Necro'ing this Question ;)

You need to change the data being sent as Stringified JSON, that way you can modularize the Ajax call into a single supportable function.

First Step: Extract data construction

/***
 * This helper is used to call WebMethods from the page WebMethods.aspx
 * 
 * @method - String value; the name of the Web Method to execute
 * @data - JSON Object; the JSON structure data to pass, it will be Stringified
 *      before sending
 * @beforeSend - Function(xhr, sett)
 * @success - Function(data, status, xhr)
 * @error - Function(xhr, status, err)
 */
function AddToCartAjax(method, data, beforeSend, success, error) {
    $.ajax({
        url: 'AddToCart.aspx/', + method,
        data: JSON.stringify(data),
        type: "POST",
        dataType: "json",
        contentType: "application/json; charset=utf-8",
        beforeSend: beforeSend,
        success: success,
        error: error
    })
}

Second Step: Generalize WebMethod

[WebMethod]
public static string AddTo_Cart ( object items ) {
    var js = new JavaScriptSerializer();
    var json = js.ConvertToType<Dictionary<string , int>>( items );

    SpiritsShared.ShoppingCart.AddItem(json["itemId"], json["quantity"]);      
    return "Add";
}

Third Step: Call it where you need it

This can be called just about anywhere, JS-file, HTML-file, or Server-side construction.

var items = { "quantity": total_qty, "itemId": itemId };

AddToCartAjax("AddTo_Cart", items,
    function (xhr, sett) {  // @beforeSend
        alert("Start!!!");
    }, function (data, status, xhr) {   // @success
        alert("a");
    }, function(xhr, status, err){  // @error
        alert("Sorry!!!");
    });

On the Server, to Serialize/Deserialize json to custom objects:

public static string Serialize<T>(T obj)
{
    DataContractJsonSerializer serializer = new DataContractJsonSerializer(obj.GetType());
    MemoryStream ms = new MemoryStream();
    serializer.WriteObject(ms, obj);
    string retVal = Encoding.UTF8.GetString(ms.ToArray());
    return retVal;
}

public static T Deserialize<T>(string json)
{
    T obj = Activator.CreateInstance<T>();
    MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(json));
    DataContractJsonSerializer serializer = new DataContractJsonSerializer(obj.GetType());
    obj = (T)serializer.ReadObject(ms);
    ms.Close();
    return obj;
}

With New-Item you can add the Force parameter

New-Item -Force -ItemType directory -Path foo

Or the ErrorAction parameter

New-Item -ErrorAction Ignore -ItemType directory -Path foo

The subquery is being run for each row because it is a correlated query. One can make a correlated query into a non-correlated query by selecting everything from the subquery, like so:

SELECT * FROM
(
    SELECT relevant_field
    FROM some_table
    GROUP BY relevant_field
    HAVING COUNT(*) > 1
) AS subquery

The final query would look like this:

SELECT *
FROM some_table
WHERE relevant_field IN
(
    SELECT * FROM
    (
        SELECT relevant_field
        FROM some_table
        GROUP BY relevant_field
        HAVING COUNT(*) > 1
    ) AS subquery
)

From your screenshot it appears you have ReSharper installed.

Depending on the key binding options you chose when you installed it, some of your standard shortcuts may now be redirected to ReSharper commands. It's worth checking, for example Ctrl+E, C is used by R# for the code cleanup dialog.

You can use the Google Collections API for that, recently renamed to Guava, specifically a BiMap

A bimap (or "bidirectional map") is a map that preserves the uniqueness of its values as well as that of its keys. This constraint enables bimaps to support an "inverse view", which is another bimap containing the same entries as this bimap but with reversed keys and values.

Close the tab of the page you disabled alerts. Re-open the page in a new tab. The setting only lasts for the session, so alerts will be re-enabled once the new session begins in the new tab.

I am surprised no one has a link for this . any format can be created using the guidelines here:

Custom Date and Time Format Strings

For your specific example (As others have indicated) use something like

my_format="yyyyMMddHHmmss";
DateTime.Now.ToString(my_format);

Where my_format can be any string combination of y,M,H,m,s,f,F and more! Check out the link.

There are several problems here:

1. The newdata argument of predict() needs a predictor variable. You should thus pass it values for Coupon, instead of Total, which is the response variable in your model.

2. The predictor variable needs to be passed in as a named column in a data frame, so that predict() knows what the numbers its been handed represent. (The need for this becomes clear when you consider more complicated models, having more than one predictor variable).

3. For this to work, your original call should pass df in through the data argument, rather than using it directly in your formula. (This way, the name of the column in newdata will be able to match the name on the RHS of the formula).

With those changes incorporated, this will work:

model <- lm(Total ~ Coupon, data=df)
new <- data.frame(Coupon = df$Coupon)
predict(model, newdata = new, interval="confidence")

Number((6.688689).toFixed(1)); // 6.7

var number = 6.688689;
var roundedNumber = Math.round(number * 10) / 10;

Use toFixed() function.

(6.688689).toFixed(); // equal to "7"
(6.688689).toFixed(1); // equal to "6.7"
(6.688689).toFixed(2); // equal to "6.69"

Just as an FYI, there is a library called breakpoints which detects the max-width as set in CSS and allows you to use it in JS if-else conditions using <=, <, >, >= and == signs. I found it quite useful. The payload size is under 3 KB.

jQuery.fn.extend({
    zigzag: function () {
        var text = $(this).text();
        var zigzagText = '';
        var toggle = true; //lower/uppper toggle
            $.each(text, function(i, nome) {
                zigzagText += (toggle) ? nome.toUpperCase() : nome.toLowerCase();
                toggle = (toggle) ? false : true;
            });
    return zigzagText;
    }
});

If you don't have Python 2.6 or higher, the alternative is to write an explicit for loop:

def set_list_intersection(set_list):
  if not set_list:
    return set()
  result = set_list[0]
  for s in set_list[1:]:
    result &= s
  return result

set_list = [set([1, 2]), set([1, 3]), set([1, 4])]
print set_list_intersection(set_list)
# Output: set([1])

You can also use reduce:

set_list = [set([1, 2]), set([1, 3]), set([1, 4])]
print reduce(lambda s1, s2: s1 & s2, set_list)
# Output: set([1])

However, many Python programmers dislike it, including Guido himself:

About 12 years ago, Python aquired lambda, reduce(), filter() and map(), courtesy of (I believe) a Lisp hacker who missed them and submitted working patches. But, despite of the PR value, I think these features should be cut from Python 3000.

So now reduce(). This is actually the one I've always hated most, because, apart from a few examples involving + or *, almost every time I see a reduce() call with a non-trivial function argument, I need to grab pen and paper to diagram what's actually being fed into that function before I understand what the reduce() is supposed to do. So in my mind, the applicability of reduce() is pretty much limited to associative operators, and in all other cases it's better to write out the accumulation loop explicitly.

In case you were struggling to change linetypes, the following answer should be helpful. (This is an addition to the solution by Andy W.)

We will try to extend the learned pattern:

cols <- c("LINE1"="#f04546","LINE2"="#3591d1","BAR"="#62c76b")
line_types <- c("LINE1"=1,"LINE2"=3)
ggplot(data=data,aes(x=a)) + 
  geom_bar(stat="identity", aes(y=h,fill = "BAR"))+ #green
  geom_line(aes(y=b,group=1, colour="LINE1", linetype="LINE1"),size=0.5) +   #red
  geom_point(aes(y=b, colour="LINE1", fill="LINE1"),size=2) +           #red
  geom_line(aes(y=c,group=1,colour="LINE2", linetype="LINE2"),size=0.5) +   #blue 
  geom_point(aes(y=c,colour="LINE2", fill="LINE2"),size=2) +           #blue
  scale_colour_manual(name="Error Bars",values=cols, 
                  guide = guide_legend(override.aes=aes(fill=NA))) + 
  scale_linetype_manual(values=line_types)+
  scale_fill_manual(name="Bar",values=cols, guide="none") +
  ylab("Symptom severity") + xlab("PHQ-9 symptoms") +
  ylim(0,1.6) +
  theme_bw() +
  theme(axis.title.x = element_text(size = 15, vjust=-.2)) +
  theme(axis.title.y = element_text(size = 15, vjust=0.3))

However, what we get is the following result:

The problem is that the linetype is not merged in the main legend. Note that we did not give any name to the method scale_linetype_manual. The trick which works here is to give it the same name as what you used for naming scale_colour_manual. More specifically, if we change the corresponding line to the following we get the desired result:

scale_linetype_manual(name="Error Bars",values=line_types)

Now, it is easy to change the size of the line with the same idea.

Note that the geom_bar has not colour property anymore. (I did not try to fix this issue.) Also, adding geom_errorbar with colour attribute spoils the result. It would be great if somebody can come up with a better solution which resolves these two issues as well.

Have a look at BranchMaster.

I wrote it to visualize complex branch structure, by collapsing all commits between them to a single line. The numbers indicates the number of commits.

To avoid some of the problems mentioned above (not robust for nulls etc etc), to get first and last element in a list an approach could be

import java.util.List;

public static final <A> A getLastElement(List<A> list) {
    return list != null ? getElement(list, list.size() - 1) : null;
}

public static final <A> A getFirstElement(List<A> list) {
    return list != null ? getElement(list, 0) : null;
}   

private static final <A> A getElement(List<A> list, int pointer) {
    A res = null;
    if (list.size() > 0) {
        res = list.get(pointer);            
    }
    return res;
}

The convention adopted is that the first/last element of an empty list is null...

     f.setLayout(null);

add the above lines ( f is a JFrame or a Container where you have added the JTestField )

But try to learn 'LayoutManager' in java ; refer to other answers for the links of the tutorials .Or try This http://docs.oracle.com/javase/tutorial/uiswing/layout/visual.html

You are mixing mysqli and mysql extensions, which will not work.

You need to use

$myConnection= mysqli_connect("$db_host","$db_username","$db_pass") or die ("could not connect to mysql"); 

mysqli_select_db($myConnection, "mrmagicadam") or die ("no database");   

mysqli has many improvements over the original mysql extension, so it is recommended that you use mysqli.

You can't update more that one table in a single statement, however the error message you get is because of the aliases, you could try this :

BEGIN TRANSACTION

update A
set A.ORG_NAME =  @ORG_NAME
from table1 A inner join table2 B
on B.ORG_ID = A.ORG_ID
and A.ORG_ID = @ORG_ID

update B
set B.REF_NAME = @REF_NAME
from table2 B inner join table1 A
    on B.ORG_ID = A.ORG_ID
    and A.ORG_ID = @ORG_ID

COMMIT

pod deintegrate

After this cmd, no traces of Cocoapods left in your project.

But your workspace referencing the Pods project still remains, you need to should remove below 3 files manually:

xx.xcworkspace
Podifle
Podfile.lock

Then you can use your project again.

Have fun!

Test CocoaPod version = 1.2.0

SOLUTION :

Set it in your viewcontroller or in rootviewcontroller by overriding the method :

-(BOOL) prefersStatusBarHidden
    {
        return YES;
    }

Put the default rowHeight in viewDidLoad or awakeFromNib. As pointed out by Martin R., you cannot call cellForRowAtIndexPath from heightForRowAtIndexPath

self.tableView.rowHeight = 44.0

Change the type to submit and give it a name (and remove the useless onclick and flat out the 90's style uppercased tags/attributes).

<input type="submit" name="foo" value="A" />
<input type="submit" name="foo" value="B" />
...

The value will be available by $_POST['foo'] (if the parent <form> has a method="post").

I highly recommend checking out Firebase's Remote Config functionality for this.

I implemented it using a parameter - app_version_enabled - with a condition "Disabled Android Versions" that looks like this:

applies if App ID == com.example.myapp and App version regular expression ^(5.6.1|5.4.2) 

Default for the parameter is "true", but Disabled Android Versions has a value of false. In my regex for Disabled Android Versions, you can add more disabled versions simply with another |{version name} inside those parentheses.

