In my case, I was moving a SProc between servers and the profile name in my TSQL code did not match the profile name on the new server.

Updating TSQL profile name == New server profile name fixed the error for me.

Here is one way to do it from an article titled "Format query output into an HTML table - the easy way [archive]". You would need to substitute the details of your own query for the ones in this example, which gets a list of tables and a row count.

declare @body varchar(max)

set @body = cast( (
select td = dbtable + '</td><td>' + cast( entities as varchar(30) ) + '</td><td>' + cast( rows as varchar(30) )
from (
      select dbtable  = object_name( object_id ),
             entities = count( distinct name ),
             rows     = count( * )
      from sys.columns
      group by object_name( object_id )
      ) as d
for xml path( 'tr' ), type ) as varchar(max) )

set @body = '<table cellpadding="2" cellspacing="2" border="1">'
          + '<tr><th>Database Table</th><th>Entity Count</th><th>Total Rows</th></tr>'
          + replace( replace( @body, '&lt;', '<' ), '&gt;', '>' )
          + '</table>'

print @body

Once you have @body, you can then use whatever email mechanism you want.

You can send email natively from within SQL Server using Database Mail. This is a great tool for notifying sysadmins about errors or other database events. You could also use it to send a report or an email message to an end user. The basic syntax for this is:

EXEC msdb.dbo.sp_send_dbmail  
@recipients='[email protected]',
@subject='Testing Email from SQL Server',
@body='<p>It Worked!</p><p>Email sent successfully</p>',
@body_format='HTML',
@from_address='Sender Name <[email protected]>',
@reply_to='[email protected]'

Before use, Database Mail must be enabled using the Database Mail Configuration Wizard, or sp_configure. A database or Exchange admin might need to help you configure this. See http://msdn.microsoft.com/en-us/library/ms190307.aspx and http://www.codeproject.com/Articles/485124/Configuring-Database-Mail-in-SQL-Server for more information.

This package seems to be a good solution for the underlying issue of having non-unique IDs in your DOM across multiple components:

vue-uniq-ids

It is a trend to use components. Components are cool, they are small, obvious, easy to use and modular. Untill it comes to the id property.

Some HTML tag attributes requires using an id property, like label[for], input[form] and many of aria-* attributes. And the problem with the id is that it is not modular. If several id properties on the page will has the same value they can affect each other.

VueUniqIds helps you to get rid of this problem. It provides the set of id-related directives which value is automatically modified by adding unique string while keeping the attrbitue easy to read.

Virtual scrolling is another way to improve scrolling performance when dealing with huge lists and large dataset.

One way to implement this is by using Angular Material md-virtual-repeat as it is demonstrated on this Demo with 50,000 items

Taken straight from the documentation of virtual repeat:

Virtual repeat is a limited substitute for ng-repeat that renders only enough dom nodes to fill the container and recycling them as the user scrolls.

You need to consider your objectives:

1) Are you trying to prevent people from reading/modifying your code? If yes, you'll need an obfuscation/encryption tool. I've used Zend Guard with good success.

2) Are you trying to prevent unauthorized redistribution of your code?? A EULA/proprietary license will give you the legal power to prevent that, but won't actually stop it. An key/activation scheme will allow you to actively monitor usage, but can be removed unless you also encrypt your code. Zend Guard also has capabilities to lock a particular script to a particular customer machine and/or create time limited versions of the code if that's what you want to do.

I'm not familiar with vBulletin and the like, but they'd either need to encrypt/obfuscate or trust their users to do the right thing. In the latter case they have the protection of having a EULA which prohibits the behaviors they find undesirable, and the legal system to back up breaches of the EULA.

If you're not prepared/able to take legal action to protect your software and you don't want to encrypt/obfuscate, your options are a) Release it with a EULA so you're have a legal option if you ever need it and hope for the best, or b) consider whether an open source license might be more appropriate and just allow redistribution.

I use LogParser to generate graphs and look for elements in IIS logs.

If date in string format convert it to date format for each object :

String argmodifiledDate = "2014-04-06 22:26:15";
SimpleDateFormat  format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");  
            try
            {
                this.modifiledDate = format.parse(argmodifiledDate);
            }
            catch (ParseException e)
            {

                e.printStackTrace();
            }

Then sort the arraylist in descending order :

ArrayList<Document> lstDocument= this.objDocument.getArlstDocuments();
        Collections.sort(lstDocument, new Comparator<Document>() {
              public int compare(Document o1, Document o2) {
                  if (o1.getModifiledDate() == null || o2.getModifiledDate() == null)
                    return 0;     
                  return o2.getModifiledDate().compareTo(o1.getModifiledDate());
              }
            });

<!DOCTYPE html>
<html lang="en">
<head>
    <meta http-equiv="X-UA-Compatible" content="IE=edge" />

The meta tag must be the first tag after the head tag or it will not work.

git add . equals git add -A . adds files to index only from current and children folders.

git add -A adds files to index from all folders in working tree.

P.S.: information relates to Git 2.0 (2014-05-28).

Use a colon:

: ${A:=hello}

The colon is a null command that does nothing and ignores its arguments. It is built into bash so a new process is not created.

Try to uninstall angular and then reinstall

npm uninstall --save @angular/(then whatever component you want deleted)

after that, a box with babyblue color border will appear with suggestion to update and install angular back up.

array.push is like List<T>.Add. .NET arrays are fixed-size so you can't actually add a new element. All you can do is create a new array that is one element larger than the original and then set that last element, e.g.

Array.Resize(ref myArray, myArray.Length + 1);
myArray[myArray.GetUpperBound(0)] = newValue;

EDIT:

I'm not sure that this answer actually applies given this edit to the question:

The crux of the matter is that the element needs to be added into the first empty slot in an array, lie a Java push function would do.

The code I provided effectively appends an element. If the aim is to set the first empty element then you could do this:

int index = Array.IndexOf(myArray, null);

if (index != -1)
{
    myArray[index] = newValue;
}

EDIT:

Here's an extension method that encapsulates that logic and returns the index at which the value was placed, or -1 if there was no empty element. Note that this method will work for value types too, treating an element with the default value for that type as empty.

public static class ArrayExtensions
{
    public static int Push<T>(this T[] source, T value)
    {
        var index = Array.IndexOf(source, default(T));

        if (index != -1)
        {
            source[index] = value;
        }

        return index;
    }
}

I'm hoping you are having the same problem that I had... my issue was simple: Make a fixed textarea with locked percentages inside the container (I'm new to CSS/JS/HTML, so bear with me, if I don't get the lingo correct) so that no matter the device it's displaying on, the box filling the container (the table cell) takes up the correct amount of space. Here's how I solved it:

<table width=100%>
    <tr class="idbbs">
        B.S.:
    </tr></br>
    <tr>
        <textarea id="bsinpt"></textarea>
    </tr>
</table>

Then CSS Looks like this...

#bsinpt
{
    color: gainsboro;
    float: none;
    background: black;
    text-align: left;
    font-family: "Helvetica", "Tahoma", "Verdana", "Arial Black", sans-serif;
    font-size: 100%;
  position: absolute;
  min-height: 60%;
  min-width: 88%;
  max-height: 60%;
  max-width: 88%;
  resize: none;
    border-top-color: lightsteelblue;
    border-top-width: 1px;
    border-left-color: lightsteelblue;
    border-left-width: 1px;
    border-right-color: lightsteelblue;
    border-right-width: 1px;
    border-bottom-color: lightsteelblue;
    border-bottom-width: 1px;
}

Sorry for the sloppy code block here, but I had to show you what's important and I don't know how to insert quoted CSS code on this website. In any case, to ensure you see what I'm talking about, the important CSS is less indented here...

What I then did (as shown here) is very specifically tweak the percentages until I found the ones that worked perfectly to fit display, no matter what device screen is used.

Granted, I think the "resize: none;" is overkill, but better safe than sorry and now the consumers will not have anyway to resize the box, nor will it matter what device they are viewing it from.

It works great.

See the Integer class and the static parseInt() method:

http://developer.android.com/reference/java/lang/Integer.html

Integer.parseInt(et.getText().toString());

You will need to catch NumberFormatException though in case of problems whilst parsing, so:

int myNum = 0;

try {
    myNum = Integer.parseInt(et.getText().toString());
} catch(NumberFormatException nfe) {
   System.out.println("Could not parse " + nfe);
} 

Also could be like this

df.filter(col('bar').isin(['a','b']) == False).show()

You can do this simply with a function. For example:

def script():
    # program code here...
    restart = raw_input("Would you like to restart this program?")
    if restart == "yes" or restart == "y":
        script()
    if restart == "n" or restart == "no":
        print "Script terminating. Goodbye."
script()

Of course you can change a lot of things here. What is said, what the script will accept as a valid input, the variable and function names. You can simply nest the entire program in a user-defined function (Of course you must give everything inside an extra indent) and have it restart at anytime using this line of code: myfunctionname(). More on this here.

After formatting the previous answer to my own code, I have found an efficient way to copy all necessary data if you are attempting to paste the values returned via AutoFilter to a separate sheet.

With .Range("A1:A" & LastRow)
    .Autofilter Field:=1, Criteria1:="=*" & strSearch & "*"
    .Offset(1,0).SpecialCells(xlCellTypeVisible).Cells.Copy
    Sheets("Sheet2").activate
    DestinationRange.PasteSpecial
End With

In this block, the AutoFilter finds all of the rows that contain the value of strSearch and filters out all of the other values. It then copies the cells (using offset in case there is a header), opens the destination sheet and pastes the values to the specified range on the destination sheet.

If this error is gotten when using a rooted device's su prompt and not from emulator, disable SELinux first

setenforce 0

You may need to switch to shell user first for some pm operations

su shell

then re-run your pm command.

Same applies to am commands unavailable from su prompt.

As of August 2020, Google Play's In-App Review API is available and its straightforward implementation is correct as per this answer.

But if you wish add some display logic on top of it, use the Five-Star-Me library.

Set launch times and install days in the onCreate method of the MainActivity to configure the library.

  FiveStarMe.with(this)
      .setInstallDays(0) // default 10, 0 means install day.
      .setLaunchTimes(3) // default 10
      .setDebug(false) // default false
      .monitor();

Then place the below method call on any activity / fragment's onCreate / onViewCreated method to show the prompt whenever the conditions are met.

FiveStarMe.showRateDialogIfMeetsConditions(this); //Where *this* is the current activity.

Installation instructions:

You can download from jitpack.

Step 1: Add this to project (root) build.gradle.

allprojects {
  repositories {
    ...
    maven { url 'https://jitpack.io' }
  }
}

Step 2: Add the following dependency to your module (app) level build.gradle.

dependencies {
  implementation 'com.github.numerative:Five-Star-Me:2.0.0'
}

1. Goto File -> Invalidate caches / Restart
2. Shutdown Android Studio
3. Rename/remove .gradle folder in the user home directory
4. Restart Android Studio (It will download gradle metadata and data)
5. Gradle build succeed
6. Rebuild project. Done.

The problem is the )

Another option for an in-memory java cache is cache2k. The in-memory performance is superior to EHCache and google guava, see the cache2k benchmarks page.

