Native Node.js solution is:

const {execSync} = require('child_process');

const result = execSync('node -v'); //  this do the trick 

Just be aware that some commands returns Buffer instead of string. And if you need string just add encoding to execSync options:

const result = execSync('git rev-parse HEAD', {encoding: 'utf8'});

... and it is also good to have timeout on sync exec:

const result = execSync('git rev-parse HEAD', {encoding: 'utf8', timeout: 10000});

Normally, When you copy a cell you will find the below statement written down in the status bar (in the bottom of your sheet)

"Select destination and Press Enter or Choose Paste"

Then you press whether Enter or choose paste to paste the value of the cell.

If you didn't press Esc afterwards you will be able to paste the value of the cell several times

Application.CutCopyMode = False does the same like the Esc button, if you removed it from your code you will find that you are able to paste the cell value several times again.

And if you closed the Excel without pressing Esc you will get the warning 'There is a large amount of information on the Clipboard....'

Now days I believe it's preferred to use a function form of typeof() so...

if(filename === undefined || typeof(filename) !== "string" || filename === "") {
   console.log("no filename aborted.");
   return;
}

Also after React v 16.8+ you have an ability to use hooks

import React, {useState} from 'react';

const ControlledInputs = () => {
  const [firstName, setFirstName] = useState(false);

  const handleSubmit = (e) => {
    e.preventDefault();
    if (firstName) {
      console.log('firstName :>> ', firstName);
    }
  };

  return (
    <>
      <form onSubmit={handleSubmit}>
          <label htmlFor="firstName">Name: </label>
          <input
            type="text"
            id="firstName"
            name="firstName"
            value={firstName}
            onChange={(e) => setFirstName(e.target.value)}
          />
        <button type="submit">add person</button>
      </form>
    </>
  );
};

I was getting the same error when trying to copy a file. Closing a channel associated with the target file solved the problem.

Path destFile = Paths.get("dest file");
SeekableByteChannel destFileChannel = Files.newByteChannel(destFile);
//...
destFileChannel.close();  //removing this will throw java.nio.file.AccessDeniedException:
Files.copy(Paths.get("source file"), destFile);

The maximum size for an int is 2147483647. You could use an Int64/Long which is far larger.

In Typescript and ES6 you can also use for..of:

for (var product of products) {
     console.log(product.product_desc)
}

which will be transcoded to javascript:

for (var _i = 0, products_1 = products; _i < products_1.length; _i++) {
    var product = products_1[_i];
    console.log(product.product_desc);
}

bash to get file name

fspec="/exp/home1/abc.txt" 
filename="${fspec##*/}"  # get filename
dirname="${fspec%/*}" # get directory/path name

other ways

awk

$ echo $fspec | awk -F"/" '{print $NF}'
abc.txt

sed

$ echo $fspec | sed 's/.*\///'
abc.txt

using IFS

$ IFS="/"
$ set -- $fspec
$ eval echo \${${#@}}
abc.txt

Although you ask about numpy arrays, you can get the same behavior for regular Python lists by using operator.itemgetter.

>>> from operator import itemgetter
>>> a = [0,88,26,3,48,85,65,16,97,83,91]
>>> ind_pos = [1, 5, 7]
>>> print itemgetter(*ind_pos)(a)
(88, 85, 16)

use

startDate: '-0d'

Like

$("#datepicker").datepicker({
    startDate: '-0d',
    changeMonth: true
});

I have very simple way to do this. It worked out perfect for me.

Dictionary<string, string> types = new Dictionary<string, string>();

types.Add("1", "one");
types.Add("2", "two");
types.Add("3", "three");

Console.WriteLine("Please type a key to show its value: ");
string rLine = Console.ReadLine();

if(types.ContainsKey(rLine))
{
    string value_For_Key = types[rLine];
    Console.WriteLine("Value for " + rLine + " is" + value_For_Key);
}

That is a pretty standard use case for apply():

R> vec <- 1:10
R> DF <- data.frame(start=c(1,3,5,7), end=c(2,6,7,9))
R> DF$newcol <- apply(DF,1,function(row) mean(vec[ row[1] : row[2] ] ))
R> DF
  start end newcol
1     1   2    1.5
2     3   6    4.5
3     5   7    6.0
4     7   9    8.0
R> 

You can also use plyr if you prefer but here is no real need to go beyond functions from base R.

You can use jQuery plugin with the inview event like this :

jQuery('.your-class-here').one('inview', function (event, visible) {
    if (visible == true) {
      //Enjoy !
    }
});

A quick tip that tripped me up: if you're invoking the linker as "gcc" or "g++", then using "--start-group" and "--end-group" won't pass those options through to the linker -- nor will it flag an error. It will just fail the link with undefined symbols if you had the library order wrong.

You need to write them as "-Wl,--start-group" etc. to tell GCC to pass the argument through to the linker.

The MOD keyword only exists in the DAX language (tabular dimensional queries), not TSQL

Use % instead.

Ref: Modulo

ConvertValue( System.Object o ), then you can branch out by o.GetType() result and up-cast o to the types to work with the value.

This answer comes a little bit late, but I just was in a similar need.

Observing the comments written by @ganaraj in the question, One use case I was in the need of is, passing a classname via a directive attribute to be added to a ng-repeat li tag in the template.

For example, use the directive like this:

<my-directive class2add="special-class" />

And get the following html:

<div>
    <ul>
       <li class="special-class">Item 1</li>
       <li class="special-class">Item 2</li>
    </ul>
</div>

The solution found here applied with templateUrl, would be:

app.directive("myDirective", function() {
    return {
        template: function(element, attrs){
            return '<div><ul><li ng-repeat="item in items" class="'+attrs.class2add+'"></ul></div>';
        },
        link: function(scope, element, attrs) {
            var list = element.find("ul");
        }
    }
});

Just tried it successfully with AngularJS 1.4.9.

Hope it helps.

I have developed a very simple and fast package to do this kind of update, atualiza can deal with global and project packages. In the later you can choose between the newest version or the bigger version that matches your current package.json's rule. For global packages you don't have a rule so atualiza will upgrade to newest always.

Very interesting question.

I don't see any difference w.r.t safety or versatility, since you can do the same thing with pointer or reference. I also don't think there is any visible difference in performance since references are implemented by pointers.

But I think using reference is better because it is consistent with the standard library. For example, chaining in iostream is done by reference rather than pointer.

Add bean declaration in bean.xml file or in any other configuration file . It will resolve the error

<bean  class="com.demo.dao.RailwayDao"></bean>
<bean  class="com.demo.service.RailwayService"></bean>
<bean  class="com.demo.model.RailwayReservation"></bean>

Deleting nodes from XML

            XmlDocument doc = new XmlDocument();
            doc.Load(path);
            XmlNodeList nodes = doc.SelectNodes("//Setting[@name='File1']");
            for (int i = nodes.Count - 1; i >= 0; i--)
            {
                nodes[i].ParentNode.RemoveChild(nodes[i]);
            }
            doc.Save(path);

Adding attribute to Nodes in XML

    XmlDocument originalXml = new XmlDocument();
    originalXml.Load(path);
    XmlNode menu = originalXml.SelectSingleNode("//Settings");
    XmlNode newSub = originalXml.CreateNode(XmlNodeType.Element, "Setting", null);
    XmlAttribute xa = originalXml.CreateAttribute("name");
    xa.Value = "qwerty";
    XmlAttribute xb = originalXml.CreateAttribute("value");
    xb.Value = "555";
    newSub.Attributes.Append(xa);
    newSub.Attributes.Append(xb);
    menu.AppendChild(newSub);
    originalXml.Save(path);

SQL Server has a PIVOT command that might be what you are looking for.

select * from Tag
pivot (MAX(Value) for TagID in ([A1],[A2],[A3],[A4])) as TagTime;

If the columns are not constant, you'll have to combine this with some dynamic SQL.

DECLARE @columns AS VARCHAR(MAX);
DECLARE @sql AS VARCHAR(MAX);

select @columns = substring((Select DISTINCT ',' + QUOTENAME(TagID) FROM Tag FOR XML PATH ('')),2, 1000);

SELECT @sql =

'SELECT *
FROM TAG
PIVOT 
(
  MAX(Value) 
  FOR TagID IN( ' + @columns + ' )) as TagTime;';

 execute(@sql);

I would suggest in taking a look into JWE using special algorithms which is not present in jwt.io to decrypt

Reference link: https://www.npmjs.com/package/node-webtokens

jwt.generate('PBES2-HS512+A256KW', 'A256GCM', payload, pwd, (error, token) => {
  jwt.parse(token).verify(pwd, (error, parsedToken) => {
    // other statements
  });
});

This answer may be too late or you might have already found out the way, but still, I felt it would be helpful for you and others as well.

A simple example which I have created: https://github.com/hansiemithun/jwe-example

a day is 86400 seconds.

$tomorrow = date('y:m:d', time() + 86400);

Per the Express (Version 4+) docs, you can use:

res.status(400);
res.send('None shall pass');

http://expressjs.com/4x/api.html#res.status

<=3.8

res.statusCode = 401;
res.send('None shall pass');

Find some interesting defintion:

make sure the username and email fields are not empty in the config file. and try to clone to an empty directory. these steps worked for me.

This clearly is a bad case of controller logic in a view. It would be better to do this in a controller and return the desired view.

[ChildActionOnly]
public ActionResult Results() 
{
    EnumerableRowCollection<DataRow> custs = ViewBag.Customers;
    bool anyRows = custs.Any();

    if(anyRows == false)
    {
        return View("NoResults");
    }
    else
    {
        return View("OtherView");
    }
}

Modify NoResults.cshtml to a Partial.

And call this as a Partial view in the parent view

@Html.Partial("Results")

You might have to pass the Customer collection as a model to the Result action or in a ViewDataDictionary due to reasons explained here: Can't access ViewBag in a partial view in ASP.NET MVC3

The ChildActionOnly attribute will make sure you cannot go to this page by navigating and that this view must be rendered as a partial, thus by a parent view. cfr: Using ChildActionOnly in MVC

Reflection is a language's ability to inspect and dynamically call classes, methods, attributes, etc. at runtime.

For example, all objects in Java have the method getClass(), which lets you determine the object's class even if you don't know it at compile time (e.g. if you declared it as an Object) - this might seem trivial, but such reflection is not possible in less dynamic languages such as C++. More advanced uses lets you list and call methods, constructors, etc.

Reflection is important since it lets you write programs that do not have to "know" everything at compile time, making them more dynamic, since they can be tied together at runtime. The code can be written against known interfaces, but the actual classes to be used can be instantiated using reflection from configuration files.

Lots of modern frameworks use reflection extensively for this very reason. Most other modern languages use reflection as well, and in scripting languages (such as Python) they are even more tightly integrated, since it feels more natural within the general programming model of those languages.

