What we ended up doing is stopped using the class components and created Functional Components, using useEffect() from the Hooks API for lifecycle methods. This allows you to still use makeStyles() with Lifecycle Methods without adding the complication of making Higher-Order Components. Which is much simpler.

Example:

import React, { useEffect, useState } from 'react';
import axios from 'axios';
import { Redirect } from 'react-router-dom';

import { Container, makeStyles } from '@material-ui/core';

import LogoButtonCard from '../molecules/Cards/LogoButtonCard';

const useStyles = makeStyles(theme => ({
  root: {
    display: 'flex',
    alignItems: 'center',
    justifyContent: 'center',
    margin: theme.spacing(1)
  },
  highlight: {
    backgroundColor: 'red',
  }
}));

// Highlight is a bool
const Welcome = ({highlight}) => { 
  const [userName, setUserName] = useState('');
  const [isAuthenticated, setIsAuthenticated] = useState(true);
  const classes = useStyles();

  useEffect(() => {
    axios.get('example.com/api/username/12')
         .then(res => setUserName(res.userName));
  }, []);

  if (!isAuthenticated()) {
    return <Redirect to="/" />;
  }
  return (
    <Container maxWidth={false} className={highlight ? classes.highlight : classes.root}>
      <LogoButtonCard
        buttonText="Enter"
        headerText={isAuthenticated && `Welcome, ${userName}`}
        buttonAction={login}
      />
   </Container>
   );
  }
}

export default Welcome;

The reason for this error occurs is that you are using the CryptoListPresenter _presenter without initializing.

I found that CryptoListPresenter _presenter would have to be initialized to fix because _presenter.loadCurrencies() is passing through a null variable at the time of instantiation;

there are two ways to initialize

1. Can be initialized during an declaration, like this

   CryptoListPresenter _presenter = CryptoListPresenter();
   

2. In the second, initializing(with assigning some value) it when initState is called, which the framework will call this method once for each state object.

   @override
   void initState() {
     _presenter = CryptoListPresenter(...);
   }
   

On a rather unrelated note: more performance hacks!

• [the first «conjecture» has been finally debunked by @ShreevatsaR; removed]

• When traversing the sequence, we can only get 3 possible cases in the 2-neighborhood of the current element N (shown first):

  1. [even] [odd]
  2. [odd] [even]
  3. [even] [even]

  To leap past these 2 elements means to compute (N >> 1) + N + 1, ((N << 1) + N + 1) >> 1 and N >> 2, respectively.

  Let`s prove that for both cases (1) and (2) it is possible to use the first formula, (N >> 1) + N + 1.

  Case (1) is obvious. Case (2) implies (N & 1) == 1, so if we assume (without loss of generality) that N is 2-bit long and its bits are ba from most- to least-significant, then a = 1, and the following holds:

  (N << 1) + N + 1:     (N >> 1) + N + 1:
  
          b10                    b1
           b1                     b
         +  1                   + 1
         ----                   ---
         bBb0                   bBb
  

  where B = !b. Right-shifting the first result gives us exactly what we want.

  Q.E.D.: (N & 1) == 1 ? (N >> 1) + N + 1 == ((N << 1) + N + 1) >> 1.

  As proven, we can traverse the sequence 2 elements at a time, using a single ternary operation. Another 2× time reduction.

The resulting algorithm looks like this:

uint64_t sequence(uint64_t size, uint64_t *path) {
    uint64_t n, i, c, maxi = 0, maxc = 0;

    for (n = i = (size - 1) | 1; i > 2; n = i -= 2) {
        c = 2;
        while ((n = ((n & 3)? (n >> 1) + n + 1 : (n >> 2))) > 2)
            c += 2;
        if (n == 2)
            c++;
        if (c > maxc) {
            maxi = i;
            maxc = c;
        }
    }
    *path = maxc;
    return maxi;
}

int main() {
    uint64_t maxi, maxc;

    maxi = sequence(1000000, &maxc);
    printf("%llu, %llu\n", maxi, maxc);
    return 0;
}

Here we compare n > 2 because the process may stop at 2 instead of 1 if the total length of the sequence is odd.

[EDIT:]

Let`s translate this into assembly!

See the C and an improved/bugfixed version of the asm by Peter Cordes on Godbolt. (editor's note: Sorry for putting my stuff in your answer, but my answer hit the 30k char limit from Godbolt links + text!)

The strategy of the accepted answer is correct, but here's a generalized example that works with the current version of React and Material-UI.

The flow of data should be one-way:

• the initialState is initialized in the constructor of the MyForm control
• the TextAreas are populated from this initial state
• changes to the TextAreas are propagated to the state via the handleChange callback.
• the state is accessed from the onClick callback---right now it just writes to the console. If you want to add validation it could go there.

import * as React from "react";
import TextField from "material-ui/TextField";
import RaisedButton from "material-ui/RaisedButton";

const initialState = {
    error: null, // you could put error messages here if you wanted
    person: {
        firstname: "",
        lastname: ""
    }
};

export class MyForm extends React.Component {

    constructor(props) {
        super(props);
        this.state = initialState;
        // make sure the "this" variable keeps its scope
        this.handleChange = this.handleChange.bind(this);
        this.onClick = this.onClick.bind(this);
    }

    render() {
        return (
            <div>
                <div>{this.state.error}</div>
                <div>
                    <TextField
                        name="firstname"
                        value={this.state.person.firstname}
                        floatingLabelText="First Name"
                        onChange={this.handleChange}/>
                    <TextField
                        name="lastname"
                        value={this.state.person.lastname}
                        floatingLabelText="Last Name"
                        onChange={this.handleChange}/>
                </div>
                <div>
                    <RaisedButton onClick={this.onClick} label="Submit!" />
                </div>
            </div>
        );
    }

    onClick() {
        console.log("when clicking, the form data is:");
        console.log(this.state.person);
    }

    handleChange(event, newValue): void {
        event.persist(); // allow native event access (see: https://facebook.github.io/react/docs/events.html)
        // give react a function to set the state asynchronously.
        // here it's using the "name" value set on the TextField
        // to set state.person.[firstname|lastname].            
        this.setState((state) => state.person[event.target.name] = newValue);

    }

}


React.render(<MyForm />, document.getElementById('app'));

(Note: You may want to write one handleChange callback per MUI Component to eliminate that ugly event.persist() call.)

Actually there are three ways to enable full screnn, visit : https://developer.android.com/training/system-ui/immersive

but if you wanna get full screen when the activity is opened, just put this code in your_activity.java

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

private void hideSystemUI() {
    // Enables regular immersive mode.
    // For "lean back" mode, remove SYSTEM_UI_FLAG_IMMERSIVE.
    // Or for "sticky immersive," replace it with SYSTEM_UI_FLAG_IMMERSIVE_STICKY
    View decorView = getWindow().getDecorView();
    decorView.setSystemUiVisibility(
            View.SYSTEM_UI_FLAG_IMMERSIVE
            // Set the content to appear under the system bars so that the
            // content doesn't resize when the system bars hide and show.
            | View.SYSTEM_UI_FLAG_LAYOUT_STABLE
            | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
            | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
            // Hide the nav bar and status bar
            | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
            | View.SYSTEM_UI_FLAG_FULLSCREEN);
}

// Shows the system bars by removing all the flags
// except for the ones that make the content appear under the system bars.
private void showSystemUI() {
    View decorView = getWindow().getDecorView();
    decorView.setSystemUiVisibility(
            View.SYSTEM_UI_FLAG_LAYOUT_STABLE
            | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
            | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
}

I faced the same error, but only with files cloned from git that were assigned to a proprietary plugin. I realized that even after cloning the files from git, I needed to create a new project or import a project in eclipse and this resolved the error.

Don't call write.close() in writeToFile().

The other answers mostly use the flags for setSystemUiVisibility() method in View. However, this API is deprecated since Android 11. Check my article about modifying the system UI visibility for more information. The article also explains how to handle the cutouts properly or how to listen to the visibility changes.

Here are code snippets for showing / hiding system bars with the new API as well as the deprecated one for backward compatibility:

/**
 * Hides the system bars and makes the Activity "fullscreen". If this should be the default
 * state it should be called from [Activity.onWindowFocusChanged] if hasFocus is true.
 * It is also recommended to take care of cutout areas. The default behavior is that the app shows
 * in the cutout area in portrait mode if not in fullscreen mode. This can cause "jumping" if the
 * user swipes a system bar to show it. It is recommended to set [WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_NEVER],
 * call [showBelowCutout] from [Activity.onCreate]
 * (see [Android Developers article about cutouts](https://developer.android.com/guide/topics/display-cutout#never_render_content_in_the_display_cutout_area)).

Adding SHA1 keys from Eclipse/keytool helped me only when creating the app on FB, then after rebuilding I would always get the OP error.

What solved my issue was adding the key in the error message to the Facebook dashboard settings.

Go to tools >> nuget >> console and type:

Install-Package System.Configuration.ConfigurationManager 

If you want a specific version:

Install-Package System.Configuration.ConfigurationManager -Version 4.5.0

Your ConfigurationManager dll will now be imported and the code will begin to work.

When your activity is recreated after it was previously destroyed, you can recover your saved state from the Bundle that the system passes your activity. Both the onCreate() and onRestoreInstanceState() callback methods receive the same Bundle that contains the instance state information.

Because the onCreate() method is called whether the system is creating a new instance of your activity or recreating a previous one, you must check whether the state Bundle is null before you attempt to read it. If it is null, then the system is creating a new instance of the activity, instead of restoring a previous one that was destroyed.

static final String STATE_USER = "user";
private String mUser;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // Check whether we're recreating a previously destroyed instance
    if (savedInstanceState != null) {
        // Restore value of members from saved state
        mUser = savedInstanceState.getString(STATE_USER);
    } else {
        // Probably initialize members with default values for a new instance
        mUser = "NewUser";
    }
}

@Override
public void onSaveInstanceState(Bundle savedInstanceState) {
    savedInstanceState.putString(STATE_USER, mUser);
    // Always call the superclass so it can save the view hierarchy state
    super.onSaveInstanceState(savedInstanceState);
}

After watching the DevBytes video (by Roman Nurik) and reading the very last line in the docs, which says:

Note: If you like the auto-hiding behavior of IMMERSIVE_STICKY but need to show your own UI controls as well, just use IMMERSIVE combined with Handler.postDelayed() or something similar to re-enter immersive mode after a few seconds.

the answer, radu122 gave, worked for me. Just setup a handler and your will be good to go.

Here is the code which works for me:

@Override
protected void onResume() {
    super.onResume();
    executeDelayed();
}


private void executeDelayed() {
    Handler handler = new Handler();
    handler.postDelayed(new Runnable() {
        @Override
        public void run() {
            // execute after 500ms
            hideNavBar();
        }
    }, 500);
}


private void hideNavBar() {
    if (Build.VERSION.SDK_INT >= 19) {
        View v = getWindow().getDecorView();
        v.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                                | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                                | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                                | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                                | View.SYSTEM_UI_FLAG_FULLSCREEN
                                | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
    }
}

Google says "after a few seconds" - but I want to provide this functionality as soon as possible. Maybe I will change the value later, if I have to, I will update this answer.

Try:

$ rm YOUR_PROJECT_DIR/.metadata/.plugins/org.eclipse.core.resources/.snap

Original source: Job found still running after platform shutdown eclipse

And also check with your antivirus, in case of me its avast, its blocking me from accessing market place, so i disabled it for few mins and tried accessing market place from eclipse , it worked!!!

java.io.NotSerializableException can occur when you serialize an inner class instance because:

serializing such an inner class instance will result in serialization of its associated outer class instance as well

Serialization of inner classes (i.e., nested classes that are not static member classes), including local and anonymous classes, is strongly discouraged

I overlooked my ECLIPSE VERSION it was 64Bit and 3.6

I had to make sure it's 32Bit Eclipse, 32 Bit JVM so i uninstalled Eclipse & all JVM for clean start. Installed 32Bit JDK1.6 from here and 32Bit Eclipse from here

Simply specify the path to the libraries:

echo "-Djava.library.path=/usr/lib/jni/" >> /etc/eclipse.ini

I encountered difficulties with Roi-Kyi Bryant's solution when multiple add-ins tried to modify the ribbon. I also don't have admin access on my work-computer, which ruled out installing the Custom UI Editor. So, if you're in the same boat as me, here's an alternative example to customising the ribbon using only Excel. Note, my solution is derived from the Microsoft guide.

1. Create Excel file/files whose ribbons you want to customise. In my case, I've created two .xlam files, Chart Tools.xlam and Priveleged UDFs.xlam, to demonstrate how multiple add-ins can interact with the Ribbon.
2. Create a folder, with any folder name, for each file you just created.
3. Inside each of the folders you've created, add a customUI and _rels folder.
4. Inside each customUI folder, create a customUI.xml file. The customUI.xml file details how Excel files interact with the ribbon. Part 2 of the Microsoft guide covers the elements in the customUI.xml file.

My customUI.xml file for Chart Tools.xlam looks like this

<customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui" xmlns:x="sao">
  <ribbon>
    <tabs>
      <tab idQ="x:chartToolsTab" label="Chart Tools">

My customUI.xml file for Priveleged UDFs.xlam looks like this

5. For each file you created in Step 1, suffix a .zip to their file name. In my case, I renamed Chart Tools.xlam to Chart Tools.xlam.zip, and Privelged UDFs.xlam to Priveleged UDFs.xlam.zip.
6. Open each .zip file, and navigate to the _rels folder. Copy the .rels file to the _rels folder you created in Step 3. Edit each .rels file with a text editor. From the Microsoft guide

Between the final <Relationship> element and the closing <Relationships> element, add a line that creates a relationship between the document file and the customization file. Ensure that you specify the folder and file names correctly.

