I had the same error by in SQL Server Management Studio.

I found that to look at the more specific error, look at the log file created by the SQL Server. When I opened the log file, I found this error

Could not connect because the maximum number of ’2' user connections has already been reached. The system administrator can use sp_configure to increase the maximum value. The connection has been closed

I spend quite some time figuring this out. Finally running the following code fixed my problem.

sp_configure 'show advanced options', 1;
go

reconfigure
go

sp_configure 'user connections', 0
go

reconfigure
go

Edit

To view logs search for "logs" on windows startup button, click "view events logs". From there go to Applications under "Windows Logs". You can also choose "System" logs to see system wise errors. You can use filter on current logs by clicking "Filter Current Logs" on right side and then select "Error checkbox".

I had similar problem, and I solved it as folows:

I working on MS SQL 2008, but in the NH configuration I had bad dialect: NHibernate.Dialect.MsSql2005Dialect if I correct it to: NHibernate.Dialect.MsSql2008Dialect then everything's working fine without a exception "No persister for: ..." David.

  public static void main(String args[]) throws IOException{
  BufferedReader b = new BufferedReader(new InputStreamReader(System.in));
  System.out.println("Enter the decimal value:");
  String h = b.readLine();
  int k = Integer.parseInt(h);  
  String out = Integer.toBinaryString(k);
  System.out.println("Binary: " + out);
  }
}   

Try this

Console.WriteLine("\a")

Adding my two cents, based on a performance issue I observed.

If simple queries are getting parellelized unnecessarily, it can bring more problems than solving one. However, before adding MAXDOP into the query as "knee-jerk" fix, there are some server settings to check.

In Jeremiah Peschka - Five SQL Server Settings to Change, MAXDOP and "COST THRESHOLD FOR PARALLELISM" (CTFP) are mentioned as important settings to check.

Note: Paul White mentioned max server memory aslo as a setting to check, in a response to Performance problem after migration from SQL Server 2005 to 2012. A good kb article to read is Using large amounts of memory can result in an inefficient plan in SQL Server

Jonathan Kehayias - Tuning ‘cost threshold for parallelism’ from the Plan Cache helps to find out good value for CTFP.

Why is cost threshold for parallelism ignored?

Aaron Bertrand - Six reasons you should be nervous about parallelism has a discussion about some scenario where MAXDOP is the solution.

Parallelism-Inhibiting Components are mentioned in Paul White - Forcing a Parallel Query Execution Plan

I don't have enough rep points to vote up froadie's answer. But I have to disagree with the comments on Kris's answer. The following answer:

SELECT name
FROM table2
WHERE name NOT IN
    (SELECT name 
     FROM table1)

Is FAR more efficient in practice. I don't know why, but I'm running it against 800k+ records and the difference is tremendous with the advantage given to the 2nd answer posted above. Just my $0.02.

Different W3C specifications define different sets of "Node" types.

Thus, the DOM spec defines the following types of nodes:

• Document -- Element (maximum of one), ProcessingInstruction, Comment, DocumentType
• DocumentFragment -- Element, ProcessingInstruction, Comment, Text, CDATASection, EntityReference
• DocumentType -- no children
• EntityReference -- Element, ProcessingInstruction, Comment, Text, CDATASection, EntityReference
• Element -- Element, Text, Comment, ProcessingInstruction, CDATASection, EntityReference
• Attr -- Text, EntityReference
• ProcessingInstruction -- no children
• Comment -- no children
• Text -- no children
• CDATASection -- no children
• Entity -- Element, ProcessingInstruction, Comment, Text, CDATASection, EntityReference
• Notation -- no children

The XML Infoset (used by XPath) has a smaller set of nodes:

XPath has the following Node types:

• root nodes
• element nodes
• text nodes
• attribute nodes
• namespace nodes
• processing instruction nodes
• comment nodes

The answer to your question "What is the difference between an element and a node" is:

An element is a type of node. Many other types of nodes exist and serve different purposes.

You don't need jquery in order to do that.

var placeHolder="name";
var res=name.substr(name.indexOf(placeHolder) + placeHolder.length);

To expand on Ryan's answer:

Whenever setStateValues is called, React re-renders your component, which means that the function body of the StateSelector component function gets re-executed.

React docs:

setState() will always lead to a re-render unless shouldComponentUpdate() returns false.

Essentially, you're setting state with:

setStateValues(allowedState);

causing a re-render, which then causes the function to execute, and so on. Hence, the loop issue.

To illustrate the point, if you set a timeout as like:

  setTimeout(
    () => setStateValues(allowedState),
    1000
  )

Which ends the 'too many re-renders' issue.

In your case, you're dealing with a side-effect, which is handled with UseEffectin your component functions. You can read more about it here.

In entity relationship modeling, solid lines represent strong relationships and dashed lines represent weak relationships.

This is how I used this is as an example:

CAST(vAvgMaterialUnitCost.`avgUnitCost` AS DECIMAL(11,2)) * woMaterials.`qtyUsed` AS materialCost

I had android sdk and android studio installed separately in my system. Android studio had installed its own sdk. After I deleted the stand-alone android sdk, the issue of "“No system image installed for this Target” was gone.

If you want to create dynamically/runtime data table in VB.Net then you should follow these steps as mentioned below :

• Create Data table object.
• Add columns into that data table object.
• Add Rows with values into the object.

For eg.

Dim dt As New DataTable

dt.Columns.Add("Id", GetType(Integer))
dt.Columns.Add("FirstName", GetType(String))
dt.Columns.Add("LastName", GetType(String))

dt.Rows.Add(1, "Test", "data")
dt.Rows.Add(15, "Robert", "Wich")
dt.Rows.Add(18, "Merry", "Cylon")
dt.Rows.Add(30, "Tim", "Burst")

pause

will display:

Press any key to continue . . .

When your script is running, it blocks the page from doing anything. You can work around this with one of two ways:

• Use var foo = prompt("Give me input");, which will give you the string that the user enters into a popup box (or null if they cancel it)
• Split your code into two function - run one function to set up the user interface, then provide the second function as a callback that gets run when the user clicks the button.

In the simple setup you are likely using, getchar works with buffered input, so you have to press enter before getchar gets anything to read. Strings are not terminated by EOF; in fact, EOF is not really a character, but a magic value that indicates the end of the file. But EOF is not part of the string read. It's what getchar returns when there is nothing left to read.

class test
{
    void passArr()
    {
        int arr1[]={1,2,3,4,5,6,7,8,9};
        printArr(arr1);
    }

    void printArr(int[] arr2)
    {
        for(int i=0;i<arr2.length;i++)
        {
            System.out.println(arr2[i]+"  ");
        }
    }

    public static void main(String[] args)
    {
        test ob=new test();
        ob.passArr();
    }
}

when call funtion, I use: findByPlaceContaining("%" + place);

or: findByPlaceContaining(place + "%");

or: findByPlaceContaining("%" + place + "%");

You missed the * in front of NgIf (like we all have, dozens of times):

<div *ngIf="answer.accepted">&#10004;</div>

Without the *, Angular sees that the ngIf directive is being applied to the div element, but since there is no * or <template> tag, it is unable to locate a template, hence the error.

If you get this error with Angular v5:

Error: StaticInjectorError[TemplateRef]:
  StaticInjectorError[TemplateRef]:
    NullInjectorError: No provider for TemplateRef!

You may have <template>...</template> in one or more of your component templates. Change/update the tag to <ng-template>...</ng-template>.

var filePath = context.Server.MapPath(Convert.ToString(ConfigurationManager.AppSettings["ErrorLogFile"]));

var file = new FileInfo(filePath);

file.Directory.Create(); If the directory already exists, this method does nothing.

var sw = new StreamWriter(filePath, true);

sw.WriteLine(Enter your message here);

sw.Close();

The main reason you use the default queue over the main queue is to run tasks in the background.

For instance, if I am downloading a file from the internet and I want to update the user on the progress of the download, I will run the download in the priority default queue and update the UI in the main queue asynchronously.

dispatch_async(dispatch_get_global_queue( DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^(void){
    //Background Thread
    dispatch_async(dispatch_get_main_queue(), ^(void){
        //Run UI Updates
    });
});

Based on the answer of Roko C. Buljan, I have created this method which gets images from a folder and its subfolders . This might need some error handling but works fine for a simple folder structure.

var findImages = function(){
    var parentDir = "./Resource/materials/";

    var fileCrowler = function(data){
        var titlestr = $(data).filter('title').text();
        // "Directory listing for /Resource/materials/xxx"
        var thisDirectory = titlestr.slice(titlestr.indexOf('/'), titlestr.length)

        //List all image file names in the page
        $(data).find("a").attr("href", function (i, filename) {
            if( filename.match(/\.(jpe?g|png|gif)$/) ) { 
                var fileNameWOExtension = filename.slice(0, filename.lastIndexOf('.'))
                var img_html = "<img src='{0}' id='{1}' alt='{2}' width='75' height='75' hspace='2' vspace='2' onclick='onImageSelection(this);'>".format(thisDirectory + filename, fileNameWOExtension, fileNameWOExtension);
                $("#image_pane").append(img_html);
            }
            else{ 
                $.ajax({
                    url: thisDirectory + filename,
                    success: fileCrowler
                });
            }
        });}

        $.ajax({
        url: parentDir,
        success: fileCrowler
    });
}

Explicitly specifying the max_iter resolves the warning as the default max_iter is 100. [For Logistic Regression].

 logreg = LogisticRegression(max_iter=1000)

I had a scenario where nested JSON had to be serialised in a linear fashion while form data is constructed, since this is how server expects values. So, I wrote a small recursive function which translates the JSON which is like this:

{
   "orderPrice":"11",
   "cardNumber":"************1234",
   "id":"8796191359018",
   "accountHolderName":"Raj Pawan",
   "expiryMonth":"02",
   "expiryYear":"2019",
   "issueNumber":null,
   "billingAddress":{
      "city":"Wonderland",
      "code":"8796682911767",
      "firstname":"Raj Pawan",
      "lastname":"Gumdal",
      "line1":"Addr Line 1",
      "line2":null,
      "state":"US-AS",
      "region":{
         "isocode":"US-AS"
      },
      "zip":"76767-6776"
   }
}

Into something like this:

{
   "orderPrice":"11",
   "cardNumber":"************1234",
   "id":"8796191359018",
   "accountHolderName":"Raj Pawan",
   "expiryMonth":"02",
   "expiryYear":"2019",
   "issueNumber":null,
   "billingAddress.city":"Wonderland",
   "billingAddress.code":"8796682911767",
   "billingAddress.firstname":"Raj Pawan",
   "billingAddress.lastname":"Gumdal",
   "billingAddress.line1":"Addr Line 1",
   "billingAddress.line2":null,
   "billingAddress.state":"US-AS",
   "billingAddress.region.isocode":"US-AS",
   "billingAddress.zip":"76767-6776"
}

The server would accept form data which is in this converted format.

Here is the function:

function jsonToFormData (inJSON, inTestJSON, inFormData, parentKey) {
    // http://stackoverflow.com/a/22783314/260665
    // Raj: Converts any nested JSON to formData.
    var form_data = inFormData || new FormData();
    var testJSON = inTestJSON || {};
    for ( var key in inJSON ) {
        // 1. If it is a recursion, then key has to be constructed like "parent.child" where parent JSON contains a child JSON
        // 2. Perform append data only if the value for key is not a JSON, recurse otherwise!
        var constructedKey = key;
        if (parentKey) {
            constructedKey = parentKey + "." + key;
        }

        var value = inJSON[key];
        if (value && value.constructor === {}.constructor) {
            // This is a JSON, we now need to recurse!
            jsonToFormData (value, testJSON, form_data, constructedKey);
        } else {
            form_data.append(constructedKey, inJSON[key]);
            testJSON[constructedKey] = inJSON[key];
        }
    }
    return form_data;
}

Invocation:

        var testJSON = {};
        var form_data = jsonToFormData (jsonForPost, testJSON);

I am using testJSON just to see the converted results since I would not be able to extract the contents of form_data. AJAX post call:

        $.ajax({
            type: "POST",
            url: somePostURL,
            data: form_data,
            processData : false,
            contentType : false,
            success: function (data) {
            },
            error: function (e) {
            }
        });

Basically boolean represent a primitive data type where Boolean represent a reference data type. this story is started when Java want to become purely object oriented it's provided wrapper class concept to over come to use of primitive data type.

boolean b1;
Boolean b2;

b1 and b2 are not same.