The usage pattern is similar to other caches. Here is an example:

Cache<String,String> cache = new Cache2kBuilder<String, String>() {}
  .expireAfterWrite(5, TimeUnit.MINUTES)    // expire/refresh after 5 minutes
  .resilienceDuration(30, TimeUnit.SECONDS) // cope with at most 30 seconds
                                          // outage before propagating 
                                          // exceptions
  .refreshAhead(true)                       // keep fresh when expiring
  .loader(new CacheLoader<String, String>() {
    @Override
    public String load(final String key) throws Exception {
      return ....;
    }
  })
  .build();
String val = cache.peek("something");
cache.put("something", "hello");
val = cache.get("something");

If you have google guava as dependency then trying out guava cache, may be a good alternative.

var list = new List<string>();
var queryable = list.AsQueryable();

Add a reference to: System.Linq

As these answers are old, I found this alternative. It is very clean and works with just java annotations:

To fix it, create a “none static setter” to assign the injected value for the static variable. For example :

import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

@Component
public class GlobalValue {

public static String DATABASE;

@Value("${mongodb.db}")
public void setDatabase(String db) {
    DATABASE = db;
}
}

This is how I am checking if my app is in foreground. Note I am using AsyncTask as suggested by official Android documentation.`

`

    private class CheckIfForeground extends AsyncTask<Void, Void, Void> {
    @Override
    protected Void doInBackground(Void... voids) {

        ActivityManager activityManager = (ActivityManager) mContext.getSystemService(Context.ACTIVITY_SERVICE);
        List<ActivityManager.RunningAppProcessInfo> appProcesses = activityManager.getRunningAppProcesses();
        for (ActivityManager.RunningAppProcessInfo appProcess : appProcesses) {
            if (appProcess.importance == ActivityManager.RunningAppProcessInfo.IMPORTANCE_FOREGROUND) {
                Log.i("Foreground App", appProcess.processName);

                if (mContext.getPackageName().equalsIgnoreCase(appProcess.processName)) {
                    Log.i(Constants.TAG, "foreground true:" + appProcess.processName);
                    foreground = true;
                    // close_app();
                }
            }
        }
        Log.d(Constants.TAG, "foreground value:" + foreground);
        if (foreground) {
            foreground = false;
            close_app();
            Log.i(Constants.TAG, "Close App and start Activity:");

        } else {
            //if not foreground
            close_app();
            foreground = false;
            Log.i(Constants.TAG, "Close App");

        }

        return null;
    }
}

and execute AsyncTask like this. new CheckIfForeground().execute();

You can still use "Background" as the property name, as long as you give your window a name and use this name on the "Source" of the Binding.

A quick and simple way to fix this issue is to remove the @XmlElement(name="TimeSeries") from the top of the variable declaration statement protected List<TimeSeries> timeSeries; to the top of its getter, public List<TimeSeries> getTimeSeries().

Thus your ModeleREP class will look like:

@XmlRootElement(name="ModeleREP", namespace="urn:test:mod_rep.xsd")
public class ModeleREP {


  protected List<TimeSeries> timeSeries;

  @XmlElement(name="TimeSeries")
  public List<TimeSeries> getTimeSeries() {
    if (this.timeSeries == null) {
      this.timeSeries = new ArrayList<TimeSeries>();
    }
    return this.timeSeries;
  }

  public void setTimeSeries(List<TimeSeries> timeSeries) {
    this.timeSeries = timeSeries;
  }
}

Hope it helps!

• the image can't open in Photoshop
• Image size will be double

Code - 2 : to open image in image edition tools use code

by using code 1 it just create images but it not assign image marks.

I think this String.Equals is what you need.

Dim aaa = "12/31"
            Dim a = String.Equals(aaa, "06/30")

a will return false.

private boolean current;

public void setCurrent(boolean current){
    this.current=current;
}

public boolean hasCurrent(){
    return this.current;
}

EDIT:

After your comments this actually makes perfect sense why you don't get a histogram of each different value. There are 1.4 million rows, and ten discrete buckets. So apparently each bucket is exactly 10% (to within what you can see in the plot).

A quick rerun of your data:

In [25]: df.hist(column='Trip_distance')

Prints out absolutely fine.

The df.hist function comes with an optional keyword argument bins=10 which buckets the data into discrete bins. With only 10 discrete bins and a more or less homogeneous distribution of hundreds of thousands of rows, you might not be able to see the difference in the ten different bins in your low resolution plot:

In [34]: df.hist(column='Trip_distance', bins=50)

No one has mentioned this yet, and this may not be a common problem, but I had a similar problem with Xcode 5: Make sure you have a default keychain selected in the Mac's Keychain Access. I trying out a fresh install of Mountain Lion and deleted one keychain, which happened to be the default. After setting another keychain as the default (right-click on the keychain and select Make Keychain "Keychain_name" default"), Xcode was able to set up the valid signing identities.

There are several timezones in operation here:

1. Java's Date classes (util and sql), which have implicit timezones of UTC
2. The timezone your JVM is running in, and
3. the default timezone of your database server.

All of these can be different. Hibernate/JPA has a severe design deficiency in that a user cannot easily ensure that timezone information is preserved in the database server (which allows reconstruction of correct times and dates in the JVM).

Without the ability to (easily) store timezone using JPA/Hibernate then information is lost and once information is lost it becomes expensive to construct it (if at all possible).

I would argue that it is better to always store timezone information (should be the default) and users should then have the optional ability to optimize the timezone away (although it only really affects display, there is still an implicit timezone in any date).

Sorry, this post doesn't provide a work-around (that's been answered elsewhere) but it is a rationalization of why always storing timezone information around is important. Unfortunately it seems many Computer Scientists and programming practitioners argue against the need for timezones simply because they don't appreciate the "loss of information" perspective and how that makes things like internationalization very difficult - which is very important these days with web sites accessible by clients and people in your organization as they move around the world.

Every time someone uses double brace initialisation, a kitten gets killed.

Apart from the syntax being rather unusual and not really idiomatic (taste is debatable, of course), you are unnecessarily creating two significant problems in your application, which I've just recently blogged about in more detail here.

1. You're creating way too many anonymous classes

Each time you use double brace initialisation a new class is made. E.g. this example:

Map source = new HashMap(){{
    put("firstName", "John");
    put("lastName", "Smith");
    put("organizations", new HashMap(){{
        put("0", new HashMap(){{
            put("id", "1234");
        }});
        put("abc", new HashMap(){{
            put("id", "5678");
        }});
    }});
}};

... will produce these classes:

Test$1$1$1.class
Test$1$1$2.class
Test$1$1.class
Test$1.class
Test.class

That's quite a bit of overhead for your classloader - for nothing! Of course it won't take much initialisation time if you do it once. But if you do this 20'000 times throughout your enterprise application... all that heap memory just for a bit of "syntax sugar"?

2. You're potentially creating a memory leak!

If you take the above code and return that map from a method, callers of that method might be unsuspectingly holding on to very heavy resources that cannot be garbage collected. Consider the following example:

public class ReallyHeavyObject {

    // Just to illustrate...
    private int[] tonsOfValues;
    private Resource[] tonsOfResources;

    // This method almost does nothing
    public Map quickHarmlessMethod() {
        Map source = new HashMap(){{
            put("firstName", "John");
            put("lastName", "Smith");
            put("organizations", new HashMap(){{
                put("0", new HashMap(){{
                    put("id", "1234");
                }});
                put("abc", new HashMap(){{
                    put("id", "5678");
                }});
            }});
        }};

        return source;
    }
}

The returned Map will now contain a reference to the enclosing instance of ReallyHeavyObject. You probably don't want to risk that:

_{Image from http://blog.jooq.org/2014/12/08/dont-be-clever-the-double-curly-braces-anti-pattern/}

3. You can pretend that Java has map literals

To answer your actual question, people have been using this syntax to pretend that Java has something like map literals, similar to the existing array literals:

String[] array = { "John", "Doe" };
Map map = new HashMap() {{ put("John", "Doe"); }};

Some people may find this syntactically stimulating.

Just in case if anyone is interested in labeling horizontal barplot graph, I modified Sharon's answer as below:

def show_values_on_bars(axs, h_v="v", space=0.4):
    def _show_on_single_plot(ax):
        if h_v == "v":
            for p in ax.patches:
                _x = p.get_x() + p.get_width() / 2
                _y = p.get_y() + p.get_height()
                value = int(p.get_height())
                ax.text(_x, _y, value, ha="center") 
        elif h_v == "h":
            for p in ax.patches:
                _x = p.get_x() + p.get_width() + float(space)
                _y = p.get_y() + p.get_height()
                value = int(p.get_width())
                ax.text(_x, _y, value, ha="left")

    if isinstance(axs, np.ndarray):
        for idx, ax in np.ndenumerate(axs):
            _show_on_single_plot(ax)
    else:
        _show_on_single_plot(axs)

h_v - Whether the barplot is horizontal or vertical. "h" represents the horizontal barplot, "v" represents the vertical barplot.

space - The space between value text and the top edge of the bar. Only works for horizontal mode.

Example:

show_values_on_bars(sns_t, "h", 0.3)

KeyPress is only fired by printable characters and is fired after the KeyDown event. Depending on the typing delay settings there can be multiple KeyDown and KeyPress events but only one KeyUp event.

KeyDown
KeyPress
KeyUp

@ECHO OFF
:Loop
IF "%1"=="" GOTO Continue
SHIFT
GOTO Loop
:Continue

Note: IF "%1"=="" will cause problems if %1 is enclosed in quotes itself.

In that case, use IF [%1]==[] or, in NT 4 (SP6) and later only, IF "%~1"=="" instead.

If you're using it in a switch case then you need to get the type of the enum even before you plug that value in the switch. For instance :

SomeEnum someEnum = SomeEnum.values()[1];

switch (someEnum) {
            case GRAPES:
            case BANANA: ...

And the enum is like:

public enum SomeEnum {

    GRAPES("Grapes", 0),
    BANANA("Banana", 1),

    private String typeName;
    private int typeId;

    SomeEnum(String typeName, int typeId){
        this.typeName = typeName;
        this.typeId = typeId;
    }
}

val navigationView: NavigationView =  findViewById(R.id.nv)
val header: View = navigationView.getHeaderView(0)
val tv: TextView = header.findViewById(R.id.profilename)
tv.text = "Your_Text"

This will fix your problem <3

If you have an array of arrays of data:

rows = [["a1", "a2", "a3"],["b1", "b2", "b3", "b4"], ["c1", "c2", "c3"]]

Then you can write this to a file with the following, which I think is much simpler:

require "csv"
File.write("ss.csv", rows.map(&:to_csv).join)

mylist = [20, 30, 25, 20]

kl = {i: mylist.count(i) for i in mylist if mylist.count(i) > 1 }

print(kl)

Scripted languages

Scripting languages are interpreted within another program. JavaScript is embedded within a browser and interpreted by that browser.

Examples of scripting languages

1. JavaScript
2. Perl
3. Python

Advantages of Scripting languages:

1. Simple – Scripting languages are easier to write than programming language.

2. Fewer Lines of Code (LOC)

Programmed languages

Programming languages like Java are compiled and not interpreted by another application in the same way.

