Adding to exebook's response, the mathematics usage of the keyword let also encapsulates well the scoping implications of let when used in Javascript/ES6. Specifically, just as the following ES6 code is not aware of the assignment in braces of toPrint when it prints out the value of 'Hello World',

let toPrint = 'Hello World.';
{
    let toPrint = 'Goodbye World.';
}
console.log(toPrint); // Prints 'Hello World'

let as used in formalized mathematics (especially the writing of proofs) indicates that the current instance of a variable exists only for the scope of that logical idea. In the following example, x immediately gains a new identity upon entering the new idea (usually these are concepts necessary to prove the main idea) and reverts immediately to the old x upon the conclusion of the sub-proof. Of course, just as in coding, this is considered somewhat confusing and so is usually avoided by choosing a different name for the other variable.

Let x be so and so...

  Proof stuff

 New Idea { Let x be something else ... prove something } Conclude New Idea

 Prove main idea with old x

Check this link in MDN

let x = 1;

if (x === 1) {
let x = 2;

console.log(x);
// expected output: 2
}

console.log(x);
// expected output: 1

I guess that OracleBulkCopy is one of the fastest ways. I had some trouble to learn, that I needed a new ODAC version. Cf. Where is type [Oracle.DataAccess.Client.OracleBulkCopy] ?

Here is the complete PowerShell code to copy from a query into a suited existing Oracle table. I tried Sql-Server a datasource, but other valid OLE-DB sources will go to.

if ($ora_dll -eq $null)
{
    "Load Oracle dll"
    $ora_dll = [System.Reflection.Assembly]::LoadWithPartialName("Oracle.DataAccess") 
    $ora_dll
}

# sql-server or Oracle source example is sql-server
$ConnectionString ="server=localhost;database=myDatabase;trusted_connection=yes;Provider=SQLNCLI10;"

# Oracle destination
$oraClientConnString = "Data Source=myTNS;User ID=myUser;Password=myPassword"

$tableName = "mytable"
$sql = "select * from $tableName"

$OLEDBConn = New-Object System.Data.OleDb.OleDbConnection($ConnectionString)
$OLEDBConn.open()
$readcmd = New-Object system.Data.OleDb.OleDbCommand($sql,$OLEDBConn)
$readcmd.CommandTimeout = '300'
$da = New-Object system.Data.OleDb.OleDbDataAdapter($readcmd)
$dt = New-Object system.Data.datatable
[void]$da.fill($dt)
$OLEDBConn.close()
#Write-Output $dt

if ($dt)
{
    try
    {
        $bulkCopy = new-object ("Oracle.DataAccess.Client.OracleBulkCopy") $oraClientConnString
        $bulkCopy.DestinationTableName = $tableName
        $bulkCopy.BatchSize = 5000
        $bulkCopy.BulkCopyTimeout = 10000
        $bulkCopy.WriteToServer($dt)
        $bulkcopy.close()
        $bulkcopy.Dispose()
    }
    catch
    {
        $ex = $_.Exception
        Write-Error "Write-DataTable$($connectionName):$ex.Message"
        continue
    }
}

BTW: I use this to copy table with CLOB columns. I didn't get that to work using linked servers cf. question on dba. I didn't retry linked serves with the new ODAC.

By default for development JVM uses small size and small config for other performance related features. But for production you can tune e.g. (In addition it Application Server specific config can exist) -> (If there still isn't enough memory to satisfy the request and the heap has already reached the maximum size, an OutOfMemoryError will occur)

-Xms<size>        set initial Java heap size
-Xmx<size>        set maximum Java heap size
-Xss<size>        set java thread stack size

-XX:ParallelGCThreads=8
-XX:+CMSClassUnloadingEnabled
-XX:InitiatingHeapOccupancyPercent=70
-XX:+UnlockDiagnosticVMOptions
-XX:+UseConcMarkSweepGC
-Xms512m
-Xmx8192m
-XX:MaxPermSize=256m (in java 8 optional)

For example: On linux Platform for production mode preferable settings.

After downloading and configuring server with this way http://www.ehowstuff.com/how-to-install-and-setup-apache-tomcat-8-on-centos-7-1-rhel-7/

1.create setenv.sh file on folder /opt/tomcat/bin/

   touch /opt/tomcat/bin/setenv.sh

2.Open and write this params for setting preferable mode.

nano  /opt/tomcat/bin/setenv.sh 

export CATALINA_OPTS="$CATALINA_OPTS -XX:ParallelGCThreads=8"
export CATALINA_OPTS="$CATALINA_OPTS -XX:+CMSClassUnloadingEnabled"
export CATALINA_OPTS="$CATALINA_OPTS -XX:InitiatingHeapOccupancyPercent=70"
export CATALINA_OPTS="$CATALINA_OPTS -XX:+UnlockDiagnosticVMOptions"
export CATALINA_OPTS="$CATALINA_OPTS -XX:+UseConcMarkSweepGC"
export CATALINA_OPTS="$CATALINA_OPTS -Xms512m"
export CATALINA_OPTS="$CATALINA_OPTS -Xmx8192m"
export CATALINA_OPTS="$CATALINA_OPTS -XX:MaxMetaspaceSize=256M"

Note that the JVM uses more memory than just the heap. For example Java methods, thread stacks and native handles are allocated in memory separate from the heap, as well as JVM internal data structures.

IE does not support for(i in obj) for native properties. Here is a list of all the props I could find.

It seems stackoverflow does some stupid filtering.

The list is available at the bottom of this google group post:- https://groups.google.com/group/hackvertor/browse_thread/thread/a9ba81ca642a63e0

If MouseEvent.offsetX is supported by your browser (all major browsers actually support it), The jQuery Event object will contain this property.

The MouseEvent.offsetX read-only property provides the offset in the X coordinate of the mouse pointer between that event and the padding edge of the target node.

$("#seek-bar").click(function(event) {
  var x = event.offsetX
  alert(x);    
});

For reactive form, I managed to make it work by using the following example (47 can be replaced with other value or variable):

<div [formGroup]="form">
  <select formControlName="fieldName">
    <option
        *ngFor="let option of options; index as i"
        [selected]="option === 47"
    >
        {{ option }}
    </option>
  </select>
</div>

Combining CodeIgniter and JavaScript:

//for using the base_url() function
$this->load->helper('url');

echo "<script type='javascript/text'>";
echo "alert('There are no fields to generate a report');"
echo "window.location.href = '" . base_url() . "admin/ahm/panel';"
echo "</script>";

Note: The redirect() function automatically includes the base_url path that is why it wasn't required there.

You can also use update ... from syntax and use a mapping table. If you want to update more than one column, it's much more generalizable:

update test as t set
    column_a = c.column_a
from (values
    ('123', 1),
    ('345', 2)  
) as c(column_b, column_a) 
where c.column_b = t.column_b;

You can add as many columns as you like:

update test as t set
    column_a = c.column_a,
    column_c = c.column_c
from (values
    ('123', 1, '---'),
    ('345', 2, '+++')  
) as c(column_b, column_a, column_c) 
where c.column_b = t.column_b;

        for(int j = 0; j < 10000; j++) {
            sb.append("a really, really long string");
        }
        String str = sb.toString();
        for (int testscount = 0; testscount < 10; testscount ++) {


            //Test 1
            long start = System.currentTimeMillis();
            for(int c = 0; c < 10000000; c++) {
                for (int i = 0, n = str.length(); i < n; i++) {
                    char chr = str.charAt(i);
                    doSomethingWithChar(chr);//To trick JIT optimistaion
                }
            }

            System.out.println("1: " + (System.currentTimeMillis() - start));

            //Test 2
            start = System.currentTimeMillis();
            char[] chars = str.toCharArray();
            for(int c = 0; c < 10000000; c++) {
                for (int i = 0, n = chars.length; i < n; i++) {
                    char chr = chars[i];

                }
            }
            System.out.println("2: " + (System.currentTimeMillis() - start));
            System.out.println();
        }


    }


    public static void doSomethingWithChar(char chr) {
        int newInt = chr << 2;
    }

For long strings I'll chose the first one. Why copy around long strings? Documentations says:

public char[] toCharArray() Converts this string to a new character array.

Returns: a newly allocated character array whose length is the length of this string and whose contents are initialized to contain the character sequence represented by this string.

//Edit 1

I've changed the test to trick JIT optimisation.

//Edit 2

Repeat test 10 times to let JVM warm up.

//Edit 3

Conclusions:

First of all str.toCharArray(); copies entire string in memory. It can be memory consuming for long strings. Method String.charAt( ) looks up char in char array inside String class checking index before. It looks like for short enough Strings first method (i.e. chatAt method) is a bit slower due to this index check. But if the String is long enough, copying whole char array gets slower, and the first method is faster. The longer the string is, the slower toCharArray performs. Try to change limit in for(int j = 0; j < 10000; j++) loop to see it. If we let JVM warm up code runs faster, but proportions are the same.

After all it's just micro-optimisation.

Seriously, the top answer is not working for me. tried cxf.version 2.4.1 and 3.0.10. and generate absolute path with wsdlLocation every times.

My solution is to use the wsdl2java command in the apache-cxf-3.0.10\bin\ with -wsdlLocation classpath:wsdl/QueryService.wsdl.

Detail:

    wsdl2java -encoding utf-8 -p com.jeiao.boss.testQueryService -impl -wsdlLocation classpath:wsdl/testQueryService.wsdl http://127.0.0.1:9999/platf/testQueryService?wsdl

If you created your project with Spring Initializr, everything should be configured correctly and all you need to do is run...

./gradlew clean test --info

• Use --info if you want to see test output.
• Use clean if you want to re-run tests that have already passed since the last change.

Dependencies required in build.gradle for testing in Spring Boot...

dependencies {
    compile('org.springframework.boot:spring-boot-starter')
    testCompile('org.springframework.boot:spring-boot-starter-test')
}

For some reason the test runner doesn't tell you this, but it produces an HTML report in build/reports/tests/test/index.html.

import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.concurrent.TimeUnit;

public class MyTest {

    public static void main(String[] args) {
        long seconds = 360000;

        long days = TimeUnit.SECONDS.toDays(seconds);
        long hours = TimeUnit.SECONDS.toHours(seconds - TimeUnit.DAYS.toSeconds(days));

        System.out.println("days: " + days);
        System.out.println("hours: " + hours);
    }
}

I've investigated this issue, referring to the LayoutInflater docs and setting up a small sample demonstration project. The following tutorials shows how to dynamically populate a layout using LayoutInflater.

Before we get started see what LayoutInflater.inflate() parameters look like:

• resource: ID for an XML layout resource to load (e.g., R.layout.main_page)
• root: Optional view to be the parent of the generated hierarchy (if attachToRoot is true), or else simply an object that provides a set of LayoutParams values for root of the returned hierarchy (if attachToRoot is false.)

• attachToRoot: Whether the inflated hierarchy should be attached to the root parameter? If false, root is only used to create the correct subclass of LayoutParams for the root view in the XML.

• Returns: The root View of the inflated hierarchy. If root was supplied and attachToRoot is true, this is root; otherwise it is the root of the inflated XML file.

Now for the sample layout and code.

Main layout (main.xml):

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

Added into this container is a separate TextView, visible as small red square if layout parameters are successfully applied from XML (red.xml):

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="25dp"
    android:layout_height="25dp"
    android:background="#ff0000"
    android:text="red" />

Now LayoutInflater is used with several variations of call parameters

public class InflaterTest extends Activity {

    private View view;

    @Override
    public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);

      setContentView(R.layout.main);
      ViewGroup parent = (ViewGroup) findViewById(R.id.container);

      // result: layout_height=wrap_content layout_width=match_parent
      view = LayoutInflater.from(this).inflate(R.layout.red, null);
      parent.addView(view);

      // result: layout_height=100 layout_width=100
      view = LayoutInflater.from(this).inflate(R.layout.red, null);
      parent.addView(view, 100, 100);

      // result: layout_height=25dp layout_width=25dp
      // view=textView due to attachRoot=false
      view = LayoutInflater.from(this).inflate(R.layout.red, parent, false);
      parent.addView(view);

      // result: layout_height=25dp layout_width=25dp 
      // parent.addView not necessary as this is already done by attachRoot=true
      // view=root due to parent supplied as hierarchy root and attachRoot=true
      view = LayoutInflater.from(this).inflate(R.layout.red, parent, true);
    }
}

The actual results of the parameter variations are documented in the code.

