Programs & Examples On #Countif

One solution is doing the sum:

=SUM(COUNTIFS(A1:A196,{"yes","no"},B1:B196,"agree"))

or know its not the countifs but the sumproduct will do it in one line:

=SUMPRODUCT(((A1:A196={"yes","no"})*(j1:j196="agree")))

Table is the obvious choice, but it returns an object of class table which takes a few annoying steps to transform back into a data.frame So, if you're OK using dplyr, you use the command tally:

    library(dplyr)
    df = data.frame(sex=sample(c("M", "F"), 100000, replace=T), occupation=sample(c('Analyst', 'Student'), 100000, replace=T)
    df %>% group_by_all() %>% tally()


# A tibble: 4 x 3
# Groups:   sex [2]
  sex   occupation `n()`
  <fct> <fct>      <int>
1 F     Analyst    25105
2 F     Student    24933
3 M     Analyst    24769
4 M     Student    25193

I am trying to avoid using VBA. But if has to be, then it has to be:)

There is quite simple UDF for you:

Function myCountIf(rng As Range, criteria) As Long
    Dim ws As Worksheet

    For Each ws In ThisWorkbook.Worksheets
        myCountIf = myCountIf + WorksheetFunction.CountIf(ws.Range(rng.Address), criteria)
    Next ws
End Function

and call it like this: =myCountIf(I:I,A13)

P.S. if you'd like to exclude some sheets, you can add If statement:

Function myCountIf(rng As Range, criteria) As Long
    Dim ws As Worksheet

    For Each ws In ThisWorkbook.Worksheets
        If ws.name <> "Sheet1" And ws.name <> "Sheet2" Then
            myCountIf = myCountIf + WorksheetFunction.CountIf(ws.Range(rng.Address), criteria)
        End If
    Next ws
End Function

UPD:

I have four "reference" sheets that I need to exclude from being scanned/searched. They are currently the last four in the workbook

Function myCountIf(rng As Range, criteria) As Long
    Dim i As Integer

    For i = 1 To ThisWorkbook.Worksheets.Count - 4
        myCountIf = myCountIf + WorksheetFunction.CountIf(ThisWorkbook.Worksheets(i).Range(rng.Address), criteria)
    Next i
End Function

I usually use numpy sum over the logical condition column:

>>> import numpy as np
>>> import pandas as pd
>>> df = pd.DataFrame({'Age' : [20,24,18,5,78]})
>>> np.sum(df['Age'] > 20)
2

This seems to me slightly shorter than the solution presented above

With the Dynamic Array formulas(as of this posting only available to Office 365 Insiders):

=COUNTA(UNIQUE(A:A))

You should use

=COUNTIF(A2:A51, "*iPad*")/COUNTA(A2:A51)

Additionally, if you wanted to count more than one element, like iPads OR Kindles, you would use

=SUM(COUNTIF(A2:A51, {"*iPad*", "*kindle*"}))/COUNTA(A2:A51)

in the numerator.

Example-

For cells containing the values between 21-31, the formula is:

=COUNTIF(M$7:M$83,">21")-COUNTIF(M$7:M$83,">31")

Use a pivot table. You can manually refresh a pivot table's data source by right-clicking on it and clicking refresh. Otherwise you can set up a worksheet_change macro - or just a refresh button. Pivot Table tutorial is here: http://chandoo.org/wp/2009/08/19/excel-pivot-tables-tutorial/

1) Create a Month column from your Date column (e.g. =TEXT(B2,"MMM") )

2) Create a Year column from your Date column (e.g. =TEXT(B2,"YYYY") )

3) Add a Count column, with "1" for each value

4) Create a Pivot table with the fields, Count, Month and Year 5) Drag the Year and Month fields into Row Labels. Ensure that Year is above month so your Pivot table first groups by year, then by month 6) Drag the Count field into Values to create a Count of Count

There are better tutorials I'm sure just google/bing "pivot table tutorial".

This is trivial when you use SUMPRODUCT. Por ejemplo:

=SUMPRODUCT((worksheet2!A:A=A3)*1)

You could put the above formula in cell B3, where A3 is the name you want to find in worksheet2.

This assumes that the column of potential date values is in column A. You could do something like this in an adjacent column:

Make a nested formula that converts the "date" to its numeric value if it's valid, or an error value to zero if it's not.
Then it converts the valid numeric values to 1's and leaves the zeroes as they are.
Then sum the new column to get the total number of valid dates.

=IF(IFERROR(DATEVALUE(A1),0)>0,1,0)

Guys Its very interesting to know that many of us face the problem of replication of lookup value while using the Vlookup/Index with Match or Hlookup.... If we have duplicate value in a cell we all know, Vlookup will pick up against the first item would be matching in loopkup array....So here is solution for you all...

e.g.

in Column A we have field called company....

Column A                             Column B            Column C

Company_Name                         Value        
Monster                              25000                              
Naukri                               30000  
WNS                                  80000  
American Express                     40000  
Bank of America                      50000  
Alcatel Lucent                       35000  
Google                               75000  
Microsoft                            60000  
Monster                              35000  
Bank of America                      15000 

Now if you lookup the above dataset, you would see the duplicity is in Company Name at Row No# 10 & 11. So if you put the vlookup, the data will be picking up which comes first..But if you use the below formula, you can make your lookup value Unique and can pick any data easily without having any dispute or facing any problem

Put the formula in C2.........A2&"_"&COUNTIF(A2:$A$2,A2)..........Result will be Monster_1 for first line item and for row no 10 & 11.....Monster_2, Bank of America_2 respectively....Here you go now you have the unique value so now you can pick any data easily now..

You can pass "<>" (including the quotes) as the parameter for criteria. This basically says, as long as its not empty/blank, count it. I believe this is what you want.

=COUNTIF(A1:A10, "<>") 

Otherwise you can use CountA as Scott suggests

The Error is here

lastrow = wsPOR.Range("A" & Rows.Count).End(xlUp).Row + 1

wsPOR is a workbook and not a worksheet. If you are working with "Sheet1" of that workbook then try this

lastrow = wsPOR.Sheets("Sheet1").Range("A" & _
          wsPOR.Sheets("Sheet1").Rows.Count).End(xlUp).Row + 1

Similarly

wsPOR.Range("A2:G" & lastrow).Select

should be

wsPOR.Sheets("Sheet1").Range("A2:G" & lastrow).Select

If multiple criteria use countifs

=countifs(A1:A10,">""",B1:B10,">""")

The " >"" " looks at the greater than being empty. This formula looks for two criteria and neither column can be empty on the same row for it to count. If just counting one column do this with the one criteria (i.e. Use everything before B1:B10 not including the comma)

I had to use COUNTIF() in my case as part of my SELECT columns AND to mimic a % of the number of times each item appeared in my results.

So I used this...

SELECT COL1, COL2, ... ETC
       (1 / SELECT a.vcount 
            FROM (SELECT vm2.visit_id, count(*) AS vcount 
                  FROM dbo.visitmanifests AS vm2 
                  WHERE vm2.inactive = 0 AND vm2.visit_id = vm.Visit_ID 
                  GROUP BY vm2.visit_id) AS a)) AS [No of Visits],
       COL xyz
FROM etc etc

Of course you will need to format the result according to your display requirements.

Excel has no way of gathering that attribute with it's built-in functions. If you're willing to use some VB, all your color-related questions are answered here:

http://www.cpearson.com/excel/colors.aspx

Example form the site:

The SumColor function is a color-based analog of both the SUM and SUMIF function. It allows you to specify separate ranges for the range whose color indexes are to be examined and the range of cells whose values are to be summed. If these two ranges are the same, the function sums the cells whose color matches the specified value. For example, the following formula sums the values in B11:B17 whose fill color is red.

=SUMCOLOR(B11:B17,B11:B17,3,FALSE)

This doesn't seem to work in Mac Excel 2016. After a bit of digging, it looks like the key combination for entering the array formula has changed from ?+RETURN to CTRL+SHIFT+RETURN.

where 0 is initial value

Array.reduce((currentValue, value) => currentValue +value,0)

or

Array.reduce((currentValue, value) =>{ return currentValue +value},0)

or

[1,3,4].reduce(function(currentValue, value) { return currentValue + value},0)

What about

str1.localeCompare(str2)

hope you are doing well. you can use my code to crop image.you just have to make a class and use this class into your XMl and java classes. Crop image. you can crop your selected image into circle and square into many of option. hope fully it will works for you.because this is totally manageable for you and you can change it according to you.

enjoy your work :)

If you use the moment js library it can easily be done like this -

jQuery.validator.addMethod("validDate", function(value, element) {
        return this.optional(element) || moment(value,"DD/MM/YYYY").isValid();
    }, "Please enter a valid date in the format DD/MM/YYYY");

Looks like the initial problem is with the auto-config.

If you don't need the datasource, simply remove it from the auto-config process:

@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})

const polarToCartesian = (centerX, centerY, radius, angleInDegrees) => {
    const angleInRadians = (angleInDegrees - 90) * Math.PI / 180.0;

    return {
        x: centerX + (radius * Math.cos(angleInRadians)),
        y: centerY + (radius * Math.sin(angleInRadians))
    };

const describeSlice = (x, y, radius, startAngle, endAngle) => {

    const start = polarToCartesian(x, y, radius, endAngle);
    const end = polarToCartesian(x, y, radius, startAngle);

    const d = [
        "M", 0, 0, start.x, start.y,
        "A", radius, radius, 0, largeArcFlag, 0, end.x, end.y

const path = (degrees = 90, radius = 10) => {
    return describeSlice(0, 0, radius, 0, degrees) + 'Z';

Use this in web.config:

<sessionState 

  timeout="20" 
/>

Try calling it like: obj.some_function( '1', 2, '3', g="foo", h="bar" ). After the required positional arguments, you can specify specific optional arguments by name.

How are you opening the rendered Markdown?

If you host it over HTTP, i.e. you access it via http:// or https://, most modern browsers will refuse to open local links, e.g. with file://. This is a security feature:

For security purposes, Mozilla applications block links to local files (and directories) from remote files. This includes linking to files on your hard drive, on mapped network drives, and accessible via Uniform Naming Convention (UNC) paths. This prevents a number of unpleasant possibilities, including:

• Allowing sites to detect your operating system by checking default installation paths
• Allowing sites to exploit system vulnerabilities (e.g., C:\con\con in Windows 95/98)
• Allowing sites to detect browser preferences or read sensitive data

There are some workarounds listed on that page, but my recommendation is to avoid doing this if you can.

                    }
                }
            }
        }
    }
}

Example usage:

    Promise.Deferred deferred = default(Promise.Deferred);
    Promise promise = default(Promise);

    int invokedCount = 0;

            promise = deferred.Promise;
        },
        // Teardown

1. According to composer's manual:

   require-dev (root-only)

   Lists packages required for developing this package, or running tests, etc. The dev requirements of the root package are installed by default. Both install or update support the --no-dev option that prevents dev dependencies from being installed.

   So running composer install will also download the development dependencies.

2. The reason is actually quite simple. When contributing to a specific library you may want to run test suites or other develop tools (e.g. symfony). But if you install this library to a project, those development dependencies may not be required: not every project requires a test runner.

This would be my solution:

_x000D_
_x000D_
    // For time zone:_x000D_
    const timeZone = /\((.*)\)/.exec(new Date().toString())[1];_x000D_
    _x000D_
    // Offset hours:_x000D_
    const offsetHours = new Date().getTimezoneOffset() / 60;_x000D_
    _x000D_
    console.log(`${timeZone}, ${offsetHours}hrs`);
_x000D_
_x000D_
_x000D_

// Get the <video> element with id="myVideo"
var vid = document.getElementById("myVideo");

// Assign an ontimeupdate event to the <video> element, and execute a function if the current playback position has changed
vid.ontimeupdate = function() {myFunction()};

function myFunction() {
// Display the current position of the video in a <p> element with id="demo"
    document.getElementById("demo").innerHTML = vid.currentTime;
}

One way to do this is to use String.Substring together with String.IndexOf:

int index = str.IndexOf('-');
string sub;
if (index >= 0)
{
    sub = str.Substring(0, index);
}
else
{
    sub = ... // handle strings without the dash
}

Starting at position 0, return all text up to, but not including, the dash.