Examples programming languages

1. C
2. C++ and
3. Java

You can use:

var tomorrow = new Date();
tomorrow.setDate(new Date().getDate()+1);

For example, since there are 30 days in April, the following code will output May 1:

var day = new Date('Apr 30, 2000');
console.log(day); // Apr 30 2000

var nextDay = new Date(day);
nextDay.setDate(day.getDate() + 1);
console.log(nextDay); // May 01 2000    

See fiddle.

according to NPM Doc

So it seems that by running npm install package_name, the package dependency should be automatically added to package.json right?

just add .setMaster("local") to your code as shown below:

val conf = new SparkConf().setAppName("Second").setMaster("local") 

It worked for me ! Happy coding !

variable=10
f=open("fileName.txt","w+") # file name and mode
for x in range(0,10):
    f.writelines('your text')
    f.writelines('if you want to add variable data'+str(variable))
    # to add data you only add String data so you want to type cast variable  
    f.writelines("\n")

I just use a bit of jQuery/javascript:

html:

<h1>Don't Print</h1>

<a data-target="#myModal" role="button" class="btn" data-toggle="modal">Launch modal</a>

<div class="modal fade hide" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel"      aria-hidden="true">
  <div class="modal-header">
    <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
     <h3 id="myModalLabel">Modal to print</h3>
  </div>
  <div class="modal-body">
    <p>Print Me</p>
  </div>
  <div class="modal-footer">
    <button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
    <button class="btn btn-primary" id="printButton">Print</button>
  </div>
</div>

js:

$('#printButton').on('click', function () {
    if ($('.modal').is(':visible')) {
        var modalId = $(event.target).closest('.modal').attr('id');
        $('body').css('visibility', 'hidden');
        $("#" + modalId).css('visibility', 'visible');
        $('#' + modalId).removeClass('modal');
        window.print();
        $('body').css('visibility', 'visible');
        $('#' + modalId).addClass('modal');
    } else {
        window.print();
    }
});

here is the fiddle

Try this script

<script language="JavaScript">
function fullScreen(theURL) {
window.open(theURL, '', 'fullscreen=yes, scrollbars=auto' );
}
</script>

For calling from script use this code,

window.fullScreen('fullscreen.jsp');

or with hyperlink use this

<a href="javascript:void(0);" onclick="fullScreen('fullscreen.jsp');"> 
Open in Full Screen Window</a>

In Swift :- var str_url = yourUrl.absoluteString

It will result a url in string.

Apparently in Android 2.2 there is a bug with SimpleDateFormat.

In order to use month names you have to define them yourself in your resources:

<string-array name="month_names">
    <item>January</item>
    <item>February</item>
    <item>March</item>
    <item>April</item>
    <item>May</item>
    <item>June</item>
    <item>July</item>
    <item>August</item>
    <item>September</item>
    <item>October</item>
    <item>November</item>
    <item>December</item>
</string-array>

And then use them in your code like this:

/**
 * Get the month name of a Date. e.g. January for the Date 2011-01-01
 * 
 * @param date
 * @return e.g. "January"
 */
public static String getMonthName(Context context, Date date) {

    /*
     * Android 2.2 has a bug in SimpleDateFormat. Can't use "MMMM" for
     * getting the Month name for the given Locale. Thus relying on own
     * values from string resources
     */

    String result = "";

    Calendar cal = Calendar.getInstance();
    cal.setTime(date);
    int month = cal.get(Calendar.MONTH);

    try {
        result = context.getResources().getStringArray(R.array.month_names)[month];
    } catch (ArrayIndexOutOfBoundsException e) {
        result = Integer.toString(month);
    }

    return result;
}

Assuming you are testing via mocha, you have to run your tests using the mocha command instead of the node executable.

So if you haven't already, make sure you do npm install mocha -g. Then just run mocha in your project's root directory.

You can also use the card layout like below

  <androidx.cardview.widget.CardView
        android:layout_width="match_parent"
        android:layout_height="60dp"
        app:cardCornerRadius="30dp">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"

            >

            <TextView
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:gravity="center"
                android:text="Template"

                />

        </LinearLayout>

    </androidx.cardview.widget.CardView>

If you have recently updated to ubuntu 14.04 here is the fix to this problem:

$ sudo mv /etc/php5/conf.d/mcrypt.ini /etc/php5/mods-available/
$ sudo php5enmod mcrypt
$ sudo service apache2 restart

Follow these steps:

1. Remove Service Reference
2. Close Visual Studio
3. Delete /Bin and /Obj folders.
4. Open Visual Studio.
5. Add the Service Reference.
6. You're Welcome :)

It seems that some references are left in these folders when adding the service, causing errors during the auto-generation of code.

Just create a new branch:

git checkout -b newBranch

And if you do git status you'll see that the state of the code hasn't changed and you can commit it to the new branch.

Reference:

In view.py Implement function like,

def download(request, id):
    obj = your_model_name.objects.get(id=id)
    filename = obj.model_attribute_name.path
    response = FileResponse(open(filename, 'rb'))
    return response

In my opinion SET XACT_ABORT ON was made obsolete by the addition of BEGIN TRY/BEGIN CATCH in SQL 2k5. Before exception blocks in Transact-SQL it was really difficult to handle errors and unbalanced procedures were all too common (procedures that had a different @@TRANCOUNT at exit compared to entry).

With the addition of Transact-SQL exception handling is much easier to write correct procedures that are guaranteed to properly balance the transactions. For instance I use this template for exception handling and nested transactions:

create procedure [usp_my_procedure_name]
as
begin
    set nocount on;
    declare @trancount int;
    set @trancount = @@trancount;
    begin try
        if @trancount = 0
            begin transaction
        else
            save transaction usp_my_procedure_name;

        -- Do the actual work here

lbexit:
        if @trancount = 0   
            commit;
    end try
    begin catch
        declare @error int, @message varchar(4000), @xstate int;
        select @error = ERROR_NUMBER(), @message = ERROR_MESSAGE(), @xstate = XACT_STATE();
        if @xstate = -1
            rollback;
        if @xstate = 1 and @trancount = 0
            rollback
        if @xstate = 1 and @trancount > 0
            rollback transaction usp_my_procedure_name;

        raiserror ('usp_my_procedure_name: %d: %s', 16, 1, @error, @message) ;
    end catch   
end
go

It allows me to write atomic procedures that rollback only their own work in case of recoverable errors.

One of the main issues Transact-SQL procedures face is data purity: sometimes the parameters received or the data in the tables are just plain wrong, resulting in duplicate key errors, referential constrain errors, check constrain errors and so on and so forth. After all, that's exactly the role of these constrains, if these data purity errors would be impossible and all caught by the business logic, the constrains would be all obsolete (dramatic exaggeration added for effect). If XACT_ABORT is ON then all these errors result in the entire transaction being lost, as opposed to being able to code exception blocks that handle the exception gracefully. A typical example is trying to do an INSERT and reverting to an UPDATE on PK violation.

There's a distinction to me that scp is always encrypted with ssh (secure shell), while rsync isn't necessarily encrypted. More specifically, rsync doesn't perform any encryption by itself; it's still capable of using other mechanisms (ssh for example) to perform encryption.

In addition to security, encryption also has a major impact on your transfer speed, as well as the CPU overhead. (My experience is that rsync can be significantly faster than scp.)

Check out this post for when rsync has encryption on.

One important difference is that both String.split() and Scanner can produce empty strings but StringTokenizer never does it.

For example:

String str = "ab cd  ef";

StringTokenizer st = new StringTokenizer(str, " ");
for (int i = 0; st.hasMoreTokens(); i++) System.out.println("#" + i + ": " + st.nextToken());

String[] split = str.split(" ");
for (int i = 0; i < split.length; i++) System.out.println("#" + i + ": " + split[i]);

Scanner sc = new Scanner(str).useDelimiter(" ");
for (int i = 0; sc.hasNext(); i++) System.out.println("#" + i + ": " + sc.next());

Output:

//StringTokenizer
#0: ab
#1: cd
#2: ef
//String.split()
#0: ab
#1: cd
#2: 
#3: ef
//Scanner
#0: ab
#1: cd
#2: 
#3: ef

This is because the delimiter for String.split() and Scanner.useDelimiter() is not just a string, but a regular expression. We can replace the delimiter " " with " +" in the example above to make them behave like StringTokenizer.

For Windows and Python 3.x, my two cents contribution about renaming the file on download :

1. Install wget module : pip install wget
2. Use wget :

import wget
wget.download('Url', 'C:\\PathToMyDownloadFolder\\NewFileName.extension')

Truely working command line example :

python -c "import wget; wget.download(""https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.17.2.tar.xz"", ""C:\\Users\\TestName.TestExtension"")"

Note : 'C:\\PathToMyDownloadFolder\\NewFileName.extension' is not mandatory. By default, the file is not renamed, and the download folder is your local path.

Stack is a memory allocated by the compiler, when ever we compiles the program, in default compiler allocates some memory from OS ( we can change the settings from compiler settings in your IDE) and OS is the one which give you the memory, its depends on many available memory on the system and many other things, and coming to stack memory is allocate when we declare a variable they copy(ref as formals) those variables are pushed on to stack they follow some naming conventions by default its CDECL in Visual studios ex: infix notation: c=a+b; the stack pushing is done right to left PUSHING, b to stack, operator, a to stack and result of those i,e c to stack. In pre fix notation: =+cab Here all the variables are pushed to stack 1st (right to left)and then the operation are made. This memory allocated by compiler is fixed. So lets assume 1MB of memory is allocated to our application, lets say variables used 700kb of memory(all the local variables are pushed to stack unless they are dynamically allocated) so remaining 324kb memory is allocated to heap. And this stack has less life time, when the scope of the function ends these stacks gets cleared.

Please try this way.

<table border="1">
    <tr>
        <th scope="col">Header</th>
        <th scope="col">Header</th>
        <th colspan="2">Header</th>
    </tr> 
    <tr>
        <td scope="row">&nbsp;</td>
        <td scope="row">&nbsp;</td>
        <td scope="col">Split this one</td>
        <td scope="col">into two columns</td>
    </tr>

db.collection_name.aggregate([
    { '$match'    : { } },
    { '$sort'     : { '_id' : -1 } },
    { '$facet'    : {
        metadata: [ { $count: "total" } ],
        data: [ { $skip: 1 }, { $limit: 10 },{ '$project' : {"_id":0} } ] // add projection here wish you re-shape the docs
    } }
] )

Instead of using two queries to find the total count and skip the matched record.
$facet is the best and optimized way.

1. Match the record
   
2. Find total_count
   
3. skip the record
   
4. And also can reshape data according to our needs in the query.

To do with javascript you could do something like this:

<script type="Text/javascript">
var text = <?= $text_from_db; ?>
</script>

Then you can use whatever you want in your javascript to put the text var into the textbox.

More oin regards to question part 4 How do you e-mail that error to an email address? The error_log function has email destination too. http://php.net/manual/en/function.error-log.php

Agha, here I found an example that shows a usage. Send errors message via email using error_log()

error_log($this->_errorMsg, 1, ADMIN_MAIL, "Content-Type: text/html; charset=utf8\r\nFrom: ".MAIL_ERR_FROM."\r\nTo: ".ADMIN_MAIL);

The first is the original for loop. You initialize a variable, set a terminating condition, and provide a state incrementing/decrementing counter (There are exceptions, but this is the classic)

For that,

for (int i=0;i<myString.length;i++) { 
  System.out.println(myString[i]); 
}

is correct.

For Java 5 an alternative was proposed. Any thing that implements iterable can be supported. This is particularly nice in Collections. For example you can iterate the list like this

List<String> list = ....load up with stuff

for (String string : list) {
  System.out.println(string);
}

instead of

for (int i=0; i<list.size();i++) {
  System.out.println(list.get(i));
}

So it's just an alternative notation really. Any item that implements Iterable (i.e. can return an iterator) can be written that way.

What's happening behind the scenes is somethig like this: (more efficient, but I'm writing it explicitly)

Iterator<String> it = list.iterator();
while (it.hasNext()) {
  String string=it.next();
  System.out.println(string);
}

In the end it's just syntactic sugar, but rather convenient.

in my case i always put these stuffs in a p tag like

<p> name : < input type=text /> </p>

and so on and then applying the css like

p {
  text-align:left;
}

p input {
  float:right;
}

You need to specify the width of the p tag.because the input tags will float all the way right.

This css will also affect the submit button. You need to override the rule for this tag.

$ rsync --version
  rsync  version 3.1.3  protocol version 31
  ...