<Relationship Type="http://schemas.microsoft.com/office/2006/
  relationships/ui/extensibility" Target="/customUI/customUI.xml" 
  Id="customUIRelID" />

My .rels file for Chart Tools.xlam looks like this

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
    <Relationships xmlns="http://schemas.openxmlformats.org/package/2006/relationships">
        <Relationship Id="rId3" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/extended-properties" Target="docProps/app.xml"/><Relationship Id="rId2" Type="http://schemas.openxmlformats.org/package/2006/relationships/metadata/core-properties" Target="docProps/core.xml"/>
        <Relationship Id="rId1" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/officeDocument" Target="xl/workbook.xml"/>
        <Relationship Type="http://schemas.microsoft.com/office/2006/relationships/ui/extensibility" Target="/customUI/customUI.xml" Id="chartToolsCustomUIRel" />
    </Relationships>

My .rels file for Priveleged UDFs looks like this.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
    <Relationships xmlns="http://schemas.openxmlformats.org/package/2006/relationships">
        <Relationship Id="rId3" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/extended-properties" Target="docProps/app.xml"/><Relationship Id="rId2" Type="http://schemas.openxmlformats.org/package/2006/relationships/metadata/core-properties" Target="docProps/core.xml"/>
        <Relationship Id="rId1" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/officeDocument" Target="xl/workbook.xml"/>
        <Relationship Type="http://schemas.microsoft.com/office/2006/relationships/ui/extensibility" Target="/customUI/customUI.xml" Id="privelegedUDFsCustomUIRel" />
    </Relationships>

7. Replace the .rels files in each .zip file with the .rels file/files you modified in the previous step.
8. Copy and paste the .customUI folder you created into the home directory of the .zip file/files.
9. Remove the .zip file extension from the Excel files you created.
10. If you've created .xlam files, back in Excel, add them to your Excel add-ins.
11. If applicable, create callbacks in each of your add-ins. In Step 4, there are onAction keywords in my buttons. The onAction keyword indicates that, when the containing element is triggered, the Excel application will trigger the sub-routine encased in quotation marks directly after the onAction keyword. This is known as a callback. In my .xlam files, I have a module called CallBacks where I've included my callback sub-routines.

My CallBacks module for Chart Tools.xlam looks like

Option Explicit

Public Sub MoveChartWithRelativeLinksCallBack(ByRef control As IRibbonControl)
  MoveChartWithRelativeLinks
End Sub

Public Sub MoveChartToManySheetsWithRelativeLinksCallBack(ByRef control As IRibbonControl)
  MoveChartToManySheetsWithRelativeLinks
End Sub

Public Sub DeleteAllChartsInWorkbookSharingAnAddressCallBack(ByRef control As IRibbonControl)
  DeleteAllChartsInWorkbookSharingAnAddress
End Sub

My CallBacks module for Priveleged UDFs.xlam looks like

Option Explicit

Public Sub InitialisePrivelegedUDFsCallBack(ByRef control As IRibbonControl)
  ThisWorkbook.InitialisePrivelegedUDFs
End Sub

Public Sub DeInitialisePrivelegedUDFsCallBack(ByRef control As IRibbonControl)
  ThisWorkbook.DeInitialisePrivelegedUDFs
End Sub

Different elements have a different callback sub-routine signature. For buttons, the required sub-routine parameter is ByRef control As IRibbonControl. If you don't conform to the required callback signature, you will receive an error while compiling your VBA project/projects. Part 3 of the Microsoft guide defines all the callback signatures.

Here's what my finished example looks like

Some closing tips

1. If you want add-ins to share Ribbon elements, use the idQ and xlmns: keyword. In my example, the Chart Tools.xlam and Priveleged UDFs.xlam both have access to the elements with idQ's equal to x:chartToolsTab and x:privelgedUDFsTab. For this to work, the x: is required, and, I've defined its namespace in the first line of my customUI.xml file, <customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui" xmlns:x="sao">. The section Two Ways to Customize the Fluent UI in the Microsoft guide gives some more details.
2. If you want add-ins to access Ribbon elements shipped with Excel, use the isMSO keyword. The section Two Ways to Customize the Fluent UI in the Microsoft guide gives some more details.

Make the background image transparent/semi-transparent. If it's a solid coloured background just create a 1px by 1px image in fireworks or whatever and adjust its opacity...

Do you have the fullscreen theme set in the manifest?

android:theme="@android:style/Theme.NoTitleBar.Fullscreen"

I don't think you'll be able to go fullscreen without this.

I would use the following to add and remove the fullscreen flag:

// Hide status bar
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
// Show status bar
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

I found the fix you were looking for:

context.deleteDatabase("webview.db");
context.deleteDatabase("webviewCache.db");

For some reason Android makes a bad cache of the url which it keeps returning by accident instead of the new data you need. Sure, you could just delete the entries from the DB but in my case I am only trying to access one URL so blowing away the whole DB is easier.

And don't worry, these DBs are just associated with your app so you aren't clearing the cache of the whole phone.

An alternative approach would be installing Microsoft ODBC Driver 13, then replace SQLOLEDB with ODBC Driver 13 for SQL Server

Regards.

Consider this code:

enum value{a,b,c,d,e,f,g,h,i,j,l,m,n};
value s;
cout << sizeof(s) << endl;

It will give 4 as output. So no matter the number of elements an enum contains, its size is always fixed.

ln [-Ffhinsv] source_file [target_file]

    link, ln -- make links

        -s    Create a symbolic link.

    A symbolic link contains the name of the file to which it is linked. 

    An ln command appeared in Version 1 AT&T UNIX.

Most importantly, the he library example

he.encode('foo © bar ? baz ???? qux');
// ? 'foo © bar ≠ baz 𝌆 qux'

// Passing an `options` object to `encode`, to explicitly encode all symbols:
he.encode('foo © bar ? baz ???? qux', {

});

he.decode('foo © bar ≠ baz 𝌆 qux');
// ? 'foo © bar ? baz ???? qux'

This library would probably make your coding easier and better managed. It is popular, regularly updated and follows the HTML spec. It itself has no dependencies, as can be seen in the package.json

gradle supports ndk compilation by generating another Android.mk file with absolute paths to your sources. NDK supports absolute paths since r9 on OSX, r9c on Windows, so you need to upgrade your NDK to r9+.

You may run into other troubles as NDK support by gradle is preliminary. If so you can deactivate the ndk compilation from gradle by setting:

sourceSets.main {
    jni.srcDirs = []
    jniLibs.srcDir 'src/main/libs'
}

to be able to call ndk-build yourself and integrate libs from libs/.

btw, you have any issue compiling for x86 ? I see you haven't included it in your APP_ABI.

It happens that /etc/hosts file doesn't support wild card entries.

You'll have to use other services like dnsmasq. To enable it in dnsmasq, just edit dnsmasq.conf and add the following line:

address=/example.com/127.0.0.1

All of these answers miss one important point -- the n'th line is the n'th line in the file, and not the n'th row in the dataset. I have a situation where I download some antiquated stream gauge data from the USGS. The head of the dataset is commented with '#', the first line after that are the labels, next comes a line that describes the date types, and last the data itself. I never know how many comment lines there are, but I know what the first couple of rows are. Example:

----------------------------- WARNING ----------------------------------

Some of the data that you have obtained from this U.S. Geological Survey database

may not have received Director's approval. ... agency_cd site_no datetime tz_cd 139719_00065 139719_00065_cd

5s 15s 20d 6s 14n 10s USGS 08041780 2018-05-06 00:00 CDT 1.98 A

It would be nice if there was a way to automatically skip the n'th row as well as the n'th line.

As a note, I was able to fix my issue with:

import pandas as pd
ds = pd.read_csv(fname, comment='#', sep='\t', header=0, parse_dates=True)
ds.drop(0, inplace=True)

Introduction

It represents the scope (the lifetime) of the bean. This is easier to understand if you are familiar with "under the covers" working of a basic servlet web application: How do servlets work? Instantiation, sessions, shared variables and multithreading.

@Request/View/Flow/Session/ApplicationScoped

A @RequestScoped bean lives as long as a single HTTP request-response cycle (note that an Ajax request counts as a single HTTP request too). A @ViewScoped bean lives as long as you're interacting with the same JSF view by postbacks which call action methods returning null/void without any navigation/redirect. A @FlowScoped bean lives as long as you're navigating through the specified collection of views registered in the flow configuration file. A @SessionScoped bean lives as long as the established HTTP session. An @ApplicationScoped bean lives as long as the web application runs. Note that the CDI @Model is basically a stereotype for @Named @RequestScoped, so same rules apply.

Which scope to choose depends solely on the data (the state) the bean holds and represents. Use @RequestScoped for simple and non-ajax forms/presentations. Use @ViewScoped for rich ajax-enabled dynamic views (ajaxbased validation, rendering, dialogs, etc). Use @FlowScoped for the "wizard" ("questionnaire") pattern of collecting input data spread over multiple pages. Use @SessionScoped for client specific data, such as the logged-in user and user preferences (language, etc). Use @ApplicationScoped for application wide data/constants, such as dropdown lists which are the same for everyone, or managed beans without any instance variables and having only methods.

Abusing an @ApplicationScoped bean for session/view/request scoped data would make it to be shared among all users, so anyone else can see each other's data which is just plain wrong. Abusing a @SessionScoped bean for view/request scoped data would make it to be shared among all tabs/windows in a single browser session, so the enduser may experience inconsitenties when interacting with every view after switching between tabs which is bad for user experience. Abusing a @RequestScoped bean for view scoped data would make view scoped data to be reinitialized to default on every single (ajax) postback, causing possibly non-working forms (see also points 4 and 5 here). Abusing a @ViewScoped bean for request, session or application scoped data, and abusing a @SessionScoped bean for application scoped data doesn't affect the client, but it unnecessarily occupies server memory and is plain inefficient.

Note that the scope should rather not be chosen based on performance implications, unless you really have a low memory footprint and want to go completely stateless; you'd need to use exclusively @RequestScoped beans and fiddle with request parameters to maintain the client's state. Also note that when you have a single JSF page with differently scoped data, then it's perfectly valid to put them in separate backing beans in a scope matching the data's scope. The beans can just access each other via @ManagedProperty in case of JSF managed beans or @Inject in case of CDI managed beans.

• Difference between View and Request scope in managed beans
• Advantages of using JSF Faces Flow instead of the normal navigation system
• Communication in JSF2 - Managed bean scopes

@CustomScoped/NoneScoped/Dependent

It's not mentioned in your question, but (legacy) JSF also supports @CustomScoped and @NoneScoped, which are rarely used in real world. The @CustomScoped must refer a custom Map<K, Bean> implementation in some broader scope which has overridden Map#put() and/or Map#get() in order to have more fine grained control over bean creation and/or destroy.

The JSF @NoneScoped and CDI @Dependent basically lives as long as a single EL-evaluation on the bean. Imagine a login form with two input fields referring a bean property and a command button referring a bean action, thus with in total three EL expressions, then effectively three instances will be created. One with the username set, one with the password set and one on which the action is invoked. You normally want to use this scope only on beans which should live as long as the bean where it's being injected. So if a @NoneScoped or @Dependent is injected in a @SessionScoped, then it will live as long as the @SessionScoped bean.

• What is the default Managed Bean Scope in a JSF 2 application?

Flash scope

As last, JSF also supports the flash scope. It is backed by a short living cookie which is associated with a data entry in the session scope. Before the redirect, a cookie will be set on the HTTP response with a value which is uniquely associated with the data entry in the session scope. After the redirect, the presence of the flash scope cookie will be checked and the data entry associated with the cookie will be removed from the session scope and be put in the request scope of the redirected request. Finally the cookie will be removed from the HTTP response. This way the redirected request has access to request scoped data which was been prepared in the initial request.

This is actually not available as a managed bean scope, i.e. there's no such thing as @FlashScoped. The flash scope is only available as a map via ExternalContext#getFlash() in managed beans and #{flash} in EL.

• How to show faces message in the redirected page

Aside from @Verhás István answer (which I like), I was expecting a one-liner for the question:

${project.reporting.outputDirectory} resolves to target/site in your project.

This works for plain BSD so it should be universally compatible with all flavors. Below.e.g in pwd ( . )

find . -size 0 |  xargs rm

Here is a simple solution for a simple feature:

.toJSON() Method

Instead of a JSON serializable class, implement a serializer method:

import json

class Object:
    def toJSON(self):
        return json.dumps(self, default=lambda o: o.__dict__, 
            sort_keys=True, indent=4)

So you just call it to serialize:

me = Object()
me.name = "Onur"
me.age = 35
me.dog = Object()
me.dog.name = "Apollo"

print(me.toJSON())

will output:

{
    "age": 35,
    "dog": {
        "name": "Apollo"
    },
    "name": "Onur"
}

You should install PDO on your server. Edit your php.ini (look at your phpinfo(), "Loaded Configuration File" line, to find the php.ini file path). Find and uncomment the following line (remove the ; character):

;extension=pdo_mysql.so

Then, restart your Apache server. For more information, please read the documentation.

This link was exactly what I was searching for .

Let me summarize the answers for others' benefit (for python and notepad++)

1) Ctrl+K on multiple lines (i.e. selected region) allows you to block comment.

Also note that pressing the combination multiple times allows you to add multiple "#"s (sometimes I use that while testing to differentiate from other comments)

2) Ctrl+Shift+K (on the commented region) allows you to perform block uncomment

3) Ctrl+Shift+K on an uncommented selected region does not comment it

4) Ctrl+Q allows you to block comment/uncomment in a toggled mode (meaning, you cannot add multiple '#'s like in 1) )

Hope this helps another wandering soul.

Question - how would you develop a hack of keyboard combinations to comment/uncomment if there were no shortcuts? Just curious. I've no clue hence asking.

cout << fixed << setprecision(2) << total;

setprecision specifies the minimum precision. So

cout << setprecision (2) << 1.2; 

will print 1.2

fixed says that there will be a fixed number of decimal digits after the decimal point

cout << setprecision (2) << fixed << 1.2;

will print 1.20

The simplest way to do this, if all you want is pinch zooming, is to place your image inside a UIWebView (write small amount of html wrapper code, reference your image, and you're basically done). The more complcated way to do this is to use touchesBegan, touchesMoved, and touchesEnded to keep track of the user's fingers, and adjust your view's transform property appropriately.