I think you are asking for something like the code below:

public interface A
{
    void foo() 
        throws AException;
}

public class B
    implements A
{
    @Overrides 
    public void foo()
        throws AException,
               BException
    {
    }
}

This will not work unless BException is a subclass of AException. When you override a method you must conform to the signature that the parent provides, and exceptions are part of the signature.

The solution is to declare the the interface also throws a BException.

The reason for this is you do not want code like:

public class Main
{
    public static void main(final String[] argv)
    {
        A a;

        a = new B();

        try
        {
            a.foo();
        }
        catch(final AException ex)
        {
        }
        // compiler will not let you write a catch BException if the A interface
        // doesn't say that it is thrown.
    }
}

What would happen if B::foo threw a BException? The program would have to exit as there could be no catch for it. To avoid situations like this child classes cannot alter the types of exceptions thrown (except that they can remove exceptions from the list).

In addition to existing answers it is often desired to format the REST output (typically JSON and XML lacks indentation). Try this:

$ curl https://api.twitter.com/1/help/configuration.xml  | xmllint --format -
$ curl https://api.twitter.com/1/help/configuration.json | python -mjson.tool

Tested on Ubuntu 11.0.4/11.10.

Another issue is the desired content type. Twitter uses .xml/.json extension, but more idiomatic REST would require Accept header:

$ curl -H "Accept: application/json"

Refer to dirkgently's and anon's answers, you can call the front function instead of begin function, so you do not have to write the *, but only the &.

Code Example:

vector<myObject> vec; //You have a vector of your objects
myObject first = vec.front(); //returns reference, not iterator, to the first object in the vector so you had only to write the data type in the generic of your vector, i.e. myObject, and not all the iterator stuff and the vector again and :: of course
myObject* pointer_to_first_object = &first; //* between & and first is not there anymore, first is already the first object, not iterator to it.

sumr is implemented in terms of foldRight:

 final def sumr(implicit A: Monoid[A]): A = F.foldRight(self, A.zero)(A.append) 

foldRight is not always tail recursive, so you can overflow the stack if the collection is too long. See Why foldRight and reduceRight are NOT tail recursive? for some more discussion of when this is or isn't true.

If you want to use SVG files as React components to perform customizations and do not use create-react-app, do the following:

1. Install the Webpack loader called svgr

yarn add --dev @svgr/webpack

2. Update your webpack.config.js

  ...
  module: {
    rules: [
      ...
      // SVG loader
      {
        test: /\.svg$/,
        use: ['@svgr/webpack'],
      }
    ],
  },
  ...

3. Import SVG files as React component

import SomeImage from 'path/to/image.svg'

...

<SomeImage width={100} height={50} fill="pink" stroke="#0066ff" />

I believe this snippet will also be helpful in a situation where the dates comparison spans more than two entries.

static final int COMPARE_EARLIEST = 0;

static final int COMPARE_MOST_RECENT = 1;


public LocalDate getTargetDate(List<LocalDate> datesList, int comparatorType) { 
   LocalDate refDate = null;
   switch(comparatorType)
   {
       case COMPARE_EARLIEST:         
       //returns the most earliest of the date entries
          refDate = (LocalDate) datesList.stream().min(Comparator.comparing(item -> 
                      item.toDateTimeAtCurrentTime())).get();
          break;

       case COMPARE_MOST_RECENT:
          //returns the most recent of the date entries 
          refDate = (LocalDate) datesList.stream().max(Comparator.comparing(item -> 
                    item.toDateTimeAtCurrentTime())).get();
          break;
   }

   return refDate;
}

Most of the time after the installation of Eclipse eclipse.ini is changed. If you change the jdk in eclipse.ini then eclipse will use this jdk by default.

Let's say you install a new version of Eclipse and you have forgotten to change the eclipse.ini related to the jdk. Then Eclipse finds a jdk for you. Let's say it is java 1.6 that was automatically discovered (you did nothing).

If you use maven (M2E) and you reference a 1.7 jdk then you will see the frustrating message. But normally it is not displayed because you configure the correct jdk in eclipse.ini.

That was my case. I made reference into the pom to a jdk that was not configured into Eclipse.

In the screenshot you can see that 1.7 is configured and seen by Eclipse. In this case, you should make reference into the pom to a jre that is compatible with 1.7! If not -> frustrating message!

Updates an old config with new/changed/removed options.

Depends on how you're doing it. Pure javascript:

var div = document.createElement('div');
div.innerHTML = "my <b>new</b> skill - <large>DOM maniuplation!</large>";
// set style
div.style.color = 'red';
// better to use CSS though - just set class
div.setAttribute('class', 'myclass'); // and make sure myclass has some styles in css
document.body.appendChild(div);

Doing the same using jquery is embarrassingly easy:

$('body')
.append('my DOM manupulation skills dont seem like a big deal when using jquery')
.css('color', 'red').addClass('myclass');

Cheers!

A Java constructor has the same name as the name of the class to which it belongs.

Constructor’s syntax does not include a return type, since constructors never return a value.

Constructor is always called when object is created. example:- Default constructor

class Student3{  
    int id;  
    String name;  
    void display(){System.out.println(id+" "+name);}  
    public static void main(String args[]){  
        Student3 s1=new Student3();  
        Student3 s2=new Student3();  
        s1.display();  
        s2.display();  
    }  
} 

Output:

0 null
0 null

Explanation: In the above class,you are not creating any constructor so compiler provides you a default constructor.Here 0 and null values are provided by default constructor.

Example of parameterized constructor

In this example, we have created the constructor of Student class that have two parameters. We can have any number of parameters in the constructor.

class Student4{  
    int id;  
    String name;  
    Student4(int i,String n){  
        id = i;  
        name = n;  
    }  
    void display(){System.out.println(id+" "+name);}  
    public static void main(String args[]){  
        Student4 s1 = new Student4(111,"Karan");  
        Student4 s2 = new Student4(222,"Aryan");  
        s1.display();  
        s2.display();  
    }  
}  

Output:

111 Karan
222 Aryan

February 2020 Update:

The accepted answer is deprecated again in 28 (Android P), but its replacement method only works on 23 (Android M). To support older devices, I wrote a helper function in .

How to use:

int type = getConnectionType(getApplicationContext());

It returns an int, you can change it to enum in your code:

0: No Internet available (maybe on airplane mode, or in the process of joining an wi-fi).

1: Cellular (mobile data, 3G/4G/LTE whatever).

2: Wi-fi.

3: VPN

You can copy either the Kotlin or the Java version of the helper function.

Kotlin:

@IntRange(from = 0, to = 3)
fun getConnectionType(context: Context): Int {
    var result = 0 // Returns connection type. 0: none; 1: mobile data; 2: wifi
    val cm = context.getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager?
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        cm?.run {
            cm.getNetworkCapabilities(cm.activeNetwork)?.run {
                if (hasTransport(NetworkCapabilities.TRANSPORT_WIFI)) {
                    result = 2
                } else if (hasTransport(NetworkCapabilities.TRANSPORT_CELLULAR)) {
                    result = 1
                } else if (hasTransport(NetworkCapabilities.TRANSPORT_VPN)){
                    result = 3
                }
            }
        }
    } else {
        cm?.run {
            cm.activeNetworkInfo?.run {
                if (type == ConnectivityManager.TYPE_WIFI) {
                    result = 2
                } else if (type == ConnectivityManager.TYPE_MOBILE) {
                    result = 1
                } else if(type == ConnectivityManager.TYPE_VPN) {
                    result = 3
                }
            }
        }
    }
    return result
}

Java:

@IntRange(from = 0, to = 3)
public static int getConnectionType(Context context) {
    int result = 0; // Returns connection type. 0: none; 1: mobile data; 2: wifi
    ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        if (cm != null) {
            NetworkCapabilities capabilities = cm.getNetworkCapabilities(cm.getActiveNetwork());
            if (capabilities != null) {
                if (capabilities.hasTransport(NetworkCapabilities.TRANSPORT_WIFI)) {
                    result = 2;
                } else if (capabilities.hasTransport(NetworkCapabilities.TRANSPORT_CELLULAR)) {
                    result = 1;
                } else if (capabilities.hasTransport(NetworkCapabilities.TRANSPORT_VPN)) {
                    result = 3;
                }
            }
        }
    } else {
        if (cm != null) {
            NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
            if (activeNetwork != null) {
                // connected to the internet
                if (activeNetwork.getType() == ConnectivityManager.TYPE_WIFI) {
                    result = 2;
                } else if (activeNetwork.getType() == ConnectivityManager.TYPE_MOBILE) {
                    result = 1;
                } else if (activeNetwork.getType() == ConnectivityManager.TYPE_VPN) {
                    result = 3;
                }
            }
        }
    }
    return result;
}

I resolve this problem like this:

var util = require('util');

// Our circular object
var obj = {foo: {bar: null}, a:{a:{a:{a:{a:{a:{a:{hi: 'Yo!'}}}}}}}};
obj.foo.bar = obj;

// Generate almost valid JS object definition code (typeof string)
var str = util.inspect(b, {depth: null});

// Fix code to the valid state (in this example it is not required, but my object was huge and complex, and I needed this for my case)
str = str
    .replace(/<Buffer[ \w\.]+>/ig, '"buffer"')
    .replace(/\[Function]/ig, 'function(){}')
    .replace(/\[Circular]/ig, '"Circular"')
    .replace(/\{ \[Function: ([\w]+)]/ig, '{ $1: function $1 () {},')
    .replace(/\[Function: ([\w]+)]/ig, 'function $1(){}')
    .replace(/(\w+): ([\w :]+GMT\+[\w \(\)]+),/ig, '$1: new Date("$2"),')
    .replace(/(\S+): ,/ig, '$1: null,');

// Create function to eval stringifyed code
var foo = new Function('return ' + str + ';');

// And have fun
console.log(JSON.stringify(foo(), null, 4));

Another alternate approach to Diego's is to use a library:

https://github.com/airbnb/DeepLinkDispatch

You can easily declare the URIs you'd like to handle and the parameters you'd like to extract through annotations on the Activity, like:

@DeepLink("path/to/what/i/want")
public class SomeActivity extends Activity {
  ...
}

As a plus, the query parameters will also be passed along to the Activity as well.

SELECT DISTINCT (user_id) 
FROM [user]
WHERE user.user_id In (select user_id from user where ancestry = 'England') 
    And user.user_id In (select user_id from user where ancestry = 'France') 
    And user.user_id In (select user_id from user where ancestry = 'Germany');`

What I did so that input didn't take up the whole line, and be able to place the input in a paragraph, I used a span tag and display to inline-block

html:

<span>cluster:
        <input class="short-input" type="text" name="cluster">
</span>

css:

span{display: inline-block;}

Read textarea value and code-char conversion:

function keys(e) {
  msg.innerHTML = `last key: ${String.fromCharCode(e.keyCode)}`
  
  if(e.key == 'Enter') {
    console.log('send: ', mycon.value);
    mycon.value='';
    e.preventDefault();
  }
}

Push enter to 'send'<br>
<textarea id='mycon' onkeydown="keys(event)"></textarea>

<div id="msg"></div>

And below nice Quake like console on div-s only :)

document.addEventListener('keyup', keys);

let conShow = false

function keys(e) {
  if (e.code == 'Backquote') {
    conShow = !conShow;
    mycon.classList.toggle("showcon");
  } else {
    if (conShow) {
      if (e.code == "Enter") {
        conTextOld.innerHTML+= '<br>' + conText.innerHTML;
        let command=conText.innerHTML.replace(/&nbsp;/g,' ');
        conText.innerHTML='';
        console.log('Send to server:', command); 
      } 
      else if (e.code == "Backspace") {
        conText.innerHTML = conText.innerText.slice(0, -1);
      } else if (e.code == "Space") {
        conText.innerHTML = conText.innerText + '&nbsp;'
      } else {
        conText.innerHTML = conText.innerText + e.key;
      }

    }
  }
}

body {
  margin: 0
}

.con {
  display: flex;
  flex-direction: column;
  justify-content: flex-end;
  align-items: flex-start;
  width: 100%;

.carret {
  height: 20px;
  width: 10px;
  background: red;
  margin-left: 1px;
}

.start { color: red; margin-right: 2px}

Click here and Press tilde ` (and Enter for "send")

<div id="mycon" class="con">
  <div id='conTextOld' class='conTextOld'>Hello!</div>
  <div class="line">
    <div class='start'> > </div>
    <div id='conText' class="conText"></div>
    <div class='carret'></div>
  </div>
</div>

Add the dots to all values:

[[UIColor colorWithRed:222./255. green:227./255. blue: 229./255. alpha:1] CGColor]) ;

Otherwise, you are dividing float by int.

