Wrap your ListView in an Expanded widget

 Expanded(child:MyListView())

As stated in the above answers, it's always a good practice to initialize the variables, but if you have something which you don't know what value should it takes, and you want to leave it uninitialized so you have to make sure that you are updating it before using it.

For example: Assume we have double _bmi; and you don't know what value should it takes, so you can leave it as it is, but before using it, you have to update its value first like calling a function that calculating BMI like follows:

String calculateBMI (){
_bmi = weight / pow( height/100, 2);
return _bmi.toStringAsFixed(1);}

or whatever, what I mean is, you can leave the variable as it is, but before using it make sure you have initialized it using whatever the method you are using.

Thanks guys for help. From your suggestions i reached a solution like this.

new LayoutBuilder(
        builder:
            (BuildContext context, BoxConstraints viewportConstraints) {
          return SingleChildScrollView(
            child: ConstrainedBox(
              constraints:
                  BoxConstraints(minHeight: viewportConstraints.maxHeight),
              child: Column(children: [
             // remaining stuffs
              ]),
            ),
          );
        },
      )

You control how a row or column aligns its children using the mainAxisAlignment and crossAxisAlignment properties. For a row, the main axis runs horizontally and the cross axis runs vertically. For a column, the main axis runs vertically and the cross axis runs horizontally.

 mainAxisAlignment: MainAxisAlignment.center,
 crossAxisAlignment: CrossAxisAlignment.center,

You can use PreferredSize:

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Example',
      home: Scaffold(
        appBar: PreferredSize(
          preferredSize: Size.fromHeight(50.0), // here the desired height
          child: AppBar(
            // ...
          )
        ),
        body: // ...
      )
    );
  }
}

their is no need to create asset directory and under it images directory and then you put image. Better is to just create Images directory inside your project where pubspec.yaml exist and put images inside it and access that images just like as shown in tutorial/documention

assets: - images/lake.jpg // inside pubspec.yaml

create file name (app_config.dart) in folder name(responsive_screen) in lib folder:

import 'package:flutter/material.dart';

class AppConfig {
  BuildContext _context;
  double _height;
  double _width;
  double _heightPadding;
  double _widthPadding;

  AppConfig(this._context) {
    MediaQueryData _queryData = MediaQuery.of(_context);
    _height = _queryData.size.height / 100.0;
    _width = _queryData.size.width / 100.0;
    _heightPadding =
    _height - ((_queryData.padding.top + _queryData.padding.bottom) / 100.0);
    _widthPadding =
      _width - (_queryData.padding.left + _queryData.padding.right) / 100.0;
  }

  double rH(double v) {
   return _height * v;
  }

  double rW(double v) {
    return _width * v;
  }

  double rHP(double v) {
    return _heightPadding * v;
  }

 double rWP(double v) {
   return _widthPadding * v;
 }
}

then:

import 'responsive_screen/app_config.dart';
 ...
class RandomWordsState extends State<RandomWords> {
  AppConfig _ac;
  ...
  @override
  Widget build(BuildContext context) {
    _ac = AppConfig(context);
    ...
    return Scaffold(
      body: Container(
        height: _ac.rHP(50),
        width: _ac.rWP(50),
        color: Colors.red,
        child: Text('Test'),
      ),
    );
    ...
  }

Here is the solution which worked for me.

OUTPUT: State of Cart Widget is updated, upon addition of items.

Create a globalKey for the widget you want to update by calling the trigger from anywhere

final GlobalKey<CartWidgetState> cartKey = GlobalKey();

Make sure it's saved in a file have global access such that, it can be accessed from anywhere. I save it in globalClass where is save commonly used variables through the app's state.

class CartWidget extends StatefulWidget {

  CartWidget({Key key}) : super(key: key);
  @override
  CartWidgetState createState() => CartWidgetState();
}

class CartWidgetState extends State<CartWidget> {
  @override
  Widget build(BuildContext context) {
    //return your widget
    return Container();
  }
}

Call your widget from some other class.

class HomeScreen extends StatefulWidget {

  HomeScreen ({Key key}) : super(key: key);
  @override
  HomeScreenState createState() => HomeScreen State();
}

class HomeScreen State extends State<HomeScreen> {
  @override
  Widget build(BuildContext context) {
    return ListView(
              children:[
                 ChildScreen(), 
                 CartWidget(key:cartKey)
              ]
            );
  }
}



class ChildScreen extends StatefulWidget {

  ChildScreen ({Key key}) : super(key: key);
  @override
  ChildScreenState createState() => ChildScreen State();
}

class ChildScreen State extends State<ChildScreen> {
  @override
  Widget build(BuildContext context) {
    return InkWell(
              onTap: (){
                // This will update the state of your inherited widget/ class
                if (cartKey.currentState != null)
                    cartKey.currentState.setState(() {});
              },
              child: Text("Update The State of external Widget"),
           );
  }
}

In flutter, there are a few ways to deal with Asynchronous actions.

A lazy way to do it can be using a modal. Which will block the user input, thus preventing any unwanted actions. This would require very little change to your code. Just modifying your _onLoading to something like this :

void _onLoading() {
  showDialog(
    context: context,
    barrierDismissible: false,
    builder: (BuildContext context) {
      return Dialog(
        child: new Row(
          mainAxisSize: MainAxisSize.min,
          children: [
            new CircularProgressIndicator(),
            new Text("Loading"),
          ],
        ),
      );
    },
  );
  new Future.delayed(new Duration(seconds: 3), () {
    Navigator.pop(context); //pop dialog
    _login();
  });
}

The most ideal way to do it is using FutureBuilder and a stateful widget. Which is what you started. The trick is that, instead of having a boolean loading = false in your state, you can directly use a Future<MyUser> user

And then pass it as argument to FutureBuilder, which will give you some info such as "hasData" or the instance of MyUser when completed.

This would lead to something like this :

@immutable
class MyUser {
  final String name;

  MyUser(this.name);
}

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
      title: 'Flutter Demo',
      home: new MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  MyHomePage({Key key, this.title}) : super(key: key);

  final String title;

  @override
  _MyHomePageState createState() => new _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  Future<MyUser> user;

  void _logIn() {
    setState(() {
      user = new Future.delayed(const Duration(seconds: 3), () {
        return new MyUser("Toto");
      });
    });
  }

  Widget _buildForm(AsyncSnapshot<MyUser> snapshot) {
    var floatBtn = new RaisedButton(
      onPressed:
          snapshot.connectionState == ConnectionState.none ? _logIn : null,
      child: new Icon(Icons.save),
    );
    var action =
        snapshot.connectionState != ConnectionState.none && !snapshot.hasData
            ? new Stack(
                alignment: FractionalOffset.center,
                children: <Widget>[
                  floatBtn,
                  new CircularProgressIndicator(
                    backgroundColor: Colors.red,
                  ),
                ],
              )
            : floatBtn;

    return new ListView(
      padding: const EdgeInsets.all(15.0),
        children: <Widget>[
          new ListTile(
            title: new TextField(),
          ),
          new ListTile(
            title: new TextField(obscureText: true),
          ),
          new Center(child: action)
        ],
    );
  }

  @override
  Widget build(BuildContext context) {
    return new FutureBuilder(
      future: user,
      builder: (context, AsyncSnapshot<MyUser> snapshot) {
        if (snapshot.hasData) {
          return new Scaffold(
            appBar: new AppBar(
              title: new Text("Hello ${snapshot.data.name}"),
            ),
          );
        } else {
          return new Scaffold(
            appBar: new AppBar(
              title: new Text("Connection"),
            ),
            body: _buildForm(snapshot),
          );
        }
      },
    );
  }
}

You can use Flex and Flexible widgets. for example:

Flex(
direction: Axis.vertical,
children: <Widget>[
    ... other widgets ...
    Flexible(
        flex: 1,
        child: ListView.builder(
        itemCount: ...,
        itemBuilder: (context, index) {
            ...
        },
        ),
    ),
],

);

To dismiss the keyboard (1.7.8+hotfix.2 and above) just call the method below:

FocusScope.of(context).unfocus();

Once the FocusScope.of(context).unfocus() method already check if there is focus before dismiss the keyboard it's not needed to check it. But in case you need it just call another context method: FocusScope.of(context).hasPrimaryFocus

The AppBar widget has a property called automaticallyImplyLeading. By default it's value is true. If you don't want flutter automatically build the back button for you then just make the property false.

appBar: AppBar(
  title: Text("YOUR_APPBAR_TITLE"), 
  automaticallyImplyLeading: false,
),

To add your custom back button

appBar: AppBar(
  title: Text("YOUR_APPBAR_TITLE"), 
  automaticallyImplyLeading: false,
  leading: YOUR_CUSTOM_WIDGET(),
),

If you simply place text as a child(ren) of a column, this is the easiest way to have text automatically wrap. Assuming you don't have anything more complicated going on. In those cases, I would think you would create your container sized as you see fit and put another column inside and then your text. This seems to work nicely. Containers want to shrink to the size of its contents, and this seems to naturally conflict with wrapping, which requires more effort.

Column(
  mainAxisSize: MainAxisSize.min,
  children: <Widget>[
    Text('This long text will wrap very nicely if there isn't room beyond the column\'s total width and if you have enough vertical space available to wrap into.',
      style: TextStyle(fontSize: 16, color: primaryColor),
      textAlign: TextAlign.center,),
  ],
),

I also had this problem and it's solved as change line from res/values/styles.xml

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">

to

1. <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
2. <style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">

both solutions worked

There's a hook called useLocation in react-router v5, no need for HOC or other stuff, it's very succinctly and convenient.

import { useLocation } from 'react-router-dom';

const ExampleComponent: React.FC = () => {
  const location = useLocation();  

  return (
    <Router basename='/app'>
      <main>
        <AppBar handleMenuIcon={this.handleMenuIcon} title={location.pathname} />
      </main>
    </Router>
  );
}

you just add this style in your style.xml file which is in your values folder

<style name="AppTheme.NoActionBar" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
    <item name="android:windowFullscreen">true</item>
</style>

After that set this style to your activity class in your AndroidManifest.xml file

android:theme="@style/AppTheme.NoActionBar"

Edit:- If you are going with programmatic way to hide ActionBar then use below code in your activity onCreate() method.

if(getSupportedActionbar()!=null)    
     this.getSupportedActionBar().hide();

and if you want to hide ActionBar from Fragment then

getActivity().getSupportedActionBar().hide();

AppCompat v7:- Use following theme in your Activities where you don't want actiobBar Theme.AppComat.NoActionBar or Theme.AppCompat.Light.NoActionBar or if you want to hide in whole app then set this theme in your <application... /> in your AndroidManifest.

In Kotlin:

add this line of code in your onCreate() method or you can use above theme.

if (supportActionBar != null)
        supportActionBar?.hide()

i hope this will help you more.

After ensuring the naming conventions are correct as described in other answers, and also trying to invalidate the cache and restart, deleting temp/cache folders the issue still persisted for me.

I got rid of it as follows: Add a new dummy XML resource. This will trigger bindings and its meta-data to re-create across the project. The annoying compile errors should no longer be visible anymore. You now delete the dummy XML you added.

For me as of August 2020, the Binding would automatically get corrupted repeatedly. It seems to be biting more than it can chew under the hood.

I would like to suggest to use a single RecyclerView and populate your list items dynamically. I've added a github project to describe how this can be done. You might have a look. While the other solutions will work just fine, I would like to suggest, this is a much faster and efficient way of showing multiple lists in a RecyclerView.

The idea is to add logic in your onCreateViewHolder and onBindViewHolder method so that you can inflate proper view for the exact positions in your RecyclerView.

