You could extend the String object with your own function that does what you need (useful if there's ever missing functionality):

String.prototype.replaceArray = function(find, replace) {
  var replaceString = this;
  for (var i = 0; i < find.length; i++) {
    replaceString = replaceString.replace(find[i], replace[i]);
  }
  return replaceString;
};

For global replace you could use regex:

String.prototype.replaceArray = function(find, replace) {
  var replaceString = this;
  var regex; 
  for (var i = 0; i < find.length; i++) {
    regex = new RegExp(find[i], "g");
    replaceString = replaceString.replace(regex, replace[i]);
  }
  return replaceString;
};

To use the function it'd be similar to your PHP example:

var textarea = $(this).val();
var find = ["<", ">", "\n"];
var replace = ["&lt;", "&gt;", "<br/>"];
textarea = textarea.replaceArray(find, replace);

This should do the trick:

<table width="400" border="0" cellpadding="0" cellspacing="0">
  <tr>
    <td width="50" height="40" valign="top" rowspan="3">
      <img alt="" src="" width="40" height="40" style="margin: 0; border: 0; padding: 0; display: block;">
    </td>
    <td width="350" height="40" style="font-family: Helvetica, Arial, sans-serif; font-size: 14px; color: #000000;">
<a href="" style="color: #D31145; font-weight: bold; text-decoration: none;">LAST FIRST</a><br>

    </td>
  </tr>
  <tr>
    <td width="350" height="70" valign="bottom" style="font-family: Helvetica, Arial, sans-serif; font-size: 14px; color: #000000;">
<img alt="" src="" width="200" height="60" style="margin: 0; border: 0; padding: 0; display: block;">
    </td>
  </tr>
  <tr>
    <td width="350" height="20" valign="bottom" style="font-family: Helvetica, Arial, sans-serif; font-size: 10px; color: #000000;">
all your minor text here | all your minor text here | all your minor text here
    </td>
  </tr>
</table>

UPDATE: Adjusted code per the comments:

After viewing your jsFiddle, an important thing to note about tables is that table cell widths in each additional row all have to be the same width as the first, and all cells must add to the total width of your table.

Here is an example that will NOT WORK:

<table width="600" border="0" cellpadding="0" cellspacing="0">
  <tr>
    <td width="200" bgcolor="#252525">&nbsp;
    </td>
    <td width="400" bgcolor="#454545">&nbsp;
    </td>
  </tr>
  <tr>
    <td width="300" bgcolor="#252525">&nbsp;
    </td>
    <td width="300" bgcolor="#454545">&nbsp;
    </td>
  </tr>
</table>

Although the 2nd row does add up to 600, it (and any additional rows) must have the same 200-400 split as the first row, unless you are using colspans. If you use a colspan, you could have one row, but it needs to have the same width as the cells it is spanning, so this works:

<table width="600" border="0" cellpadding="0" cellspacing="0">
  <tr>
    <td width="200" bgcolor="#252525">&nbsp;
    </td>
    <td width="400" bgcolor="#454545">&nbsp;
    </td>
  </tr>
  <tr>
    <td width="600" colspan="2" bgcolor="#353535">&nbsp;
    </td>
  </tr>
</table>

Not a full tutorial, but I hope that helps steer you in the right direction in the future.

Here is the code you are after:

<table width="900" border="0" cellpadding="0" cellspacing="0">
  <tr>
    <td width="57" height="43" valign="top" rowspan="2">
      <img alt="Rashel Adragna" src="http://zoparealtygroup.com/wp-content/uploads/2013/10/sig_head.png" width="47" height="43" style="margin: 0; border: 0; padding: 0; display: block;">
    </td>
    <td width="843" height="43" style="font-family: Helvetica, Arial, sans-serif; font-size: 14px; color: #000000;">
<a href="" style="color: #D31145; font-weight: bold; text-decoration: none;">RASHEL ADRAGNA</a><br>
REALTOR | P 855.900.24KW
    </td>
  </tr>
  <tr>
    <td width="843" height="64" valign="bottom" style="font-family: Helvetica, Arial, sans-serif; font-size: 14px; color: #000000;">
<img alt="Zopa Realty Group logo" src="http://zoparealtygroup.com/wp-content/uploads/2013/10/sig_logo.png" width="177" height="54" style="margin: 0; border: 0; padding: 0; display: block;">
    </td>
  </tr>
  <tr>
    <td width="843" colspan="2" height="20" valign="bottom" align="center" style="font-family: Helvetica, Arial, sans-serif; font-size: 10px; color: #000000;">
all your minor text here | all your minor text here | all your minor text here
    </td>
  </tr>
</table>

You'll note that I've added an extra 10px to some of your table cells. This in combination with align/valigns act as padding between your cells. It is a clever way to aviod actually having to add padding, margins or empty padding cells.

import re
ipv=raw_input("Enter an ip address")
a=ipv.split('.')
s=str(bin(int(a[0]))+bin(int(a[1]))+bin(int(a[2]))+bin(int(a[3])))
s=s.replace("0b",".")
m=re.search('\.[0,1]{1,8}\.[0,1]{1,8}\.[0,1]{1,8}\.[0,1]{1,8}$',s)
if m is not None:
    print "Valid sequence of input"
else :
    print "Invalid input sequence"

Just to keep it simple I have used this approach. Simple as in to explain how really ipv4 address is evaluated. Checking whether its a binary number is although not required. Hope you like this.

Your problem here is that the dtype of 'Date' remained as str/object. You can use the parse_dates parameter when using read_csv

import pandas as pd
file = '/pathtocsv.csv'
df = pd.read_csv(file, sep = ',', parse_dates= [col],encoding='utf-8-sig', usecols= ['Date', 'ids'],)    
df['Month'] = df['Date'].dt.month

From the documentation for the parse_dates parameter

parse_dates : bool or list of int or names or list of lists or dict, default False

The behavior is as follows:

• boolean. If True -> try parsing the index.
• list of int or names. e.g. If [1, 2, 3] -> try parsing columns 1, 2, 3 each as a separate date column.
• list of lists. e.g. If [[1, 3]] -> combine columns 1 and 3 and parse as a single date column.
• dict, e.g. {‘foo’ : [1, 3]} -> parse columns 1, 3 as date and call result ‘foo’

If a column or index cannot be represented as an array of datetimes, say because of an unparseable value or a mixture of timezones, the column or index will be returned unaltered as an object data type. For non-standard datetime parsing, use pd.to_datetime after pd.read_csv. To parse an index or column with a mixture of timezones, specify date_parser to be a partially-applied pandas.to_datetime() with utc=True. See Parsing a CSV with mixed timezones for more.

Note: A fast-path exists for iso8601-formatted dates.

The relevant case for this question is the "list of int or names" one.

col is the columns index of 'Date' which parses as a separate date column.

if you know the application package you can cd directly to that folder..

eg cd data/data/com.yourapp

this will drop you into a directory that is read/writable so you can change files as needed. Since the folder is the same on the emulator, you can use that to get the folder path.

Either directly in form parameters or

string controlName = this.Request.Params.Get("__EVENTTARGET");

Edit: To check if a control caused a postback (manually):

// input Image with name="imageName"
if (this.Request["imageName"+".x"] != null) ...;//caused postBack

// Other input with name="name"
if (this.Request["name"] != null) ...;//caused postBack

You could also iterate through all the controls and check if one of them caused a postBack using the above code.

arrays:

• are a builtin language construct;
• come almost unmodified from C89;
• provide just a contiguous, indexable sequence of elements; no bells and whistles;
• are of fixed size; you can't resize an array in C++ (unless it's an array of POD and it's allocated with malloc);
• their size must be a compile-time constant unless they are allocated dynamically;
• they take their storage space depending from the scope where you declare them;
• if dynamically allocated, you must explicitly deallocate them;
• if they are dynamically allocated, you just get a pointer, and you can't determine their size; otherwise, you can use sizeof (hence the common idiom sizeof(arr)/sizeof(*arr), that however fails silently when used inadvertently on a pointer);
• automatically decay to a pointers in most situations; in particular, this happens when passing them to a function, which usually requires passing a separate parameter for their size;
• can't be returned from a function;
• can't be copied/assigned directly;
• dynamical arrays of objects require a default constructor, since all their elements must be constructed first;

std::vector:

• is a template class;
• is a C++ only construct;
• is implemented as a dynamic array;
• grows and shrinks dynamically;
• automatically manage their memory, which is freed on destruction;
• can be passed to/returned from functions (by value);
• can be copied/assigned (this performs a deep copy of all the stored elements);
• doesn't decay to pointers, but you can explicitly get a pointer to their data (&vec[0] is guaranteed to work as expected);
• always brings along with the internal dynamic array its size (how many elements are currently stored) and capacity (how many elements can be stored in the currently allocated block);
• the internal dynamic array is not allocated inside the object itself (which just contains a few "bookkeeping" fields), but is allocated dynamically by the allocator specified in the relevant template parameter; the default one gets the memory from the freestore (the so-called heap), independently from how where the actual object is allocated;
• for this reason, they may be less efficient than "regular" arrays for small, short-lived, local arrays;
• when reallocating, the objects are copied (moved, in C++11);
• does not require a default constructor for the objects being stored;
• is better integrated with the rest of the so-called STL (it provides the begin()/end() methods, the usual STL typedefs, ...)

Also consider the "modern alternative" to arrays - std::array; I already described in another answer the difference between std::vector and std::array, you may want to have a look at it.

The solution only solves part of the problem, it may let you style the container and contents but doesn't let you change the titlebar. I developed a workaround of sorts but adding an id to the dialog div, then using jQuery .prev to change the style of the div which is the previous sibling of the dialog's div. This works because when jQueryUI creates the dialog, your original div becomes a sibling of the new container, but the title div is a the immediately previous sibling to your original div but neither the container not the title div has an id to simplify selecting the div.

HTML

<button id="dialog1" class="btn btn-danger">Warning</button>
<div title="Nothing here, really" id="nonmodal1">
  Nothing here
</div>

You can use CSS to style the main section of the dialog but not the title

.custom-ui-widget-header-warning {
  background: #EBCCCC;
  font-size: 1em;
}

You need some JS to style the title

$(function() {
                   $("#nonmodal1").dialog({
                     minWidth: 400,
                     minHeight: 'auto',
                     autoOpen: false,
                     dialogClass: 'custom-ui-widget-header-warning',
                     position: {
                       my: 'center',
                       at: 'left'
                     }
                   });

                   $("#dialog1").click(function() {
                     if ($("#nonmodal1").dialog("isOpen") === true) {
                       $("#nonmodal1").dialog("close");
                     } else {
                       $("#nonmodal1").dialog("open").prev().css('background','#D9534F');

                     }
                   });
    });

The example only shows simple styling (background) but you can make it as complex as you wish.

You can see it in action here:

http://codepen.io/chris-hore/pen/OVMPay

I'm on Ubuntu 14.04, with Bash version 4.3.11. However, I still don't have the fun built in string manipulation ${y,,}

This is what I used in my script to force capitalization:

CAPITALIZED=`echo "${y}" | tr '[a-z]' '[A-Z]'`

KEY and INDEX are synonyms.

You should add an index when performance measurements and EXPLAIN shows you that the query is inefficient because of a missing index. Adding an index can improve the performance of queries (but it can slow down modifications to the table).

You should use UNIQUE when you want to contrain the values in that column (or columns) to be unique, so that attempts to insert duplicate values result in an error.

A PRIMARY KEY is both a unique constraint and it also implies that the column is NOT NULL. It is used to give an identity to each row. This can be useful for joining with another table via a foreign key constraint. While it is not required for a table to have a PRIMARY KEY it is usually a good idea.

You'll need to use System.Threading.Thread.Sleep(number of milliseconds).

WebBrowser1.Document.Window.DomWindow.execscript("checkPasswordConfirm();","JavaScript")

Threading.Thread.Sleep(500) ' 500 milliseconds = 0.5 seconds

Dim allelements As HtmlElementCollection = WebBrowser1.Document.All
For Each webpageelement As HtmlElement In allelements
    If webpageelement.InnerText = "Sign Up" Then
        webpageelement.InvokeMember("click")
    End If
Next

I had this issue with gulp. The problem was that gulp added a dependency to my source file and I think npm tried to open it:

{
  "name": "name",
  "version": "2.0.0",
  "description": "",
  "main": "gulpfile.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "appname": "file://gulp",
    "gulp-concat": "^2.6.1",
    "gulp-electron": "^0.1.3",
    "gulp-shell": "^0.5.2",
    "gulp-uglify": "^2.0.0",
    "gulp-util": "^3.0.7",
    "node-7z": "^0.4.0"
  }
}

Make sure that there are no strange references in you package.json file.

Angular version 6 "0.6.8" rxjs version 6 "^6.0.0"

this solution is for :

  "@angular-devkit/core": "0.6.8",
  "rxjs": "^6.0.0"

as we all know angular is being developed every day so there are lots of changes every day and this solution is for angular 6 and rxjs 6
first to work with http yo should import it from : after all you have to declare the HttpModule in app.module.ts

import { Http } from '@angular/http';

and you have to add HttpModule to Ngmodule -> imports

  imports: [
    HttpModule,
    BrowserModule,
    FormsModule,
    RouterModule.forRoot(appRoutes)
  ],

second to work with map you should first import pipe :

import { pipe } from 'rxjs';

third you need the map function import from :

import { map } from 'rxjs/operators';

you have to use map inside pipe like this exemple :

 constructor(public http:Http){  }

    getusersGET(){
        return this.http.get('http://jsonplaceholder.typicode.com/users').pipe(
         map(res => res.json()  )  );
    }

that works perfectly good luck !

