To actually explain what happens:

The ADB executable has two components

• the server, which communicates with the device
• and the client, the command line, which communicates with the server.

When you start ADB for the first time you may notice a message like "starting ADB server". If you updated ADB after that, the newer executable needs to kill the obsolete server and start a new one with matching version.

This can also happen when you have multiple versions of ADB present on your development machine (Genymotion, Android SDK, phone OEM companion apps, various standalone scripts).

This does not concern the ADB installed on your phone/emulator.

The obvious (not necessarily easy) solution is to make sure you use the same version of ADB everywhere.

"I want a Bitmap d, that is grayscale. I do see a consructor that includes System.Drawing.Imaging.PixelFormat, but I don't understand how to use that."

Here is how to do this

Bitmap grayScaleBP = new 
         System.Drawing.Bitmap(2, 2, System.Drawing.Imaging.PixelFormat.Format16bppGrayScale);

EDIT: To convert to grayscale

             Bitmap c = new Bitmap("fromFile");
             Bitmap d;
             int x, y;

             // Loop through the images pixels to reset color.
             for (x = 0; x < c.Width; x++)
             {
                 for (y = 0; y < c.Height; y++)
                 {
                     Color pixelColor = c.GetPixel(x, y);
                     Color newColor = Color.FromArgb(pixelColor.R, 0, 0);
                     c.SetPixel(x, y, newColor); // Now greyscale
                 }
             }
            d = c;   // d is grayscale version of c  

Faster Version from switchonthecode follow link for full analysis:

public static Bitmap MakeGrayscale3(Bitmap original)
{
   //create a blank bitmap the same size as original
   Bitmap newBitmap = new Bitmap(original.Width, original.Height);

   //get a graphics object from the new image
   using(Graphics g = Graphics.FromImage(newBitmap)){

       //create the grayscale ColorMatrix
       ColorMatrix colorMatrix = new ColorMatrix(
          new float[][] 
          {
             new float[] {.3f, .3f, .3f, 0, 0},
             new float[] {.59f, .59f, .59f, 0, 0},
             new float[] {.11f, .11f, .11f, 0, 0},
             new float[] {0, 0, 0, 1, 0},
             new float[] {0, 0, 0, 0, 1}
          });

       //create some image attributes
       using(ImageAttributes attributes = new ImageAttributes()){

           //set the color matrix attribute
           attributes.SetColorMatrix(colorMatrix);

           //draw the original image on the new image
           //using the grayscale color matrix
           g.DrawImage(original, new Rectangle(0, 0, original.Width, original.Height),
                       0, 0, original.Width, original.Height, GraphicsUnit.Pixel, attributes);
       }
   }
   return newBitmap;
}

If you have access to the server then you can use

select local_tcp_port from sys.dm_exec_connections where local_tcp_port is not null

.NET Core is a free and open-source, managed computer software framework for Windows, Linux, and macOS operating systems. It is an open source, cross platform successor to .NET Framework.

.NET Core applications are supported on Windows, Linux, and macOS. In a nutshell .NET Core is similar to .NET framework, but it is cross-platform, i.e., it allows the .NET applications to run on Windows, Linux and MacOS. .NET framework applications can only run on the Windows system. So the basic difference between .NET framework and .NET core is that .NET Core is cross platform and .NET framework only runs on Windows.

Furthermore, .NET Core has built-in dependency injection by Microsoft and you do not have to use third-party software/DLL files for dependency injection.

You have to decompose the full object to reach the entry array.

Assuming REPONSE_JSON_OBJECT is already a parsed JSONObject.

REPONSE_JSON_OBJECT.getJSONObject("result")
    .getJSONObject("map")
    .getJSONArray("entry");

L = ['apple','red','apple','red','red','pear']
d = {}
[d.__setitem__(item,1+d.get(item,0)) for item in L]
print d 

Gives {'pear': 1, 'apple': 2, 'red': 3}

Don't forget to add android:scrollbars="vertical" along with android:fadeScrollbars="false" or it won't show at all in some cases.

Deprecated answer (Spring Data JPA <=1.6.x):

@Modifying annotation to the rescue. You will need to provide your custom SQL behaviour though.

public interface UserRepository extends JpaRepository<User, Long> {
    @Modifying
    @Query("delete from User u where u.firstName = ?1")
    void deleteUsersByFirstName(String firstName);
}

Update:

In modern versions of Spring Data JPA (>=1.7.x) query derivation for delete, remove and count operations is accessible.

public interface UserRepository extends CrudRepository<User, Long> {

    Long countByFirstName(String firstName);

    Long deleteByFirstName(String firstName);

    List<User> removeByFirstName(String firstName);

}

Why always trying to use complex words?

A layer = a part of your code, if your application is a cake, this is a slice.

A tier = a physical machine, a server.

A tier hosts one or more layers.

Example of layers:

• Presentation layer = usually all the code related to the User Interface
• Data Access layer = all the code related to your database access

Tier:

Your code is hosted on a server = Your code is hosted on a tier.

Your code is hosted on 2 servers = Your code is hosted on 2 tiers.

For example, one machine hosting the Web Site itself (the Presentation layer), another machine more secured hosting all the more security sensitive code (real business code - business layer, database access layer, etc.).

There are so many benefits to implement a layered architecture. This is tricky and properly implementing a layered application takes time. If you have some, have a look at this post from Microsoft: http://msdn.microsoft.com/en-gb/library/ee658109.aspx

One can also do this with a compact version of @TomAugspurger's answer, like so:

df = df1.merge(df2, how='left', on=['Year', 'Week', 'Colour']).merge(df3[['Week', 'Colour', 'Val3']], how='left', on=['Week', 'Colour'])

If you want to map objects to something (in this case a property). I think Array.prototype.map is what you're looking for if you want to code functionally.

[
  {name: "Joe", age: 22},
  {name: "Kevin", age: 24},
  {name: "Peter", age: 21}
].map(function(elem){
    return elem.name;
}).join(",");

In modern JavaScript:

[
  {name: "Joe", age: 22},
  {name: "Kevin", age: 24},
  {name: "Peter", age: 21}
].map(e => e.name).join(",");

(fiddle)

If you want to support older browsers, that are not ES5 compliant you can shim it (there is a polyfill on the MDN page above). Another alternative would be to use underscorejs's pluck method:

var users = [
      {name: "Joe", age: 22},
      {name: "Kevin", age: 24},
      {name: "Peter", age: 21}
    ];
var result = _.pluck(users,'name').join(",")

this worked for me:

Private Function arrIsEmpty(arr as variant)
    On Error Resume Next
    arrIsEmpty = False
    arrIsEmpty = IsNumeric(UBound(arr))
End Function

In your last block you have a comma after 'lang', followed immediately with a function. This is not valid json.

EDIT

It appears that the readme was incorrect. I had to to pass an array with the string 'twitter'.

var converter = new Showdown.converter({extensions: ['twitter']}); converter.makeHtml('whatever @meandave2020'); // output "<p>whatever <a href="http://twitter.com/meandave2020">@meandave2020</a></p>" 

I submitted a pull request to update this.

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

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

let passcode = "secret passcode";

class Employee {
    private _fullName: string;

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

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

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

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

If you are using bootstrap.min.css for carousel-

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

Open the bootstrap.min.css file and find the property "glyphicon-chevron-right" and add the property "color:red"

Solution

echo $person->middleName ?? 'Person does not have a middle name';

To show how this would look in an if statement for more clarity on how this is working.

if($person->middleName ?? false) {
    echo $person->middleName;
} else {
    echo 'Person does not have a middle name';
}

Explanation

The traditional PHP way to check for something's existence is to do:

if(isset($person->middleName)) {
    echo $person->middleName;
} else {
    echo 'Person does not have a middle name';
}

OR for a more class specific way:

if(property_exists($person, 'middleName')) {
    echo $person->middleName;
} else {
    echo 'Person does not have a middle name';
}

These are both fine in long form statements but in ternary statements they become unnecessarily cumbersome like so:

isset($person->middleName) ? echo $person->middleName : echo 'Person does not have a middle name';

You can also achieve this with just the ternary operator like so:

echo $person->middleName ?: 'Person does not have a middle name';

But... if the value does not exist (is not set) it will raise an E_NOTICE and is not best practise. If the value is null it will not raise the exception.

Therefore ternary operator to the rescue making this a neat little answer:

echo $person->middleName ?? 'Person does not have a middle name';

The os.exec*() functions replace the current programm with the new one. When this programm ends so does your process. You probably want os.system().

Click on View/Show Symbol/Show All Character - to show the [SOH] characters in the file Click on the [SOH] symbol in the file CTRL=H to bring up the replace Leave the 'Find What:' as is Change the 'Replace with:' to the character of your choosing (comma,semicolon, other...) Click 'Replace All' Done and done!

boolean flag = true;
while(flag) {
    s = s.replaceAll(" ", "");
    if (!s.contains(" "))
        flag = false;
}
return s;

Your sp_test: Return fullname

USE [MY_DB]
GO

IF (OBJECT_ID('[dbo].[sp_test]', 'P') IS NOT NULL)
DROP PROCEDURE [dbo].sp_test;
GO

CREATE PROCEDURE [dbo].sp_test 
@name VARCHAR(20),
@last_name VARCHAR(30),
@full_name VARCHAR(50) OUTPUT
AS

SET @full_name = @name + @last_name;

GO

In your sp_main

...
DECLARE @my_name VARCHAR(20);
DECLARE @my_last_name VARCHAR(30);
DECLARE @my_full_name VARCHAR(50);
...

EXEC sp_test @my_name, @my_last_name, @my_full_name OUTPUT;
...

If you're not opposed to using a libray, http://underscorejs.org/ has an intersection method, which can simplify this:

var _ = require('underscore');

var target = [ 'apple', 'orange', 'banana'];
var fruit2 = [ 'apple', 'orange', 'mango'];
var fruit3 = [ 'mango', 'lemon', 'pineapple'];
var fruit4 = [ 'orange', 'lemon', 'grapes'];

console.log(_.intersection(target, fruit2)); //returns [apple, orange]
console.log(_.intersection(target, fruit3)); //returns []
console.log(_.intersection(target, fruit4)); //returns [orange]

The intersection function will return a new array with the items that it matched and if not matches it returns empty array.

I am not a linux guru, but I believe you want to pipe your list of output files to xargs rm -rf. I have used something like this in the past with good results. Test on a sample directory first!

EDIT - I might have misunderstood, based on the other answers that are appearing. If you can use wildcards, great. I assumed that your original list that you displayed was generated by a program to give you your "selection", so I thought piping to xargs would be the way to go.

