reference to recyclerView
         RecyclerView recyclerView = (RecyclerView) rootView.findViewById(R.id.list);

         // 2. set layoutManger
         recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));

         // this is data fro recycler view
         ItemData itemsData[] = {
             new ItemData("Indigo", R.drawable.circle),
                 new ItemData("Red", R.drawable.color_ic_launcher),
                 new ItemData("Blue", R.drawable.indigo),
                 new ItemData("Green", R.drawable.circle),
                 new ItemData("Amber", R.drawable.color_ic_launcher),
                 new ItemData("Deep Orange", R.drawable.indigo)
         };


         // 3. create an adapter
         MyAdapter mAdapter = new MyAdapter(itemsData);
         // 4. set adapter
         recyclerView.setAdapter(mAdapter);
         // 5. set item animator to DefaultAnimator
         recyclerView.setItemAnimator(new DefaultItemAnimator());

         return rootView;
     }
 }

So the main thing here is that anywhere you call findViewById() you will need to use rootView.findViewById()

You can use map lambda

a = [2,3,4]
b = [5,6,7]
c = map(lambda x,y:(x,y),a,b)

This will also work if there lengths of original lists do not match

I had the same problem as you though I have followed a different guide: http://www.mkyong.com/webservices/jax-rs/jersey-hello-world-example/

The strange part is that, in this guide I have used, I should not have any problem with compatibility between versions (1.x against 2.x) because following the guide you use the jersey 1.8.x on pom.xmland in the web.xmlyou refer to a class (com.sun.jersey.spi.container.servlet.ServletContainer) as said before of 1.x version. So as I can infer this should be working.

My guess is because I'm using JDK 1.7 this class does not exist anymore.

After, I tried to resolve with the answers before mine, did not helped, I have made changes on the pom.xmland on the web.xml the error changed to: java.lang.ClassNotFoundException: org.glassfish.jersey.servlet.ServletContainer

Which supposedly should be exist!

As result of this error, I found a "new" solution: http://marek.potociar.net/2013/06/13/jax-rs-2-0-and-jersey-2-0-released/

With Maven (archetypes), generate a jersey project, likes this:

mvn archetype:generate -DarchetypeGroupId=org.glassfish.jersey.archetypes -DarchetypeArtifactId=jersey-quickstart-webapp -DarchetypeVersion=2.0

And it worked for me! :)

I was using Maven in eclipse and I did not want to have an additional copy of the properties file in the root folder. You can do the following in eclipse:

1. Open run dialog (click the little arrow next to the play button and go to run configurations)
2. Go to the "classpath" tab
3. Select the "User Entries" and click the "Advanced" button on the right side.
4. Now select the "Add External folder" radio button.
5. Select the resources folder

Since 12,200 people have looked at this question and not got an answer:

DFSORT and SyncSort are the predominant Mainframe sorting products. Their control cards have many similarities, and some differences.

JOINKEYS FILE=F1,FIELDS=(key1startpos,7,A)              
JOINKEYS FILE=F2,FIELDS=(key2startpos,7,A)              
JOIN UNPAIRED,F1,F2
REFORMAT FIELDS=(F1:1,5200,F2:1,5200)                         
SORT FIELDS=COPY    

A "JOINKEYS" is made of three Tasks. Sub-Task 1 is the first JOINKEYS. Sub-Task 2 is the second JOINKEYS. The Main Task follows and is where the joined data is processed. In the example above it is a simple COPY operation. The joined data will simply be written to SORTOUT.

The JOIN statement defines that as well as matched records, UNPAIRED F1 and F2 records are to be presented to the Main Task.

The REFORMAT statement defines the record which will be presented to the Main Task. A more efficient example, imagining that three fields are required from F2, is:

 REFORMAT FIELDS=(F1:1,5200,F2:1,10,30,1,5100,100)

Each of the fields on F2 is defined with a start position and a length.

The record which is then processed by the Main task is 5311 bytes long, and the fields from F2 can be referenced by 5201,10,5211,1,5212,100 with the F1 record being 1,5200.

A better way achieve the same thing is to reduce the size of F2 with JNF2CNTL.

