Right-click the project, select Properties then under 'Configuration properties | Linker | Input | Ignore specific Library and write msvcrtd.lib

This problem explained in MSDN Library and as I understand installing Microsoft's Redistributable Package can help.

But sometimes the following solution can be used (as developer's side solution):

In your Visual Studio, open Project properties -> Configuration properties -> C/C++ -> Code generation and change option Runtime Library to /MT instead of /MD

<div class="ai">a b c d e f</div> // something like ~100px
<div class="ai">a b c d e</div> // ~80
<div class="ai">a b c d</div> // ~60 

<script>

function _reWidthAll_div(classname) {

var _maxwidth = 0;

    $(classname).each(function(){

    var _width = $(this).width();

    _maxwidth = (_width >= _maxwidth) ? _width : _maxwidth; // define max width
    });    

$(classname).width(_maxwidth); // return all div same width

}

_reWidthAll_div('.ai');

</script>

If you are on android and using threetenbp you can use DateTimeUtils instead.

ex:

Date date = DateTimeUtils.toDate(localDateTime.atZone(ZoneId.systemDefault()).toInstant());

you can't use Date.from since it's only supported on api 26+

I suggest to approximate locally the Earth surface as a sphere with radius given by the WGS84 ellipsoid at the given latitude. I suspect that the exact computation of latMin and latMax would require elliptic functions and would not yield an appreciable increase in accuracy (WGS84 is itself an approximation).

My implementation follows (It's written in Python; I have not tested it):

# degrees to radians
def deg2rad(degrees):
    return math.pi*degrees/180.0
# radians to degrees
def rad2deg(radians):
    return 180.0*radians/math.pi

# Semi-axes of WGS-84 geoidal reference
WGS84_a = 6378137.0  # Major semiaxis [m]
WGS84_b = 6356752.3  # Minor semiaxis [m]

# Earth radius at a given latitude, according to the WGS-84 ellipsoid [m]
def WGS84EarthRadius(lat):
    # http://en.wikipedia.org/wiki/Earth_radius
    An = WGS84_a*WGS84_a * math.cos(lat)
    Bn = WGS84_b*WGS84_b * math.sin(lat)
    Ad = WGS84_a * math.cos(lat)
    Bd = WGS84_b * math.sin(lat)
    return math.sqrt( (An*An + Bn*Bn)/(Ad*Ad + Bd*Bd) )

# Bounding box surrounding the point at given coordinates,
# assuming local approximation of Earth surface as a sphere
# of radius given by WGS84
def boundingBox(latitudeInDegrees, longitudeInDegrees, halfSideInKm):
    lat = deg2rad(latitudeInDegrees)
    lon = deg2rad(longitudeInDegrees)
    halfSide = 1000*halfSideInKm

    # Radius of Earth at given latitude
    radius = WGS84EarthRadius(lat)
    # Radius of the parallel at given latitude
    pradius = radius*math.cos(lat)

    latMin = lat - halfSide/radius
    latMax = lat + halfSide/radius
    lonMin = lon - halfSide/pradius
    lonMax = lon + halfSide/pradius

    return (rad2deg(latMin), rad2deg(lonMin), rad2deg(latMax), rad2deg(lonMax))

EDIT: The following code converts (degrees, primes, seconds) to degrees + fractions of a degree, and vice versa (not tested):

def dps2deg(degrees, primes, seconds):
    return degrees + primes/60.0 + seconds/3600.0

def deg2dps(degrees):
    intdeg = math.floor(degrees)
    primes = (degrees - intdeg)*60.0
    intpri = math.floor(primes)
    seconds = (primes - intpri)*60.0
    intsec = round(seconds)
    return (int(intdeg), int(intpri), int(intsec))

//get dimensions 
var height = $(window).height();
var width = $(window).width();

//refresh on resize
$(window).resize(function() {
  location.reload(true)
});

not sure if you wanted to tinker with the dimensions of elements or actually refresh the page. so here a bunch of different things pick what you want. you can even put the height and width in the resize event if you really wanted.