The way to get the selection of the spinner is:

  spinner1.getSelectedItemPosition();

Documentation reference: http://developer.android.com/reference/android/widget/AdapterView.html#getSelectedItemPosition()

However, in your code, the one place you are referencing it is within your setOnItemSelectedListener(). It is not necessary to poll the spinner, because the onItemSelected method gets passed the position as the "position" variable.

So you could change that line to:

TestProjectActivity.this.number = position + 1;

If that does not fix the problem, please post the error message generated when your app crashes.

Try:

sudo -u postgres psql -c 'create database test;'

It can be resolved as follows:

1. Go to Project properties.

2. Then 'Java Compiler' -> Check the box ('Enable project specific settings')

3. Change the compiler compliance level to '5.0' & click ok.

Do rebuild. It will be resolved.

Also, click the checkbox for "Use default compliance settings".

   string[] array = { "cat", "dot", "perls" };

// Use Array.Exists in different ways.
bool a = Array.Exists(array, element => element == "perls");
bool b = Array.Exists(array, element => element == "python");
bool c = Array.Exists(array, element => element.StartsWith("d"));
bool d = Array.Exists(array, element => element.StartsWith("x"));

// Display bools.
Console.WriteLine(a);
Console.WriteLine(b);
Console.WriteLine(c);
Console.WriteLine(d);
----------------------------output-----------------------------------

1)True 2)False 3)True 4)False

In this case you could use something like this:

User::where('this', '=', 1)
    ->whereNotNull('created_at')
    ->whereNotNull('updated_at')
    ->where(function($query){
        return $query
        ->whereNull('alias')
        ->orWhere('alias', '=', 'admin');
    });

It should supply you with a query like:

SELECT * FROM `user` 
WHERE `user`.`this` = 1 
    AND `user`.`created_at` IS NOT NULL 
    AND `user`.`updated_at` IS NOT NULL 
    AND (`alias` IS NULL OR `alias` = 'admin')

char a[2] defines an array of char's. a is a pointer to the memory at the beginning of the array and using == won't actually compare the contents of a with 'ab' because they aren't actually the same types, 'ab' is integer type. Also 'ab' should be "ab" otherwise you'll have problems here too. To compare arrays of char you'd want to use strcmp.

Something that might be illustrative is looking at the typeid of 'ab':

#include <iostream>
#include <typeinfo>
using namespace std;
int main(){
    int some_int =5;
    std::cout << typeid('ab').name() << std::endl;
    std::cout << typeid(some_int).name() << std::endl;
    return 0;
}

on my system this returns:

i
i

showing that 'ab' is actually evaluated as an int.

If you were to do the same thing with a std::string then you would be dealing with a class and std::string has operator == overloaded and will do a comparison check when called this way.

If you wish to compare the input with the string "ab" in an idiomatic c++ way I suggest you do it like so:

#include <iostream>
#include <string>
using namespace std;
int main(){
    string a;
    cout<<"enter ab ";
    cin>>a;
    if(a=="ab"){
         cout<<"correct";
    }
    return 0;
}

This one is due to:

if(a=='ab') , here, a is const char* type (ie : array of char)

'ab' is a constant value,which isn't evaluated as string (because of single quote) but will be evaluated as integer.

Since char is a primitive type inherited from C, no operator == is defined.

the good code should be:

if(strcmp(a,"ab")==0) , then you'll compare a const char* to another const char* using strcmp.

toString is a function, not a property. You'll want this:

console.log(aa.toString());

Alternatively, use join to specify the separator (toString() === join(','))

console.log(aa.join(' and '));

This worked perfectly for me:

sudo rm -rf /Library/Java/JavaVirtualMachines
sudo rm -rf /Library/PreferencePanes/JavaControlPanel.prefPane
sudo rm -rf /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin

If you want it formatted with commas as well as a decimal point (but no currency symbol), such as 3,456,789.12...

decimalVar.ToString("n2");

The easiest way is to use supervisord. Please see full details here: http://supervisord.org/

I figured it out. It's:

 DBCC CHECKIDENT ('tablename', RESEED, newseed)

cursor.execute(sql,array)

Only takes two arguments.
It will iterate the "array"-object and match ? in the sql-string.
(with sanity checks to avoid sql-injection)

One touch point I found that needs to be put in place is "hidden" away in the Proguard configuration. While the HTML reader invokes through the javascript interface just fine when debugging the app, this works no longer as soon as the app was run through Proguard, unless the HTML reader function is declared in the Proguard config file, like so:

-keepclassmembers class <your.fully.qualified.HTML.reader.classname.here> {
    public *; 
}

Tested and confirmed on Android 2.3.6, 4.1.1 and 4.2.1.

You might want to modify your jQuery code a bit to '#demolist li a' so it specifically selects the text that is in the link rather than the text that is in the li element. That would allow you to have a sub-menu without causing issues. Also since your are specifically selecting the a tag you can access it with $(this).text();.

$('#datebox li a').on('click', function(){
    //$('#datebox').val($(this).text());
    alert($(this).text());
});

To further my answer, UPS and FedEx can not deliver to a PO BOX not without using the USPS as final handler. Most shipping software out there will not allow a PO Box zip for their standard services. Examples of PO Box zips are 00604 - RAMEY, PR and 06141 - HARTFORD, CT.

The the whole need to validate zip codes can really be a question of how far do you go, what is the budget, what is the time line.

Like anything with expressions test, test, test, and test again. I had an expression for State validation and found that YORK passed when it should fail. The one time in thousands someone entered New York, New York 10279, ugh.

Also keep in mind, USPS does not like punctuation such as N. Market St. and also has very specific acceptable abbreviations for things like Lane, Place, North, Corporation and the like.

I got this to work:

explicit conversion

    public override object ReadJson(JsonReader reader, Type objectType, object existingValue,
                                    JsonSerializer serializer)
    {
        var jsonObj = serializer.Deserialize<List<SomeObject>>(reader);
        var conversion = jsonObj.ConvertAll((x) => x as ISomeObject);

        return conversion;
    }

I had the same problem, and found the answer. If you use node.js with express, you need to give it its own function in order for the js file to be reached. For example:

const script = path.join(__dirname, 'script.js');
const server = express().get('/', (req, res) => res.sendFile(script))

You should declare metab as integer and then use arithmetic evaluation

declare -i metab num
...
num+=metab
...

Following code works..

datePickerButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            showDialog(0);
        }
    });

@Override
@Deprecated
protected Dialog onCreateDialog(int id) {
    return new DatePickerDialog(this, datePickerListener, year, month, day);
}

private DatePickerDialog.OnDateSetListener datePickerListener = new DatePickerDialog.OnDateSetListener() {
    public void onDateSet(DatePicker view, int selectedYear,
                          int selectedMonth, int selectedDay) {
        day = selectedDay;
        month = selectedMonth;
        year = selectedYear;
        datePickerButton.setText(selectedDay + " / " + (selectedMonth + 1) + " / "
                + selectedYear);
    }
};

You can also use ReadString with \n as a separator:

  f, err := os.Open(filename)
  if err != nil {
    fmt.Println("error opening file ", err)
    os.Exit(1)
  }
  defer f.Close()
  r := bufio.NewReader(f)
  for {
    path, err := r.ReadString(10) // 0x0A separator = newline
    if err == io.EOF {
      // do something here
      break
    } else if err != nil {
      return err // if you return error
    }
  }

Rand does not get you a random number. It gives you the next number in a sequence generated by a pseudorandom number generator. To get a different sequence every time you start your program, you have to seed the algorithm by calling srand.

A (very bad) way to do it is by passing it the current time:

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int main() {
    srand(time(NULL));
    int i, j = 0;
    for(i = 0; i <= 10; i++) {
        j = rand();
        printf("j = %d\n", j);
    }
    return 0;
}

Why this is a bad way? Because a pseudorandom number generator is as good as its seed, and the seed must be unpredictable. That is why you may need a better source of entropy, like reading from /dev/urandom.

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

You're missing your database name:

$sql = "SELECT ID, ListStID, ListEmail, Title FROM ".$entry_database." WHERE ID = ". $ReqBookID .";

And make sure that $entry_database isn't null or empty:

var_dump($entry_database);

Also notice that you don't need to have $ReqBookID in '' as if it's an Int.

<a href="#" onclick="javascript:ShowOld(2367,146986,2)">

I think you should call the super.draw() method first before you do anything in surfaceView's draw method.

if you use mvvm and your itemssource is located in your vm. just call INotifyPropertyChanged for your collection property when you want to refresh.

OnPropertyChanged("YourCollectionProperty");

Referencing Bash Variables Requires Parameter Expansion

The default shell on most Linux distributions is Bash. In Bash, variables must use a dollar sign prefix for parameter expansion. For example:

x=20
y=5
expr $x / $y

Of course, Bash also has arithmetic operators and a special arithmetic expansion syntax, so there's no need to invoke the expr binary as a separate process. You can let the shell do all the work like this:

x=20; y=5
echo $((x / y))

The error message you are getting is a result of Git still thinking that you have not resolved the merge conflicts. In fact, you already have, but you need to tell Git that you have done this by adding the resolved files to the index.

This has the side effect that you could actually just add the files without resolving the conflicts, and Git would still think that you have. So you should be diligent in making sure that you have really resolved the conflicts. You could even run the build and test the code before you commit.

Here's a solution that doesn't use JS at all. It uses checkboxes instead.

You can hide the checkbox by adding this to your CSS:

.container input{
    display: none;
}

And then add some styling to make it look like a button.

Here's the source code that I modded.

For those working with ant, I use this to indicate a pause of 5 seconds:

<tr>
    <td>pause</td>
    <td>5000</td>
    <td></td>
</tr>

That is, target: 5000 and value empty. As the reference indicates:

pause(waitTime)

Arguments:

• waitTime - the amount of time to sleep (in milliseconds)

Wait for the specified amount of time (in milliseconds)

"/" is integer division in python 2 so it is going to round to a whole number. If you would like a decimal returned, just change the type of one of the inputs to float:

float(20)/15 #1.33333333

1. First Possibility: The encrypted string in the Related Web.config File should be same as entered in the connection string (which is shown above) And also, when you change anything in the "Registry Editor" or regedit.exe (as written at Run), then after any change, close the registry editor and reset your Internet Information Services by typing IISRESET at Run. And then login to your environment.

2. Type Services.msc on run and check:

   1. Status of ASP.NET State Services is started. If not, then right click on it, through Properties, change its Startup type to automatic.

   2. Iris ReportManager Service of that particular bank is Listed as Started or not. If its Running, It will show "IRIS REPORT MANAGER SERVICE" as started in the list. If not, then run it by clicking IRIS.REPORTMANAGER.EXE

   Then Again RESET IIS

NUL in Windows seems to be actually a virtual path in any folder. Just like .., . in any filesystem.