//JNF2CNTL DD *
  INREC BUILD=(207,1,10,30,1,5100,100)

Some installations of SyncSort do not support JNF2CNTL, and even where supported (from Syncsort MFX for z/OS release 1.4.1.0 onwards), it is not documented by SyncSort. For users of 1.3.2 or 1.4.0 an update is available from SyncSort to provide JNFnCNTL support.

It should be noted that JOINKEYS by default SORTs the data, with option EQUALS. If the data for a JOINKEYS file is already in sequence, SORTED should be specified. For DFSORT NOSEQCHK can also be specified if sequence-checking is not required.

 JOINKEYS FILE=F1,FIELDS=(key1startpos,7,A),SORTED,NOSEQCHK

Although the request is strange, as the source file won't be able to be determined, all unmatched records are to go to a separate output file.

With DFSORT, there is a matching-marker, specified with ? in the REFORMAT:

 REFORMAT FIELDS=(F1:1,5200,F2:1,10,30,1,5100,100,?)

This increases the length of the REFORMAT record by one byte. The ? can be specified anywhere on the REFORMAT record, and need not be specified. The ? is resolved by DFSORT to: B, data sourced from Both files; 1, unmatched record from F1; 2, unmatched record from F2.

SyncSort does not have the match marker. The absence or presence of data on the REFORMAT record has to be determined by values. Pick a byte on both input records which cannot contain a particular value (for instance, within a number, decide on a non-numeric value). Then specify that value as the FILL character on the REFORMAT.

 REFORMAT FIELDS=(F1:1,5200,F2:1,10,30,1,5100,100),FILL=C'$'

If position 1 on F1 cannot naturally have "$" and position 20 on F2 cannot either, then those two positions can be used to establish the result of the match. The entire record can be tested if necessary, but sucks up more CPU time.

The apparent requirement is for all unmatched records, from either F1 or F2, to be written to one file. This will require a REFORMAT statement which includes both records in their entirety:

DFSORT, output unmatched records:

  REFORMAT FIELDS=(F1:1,5200,F2:1,5200,?)

  OUTFIL FNAMES=NOMATCH,INCLUDE=(10401,1,SS,EQ,C'1,2'),
        IFTHEN=(WHEN=(10401,1,CH,EQ,C'1'),
                    BUILD=(1,5200)),
        IFTHEN=(WHEN=NONE,
                    BUILD=(5201,5200))

SyncSort, output unmatched records:

  REFORMAT FIELDS=(F1:1,5200,F2:1,5200),FILL=C'$'

  OUTFIL FNAMES=NOMATCH,INCLUDE=(1,1,CH,EQ,C'$',
                          OR,5220,1,CH,EQ,C'$'),
        IFTHEN=(WHEN=(1,1,CH,EQ,C'$'),
                    BUILD=(1,5200)),
        IFTHEN=(WHEN=NONE,
                    BUILD=(5201,5200))

The coding for SyncSort will also work with DFSORT.

To get the matched records written is easy.

  OUTFIL FNAMES=MATCH,SAVE

SAVE ensures that all records not written by another OUTFIL will be written here.

There is some reformatting required, to mainly output data from F1, but to select some fields from F2. This will work for either DFSORT or SyncSort:

  OUTFIL FNAMES=MATCH,SAVE,
     BUILD=(1,50,10300,100,51,212,5201,10,263,8,5230,1,271,4929)

The whole thing, with arbitrary starts and lengths is:

DFSORT

  JOINKEYS FILE=F1,FIELDS=(1,7,A)              
  JOINKEYS FILE=F2,FIELDS=(20,7,A)    

  JOIN UNPAIRED,F1,F2

  REFORMAT FIELDS=(F1:1,5200,F2:1,5200,?)                         

  SORT FIELDS=COPY    

  OUTFIL FNAMES=NOMATCH,INCLUDE=(10401,1,SS,EQ,C'1,2'),
        IFTHEN=(WHEN=(10401,1,CH,EQ,C'1'),
                    BUILD=(1,5200)),
        IFTHEN=(WHEN=NONE,
                    BUILD=(5201,5200))

  OUTFIL FNAMES=MATCH,SAVE,
     BUILD=(1,50,10300,100,51,212,5201,10,263,8,5230,1,271,4929)

SyncSort

  JOINKEYS FILE=F1,FIELDS=(1,7,A)              
  JOINKEYS FILE=F2,FIELDS=(20,7,A)              