Then I just check if the configuration says the version is enabled or not -- I have an activity that I launch that forces the user to upgrade. I check in the only two places the app can be launched from externally (my default launcher activity and an intent-handling activity). Since Remote Config works on a cache basis, it won't immediately capture "disabled" versions of the app if the requisite time hasn't passed for the cache to be invalidated, but that is at most 12 hours if you're going by their recommended cache expiration value.

The easiest way is to make a "fake show" by using jquery.

element.delay(1000).fadeIn(0); // This will work

This problem may also happen if you have a unit test project that has a different C++ version than the project you want to test.

Example:

• EXE with C++ 17 enabled explicitly
• Unit Test with C++ version set to "Default"

Solution: change the Unit Test to C++17 as well.

If you need to retrieve a URL query from outside a component:

import router from 'next/router'

console.log(router.query)

    RelativeLayout layout = new RelativeLayout(this);
    RelativeLayout.LayoutParams labelLayoutParams = new RelativeLayout.LayoutParams(
            LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
    layout.setLayoutParams(labelLayoutParams);


   // If you want to add some controls in this Relative Layout
    labelLayoutParams = new RelativeLayout.LayoutParams(
            LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
    labelLayoutParams.addRule(RelativeLayout.CENTER_IN_PARENT);


    ImageView mImage = new ImageView(this);
    mImage.setBackgroundResource(R.drawable.popupnew_bg);        
    layout.addView(mImage,labelLayoutParams);

    setContentView(layout);

Haskell uses init to refer to all but the last element of a list (the inverse of tail, basically); would isInInit work, or is that too opaque?

If you would like to show it in a new window, you could use Tkinter + PIL library, like so:

import tkinter as tk
from PIL import ImageTk, Image

def show_imge(path):
    image_window = tk.Tk()
    img = ImageTk.PhotoImage(Image.open(path))
    panel = tk.Label(image_window, image=img)
    panel.pack(side="bottom", fill="both", expand="yes")
    image_window.mainloop()

This is a modified example that can be found all over the web.

There's no such thing as a global variable in C#. Period.

You can have static members if you want:

public static class MyStaticValues
{
   public static bool MyStaticBool {get;set;}
}

Ruby has two other loop/iteration control keywords: redo and retry. Read more about them, and the difference between them, at Ruby QuickTips.

In addition to given answer, it's worth noting that compiler is not required to initialize constexpr variable at compile time, knowing that the difference between constexpr and static constexpr is that to use static constexpr you ensure the variable is initialized only once.

Following code demonstrates how constexpr variable is initialized multiple times (with same value though), while static constexpr is surely initialized only once.

In addition the code compares the advantage of constexpr against const in combination with static.

#include <iostream>
#include <string>
#include <cassert>
#include <sstream>

const short const_short = 0;
constexpr short constexpr_short = 0;

// print only last 3 address value numbers
const short addr_offset = 3;

// This function will print name, value and address for given parameter
void print_properties(std::string ref_name, const short* param, short offset)
{
    // determine initial size of strings
    std::string title = "value \\ address of ";
    const size_t ref_size = ref_name.size();
    const size_t title_size = title.size();
    assert(title_size > ref_size);

    // create title (resize)
    title.append(ref_name);
    title.append(" is ");
    title.append(title_size - ref_size, ' ');

    // extract last 'offset' values from address
    std::stringstream addr;
    addr << param;
    const std::string addr_str = addr.str();
    const size_t addr_size = addr_str.size();
    assert(addr_size - offset > 0);

    // print title / ref value / address at offset
    std::cout << title << *param << " " << addr_str.substr(addr_size - offset) << std::endl;
}

// here we test initialization of const variable (runtime)
void const_value(const short counter)
{
    static short temp = const_short;
    const short const_var = ++temp;
    print_properties("const", &const_var, addr_offset);

    if (counter)
        const_value(counter - 1);
}

// here we test initialization of static variable (runtime)
void static_value(const short counter)
{
    static short temp = const_short;
    static short static_var = ++temp;
    print_properties("static", &static_var, addr_offset);

    if (counter)
        static_value(counter - 1);
}

// here we test initialization of static const variable (runtime)
void static_const_value(const short counter)
{
    static short temp = const_short;
    static const short static_var = ++temp;
    print_properties("static const", &static_var, addr_offset);

    if (counter)
        static_const_value(counter - 1);
}

// here we test initialization of constexpr variable (compile time)
void constexpr_value(const short counter)
{
    constexpr short constexpr_var = constexpr_short;
    print_properties("constexpr", &constexpr_var, addr_offset);

    if (counter)
        constexpr_value(counter - 1);
}

// here we test initialization of static constexpr variable (compile time)
void static_constexpr_value(const short counter)
{
    static constexpr short static_constexpr_var = constexpr_short;
    print_properties("static constexpr", &static_constexpr_var, addr_offset);

    if (counter)
        static_constexpr_value(counter - 1);
}

// final test call this method from main()
void test_static_const()
{
    constexpr short counter = 2;

    const_value(counter);
    std::cout << std::endl;

    static_value(counter);
    std::cout << std::endl;

    static_const_value(counter);
    std::cout << std::endl;

    constexpr_value(counter);
    std::cout << std::endl;

    static_constexpr_value(counter);
    std::cout << std::endl;
}

Possible program output:

value \ address of const is               1 564
value \ address of const is               2 3D4
value \ address of const is               3 244

value \ address of static is              1 C58
value \ address of static is              1 C58
value \ address of static is              1 C58

value \ address of static const is        1 C64
value \ address of static const is        1 C64
value \ address of static const is        1 C64

value \ address of constexpr is           0 564
value \ address of constexpr is           0 3D4
value \ address of constexpr is           0 244

value \ address of static constexpr is    0 EA0
value \ address of static constexpr is    0 EA0
value \ address of static constexpr is    0 EA0

As you can see yourself constexpr is initilized multiple times (address is not the same) while static keyword ensures that initialization is performed only once.

You are using wrong JSON. In this case you should use JSON that looks like this:

["orange", "apple"]

If you have to accept JSON in that form :

{"fruits":["apple","orange"]}

You'll have to create wrapper object:

public class FruitWrapper{

    List<String> fruits;

    //getter
    //setter
}

and then your controller method should look like this:

@RequestMapping(value = "/saveFruits", method = RequestMethod.POST, 
    consumes = "application/json")
@ResponseBody
public ResultObject saveFruits(@RequestBody FruitWrapper fruits){
...
}

My problem was inside a menu file. The compiler doesn't seem to warn you if strings which do not exist inside strings.xml are referenced in menu files. Check if your items in your menu XML files reference any strings which do not exist in your strings.xml. Usually in android:title.

TL;DR

Use one of these for universal conversion needs

//Java 7 or below
bigDecimal.setScale(0, RoundingMode.DOWN).intValueExact()
//Java 8    
bigDecimal.toBigInteger().intValueExact()

Reasoning

The answer depends on what the requirements are and how you answer these question.

• Will the BigDecimal potentially have a non-zero fractional part?
• Will the BigDecimal potentially not fit into the Integer range?
• Would you like non-zero fractional parts rounded or truncated?
• How would you like non-zero fractional parts rounded?

If you answered no to the first 2 questions, you could just use BigDecimal.intValueExact() as others have suggested and let it blow up when something unexpected happens.

If you are not absolutely 100% confident about question number 2, then intValue() is always the wrong answer.

Making it better

Let's use the following assumptions based on the other answers.

• We are okay with losing precision and truncating the value because that's what intValueExact() and auto-boxing do
• We want an exception thrown when the BigDecimal is larger than the Integer range because anything else would be crazy unless you have a very specific need for the wrap around that happens when you drop the high-order bits.

Given those params, intValueExact() throws an exception when we don't want it to if our fractional part is non-zero. On the other hand, intValue() doesn't throw an exception when it should if our BigDecimal is too large.

To get the best of both worlds, round off the BigDecimal first, then convert. This also has the benefit of giving you more control over the rounding process.

You can also, do this.

$(window).on("scroll", function () {
   if ($(this).scrollTop() > 800) {
      #code here
   } else {
      #code here
   }
});

Here is a good date and time code:

@echo off
if %date:~4,2%==01 set month=January
if %date:~4,2%==02 set month=February

if %date:~4,2%==04 set month=April
if %date:~4,2%==05 set month=May
if %date:~4,2%==06 set month=June
if %date:~4,2%==07 set month=July
if %date:~4,2%==08 set month=August
if %date:~4,2%==09 set month=September
if %date:~4,2%==10 set month=October
if %date:~4,2%==11 set month=November
if %date:~4,2%==12 set month=December

if %date:~0,3%==Mon set day=Monday
if %date:~0,3%==Tue set day=Tuesday
if %date:~0,3%==Wed set day=Wednesday
if %date:~0,3%==Thu set day=Thursday
if %date:~0,3%==Fri set day=Friday
if %date:~0,3%==Sat set day=Saturday
if %date:~0,3%==Sun set day=Sunday
echo.
echo The Date is %day%, %month% %date:~7,2%, %date:~10,4% the current time is: %time:~0,5%
pause

Outputs: The Date is Sunday, September 27, 2009 the current time is: 3:07

DIV elements can get focus if set the tabindex attribute. Here is the working example.

#focus-example > .extra {_x000D_
  display: none;_x000D_
}_x000D_
#focus-example:focus > .extra {_x000D_
  display: block;_x000D_
}

<div id="focus-example" tabindex="0">_x000D_
  <div>Focus me!</div>_x000D_
  <div class="extra">Hooray!</div>_x000D_
</div>

For more information about focus and blur, you can check out this article.

Update: And here is another example using focus to create a menu.

#toggleMenu:focus {_x000D_
  outline: none;_x000D_
}_x000D_
button:focus + .menu {_x000D_
  display: block;_x000D_
}_x000D_
.menu {_x000D_
  display: none;_x000D_
}_x000D_
.menu:focus {_x000D_
  display: none;_x000D_
}

<div id="toggleMenu" tabindex="0">_x000D_
  <button type="button">Menu</button>_x000D_
  <ul class="menu" tabindex="1">_x000D_
    <li>Home</li>_x000D_
    <li>About Me</li>_x000D_
    <li>Contacts</li>_x000D_
  </ul>_x000D_
</div>

worked for me:

AVG(CASE WHEN SecurityW <> 0 THEN SecurityW ELSE NULL END)

Even with absolute references, sort does not handle references correctly. Relative references are made to point at the same relative offset from the new row location (which is obviously wrong because other rows are not in the same relative position) and absolute references are not changed (because the SORT omits the step of translating the absolute references after each rearrangement of a row). The only way to do this is to manually MOVE the rows (having converted references to absolute) one by one. Excel then does the necessary translation of references. The Excel SORT is deficient as it does not do this.

Just in case you're using .NET 2.0 and don't have access to LINQ:

 static T First<T>(IEnumerable<T> items)
 {
     using(IEnumerator<T> iter = items.GetEnumerator())
     {
         iter.MoveNext();
         return iter.Current;
     }
 }

This should do what you're looking for...it uses generics so you to get the first item on any type IEnumerable.

Call it like so:

List<string> items = new List<string>() { "A", "B", "C", "D", "E" };
string firstItem = First<string>(items);

Or

int[] items = new int[] { 1, 2, 3, 4, 5 };
int firstItem = First<int>(items);

You could modify it readily enough to mimic .NET 3.5's IEnumerable.ElementAt() extension method:

static T ElementAt<T>(IEnumerable<T> items, int index)
{
    using(IEnumerator<T> iter = items.GetEnumerator())
    {
        for (int i = 0; i <= index; i++, iter.MoveNext()) ;
        return iter.Current;
    }
} 

Calling it like so:

int[] items = { 1, 2, 3, 4, 5 };
int elemIdx = 3;
int item = ElementAt<int>(items, elemIdx);

Of course if you do have access to LINQ, then there are plenty of good answers posted already...