I've added a sample project along with that wiki too. You might clone and check what it does. For convenience, I am posting the adapter that I have used.

public class DynamicListAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {

    private static final int FOOTER_VIEW = 1;
    private static final int FIRST_LIST_ITEM_VIEW = 2;
    private static final int FIRST_LIST_HEADER_VIEW = 3;
    private static final int SECOND_LIST_ITEM_VIEW = 4;
    private static final int SECOND_LIST_HEADER_VIEW = 5;

    private ArrayList<ListObject> firstList = new ArrayList<ListObject>();
    private ArrayList<ListObject> secondList = new ArrayList<ListObject>();

    public DynamicListAdapter() {
    }

    public void setFirstList(ArrayList<ListObject> firstList) {
        this.firstList = firstList;
    }

    public void setSecondList(ArrayList<ListObject> secondList) {
        this.secondList = secondList;
    }

    public class ViewHolder extends RecyclerView.ViewHolder {
        // List items of first list
        private TextView mTextDescription1;
        private TextView mListItemTitle1;

        // List items of second list
        private TextView mTextDescription2;
        private TextView mListItemTitle2;

        // Element of footer view
        private TextView footerTextView;

        public ViewHolder(final View itemView) {
            super(itemView);

            // Get the view of the elements of first list
            mTextDescription1 = (TextView) itemView.findViewById(R.id.description1);
            mListItemTitle1 = (TextView) itemView.findViewById(R.id.title1);

            // Get the view of the elements of second list
            mTextDescription2 = (TextView) itemView.findViewById(R.id.description2);
            mListItemTitle2 = (TextView) itemView.findViewById(R.id.title2);

            // Get the view of the footer elements
            footerTextView = (TextView) itemView.findViewById(R.id.footer);
        }

        public void bindViewSecondList(int pos) {

            if (firstList == null) pos = pos - 1;
            else {
                if (firstList.size() == 0) pos = pos - 1;
                else pos = pos - firstList.size() - 2;
            }

            final String description = secondList.get(pos).getDescription();
            final String title = secondList.get(pos).getTitle();

            mTextDescription2.setText(description);
            mListItemTitle2.setText(title);
        }

        public void bindViewFirstList(int pos) {

            // Decrease pos by 1 as there is a header view now.
            pos = pos - 1;

            final String description = firstList.get(pos).getDescription();
            final String title = firstList.get(pos).getTitle();

            mTextDescription1.setText(description);
            mListItemTitle1.setText(title);

        } else if (secondListSize > 0 && firstListSize == 0) {
            if (position == 0) return SECOND_LIST_HEADER_VIEW;
            else if (position == secondListSize + 1) return FOOTER_VIEW;
            else return SECOND_LIST_ITEM_VIEW;

        } else if (secondListSize == 0 && firstListSize > 0) {
            if (position == 0) return FIRST_LIST_HEADER_VIEW;
            else return FIRST_LIST_ITEM_VIEW;
        }

        return super.getItemViewType(position);
    }
}

There is another way of keeping your items in a single ArrayList of objects so that you can set an attribute tagging the items to indicate which item is from first list and which one belongs to second list. Then pass that ArrayList into your RecyclerView and then implement the logic inside adapter to populate them dynamically.

Hope that helps.

I managed to fix this by adding:

android:layout_marginTop="?android:attr/actionBarSize"

to the FrameLayout like so:

 <FrameLayout
        android:id="@+id/content"
        android:layout_marginTop="?android:attr/actionBarSize"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
       />

You can add it as script file. save the txt file with js suffix

in the head section add

<script src="fileName.js"></script>

Extract characters from a string:

var str = "Hello world!";
var res = str.substring(1,4);

The result of res will be:

ell

$('.dep_buttons').mouseover(function(){
    $(this).text().substring(0,25);
    if($(this).text().length > 30) {
        $(this).stop().animate({height:"150px"},150);
    }
    $(".dep_buttons").mouseout(function(){
        $(this).stop().animate({height:"40px"},150);
    });
});

Found an XML transform stylesheet here (wayback machine link, site itself is in german)

The stylesheet added here could be helpful:

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text" encoding="iso-8859-1"/>

<xsl:strip-space elements="*" />

<xsl:template match="/*/child::*">
<xsl:for-each select="child::*">
<xsl:if test="position() != last()">"<xsl:value-of select="normalize-space(.)"/>",    </xsl:if>
<xsl:if test="position()  = last()">"<xsl:value-of select="normalize-space(.)"/>"<xsl:text>&#xD;</xsl:text>
</xsl:if>
</xsl:for-each>

Perhaps you want to remove the quotes inside the xsl:if tags so it doesn't put your values into quotes, depending on where you want to use the CSV file.

No need for external libs to bloat things - especially when working with Android. Here is a native solution that does the trick. This is a pice of code from an app that stores a byte array as an image file.

    // Byte array with image data.
    final byte[] imageData = params[0];

    // Write bytes to tmp file.
    final File tmpImageFile = new File(ApplicationContext.getInstance().getCacheDir(), "scan.jpg");
    FileOutputStream tmpOutputStream = null;
    try {
        tmpOutputStream = new FileOutputStream(tmpImageFile);
        tmpOutputStream.write(imageData);
        Log.d(TAG, "File successfully written to tmp file");
    }
    catch (FileNotFoundException e) {
        Log.e(TAG, "FileNotFoundException: " + e);
        return null;
    }
    catch (IOException e) {
        Log.e(TAG, "IOException: " + e);
        return null;
    }
    finally {
        if(tmpOutputStream != null)
            try {
                tmpOutputStream.close();
            } catch (IOException e) {
                Log.e(TAG, "IOException: " + e);
            }
    }

This can also arise in connection with a bug in certain versions of Percona Toolkit's online-schema-change tool. To mutate a large table, pt-osc first creates a duplicate table and copies all the records into it. Under some circumstances, some versions of pt-osc 2.2.x will try to give the constraints on the new table the same names as the constraints on the old table.

A fix was released in 2.3.0.

See https://bugs.launchpad.net/percona-toolkit/+bug/1498128 for more details.

Done by having it like that:

view = inflater.inflate(R.layout.entry_detail, container, false);
TextView tp1= (TextView) view.findViewById(R.id.tp1);
LinearLayout layone= (LinearLayout) view.findViewById(R.id.layone);
tp1.setVisibility(View.VISIBLE);
layone.setVisibility(View.VISIBLE);

suppose that

x = [
    [-5.01,-5.43,1.08,0.86,-2.67,4.94,-2.51,-2.25,5.56,1.03],
    [-8.12,-3.48,-5.52,-3.78,0.63,3.29,2.09,-2.13,2.86,-3.33],
    [-3.68,-3.54,1.66,-4.11,7.39,2.08,-2.59,-6.94,-2.26,4.33]
]

you can notice that x has dimension 3*10 if you need to get the mean to each row you can type this

theMean = np.mean(x1,axis=1)

don't forget to import numpy as np

I have something like this:

import org.apache.http.NameValuePair;
import org.apache.http.client.utils.URIBuilder;

private String getParamValue(String link, String paramName) throws URISyntaxException {
        List<NameValuePair> queryParams = new URIBuilder(link).getQueryParams();
        return queryParams.stream()
                .filter(param -> param.getName().equalsIgnoreCase(paramName))
                .map(NameValuePair::getValue)
                .findFirst()
                .orElse("");
    }

I would use an asynchronous access using a completion block.

This example saves the Google logo to the document directory of the device. (iOS 5+, OSX 10.7+)

NSString *documentDir = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject];
NSString *filePath = [documentDir stringByAppendingPathComponent:@"GoogleLogo.png"];

NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"https://www.google.com/images/srpr/logo11w.png"]];
[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue currentQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
    if (error) {
        NSLog(@"Download Error:%@",error.description);
    }
    if (data) {
        [data writeToFile:filePath atomically:YES];
        NSLog(@"File is saved to %@",filePath);
    }
}];

Found on Bytes.com:

string temp = mystring.Replace('\n', '\0');// '\0' represents an empty char

First of all you use here two strings: "" marks a string it may be ""-empty "s"- string of lenght 1 or "aaa" string of lenght 3, while '' marks chars . In order to be able to do String str = "a" + "aaa" + 'a' you must use method Character.toString(char c) as @Thomas Keene said so an example would be String str = "a" + "aaa" + Character.toString('a')

you can always hide or show the tabpage.

'in VB
myTabControl.TabPages(9).Hide() 'to hide the tabpage that has index 9
myTabControl.TabPages(9).Show() 'to show the tabpage that has index 9

I ran into this issue as well. I don't know the technical details of what was actually happening. However, in my situation, the root cause was that there was cascading deletes setup in the Oracle database and my JPA/Hibernate code was also trying to do the cascading delete calls. So my advice is to make sure that you know exactly what is happening.

So my solution was to also set localStorage when setting my state and then get the value from localStorage again inside of the getInitialState callback like so:

getInitialState: function() {
    var selectedOption = localStorage.getItem( 'SelectedOption' ) || 1;

    return {
        selectedOption: selectedOption
    };
},

setSelectedOption: function( option ) {
    localStorage.setItem( 'SelectedOption', option );
    this.setState( { selectedOption: option } );
}

I'm not sure if this can be considered an Anti-Pattern but it works unless there is a better solution.

One unit testing framework in C is Check; a list of unit testing frameworks in C can be found here and is reproduced below. Depending on how many standard library functions your runtime has, you may or not be able to use one of those.

AceUnit

AceUnit (Advanced C and Embedded Unit) bills itself as a comfortable C code unit test framework. It tries to mimick JUnit 4.x and includes reflection-like capabilities. AceUnit can be used in resource constraint environments, e.g. embedded software development, and importantly it runs fine in environments where you cannot include a single standard header file and cannot invoke a single standard C function from the ANSI / ISO C libraries. It also has a Windows port. It does not use forks to trap signals, although the authors have expressed interest in adding such a feature. See the AceUnit homepage.

GNU Autounit

Much along the same lines as Check, including forking to run unit tests in a separate address space (in fact, the original author of Check borrowed the idea from GNU Autounit). GNU Autounit uses GLib extensively, which means that linking and such need special options, but this may not be a big problem to you, especially if you are already using GTK or GLib. See the GNU Autounit homepage.

cUnit

Also uses GLib, but does not fork to protect the address space of unit tests.

CUnit

Standard C, with plans for a Win32 GUI implementation. Does not currently fork or otherwise protect the address space of unit tests. In early development. See the CUnit homepage.

CuTest

A simple framework with just one .c and one .h file that you drop into your source tree. See the CuTest homepage.

CppUnit

The premier unit testing framework for C++; you can also use it to test C code. It is stable, actively developed, and has a GUI interface. The primary reasons not to use CppUnit for C are first that it is quite big, and second you have to write your tests in C++, which means you need a C++ compiler. If these don’t sound like concerns, it is definitely worth considering, along with other C++ unit testing frameworks. See the CppUnit homepage.

embUnit

embUnit (Embedded Unit) is another unit test framework for embedded systems. This one appears to be superseded by AceUnit. Embedded Unit homepage.

MinUnit

A minimal set of macros and that’s it! The point is to show how easy it is to unit test your code. See the MinUnit homepage.

CUnit for Mr. Ando

A CUnit implementation that is fairly new, and apparently still in early development. See the CUnit for Mr. Ando homepage.

This list was last updated in March 2008.

More frameworks:

CMocka

CMocka is a test framework for C with support for mock objects. It's easy to use and setup.

See the CMocka homepage.

Criterion

Criterion is a cross-platform C unit testing framework supporting automatic test registration, parameterized tests, theories, and that can output to multiple formats, including TAP and JUnit XML. Each test is run in its own process, so signals and crashes can be reported or tested if needed.

See the Criterion homepage for more information.

HWUT

HWUT is a general Unit Test tool with great support for C. It can help to create Makefiles, generate massive test cases coded in minimal 'iteration tables', walk along state machines, generate C-stubs and more. The general approach is pretty unique: Verdicts are based on 'good stdout/bad stdout'. The comparison function, though, is flexible. Thus, any type of script may be used for checking. It may be applied to any language that can produce standard output.

See the HWUT homepage.

CGreen

A modern, portable, cross-language unit testing and mocking framework for C and C++. It offers an optional BDD notation, a mocking library, the ability to run it in a single process (to make debugging easier). A test runner which discover automatically the test functions is available. But you can create your own programmatically.

All those features (and more) are explained in the CGreen manual.

Wikipedia gives a detailed list of C unit testing frameworks under List of unit testing frameworks: C

From the API (http://msdn.microsoft.com/en-us/library/system.datetime_members(VS.71).aspx) it does not seem it can show the name of the time zone used.

jQuery Mobile >= 1.4

Create a custom class, e.g. .custom-btn. Note that to override jQM styles without using !important, CSS hierarchy should be respected. .ui-btn.custom-class or .ui-input-btn.custom-class.

.ui-input-btn.custom-btn {
   border:1px solid red;
   text-decoration:none;
   font-family:helvetica;
   color:red;
   background:url(img.png) repeat-x;
}

Add a data-wrapper-class to input. The custom class will be added to input wrapping div.

<input type="button" data-wrapper-class="custom-btn">

Demo

jQuery Mobile <= 1.3

Input button is wrapped by a DIV with class ui-btn. You need to select that div and the input[type="submit"]. Using !important is essential to override Jquery Mobile styles.

Demo

div.ui-btn, input[type="submit"] {
 border:1px solid red !important;
 text-decoration:none !important;
 font-family:helvetica !important;
 color:red !important;
 background:url(../images/btn_hover.png) repeat-x !important;
}

To get the current time in the local timezone as a naive datetime object:

from datetime import datetime
naive_dt = datetime.now()

If it doesn't return the expected time then it means that your computer is misconfigured. You should fix it first (it is unrelated to Python).