 <android.support.design.widget.NavigationView
        android:id="@+id/navigation_view"
        android:background="#000"
        android:layout_height="match_parent"
        android:layout_width="match_parent"
        android:layout_gravity="start"
        app:headerLayout="@layout/header"
        app:itemTextColor="your color"
        app:menu="@menu/drawer" />

you can write a stored procedure like this:

CREATE PROCEDURE sanitize_TABLE()

BEGIN

#replace space with underscore

UPDATE Table SET FieldName = REPLACE(FieldName," ","_") WHERE FieldName is not NULL;

#delete dot

UPDATE Table SET FieldName = REPLACE(FieldName,".","") WHERE FieldName is not NULL;

#delete (

UPDATE Table SET FieldName = REPLACE(FieldName,"(","") WHERE FieldName is not NULL;

#delete )

UPDATE Table SET FieldName = REPLACE(FieldName,")","") WHERE FieldName is not NULL;

#raplace or delete any char you want

#..........................

END

In this way you have modularized control over table.

You can also generalize stored procedure making it, parametric with table to sanitoze input parameter

Try

1. List all packages

android list sdk --all

2. Install packages using following command

android update sdk -u -a -t package1, package2, package3 //comma seperated packages obtained using list command 

Using Bootstrap you can do this thing like below code.

<!DOCTYPE html>

    top: 0;
    right: 0;
    min-width: 100%;
    min-height: 100%;
    font-size: 100px;
    text-align: right;
    filter: alpha(opacity=0);
    opacity: 0;
    outline: none;
    background: white;
    cursor: inherit;
    display: block;
}

UPDATE: The really awesome code posted by Gabe Sechan no longer works unless you explicitly request the user to grant the necessary permissions. Here is some code that you can place in your main activity to request these permissions:

    if (getApplicationContext().checkSelfPermission(Manifest.permission.READ_PHONE_STATE)
            != PackageManager.PERMISSION_GRANTED) {
        // Permission has not been granted, therefore prompt the user to grant permission
        ActivityCompat.requestPermissions(this,
                new String[]{Manifest.permission.READ_PHONE_STATE},
                MY_PERMISSIONS_REQUEST_READ_PHONE_STATE);
    }

    if (getApplicationContext().checkSelfPermission(Manifest.permission.PROCESS_OUTGOING_CALLS)
            != PackageManager.PERMISSION_GRANTED) {
        // Permission has not been granted, therefore prompt the user to grant permission
        ActivityCompat.requestPermissions(this,
                new String[]{Manifest.permission.PROCESS_OUTGOING_CALLS},
                MY_PERMISSIONS_REQUEST_PROCESS_OUTGOING_CALLS);
    }

ALSO: As someone mentioned in a comment below Gabe's post, you have to add a little snippet of code, android:enabled="true, to the receiver in order to detect incoming calls when the app is not currently running in the foreground:

    <!--This part is inside the application-->
    <receiver android:name=".CallReceiver" android:enabled="true">
        <intent-filter>
            <action android:name="android.intent.action.PHONE_STATE" />
        </intent-filter>
        <intent-filter>
            <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
        </intent-filter>
    </receiver>

The solution marked is not efficient. It has a O(n^2) time complexity. What we can do is to sort both lists, and the execute an intersection algorithm as the one below.

private  static ArrayList<Integer> interesect(ArrayList<Integer> f, ArrayList<Integer> s) { 
    ArrayList<Integer> res = new ArrayList<Integer>();

    int i = 0, j = 0; 
    while (i != f.size() && j != s.size()) { 

        if (f.get(i) < s.get(j)) {
            i ++;
        } else if (f.get(i) > s.get(j)) { 
            j ++;
        } else { 
            res.add(f.get(i)); 
            i ++;  j ++;
        }
    }


    return res; 
}

This one has a complexity of O(n log n + n) which is in O(n log n). The union is done in a similar manner. Just make sure you make the suitable modifications on the if-elseif-else statements.

You can also use iterators if you want (I know they are more efficient in C++, I dont know if this is true in Java as well).

Go to "Control Panel" -> "Administrative Tools" and open "Datasources (ODBC)". By default, the tab "User-DSN" will be opened, click "Add" and a dialogue will pop up:

The best HTTP header for your client to send an access token (JWT or any other token) is the Authorization header with the Bearer authentication scheme.

This scheme is described by the RFC6750.

Example:

GET /resource HTTP/1.1
Host: server.example.com
Authorization: Bearer eyJhbGciOiJIUzI1NiIXVCJ9TJV...r7E20RMHrHDcEfxjoYZgeFONFh7HgQ

If you need stronger security protection, you may also consider the following IETF draft: https://tools.ietf.org/html/draft-ietf-oauth-pop-architecture. This draft seems to be a good alternative to the (abandoned?) https://tools.ietf.org/html/draft-ietf-oauth-v2-http-mac.

Note that even if this RFC and the above specifications are related to the OAuth2 Framework protocol, they can be used in any other contexts that require a token exchange between a client and a server.

Unlike the custom JWT scheme you mention in your question, the Bearer one is registered at the IANA.

Concerning the Basic and Digest authentication schemes, they are dedicated to authentication using a username and a secret (see RFC7616 and RFC7617) so not applicable in that context.

I found too simple hack just do this add new element in AndroidManifest as:-

<activity android:name=".activityName"
          android:label="@string/app_name"
          android:noHistory="true"/>

the android:noHistory will clear your unwanted activity from Stack.

The apiKey in this configuration snippet just identifies your Firebase project on the Google servers. It is not a security risk for someone to know it. In fact, it is necessary for them to know it, in order for them to interact with your Firebase project. This same configuration data is also included in every iOS and Android app that uses Firebase as its backend.

In that sense it is very similar to the database URL that identifies the back-end database associated with your project in the same snippet: https://<app-id>.firebaseio.com. See this question on why this is not a security risk: How to restrict Firebase data modification?, including the use of Firebase's server side security rules to ensure only authorized users can access the backend services.

If you want to learn how to secure all data access to your Firebase backend services is authorized, read up on the documentation on Firebase security rules. These rules control access to file storage and database access, and are enforced on the Firebase servers. So no matter if it's your code, or somebody else's code that uses you configuration data, it can only do what the security rules allow it to do.

For another explanation of what Firebase uses these values for, and for which of them you can set quotas, see the Firebase documentation on using and managing API keys.

If you'd like to reduce the risk of committing this configuration data to version control, consider using the SDK auto-configuration of Firebase Hosting. While the keys will still end up in the browser in the same format, they won't be hard-coded into your code anymore with that.

File file = context.getFilesDir(); 
file.mkdir();
String[] array = filePath.split("/"); 
for(int t = 0; t < array.length - 1; t++) {
    file = new File(file, array[t]); 
    file.mkdir();
}
File f = new File(file,array[array.length- 1]); 
RandomAccessFileOutputStream rvalue = 
    new RandomAccessFileOutputStream(f, append);

Use the clip property along with opacity, z-index, absolute positioning, and some browser filters to place the file input over the desired button:

I had a similar problem and the solution was to do this:

#cloud-container{
    position:absolute;
    top:0;
    bottom:0;
}

I wanted a page-centered div with height 100% of page height, so my total solution was:

#cloud-container{
    position:absolute;
    top:0;
    bottom:0;
    left:0;
    right:0; 
    width: XXXpx; /*otherwise div defaults to page width*/
    margin: 0 auto; /*horizontally centers div*/
}

You might need to make a parent element (or simply 'body') have position: relative;

In this

index.delete();

            if (!index.exists())
               {
                   index.mkdir();
               }

you are calling

 if (!index.exists())
                   {
                       index.mkdir();
                   }

after

index.delete();

This means that you are creating the file again after deleting File.delete() returns a boolean value.So if you want to check then do System.out.println(index.delete()); if you get true then this means that file is deleted

File index = new File("/home/Work/Indexer1");
    if (!index.exists())
       {
             index.mkdir();
       }
    else{
            System.out.println(index.delete());//If you get true then file is deleted




            if (!index.exists())
               {
                   index.mkdir();// here you are creating again after deleting the file
               }




        }

from the comments given below,the updated answer is like this

File f=new File("full_path");//full path like c:/home/ri
    if(f.exists())
    {
        f.delete();
    }
    else
    {
        try {
            //f.createNewFile();//this will create a file
            f.mkdir();//this create a folder
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

The best solution is to get a copy of Node's type definitions. This will solve all kinds of dependency issues, not only require(). This was previously done using packages like typings, but as Mike Chamberlain mentioned, Typings are deprecated. The modern way is doing it like this:

npm install --save-dev @types/node

Not only will it fix the compiler error, it will also add the definitions of the Node API to your IDE.

In version 0.2.13, You should be able to pass objects into $state.go,

$state.go('myState', {myParam: {some: 'thing'}})

$stateProvider.state('myState', {
                url: '/myState/{myParam:json}',
                params: {myParam: null}, ...

and then access the parameter in your controller.

$stateParams.myParam //should be {some: 'thing'}

myParam will not show up in the URL.

Source:

See the comment by christopherthielen https://github.com/angular-ui/ui-router/issues/983, reproduced here for convenience:

christopherthielen: Yes, this should be working now in 0.2.13.

.state('foo', { url: '/foo/:param1?param2', params: { param3: null } // null is the default value });

$state.go('foo', { param1: 'bar', param2: 'baz', param3: { id: 35, name: 'what' } });

$stateParams in 'foo' is now { param1: 'bar', param2: 'baz', param3: { id: 35, name: 'what' } }

url is /foo/bar?param2=baz.

Can you load the GUIDs into a scratch table then do a

... WHERE var IN SELECT guid FROM #scratchtable

If you are using docker to deploy the spring boot app, you can set the profile using the flag e:

docker run -e "SPRING_PROFILES_ACTIVE=prod" -p 8080:8080 -t r.test.co/myapp:latest

Don't escape the underscore. Might be causing some whackness.

As Gary's Student mentioned, you would need to remove the dot before Cells to make the code work as you originally wrote it. I can't be sure, since you only included the one line of code, but the error you got when you deleted the dots might have something to do with how you defined your variables.

I ran your line of code with the variables defined as integers and it worked:

Sub TestClearLastColumn()

    Dim LastColData As Long
        Set LastColData = Range("A1").End(xlToRight).Column

    Dim LastRowData As Long
        Set LastRowData = Range("A1").End(xlDown).Row

    Worksheets("Sheet1").Range(Cells(2, LastColData), Cells(LastRowData, LastColData)).ClearContents

End Sub

I don't think a With statement is appropriate to the line of code you shared, but if you were to use one, the With would be at the start of the line that defines the object you are manipulating. Here is your code rewritten using an unnecessary With statement:

With Worksheets("Sheet1").Range(Cells(2, LastColData), Cells(LastRowData, LastColData))
    .ClearContents
End With

With statements are designed to save you from retyping code and to make your coding easier to read. It becomes useful and appropriate if you do more than one thing with an object. For example, if you wanted to also turn the column red and add a thick black border, you might use a With statement like this:

With Worksheets("Sheet1").Range(Cells(2, LastColData), Cells(LastRowData, LastColData))
    .ClearContents
    .Interior.Color = vbRed
    .BorderAround Color:=vbBlack, Weight:=xlThick
End With

Otherwise you would have to declare the range for each action or property, like this:

    Worksheets("Sheet1").Range(Cells(2, LastColData), Cells(LastRowData, LastColData)).ClearContents
    Worksheets("Sheet1").Range(Cells(2, LastColData), Cells(LastRowData, LastColData)).Interior.Color = vbRed
    Worksheets("Sheet1").Range(Cells(2, LastColData), Cells(LastRowData, LastColData)).BorderAround Color:=vbBlack, Weight:=xlThick

I hope this gives you a sense for why Gary's Student believed the compiler might be expecting a With (even though it was inappropriate) and how and when a With can be useful in your code.