To be able to automatically throw an error when x become less than zero throughout the function. You can use class descriptors. Here is an example:

class LessThanZeroException(Exception):
    pass

class variable(object):
    def __init__(self, value=0):
        self.__x = value

    def __set__(self, obj, value):
        if value < 0:
            raise LessThanZeroException('x is less than zero')

        self.__x  = value

    def __get__(self, obj, objType):
        return self.__x

class MyClass(object):
    x = variable()

>>> m = MyClass()
>>> m.x = 10
>>> m.x -= 20
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "my.py", line 7, in __set__
    raise LessThanZeroException('x is less than zero')
LessThanZeroException: x is less than zero

You need some tools like pdf2text to first convert your pdf to a text file and then search inside the text. (You will probably miss some information or symbols).

If you are using a programming language there are probably pdf libraries written for this purpose. e.g. http://search.cpan.org/dist/CAM-PDF/ for Perl

Mssql stored procedure vs function:

The data would probably have been posted originally from a web form looking a bit like this (but probably much more complicated):

<form action="http://example.com" method="post">

  User login    <input name="user[login]"    /><br />
  User password <input name="user[password]" /><br />

  <input type="submit" />
</form>

If the method were "get" instead of "post", clicking the submit button would take you to a URL looking a bit like this:

http://example.com/?user%5Blogin%5D=username&user%5Bpassword%5D=123456

or:

http://example.com/?user[login]=username&user[password]=123456

The web server on the other end will likely take the user[login] and user[password] parameters, and make them into a user object with login and password fields containing those values.

Yes, but you can select only one column in your subselect

SELECT (SELECT id FROM bla) AS my_select FROM bla2

I had the same problems:java.lang.NoClassDefFoundError: Could not initialize class com.xxx.HttpUtils

static {
    //code for loading properties from file
}

it is the environment problem.That means the properties in application.yml is incorrect or empty!

For those who are still frustrated, if you are using the experimental ART runtime, try switching back to dalvik (in developer options on device)

You can simply add data attribute in html input tag:

In rails html :

<%= form.text_field :appointment_date, 'data-provide': 'datepicker', 'data-date-start-date': "+0d" %>

HTML :

<input data-provide="datepicker" data-date-start-date="+0d" type="text" name="appointment_date" id="appointment_date">

Another option is to use DecimalFormat to format your numeric String. Here is one other way to do the job without having to use String.format if you are stuck in the pre 1.5 world:

static String intToString(int num, int digits) {
    assert digits > 0 : "Invalid number of digits";

    // create variable length array of zeros
    char[] zeros = new char[digits];
    Arrays.fill(zeros, '0');
    // format number as String
    DecimalFormat df = new DecimalFormat(String.valueOf(zeros));

    return df.format(num);
}

I think much has already been said, about RSS vs VSZ. From an administrator/programmer/user perspective, when I design/code applications I am more concerned about the RSZ, (Resident memory), as and when you keep pulling more and more variables (heaped) you will see this value shooting up. Try a simple program to build malloc based space allocation in loop, and make sure you fill data in that malloc'd space. RSS keeps moving up. As far as VSZ is concerned, it's more of virtual memory mapping that linux does, and one of its core features derived out of conventional operating system concepts. The VSZ management is done by Virtual memory management of the kernel, for more info on VSZ, see Robert Love's description on mm_struct and vm_struct, which are part of basic task_struct data structure in kernel.

I found a good example showing the differences between all hibernate save methods:

http://www.journaldev.com/3481/hibernate-session-merge-vs-update-save-saveorupdate-persist-example

In brief, according to the above link:

save()

• We can invoke this method outside a transaction. If we use this without transaction and we have cascading between entities, then only the primary entity gets saved unless we flush the session.
• So, if there are other objects mapped from the primary object, they gets saved at the time of committing transaction or when we flush the session.

persist()

• Its similar to using save() in transaction, so it’s safe and takes care of any cascaded objects.

saveOrUpdate()

• Can be used with or without the transaction, and just like save(), if its used without the transaction, mapped entities wont be saved un;ess we flush the session.

• Results into insert or update queries based on the provided data. If the data is present in the database, update query is executed.

update()

• Hibernate update should be used where we know that we are only updating the entity information. This operation adds the entity object to persistent context and further changes are tracked and saved when transaction is committed.
• Hence even after calling update, if we set any values in the entity,they will be updated when transaction commits.

merge()

• Hibernate merge can be used to update existing values, however this method create a copy from the passed entity object and return it. The returned object is part of persistent context and tracked for any changes, passed object is not tracked. This is the major difference with merge() from all other methods.

Also for practical examples of all these, please refer to the link I mentioned above, it shows examples for all these different methods.

Push only work for array .

Make your arrayText object to Array Object.

Try Like this

JS

this.arrayText = [{
  text1: 'Hello',
  text2: 'world',
}];

this.addText = function(text) {
  this.arrayText.push(text);
}
this.form = {
  text1: '',
  text2: ''
};

HTML

<div ng-controller="TestController as testCtrl">
  <form ng-submit="addText(form)">
    <input type="text" ng-model="form.text1" value="Lets go">
    <input type="text" ng-model="form.text2" value="Lets go again">
    <input type="submit" value="add">
  </form>
</div>

Assuming the application you are attempting to run in the background is CLI based, you can try calling the scheduled jobs using Hidden Start

Also see: http://www.howtogeek.com/howto/windows/hide-flashing-command-line-and-batch-file-windows-on-startup/

Entire difference is, you don't get $this supplied inside the static function. If you try to use $this, you'll get a Fatal error: Using $this when not in object context.

Well, okay, one other difference: an E_STRICT warning is generated by your first example.

Here is a little extension I just put together.

public static class PositionsExtension
{
    public static Int32 Position<TSource>(this IEnumerable<TSource> source,
                                          Func<TSource, bool> predicate)
    {
        return Positions<TSource>(source, predicate).FirstOrDefault();
    }
    public static IEnumerable<Int32> Positions<TSource>(this IEnumerable<TSource> source, 
                                                        Func<TSource, bool> predicate)
    {
        if (typeof(TSource) is IDictionary)
        {
            throw new Exception("Dictionaries aren't supported");
        }

        if (source == null)
        {
            throw new ArgumentOutOfRangeException("source is null");
        }
        if (predicate == null)
        {
            throw new ArgumentOutOfRangeException("predicate is null");
        }
        var found = source.Where(predicate).First();
        var query = source.Select((item, index) => new
            {
                Found = ReferenceEquals(item, found),
                Index = index

            }).Where( it => it.Found).Select( it => it.Index);
        return query;
    }
}

Then you can call it like this.

IEnumerable<Int32> indicesWhereConditionIsMet = 
      ListItems.Positions(item => item == this);

Int32 firstWelcomeMessage ListItems.Position(msg =>               
      msg.WelcomeMessage.Contains("Hello"));

Another way of getting the results

SELECT * from table WHERE SUBSTRING(tester, 1, 8)  <> 'username' or tester is null

What is happening is that next(a) returns the next value of a, which is printed to the console because it is not affected.

What you can do is affect a variable with this value:

>>> a = iter(list(range(10)))
>>> for i in a:
...    print(i)
...    b=next(a)
...
0
2
4
6
8

You would use the javascript date object:

MDN documentation for the Date object

var d = new Date();

Using bootstrap with font awesome.

<a class="btn btn-large btn-primary logout" href="#">
        <i class="fa fa-sign-out" aria-hidden="true">Logout</i>
</a>

I wouldn't access state in the Action Creator. I would use mapStateToProps() and import the entire state object and import a combinedReducer file (or import * from './reducers';) in the component the Action Creator is eventually going to. Then use destructuring in the component to use whatever you need from the state prop. If the Action Creator is passing the state onto a Reducer for the given TYPE, you don't need to mention state because the reducer has access to everything that is currently set in state. Your example is not updating anything. I would only use the Action Creator to pass along state from its parameters.

In the reducer do something like:

const state = this.state;
const apple = this.state.apples;

If you need to perform an action on state for the TYPE you are referencing, please do it in the reducer.

Please correct me if I'm wrong!!!

Quick and in some cases error-prone solution:

Find Regexp: (?sm)(.*?)([^\n]*\b(class|interface|enum)\b.*)

This will add the header to the first encountered class/interface/enum in the file. Class should have no existing header yet.

A little off topic, but if you want to migrate the data to a new table, and the possible duplicates are in the original table, and the column possibly duplicated is not an id, a GROUP BY will do:

INSERT INTO TABLE_2
(name)
  SELECT t1.name
  FROM TABLE_1 t1
  GROUP BY t1.name

You need to update your virtualbox sw. On new version, there is VBoxDarwinAdditions.pkg included in a additions iso image, in older versions is missing.

You can also do like this :

  $("#table-filters li").parent().find('li').removeClass("active");

Basically, you have two major choices:

• You can generate the identifier yourself, in which case you can use an assigned identifier.
• You can use the @GeneratedValue annotation and Hibernate will assign the identifier for you.

For the generated identifiers you have two options:

• UUID identifiers.
• Numerical identifiers.

For numerical identifiers you have three options:

• IDENTITY
• SEQUENCE
• TABLE

IDENTITY is only a good choice when you cannot use SEQUENCE (e.g. MySQL) because it disables JDBC batch updates.

SEQUENCE is the preferred option, especially when used with an identifier optimizer like pooled or pooled-lo.

TABLE is to be avoided since it uses a separate transaction to fetch the identifier and row-level locks which scales poorly.

use:

std::vector <Acard> playerHand;

everywhere qualify it by std::

or do:

using std::vector;

in your cpp file.

You have to do this because vector is defined in the std namespace and you do not tell your program to find it in std namespace, you need to tell that.

Update:

This linked answer describes a cleaner, simpler way of doing the same thing with C# syntax.

Original post

This is Microsoft's recommended way to handle WCF client calls:

For more detail see: Expected Exceptions

try
{
    ...
    double result = client.Add(value1, value2);
    ...
    client.Close();
}
catch (TimeoutException exception)
{
    Console.WriteLine("Got {0}", exception.GetType());
    client.Abort();
}
catch (CommunicationException exception)
{
    Console.WriteLine("Got {0}", exception.GetType());
    client.Abort();
}

Additional information

So many people seem to be asking this question on WCF that Microsoft even created a dedicated sample to demonstrate how to handle exceptions:

c:\WF_WCF_Samples\WCF\Basic\Client\ExpectedExceptions\CS\client

Download the sample: C# or VB

Considering that there are so many issues involving the using statement, (heated?) Internal discussions and threads on this issue, I'm not going to waste my time trying to become a code cowboy and find a cleaner way. I'll just suck it up, and implement WCF clients this verbose (yet trusted) way for my server applications.

Your hack of decrementing the count at the end is exactly that -- a hack.

Far better to write your loop correctly in the first place, so it doesn't count the last line twice.

int main() { 
    int number_of_lines = 0;
    std::string line;
    std::ifstream myfile("textexample.txt");

    while (std::getline(myfile, line))
        ++number_of_lines;
    std::cout << "Number of lines in text file: " << number_of_lines;
    return 0;
}

Personally, I think in this case, C-style code is perfectly acceptable:

int main() {
    unsigned int number_of_lines = 0;
    FILE *infile = fopen("textexample.txt", "r");
    int ch;

    while (EOF != (ch=getc(infile)))
        if ('\n' == ch)
            ++number_of_lines;
    printf("%u\n", number_of_lines);
    return 0;
}

Edit: Of course, C++ will also let you do something a bit similar:

int main() {
    std::ifstream myfile("textexample.txt");

    // new lines will be skipped unless we stop it from happening:    
    myfile.unsetf(std::ios_base::skipws);

    // count the newlines with an algorithm specialized for counting:
    unsigned line_count = std::count(
        std::istream_iterator<char>(myfile),
        std::istream_iterator<char>(), 
        '\n');

    std::cout << "Lines: " << line_count << "\n";
    return 0;
}

There's an O(N) solution for very specific cases where:

• the sets are both sorted
• both sorted in the same order

The following code assumes that both sets are based on the records comparable. A similar method could be based on on a Comparator.

    public class SortedSetComparitor <Foo extends Comparable<Foo>> 
            implements Comparator<SortedSet<Foo>> {

        @Override
        public int compare( SortedSet<Foo> arg0, SortedSet<Foo> arg1 ) {
            Iterator<Foo> otherRecords = arg1.iterator();
            for (Foo thisRecord : arg0) {
                // Shorter sets sort first.
                if (!otherRecords.hasNext()) return 1;
                int comparison = thisRecord.compareTo(otherRecords.next());
                if (comparison != 0) return comparison;
            }
            // Shorter sets sort first
            if (otherRecords.hasNext()) return -1;
            else return 0;
        }
    }

If you don't care about a minimum width for the div and really just don't want the div to expand across the whole container, you can float it left -- floated divs by default expand to support their contents, like so:

<form>
    <div style="float: left; background-color: blue">
        <input type="button" name="blah" value="lots and lots of characters"/>
        <input type="button" name="blah2" value="some characters"/>
    </div>
</form>

<body>

<form action="#" method="post" enctype="multipart/form-data">

    <input name="my_files[]" type="file" multiple="multiple" />
    <input type="submit" value="Upload Image" name="submit">
</form>


<?php

 if (isset($_FILES['my_files']))
  {
    $myFile = $_FILES['my_files'];
    $fileCount = count($myFile["name"]);


        for ($i = 0; $i <$fileCount; $i++)
         {
           $error = $myFile["error"][$i]; 

            if ($error == '4')  // error 4 is for "no file selected"
             {
               echo "no file selected";
             }
            else
             {

               $name =  $myFile["name"][$i];
               echo $name; 
               echo "<br>"; 
               $temporary_file = $myFile["tmp_name"][$i];
               echo $temporary_file;

               $type = $myFile["type"][$i];
               echo $type;
               echo "<br>";
               $size = $myFile["size"][$i];
               echo $size;
               echo "<br>";



               $target_path = "uploads/$name";   //first make a folder named "uploads" where you will upload files


                 if(move_uploaded_file($temporary_file,$target_path))

                   echo "<br>";
                   echo "<br>";
                  }
                   else
                  {
                   echo "no upload ";
                  }

But be alert. User can upload any type of file and also can hack your server or system by uploading a malicious or php file. In this script there should be some validations. Thank you.

