Yes, it is because you are using auto layout. Setting the view frame and resizing mask will not work.

You should read Working with Auto Layout Programmatically and Visual Format Language.

You will need to get the current constraints, add the text field, adjust the contraints for the text field, then add the correct constraints on the text field.

  let button: UIButton = UIButton()
    button.setImage(UIImage(named:"imagename"), for: .normal)
    button.addTarget(self, action:#selector(YourClassName.backAction(_sender:)), for: .touchUpInside)

    button.frame = CGRect.init(x: 5, y: 100, width: 45, height: 45)
    view.addSubview(button)

    @objc public func backAction(_sender: UIButton) {

    }

Constraints for multiple views in playground.

swift 3+

  var yellowView: UIView!
    var redView: UIView!

    override func loadView() {

        // UI

        let view = UIView()
        view.backgroundColor = .white

        yellowView = UIView()
        yellowView.backgroundColor = .yellow
        view.addSubview(yellowView)

        redView = UIView()
        redView.backgroundColor = .red
        view.addSubview(redView)

        // Layout
        redView.translatesAutoresizingMaskIntoConstraints = false
        yellowView.translatesAutoresizingMaskIntoConstraints = false
        NSLayoutConstraint.activate([
            yellowView.topAnchor.constraint(equalTo: view.topAnchor, constant: 20),
            yellowView.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: 20),
            yellowView.widthAnchor.constraint(equalToConstant: 80),
            yellowView.heightAnchor.constraint(equalToConstant: 80),

            redView.bottomAnchor.constraint(equalTo: view.bottomAnchor, constant: -20),
            redView.trailingAnchor.constraint(equalTo: view.trailingAnchor,constant: -20),
            redView.widthAnchor.constraint(equalToConstant: 80),
            redView.heightAnchor.constraint(equalToConstant: 80)
            ])

        self.view = view
    }

In my opinion xcode playground is the best place for learning adding constraints programmatically.

The headers only remain fixed when the UITableViewStyle property of the table is set to UITableViewStylePlain. If you have it set to UITableViewStyleGrouped, the headers will scroll up with the cells.

Thanks guys. I solved this problem through your help. So, I hope this screenshot helpful to person who have same problem.

I was also getting the same issue of breaking constraints in the log, for a viewCircle in the xib. I almost tried everything listed above and nothing was working for me. Then I tried to change the priority of the Height constraint which was breaking in the log(confirmed by adding an identifiers for the constraints on the xib)enter image description here

UIImage*image = [UIImage imageNamed:@"logo"];

float targetHeight = self.navigationController.navigationBar.frame.size.height;
float logoRatio = image.size.width / image.size.height;
float targetWidth = targetHeight * logoRatio;

UIImageView*logoView = [[UIImageView alloc] initWithImage:image];
// X or Y position can not be manipulated because autolayout handles positions.
//[logoView setFrame:CGRectMake((self.navigationController.navigationBar.frame.size.width - targetWidth) / 2 , (self.navigationController.navigationBar.frame.size.height - targetHeight) / 2 , targetWidth, targetHeight)];
[logoView setFrame:CGRectMake(0, 0, targetWidth, targetHeight)];
self.navigationItem.titleView = logoView;

// How much you pull out the strings and struts, with autolayout, your image will fill the width on navigation bar. So setting only height and content mode is enough/
[logoView setContentMode:UIViewContentModeScaleAspectFit];

/* Autolayout constraints also can not be manipulated since navigation bar has  immutable constraints
self.navigationItem.titleView.translatesAutoresizingMaskIntoConstraints = false;

NSDictionary*metricsArray = @{@"width":[NSNumber numberWithFloat:targetWidth],@"height":[NSNumber numberWithFloat:targetHeight],@"margin":[NSNumber numberWithFloat:20]};
NSDictionary*viewsArray = @{@"titleView":self.navigationItem.titleView};

[self.navigationItem.titleView addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"|-(>margin=)-H:[titleView(width)]-(>margin=)-|" options:NSLayoutFormatAlignAllCenterX metrics:metricsArray views:viewsArray]];
[self.navigationItem.titleView addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:[titleView(height)]" options:0 metrics:metricsArray views:viewsArray]];

NSLog(@"%f", self.navigationItem.titleView.width );
*/

So all we actually need is

UIImage*image = [UIImage imageNamed:@"logo"];
UIImageView*logoView = [[UIImageView alloc] initWithImage:image];
float targetHeight = self.navigationController.navigationBar.frame.size.height;
[logoView setFrame:CGRectMake(0, 0, 0, targetHeight)];
[logoView setContentMode:UIViewContentModeScaleAspectFit];

self.navigationItem.titleView = logoView;

image view add as a sub view to the tableview cell

UIImageView *imgView=[[UIImageView alloc] initWithFrame:CGRectMake(20, 5, 90, 70)];
imgView.backgroundColor=[UIColor clearColor];
[imgView.layer setCornerRadius:8.0f];
[imgView.layer setMasksToBounds:YES];
[imgView setImage:[UIImage imageWithData: imageData]];
[cell.contentView addSubview:imgView];

Based on this answer, I did this in my React component:

export default React.memo(() => {
    const containerRef = React.useRef(null);

    React.useEffect(() => {
        document.addEventListener('mousedown', handleMouseMove);

        return () => document.removeEventListener('mousedown', handleMouseMove);
    }, []);

    const handleMouseMove = React.useCallback(() => {
        const drag = (e) => {
            console.log('mouse is moving');
        };

        const lift = (e) => {
            console.log('mouse move ended');
            window.removeEventListener('mousemove', drag);
            window.removeEventListener('mouseup', this);
        };

        window.addEventListener('mousemove', drag);
        window.addEventListener('mouseup', lift);
    }, []);

    return (
        <div style={{ width: '100vw', height: '100vh' }} ref={containerRef} />
    );
})

Here is an example that works on Chrome 5.0.375.125.

The page B (iframe content):

<html>
    <head></head>
    <body>
        <script>
            top.postMessage('hello', 'A');
        </script>
    </body>
</html>

Note the use of top.postMessage or parent.postMessage not window.postMessage here

The page A:

<html>
<head></head>
<body>
    <iframe src="B"></iframe>
    <script>
        window.addEventListener( "message",
          function (e) {
                if(e.origin !== 'B'){ return; } 
                alert(e.data);
          },
          false);
    </script>
</body>
</html>

A and B must be something like http://domain.com

EDIT:

From another question, it looks the domains(A and B here) must have a / for the postMessage to work properly.

I have found this better way , no need to remove data , just call the source of the remote content each time

$(document).ready(function() {
    $('.class').click(function() {
        var id = this.id;
        //alert(id);checking that have correct id
        $("#iframe").attr("src","url?id=" + id);
        $('#Modal').modal({ 
            show: true 
        });
    });
});

If you want to pause then use java.util.concurrent.TimeUnit:

TimeUnit.SECONDS.sleep(1);

To sleep for one second or

TimeUnit.MINUTES.sleep(1);

To sleep for a minute.

As this is a loop, this presents an inherent problem - drift. Every time you run code and then sleep you will be drifting a little bit from running, say, every second. If this is an issue then don't use sleep.

Further, sleep isn't very flexible when it comes to control.

For running a task every second or at a one second delay I would strongly recommend a ScheduledExecutorService and either scheduleAtFixedRate or scheduleWithFixedDelay.

For example, to run the method myTask every second (Java 8):

public static void main(String[] args) {
    final ScheduledExecutorService executorService = Executors.newSingleThreadScheduledExecutor();
    executorService.scheduleAtFixedRate(App::myTask, 0, 1, TimeUnit.SECONDS);
}

private static void myTask() {
    System.out.println("Running");
}

And in Java 7:

public static void main(String[] args) {
    final ScheduledExecutorService executorService = Executors.newSingleThreadScheduledExecutor();
    executorService.scheduleAtFixedRate(new Runnable() {
        @Override
        public void run() {
            myTask();
        }
    }, 0, 1, TimeUnit.SECONDS);
}

private static void myTask() {
    System.out.println("Running");
}

I have come to opinion that the question is the best answer :)

import json
from urllib.request import urlopen

response = urlopen("site.com/api/foo/bar").read().decode('utf8')
obj = json.loads(response)

You're close. A really simple solution is just to get the length from the 'run' objects returned. No need to bother with 'load' or 'loads':

len(data['result'][0]['run'])

I suggest you take a look at the code on kevinsawicki/http-request, its basically a wrapper on top of HttpUrlConnection it provides a much simpler API in case you just want to make the requests right now or you can take a look at the sources (it's not too big) to take a look at how connections are handled.

Example: Make a GET request with content type application/json and some query parameters:

// GET http://google.com?q=baseball%20gloves&size=100
String response = HttpRequest.get("http://google.com", true, "q", "baseball gloves", "size", 100)
        .accept("application/json")
        .body();
System.out.println("Response was: " + response);

If you know the position, why not just get the index from that?

Then use .loc:

df.loc[index, 'COL_NAME'] = x

I know this thread is old, but since a Google search brought me here, it will also do to other people who may find this useful.

Microsoft recenly launched Visual Studio Online, which is free for projects with up to 5 users:

http://www.visualstudio.com/en-us/products/visual-studio-online-overview-vs.aspx

I have been using it for a while, and it integrates completely with Visual Studio 2013. It claims integration with other IDEs too. Apart from TFS, Git can also be used with it.

I know this thread is old, but since a Google search brought me here

Well I'm not getting the "last value" in a table, I'm getting the Last value per financial instrument. It's not the same but I guess it is relevant for some that are looking to look up on "how it is done now". I also used RowNumber() and CTE's and before that to simply take 1 and order by [column] desc. however we nolonger need to...

I am using SQL server 2017, we are recording all ticks on all exchanges globally, we have ~12 billion ticks a day, we store each Bid, ask, and trade including the volumes and the attributes of a tick (bid, ask, trade) of any of the given exchanges.

We have 253 types of ticks data for any given contract (mostly statistics) in that table, the last traded price is tick type=4 so, when we need to get the "last" of Price we use :

select distinct T.contractId,
LAST_VALUE(t.Price)over(partition by t.ContractId order by created ROWS BETWEEN CURRENT ROW AND UNBOUNDED FOLLOWING)
from [dbo].[Tick] as T
where T.TickType=4

You can see the execution plan on my dev system it executes quite efficient, executes in 4 sec while the exchange import ETL is pumping data into the table, there will be some locking slowing me down... that's just how live systems work.

It can also be due to a duplicate entry in any of the tables that are used.

In Firefox, these function behave quite differently: log only prints out a toString representation, whereas dir prints out a navigable tree.

In Chrome, log already prints out a tree -- most of the time. However, Chrome's log still stringifies certain classes of objects, even if they have properties. Perhaps the clearest example of a difference is a regular expression:

> console.log(/foo/);
/foo/

> console.dir(/foo/);
* /foo/
    global: false
    ignoreCase: false
    lastIndex: 0
    ...

You can also see a clear difference with arrays (e.g., console.dir([1,2,3])) which are logged differently from normal objects:

> console.log([1,2,3])
[1, 2, 3]

> console.dir([1,2,3])
* Array[3]
    0: 1
    1: 2
    2: 3
    length: 3
    * __proto__: Array[0]
        concat: function concat() { [native code] }
        constructor: function Array() { [native code] }
        entries: function entries() { [native code] }
        ...

DOM objects also exhibit differing behavior, as noted on another answer.

You can specify a new column. You also need to compute the mean along the rows, so use axis=1.

df['mean'] = df.mean(axis=1)
>>> df
       Y1961      Y1962      Y1963      Y1964      Y1965 Region       mean

You shouldn't have to set height: 100% at any point if you want your container to fill the page. Chances are, your problem is rooted in the fact that you haven't cleared the floats in the container's children. There are quite a few ways to solve this problem, mainly adding overflow: hidden to the container.

#container { overflow: hidden; }

Should be enough to solve whatever height problem you're having.

Express.js created by TJ Holowaychuk and now managed by the community. It is one of the most popular frameworks in the node.js. Express can also be used to develop various products such as web applications or RESTful API.For more information please read on the expressjs.com official site.

If you are using material-ui, go to type definition of the component, which is being underlined by TypeScript. Most likely you will see something like this

export { default } from './ComponentName';

You have 2 options to resolve the error:

1.Add .default when using the component in JSX:

import ComponentName from './ComponentName'

const Component = () => <ComponentName.default />

2.Rename the component, which is being exported as "default", when importing:

import { default as ComponentName } from './ComponentName'

const Component = () => <ComponentName />

This way you don't need to specify .default every time you use the component.

The question is specific to SQL Server, but I would like to extend Martin Smith's answer.

