Sometimes you must change the name (or check to get it automatically from compiler).

Example:

Filename = amp2-rot.png

It is not working as:

PictureBoxName.Image = resources.GetObject("amp2-rot.png")

It works, just as amp2_rot for me:

 PictureBox_L1.Image = My.Resources.Resource.amp2_rot

Using reflection:

// Return a list with all the private fields with the same type
List<T> GetAllControlsWithTypeFromControl<T>(Control parentControl)
{
    List<T> retValue = new List<T>();
    System.Reflection.FieldInfo[] fields = parentControl.GetType().GetFields(System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance);
    foreach (System.Reflection.FieldInfo field in fields)
    {
      if (field.FieldType == typeof(T))
        retValue.Add((T)field.GetValue(parentControl));
    }
}

List<TextBox> ctrls = GetAllControlsWithTypeFromControl<TextBox>(this);

Go to NugetPackage manager of you project-> Browse and search for mahApps.Metro -> install package into you project. You will see Reference added: MahApps.Metro. Then in you XAML code add:

"xmlns:mah="http://metro.mahapps.com/winfx/xaml/controls"

Where you want to use your object add:

<mah:NumericUpDown x:Name="NumericUpDown" ... /> 

Enjoy the full extensibility of the object (Bindings, triggers and so on...).

I you dont want to do it programmatically, you can manipulate to the Column width property, which is located inside the Columns property.Once you open the column edit property you can choose which column you want to edit, scroll down to layout section of the bound column properties and change the width.

An official jQuery UI ComboBox/Autocomplete component is in the making... (previously in beta for jQuery UI 1.5.x), see jQuery UI Wiki

UPDATE:

Autocomplete functionality is now a core feature of jQuery UI, see docs.

Check out Reuxables although it comes at a cost.

This is what i've done works like a charm

            private static int _x=0, _y=0;
        private static Point _point;
        public static Point LocationInForm(Control c)
        {
            if (c.Parent == null) 
            {
                _x += c.Location.X;
                _y += c.Location.Y;
                _point = new Point(_x, _y);
                _x = 0; _y = 0;
                return _point;
            }
            else if ((c.Parent is System.Windows.Forms.Form))
            {
                _point = new Point(_x, _y);
                _x = 0; _y = 0;
                return _point;
            }
            else 
            {
                _x += c.Location.X;
                _y += c.Location.Y;
                LocationInForm(c.Parent);
            }
            return new Point(1,1);
        }

A simple solution would be to iterate through the Controls list in a foreach loop. Something like this:

foreach (Control child in Controls)
{
    // Code that executes for each control.
}

So now you have your iterator, child, which is of type Control. Now do what you will with that, personally I found this in a project I did a while ago in which it added an event for this control, like this:

child.MouseDown += new MouseEventHandler(dragDown);

The code below should be enough to get you started. Tested in Opera, IE and Chrome.

<script>
var l=0;
function f(i){
im = 'i' + l;
d=document.all[im];
d.height=99;
document.all.f1.t1.value=i;
im = 'i' + i;
d=document.all[im];
d.height=1;
l=i;
}
</script>
<center>
<form id='f1'>
<input type=text value=0 id='t1'>
</form>
<script>
for (i=0;i<=50;i++)
 {
 s = "<img src='j.jpg' height=99 width=9 onMouseOver='f(" + i + ")' id='i" + i + "'>";
 document.write(s);
 }
</script>

You can treat it like an exception (KeyboardInterrupt), like any other. Make a new file and run it from your shell with the following contents to see what I mean:

import time, sys

x = 1
while True:
    try:
        print x
        time.sleep(.3)
        x += 1
    except KeyboardInterrupt:
        print "Bye"
        sys.exit()

With the property (highlighted) I can get the instance of the MainForm class. But this is a good practice? What do you recommend?

For this I use the property MainFormInstance that runs on the OnLoad method.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using LightInfocon.Data.LightBaseProvider;
using System.Configuration;

namespace SINJRectifier
{

    public partial class MainForm : Form
    {
        public MainForm()
        {
            InitializeComponent();
        }

        protected override void OnLoad(EventArgs e)
        {
            UserInterface userInterfaceObj = new UserInterface();
            this.chklbBasesList.Items.AddRange(userInterfaceObj.ExtentsList(this.chklbBasesList));
            MainFormInstance.MainFormInstanceSet = this; //Here I get the instance
        }

        private void btnBegin_Click(object sender, EventArgs e)
        {
            Maestro.ConductSymphony();
            ErrorHandling.SetExcecutionIsAllow();
        }
    }

    static class MainFormInstance  //Here I get the instance
    {
        private static MainForm mainFormInstance;

        public static MainForm MainFormInstanceSet { set { mainFormInstance = value; } }

        public static MainForm MainFormInstanceGet { get { return mainFormInstance; } }
    }
}

I use to work on UNIX-like machines, but recently I have had to do some work with Java on a Windows 7 machine. I have had that problem and this is the I've solved it. It has worked right for me so I hope it can be used for whoever who may have this problem in the future.

These steps are exposed considering a default Java installation on drive C. You should change what it is necessary in case your installation is not a default one.

Change Java default VM on Windows 7

Suppose we have installed Java 8 but for whatever reason we want to keep with Java 7.

1- Start a cmd as administrator

2- Go to C:\ProgramData\Oracle\Java

3- Rename the current directory javapath to javapath_<version_it_refers_to>. E.g.: rename javapath javapath_1.8

4- Create a javapath_<version_you_want_by_default> directory. E.g.: mkdir javapath_1.7

5- cd into it and create the following links:

cd javapath_1.7
mklink java.exe "C:\Program Files\Java\jre7\bin\java.exe"
mklink javaw.exe "C:\Program Files\Java\jre7\bin\javaw.exe"
mklink javaws.exe "C:\Program Files\Java\jre7\bin\javaws.exe"

6- cd out and create a directory link javapath pointing to the desired javapath. E.g.: mklink /D javapath javapath_1.7

7- Open the register and change the key HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment\CurrentVersion to have the value 1.7

At this point if you execute java -version you should see that you are using java version 1.7:

java version "1.7.0_71"
Java(TM) SE Runtime Environment (build 1.7.0_71-b14)
Java HotSpot(TM) 64-Bit Server VM (build 24.71-b01, mixed mode)

8- Finally it is a good idea to create the environment variable JAVA_HOME. To do that I create a directory link named CurrentVersion in C:\Program Files\Java pointing to the Java version I'm interested in. E.g.:

cd C:\Program Files\Java\
mklink /D CurrentVersion .\jdk1.7.0_71

9- And once this is done:

• Right click My Computer and select Properties.
• On the Advanced tab, select Environment Variables, and then edit/create JAVA_HOME to point to where the JDK software is located, in that case, C:\Program Files\Java\CurrentVersion

.show() and .hide() modify the css display rule. I think you want:

$(selector).css('visibility', 'hidden'); // Hide element
$(selector).css('visibility', 'visible'); // Show element

This code just fixes @CrimsonX answer's bug:

 public static T FindChild<T>(DependencyObject parent, string childName)
       where T : DependencyObject
    {    
      // Confirm parent and childName are valid. 
      if (parent == null) return null;

      T foundChild = null;

      int childrenCount = VisualTreeHelper.GetChildrenCount(parent);
      for (int i = 0; i < childrenCount; i++)
      {
        var child = VisualTreeHelper.GetChild(parent, i);
        // If the child is not of the request child type child
        T childType = child as T;
        if (childType == null)
        {
          // recursively drill down the tree
          foundChild = FindChild<T>(child, childName);

          // If the child is found, break so we do not overwrite the found child. 
          if (foundChild != null) break;
        }
        else if (!string.IsNullOrEmpty(childName))
        {
          var frameworkElement = child as FrameworkElement;
          // If the child's name is set for search
          if (frameworkElement != null && frameworkElement.Name == childName)
          {
            // if the child's name is of the request name
            foundChild = (T)child;
            break;
          }

 // recursively drill down the tree
          foundChild = FindChild<T>(child, childName);

          // If the child is found, break so we do not overwrite the found child. 
          if (foundChild != null) break;


        else
        {
          // child element found.
          foundChild = (T)child;
          break;
        }
      }

      return foundChild;
    }  

You just need to continue calling the method recursively if types are matching but names don't (this happens when you pass FrameworkElement as T). otherwise it's gonna return null and that's wrong.

Better solution

You can check item type in ItemCreated event:

protected void rptSummary_ItemCreated(Object sender, RepeaterItemEventArgs e) {
    if (e.Item.ItemType == ListItemType.Footer) {
        e.Item.FindControl(ctrl);
    }
    if (e.Item.ItemType == ListItemType.Header) {
        e.Item.FindControl(ctrl);
    }
}

Location is a struct. If there aren't any convenience members, you'll need to reassign the entire Location:

this.balancePanel.Location = new Point(
    this.optionsPanel.Location.X,
    this.balancePanel.Location.Y);

Most structs are also immutable, but in the rare (and confusing) case that it is mutable, you can also copy-out, edit, copy-in;

var loc = this.balancePanel.Location;
loc.X = this.optionsPanel.Location.X;
this.balancePanel.Location = loc;

Although I don't recommend the above, since structs should ideally be immutable.

Put the control you want to bring to front at the end of your xaml code. I.e.

<Grid>
  <TabControl ...>
  </TabControl>
  <Button Content="ALways on top of TabControl Button"/>
</Grid>

I tried the examples above, but none worked as described. However, I have a solution that is combined from some of the examples:

public static Form1 gui;
public Form1()
{
    InitializeComponent();
    gui = this;
    comms = new Comms();

}
public Comms()
{
    Form1.gui.tsStatus.Text = "test";
    Form1.gui.addLogLine("Hello from Comms class");
    Form1.gui.bn_connect.Text = "Comms";
}

This works so long as you're not using threads. Using threads would require more code and was not needed for my task.

1. Put the label inside a panel

2. Handle the ClientSizeChanged event for the panel, making the label fill the space:

   private void Panel2_ClientSizeChanged(object sender, EventArgs e)
   {
       label1.MaximumSize = new Size((sender as Control).ClientSize.Width - label1.Left, 10000);
   }
   

3. Set Auto-Size for the label to true

4. Set Dock for the label to Fill

you can put div tags inside a td tag, but not directly inside a table or tr tag. examples:

this works:

<table>_x000D_
  <tr>_x000D_
    <td> _x000D_
      <div>This will work.</div> _x000D_
    </td>_x000D_
  </tr>_x000D_
<table>

this does not work:

<table>_x000D_
  <tr>_x000D_
    <div> this does not work. </div> _x000D_
  </tr>_x000D_
</table>

nor does this work:

<table>_x000D_
  <div> this does not work. </div>_x000D_
</table>

the Headers word are not case sensitive, but on the right like the Content-Type, is good practice to write it this way, because its case sensitve. like my example below

headers = headers.set('Content-Type'

1. Just add the font awesome class like this:

   class="fa fa-plus-circle fa-3x"
   

   (You can increase the size as per 5x, 7x, 9x..)

2. You can also add custom CSS.

Try this, it's pure Ruby so there's no need to add any peripheral frameworks

if @players.include?(p.name) == false do 
  ...
end

I was struggling with a similar logic for a few days, and after checking several forums and Q&A boards to little avail it turns out the solution was actually pretty simple.

In Year 2019, we can use Javascript's ES6 Spread syntax to do it concisely and efficiently

data = [...data, {"label": 2, "value": 13}]

Examples

var data = [_x000D_
      {"label" : "1", "value" : 12},_x000D_
      {"label" : "1", "value" : 12},_x000D_
      {"label" : "1", "value" : 12},_x000D_
    ];_x000D_
    _x000D_
data = [...data, {"label" : "2", "value" : 14}] _x000D_
console.log(data)

For your case (i know it was in 2011), we can do it with map() & forEach() like below

var lab = ["1","2","3","4"];_x000D_
var val = [42,55,51,22];_x000D_
_x000D_
//Using forEach()_x000D_
var data = [];_x000D_
val.forEach((v,i) => _x000D_
   data= [...data, {"label": lab[i], "value":v}]_x000D_
)_x000D_
_x000D_
//Using map()_x000D_
var dataMap = val.map((v,i) => _x000D_
 ({"label": lab[i], "value":v})_x000D_
)_x000D_
_x000D_
console.log('data: ', data);_x000D_
console.log('dataMap : ', dataMap);

This answer won't help you to change the logging level dynamically, you need to restart the service, if you are fine restarting the service, please use the below solution

I did this to Change log4j log level and it worked for me, I have n't referred any document. I used this system property value to set my logfile name. I used the same technique to set logging level as well, and it worked

passed this as JVM parameter (I use Java 1.7)

Sorry this won't dynamically change the logging level, it requires a restart of the service

java -Dlogging.level=DEBUG -cp xxxxxx.jar  xxxxx.java

in the log4j.properties file, I added this entry

log4j.rootLogger=${logging.level},file,stdout

I tried

 java -Dlogging.level=DEBUG -cp xxxxxx.jar  xxxxx.java
 java -Dlogging.level=INFO-cp xxxxxx.jar  xxxxx.java
 java -Dlogging.level=OFF -cp xxxxxx.jar  xxxxx.java

It all worked. hope this helps!

I have these following dependencies in my pom.xml

<dependency>
            <groupId>log4j</groupId>
            <artifactId>log4j</artifactId>
            <version>1.2.17</version>
</dependency>

    <artifactId>apache-log4j-extras</artifactId>
    <version>1.2.17</version>
</dependency>

I am assuming this is a custom font. For any custom font this is what you do.

1. First download and add your font files to your project in Xcode (The files should appear as well in “Target -> Build Phases -> Copy Bundle Resources”).

2. In your Info.plist file add the key “Fonts provided by application” with type “Array”.

3. For each font you want to add to your project, create an item for the array you have created with the full name of the file including its extension (e.g. HelveticaNeue-UltraLight.ttf). Save your “Info.plist” file.

label.font = UIFont (name: "HelveticaNeue-UltraLight", size: 30)

A variable used in lambda expression should be a final or effectively final, but you can assign a value to a final one element array.

private TimeZone extractCalendarTimeZoneComponent(Calendar cal, TimeZone calTz) {
    try {
        TimeZone calTzLocal[] = new TimeZone[1];
        calTzLocal[0] = calTz;
        cal.getComponents().get("VTIMEZONE").forEach(component -> {
            TimeZone v = component;
            v.getTimeZoneId();
            if (calTzLocal[0] == null) {
                calTzLocal[0] = TimeZone.getTimeZone(v.getTimeZoneId().getValue());
            }
        });
    } catch (Exception e) {
        log.warn("Unable to determine ical timezone", e);
    }
    return null;
}

For me, this helped: I checked locale on my local shell in terminal

$ locale
LANG="cs_CZ.UTF-8"
LC_COLLATE="cs_CZ.UTF-8"

Then connected to any remote host I am using via ssh and edited file /etc/profile as root - at the end I added line:

export LANG=cs_CZ.UTF-8

After next connection it works fine in bash, ls and nano.

actually, if you already know the property, this will do it...

for example:

<a href="test.html" style="color:white;zoom:1.2" id="MyLink"></a>

    var txt = "";
    txt = getStyle(InterTabLink);
    setStyle(InterTabLink, txt.replace("zoom\:1\.2\;","");

    function setStyle(element, styleText){
        if(element.style.setAttribute)
            element.style.setAttribute("cssText", styleText );
        else
            element.setAttribute("style", styleText );
    }

    /* getStyle function */
    function getStyle(element){
        var styleText = element.getAttribute('style');
        if(styleText == null)
            return "";
        if (typeof styleText == 'string') // !IE
            return styleText;
        else  // IE
            return styleText.cssText;
    } 

Note that this only works for inline styles... not styles you've specified through a class or something like that...