In Visual Studio 2015 (community edition), System.Windows.Forms is not available and hence we can't use MessageBox.Show("text").

Use this Instead:

var Msg = new MessageDialog("Some String here", "Title of Message Box");    
await Msg.ShowAsync();

Note: Your function must be defined async to use above await Msg.ShowAsync().

Implement your own implementation of IValueConverter. A sample implementation is at

http://msdn.microsoft.com/en-us/library/system.windows.data.ivalueconverter.aspx

In your Convert method, have it return the values you'd like instead of the defaults.

My two cents:

a) setting navigationBar.barTintColor / titleTextAttributes do work in any view (pushed, added..and so on in init..

b) setting appearence does not work everywhere:

• You can call it on AppDelegate
• " " 1st level view
• if You call it again in subsequent pushed views, does MNOT work

SwiftUI note:

a) does not apply (no navigationBar, unless you pass via UIViewControllerRepresentable trick..) b) is valid for SwiftUI: same behaviour.

Actually you have a code compiled targeting a higher JDK (JDK 1.8 in your case) but at runtime you are supplying a lower JRE(JRE 7 or below).

you can fix this problem by adding target parameter while compilation
e.g. if your runtime target is 1.7, you should use 1.7 or below

javac -target 1.7 *.java

if you are using eclipse, you can sent this parameter at Window -> Preferences -> Java -> Compiler -> set "Compiler compliance level" = choose your runtime jre version or lower.

Sorry, but the event handler is really not needed. What you do need is another element within the tag to click on.

<a id="test1" href="javascript:alert('test1')">TEST1</a>
<a id="test2" href="javascript:alert('test2')"><span>TEST2</span></a>

Jquery:

$('#test1').trigger('click'); // Nothing
$('#test2').find('span').trigger('click'); // Works
$('#test2 span').trigger('click'); // Also Works

This is all about what you are clicking and it is not the tag but the thing within it. Unfortunately, bare text does not seem to be recognised by JQuery, but it is by vanilla javascript:

document.getElementById('test1').click(); // Works!

Or by accessing the jQuery object as an array

$('#test1')[0].click(); // Works too!!!

Here's my Code to theme the alert dialog box:

<style name="alertDialog" parent="Theme.AppCompat.Dialog.Alert">
    <item name="android:background">@color/light_button_text_color</item>
    <item name="android:textColor">@android:color/black</item>
    <item name="android:textColorPrimary">@android:color/black</item>
    <item name="android:textColorSecondary">@android:color/black</item>
    <item name="android:titleTextColor" tools:targetApi="m">@android:color/black</item>
</style>

Place this code in styles.xml. In your java apply this theme as:

AlertDialog.Builder builder = new AlertDialog.Builder(this, R.style.alertDialog);

The suggested answer only works for certain versions of ruby. Some commenters suggest using ruby-dev; that didn't work for me either.

sudo apt-get install ruby-all-dev

worked for me.

Just escape the dashes to prevent them from being interpreted (I don't think underscore needs escaping, but it can't hurt). You don't say which regex you are using.

setInterval repeats the call, setTimeout only runs it once.

dt=$(date --date yesterday "+%a %d/%m/%Y")
echo $dt

$(Split-Path "D:\Server\User\CUST\MEA\Data\In\Files\CORRECTED\CUST_MEAFile.csv" -leaf)

let's add:

int[] fastLogs;

private void populateFastLogs(int length) {
    fastLogs = new int[length + 1];
    int counter = 0;
    int log = 0;
    int num = 1;
    fastLogs[0] = 0;
    for (int i = 1; i < fastLogs.length; i++) {
        counter++;
        fastLogs[i] = log;
        if (counter == num) {
            log++;
            num *= 2;
            counter = 0;
        }
    }
}

This error is coming because existing value is getting updated immediately after getting initialized. So if you will update new value after existing value is rendered in DOM, Then it will work fine.Like mentioned in this article Angular Debugging "Expression has changed after it was checked"

for example you can use

ngOnInit() {
    setTimeout(() => {
      //code for your new value.
    });

}

or

ngAfterViewInit() {
  this.paginator.page
      .pipe(
          startWith(null),
          delay(0),
          tap(() => this.dataSource.loadLessons(...))
      ).subscribe();
}

As you can see i have not mentioned time in setTimeout method. As it is browser provided API, not a JavaScript API, So this will run seperately in browser stack and will wait till call stack items are finished.

How browser API envokes concept is explained by Philip Roberts in one of Youtube video(What the hack is event loop?).

As skaffman suggested, JSP 2.0 Tag Files are the bee's knees.

Let's take your simple example.

Put the following in WEB-INF/tags/wrapper.tag

<%@tag description="Simple Wrapper Tag" pageEncoding="UTF-8"%>
<html><body>
  <jsp:doBody/>
</body></html>

Now in your example.jsp page:

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@taglib prefix="t" tagdir="/WEB-INF/tags" %>

<t:wrapper>
    <h1>Welcome</h1>
</t:wrapper>

That does exactly what you think it does.

So, lets expand upon that to something a bit more general. WEB-INF/tags/genericpage.tag

<%@tag description="Overall Page template" pageEncoding="UTF-8"%>
<%@attribute name="header" fragment="true" %>
<%@attribute name="footer" fragment="true" %>
<html>
  <body>
    <div id="pageheader">
      <jsp:invoke fragment="header"/>
    </div>
    <div id="body">
      <jsp:doBody/>
    </div>
    <div id="pagefooter">
      <jsp:invoke fragment="footer"/>
    </div>
  </body>
</html>

To use this:

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@taglib prefix="t" tagdir="/WEB-INF/tags" %>

<t:genericpage>
    <jsp:attribute name="header">
      <h1>Welcome</h1>
    </jsp:attribute>
    <jsp:attribute name="footer">
      <p id="copyright">Copyright 1927, Future Bits When There Be Bits Inc.</p>
    </jsp:attribute>
    <jsp:body>
        <p>Hi I'm the heart of the message</p>
    </jsp:body>
</t:genericpage>

What does that buy you? A lot really, but it gets even better...

WEB-INF/tags/userpage.tag

<%@tag description="User Page template" pageEncoding="UTF-8"%>
<%@taglib prefix="t" tagdir="/WEB-INF/tags" %>
<%@attribute name="userName" required="true"%>

<t:genericpage>
    <jsp:attribute name="header">
      <h1>Welcome ${userName}</h1>
    </jsp:attribute>
    <jsp:attribute name="footer">
      <p id="copyright">Copyright 1927, Future Bits When There Be Bits Inc.</p>
    </jsp:attribute>
    <jsp:body>
        <jsp:doBody/>
    </jsp:body>
</t:genericpage>

To use this: (assume we have a user variable in the request)

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@taglib prefix="t" tagdir="/WEB-INF/tags" %>

<t:userpage userName="${user.fullName}">
  <p>
    First Name: ${user.firstName} <br/>
    Last Name: ${user.lastName} <br/>
    Phone: ${user.phone}<br/>
  </p>
</t:userpage>

But it turns you like to use that user detail block in other places. So, we'll refactor it. WEB-INF/tags/userdetail.tag

<%@tag description="User Page template" pageEncoding="UTF-8"%>
<%@tag import="com.example.User" %>
<%@attribute name="user" required="true" type="com.example.User"%>

First Name: ${user.firstName} <br/>
Last Name: ${user.lastName} <br/>
Phone: ${user.phone}<br/>

Now the previous example becomes:

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@taglib prefix="t" tagdir="/WEB-INF/tags" %>

<t:userpage userName="${user.fullName}">
  <p>
    <t:userdetail user="${user}"/>
  </p>
</t:userpage>

The beauty of JSP Tag files is that it lets you basically tag generic markup and then refactor it to your heart's content.

JSP Tag Files have pretty much usurped things like Tiles etc., at least for me. I find them much easier to use as the only structure is what you give it, nothing preconceived. Plus you can use JSP tag files for other things (like the user detail fragment above).

Here's an example that is similar to DisplayTag that I've done, but this is all done with Tag Files (and the Stripes framework, that's the s: tags..). This results in a table of rows, alternating colors, page navigation, etc:

<t:table items="${actionBean.customerList}" var="obj" css_class="display">
  <t:col css_class="checkboxcol">
    <s:checkbox name="customerIds" value="${obj.customerId}"
                onclick="handleCheckboxRangeSelection(this, event);"/>
  </t:col>
  <t:col name="customerId" title="ID"/>
  <t:col name="firstName" title="First Name"/>
  <t:col name="lastName" title="Last Name"/>
  <t:col>
    <s:link href="/Customer.action" event="preEdit">
      Edit
      <s:param name="customer.customerId" value="${obj.customerId}"/>
      <s:param name="page" value="${actionBean.page}"/>
    </s:link>
  </t:col>
</t:table>

Of course the tags work with the JSTL tags (like c:if, etc.). The only thing you can't do within the body of a tag file tag is add Java scriptlet code, but this isn't as much of a limitation as you might think. If I need scriptlet stuff, I just put the logic in to a tag and drop the tag in. Easy.

So, tag files can be pretty much whatever you want them to be. At the most basic level, it's simple cut and paste refactoring. Grab a chunk of layout, cut it out, do some simple parameterization, and replace it with a tag invocation.

At a higher level, you can do sophisticated things like this table tag I have here.

Yes, package-lock.json is intended to be checked into source control. If you're using npm 5+, you may see this notice on the command line: created a lockfile as package-lock.json. You should commit this file. According to npm help package-lock.json:

package-lock.json is automatically generated for any operations where npm modifies either the node_modules tree, or package.json. It describes the exact tree that was generated, such that subsequent installs are able to generate identical trees, regardless of intermediate dependency updates.

This file is intended to be committed into source repositories, and serves various purposes:

• Describe a single representation of a dependency tree such that teammates, deployments, and continuous integration are guaranteed to install exactly the same dependencies.

• Provide a facility for users to "time-travel" to previous states of node_modules without having to commit the directory itself.

• To facilitate greater visibility of tree changes through readable source control diffs.

• And optimize the installation process by allowing npm to skip repeated metadata resolutions for previously-installed packages.

One key detail about package-lock.json is that it cannot be published, and it will be ignored if found in any place other than the toplevel package. It shares a format with npm-shrinkwrap.json, which is essentially the same file, but allows publication. This is not recommended unless deploying a CLI tool or otherwise using the publication process for producing production packages.

If both package-lock.json and npm-shrinkwrap.json are present in the root of a package, package-lock.json will be completely ignored.

it will have some effect on an object.... query for the result of the effect. If it has no visible effect its not worth unit testing!

