Answer

/[\W\S_]/

Explanation

This creates a character class removing the word characters, space characters, and adding back the underscore character (as underscore is a "word" character). All that is left is the special characters. Capital letters represent the negation of their lowercase counterparts.

\W will select all non "word" characters equivalent to [^a-zA-Z0-9_]
\S will select all non "whitespace" characters equivalent to [ \t\n\r\f\v]
_ will select "_" because we negate it when using the \W and need to add it back in

You use something like

from flask import send_file

@app.route('/get_image')
def get_image():
    if request.args.get('type') == '1':
       filename = 'ok.gif'
    else:
       filename = 'error.gif'
    return send_file(filename, mimetype='image/gif')

to send back ok.gif or error.gif, depending on the type query parameter. See the documentation for the send_file function and the request object for more information.

I get the same error in WP when I use php ver 7.1.6 - just take your php version back to 7.0.20 and the error will disappear.

The problem is that dataTable is not defined at the point you are calling this method.

Ensure that you are loading the .js files in the correct order:

<script src="/Scripts/jquery.dataTables.js"></script>
<script src="/Scripts/dataTables.bootstrap.js"></script>

Solution-1: - If you want to search for a combination of characters or an independent word from a sentence.

String sentence = "In the Name of Allah, the Most Beneficent, the Most Merciful."
if (sentence.matches(".*Beneficent.*")) {return true;}
else{return false;}

Solution-2: - There is another possibility you want to search for an independent word from a sentence then Solution-1 will also return true if you searched a word exists in any other word. For example, If you will search cent from a sentence containing this word ** Beneficent** then Solution-1 will return true. For this remember to add space in your regular expression.

String sentence = "In the Name of Allah, the Most Beneficent, the Most Merciful."
if (sentence.matches(".* cent .*")) {return true;}
else{return false;}

Now in Solution-2 it wll return false because no independent cent word exist.

Additional: You can add or remove space on either side in 2nd solution according to your requirements.

Not able to comment because I just created this account, but I wanted to make sure to point out that @eggrobot78's solution works, but it is exclusive in dart so it doesn't include the last number. If you change the last line to "r = min + rnd.nextInt(max - min + 1);", then it should include the last number as well.

Explanation:

max = 5;
min = 3;
Random rnd = new Random();
r = min + rnd.nextInt(max - min);
//max - min is 2
//nextInt is exclusive so nextInt will return 0 through 1
//3 is added so the line will give a number between 3 and 4
//if you add the "+ 1" then it will return a number between 3 and 5

To answer your question, yes. The other have answered that part, but it also seems like you're asking if that's the best way to do it.

It would probably depend on what you are doing. Typically you would have a user click what items they want to buy (ordering for example). Then they would hit a buy or checkout button. Then the form would send off to a page and process the result. You could do all of that with a cookie but I would find it to be more difficult.

This isn't appropriate in all situations but you can conditionally return false inside the component itself if a certain criteria is or isn't met.

It doesn't unmount the component, but it removes all rendered content. This would only be bad, in my mind, if you have event listeners in the component that should be removed when the component is no longer needed.

import React, { Component } from 'react';

export default class MyComponent extends Component {
    constructor(props) {
        super(props);

        this.state = {
            hideComponent: false
        }
    }

    closeThis = () => {
        this.setState(prevState => ({
            hideComponent: !prevState.hideComponent
        })
    });

    render() {
        if (this.state.hideComponent === true) {return false;}

        return (
            <div className={`content`} onClick={() => this.closeThis}>
                YOUR CODE HERE
            </div>
        );
    }
}

Consider using abstract classes if any of these statements apply to your situation:

1. You want to share code among several closely related classes.
2. You expect that classes that extend your abstract class have many common methods or fields or require access modifiers other than public (such as protected and private).
3. You want to declare non-static or non-final fields. This enables you to define methods that can access and modify the state of the object to which they belong.

Consider using interfaces if any of these statements apply to your situation:

1. You expect that unrelated classes would implement your interface. For example, the interfaces Comparable and Cloneable are implemented by many unrelated classes.
2. You want to specify the behavior of a particular data type, but not concerned about who implements its behavior.
3. You want to take advantage of multiple inheritances.

Hmm yeah... what you're doing is absolutely wrong. When you say str.split("\r\n|\r|\n") it will try to find the exact string "\r\n|\r|\n". That's where you're wrong. There's no such occurance in the whole string. What you really want is what David Hedlund suggested:

lines = str.split(/\r\n|\r|\n/);
return lines.length;

The reason is that the split method doesn't convert strings into regular expressions in JavaScript. If you want to use a regexp, use a regexp.

If you just want the bitmap, This too works

InputStream inputStream = mContext.getContentResolver().openInputStream(uri);
Bitmap bmp = BitmapFactory.decodeStream(inputStream);
if( inputStream != null ) inputStream.close();

sample uri : content://media/external/images/media/12345

If you're already in conflicted state, and do not want to checkout path one by one. You may try

git merge --abort
git pull -X theirs

The answers already explain how attributes and properties are handled differently, but I really would like to point out how totally insane this is. Even if it is to some extent the spec.

It is crazy, to have some of the attributes (e.g. id, class, foo, bar) to retain only one kind of value in the DOM, while some attributes (e.g. checked, selected) to retain two values; that is, the value "when it was loaded" and the value of the "dynamic state". (Isn't the DOM supposed to be to represent the state of the document to its full extent?)

It is absolutely essential, that two input fields, e.g. a text and a checkbox behave the very same way. If the text input field does not retain a separate "when it was loaded" value and the "current, dynamic" value, why does the checkbox? If the checkbox does have two values for the checked attribute, why does it not have two for its class and id attributes? If you expect to change the value of a text *input* field, and you expect the DOM (i.e. the "serialized representation") to change, and reflect this change, why on earth would you not expect the same from an input field of type checkbox on the checked attribute?

The differentiation, of "it is a boolean attribute" just does not make any sense to me, or is, at least not a sufficient reason for this.

Did you try passwd -d root? Most likely, this will do what you want.

You can also manually edit /etc/shadow: (Create a backup copy. Be sure that you can log even if you mess up, for example from a rescue system.) Search for "root". Typically, the root entry looks similar to

root:$X$SK5xfLB1ZW:0:0...

There, delete the second field (everything between the first and second colon):

root::0:0...

Some systems will make you put an asterisk (*) in the password field instead of blank, where a blank field would allow no password (CentOS 8 for example)

root:*:0:0...

Save the file, and try logging in as root. It should skip the password prompt. (Like passwd -d, this is a "no password" solution. If you are really looking for a "blank password", that is "ask for a password, but accept if the user just presses Enter", look at the manpage of mkpasswd, and use mkpasswd to create the second field for the /etc/shadow.)

It means it's an array of wide characters (wchar_t) instead of narrow characters (char).

It's a just a string of a different kind of character, not necessarily a Unicode string.

Supervised Learning: You give variously labelled example data as input, along with the correct answers. This algorithm will learn from it, and start predicting correct results based on the inputs thereafter. Example: Email Spam filter

Unsupervised Learning: You just give data and don't tell anything - like labels or correct answers. Algorithm automatically analyses patterns in the data. Example: Google News

You are mixing the deprecated mysql extension with mysqli.

Try something like:

$sql = mysqli_query($success, "SELECT * FROM login WHERE username = '".$_POST['username']."' and password = '".md5($_POST['password'])."'");
$row = mysqli_num_rows($sql);

To expand on the above, you will need to get at the history object. If you are using BrowserRouter, you can import withRouter and wrap your component with a higher-order component (HoC) in order to have access via props to the history object's properties and functions.

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

const myComponent = ({ history }) => {

    history.listen((location, action) => {
        // location is an object like window.location
        console.log(action, location.pathname, location.state)
    });

    return <div>...</div>;
};

export default withRouter(myComponent);

The only thing to be aware of is that withRouter and most other ways to access the history seem to pollute the props as they de-structure the object into it.

It might be a bit late, but this does it:

set "case1=operation1"
set "case2=operation2"
set "case3=operation3"

setlocal EnableDelayedExpansion
!%switch%!
endlocal

%switch% gets replaced before line execution. Serious downsides:

• You override the case variables
• It needs DelayedExpansion

Might eventually be usefull in some cases.

Theory

There are two important points to consider:

1. Who creates objects

   • [Factory]: You have to write HOW object should be created. You have separate Factory class which contains creation logic.
   • [Dependency Injection]: In practical cases are done by external frameworks (for example in Java that would be spring/ejb/guice). Injection happens "magically" without explicite creation of new objects

2. What kind of objects it manages:

   • [Factory]: Usually responsible for creation of stateful objects
   • [Dependency Injections] More likely to create stateless objects

Practical example how to use both factory and dependency injection in single project

1. What we want to build

Application module for creating order which contains multiple entries called orderline.

2. Architecture

Let's assume we want to create following layer architecture:

Domain objects may be objects stored inside database. Repository (DAO) helps with retrievar of objects from database. Service provides API to other modules. Alows for operations on order module

3. Domain Layer and usage of factories

Entities which will be in the database are Order and OrderLine. Order can have multiple OrderLines.

Now comes important design part. Should modules outside this one create and manage OrderLines on their own? No. Order Line should exist only when you have Order associated with it. It would be best if you could hide internal implementaiton to outside classes.

But how to create Order without knowledge about OrderLines?

Factory

Someone who wants to create new order used OrderFactory (which will hide details about the fact how we create Order).

Thats how it will look inside IDE. Classes outside domain package will use OrderFactory instead of constructor inside Order

4. Dependency Injection Dependency injection is more commonly used with stateless layers such as repository and service.

OrderRepository and OrderService are managed by dependency injection framework. Repository is responsible for managing CRUD operations on database. Service injects Repository and uses it to save/find correct domain classes.

A tuple consists of a number of values separated by commas. like

>>> t = 12345, 54321, 'hello!'
>>> t[0]
12345

tuple are index based (and also immutable) in Python.

Here in this case x = rows[1][1] + " " + rows[1][2] have only two index 0, 1 available but you are trying to access the 3rd index.

not sure if you solved your question, but I found this worked to increment the row number upon dragging.

= INDIRECT("'"&$A$5&"'!$G"&7+B1)

Where B1 refers to an index number, starting at 0.

So if you copy-drag both the index cell and the cell with the indirect formula, you'll increment the indirect. You could probably create a more elegant counter with the Index function too.

Hope this helps.

Try PyPDF2.

C++ style casts are checked by the compiler. C style casts aren't and can fail at runtime.

Also, c++ style casts can be searched for easily, whereas it's really hard to search for c style casts.

Another big benefit is that the 4 different C++ style casts express the intent of the programmer more clearly.

When writing C++ I'd pretty much always use the C++ ones over the the C style.

New in django 1.7

you could use JsonResponse objects.

from the docs:

from django.http import JsonResponse
return JsonResponse({'foo':'bar'})

If you do not want to use the Array function.

public class GArray
{
    int[] mainArray;
    int index;
    int i = 0;

    public GArray()
    {
        index = 0;
        mainArray = new int[4];
    }
    public void add(int addValue)
    {

        if (index == mainArray.Length)
        {
            int newSize = index * 2;
            int[] temp = new int[newSize];
            for (int i = 0; i < mainArray.Length; i++)
            {
                temp[i] = mainArray[i];
            }
            mainArray = temp;
        }
        mainArray[index] = addValue;
        index++;

    }
    public void print()
    {
        for (int i = 0; i < index; i++)
        {
            Console.WriteLine(mainArray[i]);
        }
    }
 }
 class Program
{
    static void Main(string[] args)
    {
        GArray myArray = new GArray();
        myArray.add(1);
        myArray.add(2);
        myArray.add(3);
        myArray.add(4);
        myArray.add(5);
        myArray.add(6);
        myArray.print();
        Console.ReadKey();
    }
}

You should use PDO Prepare

From the link:

Calling PDO::prepare() and PDOStatement::execute() for statements that will be issued multiple times with different parameter values optimizes the performance of your application by allowing the driver to negotiate client and/or server side caching of the query plan and meta information, and helps to prevent SQL injection attacks by eliminating the need to manually quote the parameters.