Other note: you may have to escape some characters in that replace statement, but you get the idea.

This solved my problem, from preventign that an event gets fired by a children:

doSmth(){_x000D_
  // what ever_x000D_
}

        <div (click)="doSmth()">_x000D_
            <div (click)="$event.stopPropagation()">_x000D_
                <my-component></my-component>_x000D_
            </div>_x000D_
        </div>

This is actually an area ripe for discussion, with many subtle techniques available. It is important that you select/develop a technique that meets your needs including: screen readers, images/css/scripting on/off combinations, seo, etc.

Here are some good resources to get started down the road of standardista image replacement techniques:

I struggled with this for over a week and finally figured out how to make this work!

My issue was that everything would scroll as a 'block'. The text itself was scrolling, but as a chunk rather than line by line. This obviously didn't work for me, because it would cut off lines at the bottom. All of the previous solutions did not work for me, so I crafted my own.

Here is the easiest solution by far:

Make a class file called: 'PerfectScrollableTextView' inside a package, then copy and paste this code in:

import android.content.Context;
import android.graphics.Rect;
import android.util.AttributeSet;
import android.widget.TextView;

public class PerfectScrollableTextView extends TextView {

    public PerfectScrollableTextView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        setVerticalScrollBarEnabled(true);
        setHorizontallyScrolling(false);
    }

    public PerfectScrollableTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
        setVerticalScrollBarEnabled(true);
        setHorizontallyScrolling(false);
    }

    public PerfectScrollableTextView(Context context) {
        super(context);
        setVerticalScrollBarEnabled(true);
        setHorizontallyScrolling(false);
    }

    @Override
    protected void onFocusChanged(boolean focused, int direction, Rect previouslyFocusedRect) {
        if(focused)
            super.onFocusChanged(focused, direction, previouslyFocusedRect);
    }

    @Override
    public void onWindowFocusChanged(boolean focused) {
        if(focused)
            super.onWindowFocusChanged(focused);
    }

    @Override
    public boolean isFocused() {
        return true;
    }
}

Finally change your 'TextView' in XML:

From: <TextView

To: <com.your_app_goes_here.PerfectScrollableTextView

You don't need any webpack configuration for this..

In your component just give image path. By default react will know its in public directory.

<img src="/image.jpg" alt="image" />

You are right. This has nothing to do with jQuery though.

var myArray = [];
myArray.push("foo");
// myArray now contains "foo" at index 0.

The error you're getting appears to be the result of the fact that there is no underscore between "chartered" and "flight" in the table name. I assume you want something like this where the name of the table is chartered_flight.

CREATE TABLE chartered_flight(flight_no NUMBER(4) PRIMARY KEY
, customer_id NUMBER(6) REFERENCES customer(customer_id)
, aircraft_no NUMBER(4) REFERENCES aircraft(aircraft_no)
, flight_type VARCHAR2 (12)
, flight_date DATE NOT NULL
, flight_time INTERVAL DAY TO SECOND NOT NULL
, takeoff_at CHAR (3) NOT NULL
, destination CHAR (3) NOT NULL)

Generally, there is no benefit to declaring a column as CHAR(3) rather than VARCHAR2(3). Declaring a column as CHAR(3) doesn't force there to be three characters of (useful) data. It just tells Oracle to space-pad data with fewer than three characters to three characters. That is unlikely to be helpful if someone inadvertently enters an incorrect code. Potentially, you could declare the column as VARCHAR2(3) and then add a CHECK constraint that LENGTH(takeoff_at) = 3.

CREATE TABLE chartered_flight(flight_no NUMBER(4) PRIMARY KEY
, customer_id NUMBER(6) REFERENCES customer(customer_id)
, aircraft_no NUMBER(4) REFERENCES aircraft(aircraft_no)
, flight_type VARCHAR2 (12)
, flight_date DATE NOT NULL
, flight_time INTERVAL DAY TO SECOND NOT NULL
, takeoff_at CHAR (3) NOT NULL CHECK( length( takeoff_at ) = 3 )
, destination CHAR (3) NOT NULL CHECK( length( destination ) = 3 )
)

Since both takeoff_at and destination are airport codes, you really ought to have a separate table of valid airport codes and define foreign key constraints between the chartered_flight table and this new airport_code table. That ensures that only valid airport codes are added and makes it much easier in the future if an airport code changes.

And from a naming convention standpoint, since both takeoff_at and destination are airport codes, I would suggest that the names be complementary and indicate that fact. Something like departure_airport_code and arrival_airport_code, for example, would be much more meaningful.

You can configure your build.gradle file for proguard implementation. It can be at module level or the project level.

 buildTypes {

    debug {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'

    }

}

The configuration shown is for debug level but you can write you own build flavors like shown below inside buildTypes:

    myproductionbuild{
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'

Better to have your debug with minifyEnabled false and productionbuild and other builds as minifyEnabled true.

Copy your proguard-rules.txt file in the root of your module or project folder like

$YOUR_PROJECT_DIR\YoutProject\yourmodule\proguard-rules.txt

You can change the name of your file as you want. After configuration use one of the three options available to generate your build as per the buildType

1. Go to gradle task in right panel and search for assembleRelease/assemble(#your_defined_buildtype) under module tasks

2. Go to Build Variant in Left Panel and select the build from drop down

3. Go to project root directory in File Explorer and open cmd/terminal and run

Linux ./gradlew assembleRelease or assemble(#your_defined_buildtype)

Windows gradlew assembleRelease or assemble(#your_defined_buildtype)

You can find apk in your module/build directory.

More about the configuration and proguard files location is available at the link

http://tools.android.com/tech-docs/new-build-system/user-guide#TOC-Running-ProGuard

if your array looks like

array = [
 {:name => "Hitesh" , :age => 27 , :place => "xyz"} ,
 {:name => "John" , :age => 26 , :place => "xtz"} ,
 {:name => "Anil" , :age => 26 , :place => "xsz"} 
]

And you Want To know if some value is already present in your array. Use Find Method

array.find {|x| x[:name] == "Hitesh"}

This will return object if Hitesh is present in name otherwise return nil

For mixed position and index, use .ix. BUT you need to make sure that your index is not of integer, otherwise it will cause confusions.

df.ix[0, 'COL_NAME'] = x

Update:

Alternatively, try

df.iloc[0, df.columns.get_loc('COL_NAME')] = x

Example:

import pandas as pd
import numpy as np

# your data
# ========================
np.random.seed(0)
df = pd.DataFrame(np.random.randn(10, 2), columns=['col1', 'col2'], index=np.random.randint(1,100,10)).sort_index()

print(df)


      col1    col2
10  1.7641  0.4002
24  0.1440  1.4543
29  0.3131 -0.8541
32  0.9501 -0.1514
33  1.8676 -0.9773
36  0.7610  0.1217

58  0.9787  2.2409
75 -0.1032  0.4106
76  0.4439  0.3337

# .iloc with get_loc
# ===================================
df.iloc[0, df.columns.get_loc('col2')] = 100

df

      col1      col2
10  1.7641  100.0000
24  0.1440    1.4543
29  0.3131   -0.8541
32  0.9501   -0.1514
33  1.8676   -0.9773
36  0.7610    0.1217
56  1.4941   -0.2052
58  0.9787    2.2409

$mail->IsSMTP();
$mail->Host = "smtp.gmail.com";
$mail->SMTPAuth = true;
$mail->SMTPSecure = "ssl";
$mail->Username = "[email protected]";
$mail->Password = "**********";
$mail->Port = "465";

That is a working configuration.

try to replace what you have

Alternatively to what the others are correctly suggesting, I find it easier usually to toggle CSS classes, instead of individual CSS settings (especially background image URLs). For example:

// in CSS 
.bg1 
{
  background-image: url(/some/image/url/here.jpg);
}

.bg2 
{
  background-image: url(/another/image/url/there.jpg);
}

// in JS
// based on value of imageUrl, determine what class to remove and what class to add.
$('myOjbect').removeClass('bg1').addClass('bg2');

You might want to try screenfly. It worked great for me.

Your question already expresses the purpose. You must see this might be useful for logging or throwing exceptions.

For example:

public void DoStuff(object input)
{
    if (input == null)
    {
        throw new ArgumentNullException(nameof(input));
    }
}

This is good. If I change the name of the variable, the code will break instead of returning an exception with an incorrect message.

Of course, the uses are not limited to this simple situation. You can use nameof whenever it would be useful to code the name of a variable or property.

The uses are manifold when you consider various binding and reflection situations. It's an excellent way to bring what were run time errors to compile time.

Solution native Javascript :

document.getElementById("theSelectId").insertBefore(new Option('', ''), document.getElementById("theSelectId").firstChild);

example : http://codepen.io/anon/pen/GprybL

You can use any:

print any(df.column == 07311954)
True       #true if it contains the number, false otherwise

If you rather want to see how many times '07311954' occurs in a column you can use:

df.column[df.column == 07311954].count()

Determining of root cause is not an issue since Go 1.8; field name now is shown in the error message:

json: cannot unmarshal object into Go struct field Comment.author of type string

I think what you're looking for is:

textBox1.Select();

in the constructor. (This is in C#. Maybe in VB that would be the same but without the semicolon.)

From http://msdn.microsoft.com/en-us/library/system.windows.forms.control.focus.aspx :

Focus is a low-level method intended primarily for custom control authors. Instead, application programmers should use the Select method or the ActiveControl property for child controls, or the Activate method for forms.

I also favor the RegEx solution. The code will be much cleaner. I would hesitate to use toLowerCase() in situations where I knew the strings were going to be large, since strings are immutable and would have to be copied. Also, the matches() solution might be confusing because it takes a regular expression as an argument (searching for "Need$le" cold be problematic).

Building on some of the above examples:

public boolean containsIgnoreCase( String haystack, String needle ) {
  if(needle.equals(""))
    return true;
  if(haystack == null || needle == null || haystack .equals(""))
    return false; 

  Pattern p = Pattern.compile(needle,Pattern.CASE_INSENSITIVE+Pattern.LITERAL);
  Matcher m = p.matcher(haystack);
  return m.find();
}

example call: 

String needle = "Need$le";
String haystack = "This is a haystack that might have a need$le in it.";
if( containsIgnoreCase( haystack, needle) ) {
  System.out.println( "Found " + needle + " within " + haystack + "." );
}

(Note: you might want to handle NULL and empty strings differently depending on your needs. I think they way I have it is closer to the Java spec for strings.)

Speed critical solutions could include iterating through the haystack character by character looking for the first character of the needle. When the first character is matched (case insenstively), begin iterating through the needle character by character, looking for the corresponding character in the haystack and returning "true" if all characters get matched. If a non-matched character is encountered, resume iteration through the haystack at the next character, returning "false" if a position > haystack.length() - needle.length() is reached.

Parsing the Feed

With jQuery's jFeed

_{(Don't really recommend that one, see the other options.)}

jQuery.getFeed({
   url     : FEED_URL,
   success : function (feed) {
      console.log(feed.title);
      // do more stuff here
   }
});

With jQuery's Built-in XML Support

$.get(FEED_URL, function (data) {
    $(data).find("entry").each(function () { // or "item" or whatever suits your feed
        var el = $(this);

        console.log("------------------------");
        console.log("title      : " + el.find("title").text());
        console.log("author     : " + el.find("author").text());
        console.log("description: " + el.find("description").text());
    });
});

With jQuery and the Google AJAX Feed API

$.ajax({
  url      : document.location.protocol + '//ajax.googleapis.com/ajax/services/feed/load?v=1.0&num=10&callback=?&q=' + encodeURIComponent(FEED_URL),
  dataType : 'json',
  success  : function (data) {
    if (data.responseData.feed && data.responseData.feed.entries) {
      $.each(data.responseData.feed.entries, function (i, e) {
        console.log("------------------------");
        console.log("title      : " + e.title);
        console.log("author     : " + e.author);
        console.log("description: " + e.description);
      });
    }
  }
});

But that means you're relient on them being online and reachable.

Building Content

Once you've successfully extracted the information you need from the feed, you could create DocumentFragments (with document.createDocumentFragment() containing the elements (created with document.createElement()) you'll want to inject to display your data.

Injecting the content

Select the container element that you want on the page and append your document fragments to it, and simply use innerHTML to replace its content entirely.

Something like:

$('#rss-viewer').append(aDocumentFragmentEntry);

or:

$('#rss-viewer')[0].innerHTML = aDocumentFragmentOfAllEntries.innerHTML;

&lt;h3&gt;With jQuery&#39;s jFeed&lt;/h3&gt;

&lt;p&gt;Try this, with the &lt;a href=&quot;http://plugins.jquery.com/project/jFeed&quot; rel=&quot;nofollow&quot;&gt;jFeed&lt;/a&gt; &lt;a href=&quot;http://www.jquery.com/&quot; rel=&quot;nofollow&quot;&gt;jQuery&lt;/a&gt; plug-in&lt;/p&gt;

&lt;/code&gt;&lt;/pre&gt;

&lt;h3&gt;With jQuery and the Google AJAX APIs&lt;/h3&gt;

&lt;p&gt;Otherwise, &lt;a href=&quot;https://developers.google.com/feed/&quot; rel=&quot;nofollow&quot;&gt;Google&#39;s AJAX Feed API&lt;/a&gt; allows you to get the feed as a JSON object:&lt;/p&gt;

  dataType : &#39;json&#39;,
  success  : function (data) {
    if (data.responseData.feed &amp;amp;&amp;amp; data.responseData.feed.entries) {
      $.each(data.responseData.feed.entries, function (i, e) {
        console.log(&quot;------------------------&quot;);
        console.log(&quot;title      : &quot; + e.title);
        console.log(&quot;author     : &quot; + e.author);
        console.log(&quot;description: &quot; + e.description);
      });
    }
  }
});
&lt;/code&gt;&lt;/pre&gt;

&lt;p&gt;But that means you&#39;re relient on them being online and reachable.&lt;/p&gt;

&lt;hr&gt;

&lt;p&gt;Once you&#39;ve successfully extracted the information you need from the feed, you need to create document fragments containing the elements you&#39;ll want to inject to display your data.&lt;/p&gt;

Also be aware of the class of "interruption vulnerabilities" that allow arbitrary memory locations to be read and written!

These affect functions such as trim(), rtrim(), ltrim(), explode(), strchr(), strstr(), substr(), chunk_split(), strtok(), addcslashes(), str_repeat() and more. This is largely, but not exclusively, due to the call-time pass-by-reference feature of the language that has been deprecated for 10 years but not disabled.

Fore more info, see Stefan Esser’s talk about interruption vulnerabilities and other lower-level PHP issues at BlackHat USA 2009 Slides Paper

This paper/presentation also shows how dl() can be used to execute arbitrary system code.