SQL:2003 standard allows to define multiple values for simple case expression:

SELECT CASE c.Number
          WHEN '1121231','31242323' THEN 1
          WHEN '234523','2342423' THEN 2
       END AS Test
FROM tblClient c;

It is optional feature: Comma-separated predicates in simple CASE expression“ (F263).

Syntax:

CASE <common operand>
     WHEN <expression>[, <expression> ...] THEN <result>
    [WHEN <expression>[, <expression> ...] THEN <result>
     ...]
    [ELSE <result>]
END

As for know I am not aware of any RDBMS that actually supports that syntax.

You must setup postgresql-server-dev-X.Y, where X.Y. your's servers version, and it will install libpq-dev and other servers variables at modules for server side developing. In my case it was

apt-get install postgresql-server-dev-9.5

Reading package lists... Done Building dependency tree Reading state information... Done The following packages were automatically installed and are no longer required: libmysqlclient18 mysql-common Use 'apt-get autoremove' to remove them. The following extra packages will be installed:
libpq-dev Suggested packages: postgresql-doc-10 The following NEW packages will be installed: libpq-dev postgresql-server-dev-9.5

In your's case

sudo apt-get install postgresql-server-dev-X.Y
sudo apt-get install python-psycopg2

I'm pretty sure you shouldn't need to set a position:

$("#dialog").dialog();

should center by default.

I did have a look at the article, and also checked what it says on the official jquery-ui site about positioning a dialog : and in it were discussed 2 states of: initialise and after initialise.

Code examples - (taken from jQuery UI 2009-12-03)

Initialize a dialog with the position option specified.

$('.selector').dialog({ position: 'top' });

Get or set the position option, after init.

//getter
var position = $('.selector').dialog('option', 'position');
//setter
$('.selector').dialog('option', 'position', 'top');

I think that if you were to remove the position attribute you would find it centers by itself else try the second setter option where you define 3 elements of "option" "position" and "center".

On OSX use fn instead of shift.

Should be able to do something like this also:

Select (id :> VARCHAR(10)) as converted__id_int

From Overview of Numeric Types;

BIT[(M)]

A bit-field type. M indicates the number of bits per value, from 1 to 64. The default is 1 if M is omitted.

This data type was added in MySQL 5.0.3 for MyISAM, and extended in 5.0.5 to MEMORY, InnoDB, BDB, and NDBCLUSTER. Before 5.0.3, BIT is a synonym for TINYINT(1).

TINYINT[(M)] [UNSIGNED] [ZEROFILL]

A very small integer. The signed range is -128 to 127. The unsigned range is 0 to 255.

Additionally consider this;

BOOL, BOOLEAN

These types are synonyms for TINYINT(1). A value of zero is considered false. Non-zero values are considered true.

CREATE PROCEDURE [dbo].[sp_Myforeach_Date]
    -- Add the parameters for the stored procedure here
    @SatrtDate as DateTime,
    @EndDate as dateTime,
    @DatePart as varchar(2),
    @OutPutFormat as int 
AS
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    Declare @DateList Table
    (Date varchar(50))

    WHILE @SatrtDate<= @EndDate
    BEGIN
    INSERT @DateList (Date) values(Convert(varchar,@SatrtDate,@OutPutFormat))
    IF Upper(@DatePart)='DD'
    SET @SatrtDate= DateAdd(dd,1,@SatrtDate)
    IF Upper(@DatePart)='MM'
    SET @SatrtDate= DateAdd(mm,1,@SatrtDate)
    IF Upper(@DatePart)='YY'
    SET @SatrtDate= DateAdd(yy,1,@SatrtDate)
    END 
    SELECT * FROM @DateList
END

Just put this Code and call the SP in This way

exec sp_Myforeach_Date @SatrtDate='03 Jan 2010',@EndDate='03 Mar 2010',@DatePart='dd',@OutPutFormat=106

Static constructor called only the first instance of the class created.

like this:

static class YourClass
{
    static YourClass()
    {
        //initialization
    }
}

Please note that, the repeatable in repeatable read regards to a tuple, but not to the entire table. In ANSC isolation levels, phantom read anomaly can occur, which means read a table with the same where clause twice may return different return different result sets. Literally, it's not repeatable.

Generally speaking:

all and any are functions that take some iterable and return True, if

• in the case of all(), no values in the iterable are falsy;
• in the case of any(), at least one value is truthy.

A value x is falsy iff bool(x) == False. A value x is truthy iff bool(x) == True.

Any non-booleans in the iterable will be fine — bool(x) will coerce any x according to these rules: 0, 0.0, None, [], (), [], set(), and other empty collections will yield False, anything else True. The docstring for bool uses the terms 'true'/'false' for 'truthy'/'falsy', and True/False for the concrete boolean values.

In your specific code samples:

You misunderstood a little bit how these functions work. Hence, the following does something completely not what you thought:

if any(foobars) == big_foobar:

...because any(foobars) would first be evaluated to either True or False, and then that boolean value would be compared to big_foobar, which generally always gives you False (unless big_foobar coincidentally happened to be the same boolean value).

Note: the iterable can be a list, but it can also be a generator/generator expression (˜ lazily evaluated/generated list) or any other iterator.

What you want instead is:

if any(x == big_foobar for x in foobars):

which basically first constructs an iterable that yields a sequence of booleans—for each item in foobars, it compares the item to big_foobar and emits the resulting boolean into the resulting sequence:

tmp = (x == big_foobar for x in foobars)

then any walks over all items in tmp and returns True as soon as it finds the first truthy element. It's as if you did the following:

In [1]: foobars = ['big', 'small', 'medium', 'nice', 'ugly']                                        

In [2]: big_foobar = 'big'                                                                          

In [3]: any(['big' == big_foobar, 'small' == big_foobar, 'medium' == big_foobar, 'nice' == big_foobar, 'ugly' == big_foobar])        
Out[3]: True

Note: As DSM pointed out, any(x == y for x in xs) is equivalent to y in xs but the latter is more readable, quicker to write and runs faster.

Some examples:

In [1]: any(x > 5 for x in range(4))
Out[1]: False

In [2]: all(isinstance(x, int) for x in range(10))
Out[2]: True

In [3]: any(x == 'Erik' for x in ['Erik', 'John', 'Jane', 'Jim'])
Out[3]: True

In [4]: all([True, True, True, False, True])
Out[4]: False

Never ever extend Object.prototype.

Horrible things will happen to your code. Things will break. You're extending all object types, including object literals.

Here's a quick example you can try:

    // Extend Object.prototype
Object.prototype.extended = "I'm everywhere!";

    // See the result
alert( {}.extended );          // "I'm everywhere!"
alert( [].extended );          // "I'm everywhere!"
alert( new Date().extended );  // "I'm everywhere!"
alert( 3..extended );          // "I'm everywhere!"
alert( true.extended );        // "I'm everywhere!"
alert( "here?".extended );     // "I'm everywhere!"

Instead create a function that you pass the object.

Object.filter = function( obj, predicate) {
    let result = {}, key;

    for (key in obj) {
        if (obj.hasOwnProperty(key) && !predicate(obj[key])) {
            result[key] = obj[key];
        }
    }

    return result;
};

I agree css is better. If you did want to do it via Xpath you could try:

    String kk = wd.findElement(By.xpath(.//*div[@id='customSelect_3']/div/span[@class='selectLabel clear'].getText()))

As I tussled with this, TryParse in 3.5 does have NumberStyles: The following code should also do the trick without Regex to ignore thousands seperator.

double.TryParse(length, NumberStyles.AllowDecimalPoint,CultureInfo.CurrentUICulture, out lengthD))

Not relevant to the original question asked but confirming that TryParse() indeed is a good option.

If you want to duplicate the table with all its constraints & keys follows this below steps:

1. Open the database in SQL Management Studio.
2. Right-click on the table that you want to duplicate.
3. Select Script Table as -> Create to -> New Query Editor Window. This will generate a script to recreate the table in a new query window.
4. Change the table name and relative keys & constraints in the script.
5. Execute the script.

Then for copying the data run this below script:

SET IDENTITY_INSERT DuplicateTable ON

INSERT Into DuplicateTable ([Column1], [Column2], [Column3], [Column4],... ) 
SELECT [Column1], [Column2], [Column3], [Column4],... FROM MainTable

SET IDENTITY_INSERT DuplicateTable OFF

In my case was webpack having the UglifyPlugin running with drop_console: true set

In Servers view double-click on Tomcat and change HTTP port in Ports section to something else. Or in Package Explorer navigate to Servers Tomcat and change Connector port part inside server.xml file.

Putting a @ in front of a string enables you to use special characters such as a backslash or double-quotes without having to use special codes or escape characters.

So you can write:

string path = @"C:\My path\";

instead of:

string path = "C:\\My path\\";

The JQuery code is fine. You must execute in the ready handler not in the window load event.

<script type="text/javascript">
$(function(){
  var aspForm  = $("form#aspnetForm");
  var firstInput = $(":input:not(input[type=button],input[type=submit],button):visible:first", aspForm);
  firstInput.focus();
});
</script>

Update

I tried with the example of Karim79(thanks for the example) and it works fine: http://jsfiddle.net/2sMfU/

Depends in how you are hiding your div, diplay=none is different of visibility=hidden and the opacity=0

• Visibility then use ...style.visibility='visible'

• Display then use ...style.display='block' (or others depends how
  you setup ur css, inline, inline-block, flex...)

• Opacity then use ...style.opacity='1';

To center a div, set it's width to some value and add margin: auto.

#partners .wrap {
    width: 655px;
    margin: auto;
}

EDIT, you want to center the div contents, not the div itself. You need to change display property of h2, ul and li to inline, and remove the float: left.

#partners li, ul, h2 {
    display: inline;
    float: none;
}

Then, they will be layed out like normal text elements, and aligned according to text-align property of their container, which is what you want.

You need to change from queue import Queue to from multiprocessing import Queue.

The root reason is the former Queue is designed for threading module Queue while the latter is for multiprocessing.Process module.

For details, you can read some source code or contact me!

I have created multiple targets before I ever used pods. Later when I started to compile the other targets I had to add link_with with the list of targets in my Podfile.

Well maybe you forgot to add "$route" when declaring the dependencies of your Controller:

app.controller('NameCtrl', ['$scope','$route', function($scope,$route) {   
   // $route.reload(); Then this should work fine.
}]);

Unfortunately, validator.resetForm() does NOT work, in many cases.

I have a case where, if someone hits the "Submit" on a form with blank values, it should ignore the "Submit." No errors. That's easy enough. If someone puts in a partial set of values, and hits "Submit," it should flag some of the fields with errors. If, however, they wipe out those values and hit "Submit" again, it should clear the errors. In this case, for some reason, there are no elements in the "currentElements" array within the validator, so executing .resetForm() does absolutely nothing.

There are bugs posted on this.

Until such time as they fix them, you need to use Nick Craver's answer, NOT Parrots' accepted answer.

To convert an integer to a float in Python you can use the following:

float_version = float(int_version)

The reason you are getting 0 is that Python 2 returns an integer if the mathematical operation (here a division) is between two integers. So while the division of 144 by 314 is 0.45~~~, Python converts this to integer and returns just the 0 by eliminating all numbers after the decimal point.

Alternatively you can convert one of the numbers in any operation to a float since an operation between a float and an integer would return a float. In your case you could write float(144)/314 or 144/float(314). Another, less generic code, is to say 144.0/314. Here 144.0 is a float so it’s the same thing.

Query for the last weeks:

SELECT *

If you are using a lot of memory and facing memory leaks, then you might want to check if you are using a large number of ArrayLists or HashMaps with many elements each.

An ArrayList is implemented as a dynamic array. The source code from Sun/Oracle shows that when a new element is inserted into a full ArrayList, a new array of 1.5 times the size of the original array is created, and the elements copied over. What this means is that you could be wasting up to 50% of the space in each ArrayList you use, unless you call its trimToSize method. Or better still, if you know the number of elements you are going to insert before hand, then call the constructor with the initial capacity as its argument.

I did not examine the source code for HashMap very carefully, but at a first glance it appears that the array length in each HashMap must be a power of two, making it another implementation of a dynamic array. Note that HashSet is essentially a wrapper around HashMap.

I think it is telling you exactly what is wrong. You cannot compare an integer with a varchar. PostgreSQL is strict and does not do any magic typecasting for you. I'm guessing SQLServer does typecasting automagically (which is a bad thing).

If you want to compare these two different beasts, you will have to cast one to the other using the casting syntax ::.