You can simply check out a new branch, and then commit:

git checkout -b my_new_branch
git commit

Checking out the new branch will not discard your changes.

private static void getRepeatedNumbers() {

    int [] numArray = {2,5,3,8,1,2,8,3,3,1,5,7,8,12,134};
    Set<Integer> nums = new HashSet<Integer>();
    
    for (int i =0; i<numArray.length; i++) {
        if(nums.contains(numArray[i]))
            continue;
            int count =1;
            for (int j = i+1; j < numArray.length; j++) {
                if(numArray[i] == numArray[j]) {
                    count++;
                }
                    
            }
            System.out.println("The "+numArray[i]+ " is repeated "+count+" times.");
            nums.add(numArray[i]);
        }
    }
    

I do this to get the first and last value. This works with more values too.

$a = array(
    'foo' => 400,
    'bar' => 'xyz',
);
$first = current($a);   //400
$last = end($a);    //xyz

You can access the keys with ${!array[@]}:

bash-4.0$ echo "${!array[@]}"
foo bar

Then, iterating over the key/value pairs is easy:

for i in "${!array[@]}"
do
  echo "key :" $i
  echo "value:" ${array[$i]}
done

ServiceStack.Text has a T.Dump() extension method that does exactly this, recursively dumps all properties of any type in a nice readable format.

Example usage:

var model = new TestModel();
Console.WriteLine(model.Dump());

and output:

{
    Int: 1,
    String: One,
    DateTime: 2010-04-11,
    Guid: c050437f6fcd46be9b2d0806a0860b3e,
    EmptyIntList: [],
    IntList:
    [
        1,
        2,
        3
    ],
    StringList:
    [
        one,
        two,
        three
    ],
    StringIntMap:
    {
        a: 1,
        b: 2,
        c: 3
    }
}

If you are in an interactive environment like Jupyter or ipython you might be interested in clearing unwanted var's if they are getting heavy.

The magic-commands reset and reset_selective is vailable on interactive python sessions like ipython and Jupyter

1) reset

reset Resets the namespace by removing all names defined by the user, if called without arguments.

in and the out parameters specify whether you want to flush the in/out caches. The directory history is flushed with the dhist parameter.

reset in out

Another interesting one is array that only removes numpy Arrays:

reset array

2) reset_selective

Resets the namespace by removing names defined by the user. Input/Output history are left around in case you need them.

Clean Array Example:

In [1]: import numpy as np
In [2]: littleArray = np.array([1,2,3,4,5])
In [3]: who_ls
Out[3]: ['littleArray', 'np']
In [4]: reset_selective -f littleArray
In [5]: who_ls
Out[5]: ['np']

For SQL Server

select *
from YourTable
where DateCol between getdate() and dateadd(d, 90, getdate())

From the documentation:

list.insert(i, x)
Insert an item at a given position. The first argument is the index of the element before which to insert, so a.insert(0, x) inserts at the front of the list, and a.insert(len(a),x) is equivalent to a.append(x)

http://docs.python.org/2/tutorial/datastructures.html#more-on-lists

You can get value by using id for that element in onclick function

function dosomething(){
     var buttonValue = document.getElementById('buttonId').value;
}

You can't, Print Preview is a feature of a browser, and therefore should be protected from being called by JavaScript as it would be a security risk.

That's why your example uses Active X, which bypasses the JavaScript security issues.

So instead use the print stylesheet that you already should have and show it for media=screen,print instead of media=print.

Read Alist Apart: Going to Print for a good article on the subject of print stylesheets.

There’s also clang_complete which uses the clang compiler to provide code completion for C++ projects. There’s another question with troubleshooting hints for this plugin.

The plugin seems to work fairly well as long as the project compiles, but is prohibitively slow for large projects (since it attempts a full compilation to generate the tags list).

Alternatively, this

def simpleaxis(ax):
    ax.spines['top'].set_visible(False)
    ax.spines['right'].set_visible(False)
    ax.get_xaxis().tick_bottom()
    ax.get_yaxis().tick_left()

seems to achieve the same effect on an axis without losing rotated label support.

(Matplotlib 1.0.1; solution inspired by this).

Not a jQuery way but... Why don't use simpler way. Remove 'c' from following array

var a = ['a','b','c','d']
a.splice(a.indexOf('c'),1);
>["c"]
a
["a", "b", "d"]

You can also use: (Note to myself: Don’t modify objects you don’t own)

Array.prototype.remove = function(v) { this.splice(this.indexOf(v) == -1 ? this.length : this.indexOf(v), 1); }
var a = ['a','b','c'];
a.remove('c'); //value of "a" is now ['a','b']

Adding is simplera.push('c')

By using below code you can set multiple colors based on word.

NSMutableArray * array = [[NSMutableArray alloc] initWithObjects:@"1 ball",@"2 ball",@"3 ball",@"4 ball", nil];    
NSMutableAttributedString *attStr = [[NSMutableAttributedString alloc] init];

    NSMutableAttributedString * textstr = [[NSMutableAttributedString alloc] initWithString:[NSString stringWithFormat:@"%@ ,",str] attributes:@{NSForegroundColorAttributeName :[self getRandomColor]}];
     [attStr appendAttributedString:textstr];
  }
UILabel *lab = [[UILabel alloc] initWithFrame:CGRectMake(10, 300, 300, 30)];
lab.attributedText = attStr;
[self.view addSubview:lab];

-(UIColor *) getRandomColor
{
   CGFloat redcolor = arc4random() % 255 / 255.0;
   CGFloat greencolor = arc4random() % 255 / 255.0;
   CGFloat bluencolor = arc4random() % 255 / 255.0;
   return  [UIColor colorWithRed:redcolor green:greencolor blue:bluencolor alpha:1.0];
}

Java doesn't allow you to do that. You'll need to refer to one of the classes by its fully qualified name and only import the other one.

The differences are

1. Only in String class + operator is overloaded. We can concat two String object using + operator, but in the case of StringBuffer we can't.

2. String class is overriding toString(), equals(), hashCode() of Object class, but StringBuffer only overrides toString().

   String s1 = new String("abc");
   String s2 = new String("abc");
   System.out.println(s1.equals(s2));  // output true
   
   StringBuffer sb1 = new StringBuffer("abc");
   StringBuffer sb2 = new StringBuffer("abc");
   System.out.println(sb1.equals(sb2));  // output false
   

3. String class is both Serializable as well as Comparable, but StringBuffer is only Serializable.

   Set<StringBuffer> set = new TreeSet<StringBuffer>();
   set.add(sb1);
   set.add(sb2);
   System.out.println(set);  // gives ClassCastException because there is no Comparison mechanism
   

4. We can create a String object with and without new operator, but StringBuffer object can only be created using new operator.

5. String is immutable but StringBuffer is mutable.
6. StringBuffer is synchronized, whereas String ain't.
7. StringBuffer is having an in-built reverse() method, but String dosen't have it.

The snippet you're showing doesn't seem to be directly responsible for the error.

This is how you can CAUSE the error:

namespace MyNameSpace
{
   int i; <-- THIS NEEDS TO BE INSIDE THE CLASS

   class MyClass
   {
      ...
   }
}

If you don't immediately see what is "outside" the class, this may be due to misplaced or extra closing bracket(s) }.

Try this simple code.

1. Components side code: to get both body and header property. Here there's a token in body and Authorization in the header.

loginUser() {
    this.userService.loginTest(this.loginCred).
    subscribe(res => {
        let output1 = res;
        console.log(output1.body.token);
        console.log(output1.headers.get('Authorization'));
    })
}

2. Service side code: sending login data in the body and observe the response in Observable any which be subscribed in the component side.

loginTest(loginCred: LoginParams): Observable<any> {
    const header1= {'Content-Type':'application/json',};
    const body =  JSON.stringify(loginCred);
    return this.http.post<any>(this.baseURL+'signin',body,{
        headers: header1,
        observe: 'response',
        responseType: 'json'
    });
}

You need to download mysql-connector-java-5.1.46.tar.gz, not the latest version. The Driver class that Pentaho uses is not included in mysql-connector-java-8.xx.yy versions.

I assume that you haven't set the TableName property of the DataTable, for example via constructor:

var tbl = new DataTable("dtImage");

If you don't provide a name, it will be automatically created with "Table1", the next table will get "Table2" and so on.

Then the solution would be to provide the TableName and then check with Contains(nameOfTable).

To clarify it: You'll get an ArgumentException if that DataTable already belongs to the DataSet (the same reference). You'll get a DuplicateNameException if there's already a DataTable in the DataSet with the same name(not case-sensitive).

It can be understood like this:

var a= []; //creates a new empty array
var a= {}; //creates a new empty object

You can also understand that

var a = {}; is equivalent to var a= new Object();

Note:

You can use Arrays when you are bothered about the order of elements(of same type) in your collection else you can use objects. In objects the order is not guaranteed.

<a href="#" onClick="window.open('http://www.yahoo.com', '_blank')">test</a>

Easy as that.

Or without JS

<a href="http://yahoo.com" target="_blank">test</a>

You need to search the World from the top right search bar and delete the expired certificate. Make sure you selected Login and All items.

In essence its job is very similar to IEnumerable<T> - to represent a queryable data source - the difference being that the various LINQ methods (on Queryable) can be more specific, to build the query using Expression trees rather than delegates (which is what Enumerable uses).

The expression trees can be inspected by your chosen LINQ provider and turned into an actual query - although that is a black art in itself.

This is really down to the ElementType, Expression and Provider - but in reality you rarely need to care about this as a user. Only a LINQ implementer needs to know the gory details.

Re comments; I'm not quite sure what you want by way of example, but consider LINQ-to-SQL; the central object here is a DataContext, which represents our database-wrapper. This typically has a property per table (for example, Customers), and a table implements IQueryable<Customer>. But we don't use that much directly; consider:

using(var ctx = new MyDataContext()) {
    var qry = from cust in ctx.Customers
              where cust.Region == "North"
              select new { cust.Id, cust.Name };
    foreach(var row in qry) {
        Console.WriteLine("{0}: {1}", row.Id, row.Name);
    }
}

this becomes (by the C# compiler):

var qry = ctx.Customers.Where(cust => cust.Region == "North")
                .Select(cust => new { cust.Id, cust.Name });

which is again interpreted (by the C# compiler) as:

var qry = Queryable.Select(
              Queryable.Where(
                  ctx.Customers,
                  cust => cust.Region == "North"),
              cust => new { cust.Id, cust.Name });

Importantly, the static methods on Queryable take expression trees, which - rather than regular IL, get compiled to an object model. For example - just looking at the "Where", this gives us something comparable to:

var cust = Expression.Parameter(typeof(Customer), "cust");
var lambda = Expression.Lambda<Func<Customer,bool>>(
                  Expression.Equal(
                      Expression.Property(cust, "Region"),
                      Expression.Constant("North")
                  ), cust);

... Queryable.Where(ctx.Customers, lambda) ...

Didn't the compiler do a lot for us? This object model can be torn apart, inspected for what it means, and put back together again by the TSQL generator - giving something like:

 SELECT c.Id, c.Name
 FROM [dbo].[Customer] c
 WHERE c.Region = 'North'

(the string might end up as a parameter; I can't remember)

None of this would be possible if we had just used a delegate. And this is the point of Queryable / IQueryable<T>: it provides the entry-point for using expression trees.

All this is very complex, so it is a good job that the compiler makes it nice and easy for us.

For more information, look at "C# in Depth" or "LINQ in Action", both of which provide coverage of these topics.

What you can do is check whether you props is defined initially or not by checking if nextProps.blog.content is undefined or not since your body is nested inside it like

componentWillReceiveProps(nextProps) {

    if(nextProps.blog.content !== undefined && nextProps.blog.title !== undefined) {
       console.log("new title is", nextProps.blog.title);
       console.log("new body content is", nextProps.blog.content["body"]);
       this.setState({
           title: nextProps.blog.title,
           body: nextProps.blog.content["body"]
       })
    }
}

You need not use type to check for undefined, just the strict operator !== which compares the value by their type as well as value

In order to check for undefined, you can also use the typeof operator like

typeof nextProps.blog.content != "undefined"

Just use a onchnage Event for select box.