To get the current time in UTC as a naive datetime object:

naive_utc_dt = datetime.utcnow()

To get the current time as an aware datetime object in Python 3.3+:

from datetime import datetime, timezone

utc_dt = datetime.now(timezone.utc) # UTC time
dt = utc_dt.astimezone() # local time

To get the current time in the given time zone from the tz database:

import pytz

tz = pytz.timezone('Europe/Berlin')
berlin_now = datetime.now(tz)

It works during DST transitions. It works if the timezone had different UTC offset in the past i.e., it works even if the timezone corresponds to multiple tzinfo objects at different times.

I understood that you want to remove from the array using a condition and have another array that has items removed from the array. Is right?

How about this?

var review = ['a', 'b', 'c', 'ab', 'bc'];_x000D_
var filtered = [];_x000D_
for(var i=0; i < review.length;) {_x000D_
  if(review[i].charAt(0) == 'a') {_x000D_
    filtered.push(review.splice(i,1)[0]);_x000D_
  }else{_x000D_
    i++;_x000D_
  }_x000D_
}_x000D_
_x000D_
console.log("review", review);_x000D_
console.log("filtered", filtered);

Hope this help...

By the way, I compared 'for-loop' to 'forEach'.

If remove in case a string contains 'f', a result is different.

And remove by each iteration, also a result is different.

TL;DR

If you have any doubt, use merge.

Short Answer

The only differences between a rebase and a merge are:

• The resulting tree structure of the history (generally only noticeable when looking at a commit graph) is different (one will have branches, the other won't).
• Merge will generally create an extra commit (e.g. node in the tree).
• Merge and rebase will handle conflicts differently. Rebase will present conflicts one commit at a time where merge will present them all at once.

So the short answer is to pick rebase or merge based on what you want your history to look like.

Long Answer

There are a few factors you should consider when choosing which operation to use.

Is the branch you are getting changes from shared with other developers outside your team (e.g. open source, public)?

If so, don't rebase. Rebase destroys the branch and those developers will have broken/inconsistent repositories unless they use git pull --rebase. This is a good way to upset other developers quickly.

How skilled is your development team?

Rebase is a destructive operation. That means, if you do not apply it correctly, you could lose committed work and/or break the consistency of other developer's repositories.

I've worked on teams where the developers all came from a time when companies could afford dedicated staff to deal with branching and merging. Those developers don't know much about Git and don't want to know much. In these teams I wouldn't risk recommending rebasing for any reason.

Does the branch itself represent useful information

Some teams use the branch-per-feature model where each branch represents a feature (or bugfix, or sub-feature, etc.) In this model the branch helps identify sets of related commits. For example, one can quickly revert a feature by reverting the merge of that branch (to be fair, this is a rare operation). Or diff a feature by comparing two branches (more common). Rebase would destroy the branch and this would not be straightforward.

I've also worked on teams that used the branch-per-developer model (we've all been there). In this case the branch itself doesn't convey any additional information (the commit already has the author). There would be no harm in rebasing.

Might you want to revert the merge for any reason?

Reverting (as in undoing) a rebase is considerably difficult and/or impossible (if the rebase had conflicts) compared to reverting a merge. If you think there is a chance you will want to revert then use merge.

Do you work on a team? If so, are you willing to take an all or nothing approach on this branch?

Rebase operations need to be pulled with a corresponding git pull --rebase. If you are working by yourself you may be able to remember which you should use at the appropriate time. If you are working on a team this will be very difficult to coordinate. This is why most rebase workflows recommend using rebase for all merges (and git pull --rebase for all pulls).

Common Myths

Merge destroys history (squashes commits)

Assuming you have the following merge:

    B -- C
   /      \
  A--------D

Some people will state that the merge "destroys" the commit history because if you were to look at the log of only the master branch (A -- D) you would miss the important commit messages contained in B and C.

If this were true we wouldn't have questions like this. Basically, you will see B and C unless you explicitly ask not to see them (using --first-parent). This is very easy to try for yourself.

Rebase allows for safer/simpler merges

The two approaches merge differently, but it is not clear that one is always better than the other and it may depend on the developer workflow. For example, if a developer tends to commit regularly (e.g. maybe they commit twice a day as they transition from work to home) then there could be a lot of commits for a given branch. Many of those commits might not look anything like the final product (I tend to refactor my approach once or twice per feature). If someone else was working on a related area of code and they tried to rebase my changes it could be a fairly tedious operation.

Rebase is cooler / sexier / more professional

If you like to alias rm to rm -rf to "save time" then maybe rebase is for you.

My Two Cents

I always think that someday I will come across a scenario where Git rebase is the awesome tool that solves the problem. Much like I think I will come across a scenario where Git reflog is an awesome tool that solves my problem. I have worked with Git for over five years now. It hasn't happened.

Messy histories have never really been a problem for me. I don't ever just read my commit history like an exciting novel. A majority of the time I need a history I am going to use Git blame or Git bisect anyway. In that case, having the merge commit is actually useful to me, because if the merge introduced the issue, that is meaningful information to me.

Update (4/2017)

I feel obligated to mention that I have personally softened on using rebase although my general advice still stands. I have recently been interacting a lot with the Angular 2 Material project. They have used rebase to keep a very clean commit history. This has allowed me to very easily see what commit fixed a given defect and whether or not that commit was included in a release. It serves as a great example of using rebase correctly.

Add this in pom.xml file. It works fine for me

There is a way to create war file of your project from eclipse.

First a create an xml file with the following code,

Replace HistoryCheck with your project name.

<?xml version="1.0" encoding="UTF-8"?>
<project name="HistoryCheck" basedir="." default="default">
    <target name="default" depends="buildwar,deploy"></target>
    <target name="buildwar">
        <war basedir="war" destfile="HistoryCheck.war" webxml="war/WEB-INF/web.xml">
            <exclude name="WEB-INF/**" />
            <webinf dir="war/WEB-INF/">
                <include name="**/*.jar" />
            </webinf>
        </war>
    </target>
    <target name="deploy">
        <copy file="HistoryCheck.war" todir="." />
    </target>
</project>

Now, In project explorer right click on that xml file and Run as-> ant build

You can see the war file of your project in your project folder.

All these answers are obsolete now.

Currently you have to:

1. install the Python language extension (and Python, obviously)
2. open folder (important!), open any Python file inside that folder
3. switch to debug "tab"(?) and click on the gearbox (with hint 'Configure of Fix 'launch.json'')
4. save the opened launch.json file (it's placed in .vscode subdirectory in the folder opened in step #2)
5. finally, click the green triangle or hit F5

No additional extensions or manual launch.json editing is required now.

Note:- below is the illustration of map and flatmap function, otherwise Optional is primarily designed to be used as a return type only.

As you already may know Optional is a kind of container which may or may not contain a single object, so it can be used wherever you anticipate a null value(You may never see NPE if use Optional properly). For example if you have a method which expects a person object which may be nullable you may want to write the method something like this:

void doSome(Optional<Person> person){
  /*and here you want to retrieve some property phone out of person
    you may write something like this:
  */
  Optional<String> phone = person.map((p)->p.getPhone());
  phone.ifPresent((ph)->dial(ph));
}
class Person{
  private String phone;
  //setter, getters
}

Here you have returned a String type which is automatically wrapped in an Optional type.

If person class looked like this, i.e. phone is also Optional

class Person{
  private Optional<String> phone;
  //setter,getter
}

In this case invoking map function will wrap the returned value in Optional and yield something like:

Optional<Optional<String>> 
//And you may want Optional<String> instead, here comes flatMap

void doSome(Optional<Person> person){
  Optional<String> phone = person.flatMap((p)->p.getPhone());
  phone.ifPresent((ph)->dial(ph));
}

PS; Never call get method (if you need to) on an Optional without checking it with isPresent() unless you can't live without NullPointerExceptions.

i got the same problem so tried so many things but finally this is the solution.

import time 

print (time.strftime("%d/%m/%Y"))

Write one! Wrapping JC's answer gives me:

randomRows = function(df,n){
   return(df[sample(nrow(df),n),])
}

Now make it better by checking first if n<=nrow(df) and stopping with an error.

// Before C++11
// I used following methods:

// 1.
int A[] = {10, 20, 30};                              // original array A

unsigned sizeOfA = sizeof(A)/sizeof(A[0]);           // calculate the number of elements

                                                     // declare vector vArrayA,
std::vector<int> vArrayA(sizeOfA);                   // make room for all
                                                     // array A integers
                                                     // and initialize them to 0 

for(unsigned i=0; i<sizeOfA; i++)
    vArrayA[i] = A[i];                               // initialize vector vArrayA


//2.
int B[] = {40, 50, 60, 70};                          // original array B

std::vector<int> vArrayB;                            // declare vector vArrayB
for (unsigned i=0; i<sizeof(B)/sizeof(B[0]); i++)
    vArrayB.push_back(B[i]);                         // initialize vArrayB

//3.
int C[] = {1, 2, 3, 4};                              // original array C

std::vector<int> vArrayC;                            // create an empty vector vArrayC
vArrayC.resize(sizeof(C)/sizeof(C[0]));              // enlarging the number of 
                                                     // contained elements
for (unsigned i=0; i<sizeof(C)/sizeof(C[0]); i++)
     vArrayC.at(i) = C[i];                           // initialize vArrayC


// A Note:
// Above methods will work well for complex arrays
// with structures as its elements.

you want these four lines of code in your Run.bat:

@echo off          //this makes it so you have an empty cmd window on startup
javac Main.java    //this compiles the .java into a .class
java Main          // this runs the .class file
pause              //this prevents the window from instantly closing after program end

<div ng-hide="myvar == null"></div>

or

<div ng-show="myvar != null"></div>

I came to this page looking for a way of getting my own ip address not the one of the remote machine connecting to me.

This will not work for a windows machine.

But in case someone searches for what I was looking for:

#! /usr/bin/php
<?php
$my_current_ip=exec("ifconfig | grep -Eo 'inet (addr:)?([0-9]*\.){3}[0-9]*' | grep -Eo '([0-9]*\.){3}[0-9]*' | grep -v '127.0.0.1'");
echo $my_current_ip;

(Shamelessly adapted from How to I get the primary IP address of the local machine on Linux and OS X?)

Another option would be to set a flag variable as a Boolean and then change that value based on your criteria.

Dim count as Integer 
Dim flag as Boolean

flag = True

While flag
    count = count + 1 

    If count = 10 Then
        'Set the flag to false         '
        flag = false
    End If 
Wend

This is how you can do it. This code assumes the existance of a buffered image called 'image' (like your comment says)

// The required drawing location
int drawLocationX = 300;
int drawLocationY = 300;

// Rotation information

double rotationRequired = Math.toRadians (45);
double locationX = image.getWidth() / 2;
double locationY = image.getHeight() / 2;
AffineTransform tx = AffineTransform.getRotateInstance(rotationRequired, locationX, locationY);
AffineTransformOp op = new AffineTransformOp(tx, AffineTransformOp.TYPE_BILINEAR);

// Drawing the rotated image at the required drawing locations
g2d.drawImage(op.filter(image, null), drawLocationX, drawLocationY, null);

When MySQL's only_full_group_by mode is turned on, it means that strict ANSI SQL rules will apply when using GROUP BY. With regard to your query, this means that if you GROUP BY of the proof_type column, then you can only select two things:

• the proof_type column, or
• aggregates of any other column

By "aggregates" of other columns, I mean using an aggregate function such as MIN(), MAX(), or AVG() with another column. So in your case the following query would be valid:

SELECT proof_type,
       MAX(id) AS max_id,
       MAX(some_col),
       MIN(some_other_col)
FROM tbl_customer_pod_uploads
WHERE load_id = '78' AND
      status = 'Active'
GROUP BY proof_type

The vast majority of MySQL GROUP BY questions which I see on SO have strict mode turned off, so the query is running, but with incorrect results. In your case, the query won't run at all, forcing you to think about what you really want to do.

Note: The ANSI SQL extends what is allowed to be selected in GROUP BY by also including columns which are functionally dependent on the column(s) being selected. An example of functional dependency would be grouping by a primary key column in a table. Since the primary key is guaranteed to be unique for every record, therefore the value of any other column would also be determined. MySQL is one of the databases which allows for this (SQL Server and Oracle do not AFAIK).

1 ) Only the copy of reference is sent as a value to the formal parameter. When the formal parameter variable is assigned other value ,the formal parameter's reference changes but the actual parameter's reference remain the same incase of this integer object.

public class UnderstandingObjects {

public static void main(String[] args) {

    Integer actualParam = new Integer(10);

    changeValue(actualParam);

    System.out.println("Output " + actualParam); // o/p =10

    IntObj obj = new IntObj();

    obj.setVal(20);

    changeValue(obj);

    System.out.println(obj.a); // o/p =200

}

private static void changeValue(Integer formalParam) {

    formalParam = 100;

    // Only the copy of reference is set to the formal parameter
    // this is something like => Integer formalParam =new Integer(100);
    // Here we are changing the reference of formalParam itself not just the
    // reference value

}

private static void changeValue(IntObj obj) {
    obj.setVal(200);

    /*
     * obj = new IntObj(); obj.setVal(200);
     */
    // Here we are not changing the reference of obj. we are just changing the
    // reference obj's value

    // we are not doing obj = new IntObj() ; obj.setValue(200); which has happend
    // with the Integer

}

}

class IntObj { Integer a;

public void setVal(int a) {
    this.a = a;
}

}

Create Table as select (CTAS) is possible in Hive.