From your python version output, looks like that you are using Anaconda python, in that case, there is a simple way to install tensorflow.

conda install -c conda-forge tensorflow

This command will take care of all dependencies like upgrade/downgrade etc.

You can create a global method to show message(alert) in your web form application.

public static class PageUtility
{
    public static void MessageBox(System.Web.UI.Page page,string strMsg)
    {
        //+ character added after strMsg "')"
        ScriptManager.RegisterClientScriptBlock(page, page.GetType(), "alertMessage", "alert('" + strMsg + "')", true);

    }
}

webform.aspx

protected void btnSave_Click(object sender, EventArgs e)
{
    PageUtility.MessageBox(this, "Success !");
}

If you compare it to debugging:

Stub is like making sure a method returns the correct value

Mock is like actually stepping into the method and making sure everything inside is correct before returning the correct value.

In my case, I was getting this but only on Safari Mobile. The problem is that I was using the full URL (http://example.com/whatever.php) instead of the relative one (whatever.php). This doesn't make any sense though, it can't be a XSS issue because my site is hosted at http://example.com. I guess Safari looks at the http part and automatically flags it as an insecure request without inspecting the rest of the URL.

Stumbled across this question when I was looking for a similar solution but I didn't need anything like full application level routing or more imported modules.

The following code works great for my use and requires no additional modules or imports.

  GetParam(name){
    const results = new RegExp('[\\?&]' + name + '=([^&#]*)').exec(window.location.href);
    if(!results){
      return 0;
    }
    return results[1] || 0;
  }

  PrintParams() {
    console.log('param1 = ' + this.GetParam('param1'));
    console.log('param2 = ' + this.GetParam('param2'));
  }

http://localhost:4200/?param1=hello&param2=123 outputs:

param1 = hello
param2 = 123

Test it yourself, but here's the output.

php -r '$a=array("a","b","c"); print_r($a); unset($a[1]); print_r($a);'
Array
(
    [0] => a
    [1] => b
    [2] => c
)
Array
(
    [0] => a
    [2] => c
)

You can use

Trace.WriteLine()

to write to the Output window when debugging a unit test.

document.location is deprecated in favor of window.location, which can be accessed by just location, since it's a global object.

The location object has multiple properties and methods. If you try to use it as a string then it acts like location.href.

A different approach ... here is an example: If the user has a delay of 600-1000ms when is typing you may consider he's stopped.

 myEditText.addTextChangedListener(new TextWatcher() {_x000D_
             _x000D_

C lets you use the subscript operator [] on arrays and on pointers. When you use this operator on a pointer, the resultant type is the type to which the pointer points to. For example, if you apply [] to int*, the result would be an int.

That is precisely what's going on: you are passing int*, which corresponds to a vector of integers. Using subscript on it once makes it int, so you cannot apply the second subscript to it.

It appears from your code that arr should be a 2-D array. If it is implemented as a "jagged" array (i.e. an array of pointers) then the parameter type should be int **.

Moreover, it appears that you are trying to return a local array. In order to do that legally, you need to allocate the array dynamically, and return a pointer. However, a better approach would be declaring a special struct for your 4x4 matrix, and using it to wrap your fixed-size array, like this:

// This type wraps your 4x4 matrix
typedef struct {
    int arr[4][4];
} FourByFour;
// Now rotate(m) can use FourByFour as a type
FourByFour rotate(FourByFour m) {
    FourByFour D;
    for(int i = 0; i < 4; i ++ ){
        for(int n = 0; n < 4; n++){
            D.arr[i][n] = m.arr[n][3 - i];
        }
    }
    return D;
}
// Here is a demo of your rotate(m) in action:
int main(void) {
    FourByFour S = {.arr = {
        { 1, 4, 10, 3 },
        { 0, 6, 3, 8 },
        { 7, 10 ,8, 5 },
        { 9, 5, 11, 2}
    } };
    FourByFour r = rotate(S);
    for(int i=0; i < 4; i ++ ){
        for(int n=0; n < 4; n++){
            printf("%d ", r.arr[i][n]);
        }
        printf("\n");
    }
    return 0;
}

This prints the following:

3 8 5 2 
10 3 8 11 
4 6 10 5 
1 0 7 9 

Install PIL(Python Image Library) :

then:

from PIL import Image
myImage = Image.open("your_image_here");
myImage.show();

$percentage = 50;
$totalWidth = 350;

$new_width = ($percentage / 100) * $totalWidth;

From a software tester's perspective

#pragma once is shorter than an include guard, less error prone, supported by most compilers, and some say that it compiles faster (which is not true [any longer]).

But I still suggest you go with standard #ifndef include guards.

Why #ifndef?

Consider a contrived class hierarchy like this where each of the classes A, B, and C lives inside its own file:

a.h

#ifndef A_H
#define A_H

class A {
public:
  // some virtual functions
};

#endif

b.h

#ifndef B_H
#define B_H

#include "a.h"

class B : public A {
public:
  // some functions
};

#endif

c.h

#ifndef C_H
#define C_H

#include "b.h"

class C : public B {
public:
  // some functions
};

#endif

Now let's assume you are writing tests for your classes and you need to simulate the behaviour of the really complex class B. One way to do this would be to write a mock class using for example google mock and put it inside a directory mocks/b.h. Note, that the class name hasn't changed but it's only stored inside a different directory. But what's most important is that the include guard is named exactly the same as in the original file b.h.

mocks/b.h

#ifndef B_H
#define B_H

#include "a.h"
#include "gmock/gmock.h"

class B : public A {
public:
  // some mocks functions
  MOCK_METHOD0(SomeMethod, void());
};

#endif

What's the benefit?

With this approach you can mock the behaviour of class B without touching the original class or telling C about it. All you have to do is put the directory mocks/ in the include path of your complier.

Why can't this be done with #pragma once?

If you would have used #pragma once, you would get a name clash because it cannot protect you from defining the class B twice, once the original one and once the mocked version.

In general, you can the characters of a string from i until j with string[i:j]. string[:2] is shorthand for string[0:2]. This works for arrays as well.

Learn about python's slice notation at the official tutorial

explode('.', $string)

If you know your string has a fixed number of components you could use something like

list($a, $b) = explode('.', 'object.attribute');
echo $a;
echo $b;

Prints:

object
attribute

It can be:

echo "Welcome".$_POST['firstname'].$_POST['lastname'];

            public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

               //check if spinner1 has a selected item and show the value in edittext


            }

            @Override
            public void onNothingSelected(AdapterView<?> parent) {

               // sometimes you need nothing here
            }
        });

Mathematically, to get percentage from two numbers:

percentage = (yourNumber / totalNumber) * 100;

And also, to calculate from a percentage :

number = (percentage / 100) * totalNumber;

Your schema is for its target namespace http://www.example.org/Test so it defines an element with name MyElement in that target namespace http://www.example.org/Test. Your instance document however has an element with name MyElement in no namespace. That is why the validating parser tells you it can't find a declaration for that element, you haven't provided a schema for elements in no namespace.

You either need to change the schema to not use a target namespace at all or you need to change the instance to use e.g. <MyElement xmlns="http://www.example.org/Test">A</MyElement>.

Function makeRed and makeBlack use queue and dequeue to execute each other. The effect is that, the '#wow' element blinks continuously.

<html>
  <head>
    <script src="http://code.jquery.com/jquery-1.9.1.js"></script>
    <script type="text/javascript">
      $(document).ready(function(){
          $('#wow').click(function(){
            $(this).delay(200).queue(makeRed);
            });
          });

      function makeRed(){
        $('#wow').css('color', 'red');
        $('#wow').delay(200).queue(makeBlack);
        $('#wow').dequeue();
      }

      function makeBlack(){
        $('#wow').css('color', 'black');
        $('#wow').delay(200).queue(makeRed);
        $('#wow').dequeue();

I had the exact same problem. The way I solved it on Mac is this:

1. Switch to jenkins user (sudo -iu jenkins)
2. Run: ssh-keygen (Note - You are creating ssh key pairs for jenkins user now. You should see something like this : Enter file in which to save the key (/Users/Shared/Jenkins/.ssh/id_rsa):
3. Keep pressing Enter for default value till end
4. Run the command showing in the Jenkins error message, on your teminal (eg : "git ls-remote -h [email protected]:adolfosrs/jenkins-test.git HEAD")
5. You will be asked if you want to continue. Say yes
6. The Github repo will be added to your known_hosts file in : /Users/Shared/Jenkins/.ssh/
7. Go back to Jenkins portal and try your Github SSH url
8. It should work. Good Luck

I have the same problem. It is caused by a screen capture software hypersnap7. So I think the hotkey conflict is the reason. Reboot computer, don't start other software, start Android Development Tools and watch which software triger the bug.

This answer deals with your question but is not exactly an answer to it. =) It's an interesting library I found out recently and I want to share with you.

Project Lombok can generate common methods, such as getters, setters, equals() and hashCode(), toString(), for your classes automatically. It replaces them with annotations reducing boilerplate code. To see a good example of code written using Lombok watch a video on the main page or read this article.

Android development with Lombok is easy and won't make your android application any 'heavier' because Lombok is a compile-time only library. It is important to configure your Android project properly.

Another example:

import lombok.Getter;
import lombok.Setter;

public class Profile {

  @Getter @Setter
  private String username;

  @Getter @Setter
  private String password;

}

Android development with Lombok is possible. Lombok should be a compile-time only dependency, as otherwise the entirety of Lombok will end up in your DEX files, wasting precious space. Gradle snippet:

dependencies {
    compileOnly "org.projectlombok:lombok:1.16.18"
}

In addition you may want to add the Lombok IntelliJ plugin to support Lombok features in your IDE at development time. Also there is Hrisey library which is based on Lombok. Simply put, it's Lombok + Parcellable support.

Try this: TO_DATE('2011-07-28T23:54:14Z', 'YYYY-MM-DD"T"HH24:MI:SS"Z"')

As mentioned, you can use:

=Format(Fields!Price.Value, "C")

A digit after the "C" will specify precision:

=Format(Fields!Price.Value, "C0")
=Format(Fields!Price.Value, "C1")

You can also use Excel-style masks like this:

=Format(Fields!Price.Value, "#,##0.00")

Haven't tested the last one, but there's the idea. Also works with dates:

=Format(Fields!Date.Value, "yyyy-MM-dd")

$('div').html('');

But why are you clearing, divToUpdate.html(data); will completely replace the old HTML.

Your response should be something like this to be qualified as Json Array.

{
  "songs":[
    {"2562862600": {"id":"2562862600", "pos":1}},  
    {"2562862620": {"id":"2562862620", "pos":1}},  
    {"2562862604": {"id":"2562862604", "pos":1}},  
    {"2573433638": {"id":"2573433638", "pos":1}}
  ]
}

You can parse your response as follows

String resp = ...//String output from your source
JSONObject ob = new JSONObject(resp);  
JSONArray arr = ob.getJSONArray("songs");

for(int i=0; i<arr.length(); i++){   
  JSONObject o = arr.getJSONObject(i);  
  System.out.println(o);  
}

• It is a very easy to use method in C++11.
• We can use std::chrono::high_resolution_clock from header
• We can write a method to print the method execution time in a much readable form.

