For a backward search you should use the following:

for (ListIterator<SomeClass> iterator = list.listIterator(list.size()); iterator.hasPrevious();) {
    SomeClass item = iterator.previous();
    ...
    item.remove(); // For instance.
}

If you want to know a position, use iterator.previousIndex(). It also helps to write an inner loop that compares two positions in the list (iterators are not equal).

Try adding a BindingResult parameter to methods annotated with @RequestMapping which have a @ModelAttribute annotated parameters. After each @ModelAttribute parameter, Spring looks for a BindingResult in the next parameter position (order is important).

So try changing:

@RequestMapping(method = RequestMethod.POST)
public String loadCharts(HttpServletRequest request, ModelMap model, @ModelAttribute("sideForm") Chart chart) 
...

To:

@RequestMapping(method = RequestMethod.POST)
public String loadCharts(@ModelAttribute("sideForm") Chart chart, BindingResult bindingResult, HttpServletRequest request, ModelMap model) 
...

no-store should not be necessary in normal situations, and can harm both speed and usability. It is intended for use where the HTTP response contains information so sensitive it should never be written to a disk cache at all, regardless of the negative effects that creates for the user.

How it works:

• Normally, even if a user agent such as a browser determines that a response shouldn't be cached, it may still store it to the disk cache for reasons internal to the user agent. This version may be utilised for features like "view source", "back", "page info", and so on, where the user hasn't necessarily requested the page again, but the browser doesn't consider it a new page view and it would make sense to serve the same version the user is currently viewing.

• Using no-store will prevent that response being stored, but this may impact the browser's ability to give "view source", "back", "page info" and so on without making a new, separate request for the server, which is undesirable. In other words, the user may try viewing the source and if the browser didn't keep it in memory, they'll either be told this isn't possible, or it will cause a new request to the server. Therefore, no-store should only be used when the impeded user experience of these features not working properly or quickly is outweighed by the importance of ensuring content is not stored in the cache.

My current understanding is that it is just for intermediate cache server. Even if "no-cache" is in response, intermediate cache server can still save the content to non-volatile storage.

This is incorrect. Intermediate cache servers compatible with HTTP 1.1 will obey the no-cache and must-revalidate instructions, ensuring that content is not cached. Using these instructions will ensure that the response is not cached by any intermediate cache, and that all subsequent requests are sent back to the origin server.

If the intermediate cache server does not support HTTP 1.1, then you will need to use Pragma: no-cache and hope for the best. Note that if it doesn't support HTTP 1.1 then no-store is irrelevant anyway.

I hope this code will work fine. You can have a try.

// Include this.                
using System.Net.Mail;

string fromAddress = "[email protected]";
string mailPassword = "*****";       // Mail id password from where mail will be sent.
string messageBody = "Write the body of the message here.";


// Create smtp connection.
SmtpClient client = new SmtpClient();
client.Port = 587;//outgoing port for the mail.
client.Host = "smtp.gmail.com";
client.EnableSsl = true;
client.Timeout = 10000;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = false;
client.Credentials = new System.Net.NetworkCredential(fromAddress, mailPassword);


// Fill the mail form.
var send_mail = new MailMessage();

send_mail.IsBodyHtml = true;
//address from where mail will be sent.
send_mail.From = new MailAddress("[email protected]");
//address to which mail will be sent.           
send_mail.To.Add(new MailAddress("[email protected]");
//subject of the mail.
send_mail.Subject = "put any subject here";

send_mail.Body = messageBody;
client.Send(send_mail);

Shouldn't you be providing the credentials for your site, instead of passing the DefaultCredentials?

Something like request.Credentials = new NetworkCredential("UserName", "PassWord");

Also, remove request.UseDefaultCredentials = true; request.PreAuthenticate = true;

A very simple, non fancy, but working solution that I would have to believe is very cross browser:

Create this function

function removeAddClasses(classList,removeCollection,addCollection){_x000D_
    for (var i=0;i<removeCollection.length;i++){ _x000D_
        classList.remove(removeCollection[i]); _x000D_
    }_x000D_
    for (var i=0;i<addCollection.length;i++){ _x000D_
        classList.add(addCollection[i]); _x000D_
    }_x000D_
}

Call it like this: removeAddClasses(node.classList,arrayToRemove,arrayToAdd);

...where arrayToRemove is an array of class names to remove: ['myClass1','myClass2'] etcetera

...and arrayToAdd is an array of class names to add: ['myClass3','myClass4'] etcetera

You can use two elements, one inside the other, and give the outer one overflow: hidden and a width equal to the inner element together with a bottom padding so that the shadow on all the other sides are "cut off"

#outer {
    width: 100px;
    overflow: hidden;
    padding-bottom: 10px;
}

#outer > div {
    width: 100px;
    height: 100px;
    background: orange;

    -moz-box-shadow: 0 4px 4px rgba(0, 0, 0, 0.4);
    -webkit-box-shadow: 0 4px 4px rgba(0, 0, 0, 0.4);
    box-shadow: 0 4px 4px rgba(0, 0, 0, 0.4);
}

Alternatively, float the outer element to cause it to shrink to the size of the inner element. See: http://jsfiddle.net/QJPd5/1/

To whoever it might concern, here's my version that checks for Office 95-2019 & O365, both MSI based and ClickAndRun are supported, on both 32 and 64 bit systems (falls back to 32 bits when 64 bit version is not installed).

Remarks

• Didn't test with office < 2010 though
• Python typing is different between the registry functions and the office functions since I wrote the registry ones before finding out that pypy / python2 does not like typing... On those python interpreters you might just remove typing completly
• Any improvements are highly welcome

I had the same problem as you do and I could solve it by following @CarlosRojas instructions with a little difference. Instead of create a new firewall rule I edited the default-allow-internal one to accept traffic from anywhere since creating new rules didn't make any difference.

A good example is Javascript. You want this to be at the bottom of the page that is rendered in the browser because this is best practice.

How would you do this from a View based on a Layout/Masterpage where you can only access the middle of the page?

You do this by declaring a Scripts section at the bottom of the Layout page. Then you can add content, in this case Javascript includes (I hope!), from your View page to the bottom of your layout page.

You can use a Union.

This will return the results of the queries in separate rows.

First you must make sure that both queries return identical columns.

Then you can do :

SELECT tableA.Id, tableA.Name, [tableB].Username AS Owner, [tableB].ImageUrl, [tableB].CompanyImageUrl, COUNT(tableD.UserId) AS Number
FROM tableD 
RIGHT OUTER JOIN [tableB] 
INNER JOIN tableA ON [tableB].Id = tableA.Owner ON tableD.tableAId = tableA.Id 
GROUP BY tableA.Name, [tableB].Username, [tableB].ImageUrl, [tableB].CompanyImageUrl

UNION

SELECT tableA.Id, tableA.Name,  '' AS Owner, '' AS ImageUrl, '' AS CompanyImageUrl, COUNT([tableC].Id) AS Number
FROM 
[tableC] 
RIGHT OUTER JOIN tableA ON [tableC].tableAId = tableA.Id GROUP BY tableA.Id, tableA.Name

As has been mentioned, both queries return quite different data. You would probably only want to do this if both queries return data that could be considered similar.

SO

You can use a Join

If there is some data that is shared between the two queries. This will put the results of both queries into a single row joined by the id, which is probably more what you want to be doing here...

You could do :

SELECT tableA.Id, tableA.Name, [tableB].Username AS Owner, [tableB].ImageUrl, [tableB].CompanyImageUrl, COUNT(tableD.UserId) AS NumberOfUsers, query2.NumberOfPlans
FROM tableD 
RIGHT OUTER JOIN [tableB] 
INNER JOIN tableA ON [tableB].Id = tableA.Owner ON tableD.tableAId = tableA.Id 


INNER JOIN 
  (SELECT tableA.Id, COUNT([tableC].Id) AS NumberOfPlans 
   FROM [tableC] 
   RIGHT OUTER JOIN tableA ON [tableC].tableAId = tableA.Id 
   GROUP BY tableA.Id, tableA.Name) AS query2 
ON query2.Id = tableA.Id

GROUP BY tableA.Name, [tableB].Username, [tableB].ImageUrl, [tableB].CompanyImageUrl

You should accept Mike Gossland's answer, but it can be improved a little. Try this in Git Bash:

 ls -1F /bin | grep '\*$' | grep -v '\.dll\*$' | sed 's/\*$\|\.exe//g'

Explanation:

List on 1 line, decorated with trailing * for executables, all files in bin. Keep only those with the trailing *s, but NOT ending with .dll*, then replace all ending asterisks or ".exe" with nothing.

This gives you a clean list of all the GitBash commands.

You may debug using two ways:

1. Press CTRL+U to view page Source . Press CTRL+F to find "mystyles.css" in source . click on mystyles.css link and check if it is not showing "404 not found".

2. You can INSPECT ELEMENT IN FIRBUG and set path to Image ,Set Image height and width because sometimes image doesnt show up.

Hope this may works !!.

I like doing the maths in milliseconds. So use Date.now()

var newDate = Date.now() + -5*24*3600*1000; // date 5 days ago in milliseconds

and if you like it formatted

new Date(newDate).toString(); // or .toUTCString or .toISOString ...

NOTE: Date.now() doesn't work in older browsers (eg IE8 I think). Polyfill here.

UPDATE June 2015

@socketpair pointed out my sloppiness. As s/he says "Some day in year have 23 hours, and some 25 due to timezone rules".

To expand on that, the answer above will have daylightsaving inaccuracies in the case where you want to calculate the LOCAL day 5 days ago in a timezone with daylightsaving changes and you

• assume (wrongly) that Date.now() gives you the current LOCAL now time, or
• use .toString() which returns the local date and therefore is incompatible with the Date.now() base date in UTC.

However, it works if you're doing your math all in UTC, eg

A. You want the UTC date 5 days ago from NOW (UTC)

var newDate = Date.now() + -5*24*3600*1000; // date 5 days ago in milliseconds UTC
new Date(newDate).toUTCString(); // or .toISOString(), BUT NOT toString

B. You start with a UTC base date other than "now", using Date.UTC()

newDate = new Date(Date.UTC(2015, 3, 1)).getTime() + -5*24*3600000;
new Date(newDate).toUTCString(); // or .toISOString BUT NOT toString

to accomplish what you want, you must getPaths from the polygon. Paths will be an array of LatLng points. you get the elements of the array and split the LatLng pairs with the methods .lat and .lng in the function below, i have a redundant array corresponding to a polyline that marks the perimeter around the polygon.

saving is another story. you can then opt for many methods. you may save your list of points as a csv formatted string and export that to a file (easiest solution, by far). i highly recommend GPS TXT formats, like the ones (there are 2) readable by GPS TRACKMAKER (great free version software). if you are competent to save them to a database, that is a great solution (i do both, for redundancy).

attention, the line that ends with ",1" (as opposed to ",0") starts a new polygon (this format allows you to save multiple polygons in the same file). i find TXT more human readable than the XML based formats GPX and KML.

If you get your adb from Android Studio (which most will nowadays since Android is deprecated on Eclipse), your adb program will most likely be located here:

%USERPROFILE%\AppData\Local\Android\sdk\platform-tools

Where %USERPROFILE% represents something like C:\Users\yourName.

If you go into your computer's environmental variables and add %USERPROFILE%\AppData\Local\Android\sdk\platform-tools to the PATH (just copy-paste that line, even with the % --- it will work fine, at least on Windows, you don't need to hardcode your username) then it should work now. Open a new command prompt and type adb to check.

The root of this exception in my case was that at some point in code the following was being called:

ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;

This is really bad. Not only is it instructing .NET to use an insecure protocol, but this impacts every new WebClient (and similar) request made afterward within your appdomain. (Note that incoming web requests are unaffected in your ASP.NET app, but new WebClient requests, such as to talk to an external web service, are).

