Programs & Examples On #Jquery tabs

If you need to get the tab index from outside the context of a tabs event, use this:

function getSelectedTabIndex() { 
    return $("#TabList").tabs('option', 'selected');
}

Update: From version 1.9 'selected' is changed to 'active'

$("#TabList").tabs('option', 'active')

This is an old question and most answers are a bit dated. Currently, I would do 1 of 2 things.

1. Create a program that takes the screenshots

I would use Pyppeteer to take screenshots of websites. This runs on the Puppeteer package. Puppeteer spins up a headless chrome browser, so the screenshots will look exactly like they would in a normal browser.

This is taken from the pyppeteer documentation:

import asyncio
from pyppeteer import launch

async def main():
    browser = await launch()
    page = await browser.newPage()
    await page.goto('https://example.com')
    await page.screenshot({'path': 'example.png'})
    await browser.close()

asyncio.get_event_loop().run_until_complete(main())

2. Use a screenshot API

You could also use a screenshot API such as this one. The nice thing is that you don't have to set everything up yourself but can simply call an API endpoint.

This is taken from the screenshot API's documentation:

import urllib.parse
import urllib.request
import ssl

ssl._create_default_https_context = ssl._create_unverified_context

# The parameters.
token = "YOUR_API_TOKEN"
url = urllib.parse.quote_plus("https://example.com")
width = 1920
height = 1080
output = "image"

# Create the query URL.
query = "https://screenshotapi.net/api/v1/screenshot"
query += "?token=%s&url=%s&width=%d&height=%d&output=%s" % (token, url, width, height, output)

# Call the API.
urllib.request.urlretrieve(query, "./example.png")

Amazingly I found actually all of these don't quite cover it, as they don't work for shorter format midnight of 0:0 and a few don't work for 00:00 either, I used and tested the following:

^([0-9]|0[0-9]|1?[0-9]|2[0-3]):[0-5]?[0-9]$

This is java answer.

df.select("id").collectAsList();

You have to take whole columns under resizebox. This code worked for me

\begin{table}[htbp]
\caption{Sample Table.}\label{tab1}
\resizebox{\columnwidth}{!}{\begin{tabular}{|l|l|l|l|l|}
\hline
URL &  First Time Visit & Last Time Visit & URL Counts & Value\\
\hline

Using the Select Tag helpers to render a SELECT element

In your GET action, create an object of your view model, load the EmployeeList collection property and send that to the view.

public IActionResult Create()
{
    var vm = new MyViewModel();
    vm.EmployeesList = new List<Employee>
    {
        new Employee { Id = 1, FullName = "Shyju" },
        new Employee { Id = 2, FullName = "Bryan" }
    };
    return View(vm);
}

And in your create view, create a new SelectList object from the EmployeeList property and pass that as value for the asp-items property.

@model MyViewModel
<form asp-controller="Home" asp-action="Create">

    <select asp-for="EmployeeId" 
            asp-items="@(new SelectList(Model.EmployeesList,"Id","FullName"))">
        <option>Please select one</option>
    </select>

    <input type="submit"/>

</form>

And your HttpPost action method to accept the submitted form data.

[HttpPost]
public IActionResult Create(MyViewModel model)
{
   //  check model.EmployeeId 
   //  to do : Save and redirect
}

Or

If your view model has a List<SelectListItem> as the property for your dropdown items.

public class MyViewModel
{
    public int EmployeeId { get; set; }
    public string Comments { get; set; }
    public List<SelectListItem> Employees { set; get; }
}

And in your get action,

public IActionResult Create()
{
    var vm = new MyViewModel();
    vm.Employees = new List<SelectListItem>
    {
        new SelectListItem {Text = "Shyju", Value = "1"},
        new SelectListItem {Text = "Sean", Value = "2"}
    };
    return View(vm);
}

And in the view, you can directly use the Employees property for the asp-items.

@model MyViewModel
<form asp-controller="Home" asp-action="Create">

    <label>Comments</label>
    <input type="text" asp-for="Comments"/>

    <label>Lucky Employee</label>
    <select asp-for="EmployeeId" asp-items="@Model.Employees" >
        <option>Please select one</option>
    </select>

    <input type="submit"/>

</form>

The class SelectListItem belongs to Microsoft.AspNet.Mvc.Rendering namespace.

Make sure you are using an explicit closing tag for the select element. If you use the self closing tag approach, the tag helper will render an empty SELECT element!

The below approach will not work

<select asp-for="EmployeeId" asp-items="@Model.Employees" />

But this will work.

<select asp-for="EmployeeId" asp-items="@Model.Employees"></select>

Getting data from your database table using entity framework

The above examples are using hard coded items for the options. So i thought i will add some sample code to get data using Entity framework as a lot of people use that.

Let's assume your DbContext object has a property called Employees, which is of type DbSet<Employee> where the Employee entity class has an Id and Name property like this

public class Employee
{
   public int Id { set; get; }
   public string Name { set; get; }
}

You can use a LINQ query to get the employees and use the Select method in your LINQ expression to create a list of SelectListItem objects for each employee.

public IActionResult Create()
{
    var vm = new MyViewModel();
    vm.Employees = context.Employees
                          .Select(a => new SelectListItem() {  
                              Value = a.Id.ToString(),
                              Text = a.Name
                          })
                          .ToList();
    return View(vm);
}

Assuming context is your db context object. The view code is same as above.

Using SelectList

Some people prefer to use SelectList class to hold the items needed to render the options.

public class MyViewModel
{
    public int EmployeeId { get; set; }
    public SelectList Employees { set; get; }
}

Now in your GET action, you can use the SelectList constructor to populate the Employees property of the view model. Make sure you are specifying the dataValueField and dataTextField parameters.

public IActionResult Create()
{
    var vm = new MyViewModel();
    vm.Employees = new SelectList(GetEmployees(),"Id","FirstName");
    return View(vm);
}
public IEnumerable<Employee> GetEmployees()
{
    // hard coded list for demo. 
    // You may replace with real data from database to create Employee objects
    return new List<Employee>
    {
        new Employee { Id = 1, FirstName = "Shyju" },
        new Employee { Id = 2, FirstName = "Bryan" }
    };
}

Here I am calling the GetEmployees method to get a list of Employee objects, each with an Id and FirstName property and I use those properties as DataValueField and DataTextField of the SelectList object we created. You can change the hardcoded list to a code which reads data from a database table.

The view code will be same.

<select asp-for="EmployeeId" asp-items="@Model.Employees" >
    <option>Please select one</option>
</select>

Render a SELECT element from a list of strings.

Sometimes you might want to render a select element from a list of strings. In that case, you can use the SelectList constructor which only takes IEnumerable<T>

var vm = new MyViewModel();
var items = new List<string> {"Monday", "Tuesday", "Wednesday"};
vm.Employees = new SelectList(items);
return View(vm);

The view code will be same.

Setting selected options

Some times,you might want to set one option as the default option in the SELECT element (For example, in an edit screen, you want to load the previously saved option value). To do that, you may simply set the EmployeeId property value to the value of the option you want to be selected.

public IActionResult Create()
{
    var vm = new MyViewModel();
    vm.Employees = new List<SelectListItem>
    {
        new SelectListItem {Text = "Shyju", Value = "11"},
        new SelectListItem {Text = "Tom", Value = "12"},
        new SelectListItem {Text = "Jerry", Value = "13"}
    };
    vm.EmployeeId = 12;  // Here you set the value
    return View(vm);
}

This will select the option Tom in the select element when the page is rendered.

Multi select dropdown

If you want to render a multi select dropdown, you can simply change your view model property which you use for asp-for attribute in your view to an array type.

public class MyViewModel
{
    public int[] EmployeeIds { get; set; }
    public List<SelectListItem> Employees { set; get; }
}

This will render the HTML markup for the select element with the multiple attribute which will allow the user to select multiple options.

@model MyViewModel
<select id="EmployeeIds" multiple="multiple" name="EmployeeIds">
    <option>Please select one</option>
    <option value="1">Shyju</option>
    <option value="2">Sean</option>
</select>

Setting selected options in multi select

Similar to single select, set the EmployeeIds property value to the an array of values you want.

public IActionResult Create()
{
    var vm = new MyViewModel();
    vm.Employees = new List<SelectListItem>
    {
        new SelectListItem {Text = "Shyju", Value = "11"},
        new SelectListItem {Text = "Tom", Value = "12"},
        new SelectListItem {Text = "Jerry", Value = "13"}
    };
    vm.EmployeeIds= new int[] { 12,13} ;  
    return View(vm);
}

This will select the option Tom and Jerry in the multi select element when the page is rendered.

Using ViewBag to transfer the list of items

If you do not prefer to keep a collection type property to pass the list of options to the view, you can use the dynamic ViewBag to do so.(This is not my personally recommended approach as viewbag is dynamic and your code is prone to uncatched typo errors)

public IActionResult Create()
{       
    ViewBag.Employees = new List<SelectListItem>
    {
        new SelectListItem {Text = "Shyju", Value = "1"},
        new SelectListItem {Text = "Sean", Value = "2"}
    };
    return View(new MyViewModel());
}

and in the view

<select asp-for="EmployeeId" asp-items="@ViewBag.Employees">
    <option>Please select one</option>
</select>

Using ViewBag to transfer the list of items and setting selected option

It is same as above. All you have to do is, set the property (for which you are binding the dropdown for) value to the value of the option you want to be selected.

public IActionResult Create()
{       
    ViewBag.Employees = new List<SelectListItem>
    {
        new SelectListItem {Text = "Shyju", Value = "1"},
        new SelectListItem {Text = "Bryan", Value = "2"},
        new SelectListItem {Text = "Sean", Value = "3"}
    };

    vm.EmployeeId = 2;  // This will set Bryan as selected

    return View(new MyViewModel());
}

and in the view

<select asp-for="EmployeeId" asp-items="@ViewBag.Employees">
    <option>Please select one</option>
</select>

Grouping items

The select tag helper method supports grouping options in a dropdown. All you have to do is, specify the Group property value of each SelectListItem in your action method.

public IActionResult Create()
{
    var vm = new MyViewModel();

    var group1 = new SelectListGroup { Name = "Dev Team" };
    var group2 = new SelectListGroup { Name = "QA Team" };

    var employeeList = new List<SelectListItem>()
    {
        new SelectListItem() { Value = "1", Text = "Shyju", Group = group1 },
        new SelectListItem() { Value = "2", Text = "Bryan", Group = group1 },
        new SelectListItem() { Value = "3", Text = "Kevin", Group = group2 },
        new SelectListItem() { Value = "4", Text = "Alex", Group = group2 }
    };
    vm.Employees = employeeList;
    return View(vm);
}

There is no change in the view code. the select tag helper will now render the options inside 2 optgroup items.

For me, this also worked:

def search(myDict, search1):
    search.a=[]
    for key, value in myDict.items():
        if search1 in value:
            search.a.append(key)

search(myDict, 'anyName')
print(search.a)

• search.a makes the list a globally available
• if a match of the substring is found in any value, the key of that value will be appended to a

Kind of, use the XmlAttribute instead of XmlElement, but it won't look like what you want. It will look like the following:

<SomeModel SomeStringElementName="testData"> 
</SomeModel> 

The only way I can think of to achieve what you want (natively) would be to have properties pointing to objects named SomeStringElementName and SomeInfoElementName where the class contained a single getter named "value". You could take this one step further and use DataContractSerializer so that the wrapper classes can be private. XmlSerializer won't read private properties.