Something along these lines:

create view view1
as 
select table1.col1,table2.col1,table3.col3
from table1 
inner join
table2 
inner join 
table3
on 
table1.col4::varchar = table2.col5
/* Here col4 of table1 is of "integer" type and col5 of table2 is of type "varchar" */
/* ERROR: operator does not exist: integer = character varying */
....;

Notice the varchar typecasting on the table1.col4.

Also note that typecasting might possibly render your index on that column unusable and has a performance penalty, which is pretty bad. An even better solution would be to see if you can permanently change one of the two column types to match the other one. Literately change your database design.

Or you could create a index on the casted values by using a custom, immutable function which casts the values on the column. But this too may prove suboptimal (but better than live casting).

whoever is checking this post in 2020, they can use <input inputmode="tel"> for phone numbers (10 digit), <input inputmode="numeric" maxLength={5}> for numeric type and restrict to only 5 digits.

You can create a custom alertDialog and use a xml layout. in the layout, you can set the background color and textcolor.

Something like this:

Dialog dialog = new Dialog(this, android.R.style.Theme_Translucent_NoTitleBar);
LayoutInflater inflater = (LayoutInflater)ActivityName.this.getSystemService(LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.custom_layout,(ViewGroup)findViewById(R.id.layout_root));
dialog.setContentView(view);

Just two different ways of doing the same thing. It may be a historical reason (can't remember if one came before the other).

You might want to try this example for version 2.6 of Python.

def my_print(text, begin, end):
    "Print text in UPPER between 'begin' and 'end' in lower."
    for obj in (text, begin, end):
        assert isinstance(obj, str), 'Argument of wrong type!'
    print begin.lower() + text.upper() + end.lower()

However, have you considered letting the function fail naturally instead?

It depends on what you're looking for.

With adjacency matrices you can answer fast to questions regarding if a specific edge between two vertices belongs to the graph, and you can also have quick insertions and deletions of edges. The downside is that you have to use excessive space, especially for graphs with many vertices, which is very inefficient especially if your graph is sparse.

On the other hand, with adjacency lists it is harder to check whether a given edge is in a graph, because you have to search through the appropriate list to find the edge, but they are more space efficient.

Generally though, adjacency lists are the right data structure for most applications of graphs.

Because constructors are an implementation detail - they're not something that a user of an interface/superclass can actually invoke at all. By the time they get an instance, it's already been constructed; and vice-versa, at the time you construct an object there's by definition no variable it's currently assigned to.

Think about what it would mean to force all subclasses to have an inherited constructor. I argue it's clearer to pass the variables in directly than for the class to "magically" have a constructor with a certain number of arguments just because it's parent does.

It will also be empty if the new Referrer Policy standard draft is used to prevent that the referer header is sent to the request origin. Example:

<meta name="referrer" content="none">

Although Chrome and Firefox have already implemented a draft version of the Referrer Policy, you should be careful with it because for example Chrome expects no-referrer instead of none (and I have seen also never somewhere).

As a side note, you can include the separators while splitting the string in Go. To do so, use strings.SplitAfter as in the example below.

package main

import (
    "fmt"
    "strings"
)

func main() {
    fmt.Printf("%q\n", strings.SplitAfter("z,o,r,r,o", ","))
}

Action normally specifies the file/page that the form is submitted to (using the method described in the method paramater (post, get etc.))

An action of # indicates that the form stays on the same page, simply suffixing the url with a #. Similar use occurs in anchors. <a href=#">Link</a> for example, will stay on the same page.

Thus, the form is submitted to the same page, which then processes the data etc.

R has a number of (undocumented) convenience functions for converting factors:

• as.character.factor
• as.data.frame.factor
• as.Date.factor
• as.list.factor
• as.vector.factor
• ...

But annoyingly, there is nothing to handle the factor -> numeric conversion. As an extension of Joshua Ulrich's answer, I would suggest to overcome this omission with the definition of your own idiomatic function:

as.numeric.factor <- function(x) {as.numeric(levels(x))[x]}

that you can store at the beginning of your script, or even better in your .Rprofile file.

=RIGHT(A1,LEN(A1)-FIND("`*`",SUBSTITUTE(A1," ","`*`",LEN(A1)-LEN(SUBSTITUTE(A1," ",""))))) 

This is what worked for me:

$.get({
    method: 'GET',
    url: 'api.php',
    headers: {
        'Content-Type': 'application/json',
    },
    // query parameters go under "data" as an Object
    data: {
        client: 'mikescafe'
    }
});

will make a REST/AJAX call - > GET http://localhost:3000/api.php?client=mikescafe

Good Luck.

Swift 4.2 - No Delegate Needed

You can create an action outlet from the UITextField for the "Primary Action Triggered" and resign first responder on the sender parameter passed in:

@IBAction func done(_ sender: UITextField) {
    sender.resignFirstResponder()
}

Super simple.

Another method using jquery

    <script type="text/javascript">

    //set this variable according to the need within the page
    var BACKSPACE_NAV_DISABLED = true;

    function fnPreventBackspace(event){if (BACKSPACE_NAV_DISABLED && event.keyCode == 8) {return false;}}
    function fnPreventBackspacePropagation(event){if(BACKSPACE_NAV_DISABLED && event.keyCode == 8){event.stopPropagation();}return true;}

    $(document).ready(function(){ 
        if(BACKSPACE_NAV_DISABLED){
            //for IE use keydown, for Mozilla keypress  
            //as described in scr: http://www.codeproject.com/KB/scripting/PreventDropdownBackSpace.aspx
            $(document).keypress(fnPreventBackspace);
            $(document).keydown(fnPreventBackspace);

            //Allow Backspace is the following controls 
            var jCtrl = null;
            jCtrl = $('input[type="text"]');
            jCtrl.keypress(fnPreventBackspacePropagation);
            jCtrl.keydown(fnPreventBackspacePropagation);

            jCtrl = $('input[type="password"]');
            jCtrl.keypress(fnPreventBackspacePropagation);
            jCtrl.keydown(fnPreventBackspacePropagation);

            jCtrl = $('textarea');
            jCtrl.keypress(fnPreventBackspacePropagation);
            jCtrl.keydown(fnPreventBackspacePropagation);

            //disable backspace for readonly and disabled
            jCtrl = $('input[type="text"][readonly="readonly"]')
            jCtrl.keypress(fnPreventBackspace);
            jCtrl.keydown(fnPreventBackspace);

            jCtrl = $('input[type="text"][disabled="disabled"]')
            jCtrl.keypress(fnPreventBackspace);
            jCtrl.keydown(fnPreventBackspace);
        }
    });

In eclipse click file then select switch workspace then browse and select another folder. Now repeat the same process and this time there will be no error :)

This error message means that Windows isn't able to find "cygwin1.dll". The Programs that the Cygwin gcc create depend on this DLL. The file is part of cygwin , so most likely it's located in C:\cygwin\bin. To fix the problem all you have to do is add C:\cygwin\bin (or the location where cygwin1.dll can be found) to your system path. Alternatively you can copy cygwin1.dll into your Windows directory.

There is a nice tool called DependencyWalker that you can download from http://www.dependencywalker.com . You can use it to check dependencies of executables, so if you inspect your generated program it tells you which dependencies are missing and which are resolved.

Here are the most common reasons

• Incorrect file paths

• File names are misspelled

• Wrong file extension

• Files are missing

• The read permission has not been set for the image(s)

Note: On *nix systems, consider using the following command to add read permission for an image:

chmod o+r imagedirectoryAddress/imageName.extension

or this command to add read permission for all images:

chmod o+r imagedirectoryAddress/*.extension

I had a similar issue, but more complex as I needed to transform a CSV file into an array of arrays (each line is one array element that inside has an array of items split by comma).

The easiest solution (and more secure I bet) was to use PapaParse which has a "no-header" option that transform the CSV file into an array of arrays, plus, it automatically detected the "," as my delimiter.

Plus, it is registered in Bower, so I only had to:

bower install papa-parse --save

And then use it in my code as follows:

var arrayOfArrays = Papa.parse(csvStringWithEnters), {header:false}).data;

I really liked it.

In 1.0, the functionality was bound to ( and tab and shift-tab, in 2.0 tab was deprecated but still functional in some unambiguous cases completing or inspecting were competing in many cases. Recommendation was to always use shift-Tab. ( was also added as deprecated as confusing in Haskell-like syntax to also push people toward Shift-Tab as it works in more cases. in 3.0 the deprecated bindings have been remove in favor of the official, present for 18+ month now Shift-Tab.

So press Shift-Tab.

now, for dplyr, adding a distinct counter.

df %>%
    group_by(aa, bb) %>%
    summarise(first=head(value,1), count=n_distinct(value))

You create groups, them summarise within groups.

If data is numeric, you can use:
first(value) [there is also last(value)] in place of head(value, 1)

see: http://cran.rstudio.com/web/packages/dplyr/vignettes/introduction.html

Full:

> df
Source: local data frame [16 x 3]

   aa bb value
1   1  1   GUT
2   1  1   PER

Another way of adding schema dynamically or if you want to change it to something else

DECLARE @schema AS VARCHAR(256) = 'dbo.'
--User can also use SELECT SCHEMA_NAME() to get the default schema name


DECLARE @ID INT

declare @SQL nvarchar(max) = 'EXEC ' + @schema +'spSelectCaseBookingDetails @BookingID = '  + CAST(@ID AS NVARCHAR(10))

No need to cast @ID if it is nvarchar or varchar

execute (@SQL)

If you normalize your data first, then you can avoid all the very complex regular expressions required to validate phone numbers. From my experience, complicated regex patterns can have two unwanted side effects: (1) they can have unexpected behavior that would be a pain to debug later, and (2) they can be slower than simpler regex patterns, which may become noticeable when you are executing regex in a loop.

By keeping your regular expressions as simple as possible, you reduce these risks and your code will be easier for others to follow, partly because it will be more predictable. To use your phone number example, first we can normalize the value by stripping out all non-digits like this:

value = $.trim(value).replace(/\D/g, '');

Now your regex pattern for a US phone number (or any other locale) can be much simpler:

/^1?\d{10}$/

Not only is the regular expression much simpler, it is also easier to follow what's going on: a value optionally leading with number one (US country code) followed by ten digits. If you want to format the validated value to make it look pretty, then you can use this slightly longer regex pattern:

/^1?(\d{3})(\d{3})(\d{4})$/

This means an optional leading number one followed by three digits, another three digits, and ending with four digits. With each group of numbers memorized, you can output it any way you want. Here's a codepen using jQuery Validation to illustrate this for two locales (Singapore and US):

http://codepen.io/thdoan/pen/MaMqvZ

In your setup.py, if you have:

from distutils.core import setup

Then, change it to

from setuptools import setup

Then re-create your virtualenv and re-run the command, and it should work.

Please try this.

// Find out what the map's zoom level is
zoom = map.getZoom();
if (zoom == 1) {
  // If the zoom level is that low, means it's looking around the
world.
  // Swap the sw and ne coords
  viewportBounds = new
google.maps.LatLngBounds(results[0].geometry.location, initialLatLng);
  map.fitBounds(viewportBounds);
}

If this will helpful to you.

All the best

I came up with my own basic method which seems to work fine (so far). There's probably a dozen things some of the popular scripts address that I haven't thought of.

Note - This solution is fast and easy to implement but of course not great for performance. Definitely look into the new Intersection Observer as mentioned by Apoorv and explained by developers.google if performance is an issue.

The JQuery

$(window).scroll(function() {
    $.each($('img'), function() {
        if ( $(this).attr('data-src') && $(this).offset().top < ($(window).scrollTop() + $(window).height() + 100) ) {
            var source = $(this).data('src');
            $(this).attr('src', source);
            $(this).removeAttr('data-src');
        }
    })
})

Sample html code

<div>
    <img src="" data-src="pathtoyour/image1.jpg">
    <img src="" data-src="pathtoyour/image2.jpg">
    <img src="" data-src="pathtoyour/image3.jpg">
</div>

Explained

When the page is scrolled each image on the page is checked..

$(this).attr('data-src') - if the image has the attribute data-src

and how far those images are from the bottom of the window..