In my case, I was trying to build and get APK for an old Unity 3D project (so that I can play the game in my Android phone). I was using the most recent Android Studio version, and all the SDK packages I could download via SDK Manager in Android Studio. SDK Packages was located in

C:/Users/Onat/AppData/Local/Android/Sdk 

And the error message I got was the same except the JDK (Java Development Kit) version "jdk-12.0.2" . JDK was located in

C:\Program Files\Java\jdk-12.0.2

And Environment Variable in Windows was JAVA_HOME : C:\Program Files\Java\jdk-12.0.2

After 3 hours of research, I found out that Unity does not support JDK 10. As told in https://forum.unity.com/threads/gradle-build-failed-error-could-not-determine-java-version-from-10-0-1.532169/ . My suggestion is:

1. Uninstall unwanted JDK if you have one installed already. https://www.java.com/tr/download/help/uninstall_java.xml
2. Head to http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
3. Login to/Open a Oracle account if not already logged in.
4. Download the older but functional JDK 8 for your computer set-up(32 bit/64 bit, Windows/Linux etc.)
5. Install the JDK. Remember the installation path. (https://docs.oracle.com/cd/E19182-01/820-7851/inst_cli_jdk_javahome_t/)
6. If you are using Windows, Open Environment Variables and change Java Path via Right click My Computer/This PC>Properties>Advanced System Settings>Environment Variables>New>Variable Name: JAVA_HOME>Variable Value: [YOUR JDK Path, Mine was "C:\Program Files\Java\jdk1.8.0_221"]
7. In Unity 3D, press Edit > Preferences > External Tools and fill in the JDK path (Mine was "C:\Program Files\Java\jdk1.8.0_221").
8. Also, in the same pop-up, edit SDK Path. (Get it from Android Studio > SDK Manager > Android SDK > Android SDK Location.)
9. If needed, restart your computer for changes to take effect.

Based on Fedor Kazakov and others answers, I created a default config.

Error message:

Definitely Method A because its pooled and thread safe.

If you are using httpclient 4.x, the connection manager is called ThreadSafeClientConnManager. See this link for further details (scroll down to "Pooling connection manager"). For example:

    HttpParams params = new BasicHttpParams();
    SchemeRegistry registry = new SchemeRegistry();
    registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
    ClientConnectionManager cm = new ThreadSafeClientConnManager(params, registry);
    HttpClient client = new DefaultHttpClient(cm, params);

So, with Perl 5.20, the new answer is:

foreach my $key (keys $ad_grp_ref->%*) {

(which has the advantage of transparently working with more complicated expressions:

foreach my $key (keys $ad_grp_obj[3]->get_ref()->%*) {

etc.)

See perlref for the full documentation.

Note: in Perl version 5.20 and 5.22, this syntax is considered experimental, so you need

use feature 'postderef';
no warnings 'experimental::postderef';

at the top of any file that uses it. Perl 5.24 and later don't require any pragmas for this feature.

To really properly do a merge which takes only input from the branch you are merging you can do

git merge --strategy=ours ref-to-be-merged

git diff --binary ref-to-be-merged | git apply --reverse --index

git commit --amend

There will be no conflicts in any scenario I know of, you don't have to make additional branches, and it acts like a normal merge commit.

This doesn't play nice with submodules however.

sudo mv /filename /etc/init.d/
sudo chmod +x /etc/init.d/filename 
sudo update-rc.d filename defaults 

Script should now start on boot. Note that this method also works with both hard links and symbolic links (ln).

Edit

At this point in the boot process PATH isn't set yet, so it is critical that absolute paths are used throughout. BUT, as pointed out in the comments by Steve HHH, explicitly declaring the full file path (/etc/init.d/filename) for the update-rc.d command is not valid in most versions of Linux. Per the manpage for update-rc.d, the second parameter is a script located in /etc/init.d/*. Updated above code to reflect this.

Another Edit

Also as pointed out in the comments (by Charles Brandt), /filename must be an init style script. A good template was also provided - https://github.com/fhd/init-script-template.

Another link to another article just to avoid possible link rot (although it would be saddening if GitHub died) - http://www.linux.com/learn/tutorials/442412-managing-linux-daemons-with-init-scripts

yetAnother Edit

As pointed out in the comments (by Russell Yan), This works only on default mode of update-rc.d.

According to manual of update-rc.d, it can run on two modes, "the machines using the legacy mode will have a file /etc/init.d/.legacy-bootordering", in which case you have to pass sequence and runlevel configuration through command line arguments.

The equivalent argument set for the above example is

sudo update-rc.d filename start 20 2 3 4 5 . stop 20 0 1 6 .

To remove all Untrack files. Try this terminal command

 git clean -fdx

public static boolean isEmailValid(String email) {
    boolean isValid = false;

    String expression = "^[\\w\\.-]+@([\\w\\-]+\\.)+[A-Z]{2,4}$";
    CharSequence inputStr = email;

    Pattern pattern = Pattern.compile(expression, Pattern.CASE_INSENSITIVE);
    Matcher matcher = pattern.matcher(inputStr);
    if (matcher.matches()) {
        isValid = true;
    }
    return isValid;
}

I had the same issue but solved it by using !important. I forgot about the inheritance in CSS. Just a tip to check first.

According to Apple, generally disabling ATS will lead to app rejection, unless you have a good reason to do so. Even then, you should add exceptions for domains that you can access safely.

Apple has an excellent tool that tells you exactly what settings to use: In Terminal, enter

/usr/bin/nscurl --ats-diagnostics --verbose https://www.example.com/whatever

and nscurl will check whether this request fails, and then try a variety of settings and tell you exactly which one passes, and what to do. For example, for some third-party URL that I visit, this command told me that this dictionary passes:

{
    NSExceptionDomains = {
        "www.example.com" = {
            NSExceptionRequiresForwardSecrecy = false;
        };
    };
}

To distinguish between your own sites and third-party sites that are out of your control, use, for example, the key NSThirdPartyExceptionRequiresForwardSecrecy.

Update 2016:

Unfortunately most of the above solutions are out of date and no longer maintained.

There are 3 additional options I can suggest that are still actively developed:

1. BrowseEmAll.Cef

A .Net component that can be used to integrate the Chrome engine into your .Net Application. Based on CefGlue but a little faster on updates to the latest Chrome version. Also there is a commercial support option available which might come in handy for some. Of course the component itself is open source.

2. BrowseEmAll.Gecko

Another .Net component which can be used to integrate the Firefox engine into your .Net application. This is based on Geckofx but unlike the current version of Geckofx this will work with a normal release build of Firefox. To use Geckofx you will need to build Firefox yourself. Again commercial support is available but the component itself is fully open source.

3. BrowseEmAll Core API

Need all the different browsers in your .Net Application? Which the BrowseEmAll Core API you can integrate Chrome, Firefox, Webkit and Internet Explorer into your application. This is a commercial product though so be warned.

(Full disclosure: I work for this company so take everything I say with a grain of salt)

For Power-Shell

./adb shell getprop | Select-String -Pattern '(model)|(version.sdk)|(manufacturer)|(platform)|(serialno)|(product.name)|(brand)'

For linux(burrowing asnwer from @0x8BADF00D)

adb shell getprop | grep "model\|version.sdk\|manufacturer\|hardware\|platform\|revision\|serialno\|product.name\|brand"

For single string find in power shell

./adb shell getprop | Select-String -Pattern 'model'

or

./adb shell getprop | Select-String -Pattern '(model)'

For multiple

./adb shell getprop | Select-String -Pattern '(a|b|c|d)'

pep8 was recently added to PyPi.

• pep8 - Python style guide checker
• pep8 is a tool to check your Python code against some of the style conventions in PEP 8.

It is now super easy to check your code against pep8.

See http://pypi.python.org/pypi/pep8

I think you might want something like this

// Compose a string that consists of three lines.
string lines = "First line.\r\nSecond line.\r\nThird line.";

// Write the string to a file.
System.IO.StreamWriter file = new System.IO.StreamWriter("c:\\test.txt");
file.WriteLine(lines);

file.Close();

It's significantly easier to grant management permissions to a service using one of these tools:

• Group Policy
• Security Template
• subinacl.exe command-line tool.

Here's the MSKB article with instructions for Windows Server 2008 / Windows 7, but the instructions are the same for 2000 and 2003.

is_uploaded_file() is great to use, specially for checking whether it is an uploaded file or a local file (for security purposes).

However, if you want to check whether the user uploaded a file, use $_FILES['file']['error'] == UPLOAD_ERR_OK.

See the PHP manual on file upload error messages. If you just want to check for no file, use UPLOAD_ERR_NO_FILE.

Simply remove the .value from your code.

Set envFrmwrkPath = ActiveSheet.Range("D6").Value

instead of this, use:

Set envFrmwrkPath = ActiveSheet.Range("D6")

awk '{t+=length($0)}END{print t}' file3

Inside your project folder their is a bin folder. Inside your bin folder, there are 2 folders, a Release and a Debug. For your polished .exe, you want to go into your Release folder.

I'm not quite sure if thats what youre asking

1. Find the playlist/manifest with the developer tools network tab. There is always one, as that's how it works. It might have a m3u8 extension that you can type into the Filter. (The youtube-dl tool can also find the m3u8 tool automatically some time give it direct link to the webpage where the video is being displayed.)

2. Give it to the youtube-dl tool (Download) . It can download much more than just YouTube. It'll auto-download each segment then combine everything with FFmpeg then discard the parts. There is a good chance it supports the site you want to download from natively, and you don't even need to do step #1.

3. If you find a site that is stubborn and you run into 403 errors... Telerik Fiddler to the rescue. It can catch and save anything transmitted (such as the video file) as it acts as a local proxy. Everything you see/hear can be downloaded, unless it's DRM content like Spotify.

Note: in windows, you can use youtube-dl.exe using "Command Prompt" or creating a batch file. i.e

d:\youtube-dl.exe https://www.youtube.com/watch?v=gbdFOwKHil0

This might be a simple solution to achieve this:

INSERT INTO funds (ID, date, price)
SELECT 23, DATE('2013-02-12'), 22.5
  FROM dual
 WHERE NOT EXISTS (SELECT 1 
                     FROM funds 
                    WHERE ID = 23
                      AND date = DATE('2013-02-12'));

p.s. alternatively (if ID a primary key):

 INSERT INTO funds (ID, date, price)
    VALUES (23, DATE('2013-02-12'), 22.5)
        ON DUPLICATE KEY UPDATE ID = 23; -- or whatever you need

see this Fiddle.

I searched for many pages of the web through of the Google and here on the Stack Overflow, but nothing suggested resolved my problem.

After many attempts, I've changed my way of to test that controller. Then I have discovered that the problem occurs always which I reopened the page through of the Ctrl + Shift + T shortcut in Chrome. So the page ran, but without a parent window reference, and because this can't be closed.

Use the map() function native on JavaScript arrays:

var yourArray = [ {
    'id':1,
    'name':'john'
},{
    'id':2,
    'name':'jane'
}........,{
    'id':2000,
    'name':'zack'
}];

var newArray = yourArray.map( function( el ){ 
                                return el.name; 
                               });

This function will be used get the data from url in form of HttpResponse object.

public HttpResponse getRespose(String url, String your_auth_code){
HttpClient client = new DefaultHttpClient();
HttpPost postForGetMethod = new HttpPost(url);
postForGetMethod.addHeader("Content-type", "Application/JSON");
postForGetMethod.addHeader("Authorization", your_auth_code);
return client.execute(postForGetMethod);
}

Above function is called here and we receive a String form of the json using the Apache library Class.And in following statements we try to make simple pojo out of the json we received.