From the ansible docs: If a required variable has not been set, you can skip or fail using Jinja2’s defined test. For example:

tasks:

- shell: echo "I've got '{{ foo }}' and am not afraid to use it!"
  when: foo is defined

- fail: msg="Bailing out. this play requires 'bar'"
  when: bar is not defined

So in your case, when: deployed_revision is not defined should work

If you are lazy to check on each third party SDK if they use or not the IDFA you can use this command:
fgrep -R advertisingIdentifier . (don't forget the dot at the end of the command)

Go to your project/workspace folder and run the command to find which files are using the advertising identifier.

Then you just have to look in the guidelines of those SDKs to see what you need to do about the IDFA.

This answer is actually taken from Scott Allen's course titled ASP.NET MVC 5 Fundamentals. I thought I'd share because I think it is slightly simpler and more intuitive than any of the answers here already. Also note according to Scott Allen and other trainings I've done, find method is an optimized way to retrieve a resource from database that can use caching if it already has been retrieved. In this code, collection refers to a DBSet of objects. Object can be any generic object type.

        var object = context.collection.Find(id);  
        context.collection.Remove(object);
        context.SaveChanges();

Try:

rm -rf node_modules && npm install

Wiping node_modules first, often tends to fix a lot of weird, package related issues like that in Node.

Binary to Decimal

int(binaryString, 2)

Decimal to Binary

format(decimal ,"b")

To get rid of the white color you have to set the background-color to transparent:

button {
  font-size: 18px;
  border: 2px solid #AD235E;
  border-radius: 100px;
  width: 150px;
  height: 150px;
  background-color: transparent; /* like this */
}

Finally, I solved it. Even though the solution is a bit lengthy, I think its the simplest. The solution is as follows:

1. Install Visual Studio 2008
2. Install the service Package 1 (SP1)
3. Install SQL Server 2008 r2

here is my example:

if(userAnswer==="Yes"||"yes"||"YeS"){
 console.log("Too Bad!");   
}

This says that if the answer is Yes yes or YeS than the same thing will happen

Another implementation allowing strings like "FFF" or "FFFFFF" and using alpha:

+ (UIColor *) colorFromHexString:(NSString *)hexString alpha: (CGFloat)alpha{
    NSString *cleanString = [hexString stringByReplacingOccurrencesOfString:@"#" withString:@""];
    if([cleanString length] == 3) {
        cleanString = [NSString stringWithFormat:@"%@%@%@%@%@%@",
                       [cleanString substringWithRange:NSMakeRange(0, 1)],[cleanString substringWithRange:NSMakeRange(0, 1)],
                       [cleanString substringWithRange:NSMakeRange(1, 1)],[cleanString substringWithRange:NSMakeRange(1, 1)],
                       [cleanString substringWithRange:NSMakeRange(2, 1)],[cleanString substringWithRange:NSMakeRange(2, 1)]];
    }
    if([cleanString length] == 6) {
        cleanString = [cleanString stringByAppendingString:@"ff"];
    }

    unsigned int baseValue;
    [[NSScanner scannerWithString:cleanString] scanHexInt:&baseValue];

    float red = ((baseValue >> 24) & 0xFF)/255.0f;
    float green = ((baseValue >> 16) & 0xFF)/255.0f;
    float blue = ((baseValue >> 8) & 0xFF)/255.0f;

    return [UIColor colorWithRed:red green:green blue:blue alpha:alpha];
}

You can use functions in pyspark.sql.functions: functions like year, month, etc

refer to here: https://spark.apache.org/docs/latest/api/python/pyspark.sql.html#pyspark.sql.DataFrame

from pyspark.sql.functions import *

newdf = elevDF.select(year(elevDF.date).alias('dt_year'), month(elevDF.date).alias('dt_month'), dayofmonth(elevDF.date).alias('dt_day'), dayofyear(elevDF.date).alias('dt_dayofy'), hour(elevDF.date).alias('dt_hour'), minute(elevDF.date).alias('dt_min'), weekofyear(elevDF.date).alias('dt_week_no'), unix_timestamp(elevDF.date).alias('dt_int'))

newdf.show()

If you're on Linux, or have cygwin available on Windows, you can run the input XML through a simple sed script that will replace <Active>True</Active> with <Active>true</Active>, like so:

cat <your XML file> | sed 'sX<Active>True</Active>X<Active>true</Active>X' | xmllint --schema -

If you're not, you can still use a non-validating xslt pocessor (xalan, saxon etc.) to run a simple xslt transformation on the input, and only then pipe it to xmllint.

What the xsl should contain something like below, for the example you listed above (the xslt processor should be 2.0 capable):

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
    <xsl:output method="xml" indent="yes"/>
    <xsl:template match="/">
    <xsl:for-each select="XML">
        <xsl:for-each select="Active">
            <xsl:value-of select=" replace(current(), 'True','true')"/>
        </xsl:for-each>
    </xsl:for-each>
    </xsl:template>
</xsl:stylesheet>

$timeFirst  = strtotime('2011-05-12 18:20:20');
$timeSecond = strtotime('2011-05-13 18:20:20');
$differenceInSeconds = $timeSecond - $timeFirst;

You will then be able to use the seconds to find minutes, hours, days, etc.

This is a fix for people who are not using maven. You also need to add standard.jar to your lib folder for the core tag library to work. Works for jstl version 1.1.

<%@taglib prefix="core" uri="http://java.sun.com/jsp/jstl/core"%>

I've tested a good product for that: AlwaysUp. Not free but they have a 30 days trial period so you can give it a try...

Why Server.Transfer? Response.Redirect(Request.RawUrl) would get you what you need.

Check the error_reporting, display_errors and display_startup_errors settings in your php.ini file. They should be set to E_ALL and "On" respectively (though you should not use display_errors on a production server, so disable this and use log_errors instead if/when you deploy it). You can also change these settings (except display_startup_errors) at the very beginning of your script to set them at runtime (though you may not catch all errors this way):

error_reporting(E_ALL);
ini_set('display_errors', 'On');

After that, restart server.

Take a peek at the man page for sort...

   -n, --numeric-sort
          compare according to string numerical value

So here is an example...

sort -n filename

I've tried many of the above solutions but none of them felt flexible or satisfying.

This little hack with max-width: 1px can be applied directly to the td element

.truncated-cell {
   max-width: 1px;
   white-space: nowrap;
   overflow: hidden;
   text-overflow: ellipsis;
 }

Simply put ..

const user = {
  firstName: 'john'
};

// Factory
const addLastNameFactory = (user, lastName) => ({
  ...user,
  lastName,
});

console.log(addLastNameFactory(user, 'doe'));

// Service
const addLastNameService = (user, lastName) => {
  user.lastName = lastName; // BAD! Mutation
  return user;
};

console.log(addLastNameService(user, 'doe'));

With Java 8+ you can use Stream API:

boolean areAllDistinct(List<Block> blocksList) {
    return blocksList.stream().map(Block::getNum).distinct().count() == blockList.size();
}

Posting what was in the question body as CW answer.

Wanted to share the results, mainly derived from following camickr's link. Basically I need to throw a WindowEvent.WINDOW_CLOSING at the application's event queue. Here's a synopsis of what the solution looks like

// closing down the window makes sense as a method, so here are
// the salient parts of what happens with the JFrame extending class ..

    public class FooWindow extends JFrame {
        public FooWindow() {
            setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            setBounds(5, 5, 400, 300);  // yeah yeah, this is an example ;P
            setVisible(true);
        }
        public void pullThePlug() {
                WindowEvent wev = new WindowEvent(this, WindowEvent.WINDOW_CLOSING);
                Toolkit.getDefaultToolkit().getSystemEventQueue().postEvent(wev);
        }
    }

// Here's how that would be employed from elsewhere -

    // someplace the window gets created ..
    FooWindow fooey = new FooWindow();
    ...
    // and someplace else, you can close it thusly
    fooey.pullThePlug();

Here is the most clear & intuitive way i know to allocate a dynamic 2d array in C++. Templated in this example covers all cases.

template<typename T> T** matrixAllocate(int rows, int cols, T **M)
{
    M = new T*[rows];
    for (int i = 0; i < rows; i++){
        M[i] = new T[cols];
    }
    return M;
}

... 

int main()
{
    ...
    int** M1 = matrixAllocate<int>(rows, cols, M1);
    double** M2 = matrixAllocate(rows, cols, M2);
    ...
}

I got same problem. If I run brew link --overwrite python2. There was still zsh: /usr/local/bin//fab: bad interpreter: /usr/local/opt/python/bin/python2.7: no such file or directory.

cd /usr/local/opt/
mv python2 python

Solved it! Now we can use python2 version fabric.

=== 2018/07/25 updated

There is convinient way to use python2 version fab when your os python linked to python3. .sh for your command.

# fab python2
cd /usr/local/opt
rm python
ln -s python2 python

# use the fab cli
...

# link to python3
cd /usr/local/opt
rm python
ln -s python3 python

Hope this helps.

Try this:

List<int> list = new List<int>();
list.Add(1);
list.Add(5);
list.Add(4);
list.Add(3);
list.Add(2);

foreach (var item in list.OrderByDescending(x => x))
{
    Console.WriteLine(item);                
}

One more for loop variant, looks cleaner to me than one with enumerate():

for idx in range(len(list)):
    list[idx]=... # set a new value
    # some other code which doesn't let you use a list comprehension

Use JSON classes for parsing e.g

JSONObject mainObject = new JSONObject(Your_Sring_data);
JSONObject uniObject = mainObject.getJSONObject("university");
String  uniName = uniObject.getString("name");
String uniURL = uniObject.getString("url");

JSONObject oneObject = mainObject.getJSONObject("1");

The syntax to store the command output into a variable is var=$(command).

So you can directly do:

result=$(ls -l | grep -c "rahul.*patle")

And the variable $result will contain the number of matches.

If you're looking to paginate results, use the integrated paginator, it works great!

$games = Game::paginate(30);
// $games->results = the 30 you asked for
// $games->links() = the links to next, previous, etc pages

Try this, your dot source was a little off. Edit, adding lastexitcode bits for OP.

$A = Start-Process -FilePath .\my-app\my-fle.bat -Wait -passthru;$a.ExitCode

add -WindowStyle Hidden for invisible batch.

The Default Expiration Period for Session is 20 Minutes.

You can update sessionstate and configure the minutes under timeout

<sessionState 
timeout="30">
</sessionState>

I felt that we were lacking certain kinds of sub string counting, like unsafe byte-by-byte comparisons. I put together the original poster's method and any methods I could think of.

These are the string extensions I made.