$(this).offset().top < ($(window).scrollTop() + $(window).height() + 100)

adjust the + 100 to whatever you like (- 100 for example)

var source = $(this).data('src'); - gets the value of data-src= aka the image url

$(this).attr('src', source); - puts that value into the src=

$(this).removeAttr('data-src'); - removes the data-src attribute (so your browser doesn't waste resources messing with the images that have already loaded)

Adding To Existing Code

To convert your html, in an editor just search and replace src=" with src="" data-src="

UPDATE t1
INNER JOIN t2 ON t2.t1_id = t1.id
INNER JOIN t3 ON t2.t3_id = t3.id
SET t1.a = 'something',
    t2.b = 42,
    t3.c = t2.c
WHERE t1.a = 'blah';

To see what this is going to update, you can convert this into a select statement, e.g.:

SELECT t2.t1_id, t2.t3_id, t1.a, t2.b, t2.c AS t2_c, t3.c AS t3_c
FROM t1
INNER JOIN t2 ON t2.t1_id = t1.id
INNER JOIN t3 ON t2.t3_id = t3.id
WHERE t1.a = 'blah';

An example using the same tables as the other answer:

SELECT Books.BookID, Orders.OrderID,
    Orders.Quantity AS CurrentQuantity,
    Orders.Quantity + 2 AS NewQuantity,
    Books.InStock AS CurrentStock,
    Books.InStock - 2 AS NewStock
FROM Books
INNER JOIN Orders ON Books.BookID = Orders.BookID
WHERE Orders.OrderID = 1002;

UPDATE Books
INNER JOIN Orders ON Books.BookID = Orders.BookID
SET Orders.Quantity = Orders.Quantity + 2,
    Books.InStock = Books.InStock - 2
WHERE Orders.OrderID = 1002;

EDIT:

Just for fun, let's add something a bit more interesting.

Let's say you have a table of books and a table of authors. Your books have an author_id. But when the database was originally created, no foreign key constraints were set up and later a bug in the front-end code caused some books to be added with invalid author_ids. As a DBA you don't want to have to go through all of these books to check what the author_id should be, so the decision is made that the data capturers will fix the books to point to the right authors. But there are too many books to go through each one and let's say you know that the ones that have an author_id that corresponds with an actual author are correct. It's just the ones that have nonexistent author_ids that are invalid. There is already an interface for the users to update the book details and the developers don't want to change that just for this problem. But the existing interface does an INNER JOIN authors, so all of the books with invalid authors are excluded.

What you can do is this: Insert a fake author record like "Unknown author". Then update the author_id of all the bad records to point to the Unknown author. Then the data capturers can search for all books with the author set to "Unknown author", look up the correct author and fix them.

How do you update all of the bad records to point to the Unknown author? Like this (assuming the Unknown author's author_id is 99999):

UPDATE books
LEFT OUTER JOIN authors ON books.author_id = authors.id
SET books.author_id = 99999
WHERE authors.id IS NULL;

The above will also update books that have a NULL author_id to the Unknown author. If you don't want that, of course you can add AND books.author_id IS NOT NULL.

Using python-dateutil:

In [1]: import dateutil.parser as dparser

In [18]: dparser.parse("monkey 2010-07-10 love banana",fuzzy=True)
Out[18]: datetime.datetime(2010, 7, 10, 0, 0)

Invalid dates raise a ValueError:

In [19]: dparser.parse("monkey 2010-07-32 love banana",fuzzy=True)
# ValueError: day is out of range for month

It can recognize dates in many formats:

In [20]: dparser.parse("monkey 20/01/1980 love banana",fuzzy=True)
Out[20]: datetime.datetime(1980, 1, 20, 0, 0)

Note that it makes a guess if the date is ambiguous:

In [23]: dparser.parse("monkey 10/01/1980 love banana",fuzzy=True)
Out[23]: datetime.datetime(1980, 10, 1, 0, 0)

But the way it parses ambiguous dates is customizable:

In [21]: dparser.parse("monkey 10/01/1980 love banana",fuzzy=True, dayfirst=True)
Out[21]: datetime.datetime(1980, 1, 10, 0, 0)

Change your code to

document.write("<td width='74'><button id='button' type='button' onclick='myfunction(\""+ name + "\")'>click</button></td>")

when new props or states being received (like you call setState here), React will invoked some functions, which are called componentWillUpdate and componentDidUpdate

in your case, just simply add a componentDidUpdate function to call this.drawGrid()

here is working code in JS Bin

as I mentioned, in the code, componentDidUpdate will be invoked after this.setState(...)

then componentDidUpdate inside is going to call this.drawGrid()

I would advise, it is slightly better practise to use string model references for ForeignKey relationships if utilising an app based approach to seperation of logical concerns .

So, expanding on Martijn Pieters' answer:

class Person(models.Model):
    name = models.CharField(max_length=50)
    birthday = models.DateField()
    anniversary = models.ForeignKey(
        'app_label.Anniversary', on_delete=models.CASCADE)
    address = models.ForeignKey(
        'app_label.Address', on_delete=models.CASCADE)

class Address(models.Model):
    line1 = models.CharField(max_length=150)
    line2 = models.CharField(max_length=150)
    postalcode = models.CharField(max_length=10)
    city = models.CharField(max_length=150)
    country = models.CharField(max_length=150)

class Anniversary(models.Model):
    date = models.DateField()

You can use the below code to print all column names; You can also modify the code to print other details in whichever format u like

    declare @Result varchar(max)='
            '
            select @Result=@Result+''+ColumnName+'
            '
            from
            (
                select
                    replace(col.name, ' ', '_') ColumnName,
                    column_id ColumnId
                from sys.columns col
                    join sys.types typ on
                        col.system_type_id = typ.system_type_id AND col.user_type_id = typ.user_type_id
                where object_id = object_id('tblPracticeTestSections')
            ) t
            order by ColumnId
            print @Result

Output

column1
column2
column3
column4

To use the same code to print the table and its column name as C# class use the below code:

    declare @TableName sysname = '<EnterTableName>'
    declare @Result varchar(max) = 'public class ' + @TableName + '
    {'

    select @Result = @Result + '
        public static string ' + ColumnName + ' { get { return "'+ColumnName+'"; } }
    '
    from
    (
        select
            replace(col.name, ' ', '_') ColumnName,
            column_id ColumnId
        from sys.columns col
            join sys.types typ on
                col.system_type_id = typ.system_type_id AND col.user_type_id = typ.user_type_id
        where object_id = object_id(@TableName)
    ) t
    order by ColumnId

    set @Result = @Result  + '
    }'

    print @Result

Output:

 public class tblPracticeTestSections
 {
   public static string column1 { get { return "column1"; } }

   public static string column2{ get { return "column2"; } }

   public static string column3{ get { return "column3"; } }

   public static string column4{ get { return "column4"; } }

 } 

Using a table would be one (and easy) option.

Other options are all about setting fixed width on the and making it text-aligned to the right:

label {
   width: 200px;
   display: inline-block;
   text-align: right;
}

or, as was pointed out, make them all float instead of inline.

This method can be helpful.

def avg(arr)
  val = 0.0

  arr.each do |n|
    val += n
  end

  len = arr.length

  val / len 
end

p avg([0,4,8,2,5,0,2,6])

This link says it better than I could and helped in my decision making. I usually opt for an int as a primary key, unless I have a specific need not to and I also let SQL server auto-generate/maintain this field unless I have some specific reason not to. In reality, performance concerns need to be determined based on your specific app. There are many factors at play here including but not limited to expected db size, proper indexing, efficient querying, and more. Although people may disagree, I think in many scenarios you will not notice a difference with either option and you should choose what is more appropriate for your app and what allows you to develop easier, quicker, and more effectively (If you never complete the app what difference does the rest make :).

P.S. I'm not sure why you would use a Composite PK or what benefit you believe that would give you.

I would like to add an updated answer - now I have been using git for a while, I find that I am often using the following commands to do any pushing (using the original question as the example):

• git push origin amd_qlp_tester - push to the branch located in the remote called origin on remote-branch called amd_qlp_tester.
• git push -u origin amd_qlp_tester - same as last one, but sets the upstream linking the local branch to the remote branch so that next time you can just use git push/pull if not already linked (only need to do it once).
• git push - Once you have set the upstream you can just use this shorter version.

Note -u option is the short version of --set-upstream - they are the same.

maybe SSL

    @Override
    public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
        // ignore ssl error
        if (handler != null){
            handler.proceed();
        } else {
            super.onReceivedSslError(view, null, error);
        }
    }

The savedInstanceState is only for saving state associated with a current instance of an Activity, for example current navigation or selection info, so that if Android destroys and recreates an Activity, it can come back as it was before. See the documentation for onCreate and onSaveInstanceState

For more long lived state, consider using a SQLite database, a file, or preferences. See Saving Persistent State.

Try the WSDL To Proxy class tool shipped with the .NET Framework SDK. I've never used it before, but it certainly looks like what you need.

You can use a simple cast:

DateTime dtValue = (DateTime) dtNullAbleSource;

As Leandro Tupone said, you have to check if the var is null before

I usually do this and works always.

/try this/

for (i = res; i < *size-1; i++) { 

    arrb[i] = arrb[i + 1];
}

*size = *size - 1; /*in some ides size -- could give problems*/

Jon Skeet is correct. Here is the Nul Device Driver page in the Windows Embedded documentation (I have no idea why it's not somewhere else...).

Here is another:

• The null device in the registry
• Special file names
• More on file naming

App.Config is an XML file that is used as a configuration file for your application. In other words, you store inside it any setting that you may want to change without having to change code (and recompiling). It is often used to store connection strings.

See this MSDN article on how to do that.

SOLVED: Always be sure to update your Xcode folks!

Protip: And don't do it from the apple store (but always do it from an official apple website of course)

tip from: http://ericasadun.com/2016/03/22/xcode-upgrades-lessons-learned/

official apple download page: https://developer.apple.com/download/more/

For those who are unable to resolve with above method

1. Go to project settings in Xcode. Menu File->Project Settings

2. Go to per-User Project Settings section.

3. Click on advanced.

4. Select Xcode Default option. previously this used to be Legacy for my project.

I have analysed on similar lines and concluded that clean is causing the archive to fail. So, the new build system is not clearing the custom/legacy build directory.

delete the build/ folder in ios/ and rerun if that doesn't do any change then
File -> Project Settings (or WorkSpace Settings) -> Build System -> Legacy Build System
Rerun and voilà!

If it still Fails you need to clean full project

Do the following:

• Delete ios dir manually
• Clean cache Run npm cache clean --force
• Run react-native eject
• Re-install all packages npm install
• Run the link command react-native link
• Finally run react-native run-ios

You should be using pip to install packages, since it gives you uninstall capabilities.

Also, look into virtualenv. It works well with pip and gives you a sandbox so you can explore new stuff without accidentally hosing your system-wide install.

Table should present with same structure in both dump and database.

`zgrep -a ^"INSERT INTO \`table_name" DbDump-backup.sql.tar.gz | mysql -u<user> -p<password> database_name`

or

`zgrep -a ^"INSERT INTO \`table_name" DbDump-backup.sql | mysql -u<user> -p<password> database_name`

You can use the from and size parameters to page through all your data. This could be very slow depending on your data and how much is in the index.

It's cleaner/safer to use the getters provided by google instead of accessing the properties like some did

google.maps.event.addListener(drawingManager, 'overlaycomplete', function(polygon) {
    var coordinatesArray = polygon.overlay.getPath().getArray();
});

There are more ways to kill a dog than hanging. ^[1]

awk '{key=$0; getline; print key ", " $0;}'

Put whatever delimiter you like inside the quotes.

Try this:

var request = WebRequest.Create("http://www.gravatar.com/avatar/6810d91caff032b202c50701dd3af745?d=identicon&r=PG");

using (var response = request.GetResponse())
using (var stream = response.GetResponseStream())
{
    pictureBox1.Image = Bitmap.FromStream(stream);
}

here are two samples: http://jsfiddle.net/H5q5h/1/

one uses float:left and a wrapper with overflow:hidden. the wrapper ensures the sibling of the wrapper starts below the wrapper.

the 2nd one uses the more recent display:inline-block and wrapper can be disregarded. but this is not generally supported by older browsers so tread lightly on this one. also, any white space between the items will cause an unnecessary "margin-like" white space on the left and right of the item divs.

Here's a complete solution for those using Imagick in PHP:

$im = new \Imagick($filePath);
$im->setImageCompression(\Imagick::COMPRESSION_JPEG);
$im->setImageCompressionQuality(85);
$im->stripImage();
$im->setInterlaceScheme(\Imagick::INTERLACE_PLANE);

// Try between 0 or 5 radius. If you find radius of 5 
// produces too blurry  pictures decrease to 0 until you 
// find a good balance between size and quality. 
$im->gaussianBlurImage(0.05, 5);



// Include this part if you also want to specify a maximum size for the images

$size = $im->getImageGeometry();
$maxWidth = 1920;
$maxHeight = 1080;


// ----------
// |        |
// ----------
if($size['width'] >= $size['height']){
  if($size['width'] > $maxWidth){
    $im->resizeImage($maxWidth, 0, \Imagick::FILTER_LANCZOS, 1);
  }
}


// ------
// |    |
// |    |
// |    |
// |    |
// ------
else{
  if($size['height'] > $maxHeight){
    $im->resizeImage(0, $maxHeight, \Imagick::FILTER_LANCZOS, 1);
  }
}

If you are doing this on a Windows system, you can use Plink (part of PuTTY).

plink your_username@yourhost -pw your_password

Your server tells you exactly what you need : [Hint: SSLProxyEngine]

You need to add that directive to your VirtualHost before the Proxy directives :

SSLProxyEngine on
ProxyPass /primary/store https://localhost:9763/store/
ProxyPassReverse /primary/store https://localhost:9763/store/

See the doc for more detail.