I am afraid there is no way to get the query string parameters parsed separately from the post parameters. BTW the fact that such API absent may mean that probably you should check your design. Why are you using query string when sending POST? If you really want to send more data into URL use REST-like convention, e.g. instead of sending

http://mycompany.com/myapp/myservlet?first=11&second=22

say:

http://mycompany.com/myapp/myservlet/11/22

This was a really a helpful thread, I followed the same steps as @junjie mentioned but for me something weird happened, the below are the steps I did.

1. Went to developer portal and revoked the certificate which was about to expire.
2. Went to XCode6.4 and in the Account settings, the certificate still showed valid, I went crazy.
3. Then I opened XCode7, there the certificate was shown with "Reset" button instead of create and I hit the reset button and later in the portal I was able to see an extended certificate present. This is what Apple says about Reset button

If Xcode detects an issue with a signing identity, it displays an appropriate action in Accounts preferences. If Xcode displays a Create button, the signing identity doesn’t exist in Member Center or on your Mac. If Xcode displays a Reset button, the signing identity is not usable on your Mac—for example, it is missing the private key. If you click the Reset button, Xcode revokes and requests the corresponding certificate.

4. I tried creating an Appstore ipa with that, just to test and it worked fine so I am saved, but still not sure what has happened. May be I had multiple accounts configured in my Mac, dont know.

i figured out why RETURN is not unconditionally returning from the stored procedure. The error i'm seeing is while the stored procedure is being compiled - not when it's being executed.

Consider an imaginary stored procedure:

CREATE PROCEDURE dbo.foo AS

INSERT INTO ExistingTable
EXECUTE LinkedServer.Database.dbo.SomeProcedure

Even though this stord proedure contains an error (maybe it's because the objects have a differnet number of columns, maybe there is a timestamp column in the table, maybe the stored procedure doesn't exist), you can still save it. You can save it because you're referencing a linked server.

But when you actually execute the stored procedure, SQL Server then compiles it, and generates a query plan.

My error is not happening on line 114, it is on line 114. SQL Server cannot compile the stored procedure, that's why it's failing.

And that's why RETURN does not return, because it hasn't even started yet.

The default (when created with the designer) is:

label.ForeColor = SystemColors.ControlText;

This should respect the system color settings (e.g. these "high contrast" schemes for visual impaired).

Mxx's answer is correct but you the python crypt.crypt() method is not safe when different operating systems are involved (related to glibc hash algorithm used on your system.)

For example, It won't work if your generate your hash from MacOS and run a playbook on linux. In such case , You can use passlib (pip install passlib to install locally).

from passlib.hash import md5_crypt
python -c 'import crypt; print md5_crypt.encrypt("This is my Password,salt="SomeSalt")'
'$1$SomeSalt$UqddPX3r4kH3UL5jq5/ZI.'

You can just follow instructions from the Homebrew on Linux docs, but I think it is better to understand what the instructions are trying to achieve.

Understanding the installation steps can save some time

Step 1: Choose location

First of all, it is important to understand that linuxbrew will be installed on the /home directory and not inside /home/your-user (the ~ directory).
(See the reason for that at the end of answer).
Keep this in mind when you run the other steps below.

Step 2: Add linuxbrew binaries to /home :

The installation script will do it for us:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Step 3: Check that /linuxbrew was added to the relevant location

This can be done by simply navigating to /home.
Notice that the docs are showing it as a one-liner by adding test -d <linuxbrew location> before each command.

(Read more about the test command in here).

Step 4: Export relevant environment variables to terminal

We need to add linuxbrew to PATH and add some more environment variables to the current terminal.

We can just add the following exports to terminal (wait don't do it..):

export PATH="/home/linuxbrew/.linuxbrew/bin:/home/linuxbrew/.linuxbrew/sbin${PATH+:$PATH}";

export HOMEBREW_PREFIX="/home/linuxbrew/.linuxbrew";
export HOMEBREW_CELLAR="/home/linuxbrew/.linuxbrew/Cellar";
export HOMEBREW_REPOSITORY="/home/linuxbrew/.linuxbrew/Homebrew";
export MANPATH="/home/linuxbrew/.linuxbrew/share/man${MANPATH+:$MANPATH}:";
export INFOPATH="/home/linuxbrew/.linuxbrew/share/info:${INFOPATH:-}";

Or simply run (If your linuxbrew folder is on other location then /home - change the path):

eval $(/home/linuxbrew/.linuxbrew/bin/brew shellenv)

(*) Because brew command is not yet identified by the current terminal (this is what we're solving right now) we'll have to specify the full path to the brew binary: /home/linuxbrew/.linuxbrew/bin/brew shellenv

Test this step by:

1 ) Run brew from current terminal to see if it identifies the command.

2 ) Run printenv and check if all environment variables were exported and that you see /home/linuxbrew/.linuxbrew/bin:/home/linuxbrew/.linuxbrew/sbin on PATH.

Step 5: Ensure step 4 is running on each terminal

We need to add step 4 to ~/.profile (in case of Debian/Ubuntu):

echo "eval \$($(brew --prefix)/bin/brew shellenv)" >> ~/.profile

For CentOS/Fedora/Red Hat - replace ~/.profile with ~/.bash_profile.

Step 6: Ensure that ~/.profile or ~/.bash_profile are being executed when new terminal is opened

If you executed step 5 and failed to run brew from new terminal - add a test command like echo "Hi!" to ~/.profile or ~/.bash_profile.
If you don't see Hi! when you open a new terminal - go to the terminal preferences and ensure that the attribute of 'run command as login shell' is set.
Read more in here.

Why the installation script installs Homebrew to /home/linuxbrew/.linuxbrew - from here:

The installation script installs Homebrew to /home/linuxbrew/.linuxbrew using sudo if possible and in your home directory at ~/.linuxbrew otherwise. Homebrew does not use sudo after installation.
Using /home/linuxbrew/.linuxbrew allows the use of more binary packages (bottles) than installing in your personal home directory.

The prefix /home/linuxbrew/.linuxbrew was chosen so that users without admin access can ask an admin to create a linuxbrew role account and still benefit from precompiled binaries.

If you do not yourself have admin privileges, consider asking your admin staff to create a linuxbrew role account for you with home directory /home/linuxbrew.

As you said, that string intern() method will first find from the String pool, if it finds, then it will return the object that points to that, or will add a new String into the pool.

    String s1 = "Hello";
    String s2 = "Hello";
    String s3 = "Hello".intern();
    String s4 = new String("Hello");

    System.out.println(s1 == s2);//true
    System.out.println(s1 == s3);//true
    System.out.println(s1 == s4.intern());//true

The s1 and s2 are two objects pointing to the String pool "Hello", and using "Hello".intern() will find that s1 and s2. So "s1 == s3" returns true, as well as to the s3.intern().

The most basic way to iterate over a hash is as follows:

hash.each do |key, value|
  puts key

While everyone will generally agree that Javascript encryption is a bad idea, there are a few small use cases where slowing down the attack is better than nothing. You can start with YUI Compressor (as @Ben Alpert) said, or JSMin, Uglify, or many more.

However, the main case in which I want to really 'hide stuff' is when I'm publishing an email address. Note, there is the problem of Chrome when you click on 'inspect element'. It will show your original code: every time. This is why obfuscation is generally regarded as being a better way to go.

On that note, I take a two pronged attack, purely to slow down spam bots. I Obfuscate/minify the js and then run it again through an encoder (again, this second step is completely pointless in chrome).

While not exactly a pure Javascript encoder, the best html encoder I have found is http://hivelogic.com/enkoder/. It will turn this:

};
//-->
//]]>
</script>
<a href="#" onclick="return c(this);"><img src="images/email.png" /></a>

into this:

Maybe it's enough to slow down a few spam bots. I haven't had any spam come through using this (!yet).

You can run the dropdb command from the command line:

dropdb 'database name'

Note that you have to be a superuser or the database owner to be able to drop it.

You can also check the pg_stat_activity view to see what type of activity is currently taking place against your database, including all idle processes.

SELECT * FROM pg_stat_activity WHERE datname='database name';

Note that from PostgreSQL v13 on, you can disconnect the users automatically with

DROP DATABASE dbname FORCE;

or

dropdb -f dbname

This is the best way IMO. No need for properties, or readonly:

public static class Constants
{
   public const string SomeConstant = "Some value";
}

I was having the same problem but only with a few machines. I found that using Invoke-Command to run the same command on the remote server worked.

So instead of:

Get-WmiObject win32_SystemEnclosure -ComputerName $hostname -Authentication Negotiate

Use this:

Invoke-Command -ComputerName $hostname -Authentication Negotiate -ScriptBlock {Get-WmiObject win32_SystemEnclosure}

If the "Customer don't want to install and buy MS Office on a server not at any price", then you cannot use Excel ... But I cannot get the trick: it's all about one basic Office licence which costs something like 150 USD ... And I guess that spending time finding an alternative will cost by far more than this amount!

It's a weird design, but the TableLayoutPanel.RowCount property doesn't reflect the count of the RowStyles collection, and similarly for the ColumnCount property and the ColumnStyles collection.

What I've found I needed in my code was to manually update RowCount/ColumnCount after making changes to RowStyles/ColumnStyles.

Here's an example of code I've used:

    /// <summary>
    /// Add a new row to our grid.
    /// </summary>
    /// The row should autosize to match whatever is placed within.
    /// <returns>Index of new row.</returns>
    public int AddAutoSizeRow()
    {
        Panel.RowStyles.Add(new RowStyle(SizeType.AutoSize));
        Panel.RowCount = Panel.RowStyles.Count;
        mCurrentRow = Panel.RowCount - 1;
        return mCurrentRow;
    }

Other thoughts

• I've never used DockStyle.Fill to make a control fill a cell in the Grid; I've done this by setting the Anchors property of the control.

• If you're adding a lot of controls, make sure you call SuspendLayout and ResumeLayout around the process, else things will run slow as the entire form is relaid after each control is added.

Symbolic or soft link (files or directories, more flexible and self documenting)

#     Source                             Link
ln -s /home/jake/doc/test/2000/something /home/jake/xxx

Hard link (files only, less flexible and not self documenting)

#   Source                             Link
ln /home/jake/doc/test/2000/something /home/jake/xxx

More information: man ln

/home/jake/xxx is like a new directory. To avoid "is not a directory: No such file or directory" error, as @trlkly comment, use relative path in the target, that is, using the example:

1. cd /home/jake/
2. ln -s /home/jake/doc/test/2000/something xxx

A nice handy overview table from the Bash Hackers Wiki:

where c in the third row is the first character of $IFS, the Input Field Separator, a shell variable.

If the arguments are to be stored in a script variable and the arguments are expected to contain spaces, I wholeheartedly recommend employing a "$*" trick with the input field separator set to tab IFS=$'\t'.

If you are sure you haven't messed the jar, then please clean the project and perform mvn clean install. This should solve the problem.

Since this post is ranking high in Google for "Create Directory Tree", I am going to post an answer that will work for Windows — this will work using Win32 API compiled for UNICODE or MBCS. This is ported from Mark's code above.

Since this is Windows we are working with, directory separators are BACK-slashes, not forward slashes. If you would rather have forward slashes, change '\\' to '/'

It will work with:

c:\foo\bar\hello\world

and

c:\foo\bar\hellp\world\

(i.e.: does not need trailing slash, so you don't have to check for it.)

Before saying "Just use SHCreateDirectoryEx() in Windows", note that SHCreateDirectoryEx() is deprecated and could be removed at any time from future versions of Windows.

bool CreateDirectoryTree(LPCTSTR szPathTree, LPSECURITY_ATTRIBUTES lpSecurityAttributes = NULL){
    bool bSuccess = false;

    if(!bCD){
        dwLastError = GetLastError();
    }else{
        return true;
    }
    switch(dwLastError){
        case ERROR_ALREADY_EXISTS:
            bSuccess = true;
            break;
        case ERROR_PATH_NOT_FOUND:
            {
                TCHAR szPrev[MAX_PATH] = {0};
                LPCTSTR szLast = _tcsrchr(szPathTree,'\\');
                _tcsnccpy(szPrev,szPathTree,(int)(szLast-szPathTree));

                        bSuccess = (GetLastError()==ERROR_ALREADY_EXISTS);
                    }
                }else{
                    bSuccess = false;
                }
            }
            break;

$ nvm alias default {NODE_VERSION}

when we use the above command, only update the node version but the npm still uses the old version.

Here is another solution for update the both node and npm, in my case i want to use node 8.9.4 and i have used the below command.

$ nvm use default 8.9.4

And the command returns the output.

Now using node v8.9.4 (npm v5.6.0)

You can declare an overloaded function by declaring the function as having a type which has multiple invocation signatures:

interface IFoo
{
    bar: {
        (s: string): number;
        (n: number): string;
    }
}

Then the following:

var foo1: IFoo = ...;

var n: number = foo1.bar('baz');     // OK
var s: string = foo1.bar(123);       // OK
var a: number[] = foo1.bar([1,2,3]); // ERROR

The actual definition of the function must be singular and perform the appropriate dispatching internally on its arguments.

For example, using a class (which could implement IFoo, but doesn't have to):

class Foo
{
    public bar(s: string): number;
    public bar(n: number): string;
    public bar(arg: any): any 
    {
        if (typeof(arg) === 'number')
            return arg.toString();
        if (typeof(arg) === 'string')
            return arg.length;
    }
}

What's interesting here is that the any form is hidden by the more specifically typed overrides.

var foo2: new Foo();

var n: number = foo2.bar('baz');     // OK
var s: string = foo2.bar(123);       // OK
var a: number[] = foo2.bar([1,2,3]); // ERROR

Here is an implementation of a delete cookie function with unicode support from Mozilla:

function removeItem(sKey, sPath, sDomain) {
    document.cookie = encodeURIComponent(sKey) + 
                  "=; expires=Thu, 01 Jan 1970 00:00:00 GMT" + 
                  (sDomain ? "; domain=" + sDomain : "") + 
                  (sPath ? "; path=" + sPath : "");
}

removeItem("cookieName");

If you use AngularJs, try $cookies.remove (underneath it uses a similar approach):

$cookies.remove('cookieName');

This obviously won't work in many cases, but if your Makefile was created by CMake you might be able to run make help.

$ make help
The following are some of the valid targets for this Makefile:

... clean
... depend
... install
etc

Use &:

foreach($arr as &$value) {
    $value = $newVal;
}

& passes a value of the array as a reference and does not create a new instance of the variable. Thus if you change the reference the original value will change.

PHP documentation for Passing by Reference

Edit 2018

This answer seems to be favored by a lot of people on the internet, which is why I decided to add more information and words of caution.
While pass by reference in foreach (or functions) is a clean and short solution, for many beginners this might be a dangerous pitfall.

1. Loops in PHP don't have their own scope. - @Mark Amery

   This could be a serious problem when the variables are being reused in the same scope. Another SO question nicely illustrates why that might be a problem.

2. As foreach relies on the internal array pointer in PHP 5, changing it within the loop may lead to unexpected behavior. - PHP docs for foreach.

   Unsetting a record or changing the hash value (the key) during the iteration on the same loop could lead to potentially unexpected behaviors in PHP < 7. The issue gets even more complicated when the array itself is a reference.

3. Foreach performance.
   In general, PHP prefers pass by value due to the copy-on-write feature. It means that internally PHP will not create duplicate data unless the copy of it needs to be changed. It is debatable whether pass by reference in foreach would offer a performance improvement. As it is always the case, you need to test your specific scenario and determine which option uses less memory and CPU time. For more information see the SO post linked below by NikiC.