Results: CSX corresponds with CountSubstrX and CCX corresponds with CountCharX. "chr" searches a string for '_', "and" searches a string for "and", and "mlw" searches a string for "muchlongerword"

CS1 chr: 824.123ms
CS1 and: 586.1893ms
CS1 mlw: 486.5414ms
CS2 chr: 127.8941ms
CS2 and: 806.3918ms
CS2 mlw: 497.318ms
CS3 chr: 201.8896ms
CS3 and: 124.0675ms
CS3 mlw: 212.8341ms
CS4 chr: 81.5183ms
CS4 and: 92.0615ms
CS4 mlw: 116.2197ms
CC1 chr: 66.4078ms
CC2 chr: 64.0161ms
CC3 chr: 65.9013ms
CC4 chr: 65.8206ms

And finally, I had a file with 3.6 million characters. It was "derp adfderdserp dfaerpderp deasderp" repeated 100,000 times. I searched for "derp" inside the file with the above methods 100 times these results.

CS1Derp: 1501.3444ms
CS2Derp: 1585.797ms
CS3Derp: 376.0937ms
CS4Derp: 271.1663ms

So my 4th method is definitely the winner, but, realistically, if a 3.6 million character file 100 times only took 1586ms as the worse case, then all of this is quite negligible.

By the way, I also scanned for the 'd' char in the 3.6 million character file with 100 times CountSubstr and CountChar methods. Results...

CS1  d : 2606.9513ms
CS2  d : 339.7942ms
CS3  d : 960.281ms
CS4  d : 233.3442ms
CC1  d : 302.4122ms
CC2  d : 280.7719ms
CC3  d : 299.1125ms
CC4  d : 292.9365ms

The original posters method is very bad for single character needles in a large haystack according to this.

Note: All values were updated to Release version output. I accidentally forgot to build on Release mode upon the first time I posted this. Some of my statements have been amended.

Here is a much clearer way — no need for jQuery — which adds a script as the last child of <body>:

document.body.innerHTML +='<script src="mycdn.js"><\/script>'

But if you want to add and load scripts use Rocket Hazmat's method.

You can do this with background-size:

html {
    background: url(images/bg.jpg) no-repeat center center fixed; 
    background-size: cover;
}

There are a lot of values other than cover that you can set background-size to, see which one works for you: https://developer.mozilla.org/en-US/docs/Web/CSS/background-size

Spec: https://www.w3.org/TR/css-backgrounds-3/#the-background-size

It works in all modern browsers: http://caniuse.com/#feat=background-img-opts

i fixed it just this code.

local.properties

org.gradle.jvmargs=-XX\:MaxHeapSize\=512m -Xmx512m

and you should do this changing on gradle

defaultConfig {
    applicationId "yourProjectPackage"
    minSdkVersion 15
    versionCode 1
    versionName "1.0"
    targetSdkVersion 23

    multiDexEnabled true //important
}

You can use the more command. For example:

more filename.txt

Take a look at GNU utilities for Win32 or download it:

$.ajax({type:'POST', url:'www.naver.com', dataType:'text', async:false,
    complete:function(xhr, textStatus){},
    error:function(xhr, textStatus){},
    success:function( data ){
        $.ajax({type:'POST', 
            ....
            ....
            success:function(data){
                $.ajax({type:'POST',
                    ....
                    ....
            }
        }
    });

I'm sorry but I can't explain what I worte cuz I'm a Korean who can't speak even a word in english. but I think you can easily understand it.

The syntax is wrong. The typedef should be removed.

That means some packages in pip are old or not correctly installed.

1. Try checking version and then upgrading pip.Use auto remove if that works.

2. If the pip command shows an error all the time for any command or it freezes, etc.

3. The best solution is to uninstall it or remove it completely.

4. Install a fresh pip and then update and upgrade your system.

5. I have given a solution to installing pip fresh here - python: can't open file get-pip.py error 2] no such file or directory

This will solve all gulp problem

sudo npm install gulp && sudo npm install --save del && sudo gulp build

Related to importing, if you are having issues importing a file with bulk inserts and you're getting MYSQL GONE AWAY, lost connection or similar error, open your my.cnf / my.ini and temporarily set your max_allowed_packet to something large like 400M

Remember to set it back again after your import!

This problem mostly occurs due to the error in setText() method

Solution is simple put your Integer value by converting into string type as

textview.setText(Integer.toString(integer_value));

Remenber run lombok.jar as a java app, if your using windows7 open a console(cmd.exe) as adminstrator, and run C:"your java instalation"\ java -jar "lombok directory"\lombok.jar and then lombok ask for yours ides ubication.

When you killed the session, the session hangs around for a while in "KILLED" status while Oracle cleans up after it.

If you absolutely must, you can kill the OS process as well (look up v$process.spid), which would release any locks it was holding on to.

See this for more detailed info.

Its a very old question but I think it will help newbies line me who are learning python. If you have Python 3.4 or above, the pathlib library comes with the default distribution.

To use it, you just pass a path or filename into a new Path() object using forward slashes and it handles the rest. To indicate that the path is a raw string, put r in front of the string with your actual path.

For example,

from pathlib import Path

dataFolder = Path(r'D:\Desktop dump\example.txt')

The error means that your are trying to look up JNDI name, that is not attached to any EJB component - the component with that name does not exist.

As far as dir structure is concerned: you have to create a JAR file with EJB components. As I understand you want to play with EJB 2.X components (at least the linked example suggests that) so the structure of the JAR file should be:

/com/mypackage/MyEJB.class /com/mypackage/MyEJBInterface.class /com/mypackage/etc... etc... java classes /META-INF/ejb-jar.xml /META-INF/jboss.xml

The JAR file is more or less ZIP file with file extension changed from ZIP to JAR.

BTW. If you use JBoss 5, you can work with EJB 3.0, which are much more easier to configure. The simplest component is

@Stateless(mappedName="MyComponentName")
@Remote(MyEJBInterface.class)
public class MyEJB implements MyEJBInterface{
   public void bussinesMethod(){

   }
}

No ejb-jar.xml, jboss.xml is needed, just EJB JAR with MyEJB and MyEJBInterface compiled classes.

Now in your client code you need to lookup "MyComponentName".

I had this same error message in the log. I had a UIAlertView pop up in application:didFinishLaunchingWithOptions. I solved it by delaying the call to the alertView to allow time for the root view controller to finishing loading.

In application:didFinishLaunchingWithOptions:

[self performSelector:@selector(callPopUp) withObject:nil afterDelay:1.0];

which calls after 1 second:

- (void)callPopUp
{
    // call UIAlertView
}

I think you want a code beautifier, this one looks quick and easy: http://jsbeautifier.org/

this is the javascript to display google map by passing your longitude and latitude.

        mapTypeId: google.maps.MapTypeId.ROADMAP
      }
      var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);

      document.body.appendChild(script);
    }

    window.onload = loadScript;

You can't easily decrypt the password from the hash string that you see. You should rather replace the hash string with a new one from a password that you do know.

There's a good howto here:

https://jakebillo.com/wordpress-phpass-generator-resetting-or-creating-a-new-admin-user/

Basically:

1. generate a new hash from a known password using e.g. http://scriptserver.mainframe8.com/wordpress_password_hasher.php, as described in the above link, or any other product that uses the phpass library,
2. use your DB interface (e.g. phpMyAdmin) to update the user_pass field with the new hash string.

If you have more users in this WordPress installation, you can also copy the hash string from one user whose password you know, to the other user (admin).

None of these solutions worked for me. The only workaround I could find was, adding all the min-width sizes together and applying that to the entire table. This obviously only works if you know all the column sizes in advanced, which I do. My tables look something like this:

var columns = [
  {label: 'Column 1', width: 80 /* plus other column config */},
  {label: 'Column 2', minWidth: 110 /* plus other column config */},
  {label: 'Column 3' /* plus other column config */},
];

const minimumTableWidth = columns.reduce((sum, column) => {
  return sum + (column.width || column.minWidth || 0);
}, 0);

tableElement.style.minWidth = minimumTableWidth + 'px';

This is an example and not recommended code. Fit the idea to your requirements. For example, the above is javascript and won't work if the user has JS disabled, etc.

Since it isn't practical to put code in a comment, in response to your comment in Eric's answer that it's not working for you...

I just ran the following on a SQL 2005 box (sorry, no 2000 handy) with default settings and it worked without error:

CREATE TABLE dbo.Test_Identity_Insert
(
    id  INT IDENTITY NOT NULL,
    my_string   VARCHAR(20) NOT NULL,
    CONSTRAINT PK_Test_Identity_Insert PRIMARY KEY CLUSTERED (id)
)
GO

INSERT INTO dbo.Test_Identity_Insert VALUES ('test')
GO

SELECT * FROM dbo.Test_Identity_Insert
GO

Are you perhaps sending the ID value over in your values list? I don't think that you can make it ignore the column if you actually pass a value for it. For example, if your table has 6 columns and you want to ignore the IDENTITY column you can only pass 5 values.

Have you tried the =DateValue() function?

To include time value, just add the functions together:

=DateValue(A1)+TimeValue(A1)

I personally use an about:blank src and deal with the broken image icon by setting the opacity of the img element to 0.

Hi you can try below methods with initialize of model.

Here you can initialize ng-model of textbox two way

- With use of ng-init

- With use of $scope in js

<!doctype html>
 <html >

        <title>Angular js initalize with ng-init and scope</title>
        <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.8/angular.min.js"></script>
</head>
<body ng-app="app" >
    <h3>Initialize value with ng-init</h3>
    <!-- Initlialize model values with ng-init -->
    <div ng-init="user={fullname:'Bhaskar Bhatt',email:'[email protected]',address:'Ahmedabad'};">
        Name : <input type="text" ng-model="user.fullname" /><br/>
        Email : <input type="text" ng-model="user.email" /><br/>
        Address:<input type="text" ng-model="user.address" /><br/>

    </div>  
    <!-- initialize with js controller scope -->
    <h3>Initialize with js controller</h3>

    <div  ng-controller="alpha">
        Age:<input type="text" name="age" ng-model="user.age" /><br/>

        Skills : <input type="text" name="skills" ng-model="user.skills" /><br/>
    </div>  

</body> 
<script type="text/javascript">
        angular.module("app",[])
        .controller("alpha",function($scope){
            $scope.user={};
            $scope.user.age=27;
            $scope.user.exp="4+ years";
            $scope.user.skills="Php,javascript,Jquery,Ajax,Mysql";
        });

     </script>

netstat -ano|grep 443|grep LISTEN

will tell you whether a process is listening on port 443 (you might have to replace LISTEN with a string in your language, though, depending on your system settings).