IE.Document.getElementById("dgTime").getElementsByTagName("a")(0).Click

EDIT: to loop through the collection (items should appear in the same order as they are in the source document)

Dim links, link 

Set links = IE.Document.getElementById("dgTime").getElementsByTagName("a")

'For Each loop
For Each link in links
    link.Click
Next link

'For Next loop
Dim n, i
n = links.length
For i = 0 to n-1 Step 2
    links(i).click
Next I

Unfortunately to be able to use the extension modules provided by others you'll be forced to use the official compiler to compile Python. These are:

• Visual Studio 2008 for Python 2.7. See: https://docs.python.org/2.7/using/windows.html#compiling-python-on-windows

• Visual Studio 2010 for Python 3.4. See: https://docs.python.org/3.4/using/windows.html#compiling-python-on-windows

Alternatively, you can use MinGw to compile extensions in a way that won't depend on others.

See: https://docs.python.org/2/install/#gnu-c-cygwin-MinGW or https://docs.python.org/3.4/install/#gnu-c-cygwin-mingw

This allows you to have one compiler to build your extensions for both versions of Python, Python 2.x and Python 3.x.

Yahoo! This is really possible. I found it.

For Bottom Border:

For Top Border:

div {box-shadow: 0px 3px 0px red inset; }

In IIS Manager click on your site. You need to be "in feature view" (rather than "content view")

In the IIS section of "feature view" choose the so-called feature "authentication" and doulbe click it. Here you can enable Windows Authentication. This is also possible (by i think in one of the suggestions in the thread) by a setting in the web.config ( ...)

But maybe you have a web.config you do not want to scrue too much around with. Then this thread wouldnt be too much help, which is why i added this answer.

The most common solution that I have seen to enum's in PHP has been to create a generic enum class and then extend it. You might take a look at this.

UPDATE: Alternatively, I found this from phpclasses.org.

I had this same issue , but after a couple of research I fond it out it's quite simple to do,

Locate this URL in your Codeigniter project: application/helpers/util_helper.php

add this below code

//you can define any kind of function but I have queried database in my case

//check if the function exist
 if (!function_exists('yourfunctionname')) {
    function yourfunctionname($param (if neccesary)) {
        
        //get the instance
        $ci = & get_instance();
    
        // write your query with the instance class

        $data =  $ci->db->select('*');
        $data =  $ci->db->from('table');  
        $data =  $ci->db->where('something', 'something');

        //you can return anythting

        $data =  $ci->db->get()->num_rows(); 

        if ($data > 0) {
            return $data;
        }  else {
            return 0;
        }  
    }
}

To adjust the length of the samples:

set key samplen X

(default is 4)

To adjust the vertical spacing of the samples:

set key spacing X

(default is 1.25)

and (for completeness), to adjust the fontsize:

set key font "<face>,<size>"

(default depends on the terminal)

And of course, all these can be combined into one line:

set key samplen 2 spacing .5 font ",8"

Note that you can also change the position of the key using set key at <position> or any one of the pre-defined positions (which I'll just defer to help key at this point)

You can write:

python
import keras
keras.__version__

They look pretty much the same on Python 3.2.

As gnibbler pointed out, the first doesn't need to lookup dict, which should make it a tiny bit faster.

>>> def literal():
...   d = {'one': 1, 'two': 2}
...

...   d = dict(one='1', two='2')
...
>>> import dis
>>> dis.dis(literal)
  2           0 BUILD_MAP                2
              3 LOAD_CONST               1 (1)

             20 LOAD_CONST               0 (None)
             23 RETURN_VALUE

              6 LOAD_CONST               2 ('1')
              9 LOAD_CONST               3 ('two')
             12 LOAD_CONST               4 ('2')

Very good question indeed. I just tried for myself.

public class IsInstanceOfTest {

    public static void main(final String[] args) {

        String s;

        s = "";

        System.out.println((s instanceof String));
        System.out.println(String.class.isInstance(s));

        s = null;

        System.out.println((s instanceof String));
        System.out.println(String.class.isInstance(s));
    }
}

Prints

true
true
false
false

JLS / 15.20.2. Type Comparison Operator instanceof

At run time, the result of the instanceof operator is true if the value of the RelationalExpression is not null and the reference could be cast to the ReferenceType without raising a ClassCastException. Otherwise the result is false.