Syntax: rsync <file_/_folder_list> <source> <target>

Folder names (here, WITH a trailing /; e.g. Cancer - Evolution/) are in a folder list file (e.g.: cm_folder_list_test):

# /mnt/Vancouver/projects/ie/claws/data/cm_folder_list_test
# test file: 2019-04-24
Cancer/
Cancer - Evolution/
Cancer - Genomic Variants/
Cancer - Metastasis (EMT Transition ...)/
Cancer Pathways, Networks/
Catabolism - Autophagy; Phagosomes; Mitophagy/
Catabolism - Lysosomes/

If you don't include those trailing /, the rsync'd target folders are created, but are empty.

Those folder names are appended to the rest of their path (/home/victoria/Mail/2_RESEARCH - NEWS), thus providing the complete folder path to rsync; e.g.: /home/victoria/Mail/2_RESEARCH - NEWS/Cancer - Evolution/.

Note that you also need to use --files-from= ..., NOT --include-from= ...

rsync -aqP --delete --files-from=/mnt/Vancouver/projects/ie/claws/data/cm_folder_list_test "/home/victoria/Mail/2_RESEARCH - NEWS" $IN/

(In my BASH script, I defined variable $IN as follows.)

BASEDIR="/mnt/Vancouver/projects/ie/claws"
IN=$BASEDIR/data/test/input

rsync options used:

 -a  :   archive: equals -rlptgoD (no -H,-A,-X)
    -r  :   recursive
    -l  :   copy symlinks as symlinks
    -p  :   preserve permissions
    -t  :   preserve modification times 
    -g  :   preserve group 
    -o  :   preserve owner (super-user only) 
    -D  :   same as --devices --specials 
  -q  :   quiet (https://serverfault.com/questions/547106/run-totally-silent-rsync)

  --delete
    This  tells  rsync to delete extraneous files from the RECEIVING SIDE (ones
    that AREN’T ON THE SENDING SIDE), but only for the directories that are
    being synchronized.  You must have asked rsync to send the whole directory
    (e.g.  "dir" or "dir/") without using a wildcard for the directory’s contents
    (e.g. "dir/*") since the wildcard is expanded by the shell and rsync thus
    gets a request to transfer individual files, not the files’ parent directory.
    Files  that  are  excluded  from  the transfer are also excluded from being
    deleted unless you use the --delete-excluded option or mark the rules as
    only matching on the sending side (see the include/exclude modifiers in the
    FILTER RULES section).  ...

It's really easy to do: reliable and not messy:

        Try
            Clients.Client.Send(BufferByte)
        Catch verror As Exception
            BufferString = verror.ToString
        End Try
        If BufferString <> "" Then
            EventLog.Text &= "User disconnected: " + vbNewLine
            Clients.Close()
        End If

SWIFT 4.x :

self.mConstraint.constant = 100.0
UIView.animate(withDuration: 0.3) {
        self.view.layoutIfNeeded()

Example with completion:

self.mConstraint.constant = 100
UIView.animate(withDuration: 0.3, animations: {
        self.view.layoutIfNeeded()
    }, completion: {res in
        //Do something

A list comprehension seems to be a good way to do this:

Just to warn, that in case of a deque container, all solutions that check for the deque iterator equality to numbers.end() will likely fail on gcc 4.8.4. Namely, erasing an element of the deque generally invalidates pointer to numbers.end():

#include <iostream>
#include <deque>

using namespace std;
int main() 
{

  deque<int> numbers;

  numbers.push_back(0);
  numbers.push_back(1);
  numbers.push_back(2);
  numbers.push_back(3);
  //numbers.push_back(4);

  deque<int>::iterator  it_end = numbers.end();

  for (deque<int>::iterator it = numbers.begin(); it != numbers.end(); ) {
    if (*it % 2 == 0) {
      cout << "Erasing element: " << *it << "\n";
      numbers.erase(it++);
      if (it_end == numbers.end()) {
    cout << "it_end is still pointing to numbers.end()\n";
      } else {
    cout << "it_end is not anymore pointing to numbers.end()\n";
      }
    }
    else {
      cout << "Skipping element: " << *it << "\n";
      ++it;
    }
  }
}

Output:

Erasing element: 0
it_end is still pointing to numbers.end()
Skipping element: 1
Erasing element: 2
it_end is not anymore pointing to numbers.end()

Note that while the deque transformation is correct in this particular case, the end pointer has been invalidated along the way. With the deque of a different size the error is more apparent:

int main() 
{

  deque<int> numbers;

  numbers.push_back(0);
  numbers.push_back(1);
  numbers.push_back(2);
  numbers.push_back(3);
  numbers.push_back(4);

  deque<int>::iterator  it_end = numbers.end();

  for (deque<int>::iterator it = numbers.begin(); it != numbers.end(); ) {
    if (*it % 2 == 0) {
      cout << "Erasing element: " << *it << "\n";
      numbers.erase(it++);
      if (it_end == numbers.end()) {
    cout << "it_end is still pointing to numbers.end()\n";
      } else {
    cout << "it_end is not anymore pointing to numbers.end()\n";
      }
    }
    else {
      cout << "Skipping element: " << *it << "\n";
      ++it;
    }
  }
}

Output:

Erasing element: 0
it_end is still pointing to numbers.end()
Skipping element: 1
Erasing element: 2
it_end is still pointing to numbers.end()
Skipping element: 3
Erasing element: 4
it_end is not anymore pointing to numbers.end()
Erasing element: 0
it_end is not anymore pointing to numbers.end()
Erasing element: 0
it_end is not anymore pointing to numbers.end()

Segmentation fault (core dumped)

Here is one of the ways to fix this:

#include <iostream>
#include <deque>

using namespace std;
int main() 
{

  deque<int> numbers;
  bool done_iterating = false;

  numbers.push_back(0);
  numbers.push_back(1);

    done_iterating = true;
      } 
      if (*it % 2 == 0) {
    cout << "Erasing element: " << *it << "\n";
      numbers.erase(it++);

Use format method with a specific pattern to extract the time. Working example

An improved version of P i's solution, a category on NSString, that not only will tell, if a string is found within another string, but also takes a range by reference, is:

@interface NSString (Contains)
-(BOOL)containsString: (NSString*)substring
              atRange:(NSRange*)range;

-(BOOL)containsString:(NSString *)substring;
@end

@implementation NSString (Contains)

-(BOOL)containsString:(NSString *)substring
              atRange:(NSRange *)range{

    NSRange r = [self rangeOfString : substring];
    BOOL found = ( r.location != NSNotFound );
    if (range != NULL) *range = r;
    return found;
}

-(BOOL)containsString:(NSString *)substring
{
    return [self containsString:substring
                        atRange:NULL];
}

@end

Use it like:

NSString *string = @"Hello, World!";

//If you only want to ensure a string contains a certain substring
if ([string containsString:@"ello" atRange:NULL]) {
    NSLog(@"YES");
}

// Or simply
if ([string containsString:@"ello"]) {
    NSLog(@"YES");
}

//If you also want to know substring's range
NSRange range;
if ([string containsString:@"ello" atRange:&range]) {
    NSLog(@"%@", NSStringFromRange(range));
}

Use the JSON.stringify() method:

const stringified = JSON.stringify({})  // pass object you want to convert in string format

// iterate over the map
for(Entry<String, ArrayList<String>> entry : test1.entrySet()){
    // iterate over each entry
    for(String item : entry.getValue()){
        // print the map's key with each value in the ArrayList
        System.out.println(entry.getKey() + ": " + item);
    }
}

Because it has already been pushed, you shouldn't directly manipulate history. git revert will revert specific changes from a commit using a new commit, so as to not manipulate commit history.

To know the react version, Open package.json file in root folder, search the keywork react. You will see like "react": "^16.4.0",

I ran into an article that illustrates a method where the data from the same excel sheet can be imported in the selected table until there is no modifications in excel with data types.

If the data is inserted or overwritten with new ones, importing process will be successfully accomplished, and the data will be added to the table in SQL database.

The article may be found here: http://www.sqlshack.com/using-ssis-packages-import-ms-excel-data-database/

Hope it helps.

There is a simple way to read from the console.

Please find the below code:

import java.util.Scanner;

    public class ScannerDemo {

        public static void main(String[] args) {
            Scanner sc = new Scanner(System.in);

            // Reading of Integer
            int number = sc.nextInt();

            // Reading of String
            String str = sc.next();
        }
    }

For a detailed understanding, please refer to the below documents.

Doc

Now let's talk about the detailed understanding of the Scanner class working:

public Scanner(InputStream source) {
    this(new InputStreamReader(source), WHITESPACE_PATTERN);
}

This is the constructor for creating the Scanner instance.

Here we are passing the InputStream reference which is nothing but a System.In. Here it opens the InputStream Pipe for console input.

public InputStreamReader(InputStream in) {
    super(in);
    try {
        sd = StreamDecoder.forInputStreamReader(in, this, (String)null); // ## Check lock object
    }
    catch (UnsupportedEncodingException e) {
        // The default encoding should always be available
        throw new Error(e);
    }
}

By passing the System.in this code will opens the socket for reading from console.

If you want just to test a cross domain application in which the browser blocks your request, then you can just open your browser in unsafe mode and test your application without changing your code and without making your code unsafe. From MAC OS you can do this from the terminal line:

open -a Google\ Chrome --args --disable-web-security --user-data-dir

@Adam: I think in your code snippet you should track the start position for m.find() because string replacement may change the offset after the last character matched.

public static void replaceAll(StringBuilder sb, Pattern pattern, String replacement) {
    Matcher m = pattern.matcher(sb);
    int start = 0;
    while (m.find(start)) {
        sb.replace(m.start(), m.end(), replacement);
        start = m.start() + replacement.length();
    }
}

This worked for me:

BufferedImage bufImgs = ImageIO.read(new File("c:\\adi.bmp"));    
double[][] data = new double[][];
bufImgs.getData().getPixels(0,0,bufImgs.getWidth(),bufImgs.getHeight(),data[i]);    

pretty sure you just want the plain old replace function. use like this:

myString.replace('username1','');

i suppose if you want to remove the trailing comma do this instead:

myString.replace('username1,','');

edit:

here is your site specific code:

jQuery("#post_like_list-510").text().replace(...) 

I think it will be easy to you. I am using group_concat which concatenate diffent values with separator as we have defined

select ID,User, GROUP_CONCAT(Distinct Department order  by Department asc 

separator ', ') as Department from Table_Name   group by ID

Another alternative is pushd, which will automatically switch drives as needed. It also allows you to return to the previous directory via popd:

C:\Temp>pushd D:\some\folder

D:\some\folder>popd

C:\Temp>_

I see what you are trying to do, you are trying to use the <body> tag as the container for the main content of the page. Instead, use the <main> tag, as specified in the HTML5 spec. I use this layout:

    <!DOCTYPE html>
    <html>
        <head> *Metadata* </head>
        <body>
            <header>
                *<h1> and other important stuff </h1>*
                <nav> *Usually a formatted <Ul>* </nav>
            </header>
            <main> *All my content* </main>
            <footer> *Copyright, links, social media etc* </footer>
        </body>
    </html>

I'm not 100% sure but I think that anything outside the <body> tag is considered metadata and will not be rendered by the browser. I don't think that the DOM can access it either.

To conclude, use the <main> tag for your content and keep formatting your HTML the correct way as you have in your first code snippet. You used the <section> tag but I think that comes with some weird formatting issues when you try to apply CSS.

I would suggest that you use a timer, but set it to check every 45 seconds, not minute. Otherwise you can run into situations where with heavy load, the check for a particular minute is missed, because between the time the timer triggers and the time your code runs and checks the current time, you might have missed the target minute.