I tried all settings mentioned in this post to build my project successfully however that didn't work for me. At last I was able to build my project successfully with mvn -DargLine=-Dfile.encoding=UTF-8 clean insall command.

$(this).attr("id", "rnd" + $(this).attr("tag") + "_" + i.toString());

should be

$(this).attr("id", "rnd" + this.nodeName.toLowerCase() + "_" + i.toString());

In general, android:gravity="right" is different from android:layout_gravity="right".

The first one affects the position of the text itself within the View, so if you want it to be right-aligned, then layout_width= should be either "fill_parent" or "match_parent".

The second one affects the View's position inside its parent, in other words - aligning the object itself (edit box or text view) inside the parent view.

I think you might want:

String encodedFile = Base64.getEncoder().encodeToString(bytes);

It's easy, you should set server http response header first. The problem is not with your front-end javascript code. You need to return this header:

Access-Control-Allow-Origin:*

or

Access-Control-Allow-Origin:your domain

In Apache config files, the code is like this:

Header set Access-Control-Allow-Origin "*"

In nodejs,the code is like this:

res.setHeader('Access-Control-Allow-Origin','*');

Not mentioned above. You could also crate a DateTime object by providing a timestamp as string in the constructor with a leading @ sign.

$dt = new DateTime('@123456789');
$dt->setTimezone(new DateTimeZone('America/New_York'));
echo $dt->format('F j, Y - G:i');

See the documentation about compound formats: https://www.php.net/manual/en/datetime.formats.compound.php

for i in $(ls); do cp -r "$i" "$i"_dev; done;

I know this an old question but I was searching for the same thing for C and I figured it out so I figured I'd post it if someone else is searching for a way in C:

char proper(char string[]){  

int i = 0;

for(i=0; i<=25; i++)
{
    string[i] = tolower(string[i]);  //converts all character to lower case
    if(string[i-1] == ' ') //if character before is a space 
    {
        string[i] = toupper(string[i]); //converts characters after spaces to upper case
    }

}
    string[0] = toupper(string[0]); //converts first character to upper case


    return 0;
}

No, there is no way to only set the opacity of a border with css.

For example, if you did not know the color, there is no way to only change the opacity of the border by simply using rgba().

There are several problems here, so I'll start with my usual high-level advice: Start small and simple, add complexity a little at a time, test at every step, and never add to code that doesn't work. (I really ought to have that hotkeyed.)

You're mixing Make syntax and shell syntax in a way that is just dizzying. You should never have let it get this big without testing. Let's start from the outside and work inward.

UNAME := $(shell uname -m)

all:
    $(info Checking if custom header is needed)
    ifeq ($(UNAME), x86_64)
    ... do some things to build unistd_32.h
    endif

    @make -C $(KDIR) M=$(PWD) modules

So you want unistd_32.h built (maybe) before you invoke the second make, you can make it a prerequisite. And since you want that only in a certain case, you can put it in a conditional:

ifeq ($(UNAME), x86_64)
all: unistd_32.h
endif

all:
    @make -C $(KDIR) M=$(PWD) modules

unistd_32.h:
    ... do some things to build unistd_32.h

Now for building unistd_32.h:

F1_EXISTS=$(shell [ -e /usr/include/asm/unistd_32.h ] && echo 1 || echo 0 )
ifeq ($(F1_EXISTS), 1)
    $(info Copying custom header)
    $(shell sed -e 's/__NR_/__NR32_/g' /usr/include/asm/unistd_32.h > unistd_32.h)
else    
    F2_EXISTS=$(shell [[ -e /usr/include/asm-i386/unistd.h ]] && echo 1 || echo 0 )
    ifeq ($(F2_EXISTS), 1)
        $(info Copying custom header)
        $(shell sed -e 's/__NR_/__NR32_/g' /usr/include/asm-i386/unistd.h > unistd_32.h)
    else
        $(error asm/unistd_32.h and asm-386/unistd.h does not exist)
    endif
endif

You are trying to build unistd.h from unistd_32.h; the only trick is that unistd_32.h could be in either of two places. The simplest way to clean this up is to use a vpath directive:

vpath unistd.h /usr/include/asm /usr/include/asm-i386

unistd_32.h: unistd.h
    sed -e 's/__NR_/__NR32_/g' $< > $@

public void setHoursWorked(){
    hoursWorked = hours;
}

You haven't defined hours inside that method. hours is not passed in as a parameter, it's not declared as a variable, and it's not being used as a class member, so you get that error.

You could use the ceiling function; this portion of SQL code :

select ceiling(45.01), ceiling(45.49), ceiling(45.99);

will get you "46" each time.

For your update, so, I'd say :

Update product SET price = ceiling(45.01)

BTW : On MySQL, ceil is an alias to ceiling ; not sure about other DB systems, so you might have to use one or the other, depending on the DB you are using...

Quoting the documentation :

CEILING(X)

Returns the smallest integer value not less than X.

And the given example :

mysql> SELECT CEILING(1.23);
        -> 2
mysql> SELECT CEILING(-1.23);
        -> -1

It prevents JSON hijacking, a major JSON security issue that is formally fixed in all major browsers since 2011 with ECMAScript 5.

Contrived example: say Google has a URL like mail.google.com/json?action=inbox which returns the first 50 messages of your inbox in JSON format. Evil websites on other domains can't make AJAX requests to get this data due to the same-origin policy, but they can include the URL via a <script> tag. The URL is visited with your cookies, and by overriding the global array constructor or accessor methods they can have a method called whenever an object (array or hash) attribute is set, allowing them to read the JSON content.

The while(1); or &&&BLAH&&& prevents this: an AJAX request at mail.google.com will have full access to the text content, and can strip it away. But a <script> tag insertion blindly executes the JavaScript without any processing, resulting in either an infinite loop or a syntax error.

This does not address the issue of cross-site request forgery.

Rules of thumb for C++11:

Pass by value, except when

1. you do not need ownership of the object and a simple alias will do, in which case you pass by const reference,
2. you must mutate the object, in which case, use pass by a non-const lvalue reference,
3. you pass objects of derived classes as base classes, in which case you need to pass by reference. (Use the previous rules to determine whether to pass by const reference or not.)

Passing by pointer is virtually never advised. Optional parameters are best expressed as a std::optional (boost::optional for older std libs), and aliasing is done fine by reference.

C++11's move semantics make passing and returning by value much more attractive even for complex objects.

Rules of thumb for C++03:

Pass arguments by const reference, except when

1. they are to be changed inside the function and such changes should be reflected outside, in which case you pass by non-const reference
2. the function should be callable without any argument, in which case you pass by pointer, so that users can pass NULL/0/nullptr instead; apply the previous rule to determine whether you should pass by a pointer to a const argument
3. they are of built-in types, which can be passed by copy
4. they are to be changed inside the function and such changes should not be reflected outside, in which case you can pass by copy (an alternative would be to pass according to the previous rules and make a copy inside of the function)

(here, "pass by value" is called "pass by copy", because passing by value always creates a copy in C++03)

There's more to this, but these few beginner's rules will get you quite far.

Use the following syntax:

  ALTER TABLE your_table
  MODIFY COLUMN column1 datatype,
  MODIFY COLUMN column2 datatype,
  ... ... ... ... ... 
  ... ... ... ... ...

Based on that, your ALTER command should be:

  ALTER TABLE webstore.Store
  MODIFY COLUMN ShortName VARCHAR(100),
  MODIFY COLUMN UrlShort VARCHAR(100)

Note that:

1. There are no second brackets around the MODIFY statements.
2. I used two separate MODIFY statements for two separate columns.

This is the standard format of the MODIFY statement for an ALTER command on multiple columns in a MySQL table.

Take a look at the following: http://dev.mysql.com/doc/refman/5.1/en/alter-table.html and Alter multiple columns in a single statement

To create a Windows Service from an executable, you can use sc.exe:

sc.exe create <new_service_name> binPath= "<path_to_the_service_executable>"

You must have quotation marks around the actual exe path, and a space after the binPath=.

More information on the sc command can be found in Microsoft KB251192.

Note that it will not work for just any executable: the executable must be a Windows Service (i.e. implement ServiceMain). When registering a non-service executable as a service, you'll get the following error upon trying to start the service:

Error 1053: The service did not respond to the start or control request in a timely fashion.

There are tools that can create a Windows Service from arbitrary, non-service executables, see the other answers for examples of such tools.

It's been more than 8 years, but maybe someone will find it helpful anyway. I was able to do the trick without rebase -i. The idea is to lead git to the same state it was before you did git commit:

# first rewind back (mind the dot,
# though it can be any valid path,
# for instance if you want to apply only a subset of the commit)
git reset --hard <previous-commit> .

# apply the changes
git checkout <commit-you-want-to-split>

# we're almost there, but the changes are in the index at the moment,
# hence one more step (exactly as git gently suggests):
# (use "git reset HEAD <file>..." to unstage)
git reset

After this you'll see this shiny Unstaged changes after reset: and your repo is in a state like you're about to commit all these files. From now on you can easily commit it again like you usually do. Hope it helps.

The correct approach is to use a single timer. Using setInterval, you can achieve what you want as follows:

window.onload = function start() {
    slide();
}
function slide() {
    var num = 0, style = document.getElementById('container').style;
    window.setInterval(function () {
        // increase by num 1, reset to 0 at 4
        num = (num + 1) % 4;

        // -600 * 1 = -600, -600 * 2 = -1200, etc 
        style.marginLeft = (-600 * num) + "px"; 
    }, 3000); // repeat forever, polling every 3 seconds
}

put .gitignore in your main catalog

git status (you will see which files you can commit)
git add -A
git commit -m "message"
git push

To define a global variable which is based off a DOM element a few things must be checked. First, if the code is in the <head> section, then the DOM will not loaded on execution. In this case, an event handler must be placed in order to set the variable after the DOM has been loaded, like this:

var systemStatus;
window.onload = function(){ systemStatus = document.getElementById("system_status"); };

However, if this script is inline in the page as the DOM loads, then it can be done as long as the DOM element in question has loaded above where the script is located. This is because javascript executes synchronously. This would be valid:

<div id="system_status"></div>
<script type="text/javascript">
 var systemStatus = document.getElementById("system_status");
</script>

As a result of the latter example, most pages which run scripts in the body save them until the very end of the document. This will allow the page to load, and then the javascript to execute which in most cases causes a visually faster rendering of the DOM.

With the release of Android Studio 4.1 Canary and Dev preview , you can use a new tool called

Database Inspector

Install AS 4.1+, run the app, open database inspector, now you can view your database files on the left side of the database inspector panel then select the table to view the content.

Live Queries

Either you can run you queries using Run SQL option or if you are using Room then open database inspector and run the app then, you can run the DAO queries in your interface by clicking on the run button on left of @Query annotation.

In package.json, add something like (This version is ok for Angular 2):

  "ngx-order-pipe": "^1.1.3",

In your typescript module (and imports array):

  import { OrderModule } from 'ngx-order-pipe';

You can only have one output path.

from the docs https://github.com/webpack/docs/wiki/configuration#output

Options affecting the output of the compilation. output options tell Webpack how to write the compiled files to disk. Note, that while there can be multiple entry points, only one output configuration is specified.

If you use any hashing ([hash] or [chunkhash]) make sure to have a consistent ordering of modules. Use the OccurenceOrderPlugin or recordsPath.

Yes, in your formula, you can cbind the numeric variables to be aggregated:

aggregate(cbind(x1, x2) ~ year + month, data = df1, sum, na.rm = TRUE)
   year month         x1          x2
1  2000     1   7.862002   -7.469298
2  2001     1 276.758209  474.384252
3  2000     2  13.122369 -128.122613
...
23 2000    12  63.436507  449.794454
24 2001    12 999.472226  922.726589

The below code working for me on array coming from ajax call .