SYNOPSIS: Calling LayoutInflater without specifying root leads to inflate call ignoring the layout parameters from the XML. Calling inflate with root not equal null and attachRoot=true does load the layout parameters, but returns the root object again, which prevents further layout changes to the loaded object (unless you can find it using findViewById()). The calling convention you most likely would like to use is therefore this one:

loadedView = LayoutInflater.from(context)
                .inflate(R.layout.layout_to_load, parent, false);

To help with layout issues, the Layout Inspector is highly recommended.

As Kristian has pointed out, good control over z-values will often solve your problems.

If that does not work you can take a look at CSS Box Shadow Bottom Only on using overflow hidden to hide excess shadow.

I would also have in mind that the box-shadow property can accept a comma-separated list of shadows like this:

box-shadow: 0px 10px 5px #888, 0px -10px 5px #888;

This will give you some control over the "amount" of shadow in each direction.

Have a look at http://www.css3.info/preview/box-shadow/ for more information about box-shadow.

Hope this was what you were looking for!

You could use *ngIf="teamMembers != 0" to check whether data is present

To check for duplicates you need to compare distinct pairs.

A great search engine for special characters that I recenetly found: amp-what?

You can even search by object name, like "arrow", "chess", etc...

For the android dev minimalists: Log.getStackTraceString(exception)

1. Do a right click->properties on the file in Visual Studio.
2. Set the Copy to Output Directory to Copy always.

Then you will be able to reference your files by using a path such as @".\my_html.html"

Copy to Output Directory will put the file in the same folder as your binary dlls when the project is built. This works with any content file, even if its in a sub folder.

If you use a sub folder, that too will be copied in to the bin folder so your path would then be @".\my_subfolder\my_html.html"

In order to create a URI you can use locally (instead of served via the web), you'll need to use the file protocol, using the base directory of your binary - note: this will only work if you set the Copy to Ouptut Directory as above or the path will not be correct.

This is what you need:

string curDir = Directory.GetCurrentDirectory();
this.webBrowser1.Url = new Uri(String.Format("file:///{0}/my_html.html", curDir));

You'll have to change the variables and names of course.

You can use Simpsons rule or the Trapezium rule to calculate the area under a graph given a table of y-values at a regular interval.

Python script that calculates Simpsons rule:

def integrate(y_vals, h):
    i = 1
    total = y_vals[0] + y_vals[-1]
    for y in y_vals[1:-1]:
        if i % 2 == 0:
            total += 2 * y
        else:
            total += 4 * y
        i += 1
    return total * (h / 3.0)

h is the offset (or gap) between y values, and y_vals is an array of well, y values.

Example (In same file as above function):

y_values = [13, 45.3, 12, 1, 476, 0]
interval = 1.2
area = integrate(y_values, interval)
print("The area is", area)

If you don't want to use any external polyfill library, you can use this function provided by the Mozilla Developer Network website:

Add reference to add System.Configuration:-

System.Configuration.ConfigurationManager.
    ConnectionStrings["connectionStringName"].ConnectionString;

Also you can change the WebConfig file to include the provider name:-

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

You can also use the line separator character in String.format (See java.util.Formatter), which is also platform agnostic.

i.e.:

result.append(String.format("%n", ""));

If you need to add more line spaces, just use:

result.append(String.format("%n%n", ""));

You can also use StringFormat to format your entire string, with a newline(s) at the end.

result.append(String.format("%10s%n%n", "This is my string."));

I have just noticed that Bjarne Stroustrup labels % as the remainder operator, not the modulo operator.

I would bet that this is its formal name in the ANSI C & C++ specifications, and that abuse of terminology has crept in. Does anyone know this for a fact?

But if this is the case then C's fmodf() function (and probably others) are very misleading. they should be labelled fremf(), etc

Program Debug Database file (pdb) is a file format by Microsoft for storing debugging information.

When you build a project using Visual Studio or command prompt the compiler creates these symbol files.

A "sort merge" join is performed by sorting the two data sets to be joined according to the join keys and then merging them together. The merge is very cheap, but the sort can be prohibitively expensive especially if the sort spills to disk. The cost of the sort can be lowered if one of the data sets can be accessed in sorted order via an index, although accessing a high proportion of blocks of a table via an index scan can also be very expensive in comparison to a full table scan.

A hash join is performed by hashing one data set into memory based on join columns and reading the other one and probing the hash table for matches. The hash join is very low cost when the hash table can be held entirely in memory, with the total cost amounting to very little more than the cost of reading the data sets. The cost rises if the hash table has to be spilled to disk in a one-pass sort, and rises considerably for a multipass sort.

(In pre-10g, outer joins from a large to a small table were problematic performance-wise, as the optimiser could not resolve the need to access the smaller table first for a hash join, but the larger table first for an outer join. Consequently hash joins were not available in this situation).

The cost of a hash join can be reduced by partitioning both tables on the join key(s). This allows the optimiser to infer that rows from a partition in one table will only find a match in a particular partition of the other table, and for tables having n partitions the hash join is executed as n independent hash joins. This has the following effects:

1. The size of each hash table is reduced, hence reducing the maximum amount of memory required and potentially removing the need for the operation to require temporary disk space.
2. For parallel query operations the amount of inter-process messaging is vastly reduced, reducing CPU usage and improving performance, as each hash join can be performed by one pair of PQ processes.
3. For non-parallel query operations the memory requirement is reduced by a factor of n, and the first rows are projected from the query earlier.

You should note that hash joins can only be used for equi-joins, but merge joins are more flexible.

In general, if you are joining large amounts of data in an equi-join then a hash join is going to be a better bet.

This topic is very well covered in the documentation.

If your function resides in an mvc controller u can use the below code with a dictionary object of what you want to convert to json

Json(someDictionaryObj, JsonRequestBehavior.AllowGet);

Also try and look at system.web.script.serialization.javascriptserializer if you are using .net 3.5

as for your web request...it seems ok at first glance..

I would use something like this..

public void WebRequestinJson(string url, string postData)
    {
    StreamWriter requestWriter;

    var webRequest = System.Net.WebRequest.Create(url) as HttpWebRequest;
    if (webRequest != null)
    {
        webRequest.Method = "POST";
        webRequest.ServicePoint.Expect100Continue = false;
        webRequest.Timeout = 20000;

        webRequest.ContentType = "application/json";
        //POST the data.
        using (requestWriter = new StreamWriter(webRequest.GetRequestStream()))
        {
            requestWriter.Write(postData);
        }
    }
}

May be you can make the post and json string a parameter and use this as a generic webrequest method for all calls.

Geocoding is the process of converting addresses (like "1600 Amphitheatre Parkway, Mountain View, CA") into geographic coordinates (like latitude 37.423021 and longitude -122.083739), which you can use to place markers or position the map.

Would this be what you are looking for: Contains sample code

You can now specify the port in the .angular-cli.json under the defaults:

"defaults": {
  "styleExt": "scss",
  "serve": {
    "port": 8080
  },
  "component": {}
}

Tested in angular-cli v1.0.6

An alternative I haven't seen as answer yet is the java.io.PrintWriter.

StringWriter stringWriter = new StringWriter();
PrintWriter writer = new PrintWriter(stringWriter);
writer.println("It was the best of times, it was the worst of times");
writer.println("it was the age of wisdom, it was the age of foolishness,");
writer.println("it was the epoch of belief, it was the epoch of incredulity,");
writer.println("it was the season of Light, it was the season of Darkness,");
writer.println("it was the spring of hope, it was the winter of despair,");
writer.println("we had everything before us, we had nothing before us");
String string = stringWriter.toString();

Also the fact that java.io.BufferedWriter has a newLine() method is unmentioned.

Lot of good answers, here is another way to clean up a string of numbers, is not deleting chars but by moving the numbers out.

string str("(555) 555-5555"), clean;
for (char c : str)
    if (c >= 48 and c <= 57)
        clean.push_back(c);

v.Dt is likely not a Date() object.

See http://jsfiddle.net/southerd/xG2t8/

but in your controller:

scope.v.Dt = Date.parse(scope.v.Dt);

The traditional way to transform a string to a UTF-8 string is as follows:

StrConv("hello world",vbFromUnicode)

So put simply:

Dim fnum As Integer
fnum = FreeFile
Open "myfile.txt" For Output As fnum
Print #fnum, StrConv("special characters: äöüß", vbFromUnicode)
Close fnum

No special COM objects required

You can pass the id as part of the routeValues parameter of the RedirectToAction() method.

return RedirectToAction("Action", new { id = 99 });

This will cause a redirect to Site/Controller/Action/99. No need for temp or any kind of view data.

I had problems correctly displaying some symbols with regular download as pdf. So downloaded as tex jupyter nbconvert --to latex "my notebook.ipynb", made some tweaks with notepad (as an example, in my case I needed these lines for my language

\usepackage{tgpagella}
\usepackage[lithuanian,english]{babel}

) and then exported to pdf with latex --output-format=pdf "my notebook.tex".

But finally, however, to retain the same characters as you see in a browser I ended up using my Chrome browser printing: Ctrl+P Print to pdf. It adds unnecessary header and footer but everything else remains as it is. No more errors processing tqdm progress bar, no more code going out of the page and so on. Simple as that.

const setTimeoutAsync = (cb, delay) =>
  new Promise((resolve) => {
    setTimeout(() => {
      resolve(cb());
    }, delay);
  });

We can pass custom 'cb fxn' like this one

I created a button...

This is where you've gone wrong. You haven't created a button, you've created an anchor element. If you had used a button element instead, you wouldn't have this problem:

<button type="button" data-toggle="modal" data-target="#myModal" data-role="disabled">
    Connect
</button>

If you are going to continue using an a element instead, at the very least you should give it a role attribute set to "button" and drop the href attribute altogether:

<a role="button" ...>

Once you've done that you can introduce a piece of JavaScript which calls event.preventDefault() - here with event being your click event.

Attention: You need to specify -- key, and than --with-mysql-config=/usr/local/mysql/bin/mysql_config

Since ant 1.9.1 you can use a if:set condition : https://ant.apache.org/manual/ifunless.html

Now you can do it with the GitHub Desktop application.

After launching the application

1. Click on the project containing the branch

2. Switch to the branch you would like to delete

   

3. From the "Branch" menu, select, "Unpublish...", to have the branch deleted from the GitHub servers.

   

4. From the "Branch" menu, select, 'Delete "branch_name"...', to have the branch deleted off of your local machine (AKA the machine you are currently working on)

   

This one worked for me:

sudo mv /usr/bin/php /usr/bin/~php
sudo ln -s /Application/XAMPP/xamppfiles/bin/php /usb/bin/php

Git Remote repository file deletion simple solution:

git commit  (file name with path which you want to delete)  -m "file is deleted"

git push

It will work.Multiple selective file also you can delete in remote repository same way.

In Eclipse 3.3:

It's installed under your Eclipse workspace. Something like:

.metadata\.plugins\org.eclipse.core.resources\.projects\

within your workspace folder.

Under that folder is one folder per project. There's a file in there called .location, but it's binary.

So it looks like you can't do what you want, without interacting w/ Eclipse programmatically.

Query to achieve your requirment

SELECT id,GROUP_CONCAT(text SEPARATOR ' ') AS text FROM table_name group by id;

Install Fake Sendmail (download sendmail.zip). Then configure C:\wamp\sendmail\sendmail.ini:

smtp_server=smtp.gmail.com
smtp_port=465
[email protected]
auth_password=your_password

The above will work against a Gmail account. And then configure php.ini:

sendmail_path = "C:\wamp\sendmail\sendmail.exe -t"

Now, restart Apache, and that is basically all you need to do.

On Windows:

CHDIR Displays the name of or changes the current directory.

In Linux:

PWD Displays the name of current directory.

Vinay (above) gave an effective work-around. What's actually causing the button's OnClick event to not work following the OnClientClick event function is that MS has defined it where, once the button is disabled (in the function called by the OnClientClick event), the button "honors" this by not trying to complete the button's activity by calling the OnClick event's defined method.

I struggled several hours trying to figure this out. Once I removed the statement to disable the submit button (that was inside the OnClientClick function), the OnClick method was called with no further problem.

Microsoft, if you're listening, once the button is clicked it should complete it's assigned activity even if it is disabled part of the way through this activity. As long as it is not disabled when it is clicked, it should complete all assigned methods.

refer to http://www.w3schools.com/php/php_mysql_select.asp . If you are a beginner and want to learn, w3schools is a good place.