<select id="selectbox" name="" onchange="javascript:location.href = this.value;">
    <option value="https://www.yahoo.com/" selected>Option1</option>
    <option value="https://www.google.co.in/">Option2</option>
    <option value="https://www.gmail.com/">Option3</option>

</select>

And if selected option to be loaded at the page load then add some javascript code

<script type="text/javascript">
    window.onload = function(){
        location.href=document.getElementById("selectbox").value;
    }       
</script>

for jQuery: Remove the onchange event from <select> tag

jQuery(function () {
    // remove the below comment in case you need chnage on document ready
    // location.href=jQuery("#selectbox").val(); 
    jQuery("#selectbox").change(function () {
        location.href = jQuery(this).val();
    })
})

    function dropdownlist(listindex)
    {
         document.getElementById("ddlCity").options.length = 0;
         switch (listindex) 
         {
             case "Karnataka":
                     document.getElementById("ddlCity").options[0] = new Option("--select--", "");
                     document.getElementById("ddlCity").options[1] = new Option("Dharawad", "Dharawad");
                     document.getElementById("ddlCity").options[2] = new Option("Haveri", "Haveri");
                     document.getElementById("ddlCity").options[3] = new Option("Belgum", "Belgum");
                     document.getElementById("ddlCity").options[4] = new Option("Bijapur", "Bijapur");

                 break;

             case "Tamilnadu":
                 document.getElementById("ddlCity").options[0] = new Option("--select--", "");
                 document.getElementById("ddlCity").options[1] = new Option("dgdf", "dgdf");
                 document.getElementById("ddlCity").options[2] = new Option("gffd", "gffd");


                 break;
         }

    }

To find out if a path is a valid directory try:

file.info(cacheDir)[1,"isdir"]

file.info does not care about a slash on the end.

file.exists on Windows will fail for a directory if it ends in a slash, and succeeds without it. So this cannot be used to determine if a path is a directory.

file.exists("R:/data/CCAM/CCAMC160b_echam5_A2-ct-uf.-5t05N.190to240E_level1000/cache/")
[1] FALSE

file.exists("R:/data/CCAM/CCAMC160b_echam5_A2-ct-uf.-5t05N.190to240E_level1000/cache")
[1] TRUE

file.info(cacheDir)["isdir"]

Try this, it worked for me!

If you happen to have Eclipse not responding anymore sometimes, the reason could be that you sit on a 64bit machine where eclipse needs more memory. Be sure to have (at least) the following configurations in your eclipse.ini (I even use bigger values for the PermSizes):

-Xms512m
-Xmx1024m
-XX:PermSize=64m
-XX:MaxPermSize=128m

One thing bothering me with default parameters is that you can't specify the last parameters but use the default values for the first ones. For example, in your code, you can't create a Foo with no name but a given age (however, if I remember correctly, this will be possible in C++0x, with the unified constructing syntax). Sometimes, this makes sense, but it can also be really awkward.

In my opinion, there is no rule of thumb. Personnaly, I tend to use multiple overloaded constructors (or methods), except if only the last argument needs a default value.

This answer got me 90% of the way there. I found the rest of my answer on the Microsoft site here.

The code below is what I'm using to target all ie by adding a .ie class to <html>

Use jQuery (which deprecated .browser in favor of user agents in 1.9+, see http://api.jquery.com/jQuery.browser/) to add an .ie class:

// ie identifier
$(document).ready(function () {
  if (navigator.appName == 'Microsoft Internet Explorer') {
    $("html").addClass("ie");
  }
});

For example, you have a Button named as Button1. First click on it it will open the EventHandler of that Button2 to call another Form you should write the following code to your Button.

your name example=form2.

form2 obj=new form2();

obj.show();

To close form1, write the following code:

form1.visible=false; or form1.Hide();

Check the following example:

// First get your image
$imgPath = 'path-to-your-picture/image.jpg';
$img = base64_encode(file_get_contents($imgPath));
echo '<img width="100" height="100" src="data:image/jpg;base64,'. $img .'" />'

It could also mean that the current Java type system version isn't good enough for your case. There were several JSR propositions / hacks to fix this: Type tokens, Super Type Tokens, Class.cast().

If you really need this supression, narrow it down as much as possible (e.g. don't put it onto the class itself or onto a long method). An example:

public List<String> getALegacyListReversed() {
   @SuppressWarnings("unchecked") List<String> list =
       (List<String>)legacyLibrary.getStringList();

   Collections.reverse(list);
   return list;
}

You are getting this error because "origin" is not available. "origin" is a convention not part of the command. "origin" is the local name of the remote repository.

For example you could also write:

git remote add myorigin [email protected]:myname/oldrep.git  
git remote add testtest [email protected]:myname/oldrep.git

See the manual:

http://www.kernel.org/pub/software/scm/git/docs/git-remote.html

To remove a remote repository you enter:

git remote rm origin

Again "origin" is the name of the remote repository if you want to remove the "upstream" remote:

git remote rm upstream

Yea these are great if your using a simple ORM like Dapper.

If your using .Net you can generate an XSD file at run time with any DataSet using the WriteXmlSchema method. http://msdn.microsoft.com/en-us/library/xt7k72x8(v=vs.110).aspx

Like this:

using (SqlConnection cnn = new SqlConnection(mConnStr)) {
DataSet Data = new DataSet();
cnn.Open();
string sql = "SELECT * FROM Person";

using (SqlDataAdapter Da = new SqlDataAdapter(sql, cnn))
{
try
{
    Da.Fill(Data);
    Da.TableMappings.Add("Table", "Person");
    Data.WriteXmlSchema(@"C:\Person.xsd");
}
catch (Exception ex)
{ MessageBox.Show(ex.Message); }
}
cnn.Close();

From there you can use xsd.exe to create a class that's XML serializable from the Developer Command Prompt. http://msdn.microsoft.com/en-us/library/x6c1kb0s(v=vs.110).aspx

like this:

xsd C:\Person.xsd /classes /language:CS

There is an easy way. You can get your result in a single line.

String memberIdsModifiedForQuery = memberIds.toString().replace("[", "(").replace("]", ")");

To get complete idea check the code below

 public static void main(String[] args) {       
        List<Integer>memberIds=new ArrayList<Integer>();  //This contain member ids we want to process
        //adding some sample values for example
        memberIds.add(3); 
        memberIds.add(4);
        memberIds.add(2);
        String memberIdsModifiedForQuery = memberIds.toString().replace("[", "(").replace("]", ")"); //here you will get (3,4,5) That you can directly use in query
        System.out.println(memberIdsModifiedForQuery);
        String exampleQuery="select * from customer where customer.id in "+memberIdsModifiedForQuery+" ";
    }

you need to wrap your text inside div and float it left while wrapper div should have height, and I've also added line height for vertical alignment

<div style="border-bottom-width: 1px; border-bottom-style: solid; border-bottom-color: gray;height:30px;">
   <div style="float:left;line-height:30px;">Contact Details</div>

    <button type="button" class="edit_button" style="float: right;">My Button</button>

</div>

also js fiddle here =) http://jsfiddle.net/xQgSm/

Use immediate children selector >:

$('#tblOne > tbody  > tr')

Description: Selects all direct child elements specified by "child" of elements specified by "parent".

You can simply add show.legend=FALSE to geom to suppress the corresponding legend

I found @naota's solution useful, and extended it to use dates as well

//taken from StackOverflow:
//https://stackoverflow.com/questions/3880615/how-can-i-determine-whether-a-given-string-represents-a-date
function isDate(val) {
    var d = new Date(val);
    return !isNaN(d.valueOf());
}

var getVal = function(elm, n){
  var v = $(elm).children('td').eq(n).text().toUpperCase();
  if($.isNumeric(v)){
    v = parseFloat(v,10);
    return v;
  }
  if (isDate(v)) {
    v = new Date(v);
    return v;
  }
  return v;
}

Your function doesn't return anything, so that's why when you use it with the print statement you get None. So either just call your function like this:

leapyr(1900)

or modify your function to return a value (by using the return statement), which then would be printed by your print statement.

Note: This does not address any possible problems you have with your leap year computation, but ANSWERS YOUR SPECIFIC QUESTION as to why you are getting None as a result of your function call in conjunction with your print.

Explanation:

Some short examples regarding the above:

def add2(n1, n2):
    print 'the result is:', n1 + n2  # prints but uses no *return* statement

def add2_New(n1, n2):
    return n1 + n2    # returns the result to caller

Now when I call them:

print add2(10, 5)

this gives:

the result is: 15
None

The first line comes form the print statement inside of add2(). The None from the print statement when I call the function add2() which does not have a return statement, causing the None to be printed. Incidentally, if I had just called the add2() function simply with (note, no print statement):

add2()

I would have just gotten the output of the print statement the result is: 15 without the None (which looks like what you are trying to do).

Compare this with:

print add2_New(10, 5)

which gives:

15

In this case the result is computed in the function add2_New() and no print statement, and returned to the caller who then prints it in turn.

Here is an end to end solution I implemented for streaming Android microphone audio to a server for playback: Android AudioRecord to Server over UDP Playback Issues

If you're putting this in a string within a program, you may actually need to use four backslashes (because the string parser will remove two of them when "de-escaping" it for the string, and then the regex needs two for an escaped regex backslash).

For instance:

regex("\\\\")

is interpreted as...

regex("\\" [escaped backslash] followed by "\\" [escaped backslash])

is interpreted as...

regex(\\)

is interpreted as a regex that matches a single backslash.

Depending on the language, you might be able to use a different form of quoting that doesn't parse escape sequences to avoid having to use as many - for instance, in Python:

re.compile(r'\\')

The r in front of the quotes makes it a raw string which doesn't parse backslash escapes.

u can use this code

var imageView = UIImageView(image: UIImage(name:"imageName"));
imageView.frame = CGrectMake(x,y imageView.frame.width*0.2,50);

or

var imageView = UIImageView(frame:CGrectMake(x,y, self.view.frame.size.width *0.2, 50)

The questions is perfectly valid and clear since Spinner and ComboBox (read it: Spinner where you can provide a custom value as well) are two different things.

I was looking for the same thing myself and I wasn't satisfied with the given answers. So I created my own thing. Perhaps some will find the following hints useful. I am not providing the full source code as I am using some legacy calls in my own project. It should be pretty clear anyway.

Here is the screenshot of the final thing:

The first thing was to create a view that will look the same as the spinner that hasn't been expanded yet. In the screenshot, on the top of the screen (out of focus) you can see the spinner and the custom view right bellow it. For that purpose I used LinearLayout (actually, I inherited from Linear Layout) with style="?android:attr/spinnerStyle". LinearLayout contains TextView with style="?android:attr/spinnerItemStyle". Complete XML snippet would be:

<com.example.comboboxtest.ComboBox 
    style="?android:attr/spinnerStyle"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    >

    <TextView
        android:id="@+id/textView"
        style="?android:attr/spinnerItemStyle"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:ellipsize="marquee"
        android:singleLine="true"
        android:text="January"
        android:textAlignment="inherit" 
    />

</com.example.comboboxtest.ComboBox>

As, I mentioned earlier ComboBox inherits from LinearLayout. It also implements OnClickListener which creates a dialog with a custom view inflated from the XML file. Here is the inflated view:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" 
    >
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal" 
        >
        <EditText
            android:id="@+id/editText"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:ems="10"
            android:hint="Enter custom value ..." >

            <requestFocus />
        </EditText>

        <Button
            android:id="@+id/button"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="OK" 
        />
    </LinearLayout>

    <ListView
        android:id="@+id/listView1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" 
    />

</LinearLayout>

There are two more listeners that you need to implement: onItemClick for the list and onClick for the button. Both of these set the selected value and dismiss the dialog.

For the list, you want it to look the same as expanded Spinner, you can do that providing the list adapter with the appropriate (Spinner) style like this:

ArrayAdapter<String> adapter = 
    new ArrayAdapter<String>(
        activity,
        android.R.layout.simple_spinner_dropdown_item, 
        states
    );

More or less, that should be it.