Use any folder followed with NUL will work.

Example,

echo 1 > nul
echo 1 > c:\nul
echo 1 > c:\users\nul
echo 1 > c:\windows\nul

have the same effect as /dev/null on Linux.

This was tested on Windows 7, 64 bit.

public static double formatDecimal(double amount) {
    BigDecimal amt = new BigDecimal(amount);
    amt = amt.divide(new BigDecimal(1), 2, BigDecimal.ROUND_HALF_EVEN);
    return amt.doubleValue();
}

Test using Junit

@RunWith(Parameterized.class)
public class DecimalValueParameterizedTest {

  @Parameterized.Parameter
  public double amount;

  @Parameterized.Parameter(1)
  public double expectedValue;

@Parameterized.Parameters
public static List<Object[]> dataSets() {
    return Arrays.asList(new Object[][]{
            {1000.0, 1000.0},
            {1000, 1000.0},
            {1000.00000, 1000.0},

            {1000.111, 1000.11}
    });
}

@Test
public void testDecimalFormat() {

Even without pop the list we can do with set_index

pd.DataFrame(table).T.set_index(0).T
Out[11]: 
0 Heading1 Heading2
1        1        2
2        3        4

Update from_records

table = [['Heading1', 'Heading2'], [1 , 2], [3, 4]]

pd.DataFrame.from_records(table[1:],columns=table[0])
Out[58]: 
   Heading1  Heading2
0         1         2
1         3         4

I once was where you are right now, as a beginner you sometimes feel out of place on how the react way to do this. I'm gonna try to tackle the same way I think of it right now.

States are the cornerstone for communication

Usually what it comes down to is the way that you alter the states in this component in your case you point out three components.

<List /> : Which probably will display a list of items depending on a filter <Filters />: Filter options that will alter your data. <TopBar />: List of options.

To orchestrate all of this interaction you are going to need a higher component let's call it App, that will pass down actions and data to each one of this components so for instance can look like this

<div>
  <List items={this.state.filteredItems}/>
  <Filter filter={this.state.filter} setFilter={setFilter}/>
</div>

So when setFilter is called it will affect the filteredItem and re-render both component;. In case this is not entirely clear I made you an example with checkbox that you can check in a single file:

import React, {Component} from 'react';
import {render} from 'react-dom';

const Person  = ({person, setForDelete}) => (
          <div>
            <input type="checkbox" name="person" checked={person.checked} onChange={setForDelete.bind(this, person)} />
            {person.name}
          </div>
);


class PeopleList extends Component {

  render() {

    return(
      <div>
       {this.props.people.map((person, i) => {
         return <Person key={i} person={person} setForDelete={this.props.setForDelete} />;
       })}
       <div onClick={this.props.deleteRecords}>Delete Selected Records</div>
     </div>
    );
  }

} // end class

class App extends React.Component {

  constructor(props) {
    super(props)
    this.state = {people:[{id:1, name:'Cesar', checked:false},{id:2, name:'Jose', checked:false},{id:3, name:'Marbel', checked:false}]}
  }

  deleteRecords() {
    const people = this.state.people.filter(p => !p.checked);

    this.setState({people});
 }

  setForDelete(person) {
    const checked = !person.checked;
    const people = this.state.people.map((p)=>{
      if(p.id === person.id)
        return {name:person.name, checked};
      return p;
    });

    this.setState({people});
  }

  render () {

    return <PeopleList people={this.state.people} deleteRecords={this.deleteRecords.bind(this)} setForDelete={this.setForDelete.bind(this)}/>;
  }
}

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

Integer foo[] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 };

List<Integer> list = Arrays.asList(foo);
// or
Iterable<Integer> iterable = Arrays.asList(foo);

Though you need to use an Integer array (not an int array) for this to work.

For primitives, you can use guava:

Iterable<Integer> fooBar = Ints.asList(foo);

<dependency>
    <groupId>com.google.guava</groupId>
    <artifactId>guava</artifactId>
    <version>15.0</version>
    <type>jar</type>
</dependency>

For Java8: (from Jin Kwon's answer)

final int[] arr = {1, 2, 3};
final PrimitiveIterator.OfInt i1 = Arrays.stream(arr).iterator();
final PrimitiveIterator.OfInt i2 = IntStream.of(arr).iterator();
final Iterator<Integer> i3 = IntStream.of(arr).boxed().iterator();

lst = ['a', 'b', 'c', 'd', 'e', 'f', 'g'];
lst = lst[0:2] + lst[6:]

This is a single step operation. It does not use a loop and therefore executes fast. It uses list slicing.

Just do the following change

echo off
cls

echo Would you like to do a backup?

pause

copy "\\My_Servers_IP\Shared Drive\FolderName\*" C:\TEST_BACKUP_FOLDER

Reed Copsey published a nice tutorial that writes a trivial RSS app in WinForms, then makes a straight port to WPF, and finally converts to MVVM. It makes a nice introduction to MVVM before you try and tackle a full description like Josh Smith's article. I'm glad that I read Reed's tutorial before Josh's article, because it gives me a little context to understand the details that Josh is digging into.

The only difference between the RANK() and DENSE_RANK() functions is in cases where there is a “tie”; i.e., in cases where multiple values in a set have the same ranking. In such cases, RANK() will assign non-consecutive “ranks” to the values in the set (resulting in gaps between the integer ranking values when there is a tie), whereas DENSE_RANK() will assign consecutive ranks to the values in the set (so there will be no gaps between the integer ranking values in the case of a tie).

For example, consider the set {25, 25, 50, 75, 75, 100}. For such a set, RANK() will return {1, 1, 3, 4, 4, 6} (note that the values 2 and 5 are skipped), whereas DENSE_RANK() will return {1,1,2,3,3,4}.

Edit: Don't use this solution with FreeMarker 2.3.25 and up, especially not .get(prop). See other answers.

You use the built-in keys function, e.g. this should work:

<#list user?keys as prop>
    ${prop} = ${user.get(prop)}
</#list>  

This makes me wonder, when is it advisable to use the EntityManager.getReference() method instead of the EntityManager.find() method?

EntityManager.getReference() is really an error prone method and there is really very few cases where a client code needs to use it.
Personally, I never needed to use it.

EntityManager.getReference() and EntityManager.find() : no difference in terms of overhead

I disagree with the accepted answer and particularly :

If i call find method, JPA provider, behind the scenes, will call

SELECT NAME, AGE FROM PERSON WHERE PERSON_ID = ?

UPDATE PERSON SET AGE = ? WHERE PERSON_ID = ?

If i call getReference method, JPA provider, behind the scenes, will call

UPDATE PERSON SET AGE = ? WHERE PERSON_ID = ?

It is not the behavior that I get with Hibernate 5 and the javadoc of getReference() doesn't say such a thing :

Get an instance, whose state may be lazily fetched. If the requested instance does not exist in the database, the EntityNotFoundException is thrown when the instance state is first accessed. (The persistence provider runtime is permitted to throw the EntityNotFoundException when getReference is called.) The application should not expect that the instance state will be available upon detachment, unless it was accessed by the application while the entity manager was open.

EntityManager.getReference() spares a query to retrieve the entity in two cases :

1) if the entity is stored in the Persistence context, that is the first level cache.
And this behavior is not specific to EntityManager.getReference(), EntityManager.find() will also spare a query to retrieve the entity if the entity is stored in the Persistence context.

You can check the first point with any example.
You can also rely on the actual Hibernate implementation.
Indeed, EntityManager.getReference() relies on the createProxyIfNecessary() method of the org.hibernate.event.internal.DefaultLoadEventListener class to load the entity.
Here is its implementation :

private Object createProxyIfNecessary(
        final LoadEvent event,
        final EntityPersister persister,
        final EntityKey keyToLoad,
        final LoadEventListener.LoadType options,
        final PersistenceContext persistenceContext) {
    Object existing = persistenceContext.getEntity( keyToLoad );
    if ( existing != null ) {
        // return existing object or initialized proxy (unless deleted)
        if ( traceEnabled ) {
            LOG.trace( "Entity found in session cache" );
        }
        if ( options.isCheckDeleted() ) {
            EntityEntry entry = persistenceContext.getEntry( existing );
            Status status = entry.getStatus();
            if ( status == Status.DELETED || status == Status.GONE ) {
                return null;
            }
        }
        return existing;
    }
    if ( traceEnabled ) {
        LOG.trace( "Creating new proxy for entity" );
    }
    // return new uninitialized proxy
    Object proxy = persister.createProxy( event.getEntityId(), event.getSession() );
    persistenceContext.getBatchFetchQueue().addBatchLoadableEntityKey( keyToLoad );
    persistenceContext.addProxy( keyToLoad, proxy );
    return proxy;
}

The interesting part is :

Object existing = persistenceContext.getEntity( keyToLoad );

2) If we don't effectively manipulate the entity, echoing to the lazily fetched of the javadoc.
Indeed, to ensure the effective loading of the entity, invoking a method on it is required.
So the gain would be related to a scenario where we want to load a entity without having the need to use it ? In the frame of applications, this need is really uncommon and in addition the getReference() behavior is also very misleading if you read the next part.

Why favor EntityManager.find() over EntityManager.getReference()

In terms of overhead, getReference() is not better than find() as discussed in the previous point.
So why use the one or the other ?

Invoking getReference() may return a lazily fetched entity.
Here, the lazy fetching doesn't refer to relationships of the entity but the entity itself.
It means that if we invoke getReference() and then the Persistence context is closed, the entity may be never loaded and so the result is really unpredictable. For example if the proxy object is serialized, you could get a null reference as serialized result or if a method is invoked on the proxy object, an exception such as LazyInitializationException is thrown.

It means that the throw of EntityNotFoundException that is the main reason to use getReference() to handle an instance that does not exist in the database as an error situation may be never performed while the entity is not existing.

EntityManager.find() doesn't have the ambition of throwing EntityNotFoundException if the entity is not found. Its behavior is both simple and clear. You will never have surprise as it returns always a loaded entity or null (if the entity is not found) but never an entity under the shape of a proxy that may not be effectively loaded.
So EntityManager.find() should be favored in the very most of cases.

Easiest way to get it by using date pattern - h:mm a, where

• h - Hour in am/pm (1-12)
• m - Minute in hour
• a - Am/pm marker

Code snippet :

DateFormat dateFormat = new SimpleDateFormat("hh:mm a");

Read more on documentation - SimpleDateFormat java 7

Another option might be node-querystring.

It's available in both npm and bower, which is why I have been using it.

Alternative syntax:

INSERT tbl (Col1, Col2, ..., ColN)
  SELECT Col1, Col2, ..., ColN
  FROM Tbl2
  WHERE ...

The select query can (of course) include expressions, case statements, constants/literals, etc.

Angular comes with a limitTo:limit filter, it support limiting first x items and last x items:

<div ng-repeat="item in items|limitTo:4">{{item}}</div>

UPDATE tblKit
SET number = REPLACE(number, 'KIT', 'CH')
WHERE number like 'KIT%'

• SQLFiddle Demo

or simply this if you are sure that you have no values like this CKIT002

UPDATE tblKit
SET number = REPLACE(number, 'KIT', 'CH')

• SQLFiddle Demo

I struggled with the same problem where I was trying to execute an update query like the same as you did-

@Modifying
@Transactional
@Query(value = "UPDATE SAMPLE_TABLE st SET st.status=:flag WHERE se.referenceNo in :ids")
public int updateStatus(@Param("flag")String flag, @Param("ids")List<String> references);

This will work if you have put @EnableTransactionManagement annotation on the main class. Spring 3.1 introduces the @EnableTransactionManagement annotation to be used in on @Configuration classes and enable transactional support.