<?php
    $con=mysqli_connect("localhost","root","YOUR_PHPMYADMIN_PASSWORD","hrmwaitrose");
    // Check connection
    if (mysqli_connect_errno())
      {
      echo "Failed to connect to MySQL: " . mysqli_connect_error();
      }

    $result = mysqli_query($con,"SELECT * FROM employee");

    while($row = mysqli_fetch_array($result))
      {
      echo $row['FirstName'] . " " . $row['LastName']; //these are the fields that you have stored in your database table employee
      echo "<br />";
      }

    mysqli_close($con);
    ?>

You can similarly echo it inside your table

<?php
 echo "<table>";
 while($row = mysqli_fetch_array($result))
          {
          echo "<tr><td>" . $row['FirstName'] . "</td><td> " . $row['LastName'] . "</td></tr>"; //these are the fields that you have stored in your database table employee
          }
 echo "</table>";
 mysqli_close($con);
?>

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

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

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

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

Helpful quote from the git-rm man page

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

If the child entity is used readonly, then it's possible to simply lie and set optional=false. Then ensure that every use of that mapped entity is preloaded via queries.

public class App {
  ...
  @OneToOne(mappedBy = "app", fetch = FetchType.LAZY, optional = false)
  private Attributes additional;

and

String sql = " ... FROM App a LEFT JOIN FETCH a.additional aa ...";

... maybe even persisting would work...

This one is much easie.

Threading.Thread.Sleep(3000)

Another advantage of CXF: it connects to web servers using NTLMV2 authentication out of the box. (used by Windows 2008 & up) Before using CXF, I hacked Axis2 to use HTTPClient V4 + JCIFS to make this possible.

There is another way to do that without cast:

when(a.method(Matchers.<Class<A>>any())).thenReturn(b);

This solution forces the method any() to return Class<A> type and not its default value (Object).

While there isn't anything you can do about the box in some circumstances, you can intercept someone clicking on a link. For me, this was worth the effort for most scenarios and as a fallback, I've left the unload event.

I've used Boxy instead of the standard jQuery Dialog, it is available here: http://onehackoranother.com/projects/jquery/boxy/

$(':input').change(function() {
    if(!is_dirty){
        // When the user changes a field on this page, set our is_dirty flag.
        is_dirty = true;
    }
});

$('a').mousedown(function(e) {
    if(is_dirty) {
        // if the user navigates away from this page via an anchor link, 
        //    popup a new boxy confirmation.
        answer = Boxy.confirm("You have made some changes which you might want to save.");
    }
});

window.onbeforeunload = function() {
if((is_dirty)&&(!answer)){
            // call this if the box wasn't shown.
    return 'You have made some changes which you might want to save.';
    }
};

You could attach to another event, and filter more on what kind of anchor was clicked, but this works for me and what I want to do and serves as an example for others to use or improve. Thought I would share this for those wanting this solution.

I have cut out code, so this may not work as is.

Found that in .Net Core, placing the favicon.ico in /lib rather than wwwroot fixes the issue

If route is not defined, then check web.php routing file.

Route::get('/map', 'NavigationController@map')->name('map'); // note the name() method.

Then you can use this method in the views:

<a class="nav-link" href="{{ route('map') }}">{{ __('Map') }}</a>

PS: the __('Map') is to translate "Map" to the current language.

And the list of names for routes you can see with artisan command:

php artisan route:list

Example 1 is for asp.net applications using forms authenication. This is common practice for internet applications because user is unauthenticated until it is authentcation against some security module.

Example 2 is for asp.net application using windows authenication. Windows Authentication uses Active Directory to authenticate users. The will prevent access to your application. I use this feature on intranet applications.

Try

location ~ ^/(first/location|second/location)/ {
  ...
}

The ~ means to use a regular expression for the url. The ^ means to check from the first character. This will look for a / followed by either of the locations and then another /.

Quoting the Forms Page in the HTML manual:

Buttons created with the BUTTON element function just like buttons created with the INPUT element, but they offer richer rendering possibilities: the BUTTON element may have content. For example, a BUTTON element that contains an image functions like and may resemble an INPUT element whose type is set to "image", but the BUTTON element type allows content.

If you get this, the app has installed on your device. You have to tap the icon. It will ask you if you really want to run it. Say “yes” and then Build & Run again.

By setting the CSS max-width property to 100%, an image will fill the width of it's parenting element, but won’t render larger than it's actual size, thus preserving resolution.

Setting the height property to auto maintains the aspect ratio of the image, using this technique allows static height to be overridden and enables the image to flex proportionally in all directions.

img {
    max-width: 100%;
    height: auto;      
}

td:nth-of-type(n) { padding-right: 10px;}

it will adjust auto space between all td

Answer

You can't according to the PHP manual:

Once the cookies have been set, they can be accessed on the next page load with the $_COOKIE or $HTTP_COOKIE_VARS arrays.

This is because cookies are sent in response headers to the browser and the browser must then send them back with the next request. This is why they are only available on the second page load.

Work around

But you can work around it by also setting $_COOKIE when you call setcookie():

if(!isset($_COOKIE['lg'])) {
    setcookie('lg', 'ro');
    $_COOKIE['lg'] = 'ro';
}
echo $_COOKIE['lg'];

This is so many worlds of bad, because your question implies that you probably have gaping SQL injection holes in your application.

You should be using parameterized statements. For Java, use PreparedStatement with placeholders. You say you don't want to use parameterised statements, but you don't explain why, and frankly it has to be a very good reason not to use them because they're the simplest, safest way to fix the problem you are trying to solve.

See Preventing SQL Injection in Java. Don't be Bobby's next victim.

There is no public function in PgJDBC for string quoting and escaping. That's partly because it might make it seem like a good idea.

There are built-in quoting functions quote_literal and quote_ident in PostgreSQL, but they are for PL/PgSQL functions that use EXECUTE. These days quote_literal is mostly obsoleted by EXECUTE ... USING, which is the parameterised version, because it's safer and easier. You cannot use them for the purpose you explain here, because they're server-side functions.

Imagine what happens if you get the value ');DROP SCHEMA public;-- from a malicious user. You'd produce:

insert into test values (1,'');DROP SCHEMA public;--');

which breaks down to two statements and a comment that gets ignored:

insert into test values (1,'');
DROP SCHEMA public;
--');

Whoops, there goes your database.

This response header can be used to configure a user-agent's built in reflective XSS protection. Currently, only Microsoft's Internet Explorer, Google Chrome and Safari (WebKit) support this header.

Internet Explorer 8 included a new feature to help prevent reflected cross-site scripting attacks, known as the XSS Filter. This filter runs by default in the Internet, Trusted, and Restricted security zones. Local Intranet zone pages may opt-in to the protection using the same header.

About the header that you posted in your question,

The header X-XSS-Protection: 1; mode=block enables the XSS Filter. Rather than sanitize the page, when a XSS attack is detected, the browser will prevent rendering of the page.

In March of 2010, we added to IE8 support for a new token in the X-XSS-Protection header, mode=block.

X-XSS-Protection: 1; mode=block

When this token is present, if a potential XSS Reflection attack is detected, Internet Explorer will prevent rendering of the page. Instead of attempting to sanitize the page to surgically remove the XSS attack, IE will render only “#”.

Internet Explorer recognizes a possible cross-site scripting attack. It logs the event and displays an appropriate message to the user. The MSDN article describes how this header works.

How this filter works in IE,

More on this article, https://blogs.msdn.microsoft.com/ie/2008/07/02/ie8-security-part-iv-the-xss-filter/

The XSS Filter operates as an IE8 component with visibility into all requests / responses flowing through the browser. When the filter discovers likely XSS in a cross-site request, it identifies and neuters the attack if it is replayed in the server’s response. Users are not presented with questions they are unable to answer – IE simply blocks the malicious script from executing.

With the new XSS Filter, IE8 Beta 2 users encountering a Type-1 XSS attack will see a notification like the following:

IE8 XSS Attack Notification

The page has been modified and the XSS attack is blocked.

In this case, the XSS Filter has identified a cross-site scripting attack in the URL. It has neutered this attack as the identified script was replayed back into the response page. In this way, the filter is effective without modifying an initial request to the server or blocking an entire response.

The Cross-Site Scripting Filter event is logged when Windows Internet Explorer 8 detects and mitigates a cross-site scripting (XSS) attack. Cross-site scripting attacks occur when one website, generally malicious, injects (adds) JavaScript code into otherwise legitimate requests to another website. The original request is generally innocent, such as a link to another page or a Common Gateway Interface (CGI) script providing a common service (such as a guestbook). The injected script generally attempts to access privileged information or services that the second website does not intend to allow. The response or the request generally reflects results back to the malicious website. The XSS Filter, a feature new to Internet Explorer 8, detects JavaScript in URL and HTTP POST requests. If JavaScript is detected, the XSS Filter searches evidence of reflection, information that would be returned to the attacking website if the attacking request were submitted unchanged. If reflection is detected, the XSS Filter sanitizes the original request so that the additional JavaScript cannot be executed. The XSS Filter then logs that action as a Cross-Site Script Filter event. The following image shows an example of a site that is modified to prevent a cross-site scripting attack.

Source: https://msdn.microsoft.com/en-us/library/dd565647(v=vs.85).aspx

Web developers may wish to disable the filter for their content. They can do so by setting an HTTP header:

X-XSS-Protection: 0

It is a good idea to create a dll class library that contain all common functionality. Each solution can reference this dll indepently regardless of other solutions.

Infact , this is how our sources are organized in my work (and I believe in many other places).

By the way , Solution can't explicitly depend on another solution.

1) Using the help function

Get into the python prompt and type the following command:

>>>help("modules")

This will list all the modules installed in the system. You don't need to install any additional packages to list them, but you need to manually search or filter the required module from the list.

2) Using pip freeze

sudo apt-get install python-pip
pip freeze

Even though you need to install additional packages to use this, this method allows you to easily search or filter the result with grep command. e.g. pip freeze | grep feed.

You can use whichever method is convenient for you.

• A leading slash tells the browser to start at the root directory.
• If you don't have the leading slash, you're referencing from the current directory.
• If you add two dots before the leading slash, it means you're referencing the parent of the current directory.

Take the following folder structure

notice:

• the ROOT checkmark is green,
• the second checkmark is orange,
• the third checkmark is purple,
• the forth checkmark is yellow

Now in the index.html.en file you'll want to put the following markup

<p>
    <span>src="check_mark.png"</span>
    <img src="check_mark.png" />
    <span>I'm purple because I'm referenced from this current directory</span>
</p>

<p>
    <span>src="/check_mark.png"</span>
    <img src="/check_mark.png" />
    <span>I'm green because I'm referenced from the ROOT directory</span>
</p>

<p>
    <span>src="subfolder/check_mark.png"</span>
    <img src="subfolder/check_mark.png" />
    <span>I'm yellow because I'm referenced from the child of this current directory</span>
</p>

<p>
    <span>src="/subfolder/check_mark.png"</span>
    <img src="/subfolder/check_mark.png" />
    <span>I'm orange because I'm referenced from the child of the ROOT directory</span>
</p>

<p>
    <span>src="../subfolder/check_mark.png"</span>
    <img src="../subfolder/check_mark.png" />
    <span>I'm purple because I'm referenced from the parent of this current directory</span>
</p>

<p>
    <span>src="subfolder/subfolder/check_mark.png"</span>
    <img src="subfolder/subfolder/check_mark.png" />
    <span>I'm [broken] because there is no subfolder two children down from this current directory</span>
</p>

<p>
    <span>src="/subfolder/subfolder/check_mark.png"</span>
    <img src="/subfolder/subfolder/check_mark.png" />
    <span>I'm purple because I'm referenced two children down from the ROOT directory</span>
</p>

Now if you load up the index.html.en file located in the second subfolder
http://example.com/subfolder/subfolder/

This will be your output

In English:

• ContentType: When sending data to the server, use this content type. Default is application/x-www-form-urlencoded; charset=UTF-8, which is fine for most cases.
• Accepts: The content type sent in the request header that tells the server what kind of response it will accept in return. Depends on DataType.
• DataType: The type of data that you're expecting back from the server. If none is specified, jQuery will try to infer it based on the MIME type of the response. Can be text, xml, html, script, json, jsonp.