API / Class#isInstance(Object)

If this Class object represents an interface, this method returns true if the class or any superclass of the specified Object argument implements this interface; it returns false otherwise. If this Class object represents a primitive type, this method returns false.

You can try Wolfram Alpha as in this example based on your input:

http://www.wolframalpha.com/input/?i=((A%20OR%20B)%20AND%20(NOT%20B%20AND%20C)%20OR%20C)&t=crmtb01&f=rc

You can use this for direct find value via params name.

const urlParams = new URLSearchParams(window.location.search);
const myParam = urlParams.get('myParam');

The problem with your code is that the your script is executed prior to the html element being available. Because of the that var comment is an empty array.

So you should move your script after the html element is available.

Also, getElementsByClassName returns html collection, so if you need to add event Listener to an element, you will need to do something like following

comment[0].addEventListener('click' , showComment , false ) ; 

If you want to add event listener to all the elements, then you will need to loop through them

for (var i = 0 ; i < comment.length; i++) {
   comment[i].addEventListener('click' , showComment , false ) ; 
}

Sure, use the .format method. E.g.,

print('{:10s} {:3d}  {:7.2f}'.format('xxx', 123, 98))
print('{:10s} {:3d}  {:7.2f}'.format('yyyy', 3, 1.0))
print('{:10s} {:3d}  {:7.2f}'.format('zz', 42, 123.34))

will print

xxx        123    98.00
yyyy         3     1.00
zz          42   123.34

You can adjust the field sizes as desired. Note that .format works independently of print to format a string. I just used print to display the strings. Brief explanation:

10s format a string with 10 spaces, left justified by default

3d format an integer reserving 3 spaces, right justified by default

7.2f format a float, reserving 7 spaces, 2 after the decimal point, right justfied by default.

There are many additional options to position/format strings (padding, left/right justify etc), String Formatting Operations will provide more information.

Update for f-string mode. E.g.,

text, number, other_number = 'xxx', 123, 98
print(f'{text:10} {number:3d}  {other_number:7.2f}')

For right alignment

print(f'{text:>10} {number:3d}  {other_number:7.2f}')

The other answers are generally correct and all outdated. Do use java.time, the modern Java date and time API, for your date and time work. With java.time your job has also become a lot easier compared to the situation when this question was asked in February 2014.

    String dateTimeString = "2014-01-16T10:25:00";
    LocalDateTime dateTime = LocalDateTime.parse(dateTimeString);
    LocalDateTime now = LocalDateTime.now(ZoneId.systemDefault());

    if (dateTime.isBefore(now)) {
        System.out.println(dateTimeString + " is in the past");
    } else if (dateTime.isAfter(now)) {
        System.out.println(dateTimeString + " is in the future");
    } else {
        System.out.println(dateTimeString + " is now");
    }

When running in 2020 output from this snippet is:

2014-01-16T10:25:00 is in the past

Since your string doesn’t inform of us any time zone or UTC offset, we need to know what was understood. The code above uses the device’ time zone setting. For a known time zone use like for example ZoneId.of("Asia/Ulaanbaatar"). For UTC specify ZoneOffset.UTC.

I am exploiting the fact that your string is in ISO 8601 format. The classes of java.time parse the most common ISO 8601 variants without us having to give any formatter.

Question: For Android development doesn’t java.time require Android API level 26?

java.time works nicely on both older and newer Android devices. It just requires at least Java 6.

• In Java 8 and later and on newer Android devices (from API level 26) the modern API comes built-in.
• In non-Android Java 6 and 7 get the ThreeTen Backport, the backport of the modern classes (ThreeTen for JSR 310; see the links at the bottom).
• On (older) Android use the Android edition of ThreeTen Backport. It’s called ThreeTenABP. And make sure you import the date and time classes from org.threeten.bp with subpackages.

The nuclear option:

$("#yourtableid").html("");

Destroys everything inside of #yourtableid. Be careful with your selectors, as it will destroy any html in the selector you pass!

