I agree with Ed. C# does not make this easy the way VB does with ReDim Preserve. Without a collection, you'll have to copy the array into a larger one.

Class.forName()-->forName() is the static method of Class class it returns Class class object used for reflection not user class object so you can only call Class class methods on it like getMethods(), getConstructors() etc.

If you care about only running static block of your(Runtime given) class and only getting information of methods,constructors,Modifier etc of your class you can do with this object which you get using Class.forName()

But if you want to access or call your class method (class which you have given at runtime) then you need to have its object so newInstance method of Class class do it for you.It create new instance of the class and return it to you .You just need to type-cast it to your class.

ex-: suppose Employee is your class then

Class a=Class.forName(args[0]); 

//args[0]=cmd line argument to give class at  runtime. 

Employee ob1=a.newInstance();

a.newInstance() is similar to creating object using new Employee().

now you can access all your class visible fields and methods.

git branch -D <branch-name>
git fetch <remote> <branch-name>
git checkout -b <branch-name> --track <remote>/<branch-name>

I found you can do this easily via the Cloud Flare service.

Set up a bucket, enable webhosting on the bucket and point the desired CNAME to that endpoint via Cloudflare... and pay for the service of course... but $5-$20 VS $600 is much easier to stomach.

You are using aggregate function which not getting the items to perform action , you must verify linq query is giving some result as below:

var maxOrderLevel =sdv.Any()? sdv.Max(s => s.nOrderLevel):0

There are several ways to parse cmdline args (e.g. GNU getopt (not portable) vs BSD (MacOS) getopt vs getopts) - all problematic. This solution

• is portable!
• has zero dependencies, only relies on bash built-ins
• allows for both short and long options
• handles whitespace or simultaneously the use of = separator between option and argument
• supports concatenated short option style -vxf
• handles option with optional arguments (E.g. --color vs --color=always),
• correctly detects and reports unknown options
• supports -- to signal end of options, and
• doesn't require code bloat compared with alternatives for the same feature set. I.e. succinct, and therefore easier to maintain

Examples: Any of

# flag
-f
--foo

# option with required argument
-b"Hello World"
-b "Hello World"
--bar "Hello World"
--bar="Hello World"

# option with optional argument
--baz
--baz="Optional Hello"

Michael Krelin's answer is close is not entirely safe, since it can be wrong in rare situations. The problem is that intervals in PostgreSQL do not have context with regards to things like daylight savings. Intervals store things internally as months, days, and seconds. Months aren't an issue in this case since subtracting two timestamps just use days and seconds but 'days' can be a problem.

If your subtraction involves daylight savings change-overs, a particular day might be considered 23 or 25 hours respectively. The interval will take that into account, which is useful for knowing the amount of days that passed in the symbolic sense but it would give an incorrect number of the actual hours that passed. Epoch on the interval will just multiply all days by 24 hours.

For example, if a full 'short' day passes and an additional hour of the next day, the interval will be recorded as one day and one hour. Which converted to epoch/3600 is 25 hours. But in reality 23 hours + 1 hour should be a total of 24 hours.

So the safer method is:

(EXTRACT(EPOCH FROM current_timestamp) - EXTRACT(EPOCH FROM somedate))/3600

As Michael mentioned in his follow-up comment, you'll also probably want to use floor() or round() to get the result as an integer value.

Ask how accidental closures might cause memory leaks in IE.

i got the same error, but with no relation to Hibernate. I got scared here from all frightening suggestions, which i guess relevant in case of Hibernate and lazy loading... However, in my case i got the error since in an inner class i had no getters/setters, so the BeanSerializer could not serialize the data...

Adding getters & setters resolved the problem.

For non-object return types, you have to assign the value to the name of your function, like this:

Public Function test() As Integer
    test = 1
End Function

Example usage:

Dim i As Integer
i = test()

If the function returns an Object type, then you must use the Set keyword like this:

Public Function testRange() As Range
    Set testRange = Range("A1")
End Function

Example usage:

Dim r As Range
Set r = testRange()

Note that assigning a return value to the function name does not terminate the execution of your function. If you want to exit the function, then you need to explicitly say Exit Function. For example:

Function test(ByVal justReturnOne As Boolean) As Integer
    If justReturnOne Then
        test = 1
        Exit Function
    End If
    'more code...
    test = 2
End Function

When some elements lack ID, I use jQuery like this:

$(document).ready(function()
{
    $('.myclass').attr('id', 'myid');
});

This might be a strange solution, but maybe someone find it useful.

Another option is to use the Aggregate extension rather than Join:

String s = myDict.Select(x => x.Key + "=" + x.Value).Aggregate((s1, s2) => s1 + ";" + s2);

Please try below code :

public T? GetParsedOrDefaultValue<T>(string valueToParse) where T : struct, IComparable
{
 if(string.EmptyOrNull(valueToParse))return null;
  try
  {
     // return parsed value
     return (T) Convert.ChangeType(valueToParse, typeof(T));
  }
  catch(Exception)
  {
   //default as null value
   return null;
  }
 return null;
}

Actually using 100% will not make the image bigger if the image is smaller than the div size you specified. You need to set one of the dimensions, height or width in order to have all images fill the space. In my experience it's better to have the height set so each row is the same size, then all items wrap to next line properly. This will produce an output similar to fotolia.com (stock image website)

with css:

parent {
   width: 42px; /* I took the width from your post and placed it in css */
   height: 42px;
}

/* This will style any <img> element in .parent div */
.parent img {
   height: 42px;
}

without:

<div style="height:42px;width:42px">
    <img style="height:42px" src="http://someimage.jpg">
</div>

In python a list knows its length, so you can just do len(sys.argv) to get the number of elements in argv.

I find it easiest to understand move semantics with example code. Let's start with a very simple string class which only holds a pointer to a heap-allocated block of memory:

#include <cstring>
#include <algorithm>

class string
{
    char* data;

public:

    string(const char* p)
    {
        size_t size = std::strlen(p) + 1;
        data = new char[size];
        std::memcpy(data, p, size);
    }

Since we chose to manage the memory ourselves, we need to follow the rule of three. I am going to defer writing the assignment operator and only implement the destructor and the copy constructor for now:

    ~string()
    {
        delete[] data;
    }

    string(const string& that)
    {
        size_t size = std::strlen(that.data) + 1;
        data = new char[size];
        std::memcpy(data, that.data, size);
    }

The copy constructor defines what it means to copy string objects. The parameter const string& that binds to all expressions of type string which allows you to make copies in the following examples:

string a(x);                                    // Line 1
string b(x + y);                                // Line 2
string c(some_function_returning_a_string());   // Line 3

Now comes the key insight into move semantics. Note that only in the first line where we copy x is this deep copy really necessary, because we might want to inspect x later and would be very surprised if x had changed somehow. Did you notice how I just said x three times (four times if you include this sentence) and meant the exact same object every time? We call expressions such as x "lvalues".

The arguments in lines 2 and 3 are not lvalues, but rvalues, because the underlying string objects have no names, so the client has no way to inspect them again at a later point in time. rvalues denote temporary objects which are destroyed at the next semicolon (to be more precise: at the end of the full-expression that lexically contains the rvalue). This is important because during the initialization of b and c, we could do whatever we wanted with the source string, and the client couldn't tell a difference!

C++0x introduces a new mechanism called "rvalue reference" which, among other things, allows us to detect rvalue arguments via function overloading. All we have to do is write a constructor with an rvalue reference parameter. Inside that constructor we can do anything we want with the source, as long as we leave it in some valid state:

    string(string&& that)   // string&& is an rvalue reference to a string
    {
        data = that.data;
        that.data = nullptr;
    }

What have we done here? Instead of deeply copying the heap data, we have just copied the pointer and then set the original pointer to null (to prevent 'delete[]' from source object's destructor from releasing our 'just stolen data'). In effect, we have "stolen" the data that originally belonged to the source string. Again, the key insight is that under no circumstance could the client detect that the source had been modified. Since we don't really do a copy here, we call this constructor a "move constructor". Its job is to move resources from one object to another instead of copying them.

Congratulations, you now understand the basics of move semantics! Let's continue by implementing the assignment operator. If you're unfamiliar with the copy and swap idiom, learn it and come back, because it's an awesome C++ idiom related to exception safety.

    string& operator=(string that)
    {
        std::swap(data, that.data);
        return *this;
    }
};

Huh, that's it? "Where's the rvalue reference?" you might ask. "We don't need it here!" is my answer :)

Note that we pass the parameter that by value, so that has to be initialized just like any other string object. Exactly how is that going to be initialized? In the olden days of C++98, the answer would have been "by the copy constructor". In C++0x, the compiler chooses between the copy constructor and the move constructor based on whether the argument to the assignment operator is an lvalue or an rvalue.

So if you say a = b, the copy constructor will initialize that (because the expression b is an lvalue), and the assignment operator swaps the contents with a freshly created, deep copy. That is the very definition of the copy and swap idiom -- make a copy, swap the contents with the copy, and then get rid of the copy by leaving the scope. Nothing new here.

But if you say a = x + y, the move constructor will initialize that (because the expression x + y is an rvalue), so there is no deep copy involved, only an efficient move. that is still an independent object from the argument, but its construction was trivial, since the heap data didn't have to be copied, just moved. It wasn't necessary to copy it because x + y is an rvalue, and again, it is okay to move from string objects denoted by rvalues.

To summarize, the copy constructor makes a deep copy, because the source must remain untouched. The move constructor, on the other hand, can just copy the pointer and then set the pointer in the source to null. It is okay to "nullify" the source object in this manner, because the client has no way of inspecting the object again.

I hope this example got the main point across. There is a lot more to rvalue references and move semantics which I intentionally left out to keep it simple. If you want more details please see my supplementary answer.

Interestingly, if the break tag is written in full-form as follows:

then the CSS line-height:145% works. If the break tag is written as:

then it doesn't work, at least in Chrome, IE and firefox. Weird!

Everythings works well. You can't use divtag.onclick, becease "onclick" attribute doesn't exist. You need first create this attribute by using .setAttribute(). Look on this http://reference.sitepoint.com/javascript/Element/setAttribute . You should read documentations first before you start giving "-".

The reason the compiler is generating an error is that only a limited amount of characters may follow a backslash. % is not a valid character.

If you are using qmake, the standard Qt build system, just add a line to the .pro file as documented in the qmake Variable Reference:

INCLUDEPATH += <your path>

If you are using your own build system, you create a project by selecting "Import of Makefile-based project". This will create some files in your project directory including a file named <your project name>.includes. In that file, simply list the paths you want to include, one per line. Really all this does is tell Qt Creator where to look for files to index for auto completion. Your own build system will have to handle the include paths in its own way.

As explained in the Qt Creator Manual, <your path> must be an absolute path, but you can avoid OS-, host- or user-specific entries in your .pro file by using $$PWD which refers to the folder that contains your .pro file, e.g.

INCLUDEPATH += $$PWD/code/include

Not the best way to error log, but you can always set everything to an array for the promiseAll, and store the resulting results into new variables.

If you use graphQL you need to postprocess the response regardless and if it doesn't find the correct reference it'll crash the app, narrowing down where the problem is at

const results = await Promise.all([
  this.props.client.query({
    query: GET_SPECIAL_DATES,
  }),
  this.props.client.query({
    query: GET_SPECIAL_DATE_TYPES,
  }),
  this.props.client.query({
    query: GET_ORDER_DATES,
  }),
]).catch(e=>console.log(e,"error"));
const specialDates = results[0].data.specialDates;
const specialDateTypes = results[1].data.specialDateTypes;
const orderDates = results[2].data.orders;

if you install git with git bash, you get SCP available on windows.

The whole git resetting business looked far to complicating for me.

So I did something along the lines to get my src folder in the state i had a few commits ago

# reset the local state
git reset <somecommit> --hard 
# copy the relevant part e.g. src (exclude is only needed if you specify .)
tar cvfz /tmp/current.tgz --exclude .git  src
# get the current state of git
git pull
# remove what you don't like anymore
rm -rf src
# restore from the tar file
tar xvfz /tmp/current.tgz
# commit everything back to git
git commit -a
# now you can properly push
git push

This way the state of affairs in the src is kept in a tar file and git is forced to accept this state without too much fiddling basically the src directory is replaced with the state it had several commits ago.