As some sugested you can use apache or jax-ws. You can also use tools that generate code from WSDL such as ws-import but in my opinion the best way to consume web service is to create a dynamic client and invoke only operations you want not everything from wsdl. You can do this by creating a dynamic client: Sample code:

String endpointUrl = ...;

QName serviceName = new QName("http://com/ibm/was/wssample/echo/",
 "EchoService");
QName portName = new QName("http://com/ibm/was/wssample/echo/",
 "EchoServicePort");

/** Create a service and add at least one port to it. **/ 
Service service = Service.create(serviceName);
service.addPort(portName, SOAPBinding.SOAP11HTTP_BINDING, endpointUrl);

/** Create a Dispatch instance from a service.**/ 
Dispatch<SOAPMessage> dispatch = service.createDispatch(portName, 
SOAPMessage.class, Service.Mode.MESSAGE);

/** Create SOAPMessage request. **/
// compose a request message
MessageFactory mf = MessageFactory.newInstance(SOAPConstants.SOAP_1_1_PROTOCOL);

// Create a message.  This example works with the SOAPPART.
SOAPMessage request = mf.createMessage();
SOAPPart part = request.getSOAPPart();

// Obtain the SOAPEnvelope and header and body elements.
SOAPEnvelope env = part.getEnvelope();
SOAPHeader header = env.getHeader();
SOAPBody body = env.getBody();

// Construct the message payload.
SOAPElement operation = body.addChildElement("invoke", "ns1",
 "http://com/ibm/was/wssample/echo/");
SOAPElement value = operation.addChildElement("arg0");
value.addTextNode("ping");
request.saveChanges();

/** Invoke the service endpoint. **/
SOAPMessage response = dispatch.invoke(request);

/** Process the response. **/

If your config file is in a different path than classpath, you can add the configuration file path as a system property:

java -Dapp.config.path=path_to_config_file -jar your.jar

You could always do just:

a=[1,2,3]
b=['a','b']
c=[1,2,3,4]
d=[1,2,3]

a==b    #returns False
a==c    #returns False
a==d    #returns True

For Tomcat 7 to increase memory :

Identify your service name, you will find it in the service properties, under the "Path to executable" at the end of the line

There are multiple ways to check if a value exists in the database. Let me demonstrate how this can be done properly with PDO and mysqli.

PDO

PDO is the simpler option. To find out whether a value exists in the database you can use prepared statement and fetchColumn(). There is no need to fetch any data so we will only fetch 1 if the value exists.

<?php

// Connection code. 
$options = [
    \PDO::ATTR_ERRMODE            => \PDO::ERRMODE_EXCEPTION,
    \PDO::ATTR_EMULATE_PREPARES   => false,
];
$pdo = new \PDO('mysql:host=localhost;port=3306;dbname=test;charset=utf8mb4', 'testuser', 'password', $options);

// Prepared statement
$stmt = $pdo->prepare('SELECT 1 FROM tblUser WHERE email=?');
$stmt->execute([$_POST['email']]);
$exists = $stmt->fetchColumn(); // either 1 or null

if ($exists) {
    echo 'Email exists in the database.';
} else {
    // email doesn't exist yet
}

For more examples see: How to check if email exists in the database?

MySQLi

As always mysqli is a little more cumbersome and more restricted, but we can follow a similar approach with prepared statement.

<?php

// Connection code
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = new \mysqli('localhost', 'testuser', 'password', 'test');
$mysqli->set_charset('utf8mb4');

// Prepared statement
$stmt = $mysqli->prepare('SELECT 1 FROM tblUser WHERE email=?');
$stmt->bind_param('s', $_POST['email']);
$stmt->execute();
$exists = (bool) $stmt->get_result()->fetch_row(); // Get the first row from result and cast to boolean

if ($exists) {
    echo 'Email exists in the database.';
} else {
    // email doesn't exist yet
}

Instead of casting the result row(which might not even exist) to boolean, you can also fetch COUNT(1) and read the first item from the first row using fetch_row()[0]

For more examples see: How to check whether a value exists in a database using mysqli prepared statements

Minor remarks

• If someone suggests you to use mysqli_num_rows(), don't listen to them. This is a very bad approach and could lead to performance issues if misused.
• Don't use real_escape_string(). This is not meant to be used as a protection against SQL injection. If you use prepared statements correctly you don't need to worry about any escaping.
• If you want to check if a row exists in the database before you try to insert a new one, then it is better not to use this approach. It is better to create a unique key in the database and let it throw an exception if a duplicate value exists.

Do this:

<ToggleButton 
        android:id="@+id/toggle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/check"   <!--check.xml-->
        android:layout_margin="10dp"
        android:textOn=""
        android:textOff=""
        android:focusable="false"
        android:focusableInTouchMode="false"
        android:layout_centerVertical="true"/>

create check.xml in drawable folder

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- When selected, use grey -->
    <item android:drawable="@drawable/selected_image"
          android:state_checked="true" />
    <!-- When not selected, use white-->
    <item android:drawable="@drawable/unselected_image"
        android:state_checked="false"/>

 </selector>

Simple and clean way to print a 2D array.

System.out.println(Arrays.deepToString(array).replace("], ", "]\n").replace("[[", "[").replace("]]", "]"));

for complette URL with protocol, servername and parameters:

 $base_url = ( isset($_SERVER['HTTPS']) && $_SERVER['HTTPS']=='on' ? 'https' : 'http' ) . '://' .  $_SERVER['HTTP_HOST'];
 $url = $base_url . $_SERVER["REQUEST_URI"];

Swift 4 extension with border width and color. Works great!

@IBDesignable
final class SideBorders: UIView {
@IBInspectable var topColor: UIColor = UIColor.clear
@IBInspectable var topWidth: CGFloat = 0

@IBInspectable var rightColor: UIColor = UIColor.clear
@IBInspectable var rightWidth: CGFloat = 0

@IBInspectable var bottomColor: UIColor = UIColor.clear
@IBInspectable var bottomWidth: CGFloat = 0

@IBInspectable var leftColor: UIColor = UIColor.clear
@IBInspectable var leftWidth: CGFloat = 0

override func draw(_ rect: CGRect) {
    let topBorder = CALayer()
    topBorder.backgroundColor = topColor.cgColor
    topBorder.frame = CGRect(x: 0, y: 0, width: self.frame.size.width, height: topWidth)
    self.layer.addSublayer(topBorder)

    let rightBorder = CALayer()
    rightBorder.backgroundColor = rightColor.cgColor
    rightBorder.frame = CGRect(x: self.frame.size.width - rightWidth, y: 0, width: rightWidth, height: self.frame.size.height)
    self.layer.addSublayer(rightBorder)

    let bottomBorder = CALayer()
    bottomBorder.backgroundColor = bottomColor.cgColor
    bottomBorder.frame = CGRect(x: 0, y: self.frame.size.height - bottomWidth, width: self.frame.size.width, height: bottomWidth)
    self.layer.addSublayer(bottomBorder)

    let leftBorder = CALayer()
    leftBorder.backgroundColor = leftColor.cgColor
    leftBorder.frame = CGRect(x: 0, y: self.frame.size.height - leftWidth, width: self.frame.size.width, height: leftWidth)
    self.layer.addSublayer(leftBorder)
}

}

I have IsDBNull in a program which reads a lot of data from a database. With IsDBNull it loads data in about 20 seconds. Without IsDBNull, about 1 second.

So I think it is better to use:

public String TryGetString(SqlDataReader sqlReader, int row)
{
    String res = "";
    try
    {
        res = sqlReader.GetString(row);
    }
    catch (Exception)
    { 
    }
    return res;
}

This is happen when you try to push initially.Because in your GitHub repo have readMe.md or any other new thing which is not in your local repo. First you have to merge unrelated history of your github repo.To do that

git pull origin master --allow-unrelated-histories

then you can get the other files from repo(readMe.md or any)using this

git pull origin master

After that

git push -u origin master

Now you successfully push your all the changes into Github repo.I'm not expert in git but every time these step work for me.

the answer with the host name didn't work for me but this did :

git clone file:////home/git/repositories/MyProject.git/

I had the same problem in some browser to access to my SSL site. I have found that I had to give to fireFox the right proxy (FireFox was accessing directly to internet).

Depending of the lan configuration (Tunneling, filtering, proxy redirection), the "direct access to internet" mode for FireFox throws this error.

I needed to run this command

sudo lsof -i :80 # checks port 8080

Then i got

Just want to open the app through browser? You can achieve it using below code:

HTML:

<a href="intent:#Intent;action=packageName;category=android.intent.category.DEFAULT;category=android.intent.category.BROWSABLE;end">Click here</a>

Manifest:

<intent-filter>
      <action android:name="packageName" />
      <category android:name="android.intent.category.DEFAULT" />
      <category android:name="android.intent.category.BROWSABLE" />
</intent-filter>

This intent filter should be in Launcher Activity.

If you want to pass the data on click of browser link, just refer this link.

In simple words, there are two things:

Hive can manage things in warehouse i.e. it will not delete data out of warehouse. When we delete table:

1) For internal tables the data is managed internally in warehouse. So will be deleted.

2) For external tables the data is managed eternal from warehouse. So can't be deleted and clients other then hive can also use it.

Title bar in android is called Action bar. So if you want to remove it from any specific activity, go to AndroidManifest.xml and add the theme type. Such as android:theme="@style/Theme.AppCompat.Light.NoActionBar".

Example:

<activity
    android:name=".SplashActivity"
    android:noHistory="true"
    android:theme="@style/Theme.AppCompat.Light.NoActionBar">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

Javascript which runs on the client machine can't access the local disk file system due to security restrictions.

If you want to access the client's disk file system then look into an embedded client application which you serve up from your webpage, like an Applet, Silverlight or something like that. If you like to access the server's disk file system, then look for the solution in the server side corner using a server side programming language like Java, PHP, etc, whatever your webserver is currently using/supporting.

A lot of other answers are focusing on a pattern that does work, but their explanations aren't really very thorough as to why your current code doesn't work.

Your code, for reference:

function funcName() {
    alert("test");
}

var func = funcName();
var run = setInterval("func",10000)

Let's break this up into chunks. Your function funcName is fine. Note that when you call funcName (in other words, you run it) you will be alerting "test". But notice that funcName() -- the parentheses mean to "call" or "run" the function -- doesn't actually return a value. When a function doesn't have a return value, it defaults to a value known as undefined.

When you call a function, you append its argument list to the end in parentheses. When you don't have any arguments to pass the function, you just add empty parentheses, like funcName(). But when you want to refer to the function itself, and not call it, you don't need the parentheses because the parentheses indicate to run it.

So, when you say:

var func = funcName();

You are actually declaring a variable func that has a value of funcName(). But notice the parentheses. funcName() is actually the return value of funcName. As I said above, since funcName doesn't actually return any value, it defaults to undefined. So, in other words, your variable func actually will have the value undefined.

Then you have this line:

var run = setInterval("func",10000)

The function setInterval takes two arguments. The first is the function to be ran every so often, and the second is the number of milliseconds between each time the function is ran.

However, the first argument really should be a function, not a string. If it is a string, then the JavaScript engine will use eval on that string instead. So, in other words, your setInterval is running the following JavaScript code:

func
// 10 seconds later....
func
// and so on

However, func is just a variable (with the value undefined, but that's sort of irrelevant). So every ten seconds, the JS engine evaluates the variable func and returns undefined. But this doesn't really do anything. I mean, it technically is being evaluated every 10 seconds, but you're not going to see any effects from that.

The solution is to give setInterval a function to run instead of a string. So, in this case:

var run = setInterval(funcName, 10000);

Notice that I didn't give it func. This is because func is not a function in your code; it's the value undefined, because you assigned it funcName(). Like I said above, funcName() will call the function funcName and return the return value of the function. Since funcName doesn't return anything, this defaults to undefined. I know I've said that several times now, but it really is a very important concept: when you see funcName(), you should think "the return value of funcName". When you want to refer to a function itself, like a separate entity, you should leave off the parentheses so you don't call it: funcName.

So, another solution for your code would be:

var func = funcName;
var run = setInterval(func, 10000);

However, that's a bit redundant: why use func instead of funcName?

Or you can stay as true as possible to the original code by modifying two bits:

var func = funcName;
var run = setInterval("func()", 10000);

In this case, the JS engine will evaluate func() every ten seconds. In other words, it will alert "test" every ten seconds. However, as the famous phrase goes, eval is evil, so you should try to avoid it whenever possible.

Another twist on this code is to use an anonymous function. In other words, a function that doesn't have a name -- you just drop it in the code because you don't care what it's called.

setInterval(function () {
    alert("test");
}, 10000);

In this case, since I don't care what the function is called, I just leave a generic, unnamed (anonymous) function there.

I have this piece of code i hope it may help u.

