Simply because this is the inheritance philosophy. And according to the Java language specification, this is how the constructor's body is defined:

ConstructorBody: { ExplicitConstructorInvocation_opt    BlockStatements_opt }

The first statement of a constructor body may be either

• an explicit invocation of another constructor of the same class (by using the keyword "this"); or
• an explicit invocation of the direct superclass (by using the keyword "super")

If a constructor body does not begin with an explicit constructor invocation and the constructor being declared is not part of the primordial class Object, then the constructor body implicitly begins with a superclass constructor invocation "super();", an invocation of the constructor of its direct superclass that takes no arguments. And so on.. there will be a whole chain of constructors called all the way back to the constructor of Object; "All Classes in the Java platform are Descendants of Object". This thing is called "Constructor Chaining".

Now why is this?
And the reason why Java defined the ConstructorBody in this way, is that they needed to maintain the hierarchy of the object. Remember the definition of the inheritance; It's extending a class. With that being said, you cannot extend something that doesn't exist. The base (the superclass) needs to be created first, then you can derive it (the subclass). That's why they called them Parent and Child classes; you can't have a child without a parent.

On a technical level, a subclass inherits all the members (fields, methods, nested classes) from its parent. And since Constructors are NOT members (They don't belong to objects. They are responsible of creating objects) so they are NOT inherited by subclasses, but they can be invoked. And since at the time of object creation only ONE constructor is executed. So how do we guarantee the creation of the superclass when you create the subclass object? Thus the concept of "constructor chaining"; so we have the ability to invoke other constructors (i.e. super) from within the current constructor. And Java required this invocation to be the FIRST line in the subclass constructor to maintain the hierarchy and guarantee it. They assume that if you don't explicitly create the parent object FIRST (like if you forgot about it), they will do it implicitly for you.

This check is done during compilation. But I'm not sure what would happen on runtime, what kind of runtime error we would get, IF Java doesn't throw a compile-error when we explicitly try to execute a base constructor from within a subclass's constructor in the middle of its body and not from the very first line ...

If you used Create React App, you can set an environment variable using a .env file. The documentation is here:

https://facebook.github.io/create-react-app/docs/adding-custom-environment-variables

Basically do something like this in the .env file at the project root.

REACT_APP_NOT_SECRET_CODE=abcdef

Note that the variable name must start with REACT_APP_

You can access it from your component with

process.env.REACT_APP_NOT_SECRET_CODE

You don't need to learn JPA. You can use my easy-criteria for JPA2 (https://sourceforge.net/projects/easy-criteria/files/). Here is the example

CriteriaComposer<Pet> petCriteria CriteriaComposer.from(Pet.class).
where(Pet_.type, EQUAL, "Cat").join(Pet_.owner).where(Ower_.name,EQUAL, "foo");

List<Pet> result = CriteriaProcessor.findAllEntiry(petCriteria);

OR

List<Tuple> result =  CriteriaProcessor.findAllTuple(petCriteria);

Here is a good tutorial with code. Let me know if it works for you! This is also a good tutorial.

EDIT

In This example, all you need to do is add this line:

gallery.setSelection(1);

after setting the adapter to gallery object, that is this line:

gallery.setAdapter(new ImageAdapter(this));

UPDATE1

Alright, I got your problem. This open source library is your solution. I also have used it for one of my projects. Hope this will solve your problem finally.

UPDATE2:

I would suggest you to go through this tutorial. You might get idea. I think I got your problem, you want the horizontal scrollview with snap. Try to search with that keyword on google or out here, you might get your solution.

Is the actual problem that you just don't want it to have focus at all? Or you don't want it to show the virtual keyboard as a result of focusing the EditText? I don't really see an issue with the EditText having focus on start, but it's definitely a problem to have the softInput window open when the user did not explicitly request to focus on the EditText (and open the keyboard as a result).

If it's the problem of the virtual keyboard, see the AndroidManifest.xml <activity> element documentation.

android:windowSoftInputMode="stateHidden" - always hide it when entering the activity.

or android:windowSoftInputMode="stateUnchanged" - don't change it (e.g. don't show it if it isn't already shown, but if it was open when entering the activity, leave it open).

function el(id) {
  return document.getElementById(id);
}

if (el('one') || el('two') || el('three')) { 
  alert('yes');

} else if (el('four')) {
  alert('no');
}

Because another class could extend it, and the child class needs to invoke a superclass constructor.

maybe you need to make

hash -r 

it helps with problem of symlink

$ node -v

I'm posting this here, because I've spent like 3 and 4 hours on it, and I've only found answers like those one above, that say do add the executionTime, but it doesn't solve the problem in the case that you're using ASP .NET Core. For it, this would work:

At web.config file, add the requestTimeout attribute at aspNetCore node.

<system.webServer>
  <aspNetCore requestTimeout="00:10:00" ... (other configs goes here) />
</system.webServer>

In this example, I'm setting the value for 10 minutes.

See the abc module. Basically, you define __metaclass__ = abc.ABCMeta on the class, then decorate each abstract method with @abc.abstractmethod. Classes derived from this class cannot then be instantiated unless all abstract methods have been overridden.

If your class is already using a metaclass, derive it from ABCMeta rather than type and you can continue to use your own metaclass.

A cheap alternative (and the best practice before the abc module was introduced) would be to have all your abstract methods just raise an exception (NotImplementedError is a good one) so that classes derived from it would have to override that method to be useful.

However, the abc solution is better because it keeps such classes from being instantiated at all (i.e., it "fails faster"), and also because you can provide a default or base implementation of each method that can be reached using the super() function in derived classes.

If, like me, you had dynamically created buttons on your page, the

$("#your-bs-button's-id").on("click", function(event) {
                       or
$(".your-bs-button's-class").on("click", function(event) {

methods won't work because they only work on current elements (not future elements). Instead you need to reference a parent item that existed at the initial loading of the web page.

$(document).on("click", "#your-bs-button's-id", function(event) {
                       or more generally
$("#pre-existing-element-id").on("click", ".your-bs-button's-class", function(event) {

Seems bundler can't use .gem files out of the box. Pointing the :path to a directory containing .gem files doesn't work. Some people suggested to setup a local gem server (geminabox, stickler) for that purpose.

However, what I found to be much simpler is to use a local gem "server" from file system: Just put your .gem files in a local directory, then use "gem generate_index" to make it a Gem repository

mkdir repo
mkdir repo/gems
cp *.gem repo/gems
cd repo
gem generate_index

Finally point bundler to this location by adding the following line to your Gemfile

source "file://path/to/repo"

If you update the gems in the repository, make sure to regenerate the index.

Today I installed Wamp server 3.0.6 (x64) on a Windows 10 machine with VS2017 installed. I had many Visual C++ Redistributable Packages installed, but not the 2012 one. Then I installed it and now I can run the Wamp server. You can find a download link here.

All of above can be avoided by simply declaring a friend value for runtime on the starting form.

In your expected output, you've got the second last row sum incorrect, it should be 40 according to the data in your tables, but here is the query:

Select  ChargeNum, CategoryId, Sum(Hours)
From    (
    Select  ChargeNum, CategoryId, Hours
    From    KnownHours
    Union
    Select  ChargeNum, 'Unknown' As CategoryId, Hours
    From    UnknownHours
) As a
Group By ChargeNum, CategoryId
Order By ChargeNum, CategoryId

And here is the output:

ChargeNum  CategoryId 
---------- ---------- ----------------------
111111     1          40
111111     2          50
111111     Unknown    70
222222     1          40
222222     Unknown    25.5

For me worked this one:

|([\'"])(.*?)\1|i

I've used in a sentence like this one:

preg_match_all('|([\'"])(.*?)\1|i', $cont, $matches);

and it worked great.

You can move your files to other folder and then pull whole folder.

adb shell mkdir /sdcard/tmp
adb shell mv /sdcard/mydir/*.jpg /sdcard/tmp # move your jpegs to temporary dir
adb pull /sdcard/tmp/ # pull this directory (be sure to put '/' in the end)
adb shell mv /sdcard/tmp/* /sdcard/mydir/ # move them back
adb shell rmdir /sdcard/tmp # remove temporary directory

Axtavt answer is correct.

This is how your resolver should look like (annotations based):

    @Bean
UrlBasedViewResolver resolver(){
    UrlBasedViewResolver resolver = new UrlBasedViewResolver();

    resolver.setPrefix("/views/");
    resolver.setSuffix(".jsp");
    resolver.setViewClass(JstlView.class);

    return resolver;
}

Obviously the name of your views directory should change based on your project.

If anyone still looking for an answer to this issue. For me it happens when I'm switching between local and production server and I'm logged on both sites. To fix the issue, just clear the session.

just set the 'expire_on_close' => true in config\session.php and restart your browser

XPath queries are case sensitive. Having looked at your example (which, by the way, is awesome, nobody seems to provide examples anymore!), I can get the result you want just by changing "business", to "Business"

//production[not(contains(category,'Business'))]

I have tested this by opening the XML file in Chrome, and using the Developer tools to execute that XPath queries, and it gave me just the Film category back.

If You Are Able to Edit the Offending Stylesheet

If the user-agent stylesheet's style is causing problems for the browser it's supposed to fix, then you could try removing the offending style and testing that to ensure it doesn't have any unexpected adverse effects elsewhere.

If it doesn't, use the modified stylesheet. Fixing browser quirks is what these sheets are for - they fix issues, they aren't supposed to introduce new ones.

If You Are Not Able to Edit the Offending Stylesheet

If you're unable to edit the stylesheet that contains the offending line, you may consider using the !important keyword.

An example:

.override {
    border: 1px solid #000 !important;
}

.a_class {
    border: 2px solid red;
}

And the HTML:

<p class="a_class">content will have 2px red border</p>
<p class="override a_class">content will have 1px black border</p>

Live example

Try to use !important only where you really have to - if you can reorganize your styles such that you don't need it, this would be preferable.

foreach (DataTable table in ds.Tables)
{
    foreach (DataRow dr in table.Rows)
    {
        var ParentId=dr["ParentId"].ToString();
    }
}

I observed this issue while using Eclipse. I needed to add encoding in my pom.xml file and it resolved. http://ctrlaltsolve.blogspot.in/2015/11/encoding-properties-in-maven.html

You can create button in a simple way, such as:

Button button = new Button();
button.Click += new EventHandler(button_Click);

protected void button_Click (object sender, EventArgs e)
{
    Button button = sender as Button;
    // identify which button was clicked and perform necessary actions
}

But event probably will not fire, because the element/elements must be recreated at every postback or you will lose the event handler.

I tried this solution that verify that ViewState is already Generated and recreate elements at every postback,

for example, imagine you create your button on an event click:

    protected void Button_Click(object sender, EventArgs e)
    {
       if (Convert.ToString(ViewState["Generated"]) != "true")
        {
            CreateDynamicElements();
        }
    
    }

on postback, for example on page load, you should do this:

    protected void Page_Load(object sender, EventArgs e)
    {
        if (Convert.ToString(ViewState["Generated"]) == "true") {
            CreateDynamicElements();
        }
    }

In CreateDynamicElements() you can put all the elements you need, such as your button.