In my case, it was not actually needed, so I could just delete the statement and all my other web requests started working fine again. Based on my reading elsewhere, I learned a few things:

• This is a global setting in your appdomain, and if you have concurrent activity, you can't reliably set it to one value, do your action, and then set it back. Another action may take place during that small window and be impacted.
• The correct setting is to leave it default. This allows .NET to continue to use whatever is the most secure default value as time goes on and you upgrade frameworks. Setting it to TLS12 (which is the most secure as of this writing) will work now but in 5 years may start causing mysterious problems.
• If you really need to set a value, you should consider doing it in a separate specialized application or appdomain and find a way to talk between it and your main pool. Because it's a single global value, trying to manage it within a busy app pool will only lead to trouble. This answer: https://stackoverflow.com/a/26754917/7656 provides a possible solution by way of a custom proxy. (Note I have not personally implemented it.)

You need to implement the equals() method in your MyClass.

The reason that == didn't work is this is checking that they refer to the same instance. Since you did new for each, each one is a different instance.

The reason that equals() didn't work is because you didn't implement it yourself yet. I believe it's default behavior is the same thing as ==.

Note that you should also implement hashcode() if you're going to implement equals() because a lot of java.util Collections expect that.

I know the OP tagged the question with javascript but in my case I was looking exactly the same thing but from a Java backend (with Camel).

An interesting thing that can also be useful if you are using an integration framework like Camel, jsonPath is also supported by a specific Camel Component since Camel 2.13.

Example from the Camel doc above:

from("queue:books.new")
  .choice()
    .when().jsonpath("$.store.book[?(@.price < 10)]")
      .to("jms:queue:book.cheap")
    .when().jsonpath("$.store.book[?(@.price < 30)]")
      .to("jms:queue:book.average")
    .otherwise()
      .to("jms:queue:book.expensive")

which is quite straightforward to use.

You need to put your code into ngOnInit and use the this keyword:

ngOnInit() {
  this.booksByStoreID = this.books.filter(
          book => book.store_id === this.store.id);
}

You need ngOnInit because the input store wouldn't be set into the constructor:

ngOnInit is called right after the directive's data-bound properties have been checked for the first time, and before any of its children have been checked. It is invoked only once when the directive is instantiated.

(https://angular.io/docs/ts/latest/api/core/index/OnInit-interface.html)

In your code, the books filtering is directly defined into the class content...

If you use the latest spring-boot 2.1.6.RELEASE with a simple @RestController annotation then you do not need to do anything, just add your index.html file under the resources/static folder:

          +-- resources
              +-- static
                  +-- index.html

Why the base class' default constructor is called? Turns out it's not always be the case. Any constructor of the base class (with different signatures) can be invoked from the derived class' constructor. In your case, the default constructor is called because it has no parameters so it's default.

When a derived class is created, the order the constructors are called is always Base -> Derived in the hierarchy. If we have:

class A {..}
class B : A {...}
class C : B {...}
C c;

When c is create, the constructor for A is invoked first, and then the constructor for B, and then the constructor for C.

To guarantee that order, when a derived class' constructor is called, it always invokes the base class' constructor before the derived class' constructor can do anything else. For that reason, the programmer can manually invoke a base class' constructor in the only initialisation list of the derived class' constructor, with corresponding parameters. For instance, in the following code, Derived's default constructor will invoke Base's constructor Base::Base(int i) instead of the default constructor.

Derived() : Base(5)
{      
}

If there's no such constructor invoked in the initialisation list of the derived class' constructor, then the program assumes a base class' constructor with no parameters. That's the reason why a constructor with no parameters (i.e. the default constructor) is invoked.

I know this is absolutely not the right way to do it, yet it've helped me a few times in the past to get the approx object file size:

Write your object/response to the console or a new tab, copy the results to a new notepad file, save it, and check the file size. The notepad file itself is just a few bytes, so you'll get a fairly accurate object file size.

How about something like

CREATE TABLE testRequest (
        wardNo nchar(5),
        BHTNo nchar(5),
        testID nchar(5),
        reqDateTime datetime,
        PRIMARY KEY (wardNo, BHTNo, testID)
);

Since you need the tracks to close the streaming, and you need the stream boject to get to the tracks, the code I have used with the help of the Muaz Khan's answer above is as follows:

if (navigator.getUserMedia) {
    navigator.getUserMedia(constraints, function (stream) {
        videoEl.src = stream;
        videoEl.play();
        document.getElementById('close').addEventListener('click', function () {
            stopStream(stream);
        });
    }, errBack);

function stopStream(stream) {
console.log('stop called');
stream.getVideoTracks().forEach(function (track) {
    track.stop();
});

Of course this will close all the active video tracks. If you have multiple, you should select accordingly.

If the end of sequence has maximal length of padding (for example, if you want 5 digits and command is "seq 1 10000"), than you can use "-w" flag for seq - it adds padding itself.

step 1- Mount your Google Drive to Collaboratory

from google.colab import drive
drive.mount('/content/gdrive')

step 2- Now you will see your Google Drive files in the left pane (file explorer). Right click on the file that you need to import and select çopy path. Then import as usual in pandas, using this copied path.

import pandas as pd
df=pd.read_csv('gdrive/My Drive/data.csv')

Done!

You have to enable null value for your date variable :

 public Nullable<DateTime> MyDate{ get; set; }

You could convert the dataframe to be a single column with stack (this changes the shape from 5x3 to 15x1) and then take the standard deviation:

df.stack().std()         # pandas default degrees of freedom is one

Alternatively, you can use values to convert from a pandas dataframe to a numpy array before taking the standard deviation:

df.values.std(ddof=1)    # numpy default degrees of freedom is zero

Unlike pandas, numpy will give the standard deviation of the entire array by default, so there is no need to reshape before taking the standard deviation.

A couple of additional notes:

• The numpy approach here is a bit faster than the pandas one, which is generally true when you have the option to accomplish the same thing with either numpy or pandas. The speed difference will depend on the size of your data, but numpy was roughly 10x faster when I tested a few different sized dataframes on my laptop (numpy version 1.15.4 and pandas version 0.23.4).

• The numpy and pandas approaches here will not give exactly the same answers, but will be extremely close (identical at several digits of precision). The discrepancy is due to slight differences in implementation behind the scenes that affect how the floating point values get rounded.

You could use a macro, but it’s simpler to use styles. Define a character style that has the desired text color and assign a shortcut key to it, say Alt+R. In order to be able to switch color using just the keyboard, define another character style, say “normal”, that has no special feature—just for use to get normal text after switching to your colored style, and assign another shortcut to it, say Alt+N. Then you would just type text, press Alt+R to switch to colored text, type that text, press Alt+N to resume normal text color, etc.

I guess it might be because it is expecting a single value?

taken from the animate page on jQuery:

Animation Properties and Values

All animated properties should be animated to a single numeric value, except as noted below; most properties that are non-numeric cannot be animated using basic jQuery functionality. (For example, width, height, or left can be animated but background-color cannot be.) Property values are treated as a number of pixels unless otherwise specified. The units em and % can be specified where applicable.

Use Following Method to Update GUI.

     Public Void UpdateUI()
     {
         //Here update your label, button or any string related object.

         Application.Current.Dispatcher.Invoke(DispatcherPriority.Background, new ThreadStart(delegate { }));
     }

Keep it in Mind when you use this method at that time do not Update same object direct from dispatcher thread otherwise you get only that updated string and this method is helpless/useless. If still not working then Comment that line inside method and un-comment commented one both have nearly same effect just different way to access it.

Check out Loom (http://theengine.co) is a new cross platform 2D game engine featuring hot swapping code & assets on devices. This means that you can work in Photoshop on your assets, you can update your code, modify the UI of your app/game and then see the changes on your device(s) while the app is running.

Thinking to the other cross platform game engines I’ve heard of or even played with, the Loom Game Engine is by far the best in my oppinion with lots of great features. Most of the other similar game engines (Corona SDK, MOAI SDK, Gideros Mobile) are Lua based (with an odd syntax, at least for me). The Loom Game Engine uses LoomScripts, a scripting language inspired from ActionScript 3, with a couple of features borrowed from C#. If you ever developed in ActionScript 3, C# or Java, LoomScript will look familiar to you (and I’m more comfortable with this syntax than with Lua’s syntax).

The 1 year license for the Loom Game Engine costs $500, and I think it’s an affordable price for any indie game developer. Couple of weeks ago the offered a 1 year license for free too. After the license expires, you can still use Loom to create and deploy your own games, but you won’t get any further updates. The creators of Loom are very confident and they promised to constantly improve their baby making it worthwile to purchase another license.

Without further ado, here are Loom’s great features:

1. Cross platform (iOS, Android, OS X, Windows, Linux/Ubuntu)

2. Rails-inspired workflow lets you spend your time working with your game (one command to create a new project, and another command to run it)

3. Fast compiler

4. Live code and assets editing

5. Possibility to integrate third party libraries

6. Uses Cocos2DX for rendering

7. XML, JSON support

8. LML (markup language) and CSS for styling UI elements

9. UI library

10. Dependency injection

11. Unit test framework

12. Chipmunk physics

13. Seeing your changes live makes multidevice development easy

14. Small download size

15. Built for teams

You can find more videos about Loom here: http://www.youtube.com/user/LoomEngine?feature=watch

Datatables have a .Select method, which returns a rows array according to the criteria you specify. Something like this:

Dim oRows() As DataRow

oRows = dtCountries.Select("CountryName = '" & userinput & "'")

If oRows.Count = 0 Then
   ' No rows found
Else
   ' At least one row found. Could be more than one
End If

Of course, if userinput contains ' character, it would raise an exception (like if you query the database). You should escape the ' characters (I use a function to do that).

The default generator for Windows seems to be set to NMAKE. Try to use:

cmake -G "MinGW Makefiles"

Or use the GUI, and select MinGW Makefiles when prompted for a generator. Don't forget to cleanup the directory where you tried to run CMake, or delete the cache in the GUI. Otherwise, it will try again with NMAKE.

also if you need to select a sibling with a name rather than the class, you could use the following

var $sibling = $(this).siblings('input[name=bidbutton]');

There can be multiple root causes for this exception. For me, my mockMvc wasn't getting auto-configured. I solved this exception by using @WebMvcTest(MyController.class) at the class level. This annotation will disable full auto-configuration and instead apply only configuration relevant to MVC tests.

An alternative to this is, If you are looking to load your full application configuration and use MockMVC, you should consider @SpringBootTest combined with @AutoConfigureMockMvc rather than @WebMvcTest

Try a list comprehension:

l = [x * 2 for x in l]

This goes through l, multiplying each element by two.

Of course, there's more than one way to do it. If you're into lambda functions and map, you can even do

l = map(lambda x: x * 2, l)

to apply the function lambda x: x * 2 to each element in l. This is equivalent to:

def timesTwo(x):
    return x * 2

l = map(timesTwo, l)

Note that map() returns a map object, not a list, so if you really need a list afterwards you can use the list() function afterwards, for instance:

l = list(map(timesTwo, l))

Thanks to Minyc510 in the comments for this clarification.

I think it is much more simple solution:

window.location = (""+window.location).replace(/#[A-Za-z0-9_]*$/,'')+"#myAnchor"

This method does not reload the website, and sets the focus on the anchors which are needed for screen reader.

You probably don't want to pass the car object as a parameter, try just passing car.id. What do you get when you inspect(params) after clicking "Add to cart"?

One way is to call A's constructor and pass self as an argument, like so:

class B(A):
    def __init__(self):
        A.__init__(self)
        print "hello"

The advantage of this style is that it's very clear. It call A's initialiser. The downside is that it doesn't handle diamond-shaped inheritance very well, since you may end up calling the shared base class's initialiser twice.

Another way is to use super(), as others have shown. For single-inheritance, it does basically the same thing as letting you call the parent's initialiser.