ASP.NET MVC offers us three options ViewData, ViewBag, and TempData for passing data from controller to view and in next request. ViewData and ViewBag are almost similar and TempData performs additional responsibility. Lets discuss or get key points on those three objects:

Similarities between ViewBag & ViewData :

• Helps to maintain data when you move from controller to view.
• Used to pass data from controller to corresponding view.
• Short life means value becomes null when redirection occurs. This is because their goal is to provide a way to communicate between controllers and views. It’s a communication mechanism within the server call.

Difference between ViewBag & ViewData:

• ViewData is a dictionary of objects that is derived from ViewDataDictionary class and accessible using strings as keys.
• ViewBag is a dynamic property that takes advantage of the new dynamic features in C# 4.0.
• ViewData requires typecasting for complex data type and check for null values to avoid error.
• ViewBag doesn’t require typecasting for complex data type.

ViewBag & ViewData Example:

public ActionResult Index()
{
    ViewBag.Name = "Monjurul Habib";
    return View();
}


public ActionResult Index()
{
    ViewData["Name"] = "Monjurul Habib";
    return View();
} 

In View:

@ViewBag.Name 
@ViewData["Name"] 

TempData:

TempData is also a dictionary derived from TempDataDictionary class and stored in short lives session and it is a string key and object value. The difference is that the life cycle of the object. TempData keep the information for the time of an HTTP Request. This mean only from one page to another. This also work with a 302/303 redirection because it’s in the same HTTP Request. Helps to maintain data when you move from one controller to other controller or from one action to other action. In other words when you redirect, “TempData” helps to maintain data between those redirects. It internally uses session variables. Temp data use during the current and subsequent request only means it is use when you are sure that next request will be redirecting to next view. It requires typecasting for complex data type and check for null values to avoid error. Generally used to store only one time messages like error messages, validation messages.

public ActionResult Index()
{
  var model = new Review()
            {
                Body = "Start",
                Rating=5
            };
    TempData["ModelName"] = model;
    return RedirectToAction("About");
}

public ActionResult About()
{
    var model= TempData["ModelName"];
    return View(model);
}

The last mechanism is the Session which work like the ViewData, like a Dictionary that take a string for key and object for value. This one is stored into the client Cookie and can be used for a much more long time. It also need more verification to never have any confidential information. Regarding ViewData or ViewBag you should use it intelligently for application performance. Because each action goes through the whole life cycle of regular asp.net mvc request. You can use ViewData/ViewBag in your child action but be careful that you are not using it to populate the unrelated data which can pollute your controller.

You need to double escape any RegExp characters (once for the slash in the string and once for the regexp):

  "$TESTONE $TESTONE".replace( new RegExp("\\$TESTONE","gm"),"foo")

Otherwise, it looks for the end of the line and 'TESTONE' (which it never finds).

Personally, I'm not a big fan of building regexp's using strings for this reason. The level of escaping that's needed could lead you to drink. I'm sure others feel differently though and like drinking when writing regexes.

You'll want to use the clone() method in order to get a deep copy of the element:

$(function(){
  var $button = $('.button').clone();
  $('.package').html($button);
});

Full demo: http://jsfiddle.net/3rXjx/

From the jQuery docs:

The .clone() method performs a deep copy of the set of matched elements, meaning that it copies the matched elements as well as all of their descendant elements and text nodes. When used in conjunction with one of the insertion methods, .clone() is a convenient way to duplicate elements on a page.

Consider:

Function GetFolder() As String
    Dim fldr As FileDialog
    Dim sItem As String
    Set fldr = Application.FileDialog(msoFileDialogFolderPicker)
    With fldr
        .Title = "Select a Folder"
        .AllowMultiSelect = False
        .InitialFileName = Application.DefaultFilePath
        If .Show <> -1 Then GoTo NextCode
        sItem = .SelectedItems(1)
    End With
NextCode:
    GetFolder = sItem
    Set fldr = Nothing
End Function

If you want all the bars to get the same color (fill), you can easily add it inside geom_bar.

ggplot(data=df, aes(x=c1+c2/2, y=c3)) + 
geom_bar(stat="identity", width=c2, fill = "#FF6666")

Add fill = the_name_of_your_var inside aes to change the colors depending of the variable :

c4 = c("A", "B", "C")
df = cbind(df, c4)
ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) + 
geom_bar(stat="identity", width=c2)

Use scale_fill_manual() if you want to manually the change of colors.

ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) + 
geom_bar(stat="identity", width=c2) + 
scale_fill_manual("legend", values = c("A" = "black", "B" = "orange", "C" = "blue"))

All answers posted so far are giving the right solutions, however no one answer was able to properly explain the underlying cause of the concrete problem.

Facelets is a XML based view technology which uses XHTML+XML to generate HTML output. XML has five special characters which has special treatment by the XML parser:

• < the start of a tag.
• > the end of a tag.
• " the start and end of an attribute value.
• ' the alternative start and end of an attribute value.
• & the start of an entity (which ends with ;).

In case of & which is not followed by # (e.g.  ,  , etc), the XML parser is implicitly looking for one of the five predefined entity names lt, gt, amp, quot and apos, or any manually defined entity name. However, in your particular case, you was using & as a JavaScript operator, not as an XML entity. This totally explains the XML parsing error you got:

The entity name must immediately follow the '&' in the entity reference

In essence, you're writing JavaScript code in the wrong place, a XML document instead of a JS file, so you should be escaping all XML special characters accordingly. The & must be escaped as &.

So, in your particular case, the

if (Modernizr.canvas && Modernizr.localstorage && 

must become

if (Modernizr.canvas && Modernizr.localstorage &&

to make it XML-valid.

However, this makes the JavaScript code harder to read and maintain. As stated in Mozilla Developer Network's excellent document Writing JavaScript for XHTML, you should be placing the JavaScript code in a character data (CDATA) block. Thus, in JSF terms, that would be:

<h:outputScript>
    <![CDATA[
        // ...
    ]]>
</h:outputScript>

The XML parser will interpret the block's contents as "plain vanilla" character data and not as XML and hence interpret the XML special characters "as-is".

But, much better is to just put the JS code in its own JS file which you include by <script src>, or in JSF terms, the <h:outputScript>.

<h:outputScript name="onload.js" target="body" />

(note the target="body"; this way JSF will automatically render the <script> at the very end of <body>, regardless of where <h:outputScript> itself is located, hereby achieving the same effect as with window.onload and $(document).ready(); so you don't need to use those anymore in that script)

This way you don't need to worry about XML-special characters in your JS code. As an additional bonus, this gives you the opportunity to let the browser cache the JS file so that total response size is smaller.

If error reason is extension use incognito Ctrl+Shift+N. In incognito mode Chrome does not have extensions.

UPD. If you need some extension in incognito mode e.g. ReduxDevTools or any other, in extension settings turn on "Allow in incognito"

In the same spirit as https://stackoverflow.com/a/6943976/7154924:

cat -A

-A, --show-all
       equivalent to -vET
-v, --show-nonprinting
       use ^ and M- notation, except for LFD and TAB
-E, --show-ends
       display $ at end of each line
-T, --show-tabs
       display TAB characters as ^I

Alternatively, or at the same time, you can pipe to tr to substitute arbitrary characters to the desired ones for display, before piping to a pager like less if desired.

Just use this code :

Using getifaddrs you can get MAC address from the family AF_PACKET.

In order to display the MAC address to each interface, you can proceed like this:

#include <stdio.h>
#include <ifaddrs.h>
#include <netpacket/packet.h>

int main (int argc, const char * argv[])
{
    struct ifaddrs *ifaddr=NULL;
    struct ifaddrs *ifa = NULL;
    int i = 0;

    if (getifaddrs(&ifaddr) == -1)
    {
         perror("getifaddrs");
    }
    else
    {
         for ( ifa = ifaddr; ifa != NULL; ifa = ifa->ifa_next)
         {
             if ( (ifa->ifa_addr) && (ifa->ifa_addr->sa_family == AF_PACKET) )
             {
                  struct sockaddr_ll *s = (struct sockaddr_ll*)ifa->ifa_addr;
                  printf("%-8s ", ifa->ifa_name);
                  for (i=0; i <s->sll_halen; i++)
                  {
                      printf("%02x%c", (s->sll_addr[i]), (i+1!=s->sll_halen)?':':'\n');
                  }
             }
         }
         freeifaddrs(ifaddr);
    }
    return 0;
}

You can not ask for instance during configuration phase - you can ask only for providers.

var app = angular.module('modx', []);

// configure stuff
app.config(function($routeProvider, $locationProvider) {
  // you can inject any provider here
});

// run blocks
app.run(function($rootScope) {
  // you can inject any instance here
});

See http://docs.angularjs.org/guide/module for more info.

If you're willing to include the jQuery UI library, in addition to jQuery itself, then you can simply use hide(), with additional arguments, as follows:

$(document).ready(
    function(){
        $('#slider').click(
            function(){
                $(this).hide('slide',{direction:'right'},1000);

            });
    });

JS Fiddle demo.

Without using jQuery UI, you could achieve your aim just using animate():

$(document).ready(
    function(){
        $('#slider').click(
            function(){
                $(this)
                    .animate(
                        {
                            'margin-left':'1000px'
                            // to move it towards the right and, probably, off-screen.
                        },1000,
                        function(){
                            $(this).slideUp('fast');
                            // once it's finished moving to the right, just 
                            // removes the the element from the display, you could use
                            // `remove()` instead, or whatever.
                        }
                        );

            });

If you do choose to use jQuery UI, then I'd recommend linking to the Google-hosted code, at: https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.6/jquery-ui.min.js

I tried using the code that @Vinayak B submitted. However I'm getting an error saying: No provider for smtp

I created a new question for this with more information HERE

I was able to fix it myself after all. I had to use an other mail.jar and I had to make sure my "access for less secure apps" was turned on.

I hope this helps anyone who has the same problem. With this done, this piece of code works on the google glass too.

As khaos said, a destination unreachable could also mean that something is blocking the way from or to your destination. For example an ACL that filters bad IP addresses.

The lock accessed is on the object, not on the method. Which variables are accessed within the method is irrelevant.

Adding "synchronized" to the method means the thread running the code must acquire the lock on the object before proceeding. Adding "static synchronized" means the thread running the code must acquire the lock on the class object before proceeding. Alternatively you can wrap code in a block like this:

public void addA() {
    synchronized(this) {
        a++;
    }
}

so that you can specify the object whose lock must be acquired.

If you want to avoid locking on the containing object you can choose between:

• using synchronized blocks that specify different locks
• making a and b atomic (using java.util.concurrent.atomic)

$ python3
>>> from itertools import repeat
>>> list(repeat(0, 7))
[0, 0, 0, 0, 0, 0, 0]

Git is supposed to understand what files already exist on the server, unless you somehow made a huge difference to your tree and the new changes need to be sent.

To create a new branch with a copy of your current state

git checkout -b new_branch #< create a new local branch with a copy of your code
git push origin new_branch #< pushes to the server

Can you please describe the steps you did to understand what might have made your repository need to send that much to the server.

Both Redirect::to() and Redirect::away() should work.

Difference

Redirect::to() does additional URL checks and generations. Those additional steps are done in Illuminate\Routing\UrlGenerator and do the following, if the passed URL is not a fully valid URL (even with protocol):

Determines if URL is secure
rawurlencode() the URL
trim() URL

How to make a self extracting archive that runs your setup.exe with 7zip -sfx switch

Here are the steps.

Step 1 - Setup your installation folder

To make this easy create a folder c:\Install. This is where we will copy all the required files.

Step 2 - 7Zip your installers

1. Go to the folder that has your .msi and your setup.exe
2. Select both the .msi and the setup.exe
3. Right-Click and choose 7Zip --> "Add to Archive"
4. Name your archive "Installer.7z" (or a name of your choice)
5. Click Ok
6. You should now have "Installer.7z".
7. Copy this .7z file to your c:\Install directory

Step 3 - Get the 7z-Extra sfx extension module

You need to download 7zSD.sfx

1. Download one of the LZMA packages from here
2. Extract the package and find 7zSD.sfx in the bin folder.
3. Copy the file "7zSD.sfx" to c:\Install

Step 4 - Setup your config.txt

I would recommend using NotePad++ to edit this text file as you will need to encode in UTF-8, the following instructions are using notepad++.

1. Using windows explorer go to c:\Install
2. right-click and choose "New Text File" and name it config.txt
3. right-click and choose "Edit with NotePad++
4. Click the "Encoding Menu" and choose "Encode in UTF-8"

5. Enter something like this:

   ;!@Install@!UTF-8!
   Title="SOFTWARE v1.0.0.0"
   BeginPrompt="Do you want to install SOFTWARE v1.0.0.0?"
   RunProgram="setup.exe"
   ;!@InstallEnd@!
   