No, you can specify the list as a keyword argument to your function.

alist = []
def fn(alist=alist):
    alist.append(1)
fn()
print alist    # [1]

I'd say it's bad practice though. Kind of too hackish. If you really need to use a globally available singleton-like data structure, I'd use the module level variable approach, i.e. put 'alist' in a module and then in your other modules import that variable:

In file foomodule.py:

alist = []

In file barmodule.py:

import foomodule
def fn():
    foomodule.alist.append(1)
print foomodule.alist    # [1]

Both pandas and matplotlib.dates use matplotlib.units for locating the ticks.

But while matplotlib.dates has convenient ways to set the ticks manually, pandas seems to have the focus on auto formatting so far (you can have a look at the code for date conversion and formatting in pandas).

So for the moment it seems more reasonable to use matplotlib.dates (as mentioned by @BrenBarn in his comment).

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt 
import matplotlib.dates as dates

idx = pd.date_range('2011-05-01', '2011-07-01')
s = pd.Series(np.random.randn(len(idx)), index=idx)

fig, ax = plt.subplots()
ax.plot_date(idx.to_pydatetime(), s, 'v-')
ax.xaxis.set_minor_locator(dates.WeekdayLocator(byweekday=(1),
                                                interval=1))
ax.xaxis.set_minor_formatter(dates.DateFormatter('%d\n%a'))
ax.xaxis.grid(True, which="minor")
ax.yaxis.grid()
ax.xaxis.set_major_locator(dates.MonthLocator())
ax.xaxis.set_major_formatter(dates.DateFormatter('\n\n\n%b\n%Y'))
plt.tight_layout()
plt.show()

This error is weird as many proposed answers and got mixed solutions. I tried them, add them. It was only when I added pip install --upgrade pip finally removed the error for me. But I have no time to isolate which is which,so this is just fyi.

Module in Ruby, to a degree, corresponds to Java abstract class -- has instance methods, classes can inherit from it (via include, Ruby guys call it a "mixin"), but has no instances. There are other minor differences, but this much information is enough to get you started.

In my experience, first name/last name fields should be at least 48 characters -- there are names from some countries such as Malaysia or India that are very long in their full form.

Phone numbers and postcodes you should always treat as text, not numbers. The normal reason given is that there are postcodes that begin with 0, and in some countries, phone numbers can also begin with 0. But the real reason is that they aren't numbers -- they're identifiers that happen to be made up of numerical digits (and that's ignoring countries like Canada that have letters in their postcodes). So store them in a text field.

In MySQL you can use VARCHAR fields for this type of information. Whilst it sounds lazy, it means you don't have to be too concerned about the right minimum size.

If the children have FKs linking them to the parent, then you can use DELETE CASCADE on the parent.

e.g.

CREATE TABLE supplier 
( supplier_id numeric(10) not null, 
 supplier_name varchar2(50) not null, 
 contact_name varchar2(50),  
 CONSTRAINT supplier_pk PRIMARY KEY (supplier_id) 
); 



CREATE TABLE products 
( product_id numeric(10) not null, 
 supplier_id numeric(10) not null, 
 CONSTRAINT fk_supplier 
   FOREIGN KEY (supplier_id) 
  REFERENCES supplier(supplier_id) 
  ON DELETE CASCADE 
); 

Delete the supplier, and it will delate all products for that supplier

Here is the small example

public class TryWithResource {

    public static void main(String[] args) {
        try (TestMe r = new TestMe()) {
            r.generalTest();
        } catch(Exception e) {
            System.out.println("From Exception Block");
        } finally {
            System.out.println("From Final Block");
        }
    }
}



public class TestMe implements AutoCloseable {

    @Override
    public void close() throws Exception {
        System.out.println(" From Close -  AutoCloseable  ");
    }

    public void generalTest() {
        System.out.println(" GeneralTest ");
    }
}

Here is the output:

GeneralTest 
From Close -  AutoCloseable  
From Final Block

Check this link

https://github.com/mayoff/uiimage-from-animated-gif/blob/master/uiimage-from-animated-gif/UIImage%2BanimatedGIF.h

and import these clases UIImage+animatedGIF.h,UIImage+animatedGIF.m

Use this code

 NSURL *urlZif = [[NSBundle mainBundle] URLForResource:@"dots64" withExtension:@"gif"];
 NSString *path=[[NSBundle mainBundle]pathForResource:@"bar180" ofType:@"gif"];
 NSURL *url=[[NSURL alloc] initFileURLWithPath:path];

Hope this is helpfull

You can also used below code

<html>
<head>
    <style>
        .labelClass{
            float: left;
            width: 113px;
        }
    </style>
</head>
<body>
  <form action="yourclassName.jsp">
    <span class="labelClass">First name: </span><input type="text" name="fname"><br>
    <span class="labelClass">Last name: </span><input type="text" name="lname"><br>
    <input type="submit" value="Submit">
  </form>
</body>
</html>

<div style="cursor: pointer;" onclick="theFunction()">

is the simplest thing that works.

Of course in the final solution you should separate the markup from styling (css) and behavior (javascript) - read on it on a list apart for good practices on not just solving this particular problem but in markup design in general.

In addition to setting the registry entry for AuthServerWhitelist you should also set AuthSchemes: "ntlm,negotiate" (or just "ntlm" as appropriate for your situation). Using the above templates the policy for that will be "Supported authentication schemes"

I think those can help for beginner: Naming convention of variables in c

1. You have to use Alphabetic Character (a-z, A-Z), Digit (0-9) and Under Score (_). It’s not allow to use any special Character like: %, $, #, @ etc. So, you can use user_name as variable but cannot use user&name.
2. Can not use white space between words. So, you can use user_name or username or username as variable but cannot use user name.
3. Can not start naming with digit. So, you can use user1 or user2 as variable but cannot use 1user.
4. It is case sensitive language. Uppercase and lowercase are significant. If you use a variable like username then you cannot use USERNAME or Username for father use.
5. You can not use any keyword (char, int, if, for, while etc) for variable declaration.
6. ANSI standard recognizes a length of 31 characters for a variable name

This is what I use:

public enum Quality {ENOUGH,BETTER,BEST;
                     private static final int amount = EnumSet.allOf(Quality.class).size();
                     private static Quality[] val = new Quality[amount];
                     static{ for(Quality q:EnumSet.allOf(Quality.class)){ val[q.ordinal()]=q; } }
                     public static Quality fromInt(int i) { return val[i]; }
                     public Quality next() { return fromInt((ordinal()+1)%amount); }
                    }

Seems like all these answers involve custom css on top of bootstrap. The answer I am providing utilizes only bootstrap so I hope it comes to use for those that want to limit customizations.

This was tested with Bootstrap V3.3.7

<footer class="navbar-default navbar-fixed-bottom">
    <div class="container-fluid">
        <div class="row">
            <div class="col-xs-offset-5 col-xs-2 text-center">
                <p>I am centered text<p>
            </div>
            <div class="col-xs-5"></div>
        </div>
    </div>
</footer>

IMO, implementation #1 is typical and being short and idiomatic for Perl trumps the others for that alone. A benchmark of the three choices might offer you insight into speed, at least.

Share application with title is you app_name, content is your application link

private static void shareApp(Context context) {
    final String appPackageName = BuildConfig.APPLICATION_ID;
    final String appName = context.getString(R.string.app_name);
    Intent shareIntent = new Intent(Intent.ACTION_SEND);
    shareIntent.setType("text/plain");
    String shareBodyText = "https://play.google.com/store/apps/details?id=" +
            appPackageName;
    shareIntent.putExtra(Intent.EXTRA_SUBJECT, appName);
    shareIntent.putExtra(Intent.EXTRA_TEXT, shareBodyText);
    context.startActivity(Intent.createChooser(shareIntent, context.getString(R.string
            .share_with)));
}

Open an elevated Command Prompt (run cmd as administrator). query your registry for available TT fonts to the console by:

    REG query "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Console\TrueTypeFont"

You'll see an output like :

    0    REG_SZ    Lucida Console
    00    REG_SZ    Consolas
    936    REG_SZ    *???
    932    REG_SZ    *MS ????

Now we need to add a TT font that supports the characters you need like Courier New, we do this by adding zeros to the string name, so in this case the next one would be "000" :

    REG ADD "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Console\TrueTypeFont" /v 000 /t REG_SZ /d "Courier New"

Now we implement UTF-8 support:

    REG ADD HKCU\Console /v CodePage /t REG_DWORD /d 65001 /f

Set default font to "Courier New":

    REG ADD HKCU\Console /v FaceName /t REG_SZ /d "Courier New" /f

Set font size to 20 :

    REG ADD HKCU\Console /v FontSize /t REG_DWORD /d 20 /f

Enable quick edit if you like :

    REG ADD HKCU\Console /v QuickEdit /t REG_DWORD /d 1 /f

In a project I worked at we solved this problem by implement something we called 'Batch' requests. We defined a path /batch where we accepted json in the following format:

[  
   {
      path: '/docs',
      method: 'post',
      body: {
         doc_number: 1,
         binder: 1
      }
   },
   {
      path: '/docs',
      method: 'post',
      body: {
         doc_number: 5,
         binder: 8
      }
   },
   {
      path: '/docs',
      method: 'post',
      body: {
         doc_number: 6,
         binder: 3
      }
   },
]

The response have the status code 207 (Multi-Status) and looks like this:

[  
   {
      path: '/docs',
      method: 'post',
      body: {
         doc_number: 1,
         binder: 1
      }
      status: 200
   },
   {
      path: '/docs',
      method: 'post',
      body: {
         error: {
            msg: 'A document with doc_number 5 already exists'
            ...
         }
      },
      status: 409
   },
   {
      path: '/docs',
      method: 'post',
      body: {
         doc_number: 6,
         binder: 3
      },
      status: 200
   },
]

You could also add support for headers in this structure. We implemented something that proved useful which was variables to use between requests in a batch, meaning we can use the response from one request as input to another.

Facebook and Google have similar implementations:
https://developers.google.com/gmail/api/guides/batch
https://developers.facebook.com/docs/graph-api/making-multiple-requests

When you want to create or update a resource with the same call I would use either POST or PUT depending on the case. If the document already exist, do you want the entire document to be:

1. Replaced by the document you send in (i.e. missing properties in request will be removed and already existing overwritten)?
2. Merged with the document you send in (i.e. missing properties in request will not be removed and already existing properties will be overwritten)?

In case you want the behavior from alternative 1 you should use a POST and in case you want the behavior from alternative 2 you should use PUT.

http://restcookbook.com/HTTP%20Methods/put-vs-post/

As people already suggested you could also go for PATCH, but I prefer to keep API's simple and not use extra verbs if they are not needed.

In Java there is no good reason.

A couple of other answers have claimed that it's because you can accidentally make it assignment instead of equality. But in Java, you have to have a boolean in an if, so this:

if (o = null)

will not compile.