  JOIN UNPAIRED,F1,F2

  REFORMAT FIELDS=(F1:1,5200,F2:1,5200),FILL=C'$'                         

  SORT FIELDS=COPY    

  OUTFIL FNAMES=NOMATCH,INCLUDE=(1,1,CH,EQ,C'$',
                          OR,5220,1,CH,EQ,C'$'),
        IFTHEN=(WHEN=(1,1,CH,EQ,C'$'),
                    BUILD=(1,5200)),
        IFTHEN=(WHEN=NONE,
                    BUILD=(5201,5200))

  OUTFIL FNAMES=MATCH,SAVE,
     BUILD=(1,50,10300,100,51,212,5201,10,263,8,5230,1,271,4929)

I had to make some changes to make it work, as some things seem to have changed in the meantime:

• xjc would complain that my adapter does not extend XmlAdapter
• some bizarre and unneeded imports were drawn in (org.w3._2001.xmlschema)
• the parsing methods must not be static when extending the XmlAdapter, obviously

Here's a working example, hope this helps (I'm using JodaTime but in this case SimpleDate would be sufficient):

import java.util.Date;
import javax.xml.bind.DatatypeConverter;
import javax.xml.bind.annotation.adapters.XmlAdapter;
import org.joda.time.DateTime;

public class DateAdapter extends XmlAdapter<Object, Object> {
    @Override
    public Object marshal(Object dt) throws Exception {
        return new DateTime((Date) dt).toString("YYYY-MM-dd");
    }

    @Override
        public Object unmarshal(Object s) throws Exception {
        return DatatypeConverter.parseDate((String) s).getTime();
    }
}

In the xsd, I have followed the excellent references given above, so I have included this xml annotation:

<xsd:appinfo>
    <jaxb:schemaBindings>
        <jaxb:package name="at.mycomp.xml" />
    </jaxb:schemaBindings>
    <jaxb:globalBindings>
        <jaxb:javaType name="java.util.Date" xmlType="xsd:date"
              parseMethod="at.mycomp.xml.DateAdapter.unmarshal"
          printMethod="at.mycomp.xml.DateAdapter.marshal" />
    </jaxb:globalBindings>
</xsd:appinfo>

You are getting Floating point exception because Number % i, when i is 0:

int Is_Prime( int Number ){

  int i ;

  for( i = 0 ; i < Number / 2 ; i++ ){

    if( Number % i != 0 ) return -1 ;

  }

  return Number ;

}

Just start the loop at i = 2. Since i = 1 in Number % i it always be equal to zero, since Number is a int.

Javadoc to the rescue :

A Scanner breaks its input into tokens using a delimiter pattern, which by default matches whitespace

nextLine is probably the method you should use.

What fixed this for me was that I had a React component being rendered prior to my core.js shim being loaded.

import ReactComponent from '.'
import 'core-js/es6'

Loading the core-js prior to the ReactComponent fixed my issue

import 'core-js/es6'
import ReactComponent from '.'

They don't exist in MySQL do they? Just use a temp table:

CREATE PROCEDURE my_proc () BEGIN 

CREATE TEMPORARY TABLE TempTable (myid int, myfield varchar(100)); 
INSERT INTO TempTable SELECT tblid, tblfield FROM Table1; 

/* Do some more stuff .... */

From MySQL here

"You can use the TEMPORARY keyword when creating a table. A TEMPORARY table is visible only to the current connection, and is dropped automatically when the connection is closed. This means that two different connections can use the same temporary table name without conflicting with each other or with an existing non-TEMPORARY table of the same name. (The existing table is hidden until the temporary table is dropped.)"

Note: Svg does not work for android release versions so do not consider for android. It will work for android in debug mode only. But it works fine for ios.

Use https://github.com/vault-development/react-native-svg-uri

Install

npm install react-native-svg-uri --save
react-native link react-native-svg # not react-native-svg-uri

Usage

import SvgUri from 'react-native-svg-uri';


<SvgUri source={require('./path_to_image/image.svg')} />

You could use TidyNet.Tidy to convert the HTML to XHTML, and then use an XML parser.

