Programs & Examples On #Lifted operators

This date function below achieves the desired effect without an additional script library. Basically it's just a simple date component concatenation in the right format, and augmenting of the Date object's prototype.

 Date.prototype.dateToISO8601String  = function() {
    var padDigits = function padDigits(number, digits) {
        return Array(Math.max(digits - String(number).length + 1, 0)).join(0) + number;
    }
    var offsetMinutes = this.getTimezoneOffset();
    var offsetHours = offsetMinutes / 60;
    var offset= "Z";    
    if (offsetHours < 0)
      offset = "-" + padDigits(offsetHours.replace("-","") + "00",4);
    else if (offsetHours > 0) 
      offset = "+" + padDigits(offsetHours  + "00", 4);

    return this.getFullYear() 
            + "-" + padDigits((this.getUTCMonth()+1),2) 
            + "-" + padDigits(this.getUTCDate(),2) 
            + "T" 
            + padDigits(this.getUTCHours(),2)
            + ":" + padDigits(this.getUTCMinutes(),2)
            + ":" + padDigits(this.getUTCSeconds(),2)
            + "." + padDigits(this.getUTCMilliseconds(),2)
            + offset;

}

Date.dateFromISO8601 = function(isoDateString) {
      var parts = isoDateString.match(/\d+/g);
      var isoTime = Date.UTC(parts[0], parts[1] - 1, parts[2], parts[3], parts[4], parts[5]);
      var isoDate = new Date(isoTime);
      return isoDate;       
}

function test() {
    var dIn = new Date();
    var isoDateString = dIn.dateToISO8601String();
    var dOut = Date.dateFromISO8601(isoDateString);
    var dInStr = dIn.toUTCString();
    var dOutStr = dOut.toUTCString();
    console.log("Dates are equal: " + (dInStr == dOutStr));
}

Usage:

var d = new Date();
console.log(d.dateToISO8601String());

Hopefully this helps someone else.

EDIT

Corrected UTC issue mentioned in comments, and credit to Alex for the dateFromISO8601 function.

Sorry to pile on to an old item. I found partial answers to my questions here but had to do some work so I wanted to share my results for the next person.

I ended up using the same approach as the other contributors, but with a few tweaks to fix the following

1. Long text was covering the arrows in the other solutions
2. The image being used was a somewhat old and ugly up/down combo arrow.

The below will give you a working solution with the above issues fixed. Note: I used a white arrow for my use case, you may need to change the color of the arrow for yours.

here's a preview:

If it contains less than 3 slashes thus you've it got and if not then we can find the occurrence between it:

import re

link = http://forum.unisoftdev.com/something

slash_count = len(re.findall("/", link))
print slash_count # output: 3

if slash_count > 2:
   regex = r'\:\/\/(.*?)\/'
   pattern  = re.compile(regex)
   path = re.findall(pattern, url)

   print path

The question is correctly answered here Center a column using Twitter Bootstrap 3

For odd rows: i.e., col-md-7 or col-large-9 use this

Add col-centered to the column you want centered.

<div class="col-lg-11 col-centered">    

And add this to your stylesheet:

.col-centered{
float: none;
margin: 0 auto;
}

For even rows: i.e., col-md-6 or col-large-10 use this

Simply use bootstrap 3's offset col class. i.e.,

<div class="col-lg-10 col-lg-offset-1">

C++11 added alias declarations, which are generalization of typedef, allowing templates:

template <size_t N>
using Vector = Matrix<N, 1>;

The type Vector<3> is equivalent to Matrix<3, 1>.

In C++03, the closest approximation was:

template <size_t N>
struct Vector
{
    typedef Matrix<N, 1> type;
};

Here, the type Vector<3>::type is equivalent to Matrix<3, 1>.

I tried ng remove component Comp_Name also ng distroy component but it is not yet supported by angular so the best option for now is to manually remove it from the folder structure.

Use the method "getCenterCoordinate" to obtain the center coordinate and use in CameraPosition.

private void setUpMap() {
    mMap.setMyLocationEnabled(true);
    mMap.getUiSettings().setScrollGesturesEnabled(true);
    mMap.getUiSettings().setTiltGesturesEnabled(true);
    mMap.getUiSettings().setRotateGesturesEnabled(true);

    clientMarker = mMap.addMarker(new MarkerOptions()
            .position(new LatLng(Double.valueOf(-12.1024174), Double.valueOf(-77.0262274)))
            .icon(BitmapDescriptorFactory.fromResource(R.mipmap.ic_taxi))
    );
    clientMarker = mMap.addMarker(new MarkerOptions()
            .position(new LatLng(Double.valueOf(-12.1024637), Double.valueOf(-77.0242617)))
            .icon(BitmapDescriptorFactory.fromResource(R.mipmap.ic_location))
    );

    camPos = new CameraPosition.Builder()
            .target(getCenterCoordinate())
            .zoom(17)
            .build();
    camUpd3 = CameraUpdateFactory.newCameraPosition(camPos);
    mMap.animateCamera(camUpd3);
}


public LatLng getCenterCoordinate(){
    LatLngBounds.Builder builder = new LatLngBounds.Builder();
    builder.include(new LatLng(Double.valueOf(-12.1024174), Double.valueOf(-77.0262274)));
    builder.include(new LatLng(Double.valueOf(-12.1024637), Double.valueOf(-77.0242617)));
    LatLngBounds bounds = builder.build();
    return bounds.getCenter();
}

October 2019 - Ubuntu 18.04 on WSL with oh-my-zsh; the instructions here worked perfectly -

(first, install pre-requisites using sudo apt-get install build-essential curl file git)

finally create a ~/.zprofile with the following contents: emulate sh -c '. ~/.profile'

Learn them and slowly you'll be able to reconize and figure out when to use them. Start with something simple as the singleton pattern :)

if you want to create one instance of an object and just ONE. You use the singleton pattern. Let's say you're making a program with an options object. You don't want several of those, that would be silly. Singleton makes sure that there will never be more than one. Singleton pattern is simple, used a lot, and really effective.

Create a plain text file (using notepad) and type the exact line you would use to run your Java file with the command prompt. Then change the extension to .bat and you're done.

Double clicking on this file would run your java program.

I reccommend one file for javac, one for java so you can troubleshoot if anything is wrong.

• Make sure java is in your path, too.. IE typing java in a Dos windows when in your java workspace should bring up the java version message. If java is not in your path the batch file won't work unless you use absolut path to the java binary.

Did you setup your project to be compiled with 1.4 compliance? If so, do what krock said. Or to be more exact you need to select the J2SE-1.4 execution environment and check one of the installed JRE that you want to use in 1.4 compliance mode; most likely you'll have a 1.6 JRE installed, just check that one. Or install a 1.4 JRE if you have a setup kit, and use that one.

Otherwise go to your Eclipse preferences, Java -> Compiler and check if the compliance is set to 1.4. If it is change it back to 1.6. If it's not go to the project properties, and check if it has project specific settings. Go to Java Compiler, and uncheck that if you want to use the general eclipse preferences. Or set the project specific settings to 1.6, so that it's always 1.6 regardless of eclipse preferences.

Now only I came across this situation and found some more interesting features around GROUP_CONCAT. I hope these details will make you feel interesting.

simple GROUP_CONCAT

SELECT GROUP_CONCAT(TaskName) 
FROM Tasks;

Result:

+------------------------------------------------------------------+
| GROUP_CONCAT(TaskName)                                           |
+------------------------------------------------------------------+
| Do garden,Feed cats,Paint roof,Take dog for walk,Relax,Feed cats |
+------------------------------------------------------------------+

GROUP_CONCAT with DISTINCT

SELECT GROUP_CONCAT(TaskName) 
FROM Tasks;

Result:

+------------------------------------------------------------------+
| GROUP_CONCAT(TaskName)                                           |
+------------------------------------------------------------------+
| Do garden,Feed cats,Paint roof,Take dog for walk,Relax,Feed cats |
+------------------------------------------------------------------+

GROUP_CONCAT with DISTINCT and ORDER BY

SELECT GROUP_CONCAT(DISTINCT TaskName ORDER BY TaskName DESC) 
FROM Tasks;

Result:

+--------------------------------------------------------+
| GROUP_CONCAT(DISTINCT TaskName ORDER BY TaskName DESC) |
+--------------------------------------------------------+
| Take dog for walk,Relax,Paint roof,Feed cats,Do garden |
+--------------------------------------------------------+

GROUP_CONCAT with DISTINCT and SEPARATOR

SELECT GROUP_CONCAT(DISTINCT TaskName SEPARATOR ' + ') 
FROM Tasks;

Result:

+----------------------------------------------------------------+
| GROUP_CONCAT(DISTINCT TaskName SEPARATOR ' + ')                |
+----------------------------------------------------------------+
| Do garden + Feed cats + Paint roof + Relax + Take dog for walk |
+----------------------------------------------------------------+

GROUP_CONCAT and Combining Columns

SELECT GROUP_CONCAT(TaskId, ') ', TaskName SEPARATOR ' ') 
FROM Tasks;

Result:

+------------------------------------------------------------------------------------+
| GROUP_CONCAT(TaskId, ') ', TaskName SEPARATOR ' ')                                 |
+------------------------------------------------------------------------------------+
| 1) Do garden 2) Feed cats 3) Paint roof 4) Take dog for walk 5) Relax 6) Feed cats |
+------------------------------------------------------------------------------------+

GROUP_CONCAT and Grouped Results Assume that the following are the results before using GROUP_CONCAT

You could set an interceptor "ClientHttpRequestInterceptor" in your RestTemplate to avoid setting the header every time you send a request.

public class HeaderRequestInterceptor implements ClientHttpRequestInterceptor {

        private final String headerName;

        private final String headerValue;

        public HeaderRequestInterceptor(String headerName, String headerValue) {
            this.headerName = headerName;
            this.headerValue = headerValue;
        }

        @Override
        public ClientHttpResponse intercept(HttpRequest request, byte[] body, ClientHttpRequestExecution execution) throws IOException {
            request.getHeaders().set(headerName, headerValue);
            return execution.execute(request, body);
        }
    }

Then

List<ClientHttpRequestInterceptor> interceptors = new ArrayList<ClientHttpRequestInterceptor>();
interceptors.add(new HeaderRequestInterceptor("Accept", MediaType.APPLICATION_JSON_VALUE));

RestTemplate restTemplate = new RestTemplate();
restTemplate.setInterceptors(interceptors);

I'm looking at a similar problem, and I've found some of the best references come from chemistry (from peaks finding in mass-spec data). For a good thorough review of peaking finding algorithms read this. This is one of the best clearest reviews of peak finding techniques that I've run across. (Wavelets are the best for finding peaks of this sort in noisy data.).

It looks like your peaks are clearly defined and aren't hidden in the noise. That being the case I'd recommend using smooth savtizky-golay derivatives to find the peaks (If you just differentiate the data above you'll have a mess of false positives.). This is a very effective technique and is pretty easy to implemented (you do need a matrix class w/ basic operations). If you simply find the zero crossing of the first S-G derivative I think you'll be happy.

In .NET System.String (aka string) is a immutable object. That means when you create an object you can not change it's value afterwards. You can only recreate a immutable object.

System.Text.StringBuilder is mutable equivalent of System.String and you can chane its value

For Example:

class Program
{
    static void Main(string[] args)
    {

        System.String str = "inital value";
        str = "\nsecond value";
        str = "\nthird value";

        StringBuilder sb = new StringBuilder();
        sb.Append("initial value");
        sb.AppendLine("second value");
        sb.AppendLine("third value");
    }
}

Generates following MSIL : If you investigate the code. You will see that whenever you chane an object of System.String you are actually creating new one. But in System.Text.StringBuilder whenever you change the value of text you dont recreate the object.

.method private hidebysig static void  Main(string[] args) cil managed
{
  .entrypoint
  // Code size       62 (0x3e)
  .maxstack  2
  .locals init ([0] string str,
           [1] class [mscorlib]System.Text.StringBuilder sb)
  IL_0000:  nop
  IL_0001:  ldstr      "inital value"
  IL_0006:  stloc.0
  IL_0007:  ldstr      "\nsecond value"
  IL_000c:  stloc.0
  IL_000d:  ldstr      "\nthird value"
  IL_0012:  stloc.0
  IL_0013:  newobj     instance void [mscorlib]System.Text.StringBuilder::.ctor()
  IL_0018:  stloc.1
  IL_0019:  ldloc.1
  IL_001a:  ldstr      "initial value"
  IL_001f:  callvirt   instance class [mscorlib]System.Text.StringBuilder [mscorlib]System.Text.StringBuilder::Append(string)
  IL_0024:  pop
  IL_0025:  ldloc.1
  IL_0026:  ldstr      "second value"
  IL_002b:  callvirt   instance class [mscorlib]System.Text.StringBuilder [mscorlib]System.Text.StringBuilder::AppendLine(string)
  IL_0030:  pop
  IL_0031:  ldloc.1
  IL_0032:  ldstr      "third value"
  IL_0037:  callvirt   instance class [mscorlib]System.Text.StringBuilder [mscorlib]System.Text.StringBuilder::AppendLine(string)
  IL_003c:  pop
  IL_003d:  ret
} // end of method Program::Main

because:

Static : as we can't have objects of interfaces so we should avoid using Object level member variables and should use class level variables i.e. static.

Final : so that we should not have ambiguous values for the variables(Diamond problem - Multiple Inheritance).