For example, to find the all the prime numbers between 1 and 100 million, it takes approximately 1 minute and 40 seconds. So the execution time get printed as:

Execution Time: 1 Minutes, 40 Seconds, 715 MicroSeconds, 715000 NanoSeconds

The code is here:

#include <iostream>
#include <chrono>

using namespace std;
using namespace std::chrono;

typedef high_resolution_clock Clock;
typedef Clock::time_point ClockTime;

void findPrime(long n, string file);
void printExecutionTime(ClockTime start_time, ClockTime end_time);

int main()
{
    long n = long(1E+8);  // N = 100 million

    ClockTime start_time = Clock::now();

    // Write all the prime numbers from 1 to N to the file "prime.txt"
    findPrime(n, "C:\\prime.txt"); 

    ClockTime end_time = Clock::now();

    printExecutionTime(start_time, end_time);
}

void printExecutionTime(ClockTime start_time, ClockTime end_time)
{
    auto execution_time_ns = duration_cast<nanoseconds>(end_time - start_time).count();
    auto execution_time_ms = duration_cast<microseconds>(end_time - start_time).count();
    auto execution_time_sec = duration_cast<seconds>(end_time - start_time).count();
    auto execution_time_min = duration_cast<minutes>(end_time - start_time).count();
    auto execution_time_hour = duration_cast<hours>(end_time - start_time).count();

    cout << "\nExecution Time: ";
    if(execution_time_hour > 0)
    cout << "" << execution_time_hour << " Hours, ";
    if(execution_time_min > 0)
    cout << "" << execution_time_min % 60 << " Minutes, ";
    if(execution_time_sec > 0)
    cout << "" << execution_time_sec % 60 << " Seconds, ";
    if(execution_time_ms > 0)
    cout << "" << execution_time_ms % long(1E+3) << " MicroSeconds, ";
    if(execution_time_ns > 0)
    cout << "" << execution_time_ns % long(1E+6) << " NanoSeconds, ";
}

Using the second form gives you a variable (named based upon the as clause, in your example e) in the except block scope with the exception object bound to it so you can use the infomration in the exception (type, message, stack trace, etc) to handle the exception in a more specially tailored manor.

foreach ($tmpArray as $innerArray) {
    //  Check type
    if (is_array($innerArray)){
        //  Scan through inner loop
        foreach ($innerArray as $value) {
            echo $value;
        }
    }else{
        // one, two, three
        echo $innerArray;
    }
}

In my scenario, there was no process blocking the database under sp_who2. However, we discovered because the database is much larger than our other databases that pending processes were still running which is why the database under the availability group still displayed as red/offline after we tried to 'resume data'by right clicking the paused database.

To check if you still have processes running just execute this command: select percent complete from sys.dm_exec_requests where percent_complete > 0

I don't know any Windows specific function. You could try getting the MD5 hash of the file every second/minute/hour (depends on how fast you need it) and compare it to the last hash. When it differs you know the file has been changed and you read out the newest lines.

Here is what I do in an activity for buffered reading extend/modify to match your needs

BufferedReader reader = null;
try {
    reader = new BufferedReader(
        new InputStreamReader(getAssets().open("filename.txt")));

    // do reading, usually loop until end of file reading  
    String mLine;
    while ((mLine = reader.readLine()) != null) {
       //process line
       ...
    }
} catch (IOException e) {
    //log the exception
} finally {
    if (reader != null) {
         try {
             reader.close();
         } catch (IOException e) {
             //log the exception
         }
    }
}

EDIT : My answer is perhaps useless if your question is on how to do it outside of an activity. If your question is simply how to read a file from asset then the answer is above.

UPDATE :

To open a file specifying the type simply add the type in the InputStreamReader call as follow.

BufferedReader reader = null;
try {
    reader = new BufferedReader(
        new InputStreamReader(getAssets().open("filename.txt"), "UTF-8")); 

    // do reading, usually loop until end of file reading 
    String mLine;
    while ((mLine = reader.readLine()) != null) {
       //process line
       ...
    }
} catch (IOException e) {
    //log the exception
} finally {
    if (reader != null) {
         try {
             reader.close();
         } catch (IOException e) {
             //log the exception
         }
    }
}

EDIT

As @Stan says in the comment, the code I am giving is not summing up lines. mLine is replaced every pass. That's why I wrote //process line. I assume the file contains some sort of data (i.e a contact list) and each line should be processed separately.

In case you simply want to load the file without any kind of processing you will have to sum up mLine at each pass using StringBuilder() and appending each pass.

ANOTHER EDIT

According to the comment of @Vincent I added the finally block.

Also note that in Java 7 and upper you can use try-with-resources to use the AutoCloseable and Closeable features of recent Java.

CONTEXT

In a comment @LunarWatcher points out that getAssets() is a class in context. So, if you call it outside of an activity you need to refer to it and pass the context instance to the activity.

ContextInstance.getAssets();

This is explained in the answer of @Maneesh. So if this is useful to you upvote his answer because that's him who pointed that out.

I do this to post a delayed runnable:

myHandler.postDelayed(myRunnable, SPLASH_DISPLAY_LENGTH); 

And this to remove it: myHandler.removeCallbacks(myRunnable);

Try this in your code:

import Foo from './Foo';
import Bar from './Bar';

// without default
export {
  Foo,
  Bar,
}

Btw, you can also do it this way:

// bundle.js
export { default as Foo } from './Foo'
export { default as Bar } from './Bar'
export { default } from './Baz'

// and import somewhere..
import Baz, { Foo, Bar } from './bundle'

Using export

export const MyFunction = () => {}
export const MyFunction2 = () => {}

const Var = 1;
const Var2 = 2;

export {
   Var,
   Var2,
}


// Then import it this way
import {
  MyFunction,
  MyFunction2,
  Var,
  Var2,
} from './foo-bar-baz';

The difference with export default is that you can export something, and apply the name where you import it:

// export default
export default class UserClass {
  constructor() {}
};

// import it
import User from './user'

$('#datetimepicker').datetimepicker({ 
    minView: 2, 
    pickTime: false, 
    language: 'pt-BR' 
});

Please try if it works for you as well

A memory heap is a location in memory where memory may be allocated at random access.
Unlike the stack where memory is allocated and released in a very defined order, individual data elements allocated on the heap are typically released in ways which is asynchronous from one another. Any such data element is freed when the program explicitly releases the corresponding pointer, and this may result in a fragmented heap. In opposition only data at the top (or the bottom, depending on the way the stack works) may be released, resulting in data element being freed in the reverse order they were allocated.

Maybe something changed since 2011 but this worked for me:

$ date +"%Y%m%d"
20150330

No need for the -d to get the same appearing result.

Using canvas to display Videos

Displaying a video is much the same as displaying an image. The minor differences are to do with onload events and the fact that you need to render the video every frame or you will only see one frame not the animated frames.

The demo below has some minor differences to the example. A mute function (under the video click mute/sound on to toggle sound) and some error checking to catch IE9+ and Edge if they don't have the correct drivers.

The previous answers by user372551 is out of date (December 2010) and has a flaw in the rendering technique used. It uses the setTimeout and a rate of 33.333..ms which setTimeout will round down to 33ms this will cause the frames to be dropped every two seconds and may drop many more if the video frame rate is any higher than 30. Using setTimeout will also introduce video shearing created because setTimeout can not be synced to the display hardware.

There is currently no reliable method that can determine a videos frame rate unless you know the video frame rate in advance you should display it at the maximum display refresh rate possible on browsers. 60fps

The given top answer was for the time (6 years ago) the best solution as requestAnimationFrame was not widely supported (if at all) but requestAnimationFrame is now standard across the Major browsers and should be used instead of setTimeout to reduce or remove dropped frames, and to prevent shearing.

The example demo.

Loads a video and set it to loop. The video will not play until the you click on it. Clicking again will pause. There is a mute/sound on button under the video. The video is muted by default.

Note users of IE9+ and Edge. You may not be able to play the video format WebM as it needs additional drivers to play the videos. They can be found at tools.google.com Download IE9+ WebM support

in swift 4 to convert to url use URL

let fileUrl = URL.init(fileURLWithPath: filePath)

or

let fileUrl = URL(fileURLWithPath: filePath)

In C++ it is easy.

std::copy(someStr.c_str(), someStr.c_str()+n, std::ostream_iterator<char>(std::cout, ""));

EDIT: It is also safer to use this with string iterators, so you don't run off the end. I'm not sure what happens with printf and string that are too short, but I'm guess this may be safer.

I changed Scanner fin = new Scanner(file); to Scanner fin = new Scanner(new File(file)); and it works perfectly now. I didn't think the difference mattered but there you go.

View divider = d.findViewById(dividerId);
divider.setBackgroundColor(getResources().getColor(R.color.my_color));

You can find more dialog's ids in alert_dialog.xml file. Eg. android:id/alertTitle for changing title color...

UPDATE: Title color

Hack for changing title color:

int textViewId = d.getContext().getResources().getIdentifier("android:id/alertTitle", null, null);
TextView tv = (TextView) d.findViewById(textViewId);
tv.setTextColor(getResources().getColor(R.color.my_color));

<div id="myInfoDiv" seamless="seamless" scrolling="no" style="width:100%; height: 100%; float: left; color: #FFF; background:#ed8719; line-height:100%; font-size:100%; font-family: sans-serif>;

Use the above div and it will not show scroll bar in any browser.

Unicode is an agreed-upon format for the binary representation of characters and various kinds of formatting (e.g. lower case/upper case, new line, carriage return), and other "things" (e.g. emojis). A computer is no less capable of storing a unicode representation (a series of bits), whether in memory or in a file, than it is of storing an ascii representation (a different series of bits), or any other representation (series of bits).

For communication to take place, the parties to the communication must agree on what representation will be used.

Because unicode seeks to represent all the possible characters (and other "things") used in inter-human and inter-computer communication, it requires a greater number of bits for the representation of many characters (or things) than other systems of representation that seek to represent a more limited set of characters/things. To "simplify," and perhaps to accommodate historical usage, unicode representation is almost exclusively converted to some other system of representation (e.g. ascii) for the purpose of storing characters in files.

It is not the case that unicode cannot be used for storing characters in files, or transmitting them through any communications channel, simply that it is not.

The term "string," is not precisely defined. "String," in its common usage, refers to a set of characters/things. In a computer, those characters may be stored in any one of many different bit-by-bit representations. A "byte string" is a set of characters stored using a representation that uses eight bits (eight bits being referred to as a byte). Since, these days, computers use the unicode system (characters represented by a variable number of bytes) to store characters in memory, and byte strings (characters represented by single bytes) to store characters to files, a conversion must be used before characters represented in memory will be moved into storage in files.

The best that I've been able to do is

$(this).closest('.modal').modal('toggle');

This gets the modal holding the DOM object you triggered the event on (guessing you're clicking a button). Gets the closest parent '.modal' and toggles it. Obviously only works because it's inside the modal you clicked.

You can however do this:

$(".modal:visible").modal('toggle');

This gets the modal that is displaying (since you can only have one open at a time), and triggers the 'toggle' This would not work without ":visible"

I have pieced together the following that is hopefully simpler and cleaner than some of the existing answers and uses only the AWS CLI and no additional tools.

This code example shows how to get the value of tag 'myTag' for the current EC2 instance:

Using describe-tags:

export AWS_DEFAULT_REGION=us-east-1
instance_id=$(curl -s http://169.254.169.254/latest/meta-data/instance-id)
aws ec2 describe-tags \
  --filters "Name=resource-id,Values=$instance_id" 'Name=key,Values=myTag' \
  --query 'Tags[].Value' --output text

Or, alternatively, using describe-instances:

aws ec2 describe-instances --instance-id $instance_id \
  --query 'Reservations[].Instances[].Tags[?Key==`myTag`].Value' --output text

Look up the new HTML5 Input Types. These instruct browsers to perform client-side filtering of data, but the implementation is incomplete across different browsers. The pattern attribute will do regex-style filtering, but, again, browsers don't fully (or at all) support it.

However, these won't block the input itself, it will simply prevent submitting the form with the invalid data. You'll still need to trap the onkeydown event to block key input before it displays on the screen.

Using .Equals is also a lot easier to read.

Use setImmediate if you want to queue the function behind whatever I/O event callbacks that are already in the event queue. Use process.nextTick to effectively queue the function at the head of the event queue so that it executes immediately after the current function completes.

So in a case where you're trying to break up a long running, CPU-bound job using recursion, you would now want to use setImmediate rather than process.nextTick to queue the next iteration as otherwise any I/O event callbacks wouldn't get the chance to run between iterations.

To answer your question. I would say it's fairly common for applications to replace spaces in values that will be used in URLs. The reason for this is ussually to avoid the more difficult to read percent (URI) encoding that occurs.

Check out this wikipedia article about Percent-encoding.

var pinIcon = new google.maps.MarkerImage(
    "http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|00D900",
    null, /* size is determined at runtime */
    null, /* origin is 0,0 */
    null, /* anchor is bottom center of the scaled image */
    new google.maps.Size(12, 18)
);

Use HttpUrlConnection by calling openConnection() on your URL object.

getResponseCode() will give you the HTTP response once you've read from the connection.

e.g.

   URL u = new URL("http://www.example.com/"); 
   HttpURLConnection huc = (HttpURLConnection)u.openConnection(); 
   huc.setRequestMethod("GET"); 
   huc.connect() ; 
   OutputStream os = huc.getOutputStream(); 
   int code = huc.getResponseCode(); 

(not tested)

Sometimes it may be required to execute the update atomically that is using one update request to the database without reading it first.

Also get-set attribute-save may cause problems if such updates may be done concurrently or if you need to set the new value based on the old field value.