Try adding below code in build.gradle, it worked for me -

compileSdkVersion 23
buildToolsVersion '23.0.1'
defaultConfig {

1. Omit the viewport <meta> mentioned in the CSS docs
2. Override the width on the .container for each grid tier with a single width, for example width: 970px !important; Be sure that this comes after the default Bootstrap CSS. You can optionally avoid the !important with media queries or some selector-fu.
3. If using navbars, remove all navbar collapsing and expanding behavior.
4. For grid layouts, use .col-xs-* classes in addition to, or in place of, the medium/large ones. Don't worry, the extra-small device grid scales to all resolutions.

I noticed that Eemuli said that you can't change the log level after they are created - and while that might be the design, it isn't entirely true.

I ran into a situation where I was using a library that logged to slf4j - and I was using the library while writing a maven mojo plugin.

Maven uses a (hacked) version of the slf4j SimpleLogger, and I was unable to get my plugin code to reroute its logging to something like log4j, which I could control.

And I can't change the maven logging config.

So, to quiet down some noisy info messages, I found I could use reflection like this, to futz with the SimpleLogger at runtime.

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.slf4j.spi.LocationAwareLogger;
    try
    {
        Logger l = LoggerFactory.getLogger("full.classname.of.noisy.logger");  //This is actually a MavenSimpleLogger, but due to various classloader issues, can't work with the directly.
        Field f = l.getClass().getSuperclass().getDeclaredField("currentLogLevel");
        f.setAccessible(true);
        f.set(l, LocationAwareLogger.WARN_INT);
    }
    catch (Exception e)
    {
        getLog().warn("Failed to reset the log level of " + loggerName + ", it will continue being noisy.", e);
    }

Of course, note, this isn't a very stable / reliable solution... as it will break the next time the maven folks change their logger.

Well, the shortest way I know of, is following:

psql -U {user_name} -d {database_name} -f {file_path} -h {host_name}

database_name: Which database should you insert your file data in.

file_path: Absolute path to the file through which you want to perform the importing.

host_name: The name of the host. For development purposes, it is mostly localhost.

Upon entering this command in console, you will be prompted to enter your password.

I meet the same problem, @progrAmmar enlightened me, "took a closer look at the user table in mysql database".

My problem is not ssl_type, instead of the first field:Host. I changed the value by using

update user set Host='localhost' where User='root' and Host='%';

in mysqld_safe --skip-grant-tables model.

Then it works well.

I did a project on this. You can look at my github repo:

https://github.com/nishant-boro/django-rest-framework-download-expert

This module provides a simple way to serve files for download in django rest framework using Apache module Xsendfile. It also has an additional feature of serving downloads only to users belonging to a particular group

In vb.net you can actually compare strings with =. Even though String is a reference type, in vb.net = on String has been redefined to do a case-sensitive comparison of contents of the two strings.

You can test this with the following code. Note that I have taken one of the values from user input to ensure that the compiler cannot use the same reference for the two variables like the Java compiler would if variables were defined from the same string Literal. Run the program, type "This" and press <Enter>.

Sub Main()
    Dim a As String = New String("This")
    Dim b As String

    b = Console.ReadLine()

    If a = b Then
        Console.WriteLine("They are equal")
    Else
        Console.WriteLine("Not equal")
    End If
    Console.ReadLine()
End Sub

There is a scala way (if you have a enough memory on working machine):

val arr = df.select("column").rdd.collect
println(arr(100))

If dataframe schema is unknown, and you know actual type of "column" field (for example double), than you can get arr as following:

val arr = df.select($"column".cast("Double")).as[Double].rdd.collect

This will work for the non-US date format (dd/MM/yyyy):

set backupFilename=%DATE:~6,4%%DATE:~3,2%%DATE:~0,2%
7z a QuickBackup%backupFilename%.zip *.backup

Things have changed a lot in the last 7 years, we have native web components in most browsers now. IMO the core of the problem is sharing state between elements, once you have that its trivial to update the ui when state changes and vice versa.

To share data between elements you can create a StateObserver class, and extend your web components from that. A minimal implementation looks something like this:

// create a base class to handle state_x000D_
class StateObserver extends HTMLElement {_x000D_
 constructor () {_x000D_
   super()_x000D_
    StateObserver.instances.push(this)_x000D_
  }_x000D_
 stateUpdate (update) {_x000D_
   StateObserver.lastState = StateObserver.state_x000D_
    StateObserver.state = update_x000D_
    StateObserver.instances.forEach((i) => {_x000D_
     if (!i.onStateUpdate) return_x000D_
     i.onStateUpdate(update, StateObserver.lastState)_x000D_
    })_x000D_
  }_x000D_
}_x000D_
_x000D_
StateObserver.instances = []_x000D_
StateObserver.state = {}_x000D_
StateObserver.lastState = {}_x000D_
_x000D_
// create a web component which will react to state changes_x000D_
class CustomReactive extends StateObserver {_x000D_
 onStateUpdate (state, lastState) {_x000D_
   if (state.someProp === lastState.someProp) return_x000D_
    this.innerHTML = `input is: ${state.someProp}`_x000D_
  }_x000D_
}_x000D_
customElements.define('custom-reactive', CustomReactive)_x000D_
_x000D_
class CustomObserved extends StateObserver {_x000D_
 connectedCallback () {_x000D_
   this.querySelector('input').addEventListener('input', (e) => {_x000D_
     this.stateUpdate({ someProp: e.target.value })_x000D_
    })_x000D_
  }_x000D_
}_x000D_
customElements.define('custom-observed', CustomObserved)

<custom-observed>_x000D_
  <input>_x000D_
</custom-observed>_x000D_
<br />_x000D_
<custom-reactive></custom-reactive>

I like this approach because:

• no dom traversal to find data- properties
• no Object.observe (deprecated)
• no Proxy (which provides a hook but no communication mechanism anyway)
• no dependencies, (other than a polyfill depending on your target browsers)
• it's reasonably centralised & modular... describing state in html, and having listeners everywhere would get messy very quickly.
• it's extensible. This basic implementation is 20 lines of code, but you could easily build up some convenience, immutability, and state shape magic to make it easier to work with.

This explicitly prints 0 if installed else 1 using only awk:

dpkg-query -W -f '${Status}\n' 'PKG' 2>&1|awk '/ok installed/{print 0;exit}{print 1}'

or if you prefer the other way around where 1 means installed and 0 otherwise:

dpkg-query -W -f '${Status}\n' 'PKG' 2>&1|awk '/ok installed/{print 1;exit}{print 0}'

** replace PKG with your package name

Convenience function:

installed() {
    return $(dpkg-query -W -f '${Status}\n' "${1}" 2>&1|awk '/ok installed/{print 0;exit}{print 1}')
}

Did you try

$(this).val('test');

instead of

$(this).attr('value', 'test');

val() is generally easier, since the attribute you need to change may be different on different DOM elements.

You should not use available(). It gives no guarantees what so ever. From the API docs of available():

Returns an estimate of the number of bytes that can be read (or skipped over) from this input stream without blocking by the next invocation of a method for this input stream.

You would probably want to use something like

try {
    BufferedReader in = new BufferedReader(new FileReader("infilename"));
    String str;
    while ((str = in.readLine()) != null)
        process(str);
    in.close();
} catch (IOException e) {
}

(taken from http://www.exampledepot.com/egs/java.io/ReadLinesFromFile.html)

You get this error when declaring a forward reference inside the wrong namespace thus declaring a new type without defining it. For example:

namespace X
{
  namespace Y
  {
    class A;

    void func(A* a) { ... } // incomplete type here!
  }
}

...but, in class A was defined like this:

namespace X
{
  class A { ... };
}

Thus, A was defined as X::A, but I was using it as X::Y::A.

The fix obviously is to move the forward reference to its proper place like so:

namespace X
{
  class A;
  namespace Y
  {
    void func(X::A* a) { ... } // Now accurately referencing the class`enter code here`
  }
}

The approach I suggest works like the following. First, you create a basic datetime object from a mysql-formatted string; and then you format it the way you like. Luckily, mysql datetime is ISO8601-compliant, so the code itself could look quite simple and elegant. Keep in mind though that datetime column doesn't have a timezone information, so you need to convert it appropriately.

Here's the code:

(new ISO8601Formatted(
    new FromISO8601('2038-01-19 11:14:07'),
    'm/d/Y h:iA'
))
    ->value();

It outputs 01/19/2038 11:14AM -- hopefully what you expect.

This example uses meringue library. You can check out some more of it if you fancy.

Instead of hard-coding your app constants and doing a switch on the environment (I'll explain how to do that in a moment), I suggest using the twelve factor suggestion of having your build process define your BASE_URL and your API_KEY.

To answer how to expose your environment to react-native, I suggest using Babel's babel-plugin-transform-inline-environment-variables.

To get this working you need to download the plugin and then you will need to setup a .babelrc and it should look something like this:

{
  "presets": ["react-native"],
  "plugins": [
    "transform-inline-environment-variables"
  ]
}

And so if you transpile your react-native code by running API_KEY=my-app-id react-native bundle (or start, run-ios, or run-android) then all you have to do is have your code look like this:

const apiKey = process.env['API_KEY'];

And then Babel will replace that with:

const apiKey = 'my-app-id';

Hope this helps!

I've had this issue especially when entities are mashalled by Jaxb + Jax-rs. I've used the pre-fetch strategy, but I have also found it effective to provide two entities:

1. Full-blown entity with all collections mapped as EAGER
2. Simplified entity with most or all collections trimmed out

Common fields and be mapped in @MappedSuperclass and extended by both entity implementations.

Certainly if you always need the collections loaded, then there is no reason to not to EAGER load them. In my case I wanted a stripped down version of the entity to display in a grid.

Its very simple if you use <MediaElement>:

<MediaElement  Height="113" HorizontalAlignment="Left" Margin="12,12,0,0" 
Name="mediaElement1" VerticalAlignment="Top" Width="198" Source="C:\Users\abc.gif"
LoadedBehavior="Play" Stretch="Fill" SpeedRatio="1" IsMuted="False" />

Since it's an external resource you'd need to go with JSONP because of the Same origin policy.
To do that you need to add the querystring parameter callback:

$.getJSON("http://myjsonsource?callback=?", function(data) {
    // Get the element with id summary and set the inner text to the result.
    $('#summary').text(data.result);
});

You'll need to clear out your cache to have it completely wiped. this help page from git will help you out. (it helped me) http://help.github.com/remove-sensitive-data/

Where possible, I prefer to call the function rather than dispatch an event. This works well if you have control over the code you want to run, but see below for cases where you don't own the code.

window.onresize = doALoadOfStuff;

function doALoadOfStuff() {
    //do a load of stuff
}

In this example, you can call the doALoadOfStuff function without dispatching an event.

In your modern browsers, you can trigger the event using:

window.dispatchEvent(new Event('resize'));

This doesn't work in Internet Explorer, where you'll have to do the longhand:

var resizeEvent = window.document.createEvent('UIEvents'); 
resizeEvent.initUIEvent('resize', true, false, window, 0); 
window.dispatchEvent(resizeEvent);

jQuery has the trigger method, which works like this:

$(window).trigger('resize');

And has the caveat:

Although .trigger() simulates an event activation, complete with a synthesized event object, it does not perfectly replicate a naturally-occurring event.

You can also simulate events on a specific element...

function simulateClick(id) {
  var event = new MouseEvent('click', {
    'view': window,
    'bubbles': true,
    'cancelable': true
  });

  var elem = document.getElementById(id); 

  return elem.dispatchEvent(event);
}

SELECT SUM(No), HOUR(dateofissue) 
FROM tablename 
WHERE dateofissue>='2011-07-30' 
GROUP BY HOUR(dateofissue)

It will give the hour by sum from a particular day!

Using session, I successfully passed a parameter (name) from servlet #1 to servlet #2, using response.sendRedirect in servlet #1. Servlet #1 code:

protected void doPost(HttpServletRequest request, HttpServletResponse response) {
    String name = request.getParameter("name");
    String password = request.getParameter("password");
    ...
    request.getSession().setAttribute("name", name);
    response.sendRedirect("/todo.do");

In Servlet #2, you don't need to get name back. It's already connected to the session. You could do String name = (String) request.getSession().getAttribute("name"); ---but you don't need this.