However, super() is quite a bit more complicated under-the-hood and can sometimes be counter-intuitive in multiple inheritance situations. On the plus side, super() can be used to handle diamond-shaped inheritance. If you want to know the nitty-gritty of what super() does, the best explanation I've found for how super() works is here (though I'm not necessarily endorsing that article's opinions).

@Harris's answer is great, I've implemented it as a separate subclass of EditText, which can make it easier to use if your code already adds TextChangedListeners.

Also, I've tweaked it so that, if you already use any Compound Drawables, it leaves them intact.

Code is here, for anyone who needs it:

package com.companyname.your

import android.graphics.drawable.Drawable;
import android.text.Editable;
import android.text.TextWatcher;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.view.View;
import android.widget.EditText;

public class ClearableEditText extends EditText {

    public String defaultValue = "";
    final Drawable imgX = getResources().getDrawable(android.R.drawable.presence_offline ); // X image


    public ClearableEditText(Context context) {
        super(context);

        init();
    }

    public ClearableEditText(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);

        init();
    }

    public ClearableEditText(Context context, AttributeSet attrs) {
        super(context, attrs);

        init();
    }


    void init()  {

        // Set bounds of our X button
        imgX.setBounds(0, 0, imgX.getIntrinsicWidth(), imgX.getIntrinsicHeight());      

        // There may be initial text in the field, so we may need to display the button
        manageClearButton();

        this.setOnTouchListener(new OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {

                ClearableEditText et = ClearableEditText.this;

                // Is there an X showing?
                if (et.getCompoundDrawables()[2] == null) return false;
                // Only do this for up touches
                if (event.getAction() != MotionEvent.ACTION_UP) return false;
                // Is touch on our clear button?
                if (event.getX() > et.getWidth() - et.getPaddingRight() - imgX.getIntrinsicWidth()) {
                    et.setText("");
                    ClearableEditText.this.removeClearButton();
                }
                return false;
            }
        });

        this.addTextChangedListener(new TextWatcher() {
            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {

                ClearableEditText.this.manageClearButton();
            }

            @Override
            public void afterTextChanged(Editable arg0) {
            }

            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {
            }
        });
    }

    void manageClearButton() {
        if (this.getText().toString().equals("") )
            removeClearButton();
        else
            addClearButton();
    }
    void addClearButton() {
        this.setCompoundDrawables(this.getCompoundDrawables()[0], 
                this.getCompoundDrawables()[1],
                imgX,
                this.getCompoundDrawables()[3]);
    }
    void removeClearButton() {
        this.setCompoundDrawables(this.getCompoundDrawables()[0], 
                this.getCompoundDrawables()[1],
                null,
                this.getCompoundDrawables()[3]);
    }

}

In case you want to add the URL parameter in JavaScript, see this answer. As suggested there, you can use the URLSeachParams API in modern browsers as follows:

<script>
function addUrlParameter(name, value) {
  var searchParams = new URLSearchParams(window.location.search)
  searchParams.set(name, value)
  window.location.search = searchParams.toString()
}
</script>

<body>
...
  <a onclick="addUrlParameter('like', 'like')">Like this page</a>
...
</body>

Since node v0.11 you can use the standard util function :

var util = require('util');
util.isFunction('foo');

Visual Studio reads NuGet.Config files from the solution root. Try moving it there instead of placing it in the same folder as the project.

You can also place the file at %appdata%\NuGet\NuGet.Config and it will be used everywhere.

https://docs.microsoft.com/en-us/nuget/schema/nuget-config-file

You can increase body size in nginx configuration file as

sudo nano /etc/nginx/nginx.conf

client_max_body_size 100M;

Restart nginx to apply the changes.

sudo service nginx restart

It is not possible at all. Variable names aren't communicated within Java (and might also be removed due to compiler optimizations).

EDIT (related to comments):

If you step back from the idea of having to use it as function parameters, here's an alternative (which I wouldn't use - see below):

public void printFieldNames(Object obj, Foo... foos) {
    List<Foo> fooList = Arrays.asList(foos);
    for(Field field : obj.getClass().getFields()) {
         if(fooList.contains(field.get()) {
              System.out.println(field.getName());
         }
    }
}

There will be issues if a == b, a == r, or b == r or there are other fields which have the same references.

EDIT now unnecessary since question got clarified

I was looking for getting val by internal field name instead of ID and came from google to this post which help but did not find the solution I need, but I got the solution and here it is:

So this might help somebody looking for selected value with field internal name instead of using long id for SharePoint lists:

var e = $('select[title="IntenalFieldName"] option:selected').text(); 

Your file has Windows line endings, which is confusing Linux.

Remove the spurious CR characters. You can do it with the following command:

In version 3, they changed "export" to "unload". It still functions more or less the same.

Cause you are comparing the first element of the array against itself so It finds that there are duplicates even where there aren't.

I tried to connect sql server in following ways and those worked for me.

To connect using windows authentication

import pyodbc

conn = pyodbc.connect('Driver={SQL Server};Server='+servername+';Trusted_Connection=yes;Database='+databasename+';')
cursor = conn.cursor()
cursor.execute("Select 1 as Data")

To use sql server authentication I used following code.

import pyodbc

conn = pyodbc.connect('Driver={SQL Server};Server='+servername+  ';UID='+userid+';PWD='+password+';Database='+databasename) 
cursor1 = conn.cursor()
cursor1.execute("SELECT 1 AS DATA")

If you a running Jupyter/Ipython notebook and having problems using;

ax = df1.plot()

df2.plot(ax=ax)

Run the command inside of the same cell!! It wont, for some reason, work when they are separated into sequential cells. For me at least.

Not trying to take any credits here, all credit goes to @theazureshadow for his reply, but I personally had to adapt it for a table that has some <th> instead of <td> for it's first row's cells.

I'm just posting the modified version here in case some of you want to use @theazureshadow's solution, but like me, have some <th> in the first <tr>. The class "reportTable" only have to be applied to the table itself.:

table.reportTable {
    border-collapse: separate;
    border-spacing: 0;
}

table.reportTable td {
    border: solid gray 1px;
    border-style: solid none none solid;
    padding: 10px;
}

table.reportTable td:last-child {
    border-right: solid gray 1px;
}

table.reportTable tr:last-child td{
    border-bottom: solid gray 1px;
}

table.reportTable th{
    border: solid gray 1px;
    border-style: solid none none solid;
    padding: 10px;
}

table.reportTable th:last-child{
    border-right: solid gray 1px;
    border-top-right-radius: 10px;
}

table.reportTable th:first-child{
    border-top-left-radius: 10px;
}

table.reportTable tr:last-child td:first-child{
    border-bottom-left-radius: 10px;
}   

table.reportTable tr:last-child td:last-child{
    border-bottom-right-radius: 10px;
}

Feel free to adjust the paddings, radiuses, etc to fit your needs. Hope that helps people!

PHP uses weak typing (which it calls 'type juggling'), which is a bad idea (though that's a conversation for another time). When you try to use a variable in a context that requires a boolean, it will convert whatever your variable is into a boolean, according to some mostly arbitrary rules available here: http://www.php.net/manual/en/language.types.boolean.php#language.types.boolean.casting

git stash apply also works with other refs than stash@{0}. So you can use ordinary tags to get a persistent name. This also has the advantage that you cannot accidentaly git stash drop or git stash pop it.

So you can define an alias pstash (aka "persistent stash") like this:

git config --global alias.pstash '!f(){ git stash && git tag "$1" stash && git stash drop; }; f'

Now you can create a tagged stash:

git pstash x-important-stuff

and show and apply it again as usual:

git stash show x-important-stuff
git stash apply x-important-stuff

For hide keyboard use Keyboard.dismiss() inside TextInput.

I don't think that can be done RELIABLY with built in methods on the native Date object. The toLocaleString method gets close, but if I am remembering correctly, it won't work correctly in IE < 10. If you are able to use a library for this task, MomentJS is a really amazing library; and it makes working with dates and times easy. Otherwise, I think you will have to write a basic function to give you the format that you are after.

function formatDate(date) {
    var year = date.getFullYear(),
        month = date.getMonth() + 1, // months are zero indexed
        day = date.getDate(),
        hour = date.getHours(),
        minute = date.getMinutes(),
        second = date.getSeconds(),
        hourFormatted = hour % 12 || 12, // hour returned in 24 hour format
        minuteFormatted = minute < 10 ? "0" + minute : minute,
        morning = hour < 12 ? "am" : "pm";

    return month + "/" + day + "/" + year + " " + hourFormatted + ":" +
            minuteFormatted + morning;
}

A convinient way is using the package python-dotenv: It reads out a .flaskenv file where you can store environment variables for flask.

• pip install python-dotenv
• create a file .flaskenv in the root directory of your app

Inside the file you specify:

FLASK_APP=application.py
FLASK_RUN_HOST=localhost
FLASK_RUN_PORT=80

After that you just have to run your app with flask run and can access your app at that port.

Please note that FLASK_RUN_HOST defaults to 127.0.0.1 and FLASK_RUN_PORT defaults to 5000.

I'm not sure I understand what you are trying to achieve as we don't have what username() is supposed to return but you might want to try something like that. I would also recommend you don't echo whole page and rather use something like that, it's much easier to read and maintain:

<?php
require_once ( 'username.php' );
if (isset($_POST)) {
  $textfield = $_POST['textfield']; // this will get you what was in the
                                    // textfield if the form was submitted
}
?>

<form name="form1" method="post" action="<?php echo($_SERVER['PHP_SELF']) ?">
  <p>Your username is: <?php echo(username()) ?></p>
  <p>
    <label>
      <input type="text" name="textfield" id="textfield">
    </label>
  </p>
  <p>
    <label>
      <input type="submit" name="button" id="button" value="Submit">
    </label>
  </p>
</form>

This will post the results in the same page. So first time you display the page, only the empty form is shown, if you press on submit, the textfield field will be in the $textfield variable and you can display it again as you want.

I don't know if the username() function was supposed to return you the URL of where you should send the results but that's what you'd want in the action attribute of your form. I've put the result down in a sample paragraph so you see how you can display the result. See the "Your username is..." part.

// Edit:

If you want to send the value without leaving the page, you want to use AJAX. Do a search on jQuery on StackOverflow or on Google.

You would probably want to have your function return the username instead of echo it though. But if you absolutely want to echo it from the function, just call it like that <?php username() ?> in your HTML form.

I think you will need to understand the flow of the client-server process of your pages before going further. Let's say that the sample code above is called form.php.

1. Your form.php is called.
2. The form.php generates the HTML and is sent to the client's browser.
3. The client only sees the resulting HTML form.
4. When the user presses the button, you have two choices: a) let the browser do its usual thing so send the values in the form fields to the page specified in action (in this case, the URL is defined by PHP_SELF which is the current page.php). Or b) use javascript to push this data to a page without refreshing the page, this is commonly called AJAX.
5. A page, in your case, it could be changed to username.php, will then verify against the database if the username exists and then you want to regenerate HTML that contains the values you need, back to step 1.

Just to add to the many different ways this can show up.

If you using safari on iOS and you are connected to the Safari Technology Preview console - you will see the same problem. If you disconnect from the console - the problem will go away.

Of course it makes troubleshooting other issues difficult but it is a 100% repro.

I am trying to figure out what I can change in STP to stop it from doing this but have not found it yet.