  $form = $request->input('form');
  $rules = array(
            'facebook_account' => 'url',
            'youtube_account' => 'url',
            'twitter_account' => 'url',
            'instagram_account' => 'url',
            'snapchat_account' => 'url',
            'website' => 'url',
        );
        $validation = Validator::make($form, $rules);

        if ($validation->fails()) {
            return Response::make(['error' => $validation->errors()], 400);
        }

1. :datetime (8 bytes)

   • Stores Date and Time formatted YYYY-MM-DD HH:MM:SS
   • Useful for columns like birth_date

2. :timestamp (4 bytes)

   • Stores number of seconds since 1970-01-01
   • Useful for columns like updated_at, created_at
3. :date (3 bytes)
   • Stores Date
4. :time (3 bytes)
   • Stores Time

Best way would be to declare Boolean variable within the code block and return it at end of code, like this:

public boolean Test(){
    boolean booleanFlag= true; 
    if (A>B)
    {booleanFlag= true;}
    else 
    {booleanFlag = false;}
    return booleanFlag;

}

I find this the best way.

char ch='A';

System.out.println((int)ch);

You can group your specific layout under the correct folder structure as follows.

layout-land-target_version

ie

layout-land-19 // target KitKat

likewise you can create your layouts.

If you want to use Plugin then here is one

Time complexity is O(E+V) instead of O(2E+V) because if the time complexity is n^2+2n+7 then it is written as O(n^2).

Hence, O(2E+V) is written as O(E+V)

because difference between n^2 and n matters but not between n and 2n.

Assuming you're asking about the common "index hinting" feature found in many databases, PostgreSQL doesn't provide such a feature. This was a conscious decision made by the PostgreSQL team. A good overview of why and what you can do instead can be found here. The reasons are basically that it's a performance hack that tends to cause more problems later down the line as your data changes, whereas PostgreSQL's optimizer can re-evaluate the plan based on the statistics. In other words, what might be a good query plan today probably won't be a good query plan for all time, and index hints force a particular query plan for all time.

As a very blunt hammer, useful for testing, you can use the enable_seqscan and enable_indexscan parameters. See:

• Examining index usage
• enable_ parameters

These are not suitable for ongoing production use. If you have issues with query plan choice, you should see the documentation for tracking down query performance issues. Don't just set enable_ params and walk away.

Unless you have a very good reason for using the index, Postgres may be making the correct choice. Why?

• For small tables, it's faster to do sequential scans.
• Postgres doesn't use indexes when datatypes don't match properly, you may need to include appropriate casts.
• Your planner settings might be causing problems.

See also this old newsgroup post.

You can try this code:

USE AdventureWorks2012;
GO
SET STATISTICS TIME ON;
GO
SELECT ProductID, StartDate, EndDate, StandardCost 
FROM Production.ProductCostHistory
WHERE StandardCost < 500.00;
GO
SET STATISTICS TIME OFF;
GO

In the "Developer Tab" go to "Visual Basic" and create a Module. Copy paste the following. Remember changing the code, depending on what you want. Then run the module.

  Sub sbDelete_Rows_IF_Cell_Contains_String_Text_Value()
    Dim lRow As Long
    Dim iCntr As Long
    lRow = 390
    For iCntr = lRow To 1 Step -1
        If Cells(iCntr, 5).Value = "none" Then
            Rows(iCntr).Delete
        End If
    Next
    End Sub

lRow : Put the number of the rows that the current file has.

The number "5" in the "If" is for the fifth (E) column

1. The meaning of shapes in NumPy

You write, "I know literally it's list of numbers and list of lists where all list contains only a number" but that's a bit of an unhelpful way to think about it.

The best way to think about NumPy arrays is that they consist of two parts, a data buffer which is just a block of raw elements, and a view which describes how to interpret the data buffer.

For example, if we create an array of 12 integers:

>>> a = numpy.arange(12)
>>> a
array([ 0,  1,  2,  3,  4,  5,  6,  7,  8,  9, 10, 11])

Then a consists of a data buffer, arranged something like this:

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

and a view which describes how to interpret the data:

>>> a.flags
  C_CONTIGUOUS : True
  F_CONTIGUOUS : True
  OWNDATA : True
  WRITEABLE : True
  ALIGNED : True
  UPDATEIFCOPY : False
>>> a.dtype
dtype('int64')
>>> a.itemsize
8
>>> a.strides
(8,)
>>> a.shape
(12,)

Here the shape (12,) means the array is indexed by a single index which runs from 0 to 11. Conceptually, if we label this single index i, the array a looks like this:

i= 0    1    2    3    4    5    6    7    8    9   10   11
+-----------------------------------------------------------+
¦  0 ¦  1 ¦  2 ¦  3 ¦  4 ¦  5 ¦  6 ¦  7 ¦  8 ¦  9 ¦ 10 ¦ 11 ¦
+-----------------------------------------------------------+

If we reshape an array, this doesn't change the data buffer. Instead, it creates a new view that describes a different way to interpret the data. So after:

>>> b = a.reshape((3, 4))

the array b has the same data buffer as a, but now it is indexed by two indices which run from 0 to 2 and 0 to 3 respectively. If we label the two indices i and j, the array b looks like this:

i= 0    0    0    0    1    1    1    1    2    2    2    2
j= 0    1    2    3    0    1    2    3    0    1    2    3
+-----------------------------------------------------------+
¦  0 ¦  1 ¦  2 ¦  3 ¦  4 ¦  5 ¦  6 ¦  7 ¦  8 ¦  9 ¦ 10 ¦ 11 ¦
+-----------------------------------------------------------+

which means that:

>>> b[2,1]
9

You can see that the second index changes quickly and the first index changes slowly. If you prefer this to be the other way round, you can specify the order parameter:

>>> c = a.reshape((3, 4), order='F')

which results in an array indexed like this:

i= 0    1    2    0    1    2    0    1    2    0    1    2
j= 0    0    0    1    1    1    2    2    2    3    3    3
+-----------------------------------------------------------+
¦  0 ¦  1 ¦  2 ¦  3 ¦  4 ¦  5 ¦  6 ¦  7 ¦  8 ¦  9 ¦ 10 ¦ 11 ¦
+-----------------------------------------------------------+

which means that:

>>> c[2,1]
5

It should now be clear what it means for an array to have a shape with one or more dimensions of size 1. After:

>>> d = a.reshape((12, 1))

the array d is indexed by two indices, the first of which runs from 0 to 11, and the second index is always 0:

i= 0    1    2    3    4    5    6    7    8    9   10   11
j= 0    0    0    0    0    0    0    0    0    0    0    0
+-----------------------------------------------------------+
¦  0 ¦  1 ¦  2 ¦  3 ¦  4 ¦  5 ¦  6 ¦  7 ¦  8 ¦  9 ¦ 10 ¦ 11 ¦
+-----------------------------------------------------------+

and so:

>>> d[10,0]
10

A dimension of length 1 is "free" (in some sense), so there's nothing stopping you from going to town:

>>> e = a.reshape((1, 2, 1, 6, 1))

giving an array indexed like this:

i= 0    0    0    0    0    0    0    0    0    0    0    0
j= 0    0    0    0    0    0    1    1    1    1    1    1
k= 0    0    0    0    0    0    0    0    0    0    0    0
l= 0    1    2    3    4    5    0    1    2    3    4    5
m= 0    0    0    0    0    0    0    0    0    0    0    0
+-----------------------------------------------------------+
¦  0 ¦  1 ¦  2 ¦  3 ¦  4 ¦  5 ¦  6 ¦  7 ¦  8 ¦  9 ¦ 10 ¦ 11 ¦
+-----------------------------------------------------------+

and so:

>>> e[0,1,0,0,0]
6

See the NumPy internals documentation for more details about how arrays are implemented.

2. What to do?

Since numpy.reshape just creates a new view, you shouldn't be scared about using it whenever necessary. It's the right tool to use when you want to index an array in a different way.

However, in a long computation it's usually possible to arrange to construct arrays with the "right" shape in the first place, and so minimize the number of reshapes and transposes. But without seeing the actual context that led to the need for a reshape, it's hard to say what should be changed.

The example in your question is:

numpy.dot(M[:,0], numpy.ones((1, R)))

but this is not realistic. First, this expression:

M[:,0].sum()

computes the result more simply. Second, is there really something special about column 0? Perhaps what you actually need is:

M.sum(axis=0)

You can try this

SET GLOBAL group_concat_max_len = 1000000;

query runs a standard SQL statement and requires you to properly escape all data to avoid SQL Injections and other issues.

execute runs a prepared statement which allows you to bind parameters to avoid the need to escape or quote the parameters. execute will also perform better if you are repeating a query multiple times. Example of prepared statements:

$sth = $dbh->prepare('SELECT name, colour, calories FROM fruit
    WHERE calories < :calories AND colour = :colour');
$sth->bindParam(':calories', $calories);
$sth->bindParam(':colour', $colour);
$sth->execute();
// $calories or $color do not need to be escaped or quoted since the
//    data is separated from the query

Best practice is to stick with prepared statements and execute for increased security.

See also: Are PDO prepared statements sufficient to prevent SQL injection?

It is an extremely overused way to check for the success/failure of a command. Typically, the code snippet you give would be refactored as:

if grep -e ERROR ${LOG_DIR_PATH}/${LOG_NAME} > /dev/null; then
   ...
fi

(Although you can use 'grep -q' in some instances instead of redirecting to /dev/null, doing so is not portable. Many implementations of grep do not support the -q option, so your script may fail if you use it.)

I've always used it on the command line and not as a library, but HTMLDOC gives me excellent results, and it handles at least some CSS (I couldn't easily see how much).

Here's a sample command line

htmldoc --webpage -t pdf --size letter --fontsize 10pt index.html > index.pdf

"javascript.implicitProjectConfig.experimentalDecorators": true

Will solve this problem.

Using the same process for the service and the activity and START_STICKY or START_REDELIVER_INTENT in the service is the only way to be able to restart the service when the application restarts, which happens when the user closes the application for example, but also when the system decides to close it for optimisations reasons. You CAN NOT have a service that will run permanently without any interruption. This is by design, smartphones are not made to run continuous processes for long period of time. This is due to the fact that battery life is the highest priority. You need to design your service so it handles being stopped at any point.

It can be something so silly as you are transferring the file via FTP to a target machine, you go and run the .JAR file but this was so big that it has not yet been finished transferred :) Yes it happened to me..

$("#HowYouKnow option:eq(XXX)").attr('selected', 'selected');

where XXX is the index of the one you want.

Short answer: No, the statement in the currently accepted answer is NOT accurate: "The general consensus is that you do not (should not) need to dispose of HttpClient".

Long answer: BOTH of the following statements are true and achieveable at the same time:

1. "HttpClient is intended to be instantiated once and re-used throughout the life of an application", quoted from official documentation.
2. An IDisposable object is supposed/recommended to be disposed.

And they DO NOT NECESSARILY CONFLICT with each other. It is just a matter of how you organize your code to reuse an HttpClient AND still dispose it properly.

An even longer answer quoted from my another answer:

It is not a coincidence to see people in some blog posts blaming how HttpClient 's IDisposable interface makes them tend to use the using (var client = new HttpClient()) {...} pattern and then lead to exhausted socket handler problem.

I believe that comes down to an unspoken (mis?)conception: "an IDisposable object is expected to be short-lived".

HOWEVER, while it certainly looks like a short-lived thing when we write code in this style:

using (var foo = new SomeDisposableObject())
{
    ...
}

the official documentation on IDisposable never mentions IDisposable objects have to be short-lived. By definition, IDisposable is merely a mechanism to allow you to release unmanaged resources. Nothing more. In that sense, you are EXPECTED to eventually trigger the disposal, but it does not require you to do so in a short-lived fashion.

It is therefore your job to properly choose when to trigger the disposal, base on your real object's life cycle requirement. There is nothing stopping you from using an IDisposable in a long-lived way:

using System;
namespace HelloWorld
{
    class Hello
    {
        static void Main()
        {
            Console.WriteLine("Hello World!");

            using (var client = new HttpClient())
            {
                for (...) { ... }  // A really long loop

                // Or you may even somehow start a daemon here

            }

            // Keep the console window open in debug mode.
            Console.WriteLine("Press any key to exit.");
            Console.ReadKey();
        }
    }
}

With this new understanding, now we revisit that blog post, we can clearly notice that the "fix" initializes HttpClient once but never dispose it, that is why we can see from its netstat output that, the connection remains at ESTABLISHED state which means it has NOT been properly closed. If it were closed, its state would be in TIME_WAIT instead. In practice, it is not a big deal to leak only one connection open after your entire program ends, and the blog poster still see a performance gain after the fix; but still, it is conceptually incorrect to blame IDisposable and choose to NOT dispose it.

• Pro base64: the encoded representation you handle is a pretty safe string. It contains neither control chars nor quotes. The latter point helps against SQL injection attempts. I wouldn't expect any problem to just add the value to a "hand coded" SQL query string.