I found a video which explains on how to achieve this: https://www.youtube.com/watch?v=nuw48-u3Yrg

It uses default "http" module together with "querystring" and "stringbuilder" modules. The application takes two numbers (using two textboxes) from a web page and upon submit, returns sum of those two (along with persisting the values in the textboxes). This is the best example I could find anywhere else.

Related source code:

var http = require("http");
var qs = require("querystring");
var StringBuilder = require("stringbuilder");

var port = 9000;

function getCalcHtml(req, resp, data) {

If you're using the Facebook language binding for php try this:

$driver->manage()->window()->setSize(new WebDriverDimension(1024,768));

I came up with this:

from datetime import date, timedelta

sdate = date(2008, 8, 15)   # start date
edate = date(2008, 9, 15)   # end date

delta = edate - sdate       # as timedelta

for i in range(delta.days + 1):
    day = sdate + timedelta(days=i)
    print(day)

The output:

2008-08-15
2008-08-16
...
2008-09-13
2008-09-14
2008-09-15

Your question asks for dates in-between but I believe you meant including the start and end points, so they are included. To remove the end date, delete the "+ 1" at the end of the range function. To remove the start date, insert a 1 argument to the beginning of the range function.

In Python, without external dependencies, it is something like this (untested):

with open("filename") as origin:
    for line in origin:
        if not "something" in line:
           continue
        try:
            print line.split('"')[1]
        except IndexError:
            print

This worked for me (using jQuery 2.1)

$(document).ajaxSend(function(elm, xhr, s){
    if (s.type == "POST") {
        s.data += s.data?"&":"";
        s.data += "_token=" + $('#csrf-token').val();
    }
});

or this:

$(document).ajaxSend(function(elm, xhr, s){
    if (s.type == "POST") {
        xhr.setRequestHeader('x-csrf-token', $('#csrf-token').val());
    }
});

(where #csrf-token is the element containing the token)

AlertDialog.Builder really isn't that hard to use. It's a bit intimidating at first for sure, but once you've used it a bit it's both simple and powerful. I know you've said you know how to use it, but here's just a simple example anyway:

DialogInterface.OnClickListener dialogClickListener = new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        switch (which){
        case DialogInterface.BUTTON_POSITIVE:
            //Yes button clicked
            break;

        case DialogInterface.BUTTON_NEGATIVE:
            //No button clicked
            break;
        }
    }
};

AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setMessage("Are you sure?").setPositiveButton("Yes", dialogClickListener)
    .setNegativeButton("No", dialogClickListener).show();

You can also reuse that DialogInterface.OnClickListener if you have other yes/no boxes that should do the same thing.

If you're creating the Dialog from within a View.OnClickListener, you can use view.getContext() to get the Context. Alternatively you can use yourFragmentName.getActivity().

I came across this looking for a way to format things better in an email to a co-worker. I ended up discovering that if you copy from Visual Studio Code (FREE) it retains the formatting, highlighting and everything else. This editor works with everything and has modules for every programming language I've ever encountered.

Looks beautiful in the email.

This is overly complicated, Jackson handles lists via its writer methods just as well as it handles regular objects. This should work just fine for you, assuming I have not misunderstood your question:

public void writeListToJsonArray() throws IOException {  
    final List<Event> list = new ArrayList<Event>(2);
    list.add(new Event("a1","a2"));
    list.add(new Event("b1","b2"));

    final ByteArrayOutputStream out = new ByteArrayOutputStream();
    final ObjectMapper mapper = new ObjectMapper();

    mapper.writeValue(out, list);

    final byte[] data = out.toByteArray();
    System.out.println(new String(data));
}

We can declare static methods with same signature in subclass, but it is not considered overriding as there won’t be any run-time polymorphism.Because since all static members of a class are loaded at the time of class loading so it decide at compile time(overriding at run time) Hence the answer is ‘No’.

For the "best of both worlds" you could combine S.Lott's solution with the xsendfile module: django generates the path to the file (or the file itself), but the actual file serving is handled by Apache/Lighttpd. Once you've set up mod_xsendfile, integrating with your view takes a few lines of code:

from django.utils.encoding import smart_str

response = HttpResponse(mimetype='application/force-download') # mimetype is replaced by content_type for django 1.7
response['Content-Disposition'] = 'attachment; filename=%s' % smart_str(file_name)
response['X-Sendfile'] = smart_str(path_to_file)
# It's usually a good idea to set the 'Content-Length' header too.
# You can also set any other required headers: Cache-Control, etc.
return response

Of course, this will only work if you have control over your server, or your hosting company has mod_xsendfile already set up.

EDIT:

mimetype is replaced by content_type for django 1.7

response = HttpResponse(content_type='application/force-download')  

EDIT: For nginx check this, it uses X-Accel-Redirect instead of apache X-Sendfile header.

Use $_SERVER['REQUEST_METHOD'].

I figured there's no way except going into the file system to find out if text.txt is a directory or just a file. If you wanted something simple, maybe you can just use:

s.Substring(s.LastIndexOf(@"\"));

So let's say you have a local branch foo, a remote called origin and a remote branch origin/master.

To push the contents of foo to origin/master, you first need to set its upstream:

git checkout foo
git branch -u origin/master

Then you can push to this branch using:

git push origin HEAD:master

In the last command you can add --force to replace the entire history of origin/master with that of foo.

Alan already gave you the right answer - use the sAMAccountName to filter your user.

I would add a recommendation on your use of DirectorySearcher - if you only want one or two pieces of information, add them into the "PropertiesToLoad" collection of the DirectorySearcher.

Instead of retrieving the whole big user object and then picking out one or two items, this will just return exactly those bits you need.

Sample:

adSearch.PropertiesToLoad.Add("sn");  // surname = last name
adSearch.PropertiesToLoad.Add("givenName");  // given (or first) name
adSearch.PropertiesToLoad.Add("mail");  // e-mail addresse
adSearch.PropertiesToLoad.Add("telephoneNumber");  // phone number

Those are just the usual AD/LDAP property names you need to specify.

As replace() creates/returns a new string rather than modifying the original (tt), you need to set the variable (tt) equal to the new string returned from the replace function.

tt = tt.replace(/,/g, '.')

JSFiddle

If you have a _Layout.cshtml view like this

<html>
    <body>
        @RenderBody()
        @RenderSection("scripts", required: false)
    </body>
</html>

then you can have an index.cshtml content view like this

@section scripts {
     <script type="text/javascript">alert('hello');</script>
}

the required indicates whether or not the view using the layout page must have a scripts section

I spent a while looking into this and pretty much all of the freeware and shareware on the web sucked. This included software to directly convert the .ppt file to Flash or some sort of video format and also software to record your desktop screen. Software was clunky, and the quality was poor.

The solution we eventually came up with is a little bit manual, but it gave by far the best quality results:

1. Export the .ppt file into some sort of image format (.bmp, .jpeg, .png, .tif) - it writes out one file per slide
2. Import all the slide image files into Google Picasa and use them to create a video. You can add in some nice simple transitions (it hasn't got some of the horrific .ppt one's, but who cares) and it dumps out a WMV file of your specified resolution.

Saving out as .wmv isn't perfect, but I'm sure it's probably quite straightforward to convert that to some other format or Flash. We were looking to get them up on YouTube and this did the trick.

java.util.Date date = ...
DateTime dateTime = new DateTime(date);

Make sure date isn't null, though, otherwise it acts like new DateTime() - I really don't like that.

I was having the same problem. I tried

rm -f ./.git/index.lock 

and the console gave me an error message. Then, I tried

rm --force ./.git/index.lock

and that worked.

Good Luck! This works super

I think what you have missed here is this:

https://maven.apache.org/settings.html#Servers

The repositories for download and deployment are defined by the repositories and distributionManagement elements of the POM. However, certain settings such as username and password should not be distributed along with the pom.xml. This type of information should exist on the build server in the settings.xml.

This is the prefered way of using custom repos. So probably what is happening is that the url of this repo is in settings.xml of the build server.

Once you get hold of the url and credentials, you can put them in your machine here: ~/.m2/settings.xml like this:

<settings ...> 

        .
        .
        .
        <servers>
            <server>
              <id>internal-repository-group</id>
              <username>YOUR-USERNAME-HERE</username>
              <password>YOUR-PASSWORD-HERE</password>
            </server>
        </servers>
</settings>

EDIT:

You then need to refer this repository into project POM. The id internal-repository-group can be used in every project. You can setup multiple repos and credentials setting using different IDs in settings xml.

The advantage of this approach is that project can be shared without worrying about the credentials and don't have to mention the credentials in every project.

Following is a sample pom of a project using "internal-repository-group"

<repositories>
    <repository>
        <id>internal-repository-group</id>
        <name>repo-name</name>
        <url>http://project.com/yourrepourl/</url>
        <layout>default</layout>
        <releases>
            <enabled>true</enabled>
            <updatePolicy>never</updatePolicy>
        </releases>
        <snapshots>
            <enabled>true</enabled>
            <updatePolicy>never</updatePolicy>
        </snapshots>
    </repository>

The only way you can read a variable amount of data from stdin is using loops. I've always found that the std::getline() function works very well:

std::string line;
while (std::getline(std::cin, line))
{
    std::cout << line << std::endl;
}

By default getline() reads until a newline. You can specify an alternative termination character, but EOF is not itself a character so you cannot simply make one call to getline().

Look at the following example, from the HTML5 specification about aside.

It makes clear that what currently is recommended (October 2012) it is to group widgets inside aside elements. Then, each widget is whatever best represents it, a nav, a serie of blockquotes, etc

The following extract shows how aside can be used for blogrolls and other side content on a blog:

<body>

I had the problem of date picker mixed with month picker. I solved it like that.

    $('.monthpicker').focus(function()
    {
    $(".ui-datepicker-calendar").show();
    }).datepicker( {
        changeMonth: true,
        changeYear: true,
        showButtonPanel: true,
        dateFormat: 'MM/yy',
        create: function (input, inst) { 

         },
        onClose: function(dateText, inst) { 
            var month = 1+parseInt($("#ui-datepicker-div .ui-datepicker-month :selected").val());           
            var year = $("#ui-datepicker-div .ui-datepicker-year :selected").val();

        }
    });

Try doing this:

• Unplug the device
• Execute adb kill-server && adb start-server(that restarts adb)
• Re-plug the device

Also you can try to edit an adb config file .android/adb_usb.ini and add a line 04e8 after the header. Restart adb required for changes to take effect.

You might want to use Scanner to parse through and find the specific sections you want to modify. There's also Split and StringTokenizer that may work, but at the level you're working at Scanner might be what's needed.

Here's some additional info on what the difference is between them: Scanner vs. StringTokenizer vs. String.Split

NSString * formattedname;
NSString * firstname;
NSString * middlename;
NSString * lastname;

firstname = @"My First Name";
middlename = @"My Middle Name";
lastname = @"My Last Name";

formattedname = [NSString stringWithFormat:@"My Full Name: %@ %@ %@", firstname, middlename, lastname];
NSLog(@"\n\nHere is the Formatted Name:\n%@\n\n", formattedname);

/*
Result:
Here is the Formatted Name:
My Full Name: My First Name My Middle Name My Last Name
*/

In react native, I had the error not show maps and close app, run adb logcat and show error within console:

java.lang.NoClassDefFoundError:failed resolution of :Lorg/apache/http/ProtocolVersion

fix it by adding within androidManifest.xml

<uses-library
  android:name="org.apache.http.legacy"
  android:required="false" />

Using Linq to xml

Add a reference to System.Xml.Linq

and use

XDocument.Parse(string xmlString)

Edit: Sample follows, xml data (TestConfig.xml)..