If Servlet #2 calls a JSP, you can show name this way on the JSP webpage:

<h1>Welcome ${name}</h1>

Here's a version of batty's answer, but this computes the correct inverse. batty's version computes the transpose of the inverse.

// computes the inverse of a matrix m
double det = m(0, 0) * (m(1, 1) * m(2, 2) - m(2, 1) * m(1, 2)) -
             m(0, 1) * (m(1, 0) * m(2, 2) - m(1, 2) * m(2, 0)) +
             m(0, 2) * (m(1, 0) * m(2, 1) - m(1, 1) * m(2, 0));

double invdet = 1 / det;

Matrix33d minv; // inverse of matrix m
minv(0, 0) = (m(1, 1) * m(2, 2) - m(2, 1) * m(1, 2)) * invdet;
minv(0, 1) = (m(0, 2) * m(2, 1) - m(0, 1) * m(2, 2)) * invdet;
minv(0, 2) = (m(0, 1) * m(1, 2) - m(0, 2) * m(1, 1)) * invdet;
minv(1, 0) = (m(1, 2) * m(2, 0) - m(1, 0) * m(2, 2)) * invdet;
minv(1, 1) = (m(0, 0) * m(2, 2) - m(0, 2) * m(2, 0)) * invdet;
minv(1, 2) = (m(1, 0) * m(0, 2) - m(0, 0) * m(1, 2)) * invdet;
minv(2, 0) = (m(1, 0) * m(2, 1) - m(2, 0) * m(1, 1)) * invdet;
minv(2, 1) = (m(2, 0) * m(0, 1) - m(0, 0) * m(2, 1)) * invdet;
minv(2, 2) = (m(0, 0) * m(1, 1) - m(1, 0) * m(0, 1)) * invdet;

It forces the browser to use hardware acceleration to access the device’s graphical processing unit (GPU) to make pixels fly. Web applications, on the other hand, run in the context of the browser, which lets the software do most (if not all) of the rendering, resulting in less horsepower for transitions. But the Web has been catching up, and most browser vendors now provide graphical hardware acceleration by means of particular CSS rules.

Using -webkit-transform: translate3d(0,0,0); will kick the GPU into action for the CSS transitions, making them smoother (higher FPS).

Note: translate3d(0,0,0) does nothing in terms of what you see. It moves the object by 0px in x,y and z axis. It's only a technique to force the hardware acceleration.

Good read here: http://www.smashingmagazine.com/2012/06/21/play-with-hardware-accelerated-css/

When you say $(document).ready(f), you tell script engine to do the following:

1. get the object document and push it, since it's not in local scope, it must do a hash table lookup to find where document is, fortunately document is globally bound so it is a single lookup.
2. find the object $ and select it, since it's not in local scope, it must do a hash table lookup, which may or may not have collisions.
3. find the object f in global scope, which is another hash table lookup, or push function object and initialize it.
4. call ready of selected object, which involves another hash table lookup into the selected object to find the method and invoke it.
5. done.

In the best case, this is 2 hash table lookups, but that's ignoring the heavy work done by jQuery, where $ is the kitchen sink of all possible inputs to jQuery, so another map is likely there to dispatch the query to correct handler.

Alternatively, you could do this:

window.onload = function() {...}

which will

1. find the object window in global scope, if the JavaScript is optimized, it will know that since window isn't changed, it has already the selected object, so nothing needs to be done.
2. function object is pushed on the operand stack.
3. check if onload is a property or not by doing a hash table lookup, since it is, it is called like a function.

In the best case, this costs a single hash table lookup, which is necessary because onload must be fetched.

Ideally, jQuery would compile their queries to strings that can be pasted to do what you wanted jQuery to do but without the runtime dispatching of jQuery. This way you have an option of either

1. do dynamic dispatch of jquery like we do today.
2. have jQuery compile your query to pure JavaScript string that can be passed to eval to do what you want.
3. copy the result of 2 directly into your code, and skip the cost of eval.

If I can throw my hat into the ring, I think there is a cleaner way than the existing answers to reuse the radio button functionality.

Let's say you have the following property in your ViewModel:

Public Class ViewModel
    <Display(Name:="Do you like Cats?")>
    Public Property LikesCats As Boolean
End Class

You can expose that property through a reusable editor template:

First, create the file Views/Shared/EditorTemplates/YesNoRadio.vbhtml

Then add the following code to YesNoRadio.vbhtml:

@ModelType Boolean?

<fieldset>
    <legend>
        @Html.LabelFor(Function(model) model)
    </legend>

    <label>
        @Html.RadioButtonFor(Function(model) model, True) Yes
    </label>
    <label>
        @Html.RadioButtonFor(Function(model) model, False) No
    </label>
</fieldset>

You can call the editor for the property by manually specifying the template name in your View:

@Html.EditorFor(Function(model) model.LikesCats, "YesNoRadio")

Pros:

• Get to write HTML in an HTML editor instead of appending strings in code behind.
• Preserves the DisplayName DataAnnotation
• Allows clicks on Label to toggle radio button
• Least possible code to maintain in form (1 line). If something is wrong with the way it is rending, take it up with the template.

Simply create a function like this

  function methodName(params) {
    //the thing  you wanna do
  }

and call it in the place you need

 <Icon onClick = {() => { methodName(theParamsYouwantToPass);} }/>

I assume that you're writing to the file, then close it (so the user can open it in Excel), and then, before re-opening it for append/write operations, you want to check that the file isn't still open in Excel?

This is how you could do that:

while True:   # repeat until the try statement succeeds
    try:
        myfile = open("myfile.csv", "r+") # or "a+", whatever you need
        break                             # exit the loop
    except IOError:
        input("Could not open file! Please close Excel. Press Enter to retry.")
        # restart the loop

with myfile:
    do_stuff()

you can use

import matplotlib
matplotlib.use('agg')
import matplotlib.pyplot as plt

if you dont want to use tkinter at all.

Also dont forget to use %matplotlib inline at the top of your notebook if using one.

EDIT: agg is a different backend like tkinter for matplotlib.

For Uppercase CTRL + K + U

For Lowercase CTRL + K + L

An easy fix, which worked for me, is moving my files out of src and into the main folder of the project. It's not the best solution, but depending on the magnitude of the project and your time, it might be just perfect.

Try this:

AdditionalMatchers.aryEq(array);

If you know you will want a 'c' key, but do not know the value, insert 'c' with a dummy value when you create the dict.

d1 = OrderedDict([('c', None), ('a', '1'), ('b', '2')])

and change the value later.

d1['c'] = 3

According to the packages list in Ubuntu Wily Xenial Bionic there is a package named openjfx. This should be a candidate for what you're looking for:

JavaFX/OpenJFX 8 - Rich client application platform for Java

You can install it via:

sudo apt-get install openjfx

It provides the following JAR files to the OpenJDK installation on Ubuntu systems:

/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/ext/jfxrt.jar
/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/jfxswt.jar
/usr/lib/jvm/java-8-openjdk-amd64/lib/ant-javafx.jar
/usr/lib/jvm/java-8-openjdk-amd64/lib/javafx-mx.jar

If you want to have sources available, for example for debugging, you can additionally install:

sudo apt-get install openjfx-source

In case you are using quite popular in Spring Boot environment Kubernetes (K8S) or OpenShift, there's a possibility to store and retrieve application properties on runtime. This technique called secrets. In your configuration yaml file for Kubernetes or OpenShift you declare variable and placeholder for it, and on K8S\OpenShift side declare actual value which corresponds to this placeholder. For implementation details, see: K8S: https://kubernetes.io/docs/concepts/configuration/secret/ OpenShift: https://docs.openshift.com/container-platform/3.11/dev_guide/secrets.html

Just:

    document.getElementById('myDiv').innerHTMl += "New Content";

What happens if I promote the column to be a/the PK, too (a.k.a. identifying relationship)? As the column is now the PK, I must tag it with @Id (...).

This enhanced support of derived identifiers is actually part of the new stuff in JPA 2.0 (see the section 2.4.1 Primary Keys Corresponding to Derived Identities in the JPA 2.0 specification), JPA 1.0 doesn't allow Id on a OneToOne or ManyToOne. With JPA 1.0, you'd have to use PrimaryKeyJoinColumn and also define a Basic Id mapping for the foreign key column.

Now the question is: are @Id + @JoinColumn the same as just @PrimaryKeyJoinColumn?

You can obtain a similar result but using an Id on OneToOne or ManyToOne is much simpler and is the preferred way to map derived identifiers with JPA 2.0. PrimaryKeyJoinColumn might still be used in a JOINED inheritance strategy. Below the relevant section from the JPA 2.0 specification:

11.1.40 PrimaryKeyJoinColumn Annotation

The PrimaryKeyJoinColumn annotation specifies a primary key column that is used as a foreign key to join to another table.

The PrimaryKeyJoinColumn annotation is used to join the primary table of an entity subclass in the JOINED mapping strategy to the primary table of its superclass; it is used within a SecondaryTable annotation to join a secondary table to a primary table; and it may be used in a OneToOne mapping in which the primary key of the referencing entity is used as a foreign key to the referenced entity^[108].

...

If no PrimaryKeyJoinColumn annotation is specified for a subclass in the JOINED mapping strategy, the foreign key columns are assumed to have the same names as the primary key columns of the primary table of the superclass.

...

Example: Customer and ValuedCustomer subclass

@Entity
@Table(name="CUST")
@Inheritance(strategy=JOINED)
@DiscriminatorValue("CUST")
public class Customer { ... }

@Entity
@Table(name="VCUST")
@DiscriminatorValue("VCUST")
@PrimaryKeyJoinColumn(name="CUST_ID")
public class ValuedCustomer extends Customer { ... }

_{[108] The derived id mechanisms described in section 2.4.1.1 are now to be preferred over PrimaryKeyJoinColumn for the OneToOne mapping case.}

This source http://weblogs.java.net/blog/felipegaucho/archive/2009/10/24/jpa-join-table-additional-state states that using @ManyToOne and @Id works with JPA 1.x. Who's correct now?

The author is using a pre release JPA 2.0 compliant version of EclipseLink (version 2.0.0-M7 at the time of the article) to write an article about JPA 1.0(!). This article is misleading, the author is using something that is NOT part of JPA 1.0.

For the record, support of Id on OneToOne and ManyToOne has been added in EclipseLink 1.1 (see this message from James Sutherland, EclipseLink comitter and main contributor of the Java Persistence wiki book). But let me insist, this is NOT part of JPA 1.0.

You have a constructor which takes 2 parameters. You should write something like:

new ErrorEventArg(errorMsv, lastQuery)

It's less code and easier to read.

EDIT

Or, in order for your way to work, you can try writing a default constructor for ErrorEventArg which would have no parameters, like this:

public ErrorEventArg() {}

Rather than re-explaining, I will link to this rather extensive & highly rated question/answer:

Vertically align text to top within a UILabel

The short answer is no, Apple didn't make this easy, but it is possible by changing the frame size.

shift column gdp up:

df.gdp = df.gdp.shift(-1)

and then remove the last row

Try to run php over fcgid, this may help:

These are the classic errors you will see when running PHP as an Apache module. We struggled with these errors for months. Switching to using PHP via mod_fcgid (as James recommends) will fix all of these problems. Be sure you have the latest Visual C++ Redistributable package installed:

http://support.microsoft.com/kb/2019667

Also, I recommend switching to the 64-bit version of MySQL. No real reason to run the 32-bit version anymore.

Static Polymorphism: is where the decision to resolve which method to accomplish, is determined during the compile time. Method Overloading could be an example of this.

Dynamic Polymorphism: is where the decision to choose which method to execute, is set during the run-time. Method Overriding could be an example of this.

In my case for exact same error, I was also not the only developer.

So I went to commit & push my changes at same time, seen at bottom of the Commit dialog popup:

...but I made the huge mistake of forgetting to hit the Fetch button to see if I have latest, which I did not.

The commit successfully executed, however not the push, but instead gives the same mentioned error; ...even though other developers didn't alter same files as me, I cannot pull latest as same error is presented.