This worked very well for me.

public void CreateDynamicElements(){

    Button button = new Button();
    button.Click += new EventHandler(button_Click);

}

(Update) V5.1 & Hooks (Requires React >= 16.8)

You can use useHistory, useLocation and useRouteMatch in your component to get match, history and location .

const Child = () => {
  const location = useLocation();
  const history = useHistory();
  const match = useRouteMatch("write-the-url-you-want-to-match-here");

  return (
    <div>{location.pathname}</div>
  )
}

export default Child

(Update) V4 & V5

You can use withRouter HOC in order to inject match, history and location in your component props.

class Child extends React.Component {
  static propTypes = {
    match: PropTypes.object.isRequired,
    location: PropTypes.object.isRequired,
    history: PropTypes.object.isRequired
  }

  render() {
    const { match, location, history } = this.props

    return (
      <div>{location.pathname}</div>
    )
  }
}

export default withRouter(Child)

(Update) V3

You can use withRouter HOC in order to inject router, params, location, routes in your component props.

class Child extends React.Component {

  render() {
    const { router, params, location, routes } = this.props

    return (
      <div>{location.pathname}</div>
    )
  }
}

export default withRouter(Child)

Original answer

If you don't want to use the props, you can use the context as described in React Router documentation

First, you have to set up your childContextTypes and getChildContext

class App extends React.Component{

  getChildContext() {
    return {
      location: this.props.location
    }
  }

  render() {
    return <Child/>;
  }
}

App.childContextTypes = {
    location: React.PropTypes.object
}

Then, you will be able to access to the location object in your child components using the context like this

class Child extends React.Component{

   render() {
     return (
       <div>{this.context.location.pathname}</div>
     )
   }

}

Child.contextTypes = {
    location: React.PropTypes.object
 }

You can print in simple way.

Use below to print 2D array

int[][] array = new int[rows][columns];
System.out.println(Arrays.deepToString(array));

Use below to print 1D array

int[] array = new int[size];
System.out.println(Arrays.toString(array));

For those who are looking just for spaces between items in the RecyclerView see my approach where you get equal spaces between all items, except in first and last items where I gave a bigger padding. I only apply padding to left/right in horizontal LayoutManager and to top/bottom in vertical LayoutManager.

public class PaddingItemDecoration extends RecyclerView.ItemDecoration {

    private int mPaddingPx;
    private int mPaddingEdgesPx;

    public PaddingItemDecoration(Activity activity) {
        final Resources resources = activity.getResources();
        mPaddingPx = (int) resources.getDimension(R.dimen.paddingItemDecorationDefault);
        mPaddingEdgesPx = (int) resources.getDimension(R.dimen.paddingItemDecorationEdge);
    }

    @Override
    public void getItemOffsets(Rect outRect, View view, RecyclerView parent, RecyclerView.State state) {
        super.getItemOffsets(outRect, view, parent, state);

        final int itemPosition = parent.getChildAdapterPosition(view);
        if (itemPosition == RecyclerView.NO_POSITION) {
            return;
        }
        int orientation = getOrientation(parent);
        final int itemCount = state.getItemCount();

        int left = 0;
        int top = 0;
        int right = 0;
        int bottom = 0;

        /** HORIZONTAL */
        if (orientation == LinearLayoutManager.HORIZONTAL) {
            /** all positions */
            left = mPaddingPx;
            right = mPaddingPx;

            /** first position */
            if (itemPosition == 0) {
                left += mPaddingEdgesPx;
            }
            /** last position */
            else if (itemCount > 0 && itemPosition == itemCount - 1) {
                right += mPaddingEdgesPx;
            }
        }
        /** VERTICAL */
        else {
            /** all positions */
            top = mPaddingPx;
            bottom = mPaddingPx;

            /** first position */
            if (itemPosition == 0) {
                top += mPaddingEdgesPx;
            }
            /** last position */
            else if (itemCount > 0 && itemPosition == itemCount - 1) {
                bottom += mPaddingEdgesPx;
            }
        }

        if (!isReverseLayout(parent)) {
            outRect.set(left, top, right, bottom);
        } else {
            outRect.set(right, bottom, left, top);
        }
    }

    private boolean isReverseLayout(RecyclerView parent) {
        if (parent.getLayoutManager() instanceof LinearLayoutManager) {
            LinearLayoutManager layoutManager = (LinearLayoutManager) parent.getLayoutManager();
            return layoutManager.getReverseLayout();
        } else {
            throw new IllegalStateException("PaddingItemDecoration can only be used with a LinearLayoutManager.");
        }
    }

    private int getOrientation(RecyclerView parent) {
        if (parent.getLayoutManager() instanceof LinearLayoutManager) {
            LinearLayoutManager layoutManager = (LinearLayoutManager) parent.getLayoutManager();
            return layoutManager.getOrientation();
        } else {
            throw new IllegalStateException("PaddingItemDecoration can only be used with a LinearLayoutManager.");
        }
    }
}

Details

The other answers use outmoded or incorrect classes.

Avoid the old date-time classes such as java.util.Date/.Calendar. They have proven to be poorly designed, confusing, and troublesome.

java.time

The java.time framework comes built into Java 8 and later. Much of the functionality is backported to Java 6 & 7 and further adapted to Android. Made by the some of the same folks as had made Joda-Time.

An Instant is a moment on the timeline in UTC with a resolution of nanoseconds. Its epoch is first moment of 1970 in UTC.

Assuming your input data is a count of milliseconds from 1970-01-01T00:00:00Z (not clear in the Question), then we can easily instantiate an Instant.

Instant instant = Instant.ofEpochMilli( 1_322_018_752_992L );

instant.toString(): 2011-11-23T03:25:52.992Z

The Z in that standard ISO 8601 formatted string is short for Zulu and means UTC.

Apply a time zone using a proper time zone name, to get a ZonedDateTime.

ZoneId zoneId = ZoneId.of( "Asia/Kolkata" ) ;
ZonedDateTime zdt = instant.atZone( zoneId );

See this code run live at IdeOne.com.

Asia/Kolkata time zone ?

I am guessing your are had an India time zone affecting your code. We see here that adjusting into Asia/Kolkata time zone renders the same time-of-day as you report, 08:55 which is five and a half hours ahead of our UTC value 03:25.

2011-11-23T08:55:52.992+05:30[Asia/Kolkata]

Default zone

You can apply the current default time zone of the JVM. Beware that the default can change at any moment during runtime. Any code in any thread of any app within the JVM can change the current default. If important, ask the user for their desired/expected time zone.

ZoneId zoneId = ZoneId.systemDefault();
ZonedDateTime zdt = ZonedDateTime.ofInstant( instant , zoneId );

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

With a JDBC driver complying with JDBC 4.2 or later, you may exchange java.time objects directly with your database. No need for strings or java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android, the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

Here is example given which so how to use open and "python close

from sys import argv
script,filename=argv
txt=open(filename)
print "filename %r" %(filename)
print txt.read()
txt.close()
print "Change the file name"
file_again=raw_input('>')
print "New file name %r" %(file_again)
txt_again=open(file_again)
print txt_again.read()
txt_again.close()

It's necessary to how many times you opened file have to close that times.

Since the old accepted answer got deleted (It was a link to a Google code search results that no longer exist), I figured I could answer this question for future reference :

public static DateTime GetNetworkTime()
{
    //default Windows time server
    const string ntpServer = "time.windows.com";

    // NTP message size - 16 bytes of the digest (RFC 2030)
    var ntpData = new byte[48];

    //Setting the Leap Indicator, Version Number and Mode values
    ntpData[0] = 0x1B; //LI = 0 (no warning), VN = 3 (IPv4 only), Mode = 3 (Client Mode)

    var addresses = Dns.GetHostEntry(ntpServer).AddressList;

    //The UDP port number assigned to NTP is 123
    var ipEndPoint = new IPEndPoint(addresses[0], 123);
    //NTP uses UDP

    using(var socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp))
    {
        socket.Connect(ipEndPoint);

        //Stops code hang if NTP is blocked
        socket.ReceiveTimeout = 3000;     

        socket.Send(ntpData);
        socket.Receive(ntpData);
        socket.Close();
    }

    //Offset to get to the "Transmit Timestamp" field (time at which the reply 
    //departed the server for the client, in 64-bit timestamp format."
    const byte serverReplyTime = 40;

    //Get the seconds part
    ulong intPart = BitConverter.ToUInt32(ntpData, serverReplyTime);

    //Get the seconds fraction
    ulong fractPart = BitConverter.ToUInt32(ntpData, serverReplyTime + 4);

    //Convert From big-endian to little-endian
    intPart = SwapEndianness(intPart);
    fractPart = SwapEndianness(fractPart);

    var milliseconds = (intPart * 1000) + ((fractPart * 1000) / 0x100000000L);

    //**UTC** time
    var networkDateTime = (new DateTime(1900, 1, 1, 0, 0, 0, DateTimeKind.Utc)).AddMilliseconds((long)milliseconds);

    return networkDateTime.ToLocalTime();
}

// stackoverflow.com/a/3294698/162671
static uint SwapEndianness(ulong x)
{
    return (uint) (((x & 0x000000ff) << 24) +
                   ((x & 0x0000ff00) << 8) +
                   ((x & 0x00ff0000) >> 8) +
                   ((x & 0xff000000) >> 24));
}

Note: You will have to add the following namespaces

using System.Net;
using System.Net.Sockets;

See this: Spring @PropertySource using YAML

I think the 3rd answer has what you're looking for, i.e have a separate POJO to map your yaml values into:

@ConfigurationProperties(path="classpath:/appprops.yml", name="db")
public class DbProperties {
    private String url;
    private String username;
    private String password;
...
}

Then annotate your test class with this:

@EnableConfigurationProperties(DbProperties.class)
public class PropertiesUsingService {

    @Autowired private DbProperties dbProperties;

}

@Nickparsa … you have 2 issues:

1). mysql -uroot -p should be typed in bash (also known as your terminal) not in MySQL command-line. You fix this error by typing

exit

in your MySQL command-line. Now you are back in your bash/terminal command-line.

2). You have a syntax error:

mysql -uroot -p; 

the semicolon in front of -p needs to go. The correct syntax is:

mysql -uroot -p

type the correct syntax in your bash commandline. Enter a password if you have one set up; else just hit the enter button. You should get a response that is similar to this:

Hope this helps!

What's the difference between Perl's backticks (`), system, and exec?

exec -> exec "command"; ,
system -> system("command"); and 
backticks -> print `command`;

exec

exec executes a command and never resumes the Perl script. It's to a script like a return statement is to a function.

If the command is not found, exec returns false. It never returns true, because if the command is found, it never returns at all. There is also no point in returning STDOUT, STDERR or exit status of the command. You can find documentation about it in perlfunc, because it is a function.

E.g.:

#!/usr/bin/perl
print "Need to start exec command";
my $data2 = exec('ls');
print "Now END exec command";
print "Hello $data2\n\n";

In above code, there are three print statements, but due to exec leaving the script, only the first print statement is executed. Also, the exec command output is not being assigned to any variable.

Here, only you're only getting the output of the first print statement and of executing the ls command on standard out.

system

system executes a command and your Perl script is resumed after the command has finished. The return value is the exit status of the command. You can find documentation about it in perlfunc.

E.g.:

#!/usr/bin/perl
print "Need to start system command";
my $data2 = system('ls');
print "Now END system command";
print "Hello $data2\n\n";

In above code, there are three print statements. As the script is resumed after the system command, all three print statements are executed.

Also, the result of running system is assigned to data2, but the assigned value is 0 (the exit code from ls).

Here, you're getting the output of the first print statement, then that of the ls command, followed by the outputs of the final two print statements on standard out.

backticks (`)

Like system, enclosing a command in backticks executes that command and your Perl script is resumed after the command has finished. In contrast to system, the return value is STDOUT of the command. qx// is equivalent to backticks. You can find documentation about it in perlop, because unlike system and exec, it is an operator.