Edit this replacing [SOFTWARE v1.0.0.0] with your product name. Notes on the parameters and options for the setup file are here.

CheckPoint

You should now have a folder "c:\Install" with the following 3 files:

1. Installer.7z
2. 7zSD.sfx
3. config.txt

Step 5 - Create the archive

These instructions I found on the web but nowhere did it explain any of the 4 steps above.

1. Open a cmd window, Window + R --> cmd --> press enter

2. In the command window type the following

   cd \
   cd Install
   copy /b 7zSD.sfx + config.txt + Installer.7z MyInstaller.exe
   

3. Look in c:\Install and you will now see you have a MyInstaller.exe

You are finished

Run the installer

Double click on MyInstaller.exe and it will prompt with your message. Click OK and the setup.exe will run.

P.S. Note on Automation

Now that you have this working in your c:\Install directory I would create an "Install.bat" file and put the copy script in it.

copy /b 7zSD.sfx + config.txt + Installer.7z MyInstaller.exe

Now you can just edit and run the Install.bat every time you need to rebuild a new version of you deployment package.

You can set the default search_path at the database level:

ALTER DATABASE <database_name> SET search_path TO schema1,schema2;

Or at the user or role level:

ALTER ROLE <role_name> SET search_path TO schema1,schema2;

Or if you have a common default schema in all your databases you could set the system-wide default in the config file with the search_path option.

When a database is created it is created by default from a hidden "template" database named template1, you could alter that database to specify a new default search path for all databases created in the future. You could also create another template database and use CREATE DATABASE <database_name> TEMPLATE <template_name> to create your databases.

While some of the answers are technically correct, they are not advisable.

• The java.util.Date & Calendar classes are notoriously troublesome. Because of flaws in design and implementation, avoid them. Fortunately we have our choice of two other excellent date-time libraries:
  • Joda-Time
    This popular open-source free-of-cost library can be used across several versions of Java. Many examples of its usage may be found on StackOverflow. Reading some of these will help get you up to speed quickly.
  • java.time.* package
    This new set of classes are inspired by Joda-Time and defined by JSR 310. These classes are built into Java 8. A project is underway to backport these classes to Java 7, but that backporting is not backed by Oracle.
• As Kristopher Johnson correctly noted in his comment on the question, the other answers ignore vital issues of:
  • Time of Day
    Date has both a date portion and a time-of-day portion)
  • Time Zone
    The beginning of a day depends on the time zone. If you fail to specify a time zone, the JVM's default time zone is applied. That means the behavior of your code may change when run on other computers or with a modified time zone setting. Probably not what you want.
  • Locale
    The Locale's language specifies how to interpret the words (name of month and of day) encountered during parsing. (The answer by BalusC handles this properly.) Also, the Locale affects the output of some formatters when generating a string representation of your date-time.

Joda-Time

A few notes about Joda-Time follow.

Time Zone

In Joda-Time, a DateTime object truly knows its own assigned time zone. This contrasts the java.util.Date class which seems to have a time zone but does not.

Note in the example code below how we pass a time zone object to the formatter which parses the string. That time zone is used to interpret that date-time as having occurred in that time zone. So you need to think about and determine the time zone represented by that string input.

Since you have no time portion in your input string, Joda-Time assigns the first moment of the day of the specified time zone as the time-of-day. Usually this means 00:00:00 but not always, because of Daylight Saving Time (DST) or other anomalies. By the way, you can do the same to any DateTime instance by calling withTimeAtStartOfDay.

Formatter Pattern

The characters used in a formatter's pattern are similar in Joda-Time to those in java.util.Date/Calendar but not exactly the same. Carefully read the doc.

Immutability

We usually use the immutable classes in Joda-Time. Rather than modify an existing Date-Time object, we call methods that create a new fresh instance based on the other object with most aspects copied except where alterations were desired. An example is the call to withZone in last line below. Immutability helps to make Joda-Time very thread-safe, and can also make some work more clear.

Conversion

You will need java.util.Date objects for use with other classes/framework that do not know about Joda-Time objects. Fortunately, it is very easy to move back and forth.

Going from a java.util.Date object (here named date) to Joda-Time DateTime…

org.joda.time.DateTime dateTime = new DateTime( date, timeZone );

Going the other direction from Joda-Time to a java.util.Date object…

java.util.Date date = dateTime.toDate();

Sample Code

String input = "January 2, 2010";

java.util.Locale locale = java.util.Locale.US;
DateTimeZone timeZone = DateTimeZone.forID( "Pacific/Honolulu" ); // Arbitrarily chosen for example.
DateTimeFormatter formatter = DateTimeFormat.forPattern( "MMMM d, yyyy" ).withZone( timeZone ).withLocale( locale );
DateTime dateTime = formatter.parseDateTime( input );

System.out.println( "dateTime: " + dateTime );
System.out.println( "dateTime in UTC/GMT: " + dateTime.withZone( DateTimeZone.UTC ) );

When run…

dateTime: 2010-01-02T00:00:00.000-10:00
dateTime in UTC/GMT: 2010-01-02T10:00:00.000Z

1. Download & mount http://adcdownload.apple.com/Developer_Tools/Xcode_7.3.1/Xcode_7.3.1.dmg I was first wandered if it could be mounted directly through hdiutil attach and looks like it could but not for everyone's accounts.

2. Open to see its content and copy Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/7.1 to same path into Xcode application directory.

3. Restart Xcode

If you want/need to do it without int:

sum(int(c) * (2 ** i) for i, c in enumerate(s[::-1]))

This reverses the string (s[::-1]), gets each character c and its index i (for i, c in enumerate(), multiplies the integer of the character (int(c)) by two to the power of the index (2 ** i) then adds them all together (sum()).

What about thinking the following way:

• A relationship between a class and an abstract class is of type "is-a"
• A relationship between a class and an interface is of type "has-a"

So when you have an abstract class Mammals, a subclass Human, and an interface Driving, then you can say

• each Human is-a Mammal
• each Human has-a Driving (behavior)

My suggestion is that the book knowledge phrase indicates that he wanted to hear the semantic difference between both (like others here already suggested).

Array is faster - all memory is pre-allocated in advance.

Another possible solution I came up with was:

re.sub(r'([uU]+(.)?\s)',' you ', text)

You should not include commands.c in your header file. In general, you should not include .c files. Rather, commands.c should include commands.h. As defined here, the C preprocessor is inserting the contents of commands.c into commands.h where the include is. You end up with two definitions of f123 in commands.h.

commands.h

#ifndef COMMANDS_H_
#define COMMANDS_H_

void f123();

#endif

commands.c

#include "commands.h"

void f123()
{
    /* code */
}

There are two things to remember here. One is to add the -PassThru argument and two is to add the -Wait argument. You need to add the wait argument because of this defect: http://connect.microsoft.com/PowerShell/feedback/details/520554/start-process-does-not-return-exitcode-property

-PassThru [<SwitchParameter>]
    Returns a process object for each process that the cmdlet started. By d
    efault, this cmdlet does not generate any output.

Once you do this a process object is passed back and you can look at the ExitCode property of that object. Here is an example:

$process = start-process ping.exe -windowstyle Hidden -ArgumentList "-n 1 -w 127.0.0.1" -PassThru -Wait
$process.ExitCode

# This will print 1

If you run it without -PassThru or -Wait, it will print out nothing.

I've been looking at this problem for the better part of a day, and here's what I've come up with (credit to https://stackoverflow.com/a/5249214/196358 for pointing me in this direction).

(Note: I'm using flask-sqlalchemy, so my model declaration format is a bit different from straight sqlalchemy).

In my models.py file:

import json

class Serializer(object):
  __public__ = None
  "Must be implemented by implementors"

  def to_serializable_dict(self):
    dict = {}
    for public_key in self.__public__:
      value = getattr(self, public_key)
      if value:
        dict[public_key] = value
    return dict

class SWEncoder(json.JSONEncoder):
  def default(self, obj):
    if isinstance(obj, Serializer):
      return obj.to_serializable_dict()
    if isinstance(obj, (datetime)):
      return obj.isoformat()
    return json.JSONEncoder.default(self, obj)


def SWJsonify(*args, **kwargs):
  return current_app.response_class(json.dumps(dict(*args, **kwargs), cls=SWEncoder, indent=None if request.is_xhr else 2), mimetype='application/json')
  # stolen from https://github.com/mitsuhiko/flask/blob/master/flask/helpers.py

and all my model objects look like this:

class User(db.Model, Serializer):
  __public__ = ['id','username']
  ... field definitions ...

In my views I call SWJsonify wherever I would have called Jsonify, like so:

@app.route('/posts')
def posts():
  posts = Post.query.limit(PER_PAGE).all()
  return SWJsonify({'posts':posts })

Seems to work pretty well. Even on relationships. I haven't gotten far with it, so YMMV, but so far it feels pretty "right" to me.

Suggestions welcome.

You just need to escape characters that have special meaning: # $ % & ~ _ ^ \ { }

Here in your code demo is id where you want to display your result after click event has occur and just nothing.

You can take anything

<p id="demo">

or

<div id="demo"> 

It is just node in a document where you just want to display your result.

Fixed it by setting the class name to the property "classesToBeBound" of the JAXB marshaller:

<bean id="jaxbMarshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
        <property name="classesToBeBound">
          <list>
                <value>myclass</value>
          </list>
        </property>
</bean>

A simple question should be followed by a short, simple and clear answer.

• When we are getting a value of the property it fires its get{} part.

• When we are setting a value to the property it fires its set{} part.

PS. When setting a value to the property, SWIFT automatically creates a constant named "newValue" = a value we are setting. After a constant "newValue" becomes accessible in the property's set{} part.

Example:

var A:Int = 0
var B:Int = 0

var C:Int {
get {return 1}
set {print("Recived new value", newValue, " and stored into 'B' ")
     B = newValue
     }
}

//When we are getting a value of C it fires get{} part of C property
A = C 
A            //Now A = 1

//When we are setting a value to C it fires set{} part of C property
C = 2
B            //Now B = 2

~dp0 : d=drive, p=path, %0=full path\name of this batch-file.

cd /d %~dp0 will change the path to the same, where the batch file resides.

It's rather very simple. Consider the following Array object.

var names: [String] = ["jack", "rose", "jill"]

In order to obtain the index of the element rose, all you have to do is:

names.index(of: "rose") // returns 1

Note:

• Array.index(of:) returns an Optional<Int>.

• nil implies that the element isn't present in the array.

• You might want to force-unwrap the returned value or use an if-let to get around the optional.

tr.border{

Use "git reset HEAD <file>..." to unstage fils

ex : to unstage all files

git reset HEAD .

to unstage one file

git reset HEAD nameFile.txt

put you $image in img tag of html

try this

echo '<img src="your_path_to_image/'.$image.'" />';

instead of

print $image;

your_path_to_image would be absolute path of your image folder like eg: /home/son/public_html/images/ or as your folder structure on server.

Update 2 :

if your image is resides in the same folder where this page file is exists
you can user this

echo '<img src="'.$image.'" />';

Try this:

var jIsHasKids = $('#chkIsHasKids').attr('checked');
jIsHasKids = jIsHasKids.toString().toLowerCase();
//OR
jIsHasKids = jIsHasKids.val().toLowerCase();

Giving flex a value solved the problem for me, e.g.

There are many ways to remove a key from a hash and get the remaining hash in Ruby.

1. .slice => It will return selected keys and not delete them from the original hash. Use slice! if you want to remove the keys permanently else use simple slice.

   2.2.2 :074 > hash = {"one"=>1, "two"=>2, "three"=>3}
    => {"one"=>1, "two"=>2, "three"=>3} 
   2.2.2 :075 > hash.slice("one","two")
    => {"one"=>1, "two"=>2} 
   2.2.2 :076 > hash
    => {"one"=>1, "two"=>2, "three"=>3} 
   

2. .delete => It will delete the selected keys from the original hash(it can accept only one key and not more than one).

   2.2.2 :094 > hash = {"one"=>1, "two"=>2, "three"=>3}
    => {"one"=>1, "two"=>2, "three"=>3} 
   2.2.2 :095 > hash.delete("one")
    => 1 
   2.2.2 :096 > hash
    => {"two"=>2, "three"=>3} 
   

3. .except => It will return the remaining keys but not delete anything from the original hash. Use except! if you want to remove the keys permanently else use simple except.