The GUI Solution

Most of the time I prefer sticking with Sourcetree's GUI (Graphical User Interface). This solution might not be ideal, however this is what got things going again for me without worrying that I may lose my changes or compromise more recent updates from other developers.

STEP 1

Right-click on the commit right before yours to undo your locally committed changes and select Reset current branch to this commit like so:

STEP 2

Once all the loading spinners disappear and Sourcetree is done loading the previous commit, at the top-left of window, click on Pull button...

...then a dialog popup will appear, and click the OK button at bottom-right:

STEP 3

After pulling latest, if you do not get any errors, skip to STEP 4 (next step below). Otherwise if you discover any merge conflicts at this point, like I did with my Web.config file:

...then click on the Stash button at the top, a dialog popup will appear and you will need to write a Descriptive-name-of-your-changes, then click the OK button:

...once Sourcetree is done stashing your altered file(s), repeat actions in STEP 2 (previous step above), and then your local files will have latest changes. Now your changes can be reapplied by opening your STASHES seen at bottom of Sourcetree left column, use the arrow to expand your stashes, then right-click to choose Apply Stash 'Descriptive-name-of-your-changes', and after select OK button in dialog popup that appears:

IF you have any Merge Conflict(s) right now, go to your preferred text-editor, like Visual Studio Code, and in the affected files select the Accept Incoming Change link, then save:

Then back to Sourcetree, click on the Commit button at top:

then right-click on the conflicted file(s), and under Resolve Conflicts select the Mark Resolved option:

STEP 4

Finally!!! We are now able to commit our file(s), also checkmark the Push changes immediately to origin option before clicking the Commit button:

P.S. while writing this, a commit was submitted by another developer right before I got to commit, so had to pretty much repeat steps.

Here is the changes you need to be done

just replace the carousel div with the below code

You have missed the '#' for data-target and add active class for the first item

<div id="carousel" class="carousel slide" data-ride="carousel">
            <ol class="carousel-indicators">
                <li data-target="#carousel" data-slide-to="0"></li>
                <li data-target="#carousel" data-slide-to="1"></li>
                <li data-target="#carousel" data-slide-to="2"></li>
            </ol>
            <div class="carousel-inner">
                <div class="item active">
                    <img src="img/slide_1.png" alt="Slide 1">
                </div>
                <div class="item">

            <a href="#carousel" class="left carousel-control" data-slide="prev">
                <span class="glyphicon glyphicon-chevron-left"></span>
            </a>
            <a href="#carousel" class="right carousel-control" data-slide="next">
                <span class="glyphicon glyphicon-chevron-right"></span>

Try itext. Add dependency to your build.gradle for latest as of this post

Note: special version for android, trailing "g":

dependencies {
    compile 'com.itextpdf:itextg:5.5.9'
}

try

CREATE TABLE [dbo].[Names]
(
    [Name] [nvarchar](64) NOT NULL,
    [CreateTS] [smalldatetime] NOT NULL CONSTRAINT CreateTS_DF DEFAULT CURRENT_TIMESTAMP,
    [UpdateTS] [smalldatetime] NOT NULL

)

PS I think a smalldatetime is good enough. You may decide differently.

Can you not do this at the "moment of impact" ?

In Sql Server, this is common:

Update dbo.MyTable 
Set 

ColA = @SomeValue , 
UpdateDS = CURRENT_TIMESTAMP
Where...........

Sql Server has a "timestamp" datatype.

But it may not be what you think.

Here is a reference:

http://msdn.microsoft.com/en-us/library/ms182776(v=sql.90).aspx

Here is a little RowVersion (synonym for timestamp) example:

CREATE TABLE [dbo].[Names]
(
    [Name] [nvarchar](64) NOT NULL,
    RowVers rowversion ,
    [CreateTS] [datetime] NOT NULL CONSTRAINT CreateTS_DF DEFAULT CURRENT_TIMESTAMP,
    [UpdateTS] [datetime] NOT NULL

)


INSERT INTO dbo.Names (Name,UpdateTS)
select 'John' , CURRENT_TIMESTAMP
UNION ALL select 'Mary' , CURRENT_TIMESTAMP
UNION ALL select 'Paul' , CURRENT_TIMESTAMP

select *  ,  ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]

Update dbo.Names Set Name = Name

select *  ,  ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]

Maybe a complete working example:

DROP TABLE [dbo].[Names]
GO


CREATE TABLE [dbo].[Names]
(
    [Name] [nvarchar](64) NOT NULL,
    RowVers rowversion ,
    [CreateTS] [datetime] NOT NULL CONSTRAINT CreateTS_DF DEFAULT CURRENT_TIMESTAMP,
    [UpdateTS] [datetime] NOT NULL

)

GO

CREATE TRIGGER dbo.trgKeepUpdateDateInSync_ByeByeBye ON dbo.Names
AFTER INSERT, UPDATE
AS

BEGIN

Update dbo.Names Set UpdateTS = CURRENT_TIMESTAMP from dbo.Names myAlias , inserted triggerInsertedTable where 
triggerInsertedTable.Name = myAlias.Name

END


GO






INSERT INTO dbo.Names (Name,UpdateTS)
select 'John' , CURRENT_TIMESTAMP
UNION ALL select 'Mary' , CURRENT_TIMESTAMP
UNION ALL select 'Paul' , CURRENT_TIMESTAMP

select *  ,  ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]

Update dbo.Names Set Name = Name , UpdateTS = '03/03/2003' /* notice that even though I set it to 2003, the trigger takes over */

select *  ,  ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]

Matching on the "Name" value is probably not wise.

Try this more mainstream example with a SurrogateKey

DROP TABLE [dbo].[Names]
GO


CREATE TABLE [dbo].[Names]
(
    SurrogateKey int not null Primary Key Identity (1001,1),
    [Name] [nvarchar](64) NOT NULL,
    RowVers rowversion ,
    [CreateTS] [datetime] NOT NULL CONSTRAINT CreateTS_DF DEFAULT CURRENT_TIMESTAMP,
    [UpdateTS] [datetime] NOT NULL

)

GO

CREATE TRIGGER dbo.trgKeepUpdateDateInSync_ByeByeBye ON dbo.Names
AFTER UPDATE
AS

BEGIN

   UPDATE dbo.Names
    SET UpdateTS = CURRENT_TIMESTAMP
    From  dbo.Names myAlias
    WHERE exists ( select null from inserted triggerInsertedTable where myAlias.SurrogateKey = triggerInsertedTable.SurrogateKey)

END


GO






INSERT INTO dbo.Names (Name,UpdateTS)
select 'John' , CURRENT_TIMESTAMP
UNION ALL select 'Mary' , CURRENT_TIMESTAMP
UNION ALL select 'Paul' , CURRENT_TIMESTAMP

select *  ,  ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]

Update dbo.Names Set Name = Name , UpdateTS = '03/03/2003' /* notice that even though I set it to 2003, the trigger takes over */

select *  ,  ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]

You can discover those things easily by yourself:

def hello(*args, **kwargs):
    print kwargs
    print type(kwargs)
    print dir(kwargs)

hello(what="world")

A Simple solution :

Create a drawable file as edittext_stroke.xml in drawable folder. Add the below code:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="line"
   >
    <stroke
        android:width="1dp"
        android:color="@android:color/white" >
    </stroke>
</shape>

In layout file , add the drawable to edittext as

android:drawableBottom="@drawable/edittext_stroke"

<EditText
      android:textColor="@android:color/white"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:drawableBottom="@drawable/edittext_stroke"
      />

In your Project open Global.asax.cs then right click on Method RouteConfig.RegisterRoutes(RouteTable.Routes); then click Go To Definition then at defaults: new { controller = "Home", action = "Index", id =UrlParameter.Optional} then change then Names of "Home" to your own controller Name and Index to your own View Name if you have changed the Names other then "HomeController" and "Index" Hope your Problem will be Solved.

you need to use ++$counter, not $++counter, hence the reason it isn't working..

I had the problem due to an extra space in the name of the linked server. "SERVER1, 1234" instead of "SERVER1,1234"

Here's a portable Unix (using grep and sed) one-liner that returns the version string of a globally-installed npm package (remove the g from -pg to query local packages instead):

$ npm ll -pg --depth=0 grunt | grep -o "@.*:" | sed 's/.$//; s/^.//'
0.4.5

• the npm ll outputs a parseable string formatted like: /usr/lib/node_modules/npm:[email protected]:;
• the grep command extracts the value between @ and :, inclusive;
• the sed command removes the surrounding characters.

Following on from jpw it might be good to encapsulate his solution in a small subroutine to save on having lots of lines of code:

Private Sub CommandButton1_Click()
Dim i As Integer
Dim a As Integer
a = 15
For i = 11 To 32
  If Worksheets(1).Cells(i, 3) <> "" Then
    call copValuesAndFormat(i,3,a,15)        
    call copValuesAndFormat(i,5,a,17) 
    call copValuesAndFormat(i,6,a,18) 
    call copValuesAndFormat(i,7,a,19) 
    call copValuesAndFormat(i,8,a,20) 
    call copValuesAndFormat(i,9,a,21) 
    a = a + 1
  End If
Next i
end sub

sub copValuesAndFormat(x1 as integer, y1 as integer, x2 as integer, y2 as integer)
  Worksheets(1).Cells(x1, y1).Copy
  Worksheets(2).Cells(x2, y2).PasteSpecial Paste:=xlPasteFormats
  Worksheets(2).Cells(x2, y2).PasteSpecial Paste:=xlPasteValues
end sub

(I do not have Excel in current location so please excuse bugs as not tested)

Assuming you have a button/link inside of a data cell in your table, something like this would do the trick...

$(".delete").live('click', function(event) {
    $(this).parent().parent().remove();
});

This will remove the parent of the parent of the button/link that is clicked. You need to use parent() because it is a jQuery object, not a normal DOM object, and you need to use parent() twice, because the button lives inside a data cell, which lives inside a row....which is what you want to remove. $(this) is the button clicked, so simply having something like this will remove only the button:

$(this).remove();

While this will remove the data cell:

    $(this).parent().remove();

If you want to simply click anywhere on the row to remove it something like this would work. You could easily modify this to prompt the user or work only on a double-click:

$(".delete").live('click', function(event) {
    $(this).parent().remove();
});

Hope that helps...I struggled on this a bit myself.

But this is obviously performing a 'string' comparison

No. The string will be automatically cast into a DATETIME value.

See 11.2. Type Conversion in Expression Evaluation.

When an operator is used with operands of different types, type conversion occurs to make the operands compatible. Some conversions occur implicitly. For example, MySQL automatically converts numbers to strings as necessary, and vice versa.

I know this seems to be already answered, but I ran into a specific case, and I feel most answers miss the point.

The overflow:hidden answers cover 90% of the cases. That's more or less the "sticky nav" scenario.

But the sticky behavior is best used within the height of a container. Think of a newsletter form in the right column of your website that scrolls down with the page. If your sticky element is the only child of the container, the container is the exact same size, and there's no room to scroll.

Your container needs to be the height you expect your element to scroll within. Which in my "right column" scenario is the height of the left column. The best way to achieve this is to use display:table-cell on the columns. If you can't, and are stuck with float:right and such like I was, you'll have to either guess the left column height of compute it with Javascript.

How about:

preg_replace('/\\?.*/', '', $str)

CSS

li {
   display: inline-block;
}

Works for me also.

You need to use the as.Date formats correctly.

Eg.

x = '2012/07/25'
xd = as.Date(x,'%Y/%m/%d')
xd    # Prints "2012-07-25"

R date formats are similary to *nix ones.

Doing a typeof(xd) shows it as a double ie. days since 1970.

Unless you want the canvas to upscale your image data automatically (that's what James Black's answer talks about, but it won't look pretty), you have to resize it yourself and redraw the image. Centering a canvas

You only need this link jspdf.min.js

It has everything in it.

<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.3.2/jspdf.min.js"></script>

I ended up using a definition list with an unordered list inside it. It solves the issue of the unwanted space above the list without needing to change every paragraph tag.