The only time this could matter in Java is if the variable is boolean:

int m1(boolean x)
{
    if (x = true)  // oops, assignment instead of equality

    ClassLoader cl = ClassLoader.getSystemClassLoader();

    URL[] urls = ((URLClassLoader)cl).getURLs();

    for(URL url: urls){
        System.out.println(url.getFile());
    }

Here are two ways to do the same thing, with or without jQuery:

// jquery way_x000D_
$(document).ready(function () {_x000D_
    _x000D_
  var json = [{"User_Name":"John Doe","score":"10","team":"1"},{"User_Name":"Jane Smith","score":"15","team":"2"},{"User_Name":"Chuck Berry","score":"12","team":"2"}];_x000D_
        _x000D_
  var tr;_x000D_
  for (var i = 0; i < json.length; i++) {_x000D_
    tr = $('<tr/>');_x000D_
    tr.append("<td>" + json[i].User_Name + "</td>");_x000D_
    tr.append("<td>" + json[i].score + "</td>");_x000D_
    tr.append("<td>" + json[i].team + "</td>");_x000D_
    $('table').first().append(tr);_x000D_
  }  _x000D_
});_x000D_
_x000D_
// without jquery_x000D_
function ready(){_x000D_
 var json = [{"User_Name":"John Doe","score":"10","team":"1"},{"User_Name":"Jane Smith","score":"15","team":"2"},{"User_Name":"Chuck Berry","score":"12","team":"2"}];_x000D_
  const table = document.getElementsByTagName('table')[1];_x000D_
  json.forEach((obj) => {_x000D_
      const row = table.insertRow(-1)_x000D_
    row.innerHTML = `_x000D_
      <td>${obj.User_Name}</td>_x000D_
      <td>${obj.score}</td>_x000D_
      <td>${obj.team}</td>_x000D_
    `;_x000D_
  });_x000D_
};_x000D_
_x000D_
if (document.attachEvent ? document.readyState === "complete" : document.readyState !== "loading"){_x000D_
  ready();_x000D_
} else {_x000D_
  document.addEventListener('DOMContentLoaded', ready);_x000D_
}

The above answer doesn't support observable interpolation (and cost me a lot of time trying to debug). The jsFiddle link in @BrandonTilley comment was the answer that worked for me, which I'll re-post here for preservation:

app.directive('backImg', function(){
    return function(scope, element, attrs){
        attrs.$observe('backImg', function(value) {
            element.css({
                'background-image': 'url(' + value +')',
                'background-size' : 'cover'
            });
        });
    };
});

Example using controller and template

Controller :

$scope.someID = ...;
/* 
The advantage of using directive will also work inside an ng-repeat :
someID can be inside an array of ID's 
*/

$scope.arrayOfIDs = [0,1,2,3];

Template :

Use in template like so :

<div back-img="img/service-sliders/{{someID}}/1.jpg"></div>

or like so :

<div ng-repeat="someID in arrayOfIDs" back-img="img/service-sliders/{{someID}}/1.jpg"></div>

You can use a $where. Just be aware it will be fairly slow (has to execute Javascript code on every record) so combine with indexed queries if you can.

db.T.find( { $where: function() { return this.Grade1 > this.Grade2 } } );

or more compact:

db.T.find( { $where : "this.Grade1 > this.Grade2" } );

UPD for mongodb v.3.6+

you can use $expr as described in recent answer

I had the same requirement and I have done this in following way.You also can try out this..

Use loadData method

web.loadData("<p style='text-align:center'><img class='aligncenter size-full wp-image-1607' title='' src="+movImage+" alt='' width='240px' height='180px' /></p><p><center><U><H2>"+movName+"("+movYear+")</H2></U></center></p><p><strong>Director : </strong>"+movDirector+"</p><p><strong>Producer : </strong>"+movProducer+"</p><p><strong>Character : </strong>"+movActedAs+"</p><p><strong>Summary : </strong>"+movAnecdotes+"</p><p><strong>Synopsis : </strong>"+movSynopsis+"</p>\n","text/html", "UTF-8");

movDirector movProducer like all are my string variable.

In short i retain custom styling for my url.

According to theory its the same things. Recursion and loop with the same O() complexity will work with the same theoretical speed, but of course real speed depends on language, compiler and processor. Example with power of number can be coded in iteration way with O(ln(n)):

  int power(int t, int k) {
  int res = 1;
  while (k) {
    if (k & 1) res *= t;
    t *= t;
    k >>= 1;
  }
  return res;
  }

<img style="width: 50%;" src="..." />

worked just fine for me ... Or am I missing something?

Edit: But see Shawn's caveat about accidentally upsizing.

Python has control flow statements instead of goto statements. One implementation of control flow is Python's while loop. You can give it a boolean condition (boolean values are either True or False in Python), and the loop will execute repeatedly until that condition becomes false. If you want to loop forever, all you have to do is start an infinite loop.

Be careful if you decide to run the following example code. Press Control+C in your shell while it is running if you ever want to kill the process. Note that the process must be in the foreground for this to work.

while True:
    # do stuff here
    pass

The line # do stuff here is just a comment. It doesn't execute anything. pass is just a placeholder in python that basically says "Hi, I'm a line of code, but skip me because I don't do anything."

Now let's say you want to repeatedly ask the user for input forever and ever, and only exit the program if the user inputs the character 'q' for quit.

You could do something like this:

while True:
    cmd = raw_input('Do you want to quit? Enter \'q\'!')
    if cmd == 'q':
        break

cmd will just store whatever the user inputs (the user will be prompted to type something and hit enter). If cmd stores just the letter 'q', the code will forcefully break out of its enclosing loop. The break statement lets you escape any kind of loop. Even an infinite one! It is extremely useful to learn if you ever want to program user applications which often run on infinite loops. If the user does not type exactly the letter 'q', the user will just be prompted repeatedly and infinitely until the process is forcefully killed or the user decides that he's had enough of this annoying program and just wants to quit.

Just to that :)

$('#form-edit').trigger("reset");
$('#form-edit').find('select').each(function(){
  $(this).change();
});

Depends on what you need the implementation to do well. Insertion order usually is not interesting so there is no need to maintain it so you can rearrange to get better performance.

For Maps it is usually HashMap and TreeMap that is used. By using hash codes, the entries can be put in small groups easy to search in. The TreeMap maintains a sorted order of the inserted entries at the cost of slower search, but easier to sort than a HashMap.

ulimit -c <value> sets the core file size limit on unix. By default, the core file size limit is 0. You can see your ulimit values with ulimit -a.

also, if you run your program from within gdb, it will halt your program on "segmentation violations" (SIGSEGV, generally when you accessed a piece of memory that you hadn't allocated) or you can set breakpoints.

ddd and nemiver are front-ends for gdb which make working with it much easier for the novice.

Remember: import UIKit

Swift:

UIDevice.currentDevice().name

Swift 3, 4, 5:

UIDevice.current.name

I had the exact same issue, I have kind of the same configuration as your exemple and I got it working by removing the line :

ssl on;

To quote the doc:

If HTTP and HTTPS servers are equal, a single server that handles both HTTP and HTTPS requests may be configured by deleting the directive “ssl on” and adding the ssl parameter for *:443 port

Try this:

public static List<ProductActivity> getCatalog(Resources res){
    if(catalog == null) {
        catalog.add(new Product("Dead or Alive", res
                .getDrawable(R.drawable.product_salmon),
                "Dead or Alive by Tom Clancy with Grant Blackwood", 29.99));
        catalog.add(new Product("Switch", res
                .getDrawable(R.drawable.switchbook),
                "Switch by Chip Heath and Dan Heath", 24.99));
        catalog.add(new Product("Watchmen", res
                .getDrawable(R.drawable.watchmen),
                "Watchmen by Alan Moore and Dave Gibbons", 14.99));
    }
}

sizeof tells you the size of a thing, not the number of elements in it. A more C++11 way to do what you are doing would be:

#include <array>
#include <string>
#include <iostream>

int main()
{
    std::array<std::string, 3> texts { "Apple", "Banana", "Orange" };
    for (auto& text : texts) {
        std::cout << text << '\n';
    }
    return 0;
}

Be sure to include the Key in the imports...

const {Builder, By, logging, until, Key} = require('selenium-webdriver');

searchInput.sendKeys(Key.ENTER) worked great for me

First of all, you are in a bad position now - having the task of writing tests for the code you did not originally create and without any changes - nightmare! Talk to your boss and explain, it is not possible to test the code without making it "testable". To make code testable you usually do some important changes;

Regarding private variables. You actually never should do that. Aiming to test private variables is the first sign that something wrong with the current design. Private variables are part of the implementation, tests should focus on behavior rather of implementation details.

Sometimes, private field are exposed to public access with some getter. I do that, but try to avoid as much as possible (mark in comments, like 'used for testing').

Since you have no possibility to change the code, I don't see possibility (I mean real possibility, not like Reflection hacks etc.) to check private variable.

An alternative solution, which is portable and with higher precision, available since C++11, is to use std::chrono.

Here is an example:

#include <iostream>
#include <chrono>
typedef std::chrono::high_resolution_clock Clock;

int main()
{
    auto t1 = Clock::now();
    auto t2 = Clock::now();
    std::cout << "Delta t2-t1: " 
              << std::chrono::duration_cast<std::chrono::nanoseconds>(t2 - t1).count()
              << " nanoseconds" << std::endl;
}

Running this on ideone.com gave me:

Delta t2-t1: 282 nanoseconds

Add items:

arr[0] = "product_1";
arr[1] = "100";
arr[2] = "10";
itm = new ListViewItem(arr);
listView1.Items.Add(itm);

Retrieve items:

productName = listView1.SelectedItems[0].SubItems[0].Text;
price = listView1.SelectedItems[0].SubItems[1].Text;
quantity = listView1.SelectedItems[0].SubItems[2].Text;

source code

I don't think this is the BEST solution, but it does appear to work. Instead of using the background color, I'm going to just embed an image of the background, position it relatively and then wrap the text in a child element and position it absolute - in the centre.

Updated 2018

Here is another variation on the Bootstrap 4.1 Navbar with multi-level dropdown. This one uses minimal CSS for the submenu, and can be re-positioned as desired:

https://www.codeply.com/go/nG6iMAmI2X

.dropdown-submenu {
  position: relative;
}

.dropdown-submenu .dropdown-menu {
  top: 0;
  left: 100%;
  margin-top: -1px;
}

jQuery to control display of submenus:

$('.dropdown-submenu > a').on("click", function(e) {
    var submenu = $(this);
    $('.dropdown-submenu .dropdown-menu').removeClass('show');
    submenu.next('.dropdown-menu').addClass('show');
    e.stopPropagation();
});

$('.dropdown').on("hidden.bs.dropdown", function() {
    // hide any open menus when parent closes
    $('.dropdown-menu.show').removeClass('show');
});

See this answer for activating the Bootstrap 4 submenus on hover

thanks to Vinay's code here is my code for when you can't have a listview inside a scrollview yet you need something like that

LayoutInflater li = LayoutInflater.from(this);

                RelativeLayout parent = (RelativeLayout) this.findViewById(R.id.relativeLayoutCliente);

                int recent = 0;

                for(Contatto contatto : contatti)
                {
                    View inflated_layout = li.inflate(R.layout.header_listview_contatti, layout, false);


                    inflated_layout.setId(contatto.getId());
                    ((TextView)inflated_layout.findViewById(R.id.textViewDescrizione)).setText(contatto.getDescrizione());
                    ((TextView)inflated_layout.findViewById(R.id.textViewIndirizzo)).setText(contatto.getIndirizzo());
                    ((TextView)inflated_layout.findViewById(R.id.textViewTelefono)).setText(contatto.getTelefono());
                    ((TextView)inflated_layout.findViewById(R.id.textViewMobile)).setText(contatto.getMobile());
                    ((TextView)inflated_layout.findViewById(R.id.textViewFax)).setText(contatto.getFax());
                    ((TextView)inflated_layout.findViewById(R.id.textViewEmail)).setText(contatto.getEmail());



                    RelativeLayout.LayoutParams relativeParams = new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);

                    if (recent == 0)
                    {
                        relativeParams.addRule(RelativeLayout.BELOW, R.id.headerListViewContatti);
                    }
                    else
                    {
                        relativeParams.addRule(RelativeLayout.BELOW, recent);
                    }
                    recent = inflated_layout.getId();

                    inflated_layout.setLayoutParams(relativeParams);
                    //inflated_layout.setLayoutParams( new RelativeLayout.LayoutParams(source));

                    parent.addView(inflated_layout);
                }

the relativeLayout stays inside a ScrollView so it all becomes scrollable :)

I know this is old but you should also try Zombie.js. A headless browser which is insanely fast and ideal for testing !

This is what I used.