One case I recently encountered that required manual calls to GC.Collect() was when working with large C++ objects that were wrapped in tiny managed C++ objects, which in turn were accessed from C#.

The garbage collector never got called because the amount of managed memory used was negligible, but the amount of unmanaged memory used was huge. Manually calling Dispose() on the objects would require that I keep track of when objects are no longer needed myself, whereas calling GC.Collect() will clean up any objects that are no longer referred.....

Under Apache 2+ you can simply do as below (Using Linux Terminal):

You can't actually do the job quite right with toLowerCase, either on a string or in a character. The problem is that there are variant glyphs in either upper or lower case, and depending on whether you uppercase or lowercase your glyphs may or may not be preserved. It's not even clear what you mean when you say that two variants of a lower-case glyph are compared ignoring case: are they or are they not the same? (Note that there are also mixed-case glyphs: \u01c5, \u01c8, \u01cb, \u01f2 or ?, ?, ?, ?, but any method suggested here will work on those as long as they should count as the same as their fully upper or full lower case variants.)

There is an additional problem with using Char: there are some 80 code points not representable with a single Char that are upper/lower case variants (40 of each), at least as detected by Java's code point upper/lower casing. You therefore need to get the code points and change the case on these.

But code points don't help with the variant glyphs.

Anyway, here's a complete list of the glyphs that are problematic due to variants, showing how they fare against 6 variant methods:

1. Character toLowerCase
2. Character toUpperCase
3. String toLowerCase
4. String toUpperCase
5. String equalsIgnoreCase
6. Character toLowerCase(toUpperCase) (or vice versa)

For these methods, S means that the variants are treated the same as each other, D means the variants are treated as different from each other.

Complicating this still further is that there is no way to get the Turkish I's right (i.e. the dotted versions are different than the undotted versions) unless you know you're in Turkish; none of these methods give correct behavior and cannot unless you know the locale (i.e. non-Turkish: i and I are the same ignoring case; Turkish, not).

Overall, using toUpperCase gives you the closest approximation, since you have only five uppercase variants (or four, not counting Turkish).

You can also try to specifically intercept those five troublesome cases and call toUpperCase(toLowerCase(c)) on them alone. If you choose your guards carefully (just toUpperCase if c < 0x130 || c > 0x212B, then work through the other alternatives) you can get only a ~20% speed penalty for characters in the low range (as compared to ~4x if you convert single characters to strings and equalsIgnoreCase them) and only about a 2x penalty if you have a lot in the danger zone. You still have the locale problem with dotted I, but otherwise you're in decent shape. Of course if you can use equalsIgnoreCase on a larger string, you're better off doing that.

Here is sample Scala code that does the job:

def elevateCase(c: Char): Char = {
  if (c < 0x130 || c > 0x212B) Character.toUpperCase(c)
  else if (c == 0x130 || c == 0x3F4 || c == 0x2126 || c >= 0x212A)
    Character.toUpperCase(Character.toLowerCase(c))
  else Character.toUpperCase(c)
}

Instead of looking at the source code, you should read the javadoc String.format() and Formatter syntax.

You specify the format of the value after the %. For instance for decimal integer it is d, and for String it is s:

String aString = "world";
int aInt = 20;
String.format("Hello, %s on line %d",  aString, aInt );

Output:

Hello, world on line 20

To do what you tried (use an argument index), you use: *n*$,

String.format("Line:%2$d. Value:%1$s. Result: Hello %1$s at line %2$d", aString, aInt );

Output:

Line:20. Value:world. Result: Hello world at line 20

"hard coding" means putting something into your source code. If you are not hard coding, then you do something like prompting the user for the data, or allow the user to put the data on the command line, or something like that.

So, to hard code the location of the file as being on the C: drive, you would just put the pathname of the file all together in your source code.

Here is an example.

int main()
{
    const char *filename = "C:\\myfile.txt";

    printf("Filename is: %s\n", filename);
}

The file name is "hard coded" as: C:\myfile.txt

The reason the backslash is doubled is because backslashes are special in C strings.

If you want to reset it, then simple use:

<input type="reset" value="Reset" />

But beware, it will not clear out textboxes that have default value. For example, if we have the following textboxes and by default, they have the following values:

<input id="textfield1" type="text" value="sample value 1" />
<input id="textfield2" type="text" value="sample value 2" />

So, to clear it out, compliment it with javascript:

function clearText()  
{
    document.getElementById('textfield1').value = "";
    document.getElementById('textfield2').value = "";
}  

And attach it to onclick of the reset button:
<input type="reset" value="Reset" onclick="clearText()" />

You could also use the php native funcion get_browser()

IMPORTANT NOTE: You should have a browscap.ini file.

The error is due the fact that you are passing a wrong to strcat(). Look at strcat()'s prototype:

   char *strcat(char *dest, const char *src);

But you pass char as the second argument, which is obviously wrong.

Use snprintf() instead.

char str[1024] = "Hello World";
char tmp = '.';
size_t len = strlen(str);

snprintf(str + len, sizeof str - len, "%c", tmp);

As commented by OP:

That was just a example with Hello World to describe the Problem. It must be empty as first in my real program. Program will fill it later. The problem just contains to add a char/int to an char Array

In that case, snprintf() can handle it easily to "append" integer types to a char buffer too. The advantage of snprintf() is that it's more flexible to concatenate various types of data into a char buffer.

For example to concatenate a string, char and an int:

char str[1024];
ch tmp = '.';
int i = 5;

// Fill str here

snprintf(str + len, sizeof str - len, "%c%d", str, tmp, i);

The warning comes up because Tomcat scans all Jars for TLDs (Tagging Library Definitions).

Step1: To see which JARs are throwing up this warning, insert he following line to tomcat/conf/logging.properties

Now you should be able to see warnings with a detail of which JARs are causing the intial warning

Step2 Since skipping unneeded JARs during scanning can improve startup time and JSP compilation time, we will skip un-needed JARS in the catalina.properties file. You have two options here -

1. List all the JARs under the tomcat.util.scan.StandardJarScanFilter.jarsToSkip. But this can get cumbersome if you have a lot jars or if the jars keep changing.
2. Alternatively, Insert tomcat.util.scan.StandardJarScanFilter.jarsToSkip=* to skip all the jars

You should now not see the above warnings and if you have a considerably large application, it should save you significant time in deploying an application.

w.winfo_children()
Returns a list of all w's children, in their stacking order from lowest (bottom) to highest (top).

for widget in frame.winfo_children():
    widget.destroy()

Will destroy all the widget in your frame. No need for a second frame.

Two example works for me, for your reference.

Bitmap bitmap = Utils.decodeBase64(base64);
try {
    File file = new File(filePath);
    FileOutputStream fOut = new FileOutputStream(file);
    bitmap.compress(Bitmap.CompressFormat.PNG, 85, fOut);
    fOut.flush();
    fOut.close();
}
catch (Exception e) {
    e.printStackTrace();
    LOG.i(null, "Save file error!");
    return false;
}

and this one

Bitmap savePic = Utils.decodeBase64(base64);
File file = new File(filePath);
File path = new File(file.getParent());

if (savePic != null) {
    try {
        // build directory
        if (file.getParent() != null && !path.isDirectory()) {
            path.mkdirs();
        }
        // output image to file
        FileOutputStream fos = new FileOutputStream(filePath);
        savePic.compress(Bitmap.CompressFormat.PNG, 90, fos);
        fos.close();
        ret = true;
    } catch (Exception e) {
        e.printStackTrace();
    }
} else {
    LOG.i(TAG, "savePicture image parsing error");
}

There's one more theoretical possibility to do it: professional versions of Windows have built-in POSIX support, so bash could have been compiled for Windows natively.

Pity, but I still haven't found a compiled one myself...

Take me to [pookie](#pookie)

should be the correct markdown syntax to jump to the anchor point named pookie.

To insert an anchor point of that name use HTML:

<a name="pookie"></a>

Markdown doesn't seem to mind where you put the anchor point. A useful place to put it is in a header. For example:

### <a name="tith"></a>This is the Heading

works very well. (I'd demonstrate here but SO's renderer strips out the anchor.)

Note on self-closing tags and id= versus name=

An earlier version of this post suggested using <a id='tith' />, using the self-closing syntax for XHTML, and using the id attribute instead of name.

XHTML allows for any tag to be 'empty' and 'self-closed'. That is, <tag /> is short-hand for <tag></tag>, a matched pair of tags with an empty body. Most browsers will accept XHTML, but some do not. To avoid cross-browser problems, close the tag explicitly using <tag></tag>, as recommended above.

Finally, the attribute name= was deprecated in XHTML, so I originally used id=, which everyone recognises. However, HTML5 now creates a global variable in JavaScript when using id=, and this may not necessarily be what you want. So, using name= is now likely to be more friendly.

(Thanks to Slipp Douglas for explaining XHTML to me, and nailer for pointing out the HTML5 side-effect — see the comments and nailer's answer for more detail. name= appears to work everywhere, though it is deprecated in XHTML.)

When you read in git tag man page:

One important aspect of git is it is distributed, and being distributed largely means there is no inherent "upstream" or "downstream" in the system.

, that simply means there is no absolute upstream repo or downstream repo.
Those notions are always relative between two repos and depends on the way data flows:

If "yourRepo" has declared "otherRepo" as a remote one, then:

• you are pulling from upstream "otherRepo" ("otherRepo" is "upstream from you", and you are "downstream for otherRepo").
• you are pushing to upstream ("otherRepo" is still "upstream", where the information now goes back to).

Note the "from" and "for": you are not just "downstream", you are "downstream from/for", hence the relative aspect.

The DVCS (Distributed Version Control System) twist is: you have no idea what downstream actually is, beside your own repo relative to the remote repos you have declared.

• you know what upstream is (the repos you are pulling from or pushing to)
• you don't know what downstream is made of (the other repos pulling from or pushing to your repo).

Basically:

In term of "flow of data", your repo is at the bottom ("downstream") of a flow coming from upstream repos ("pull from") and going back to (the same or other) upstream repos ("push to").

You can see an illustration in the git-rebase man page with the paragraph "RECOVERING FROM UPSTREAM REBASE":

It means you are pulling from an "upstream" repo where a rebase took place, and you (the "downstream" repo) is stuck with the consequence (lots of duplicate commits, because the branch rebased upstream recreated the commits of the same branch you have locally).

That is bad because for one "upstream" repo, there can be many downstream repos (i.e. repos pulling from the upstream one, with the rebased branch), all of them having potentially to deal with the duplicate commits.

Again, with the "flow of data" analogy, in a DVCS, one bad command "upstream" can have a "ripple effect" downstream.

Note: this is not limited to data.
It also applies to parameters, as git commands (like the "porcelain" ones) often call internally other git commands (the "plumbing" ones). See rev-parse man page:

Many git porcelainish commands take mixture of flags (i.e. parameters that begin with a dash '-') and parameters meant for the underlying git rev-list command they use internally and flags and parameters for the other commands they use downstream of git rev-list. This command is used to distinguish between them.

You should be able to install from NuGet (http://www.nuget.org/packages/Microsoft.AspNet.Mvc) into VS2012. Change the Target Framework to .NET 4.5.

Not sure the new project templates are ready for VS2012. But if you have an ASP.NET MVC 4 app you can upgrade using the link below.

This might look stupid, but check if you haven't already added the folder/files you are trying to ignore to the index before. If you did, it does not matter what you put in your .gitignore file, the folders/files will still be staged.

One that I use often:

 Integer.parseInt("1234");

Point is, there are plenty of ways to do this, all equally valid. As to which is most optimum/efficient, you'd have to ask someone else.

According to the standard, you should be safe with that assumption. The C++ bool type has two values - true and false with corresponding values 1 and 0.

The thing to watch about for is mixing bool expressions and variables with BOOL expression and variables. The latter is defined as FALSE = 0 and TRUE != FALSE, which quite often in practice means that any value different from 0 is considered TRUE.

A lot of modern compilers will actually issue a warning for any code that implicitly tries to cast from BOOL to bool if the BOOL value is different than 0 or 1.

The onclick property is all lower-case, and accepts a function, not a string.

document.getElementById("test").onclick = foo2;

See also addEventListener.

Use +=

$val = 0;

foreach($arr as $var) {
   $val += $var; 
}

echo $val;

With async: false you get yourself a blocked browser. For a non blocking synchronous solution you can use the following:

ES6/ECMAScript2015

With ES6 you can use a generator & the co library:

beforecreate: function (node, targetNode, type, to) {
    co(function*(){  
        let result = yield jQuery.get('http://example.com/catalog/create/' + targetNode.id + '?name=' + encode(to.inp[0].value));
        //Just use the result here
    });
}

ES7

With ES7 you can just use asyc await:

beforecreate: function (node, targetNode, type, to) {
    (async function(){
        let result = await jQuery.get('http://example.com/catalog/create/' + targetNode.id + '?name=' + encode(to.inp[0].value));
        //Just use the result here
    })(); 
}

The problem occurred because of wrong table type.MyISAM is the only type of table that Mysql supports for Full-text indexes.

To correct this error run following sql.

 CREATE TABLE gamemech_chat (
  id bigint(20) unsigned NOT NULL auto_increment,
  from_userid varchar(50) NOT NULL default '0',
  to_userid varchar(50) NOT NULL default '0',
  text text NOT NULL,
  systemtext text NOT NULL,
  timestamp datetime NOT NULL default '0000-00-00 00:00:00',
  chatroom bigint(20) NOT NULL default '0',
  PRIMARY KEY  (id),
  KEY from_userid (from_userid),
  FULLTEXT KEY from_userid_2 (from_userid),
  KEY chatroom (chatroom),
  KEY timestamp (timestamp)
) ENGINE=MyISAM;

You need to include inttypes.h if you want all those nifty new format specifiers for the intN_t types and their brethren, and that is the correct (ie, portable) way to do it, provided your compiler complies with C99. You shouldn't use the standard ones like %d or %u in case the sizes are different to what you think.

It includes stdint.h and extends it with quite a few other things, such as the macros that can be used for the printf/scanf family of calls. This is covered in section 7.8 of the ISO C99 standard.