// TODO: make the class generic so that an int or string can be used.
[Serializable]  
public class SerializationClass
{
    public SerializationClass(string value)
    {
        this.Value = value;
    }

    [XmlAttribute("value")]
    public string Value { get; }
}


[Serializable]                     
public class SomeModel                     
{                     
    [XmlIgnore]                     
    public string SomeString { get; set; }                     

    [XmlIgnore]                      
    public int SomeInfo { get; set; }  

    [XmlElement]
    public SerializationClass SomeStringElementName
    {
        get { return new SerializationClass(this.SomeString); }
    }               
}

1. If there is only one select tag in on the page then you can specify select inside of id 'list'

   jQuery("select option[value=2]").text();
   

2. To get selected text

   jQuery("select option:selected").text();
   

Accordig to this: https://bugs.mysql.com/bug.php?id=54784 casting as char should do the trick:

SELECT report_id, computer_id, MAX(CAST(date_entered AS CHAR))
FROM reports
GROUP BY report_id, computer_id

I ran into a similar problem where Visual Studio (2017) said it could not find my project's PDB file. I could see the PDB file did exist in the correct path. I had to Clean and Rebuild the project, then Visual Studio recognized the PDB file and debugging worked.

Simple Way To Achieve

I know it's an old question You can also do something like

SELECT * FROM Table WHERE id=1 ORDER BY signin DESC

In above, query the first record will be the most recent record.

For only one record you can use something like

SELECT top(1) * FROM Table WHERE id=1 ORDER BY signin DESC

Above query will only return one latest record.

Cheers!

First you have to open the file with open

input_file = open("nameOfFile.csv","r+")

Then use the csv.reader for open the csv

reader_file = csv.reader(input_file)

At the last, you can take the number of row with the instruction 'len'

value = len(list(reader_file))

The total code is this:

input_file = open("nameOfFile.csv","r+")
reader_file = csv.reader(input_file)
value = len(list(reader_file))

Remember that if you want to reuse the csv file, you have to make a input_file.fseek(0), because when you use a list for the reader_file, it reads all file, and the pointer in the file change its position

A better way to solve it is to start small.

Let's start with 1 bit. Which can either be 1 or 0. That's 2 values, or 10 in binary.

Now 2 bits, which can either be 00, 01, 10 or 11 That's 4 values, or 100 in binary... See the pattern?

As string is a list of characters, converting it to dictionary will remove all duplicates and will retain the order.

"".join(list(dict.fromkeys(foo)))

If you were resizing before uploading I just found out this http://www.plupload.com/

It does all the magic for you in any imaginable method.

Unfortunately HTML5 resize only is supported with Mozilla browser, but you can redirect other browsers to Flash and Silverlight.

I just tried it and it worked with my android!

I was using http://swfupload.org/ in flash, it does the job very well, but the resize size is very small. (cannot remember the limit) and does not go back to html4 when flash is not available.

The way you declare the date property as an input looks incorrect but its hard to say if it's the only problem without seeing all your code. Rather than using @Input('date') declare the date property like so: private _date: string;. Also, make sure you are instantiating the model with the new keyword. Lastly, access the property using regular dot notation.

Check your work against this example from https://www.typescriptlang.org/docs/handbook/classes.html :

let passcode = "secret passcode";

class Employee {
    private _fullName: string;

    get fullName(): string {
        return this._fullName;
    }

    set fullName(newName: string) {
        if (passcode && passcode == "secret passcode") {
            this._fullName = newName;
        }
        else {
            console.log("Error: Unauthorized update of employee!");
        }
    }
}

let employee = new Employee();
employee.fullName = "Bob Smith";
if (employee.fullName) {
    console.log(employee.fullName);
}

And here is a plunker demonstrating what it sounds like you're trying to do: https://plnkr.co/edit/OUoD5J1lfO6bIeME9N0F?p=preview

Inner join matches tables on keys, but outer join matches keys just for one side. For example when you use left outer join the query brings the whole left side table and matches the right side to the left table primary key and where there is not matched places null.

my two cents on this function:

var result = [];
for (var len = array.length, i = 0; i < len; ++i) {
  var age = array[i].age;
  if (result.indexOf(age) > -1) continue;
  result.push(age);
}

You can see the result here (Method 8) http://jsperf.com/distinct-values-from-array/3

Interestingly putting <httpCookies httpOnlyCookies="false"/> doesn't seem to disable httpOnlyCookies in ASP.NET 2.0. Check this article about SessionID and Login Problems With ASP .NET 2.0.

Looks like Microsoft took the decision to not allow you to disable it from the web.config. Check this post on forums.asp.net

If the list of acceptable characters is pretty small, you can use a regular expression like this:

Regex.IsMatch(items, "[a-z0-9 ]+", RegexOptions.IgnoreCase);

The regular expression used here looks for any character from a-z and 0-9 including a space (what's inside the square brackets []), that there is one or more of these characters (the + sign--you can use a * for 0 or more). The final option tells the regex parser to ignore case.

This will fail on anything that is not a letter, number, or space. To add more characters to the blessed list, add it inside the square brackets.

I would like to echo Jason's response though sometimes you need to naively parse some Html and pull out the text content.

I needed to do this with some Html which had been created by a rich text editor, always fun and games.

In this case you may need to remove the content of some tags as well as just the tags themselves.

In my case and tags were thrown into this mix. Some one may find my (very slightly) less naive implementation a useful starting point.

   /// <summary>
    /// Removes all html tags from string and leaves only plain text
    /// Removes content of <xml></xml> and <style></style> tags as aim to get text content not markup /meta data.
    /// </summary>
    /// <param name="input"></param>
    /// <returns></returns>
    public static string HtmlStrip(this string input)
    {
        input = Regex.Replace(input, "<style>(.|\n)*?</style>",string.Empty);
        input = Regex.Replace(input, @"<xml>(.|\n)*?</xml>", string.Empty); // remove all <xml></xml> tags and anything inbetween.  
        return Regex.Replace(input, @"<(.|\n)*?>", string.Empty); // remove any tags but not there content "<p>bob<span> johnson</span></p>" becomes "bob johnson"
    }

Have you seen this one? From http://www.aspspider.com/resources/Resource510.aspx:

        row[4] = Convert.ToString(((Microsoft.Office.Interop.Excel.Range)workSheet.Cells[rowIndex, 5]).Value2);
        index++;

        rowIndex = 2 + index;

I think the best that's possible in cross-browser JavaScript is window.print(), which (in Firefox 3, for me) brings up the 'print' dialog and not the print preview dialog.

FYI, the print dialog is your computer's Print popup, what you get when you do Ctrl-p. The print preview is Firefox's own Preview window, and it has more options. It's what you get with Firefox Menu > Print...

We can use this method to save using API. LearnersModules is the module file on our Angular files SaveSampleExams is the service file is one function method.

numpy 1D array --> column/row matrix:

>>> a=np.array([1,2,4])
>>> a[:, None]    # col
array([[1],
       [2],
       [4]])
>>> a[None, :]    # row, or faster `a[None]`
array([[1, 2, 4]])

And as @joe-kington said, you can replace None with np.newaxis for readability.

This simple function recursively merges JSON objects, please notice that this function merges all JSON into first param (target), if you need new object modify this code.

var mergeJSON = function (target, add) {
    function isObject(obj) {
        if (typeof obj == "object") {
            for (var key in obj) {
                if (obj.hasOwnProperty(key)) {
                    return true; // search for first object prop
                }
            }
        }
        return false;
    }
    for (var key in add) {
        if (add.hasOwnProperty(key)) {
            if (target[key] && isObject(target[key]) && isObject(add[key])) {
                this.mergeJSON(target[key], add[key]);
            } else {
                target[key] = add[key];
            }
        }
    }
    return target;
};

BTW instead of isObject() function may be used condition like this:

JSON.stringify(add[key])[0] == "{"

but this is not good solution, because it's will take a lot of resources if we have large JSON objects.

If your current min. API level is 23, you can simply use getColor() like we are using to get string resources by getString():

//example
textView.setTextColor(getColor(R.color.green));
// if `Context` is not available, use with context.getColor()

You can constraint for API Levels below 23:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    textView.setTextColor(getColor(R.color.green));
} else {
    textView.setTextColor(getResources().getColor(R.color.green));
}

but to keep it simple, you can do like below as accepted answer:

textView.setTextColor(ContextCompat.getColor(context, R.color.green))

From Resources.

From ContextCompat AndroidX.

From ContextCompat Support

it can also be achieved with below code

import re

text = 'how are u? umberella u! u. U. U@ U# u '
print (re.sub (r'[uU] ( [^a-z] )', r' you\1 ', text))

or

print (re.sub (r'[uU] ( [\s!,.?@#] )', r' you\1 ', text))

I am using Laravel 5.4 and response()->file('path/to/file.ext') to open e.g. a pdf in inline-mode in browsers. This works quite well, but when a user wants to save the file, the save-dialog suggests the last part of the url as filename.

I already tried adding a headers-array like mentioned in the Laravel-docs, but this doesn't seem to override the header set by the file()-method:

return response()->file('path/to/file.ext', [
  'Content-Disposition' => 'inline; filename="'. $fileNameFromDb .'"'
]);

Another gotcha here wasted some of my time, so I thought I would pass along the tip. I had a hidden field I gave an id that had . and [] brackets in the name (due to use with struts2) and the selector $("#model.thefield[0]") would not find my hidden field. Renaming the id to not use the periods and brackets caused the selector to begin working. So in the end I ended up with an id of model_the_field_0 instead and the selector worked fine.

These questions come up all the time due to JavaScript's typing system. People think they are getting a number when they're getting the string of a number.

Here are some things you might see that take advantage of the way JavaScript deals with strings and numbers. Personally, I wish JavaScript had used some symbol other than + for string concatenation.

Step (1) Concatenate "1", "2", "3" into "123"

result = "1" + "2" + "3";

Step (2) Convert "123" into 123

result = +"123";

Step (3) Add 123 + 100 = 223

result = 123 + 100;

Step (4) Convert 223 into "223"

result = "" + 223;

If you know WHY these work, you're less likely to get into trouble with JavaScript expressions.

One of the most possible causes of this error could be that you have defined older version in your package.json. To solve this problem, change the versions in the package.json to match those npm is complaining about.

Once done, run npm install and voila!!.

You say you've had problems with Navicat. For the record, I use Navicat and I haven't experienced the issue you describe. You might want to dig around, see if there's a reason for your problem and/or a solution, because given the question asked, my first recommendation would have been Navicat.

But if you want alternative suggestions, here are a few that I know of and have used:

MySQL has its own tool which you can download for free, called MySQL Workbench. Download it from here: http://wb.mysql.com/. My experience is that it's powerful, but I didn't really like the UI. But that's just my personal taste.

Another free program you might want to try is HeidiSQL. It's more similar to Navicat than MySQL Workbench. A colleague of mine loves it.

(interesting to note, by the way, that MariaDB (the forked version of MySQL) is currently shipped with HeidiSQL as its GUI tool)

Finally, if you're running a web server on your machine, there's always the option of a browser-based tool like PHPMyAdmin. It's actually a surprisingly powerful piece of software.

Here's a solution for Bootstrap4. You just need to put the card-header class in the a tag. This is a modified from an example in W3Schools.

This should work:

#!/bin/bash

if [ "$#" -eq 0 ] || [ "$#" -gt 1 ] ; then
    echo "hello"
fi

I'm not sure if this is different in other shells but if you wish to use <, >, you need to put them inside double parenthesis like so:

if (("$#" > 1))
 ...

This works fine for 2 tables. I have 3 tables and on clause has to link 2 conditions from 3 tables. My code:

from p in _dbContext.Products join pv in _dbContext.ProductVariants on p.ProduktId equals pv.ProduktId join jpr in leftJoinQuery on new { VariantId = pv.Vid, ProductId = p.ProduktId } equals new { VariantId = jpr.Prices.VariantID, ProductId = jpr.Prices.ProduktID } into lj

But its showing error at this point: join pv in _dbContext.ProductVariants on p.ProduktId equals pv.ProduktId

Error: The type of one of the expressions in the join clause is incorrect. Type inference failed in the call to 'GroupJoin'.

spans not have the value in html

one is the id for span tag

in javascript use

document.getElementById('one').innerText;

in jQuery use

$('#one').text()

function check() {
    var content = document.getElementById("one").innerText;
    alert(content);
}

or

function check() {
        var content = $('#one').text();
        alert(content);
    }

Just use this: ExtractFilePath(your_path_file_name)

If you want to return some value then wrap your statement in function

function my_function(){ 

 return my_thing; 
}

Problem is with the statement on the 1st line if you are trying to use PHP

var ask = confirm ('".$message."'); 

IF you are trying to use PHP you should use

 var ask = confirm (<?php echo "'".$message."'" ?>); //now message with be the javascript string!!