E.g.:

#!/usr/bin/perl
print "Need to start backticks command";
my $data2 = `ls`;
print "Now END system command";
print "Hello $data2\n\n";

In above code, there are three print statements and all three are being executed. The output of ls is not going to standard out directly, but assigned to the variable data2 and then printed by the final print statement.

If you want to delete same effect in input, you could add the following code as well as button.

input:focus {outline:0;}

If you want to change a color to single column try this:

 dataGridView1.EnableHeadersVisualStyles = false;
 dataGridView1.Columns[0].HeaderCell.Style.BackColor = Color.Magenta;
 dataGridView1.Columns[1].HeaderCell.Style.BackColor = Color.Yellow;

Python 2:

import urlparse
url = 'http://foo.appspot.com/abc?def=ghi'
parsed = urlparse.urlparse(url)
print urlparse.parse_qs(parsed.query)['def']

Python 3:

import urllib.parse as urlparse
from urllib.parse import parse_qs
url = 'http://foo.appspot.com/abc?def=ghi'
parsed = urlparse.urlparse(url)
print(parse_qs(parsed.query)['def'])

parse_qs returns a list of values, so the above code will print ['ghi'].

Here's the Python 3 documentation.

You can list the tags on remote repository with ls-remote, and then check if it's there. Supposing the remote reference name is origin in the following.

git ls-remote --tags origin

And you can list tags local with tag.

git tag

You can compare the results manually or in script.

One more code sample to showcase this:

void Main()
{


    int k = 0;
    TestPlain(k);
    Console.WriteLine("TestPlain:" + k);

    TestRef(ref k);
    Console.WriteLine("TestRef:" + k);

    string t = "test";

    TestObjPlain(t);
    Console.WriteLine("TestObjPlain:" +t);

    TestObjRef(ref t);
    Console.WriteLine("TestObjRef:" + t);
}

public static void TestPlain(int i)
{
    i = 5;
}

public static void TestRef(ref int i)
{
    i = 5;
}

public static void TestObjPlain(string s)
{
    s = "TestObjPlain";
}

public static void TestObjRef(ref string s)
{
    s = "TestObjRef";
}

And the output:

TestPlain:0

TestRef:5

TestObjPlain:test

TestObjRef:TestObjRef

Sorry for coding with Kotlin. But I faced the same problem. I solved with the code below.

list.setOnItemClickListener{ _, view, _, _ ->
        val text1 = view.find<TextView>(R.id.~~).text

        }

You can put an id which shows a TextView that you want in "~~".

Hope it'll help someone!

Yes, std::vector stores copies. How should vector know what the expected life-times of your objects are?

If you want to transfer or share ownership of the objects use pointers, possibly smart pointers like shared_ptr (found in Boost or TR1) to ease resource management.

overflow:hidden 

does not always mean that the element is hidden or non existent in the DOM, it means that the overflowing chars that do not fit in the element are being trimmed. Basically it means that do not show scrollbar even if it should be showed, so in your case the link with text

Plastic Spiral Bind

could possibly be shown as "Plastic Spir..." or similar. So it is possible, that this linkText indeed is non existent.

So you can probably try:

driver.findElement(By.partialLinkText("Plastic ")).click();

or xpath:

//a[contains(@title, \"Plastic Spiral Bind\")]

I know you don't want to obfuscate, but maybe you should check out dotfuscator, it will take your compiled assemblies and obfuscate them for you. I think it can even encrypt them.

Use a QR library like ZXing... I had very good experience with it, QrDroid is much buggier. If you must rely on an external reader, rely on a standard one like Google Goggles!

How about just chaining the greps?

grep -n 'loom' ~/projects/**/trunk/src/**/*.@(h|cpp) | grep -v 'gloom'

If you want to use Unix shell commands on Windows, you can use Windows Powershell, which includes both Windows and Unix commands as aliases. You can find more info on it in the documentation.

PowerShell supports aliases to refer to commands by alternate names. Aliasing allows users with experience in other shells to use common command names that they already know for similar operations in PowerShell.

The PowerShell equivalents may not produce identical results. However, the results are close enough that users can do work without knowing the PowerShell command name.

Try this:

$(".datepicker").on("dp.change", function(e) {
    alert('hey');
});

When you scheduled task, just select "Run whether user is logged on or not" under the "General" tab.

Alternate way is to let the task run as another user.

If you are writing in C++ -- it is a way better to use data structures from standard library such as vector.

C-style arrays are very error-prone, and should be avoided whenever possible.

Going down your list:

• "Unicode" isn't an encoding, although unfortunately, a lot of documentation imprecisely uses it to refer to whichever Unicode encoding that particular system uses by default. On Windows and Java, this often means UTF-16; in many other places, it means UTF-8. Properly, Unicode refers to the abstract character set itself, not to any particular encoding.
• UTF-16: 2 bytes per "code unit". This is the native format of strings in .NET, and generally in Windows and Java. Values outside the Basic Multilingual Plane (BMP) are encoded as surrogate pairs. These used to be relatively rarely used, but now many consumer applications will need to be aware of non-BMP characters in order to support emojis.
• UTF-8: Variable length encoding, 1-4 bytes per code point. ASCII values are encoded as ASCII using 1 byte.
• UTF-7: Usually used for mail encoding. Chances are if you think you need it and you're not doing mail, you're wrong. (That's just my experience of people posting in newsgroups etc - outside mail, it's really not widely used at all.)
• UTF-32: Fixed width encoding using 4 bytes per code point. This isn't very efficient, but makes life easier outside the BMP. I have a .NET Utf32String class as part of my MiscUtil library, should you ever want it. (It's not been very thoroughly tested, mind you.)
• ASCII: Single byte encoding only using the bottom 7 bits. (Unicode code points 0-127.) No accents etc.
• ANSI: There's no one fixed ANSI encoding - there are lots of them. Usually when people say "ANSI" they mean "the default locale/codepage for my system" which is obtained via Encoding.Default, and is often Windows-1252 but can be other locales.

There's more on my Unicode page and tips for debugging Unicode problems.

The other big resource of code is unicode.org which contains more information than you'll ever be able to work your way through - possibly the most useful bit is the code charts.

The user-agent should be specified as a field in the header.

Here is a list of HTTP header fields, and you'd probably be interested in request-specific fields, which includes User-Agent.

If you're using requests v2.13 and newer

The simplest way to do what you want is to create a dictionary and specify your headers directly, like so:

import requests

url = 'SOME URL'

headers = {
    'User-Agent': 'My User Agent 1.0',
    'From': '[email protected]'  # This is another valid field
}

response = requests.get(url, headers=headers)

If you're using requests v2.12.x and older

Older versions of requests clobbered default headers, so you'd want to do the following to preserve default headers and then add your own to them.

import requests

url = 'SOME URL'

# Get a copy of the default headers that requests would use
headers = requests.utils.default_headers()

# Update the headers with your custom ones
# You don't have to worry about case-sensitivity with
# the dictionary keys, because default_headers uses a custom
# CaseInsensitiveDict implementation within requests' source code.
headers.update(
    {
        'User-Agent': 'My User Agent 1.0',
    }
)

response = requests.get(url, headers=headers)

You have to put your main queue dispatching in the block that runs the computation. For example (here I create a dispatch queue and don't use a global one):

dispatch_queue_t queue = dispatch_queue_create("com.example.MyQueue", NULL);
dispatch_async(queue, ^{
  // Do some computation here.

  // Update UI after computation.
  dispatch_async(dispatch_get_main_queue(), ^{
    // Update the UI on the main thread.
  });
});

Of course, if you create a queue don't forget to dispatch_release if you're targeting an iOS version before 6.0.

you can throw as object

throw ({message: 'This Failed'})

then for example in your try/catch

try {
//
} catch(e) {
    console.log(e); //{message: 'This Failed'}
    console.log(e.message); //This Failed
}

or just throw a string error

throw ('Your error')

try {
//
} catch(e) {
    console.log(e); //Your error
}

throw new Error //only accept a string

we must also need to add following in build.gradle(app)

compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:design:23.1.1'

whenever we are using new layouts or new design features. hope this helps you.

Following the exceedingly simple method from Andralor here fixed the issue for me: https://github.com/fancyapps/fancyBox/issues/766

Essentially, call the iframe again onUpdate:

$('a.js-fancybox-iframe').fancybox({
    type: 'iframe',
    scrolling : 'visible',
    autoHeight: true,
    onUpdate: function(){
     $("iframe.fancybox-iframe");
   }
 });

From the man page:

-i When a script is passed as first argument or the -c option is used, enter interactive mode after executing the script or the command. It does not read the $PYTHONSTARTUP file. This can be useful to inspect global variables or a stack trace when a script raises an exception.

So this should do what you want:

python -i file.py

One can use runner package for moving functions. In this case mean_run function. Problem with cummean is that it doesn't handle NA values, but mean_run does. runner package also supports irregular time series and windows can depend on date:

set.seed(11)
x1 <- rnorm(15)
x2 <- sample(c(rep(NA,5), rnorm(15)), 15, replace = TRUE)

First off, I know this is an old post, but it is still relevant, and I found that the two highest voted answers did not detect the shake as early as possible. This is how to do it:

1. Link CoreMotion to your project in the target's build phases:

2. In your ViewController:

   - (BOOL)canBecomeFirstResponder {
       return YES;
   }
   
   - (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event
   {
       if (motion == UIEventSubtypeMotionShake) {
           // Shake detected.
       }
   }
   

As others have noted, in general use the -v flag for the gem install command.

If you're developing a gem locally, after cutting a gem from your gemspec:

$ gem install gemname-version.gem

Assuming version 0.8, it would look like this:

$ gem install gemname-0.8.gem

into

For me it was a fresh NetCore application that was just not loading via IIS. When run standalone it was OK though.

I removed the <aspNetCore line and then I got a normal error message from IIS saying that NetCoreModule could not be loaded. That module is required to understand this new web.config line.

The error message 0x8007000d actually says that the web.config is malformed and that error shows up before the error loading module making this error message really crap. (and an unfortunate race condition problem)

I installed the NetCoreSDK and stopped and started IIS (restart didnt work)

The NetCore API started working via IIS as expected.

import os

destdir = '/var/tmp/testdir'

files = [ f for f in os.listdir(destdir) if os.path.isfile(os.path.join(destdir,f)) ]

    [HttpGet]
    public RedirectResult Get()
    {
        return RedirectPermanent("https://www.google.com");
    }

Use SelectList to bind @HtmlDropdownListFor and specify selectedValue parameter in it.

http://msdn.microsoft.com/en-us/library/dd492553(v=vs.108).aspx

Example : you can do like this for getting venderid

@Html.DropDownListFor(m => m.VendorId,Model.Vendor)


   public class MobileViewModel 
   {          
    public List<tbInsertMobile> MobileList;
    public SelectList Vendor { get; set; }
    public int VenderID{get;set;}
   }
   [HttpPost]
   public ActionResult Action(MobileViewModel model)
   {
            var Id = model.VenderID;

For those who want to do this in pure javascript, look at:

Using standard KeyboardEvent

As Joe comment it, KeyboardEvent is now the standard.

Same example to fire an enter (keyCode 13):

const ke = new KeyboardEvent('keydown', {
    bubbles: true, cancelable: true, keyCode: 13
});
document.body.dispatchEvent(ke);

You can use this page help you to find the right keyboard event.

Outdated answer:

• initKeyboardEvent for IE9+, Chrome and Safari
• initKeyEvent for Firefox

You can do something like (here for Firefox)

var ev = document.createEvent('KeyboardEvent');
// Send key '13' (= enter)
ev.initKeyEvent(
    'keydown', true, true, window, false, false, false, false, 13, 0);
document.body.dispatchEvent(ev);

None of the above methods worked for me. If you are on Windows, try this on PyCharm terminal:

setx YOUR_VAR "VALUE"

You can access it in your scripts using os.environ['YOUR_VAR'].