Another alternative would be to use the builtin engine mshtml:

using mshtml;
...
object[] oPageText = { html };
HTMLDocument doc = new HTMLDocumentClass();
IHTMLDocument2 doc2 = (IHTMLDocument2)doc;
doc2.write(oPageText);

This allows you to use javascript-like functions like getElementById()

I'm not sure there's a clear-cut definition of "framework". Sometimes a large set of libraries is called a framework, but I think the typical use of the word is closer to the definition aioobe brought.

This very nice article sums up the difference between just a set of libraries and a framework:

A framework can be defined as a set of libraries that say “Don’t call us, we’ll call you.”

How does a framework help you? Because instead of writing something from scratch, you basically just extend a given, working application. You get a lot of productivity this way - sometimes the resulting application can be far more elaborate than you could have done on your own in the same time frame - but you usually trade in a lot of flexibility.

From what I can gather, the model doesn't want to guess whether checked = true or false, I got around this by setting a value attribute on the checkbox element with jQuery before submitting the form like this:

 $('input[type="checkbox"]').each(function () {
       $(this).attr('value', $(this).is(':checked'));
 }); 

This way, you don't need a hidden element just to store the value of the checkbox.

If you want another way:

"ayy: This will store the line in buffer a.

"ap: This will put the contents of buffer a at the cursor.

There are many variations on this.

"a5yy: This will store the 5 lines in buffer a.

See "Vim help files for more fun.

Alternatively to information_schema it is possible to use pg_tables:

select * from pg_tables where schemaname='public';

you can create a shallow clone to only get the last few revisions:

 git clone --depth 1 git://url

then either simply delete the .git directory or use git archive to export your tree.

Answer from Varun Rathore is OK but you must consider that starting from Windows Server 2008 R2 and higher the SQLServer service will run under a local virtual account and not anymore under the old well known "NETWORK SERVICE". Due to this, to switch a newly attached DB to "not read only mode", you must setup permissions on the ldf and mdf files for local machine user line "NT SERVICE\MSSQLSERVER" where MSSQLSERVER would be the service name in a pretty standard installation.

Checkout this https://docs.microsoft.com/en-us/sql/database-engine/configure-windows/configure-windows-service-accounts-and-permissions#VA_Desc for details configuring service permissions

In ES2015, using the shorthand property declaration syntax for object literals, you can log objects while also concisely preserving your variable names:

console.log("bwib:", bwib, "bwab:", bwab, "bwob": bwob) // old way A
console.log({bwib: bwib, bwab: bwab, bwob: bwob})       // old way B

console.log({bwib, bwab, bwob})                         // ES2015+ way

I hope this will work

Till this date I also used to think that we need to create that /data/db folder for starting mongod command.

But recently I tried to start mongod with service command and it worked for me and there was no need to create /data/db directory.

service mongod start

As to check the status of mongod you can run the following command.

service mongod status

I tried most of the answers here nothing seems to work in my case. So i changed the Temp location in my env variables to C:\npm. Then it started to work. This is not a good idea but a temporary solution.

ExPanDaR’s package function prepare_missing_values_graph can be used to explore panel data:

If array of Books is null, return zero as it looks that method count total price of all Books provided - if no Book is provided, zero is correct value:

public static double calculateInventoryTotal(Book[] books)
{
if(books == null) return 0;
    double total = 0;
    for (int i = 0; i < books.length; i++)
    {
        total += books[i].getPrice();
    }
    return total;
}

It's upon to you to decide if it's correct that you can input null input value (shoul not be correct, but...).

There is no limit. It only depends on your free memory and system maximum file size. But that doesn't mean you shouldn't take precautionary measure in tackling memory usage in your database. Always create a script that can delete rows that are out of use or that will keep total no of rows within a particular figure, say a thousand.

I use both because sometimes they give different, useful error messages.

The Python project was able to find and fix a number of small buglets when one of the core developers first tried compiling with clang.

Good question... I find that coders typically use the declaration to declare defaults. I've been held to one way (or warned) or the other too based on the compiler

void testFunct(int nVal1, int nVal2=500);
void testFunct(int nVal1, int nVal2)
{
    using namespace std;
    cout << nVal1 << << nVal2 << endl;
}

I had a similar issue with Spring Data MongoDB: I had to add the package path to @EnableMongoRepositories

Both are effectively the same class (you can look at the disassembly). HashTable was created first before .Net had generics. Dictionary, however is a generic class and gives you strong typing benefits. I would never use HashTable since Dictionary costs you nothing to use.