   2.2.2 :097 > hash = {"one"=>1, "two"=>2, "three"=>3}
    => {"one"=>1, "two"=>2, "three"=>3} 
   2.2.2 :098 > hash.except("one","two")
    => {"three"=>3} 
   2.2.2 :099 > hash
    => {"one"=>1, "two"=>2, "three"=>3}         
   

4. .delete_if => In case you need to remove a key based on a value. It will obviously remove the matching keys from the original hash.

   2.2.2 :115 > hash = {"one"=>1, "two"=>2, "three"=>3, "one_again"=>1}
    => {"one"=>1, "two"=>2, "three"=>3, "one_again"=>1} 
   2.2.2 :116 > value = 1
    => 1 
   2.2.2 :117 > hash.delete_if { |k,v| v == value }
    => {"two"=>2, "three"=>3} 
   2.2.2 :118 > hash
    => {"two"=>2, "three"=>3} 
   

5. .compact => It is used to remove all nil values from the hash. Use compact! if you want to remove the nil values permanently else use simple compact.

   2.2.2 :119 > hash = {"one"=>1, "two"=>2, "three"=>3, "nothing"=>nil, "no_value"=>nil}
    => {"one"=>1, "two"=>2, "three"=>3, "nothing"=>nil, "no_value"=>nil} 
   2.2.2 :120 > hash.compact
    => {"one"=>1, "two"=>2, "three"=>3}

Use empty() and/or is_null()

http://www.php.net/empty http://www.php.net/is_null

Empty alone will achieve your current usage, is_null would just make more control possible if you wanted to distinguish between a field that is null and a field that is empty.

• [ is the same as the test builtin, and works like the test binary (man test)
  • works about the same as [ in all the other sh-based shells in many UNIX-like environments
  • only supports a single condition. Multiple tests with the bash && and || operators must be in separate brackets.
  • doesn't natively support a 'not' operator. To invert a condition, use a ! outside the first bracket to use the shell's facility for inverting command return values.
  • == and != are literal string comparisons
• [[ is a bash
  • is bash-specific, though others shells may have implemented similar constructs. Don't expect it in an old-school UNIX sh.
  • == and != apply bash pattern matching rules, see "Pattern Matching" in man bash
  • has a =~ regex match operator
  • allows use of parentheses and the !, &&, and || logical operators within the brackets to combine subexpressions

Aside from that, they're pretty similar -- most individual tests work identically between them, things only get interesting when you need to combine different tests with logical AND/OR/NOT operations.

If you just don't want to waste your time on cross-domain issues during development and testing of your app you can use addon Force CORS for FF.

UPDATE: It seems that this addon no longer exists. But there is another option - this Chrome extension

i know this is an old post but there is an option to sent the elemd id with the function call:

<button id='expand' class='btn expand' onclick='f1(this)'>Expand</button>
<button id='expand' class='btn expand' onclick='f1(this)'>Expand</button>
<button id='expand' class='btn expand' onclick='f1(this)'>Expand</button>
<button id='expand' class='btn expand' onclick='f1(this)'>Expand</button>


function f1(objButton)
    {
        if (objButton.innerHTML=="EXPAND") objButton.innerHTML = "MINIMIZE";
        else objButton.innerHTML = "EXPAND";
    }

This will work even if the url ends with a /:

var segments = window.location.pathname.split('/');
var toDelete = [];
for (var i = 0; i < segments.length; i++) {
    if (segments[i].length < 1) {
        toDelete.push(i);
    }
}
for (var i = 0; i < toDelete.length; i++) {
    segments.splice(i, 1);
}
var filename = segments[segments.length - 1];
console.log(filename);

Big O is the upper bound, while Omega is the lower bound. Theta requires both Big O and Omega, so that's why it's referred to as a tight bound (it must be both the upper and lower bound).

For example, an algorithm taking Omega(n log n) takes at least n log n time, but has no upper limit. An algorithm taking Theta(n log n) is far preferential since it takes at least n log n (Omega n log n) and no more than n log n (Big O n log n).

The ScriptIgnoreAttribute class is in the System.Web.Extensions.dll assembly (Located under Assemblies > Framework in the VS Reference Manager). You have to add a reference to that assembly in your class library project.

You can find this information at top of the MSDN page for the ScriptIgnoreAttribute class.

First of all, don't use different encodings. It leads to a mess, and UTF-8 is definitely the one you should be using everywhere.

Chances are your input is not ISO-8859-1, but something else (ISO-8859-15, Windows-1252). To convert from those, use iconv or mb_convert_encoding.

Nevertheless, utf8_encode and utf8_decode should work for ISO-8859-1. It would be nice if you could post a link to a file or a uuencoded or base64 example string for which the conversion fails or yields unexpected results.

You totally can with CSS3:

body {
    background-image: url(images/bg-body.png); 
    background-size: 100%; /* size the background image at 100% like any responsive img tag */
    background-position: top center;
    background-repeat:no-repeat;
 }

This will size a background image to 100% of the width of the body element and will then re-size the background accordingly as the body element re-sizes for smaller resolutions.

Here is the example: http://www.sccc.premiumdw.com/examples/resize-background-images-with-css/

Please make sure that all properties are both the getter and setter. In case, any property is getter only, it will cause the reverting the List to original data as the JSON string is typed.

Please refer to the following code snippet for the same: Model:

 public class Person
{
    public int ID { get; set; }
    // following 2 lines are cause of error
    //public string Name { get { return string.Format("{0} {1}", First, Last); } }
    //public string Country { get { return Countries[CountryID]; } }
    public int CountryID { get; set; }
    public bool Active { get; set; }
    public string First { get; set; }
    public string Last { get; set; }
    public DateTime Hired { get; set; }
}
public class ModelObj
    {
        public string Str { get; set; }
        public List<Person> Persons { get; set; }
    }

Controller:

 [HttpPost]
    public ActionResult Index(FormCollection collection)
    {
        var data = new ModelObj();
        data.Str = (string)collection.GetValue("Str").ConvertTo(typeof(string));
        var personsString = (string)collection.GetValue("Persons").ConvertTo(typeof(string));
        using (var textReader = new StringReader(personsString))
        {
            using (var reader = new JsonTextReader(textReader))
            {
                data.Persons = new JsonSerializer().Deserialize(reader, typeof(List<Person>)) as List<Person>; 
            }
        }

        return View(data);
    }

Another approach, which is the standard way since DOM2 to bind this within the event listener, that let you always remove the listener (among other benefits), is the handleEvent(evt)method from the EventListener interface:

var obj = {
  handleEvent(e) {
    // always true
    console.log(this === obj);
  }
};

document.body.addEventListener('click', obj);

Detailed information about using handleEvent can be found here: https://medium.com/@WebReflection/dom-handleevent-a-cross-platform-standard-since-year-2000-5bf17287fd38

The easiest way to do that would be to use the Params plugin, introduced in beta5. It has utility methods to make it easy to access different types of parameters. As always, reading the tests can prove valuable to understand how something is supposed to be used.

Get a single value

To get the value of a named parameter in a controller, you will need to select the appropriate method for the type of parameter you are looking for and pass in the name.

Examples:

$this->params()->fromPost('paramname');   // From POST
$this->params()->fromQuery('paramname');  // From GET
$this->params()->fromRoute('paramname');  // From RouteMatch
$this->params()->fromHeader('paramname'); // From header
$this->params()->fromFiles('paramname');  // From file being uploaded

Default values

All of these methods also support default values that will be returned if no parameter with the given name is found.

Example:

$orderBy = $this->params()->fromQuery('orderby', 'name');

When visiting http://example.com/?orderby=birthdate, $orderBy will have the value birthdate.
When visiting http://example.com/, $orderBy will have the default value name.
 

Get all parameters

To get all parameters of one type, just don't pass in anything and the Params plugin will return an array of values with their names as keys.

Example:

$allGetValues = $this->params()->fromQuery(); // empty method call

When visiting http://example.com/?orderby=birthdate&filter=hasphone $allGetValues will be an array like

array(
    'orderby' => 'birthdate',
    'filter'  => 'hasphone',
);

Not using Params plugin

If you check the source code for the Params plugin, you will see that it's just a thin wrapper around other controllers to allow for more consistent parameter retrieval. If you for some reason want/need to access them directly, you can see in the source code how it's done.

Example:

$this->getRequest()->getRequest('name', 'default');
$this->getEvent()->getRouteMatch()->getParam('name', 'default');

NOTE: You could have used the superglobals $_GET, $_POST etc., but that is discouraged.

I used the following code, it's working!

using System.Data.OleDb;
using System.IO;
using System.Text.RegularExpressions;

private void btopen_Click(object sender, EventArgs e)
{
   try
   {
     OpenFileDialog openFileDialog1 = new OpenFileDialog();  //create openfileDialog Object
     openFileDialog1.Filter = "XML Files (*.xml; *.xls; *.xlsx; *.xlsm; *.xlsb) |*.xml; *.xls; *.xlsx; *.xlsm; *.xlsb";//open file format define Excel Files(.xls)|*.xls| Excel Files(.xlsx)|*.xlsx| 
     openFileDialog1.FilterIndex = 3;

     openFileDialog1.Multiselect = false;        //not allow multiline selection at the file selection level
     openFileDialog1.Title = "Open Text File-R13";   //define the name of openfileDialog
     openFileDialog1.InitialDirectory = @"Desktop"; //define the initial directory

     if (openFileDialog1.ShowDialog() == DialogResult.OK)        //executing when file open
     {
       string pathName = openFileDialog1.FileName;
       fileName = System.IO.Path.GetFileNameWithoutExtension(openFileDialog1.FileName);
       DataTable tbContainer = new DataTable();
       string strConn = string.Empty;
       string sheetName = fileName;

       FileInfo file = new FileInfo(pathName);
       if (!file.Exists) { throw new Exception("Error, file doesn't exists!"); }
       string extension = file.Extension;
       switch (extension)
       {
          case ".xls":
                   strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + pathName + ";Extended Properties='Excel 8.0;HDR=Yes;IMEX=1;'";
                   break;
          case ".xlsx":
                   strConn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + pathName + ";Extended Properties='Excel 12.0;HDR=Yes;IMEX=1;'";
                   break;
          default:
                   strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + pathName + ";Extended Properties='Excel 8.0;HDR=Yes;IMEX=1;'";
                   break;
         }
         OleDbConnection cnnxls = new OleDbConnection(strConn);
         OleDbDataAdapter oda = new OleDbDataAdapter(string.Format("select * from [{0}$]", sheetName), cnnxls);
         oda.Fill(tbContainer);

         dtGrid.DataSource = tbContainer;
       }

     }
     catch (Exception)
     {
        MessageBox.Show("Error!");
     }
  }

The first example doesn't work because you can't assign values to arrays - arrays work (sort of) like const pointers in this respect. What you can do though is copy a new value into the array:

strcpy(p.name, "Jane");

Char arrays are fine to use if you know the maximum size of the string in advance, e.g. in the first example you are 100% sure that the name will fit into 19 characters (not 20 because one character is always needed to store the terminating zero value).

Conversely, pointers are better if you don't know the possible maximum size of your string, and/or you want to optimize your memory usage, e.g. avoid reserving 512 characters for the name "John". However, with pointers you need to dynamically allocate the buffer they point to, and free it when not needed anymore, to avoid memory leaks.

Update: example of dynamically allocated buffers (using the struct definition in your 2nd example):

char* firstName = "Johnnie";
char* surname = "B. Goode";
person p;

p.name = malloc(strlen(firstName) + 1);
p.surname = malloc(strlen(surname) + 1);

p.age = 25;
strcpy(p.name, firstName);
strcpy(p.surname, surname);

printf("Name: %s; Age: %d\n",p.name,p.age);

free(p.surname);
free(p.name);

Try to use minus sign for count from backside

<script>
    $(document).ready(function () {
        $('#example-2').DataTable({               
            'order':[],
            'columnDefs': [{
                "targets": [-1],
                "orderable": false
            }]
        });
    });
</script>

Just throw some light in to some issues related to this control.

Date picker is not a standard control that comes with office package. So developers encountered issues like missing date picker controls when application deployed in some other machiens/versions of office. In order to use it you have to activate the reference to the .dll, .ocx file that contains it.

In the event of a missing date picker, you have to replace MSCOMCT2.OCX file in System or System32 directory and register it properly. Try this link to do the proper replacement of the file.

In the VBA editor menu bar-> select tools-> references and then find the date picker reference and check it.

If you need the file, download MSCOMCT2.OCX from here.