$('#foo').popover({
    placement : 'bottom',
    title : 'Title',
    content : '<div id="popOverBox"><img src="http://i.telegraph.co.uk/multimedia/archive/01515/alGore_1515233c.jpg" /></div>'
});

and for the HTML

<b id="foo" rel="popover">text goes here</b>

For the first question I think answer would be:

<your DataFrame>.rename(columns={'count':'Total_Numbers'})

or

<your DataFrame>.columns = ['ID', 'Region', 'Total_Numbers']

As for second one I'd say the answer would be no. It's possible to use it like 'df.ID' because of python datamodel:

Attribute references are translated to lookups in this dictionary, e.g., m.x is equivalent to m.dict["x"]

Here's the default template for ListViewItem from Blend:

Default ListViewItem Template:

        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type ListViewItem}">
                    <Border x:Name="Bd" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Padding="{TemplateBinding Padding}" SnapsToDevicePixels="true">
                        <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
                    </Border>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsSelected" Value="true">
                            <Setter Property="Background" TargetName="Bd" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}"/>
                            <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.HighlightTextBrushKey}}"/>
                        </Trigger>
                        <MultiTrigger>
                            <MultiTrigger.Conditions>
                                <Condition Property="IsSelected" Value="true"/>
                                <Condition Property="Selector.IsSelectionActive" Value="false"/>
                            </MultiTrigger.Conditions>
                            <Setter Property="Background" TargetName="Bd" Value="{DynamicResource {x:Static SystemColors.InactiveSelectionHighlightBrushKey}}"/>
                            <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.InactiveSelectionHighlightTextBrushKey}}"/>
                        </MultiTrigger>
                        <Trigger Property="IsEnabled" Value="false">
                            <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.GrayTextBrushKey}}"/>
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>

Just remove the IsSelected Trigger and IsSelected/IsSelectionActive MultiTrigger, by adding the below code to your Style to replace the default template, and there will be no visual change when selected.

Solution to turn off the IsSelected property's visual changes:

    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type ListViewItem}">
                <Border x:Name="Bd" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Padding="{TemplateBinding Padding}" SnapsToDevicePixels="true">
                    <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
                </Border>
                <ControlTemplate.Triggers>
                    <Trigger Property="IsEnabled" Value="false">
                        <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.GrayTextBrushKey}}"/>
                    </Trigger>
                </ControlTemplate.Triggers>
            </ControlTemplate>
        </Setter.Value>
    </Setter>

The following formula determines if the text "CHECK" appears in cell C10. If it does not, the result is blank. If it does, the result is the work "CHECK".

=IF(ISERROR(FIND("CHECK",C10,1)),"","CHECK")

Like the following. It will make the user database owner.

EXEC sp_addrolemember N'db_owner', N'USerNAme'

In the comments of http://www.php.net/manual/de/function.mysql-db-name.php I found this one from ericpp % bigfoot.com:

If you just need the current database name, you can use MySQL's SELECT DATABASE() command:

<?php
function mysql_current_db() {
    $r = mysql_query("SELECT DATABASE()") or die(mysql_error());
    return mysql_result($r,0);
}
?>

Works only on Windows:

import winreg
import itertools

def serial_ports() -> list:
    path = 'HARDWARE\\DEVICEMAP\\SERIALCOMM'
    key = winreg.OpenKey(winreg.HKEY_LOCAL_MACHINE, path)

    ports = []
    for i in itertools.count():
        try:
            ports.append(winreg.EnumValue(key, i)[1])
        except EnvironmentError:
            break

    return ports

if __name__ == "__main__":
    ports = serial_ports()

I got you fam

override func viewDidLoad() {
    super.viewDidLoad() /*This ensures that our view loaded*/
    self.textField.delegate = self /*we select our text field that we want*/   
    self.view.addGestureRecognizer(UITapGestureRecognizer(target: self, action: Selector("dismissKeyboard")))
}

func dismissKeyboard(){ /*this is a void function*/
    textField.resignFirstResponder() /*This will dismiss our keyboard on tap*/
}

I was able to resolve this issue (as others mentioned in comments) by disabling "Enable Promotion of Distributed Transactions for RPC" (i.e. setting it to False):

As requested by @WonderWorker, you can do this via SQL script:

EXEC master.dbo.sp_serveroption
     @server = N'[mylinkedserver]',
     @optname = N'remote proc transaction promotion',
     @optvalue = N'false'

Why does this error occur?

Because you tried to access an element in a collection, using a numeric index that exceeds the collection's boundaries.

The first element in a collection is generally located at index 0. The last element is at index n-1, where n is the Size of the collection (the number of elements it contains). If you attempt to use a negative number as an index, or a number that is larger than Size-1, you're going to get an error.

How indexing arrays works

When you declare an array like this:

var array = new int[6]

The first and last elements in the array are

var firstElement = array[0];
var lastElement = array[5];

So when you write:

var element = array[5];

you are retrieving the sixth element in the array, not the fifth one.

Typically, you would loop over an array like this:

for (int index = 0; index < array.Length; index++)
{
    Console.WriteLine(array[index]);
}

This works, because the loop starts at zero, and ends at Length-1 because index is no longer less than Length.

This, however, will throw an exception:

for (int index = 0; index <= array.Length; index++)
{
    Console.WriteLine(array[index]);
}

Notice the <= there? index will now be out of range in the last loop iteration, because the loop thinks that Length is a valid index, but it is not.

How other collections work

Lists work the same way, except that you generally use Count instead of Length. They still start at zero, and end at Count - 1.

for (int index = 0; i < list.Count; index++)
{
    Console.WriteLine(list[index]);
} 

However, you can also iterate through a list using foreach, avoiding the whole problem of indexing entirely:

foreach (var element in list)
{
    Console.WriteLine(element.ToString());
}

You cannot index an element that hasn't been added to a collection yet.

var list = new List<string>();
list.Add("Zero");
list.Add("One");
list.Add("Two");
Console.WriteLine(list[3]);  // Throws exception.

A "sort merge" join is performed by sorting the two data sets to be joined according to the join keys and then merging them together. The merge is very cheap, but the sort can be prohibitively expensive especially if the sort spills to disk. The cost of the sort can be lowered if one of the data sets can be accessed in sorted order via an index, although accessing a high proportion of blocks of a table via an index scan can also be very expensive in comparison to a full table scan.

A hash join is performed by hashing one data set into memory based on join columns and reading the other one and probing the hash table for matches. The hash join is very low cost when the hash table can be held entirely in memory, with the total cost amounting to very little more than the cost of reading the data sets. The cost rises if the hash table has to be spilled to disk in a one-pass sort, and rises considerably for a multipass sort.

(In pre-10g, outer joins from a large to a small table were problematic performance-wise, as the optimiser could not resolve the need to access the smaller table first for a hash join, but the larger table first for an outer join. Consequently hash joins were not available in this situation).

The cost of a hash join can be reduced by partitioning both tables on the join key(s). This allows the optimiser to infer that rows from a partition in one table will only find a match in a particular partition of the other table, and for tables having n partitions the hash join is executed as n independent hash joins. This has the following effects:

1. The size of each hash table is reduced, hence reducing the maximum amount of memory required and potentially removing the need for the operation to require temporary disk space.
2. For parallel query operations the amount of inter-process messaging is vastly reduced, reducing CPU usage and improving performance, as each hash join can be performed by one pair of PQ processes.
3. For non-parallel query operations the memory requirement is reduced by a factor of n, and the first rows are projected from the query earlier.

You should note that hash joins can only be used for equi-joins, but merge joins are more flexible.

In general, if you are joining large amounts of data in an equi-join then a hash join is going to be a better bet.

This topic is very well covered in the documentation.

I need to somehow query Google and ask: Is this access token valid for [email protected]?

No. All you need is request standard login with Federated Login for Google Account Users from your API domain. And only after that you could compare "persistent user ID" with one you have from 'public interface'.

The value of realm is used on the Google Federated Login page to identify the requesting site to the user. It is also used to determine the value of the persistent user ID returned by Google.

So you need be from same domain as 'public interface'.

And do not forget that user needs to be sure that your API could be trusted ;) So Google will ask user if it allows you to check for his identity.

public void Letters(JTextField a) {
    a.addKeyListener(new KeyAdapter() {
        @Override
        public void keyTyped(java.awt.event.KeyEvent e) {
            char c = e.getKeyChar();
            if (Character.isDigit(c)) {
                e.consume();
            }
            if (Character.isLetter(c)) {
                e.setKeyChar(Character.toUpperCase(c));
            }
        }
    });
}

public void Numbers(JTextField a) {
    a.addKeyListener(new KeyAdapter() {
        @Override
        public void keyTyped(java.awt.event.KeyEvent e) {
            char c = e.getKeyChar();
            if (!Character.isDigit(c)) {
                e.consume();
            }
        }
    });
}

public void Caracters(final JTextField a, final int lim) {
    a.addKeyListener(new KeyAdapter() {
        @Override
        public void keyTyped(java.awt.event.KeyEvent ke) {
            if (a.getText().length() == lim) {
                ke.consume();
            }
        }
    });
}

This is the easiest way to do this.

fin = open("a.txt")
f = open("file.txt", "wt")
for line in fin:
    f.write( line.replace('foo', 'bar') )
fin.close()
f.close()

I hope it will work for you.

Out of all the answers above nothing worked for me. I had to manually change the users password in the database and it suddenly worked.

psql -U postgres -d postgres -c "alter user produser with password 'produser';"

I used the following settings:

pg_hba.conf

local   all             all                                     peer
# IPv4 local connections:
host    all             all             127.0.0.1/32            password  
# IPv6 local connections:
host    all             all             ::1/128                 password

Connection is successful finally for the following command:

psql -U produser -d dbname -h localhost -W 

Use Python 2.7, is has more 3rd party libs at the moment. (Edit: see below).

I recommend you using the stdlib module urllib2, it will allow you to comfortably get web resources. Example:

import urllib2

response = urllib2.urlopen("http://google.de")
page_source = response.read()

For parsing the code, have a look at BeautifulSoup.

BTW: what exactly do you want to do:

Just for background, I need to download a page and replace any img with ones I have

Edit: It's 2014 now, most of the important libraries have been ported, and you should definitely use Python 3 if you can. python-requests is a very nice high-level library which is easier to use than urllib2.

If you want to remove/clean all the values from local storage than use

localStorage.clear();

And if you want to remove the specific item from local storage than use the following code

localStorage.removeItem(key);

Sound like you just have an issue with the path. Include the full path, if you use backslashes they need to be escaped: "C:\\folder\\folder\\Desktop\\file.csv" or "C:/folder/folder/Desktop/file.csv".

myfile = read.csv("C:/folder/folder/Desktop/file.csv")  # or read.table()

It may also be wise to avoid spaces and symbols in your file names, though I'm fairly certain spaces are OK.

I didn't find this solution here. It removes all of it using the cowplot package:

library(cowplot)

p + theme_nothing() +
theme(legend.position="none") +
scale_x_continuous(expand=c(0,0)) +
scale_y_continuous(expand=c(0,0)) +
labs(x = NULL, y = NULL)

Just noticed that the same thing can be accomplished using theme.void() like this:

p + theme_void() +
theme(legend.position="none") +
scale_x_continuous(expand=c(0,0)) +
scale_y_continuous(expand=c(0,0)) +
labs(x = NULL, y = NULL)

Break out the LIKE clauses into 2 separate statements, i.e.:

(fieldname1 LIKE '%this%' or fieldname1 LIKE '%that%' ) and something=else

If you are creating a div and trying to add a title to it.

Try

var myDiv= document.createElement("div");
myDiv.setAttribute('title','mytitle');

Here's a slightly different approach (I don't think the other answers do this). I'm not sure whether I love it or hate it, but it works!

export function addDaySuffix(day: number) { 
  const suffixes =
      '  stndrdthththththththththththththththththstndrdthththththththst';
    const startIndex = day * 2;

    return `${day}${suffixes.substring(startIndex, startIndex + 2)}`;
  }

Assuming your dataframe is mydf:

mydf$task <- factor(mydf$task, levels = c("up", "down", "left", "right", "front", "back"))

private void checkBox1_CheckedChanged(object sender, EventArgs e)
{
    if (checkBoxImage.Checked)
    {
        groupBoxImage.Show();
    }
    else if (!checkBoxImage.Checked)
    {
        groupBoxImage.Hide(); 
    }
}

Re-enabling the Application Experience service of Windows has fixed that kind of problems for me.

See the following links:

• Visual Studio output file permissions?
• Under which circumstances does the System process (PID 4) retain an open file handle?

I had the problem using Visual Studio 2008, 2010 and 2013 with Windows 7 64-bit.