Here's a different approach. The heart of it was created by turning on the Macro Recorder and filtering the columns per your specifications. Then there's a bit of code to copy the results. It will run faster than looping through each row and column:

Sub FilterAndCopy()
Dim LastRow As Long

Sheets("Sheet2").UsedRange.Offset(0).ClearContents
With Worksheets("Sheet1")
    .Range("$A:$E").AutoFilter
    .Range("$A:$E").AutoFilter field:=1, Criteria1:="#N/A"
    .Range("$A:$E").AutoFilter field:=2, Criteria1:="=String1", Operator:=xlOr, Criteria2:="=string2"
    .Range("$A:$E").AutoFilter field:=3, Criteria1:=">0"
    .Range("$A:$E").AutoFilter field:=5, Criteria1:="Number"
    LastRow = .Range("A" & .Rows.Count).End(xlUp).Row
    .Range("A1:A" & LastRow).SpecialCells(xlCellTypeVisible).EntireRow.Copy _
            Destination:=Sheets("Sheet2").Range("A1")
End With
End Sub

As a side note, your code has more loops and counter variables than necessary. You wouldn't need to loop through the columns, just through the rows. You'd then check the various cells of interest in that row, much like you did.

You can also use the sqldf package in R.

Z <- sqldf('SELECT DISTINCT tablename.columnname FROM tablename ')

If you want to redirect on url instead of activity from your adapter class then pass context of with startactivity.

btnInstall.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent=new Intent(Intent.ACTION_VIEW, Uri.parse(link));
                intent.setData(Uri.parse(link));
                context.startActivity(intent);
            }
        });

$(document).ready(function() {
    $("#form1").validate({
        rules: {
            field1: "required"
        },
        messages: {
            field1: "Please specify your name"
        }
    })
});

<form id="form1" name="form1">
     Field 1: <input id="field1" type="text" class="required">
    <input id="btn" type="submit" value="Validate">
</form>

You are also you using type="button". And I'm not sure why you ought to separate the submit button, place it within the form. It's more proper to do it that way. This should work.

This works for me. in place of customTheme you can put you theme in styles. in this code you can also change the font and text size.

    <style name="MyTheme.NavMenu" parent="CustomTheme">
            <item name="android:textSize">16sp</item>
            <item name="android:fontFamily">@font/ssp_semi_bold</item>
            <item name="android:textColorPrimary">@color/yourcolor</item>
        </style>

here is my navigation view

<android.support.design.widget.NavigationView

You're trying to use k (which is a list) as a key for d. Lists are mutable and can't be used as dict keys.

Also, you're never initializing the lists in the dictionary, because of this line:

if k not in d == False:

Which should be:

if k not in d == True:

Which should actually be:

if k not in d:

also this works too

• Not using css background
• Only 1 div to clip it
• Resized to minimum width than keep correct aspect ratio
• Crop from center (vertically and horizontally, you can adjust that with the top, lef & transform)

Be careful if you're using a theme or something, they'll often declare img max-width at 100%. You got to make none. Test it out :)

If you are not comfortable with bash, you can continue to work in a standard windows command (i.e. DOS) shell.

For this to work you must add C:\cygwin\bin (or your local alternative) to the Windows PATH variable.

With this done, you may: 1) Open a command (DOS) shell 2) Change the directory to the location of your code (c:, then cd path\to\file) 3) gcc myProgram.c -o myProgram

As mentioned in nik's response, the "Using Cygwin" documentation is a great place to learn more.

Justin has given you some very fine tips :)

You will also get that error if the cell where you are performing the calculation has an error resulting from a formula.

For example if Cell A1 has #DIV/0! error then you will get "Excel VBA Run-time error '13' Type mismatch" when performing this code

Sheets("Sheet1").Range("A1").Value - 1

I have made some slight changes to your code. Could you please test it for me? Copy the code with the line numbers as I have deliberately put them there.

You can install them by

sudo apt-get install -y libav-tools

There is a way of doing this and it actually looks similar to R

new = old[['A', 'C', 'D']].copy()

Here you are just selecting the columns you want from the original data frame and creating a variable for those. If you want to modify the new dataframe at all you'll probably want to use .copy() to avoid a SettingWithCopyWarning.

An alternative method is to use filter which will create a copy by default:

new = old.filter(['A','B','D'], axis=1)

Finally, depending on the number of columns in your original dataframe, it might be more succinct to express this using a drop (this will also create a copy by default):

new = old.drop('B', axis=1)

I want to suggest a common solution for those requirements, maybe it is a use for you: AutoIt. With that program, you can write scripts on top of any window like Putty and execute all commands you want to (like button pressing or mouse clicking in textboxes or buttons).

This way you can emulate all steps you are always doing with Putty.

I used this solution: in TableRow, I created for every cell LinearLayout with vertical line and actual cell in it, and after every TableRow, I added a horizontal line.

Look at the code below:

<TableLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:shrinkColumns="1">

    <TableRow            
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" >

            <LinearLayout 
                android:orientation="horizontal"
                android:layout_height="match_parent"
                android:layout_weight="1">

                <TextView 
                    android:layout_width="0dp"
                    android:layout_height="wrap_content"
                    android:gravity="center"/>

            </LinearLayout>

            <LinearLayout 
                android:orientation="horizontal"
                android:layout_height="match_parent"
                android:layout_weight="1">

                <View
                    android:layout_height="match_parent"
                    android:layout_width="1dp"
                    android:background="#BDCAD2"/>

                <TextView 
                    android:layout_width="0dp"
                    android:layout_height="wrap_content"
                    android:gravity="center"/>

            </LinearLayout>
      </TableRow>

      <View
        android:layout_height="1dip"
        android:background="#BDCAD2" />

If htaccess is an option this will make all PDF links download instead of opening in browser

<FilesMatch "\.(?i:pdf)$">

</FilesMatch>

Real example from my code:

return selected.Select(query => query.Name).Aggregate((a, b) => a + ", " + b);

A query is an object that has a Name property which is a string, and I want the names of all the queries on the selected list, separated by commas.

The 60 you're passing is just the initial capacity for internal storage. It's a hint on how big you think it might be, yet of course it's not limited by that. If you need to preset values you'll have to set them yourself, e.g.:

for (int i = 0; i < 60; i++) {
    list.add(0);
}

Can't you just add a reference to System.Web and then you can use Server.MapPath ?

Edit: Nowadays I'd recommend using the HostingEnvironment.MapPath Method:

It's a static method in System.Web assembly that Maps a virtual path to a physical path on the server. It doesn't require a reference to HttpContext.

You can use a \r (carriage return) to return the cursor to the beginning of the line:

printf("hello");
printf("\rbye");

This will print bye on the same line. It won't erase the existing characters though, and because bye is shorter than hello, you will end up with byelo. To erase it you can make your new print longer to overwrite the extra characters:

printf("hello");
printf("\rbye  ");

Or, first erase it with a few spaces, then print your new string:

printf("hello");
printf("\r          ");
printf("\rbye");

That will print hello, then go to the beginning of the line and overwrite it with spaces, then go back to the beginning again and print bye.

Try CSS3 Textshadow.

.box_textshadow {
     text-shadow: 2px 2px 0px #FF0000; /* FF3.5+, Opera 9+, Saf1+, Chrome, IE10 */
}

Try it yourself on css3please.com.

$command = 'convert -density 300 ';
                        if(Input::Post('height')!='' && Input::Post('width')!=''){
                            $command.='-resize '.Input::Post('width').'x'.Input::Post('height').' ';
                        }
                        $command.=$svg.' '.$source;
                        exec($command);
                        @unlink($svg);

The correct answer, is indeed the correct answer to get the int value.

But, if you're just checking to make sure it's Sunday for example... Consider using the following code, instead of casting to an int. This provides much more readability.

if (yourDateTimeObject.DayOfWeek == DayOfWeek.Sunday)
{
    // You can easily see you're checking for sunday, and not just "0"
}

You have to call next() before you can start reading values from the first row. beforeFirst puts the cursor before the first row, so there's no data to read.

Solution For Laravel Framework

As per Laravel 5.4.* documentation; You have to set the default string length inside the boot method of the app/Providers/AppServiceProvider.php file as follows:

use Illuminate\Support\Facades\Schema;

public function boot() 
{
    Schema::defaultStringLength(191); 
}

Explanation of this fix, given by Laravel 5.4.* documentation:

Laravel uses the utf8mb4 character set by default, which includes support for storing "emojis" in the database. If you are running a version of MySQL older than the 5.7.7 release or MariaDB older than the 10.2.2 release, you may need to manually configure the default string length generated by migrations in order for MySQL to create indexes for them. You may configure this by calling the Schema::defaultStringLength method within your AppServiceProvider.

Alternatively, you may enable the innodb_large_prefix option for your database. Refer to your database's documentation for instructions on how to properly enable this option.

I would rather write a little JavaScript than make the CSS less manageable.

First, only apply the CSS animation on a data attribute change:

.progbar[data-animation="barshine"] {
    animation: barshine 1s linear;
}

Then add javascript to toggle the animation at half the delay amount.

var progbar = document.querySelector('.progbar');
var on = false;

setInterval(function () {
    progbar.setAttribute('data-animation', (on) ? 'barshine' : '');
    on = !on;
}, 3000);

Or if you don't want the animation to run when the tab is hidden:

var progbar = document.querySelector('.progbar');
var on = false;

var update = function () {
    progbar.setAttribute('data-animation', (on) ? 'barshine' : '');
    on = !on;
    setTimer();
};

var setTimer = function () {
    setTimeout(function () {
        requestAnimationFrame(update);
    }, 3000);
};

setTimer();

I use the following alternative to get default/optional params and "kind-of-overloaded" constructors with variable number of params:

private x?: number;
private y?: number;

constructor({x = 10, y}: {x?: number, y?: number}) {
 this.x = x;
 this.y = y;
}

I know it's not the prettiest code ever, but one gets used to it. No need for the additional Interface and it allows private members, which is not possible when using the Interface.

If you don't want to check on upper or lowercases you can use the following method.

String str = "India" 
compareString(str) 

def compareString(String str){ 
  def str2 = "india" 
  if( str2.toUpperCase() == str.toUpperCase() ) { 
    println "same" 
  }else{ 
    println "not same" 
  } 
}

So now if you change str to "iNdIa" it'll still work, so you lower the chance that you make a typo.

It contains the allocated size, 10. The unassigned indexes will contain the default value which is 0 for int.

Try this, in your parent frame set up you IFRAMEs like this:

<iframe id="frame1" src="inner.html#frame1"></iframe>
<iframe id="frame2" src="inner.html#frame2"></iframe>
<iframe id="frame3" src="inner.html#frame3"></iframe>

Note that the id of each frame is passed as an anchor in the src.

then in your inner html you can access the id of the frame it is loaded in via location.hash:

<button onclick="alert('I am frame: ' + location.hash.substr(1))">Who Am I?</button>

then you can access parent.document.getElementById() to access the iframe tag from inside the iframe

Your question is mixing a few different concepts. You started out saying you wanted to run sites on the same server using the same domain, but in different folders. That doesn't require any special setup. Once you get the single domain running, you just create folders under that docroot.

Based on the rest of your question, what you really want to do is run various sites on the same server with their own domain names.

The best documentation you'll find on the topic is the virtual host documentation in the apache manual.

There are two types of virtual hosts: name-based and IP-based. Name-based allows you to use a single IP address, while IP-based requires a different IP for each site. Based on your description above, you want to use name-based virtual hosts.

The initial error you were getting was due to the fact that you were using different ports than the NameVirtualHost line. If you really want to have sites served from ports other than 80, you'll need to have a NameVirtualHost entry for each port.

Assuming you're starting from scratch, this is much simpler than it may seem.

If you are using 2.3 or earlier, the first thing you need to do is tell Apache that you're going to use name-based virtual hosts.

NameVirtualHost *:80

If you are using 2.4 or later do not add a NameVirtualHost line. Version 2.4 of Apache deprecated the NameVirtualHost directive, and it will be removed in a future version.