In such cases query expressions together with update may by useful:

TemperatureData.objects.filter(id=1).update(value=F('value') + 1)

I got this on Firefox (FF58). I fixed this with:

1. It is still experimental on Firefox (from v54): You have to set to true the variable dom.moduleScripts.enabled in about:config

Source: Import page on mozilla (See Browser compatibility)

2. Add type="module" to your script tag where you import the js file

<script type="module" src="appthatimports.js"></script>

3. Import files have to be prefixed (./, /, ../ or http:// before)

import * from "./mylib.js"

For more examples, this blog post is good.

For react-router v3.x

I had the same issue where I needed a confirmation message for any unsaved change on the page. In my case, I was using React Router v3, so I could not use <Prompt />, which was introduced from React Router v4.

I handled 'back button click' and 'accidental link click' with the combination of setRouteLeaveHook and history.pushState(), and handled 'reload button' with onbeforeunload event handler.

setRouteLeaveHook (doc) & history.pushState (doc)

• Using only setRouteLeaveHook was not enough. For some reason, the URL was changed although the page remained the same when 'back button' was clicked.

    // setRouteLeaveHook returns the unregister method
    this.unregisterRouteHook = this.props.router.setRouteLeaveHook(
      this.props.route,
      this.routerWillLeave
    );
  
    ...
  
    routerWillLeave = nextLocation => {
      // Using native 'confirm' method to show confirmation message
      const result = confirm('Unsaved work will be lost');
      if (result) {
        // navigation confirmed
        return true;
      } else {
        // navigation canceled, pushing the previous path
        window.history.pushState(null, null, this.props.route.path);
        return false;
      }
    };
  

onbeforeunload (doc)

• It is used to handle 'accidental reload' button

  window.onbeforeunload = this.handleOnBeforeUnload;
  
  ...
  
  handleOnBeforeUnload = e => {
    const message = 'Are you sure?';
    e.returnValue = message;
    return message;
  }
  

Below is the full component that I have written

• note that withRouter is used to have this.props.router.
• note that this.props.route is passed down from the calling component

• note that currentState is passed as prop to have initial state and to check any change

  import React from 'react';
  import PropTypes from 'prop-types';
  import _ from 'lodash';
  import { withRouter } from 'react-router';
  import Component from '../Component';
  import styles from './PreventRouteChange.css';

    constructor(props) {
      super(props);
      this.state = {
        // initialize the initial state to check any change
        initialState: _.cloneDeep(props.currentState),
        hookMounted: false
      };
    }
  
    componentDidUpdate() {
  
     // I used the library called 'lodash'
     // but you can use your own way to check any unsaved changed
      const unsaved = !_.isEqual(
        this.state.initialState,
        this.props.currentState
      );
  
      if (!unsaved && this.state.hookMounted) {
        // unregister hooks
        this.setState({ hookMounted: false });
        this.unregisterRouteHook();
        window.onbeforeunload = null;
      } else if (unsaved && !this.state.hookMounted) {
        // register hooks
        this.setState({ hookMounted: true });
        this.unregisterRouteHook = this.props.router.setRouteLeaveHook(
          this.props.route,
          this.routerWillLeave
        );
        window.onbeforeunload = this.handleOnBeforeUnload;
      }
    }
  
    componentWillUnmount() {
      // unregister onbeforeunload event handler
      window.onbeforeunload = null;
    }
  
    handleOnBeforeUnload = e => {
      const message = 'Are you sure?';
      e.returnValue = message;
      return message;

try to add this section in your web.config file on web server, sometimes it happens with php pages:

<httpProtocol>
    <customHeaders>
        <clear />
        <add name="X-UA-Compatible" value="IE=edge" />
    </customHeaders>
</httpProtocol>

You need to use the overflow option, but with the following parameters:

.nav {
    max-height:300px;
    overflow-y:auto;  
}

Use overflow-y:auto; so the scrollbar only appears when the content exceeds the maximum height.

If you use overflow-y:scroll, the scrollbar will always be visible - on all .nav - regardless if the content exceeds the maximum heigh or not.

Presumably you want something that adapts itself to the content rather then the the opposite.

Hope it may helpful

Given this example url:

http://www.example.com/some-dir/yourpage.php?q=bogus&n=10

$_SERVER['REQUEST_URI'] will give you:

/some-dir/yourpage.php?q=bogus&n=10

Whereas $_GET['q'] will give you:

bogus

In other words, $_SERVER['REQUEST_URI'] will hold the full request path including the querystring. And $_GET['q'] will give you the value of parameter q in the querystring.

For my project, I have a requirement to be able to build to both x86 and x64. The problem with this is that whenever you add references while using one, then it complains when you build the other.

My solution is to manually edit the *.csproj files so that lines like these:

<Reference Include="MyLibrary.MyNamespace, Version=1.0.0.0, Culture=neutral, processorArchitecture=x86"/>

<Reference Include="MyLibrary.MyNamespace, Version=1.0.0.0, Culture=neutral, processorArchitecture=AMD64"/>

<Reference Include="MyLibrary.MyNamespace, Version=1.0.0.0, Culture=neutral, processorArchitecture=MSIL"/>

get changed to this:

<Reference Include="MyLibrary.MyNamespace, Version=1.0.0.0, Culture=neutral"/>

Go to wherever you installed Android Studio (for me it's under C:\Users\username\AppData\Local\Android\android-studio\) and open sdk\tools, then run android.bat. From here, update and download any missing build-tools and make sure you update the Android Support Repository and Android Support Library under Extras. Restart Android Studio after the SDK Manager finishes.

It seems that Android Studio completely ignores any installed Android SDK files and keeps a copy of its own. After running an update, everything compiled successfully for me using compile com.android.support:appcompat-v7:18.0.+

You can try open MVG library, It can be used for multiple interfaces too.

As you know JBoss is a purely filesystem based installation. To install you simply unzip a file and thats it. Once you install a certain folder structure is created by default and as you run the JBoss instance for the first time, it creates additional folders for runtime operation. For comparison here is the structure of JBoss AS 7 before and after you start for the first time

Before

jboss-as-7
 |
 |---> standalone
 |      |----> lib
 |      |----> configuration
 |      |----> deployments
 |      
 |---> domain
 |....

After

jboss-as-7
     |
     |---> standalone
     |      |----> lib
     |      |----> configuration
     |      |----> deployments
     |      |----> tmp
     |      |----> data
     |      |----> log
     |      
     |---> domain
     |....

As you can see 3 new folders are created (log, data & tmp). These folders can all be deleted without effecting the application deployed in deployments folder unless your application generated Data that's stored in those folders. In development, its ok to delete all these 3 new folders assuming you don't have any need for the logs and data stored in "data" directory.

For production, ITS NOT RECOMMENDED to delete these folders as there maybe application generated data that stores certain state of the application. For ex, in the data folder, the appserver can save critical Tx rollback logs. So contact your JBoss Administrator if you need to delete those folders for any reason in production.

Good luck!

The Scriptler Groovy script doesn't seem to get all the environment variables of the build. But what you can do is force them in as parameters to the script:

1. When you add the Scriptler build step into your job, select the option "Define script parameters"

2. Add a parameter for each environment variable you want to pass in. For example "Name: JOB_NAME", "Value: $JOB_NAME". The value will get expanded from the Jenkins build environment using '$envName' type variables, most fields in the job configuration settings support this sort of expansion from my experience.

3. In your script, you should have a variable with the same name as the parameter, so you can access the parameters with something like:

   println "JOB_NAME = $JOB_NAME"

I haven't used Sciptler myself apart from some experimentation, but your question posed an interesting problem. I hope this helps!

Swift 4.2 version of @KiritModi answer

func resizeImage(image: UIImage, targetSize: CGSize) -> UIImage {
    let size = image.size

    let widthRatio  = targetSize.width  / size.width
    let heightRatio = targetSize.height / size.height

    var newSize: CGSize
    if(widthRatio > heightRatio) {
        newSize = CGSize(width: size.width * heightRatio, height: size.height * heightRatio)
    } else {
        newSize = CGSize(width: size.width * widthRatio, height: size.height *      widthRatio)
    }

    let rect = CGRect(x: 0, y: 0, width: newSize.width, height: newSize.height)

    UIGraphicsBeginImageContextWithOptions(newSize, false, 1.0)
    image.draw(in: rect)
    let newImage = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()

    return newImage!
}

To settext in any of in activity than use this below code... Follow these step one by one:

1.Declare

    private TextView event_post;

2.Bind this

    event_post = (TextView) findViewById(R.id.text_post);

3.SetText in

    event_post.setText(event_post_count);

another option is to define Scanner input = new Scanner(System.in); inside the try block, this will create a new object each time you need to re-enter the values.

I used a great deal of math when I was solving problems in solid mechanics and heat transfer using computers. Linear algebra, numerical methods, etc.

I never tap into any of that knowledge now that I'm writing business applications that deliver information from relational databases to web-based user interfaces.

I still would recommend a better math background to anyone.

Discrete math is very helpful to a developer; I have no formal training in it.

I think the techniques laid out in "Programming Collective Intelligence" are far from the stuff I did as an ME and could fall into the business apps that I'm doing now. Netflix has certainly made a nice business out of it. This group intelligence stuff appears to be on the rise.

To point your apex/root/naked domain at a Heroku-hosted application, you'll need to use a DNS provider who supports CNAME-like records (often referred to as ALIAS or ANAME records). Currently Heroku recommends:

• ALIAS at DNSimple
• ANAME at DNS Made Easy
• ANAME at easyDNS
• ALIAS at PointDNS
• CNAME at CloudFlare

Whichever of those you choose, your record will look like the following:

Record: ALIAS or ANAME

Name: empty or @

Target: example.com.herokudns.com.

That's all you need.

However, it's not good for SEO to have both the www version and non-www version resolve. One should point to the other as the canonical URL. How you decide to do that depends on if you're using HTTPS or not. And if you're not, you probably should be as Heroku now handles SSL certificates for you automatically and for free for all applications running on paid dynos.

If you're not using HTTPS, you can just set up a 301 Redirect record with most DNS providers pointing name www to http://example.com.

If you are using HTTPS, you'll most likely need to handle the redirection at the application level. If you want to know why, check out these short and long explanations but basically since your DNS provider or other URL forwarding service doesn't have, and shouldn't have, your SSL certificate and private key, they can't respond to HTTPS requests for your domain.

To handle the redirects at the application level, you'll need to:

• Add both your apex and www host names to the Heroku application (heroku domains:add example.com and heroku domains:add www.example.com)
• Set up your SSL certificates
• Point your apex domain record at Heroku using an ALIAS or ANAME record as described above
• Add a CNAME record with name www pointing to www.example.com.herokudns.com.
• And then in your application, 301 redirect any www requests to the non-www URL (here's an example of how to do it in Django)
• Also in your application, you should probably redirect any HTTP requests to HTTPS (for example, in Django set SECURE_SSL_REDIRECT to True)

Use the after method on the Tk object:

from tkinter import *

root = Tk()

def task():
    print("hello")
    root.after(2000, task)  # reschedule event in 2 seconds

root.after(2000, task)
root.mainloop()

Here's the declaration and documentation for the after method:

def after(self, ms, func=None, *args):
    """Call function once after given time.

    MS specifies the time in milliseconds. FUNC gives the
    function which shall be called. Additional parameters
    are given as parameters to the function call.  Return
    identifier to cancel scheduling with after_cancel."""

sep='\t' is often used for Tab-delimited file.

On the other hand, referring to a different blogging Scott (Watermasyck, of Telligent) - they found that most users could speed up the websites (using Telligent's Community Server), by putting the database on the same machine as the web site. However, in their customer's case, usually the db & web server are the only applications on that machine, and the website isn't straining the machine that much. Then, the efficiency of not having to send data across the network more that made up for the increased strain.

To view the log file, you can use "C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\SvcTraceViewer.exe".

You don't have to install the entire thing, just the ".NET Development / Tools" part.

When/if it bombs out during installation with a non-sensical error, Petopas' answer to Windows 7 SDK Installation Failure solved my issue.

I think your answer can be found on this page. From the page:

PropagationFlags.None

If you don't want to install the cors library and instead want to fix your original code, the other step you are missing is that Access-Control-Allow-Origin:* is wrong. When passing Authentication tokens (e.g. JWT) then you must explicitly state every url that is calling your server. You can't use "*" when doing authentication tokens.