Position the cursor inside the class, then press ALT + Ins and select Getters and Setters from the contextual menu.

JavaScript developers tend to refer to the above data-structure as either an object or hash instead of a Dictionary.

Your syntax above is wrong as you are initializing the users object as null. I presume this is a typo, as the code should read:

// Initialize users as a new hash.
var users = {};
users["182982"] = "...";

To retrieve all the values from a hash, you need to iterate over it using a for loop:

function getValues (hash) {
    var values = [];
    for (var key in hash) {

        // Ensure that the `key` is actually a member of the hash and not
        // a member of the `prototype`.
        // see: http://javascript.crockford.com/code.html#for%20statement
        if (hash.hasOwnProperty(key)) {
            values.push(key);
        }
    }
    return values;
};

If you plan on doing a lot of work with data-structures in JavaScript then the underscore.js library is definitely worth a look. Underscore comes with a values method which will perform the above task for you:

var values = _.values(users);

I don't use Angular myself, but I'm pretty sure there will be a convenience method build in for iterating over a hash's values (ah, there we go, Artem Andreev provides the answer above :))

See populate a database in the PostgreSQL manual, depesz's excellent-as-usual article on the topic, and this SO question.

(Note that this answer is about bulk-loading data into an existing DB or to create a new one. If you're interested DB restore performance with pg_restore or psql execution of pg_dump output, much of this doesn't apply since pg_dump and pg_restore already do things like creating triggers and indexes after it finishes a schema+data restore).

There's lots to be done. The ideal solution would be to import into an UNLOGGED table without indexes, then change it to logged and add the indexes. Unfortunately in PostgreSQL 9.4 there's no support for changing tables from UNLOGGED to logged. 9.5 adds ALTER TABLE ... SET LOGGED to permit you to do this.

If you can take your database offline for the bulk import, use pg_bulkload.

Otherwise:

• Disable any triggers on the table

• Drop indexes before starting the import, re-create them afterwards. (It takes much less time to build an index in one pass than it does to add the same data to it progressively, and the resulting index is much more compact).

• If doing the import within a single transaction, it's safe to drop foreign key constraints, do the import, and re-create the constraints before committing. Do not do this if the import is split across multiple transactions as you might introduce invalid data.

• If possible, use COPY instead of INSERTs

• If you can't use COPY consider using multi-valued INSERTs if practical. You seem to be doing this already. Don't try to list too many values in a single VALUES though; those values have to fit in memory a couple of times over, so keep it to a few hundred per statement.

• Batch your inserts into explicit transactions, doing hundreds of thousands or millions of inserts per transaction. There's no practical limit AFAIK, but batching will let you recover from an error by marking the start of each batch in your input data. Again, you seem to be doing this already.

• Use synchronous_commit=off and a huge commit_delay to reduce fsync() costs. This won't help much if you've batched your work into big transactions, though.

• INSERT or COPY in parallel from several connections. How many depends on your hardware's disk subsystem; as a rule of thumb, you want one connection per physical hard drive if using direct attached storage.

• Set a high checkpoint_segments value and enable log_checkpoints. Look at the PostgreSQL logs and make sure it's not complaining about checkpoints occurring too frequently.

• If and only if you don't mind losing your entire PostgreSQL cluster (your database and any others on the same cluster) to catastrophic corruption if the system crashes during the import, you can stop Pg, set fsync=off, start Pg, do your import, then (vitally) stop Pg and set fsync=on again. See WAL configuration. Do not do this if there is already any data you care about in any database on your PostgreSQL install. If you set fsync=off you can also set full_page_writes=off; again, just remember to turn it back on after your import to prevent database corruption and data loss. See non-durable settings in the Pg manual.

You should also look at tuning your system:

• Use good quality SSDs for storage as much as possible. Good SSDs with reliable, power-protected write-back caches make commit rates incredibly faster. They're less beneficial when you follow the advice above - which reduces disk flushes / number of fsync()s - but can still be a big help. Do not use cheap SSDs without proper power-failure protection unless you don't care about keeping your data.

• If you're using RAID 5 or RAID 6 for direct attached storage, stop now. Back your data up, restructure your RAID array to RAID 10, and try again. RAID 5/6 are hopeless for bulk write performance - though a good RAID controller with a big cache can help.

• If you have the option of using a hardware RAID controller with a big battery-backed write-back cache this can really improve write performance for workloads with lots of commits. It doesn't help as much if you're using async commit with a commit_delay or if you're doing fewer big transactions during bulk loading.

• If possible, store WAL (pg_xlog) on a separate disk / disk array. There's little point in using a separate filesystem on the same disk. People often choose to use a RAID1 pair for WAL. Again, this has more effect on systems with high commit rates, and it has little effect if you're using an unlogged table as the data load target.

When trying to silently install an MSI via PowerShell using this command:

Start-Process $webDeployInstallerFilePath -ArgumentList '/quiet' -Wait

I was getting the error:

The specified executable is not a valid application for this OS platform.

I instead switched to using msiexec.exe to execute the MSI with this command, and it worked as expected:

$arguments = "/i `"$webDeployInstallerFilePath`" /quiet"
Start-Process msiexec.exe -ArgumentList $arguments -Wait

Hopefully others find this useful.

fgets would work for you. here is very good documentation on this :-
http://www.cplusplus.com/reference/cstdio/fgets/

If you don't want to use fgets, following method will work for you :-

int readline(FILE *f, char *buffer, size_t len)
{
   char c; 
   int i;

   memset(buffer, 0, len);

   for (i = 0; i < len; i++)
   {   
      int c = fgetc(f); 

      if (!feof(f)) 
      {   
         if (c == '\r')
            buffer[i] = 0;
         else if (c == '\n')
         {   
            buffer[i] = 0;

            return i+1;
         }   
         else
            buffer[i] = c; 
      }   
      else
      {   
         //fprintf(stderr, "read_line(): recv returned %d\n", c);
         return -1; 
      }   
   }   

   return -1; 
}

The mouse's position is reported on the event object received by a handler for the mousemove event, which you can attach to the window (the event bubbles):

(function() {
    document.onmousemove = handleMouseMove;
    function handleMouseMove(event) {
        var eventDoc, doc, body;

        event = event || window.event; // IE-ism

        // If pageX/Y aren't available and clientX/Y are,
        // calculate pageX/Y - logic taken from jQuery.
        // (This is to support old IE)
        if (event.pageX == null && event.clientX != null) {
            eventDoc = (event.target && event.target.ownerDocument) || document;
            doc = eventDoc.documentElement;
            body = eventDoc.body;

            event.pageX = event.clientX +
              (doc && doc.scrollLeft || body && body.scrollLeft || 0) -
              (doc && doc.clientLeft || body && body.clientLeft || 0);
            event.pageY = event.clientY +
              (doc && doc.scrollTop  || body && body.scrollTop  || 0) -
              (doc && doc.clientTop  || body && body.clientTop  || 0 );
        }

        // Use event.pageX / event.pageY here
    }
})();

(Note that the body of that if will only run on old IE.)

Example of the above in action - it draws dots as you drag your mouse over the page. (Tested on IE8, IE11, Firefox 30, Chrome 38.)

If you really need a timer-based solution, you combine this with some state variables:

(function() {
    var mousePos;

    document.onmousemove = handleMouseMove;
    setInterval(getMousePosition, 100); // setInterval repeats every X ms

    function handleMouseMove(event) {
        var dot, eventDoc, doc, body, pageX, pageY;

        event = event || window.event; // IE-ism

        // If pageX/Y aren't available and clientX/Y are,
        // calculate pageX/Y - logic taken from jQuery.
        // (This is to support old IE)
        if (event.pageX == null && event.clientX != null) {
            eventDoc = (event.target && event.target.ownerDocument) || document;
            doc = eventDoc.documentElement;
            body = eventDoc.body;

            event.pageX = event.clientX +
              (doc && doc.scrollLeft || body && body.scrollLeft || 0) -
              (doc && doc.clientLeft || body && body.clientLeft || 0);
            event.pageY = event.clientY +
              (doc && doc.scrollTop  || body && body.scrollTop  || 0) -
              (doc && doc.clientTop  || body && body.clientTop  || 0 );
        }

        mousePos = {
            x: event.pageX,
            y: event.pageY
        };
    }
    function getMousePosition() {
        var pos = mousePos;
        if (!pos) {
            // We haven't seen any movement yet
        }
        else {
            // Use pos.x and pos.y
        }
    }
})();

As far as I'm aware, you can't get the mouse position without having seen an event, something which this answer to another Stack Overflow question seems to confirm.

Side note: If you're going to do something every 100ms (10 times/second), try to keep the actual processing you do in that function very, very limited. That's a lot of work for the browser, particularly older Microsoft ones. Yes, on modern computers it doesn't seem like much, but there is a lot going on in browsers... So for example, you might keep track of the last position you processed and bail from the handler immediately if the position hasn't changed.

It depends on what you want to do and what type of data/information you are displaying. In general, tables are reserved for displaying tabular data.

An alternate for your situation would be to use css. A simple option would be to float your image and give it a margin:

<p>
    <img style="float: left; margin: 5px;" ... />
    Text goes here...
</p>

This would cause the text to wrap around the image. If you don't want the text to wrap around the image, put the text in a separate container:

<div>
    <img style="float: left; margin: ...;" ... />
    <p style="float: right;">Text goes here...</p>
</div>

Note that it may be necessary to assign a width to the paragraph tag to display the way you'd like. Also note, for elements that appear below floated elements, you may need to add the style "clear: left;" (or clear: right, or clear: both).

The closest equivalent to Java's toString is to implement __str__ for your class. Put this in your class definition:

def __str__(self):
     return "foo"

You may also want to implement __repr__ to aid in debugging.

See here for more information:

• Special Method Names - Basic Customization

in a bash script the following works:

#!/bin/sh

text="this is line one\nthis is line two\nthis is line three"
echo -e $text > filename

alternatively:

text="this is line one
this is line two
this is line three"
echo "$text" > filename

cat filename gives:

this is line one
this is line two
this is line three

if you run fpm under ubuntu, need to run the code below (checked on 12 and 14)

If you face with the problem at the first time installing Android Studio on your computer.

1. mklink /D "c:\Android-Sdk" "C:\Users\ **YOUR-USERNAME** \AppData\Local\Android\sdk"

2. Go to "C:\Users\ YOUR-USERNAME \AppData\Local\" path and create Android\sdk folders inside it.

3. After that you can continue installation.

You should remove the & (ampersand) symbol, so that line 4 will look like this:

$conn = ADONewConnection($config['db_type']);

This is because ADONewConnection already returns an object by reference. As per documentation, assigning the result of a reference to object by reference results in an E_DEPRECATED message as of PHP 5.3.0

If you want to enable debug logging in tomcat for TLD scanned jars then you have to change /conf/logging.properties file in tomcat directory.

uncomment the line :
org.apache.jasper.servlet.TldScanner.level = FINE

FINE level is for debug log.

This should work for normal tomcat.

If the tomcat is running under eclipse. Then you have to set the path of tomcat logging.properties in eclipse.

1. Open servers view in eclipse.Stop the server.Double click your tomcat server.
   This will open Overview window for the server.
2. Click on Open launch configuration.This will open another window.
3. Go to the Arguments tab(second tab).Go to VM arguments section.
4. paste this two line there :-
   -Djava.util.logging.config.file="{CATALINA_HOME}\conf\logging.properties"
   -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
   Here CATALINA_HOME is your PC's corresponding tomcat server directory.
5. Save the Changes.Restart the server.