The approved answer from @jbochi does not work for me. The str() function call raises an exception because it cannot encode the non-ascii characters in the BeautifulSoup element. Here is a more succinct way to filter the example web page to visible text.

html = open('21storm.html').read()
soup = BeautifulSoup(html)
[s.extract() for s in soup(['style', 'script', '[document]', 'head', 'title'])]
visible_text = soup.getText()

That was a stroll down memory lane...

I replaced awk by perl a long time ago.

Apparently the AWK regular expression engine does not capture its groups.

you might consider using something like :

perl -n -e'/test(\d+)/ && print $1'

the -n flag causes perl to loop over every line like awk does.

To run Android envirorment on low configuration machine.

1. Close the uncessesory web tabs in browser
2. For Antivirus users, exclude the build folder which is auto generated
3. Android studio have 1.2 Gb default heap can decrease to 512 MB

Help > Edit custom VM options

studio.vmoptions
 -Xmx512m

Layouts performace will be speed up

4. For Gradle one of the core component in Android studio Mkae sure like right now 3.0beta is latest one

Below tips can affect the code quality so please use with cautions:

1. Studio contain Power safe Mode when turned on it will close background operations that lint , code complelitions and so on.

2. You can run manually lint check when needed ./gradlew lint

3. Most of are using Android emulators on average it consume 2 GB RAM so if possible use actual Android device these will reduce your resource load on your computer. Alternatively you can reduce the RAM of the emulator and it will automatically reduce the virtual memory consumption on your computer. you can find this in virtual device configuration and advance setting.

4. Gradle offline mode is a feature for bandwidth limited users to disable the downloading of build dependencies. It will reduce the background operation that will help to increase the performance of Android studio.

5. Android studio offers an optimization to compile multiple modules in parallel. On low RAM machines this feature will likely have a negative impact on the performance. You can disable it in the compiler settings dialog.

Just use

plt.show()

This command tells the system to draw the plot in Pycharm.

Example:

plt.imshow(img.reshape((28, 28)))
plt.show()

You can follow the logic below to prevent auto rotate screen while your AsyncTask is running:

1. Store your current screen orientation inside your activity using getRequestedOrientation().
2. Disable auto screen orientation using setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_NOSENSOR).
3. Run/execute your AsyncTask.
4. At the end of your AsyncTask restore your previous orientation status using setRequestedOrientation(oldOrientation).

Please note that there are several ways to access Activity (which runs on UI thread) properties inside an AsyncTask. You can implement your AsyncTask as an inner class or you can use message Handler that poke your Activiy class.

You can do it by using simple one line JavaScript code and also be careful that if JavaScript is turned off it will not work. The below code will do it's job if JavaScript is turned off.

I would add another column on the data sheet with equation =month(A2), then run the countif on that column... If you still wanted to use text month('APRIL'), you would need a lookup table to reference the name to the month number. Otherwise, just use 4 instead of April on your metric sheet.

Beware float: left…

…there are many ways to align elements side-by-side.

Below are the most common ways to achieve two elements side-by-side…

Demo: View/edit all the below examples on Codepen

Basic styles for all examples below…

Some basic css styles for parent and child elements in these examples:

.parent {
  background: mediumpurple;
  padding: 1rem;
}
.child {
  border: 1px solid indigo;
  padding: 1rem;
}

Using the float solution my have unintended affect on other elements. (Hint: You may need to use a clearfix.)

html

<div class='parent'>
  <div class='child float-left-child'>A</div>
  <div class='child float-left-child'>B</div>
</div>

css

.float-left-child {
  float: left;
}

html

<div class='parent'>
  <div class='child inline-block-child'>A</div>
  <div class='child inline-block-child'>B</div>
</div>

css

.inline-block-child {
  display: inline-block;
}

Note: the space between these two child elements can be removed, by removing the space between the div tags:

html

<div class='parent'>
  <div class='child inline-block-child'>A</div><div class='child inline-block-child'>B</div>
</div>

css

.inline-block-child {
  display: inline-block;
}

html

<div class='parent flex-parent'>
  <div class='child flex-child'>A</div>
  <div class='child flex-child'>B</div>
</div>

css

.flex-parent {
  display: flex;
}
.flex-child {
  flex: 1;
}

html

<div class='parent inline-flex-parent'>
  <div class='child'>A</div>
  <div class='child'>B</div>
</div>

css

.inline-flex-parent {
  display: inline-flex;
}

html

<div class='parent grid-parent'>
  <div class='child'>A</div>
  <div class='child'>B</div>
</div>

css

.grid-parent {
  display: grid;
  grid-template-columns: 1fr 1fr
}

I had a similar problem when I deployed my Flask app in the IIS. Apparently, IIS does not accept route that include an underline ("_"). When I removed the underline, problem was resolved.

To convert any JSON to array, use the below code:

const usersJson: any[] = Array.of(res.json());

/**
 * Clones the provided array
 * 
 * @param src
 * @return a new clone of the provided array
 */
public static int[][] cloneArray(int[][] src) {
    int length = src.length;
    int[][] target = new int[length][src[0].length];
    for (int i = 0; i < length; i++) {
        System.arraycopy(src[i], 0, target[i], 0, src[i].length);
    }
    return target;
}

Is it possible to modify this code to support n-dimensional arrays of Objects?

You would need to support arbitrary lengths of arrays and check if the src and destination have the same dimensions, and you would also need to copy each element of each array recursively, in case the Object was also an array.

It's been a while since I posted this, but I found a nice example of one way to create an n-dimensional array class. The class takes zero or more integers in the constructor, specifying the respective size of each dimension. The class uses an underlying flat array Object[] and calculates the index of each element using the dimensions and an array of multipliers. (This is how arrays are done in the C programming language.)

Copying an instance of NDimensionalArray would be as easy as copying any other 2D array, though you need to assert that each NDimensionalArray object has equal dimensions. This is probably the easiest way to do it, since there is no recursion, and this makes representation and access much simpler.

Apples and oranges. Firebase is a Backend-as-a-Service containing identity management, realtime data views and a document database. It runs in the cloud.

MongoDB on the other hand is a full fledged database with a rich query language. In principle it runs on your own machine, but there are cloud providers.

If you are looking for the database component only MongoDB is much more mature and feature-rich.

My pqsql is installed here: C:\Program Files\PostgreSQL\10\bin\psql.exe

You can add the location of psql.exe to your Path environment variable as shown in this screenshot:

The code below gives the HEX and RGB value of the range whether formatted using conditional formatting or otherwise. If the range is not formatted using Conditional Formatting and you intend to use iColor function in the Excel as UDF. It won't work. Read the below excerpt from MSDN.

Note that the DisplayFormat property does not work in user defined functions. For example, in a worksheet function that returns the interior color of a cell, if you use a line similar to:

Range.DisplayFormat.Interior.ColorIndex

then the worksheet function executes to return a #VALUE! error. If you are not finding color of the conditionally formatted range, then I encourage you to rather use

Range.Interior.ColorIndex

as then the function can also be used as UDF in Excel. Such as iColor(B1,"HEX")

Public Function iColor(rng As Range, Optional formatType As String) As Variant
'formatType: Hex for #RRGGBB, RGB for (R, G, B) and IDX for VBA Color Index
    Dim colorVal As Variant
    colorVal = rng.DisplayFormat.Interior.Color
    Select Case UCase(formatType)
        Case "HEX"
            iColor = "#" & Format(Hex(colorVal Mod 256),"00") & _
                           Format(Hex((colorVal \ 256) Mod 256),"00") & _
                           Format(Hex((colorVal \ 65536)),"00")
        Case "RGB"
            iColor = Format((colorVal Mod 256),"00") & ", " & _
                     Format(((colorVal \ 256) Mod 256),"00") & ", " & _
                     Format((colorVal \ 65536),"00")
        Case "IDX"
            iColor = rng.Interior.ColorIndex
        Case Else
            iColor = colorVal
    End Select
End Function

'Example use of the iColor function
Sub Get_Color_Format()
    Dim rng As Range

    For Each rng In Selection.Cells
        rng.Offset(0, 1).Value = iColor(rng, "HEX")
        rng.Offset(0, 2).Value = iColor(rng, "RGB")
    Next
End Sub

Use \df to list all the stored procedure in Postgres.

Might not be relevant for everyone but this little detail was causing mine not to work:

Change div from this:

<div class="map">

To this:

<div id="map">

Chain both class selectors (without a space in between):

.foo.bar {
    /* Styles for element(s) with foo AND bar classes */
}

If you still have to deal with ancient browsers like IE6, be aware that it doesn't read chained class selectors correctly: it'll only read the last class selector (.bar in this case) instead, regardless of what other classes you list.

To illustrate how other browsers and IE6 interpret this, consider this CSS:

* {
    color: black;
}

.foo.bar {
    color: red;
}

Output on supported browsers is:

<div class="foo">Hello Foo</div>       <!-- Not selected, black text [1] -->
<div class="foo bar">Hello World</div> <!-- Selected, red text [2] -->
<div class="bar">Hello Bar</div>       <!-- Not selected, black text [3] -->

Output on IE6 is:

<div class="foo">Hello Foo</div>       <!-- Not selected, black text [1] -->
<div class="foo bar">Hello World</div> <!-- Selected, red text [2] -->
<div class="bar">Hello Bar</div>       <!-- Selected, red text [2] -->

Footnotes:

• Supported browsers:
  1. Not selected as this element only has class foo.
  2. Selected as this element has both classes foo and bar.
  3. Not selected as this element only has class bar.
     
     
• IE6:
  1. Not selected as this element doesn't have class bar.
  2. Selected as this element has class bar, regardless of any other classes listed.

Try something like this...

<div id="wrapper" style="width:100%; text-align:center">
<img id="yourimage"/>
</div>

Here's how I did it:

@media (pointer:none), (pointer:coarse) {

Tie::File is what you need:

# This file documents Tie::File version 0.98
use Tie::File;

tie @array, 'Tie::File', 'filename' or die ...;

$array[13] = 'blah';     # line 13 of the file is now 'blah'
print $array[42];        # display line 42 of the file

$n_recs = @array;        # how many records are in the file?
$#array -= 2;            # chop two records off the end


for (@array) {
  s/PERL/Perl/g;         # Replace PERL with Perl everywhere in the file
}

# These are just like regular push, pop, unshift, shift, and splice
# Except that they modify the file in the way you would expect

push @array, new recs...;
my $r1 = pop @array;
unshift @array, new recs...;
my $r2 = shift @array;
@old_recs = splice @array, 3, 7, new recs...;

untie @array;            # all finished

You can do it like this and you mod function will work perfect let me know if you want a code pen

  <div ng-repeat="icon in icons">                   
                <div class="row" ng-if="$index % 3 == 0 ">
                    <i class="col col-33 {{icons[$index + n].icon}} custom-icon"></i>
                    <i class="col col-33 {{icons[$index + n + 1].icon}} custom-icon"></i>
                    <i class="col col-33 {{icons[$index + n + 2].icon}} custom-icon"></i>
                </div>
         </div>

The official ports (TCP:5222 and TCP:5269) are listed in RFC 6120. Contrary to the claims of a previous answer, XEP-0174 does not specify a port. Thus TCP:5298 might be customary for Link-Local XMPP, but is not official.

You can use other ports than the reserved ones, though: You can make your DNS SRV record point to any machine and port you like.

File transfers (XEP-0234) are these days handled using Jingle (XEP-0166). The same goes for RTP sessions (XEP-0167). They do not specify ports, though, since Jingle negotiates the creation of the data stream between the XMPP clients, but the actual data is then transferred by other means (e.g. RTP) through that stream (i.e. not usually through the XMPP server, even though in-band transfers are possible). Beware that Jingle is comprised of several XEPs, so make sure to have a look at the whole list of XMPP extensions.

Easy! The default should be the first option. Done! That would lead you to unobtrusive JavaScript, because JavaScript isn't needed :)

Dominc has the right idea, but put the calculation on the other side of the expression.