String jsonString     =     
EntityUtils.toString(getResponse("http://echo.jsontest.com/title/ipsum/content/    blah","Your_auth_if_you_need_one").getEntity(), "UTF-8");
final GsonBuilder gsonBuilder = new GsonBuilder();
gsonBuilder.registerTypeAdapter(JsonJavaModel .class, new    CustomJsonDeserialiser());
final Gson gson = gsonBuilder.create();
JsonElement json = new JsonParser().parse(jsonString);
JsonJavaModel pojoModel = gson.fromJson(
                    jsonElementForJavaObject, JsonJavaModel.class);

This is a simple java model class for incomming json. public class JsonJavaModel{ String content; String title; } This is a custom deserialiser:

public class CustomJsonDeserialiserimplements JsonDeserializer<JsonJavaModel>         {

@Override
public JsonJavaModel deserialize(JsonElement json, Type type,
                                 JsonDeserializationContext arg2) throws    JsonParseException {
    final JsonJavaModel jsonJavaModel= new JsonJavaModel();
    JsonObject object = json.getAsJsonObject();

    try {
     jsonJavaModel.content = object.get("Content").getAsString()
     jsonJavaModel.title = object.get("Title").getAsString()

    } catch (Exception e) {

        e.printStackTrace();
    }
    return jsonJavaModel;
}

Include Gson library and org.apache.http.util.EntityUtils;

It's work for me!

The problem is most likely because you config custom UITableViewCell in storyboard but you do not use storyboard to instantiate your UITableViewController which uses this UITableViewCell. For example, in MainStoryboard, you have a UITableViewController subclass called MyTableViewController and have a custom dynamic UITableViewCell called MyTableViewCell with identifier id "MyCell".

If you create your custom UITableViewController like this:

 MyTableViewController *myTableViewController = [[MyTableViewController alloc] init];

It will not automatically register your custom tableviewcell for you. You have to manually register it.

But if you use storyboard to instantiate MyTableViewController, like this:

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
MyTableViewController *myTableViewController = [storyboard  instantiateViewControllerWithIdentifier:@"MyTableViewController"];

Nice thing happens! UITableViewController will automatically register your custom tableview cell that you define in storyboard for you.

In your delegate method "cellForRowAtIndexPath", you can create you table view cell like this :

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"MyCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

//Configure your cell here ...

return cell;
}

dequeueReusableCellWithIdentifier will automatically create new cell for you if there is not reusable cell available in the recycling queue.

Then you are done!

Solution that works for me is adding event listener to paste event if you are pasting to a text input. Since paste event happens before text in input changes, inside my on paste handler I create a deferred function inside which I check for changes in my input box that happened on paste:

onPaste: function() {
    var oThis = this;
    setTimeout(function() { // Defer until onPaste() is done
        console.log('paste', oThis.input.value);
        // Manipulate pasted input
    }, 1);
}

Might benefit you to be aware of another option, word-wrap: break-word;

The difference here is that words that can completely fit on 1 line will do that, vs. being forced to break simply because there is no more real estate on the line the word starts on.

See the fiddle for an illustration http://jsfiddle.net/Jqkcp/

git apply --reject --whitespace=fix mychanges.patch worked for me.

Explanation

The --reject option will instruct git to not fail if it cannot determine how to apply a patch, but instead to apply indivdual hunks it can apply and create reject files (.rej) for hunks it cannot apply. Wiggle can "apply [these] rejected patches and perform word-wise diffs".

Additionally, --whitespace=fix will warn about whitespace errors and try to fix them, rather than refusing to apply an otherwise applicable hunk.

Both options together make the application of a patch more robust against failure, but they require additional attention with respect to the result.

For the whole documentation, see https://git-scm.com/docs/git-apply.

I use outline a css 2 property that simply works. Check this out, is simple and even easy to animate:

.double-border {_x000D_
  display: block;_x000D_
  clear: both;_x000D_
  background: red;_x000D_
  border: 5px solid yellow;_x000D_
  outline: 5px solid blue;_x000D_
  transition: 0.7s all ease-in;_x000D_
  height: 50px;_x000D_
  width: 50px;_x000D_
}_x000D_
.double-border:hover {_x000D_
  background: yellow;_x000D_
  outline-color: red;_x000D_
  border-color: blue;_x000D_
}

<div class="double-border"></div>

Both approaches will catch all exceptions. There is no significant difference between your two code examples except that the first will generate a compiler warning because ex is declared but not used.

But note that some exceptions are special and will be rethrown automatically.

ThreadAbortException is a special exception that can be caught, but it will automatically be raised again at the end of the catch block.

http://msdn.microsoft.com/en-us/library/system.threading.threadabortexception.aspx

As mentioned in the comments, it is usually a very bad idea to catch and ignore all exceptions. Usually you want to do one of the following instead:

• Catch and ignore a specific exception that you know is not fatal.

  catch (SomeSpecificException)
  {
      // Ignore this exception.
  }
  

• Catch and log all exceptions.

  catch (Exception e)
  {
      // Something unexpected went wrong.
      Log(e);
      // Maybe it is also necessary to terminate / restart the application.
  }
  

• Catch all exceptions, do some cleanup, then rethrow the exception.

  catch
  {
      SomeCleanUp();
      throw;
  }
  

Note that in the last case the exception is rethrown using throw; and not throw ex;.

This uses a helper batch file called repl.bat - download from: https://www.dropbox.com/s/qidqwztmetbvklt/repl.bat

Place repl.bat in the same folder as the batch file or in a folder that is on the path.

Repl.bat is a hybrid batch file using native Windows scripting and is far faster than a regular batch script.

The L switch makes the text search and replace a literal string and I'd expect the 12 MB file to complete in several seconds on a modern PC.

@echo off &setlocal
set "search=%~1"
set "replace=%~2"
set "textfile=Input.txt"
set "newfile=Output.txt"
call repl.bat "%search%" "%replace%" L < "%textfile%" >"%newfile%"
del "%textfile%"
rename "%newfile%" "%textfile%"

With ES6 you can now do it like this

Example Codepen URl to load

const iframe = '<iframe height="265" style="width: 100%;" scrolling="no" title="fx." src="//codepen.io/ycw/embed/JqwbQw/?height=265&theme-id=0&default-tab=js,result" frameborder="no" allowtransparency="true" allowfullscreen="true">See the Pen <a href="https://codepen.io/ycw/pen/JqwbQw/">fx.</a> by ycw(<a href="https://codepen.io/ycw">@ycw</a>) on <a href="https://codepen.io">CodePen</a>.</iframe>'; 

A function component to load Iframe

function Iframe(props) {
  return (<div dangerouslySetInnerHTML={ {__html:  props.iframe?props.iframe:""}} />);
}

Usage:

import React from "react";
import ReactDOM from "react-dom";
function App() {
  return (
    <div className="App">
      <h1>Iframe Demo</h1>
      <Iframe iframe={iframe} />,
    </div>
  );
}

const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);

Typescript is (a superset of) javascript, so you just use JSON.parse as you would in javascript:

let obj = JSON.parse(jsonString);

Only that in typescript you can have a type to the resulting object:

interface MyObj {
    myString: string;
    myNumber: number;
}

let obj: MyObj = JSON.parse('{ "myString": "string", "myNumber": 4 }');
console.log(obj.myString);
console.log(obj.myNumber);

(code in playground)

The simplest method to bring a resource from the classpath in the resources directory parsed into a String is the following one liner.

As a String(Using Spring Libraries):

         String resource = StreamUtils.copyToString(
                new ClassPathResource("resource.json").getInputStream(), defaultCharset());

This method uses the StreamUtils utility and streams the file as an input stream into a String in a concise compact way.

If you want the file as a byte array you can use basic Java File I/O libraries:

As a byte array(Using Java Libraries):

byte[] resource = Files.readAllBytes(Paths.get("/src/test/resources/resource.json"));

i think the problem is we are trying to connect to a local server that is not running.

we need to first run the MySQL server then connect to it.

just Go to task manager > services find MYSQL80 and then start the service.

my_string.replaceAll("\\p{C}", "?");

See more about Unicode regex. java.util.regexPattern/String.replaceAll supports them.

This is a simple way of getting the DAYS between two dates

var nites = dateDiff(arriveDate,departDate,"D");

You can do this way

   // Check if the point entered is numeric or not
   if (Int32.TryParse(txtEvDistance.Text, out var outParse))
    {
       // Do what you want to do if numeric
    }
   else
    {
       // Do what you want to do if not numeric
    }     

const units = ['bytes', 'KB', 'MB', 'GB', 'TB', 'PB', 'EB', 'ZB', 'YB'];

function niceBytes(x){

  let l = 0, n = parseInt(x, 10) || 0;

  while(n >= 1024 && ++l){
      n = n/1024;
  }
  //include a decimal point and a tenths-place digit if presenting 
  //less than ten of KB or greater units
  return(n.toFixed(n < 10 && l > 0 ? 1 : 0) + ' ' + units[l]);
}

Results:

niceBytes(435)                 // 435 bytes
niceBytes(3398)                // 3.3 KB
niceBytes(490398)              // 479 KB
niceBytes(6544528)             // 6.2 MB
niceBytes(23483023)            // 22 MB
niceBytes(3984578493)          // 3.7 GB
niceBytes(30498505889)         // 28 GB
niceBytes(9485039485039445)    // 8.4 PB

Try this:

arr = str.split (":");

I have the same issue and I did this: I went to windows option (the icon), then I chose the option Anaconda Prompt then a small windows show up with the prompt like this: c:\user\computer name> then I type this: c:\user\computer name>jupyter notebook
then enter and that's it. I hope that helps

1. You can add to .htaccess, httpd.conf or VirtualHost section
2. Header set X-Frame-Options SAMEORIGIN this is the best option

Allow from URI is not supported by all browsers. Reference: X-Frame-Options on MDN

The only thing that worked for me is deleting the project and then importing it again. Works like a charm :)

If the program was written in C# you can get the source code in almost its original form using .NET Reflector. You won't be able to see comments and local variable names, but it is very readable.

If it was written C++ it's not so easy... even if you could decompile the code into valid C++ it is unlikely that it will resemble the original source because of inlined functions and optimizations which are hard to reverse.

Please note that by reverse engineering and modifying the source code you might breaking the terms of use of the programs unless you wrote them yourself or have permission from the author.

Essentially the same as Gringo Suave's answer, but with a generator:

from datetime import datetime, timedelta


def datetime_range(start=None, end=None):
    span = end - start
    for i in xrange(span.days + 1):
        yield start + timedelta(days=i)

Then you can use it as follows:

In: list(datetime_range(start=datetime(2014, 1, 1), end=datetime(2014, 1, 5)))
Out: 
[datetime.datetime(2014, 1, 1, 0, 0),
 datetime.datetime(2014, 1, 2, 0, 0),
 datetime.datetime(2014, 1, 3, 0, 0),
 datetime.datetime(2014, 1, 4, 0, 0),
 datetime.datetime(2014, 1, 5, 0, 0)]

Or like this:

In []: for date in datetime_range(start=datetime(2014, 1, 1), end=datetime(2014, 1, 5)):
   ...:     print date
   ...:     
2014-01-01 00:00:00
2014-01-02 00:00:00
2014-01-03 00:00:00
2014-01-04 00:00:00
2014-01-05 00:00:00

If you want to set required to true

$(document).ready(function(){
$('#edit-submitted-first-name').prop('required',true);
});

if you want to set required to false

$(document).ready(function(){
$('#edit-submitted-first-name').prop('required',false);
});

select command denied to user ''@'' for table ''

This problem is a basically generated after join condition are wrong database name in your join query. So please check the your select query in join table name after database.