Seems like you can't iterate through JSONArray with a for each. You can loop through your JSONArray like this:

for (int i=0; i < arr.length(); i++) {
    arr.getJSONObject(i);
}

URLs are not resolved based on the file structure in the server side. URLs are resolved based on the real public web addresses of the resources in question. It's namely the webbrowser who has got to invoke them, not the webserver.

There are several ways to soften the pain:

JSF EL offers a shorthand to ${pageContext.request} in flavor of #{request}:

<li><a href="#{request.contextPath}/index.xhtml">Home</a></li>
<li><a href="#{request.contextPath}/about_us.xhtml">About us</a></li>

You can if necessary use <c:set> tag to make it yet shorter. Put it somewhere in the master template, it'll be available to all pages:

<c:set var="root" value="#{request.contextPath}/" />
...
<li><a href="#{root}index.xhtml">Home</a></li>
<li><a href="#{root}about_us.xhtml">About us</a></li>

JSF 2.x offers the <h:link> which can take a view ID relative to the context root in outcome and it will append the context path and FacesServlet mapping automatically:

<li><h:link value="Home" outcome="index" /></li>
<li><h:link value="About us" outcome="about_us" /></li>

HTML offers the <base> tag which makes all relative URLs in the document relative to this base. You could make use of it. Put it in the <h:head>.

<base href="#{request.requestURL.substring(0, request.requestURL.length() - request.requestURI.length())}#{request.contextPath}/" />
...
<li><a href="index.xhtml">Home</a></li>
<li><a href="about_us.xhtml">About us</a></li>

(note: this requires EL 2.2, otherwise you'd better use JSTL fn:substring(), see also this answer)

This should end up in the generated HTML something like as

<base href="http://example.com/webname/" />

Note that the <base> tag has a caveat: it makes all jump anchors in the page like <a href="#top"> relative to it as well! See also Is it recommended to use the <base> html tag? In JSF you could solve it like <a href="#{request.requestURI}#top">top</a> or <h:link value="top" fragment="top" />.

import os

os.system("python myOtherScript.py arg1 arg2 arg3")  

Using os you can make calls directly to your terminal. If you want to be even more specific you can concatenate your input string with local variables, ie.

command = 'python myOtherScript.py ' + sys.argv[1] + ' ' + sys.argv[2]
os.system(command)

I tried using the solution By @davy-c but had an Exception "System.FormatException: 'Input string was not in a correct format.'", this was due to there still being text past the line number, I modified the code he posted and came up with:

int line = Convert.ToInt32(objErr.ToString().Substring(objErr.ToString().IndexOf("line")).Substring(0, objErr.ToString().Substring(objErr.ToString().IndexOf("line")).ToString().IndexOf("\r\n")).Replace("line ", ""));

This works for me in VS2017 C#.

Try this:

v=spf1 ip4:abc.de.fgh.ij ip4:klm.no.pqr.st ~all

We are using VirtualBox as a provider and for the virtual box, you can use VBoxManage to get the IP address

VBoxManage guestproperty get <virtual-box-machine-name> /VirtualBox/GuestInfo/Net/1/V4/IP

It has to do with the order in which bytes are stored in memory. The decimal number 5001 is 0x1389 in hexadecimal, so the bytes involved are 0x13 and 0x89. Many devices store numbers in little-endian format, meaning that the least significant byte comes first. So in this particular example it means that in memory the number 5001 will be stored as

0x89 0x13

The htons() function makes sure that numbers are stored in memory in network byte order, which is with the most significant byte first. It will therefore swap the bytes making up the number so that in memory the bytes will be stored in the order

0x13 0x89

On a little-endian machine, the number with the swapped bytes is 0x8913 in hexadecimal, which is 35091 in decimal notation. Note that if you were working on a big-endian machine, the htons() function would not need to do any swapping since the number would already be stored in the right way in memory.

The underlying reason for all this swapping has to do with the network protocols in use, which require the transmitted packets to use network byte order.

I was able to read request body in an asp.net core 3.1 application like this (together with a simple middleware that enables buffering -enable rewinding seems to be working for earlier .Net Core versions-) :

var reader = await Request.BodyReader.ReadAsync();
Request.Body.Position = 0;
var buffer = reader.Buffer;
var body = Encoding.UTF8.GetString(buffer.FirstSpan);
Request.Body.Position = 0;

You are using the FTP in an active mode.

Setting up the FTP in the active mode can be cumbersome nowadays due to firewalls and NATs.

It's likely because of your local firewall or NAT that the server was not able to connect back to your client to establish data transfer connection.

Or your client is not aware of its external IP address and provides an internal address instead to the server (in PORT command), which the server is obviously not able to use. But it should not be the case, as vsftpd by default rejects data transfer address not identical to source address of FTP control connection (the port_promiscuous directive).

See my article Network Configuration for Active Mode.

If possible, you should use a passive mode as it typically requires no additional setup on a client-side. That's also what the server suggested you by "Consider using PASV". The PASV is an FTP command used to enter the passive mode.

Unfortunately Windows FTP command-line client (the ftp.exe) does not support passive mode at all. It makes it pretty useless nowadays.

Use any other 3rd party Windows FTP command-line client instead. Most other support the passive mode.

For example WinSCP FTP client defaults to the passive mode and there's a guide available for converting Windows FTP script to WinSCP script.

(I'm the author of WinSCP)

If you are using Minikube, there is a magic command!

$ minikube tunnel

Hopefully someone can save a few minutes with this.

Reference link https://minikube.sigs.k8s.io/docs/handbook/accessing/#using-minikube-tunnel

The POST/GET with 204 seems fine in the first sight and will also work.

Documentation says, 2xx -- This class of status codes indicates the action requested by the client was received, understood, accepted, and processed successfully. whereas 4xx -- The 4xx class of status code is intended for situations in which the client seems to have erred.

Since, the request was successfully received, understood and processed on server. The result was that the resource was not found. So, in this case this was not an error on the client side or the client has not erred.

Hence this should be a series 2xx code and not 4xx. Sending 204 (No Content) in this case will be better than a 404 or 410 response.

You can use XmlDocument. Also some XPath can be useful.

Just a simple example

XmlDocument doc = new XmlDocument();
doc.Load("sample.xml");
XmlElement root = doc.DocumentElement;
XmlNodeList nodes = root.SelectNodes("some_node"); // You can also use XPath here
foreach (XmlNode node in nodes)
{
   // use node variable here for your beeds
}

UPDATE for Bootstrap 4 stable

The cursor: pointer; rule has been restored, so buttons will now by default have the cursor on hover:

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css">_x000D_
<button type="button" class="btn btn-success">Sample Button</button>

No, there isn't. You need to make some custom CSS for this.

If you just need a link that looks like a button (with pointer), use this:

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.2/css/bootstrap.min.css">_x000D_
<a class="btn btn-success" href="#" role="button">Sample Button</a>

For UTF8 encoded JSON file using .NET Core 3.1, I was finally able to use JsonDocument based upon this information from Microsoft: https://docs.microsoft.com/en-us/dotnet/standard/serialization/system-text-json-how-to#utf8jsonreader-utf8jsonwriter-and-jsondocument

string allLinesAsOneString = string.Empty;
string [] lines = File.ReadAllLines(filename, Encoding.UTF8);
foreach(var line in lines)
    allLinesAsOneString += line;

JsonDocument jd = JsonDocument.Parse(Encoding.UTF8.GetBytes(allLinesAsOneString));
var writer = new Utf8JsonWriter(Console.OpenStandardOutput(), new JsonWriterOptions
{
    Indented = true
});
JsonElement root = jd.RootElement;
if( root.ValueKind == JsonValueKind.Object )
{
    writer.WriteStartObject();
}
foreach (var jp in root.EnumerateObject())
    jp.WriteTo(writer);
writer.WriteEndObject();

writer.Flush();

You can use the form attribute id to span a form over multiple elements each using the form attribute with the name of the form as follows:

<table>
     <tr>
          <td>
               <form method="POST" id="form-1" action="/submit/form-1"></form>
               <input name="a" form="form-1">
          </td>
          <td><input name="b" form="form-1"></td>
          <td><input name="c" form="form-1"></td>
          <td><input type="submit" form="form-1"></td>
     </tr>
</table>

Just as there are printer drivers that do not connect to a printer at all but rather write to a PDF file, analogously there are virtual audio drivers available that do not connect to a physical microphone at all but can pipe input from other sources such as files or other programs.

I hope I'm not breaking any rules by recommending free/donation software, but VB-Audio Virtual Cable should let you create a pair of virtual input and output audio devices. Then you could play an MP3 into the virtual output device and then set the virtual input device as your "microphone". In theory I think that should work.

If all else fails, you could always roll your own virtual audio driver. Microsoft provides some sample code but unfortunately it is not applicable to the older Windows XP audio model. There is probably sample code available for XP too.

.NET core now has EF.Functions.Like

  var isMatch = EF.Functions.Like(stringThatMightMatch, pattern);

Here are some simple mappings that can be used to quote and unquote a word:

" 'quote' a word
nnoremap qw :silent! normal mpea'<Esc>bi'<Esc>`pl
" double "quote" a word
nnoremap qd :silent! normal mpea"<Esc>bi"<Esc>`pl
" remove quotes from a word
nnoremap wq :silent! normal mpeld bhd `ph<CR>

We wrote a CLI tool for this purpose: docker-ls It allows you to browse a docker registry and supports authentication via token or basic auth.

You can use the RedirectToAction() method, then the action you redirect to can return a View. The easiest way to do this is:

return RedirectToAction("Index", model);

Then in your Index method, return the view you want.

Check the type property. Would that suffice?

Your range value is incorrect. You are referencing cell "75" which does not exist. You might want to use the R1C1 notation to use numeric columns easily without needing to convert to letters.

http://www.bettersolutions.com/excel/EED883/YI416010881.htm

Range("R" & DataImportRow & "C" & DataImportColumn).Offset(0, 2).Value = iFirstCustomerSales

This should fix your problem.

Pure js approach:

var elem = document.getElementsByClassName('parent');
alert(elem[0].hasAttribute('id'));

JsFiddle Demo

Detecting the HTTP method or so called REQUEST METHOD can be done using the following code snippet.

$method = $_SERVER['REQUEST_METHOD'];
if ($method == 'POST'){
    // Method is POST
} elseif ($method == 'GET'){
    // Method is GET
} elseif ($method == 'PUT'){
    // Method is PUT
} elseif ($method == 'DELETE'){
    // Method is DELETE
} else {
    // Method unknown
}

You could also do it using a switch if you prefer this over the if-else statement.

If a method other than GET or POST is required in an HTML form, this is often solved using a hidden field in the form.

<!-- DELETE method -->
<form action='' method='POST'>
    <input type="hidden" name'_METHOD' value="DELETE">
</form>

<!-- PUT method -->
<form action='' method='POST'>
    <input type="hidden" name'_METHOD' value="PUT">
</form>

For more information regarding HTTP methods I would like to refer to the following StackOverflow question:

HTTP protocol's PUT and DELETE and their usage in PHP

You could try using MultiMap instead of HashMap

Initialising it will require fewer lines of codes. Adding and retrieving the values will also make it shorter.

Map<String, List<Integer>> map = new HashMap<String, List<Integer>>();

would become:

Multimap<String, Integer> multiMap = ArrayListMultimap.create();

You can check this link: http://java.dzone.com/articles/hashmap-%E2%80%93-single-key-and

You can use the following function to return only the correlation coefficient:

def pearson_r(x, y):
"""Compute Pearson correlation coefficient between two arrays."""

   # Compute correlation matrix
   corr_mat = np.corrcoef(x, y)

   # Return entry [0,1]
   return corr_mat[0,1]

You can use a custom serializer at your money field. Here's an example with a MoneyBean. The field amount gets annotated with @JsonSerialize(using=...).

public class MoneyBean {
    //...