SELECT * FROM my_table WHERE endTime < DATE_SUB(CONVERT_TZ(NOW(), @@global.time_zone, 'GMT'), INTERVAL 30 MINUTE)

This has the advantage that you're doing the 30 minute calculation once instead of on every row. That also means MySQL can use the index on that column. Both of thse give you a speedup.

All of the answers above break expected browser behavior. What most people want is something that will scroll to the top if it's a "new" page, but return to the previous position if you're getting there through the Back (or Forward) button.

If you assume HTML5 mode, this turns out to be easy (although I'm sure some bright folks out there can figure out how to make this more elegant!):

// Called when browser back/forward used
window.onpopstate = function() { 
    $timeout.cancel(doc_scrolling); 
};

// Called after ui-router changes state (but sadly before onpopstate)
$scope.$on('$stateChangeSuccess', function() {
    doc_scrolling = $timeout( scroll_top, 50 );

// Moves entire browser window to top
scroll_top = function() {
    document.body.scrollTop = document.documentElement.scrollTop = 0;
}

The way it works is that the router assumes it is going to scroll to the top, but delays a bit to give the browser a chance to finish up. If the browser then notifies us that the change was due to a Back/Forward navigation, it cancels the timeout, and the scroll never occurs.

I used raw document commands to scroll because I want to move to the entire top of the window. If you just want your ui-view to scroll, then set autoscroll="my_var" where you control my_var using the techniques above. But I think most people will want to scroll the entire page if you are going to the page as "new".

The above uses ui-router, though you could use ng-route instead by swapping $routeChangeSuccess for$stateChangeSuccess.

Yes, you need $(this) for jQuery functions, but when you want to access basic javascript methods of the element that don't use jQuery, you can just use this.

Your app is being detected as some harmful program. Turn off "Verify apps over USB" option. It's in the same view as "USB debugging".

actually , this has turned out to be couple of javascript changes in the code. calling of javascript method with ; at the end. placing script tags in body instead of head. and interestingly even change the text displayed (please "click") to something that is not an event. so Please rate etc.

turned debugger on safari, it didnot give much information or even errors at times.

I just came across this page while looking for a set based solution to median. After looking at some of the solutions here, I came up with the following. Hope is helps/works.

DECLARE @test TABLE(
    i int identity(1,1),
    id int,
    score float
)

INSERT INTO @test (id,score) VALUES (1,10)
INSERT INTO @test (id,score) VALUES (1,11)
INSERT INTO @test (id,score) VALUES (1,15)
INSERT INTO @test (id,score) VALUES (1,19)
INSERT INTO @test (id,score) VALUES (1,20)

INSERT INTO @test (id,score) VALUES (2,20)
INSERT INTO @test (id,score) VALUES (2,21)
INSERT INTO @test (id,score) VALUES (2,25)
INSERT INTO @test (id,score) VALUES (2,29)

INSERT INTO @test (id,score) VALUES (3,21)
INSERT INTO @test (id,score) VALUES (3,25)
INSERT INTO @test (id,score) VALUES (3,29)

DECLARE @counts TABLE(

@ is a shortcut option for v-on. Use @ only when you want to execute some Vue methods. As you are not executing Vue methods, instead you are calling javascript function, you need to use onchange attribute to call javascript function

<select name="LeaveType" onchange="onChange(this.value)" class="form-control">
 <option value="1">Annual Leave/ Off-Day</option>
 <option value="2">On Demand Leave</option>
</select>

function onChange(value) {
  console.log(value);
}

If you want to call Vue methods, do it like this-

<select name="LeaveType" @change="onChange($event)" class="form-control">
 <option value="1">Annual Leave/ Off-Day</option>
 <option value="2">On Demand Leave</option>
</select>

new Vue({
  ...
  ...
  methods:{
    onChange:function(event){
       console.log(event.target.value);
    }
  }
})

You can use v-model data attribute on the select element to bind the value.

<select v-model="selectedValue" name="LeaveType" onchange="onChange(this.value)" class="form-control">
 <option value="1">Annual Leave/ Off-Day</option>
 <option value="2">On Demand Leave</option>
</select>

new Vue({
    data:{
        selectedValue : 1, // First option will be selected by default
    },
    ...
    ...
    methods:{
        onChange:function(event){
            console.log(this.selectedValue);
        }
    }
})

Hope this Helps :-)

You can use partial value of an attribute to detect a DOM element using (^) sign. For example you have divs like this:

<div id="abc_1"></div>
<div id="abc_2"></div>
<div id="xyz_3"></div>
<div id="xyz_4"></div>...

You can use the code:

var abc = $('div[id^=abc]')

This will return a DOM array of divs which have id starting with abc:

<div id="abc_1"></div>
<div id="abc_2"></div>

Here is the demo: http://jsfiddle.net/mCuWS/

If you are using the LESS or SASS Version of the Bootstrap. The most efficient way is to change the variable name, in the LESS or SASS file.

$navbar-default-color:              #FFFFFF !default;
$navbar-default-bg:                 #36669d !default;
$navbar-default-border:             $navbar-default-bg !default;

This by far the most easiest and the most efficient way to change the Bootstraps Navbar. You need not write overrides, and the code remains clean.

A better solution is not to make your page dependable on zoom settings. If you set limits like the one you are proposing, you are limiting accessibility. If someone cannot read your text well, they just won't be able to change that. I would use proper CSS to make it look nice in any zoom.

If your really insist, take a look at this question on how to detect zoom level using JavaScript (nightmare!): How to detect page zoom level in all modern browsers?

Put into a script I like something like that:

FNAME="${LOCATION}_${DB_NAME}_${TABLE}.sql"

# Create backups directory if not exists
if [[ ! -e $BASE_DIR ]];then
       mkdir $BASE_DIR
       chown -R postgres:postgres $BASE_DIR
fi

sudo -H -u postgres pg_dump --column-inserts --data-only --table=$TABLE $DB_NAME > $FNAME
sudo gzip $FNAME

In SSMS, "Query" menu item... "Results to"... "Results to File"

Shortcut = CTRL+shift+F

You can set it globally too

"Tools"... "Options"... "Query Results"... "SQL Server".. "Default destination" drop down

Edit: after comment

In SSMS, "Query" menu item... "SQLCMD" mode

This allows you to run "command line" like actions.

A quick test in my SSMS 2008

:OUT c:\foo.txt
SELECT * FROM sys.objects

Edit, Sep 2012

:OUT c:\foo.txt
SET NOCOUNT ON;SELECT * FROM sys.objects

You can use the checked attribute for this:

<input type="radio" checked="checked">

There are two issues with the code in the original question: there should not be a : in the timezone and the format string for "timezone as an offset" is lower case %z not upper %Z.

This works for me in Python v3.6

>>> from datetime import datetime
>>> t = datetime.strptime("2012-11-01T04:16:13-0400", "%Y-%m-%dT%H:%M:%S%z")
>>> print(t)
2012-11-01 04:16:13-04:00

If you want to create a file and write and append data to it many times, then use the below code, it will create file if not exits and will append data if it exists.

 SimpleDateFormat formatter = new SimpleDateFormat("yyyy_MM_dd");
        Date now = new Date();
        String fileName = formatter.format(now) + ".txt";//like 2016_01_12.txt


         try
            {
                File root = new File(Environment.getExternalStorageDirectory()+File.separator+"Music_Folder", "Report Files");
                //File root = new File(Environment.getExternalStorageDirectory(), "Notes");
                if (!root.exists()) 
                {
                    root.mkdirs();
                }
                File gpxfile = new File(root, fileName);


                FileWriter writer = new FileWriter(gpxfile,true);
                writer.append(sBody+"\n\n");
                writer.flush();
                writer.close();
                Toast.makeText(this, "Data has been written to Report File", Toast.LENGTH_SHORT).show();
            }
            catch(IOException e)
            {
                 e.printStackTrace();

            }

Not sure if this is what you're after, but it will loop through the range that you gave it and if it finds an "A" it will remove it from the cell. I'm not sure what oldStr is used for...

Private Sub foo()
Dim myString As String
RowCount = WorksheetFunction.CountA(Range("A:A"))

For i = 2 To RowCount
    myString = Trim(Cells(i, 1).Value)
    If InStr(myString, "A") > 0 Then
        Cells(i, 1).Value = Left(myString, InStr(myString, "A"))
    End If
Next
End Sub

Perhaps the simplest solution uses one of my favorite little-known functions, strcspn():

buffer[strcspn(buffer, "\n")] = 0;

If you want it to also handle '\r' (say, if the stream is binary):

buffer[strcspn(buffer, "\r\n")] = 0; // works for LF, CR, CRLF, LFCR, ...

The function counts the number of characters until it hits a '\r' or a '\n' (in other words, it finds the first '\r' or '\n'). If it doesn't hit anything, it stops at the '\0' (returning the length of the string).

Note that this works fine even if there is no newline, because strcspn stops at a '\0'. In that case, the entire line is simply replacing '\0' with '\0'.

Better way to reset your form with jQuery is Simply trigger a reset event on your form.

$("#btn1").click(function () {
        $("form").trigger("reset");
    });

LDAP is also used to store your credentials in a network security system and retrieve it with your password and decrypted key giving you access to the services.

I struggled with this plugin for a while on Rails, and then someone gemified it obsoleting all the code I had created.

Although it looks like you're not using this in Rails, however if anyone is using it checkout this gem. The source is here --> jQueryFileUpload Rails.

Update:

In order to satisfy the commenter I've updated my answer. Essentially "use this gem, here is the source code" If it disappears then do it the long way.

This may not be what you are looking for but I thought you oughta know the real way to do this. You can use the java.lang.Character class's isUpperCase() to find aout about the case of the character. You can use isDigit() to differentiate between the numbers and letters(This is just FYI :) ). You can then do a toUpperCase() and then do the switch for vowels. This will improve your code quality.

You can provide one or multiple event types separated by a space.

So hover equals mouseenter mouseleave.

This is my sugession:

$("#foo").on("mouseenter mouseleave", function() {
    // do some stuff
});

I have crawled through a lot of blog posts including a few Stack Overflow pots, and I already had everything in place what these posts suggested (see below) when I got this error.

1. My app pool is running under ApplicationPoolIdentity
2. Load user Profile was set to True in Process Model section
3. IIS AppPool\DefaultAppPool has full permissions on temp ASP.NET files folder

Finally I found some clues in the below mentioned blog post. It looks like there is heap contention with the same user account. So I changed the app pool identity to LocalSystem, for the app which is failing with this error - and my app started working fine.

See blog post C# compiler or Visual Basic .Net compilers fail with error code -1073741502 when generating assemblies for your ASP.net site.

Note: LocalSystem account will not have much permissions. In my case my application does not need any special permissions. So I was fine. If your application needs special permissions try configuring a custom account.

With in-built Spark csv, you can get it done easily with new SparkSession object for Spark > 2.0.

val df = spark.
        read.
        option("inferSchema", "false").
        option("header","true").
        option("mode","DROPMALFORMED").
        option("delimiter", ";").
        schema(dataSchema).
        csv("/csv/file/dir/file.csv")
df.show()
df.printSchema()

There are various options you can set.

• header: whether your file includes header line at the top
• inferSchema: whether you want to infer schema automatically or not. Default is true. I always prefer to provide schema to ensure proper datatypes.
• mode: parsing mode, PERMISSIVE, DROPMALFORMED or FAILFAST
• delimiter: to specify delimiter, default is comma(',')

substring is definitely best, but here's one strsplit alternative, since I haven't seen one yet.

> x <- 'hello stackoverflow'
> strsplit(x, '')[[1]][1]
## [1] "h"

or equivalently

> unlist(strsplit(x, ''))[1]
## [1] "h"

And you can paste the rest of the string back together.

> paste0(strsplit(x, '')[[1]][-1], collapse = '')
## [1] "ello stackoverflow"

The problem is in your playerMovement method. You are creating the string name of your room variables (ID1, ID2, ID3):

letsago = "ID" + str(self.dirDesc.values())

However, what you create is just a str. It is not the variable. Plus, I do not think it is doing what you think its doing:

>>>str({'a':1}.values())
'dict_values([1])'

If you REALLY needed to find the variable this way, you could use the eval function:

>>>foo = 'Hello World!'
>>>eval('foo')
'Hello World!'

or the globals function:

class Foo(object):
    def __init__(self):
        super(Foo, self).__init__()
    def test(self, name):
        print(globals()[name])

foo = Foo()
bar = 'Hello World!'
foo.text('bar')

However, instead I would strongly recommend you rethink you class(es). Your userInterface class is essentially a Room. It shouldn't handle player movement. This should be within another class, maybe GameManager or something like that.

“Use let to make a constant and var to make a variable”

Excerpt From: Apple Inc. “The Swift Programming Language.” iBooks. https://itun.es/us/jEUH0.l

Use .onkeydown and cancel the removing with return false;. Like this:

var input = document.getElementById('myInput');

input.onkeydown = function() {
    var key = event.keyCode || event.charCode;

    if( key == 8 || key == 46 )
        return false;
};

Or with jQuery, because you added a jQuery tag to your question:

jQuery(function($) {
  var input = $('#myInput');
  input.on('keydown', function() {
    var key = event.keyCode || event.charCode;

    if( key == 8 || key == 46 )
        return false;
  });
});

Don't use wsgiref for production. Use Apache and mod_wsgi, or something else.