For example, the following program:

#include <stdio.h>
#include <inttypes.h>
int main (void) {
    uint32_t a=1234;
    uint16_t b=5678;
    printf("%" PRIu32 "\n",a);
    printf("%" PRIu16 "\n",b);
    return 0;
}

outputs:

1234
5678

In situations where the class under test can be modified and when it's desirable to avoid byte code manipulation, to keep things fast or to minimise third party dependencies, here is my take on the use of a factory to extract the new operation.

public class TestedClass {

    interface PojoFactory { Pojo getNewPojo(); }

    private final PojoFactory factory;

    /** For use in production - nothing needs to change. */
    public TestedClass() {
        this.factory = new PojoFactory() {
            @Override
            public Pojo getNewPojo() {
                return new Pojo();
            }
        };
    }

    /** For use in testing - provide a pojo factory. */
    public TestedClass(PojoFactory factory) {
        this.factory = factory;
    }

    public void doSomething() {
        Pojo pojo = this.factory.getNewPojo();
        anythingCouldHappen(pojo);
    }
}

With this in place, your testing, asserts and verify calls on the Pojo object are easy:

public  void testSomething() {
    Pojo testPojo = new Pojo();
    TestedClass target = new TestedClass(new TestedClass.PojoFactory() {
                @Override
                public Pojo getNewPojo() {
                    return testPojo;
                }
            });
    target.doSomething();
    assertThat(testPojo.isLifeStillBeautiful(), is(true));
}

The only downside to this approach potentially arises if TestClass has multiple constructors which you'd have to duplicate with the extra parameter.

For SOLID reasons you'd probably want to put the PojoFactory interface onto the Pojo class instead, and the production factory as well.

public class Pojo {

    interface PojoFactory { Pojo getNewPojo(); }

    public static final PojoFactory productionFactory = 
        new PojoFactory() {
            @Override 
            public Pojo getNewPojo() {
                return new Pojo();
            }
        };

The direct replacement is if/elif/else.

However, in many cases there are better ways to do it in Python. See "Replacements for switch statement in Python?".

Adding this just as an addition to @jimt's excellent answer:

one common way to define it all at initialization time is using an anonymous struct:

var opts = []struct {
    shortnm      byte
    longnm, help string
    needArg      bool
}{
    {'a', "multiple", "Usage for a", false},
    {
        shortnm: 'b',
        longnm:  "b-option",
        needArg: false,
        help:    "Usage for b",
    },
}

This is commonly used for testing as well to define few test cases and loop through them.

Html.Hidden and Html.HiddenFor used to generate name-value pairs which waited by action method in controller. Sample Usage(*):

@using (Html.BeginForm("RemoveFromCart", "Cart")) {
                    @Html.Hidden("ProductId", line.Product.ProductID)
                    @Html.HiddenFor(x => x.ReturnUrl)
                    <input class="btn btn-sm btn-warning"
                           type="submit" value="Remove" />
                }

If your action method wait for "ProductId" you have to generate this name in form via using (Html.Hidden or Html.HiddenFor) For the case it is not possible to generate this name with strongly typed model you simple write this name with a string thats "ProductId".

public ViewResult RemoveFromCart(int productId, string returnUrl){...}

If I had written Html.HiddenFor(x => line.Product.ProductID), the helper would render a hidden field with the name "line.Product.ProductID". The name of the field would not match the names of the parameters for the "RemoveFromCart" action method which waiting the name of "ProductId". This would prevent the default model binders from working, so the MVC Framework would not be able to call the method.

Don't use your browser to test your API.

Instead, try to use an HTTP client that allows you to specify your request, such as CURL, or even Fiddler.

The problem with this issue is in the client, not in the API. The web API behaves correctly, according to the browser's request.

Matt is asking about positional parameters in argparse, and I agree that the Python documentation is lacking on this aspect. There's not a single, complete example in the ~20 odd pages that shows both parsing and using positional parameters.

None of the other answers here show a complete example of positional parameters, either, so here's a complete example:

# tested with python 2.7.1
import argparse

parser = argparse.ArgumentParser(description="An argparse example")

parser.add_argument('action', help='The action to take (e.g. install, remove, etc.)')
parser.add_argument('foo-bar', help='Hyphens are cumbersome in positional arguments')

args = parser.parse_args()

if args.action == "install":
    print("You asked for installation")
else:
    print("You asked for something other than installation")

# The following do not work:
# print(args.foo-bar)
# print(args.foo_bar)

# But this works:
print(getattr(args, 'foo-bar'))

The thing that threw me off is that argparse will convert the named argument "--foo-bar" into "foo_bar", but a positional parameter named "foo-bar" stays as "foo-bar", making it less obvious how to use it in your program.

Notice the two lines near the end of my example -- neither of those will work to get the value of the foo-bar positional param. The first one is obviously wrong (it's an arithmetic expression args.foo minus bar), but the second one doesn't work either:

AttributeError: 'Namespace' object has no attribute 'foo_bar'

If you want to use the foo-bar attribute, you must use getattr, as seen in the last line of my example. What's crazy is that if you tried to use dest=foo_bar to change the property name to something that's easier to access, you'd get a really bizarre error message:

ValueError: dest supplied twice for positional argument

Here's how the example above runs:

$ python test.py
usage: test.py [-h] action foo-bar
test.py: error: too few arguments

$ python test.py -h
usage: test.py [-h] action foo-bar

An argparse example

positional arguments:
  action      The action to take (e.g. install, remove, etc.)
  foo-bar     Hyphens are cumbersome in positional arguments

optional arguments:
  -h, --help  show this help message and exit

$ python test.py install foo
You asked for installation
foo

This should work:

# apt-get install libusb-1.0-0-dev

Starting from Spring Boot version 1.2.0.RELEASE , there is a property you can add to your application.properties to set a default date format to all of your classes spring.jackson.date-format.

For your date format example, you would add this line to your properties file:

spring.jackson.date-format=yyyy-MM-dd

Reference https://docs.spring.io/spring-boot/docs/1.2.0.RELEASE/reference/html/common-application-properties.html

If you have a process that already generates and returns an Image type, you can alter the bind and not have to modify any additional image creation code.

Refer to the ".Source" of the image in the binding statement.

XAML

<Image Name="imgOpenClose" Source="{Binding ImageOpenClose.Source}"/>

View Model Field

private Image _imageOpenClose;
public Image ImageOpenClose
{
    get
    {
        return _imageOpenClose;
    }
    set
    {
        _imageOpenClose = value;
        OnPropertyChanged();
    }
}

Do the loop in the normal way, the java.util.ConcurrentModificationException is an error related to the elements that are accessed.

So try:

for(int i = 0; i < list.size(); i++){
    lista.get(i).action();
}

You can do two things to add animations, first you can let android animate layout changes for you. That way every time you change something in the layout like changing view visibility or view positions android will automatically create fade/transition animations. To use that set

android:animateLayoutChanges="true"

on the root node in your layout.

Your second option would be to manually add animations. For this I suggest you use the new animation API introduced in Android 3.0 (Honeycomb). I can give you a few examples:

This fades out a View:

view.animate().alpha(0.0f);

This fades it back in:

view.animate().alpha(1.0f);

This moves a View down by its height:

view.animate().translationY(view.getHeight());

This returns the View to its starting position after it has been moved somewhere else:

view.animate().translationY(0);

You can also use setDuration() to set the duration of the animation. For example this fades out a View over a period of 2 seconds:

view.animate().alpha(0.0f).setDuration(2000);

And you can combine as many animations as you like, for example this fades out a View and moves it down at the same time over a period of 0.3 seconds:

view.animate()
        .translationY(view.getHeight())
        .alpha(0.0f)
        .setDuration(300);

And you can also assign a listener to the animation and react to all kinds of events. Like when the animation starts, when it ends or repeats etc. By using the abstract class AnimatorListenerAdapter you don't have to implement all callbacks of AnimatorListener at once but only those you need. This makes the code more readable. For example the following code fades out a View moves it down by its height over a period of 0.3 seconds (300 milliseconds) and when the animation is done its visibility is set to View.GONE.

view.animate()
        .translationY(view.getHeight())
        .alpha(0.0f)
        .setDuration(300)
        .setListener(new AnimatorListenerAdapter() {
            @Override
            public void onAnimationEnd(Animator animation) {
                super.onAnimationEnd(animation);
                view.setVisibility(View.GONE);
            }
        });

 Step 1:

    Locate phpMyAdmin installation path.

    $cfg['Servers'][$i]['user'] = 'root';
    $cfg['Servers'][$i]['password'] = '';
    $cfg['Servers'][$i]['extension'] = 'mysqli';
    $cfg['Servers'][$i]['AllowNoPassword'] = true;
    $cfg['Lang'] = '';

You can write like that. This is for whenever you change context path you don't need to modify your jsp file.

<link rel="stylesheet" href="${pageContext.request.contextPath}/css/styles.css" />

The other answers do not answer the actual question, but rather provide workarounds which is a shame because it literally takes 10 seconds to figure out what the correct syntax for accepts parameter.

The accepts parameter takes an object which maps the dataType to the Accept header. In your case you don't need to even need to pass the accepts object, as setting the data type to json should be sufficient. However if you do want to configure a custom Accept header this is what you do:

accepts: {"*": "my custom mime type" },

How do I know? Open jquery's source code and search for "accepts". The very first find tells you all you need to know:

    accepts: {
        "*": allTypes,
        text: "text/plain",
        html: "text/html",
        xml: "application/xml, text/xml",
        json: "application/json, text/javascript"
    },

As you see the are default mappings to text, html, xml and json data types.

The current PyGame release, 1.9.6 doesn't support Python 3.9. I fyou don't want to wait for PyGame 2.0, you have to use Python 3.8. Alternatively, you can install a developer version by explicitly specifying the version (2.0.0.dev20 is the latest release at the time of writing):

pip install pygame==2.0.0.dev20

or try to install a pre-release version by enabling the --pre option:

pip install pygame --pre

$('input.abc').not(':checked').length > 0

This should work

import { Router } from "@angular/router"

export class YourClass{

   constructor(private router: Router) { }

For those wondering if jQuery id selectors are slower than document.getElementById, the answer is yes, but not because of the preconception that it searches through the entire DOM looking for an element. jQuery does actually use the native method. It's actually because jQuery uses a regular expression first to separate out strings in the selector to check by, and of course running the constructor:

rquickExpr = /^(?:(<[\w\W]+>)[^>]*|#([\w-]*))$/

Whereas using a DOM element as an argument returns immediately with 'this'.

So this:

$(document.getElementById('blah')).doSomething();

Will always be faster than this:

$('#blah').doSomething();

My suggestion would be to finish the activity that you don't want the users to go back to. For instance, in your sign in activity, right after you call startActivity, call finish(). When the users hit the back button, they will not be able to go to the sign in activity because it has been killed off the stack.

Here's another take based on @dfa's and @scottb's answers that handles any non-letter/digit characters:

public final class TitleCase {

    public static String toTitleCase(String input) {

        StringBuilder titleCase = new StringBuilder(input.length());
        boolean nextTitleCase = true;

        for (char c : input.toLowerCase().toCharArray()) {
            if (!Character.isLetterOrDigit(c)) {
                nextTitleCase = true;
            } else if (nextTitleCase) {
                c = Character.toTitleCase(c);
                nextTitleCase = false;
            }
            titleCase.append(c);
        }

        return titleCase.toString();
    }

}

Given input:

MARY ÄNN O’CONNEŽ-ŠUSLIK

the output is

Mary Änn O’Connež-Šuslik

        <table id="table_id" class="table table-hover">
          <thead>
            <tr>
             ...
             ...
            </tr>
          </thead>
        </table>

use this command to clear the body of that table: $("#table_id tbody").empty()

I use jquery to load the table content dynamically, and use this command to clear the body when doing the refreshing.

hope this helps you.

You can use following code for open actionSheet in Swift

        let alert = UIAlertController(title: enter your title, message: "Enter your messgage. ", preferredStyle: UIAlertControllerStyle.Alert)

        alert.addTextFieldWithConfigurationHandler(configurationTextField)

        alert.addAction(UIAlertAction(title: "Close", style: UIAlertActionStyle.Cancel, handler:{ (UIAlertAction)in

Use

git cherry-pick <commit-hash>

So this will pick your behind commit to git location you are on.

var dataString = "flag=fetchmediaaudio&id="+id;

$.ajax

  type: "POST",
  url: "ajax.php",
  data: dataString,
  success: function(html)
  {
     alert(html);
  }
});

Apart from the settings explained in the answer by @DarkNeuron:

"files.encoding": "any encoding"

you can also specify settings for a specific language like so:

"[language id]": {
  "files.encoding": "any encoding"
}

For example, I use this when I need to edit PowerShell files previously created with ISE (which are created in ANSI format):

"[powershell]": {
    "files.encoding": "windows1252"
}

You can get a list of identifiers of well-known languages here.

Google Map V2

The following solution works for Android Marshmallow 6 (API 23, API 24, API 25, API 26, API 27, API 28). It also works in Xamarin.

LatLngBounds.Builder builder = new LatLngBounds.Builder();

//the include method will calculate the min and max bound.
builder.include(marker1.getPosition());
builder.include(marker2.getPosition());
builder.include(marker3.getPosition());
builder.include(marker4.getPosition());

LatLngBounds bounds = builder.build();

int width = getResources().getDisplayMetrics().widthPixels;
int height = getResources().getDisplayMetrics().heightPixels;
int padding = (int) (width * 0.10); // offset from edges of the map 10% of screen

CameraUpdate cu = CameraUpdateFactory.newLatLngBounds(bounds, width, height, padding);

mMap.animateCamera(cu);

The keypad will allow the keyboard of the user's terminal to allow for function keys to be interpreted as a single value (i.e. no escape sequence).

As stated in the man page:

The keypad option enables the keypad of the user's terminal. If enabled (bf is TRUE), the user can press a function key (such as an arrow key) and wgetch returns a single value representing the function key, as in KEY_LEFT. If disabled (bf is FALSE), curses does not treat function keys specially and the program has to interpret the escape sequences itself. If the keypad in the terminal can be turned on (made to transmit) and off (made to work locally), turning on this option causes the terminal keypad to be turned on when wgetch is called. The default value for keypad is false.