And as per the documentation interface is a contract and not an implementation.

reference: Abhishek Jain's answer on quora

Have a look at CASE statements
http://msdn.microsoft.com/en-us/library/ms181765.aspx

<ItemTemplate>
     <asp:Button ID="Button1" runat="server" Text="Button" 
            OnClick="MyButtonClick" />
</ItemTemplate>

and your method

 protected void MyButtonClick(object sender, System.EventArgs e)
{
     //Get the button that raised the event
Button btn = (Button)sender;

    //Get the row that contains this button
GridViewRow gvr = (GridViewRow)btn.NamingContainer;
}

I use:

ls -d */ | cut -f1 -d'/'

This creates a single column without a trailing slash - useful in scripts.

Connection in WebConfig

Add the your connection string to the <connectionStrings> element in the Web.config file.

<connectionStrings>
<add name="ConnectionString" connectionString="Data Source=192.168.1.25;Initial Catalog=Login;Persist Security Info=True;User ID=sa;Password=example.com"   providerName="System.Data.SqlClient" />
</connectionStrings>

In Class.Cs

public static string ConnectionString{
get{
return ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;}
set{}

It is now possible with the HTML5 webapp manifest. See below.

Original answer:

You can't lock a website or a web application in a specific orientation. It goes against the natural behaviour of the device.

You can detect the device orientation with CSS3 media queries like this:

@media screen and (orientation:portrait) {
    // CSS applied when the device is in portrait mode
}

@media screen and (orientation:landscape) {
    // CSS applied when the device is in landscape mode
}

Or by binding a JavaScript orientation change event like this:

document.addEventListener("orientationchange", function(event){
    switch(window.orientation) 
    {  
        case -90: case 90:
            /* Device is in landscape mode */
            break; 
        default:
            /* Device is in portrait mode */
    }
});

Update on November 12, 2014: It is now possible with the HTML5 webapp manifest.

As explained on html5rocks.com, you can now force the orientation mode using a manifest.json file.

You need to include those line into the json file:

{
    "display":      "standalone", /* Could be "fullscreen", "standalone", "minimal-ui", or "browser" */
    "orientation":  "landscape", /* Could be "landscape" or "portrait" */

And you need to include the manifest into your html file like this:

<link rel="manifest" href="manifest.json">

Not exactly sure what the support is on the webapp manifest for locking orientation mode, but Chrome is definitely there. Will update when I have the info.

Several answers here use range. xrange is generally better as it returns a generator, rather than a fully-instantiated list. Where memory and or iterables of widely-varying lengths can be an issue, xrange is superior.

This also can be happened due to wrong user name or password. As solutions I've added allowPublicKeyRetrieval=true&useSSL=false part but still I got error then I checked the password and it was wrong.

I have found following way to fix this issue... I hope this can help you.

json_encode($data,JSON_UNESCAPED_UNICODE|JSON_UNESCAPED_SLASHES);

For your first method change ws.Range("A") to ws.Range("A:A") which will search the entirety of column a, like so:

Sub Find_Bingo()

        Dim wb As Workbook
        Dim ws As Worksheet
        Dim FoundCell As Range
        Set wb = ActiveWorkbook
        Set ws = ActiveSheet

            Const WHAT_TO_FIND As String = "Bingo"

            Set FoundCell = ws.Range("A:A").Find(What:=WHAT_TO_FIND)
            If Not FoundCell Is Nothing Then
                MsgBox (WHAT_TO_FIND & " found in row: " & FoundCell.Row)
            Else
                MsgBox (WHAT_TO_FIND & " not found")
            End If
End Sub

For your second method, you are using Bingo as a variable instead of a string literal. This is a good example of why I add Option Explicit to the top of all of my code modules, as when you try to run the code it will direct you to this "variable" which is undefined and not intended to be a variable at all.

Additionally, when you are using With...End With you need a period . before you reference Cells, so Cells should be .Cells. This mimics the normal qualifying behavior (i.e. Sheet1.Cells.Find..)

Change Bingo to "Bingo" and change Cells to .Cells

With Sheet1
        Set FoundCell = .Cells.Find(What:="Bingo", After:=.Cells(1, 1), _
        LookIn:=xlValues, lookat:=xlPart, SearchOrder:=xlByRows, _
        SearchDirection:=xlNext, MatchCase:=False, SearchFormat:=False)
    End With

If Not FoundCell Is Nothing Then
        MsgBox ("""Bingo"" found in row " & FoundCell.Row)
Else
        MsgBox ("Bingo not found")
End If

Update

In my

With Sheet1
    .....
End With

The Sheet1 refers to a worksheet's code name, not the name of the worksheet itself. For example, say I open a new blank Excel workbook. The default worksheet is just Sheet1. I can refer to that in code either with the code name of Sheet1 or I can refer to it with the index of Sheets("Sheet1"). The advantage to using a codename is that it does not change if you change the name of the worksheet.

Continuing this example, let's say I renamed Sheet1 to Data. Using Sheet1 would continue to work, as the code name doesn't change, but now using Sheets("Sheet1") would return an error and that syntax must be updated to the new name of the sheet, so it would need to be Sheets("Data").

In the VB Editor you would see something like this:

Notice how, even though I changed the name to Data, there is still a Sheet1 to the left. That is what I mean by codename.

The Data worksheet can be referenced in two ways:

Debug.Print Sheet1.Name
Debug.Print Sheets("Data").Name

Both should return Data

More discussion on worksheet code names can be found here.

Try this function...

function calculate_age(birth_month,birth_day,birth_year)
{
    today_date = new Date();
    today_year = today_date.getFullYear();
    today_month = today_date.getMonth();
    today_day = today_date.getDate();
    age = today_year - birth_year;

    if ( today_month < (birth_month - 1))
    {
        age--;
    }
    if (((birth_month - 1) == today_month) && (today_day < birth_day))
    {
        age--;
    }
    return age;
}

OR

function getAge(dateString) 
{
    var today = new Date();
    var birthDate = new Date(dateString);
    var age = today.getFullYear() - birthDate.getFullYear();
    var m = today.getMonth() - birthDate.getMonth();
    if (m < 0 || (m === 0 && today.getDate() < birthDate.getDate())) 
    {
        age--;
    }
    return age;
}

See Demo.

In python add the following lines to get a time stamp:

>>> import time
>>> time.time()
1335906993.995389
>>> int(time.time())
1335906993

Thanks, finally got an solution to not put utf8::encode all over code. To synthesize and complete for other cases, like write and read files in utf8 and also works with LoadFile of an YAML file in utf8

use utf8;
use open ':encoding(utf8)';
binmode(STDOUT, ":utf8");

open(FH, ">test.txt"); 
print FH "something éá";

use YAML qw(LoadFile Dump);
my $PUBS = LoadFile("cache.yaml");
my $f = "2917";
my $ref = $PUBS->{$f};
print "$f \"".$ref->{name}."\" ". $ref->{primary_uri}." ";

where cache.yaml is:

---
2917:
  id: 2917
  name: Semanário
  primary_uri: 2917.xml

You probably want to round the double to 5 decimals or so before comparing since a double can contain very small decimal parts if you have done some calculations with it.

double d = 10.0;
d /= 3.0; // d should be something like 3.3333333333333333333333...
d *= 3.0; // d is probably something like 9.9999999999999999999999...

// d should be 10.0 again but it is not, so you have to use rounding before comparing

d = myRound(d, 5); // d is something like 10.00000
if (fmod(d, 1.0) == 0)
  // No decimals
else
  // Decimals

If you are using C++ i don't think there is a round-function, so you have to implement it yourself like in: http://www.cplusplus.com/forum/general/4011/

You can use this command (python script) for larger inputs:

echo 58595a | python -c "import sys; import binascii; print(binascii.unhexlify(sys.stdin.read().strip()).decode())"

The result will be:

XYZ

And for more simplicity, define an alias:

alias hexdecoder='python -c "import sys; import binascii; print(binascii.unhexlify(sys.stdin.read().strip()).decode())"'

echo 58595a | hexdecoder

This is what I did to integrate Identity with an existing database.

1. Create a sample MVC project with MVC template. This has all the code needed for Identity implementation - Startup.Auth.cs, IdentityConfig.cs, Account Controller code, Manage Controller, Models and related views.

2. Install the necessary nuget packages for Identity and OWIN. You will get an idea by seeing the references in the sample Project and the answer by @Sam

3. Copy all these code to your existing project. Please note don't forget to add the "DefaultConnection" connection string for Identity to map to your database. Please check the ApplicationDBContext class in IdentityModel.cs where you will find the reference to "DefaultConnection" connection string.

4. This is the SQL script I ran on my existing database to create necessary tables:

5. Check and solve any remaining errors and you are done. Identity will handle the rest :)

add a condition to check for the admin directory, something like:

RewriteCond %{REQUEST_URI} !^/?(admin|user)/
RewriteRule ^([^/] )/([^/] )\.html$ index.php?lang=$1&mod=$2 [L]

RewriteCond %{REQUEST_URI} !^/?(admin|user)/
RewriteRule ^([^/] )/$ index.php?lang=$1&mod=home [L]

My problem was in Manifiest file. I have deleted launcher icons and did not reference the new ones on Manifiest :)

A closure is a function that has access to information from the environment it was defined in.

For some, the information is the value in the environment at the time of creation. For others, the information is the variables in the environment at the time of creation.

If the lexical environment that the closure refers to belongs to a function that has exited, then (in the case of a closure referring to the variables in the environment) those lexical variables will continue to exist for reference by the closure.

A closure can be thought of a special case of global variables -- with a private copy created just for the function.

Or it can be thought of as a method where the environment is a specific instance of an object whose properties are the variables in the environment.

The former (closure as environment) similar to the latter where the environment copy is a context variable passed to each function in the former, and the instance variables form a context variable in the latter.

So a closure is a way to call a function without having to specify the context explicitly as a parameter or as the object in a method invocation.

var closure = createclosure(varForClosure);
closure(param1);  // closure has access to whatever createclosure gave it access to,
                  // including the parameter storing varForClosure.

vs

var contextvar = varForClosure; // use a struct for storing more than one..
contextclosure(contextvar, param1);

vs

var contextobj = new contextclass(varForClosure);
contextobj->objclosure(param1);

For maintainable code, I recommend the object oriented way. However for a quick and easy set of tasks (for example creating a callback), a closure can become natural and more clear, especially in the context of lamda or anonymous functions.

Your divider may not be showing due to too large dividerPadding. You set 22dip, that means the divider is truncated by 22dip from top and by 22dip from bottom. If your layout height is less than or equal 44dip then no divider is visible.

I just had the same error with Visual Studio 2013 and EF6. I had to use a NewGet packed Entity Framework and done the job perfectly

I answered a very similar question:

https://stackoverflow.com/a/15982217/1467082

You simply need to iterate over the series' .Points collection, and then you can assign the points' .Format.Fill.ForeColor.RGB value based on whatever criteria you need.

UPDATED

The code below will color the chart per the screenshot. This only assumes three colors are used. You can add additional case statements for other color values, and update the assignment of myColor to the appropriate RGB values for each.

Option Explicit
Sub ColorScatterPoints()
    Dim cht As Chart
    Dim srs As Series
    Dim pt As Point
    Dim p As Long
    Dim Vals$, lTrim#, rTrim#
    Dim valRange As Range, cl As Range
    Dim myColor As Long

    Set cht = ActiveSheet.ChartObjects(1).Chart
    Set srs = cht.SeriesCollection(1)

   '## Get the series Y-Values range address:
    lTrim = InStrRev(srs.Formula, ",", InStrRev(srs.Formula, ",") - 1, vbBinaryCompare) + 1
    rTrim = InStrRev(srs.Formula, ",")
    Vals = Mid(srs.Formula, lTrim, rTrim - lTrim)
    Set valRange = Range(Vals)

    For p = 1 To srs.Points.Count
        Set pt = srs.Points(p)
        Set cl = valRange(p).Offset(0, 1) '## assume color is in the next column.

        With pt.Format.Fill
            .Visible = msoTrue
            '.Solid  'I commented this out, but you can un-comment and it should still work
            '## Assign Long color value based on the cell value
            '## Add additional cases as needed.
            Select Case LCase(cl)
                Case "red"
                    myColor = RGB(255, 0, 0)
                Case "orange"
                    myColor = RGB(255, 192, 0)
                Case "green"
                    myColor = RGB(0, 255, 0)
            End Select

            .ForeColor.RGB = myColor

        End With
    Next


End Sub

It was already pointed in this comment and in this answer, but I'll try to give a more direct answer to the question:

from IPython.display import display
import numpy as np
import pandas as pd

n = 100
foo = pd.DataFrame(index=range(n))
foo['floats'] = np.random.randn(n)

with pd.option_context("display.max_rows", foo.shape[0]):
    display(foo)

pandas.option_context is available since pandas 0.13.1 (pandas 0.13.1 release notes). According to this,

[it] allow[s] you to execute a codeblock with a set of options that revert to prior settings when you exit the with block.

Feel free to use my form sheet controller MZFormSheetControllerfor iPhone, in example project there are many examples on how to present modal view controller which will not cover full window and has many presentation/transition styles.

You can also try newest version of MZFormSheetController which is called MZFormSheetPresentationController and have a lot of more features.