<?xml version="1.0"?>
<Tests>
  <Test TestId="0001" TestType="CMD">
    <Name>Convert number to string</Name>
    <CommandLine>Examp1.EXE</CommandLine>
    <Input>1</Input>
    <Output>One</Output>
  </Test>
  <Test TestId="0002" TestType="CMD">
    <Name>Find succeeding characters</Name>
    <CommandLine>Examp2.EXE</CommandLine>
    <Input>abc</Input>
    <Output>def</Output>
  </Test>
  <Test TestId="0003" TestType="GUI">
    <Name>Convert multiple numbers to strings</Name>
    <CommandLine>Examp2.EXE /Verbose</CommandLine>
    <Input>123</Input>
    <Output>One Two Three</Output>
  </Test>
  <Test TestId="0004" TestType="GUI">
    <Name>Find correlated key</Name>
    <CommandLine>Examp3.EXE</CommandLine>
    <Input>a1</Input>
    <Output>b1</Output>
  </Test>
  <Test TestId="0005" TestType="GUI">
    <Name>Count characters</Name>
    <CommandLine>FinalExamp.EXE</CommandLine>
    <Input>This is a test</Input>
    <Output>14</Output>
  </Test>
  <Test TestId="0006" TestType="GUI">
    <Name>Another Test</Name>
    <CommandLine>Examp2.EXE</CommandLine>
    <Input>Test Input</Input>
    <Output>10</Output>
  </Test>
</Tests>

C# usage...

XElement root = XElement.Load("TestConfig.xml");
IEnumerable<XElement> tests =
    from el in root.Elements("Test")
    where (string)el.Element("CommandLine") == "Examp2.EXE"
    select el;
foreach (XElement el in tests)
    Console.WriteLine((string)el.Attribute("TestId"));

This code produces the following output: 0002 0006

I often have this problem with sequences (as opposed to discrete values). If I have a sequence of ints, and I want to SUM them, when the list is empty I'll receive the error "InvalidOperationException: The null value cannot be assigned to a member with type System.Int32 which is a non-nullable value type.".

I find I can solve this by casting the sequence to a nullable type. SUM and the other aggregate operators don't throw this error if a sequence of nullable types is empty.

So for example something like this

MySum = MyTable.Where(x => x.SomeCondtion).Sum(x => x.AnIntegerValue);

becomes

MySum = MyTable.Where(x => x.SomeCondtion).Sum(x => (int?) x.AnIntegerValue);

The second one will return 0 when no rows match the where clause. (the first one throws an exception when no rows match).

You can use a different overload of Replace() that takes string.

val = val.Replace("-", string.Empty)

select to_timestamp(cast(epoch_ms/1000 as bigint))::date

worked for me

Nice ... very nice We can also replace all array values like this

Array.prototype.ReplaceAllValues = function(OldValue,newValue)
{
    for( var i = 0; i < this.length; i++ )  
    {
        if( this[i] == OldValue )       
        {
            this[i] = newValue;
        }
    }
};

You have to go through each character in the String and check Character.isDigit(char); or Character.isletter(char);

Alternatively, you can use regex.

This error is encountered when the primary key of a table is updated but it is referenced by a foreign key from another table and the update specific is set to No action. The No action is the default option.

If this is your case and No action is set on the update operation you can change the foreign-key definition to Cascade.

Right click your foreign key and select Modify. In the Foreign key relationships dialog under the INSERT and UPDATE specifics set the UPDATE rule on Cascade:

You can also set the rule using T-SQL:

ALTER TABLE YourTable
DROP Constraint Your_FK
GO

ALTER TABLE YourTable
ADD CONSTRAINT [New_FK_Constraint]
FOREIGN KEY (YourColumn) REFERENCES ReferencedTable(YourColumn)
ON DELETE CASCADE ON UPDATE CASCADE
GO 

Hope this helps

I will start my answer saying that most of previous answers were perfectly good answers at the time of writing them. So, thank you to them who wrote them.

Now, you can also use String Interpolation for same solution.

Edit: Adding this explanation after receiving a perfectively valid constructive comment from Heretic Monkey. I have preferred to use .ToString whenever I had need to convert an integer to string and not add the result to any other string. And, I have preferred to use interpolation whenever I had need to combine string(s) and an integer, like in below examples.

String Interpolation

i.ToString("00")
01

i.ToString("000")
001

i.ToString("0000")
0001

$"Prefix_{i:00}"
Prefix_01

$"Prefix_{i:000}"
Prefix_001

$"Prefix_{i:0000}_Suffix"
Prefix_0001_Suffix

git show <revhash>

Documentation here. Or if that doesn't work, try Google Code's GIT Documentation

Use the not boolean operator:

nyval = not myval

not returns a boolean value (True or False):

>>> not 1
False
>>> not 0
True

If you must have an integer, cast it back:

nyval = int(not myval)

However, the python bool type is a subclass of int, so this may not be needed:

>>> int(not 0)
1
>>> int(not 1)
0
>>> not 0 == 1
True
>>> not 1 == 0
True

I don't think that solution would work anyways because you will see some error message in your error log file.

The solution was a lot easier than what I thought.

simply, open the following path to your php5-fpm

sudo nano /etc/php5/fpm/pool.d/www.conf

or if you're the admin 'root'

nano /etc/php5/fpm/pool.d/www.conf

Then find this line and uncomment it:

listen.allowed_clients = 127.0.0.1

This solution will make you be able to use listen = 127.0.0.1:9000 in your vhost blocks

like this: fastcgi_pass 127.0.0.1:9000;

after you make the modifications, all you need is to restart or reload both Nginx and Php5-fpm

Php5-fpm

sudo service php5-fpm restart

or

sudo service php5-fpm reload

Nginx

sudo service nginx restart

or

sudo service nginx reload

From the comments:

Also comment

;listen = /var/run/php5-fpm.sock 

and add

listen = 9000

Look in your settings.xml (or, possibly your project's parent or corporate parent POM) for the <repositories> element. It will look something like the below.

<repositories>
    <repository>
        <id>central</id>
        <url>http://gotoNexus</url>
        <snapshots>
            <enabled>true</enabled>
            <updatePolicy>always</updatePolicy>
        </snapshots>
        <releases>
            <enabled>true</enabled>
            <updatePolicy>daily</updatePolicy>
        </releases>
    </repository>
</repositories>

Note the <updatePolicy> element. The example tells Maven to contact the remote repo (Nexus in my case, Maven Central if you're not using your own remote repo) any time Maven needs to retrieve a snapshot artifact during a build, checking to see if there's a newer copy. The metadata is required for this. If there is a newer copy Maven downloads it to your local repo.

In the example, for releases, the policy is daily so it will check during your first build of the day. never is also a valid option, as described in Maven settings docs.

Plugins are resolved separately. You may have repositories configured for those as well, with different update policies if desired.

<pluginRepositories>
    <pluginRepository>
        <id>central</id>
        <url>http://gotoNexus</url>
        <snapshots>
            <enabled>true</enabled>
            <updatePolicy>daily</updatePolicy>
        </snapshots>
        <releases>
            <enabled>true</enabled>
            <updatePolicy>never</updatePolicy>
        </releases>
    </pluginRepository>
</pluginRepositories>

Someone else mentioned the -o option. If you use that, Maven runs in "offline" mode. It knows it has a local repo only, and it won't contact the remote repo to refresh the artifacts no matter what update policies you use.

go
sp_configure 'show advanced options',1  
reconfigure with override  
go  
sp_configure 'Ad Hoc Distributed Queries',1  
reconfigure with override  
go
SELECT * into temptable

                'SELECT * FROM [Sheet1$]')

My alternative solution to using Valgrind:

I'm very happy because I just helped my friend debug a program. His program had this exact problem (malloc() causing abort), with the same error message from GDB.

I compiled his program using Address Sanitizer with

gcc -Wall -g3 -fsanitize=address -o new new.c
              ^^^^^^^^^^^^^^^^^^

And then ran gdb new. When the program gets terminated by SIGABRT caused in a subsequent malloc(), a whole lot of useful information is printed:

=================================================================
==407==ERROR: AddressSanitizer: heap-buffer-overflow on address 0x6060000000b4 at pc 0x7ffffe49ed1a bp 0x7ffffffedc20 sp 0x7ffffffed3c8

    #3 0x7ffffe061b96 in __libc_start_main (/lib/x86_64-linux-gnu/libc.so.6+0x21b96)

Let's take a look at the output, especially the stack trace:

The first part says there's a invalid write operation at new.c:59. That line reads

memset(len,0,sizeof(int*)*p);
             ^^^^^^^^^^^^

The second part says the memory that the bad write happened on is created at new.c:55. That line reads

if(!(len=(int*)malloc(sizeof(int)*p))){
                      ^^^^^^^^^^^

That's it. It only took me less than half a minute to locate the bug that confused my friend for a few hours. He managed to locate the failure, but it's a subsequent malloc() call that failed, without being able to spot this error in previous code.

Sum up: Try the -fsanitize=address of GCC or Clang. It can be very helpful when debugging memory issues.

Bash 3 solution:

In reading some of the answers I put together a quick little function I would like to contribute back that might help others.

# Define a hash like this
MYHASH=("firstName:Milan"
        "lastName:Adamovsky")

# Function to get value by key
getHashKey()
 {
  declare -a hash=("${!1}")
  local key
  local lookup=$2

  for key in "${hash[@]}" ; do
   KEY=${key%%:*}
   VALUE=${key#*:}
   if [[ $KEY == $lookup ]]
   then
    echo $VALUE
   fi
  done
 }

# Function to get a list of all keys
getHashKeys()
 {
  declare -a hash=("${!1}")
  local KEY
  local VALUE
  local key
  local lookup=$2

  for key in "${hash[@]}" ; do
   KEY=${key%%:*}
   VALUE=${key#*:}
   keys+="${KEY} "
  done

  echo $keys
 }

# Here we want to get the value of 'lastName'
echo $(getHashKey MYHASH[@] "lastName")


# Here we want to get all keys
echo $(getHashKeys MYHASH[@])

word-wrap property work's with display:inline-block:

display: inline-block;
word-wrap: break-word;
width: 100px;

An alternative solution for preventing functions to change the user par. You can set the default parameters early on the function, so that the graphical parameters and layout will not be changed during the function execution. See ?on.exit for further details.

on.exit(layout(1))
opar<-par(no.readonly=TRUE)
on.exit(par(opar),add=TRUE,after=FALSE)

Given some C/C++ file foo.c:

> clang -S -emit-llvm foo.c

Produces foo.ll which is an LLVM IR file.

The -emit-llvm option can also be passed to the compiler front-end directly, and not the driver by means of -cc1:

> clang -cc1 foo.c -emit-llvm

Produces foo.ll with the IR. -cc1 adds some cool options like -ast-print. Check out -cc1 --help for more details.

To compile LLVM IR further to assembly, use the llc tool:

> llc foo.ll

Produces foo.s with assembly (defaulting to the machine architecture you run it on). llc is one of the LLVM tools - here is its documentation.

Seems the most foolproof way to start with a UTC date is to create a new Date object and use the setUTC… methods to set it to the date/time you want.

Then the various toLocale…String methods will provide localized output.