On Ubuntu, you can set proxy by using

export http_proxy=http://username:password@proxy:port
export https_proxy=http://username:password@proxy:port

or if you are having SOCKS error use

export all_proxy=http://username:password@proxy:port

Then run pip

sudo -E pip3 install {packageName}

Clear your whatsapp data and cache (or use another whatsapp) !

Android Phone : Go to SETTINGS > APPS > Application List > WhatsApp > Storage and Clear Data.

Be careful ! Backup your messages before this action.

Then the result : before and after clearing data and cache WhatsApp

The import line should be:

import React, { Component }  from 'react';

Note the uppercase R for React.

As you described, you will need to use a different method based on different versions of iOS. If your team is using both Xcode 5 (which doesn't know about any iOS 8 selectors) and Xcode 6, then you will need to use conditional compiling as follows:

#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 80000
if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) {
    // use registerUserNotificationSettings
} else {
    // use registerForRemoteNotificationTypes:
}
#else
// use registerForRemoteNotificationTypes:
#endif

If you are only using Xcode 6, you can stick with just this:

if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) {
    // use registerUserNotificationSettings
} else {
    // use registerForRemoteNotificationTypes:
}

The reason is here is that the way you get notification permissions has changed in iOS 8. A UserNotification is a message shown to the user, whether from remote or from local. You need to get permission to show one. This is described in the WWDC 2014 video "What's New in iOS Notifications"

You can use "accept" attribute as a filter in the file select box. Using "accept" help you filter input files base on their "suffix" or their "meme type"

1.Filter based on suffix: Here "accept" attribute just allow to select files with .jpeg extension.

<input type="file" accept=".jpeg" />

2.Filter based on "file type" Here "accept" attribute just allow to select file with "image/jpeg" type.

<input type="file" accept="image/jpeg" />

Important: We can change or delete the extension of a file, without changing the meme type. For example it is possible to have a file without extension, but the type of this file can be "image/jpeg". So this file can not pass the accept=".jpeg" filter. but it can pass accept="image/jpeg".

3.We can use * to select all kind of a file type. For example below code allow to select all kind of images. for example "image/png" or "image/jpeg" or ... . All of them are allowed.

<input type="file" accept="image/*" /> 

4.We can use cama ( , ) as an "or operator" in select attribute. For example to allow all kind of images or pdf files we can use this code:

<input type="file" accept="image/* , application/pdf" />

I'm surprised no one has mentioned echo and print as points of security exploitation.

Cross-Site Scripting (XSS) is a serious security exploit, because it's even more common than server-side code execution exploits.

First of all, you can't import fonts to CSS that way.

You can add this code in HTML head:

<link href='http://fonts.googleapis.com/css?family=Oswald:400,300,700' rel='stylesheet' type='text/css'>

or to import it in CSS file like this:

@import url("http://fonts.googleapis.com/css?family=Oswald:400,300,700");

Then, in your css, you can edit the body's font-family:

body {
  font-family: 'Oswald', sans-serif !important;
}

The usual way is to use uuencode for the attachments and echo for the body:

(uuencode output.txt output.txt; echo "Body of text") | mailx -s 'Subject' [email protected]

For Solaris and AIX, you may need to put the echo statement first:

(echo "Body of text"; uuencode output.txt output.txt) | mailx -s 'Subject' [email protected]

public static bool IsBalanced(string input)
    {
        Dictionary<char, char> bracketPairs = new Dictionary<char, char>() {
        { '(', ')' },
        { '{', '}' },
        { '[', ']' },
        { '<', '>' }
    };

        Stack<char> brackets = new Stack<char>();

        try
        {
            // Iterate through each character in the input string
            foreach (char c in input)
            {
                // check if the character is one of the 'opening' brackets
                if (bracketPairs.Keys.Contains(c))
                {
                    // if yes, push to stack
                    brackets.Push(c);
                }
                else
                    // check if the character is one of the 'closing' brackets
                    if (bracketPairs.Values.Contains(c))
                    {
                        // check if the closing bracket matches the 'latest' 'opening' bracket
                        if (c == bracketPairs[brackets.First()])
                        {
                            brackets.Pop();
                        }
                        else
                            // if not, its an unbalanced string
                            return false;
                    }
                    else
                        // continue looking
                        continue;
            }
        }
        catch
        {
            // an exception will be caught in case a closing bracket is found, 
            // before any opening bracket.
            // that implies, the string is not balanced. Return false
            return false;
        }

        // Ensure all brackets are closed
        return brackets.Count() == 0 ? true : false;
    }

UPDATE: This is wrong answer, but it's still useful to understand why it's wrong. See comments.

How about unicode-escape?

>>> d = {1: "??? ????", 2: u"??? ????"}
>>> json_str = json.dumps(d).decode('unicode-escape').encode('utf8')
>>> print json_str
{"1": "??? ????", "2": "??? ????"}

This one might works for you....

void List<Integer> makeSequence(int begin, int end) {

  AtomicInteger ai=new AtomicInteger(begin);
  List<Integer> ret = new ArrayList(end-begin+1);

  while ( end-->begin) {

    ret.add(ai.getAndIncrement());

  }
  return ret;  
}

stop your application...or stop your slave so no new rows are being added

create table <new table> like <old table>;
insert <new table> select * from <old table>;
truncate table  <old table>;
insert <old table> select * from <new table>;

restart your server or slave

Assuming MySQL (EDIT: posted before the SQL variant was supplied):

ALTER TABLE myTable ADD myNewColumn VARCHAR(255) AFTER myOtherColumn

The AFTER keyword tells MySQL where to place the new column. You can also use FIRST to flag the new column as the first column in the table.

Just uncomment below line from RouteServiceProvider (If does not exists then add)

protected $namespace = 'App\\Http\\Controllers';

Just download minimum prefered SDK from SDK Manager, then build. Works for me.

I have similar problem. Spring 4 and Tomcat 8. I solve the problem with Spring configuration

<bean id="dataSource" class="org.apache.tomcat.jdbc.pool.DataSource" destroy-method="close">
    <property name="initialSize" value="10" />
    <property name="maxActive" value="25" />
    <property name="maxIdle" value="20" />
    <property name="minIdle" value="10" />
     ...
    <property name="testOnBorrow" value="true" />
    <property name="validationQuery" value="SELECT 1" />
 </bean>

I have tested. It works well! This two line does everything in order to reconnect to database:

<property name="testOnBorrow" value="true" />
<property name="validationQuery" value="SELECT 1" />

When you set 64-bit the resulting binary is a "Fat" binary, which contains all three Mach-O images bundled with a thin fat header. You can see that using otool or jtool. You can check out some fat binaries included as part of the iOS 7.0 SDK, for example the AVFoundation Framework, like so:

% cd  /Developer/Platforms/iPhoneOS.platform/DeviceSupport/7.0\ \(11A465\)/Symbols/System/Library/Frameworks/AVFoundation.framework/

%otool -V -f AVFoundation                                                                     9:36

As for the binary itself, it uses the ARM64 bit instruction set, which is (mostly compatible with 32-bit, but) a totally different instruction set. This is especially important for graphics program (using NEON instructions and registers). Likewise, the CPU has more registers, which makes quite an impact on program speed. There's an interesting discussion in http://blogs.barrons.com/techtraderdaily/2013/09/19/apple-the-64-bit-question/?mod=yahoobarrons on whether or not this makes a difference; benchmarking tests have so far clearly indicated that it does.

Using otool -tV will dump the assembly (if you have XCode 5 and later), and then you can see the instruction set differences for yourself. Most (but not all) developers will remain agnostic to the changes, as for the most part they do not directly affect Obj-C (CG* APIs notwithstanding), and have to do more with low level pointer handling. The compiler will work its magic and optimizations.

Doom Emacs users, I hope you've scrolled this far or searched for 'doom' on the page...

• Doom Emacs breaks the vanilla Emacs redo shortcut: C-g C-/ C-/ C-/ etc (or C-g C-_ C-_ C-_ etc) ...and instead that just keeps undoing.
• Doom Emacs also breaks the undo-tree redo shortcut mentioned in one of the other answers as being useful for spacemacs etc: S-C-/ (AKA C-?) ...and instead that throws the error "C-? is not defined".

What you need is:

• to be in evil-mode (C-z to toggle in and out of evil-mode) (in evil-mode should see blue cursor, not orange cursor) and
• to be in 'command mode' AKA 'normal mode' (as opposed to 'insert mode') (Esc to switch to command mode) (should see block cursor, not line cursor), and then it's
• u for undo and
• C-r for redo

Remove the course_enrollment_settings.base_price immediately after CASE:

SELECT
   CASE
    WHEN course_enrollment_settings.base_price = 0      THEN 1
    ...
    END

CASE has two different forms, as detailed in the manual. Here, you want the second form since you're using search conditions.

To complement my own answer mentioned by TSamper,

• a rebase is quite often a good idea to do before a merge, because the idea is that you integrate in your branch Y the work of the branch B upon which you will merge.
  But again, before merging, you resolve any conflict in your branch (i.e.: "rebase", as in "replay my work in my branch starting from a recent point from the branch B).
  If done correctly, the subsequent merge from your branch to branch B can be fast-forward.

• a merge directly impacts the destination branch B, which means the merges better be trivial, otherwise that branch B can be long to get back to a stable state (time for you solve all the conflicts)

the point of merging after a rebase?

In the case that I describe, I rebase B onto my branch, just to have the opportunity to replay my work from a more recent point from B, but while staying into my branch.
In this case, a merge is still needed to bring my "replayed" work onto B.

The other scenario (described in Git Ready for instance), is to bring your work directly in B through a rebase (which does conserve all your nice commits, or even give you the opportunity to re-order them through an interactive rebase).
In that case (where you rebase while being in the B branch), you are right: no further merge is needed:

A Git tree at default when we have not merged nor rebased

we get by rebasing:

That second scenario is all about: how do I get new-feature back into master.

My point, by describing the first rebase scenario, is to remind everyone that a rebase can also be used as a preliminary step to that (that being "get new-feature back into master").
You can use rebase to first bring master "in" the new-feature branch: the rebase will replay new-feature commits from the HEAD master, but still in the new-feature branch, effectively moving your branch starting point from an old master commit to HEAD-master.
That allows you to resolve any conflicts in your branch (meaning, in isolation, while allowing master to continue to evolve in parallel if your conflict resolution stage takes too long).
Then you can switch to master and merge new-feature (or rebase new-feature onto master if you want to preserve commits done in your new-feature branch).