You need to be using a Maven plugin for Eclipse in order to do this properly. The m2e plugin is built into the latest version of Eclipse, and does a decent if not perfect job of integrating Maven into the IDE. You will want to create your project as a 'Maven Project'. Alternatively you can import an existing Maven POM into your workspace to automatically create projects. Once you have your Maven project in the IDE, simply open up the POM and add your dependency to it.

Now, if you do not have a Maven plugin for Eclipse, you will need to get the jar(s) for the dependency in question and manually add them as classpath references to your project. This could get unpleasant as you will need not just the top level JAR, but all its dependencies as well.

Basically, I recommend you get a decent Maven plugin for Eclipse and let it handle the dependency management for you.

I noticed it myself, and found the files inside the backup folder. You can check where it is using Menu:Settings -> Preferences -> Backup. Note : My NPP installation is portable, and on Windows, so YMMV.

Ok, something odd is happening here. To make this work, do NOT need to make any configuration changes in /etc/mysql/my.cnf . All you need to do is to restart the current mysql service in terminal:

sudo service mysql restart

Then if I want to "recreate" the bug, I simply restart the apache service:

sudo service apache2 restart

Which can then be fixed again by entering the following command:

sudo service mysql restart

So, it appears that the apache2 is doing something to not allow this feature when it starts up (which is then reversed/corrected if restart the mysql service).

Valid in Debian based distributions.

service mysqld restart
service httpd restart

Valid in RedHat based distributions

I had the same problem. However, nothing worked for me. I solved the issue by adding

exit 0

to my code. The problem was that while I was doing copying of the files, sometimes the last file could not be found, and the bat returned a non-zero value.

Hope this helps someone!

You could use the following to replace the first occurrence of a word within the body of the page:

var replaced = $("body").html().replace('-9o0-9909','The new string');
$("body").html(replaced);

If you wanted to replace all occurrences of a word, you need to use regex and declare it global /g:

var replaced = $("body").html().replace(/-1o9-2202/g,'The ALL new string');
$("body").html(replaced);

If you wanted a one liner:

$("body").html($("body").html().replace(/12345-6789/g,'<b>abcde-fghi</b>'));

You are basically taking all of the HTML within the <body> tags of the page into a string variable, using replace() to find and change the first occurrence of the found string with a new string. Or if you want to find and replace all occurrences of the string introduce a little regex to the mix.

As mentioned in several places, I'm also not able to get the req.session.destroy() function to work correctly.

This is my work around .. seems to do the trick, and still allows req.flash to be used

req.session = {};

If you delete or set req.session = null; , seems then you can't use req.flash

You are specifying .fixedbutton in your CSS (a class) and specifying the id on the element itself.

Change your CSS to the following, which will select the id fixedbutton

#fixedbutton {
    position: fixed;
    bottom: 0px;
    right: 0px; 
}

Here's a jsFiddle courtesy of JoshC.

GET (multiple parameters):

or

or

curl  "http://localhost:3000/action?result1=gh&result2=ghk"

or

Don't know for sure, but it sounds like it is still submitting. I quick solution would be to change your (guessing at your code here):

<input type="submit" value="Submit" onclick="checkform()">

to a button:

<input type="button" value="Submit" onclick="checkform()">

That way your form still gets submitted (from the else part of your checkform()) and it shouldn't be reloading the page.

There are other, perhaps better, ways of handling it but this works in the mean time.

From Apple Docs

You can use subscript syntax to retrieve a value from the dictionary for a particular key. Because it is possible to request a key for which no value exists, a dictionary’s subscript returns an optional value of the dictionary’s value type. If the dictionary contains a value for the requested key, the subscript returns an optional value containing the existing value for that key. Otherwise, the subscript returns nil:

https://developer.apple.com/documentation/swift/dictionary

if let airportName = airports["DUB"] {
    print("The name of the airport is \(airportName).")
} else {
    print("That airport is not in the airports dictionary.")
}
// prints "The name of the airport is Dublin Airport."