It's basically the same mechanism as for a non query command with:

• command.CommandText = the name of the stored procedure
• command.CommandType = CommandType.StoredProcedure
• As many calls to command.Parameters.Add as the number of parameters the sp requires
• command.ExecuteNonQuery

There are plenty of examples out there, the first one returned by Google is this one

There's also a little trap you might fall into, if your SP is a function, your return value parameter must be first in the parameters collection

@Wardenclyffe and @SColvin, you both are trying to save image using the canvas, not by using canvas's context. both you should try to ctx.toDataURL(); Try This:

var canvas1 = document.getElementById("yourCanvasId");  <br>
var ctx = canvas1.getContext("2d");<br>
var img = new Image();<br>
img.src = ctx.toDataURL('image/png');<br>
ctx.drawImage(img,200,150);<br>

Also you may refer to following links:

http://tutorials.jenkov.com/html5-canvas/todataurl.html

http://www.w3.org/TR/2012/WD-html5-author-20120329/the-canvas-element.html#the-canvas-element

Same solution, but just to remind you: You can define the shadow directly in the storyboard.

Ex:

Replace this

 <button type="button" value=" Send" class="btn btn-success" type="submit" id="submit">

with

<button  value=" Send" class="btn btn-success" type="submit" id="submit">

shell_exec - Execute command via shell and return the complete output as a string

exec - Execute an external program.

The difference is that with shell_exec you get output as a return value.

Instead, ASL utilizes a native service running in the background, started via the Android Debug Bridge (ADB) once per device boot.

Gson allows for one of the simplest possible solutions. Compared to similar APIs like Jackson or svenson, Gson by default doesn't even need the unused JSON elements to have bindings available in the Java structure. Specific to the question asked, here's a working solution.

import com.google.gson.Gson;

public class Foo
{
  static String jsonInput = 
    "{" + 
      "\"name\":\"John\"," + 
      "\"age\":\"20\"," + 
      "\"address\":\"some address\"," + 
      "\"someobject\":" +
      "{" + 
        "\"field\":\"value\"" + 
      "}" + 
    "}";

  String age;

  public static void main(String[] args) throws Exception
  {
    Gson gson = new Gson();
    Foo thing = gson.fromJson(jsonInput, Foo.class);
    if (thing.age != null)
    {
      System.out.println("age is " + thing.age);
    }
    else
    {
      System.out.println("age element not present or value is null");
    }
  }
}

1. Open your terminal.
2. Run cd /
3. Run sudo chown -R $(whoami):$(whoami) /var

Note: I tested it using ubuntu os

var part = location.hostname.split('.');
var subdomains = part.shift();
var upperleveldomains = part.join('.');

second-level-domain, you might use

var sleveldomain = parts.slice(-2).join('.');

 var cors = new EnableCorsAttribute("*","*","*");
 config.EnableCors(cors);

 var constraints = new {httpMethod = new HttpMethodConstraint(HttpMethod.Options)};
 config.Routes.IgnoreRoute("OPTIONS", "*pathInfo",constraints);

One classic root cause for this message is:

• when the repo has been initialized (git init lis4368/assignments),
• but no commit has ever been made

Ie, if you don't have added and committed at least once, there won't be a local master branch to push to.

Try first to create a commit:

• either by adding (git add .) then git commit -m "first commit"
  (assuming you have the right files in place to add to the index)
• or by create a first empty commit: git commit --allow-empty -m "Initial empty commit"

And then try git push -u origin master again.

See "Why do I need to explicitly push a new branch?" for more.

# Hide grid lines

Note, you need matplotlib>=1.2 for set_zticks() to work.

Yes It will. Only case it will not is JVM exits or crashes

In addition to Adam Rosenfield's answer, I would like to add that ByteBuffer.array() returns the buffer's underlying byte array, which is not necessarily "trimmed" up to the last character. Extra manipulation will be needed, such as the ones mentioned in this answer; in particular:

byte[] b = new byte[bb.remaining()]
bb.get(b);

I think this is a very useful question with good answer. Just to add my two cents from the MSDN Create a Login page:

A login is a security principal, or an entity that can be authenticated by a secure system. Users need a login to connect to SQL Server. You can create a login based on a Windows principal (such as a domain user or a Windows domain group) or you can create a login that is not based on a Windows principal (such as an SQL Server login).

Note:
To use SQL Server Authentication, the Database Engine must use mixed mode authentication. For more information, see Choose an Authentication Mode.

As a security principal, permissions can be granted to logins. The scope of a login is the whole Database Engine. To connect to a specific database on the instance of SQL Server, a login must be mapped to a database user. Permissions inside the database are granted and denied to the database user, not the login. Permissions that have the scope of the whole instance of SQL Server (for example, the CREATE ENDPOINT permission) can be granted to a login.

it worked for me adding type="module" to the script importing my mjs:

<script type="module">
import * as module from 'https://rawgit.com/abernier/7ce9df53ac9ec00419634ca3f9e3f772/raw/eec68248454e1343e111f464e666afd722a65fe2/mymod.mjs'

console.log(module.default()) // Prints: Hi from the default export!
</script>

This is guaranteed to have nothing to do with the compiler. All compilers do is compile the code that they are given. What you're looking for is a GUI library, which you can write code against using any compiler that you want.

Of course, that being said, your first order of business should be to ditch Turbo C. That compiler is about 20 years old and continuing to use it isn't doing you any favors. You can't write modern GUI applications, as it will only produce 16-bit code. All modern operating systems are 32-bit, and many are now 64-bit. It's also worth noting that 64-bit editions of Windows will not run 16-bit applications natively. You'll need an emulator for that; it's not really going to engender much feeling of accomplishment if you can only write apps that work in a DOS emulator. :-)

Microsoft's Visual Studio Express C++ is available as a free download. It includes the same compiler available in the full version of the suite. The C++ package also compiles pure C code.

And since you're working in Windows, the Windows API is a natural choice. It allows you to write native Windows applications that have access to the full set of GUI controls. You'll find a nice tutorial here on writing WinAPI applications in C. If you choose to go with Visual Studio, it also includes boilerplate code for a blank WinAPI application that will get you up and running quickly.

If you really care about learning to do this, Charles Petzold's Programming Windows is the canonical resource of the subject, and definitely worth a read. The entire Windows API was written in C, and it's entirely possible to write full-featured Windows applications in C. You don't need no stinkin' C++.

That's the way I'd do it, at least. As the other answers suggest, GTK is also an option. But the applications it generates are just downright horrible-looking on Windows.

EDIT: Oh dear... It looks like you're not alone in wanting to write "GUI" applications using an antiquated compiler. A Google search turns up the following library: TurboGUI: A GUI Framework for Turbo C/C++:

If you're another one of those poor people stuck in the hopelessly out-of-date Indian school system and forced to use Turbo C to complete your education, this might be an option. I'm loathe to recommend it, as learning to work around its limitations will be completely useless to you once you graduate, but apparently it's out there for you if you're interested.

This happens because the i propagates up the scope once the function is invoked. You can avoid this issue using a closure.

for (var i = 0; i < 10; i++) {
   var link = document.createElement('a');
   link.setAttribute('href', '#');
   link.innerHTML = i + '';
   link.onclick = (function() {
      var currentI = i;
      return function() { 
          onClickLink(currentI + '');
      }
   })();
   div.appendChild(link);
   div.appendChild(document.createElement('BR'));
}

Or if you want more concise syntax, I suggest you use Nick Craver's solution.

Another way to do this is to define the functions in a groovy class and parse and add the file to the classpath at runtime:

File sourceFile = new File("path_to_file.groovy");
Class groovyClass = new GroovyClassLoader(getClass().getClassLoader()).parseClass(sourceFile);
GroovyObject myObject = (GroovyObject) groovyClass.newInstance();

You can find/debug XPath/CSS locators in the IE as well as in different browsers with the tool called SWD Page Recorder

The only restrictions/limitations:

1. The browser should be started from the tool
2. Internet Explorer Driver Server - IEDriverServer.exe - should be downloaded separately and placed near SwdPageRecorder.exe

Suppose you have TextBox with Id txtName

$("[id*=txtName]").on('keydown', function(e) { 
  var keyCode = e.keyCode || e.which; 
  if (keyCode == 9) {
     e.preventDefault();
     alert('Tab Pressed');
 }
}); 

I'm finding that Tomcat can't seem to find classes defined in other projects, maybe even in the main project. It's failing on the filter definition which is the first definition in web.xml. If I add the project and its dependencies to the server's launch configuration then I just move on to a new error, all of which seems to point to it not setting up the project properly.

Our setup is quite complex. We have multiple components as projects in Eclipse with separate output projects. We have a separate webapp directory which contains the static HTML and images, as well as our WEB-INF.

Eclipse is "Europa Winter release". Tomcat is 6.0.18. I tried version 2.4 and 2.5 of the "Dynamic Web Module" facet.

Thanks for any help!

Yes we can check the length of queue object created from collections.

from collections import deque
class Queue():
    def __init__(self,batchSize=32):
        #self.batchSie = batchSize
        self._queue = deque(maxlen=batchSize)

    def enqueue(self, items):
        ''' Appending the items to the queue'''
        self._queue.append(items)

    def dequeue(self):
        '''remoe the items from the top if the queue becomes full '''
        return self._queue.popleft()

Creating an object of class

q = Queue(batchSize=64)
q.enqueue([1,2])
q.enqueue([2,3])
q.enqueue([1,4])
q.enqueue([1,22])

Now retrieving the length of the queue

#check the len of queue
print(len(q._queue)) 
#you can print the content of the queue
print(q._queue)
#Can check the content of the queue
print(q.dequeue())
#Check the length of retrieved item 
print(len(q.dequeue()))

check the results in attached screen shot

Hope this helps...

You can do it by following way.

ALTER TABLE tableName drop column if exists columnName; 
ALTER TABLE tableName ADD COLUMN columnName character varying(8);

So it will drop the column if it is already exists. And then add the column to particular table.

Beside the methods described in previous answers, you can also use a free execution plan viewer and query optimization tool ApexSQL Plan (which I’ve recently bumped into).

You can install and integrate ApexSQL Plan into SQL Server Management Studio, so execution plans can be viewed from SSMS directly.

Viewing Estimated execution plans in ApexSQL Plan

1. Click the New Query button in SSMS and paste the query text in the query text window. Right click and select the “Display Estimated Execution Plan” option from the context menu.

2. The execution plan diagrams will be shown the Execution Plan tab in the results section. Next right-click the execution plan and in the context menu select the “Open in ApexSQL Plan” option.

3. The Estimated execution plan will be opened in ApexSQL Plan and it can be analyzed for query optimization.

Viewing Actual execution plans in ApexSQL Plan

To view the Actual execution plan of a query, continue from the 2nd step mentioned previously, but now, once the Estimated plan is shown, click the “Actual” button from the main ribbon bar in ApexSQL Plan.

Once the “Actual” button is clicked, the Actual execution plan will be shown with detailed preview of the cost parameters along with other execution plan data.

More information about viewing execution plans can be found by following this link.

Try a new prototype object for each instance of the user defined error type. It allows instanceof checks to behave as usual plus type and message are correctly reported in Firefox and V8 (Chome, nodejs).

function NotImplementedError(message){
    if(NotImplementedError.innercall===undefined){
        NotImplementedError.innercall = true;
        NotImplementedError.prototype = new Error(message);
        NotImplementedError.prototype.name = "NotImplementedError";
        NotImplementedError.prototype.constructor = NotImplementedError;

        return new NotImplementedError(message);
    }
    delete NotImplementedError.innercall;
}

Note that an additional entry will preceed the otherwise correct stack.

It's an old question, but still active as there is no explicit Android feature. And the guys from facebook found a work around - somehow. Today, I found a way that works for me. Not perfect (see remarks at the end of this answer) but it works!

Main idea is, that I update the icon of my app's shortcut, created by the launcher on my home screen. When I want to change something on the shortcut-icon, I remove it first and recreate it with a new bitmap.

Here is the code. It has a button increment. When pressed, the shortcut is replaced with one that has a new counting number.