Here is another possible way:

void main() {
  var s1 = Singleton.instance;
  s1.somedata = 123;
  var s2 = Singleton.instance;
  print(s2.somedata); // 123
  print(identical(s1, s2));  // true
  print(s1 == s2); // true
  //var s3 = new Singleton(); //produces a warning re missing default constructor and breaks on execution
}

class Singleton {
  static final Singleton _singleton = new Singleton._internal();
  Singleton._internal();
  static Singleton get instance => _singleton;
  var somedata;
}

I think all you need to do for your function is just add PtrSafe: i.e. the first line of your first function should look like this:

Private Declare PtrSafe Function swe_azalt Lib "swedll32.dll" ......

I had similar problem when importing phone number data from excel to mysql database. So a simple trick without the need to identify the length of the phone number (because the length of the phone numbers varied in my data):

UPDATE table SET phone_num = concat('0', phone_num) 

I just concated 0 in front of the phone_num.

It's also important to note that not all supported languages compair consistently with thrift or protobuf. At this point it's a matter of the modules implementation in addition to the underlying serialization. Take care to check benchmarks for whatever language you plan to use.

Specifying the absolute path to the library should work fine:

g++ /my/dir/libfoo.so.0  ...

Did you remember to remove the -lfoo once you added the absolute path?

print [x for x in range(2,100) if not [t for t in range(2,x) if not x%t]]

See ?substr

R> substr(a, 1, 4)
[1] "left"

Some practical examples, somewhat connected to large scale development where Gerrit is used for review and delivery integration:

I merge when I uplift my feature branch to a fresh remote master. This gives minimal uplift work and it's easy to follow the history of the feature development in for example gitk.

git fetch
git checkout origin/my_feature
git merge origin/master
git commit
git push origin HEAD:refs/for/my_feature

I merge when I prepare a delivery commit.

git fetch
git checkout origin/master
git merge --squash origin/my_feature
git commit
git push origin HEAD:refs/for/master

I rebase when my delivery commit fails integration for whatever reason, and I need to update it towards a fresh remote master.

git fetch
git fetch <gerrit link>
git checkout FETCH_HEAD

SQL is a declarative language, not a procedural language. That is, you construct a SQL statement to describe the results that you want. You are not telling the SQL engine how to do the work.

As a general rule, it is a good idea to let the SQL engine and SQL optimizer find the best query plan. There are many person-years of effort that go into developing a SQL engine, so let the engineers do what they know how to do.

Of course, there are situations where the query plan is not optimal. Then you want to use query hints, restructure the query, update statistics, use temporary tables, add indexes, and so on to get better performance.

As for your question. The performance of CTEs and subqueries should, in theory, be the same since both provide the same information to the query optimizer. One difference is that a CTE used more than once could be easily identified and calculated once. The results could then be stored and read multiple times. Unfortunately, SQL Server does not seem to take advantage of this basic optimization method (you might call this common subquery elimination).

Temporary tables are a different matter, because you are providing more guidance on how the query should be run. One major difference is that the optimizer can use statistics from the temporary table to establish its query plan. This can result in performance gains. Also, if you have a complicated CTE (subquery) that is used more than once, then storing it in a temporary table will often give a performance boost. The query is executed only once.

The answer to your question is that you need to play around to get the performance you expect, particularly for complex queries that are run on a regular basis. In an ideal world, the query optimizer would find the perfect execution path. Although it often does, you may be able to find a way to get better performance.

This is very annoying and I expect future versions of C# will address this need. I find the easiest work around to be either use a different data structure type or rename the "items" for your sanity and for the sanity of others reading your code.

Tuple<ApiResource, JSendResponseStatus> result = await SendApiRequest();
ApiResource apiResource = result.Item1;
JSendResponseStatus jSendStatus = result.Item2;

you can use something like this....div container

<script type="text/javascript">
function hide(){
document.getElementById("test").innerHTML.style.display="none";
}
</script>
<div id="test">
<form method="post" >

<table width="60%" border="0" cellspacing="2" cellpadding="2"  >
  <tr style="background:url(../images/nav.png) repeat-x; color:#fff; font-weight:bold" align="center">
    <td>Ample Id</td>
    <td>Find</td>
  </tr>

  <tr align="center" bgcolor="#E8F8FF" style="color:#006" >
    <td><input type="text" name="ampid" id="ampid" value="<?php echo $_POST['ampid'];?>" /></td>
   <td><input type="image" src="../images/btnFind.png" id="find" name="find" onclick="javascript:hide();"/></td>
   </tr>

</table>

</form>
</div>

it should be enough to mark your aspect method like this:

@After("@annotation(com.marcot.CommitTransaction)")
    public void after() {

have a look at this for a step by step guide on this.

you have to compare in between new values, that's the trick, think always in the previous (the 2nd largest) should be between the max and the previous max before, that's the one!!!!

def secondLargest(lista):
    max_number   = 0
    prev_number  = 0

    for i in range(0, len(lista)):

        if lista[i] > max_number:
            prev_number = max_number
            max_number  = lista[i]
        elif lista[i] > prev_number and lista[i] < max_number:
            prev_number = lista[i]

    return prev_number

Use double quotes:

$i = 1;
echo "
<p class=\"paragraph$i\">
</p>
";
++i;

Repository is more abstract domain oriented term that is part of Domain Driven Design, it is part of your domain design and a common language, DAO is a technical abstraction for data access technology, repository is concerns only with managing existing data and factories for creation of data.

add a repository,

sudo apt-add-repository ppa:maarten-fonville/android-studio
sudo apt-get update

Then install using the command below:

sudo apt-get install android-studio

Another awk variant:

#!/usr/bin/awk -f
# usage:
# awk -f randomize_lines.awk lines.txt
# usage after "chmod +x randomize_lines.awk":
# randomize_lines.awk lines.txt

BEGIN {
  FS = "\n";
  srand();
}

{
  lines[ rand()] = $0;
}

END {
  for( k in lines ){
    print lines[k];
  }
}

The answer to your question is:

app.use(function(req, res) {
    res.status(404).end('error');
});

And there is a great article about why it is the best way here.

popstate event:

The popstate event is fired when the active history entry changes. [...] The popstate event is only triggered by doing a browser action such as a click on the back button (or calling history.back() in JavaScript)

So, listening to popstate event and sending a popstate event when using history.pushState() should be enough to take action on href change:

window.addEventListener('popstate', listener);

const pushUrl = (href) => {
  history.pushState({}, '', href);
  window.dispatchEvent(new Event('popstate'));
};

This error appears to happen when .mof files (Managed Object Format (MOF)) don’t get installed and registered correctly during set-up. To resolve this issue, I executed the following mofcomp command in command prompt to re-register the *.mof files:

mofcomp.exe "C:\Program Files (x86)\Microsoft SQL Server\100\Shared\sqlmgmproviderxpsp2up.mof"

This one worked for me

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

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

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

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

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

i also had the same problem in one of my project. I resolved it by adding some following parameters in the theme provided to the splash screen.

<item name="android:windowFullscreen">true</item>
<item name="android:windowContentOverlay">@null</item>
<item name="android:windowIsTranslucent">true</item>

You can find the reason and resolution in this blog post written by me. Hope it helps.

I wanted to check if a port is open on one of our linux test servers. I was able to do that by trying to connect with telnet from my dev machine to the test server. On you dev machine try to run:

$ telnet test2.host.com 8080
Trying 05.066.137.184...
Connected to test2.host.com

In this example I want to check if port 8080 is open on host test2.host.com

In Core 2.2 Razor pages this syntax works:

    <button type="submit" name="Submit">Save</button>
    <button type="submit" name="Cancel">Cancel</button>
public async Task<IActionResult> OnPostAsync()
{
    if (!ModelState.IsValid)
        return Page();
    var sub = Request.Form["Submit"];
    var can = Request.Form["Cancel"];
    if (sub.Count > 0)
       {
       .......

(PartlyStolen from ServerFault)

I think that both are functionally the same, but they simply have different authors, and the one is simply named more appropriately than the other.

Here is a quick backgrounder in naming conventions (for those unfamiliar), which explains the frustration by the question asker: For many *nix applications, the piece that does the backend work is called a "daemon" (think "service" in Windows-land), while the interface or client application is what you use to control or access the daemon. The daemon is most often named the same as the client, with the letter "d" appended to it. For example "imap" would be a client that connects to the "imapd" daemon.

This naming convention is clearly being adhered to by memcache when you read the introduction to the memcache module (notice the distinction between memcache and memcached in this excerpt):

Memcache module provides handy procedural and object oriented interface to memcached, highly effective caching daemon, which was especially designed to decrease database load in dynamic web applications.

The Memcache module also provides a session handler (memcache).

More information about memcached can be found at » http://www.danga.com/memcached/.

The frustration here is caused by the author of the PHP extension which was badly named memcached, since it shares the same name as the actual daemon called memcached. Notice also that in the introduction to memcached (the php module), it makes mention of libmemcached, which is the shared library (or API) that is used by the module to access the memcached daemon:

memcached is a high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic web applications by alleviating database load.

This extension uses libmemcached library to provide API for communicating with memcached servers. It also provides a session handler (memcached).

Information about libmemcached can be found at » http://tangent.org/552/libmemcached.html.

You want to check if an object is NULL/empty. Being NULL and empty are not the same. Like Justin and Brian have already mentioned, in C++ NULL is an assignment you'd typically associate with pointers. You can overload operator= perhaps, but think it through real well if you actually want to do this. Couple of other things:

1. In C++ NULL pointer is very different to pointer pointing to an 'empty' object.
2. Why not have a bool IsEmpty() method that returns true if an object's variables are reset to some default state? Guess that might bypass the NULL usage.
3. Having something like A* p = new A; ... p = NULL; is bad (no delete p) unless you can ensure your code will be garbage collected. If anything, this'd lead to memory leaks and with several such leaks there's good chance you'd have slow code.
4. You may want to do this class Null {}; Null _NULL; and then overload operator= and operator!= of other classes depending on your situation.

Perhaps you should post us some details about the context to help you better with option 4.

Arpan

Usually not with grep, but rather with sed -i 's/string_to_find/another_string/g' or perl -i.bak -pe 's/string_to_find/another_string/g'.

The reject actually takes one parameter: that's the exception that occurred in your code that caused the promise to be rejected. So, when you call reject() the exception value is undefined, hence the "undefined" part in the error that you get.

You do not show the code that uses the promise, but I reckon it is something like this:

var promise = doSth();
promise.then(function() { doSthHere(); });

Try adding an empty failure call, like this:

promise.then(function() { doSthHere(); }, function() {});

This will prevent the error to appear.

However, I would consider calling reject only in case of an actual error, and also... having empty exception handlers isn't the best programming practice.

i tried that successful.

scrollView.postDelayed(new Runnable() {
    @Override
    public void run() {
        scrollView.smoothScrollTo(0, scrollView.getHeight());
    }
}, 1000);

strtotime('-1 day', strtotime($date))

This returns the number of difference in seconds of the given date and the $date.so you are getting wrong result .

Suppose $date is todays date and -1 day means it returns -86400 as the difference and the when you try using date you will get 1969-12-31 Unix timestamp start date.

If you are trying to use AngularJs 1.6.6 as of 21/10/2017 the following parameter works as .success and has been depleted. The .then() method takes two arguments: a response and an error callback which will be called with a response object.

 $scope.login = function () {
        $scope.btntext = "Please wait...!";
        $http({
            method: "POST",
            url: '/Home/userlogin', // link UserLogin with HomeController 
            data: $scope.user
         }).then(function (response) {
            console.log("Result value is : " + parseInt(response));
            data = response.data;
            $scope.btntext = 'Login';
            if (data == 1) {
                window.location.href = '/Home/dashboard';
             }
            else {
            alert(data);
        }
        }, function (error) {

        alert("Failed Login");
        });

The above snipit works for a login page.

Seems to work fine.

If you have an empty BEGIN ... END block you might see

Msg 102, Level 15, State 1, Line 10 Incorrect syntax near 'END'.