    @JsonProperty("amountOfMoney")
    @JsonSerialize(using = MoneySerializer.class)
    private BigDecimal amount;

    //getters/setters...
}

public class MoneySerializer extends JsonSerializer<BigDecimal> {
    @Override
    public void serialize(BigDecimal value, JsonGenerator jgen, SerializerProvider provider) throws IOException,
            JsonProcessingException {
        // put your desired money style here
        jgen.writeString(value.setScale(2, BigDecimal.ROUND_HALF_UP).toString());
    }
}

That's it. A BigDecimal is now printed in the right way. I used a simple testcase to show it:

@Test
public void jsonSerializationTest() throws Exception {
     MoneyBean m = new MoneyBean();
     m.setAmount(new BigDecimal("20.3"));

     ObjectMapper mapper = new ObjectMapper();
     assertEquals("{\"amountOfMoney\":\"20.30\"}", mapper.writeValueAsString(m));
}

I think that the idea of setting the Auto Return values as described above by Kevin is a bit strange!

Say, for example, that you have a number of websites that use the same PayPal account to handle your payments, or say that you have a number of sections in one website that perform different purchasing tasks, and require different return-addresses when the payment is completed. If I put a button on my page as described above in the 'Sample form using PHP for direct payments' section, you can see that there is a line there:

input type="hidden" name="return" value="https://www.yoursite.com/checkout_complete.php"

where you set the individual return value. Why does it have to be set generally, in the profile section as well?!?!

Also, because you can only set one value in the Profile Section, it means (AFAIK) that you cannot use the Auto Return on a site with multiple actions.

Comments please??

You can easily make SSH connections using SSHLibrary. Read this post :

https://workpython.blogspot.com/2020/04/creating-ssh-connections-with-python.html

This could also occur if you refer to a variable in the data.frame that doesn't exist. For example, recently I forgot to tell ddply to summarize by one of my variables that I used in geom_line to specify line color. Then, ggplot didn't know where to find the variable I hadn't created in the summary table, and I got this error.

In, Swift 3.0 you have set date object for this way.

extension Date
{
    init(dateString:String) {
        let dateStringFormatter = DateFormatter()
        dateStringFormatter.dateFormat = "yyyy-MM-dd"
        dateStringFormatter.locale = Locale(identifier: "en_US_POSIX")
        let d = dateStringFormatter.date(from: dateString)!
        self(timeInterval:0, since:d)
    }
}

Had this problem a number of times on our setup, so I've made a check list.

This assumes you want phpMyAdmin connecting locally to MySQL using a UNIX socket rather than TCP/IP.

UNIX sockets should be slightly faster as they have less overhead and can be more secure as they can only be accessed locally.

Service

• Is the mysqld service running? service mysqld status
• .. If not service mysqld start
• Has config has changed since service started? service mysqld restart

MySQL Config (my.cnf)

• Check that there isn't a non-socket client protocol set, e.g. protocol=tcp
• Check that the socket location is accessible and has the right permissions

PHP Config (php.ini)

If you can connect locally from the command line, but not from phpMyAdmin, and the socket file is not in the default location:

• Set the mysqli default sockets to the new location: mysqli.default_socket = *location*
• ... I also set the pdo_myql.default_socket and mysql.default_socket just to be sure
• Restart your web service (httpd in my case) service httpd restart

phpMyAdmin Config (config.inc.php)

• Check that the host is set to localhost: $cfg['Servers'][$i]['host'] = 'localhost';
• The socket location can also be set here: $cfg['Servers'][$i]['socket'] = '*location*';

N.B.

As pointed out by @chk; Setting the $cfg['Servers'][$i]['host'] from localhost to 127.0.0.1 just causes the connection to use TCP/IP rather than using the socket and is more of a workaround than a solution.

The MySQL config setting bind-address= also only affects TCP/IP connections.

If you don't need remote connections, it is recommended to turn off TCP/IP listening with skip-networking.

Edit: Whoops, didn't check your question tags before answering.

Check that you can actually connect to DB (have the driver placed? tested the conn when creating it?).

If so, try runnung those queries with F5

At the time of writing this is the most recent version of objc.h:

/// Type to represent a boolean value.
#if (TARGET_OS_IPHONE && __LP64__)  ||  TARGET_OS_WATCH
#define OBJC_BOOL_IS_BOOL 1
typedef bool BOOL;
#else
#define OBJC_BOOL_IS_CHAR 1
typedef signed char BOOL; 
// BOOL is explicitly signed so @encode(BOOL) == "c" rather than "C" 
// even if -funsigned-char is used.
#endif

It means that on 64-bit iOS devices and on WatchOS BOOL is exactly the same thing as bool while on all other devices (OS X, 32-bit iOS) it is signed char and cannot even be overridden by compiler flag -funsigned-char

It also means that this example code will run differently on different platforms (tested it myself):

int myValue = 256;
BOOL myBool = myValue;
if (myBool) {
    printf("i'm 64-bit iOS");
} else {
    printf("i'm 32-bit iOS");
}

BTW never assign things like array.count to BOOL variable because about 0.4% of possible values will be negative.

If some variables are stored in sqlite and you must use them in most activities in your app. then Application maybe the best way to achieve it. Query the variables from database when application started and store them in a field. Then you can use these variables in your activities.

So find the right way, and there is no best way.

As long as your List is a concrete class, you can simply call the contains() method as long as you have implemented your equals() method on MyItem.

// given 
// some input ... you to complete

// when
List<MyItems> results = service.getMyItems();

// then
assertTrue(results.contains(new MyItem("foo")));
assertTrue(results.contains(new MyItem("bar")));

Assumes you have implemented a constructor that accepts the values you want to assert on. I realise this isn't on a single line, but it's useful to know which value is missing rather than checking both at once.

I think people have put too much weight into the application logic versus protocol matter. The important thing is that the response should make sense. What if you have an API that serves a dynamic resource and a request is made for X which is derived from template Y with data Z and either Y or Z isn't currently available? Is that a business logic error or a technical error? The correct answer is, "who cares?"

Your API and your responses need to be intelligible and consistent. It should conform to some kind of spec, and that spec should define what a valid response is. Something that conforms to a valid response should yield a 200 code. Something that does not conform to a valid response should yield a 4xx or 5xx code indicative of why a valid response couldn't be generated.

If your spec's definition of a valid response permits { "error": "invalid ID" }, then it's a successful response. If your spec doesn't make that accommodation, it would be a poor decision to return that response with a 200 code.

I'd draw an analogy to calling a function parseFoo. What happens when you call parseFoo("invalid data")? Does it return an error result (maybe null)? Or does it throw an exception? Many will take a near-religious position on whether one approach or the other is correct, but ultimately it's up to the API specification.

"The status-code element is a three-digit integer code giving the result of the attempt to understand and satisfy the request"

Obviously there's a difference of opinion with regards to whether "successfully returning an error" constitutes an HTTP success or error. I see different people interpreting the same specs different ways. So pick a side, sure, but also accept that either way the whole world isn't going to agree with you. Me? I find myself somewhere in the middle, but I'll offer some commonsense considerations.

1. If your server-side code catches an unexpected exception when dispatching a request, that sounds like the very definition of a 500 Internal Server Error. This seems to be OP's situation. The application should not return a 200 for unexpected errors, but also see point 3.
2. If your server-side code should be able to gracefully handle a given invalid input, and it doesn't constitute an "exceptional" error condition, your spec should accommodate HTTP 200 responses that provide meaningful diagnostic information.
3. Above all: Have a spec. Make it consistent. Stick to it.

In OP's situation, it sounds like you have a de-facto standard that unhandled exceptions yield a 200 with a distinguishable response body. It's not ideal, but if it's not breaking things and actively causing problems, you probably have bigger, more important problems to solve.

Java 8:

LocalDateTime toDate = LocalDateTime.now();
LocalDateTime fromDate = LocalDateTime.of(toDate.getYear(), toDate.getMonth(), 
toDate.getDayOfMonth(), 0, 0, 0);
long millis = ChronoUnit.MILLIS.between(fromDate, toDate);

your code used in python2.x, you can use like this:

from urllib.request import urlopen
urlopen(url)

by the way, suggest another module called requests is more friendly to use, you can use pip install it, and use like this:

import requests
requests.get(url)
requests.post(url)

I thought it is easily to use, i am beginner too....hahah

You still have access to StreamWriter:

using (System.IO.StreamWriter file = new System.IO.StreamWriter(@"\hereIam.txt"))
{
    file.WriteLine(sb.ToString()); // "sb" is the StringBuilder
}

From the MSDN documentation: Writing to a Text File (Visual C#).

For newer versions of the .NET Framework (Version 2.0. onwards), this can be achieved with one line using the File.WriteAllText method.

System.IO.File.WriteAllText(@"C:\TextFile.txt", stringBuilder.ToString());

<img src="w3schools.jpg" alt="W3Schools.com" width="104" height="142">

In above html tag we have different attributes like src, alt, width and height.

If you want to get the any attribute value from above html tag you have to pass attribute value in getAttribute() method

Syntax:

getAttribute(attributeValue)
getAttribute(src) you get w3schools.jpg
getAttribute(height) you get 142
getAttribute(width) you get 104 

select group_id, 
       listagg(name, ',') within group (order by name) as names
       over (partition by group_id)   
from demotable
group by group_id 

def valid = pointAddress.findAll { a ->
    validPointTypes.any { a.contains(it) }
}

Should do it

Most probably you have space in your resultant path.

You can work around this by quoting the paths, thus allowing spaces. For example:

xcopy "$(SolutionDir)\Folder Name\File To Copy.ext" "$(TargetDir)" /R /Y /I

It's simple with open source 7zip SFX-Packager - easy way to just "Drag & drop" folders onto it, and it creates a portable/self-extracting package.

Another method (thanks osse), if you just want to know whether or not it exists:

if git rev-parse @{u} > /dev/null 2>&1
then
  printf "has an upstream\n"
else
  printf "has no upstream\n"
fi

Try running task manager to determine if your program is still running.

If it is running then stop it and run it again. the [Error] ld returned 1 exit status will not come back

The $(document).ready() is a jQuery event which occurs when the HTML document has been fully loaded, while the window.onload event occurs later, when everything including images on the page loaded.

Also window.onload is a pure javascript event in the DOM, while the $(document).ready() event is a method in jQuery.

$(document).ready() is usually the wrapper for jQuery to make sure the elements all loaded in to be used in jQuery...

Look at to jQuery source code to understand how it's working:

jQuery.ready.promise = function( obj ) {
    if ( !readyList ) {

        readyList = jQuery.Deferred();

        // Catch cases where $(document).ready() is called after the browser event has already occurred.
        // we once tried to use readyState "interactive" here, but it caused issues like the one
        // discovered by ChrisS here: http://bugs.jquery.com/ticket/12282#comment:15
        if ( document.readyState === "complete" ) {
            // Handle it asynchronously to allow scripts the opportunity to delay ready
            setTimeout( jQuery.ready );

        // Standards-based browsers support DOMContentLoaded
        } else if ( document.addEventListener ) {
            // Use the handy event callback
            document.addEventListener( "DOMContentLoaded", completed, false );

            // A fallback to window.onload, that will always work
            window.addEventListener( "load", completed, false );

        // If IE event model is used
        } else {
            // Ensure firing before onload, maybe late but safe also for iframes
            document.attachEvent( "onreadystatechange", completed );

            // A fallback to window.onload, that will always work
            window.attachEvent( "onload", completed );

            // If IE and not a frame
            // continually check to see if the document is ready
            var top = false;

            try {
                top = window.frameElement == null && document.documentElement;
            } catch(e) {}

            if ( top && top.doScroll ) {
                (function doScrollCheck() {
                    if ( !jQuery.isReady ) {

                        try {
                            // Use the trick by Diego Perini
                            // http://javascript.nwbox.com/IEContentLoaded/
                            top.doScroll("left");
                        } catch(e) {
                            return setTimeout( doScrollCheck, 50 );
                        }

                        // detach all dom ready events
                        detach();

                        // and execute any waiting functions
                        jQuery.ready();
                    }
                })();
            }
        }
    }
    return readyList.promise( obj );
};
jQuery.fn.ready = function( fn ) {
    // Add the callback
    jQuery.ready.promise().done( fn );

    return this;
};

Also I have created the image below as a quick references for both:

Never use escape(). It's nothing to do with HTML-encoding. It's more like URL-encoding, but it's not even properly that. It's a bizarre non-standard encoding available only in JavaScript.