I have found an excellent and relatively short explanation here.

A multipart request is a REST request containing several packed REST requests inside its entity.

start "" "c:\path with spaces\app.exe" "C:\path parameter\param.exe"

When I used above suggestion, I've got:

'c:\path' is not recognized a an internal or external command, operable program or batch file.

I think second qoutation mark prevent command to run. After some search below solution save my day:

start "" CALL "c:\path with spaces\app.exe" "C:\path parameter\param.exe"

class is a keyword that is used only* to introduce class definitions. When you declare new class instances either as local objects or as function parameters you use only the name of the class (which must be in scope) and not the keyword class itself.

e.g.

class ANewType
{
    // ... details
};

This defines a new type called ANewType which is a class type.

You can then use this in function declarations:

void function(ANewType object);

You can then pass objects of type ANewType into the function. The object will be copied into the function parameter so, much like basic types, any attempt to modify the parameter will modify only the parameter in the function and won't affect the object that was originally passed in.

If you want to modify the object outside the function as indicated by the comments in your function body you would need to take the object by reference (or pointer). E.g.

void function(ANewType& object); // object passed by reference

This syntax means that any use of object in the function body refers to the actual object which was passed into the function and not a copy. All modifications will modify this object and be visible once the function has completed.

[* The class keyword is also used in template definitions, but that's a different subject.]

See jQuery.scroll(). You can bind this to the window element to get your desired event hook.

On scroll, then simply check your scroll position:

$(window).scroll(function() {
  var scrollTop = $(window).scrollTop();
  if ( scrollTop > $(headerElem).offset().top ) { 
    // display add
  }
});

$.browser was removed from jQuery starting with version 1.9. It is now available as a plugin. It's generally recommended to avoid browser detection, which is why it was removed.

To answer your question, yes you may pass JSON in the URI as part of a GET request (provided you URL-encode). However, considering your reason for doing this is due to the length of the URI, using JSON will be self-defeating (introducing more characters than required).

I suggest you send your parameters in body of a POST request, either in regular CGI style (param1=val1&param2=val2) or JSON (parsed by your API upon receipt)

I faced the very same error when I was trying to connect to my SQL Server 2014 instance using sa user using SQL Server Management Studio (SSMS). I was facing this error even when security settings for sa user was all good and SQL authentication mode was enabled on the SQL Server instance.

Finally, the issue turned out to be that Named Pipes protocol was disabled. Here is how you can enable it:

Open SQL Server Configuration Manager application from start menu. Now, enable Named Pipes protocol for both Client Protocols and Protocols for <SQL Server Instance Name> nodes as shown in the snapshot below:

Note: Make sure you restart the SQL Server instance after making changes.

P.S. I'm not very sure but there is a possibility that the Named Pipes enabling was required under only one of the two nodes that I've advised. So you can try it one after the other to reach to a more precise solution.

I know the Q is not about Firefox but I did not want to add a copy of this question to just answer it myself.

For Firefox you need to add debugger; to be able to do what @matt-ball suggested for the script tag.

So on your code, you add debugger above the line you want to debug and then you can add breakpoints. If you just set the breakpoints on the browser it won't stop.

If this is not the place to add a Firefox answer given that the question is about Chrome. Don't :( minus the answer just let me know where I should post it and I'll happily move the post. :)

Use OpenCSV for reliability. Split should never be used for these kind of things. Here's a snippet from a program of my own, it's pretty straightforward. I check if a delimiter character was specified and use this one if it is, if not I use the default in OpenCSV (a comma). Then i read the header and fields

CSVReader reader = null;
try {
    if (delimiter > 0) {
        reader = new CSVReader(new FileReader(this.csvFile), this.delimiter);
    }
    else {
        reader = new CSVReader(new FileReader(this.csvFile));
    }

    // these should be the header fields
    header = reader.readNext();
    while ((fields = reader.readNext()) != null) {
        // more code
    }
catch (IOException e) {
    System.err.println(e.getMessage());
}

To get the form that the submit is inside why not just

this.form

Easiest & quickest path to the result.

Using Request.Url.Host is appropriate - it's how you retrieve the value of the HTTP Host: header, which specifies which hostname (domain name) the UA (browser) wants, as the Resource-path part of the HTTP request does not include the hostname.

Note that localhost:5858 is not a domain name, it is an endpoint specifier, also known as an "authority", which includes the hostname and TCP port number. This is retrieved by accessing Request.Uri.Authority.

Furthermore, it is not valid to get somedomain.com from www.somedomain.com because a webserver could be configured to serve a different site for www.somedomain.com compared to somedomain.com, however if you are sure this is valid in your case then you'll need to manually parse the hostname, though using String.Split('.') works in a pinch.

Note that webserver (IIS) configuration is distinct from ASP.NET's configuration, and that ASP.NET is actually completely ignorant of the HTTP binding configuration of the websites and web-applications that it runs under. The fact that both IIS and ASP.NET share the same configuration files (web.config) is a red-herring.

echo "Enter Drive letter" 
set /p driveletter=

I assume you want to center them on one line and not on two separate lines based on your fiddle. If that is the case, try the following css:

 div { background:red;
      overflow:hidden;
}
span { display:block;
       margin:0 auto;
       width:200px;
}
span a { padding:5px 10px;
         color:#fff;
         background:#222;
}

I removed the float since you want to center it, and then made the span surrounding the links centered by adding margin:0 auto to them. Finally, I added a static width to the span. This centers the links on one line within the red div.

For those of you who prefer a quick and dirty approach, just list all the columns that together define a unique record and create a unique index with those columns, like so:

ALTER IGNORE TABLE TABLE_NAME ADD UNIQUE (column1,column2,column3)

You can drop the unique index afterwords.

You'll need a datasource for working with JdbcTemplate.

JdbcTemplate template = new JdbcTemplate(yourDataSource);

template.update(
    new PreparedStatementCreator() {
        public PreparedStatement createPreparedStatement(Connection connection)
            throws SQLException {

            PreparedStatement statement = connection.prepareStatement(ourInsertQuery);
            //statement.setLong(1, beginning); set parameters you need in your insert

            return statement;
        }
    });

This is really weird, why nobody is mentioning the /IM switch ?! I've been using it for a long time in backup jobs. But I tried googling just now and I couldn't land on a single web page that says anything about it even on MS website !!! Also found so many user posts complaining about the same issue!!

Anyway.. to use Robocopy to overwrite EVERYTHING what ever size or time in source or distination you must include these three switches in your command (/IS /IT /IM)

/IS :: Include Same files. (Includes same size files)
/IT :: Include Tweaked files. (Includes same files with different Attributes)
/IM :: Include Modified files (Includes same files with different times).

This is the exact command I use to transfer few TeraBytes of mostly 1GB+ files (ISOs - Disk Images - 4K Videos):

robocopy B:\Source D:\Destination /E /J /COPYALL /MT:1 /DCOPY:DATE /IS /IT /IM /X /V /NP /LOG:A:\ROBOCOPY.LOG

I did a small test for you .. and here is the result:

               Total    Copied   Skipped  Mismatch    FAILED    Extras

Even with those "Extras", that's for reporting only because of the "/X" switch. As you can see nothing was Skipped and Total number and size of all files are equal to the Copied. Sometimes It will show small number of skipped files when I abuse it and cancel it multiple times during operation but even with that the values in the first 2 columns are always Equal. I also confirmed that once before by running a PowerShell script that scans all files in destination and generate a report of all time-stamps.

Some performance tips from my history with it and so many tests & troubles!:

. Despite of what most users online advise to use maximum threads "/MT:128" like it's a general trick to get the best performance ... PLEASE DON'T USE "/MT:128" WITH VERY LARGE FILES ... that's a big mistake and it will decrease your drive performance dramatically after several runs .. it will create very high fragmentation or even cause the files system to fail in some cases and you end up spending valuable time trying to recover a RAW partition and all that nonsense. And above all that, It will perform 4-6 times slower!!

For very large files:

1. Use Only "One" thread "/MT:1" | Impact: BIG
2. Must use "/J" to disable buffering. | Impact: High
3. Use "/NP" with "/LOG:file" and Don't output to the console by "/TEE" | Impact: Medium.
4. Put the "/LOG:file" on a separate drive from the source or destination | Impact: Low.

For regular big files:

1. Use multi threads, I would not exceed "/MT:4" | Impact: BIG
2. IF destination disk has low Cache specs use "/J" to disable buffering | Impact: High
3. & 4 same as above.

For thousands of tiny files:

1. Go nuts :) with Multi threads, at first I would start with 16 and multibly by 2 while monitoring the disk performance. Once it starts dropping I'll fall back to the prevouse value and stik with it | Impact: BIG
2. Don't use "/J" | Impact: High
3. Use "/NP" with "/LOG:file" and Don't output to the console by "/TEE" | Impact: HIGH.
4. Put the "/LOG:file" on a separate drive from the source or destination | Impact: HIGH.

maxAge = Persons.Max(c => c.age)

or something along those lines.

If you have the correct encoding in the string, you need not do more to get the bytes for another encoding.

public static void main(String[] args) throws Exception {
    printBytes("â");
    System.out.println(
            new String(new byte[] { (byte) 0xE2 }, "ISO-8859-1"));
    System.out.println(
            new String(new byte[] { (byte) 0xC3, (byte) 0xA2 }, "UTF-8"));
}

private static void printBytes(String str) {
    System.out.println("Bytes in " + str + " with ISO-8859-1");
    for (byte b : str.getBytes(StandardCharsets.ISO_8859_1)) {
        System.out.printf("%3X", b);
    }
    System.out.println();
    System.out.println("Bytes in " + str + " with UTF-8");
    for (byte b : str.getBytes(StandardCharsets.UTF_8)) {
        System.out.printf("%3X", b);
    }
    System.out.println();
}

Output:

Bytes in â with ISO-8859-1
 E2
Bytes in â with UTF-8
 C3 A2
â
â

You can now use the ZipArchive class (System.IO.Compression.ZipArchive), available from .NET 4.5

You have to add System.IO.Compression as a reference.

Example: Generating a zip of PDF files

using (var fileStream = new FileStream(@"C:\temp\temp.zip", FileMode.CreateNew))
{
    using (var archive = new ZipArchive(fileStream, ZipArchiveMode.Create, true))
    {
        foreach (var creditNumber in creditNumbers)
        {
            var pdfBytes = GeneratePdf(creditNumber);
            var fileName = "credit_" + creditNumber + ".pdf";
            var zipArchiveEntry = archive.CreateEntry(fileName, CompressionLevel.Fastest);
            using (var zipStream = zipArchiveEntry.Open())
                zipStream.Write(pdfBytes, 0, pdfBytes.Length);
            }
        }
    }
}

I use sym links all the time between my document root and git repo directory. I like to keep them separate. On windows I use mklink /j option. The junction seems to let git behave normally:

>mklink /j <location(path) of link> <source of link>

for example:

>mklink /j c:\gitRepos\Posts C:\Bitnami\wamp\apache2\htdocs\Posts

Do you have a "shared object" (usually a shared library on AIX), a UNIX shared library, or a Windows DLL? These are all different things, and your question conflates them all :-(

• For an AIX shared object, use dump -Tv /path/to/foo.o.
• For an ELF shared library, use readelf -Ws /path/to/libfoo.so, or (if you have GNU nm) nm -D /path/to/libfoo.so.
• For a non-ELF UNIX shared library, please state which UNIX you are interested in.
• For a Windows DLL, use dumpbin /EXPORTS foo.dll.

You can proceed as follow:

1. Install Charles Web Proxy.
2. Disable SSL proxying (uncheck the flag in Proxy->Proxy Settings...->SSL
3. Connect your iDevice to the Charles proxy, as explained here
4. Sniff the packets via Wireshark or Charles

My case it solved i was using

@Html.DropDownList(model => model.TypeId ...)  

using

@Html.DropDownListFor(model => model.TypeId ...) 

will solve it

A mix of native Javascript and jQuery:

var gFireEvent = function (oElem,sEvent) 
{
 try {
 if( typeof sEvent == 'string' && o.isDOM( oElem ))
 {
  var b = !!(document.createEvent),
     evt = b?document.createEvent("HTMLEvents"):document.createEventObject();
  if( b )    
  {  evt.initEvent(sEvent, true, true ); 
    return !oElem.dispatchEvent(evt);
  }
  return oElem.fireEvent('on'+sEvent,evt);
 }
 } catch(e) {}
 return false;
};


// Next you can do is (bIsMob etc you have to determine yourself):

   if( <<< bIsMob || bIsTab || bisTouch >>> )
   {
     $(document).on('mousedown', function(e)
     {
       gFireEvent(e.target,'mouseover' );
     }).on('mouseup', function(e)
     {
       gFireEvent(e.target,'mouseout' );
     });
   }

You need $event.currentTarget instead of $event.target.