That only means that an undefined column or parameter name was detected. The errror that DB2 gives should point what that may be:

DB2 SQL Error: SQLCODE=-206, SQLSTATE=42703, SQLERRMC=[THE_UNDEFINED_COLUMN_OR_PARAMETER_NAME], DRIVER=4.8.87

Double check your table definition. Maybe you just missed adding something.

I also tried google-ing this problem and saw this:

Based on Tomasz Nurkiewiczs answer, the "problem" is that typescript is typesafe. :) So the document.getElementById() returns the type HTMLElement which does not contain a value property. The subtype HTMLInputElement does however contain the value property.

So a solution is to cast the result of getElementById() to HTMLInputElement like this:

var inputValue = (<HTMLInputElement>document.getElementById(elementId)).value;

<> is the casting operator in typescript. See the question TypeScript: casting HTMLElement.

The resulting javascript from the line above looks like this:

inputValue = (document.getElementById(elementId)).value;

i.e. containing no type information.

Adding Quotes

I started using this quick and dirty function in my .vimrc:

vnoremap q <esc>:call QuickWrap("'")<cr>
vnoremap Q <esc>:call QuickWrap('"')<cr>

function! QuickWrap(wrapper)
  let l:w = a:wrapper
  let l:inside_or_around = (&selection == 'exclusive') ? ('i') : ('a')
  normal `>
  execute "normal " . inside_or_around . escape(w, '\')
  normal `<
  execute "normal i" . escape(w, '\')
  normal `<
endfunction

So now, I visually select whatever I want (typically via viw - visually select inside word) in quotes and press Q for double quotes, or press q for single quotes.

Removing Quotes

vnoremap s <esc>:call StripWrap()<cr>

function! StripWrap()
  normal `>x`<x
endfunction

I use vim-textobj-quotes so that vim treats quotes as a text objects. This means I can do vaq (visually select around quotes. This finds the nearest quotes and visually selects them. (This is optional, you can just do something like f"vww). Then I press s to strip the quotes from the selection.

Changing Quotes

KISS. I remove quotes then add quotes. For example, to replace single quotes with double quotes, I would perform the steps: 1. remove single quotes: vaqs, 2. add new quotes: vwQ.

To find the version of the subversion REPOSITORY you can:

1. Look to the repository on the web and on the bottom of the page it will say something like:
   "Powered by Subversion version 1.5.2 (r32768)."
2. From the command line: <insert curl, grep oneliner here>

If not displayed, view source of the page

<svn version="1.6.13 (r1002816)" href="http://subversion.tigris.org/"> 

Now for the subversion CLIENT:

svn --version

will suffice

You should initialize yours recordings. You are passing to adapter null

ArrayList<String> recordings = null; //You are passing this null

data = pd.DataFrame({"a":[1,2,3,34],"b":[5,6,7,8]})
new_data = pd.melt(data)
new_data.set_index("variable", inplace=True)

This gives a dataframe with index as column name of data and all data are present in "values" column

As soon as you're displaying content from another domain, you're basically trusting that domain not to serve-up malware.

There's nothing wrong with iframes per se. If you control the content of the iframe, they're perfectly safe.

@Nanocom's answer works for me. It may be that lines have to be at the end, or could be because has to be after of some the bean class like this:

<bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping" />
<bean class="org.springframework.web.servlet.resource.ResourceHttpRequestHandler" />    

<mvc:resources mapping="/resources/**" 
               location="/resources/" 
               cache-period="10000" />

I saw different answers and came up with a class helper:

using System;
using System.Web.Mvc;

namespace MyMvcApp.Helpers {
    public class LocationHelper {
        public static bool IsCurrentControllerAndAction(string controllerName, string actionName, ViewContext viewContext) {
            bool result = false;
            string normalizedControllerName = controllerName.EndsWith("Controller") ? controllerName : String.Format("{0}Controller", controllerName);

            if(viewContext == null) return false;
            if(String.IsNullOrEmpty(actionName)) return false;

            if (viewContext.Controller.GetType().Name.Equals(normalizedControllerName, StringComparison.InvariantCultureIgnoreCase) &&
                viewContext.Controller.ValueProvider.GetValue("action").AttemptedValue.Equals(actionName, StringComparison.InvariantCultureIgnoreCase)) {
                result = true;
            }

            return result;
        }
    }
}

So in View (or master/layout) you can use it like so (Razor syntax):

            <div id="menucontainer">

                <ul id="menu">
                    <li @if(MyMvcApp.Helpers.LocationHelper.IsCurrentControllerAndAction("home", "index", ViewContext)) {
                            @:class="selected"
                        }>@Html.ActionLink("Home", "Index", "Home")</li>
                    <li @if(MyMvcApp.Helpers.LocationHelper.IsCurrentControllerAndAction("account","logon", ViewContext)) {
                            @:class="selected"
                        }>@Html.ActionLink("Logon", "Logon", "Account")</li>
                    <li @if(MyMvcApp.Helpers.LocationHelper.IsCurrentControllerAndAction("home","about", ViewContext)) {
                            @:class="selected"
                        }>@Html.ActionLink("About", "About", "Home")</li>
                </ul>

            </div>

Hope it helps.

if your image is purely decorative, then it might be a more semantic solution to use it as a background-image. You can then specify the position of the background

background-position: center center;

If it is not decorative and constitutes valuable information then the img tag is justified. What you need to do in such case is style the containing div with the following properties:

div{
    display: table-cell; vertical-align: middle 
}

For Using the_content() functions (for displaying the main content of the page)

$content = get_the_content();

$excerpt= get_the_excerpt();

echo substr($excerpt, 0, 100);

Putting the call to mysql_insert_id() inside a transaction, should do it:

mysql_query('BEGIN');
// Whatever code that does the insert here.
$id = mysql_insert_id();
mysql_query('COMMIT');
// Stuff with $id.

When you say:

 #include <cstring>

the g++ compiler should put the <string.h> declarations it itself includes into the std:: AND the global namespaces. It looks for some reason as if it is not doing that. Try replacing one instance of strcpy with std::strcpy and see if that fixes the problem.

Hope this will work for someone out there
I was facing the same issue! I had 2 sdks, named as sdk and sdk1. It was default linked to sdk but the working one was sdk1. So I went to Environment Varaible and added ANDROID_HOME and path of the sdk1, i.e. in my case was C:\Users\tripa_000\AppData\Local\Android\sdk1 , and it solved my problem!

You are getting undefined because you probably have the components outside React Router.

Remember that you need to make sure that the component from which you are calling this.props.location is inside a <Route /> component such as this:

<Route path="/dashboard" component={Dashboard} />

Then inside the Dashboard component, you have access to this.props.location...

On Windows, you can use WMI (home page, cheeseshop):

Here's an example that makes sure that the body has minimum height of the device screen height and also hides the scroll bar. It uses DOMSubtreeModified event, but makes the check only every 400ms, to avoid performance loss.

var page_size_check = null, q_body;
(q_body = $('#body')).bind('DOMSubtreeModified', function() {
  if (page_size_check === null) {
    return;
  }
  page_size_check = setTimeout(function() {
    q_body.css('height', '');
    if (q_body.height() < window.innerHeight) {
      q_body.css('height', window.innerHeight + 'px');
    }
    if (!(window.pageYOffset > 1)) {
      window.scrollTo(0, 1);
    }
    page_size_check = null;
  }, 400);
});

It's valid in C for historical reasons. C traditionally specified that the type of a string literal was char * rather than const char *, although it qualified it by saying that you're not actually allowed to modify it.

When you use a cast, you're essentially telling the compiler that you know better than the default type matching rules, and it makes the assignment OK.

            .otherwise({template:'Not Found'});
    }
   //aboutUs controller 
    app.controller('aboutCtrl',function($routeParams){
          $scope.paramOnePrint=$routeParams.paramOne;
          $scope.paramTwoPrint=$routeParams.paramTwo;
    });

in index.html

<a ng-href="#/about/firstParam/secondParam">About</a>

firstParam and secondParam can be anything according to your needs.

Use jQuery.one()

Attach a handler to an event for the elements. The handler is executed at most once per element per event type

$('form').one('submit', function(e) {
    e.preventDefault();
    // do your things ...

    // and when you done:
    $(this).submit();
});

The use of one prevent also infinite loop because this custom submit event is detatched after the first submit.

I was having multiple date formats into json, and was extracting csv with universal format. I looked multiple places, tried different ways, but at the end I'm able to convert with the following simple code.

private String getDate(String anyDateFormattedString) {
    @SuppressWarnings("deprecation")
    Date date = new Date(anyDateFormattedString);
    SimpleDateFormat dateFormat = new SimpleDateFormat(yourDesiredDateFormat);
        String convertedDate = dateFormat.format(date);
    return convertedDate;
}

Vertically centered Add .modal-dialog-centered to .modal-dialog to vertically center the modal

Launch demo modal

<!-- Modal -->
<div class="modal fade" id="exampleModalCenter" tabindex="-1" role="dialog" aria-labelledby="exampleModalCenterTitle" aria-hidden="true">
  <div class="modal-dialog modal-dialog-centered" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalCenterTitle">Modal title</h5>
        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
          <span aria-hidden="true">&times;</span>
        </button>
      </div>
      <div class="modal-body">
        ...
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>

With Kotlin you can do that in just 2 lines

Change color values in the array

                  val gradientDrawable = GradientDrawable(
                        GradientDrawable.Orientation.TOP_BOTTOM,
                        intArrayOf(Color.parseColor("#008000"),
                                   Color.parseColor("#ADFF2F"))
                    );
                    gradientDrawable.cornerRadius = 0f;

                   //Set Gradient
                   linearLayout.setBackground(gradientDrawable);

Result

In my case, I forgot to add MatDialogModule to imports in a child module.

For removing older versions of all installed gems, following 2 commands are useful:

 gem cleanup --dryrun

Above command will preview what gems are going to be removed.

 gem cleanup

Above command will actually remove them.

It allows you to access all subclasses through a common parent interface. This is beneficial for running common operations available on all subclasses. A better example is needed:

public class Shape
{
  private int x, y;
  public void draw();
}

public class Rectangle extends Shape
{ 
  public void draw();
  public void doRectangleAction();
}

Now if you have:

List<Shape> myShapes = new ArrayList<Shape>();

You can reference every item in the list as a Shape, you don't have to worry if it is a Rectangle or some other type like let's say Circle. You can treat them all the same; you can draw all of them. You can't call doRectangleAction because you don't know if the Shape is really a rectangle.

This is a trade of you make between treating objects in a generic fashion and treating the specifically.

Really I think you need to read more about OOP. A good book should help: http://www.amazon.com/Design-Patterns-Explained-Perspective-Object-Oriented/dp/0201715945

From my understanding, the currently accepted answer only changes the order of the factor levels, not the actual labels (i.e., how the levels of the factor are called). To illustrate the difference between levels and labels, consider the following example:

Turn cyl into factor (specifying levels would not be necessary as they are coded in alphanumeric order):

    mtcars2 <- mtcars %>% mutate(cyl = factor(cyl, levels = c(4, 6, 8))) 
    mtcars2$cyl[1:5]
    #[1] 6 6 4 6 8
    #Levels: 4 6 8

Change the order of levels (but not the labels itself: cyl is still the same column)

    mtcars3 <- mtcars2 %>% mutate(cyl = factor(cyl, levels = c(8, 6, 4))) 
    mtcars3$cyl[1:5]
    #[1] 6 6 4 6 8
    #Levels: 8 6 4
    all(mtcars3$cyl==mtcars2$cyl)
    #[1] TRUE

Assign new labels to cyl The order of the labels was: c(8, 6, 4), hence we specify new labels as follows:

    mtcars4 <- mtcars3 %>% mutate(cyl = factor(cyl, labels = c("new_value_for_8", 
                                                               "new_value_for_6", 
                                                               "new_value_for_4" )))
    mtcars4$cyl[1:5]
    #[1] new_value_for_6 new_value_for_6 new_value_for_4 new_value_for_6 new_value_for_8
    #Levels: new_value_for_8 new_value_for_6 new_value_for_4

Note how this column differs from our first columns:

    all(as.character(mtcars4$cyl)!=mtcars3$cyl) 
    #[1] TRUE 
    #Note: TRUE here indicates that all values are unequal because I used != instead of ==
    #as.character() was required as the levels were numeric and thus not comparable to a character vector

More details:

If we were to change the levels of cyl using mtcars2 instead of mtcars3, we would need to specify the labels differently to get the same result. The order of labels for mtcars2 was: c(4, 6, 8), hence we specify new labels as follows

    #change labels of mtcars2 (order used to be: c(4, 6, 8)
    mtcars5 <- mtcars2 %>% mutate(cyl = factor(cyl, labels = c("new_value_for_4", 
                                                               "new_value_for_6", 
                                                               "new_value_for_8" )))

Unlike mtcars3$cyl and mtcars4$cyl, the labels of mtcars4$cyl and mtcars5$cyl are thus identical, even though their levels have a different order.

    mtcars4$cyl[1:5]
    #[1] new_value_for_6 new_value_for_6 new_value_for_4 new_value_for_6 new_value_for_8
    #Levels: new_value_for_8 new_value_for_6 new_value_for_4

    mtcars5$cyl[1:5]
    #[1] new_value_for_6 new_value_for_6 new_value_for_4 new_value_for_6 new_value_for_8
    #Levels: new_value_for_4 new_value_for_6 new_value_for_8

    all(mtcars4$cyl==mtcars5$cyl)
    #[1] TRUE

    levels(mtcars4$cyl) == levels(mtcars5$cyl)
    #1] FALSE  TRUE FALSE

I would highly recommend a different approach.