If you want an HTML encoder, you'll have to write it yourself as JavaScript doesn't give you one. For example:

function encodeHTML(s) {
    return s.replace(/&/g, '&amp;').replace(/</g, '&lt;').replace(/"/g, '&quot;');
}

However whilst this is enough to put your user_id in places like the input value, it's not enough for id because IDs can only use a limited selection of characters. (And % isn't among them, so escape() or even encodeURIComponent() is no good.)

You could invent your own encoding scheme to put any characters in an ID, for example:

function encodeID(s) {
    if (s==='') return '_';
    return s.replace(/[^a-zA-Z0-9.-]/g, function(match) {
        return '_'+match[0].charCodeAt(0).toString(16)+'_';
    });
}

But you've still got a problem if the same user_id occurs twice. And to be honest, the whole thing with throwing around HTML strings is usually a bad idea. Use DOM methods instead, and retain JavaScript references to each element, so you don't have to keep calling getElementById, or worrying about how arbitrary strings are inserted into IDs.

eg.:

function addChut(user_id) {
    var log= document.createElement('div');
    log.className= 'log';
    var textarea= document.createElement('textarea');
    var input= document.createElement('input');
    input.value= user_id;
    input.readonly= True;
    var button= document.createElement('input');
    button.type= 'button';
    button.value= 'Message';

    var chut= document.createElement('div');
    chut.className= 'chut';
    chut.appendChild(log);
    chut.appendChild(textarea);
    chut.appendChild(input);
    chut.appendChild(button);
    document.getElementById('chuts').appendChild(chut);

    button.onclick= function() {
        alert('Send '+textarea.value+' to '+user_id);
    };

    return chut;
}

You could also use a convenience function or JS framework to cut down on the lengthiness of the create-set-appends calls there.

ETA:

I'm using jQuery at the moment as a framework

OK, then consider the jQuery 1.4 creation shortcuts, eg.:

var log= $('<div>', {className: 'log'});
var input= $('<input>', {readOnly: true, val: user_id});
...

The problem I have right now is that I use JSONP to add elements and events to a page, and so I can not know whether the elements already exist or not before showing a message.

You can keep a lookup of user_id to element nodes (or wrapper objects) in JavaScript, to save putting that information in the DOM itself, where the characters that can go in an id are restricted.

var chut_lookup= {};
...

function getChut(user_id) {
    var key= '_map_'+user_id;
    if (key in chut_lookup)
        return chut_lookup[key];
    return chut_lookup[key]= addChut(user_id);
}

(The _map_ prefix is because JavaScript objects don't quite work as a mapping of arbitrary strings. The empty string and, in IE, some Object member names, confuse it.)

Here is another idea that allow you to affect other elements without considering any specific selector and by only using the :hover state of the main element.

For this, I will rely on the use of custom properties (CSS variables). As we can read in the specification:

Custom properties are ordinary properties, so they can be declared on any element, are resolved with the normal inheritance and cascade rules ...

The idea is to define custom properties within the main element and use them to style child elements and since these properties are inherited we simply need to change them within the main element on hover.

Here is an example:

#container {_x000D_
  width: 200px;_x000D_
  height: 30px;_x000D_
  border: 1px solid var(--c);_x000D_
  --c:red;_x000D_
}_x000D_
#container:hover {_x000D_
  --c:blue;_x000D_
}_x000D_
#container > div {_x000D_
  width: 30px;_x000D_
  height: 100%;_x000D_
  background-color: var(--c);_x000D_
}

<div id="container">_x000D_
  <div>_x000D_
  </div>_x000D_
</div>

Why this can be better than using specific selector combined with hover?

I can provide at least 2 reasons that make this method a good one to consider:

1. If we have many nested elements that share the same styles, this will avoid us complex selector to target all of them on hover. Using Custom properties, we simply change the value when hovering on the parent element.
2. A custom property can be used to replace a value of any property and also a partial value of it. For example we can define a custom property for a color and we use it within a border, linear-gradient, background-color, box-shadow etc. This will avoid us reseting all these properties on hover.

Here is a more complex example:

.container {_x000D_
  --c:red;_x000D_
  width:400px;_x000D_
  display:flex;_x000D_
  border:1px solid var(--c);_x000D_
  justify-content:space-between;_x000D_
  padding:5px;_x000D_
  background:linear-gradient(var(--c),var(--c)) 0 50%/100% 3px no-repeat;_x000D_
}_x000D_
.box {_x000D_
  width:30%;_x000D_
  background:var(--c);_x000D_
  box-shadow:0px 0px 5px var(--c);_x000D_
  position:relative;_x000D_
}_x000D_
.box:before {_x000D_
  content:"A";_x000D_
  display:block;_x000D_
  width:15px;_x000D_
  margin:0 auto;_x000D_
  height:100%;_x000D_
  color:var(--c);_x000D_
  background:#fff;_x000D_
}_x000D_
_x000D_
/*Hover*/_x000D_
.container:hover {_x000D_
  --c:blue;_x000D_
}

<div class="container">_x000D_
<div class="box"></div>_x000D_
<div class="box"></div>_x000D_
</div>

As we can see above, we only need one CSS declaration in order to change many properties of different elements.

Microsoft SQL Server Integration Services (SSIS) is a platform for building high-performance data integration solutions, including extraction, transformation, and load (ETL) packages for data warehousing. SSIS includes graphical tools and wizards for building and debugging packages; tasks for performing workflow functions such as FTP operations, executing SQL statements, and sending e-mail messages; data sources and destinations for extracting and loading data; transformations for cleaning, aggregating, merging, and copying data; a management database, SSISDB, for administering package execution and storage; and application programming interfaces (APIs) for programming the Integration Services object model.

Another option that may be suitable in this situation is using XML

The XML option to transposing rows into columns is basically an optimal version of the PIVOT in that it addresses the dynamic column limitation. 

The XML version of the script addresses this limitation by using a combination of XML Path, dynamic T-SQL and some built-in functions (i.e. STUFF, QUOTENAME).

Vertical expansion

Similar to the PIVOT and the Cursor, newly added policies are able to be retrieved in the XML version of the script without altering the original script.

Horizontal expansion

Unlike the PIVOT, newly added documents can be displayed without altering the script.

Performance breakdown

In terms of IO, the statistics of the XML version of the script is almost similar to the PIVOT – the only difference is that the XML has a second scan of dtTranspose table but this time from a logical read – data cache.

You can find some more about these solutions (including some actual T-SQL exmaples) in this article: https://www.sqlshack.com/multiple-options-to-transposing-rows-into-columns/

you could access the data using $('#prod')[0].dataset

ORDER_BY cast(registration_no as unsigned) ASC

explicitly converts the value to a number. Another possibility to achieve the same would be

ORDER_BY registration_no + 0 ASC

which will force an implicit conversation.

Actually you should check the table definition and change it. You can change the data type to int like this

ALTER TABLE your_table MODIFY COLUMN registration_no int;

youredittext.requestFocus() call it from activity

oncreate();

and use the above code there

I would also take a look at CloudMade's developer tools. They offer a beautifully styled OSM base map service, an OpenLayers plugin, and even their own light-weight, very fast JavaScript mapping client. They also host their own routing service, which you mentioned as a possible requirement. They have great documentation and examples.

I won't reiterate tons of good (and some bad) information already answered in other answers and comments, but I will answer your followup question with a tip:

When would someone use one of these?

Use decimal for counted values

Use float/double for measured values

Some examples:

• money (do we count money or measure money?)

• distance (do we count distance or measure distance? *)

• scores (do we count scores or measure scores?)

We always count money and should never measure it. We usually measure distance. We often count scores.

* In some cases, what I would call nominal distance, we may indeed want to 'count' distance. For example, maybe we are dealing with country signs that show distances to cities, and we know that those distances never have more than one decimal digit (xxx.x km).

My answer will focus on WHEN we can use while/for-else.

At the first glance, it seems there is no different when using

while CONDITION:
    EXPRESSIONS
print 'ELSE'
print 'The next statement'

and

while CONDITION:
    EXPRESSIONS
else:
    print 'ELSE'
print 'The next statement'

Because the print 'ELSE' statement seems always executed in both cases (both when the while loop finished or not run).

Then, it's only different when the statement print 'ELSE' will not be executed. It's when there is a breakinside the code block under while

In [17]: i = 0

In [18]: while i < 5:
    print i
    if i == 2:
        break
    i = i +1
else:
    print 'ELSE'
print 'The next statement'
   ....:
0
1
2
The next statement

If differ to:

In [19]: i = 0

In [20]: while i < 5:
    print i
    if i == 2:
        break
    i = i +1
print 'ELSE'
print 'The next statement'
   ....:
0
1
2
ELSE
The next statement

return is not in this category, because it does the same effect for two above cases.

exception raise also does not cause difference, because when it raises, where the next code will be executed is in exception handler (except block), the code in else clause or right after the while clause will not be executed.

We have found that adding the Apptentive cocoa pod to an existing Xcode project may potentially not include some of our required frameworks.

Check your linker flags:

Target > Build Settings > Other Linker Flags 

You should see -lApptentiveConnect listed as a linker flag:

... -ObjC -lApptentiveConnect ... 

You should also see our required Frameworks listed:

• Accelerate
• CoreData
• CoreText
• CoreGraphics
• CoreTelephony
• Foundation
• QuartzCore
• StoreKit
• SystemConfiguration

• UIKit

  -ObjC -lApptentiveConnect -framework Accelerate -framework CoreData -framework CoreGraphics -framework CoreText -framework Foundation -framework QuartzCore -framework SystemConfiguration -framework UIKit -framework CoreTelephony -framework StoreKit  

In my case, another developer had removed some of the tables from the underlying database. When I realised this, and removed these tables from the entity, the problem was solved. Wasn't as obvious as it sounds.

var SendInfo= { SendInfo: [... your elements ...]};

        $.ajax({
            type: 'post',
            url: 'Your-URI',
            data: JSON.stringify(SendInfo),
            contentType: "application/json; charset=utf-8",
            traditional: true,
            success: function (data) {
                ...
            }
        });

and in action

public ActionResult AddDomain(IEnumerable<PersonSheets> SendInfo){
...

you can bind your array like this

var SendInfo = [];

$(this).parents('table').find('input:checked').each(function () {
    var domain = {
        name: $("#id-manuf-name").val(),
        address: $("#id-manuf-address").val(),
        phone: $("#id-manuf-phone").val(),
    }

    SendInfo.push(domain);
});

hope this can help you.

Given worked for me.

document.querySelectorAll(".widget.hover").forEach(obj=>obj.classList.remove("hover"));

You can do as follows:

1. Get difference of dates(Difference will be in milliseconds)
2. Convert milliseconds into minutes i-e ms/1000/60

The Code:

let dateOne = new Date("2020-07-10");
let dateTwo = new Date("2020-07-11");

let msDifference =  dateTwo - dateOne;
let minutes = Math.floor(msDifference/1000/60);
console.log("Minutes between two dates =",minutes);

I used DateTime.Now.TimeOfDay.TotalMilliseconds (for current day), hope it helps you out as well.

static

is used for making the variable a class variable. You need not define a static variable while declaring.

Example:

#include <iostream>

class dummy
{
        public:
                static int dum;
};


int dummy::dum = 0; //This is important for static variable, otherwise you'd get a linking error

int main()
{
        dummy d;
        d.dum = 1;

        std::cout<<"Printing dum from object: "<<d.dum<<std::endl;
        std::cout<<"Printing dum from class: "<<dummy::dum<<std::endl;

        return 0;
}

This would print: Printing dum from object: 1 Printing dum from class: 1

The variable dum is a class variable. Trying to access it via an object just informs the compiler that it is a variable of which class. Consider a scenario where you could use a variable to count the number of objects created. static would come in handy there.

const

is used to make it a read-only variable. You need to define and declare the const variable at once.