So:

• "rebase vs. merge" can be viewed as two ways to import a work on, say, master.
• But "rebase then merge" can be a valid workflow to first resolve conflict in isolation, then bring back your work.

use List<T>. Internally it uses arrays and arrays do use contiguous memory.

We pull in content frequently from our CMS as [innerHTML]="content.title". We place the necessary classes in the application's root styles.scss file rather than in the component's scss file. Our CMS purposely strips out in-line styles so we must have prepared classes that the author can use in their content. Remember using {{content.title}} in the template will not render html from the content.

In my case was a misspelling "Custom Class" name. Make sure that you check your storyboard for the custom classes that you defined.

I never liked the key code validation. My approach was to see if the input have text (any character), confirming that the user is entering text and no other characters

$('#input').on('keyup', function() {_x000D_
    var words = $(this).val();_x000D_
    // if input is empty, remove the word count data and return_x000D_
    if(!words.length) {_x000D_
        $(this).removeData('wcount');_x000D_
        return true;_x000D_
    }_x000D_
    // if word count data equals the count of the input, return_x000D_
    if(typeof $(this).data('wcount') !== "undefined" && ($(this).data('wcount') == words.length)){_x000D_
        return true;_x000D_
    }_x000D_
    // update or initialize the word count data_x000D_
    $(this).data('wcount', words.length);_x000D_
    console.log('user tiped ' + words);_x000D_
    // do you stuff..._x000D_

Here is my take: these functions convert a UTF8 string to a proper HEX without the extra zeroes padding. A real UTF8 string has characters with 1, 2, 3 and 4 bytes length.

While working on this I found a couple key things that solved my problems:

1. str.split('') doesn't handle multi-byte characters like emojis correctly. The proper/modern way to handle this is with Array.from(str)
2. encodeURIComponent() and decodeURIComponent() are great tools to convert between string and hex. They are pretty standard, they handle UTF8 correctly.
3. (Most) ASCII characters (codes 0 - 127) don't get URI encoded, so they need to handled separately. But c.charCodeAt(0).toString(16) works perfectly for those

    function utf8ToHex(str) {
      return Array.from(str).map(c => 
        c.charCodeAt(0) < 128 ? c.charCodeAt(0).toString(16) : 
        encodeURIComponent(c).replace(/\%/g,'').toLowerCase()
      ).join('');
    },
    function hexToUtf8: function(hex) {
      return decodeURIComponent('%' + hex.match(/.{1,2}/g).join('%'));
    }

There's a much better way to add conditional validation rules in MVC3; have your model inherit IValidatableObject and implement the Validate method:

public class Person : IValidatableObject
{
    public string Name { get; set; }
    public bool IsSenior { get; set; }
    public Senior Senior { get; set; }

    public IEnumerable<ValidationResult> Validate(ValidationContext validationContext) 
    { 
        if (IsSenior && string.IsNullOrEmpty(Senior.Description)) 
            yield return new ValidationResult("Description must be supplied.");
    }
}

here you go

var str = "['abc',['def','ghi'],'jkl']";
//'[\'abc\',[\'def\',\'ghi\'],\'jkl\']'
str.replace(/[\[\]']/g,'' );
//'abc,def,ghi,jkl'

In my case the database had ran out of disk space. Which caused it to not respond. Once I cleared up that issue everything worked again.

Now require-dev is enabled by default, for local development you can do composer install and composer update without the --dev option.

When you want to deploy to production, you'll need to make sure composer.lock doesn't have any packages that came from require-dev.

You can do this with

composer update --no-dev

Once you've tested locally with --no-dev you can deploy everything to production and install based on the composer.lock. You need the --no-dev option again here, otherwise composer will say "The lock file does not contain require-dev information".

composer install --no-dev

Note: Be careful with anything that has the potential to introduce differences between dev and production! I generally try to avoid require-dev wherever possible, as including dev tools isn't a big overhead.

Try this:

<EditText
        android:id="@+id/edit_text"
        android:layout_width="match_parent"
        android:layout_height="150dp"
        android:inputType="text|textMultiLine"
        android:gravity="top"/>

Here's how do to it with the SSDB catalog that was introduced with SQL Server 2012...

using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.Data.SqlClient;

using Microsoft.SqlServer.Management.IntegrationServices;

public List<string> ExecutePackage(string folder, string project, string package)
{
    // Connection to the database server where the packages are located
    SqlConnection ssisConnection = new SqlConnection(@"Data Source=.\SQL2012;Initial Catalog=master;Integrated Security=SSPI;");

    // SSIS server object with connection
    IntegrationServices ssisServer = new IntegrationServices(ssisConnection);

    // The reference to the package which you want to execute
    PackageInfo ssisPackage = ssisServer.Catalogs["SSISDB"].Folders[folder].Projects[project].Packages[package];

    // Add a parameter collection for 'system' parameters (ObjectType = 50), package parameters (ObjectType = 30) and project parameters (ObjectType = 20)
    Collection<PackageInfo.ExecutionValueParameterSet> executionParameter = new Collection<PackageInfo.ExecutionValueParameterSet>();

    // Add execution parameter (value) to override the default asynchronized execution. If you leave this out the package is executed asynchronized
    executionParameter.Add(new PackageInfo.ExecutionValueParameterSet { ObjectType = 50, ParameterName = "SYNCHRONIZED", ParameterValue = 1 });

    // Add execution parameter (value) to override the default logging level (0=None, 1=Basic, 2=Performance, 3=Verbose)
    executionParameter.Add(new PackageInfo.ExecutionValueParameterSet { ObjectType = 50, ParameterName = "LOGGING_LEVEL", ParameterValue = 3 });

    // Add a project parameter (value) to fill a project parameter
    executionParameter.Add(new PackageInfo.ExecutionValueParameterSet { ObjectType = 20, ParameterName = "MyProjectParameter", ParameterValue = "some value" });

    // Add a project package (value) to fill a package parameter
    executionParameter.Add(new PackageInfo.ExecutionValueParameterSet { ObjectType = 30, ParameterName = "MyPackageParameter", ParameterValue = "some value" });

    // Get the identifier of the execution to get the log
    long executionIdentifier = ssisPackage.Execute(false, null, executionParameter);

    // Loop through the log and do something with it like adding to a list
    var messages = new List<string>();
    foreach (OperationMessage message in ssisServer.Catalogs["SSISDB"].Executions[executionIdentifier].Messages)
    {
        messages.Add(message.MessageType + ": " + message.Message);
    }

    return messages;
}

When you define different build configurations in your visual studio solution for your projects using a tool like ConfigurationTransform, you may want your Teamcity build, to build you a specified build configuration. You may have build configurations e.g., Debug, Release, Dev, UAT, Prod etc defined. This means, you will have MSBuild Configuration transformation setup for the different configurations. These different configurations are usually used when you have different configurations, e.g. different database connection strings, for the different environment. This is very common because you would have a different database for your production environment from your playground development environment.

They say a picture is worth a thousand words, please see the image below how you would specify multiple build configurations in Teamcity.

In the commandline input text box, specify as below

/p:OutputPath=Publish;Configuration=Dev

Here, I have specified two commandline build configurations/arguments OutputPath and build Configuration with values Publish and Dev respectively, but it could have been, UAT or Prod configuration. If you want more, simply separate them by semi-colon,;

first to list the commits use

git log --oneline

then find the SHA of the commit (Message), then I used

 git log --stat 8zad24d

(8zad24d) is the SHA assosiated with the commit you are intrested in (the first couples sha example (8zad24d) you can select 4 char or 6 or 8 or the entire sha) to find the right info

The parent of the row is not the object you think, this is what I understand from the error.
Try detecting the parent of the row first, then you can be sure what to write into getElementById part of the parent.

You can use

$('#li_from_date').appendDtpicker({
    "dateOnly": true,
    "autodateOnStart": false,
    "dateFormat": "DD/MM/YYYY",
    "closeOnSelected": true,
    "futureonly": true
});

If a point is inside a rectangle. On a plane. For mathematician or geodesy (GPS) coordinates

• Let the rectangle be set by vertices A, B, C, D. The point is P. Coordinates are rectangular: x, y.
• Lets prolong the sides of the rectangle. So we have 4 straight lines l_AB, l_BC, l_CD, l_DA, or, for shortness, l₁, l₂, l₃, l₄.

• Make an equation for every l_i. The equation sort of:

  f_i(P)=0.

P is a point. For points, belonging to l_i, the equation is true.

• We need the functions on the left sides of the equations. They are f₁, f₂, f₃, f₄.
• Notice, that for every point from one side of l_i the function f_i is greater than 0, for points from the other side f_i is lesser than 0.
• So, if we are checking for P being in rectangle, we only need for the p to be on correct sides of all four lines. So, we have to check four functions for their signs.
• But what side of the line is the correct one, to which the rectangle belongs? It is the side, where lie the vertices of rectangle that don't belong to the line. For checking we can choose anyone of two not belonging vertices.

• So, we have to check this:

  f_AB(P) f_AB(C) >= 0

  f_BC(P) f_BC(D) >= 0

  f_CD(P) f_CD(A) >= 0

  f_DA(P) f_DA(B) >= 0

The unequations are not strict, for if a point is on the border, it belongs to the rectangle, too. If you don't need points on the border, you can change inequations for strict ones. But while you work in floating point operations, the choice is irrelevant.

• For a point, that is in the rectangle, all four inequations are true. Notice, that it works also for every convex polygon, only the number of lines/equations will differ.

• The only thing left is to get an equation for a line going through two points. It is a well-known linear equation. Let's write it for a line AB and point P:

  f_AB(P)   =   (x_A-x_B) (y_P-y_B) - (y_A-y_B) (x_P-x_B)

The check could be simplified - let's go along the rectangle clockwise - A, B, C, D, A. Then all correct sides will be to the right of the lines. So, we needn't compare with the side where another vertice is. And we need check a set of shorter inequations:

f_AB(P) >= 0

f_BC(P) >= 0

f_CD(P) >= 0

f_DA(P) >= 0

But this is correct for the normal, mathematician (from the school mathematics) set of coordinates, where X is to the right and Y to the top. And for the geodesy coordinates, as are used in GPS, where X is to the top, and Y is to the right, we have to turn the inequations:

f_AB(P) <= 0

f_BC(P) <= 0

f_CD(P) <= 0

f_DA(P) <= 0

If you are not sure with the directions of axes, be careful with this simplified check - check for one point with the known placement, if you have chosen the correct inequations.

git pull origin develop

Since pulling a branch into another directly merges them together

Another option to undo changes that weren't staged for commit is to run:

git restore <file>

To discard changes in the working directory.