On Unix you can use valgrind to find issues. It's free and powerful. If you'd rather do it yourself you can overload the new and delete operators to set up a configuration where you have 1 byte with 0xDEADBEEF before and after each new object. Then track what happens at each iteration. This can fail to catch everything (you aren't guaranteed to even touch those bytes) but it has worked for me in the past on a Windows platform.

I have used _itoa(...) on RedHat 6 and GCC compiler. It works.

Just a little modification to @Epsicron 's answer

SELECT SUBSTRING(string, PATINDEX('%[0-9]%', string), PATINDEX('%[0-9][^0-9]%', string + 't') - PATINDEX('%[0-9]%', 
                    string) + 1) AS Number

no need for a temporary variable

&& and || take scalar inputs and short-circuit always. | and & take array inputs and short-circuit only in if/while statements. For assignment, the latter do not short-circuit.

See these doc pages for more information.

Another (maybe faster for large directories) approach:

$ find dir1 | sed 's,^[^/]*/,,' | sort > dir1.txt && find dir2 | sed 's,^[^/]*/,,' | sort > dir2.txt
$ diff dir1.txt dir2.txt

The sed command removes the first directory component thanks to Erik`s post)

Write a Boolean function that checks the regex and use apply on the column

foo[foo['b'].apply(regex_function)]

We tried a few applications, both trials of commercial products and freely available ones. Ultimately, it was the trial edition of the Team Test Load Agent software that we tried. It definitely works great and is fairly simple to use. In the long run, it bolstered our argument to move to Team Foundation Server and equip all parts of the department with the appropriate tooling.

The obvious downside, however, is the price.

If you want to pass the form to the controller for validation purposes you can simply pass it as an argument to the method handling the submission. Use the form name, so for the original question it would be something like:

<button ng-click="submit(customerForm)">Save</button>

I know people say you shouldn't use regular expressions to parse HTML, but in this case I find it perfectly fine.

$string = '<img border="0" src="/images/image.jpg" alt="Image" width="100" height="100" />';
preg_match('/<img(.*)src(.*)=(.*)"(.*)"/U', $string, $result);
$foo = array_pop($result);

mongorestore -d db_name /path/

make sure you run this query in bin folder of mongoDb

C:\Program Files\MongoDB\Server\4.2\bin -

then run this above command.

FOR Eclipse/NetBeans

Restart your IDE and run your code again this is only trick work for me after one hour long struggle.

Here is my code:

File file = new File("file-path");
if(file.exists()){
  if(file.delete()){
     System.out.println("Delete");
  }
  else{

       System.out.println("not delete");
  }
}

Output:

Delete

int arr[5] = {4, 1, 3, 2, 6};
vector<int> vec;
int i =0;
int no_to_be_found;

cin >> no_to_be_found;

while(i != 4)
{
    vec.push_back(arr[i]);
    i++;
}

cout << find(vec.begin(),vec.end(),no_to_be_found) - vec.begin();

You shouldn't change the npm registry using .bat files. Instead try to use modify the .npmrc file which is the configuration for npm. The correct command for changing registry is

npm config set registry <registry url>

you can find more information with npm help config command, also check for privileges when and if you are running .bat files this way.

If you sometimes run different versions of your application, make sure you delete 'Bla' from the application bin directory if the version running doesn't need it.

Before creating a new branch always the best practice is to have the latest of repo in your local machine. Follow these steps for error free branch creation.

 1. $ git branch (check which branches exist and which one is currently active (prefixed with *). This helps you avoid creating duplicate/confusing branch name)
 2. $ git branch <new_branch> (creates new branch)
 3. $ git checkout new_branch
 4. $ git add . (After making changes in the current branch)
 5. $ git commit -m "type commit msg here"
 6. $ git checkout master (switch to master branch so that merging with new_branch can be done)
 7. $ git merge new_branch (starts merging)
 8. $ git push origin master (push to the remote server)

I referred this blog and I found it to be a cleaner approach.

Just a supplement here.

The following question is that what if I want more subplots in the figure?

As mentioned in the Doc, we can use fig = plt.subplots(nrows=2, ncols=2) to set a group of subplots with grid(2,2) in one figure object.

Then as we know, the fig, ax = plt.subplots() returns a tuple, let's try fig, ax1, ax2, ax3, ax4 = plt.subplots(nrows=2, ncols=2) firstly.

ValueError: not enough values to unpack (expected 4, got 2)

It raises a error, but no worry, because we now see that plt.subplots() actually returns a tuple with two elements. The 1st one must be a figure object, and the other one should be a group of subplots objects.

So let's try this again:

fig, [[ax1, ax2], [ax3, ax4]] = plt.subplots(nrows=2, ncols=2)

and check the type:

type(fig) #<class 'matplotlib.figure.Figure'>
type(ax1) #<class 'matplotlib.axes._subplots.AxesSubplot'>

Of course, if you use parameters as (nrows=1, ncols=4), then the format should be:

fig, [ax1, ax2, ax3, ax4] = plt.subplots(nrows=1, ncols=4)

So just remember to keep the construction of the list as the same as the subplots grid we set in the figure.

Hope this would be helpful for you.

I would use the following function. I don't like sprintf; it doesn't do what I want!!

#define hexchar(x)    ((((x)&0x0F)>9)?((x)+'A'-10):((x)+'0'))
typedef signed long long   Int64;

// Special printf for numbers only
// See formatting information below.
//
//    Print the number "n" in the given "base"
//    using exactly "numDigits".
//    Print +/- if signed flag "isSigned" is TRUE.
//    Use the character specified in "padchar" to pad extra characters.
//
//    Examples:
//    sprintfNum(pszBuffer, 6, 10, 6,  TRUE, ' ',   1234);  -->  " +1234"
//    sprintfNum(pszBuffer, 6, 10, 6, FALSE, '0',   1234);  -->  "001234"
//    sprintfNum(pszBuffer, 6, 16, 6, FALSE, '.', 0x5AA5);  -->  "..5AA5"
void sprintfNum(char *pszBuffer, int size, char base, char numDigits, char isSigned, char padchar, Int64 n)
{
    char *ptr = pszBuffer;

    if (!pszBuffer)
    {
        return;
    }

    char *p, buf[32];
    unsigned long long x;
    unsigned char count;

    // Prepare negative number
    if (isSigned && (n < 0))
    {
        x = -n;
    }
    else
    {
        x = n;
    }

    // Set up small string buffer
    count = (numDigits-1) - (isSigned?1:0);
    p = buf + sizeof (buf);
    *--p = '\0';

    // Force calculation of first digit
    // (to prevent zero from not printing at all!!!)
    *--p = (char)hexchar(x%base);
    x = x / base;

    // Calculate remaining digits
    while(count--)
    {
        if(x != 0)
        {
            // Calculate next digit
            *--p = (char)hexchar(x%base);
            x /= base;
        }
        else
        {
            // No more digits left, pad out to desired length
            *--p = padchar;
        }
    }

    // Apply signed notation if requested
    if (isSigned)
    {
        if (n < 0)
        {
            *--p = '-';
        }
        else if (n > 0)
        {
            *--p = '+';
        }
        else
        {
            *--p = ' ';
        }
    }

    // Print the string right-justified
    count = numDigits;
    while (count--)
    {
        *ptr++ = *p++;
    }
    return;
}

I had multiple versions of the gcc compiler installed and needed to use a more recent version than the default installation. Since I am not a system administrator for our Linux systems, I cannot just change /usr/lib or many of the other suggestions above. I was encountering this problem and eventually tracked it down to setting my path to the 32-bit library directory instead of the 64-bit library (lib64) directory. Since the libraries in the 32-bit directory were incompatible, the system defaulted to the older version which was out of date.

Using -L to the path I was referencing gave warnings about "skipping incompatible libstdc++.so when searching for -lstdc++". This was the hint that helped me finally resolve the problem.

To answer your question you can use ES6 features,

var var=10;
console.log(`var=${var}`);

It turns out that OpenSSL is compiled and enabled in php 5.3 of XAMPP 1.7.2 and so no longer requires a separate extension dll.

However, you STILL need to enable it in your PHP.ini file the line extension=php_openssl.dll

As people say, JavaScript will convert a string of number to integer, so it is not possible to use directly on an associative array, but objects will work for you in similar way I think.

You can create your object:

var object = {};

And add the values as array works:

object[1] = value;
object[2] = value;

This will give you:

{
  '1': value,
  '2': value
}

After that you can access it like an array in other languages getting the key:

for(key in object)
{
   value = object[key] ;
}

I have tested and works.

also using http://php.net/error_get_last will not help you out, because mail() does not emmit its errors into this function.

Only way seems to be using a proper mailer, like already suggested above.

You can use the CSS3 Linear Gradient property along with your background-image like this:

#landing-wrapper {
    display:table;
    width:100%;
    background: linear-gradient( rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5) ), url('landingpagepic.jpg');
    background-position:center top;
    height:350px;
}

Here's a demo:

#landing-wrapper {_x000D_
  display: table;_x000D_
  width: 100%;_x000D_
  background: linear-gradient(rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5)), url('http://placehold.it/350x150');_x000D_
  background-position: center top;_x000D_
  height: 350px;_x000D_
  color: white;_x000D_
}

<div id="landing-wrapper">Lorem ipsum dolor ismet.</div>

Receive POST and GET request in nodejs :

1).Server

    var http = require('http');
    var server = http.createServer ( function(request,response){

    response.writeHead(200,{"Content-Type":"text\plain"});
    if(request.method == "GET")
        {
            response.end("received GET request.")
        }
    else if(request.method == "POST")
        {
            response.end("received POST request.");
        }
    else
        {
            response.end("Undefined request .");
        }
});

server.listen(8000);
console.log("Server running on port 8000");

2). Client :

var http = require('http');

var option = {
    hostname : "localhost" ,
    port : 8000 ,
    method : "POST",
    path : "/"
} 

    var request = http.request(option , function(resp){
       resp.on("data",function(chunck){
           console.log(chunck.toString());
       }) 
    })
    request.end();

This worked for me:

cp <path_to>/libstdc++.so.6 $PWD
./<executable>

This tidbit came from @kerin (comment provided above):

you might check out http://stackoverflow.com/questions/13636513/linking-libstdc-statically-any-gotchas

From that link:

If you put the newer libstdc++.so in the same directory as the executable it will be found at run-time, problem solved.

The error I was getting mentioned that libstdc++.so.6 was coming from /usr/lib64/, but this is not the library I linked against! The message looked like:

<executing_binary>: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by <executing_binary>)

I did verify that LD_LIBRARY_PATH had the directory (and that it was the first path). For some reason at runtime it was still looking at /usr/lib64/libstdc++.so.6.

I took the advice from the article above and copied the libstdc++.so.6 from where I linked into the directory with my executable, ran from there, and it worked!

Just put the commands you want to run into a file, then pass it to the shell along with the database name and redirect the output to a file. So, if your find command is in find.js and your database is foo, it would look like this:

./mongo foo find.js >> out.json

This is what worked for me:

https://developer.apple.com/library//ios/documentation/UIKit/Reference/UIViewController_Class/index.html#//apple_ref/occ/clm/UIViewController/attemptRotationToDeviceOrientation

Call it in your viewDidAppear: method.

- (void) viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];

    [UIViewController attemptRotationToDeviceOrientation];
}

I installed and deinstalled ajdt-plugin and got the same problem.

The best workaround for reading CSV files with UTF-8 on Mac is to convert them into XLSX format. I have found a script made by Konrad Foerstner, which I have improved little bit by adding support for different delimiter characters.