Example:

// This would come from the server._x000D_
// Also, this whole block could probably be made into an mktime function._x000D_
// All very bare here for quick grasping._x000D_
d = new Date();_x000D_
d.setUTCFullYear(2004);_x000D_
d.setUTCMonth(1);_x000D_
d.setUTCDate(29);_x000D_
d.setUTCHours(2);_x000D_
d.setUTCMinutes(45);_x000D_
d.setUTCSeconds(26);_x000D_
_x000D_
console.log(d);                        // -> Sat Feb 28 2004 23:45:26 GMT-0300 (BRT)_x000D_
console.log(d.toLocaleString());       // -> Sat Feb 28 23:45:26 2004_x000D_
console.log(d.toLocaleDateString());   // -> 02/28/2004_x000D_
console.log(d.toLocaleTimeString());   // -> 23:45:26

Some references:

• toLocaleString
• toLocaleDateString
• toLocaleTimeString
• getTimezoneOffset

pip list is a shell command. You should run it in your shell (bash/cmd), rather than invoke it from python interpreter.

pip does not provide a stable API. The only supported way of calling it is via subprocess, see docs and the code at the end of this answer.

However, if you want to just check if pip exists locally, without running it, and you are running Linux, I would suggest that you use bash's which command:

which pip

It should show you whether the command can be found in bash's PATH/aliases, and if it does, what does it actually execute.

If running pip is not an issue, you could just do:

python -m pip --version

If you really need to do it from a python script, you can always put the import statement into a try...except block:

try:
    import pip
except ImportError:
    print("Pip not present.")

Or check what's the output of a pip --version using subprocess module:

subprocess.check_call([sys.executable, '-m', 'pip', '--version'])

A better way would be to create a Map to store your count. That would be a Map<Character, Integer>

You need iterate over each character of your string, and check whether its an alphabet. You can use Character#isAlphabetic method for that. If it is an alphabet, increase its count in the Map. If the character is not already in the Map then add it with a count of 1.

NOTE: - Character.isAlphabetic method is new in Java 7. If you are using an older version, you should use Character#isLetter

    String str = "asdfasdfafk asd234asda";
    Map<Character, Integer> charMap = new HashMap<Character, Integer>();
    char[] arr = str.toCharArray();

    for (char value: arr) {

       if (Character.isAlphabetic(value)) {
           if (charMap.containsKey(value)) {
               charMap.put(value, charMap.get(value) + 1);

           } else {
               charMap.put(value, 1);
           }
       }
    }

    System.out.println(charMap);

OUTPUT: -

{f=3, d=4, s=4, a=6, k=1}

My idea of that program is that:

package text;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class CoutingWords {

    public static void main(String[] args) throws IOException {
        String str;
        int cWords = 1;
        char ch;

        BufferedReader buffor = new BufferedReader(new InputStreamReader(System.in));

        System.out.println("Enter text: ");
        str = buffor.readLine();

        for(int i =0; i<str.length(); i++){
            ch = str.charAt(i);
            if(Character.isWhitespace(ch)){ cWords++; }
        }
        System.out.println("There are " + (int)cWords +" words.");
    }
}

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

How about unicode-escape?

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

Use this

DefaultHttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet("http://www.someplace.com");
ResponseHandler<String> resHandler = new BasicResponseHandler();
String page = httpClient.execute(httpGet, resHandler);

This can be used to grab the whole webpage as a string of html, i.e., "<html>...</html>"

Based on the solution by Jason Bunting, here is what I use now.

The whole thing is for the jQuery tablesorter plug-in: For (nearly correct) sorting of non-English tables with tablesorter plugin it is necessary to make use of a custom textExtraction function.

This one:

• translates the most common accented letters to unaccented ones (the list of supported letters is easily expandable)
• changes dates in German format ('dd.mm.yyyy') to a recognized format ('yyyy-mm-dd')

Be careful to save the JavaScript file in UTF-8 encoding or it won't work.

// file encoding must be UTF-8!
function getTextExtractor()
{
  return (function() {
    var patternLetters = /[öäüÖÄÜáàâéèêúùûóòôÁÀÂÉÈÊÚÙÛÓÒÔß]/g;
    var patternDateDmy = /^(?:\D+)?(\d{1,2})\.(\d{1,2})\.(\d{2,4})$/;
    var lookupLetters = {
      "ä": "a", "ö": "o", "ü": "u",
      "Ä": "A", "Ö": "O", "Ü": "U",
      "á": "a", "à": "a", "â": "a",
      "é": "e", "è": "e", "ê": "e",
      "ú": "u", "ù": "u", "û": "u",
      "ó": "o", "ò": "o", "ô": "o",
      "Á": "A", "À": "A", "Â": "A",
      "É": "E", "È": "E", "Ê": "E",
      "Ú": "U", "Ù": "U", "Û": "U",
      "Ó": "O", "Ò": "O", "Ô": "O",
      "ß": "s"
    };
    var letterTranslator = function(match) { 
      return lookupLetters[match] || match;
    }

    return function(node) {
      var text = $.trim($(node).text());
      var date = text.match(patternDateDmy);
      if (date)
        return [date[3], date[2], date[1]].join("-");
      else
        return text.replace(patternLetters, letterTranslator);
    }
  })();
}

You can use it like this:

$("table.sortable").tablesorter({ 
  textExtraction: getTextExtractor()
}); 

http://docs.mongodb.org/manual/tutorial/create-an-auto-incrementing-field/

You can also check this link and auto-increment the _id field.

Try it like this:

Sub testIt()
Dim r As Long, endRow as Long, pasteRowIndex As Long

endRow = 10 ' of course it's best to retrieve the last used row number via a function
pasteRowIndex = 1

For r = 1 To endRow 'Loop through sheet1 and search for your criteria

    If Cells(r, Columns("B").Column).Value = "YourCriteria" Then 'Found

            'Copy the current row
            Rows(r).Select 
            Selection.Copy

            'Switch to the sheet where you want to paste it & paste
            Sheets("Sheet2").Select
            Rows(pasteRowIndex).Select
            ActiveSheet.Paste

            'Next time you find a match, it will be pasted in a new row
            pasteRowIndex = pasteRowIndex + 1


           'Switch back to your table & continue to search for your criteria
            Sheets("Sheet1").Select  
    End If
Next r
End Sub

Why don't you simply use set_index method?

In : col = ['a','b','c']

In : data = DataFrame([[1,2,3],[10,11,12],[20,21,22]],columns=col)

In : data
Out:
    a   b   c
0   1   2   3
1  10  11  12
2  20  21  22

In : data2 = data.set_index('a')

In : data2
Out:
     b   c
a
1    2   3
10  11  12
20  21  22

You have to use show() methode when you done all initialisations in your code in order to see the complet version of plot:

import matplotlib.pyplot as plt

plt.plot(x, y)
................
................
plot.show()

100% avoidance of reverse engineering of the Android APK is not possible, but you can use these ways to avoid extracting more data, like source code, assets form your APK, and resources:

1. Use ProGuard to obfuscate application code

2. Use NDK using C and C++ to put your application core and secure part of code in .so files

3. To secure resources, don't include all important resources in the assets folder with APK. Download these resources at the time of application first start up.

For a new project select the home directory of the jdk

eg C:\Java\jdk1.7.0_99 or C:\Program Files\Java\jdk1.7.0_99

For an existing project.

1) You need to have a jdk installed on the system.

for instance in

C:\Java\jdk1.7.0_99

2) go to project structure under File menu ctrl+alt+shift+S

3) SDKs is located under Platform Settings. Select it.

4) click the green + up the top of the window.

5) select JDK (I have to use keyboard to select it do not know why).

select the home directory for your jdk installation.

should be good to go.

Beginning with C# 7.1, you can use default literal to produce the default value of a type when the compiler can infer the expression type.

Console.Writeline(default(Guid));  
   // ouptut: 00000000-0000-0000-0000-000000000000

Console.WriteLine(default(int));  // output: 0

Console.WriteLine(default(object) is null);  // output: True

https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/operators/default

It is.

test.hpp:

class A {
public:
    static int a(int i);
};

test.cpp:

#include <iostream>
#include "test.hpp"


int A::a(int i) {
    return i + 2;
}

using namespace std;
int main() {
    cout << A::a(4) << endl;
}

They're not always inline, no, but the compiler can make them.

I ran into this problem and was solved by checking the min sdk version in the manifest. It was set to 15 (ICS), but my phone was running 10(Gingerbread)

SELECT *
FROM  yourtable
where DATE_FORMAT(date_created, '%Y-%m') = date_format(DATE_SUB(curdate(), INTERVAL 1 month),'%Y-%m')

This should return all the records from the previous calendar month, as opposed to the records for the last 30 or 31 days.

Here's how I would do it. I'll leave range checking on the int month up to you.

import java.text.DateFormatSymbols;

public String formatMonth(int month, Locale locale) {
    DateFormatSymbols symbols = new DateFormatSymbols(locale);
    String[] monthNames = symbols.getMonths();
    return monthNames[month - 1];
}

2019 Answer (for Windows):

If you want a permanent UUID that identifies a machine uniquely on Windows, you can use this trick: (Copied from my answer at https://stackoverflow.com/a/58416992/8874388).

from typing import Optional
import re
import subprocess
import uuid

def get_windows_uuid() -> Optional[uuid.UUID]:
    try:
        # Ask Windows for the device's permanent UUID. Throws if command missing/fails.
        txt = subprocess.check_output("wmic csproduct get uuid").decode()

        # Attempt to extract the UUID from the command's result.
        match = re.search(r"\bUUID\b[\s\r\n]+([^\s\r\n]+)", txt)
        if match is not None:
            txt = match.group(1)
            if txt is not None:
                # Remove the surrounding whitespace (newlines, space, etc)
                # and useless dashes etc, by only keeping hex (0-9 A-F) chars.
                txt = re.sub(r"[^0-9A-Fa-f]+", "", txt)

                # Ensure we have exactly 32 characters (16 bytes).
                if len(txt) == 32:
                    return uuid.UUID(txt)
    except:
        pass # Silence subprocess exception.

    return None

print(get_windows_uuid())

Uses Windows API to get the computer's permanent UUID, then processes the string to ensure it's a valid UUID, and lastly returns a Python object (https://docs.python.org/3/library/uuid.html) which gives you convenient ways to use the data (such as 128-bit integer, hex string, etc).

Good luck!

PS: The subprocess call could probably be replaced with ctypes directly calling Windows kernel/DLLs. But for my purposes this function is all I need. It does strong validation and produces correct results.

SELECT *
  FROM (SELECT * FROM MyTbl ORDER BY Fname )
 WHERE ROWNUM = 1;

It might be appropriate to catch error within unit tests that check an assertion is made. If someone disables assertions or otherwise deletes the assertion you would want to know

As ephemient said, the C library libc is linked by default and this library contains the implementations of stdlib.h, stdio.h and several other standard header files. Just to add to it, according to "An Introduction to GCC" the linker command for a basic "Hello World" program in C is as below:

ld -dynamic-linker /lib/ld-linux.so.2 /usr/lib/crt1.o 
/usr/lib/crti.o /usr/libgcc-lib /i686/3.3.1/crtbegin.o
-L/usr/lib/gcc-lib/i686/3.3.1 hello.o -lgcc -lgcc_eh -lc 
-lgcc -lgcc_eh /usr/lib/gcc-lib/i686/3.3.1/crtend.o /usr/lib/crtn.o

Notice the option -lc in the third line that links the C library.

Add following @IBInspectables in UIView extension

extension UIView {

  @IBInspectable var borderWidth: CGFloat {
    get {
      return layer.borderWidth
    }
    set(newValue) {
      layer.borderWidth = newValue
    }
  }

  @IBInspectable var borderColor: UIColor? {
    get {
      if let color = layer.borderColor {
        return UIColor(CGColor: color)
      }
      return nil
    }
    set(newValue) {
      layer.borderColor = newValue?.CGColor
    }
  }
}

And then you should be able to set borderColor and borderWidth attributes directly from Attribute inspector. See attached image

I'm no Git master, but from searching around the solution that worked easiest for me was to just go to C:\Program Files (x86)\Git\etc and open profile in a text editor.

There's an if statement on line 37 # Set up USER's home directory. I took out the if statement and put in the local directory that I wanted the gitconfig to be, then I just copied my existing gitconfig file (was on a network drive) to that location.