First you need these two permissions in your manifest:

<uses-permission android:name="com.android.launcher.permission.INSTALL_SHORTCUT" />
<uses-permission android:name="com.android.launcher.permission.UNINSTALL_SHORTCUT" />

Then you need this two methods for installing and uninstalling shortcuts. The shortcutAdd method creates a bitmap with a number in it. This is just to demonstrate that it actually changes. You probably want to change that part with something, you want in your app.

private void shortcutAdd(String name, int number) {
    // Intent to be send, when shortcut is pressed by user ("launched")
    Intent shortcutIntent = new Intent(getApplicationContext(), Play.class);
    shortcutIntent.setAction(Constants.ACTION_PLAY);

    // Create bitmap with number in it -> very default. You probably want to give it a more stylish look
    Bitmap bitmap = Bitmap.createBitmap(100, 100, Bitmap.Config.ARGB_8888);
    Paint paint = new Paint();
    paint.setColor(0xFF808080); // gray
    paint.setTextAlign(Paint.Align.CENTER);
    paint.setTextSize(50);
    new Canvas(bitmap).drawText(""+number, 50, 50, paint);
    ((ImageView) findViewById(R.id.icon)).setImageBitmap(bitmap);

    // Decorate the shortcut
    Intent addIntent = new Intent();
    addIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
    addIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, name);
    addIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON, bitmap);

    // Inform launcher to create shortcut
    addIntent.setAction("com.android.launcher.action.INSTALL_SHORTCUT");
    getApplicationContext().sendBroadcast(addIntent);
}

private void shortcutDel(String name) {
    // Intent to be send, when shortcut is pressed by user ("launched")
    Intent shortcutIntent = new Intent(getApplicationContext(), Play.class);
    shortcutIntent.setAction(Constants.ACTION_PLAY);

    // Decorate the shortcut
    Intent delIntent = new Intent();
    delIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
    delIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, name);

    // Inform launcher to remove shortcut
    delIntent.setAction("com.android.launcher.action.UNINSTALL_SHORTCUT");
    getApplicationContext().sendBroadcast(delIntent);
}

And finally, here are two listener to add the first shortcut and update the shortcut with an incrementing counter.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.test);
    findViewById(R.id.add).setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            shortcutAdd("changeIt!", count);
        }
    });
    findViewById(R.id.increment).setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            shortcutDel("changeIt!");
            count++;
            shortcutAdd("changeIt!", count);
        }
    });
}

Remarks:

• This way works also if your App controls more shortcuts on the home screen, e.g. with different extra's in the Intent. They just need different names so that the right one is uninstalled and reinstalled.

• The programmatical handling of shortcuts in Android is a well known, widely used but not officially supported Android feature. It seems to work on the default launcher and I never tried it anywhere else. So dont blame me, when you get this user-emails "It does not work on my XYZ, double rooted, super blasted phone"

• The launcher writes a Toast when a shortcut was installad and one when a shortcut was uninstalled. So I get two Toasts every time I change the icon. This is not perfect, but well, as long as the rest of my app is perfect...

<?php

    // Get absolute path
    $path = getcwd(); // /home/user/public_html/test/test.php.   

    $path = substr($path, 0, strpos($path, "public_html"));

    $root = $path . "public_html/";

    echo $root; // This will output /home/user/public_html/

maybe you can try this way

SELECT * FROM Product P WHERE (CASE WHEN @Status = 'published' THEN (CASE WHEN P.Status IN (1, 3) THEN 'TRUE' ELSE FALSE END) WHEN @Status = 'standby' THEN (CASE WHEN P.Status IN (2, 5, 9, 6) THEN 'TRUE' ELSE 'FALSE' END) WHEN @Status = 'deleted' THEN (CASE WHEN P.Status IN (4, 5, 8, 10) THEN 'TRUE' ELSE 'FALSE' END) ELSE (CASE WHEN P.Status IN (1, 3) THEN 'TRUE' ELSE 'FALSE' END) END) = 'TRUE'

In this way if @Status = 'published', the query will check if P.Status is among 1 or 3, it will return TRUE else 'FALSE'. This will be matched with TRUE at the end

Hope it helps.

This is how I do you ajax pages... its a pretty easy method...

    function ajax_urls() {
       var objApps= ['ads','user'];
        $("a.ajx").each(function(){
               var url = $(this).attr('href');
               for ( var i=0;i< objApps.length;i++ ) {
                   if (url.indexOf("/"+objApps[i]+"/")>-1) {
                      $(this).attr("href",url.replace("/"+objApps[i]+"/","/"+objApps[i]+"/#p="));
                   }
               }
           });
}

How this works is it basically looks at all URLs that have the class 'ajx' and it replaces a keyword and adds the # sign... so if js is turned off then the urls would act as they normally do... all "apps" (each section of the site) has its own keyword... so all i need to do is add to the js array above to add more pages...

So for example my current settings are set to:

 var objApps= ['ads','user'];

So if i have a url such as:

www.domain.com/ads/3923/bla/dada/bla

the js script would replace the /ads/ part so my URL would end up being

www.domain.com/ads/#p=3923/bla/dada/bla

Then I use jquery bbq plugin to load the page accordingly...

Do you want coordinates relative to the screen or the application?

If it's within the application just use:

Mouse.GetPosition(Application.Current.MainWindow);

If not, I believe you can add a reference to System.Windows.Forms and use:

System.Windows.Forms.Control.MousePosition;

Here is a good tutorial for launching application from within another app:
iOS SDK: Working with URL Schemes
And, it is not possible to launch arbitrary application, but the native applications which registered the URL Schemes.

Even if you have resolved your issue, here is another one try to export csv using mvc.

return new FileStreamResult(fileStream, "text/csv") { FileDownloadName = fileDownloadName };

You should be careful to leave a space between the sign of '[' and double quotes where the variable contains this:

if [ "$s1" == "$s2" ]; then
#   ^     ^  ^     ^
   echo match
fi

The ^s show the blank spaces you need to leave.

C# has a lot of reference types. Even if a container stores the references contiguously, the objects themselves may be scattered through the heap

The solution above won't work if the original string has no spaces.

Try this:

var title = "This is your title";
var shortText = jQuery.trim(title).substring(0, 10)
                          .trim(this) + "...";

You can use ax.figure.savefig(), as suggested in a comment on the question:

import pandas as pd

df = pd.DataFrame([0, 1])
ax = df.plot.line()
ax.figure.savefig('demo-file.pdf')

This has no practical benefit over ax.get_figure().savefig() as suggested in other answers, so you can pick the option you find the most aesthetically pleasing. In fact, get_figure() simply returns self.figure:

# Source from snippet linked above
def get_figure(self):
    """Return the `.Figure` instance the artist belongs to."""
    return self.figure

KeyPress is only fired by printable characters and is fired after the KeyDown event. Depending on the typing delay settings there can be multiple KeyDown and KeyPress events but only one KeyUp event.

I can't tell you what's best, but a tool I have used with success in the past was cx_Freeze. They recently updated (on Jan. 7, '17) to version 5.0.1 and it supports Python 3.6.

Here's the pypi https://pypi.python.org/pypi/cx_Freeze

The documentation shows that there is more than one way to do it, depending on your needs. http://cx-freeze.readthedocs.io/en/latest/overview.html

I have not tried it out yet, so I'm going to point to a post where the simple way of doing it was discussed. Some things may or may not have changed though.

How do I use cx_freeze?

if you want to select some row this will help you

NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];
[someTableView selectRowAtIndexPath:indexPath 
                           animated:NO 
                     scrollPosition:UITableViewScrollPositionNone];

This will also Highlighted the row. Then delegate

 [someTableView.delegate someTableView didSelectRowAtIndexPath:indexPath];

You can add a row to a table in the most easiest way like this :-

I found this as an easiest way to add row . The awesome thing about this is that it doesn't change the already present table contents even if it contains input elements .

row = `<tr><td><input type="text"></td></tr>`
$("#table_body tr:last").after(row) ;

Here #table_body is the id of the table body tag .

I'm writing this answer in 2015, and for some reason (probably older versions of jQuery) none of the other answers have worked for me. I mean, they change the selected index, but it doesn't actually reflect on the actual dropdown.

Here is another way to change the index, and actually have it reflect in the dropdown:

$('#mydropdown').val('first').change();

Or you can use this one http://plugins.jquery.com/project/parseQuery, it's smaller than most (minified 449 bytes), returns an object representing name-value pairs.

I'm calling NewNumber() regularly, but the problem is I often get repeated numbers.

Random.Next doesn't guarantee the number to be unique. Also your range is from 0 to 10 and chances are you will get duplicate values. May be you can setup a list of int and insert random numbers in the list after checking if it doesn't contain the duplicate. Something like:

public Random a = new Random(); // replace from new Random(DateTime.Now.Ticks.GetHashCode());
                                // Since similar code is done in default constructor internally
public List<int> randomList = new List<int>();
int MyNumber = 0;
private void NewNumber()
{
    MyNumber = a.Next(0, 10);
    if (!randomList.Contains(MyNumber))
        randomList.Add(MyNumber);
}

Use finishAffinity(); in task C when starting task A to clear backstack activities.

$('.load_more').live("click",function() { //When user clicks
          var newcurrentpageTemp = parseInt($(this).attr("id")) + 1
          dosomething(newcurrentpageTemp );
      });

In lieu of changing the port, I reclaimed port 80 as being used by IIS.

So I went to services, and stopped the following:

1. World Wide Web Publishing Services.
2. Web Management Service
3. Web Deployment Agent Service.

set them to manual so that it will not start on dev environment restart.

If you're a minimalist like me. Say you only want to render a record with a list containing entries.

<div>
  {data.map((record) => (
    record.list.length > 0
      ? (<YourRenderComponent record={record} key={record.id} />)
      : null
  ))}
</div>

Another scenario could be the existence of multiple database paths. First, make note of the path where new databases are currently being stored. So if you create a new empty database and then do Tasks/Restore, make sure that the path the restore is trying to use is the same directory that the empty database was created in. Even if the restore path is legal, you will still get the access denied error if it is not the current path you are working with. Very easy to spot when the path is not legal, much harder to spot when the path is legal, but not the current path.

type: 'winpty python' and it will work

gitbash has some issues when running any command that starts with python. this goes for any python manage.py commands as well. Always start with 'winpty python manage.py' At least this is what works for me. Running Windows 10.

Also try dojo.number which has built-in localization support. It is a much closer analog to Java's NumberFormat/DecimalFormat

You can also use an object-oriented path with pathlib (available as a standard library as of Python 3.4):

from pathlib import Path

start_path = Path('/my/root/directory')
final_path = start_path / 'in' / 'here'

If you want the structure to have a certain size with GCC for example use __attribute__((packed)).

On Windows you can set the alignment to one byte when using the cl.exe compier with the /Zp option.

Usually it is easier for the CPU to access data that is a multiple of 4 (or 8), depending platform and also on the compiler.

So it is a matter of alignment basically.

You need to have good reasons to change it.

To get the current time's milliseconds, use http://momentjs.com/docs/#/get-set/millisecond/

I once ran into this situation and I had the dependencies in classpath. The solution was to include javax.mail and javax.activation libraries in the container's (eg. tomcat) lib folder. Using maven -set them to provided scope and it should work. You will have shared email libs in classpath for all projects.

... right now it happens only to the website I'm testing. I can't post it here because it's confidential.

Then I guess it is one of the sites which is incompatible with TLS1.2. The openssl as used in 12.04 does not use TLS1.2 on the client side while with 14.04 it uses TLS1.2 which might explain the difference. To work around try to explicitly use --secure-protocol=TLSv1. If this does not help check if you can access the site with openssl s_client -connect ... (probably not) and with openssl s_client -tls1 -no_tls1_1, -no_tls1_2 ....

Please note that it might be other causes, but this one is the most probable and without getting access to the site everything is just speculation anyway.