Then solve it for example its correct ans ware

string g = " SELECT `emptable`.`image` , `applyleave`.`id` , `applyleave`.`empid` , `applyleave`.`empname` , `applyleave`.`dateapply` , `applyleave`.`leavename` , `applyleave`.`fromdate` , `applyleave`.`todate` , `applyleave`.`resion` , `applyleave`.`contact` , `applyleave`.`leavestatus` , `applyleave`.`username` , `applyleave`.`noday` FROM `DataEMP_ems`.`applyleave` INNER JOIN `DataEMP_ems`.`emptable` ON ( `applyleave`.`empid` = `emptable`.`empid` ) WHERE ( `applyleave`.`leavestatus` = 'panding' ) ";

The join table is imputable and applyleave on the same database but online database name is diffrent then given error on this problem.

All the hidden fields in your fieldset are using the same id, so jquery is only returning the first one. One way to fix this is to create a counter variable and concatenate it to each hidden field id.

(on Windows OS without Service) Spring Boot start/stop sample.

run.bat

@ECHO OFF
IF "%1"=="start" (
    ECHO start your app name
    start "yourappname" java -jar -Dspring.profiles.active=prod yourappname-0.0.1.jar
) ELSE IF "%1"=="stop" (
    ECHO stop your app name
    TASKKILL /FI "WINDOWTITLE eq yourappname"
) ELSE (
    ECHO please, use "run.bat start" or "run.bat stop"
)
pause

start.bat

@ECHO OFF
call run.bat start

stop.bat:

@ECHO OFF
call run.bat stop

No guarantee, but I suspect IE uses the older Protected Storage API.

You need to wrap the text in a div element and include the absolutely positioned element inside of it.

<div class="container">
    <div class="inner">
        <div class="full-height"></div>
        [Your text here]
    </div>
</div>

Css:

.inner: { position: relative; height: auto; }
.full-height: { height: 100%; }

Setting the inner div's position to relative makes the absolutely position elements inside of it base their position and height on it rather than on the .container div, which has a fixed height. Without the inner, relatively positioned div, the .full-height div will always calculate its dimensions and position based on .container.

What ?

Interfaces are basically a contract that all the classes implementing the Interface should follow. They looks like a class but has no implementation.

In C# Interface names by convention is defined by Prefixing an 'I' so if you want to have an interface called shapes, you would declare it as IShapes

Now Why ?

Improves code re-usability

Lets say you want to draw Circle, Triangle. You can group them together and call them Shapesand have methods to draw Circle and Triangle But having concrete implementation would be a bad idea because tomorrow you might decide to have 2 more Shapes Rectangle & Square. Now when you add them there is a great chance that you might break other parts of your code.

With Interface you isolate the different implementation from the Contract

Live Scenario Day 1

You were asked to create an App to Draw Circle and Triangle

interface IShapes
{
   void DrawShape();
   
 }

class Circle : IShapes
{
    
    public void DrawShape()
    {
        Console.WriteLine("Implementation to Draw a Circle");
    }
}

Class Triangle: IShapes
{
     public void DrawShape()
    {
        Console.WriteLine("Implementation to draw a Triangle");
    }
}

static void Main()
{
     List <IShapes> shapes = new List<IShapes>();
        shapes.Add(new Circle());
        shapes.Add(new Triangle());

        foreach(var shape in shapes)
        {
            shape.DrawShape();
        }
}

Live Scenario Day 2

If you were asked add Square and Rectangle to it, all you have to do is create the implentation for it in class Square: IShapes and in Main add to list shapes.Add(new Square());

Check if you have "https://rubygems.org/" as a source to find gems at:

$ gem sources
*** CURRENT SOURCES ***

https://rubygems.org/

If not, you should be able to add it with

$ gem sources --add https://rubygems.org/
https://rubygems.org/ added to sources

Here are docs for the gem source command.

An easy way that is compatible pretty much everywhere is to set font-size: 0 on the container, provided you don't have any descendent text nodes you need to style (though it is trivial to override this where needed).

.nospace {
   font-size: 0;
}

jsFiddle.

You could also change from the default display: inline into block or inline-block. Be sure to use the workarounds required for <= IE7 (and possibly ancient Firefoxes) for inline-block to work.

Add /Q for quiet mode and it should remove the prompt.

If you have got a pre-commit task with husky running eslint, please continue reading. I tried most of the answers about parserOptions and parser values where my actual issue was about the node version I was using.

My current node version was 12.0.0, but husky was using my nvm default version somehow (even though I didn't have nvm in my system). This seems to be an issue with husky itself. So:

1. I deleted $HOME/.nvm folder which was not deleted when I removed nvm earlier.
2. Verified node is the latest and did proper parser options.
3. It started working!

Why do you need to get this root url ? Can't you generate directly absolute URL's ?

{{ url('_demo_hello', { 'name': 'Thomas' }) }}

This Twig code will generate the full http:// url to the _demo_hello route.

In fact, getting the base url of the website is only getting the full url of the homepage route :

{{ url('homepage') }}

(homepage, or whatever you call it in your routing file).

Just type the following commands from console.

cd /your_project
heroku restart

Most people recommend using notifyDataSetChanged(), but I found this link pretty useful. In fact using clear and add you can accomplish the same goal using less memory footprint, and more responsibe app.

For example:

notesListAdapter.clear();
notes = new ArrayList<Note>();
notesListAdapter.add(todayNote);
if (birthdayNote != null) notesListAdapter.add(birthdayNote);

/* no need to refresh, let the adaptor do its job */

I do not think that what you are looking for is provided by SciPy. I would write the code myself, in this situation.

The spline interpolation and smoothing from scipy.interpolate are quite nice and might be quite helpful in fitting peaks and then finding the location of their maximum.

You need to add else in your lambda function. Because you are telling what to do in case your condition(here x < 90) is met, but you are not telling what to do in case the condition is not met.

sample['PR'] = sample['PR'].apply(lambda x: 'NaN' if x < 90 else x) 

On Ubuntu after installing lxc-docker you need to add your user to the docker user group:

sudo usermod -a -G docker myusername

This is because of the socket file permissions:

srw-rw---- 1 root docker 0 Mar 20 07:43 /var/run/docker.sock

DO NOT RUN usermod WITHOUT "-a" as suggested in one of the other comments or it will wipe your additional groups setting and will just leave the "docker" group

This is what will happen:

?  ~  id pawel
uid=1000(pawel) gid=1000(pawel) groups=1000(pawel),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),108(lpadmin),124(sambashare),998(docker)
?  ~  usermod -G docker pawel
?  ~  id pawel               
uid=1000(pawel) gid=1000(pawel) groups=1000(pawel),998(docker)

You can treat a submodule exactly like an ordinary repository. To propagate your changes upstream just commit and push as you would normally within that directory.

Use the -v flag:

$ gem install fog -v 1.8

Here is my solution.

 if (Build.VERSION.SDK_INT >= 24) {
        holder.notificationTitle.setText(Html.fromHtml(notificationSucces.getMessage(), Html.FROM_HTML_MODE_LEGACY));
    } else {
        holder.notificationTitle.setText(Html.fromHtml(notificationSucces.getMessage()));

Many functions are vectorization already, and so there is no need for any iterations (neither for loops or *pply functions). Your testFunc is one such example. You can simply call:

  testFunc(df[, "x"], df[, "z"])

In general, I would recommend trying such vectorization approaches first and see if they get you your intended results.

Alternatively, if you need to pass multiple arguments to a function which is not vectorized, mapply might be what you are looking for:

  mapply(power.t.test, df[, "x"], df[, "z"])

You can find the relative path of a file using tree, just pipe the output to grep to filter down

tree -f | grep filename

Here is a function you can put into your .bash_profile, .bashrc, .zshrc or other...

findfile(){ tree -f | grep $1; } # $1 = filename, -f is full path

from php you can invoke jquery like this but my 2nd method is much cleaner and better for php

if($switchView) :?>
 <script>$('.container').hide();</script>
 <script>$('.confirm').show();</script>
<?php endif;

another way is to initiate your class and dynamically invoke the condition like this

$registerForm ='block'; 

then in your html use this

<div class="col" style="display: <?= $registerForm?>">

now you can play with the view with if and else easily without having a messed code example

if($condition)  registerForm = 'none'; 

Make sure you use 'block' to show and 'none' to hide. This is far the easiest way with php

I had this problem when I was trying to call a WCF service hosted in a new server from a windows application from my local. I was getting same error message and at end had this "No connection could be made because the target machine actively refused it 127.0.0.1:8888". I donot know whether I am wrong or correct but I feel whenever the server was getting request from my windows application it is routing to something else. So I did some reading and added below in Web.config of service host project. After that everything worked like a magic.

<system.net>
    <defaultProxy enabled="false">
    </defaultProxy>
</system.net>

I have experienced this exact problem and found, on the users machine, one of the libraries I depended on was marked as "MISSING" in the references dialog. In that case it was some office font library that was available in my version of Office 2007, but not on the client desktop.

The error you get is a complete red herring (as pointed out by divo).

Fortunately I wasn't using anything from the library, so I was able to remove it from the XLA references entirely. I guess, an extension of divo' suggested best practice would be for testing to check the XLA on all the target Office versions (not a bad idea in any case).

You can use the css property white-space and set it to pre-wrap to the enclosing div element.

div {
     white-space: pre-wrap;
}

To have an output more similar to the raw console.log(obj) I usually do use console.log('Status: ' + util.inspect(obj)) (JSON is slightly different).

In python strings are list of characters, but they are not explicitly list type, just list-like (i.e. it can be treated like a list). More formally, they're known as sequence (see http://docs.python.org/2/library/stdtypes.html#sequence-types-str-unicode-list-tuple-bytearray-buffer-xrange):

>>> a = 'foo bar'
>>> isinstance(a, list)
False
>>> isinstance(a, str)
True

Since strings are sequence, you can use slicing to access parts of the list, denoted by list[start_index:end_index] see Explain Python's slice notation . For example:

>>> a = [1,2,3,4]
>>> a[0]
1 # first element, NOT a sequence.
>>> a[0:1]
[1] # a slice from first to second, a list, i.e. a sequence.
>>> a[0:2]
[1, 2]
>>> a[:2]
[1, 2]

>>> x = "foo bar"
>>> x[0:2]
'fo'
>>> x[:2]
'fo'

When undefined, the slice notation takes the starting position as the 0, and end position as len(sequence).

In the olden C days, it's an array of characters, the whole issue of dynamic vs static list sounds like legend now, see Python List vs. Array - when to use?

I believe when you need this kinds of operations on your Redux state the spread operator is your friend and this principal applies for all children.