Now your vhost definitions:

<VirtualHost *:80>
    DocumentRoot "/home/user/site1/"
    ServerName site1
</VirtualHost>

<VirtualHost *:80>
    DocumentRoot "/home/user/site2/"
    ServerName site2
</VirtualHost>

You can run as many sites as you want on the same port. The ServerName being different is enough to tell Apache which vhost to use. Also, the ServerName directive is always the domain/hostname and should never include a path.

If you decide to run sites on a port other than 80, you'll always have to include the port number in the URL when accessing the site. So instead of going to http://example.com you would have to go to http://example.com:81

It may be helpful for someone, although there is no precise answer to this question.

My soap url has a non-standard port(9087 for example), and firewall blocked that request and I took each time this error:

ERROR - 2017-12-19 20:44:11 --> Fatal Error - SOAP-ERROR: Parsing WSDL: Couldn't load from 'http://soalurl.test:9087/orawsv?wsdl' : failed to load external entity "http://soalurl.test:9087/orawsv?wsdl"

I allowed port in firewall and solved the error!

You can also do it this way, allowing polymorphism:

class Base {
public:
   virtual std::ostream& dump(std::ostream& o) const {
      return o << "Base: " << b << "; ";
   }
private:
  int b;
};

class Derived : public Base {
public:
   virtual std::ostream& dump(std::ostream& o) const {
      return o << "Derived: " << d << "; ";
   }
private:
   int d;
}

std::ostream& operator<<(std::ostream& o, const Base& b) { return b.dump(o); }

You cannot select on specific values (or types of values). You'd either make a reverse index (map numbers back to (lists of) keys) or you have to loop through all values every time.

If you are processing numbers in arbitrary order anyway, you may as well loop through all items:

for key, value in inputdict.items():
    # do something with value
    inputdict[key] = newvalue

otherwise I'd go with the reverse index:

from collections import defaultdict

reverse = defaultdict(list)
for key, value in inputdict.items():
    reverse[value].append(key)

Now you can look up keys by value:

for key in reverse[value]:
    inputdict[key] = newvalue

If your post keys have to be parsed and the keys are sequences with data, you can try this:

Post data example: Storeitem|14=data14

foreach($_POST as $key => $value){
    $key=Filterdata($key); $value=Filterdata($value);
    echo($key."=".$value."<br>");
}

then you can use strpos to isolate the end of the key separating the number from the key.

Suppose you need only x:target/classes in your classpath. Then you just add this folder to your classpath and %IDEA%\lib\idea_rt.jar. Now it will work. That's it.

In a nutshell, boilerplate codes are repetitive codes required to be included in the application with little to no change by the program/framework, and contribute nothing to the logic of the application. When you write pseudo codes you can remove boilerplate codes. The recommendation is to use a proper Editor that generates boilerplate codes.

in HTML, the boilerplate codes in the interface.

<!DOCTYPE html>   
<html>   
   <head>   
      <title></title>   
   </head>   
   <body> </body>   
</html>

in C#, The boilerplate codes of properties.

class Price
{   
  private string _price;   
  public string Price
  {   
     get {return _price;}   
     set {_price= value;}   
  }   
}  

>>> dict(a=2,b=4)
{'a': 2, 'b': 4}

Will add the value in the python dictionary.

I was having the same error under Windows using emacs 24.5.1 to connect to some company servers through /ssh:user@host. What solved my problem was setting the "tramp-default-method" variable to "plink" and whenever I connect to a server I ommit the ssh protocol. You need to have PuTTY's plink.exe installed for this to work.

Solution

1. M-x customize-variable (and then hit Enter)
2. tramp-default-method (and then hit Enter again)
3. On the text field put plink and then Apply and Save the buffer
4. Whenever I try to access a remote server I now use C-x-f /user@host: and then input the password. The connection is now correctly made under Emacs on Windows to my remote server.

2021 Solution

If you're still getting this error message:

TS7016: Could not find a declaration file for module './myjsfile'

Then you might need to add the following to tsconfig.json

{
  "compilerOptions": {
    ...
    "allowJs": true,
    "checkJs": false,
    ...
  }
}

This prevents typescript from trying to apply module types to the imported javascript.

Something like this should work

var text = $('#toptitle').text();
if (text == 'Profil'){
    $('#toptitle').text('New Word');
}

If you have integers in your file fscanf returns 1 until integer occurs. For example:

FILE *in = fopen("./task.in", "r");
int length = 0;
int counter;
int sequence;

for ( int i = 0; i < 10; i++ ) {
    counter = fscanf(in, "%d", &sequence);
    if ( counter == 1 ) {
        length += 1;
    }
}

To find out the end of the file with symbols you can use EOF. For example:

char symbol;
FILE *in = fopen("./task.in", "r");

for ( ; fscanf(in, "%c", &symbol) != EOF; ) {
    printf("%c", symbol); 
}

You will receive these parameters on your query result:

    "fieldCount": 0,
    "affectedRows": 1,
    "insertId": 66,
    "serverStatus": 2,
    "warningCount": 1,
    "message": "",
    "protocol41": true,
    "changedRows": 0

The insertId is exactly what you need.

The best performant solution is to stop using library calls and just recognize that you're working with two arrays. A hand-rolled implementation is both short and also faster than every other solution I've seen here.

function startsWith2(str, prefix) {
    if (str.length < prefix.length)
        return false;
    for (var i = prefix.length - 1; (i >= 0) && (str[i] === prefix[i]); --i)
        continue;
    return i < 0;
}

For performance comparisons (success and failure), see http://jsperf.com/startswith2/4. (Make sure you check for later versions that may have trumped mine.)

Then for each table where I have a hierarchy, I create a trigger

CREATE TRIGGER nomenclature_tree_tr AFTER INSERT OR UPDATE ON nomenclature FOR EACH ROW EXECUTE PROCEDURE nomen_tree('my_db.nomenclature', 'my_db.nom_helper', 'parent_id');

For populating a closure table from existing hierarchy I use this stored procedure:

CREATE FUNCTION rebuild_tree(tbl_base text, tbl_closure text, fld_parent text) RETURNS void
    LANGUAGE plpgsql
    AS $$
BEGIN
    EXECUTE 'TRUNCATE ' || tbl_closure || ';
    INSERT INTO ' || tbl_closure || ' (child_id,ancestor_id,depth) 
        WITH RECURSIVE tree AS
      (
        SELECT id AS child_id,id AS ancestor_id,0 AS depth FROM ' || tbl_base || '
        UNION ALL 
        SELECT t.id,ancestor_id,depth+1 FROM ' || tbl_base || ' AS t
        JOIN tree ON child_id = ' || fld_parent || '
      )
      SELECT * FROM tree;';
END;
$$;

Closure tables are defined with 3 columns - ANCESTOR_ID, DESCENDANT_ID, DEPTH. It is possible (and I even advice) to store records with same value for ANCESTOR and DESCENDANT, and a value of zero for DEPTH. This will simplify the queries for retrieval of the hierarchy. And they are very simple indeed:

-- get all descendants
SELECT tbl_orig.*,depth FROM tbl_closure LEFT JOIN tbl_orig ON descendant_id = tbl_orig.id WHERE ancestor_id = XXX AND depth <> 0;
-- get only direct descendants
SELECT tbl_orig.* FROM tbl_closure LEFT JOIN tbl_orig ON descendant_id = tbl_orig.id WHERE ancestor_id = XXX AND depth = 1;
-- get all ancestors
SELECT tbl_orig.* FROM tbl_closure LEFT JOIN tbl_orig ON ancestor_id = tbl_orig.id WHERE descendant_id = XXX AND depth <> 0;
-- find the deepest level of children
SELECT MAX(depth) FROM tbl_closure WHERE ancestor_id = XXX;

Most likely .gitignore files are at play. Note that .gitignore files can appear not only at the root level of the repo, but also at any sub level. You might try this from the root level to find them:

find . -name ".gitignore"

and then examine the results to see which might be preventing your subdirs from being added.

There also might be submodules involved. Check the offending directories for ".gitmodules" files.

If you are using Docker toolkit on window 10 home you will need to access the webpage through docker-machine ip command. It is generally 192.168.99.100:

It is assumed that you are running with publish command like below.

docker run -it -p 8080:8080 demo

With Window 10 pro version you can access with localhost or corresponding loopback 127.0.0.1:8080 etc (Tomcat or whatever you wish). This is because you don't have a virtual box there and docker is running directly on Window Hyper V and loopback is directly accessible.

Verify the hosts file in window for any digression. It should have 127.0.0.1 mapped to localhost

API Sanity Checker — test framework for C/C++ libraries:

An automatic generator of basic unit tests for a shared C/C++ library. It is able to generate reasonable (in most, but unfortunately not all, cases) input data for parameters and compose simple ("sanity" or "shallow"-quality) test cases for every function in the API through the analysis of declarations in header files.

The quality of generated tests allows to check absence of critical errors in simple use cases. The tool is able to build and execute generated tests and detect crashes (segfaults), aborts, all kinds of emitted signals, non-zero program return code and program hanging.

Unique features in comparison with CppUnit, Boost and Google Test:

• Automatic generation of test data and input arguments (even for complex data types)
• Modern and highly reusable specialized types instead of fixtures and templates

simply run

sudo apt install php-xml

its worked for me

The action attribute will default to the current URL. It is the most reliable and easiest way to say "submit the form to the same place it came from".

There is no reason to use $_SERVER['PHP_SELF'], and # doesn't submit the form at all (unless there is a submit event handler attached that handles the submission).

You can allow the Docker user (here: root) to access the X11 display:

XSOCK=/tmp/.X11-unix
xhost +SI:localuser:root 
docker run -t -i --rm -v $XSOCK:$XSOCK:ro -e DISPLAY=unix$(DISPLAY) image 
xhost -SI:localuser:root

Use max():

 
Using itemgetter():

In [53]: lis=[(101, 153), (255, 827), (361, 961)]

In [81]: from operator import itemgetter

In [82]: max(lis,key=itemgetter(1))[0]    #faster solution
Out[82]: 361

using lambda:

In [54]: max(lis,key=lambda item:item[1])
Out[54]: (361, 961)

In [55]: max(lis,key=lambda item:item[1])[0]
Out[55]: 361

timeit comparison:

In [30]: %timeit max(lis,key=itemgetter(1))
1000 loops, best of 3: 232 us per loop

In [31]: %timeit max(lis,key=lambda item:item[1])
1000 loops, best of 3: 556 us per loop

try to use

end($array);

Use StadiumBorder shape

              OutlineButton(
                onPressed: () {},
                child: Text("Follow"),
                borderSide: BorderSide(color: Colors.blue),
                shape: StadiumBorder(),
              )

[a-zA-Z0-9~@#\^\$&\*\(\)-_\+=\[\]\{\}\|\\,\.\?\s]*

This would do the matching, if you only want to allow that just wrap it in ^$ or any other delimiters that you see appropriate, if you do this no specific disallow logic is needed.

I found this blog post which cleared up a few things. To quote the most relevant bit:

Mixed Active Content is now blocked by default in Firefox 23!

What is Mixed Content?
When a user visits a page served over HTTP, their connection is open for eavesdropping and man-in-the-middle (MITM) attacks. When a user visits a page served over HTTPS, their connection with the web server is authenticated and encrypted with SSL and hence safeguarded from eavesdroppers and MITM attacks.

However, if an HTTPS page includes HTTP content, the HTTP portion can be read or modified by attackers, even though the main page is served over HTTPS. When an HTTPS page has HTTP content, we call that content “mixed”. The webpage that the user is visiting is only partially encrypted, since some of the content is retrieved unencrypted over HTTP. The Mixed Content Blocker blocks certain HTTP requests on HTTPS pages.