(Not an answer, but a very similar problem) I have Git Gui installed on a Windows system behind a proxy. Issuing 'git clone' from a Linux virtual machine running on the Windows system works, but Git Gui yields the 443 error mentioned in the heading.

To fix this, one must edit %USERPROFILE%\.gitconfig to add an [http] section:

[http]
    postBuffer = 1000000000
    proxy = the.proxy.address:the.proxy.port
    sslcainfo = C:/Users/username/Documents/the.certificate.name.cer

Note that the path to the security certificate file has had its backslashes ('\') replaced by slashes ('/').

The error you are getting is in line 3. i.e. it is not in

CONSTRAINT no_duplicate_tag UNIQUE (question_id, tag_id)

but earlier:

CREATE TABLE tags
     (
              (question_id, tag_id) NOT NULL,

Correct table definition is like pilcrow showed.

And if you want to add unique on tag1, tag2, tag3 (which sounds very suspicious), then the syntax is:

CREATE TABLE tags (
    question_id INTEGER NOT NULL,
    tag_id SERIAL NOT NULL,
    tag1 VARCHAR(20),
    tag2 VARCHAR(20),
    tag3 VARCHAR(20),
    PRIMARY KEY(question_id, tag_id),
    UNIQUE (tag1, tag2, tag3)
);

or, if you want to have the constraint named according to your wish:

CREATE TABLE tags (
    question_id INTEGER NOT NULL,
    tag_id SERIAL NOT NULL,
    tag1 VARCHAR(20),
    tag2 VARCHAR(20),
    tag3 VARCHAR(20),
    PRIMARY KEY(question_id, tag_id),
    CONSTRAINT some_name UNIQUE (tag1, tag2, tag3)
);

select 
  Ml.Hid,
  ml.blockid,
  row_number() over (partition by ml.blockid order by Ml.Hid desc) as rownumber,

join [MT.HAMLE] h on ML.Hid=h.HID

I had a similar problem and since I couldn't find a sufficient solution, I also created a serialization library for javascript: https://github.com/wavesoft/jbb (as a matter of fact it's a bit more, since it's mainly intended for bundling resources)

It is close to Binary-JSON but it adds a couple of additional features, such as metadata for the objects being encoded and some extra optimizations like data de-duplication, cross-referencing to other bundles and structure-level compression.

However there is a catch: In order to keep the bundle size small there are no type information in the bundle. Such information are provided in a separate "profile" that describes your objects for encoding and decoding. For optimization reasons this information is given in a form of script.

But you can make your life easier using the gulp-jbb-profile (https://github.com/wavesoft/gulp-jbb-profile) utility for generating the encodeing/decoding scripts from simple YAML object specifications like this:

# The 'Person' object has the 'age' and 'isOld'
# properties
Person:
  properties:
    - age
    - isOld

For example you can have a look on the jbb-profile-three profile. When you have your profile ready, you can use JBB like this:

var JBBEncoder = require('jbb/encode');
var MyEncodeProfile = require('profile/profile-encode');

// Create a new bundle
var bundle = new JBBEncoder( 'path/to/bundle.jbb' );

// Add one or more profile(s) in order for JBB
// to understand your custom objects
bundle.addProfile(MyEncodeProfile);

// Encode your object(s) - They can be any valid
// javascript object, or objects described in
// the profiles you added previously.

var p1 = new Person(77);
bundle.encode( p1, 'person' );

var people = [
        new Person(45),
        new Person(77),
        ...
    ];
bundle.encode( people, 'people' );

// Close the bundle when you are done
bundle.close();

And you can read it back like this:

var JBBDecoder = require('jbb/decode');
var MyDecodeProfile = require('profile/profile-decode');

// Instantiate a new binary decoder
var binaryLoader = new JBBDecoder( 'path/to/bundle' );

// Add your decoding profile
binaryLoader.addProfile( MyDecodeProfile );

// Add one or more bundles to load
binaryLoader.add( 'bundle.jbb' );

// Load and callback when ready
binaryLoader.load(function( error, database ) {

    // Your objects are in the database
    // and ready to use!
    var people = database['people'];

});

A little mathematical logic theory here:

"NOT a AND NOT b" is the same as "NOT (a OR b)", so:

"a NOT -1 AND b NOT -1" is equivalent of "NOT (a is -1 OR b is -1)", which is opposite (Complement) of "(a is -1 OR b is -1)".

So if you want exact opposite result, df1 and df2 should be as below:

df1 = df[(df.a != -1) & (df.b != -1)]
df2 = df[(df.a == -1) | (df.b == -1)]

Furthermore to Jon's answer if you use static final it will behave as a kind-of "definition". Once you compile the class which uses it, it will be in the compiled .class file burnt. Check my thread about it here.

For your main goal: If you don't use the NUMBER differently in the different instances of the class i would advise to use final and static. (You just have to keep in mind to not to copy compiled class files without considering possible troubles like the one my case study describes. Most of the cases this does not occur, don't worry :) )

To show you how to use different values in instances check this code:

public class JustFinalAttr {
  public final int Number;

  public JustFinalAttr(int a){
    Number=a;
  }
}

...System.out.println(new JustFinalAttr(4).Number);

As of 2016, you can do this more simply than in any of the answers already given:

$('#myChosenBox').val();

where "myChosenBox" is the id of the original select input. Or, in the change event:

$('#myChosenBox').on('change', function(e, params) {
    alert(e.target.value); // OR
    alert(this.value); // OR
    alert(params.selected); // also in Panagiotis Kousaris' answer
}

In the Chosen doc, in the section near the bottom of the page on triggering events, it says "Chosen triggers a number of standard and custom events on the original select field." One of those standard events is the change event, so you can use it in the same way as you would with a standard select input. You don't have to mess around with using Chosen's applied classes as selectors if you don't want to. (For the change event, that is. Other events are often a different matter.)

For at DataFrame one can simply type

head(data, num=10L)

to get the first 10 for example.

For a data.frame one can simply type

head(data, 10)

to get the first 10.

Your CSS is actually setting the rest of the document to not show overflow therefore the document itself isn't scrolling. The easiest fix for this is bind the event to the thing that is scrolling, which in your case is div#page.

So its easy as changing:

$(document).scroll(function() {  // OR  $(window).scroll(function() {
    didScroll = true;
});

to

$('div#page').scroll(function() {
    didScroll = true;
});

I'm assuming I can answer my own question.... This worked for me.

1. File -> Invalidate caches / Restart
2. Shutdown Android Studio
3. Rename/remove .gradle folder in the user home directory
4. Restart Android Studio let it download all the Gradle stuff it needs
5. Gradle build success !
6. Rebuild project.... success !

Out of curiousity I compared the structure of the old .gradle and the new one... they were pretty different !

So I'll see how 0.4.2 goes :)

I'm using tesseract OCR engine with TessNet2 (a C# wrapper - http://www.pixel-technology.com/freeware/tessnet2/).

Some basic code:

using tessnet2;

...

Bitmap image = new Bitmap(@"u:\user files\bwalker\2849257.tif");
            tessnet2.Tesseract ocr = new tessnet2.Tesseract();
            ocr.SetVariable("tessedit_char_whitelist", "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz.,$-/#&=()\"':?"); // Accepted characters
            ocr.Init(@"C:\Users\bwalker\Documents\Visual Studio 2010\Projects\tessnetWinForms\tessnetWinForms\bin\Release\", "eng", false); // Directory of your tessdata folder
            List<tessnet2.Word> result = ocr.DoOCR(image, System.Drawing.Rectangle.Empty);
            string Results = "";
            foreach (tessnet2.Word word in result)
            {
                Results += word.Confidence + ", " + word.Text + ", " + word.Left + ", " + word.Top + ", " + word.Bottom + ", " + word.Right + "\n";
            }

In your app.config, change your appsetting to:

<applicationSettings>
    <WpfApplication1.Properties.Settings>
        <setting name="appsetting" serializeAs="String">
            <value>c:\testdata.xml</value>
        </setting>
    </WpfApplication1.Properties.Settings>
</applicationSettings>

Then, in the code-behind:

string xmlDataDirectory = WpfApplication1.Properties.Settings.Default.appsetting.ToString()

You can use Notification and NotificationManager to display the notification you want. You can then customize the sound you want to play with your notification.

And if push --force doesn't work you can do push --delete. Look at 2^nd line on this instance:

git reset --hard HEAD~3  # reset current branch to 3 commits ago
git push origin master --delete  # do a very very bad bad thing
git push origin master  # regular push

But beware...

Never ever go back on a public git history!

In other words:

• Don't ever force push on a public repository.
• Don't do this or anything that can break someone's pull.
• Don't ever reset or rewrite history in a repo someone might have already pulled.

Of course there are exceptionally rare exceptions even to this rule, but in most cases it's not needed to do it and it will generate problems to everyone else.

Do a revert instead.

And always be careful with what you push to a public repo. Reverting:

git revert -n HEAD~3..HEAD  # prepare a new commit reverting last 3 commits
git commit -m "sorry - revert last 3 commits because I was not careful"
git push origin master  # regular push

In effect, both origin HEADs (from the revert and from the evil reset) will contain the same files.

edit to add updated info and more arguments around push --force

Consider pushing force with lease instead of push, but still prefer revert

Another problem push --force may bring is when someone push anything before you do, but after you've already fetched. If you push force your rebased version now you will replace work from others.

git push --force-with-lease introduced in the git 1.8.5 (thanks to @VonC comment on the question) tries to address this specific issue. Basically, it will bring an error and not push if the remote was modified since your latest fetch.

This is good if you're really sure a push --force is needed, but still want to prevent more problems. I'd go as far to say it should be the default push --force behaviour. But it's still far from being an excuse to force a push. People who fetched before your rebase will still have lots of troubles, which could be easily avoided if you had reverted instead.

And since we're talking about git --push instances...

Why would anyone want to force push?

@linquize brought a good push force example on the comments: sensitive data. You've wrongly leaked data that shouldn't be pushed. If you're fast enough, you can "fix"* it by forcing a push on top.

* The data will still be on the remote unless you also do a garbage collect, or clean it somehow. There is also the obvious potential for it to be spread by others who'd fetched it already, but you get the idea.

This resolved the problem for me. For more details, you can follow the github issue here: https://github.com/angular/angular/issues/7144

Adding this into my styles.xml worked for me

Access-Engine does not support

SELECT count(DISTINCT....) FROM ...

You have to do it like this:

SELECT count(*) 
FROM
(SELECT DISTINCT Name FROM table1)

Its a little workaround... you're counting a DISTINCT selection.

Declare Array: int[] arr;

Initialize Array: int[] arr = new int[10]; 10 represents the number of elements allowed in the array

Declare Multidimensional Array: int[][] arr;

Initialize Multidimensional Array: int[][] arr = new int[10][17]; 10 rows and 17 columns and 170 elements because 10 times 17 is 170.

Initializing an array means specifying the size of it.

--create the user for the web server to connect as:

create role webgui noinherit login password 's3cr3t';

--let webgui set role to neil:

grant neil to webgui; --this looks backwards but is correct.

webgui is now in the neil group, so webgui can call set role neil . However, webgui did not inherit neil's permissions.

Later, login as webgui:

psql -d some_database -U webgui
(enter s3cr3t as password)

set role neil;

webgui does not need superuser permission for this.

You want to set role at the beginning of a database session and reset it at the end of the session. In a web app, this corresponds to getting a connection from your database connection pool and releasing it, respectively. Here's an example using Tomcat's connection pool and Spring Security:

public class SetRoleJdbcInterceptor extends JdbcInterceptor {

    @Override
    public void reset(ConnectionPool connectionPool, PooledConnection pooledConnection) {

        Authentication authentication = SecurityContextHolder.getContext().getAuthentication();

        if(authentication != null) {
            try {

                /* 
                  use OWASP's ESAPI to encode the username to avoid SQL Injection. Can't use parameters with SET ROLE. Need to write PG codec.