My favorite way to do this is with an extension function called 'Map':

public static void Map<T>(this IEnumerable<T> source, Action<T> func)
{
    foreach (T i in source)
        func(i);
}

Then you can add all the rows like so:

X.Map(item => this.dataGridView1.Rows.Add(item.ID, item.Name));

this should be on here: it works anyway. And it looks good compared to the above ones.

hlsl code

        float3 Hue(float H)
        {
            half R = abs(H * 6 - 3) - 1;
            half G = 2 - abs(H * 6 - 2);
            half B = 2 - abs(H * 6 - 4);
            return saturate(half3(R,G,B));
        }

        half4 HSVtoRGB(in half3 HSV)
        {
            return half4(((Hue(HSV.x) - 1) * HSV.y + 1) * HSV.z,1);
        }

float3 is 16 bit precision vector3 data type, i.e. float3 hue() is returns a data type (x,y,z) e.g. (r,g,b), half is same with half precision, 8bit, a float4 is (r,g,b,a) 4 values.

The header function is used to send HTTP response headers back to the user (i.e. you cannot use it to create request headers.

May I ask why are you doing this? Why simulate a POST request when you can just right there and then act on the data someway? I'm assuming of course script.php resides on your server.

To create a POST request, open a up a TCP connection to the host using fsockopen(), then use fwrite() on the handler returned from fsockopen() with the same values you used in the header functions in the OP. Alternatively, you can use cURL.

This can occur because of you are trying to checking out the repository by accessing it via a proxy server without enabling the proxy server in the place you need to change the settings in TortoiseSvn. So if you are using a proxy server make sure that you put a tick in "Enable Proxy Server" in Settings->Network and give your Server address and Port number in the relevant places. Now try to check out again.

Following the instructions given by 'cfi' works for me, although there are a few pieces they left out that you might need:

1) Your lapack directory, after unzipping, may be called lapack-X-Y (some version number), so you can just rename that to LAPACK.

cd ~/src
mv lapack-[tab] LAPACK

2) In that directory, you may need to do:

cd ~/src/LAPACK 
cp lapack_LINUX.a libflapack.a

To get the most recent tag (example output afterwards):

git describe --tags --abbrev=0   # 0.1.0-dev

To get the most recent tag, with the number of additional commits on top of the tagged object & more:

git describe --tags              # 0.1.0-dev-93-g1416689

To get the most recent annotated tag:

git describe --abbrev=0

From the API consumer's perspective, the endpoints should be predictable so

Ideally...

1. GET /resources should return a list of resources.
2. GET /resource should return a 400 level status code.
3. GET /resources/id/{resourceId} should return a collection with one resource.
4. GET /resource/id/{resourceId} should return a resource object.
5. POST /resources should batch create resources.
6. POST /resource should create a resource.
7. PUT /resource should update a resource object.
8. PATCH /resource should update a resource by posting only the changed attributes.
9. PATCH /resources should batch update resources posting only the changed attributes.
10. DELETE /resources should delete all resources; just kidding: 400 status code
11. DELETE /resource/id/{resourceId}

This approach is the most flexible and feature rich, but also the most time consuming to develop. So, if you're in a hurry (which is always the case with software development) just name your endpoint resource or the plural form resources. I prefer the singular form because it gives you the option to introspect and evaluate programmatically since not all plural forms end in 's'.

Having said all that, for whatever reason the most commonly used practice developer's have chosen is to use the plural form. This is ultimately the route I have chosen and if you look at popular apis like github and twitter, this is what they do.

Some criteria for deciding could be:

1. What are my time constraints?
2. What operations will I allow my consumers to do?
3. What does the request and result payload look like?
4. Do I want to be able to use reflection and parse the URI in my code?

So it's up to you. Just whatever you do be consistent.

I execute this code for ODD & EVEN:

#include <stdio.h>
int main()
{
    int number;
    printf("Enter an integer: ");
    scanf("%d", &number);

    if(number % 2 == 0)
        printf("%d is even.", number);
    else
        printf("%d is odd.", number);
}

Add new socket connections to an array and then when you want to close all - loop through them and disconnect. (server side)

var socketlist = [];

   io.sockets.on('connection', function (socket) {
        socketlist.push(socket);  
        //...other code for connection here..
   });


    //close remote sockets
    socketlist.forEach(function(socket) {        
        socket.disconnect();                      
    });    

Embed in a stack view. Stack view is a component recently added by Apple in their iOS SDK to reflect grid based implementations in java script web based front end libraries such as bootstrap.

The gap between the (bootstrap) input field and jquery-ui autocompleter seem to occur only in jQuery versions >= 3.2

When using jQuery version 3.1.1 it seem to not happen.

Possible reason is the notable update in v3.2.0 related to a bug fix on .width() and .height(). Check out the jQuery release notes for further details: v3.2.0 / v3.1.1

Bootstrap version 3.4.1 and jquery-ui version 1.12.0 used

I compare strings using = and not <>. I've found out that in this context = seems to work in more reasonable fashion than <>. I have specified that two empty (or NULL) strings are equal. The real implementation returns PL/SQL boolean, but here I changed that to pls_integer (0 is false and 1 is true) to be able easily demonstrate the function.

create or replace function is_equal(a in varchar2, b in varchar2)
return pls_integer as
begin
  if a is null and b is null then
    return 1;
  end if;

  if a = b then
    return 1;
  end if;

  return 0;
end;

show errors

begin
  /* Prints 0 */
  dbms_output.put_line(is_equal('AAA', 'BBB'));
  dbms_output.put_line(is_equal('AAA', null));
  dbms_output.put_line(is_equal(null, 'BBB'));
  dbms_output.put_line(is_equal('AAA', ''));
  dbms_output.put_line(is_equal('', 'BBB'));

  /* Prints 1 */
  dbms_output.put_line(is_equal(null, null));
  dbms_output.put_line(is_equal(null, ''));
  dbms_output.put_line(is_equal('', ''));
  dbms_output.put_line(is_equal('AAA', 'AAA'));
end;

In my case, problem was due to low disk space. I want to mention it for other users like me :)

In my case, this error happened because my HTML had a trailing linebreak.

var myHtml = '<p>\
    This should work.\
    But does not.\
</p>\
';

jQuery('.something').append(myHtml); // this causes the error

To avoid the error, you just need to trim the HTML.

jQuery('.something').append(jQuery.trim(myHtml)); // this works

You might be interested in this query. It tells you how much space is allocated for each table taking into account the indexes and any LOBs on the table. Often you are interested to know "How much spaces the the Purchase Order table take, including any indexes" rather than just the table itself. You can always delve into the details. Note that this requires access to the DBA_* views.

COLUMN TABLE_NAME FORMAT A32
COLUMN OBJECT_NAME FORMAT A32

 FROM dba_segments
 WHERE segment_type IN ('TABLE', 'TABLE PARTITION', 'TABLE SUBPARTITION')
 UNION ALL
 SELECT i.table_name, i.owner, s.bytes

If only the columns are required then DataTable.Clone() can be used. With Clone function only the schema will be copied. But DataTable.Copy() copies both the structure and data

E.g.

DataTable dt = new DataTable();
dt.Columns.Add("Column Name");
dt.Rows.Add("Column Data");
DataTable dt1 = dt.Clone();
DataTable dt2 = dt.Copy();

dt1 will have only the one column but dt2 will have one column with one row.

For getting the first 5 elements of an array, all you need to do is slice the array in question. In Swift, you do it like this: array[0..<5].

To make picking the N first elements of an array a bit more functional and generalizable, you could create an extension method for doing it. For instance:

extension Array {
    func takeElements(var elementCount: Int) -> Array {
        if (elementCount > count) {
            elementCount = count
        }
        return Array(self[0..<elementCount])
    }
}

Write below code in script and also add jQuery library

var getElement = document.getElementById('myID');

if (document.activeElement === getElement) {
        $(document).keydown(function(event) {
            if (event.which === 40) {
                console.log('keydown pressed')
            }
        });
    }

Thank you...

This is my version of the extension methods posted here and in similar questions. This validates the ticks value in an easy to read way and preserves the DateTimeKind of the original DateTime instance. (This has subtle but relevant side effects when storing to a database like MongoDB.)

If the true goal is to truncate a DateTime to a specified value (i.e. Hours/Minutes/Seconds/MS) I recommend implementing this extension method in your code instead. It ensures that you can only truncate to a valid precision and it preserves the important DateTimeKind metadata of your original instance:

public static DateTime Truncate(this DateTime dateTime, long ticks)
{
    bool isValid = ticks == TimeSpan.TicksPerDay 
        || ticks == TimeSpan.TicksPerHour 
        || ticks == TimeSpan.TicksPerMinute 
        || ticks == TimeSpan.TicksPerSecond 
        || ticks == TimeSpan.TicksPerMillisecond;

    // https://stackoverflow.com/questions/21704604/have-datetime-now-return-to-the-nearest-second
    return isValid 
        ? DateTime.SpecifyKind(
            new DateTime(
                dateTime.Ticks - (dateTime.Ticks % ticks)
            ),
            dateTime.Kind
        )
        : throw new ArgumentException("Invalid ticks value given. Only TimeSpan tick values are allowed.");
}

Then you can use the method like this:

DateTime dateTime = DateTime.UtcNow.Truncate(TimeSpan.TicksPerMillisecond);

dateTime.Kind => DateTimeKind.Utc

#!/bin/sh or #!/bin/bash has to be first line of the script because if you don't use it on the first line then the system will treat all the commands in that script as different commands. If the first line is #!/bin/sh then it will consider all commands as a one script and it will show the that this file is running in ps command and not the commands inside the file.

I had this same problem in a large Excel 2000 spreadsheet with hundreds of lines of code. My solution was to make the Worksheet active at the beginning of the Class. I.E. ThisWorkbook.Worksheets("WorkSheetName").Activate This was finally discovered when I noticed that if "WorkSheetName" was active when starting the operation (the code) the error didn't occur. Drove me crazy for quite awhile.

If you would like to modify file names in an editor (such as vim), the click library comes with the command click.edit(), which can be used to receive user input from an editor. Here is an example of how it can be used to refactor files in a directory.

import click
from pathlib import Path

# current directory
direc_to_refactor = Path(".")

# list of old file paths
old_paths = list(direc_to_refactor.iterdir())

# list of old file names
old_names = [str(p.name) for p in old_paths]

# modify old file names in an editor,
# and store them in a list of new file names
new_names = click.edit("\n".join(old_names)).split("\n")

# refactor the old file names
for i in range(len(old_paths)):
    old_paths[i].replace(direc_to_refactor / new_names[i])

I wrote a command line application that uses the same technique, but that reduces the volatility of this script, and comes with more options, such as recursive refactoring. Here is the link to the github page. This is useful if you like command line applications, and are interested in making some quick edits to file names. (My application is similar to the "bulkrename" command found in ranger).

I know it's a really old question, but it's the first result on duckduckgo, so I wanted to share what I think it's a better and more modern solution.

You can use background-blend-mode property to achieve a greyscale image:

#something {
  background-color: #fff;
  background-image: url("yourimage");
  background-blend-mode: luminosity;
}

If you want to remove the effect, just change the blend-mode to initial.

You may need to play a little bit with the background-color if this element is over something with a background. What I've found is that the greyscale does not depend on the actual color but on the alpha value. So, if you have a blue background on the parent, set the same background on #something.

You can also use two images, one with color and the other without and set both as background and play with other blend modes.

https://www.w3schools.com/cssref/pr_background-blend-mode.asp

It won't work on Edge though.

EDIT: I've miss the "fade" part of the question.

If you wan't to make it fade from/to grayscale, you can use a css transition on the background color changeing it's alpha value:

#something {
  background-color: rgba(255,255,255,1);
  background-image: url("yourimage");
  background-blend-mode: luminosity;
  transition: background-color 1s ease-out;
}
#something:hover {
  background-color: rgba(255,255,255,0);
}

I'm also adding a codepen example for completeness https://codepen.io/anon/pen/OBKKVZ

Here's an example of using prepend to add a paragraph to the document.

var element = document.createElement("p");
var text = document.createTextNode("Example text");
element.appendChild(text);
document.body.prepend(element);

result:

<p>Example text</p>

I use them to break up complex queries, especially complex joins and sub-queries. I find I'm using them more and more as 'pseudo-views' to help me get my head around the intent of the query.

My only complaint about them is they cannot be re-used. For example, I may have a stored proc with two update statements that could use the same CTE. But the 'scope' of the CTE is the first query only.

Trouble is, 'simple examples' probably don't really need CTE's!

Still, very handy.

You can use std::find to get an iterator to a value:

#include <algorithm>
std::vector<int>::iterator position = std::find(myVector.begin(), myVector.end(), 8);
if (position != myVector.end()) // == myVector.end() means the element was not found
    myVector.erase(position);

From a sqlite prompt:

sqlite> .read db.sql

Or:

cat db.sql | sqlite3 database.db

Also, your SQL is invalid - you need ; on the end of your statements:

create table server(name varchar(50),ipaddress varchar(15),id init);
create table client(name varchar(50),ipaddress varchar(15),id init);

Big warning on several of the solutions (and your own test) :

When you do : anything | xargs something

xargs will try to fit "as many arguments as possible" after "something", but then you may end up with multiple invocations of "something".