Let's pretend this is your state:

const state = {
    houses: {
        gryffindor: {
          points: 15
        },
        ravenclaw: {
          points: 18
        },
        hufflepuff: {
          points: 7
        },
        slytherin: {
          points: 5
        }
    }
}

And you want to add 3 points to Ravenclaw

const key = "ravenclaw";
  return {
    ...state, // copy state
    houses: {
      ...state.houses, // copy houses
      [key]: {  // update one specific house (using Computed Property syntax)
        ...state.houses[key],  // copy that specific house's properties
        points: state.houses[key].points + 3   // update its `points` property
      }
    }
  }

By using the spread operator you can update only the new state leaving everything else intact.

Example taken from this amazing article, you can find almost every possible option with great examples.

Like timber said - "Java 8 Collection has a nice method called removeIf that makes things easier and safer"

Here is the code that solve your problem:

set.removeIf((Integer element) -> {
    return (element % 2 == 0);
});

Now your set contains only odd values.

Dial

*#*#2846579#*#*

and you will see a hidden menu. Go to the Project Menu > Background Setting > Log setting and define the log availability (log switch) and level (log level setting).

Please note this may apply to Huawei phones only as is stated for an Ideos X3 (here) and is tested at a Honor U8860.

Some other possibilities:

if (in_array($value, range($min, $max), true)) {
    echo "You can be sure that $min <= $value <= $max";
}

Or:

if ($value === min(max($value, $min), $max)) {
    echo "You can be sure that $min <= $value <= $max";
}

Actually this is what is use to cast a value which is out of the range to the closest end of it.

$value = min(max($value, $min), $max);

Example

/**
 * This is un-sanitized user input.
 */
$posts_per_page = 999;

/**
 * Sanitize $posts_per_page.
 */
$posts_per_page = min(max($posts_per_page, 5), 30);

/**
 * Use.
 */
var_dump($posts_per_page); // Output: int(30)

If you type this text in your bat file:

start /min blah.exe

It will immediately minimize as soon as it opens the program. You will only see a brief flash of it and it will disappear.

I add this only so you can see a quick way to write it so that you can check what will be updated before doing the update.

UPDATE Table 
SET  Table.col1 = other_table.col1,
     Table.col2 = other_table.col2 
--select Table.col1, other_table.col,Table.col2,other_table.col2, *   
FROM     Table 
INNER JOIN     other_table 
    ON     Table.id = other_table.id 

If your source "file" is split up among multiple files (maybe as the result of map-reduce) that live in the same directory tree, you can copy that to a local file with:

hadoop fs -getmerge /hdfs/source/dir_root/ local/destination

If you close the main Activity using Activity.finish(), I think it will close all the activities. MAybe you can override the default function, and implement it in a static way, I'm not sure

This code work for me:

    BufferedImage image = null;
    try {
        URL file = getClass().getResource("water.bmp");
        image = ImageIO.read(file);
    } catch (IOException ioex) {
        System.err.println("load error: " + ioex.getMessage());
    }
    ImageIcon icon = new ImageIcon(image);
    JButton quitButton = new JButton(icon);

Use LIMIT with two parameters. For example, to return results 11-60 (where result 1 is the first row), use:

SELECT * FROM foo LIMIT 10, 50

For a solution to return all results, see Thomas' answer.

You can use RawGit:
https://rawgit.com/necolas/css3-social-signin-buttons/master/index.html

It works better (at the time of this writing) than http://htmlpreview.github.com/, serving files with proper Content-Type headers. Additionally, it also provides CDN URL for use in production.

Try to load your scripts in Head section. Moreover, it will be better if you define your scripts under some call like: document.ready, if you defined these scripts in body section

Decode to Unicode, encode the results to UTF8.

apple.decode('latin1').encode('utf8')

It's caused by n % x where x = 0 in the first loop iteration. You can't calculate a modulus with respect to 0.

Here's the YUI version if anyone's interested:

http://developer.yahoo.com/yui/docs/YAHOO.util.Number.html

var str = YAHOO.util.Number.format(12345, { thousandsSeparator: ',' } );

My solution was subtle and I didn't see it listed already.

I was using reactive forms in an Angular Materials Dialog component that wasn't declared in app.module.ts. The main component was declared in app.module.ts and would open the dialog component but the dialog component was not explicitly declared in app.module.ts.

I didn't have any problems using the dialog component normally except that the form threw this error whenever I opened the dialog.

Can't bind to 'formGroup' since it isn't a known property of 'form'.

You can also get an updated version of the Eclipse's ADT plugin (based on an unreleased 24.2.0 version) that I managed to patch and compile at https://github.com/khaledev/ADT.

Say you have commit id 2 after commit 1 you would be able to run:

git diff 2 1 > mypatch.diff

where 2 and 1 are SHA hashes.

You could try using touch-scroll, a jQuery plugin that mimics scrolling with fixed elements on mobile Safari: https://github.com/neave/touch-scroll

View an example with your iOS device at http://neave.github.com/touch-scroll/

Or an alternative is iScroll: http://cubiq.org/iscroll

Okay, I don't foresee any more answers on this one, so what I ended up going with for now is just a solution for rectangular images. I've used the following NinePatch:



along with the appropriate padding in XML:

<ImageView
        android:id="@+id/image_test"
        android:background="@drawable/drop_shadow"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:paddingLeft="6px"
        android:paddingTop="4px"
        android:paddingRight="8px"
        android:paddingBottom="9px"
        android:src="@drawable/pic1"
        />

to get a fairly good result:



Not ideal, but it'll do.

I'm not sure if I understand your question properly, but it shouldn't matter if this div is a child of some other div. You can simply get text from all divs with class bgHeaderH2 by using following code:

$(".bgHeaderH2").text();

If you need to download a folder via a Linux command try this out:

I found a way to make a textarea with all this working at the same time:

• With horizontal scrollbar
• Supporting multiline text
• Text not wrapping

It works well on:

• Chrome 15.0.874.120
• Firefox 7.0.1
• Opera 11.52 (1100)
• Safari 5.1 (7534.50)
• IE 8.0.6001.18702

Let me explain how i get to that: I was using Chrome inspector integrated tool and I saw values on CSS styles, so I try these values, instead of normal ones... trial & errors till I got it reduced to minimum and here it is for anyone that wants it.

In the CSS section I used just this for Chrome, Firefox, Opera and Safari:

textarea {
  white-space:nowrap;
  overflow:scroll;
}

In the CSS section I used just this for IE:

textarea {
  overflow:scroll;
}

It was a bit tricky, but there is the CSS.

An (x)HTML tag like this:

<textarea id="myTextarea" rows="10" cols="15"></textarea>

And at the end of the <head> section a JavaScript like this:

 window.onload=function(){
   document.getElementById("myTextarea").wrap='off';
 }

The JavaScript is for making the W3C validator passing XHTML 1.1 Strict, since the wrap attribute is not official and thus cannot be an (x)HTML tag directly, but most browsers handle it, so after loading the page it sets that attribute.

Hope this can be tested on more browsers and versions and help someone to improve it and makes it fully cross-browser for all versions.

Handy Backup automatically makes dump files from MS SQL Server, including MSSQL 2005/2008. These dumps are table-level binary files, containing exact copies of the particular database content.

To make a simple dump with Handy Backup, please follow the next instruction:

1. Install Handy Backup and create a new backup task.
2. Select “MSSQL” on a Step 2 as a data source. On a new window, mark a database to back up.
3. Select among different destinations where you will store your backups.
4. On a Step 4, select the “Full” backup option. Set up a time stamp if you need it.
5. Skip a Step 5 unless you have a need to compress or encrypt a resulting dump file.
6. On a Step 6, set up a schedule for a task to create dumps periodically (else run a task manually).
7. Again, skip a Step 7, and give your task a name on a Step 8. You are finished the task!

Now run your new task by clicking on an icon before its name, or wait for scheduled time. Handy Backup will automatically create a dump for your database. Then open your backup destination. You will find a folder (or a couple of folders) with your MS SQL backups. Any such folder will contains a table-level dump file, consisting of some binary tables and settings compressed into a single ZIP.

Other Databases

Handy Backup can save dumps for MySQL, MariaDB, PostgreSQL, Oracle, IBM DB2, Lotus Notes and any generic SQL database having an ODBC driver. Some of these databases require additional steps to establish connections between the DBMS and Handy Backup.

The tools described above often dump SQL databases as table-level SQL command sequence, making these files ready for any manual modifications you need.

Thanks to Devin, I figured out the solution for my SLIM application with multi domain access.

In htaccess:

SetEnvIf Origin "http(s)?://(www\.)?(allowed.domain.one|allowed.domain.two)$" AccessControlAllowOrigin=$0$1
Header set Access-Control-Allow-Origin %{AccessControlAllowOrigin}e env=AccessControlAllowOrigin
Header set Access-Control-Allow-Credentials true

in index.php

// Access-Control headers are received during OPTIONS requests
if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {

    if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_METHOD']))
        header("Access-Control-Allow-Methods: GET, POST, PUT, DELETE, OPTIONS");         

    if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']))
        header("Access-Control-Allow-Headers: {$_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']}");
}
// instead of mapping:
$app->options('/(:x+)', function() use ($app) {
    //...return correct headers...
    $app->response->setStatus(200);
});

List<cTag> week = new List<cTag>();
week.Sort((x, y) => 
    DateTime.ParseExact(x.date, "dd.MM.yyyy", CultureInfo.InvariantCulture).CompareTo(
    DateTime.ParseExact(y.date, "dd.MM.yyyy", CultureInfo.InvariantCulture))
);

To see a list of HTTP request headers, you can use :

console.log(JSON.stringify(req.headers));

to return a list in JSON format.

{
"host":"localhost:8081",
"connection":"keep-alive",
"cache-control":"max-age=0",
"accept":"text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8",
"upgrade-insecure-requests":"1",
"user-agent":"Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2403.107 Safari/537.36",
"accept-encoding":"gzip, deflate, sdch",
"accept-language":"en-US,en;q=0.8,et;q=0.6"
}

This was the solution for me:

-- Check how it is now
select * from patient
select * from patient_address

-- Alter your DB
alter table patient_address nocheck constraint FK__patient_a__id_no__27C3E46E
update patient 
set id_no='7008255601088'
where id_no='8008255601088'

alter table patient_address nocheck constraint FK__patient_a__id_no__27C3E46E
update patient_address 
set id_no='7008255601088'
where id_no='8008255601088'

-- Check how it is now
select * from patient
select * from patient_address

Some Android phones contain Busybox. Was hard to find.

To see if busybox was around:

ls -lR / | grep busybox

If you know it's around. You need some read/write space. Try you flash drive, /sdcard

cd /sdcard
ls -lR / >lsoutput.txt

upload to your computer. Upload the file. Get some text editor. Search for busybox. Will see what directory the file was found in.

busybox find /sdcard -iname 'python*'

to make busybox easier to access, you could:

cd /sdcard
ln -s /where/ever/busybox/is  busybox
/sdcard/busybox find /sdcard -iname 'python*'

Or any other place you want. R

You mean two classes? "Chain" the selectors (no spaces between them):

.class1.class2 {
    /* style here */
}

This selects all elements with class1 that also have class2.

In your case:

li.left.ui-class-selector {

}

Official documentation : CSS2 class selectors.

As akamike points out a problem with this method in Internet Explorer 6 you might want to read this: Use double classes in IE6 CSS?