The assumed problem in detail: Usually clients use the most compatible handshake to access a server. This is the SSLv23 handshake which is compatible to older SSL versions but announces the best TLS version the client supports, so that the server can pick the best version. In this case wget would announce TLS1.2. But there are some broken servers which never assumed that one day there would be something like TLS1.2 and which refuse the handshake if the client announces support for this hot new version (from 2008!) instead of just responding with the best version the server supports. To access these broken servers the client has to lie and claim that it only supports TLS1.0 as the best version.

Is Ubuntu 14.04 or wget 1.15 not compatible with TLS 1.0 websites? Do I need to install/download any library/software to enable this connection?

The problem is the server, not the client. Most browsers work around these broken servers by retrying with a lower version. Most other applications fail permanently if the first connection attempt fails, i.e. they don't downgrade by itself and one has to enforce another version by some application specific settings.

There are plenty of answers on SO and good posts on the web about mocking. One place that you might want to start looking is the post by Martin Fowler Mocks Aren't Stubs where he discusses a lot of the ideas of mocking.

In one paragraph - Mocking is one particlar technique to allow testing of a unit of code with out being reliant upon dependencies. In general, what differentiates mocking from other methods is that mock objects used to replace code dependencies will allow expectations to be set - a mock object will know how it is meant to be called by your code and how to respond.

Your original question mentioned TypeMock, so I've left my answer to that below:

TypeMock is the name of a commercial mocking framework.

It offers all the features of the free mocking frameworks like RhinoMocks and Moq, plus some more powerful options.

Whether or not you need TypeMock is highly debatable - you can do most mocking you would ever want with free mocking libraries, and many argue that the abilities offered by TypeMock will often lead you away from well encapsulated design.

As another answer stated 'TypeMocking' is not actually a defined concept, but could be taken to mean the type of mocking that TypeMock offers, using the CLR profiler to intercept .Net calls at runtime, giving much greater ability to fake objects (not requirements such as needing interfaces or virtual methods).

You can use localStorage. This is the Html5 equivalent of cookies. It appears to work on Chrome and Firefox BUT on Firefox, I needed to upload it to a server. That is, testing directly on my home computer didn't work.

I'm working up HTML5 examples. Go to http://faculty.purchase.edu/jeanine.meyer/html5/html5explain.html and scroll to the maze one. The information to re-build the maze is stored using localStorage.

I came to this article looking for HTML5 JavaScript for loading and working with xml files. Is it the same as older html and JavaScript????

Strip won't work. It only removes leading and trailing instances, not everything in between: http://docs.python.org/2/library/stdtypes.html#str.strip

Having fun with filter:

import string
asking = "hello! what's your name?"
predicate = lambda x:x not in string.punctuation
filter(predicate, asking)

This is just an explanation not addressed in other answers

At least in recent versions of Mysql, your first query is not committed.

If you query it under the same session you will see the changes, but if you query it from a different session, the changes are not there, they are not committed.

What's going on?

When you open a transaction, and a query inside it fails, the transaction keeps open, it does not commit nor rollback the changes.

So BE CAREFUL, any table/row that was locked with a previous query likeSELECT ... FOR SHARE/UPDATE, UPDATE, INSERT or any other locking-query, keeps locked until that session is killed (and executes a rollback), or until a subsequent query commits it explicitly (COMMIT) or implicitly, thus making the partial changes permanent (which might happen hours later, while the transaction was in a waiting state).

That's why the solution involves declaring handlers to immediately ROLLBACK when an error happens.

Extra

Inside the handler you can also re-raise the error using RESIGNAL, otherwise the stored procedure executes "Successfully"

BEGIN
    DECLARE EXIT HANDLER FOR SQLEXCEPTION 
        BEGIN
            ROLLBACK;
            RESIGNAL;
        END;

    START TRANSACTION;
        #.. Query 1 ..
        #.. Query 2 ..
        #.. Query 3 ..
    COMMIT;
END

Adding another solution similar to @domi's with parsing mathematical symbols, superscript, subscript, parenthesis/bracket, .etc.

# `bgroup` to make adding `)` possible

            label = as.character(expression(paste("Log"["10"], bgroup("(", frac("x", "y"), ")")))))

### OR create new variables then assign labels directly

I faced the same problem of text wrapping, solved it by changing the css of table class in DT_bootstrap.css. I introduced last two css lines table-layout and word-break.

   table.table {
    clear: both;
    margin-bottom: 6px !important;
    max-width: none !important;
    table-layout: fixed;
    word-break: break-all;
   } 

This is actually an area ripe for discussion, with many subtle techniques available. It is important that you select/develop a technique that meets your needs including: screen readers, images/css/scripting on/off combinations, seo, etc.

Here are some good resources to get started down the road of standardista image replacement techniques:

You can use this function (works in PHP Version >= 5.3):

function sortArrayByKey(&$array,$key,$string = false,$asc = true){
    if($string){
        usort($array,function ($a, $b) use(&$key,&$asc)
        {
            if($asc)    return strcmp(strtolower($a{$key}), strtolower($b{$key}));
            else        return strcmp(strtolower($b{$key}), strtolower($a{$key}));
        });
    }else{
        usort($array,function ($a, $b) use(&$key,&$asc)
        {
            if($a[$key] == $b{$key}){return 0;}
            if($asc) return ($a{$key} < $b{$key}) ? -1 : 1;
            else     return ($a{$key} > $b{$key}) ? -1 : 1;

        });
    }
}

Example:

sortArrayByKey($yourArray,"name",true); //String sort (ascending order)
sortArrayByKey($yourArray,"name",true,false); //String sort (descending order)
sortArrayByKey($yourArray,"id"); //number sort (ascending order)
sortArrayByKey($yourArray,"count",false,false); //number sort (descending order)

1. git checkout [branchYouWantToReceiveBranch] - checkout branch you want to receive branch
2. git merge [branchYouWantToMergeIntoBranch]

Change

Range(DataImportColumn & DataImportRow).Offset(0, 2).Value

to

Cells(DataImportRow,DataImportColumn).Value

When you just have the row and the column then you can use the cells() object. The syntax is Cells(Row,Column)

Also one more tip. You might want to fully qualify your Cells object. for example

ThisWorkbook.Sheets("WhatEver").Cells(DataImportRow,DataImportColumn).Value

I understand this is an old post but would like to provide SQL that i came up with

DECLARE @value DECIMAL(23,3)
set @value = 1.2000
select @value original_val, 
    SUBSTRING(  CAST( @value as VARCHAR(100)), 
                0,
                PATINDEX('%.%',CAST(@value as VARCHAR(100)))
            )
      + CASE WHEN ROUND( 
                        REVERSE( SUBSTRING( CAST(@value as VARCHAR(100)),
                                        PATINDEX('%.%',CAST(@value as VARCHAR(100)))+1,
                                        LEN(CAST(@value as VARCHAR(100)))
                                        )
                                )
                    ,1) > 0 THEN 
            '.' 
            +  REVERSE(ROUND(REVERSE(SUBSTRING( CAST(@value as VARCHAR(100)),
                                                PATINDEX('%.%',CAST(@value as VARCHAR(100)))+1,
                                                LEN(CAST(@value as VARCHAR(100)))
                                                )
                ),1))
        ELSE '' END  AS modified_val

just use a Button with android:drawableRight properties like this:

<Button android:id="@+id/btnNovaCompra" android:layout_width="wrap_content"
        android:text="@string/btn_novaCompra"
        android:gravity="center"
        android:drawableRight="@drawable/shoppingcart"
        android:layout_height="wrap_content"/>

The other answer is very complete, but here is a rule of thumb:

• call is blocking:

  call('notepad.exe')
  print('hello')  # only executed when notepad is closed
  

• Popen is non-blocking:

  Popen('notepad.exe')
  print('hello')  # immediately executed
  

SELECT * FROM users WHERE created >= NOW();

if the column is datetime type.

jQuery('input[name="inputName"]:checked').val()

typeOf is a C# keyword that is used when you have the name of the class. It is calculated at compile time and thus cannot be used on an instance, which is created at runtime. GetType is a method of the object class that can be used on an instance.

This method was posted by @lauthiamkok in the comments. I'm posting it here as an answer to call more attention to it.

Depending on your needs, you should consider using filter_var() with the FILTER_VALIDATE_BOOLEAN flag.

filter_var(    true, FILTER_VALIDATE_BOOLEAN); // true
filter_var(    'true', FILTER_VALIDATE_BOOLEAN); // true
filter_var(         1, FILTER_VALIDATE_BOOLEAN); // true
filter_var(       '1', FILTER_VALIDATE_BOOLEAN); // true
filter_var(      'on', FILTER_VALIDATE_BOOLEAN); // true
filter_var(     'yes', FILTER_VALIDATE_BOOLEAN); // true

filter_var(   false, FILTER_VALIDATE_BOOLEAN); // false
filter_var(   'false', FILTER_VALIDATE_BOOLEAN); // false
filter_var(         0, FILTER_VALIDATE_BOOLEAN); // false
filter_var(       '0', FILTER_VALIDATE_BOOLEAN); // false
filter_var(     'off', FILTER_VALIDATE_BOOLEAN); // false
filter_var(      'no', FILTER_VALIDATE_BOOLEAN); // false
filter_var('asdfasdf', FILTER_VALIDATE_BOOLEAN); // false
filter_var(        '', FILTER_VALIDATE_BOOLEAN); // false
filter_var(      null, FILTER_VALIDATE_BOOLEAN); // false

In Windows, you will have to set the path to the location where you installed Anaconda3 to.

For me, I installed anaconda3 into C:\Anaconda3. Therefore you need to add C:\Anaconda3 as well as C:\Anaconda3\Scripts\ to your path variable, e.g. set PATH=%PATH%;C:\Anaconda3;C:\Anaconda3\Scripts\.

You can do this via powershell (see above, https://msdn.microsoft.com/en-us/library/windows/desktop/bb776899(v=vs.85).aspx ), or hit the windows key ? enter environment ? choose from settings ? edit environment variables for your account ? select Path variable ? Edit ? New.

To test it, open a new dos shell, and you should be able to use conda commands now. E.g., try conda --version.

Here is a simple function to do this for you:

def precision(num,x):
    return "{0:.xf}".format(round(num))

Here, num is the decimal number. x is the decimal up to where you want to round a floating number.

The advantage over other implementation is that it can fill zeros at the right end of the decimal to make a deciaml number up to x decimal places.

Example 1:

precision(10.2, 9)

will return

10.200000000 (up to 9 decimal points)

Example 2:

precision(10.2231, 2)

will return

10.22 (up to two decimal points)

For visual learners, when defining the function without .prototype

ExampleClass = function(){};
ExampleClass.method = function(customString){
             console.log((customString !== undefined)? 
                          customString : 
                          "called from func def.");}
ExampleClass.method(); // >> output: `called from func def.`  

var someInstance = new ExampleClass();
someInstance.method('Called from instance');
    // >> error! `someInstance.method is not a function`  

With same code, if .prototype is added,

ExampleClass.prototype.method = function(customString){
             console.log((customString !== undefined)? 
                          customString : 
                          "called from func def.");}
ExampleClass.method();  
      // > error! `ExampleClass.method is not a function.`  

var someInstance = new ExampleClass();
someInstance.method('Called from instance');
                 // > output: `Called from instance`

To make it clearer,

ExampleClass = function(){};
ExampleClass.directM = function(){}  //M for method
ExampleClass.prototype.protoM = function(){}

var instanceOfExample = new ExampleClass();

ExampleClass.directM();     ? works
instanceOfExample.directM();   x Error!