You can try out below command:

CREATE TABLE new_test 
    row format delimited 
    fields terminated by '|' 
    STORED AS RCFile 
AS select * from source where col=1

1. Target cannot be partitioned table.
2. Target cannot be external table.
3. It copies the structure as well as the data

Create table like is also possible in Hive.

1. It just copies the source table definition.

No, you can't achieve that without setting a fixed height (or using a script).

Here are 2 answers of mine, showing how to use a script to achieve something like that:

• How to get header from cards or similar to have the same height with flex box?

• Same height for flex items in the flex-direction column flex container

This wiki page has this interesting one-liner, which reminds us that we can push several refs:

git push origin refs/tags/<old-tag>:refs/tags/<new-tag> :refs/tags/<old-tag> && git tag -d <old-tag>

and ask other cloners to do git pull --prune --tags

So the idea is to push:

• <new-tag> for every commits referenced by <old-tag>: refs/tags/<old-tag>:refs/tags/<new-tag>,
• the deletion of <old-tag>: :refs/tags/<old-tag>

See as an example "Change naming convention of tags inside a git repository?".

To change the actual local market:

Basically the market is determined automatically based on your IP. You can change some local country settings from your Gmail account settings but still IP of the country you're browsing from is more important. To go around it you'd have to Proxy-cheat. Check out some ways/sites: http://www.affilorama.com/forum/market-research/how-to-change-country-search-settings-in-google-t4160.html

To do it from an Android phone you'd need to find an app. I don't have my Droid anymore but give this a try: http://forum.xda-developers.com/showthread.php?t=694720

$.upload( form.action, new FormData( myForm))
.progress( function( progressEvent, upload) {
    if( progressEvent.lengthComputable) {
        var percent = Math.round( progressEvent.loaded * 100 / progressEvent.total) + '%';

I had the same issue and the below steps helped me fix the issue.

1. Find out the apache user - created a test.php file in the public folder with the code

<?php echo exec('whoami'); ?>

And run the file from the web browser. It would give the apache user. In my case, it is ec2-user as I was using the aws with cronjob installed in /etc/cron.d/. It could be different user for others.

2. Run the below command on the command line.

sudo chown -R ec2-user:<usergroup> /app-path/public

You need to identify and use the right "user" and "usergroup" here.

Try this:

$("#myId > UL > LI")

For completeness, we should mention PEP3119 where ABC was introduced and compared with interfaces, and original Talin's comment.

The abstract class is not perfect interface:

• belongs to the inheritance hierarchy
• is mutable

But if you consider writing it your own way:

def some_function(self):
     raise NotImplementedError()

interface = type(
    'your_interface', (object,),
    {'extra_func': some_function,
     '__slots__': ['extra_func', ...]
     ...
     '__instancecheck__': your_instance_checker,
     '__subclasscheck__': your_subclass_checker
     ...
    }
)

ok, rather as a class
or as a metaclass
and fighting with python to achieve the immutable object
and doing refactoring
...

you'll quite fast realize that you're inventing the wheel to eventually achieve abc.ABCMeta

abc.ABCMeta was proposed as a useful addition of the missing interface functionality, and that's fair enough in a language like python.

Certainly, it was able to be enhanced better whilst writing version 3, and adding new syntax and immutable interface concept ...

Conclusion:

The abc.ABCMeta IS "pythonic" interface in python

From Stack Overflow question What is the Python 3 equivalent of "python -m SimpleHTTPServer":

The following works for me:

python -m http.server [<portNo>]

Because I am using Python 3 the module SimpleHTTPServer has been replaced by http.server, at least in Windows.

df.loc will do the job :

>>> df = pd.DataFrame(np.random.randn(3, 2), columns=['A','B'])
>>> df
          A         B
0 -0.269036  0.534991
1  0.069915 -1.173594
2 -1.177792  0.018381
>>> df.loc[13] = df.loc[1]
>>> df
           A         B
0  -0.269036  0.534991
1   0.069915 -1.173594
2  -1.177792  0.018381
13  0.069915 -1.173594

If you can create your sql statement dynamically you can do following workaround:

String myArray[][] = { { "1-1", "1-2" }, { "2-1", "2-2" }, { "3-1", "3-2" } };

StringBuffer mySql = new StringBuffer("insert into MyTable (col1, col2) values (?, ?)");

for (int i = 0; i < myArray.length - 1; i++) {
    mySql.append(", (?, ?)");
}

myStatement = myConnection.prepareStatement(mySql.toString());

for (int i = 0; i < myArray.length; i++) {
    myStatement.setString(i, myArray[i][1]);
    myStatement.setString(i, myArray[i][2]);
}
myStatement.executeUpdate();

If you only want to perform some specific operations by your second SP and do not require values back from the SP then simply do:

Exec secondSPName  @anyparams

Else, if you need values returned by your second SP inside your first one, then create a temporary table variable with equal numbers of columns and with same definition of column return by second SP. Then you can get these values in first SP as:

Insert into @tep_table
Exec secondSPName @anyparams

Update:

To pass parameter to second sp, do this:

Declare @id ID_Column_datatype 
Set @id=(Select id from table_1 Where yourconditions)

Exec secondSPName @id

Update 2:

Suppose your second sp returns Id and Name where type of id is int and name is of varchar(64) type.

now, if you want to select these values in first sp then create a temporary table variable and insert values into it:

Declare @tep_table table
(
  Id int,
  Name varchar(64)
)
Insert into @tep_table
Exec secondSP

Select * From @tep_table

This will return you the values returned by second SP.

Hope, this clear all your doubts.

This is how I understood it:

In Object oriented programming, we have something called classes. What are they for? They are to store some state and to store some methods to change that state i.e., they are encapsulating state and its methods.

It(class) does not care about the visibility of its own or of its contents. If we choose to hide the state or some methods, it is information hiding.

Now, take the scenario of an inheritance. We have a base class and a couple of derived (inherited) classes. So, what is the base class doing here? It is abstracting out some things from the derived classes.

All of them are different, right? But, we mix them up to write good object oriented programs. Hope it helps :)

First execute the below command:

sp_who2

After that execute the below command with SPID, which you got from above command:

KILL {SPID value}

There is angular service written angular file server Uses FileSaver.js and Blob.js

 vm.download = function(text) {
    var data = new Blob([text], { type: 'text/plain;charset=utf-8' });
    FileSaver.saveAs(data, 'text.txt');
  };

You can use this function trim_indent.

import re


def trim_indent(s: str):
    s = re.sub(r'^\n+', '', s)
    s = re.sub(r'\n+$', '', s)
    spaces = re.findall(r'^ +', s, flags=re.MULTILINE)
    if len(spaces) > 0 and len(re.findall(r'^[^\s]', s, flags=re.MULTILINE)) == 0:
        s = re.sub(r'^%s' % (min(spaces)), '', s, flags=re.MULTILINE)
    return s


print(trim_indent("""


        line one
            line two
                line three
            line two
        line one


"""))

Result:

"""
line one
    line two
        line three
    line two
line one
"""

The bracket notation allows you to access properties by name stored in a variable:

var obj = { "abc" : "hello" };
var x = "abc";
var y = obj[x];
console.log(y); //output - hello

obj.x would not work in this case.

Try switching the theme in the design view to one of the options in "Manifest Themes". I'm guessing this is Because you are inheriting the theme from the manifest to support multiple api levels. It worked for me anyway.

This is an extension to Pache's answer using Guava's ListenableFuture.

In particular, Futures.transform() returns ListenableFuture so can be used to chain async calls. Futures.addCallback() returns void, so cannot be used for chaining, but is good for handling success/failure on an async completion.

// ListenableFuture1: Open Database
ListenableFuture<Database> database = service.submit(() -> openDatabase());

// ListenableFuture2: Query Database for Cursor rows
ListenableFuture<Cursor> cursor =
    Futures.transform(database, database -> database.query(table, ...));

// ListenableFuture3: Convert Cursor rows to List<Foo>
ListenableFuture<List<Foo>> fooList =
    Futures.transform(cursor, cursor -> cursorToFooList(cursor));

// Final Callback: Handle the success/errors when final future completes
Futures.addCallback(fooList, new FutureCallback<List<Foo>>() {
  public void onSuccess(List<Foo> foos) {
    doSomethingWith(foos);
  }
  public void onFailure(Throwable thrown) {
    log.error(thrown);
  }
});

NOTE: In addition to chaining async tasks, Futures.transform() also allows you to schedule each task on a separate executor (Not shown in this example).

Using Python will be one easy way to achieve what you want.

I found one using Google.

"convert from json to csv using python" is an example.

            field2: {
                required: true,
                minlength: 5
            }
        }
    });

});

A more appropriate approach is to specify a Locale region as a parameter in the constructor. The example below uses a US Locale region. Date formatting is locale-sensitive and uses the Locale to tailor information relative to the customs and conventions of the user's region Locale (Java Platform SE 7)

String timeStamp = new SimpleDateFormat("yyyy.MM.dd.HH.mm.ss", Locale.US).format(new Date());

I've been searching the internet for RNG for a while now. Everything I saw was either TOO complex or was just not what I was looking for. After reading a few articles I was able to come up with this simple code.

{
  Random rnd = new Random(DateTime.Now.Millisecond);
  int[] b = new int[10] { 5, 8, 1, 7, 3, 2, 9, 0, 4, 6 };
  textBox1.Text = Convert.ToString(b[rnd.Next(10)])
}

Simple explanation,

1. create a 1 dimensional integer array.
2. full up the array with unordered numbers.
3. use the rnd.Next to get the position of the number that will be picked.

This works well.

To obtain a random number less than 100 use

{
  Random rnd = new Random(DateTime.Now.Millisecond);
  int[] b = new int[10] { 5, 8, 1, 7, 3, 2, 9, 0, 4, 6 };
  int[] d = new int[10] { 9, 4, 7, 2, 8, 0, 5, 1, 3, 4 };
  textBox1.Text = Convert.ToString(b[rnd.Next(10)]) + Convert.ToString(d[rnd.Next(10)]);
}

and so on for 3, 4, 5, and 6 ... digit random numbers.

Hope this assists someone positively.

For Visual Basic, HTML and JScript and RDL Expression, the Window > New Window option mentioned in PaulB's answer is disabled. However an option can be changed in the Registry to enable the menu item.

All other languages do not restrict to a single code window so you can use PaulB's answer without editing the registry.

Enabling New Window in Windows Registry.^{[1] [2]}

1. Go to the following registry key. This example is for Basic (Visual Basic), but the key is also there for HTML, JScript and RDL Expression.

   • 64-bit OS: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\10.0\Languages\Language Services\Basic
   • 32-bit OS: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\10.0\Languages\Language Services\Basic

2. Find the value Single Code Window Only and do one of the following:

   • Set it to 0
   • Rename the value
   • Delete the value (use caution!)

This will enable the "New Window" menu item, but it may still not be visible in the menu.

Adding Menu Item

To actually see the New Window menu item I had to add it back into the menu:

• Tools > Customize... > Commands > Add Command...
• Select 'Menu Bar' the select the 'Window' menu in the dropdown
• Add Command... > Window > New Window > OK

Restoring Registry Value
Copy-paste this to notepad, save as a .reg file and import the file into your registry to restore the initial setting.

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\10.0\Languages\Language Services\Basic]
"Single Code Window Only"=dword:00000001

In HTTP the error occurs.

Set permission for localhost in bellow label(Accept requests from these HTTP referrers (web sites)).

It worked for me.

No, if you are debugging an app without other users use the Build > Build APK(s) menu in Android Studio or execute it in your device/emulator them the debug release apk will install automatically. If you are debugging an app with others use Build > Generate Signed APK... menu. If you want to publish the beta version use the Google Play Store. Your APK(s) will be in app\build\outputs\apk\debug and app\release folders.

I know it's way way overdue, but I have an alternative solution, which is lighter and simpler. Derive a class from System.Windows.Controls.RadioButton and declare two dependency properties RadioValue and RadioBinding. Then in the class code, override OnChecked and set the RadioBinding property value to that of the RadioValue property value. In the other direction, trap changes to the RadioBinding property using a callback, and if the new value is equal to the value of the RadioValue property, set its IsChecked property to true.