We continue to see these connection resets, sometimes frequently, with wsgiref (the backend used by the werkzeug test server, and possibly others like the Django test server). Our solution was to log the error, retry the call in a loop, and give up after ten failures. httplib2 tries twice, but we needed a few more. They seem to come in bunches as well - adding a 1 second sleep might clear the issue.

We've never seen a connection reset when running through Apache and mod_wsgi. I don't know what they do differently, (maybe they just mask them), but they don't appear.

When we asked the local dev community for help, someone confirmed that they see a lot of connection resets with wsgiref that go away on the production server. There's a bug there, but it is going to be hard to find it.

My open source application BugTracker.NET includes a POP3 client that can parse MIME. Both the POP3 code and the MIME code are from other authors, but you can see how it all fits together in my app.

For the MIME parsing, I use http://anmar.eu.org/projects/sharpmimetools/.

See the file POP3Main.cs, POP3Client.cs, and insert_bug.aspx

The logic is incorrect. It would always return the result of last element in the array.

remIndex = -1;

for (i = 0; i < remSize.length; i++) {      
    if (remSize[i].size == remData.size) {
        remIndex = i
        break;
    }
}

It's often easier to think in the positive sense, and wrap it in a not:

elif not (var1 == 80 or var1 == 443 or (1024 <= var1 <= 65535)):
  # fail

You could of course also go all out and be a bit more object-oriented:

class PortValidator(object):
  @staticmethod
  def port_allowed(p):
    if p == 80: return True
    if p == 443: return True
    if 1024 <= p <= 65535: return True
    return False


# ...
elif not PortValidator.port_allowed(var1):
  # fail

public - The members (Functions & Variables) declared as public can be accessed from anywhere.

private - Private members cannot be accessed from outside the class. This is the default access specifier for a member, i.e if you do not specify an access specifier for a member (variable or function), it will be considered as private. Therefore, string PhoneNumber; is equivalent to private string PhoneNumber.

protected - Protected members can be accessed only from the child classes.

internal - It can be accessed only within the same assembly.

protected internal - It can be accessed within the same assembly as well as in derived class.

I was uninstalled compass 1.0.1 and install compass 0.12.7, this fix problem for me

$ sudo gem uninstall compass
$ sudo gem install compass -v 0.12.7

In some browsers, fonts are set explicit for textareas and inputs, so they don’t inherit the fonts from higher elements. So, I think you need to apply the font styles for each textarea and input in the document as well (not just the body).

One idea might be to add clases to the body, then use CSS to style the document accordingly.

the OOP way to do this in ES5 is to make that variable into a property using the this keyword.

function first(){
    this.nameContent=document.getElementById('full_name').value;
}

function second() {
    y=new first();
    alert(y.nameContent);
}

How about just using str_replace function, if you just want to "Add Classes":

<?php
    echo str_replace( '<li class="', '<li class="myclass ',
        wp_nav_menu(
            array(
                'theme_location'    => 'main_menu',
                'container'         => false,
                'items_wrap'        => '<ul>%3$s</ul>',
                'depth'             => 1,
                'echo'              => false
            )
        )
    );
?>

Tough it is a quick fix for one-level menus or the menus that you want to add Classes to all of <li> elements and is not recommended for more complex menus

Using React Hooks:

You can define a custom Hook that listens to the window resize event, something like this:

import React, { useLayoutEffect, useState } from 'react';

function useWindowSize() {
  const [size, setSize] = useState([0, 0]);
  useLayoutEffect(() => {
    function updateSize() {
      setSize([window.innerWidth, window.innerHeight]);
    }
    window.addEventListener('resize', updateSize);
    updateSize();
    return () => window.removeEventListener('resize', updateSize);
  }, []);
  return size;
}

function ShowWindowDimensions(props) {
  const [width, height] = useWindowSize();
  return <span>Window size: {width} x {height}</span>;
}

The advantage here is the logic is encapsulated, and you can use this Hook anywhere you want to use the window size.

Using React classes:

You can listen in componentDidMount, something like this component which just displays the window dimensions (like <span>Window size: 1024 x 768</span>):

import React from 'react';

class ShowWindowDimensions extends React.Component {
  state = { width: 0, height: 0 };
  render() {
    return <span>Window size: {this.state.width} x {this.state.height}</span>;
  }
  updateDimensions = () => {
    this.setState({ width: window.innerWidth, height: window.innerHeight });
  };
  componentDidMount() {
    window.addEventListener('resize', this.updateDimensions);
  }
  componentWillUnmount() {
    window.removeEventListener('resize', this.updateDimensions);
  }
}

Important improvement! (I added $(this).height('auto'); before measuring height - we should reset it to auto. Then we can use this function on resize)

function equalheight () {
            $('.cont_for_height').each(function(){  

                var highestBox = 0;
                $('.column_height', this).each(function(){

                    var htmlString = $( this ).html()

                    ;


                $(this).height('auto');

                    if($(this).height() > highestBox) 
                       highestBox = $(this).height(); 
                });  

                $('.column_height',this).height(highestBox);

        });  

        }

Your code is passing a function as an argument to find. That function takes an element argument (of type Conversation) and returns void (meaning there is no return value). TypeScript describes this as (element: Conversation) => void'

What TypeScript is saying is that the find function doesn't expect to receive a function that takes a Conversation and returns void. It expects a function that takes a Conversations, a number and a Conversation array, and that this function should return a boolean.

So bottom line is that you either need to change your code to pass in the values to find correctly, or else you need to provide an overload to the definition of find in your definition file that accepts a Conversation and returns void.

For multiple lines the best way I find is to do this:

        IEnumerable<string> lines = new List<string>
        {
            string.Format("{{ line with formatting... {0} }}", id),
            "line 2",
            "line 3"
        };
        StringBuilder sb = new StringBuilder();
        foreach(var line in lines)
            sb.AppendLine(line);

In this way you don't have to clutter the screen with the Environment.NewLine or AppendLine() repeated multiple times. It will also be less error prone than having to remember to type them.

UPDATE 15.3.2017:

I have opened a Django-issue on this and it seems to be preliminary accepted here: https://code.djangoproject.com/ticket/27825

My experience is that when using the Constructor (ORM) class by references with Django 1.10.5 there might be some inconsistencies in the data (i.e. the attributes of the created object may get the type of the input data instead of the casted type of the ORM object property) example:

models

class Payment(models.Model):
     amount_cash = models.DecimalField()

some_test.py - object.create

Class SomeTestCase:
    def generate_orm_obj(self, _constructor, base_data=None, modifiers=None):
        objs = []
        if not base_data:
            base_data = {'amount_case': 123.00}
        for modifier in modifiers:
            actual_data = deepcopy(base_data)
            actual_data.update(modifier)
            # Hacky fix,
            _obj = _constructor.objects.create(**actual_data)
            print(type(_obj.amount_cash)) # Decimal
            assert created
           objs.append(_obj)
        return objs

some_test.py - Constructor()

Class SomeTestCase:
    def generate_orm_obj(self, _constructor, base_data=None, modifiers=None):
        objs = []
        if not base_data:
            base_data = {'amount_case': 123.00}
        for modifier in modifiers:
            actual_data = deepcopy(base_data)
            actual_data.update(modifier)
            # Hacky fix,
            _obj = _constructor(**actual_data)
            print(type(_obj.amount_cash)) # Float
            assert created
           objs.append(_obj)
        return objs

Here is a step by step guide (I think this should come pre-loaded with the add-on):

1. In the top menu of RESTClient -> Headers -> Custom Header
2. In the pop-up box, enter Name: Content-Type and Value: application/x-www-form-urlencoded
3. Check the "Save to favorite" box and click Okay.
   Now you will see a "Headers" section with your newly added data.

4. Then in the Body section, you can enter your data to post like:

   username=test&name=Firstname+Lastname
   

5. Whenever you want to make a post request, from the Headers main menu, select the Content-Type:application/x-www-form-urlencoded item that you added and it should work.

Yes include the first file into the second. That's all.

See an example below,

File1.php :

<?php
  function first($int, $string){ //function parameters, two variables.
    return $string;  //returns the second argument passed into the function
  }
?>

Now Using include (http://php.net/include) to include the File1.php to make its content available for use in the second file:

File2.php :

<?php
  include 'File1.php';
  echo first(1,"omg lol"); //returns omg lol;
?>

The use-case for CORS is simple. Imagine the site alice.com has some data that the site bob.com wants to access. This type of request traditionally wouldn’t be allowed under the browser’s same origin policy. However, by supporting CORS requests, alice.com can add a few special response headers that allows bob.com to access the data. In order to understand it well, please visit this nice tutorial.. How to solve the issue of CORS

I actually wrote a patch to do this a few months ago (after someone asked about it in #angularjs on freenode).

It probably won't be merged, but it's very similar to ngClass: https://github.com/angular/angular.js/pull/4269

Whether it gets merged or not, the existing ng-attr-* stuff is probably suitable for your needs (as others have mentioned), although it might be a bit clunkier than the more ngClass-style functionality that you're suggesting.

I solved it as follows:

1) try to locate ctr1.o and ctri.o files by using find -name ctr1.o

I got the following in my computer: $/usr/lib/i386-linux/gnu

2) Add that path to PATH (also LIBRARY_PATH) environment variable (in order to see which is the name: type env command in the Terminal):

$PATH=/usr/lib/i386-linux/gnu:$PATH
$export PATH

In case you want to pass in a block, say, for a glyphicon button, as in the following:

<%= link_to my_url, class: "stuff" do %>
  <i class="glyphicon glyphicon-inbox></i> Nice glyph-button
<% end %>

Then passing querystrings params could be accomplished through:

<%= link_to url_for(params.merge(my_params: "value")), class: "stuff" do %>
  <i class="glyphicon glyphicon-inbox></i> Nice glyph-button
<% end %>

 <div onScrollCapture={() => this._onScrollEvent()}></div>

 _onScrollEvent = (e)=>{
     const top = e.nativeEvent.target.scrollTop;
     console.log(top); 
}

There are hardware and software watchpoints. They are for reading and for writing a variable. You need to consult a tutorial:

http://www.unknownroad.com/rtfm/gdbtut/gdbwatch.html

To set a watchpoint, first you need to break the code into a place where the varianle i is present in the environment, and set the watchpoint.

watch command is used to set a watchpoit for writing, while rwatch for reading, and awatch for reading/writing.

var array =[2,3,1,9,8];
var minvalue = array[0]; 
for (var i = 0; i < array.length; i++) {
    if(array[i]<minvalue)
    {
        minvalue = array[i];
    }

}
  console.log(minvalue);

On a fresh ubuntu docker image, run

apt-get update
apt-get install net-tools

These can be executed by logging into the docker container or add this to your dockerfile to build an image with the same.

Basically, an integer n is a power of three, if there exists an integer x such that n == 3x.

So to verify that you can use this functions

def is_power_of_three(n)
  return false unless n.positive?

  n == 3**(Math.log10(n)/Math.log10(3)).to_f.round(2)
end

Mac OS Mojave

The accepted answer no longer works. When running the command xcode-select --install it tells you to use "Software Update" to install updates.

In this link is the updated method:

Open a Terminal and then:

cd /Library/Developer/CommandLineTools/Packages/
open macOS_SDK_headers_for_macOS_10.14.pkg

This will open an installation Wizard.

Update 12/2019

After updating to Mojave 10.15.1 it seems that using xcode-select --install works as intended.

Compare its value. It should be between the value of 'a' and 'z', 'A' and 'Z', '0' and '9'

After playing with it for a very long time, this is what I came up with:

    jQuery.fn.scrollTo = function (elem) {
        var b = $(elem);
        this.scrollTop(b.position().top + b.height() - this.height());
    };

and I call it like this

$("#basketListGridHolder").scrollTo('tr[data-uid="' + basketID + '"]');

I saw this solution with T-SQL code and PATINDEX. I like it :-)

CREATE Function [fnRemoveNonNumericCharacters](@strText VARCHAR(1000))
RETURNS VARCHAR(1000)
AS
BEGIN
    WHILE PATINDEX('%[^0-9]%', @strText) > 0
    BEGIN
        SET @strText = STUFF(@strText, PATINDEX('%[^0-9]%', @strText), 1, '')
    END
    RETURN @strText
END

You can also just enter the website and:

1. Choose a repository you have write access to (example URL)
2. Click "Upload files"
3. Drag and drop a folder with files into the "Drag files here to add them to your repository" area.

The same limitation applies here: the folder must contain at least one file inside it.

I'm using sketch.js so after I run the init command for the canvas i change the width and height with jquery. It bases the dimensions on the parent element.