So your attempt: find ... | xargs tar czvf file.tgz may end up overwriting "file.tgz" at each invocation of "tar" by xargs, and you end up with only the last invocation! (the chosen solution uses a GNU -T special parameter to avoid the problem, but not everyone has that GNU tar available)

You could do instead:

find . -type f -print0 | xargs -0 tar -rvf backup.tar
gzip backup.tar

Proof of the problem on cygwin:

$ mkdir test
$ cd test
$ seq 1 10000 | sed -e "s/^/long_filename_/" | xargs touch 
    # create the files
$ seq 1 10000 | sed -e "s/^/long_filename_/" | xargs tar czvf archive.tgz
    # will invoke tar several time as it can'f fit 10000 long filenames into 1
$ tar tzvf archive.tgz | wc -l
60
    # in my own machine, I end up with only the 60 last filenames, 
    # as the last invocation of tar by xargs overwrote the previous one(s)

# proper way to invoke tar: with -r  (which append to an existing tar file, whereas c would overwrite it)
# caveat: you can't have it compressed (you can't add to a compressed archive)
$ seq 1 10000 | sed -e "s/^/long_filename_/" | xargs tar rvf archive.tar #-r, and without z
$ gzip archive.tar
$ tar tzvf archive.tar.gz | wc -l
10000 
  # we have all our files, despite xargs making several invocations of the tar command

 

Note: that behavior of xargs is a well know diccifulty, and it is also why, when someone wants to do :

find .... | xargs grep "regex"

they intead have to write it:

find ..... | xargs grep "regex" /dev/null

That way, even if the last invocation of grep by xargs appends only 1 filename, grep sees at least 2 filenames (as each time it has: /dev/null, where it won't find anything, and the filename(s) appended by xargs after it) and thus will always display the file names when something maches "regex". Otherwise you may end up with the last results showing matches without a filename in front.

You can use ngModel like

<input type="checkbox" [ngModel]="checkboxValue" (ngModelChange)="addProp($event)" data-md-icheck/>

To update the checkbox state by updating the property checkboxValue in your code and when the checkbox is changed by the user addProp() is called.

$output = preg_replace('/\s+/', ' ',$input);

\s is shorthand for [ \t\n\r]. Multiple spaces will be replaced with single space.

If you can't use "viewWillDisappear" or similar method, try to subclass UINavigationController. This is the header class:

#import <Foundation/Foundation.h>
@class MyViewController;

@interface CCNavigationController : UINavigationController

@property (nonatomic, strong) MyViewController *viewController;

@end

Implementation class:

#import "CCNavigationController.h"
#import "MyViewController.h"

@implementation CCNavigationController {

}
- (UIViewController *)popViewControllerAnimated:(BOOL)animated {
    @"This is the moment for you to do whatever you want"
    [self.viewController doCustomMethod];
    return [super popViewControllerAnimated:animated];
}

@end

In the other hand, you need to link this viewController to your custom NavigationController, so, in your viewDidLoad method for your regular viewController do this:

@implementation MyViewController {
    - (void)viewDidLoad
    {
        [super viewDidLoad];
        ((CCNavigationController*)self.navigationController).viewController = self;
    }
}

In A1 of your new sheet, put this:

=OFFSET(Sheet1!$A$1,(ROW()-1)*7,0)

... and copy down. If you start somewhere other than row 1, change ROW() to ROW(A1) or some other cell on row 1, then copy down again.

If you want to copy the nth line but multiple columns, use the formula:

=OFFSET(Sheet1!A$1,(ROW()-1)*7,0)

This can be copied right too.

Use an call thru section, it works

<div id="content">
     <section id="home">
               ...
     </section>

Call the above the thru

 <a href="#home">page1</a>

Scrolling needs jquery paste this.. on above to ending body closing tag..

<script>
  $(function() {
      $('a[href*=#]:not([href=#])').click(function() {
          if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname) {
              var target = $(this.hash);
              target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
              if (target.length) {
                  $('html,body').animate({
                      scrollTop: target.offset().top
                  }, 1000);
                  return false;
              }
          }
      });
  });
</script>

SELECT  name
FROM    orders,company
WHERE   orderID = 1
        AND companyID IN (attachedCompanyIDs)

attachedCompanyIDs is a scalar value which is cast into INT (type of companyID).

The cast only returns numbers up to the first non-digit (a comma in your case).

Thus,

companyID IN ('1,2,3') = companyID IN (CAST('1,2,3' AS INT)) = companyID IN (1)

In PostgreSQL, you could cast the string into array (or store it as an array in the first place):

SELECT  name
FROM    orders
JOIN    company
ON      companyID = ANY (('{' | attachedCompanyIDs | '}')::INT[])
WHERE   orderID = 1

and this would even use an index on companyID.

Unfortunately, this does not work in MySQL since the latter does not support arrays.

You may find this article interesting (see #2):

• 10 things in MySQL (that won’t work as expected)

Update:

If there is some reasonable limit on the number of values in the comma separated lists (say, no more than 5), so you can try to use this query:

SELECT  name
FROM    orders
CROSS JOIN
        (
        SELECT  1 AS pos
        UNION ALL
        SELECT  2 AS pos
        UNION ALL
        SELECT  3 AS pos
        UNION ALL
        SELECT  4 AS pos
        UNION ALL
        SELECT  5 AS pos
        ) q
JOIN    company
ON      companyID = CAST(NULLIF(SUBSTRING_INDEX(attachedCompanyIDs, ',', -pos), SUBSTRING_INDEX(attachedCompanyIDs, ',', 1 - pos)) AS UNSIGNED)

I finally found out how to do this! Basically you need to run adb shell first and then while you're in the shell run su, which will switch the shell to run as root!

$: adb shell
$: su

The one problem I still have is that sqlite3 is not installed so the command is not recognized.

To animate your 3D object, use the code:

<script>

$(document).ready(function(){

    var x = 100;
    var y = 0;
setInterval(function(){
    x += 1;
    y += 1;
    var element = document.getElementById('cube');
    element.style.webkitTransform = "translateZ(-100px) rotateY("+x+"deg) rotateX("+y+"deg)"; //for safari and chrome
    element.style.MozTransform = "translateZ(-100px) rotateY("+x+"deg) rotateX("+y+"deg)"; //for firefox
},50);
//for other browsers use:   "msTransform",    "OTransform",    "transform"

});

</script>

So after research the following is discovered:

For a div#bar setting display:block; width: auto; causes the equivalent of outerWidth:100%;

For a table#bar you need to wrap it in a div with the rules stated below. So your structure becomes:

<div id="foo">
 <div id="barWrap" style="border....">
  <table id="bar" style="width: 100%; border: 0; padding: 0; margin: 0;">

This way the table takes up the parent div 100%, and #barWrap is used to add borders/margin/padding to the #bar table. Note that you will need to set the background of the whole thing in #barWrap and have #bar's background be transparent or the same as #barWrap.

For textarea#bar and input#bar you need to do the same thing as table#bar, the down side is that by removing the borders you stop native widget rendering of the input/textarea and the #barWrap's borders will look a bit different than everything else, so you will probably have to style all your inputs this way.

As of pandas v0.14.1, you can utilize select_dtypes() to select columns by dtype

In [2]: df = pd.DataFrame({'NAME': list('abcdef'),
    'On_Time': [True, False] * 3,
    'On_Budget': [False, True] * 3})

In [3]: df.select_dtypes(include=['bool'])
Out[3]:
  On_Budget On_Time
0     False    True
1      True   False
2     False    True
3      True   False
4     False    True
5      True   False

In [4]: mylist = list(df.select_dtypes(include=['bool']).columns)

In [5]: mylist
Out[5]: ['On_Budget', 'On_Time']

Just declare it outside class definition.

If your namespace's name is X, you will be able to access the enum's values by X.card_suit

This will trim off any combination of carriage returns and newlines from the end of s:

s = s.TrimEnd(new char[] { '\r', '\n' });

Edit: Or as JP kindly points out, you can spell that more succinctly as:

s = s.TrimEnd('\r', '\n');

Not sure why it is in the module shutil, but it landed there in Python 3.3, Querying the size of the output terminal:

>>> import shutil
>>> shutil.get_terminal_size((80, 20))  # pass fallback
os.terminal_size(columns=87, lines=23)  # returns a named-tuple

A low-level implementation is in the os module. Also works in Windows.

A backport is now available for Python 3.2 and below:

• https://pypi.python.org/pypi/backports.shutil_get_terminal_size

this one is out of left field but its a nice little map for resizing your current split to 80 characters if you've got the line numbers on:

" make window 80 + some for numbers wide  
noremap <Leader>w :let @w=float2nr(log10(line("$")))+82\|:vertical resize <c-r>w<cr> 

Do this:

$vi .vimrc

And add this line:

autocmd FileType cpp setlocal expandtab shiftwidth=4 softtabstop=4 cindent

This is only for a cpp file. You can do this for another file type, also just by modifying the filetype...

I was looking for a cross-browser text-stroke solution that works when overlaid on background images. think I have a solution for this that doesn't involve extra mark-up, js and works in IE7-9 (I haven't tested 6), and doesn't cause aliasing problems.

This is a combination of using CSS3 text-shadow, which has good support except IE (http://caniuse.com/#search=text-shadow), then using a combination of filters for IE. CSS3 text-stroke support is poor at the moment.

IE Filters

The glow filter (http://www.impressivewebs.com/css3-text-shadow-ie/) looks terrible, so I didn't use that.

David Hewitt's answer involved adding dropshadow filters in a combination of directions. ClearType is then removed unfortunately so we end up with badly aliased text.

I then combined some of the elements suggested on useragentman with the dropshadow filters.

Putting it together

This example would be black text with a white stroke. I'm using conditional html classes by the way to target IE (http://paulirish.com/2008/conditional-stylesheets-vs-css-hacks-answer-neither/).

#myelement {
    color: #000000;
    text-shadow:
    -1px -1px 0 #ffffff,  
    1px -1px 0 #ffffff,
    -1px 1px 0 #ffffff,
    1px 1px 0 #ffffff;
}

html.ie7 #myelement,
html.ie8 #myelement,
html.ie9 #myelement {
    background-color: white;
    filter: progid:DXImageTransform.Microsoft.Chroma(color='white') progid:DXImageTransform.Microsoft.Alpha(opacity=100) progid:DXImageTransform.Microsoft.dropshadow(color=#ffffff,offX=1,offY=1) progid:DXImageTransform.Microsoft.dropshadow(color=#ffffff,offX=-1,offY=1) progid:DXImageTransform.Microsoft.dropshadow(color=#ffffff,offX=1,offY=-1) progid:DXImageTransform.Microsoft.dropshadow(color=#ffffff,offX=-1,offY=-1);
    zoom: 1;

You should follow the guidelines on Add a secondary horizontal axis:

Add a secondary horizontal axis

To complete this procedure, you must have a chart that displays a secondary vertical axis. To add a secondary vertical axis, see Add a secondary vertical axis.

1. Click a chart that displays a secondary vertical axis. This displays the Chart Tools, adding the Design, Layout, and Format tabs.

2. On the Layout tab, in the Axes group, click Axes.

   

3. Click Secondary Horizontal Axis, and then click the display option that you want.

Add a secondary vertical axis

You can plot data on a secondary vertical axis one data series at a time. To plot more than one data series on the secondary vertical axis, repeat this procedure for each data series that you want to display on the secondary vertical axis.

1. In a chart, click the data series that you want to plot on a secondary vertical axis, or do the following to select the data series from a list of chart elements:

   • Click the chart.

     This displays the Chart Tools, adding the Design, Layout, and Format tabs.

   • On the Format tab, in the Current Selection group, click the arrow in the Chart Elements box, and then click the data series that you want to plot along a secondary vertical axis.

     

2. On the Format tab, in the Current Selection group, click Format Selection. The Format Data Series dialog box is displayed.

   Note: If a different dialog box is displayed, repeat step 1 and make sure that you select a data series in the chart.

3. On the Series Options tab, under Plot Series On, click Secondary Axis and then click Close.

   A secondary vertical axis is displayed in the chart.

4. To change the display of the secondary vertical axis, do the following:

   • On the Layout tab, in the Axes group, click Axes.

   • Click Secondary Vertical Axis, and then click the display option that you want.

5. To change the axis options of the secondary vertical axis, do the following:

   • Right-click the secondary vertical axis, and then click Format Axis.

   • Under Axis Options, select the options that you want to use.

Try this:

#include <stdio.h>
int main()
{
    char s[] = "fffffffe";
    int x;
    sscanf(s, "%x", &x);
    printf("%u\n", x);
}

Something like:

find /path/ -type f -exec stat \{} --printf="%y\n" \; | 
     sort -n -r | 
     head -n 1

Explanation:

• the find command will print modification time for every file recursively ignoring directories (according to the comment by IQAndreas you can't rely on the folders timestamps)
• sort -n (numerically) -r (reverse)
• head -n 1: get the first entry

Remember when you used to sum, for example 2 & 3, in your old calculator and every time you hit the = you see 3 added to the total, the += does similar job. Example:

>>> orange = 2
>>> orange += 3
>>> print(orange)
5
>>> orange +=3
>>> print(orange)
8

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

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

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

Unless your compiler is different than the one supplied with the Mac XCode Dev tools, just follow the instructions in section 5.1 of Getting Started Guide for Unix Variants. The configuration and building of the latest source couldn't be easier, and it took all about about 1 minute to configure and 10 minutes to compile.

Here's a way to do it:

>>> mylist = ['a', 'b', 'c', 'd']
>>> [item for item in enumerate(mylist)]
[(0, 'a'), (1, 'b'), (2, 'c'), (3, 'd')]

Alternatively, you can do:

>>> [(i, j) for i, j in enumerate(mylist)]
[(0, 'a'), (1, 'b'), (2, 'c'), (3, 'd')]

The reason you got an error was that you were missing the () around i and j to make it a tuple.

or

$('element').text('TEXT TO INSERT');

1- There is no way to actually destroy an object in javascript, but using delete, we could remove a reference from an object:

var obj = {};
obj.mypointer = null;
delete obj.mypointer;

2- The important point about the delete keyword is that it does not actually destroy the object BUT if only after deleting that reference to the object, there is no other reference left in the memory pointed to the same object, that object would be marked as collectible. The delete keyword deletes the reference but doesn't GC the actual object. it means if you have several references of the same object, the object will be collected just after you delete all the pointed references.

3- there are also some tricks and workarounds that could help us out, when we want to make sure we do not leave any memory leaks behind. for instance if you have an array consisting several objects, without any other pointed reference to those objects, if you recreate the array all those objects would be killed. For instance if you have var array = [{}, {}] overriding the value of the array like array = [] would remove the references to the two objects inside the array and those two objects would be marked as collectible.