Download the script from Github https://github.com/brablc/clit/blob/master/csv2xlsx.py. In order to run it you will need to install a python module openpyxl for Excel file manipulation: sudo easy_install openpyxl.

The java.util.Date class in Java represents a particular moment in time (e,.g., 2013 Nov 25 16:30:45 down to milliseconds), but the DATE data type in the DB represents a date only (e.g., 2013 Nov 25). To prevent you from providing a java.util.Date object to the DB by mistake, Java doesn’t allow you to set a SQL parameter to java.util.Date directly:

PreparedStatement st = ...
java.util.Date d = ...
st.setDate(1, d); //will not work

But it still allows you to do that by force/intention (then hours and minutes will be ignored by the DB driver). This is done with the java.sql.Date class:

PreparedStatement st = ...
java.util.Date d = ...
st.setDate(1, new java.sql.Date(d.getTime())); //will work

A java.sql.Date object can store a moment in time (so that it’s easy to construct from a java.util.Date) but will throw an exception if you try to ask it for the hours (to enforce its concept of being a date only). The DB driver is expected to recognize this class and just use 0 for the hours. Try this:

public static void main(String[] args) {
  java.util.Date d1 = new java.util.Date(12345);//ms since 1970 Jan 1 midnight
  java.sql.Date d2 = new java.sql.Date(12345);
  System.out.println(d1.getHours());
  System.out.println(d2.getHours());
}

<select id="mycontrolId" multiple="multiple">
   <option value="1" >one</option>
   <option value="2" >two</option>
   <option value="3">three</option>
   <option value="4">four</option>
</select>

var data = "1,3,4"; var dataarray = data.split(",");

$("#mycontrolId").val(dataarray);

Bootstrap have a specific class for this: center-block

<button type="button" class="your_class center-block"> Book </button>

Try just importing the functions needed from main.py? So,

from main import SomeFunction

It could be that you've named a function in batch.py the same as one in main.py, and when you import main.py the program runs the main.py function instead of the batch.py function; doing the above should fix that. I hope.

Check this one. It will work.

i believe what you're looking for is the str.encode("string-escape") function. For example, if you have a variable that you want to 'raw string':

a = '\x89'
a.encode('unicode_escape')
'\\x89'

Note: Use string-escape for python 2.x and older versions

I was searching for a similar solution and found the solution via: casting raw strings python

For Query parameters like domain.com/test?format=json&type=mini format, then you can easily receive it via - req.query.

app.get('/test', function(req, res){
  var format = req.query.format,
      type = req.query.type;
});

self.view.backgroundColor = UIColor.redColor()

In Swift 3:

self.view.backgroundColor = UIColor.red

This is a late answer but if anyone reading this question is using razor, what you should remember is that razor encodes everything by default, but by using MvcHtmlString in your html helpers you can tell razor that it doesn't need to encode it.

If you want razor to not encode a string use

@Html.Raw("<span>hi</span>")

Decompiling Raw(), shows us that it's wrapping the string in a HtmlString

public IHtmlString Raw(string value) {
    return new HtmlString(value); 
}

"HtmlString only exists in ASP.NET 4.

MvcHtmlString was a compatibility shim added to MVC 2 to support both .NET 3.5 and .NET 4. Now that MVC 3 is .NET 4 only, it's a fairly trivial subclass of HtmlString presumably for MVC 2->3 for source compatibility." source

Make sure your app is configured to use the appropriate URL & domain of your site. That may be it.

Answering this question in the content that the questioners intent was to use the solution for software licensing, the requirements are:

1. No 3rd party can produce a license key from decompiling the app
2. The content of the software key does not need to be secure
3. Software key is not human readable

A Digital Signature will solve this issue as the raw data that makes the key can be signed with a private key which makes it not human readable but could be decoded if reverse engineered. But the private key is safe which means no one will be able to make licenses for your software (which is the point).

Remember you can not prevent a skilled person from removing the software locks on your product. So if they have to hack each version that is released. But you really don't want them to be able to generate new keys for your product that can be shared for all versions.

Python The PyNaCl documentation has an example of 'Digital Signature' which will suite the purpose. http://pynacl.readthedocs.org/en/latest/signing/

and of cause NaCl project to C examples

Alright, here's the best solution I've found that meets all the requirements:

1. Download the Sublime-Text-Advanced-CSV Sublime plugin and install.
2. Specify a delimiter for your column (default is ","), via the "CSV: Set Delimiter" command.
3. Hit "ctrl + , s" (or select from Command Palette) and your column will be selected.

No need for mouse interaction whatsoever.

if you got troubles with windows cmd command and .bat just escape percents like that

git show -s --format=%%ct

The % character has a special meaning for command line parameters and FOR parameters. To treat a percent as a regular character, double it: %%

Syntax : Escape Characters, Delimiters and Quotes

not a one-line-code solution, but pretty easy:

sub-class Activity, then override and add finish() to onPause() method

this way, activity will be gone once it enters background, therefore the app won't keep a stack of activities, you can finish() the current activity and the app is gone!

Here's what worked for me:

#div {
  display: flex;
  justify-content: center;
}

#table {
  align-self: center;
}

And this aligned it vertically and horizontally.

Obviously there are a number of possible causes and the previous answers document them well, but here's how I solved this for in one particular case:

A student of mine had this problem and I nearly tore my hair out trying to figure it out. It turned out that the file didn't exist, even though it looked like it did. The problem was that Windows 7 was configured to "Hide file extensions for known file types." This means that if file appears to have the name "data.txt" its actual filename is "data.txt.txt".

Hope this helps others save themselves some hair.

I prefer something like the following:

type StringRef []byte

func (s StringRef) String() string {
        return string(s[:])
}

…

// rather silly example, but ...
fmt.Printf("foo=%s\n",StringRef("bar"))

The Easiest Way

If you have the unix epoch in milliseconds, in my case - 1601209912824

1. convert it into a Date Object as so

const dateObject = new Date(milliseconds)
const humanDateFormat = dateObject.toString() 

output -

Sun Sep 27 2020 18:01:52 GMT+0530 (India Standard Time)

2. if you want the date in UTC -

const dateObject = new Date(milliseconds)
const humanDateFormat = dateObject.toUTCString() 

3. Now you can format it as you please.

The rest are almost correct, except they should order by Date DESC

SELECT DISTINCT(Date) AS Date FROM buy ORDER BY Date DESC;

In JavaScript, the type of the value solely controls whether that value will be assigned by value-copy or by reference-copy.

Primitive values are always assigned/passed by value-copy:

• null
• undefined
• string
• number
• boolean
• symbol in ES6

Compound values are always assigned/passed by reference-copy

• objects
• arrays
• function

For example

var a = 2;
var b = a; // `b` is always a copy of the value in `a`
b++;
a; // 2
b; // 3

var c = [1,2,3];
var d = c; // `d` is a reference to the shared `[1,2,3]` value
d.push( 4 );
c; // [1,2,3,4]
d; // [1,2,3,4]

In the above snippet, because 2 is a scalar primitive, a holds one initial copy of that value, and b is assigned another copy of the value. When changing b, you are in no way changing the value in a.

But both c and d are separate references to the same shared value [1,2,3], which is a compound value. It's important to note that neither c nor d more "owns" the [1,2,3] value -- both are just equal peer references to the value. So, when using either reference to modify (.push(4)) the actual shared array value itself, it's affecting just the one shared value, and both references will reference the newly modified value [1,2,3,4].

var a = [1,2,3];
var b = a;
a; // [1,2,3]
b; // [1,2,3]

// later
b = [4,5,6];
a; // [1,2,3]
b; // [4,5,6]

When we make the assignment b = [4,5,6], we are doing absolutely nothing to affect where a is still referencing ([1,2,3]). To do that, b would have to be a pointer to a rather than a reference to the array -- but no such capability exists in JS!

function foo(x) {
    x.push( 4 );
    x; // [1,2,3,4]

    // later
    x = [4,5,6];
    x.push( 7 );
    x; // [4,5,6,7]
}

var a = [1,2,3];

foo( a );

a; // [1,2,3,4]  not  [4,5,6,7]

When we pass in the argument a, it assigns a copy of the a reference to x. x and a are separate references pointing at the same [1,2,3] value. Now, inside the function, we can use that reference to mutate the value itself (push(4)). But when we make the assignment x = [4,5,6], this is in no way affecting where the initial reference a is pointing -- still points at the (now modified) [1,2,3,4] value.

To effectively pass a compound value (like an array) by value-copy, you need to manually make a copy of it, so that the reference passed doesn't still point to the original. For example:

foo( a.slice() );

Compound value (object, array, etc) that can be passed by reference-copy

function foo(wrapper) {
    wrapper.a = 42;
}

var obj = {
    a: 2
};

foo( obj );

obj.a; // 42

Here, obj acts as a wrapper for the scalar primitive property a. When passed to foo(..), a copy of the obj reference is passed in and set to the wrapperparameter. We now can use the wrapper reference to access the shared object, and update its property. After the function finishes, obj.a will see the updated value 42.

Source

Okay so what helped me was iterating backwards. I was trying to remove an entry from a list but iterating upwards and it screwed up the loop because the entry didn't exist anymore:

for (int x = myList.Count - 1; x > -1; x--)
{
    myList.RemoveAt(x);
}

Try this:

this.getSupportActionBar().hide();

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

    try
    {
        this.getSupportActionBar().hide();
    }
    catch (NullPointerException e){}

    setContentView(R.layout.activity_main);
}

Here is a table of the different events and the levels of browser support. You need to pick an event which is supported across at least all modern browsers.

As you will see from the table, the keypress and change event do not have uniform support whereas the keyup event does.

Also make sure you attach the event handler using a cross-browser-compatible method...

Also, mod can be used like this:

int a = 7;
b = a % 2;

b would equal 1. Because 7 % 2 = 1.

 //working code from laravel 5.2

 public function store(Request $request)
 {
          $file = $request->file('file');
            if($file)
            {
                    $extension =  $file->clientExtension();
            }
            echo $extension;
 }

Is is not the same as = -- Is compares the references, whilst = will compare the values.

If you're using v2 of the .Net Framework (or later), there is the IsNot operator which will do the right thing, and read more naturally.

@vnr you can retrieve all the sort keys associated with a partition key by just using the query using partion key. No need of scan. The point here is partition key is compulsory in a query . Sort key are used only to get range of data

The CSS3 keyword initial sets the CSS3 property to the initial value as defined in the spec. The initial keyword has broad browser support except for the IE and Opera Mini families.

Since IE's lack of support may cause issue here are some of the ways you can reset some CSS properties to their initial values:

As mentioned in a comment by @user566245 :

this is correct in principle, but individual mileage may vary. For example certain elements like textarea by default have a border, applying this reset will render those textarea's border less.

JAVASCRIPT ?

Nobody thought about other than css to reset css? Yes?

There is that snip fully relevant : https://stackoverflow.com/a/14791113/845310

getElementsByTagName("*") will return all elements from DOM. Then you may set styles for each element in the collection:

answered Feb 9 '13 at 20:15 by VisioN

var allElements = document.getElementsByTagName("*");
for (var i = 0, len = allElements.length; i < len; i++) {
    var element = allElements[i];
    // element.style.border = ...
}

With all this said; i don't think a css reset is something feasable unless we end up with only one web browser .. if the 'default' is set by browser in the end.

With System.Text.Json and .NET Core 3.0 this worked for me:

var jsonSerializerOptions = new JsonSerializerOptions()
{
    IgnoreNullValues = true
};
var myJson = JsonSerializer.Serialize(myObject, jsonSerializerOptions );

As per my understanding sys.stdout.flush() pushes out all the data that has been buffered to that point to a file object. While using stdout, data is stored in buffer memory (for some time or until the memory gets filled) before it gets written to terminal. Using flush() forces to empty the buffer and write to terminal even before buffer has empty space.