$('#DrawCanvas').sketch().attr('height',$('#DrawCanvas').parent().height()).attr('width',$('#DrawCanvas').parent().width());

The debug compilation is different from the release one, so:

Consider your Project file structure like that [this case if for a Debug assemble]:

src
  |
  debug
      |
      assets
           |
           index.html

You should call index.html into your WebView like:

web.loadUrl("file:///android_asset/index.html");

So forth, for the Release assemble, it should be like:

src
  |
  release
        |
        assets
             |
             index.html

The bellow structure also works, for both compilations [debug and release]:

src
  |
  main
     |
     assets
          |
          index.html

You have to first obtain the Range object. Also, getCell() will not return the value of the cell but instead will return a Range object of the cell. So, use something on the lines of

function email() {

// Opens SS by its ID

var ss = SpreadsheetApp.openById("0AgJjDgtUl5KddE5rR01NSFcxYTRnUHBCQ0stTXNMenc");

// Get the name of this SS

var name = ss.getName();  // Not necessary 

// Read cell 1,1 * Line below does't work *

// var data = Range.getCell(0, 0);
var sheet = ss.getSheetByName('Sheet1'); // or whatever is the name of the sheet 
var range = sheet.getRange(1,1); 
var data = range.getValue();

}

The hierarchy is Spreadsheet --> Sheet --> Range --> Cell.

1) in a query window in SQL Server Management Studio, run the command:

SET SHOWPLAN_ALL ON

2) run your slow query

3) your query will not run, but the execution plan will be returned. store this output

4) run your fast version of the query

5) your query will not run, but the execution plan will be returned. store this output

6) compare the slow query version output to the fast query version output.

7) if you still don't know why one is slower, post both outputs in your question (edit it) and someone here can help from there.

Try wrapping whatever you want to print out in parentheses:

Write-Host ($assoc.Id + "  -  "  + $assoc.Name + "  -  " + $assoc.Owner)

Your code is being interpreted as many parameters being passed to Write-Host. Wrapping it up inside parentheses will concatenate the values and then pass the resulting value as a single parameter.

IF you want to install Maven in Eclipse(Java EE) Indigo Then follow these Steps :

1. Eclipse -> Help -> Install New Software.

There are some wonderful answers on here to this questions that get into all sorts of great detail about interfaces and loosely coupling code, inversion of control and so on. There are some fairly heady discussions, so I'd like to take the opportunity to break things down a bit for understanding why an interface is useful.

When I first started getting exposed to interfaces, I too was confused about their relevance. I didn't understand why you needed them. If we're using a language like Java or C#, we already have inheritance and I viewed interfaces as a weaker form of inheritance and thought, "why bother?" In a sense I was right, you can think of interfaces as sort of a weak form of inheritance, but beyond that I finally understood their use as a language construct by thinking of them as a means of classifying common traits or behaviors that were exhibited by potentially many non-related classes of objects.

For example -- say you have a SIM game and have the following classes:

class HouseFly inherits Insect {
    void FlyAroundYourHead(){}
    void LandOnThings(){}
}

class Telemarketer inherits Person {
    void CallDuringDinner(){}
    void ContinueTalkingWhenYouSayNo(){}
}

Clearly, these two objects have nothing in common in terms of direct inheritance. But, you could say they are both annoying.

Let's say our game needs to have some sort of random thing that annoys the game player when they eat dinner. This could be a HouseFly or a Telemarketer or both -- but how do you allow for both with a single function? And how do you ask each different type of object to "do their annoying thing" in the same way?

The key to realize is that both a Telemarketer and HouseFly share a common loosely interpreted behavior even though they are nothing alike in terms of modeling them. So, let's make an interface that both can implement:

interface IPest {
    void BeAnnoying();
}

class HouseFly inherits Insect implements IPest {
    void FlyAroundYourHead(){}
    void LandOnThings(){}

    void BeAnnoying() {
        FlyAroundYourHead();
        LandOnThings();
    }
}

class Telemarketer inherits Person implements IPest {
    void CallDuringDinner(){}
    void ContinueTalkingWhenYouSayNo(){}

    void BeAnnoying() {
        CallDuringDinner();
        ContinueTalkingWhenYouSayNo();
    }
}

We now have two classes that can each be annoying in their own way. And they do not need to derive from the same base class and share common inherent characteristics -- they simply need to satisfy the contract of IPest -- that contract is simple. You just have to BeAnnoying. In this regard, we can model the following:

class DiningRoom {

    DiningRoom(Person[] diningPeople, IPest[] pests) { ... }

    void ServeDinner() {
        when diningPeople are eating,

        foreach pest in pests
        pest.BeAnnoying();
    }
}

Here we have a dining room that accepts a number of diners and a number of pests -- note the use of the interface. This means that in our little world, a member of the pests array could actually be a Telemarketer object or a HouseFly object.

The ServeDinner method is called when dinner is served and our people in the dining room are supposed to eat. In our little game, that's when our pests do their work -- each pest is instructed to be annoying by way of the IPest interface. In this way, we can easily have both Telemarketers and HouseFlys be annoying in each of their own ways -- we care only that we have something in the DiningRoom object that is a pest, we don't really care what it is and they could have nothing in common with other.

This very contrived pseudo-code example (that dragged on a lot longer than I anticipated) is simply meant to illustrate the kind of thing that finally turned the light on for me in terms of when we might use an interface. I apologize in advance for the silliness of the example, but hope that it helps in your understanding. And, to be sure, the other posted answers you've received here really cover the gamut of the use of interfaces today in design patterns and development methodologies.

I stumbled in the same problem while working on a web api Asp Net Core project. I followed the suggestion to change the reference in my code to:

ConfigurationManager.ConnectionStrings["NameOfTheConnectionString"].ConnectionString

but adding the reference to System.Configuration.dll caused the error "Reference not valid or not supported".

To fix the problem I had to download the package System.Configuration.ConfigurationManager using NuGet (Tools -> Nuget Package-> Manage Nuget packages for the solution)

Redirect the output to DEVNULL:

import os
import subprocess

FNULL = open(os.devnull, 'w')
retcode = subprocess.call(['echo', 'foo'], 
    stdout=FNULL, 
    stderr=subprocess.STDOUT)

It is effectively the same as running this shell command:

retcode = os.system("echo 'foo' &> /dev/null")

Update: This answer applies to the original question relating to python 2.7. As of python >= 3.3 an official subprocess.DEVNULL symbol was added.

retcode = subprocess.call(['echo', 'foo'], 
    stdout=subprocess.DEVNULL, 
    stderr=subprocess.STDOUT)

Simply make an object and extract arguments from that object.

let checkIfNumbersAddToTen = function (a, b) {
return new Promise(function (resolve, reject) {
 let c = parseInt(a)+parseInt(b);
 let promiseResolution = {
     c:c,
     d : c+c,
     x : 'RandomString'
 };
 if(c===10){
     resolve(promiseResolution);
 }else {
     reject('Not 10');
 }
});
};

Pull arguments from promiseResolution.

checkIfNumbersAddToTen(5,5).then(function (arguments) {
console.log('c:'+arguments.c);
console.log('d:'+arguments.d);
console.log('x:'+arguments.x);
},function (failure) {
console.log(failure);
});

(This is pointed out in a comment by Zan Lynx, but I think it deserves an aswer - given that the accepted answer doesn't mention it).

The essential difference between puts(mystr); and printf(mystr); is that in the latter the argument is interpreted as a formatting string. The result will be often the same (except for the added newline) if the string doesn't contain any control characters (%) but if you cannot rely on that (if mystr is a variable instead of a literal) you should not use it.

So, it's generally dangerous -and conceptually wrong- to pass a dynamic string as single argument of printf:

  char * myMessage;
  // ... myMessage gets assigned at runtime, unpredictable content
  printf(myMessage);  // <--- WRONG! (what if myMessage contains a '%' char?) 
  puts(myMessage);    // ok
  printf("%s\n",myMessage); // ok, equivalent to the previous, perhaps less efficient

The same applies to fputs vs fprintf (but fputs doesn't add the newline).

You can create several divs and do that:

<div style="width:100px; height:100px;">
   <div style="position:relative; top:0px; left:0px; width:100px; height:100px; opacity:0.3;"><img src="urltoimage" alt=" " /></div>
   <div style="position:relative; top:0px; left:0px; width:100px; height:100px;"> DIV with no opacity </div>
</div>

I did that couple times... Simple, yet effective...

This solves the issue in the appropriate way

// Merge a row
            ws.Cell("B2").Value = "Merged Row(1) of Range (B2:D3)";
            ws.Range("B2:D3").Row(1).Merge();

I find the currently accepted answer by eidolon too dangerous. The compiler's optimizer might make assumptions about possible values in the enum and you might get garbage back with invalid values. And usually nobody wants to define all possible permutations in flags enums.

As Brian R. Bondy states below, if you're using C++11 (which everyone should, it's that good) you can now do this more easily with enum class:

enum class ObjectType : uint32_t
{
    ANIMAL = (1 << 0),
    VEGETABLE = (1 << 1),
    MINERAL = (1 << 2)
};


constexpr enum ObjectType operator |( const enum ObjectType selfValue, const enum ObjectType inValue )
{
    return (enum ObjectType)(uint32_t(selfValue) | uint32_t(inValue));
}

// ... add more operators here. 

This ensures a stable size and value range by specifying a type for the enum, inhibits automatic downcasting of enums to ints etc. by using enum class, and uses constexpr to ensure the code for the operators gets inlined and thus just as fast as regular numbers.

For people stuck with pre-11 C++ dialects

If I was stuck with a compiler that doesn't support C++11, I'd go with wrapping an int-type in a class that then permits only use of bitwise operators and the types from that enum to set its values:

template<class ENUM,class UNDERLYING=typename std::underlying_type<ENUM>::type>
class SafeEnum
{
public:
    SafeEnum() : mFlags(0) {}
    SafeEnum( ENUM singleFlag ) : mFlags(singleFlag) {}
    SafeEnum( const SafeEnum& original ) : mFlags(original.mFlags) {}

    SafeEnum&   operator |=( ENUM addValue )    { mFlags |= addValue; return *this; }
    SafeEnum    operator |( ENUM addValue )     { SafeEnum  result(*this); result |= addValue; return result; }
    SafeEnum&   operator &=( ENUM maskValue )   { mFlags &= maskValue; return *this; }
    SafeEnum    operator &( ENUM maskValue )    { SafeEnum  result(*this); result &= maskValue; return result; }
    SafeEnum    operator ~()    { SafeEnum  result(*this); result.mFlags = ~result.mFlags; return result; }
    explicit operator bool()                    { return mFlags != 0; }

protected:
    UNDERLYING  mFlags;
};

You can define this pretty much like a regular enum + typedef:

enum TFlags_
{
    EFlagsNone  = 0,
    EFlagOne    = (1 << 0),
    EFlagTwo    = (1 << 1),
    EFlagThree  = (1 << 2),
    EFlagFour   = (1 << 3)
};

typedef SafeEnum<enum TFlags_>  TFlags;

And usage is similar as well:

TFlags      myFlags;

myFlags |= EFlagTwo;
myFlags |= EFlagThree;

if( myFlags & EFlagTwo )
    std::cout << "flag 2 is set" << std::endl;
if( (myFlags & EFlagFour) == EFlagsNone )
    std::cout << "flag 4 is not set" << std::endl;

And you can also override the underlying type for binary-stable enums (like C++11's enum foo : type) using the second template parameter, i.e. typedef SafeEnum<enum TFlags_,uint8_t> TFlags;.

I marked the operator bool override with C++11's explicit keyword to prevent it from resulting in int conversions, as those could cause sets of flags to end up collapsed into 0 or 1 when writing them out. If you can't use C++11, leave that overload out and rewrite the first conditional in the example usage as (myFlags & EFlagTwo) == EFlagTwo.

I am a .NET developer, and have used Git and Visual Studio for years. My strong recommendation is set line endings to true. And do it as early as you can in the lifetime of your Repository.

That being said, I HATE that Git changes my line endings. A source control should only save and retrieve the work I do, it should NOT modify it. Ever. But it does.

What will happen if you don't have every developer set to true, is ONE developer eventually will set to true. This will begin to change the line endings of all of your files to LF in your repo. And when users set to false check those out, Visual Studio will warn you, and ask you to change them. You will have 2 things happen very quickly. One, you will get more and more of those warnings, the bigger your team the more you get. The second, and worse thing, is that it will show that every line of every modified file was changed(because the line endings of every line will be changed by the true guy). Eventually you won't be able to track changes in your repo reliably anymore. It is MUCH easier and cleaner to make everyone keep to true, than to try to keep everyone false. As horrible as it is to live with the fact that your trusted source control is doing something it should not. Ever.

Save it and type the following in a command prompt.

"C:\Windows\Microsoft.NET\Framework\v4.0.30319\vbc.exe" /target:exe /out:"%userprofile%\desktop\ColourText.exe" "%userprofile%\desktop\ColourText.bas" /verbose

A file called ColourText.exe will appear on your desktop. Move it to the Windows folder.

To use you must use two character codes to set colour eg 01 not 1.

ColourText ColourOfText ColourOfTextWhenFinished Text

EG To set blue on white by not passing any text, then red on white text, finishing with blue on grey.

ColourText F1 F1
ColourText F2 71 This is green on white

or

ColourText F1 F1
cls
ColourText F4 F4
Echo Hello
Echo Hello today
ColourText F1 F1

Also the CLS command becomes interesting. Color command without parameters resets all colours to startup colours.

To get the colour code add the following numbers together. Use Calculator in programmers mode. These are hex numbers. They can be added together eg Red + Blue + FG Intensity = 13 = D. As 10+ wasn't used the background will be black. Colour codes MUST be two characters, eg 08 not 8.