• Pro BLOB: the database manager software knows what type of data it has to expect. It can optimize for that. If you'd store base64 in a TEXT field it might try to build some index or other data structure for it, which would be really nice and useful for "real" text data but pointless and a waste of time and space for image data. And it is the smaller, as in number of bytes, representation.

For me the padding solution wasn't good, as I was using border on the button, and would've been hard to put modify the markup to create an overlay for the touch area.

So what I did, is I just used the :before pseudo tag, and created an overlay, which was perfect in my case, as the click event propagated the same way.

button.my-button:before {
    content: '';
    position: absolute;
    width: 26px;
    height: 26px;

?+?+?/?/?/? will let you navigate split panes in the direction of the arrow, i.e. when using ?+D to split panes vertically, ?+?+? and ?+?+? will let you switch between the panes.

When you are checking if an element has or does not have a class, make sure you didn't accidentally put a dot in the class name:

<div class="className"></div>

$('div').hasClass('className');
$('div').hasClass('.className'); #will not work!!!!

After a long time of staring at my code I realized I had done this. A little typo like this took me an hour to figure out what I had done wrong. Check your code!

In Visual Studio Code you can:

• Go to the Explorer
• Right click the first file you want to compare
• Select Select for compare
• Right click on the second file you want to compare
• Select Compare with '[NAME OF THE PREVIOUSLY SELECTED FILE]'

To add to what other suggested I like the following construct to avoid the annoyance of adding members to keyvaluepair collections.

public class KeyValuePairList<Tkey,TValue> : List<KeyValuePair<Tkey,TValue>>{
    public void Add(Tkey key, TValue value){
        base.Add(new KeyValuePair<Tkey, TValue>(key, value));
    }
}

What this means is that the constructor can be initialized with better syntax::

var myList = new KeyValuePairList<int,string>{{1,"one"},{2,"two"},{3,"three"}};

I personally like the above code over the more verbose examples Unfortunately C# does not really support tuple types natively so this little hack works wonders.

If you find yourself really needing more than 2, I suggest creating abstractions against the tuple type.(although Tuple is a class not a struct like KeyValuePair this is an interesting distinction).

Curiously enough, the initializer list syntax is available on any IEnumerable and it allows you to use any Add method, even those not actually enumerable by your object. It's pretty handy to allow things like adding an object[] member as a params object[] member.

It's just what it says:

inputFile = open((x), encoding = "utf8", "r")

You have specified encoding as a keyword argument, but "r" as a positional argument. You can't have positional arguments after keyword arguments. Perhaps you wanted to do:

inputFile = open((x), "r", encoding = "utf8")

My Solution is to define an RStudio snippet as follows:

snippet pp
    "`r gsub("\\\\", "\\\\\\\\\\\\\\\\", readClipboard())`"

This snippet converts backslashes \ into double backslashes \\. The following version will work if you prefer to convert backslahes to forward slashes /.

snippet pp
    "`r gsub("\\\\", "/", readClipboard())`"

Once your preferred snippet is defined, paste a path from the clipboard by typing p-p-TAB-ENTER (that is pp and then the tab key and then enter) and the path will be magically inserted with R friendly delimiters.

I don't exactly understand what's the problem. Incomplete type is not the type that's "missing". Incompete type is a type that is declared but not defined (in case of struct types). To find the non-defining declaration is easy. As for the finding the missing definition... the compiler won't help you here, since that is what caused the error in the first place.

A major reason for incomplete type errors in C are typos in type names, which prevent the compiler from matching one name to the other (like in matching the declaration to the definition). But again, the compiler cannot help you here. Compiler don't make guesses about typos.

Your data types are mismatched when you are retrieving the field values.

Also check how you store your enums, default is ORDINAL (numeric value stored in database), but STRING (name of enum stored in database) is also an option. Make sure the Entity in your code and the Model in your database are exactly the same.

I had an enum mismatch. It was set to default (ORDINAL) but the database model was expecting a string VARCHAR2(100char). Solution: @Enumerated(EnumType.STRING)

Consider using String#format with proper format specifications (%d or %f) instead.

int value = 10;

textView.setText(String.format("%d",value));

This will handle fraction separator and locale specific digits properly

as a sidenote, replace doesn't have to move all zeros. If you just want to remove the first specify count to 1:

'asd0asd0'.replace('0','',1)

Out:

'asdasd0'

Use this to implement mask:

https://rawgit.com/RobinHerbots/jquery.inputmask/3.x/dist/jquery.inputmask.bundle.js

<input id="phn-number" class="ant-input" type="text" placeholder="(XXX) XXX-XXXX" data-inputmask-mask="(999) 999-9999">


jQuery( '#phn-number[data-inputmask-mask]' ).inputmask();

Lots of suggestions using Regex. How about this extension method without it:

public static string Replace(this string str, string old, string @new, StringComparison comparison)
{
    @new = @new ?? "";
    if (string.IsNullOrEmpty(str) || string.IsNullOrEmpty(old) || old.Equals(@new, comparison))
        return str;
    int foundAt = 0;
    while ((foundAt = str.IndexOf(old, foundAt, comparison)) != -1)
    {
        str = str.Remove(foundAt, old.Length).Insert(foundAt, @new);
        foundAt += @new.Length;
    }
    return str;
}

There is no semicolon at the end of that instruction causing the error.

EDIT

Like RiverC pointed out, there is no semicolon at the end of the previous line!

require ("scripts/connect.php") 

EDIT

It seems you have no-semicolons whatsoever.

http://php.net/manual/en/language.basic-syntax.instruction-separation.php

As in C or Perl, PHP requires instructions to be terminated with a semicolon at the end of each statement.

You can use a list comprehension to filter it:

j2 = [i for i in j if i >= 5]

If you actually want it sorted like your example was, you can use sorted:

j2 = sorted(i for i in j if i >= 5)

or call sort on the final list:

j2 = [i for i in j if i >= 5]
j2.sort()

I think this is the less code it's possible, it uses Guava Joiner class:

Joiner.on("").join(Collections.nCopies(10, " "));

I had this issue; I fixed it by going to

Computer-->Properties-->Advanced Settings-->Environmental Variables

In the System Variables find the variable named PATH.
-->Select Edit -->At the very end of the Path Variable, put a ";" then add your path of your JDK and put \bin\ at the end

Should be fixed.

Example:

System Variable-

C:\Program Files (x86)\Common Files.......HP\LeanFT\bin

JDK path-

C:\Programs Files\Java\jre1.8.0_121

Final Path -

C:\Program Files (x86)\Common Files.......HP\LeanFT\bin;C:\Programs Files\Java\jre1.8.0_121\bin\

This is my take on the various answers. I wanted to actually see the logged messages, even if I did not have the IE console open when they were fired, so I push them into a console.messages array that I create. I also added a function console.dump() to facilitate viewing the whole log. console.clear() will empty the message queue.

This solutions also "handles" the other Console methods (which I believe all originate from the Firebug Console API)

Finally, this solution is in the form of an IIFE, so it does not pollute the global scope. The fallback function argument is defined at the bottom of the code.

I just drop it in my master JS file which is included on every page, and forget about it.

(function (fallback) {    

    fallback = fallback || function () { };

    // function to trap most of the console functions from the FireBug Console API. 
    var trap = function () {
        // create an Array from the arguments Object           
        var args = Array.prototype.slice.call(arguments);
        // console.raw captures the raw args, without converting toString
        console.raw.push(args);
        var message = args.join(' ');
        console.messages.push(message);
        fallback(message);
    };

    // redefine console
    if (typeof console === 'undefined') {
        console = {
            messages: [],
            raw: [],
            dump: function() { return console.messages.join('\n'); },
            log: trap,
            debug: trap,
            info: trap,
            warn: trap,
            error: trap,
            assert: trap,
            clear: function() { 
                  console.messages.length = 0; 
                  console.raw.length = 0 ;
            },
            dir: trap,
            dirxml: trap,
            trace: trap,
            group: trap,
            groupCollapsed: trap,
            groupEnd: trap,
            time: trap,
            timeEnd: trap,
            timeStamp: trap,
            profile: trap,
            profileEnd: trap,
            count: trap,
            exception: trap,
            table: trap
        };
    }

})(null); // to define a fallback function, replace null with the name of the function (ex: alert)

Some extra info

The line var args = Array.prototype.slice.call(arguments); creates an Array from the arguments Object. This is required because arguments is not really an Array.

trap() is a default handler for any of the API functions. I pass the arguments to message so that you get a log of the arguments that were passed to any API call (not just console.log).

Edit

I added an extra array console.raw that captures the arguments exactly as passed to trap(). I realized that args.join(' ') was converting objects to the string "[object Object]" which may sometimes be undesirable. Thanks bfontaine for the suggestion.

In App.js

 import {useHistory } from "react-router-dom";

 const TheContext = React.createContext(null);

 const App = () => {
   const history = useHistory();

   <TheContext.Provider value={{ history, user }}>

    <Switch>
        <Route exact path="/" render={(props) => <Home {...props} />} />
        <Route
          exact
          path="/sign-up"
          render={(props) => <SignUp {...props} setUser={setUser} />}
        /> ...

Then in a child component :

const Welcome = () => {
    
    const {user, history} = React.useContext(TheContext); 
    ....

$(document).ready(function () {
    $('input:radio[name=bedStatus]:checked').change(function () {
        if ($("input:radio[name='bedStatus']:checked").val() == 'allot') {
            alert("Allot Thai Gayo Bhai");
        }
        if ($("input:radio[name='bedStatus']:checked").val() == 'transfer') {
            alert("Transfer Thai Gayo");
        }
    });
});

var inValid = new RegExp('^[_A-z0-9]{1,}$');
var value = "test string";
var k = inValid.test(value);
alert(k);

This works,

#!/usr/bin/Rscript

but I don't know what happens if you have more than 1 version of R installed on your machine.

If you do it like this

#!/usr/bin/env Rscript

it tells the interpreter to just use whatever R appears first on your path.

tar -zcvf compressFileName.tar.gz folderToCompress

everything in folderToCompress will go to compressFileName

Edit: After review and comments I realized that people may get confused with compressFileName without an extension. If you want you can use .tar.gz extension(as suggested) with the compressFileName

Just in case there is someone out there who's a bit new like me, double check that you are spelling your header folders correctly.

For example:

<#include "Component/BoxComponent.h"

This will result in the error. Instead, it needs to be:

<#include "Components/BoxComponent.h"

I'm running Windows 10 Professional with Visual Studio 2017 and none of the options above worked for me.

What fixed it for me was adding 'Windows Process Activation Service'.

Start > Type turn windows Features On or Off > Make sure "Windows Process Activation Service" is checked.

Hope it helps someone.

Example for a public system resource:

// this will get id for android.R.drawable.ic_dialog_alert
int id = Resources.getSystem().getIdentifier("ic_dialog_alert", "drawable", "android");

Another way is to refer the documentation for android.R.drawable class.

This is using the :hover pseudoelement in CSS3.

HTML:

<div id="wrapper">
    <img src="http://placehold.it/300x200" class="hover" />
    <p class="text">text</p>
</div>?

CSS:

#wrapper .text {
position:relative;
bottom:30px;
left:0px;
visibility:hidden;
}

#wrapper:hover .text {
visibility:visible;
}

?Demo HERE.

This instead is a way of achieving the same result by using jquery:

HTML:

<div id="wrapper">
    <img src="http://placehold.it/300x200" class="hover" />
    <p class="text">text</p>
</div>?

CSS:

#wrapper p {
position:relative;
bottom:30px;
left:0px;
visibility:hidden;
}

jquery code:

$('.hover').mouseover(function() {
  $('.text').css("visibility","visible");
});

$('.hover').mouseout(function() {
  $('.text').css("visibility","hidden");
});

You can put the jquery code where you want, in the body of the HTML page, then you need to include the jquery library in the head like this:

<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
</head>

You can see the demo HERE.

When you want to use it on your website, just change the <img src /> value and you can add multiple images and captions, just copy the format i used: insert image with class="hover" and p with class="text"

Number.prototype.toFixed is a function designed to format a number before printing it out. It's from the family of toString, toExponential and toPrecision.

To round a number, you would do this:

someNumber = 42.008;
someNumber = Math.round( someNumber * 1e2 ) / 1e2;
someNumber === 42.01;

// if you need 3 digits, replace 1e2 with 1e3 etc.
// or just copypaste this function to your code:

function toFixedNumber(num, digits, base){
  var pow = Math.pow(base||10, digits);
  return Math.round(num*pow) / pow;
}

.