Your question is a bit vague, but I suppose UPSERT could be considered a design pattern. For languages that don't implement MERGE, a number of alternatives to solve the problem (if a suitable rows exists, UPDATE; else INSERT) exist.

parseInt(Math.random().toString().slice(2,Math.min(length+2, 18)), 10); // 18 -> due to max digits in Math.random

Update: This method has few flaws: - Sometimes the number of digits might be lesser if its left padded with zeroes.

As far as find BlueBearr response the best (while I,m running my batch script with eg. SYSTEM rights) I have to add something to it. Because in my Windows language version (Polish) line that is to be catched by "%%a %%b"=="User Name:" gets REALLY COMPLICATED (it contains some diacritic characters in my language) I skip first 7 lines and operate on the 8th.

Previous answers got you list of torch.Size Here is how to get list of ints

listofints = [int(x) for x in tensor.shape]

Working around for few days into the same problem (and after check "playsinline" and "autoplay" and "muted" ok, "mime-types" and "range" in server ok, etc). The solution for all browsers was:

<video controls autoplay loop muted playsinline>
    <source src="https://example.com/my_video.mov" type="video/mp4">
</video>

Yes: convert video to .MOV and type="video/mp4" in the same tag. Working!

I'm sure there's some nice library that does this sort of thing already for you... But to just stick with the approach you're already going with, Map#entrySet gives you a combined Object with the key and the value. So something like:

for (Map.Entry<String, Object> entry : map.entrySet()) {
    System.out.println(entry.getKey() + ":" + entry.getValue().toString());
}

will do what you're after.

If you're using java 8, there's also the new streaming approach.

map.forEach((key, value) -> System.out.println(key + ":" + value));

You could simply use CSS animated text generator. There are pre-created templates already

I provide a more general and safer way to do this stuff,

".." <- function (x) 
{
  stopifnot(inherits(x, "character"))
  stopifnot(length(x) == 1)
  get(x, parent.frame(4))
}


set_colclass <- function(x, class){
  stopifnot(all(class %in% c("integer", "numeric", "double","factor","character")))
  for(i in intersect(names(class), names(x))){
    f <- get(paste0("as.", class[i]))
    x[, (..("i")):=..("f")(get(..("i")))]
  }
  invisible(x)
}

The function .. makes sure we get a variable out of the scope of data.table; set_colclass will set the classes of your cols. You can use it like this:

dt <- data.table(i=1:3,f=3:1)
set_colclass(dt, c(i="character"))
class(dt$i)

You have two options here.

1. Make a proper cron job that calls your script. Cron is a common name for a GNU/Linux daemon that periodically launches scripts according to a schedule you set. You add your script into a crontab or place a symlink to it into a special directory and the daemon handles the job of launching it in the background. You can read more at Wikipedia. There is a variety of different cron daemons, but your GNU/Linux system should have it already installed.

2. Use some kind of python approach (a library, for example) for your script to be able to daemonize itself. Yes, it will require a simple event loop (where your events are timer triggering, possibly, provided by sleep function).

I wouldn't recommend you to choose 2., because you would be, in fact, repeating cron functionality. The Linux system paradigm is to let multiple simple tools interact and solve your problems. Unless there are additional reasons why you should make a daemon (in addition to trigger periodically), choose the other approach.

Also, if you use daemonize with a loop and a crash happens, no one will check the mail after that (as pointed out by Ivan Nevostruev in comments to this answer). While if the script is added as a cron job, it will just trigger again.

If you installed tomcat7 using apt-get in linux then, deploy your app to /var/lib/tomcat7/webapps/

eg.

sudo service tomcat7 stop

mvn clean package
sudo cp target/DestroyTheWorldWithPeace.war /var/lib/tomcat7/webapps/
#you might also want to make sure war file has permission (`777` not just `+x`)
sudo service tomcat7 start

Also, keep tailing the tomcat log so that you can verify that your app is actually making peace with tomcat.

tail -f /var/lib/tomcat7/logs/catalina.out

The deployed application should appear in http://172.16.35.155:8080/manager/html

Think of the ? as to mean "unknown". Thus, "ArrayList<? extends Object>" is to say "an unknown type that (or as long as it)extends Object". Therefore, needful to say, arrayList.add(3) would be putting something you know, into an unknown. I.e 'Forgetting'.

Updated Answer In 2020

I was surprised that no other answers on this page mentioned git stash push.

This article helped me understand:

The command git stash is shorthand for git stash push. In this mode, non-option arguments are not allowed to prevent a misspelled subcommand from making an unwanted stash entry. There are also another alias for this command git stash save which is deprecated in favour of git stash push.

By default git ignores untracked files when doing stash. If those files need to be added to stash you can use -u options which tells git to include untracked files. Ignored files can be added as well if -a option is specified. -a will include both untracked and ignored files.

I care about naming my stashes, and I want them to include untracked files, so the command I most commonly run is: git stash push -u -m "whatIWantToNameThisStash"

I got same error everything was correct only i was using same statement interface object to execute and update the database. After separating i.e. using different objects of statement interface for updating and executing query i resolved this error. i.e. do get rid from this do not use same statement object for both updating and executing the query.

The default expiry_date for google oauth2 access token is 1 hour. The expiry_date is in the Unix epoch time in milliseconds. If you want to read this in human readable format then you can simply check it here..Unix timestamp to human readable time

My own humble (case sensitive) solution:

uint8_t strContains(char* string, char* toFind)
{
    uint8_t slen = strlen(string);
    uint8_t tFlen = strlen(toFind);
    uint8_t found = 0;

    if( slen >= tFlen )
    {
        for(uint8_t s=0, t=0; s<slen; s++)
        {
            do{

                if( string[s] == toFind[t] )
                {
                    if( ++found == tFlen ) return 1;
                    s++;
                    t++;
                }
                else { s -= found; found=0; t=0; }

              }while(found);
        }
        return 0;
    }
    else return -1;

You have to use @BotFather, send it command: /setjoingroups There will be dialog like this:

YOU: /setjoingroups

BotFather: Choose a bot to change group membership settings.

YOU: @YourBot

BotFather: 'Enable' - bot can be added to groups. 'Disable' - block group invitations, the bot can't be added to groups. Current status is: DISABLED

YOU: Enable

BotFather: Success! The new status is: ENABLED.

After this you will see button "Add to Group" in your bot's profile.

That's my version of a composite iterator that yields an index and any passed generator function's value with an example of (slow) prime search:

PHP provides two types of array.

• normal array
• SplFixedArray

normal array : This array is dynamic.

SplFixedArray : this is a standard php library which provides the ability to create array of fix size.

To improve on Johnny's answer, this can now be done using the public API as follows :

func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [UITableViewRowAction]? {

    let moreRowAction = UITableViewRowAction(style: UITableViewRowActionStyle.default, title: "More", handler:{action, indexpath in
        print("MORE•ACTION");
    });
    moreRowAction.backgroundColor = UIColor(red: 0.298, green: 0.851, blue: 0.3922, alpha: 1.0);

    let deleteRowAction = UITableViewRowAction(style: UITableViewRowActionStyle.default, title: "Delete", handler:{action, indexpath in
        print("DELETE•ACTION");
    });

    return [deleteRowAction, moreRowAction];
}

1. Install Msys2 http://www.msys2.org

Just added ignore: [] in the specific page for the specific form, this solution worked for me.

$("#form_name").validate({

        },      
        highlight:false,

When I use a non-default modules in my scripts I call the function below. Beside the module name you can provide a minimum version.

# See https://www.powershellgallery.com/ for module and version info
Function Install-ModuleIfNotInstalled(

    [string] $minimalVersion
) {
    $module = Get-Module -Name $moduleName -ListAvailable |`
        Where-Object { $null -eq $minimalVersion -or $minimalVersion -ge $_.Version } |`
        Select-Object -Last 1
    if ($null -ne $module) {
         Write-Verbose ('Module {0} (v{1}) is available.' -f $moduleName, $module.Version)
    }
    else {
        Import-Module -Name 'PowershellGet'
        $installedModule = Get-InstalledModule -Name $moduleName -ErrorAction SilentlyContinue
        if ($null -ne $installedModule) {
            Write-Verbose ('Module [{0}] (v {1}) is installed.' -f $moduleName, $installedModule.Version)
        }
        if ($null -eq $installedModule -or ($null -ne $minimalVersion -and $installedModule.Version -lt $minimalVersion)) {
            Write-Verbose ('Module {0} min.vers {1}: not installed; check if nuget v2.8.5.201 or later is installed.' -f $moduleName, $minimalVersion)
            #First check if package provider NuGet is installed. Incase an older version is installed the required version is installed explicitly
            if ((Get-PackageProvider -Name NuGet -Force).Version -lt '2.8.5.201') {
                Write-Warning ('Module {0} min.vers {1}: Install nuget!' -f $moduleName, $minimalVersion)
                Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Scope CurrentUser -Force
            }        
            $optionalArgs = New-Object -TypeName Hashtable
            if ($null -ne $minimalVersion) {
                $optionalArgs['RequiredVersion'] = $minimalVersion
            }  
            Write-Warning ('Install module {0} (version [{1}]) within scope of the current user.' -f $moduleName, $minimalVersion)
            Install-Module -Name $moduleName @optionalArgs -Scope CurrentUser -Force -Verbose
        } 
    }
}

usage example:

Install-ModuleIfNotInstalled 'CosmosDB' '2.1.3.528'

I have used time differences for continuous integration tests to check and improve my functions. Here is simple code if somebody need it

Use \t to add tab and \n for new line, here is a simple example below.

<string name="list_with_tab_tag">\tbanana\torange\tblueberry\tmango</string>
<string name="sentence_with_new_line_tag">This is the first sentence\nThis is the second scentence\nThis is the third sentence</string>

children() is a loop in itself.

$('.element').children().animate({
'opacity':'0'
});

Many good answers here already, although you also need to keep in mind that if you are doing long-running processing on the UI thread (generally a bad idea), then you won't see the marquee moving either.

for k, v in mydict.iteritems():
    if v is None:
        mydict[k] = ''

In a more general case, e.g. if you were adding or removing keys, it might not be safe to change the structure of the container you're looping on -- so using items to loop on an independent list copy thereof might be prudent -- but assigning a different value at a given existing index does not incur any problem, so, in Python 2.any, it's better to use iteritems.

In Python3 however the code gives AttributeError: 'dict' object has no attribute 'iteritems' error. Use items() instead of iteritems() here.

I think i am understanding your question. This filters things that are in the column labels or the row labels. The last 2 sections of the code is what you want but im pasting everything so that you can see exactly how It runs start to finish with everything thats defined etc. I definitely took some of this code from other sites fyi.

Near the end of the code, the "WardClinic_Category" is a column of my data and in the column label of the pivot table. Same for the IVUDDCIndicator (its a column in my data but in the row label of the pivot table).

Hope this helps others...i found it very difficult to find code that did this the "proper way" rather than using code similar to the macro recorder.

Expanding S.Lott's answer so that new items are processed as well:

todo = myarr
done = []
while todo:
    added = []
    for a in todo:
        if somecond(a):
            added.append(newObj())
    done.extend(todo)
    todo = added

The final list is in done.

Does Customer implement the equals() contract?

If it doesn't implement equals() and hashCode(), then listCustomer.contains(customer) will check to see if the exact same instance already exists in the list (By instance I mean the exact same object--memory address, etc). If what you are looking for is to test whether or not the same Customer( perhaps it's the same customer if they have the same customer name, or customer number) is in the list already, then you would need to override equals() to ensure that it checks whether or not the relevant fields(e.g. customer names) match.

Note: Don't forget to override hashCode() if you are going to override equals()! Otherwise, you might get trouble with your HashMaps and other data structures. For a good coverage of why this is and what pitfalls to avoid, consider having a look at Josh Bloch's Effective Java chapters on equals() and hashCode() (The link only contains iformation about why you must implement hashCode() when you implement equals(), but there is good coverage about how to override equals() too).