4. Code readability.
   Creating references in PHP is something that quickly gets out of hand. If you are a novice and don't have full control of what you are doing, it is best to stay away from references. For more information about & operator take a look at this guide: Reference — What does this symbol mean in PHP?
   For those who want to learn more about this part of PHP language: PHP References Explained

A very nice technical explanation by @NikiC of the internal logic of PHP foreach loops:
How does PHP 'foreach' actually work?

I had window 7 (64 bit) and Python 2.7.12, I uninstalled it by clicking the python installer from the "download" directory then I selected remove python then I clicked “ finish”.
I also removed the remaining python associated directory & files from the c: drive and also from “my documents” folder, since I created some files there.

Since Array(3) will create an un-iterable array, it must be populated to allow the usage of the map Array method. A way to "convert" is to destruct it inside Array-brackets, which "forces" the Array to be filled with undefined values, same as Array(N).fill(undefined)

<table>
    { [...Array(3)].map((_, index) => <tr key={index}/>) }
</table>

Another way would be via Array fill():

<table>
    { Array(3).fill(<tr/>) }
</table>

?? Problem with above example is the lack of key prop, which is a must.
(Using an iterator's index as key is not recommended)

Nested Nodes:

const tableSize = [3,4]
const Table = (
    <table>
        <tbody>
        { [...Array(tableSize[0])].map((tr, trIdx) => 
            <tr key={trIdx}> 
              { [...Array(tableSize[1])].map((a, tdIdx, arr) => 
                  <td key={trIdx + tdIdx}>
                  {arr.length * trIdx + tdIdx + 1}
                  </td>
               )}
            </tr>
        )}
        </tbody>
    </table>
);

ReactDOM.render(Table, document.querySelector('main'))

td{ border:1px solid silver; padding:1em; }

In my case, I have reinstalled ubuntu and the user name is changed from previous. In this case the the generated ssh key also differs from the previous one.

The issue solved by just copy the current ssh public key, in the repository. The key will be available in your user's /home/.ssh/id_rsa.pub

Watch again:

char dest[5];
char src[5] = "test";

printf("String: %s\n", do_something(dest, src));

Focus on this line:

printf("String: %s\n", do_something(dest, src));

You can clearly see that the do_something function is not declared!

If you look a little further,

printf("String: %s\n", do_something(dest, src));

char *do_something(char *dest, const char *src)
{
return dest;
}

you will see that you declare the function after you use it.

You will need to modify this part with this code:

char *do_something(char *dest, const char *src)
{
return dest;
}

printf("String: %s\n", do_something(dest, src));

Cheers ;)

This also works:

    ...
    WHERE
        (FirstName IS NULL OR FirstName = ISNULL(@FirstName, FirstName)) AND
        (LastName IS NULL OR LastName = ISNULL(@LastName, LastName)) AND
        (Title IS NULL OR Title = ISNULL(@Title, Title))

Most of the time this happens due to less memory space. first check then try some other tricks .

If you want today's date without the time, just use Date.today

Linux Mint 19. Helped for me:

sudo apt install tk-dev

P.S. Recompile python interpreter after package install.

If, after reading the other questions and viewing the links mentioned in the comment sections, you still can't figure it out, read on.

First of all, where you're going wrong is the offset.

It should look more like this...

set mydate=%date:~10,4%%date:~6,2%/%date:~4,2%
echo %mydate%

If the date was Tue 12/02/2013 then it would display it as 2013/02/12.

To remove the slashes, the code would look more like

set mydate=%date:~10,4%%date:~7,2%%date:~4,2%
echo %mydate%

which would output 20130212

And a hint for doing it in the future, if mydate equals something like %date:~10,4%%date:~7,2% or the like, you probably forgot a tilde (~).

matches return true if the whole string matches the given pattern. find tries to find a substring that matches the pattern.

First glob them, then unlink.

You might try removing the BufferedWriter and just using the FileWriter directly. On a modern system there's a good chance you're just writing to the drive's cache memory anyway.

It takes me in the range of 4-5 seconds to write 175MB (4 million strings) -- this is on a dual-core 2.4GHz Dell running Windows XP with an 80GB, 7200-RPM Hitachi disk.

Can you isolate how much of the time is record retrieval and how much is file writing?

The good news is that if you need to make a case-sensitive query, it is very easy to do:

SELECT *  FROM `table` WHERE BINARY `column` = 'value'

So, for future reference for anybody who doesn't want to spend two days searching the internet to figure this out, when you encode byte arrays into QR Codes, you have to use the ISO-8859-1character set, not UTF-8.

I'd suggest following a few debugging steps.

First run the query directly against the DB. Confirm it is bringing results back. Even with something as simple as this you can find you've made a mistake, or the table is empty, or somesuch oddity.

If the above is ok, then try looping and echoing out the contents of $row just directly into the HTML to see what you've getting back in the mysql_query - see if it matches what you got directly in the DB.

If your data is output onto the page, then look at what's going wrong in your HTML formatting.

However, if nothing is output from $row, then figure out why the mysql_query isn't working e.g. does the user have permission to query that DB, do you have an open DB connection, can the webserver connect to the DB etc [something on these lines can often be a gotcha]

Changing your query slightly to

$sql = mysql_query("SELECT username FROM users") or die(mysql_error());  

may help to highlight any errors: php manual

You can't do this using sharer.php, but you can do something similar using the Dialog API. http://developers.facebook.com/docs/reference/dialogs/

The catch is you must create a dummy Facebook application just to have an app_id. Note that your Facebook application doesn't have to do ANYTHING at all. Just be sure that it is properly configured, and you should be all set.

Some thoughts:

class Model(model.Model):
    _image=models.ImageField(upload_to='folder')
    thumb=models.ImageField(upload_to='folder')
    description=models.CharField()

    def set_image(self, val):
        self._image = val
        self._image_changed = True

        # Or put whole logic in here
        small = rescale_image(self.image,width=100,height=100)
        self.image_small=SimpleUploadedFile(name,small_pic)

    def get_image(self):
        return self._image

    image = property(get_image, set_image)

    # this is not needed if small_image is created at set_image
    def save(self, *args, **kwargs):
        if getattr(self, '_image_changed', True):
            small=rescale_image(self.image,width=100,height=100)
            self.image_small=SimpleUploadedFile(name,small_pic)
        super(Model, self).save(*args, **kwargs)

Not sure if it would play nice with all pseudo-auto django tools (Example: ModelForm, contrib.admin etc).

You can use axis:

> axis(side=1, at=c(0:23))

That is, something like this:

plot(0:23, d, type='b', axes=FALSE)
axis(side=1, at=c(0:23))
axis(side=2, at=seq(0, 600, by=100))

Install the colorlog package, you can use colors in your log messages immediately:

• Obtain a logger instance, exactly as you would normally do.
• Set the logging level. You can also use the constants like DEBUG and INFO from the logging module directly.
• Set the message formatter to be the ColoredFormatter provided by the colorlog library.

import colorlog

logger = colorlog.getLogger()
logger.setLevel(colorlog.colorlog.logging.DEBUG)

handler = colorlog.StreamHandler()
handler.setFormatter(colorlog.ColoredFormatter())
logger.addHandler(handler)

logger.debug("Debug message")
logger.info("Information message")
logger.warning("Warning message")
logger.error("Error message")

Deleting node modules folder worked for me.

• Delete the node modules folder
• Run npm install.
• Re-run the application and it should work.

if my understanding of your initial JSON is correct, either of these solutions might help you loop through all ip ids & assign each one, a new object.

// initial JSON
var ips = {ipId1: {}, ipId2: {}};

// Solution1
Object.keys(ips).forEach(function(key) {
  ips[key] = {name: 'value', anotherName: 'another value'};
});

// Solution 2
Object.keys(ips).forEach(function(key) {
  Object.assign(ips[key],{name: 'value', anotherName: 'another value'});
});

To confirm:

console.log(JSON.stringify(ips, null, 2));

The above statement spits:

{
  "ipId1": {
    "name":"value",
    "anotherName":"another value"
  },
  "ipId2": {
    "name":"value",
    "anotherName":"another value"
  }
}

You will have to use a setTimeout so I see your issue as

I have a script that is generated by PHP, and so am not able to put it into two different functions

What prevents you from generating two functions in your script?

function fizz() {
    var a;
    a = 'buzz';
    // sleep x desired
    a = 'complete';
}

Could be rewritten as

function foo() {
    var a; // variable raised so shared across functions below
    function bar() { // consider this to be start of fizz
        a = 'buzz';
        setTimeout(baz, x); // start wait
    } // code split here for timeout break
    function baz() { // after wait
        a = 'complete';
    } // end of fizz
    bar(); // start it
}

You'll notice that a inside baz starts as buzz when it is invoked and at the end of invocation, a inside foo will be "complete".

Basically, wrap everything in a function, move all variables up into that wrapping function such that the contained functions inherit them. Then, every time you encounter wait NUMBER seconds you echo a setTimeout, end the function and start a new function to pick up where you left off.

@Html.Raw(Json.Encode(object)) can be used to convert the View Modal Object to JSON

1.This will search XMLHelpers/XMLHelpers.psm1 in current folder

Import-Module (Resolve-Path('XMLHelpers'))

2.This will search XMLHelpers.psm1 in current folder

Import-Module (Resolve-Path('XMLHelpers.psm1'))

You can use percent values:

background: yellow url("arrow1.gif") no-repeat 95% 50%;

Not pixel perfect, but…

I've found the solution in this thread

@(ViewContext.RouteData.Values["parameterName"])

Did you try using the -ArgumentList parameter:

invoke-command -ComputerName studio -ScriptBlock { param ( $myarg ) ping.exe $myarg } -ArgumentList localhost   

http://technet.microsoft.com/en-us/library/dd347578.aspx

An example of invoking a program that is not in the path and has a space in it's folder path:

invoke-command -ComputerName Computer1 -ScriptBlock { param ($myarg) & 'C:\Program Files\program.exe' -something $myarg } -ArgumentList "myArgValue"

If the value of the argument is static you can just provide it in the script block like this:

invoke-command -ComputerName Computer1 -ScriptBlock { & 'C:\Program Files\program.exe' -something "myArgValue" } 

DataRow dataRow = dataTable.AsEnumerable().FirstOrDefault(r => Convert.ToInt32(r["ID"]) == 5);
if (dataRow != null)
{
    // code
}

If it is a typed DataSet:

MyDatasetType.MyDataTableRow dataRow = dataSet.MyDataTable.FirstOrDefault(r => r.ID == 5);
if (dataRow != null)
{
    // code
}

Object does not have forEach, it belongs to Array prototype. If you want to iterate through each key-value pair in the object and take the values. You can do this:

Object.keys(a).forEach(function (key){
    console.log(a[key]);
});

Usage note: For an object v = {"cat":"large", "dog": "small", "bird": "tiny"};, Object.keys(v) gives you an array of the keys so you get ["cat","dog","bird"]

If you're looking for a good alias to do this plus not blow up cd if you aren't in a git dir:

alias ..g='git rev-parse && cd "$(git rev-parse --show-cdup)"'

You can always create a custom Matcher using argThat

Mockito.verify(yourMockHere).methodCallToBeVerifiedOnYourMockHere(ArgumentMatchers.argThat(new ArgumentMatcher<Object>() {
    @Override
    public boolean matches(Object argument) {
        YourTypeHere[] yourArray = (YourTypeHere[]) argument;
        // Do whatever you like, here is an example:
        if (!yourArray[0].getStringValue().equals("first_arr_val")) {
            return false;
        }
        return true;
    }
}));

I found that, sometimes, nuget packages will install (what I'm guessing are) .NET Core required components or other items that conflict with the already-installed framework. My solution there was to open the project (.csproj) file and remove those references. For example, System.IO, System.Threading and such, tend to be added when Microsoft.Bcl is included via some recently installed NuGet package. There's no reason for specific versions of those in my projects, so I remove the references and the project builds. Hope that helps.

You can search your project file for "reference" and remove the conflicts. If they're included in System, get rid of them, and the build should work. This may not answer all cases of this issue - I'm making sure you know what worked for me :)

Example of what I commented out:

<!-- <Reference Include="System.Runtime, Version=2.6.9.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, processorArchitecture=MSIL"> -->_x000D_
  <!-- <HintPath>$(SolutionDir)packages\Microsoft.Bcl.1.1.9\lib\net40\System.Runtime.dll</HintPath> -->_x000D_
  <!-- <Private>True</Private> -->_x000D_
<!-- </Reference> -->

You can even write this:

    private string foo = "foo";

    private string bar
    {
        get => $"{foo}bar";
        set
        {
            foo = value;
        }
    }

Try this:

for(String str: myList) {
    if(str.trim().equals("A"))
       return true;
}
return false;

You need to use str.equals or str.equalsIgnoreCase instead of contains because contains in string works not the same as contains in List

List<String> s = Arrays.asList("BAB", "SAB", "DAS");
s.contains("A"); // false
"BAB".contains("A"); // true

Because both a and b have only one axis, as their shape is (3), and the axis parameter specifically refers to the axis of the elements to concatenate.

this example should clarify what concatenate is doing with axis. Take two vectors with two axis, with shape (2,3):

a = np.array([[1,5,9], [2,6,10]])
b = np.array([[3,7,11], [4,8,12]])

concatenates along the 1st axis (rows of the 1st, then rows of the 2nd):

np.concatenate((a,b), axis=0)
array([[ 1,  5,  9],
       [ 2,  6, 10],
       [ 3,  7, 11],
       [ 4,  8, 12]])

concatenates along the 2nd axis (columns of the 1st, then columns of the 2nd):

np.concatenate((a, b), axis=1)
array([[ 1,  5,  9,  3,  7, 11],
       [ 2,  6, 10,  4,  8, 12]])

to obtain the output you presented, you can use vstack

a = np.array([1,2,3])
b = np.array([4,5,6])
np.vstack((a, b))
array([[1, 2, 3],
       [4, 5, 6]])

You can still do it with concatenate, but you need to reshape them first:

np.concatenate((a.reshape(1,3), b.reshape(1,3)))
array([[1, 2, 3],
       [4, 5, 6]])

Finally, as proposed in the comments, one way to reshape them is to use newaxis:

np.concatenate((a[np.newaxis,:], b[np.newaxis,:]))

Just write

this.getRootView();

As explained in this thread on the cxf-user mailing list, rather than having the CXFServlet load its own spring context from user-webservice-servlet.xml, you can just load the whole lot into the root context. Rename your existing user-webservice-servlet.xml to some other name (e.g. user-webservice-beans.xml) then change your contextConfigLocation parameter to something like:

<servlet>
  <servlet-name>myservlet</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
  <servlet-name>myservlet</servlet-name>
  <url-pattern>*.htm</url-pattern>
</servlet-mapping>

<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>
    /WEB-INF/applicationContext.xml
    /WEB-INF/user-webservice-beans.xml
  </param-value>
</context-param>

<servlet>
  <servlet-name>user-webservice</servlet-name>
  <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
  <load-on-startup>2</load-on-startup>
</servlet>

<servlet-mapping>
  <servlet-name>user-webservice</servlet-name>
  <url-pattern>/UserService/*</url-pattern>
</servlet-mapping>

What worked for me was echo $testVar | tr "\n" " "

Where testVar contained my variable/script-output

Another way to do simultaneous animations if you want to call them separately (eg. from different code) is to use queue. Again, as with Tinister's answer you would have to use animate for this and not fadeIn:

$('.tooltip').css('opacity', 0);
$('.tooltip').show();
...