<dl><dt>Text</dt>
<dd><ul><li>First item</li>
<li>Second item</li></ul></dd></dl>

This is a simple word counter using regex. The script includes a loop which you can terminate it when you're done.

#word counter using regex
import re
while True:
    string =raw_input("Enter the string: ")
    count = len(re.findall("[a-zA-Z_]+", string))
    if line == "Done": #command to terminate the loop
        break
    print (count)
print ("Terminated")

Quick and dirty:

LP == Long Pointer. Just think pointer or char*

C = Const, in this case, I think they mean the character string is a const, not the pointer being const.

STR is string

the T is for a wide character or char (TCHAR) depending on compile options.

If your not overly worried about the size of the file then it may be easier for you to store the data as a JS object in another file and import it in your . Either synchronously or asynchronously using the syntax <script src="countries.js" async></script>. Saves on you needing to import the file and parse it.

However, i can see why you wouldnt want to rewrite 10000 entries so here's a basic object orientated csv parser i wrote.

function requestCSV(f,c){return new CSVAJAX(f,c);};
function CSVAJAX(filepath,callback)
{
    this.request = new XMLHttpRequest();
    this.request.timeout = 10000;
    this.request.open("GET", filepath, true);
    this.request.parent = this;
    this.callback = callback;
    this.request.onload = function() 
    {
        var d = this.response.split('\n'); /*1st separator*/
        var i = d.length;
        while(i--)
        {
            if(d[i] !== "")
                d[i] = d[i].split(','); /*2nd separator*/
            else
                d.splice(i,1);
        }
        this.parent.response = d;
        if(typeof this.parent.callback !== "undefined")
            this.parent.callback(d);
    };
    this.request.send();
};

Which can be used like this;

var foo = requestCSV("csvfile.csv",drawlines(lines)); 

The first parameter is the file, relative to the position of your html file in this case. The second parameter is an optional callback function the runs when the file has been completely loaded.

If your file has non-separating commmas then it wont get on with this, as it just creates 2d arrays by chopping at returns and commas. You might want to look into regexp if you need that functionality.

//THIS works 

"1234","ABCD" \n
"!@£$" \n

//Gives you 
[
 [
  1234,
  'ABCD'
 ],
 [
  '!@£$'
 ]
]

//This DOESN'T!

"12,34","AB,CD" \n
"!@,£$" \n

//Gives you

[
 [
  '"12',
  '34"',
  '"AB',
  'CD'
 ]
 [
  '"!@',
  '£$'
 ]
]

If your not used to the OO methods; they create a new object (like a number, string, array) with their own local functions and variables via a 'constructor' function. Very handy in certain situations. This function could be used to load 10 different files with different callbacks all at the same time(depending on your level of csv love! )

n_values = data.income.value_counts()

First unique value count

n_at_most_50k = n_values[0]

Second unique value count

n_greater_50k = n_values[1]

n_values

Output:

<=50K    34014
>50K     11208

Name: income, dtype: int64

Output:

n_greater_50k,n_at_most_50k:-
(11208, 34014)

Another interesting solution might be to do this:

<a href="#" itemid="<%itemid%>" itemname="<%itemname%>" onclick="SelectSurveyItem(this.itemid, this.itemname); return false;">Select</a>

Then you can use a standard HTML-encoding on both the variables, without having to worry about the extra complication of the javascript quoting.

Yes, this does create HTML that is strictly invalid. However, it is a valid technique, and all modern browsers support it.

If it was my, I'd probably go with my first suggestion, and ensure the values are HTML-encoded and have single-quotes escaped.

There's been a fair amount of recent research in considering how REST HTTP calls could replace the message queue concept.

If you introduce the concept of a process and a task as a resource, the need for middle messaging layer starts to evaporate.

Ex:

POST /task/name
    - Returns a 202 accepted status immediately
    - Returns a resource url for the created task: /task/name/X
    - Returns a resource url for the started process: /process/Y

GET /process/Y
    - Returns status of ongoing process

A task can have multiple steps for initialization, and a process can return status when polled or POST to a callback URL when complete.

This is dead simple, and becomes quite powerful when you realize that you can now subscribe to an rss/atom feed of all running processes and tasks without any middle layer. Any queuing system is going to require some sort of web front end anyway, and this concept has it built in without another layer of custom code.

Your resources exist until you delete them, which means you can view historical information long after the process and task complete.

You have built in service discovery, even for a task that has multiple steps, without any extra complicated protocols.

GET /task/name
    - returns form with required fields

POST (URL provided form's "action" attribute)

Your service discovery is an HTML form - a universal and human readable format.

The entire flow can be used programmatically or by a human, using universally accepted tools. It's a client driven, and therefore RESTful. Every tool created for the web can drive your business processes. You still have alternate message channels by POSTing asynchronously to a separate array of log servers.

After you consider it for a while, you sit back and start to realize that REST may just eliminate the need for a messaging queue and an ESB altogether.

In theory SMTP can be handled by either TCP, UDP, or some 3rd party protocol.

As defined in RFC 821, RFC 2821, and RFC 5321:

SMTP is independent of the particular transmission subsystem and requires only a reliable ordered data stream channel.

In addition, the Internet Assigned Numbers Authority has allocated port 25 for both TCP and UDP for use by SMTP.

In practice however, most if not all organizations and applications only choose to implement the TCP protocol. For example, in Microsoft's port listing port 25 is only listed for TCP and not UDP.

The big difference between TCP and UDP that makes TCP ideal here is that TCP checks to make sure that every packet is received and re-sends them if they are not whereas UDP will simply send packets and not check for receipt. This makes UDP ideal for things like streaming video where every single packet isn't as important as keeping a continuous flow of packets from the server to the client.

Considering SMTP, it makes more sense to use TCP over UDP. SMTP is a mail transport protocol, and in mail every single packet is important. If you lose several packets in the middle of the message the recipient might not even receive the message and if they do they might be missing key information. This makes TCP more appropriate because it ensures that every packet is delivered.

in my case, I forget to add (or deleted accidentally) firebase core in build gradle

implementation 'com.google.firebase:firebase-core:xx.x.x'

To remove one or more columns by name, when the column names are known (as opposed to being determined at run-time), I like the subset() syntax. E.g. for the data-frame

df <- data.frame(a=1:3, d=2:4, c=3:5, b=4:6)

to remove just the a column you could do

Data <- subset( Data, select = -a )

and to remove the b and d columns you could do

Data <- subset( Data, select = -c(d, b ) )

You can remove all columns between d and b with:

Data <- subset( Data, select = -c( d : b )

As I said above, this syntax works only when the column names are known. It won't work when say the column names are determined programmatically (i.e. assigned to a variable). I'll reproduce this Warning from the ?subset documentation:

Warning:

This is a convenience function intended for use interactively. For programming it is better to use the standard subsetting functions like '[', and in particular the non-standard evaluation of argument 'subset' can have unanticipated consequences.

If you only need to show time value in a datagrid or label similar, best way is convert directly time in datetime datatype.

SELECT CONVERT(datetime,myTimeField) as myTimeField FROM Table1

Web containers are responsible to provide the run time environment to web applications. It contains components that provide naming context and manages the life cycle of a web application. Web containers are a part of a web server and they generally processes the user request and send a static response.

Servlet containers are the one where JSP created components reside. They are basically responsible to provide dynamic content as per the user request. Basically, Web containers reply with a static content as per the user request, but Servlets can create the dynamic pages.

i solved this issue

go to cmd and execute aspnet_regiis -i

hope it helpful to someone.

Modern C, aka C99, has variable length arrays, VLA. Unfortunately, not all compilers support this but if yours does this would be an alternative.

Collation can be set at various levels:

1. Server
2. Database
3. Column

So you could have a Case Sensitive Column in a Case Insensitive database. I have not yet come across a situation where a business case could be made for case sensitivity of a single column of data, but I suppose there could be.

Check Server Collation

SELECT SERVERPROPERTY('COLLATION')

Check Database Collation

SELECT DATABASEPROPERTYEX('AdventureWorks', 'Collation') SQLCollation;

Check Column Collation

select table_name, column_name, collation_name
from INFORMATION_SCHEMA.COLUMNS
where table_name = @table_name

Or just call mysql command with --version option.

mysql --version

Run PHP file from command Promp.

Please set Environment Variable as per below mention steps.

1. Right Click on MY Computer Icon and Click on Properties or Go to "Control Panel\System and Security\System".
2. Select "Advanced System Settings" and select "Advance" Tab
3. Now Select "Environment Variable" option and select "Path" from "System Variables" and click on "Edit" button
4. Now set path where php.exe file is available - For example if XAMPP install in to C: drive then Path is "C:\xampp\php"
5. After set path Click Ok and Apply.

Now open Command prompt where your source file are available and run command "php test.php"

It manages them because int and long are sibling class definitions. They have appropriate methods for +, -, *, /, etc., that will produce results of the appropriate class.

For example

>>> a=1<<30
>>> type(a)
<type 'int'>
>>> b=a*2
>>> type(b)
<type 'long'>

In this case, the class int has a __mul__ method (the one that implements *) which creates a long result when required.

Here's a simple way to test it:

public class OperatorTest {     
    public static void main(String[] args) {
        boolean a = false;
        a &= b();
    }

    private static boolean b() {
        System.out.println("b() was called");
        return true;
    }
}

The output is b() was called, therefore the right-hand operand is evaluated.

So, as already mentioned by others, a &= b is the same as a = a & b.

I am having the same issue on IE9.

I will just use a RegExp to strip all the white spaces before writing the HTML to the page.

var Tables=$('##table_ID').html();
var expr = new RegExp('>[ \t\r\n\v\f]*<', 'g');
Tables= Tables.replace(expr, '><');
$('##table_ID').html(Tables);
oTable = $('##table_ID').dataTable( {
  "bPaginate": false,
  "bLengthChange": false,
  "bFilter": false,
  "bSort": true,
  "bInfo": true,
  "bAutoWidth": false,
  "sScrollY": ($(window).height() - 320),
  "sScrollX": "100%",
  "iDisplayLength":-1,
  "sDom": 'rt<"bottom"i flp>'
} );

The server's address is stored in config.php

Disablend ScrollView

ScrollView sw = (ScrollView) findViewById(R.id.scrollView1);
sw.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        return true;
    }
});

A control or window object in Windows Forms is just a wrapper around a Win32 window identified by a handle (sometimes called HWND). Most things you do with the control will eventually result in a Win32 API call that uses this handle. The handle is owned by the thread that created it (typically the main thread), and shouldn't be manipulated by another thread. If for some reason you need to do something with the control from another thread, you can use Invoke to ask the main thread to do it on your behalf.

For instance, if you want to change the text of a label from a worker thread, you can do something like this:

theLabel.Invoke(new Action(() => theLabel.Text = "hello world from worker thread!"));

You can add multiple base packages (see axtavt's answer), but you can also filter what's scanned inside the base package:

<context:component-scan base-package="x.y.z">
   <context:include-filter type="regex" expression="(service|controller)\..*"/>
</context:component-scan>

var timeArr = moment().format('x');

returns the Unix Millisecond Timestamp as per the format() documentation.

I was looking for a way to debug code in a WordPress plugin that I was developing and came across this post.

I took the bits of code that are most applicable to me from other responses and combined these into a function that I can use for debugging WordPress. The function is:

function debug_log($object=null, $label=null, $priority=1) {
    $priority = $priority<1? 1: $priority;
    $message = json_encode($object, JSON_PRETTY_PRINT);
    $label = "Debug" . ($label ? " ($label): " : ': ');
    echo "<script>console.log('" . str_repeat("-", $priority-1) . $label . "', " . $message . ");</script>";
}

Usage is as follows:

$txt = 'This is a test string';
$sample_array = array('cat', 'dog', 'pig', 'ant', 'fly');
debug_log($txt, '', 7);
debug_log($sample_array);

If this function is used with WordPress development, the function should be placed in the functions.php file of the child theme and can then be called anywhere in the code.

Even after toggling it did not work. I closed and restarted the browser after adding the postman plugin, logged into the site to generate cookies afresh and then it worked for me.