Now the jar files that scanned for TLDs should show in the log.

I -strongly- recommend build your HtmlHelpers. I think that apsx code will be more readable, reliable and durable.

On a MAC, you need to use nm *.o | c++filt, as there is no -C option in nm.

I'll take the risk of stating the obvious: You call the function, if it's defined in the base class it's automatically available in the derived class (unless it's private).

If there is a function with the same signature in the derived class you can disambiguate it by adding the base class's name followed by two colons base_class::foo(...). You should note that unlike Java and C#, C++ does not have a keyword for "the base class" (super or base) since C++ supports multiple inheritance which may lead to ambiguity.

class left {
public:
    void foo();
};

class right {
public:
    void foo();
};

class bottom : public left, public right {
public:
    void foo()
    {
        //base::foo();// ambiguous
        left::foo();
        right::foo();

        // and when foo() is not called for 'this':
        bottom b;
        b.left::foo();  // calls b.foo() from 'left'
        b.right::foo();  // call b.foo() from 'right'
    }
};

Incidentally, you can't derive directly from the same class twice since there will be no way to refer to one of the base classes over the other.

class bottom : public left, public left { // Illegal
};

Try this:

find /home/user/ -type f | xargs sed -i  's/a\.example\.com/b.example.com/g'

In case you want to ignore dot directories

find . \( ! -regex '.*/\..*' \) -type f | xargs sed -i 's/a\.example\.com/b.example.com/g'

Edit: escaped dots in search expression

If you know you will want a 'c' key, but do not know the value, insert 'c' with a dummy value when you create the dict.

d1 = OrderedDict([('c', None), ('a', '1'), ('b', '2')])

and change the value later.

d1['c'] = 3

Its also worth noting that by using Casting you do not actually need to create an object as in the answer given by @Bandula. Instead you can simply cast your array to an object and the stdClass is returned. For example:

$array = array(
    'Property1'=>'hello',
    'Property2'=>'world',
    'Property3'=>'again',
);

$obj = (object) $array;
echo $obj->Property3;

Output: again

You can use lambda to pass a reference to the window object as argument to close_window function:

button = Button (frame, text="Good-bye.", command = lambda: close_window(window))

This works because the command attribute is expecting a callable, or callable like object. A lambda is a callable, but in this case it is essentially the result of calling a given function with set parameters.

In essence, you're calling the lambda wrapper of the function which has no args, not the function itself.

On mac os, please follow below steps:

Stop MySQL

$ sudo /usr/local/mysql/support-files/mysql.server stop Start it in safe mode:

$ sudo mysqld_safe --skip-grant-tables (above line is the whole command)

This will be an ongoing command until the process is finished so open another shell/terminal window, log in without a password:

$ mysql -u root

mysql> UPDATE mysql.user SET Password=PASSWORD('password') WHERE User='root'; Start MySQL

sudo /usr/local/mysql/support-files/mysql.server start your new password is 'password'.

Sometimes when we do these steps:

 alter table my_table drop constraint my_pk; 
 alter table my_table add constraint my_pk primary key (city_id, buildtime, time);

The last statement fails with

ORA-00955 "name is already used by an existing object"

Oracle usually creates an unique index with the same name my_pk. In such a case you can drop the unique index or rename it based on whether the constraint is still relevant.

You can combine the dropping of primary key constraint and unique index into a single sql statement:

alter table my_table drop constraint my_pk drop index; 

check this: ORA-00955 "name is already used by an existing object"

If your text is in a Bash variable, then Parameter Substitution ${var//\\//} can replace substrings:

$ p='C:\foo\bar.xml'
$ printf '%s\n' "$p"
C:\foo\bar.xml
$ printf '%s\n' "${p//\\//}"
C:/foo/bar.xml

This may be leaner and clearer that filtering through a command such as tr or sed.

Check with your firewall expert. They open the firewall for PROD servers so there is no need to use the Proxy.

Thanks your tip helped me solve my problem:

Had to to set the Credentials in two locations to get past the 407 error:

HttpWebRequest webRequest = WebRequest.Create(uirTradeStream) as HttpWebRequest;
webRequest.Proxy = WebRequest.DefaultWebProxy;
webRequest.Credentials = new NetworkCredential("user", "password", "domain");
webRequest.Proxy.Credentials = new NetworkCredential("user", "password", "domain");

and voila!

Create a file called php.ini in the folder where your PHP file resides.

Inside php.ini add the following code (I am giving an simple error showing code):

display_startup_errors = on

It specifies the size of the log file to trigger rotation. For example size 50M will trigger a log rotation once the file is 50MB or greater in size. You can use the suffix M for megabytes, k for kilobytes, and G for gigabytes. If no suffix is used, it will take it to mean bytes. You can check the example at the end. There are three directives available size, maxsize, and minsize. According to manpage:

minsize size
              Log  files  are  rotated when they grow bigger than size bytes,
              but not before the additionally specified time interval (daily,
              weekly,  monthly, or yearly).  The related size option is simi-
              lar except that it is mutually exclusive with the time interval
              options,  and  it causes log files to be rotated without regard
              for the last rotation time.  When minsize  is  used,  both  the
              size and timestamp of a log file are considered.

size size
              Log files are rotated only if they grow bigger then size bytes.
              If size is followed by k, the size is assumed to  be  in  kilo-
              bytes.  If the M is used, the size is in megabytes, and if G is
              used, the size is in gigabytes. So size 100,  size  100k,  size
              100M and size 100G are all valid.
maxsize size
              Log files are rotated when they grow bigger than size bytes even before
              the additionally specified time interval (daily, weekly, monthly, 
              or yearly).  The related size option is  similar  except  that  it 
              is mutually exclusive with the time interval options, and it causes
              log files to be rotated without regard for the last rotation time.  
              When maxsize is used, both the size and timestamp of a log file are                  
              considered.

Here is an example:

"/var/log/httpd/access.log" /var/log/httpd/error.log {
           rotate 5
           mail [email protected]
           size 100k
           sharedscripts
           postrotate
               /usr/bin/killall -HUP httpd
           endscript
       }

Here is an explanation for both files /var/log/httpd/access.log and /var/log/httpd/error.log. They are rotated whenever it grows over 100k in size, and the old logs files are mailed (uncompressed) to [email protected] after going through 5 rotations, rather than being removed. The sharedscripts means that the postrotate script will only be run once (after the old logs have been compressed), not once for each log which is rotated. Note that the double quotes around the first filename at the beginning of this section allows logrotate to rotate logs with spaces in the name. Normal shell quoting rules apply, with ,, and \ characters supported.

I think the accepted way is better, but I guess this might work as well

function getElementByClass(&$parentNode, $tagName, $className, $offset = 0) {
    $response = false;

    $childNodeList = $parentNode->getElementsByTagName($tagName);
    $tagCount = 0;
    for ($i = 0; $i < $childNodeList->length; $i++) {
        $temp = $childNodeList->item($i);
        if (stripos($temp->getAttribute('class'), $className) !== false) {
            if ($tagCount == $offset) {
                $response = $temp;
                break;
            }

            $tagCount++;
        }

    }

    return $response;
}

You simply use the destroy() method to delete the specified widgets like this:

lbl = tk.Label(....)

btn = tk.Button(....., command=lambda: lbl.destroy())

Using this you can completely destroy the specific widgets.

Easy:

SELECT SUBSTR(OrderNo, 1, 2) FROM shipment;

This is to do with JavaScript's + in operator - if a number and a string are "added" up, the number is converted into a string:

0 + 1; //1
'0' + 1; // '01'

To solve this, use the + unary operator, or use parseInt():

+'0' + 1; // 1
parseInt('0', 10) + 1; // 1

The unary + operator converts it into a number (however if it's a decimal it will retain the decimal places), and parseInt() is self-explanatory (converts into number, ignoring decimal places).

The second argument is necessary for parseInt() to use the correct base when leading 0s are placed:

parseInt('010'); // 8 in older browsers, 10 in newer browsers
parseInt('010', 10); // always 10 no matter what

There's also parseFloat() if you need to convert decimals in strings to their numeric value - + can do that too but it behaves slightly differently: that's another story though.

You can use this code to onClick listener (you can use ImageView or button)

image.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
                startActivityForResult(takePictureIntent, 1);
            }
        }
    });

To display in your imageView

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
        Bundle extras = data.getExtras();
        bitmap = (Bitmap) extras.get("data");
        image.setImageBitmap(bitmap);

    }
}

Note: Insert this to the manifest

<uses-feature android:name="android.hardware.camera" android:required="true" />

Old question, but here's a fairly clean way to create a nullable parameter:

new SqlParameter("@note", (object) request.Body ?? DBNull.Value);

If request.Body has a value, then it's value is used. If it's null, then DbNull.Value is used.

Lately, partly to get better at LINQ.... I've been using Excel's automation API to save the file as XML Spreadsheet and then get process that file using LINQ to XML.

    var ua = window.navigator.userAgent;
    var ie = ua.search(/(MSIE|Trident|Edge)/);

You need to introduce your join condition before calling DefaultIfEmpty(). I would just use extension method syntax:

from p in context.Periods
join f in context.Facts on p.id equals f.periodid into fg
from fgi in fg.Where(f => f.otherid == 17).DefaultIfEmpty()
where p.companyid == 100
select f.value

Or you could use a subquery:

from p in context.Periods
join f in context.Facts on p.id equals f.periodid into fg
from fgi in (from f in fg
             where f.otherid == 17
             select f).DefaultIfEmpty()
where p.companyid == 100
select f.value

You could simply use * which unpacks the dictionary keys. Example:

d = {'x': 1, 'y': 2}
t = (*d,)
print(t) # ('x', 'y')

$output = file("http://www.example.com"); didn't work until I enabled: allow_url_fopen, allow_url_include, and file_uploads in php.ini for PHP7

If you want the year from a (unknown) datetime-object:

tijd = datetime.datetime(9999, 12, 31, 23, 59, 59)

>>> tijd.timetuple()
time.struct_time(tm_year=9999, tm_mon=12, tm_mday=31, tm_hour=23, tm_min=59, tm_sec=59, tm_wday=4, tm_yday=365, tm_isdst=-1)
>>> tijd.timetuple().tm_year
9999

.........

// ENCODE plainTextPassword String
byte[] cleartext = plainTextPassword.getBytes("UTF8");      

Cipher cipher = Cipher.getInstance("DES"); // cipher is not thread safe

String encryptedPwd = base64encoder.encode(cipher.doFinal(cleartext));
// now you can store it

// DECODE encryptedPwd String
byte[] encrypedPwdBytes = base64decoder.decodeBuffer(encryptedPwd);

Cipher cipher = Cipher.getInstance("DES");// cipher is not thread safe

byte[] plainTextPwdBytes = (cipher.doFinal(encrypedPwdBytes));

The method used for all previous answers to this question suggest changing the url which is not necessary, and I think readers should be aware of an alternative solution. I use ui-router and $stateProvider to associate a state value with a templateUrl which points to the html file for your view. Then it is just a matter of injecting the $state into your controller and calling $state.go('state-value') to update your view.

What is the difference between angular-route and angular-ui-router?