4- for your solution the easiest way is just this:

var storage = {};
storage.instance = new Class();
//since 'storage.instance' is your only reference to the object, whenever you wanted to destroy do this:
storage.instance = null;
// OR
delete storage.instance;

As mentioned above, either setting storage.instance = null or delete storage.instance would suffice to remove the reference to the object and allow it to be cleaned up by the GC. The difference is that if you set it to null then the storage object still has a property called instance (with the value null). If you delete storage.instance then the storage object no longer has a property named instance.

and WHAT ABOUT destroy method ??

the paradoxical point here is if you use instance.destroy in the destroy function you have no access to the actual instance pointer, and it won't let you delete it.

The only way is to pass the reference to the destroy function and then delete it:

// Class constructor
var Class = function () {
     this.destroy = function (baseObject, refName) {
         delete baseObject[refName];
     };
};

// instanciate
var storage = {};
storage.instance = new Class();
storage.instance.destroy(object, "instance");
console.log(storage.instance); // now it is undefined

BUT if I were you I would simply stick to the first solution and delete the object like this:

storage.instance = null;
// OR
delete storage.instance;

WOW it was too much :)

public class SwapElements {

public static void main(String[] args) {

    int[] arr1 = new int[5];

}

The function has to be declared before it's getting called. This could be done in various ways:

• Write down the prototype in a header
  Use this if the function shall be callable from several source files. Just write your prototype
  int Fibonacci(int number);
  down in a .h file (e.g. myfunctions.h) and then #include "myfunctions.h" in the C code.

• Move the function before it's getting called the first time
  This means, write down the function
  int Fibonacci(int number){..}
  before your main() function

• Explicitly declare the function before it's getting called the first time
  This is the combination of the above flavors: type the prototype of the function in the C file before your main() function

As an additional note: if the function int Fibonacci(int number) shall only be used in the file where it's implemented, it shall be declared static, so that it's only visible in that translation unit.

The underlying data type of a datetime in Excel is a 64-bit floating point number where the length of a day equals 1 and 1st Jan 1900 00:00 equals 1. So 11th June 2009 17:30 is about 39975.72917.

If a cell contains a numeric value such as this, it can be converted to a datetime simply by applying a datetime format to the cell.

So, if you can convert your datetimes to numbers using the above formula, output them to the relevant cells and then set the cell formats to the appropriate datetime format, e.g. yyyy-mm-dd hh:mm:ss, then it should be possible to achieve what you want.

Also Stefan de Bruijn has pointed out that there is a bug in Excel in that it incorrectly assumes 1900 is a leap year so you need to take that into account when making your calculations (Wikipedia).

if any(word in 'some one long two phrase three' for word in list_):

Make left-margin: 2em or so will push the whole text including first line to right 2em. Than add text-indent (applicable to first line) as -2em or so.. This brings first line back to start without margin. I tried it for list tags

<style>
    ul li{
      margin-left: 2em;
      text-indent: -2em;
    }
</style>

The 'wrapper' task in gradle is called if gradlew command is used, if you use gradle command to build the wrapper task is not called. So, there are two ways you can change your gradle version.

1. Use 'gradlew build' command, this command will call the wrapper task that you mentioned. That task will change the 'distributionUrl' parameter in gradle-wrapper.properties file and it will automatically download the gradle version you want. Example distributionUrl in the file for version 4.2. distributionUrl=https://services.gradle.org/distributions/gradle-4.2-bin.zip

2. If you are not using gradle wrapper simply download the version of the gradle you want and set environment variable path and also show it to IDEA.

P.S. for more information about gradle wrapper I suggest you to read: https://docs.gradle.org/current/userguide/gradle_wrapper.html

Frames have been deprecated because they caused trouble for url navigation and hyperlinking, because the url would just take to you the index page (with the frameset) and there was no way to specify what was in each of the frame windows. Today, webpages are often generated by server-side technologies such as PHP, ASP.NET, Ruby etc. So instead of using frames, pages can simply be generated by merging a template with content like this:

Template File

<html>
<head>
<title>{insert script variable for title}</title>
</head>

<body>
  <div class="menu">
   {menu items inserted here by server-side scripting}
  </div>
  <div class="main-content">
   {main content inserted here by server-side scripting}
  </div>
</body>
</html>

If you don't have full support for a server-side scripting language, you could also use server-side includes (SSI). This will allow you to do the same thing--i.e. generate a single web page from multiple source documents.

But if you really just want to have a section of your webpage be a separate "window" into which you can load other webpages that are not necessarily located on your own server, you will have to use an iframe.

You could emulate your example like this:

Frames Example

<html>
<head>
  <title>Frames Test</title>
  <style>
   .menu {
      float:left;
      width:20%;
      height:80%;
    }
    .mainContent {
      float:left;
      width:75%;
      height:80%;
    }
  </style>
</head>
<body>
  <iframe class="menu" src="menu.html"></iframe>
  <iframe class="mainContent" src="events.html"></iframe>
</body>
</html>

There are probably better ways to achieve the layout. I've used the CSS float attribute, but you could use tables or other methods as well.

You can use android:weightSum="2" on the parent layout combined with android:layout_height="1" on the child layout.

           <LinearLayout
                android:layout_height="match_parent"
                android:layout_width="wrap_content"
                android:weightSum="2"
                >

                <ImageView
                    android:layout_height="1"
                    android:layout_width="wrap_content" />

            </LinearLayout>

Simple solution:

<iframe onload="this.style.height=this.contentWindow.document.body.scrollHeight + 'px';" ...></iframe>

This works when the iframe and parent window are in the same domain. It does not work when the two are in different domains.

Root Cause #1 - The Delimiter Problem

Sql injection is possible because we use quotation marks to delimit strings and also to be parts of strings, making it impossible to interpret them sometimes. If we had delimiters that could not be used in string data, sql injection never would have happened. Solving the delimiter problem eliminates the sql injection problem. Structure queries do that.

Root Cause #2 - Human Nature, People are Crafty and Some Crafty People Are Malicious And All People Make Mistakes

The other root cause of sql injection is human nature. People, including programmers, make mistakes. When you make a mistake on a structured query, it does not make your system vulnerable to sql injection. If you are not using structured queries, mistakes can generate sql injection vulnerability.

How Structured Queries Resolve the Root Causes of SQL Injection

Structured Queries Solve The Delimiter Problem, by by putting sql commands in one statement and putting the data in a separate programming statement. Programming statements create the separation needed.

Structured queries help prevent human error from creating critical security holes. With regard to humans making mistakes, sql injection cannot happen when structure queries are used. There are ways of preventing sql injection that don't involve structured queries, but normal human error in that approaches usually leads to at least some exposure to sql injection. Structured Queries are fail safe from sql injection. You can make all the mistakes in the world, almost, with structured queries, same as any other programming, but none that you can make can be turned into a ssstem taken over by sql injection. That is why people like to say this is the right way to prevent sql injection.

So, there you have it, the causes of sql injection and the nature structured queries that makes them impossible when they are used.

Just type this command in your command line:

python manage.py changepassword yourusername

Yes, Javascript always passes by value, but in an array or object, the value is a reference to it, so you can 'change' the contents.

But, I think you already read it on SO; here you have the documentation you want:

To be able to use a lib project you need to include it in your application's settings.gradle add:

include '..:ExpandableButtonMenu:library'

and then in your build.gradle add:

compile project(':..:ExpandableButtonMenu:library') 

place ExpandableButtonMenu project along side your own (same folder)

Sending data from Activity to a Fragment

Activity:

Bundle bundle = new Bundle();
String myMessage = "Stackoverflow is cool!";
bundle.putString("message", myMessage );
FragmentClass fragInfo = new FragmentClass();
fragInfo.setArguments(bundle);
transaction.replace(R.id.fragment_single, fragInfo);
transaction.commit();

Fragment:

Reading the value in fragment

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    String myValue = this.getArguments().getString("message");
    ...
    ...
    ...
}

But if you want to send values from Fragment to Activity, read the answer of jpardogo, you must need interfaces, more info: Communicating with other Fragments

@Nicolai is correct about casting and why the condition is false for any data. i guess you prefer the first form because you want to avoid date manipulation on the input string, correct? you don't need to be afraid:

SELECT *
FROM table
WHERE update_date >= '2013-05-03'::date
AND update_date < ('2013-05-03'::date + '1 day'::interval);

You can use:

show full processlist

which will list all the connections in MySQL and the current state of connection as well as the query being executed. There's also a shorter variant show processlist; which displays the truncated query as well as the connection stats.

You could create a simple AutoIt Script that does the job for you, compile it as an executable and perform a system call there.

in au3 Script:

; how to use: MouseClick ( "button" [, x, y [, clicks = 1 [, speed = 10]]] )
MouseClick ( "left" , $CmdLine[1], $CmdLine[1] )

Now find aut2exe in your au3 Folder or find 'Compile Script to .exe' in your Start Menu and create an executable.

in your Java class call:

Runtime.getRuntime().exec(
    new String[]{
        "yourscript.exe", 
        String.valueOf(mypoint.x),
        String.valueOf(mypoint.y)}
);

AutoIt will behave as if it was a human and won't be detected as a machine.

Find AutoIt here: https://www.autoitscript.com/

//R stands for ROW and C stands for COLUMN:

//i stands for ROW and j stands for COLUMN:

#include<stdio.h>

int main(){

    int M[100][100];

    int R,C,i,j;

    printf("Please enter how many rows you want:\n");

    scanf("%d",& R);

    printf("Please enter how column you want:\n");

    scanf("%d",& C);

    printf("Please enter your matrix:\n");

    for(i = 0; i < R; i++){

        for(j = 0; j < C; j++){

            scanf("%d", &M[i][j]);

        }

        printf("\n");

    }
    for(i = 0; i < R; i++){

        for(j = 0; j < C; j++){

            printf("%d\t", M[i][j]);

        }
        printf("\n");

   }

   getch();

   return 0;
}

You can use as following.

$start_date = date('Y-m-d H:i:s');
$end_date = date("Y-m-d 23:59:59", strtotime('+3 days', strtotime($start_date)));

You can also set days as constant and use like below.

if (!defined('ADD_DAYS')) define('ADD_DAYS','+3 days');
$end_date = date("Y-m-d 23:59:59", strtotime(ADD_DAYS, strtotime($start_date)));

In my case, I've git clone a lib which had an interpreter of

#!/usr/bin/env python

While python was leading to Python2.7 even though my main code was running with python3.6 ... it still created a *.pyc file for 2.7 version ...

I can say that this error probably is a result of a mix between 2.7 & 3+ versions, this is why cleanup ( in any way you can think of that you're using ) - will help here ...

• don't forget to adjust those Python2x code -> python 3...

You can simply add the two.

• if the Time part of your Date column is always zero
• and the Date part of your Time column is also always zero (base date: January 1, 1900)

Adding them returns the correct result.

SELECT Combined = MyDate + MyTime FROM MyTable

Rationale (kudos to ErikE/dnolan)

It works like this due to the way the date is stored as two 4-byte Integers with the left 4-bytes being the date and the right 4-bytes being the time. Its like doing $0001 0000 + $0000 0001 = $0001 0001

Edit regarding new SQL Server 2008 types

Date and Time are types introduced in SQL Server 2008. If you insist on adding, you can use Combined = CAST(MyDate AS DATETIME) + CAST(MyTime AS DATETIME)

Edit2 regarding loss of precision in SQL Server 2008 and up (kudos to Martin Smith)

Have a look at How to combine date and time to datetime2 in SQL Server? to prevent loss of precision using SQL Server 2008 and up.

for bootstrap 3 I have the following code in my navbar component

/**
 * Navbar styling.
 */
@mobile:          ~"screen and (max-width: @{screen-xs-max})";
@tablet:          ~"screen and (min-width: @{screen-sm-min})";
@normal:          ~"screen and (min-width: @{screen-md-min})";
@wide:            ~"screen and (min-width: @{screen-lg-min})";
@grid-breakpoint: ~"screen and (min-width: @{grid-float-breakpoint})";

then you can use something like

@media wide { selector: style }

This uses whatever value you have the variables set to.

Escaping allows you to use any arbitrary string as property or variable value. Anything inside ~"anything" or ~'anything' is used as is with no changes except interpolation.

How about:

public static T As<T>(this object obj)
    {
        return JsonConvert.DeserializeObject<T>(JsonConvert.SerializeObject(obj));
    }

I have created a function that allows me to obtain this feature:

function redirect_blank(url) {
  var a = document.createElement('a');
  a.target="_blank";
  a.href=url;
  a.click();
}

What ever attribute is added to the button/anchor/link to disable it, bootstrap is just adding style to it and user will still be able to click it while there is still onclick event. So my simple solution is to check if it is disabled and remove/add onclick event:

if (!('#button').hasAttr('disabled'))
 $('#button').attr('onclick', 'someFunction();');
else
 $('#button').removeattr('onclick');

Right variant for .NET 4.5 +

C# code

public class VersionManager
{
    private static string filterString;

    public static string FilterString
    {
        get => filterString;
        set
        {
            if (filterString == value)
                return;

            filterString = value;

            StaticPropertyChanged?.Invoke(null, FilterStringPropertyEventArgs);
        }
    }

    private static readonly PropertyChangedEventArgs FilterStringPropertyEventArgs = new PropertyChangedEventArgs (nameof(FilterString));
    public static event PropertyChangedEventHandler StaticPropertyChanged;
}

XAML binding (attention to braces they are (), not {})

<TextBox Text="{Binding Path=(yournamespace:VersionManager.FilterString)}" />

You can use backslash either way;

string str = "He said to me, \"Hello World\". How are you?";

It prints;

He said to me, "Hello World". How are you?

which is exactly same prints with;

string str = @"He said to me, ""Hello World"". How are you?";

Here is a DEMO.

" is still part of your string.