The resolution, in my case, was to simply ensure the jquery includes were as follows (note the removal of the protocol):

<link rel="stylesheet" href="//code.jquery.com/ui/1.8.10/themes/smoothness/jquery-ui.css" type="text/css">
<script type="text/javascript" src="//ajax.aspnetcdn.com/ajax/jquery.ui/1.8.10/jquery-ui.min.js"></script>

Note that the temporary 'fix' is to click on the 'shield' icon in the top-left corner of the address bar and select 'Disable Protection on This Page', although this is not recommended for obvious reasons.

UPDATE: This link from the Firefox (Mozilla) support pages is also useful in explaining what constitutes mixed content and, as given in the above paragraph, does actually provide details of how to display the page regardless:

Most websites will continue to work normally without any action on your part.

If you need to allow the mixed content to be displayed, you can do that easily:

Click the shield icon Mixed Content Shield in the address bar and choose Disable Protection on This Page from the dropdown menu.

The icon in the address bar will change to an orange warning triangle Warning Identity Icon to remind you that insecure content is being displayed.

To revert the previous action (re-block mixed content), just reload the page.

overcommit_memory

Controls overcommit of system memory, possibly allowing processes to allocate (but not use) more memory than is actually available.

0 - Heuristic overcommit handling. Obvious overcommits of address space are refused. Used for a typical system. It ensures a seriously wild allocation fails while allowing overcommit to reduce swap usage. root is allowed to allocate slighly more memory in this mode. This is the default.

1 - Always overcommit. Appropriate for some scientific applications.

2 - Don't overcommit. The total address space commit for the system is not permitted to exceed swap plus a configurable percentage (default is 50) of physical RAM. Depending on the percentage you use, in most situations this means a process will not be killed while attempting to use already-allocated memory but will receive errors on memory allocation as appropriate.

Try changing the color of your "border-top" attribute to white

If you don't feel like importing anything, you can try:

raise SystemExit, 0

On Servlet 3.0 or newer you could just specify

<web-app ...>
    <error-page>
        <location>/general-error.html</location>
    </error-page>
</web-app>

But as you're still on Servlet 2.5, there's no other way than specifying every common HTTP error individually. You need to figure which HTTP errors the enduser could possibly face. On a barebones webapp with for example the usage of HTTP authentication, having a disabled directory listing, using custom servlets and code which can possibly throw unhandled exceptions or does not have all methods implemented, then you'd like to set it for HTTP errors 401, 403, 500 and 503 respectively.

<error-page>
    <!-- Missing login -->
    <error-code>401</error-code>
    <location>/general-error.html</location>
</error-page>
<error-page>
    <!-- Forbidden directory listing -->
    <error-code>403</error-code>
    <location>/general-error.html</location>
</error-page>
<error-page>
    <!-- Missing resource -->
    <error-code>404</error-code>
    <location>/Error404.html</location>
</error-page>
<error-page>
    <!-- Uncaught exception -->
    <error-code>500</error-code>
    <location>/general-error.html</location>
</error-page>
<error-page>
    <!-- Unsupported servlet method -->
    <error-code>503</error-code>
    <location>/general-error.html</location>
</error-page>

That should cover the most common ones.

If you know what values you are looking for, usually a status code, the following can be helpful:

select case when 0 in (PAGE1STATUS ,PAGE2STATUS ,PAGE3STATUS,
PAGE4STATUS,PAGE5STATUS ,PAGE6STATUS) then 0 else 1 end
FROM CUSTOMERS_FORMS

Use max-width:100%;, height: auto; and display:block; as follow:

image {
    max-width:100%;
    height: auto;
    display:block;
}

cut -d: -f1

or

awk -F: '{print $1}'

or

sed 's/:.*//'

    public <T1 extends Object, T2 extends Object> void copy(T1 origEntity, T2 destEntity) {
        DozerBeanMapper mapper = new DozerBeanMapper();
        mapper.map(origEntity,destEntity);
    }

 <dependency>
            <groupId>net.sf.dozer</groupId>

        </dependency>

simple we can also use for an imageview

    imageView.setColorFilter(ContextCompat.getColor(context,
R.color.COLOR_YOUR_COLOR));

Based on this reference, the next approach worked for me:

// e.g. format = "dd/MM/yyyy", dateString = "10/07/2017" 
var formatInfo = new DateTimeFormatInfo()
{
     ShortDatePattern = format
};
date = Convert.ToDateTime(dateString, formatInfo);

This is a possible generic implementation using a bit of reflection (pseudo-code, don't have VS now):

public class DtoMapper<DtoType>
{
    Dictionary<string,PropertyInfo> properties;

    public DtoMapper()
    {
        // Cache property infos
        var t = typeof(DtoType);
        properties = t.GetProperties().ToDictionary(p => p.Name, p => p);
     }

    public DtoType Map(Dto dto)
    {
        var instance = Activator.CreateInstance(typeOf(DtoType));

        foreach(var p in properties)
        {
            p.SetProperty(
                instance, 
                Convert.Type(
                    p.PropertyType, 
                    dto.Items[Array.IndexOf(dto.ItemsNames, p.Name)]);

            return instance;
        }
    }

Usage:

var mapper = new DtoMapper<Model>();
var modelInstance = mapper.Map(dto);

This will be slow when you create the mapper instance but much faster later.

Collections.reverse() can do that job for you if you put your numbers in a List of Integers.

List<Integer> list = Arrays.asList(1, 4, 9, 16, 9, 7, 4, 9, 11);
System.out.println(list);
Collections.reverse(list);
System.out.println(list);

Output:

[1, 4, 9, 16, 9, 7, 4, 9, 11]
[11, 9, 4, 7, 9, 16, 9, 4, 1]

see man nm

GNU nm lists the symbols from object files objfile.... If no object files are listed as arguments, nm assumes the file a.out.

Take a look at cat /proc/stat

grep 'cpu ' /proc/stat | awk '{usage=($2+$4)*100/($2+$4+$5)} END {print usage "%"}'

EDIT please read comments before copy-paste this or using this for any serious work. This was not tested nor used, it's an idea for people who do not want to install a utility or for something that works in any distribution. Some people think you can "apt-get install" anything.

NOTE: this is not the current CPU usage, but the overall CPU usage in all the cores since the system bootup. This could be very different from the current CPU usage. To get the current value top (or similar tool) must be used.

Current CPU usage can be potentially calculated with:

awk '{u=$2+$4; t=$2+$4+$5; if (NR==1){u1=u; t1=t;} else print ($2+$4-u1) * 100 / (t-t1) "%"; }' \
<(grep 'cpu ' /proc/stat) <(sleep 1;grep 'cpu ' /proc/stat)

Here is a static class implementing Start(), Stop(), and IsStarted() for IISExpress. It is parametrized by hard-coded static properties and passes invocation information via the command-line arguments to IISExpress. It uses the Nuget package, MissingLinq.Linq2Management, which surprisingly provides information missing from System.Diagnostics.Process, specifically, the command-line arguments that can then be used to help disambiguate possible multiple instances of IISExpress processes, since I don't preserve the process Ids. I presume there is a way to accomplish the same thing with just System.Diagnostics.Process, but life is short. Enjoy.

When it is the case that you want to use any kind of external file, there is certainly a way to put them in a folder within your project, but not as valid as getting them from resources. In a regular Visual Studio project, you should have a Resources.resx file under the Properties section, if not, you can easily add your own Resource.resx file. And add any kind of file in it, you can reach the walkthrough for adding resource files to your project here.

After having resource files in your project, calling them is easy as this:

var myIcon = Resources.MyIconFile;

Of course you should add the using Properties statement like this:

using <namespace>.Properties;

If str is null, undefined or 0, this code will set it to "hai"

function(nodeBox, str) {
  str = str || "hai";
.
.
.

If you also need to pass 0, you can use:

function(nodeBox, str) {
  if (typeof str === "undefined" || str === null) { 
    str = "hai"; 
  }
.
.
.

Simple read loop use this code

var resx = ResourcesName.ResourceManager.GetResourceSet(CultureInfo.CurrentUICulture, false, false);

foreach (DictionaryEntry dictionaryEntry in resx)
{
    Console.WriteLine("Key: " + dictionaryEntry.Key);
    Console.WriteLine("Val: " + dictionaryEntry.Value);
}

when I started xampp on my windows 10 there were many options available, unfortunately every one of them failed. I ll list them so that you don't go through all of them again.

THINGS THAT DIDN'T WORK

1) i installed xampp initially in a different drive and not c because of UAC issues so i uninstalled Xampp and installed it again in c (didn't work) 2) while reinstalling i deactivated the antivirus as setup said that some installing might not end up properly(realized it doesn't matter :) lmao) 3) i tried to change ports several times of xampp from 80 to some different number like 8080 etc. still nothing happened 4) i then tried using firefox as it is believed that internet explorer or internet edge is not a good browser for xampp 5) after that i went to config file i.e config.inc inside phpmyadmin folder and did some crap as were given in the instructions. Failure it was 6) then i closed laptop and went to sleep(XD srry leave this point) 7) then i tried searching for windows web services in the services.msc to disable it. i couldn't find it

WHAT WORKED

On eighth time i got success.This is what i did 8)In control panel, where you have actions , modules PIDs, Ports you will see Services under which you will see gray boxes which are actually checkboxes but are empty initially. i checked it so that xampp services start and apache services start. now you will see them ticked. After that just change the port of xampp and apache to 80.

I hope it helps. cheers ;)

A concise solution:

location.search
  .slice(1)
  .split('&')
  .map(p => p.split('='))
  .reduce((obj, pair) => {
    const [key, value] = pair.map(decodeURIComponent);
    obj[key] = value;
    return obj;
  }, {});

Just for the sake of people who landed here for the same reason I did:

Don't use reserved keywords

I named a function in my class definition delete(), which is a reserved keyword and should not be used as a function name. Renaming it to deletion() (which also made sense semantically in my case) resolved the issue.

For a list of reserved keywords: http://en.cppreference.com/w/cpp/keyword

I quote: "Since they are used by the language, these keywords are not available for re-definition or overloading. "

That what manual says about setOnClickListener method is:

public void setOnClickListener (View.OnClickListener l)

Added in API level 1 Register a callback to be invoked when this view is clicked. If this view is not clickable, it becomes clickable.

Parameters

l View.OnClickListener: The callback that will run

And normally you have to use it like this

public class ExampleActivity extends Activity implements OnClickListener {
    protected void onCreate(Bundle savedValues) {
        ...
        Button button = (Button)findViewById(R.id.corky);
        button.setOnClickListener(this);
    }

    // Implement the OnClickListener callback
    public void onClick(View v) {
      // do something when the button is clicked
    }
    ...
}

If you're using Express, then you can use its compress method as part of the configuration:

var express = require('express');
var app = express.createServer();
app.use(express.compress());

And you can find more on compress here: http://expressjs.com/api.html#compress

And if you're not using Express... Why not, man?! :)

NOTE: (thanks to @ankitjaininfo) This middleware should be one of the first you "use" to ensure all responses are compressed. Ensure that this is above your routes and static handler (eg. how I have it above).

NOTE: (thanks to @ciro-costa) Since express 4.0, the express.compress middleware is deprecated. It was inherited from connect 3.0 and express no longer includes connect 3.0. Check Express Compression for getting the middleware.

Try this in a RelativeLayout:

ImageView image = new ImageView(this);
image.SetZ(float z);

It works for me.

I think the docs aren't wonderful at exposing how to do this. It has been a supported feature for some time, however, and there are some details in this pull request.

So there are three different ways to do this:

Option A) Create a new session with the profile

    dev = boto3.session.Session(profile_name='dev')

Option B) Change the profile of the default session in code

    boto3.setup_default_session(profile_name='dev')

Option C) Change the profile of the default session with an environment variable

    $ AWS_PROFILE=dev ipython
    >>> import boto3
    >>> s3dev = boto3.resource('s3')

Your methods don't refer to an object (that is, self), so you should use the @staticmethod decorator:

class MathsOperations:
    @staticmethod
    def testAddition (x, y):
        return x + y

    @staticmethod
    def testMultiplication (a, b):
        return a * b

I found it easier to edit the project file directly e.g. YourApp.csproj.