The necessary method is Mockito#verify:

public static <T> T verify(T mock,
                           VerificationMode mode)

mock is your mocked object and mode is the VerificationMode that describes how the mock should be verified. Possible modes are:

verify(mock, times(5)).someMethod("was called five times");
verify(mock, never()).someMethod("was never called");
verify(mock, atLeastOnce()).someMethod("was called at least once");
verify(mock, atLeast(2)).someMethod("was called at least twice");
verify(mock, atMost(3)).someMethod("was called at most 3 times");
verify(mock, atLeast(0)).someMethod("was called any number of times"); // useful with captors
verify(mock, only()).someMethod("no other method has been called on the mock");

You'll need these static imports from the Mockito class in order to use the verify method and these verification modes:

import static org.mockito.Mockito.atLeast;
import static org.mockito.Mockito.atLeastOnce;
import static org.mockito.Mockito.atMost;
import static org.mockito.Mockito.never;
import static org.mockito.Mockito.only;
import static org.mockito.Mockito.times;
import static org.mockito.Mockito.verify;

So in your case the correct syntax will be:

Mockito.verify(mock, times(4)).send()

This verifies that the method send was called 4 times on the mocked object. It will fail if it was called less or more than 4 times.

If you just want to check, if the method has been called once, then you don't need to pass a VerificationMode. A simple

verify(mock).someMethod("was called once");

would be enough. It internally uses verify(mock, times(1)).someMethod("was called once");.

It is possible to have multiple verification calls on the same mock to achieve a "between" verification. Mockito doesn't support something like this verify(mock, between(4,6)).someMethod("was called between 4 and 6 times");, but we can write

verify(mock, atLeast(4)).someMethod("was called at least four times ...");
verify(mock, atMost(6)).someMethod("... and not more than six times");

instead, to get the same behaviour. The bounds are included, so the test case is green when the method was called 4, 5 or 6 times.

WARNING: Necromancing

Still Darin Dimitrov's answer + System.Security.SecurityElement.Escape(string s) isn't complete.

In XML 1.1, the simplest and safest way is to just encode EVERYTHING.
Like 	 for \t.
It isn't supported at all in XML 1.0.
For XML 1.0, one possible workaround is to base-64 encode the text containing the character(s).

//string EncodedXml = SpecialXmlEscape("?????? ???");
//Console.WriteLine(EncodedXml);
//string DecodedXml = XmlUnescape(EncodedXml);
//Console.WriteLine(DecodedXml);
public static string SpecialXmlEscape(string input)
{
    //string content = System.Xml.XmlConvert.EncodeName("\t");
    //string content = System.Security.SecurityElement.Escape("\t");
    //string strDelimiter = System.Web.HttpUtility.HtmlEncode("\t"); // XmlEscape("\t"); //XmlDecode("	");
    //strDelimiter = XmlUnescape("&#59;");
    //Console.WriteLine(strDelimiter);
    //Console.WriteLine(string.Format("&#{0};", (int)';'));
    //Console.WriteLine(System.Text.Encoding.ASCII.HeaderName);
    //Console.WriteLine(System.Text.Encoding.UTF8.HeaderName);


    string strXmlText = "";

    if (string.IsNullOrEmpty(input))
        return input;


    System.Text.StringBuilder sb = new StringBuilder();

    for (int i = 0; i < input.Length; ++i)
    {
        sb.AppendFormat("&#{0};", (int)input[i]);
    }

    strXmlText = sb.ToString();
    sb.Clear();
    sb = null;

    return strXmlText;
} // End Function SpecialXmlEscape

XML 1.0:

public static string Base64Encode(string plainText)
{
    var plainTextBytes = System.Text.Encoding.UTF8.GetBytes(plainText);
    return System.Convert.ToBase64String(plainTextBytes);
}

public static string Base64Decode(string base64EncodedData)
{
    var base64EncodedBytes = System.Convert.FromBase64String(base64EncodedData);
    return System.Text.Encoding.UTF8.GetString(base64EncodedBytes);
}

I assume those XAML namespace declarations are in the parent tag of your control? You can't put comments inside of another tag. Other than that, the syntax you're using is correct.

<UserControl xmlns="...">
    <!-- Here's a valid comment. Notice it's outside the <UserControl> tag's braces -->
    [..snip..]
</UserControl>

You can use rows and cols:

cout << "Width : " << src.cols << endl;
cout << "Height: " << src.rows << endl;

or size():

cout << "Width : " << src.size().width << endl;
cout << "Height: " << src.size().height << endl;

<FilesMatch "\.(js|css)$">

</FilesMatch>

This is more of an xpath question, but like this, assuming the context is the parent element:

<xsl:value-of select="name/@attribute1" />

This worked for me:

ng-include src="'views/templates/drivingskills.html'"

complete div:

<div id="drivivgskills" ng-controller="DrivingSkillsCtrl" ng-view ng-include src="'views/templates/drivingskills.html'" ></div>

You should have gradle-wrapper.properties inside gradle/wrapper folder. Make sure you are using the right distributionURL, and the latest one. It should look something like this :

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-6.7-bin.zip
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists

You should build in some type matching relaxation to be more robust.

public static T ToEnum<T>(dynamic value)
{
    if (value == null)
    {
        // default value of an enum is the object that corresponds to
        // the default value of its underlying type
        // https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/default-values-table
        value = Activator.CreateInstance(Enum.GetUnderlyingType(typeof(T)));
    }
    else if (value is string name)
    {
        return (T)Enum.Parse(typeof(T), name);
    }

    return (T)Enum.ToObject(typeof(T),
             Convert.ChangeType(value, Enum.GetUnderlyingType(typeof(T))));
}

Test Case

[Flags]
public enum A : uint
{
    None  = 0, 
    X     = 1 < 0,
    Y     = 1 < 1
}

static void Main(string[] args)
{
    var value = EnumHelper.ToEnum<A>(7m);
    var x = value.HasFlag(A.X); // true
    var y = value.HasFlag(A.Y); // true

    var value2 = EnumHelper.ToEnum<A>("X");

    var value3 = EnumHelper.ToEnum<A>(null);

    Console.ReadKey();
}

to get the last value from a column you can also use MAX function with IF function

=ARRAYFORMULA(INDIRECT("G"&MAX(IF(G:G<>"", ROW(G:G), )), 4)))

I changed this line in devise.rb:

config.sign_out_via = :delete

to

config.sign_out_via = :get

and it started working for me.

The reason that does not work is because this has no specific meaning inside of an if statement, you will have to go back to a level of scope where this is defined (a function).

For example:

$('#element1').click(function() {
    console.log($(this).attr('id')); // logs "element1"

    if ($('#element2').hasClass('class')) {
        console.log($(this).attr('id')); // still logs "element1"
    }
});

If you want the actual HTTP Host header, see Daniel Roseman's comment on @Phsiao's answer. The other alternative is if you're using the contrib.sites framework, you can set a canonical domain name for a Site in the database (mapping the request domain to a settings file with the proper SITE_ID is something you have to do yourself via your webserver setup). In that case you're looking for:

from django.contrib.sites.models import Site

current_site = Site.objects.get_current()
current_site.domain

you'd have to put the current_site object into a template context yourself if you want to use it. If you're using it all over the place, you could package that up in a template context processor.

Component 2, the directive component can define a input property (@input annotation in Typescript). And Component 1 can pass that property to the directive component from template.

See this SO answer How to do inter communication between a master and detail component in Angular2?

and how input is being passed to child components. In your case it is directive.

It sounds like the application isn't signed. Download ldid from Cydia and then use it like so: ldid -S /Applications/AccelerometerGraph.app/AccelerometerGraph

Also be sure that the binary is marked as executable: chmod +x /Applications/AccelerometerGraph.app/AccelerometerGraph

Don't abuse form elements where <a> elements will suffice.

<style>
    /* or put this in your stylesheet */

    .button {
        display: inline-block;
        padding: 3px 5px;
        border: 1px solid #000;
        background: #eee;
    }

</style>

<!-- instead of abusing a button or input element -->
<a href="url" class="button">text</a>

Tim Lentine's answer seems to be true even in the full release. There is just one other thing I would like to mention.

If you complete your import without going into "Advanced..." and saving the spec, but you do save the import for reuse at the end of the wizard (new feature AFAIK), you will not be able to go back and edit that spec. It is built into the "Saved Import". This may be what Knox was referring to.

You can, however, do a partial work around:

1. Import a new file (or the same one all over again) but,
2. This time choose to append, instead of making a new
3. Click OK.
4. Go into "advanced" All your column heading and data-types will be there.
5. Now you can make the changes you need and save the spec inside that dialog. Then cancel out of that import (that is not what you wanted anyway, right?)
6. You can then use that spec for any further imports. It's not a full solution, but saves some of the work.

Insert an XML comment. ;-)

/// <summary>
/// Describe your member here.
/// </summary>
public string Something
{
    get;
    set;
}

This may appear like a joke at the first glance, but it may actually be useful. For me it turned out to be helpful to think about what methods do even for private methods (unless really trivial, of course).

SELECT distinct CITY 
FROM STATION 
where (CITY LIKE 'a%' 
    OR CITY LIKE 'e%' 
    OR CITY LIKE 'i%' 
    OR CITY LIKE 'o%'
    OR CITY LIKE 'u%'
) AND (CITY LIKE '%a' 
    OR CITY LIKE '%e'
    OR CITY LIKE '%i'
    OR CITY LIKE '%o'
    OR CITY LIKE '%u'
)

We can also use it for the guideline of the constraint layout.

Create integer.xml file and add into

 <item name="guideline_button_top" type="integer" format="float">0.60</item>

Use from a layout.xml file

 app:layout_constraintGuide_percent="@integer/guideline_button_top" 

Both the mongod (database server) and mongo (database client shell) programs are command line programs and each expects to be run in its own command line session. So, after starting the server (as you did with "./mongod") you should open a second command line session and run "./mongo" in it to give you a command line shell for talking to the server.

find "${search_dir}" "${work_dir}" -mindepth 1 -maxdepth 1 -type f -print0 | xargs -0 -I {} echo "{}"

I got exceptions in the linq-code so I do it this way (without a complicated extension):

private static IList<Type> loadAllImplementingTypes(Type[] interfaces)
{
    IList<Type> implementingTypes = new List<Type>();

    // find all types
    foreach (var interfaceType in interfaces)
        foreach (var currentAsm in AppDomain.CurrentDomain.GetAssemblies())
            try
            {
                foreach (var currentType in currentAsm.GetTypes())
                    if (interfaceType.IsAssignableFrom(currentType) && currentType.IsClass && !currentType.IsAbstract)
                        implementingTypes.Add(currentType);
            }
            catch { }

    return implementingTypes;
}

plt.subplots() is a function that returns a tuple containing a figure and axes object(s). Thus when using fig, ax = plt.subplots() you unpack this tuple into the variables fig and ax. Having fig is useful if you want to change figure-level attributes or save the figure as an image file later (e.g. with fig.savefig('yourfilename.png')). You certainly don't have to use the returned figure object but many people do use it later so it's common to see. Also, all axes objects (the objects that have plotting methods), have a parent figure object anyway, thus:

fig, ax = plt.subplots()

is more concise than this:

fig = plt.figure()
ax = fig.add_subplot(111)

Monolithic kernel

All the parts of a kernel like the Scheduler, File System, Memory Management, Networking Stacks, Device Drivers, etc., are maintained in one unit within the kernel in Monolithic Kernel

Advantages

•Faster processing

Disadvantages

•Crash Insecure •Porting Inflexibility •Kernel Size explosion

Examples •MS-DOS, Unix, Linux

Micro kernel

Only the very important parts like IPC(Inter process Communication), basic scheduler, basic memory handling, basic I/O primitives etc., are put into the kernel. Communication happen via message passing. Others are maintained as server processes in User Space

Advantages

•Crash Resistant, Portable, Smaller Size

Disadvantages

•Slower Processing due to additional Message Passing

Examples •Windows NT

If you have a compiler that supports C99 you can

#include <stdbool.h>

Otherwise, you can define your own if you'd like. Depending on how you want to use it (and whether you want to be able to compile your code as C++), your implementation could be as simple as:

#define bool int
#define true 1
#define false 0

In my opinion, though, you may as well just use int and use zero to mean false and nonzero to mean true. That's how it's usually done in C.