It's possible if you REALLY want to do it, but it costs a lot of memory and is also slow. It might not work if you have an older phone and a big bitmap. You could just pass it as an extra, for example intent.putExtra("data", bitmap). A Bitmap implements Parcelable, so you can put it in an extra. Likewise, a bundle has putParcelable.

If you want to pass it inbetween activities, I would store it in a file. That's more efficient, and less work for you. You can create private files in your data folder using MODE_PRIVATE that are not accessible to any other app.

You might want to check out Remy Sharp's recent article on fixed floating elements at jQuery for Designers, which has a nice video and writeup on how to apply this effect in client script

You could also just run

go build

in your project folder myproject/go/src/myprog

Then you can just type

./myprog

to run your app

Answer : document.body.scroll = 'no';

My answer is inspired on my own working experience, and mostly in the book Two Scoops of Django which I highly recommend, and where you can find a more detailed explanation of everything. I just will answer some of the points, and any improvement or correction will be welcomed. But there also can be more correct manners to achieve the same purpose.

Projects
I have a main folder in my personal directory where I maintain all the projects where I am working on.

Source Files
I personally use the django project root as repository root of my projects. But in the book is recommended to separate both things. I think that this is a better approach, so I hope to start making the change progressively on my projects.

project_repository_folder/
    .gitignore
    Makefile
    LICENSE.rst
    docs/
    README.rst
    requirements.txt
    project_folder/
        manage.py
        media/
        app-1/
        app-2/
        ...
        app-n/
        static/
        templates/
        project/
            __init__.py
            settings/
                __init__.py
                base.py
                dev.py
                local.py
                test.py
                production.py
            ulrs.py
            wsgi.py

Repository
Git or Mercurial seem to be the most popular version control systems among Django developers. And the most popular hosting services for backups GitHub and Bitbucket.

Virtual Environment
I use virtualenv and virtualenvwrapper. After installing the second one, you need to set up your working directory. Mine is on my /home/envs directory, as it is recommended on virtualenvwrapper installation guide. But I don't think the most important thing is where is it placed. The most important thing when working with virtual environments is keeping requirements.txt file up to date.

pip freeze -l > requirements.txt

Database

You can use the following command to update any module with its dependencies

composer update vendor-name/module-name --with-dependencies

git log's pickaxe will find commits with changes including "word" with git log -Sword

I have done this in the past, and have always used this:

  With Me.RecordsetClone
    .MoveFirst
    Do Until .EOF
      If Me.Dirty Then
         Me.Dirty = False
      End If
      .MoveNext
      Me.Bookmark = .Bookmark
    Loop
  End With

Some people would use the form's Recordset, which doesn't require setting the bookmark (i.e., navigating the form's Recordset navigates the form's edit buffer automatically, so the user sees the move immediately), but I prefer the indirection of the RecordsetClone.

If you want to make address directly, the worksheet must exist.

Turning off automatic recalculation want help you :)

But... you can get value indirectly...

.FormulaR1C1 = "=INDIRECT(ADDRESS(2,7,1,0,""" & strProjectName & """),FALSE)"

At the time formula is inserted it will return #REF error, because strProjectName sheet does not exist.

But after this worksheet appear Excel will calculate formula again and proper value will be shown.
Disadvantage: there will be no tracking, so if you move the cell or change worksheet name, the formula will not adjust to the changes as in the direct addressing.

The $.getJSON() method does an HTTP GET and not POST. You need to use $.post()

$.post(url, dataToBeSent, function(data, textStatus) {
  //data contains the JSON object
  //textStatus contains the status: success, error, etc
}, "json");

In that call, dataToBeSent could be anything you want, although if are sending the contents of a an html form, you can use the serialize method to create the data for the POST from your form.

var dataToBeSent = $("form").serialize();

1. Add a new install project to your solution.
2. Add targets from all projects you want to be installed.
3. Configure pre-requirements and choose "Check for .NET 3.5 and SQL Express" option. Choose the location from where missing components must be installed.
4. Configure your installer settings - company name, version, copyright, etc.
5. Build and go!

The answer may be outdated, since there is a name property on the UploadedFile class. See: Uploaded Files and Upload Handlers (Django docs). So, if you bind your form with a FileField correctly, the access should be as easy as:

if form.is_valid():
    form.cleaned_data['my_file'].name

IMHO Lookup tables is the way to go, with referential integrity. But only if you avoid "Evil Magic Numbers" by following an example such as this one: Generate enum from a database lookup table using T4

Have Fun!

Here is a very easy way of doing that

 $(function () {
    $(".glyphicon").unbind('click');
    $(".glyphicon").click(function (e) {
        $(this).toggleClass("glyphicon glyphicon-chevron-up glyphicon glyphicon-chevron-down");
});

Hope this helps :D

This answer does not work anymore, but I'm looking for a solution.

As of . 2015 / 02 / 24 . there is a website (youtubeinmp4) that allows you to download youtube videos in .mp4 format, you can exploit this (with some JavaScript) to get away with embedding youtube videos in <video> tags. Here is a demo of this in action.

##Pros

• Fairly easy to implement.
• Quite fast server response actually (it doesn't take that much to retrieve the videos).
• Abstraction (the accepted solution, even if it worked properly, would only be applicable if you knew beforehand which videos you were going to play, this works for any user inputted url).

##Cons

• It obviously depends on the youtubeinmp4.com servers and their way of providing a downloading link (which can be passed as a <video> source), so this answer may not be valid in the future.

• You can't choose the video quality.

###JavaScript (after load)

videos = document.querySelectorAll("video");
for (var i = 0, l = videos.length; i < l; i++) {
    var video = videos[i];
    var src = video.src || (function () {
        var sources = video.querySelectorAll("source");
        for (var j = 0, sl = sources.length; j < sl; j++) {
            var source = sources[j];
            var type = source.type;
            var isMp4 = type.indexOf("mp4") != -1;
            if (isMp4) return source.src;
        }
        return null;
    })();
    if (src) {
        var isYoutube = src && src.match(/(?:youtu|youtube)(?:\.com|\.be)\/([\w\W]+)/i);
        if (isYoutube) {
            var id = isYoutube[1].match(/watch\?v=|[\w\W]+/gi);
            id = (id.length > 1) ? id.splice(1) : id;
            id = id.toString();
            var mp4url = "http://www.youtubeinmp4.com/redirect.php?video=";
            video.src = mp4url + id;
        }
    }
}

###Usage (Full)

<video controls="true">
        <source src="www.youtube.com/watch?v=3bGNuRtlqAQ" type="video/mp4" />
    </video>

Standard video format.

###Usage (Mini)

<video src="youtu.be/MLeIBFYY6UY" controls="true"></video>

A little less common but quite smaller, using the shortened url youtu.be as the src attribute directly in the <video> tag.

Sounds like myversioncontrol.com have added a pre-commit hook, or have one that is now failing. If it's a free account, it might be you've exceeded some sort of monthly commit or bandwidth limit. Check their terms of service and/or contact them to see what's up.

UPDATE:
I've just checked their website, and it looks like the free account is only valid for 30 days, so you might've exceeded that. You may need to pony up the £3.50pcm or find somewhere else (Google Code is one suggestion, though there are others).

Simon Groenewolt makes a good point that you may have changed something in the control panel on their website that has turned on a pre-commit hook but where it's configured incorrectly.

myList.Any(myString.Contains);

I run cntlm localy, configured with NTLMv2 password hashes to authenticate with the corporate proxy, and use

export MAVEN_OPTS="-DproxyHost=127.0.0.1 -DproxyPort=3128"

to use that proxy from maven. Of course the proxy you use should support cntlm/NTLMv2.

You can try the Class Based View called RedirectView

from django.views.generic.base import RedirectView

urlpatterns = patterns('',
    url(r'^$', 'macmonster.views.home'),
    #url(r'^macmon_home$', 'macmonster.views.home'),
    url(r'^macmon_output/$', 'macmonster.views.output'),
    url(r'^macmon_about/$', 'macmonster.views.about'),
    url(r'^.*$', RedirectView.as_view(url='<url_to_home_view>', permanent=False), name='index')
)

Notice how as url in the <url_to_home_view> you need to actually specify the url.

permanent=False will return HTTP 302, while permanent=True will return HTTP 301.

Alternatively you can use django.shortcuts.redirect

Update for Django 2+ versions

With Django 2+, url() is deprecated and replaced by re_path(). Usage is exactly the same as url() with regular expressions. For replacements without the need of regular expression, use path().

from django.urls import re_path

re_path(r'^.*$', RedirectView.as_view(url='<url_to_home_view>', permanent=False), name='index')

Try WANem

WANem is a Wide Area Network Emulator, meant to provide a real experience of a Wide Area Network/Internet, during application development / testing over a LAN environment.

Python 3.6+ provides built-in convenience methods to find and decode the plain text body as in @Todor Minakov's answer. You can use the EMailMessage.get_body() and get_content() methods:

msg = email.message_from_string(s, policy=email.policy.default)
body = msg.get_body(('plain',))
if body:
    body = body.get_content()
print(body)

Note this will give None if there is no (obvious) plain text body part.

If you are reading from e.g. an mbox file, you can give the mailbox constructor an EmailMessage factory:

mbox = mailbox.mbox(mboxfile, factory=lambda f: email.message_from_binary_file(f, policy=email.policy.default), create=False)
for msg in mbox:
    ...

Note you must pass email.policy.default as the policy, since it's not the default...

For me it worked to add the phrase "explicit_defaults_for_timestamp = ON" without quotes into the config file my.ini.

Make sure you add this phrase right underneath the [mysqld] statement in the config file.

You will find my.ini under C:\ProgramData\MySQL\MySQL Server 5.7 if you had conducted the default installation of MySQL.

Like reorder() in Alex Brown's answer, we could also use forcats::fct_reorder(). It will basically sort the factors specified in the 1st arg, according to the values in the 2nd arg after applying a specified function (default = median, which is what we use here as just have one value per factor level).

It is a shame that in the OP's question, the order required is also alphabetical as that is the default sort order when you create factors, so will hide what this function is actually doing. To make it more clear, I'll replace "Goalkeeper" with "Zoalkeeper".

library(tidyverse)
library(forcats)

theTable <- data.frame(
                Name = c('James', 'Frank', 'Jean', 'Steve', 'John', 'Tim'),
                Position = c('Zoalkeeper', 'Zoalkeeper', 'Defense',
                             'Defense', 'Defense', 'Striker'))

theTable %>%
    count(Position) %>%
    mutate(Position = fct_reorder(Position, n, .desc = TRUE)) %>%
    ggplot(aes(x = Position, y = n)) + geom_bar(stat = 'identity')

To add to @DennisWilliamson comment above:

@VaibhavBajpai: Try this: response=$(curl --write-out \n%{http_code} --silent --output - servername) - the last line in the result will be the response code

You can then parse the response code from the response using something like the following, where X can signify a regex to mark the end of the response (using a json example here)

X='*\}'
code=$(echo ${response##$X})

See Substring Removal: http://tldp.org/LDP/abs/html/string-manipulation.html

Just define:

#define M_PI acos(-1.0)

It should give you exact PI number that math functions are working with. So if they change PI value they are working with in tangent or cosine or sine, then your program should be always up-to-dated ;)

From sun docs:

\s A whitespace character: [ \t\n\x0B\f\r]

The simplest way is to use it with regex.