Here's the code:

public class MyRadioButton : RadioButton
{
    public object RadioValue
    {
        get { return (object)GetValue(RadioValueProperty); }
        set { SetValue(RadioValueProperty, value); }
    }

    // Using a DependencyProperty as the backing store for RadioValue.
       This enables animation, styling, binding, etc...
    public static readonly DependencyProperty RadioValueProperty =
        DependencyProperty.Register(
            "RadioValue", 
            typeof(object), 
            typeof(MyRadioButton), 
            new UIPropertyMetadata(null));

    public object RadioBinding
    {
        get { return (object)GetValue(RadioBindingProperty); }
        set { SetValue(RadioBindingProperty, value); }
    }

    // Using a DependencyProperty as the backing store for RadioBinding.
       This enables animation, styling, binding, etc...
    public static readonly DependencyProperty RadioBindingProperty =
        DependencyProperty.Register(
            "RadioBinding", 
            typeof(object), 
            typeof(MyRadioButton), 
            new FrameworkPropertyMetadata(
                null, 
                FrameworkPropertyMetadataOptions.BindsTwoWayByDefault, 
                OnRadioBindingChanged));

    private static void OnRadioBindingChanged(
        DependencyObject d,
        DependencyPropertyChangedEventArgs e)
    {
        MyRadioButton rb = (MyRadioButton)d;
        if (rb.RadioValue.Equals(e.NewValue))
            rb.SetCurrentValue(RadioButton.IsCheckedProperty, true);
    }

    protected override void OnChecked(RoutedEventArgs e)
    {
        base.OnChecked(e);
        SetCurrentValue(RadioBindingProperty, RadioValue);
    }
}

XAML usage:

<my:MyRadioButton GroupName="grp1" Content="Value 1"
    RadioValue="val1" RadioBinding="{Binding SelectedValue}"/>
<my:MyRadioButton GroupName="grp1" Content="Value 2"
    RadioValue="val2" RadioBinding="{Binding SelectedValue}"/>
<my:MyRadioButton GroupName="grp1" Content="Value 3"
    RadioValue="val3" RadioBinding="{Binding SelectedValue}"/>
<my:MyRadioButton GroupName="grp1" Content="Value 4"
    RadioValue="val4" RadioBinding="{Binding SelectedValue}"/>

Hope someone finds this useful after all this time :)

Here is how to create a DataFrame where each series is a row.

For a single Series (resulting in a single-row DataFrame):

series = pd.Series([1,2], index=['a','b'])
df = pd.DataFrame([series])

For multiple series with identical indices:

cols = ['a','b']
list_of_series = [pd.Series([1,2],index=cols), pd.Series([3,4],index=cols)]
df = pd.DataFrame(list_of_series, columns=cols)

For multiple series with possibly different indices:

list_of_series = [pd.Series([1,2],index=['a','b']), pd.Series([3,4],index=['a','c'])]
df = pd.concat(list_of_series, axis=1).transpose()

To create a DataFrame where each series is a column, see the answers by others. Alternatively, one can create a DataFrame where each series is a row, as above, and then use df.transpose(). However, the latter approach is inefficient if the columns have different data types.

You gave a condition ID (>79 and < 296) then the answer is:

delete from tab
where id > 79 and id < 296

this is the same as:

delete from tab
where id between 80 and 295

if id is an integer.

All answered:

delete from tab
where id between 79 and 296

this is the same as:

delete from tab
where id => 79 and id <= 296

Mind the difference.

You could just use an even simpler typedef:

typedef char *string;

Then, your malloc would look like a usual malloc:

string s = malloc(maxStringLength);

Assuming that "part within rectangle don't have content color" means that you want different fills within the rectangle; you need to draw a rectangle within your rectangle then with stroke width 0 and the desired fill colour(s).

For example:

DrawView.java

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.view.View;

public class DrawView extends View {
    Paint paint = new Paint();

    public DrawView(Context context) {
        super(context);            
    }

    @Override
    public void onDraw(Canvas canvas) {
        paint.setColor(Color.BLACK);
        paint.setStrokeWidth(3);
        canvas.drawRect(30, 30, 80, 80, paint);
        paint.setStrokeWidth(0);
        paint.setColor(Color.CYAN);
        canvas.drawRect(33, 60, 77, 77, paint );
        paint.setColor(Color.YELLOW);
        canvas.drawRect(33, 33, 77, 60, paint );

    }

}

The activity to start it:

StartDraw.java

import android.app.Activity;
import android.graphics.Color;
import android.os.Bundle;

public class StartDraw extends Activity {
    DrawView drawView;

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

        drawView = new DrawView(this);
        drawView.setBackgroundColor(Color.WHITE);
        setContentView(drawView);

    }
}

...will turn out this way:

Define your Proxy struct separately, outside of Configuration, like this:

type Proxy struct {
    Address string
    Port    string
}

type Configuration struct {
    Val string
    P   Proxy
}

c := &Configuration{
    Val: "test",
    P: Proxy{
        Address: "addr",
        Port:    "80",
    },
}

See http://play.golang.org/p/7PELCVsQIc

You can simply set the value in text box.

First, you get the value like

var getValue = $('#txt_name').val();

After getting a value set in input like

$('#txt_name').val(getValue);

Hope this will help some how in your case, I suffered with the exact same problem, and just used localstorage to share the data between parent window and iframe. So in parent window you can:

localStorage.setItem("url", myUrl);

And in code where iframe source is just get this data from localstorage:

localStorage.getItem('url');

Saved me a lot of time. As far as i can see the only condition is access to the parent page code. Hope this will help someone.

To put a sequence or another numpy array into a numpy array, Just change this line:

kOUT=np.zeros(N+1)

to:

kOUT=np.asarray([None]*(N+1))

Or:

kOUT=np.zeros((N+1), object)

Add jQuery library before your script which uses $ or jQuery so that $ can be identified in scripts.

<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>

If your Manifest.xml has the default android:theme="@style/AppTheme"

Go to res/values/styles.xml and change

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">

to

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">

And the ActionBar is disappeared!

I had the the same problem and I solved it that way:

File currentJavaJarFile = new File(Main.class.getProtectionDomain().getCodeSource().getLocation().getPath());   
String currentJavaJarFilePath = currentJavaJarFile.getAbsolutePath();
String currentRootDirectoryPath = currentJavaJarFilePath.replace(currentJavaJarFile.getName(), "");

I hope I was of help to you.

You can do it like this:

class UsersController < ApplicationController
  ## Exception Handling
  class NotActivated < StandardError
  end

  rescue_from NotActivated, :with => :not_activated

  def not_activated(exception)
    flash[:notice] = "This user is not activated."
    Event.new_event "Exception: #{exception.message}", current_user, request.remote_ip
    redirect_to "/"
  end

  def show
      // Do something that fails..
      raise NotActivated unless @user.is_activated?
  end
end

What you're doing here is creating a class "NotActivated" that will serve as Exception. Using raise, you can throw "NotActivated" as an Exception. rescue_from is the way of catching an Exception with a specified method (not_activated in this case). Quite a long example, but it should show you how it works.

Future answer with CSS4 selectors

New CSS Specs contain an experimental :has pseudo selector that might be able to do this thing.

li:has(a:active) {
  /* ... */
}

The browser support on this is basically non-existent at this time, but it is in consideration on the official specs.

Answer in 2012 that was wrong in 2012 and is even more wrong in 2018

While it is true that CSS cannot ASCEND, it is incorrect that you cannot grab the parent element of another element. Let me reiterate:

Using your HTML example code, you are able to grab the li without specifying li

ul * a {
    property:value;
}

In this example, the ul is the parent of some element and that element is the parent of anchor. The downside of using this method is that if there is a ul with any child element that contains an anchor, it inherits the styles specified.

You may also use the child selector as well since you'll have to specify the parent element anyway.

ul>li a {
    property:value;
}

In this example, the anchor must be a descendant of an li that MUST be a child of ul, meaning it must be within the tree following the ul declaration. This is going to be a bit more specific and will only grab a list item that contains an anchor AND is a child of ul.

SO, to answer your question by code.

ul.menu > li a.active {
    property:value;
}

This should grab the ul with the class of menu, and the child list item that contains only an anchor with the class of active.

Why not just return the worksheet name with address = cell.Worksheet.Name then you can concatenate the address back on like this address = cell.Worksheet.Name & "!" & cell.Address

Put this two lines in style.css In your specified div class.

   display: block;
   margin: auto;

and then try to run it, you will be able to see that .svg aligned in the center.

I tried almost all the options above, none of them worked for my scenario. Finally I was forced to uninstall IIS Express, re-start the machine, and install the same version again from Microsoft.

Anyway thanks for all the suggestions above.

To state the obvious, the cup represents outerScopeVar.

Asynchronous functions be like...

You've nearly got it. The problem is that the Class Under Test (CUT) is not built for unit testing - it has not really been TDD'd.

Think of it like this…

• I need to test a function of a class - let's call it myFunction
• That function makes a call to a function on another class/service/database
• That function also calls another method on the CUT

In the unit test

• Should create a concrete CUT or @Spy on it
• You can @Mock all of the other class/service/database (i.e. external dependencies)
• You could stub the other function called in the CUT but it is not really how unit testing should be done

In order to avoid executing code that you are not strictly testing, you could abstract that code away into something that can be @Mocked.

In this very simple example, a function that creates an object will be difficult to test

public void doSomethingCool(String foo) {
    MyObject obj = new MyObject(foo);

    // can't do much with obj in a unit test unless it is returned
}

But a function that uses a service to get MyObject is easy to test, as we have abstracted the difficult/impossible to test code into something that makes this method testable.

public void doSomethingCool(String foo) {
    MyObject obj = MyObjectService.getMeAnObject(foo);
}

as MyObjectService can be mocked and also verified that .getMeAnObject() is called with the foo variable.

Use ARel

t = Post.arel_table

results = Post.where(
  t[:author].eq("Someone").
  or(t[:title].matches("%something%"))
)

The resulting SQL:

ree-1.8.7-2010.02 > puts Post.where(t[:author].eq("Someone").or(t[:title].matches("%something%"))).to_sql
SELECT     "posts".* FROM       "posts"  WHERE     (("posts"."author" = 'Someone' OR "posts"."title" LIKE '%something%'))

With Swift 5, UIButton has a setTitleColor(_:for:) method. setTitleColor(_:for:) has the following declaration:

Sets the color of the title to use for the specified state.

func setTitleColor(_ color: UIColor?, for state: UIControlState)

The following Playground sample code show how to create a UIbutton in a UIViewController and change it's title color using setTitleColor(_:for:):

import UIKit
import PlaygroundSupport

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        view.backgroundColor = UIColor.white

        // Create button
        let button = UIButton(type: UIButton.ButtonType.system)

        // Set button's attributes
        button.setTitle("Print 0", for: UIControl.State.normal)
        button.setTitleColor(UIColor.orange, for: UIControl.State.normal)

        // Set button's frame
        button.frame.origin = CGPoint(x: 100, y: 100)
        button.sizeToFit()

        // Add action to button
        button.addTarget(self, action: #selector(printZero(_:)), for: UIControl.Event.touchUpInside)

        // Add button to subView
        view.addSubview(button)
    }

    @objc func printZero(_ sender: UIButton) {
        print("0")
    }

}

No, and the fact that you want to seems like a bad idea. Do you really need a default constructor like this?

I'm not very happy with any of the options so I ended up requesting the file in Excel 97 formate. The POI works great for that. Thanks everyone for the help.

You can use KjsCompiler: https://github.com/knyga/kjscompiler Cool dependency managment

http://docs.jquery.com/UI/API/1.8/Dialog

Example for fixed dialog on the left top corner:

$("#dialogId").dialog({
    autoOpen: false,
    modal: false,
    draggable: false,
    height: "auto",
    width: "auto",
    resizable: false,
    position: [0,28],
    create: function (event) { $(event.target).parent().css('position', 'fixed');},
    open: function() {
        //$('#object').load...
    }
});

$("#dialogOpener").click(function() {
    $("#dialogId").dialog("open");
});

For some reason none of these solutions worked for me. I've had the best success using transforms.

transform: translateX(-5.8%) translateY(-5%) scale(0.884);

Did you maybe use some <tab> instead of spaces?

Try remove all the spaces before the code and readd them using <space> characters, just to be sure it's not a <tab>.

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.

In Angular 8, ViewChild always takes 2 param, and second params always has static: true or static: false

You can try like this:

@ViewChild('nameInput', {static: false}) component

Also,the static: false is going to be the default fallback behaviour in Angular 9.

What are static false/true: So as a rule of thumb you can go for the following:

• { static: true } needs to be set when you want to access the ViewChild in ngOnInit.

  { static: false } can only be accessed in ngAfterViewInit. This is also what you want to go for when you have a structural directive (i.e. *ngIf) on your element in your template.