How about something like this:

SELECT c.constraint_name, c.constraint_type, c2.constraint_name, c2.constraint_type, c2.table_name
  FROM dba_constraints c JOIN dba_constraints c2 ON (c.r_constraint_name = c2.constraint_name)
 WHERE c.table_name = <TABLE_OF_INTEREST>
   AND c.constraint_TYPE = 'R';

to delete your app database try this:

 this.deleteDatabase("databasename.db");

this will delete the database file

Bootstrap 3 now has Responsive tables out of the box. Hooray! :)

You can check it here: https://getbootstrap.com/docs/3.3/css/#tables-responsive

Add a <div class="table-responsive"> surrounding your table and you should be good to go:

<div class="table-responsive">
  <table class="table">
    ...
  </table>
</div>

To make it work on all layouts you can do this:

.table-responsive
{
    overflow-x: auto;
}

Yes include the first file into the second. That's all.

See an example below,

File1.php :

<?php
  function first($int, $string){ //function parameters, two variables.
    return $string;  //returns the second argument passed into the function
  }
?>

Now Using include (http://php.net/include) to include the File1.php to make its content available for use in the second file:

File2.php :

<?php
  include 'File1.php';
  echo first(1,"omg lol"); //returns omg lol;
?>

Another potential cause:

I had this issue when I was accidentally presenting the same view controller twice. (Once with performSegueWithIdentifer:sender: which was called when the button was pressed, and a second time with a segue connected directly to the button).

Effectively, two segues were firing at the same time, and I got the error: Attempt to present X on Y whose view is not in the window hierarchy!

You can use this command and the video duration is still unaltered.

ffmpeg -i input.mp4 -r 24 output.mp4

I get this code works on my browser:

<!--[if lt IE 9]>
  <script src="https://oss.maxcdn.com/libs/html5shiv/3.7.0/html5shiv.js"></script>

<![endif]-->

Note for this code: HTML5 Shiv and Respond.js IE8 support of HTML5 elements and media queries

Another option is to add style to div

<div style="position: absolute; height:somePercentage%; overflow:auto(or other overflow value)">
 //to be scrolled 
</div>

And it means that an element is positioned relative to the nearest positioned ancestor.

Underscore.js is great for this kind of thing. You can use _.countBy() to get the counts per name:

data = [{"id":11,"name":"ajax","subject":"OR","mark":63},
        {"id":12,"name":"javascript","subject":"OR","mark":63},
        {"id":13,"name":"jquery","subject":"OR","mark":63},
        {"id":14,"name":"ajax","subject":"OR","mark":63},
        {"id":15,"name":"jquery","subject":"OR","mark":63},
        {"id":16,"name":"ajax","subject":"OR","mark":63},
        {"id":20,"name":"ajax","subject":"OR","mark":63}]

_.countBy(data, function(data) { return data.name; });

Gives:

{ajax: 4, javascript: 1, jquery: 2} 

For an array of the keys just use _.keys()

_.keys(_.countBy(data, function(data) { return data.name; }));

Gives:

["ajax", "javascript", "jquery"]

When the iFrame points to your site like this:

<html>
  <head>
    <script type="text/javascript" src="/jquery.js"></script>
  </head>
  <body>
    <iframe id="my_frame" src="/wherev"></iframe>
  </body>
</html>

You can access iFrame DOM through this kind of thing.

var iframeBody = $(window.my_frame.document.getElementsByTagName("body")[0]);
iframeBody.append($("<h1/>").html("Hello world!"));

You can execute a Bash script in debug mode with the -x option.

This will echo all the commands.

bash -x example_script.sh

# Console output
+ cd /home/user
+ mv text.txt mytext.txt

You can also save the -x option in the script. Just specify the -x option in the shebang.

######## example_script.sh ###################
#!/bin/bash -x

cd /home/user
mv text.txt mytext.txt

##############################################

./example_script.sh

# Console output
+ cd /home/user
+ mv text.txt mytext.txt

Another solution:

for /f "tokens=2 delims==" %%I in ('wmic os get localdatetime /format:list') do set datetime=%%I

It will give you (independent of locale settings!):

  20130802203023.304000+120
( YYYYMMDDhhmmss.<milliseconds><always 000>+/-<minutes difference to UTC>  )

From here, it is easy:

set datetime=%datetime:~0,8%-%datetime:~8,6%
20130802-203023

For Logan's request for the same outputformat for the "date-time modified" of a file:

for %%F in (test.txt) do set file=%%~fF
for /f "tokens=2 delims==" %%I in ('wmic datafile where name^="%file:\=\\%" get lastmodified /format:list') do set datetime=%%I
echo %datetime%

It is a bit more complicated, because it works only with full paths, wmic expects the backslashes to be doubled and the = has to be escaped (the first one. The second one is protected by surrounding quotes).

How about this?

JSONObject jsonObject = new JSONObject           (YOUR_JSON_STRING);
JSONObject ipinfo     = jsonObject.getJSONObject ("ipinfo");
String     ip_address = ipinfo.getString         ("ip_address");
JSONObject location   = ipinfo.getJSONObject     ("Location");
String     latitude   = location.getString       ("latitude");
System.out.println (latitude);

This sample code using "org.json.JSONObject"

After </body> tag:

<script type="text/javascript">
if (location.href.indexOf('reload')==-1)
{
   location.href=location.href+'?reload';
}
</script>

Until PHP 5.3 release don't expect to have a good ORM. It's a OO limitation of PHP.

Limit the number of words with a custom Angular filter: Here is how I used an Angular filter to limit the number of words displayed using a custom filter.

HTML:

<span>{{dataModelObject.TextValue | limitWordsTo: 38}} ......</span>

Angular/Javascript Code

angular.module('app')
.filter('limitWordsTo', function () {
    return function (stringData, numberOfWords) {
        //Get array of words (determined by spaces between words)
        var arrayOfWords = stringData.split(" ");

        //Get loop limit
        var loopLimit = numberOfWords > arrayOfWords.length ? arrayOfWords.length : numberOfWords;

        //Create variables to hold limited word string and array iterator
        var limitedString = '', i;
        //Create limited string bounded by limit passed in
        for (i = 0; i < loopLimit; i++) {
            if (i === 0) {
                limitedString = arrayOfWords[i];
            } else {
                limitedString = limitedString + ' ' + arrayOfWords[i];
            }
        }
        return limitedString;
    }; 
}); //End filter

x=[1,2,3,4,5]
sum=0
for s in range(0,len(x)):
   sum=sum+x[s]
print sum   

You can get around this by using the simulator if you don't actually need to be deploying to a device. That solved it for me.

I just tested this and it works in Access 2010.

Say you have a SELECT query with parameters:

PARAMETERS startID Long, endID Long;
SELECT Members.*
FROM Members
WHERE (((Members.memberID) Between [startID] And [endID]));

You run that query interactively and it prompts you for [startID] and [endID]. That works, so you save that query as [MemberSubset].

Now you create an UPDATE query based on that query:

UPDATE Members SET Members.age = [age]+1
WHERE (((Members.memberID) In (SELECT memberID FROM [MemberSubset])));

You run that query interactively and again you are prompted for [startID] and [endID] and it works well, so you save it as [MemberSubsetUpdate].

You can run [MemberSubsetUpdate] from VBA code by specifying [startID] and [endID] values as parameters to [MemberSubsetUpdate], even though they are actually parameters of [MemberSubset]. Those parameter values "trickle down" to where they are needed, and the query does work without human intervention:

Sub paramTest()
    Dim qdf As DAO.QueryDef
    Set qdf = CurrentDb.QueryDefs("MemberSubsetUpdate")
    qdf!startID = 1  ' specify
    qdf!endID = 2    '     parameters
    qdf.Execute
    Set qdf = Nothing
End Sub

use

range(count)

int and float are not iterable

For those who don't want elegant solutions, just a quick and dirty way to stop those messages, here is a solution that worked for me (I use Hibernate 4.3.6 and Eclipse and no answers provided above (or found on the internet) worked; neither log4j config files nor setting the logging level programatically)

public static void main(String[] args) {
    //magical - do not touch
    @SuppressWarnings("unused")
    org.jboss.logging.Logger logger = org.jboss.logging.Logger.getLogger("org.hibernate");
    java.util.logging.Logger.getLogger("org.hibernate").setLevel(java.util.logging.Level.WARNING); //or whatever level you need

    ...
}

I used it in a tutorial program downloaded from this site

The official answer from Facebook (http://developers.facebook.com/bugs/282710765082535):

Mikhail,

The facebook android sdk no longer supports android 1.5 and 1.6. Please upgrade to the next api version.

Good luck with your implementation.

Usage depends on whether the component's parent has a layout manager or not.

• setSize() -- use when a parent layout manager does not exist;
• setPreferredSize() (also its related setMinimumSize and setMaximumSize) -- use when a parent layout manager exists.

The setSize() method probably won't do anything if the component's parent is using a layout manager; the places this will typically have an effect would be on top-level components (JFrames and JWindows) and things that are inside of scrolled panes. You also must call setSize() if you've got components inside a parent without a layout manager.

Generally, setPreferredSize() will lay out the components as expected if a layout manager is present; most layout managers work by getting the preferred (as well as minimum and maximum) sizes of their components, then using setSize() and setLocation() to position those components according to the layout's rules.

For example, a BorderLayout tries to make the bounds of its "north" region equal to the preferred size of its north component---they may end up larger or smaller than that, depending on the size of the JFrame, the size of the other components in the layout, and so on.

You can try this, and if it will find any space it will return the position where the first space is.

--cursor variable declaration 
variable Out_Ref_Cursor refcursor;
--execute procedure 
execute get_employees_name(IN_Variable,:Out_Ref_Cursor);
--display result referenced by ref cursor.
print Out_Ref_Cursor;

after passing the vector by reference

swap(vector[position],vector[otherPosition]);

will produce the expected result.

try this :Float.valueOf(android.os.Build.VERSION.RELEASE) <= 2.1

gene_name = no_headers.iloc[1:,[1]]

This creates a DataFrame because you passed a list of columns (single, but still a list). When you later do this:

gene_name[x]

you now have a Series object with a single value. You can't hash the Series.

The solution is to create Series from the start.

gene_type = no_headers.iloc[1:,0]
gene_name = no_headers.iloc[1:,1]
disease_name = no_headers.iloc[1:,2]

Also, where you have orph_dict[gene_name[x]] =+ 1, I'm guessing that's a typo and you really mean orph_dict[gene_name[x]] += 1 to increment the counter.

Please correct me if I'm wrong.`

'data' should be a stringified JavaScript object:

data: JSON.stringify({ "userName": userName, "password" : password })

To send your formData, pass it to stringify:

data: JSON.stringify(formData)

Some servers also require the application/json content type:

contentType: 'application/json'

There's also a more detailed answer to a similar question here: Jquery Ajax Posting json to webservice

Use a BinaryReader object to return a byte array from the stream like:

byte[] fileData = null;
using (var binaryReader = new BinaryReader(Request.Files[0].InputStream))
{
    fileData = binaryReader.ReadBytes(Request.Files[0].ContentLength);
}

If you save the state of the application in a bundle (typically non-persistent, dynamic data in onSaveInstanceState), it can be passed back to onCreate if the activity needs to be recreated (e.g., orientation change) so that you don't lose this prior information. If no data was supplied, savedInstanceState is null.