                  Or use a whitelist-map approach
                */
                String username = ESAPI.encoder().encodeForSQL(MY_CODEC, authentication.getName());

                Statement statement = pooledConnection.getConnection().createStatement();
                statement.execute("set role \"" + username + "\"");
                statement.close();
            } catch(SQLException exp){
                throw new RuntimeException(exp);
            }
        }
    }

    @Override
    public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {

        if("close".equals(method.getName())){
            Statement statement = ((Connection)proxy).createStatement();
            statement.execute("reset role");
            statement.close();
        }

        return super.invoke(proxy, method, args);
    }
}

It's possible that you already have the Lombok plugin, and still the generated methods are not recognised by Android Studio. In such case the plugin might be out of date, so the solution is to simply update it.

Preferences -> Plugins -> Lombok Plugin -> Update Plugin

Use

$(document).on("click", "#btn_a", function(){
  alert ('button clicked');
});

to add the listener for the dynamically created button.

alert($("#btn_a").val());

will give you the value of the button

I just wanted to add, that you can also use de-structuring to refactor the code and make it look neater.

inputChangeHandler: function ({ target: { id, value }) {
    this.setState({ [id]: value });
},

If you're using bash you can just say

if grep -q "$SOURCE" <<< "$LIST" ; then
    ...
fi

Great answer, adeneo.

It took me a little while to figure out how to make your answer more generic (so that I could load an array of code-defined scripts). Callback gets called when all scripts have loaded and executed. Here is my solution:

    function loadMultipleScripts(scripts, callback){
        var array = [];

        scripts.forEach(function(script){
            array.push($.getScript( script ))
        });

        array.push($.Deferred(function( deferred ){
                    $( deferred.resolve );
                }));

        $.when.apply($, array).done(function(){
                if (callback){
                    callback();
                }
            });
    }

You must declare the reportfile as variable for console.

Problem is all the Dokumentations you can find are not running so .. I was give 1 day of my live to find the right way ....

Example: for batch/console

cmd.exe /K set FFREPORT=file='C:\ffmpeg\proto\test.log':level=32 && C:\ffmpeg\bin\ffmpeg.exe -loglevel warning -report -i inputfile f outputfile

Exemple Javascript:

var reortlogfile = "cmd.exe /K set FFREPORT=file='C:\ffmpeg\proto\" + filename + ".log':level=32 && C:\ffmpeg\bin\ffmpeg.exe" .......;

You can change the dir and filename how ever you want.

MongoDB 2.2's new $elemMatch projection operator provides another way to alter the returned document to contain only the first matched shapes element:

db.test.find(
    {"shapes.color": "red"}, 
    {_id: 0, shapes: {$elemMatch: {color: "red"}}});

Returns:

{"shapes" : [{"shape": "circle", "color": "red"}]}

In 2.2 you can also do this using the $ projection operator, where the $ in a projection object field name represents the index of the field's first matching array element from the query. The following returns the same results as above:

db.test.find({"shapes.color": "red"}, {_id: 0, 'shapes.$': 1});

MongoDB 3.2 Update

Starting with the 3.2 release, you can use the new $filter aggregation operator to filter an array during projection, which has the benefit of including all matches, instead of just the first one.

db.test.aggregate([
    // Get just the docs that contain a shapes element where color is 'red'
    {$match: {'shapes.color': 'red'}},
    {$project: {
        shapes: {$filter: {
            input: '$shapes',
            as: 'shape',
            cond: {$eq: ['$$shape.color', 'red']}
        }},
        _id: 0
    }}
])

Results:

[ 
    {
        "shapes" : [ 
            {
                "shape" : "circle",
                "color" : "red"
            }
        ]
    }
]

Here are 4 ways to insert data into a table.

1. Simple insertion when the table column sequence is known.

   INSERT INTO Table1 VALUES (1,2,...)

2. Simple insertion into specified columns of the table.

   INSERT INTO Table1(col2,col4) VALUES (1,2)

3. Bulk insertion when...

   1. You wish to insert every column of Table2 into Table1
   2. You know the column sequence of Table2
   3. You are certain that the column sequence of Table2 won't change while this statement is being used (perhaps you the statement will only be used once).

   INSERT INTO Table1 {Column sequence} SELECT * FROM Table2

4. Bulk insertion of selected data into specified columns of Table2.

.

INSERT INTO Table1 (Column1,Column2 ....)
    SELECT Column1,Column2...
       FROM Table2

You might be after something that the scrollTo plugin from Ariel Flesler does really well.

http://demos.flesler.com/jquery/scrollTo/

If none of these work, try getBaseContext(), instead of context or this.

Interfaces can not contain any implementation (including default values). You need to switch to abstract class.

It is worth mentioning here Ray as well,
it's a distributed computation framework, that has it's own implementation for pandas in a distributed way.

Just replace the pandas import, and the code should work as is:

# import pandas as pd
import ray.dataframe as pd

#use pd as usual

can read more details here:

https://rise.cs.berkeley.edu/blog/pandas-on-ray/

One idea:

try {
    int i = Integer.parseInt(myString);
    if (i < 0) {
        // Error, negative input
    }
} catch (NumberFormatException e) {
    // Error, not a number.
}

There is also, in commons-lang library the CharUtils class that provides the methods isAsciiNumeric() to check that a character is a number, and isAsciiAlpha() to check that the character is a letter...

If you're on a mac, by far the simplest way to install is to use easy_install

sudo easy_install boto3

Taking this one step further, to save a file to a relative directory, you can use the replace function. Say you have your workbook saved in: c:\property\california\sacramento\workbook.xlsx, use this to move the property to berkley:

workBookPath = Replace(ActiveWorkBook.path, "sacramento", "berkley")
myWorkbook.SaveAs(workBookPath & "\" & "newFileName.xlsx"

Only works if your file structure contains one instance of the text used to replace. YMMV.

Use Datatable.Default.Sort property and then bind it to the datagridview.

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

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

Others have already addressed the other issues, so I'll just look at one point: do you ever want to manually delete an object.

The answer is yes. @DavidSchwartz gave one example, but it's a fairly unusual one. I'll give an example that's under the hood of what a lot of C++ programmers use all the time: std::vector (and std::deque, though it's not used quite as much).

As most people know, std::vector will allocate a larger block of memory when/if you add more items than its current allocation can hold. When it does this, however, it has a block of memory that's capable of holding more objects than are currently in the vector.

To manage that, what vector does under the covers is allocate raw memory via the Allocator object (which, unless you specify otherwise, means it uses ::operator new). Then, when you use (for example) push_back to add an item to the vector, internally the vector uses a placement new to create an item in the (previously) unused part of its memory space.

Now, what happens when/if you erase an item from the vector? It can't just use delete -- that would release its entire block of memory; it needs to destroy one object in that memory without destroying any others, or releasing any of the block of memory it controls (for example, if you erase 5 items from a vector, then immediately push_back 5 more items, it's guaranteed that the vector will not reallocate memory when you do so.

To do that, the vector directly destroys the objects in the memory by explicitly calling the destructor, not by using delete.

If, perchance, somebody else were to write a container using contiguous storage roughly like a vector does (or some variant of that, like std::deque really does), you'd almost certainly want to use the same technique.

Just for example, let's consider how you might write code for a circular ring-buffer.

#ifndef CBUFFER_H_INC
#define CBUFFER_H_INC

template <class T>
class circular_buffer {
    T *data;
    unsigned read_pos;
    unsigned write_pos;
    unsigned in_use;
    const unsigned capacity;
public:
    circular_buffer(unsigned size) :
        data((T *)operator new(size * sizeof(T))),
        read_pos(0),
        write_pos(0),
        in_use(0),
        capacity(size)
    {}

    void push(T const &t) {
        // ensure there's room in buffer:
        if (in_use == capacity) 
            pop();

        // construct copy of object in-place into buffer
        new(&data[write_pos++]) T(t);
        // keep pointer in bounds.
        write_pos %= capacity;
        ++in_use;
    }

    // return oldest object in queue:
    T front() {
        return data[read_pos];
    }

    // remove oldest object from queue:
    void pop() { 
        // destroy the object:
        data[read_pos++].~T();

        // keep pointer in bounds.
        read_pos %= capacity;
        --in_use;
    }
  
~circular_buffer() {
    // first destroy any content
    while (in_use != 0)
        pop();

    // then release the buffer.
    operator delete(data); 
}

};

#endif

Unlike the standard containers, this uses operator new and operator delete directly. For real use, you probably do want to use an allocator class, but for the moment it would do more to distract than contribute (IMO, anyway).

You need to add two jars into the WEB-INF/lib directory or your webapp (or lib directory of the server):

• mail.jar - contains the actual smtp implmentation
• activation.jar - needed by mail.jar

There should be no semicolon here:

class WordGame;

...but there should be one at the end of your class definition:

...
private:
    string theWord;
}; // <-- Semicolon should be at the end of your class definition

I was following along the Vue documentation at https://vuejs.org/v2/guide/index.html when I ran into this issue.

Later they clarify the syntax:

So far, we’ve only registered components globally, using Vue.component:

   Vue.component('my-component-name', {
       // ... options ...
   })

Globally registered components can be used in the template of any root Vue instance (new Vue) created afterwards – and even inside all >subcomponents of that Vue instance’s component tree.

(https://vuejs.org/v2/guide/components.html#Organizing-Components)

So as Umesh Kadam says above, just make sure the global component definition comes before the var app = new Vue({}) instantiation.

This can be solved with an assignment tag:

from django import template

register = template.Library()

@register.assignment_tag
def query(qs, **kwargs):
    """ template tag which allows queryset filtering. Usage:
          {% query books author=author as mybooks %}
          {% for book in mybooks %}
            ...
          {% endfor %}
    """
    return qs.filter(**kwargs)

There's no need to set a fact.

    - shell: cat "hello"
      register: cat_contents

    - shell: echo "I cat hello"
      when: cat_contents.stdout == "hello"

The question relates to serving via artisan and so Jrop's answer is ideal in that case. I.e, error_log logging to the apache log.

However, if your serving via a standard web server then simply use the Laravel specific logging functions:

\Log::info('This is some useful information.');

\Log::warning('Something could be going wrong.');

\Log::error('Something is really going wrong.');

With current versions of laravel like this for info:

info('This is some useful information.');

This logs to Laravel's log file located at /laravel/storage/logs/laravel-<date>.log (laravel 5.0). Monitor the log - linux/osx: tail -f /laravel/storage/logs/laravel-<date>.log

• Laravel 5.0 http://laravel.com/docs/5.0/errors
• Laravel 4.2: http://laravel.com/docs/4.2/errors

It's the ternary form of the if-else operator. The above statement basically reads like this:

if ($add_review) then {
    return FALSE; //$add_review evaluated as True
} else {
    return $arg //$add_review evaluated as False
}

See here for more details on ternary op in PHP: http://www.addedbytes.com/php/ternary-conditionals/

Cleaning up...

In a nutshell :

List/Array Sort() :

• Unstable sort.
• Done in-place.
• Use Introsort/Quicksort.
• Custom comparison is done by providing a comparer. If comparison is expensive, it might be slower than OrderBy() (which allow to use keys, see below).

OrderBy/ThenBy() :

• Stable sort.
• Not in-place.
• Use Quicksort. Quicksort is not a stable sort. Here is the trick : when sorting, if two elements have equal key, it compares their initial order (which has been stored before sorting).
• Allows to use keys (using lambdas) to sort elements on their values (eg : x => x.Id). All keys are extracted first before sorting. This might result in better performance than using Sort() and a custom comparer.

Sources: MDSN, reference source and dotnet/coreclr repository (GitHub).