You can use relative positioning to overlap your elements. However, the space they would normally occupy will still be reserved for the element:

<div style="background-color:#f00;width:200px;height:100px;">
    DEFAULT POSITIONED
</div>
<div style="background-color:#0f0;width:200px;height:100px;position:relative;top:-50px;left:50px;">
    RELATIVE POSITIONED
</div>
<div style="background-color:#00f;width:200px;height:100px;">
    DEFAULT POSITIONED
</div>

In the example above, there will be a block of white space between the two 'DEFAULT POSITIONED' elements. This is caused, because the 'RELATIVE POSITIONED' element still has it's space reserved.

If you use absolute positioning, your elements will not have any space reserved, so your element will actually overlap, without breaking your document:

<div style="background-color:#f00;width:200px;height:100px;">
    DEFAULT POSITIONED
</div>
<div style="background-color:#0f0;width:200px;height:100px;position:absolute;top:50px;left:50px;">
    ABSOLUTE POSITIONED
</div>
<div style="background-color:#00f;width:200px;height:100px;">
    DEFAULT POSITIONED
</div>

Finally, you can control which elements are on top of the others by using z-index:

<div style="z-index:10;background-color:#f00;width:200px;height:100px;">
    DEFAULT POSITIONED
</div>
<div style="z-index:5;background-color:#0f0;width:200px;height:100px;position:absolute;top:50px;left:50px;">
    ABSOLUTE POSITIONED
</div>
<div style="z-index:0;background-color:#00f;width:200px;height:100px;">
    DEFAULT POSITIONED
</div>

On ipython or jupyter notebook, you can use all the above mentioned ways, but i go with

I avoid using

One of the error could be that the file is not read as 'archive' format. check out ZipArchive not opening file - Error Code: 19. Open the downloaded file in text editor, if you have any html tags or debug statements at the starting, clear the buffer before reading the file.

what about simply constructing your frame from a standard list ?

frame = bytes([0xA2,0x01,0x02,0x03,0x04])

the bytes() constructor can build a byte frame from an iterable containing int values. an iterable is anything which implements the iterator protocol: an list, an iterator, an iterable object like what is returned by range()...

I've always used a method like

public static final byte[] fromHexString(final String s) {
    String[] v = s.split(" ");
    byte[] arr = new byte[v.length];
    int i = 0;
    for(String val: v) {
        arr[i++] =  Integer.decode("0x" + val).byteValue();

    }
    return arr;
}

this method splits on space delimited hex values but it wouldn't be hard to make it split the string on any other criteria such as into groupings of two characters.

I received a IllegalMonitorStateException while trying to wake up a thread in / from a different class / thread. In java 8 you can use the lock features of the new Concurrency API instead of synchronized functions.

I was already storing objects for asynchronous websocket transactions in a WeakHashMap. The solution in my case was to also store a lock object in a ConcurrentHashMap for synchronous replies. Note the condition.await (not .wait).

The content property states:

Authors may include newlines in the generated content by writing the "\A" escape sequence in one of the strings after the 'content' property. This inserted line break is still subject to the 'white-space' property. See "Strings" and "Characters and case" for more information on the "\A" escape sequence.

So you can use:

#headerAgentInfoDetailsPhone:after {
  content:"Office: XXXXX \A Mobile: YYYYY ";
  white-space: pre; /* or pre-wrap */
}

http://jsfiddle.net/XkNxs/

When escaping arbitrary strings, however, it's advisable to use \00000a instead of \A, because any number or [a-f] character followed by the new line may give unpredictable results:

function addTextToStyle(id, text) {
  return `#${id}::after { content: "${text.replace(/"/g, '\\"').replace(/\n/g, '\\00000a')} }"`;
}

You could use the .NET library to do the same thing which i believe is more straightforward.

        OleDbConnection objConn = null;
        System.Data.DataTable dt = null;
        //Create connection object by using the preceding connection string.
        objConn = new OleDbConnection(connString);
        objConn.Open();
        //Get the data table containg the schema guid.
        dt = objConn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
        string sql = string.Format("select * from [{0}$]", sheetName);
        var adapter = new System.Data.OleDb.OleDbDataAdapter(sql, ConnectionString);
        var ds = new System.Data.DataSet();
        string tableName = sheetName;
        adapter.Fill(ds, tableName);
        System.Data.DataTable data = ds.Tables[tableName];

After you have your data in the datatable you can access them as you would normally do with a DataTable class.