To add to the answers above, while print can only take one parameter, it will allow for concatenation of multiple values, ie:

$count = 5;

print "This is " . $count . " values in " . $count/5 . " parameter";

This is 5 values in 1 parameter

on my C drive I first create a txt file to create a new table. You can use what ever you want in this text file

in this case the text file is called "Bedrijf.txt"

the content:

Print 'START(A) create table'

GO 1

If not EXISTS
(
    SELECT *
    FROM INFORMATION_SCHEMA.TABLES
    WHERE TABLE_NAME = 'Bedrijf'
)
BEGIN
CREATE TABLE [dbo].[Bedrijf] (
[IDBedrijf] [varchar] (38)   NOT NULL ,
[logo] [varbinary] (max) NULL ,
[VolledigeHandelsnaam] [varchar] (100)  NULL 
) ON [PRIMARY]

save it

then I create an other txt file with the name "Bedrijf.bat" and the extension bat. It's content:

OSQL.EXE  -U Username -P Password -S IPaddress -i C:Bedrijf.txt -o C:Bedrijf.out -d myDatabaseName

save it and from explorer double click to execute

The results will be saved in a txt file on your C drive with the name "Bedrijf.out"

it shows

1> 2> 3> START(A) create table

if all goes well

That's it

HTML 5 allows summary tag, details element. That can be used to view or hide (collapse/expand) a section. Link

Following width worked well in HTML5: -

<table >
  <tr>
    <th style="min-width:120px">Month</th>
    <th style="min-width:60px">Savings</th>
  </tr>
  <tr>
    <td>January</td>
    <td>$100</td>
  </tr>
  <tr>
    <td>February</td>
    <td>$80</td>
  </tr>
</table>

Please note that

• TD tag is without CSS style.

java.sql.Timestamp                  
.valueOf(                           // Class-method parses SQL-style formatted date-time strings.
    "2007-11-11 12:13:14"
)                                   // Returns a `Timestamp` object.
.toInstant()                        // Converts from terrible legacy classes to modern *java.time* class.

java.sql.Timestamp.valueOf parses SQL format

If you can use the full four digits for the year, your input string of 2007-11-11 12:13:14 would be in standard SQL format assuming this value is meant to be in UTC time zone.

The java.sql.Timestamp class has a valueOf method to directly parse such strings.

String input = "2007-11-11 12:13:14" ;
java.sql.Timestamp ts = java.sql.Timestamp.valueOf( input ) ;

java.time

In Java 8 and later, the java.time framework makes it easier to verify the results. The j.s.Timestamp class has a nasty habit of implicitly applying your JVM’s current default timestamp when generating a string representation via its toString method. In contrast, the java.time classes by default use the standard ISO 8601 formats.

System.out.println( "Output: " + ts.toInstant().toString() );

best way is using reference, and not using unset (which make another step to clean memory)

$tab = ['two' => [] ];

solution:

$tab['newname'] = & $tab['two'];

you have one original and one reference with new name.

or if you don't want have two names in one value is good make another tab and foreach on reference

foreach($tab as $key=> & $value) {
    if($key=='two') { 
        $newtab["newname"] = & $tab[$key];
     } else {
        $newtab[$key] = & $tab[$key];
     }
}

Iterration is better on keys than clone all array, and cleaning old array if you have long data like 100 rows +++ etc..

Deletion of a topic has been supported since 0.8.2.x version. You have to enable topic deletion (setting delete.topic.enable to true) on all brokers first.

Note: Ever since 1.0.x, the functionality being stable, delete.topic.enable is by default true.

Follow this step by step process for manual deletion of topics

1. Stop Kafka server
2. Delete the topic directory, on each broker (as defined in the logs.dirs and log.dir properties) with rm -rf command
3. Connect to Zookeeper instance: zookeeper-shell.sh host:port
4. From within the Zookeeper instance:
   1. List the topics using: ls /brokers/topics
   2. Remove the topic folder from ZooKeeper using: rmr /brokers/topics/yourtopic
   3. Exit the Zookeeper instance (Ctrl+C)
5. Restart Kafka server
6. Confirm if it was deleted or not by using this command kafka-topics.sh --list --zookeeper host:port

Swift 2 Version

As @Johan Karlsson pointed out... I was doing it wrong. Here's the proper way to send and receive information with NSNotificationCenter.

First, we look at the initializer for postNotificationName:

init(name name: String,
   object object: AnyObject?,
 userInfo userInfo: [NSObject : AnyObject]?)

source

We'll be passing our information using the userInfo param. The [NSObject : AnyObject] type is a hold-over from Objective-C. So, in Swift land, all we need to do is pass in a Swift dictionary that has keys that are derived from NSObject and values which can be AnyObject.

With that knowledge we create a dictionary which we'll pass into the object parameter:

 var userInfo = [String:String]()
 userInfo["UserName"] = "Dan"
 userInfo["Something"] = "Could be any object including a custom Type."

Then we pass the dictionary into our object parameter.

Sender

NSNotificationCenter.defaultCenter()
    .postNotificationName("myCustomId", object: nil, userInfo: userInfo)

Receiver Class

First we need to make sure our class is observing for the notification

override func viewDidLoad() {
    super.viewDidLoad()

    NSNotificationCenter.defaultCenter().addObserver(self, selector: Selector("btnClicked:"), name: "myCustomId", object: nil)   
}
    

Then we can receive our dictionary:

func btnClicked(notification: NSNotification) {
   let userInfo : [String:String!] = notification.userInfo as! [String:String!]
   let name = userInfo["UserName"]
   print(name)
}

Yes, LINQ to Objects supports this with Enumerable.Concat:

var together = first.Concat(second);

NB: Should first or second be null you would receive a ArgumentNullException. To avoid this & treat nulls as you would an empty set, use the null coalescing operator like so:

var together = (first ?? Enumerable.Empty<string>()).Concat(second ?? Enumerable.Empty<string>()); //amending `<string>` to the appropriate type

Make clickable icon to focus inside the text input element.

CSS

.myClass {
    font-size:20px;
    position:absolute; top:10px; left:10px;
}

HTML

<div>
    <label style="position:relative;">
         <i class="myClass fa fa-address-book-o"></i>
         <input class="w3-input" type="text" style="padding-left:40px;">
    </label>
</div>

Just add whichever icon you like inside the <i> tag, from Font Awesome library and enjoy the results.

• What is the most typical/common way of doing this with an object C++ (that doesn't involve overloading the == operator)?
• Is this even the right approach? ie. should I not write functions that take an object as an argument, but rather, write member functions? (But even if so, please answer the original question.)

No, references cannot be null (unless Undefined Behavior has already happened, in which case all bets are already off). Whether you should write a method or non-method depends on other factors.

• Between a function that takes a reference to an object, or a function that takes a C-style pointer to an object, are there reasons to choose one over the other?

If you need to represent "no object", then pass a pointer to the function, and let that pointer be NULL:

int silly_sum(int const* pa=0, int const* pb=0, int const* pc=0) {
  /* Take up to three ints and return the sum of any supplied values.

  Pass null pointers for "not supplied".

  This is NOT an example of good code.
  */
  if (!pa && (pb || pc)) return silly_sum(pb, pc);
  if (!pb && pc) return silly_sum(pa, pc);
  if (pc) return silly_sum(pa, pb) + *pc;
  if (pa && pb) return *pa + *pb;
  if (pa) return *pa;
  if (pb) return *pb;
  return 0;
}

int main() {
  int a = 1, b = 2, c = 3;
  cout << silly_sum(&a, &b, &c) << '\n';
  cout << silly_sum(&a, &b) << '\n';
  cout << silly_sum(&a) << '\n';
  cout << silly_sum(0, &b, &c) << '\n';
  cout << silly_sum(&a, 0, &c) << '\n';
  cout << silly_sum(0, 0, &c) << '\n';
  return 0;
}

If "no object" never needs to be represented, then references work fine. In fact, operator overloads are much simpler because they take overloads.

You can use something like boost::optional.

We apply StandardScalar() on a row basis.

So, for each row in a column (I am assuming that you are working with a Pandas DataFrame):

x_new = (x_original - mean_of_distribution) / std_of_distribution

Few points -

1. It is called Standard Scalar as we are dividing it by the standard deviation of the distribution (distr. of the feature). Similarly, you can guess for MinMaxScalar().

2. The original distribution remains the same after applying StandardScalar(). It is a common misconception that the distribution gets changed to a Normal Distribution. We are just squashing the range into [0, 1].

I had the same problem while installing gensim on windows. Gensim is dependent on scipy and scipy on numpy. Making all three work is real pain. It took me a lot of time to make all there work on same time.

Solution: If you are using windows make sure you install numpy+mkl instead of just numpy. If you have already installed scipy and numpy, uninstall then using "pip uninstall scipy" and "pip uninstall numpy"

Then download numpy-1.13.1+mkl-cp34-cp34m-win32.whl from http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy and install using pip install numpy-1.13.1+mkl-cp34-cp34m-win32.wh Note: in cp34-cp34m 34 represent the version of python you are using, so download the relevant version.

Now download scipy from http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy (appropriate version for your python and system) and install using "pip install scipy-0.19.1-cp34-cp34m-win32.whl"

Your numpy and Scipy both should work now. These binaries by Christoph Gohlke makes it very easy to install python packages on windows. But make sure you download all the dependent packages from there.

A simplified solution, without creating a new Matcher implementation class and using lambda expression:

verify(mockObject).someMockMethod(
        argThat((SomeArgument arg) -> arg.fieldToMatch.equals(expectedFieldValue));

This:

https://github.com/jbtule/cdto#cd-to

It's a small app that you drag into the Finder toolbar, the icon fits in very nicely. It works with Terminal, xterm (under X11), iterm.

if you use nginx

# skip favicon.ico
#
location = /favicon.ico {
    access_log off;
    return 204;
}

The Solution to this problem, tends to differ slightly from case to case. The general way to solve it is to
1.) right-click the bootstrap pill and select inspect or inspect element if firefox
2.) copy the css selector for the rule that changes the color
3.) modify it in your custom css file like so...

.TheCssSelectorYouJustCopied{
    background-color: #ff0000!important;//or any other color
}

Because if you don't make a copy then the indices can still be manipulated elsewhere even if you assign the dataFrame to a different name.

For example:

df2 = df
func1(df2)
func2(df)

func1 can modify df by modifying df2, so to avoid that:

df2 = df.copy()
func1(df2)
func2(df)

The solution that worked for me was: dir > a.txt | type a.txt.

Why dont you show a generated Picture (screenshot) of the PDF?

Official Kotlin Way:

override fun onKeyDown(keyCode: Int, event: KeyEvent?): Boolean {
    // Check if the key event was the Back button and if there's history
    if (keyCode == KeyEvent.KEYCODE_BACK && myWebView.canGoBack()) {
        myWebView.goBack()
        return true
    }
    // If it wasn't the Back key or there's no web page history, bubble up to the default
    // system behavior (probably exit the activity)
    return super.onKeyDown(keyCode, event)
}

https://developer.android.com/guide/webapps/webview.html#NavigatingHistory

Try this: Call this method and pass 3 arguments:

1. WebDriver variable. // assuming driver_variable as driver.
2. The element which you are going to check. Should provide from By method. // ex: By.id("id")
3. Time limit in seconds.

Example: waitForElementPresent(driver, By.id("id"), 10 );

public static WebElement waitForElementPresent(WebDriver driver, final By by, int timeOutInSeconds) {

        WebElement element; 

        try{
            driver.manage().timeouts().implicitlyWait(0, TimeUnit.SECONDS); //nullify implicitlyWait() 

            WebDriverWait wait = new WebDriverWait(driver, timeOutInSeconds); 
            element = wait.until(ExpectedConditions.presenceOfElementLocated(by));

            driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS); //reset implicitlyWait
            return element; //return the element
        } catch (Exception e) {
            e.printStackTrace();
        } 
        return null; 
    }

I find git stash very useful for temporal handling of all 'dirty' states.

string cannot be the parameter to Nullable because string is not a value type. String is a reference type.

string s = null; 

is a very valid statement and there is not need to make it nullable.

private string typeOfContract
    {
      get { return ViewState["typeOfContract"] as string; }
      set { ViewState["typeOfContract"] = value; }
    }

should work because of the as keyword.

You can do it in 1 line, by using Linq

listBox1.Cast<ListItem>().Where(p=>p.Text.Contains("OBJECT")).ToList().ForEach(listBox1.Items.Remove);

In CakePHP 1.2 ..