By the way, is there an ordering restriction on your set? If there isn't, a slightly easier way to solve this problem is use a Set<Customer> like so:

Set<Customer> noDups = new HashSet<Customer>();
noDups.addAll(tmpListCustomer);
return new ArrayList<Customer>(noDups);

Which will nicely remove duplicates for you, since Sets don't allow duplicates. However, this will lose any ordering that was applied to tmpListCustomer, since HashSet has no explicit ordering (You can get around that by using a TreeSet, but that's not exactly related to your question). This can simplify your code a little bit.

HTTP request POST in java does not dump the answer?

HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost(url);

// add header
post.setHeader("User-Agent", USER_AGENT);

List<NameValuePair> urlParameters = new ArrayList<>();
urlParameters.add(new BasicNameValuePair("accion", "busqueda"));
        urlParameters.add(new BasicNameValuePair("modo", "1"));
urlParameters.add(new BasicNameValuePair("nruc", "10469415177"));

post.setEntity(new UrlEncodedFormEntity(urlParameters));

HttpResponse response = client.execute(post);
System.out.println("\nSending 'POST' request to URL : " + url);
System.out.println("Post parameters : " + post.getEntity());
System.out.println("Response Code : " +response.getStatusLine().getStatusCode());

 InputStreamReader(response.getEntity().getContent()));

  StringBuilder result = new StringBuilder();
  String line = "";
  while ((line = rd.readLine()) != null)

First Option:

OPEN package.json and add "--port port-no" in "serve" section.

Just like below, I have done it.

{
  "name": "app-name",
  "version": "0.1.0",
  "private": true,
  "scripts": {
    "serve": "vue-cli-service serve --port 8090",
    "build": "vue-cli-service build",
    "lint": "vue-cli-service lint"
}

Second Option: If You want through command prompt

npm run serve --port 8090

For just reading the last element of a slice:

sl[len(sl)-1]

For removing it:

sl = sl[:len(sl)-1]

See this page about slice tricks

The answer is that you have to use TableRow.LayoutParams, not LinearLayout.LayoutParams or any other LayoutParams.

TextView tv = new TextView(v.getContext());
LayoutParams params = new TableRow.LayoutParams(0, LayoutParams.WRAP_CONTENT, 1f);
tv.setLayoutParams(params);

The different LayoutParams are not interchangeable and if you use the wrong one then nothing seems to happen. The text view's parent is a table row, hence:

Beginner

Introductory, no previous programming experience

• C++ Primer * (Stanley Lippman, Josée Lajoie, and Barbara E. Moo) (updated for C++11) Coming at 1k pages, this is a very thorough introduction into C++ that covers just about everything in the language in a very accessible format and in great detail. The fifth edition (released August 16, 2012) covers C++11. [Review]

  ^{* Not to be confused with C++ Primer Plus (Stephen Prata), with a significantly less favorable review.}

• Programming: Principles and Practice Using C++ (Bjarne Stroustrup, 2nd Edition - May 25, 2014) (updated for C++11/C++14) An introduction to programming using C++ by the creator of the language. A good read, that assumes no previous programming experience, but is not only for beginners.

Introductory, with previous programming experience

• A Tour of C++ (Bjarne Stroustrup) (2nd edition for C++17) The “tour” is a quick (about 180 pages and 14 chapters) tutorial overview of all of standard C++ (language and standard library, and using C++11) at a moderately high level for people who already know C++ or at least are experienced programmers. This book is an extended version of the material that constitutes Chapters 2-5 of The C++ Programming Language, 4th edition.

• Accelerated C++ (Andrew Koenig and Barbara Moo, 1st Edition - August 24, 2000) This basically covers the same ground as the C++ Primer, but does so on a fourth of its space. This is largely because it does not attempt to be an introduction to programming, but an introduction to C++ for people who've previously programmed in some other language. It has a steeper learning curve, but, for those who can cope with this, it is a very compact introduction to the language. (Historically, it broke new ground by being the first beginner's book to use a modern approach to teaching the language.) Despite this, the C++ it teaches is purely C++98. [Review]

Best practices

• Effective C++ (Scott Meyers, 3rd Edition - May 22, 2005) This was written with the aim of being the best second book C++ programmers should read, and it succeeded. Earlier editions were aimed at programmers coming from C, the third edition changes this and targets programmers coming from languages like Java. It presents ~50 easy-to-remember rules of thumb along with their rationale in a very accessible (and enjoyable) style. For C++11 and C++14 the examples and a few issues are outdated and Effective Modern C++ should be preferred. [Review]

• Effective Modern C++ (Scott Meyers) This is basically the new version of Effective C++, aimed at C++ programmers making the transition from C++03 to C++11 and C++14.

• Effective STL (Scott Meyers) This aims to do the same to the part of the standard library coming from the STL what Effective C++ did to the language as a whole: It presents rules of thumb along with their rationale. [Review]

Intermediate

• More Effective C++ (Scott Meyers) Even more rules of thumb than Effective C++. Not as important as the ones in the first book, but still good to know.

• Exceptional C++ (Herb Sutter) Presented as a set of puzzles, this has one of the best and thorough discussions of the proper resource management and exception safety in C++ through Resource Acquisition is Initialization (RAII) in addition to in-depth coverage of a variety of other topics including the pimpl idiom, name lookup, good class design, and the C++ memory model. [Review]

• More Exceptional C++ (Herb Sutter) Covers additional exception safety topics not covered in Exceptional C++, in addition to discussion of effective object-oriented programming in C++ and correct use of the STL. [Review]

• Exceptional C++ Style (Herb Sutter) Discusses generic programming, optimization, and resource management; this book also has an excellent exposition of how to write modular code in C++ by using non-member functions and the single responsibility principle. [Review]

• C++ Coding Standards (Herb Sutter and Andrei Alexandrescu) “Coding standards” here doesn't mean “how many spaces should I indent my code?” This book contains 101 best practices, idioms, and common pitfalls that can help you to write correct, understandable, and efficient C++ code. [Review]

• C++ Templates: The Complete Guide (David Vandevoorde and Nicolai M. Josuttis) This is the book about templates as they existed before C++11. It covers everything from the very basics to some of the most advanced template metaprogramming and explains every detail of how templates work (both conceptually and at how they are implemented) and discusses many common pitfalls. Has excellent summaries of the One Definition Rule (ODR) and overload resolution in the appendices. A second edition covering C++11, C++14 and C++17 has been already published. [Review]

• C++ 17 - The Complete Guide (Nicolai M. Josuttis) This book describes all the new features introduced in the C++17 Standard covering everything from the simple ones like 'Inline Variables', 'constexpr if' all the way up to 'Polymorphic Memory Resources' and 'New and Delete with overaligned Data'. [Review]

• C++ in Action (Bartosz Milewski). This book explains C++ and its features by building an application from ground up. [Review]

• Functional Programming in C++ (Ivan Cukic). This book introduces functional programming techniques to modern C++ (C++11 and later). A very nice read for those who want to apply functional programming paradigms to C++.

• Professional C++ (Marc Gregoire, 5th Edition - Feb 2021) Provides a comprehensive and detailed tour of the C++ language implementation replete with professional tips and concise but informative in-text examples, emphasizing C++20 features. Uses C++20 features, such as modules and std::format throughout all examples.

Advanced

• Modern C++ Design (Andrei Alexandrescu) A groundbreaking book on advanced generic programming techniques. Introduces policy-based design, type lists, and fundamental generic programming idioms then explains how many useful design patterns (including small object allocators, functors, factories, visitors, and multi-methods) can be implemented efficiently, modularly, and cleanly using generic programming. [Review]

• C++ Template Metaprogramming (David Abrahams and Aleksey Gurtovoy)

• C++ Concurrency In Action (Anthony Williams) A book covering C++11 concurrency support including the thread library, the atomics library, the C++ memory model, locks and mutexes, as well as issues of designing and debugging multithreaded applications. A second edition covering C++14 and C++17 has been already published. [Review]

• Advanced C++ Metaprogramming (Davide Di Gennaro) A pre-C++11 manual of TMP techniques, focused more on practice than theory. There are a ton of snippets in this book, some of which are made obsolete by type traits, but the techniques, are nonetheless useful to know. If you can put up with the quirky formatting/editing, it is easier to read than Alexandrescu, and arguably, more rewarding. For more experienced developers, there is a good chance that you may pick up something about a dark corner of C++ (a quirk) that usually only comes about through extensive experience.

Reference Style - All Levels

• The C++ Programming Language (Bjarne Stroustrup) (updated for C++11) The classic introduction to C++ by its creator. Written to parallel the classic K&R, this indeed reads very much like it and covers just about everything from the core language to the standard library, to programming paradigms to the language's philosophy. [Review] Note: All releases of the C++ standard are tracked in the question "Where do I find the current C or C++ standard documents?".

• C++ Standard Library Tutorial and Reference (Nicolai Josuttis) (updated for C++11) The introduction and reference for the C++ Standard Library. The second edition (released on April 9, 2012) covers C++11. [Review]

• The C++ IO Streams and Locales (Angelika Langer and Klaus Kreft) There's very little to say about this book except that, if you want to know anything about streams and locales, then this is the one place to find definitive answers. [Review]

C++11/14/17/… References:

• The C++11/14/17 Standard (INCITS/ISO/IEC 14882:2011/2014/2017) This, of course, is the final arbiter of all that is or isn't C++. Be aware, however, that it is intended purely as a reference for experienced users willing to devote considerable time and effort to its understanding. The C++17 standard is released in electronic form for 198 Swiss Francs.

• The C++17 standard is available, but seemingly not in an economical form – directly from the ISO it costs 198 Swiss Francs (about $200 US). For most people, the final draft before standardization is more than adequate (and free). Many will prefer an even newer draft, documenting new features that are likely to be included in C++20.

Even though the list of items is short, the quality is high.

• The C++ Core Guidelines (C++11/14/17/…) (edited by Bjarne Stroustrup and Herb Sutter) is an evolving online document consisting of a set of guidelines for using modern C++ well. The guidelines are focused on relatively higher-level issues, such as interfaces, resource management, memory management and concurrency affecting application architecture and library design. The project was announced at CppCon'15 by Bjarne Stroustrup and others and welcomes contributions from the community. Most guidelines are supplemented with a rationale and examples as well as discussions of possible tool support. Many rules are designed specifically to be automatically checkable by static analysis tools.

• cppreference.com (C++03/11/14/17/…) (initiated by Nate Kohl) is a wiki that summarizes the basic core-language features and has extensive documentation of the C++ standard library. The documentation is very precise but is easier to read than the official standard document and provides better navigation due to its wiki nature. The project documents all versions of the C++ standard and the site allows filtering the display for a specific version. The project was presented by Nate Kohl at CppCon'14.

• Ruminations on C++ - (Andrew Koenig and Barbara Moo) [Review]

• Advanced C++ Programming Styles and Idioms (James Coplien) A predecessor of the pattern movement, it describes many C++-specific “idioms”. It's certainly a very good book and might still be worth a read if you can spare the time, but quite old and not up-to-date with current C++.

• Large Scale C++ Software Design (John Lakos) Lakos explains techniques to manage very big C++ software projects. Certainly, a good read, if it only was up to date. It was written long before C++ 98 and misses on many features (e.g. namespaces) important for large-scale projects. If you need to work in a big C++ software project, you might want to read it, although you need to take more than a grain of salt with it. The first volume of a new edition is released in 2019.

• Inside the C++ Object Model (Stanley Lippman) If you want to know how virtual member functions are commonly implemented and how base objects are commonly laid out in memory in a multi-inheritance scenario, and how all this affects performance, this is where you will find thorough discussions of such topics.

• The Annotated C++ Reference Manual (Bjarne Stroustrup, Margaret A. Ellis) This book is quite outdated in the fact that it explores the 1989 C++ 2.0 version - Templates, exceptions, namespaces and new casts were not yet introduced. Saying that however, this book goes through the entire C++ standard of the time explaining the rationale, the possible implementations, and features of the language. This is not a book to learn programming principles and patterns on C++, but to understand every aspect of the C++ language.

• Thinking in C++ (Bruce Eckel, 2nd Edition, 2000). Two volumes; is a tutorial style free set of intro level books. Downloads: vol 1, vol 2. Unfortunately they're marred by a number of trivial errors (e.g. maintaining that temporaries are automatically const), with no official errata list. A partial 3^rd party errata list is available at http://www.computersciencelab.com/Eckel.htm, but it is apparently not maintained.