ExampleClass.protoM();     x Error!
instanceOfExample.protoM();  ? works

****Note for the example above, someInstance.method() won't be executed as,
ExampleClass.method() causes error & execution cannot continue.
But for the sake of illustration & easy understanding, I've kept this sequence.****

You can't transition between two background images, as there's no way for the browser to know what you want to interpolate. As you've discovered, you can transition the background position. If you want the image to fade in on mouse over, I think the best way to do it with CSS transitions is to put the image on a containing element and then animate the background colour to transparent on the link itself:

span {
    background: url(button.png) no-repeat 0 0;
}
a {
    width: 32px;
    height: 32px;
    text-align: left;
    background: rgb(255,255,255);

    -webkit-transition: background 300ms ease-in 200ms; /* property duration timing-function delay */
    -moz-transition: background 300ms ease-in 200ms;
    -o-transition: background 300ms ease-in 200ms;
    transition: background 300ms ease-in 200ms;
    }
a:hover {
    background: rgba(255,255,255,0);
}

I was using Eclipse Juno and I didn't remember if it was 32 or 64 bits. I installed Java 32 bits and that's why it failed. I then installed Java 64 bits and Eclipse Juno is working again.

I also removed any java or jre reference in my environment variables (PATH).

Here are some dplyr options:

# by column type:
df %>% 
  mutate_if(is.factor, ~as.numeric(as.character(.)))

# by specific columns:
df %>% 
  mutate_at(vars(x, y, z), ~as.numeric(as.character(.))) 

# all columns:
df %>% 
  mutate_all(~as.numeric(as.character(.))) 

I'm one of the developers for Twitterrific and to be honest, I can't tell you how many hours have gone into the product. I can tell you everyone who upvoted the estimate of 160 hours for development and 40 hours for design is fricken' high. (I'd use another phrase, but this is my first post on Stack Overflow, so I'm being good.)

Twitterrific has had 4 major releases beginning with the iOS 1.0 (Jailbreak.) That's a lot of code, much of which is in the bit bucket (we refactor a lot with each major release.)

One thing that would be interesting to look at is the amount of time that we had to work on the iPad version. Apple set a product release date that gave us 60 days to do the development. (That was later extended by a week.)

We started the iPad development from scratch, but a lot of our underlying code (mostly models) was re-used. The development was done by two experienced iOS developers. One of them has even written a book: http://appdevmanual.com :-)

With such a short schedule, we worked some pretty long hours. Let's be conservative and say it's 10 hours per day for 6 days a week. That 60 hours for 9 weeks gives us 540 hours. With two developers, that's pretty close to 1,100 hours. Our rate for clients is $150 per hour giving $165,000 just for new code. Remember also that we were reusing a bunch existing code: I'm going to lowball the value of that code at $35,000 giving a total development cost of $200,000.

Anyone who's done serious iPhone development can tell you there's a lot of design work involved with any project. We had two designers working on that aspect of the product. They worked their asses off dealing with completely new interaction mechanics. Don't forget they didn't have any hardware to touch, either (LOTS of printouts!) Combined they spent at least 25 hours per week on the project. So 225 hours at $150/hr is about $34,000.

There are also other costs that many developer neglect to take into account: project management, testing, equipment. Again, if we lowball that figure at $16,000 we're at $250,000. This number falls in line with Jonathan Wight's (@schwa) $50-150K estimate with the 22 day Obama app.

Take another hit, dude.

Now if you want to build backend services for your app, that number's going to go up even more. Everyone seems surprised that Instagram chewed through $500K in venture funding to build a new frontend and backend. I'm not.

I think you're mixed up between PATH and PYTHONPATH. All you have to do to run a 'script' is have it's parental directory appended to your PATH variable. You can test this by running

which myscript.py

Also, if myscripy.py depends on custom modules, their parental directories must also be added to the PYTHONPATH variable. Unfortunately, because the designers of python were clearly on drugs, testing your imports in the repl with the following will not guarantee that your PYTHONPATH is set properly for use in a script. This part of python programming is magic and can't be answered appropriately on stackoverflow.

$python
Python 2.7.8 blahblahblah
...
>from mymodule.submodule import ClassName
>test = ClassName()
>^D
$myscript_that_needs_mymodule.submodule.py

Do you really have to do it with jQuery? You can attach the onload event directly to your image as well;

<img src="/path/to/image.jpg" onload="doStuff(this);" />

It will fire every time the image has loaded, from cache or not.

Update 2020

as requested by @baxxx, here is an update because random.rand is deprecated meanwhile.

This works with matplotlip 3.2.1:

from matplotlib import pyplot as plt
import random
import numpy as np

random = np.random.random ([8,90])

plt.figure(figsize = (20,2))
plt.imshow(random, interpolation='nearest')

This plots:

To change the random number, you can experiment with np.random.normal(0,1,(8,90)) (here mean = 0, standard deviation = 1).

After some research I finally got a VBA code to show the filter value in another cell:

Dim bRepresentAsRange As Boolean, bRangeBroken As Boolean
Dim sSelection As String
Dim tbl As Variant
bRepresentAsRange = False
bRangeBroker = False

With Worksheets("Forecast").PivotTables("ForecastbyDivision")
            ReDim tbl(.PageFields("Probability").PivotItems.Count)
            For Each fld In .PivotFields("Probability").PivotItems

                If fld.Visible Then
                    tbl(n) = fld.Name
                    sSelection = sSelection & fld.Name & ","
                    n = n + 1
                    bRepresentAsRange = True
                Else
                    If bRepresentAsRange Then
                        bRepresentAsRange = False
                        bRangeBroken = True
                    End If
                End If

            Next fld

            If Not bRangeBroken Then
                Worksheets("Forecast").Range("ProbSelection") = " >= " & tbl(0)
            Else
                Worksheets("Forecast").Range("ProbSelection") = Left(sSelection, Len(sSelection) - 1)
            End If

        End With

because I lost more than 2 hours to center a very wide image,
for me with a image dimendion of 2500x100px and viewport 1600x1200 or Full HD 1900x1200 works centered like that:

 .imageContainer {
  height: 100px;
  overflow: hidden;
  position: relative;
 }
 .imageCenter {
  width: auto;
  position: absolute;
  left: -10%;
  top: 0;
  margin-left: -500px;
 }
.imageCenter img {
 display: block;
 margin: 0 auto;
 }

I Hope this helps others to finish faster the task :)

Have you looked at the Maven Dependency Plugin ? That won't remove stuff for you but has tools to allow you to do the analysis yourself. I'm thinking particularly of

mvn dependency:tree

I think the simplest way which worked for me to find Command line tools is installed or not and its version irrespective of what macOS version is

$brew config

macOS: 10.14.2-x86_64
CLT: 10.1.0.0.1.1539992718
Xcode: 10.1

This when you have Command Line tools properly installed and paths set properly.

Earlier i got output as below
macOS: 10.14.2-x86_64
CLT: N/A
Xcode: 10.1

CLT was shown as N/A in spite of having gcc and make working fine and below outputs

$xcode-select -p              
/Applications/Xcode.app/Contents/Developer
$pkgutil --pkg-info=com.apple.pkg.CLTools_Executables
No receipt for 'com.apple.pkg.CLTools_Executables' found at '/'.
$brew doctor
Your system is ready to brew.

Finally doing xcode-select --install resolved my issue of brew unable to find CLT for installing packages as below.

Installing sphinx-doc dependency: python
Warning: Building python from source:
  The bottle needs the Apple Command Line Tools to be installed.
  You can install them, if desired, with:
    xcode-select --install

Subversion implicitly has the remote repository associated with it at all times. Git, on the other hand, allows many "remotes", each of which represents a single remote place you can push to or pull from.

You need to add a remote for the GitHub repository to your local repository, then use git push ${remote} or git pull ${remote} to push and pull respectively - or the GUI equivalents.

Pro Git discusses remotes here: http://git-scm.com/book/ch2-5.html

The GitHub help also discusses them in a more "task-focused" way here: http://help.github.com/remotes/

Once you have associated the two you will be able to push or pull branches.

I know this is a an old question but wanted to share what I thought was a useful way of extending UITextView to have placeholderText and placeholderColor fields. Basically you cast the UITextView into a UITextField and then set the attributedPlaceholder field. PlaceholderText and placeholderColor are IBInspectable fields, so their values can be set in IB and behaves exactly as the UITextField placeholder functionality.

UITextView+Extend.h

#import <UIKit/UIKit.h>

@interface UITextView (Extend)

@property (nonatomic) IBInspectable NSString *placeholderText;
@property (nonatomic) IBInspectable UIColor *placeholderColor;

@end

UITextView+Extend.m

#import "UITextView+Extend.h"
#import "objc/runtime.h"

@implementation UITextView (Extend)

- (void)setPlaceholderText:(NSString *)placeholderText
{
    objc_setAssociatedObject(self, @selector(placeholderText), placeholderText, OBJC_ASSOCIATION_RETAIN_NONATOMIC);
    [self updatePlaceholderText];
}

- (NSString*)placeholderText
{
    return objc_getAssociatedObject(self, @selector(placeholderText));
}

- (void)setPlaceholderColor:(UIColor *)placeholderColor
{
    objc_setAssociatedObject(self, @selector(placeholderColor), placeholderColor, OBJC_ASSOCIATION_RETAIN_NONATOMIC);
    [self updatePlaceholderText];
}

- (UIColor*)placeholderColor
{
    return objc_getAssociatedObject(self, @selector(placeholderColor));
}

- (void)updatePlaceholderText
{
    NSString *text = self.placeholderText;
    UIColor *color = self.placeholderColor;
    if(text && color)
    {
        UITextField *textField = (UITextField*)self;
        textField.attributedPlaceholder = [[NSAttributedString alloc] initWithString:text attributes:@{NSForegroundColorAttributeName:color}];
    }
}

@end

Just zero off the time element of the date. e.g.

SELECT DATEADD(dd, DATEDIFF(dd, 0, getdate()), 0)

I've used GetDate as that's an MSSQL function, as you've tagged, but Now() is probably MySQL or you're using the ODBC function call, still should work if you just replace one with the other.

I had to turn PAE/NX off and then back to on...voila !!

After doing some testing, building upon the suggestions in the previous answers, there seem to be two usable solutions.

Method 1 is fastest, but less powerful in terms of matching more complex patterns.
Method 2 is more flexible, but slower.

Method 1 - fastest
I've tested this method on a table with 1 million rows.
It seems to be 3.8 times faster than the regex solutions.
The 0-replacement solves the issue that 0 is mapped to a space, and does not seem to slow down the query.

SELECT *
FROM <table>
WHERE TRANSLATE(replace(<char_column>,'0',''),'0123456789',' ') IS NOT NULL;

Method 2 - slower, but more flexible
I've compared the speed of putting the negation inside or outside the regex statement. Both are equally slower than the translate-solution. As a result, @ciuly's approach seems most sensible when using regex.

SELECT *
FROM <table>
WHERE NOT REGEXP_LIKE(<char_column>, '^[0-9]+$');

In my case, I was using Nginx in front of my application with the following configuration:

location / {
     proxy_pass        http://localhost:8080/;
     proxy_set_header  X-Real-IP $remote_addr;
     proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
     proxy_set_header  Host $http_host;
     add_header Content-Security-Policy 'upgrade-insecure-requests';
}

so in my application I get the real user ip like so:

String clientIP = request.getHeader("X-Real-IP");

I faced the same issue. Setting relative path of the parent in module projects solved the issue.

Use <relativePath>../Parent Project Name/pom.xml</relativePath>

Using Process.Start on explorer.exe with the /select argument oddly only works for paths less than 120 characters long.