Or if you want a “native-like” function, you can extend the prototype:

Number.prototype.toFixedNumber = function(digits, base){
  var pow = Math.pow(base||10, digits);
  return Math.round(this*pow) / pow;
}

someNumber = 42.008;
someNumber = someNumber.toFixedNumber(2);
someNumber === 42.01;


//or even hexadecimal

someNumber = 0xAF309/256  //which is af3.09
someNumber = someNumber.toFixedNumber(1, 16);
someNumber.toString(16) === "af3.1";

However, bear in mind that polluting the prototype is considered bad when you're writing a module, as modules shouldn't have any side effects. So, for a module, use the first function.

Joininig @Rudi's and @Pete's answers. I have created an RotateAnimation that keeps buttons functionality also after rotation.

setRotation() method preserves buttons functionality.

Code Sample:

Animation an = new RotateAnimation(0.0f, 180.0f, mainLayout.getWidth()/2, mainLayout.getHeight()/2);

    an.setDuration(1000);              
    an.setRepeatCount(0);                     
    an.setFillAfter(false);              // DO NOT keep rotation after animation
    an.setFillEnabled(true);             // Make smooth ending of Animation
    an.setAnimationListener(new AnimationListener() {
        @Override
        public void onAnimationStart(Animation animation) {}

        @Override
        public void onAnimationRepeat(Animation animation) {}

        @Override
        public void onAnimationEnd(Animation animation) {
                mainLayout.setRotation(180.0f);      // Make instant rotation when Animation is finished
            }
            }); 

mainLayout.startAnimation(an);

mainLayout is a (LinearLayout) field

As mentioned by Chris Fritz (Vue.js Core Team Emeriti) in VueCONF US 2019

if we had Kia enter .native and then the root element of the base input changed from an input to a label suddenly this component is broken and it's not obvious and in fact, you might not even catch it right away unless you have a really good test. Instead by avoiding the use of the .native modifier which I currently consider an anti-pattern will be removed in Vue 3 you'll be able to explicitly define that the parent might care about which element listeners are added to...

With Vue 2

Using $listeners:

So, if you are using Vue 2 a better option to resolve this issue would be to use a fully transparent wrapper logic. For this Vue provides a $listeners property containing an object of listeners being used on the component. For example:

{
  focus: function (event) { /* ... */ }
  input: function (value) { /* ... */ },
}

and then we just need to add v-on="$listeners" to the test component like:

Test.vue (child component)

<template>
  <div v-on="$listeners">
    click here
  </div>
</template>

Now the <test> component is a fully transparent wrapper, meaning it can be used exactly like a normal <div> element: all the listeners will work, without the .native modifier.

Demo:

Vue.component('test', {_x000D_
  template: `_x000D_
    <div class="child" v-on="$listeners">_x000D_
      Click here_x000D_
    </div>`_x000D_
})_x000D_
_x000D_
new Vue({_x000D_
  el: "#myApp",_x000D_
  data: {},_x000D_
  methods: {_x000D_
    testFunction: function(event) {_x000D_
      console.log('test clicked')_x000D_
    }_x000D_
  }_x000D_
})

div.child{border:5px dotted orange; padding:20px;}

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.min.js"></script>_x000D_
<div id="myApp">_x000D_
  <test @click="testFunction"></test>_x000D_
</div>

Using $emit method:

We can also use $emit method for this purpose, which helps us to listen to child components events in parent component. For this, we first need to emit a custom event from child component like:

Test.vue (child component)

<test @click="$emit('my-event')"></test>

Important: Always use kebab-case for event names. For more information and demo regading this point please check out this answer: VueJS passing computed value from component to parent.

Now, we just need to listen to this emitted custom event in parent component like:

App.vue

<test @my-event="testFunction"></test>

So, basically instead of v-on:click or the shorthand @click we will simply use v-on:my-event or just @my-event.

Demo:

Vue.component('test', {_x000D_
  template: `_x000D_
    <div class="child" @click="$emit('my-event')">_x000D_
      Click here_x000D_
    </div>`_x000D_
})_x000D_
_x000D_
new Vue({_x000D_
  el: "#myApp",_x000D_
  data: {},_x000D_
  methods: {_x000D_
    testFunction: function(event) {_x000D_
      console.log('test clicked')_x000D_
    }_x000D_
  }_x000D_
})

div.child{border:5px dotted orange; padding:20px;}

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.min.js"></script>_x000D_
<div id="myApp">_x000D_
  <test @my-event="testFunction"></test>_x000D_
</div>

With Vue 3

Using v-bind="$attrs":

Vue 3 is going to make our life much easier in many ways. One of the examples for it is that it will help us to create a simpler transparent wrapper with very less config by just using v-bind="$attrs". By using this on child components not only our listener will work directly from the parent but also any other attribute will also work just like it a normal <div> only.

So, with respect to this question, we will not need to update anything in Vue 3 and your code will still work fine as <div> is the root element here and it will automatically listen to all child events.

Demo #1:

const { createApp } = Vue;_x000D_
_x000D_
const Test = {_x000D_
  template: `_x000D_
    <div class="child">_x000D_
      Click here_x000D_
    </div>`_x000D_
};_x000D_
_x000D_
const App = {_x000D_
  components: { Test },_x000D_
  setup() {_x000D_
    const testFunction = event => {_x000D_
      console.log("test clicked");_x000D_
    };_x000D_
    return { testFunction };_x000D_
  }_x000D_
};_x000D_
_x000D_
createApp(App).mount("#myApp");

div.child{border:5px dotted orange; padding:20px;}

<script src="//unpkg.com/vue@next"></script>_x000D_
<div id="myApp">_x000D_
  <test v-on:click="testFunction"></test>_x000D_
</div>

But for complex components with nested elements where we need to apply attributes and events to main <input /> instead of the parent label we can simply use v-bind="$attrs"

Demo #2:

const { createApp } = Vue;_x000D_
_x000D_
const BaseInput = {_x000D_
  props: ['label', 'value'],_x000D_
  template: `_x000D_
    <label>_x000D_
      {{ label }}_x000D_
      <input v-bind="$attrs">_x000D_
    </label>`_x000D_
};_x000D_
_x000D_
const App = {_x000D_
  components: { BaseInput },_x000D_
  setup() {_x000D_
    const search = event => {_x000D_
      console.clear();_x000D_
      console.log("Searching...", event.target.value);_x000D_
    };_x000D_
    return { search };_x000D_
  }_x000D_
};_x000D_
_x000D_
createApp(App).mount("#myApp");

input{padding:8px;}

<script src="//unpkg.com/vue@next"></script>_x000D_
<div id="myApp">_x000D_
  <base-input _x000D_
    label="Search: "_x000D_
    placeholder="Search"_x000D_
    @keyup="search">_x000D_
  </base-input><br/>_x000D_
</div>

I faced similar problem today. So, here's a simple solution: While doing SSH to the machine, just add Ctrl - Y.

ssh user@ip_address -Y

After login, type firefox &. And you are good to go.

You need reinstall VS.

Language Pack Support in Visual Studio 2017 RC

Issue:

This release of Visual Studio supports only a single language pack for the user interface. You cannot install two languages for the user interface in the same instance of Visual Studio. In addition, you must select the language of Visual Studio during the initial install, and cannot change it during Modify.

Workaround:

These are known issues that will be fixed in an upcoming release. To change the language in this release, you can uninstall and reinstall Visual Studio.

Reference: https://www.visualstudio.com/en-us/news/releasenotes/vs2017-relnotes#november-16-2016

You can update values from another table using inner join like this

UPDATE [table1_name] AS t1 INNER JOIN [table2_name] AS t2 ON t1.column1_name] = t2.[column1_name] SET t1.[column2_name] = t2.column2_name];

Follow here to know how to use this query http://www.voidtricks.com/mysql-inner-join-update/

or you can use select as subquery to do this

UPDATE [table_name] SET [column_name] = (SELECT [column_name] FROM [table_name] WHERE [column_name] = [value]) WHERE [column_name] = [value];

query explained in details here http://www.voidtricks.com/mysql-update-from-select/

A very simple solution considering you have object A and B:

foreach($objB AS $var=>$value){
    $objA->$var = $value;
}

That's all. You now have objA with all values from objB.

str = str.replaceAll("\\D+","");

See this fiddle (actually updated your's)

You need to hook into componentDidMount which is run after render method. There, you get actual height of element.

var DivSize = React.createClass({
    getInitialState() {
    return { state: 0 };
  },

  componentDidMount() {
    const height = document.getElementById('container').clientHeight;
    this.setState({ height });
  },

  render: function() {
    return (
        <div className="test">
        Size: <b>{this.state.height}px</b> but it should be 18px after the render
      </div>
    );
  }
});

ReactDOM.render(
  <DivSize />,
  document.getElementById('container')
);

<script src="https://facebook.github.io/react/js/jsfiddle-integration-babel.js"></script>

<div id="container">
<p>
jnknwqkjnkj<br>
jhiwhiw (this is 36px height)
</p>
    <!-- This element's contents will be replaced with your component. -->
</div>

Not for nothing, but you shouldn't just automatically use the latest library. If they release the newest library tomorrow and it breaks some of your scripts, you are SOL, but if you use the library you used to develop the scripts, you will ensure they will work.

just run git log origin/$BRANCH_NAME

I don't know what qualifies as best but zxing has a qr code generator for java, is actively developed, and is liberally licensed.

If you have an abstract URL string (not from the current window.location), you can use this trick:

let yourUrlString = "http://example.com:3000/pathname/?search=test#hash";

let parser = document.createElement('a');
parser.href = yourUrlString;

parser.protocol; // => "http:"
parser.hostname; // => "example.com"
parser.port;     // => "3000"
parser.pathname; // => "/pathname/"
parser.search;   // => "?search=test"
parser.hash;     // => "#hash"
parser.host;     // => "example.com:3000"

What worked for me:

• Open my.ini with Notepad++
• Encoding --> convert to ANSI
• save

BTW you can pass the error message directly to sys.exit:

if len(sys.argv) < 2:
    sys.exit('Usage: %s database-name' % sys.argv[0])

if not os.path.exists(sys.argv[1]):
    sys.exit('ERROR: Database %s was not found!' % sys.argv[1])

If you just want to see your DB & Tables then the esiest way is to use Stetho. Pretty cool tool for every Android developer who uses SQLite buit by Facobook developed.

Steps to use the tool

1. Add below dependeccy in your application`s gradle file (Module: app)

'compile 'com.facebook.stetho:stetho:1.4.2'

2. Add below lines of code in your Activity onCreate() method

@Override
 protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 Stetho.initializeWithDefaults(this);
 setContentView(R.layout.activity_main);
 }

Now, build your application & When the app is running, you can browse your app database, by opening chrome in the url:

chrome://inspect/#devices

Screenshots of the same are as below_

ChromeInspact

Your DB

Hope this will help to all! :)

Inline SVG coming from 3rd party sources (like Google charts) may not contain XML namespace attribute (xmlns="http://www.w3.org/2000/svg") in SVG element (or maybe it's removed once SVG is rendered - neither browser inspector nor jQuery commands from browser console show the namespace in SVG element).

When you need to re-purpose these svg snippets for your other needs (background-image in CSS or img element in HTML) watch out for the missing namespace. Without the namespace browsers may refuse to display SVG (regardless of the encoding utf8 or base64).

If you are using Oracle 10g, you can use the DECODE function to pivot the rows into columns:

CREATE TABLE doc_tab (
  loan_number VARCHAR2(20),
  document_type VARCHAR2(20),
  document_id VARCHAR2(20)
);

INSERT INTO doc_tab VALUES('992452533663', 'Voters ID', 'XPD0355636');
INSERT INTO doc_tab VALUES('992452533663', 'Pan card', 'CHXPS5522D');
INSERT INTO doc_tab VALUES('992452533663', 'Drivers licence', 'DL-0420110141769');

COMMIT;

SELECT
    loan_number,
    MAX(DECODE(document_type, 'Voters ID', document_id)) AS voters_id,
    MAX(DECODE(document_type, 'Pan card', document_id)) AS pan_card,
    MAX(DECODE(document_type, 'Drivers licence', document_id)) AS drivers_licence
  FROM
    doc_tab
GROUP BY loan_number
ORDER BY loan_number;

Output:

LOAN_NUMBER   VOTERS_ID            PAN_CARD             DRIVERS_LICENCE    
------------- -------------------- -------------------- --------------------
992452533663  XPD0355636           CHXPS5522D           DL-0420110141769     

You can achieve the same using Oracle PIVOT clause, introduced in 11g:

SELECT *
  FROM doc_tab
PIVOT (
  MAX(document_id) FOR document_type IN ('Voters ID','Pan card','Drivers licence')
);