$('.tooltip').animate({opacity: 1}, {queue: false, duration: 'slow'});
$('.tooltip').animate({ top: "-10px" }, 'slow');

Just 2 simple steps to solve your issue

First of all check AppendDataBoundItems property and make it assign false

Secondly clear all the items using property .clear()

{
ddl1.Items.Clear();
ddl1.datasource = sql1;
ddl1.DataBind();
}

Use the shell globbing syntax:

grep pattern -r --include=\*.{cpp,h} rootdir

The syntax for --exclude is identical.

Note that the star is escaped with a backslash to prevent it from being expanded by the shell (quoting it, such as --include="*.{cpp,h}", would work just as well). Otherwise, if you had any files in the current working directory that matched the pattern, the command line would expand to something like grep pattern -r --include=foo.cpp --include=bar.h rootdir, which would only search files named foo.cpp and bar.h, which is quite likely not what you wanted.

Here's a complete example of jHackTheRipper's answer for the TL;DR crowd. :-) In this case, I wanted to run g++-4.5 on an Ubuntu system that defaults to 4.6. As root:

apt-get install g++-4.5
update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.6 100
update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.5 50
update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.6 100
update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.5 50
update-alternatives --install /usr/bin/cpp cpp-bin /usr/bin/cpp-4.6 100
update-alternatives --install /usr/bin/cpp cpp-bin /usr/bin/cpp-4.5 50
update-alternatives --set g++ /usr/bin/g++-4.5
update-alternatives --set gcc /usr/bin/gcc-4.5
update-alternatives --set cpp-bin /usr/bin/cpp-4.5

Here, 4.6 is still the default (aka "auto mode"), but I explicitly switch to 4.5 temporarily (manual mode). To go back to 4.6:

update-alternatives --auto g++
update-alternatives --auto gcc
update-alternatives --auto cpp-bin

(Note the use of cpp-bin instead of just cpp. Ubuntu already has a cpp alternative with a master link of /lib/cpp. Renaming that link would remove the /lib/cpp link, which could break scripts.)

The reason why this happen is that diff dependency use same lib of diff version.
So, there are 3 steps or (1 step) to solve this problem.

1st

Add

configurations.all {
    resolutionStrategy.force 'com.google.code.findbugs:jsr305:2.0.1'
}

to your build.gradle file in android {...}

2nd

Open terminal in android studio
run ./gradlew -q app:dependencies command.

3rd

Click Clean Project from menu bar of android studio in Build list.
It will rebuild the project, and then remove code in 1st step.

Maybe you need just exec 2nd step. I can't rollback when error occurs. Have a try.

• run this command locale to get what locale is used. Such as:

LANG=en_US.UTF-8
LANGUAGE=en_US:en
LC_CTYPE=zh_CN.UTF-8
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

• search for the listed locales list in first step in /etc/locale-gen file. Uncomment to used ones
• run locale-gen to generate newly added locales

Using ASCII(RIGHT(ProductAlternateKey, 1)) you can see that the right most character in row 2 is a Line Feed or Ascii Character 10.

This can not be removed using the standard LTrim RTrim functions.

You could however use (REPLACE(ProductAlternateKey, CHAR(10), '')

You may also want to account for carriage returns and tabs. These three (Line feeds, carriage returns and tabs) are the usual culprits and can be removed with the following :

LTRIM(RTRIM(REPLACE(REPLACE(REPLACE(ProductAlternateKey, CHAR(10), ''), CHAR(13), ''), CHAR(9), '')))

If you encounter any more "white space" characters that can't be removed with the above then try one or all of the below:

--NULL
Replace([YourString],CHAR(0),'');
--Horizontal Tab
Replace([YourString],CHAR(9),'');
--Line Feed
Replace([YourString],CHAR(10),'');
--Vertical Tab
Replace([YourString],CHAR(11),'');
--Form Feed
Replace([YourString],CHAR(12),'');
--Carriage Return
Replace([YourString],CHAR(13),'');
--Column Break
Replace([YourString],CHAR(14),'');
--Non-breaking space
Replace([YourString],CHAR(160),'');

This list of potential white space characters could be used to create a function such as :

Create Function [dbo].[CleanAndTrimString] 
(@MyString as varchar(Max))
Returns varchar(Max)
As
Begin
    --NULL
    Set @MyString = Replace(@MyString,CHAR(0),'');
    --Horizontal Tab
    Set @MyString = Replace(@MyString,CHAR(9),'');
    --Line Feed
    Set @MyString = Replace(@MyString,CHAR(10),'');
    --Vertical Tab
    Set @MyString = Replace(@MyString,CHAR(11),'');
    --Form Feed
    Set @MyString = Replace(@MyString,CHAR(12),'');
    --Carriage Return
    Set @MyString = Replace(@MyString,CHAR(13),'');
    --Column Break
    Set @MyString = Replace(@MyString,CHAR(14),'');
    --Non-breaking space
    Set @MyString = Replace(@MyString,CHAR(160),'');

    Set @MyString = LTRIM(RTRIM(@MyString));
    Return @MyString
End
Go

Which you could then use as follows:

Select 
    dbo.CleanAndTrimString(ProductAlternateKey) As ProductAlternateKey
from DimProducts

Try:

  string output = YourString.replaceAll("\\s","")

s - indicates space character (tab characters etc)

I had the same problem, and found the solution here :

Solution for JPQL queries

This is supported for JPQL queries within the JPA specification.

Step 1: Declare a simple bean class

package com.path.to;

public class SurveyAnswerStatistics {
  private String answer;
  private Long   cnt;

  public SurveyAnswerStatistics(String answer, Long cnt) {
    this.answer = answer;
    this.count  = cnt;
  }
}

Step 2: Return bean instances from the repository method

public interface SurveyRepository extends CrudRepository<Survey, Long> {
    @Query("SELECT " +
           "    new com.path.to.SurveyAnswerStatistics(v.answer, COUNT(v)) " +
           "FROM " +
           "    Survey v " +
           "GROUP BY " +
           "    v.answer")
    List<SurveyAnswerStatistics> findSurveyCount();
}

Important notes

1. Make sure to provide the fully-qualified path to the bean class, including the package name. For example, if the bean class is called MyBean and it is in package com.path.to, the fully-qualified path to the bean will be com.path.to.MyBean. Simply providing MyBean will not work (unless the bean class is in the default package).
2. Make sure to call the bean class constructor using the new keyword. SELECT new com.path.to.MyBean(...) will work, whereas SELECT com.path.to.MyBean(...) will not.
3. Make sure to pass attributes in exactly the same order as that expected in the bean constructor. Attempting to pass attributes in a different order will lead to an exception.
4. Make sure the query is a valid JPA query, that is, it is not a native query. @Query("SELECT ..."), or @Query(value = "SELECT ..."), or @Query(value = "SELECT ...", nativeQuery = false) will work, whereas @Query(value = "SELECT ...", nativeQuery = true) will not work. This is because native queries are passed without modifications to the JPA provider, and are executed against the underlying RDBMS as such. Since new and com.path.to.MyBean are not valid SQL keywords, the RDBMS then throws an exception.

Solution for native queries

As noted above, the new ... syntax is a JPA-supported mechanism and works with all JPA providers. However, if the query itself is not a JPA query, that is, it is a native query, the new ... syntax will not work as the query is passed on directly to the underlying RDBMS, which does not understand the new keyword since it is not part of the SQL standard.

In situations like these, bean classes need to be replaced with Spring Data Projection interfaces.

Step 1: Declare a projection interface

package com.path.to;

public interface SurveyAnswerStatistics {
  String getAnswer();

  int getCnt();
}

Step 2: Return projected properties from the query

public interface SurveyRepository extends CrudRepository<Survey, Long> {
    @Query(nativeQuery = true, value =
           "SELECT " +
           "    v.answer AS answer, COUNT(v) AS cnt " +
           "FROM " +
           "    Survey v " +
           "GROUP BY " +
           "    v.answer")
    List<SurveyAnswerStatistics> findSurveyCount();
}

Use the SQL AS keyword to map result fields to projection properties for unambiguous mapping.

What if you set the timezone of the role you are using?

ALTER ROLE my_db_user IN DATABASE my_database
    SET "TimeZone" TO 'UTC';

Will this be of any use?

Try this:

if ( jQuery('#postageyes').is(':checked') ){ ... }

It works fine, Ex :

$.ajax({
    url: "http://localhost:11141/Search/BasicSearchContent?ContentTitle=" + "?????",
    type: 'GET',
    cache: false,
    success: function(result) {
        //  alert(jQuery.dataType);
        if (result) {
            //  var dd = JSON.parse(result);
            alert(result[0].Id)
        }

    },
    error: function() {
        alert("No");
    }
});

Finally, you need to use this statement ...

result[0].Whatever

You can float your column divs using float: left; and give them widths.

And to make sure none of your other content gets messed up, you can wrap the floated divs within a parent div and give it some clear float styling.

Hope this helps.

For Xamarin Android this was the only solution that worked for me: another stack overflow post

If you are using AndroidClientHandler, you need to supply a SSLSocketFactory and a custom implementation of HostnameVerifier with all checks disabled. To do this, you’ll need to subclass AndroidClientHandler and override the appropriate methods.

internal class BypassHostnameVerifier : Java.Lang.Object, IHostnameVerifier
{
    public bool Verify(string hostname, ISSLSession session)
    {
        return true;
    }
}
 
internal class InsecureAndroidClientHandler : AndroidClientHandler
{
    protected override SSLSocketFactory ConfigureCustomSSLSocketFactory(HttpsURLConnection connection)
    {
        return SSLCertificateSocketFactory.GetInsecure(1000, null);
    }
 
    protected override IHostnameVerifier GetSSLHostnameVerifier(HttpsURLConnection connection)
    {
        return new BypassHostnameVerifier();
    }
}

And then

var httpClient = new System.Net.Http.HttpClient(new InsecureAndroidClientHandler());

You can use ::after to create a 0px-height block after the <h4>, which effectively moves anything after the <h4> to the next line:

h4 {_x000D_
  display: inline;_x000D_
}_x000D_
h4::after {_x000D_
  content: "";_x000D_
  display: block;_x000D_
}

<ul>_x000D_
  <li>_x000D_
    Text, text, text, text, text. <h4>Sub header</h4>_x000D_
    Text, text, text, text, text._x000D_
  </li>_x000D_
</ul>

200,300, 400, 500 are all very generic. If you want generic, 400 is OK.

422 is used by an increasing number of APIs, and is even used by Rails out of the box.

No matter which status code you pick for your API, someone will disagree. But I prefer 422 because I think of '400 + text status' as too generic. Also, you aren't taking advantage of a JSON-ready parser; in contrast, a 422 with a JSON response is very explicit, and a great deal of error information can be conveyed.

Speaking of JSON response, I tend to standardize on the Rails error response for this case, which is:

{
    "errors" :
    { 
        "arg1" : ["error msg 1", "error msg 2", ...]
        "arg2" : ["error msg 1", "error msg 2", ...]
    }
}

This format is perfect for form validation, which I consider the most complex case to support in terms of 'error reporting richness'. If your error structure is this, it will likely handle all your error reporting needs.

If you are trying to return back the ID within the scope, using the SCOPE_IDENTITY() would be a better approach. I would not advice to use @@IDENTITY, as this can return any ID.

CREATE PROC [dbo].[sp_Test] (
  @myID int output,
  @myFirstName nvarchar(50),
  @myLastName nvarchar(50),
  @myAddress nvarchar(50),
  @myPort int
) AS
BEGIN
    INSERT INTO Dvds (myFirstName, myLastName, myAddress, myPort)
    VALUES (@myFirstName, @myLastName, @myAddress, @myPort);

    SET @myID = SCOPE_IDENTITY();
END
GO

If you want to push commit on git repository, plz make sure you have merged all commit from other branches.

After merging if you are unable to push commit, Use the push command with -f

git push -f origin branch-name

Where origin is the name of your remote repo.

I had to disable selinux to make this work. Note. The system needs to be rebooted for selinux to take effect.

I think all the answers are lacking something. I prefer using something like this

$('li.current_sub').prevUntil("li.par_cat").prev();

Saves you not adding :first inside the selector and is easier to read and understand. prevUntil() method has a better performance as well rather than using prevAll()

Hint lies in Webapi2 auto generated account controller

Have this property with getter defined as

public string UserIdentity
        {
            get
            {
                var user = UserManager.FindByName(User.Identity.Name);
                return user;//user.Email
            }
        }

and in order to get UserManager - In WebApi2 -do as Romans (read as AccountController) do

public ApplicationUserManager UserManager
        {
            get { return HttpContext.Current.GetOwinContext().GetUserManager<ApplicationUserManager>(); }
        }

This should be compatible in IIS and self host mode

It is worth noting that @Marius's second answer could be used as pure Javascript solution.

document.getElementById('elementId').tagName

SQL Server allows the following (be careful to use single quotes instead of double)

UPDATE User
SET UserId = 12345
   , Name = 'J Doe'
   , Location = 'USA'
   , Bio='my bio
spans 
multiple
lines!'
WHERE UserId = 12345

Since you've already looked into strtok just continue down the same path and split your string using space (' ') as a delimiter, then use something as realloc to increase the size of the array containing the elements to be passed to execvp.

See the below example, but keep in mind that strtok will modify the string passed to it. If you don't want this to happen you are required to make a copy of the original string, using strcpy or similar function.

char    str[]= "ls -l";
char ** res  = NULL;
char *  p    = strtok (str, " ");
int n_spaces = 0, i;


/* split string and append tokens to 'res' */

while (p) {
  res = realloc (res, sizeof (char*) * ++n_spaces);

  if (res == NULL)
    exit (-1); /* memory allocation failed */

  res[n_spaces-1] = p;

  p = strtok (NULL, " ");
}

/* realloc one extra element for the last NULL */

res = realloc (res, sizeof (char*) * (n_spaces+1));
res[n_spaces] = 0;

/* print the result */

for (i = 0; i < (n_spaces+1); ++i)
  printf ("res[%d] = %s\n", i, res[i]);

/* free the memory allocated */

free (res);

res[0] = ls
res[1] = -l
res[2] = (null)

This is (of course) totally VM-dependent.

Browsing through the source code of OpenJDK 7 and 8 java.util.ArrayList, .Hashtable, .AbstractCollection, .PriorityQueue, and .Vector, you can see this claim being repeated:

/**
 * Some VMs reserve some header words in an array.
 * Attempts to allocate larger arrays may result in
 * OutOfMemoryError: Requested array size exceeds VM limit
 */
private static final int MAX_ARRAY_SIZE = Integer.MAX_VALUE - 8;

which is added by Martin Buchholz (Google) on 2010-05-09; reviewed by Chris Hegarty (Oracle).

So, probably we can say that the maximum "safe" number would be 2 147 483 639 (Integer.MAX_VALUE - 8) and "attempts to allocate larger arrays may result in OutOfMemoryError".