FOREGROUND_RED = &H4     '  text color contains red.
FOREGROUND_INTENSITY = &H8     '  text color is intensified.
FOREGROUND_GREEN = &H2     '  text color contains green.
FOREGROUND_BLUE = &H1     '  text color contains blue.
BACKGROUND_BLUE = &H10    '  background color contains blue.
BACKGROUND_GREEN = &H20    '  background color contains green.
BACKGROUND_INTENSITY = &H80    '  background color is intensified.
BACKGROUND_RED = &H40    '  background color contains red.

Jakarta Commons Math has exactly that.

ArithmeticUtils.gcd(int p, int q)

Runtime.getRuntime().exec("java -jar map.jar time.rel test.txt debug");

Messing around with the same answers:

$ git config --global alias.find '!git log --color -p -S '

• ! is needed because other way, git do not pass argument correctly to -S. See this response
• --color and -p helps to show exactly "whatchanged"

Now you can do

$ git find <whatever>

or

$ git find <whatever> --all
$ git find <whatever> master develop

You can also use numpy.invert:

In [1]: import numpy as np

In [2]: import pandas as pd

In [3]: s = pd.Series([True, True, False, True])

In [4]: np.invert(s)
Out[4]: 
0    False
1    False
2     True
3    False

EDIT: The difference in performance appears on Ubuntu 12.04, Python 2.7, NumPy 1.7.0 - doesn't seem to exist using NumPy 1.6.2 though:

In [5]: %timeit (-s)
10000 loops, best of 3: 26.8 us per loop

In [6]: %timeit np.invert(s)
100000 loops, best of 3: 7.85 us per loop

In [7]: %timeit ~s
10000 loops, best of 3: 27.3 us per loop

Python just passes the filename you give it to the operating system, which opens it. If your operating system supports relative paths like main/2091/data.txt (hint: it does), then that will work fine.

You may find that the easiest way to answer a question like this is to try it and see what happens.

I used this recently (thanks to Alnitak):

#!/bin/bash
# activate child monitoring
set -o monitor

# locking subprocess
(while true; do sleep 0.001; done) &
pid=$!

# count, and kill when all done
c=0
function kill_on_count() {
    # you could kill on whatever criterion you wish for
    # I just counted to simulate bash's wait with no args
    [ $c -eq 9 ] && kill $pid
    c=$((c+1))
    echo -n '.' # async feedback (but you don't know which one)
}
trap "kill_on_count" CHLD

function save_status() {
    local i=$1;
    local rc=$2;
    # do whatever, and here you know which one stopped
    # but remember, you're called from a subshell
    # so vars have their values at fork time
}

# care must be taken not to spawn more than one child per loop
# e.g don't use `seq 0 9` here!
for i in {0..9}; do
    (doCalculations $i; save_status $i $?) &
done

# wait for locking subprocess to be killed
wait $pid
echo

From there one can easily extrapolate, and have a trigger (touch a file, send a signal) and change the counting criteria (count files touched, or whatever) to respond to that trigger. Or if you just want 'any' non zero rc, just kill the lock from save_status.

You could also you Point2D Java API class:

public static double distance(double x1, double y1, double x2, double y2)

Example:

double distance = Point2D.distance(3.0, 4.0, 5.0, 6.0);
System.out.println("The distance between the points is " + distance);

The accepted answer offers a solution which requires changing of the underlying data frame. This is not necessary. One can also simply factorise within the aes() call directly or create a vector for that instead.

This is certainly not much different than user Drew Steen's answer, but with the important difference of not changing the original data frame.

level_order <- c('virginica', 'versicolor', 'setosa') #this vector might be useful for other plots/analyses

ggplot(iris, aes(x = factor(Species, level = level_order), y = Petal.Width)) + geom_col()

or

level_order <- factor(iris$Species, level = c('virginica', 'versicolor', 'setosa'))

ggplot(iris, aes(x = level_order, y = Petal.Width)) + geom_col()

or
directly in the aes() call without a pre-created vector:

ggplot(iris, aes(x = factor(Species, level = c('virginica', 'versicolor', 'setosa')), y = Petal.Width)) + geom_col()

I have an example of a full wpf project using this code on my website: Jot the sticky note app.

A number of things can cause session state to mysteriously disappear.

1. Your sessionState timeout has expired
2. You update your web.config or other file type that causes your AppDomain to recycle
3. Your AppPool in IIS recycles
4. You update your site with a lot of files, and ASP.NET proactively destroys your AppDomain to recompile and preserve memory.

-

If you are using IIS 7 or 7.5, here are a few things to look for:

1. By default, IIS sets AppPools to turn themselves off after a period of inactivity.
2. By default, IIS sets AppPools to recycle every 1740 minutes (obviously depending on your root configuration, but that's the default)
3. In IIS, check out the "Advanced Settings" of your AppPool. In there is a property called "Idle Time-out". Set that to zero or to a higher number than the default (20).
4. In IIS, check the "Recycling" settings of your AppPool. Here you can enable or disable your AppPool from recycling. The 2nd page of the wizard is a way to log to the Event Log each type of AppPool shut down.

If you are using IIS 6, the same settings apply (for the most part but with different ways of getting to them), however getting them to log the recycles is more of a pain. Here is a link to a way to get IIS 6 to log AppPool recycle events:

http://web.archive.org/web/20100803114054/http://surrealization.com/sample-code/getnotifiedwhenapppoolrecycles/

-

If you are updating files on your web app, you should expect all session to be lost. That's just the nature of the beast. However, you might not expect it to happen multiple times. If you update 15 or more files (aspx, dll, etc), there is a likelyhood that you will have multiple restarts over a period of time as these pages are recompiled by users accessing the site. See these two links:

http://support.microsoft.com/kb/319947

http://msdn.microsoft.com/en-us/library/system.web.configuration.compilationsection.numrecompilesbeforeapprestart.aspx

Setting the numCompilesBeforeAppRestart to a higher number (or manually bouncing your AppPool) will eliminate this issue.

-

You can always handle Application_SessionStart and Application_SessionEnd to be notified when a session is created or ended. The HttpSessionState class also has an IsNewSession property you can check on any page request to determine if a new session is created for the active user.

-

Finally, if it's possible in your circumstance, I have used the SQL Server session mode with good success. It's not recommended if you are storing a large amount of data in it (every request loads and saves the full amount of data from SQL Server) and it can be a pain if you are putting custom objects in it (as they have to be serializable), but it has helped me in a shared hosting scenario where I couldn't configure my AppPool to not recycle couple hours. In my case, I stored limited information and it had no adverse performance effect. Add to this the fact that an existing user will reuse their SessionID by default and my users never noticed the fact that their in-memory Session was dropped by an AppPool recycle because all their state was stored in SQL Server.

Step-1 Need to find user details by using below query

SQL> select username, account_status from dba_users where username='BOB';

USERNAME                       ACCOUNT_STATUS
------------------------------ --------------------------------
BOB                            EXPIRED

Step-2 Get users password by using below query.

SQL>SELECT 'ALTER USER '|| name ||' IDENTIFIED BY VALUES '''|| spare4 ||';'|| password ||''';' FROM sys.user$ WHERE name='BOB';

ALTER USER BOB IDENTIFIED BY VALUES 'S:9BDD17811E21EFEDFB1403AAB1DD86AB481E;T:602E36430C0D8DF7E1E453;2F9933095143F432';

Step -3 Run Above alter query

SQL> ALTER USER BOB IDENTIFIED BY VALUES 'S:9BDD17811E21EFEDFB1403AAB1DD86AB481E;T:602E36430C0D8DF7E1E453;2F9933095143F432';
User altered.

Step-4 :Check users account status

SQL> select username, account_status from dba_users where username='BOB';
USERNAME                       ACCOUNT_STATUS
------------------------------ --------------------------------
BOB                            OPEN

In short:

defaultdict(int) - the argument int indicates that the values will be int type.

defaultdict(list) - the argument list indicates that the values will be list type.

You can't just change the delimiters from ---- BEGIN SSH2 PUBLIC KEY ---- to -----BEGIN RSA PUBLIC KEY----- and expect that it will be sufficient to convert from one format to another (which is what you've done in your example).

This article has a good explanation about both formats.

What you get in an RSA PUBLIC KEY is closer to the content of a PUBLIC KEY, but you need to offset the start of your ASN.1 structure to reflect the fact that PUBLIC KEY also has an indicator saying which type of key it is (see RFC 3447). You can see this using openssl asn1parse and -strparse 19, as described in this answer.

EDIT: Following your edit, your can get the details of your RSA PUBLIC KEY structure using grep -v -- ----- | tr -d '\n' | base64 -d | openssl asn1parse -inform DER:

    0:d=0  hl=4 l= 266 cons: SEQUENCE          
    4:d=1  hl=4 l= 257 prim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
  265:d=1  hl=2 l=   3 prim: INTEGER           :010001

To decode the SSH key format, you need to use the data format specification in RFC 4251 too, in conjunction with RFC 4253:

   The "ssh-rsa" key format has the following specific encoding:

      string    "ssh-rsa"
      mpint     e
      mpint     n

For example, at the beginning, you get 00 00 00 07 73 73 68 2d 72 73 61. The first four bytes (00 00 00 07) give you the length. The rest is the string itself: 73=s, 68=h, ... -> 73 73 68 2d 72 73 61=ssh-rsa, followed by the exponent of length 1 (00 00 00 01 25) and the modulus of length 256 (00 00 01 00 7f ...).

I think your particular problem isn't how to use Glyphicons but understanding how Bootstrap files work together.

Bootstrap requires a specific file structure to work. I see from your code you have this:

<link href="bootstrap.css" rel="stylesheet" media="screen">

Your Bootstrap.css is being loaded from the same location as your page, this would create a problem if you didn't adjust your file structure.

But first, let me recommend you setup your folder structure like so:

/css      <-- Bootstrap.css here
/fonts    <-- Bootstrap fonts here
/img
/js       <-- Bootstrap JavaScript here
index.html

If you notice, this is also how Bootstrap structures its files in its download ZIP.

You then include your Bootstrap file like so:

<link href="css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="./css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="/css/bootstrap.css" rel="stylesheet" media="screen">

Depending on your server structure or what you're going for.

The first and second are relative to your file's current directory. The second one is just more explicit by saying "here" (./) first then css folder (/css).

The third is good if you're running a web server, and you can just use relative to root notation as the leading "/" will be always start at the root folder.

So, why do this?

Bootstrap.css has this specific line for Glyphfonts:

@font-face {
    font-family: 'Glyphicons Halflings';
    src: url('../fonts/glyphicons-halflings-regular.eot');
    src: url('../fonts/glyphicons-halflings-regular.eot?#iefix') format('embedded-opentype'), url('../fonts/glyphicons-halflings-regular.woff') format('woff'), url('../fonts/glyphicons-halflings-regular.ttf') format('truetype'), url('../fonts/glyphicons-halflings-regular.svg#glyphicons-halflingsregular') format('svg');
}

What you can see is that that Glyphfonts are loaded by going up one directory ../ and then looking for a folder called /fonts and THEN loading the font file.

The URL address is relative to the location of the CSS file. So, if your CSS file is at the same location like this:

/fonts
Bootstrap.css
index.html

The CSS file is going one level deeper than looking for a /fonts folder.

So, let's say the actual location of these files are:

C:\www\fonts
C:\www\Boostrap.css
C:\www\index.html

The CSS file would technically be looking for a folder at:

C:\fonts

but your folder is actually in:

C:\www\fonts

So see if that helps. You don't have to do anything 'special' to load Bootstrap Glyphicons, except make sure your folder structure is set up appropriately.

When you get that fixed, your HTML should simply be:

<span class="glyphicon glyphicon-comment"></span>

Note, you need both classes. The first class glyphicon sets up the basic styles while glyphicon-comment sets the specific image.

You can use simple loops to check two strings are equal. .But ideally you can use something like return s1==s2

s1 = 'hello'
s2 = 'hello'

a = []
for ele in s1:
    a.append(ele)
for i in range(len(s2)):
    if a[i]==s2[i]:
        a.pop()
if len(a)>0:
    return False
else:
    return True

If you have a 64-bit version of SQL Developer, but for some reason your default JDK is a 32-bit JDK (e.g. if you develop an Eclipse RCP application which requires a 32-bit JDK), then you have to set the value of the SetJavaHome property in the product.conf file to a 64-bit version of JDK in order to run the SQL Developer. For example:

SetJavaHome C:\Program Files\Java\jdk1.7.0_80

The product.conf file is in my case located in the following directory:

C:\Users\username\AppData\Roaming\sqldeveloper\1.0.0.0.0

The solution described above worked in my case. The solutions of @evgenyl and @FGreg did not work in my case.

A very common usecase of calc is take 100% width and adding some margin around the element.

One can do so with:

@someMarginVariable = 15px;

margin: @someMarginVariable;
width: calc(~"100% - "@someMarginVariable*2);
width: -moz-calc(~"100% - "@someMarginVariable*2);
width: -webkit-calc(~"100% - "@someMarginVariable*2);

Most easy way..

//div[@class="Test"]

Assuming you want to find <div class="Test"> as described.

You can set the line height on the text, for example within the active class:

.active {
    ...
    line-height: 2em;
    ....
}

First off, RangeToHTML. The script calls it like a method, but it isn't. It's a popular function by MVP Ron de Bruin. Coincidentally, that links points to the exact source of the script you posted, before those few lines got b?u?t?c?h?e?r?e?d? modified.