One way would be to just escape the quotes properly:

<input type="button" value="click" id="mybtn"
       onclick="myfunction('/myController/myAction', 
               'myfuncionOnOK(\'/myController2/myAction2\', 
                   \'myParameter2\');',
               'myfuncionOnCancel(\'/myController3/myAction3\', 
                   \'myParameter3\');');">

In this case, though, I think a better way to handle this would be to wrap the two handlers in anonymous functions:

<input type="button" value="click" id="mybtn"
       onclick="myfunction('/myController/myAction', 
                function() { myfuncionOnOK('/myController2/myAction2', 
                             'myParameter2'); },
                function() { myfuncionOnCancel('/myController3/myAction3', 
                             'myParameter3'); });">

And then, you could call them from within myfunction like this:

function myfunction(url, onOK, onCancel)
{
    // Do whatever myfunction would normally do...

    if (okClicked)
    {
        onOK();
    }

    if (cancelClicked)
    {
        onCancel();
    }
}

That's probably not what myfunction would actually look like, but you get the general idea. The point is, if you use anonymous functions, you have a lot more flexibility, and you keep your code a lot cleaner as well.

As mentioned before, [[NSDate date] timeIntervalSince1970] returns an NSTimeInterval, which is a duration in seconds, not milli-seconds.

You can visit https://currentmillis.com/ to see how you can get in the language you desire. Here is the list -

ActionScript    (new Date()).time

WScript.Echo DateDiff("s", "01/01/1970 00:00:00", Now()) * 1000 - offsetInMillis + Timer * 1000 mod 1000

For objective C I did something like below to print it -

long long mills = (long long)([[NSDate date] timeIntervalSince1970] * 1000.0);
 NSLog(@"Current date %lld", mills);

Hopw this helps.

To Fix The "Missing "server" JVM at C:\Program Files\Java\jre7\bin\server\jvm­­.dll, please install or use the JRE or JDK that contains these missing components.

Follow these steps:

Go to oracle.com and install Java JRE7 (Check if Java 6 is not installed already)

After that, go to C:/Program files/java/jre7/bin

Here, create an folder called Server

Now go into the C:/Program files/java/jre7/bin/client folder

Copy all the data in this folder into the new C:/Program files/java/jre7/bin/Server folder

I'm afraid that using map() method of an array may be expensive since entire array is to be iterated. Instead, I combine a new array that consists of three parts:

• head - items before the modified item
• the modified item
• tail - items after the modified item

Here the example I've used in my code (NgRx, yet the machanism is the same for other Redux implementations):

// toggle done property: true to false, or false to true

function (state, action) {
    const todos = state.todos;
    const todoIdx = todos.findIndex(t => t.id === action.id);

    const todoObj = todos[todoIdx];
    const newTodoObj = { ...todoObj, done: !todoObj.done };

    const head = todos.slice(0, todoIdx - 1);
    const tail = todos.slice(todoIdx + 1);
    const newTodos = [...head, newTodoObj, ...tail];
}

Another way of viewing the full content of the cells in a pandas dataframe is to use IPython's display functions:

from IPython.display import HTML

HTML(df.to_html())

To list any process listening to the port 8080:

lsof -i:8080

To kill any process listening to the port 8080:

kill $(lsof -t -i:8080)

or more violently:

kill -9 $(lsof -t -i:8080)

(-9 corresponds to the SIGKILL - terminate immediately/hard kill signal: see List of Kill Signals and What is the purpose of the -9 option in the kill command?. If no signal is specified to kill, the TERM signal a.k.a. -15 or soft kill is sent, which sometimes isn't enough to kill a process.).

If you only want to read the first 999,999 (non-header) rows:

read_csv(..., nrows=999999)

If you only want to read rows 1,000,000 ... 1,999,999

read_csv(..., skiprows=1000000, nrows=999999)

nrows : int, default None Number of rows of file to read. Useful for reading pieces of large files*

skiprows : list-like or integer Row numbers to skip (0-indexed) or number of rows to skip (int) at the start of the file

and for large files, you'll probably also want to use chunksize:

chunksize : int, default None Return TextFileReader object for iteration

First, create a directory(folder) in the root of your local repo that will contain the screenshots you want added. Let’s call the name of this directory screenshots. Place the images (JPEG, PNG, GIF,` etc) you want to add into this directory.

Android Studio Workspace Screenshot

Secondly, you need to add a link to each image into your README. So, if I have images named 1_ArtistsActivity.png and 2_AlbumsActivity.png in my screenshots directory, I will add their links like so:

 <img src="screenshots/1_ArtistsActivity.png" height="400" alt="Screenshot"/> <img src=“screenshots/2_AlbumsActivity.png" height="400" alt="Screenshot"/>

If you want each screenshot on a separate line, write their links on separate lines. However, it’s better if you write all the links in one line, separated by space only. It might actually not look too good but by doing so GitHub automatically arranges them for you.

Finally, commit your changes and push it!

To get a sticky footer:

1. Have a <div> with class="wrapper" for your content.

2. Right before the closing </div> of the wrapper place the <div class="push"></div>.

3. Right after the closing </div> of the wrapper place the <div class="footer"></div>.

* {
    margin: 0;
}
html, body {
    height: 100%;
}
.wrapper {
    min-height: 100%;
    height: auto !important;
    height: 100%;
    margin: 0 auto -142px; /* the bottom margin is the negative value of the footer's height */
}
.footer, .push {
    height: 142px; /* .push must be the same height as .footer */
}

make_unique is an upcoming C++14 feature and thus might not be available on your compiler, even if it is C++11 compliant.

You can however easily roll your own implementation:

template<typename T, typename... Args>
std::unique_ptr<T> make_unique(Args&&... args) {
    return std::unique_ptr<T>(new T(std::forward<Args>(args)...));
}

(FYI, here is the final version of make_unique that was voted into C++14. This includes additional functions to cover arrays, but the general idea is still the same.)

The first is the most concise, I would go with that. The first two are the same, but the first is just that little bit shorter, so you'll save on bytes. The third is plain wrong, because that condition will always evaluate true because the object will never be null or falsy for that matter.

Accepted answer is certainly a good solution, but here is the way I went about generating a CSV and serving it from a view.

Thought it was worth while putting this here as it took me a little bit of fiddling to get all the desirable behaviour (overwrite existing file, storing to the right spot, not creating duplicate files etc).

Django 1.4.1

Python 2.7.3

#Model
class MonthEnd(models.Model):
    report = models.FileField(db_index=True, upload_to='not_used')

import csv
from os.path import join

#build and store the file
def write_csv():
    path = join(settings.MEDIA_ROOT, 'files', 'month_end', 'report.csv')
    f = open(path, "w+b")

    #wipe the existing content
    f.truncate()

    csv_writer = csv.writer(f)
    csv_writer.writerow(('col1'))

    for num in range(3):
        csv_writer.writerow((num, ))

    month_end_file = MonthEnd()
    month_end_file.report.name = path
    month_end_file.save()

from my_app.models import MonthEnd

#serve it up as a download
def get_report(request):
    month_end = MonthEnd.objects.get(file_criteria=criteria)

    response = HttpResponse(month_end.report, content_type='text/plain')
    response['Content-Disposition'] = 'attachment; filename=report.csv'

    return response

I have tried the above answers and the best i think is this one

@item.First_Name.Substring(0,1)

In this i could get the first letter of the string

From Artima's Typing: Strong vs. Weak, Static vs. Dynamic article:

strong typing prevents mixing operations between mismatched types. In order to mix types, you must use an explicit conversion

weak typing means that you can mix types without an explicit conversion

In the Pascal Costanza's paper, Dynamic vs. Static Typing — A Pattern-Based Analysis (PDF), he claims that in some cases, static typing is more error-prone than dynamic typing. Some statically typed languages force you to manually emulate dynamic typing in order to do "The Right Thing". It's discussed at Lambda the Ultimate.

For Custom Dialog:

just call super(context,R.style.<dialog style>) instead of super(context) in dialog constructor

public class MyDialog extends Dialog
{
    public MyDialog(Context context)
    {
       super(context, R.style.Theme_AppCompat_Light_Dialog_Alert)
    }
}

For AlertDialog:

Just create alertDialog with this constructor:

 new AlertDialog.Builder(
 new ContextThemeWrapper(context, android.R.style.Theme_Dialog))

#include<iostream>
using namespace std;

class A
{
    public:
        struct Assign
        {
            public:
                int a=10;
                float b=20.5;
            private:
                double c=30.0;
                long int d=40;
         };
         struct Assign ALT;
};

class B: public A
{
public:
    int x = 10;
private:
    float y = 20.8;
};

int main()
{
   B myobj;
   A obj;
   //cout<<myobj.a<<endl;
   //cout<<myobj.b<<endl;
   //cout<<obj.a<<endl;
   //cout<<obj.b<<endl;
   cout<<myobj.ALT.a<<endl;

    return 0;
}

    enter code here

None of the solutions above worked for dynamic that comes from Json, I however managed to transform one with Try catch (by @user3359453) by changing exception type thrown (KeyNotFoundException instead of RuntimeBinderException) into something that actually works...

public static bool HasProperty(dynamic obj, string name)
    {
        try
        {
            var value = obj[name];
            return true;
        }
        catch (KeyNotFoundException)
        {
            return false;
        }
    }

Hope this saves you some time.

As @ J_F answered in the comments, using {r echo = T, results = 'hide'}.

I wanted to expand on their answer - there are great resources you can access to determine all possible options for your chunk and output display - I keep a printed copy at my desk!

You can find them either on the RStudio Website under Cheatsheets (look for the R Markdown cheatsheet and R Markdown Reference Guide) or, in RStudio, navigate to the "Help" tab, choose "Cheatsheets", and look for the same documents there.

Finally to set default chunk options, you can run (in your first chunk) something like the following code if you want most chunks to have the same behavior:

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = T,
                      results = "hide")
```

Later, you can modify the behavior of individual chunks like this, which will replace the default value for just the results option.