In the same program mentioned above, let's make the dum a const as well:

class dummy
{
        public:
                static const int dum; // This would give an error. You need to define it as well
                static const int dum = 1; //this is correct
                const int dum = 1; //Correct. Just not making it a class variable

};

Suppose in the main, I am doing this:

int main()
{
        dummy d;
        d.dum = 1; //Illegal!

        std::cout<<"Printing dum from object: "<<d.dum<<std::endl;
        std::cout<<"Printing dum from class: "<<dummy::dum<<std::endl;

        return 0;
}

Though static has been manageable to understand, const is messed up in c++. The following resource helps in understanding it better: http://duramecho.com/ComputerInformation/WhyHowCppConst.html

You can use this QString constructor for conversion from QByteArray to QString:

QString(const QByteArray &ba)

QByteArray data;
QString DataAsString = QString(data);

Make sure overflow is set to "scroll" not "auto." With that said, in OS X Lion, overflow set to "scroll" behaves more like auto in that scrollbars will still only show when being used. So if any the solutions above don't appear to be working that might be why.

This is what you'll need to fix it:

::-webkit-scrollbar {
  -webkit-appearance: none;
  width: 7px;
}
::-webkit-scrollbar-thumb {
  border-radius: 4px;
  background-color: rgba(0, 0, 0, .5);
  -webkit-box-shadow: 0 0 1px rgba(255, 255, 255, .5);
}

You can style it accordingly if you don't like the default.

With C# 8 onwards you can make it even more concise with the new switch. And with the use of discard option _ you can avoid creating innecesary variables when you don't need them, like this:

        return document switch {
            Invoice _ => "Is Invoice",
            ShippingList _ => "Is Shipping List",
            _ => "Unknown"
        };

Invoice and ShippingList are classes and document is an object that can be either of them.

Take an input float as left. Then take the button and float it right. You can clearfix class when you take more than one to distance.

<input style="width:65%;float:left"class="btn btn-primary" type="text" name="name"> 
<div style="width:8%;float:left">&nbsp;</div>
<button class="btn btn-default" type="button">Go!</button>
<div class="clearfix" style="margin-bottom:10px"> </div>

From the man read:

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

Input parameters:

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

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

• size_t count maximum number of characters to read

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

char buf[1];

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

for (i in 1:names(DF){
    DF[[i]] <- as.numeric(DF[[i]])
}

I solved this using double brackets [[]]

Why strtok() is a bad idea

Do not use strtok() in normal code, strtok() uses static variables which have some problems. There are some use cases on embedded microcontrollers where static variables make sense but avoid them in most other cases. strtok() behaves unexpected when more than 1 thread uses it, when it is used in a interrupt or when there are some other circumstances where more than one input is processed between successive calls to strtok(). Consider this example:

#include <stdio.h>
#include <string.h>

//Splits the input by the / character and prints the content in between
//the / character. The input string will be changed
void printContent(char *input)
{
    char *p = strtok(input, "/");
    while(p)
    {
        printf("%s, ",p);
        p = strtok(NULL, "/");
    }
}

int main(void)
{
    char buffer[] = "abc/def/ghi:ABC/DEF/GHI";
    char *p = strtok(buffer, ":");
    while(p)
    {
        printContent(p);
        puts(""); //print newline
        p = strtok(NULL, ":");
    }
    return 0;
}

You may expect the output:

abc, def, ghi,
ABC, DEF, GHI,

But you will get

abc, def, ghi,

This is because you call strtok() in printContent() resting the internal state of strtok() generated in main(). After returning, the content of strtok() is empty and the next call to strtok() returns NULL.

What you should do instead

You could use strtok_r() when you use a POSIX system, this versions does not need static variables. If your library does not provide strtok_r() you can write your own version of it. This should not be hard and Stackoverflow is not a coding service, you can write it on your own.

If your application often uses http protocol then REST is best because of its light weight, and knowing that your application uses only http protocol choosing SOAP is not so good because it heavy,Better to make decision on web service selection based on the protocols we use in our applications.

Try this method to convert a 'string that could potentially contain html code' to 'text format':

$msg = "<div></div>";
$safe_msg = htmlspecialchars($msg, ENT_QUOTES);
echo $safe_msg;

Hope this helps!

I just want to add here that if any one want to call a function on load event of div & you don't want to use jQuery(due to conflict as in my case) then simply call a function after all the html code or any other code you have written including the function code and simply call a function .

/* All Other Code*/
-----
------
/* ----At the end ---- */
<script type="text/javascript">
   function_name();
</script>

OR

/* All Other Code*/

------
/* ----At the end ---- */
<script type="text/javascript">
 function my_func(){
   function definition;      

  }

 my_func();
</script>

The always @* would never trigger as no Right hand arguments change. Why not use a wire with assign?

module top (
    input wire clk,
    output wire [7:0] led   
);

wire [7:0] data_reg ; 
assign data_reg   = 8'b10101011;
assign led        = data_reg;

endmodule

If you actually want a flop where you can change the value, the default would be in the reset clause.

module top
(
    input        clk,
    input        rst_n,
    input  [7:0] data,
    output [7:0] led   
 );

reg [7:0] data_reg ; 
always @(posedge clk or negedge rst_n) begin
  if (!rst_n)
    data_reg <= 8'b10101011;
  else
    data_reg <= data ; 
end

assign led = data_reg;

endmodule

Hope this helps

This answers what the OP should have asked, i.e. traverse a list comparing consecutive elements (excellent SilentGhost answer), yet generalized for any group (n-gram): 2, 3, ... n:

zip(*(l[start:] for start in range(0, n)))

Examples:

l = range(0, 4)  # [0, 1, 2, 3]

list(zip(*(l[start:] for start in range(0, 2)))) # == [(0, 1), (1, 2), (2, 3)]
list(zip(*(l[start:] for start in range(0, 3)))) # == [(0, 1, 2), (1, 2, 3)]
list(zip(*(l[start:] for start in range(0, 4)))) # == [(0, 1, 2, 3)]
list(zip(*(l[start:] for start in range(0, 5)))) # == []

Explanations:

• l[start:] generates a a list/generator starting from index start
• *list or *generator: passes all elements to the enclosing function zip as if it was written zip(elem1, elem2, ...)

Note:

AFAIK, this code is as lazy as it can be. Not tested.

You can open it in a new window with window.open('https://support.wwf.org.uk/earth_hour/index.php?type=individual');. If you want to open it in new tab open the current page in two tabs and then alllow the script to run so that both current page and the new page will be obtained.

You can migrate to XDocument instead of XmlDocument and then use Linq if you prefer that syntax. Something like:

var q = (from myConfig in xDoc.Elements("MyConfiguration")
         select myConfig.Attribute("SuperString").Value)
         .First();

I know this is old post but JsonConvert actually has a different method so it would be

var product = new { Name = "", Price = 0 };
var jsonResponse = JsonConvert.DeserializeAnonymousType(json, product);

I consider a modern IDE to be critical for understanding large scala projects. Since these operators are also methods, in intellij idea I just control-click or control-b into the definitions.

You can control-click right into a cons operator (::) and end up at the scala javadoc saying "Adds an element at the beginning of this list." In user-defined operators, this becomes even more critical, since they could be defined in hard-to-find implicits... your IDE knows where the implicit was defined.

You can use a bind variable at the SQLPlus level to do this. Of course you have little control over the formatting of the output.

VAR x REFCURSOR;
EXEC GetGrantListByPI(args, :x);
PRINT x;

There's a clone snippet here, which you can add to your model which does this:

def clone(self):
  new_kwargs = dict([(fld.name, getattr(old, fld.name)) for fld in old._meta.fields if fld.name != old._meta.pk]);
  return self.__class__.objects.create(**new_kwargs)

round($number, -1);

This will round $number to the nearest 10. You can also pass a third variable if necessary to change the rounding mode.

Type it in one cell, copy that cell, select all the cells you want to fill, and paste.

Alternatively, type it in one cell, select the black square in the bottom-right of that cell, and drag down.

If you dont need a feedback about the requested data and also dont need any interactivity between the opener and the popup, you can post a hidden form into the popup:

Example:

<form method="post" target="popup" id="formID" style="display:none" action="https://example.com/barcode/generate" >
  <input type="hidden" name="packing_slip" value="35592" />
  <input type="hidden" name="reference" value="0018439" />
  <input type="hidden" name="total_boxes" value="1" />
</form>
<script type="text/javascript">
window.open('about:blank','popup','width=300,height=200')
document.getElementById('formID').submit();
</script>

Otherwise you could use jsonp. But this works only, if you have access to the other Server, because you have to modify the response.

For the correct and efficient computation of the hash value of a file (in Python 3):

• Open the file in binary mode (i.e. add 'b' to the filemode) to avoid character encoding and line-ending conversion issues.
• Don't read the complete file into memory, since that is a waste of memory. Instead, sequentially read it block by block and update the hash for each block.
• Eliminate double buffering, i.e. don't use buffered IO, because we already use an optimal block size.
• Use readinto() to avoid buffer churning.

Example:

import hashlib

def sha256sum(filename):
    h  = hashlib.sha256()
    b  = bytearray(128*1024)
    mv = memoryview(b)
    with open(filename, 'rb', buffering=0) as f:
        for n in iter(lambda : f.readinto(mv), 0):
            h.update(mv[:n])
    return h.hexdigest()

Once you have a JArray you can treat it just like any other Enumerable object, and using linq you can access them, check them, verify them, and select them.

var str = @"[1, 2, 3]";
var jArray = JArray.Parse(str);
Console.WriteLine(String.Join("-", jArray.Where(i => (int)i > 1).Select(i => i.ToString())));

github adds a reference to the commit if it contains #issuenbr (discovered this by chance).

If everything works as it should it shouldn't, BUT we all know everything doesn't work the way it should especially when it comes to the query optimizer, query plan caching and statistics.

First I would suggest rebuilding index and statistics, then clearing the query plan cache just to make sure that's not screwing things up. However I've experienced problems even when that's done.

I've experienced some cases where a left join has been faster than a inner join.

The underlying reason is this: If you have two tables and you join on a column with an index (on both tables). The inner join will produce the same result no matter if you loop over the entries in the index on table one and match with index on table two as if you would do the reverse: Loop over entries in the index on table two and match with index in table one. The problem is when you have misleading statistics, the query optimizer will use the statistics of the index to find the table with least matching entries (based on your other criteria). If you have two tables with 1 million in each, in table one you have 10 rows matching and in table two you have 100000 rows matching. The best way would be to do an index scan on table one and matching 10 times in table two. The reverse would be an index scan that loops over 100000 rows and tries to match 100000 times and only 10 succeed. So if the statistics isn't correct the optimizer might choose the wrong table and index to loop over.

If the optimizer chooses to optimize the left join in the order it is written it will perform better than the inner join.

BUT, the optimizer may also optimize a left join sub-optimally as a left semi join. To make it choose the one you want you can use the force order hint.

Just declare the variable at class or script scope, then access it from inside your methods or closures. Without an example, it's hard to be more specific for your particular problem though.

However, global variables are generally considered bad form.

Why not return the variable from one function, then pass it into the next?

An example use-case to plot CPU usage in real-time.

import time
import psutil
import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.add_subplot(111)

i = 0
x, y = [], []

while True:
    x.append(i)
    y.append(psutil.cpu_percent())

    ax.plot(x, y, color='b')

    fig.canvas.draw()

    ax.set_xlim(left=max(0, i - 50), right=i + 50)
    fig.show()
    plt.pause(0.05)
    i += 1

You won't find anything overlaying GDB which can compete with the raw power of the Visual Studio debugger. It's just too powerful, and it's just too well integrated inside the IDE.

For a Linux alternative, try DDD if free software is your thing.