Some of the statements listed above are based on current .NET framework implementation (4.7.2). It might change in the future.

private static byte[] charArrayToByteArray(char[] c_array) {
        byte[] b_array = new byte[c_array.length];
        for(int i= 0; i < c_array.length; i++) {
            b_array[i] = (byte)(0xFF & (int)c_array[i]);
        }
        return b_array;
}

If array item and list item are same

List<object> list=myArray.ToList();

More simple,

echo $line | sed 's/\s/\n/g'

\s --> whitespace character (space, tab, NL, FF, VT, CR). In many systems also valid [:space:]

\n --> new line

Not really. This is normally done using javascript.

there is a good discussion of ways of doing this here...

You can use a JavaScript library such as JXtension which gives the user the ability to make a color lighter or darker. If you would like to find documentation for this brand new library, click here. You can also use JXtension to combine one color with another.

You should had in mind that...

contructor()

constructor(a:any, b:any, c:any)

It's the same as new() or new("a","b","c")

Thus

constructor(a?:any, b?:any, c?:any)

is the same above and is more flexible...

new() or new("a") or new("a","b") or new("a","b","c")

There's no concept of "project" in svn. So, feel free to delete whatever you think belongs to the project.

Depends on the RDBMS or even the JDBC driver.

Most of the times you can use java.sql.Timestamp most of the times along with a prepared statement:

pstmt.setTimestamp( index, new Timestamp( yourJavaUtilDateInstance.getTime() );

=$W$4<=TODAY()

Returns true for dates up to and including today, false otherwise.

Use android vollley, it is very fast and you can betterm manipulate requests. Send post request using Volley and receive in PHP

Basically, you will create a map with key-value params for the php request(POST/GET), the php will do the desired processing and you will return the data as JSON(json_encode()). Then you can either parse the JSON as needed or use GSON from Google to let it do the parsing.

to complete of Pit answer and for better perfromance : get all in one query and use NextResult method.

using (var sqlCon = new SqlConnection("Server=127.0.0.1;Database=MyDb;User Id=Me;Password=glop;"))

    com.CommandText = "select * from BigTable;select @@ROWCOUNT;";
    using (var reader = com.ExecuteReader())
    {
        while(reader.read()){
            //iterate code
        }
        int totalRow = 0 ;
        reader.NextResult(); // 
        if(reader.read()){
            totalRow = (int)reader[0];

    sqlCon.Close();
}

php-execute-a-background-process has some good suggestions. I think mine is pretty good, but I'm biased :)

I had an issue with my Apache configuration after installing a GoDaddy certificate on a subdomain. I originally thought it might be an issue with Node not sending a Server Name Indicator (SNI), but that wasn't the case. Analyzing the subdomain's SSL certificate with https://www.ssllabs.com/ssltest/ returned the error Chain issues: Incomplete.

After adding the GoDaddy provided gd_bundle-g2-g1.crt file via the SSLCertificateChainFile Apache directive, Node was able to connect over HTTPS and the error went away.

I have faced this issue multiple times and decided to write a function that is as generic as possible. Have a look and feel free to modify anything

function typeOf(obj) {
    if ( typeof(obj) == 'object' ) {
        if (obj.length)
            return 'array';
        else
            return 'object';
    } else
    return typeof(obj);
}

function objToArray(obj, ignoreKeys) {
    var arr = [];
    if (typeOf(obj) == 'object') {
        for (var key in obj) {
            if (typeOf(obj[key]) == 'object') {
                if (ignoreKeys)
                    arr.push(objToArray(obj[key],ignoreKeys));
                else
                    arr.push([key,objToArray(obj[key])]);
            }
            else
                arr.push(obj[key]);
        }
    }else if (typeOf(obj) == 'array') {
        for (var key=0;key<obj.length;key++) {
            if (typeOf(obj[key]) == 'object')
                arr.push(objToArray(obj[key]));
            else
                arr.push(obj[key]);
        }
    }
    return arr;
}

mail [-s subject] [-c ccaddress] [-b bccaddress] toaddress

-c and -b are optional.

-s : Specify subject;if subject contains spaces, use quotes.

-c : Send carbon copies to list of users seperated by comma.

-b : Send blind carbon copies to list of users seperated by comma.

Hope my answer clarifies your doubt.

A late answer I know, but it still a common question, I would like to add another answer that It worked for me, with only using a single line insert into statement, and I think it is straightforward, without creating any new table (since it could be an issue with CREATE TEMPORARY TABLE permissions):

INSERT INTO invoices (col_1, col_2, col_3, ... etc)
  SELECT
    t.col_1,
    t.col_2,
    t.col_3,
    ...
    t.updated_date,
  FROM invoices t;

The solution is working for AUTO_INCREMENT id column, otherwise, you can add ID column as well to statement:

INSERT INTO invoices (ID, col_1, col_2, col_3, ... etc)
  SELECT
    MAX(ID)+1,
    t.col_1,
    t.col_2,
    t.col_3,
    ... etc ,
  FROM invoices t;

It is really easy and straightforward, you can update anything else in a single line without any second update statement for later, (ex: update a title column with extra text or replacing a string with another), also you can be specific with what exactly you want to duplicate, if all then it is, if some, you can do so.

As the accepted solution of @Shane is not supported in RStudio (see here) as of now (Sep 2015), I would like to add an advice to @James Thompson answer regarding workflow:

If you use SumatraPDF as viewer you do not need to close the PDF file before making changes to it. Sumatra does not put a opened file in read-only and thus does not prevent it from being overwritten. Therefore, once you opened your PDF file with Sumatra, changes out of RStudio (or any other R IDE) are immediately displayed in Sumatra.

An assertion Error is thrown when say "You have written a code that should not execute at all costs because according to you logic it should not happen. BUT if it happens then throw AssertionError. And you don't catch it." In such a case you throw an Assertion error.

Note: Assertion Error comes under java.lang.Error And Errors not meant to be caught.

Here's a couple ways to do this using the Joda-Time 2.3 library.

One way is to use the simple isBefore and isAfter methods on DateTime instances. By the way, DateTime in Joda-Time is similar in concept to a java.util.Date (a moment in time on the timeline of the Universe) but includes a time zone.

Another way is to build an Interval in Joda-Time. The contains method tests if a given DateTime occurs within the span of time covered by the Interval. The beginning of the Interval is inclusive, but the endpoint is exclusive. This approach is known as "Half-Open", symbolically [).

See both ways in the following code example.

Convert the java.util.Date instances to Joda-Time DateTime instances. Simply pass the Date instance to constructor of DateTime. In practice you should also pass a specific DateTimeZone object rather than rely on JVM’s default time zone.

DateTime dateTime1 = new DateTime( new java.util.Date() ).minusWeeks( 1 );
DateTime dateTime2 = new DateTime( new java.util.Date() );
DateTime dateTime3 = new DateTime( new java.util.Date() ).plusWeeks( 1 );

Compare by testing for before/after…

boolean is1After2 = dateTime1.isAfter( dateTime2 );
boolean is2Before3 = dateTime2.isBefore( dateTime3 );

boolean is2Between1And3 = ( ( dateTime2.isAfter( dateTime1 ) ) && ( dateTime2.isBefore( dateTime3 ) ) );

Using the Interval approach instead of isAfter/isBefore…

Interval interval = new Interval( dateTime1, dateTime3 );
boolean intervalContainsDateTime2 = interval.contains( dateTime2 );

Dump to console…

System.out.println( "DateTimes: " + dateTime1 + " " + dateTime1 + " " + dateTime1 );

Your JSON string is malformed: the type of center is an array of invalid objects. Replace [ and ] with { and } in the JSON string around longitude and latitude so they will be objects:

[
    {
        "name" : "New York",
        "number" : "732921",
        "center" : {
                "latitude" : 38.895111, 
                "longitude" : -77.036667
            }
    },
    {
        "name" : "San Francisco",
        "number" : "298732",
        "center" : {
                "latitude" : 37.783333, 
                "longitude" : -122.416667
            }
    }
]

In Python 3, / is float division

In Python 2, / is integer division (assuming int inputs)

In both 2 and 3, // is integer division

(To get float division in Python 2 requires either of the operands be a float, either as 20. or float(20))

at first : CREATE connection

$conn =  new mysqli('localhost', 'User DB', 'Pass DB', 'Table name');

and then get the record target :

$query = "SELECT id FROM games LIMIT 1"; // for example query
$result = $conn->query($query); // run query
if($result->num_rows){ //if exist something
    $ret = $result->fetch_array(MYSQLI_ASSOC); //fetch data
}else{
    $ret = false;
}
var_dump($ret);

Kotlin: (If anyone needs)

var mText = text.substring(0, text.length.coerceAtMost(20))

I suppose that calling Array.prototype functions on instances of HTMLCollection is a much better option than converting collections to arrays (e.g.,[...collection] or Array.from(collection)), because in the latter case a collection is unnecessarily implicitly iterated and a new array object is created, and this eats up additional resources. Array.prototype iterating functions can be safely called upon objects with consecutive numeric keys starting from [0] and a length property with a valid number value of such keys' quantity (including, e.g., instances of HTMLCollection and FileList), so it's a reliable way. Also, if there is a frequent need in such operations, an empty array [] can be used for quick access to Array.prototype functions; or a shortcut for Array.prototype can be created instead. A runnable example:

const _ = Array.prototype;
const collection = document.getElementById('ol').children;
alert(_.reduce.call(collection, (acc, { textContent }, i) => {
  return acc += `${i+1}) ${textContent}` + '\n';
}, ''));

<ol id="ol">
    <li>foo</li>
    <li>bar</li>
    <li>bat</li>
    <li>baz</li>
</ol>

Like this:

import java.util.*;
Set<Integer> a = new HashSet<Integer>();
a.add( 1);
a.add( 2);
a.add( 3);

Or adding from an Array/ or multiple literals; wrap to a list, first.

Integer[] array = new Integer[]{ 1, 4, 5};
Set<Integer> b = new HashSet<Integer>();
b.addAll( Arrays.asList( b));         // from an array variable
b.addAll( Arrays.asList( 8, 9, 10));  // from literals

To get the intersection:

// copies all from A;  then removes those not in B.
Set<Integer> r = new HashSet( a);
r.retainAll( b);
// and print;   r.toString() implied.
System.out.println("A intersect B="+r);

1. Click on Packages --> Commmand Palette --> Select Toggle.
2. Type Install Packages and Themes.
3. Search for Script and then install it.
4. Press Command + I to run the code (on Mac)

A possible solution:

    /#include/!{p;d;}
    i\
    #include "newfile.h"
    :a
    n
    ba

Explanation:

• read lines until we find the #include, print these lines then start new cycle
• insert the new include line
• enter a loop that just reads lines (by default sed will also print these lines), we won't get back to the first part of the script from here

With Spring Boot 1.4+ new cool classes for easier exception handling were added that helps in removing the boilerplate code.

A new @RestControllerAdvice is provided for exception handling, it is combination of @ControllerAdvice and @ResponseBody. You can remove the @ResponseBody on the @ExceptionHandler method when use this new annotation.

i.e.

@RestControllerAdvice
public class GlobalControllerExceptionHandler {

    @ExceptionHandler(value = { Exception.class })
    @ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
    public ApiErrorResponse unknownException(Exception ex, WebRequest req) {
        return new ApiErrorResponse(...);
    }
}

For handling 404 errors adding @EnableWebMvc annotation and the following to application.properties was enough:
spring.mvc.throw-exception-if-no-handler-found=true

You can find and play with the sources here:

[f,x]=hist(data)

The area for each individual bar is height*width. Since MATLAB will choose equidistant points for the bars, so the width is:

delta_x = x(2) - x(1)

Now if we sum up all the individual bars the total area will come out as

A=sum(f)*delta_x

So the correctly scaled plot is obtained by

bar(x, f/sum(f)/(x(2)-x(1)))