```{r analysis, results="markup"}
# code here
```

With no additional plugin required, this bootstrap solution works great for me:

<div style="position:relative;">
        <a class='btn btn-primary' href='javascript:;'>
            Choose File...
            <input type="file" style='position:absolute;z-index:2;top:0;left:0;filter: alpha(opacity=0);-ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";opacity:0;background-color:transparent;color:transparent;' name="file_source" size="40"  onchange='$("#upload-file-info").html($(this).val());'>
        </a>
        &nbsp;
        <span class='label label-info' id="upload-file-info"></span>
</div>

if you're using Aqua Data studio, simply write select * from table_name and instead of pressing execute,, press ctrl +D .

You shall be able to see the description for the table

Use:

sed -n '1d;p'

This command will delete the first line and print the rest.

Use Controls object

For i = 1 To X
    Controls("Label" & i).Caption =  MySheet.Cells(i + 1, i).Value
Next

Yes. You can tell the OS what kind of transition you want to have for your activity.

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

    ...

}

Where ANIMATION is an integer referring to a built in animation in the OS.

Right click on project -> Run As -> Run Configurations..-> Select Arguments tab -> In VM Arguments you can increase your JVM memory allocation. Java HotSpot document will help you to setup your VM Argument HERE

I will not prefer to make any changes into eclipse.ini as minor mistake cause lot of issues. It's easier to play with VM Args

You could do below:

select
iif ( OpeningBalance>=0 And OpeningBalance<=500 , 20, 

                  iif ( OpeningBalance>=5001 And OpeningBalance<=10000 , 30, 

                       iif ( OpeningBalance>=10001 And OpeningBalance<=20000 , 40, 

50 ) ) ) as commission
from table

From the man read:

#include <unistd.h>
ssize_t read(int fd, void *buf, size_t count);

Input parameters:

• int fd file descriptor is an integer and not a file pointer. The file descriptor for stdin is 0

• void *buf pointer to buffer to store characters read by the read function

• size_t count maximum number of characters to read

So you can read character by character with the following code:

char buf[1];

while(read(0, buf, sizeof(buf))>0) {
   // read() here read from stdin charachter by character
   // the buf[0] contains the character got by read()
   ....
}

There are few modes to open file (read, write etc..)

If you want to read from file you should type file = open("File.txt","r"), if write than file = open("File.txt","w"). You need to give the right permission regarding your usage.

more modes:

• r. Opens a file for reading only.
• rb. Opens a file for reading only in binary format.
• r+ Opens a file for both reading and writing.
• rb+ Opens a file for both reading and writing in binary format.
• w. Opens a file for writing only.
• you can find more modes in here

You can also separate creating a context manager (the __init__ method) and entering the context (the __enter__ method) to increase readability. So instead of writing this code:

with Company(name, id) as company, Person(name, age, gender) as person, Vehicle(brand) as vehicle:
    pass

you can write this code:

company = Company(name, id)
person = Person(name, age, gender)
vehicle = Vehicle(brand)

with company, person, vehicle:
    pass

Note that creating the context manager outside of the with statement makes an impression that the created object can also be further used outside of the statement. If this is not true for your context manager, the false impression may counterpart the readability attempt.

The documentation says:

Most context managers are written in a way that means they can only be used effectively in a with statement once. These single use context managers must be created afresh each time they’re used - attempting to use them a second time will trigger an exception or otherwise not work correctly.

This common limitation means that it is generally advisable to create context managers directly in the header of the with statement where they are used.

You said any suggestions wold be helpful, so currently I resolved my DataTables "cannot read property 'style' of undefined" problem but my problem was basically using wrong indexes at data table initiation phase's columnDefs section. I got 9 columns and the indexes are 0, 1, 2, .. , 8 but I was using indexes for 9 and 10 so after fixing the wrong index issue the fault has disappeared. I hope this helps.

In short, you got to watch your columns amount and indexes if consistent everywhere.

Buggy Code:

    jQuery('#table').DataTable({
        "ajax": {
            url: "something_url",
            type: 'POST'
        },
        "processing": true,
        "serverSide": true,
        "bPaginate": true,
        "sPaginationType": "full_numbers",
        "columns": [
            { "data": "cl1" },
            { "data": "cl2" },
            { "data": "cl3" },
            { "data": "cl4" },
            { "data": "cl5" },
            { "data": "cl6" },
            { "data": "cl7" },
            { "data": "cl8" },
            { "data": "cl9" }
        ],
        columnDefs: [
            { orderable: false, targets: [ 7, 9, 10 ] } //This part was wrong
        ]
    });

Fixed Code:

    jQuery('#table').DataTable({
        "ajax": {
            url: "something_url",
            type: 'POST'
        },
        "processing": true,
        "serverSide": true,

        "sPaginationType": "full_numbers",
        "columns": [
            { "data": "cl1" },
            { "data": "cl2" },
            { "data": "cl3" },
            { "data": "cl4" },
            { "data": "cl5" },
            { "data": "cl6" },
            { "data": "cl7" },
            { "data": "cl8" },

        ],
        columnDefs: [
            { orderable: false, targets: [ 5, 7, 8 ] } //This part is ok now
        ]
    });

sharing what I know of references in JavaScript

In JavaScript, when assigning an object to a variable, the value assigned to the variable is a reference to the object:

var a = {_x000D_
  a: 1,_x000D_
  b: 2,_x000D_
  c: 3_x000D_
};_x000D_
var b = a;_x000D_
_x000D_
// b.c is referencing to a.c value_x000D_
console.log(b.c) // Output: 3_x000D_
// Changing value of b.c_x000D_
b.c = 4_x000D_
// Also changes the value of a.c_x000D_
console.log(a.c) // Output: 4

if you give it 234.545332233 it will give you 234.54

let textData = Double(myTextField.text!)!
let text = String(format: "%.2f", arguments: [textData])
mylabel.text = text

To answer your question directly, when you call console.log("something") from the background, this message is logged, to the background page's console. To view it, you may go to chrome://extensions/ and click on that inspect view under your extension.

When you click the popup, it's loaded into the current page, thus the console.log should show log message in the current page.

I managed this without adding markup, but instead using li:before. This obviously has all the limitations of :before (no old IE support), but it seems to work with IE8, Firefox and Chrome after some very limited testing. The bullet style is also limited by what's in unicode.

li {_x000D_
  list-style: none;_x000D_
}_x000D_
li:before {_x000D_
  /* For a round bullet */_x000D_

The way to keep SELECT dbo.fCalculateEstimateDate(647) call working is:

ALTER function [dbo].[fCalculateEstimateDate] (@vWorkOrderID numeric)
Returns varchar(100)  AS
   Declare @Result varchar(100)
   SELECT @Result = [dbo].[fCalculateEstimateDate_v2] (@vWorkOrderID,DEFAULT)
   Return @Result
Begin
End

CREATE function [dbo].[fCalculateEstimateDate_v2] (@vWorkOrderID numeric,@ToDate DateTime=null)
Returns varchar(100)  AS
Begin
  <Function Body>
End

It looks like someone might have revoked the permissions on sys.configurations for the public role. Or denied access to this view to this particular user. Or the user has been created after the public role was removed from the sys.configurations tables.

Provide SELECT permission to public user sys.configurations object.

Regarding the differences between json and jsonb datatypes, it worth mentioning the official explanation:

PostgreSQL offers two types for storing JSON data: json and jsonb. To implement efficient query mechanisms for these data types, PostgreSQL also provides the jsonpath data type described in Section 8.14.6.

The json and jsonb data types accept almost identical sets of values as input. The major practical difference is one of efficiency. The json data type stores an exact copy of the input text, which processing functions must reparse on each execution; while jsonb data is stored in a decomposed binary format that makes it slightly slower to input due to added conversion overhead, but significantly faster to process, since no reparsing is needed. jsonb also supports indexing, which can be a significant advantage.

Because the json type stores an exact copy of the input text, it will preserve semantically-insignificant white space between tokens, as well as the order of keys within JSON objects. Also, if a JSON object within the value contains the same key more than once, all the key/value pairs are kept. (The processing functions consider the last value as the operative one.) By contrast, jsonb does not preserve white space, does not preserve the order of object keys, and does not keep duplicate object keys. If duplicate keys are specified in the input, only the last value is kept.

In general, most applications should prefer to store JSON data as jsonb, unless there are quite specialized needs, such as legacy assumptions about ordering of object keys.

PostgreSQL allows only one character set encoding per database. It is therefore not possible for the JSON types to conform rigidly to the JSON specification unless the database encoding is UTF8. Attempts to directly include characters that cannot be represented in the database encoding will fail; conversely, characters that can be represented in the database encoding but not in UTF8 will be allowed.

enter image description here The XPath text() function locates elements within a text node while dot (.) locate elements inside or outside a text node. In the image description screenshot, the XPath text() function will only locate Success in DOM Example 2. It will not find success in DOM Example 1 because it's located between the tags.

In addition, the text() function will not find success in DOM Example 3 because success does not have a direct relationship to the element . Here's a video demo explaining the difference between text() and dot (.) https://youtu.be/oi2Q7-0ZIBg

This is not an answer, but too long for a comment.

In reply to JP's answers / comments, I have run the following test to compare the performance of the 2 methods. The Profiler object is a custom class - but in summary, it uses a kernel32 function which is fairly accurate (Private Declare Sub GetLocalTime Lib "kernel32" (lpSystemTime As SYSTEMTIME)).

Sub test()

  Dim origNum As String
  Dim creditOrDebit As String
  Dim b As Boolean
  Dim p As Profiler
  Dim i As Long

  Set p = New_Profiler

  origNum = "30062600006"
  creditOrDebit = "D"

  p.startTimer ("nested_ifs")

  For i = 1 To 1000000

    If creditOrDebit = "D" Then
      If origNum = "006260006" Then
        b = True
      ElseIf origNum = "30062600006" Then
        b = True
      End If
    End If

  Next i

  p.stopTimer ("nested_ifs")
  p.startTimer ("or_and")

  For i = 1 To 1000000

    If (origNum = "006260006" Or origNum = "30062600006") And creditOrDebit = "D" Then
      b = True
    End If

  Next i

  p.stopTimer ("or_and")

  p.printReport

End Sub

The results of 5 runs (in ms for 1m loops):

20-Jun-2012 19:28:25
nested_ifs (x1): 156 - Last Run: 156 - Average Run: 156

Note

If creditOrDebit is not "D", JP's code runs faster (around 60ms vs. 125ms for the or/and code).

select cast(your_float_column as decimal(10,2))
from your_table

decimal(10,2) means you can have a decimal number with a maximal total precision of 10 digits. 2 of them after the decimal point and 8 before.
The biggest possible number would be 99999999.99

Best answer is here: This is case insensitive as well

    var specsFilter = [.....];
    var yourString = "......";

    //if found a match
    if (specsFilter.some((element) => { return new RegExp(element, "ig").test(yourString) })) {
        // do something
    }

I was getting the error with "Add source roots to PYTHONPATH" as well. My problem was that I had two folders with the same name, like project/subproject1/thing/src and project/subproject2/thing/src and I had both of them marked as source root. When I renamed one of the "thing" folders to "thing1" (any unique name), it worked.

Maybe if PyCharm automatically adds selected source roots, it doesn't use the full path and hence mixes up folders with the same name.

If you target a non-rooted device and/or have services in you APK that you don't want to stop as well, the other solutions won't work.

To solve this problem, I've resorted to a broadcast message receiver I've added to my activity in order to stop it.

public class TestActivity extends Activity {
    private static final String STOP_COMMAND = "com.example.TestActivity.STOP";

    private BroadcastReceiver broadcastReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            TestActivity.this.finish();
        }
    };

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

        //other stuff...

        registerReceiver(broadcastReceiver, new IntentFilter(STOP_COMMAND));
    }
}

That way, you can issue this adb command to stop your activity:

adb shell am broadcast -a com.example.TestActivity.STOP

public static void main(String[] args) {

    List<String> ls=new ArrayList<String>();
    ls.add("1");
    ls.add("2");
    ls.add("3");
    ls.add("4");

//Then  you can use "foreache" loop to iterate.

    for(String item:ls){
        System.out.println(item);
    }

}

Your code is correct. Just test to ensure it is being called like:

<script>
function doIt(){
  alert("here i am!");
  __doPostBack('ctl00$ctl00$bLogout','')
}
</script>

<iframe onload="doIt()"></iframe>

Update: The code in this answer is for Super CSV 1.52. Updated code examples for Super CSV 2.4.0 can be found at the project website: http://super-csv.github.io/super-csv/index.html

The SuperCSV project directly supports the parsing and structured manipulation of CSV cells. From http://super-csv.github.io/super-csv/examples_reading.html you'll find e.g.

given a class

public class UserBean {
    String username, password, street, town;
    int zip;

    public String getPassword() { return password; }
    public String getStreet() { return street; }
    public String getTown() { return town; }
    public String getUsername() { return username; }
    public int getZip() { return zip; }
    public void setPassword(String password) { this.password = password; }
    public void setStreet(String street) { this.street = street; }
    public void setTown(String town) { this.town = town; }
    public void setUsername(String username) { this.username = username; }
    public void setZip(int zip) { this.zip = zip; }
}

and that you have a CSV file with a header. Let's assume the following content

username, password,   date,        zip,  town
Klaus,    qwexyKiks,  17/1/2007,   1111, New York
Oufu,     bobilop,    10/10/2007,  4555, New York

You can then create an instance of the UserBean and populate it with values from the second line of the file with the following code

class ReadingObjects {
  public static void main(String[] args) throws Exception{
    ICsvBeanReader inFile = new CsvBeanReader(new FileReader("foo.csv"), CsvPreference.EXCEL_PREFERENCE);
    try {
      final String[] header = inFile.getCSVHeader(true);
      UserBean user;