No, Cookies can be cleaned only by setting the Expiry date for each of them.

if (Request.Cookies["UserSettings"] != null)
{
    HttpCookie myCookie = new HttpCookie("UserSettings");
    myCookie.Expires = DateTime.Now.AddDays(-1d);
    Response.Cookies.Add(myCookie);
}

At the moment of Session.Clear():

• All the key-value pairs from Session collection are removed. Session_End event is not happen.

If you use this method during logout, you should also use the Session.Abandon method to Session_End event:

• Cookie with Session ID (if your application uses cookies for session id store, which is by default) is deleted

This guide is oriented to developers who already have an application in the Play Store. If you are starting with a new app the process it's much easier and you can follow the guidelines of paragraph "New apps" from here

Prerequisites that 99% of developers already have :

1. Android Studio

2. JDK 8 and after installation you need to setup an environment variable in your user space to simplify terminal commands. In Windows x64 you need to add this : C:\Program Files\Java\{JDK_VERSION}\bin to the Path environment variable. (If you don't know how to do this you can read my guide to add a folder to the Windows 10 Path environment variable).

Step 0: Open Google Play developer console, then go to Release Management -> App Signing.

Accept the App Signing TOS.

Step 1: Download PEPK Tool clicking the button identical to the image below

Step 2: Open a terminal and type:

java -jar PATH_TO_PEPK --keystore=PATH_TO_KEYSTORE --alias=ALIAS_YOU_USE_TO_SIGN_APK --output=PATH_TO_OUTPUT_FILE --encryptionkey=GOOGLE_ENCRYPTION_KEY

Legend:

• PATH_TO_PEPK = Path to the pepk.jar you downloaded in Step 1, could be something like C:\Users\YourName\Downloads\pepk.jar for Windows users.
• PATH_TO_KEYSTORE = Path to keystore which you use to sign your release APK. Could be a file of type *.keystore or *.jks or without extension. Something like C:\Android\mykeystore or C:\Android\mykeystore.keystore etc...
• ALIAS_YOU_USE_TO_SIGN_APK = The name of the alias you use to sign the release APK.
• PATH_TO_OUTPUT_FILE = The path of the output file with .pem extension, something like C:\Android\private_key.pem
• GOOGLE_ENCRYPTION_KEY = This encryption key should be always the same. You can find it in the App Signing page, copy and paste it. Should be in this form: eb10fe8f7c7c9df715022017b00c6471f8ba8170b13049a11e6c09ffe3056a104a3bbe4ac5a955f4ba4fe93fc8cef27558a3eb9d2a529a2092761fb833b656cd48b9de6a

Example:

java -jar "C:\Users\YourName\Downloads\pepk.jar" --keystore="C:\Android\mykeystore" --alias=myalias --output="C:\Android\private_key.pem" --encryptionkey=eb10fe8f7c7c9df715022017b00c6471f8ba8170b13049a11e6c09ffe3056a104a3bbe4ac5a955f4ba4fe93fc8cef27558a3eb9d2a529a2092761fb833b656cd48b9de6a

Press Enter and you will need to provide in order:

1. The keystore password
2. The alias password

If everything has gone OK, you now will have a file in PATH_TO_OUTPUT_FILE folder called private_key.pem.

Step 3: Upload the private_key.pem file clicking the button identical to the image below

Step 4: Create a new keystore file using Android Studio.

YOU WILL NEED THIS KEYSTORE IN THE FUTURE TO SIGN THE NEXT RELEASES OF YOUR APP, DON'T FORGET THE PASSWORDS

Open one of your Android projects (choose one at random). Go to Build -> Generate Signed APK and press Create new.

Now you should fill the required fields.

Key store path represent the new keystore you will create, choose a folder and a name using the 3 dots icon on the right, i choosed C:\Android\upload_key.jks (.jks extension will be added automatically)

NOTE: I used upload as the new alias name but if you previously used the same keystore with different aliases to sign different apps, you should choose the same aliases name you had previously in the original keystore.

Press OK when finished, and now you will have a new upload_key.jks keystore. You can close Android Studio now.

Step 5: We need to extract the upload certificate from the newly created upload_key.jks keystore. Open a terminal and type:

keytool -export -rfc -keystore UPLOAD_KEYSTORE_PATH -alias UPLOAD_KEYSTORE_ALIAS -file PATH_TO_OUTPUT_FILE

Legend:

• UPLOAD_KEYSTORE_PATH = The path of the upload keystore you just created. In this case was C:\Android\upload_key.jks.
• UPLOAD_KEYSTORE_ALIAS = The new alias associated with the upload keystore. In this case was upload.
• PATH_TO_OUTPUT_FILE = The path to the output file with .pem extension. Something like C:\Android\upload_key_public_certificate.pem.

Example:

keytool -export -rfc -keystore "C:\Android\upload_key.jks" -alias upload -file "C:\Android\upload_key_public_certificate.pem"

Press Enter and you will need to provide the keystore password.

Now if everything has gone OK, you will have a file in the folder PATH_TO_OUTPUT_FILE called upload_key_public_certificate.pem.

Step 6: Upload the upload_key_public_certificate.pem file clicking the button identical to the image below

Step 7: Click ENROLL button at the end of the App Signing page.

Now every new release APK must be signed with the upload_key.jks keystore and aliases created in Step 4, prior to be uploaded in the Google Play Developer console.

• Google documentation on Google Play App Signing
• Form to request the reset of your upload keystore if you lose it

Q&A

Q: When i upload the APK signed with the new upload_key keystore, Google Play show an error like : You uploaded an unsigned APK. You need to create a signed APK.

A: Check to sign the APK with both signatures (V1 and V2) while building the release APK. Read here for more details.

UPDATED

The step 4,5,6 are to create upload key which is optional for existing apps

"Upload key (optional for existing apps): A new key you generate during your enrollment in the program. You will use the upload key to sign all future APKs prior to uploading them to the Play Console." https://support.google.com/googleplay/android-developer/answer/7384423

To answer the original question:

HTMLDocument doc = new HTMLDocument();
IHTMLDocument2 doc2 = (IHTMLDocument2)doc;
doc2.write(fileText);
// now use doc

Then to convert back to a string:

doc.documentElement.outerHTML;

The answer I guess, is yes. Check this link for instance.

Issuing an SSL Certificate to a Public IP Address

An SSL certificate is typically issued to a Fully Qualified Domain Name (FQDN) such as "https://www.domain.com". However, some organizations need an SSL certificate issued to a public IP address. This option allows you to specify a public IP address as the Common Name in your Certificate Signing Request (CSR). The issued certificate can then be used to secure connections directly with the public IP address (e.g., https://123.456.78.99.).

What's your goal?

If set icon image size to bigger one:

1. Make sure to have a bigger image size than your target size (so you can set max image size for your icon)

2. My target icon image size is 84dp & fab size is 112dp:

   <android.support.design.widget.FloatingActionButton
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:layout_gravity="center"
       android:src= <image here>
       app:fabCustomSize="112dp"
       app:fabSize="auto"
       app:maxImageSize="84dp" />

Division of two numbers using bitwise operators.

#include <stdio.h>

int remainder, divisor;

int division(int tempdividend, int tempdivisor) {
    int quotient = 1;

    if (tempdivisor == tempdividend) {
        remainder = 0;
        return 1;
    } else if (tempdividend < tempdivisor) {
        remainder = tempdividend;
        return 0;
    }   

    do{

        tempdivisor = tempdivisor << 1;
        quotient = quotient << 1;

     } while (tempdivisor <= tempdividend);


     /* Call division recursively */
    quotient = quotient + division(tempdividend - tempdivisor, divisor);

    return quotient;
} 


int main() {
    int dividend;

    printf ("\nEnter the Dividend: ");
    scanf("%d", &dividend);
    printf("\nEnter the Divisor: ");
    scanf("%d", &divisor);   

    printf("\n%d / %d: quotient = %d", dividend, divisor, division(dividend, divisor));
    printf("\n%d / %d: remainder = %d", dividend, divisor, remainder);
    getch();
}

Ok, call me paranoid but I suggest:

  final android.view.ViewParent parent = view.getParent ();

  if (parent instanceof android.view.ViewManager)
  {
     final android.view.ViewManager viewManager = (android.view.ViewManager) parent;

     viewManager.removeView (view);
  } // if

casting without instanceof just seems wrong. And (thanks IntelliJ IDEA for telling me) removeView is part of the ViewManager interface. And one should not cast to a concrete class when a perfectly suitable interface is available.

NOTE: This should be considered a discussion rather than an actual answer.

An approximate approach is to operate __main__ in the module you want to create variables. For example there's a b.py:

#!/usr/bin/env python
# coding: utf-8


def set_vars():
    import __main__
    print '__main__', __main__
    __main__.B = 1

try:
    print B
except NameError as e:
    print e

set_vars()

print 'B: %s' % B

Running it would output

$ python b.py
name 'B' is not defined
__main__ <module '__main__' from 'b.py'>
B: 1

But this approach only works in a single module script, because the __main__ it import will always represent the module of the entry script being executed by python, this means that if b.py is involved by other code, the B variable will be created in the scope of the entry script instead of in b.py itself. Assume there is a script a.py:

#!/usr/bin/env python
# coding: utf-8

try:
    import b
except NameError as e:
    print e

print 'in a.py: B', B

Running it would output

$ python a.py
name 'B' is not defined
__main__ <module '__main__' from 'a.py'>
name 'B' is not defined
in a.py: B 1

Note that the __main__ is changed to 'a.py'.

It is not possible with the standard query operators - it is Language Integrated Query, not Language Integrated Update. But you could hide your update in extension methods.

public static class UpdateExtension
{
    public static IEnumerable<Car> ChangeColorTo(
       this IEnumerable<Car> cars, Color color)
    {
       foreach (Car car in cars)
       {
          car.Color = color;
          yield return car;
       }
    }
}

Now you can use it as follows.

cars.Where(car => car.Color == Color.Blue).ChangeColorTo(Color.Red);

Keep in mind that SQL strings can not be larger than 4000 bytes, while Pl/SQL can have strings as large as 32767 bytes. see below for an example of inserting a large string via an anonymous block which I believe will do everything you need it to do.

note I changed the varchar2(32000) to CLOB

set serveroutput ON 
CREATE TABLE testclob 
  ( 
     id NUMBER, 
     c  CLOB, 
     d  VARCHAR2(4000) 
  ); 

DECLARE 
    reallybigtextstring CLOB := '123'; 
    i                   INT; 
BEGIN 
    WHILE Length(reallybigtextstring) <= 60000 LOOP 
        reallybigtextstring := reallybigtextstring 
                               || '000000000000000000000000000000000'; 
    END LOOP; 

    INSERT INTO testclob 
                (id, 
                 c, 
                 d) 
    VALUES     (0, 
                reallybigtextstring, 
                'done'); 

    dbms_output.Put_line('I have finished inputting your clob: ' 
                         || Length(reallybigtextstring)); 
END; 

/ 
SELECT * 
FROM   testclob; 


 "I have finished inputting your clob: 60030"

as suggested here solving the famous LazyInitializationException is one of the following methods:

(1) Use Hibernate.initialize

Hibernate.initialize(topics.getComments());

(2) Use JOIN FETCH

You can use the JOIN FETCH syntax in your JPQL to explicitly fetch the child collection out. This is somehow like EAGER fetching.

(3) Use OpenSessionInViewFilter

LazyInitializationException often occurs in the view layer. If you use Spring framework, you can use OpenSessionInViewFilter. However, I do not suggest you to do so. It may leads to a performance issue if not used correctly.