It's the part of the .NET Framework that isn't contained within the Client Profile. See MSDN for more info; specifically:

The .NET Framework is made up of the .NET Framework 4 Client Profile and .NET Framework 4 Extended components that exist separately in Programs and Features.

try: window.document......

var body = window.document.getElementsByTagName("body")[0];

Try using rextract. It will let you extract text using a regular expression and reformat it.

Example:

$ echo "This is 02G05 a test string 20-Jul-2012" | ./rextract '([\d]+G[\d]+)' '${1}'

2G05

Besides the for-loop based solutions, you can also use an ostream_iterator<>. Here's an example that leverages the sample code in the (now retired) SGI STL reference:

#include <iostream>
#include <iterator>
#include <algorithm>

int main()
{
  short foo[] = { 1, 3, 5, 7 };

  using namespace std;
  copy(foo,
       foo + sizeof(foo) / sizeof(foo[0]),
       ostream_iterator<short>(cout, "\n"));
}

This generates the following:

 ./a.out 
1
3
5
7

However, this may be overkill for your needs. A straight for-loop is probably all that you need, although litb's template sugar is quite nice, too.

Edit: Forgot the "printing in reverse" requirement. Here's one way to do it:

#include <iostream>
#include <iterator>
#include <algorithm>

int main()
{
  short foo[] = { 1, 3, 5, 7 };

  using namespace std;

  reverse_iterator<short *> begin(foo + sizeof(foo) / sizeof(foo[0]));
  reverse_iterator<short *> end(foo);

  copy(begin,
       end,
       ostream_iterator<short>(cout, "\n"));
}

and the output:

$ ./a.out 
7
5
3
1

Edit: C++14 update that simplifies the above code snippets using array iterator functions like std::begin() and std::rbegin():

#include <iostream>
#include <iterator>
#include <algorithm>

int main()
{
    short foo[] = { 1, 3, 5, 7 };

    // Generate array iterators using C++14 std::{r}begin()
    // and std::{r}end().

    // Forward
    std::copy(std::begin(foo),
              std::end(foo),
              std::ostream_iterator<short>(std::cout, "\n"));

    // Reverse
    std::copy(std::rbegin(foo),
              std::rend(foo),
              std::ostream_iterator<short>(std::cout, "\n"));
}

This function trims a string from left and right. Also it removes carriage returns from the string, an action which is not done by the LTRIM and RTRIM

IF OBJECT_ID(N'dbo.TRIM', N'FN') IS NOT NULL
    DROP FUNCTION dbo.TRIM;
GO
CREATE FUNCTION dbo.TRIM (@STR NVARCHAR(MAX)) RETURNS NVARCHAR(MAX)
BEGIN
    RETURN(LTRIM(RTRIM(REPLACE(REPLACE(@STR ,CHAR(10),''),CHAR(13),''))))
END;
GO

On Mac gcc is installed by default in /usr/local/bin

To run C:

gcc -o tutor tutor.c 

you need to convert to char first because converting to int adds those days to 1900-01-01

select CONVERT (datetime,convert(char(8),rnwl_efctv_dt ))

here are some examples

select CONVERT (datetime,5)

1900-01-06 00:00:00.000

select CONVERT (datetime,20100101)

blows up, because you can't add 20100101 days to 1900-01-01..you go above the limit

convert to char first

declare @i int
select @i = 20100101
select CONVERT (datetime,convert(char(8),@i))

//Javascript file 1

localStorage.setItem('Data',10);

//Javascript file 2

var number=localStorage.getItem('Data');

Don't forget to link your JS files in html :)

To use support libraries starting from version 26.0.0 you need to add Google's Maven repository to your project's build.gradle file as described here: https://developer.android.com/topic/libraries/support-library/setup.html

allprojects {
        repositories {
            jcenter()
            maven {
                url "https://maven.google.com"
            }
        }
    }

For Android Studio 3.0.0 and above:

allprojects {
        repositories {
            jcenter()
            google()
        }
    }

Just add C:\OpenCV2.0\bin into your PATH environment variable

or

When you install OpenCV,

Choose the option, Add OpenCV to the system PATH for current user which is not default one

Why can't you do it? Because the language doesn't allow you to initializa a base class' members in the derived class' initializer list.

How can you get this done? Like this:

class A
{
public:
    A(int a, int b) : a_(a), b_(b) {};
    int a_, b_;
};

class B : public A
{
public:
    B() : A(0,0) 
    {
    }
};

In case anyone's interested in the Method syntax, if you have a navigation property, it's way easy:

db.Services.Where(s=>s.ServiceAssignment.LocationId == 1);

If you don't, unless there's some Join() override I'm unaware of, I think it looks pretty gnarly (and I'm a Method syntax purist):

db.Services.Join(db.ServiceAssignments, 
     s => s.Id,
     sa => sa.ServiceId, 
     (s, sa) => new {service = s, asgnmt = sa})
.Where(ssa => ssa.asgnmt.LocationId == 1)
.Select(ssa => ssa.service);

If you just need to output the date in ISO8601 format including the trailing Z and you are on at least SQL Server 2012, then you may use FORMAT:

SELECT FORMAT(GetUtcDate(),'yyyy-MM-ddTHH:mm:ssZ')

This will give you something like:

2016-02-18T21:34:14Z

Just as @Pxtl points out in a comment FORMAT may have performance implications, a cost that has to be considered compared to any flexibility it brings.

Your variable energies probably has the wrong shape:

>>> from numpy import array
>>> set([1,2,3]) & set(range(2, 10))
set([2, 3])
>>> set(array([1,2,3])) & set(range(2,10))
set([2, 3])
>>> set(array([[1,2,3],])) & set(range(2,10))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'numpy.ndarray'

And that's what happens if you read columnar data using your approach:

>>> data
array([[  1.,   2.,   3.],
       [  3.,   4.,   5.],
       [  5.,   6.,   7.],
       [  8.,   9.,  10.]])
>>> hsplit(data,3)[0]
array([[ 1.],
       [ 3.],
       [ 5.],
       [ 8.]])

Probably you can simply use

>>> data[:,0]
array([ 1.,  3.,  5.,  8.])

instead.

(P.S. Your code looks like it's undecided about whether it's data or elementdata. I've assumed it's simply a typo.)

Another way, using inline style and the spread operator

style={{
  ...completed ? { textDecoration: completed } : {}
}}

That way be useful in some situations where you want to add a bunch of properties at the same time base on the condition.

In my case this format worked on latest version of jQuery:

$('img#post_image_preview').src;

I am trying to obtain a handle on one of the views in the Action Bar

I will assume that you mean something established via android:actionLayout in your <item> element of your <menu> resource.

I have tried calling findViewById(R.id.menu_item)

To retrieve the View associated with your android:actionLayout, call findItem() on the Menu to retrieve the MenuItem, then call getActionView() on the MenuItem. This can be done any time after you have inflated the menu resource.

It depends on how the events are attached. For illustration presume we have the following click handler:

var handler = function() { alert('clicked!') };

We're going to attach it to our element using different methods, some which allow inspection and some that don't.

Method A) single event handler

element.onclick = handler;
// inspect
console.log(element.onclick); // "function() { alert('clicked!') }"

Method B) multiple event handlers

if(element.addEventListener) { // DOM standard
    element.addEventListener('click', handler, false)
} else if(element.attachEvent) { // IE
    element.attachEvent('onclick', handler)
}
// cannot inspect element to find handlers

Method C): jQuery

$(element).click(handler);

• 1.3.x

   // inspect
   var clickEvents = $(element).data("events").click;
   jQuery.each(clickEvents, function(key, value) {
       console.log(value) // "function() { alert('clicked!') }"
   })
  

• 1.4.x (stores the handler inside an object)

   // inspect
   var clickEvents = $(element).data("events").click;
   jQuery.each(clickEvents, function(key, handlerObj) {
       console.log(handlerObj.handler) // "function() { alert('clicked!') }"
       // also available: handlerObj.type, handlerObj.namespace
   })
  

• 1.7+ (very nice)

  Made using knowledge from this comment.

   events = $._data(this, 'events');
   for (type in events) {
     events[type].forEach(function (event) {
       console.log(event['handler']);
     });
   }
  

^{(See jQuery.fn.data and jQuery.data)}

Method D): Prototype (messy)

$(element).observe('click', handler);

• 1.5.x

   // inspect
   Event.observers.each(function(item) {
       if(item[0] == element) {
           console.log(item[2]) // "function() { alert('clicked!') }"
       }
   })
  

• 1.6 to 1.6.0.3, inclusive (got very difficult here)

   // inspect. "_eventId" is for < 1.6.0.3 while 
   // "_prototypeEventID" was introduced in 1.6.0.3
   var clickEvents = Event.cache[element._eventId || (element._prototypeEventID || [])[0]].click;
   clickEvents.each(function(wrapper){
       console.log(wrapper.handler) // "function() { alert('clicked!') }"
   })
  

• 1.6.1 (little better)

   // inspect
   var clickEvents = element.getStorage().get('prototype_event_registry').get('click');
   clickEvents.each(function(wrapper){
       console.log(wrapper.handler) // "function() { alert('clicked!') }"
   })
  

When clicking the resulting output in the console (which shows the text of the function), the console will navigate directly to the line of the function's declaration in the relevant JS file.

We can use reflection in this case

objectName.getClass().getName();

Example:-

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

    String name = request.getClass().getName();
}

In this case you will get name of the class which object pass to HttpServletRequest interface refference variable.

Please check this example here: Accessing Structure Members

There is explained that the right way to do it is like this:

strcpy(s1.name , "Egzona");
printf( "Name : %s\n", s1.name);

This issue appears to be causing ongoing consternation, so I will attempt to give a clearer answer than the previously posted answers, which only contain partial hints as to what's happening.

• Some time around the summer of 2014, IT Security Engineer Michele Spagnuolo (apparently employed at Google Zurich) developed a proof-of-concept exploit and supporting tool called Rosetta Flash that demonstrated a way for hackers to run malicious Flash SWF files from a remote domain in a manner which tricks browsers into thinking it came from the same domain the user was currently browsing. This allows bypassing of the "same-origin policy" and can permit hackers a variety of exploits. You can read the details here: https://miki.it/blog/2014/7/8/abusing-jsonp-with-rosetta-flash/
  • Known affected browsers: Chrome, IE
  • Possibly unaffected browsers: Firefox
• Adobe has released at least 5 different fixes over the past year while trying to comprehensively fix this vulnerability, but various major websites also introduced their own fixes earlier on in order to prevent mass vulnerability to their userbases. Among the sites to do so: Google, Youtube, Facebook, Github, and others. One component of the ad-hoc mitigation implemented by these website owners was to force the HTTP Header Content-Disposition: attachment; filename=f.txt on the returns from JSONP endpoints. This has the annoyance of causing the browser to automatically download a file called f.txt that you didn't request—but it is far better than your browser automatically running a possibly malicious Flash file.
• In conclusion, the websites you were visiting when this file spontaneously downloaded are not bad or malicious, but some domain serving content on their pages (usually ads) had content with this exploit inside it. Note that this issue will be random and intermittent in nature because even visiting the same pages consecutively will often produce different ad content. For example, the advertisement domain ad.doubleclick.net probably serves out hundreds of thousands of different ads and only a small percentage likely contain malicious content. This is why various users online are confused thinking they fixed the issue or somehow affected it by uninstalling this program or running that scan, when in fact it is all unrelated. The f.txt download just means you were protected from a recent potential attack with this exploit and you should have no reason to believe you were compromised in any way.
• The only way I'm aware that you could stop this f.txt file from being downloaded again in the future would be to block the most common domains that appear to be serving this exploit. I've put a short list below of some of the ones implicated in various posts. If you wanted to block these domains from touching your computer, you could add them to your firewall or alternatively you could use the HOSTS file technique described in the second section of this link: http://www.chromefans.org/chrome-tutorial/how-to-block-a-website-in-google-chrome.htm
• Short list of domains you could block (by no means a comprehensive list). Most of these are highly associated with adware and malware:
  • ad.doubleclick.net
  • adclick.g.doubleclick.net
  • secure-us.imrworldwide.com
  • d.turn.com
  • ad.turn.com
  • secure.insightexpressai.com
  • core.insightexpressai.com

Getting one month ago is easy with a single MySQL function:

SELECT DATE_SUB(NOW(), INTERVAL 1 MONTH);

or

SELECT NOW() - INTERVAL 1 MONTH;

Off the top of my head, I can't think of an elegant way to get the first day of last month in MySQL, but this will certainly work:

SELECT CONCAT(LEFT(NOW() - INTERVAL 1 MONTH,7),'-01');

Put them together and you get a query that solves your problem:

SELECT *
FROM your_table
WHERE t >= CONCAT(LEFT(NOW() - INTERVAL 1 MONTH,7),'-01')
AND t <= NOW() - INTERVAL 1 MONTH

Here's a couple of functions (based on Brian Bondy's example) that use WideCharToMultiByte and MultiByteToWideChar to convert between std::wstring and std::string using utf8 to not lose any data.