One important thing for passing multidimensional arrays is:

• First array dimension need not be specified.
• Second(any any further)dimension must be specified.

1.When only second dimension is available globally (either as a macro or as a global constant)

const int N = 3;

void print(int arr[][N], int m)
{
int i, j;
for (i = 0; i < m; i++)
  for (j = 0; j < N; j++)
    printf("%d ", arr[i][j]);
}

int main()
{
int arr[][3] = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};
print(arr, 3);
return 0;
}

2.Using a single pointer: In this method,we must typecast the 2D array when passing to function.

void print(int *arr, int m, int n)
{
int i, j;
for (i = 0; i < m; i++)
  for (j = 0; j < n; j++)
    printf("%d ", *((arr+i*n) + j));
 }

int main()
{
int arr[][3] = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};
int m = 3, n = 3;

// We can also use "print(&arr[0][0], m, n);"
print((int *)arr, m, n);
return 0;
}

You should edit your my.cnf

tmpdir = /whatewer/you/want

and after that restart mysql

P.S. Don't forget give write permissions to /whatewer/you/want for mysql user

Use SequenceEqual to check for sequence equality because Equals method checks for reference equality.

var a = ints1.SequenceEqual(ints2);

Or if you don't care about elements order use Enumerable.All method:

var a = ints1.All(ints2.Contains);

The second version also requires another check for Count because it would return true even if ints2 contains more elements than ints1. So the more correct version would be something like this:

var a = ints1.All(ints2.Contains) && ints1.Count == ints2.Count;

In order to check inequality just reverse the result of All method:

var a = !ints1.All(ints2.Contains)

I am parsing .il files generated by ildasm to build a database of assemnblies, classes, methods, and stored procedures for use doing a conversion. I came across the following, which broke my parsing.

The book Expert .NET 2.0 IL Assembler, by Serge Lidin, Apress, published 2006, Chapter 8, Primitive Types and Signatures, pp. 149-150 explains.

<type>[] is termed a Vector of <type>,

<type>[<bounds> [<bounds>**] ] is termed an array of <type>

** means may be repeated, [ ] means optional.

Examples: Let <type> = int32.

1) int32[...,...] is a two-dimensional array of undefined lower bounds and sizes

2) int32[2...5] is a one-dimensional array of lower bound 2 and size 4.

3) int32[0...,0...] is a two-dimensional array of lower bounds 0 and undefined size.

It looks like you were on the right path. Here is the one-liner you were looking for:

df.reset_index().T.drop_duplicates().T

But since there is no example data frame that produces the referenced error message Reindexing only valid with uniquely valued index objects, it is tough to say exactly what would solve the problem. if restoring the original index is important to you do this:

original_index = df.index.names
df.reset_index().T.drop_duplicates().reset_index(original_index).T

System.out.println(LocalDate.now().format(DateTimeFormatter.ofPattern("dd.MMMM yyyy")));

The above answer shows it for today

The below changes fixed my problem. I struggled with the same error for a week. I would like to share with you all that the solution is simply host = '' in the server and the client host = ip of the server.  

No. But it's relatively trivial to achieve using sscanf in a loop.

Sometimes this occurs when you have the folder of the package you are trying to restore inside the "packages" folder (i.e. "Packages/EntityFramework.6.0.0/") but the "DLLs" are not inside it (most of the version control systems automatically ignore ".dll" files). This occurs because before NuGet tries to restore each package it checks if the folders already exist, so if it exists, NuGet assumes that the "dll" is inside it. So if this is the problem for you just delete the folder that NuGet will restore it correctly.

You could just use list comprehension:

property_asel = [val for is_good, val in zip(good_objects, property_a) if is_good]

or

property_asel = [property_a[i] for i in good_indices]

The latter one is faster because there are fewer good_indices than the length of property_a, assuming good_indices are precomputed instead of generated on-the-fly.

Edit: The first option is equivalent to itertools.compress available since Python 2.7/3.1. See @Gary Kerr's answer.

property_asel = list(itertools.compress(property_a, good_objects))

If you need the output in a file you can use a redirect:

curl https://vi.stackexchange.com/ -vs >curl-output.txt 2>&1

Please be sure not to flip the >curl-output.txt and 2>&1, which will not work due to bash's redirection behavior.

../../../includes/boot.inc.php

Each instance of ../ means up/back one directory.

After, or in-between your text, use the   (non-breaking space) extended HTML character.

• EG 1 :

  This is an example paragraph.    This is the next line.

I have a similar problem and I resolved in this way:

@RequestMapping(value = "{siteCode}/**/{fileName}.{fileExtension}")
public HttpEntity<byte[]> getResource(@PathVariable String siteCode,
        @PathVariable String fileName, @PathVariable String fileExtension,
        HttpServletRequest req, HttpServletResponse response ) throws IOException {
    String fullPath = req.getPathInfo();
    // Calling http://localhost:8080/SiteXX/images/argentine/flag.jpg
    // fullPath conentent: /SiteXX/images/argentine/flag.jpg
}

Note that req.getPathInfo() will return the complete path (with {siteCode} and {fileName}.{fileExtension}) so you will have to process conveniently.

The best, quickest and easiest way to resolve the comma in data issue is to use Excel to save a comma separated file after having set Windows' list separator setting to something other than a comma (such as a pipe). This will then generate a pipe (or whatever) separated file for you that you can then import. This is described here.

Couldn't find any official documentation (no surprise there) but according to this interesting article, those elements are injected in order to enable Word to convert the HTML back to fully compatible Word document, with everything preserved.

The relevant paragraph:

Microsoft added the special tags to Word's HTML with an eye toward backward compatibility. Microsoft wanted you to be able to save files in HTML complete with all of the tracking, comments, formatting, and other special Word features found in traditional DOC files. If you save a file in HTML and then reload it in Word, theoretically you don't loose anything at all.

This makes lots of sense.

For your specific question.. the o in the <o:p> means "Office namespace" so anything following the o: in a tag means "I'm part of Office namespace" - in case of <o:p> it just means paragraph, the equivalent of the ordinary <p> tag.

I assume that every HTML tag has its Office "equivalent" and they have more.

Divide and Conquer

• In this problem is solved in following three steps: 1. Divide - Dividing into number of sub-problems 2. Conquer - Conquering by solving sub-problems recursively 3. Combine - Combining sub-problem solutions to get original problem's solution
• Recursive approach
• Top Down technique
• Example: Merge Sort

Dynamic Programming

• In this the problem is solved in following steps: 1. Defining structure of optimal solution 2. Defines value of optimal solutions repeatedly. 3. Obtaining values of optimal solution in bottom-up fashion 4. Getting final optimal solution from obtained values
• Non-Recursive
• Bottom Up Technique
• Example: Strassen's Matrix Multiplication

I think your solution would be to wrap your content container and your sidebar in a parent containing div. Float your sidebar to the left and give it the background image. Create a wide margin at least the width of your sidebar for your content container. Add clearing a float hack to make it all work.

First off, please note that I haven't used either of them (but have used Node.js).

Both libraries are documented quite well and have a stable API. However, persistence.js seems to be used in more projects. I don't know if all of them still use it, though.

The developer of sequelize sometimes blogs about it at blog.depold.com. When you'd like to use primary keys as foreign keys, you'll need the patch that's described in this blog post. If you'd like help for persistence.js there is a google group devoted to it.

From the examples I gather that sequelize is a bit more JavaScript-like (more sugar) than persistance.js but has support for fewer datastores (only MySQL, while persistance.js can even use in-browser stores).

I think that sequelize might be the way to go for you, as you only need MySQL support. However, if you need some convenient features (for instance search) or want to use a different database later on you'd need to use persistence.js.

I was struggling to get this to work for a while. Once you change the extension to .pyw, make sure that you open properties of the file and direct the "open with" path to pythonw.exe.

git branch --set-upstream <remote-branch>

sets the default remote branch for the current local branch.

Any future git pull command (with the current local branch checked-out),
will attempt to bring in commits from the <remote-branch> into the current local branch.

One way to avoid having to explicitly type --set-upstream is to use its shorthand flag -u as follows:

git push -u origin local-branch

This sets the upstream association for any future push/pull attempts automatically.
For more details, checkout this detailed explanation about upstream branches and tracking.

To avoid confusion, recent versions of git deprecate this somewhat ambiguous --set-upstream option in favour of a more verbose --set-upstream-to option with identical syntax and behaviour

git branch --set-upstream-to <origin/remote-branch>

You can use diff tool in linux to compare two files. You can use --changed-group-format and --unchanged-group-format options to filter required data.

Following three options can use to select the relevant group for each option:

• '%<' get lines from FILE1

• '%>' get lines from FILE2

• '' (empty string) for removing lines from both files.

E.g: diff --changed-group-format="%<" --unchanged-group-format="" file1.txt file2.txt

[root@vmoracle11 tmp]# cat file1.txt 
test one
test two
test three
test four
test eight
[root@vmoracle11 tmp]# cat file2.txt 
test one
test three
test nine
[root@vmoracle11 tmp]# diff --changed-group-format='%<' --unchanged-group-format='' file1.txt file2.txt 
test two
test four
test eight

Have you tried something like this? Put it in the head for it to work properly.

<script type="text/javascript">
    document.addEventListener("DOMContentLoaded", function(){
         //using DOMContentLoaded is good as it relies on the DOM being ready for
         //manipulation, rather than the windows being fully loaded. Just like
         //how jQuery's $(document).ready() does it.

         //loop through your inputs and set their values here
    }, false);
</script>

The client machine needs a proper font that has a glyph for this character to display it. But Times New Roman doesn’t. Try Arial Unicode MS or Lucida Grande instead:

<span style="font-family: Arial Unicode MS, Lucida Grande">

</span>

This works for me on Windows XP in IE 5.5, IE 6.0, FF 3.0.6.

IE11 does implement String.prototype.includes so why not using the official Polyfill?

Source: polyfill source

  if (!String.prototype.includes) {
    String.prototype.includes = function(search, start) {
      if (typeof start !== 'number') {
        start = 0;
      }

      if (start + search.length > this.length) {
        return false;
      } else {
        return this.indexOf(search, start) !== -1;
      }
    };
  }

You can't call "printf" with a std::string in parameter. The "%s" is designed for C-style string : char* or char []. In C++ you can do like that :

#include <iostream>
std::cout << YourString << std::endl;

If you absolutely want to use printf, you can use the "c_str()" method that give a char* representation of your string.

printf("%s\n",YourString.c_str())

For CMD one line LF-only:

powershell -NoProfile -command "((Get-Content 'prueba1.txt') -join \"`n\") + \"`n\" | Set-Content -NoNewline 'prueba1.txt'"

so you can create a .bat

It turns out to get this application working under VBScript, I had to do two things.

So in doing a shift rather than multiplication/division by a power of two in python, there's a slight improvement (~10% for division; ~1% for multiplication). If its a non-power of two, there's likely a considerable slowdown.

Again these #s will change depending on your processor, your compiler (or interpreter -- did in python for simplicity).

As with everyone else, don't prematurely optimize. Write very readable code, profile if its not fast enough, and then try to optimize the slow parts. Remember, your compiler is much better at optimization than you are.

upload_max_filesize is the limit of any single file. post_max_size is the limit of the entire body of the request, which could include multiple files.

Given post_max_size = 20M and upload_max_filesize = 6M you could upload up to 3 files of 6M each. If instead post_max_size = 6M and upload_max_filesize = 20M then you could only upload one 6M file before hitting post_max_size. It doesn't help to have upload_max_size > post_max_size.

It's not obvious how to recognize going over post_max_size. $_POST and $_FILES will be empty, but $_SERVER['CONTENT_LENGTH'] will be > 0. If the client just didn't upload any post variables or files, then $_SERVER['CONTENT_LENGTH'] will be 0.

The note is firstly you must sure about filemode set to false in config git file, or use this command:

git config core.filemode false

and then you can set 0777 permission with this command:

git update-index --chmod=+x foo.sh

Another way to differentiate between 0 rows or some rows from a ResultSet:

ResultSet res = getData();

if(!res.isBeforeFirst()){          //res.isBeforeFirst() is true if the cursor
                                   //is before the first row.  If res contains
                                   //no rows, rs.isBeforeFirst() is false.