(Yes, Buchholz's standalone claim does not include backing evidence, so this is a calculated appeal to authority. Even within OpenJDK itself, we can see code like return (minCapacity > MAX_ARRAY_SIZE) ? Integer.MAX_VALUE : MAX_ARRAY_SIZE; which shows that MAX_ARRAY_SIZE does not yet have a real use.)

No. The only officially supported tool for downloading and updating Cygwin packages is the setup.exe file you used for the initial install, although that can be invoked with command line arguments to help the process.

From that same page:

The basic reason for not having a more full-featured package manager is that such a program would need full access to all of Cygwin's POSIX functionality. That is, however, difficult to provide in a Cygwin-free environment, such as exists on first installation. Additionally, Windows does not easily allow overwriting of in-use executables so installing a new version of the Cygwin DLL while a package manager is using the DLL is problematic.

As others have already said, parameters passed through the command line can be accessed in batch files with the notation %1 to %9. There are also two other tokens that you can use:

• %0 is the executable (batch file) name as specified in the command line.
• %* is all parameters specified in the command line -- this is very useful if you want to forward the parameters to another program.

There are also lots of important techniques to be aware of in addition to simply how to access the parameters.

Checking if a parameter was passed

This is done with constructs like IF "%~1"=="", which is true if and only if no arguments were passed at all. Note the tilde character which causes any surrounding quotes to be removed from the value of %1; without a tilde you will get unexpected results if that value includes double quotes, including the possibility of syntax errors.

Handling more than 9 arguments (or just making life easier)

If you need to access more than 9 arguments you have to use the command SHIFT. This command shifts the values of all arguments one place, so that %0 takes the value of %1, %1 takes the value of %2, etc. %9 takes the value of the tenth argument (if one is present), which was not available through any variable before calling SHIFT (enter command SHIFT /? for more options).

SHIFT is also useful when you want to easily process parameters without requiring that they are presented in a specific order. For example, a script may recognize the flags -a and -b in any order. A good way to parse the command line in such cases is

:parse
IF "%~1"=="" GOTO endparse
IF "%~1"=="-a" REM do something
IF "%~1"=="-b" REM do something else
SHIFT
GOTO parse
:endparse
REM ready for action!

This scheme allows you to parse pretty complex command lines without going insane.

Substitution of batch parameters

For parameters that represent file names the shell provides lots of functionality related to working with files that is not accessible in any other way. This functionality is accessed with constructs that begin with %~.

For example, to get the size of the file passed in as an argument use

ECHO %~z1

To get the path of the directory where the batch file was launched from (very useful!) you can use

ECHO %~dp0

You can view the full range of these capabilities by typing CALL /? in the command prompt.

>>> '\x9c'.decode('cp1252')
u'\u0153'
>>> print '\x9c'.decode('cp1252')

Give your log a name. I called mine "wawa".

In Android Studio, go to Android-> Edit Filter Configurations

Then type in the name you gave the logs. In my case, it's called "wawa". Here are some examples of the types of filters you can do. You can filter by System.out, System.err, Logs, or package names:

Try this if you are using GET:

$curl = curl_init($url);

curl_setopt_array($curl, array(
    CURLOPT_URL => $url,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_ENCODING => "",
    CURLOPT_MAXREDIRS => 10,
    CURLOPT_TIMEOUT => 30,
    CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
    CURLOPT_CUSTOMREQUEST => "GET",
    CURLOPT_HTTPHEADER => array(
        "Cache-Control: no-cache"
    ),
));

$response = curl_exec($curl);
curl_close($curl);

Minimal runnable multi-file scope example

Here I illustrate how static affects the scope of function definitions across multiple files.

a.c

#include <stdio.h>

/* Undefined behavior: already defined in main.
 * Binutils 2.24 gives an error and refuses to link.
 * https://stackoverflow.com/questions/27667277/why-does-borland-compile-with-multiple-definitions-of-same-object-in-different-c
 */
/*void f() { puts("a f"); }*/

/* OK: only declared, not defined. Will use the one in main. */
void f(void);

/* OK: only visible to this file. */
static void sf() { puts("a sf"); }

void a() {
    f();
    sf();
}

main.c

#include <stdio.h>

void a(void);        

void f() { puts("main f"); }

static void sf() { puts("main sf"); }

void m() {
    f();
    sf();
}

int main() {
    m();
    a();
    return 0;
}

GitHub upstream.

Compile and run:

gcc -c a.c -o a.o
gcc -c main.c -o main.o
gcc -o main main.o a.o
./main

Output:

main f
main sf
main f
a sf

Interpretation

• there are two separate functions sf, one for each file
• there is a single shared function f

As usual, the smaller the scope, the better, so always declare functions static if you can.

In C programming, files are often used to represent "classes", and static functions represent "private" methods of the class.

A common C pattern is to pass a this struct around as the first "method" argument, which is basically what C++ does under the hood.

What standards say about it

C99 N1256 draft 6.7.1 "Storage-class specifiers" says that static is a "storage-class specifier".

6.2.2/3 "Linkages of identifiers" says static implies internal linkage:

If the declaration of a file scope identifier for an object or a function contains the storage-class specifier static, the identifier has internal linkage.

and 6.2.2/2 says that internal linkage behaves like in our example:

In the set of translation units and libraries that constitutes an entire program, each declaration of a particular identifier with external linkage denotes the same object or function. Within one translation unit, each declaration of an identifier with internal linkage denotes the same object or function.

where "translation unit" is a source file after preprocessing.

How GCC implements it for ELF (Linux)?

With the STB_LOCAL binding.

If we compile:

int f() { return 0; }
static int sf() { return 0; }

and disassemble the symbol table with:

readelf -s main.o

the output contains:

Num:    Value          Size Type    Bind   Vis      Ndx Name
  5: 000000000000000b    11 FUNC    LOCAL  DEFAULT    1 sf
  9: 0000000000000000    11 FUNC    GLOBAL DEFAULT    1 f

so the binding is the only significant difference between them. Value is just their offset into the .bss section, so we expect it to differ.

STB_LOCAL is documented on the ELF spec at http://www.sco.com/developers/gabi/2003-12-17/ch4.symtab.html:

STB_LOCAL Local symbols are not visible outside the object file containing their definition. Local symbols of the same name may exist in multiple files without interfering with each other

which makes it a perfect choice to represent static.

Functions without static are STB_GLOBAL, and the spec says:

When the link editor combines several relocatable object files, it does not allow multiple definitions of STB_GLOBAL symbols with the same name.

which is coherent with the link errors on multiple non static definitions.

If we crank up the optimization with -O3, the sf symbol is removed entirely from the symbol table: it cannot be used from outside anyways. TODO why keep static functions on the symbol table at all when there is no optimization? Can they be used for anything?

• Same for variables: https://stackoverflow.com/a/14339047/895245
• extern is the opposite of static, and functions are already extern by default: How do I use extern to share variables between source files?

C++ anonymous namespaces

In C++, you might want to use anonymous namespaces instead of static, which achieves a similar effect, but further hides type definitions: Unnamed/anonymous namespaces vs. static functions

You should return json always, but change its status, or in following example the ResponseCode property:

if(callbackResults.ResponseCode!="200"){
    /* Some error, you can add a message too */
} else {
    /* All fine, proceed with code */
};

UPDATE 24.04.2016.

I've created tutorial on my page https://madebydenis.com/ajax-load-posts-on-wordpress/ about implementing this on Twenty Sixteen theme, so feel free to check it out :)

EDIT

I've tested this on Twenty Fifteen and it's working, so it should be working for you.

In index.php (assuming that you want to show the posts on the main page, but this should work even if you put it in a page template) I put:

    <div id="ajax-posts" class="row">
        <?php
            $postsPerPage = 3;
            $args = array(
                    'post_type' => 'post',
                    'posts_per_page' => $postsPerPage,
                    'cat' => 8
            );

            $loop = new WP_Query($args);

            while ($loop->have_posts()) : $loop->the_post();
        ?>

         <div class="small-12 large-4 columns">
                <h1><?php the_title(); ?></h1>
                <p><?php the_content(); ?></p>
         </div>

         <?php
                endwhile;
        wp_reset_postdata();
         ?>
    </div>
    <div id="more_posts">Load More</div>

This will output 3 posts from category 8 (I had posts in that category, so I used it, you can use whatever you want to). You can even query the category you're in with

$cat_id = get_query_var('cat');

This will give you the category id to use in your query. You could put this in your loader (load more div), and pull with jQuery like

<div id="more_posts" data-category="<?php echo $cat_id; ?>">>Load More</div>

And pull the category with

var cat = $('#more_posts').data('category');

But for now, you can leave this out.

Next in functions.php I added

wp_localize_script( 'twentyfifteen-script', 'ajax_posts', array(
    'ajaxurl' => admin_url( 'admin-ajax.php' ),
    'noposts' => __('No older posts found', 'twentyfifteen'),
));

Right after the existing wp_localize_script. This will load WordPress own admin-ajax.php so that we can use it when we call it in our ajax call.

At the end of the functions.php file I added the function that will load your posts:

function more_post_ajax(){

    $ppp = (isset($_POST["ppp"])) ? $_POST["ppp"] : 3;
    $page = (isset($_POST['pageNumber'])) ? $_POST['pageNumber'] : 0;

    header("Content-Type: text/html");

    $args = array(
        'suppress_filters' => true,
        'post_type' => 'post',
        'posts_per_page' => $ppp,
        'cat' => 8,
        'paged'    => $page,
    );

    $loop = new WP_Query($args);

    $out = '';

    if ($loop -> have_posts()) :  while ($loop -> have_posts()) : $loop -> the_post();
        $out .= '<div class="small-12 large-4 columns">
                <h1>'.get_the_title().'</h1>
                <p>'.get_the_content().'</p>
         </div>';

    endwhile;
    endif;
    wp_reset_postdata();
    die($out);
}

add_action('wp_ajax_nopriv_more_post_ajax', 'more_post_ajax');
add_action('wp_ajax_more_post_ajax', 'more_post_ajax');

Here I've added paged key in the array, so that the loop can keep track on what page you are when you load your posts.

If you've added your category in the loader, you'd add:

$cat = (isset($_POST['cat'])) ? $_POST['cat'] : '';

And instead of 8, you'd put $cat. This will be in the $_POST array, and you'll be able to use it in ajax.

Last part is the ajax itself. In functions.js I put inside the $(document).ready(); enviroment

var ppp = 3; // Post per page
var cat = 8;
var pageNumber = 1;


function load_posts(){
    pageNumber++;
    var str = '&cat=' + cat + '&pageNumber=' + pageNumber + '&ppp=' + ppp + '&action=more_post_ajax';
    $.ajax({
        type: "POST",
        dataType: "html",
        url: ajax_posts.ajaxurl,
        data: str,
        success: function(data){
            var $data = $(data);
            if($data.length){
                $("#ajax-posts").append($data);
                $("#more_posts").attr("disabled",false);
            } else{
                $("#more_posts").attr("disabled",true);
            }
        },
        error : function(jqXHR, textStatus, errorThrown) {
            $loader.html(jqXHR + " :: " + textStatus + " :: " + errorThrown);
        }

    });
    return false;
}

$("#more_posts").on("click",function(){ // When btn is pressed.
    $("#more_posts").attr("disabled",true); // Disable the button, temp.
    load_posts();
});

Saved it, tested it, and it works :)

Images as proof (don't mind the shoddy styling, it was done quickly). Also post content is gibberish xD

UPDATE

For 'infinite load' instead on click event on the button (just make it invisible, with visibility: hidden;) you can try with

$(window).on('scroll', function () {
    if ($(window).scrollTop() + $(window).height()  >= $(document).height() - 100) {
        load_posts();
    }
});

This should run the load_posts() function when you're 100px from the bottom of the page. In the case of the tutorial on my site you can add a check to see if the posts are loading (to prevent firing of the ajax twice), and you can fire it when the scroll reaches the top of the footer

$(window).on('scroll', function(){
    if($('body').scrollTop()+$(window).height() > $('footer').offset().top){
        if(!($loader.hasClass('post_loading_loader') || $loader.hasClass('post_no_more_posts'))){
                load_posts();
        }
    }
});

Now the only drawback in these cases is that you could never scroll to the value of $(document).height() - 100 or $('footer').offset().top for some reason. If that should happen, just increase the number where the scroll goes to.

You can easily check it by putting console.logs in your code and see in the inspector what they throw out

$(window).on('scroll', function () {
    console.log($(window).scrollTop() + $(window).height());
    console.log($(document).height() - 100);
    if ($(window).scrollTop() + $(window).height()  >= $(document).height() - 100) {
        load_posts();
    }
});

And just adjust accordingly ;)

Hope this helps :) If you have any questions just ask.

My solution is to create UIView subclass with CAGradientLayer accessible as a readonly property. This will allow you to customize your gradient how you want and you don't need to handle layout changes yourself. Subclass implementation:

@interface GradientView : UIView

@property (nonatomic, readonly) CAGradientLayer *gradientLayer;

@end

@implementation GradientView

+ (Class)layerClass
{
    return [CAGradientLayer class];
}

- (CAGradientLayer *)gradientLayer
{
    return (CAGradientLayer *)self.layer;
}

@end

Usage:

self.iconBackground = [GradientView new];
[self.background addSubview:self.iconBackground];
self.iconBackground.gradientLayer.colors = @[(id)[UIColor blackColor].CGColor, (id)[UIColor whiteColor].CGColor];
self.iconBackground.gradientLayer.startPoint = CGPointMake(1.0f, 1.0f);
self.iconBackground.gradientLayer.endPoint = CGPointMake(0.0f, 0.0f);

you have enlosed start_date with single quote causing it to become string, use backtick instead

SELECT * FROM `la_schedule` WHERE `start_date` > '2012-11-18';

__FUNCTION__ is non standard, __func__ exists in C99 / C++11. The others (__LINE__ and __FILE__) are just fine.

It will always report the right file and line (and function if you choose to use __FUNCTION__/__func__). Optimization is a non-factor since it is a compile time macro expansion; it will never affect performance in any way.

Just to add on Jacek's perfect solution. If you're trying to do this in Kotlin, it wont work immediately. Instead, you'll want to use this:

@Throws(IOException::class)
fun getSplashVideo(context: Context): File {
    val cacheFile = File(context.cacheDir, "splash_video")
    try {
        val inputStream = context.assets.open("splash_video")
        val outputStream = FileOutputStream(cacheFile)
        try {
            inputStream.copyTo(outputStream)
        } finally {
            inputStream.close()
            outputStream.close()
        }
    } catch (e: IOException) {
        throw IOException("Could not open splash_video", e)
    }
    return cacheFile
}

Try to use the rack-cors gem. And add the header field in your Ajax call.

Here is a flexible approach, it can be used in all cases, in particular:

1. to affect only one column, or
2. the dataframe has been obtained from applying previous operations (e.g. not immediately opening a file, or creating a new data frame).

First, un-factorize a string using the as.character function, and, then, re-factorize with the as.factor (or simply factor) function:

fixed <- data.frame("Type" = character(3), "Amount" = numeric(3))

# Un-factorize (as.numeric can be use for numeric values)
#              (as.vector  can be use for objects - not tested)
fixed$Type <- as.character(fixed$Type)
fixed[1, ] <- c("lunch", 100)

# Re-factorize with the as.factor function or simple factor(fixed$Type)
fixed$Type <- as.factor(fixed$Type)

nohup some_command &> nohup2.out &

and voila.