// Convert a wide Unicode string to an UTF8 string
std::string utf8_encode(const std::wstring &wstr)
{
    if( wstr.empty() ) return std::string();
    int size_needed = WideCharToMultiByte(CP_UTF8, 0, &wstr[0], (int)wstr.size(), NULL, 0, NULL, NULL);
    std::string strTo( size_needed, 0 );
    WideCharToMultiByte                  (CP_UTF8, 0, &wstr[0], (int)wstr.size(), &strTo[0], size_needed, NULL, NULL);
    return strTo;
}

// Convert an UTF8 string to a wide Unicode String
std::wstring utf8_decode(const std::string &str)
{
    if( str.empty() ) return std::wstring();
    int size_needed = MultiByteToWideChar(CP_UTF8, 0, &str[0], (int)str.size(), NULL, 0);
    std::wstring wstrTo( size_needed, 0 );
    MultiByteToWideChar                  (CP_UTF8, 0, &str[0], (int)str.size(), &wstrTo[0], size_needed);
    return wstrTo;
}

If you install just the JRE, it seems to be put at:

To identify which x86/x64 version of VC is needed:

Go to IIS Manager > Handler Mappings > right click then Edit *.php path. In the "Executable (optional)" field note in which version of Program Files is the php-cgi.exe installed.

You can do it by a feature of chrome's DevTools: Snippets

1. Create a new snippets
2. Copy and paste the file you would like to execute.
3. Hit CtrlEnter to run the snippet

I would suggest better cek first if the current page has a hash. Otherwise it will be undefined.

$(window).on('load', function(){        
    if( location.hash && location.hash.length ) {
       var hash = decodeURIComponent(location.hash.substr(1));
       $('ul'+hash+':first').show();;
    }       
});

You can try these two commands,it helped me.

git config --global --unset http.proxy 
git config --global --unset https.proxy

You can easily simulate a click on an element, but a click on a <select> won’t open up the dropdown.

Using multiple selects can be problematic. Perhaps you should consider radio buttons inside a container element which you can expand and contract as needed.

try it-

var radioVal = $("#myform").find("input[type='radio']:checked").val();

console.log(radioVal);

While loop will take long time to delete all items if array has 100's of items. You can empty both controls and value properties of FormArray like below.

clearFormArray = (formArray: FormArray) => { formArray.controls = []; formArray.setValue([]); }

For Python 3.x, use input(). For Python 2.x, use raw_input(). Don't forget you can add a prompt string in your input() call to create one less print statement. input("GUESS THAT NUMBER!").

The answers to this question, while they are correct, are very unnecessarily complicated. It doesn't take that much code for text to show up in the header/footer. Here is a simple example of adding text to the header/footer.

The current version of iTextSharp works by implementing a callback class which is defined by the IPdfPageEvent interface. From what I understand, it's not a good idea to add things during the OnStartPage method, so instead I will be using the OnEndPage page method. The events are triggered depending on what is happening to the PdfWriter

First, create a class which implements IPdfPageEvent. In the:

public void OnEndPage(PdfWriter writer, Document document)

function, obtain the PdfContentByte object by calling

PdfContentByte cb = writer.DirectContent;

Now you can add text very easily:

ColumnText ct = new ColumnText(cb);

cb.BeginText();
cb.SetFontAndSize(BaseFont.CreateFont(BaseFont.TIMES_ROMAN, BaseFont.CP1252, BaseFont.NOT_EMBEDDED), 12.0f);
//Note, (0,0) in this case is at the bottom of the document
cb.SetTextMatrix(document.LeftMargin, document.BottomMargin); 
cb.ShowText(String.Format("{0} {1}", "Testing Text", "Like this"));
cb.EndText();

So the full for the OnEndPage function will be:

public void OnEndPage(PdfWriter writer, Document document)
{
    PdfContentByte cb = writer.DirectContent;
    ColumnText ct = new ColumnText(cb);

    cb.BeginText();
    cb.SetFontAndSize(BaseFont.CreateFont(BaseFont.TIMES_ROMAN, BaseFont.CP1252, BaseFont.NOT_EMBEDDED), 12.0f);
    cb.SetTextMatrix(document.LeftMargin, document.BottomMargin);
    cb.ShowText(String.Format("{0} {1}", "Testing Text", "Like this"));
    cb.EndText();

}

This will show up at the bottom of your document. One last thing. Don't forget to assign the IPdfPageEvent like this:

writter.PageEvent = new PDFEvents();

To the PdfWriter writter object

For the header it is very similar. Just flip the SetTextMatrix y coordinate:

cb.SetTextMatrix(document.LeftMargin, document.PageSize.Height - document.TopMargin);

Concurrency and Parallelism Source

In a multithreaded process on a single processor, the processor can switch execution resources between threads, resulting in concurrent execution.

In the same multithreaded process in a shared-memory multiprocessor environment, each thread in the process can run on a separate processor at the same time, resulting in parallel execution.

When the process has fewer or as many threads as there are processors, the threads support system in conjunction with the operating environment ensure that each thread runs on a different processor.

For example, in a matrix multiplication that has the same number of threads and processors, each thread (and each processor) computes a row of the result.

The benefit of write-through to main memory is that it simplifies the design of the computer system. With write-through, the main memory always has an up-to-date copy of the line. So when a read is done, main memory can always reply with the requested data.

If write-back is used, sometimes the up-to-date data is in a processor cache, and sometimes it is in main memory. If the data is in a processor cache, then that processor must stop main memory from replying to the read request, because the main memory might have a stale copy of the data. This is more complicated than write-through.

Also, write-through can simplify the cache coherency protocol because it doesn't need the Modify state. The Modify state records that the cache must write back the cache line before it invalidates or evicts the line. In write-through a cache line can always be invalidated without writing back since memory already has an up-to-date copy of the line.

One more thing - on a write-back architecture software that writes to memory-mapped I/O registers must take extra steps to make sure that writes are immediately sent out of the cache. Otherwise writes are not visible outside the core until the line is read by another processor or the line is evicted.

var className=$('selector').attr('class');

or

var className=$(this).attr('class');

the classname of the current element

The standard MIME type is application/pdf. The assignment is defined in RFC 3778, The application/pdf Media Type, referenced from the MIME Media Types registry.

MIME types are controlled by a standards body, The Internet Assigned Numbers Authority (IANA). This is the same organization that manages the root name servers and the IP address space.

The use of x-pdf predates the standardization of the MIME type for PDF. MIME types in the x- namespace are considered experimental, just as those in the vnd. namespace are considered vendor-specific. x-pdf might be used for compatibility with old software.

It depends on the nature of your application. And, since you did not describe it in great detail, it is an impossible question to answer. I find Backbone to be the easiest, but I work in Angular all day. Performance is more up to the coder than the framework, in my opinion.

Are you doing heavy DOM manipulation? I would use jQuery and Backbone.

Very data driven app? Angular with its nice data binding.

Game programming? None - direct to canvas; maybe a game engine.

Just my two cents : the best way (but probably not the quickest in the short term) would probably be for each developer to work on his own database instance (see rule #1 for database work).

Installing Oracle on a developer station has become a no brainer since Oracle Database 10g Express Edition.

You can use the magic of Spring's ReflectionTestUtils.setField in order to avoid making any modifications whatsoever to your code.

The comment from Michal Stochmal provides an example:

use ReflectionTestUtils.setField(bean, "fieldName", "value"); before invoking your bean method during test.

Check out this tutorial for even more information, although you probably won't need it since the method is very easy to use

UPDATE

Since the introduction of Spring 4.2.RC1 it is now possible to set a static field without having to supply an instance of the class. See this part of the documentation and this commit.

If you are using ASP.NET MVC – you do not need an additional HTTP handler and some modifications of the web.config file. All you need – just to add some simple action in a Home/Common controller:

[HttpPost]
public JsonResult KeepSessionAlive() {
    return new JsonResult {Data = "Success"};
}

, write a piece of JavaScript code like this one (I have put it in one of site’s JavaScript file):

var keepSessionAlive = false;
var keepSessionAliveUrl = null;

function SetupSessionUpdater(actionUrl) {
    keepSessionAliveUrl = actionUrl;
    var container = $("#body");
    container.mousemove(function () { keepSessionAlive = true; });
    container.keydown(function () { keepSessionAlive = true; });
    CheckToKeepSessionAlive();
}

function CheckToKeepSessionAlive() {
    setTimeout("KeepSessionAlive()", 5*60*1000);
}

function KeepSessionAlive() {
    if (keepSessionAlive && keepSessionAliveUrl != null) {
        $.ajax({
            type: "POST",
            url: keepSessionAliveUrl,
            success: function () { keepSessionAlive = false; }
        });
    }
    CheckToKeepSessionAlive();
}

, and initialize this functionality by calling a JavaScript function:

SetupSessionUpdater('/Home/KeepSessionAlive');

Please note! I have implemented this functionality only for authorized users (there is no reason to keep session state for guests in most cases) and decision to keep session state active is not only based on – is browser open or not, but authorized user must do some activity on the site (move a mouse or type some key).

If you want n bits specific then you could first create a bitmask and then AND it with your number to take the desired bits.

Simple function to create mask from bit a to bit b.

unsigned createMask(unsigned a, unsigned b)
{
   unsigned r = 0;
   for (unsigned i=a; i<=b; i++)
       r |= 1 << i;

   return r;
}

You should check that a<=b.

If you want bits 12 to 16 call the function and then simply & (logical AND) r with your number N

r = createMask(12,16);
unsigned result = r & N;

If you want you can shift the result. Hope this helps

I had this problem while inheriting from ApiController instead of the regular Controller class. I solved it by using var container = Request.GetQueryNameValuePairs().ToLookup(x => x.Key, x => x.Value);

I followed this thread How to get Request Querystring values?

EDIT: After trying to filter through the container I was getting odd error messages. After going to my project properties and I unchecked the Optimize Code checkbox which changed so that all of a sudden the parameters in my controller where filled up from the url as I wanted.

Hopefully this will help someone with the same problem..