Another approach to put the below line only when require to get data from server,Append the below line along with your ajax url.

'?_='+Math.round(Math.random()*10000)

$('.tabDisable').on('keydown', function(e)
{ 
  if (e.keyCode == 9)  
  {
    e.preventDefault();
  }
});

Put .tabDisable to all tab disable DIVs Like

<div class='tabDisable'>First Div</div> <!-- Tab Disable Div -->
<div >Second Div</div> <!-- No Tab Disable Div -->
<div class='tabDisable'>Third Div</div> <!-- Tab Disable Div -->

If none of the other solutions work for you, it's worth investigating the source of the problem. It may be than an npm module directly inserts ES6 code, which cannot be transpiled.

In my case I had the

SCRIPT1002: Syntax error vendor.js (114536,27) at the following line:

const ucs2encode = array => String.fromCodePoint(...array);

I searched the node_modules folder and found from which file the line came. It turned out that the culprit was punycode.js which in it's 2.1.0 version uses ES6 directly.

After I downgraded it to 1.4.1, which uses ES5, the problem was solved.

Just this!

$(function () {
    $('#date').datetimepicker({
         format: 'H:m',
    });

});

i use v4 and work well!!

Try the HTML code: •

A bit late but I thought I'd share in case it helps anyone: what is most likely the problem is simply that your Debug Console (the command line window that opens when run your project if it is a Windows Console Application) is still open from the last time you ran the code. Just close that window, then rebuild and run: Ctrl + B and F5, respectively.

update 
  table1 t1
set
  (
    t1.column1, 
    t1.column2
      ) = (
    select
      t2.column1, 
      t2.column2
    from
      table2  t2
    where
      t2.column1 = t1.column1
     )
    where exists (
      select 
        null
      from 
        table2 t2
      where 
        t2.column1 = t1.column1
      );

Or this (if t2.column1 <=> t1.column1 are many to one and anyone of them is good):

update 
  table1 t1
set
  (
    t1.column1, 
    t1.column2
      ) = (
    select
      t2.column1, 
      t2.column2
    from
      table2  t2
    where
      t2.column1 = t1.column1
    and
      rownum = 1    
     )
    where exists (
      select 
        null
      from 
        table2 t2
      where 
        t2.column1 = t1.column1
      ); 

Just thought i'd share this with anyone who needs more clarity on how to achieve this:

myCanvas is a Canvas control and Parent to all other controllers. This code works to neatly resize to any resolution from 1366 x 768 upward. Tested up to 4k resolution 4096 x 2160

Take note of all the MainWindow property settings (WindowStartupLocation, SizeToContent and WindowState) - important for this to work correctly - WindowState for my user case requirement was Maximized

The accepted answer work when you have a single line string(the email) but if you have a

multiline string, the error will remain.

Please look into this matter:

<!-- start: definition-->
@{
    dynamic item = new System.Dynamic.ExpandoObject();
    item.MultiLineString = @"a multi-line
                             string";
    item.SingleLineString = "a single-line string";
}
<!-- end: definition-->
<a href="#" onclick="Getinfo('@item.MultiLineString')">6/16/2016 2:02:29 AM</a>
<script>
    function Getinfo(text) {
        alert(text);
    }
</script>

Change the single-quote(') to backtick(`) in Getinfo as bellow and error will be fixed:

<a href="#" onclick="Getinfo(`@item.MultiLineString`)">6/16/2016 2:02:29 AM</a>

You can use the Bean Comparator to sort on any property in your custom class.

Cookie[] cookies = request.getCookies();
if(cookies!=null)
for (int i = 0; i < cookies.length; i++) {
 cookies[i].setMaxAge(0);
}

did that not worked? This removes all cookies if response is send back.

in my case, I Edit my gradle.properties :

note: if u enable the minifyEnabled true :

remove this line :

android.enableR8=true

and add this lines in ur build.gradle , android block :

  dexOptions {
        incremental = true
        preDexLibraries = false
        javaMaxHeapSize "4g" // 2g should be also OK
    }

hope this help some one :)

Please change small "mm" month to capital "MM" it will work.for reference below is the sample code.

        Date myDate = new Date();
        SimpleDateFormat sm = new SimpleDateFormat("MM-dd-yyyy");
       
        String strDate = sm.format(myDate);
        
        Date dt = sm.parse(strDate);
        System.out.println(strDate);

You can set the timezone on you AppServicesProvider in Provider Folder

public function boot()
{
    Schema::defaultStringLength(191);
    date_default_timezone_set('Africa/Lagos');
}

and then use Import Carbon\Carbon and simply use Carbon::now() //To get the current time, if you need to format it check out their documentation for more options based on your preferences enter link description here

This worked for me

FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
        if(tag.equalsIgnoreCase("dashboard")){

            DashboardFragment dashboardFragment = (DashboardFragment)
                    fragmentManager.findFragmentByTag("dashboard");
            if(dashboardFragment!=null) ft.show(dashboardFragment);

            ShowcaseFragment showcaseFragment = (ShowcaseFragment)
                    fragmentManager.findFragmentByTag("showcase");
            if(showcaseFragment!=null) ft.hide(showcaseFragment);

        } else if(tag.equalsIgnoreCase("showcase")){
            DashboardFragment dashboardFragment = (DashboardFragment)
                    fragmentManager.findFragmentByTag("dashboard");
            if(dashboardFragment!=null) ft.hide(dashboardFragment);

            ShowcaseFragment showcaseFragment = (ShowcaseFragment)
                    fragmentManager.findFragmentByTag("showcase");
            if(showcaseFragment!=null) ft.show(showcaseFragment);
        }

        ft.commit();

I was returning an empty JSON response for an AJAX call and in IE8 jQuery.isEmptyObject() was not validating correctly. I added an additional check that seems to catch it properly.

.done(function(data)
{  
    // Parse json response object
    var response = jQuery.parseJSON(data);

    // In IE 8 isEmptyObject doesn't catch the empty response, so adding additional undefined check
    if(jQuery.isEmptyObject(response) || response.length === 0)
    {
        //empty
    }
    else
    {
        //not empty
    }
});

For me, the object definitely existed and was uploaded correctly, however, its s3 url still threw the same error:

<Code>NoSuchKey</Code>
<Message>The specified key does not exist.</Message>

I found out that the reason was because my filename contained a # symbol, and I guess certain characters or symbols will also cause this error.

Removing this character and generating the new s3 url resolved my issue.

If you're using latest cross platform powershell (which you should btw) https://github.com/powershell/powershell#get-powershell, you can add single & to run parallel scripts. (Use ; to run sequentially)

In my case I needed to run 2 npm scripts in parallel: npm run hotReload & npm run dev

You can also setup npm to use powershell for its scripts (by default it uses cmd on windows).

Run from project root folder: npm config set script-shell pwsh --userconfig ./.npmrc and then use single npm script command: npm run start

"start":"npm run hotReload & npm run dev"

This can be done using CSS3 columns quite easily. Here's an example, HTML:

#limheight {_x000D_
    height: 300px; /*your fixed height*/_x000D_
    -webkit-column-count: 3;_x000D_
       -moz-column-count: 3;_x000D_
            column-count: 3; /*3 in those rules is just placeholder -- can be anything*/_x000D_
}_x000D_
_x000D_
#limheight li {_x000D_
    display: inline-block; /*necessary*/_x000D_
}

<ul id = "limheight">_x000D_
 <li><a href="">Glee is awesome 1</a></li>_x000D_

Since Git 2.7.0 Git will take exceptions into account. From the official release notes:

• Allow a later "!/abc/def" to override an earlier "/abc" that appears in the same .gitignore file to make it easier to express "everything in /abc directory is ignored, except for ...".

https://raw.githubusercontent.com/git/git/master/Documentation/RelNotes/2.7.0.txt

edit: apparently this doesn't work any more since Git 2.8.0

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

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

Use split(delimiter) to split on the comma.

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

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

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

With current methods available in Linq it looks quite ugly:

var tasks = items.Select(
    async item => new
    {
        Item = item,
        IsValid = await IsValid(item)
    });
var tuples = await Task.WhenAll(tasks);
var validItems = tuples
    .Where(p => p.IsValid)
    .Select(p => p.Item)
    .ToList();

Hopefully following versions of .NET will come up with more elegant tooling to handle collections of tasks and tasks of collections.

This will work in Python 3

import urllib.request

user_agent = 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.7) Gecko/2009021910 Firefox/3.0.7'

url = "http://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers"
headers={'User-Agent':user_agent,} 

request=urllib.request.Request(url,None,headers) #The assembled request
response = urllib.request.urlopen(request)
data = response.read() # The data u need

You can pass via GET. So if you want to pass the value foobar from PageA.php to PageB.php, call it as PageB.php?value=foobar.

In PageB.php, you can access it this way:

$value = $_GET['value'];

I always approach returning more than one result from a function by always returning an ArrayList. By using an ArrayList I can return only one item, consisting of many multiple values, mixing between Strings and Integers.

Once I have the ArrayList returned in my main sub, I simply use ArrayList.Item(i).ToString where i is the index of the value I want to return from the ArrayList

An example:

 Public Function Set_Database_Path()
        Dim Result As ArrayList = New ArrayList
        Dim fd As OpenFileDialog = New OpenFileDialog()


        fd.Title = "Open File Dialog"
        fd.InitialDirectory = "C:\"
        fd.RestoreDirectory = True
        fd.Filter = "All files (*.*)|*.*|All files (*.*)|*.*"
        fd.FilterIndex = 2
        fd.Multiselect = False


        If fd.ShowDialog() = DialogResult.OK Then

            Dim Database_Location = Path.GetFullPath(fd.FileName)

            Dim Database_Connection_Var = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=""" & Database_Location & """"

            Result.Add(Database_Connection_Var)
            Result.Add(Database_Location)

            Return (Result)

        Else

            Return (Nothing)

        End If
    End Function

And then call the Function like this:

Private Sub Main_Load()
  Dim PathArray As ArrayList

            PathArray = Set_Database_Path()
            My.Settings.Database_Connection_String = PathArray.Item(0).ToString
            My.Settings.FilePath = PathArray.Item(1).ToString
            My.Settings.Save()
End Sub

I wrote a js to display values from 0 to 100 in y-axis with a gap of 20.