... you should use the onPause() method to write any persistent data (such as user edits) to storage. In addition, the method onSaveInstanceState(Bundle) is called before placing the activity in such a background state, allowing you to save away any dynamic instance state in your activity into the given Bundle, to be later received in onCreate(Bundle) if the activity needs to be re-created. See the Process Lifecycle section for more information on how the lifecycle of a process is tied to the activities it is hosting. Note that it is important to save persistent data in onPause() instead of onSaveInstanceState(Bundle) because the latter is not part of the lifecycle callbacks, so will not be called in every situation as described in its documentation.

Make sure your list parameter does not contain null values.

Here's an explanation:

WHERE field1 NOT IN (1, 2, 3, null)

is the same as:

WHERE NOT (field1 = 1 OR field1 = 2 OR field1 = 3 OR field1 = null)

• That last comparision evaluates to null.
• That null is OR'd with the rest of the boolean expression, yielding null. (*)
• null is negated, yielding null.
• null is not true - the where clause only keeps true rows, so all rows are filtered.

(*) Edit: this explanation is pretty good, but I wish to address one thing to stave off future nit-picking. (TRUE OR NULL) would evaluate to TRUE. This is relevant if field1 = 3, for example. That TRUE value would be negated to FALSE and the row would be filtered.

I had the same issue. Tried all the above answers. It was actually complained about a .dll file. I clean the project in Visual Studio but the .dll file still remains, so I deleted in manually from the bin folder and it worked.

Or try to check your mainActivity.xml you make sure that this one
xmlns:app="http://schemas.android.com/apk/res-auto"hereis included

The functions in the other answers are overkill for escaping entire regular expressions (they may be useful for escaping parts of regular expressions that will later be concatenated into bigger regexps).

If you escape an entire regexp and are done with it, quoting the metacharacters that are either standalone (., ?, +, *, ^, $, |, \) or start something ((, [, {) is all you need:

String.prototype.regexEscape = function regexEscape() {
  return this.replace(/[.?+*^$|({[\\]/g, '\\$&');
};

And yes, it's disappointing that JavaScript doesn't have a function like this built-in.

One of Androids powerful feature is the AsyncTask class.

To work with it, you have to first extend it and override doInBackground(...). doInBackground automatically executes on a worker thread, and you can add some listeners on the UI Thread to get notified about status update, those functions are called: onPreExecute(), onPostExecute() and onProgressUpdate()

You can find a example here.

Refer to below post for other alternatives:

Handler vs AsyncTask vs Thread

[Joke mode on]

You can fix this by adding this:

https://github.com/donavon/undefined-is-a-function

import { undefined } from 'undefined-is-a-function';
// Fixed! undefined is now a function.

[joke mode off]

Your formula is wrong. You probably meant something like:

=IF(AND(NOT(ISBLANK(Q2));NOT(ISBLANK(R2)));IF(Q2<=R2;"1";"0");"")

Another equivalent:

=IF(NOT(OR(ISBLANK(Q2);ISBLANK(R2)));IF(Q2<=R2;"1";"0");"")

Or even shorter:

=IF(OR(ISBLANK(Q2);ISBLANK(R2));"";IF(Q2<=R2;"1";"0"))

OR EVEN SHORTER:

=IF(OR(ISBLANK(Q2);ISBLANK(R2));"";--(Q2<=R2))

I search a way to map a many-to-many association table with extra column(s) with hibernate in xml files configuration.

Assuming with have two table 'a' & 'c' with a many to many association with a column named 'extra'. Cause I didn't find any complete example, here is my code. Hope it will help :).

First here is the Java objects.

public class A implements Serializable{  

    protected int id;
    // put some others fields if needed ...   
    private Set<AC> ac = new HashSet<AC>();

    public A(int id) {
        this.id = id;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public Set<AC> getAC() {
        return ac;
    }

    public void setAC(Set<AC> ac) {
        this.ac = ac;
    }

    /** {@inheritDoc} */
    @Override
    public int hashCode() {
        final int prime = 97;
        int result = 1;
        result = prime * result + id;
        return result;
    }

    /** {@inheritDoc} */
    @Override
    public boolean equals(Object obj) {
        if (this == obj)
            return true;
        if (obj == null)
            return false;
        if (!(obj instanceof A))
            return false;
        final A other = (A) obj;
        if (id != other.getId())
            return false;
        return true;
    }

}

public class C implements Serializable{

    protected int id;
    // put some others fields if needed ...    

    public C(int id) {
        this.id = id;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    /** {@inheritDoc} */
    @Override
    public int hashCode() {
        final int prime = 98;
        int result = 1;
        result = prime * result + id;
        return result;
    }

    /** {@inheritDoc} */
    @Override
    public boolean equals(Object obj) {
        if (this == obj)
            return true;
        if (obj == null)
            return false;
        if (!(obj instanceof C))
            return false;
        final C other = (C) obj;
        if (id != other.getId())
            return false;
        return true;
    }

}

Now, we have to create the association table. The first step is to create an object representing a complex primary key (a.id, c.id).

public class ACId implements Serializable{

    private A a;
    private C c;

    public ACId() {
        super();
    }

    public A getA() {
        return a;
    }
    public void setA(A a) {
        this.a = a;
    }
    public C getC() {
        return c;
    }
    public void setC(C c) {
        this.c = c;
    }
    @Override
    public int hashCode() {
        final int prime = 31;
        int result = 1;
        result = prime * result + ((a == null) ? 0 : a.hashCode());
        result = prime * result
                + ((c == null) ? 0 : c.hashCode());
        return result;
    }
    @Override
    public boolean equals(Object obj) {
        if (this == obj)
            return true;
        if (obj == null)
            return false;
        if (getClass() != obj.getClass())
            return false;
        ACId other = (ACId) obj;
        if (a == null) {
            if (other.a != null)
                return false;
        } else if (!a.equals(other.a))
            return false;
        if (c == null) {
            if (other.c != null)
                return false;
        } else if (!c.equals(other.c))
            return false;
        return true;
    }
}

Now let's create the association object itself.

public class AC implements java.io.Serializable{

    private ACId id = new ACId();
    private String extra;

    public AC(){

    }

    public ACId getId() {
        return id;
    }

    public void setId(ACId id) {
        this.id = id;
    }

    public A getA(){
        return getId().getA();
    }

    public C getC(){
        return getId().getC();
    }

    public void setC(C C){
        getId().setC(C);
    }

    public void setA(A A){
        getId().setA(A);
    }

    public String getExtra() {
        return extra;
    }

    public void setExtra(String extra) {
        this.extra = extra;
    }

    public boolean equals(Object o) {
        if (this == o)
            return true;
        if (o == null || getClass() != o.getClass())
            return false;

        AC that = (AC) o;

        if (getId() != null ? !getId().equals(that.getId())
                : that.getId() != null)
            return false;

        return true;
    }

    public int hashCode() {
        return (getId() != null ? getId().hashCode() : 0);
    }
}

At this point, it's time to map all our classes with hibernate xml configuration.

A.hbm.xml and C.hxml.xml (quiete the same).

<class name="A" table="a">
        <id name="id" column="id_a" unsaved-value="0">
            <generator class="identity">
                <param name="sequence">a_id_seq</param>
            </generator>
        </id>
<!-- here you should map all others table columns -->
<!-- <property name="otherprop" column="otherprop" type="string" access="field" /> -->
    <set name="ac" table="a_c" lazy="true" access="field" fetch="select" cascade="all">
        <key>
            <column name="id_a" not-null="true" />
        </key>
        <one-to-many class="AC" />
    </set>
</class>

<class name="C" table="c">
        <id name="id" column="id_c" unsaved-value="0">
            <generator class="identity">
                <param name="sequence">c_id_seq</param>
            </generator>
        </id>
</class>

And then association mapping file, a_c.hbm.xml.

<class name="AC" table="a_c">
    <composite-id name="id" class="ACId">
        <key-many-to-one name="a" class="A" column="id_a" />
        <key-many-to-one name="c" class="C" column="id_c" />
    </composite-id>
    <property name="extra" type="string" column="extra" />
</class>

Here is the code sample to test.

A = ADao.get(1);
C = CDao.get(1);

if(A != null && C != null){
    boolean exists = false;
            // just check if it's updated or not
    for(AC a : a.getAC()){
        if(a.getC().equals(c)){
            // update field
            a.setExtra("extra updated");
            exists = true;
            break;
        }
    }

    // add 
    if(!exists){
        ACId idAC = new ACId();
        idAC.setA(a);
        idAC.setC(c);

        AC AC = new AC();
        AC.setId(idAC);
        AC.setExtra("extra added"); 
        a.getAC().add(AC);
    }

    ADao.save(A);
}

Sort the file randomly and pick first 100 lines:

$ sort -R input | head -n 100 >output

The bug you reference (bug 4787391) has been fixed in Java 8. Even if you are using an older version of Java, the System.getProperty("user.home") approach is probably still the best. The user.home approach seems to work in a very large number of cases. A 100% bulletproof solution on Windows is hard, because Windows has a shifting concept of what the home directory means.

If user.home isn't good enough for you I would suggest choosing a definition of home directory for windows and using it, getting the appropriate environment variable with System.getenv(String).

Your text may be located in the networking response.There is also a search tool in the Network tab, and you may try it.

What you want to search for may stay either in DOM or in memory. If it is not in DOM, well, it may be in memory, because you have just see it in your computer screen anyway. The text you search for may be loaded either from scripts in the initial DOM or from response in the later request.

I added the control to the Triggers tag in the update panel:

    </ContentTemplate>
    <Triggers>
        <asp:PostBackTrigger ControlID="exportLinkButton" />
    </Triggers>
</asp:UpdatePanel>

This way the exportLinkButton will trigger the UpdatePanel to update.

Here is the code of ReadDoc/docx.java: This will read a dox/docx file and print its content to the console. you can customize it your way.

import java.io.*;

import org.apache.poi.hwpf.extractor.WordExtractor;

public class ReadDocFile
{
    public static void main(String[] args)
    {
        File file = null;
        WordExtractor extractor = null;
        try
        {

            file = new File("c:\\New.doc");
            FileInputStream fis = new FileInputStream(file.getAbsolutePath());
            HWPFDocument document = new HWPFDocument(fis);
            extractor = new WordExtractor(document);
            String[] fileData = extractor.getParagraphText();
            for (int i = 0; i < fileData.length; i++)
            {
                if (fileData[i] != null)
                    System.out.println(fileData[i]);
            }
        }
        catch (Exception exep)
        {
            exep.printStackTrace();
        }
    }
}

I recently solved this problem by using table-caption, though I cannot say if it is recommended. The other answers didn't seem to workout in my case.

h1 {
  display: table-caption;
}

A robust solution is to delegate counting to a subroutine invoked with call; the subroutine uses goto statements to emulate a loop in which shift is used to consume the (subroutine-only) arguments iteratively:

@echo off
setlocal

:: Call the argument-counting subroutine with all arguments received,
:: without interfering with the ability to reference the arguments
:: with %1, ... later.
call :count_args %*

:: Print the result.
echo %ReturnValue% argument(s) received.

:: Exit the batch file.
exit /b

:: Subroutine that counts the arguments given.
:: Returns the count in %ReturnValue%
:count_args
  set /a ReturnValue = 0
  :count_args_for

    if %1.==. goto :eof

    set /a ReturnValue += 1

    shift
  goto count_args_for