You can do this by modifying ApplicationIcon property element:

<ApplicationIcon>..\Path\To\Application.ico</ApplicationIcon>

Also, if you create an MSI installer for your application e.g. using WiX, you can use the same icon again for display in Add/Remove Programs. See tip 5 here.

Configuration all files with postgres 12 on centos:

step 1: search and edit file

sudo vi /var/lib/pgsql/12/data/pg_hba.conf

press "i" and at line IPv4 change

host    all             all             0.0.0.0/0            md5

step 2: search and edit file postgresql.conf

sudo vi /var/lib/pgsql/12/data/postgresql.conf

add last line: listen_addresses = '*' :wq! (save file) - step 3: restart

systemctl restart postgresql-12.service

app.use(path, middleware) is used to call middleware function that needs to be called before the route is hit for the corresponding path. Multiple middleware functions can be invoked via an app.use.

app.use(‘/fetch’, enforceAuthentication) -> enforceAuthentication middleware fn will be called when a request starting with ‘/fetch’ is received. It can be /fetch/users, /fetch/ids/{id}, etc

Some middleware functions might have to be called irrespective of the request. For such cases, a path is not specified, and since the the path defaults to / and every request starts with /, this middleware function will be called for all requests.

app.use(() => { // Initialize a common service })

next() fn needs to be called within each middleware function when multiple middleware functions are passed to app.use, else the next middleware function won’t be called.

reference : http://expressjs.com/en/api.html#app.use

Note: The documentation says we can bypass middleware functions following the current one by calling next('route') within the current middleware function, but this technique didn't work for me within app.use but did work with app.METHOD like below. So, fn1 and fn2 were called but not fn3.

app.get('/fetch', function fn1(req, res, next)  {
    console.log("First middleware function called"); 
        next();
    }, 
    function fn2(req, res, next) {
        console.log("Second middleware function called"); 
        next("route");
    }, 
    function fn3(req, res, next) {
        console.log("Third middleware function will not be called"); 
        next();
    })

Why not just load the frame off screen or hidden and then display it once it has finished loading. You could show a loading icon in its place to begin with to give the user immediate feedback that it's loading.

int op = 0;
string in = string.Empty;
do
{
    Console.WriteLine("enter choice");
    in = Console.ReadLine();
} while (!int.TryParse(in, out op));

What kind of field is this? The IN operator cannot be used with a single field, but is meant to be used in subqueries or with predefined lists:

-- subquery
SELECT a FROM x WHERE x.b NOT IN (SELECT b FROM y);
-- predefined list
SELECT a FROM x WHERE x.b NOT IN (1, 2, 3, 6);

If you are searching a string, go for the LIKE operator (but this will be slow):

-- Finds all rows where a does not contain "text"
SELECT * FROM x WHERE x.a NOT LIKE '%text%';

If you restrict it so that the string you are searching for has to start with the given string, it can use indices (if there is an index on that field) and be reasonably fast:

-- Finds all rows where a does not start with "text"
SELECT * FROM x WHERE x.a NOT LIKE 'text%';

Try using regular expressions: String.matches

Vanilla JS, without jQuery:

document.querySelector('#message span').innerHTML = 'hello world!'

The following ways work.

// The old way of using ParameterizedThreadStart. This requires a
// method which takes ONE object as the parameter so you need to
// encapsulate the parameters inside one object.
Thread t = new Thread(new ParameterizedThreadStart(StartupA));
t.Start(new MyThreadParams(path, port));

// You can also use an anonymous delegate to do this.
Thread t2 = new Thread(delegate()
{
    StartupB(port, path);
});
t2.Start();

// Or lambda expressions if you are using C# 3.0
Thread t3 = new Thread(() => StartupB(port, path));
t3.Start();

The Startup methods have following signature for these examples.

public void StartupA(object parameters);

public void StartupB(int port, string path);

// you need to have a list of data that you want the spinner to display
List<String> spinnerArray =  new ArrayList<String>();
spinnerArray.add("item1");
spinnerArray.add("item2");

ArrayAdapter<String> adapter = new ArrayAdapter<String>(
    this, android.R.layout.simple_spinner_item, spinnerArray);

adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
Spinner sItems = (Spinner) findViewById(R.id.spinner1);
sItems.setAdapter(adapter);

also to find out what is selected you could do something like this

String selected = sItems.getSelectedItem().toString();
if (selected.equals("what ever the option was")) {
}

If you are using 'docker-compose' as the method to spin up your container(s), there is actually a useful way to pass an environment variable defined on your server to the Docker container.

In your docker-compose.yml file, let's say you are spinning up a basic hapi-js container and the code looks like:

hapi_server:
  container_name: hapi_server
  image: node_image
  expose:
    - "3000"

Let's say that the local server that your docker project is on has an environment variable named 'NODE_DB_CONNECT' that you want to pass to your hapi-js container, and you want its new name to be 'HAPI_DB_CONNECT'. Then in the docker-compose.yml file, you would pass the local environment variable to the container and rename it like so:

hapi_server:
  container_name: hapi_server
  image: node_image
  environment:
    - HAPI_DB_CONNECT=${NODE_DB_CONNECT}
  expose:
    - "3000"

I hope this helps you to avoid hard-coding a database connect string in any file in your container!

Note that this issue can also occur if the domain you are referencing goes down (EG. no longer exists.)

The Jenkins EnvInject Plugin might be able to help you. It allows injecting environment variables into the build environment.

I know it has some ability to do scripting, so it might be able to do what you want. I have only used it to set simple properties (e.g. "LOG_PATH=${WORKSPACE}\logs").

Kernel resides in OS.Actually it is a memory space specially provided for handling the os functions.Some even say OS handles Resources of system and Kernel is one which is heart of os and maintain,manage i.e.keep track of os.

UPDATE: Turned my solution into a stand-alone python script.

This solution has saved me more than once. Hopefully others find it useful. This python script will find any jupyter kernel using more than cpu_threshold CPU and prompts the user to send a SIGINT to the kernel (KeyboardInterrupt). It will keep sending SIGINT until the kernel's cpu usage goes below cpu_threshold. If there are multiple misbehaving kernels it will prompt the user to interrupt each of them (ordered by highest CPU usage to lowest). A big thanks goes to gcbeltramini for writing code to find the name of a jupyter kernel using the jupyter api. This script was tested on MACOS with python3 and requires jupyter notebook, requests, json and psutil.

Put the script in your home directory and then usage looks like:

python ~/interrupt_bad_kernels.py
Interrupt kernel chews cpu.ipynb; PID: 57588; CPU: 2.3%? (y/n) y

Script code below:

from os import getpid, kill
from time import sleep
import re
import signal

from notebook.notebookapp import list_running_servers
from requests import get
from requests.compat import urljoin
import ipykernel
import json

    for pid in pids:
        if pid == my_pid:
            continue
        try:
            p = psutil.Process(pid)
            cmd = p.cmdline()
            for arg in cmd:
                if arg.count('ipykernel'):
                    cpu = p.cpu_percent(interval=0.1)
                    if cpu > cpu_threshold:
                        active_kernels.append((cpu, pid, cmd))

        for nn in json.loads(response.text):
            for kernel in active_kernels:
                for arg in kernel[-1]:
                    if arg.count(nn['kernel']['id']):

                        if interrupt.lower() == 'y':
                            p = psutil.Process(pid)
                            while p.cpu_percent(interval=0.1) > cpu_threshold:
                                kill(pid, signal.SIGINT)

The results are ordered by the first column, then the second, and so on for as many columns as the ORDER BY clause includes. If you want any results sorted in descending order, your ORDER BY clause must use the DESC keyword directly after the name or the number of the relevant column.

Check out this Example

SELECT first_name, last_name, hire_date, salary 
FROM employee 
ORDER BY hire_date DESC,last_name ASC;

It will order in succession. Order the Hire_Date first, then LAST_NAME it by Hire_Date .

What I usually do is supply the path to the executable explicitly:

EXE=./bin/
...
test all:
    $(EXE)x

I also use this technique to run non-native binaries under an emulator like QEMU if I'm cross compiling:

EXE = qemu-mips ./bin/

If make is using the sh shell, this should work:

test all:
    PATH=bin:$PATH x

std::string str;
char* const s = "test";

str.assign(s);

string& assign (const char* s); => signature FYR

Reference/s here.

Here is another illustrative example:

>>> print(", ".join(["ha" if i else "Ha" for i in range(3)]) + "!")
Ha, ha, ha!

It exploits the fact that if i evaluates to False for 0 and to True for all other values generated by the function range(). Therefore the list comprehension evaluates as follows:

>>> ["ha" if i else "Ha" for i in range(3)]
['Ha', 'ha', 'ha']

It is possible to connect to the database without specifying a password. Once you've done that you can then reset the passwords. I'm assuming that you've installed the database on your machine; if not you'll first need to connect to the machine the database is running on.

1. Ensure your user account is a member of the dba group. How you do this depends on what OS you are running.

2. Enter sqlplus / as sysdba in a Command Prompt/shell/Terminal window as appropriate. This should log you in to the database as SYS.

3. Once you're logged in, you can then enter

   alter user SYS identified by "newpassword";
   

   to reset the SYS password, and similarly for SYSTEM.

(Note: I haven't tried any of this on Oracle 12c; I'm assuming they haven't changed things since Oracle 11g.)

static means local for compilation unit (i.e. a single C++ source code file), or in other words it means it is not added to a global namespace. you can have multiple static variables in different c++ source code files with the same name and no name conflicts.

const is just constant, meaning can't be modified.

As described in this answer, you can easily create your own selector for hasText. This allows you to find the option with $('#test').find('option:hastText("B")').val();

Here's the hasText method I added:

 if( ! $.expr[':']['hasText'] ) {
     $.expr[':']['hasText'] = function( node, index, props ) {
       var retVal = false;
       // Verify single text child node with matching text
       if( node.nodeType == 1 && node.childNodes.length == 1 ) {
         var childNode = node.childNodes[0];
         retVal = childNode.nodeType == 3 && childNode.nodeValue === props[3];
       }
       return retVal;
     };
  }

You can put in in a paragraph

<p style="text-align:center;"><a href="contact.html" class="button large hpbottom">Get Started</a></p>

To align a div in the center, you have to do 2 things: - Make the div a fixed width - Set the left and right margin properties variable

<div class="container">
 <div style="width:100px; margin:0 auto;">
     <span>a centered div</span>
  </div>
</div>

This change only first handle in multihandle slider. In apiDoc you can see:"For example, if you specify values: [ 1, 5, 18 ] and create one custom handle, the plugin will create the other two."

If you need fixed size types, use types like uint32_t (unsigned integer 32 bits) defined in stdint.h. They are specified in C99.

You'd need to be careful as onBlur has some caveats in IE11 (How to use relatedTarget (or equivalent) in IE?, https://developer.mozilla.org/en-US/docs/Web/API/MouseEvent/relatedTarget).

There is, however, no way to use onFocusOut in React as far as I can tell. See the issue on their github https://github.com/facebook/react/issues/6410 if you need more information.

SimpleDateFormat parseFormat = new SimpleDateFormat("hh:mm a"); 

provided by Bart Kiers answer should be replaced with somethig like

SimpleDateFormat parseFormat = new SimpleDateFormat("hh:mm a",Locale.UK);

update q
set q.QuestionID = a.QuestionID
from QuestionTrackings q
inner join QuestionAnswers a
on q.AnswerID = a.AnswerID
where q.QuestionID is null -- and other conditions you might want

I recommend to check what the result set to update is before running the update (same query, just with a select):

select *
from QuestionTrackings q
inner join QuestionAnswers a
on q.AnswerID = a.AnswerID
where q.QuestionID is null -- and other conditions you might want

Particularly whether each answer id has definitely only 1 associated question id.