      while( (user = inFile.read(UserBean.class, header, processors)) != null) {
        System.out.println(user.getZip());
      }
    } finally {
      inFile.close();
    }
  }
}

using the following "manipulation specification"

final CellProcessor[] processors = new CellProcessor[] {
    new Unique(new StrMinMax(5, 20)),
    new StrMinMax(8, 35),
    new ParseDate("dd/MM/yyyy"),
    new Optional(new ParseInt()),
    null
};

Necromancing.
YES YOU CAN, and this is how.
A secret tip for those migrating large junks chunks of code:
The following method is an evil carbuncle of a hack which is actively engaged in carrying out the express work of satan (in the eyes of .NET Core framework developers), but it works:

In public class Startup

add a property

public IConfigurationRoot Configuration { get; }

And then add a singleton IHttpContextAccessor to DI in ConfigureServices.

    // This method gets called by the runtime. Use this method to add services to the container.
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddSingleton<Microsoft.AspNetCore.Http.IHttpContextAccessor, Microsoft.AspNetCore.Http.HttpContextAccessor>();

Then in Configure

    public void Configure(
              IApplicationBuilder app
             ,IHostingEnvironment env
             ,ILoggerFactory loggerFactory
    )
    {

add the DI Parameter IServiceProvider svp, so the method looks like:

    public void Configure(
           IApplicationBuilder app
          ,IHostingEnvironment env
          ,ILoggerFactory loggerFactory
          ,IServiceProvider svp)
    {

Next, create a replacement class for System.Web:

namespace System.Web
{

    namespace Hosting
    {
        public static class HostingEnvironment 
        {
            public static bool m_IsHosted;

            static HostingEnvironment()
            {
                m_IsHosted = false;
            }

            public static bool IsHosted
            {
                get
                {
                    return m_IsHosted;
                }
            }
        }
    }


    public static class HttpContext
    {
        public static IServiceProvider ServiceProvider;

        static HttpContext()
        { }


        public static Microsoft.AspNetCore.Http.HttpContext Current
        {
            get
            {
                // var factory2 = ServiceProvider.GetService<Microsoft.AspNetCore.Http.IHttpContextAccessor>();
                object factory = ServiceProvider.GetService(typeof(Microsoft.AspNetCore.Http.IHttpContextAccessor));

                // Microsoft.AspNetCore.Http.HttpContextAccessor fac =(Microsoft.AspNetCore.Http.HttpContextAccessor)factory;
                Microsoft.AspNetCore.Http.HttpContext context = ((Microsoft.AspNetCore.Http.HttpContextAccessor)factory).HttpContext;
                // context.Response.WriteAsync("Test");

                return context;
            }
        }


    } // End Class HttpContext 


}

Now in Configure, where you added the IServiceProvider svp, save this service provider into the static variable "ServiceProvider" in the just created dummy class System.Web.HttpContext (System.Web.HttpContext.ServiceProvider)

and set HostingEnvironment.IsHosted to true

System.Web.Hosting.HostingEnvironment.m_IsHosted = true;

this is essentially what System.Web did, just that you never saw it (I guess the variable was declared as internal instead of public).

// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory, IServiceProvider svp)
{
    loggerFactory.AddConsole(Configuration.GetSection("Logging"));
    loggerFactory.AddDebug();

    ServiceProvider = svp;
    System.Web.HttpContext.ServiceProvider = svp;
    System.Web.Hosting.HostingEnvironment.m_IsHosted = true;


    app.UseCookieAuthentication(new CookieAuthenticationOptions()
    {
        AuthenticationScheme = "MyCookieMiddlewareInstance",
        LoginPath = new Microsoft.AspNetCore.Http.PathString("/Account/Unauthorized/"),
        AccessDeniedPath = new Microsoft.AspNetCore.Http.PathString("/Account/Forbidden/"),
        AutomaticAuthenticate = true,
        AutomaticChallenge = true,
        CookieSecure = Microsoft.AspNetCore.Http.CookieSecurePolicy.SameAsRequest

       , CookieHttpOnly=false

    });

Like in ASP.NET Web-Forms, you'll get a NullReference when you're trying to access a HttpContext when there is none, such as it used to be in Application_Start in global.asax.

I stress again, this only works if you actually added

services.AddSingleton<Microsoft.AspNetCore.Http.IHttpContextAccessor, Microsoft.AspNetCore.Http.HttpContextAccessor>();

like I wrote you should.
Welcome to the ServiceLocator pattern within the DI pattern ;)
For risks and side effects, ask your resident doctor or pharmacist - or study the sources of .NET Core at github.com/aspnet, and do some testing.

Perhaps a more maintainable method would be adding this helper class

namespace System.Web
{

    public static class HttpContext
    {
        private static Microsoft.AspNetCore.Http.IHttpContextAccessor m_httpContextAccessor;


        public static void Configure(Microsoft.AspNetCore.Http.IHttpContextAccessor httpContextAccessor)
        {
            m_httpContextAccessor = httpContextAccessor;
        }


        public static Microsoft.AspNetCore.Http.HttpContext Current
        {
            get
            {
                return m_httpContextAccessor.HttpContext;
            }
        }


    }


}

And then calling HttpContext.Configure in Startup->Configure

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory, IServiceProvider svp)
{
    loggerFactory.AddConsole(Configuration.GetSection("Logging"));
    loggerFactory.AddDebug();


    System.Web.HttpContext.Configure(app.ApplicationServices.
        GetRequiredService<Microsoft.AspNetCore.Http.IHttpContextAccessor>()
    );

Find the object whose property "Y" has the greatest value in an array of objects

One way would be to use Array reduce..

const max = data.reduce(function(prev, current) {
    return (prev.y > current.y) ? prev : current
}) //returns object

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/Reduce http://caniuse.com/#search=reduce (IE9 and above)

If you don't need to support IE (only Edge), or can use a pre-compiler such as Babel you could use the more terse syntax.

const max = data.reduce((prev, current) => (prev.y > current.y) ? prev : current)

You need to wrap them all in a character class. The current version means replace this sequence of characters with an empty string. When wrapped in square brackets it means replace any of these characters with an empty string.

var cleanString = dirtyString.replace(/[\|&;\$%@"<>\(\)\+,]/g, "");

You could use FindFirstFile which returns a handle and then recursively cal a function which calls FindNextFile.This is a good aproach as the structure referenced would be filled with various data such as alternativeName,lastTmeCreated,modified,attributes etc

But as you use .net framework, you would have to enter the unmanaged area.

Yes, your intuition was good. You shouldn't use three instances of intellij. You can open one Project and add other 'parts' of application as Modules. Add them via project browser, default hotkey is alt+1

We here use simply linear search. At first initialize the index equal to -1 . Then search the array , if found the assign the index value in index variable and break. Otherwise, index = -1.

   int find(int arr[], int n, int key)
   {
     int index = -1;

       for(int i=0; i<n; i++)
       {
          if(arr[i]==key)
          {
            index=i;
            break;
          }
       }
      return index;
    }


 int main()
 {
    int arr[ 5 ] = { 4, 1, 3, 2, 6 };
    int n =  sizeof(arr)/sizeof(arr[0]);
    int x = find(arr ,n, 3);
    cout<<x<<endl;
    return 0;
 }

As noted by S.Lott,

Variable set outside init belong to the class. They're shared by all instances.

Variables created inside init (and all other method functions) and prefaced with self. belong to the object instance.

However, Note that class variables can be accessed via self.<var> until they are masked by an object variable with a similar name This means that reading self.<var> before assigning it a value will return the value of Class.<var> but afterwards it will return obj.<var> . Here is an example

In [20]: class MyClass: 
    ...:     elem = 123 
    ...:  
    ...:     def update(self,i): 
    ...:         self.elem=i  
    ...:     def print(self): 
    ...:         print (MyClass.elem, self.elem) 
    ...:  
    ...: c1 = MyClass()  
    ...: c2 = MyClass() 
    ...: c1.print() 
    ...: c2.print()                                                                                                                                                                                                                                                               
123 123 
123 123 
In [21]: c1.update(1) 
    ...: c2.update(42) 
    ...: c1.print() 
    ...: c2.print()                                                                                                                                                                                                                                                               
123 1 
123 42
In [22]: MyClass.elem=22 
    ...: c1.print()  
    ...: c2.print()

Second note: Consider slots. They may offer a better way to implement object variables.

kind of an old thread, but.. i do this:

$file = 'http://www.google.com';
$file_headers = @get_headers($file);
if ($file_headers) {
    $exists = true;
} else {
    $exists = false;
}

I had a similar issue and using %in% operator instead of the == (equality) operator was the solution:

# %in%

Hope it helps.

Edit: Passing the operator as a reference doesnt work. For simplicity, understand it as a function pointer. You just send the pointer, not a reference. I think you are trying to write something like this.

struct Square
{
    double operator()(double number) { return number * number; }
};

template <class Function>
double integrate(Function f, double a, double b, unsigned int intervals)
{
    double delta = (b - a) / intervals, sum = 0.0;

    while(a < b)
    {
        sum += f(a) * delta;
        a += delta;
    }

    return sum;
}

. .

std::cout << "interval : " << i << tab << tab << "intgeration = "
 << integrate(Square(), 0.0, 1.0, 10) << std::endl;

Consider using System.Collections.Specialized.OrderedDictionary, though it is not generic, or implement your own (example).

OrderedDictionary does not support IndexOf, but it's easy to implement:

public static class OrderedDictionaryExtensions
{
    public static int IndexOf(this OrderedDictionary dictionary, object value)
    {
        for(int i = 0; i < dictionary.Count; ++i)
        {
            if(dictionary[i] == value) return i;
        }
        return -1;
    }
}

I had a specific requirement to do something similar where it would show month-year which can be done by the following:

SELECT DATENAME(month, GETDATE()) + '-' + CAST(YEAR(GETDATE()) AS nvarchar) AS 'Month-Year'

In my particular case, I needed to have it down to the 3 letter month abreviation with a 2 digit year, looking something like this: SELECT LEFT(DATENAME(month, GETDATE()), 3) + '-' + CAST(RIGHT(YEAR(GETDATE()),2) AS nvarchar(2)) AS 'Month-Year'

It seems this is the easiest way to get the latest version of Redis - use NuGet Manager:

1) Open NuGet setup page and download Command-Line Utility (The latest version of the nuget.exe command-line tool is always available from https://nuget.org/nuget.exe)

2) Copy this file to somewhere (for example, C:\Downloads)

3) Start a command prompt as an Administrator and execute follow commands:

cd C:\Downloads
nuget.exe install redis-64

4) In the Downloads folder will be the latest version of Redis (C:\Downloads\Redis-64.2.8.19 in my case)

5) Run redis-server.exe and start working

P.S. Note: redis from Download Redis for windows contains a very old version of Redis: 2.4.6

hi @JackSlayer94 please find the below example to understand how to make an array of size 5.

class Hero {_x000D_
    name: string;_x000D_
    constructor(text: string) {_x000D_
        this.name = text;_x000D_
    }_x000D_
_x000D_
    display() {_x000D_
        return "Hello, " + this.name;_x000D_
    }_x000D_
_x000D_
}_x000D_
_x000D_
let heros:Hero[] = new Array(5);_x000D_
for (let i = 0; i < 5; i++){_x000D_
    heros[i] = new Hero("Name: " + i);_x000D_
}_x000D_
_x000D_
for (let i = 0; i < 5; i++){_x000D_
    console.log(heros[i].display());_x000D_
}

The simplest way to put an image into a button:

<button onclick="myFunction()"><img src="your image name here.png"></button>

This will automatically resize the button to the size of the image.

The accepted answer by @Meherzad only works if the data is in a particular order. It happens to work with the data from the OP question. In my case, I had to modify it to work with my data.

Note This only works when every record's "id" (col1 in the question) has a value GREATER THAN that record's "parent id" (col3 in the question). This is often the case, because normally the parent will need to be created first. However if your application allows changes to the hierarchy, where an item may be re-parented somewhere else, then you cannot rely on this.

This is my query in case it helps someone; note it does not work with the given question because the data does not follow the required structure described above.

select t.col1, t.col2, @pv := t.col3 col3
from (select * from table1 order by col1 desc) t
join (select @pv := 1) tmp
where t.col1 = @pv

The difference is that table1 is being ordered by col1 so that the parent will be after it (since the parent's col1 value is lower than the child's).

If you don't want to depend on @@DATEFIRST or use DATEPART(weekday, DateColumn), just calculate the day of the week yourself.

For Monday based weeks (Europe) simplest is:

SELECT DATEDIFF(day, '17530101', DateColumn) % 7 + 1 AS MondayBasedDay

For Sunday based weeks (America) use:

SELECT DATEDIFF(day, '17530107', DateColumn) % 7 + 1 AS SundayBasedDay

This return the weekday number (1 to 7) ever since January 1st respectively 7th, 1753.

I had the same problem but I use -w 0 option to send only one packet and quit. You should use this command :

echo -n "hello" | nc -4u -w0 localhost 8000

Create a directory db in home, inside db another directory data

cd 
mkdir db
cd db
mkdir data

then type this command--

mongod --dbpath ~/db/data

I found myself in a similar issue. Since I am using maven I needed to update my pom.xml to include something like this:

   ...
</dependencies>
<build>
    <resources>
        <resource>
            <directory>/src/main/resources</directory>
        </resource>
        <resource>
            <directory>../src/main/resources</directory>
        </resource>
    </resources>
    <pluginManagement>
        ...

Note the resource tag in there to specify where that folder is. If you have nested projects (like I do) then you might want to get resources from other areas instead of just in the module you are working in. This helps reduce keeping the same file in each repo if you are using similar config data

Visual Studio 2003 doesn't seem to allow you to set environment variables for debugging.

What I do in C/C++ is use _putenv() in main() and set any variables. Usually I surround it with a #if defined DEBUG_MODE / #endif to make sure only certain builds have it.

_putenv("MYANSWER=42");

I believe you can do the same thing with C# using os.putenv(), i.e.

os.putenv('MYANSWER', '42');

These will set the envrironment variable for that shell process only, and as such is an ephemeral setting, which is what you are looking for.

By the way, its good to use process explorer (http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx), which is a sysinternals tool. You can see what a given process' copy of the environment variables is, so you can validate that what you set is what you got.