$db =& ConnectionManager::getDataSource('default');
$db->showLog();

If you want to set the same value on a collection of rows, you can use the update() method combined with any query term to update all rows in one query:

some_list = ModelClass.objects.filter(some condition).values('id')
ModelClass.objects.filter(pk__in=some_list).update(foo=bar)

If you want to update a collection of rows with different values depending on some condition, you can in best case batch the updates according to values. Let's say you have 1000 rows where you want to set a column to one of X values, then you could prepare the batches beforehand and then only run X update-queries (each essentially having the form of the first example above) + the initial SELECT-query.

If every row requires a unique value there is no way to avoid one query per update. Perhaps look into other architectures like CQRS/Event sourcing if you need performance in this latter case.

import csv
with open('input.csv','r') as csvinput:
    with open('output.csv', 'w') as csvoutput:
        writer = csv.writer(csvoutput)

        for row in csv.reader(csvinput):
            if row[0] == "Name":
                writer.writerow(row+["Berry"])
            else:
                writer.writerow(row+[row[0]])

Maybe something like that is what you intended?

Also, csv stands for comma separated values. So, you kind of need commas to separate your values like this I think:

Name,Code
blackberry,1
wineberry,2
rasberry,1
blueberry,1
mulberry,2

I have been looking at this. On populating the drop down anchors, I have given them a class and data attributes, so when needing to do an action you can do:

<li><a class="dropDownListItem" data-name="Fred Smith" href="#">Fred</a></li>

and then in the jQuery doing something like:

$('.dropDownListItem').click(function(e) {
    var name = e.currentTarget;
    console.log(name.getAttribute("data-name"));
});

So if you have dynamically generated list items in your dropdown and need to use the data that isn't just the text value of the item, you can use the data attributes when creating the dropdown listitem and then just give each item with the class the event, rather than referring to the id's of each item and generating a click event.

this may also work.

The first section is called a protocol and yes you can register your own. On Windows (where I'm assuming you're doing this given the C# tag - sorry Mono fans), it's done via the registry.

It's all you need to remember for 99% of cases.

For loading the layout in layout-land folder means you have two separate layouts then you have to make setContentView in onConfigurationChanged method.

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);

    // Checks the orientation of the screen
    if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
        setContentView(R.layout.yourxmlinlayout-land);
    } else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){
        setContentView(R.layout.yourxmlinlayoutfolder);
    }
}

If you have only one layout then no necessary to make setContentView in This method. simply

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
}

Every method, mentioned earlier does looping either internally or externally, so it is not really important how to implement it. Here another example of finding all references of target string

       string [] arr = {"One","Two","Three"};
       var target = "One";
       var results = Array.FindAll(arr, s => s.Equals(target));

The accepted answer works great, but the resize logic ignores the case in which the image is larger than the maximum in only one of the axes (for example, height > maxHeight but width <= maxWidth).

I think the following code takes care of all cases in a more straight-forward and functional way (ignore the typescript type annotations if using plain javascript):

private scaleDownSize(width: number, height: number, maxWidth: number, maxHeight: number): {width: number, height: number} {
    if (width <= maxWidth && height <= maxHeight)
      return { width, height };
    else if (width / maxWidth > height / maxHeight)
      return { width: maxWidth, height: height * maxWidth / width};
    else
      return { width: width * maxHeight / height, height: maxHeight };
  }

One more possible solution: I have a staging server that serves the site and the Cloudfront assets over HTTP. I had my origin set to "Match Viewer" instead of "HTTP Only". I also use the HTTPS Everywhere extension, which redirected all the http://*.cloudfront.net URLs to the https://* version. Since the staging server isn't available over SSL and Cloudfront was matching the viewer, it couldn't find the assets at https://example.com and cached a bunch of 502s instead.

    Model1: 'date',
    Model2: 'pubdate',

And then sorted(chain(Model1.objects.all(), Model2.objects.all()), key=my_key_func)

Some terminals allow to print colored text. Some colors look like if they are "bold". Try:

print ('\033[1;37mciao!')

The sequence '\033[1;37m' makes some terminals to start printing in "bright white" that may look a bit like bolded white. '\033[0;0m' will turn it off.

Let's consider the purpose of the service.

In forward proxy:

Proxy helps user to access server.

In reverse proxy:

Proxy helps server to be accessed by user.

In the latter case, the one who is helped by the proxy is no longer a user, but a server, that's the reason why we call it a reverse proxy.

for me all these didn't work. What worked for me was something really simple:

$("#formID input[type=text]").each(function() {
alert($(this).val());
});

 // Get calendar set to the current date and time
Calendar cal = Calendar.getInstance();

// Set time of calendar to 18:00
cal.set(Calendar.HOUR_OF_DAY, 18);
cal.set(Calendar.MINUTE, 0);
cal.set(Calendar.SECOND, 0);
cal.set(Calendar.MILLISECOND, 0);

// Check if current time is after 18:00 today
boolean afterSix = Calendar.getInstance().after(cal);

if (afterSix) {
    System.out.println("Go home, it's after 6 PM!");
}
else {
    System.out.println("Hello!");
}

Try adding the below code to the class that you want to use

[Serializable()]
public partial class Class
{

(num1>=num2)*num1+(num2>num1)*num2 will return the maximum of two values.

Try this:

jupyter notebook --NotebookApp.iopub_data_rate_limit=1.0e10

Or this:

yourTerminal:prompt> jupyter notebook --NotebookApp.iopub_data_rate_limit=1.0e10 

To get the format you want:

SELECT (substring(CONVERT(VARCHAR,GETDATE(),22),10,8) + ' ' + SUBSTRING(CONVERT(VARCHAR,getdate(),22), 19,2))

In Visual Studio 2015, you can place a breakpoint on the set accessor of an Auto-Implemented Property and the debugger will break when the property is updated

public bool IsUpdated
{
    get;
    set;    //set breakpoint on this line
}

Update

Alternatively; @AbdulRaufMujahid has pointed out in the comments that if the auto implemented property is on a single line, you can position your cursor at the get; or set; and hit F9 and a breakpoint will be placed accordingly. Nice!

public bool IsUpdated { get; set; }

The difference between RMI and RPC is that:

• RMI as the name indicates Remote Method Invoking: it invokes a method or an object. And
• RPC it invokes a function.

A very much simpler and elegant way is to use this:

 import os
 dir_list = os.walk('.').next()[1]
 print dir_list

Run this script in the same folder for which you want folder names.It will give you exactly the immediate folders name only(that too without the full path of the folders).

setInterval returns an id that you can use to cancel the interval with clearInterval()

Off the top of my head:

1. Styles - Obj-C is dynamic, C++ is typically static
2. Although they are both OOP, I'm certain the solutions would be different.
3. Different object model (C++ is restricted by its compile-time type system).

To me, the biggest difference is the model system. Obj-C lets you do messaging and introspection, but C++ has the ever-so-powerful templates.

Each have their strengths.

this make me success!

Just in case someone is working with Eclipse

Windows 8.1 OS | Eclipse Idle Luna

Declare top level variable private String username Eclipse kindly generate a warning on the left of your screen click that warning and couple of suggestions show up, then select generate.

How I do:

# Remove python2
sudo apt purge -y python2.7-minimal

# You already have Python3 but 
# don't care about the version 
sudo ln -s /usr/bin/python3 /usr/bin/python

# Same for pip
sudo apt install -y python3-pip
sudo ln -s /usr/bin/pip3 /usr/bin/pip

# Confirm the new version of Python: 3
python --version

You can use Javascript URLSearchParams.

var url = new URL(window.location.href);
url.searchParams.set('single','');
window.location.href = url.href;

[UPDATE]: If IE support is a need, check this thread:

SCRIPT5009: 'URLSearchParams' is undefined in IE 11

Thanks @john-m to talk about the IE support

You can do this using Input.setSelectionRange, part of the Range API for interacting with text selections and the text cursor:

var searchInput = $('#Search');

// Multiply by 2 to ensure the cursor always ends up at the end;
// Opera sometimes sees a carriage return as 2 characters.
var strLength = searchInput.val().length * 2;

searchInput.focus();
searchInput[0].setSelectionRange(strLength, strLength);

Demo: Fiddle

Angular 4:

/* typescript */
import { Location } from '@angular/common';
// ...

@Component({

export class MyComponent {

  constructor(private location: Location) { } 

  goBack() {
    this.location.back(); // go back to previous location
  }
}

Swift 3 & IBInspectable solution:
Inspired by Ade's solution

First, create an UIView extension:

//
//  UIView-Extension.swift
//  

import Foundation
import UIKit

@IBDesignable
extension UIView {
     // Shadow
     @IBInspectable var shadow: Bool {
          get {
               return layer.shadowOpacity > 0.0
          }
          set {
               if newValue == true {
                    self.addShadow()
               }
          }
     }

     fileprivate func addShadow(shadowColor: CGColor = UIColor.black.cgColor, shadowOffset: CGSize = CGSize(width: 3.0, height: 3.0), shadowOpacity: Float = 0.35, shadowRadius: CGFloat = 5.0) {
          let layer = self.layer
          layer.masksToBounds = false

          layer.shadowColor = shadowColor
          layer.shadowOffset = shadowOffset
          layer.shadowRadius = shadowRadius
          layer.shadowOpacity = shadowOpacity
          layer.shadowPath = UIBezierPath(roundedRect: layer.bounds, cornerRadius: layer.cornerRadius).cgPath

          let backgroundColor = self.backgroundColor?.cgColor
          self.backgroundColor = nil
          layer.backgroundColor =  backgroundColor
     }


     // Corner radius
     @IBInspectable var circle: Bool {
          get {
               return layer.cornerRadius == self.bounds.width*0.5
          }
          set {
               if newValue == true {
                    self.cornerRadius = self.bounds.width*0.5
               }
          }
     }

     @IBInspectable var cornerRadius: CGFloat {
          get {
               return self.layer.cornerRadius
          }

          set {
               self.layer.cornerRadius = newValue
          }
     }


     // Borders
     // Border width
     @IBInspectable
     public var borderWidth: CGFloat {
          set {
               layer.borderWidth = newValue
          }

          get {
               return layer.borderWidth
          }
     }

     // Border color
     @IBInspectable
     public var borderColor: UIColor? {
          set {
               layer.borderColor = newValue?.cgColor
          }

          get {
               if let borderColor = layer.borderColor {
                    return UIColor(cgColor: borderColor)
               }
               return nil
          }
     }
}

Then, simply select your UIView in interface builder setting shadow ON and corner radius, like below:

The result!

=Sumifs(B:B,A:A,">=1/1/2013",A:A,"<=1/31/2013")

The beauty of this formula is you can add more data to columns A and B and it will just recalculate.

Understanding Requests Body

When receiving a POST or PUT request, the request body might be important to your application. Getting at the body data is a little more involved than accessing request headers. The request object that's passed in to a handler implements the ReadableStream interface. This stream can be listened to or piped elsewhere just like any other stream. We can grab the data right out of the stream by listening to the stream's 'data' and 'end' events.

The chunk emitted in each 'data' event is a Buffer. If you know it's going to be string data, the best thing to do is collect the data in an array, then at the 'end', concatenate and stringify it.

let body = [];
request.on('data', (chunk) => {
  body.push(chunk);
}).on('end', () => {
  body = Buffer.concat(body).toString();
  // at this point, `body` has the entire request body stored in it as a string
});

Understanding body-parser

As per its documentation

Parse incoming request bodies in a middleware before your handlers, available under the req.body property.

As you saw in the first example, we had to parse the incoming request stream manually to extract the body. This becomes a tad tedious when there are multiple form data of different types. So we use the body-parser package which does all this task under the hood.

It provides four modules to parse different types of data

• JSON body parser
• Raw body parser
• Text body parser
• URL-encoded form body parser

After having the raw content body-parser will use one of the above strategies(depending on middleware you decided to use) to parse the data. You can read more about them by reading their documentation.

After setting the req.body to the parsed body, body-parser will invoke next() to call the next middleware down the stack, which can then access the request data without having to think about how to unzip and parse it.

Values not necessarily have to be unique so you have to do a lookup. You can do something like this:

var myKey = types.FirstOrDefault(x => x.Value == "one").Key;

If values are unique and are inserted less frequently than read, then create an inverse dictionary where values are keys and keys are values.

This works:

''.join(('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e'))

It will produce:

'abcdgxre'

You can also use a delimiter like a comma to produce:

'a,b,c,d,g,x,r,e'

By using:

','.join(('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e'))

If you trust the host, either add the valid certificate, specify --no-check-certificate or add:

check_certificate = off

into your ~/.wgetrc.

In some rare cases, your system time could be out-of-sync therefore invalidating the certificates.

For a lambda-avoiding method, first define your own function:

def MyFn(a):
    return a[1]

then:

sorted([('abc', 121),('abc', 231),('abc', 148), ('abc',221)], key=MyFn)

You can't... an array's size is always fixed in Java. Typically instead of using an array, you'd use an implementation of List<T> here - usually ArrayList<T>, but with plenty of other alternatives available.