This is my script.js

//x-axis_x000D_
var vehicles = ["Trucks", "Cars", "Bikes", "Jeeps"];_x000D_
_x000D_
//The percentage of vehicles of each type_x000D_
var percentage = [41, 76, 29, 50];_x000D_
_x000D_
var ctx = document.getElementById("barChart");_x000D_
var lineChart = new Chart(ctx, {_x000D_
  type: 'bar',_x000D_
  data: {_x000D_
    labels: vehicles,_x000D_
    datasets: [{_x000D_
      data: percentage,_x000D_
      label: "Percentage of vehicles",_x000D_
      backgroundColor: "#3e95cd",_x000D_
      fill: false_x000D_
    }]_x000D_
  },_x000D_
  options: {_x000D_
    scales: {_x000D_
      yAxes: [{_x000D_
        ticks: {_x000D_
          beginAtZero: true,_x000D_
          min: 0,_x000D_
          max: 100,_x000D_
          stepSize: 20,_x000D_
        }_x000D_
      }]_x000D_
    }_x000D_
  }_x000D_
});

This is the graph displayed on the web.

If the command should work with both tabs and spaces as the delimiter I would use awk:

awk '{print $100,$101,$102,$103,$104,$105}' myfile > outfile

As long as you just need to specify 5 fields it is imo ok to just type them, for longer ranges you can use a for loop:

awk '{for(i=100;i<=105;i++)print $i}' myfile > outfile

If you want to use cut, you need to use the -f option:

cut -f100-105 myfile > outfile

If the field delimiter is different from TAB you need to specify it using -d:

cut -d' ' -f100-105 myfile > outfile

Check the man page for more info on the cut command.

Bootstrap default "contextual backgrounds" helper classes to change the background color:

.bg-primary
.bg-default
.bg-info
.bg-warning
.bg-danger

If you need set custom background color then, you can write your own custom classes in style.css( a custom css file) example below

.bg-pink
{
  background-color: #CE6F9E;
}

An easier way that works regardless of the OS is to do

git rm -r --cached .
git add .
git commit -m "Drop files from .gitignore"

You basically remove and re-add all files, but git add will ignore the ones in .gitignore.

Using the --cached option will keep files in your filesystem, so you won't be removing files from your disk.

Note: Some pointed out in the comments that you will lose the history of all your files. I tested this with git 2.27.0 on MacOS and it is not the case. If you want to check what is happening, check your git diff HEAD~1 before you push your commit.

Here's a quick way to get what is happening:

When you did the following:

name? : string

You were saying to TypeScript it was optional. Nevertheless, when you did:

let name1 : string = person.name; //<<<Error here 

You did not leave it a choice. You needed to have a Union on it reflecting the undefined type:

let name1 : string | undefined = person.name; //<<<No error here 

Using your answer, I was able to sketch out the following which is basically, an Interface, a Class and an Object. I find this approach simpler, never mind if you don't.

// Interface
interface iPerson {
    fname? : string,
    age? : number,
    gender? : string,
    occupation? : string,
    get_person?: any
}

// Class Object
class Person implements iPerson {
    fname? : string;
    age? : number;
    gender? : string;
    occupation? : string;
    get_person?: any = function () {
        return this.fname;
    }
}

// Object literal
const person1 : Person = {
    fname : 'Steve',
    age : 8,
    gender : 'Male',
    occupation : 'IT'  
}

const p_name: string | undefined = person1.fname;

// Object instance 
const person2: Person = new Person();
person2.fname = 'Steve';
person2.age = 8;
person2.gender = 'Male';
person2.occupation = 'IT';

// Accessing the object literal (person1) and instance (person2)
console.log('person1 : ', p_name);
console.log('person2 : ', person2.get_person());

You can use the .forEach() method of JavaScript for looping through JSON.

var datesBooking = [_x000D_
    {"date": "04\/24\/2018"},_x000D_
      {"date": "04\/25\/2018"}_x000D_
    ];_x000D_
    _x000D_
    datesBooking.forEach(function(data, index) {_x000D_
      console.log(data);_x000D_
    });

To start your node in PST time zone , use following command in ubuntu.

TZ=\"/usr/share/zoneinfo/GMT+0\" && export TZ && npm start &

Then You can refer Date Library to get the custom calculation date and time functions in node.

To use it client side refer this link, download index.js and assertHelper.js and include that in your HTML.

<script src="assertHelper.js"></script>
<script type="text/javascript" src="index.js"></script>
$( document ).ready(function() {
    DateLibrary.getDayOfWeek(new Date("2015-06-15"),{operationType:"Day_of_Week"}); // Output : Monday
}

You can use different functions as given in examples to get custom dates.

If first day of week is Sunday, what day will be on 15th June 2015.

 DateLibrary.getDayOfWeek(new Date("2015-06-15"),
    {operationType:"Day_Number_of_Week",
        startDayOfWeek:"Sunday"}) // Output : 1

If first day of week is Tuesday, what week number in year will be follow in 15th June 2015 as one of the date.

 DateLibrary.getWeekNumber(new Date("2015-06-15"),
    {operationType:"Week_of_Year",
        startDayOfWeek:"Tuesday"}) // Output : 24

Refer other functions to fulfill your custom date requirements.

display:block;

then you've got a block element and the margin is added to all lines.

While it's true that a span is semantically not a block element, there are cases where you don't have control of the pages DOM. This answer is inteded for those.

See sys.exit. That function will quit your program with the given exit status.

Array manipulations are really slow compared to simple string concat. Of course, benchmark for your use case.

function(string, length, pad_char, append) {
    string = string.toString();
    length = parseInt(length) || 1;
    pad_char = pad_char || ' ';

    while (string.length < length) {
        string = append ? string+pad_char : pad_char+string;
    }
    return string;
};

Many of the mentioned examples (e.g. git diff 15dc8^!, or git diff 15dc8^..15dc8) don't work if you are using zsh and have extendedglob option set. You can fix it by one of the following three ways:

1. unsetopt extendedglob (and/or remove it from .zshrc)

2. setopt NO_NOMATCH (and/or set it in .zshrc)

3. escape the caret and bang every time with a backslash, e.g. git diff 15dc8\^\!

For those who don't want to create any models, use the following code:

var result = JsonConvert.DeserializeObject<
  List<Dictionary<string, 
    Dictionary<string, string>>>>(content);

Note: This doesn't work for your JSON string. This is not a general solution for any JSON structure.

Use this:

return JavaScript(alert("Hello this is an alert"));

or:

return Content("<script language='javascript' type='text/javascript'>alert('Thanks for Feedback!');</script>");

This works for deleting all the directories and files within a directory.

#include <iostream>
#include <cstring>
#include <cstdlib>
using namespace std;
int main()
{
    cout << "Enter the DirectoryName to Delete : ";
    string directoryName;
    cin >> directoryName;
    string a = "rmdir /s /q " + directoryName;
    system(a.c_str());
    return 0;
}

The angle between each of your points is going to be 2Pi/x so you can say that for points n= 0 to x-1 the angle from a defined 0 point is 2nPi/x.

Assuming your first point is at (r,0) (where r is the distance from the centre point) then the positions relative to the central point will be:

rCos(2nPi/x),rSin(2nPi/x)

Try

#include <inttypes.h>
...

printf("i [ %zu ] k [ %"PRIu32" ]\n", i, k);

The z represents an integer of length same as size_t, and the PRIu32 macro, defined in the C99 header inttypes.h, represents an unsigned 32-bit integer.

Read the file $AS/standalone/deployments/README.txt

• you have two different modes : auto-deploy mode and manual deploy mode
• for the manual deploy mode you have to placed a marker files as described in the others posts

• for the autodeploy mode : This is done via the "auto-deploy" attributes on the deployment-scanner element in the standalone.xml configuration file:

  <deployment-scanner scan-interval="5000" relative-to="jboss.server.base.dir"
  path="deployments" auto-deploy-zipped="true" **auto-deploy-exploded="true"**/>
  

function alphaOnly(event) {
  var key = event.keyCode;
  return ((key >= 65 && key <= 90) || key == 8);
};

or

function lettersOnly(evt) {
       evt = (evt) ? evt : event;
       var charCode = (evt.charCode) ? evt.charCode : ((evt.keyCode) ? evt.keyCode :
          ((evt.which) ? evt.which : 0));
       if (charCode > 31 && (charCode < 65 || charCode > 90) &&
          (charCode < 97 || charCode > 122)) {
          alert("Enter letters only.");
          return false;
       }
       return true;
     }

As of BeautifulSoup 4+ ,

If you have a single class name , you can just pass the class name as parameter like :

mydivs = soup.find_all('div', 'class_name')

Or if you have more than one class names , just pass the list of class names as parameter like :

mydivs = soup.find_all('div', ['class1', 'class2'])

Don't do it. Don't mess with the user's browser. By Copy + Pasting into an E-Mail confirmation field, the user accepts responsibility over what they type. If they are dumb enough to copy + paste a faulty address (it has happened to me) then it's their own damn fault.

If you want to make sure that the E-Mail confirmation works out, have the user check their E-Mail while your site waits ("Please open your webmail program in a new window"). Show the E-Mail address in big fat letters ("The confirmation E-Mail was sent to.... made an error? CLick here to change).

Even better, if you can, let the user have some kind of limited access without confirming. That way, they can log in straight away and you improve your chances to keep in touch with the visitor even if the confirmation mail is blocked due to other reasons (e.g. spam filters).

One more jQuery solution

For a single stylesheet with id "css" try this:

$('#css').replaceWith('<link id="css" rel="stylesheet" href="css/main.css?t=' + Date.now() + '"></link>');

Wrap it in a function that has global scrope and you can use it from the Developer Console in Chrome or Firebug in Firefox:

var reloadCSS = function() {
  $('#css').replaceWith('<link id="css" rel="stylesheet" href="css/main.css?t=' + Date.now() + '"></link>');
};

i had the same problem and i found that Microsoft has a systable that shows dependencies.

SELECT 
    referenced_id
    , referenced_entity_name AS table_name
    , referenced_minor_name as column_name
    , is_all_columns_found
FROM sys.dm_sql_referenced_entities ('dbo.Proc1', 'OBJECT'); 

And this works with both Views and Triggers.

Let me share what I end up with, which allows to set correctly width or height by getting the image dimensions. In addition, the code allows to fetch a loading image while the large image data we need is being transfered:

1. Use static method Image.prefetch to have the image downloaded and available to cache.

2. Use static method Image.getSize to collect height and width and use it to compute an aspect ratio and then the final height (or width)

3. Display image with a default style to your prefered width (The height will be computed with aspect ratio kept)

    function ImageX(props: {source: string, id: string})
    {
      const [imageHeight, setImageHeight] = React.useState(1);
      Image.prefetch(props.source)
      .then(() => {
          Image.getSize(props.source, (width, height) => {
            let aspectRatio =  height/width;
            setImageHeight(aspectRatio*Dimensions.get('window').width);
          });
      })
      .catch(error => console.log(error))
      if (imageHeight <=1) //Image not in cache (disk) yet
        {
          return (
            <Image key={props.id} style={styleimg.image} source={{uri: 'http://www.dsdsd/loaderpreview.gif'}}/>
          );
      }
      else
      {
        return (
          <Image key={props.id} style={styleimg.image} height={imageHeight} source={{uri: props.source}}/>
        );
      }
    }
   

   const styleimg = StyleSheet.create({ image: { width: Dimensions.get('window').width, resizeMode: 'contain' //... // you can set a height defaults } });

This solution allows you to add space in-between the images as well. It combines the best parts of all the existing solutions and doesn't add any ugly table borders.