2020 - NOV

This worked for me:

final File file = new File(getFilesDir(), "test.wav");//OR path to existing file
mediaPlayer = MediaPlayer.create(getApplicationContext(), Uri.fromFile(file));
mediaPlayer.start();

In the JavaScript (or any ECMAScript) language, in particular, closures are useful in hiding the implementation of functionality while still revealing the interface.

For example, imagine you are writing a class of date utility methods and you want to allow users to look up weekday names by index, but you don't want them to be able to modify the array of names you use under the hood.

var dateUtil = {
  weekdayShort: (function() {
    var days = ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun'];
    return function(x) {
      if ((x != parseInt(x)) || (x < 1) || (x > 7)) {
        throw new Error("invalid weekday number");
      }
      return days[x - 1];
    };
  }())
};

Note that the days array could simply be stored as a property of the dateUtil object, but then it would be visible to users of the script and they could even change it if they wanted, without even needing your source code. However, since it's enclosed by the anonymous function which returns the date lookup function it is only accessible by the lookup function so it is now tamperproof.

"The == operator checks to see if two Objects are exactly the same Object."

http://leepoint.net/notes-java/data/strings/12stringcomparison.html

String is an Object in java, so it falls into that category of comparison rules.

You can use the below for passing the raw text.

axios.post(
        baseUrl + 'applications/' + appName + '/dataexport/plantypes' + plan, 
        body, 
        {
            headers: { 
                'Authorization': 'Basic xxxxxxxxxxxxxxxxxxx',
                'Content-Type' : 'text/plain' 
            }
        }
).then(response => {
    this.setState({data:response.data});
    console.log(this.state.data);
});

Just have your raw text within body or pass it directly within quotes as 'raw text to be sent' in place of body.

The signature of the axios post is axios.post(url[, data[, config]]), so the data is where you pass your request body.

With .Net Core it is now very easy:

1. You go and find JSON URL on your swagger page:

2. Click that link and copy the URL
3. Now go to Postman and click Import:

4. Select what you need and you end up with a nice collection of endpoints:

Easy and better than str_replace:

<?php
$arr = array(
    "http://" => "http://www.",
    "w" => "W",
    "d" => "D");

    $word = "http://desiweb.ir";
    echo strtr($word,$arr);

Simplest way I've found:

in your activity XML add these lines:

<ListView 
... 
android:choiceMode="singleChoice"
android:listSelector="#666666"
/>

or programatically set these properties:

listView.setSelector(Drawable selector)
listView.setSelector(int resourceId)

My particular example:

   <ListView
            android:choiceMode="singleChoice"
            android:listSelector="#666666"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:id="@+id/listView"/>

Did you put \ in the original code?

urlToVisit = 'http://chartapi.finance.yahoo.com/instrument/1.0/' \
              + stock + '/chartdata;type=quote;range=5d/csv'

If you omit it, it could be a cause of the exception:

>>> stock = 'GOOG'
>>> urlToVisit = 'http://chartapi.finance.yahoo.com/instrument/1.0/'
>>> + stock + '/chartdata;type=quote;range=5d/csv'
Traceback (most recent call last):

BTW, string(e) should be str(e).

So, this is an awfully old question which already has an accepted answer, but I believe that this answer would have been chosen had it been posted four years ago.

I solved this purely with CSS, and with NO EXTRA DOM ELEMENTS! This means that the two colors are purely that, just background colors of ONE ELEMENT, not the background color of two.

I used a gradient and, because I set the color stops so closely together, it looks as if the colors are distinct and that they do not blend.

Here is the gradient in native syntax:

background: repeating-linear-gradient(#74ABDD, #74ABDD 49.9%, #498DCB 50.1%, #498DCB 100%);

Color #74ABDD starts at 0% and is still #74ABDD at 49.9%.

Then, I force the gradient to shift to my next color within 0.2% of the elements height, creating what appears to be a very solid line between the two colors.

Here is the outcome:

And here's my JSFiddle!

Have fun!

Based on Cobbal's answer, here's what I did:

In my JavaScript I put the following:

setInterval(function() {
  if(window.clear) {
    window.clear();
    console.log("this is highly repeated code");
  }
}, 10);

The conditional code won't run until you ASSIGN window.clear (meaning your log is empty until you do so). IN THE DEBUG CONSOLE TYPE:

window.clear = clear;

Violà - a log that clears itself.

Greedy means it will consume your pattern until there are none of them left and it can look no further.

Lazy will stop as soon as it will encounter the first pattern you requested.

One common example that I often encounter is \s*-\s*? of a regex ([0-9]{2}\s*-\s*?[0-9]{7})

The first \s* is classified as greedy because of * and will look as many white spaces as possible after the digits are encountered and then look for a dash character "-". Where as the second \s*? is lazy because of the present of *? which means that it will look the first white space character and stop right there.

I think the concept of "notification sound" is someway wrong for Android UI.

The Android expected behaviour is to use the standard Notification to alert the user. If you play a notification sound without the status bar icon, you get the user confused ("what was that sound? there is no icon here, maybe I have hearing problems?").

How to set sound on a notification is, for example, here: Setting sound for notification

grid is not a global, it is local to the main function. Change this:

int nonrecursivecountcells(color[ROW_SIZE][COL_SIZE], int row, int column)

to this:

int nonrecursivecountcells(color grid[ROW_SIZE][COL_SIZE], int row, int column)

Basically you forgot to give that first param a name, grid will do since it matches your code.

UPDATE: Using HTTPS is now exempt from the ERN as of late September, 2016

https://stackoverflow.com/a/40919650/4976373

Unfortunately, I believe that your app "contains encryption" in terms of US BIS even if you just use HTTPS (if your app is not an exception included in question 2).

Quote from FAQ on iTunes Connect:

"How do I know if I can follow the Exporter Registration and Reporting (ERN) process?

If your app uses, accesses, implements or incorporates industry standard encryption algorithms for purposes other than those listed as exemptions under question 2, you need to submit for an ERN authorization. Examples of standard encryption are: AES, SSL, https. This authorization requires that you submit an annual report to two U.S. Government agencies with information about your app every January. "

"2nd Question: Does your product qualify for any exemptions provided under category 5 part 2?

There are several exemptions available in US export regulations under Category 5 Part 2 (Information Security & Encryption regulations) for applications and software that use, access, implement or incorporate encryption.

All liabilities associated with misinterpretation of the export regulations or claiming exemption inaccurately are borne by owners and developers of the apps.

You can answer “YES” to the question if you meet any of the following criteria:

(i) if you determine that your app is not classified under Category 5, Part 2 of the EAR based on the guidance provided by BIS at encryption question. The Statement of Understanding for medical equipment in Supplement No. 3 to Part 774 of the EAR can be accessed at Electronic Code of Federal Regulations site. Please visit the Question #15 in the FAQ section of the encryption page for sample items BIS has listed that can claim Note 4 exemptions.

(ii) your app uses, accesses, implements or incorporates encryption for authentication only

(iii) your app uses, accesses, implements or incorporates encryption with key lengths not exceeding 56 bits symmetric, 512 bits asymmetric and/or 112 bit elliptic curve

(iv) your app is a mass market product with key lengths not exceeding 64 bits symmetric, or if no symmetric algorithms, not exceeding 768 bits asymmetric and/or 128 bits elliptic curve.

Please review Note 3 in Category 5 Part 2 to understand the criteria for mass market definition.

(v) your app is specially designed and limited for banking use or ‘money transactions.’ The term ‘money transactions’ includes the collection and settlement of fares or credit functions.

(vi) the source code of your app is “publicly available”, your app distributed at free of cost to general public, and you have met the notification requirements provided under 740.13.(e).

Please visit encryption web page in case you need further help in determining if your app qualifies for any exemptions.

If you believe that your app qualifies for an exemption, please answer “YES” to the question."

My favorite...

SELECT objParent.name AS parent, obj.name, col.*
FROM sysobjects obj 
    LEFT JOIN syscolumns col
        ON obj.id = col.id
    LEFT JOIN sysobjects objParent
        ON objParent.id = obj.parent_obj
WHERE col.name LIKE '%Comment%'
   OR obj.name LIKE '%Comment%'

Above I'm searching for "Comment".

Drop the percent signs if you want a direct match.

This searches tables, fields and things like primary key names, constraints, views, etc.

And when you want to search in StoredProcs after monkeying with the tables (and need to make the procs match), use the following...

SELECT name
FROM sys.procedures
WHERE OBJECT_DEFINITION(OBJECT_ID) LIKE '%Comment%'

Hope that helps, I find these two queries to be extremely useful.

Apple annoyingly rejects many HTML5 web standards on their iOS devices, for a variety of business reasons. Ultimately, you can't pre-load or auto-play sound files before a touch event, it only plays one sound at a time, and it doesn't support Ogg/Vorbis. However, I did find one nifty workaround to let you have a little more control over the audio.

<audio id="soundHandle" style="display:none;"></audio>

<script type="text/javascript">

var soundHandle = document.getElementById('soundHandle');

$(document).ready(function() {
    addEventListener('touchstart', function (e) {
        soundHandle.src = 'audio.mp3';
        soundHandle.loop = true;
        soundHandle.play();
        soundHandle.pause();
    });
});

</script>

Basically, you start playing the audio file on the very first touch event, then you pause it immediately. Now, you can use the soundHandle.play() and soundHandle.pause() commands throughout your Javascript and control the audio without touch events. If you can time it perfectly, just have the pause come in right after the sound is over. Then next time you play it again, it will loop back to the beginning. This won't resolve all the mess Apple has made here, but it's one solution.

You will need to import the other file as a module like this:

import Math

If you don't want to prefix your Calculate function with the module name then do this:

from Math import Calculate

If you want to import all members of a module then do this:

from Math import *

Edit: Here is a good chapter from Dive Into Python that goes a bit more in depth on this topic.

LIBRARY_PATH is used by gcc before compilation to search directories containing static and shared libraries that need to be linked to your program.

LD_LIBRARY_PATH is used by your program to search directories containing shared libraries after it has been successfully compiled and linked.

EDIT: As pointed below, your libraries can be static or shared. If it is static then the code is copied over into your program and you don't need to search for the library after your program is compiled and linked. If your library is shared then it needs to be dynamically linked to your program and that's when LD_LIBRARY_PATH comes into play.

Obviously you mean the baseurl. If so:

base url: URL to your CodeIgniter root. Typically this will be your base URL, | WITH a trailing slash.

Root in codeigniter specifically means that the position where you can append your controller to your url.

For example, if the root is localhost/ci_installation/index.php/, then to access the mycont controller you should go to localhost/ci_installation/index.php/mycont.

So, instead of writing such a long link you can (after loading "url" helper) , replace the term localhost/ci_installation/index.php/ by base_url() and this function will return the same string url.

NOTE: if you hadn't appended index.php/ to your base_url in your config.php, then if you use base_url(), it will return something like that localhost/ci_installation/mycont. And that will not work, because you have to access your controllers from index.php, instead of that you can place a .htaccess file to your codeigniter installation position. Cope that the below code to it:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /imguplod/index.php/$1 [L]

And it should work :)

This is the right answer:

myPassedColor = "#ffff8c85" int colorInt = Color.parseColor(myPassedColor)

You can get data types from the information_schema (8.4 docs referenced here, but this is not a new feature):

=# select column_name, data_type from information_schema.columns
-# where table_name = 'config';
    column_name     | data_type 
--------------------+-----------
 id                 | integer
 default_printer_id | integer
 master_host_enable | boolean
(3 rows)

Simply this line of code will disable all input elements

$('#yourdiv *').prop('disabled', true);

There are some online services for obfuscate php to hide the code from others. This is one Right Coder's Free Obfuscator Online

@Glavic is right. "Nothing is bulletproof". You can encode your source code and hide from bigger programmers, not from experts.

4.19.4 The instanceof operator

The instanceof operator requires the left operand to be of type Any, an object type, or a type parameter type, and the right operand to be of type Any or a subtype of the 'Function' interface type. The result is always of the Boolean primitive type.

So you could use

mySprite instanceof Sprite;

Note that this operator is also in ActionScript but it shouldn't be used there anymore:

The is operator, which is new for ActionScript 3.0, allows you to test whether a variable or expression is a member of a given data type. In previous versions of ActionScript, the instanceof operator provided this functionality, but in ActionScript 3.0 the instanceof operator should not be used to test for data type membership. The is operator should be used instead of the instanceof operator for manual type checking, because the expression x instanceof y merely checks the prototype chain of x for the existence of y (and in ActionScript 3.0, the prototype chain does not provide a complete picture of the inheritance hierarchy).

TypeScript's instanceof shares the same problems. As it is a language which is still in its development I recommend you to state a proposal of such facility.