I had to use a native windows method to get it to work in all cases:

[DllImport("shell32.dll", SetLastError = true)]
public static extern int SHOpenFolderAndSelectItems(IntPtr pidlFolder, uint cidl, [In, MarshalAs(UnmanagedType.LPArray)] IntPtr[] apidl, uint dwFlags);

[DllImport("shell32.dll", SetLastError = true)]
public static extern void SHParseDisplayName([MarshalAs(UnmanagedType.LPWStr)] string name, IntPtr bindingContext, [Out] out IntPtr pidl, uint sfgaoIn, [Out] out uint psfgaoOut);

public static void OpenFolderAndSelectItem(string folderPath, string file)
{
    IntPtr nativeFolder;
    uint psfgaoOut;
    SHParseDisplayName(folderPath, IntPtr.Zero, out nativeFolder, 0, out psfgaoOut);

    if (nativeFolder == IntPtr.Zero)
    {
        // Log error, can't find folder
        return;
    }

    IntPtr nativeFile;
    SHParseDisplayName(Path.Combine(folderPath, file), IntPtr.Zero, out nativeFile, 0, out psfgaoOut);

    IntPtr[] fileArray;
    if (nativeFile == IntPtr.Zero)
    {
        // Open the folder without the file selected if we can't find the file
        fileArray = new IntPtr[0];
    }
    else
    {
        fileArray = new IntPtr[] { nativeFile };
    }

    SHOpenFolderAndSelectItems(nativeFolder, (uint)fileArray.Length, fileArray, 0);

    Marshal.FreeCoTaskMem(nativeFolder);
    if (nativeFile != IntPtr.Zero)
    {
        Marshal.FreeCoTaskMem(nativeFile);
    }
}

If you already fetched your remote branch and do git branch -a,
you obtain something like :

* 8.0
  xxx
  remotes/origin/xxx
  remotes/origin/8.0
  remotes/origin/HEAD -> origin/8.0
  remotes/rep_mirror/8.0

After that, you can use rep_mirror/8.0 to designate locally your remote branch.

The trick is that remotes/rep_mirror/8.0 doesn't work but rep_mirror/8.0 does.

So, a command like git merge -m "my msg" rep_mirror/8.0 do the merge.

(note : this is a comment to @VonC answer. I put it as another answer because code blocks don't fit into the comment format)

There is no such syntax in SQL Server, though CREATE TABLE AS ... SELECT does exist in PDW. In SQL Server you can use this query to create an empty table:

SELECT * INTO schema.newtable FROM schema.oldtable WHERE 1 = 0;

(If you want to make a copy of the table including all of the data, then leave out the WHERE clause.)

Note that this creates the same column structure (including an IDENTITY column if one exists) but it does not copy any indexes, constraints, triggers, etc.

I am going to post this because this is what I am currently using for my site and it works in both Google Chrome and IE 10 without receiving any popup messages:

<html>
    <head>
    </head>
    <body onload="window.close();">
    </body>
</html>

I have a function on my site that I want to run to save an on/off variable to session without directly going to a new page so I just open a tiny popup webpage. That webpage then closes itself immediately with the onload="window.close();" function.

I found no answer to my satisfaction, so I figured out myself.

Here is the answer to you if you want to add external source codes to your project and don't want to copy over the entire codes. I have many dependencies on other gits and they are updated hourly if not minutely. I can't do copy every hour to sync up. Here is what you need to do.

Assume this is structure:

/root/projA/src

/root/projA/includes

/root/projB/src

/root/projB/includes

/root/yourProj/src

/root/yourProj/includes

1. Start your VS solution.
2. Right-click the project name right below the Solution.
3. Then click the "Add", "New Filter", put the name "projA" for projA.
4. Right-click on the "projA", click "Add", "New Filter", enter name "src"
5. Right-click on the "projA", click "Add", "New Filter", enter name "includes"
6. Right-click "projA"/"src", click "Add", "Existing Item", then browse to the /root/projA/src to add all source codes or one by one for the ones you want.
7. Do same for "projA"/"includes"

8. Do same for projB. Now the external/existing projects outside yours are present in your solution/project. The VS will compile them together. Here is an trick. Since the projA and projB are virtual folders under your project, the compiler may not find the projA/includes.

9. If it doesn't find the projA/includes, then right click the project, select the "Properties".

10. Navigate to "C/C++". Edit "Additional Include Directories", add your projA/include as such "../projA/includes", relative path.

One caveat, if there are duplicated include/header files, the "exclude from project" on the "Header file" doesn't really work. It's a bug in VS.

I believe this is much simpler;

dynamic obj = JObject.Parse(jsonString);
string results  = obj.results;
foreach(string result in result.Split('))
{
//Todo
}

You can use deparse and substitute to get the name of a function argument:

myfunc <- function(v1) {
  deparse(substitute(v1))
}

myfunc(foo)
[1] "foo"

You can use method named compareTo, x.compareTo(y). It will return 0 if x and y are equal, 1 if x is greater than y and -1 if x is smaller than y

An old tip...

var daddy = window.self;
daddy.opener = window.self;
daddy.close();

You are not allowed to use the concatenation operator with the case statement. One possible solution is to use a variable within the process:

process(b0,b1,b2,b3)
   variable bcat : std_logic_vector(0 to 3);
begin
   bcat := b0 & b1 & b2 & b3;
   case bcat is
      when "0000" => x <= 1;
      when others => x <= 2;
   end case;
end process;

It seems you just need to add padding to your bytes before decoding. There are many other answers on this question, but I want to point out that (at least in Python 3.x) base64.b64decode will truncate any extra padding, provided there is enough in the first place.

So, something like: b'abc=' works just as well as b'abc==' (as does b'abc=====').

What this means is that you can just add the maximum number of padding characters that you would ever need—which is three (b'===')—and base64 will truncate any unnecessary ones.

This lets you write:

base64.b64decode(s + b'===')

which is simpler than:

base64.b64decode(s + b'=' * (-len(s) % 4))

When you call startActivity on the last activity you could always use

Intent.FLAG_ACTIVITY_CLEAR_TOP

as a flag on that intent.

Please use an existing secure PHP encryption library

It's generally a bad idea to write your own cryptography unless you have experience breaking other peoples' cryptography implementations.

None of the examples here authenticate the ciphertext, which leaves them vulnerable to bit-rewriting attacks.

If you can install PECL extensions, libsodium is even better

<?php
// PECL libsodium 0.2.1 and newer

/**
 * Encrypt a message
 * 
 * @param string $message - message to encrypt
 * @param string $key - encryption key
 * @return string
 */
function safeEncrypt($message, $key)
{
    $nonce = \Sodium\randombytes_buf(
        \Sodium\CRYPTO_SECRETBOX_NONCEBYTES
    );

    return base64_encode(
        $nonce.
        \Sodium\crypto_secretbox(
            $message,
            $nonce,
            $key
        )
    );
}

/**
 * Decrypt a message
 * 
 * @param string $encrypted - message encrypted with safeEncrypt()
 * @param string $key - encryption key
 * @return string
 */
function safeDecrypt($encrypted, $key)
{   
    $decoded = base64_decode($encrypted);
    $nonce = mb_substr($decoded, 0, \Sodium\CRYPTO_SECRETBOX_NONCEBYTES, '8bit');
    $ciphertext = mb_substr($decoded, \Sodium\CRYPTO_SECRETBOX_NONCEBYTES, null, '8bit');

    return \Sodium\crypto_secretbox_open(
        $ciphertext,
        $nonce,
        $key
    );
}    

Then to test it out:

<?php
// This refers to the previous code block.
require "safeCrypto.php"; 

// Do this once then store it somehow:
$key = \Sodium\randombytes_buf(\Sodium\CRYPTO_SECRETBOX_KEYBYTES);
$message = 'We are all living in a yellow submarine';

$ciphertext = safeEncrypt($message, $key);
$plaintext = safeDecrypt($ciphertext, $key);

var_dump($ciphertext);
var_dump($plaintext);

This can be used in any situation where you are passing data to the client (e.g. encrypted cookies for sessions without server-side storage, encrypted URL parameters, etc.) with a reasonably high degree of certainty that the end user cannot decipher or reliably tamper with it.

Since libsodium is cross-platform, this also makes it easier to communicate with PHP from, e.g. Java applets or native mobile apps.

Note: If you specifically need to add encrypted cookies powered by libsodium to your app, my employer Paragon Initiative Enterprises is developing a library called Halite that does all of this for you.

I noticed that bash automatically escapes some characters when using auto-complete.

For example, if you have a directory named dir:A, bash will auto-complete to dir\:A

Using this, I runned some experiments using characters of the ASCII table and derived the following lists:

Characters that bash escapes on auto-complete: (includes space)

 !"$&'()*,:;<=>?@[\]^`{|}

Characters that bash does not escape:

#%+-.0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ_abcdefghijklmnopqrstuvwxyz~

(I excluded /, as it cannot be used in directory names)

In the first code block, you're never using the str parameter. Did you mean to say the following?

testFunc = function(str, callback) {
    $.ajax({
        type: 'POST',
        url: 'http://www.myurl.com',
        data: str,
        success: callback
    });
}

It's possible that you're not fetching the Joined Set. Be sure to include the set in your HQL:

public List<Node> getAll() {
    Session session = sessionFactory.getCurrentSession();
    Query query = session.createQuery("FROM Node as n LEFT JOIN FETCH n.nodeValues LEFT JOIN FETCH n.nodeStats");
    return  query.list();
}

Where your class has 2 sets like:

public class Node implements Serializable {

@OneToMany(fetch=FetchType.LAZY)
private Set<NodeValue> nodeValues;

@OneToMany(fetch=FetchType.LAZY)
private Set<NodeStat> nodeStats;

}

To get the key IDs (8 bytes, 16 hex digits), this is the command which worked for me in GPG 1.4.16, 2.1.18 and 2.2.19:

gpg --list-packets <key.asc | awk '$1=="keyid:"{print$2}'

To get some more information (in addition to the key ID):

gpg --list-packets <key.asc

To get even more information:

gpg --list-packets -vvv --debug 0x2 <key.asc

The command

gpg --dry-run --import <key.asc

also works in all 3 versions, but in GPG 1.4.16 it prints only a short (4 bytes, 8 hex digits) key ID, so it's less secure to identify keys.

Some commands in other answers (e.g. gpg --show-keys, gpg --with-fingerprint, gpg --import --import-options show-only) don't work in some of the 3 GPG versions above, thus they are not portable when targeting multiple versions of GPG.

FWIW, I didn't have any success with the spring.resources.static-locations recommended above; what worked for me was setting spring.thymeleaf.prefix:

report.location=file:/Users/bill/report/html/
spring.thymeleaf.prefix=${report.location}

You need to add some arguments. Also, instancing and opening can be put in one line:

fstream file("test.txt", fstream::in | fstream::out | fstream::trunc);

While this may be an old question with lots of answers, I ran across a similar issue and none of the answers were quite what I wanted and/or were poorly explained. The issue with selectionStart and selectionEnd properties is that they don't exist for input type number (while the question was asked for text type, I reckon it might help others who might have other input types that they need to focus). So if you don't know whether the input type the function will focus is a type number or not, you cannot use that solution.

The solution that works cross browser and for all input types is rather simple:

• get and store the value of input in a variable
• focus the input
• set the value of input to the stored value

That way the cursor is at the end of the input element.
So all you'd do is something like this (using jquery, provided the element selector that one wishes to focus is accessible via 'data-focus-element' data attribute of the clicked element and the function executes after clicking on '.foo' element):

$('.foo').click(function() {
    element_selector = $(this).attr('data-focus-element');
    $focus = $(element_selector);
    value = $focus.val();
    $focus.focus();
    $focus.val(value);
});

Why does this work? Simply, when the .focus() is called, the focus will be added to the beginning of the input element (which is the core problem here), ignoring the fact, that the input element already has a value in it. However, when the value of an input is changed, the cursor is automatically placed at the end of the value inside input element. So if you override the value with the same value that had been previously entered in the input, the value will look untouched, the cursor will, however, move to the end.

df.loc will do the job :

>>> df = pd.DataFrame(np.random.randn(3, 2), columns=['A','B'])
>>> df
          A         B
0 -0.269036  0.534991
1  0.069915 -1.173594
2 -1.177792  0.018381
>>> df.loc[13] = df.loc[1]
>>> df
           A         B
0  -0.269036  0.534991
1   0.069915 -1.173594
2  -1.177792  0.018381
13  0.069915 -1.173594