<p align="center">
  <img alt="Light" src="https://...light.png" width="45%">
&nbsp; &nbsp; &nbsp; &nbsp;
  <img alt="Dark" src="https://...dark.png" width="45%">
</p>

The key is adding the   non-breaking space HTML entities, which you can add and remove in order to customize the spacing.

You can see this example live on GitHub here.

I use

Click <a nohref style="cursor:pointer;color:blue;text-decoration:underline"
onClick="alert('Hello World')">HERE</a>

A long way around but it gets the job done. use an A style to simplify then it becomes:

<style> A {cursor:pointer;color:blue;text-decoration:underline; } </style> 
<a nohref onClick="alert('Hello World')">HERE</a>

This can be done in WebKit-based browsers (such as Chrome and Safari) with only CSS:

::-webkit-scrollbar {
    width: 2em;
    height: 2em
}
::-webkit-scrollbar-button {
    background: #ccc
}
::-webkit-scrollbar-track-piece {
    background: #888
}
::-webkit-scrollbar-thumb {
    background: #eee
}?

Just to give a short, working example to see an effect of their difference

new Thread(foo).Start();

private void foo()
{
  this.Dispatcher.BeginInvoke(DispatcherPriority.Normal,
    (ThreadStart)delegate()
    {
        myTextBox.Text = "bing";
        Thread.Sleep(TimeSpan.FromSeconds(3));
    });
  MessageBox.Show("done");
}

If use BeginInvoke, MessageBox pops simultaneous to the text update. If use Invoke, MessageBox pops after the 3 second sleep. Hence, showing the effect of an asynchronous (BeginInvoke) and a synchronous (Invoke) call.

d = dict()

or

d = {}

or

import types
d = types.DictType.__new__(types.DictType, (), {})

I created an online tool to do this. Simply paste any dependency in pom file format, and the dependency tree for that artifact is generated, based on the central maven repository.

I like this way:

set list=a;^
b;^
c;^ 
d;


for %%a in (%list%) do ( 
 echo %%a
 echo/
)

For me, best solution is to use Angular router native directives with ui-sref like:

<button ui-sref="state.name">Go!!</button>

To understand that directive and get more options visit ui-router docs at:

https://ui-router.github.io/docs/0.3.1/#/api/ui.router.state.directive:ui-sref

While this question is quite old I just want to add another possibility of doing a merge while keeping keys.

Besides adding key/values to existing arrays using the + sign you could do an array_replace.

$a = array('foo' => 'bar', 'some' => 'string');
$b = array(42 => 'answer to the life and everything', 1337 => 'leet');

$merged = array_replace($a, $b);

The result will be:

Array
(
  [foo] => bar
  [some] => string
  [42] => answer to the life and everything
  [1337] => leet
)

Same keys will be overwritten by the latter array.
There is also an array_replace_recursive, which do this for subarrays, too.

The beauty of Visual Studio Code is

Ctrl + Shift + P

Hit it and search anything you want.

In your case, hit Ctrl + Shift + P and type fold all.

You can try using my custom view, which has capability to blur the background. It does this by faking taking snapshot of the background and blur it, just like the one in Apple's WWDC code. It is very simple to use.

I also made some improvement over to fake the dynamic blur without losing the performance. The background of my view is a scrollView which scrolls with the view, thus provide the blur effect for the rest of the superview.

When you're estimating testing you need to identify the scope of your testing - are we talking unit test, functional, UAT, interface, security, performance stress and volume?

If you're on a waterfall project you probably have some overhead tasks that are fairly constant. Allow time to prepare any planning documents, schedules and reports.

For a functional test phase (I'm a "system tester" so that's my main point of reference) don't forget to include planning! A test case often needs at least as much effort to extract from requirements / specs / user stories as it will take to execute. In addition you need to include some time for defect raising / retesting. For a larger team you'll need to factor in test management - scheduling, reporting, meetings.

Generally my estimates are based on the complexity of the features being delivered rather than a percentage of dev effort. However this does require access to at least a high-level set of instructions. Years of doing testing enables me to work out that a test of a particular complexity will take x hours of effort for preparation and execution. Some tests may require extra effort for data setup. Some tests may involve negotiating with external systems and have a duration far in excess of the effort required.

In the end, though, you need to review it in the context of the overall project. If your estimate is well above that for BA or Development then there may be something wrong with your underlying assumptions.

I know this is an old topic but it's something I'm revisiting at the moment and is of perennial interest to project managers.

The automated way to do this in SQL (SQL Server) is:

declare @cols varchar(max), @query varchar(max);
SELECT  @cols = STUFF
    (
        ( 
            SELECT DISTINCT '], [' + name
            FROM sys.columns
            where object_id = (
                select top 1 object_id from sys.objects
                where name = 'MyTable'
            )
            and name not in ('ColumnIDontWant1', 'ColumnIDontWant2')
            FOR XML PATH('')
        ), 1, 2, ''
    ) + ']';

SELECT @query = 'select ' + @cols + ' from MyTable';  
EXEC (@query);

EDIT

I think the reason that your table is not responsive to start with was you did not wrap in .container, .row and .col-md-x classes like this one

<div class="container">
   <div class="row">
     <div class="col-md-12">
     <!-- or use any other number .col-md- -->
         <div class="table-responsive">
             <div class="table">
             </div>
         </div>
     </div>
   </div>
</div>

With this, you can still use <p> tags and even make it responsive.

Please see the Bootply example here

The best precision you can possibly get is through the use of the x86-only "rdtsc" instruction, which can provide clock-level resolution (ne must of course take into account the cost of the rdtsc call itself, which can be measured easily on application startup).

The main catch here is measuring the number of clocks per second, which shouldn't be too hard.

First, you have to create two animation resources in res/anim dir

slide_up.xml

<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
    android:duration="@android:integer/config_mediumAnimTime"
    android:fromYDelta="100%"
    android:interpolator="@android:anim/accelerate_interpolator"
    android:toXDelta="0">
</translate>
</set>

slide_bottom.xml

<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate 
    android:duration="@android:integer/config_mediumAnimTime" 
    android:fromYDelta="0%p" 
    android:interpolator="@android:anim/accelerate_interpolator" 
    android:toYDelta="100%p">
</translate>
</set>

then you have to create a style

<style name="DialogAnimation">
    <item name="android:windowEnterAnimation">@anim/slide_up</item>
    <item name="android:windowExitAnimation">@anim/slide_bottom</item>
</style>

and add this line to your class

dialog.getWindow().getAttributes().windowAnimations = R.style.DialogAnimation; //style id

Based in http://www.devexchanges.info/2015/10/showing-dialog-with-animation-in-android.html

this might work for you...

$('.trhideclass1').hide();

<tr class="trhideclass1">
  <td>Label</td>
  <td>InputFile</td>
</tr>

Even more numpy

np.square(np.subtract(A, B)).mean()

I think you mean SqlServer but on Oracle you have a hard limit how many IN elements you can specify: 1000.

Throwing an exception is the best way of dealing with constructor failure. You should particularly avoid half-constructing an object and then relying on users of your class to detect construction failure by testing flag variables of some sort.

On a related point, the fact that you have several different exception types for dealing with mutex errors worries me slightly. Inheritance is a great tool, but it can be over-used. In this case I would probably prefer a single MutexError exception, possibly containing an informative error message.

It looks like you're trying to replace the extension with the following code:

if (myFile[-4:] == ".asm"):
    newFile = myFile[:4]+".hack"

However, you appear to have the array indexes mixed up. Try the following:

if (myFile[-4:] == ".asm"):
    newFile = myFile[:-4]+".hack"

Note the use of -4 instead of just 4 in the second line of code. This explains why your program is trying to create /Use.hack, which is the first four characters of your file name (/Use), with .hack appended to it.

You can use Guava's Strings.repeat method:

String existingString = ...
existingString += Strings.repeat("foo", n);

Download the Print.js from http://printjs.crabbly.com/

$http({
    url: "",
    method: "GET",
    headers: {
        "Content-type": "application/pdf"
    },
    responseType: "arraybuffer"
}).success(function (data, status, headers, config) {
    var pdfFile = new Blob([data], {
        type: "application/pdf"
    });
    var pdfUrl = URL.createObjectURL(pdfFile);
    //window.open(pdfUrl);
    printJS(pdfUrl);
    //var printwWindow = $window.open(pdfUrl);
    //printwWindow.print();
}).error(function (data, status, headers, config) {
    alert("Sorry, something went wrong")
});

There is a solution to this that does not require to specify the path of the jar file inside the .bat. This means the jar can be moved around in the filesystem with no changes, as long as the .bat file is always located in the same directory as the jar. The .bat code is:

java -jar %~dp0myjarfile.jar %*

Basically %0 would expand to the .bat full path, and %~dp0 expands to the .bat full path except the filename. So %~dp0myjarfile.jar is the full path of the myjarfile.jar colocated with the .bat file. %* will take all the arguments given to the .bat and pass it to the Java program.

I had a similar issue in Mac where svn was picking mac login as user name and I was getting error as

svn: E170013: Unable to connect to a repository at URL 'https://repo:8443/svn/proj/trunk'
svn: E175013: Access to '/svn/proj/trunk' forbidden

I used the --username along with svn command to pass the correct username which helped me. Alternatively, you can delete ~/.subversion/auth file, after which svn will prompt you for username.

You can create a thread just like this:

 Thread thread = new Thread(new Runnable() {
                    public void run() {

                       }
                    });
                thread.start();

Also, you can use Runnable, Asyntask, Timer, TimerTaks and AlarmManager to excecute Threads.

Valgrind is a nice option for Linux. Under MacOS X, you can enable the MallocDebug library which has several options for debugging memory allocation problems (see the malloc manpage, the "ENVIRONMENT" section has the relevant details). The OS X SDK also includes a tool called MallocDebug (usually installed in /Developer/Applications/Performance Tools/) that can help you to monitor usage and leaks.