Download the developer edition. There you can choose Express as license when installing.

I have not seen bool option in other answers so I hope below code will help someone.

Just use Any()

string myString = "test";
bool exists = myList
             .Where(w => w.COLUMN_TO_CHECK.Contains(myString)).Any();

Sometimes you still need to know if Cookie exists in Response. Then you can check if cookie key exists:

HttpContext.Current.Response.Cookies.AllKeys.Contains("myCookie")

More info can be found here.

In my case I had to modify Response Cookie in Application_EndRequest method in Global.asax. If Cookie doesn't exist I don't touch it:

string name = "myCookie";
HttpContext context = ((HttpApplication)sender).Context;
HttpCookie cookie = null;

if (context.Response.Cookies.AllKeys.Contains(name))
{
    cookie = context.Response.Cookies[name];
}

if (cookie != null)
{
    // update response cookie
}

I think you are looking for the Jquery Load function. You would just use that function with an onclick function tied to the a tag or a button if you like.

Follow these steps:-

1. Add dependencies of flutter_luncher_icons in pubspec.yaml file.You can find this plugin from here.

2. Add your required images in asstes folder and pubspec.yaml file as below .

pubspec.yaml

What about something like this, without a button:

<input type="text" placeholder="Search..." [value]="searchValue" onblur="this.value=''">

Lower mm means minutes, so

DateTime.Now.ToString("dd/MM/yyyy");  

or

DateTime.Now.ToString("d");  

or

DateTime.Now.ToShortDateString()

works.

Standard Date and Time Format Strings

Try this solution. Only fires once the page loads and then during window resize at predefined resizeDelay.

$(document).ready(function()
{   
   var resizeDelay = 200;
   var doResize = true;
   var resizer = function () {
      if (doResize) {

        //your code that needs to be executed goes here

        doResize = false;
      }
    };
    var resizerInterval = setInterval(resizer, resizeDelay);
    resizer();

    $(window).resize(function() {
      doResize = true;

If you don't want to or can't use Android Studio, you can use the create-android-keystore NPM tool:

$ create-android-keystore quick

Which results in a newly generated keystore in the current directory.

More info: https://www.npmjs.com/package/create-android-keystore

The String class exposes some methods to enable this, such as IndexOf and LastIndexOf, so that you may do this:

Dim myText = "abcde"
Dim dIndex = myText.IndexOf("d")
If (dIndex > -1) Then

End If

I'd like to expand on Obertklep's answer. In his example it is an NPM module called body-parser which is doing most of the work. Where he puts req.body.name, I believe he/she is using body-parser to get the contents of the name attribute(s) received when the form is submitted.

If you do not want to use Express, use querystring which is a built-in Node module. See the answers in the link below for an example of how to use querystring.

It might help to look at this answer, which is very similar to your quest.

Type       | Approx. Length     | Exact Max. Length Allowed
-----------------------------------------------------------
TINYTEXT   | 256 Bytes          |           255 characters
TEXT       |  64 Kilobytes      |        65,535 characters
MEDIUMTEXT |  16 Megabytes      |    16,777,215 characters
LONGTEXT   |   4 Gigabytes      | 4,294,967,295 characters

Basically, it's like:

"Exact Max. Length Allowed" = "Approx. Length" in bytes - 1

Note: If using multibyte characters (like Arabic, where each Arabic character takes 2 bytes), the column "Exact Max. Length Allowed" for TINYTEXT can hold be up to 127 Arabic characters (Note: space, dash, underscore, and other such characters, are 1-byte characters).

Since str_split() function is not multibyte safe, an easy solution to split UTF-8 encoded string is to use preg_split() with u (PCRE_UTF8) modifier.

preg_split( '//u', $str, null, PREG_SPLIT_NO_EMPTY )

I would add an useful side note and a general suggestion to minimize JPG and PNG.

First of all, ImageMagick reads (or better "guess"...) the input jpeg compression level and so if you don't add -quality NN at all, the output should use the same level as input. Sometimes could be an important feature. Otherwise the default level is -quality 92 (see www.imagemagick.org)

The suggestion is about a really awesome free tool ImageOptim, also for batch process.
You can get smaller jpgs (and pngs as well, especially after the use of the free ImageAlpha [not batch process] or the free Pngyu if you need batch process).
Not only, these tools are for Mac and Win and as Command Line (I suggest installing using Brew and then searching in Brew formulas).

SIMPLIEST WAY TO HANDLE TIMEOUT LOOP

function myFunc (terminator = false) {
    if(terminator) {
        clearTimeout(timeOutVar);
    } else {
        // do something
        timeOutVar = setTimeout(function(){myFunc();}, 1000);
    }
}   
myFunc(true); //  -> start loop
myFunc(false); //  -> end loop

From the horse's mouth:

Foreign keys allow key values that are all NULL, even if there are no matching PRIMARY or UNIQUE keys

No Constraints on the Foreign Key

When no other constraints are defined on the foreign key, any number of rows in the child table can reference the same parent key value. This model allows nulls in the foreign key. ...

NOT NULL Constraint on the Foreign Key

When nulls are not allowed in a foreign key, each row in the child table must explicitly reference a value in the parent key because nulls are not allowed in the foreign key.

Any number of rows in the child table can reference the same parent key value, so this model establishes a one-to-many relationship between the parent and foreign keys. However, each row in the child table must have a reference to a parent key value; the absence of a value (a null) in the foreign key is not allowed. The same example in the previous section can be used to illustrate such a relationship. However, in this case, employees must have a reference to a specific department.

UNIQUE Constraint on the Foreign Key

When a UNIQUE constraint is defined on the foreign key, only one row in the child table can reference a given parent key value. This model allows nulls in the foreign key.

This model establishes a one-to-one relationship between the parent and foreign keys that allows undetermined values (nulls) in the foreign key. For example, assume that the employee table had a column named MEMBERNO, referring to an employee membership number in the company insurance plan. Also, a table named INSURANCE has a primary key named MEMBERNO, and other columns of the table keep respective information relating to an employee insurance policy. The MEMBERNO in the employee table must be both a foreign key and a unique key:

• To enforce referential integrity rules between the EMP_TAB and INSURANCE tables (the FOREIGN KEY constraint)

• To guarantee that each employee has a unique membership number (the UNIQUE key constraint)

UNIQUE and NOT NULL Constraints on the Foreign Key

When both UNIQUE and NOT NULL constraints are defined on the foreign key, only one row in the child table can reference a given parent key value, and because NULL values are not allowed in the foreign key, each row in the child table must explicitly reference a value in the parent key.

One possible situation where this might be needed:

If you are using finally block to close connections but in the try block, the program exits with sys.exit() before the connection is defined. In this case, the finally block will be called and the connection closing statement will fail since no connection was created.

I think this simply just work with bootstrap 4, i adding in inline but you always can bind event from script.

  <a 
onmouseover="$('#navbarDropdownMenuLink').dropdown('toggle')"
class="nav-link dropdown-toggle" 
href="http://example.com" 
id="navbarDropdownMenuLink" 
data-toggle="dropdown" 
aria-haspopup="true" 
aria-expanded="false">
      Dropdown link
    </a>

This will capture requests for files like version, release, and README.md, etc. which should be treated either as endpoints, if defined (as in the case of /release), or as "not found."

The 1s are because everything is perfectly correlated with itself, and the NAs are because there are NAs in your variables.

You will have to specify how you want R to compute the correlation when there are missing values, because the default is to only compute a coefficient with complete information.

You can change this behavior with the use argument to cor, see ?cor for details.

Solution for case when two lists have the same elements, but different order:

public boolean isDifferentLists(List<Integer> listOne, List<Integer> listTwo) {
    if(isNullLists(listOne, listTwo)) {
        return false;
    }

    if (hasDifferentSize(listOne, listTwo)) {
        return true;
    }

    List<Integer> listOneCopy = Lists.newArrayList(listOne);
    List<Integer> listTwoCopy = Lists.newArrayList(listTwo);
    listOneCopy.removeAll(listTwoCopy);

    return CollectionUtils.isNotEmpty(listOneCopy);
}

private boolean isNullLists(List<Integer> listOne, List<Integer> listTwo) {
    return listOne == null && listTwo == null;
}

private boolean hasDifferentSize(List<Integer> listOne, List<Integer> listTwo) {
    return (listOne == null && listTwo != null) || (listOne != null && listTwo == null) || (listOne.size() != listTwo.size());
}

The executable used to run batch scripts is cmd.exe which uses the /c flag to specify the name of the batch file to run:

Runtime.getRuntime().exec(new String[]{"cmd.exe", "/c", "build.bat"});

Theoretically you should also be able to run Scons in this manner, though I haven't tested this:

Runtime.getRuntime().exec(new String[]{"scons", "-Q", "implicit-deps-changed", "build\file_load_type", "export\file_load_type"});

EDIT: Amara, you say that this isn't working. The error you listed is the error you'd get when running Java from a Cygwin terminal on a Windows box; is this what you're doing? The problem with that is that Windows and Cygwin have different paths, so the Windows version of Java won't find the scons executable on your Cygwin path. I can explain further if this turns out to be your problem.

Normally I would recommend floating but from your 3 requirements I would suggest this:

position: absolute;
right: 10px;
top: 5px;

Don't forget position: relative; on the parent div

DEMO

I know this was asked quite a while ago, after trying out some of the above steps. What helped me were the following steps and this article.

I located the reference and changed the PublicKeyToken from the one being referenced to the older one.

I hope this helps too.

Label vs. Location

The main distinction between the two methods is:

• loc gets rows (and/or columns) with particular labels.

• iloc gets rows (and/or columns) at integer locations.

To demonstrate, consider a series s of characters with a non-monotonic integer index:

>>> s = pd.Series(list("abcdef"), index=[49, 48, 47, 0, 1, 2]) 
49    a
48    b
47    c
0     d
1     e
2     f

>>> s.loc[0]    # value at index label 0
'd'

>>> s.iloc[0]   # value at index location 0
'a'

>>> s.loc[0:1]  # rows at index labels between 0 and 1 (inclusive)
0    d
1    e

>>> s.iloc[0:1] # rows at index location between 0 and 1 (exclusive)
49    a

Here are some of the differences/similarities between s.loc and s.iloc when passed various objects:

loc's label-querying capabilities extend well-beyond integer indexes and it's worth highlighting a couple of additional examples.

Here's a Series where the index contains string objects:

>>> s2 = pd.Series(s.index, index=s.values)
>>> s2
a    49
b    48
c    47
d     0
e     1
f     2

Since loc is label-based, it can fetch the first value in the Series using s2.loc['a']. It can also slice with non-integer objects:

>>> s2.loc['c':'e']  # all rows lying between 'c' and 'e' (inclusive)
c    47
d     0
e     1

For DateTime indexes, we don't need to pass the exact date/time to fetch by label. For example:

>>> s3 = pd.Series(list('abcde'), pd.date_range('now', periods=5, freq='M')) 
>>> s3
2021-01-31 16:41:31.879768    a
2021-02-28 16:41:31.879768    b
2021-03-31 16:41:31.879768    c
2021-04-30 16:41:31.879768    d
2021-05-31 16:41:31.879768    e

Then to fetch the row(s) for March/April 2021 we only need:

>>> s3.loc['2021-03':'2021-04']
2021-03-31 17:04:30.742316    c
2021-04-30 17:04:30.742316    d

Rows and Columns

loc and iloc work the same way with DataFrames as they do with Series. It's useful to note that both methods can address columns and rows together.

When given a tuple, the first element is used to index the rows and, if it exists, the second element is used to index the columns.

Consider the DataFrame defined below:

>>> import numpy as np 
>>> df = pd.DataFrame(np.arange(25).reshape(5, 5),  
                      index=list('abcde'), 
                      columns=['x','y','z', 8, 9])
>>> df
    x   y   z   8   9
a   0   1   2   3   4
b   5   6   7   8   9
c  10  11  12  13  14
d  15  16  17  18  19
e  20  21  22  23  24

Then for example:

>>> df.loc['c': , :'z']  # rows 'c' and onwards AND columns up to 'z'
    x   y   z
c  10  11  12
d  15  16  17
e  20  21  22

>>> df.iloc[:, 3]        # all rows, but only the column at index location 3
a     3
b     8
c    13
d    18
e    23

Sometimes we want to mix label and positional indexing methods for the rows and columns, somehow combining the capabilities of loc and iloc.

For example, consider the following DataFrame. How best to slice the rows up to and including 'c' and take the first four columns?

>>> import numpy as np 
>>> df = pd.DataFrame(np.arange(25).reshape(5, 5),  
                      index=list('abcde'), 
                      columns=['x','y','z', 8, 9])
>>> df
    x   y   z   8   9
a   0   1   2   3   4
b   5   6   7   8   9
c  10  11  12  13  14
d  15  16  17  18  19
e  20  21  22  23  24

We can achieve this result using iloc and the help of another method:

>>> df.iloc[:df.index.get_loc('c') + 1, :4]
    x   y   z   8
a   0   1   2   3
b   5   6   7   8
c  10  11  12  13

get_loc() is an index method meaning "get the position of the label in this index". Note that since slicing with iloc is exclusive of its endpoint, we must add 1 to this value if we want row 'c' as well.

Honestly, I am going to argue that using NewRelic for profiling is the best.

It's a PHP extension which doesn't seem to slow down runtime at all and they do the monitoring for you, allowing decent drill down. In the expensive version they allow heavy drill down (but we can't afford their pricing model).

Still, even with the free/standard plan, it's obvious and simple where most of the low hanging fruit is. I also like that it can give you an idea on DB interactions too.

In case you are using zsh you can use for example the -E or -i switch:

history -E

If you do a man zshoptions or man zshbuiltins you can find out more information about these switches as well as other info related to history:

Also when listing,
 -d     prints timestamps for each event
 -f     prints full time-date stamps in the US `MM/DD/YY hh:mm' format
 -E     prints full time-date stamps in the European `dd.mm.yyyy hh:mm' format
 -i     prints full time-date stamps in ISO8601 `yyyy-mm-dd hh:mm' format
 -t fmt prints time and date stamps in the given format; fmt is formatted with the strftime function with the zsh extensions  described  for  the  %D{string} prompt format in the section EXPANSION OF PROMPT SEQUENCES in zshmisc(1).  The resulting formatted string must be no more than 256 characters or will not be printed
 -D     prints elapsed times; may be combined with one of the options above