Solution that worked for me:

• Delete node_modules and dist folder
• (in cmd)>> ng update --all --force
• (in cmd)>> npm install typescript@">=3.4.0 and <3.5.0" --save-dev --save-exact
• (in cmd)>> npm install --save core-js
• Commenting import 'core-js/es7/reflect'; in polyfill.ts
• (in cmd)>> ng serve

There are two ways to go about doing this.

1. Create a state in the constructor that contains the text input. Attach an onChange event to the input box that updates state each time. Then onClick you could just alert the state object.

2. handleClick: function() { alert(this.refs.myInput.value); },

In simple words, wait is wait Until some other thread invokes you whereas sleep is "dont execute next statement" for some specified period of time.

Moreover sleep is static method in Thread class and it operates on thread, whereas wait() is in Object class and called on an object.

Another point, when you call wait on some object, the thread involved synchronize the object and then waits. :)

Another approach

Say you create a class clsBitcoinPublicKey

In the class module create an ADDITIONAL subroutine, that acts as you would want the real constructor to behave. Below I have named it ConstructorAdjunct.

Public Sub ConstructorAdjunct(ByVal ...)

 ...

End Sub

From the calling module, you use an additional statement

Dim loPublicKey AS clsBitcoinPublicKey

Set loPublicKey = New clsBitcoinPublicKey

Call loPublicKey.ConstructorAdjunct(...)

The only penalty is the extra call, but the advantage is that you can keep everything in the class module, and debugging becomes easier.

I struggled with issue for 5 days and could get the source of the problem through Event Viewer Logs; Port 443, my application trying to access was in use, so I had to change the registry settings ; Basically you will b able to reach to source of issue thru error logs in event viewer.

I did this to be able to update the value of ngModel from the outside with Vanilla/jQuery:

function getScope(fieldElement) {
    var $scope = angular.element(fieldElement).scope();
    var nameScope;
    var name = fieldElement.getAttribute('name');
    if($scope) {
        if($scope.form) {
            nameScope = $scope.form[name];
        } else if($scope[name]) {
            nameScope = $scope[name];
        }
    }
    return nameScope;
}

function setScopeValue(fieldElement, newValue) {
    var $scope = getScope(fieldElement);
    if($scope) {
        $scope.$setViewValue(newValue);
        $scope.$validate();
        $scope.$render();
    }
}

setScopeValue(document.getElementById("fieldId"), "new value");

in "stdapi.h"

StrToInt

This function tells you the result, and how many characters participated in the conversion.

To find a particular Element is present or not, we have to use findElements() method instead of findElement()..

int i=driver.findElements(By.xpath(".......")).size();
if(i=0)
System.out.println("Element is not present");
else
System.out.println("Element is present");

this is worked for me.. suggest me if i am wrong..

My favorite example is "int Num = 5" here your variable is 1. defined as int 2. declared as Num and 3. instantiated with a value of five. We

• Define the type of an object, which may be built-in or a class or struct.
• Declare the name of an object, so anything with a name has been declared which includes Variables, Funtions, etc.

A class or struct allows you to change how objects will be defined when it is later used. For example

• One may declare a heterogeneous variable or array which are not specifically defined.
• Using an offset in C++ you may define an object which does not have a declared name.

When we learn programming these two terms are often confused because we often do both at the same time.

The best option now is to install the Microsoft Visual Studio add on called Productivity Power Tools.

With this comes "Solution Navigator" (alternative to Solution Explorer, with a lot of benefits) - which then you can use to filter the files to only show "Open". You can even filter files to show "Edited" and "Unsaved".

#import "SCLAlertView-Swift.h"

you can use this simple command instead of using a for loop,

I ran into a field where .clear() did not work. Using a combination of the first two answers worked for this field.

from selenium.webdriver.common.keys import Keys

#...your code (I was using python 3)

driver.find_element_by_id('foo').send_keys(Keys.CONTROL + "a");
driver.find_element_by_id('foo').send_keys(Keys.DELETE);

If you want to use @OverZealous' answer (https://stackoverflow.com/a/21806974/1019307) in Typescript, you need to import instead of require:

import * as debug from 'gulp-debug';

...

    return gulp.src('./examples/*.html')
        .pipe(debug({title: 'example src:'}))
        .pipe(gulp.dest('./build'));

(I also added a title).

In my case the database was running on non standard port. Check that the port you are connecting is the same as the port the database is running on. If there are more instances of SQL server, check the correct one.

+------+----------------------+
| type |        names         |
+------+----------------------+
| cat  | Felon                |
| cat  | Purz                 |
| dog  | Fido                 |
| dog  | Beethoven            |
| dog  | Buddy                |
| bird | Tweety               |
+------+----------------------+

select group_concat(name) from Pets
group by type

Here you can easily get the answer in single SQL and by using group by in your SQL you can separate the result based on that column value. Also you can use your own custom separator for splitting values

Result:

+------+----------------------+
| type |        names         |
+------+----------------------+
| cat  | Felon,Purz           |
| dog  | Fido,Beethoven,Buddy |
| bird | Tweety               |
+------+----------------------+

Short answer: You should to use "weak references" between collections, using ObjectId properties:

References store the relationships between data by including links or references from one document to another. Applications can resolve these references to access the related data. Broadly, these are normalized data models.

https://docs.mongodb.com/manual/core/data-modeling-introduction/#references

This will of course not check any referential integrity. You need to handle "dead links" on your side (application level).

Here's a data.table solution that will list the duplicates along with the number of duplications (will be 1 if there are 2 copies, and so on - you can adjust that to suit your needs):

library(data.table)
dt = data.table(vocabulary)

dt[duplicated(id), cbind(.SD[1], number = .N), by = id]

If you're using c# you can use this code:

using System.Runtime.InteropServices;

    [DllImport("kernel32.dll", SetLastError = true)]
    static extern IntPtr LocalFree(IntPtr hMem);

    [DllImport("kernel32.dll", SetLastError = true)]
    static extern int FormatMessage(FormatMessageFlags dwFlags, IntPtr lpSource, uint dwMessageId, uint dwLanguageId, ref IntPtr lpBuffer, uint nSize, IntPtr Arguments);

    [Flags]

        FORMAT_MESSAGE_FROM_SYSTEM = 0x00001000,
        FORMAT_MESSAGE_ARGUMENT_ARRAY = 0x00002000,
        FORMAT_MESSAGE_FROM_HMODULE = 0x00000800,
        FORMAT_MESSAGE_FROM_STRING = 0x00000400,
    }
    #endregion

    public static string GetSystemMessage(int errorCode)
    {
        try
        {
            IntPtr lpMsgBuf = IntPtr.Zero;

            int dwChars = FormatMessage(
                FormatMessageFlags.FORMAT_MESSAGE_ALLOCATE_BUFFER | FormatMessageFlags.FORMAT_MESSAGE_FROM_SYSTEM | FormatMessageFlags.FORMAT_MESSAGE_IGNORE_INSERTS,
                IntPtr.Zero,
                (uint) errorCode,
                0, // Default language
                ref lpMsgBuf,
                0,
                IntPtr.Zero);
            if (dwChars == 0)
            {
                // Handle the error.
                int le = Marshal.GetLastWin32Error();
                return "Unable to get error code string from System - Error " + le.ToString();
            }

            string sRet = Marshal.PtrToStringAnsi(lpMsgBuf);

            // Free the buffer.
            lpMsgBuf = LocalFree(lpMsgBuf);
            return sRet;
        }
        catch (Exception e)
        {
            return "Unable to get error code string from System -> " + e.ToString();
        }
    }
}

OFFSET     10 ROWS       -- skip 10 rows

use this in the end of your select syntax. =)

HTTP is an application protocol. REST is a set of rules, that when followed, enable you to build a distributed application that has a specific set of desirable constraints.

If you are looking for the most significant constraints of REST that distinguish a RESTful application from just any HTTP application, I would say the "self-description" constraint and the hypermedia constraint (aka Hypermedia as the Engine of Application State (HATEOAS)) are the most important.

The self-description constraint requires a RESTful request to be completely self descriptive in the users intent. This allows intermediaries (proxies and caches) to act on the message safely.

The HATEOAS constraint is about turning your application into a web of links where the client's current state is based on its place in that web. It is a tricky concept and requires more time to explain than I have right now.

You can use Data::Dump:

use Data::Dump qw(dump);
my @a = (1, [2, 3], {4 => 5});
dump(@a);

Produces:

"(1, [2, 3], { 4 => 5 })"

Visual Studio 2017

1. Open Visual Studio
2. In Tools -> Extensions and Updates -> Online
3. Search for 'rdlc'
4. Install Microsoft Rdlc Report Designer (23.3 MB)
5. Close Visual Studio, let the installer run and open Visual Studio to see the rdlc in the designer.

The answer is yes, double printing is broken in .NET, they are printing trailing garbage digits.

You can read how to implement it correctly here.

I have had to do the same for IronScheme.

6.8999999999999995

Note: Both C and C# has correct value, just broken printing.

Update: I am still looking for the mailing list conversation I had that lead up to this discovery.

You should probably clarify which logger are you using.

org.apache.commons.logging.Log interface has method void error(Object message, Throwable t) (and method void info(Object message, Throwable t)), which logs the stack trace together with your custom message. Log4J implementation has this method too.

So, probably you need to write:

logger.error("BOOM!", e);

If you need to log it with INFO level (though, it might be a strange use case), then:

logger.info("Just a stack trace, nothing to worry about", e);

Hope it helps.

As of jquery ui version 1.8.16 below is how I got it working.

$('#element').dialog({
  buttons: { 
      "Save": {  
          text: 'Save', 
          class: 'btn primary', 
          click: function () {
              // do stuff
          }
      }
});

After searching around a bit, the best solution in my opinion makes use of hudson.model.EnvironmentContributingAction.

import hudson.model.EnvironmentContributingAction
import hudson.model.AbstractBuild 
import hudson.EnvVars

class BuildVariableInjector {

    def build
    def out

    def BuildVariableInjector(build, out) {
        this.build = build
        this.out = out
    }

    def addBuildEnvironmentVariable(key, value) {
        def action = new VariableInjectionAction(key, value)
        build.addAction(action)
        //Must call this for action to be added
        build.getEnvironment()
    }

    class VariableInjectionAction implements EnvironmentContributingAction {

        private String key
        private String value

        public VariableInjectionAction(String key, String value) {
            this.key = key
            this.value = value
        }

        public void buildEnvVars(AbstractBuild build, EnvVars envVars) {

            if (envVars != null && key != null && value != null) {
                envVars.put(key, value);
            }
        }

        public String getDisplayName() {
            return "VariableInjectionAction";
        }

        public String getIconFileName() {
            return null;
        }

        public String getUrlName() {
            return null;
        }
    }    
}

I use this class in a system groovy script (using the groovy plugin) within a job.

import hudson.model.*
import java.io.File;
import jenkins.model.Jenkins;    

def jenkinsRootDir = build.getEnvVars()["JENKINS_HOME"];
def parent = getClass().getClassLoader()
def loader = new GroovyClassLoader(parent)

def buildVariableInjector = loader.parseClass(new File(jenkinsRootDir + "/userContent/GroovyScripts/BuildVariableInjector.groovy")).newInstance(build, getBinding().out)

def projectBranchDependencies = [] 
//Some logic to set projectBranchDependencies variable

buildVariableInjector.addBuildEnvironmentVariable("projectBranchDependencies", projectBranchDependencies.join(","));

You can then access the projectBranchDependencies variable at any other point in your build, in my case, from an ANT script.

Note: I borrowed / modified the ideas for parts of this implementation from a blog post, but at the time of this posting I was unable to locate the original source in order to give due credit.

@miyuru. As suggested by him run all the steps.

Ubuntu version 16.04

Still when I ran docker --version it was returning a version. So to uninstall it completely

Again run the dpkg -l | grep -i docker which will list package still there in system.

For example:

ii  docker-ce-cli      5:19.03.6~3-0~ubuntu-xenial               
amd64        Docker CLI: the open-source application container engine

Now remove them as show below :

sudo apt-get purge -y docker-ce-cli

sudo apt-get autoremove -y --purge docker-ce-cli

sudo apt-get autoclean

Hope this will resolve it, as it did in my case.