Older syntax for Bash version < 4:

nohup some_command > nohup2.out 2>&1 &

Assign your image to a string. Eg image Now set icon to a fixed size label.

image.setIcon(new javax.swing.ImageIcon(image.getScaledInstance(50,50,WIDTH)));

It was mentioned in the unset manual's page in 2009:

unset() does just what its name says - unset a variable. It does not force immediate memory freeing. PHP's garbage collector will do it when it see fits - by intention as soon, as those CPU cycles aren't needed anyway, or as late as before the script would run out of memory, whatever occurs first.

If you are doing $whatever = null; then you are rewriting variable's data. You might get memory freed / shrunk faster, but it may steal CPU cycles from the code that truly needs them sooner, resulting in a longer overall execution time.

(Since 2013, that unset man page don't include that section anymore)

Note that until php5.3, if you have two objects in circular reference, such as in a parent-child relationship, calling unset() on the parent object will not free the memory used for the parent reference in the child object. (Nor will the memory be freed when the parent object is garbage-collected.) (bug 33595)

The question "difference between unset and = null" details some differences:

unset($a) also removes $a from the symbol table; for example:

$a = str_repeat('hello world ', 100);
unset($a);
var_dump($a);

Outputs:

Notice: Undefined variable: a in xxx
NULL

But when $a = null is used:

$a = str_repeat('hello world ', 100);
$a = null;
var_dump($a);

Outputs:

NULL

It seems that $a = null is a bit faster than its unset() counterpart: updating a symbol table entry appears to be faster than removing it.

• when you try to use a non-existent (unset) variable, an error will be triggered and the value for the variable expression will be null. (Because, what else should PHP do? Every expression needs to result in some value.)
• A variable with null assigned to it is still a perfectly normal variable though.

enter the values as 0:mm:ss and format as [m]:ss

as this is now in the mins & seconds, simple arithmetic will allow you to calculate your statistics

You can do something like this:

// show loading image
$('#loader_img').show();

// main image loaded ?
$('#main_img').on('load', function(){
  // hide/remove the loading image
  $('#loader_img').hide();
});

You assign load event to the image which fires when image has finished loading. Before that, you can show your loader image.

This is all perfectly normal. Microsoft added sequences in SQL Server 2012, finally, i might add and changed the way identity keys are generated. Have a look here for some explanation.

If you want to have the old behaviour, you can:

1. use trace flag 272 - this will cause a log record to be generated for each generated identity value. The performance of identity generation may be impacted by turning on this trace flag.
2. use a sequence generator with the NO CACHE setting (http://msdn.microsoft.com/en-us/library/ff878091.aspx)

If you want to give your user all read permissions, you could use:

EXEC sp_addrolemember N'db_datareader', N'your-user-name'

That adds the default db_datareader role (read permission on all tables) to that user.

There's also a db_datawriter role - which gives your user all WRITE permissions (INSERT, UPDATE, DELETE) on all tables:

EXEC sp_addrolemember N'db_datawriter', N'your-user-name'

If you need to be more granular, you can use the GRANT command:

GRANT SELECT, INSERT, UPDATE ON dbo.YourTable TO YourUserName
GRANT SELECT, INSERT ON dbo.YourTable2 TO YourUserName
GRANT SELECT, DELETE ON dbo.YourTable3 TO YourUserName

and so forth - you can granularly give SELECT, INSERT, UPDATE, DELETE permission on specific tables.

This is all very well documented in the MSDN Books Online for SQL Server.

And yes, you can also do it graphically - in SSMS, go to your database, then Security > Users, right-click on that user you want to give permissions to, then Properties adn at the bottom you see "Database role memberships" where you can add the user to db roles.

Also you can use default() filter. Or just a shortcut d()

If you do <form action="identification" > for your html form, data will be passed using 'Get' by default and hence you can catch this using doGet function in your java servlet code. This way data will be passed under the HTML header and hence will be visible in the URL when submitted. On the other hand if you want to pass data in HTML body, then USE Post: <form action="identification" method="post"> and catch this data in doPost function. This was, data will be passed under the html body and not the html header, and you will not see the data in the URL after submitting the form.

Examples from my html:

<body>  
<form action="StartProcessUrl" method="post">
.....
.....

Examples from my java servlet code:

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated method stub
        PrintWriter out = response.getWriter();
         String surname = request.getParameter("txtSurname");
         String firstname = request.getParameter("txtForename");
         String rqNo = request.getParameter("txtRQ6");
         String nhsNo = request.getParameter("txtNHSNo");

         String attachment1 = request.getParameter("base64textarea1");
         String attachment2 = request.getParameter("base64textarea2");

.........

   By default, flask use a "templates" folder to contain all your template files(any plain-text file, but usually .html or some kind of template language such as jinja2 ) & a "static" folder to contain all your static files(i.e. .js .css and your images).
   In your routes, u can use render_template() to render a template file (as I say above, by default it is placed in the templates folder) as the response for your request. And in the template file (it's usually a .html-like file), u may use some .js and/or `.css' files, so I guess your question is how u link these static files to the current template file.

If you want to cut a string for a specifited length and add dots use

// Length to cut
var lengthToCut = 20;

// Sample text
var text = "The quick brown fox jumps over the lazy dog";

// We are getting 50 letters (0-50) from sample text
var cutted = text.substr(0, lengthToCut );
document.write(cutted+"...");

Or if you want to cut not by length but with words count use:

// Number of words to cut
var wordsToCut = 3;

// Sample text
var text = "The quick brown fox jumps over the lazy dog";

// We are splitting sample text in array of words
var wordsArray = text.split(" ");

// This will keep our generated text
var cutted = "";
for(i = 0; i < wordsToCut; i++)
 cutted += wordsArray[i] + " "; // Add to cutted word with space

document.write(cutted+"...");

Good luck...

The only thing the eclipse plugin is checking is the tomcat version inside:

catalina.jar!/org/apache/catalina/util/ServerInfo.properties

I replaced the properties file with the one in tomcat7 and that fixed the issue for eclipse

In order to be able to deploy the spring-websockets sample app you need to edit the following file in eclipse:

.settings/org.eclipse.wst.common.project.facet.core.xml

And change the web version to 2.5

<installed facet="jst.web" version="2.5"/>

What is the secret key does, you may have already known till now. It is basically HMAC SH256 (Secure Hash). The Secret is a symmetrical key.

Using the same key you can generate, & reverify, edit, etc.

For more secure, you can go with private, public key (asymmetric way). Private key to create token, public key to verify at client level.

Coming to secret key what to give You can give anything, "sudsif", "sdfn2173", any length

you can use online generator, or manually write

I prefer using openssl

C:\Users\xyz\Desktop>openssl rand -base64 12
65JymYzDDqqLW8Eg

generate, then encode with base 64

C:\Users\xyz\Desktop>openssl rand -out openssl-secret.txt -hex 20

The generated value is saved inside the file named "openssl-secret.txt"

generate, & store into a file.

One thing is giving 12 will generate, 12 characters only, but since it is base 64 encoded, it will be (4/3*n) ceiling value.

I recommend reading this article

In "pydot.py" (located in ...\Anaconda3\Lib\site-packages), replace:

def get_executable_extension():
    # type: () -> str
    if is_windows():
        return '.bat' if is_anacoda() else '.exe'
    else:
        return ''

with:

def get_executable_extension():
    # type: () -> str
    if is_windows():
        return '.exe'
    else:
        return ''

There does not seem to be any eason to add ".bat" when the system is "Windows/Anaconda" vs "Windows" and there may be no ".bat" associated with the ".exe". This seems better than adding a ".bat" for every executable pydot calls...

When you want to discard changes in your local branch, you can stash these changes using git stash command.

git stash save "some_name"

Your changes will be saved and you can retrieve those later,if you want or you can delete it. After doing this, your branch will not have any uncommitted code and you can pull the latest code from your main branch using git pull.

An IEnumerator is a thing that can enumerate: it has the Current property and the MoveNext and Reset methods (which in .NET code you probably won't call explicitly, though you could).

An IEnumerable is a thing that can be enumerated...which simply means that it has a GetEnumerator method that returns an IEnumerator.

Which do you use? The only reason to use IEnumerator is if you have something that has a nonstandard way of enumerating (that is, of returning its various elements one-by-one), and you need to define how that works. You'd create a new class implementing IEnumerator. But you'd still need to return that IEnumerator in an IEnumerable class.

For a look at what an enumerator (implementing IEnumerator<T>) looks like, see any Enumerator<T> class, such as the ones contained in List<T>, Queue<T>, or Stack<T>. For a look at a class implementing IEnumerable, see any standard collection class.

Is this what you are looking for? Otherwise, let me know and I will remove this post.

You can use zIndex for placing a view on top of another. It works like the CSS z-index property - components with a larger zIndex will render on top.

I had the same error message, and the problem was also the metadata part of the connection string, but I had to dig a little deeper to solve it and wanted to share this little nugget:

The metadata string is made up of three sections that each look like this:

res://
      (assembly)/
      (model name).(ext)

Where ext is "csdl", "ssdl", and "msl".

For most people, assembly can probably be "*", which seems to indicate that all loaded assemblies will be searched (I haven't done a huge amount of testing of this). This part wasn't an issue for me, so I can't comment on whether you need the assembly name or file name (i.e., with or without ".dll"), though I have seen both suggested.

The model name part should be the name and namespace of your .edmx file, relative to your assembly. So if you have a My.DataAccess assembly and you create DataModels.edmx in a Models folder, its full name is My.DataAccess.Models.DataModels. In this case, you would have "Models.DataModels.(ext)" in your metadata.

If you ever move or rename your .edmx file, you will need to update your metadata string manually (in my experience), and remembering to change the relative namespace will save a few headaches.

As of today, there is no support on this function. However, I found a little hack on this one.

 imageView.setImageResource(R.drawable.ic_star_black_48dp);
 imageView.setTag(R.drawable.ic_star_black_48dp);

So if you want to get the ID of the view, just get it's tag.

if (imageView.getTag() != null) {
   int resourceID = (int) imageView.getTag();

   //
   // drawable id.
   //   
}

Another way this could be accomplished is by using the Start-Transcript and Stop-Transcript commands, respectively before and after command execution. This would capture the entire session including commands.

Start-Transcript

Stop-Transcript

For this particular case Out-File is probably your best bet though.

You can use the eq method or selector:

$('ul').find('li').eq(index).css({'background-color':'#343434'});

Tables work differently; sometimes counter-intuitively.

The solution is to use width on the table cells instead of max-width.

Although it may sound like in that case the cells won't shrink below the given width, they will actually.
with no restrictions on c, if you give the table a width of 70px, the widths of a, b and c will come out as 16, 42 and 12 pixels, respectively.
With a table width of 400 pixels, they behave like you say you expect in your grid above.
Only when you try to give the table too small a size (smaller than a.min+b.min+the content of C) will it fail: then the table itself will be wider than specified.

I made a snippet based on your fiddle, in which I removed all the borders and paddings and border-spacing, so you can measure the widths more accurately.

table {_x000D_
  width: 70px;_x000D_
}_x000D_
_x000D_
table, tbody, tr, td {_x000D_
  margin: 0;_x000D_
  padding: 0;_x000D_
  border: 0;_x000D_
  border-spacing: 0;_x000D_
}_x000D_
_x000D_

  max-width: 45px;_x000D_
}_x000D_
_x000D_
.c {}

  <tr>_x000D_
    <td class="a">A</td>_x000D_

I like the backwards iterator at the end of Yakk - Adam Nevraumont's answer, but it seemed complicated for what I needed, so I wrote this:

template <class T>
class backwards {
    T& _obj;
public:
    backwards(T &obj) : _obj(obj) {}
    auto begin() {return _obj.rbegin();}
    auto end() {return _obj.rend();}
};

I'm able to take a normal iterator like this:

for (auto &elem : vec) {
    // ... my useful code
}

and change it to this to iterate in reverse:

for (auto &elem : backwards(vec)) {
    // ... my useful code
}

I was able to achieve this by using the webkit-line-clamp and the following css:

div {
  display: -webkit-box;
  -webkit-line-clamp: 1;
  -webkit-box-orient: vertical;
  overflow: hidden;
}

In Mysql, We can declare and use variables with set command like below

mysql> set @foo="manjeet";
mysql> select * from table where name = @foo;

First go to android studio folder on location that you installed it ( It’s usually in this path by default ; C:\Program Files\Android\Android Studio, unless you change it when you install Android Studio). Find and run uninstall.exe file.

Wait until uninstallation complete successfully, just few minutes, and after click the close.

To delete any remains of Android Studio setting files, in File Explorer, go to C:\Users\%username%, and delete .android, .AndroidStudio(#version-number) and also .gradle, AndroidStudioProjects if they exist. If you want remain your projects, you’d like to keep AndroidStudioProjects folder.

Then, go to C:\Users\%username%\AppData\Roaming and delete the JetBrains directory.

Note that AppData folder is hidden by default, to make visible it go to view tab and check hidden items in windows8 and10 ( in windows7 Select Folder Options, then select the View tab. Under Advanced settings, select Show hidden files, folders, and drives, and then select OK.

Done, you can remove Android Studio successfully, if you plan to delete SDK tools too, it is enough to remove SDK folder completely.

control+fn+F11 will do. There's no need for "command" key

Now, i'm being told that this will terminate the session (or is it all sessions?) in the 15th minute of use, regardless their activity.

No, that's not true. The session-timeout configures a per session timeout in case of inactivity.

Are these methods equivalent? Should I favour the web.xml config?

The setting in the web.xml is global, it applies to all sessions of a given context. Programatically, you can change this for a particular session.

You can also try this, after injecting $window service.

$window.location.reload();

The code of @ThePracticalOne is great for showing the usage except for one thing: Somtimes the output would be incomplete.(session.recv_ready() turns true after the if session.recv_ready(): while session.recv_stderr_ready() and session.exit_status_ready() turned true before entering next loop)

so my thinking is to retrieving the data when it is ready to exit the session.

while True:
if session.exit_status_ready():
while True:
    while True:
        print "try to recv stdout..."
        ret = session.recv(nbytes)
        if len(ret) == 0:
            break
        stdout_data.append(ret)

    while True:
        print "try to recv stderr..."
        ret = session.recv_stderr(nbytes)
        if len(ret) == 0:
            break
        stderr_data.append(ret)
    break

1. First, remove the current Xcode installation from your machine. You can probably skip this step but I wanted to start fresh. Plus — Xcode was behaving a little weird lately so this is a good opportunity to do that.
2. Install Xcode 8 from the App Store. Make sure project files (.xcodeproj) and workspace files (.xcworkspace) can be opened with the new Xcode installation (remember to select the Later option whenever prompted).
3. Download the Xcode 7.3.1 dmg file from Apple. Double-tap the newly downloaded dmg file in order to get the standard “Drag to install Xcode in your Applications folder”. Don’t do that. Instead, drag the Xcode icon to the desktop. Change the file name to Xcode 7.3.1. Now drag it to the Applications folder.

Now you have two versions of Xcode installed on your machine. Xcode 7.3.1 and Xcode 8.