If you want to manually count it, the size of a struct is just the size of each of its data members after accounting for alignment. There's no magic overhead bytes for a struct.

For basic HTML, you can just add an img tag with the src set to your image URL inside the HREF (A)

<a href="http://www.google.com"><img src="http://problemio.com/img/ui/add_problem.png" /></a>

tl;dr: baz() { this.foo(); this.bar() }

In ES2015 this construct:

var obj = {
    foo() { console.log('foo') }
}

is equal to this ES5 code:

var obj = {
    foo : function foo() { console.log('foo') }
}

exports.default = {} is like creating an object, your default export translates to ES5 code like this:

exports['default'] = {
    foo: function foo() {
        console.log('foo');
    },
    bar: function bar() {
        console.log('bar');
    },
    baz: function baz() {
        foo();bar();
    }
};

now it's kind of obvious (I hope) that baz tries to call foo and bar defined somewhere in the outer scope, which are undefined. But this.foo and this.bar will resolve to the keys defined in exports['default'] object. So the default export referencing its own methods shold look like this:

export default {
    foo() { console.log('foo') }, 
    bar() { console.log('bar') },
    baz() { this.foo(); this.bar() }
}

As the docs say, this can be achieved just by using set instead if push.

As the docs say, it is not recommended (due to possible overwrite by other user at the "same" time).

But in some cases it's helpful to have control over the feed's content including keys.

As an example of webapp in js, 193 being your id generated elsewhere, simply:

 firebase.initializeApp(firebaseConfig);
  var data={
      "name":"Prague"
  };
  firebase.database().ref().child('areas').child("193").set(data);

This will overwrite any area labeled 193 or create one if it's not existing yet.

Don't use Math.random in anycase since it generated a non-cryptographic source of random numbers

Solution below using crypto.getRandomValues

function uuidv4() {
  return "xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx".replace(/[xy]/g, (c) => {
    // tslint:disable-next-line: no-bitwise
    const r =
      (window.crypto.getRandomValues(new Uint32Array(1))[0] *
        Math.pow(2, -32) * 16) |
      0;
    // tslint:disable-next-line: no-bitwise
    const v = c === "x" ? r : (r & 0x3) | 0x8;
    return v.toString(16);
  });
}

For JUnit 4 users, System Lambda as suggested by Stefan Birkner is a great fit.

In case you are using JUnit 5, there is the JUnit Pioneer extension pack. It comes with @ClearEnvironmentVariable and @SetEnvironmentVariable. From the docs:

The @ClearEnvironmentVariable and @SetEnvironmentVariable annotations can be used to clear, respectively, set the values of environment variables for a test execution. Both annotations work on the test method and class level, are repeatable as well as combinable. After the annotated method has been executed, the variables mentioned in the annotation will be restored to their original value or will be cleared if they didn't have one before. Other environment variables that are changed during the test, are not restored.

Example:

@Test
@ClearEnvironmentVariable(key = "SOME_VARIABLE")
@SetEnvironmentVariable(key = "ANOTHER_VARIABLE", value = "new value")
void test() {
    assertNull(System.getenv("SOME_VARIABLE"));
    assertEquals("new value", System.getenv("ANOTHER_VARIABLE"));
}

I was having alot of trouble with this because I was using:

if($.cookie('token') === null || $.cookie('token') === "")
{
      //no cookie
}
else
{
     //have cookie
}

The above was ALWAYS returning false, no matter what I did in terms of setting the cookie or not. From my tests it seems that the object is therefore undefined before it's set so adding the following to my code fixed it.

if($.cookie('token') === null || $.cookie('token') === "" 
    || $.(cookie('token') === "null" || $.cookie('token') === undefined)
{
      //no cookie
}
else
{
     //have cookie
}

del parentpath (or just place the .bat file inside parent folder) *.txt /s

That will delete all .txt files in the parent and all sub folders. If you want to delete multiple file extensions just add a space and do the same thing. Ex. *.txt *.dll *.xml

Try using TabulaPDF (https://github.com/tabulapdf/tabula) . This is very good library to extract table content from the PDF file. It is very as expected.

Good luck. :)

You need slightly different error handling for powershell functions and for calling exe's, and you need to be sure to tell the caller of your script that it has failed. Building on top of Exec from the library Psake, a script that has the structure below will stop on all errors, and is usable as a base template for most scripts.

Set-StrictMode -Version latest
$ErrorActionPreference = "Stop"


# Taken from psake https://github.com/psake/psake
<#
.SYNOPSIS
  This is a helper function that runs a scriptblock and checks the PS variable $lastexitcode
  to see if an error occcured. If an error is detected then an exception is thrown.
  This function allows you to run command-line programs without having to
  explicitly check the $lastexitcode variable.
.EXAMPLE
  exec { svn info $repository_trunk } "Error executing SVN. Please verify SVN command-line client is installed"
#>
function Exec
{
    [CmdletBinding()]
    param(
        [Parameter(Position=0,Mandatory=1)][scriptblock]$cmd,
        [Parameter(Position=1,Mandatory=0)][string]$errorMessage = ("Error executing command {0}" -f $cmd)
    )
    & $cmd
    if ($lastexitcode -ne 0) {
        throw ("Exec: " + $errorMessage)
    }
}

Try {

    # Put all your stuff inside here!

    # powershell functions called as normal and try..catch reports errors 
    New-Object System.Net.WebClient

}

Got this error on linux because of weird file permissions in tomcat distro. Some files an directories are not readable for other users. I use separate CATALINA_HOME and CATALINA_BASE, so my tomcat is owned by root and is runned by restricted user.

Fixing it like that:

( cd /usr/local/share/tomcat9/ && for file in `find ./ -type d ! -perm -o=r`; do echo "$file"; chmod o+rx "$file"; done && for file in `find ./ ! -perm -o=r`; do echo "$file"; chmod o+r "$file"; done )

You're talking about template literals.

They allow for both multiline strings and string interpolation.

Multiline strings:

console.log(`foo_x000D_
bar`);_x000D_
// foo_x000D_
// bar

String interpolation:

var foo = 'bar';_x000D_
console.log(`Let's meet at the ${foo}`);_x000D_
// Let's meet at the bar

The issue has been resolved while installation of the maven settings is provided as External in Eclipse. The navigation settings are Window --> Preferences --> Installations. Select the External as installation Type, provide the Installation home and name and click on Finish. Finally select this as default installations.

List<KeyValuePair<string, string>> kvpList = new List<KeyValuePair<string, string>>()
{
    new KeyValuePair<string, string>("Key1", "Value1"),
    new KeyValuePair<string, string>("Key2", "Value2"),
    new KeyValuePair<string, string>("Key3", "Value3"),
};

kvpList.Insert(0, new KeyValuePair<string, string>("New Key 1", "New Value 1"));

Using this code:

foreach (KeyValuePair<string, string> kvp in kvpList)
{
    Console.WriteLine(string.Format("Key: {0} Value: {1}", kvp.Key, kvp.Value);
}

the expected output should be:

Key: New Key 1 Value: New Value 1
Key: Key 1 Value: Value 1
Key: Key 2 Value: Value 2
Key: Key 3 Value: Value 3

The same will work with a KeyValuePair or whatever other type you want to use..

Edit -

To lookup by the key, you can do the following:

var result = stringList.Where(s => s == "Lookup");

You could do this with a KeyValuePair by doing the following:

var result = kvpList.Where (kvp => kvp.Value == "Lookup");

Last edit -

Made the answer specific to KeyValuePair rather than string.

In my case, I have solved this way:

$scope.MyObject = // get from database or other sources;
$scope.MyObject.Date = new Date($scope.MyObject.Date);

and input type date is ok

A useful code when you have the array in your query:

var queryString = Object.keys(query).map(key => {
    if (query[key].constructor === Array) {
        var theArrSerialized = ''
        for (let singleArrIndex of query[key]) {
            theArrSerialized = theArrSerialized + key + '[]=' + singleArrIndex + '&'
        }
        return theArrSerialized
    }
    else {
        return key + '=' + query[key] + '&'
    }
}
).join('');
console.log('?' + queryString)

The short answer is:

$milliseconds = round(microtime(true) * 1000);

Android Studio Users:

If you want to use grade, go to http://search.maven.org/ and search for your maven repo. Then, click on the "latest version" and in the details page on the bottom left you will see "Gradle" where you can then copy/paste that link into your app's build.gradle.

This should do the trick! :)

B1 =ROW(A5)

To send json to the server, you first have to create json

function sendData() {
    $.ajax({
        url: '/helloworld',
        type: 'POST',
        contentType: 'application/json',
        data: JSON.stringify({
            name:"Bob",
            ...
        }),
        dataType: 'json'
    });
}

This is how you would structure the ajax request to send the json as a post var.

function sendData() {
    $.ajax({
        url: '/helloworld',
        type: 'POST',
        data: { json: JSON.stringify({
            name:"Bob",
            ...
        })},
        dataType: 'json'
    });
}

The json will now be in the json post var.

In addition to @KenM's answer, another important distinction is that, when loading in a saved object, you can assign the contents of an Rds file. Not so for Rda

> x <- 1:5
> save(x, file="x.Rda")
> saveRDS(x, file="x.Rds")
> rm(x)

## ASSIGN USING readRDS
> new_x1 <- readRDS("x.Rds")
> new_x1
[1] 1 2 3 4 5

## 'ASSIGN' USING load -- note the result
> new_x2 <- load("x.Rda")
loading in to  <environment: R_GlobalEnv> 
> new_x2
[1] "x"
# NOTE: `load()` simply returns the name of the objects loaded. Not the values. 
> x
[1] 1 2 3 4 5

The Unicode character U+FEFF is the byte order mark, or BOM, and is used to tell the difference between big- and little-endian UTF-16 encoding. If you decode the web page using the right codec, Python will remove it for you. Examples:

#!python2
#coding: utf8
u = u'ABC'
e8 = u.encode('utf-8')        # encode without BOM
e8s = u.encode('utf-8-sig')   # encode with BOM
e16 = u.encode('utf-16')      # encode with BOM
e16le = u.encode('utf-16le')  # encode without BOM
e16be = u.encode('utf-16be')  # encode without BOM
print 'utf-8     %r' % e8
print 'utf-8-sig %r' % e8s
print 'utf-16    %r' % e16
print 'utf-16le  %r' % e16le
print 'utf-16be  %r' % e16be
print
print 'utf-8  w/ BOM decoded with utf-8     %r' % e8s.decode('utf-8')
print 'utf-8  w/ BOM decoded with utf-8-sig %r' % e8s.decode('utf-8-sig')
print 'utf-16 w/ BOM decoded with utf-16    %r' % e16.decode('utf-16')
print 'utf-16 w/ BOM decoded with utf-16le  %r' % e16.decode('utf-16le')

Note that EF BB BF is a UTF-8-encoded BOM. It is not required for UTF-8, but serves only as a signature (usually on Windows).

Output:

utf-8     'ABC'
utf-8-sig '\xef\xbb\xbfABC'
utf-16    '\xff\xfeA\x00B\x00C\x00'    # Adds BOM and encodes using native processor endian-ness.
utf-16le  'A\x00B\x00C\x00'
utf-16be  '\x00A\x00B\x00C'

utf-8  w/ BOM decoded with utf-8     u'\ufeffABC'    # doesn't remove BOM if present.
utf-8  w/ BOM decoded with utf-8-sig u'ABC'          # removes BOM if present.
utf-16 w/ BOM decoded with utf-16    u'ABC'          # *requires* BOM to be present.
utf-16 w/ BOM decoded with utf-16le  u'\ufeffABC'    # doesn't remove BOM if present.

Note that the utf-16 codec requires BOM to be present, or Python won't know if the data is big- or little-endian.

This can also be done through the SSMS GUI.

1. Put your table in design view (Right click on table in object explorer->Design)
2. Add a column to the table (or click on the column you want to update if it already exists)
3. In Column Properties, enter (getdate()) in Default Value or Binding field as pictured below

You could use the CSS3 background-size property for this.

.header .logo {
background-size: 100%;
}

Somehow, where you are using Sentry, you're not using its Facade, but the class itself. When you call a class through a Facade you're not really using statics, it's just looks like you are.

Do you have this:

use Cartalyst\Sentry\Sentry; 

In your code?

Ok, but if this line is working for you:

$user = $this->sentry->register(array(     'username' => e($data['username']),     'email' => e($data['email']),      'password' => e($data['password'])     )); 

So you already have it instantiated and you can surely do:

$adminGroup = $this->sentry->findGroupById(5); 

There actually is a way to deploy to a device running a newer iOS that the particular version of Xcode might not actually support. What you need to do is copy over the folder that contains the Developer Disk Image from the newer version of Xcode.

For example, you can deploy to a device running iOS 9.3 using Xcode 7.2.1 (which only supports up to iOS 9.2) using this method. Go to the Xcode 7.3 install and navigate to:

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport

From here, copy over the folder that contains the version you are trying to run on the older version of Xcode (for this example, it's 9.3 with the build number in parenthesis). Copy this folder over to the other install of Xcode, and now you should be able to deploy to a device running that particular version of iOS.

This will fail, however, if you're utilizing API calls that were specifically added to the newer version of the SDK. In that case, you will be forced to update Xcode.

Use margins instead of line-height and then apply float to the buttons. By default they are displaying as inline-block, so when one is pushed down the hole line is pushed down with him. Float fixes this:

#header button {
    float:left;
}

Here's a working jsfidle.

I can highly recommend checking out the Visual Studio plugin ReSharper. It has a QuickFix feature that does the same (and a lot more).

But ReSharper doesn't require the cursor to be located on the actual code that requires a new namespace. Say, you copy/paste some code into the source file, and just a few clicks of Alt + Enter, and all the required usings are included.

Oh, and it also makes sure that the required assembly reference is added to your project. Say for example, you create a new project containing NUnit unit tests. The first class you write, you add the [TestFixture] attribute. If you already have one project in your solution that references the NUnit DLL file, then ReSharper is able to see that the TestFixtureAttribute comes from that DLL file, so it will automatically add that assembly reference to your new project.

And it also adds required namespaces for extension methods. At least the ReSharper version 5 beta does. I'm pretty sure that Visual Studio's built-in resolve function doesn't do that.

On the down side, it's a commercial product, so you have to pay for it. But if you work with software commercially, the gained productivity (the plug in does a lot of other cool stuff) outweighs the price tag.

Yes, I'm a fan ;)

Use open(file, mode) for files. The mode is a variant of 'r' for read, 'w' for write, and possibly 'b' appended (e.g., 'rb') to open binary files. See the link below.

Use open with readline() or readlines(). The former will return a line at a time, while the latter returns a list of the lines.

Use split(delimiter) to split on the comma.

Lastly, you need to cast each item to an integer: int(foo). You'll probably want to surround your cast with a try block followed by except ValueError as in the link below.

You can also use 'multiple assignment' to assign a and b at once:

>>>a, b = map(int, "2342342,2234234".split(","))  
>>>print a  
2342342
>>>type(a)  
<type 'int'>

$("#ActionBox").css("marginTop", foo);

The simplest and easiest way is to execute your particular script with -NoExit param.

1.Open run box by pressing:

Win + R

2.Then type into input prompt:

PowerShell -NoExit "C:\folder\script.ps1"

and execute.

In Visual Studio 2008, CTRL+E+W.

Route your path, and take the params, and return:

All the methods and variables in Color are static. You can not instantiate a Color object.

Official Color Docs

The Color class defines methods for creating and converting color ints.

Colors are represented as packed ints, made up of 4 bytes: alpha, red, green, blue.

The values are unpremultiplied, meaning any transparency is stored solely in the alpha component, and not in the color components.

The components are stored as follows (alpha << 24) | (red << 16) | (green << 8) | blue.

Each component ranges between 0..255 with 0 meaning no contribution for that component, and 255 meaning 100% contribution.

Thus opaque-black would be 0xFF000000 (100% opaque but no contributions from red, green, or blue), and opaque-white would be 0xFFFFFFFF

It is simple. The first thing that you have to understand the design of the Python interpreter. It doesn't allocate memory for all the variables basically if any two or more variable has the same value it just map to that value.

let's go to the code example,

In [6]: a = 10

In [7]: id(a)
Out[7]: 10914656

In [8]: b = 10

In [9]: id(b)
Out[9]: 10914656

In [10]: c = 11

In [11]: id(c)
Out[11]: 10914688

In [12]: d = 21

In [13]: id(d)
Out[13]: 10915008

In [14]: e = 11

In [15]: id(e)
Out[15]: 10914688

In [16]: e = 21

In [17]: id(e)
Out[17]: 10915008

In [18]: e is d
Out[18]: True
In [19]: e = 30

In [20]: id(e)
Out[20]: 10915296

From the above output, variables a and b shares the same memory, c and d has different memory when I create a new variable e and store a value (11) which is already present in the variable c so it mapped to that memory location and doesn't create a new memory when I change the value present in the variable e to 21 which is already present in the variable d so now variables d and e share the same memory location. At last, I change the value in the variable e to 30 which is not stored in any other variable so it creates a new memory for e.

so any variable which is having same value shares the memory.

Not for list and dictionary objects

let's come to your question.

when multiple keys have same value then all shares same memory so the thing that you expect is already there in python.

you can simply use it like this

In [49]: dictionary = {
    ...:     'k1':1,
    ...:     'k2':1,
    ...:     'k3':2,
    ...:     'k4':2}
    ...:     
    ...:     

In [50]: id(dictionary['k1'])
Out[50]: 10914368

In [51]: id(dictionary['k2'])
Out[51]: 10914368

In [52]: id(dictionary['k3'])
Out[52]: 10914400

In [53]: id(dictionary['k4'])
Out[53]: 10914400

From the above output, the key k1 and k2 mapped to the same address which means value one stored only once in the memory which is multiple key single value dictionary this is the thing you want. :P

The right is php_memcache.dll. In my case i was using lib compiled with vc9 instead of vc6 compiler. In apatche error logs i got something like:

PHP Startup: sqlanywhere: Unable to initialize module Module compiled with build ID=API20090626, TS,VC9 PHP compiled with build ID=API20090626, TS,VC6 These options need to match

Check if you have same log and try downloading different dll that are compiled with different compiler.

If you have a another server with a good version of the same table you can make a copy(table_copy), transfer the table_copy to the problem server. Then delete the problem table and rename table_copy to table.

So is there any other method to achieve this goal?

No. In order to convert an image to a byte array you have to specify an image format - just as you have to specify an encoding when you convert text to a byte array.

If you're worried about compression artefacts, pick a lossless format. If you're worried about CPU resources, pick a format which doesn't bother compressing - just raw ARGB pixels, for example. But of course that will lead to a larger byte array.

Note that if you pick a format which does include compression, there's no point in then compressing the byte array afterwards - it's almost certain to have no beneficial effect.

if you get this error "Value does not fall within the expected range" in this line:

SPFolder myLibrary = oWeb.Folders[documentLibraryName];

use instead this to fix the error:

SPFolder myLibrary = oWeb.GetList(URL OR NAME).RootFolder;

Use always URl to get Lists or others because they are unique, names are not the best way ;)

Store method:

public function upload($img){
   $filename = Carbon::now() . '-' .  $img->getClientOriginalName();
   return Storage::put($filename, File::get($img)) ? $filename : '';
}

Route:

 Route::get('image/{filename}', [
        'as'   => 'product.image',
        'uses' => 'ProductController@getImage',
    ]);

Controller:

 public function getImage($filename)
    {
        $file = Storage::get($filename);

        return new Response($file, 200);
    }

View:

 <img src="{{ route('product.image', ['filename' => $yourImageName]) }}" alt="your image"/>

You can always do

('0' + deg).slice(-2)

See slice():

You can also use negative numbers to select from the end of an array

Hence

('0' + 11).slice(-2) // '11'
('0' + 4).slice(-2)  // '04'

For ease of access, you could of course extract it to a function, or even extend Number with it:

Number.prototype.pad = function(n) {
    return new Array(n).join('0').slice((n || 2) * -1) + this;
}

Which will allow you to write:

c += deg.pad() + '° '; // "04° "

The above function pad accepts an argument specifying the length of the desired string. If no such argument is used, it defaults to 2. You could write:

deg.pad(4) // "0045"

Note the obvious drawback that the value of n cannot be higher than 11, as the string of 0's is currently just 10 characters long. This could of course be given a technical solution, but I did not want to introduce complexity in such a simple function. (Should you elect to, see alex's answer for an excellent approach to that).

Note also that you would not be able to write 2.pad(). It only works with variables. But then, if it's not a variable, you'll always know beforehand how many digits the number consists of.

You may want to use the Continue statement to continue with the innermost loop.

Excerpt from PowerShell help file:

In a script, the continue statement causes program flow to move immediately to the top of the innermost loop controlled by any of these statements:

• for
• foreach
• while

Please use the following sql query; this worked for my case.

select * FROM   INFORMATION_SCHEMA.Columns where table_name = 'tablename';

On local server your following query will work

DELIMITER |

CREATE PROCEDURE sample_sp_with_params (IN empId INT UNSIGNED, OUT oldName VARCHAR(20), INOUT newName VARCHAR(20))

BEGIN

SELECT `first name` into oldName FROM emp where id = empId;

UPDATE emp SET `first name`= newName where id = empId;

END

|

DELIMITER ;

but on production server it might not work. depend on mysql version you are using. I had a same problem on powweb server, i removed delimiter and begin keywords, it works fine. have a look at following query

CREATE PROCEDURE adminsections( IN adminId INT UNSIGNED ) SELECT tbl_adminusersection.ads_name, tbl_adminusersection.ads_controller FROM tbl_adminusersectionright LEFT JOIN tbl_adminusersection ON ( tbl_adminusersectionright.adsr_ads_id = tbl_adminusersection.ads_id ) LEFT JOIN tbl_adminusers ON ( tbl_adminusersectionright.adsr_adusr_id = tbl_adminusers.admusr_id ) WHERE tbl_adminusers.admusr_id = adminId;

I know it's been eight years but I wanted to share this piece of code found in MRuby that shows how __declspec() can bee used at the same level as the export keyword.

/** Declare a public MRuby API function. */
#if defined(MRB_BUILD_AS_DLL)
#if defined(MRB_CORE) || defined(MRB_LIB)
# define MRB_API __declspec(dllexport)
#else
# define MRB_API __declspec(dllimport)
#endif
#else
# define MRB_API extern

If your cost is a polynomial, just keep the highest-order term, without its multiplier. E.g.:

O((n/2 + 1)*(n/2)) = O(n²/4 + n/2) = O(n²/4) = O(n²)

This doesn't work for infinite series, mind you. There is no single recipe for the general case, though for some common cases, the following inequalities apply:

O(log N) < O(N) < O(N log N) < O(N²) < O(N^k) < O(eⁿ) < O(n!)

I experienced the same issue when sending high volume email. Setting the deliveryMethod property to PickupDirectoryFromIis fixed it for me. Also don't create a new SmtpClient everytime.

If you want to open multiple workspaces and you are not a terminal guy, just locate the Unix executable file in your eclipse folder and click it.

The path to the said file is

Eclipse(folder) -> eclipse(right click) -> Show package Contents -> Contents -> MacOs -> eclipse(unix executable file)

Clicking on this executable will open a separate instance of eclipse.

I found a caveat that no one so far has mentioned. I don't know if it will come up often in practical situations, but here it is for the sake of completeness.

Usually, calculating a number modulo infinity returns itself as a float, but a fraction modulo infinity returns nan (not a number). Here is an example:

>>> from fractions import Fraction
>>> from math import inf
>>> 3 % inf
3.0
>>> 3.5 % inf
3.5
>>> Fraction('1/3') % inf
nan

I filed an issue on the Python bug tracker. It can be seen at https://bugs.python.org/issue32968.

Update: this will be fixed in Python 3.8.

Just to add another example:

I was replacing src attr in img html tags, but i needed to replace only the src and keep any text between the img declaration and src attribute.

I used the find+replace tool (ctrl+h) as in the image:

I have used a destructor (for debug purposes only) to see if an object was being purged from memory in the scope of a WPF application. I was unsure if garbage collection was truly purging the object from memory, and this was a good way to verify.

I provide this post for both IntelliJ and Eclipse.

Eclipse:

For making unit test for your project, please follow these steps (I am using Eclipse in order to write this test):

1- Click on New -> Java Project.

2- Write down your project name and click on finish.

3- Right click on your project. Then, click on New -> Class.

4- Write down your class name and click on finish.

Then, complete the class like this:

public class Math {
    int a, b;
    Math(int a, int b) {
        this.a = a;
        this.b = b;
    }
    public int add() {
        return a + b;
    }
}

5- Click on File -> New -> JUnit Test Case.

6- Check setUp() and click on finish. SetUp() will be the place that you initialize your test.

7- Click on OK.

8- Here, I simply add 7 and 10. So, I expect the answer to be 17. Complete your test class like this:

import org.junit.Assert;
import org.junit.Before;
import org.junit.Test;
public class MathTest {
    Math math;
    @Before
    public void setUp() throws Exception {
        math = new Math(7, 10);
    }
    @Test
    public void testAdd() {
        Assert.assertEquals(17, math.add());
    }
}

9- Write click on your test class in package explorer and click on Run as -> JUnit Test.

10- This is the result of the test.

IntelliJ: Note that I used IntelliJ IDEA community 2020.1 for the screenshots. Also, you need to set up your jre before these steps. I am using JDK 11.0.4.

1- Right-click on the main folder of your project-> new -> directory. You should call this 'test'. 2- Right-click on the test folder and create the proper package. I suggest creating the same packaging names as the original class. Then, you right-click on the test directory -> mark directory as -> test sources root. 3- In the right package in the test directory, you need to create a Java class (I suggest to use Test.java). 4- In the created class, type '@Test'. Then, among the options that IntelliJ gives you, select Add 'JUnitx' to classpath. 5- Write your test method in your test class. The method signature is like:

@Test
public void test<name of original method>(){
...
}

You can do your assertions like below:

Assertions.assertTrue(f.flipEquiv(node1_1, node2_1));

These are the imports that I added:

import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.api.Test;

This is the test that I wrote:

You can check your methods like below:

Assertions.assertEquals(<Expected>,<actual>);
Assertions.assertTrue(<actual>);
...

For running your unit tests, right-click on the test and click on Run .

If your test passes, the result will be like below:

I hope it helps. You can see the structure of the project in GitHub https://github.com/m-vahidalizadeh/problem_solving_project.

Try this

$_SERVER['HTTP_CF_CONNECTING_IP'];

instead of

$_SERVER["REMOTE_ADDR"];

It should also be noted that if you have buttons grouped together on your user form that it can link it to a different button in the group despite the one you intended being clicked.

It is a orphan branch if it has no commit.

Add an EditText on top of your listview in its .xml layout file. And in your activity/fragment..

lv = (ListView) findViewById(R.id.list_view);
    inputSearch = (EditText) findViewById(R.id.inputSearch);

// Adding items to listview
adapter = new ArrayAdapter<String>(this, R.layout.list_item, R.id.product_name,    products);
lv.setAdapter(adapter);       
inputSearch.addTextChangedListener(new TextWatcher() {

    @Override
    public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
        // When user changed the Text
        MainActivity.this.adapter.getFilter().filter(cs);
    }

    @Override
    public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) { }

    @Override
    public void afterTextChanged(Editable arg0) {}
});

The basic here is to add an OnTextChangeListener to your edit text and inside its callback method apply filter to your listview's adapter.

EDIT

To get filter to your custom BaseAdapter you"ll need to implement Filterable interface.

class CustomAdapter extends BaseAdapter implements Filterable {

    public View getView(){
    ...
    }
    public Integer getCount()
    {
    ...
    }

    @Override
    public Filter getFilter() {

        Filter filter = new Filter() {

            @SuppressWarnings("unchecked")
            @Override
            protected void publishResults(CharSequence constraint, FilterResults results) {

                arrayListNames = (List<String>) results.values;
                notifyDataSetChanged();
            }

            @Override
            protected FilterResults performFiltering(CharSequence constraint) {

                FilterResults results = new FilterResults();
                ArrayList<String> FilteredArrayNames = new ArrayList<String>();

                // perform your search here using the searchConstraint String.

                constraint = constraint.toString().toLowerCase();
                for (int i = 0; i < mDatabaseOfNames.size(); i++) {
                    String dataNames = mDatabaseOfNames.get(i);
                    if (dataNames.toLowerCase().startsWith(constraint.toString()))  {
                        FilteredArrayNames.add(dataNames);
                    }
                }

                results.count = FilteredArrayNames.size();
                results.values = FilteredArrayNames;
                Log.e("VALUES", results.values.toString());

                return results;
            }
        };

        return filter;
    }
}

Inside performFiltering() you need to do actual comparison of the search query to values in your database. It will pass its result to publishResults() method.