• Scientific and Engineering C++: An Introduction to Advanced Techniques and Examples (John Barton and Lee Nackman) It is a comprehensive and very detailed book that tried to explain and make use of all the features available in C++, in the context of numerical methods. It introduced at the time several new techniques, such as the Curiously Recurring Template Pattern (CRTP, also called Barton-Nackman trick). It pioneered several techniques such as dimensional analysis and automatic differentiation. It came with a lot of compilable and useful code, ranging from an expression parser to a Lapack wrapper. The code is still available online. Unfortunately, the books have become somewhat outdated in the style and C++ features, however, it was an incredible tour-de-force at the time (1994, pre-STL). The chapters on dynamics inheritance are a bit complicated to understand and not very useful. An updated version of this classic book that includes move semantics and the lessons learned from the STL would be very nice.

The title attribute works on most HTML tags and is widely supported by modern browsers.

For me, I have fixed the problem using android:layout_centerVertical="true" in a parent RelativeLayout:

<RelativeLayout ... >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:layout_centerVertical="true">

</RelativeLayout>

class Main {
    public static void main(String args[]) throws Exception {
        ApplicationContext ac = new
          ClassPathXmlApplicationContext("context.xml", Main.class);
        DataSource dataSource = (DataSource) ac.getBean("dataSource");
// DataSource mysqlDataSource = (DataSource) ac.getBean("mysqlDataSource");

        JdbcTemplate jdbcTemplate = new JdbcTemplate(dataSource);

        String prasobhName = 
        jdbcTemplate.query(
           "select first_name from customer where last_name like ?",
            new PreparedStatementSetter() {
              public void setValues(PreparedStatement preparedStatement) throws
                SQLException {
                  preparedStatement.setString(1, "nair%");
              }
            }, 
            new ResultSetExtractor<Long>() {
              public Long extractData(ResultSet resultSet) throws SQLException,
                DataAccessException {
                  if (resultSet.next()) {
                      return resultSet.getLong(1);
                  }
                  return null;
              }
            }
        );
        System.out.println(machaceksName);
    }
}

I wrote a simple library for manipulating the JavaScript date object. You can try this:

var dateString = timeSolver.getString(new Date(), "YYYY/MM/DD HH:MM:SS.SSS")

Library here: https://github.com/sean1093/timeSolver

you can print it in Rstudio with View() more convenient:

df %>% View()

View(df)

Considering React Function Components and using Hooks are getting more popular these days , I will give a simple example of how to Passing data from child to parent component

in Parent Function Component we will have :

import React, { useState, useEffect } from "react";

then

const [childData, setChildData] = useState("");

and passing setChildData (which do a job similar to this.setState in Class Components) to Child

return( <ChildComponent passChildData={setChildData} /> )

in Child Component first we get the receiving props

function ChildComponent(props){ return (...) }

then you can pass data anyhow like using a handler function

const functionHandler = (data) => {

props.passChildData(data);

}

You could use the third-party frozendict module to freeze your dict and make it hashable.

from frozendict import frozendict
my_dict = frozendict(my_dict)

For handling nested objects, you could go with:

import collections.abc

def make_hashable(x):
    if isinstance(x, collections.abc.Hashable):
        return x
    elif isinstance(x, collections.abc.Sequence):
        return tuple(make_hashable(xi) for xi in x)
    elif isinstance(x, collections.abc.Set):
        return frozenset(make_hashable(xi) for xi in x)
    elif isinstance(x, collections.abc.Mapping):
        return frozendict({k: make_hashable(v) for k, v in x.items()})
    else:
        raise TypeError("Don't know how to make {} objects hashable".format(type(x).__name__))

If you want to support more types, use functools.singledispatch (Python 3.7):

@functools.singledispatch
def make_hashable(x):
    raise TypeError("Don't know how to make {} objects hashable".format(type(x).__name__))

@make_hashable.register
def _(x: collections.abc.Hashable):
    return x

@make_hashable.register
def _(x: collections.abc.Sequence):
    return tuple(make_hashable(xi) for xi in x)

@make_hashable.register
def _(x: collections.abc.Set):
    return frozenset(make_hashable(xi) for xi in x)

@make_hashable.register
def _(x: collections.abc.Mapping):
    return frozendict({k: make_hashable(v) for k, v in x.items()})

# add your own types here

From Sql Server 2008 you have "date" format.

So you can use

SELECT * FROM LOGS WHERE CONVERT(date,[CHECK_IN]) BETWEEN '2013-10-18' AND '2013-10-18'

https://docs.microsoft.com/en-us/sql/t-sql/data-types/date-transact-sql

Install beautifulsoup4

Open cmd and type

pip install beautifulsoup4

I was looking for this same answer and I couldn't find anything that did exactly what I wanted so I created my own and posted it here:

http://seekieran.com/2011/03/jquery-scrolling-box/

Working Demo: http://jsbin.com/azoji3

Here is the important code:

function ScrollDown(){

  //var topVal = $('.up').parents(".container").find(".content").css("top").replace(/[^-\d\.]/g, '');
  var topVal = $(".content").css("top").replace(/[^-\d\.]/g, '');
    topVal = parseInt(topVal);
  console.log($(".content").height()+ " " + topVal);
  if(Math.abs(topVal) < ($(".content").height() - $(".container").height() + 60)){ //This is to limit the bottom of the scrolling - add extra to compensate for issues
  $('.up').parents(".container").find(".content").stop().animate({"top":topVal - 20  + 'px'},'slow');
    if (mouseisdown)
setTimeout(ScrollDown, 400);
  }

Recursion to make it happen:

 $('.dn').mousedown(function(event) {
    mouseisdown = true;
    ScrollDown();
}).mouseup(function(event) {
    mouseisdown = false;
});

Thanks to Jonathan Sampson for some code to start but it didn't work initially so I have heavily modified it. Any suggestions to improve it would be great here in either the comments or comments on the blog.

If you are working on localhost, create a separate APIkey for your development and then remove restrictions on that key so that your localhost can use it. Remember to not use this key on production, so you don't expose your key to hunters online.

I had the same issue and all attempts to get the restrictions working on my localhost environment was not successful until I created a separate apikey specifically for development and then removed its restrictions. However I don't use that key on production environment, and once am done with developments, I will delete the API key immediately.

I Know this post is late, but for people that will likely face this issue in the future, this is the best route to go.

If you want folding an all your editors, I found you can enable Folding in

Preferences > Editors > Structured Text Editors

Enable Folding

import matplotlib.pyplot as plt

You can also run once in your code

plt.gray()

This will show the images in grayscale as default

im = array(Image.open('I_am_batman.jpg').convert('L'))
plt.imshow(im)
plt.show()

    new java.util.Timer().schedule(new TimerTask(){
        @Override
        public void run() {
            System.out.println("Executed...");
           //your code here 
           //1000*5=5000 mlsec. i.e. 5 seconds. u can change accordngly 
        }
    },1000*5,1000*5); 

The short answer is that ol elements are not legally allowed inside p elements.

To see why, let's go to the spec! If you can get comfortable with the HTML spec, it will answer many of your questions and curiosities. You want to know if an ol can live inside a p. So…

4.5.1 The p element:

Categories: Flow content, Palpable content.
Content model: Phrasing content.

4.5.5 The ol element:

Categories: Flow content.
Content model: Zero or more li and script-supporting elements.

The first part says that p elements can only contain phrasing content (which are “inline” elements like span and strong).

The second part says ols are flow content (“block” elements like p and div). So they can't be used inside a p.

ols and other flow content can be used in in some other elements like div:

4.5.13 The div element:

Categories: Flow content, Palpable content.
Content model: Flow content.

You can simply add this line into your bootstrap_and_overides.css.less file

body { background: #000000 !important;}

that's it

I realise there is an accepted answer, but this may help people. I found I had a similar problem with a ASP.NET site using NET 3.5 framework when running it in Visual Studio 2012 using IIS Express 8. I'd tried all of the above solutions and none worked - in the end running the solution in the in-built VS 2012 webserver worked. Not sure why, but I suspect it was a link between 3.5 framework and IIS 8.

Check out this link about multi project setups.

Some things to point out, make sure you have your settings.gradle updated to reference both the app and library modules.

settings.gradle: include ':app', ':libraries:lib1', ':libraries:lib2'

Also make sure that the app's build.gradle has the followng:

dependencies {
     compile project(':libraries:lib1')
}

You should have the following structure:

 MyProject/
  | settings.gradle
  + app/
    | build.gradle
  + libraries/
    + lib1/
       | build.gradle
    + lib2/
       | build.gradle

The app's build.gradle should use the com.android.application plugin while any libraries' build.gradle should use the com.android.library plugin.

The Android Studio IDE should update if you're able to build from the command line with this setup.

Change your declarations to this:

double lateFee = 0.0;
double monthlyCharge = 0.0;
double annualRate = 0.0;

The error is caused because there is at least one path through your code where these variables end up not getting set to anything.

Use something like this -

SELECT DISTINCT COL_NAME FROM myTable WHERE UPPER(COL_NAME) LIKE UPPER('%PriceOrder%')

or

SELECT DISTINCT COL_NAME FROM myTable WHERE LOWER(COL_NAME) LIKE LOWER('%PriceOrder%')

You can enter a character and get Ascii Code Using this Code

For Example Enter a Character Like A You Get Ascii Code 65

function myFunction(){_x000D_
    var str=document.getElementById("id1");_x000D_
    if (str.value=="") {_x000D_
       str.focus();_x000D_
       return;_x000D_
    }_x000D_
    var a="ASCII Code is == >  ";_x000D_
document.getElementById("demo").innerHTML =a+str.value.charCodeAt(0);_x000D_
}

<p>Check ASCII code</p>_x000D_
_x000D_
<p>_x000D_
  Enter any character:  _x000D_
  <input type="text" id="id1" name="text1" maxLength="1"> </br>_x000D_
</p>_x000D_
_x000D_
<button onclick="myFunction()">Get ASCII code</button>_x000D_
_x000D_
<p id="demo" style="color:red;"></p>

This is for GridView.

 grid.Rows[0].Cells[1].ReadOnly = true;

Reflection, basically, i.e.

myObject.GetType().GetProperty(property).SetValue(myObject, "Bob", null);

or there are libraries to help both in terms of convenience and performance; for example with FastMember:

var wrapped = ObjectAccessor.Create(obj); 
wrapped[property] = "Bob";

(which also has the advantage of not needing to know in advance whether it is a field vs a property)

Here is another dirty hack :)

.application-title > img {
display: none;
}

.application-title::before {
content: url(path/example.jpg);
}

I was getting selectNode() param 1 is not of type node error.

changed the code to this and its working. (for chrome)

function copy_data(containerid) {_x000D_
  var range = document.createRange();_x000D_
  range.selectNode(containerid); //changed here_x000D_
  window.getSelection().removeAllRanges(); _x000D_
  window.getSelection().addRange(range); _x000D_
  document.execCommand("copy");_x000D_
  window.getSelection().removeAllRanges();_x000D_
  alert("data copied");_x000D_
}

<div id="select_txt">This will be copied to clipboard!</div>_x000D_
<button type="button" onclick="copy_data(select_txt)">copy</button>_x000D_
<br>_x000D_
<hr>_x000D_
<p>Try paste it here after copying</p>_x000D_
<textarea></textarea>

When page IsPostback, the following code work correctly. But when page first loading, there is not multiple newline in the textarea. Bug

textBox1.Text = "Line1\r\n\r\n\r\nLine2";

You have to make the UL inside the div behave like a block. Try adding

.navigation ul {
     display: inline-block;
}

I know this is stating the absolute obvious, but I feel it's worth adding this as an answer as it's the simplest of all:

const orderId = 1;
fetch('http://myapi.com/orders?order_id=' + orderId);

Question :

And if recursion is usually slower what is the technical reason for ever using it over for loop iteration?

Answer :

Because in some algorithms are hard to solve it iteratively. Try to solve depth-first search in both recursively and iteratively. You will get the idea that it is plain hard to solve DFS with iteration.

Another good thing to try out : Try to write Merge sort iteratively. It will take you quite some time.

Question :

Is it correct to say that everywhere recursion is used a for loop could be used?

Answer :

Yes. This thread has a very good answer for this.

Question :

And if it is always possible to convert an recursion into a for loop is there a rule of thumb way to do it?

Answer :

Trust me. Try to write your own version to solve depth-first search iteratively. You will notice that some problems are easier to solve it recursively.

Hint : Recursion is good when you are solving a problem that can be solved by divide and conquer technique.