On with Range.SpecialCells. This method operates on a range and returns only those cells that match the given criteria. In your case, you seem to be only interested in the visible text cells. Importantly, it operates on a Range, not on HTML text.

For completeness sake, I'll post a working version of the script below. I'd certainly advise to disregard it and revisit the excellent original by Ron the Bruin.

There the problem : I need to generate html code from the contain of a given div. Then, I have to put this raw html code in a textarea. When I use the function $(textarea).val() like this :

$(textarea).val("some html like < input type='text' value='' style="background: url('http://www.w.com/bg.gif') repeat-x center;" /> bla bla");

or

$('#idTxtArGenHtml').val( $('idDivMain').html() );

I had problem with some special character ( & ' " ) when they are between quot. But when I use the function : $(textarea).html() the text is ok.

There an example form :

<FORM id="idFormContact" name="nFormContact" action="send.php" method="post"  >
    <FIELDSET id="idFieldContact" class="CMainFieldset">
        <LEGEND>Test your newsletter&raquo; </LEGEND> 
        <p>Send to &agrave; : <input id='idInpMailList' type='text' value='[email protected]' /></p>
        <FIELDSET  class="CChildFieldset">
            <LEGEND>Subject</LEGEND>
            <LABEL for="idNomClient" class="CInfoLabel">Enter the subject: *&nbsp</LABEL><BR/>
          <INPUT value="" name="nSubject" type="text" id="idSubject" class="CFormInput" alt="Enter the Subject" ><BR/>
    </FIELDSET>
    <FIELDSET  class="CChildFieldset">
        <INPUT id="idBtnGen" type="button" value="Generate" onclick="onGenHtml();"/>&nbsp;&nbsp;
          <INPUT id="idBtnSend" type="button" value="Send" onclick="onSend();"/><BR/><BR/>
            <LEGEND>Message</LEGEND>
                <LABEL for="idTxtArGenHtml" class="CInfoLabel">Html code : *&nbsp</LABEL><BR/>
                <span><TEXTAREA  name="nTxtArGenHtml" id="idTxtArGenHtml" width='100%' cols="69" rows="300" alt="enter your message" ></TEXTAREA></span>
        </FIELDSET>
    </FIELDSET>
</FORM>

And javascript/jquery code that don't work to fill the textarea is :

function onGenHtml(){
  $('#idTxtArGenHtml').html( $("#idDivMain").html()  );
}

Finaly the solution :

function onGenHtml(){
  $('#idTxtArGenHtml').html( $("#idDivMain").html() );
  $('#idTxtArGenHtml').parent().replaceWith( '<span>'+$('#idTxtArGenHtml').parent().html()+'</span>');
}

The trick is wrap your textarea with a span tag to help with the replaceWith function. I'm not sure if it's very clean, but it's work perfect too add raw html code in a textarea.

If you are using underscore.js library then object/array operations become simple.

In your case _.has method can be used. Example:

yourArray = {age: "10"}

_.has(yourArray, "age")

returns true

But,

_.has(yourArray, "invalidKey")

returns false

You can use string.Format("{0:c}", value).

The question title says "How can I simulate an anchor click in jQuery?". Well, you can use the "trigger" or "triggerHandler" methods, like so:

<script type="text/javascript" src="path/to/jquery.js"></script>
<script type="text/javascript" src="path/to/thickbox.js"></script>
<script type="text/javascript">
$(function() {
    $('#btn').click(function() {
        $('#thickboxId').triggerHandler('click');
    })
})
</script>
...
<input id="btn" type="button" value="Click me">
<a id="thickboxId" href="myScript.php" class="thickbox" title="">Link</a>

Not tested, this actual script, but I've used trigger et al before, and they worked a'ight.

UPDATE
triggerHandler doesn't actually do what the OP wants. I think 1421968 provides the best answer to this question.

Not sure if there are still people looking for an explanation and a solution. The comments above say it all on the differences between TRUE / FALSE / 1 / 0.
I would just like to bring my 2 cents for the way to display the actual value.

BOOLEAN

If you're working with a Boolean datatype, you're looking for a TRUE vs. FALSE result; if you store it in MySQL, it will be stored as 1 resp. 0 (if I'm not mistaking, this is the same in your server's memory).

So to display the the value in PHP, you need to check if it is true (1) or false (0) and display whatever you want: "TRUE" or "FALSE" or possibly "1" or "0".
Attention, everything bigger (or different) than 0 will also be considered as TRUE in PHP. E.g.: 2, "abc", etc. will all return TRUE.

BIT, TINYINT

If you're working with a number datatype, the way it is stored is the same.
To display the value, you need to tell PHP to handle it as a number. The easiest way I found is to multiply it by 1.

This is an old thread, but purely using os.system, the following's a valid way of accessing the data returned by the ps call. Note: it does use a pipe to write the data to a file on disk. And OP didn't specifically ask for a solution using os.system.

>>> os.system("ps > ~/Documents/ps.txt")
0    #system call is processed.
>>> os.system("cat ~/Documents/ps.txt")
  PID TTY          TIME CMD
 9927 pts/0    00:00:00 bash
10063 pts/0    00:00:00 python
12654 pts/0    00:00:00 sh
12655 pts/0    00:00:00 ps
0

accordingly,

>>> os.system("ps -p 10063 -o time --no-headers > ~/Documents/ps.txt")
0
>>> os.system("cat ~/Documents/ps.txt")
00:00:00
0

No idea why they are all returning zeroes though.

The calculation occurs immediately since the calculation call is bound in the template, which displays its result when quantity changes.

Instead you could try the following approach. Change your markup to the following:

<div ng-controller="myAppController" style="text-align:center">
  <p style="font-size:28px;">Enter Quantity:
      <input type="text" ng-model="quantity"/>
  </p>
  <button ng-click="calculateQuantity()">Calculate</button>
  <h2>Total Cost: Rs.{{quantityResult}}</h2>
</div>

Next, update your controller:

myAppModule.controller('myAppController', function($scope,calculateService) {
  $scope.quantity=1;
  $scope.quantityResult = 0;

  $scope.calculateQuantity = function() {
    $scope.quantityResult = calculateService.calculate($scope.quantity, 10);
  };
});

Here's a JSBin example that demonstrates the above approach.

The problem with this approach is the calculated result remains visible with the old value till the button is clicked. To address this, you could hide the result whenever the quantity changes.

This would involve updating the template to add an ng-change on the input, and an ng-if on the result:

<input type="text" ng-change="hideQuantityResult()" ng-model="quantity"/>

and

<h2 ng-if="showQuantityResult">Total Cost: Rs.{{quantityResult}}</h2>

In the controller add:

$scope.showQuantityResult = false;

$scope.calculateQuantity = function() {
  $scope.quantityResult = calculateService.calculate($scope.quantity, 10);
  $scope.showQuantityResult = true;
};

$scope.hideQuantityResult = function() {
  $scope.showQuantityResult = false;
}; 

These updates can be seen in this JSBin demo.

Or, if you don't need else clause:

[ "$x" == "valid" ] && echo "x has the value 'valid'"

SET foreign_key_checks = 0;
DROP TABLE IF EXISTS a,b,c;
SET foreign_key_checks = 1;

Then you do not have to worry about dropping them in the correct order, nor whether they actually exist.

N.B. this is for MySQL only (as in the question). Other databases likely have different methods for doing this.

You didnt specify the platform you use, so I assume it's a Mac ;-)

What I do is use a proxy. I use SquidMan, a standalone implementation of Squid

I start SquidMan on the Mac, then on the iPhone I enter the Proxy params in the General/Wifi Settings.

Then I can watch the HTTP trafic in the Console App, looking at the squid-access.log

If I need more infos, I switch to tcpdump, but I suppose WireShark should work too.

7-Zip wants relative paths in the list file otherwise it will store only the filenames, causing duplicate file name error.

Assuming that your list contains full path names:

• Edit the list file to remove drive prefix, C:\
• Make sure you are in the root of the drive when you run 7Z to use the above list file.
• Then it will store the paths and won't complain of the duplicate name. It wants relative paths in the list file.

If your list file has paths relative to another folder, you should be running 7Z from that folder.

Update: I noticed from another post above that the new 7-Zip has an -spf option that doesn't require the above steps. Not tested it yet but my steps are for earlier versions that do not have this option.

You can refer to this answer - https://stackoverflow.com/a/24105062/3629912

It worked for me everytime.

adb shell dumpsys window InputMethod | grep "mHasSurface"

It will return true, if software keyboard is visible.

You can do

$('#yourelement').ready(function() {

});

Please note that this will only work if the element is present in the DOM when being requested from the server. If the element is being dynamically added via JavaScript, it will not work and you may need to look at the other answers.

Just got the same issue after installing Developer Tools Microsoft ASP.NET and Web Tools 2015 (Beta7). I tried to reinstall ASP.NET Project Templates but it didn't help.

While looking into "Add / remove programs" -> "Visual 2015" -> "Modify" , I found the "Web developer tools" unchecked. This SO answer helps me to figure this.

After reinstalling this, everything reappears

I am using a .Net Core 2.1 Web Application and could not get a single answer here to work. I either got a blank parameter (if the method was called at all) or a 500 server error. I started playing with every possible combination of answers and finally got a working result.

In my case the solution was as follows:

Script - stringify the original array (without using a named property)

    $.ajax({
        type: 'POST',
        contentType: 'application/json; charset=utf-8',
        url: mycontrolleraction,
        data: JSON.stringify(things)
    });

And in the controller method, use [FromBody]

    [HttpPost]
    public IActionResult NewBranch([FromBody]IEnumerable<Thing> things)
    {
        return Ok();
    }

Failures include:

• Naming the content

  data: { content: nodes }, // Server error 500

• Not having the contentType = Server error 500

Notes

• dataType is not needed, despite what some answers say, as that is used for the response decoding (so not relevant to the request examples here).
• List<Thing> also works in the controller method

You're missing comma (,) inbetween:

>>> ((1,2) (2,3))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'tuple' object is not callable

Put comma:

>>> ((1,2), (2,3))
((1, 2), (2, 3))

You can either try Restful service startup kit of codeples or use fiddler to test your other http verbs

Sorry not sure what was going on this worked in the end:

<VirtualHost *> 
    ServerName example.com
    DocumentRoot /var/www/html/mjp

    <Directory "/var/www/html/ncn">

The marked answer is fine, but it makes the image stretched. In my case I had a small tile image that I wanted repeat not stretch. And the following code was the best way for me to solve the black background issue:

UIImage *tileImage = [UIImage imageNamed:@"myTileImage"];
UIColor *color = [UIColor colorWithPatternImage:tileImage];
UIView  *backgroundView = [[UIView alloc] initWithFrame:self.view.frame];
[backgroundView setBackgroundColor:color];
//backgroundView.alpha = 0.1; //use this if you want to fade it away.
[self.view addSubview:backgroundView];
[self.view sendSubviewToBack:backgroundView];

There is no direct shortcut for such operation in IntelliJ IDEA 14 but you can install the plugin and set it the keyboard shortcut to the function that called "Scroll From Source" in keymap settings.

Your can do it like this in short hands.

        int[,] values=new int[2,3]{{2,4,5},{4,5,2}};

        for (int i = 0; i < values.GetLength(0); i++)
        {
            for (int k = 0; k < values.GetLength(1); k++) {
                Console.Write(values[i,k]);
            }

            Console.WriteLine();
        }

I can't find anything that deals with clock times exactly, so I'd just use some functions from package:lubridate and work with seconds-since-midnight:

require(lubridate)
clockS = function(t){hour(t)*3600+minute(t)*60+second(t)}
plot(clockS(times),val)

You might then want to look at some of the axis code to figure out how to label axes nicely.

You can create a subclass of Application and store your shared object there. The Application object should exist for the lifetime of your app as long as there is some active component.

From your activities, you can access the application object via getApplication().

Try this coding

<div>
    <iframe id='iframe2' src="Mypage.aspx" frameborder="0" style="overflow: hidden; height: 100%;
        width: 100%; position: absolute;"></iframe>
</div>

I thought about using the (ngModelChange) method, then thought about the FormBuilder method, and finally settled on a variation of Method 3. This saves decorating the template with extra attributes and automatically picks up changes to the model - reducing the possibility of forgetting something with Method 1 or 2.

Simplifying Method 3 a bit...

oldPerson = JSON.parse(JSON.stringify(this.person));

ngDoCheck(): void {
    if (JSON.stringify(this.person) !== JSON.stringify(this.oldPerson)) {
        this.doSomething();
        this.oldPerson = JSON.parse(JSON.stringify(this.person));
    }
}

You could add a timeout to only call doSomething() after x number of milliseconds to simulate debounce.

oldPerson = JSON.parse(JSON.stringify(this.person));

ngDoCheck(): void {
    if (JSON.stringify(this.person) !== JSON.stringify(this.oldPerson)) {
        if (timeOut) clearTimeout(timeOut);
        let timeOut = setTimeout(this.doSomething(), 2000);
        this.oldPerson = JSON.parse(JSON.stringify(this.person));
    }
}

I spent the better part of a day fiddling with this problem. Turned out the RowBackground Property on the DataGrid - which I had set - was overriding all attempts to change it in . As soon as I deleted it, everything worked. (Same goes for Foreground set in DataGridTextColumn, by the way).