    System.out.println("0 rows");
}
else{
    while(res.next()){
        // code to display the rows in the table.
    }
}

If you must know the number of rows given a ResultSet, here is a method to get it:

public int getRows(ResultSet res){
    int totalRows = 0;
    try {
        res.last();
        totalRows = res.getRow();
        res.beforeFirst();
    } 
    catch(Exception ex)  {
        return 0;
    }
    return totalRows ;    
}

As I haven't seen it at serverfault yet, and the answer is quite simple:

Change:

ssh -f -L3310:remote.server:3306 [email protected] -N

To:

ssh -f -L3310:localhost:3306 [email protected] -N

And change:

mysqldump -P 3310 -h localhost -u mysql_user -p database_name table_name

To:

mysqldump -P 3310 -h 127.0.0.1 -u mysql_user -p database_name table_name

(do not use localhost, it's one of these 'special meaning' nonsense that probably connects by socket rather then by port)

edit: well, to elaborate: if host is set to localhost, a configured (or default) --socket option is assumed. See the manual for which option files are sought / used. Under Windows, this can be a named pipe.

For those coming here from Google like I did, later versions of Powershell have a $foreach automatic variable. You can find the "current" object with $foreach.Current

Let say your html code is :

<input type="text" id="txtMyText" />

then the jquery should be :

$('#txtMyText').keyup(function() {
  this.value = this.value.toUpperCase();
});

Try:

public class ImageComponent extends JComponent {
  private final BufferedImage img;

  public ImageComponent(URL url) throws IOException {
    img = ImageIO.read(url);
    setPreferredSize(new Dimension(img.getWidth(), img.getHeight()));

  }

  @Override
  protected void paintComponent(Graphics g) {
    super.paintComponent(g);
    g.drawImage(img, 0, 0, img.getWidth(), img.getHeight(), this);
  }

  public static void main(String[] args) throws Exception {
    final URL kitten = new URL("https://placekitten.com/g/200/300");

    final ImageComponent image = new ImageComponent(kitten);

    JFrame frame = new JFrame("Test");
    frame.add(new JScrollPane(image));

    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setSize(400, 300);
    frame.setVisible(true);
  }
}

Only this answer would be useful to you if you have math, scientific formulae in your document. Even if you don't have them it works fine.

If I understand your questions correctly, all you need to do is add the .Where(m => m.r.u.UserId == 1):

    var UserInRole = db.UserProfiles.
        Join(db.UsersInRoles, u => u.UserId, uir => uir.UserId,
        (u, uir) => new { u, uir }).
        Join(db.Roles, r => r.uir.RoleId, ro => ro.RoleId, (r, ro) => new { r, ro })
        .Where(m => m.r.u.UserId == 1)
        .Select (m => new AddUserToRole
        {
            UserName = m.r.u.UserName,
            RoleName = m.ro.RoleName

There's no need to declare new variables in Python. If we're talking about variables in functions or modules, no declaration is needed. Just assign a value to a name where you need it: mymagic = "Magic". Variables in Python can hold values of any type, and you can't restrict that.

Your question specifically asks about classes, objects and instance variables though. The idiomatic way to create instance variables is in the __init__ method and nowhere else — while you could create new instance variables in other methods, or even in unrelated code, it's just a bad idea. It'll make your code hard to reason about or to maintain.

So for example:

class Thing(object):

    def __init__(self, magic):
        self.magic = magic

Easy. Now instances of this class have a magic attribute:

thingo = Thing("More magic")
# thingo.magic is now "More magic"

Creating variables in the namespace of the class itself leads to different behaviour altogether. It is functionally different, and you should only do it if you have a specific reason to. For example:

class Thing(object):

    magic = "Magic"

    def __init__(self):
        pass

Now try:

thingo = Thing()
Thing.magic = 1
# thingo.magic is now 1

Or:

class Thing(object):

    magic = ["More", "magic"]

    def __init__(self):
        pass

thing1 = Thing()
thing2 = Thing()
thing1.magic.append("here")
# thing1.magic AND thing2.magic is now ["More", "magic", "here"]

This is because the namespace of the class itself is different to the namespace of the objects created from it. I'll leave it to you to research that a bit more.

The take-home message is that idiomatic Python is to (a) initialise object attributes in your __init__ method, and (b) document the behaviour of your class as needed. You don't need to go to the trouble of full-blown Sphinx-level documentation for everything you ever write, but at least some comments about whatever details you or someone else might need to pick it up.

import matplotlib.pyplot as plt  
plt.rcParams.update({'figure.max_open_warning': 0})

If you use this, you won’t get that error, and it is the simplest way to do that.

Yes you can do it yourself. It is just a matter of grabbing the sources of the page and parsing them the way you want.

There are various possibilities. A good combo is using python-requests (built on top of urllib2, it is urllib.request in Python3) and BeautifulSoup4, which has its methods to select elements and also permits CSS selectors:

import requests
from BeautifulSoup4 import BeautifulSoup as bs
request = requests.get("http://foo.bar")
soup = bs(request.text) 
some_elements = soup.find_all("div", class_="myCssClass")

Some will prefer xpath parsing or jquery-like pyquery, lxml or something else.

When the data you want is produced by some JavaScript, the above won't work. You either need python-ghost or Selenium. I prefer the latter combined with PhantomJS, much lighter and simpler to install, and easy to use:

from selenium import webdriver
client = webdriver.PhantomJS()
client.get("http://foo")
soup = bs(client.page_source)

I would advice to start your own solution. You'll understand Scrapy's benefits doing so.

ps: take a look at scrapely: https://github.com/scrapy/scrapely

pps: take a look at Portia, to start extracting information visually, without programming knowledge: https://github.com/scrapinghub/portia

input_variable = input ("Enter your name: ")
print ("your name is" + input_variable)

You have to enter input in either single or double quotes

Ex:'dude' -> correct

    dude -> not correct

If you have enough memory, I've found some performance gains by reading the entire file into a memory stream, and then opening a stream reader on that to read the lines. As long as you actually plan on reading the whole file anyway, this can yield some improvements.

If you are doing something like writing HTML and Javascript in a code editor on your personal computer, and testing the output in your browser, you will probably get error messages about Cross Origin Requests. Your browser will render HTML and run Javascript, jQuery, angularJs in your browser without needing a server set up. But many web browsers are programed to watch for cross site attacks, and will block requests. You don't want just anyone being able to read your hard drive from your web browser. You can create a fully functioning web page using Notepad++ that will run Javascript, and frameworks like jQuery and angularJs; and test everything just by using the Notepad++ menu item, RUN, LAUNCH IN FIREFOX. That's a nice, easy way to start creating a web page, but when you start creating anything more than layout, css and simple page navigation, you need a local server set up on your machine.

Here are some options that I use.

1. Test your web page locally on Firefox, then deploy to your host.
2. or: Run a local server

Test on Firefox, Deploy to Host

1. Firefox currently allows Cross Origin Requests from files served from your hard drive
2. Your web hosting site will allow requests to files in folders as configured by the manifest file

Run a Local Server

• Run a server on your computer, like Apache or Python
• Python isn't a server, but it will run a simple server

Run a Local Server with Python

Get your IP address:

• On Windows: Open up the 'Command Prompt'. All Programs, Accessories, Command Prompt
• I always run the Command Prompt as Administrator. Right click the Command Prompt menu item and look for Run As Administrator
• Type the command: ipconfig and hit Enter.
• Look for: IPv4 Address . . . . . . . . 12.123.123.00
• There are websites that will also display your IP address

If you don't have Python, download and install it.

Using the 'Command Prompt' you must go to the folder where the files are that you want to serve as a webpage.

• If you need to get back to the C:\ Root directory - type cd/
• type cd Drive:\Folder\Folder\etc to get to the folder where your .Html file is (or php, etc)
• Check the path. type: path at the command prompt. You must see the path to the folder where python is located. For example, if python is in C:\Python27, then you must see that address in the paths that are listed.
• If the path to the Python directory is not in the path, you must set the path. type: help path and hit Enter. You will see help for path.
• Type something like: path c:\python27 %path%
• %path% keeps all your current paths. You don't want to wipe out all your current paths, just add a new path.
• Create the new path FROM the folder where you want to serve the files.
• Start the Python Server: Type: python -m SimpleHTTPServer port Where 'port' is the number of the port you want, for example python -m SimpleHTTPServer 1337
• If you leave the port empty, it defaults to port 8000
• If the Python server starts successfully, you will see a msg.

Run You Web Application Locally

• Open a browser
• In the address line type: http://your IP address:port
• http://xxx.xxx.x.x:1337 or http://xx.xxx.xxx.xx:8000 for the default
• If the server is working, you will see a list of your files in the browser
• Click the file you want to serve, and it should display.

More advanced solutions

• Install a code editor, web server, and other services that are integrated.

You can install Apache, PHP, Python, SQL, Debuggers etc. all separately on your machine, and then spend lots of time trying to figure out how to make them all work together, or look for a solution that combines all those things.

I like using XAMPP with NetBeans IDE. You can also install WAMP which provides a User Interface for managing and integrating Apache and other services.

When making a call such as a = foo();, the compiler might push the address of the result structure on the stack and passes it as a "hidden" pointer to the foo() function. Effectively, it could become something like:

void foo(MyObj *r) {
    struct MyObj a;
    // ...
    *r = a;
}

foo(&a);

However, the exact implementation of this is dependent on the compiler and/or platform. As Carl Norum notes, if the structure is small enough, it might even be passed back completely in a register.

I had similar problem after updating SDK from r20 to r21, but all I missed was the SDK/AVD Manager and running into this post while searching for the answer.

I managed to solve it by going to Window -> Customize Perspective, and under Command Groups Availability tab check the Android SDK and AVD Manager (not sure why it became unchecked because it was there before). I'm using Mac by the way, in case the menu option looks different.

Since none of you mentioned nothing about the const keyword...

The const keyword modifies the type of a type declaration or the type of a function parameter, preventing the value from varying. (Source: MS)

In other words: passing a parameter by reference exposes it to modification by the callee. Using the const keyword prevents the modification.

From http://docs.python-requests.org/en/latest/user/quickstart/

url = 'https://api.github.com/some/endpoint'
payload = {'some': 'data'}
headers = {'content-type': 'application/json'}

r = requests.post(url, data=json.dumps(payload), headers=headers)

You just need to create a dict with your headers (key: value pairs where the key is the name of the header and the value is, well, the value of the pair) and pass that dict to the headers parameter on the .get or .post method.

So more specific to your question:

headers = {'foobar': 'raboof'}
requests.get('http://himom.com', headers=headers)

Being au fait with patterns as defined by (say) the GOF book, and naming objects after these gets me a long way in naming classes, organising them and communicating intent. Most people will understand this nomenclature (or at least a major part of it).

When you start using ECMAScript 6 this error thrown by your IDE.

There are two options available:

if you have only one file and want to use the es6 then simply add below line at the top of the file.

/*jshint esversion: 6 */

Or if you have number of js file or you are using any framework(like nodejs express)you can create a new file named .jshintrc in your root directory and add code below in the file:

{
    "esversion": 6
}

If you want to use the es6 version onward for each project you can configure your IDE.

Alternatively you could use SciPy

from scipy import stats
stats.uniform(0.5, 13.3).rvs(50)

and for the record to sample integers it's

stats.randint(10, 20).rvs(50)

You can also do like this :

  $("#table-filters li").parent().find('li').removeClass("active");

You could also tell MySQL to execute the commands in the given file, like so:

mysql --user=root --password=sa casemanager < CaseManager.sql

You can also execute javascript using webdriver.

from selenium import webdriver

driver = webdriver.Firefox()
driver.get(url)
driver.execute_script('document.title')

or store the value in a variable

result = driver.execute_script('var text = document.title ; return var')

You can simply print it.

@a = qw(abc def hij);

print "@a";

You will got:

abc def hij