If you want to download an image from https:

$output_filename = 'output.png';
$host = "https://.../source.png"; // <-- Source image url (FIX THIS)
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $host);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_AUTOREFERER, false);
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); // <-- don't forget this
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); // <-- and this
$result = curl_exec($ch);
curl_close($ch);
$fp = fopen($output_filename, 'wb');
fwrite($fp, $result);
fclose($fp);

much simpler:

$("selector for element").get(0).scrollIntoView();

if more than one item returns in the selector, the get(0) will get only the first item.

Use the doubleNumber.intValue(); method.

There are different clipboards in Linux; the X server has one, the window manager might have another one, etc. There is no standard device.

Oh, yes, on CLI, the screen program has its own clipboard as well, as do some other applications like Emacs and vi.

In X, you can use xclip.

Many people will suggest you use MERGE, but I caution you against it. By default, it doesn't protect you from concurrency and race conditions any more than multiple statements, but it does introduce other dangers:

http://www.mssqltips.com/sqlservertip/3074/use-caution-with-sql-servers-merge-statement/

Even with this "simpler" syntax available, I still prefer this approach (error handling omitted for brevity):

SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
BEGIN TRANSACTION;
UPDATE dbo.table SET ... WHERE PK = @PK;
IF @@ROWCOUNT = 0
BEGIN
  INSERT dbo.table(PK, ...) SELECT @PK, ...;
END
COMMIT TRANSACTION;

A lot of folks will suggest this way:

SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
BEGIN TRANSACTION;
IF EXISTS (SELECT 1 FROM dbo.table WHERE PK = @PK)
BEGIN
  UPDATE ...
END
ELSE
BEGIN
  INSERT ...
END
COMMIT TRANSACTION;

But all this accomplishes is ensuring you may need to read the table twice to locate the row(s) to be updated. In the first sample, you will only ever need to locate the row(s) once. (In both cases, if no rows are found from the initial read, an insert occurs.)

Others will suggest this way:

BEGIN TRY
  INSERT ...
END TRY
BEGIN CATCH
  IF ERROR_NUMBER() = 2627
    UPDATE ...
END CATCH

However, this is problematic if for no other reason than letting SQL Server catch exceptions that you could have prevented in the first place is much more expensive, except in the rare scenario where almost every insert fails. I prove as much here:

• http://www.mssqltips.com/sqlservertip/2632/checking-for-potential-constraint-violations-before-entering-sql-server-try-and-catch-logic/
• http://www.sqlperformance.com/2012/08/t-sql-queries/error-handling

Not sure what you think you gain by having a single statement; I don't think you gain anything. MERGE is a single statement but it still has to really perform multiple operations anyway - even though it makes you think it doesn't.

This is another option, using jQuery and getting only tbody rows (with the data) and desconsidering thead/tfoot.

$("#tableId > tbody > tr").length

console.log($("#myTableId > tbody > tr").length);

I had the same problem when trying to run a PowerShell script that only looked at a remote server to read the size of a hard disk.

I turned off the Firewall (Domain networks, Private networks, and Guest or public network) on the remote server and the script worked.

I then turned the Firewall for Domain networks back on, and it worked.

I then turned the Firewall for Private network back on, and it also worked.

I then turned the Firewall for Guest or public networks, and it also worked.

def word_replace(filename,old,new):
    c=0
    with open(filename,'r+',encoding ='utf-8') as f:
        a=f.read()
        b=a.split()
        for i in range(0,len(b)):
            if b[i]==old:
                c=c+1
        old=old.center(len(old)+2)
        new=new.center(len(new)+2)
        d=a.replace(old,new,c)
        f.truncate(0)
        f.seek(0)
        f.write(d)
    print('All words have been replaced!!!')

You can't call free on the pointers returned from strsep. Those are not individually allocated strings, but just pointers into the string s that you've already allocated. When you're done with s altogether, you should free it, but you do not have to do that with the return values of strsep.

All the previous answers only provide a hard-coded location of where the first column ends and the second column starts. I would have expected that this is not required or even not wanted.

Recent CSS versions know about an attribute called columns which makes column based layouts super easy. For older browsers you need to include -moz-columns and -webkit-columns, too.

Here's a very simple example which creates up to three columns if each of them has at least 200 pixes width, otherwise less columns are used:

<html>
  <head>
    <title>CSS based columns</title>
  </head>
  <body>
    <h1>CSS based columns</h1>
    <ul style="columns: 3 200px; -moz-columns: 3 200px; -webkit-columns: 3 200px;">
      <li>Item one</li>
      <li>Item two</li>
      <li>Item three</li>
      <li>Item four</li>
      <li>Item five</li>
      <li>Item six</li>
      <li>Item eight</li>
      <li>Item nine</li>
      <li>Item ten</li>
      <li>Item eleven</li>
      <li>Item twelve</li>
      <li>Item thirteen</li>
    </ul>
  </body>
</html>

According to Collections Framework Overview you have two balanced tree implementations:

• TreeSet
• TreeMap

str = str.replace(/[^\w\s]|_/g, "")
         .replace(/\s+/g, " ");

Removes everything except alphanumeric characters and whitespace, then collapses multiple adjacent characters to single spaces.

Detailed explanation:

1. \w is any digit, letter, or underscore.
2. \s is any whitespace.
3. [^\w\s] is anything that's not a digit, letter, whitespace, or underscore.
4. [^\w\s]|_ is the same as #3 except with the underscores added back in.

I think this means that

• You are using JDK9 or later
• Your project uses maven-compiler-plugin with an old version which defaults to Java 5.

You have three options to solve this

1. Downgrade to JDK7 or JDK8 (meh)

2. Use maven-compiler-plugin version or later, because

   NOTE: Since 3.8.0 the default value has changed from 1.5 to 1.6 See https://maven.apache.org/plugins/maven-compiler-plugin/compile-mojo.html#target

   <plugin>
       <groupId>org.apache.maven.plugins</groupId>
       <artifactId>maven-compiler-plugin</artifactId>
       <version>3.8.0</version>
   </plugin>
   

3. Indicate to the maven-compiler-plugin to use source level 6 and target 6 (or later).

   Best practice recommended by https://maven.apache.org/plugins/maven-compiler-plugin/

   Also note that at present the default source setting is 1.6 and the default target setting is 1.6, independently of the JDK you run Maven with. You are highly encouraged to change these defaults by setting source and target as described in Setting the -source and -target of the Java Compiler.

   <plugin>
       <groupId>org.apache.maven.plugins</groupId>
       <artifactId>maven-compiler-plugin</artifactId>
       <configuration>
           <source>1.6</source>
           <target>1.6</target>
       </configuration>
   </plugin>
   

   or use

   <properties>
     <maven.compiler.source>1.6</maven.compiler.source>
     <maven.compiler.target>1.6</maven.compiler.target>
   </properties>
   

The System.Uri constructor has the ability to parse full file paths and turn them into URI style paths. So you can just do the following:

var uri = new System.Uri("c:\\foo");
var converted = uri.AbsoluteUri;

I had 2 model properties like this

public int LinkId {get;set;}
public int LinkID {get;set;}

it is strange that it threw this error for these 2 haha..

This is more advice than a specific answer, but my suggestion is to convert dates to date variables immediately, rather than keeping them as strings. This way you can use date (and time) functions on them, rather than trying to use very troublesome workarounds.

As pointed out, the lubridate package has nice extraction functions.

For some projects, I have found that piecing dates out from the start is helpful: create year, month, day (of month) and day (of week) variables to start with. This can simplify summaries, tables and graphs, because the extraction code is separate from the summary/table/graph code, and because if you need to change it, you don't have to roll out those changes in multiple spots.

Use Json class instead of Content as shown following:

    //  When I want to return an error:
    if (!isFileSupported)
    {
        Response.StatusCode = (int) HttpStatusCode.BadRequest;
        return Json("The attached file is not supported", MediaTypeNames.Text.Plain);
    }
    else
    {
        //  When I want to return sucess:
        Response.StatusCode = (int)HttpStatusCode.OK; 
        return Json("Message sent!", MediaTypeNames.Text.Plain);
    }

Also set contentType:

contentType: 'application/json; charset=utf-8',

In my case I wrote like this:

python manage.py makemigrations --empty yourappname

python manage.py migrate yourappname

or:

Django keeps track of all the applied migrations in django_migrations table. So just delete all the rows in the django_migrations table that are related to you app like:

DELETE FROM django_migrations WHERE app='your-app-name'

and then do:

python manage.py makemigrations python manage.py migrate

Almost always List is preferred over ArrayList because, for instance, List can be translated into a LinkedList without affecting the rest of the codebase.

If one used ArrayList instead of List, it's hard to change the ArrayList implementation into a LinkedList one because ArrayList specific methods have been used in the codebase that would also require restructuring.

You can read about the List implementations here.

You may start with an ArrayList, but soon after discover that another implementation is the more appropriate choice.

Use System.Math.Round to rounds a decimal value to a specified number of fractional digits.

var pay = 200 + bonus;
pay = System.Math.Round(pay, 2);
Console.WriteLine(pay);

For elements with dynamic width it's possible to use transform: translateX(-100%); to counter the horizontal percentage value. This leads to two possible solutions:

1. Option: moving the element in the entire viewport:

Transition from:

transform: translateX(0);

to

transform: translateX(calc(100vw - 100%));

#viewportPendulum {_x000D_
  position: fixed;_x000D_
  left: 0;_x000D_
  top: 0;_x000D_
  animation: 2s ease-in-out infinite alternate swingViewport;_x000D_
  /* just for styling purposes */_x000D_
  background: #c70039;_x000D_
  padding: 1rem;_x000D_
  color: #fff;_x000D_
  font-family: sans-serif;_x000D_
}_x000D_
_x000D_
@keyframes swingViewport {_x000D_
  from {_x000D_
    transform: translateX(0);_x000D_
  }_x000D_
  to {_x000D_
    transform: translateX(calc(100vw - 100%));_x000D_
  }_x000D_
}

<div id="viewportPendulum">Viewport</div>

2. Option: moving the element in the parent container:

Transition from:

transform: translateX(0);
left: 0;

to

left: 100%;
transform: translateX(-100%);

#parentPendulum {_x000D_
  position: relative;_x000D_
  display: inline-block;_x000D_
  animation: 2s ease-in-out infinite alternate swingParent;_x000D_

Note: This approach can easily be extended to work for vertical positioning. Visit example here.

Since this is a pretty old question, and this method hasn't been added (aside from the system() call function) I guess it would be useful to include creating the shell script with the C binary itself. The shell code will be housed inside the file.c source file. Here is an example of code:

#include <stdio.h>
#include <stdlib.h>

#define SHELLSCRIPT "\
#/bin/bash \n\
echo -e \"\" \n\
echo -e \"This is a test shell script inside C code!!\" \n\
read -p \"press <enter> to continue\" \n\
clear\
"

int main() {

system(SHELLSCRIPT);
return 0;
}

Basically, in a nutshell (pun intended), we are defining the script name, fleshing out the script, enclosing them in double quotes (while inserting proper escapes to ignore double quotes in the shell code), and then calling that script's name, which in this example is SHELLSCRIPT using the system() function in main().

The only thing that worked for me was modifying the call to suptitle:

fig.suptitle("title", y=.995)