Great answer above. Another way is to use the great yaml jq wrapper tool, yq at https://github.com/kislyuk/yq

Please follow these steps

1. In User Variables

   Set VARIABLE NAME=ANT_HOME VARIABLE PATH =C:\Program Files\apache-ant-1.9.7

2.Edit User Variable PATH = %ANT_HOME%\bin

3. Go to System Variables

   • Set Path =%ANT_HOME%\bin

All of this can easily be acheived in the xaml by adding the following code in the grid

<Grid>
    <Grid.Background>  
        <ImageBrush ImageSource="/MyProject;component/Images/bg.png"/>     
    </Grid.Background>
</Grid>

Left for you to do, is adding a folder to the solution called 'Images' and adding an existing file to your new 'Images' folder, in this case called 'bg.png'

Maybe you could try:

findIndex was added in 1.8:

index = _.findIndex(tv, function(voteItem) { return voteItem.id == voteID })

See: http://underscorejs.org/#findIndex

Alternatively, this also works, if you don't mind making another temporary list:

index = _.indexOf(_.pluck(tv, 'id'), voteId);

See: http://underscorejs.org/#pluck

Please use the script above script for ajax upload. It will work

string str = Console.ReadLine(); //Reads a character from console
double a = double.Parse(str); //Converts str into the type double
double b = a * Math.PI; // Multiplies by PI
Console.WriteLine("{0}", b); // Writes the number to console

Console.Read() reads a string from console A SINGLE CHARACTER AT A TIME (but waits for an enter before going on. You normally use it in a while cycle). So if you write 25 + Enter, it will return the unicode value of 2 that is 50. If you redo a second Console.Read() it will return immediately with 53 (the unicode value of 5). A third and a fourth Console.Read() will return the end of line/carriage characters. A fifth will wait for new input.

Console.ReadLine() reads a string (so then you need to change the string to a double)

Faced the same problem as OP:

• Tomcat returned response when accessing directly via SOAP UI
• Didn't load html files
• When used Apache properties mentioned by the previous answer, web-page appeared but AngularJS couldn't get HTTP response

Tomcat SSL certificate was expired while a browser showed it as secure - Apache certificate was far from expiration. Updating Tomcat KeyStore file solved the problem.

I have written an implementation that properly works with dates exactly one year apart.

However, it does not gracefully handle negative timespans, unlike the other algorithm. It also doesn't use its own date arithmetic, instead relying upon the standard library for that.

So without further ado, here is the code:

DateTime zeroTime = new DateTime(1, 1, 1);

DateTime a = new DateTime(2007, 1, 1);
DateTime b = new DateTime(2008, 1, 1);

TimeSpan span = b - a;
// Because we start at year 1 for the Gregorian
// calendar, we must subtract a year here.
int years = (zeroTime + span).Year - 1;

// 1, where my other algorithm resulted in 0.
Console.WriteLine("Yrs elapsed: " + years);

It comes from +[UIWindow _synchronizeDrawingAcrossProcessesOverPort:withPreCommitHandler:] via os_log API. It doesn't depend from another components/frameworks that you are using(only from UIKit) - it reproduces in clean single view application project on changing interface orientation.

This method consists from 2 parts:

1. adding passed precommit handler to list of handlers;
2. do some work, that depends on current finite state machine state.

When second part fails (looks like prohibited transition), it prints message above to error log. However, I think that this problem is not fatal: there are 2 additional assert cases in this method, that will lead to crash in debug.

Seems that radar is the best we can do.

ResponseEntity is meant to represent the entire HTTP response. You can control anything that goes into it: status code, headers, and body.

@ResponseBody is a marker for the HTTP response body and @ResponseStatus declares the status code of the HTTP response.

@ResponseStatus isn't very flexible. It marks the entire method so you have to be sure that your handler method will always behave the same way. And you still can't set the headers. You'd need the HttpServletResponse or a HttpHeaders parameter.

Basically, ResponseEntity lets you do more.

The compiler cannot guess what should be passed for the base constructor argument. You have to do it explicitly:

public class child : parent {
    public child(int i) : base(i) {
        Console.WriteLine("child");
    }
}

They have totally different meaning and aren't really related at all.

ORDER BY allows you to sort the result set according to different criteria, such as first sort by name from a-z, then sort by the price highest to lowest.

(ORDER BY name, price DESC)

GROUP BY allows you to take your result set, group it into logical groups and then run aggregate queries on those groups. You could for instance select all employees, group them by their workplace location and calculate the average salary of all employees of each workplace location.

forever might be of interest to you. It will run your .js-File 24/7 with logging options. Here are two snippets from the help text:

[Long Running Process] The forever process will continue to run outputting log messages to the console. ex. forever -o out.log -e err.log my-script.js

and

[Daemon] The forever process will run as a daemon which will make the target process start in the background. This is extremely useful for remote starting simple node.js scripts without using nohup. It is recommended to run start with -o -l, & -e. ex. forever start -l forever.log -o out.log -e err.log my-daemon.js forever stop my-daemon.js

The question is adding various different objects into one.

let obj = {};
const obj1 = { foo: 'bar' };
const obj2 = { bar: 'foo' };
Object.assign(obj, obj1, obj2);
//output => {foo: 'bar', bar: 'foo'};

lets say you have one object with multiple keys that are objects:

let obj = {
  foo: { bar: 'foo' },
  bar: { foo: 'bar' }
}

this was the solution I found (still have to foreach :/)

let objAll = {};

Object.values(obj).forEach(o => {
  objAll = {...objAll, ...o};
});

By doing this we can dynamically add ALL object keys into one.

// Output => { bar: 'foo', foo: 'bar' }

Well, its not compulsory to restart the emulator you can also reset adb from eclipse itself.

1.) Go to DDMS and there is a reset adb option, please see the image below.

2.) You can restart adb manually from command prompt

  run->cmd->your_android_sdk_path->platform-tools>

Then write the below commands.

adb kill-server - To kill the server forcefully

adb start-server - To start the server

UPDATED:

F:\android-sdk-windows latest\platform-tools>adb kill-server

F:\android-sdk-windows latest\platform-tools>adb start-server
* daemon not running. starting it now on port 5037 *
* daemon started successfully *

You could come across another problem. After installing Boost on the Linux Mint I've had the same problem. Linking -lboost_system or -lboost_system-mt haven't worked because library have had name libboost_system.so.1.54.0.

So the solution is to create symbolic link to the original file. In my case

sudo ln -s /usr/lib/x86_64-linux-gnu/libboost_system.so.1.54.0 /usr/lib/libboost_system.so

For more information see this question.

You can easily write the method to do that :

  public static String toCamelCase(final String init) {
    if (init == null)
        return null;

    final StringBuilder ret = new StringBuilder(init.length());

    for (final String word : init.split(" ")) {
        if (!word.isEmpty()) {
            ret.append(Character.toUpperCase(word.charAt(0)));
            ret.append(word.substring(1).toLowerCase());
        }
        if (!(ret.length() == init.length()))
            ret.append(" ");
    }

    return ret.toString();
}

time after 30 min, this easiest solution in php

date('Y-m-d H:i:s', strtotime("+30 minutes"));

for DateTime class (PHP 5 >= 5.2.0, PHP 7)

$dateobj = new DateTime();
$dateobj ->modify("+30 minutes"); 

You should use DateTime.TryParseExcact if you know the format, or if not and want to use the system settings DateTime.TryParse. And to print the date,DateTime.ToString with the right format in the argument. To get the year, month or day you have DateTime.Year, DateTime.Month or DateTime.Day.

See DateTime Structures in MSDN for additional references.

An important point that the other answers forgot, is that "@keyword" is compiled into "keyword" in the CIL.

So if you have a framework that was made in, say, F#, which requires you to define a class with a property named "class", you can actually do it.

It is not that useful in practice, but not having it would prevent C# from some forms of language interop.

I usually see it used not for interop, but to avoid the keyword restrictions (usually on local variable names, where this is the only effect) ie.

private void Foo(){
   int @this = 2;
}

but I would strongly discourage that! Just find another name, even if the 'best' name for the variable is one of the reserved names.

Wrap all the children inside of another LinearLayout with wrap_content for both the width and the height as well as the vertical orientation.

I had same error. It occurred when s3 client was created with different endpoint than the one which was set up while creating bucket.

• ERROR CODE - The bucket was set up with EAST Region.

s3Client = New AmazonS3Client(AWS_ACCESS_KEY, AWS_SECRET_KEY, RegionEndpoint.USWest2)

• FIX

s3Client = New AmazonS3Client(AWS_ACCESS_KEY, AWS_SECRET_KEY, RegionEndpoint.USEast1)

General purpose normalisation function to format any timestamp from any timezone to other. Very useful for storing datetimestamps of users from different timezones in a relational database. For database comparisons store timestamp as UTC and use with gmdate('Y-m-d H:i:s')

/**
 * Convert Datetime from any given olsonzone to other.
 * @return datetime in user specified format
 */

function datetimeconv($datetime, $from, $to)
{
    try {
        if ($from['localeFormat'] != 'Y-m-d H:i:s') {
            $datetime = DateTime::createFromFormat($from['localeFormat'], $datetime)->format('Y-m-d H:i:s');
        }
        $datetime = new DateTime($datetime, new DateTimeZone($from['olsonZone']));
        $datetime->setTimeZone(new DateTimeZone($to['olsonZone']));
        return $datetime->format($to['localeFormat']);
    } catch (\Exception $e) {
        return null;
    }
}

Usage:

$from = ['localeFormat' => "d/m/Y H:i A", 'olsonZone' => 'Asia/Calcutta'];

$to = ['localeFormat' => "Y-m-d H:i:s", 'olsonZone' => 'UTC'];

datetimeconv("14/05/1986 10:45 PM", $from, $to); // returns "1986-05-14 17:15:00"

I think you may have the wrong Git repository URL.

Open .git/config and find the [remote "origin"] section. Make sure you're using the SSH one:

ssh://[email protected]/username/repo.git

You can see the SSH URL in the main page of your repository if you click Clone or download and choose ssh.

And NOT the https or git one:

https://github.com/username/repo.git
git://github.com/username/repo.git

You can now validate with just the SSH key instead of the username and password.

If Git complains that 'origin' has already been added, open the .config file and edit the url = "..." part after [remote origin] as url = ssh://github/username/repo.git

The same goes for other services. Make sure the address looks like: protocol://something@url

E.g. .git/config for Azure DevOps:

[remote "origin"]
    url = https://[email protected]/mystore/myproject/
    fetch = +refs/heads/*:refs/remotes/origin/*

If you have couple of json files:

import data from 'sample.json';

If you were to dynamically load one of the many json file, you might have to use a fetch instead:

fetch(`${fileName}.json`)
  .then(response => response.json())
  .then(data => console.log(data))

You may drag'n'drop your folder to Side bar. To enable Side bar you should do View -> Side bar -> show opened files. You'll got opened files (tabs) tree and folder structure at Side bar.

Running python -h, I see a command line option:

-u : unbuffered binary stdout and stderr; also PYTHONUNBUFFERED=x see man page for details on internal buffering relating to '-u'

Here is the relevant doc.

var msg = "test" jQuery.parseHTML(msg)

In my case I had to wait for a user interaction, so I set a click or touchend listener.

const isMobile = navigator.maxTouchPoints || "ontouchstart" in document.documentElement;

function play(){
    audioEl.play()
}


document.body.addEventListener(isMobile ? "touchend" : "click", play, { once: true });

just use abs for converting unsigned to signed in python

 a=-12
b=abs(a)
print(b)

Output: 12

I was also having a similar problem. Finally found one solution at https://techmeals.com/fe/questions/htmlcss/4/How-to-customize-the-select-drop-down-in-css-which-works-for-all-the-browsers

Note:

1) For Firefox support there is special CSS handling for SELECT element's parent, please take a closer look.

2) Download the down.png from Down.png

CSS code

        /* For Firefox browser we need to style for SELECT element parent. */

        @-moz-document url-prefix() {

            /* Please note this is the parent of "SELECT" element */

            .select-example {   
                background: url('https://techmeals.com/external/images/down.png');

                background-size: auto 6px;
                background-repeat: no-repeat;
                background-position: 96% 13px;
            }
        }

Building on @Tim's example to make a self-contained method:

import java.io.BufferedReader;
import java.io.File;
import java.io.InputStreamReader;
import java.util.ArrayList;

public class Shell {

    /** Returns null if it failed for some reason.
     */
    public static ArrayList<String> command(final String cmdline,
    final String directory) {
        try {
            Process process = 
                new ProcessBuilder(new String[] {"bash", "-c", cmdline})
                    .redirectErrorStream(true)
                    .directory(new File(directory))
                    .start();

            ArrayList<String> output = new ArrayList<String>();
            BufferedReader br = new BufferedReader(
                new InputStreamReader(process.getInputStream()));
            String line = null;
            while ( (line = br.readLine()) != null )
                output.add(line);

            //There should really be a timeout here.
            if (0 != process.waitFor())
                return null;

            return output;

        } catch (Exception e) {
            //Warning: doing this is no good in high quality applications.
            //Instead, present appropriate error messages to the user.
            //But it's perfectly fine for prototyping.

            return null;
        }
    }

    public static void main(String[] args) {
        test("which bash");

        test("find . -type f -printf '%T@\\\\t%p\\\\n' "
            + "| sort -n | cut -f 2- | "
            + "sed -e 's/ /\\\\\\\\ /g' | xargs ls -halt");

    }

    static void test(String cmdline) {
        ArrayList<String> output = command(cmdline, ".");
        if (null == output)
            System.out.println("\n\n\t\tCOMMAND FAILED: " + cmdline);
        else
            for (String line : output)
                System.out.println(line);

    }
}

(The test example is a command that lists all files in a directory and its subdirectories, recursively, in chronological order.)

By the way, if somebody can tell me why I need four and eight backslashes there, instead of two and four, I can learn something. There is one more level of unescaping happening than what I am counting.

Edit: Just tried this same code on Linux, and there it turns out that I need half as many backslashes in the test command! (That is: the expected number of two and four.) Now it's no longer just weird, it's a portability problem.

These are the breaking changes from Python 3.x and Python 2.x

For Python3.x use

dictlist = []
for key, value in dict.items():
    temp = [key,value]
    dictlist.append(temp)

For Python 2.7 use

dictlist = []
for key, value in dict.iteritems():
    temp = [key,value]
    dictlist.append(temp)