You can create an array from the list as a final step, of course - or just change the signature of the method to return a List<T> to start with.

This is solution without jquery.

Add Calendar and TextBox in WebForm -> Source of WebForm has this:

<asp:Calendar ID="Calendar1" runat="server" OnSelectionChanged="DateChange">
</asp:Calendar>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

Create methods in cs file of WebForm:

protected void Page_Load(object sender, EventArgs e)
    {
        TextBox1.Text = DateTime.Today.ToShortDateString()+'.';
    }

    protected void DateChange(object sender, EventArgs e)
    {
        TextBox1.Text = Calendar1.SelectedDate.ToShortDateString() + '.';
    }

Method DateChange is connected with Calendar event SelectionChanged. It looks like this: DatePicker Image

In Android Studio (mine is 2.3.1) go to File - Project Structure:

Had similar problems just now and these are two separate instances and solutions that worked for me:

Case 1. Basically, had a space after the last command within my newline-separated for-loop, eg. (imagining that | here represents the carat in a text editor showing where you are writing), this is what I saw when clicking around the end of the line of the last command in the loop:

for f in $pathToFiles
do
   $stuff |
done

Notice the space before before the carat (so far as I know, this is something cat has no option do display visually (one way you could test is with something like od -bc yourscript.sh)). Changing the code to

for f in $pathToFiles
do
   $stuff| <--- notice the carat shows no ending space before the newline
done

fixed the problem.

Case 2. Was using a pseudo try-catch block for the for-loop (see https://stackoverflow.com/a/22010339/8236733) like

{
for f in $pathToFiles
do
   { $stuff } || { echo "Failed to complete stuff"; exit 255; }
done
} || { echo "Failed to complete loop"; exit 255; }

and apparently bash did not like the nested {}s. Changing to

{
for f in $pathToFiles
do
   $stuff
done
} || { echo "Failed to complete loop"; exit 255; }

fixed the problem in this case. If anyone can further explain either of these cases, please let me know more about them in the comments.

To complement answers above...

If you are using EF, adorn the property with Data Annotation [Timestamp], then go to the overrided OnModelCreating, inside your context class, and add this Fluent API code:

modelBuilder.Entity<YourEntity>()
                .Property(b => b.Timestamp)
                .ValueGeneratedOnAddOrUpdate()
                .IsConcurrencyToken()
                .ForSqliteHasDefaultValueSql("CURRENT_TIMESTAMP");

It will make a default value to every data that will be insert into this table.

Better way to do this use custom dialog and customize according your needs here is custom dialog example.....

public class CustomDialogUI {
Dialog dialog;
Vibrator vib;
RelativeLayout rl;

@SuppressWarnings("static-access")
public void dialog(final Context context, String title, String message,
        final Runnable task) {
    dialog = new Dialog(context);
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.setContentView(R.layout.custom);
    dialog.setCancelable(false);
    TextView m = (TextView) dialog.findViewById(R.id.message);
    TextView t = (TextView) dialog.findViewById(R.id.title);
    final Button n = (Button) dialog.findViewById(R.id.button2);
    final Button p = (Button) dialog.findViewById(R.id.next_button);
    rl = (RelativeLayout) dialog.findViewById(R.id.rlmain);
    t.setText(bold(title));
    m.setText(message);
    dialog.show();
    n.setText(bold("Close"));
    p.setText(bold("Ok"));
    // color(context,rl);
    vib = (Vibrator) context.getSystemService(context.VIBRATOR_SERVICE);
    n.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View arg0) {
            vib.vibrate(15);
            dialog.dismiss();
        }
    });
    p.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View arg0) {
            vib.vibrate(20);
            dialog.dismiss();
            task.run();
        }
    });
}
 //customize text style bold italic....
public SpannableString bold(String s) {
    SpannableString spanString = new SpannableString(s);
    spanString.setSpan(new StyleSpan(Typeface.BOLD), 0,
            spanString.length(), 0);
    spanString.setSpan(new UnderlineSpan(), 0, spanString.length(), 0);
    // spanString.setSpan(new StyleSpan(Typeface.ITALIC), 0,
    // spanString.length(), 0);
    return spanString;
}

}

CSS-only

for Chrome, Firefox, Edge (and other evergreen browsers)

Simply position: sticky; top: 0; your th elements:

/* Fix table head */
.tableFixHead    { overflow-y: auto; height: 100px; }
.tableFixHead th { position: sticky; top: 0; }

/* Just common table stuff. */
table  { border-collapse: collapse; width: 100%; }
th, td { padding: 8px 16px; }
th     { background:#eee; }

<div class="tableFixHead">
  <table>
    <thead>
      <tr><th>TH 1</th><th>TH 2</th></tr>
    </thead>
    <tbody>
      <tr><td>A1</td><td>A2</td></tr>
      <tr><td>B1</td><td>B2</td></tr>
      <tr><td>C1</td><td>C2</td></tr>
      <tr><td>D1</td><td>D2</td></tr>
      <tr><td>E1</td><td>E2</td></tr>
    </tbody>
  </table>
</div>

PS: if you need borders for TH elements th {box-shadow: 1px 1px 0 #000; border-top: 0;} will help (since the default borders are not painted correctly on scroll).

For a variant of the above that uses just a bit of JS in order to accommodate for IE11 see this answer Table fixed header and scrollable body

To make the browser downloads a file you need to make the request like that:

 function downloadFile(urlToSend) {
     var req = new XMLHttpRequest();
     req.open("GET", urlToSend, true);
     req.responseType = "blob";
     req.onload = function (event) {
         var blob = req.response;
         var fileName = req.getResponseHeader("fileName") //if you have the fileName header available
         var link=document.createElement('a');
         link.href=window.URL.createObjectURL(blob);
         link.download=fileName;
         link.click();
     };

     req.send();
 }

Both methods do the same functionally - they compare values.
As is written on MSDN:

• About String.Equals method - Determines whether this instance and another specified String object have the same value. (http://msdn.microsoft.com/en-us/library/858x0yyx.aspx)
• About == - Although string is a reference type, the equality operators (== and !=) are defined to compare the values of string objects, not references. This makes testing for string equality more intuitive. (http://msdn.microsoft.com/en-en/library/362314fe.aspx)

But if one of your string instances is null, these methods are working differently:

string x = null;
string y = "qq";
if (x == y) // returns false
    MessageBox.Show("true");
else
    MessageBox.Show("false");

if (x.Equals(y)) // returns System.NullReferenceException: Object reference not set to an instance of an object. - because x is null !!!
    MessageBox.Show("true");
else
    MessageBox.Show("false");

I have similar situation. In my case, it doesn't have a parent with position:relative. Just paste my solution here for those that might need.

position: fixed;
left: 0;
right: 0;

It can be useful if mixed new property add in runtime:

data = { ...data, newPropery: value}

However, spread operator use shallow copy but here we assign data to itself so should lose nothing

As of 2019 there is a subcommand: vagrant box repackage

vagrant box repackage --help 
Usage: vagrant box repackage <name> <provider> <version>
    -h, --help                       Print this help

You can find name provider and version by running vagrant box list

vagrant box list
macinbox (virtualbox, 10.14.5)

The ouput of vagrant box repackage is a file called package.box which is basically a tgz file which the content can be listed as below:

tar tzf package.box
./metadata.json
./box.ovf
./Vagrantfile
./box-disk001.vmdk

Thanks Paul-g for your advise. For my part it was a bit different.

I installed Boost by following the Step 5 of : https://www.boost.org/doc/libs/1_59_0/more/getting_started/unix-variants.html

And then I add PATH directory in the "FindBoos.cmake", located in /usr/local/share/cmake-3.5/Modules :

SET (BOOST_ROOT "../boost_1_60_0")
SET (BOOST_INCLUDEDIR "../boost_1_60_0/boost")
SET (BOOST_LIBRARYDIR "../boost_1_60_0/libs")

SET (BOOST_MIN_VERSION "1.55.0")
set (Boost_NO_BOOST_CMAKE ON)

In addition to the other two answers, I think the indentations are also incorrect in the last two conditions. The conditions are that one name is longer than the other and they need to start with 'elif' and with no indentations. If you put it within the first condition (by giving it four indentations from the margin), it ends up being contradictory because the lengths of the names cannot be equal and different at the same time.

    else:
        print ("The names are different, but are the same length")
elif len(name1) > len(name2):
    print ("{0} is longer than {1}".format(name1, name2))

You can delete the folder itself, as well as all its contents, using shutil.rmtree:

import shutil
shutil.rmtree('/path/to/folder')

shutil.rmtree(path, ignore_errors=False, onerror=None)

Delete an entire directory tree; path must point to a directory (but not a symbolic link to a directory). If ignore_errors is true, errors resulting from failed removals will be ignored; if false or omitted, such errors are handled by calling a handler specified by onerror or, if that is omitted, they raise an exception.

You need to put that code into the constructor of your class:

private Reminders reminder = new Reminders();
private dynamic defaultReminder;

public YourClass()
{
    defaultReminder = reminder.TimeSpanText[TimeSpan.FromMinutes(15)];
}

The reason is that you can't use one instance variable to initialize another one using a field initializer.

Actually you can do it pretty simple, since the list have a ForEach method and since you can pass in Console.WriteLine as a method group. The compiler will then use an implicit conversion to convert the method group to, in this case, an Action<int> and pick the most specific method from the group, in this case Console.WriteLine(int):

  var list = new List<int>(Enumerable.Range(0, 50));

  list.ForEach(Console.WriteLine);

Works with strings too =)

To be utterly pedantic (and I'm not suggesting a change to your answer - just commenting for the sake of interest) Console.WriteLine is a method group. The compiler then uses an implicit conversion from the method group to Action<int>, picking the most specific method (Console.WriteLine(int) in this case).

@media screen and (max-width : 760px) (for tablets and phones) and use with this: <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">

You could use the toJSON() JavaScript method, it converts a JavaScript DateTime to what C# can recognise as a DateTime.

The JavaScript code looks like this

var date = new Date();
date.toJSON(); // this is the JavaScript date as a c# DateTime

Note: The result will be in UTC time

Please find code for respected region.

ViewBag.hdnFlag= Session["hdnFlag"];

JavaScript

var hdnFlagVal = $("#hdnFlag").val();

Just to clarify, be aware bracket placement is important!

These can be added to any HTML tags... span, div, table, p, tr, td etc.

AngularJS

ng-if="check1 && !check2" -- AND NOT
ng-if="check1 || check2" -- OR
ng-if="(check1 || check2) && check3" -- AND/OR - Make sure to use brackets

Angular2+

*ngIf="check1 && !check2" -- AND NOT
*ngIf="check1 || check2" -- OR
*ngIf="(check1 || check2) && check3" -- AND/OR - Make sure to use brackets

It's best practice not to do calculations directly within ngIfs, so assign the variables within your component, and do any logic there.

boolean check1 = Your conditional check here...

For those of us that learn by example...

Write text to a file like this:

IO.write('/tmp/msg.txt', 'hi')

BONUS INFO ...

Read it back like this

IO.read('/tmp/msg.txt')

Frequently, I want to read a file into my clipboard ***

Clipboard.copy IO.read('/tmp/msg.txt')

And other times, I want to write what's in my clipboard to a file ***

IO.write('/tmp/msg.txt', Clipboard.paste)

*** Assumes you have the clipboard gem installed

See: https://rubygems.org/gems/clipboard

Using Kotlin you can do something like:

import android.content.Context
import android.support.v4.content.ContextCompat
import android.support.v7.widget.CardView
import android.widget.*

import android.widget.LinearLayout

class RespondTo : CardView {
    constructor(context: Context) : super(context) {
        init(context)
    }

    private fun init(context: Context) {


        val parent = LinearLayout(context)

        parent.apply {
            layoutParams = LinearLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT,
                    FrameLayout.LayoutParams.WRAP_CONTENT, 1.0f).apply {
                orientation = LinearLayout.HORIZONTAL

                addView(EditText(context).apply {
                    id = generateViewId()
                    layoutParams = LinearLayout.LayoutParams(0,
                            LinearLayout.LayoutParams.WRAP_CONTENT, 0.9f).apply {
                    }
                })
                addView(ImageButton(context).apply({
                    layoutParams = LinearLayout.LayoutParams(0,
                            LinearLayout.LayoutParams.WRAP_CONTENT, 0.1f)
                    background = null
                    setImageDrawable(ContextCompat.getDrawable(context, R.drawable.ic_save_black_24px))
                    id = generateViewId()
                    layoutParams = RelativeLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,
                            LinearLayout.LayoutParams.WRAP_CONTENT).apply {
                        addRule(RelativeLayout.ALIGN_PARENT_RIGHT)
                        // addRule(RelativeLayout.LEFT_OF, myImageButton.id)