Details: Install Xcode 7 & Xcode 8 side by side

When starting the JVM, two parameters can be adjusted to suit your memory needs :

-Xms<size>

specifies the initial Java heap size and

-Xmx<size>

the maximum Java heap size.

Question is too old but may be helpful to someone in future. After search many things, most of them is not worked for me. SO, as per my try This solution is worked for me. In short uninstall and install "Android SDK Tools" in Android SDK.

Few steps for that are below:-

1. go to "SDK Manager" in Android Studio
2. go to "SDK Tools" tab
3. Uninstall "Android SDK Tools" (means remove check(uncheck) ahead of "Android SDK Tools" and Apply then OK)
4. Close and Restart Android Studio
5. Install "Android SDK Tools" (means check ahead of "Android SDK Tools" and Apply then OK)

I got around this by upgrading both the version of Angular that I was using (from v8 -> v9) and the version of TypeScript (from 3.5.3 -> latest).

I Did that and it works for redirecting to other view I think If you add the #sectionLink after It will work

<a class="btn yellow" href="/users/Create/@Model.Id" target="_blank">
                                        Add As User
                                    </a>

Say you want to save the string I'm a "foobar" in the database.
Your query will look something like INSERT INTO foos (text) VALUES ("$text").
With the $text variable replaced, this will look like this:

INSERT INTO foos (text) VALUES ("I'm a "foobar"")

Now, where exactly does the string end? You may know, an SQL parser doesn't. Not only will this simply break this query, it can also be abused to inject SQL commands you didn't intend.

mysql_real_escape_string makes sure such ambiguities do not occur by escaping characters which have special meaning to an SQL parser:

mysql_real_escape_string($text)  =>  I\'m a \"foobar\"

This becomes:

INSERT INTO foos (text) VALUES ("I\'m a \"foobar\"")

This makes the statement unambiguous and safe. The \ signals that the following character is not to be taken by its special meaning as string terminator. There are a few such characters that mysql_real_escape_string takes care of.

Escaping is a pretty universal thing in programming languages BTW, all along the same lines. If you want to type the above sentence literally in PHP, you need to escape it as well for the same reasons:

$text = 'I\'m a "foobar"';
// or
$text = "I'm a \"foobar\"";

Changing the datatype to varbinary seems to work the best for me.

I believe sideshowbarker 's answer here has all the info you need to fix this. If your problem is just No 'Access-Control-Allow-Origin' header is present on the response you're getting, you can set up a CORS proxy to get around this. Way more info on it in the linked answer

1. Create a new package.
2. Move your files from the default package to the new one.

I've created an elegant SQLite library written completely in Swift called SwiftData.

Some of its feature are:

• Bind objects conveniently to the string of SQL
• Support for transactions and savepoints
• Inline error handling
• Completely thread safe by default

It provides an easy way to execute 'changes' (e.g. INSERT, UPDATE, DELETE, etc.):

if let err = SD.executeChange("INSERT INTO Cities (Name, Population, IsWarm, FoundedIn) VALUES ('Toronto', 2615060, 0, '1793-08-27')") {
    //there was an error during the insert, handle it here
} else {
    //no error, the row was inserted successfully
}

and 'queries' (e.g. SELECT):

let (resultSet, err) = SD.executeQuery("SELECT * FROM Cities")
if err != nil {
    //there was an error during the query, handle it here
} else {
    for row in resultSet {
        if let name = row["Name"].asString() {
            println("The City name is: \(name)")
        }
        if let population = row["Population"].asInt() {
            println("The population is: \(population)")
        }
        if let isWarm = row["IsWarm"].asBool() {
            if isWarm {
                println("The city is warm")
            } else {
                println("The city is cold")
            }
        }
        if let foundedIn = row["FoundedIn"].asDate() {
            println("The city was founded in: \(foundedIn)")
        }
    }
}

Along with many more features!

[Linqer] is a SQL to LINQ converter tool. It helps you to learn LINQ and convert your existing SQL statements.

Not every SQL statement can be converted to LINQ, but Linqer covers many different types of SQL expressions. Linqer supports both .NET languages - C# and Visual Basic.

Here is how to use UIVibrancyEffect and UIBlurEffect with UIVisualEffectView

Objective-C:

// Blur effect
UIBlurEffect *blurEffect = [UIBlurEffect effectWithStyle:UIBlurEffectStyleDark];
UIVisualEffectView *blurEffectView = [[UIVisualEffectView alloc] initWithEffect:blurEffect];
[blurEffectView setFrame:self.view.bounds];
[self.view addSubview:blurEffectView];

// Vibrancy effect
UIVibrancyEffect *vibrancyEffect = [UIVibrancyEffect effectForBlurEffect:blurEffect];
UIVisualEffectView *vibrancyEffectView = [[UIVisualEffectView alloc] initWithEffect:vibrancyEffect];
[vibrancyEffectView setFrame:self.view.bounds];

// Label for vibrant text
UILabel *vibrantLabel = [[UILabel alloc] init];
[vibrantLabel setText:@"Vibrant"];
[vibrantLabel setFont:[UIFont systemFontOfSize:72.0f]];
[vibrantLabel sizeToFit];
[vibrantLabel setCenter: self.view.center];

// Add label to the vibrancy view
[[vibrancyEffectView contentView] addSubview:vibrantLabel];

// Add the vibrancy view to the blur view
[[blurEffectView contentView] addSubview:vibrancyEffectView];

Swift 4:

    // Blur Effect
    let blurEffect = UIBlurEffect(style: UIBlurEffectStyle.dark)
    let blurEffectView = UIVisualEffectView(effect: blurEffect)
    blurEffectView.frame = view.bounds
    view.addSubview(blurEffectView)

    // Vibrancy Effect
    let vibrancyEffect = UIVibrancyEffect(blurEffect: blurEffect)
    let vibrancyEffectView = UIVisualEffectView(effect: vibrancyEffect)
    vibrancyEffectView.frame = view.bounds

    // Label for vibrant text
    let vibrantLabel = UILabel()
    vibrantLabel.text = "Vibrant"
    vibrantLabel.font = UIFont.systemFont(ofSize: 72.0)
    vibrantLabel.sizeToFit()
    vibrantLabel.center = view.center

    // Add label to the vibrancy view
    vibrancyEffectView.contentView.addSubview(vibrantLabel)

    // Add the vibrancy view to the blur view
    blurEffectView.contentView.addSubview(vibrancyEffectView)

Just use abs(x - y). This'll return the net difference between the two as a positive value, regardless of which value is larger.

I had a same issue on ubuntu 14.04 Here is a solution

sudo service docker start

or you can list images

docker images

Use

datatable.select("col1='test'","col1 ASC")

Then before binding your data to the grid or repeater etc, use this

datatable.defaultview.sort()

That will solve your problem.

open your Redis cli and There two possible option that you could use:

FLUSHDB - Delete all the keys of the currently selected DB. FLUSHALL - Delete all the keys of all the existing databases, not just the currently selected one.

<a href="home.php?click=1" class="btn">Click me</a>
<?php 
  if($_GET['click']){
    doSomething();
  }
?>

But is better to use JS and with ajax to call function!

You can't use IF like that. You can do what you want with AND and OR:

SELECT t.first_name,
       t.last_name,
       t.employid,
       t.status
  FROM employeetable t
 WHERE ((status_flag = STATUS_ACTIVE   AND t.status = 'A')
     OR (status_flag = STATUS_INACTIVE AND t.status = 'T')
     OR (source_flag = SOURCE_FUNCTION AND t.business_unit = 'production')
     OR (source_flag = SOURCE_USER     AND t.business_unit = 'users'))
   AND t.first_name LIKE firstname
   AND t.last_name  LIKE lastname
   AND t.employid   LIKE employeeid;

String whole = "something";
String first = whole.substring(0, 1);
System.out.println(first);

I downloaded Android Studio and installed it. The installer said:-

Android Studio => ( 500 MB )

Android SDK => ( 2.3 GB )

Android Studio installer is actually an "Android SDK Installer" along with a sometimes useful tool called "Android Studio".

Most importantly:- Android Studio Installer will not just install the SDK. It will also:-

• Install the latest build-tools.
• Install the latest platform-tools.
• Install the latest AVD Manager which you cannot do without.

Things which you will have to do manually if you install the SDK from its zip file.

Just take it easy. Install the Android Studio.

****************************** Edit ******************************

So, being inspired by the responses in the comments I would like to update my answer.

The update is that only (and only) if 500MB of hard disk space does not matter much to you than you should go for Android Studio otherwise other answers would be better for you.

Android Studio worked for me as I had a 1TB hard disk which is 2000 times 500MB.

Also, note: that RAM sizse should not a restriction for you as you would not even be running Android Studio.

I came to this solution as I was myself stuck in this problem. I tried other answers but for some reason (maybe my in-competencies) they did not work for me. I decided to go for Android Studio and realized that it was merely 18% of the total installation and SDK was 82% of it. While I used to think otherwise. I am not deleting the answers inspite of negative rating as the answer worked for me. I might work for someone elese with a 1 TB hard disk (which is pretty common these days).

This way of specifying the encoding of a Python file comes from PEP 0263 - Defining Python Source Code Encodings.

It is also recognized by GNU Emacs (see Python Language Reference, 2.1.4 Encoding declarations), though I don't know if it was the first program to use that syntax.

For me what worked is having it like this

style={{ backgroundImage: `url(${require("./resources/img/banners/3.jpg")})` }}

The proper way to remove a cookie is to set the max age to 0 and add the cookie back to the HttpServletResponse object.

Most people don't realize or forget to add the cookie back onto the response object. By doing that it will expire and remove the cookie immediately.

...retrieve cookie from HttpServletRequest
cookie.setMaxAge(0);
response.addCookie(cookie);

The accepted answer is not correct.

isset() is NOT equivalent to !empty().

You will create some rather unpleasant and hard to debug bugs if you go down this route. e.g. try running this code:

<?php

$s = '';

print "isset: '" . isset($s) . "'. ";
print "!empty: '" . !empty($s) . "'";

?>

The below code helps me to return a JSON object for JavaScript on the front end

My template code

template_file.json

{
    "name": "{{name}}"
}

Python backed code

def download_json(request):
    print("Downloading JSON")
    # Response render a template as JSON object
    return HttpResponse(render_to_response("template_file.json",dict(name="Alex Vera")),content_type="application/json")    

File url.py

url(r'^download_as_json/$', views.download_json, name='download_json-url')

jQuery code for the front end

  $.ajax({
        url:'{% url 'download_json-url' %}'        
    }).done(function(data){
        console.log('json ', data);
        console.log('Name', data.name);
        alert('hello ' + data.name);
    });

Just making something more stable :

var keys = [];
$(document).keydown(function (e) { 
    if(e.which == 32 || e.which == 70){
    keys.push(e.which);
    if(keys.length == 2 && keys.indexOf(32) != -1 && keys.indexOf(70) != -1){
        
        
        
        alert("it WORKS !!"); //MAKE SOMETHING HERE---------------->
        
        
        
        keys.length = 0;
    }else if((keys.indexOf(32) == -1 && keys.indexOf(70) != -1) || (keys.indexOf(32) != -1 && keys.indexOf(70) == -1) && (keys.indexOf(32) > 1 || keys.indexOf(70) > 1)){
    }else{
        keys.length = 0;
    }
}else{
    keys.length = 0;
}
});

Renderer has been deprecated in Angular 4.0.0-rc.1, read the update below

The angular2 way is to use listen or listenGlobal from Renderer

For example, if you want to add a click event to a Component, you have to use Renderer and ElementRef (this gives you as well the option to use ViewChild, or anything that retrieves the nativeElement)

constructor(elementRef: ElementRef, renderer: Renderer) {

    // Listen to click events in the component
    renderer.listen(elementRef.nativeElement, 'click', (event) => {
      // Do something with 'event'
    })
);

You can use listenGlobal that will give you access to document, body, etc.

renderer.listenGlobal('document', 'click', (event) => {
  // Do something with 'event'
});

Note that since beta.2 both listen and listenGlobal return a function to remove the listener (see breaking changes section from changelog for beta.2). This is to avoid memory leaks in big applications (see #6686).

So to remove the listener we added dynamically we must assign listen or listenGlobal to a variable that will hold the function returned, and then we execute it.

// listenFunc will hold the function returned by "renderer.listen"
listenFunc: Function;

// globalListenFunc will hold the function returned by "renderer.listenGlobal"
globalListenFunc: Function;

constructor(elementRef: ElementRef, renderer: Renderer) {
    
    // We cache the function "listen" returns
    this.listenFunc = renderer.listen(elementRef.nativeElement, 'click', (event) => {
        // Do something with 'event'
    });

    // We cache the function "listenGlobal" returns
    this.globalListenFunc = renderer.listenGlobal('document', 'click', (event) => {
        // Do something with 'event'
    });
}

ngOnDestroy() {
    // We execute both functions to remove the respectives listeners

    // Removes "listen" listener
    this.listenFunc();
    
    // Removs "listenGlobal" listener
    this.globalListenFunc();
}

Here's a plnkr with an example working. The example contains the usage of listen and listenGlobal.

Using RendererV2 with Angular 4.0.0-rc.1+ ^{_{(Renderer2 since 4.0.0-rc.3)}}

• 25/02/2017: Renderer has been deprecated, now we should use RendererV2 (see line below). See the commit.

• 10/03/2017: RendererV2 was renamed to Renderer2. See the breaking changes.

RendererV2 has no more listenGlobal function for global events (document, body, window). It only has a listen function which achieves both functionalities.

For reference, I'm copy & pasting the source code of the DOM Renderer implementation since it may change (yes, it's angular!).

listen(target: 'window'|'document'|'body'|any, event: string, callback: (event: any) => boolean):
      () => void {
    if (typeof target === 'string') {
      return <() => void>this.eventManager.addGlobalEventListener(
          target, event, decoratePreventDefault(callback));
    }
    return <() => void>this.eventManager.addEventListener(
               target, event, decoratePreventDefault(callback)) as() => void;
  }

As you can see, now it verifies if we're passing a string (document, body or window), in which case it will use an internal addGlobalEventListener function. In any other case, when we pass an element (nativeElement) it will use a simple addEventListener

To remove the listener it's the same as it was with Renderer in angular 2.x. listen returns a function, then call that function.

Example

// Add listeners
let global = this.renderer.listen('document', 'click', (evt) => {
  console.log('Clicking the document', evt);
})

let simple = this.renderer.listen(this.myButton.nativeElement, 'click', (evt) => {
  console.log('Clicking the button', evt);
});

// Remove listeners
global();
simple();

This should work on most databases. You can also select a blank string as your extra column like so:

Select
  Hat, Show, Boat, '' as SomeValue
From
  Objects

Here is an awesome and precise explanation I found.

TIMESTAMP used to track changes of records, and update every time when the record is changed. DATETIME used to store specific and static value which is not affected by any changes in records.

TIMESTAMP also affected by different TIME ZONE related setting. DATETIME is constant.

TIMESTAMP internally converted a current time zone to UTC for storage, and during retrieval convert the back to the current time zone. DATETIME can not do this.

TIMESTAMP is 4 bytes and DATETIME is 8 bytes.

TIMESTAMP supported range: ‘1970-01-01 00:00:01' UTC to ‘2038-01-19 03:14:07' UTC DATETIME supported range: ‘1000-01-01 00:00:00' to ‘9999-12-31 23:59:59'