Port 465: IANA has reassigned a new service to this port, and it should no longer be used for SMTP communications.

However, because it was once recognized by IANA as valid, there may be legacy systems that are only capable of using this connection method. Typically, you will use this port only if your application demands it. A quick Google search, and you'll find many consumer ISP articles that suggest port 465 as the recommended setup. Hopefully this ends soon! It is not RFC compliant.

Port 587: This is the default mail submission port. When a mail client or server is submitting an email to be routed by a proper mail server, it should always use this port.

Everyone should consider using this port as default, unless you're explicitly blocked by your upstream network or hosting provider. This port, coupled with TLS encryption, will ensure that email is submitted securely and following the guidelines set out by the IETF.

Port 25: This port continues to be used primarily for SMTP relaying. SMTP relaying is the transmittal of email from email server to email server.

In most cases, modern SMTP clients (Outlook, Mail, Thunderbird, etc) shouldn't use this port. It is traditionally blocked, by residential ISPs and Cloud Hosting Providers, to curb the amount of spam that is relayed from compromised computers or servers. Unless you're specifically managing a mail server, you should have no traffic traversing this port on your computer or server.

1. first you can do with this style:

   mda="/usr/mda"
   if [ ! -L "${mda}" ]; then
     echo "=> File doesn't exist"
   fi
   

2. if you want to do it in more advanced style you can write it like below:

   #!/bin/bash
   mda="$1"
   if [ -e "$1" ]; then
       if [ ! -L "$1" ]
       then
           echo "you entry is not symlink"
       else
           echo "your entry is symlink"
       fi
   else
     echo "=> File doesn't exist"
   fi
   

the result of above is like:

root@linux:~# ./sym.sh /etc/passwd
you entry is not symlink
root@linux:~# ./sym.sh /usr/mda 
your entry is symlink
root@linux:~# ./sym.sh 
=> File doesn't exist

You can probably add two foreign key constraints (honestly: I've never tried it), but it'd then insist the parent row exist in both tables.

Instead you probably want to create a supertype for your two employee subtypes, and then point the foreign key there instead. (Assuming you have a good reason to split the two types of employees, of course).

                 employee       
employees_ce     ————————       employees_sn
————————————     type           ————————————
empid —————————> empid <——————— empid
name               /|\          name
                    |  
                    |  
      deductions    |  
      ——————————    |  
      empid ————————+  
      name

type in the employee table would be ce or sn.

import numpy as np

a = [1,2,3]    
b = np.array(a).reshape((1,3))    
np.savetxt('a.txt',b,fmt='%d')

I think this is a suboptimal solution, but you could do

String.format("%16s", Integer.toBinaryString(1)).replace(' ', '0')

A slight variation on andrew.fox answer, as the string to decode might not be a correct base64 encoded string:

using System;

namespace Service.Support
{
    public static class Base64
    {
        public static string ToBase64(this System.Text.Encoding encoding, string text)
        {
            if (text == null)
            {
                return null;
            }

            byte[] textAsBytes = encoding.GetBytes(text);
            return Convert.ToBase64String(textAsBytes);
        }

        public static bool TryParseBase64(this System.Text.Encoding encoding, string encodedText, out string decodedText)
        {
            if (encodedText == null)
            {
                decodedText = null;
                return false;
            }

            try
            {
                byte[] textAsBytes = Convert.FromBase64String(encodedText);
                decodedText = encoding.GetString(textAsBytes);
                return true;
            }
            catch (Exception)
            {
                decodedText = null;
                return false;   
            }
        }
    }
}

I had the same issue because my file was called email.py. I renamed the file and the issue disappeared.

Here's an easy solution and it's great for encoding accented characters too!

String in = "Hi Lârry & Môe!";

StringBuilder out = new StringBuilder();
for(int i = 0; i < in.length(); i++) {
    char c = in.charAt(i);
    if(c < 31 || c > 126 || "<>\"'\\&".indexOf(c) >= 0) {
        out.append("&#" + (int) c + ";");
    } else {
        out.append(c);
    }
}

System.out.printf("%s%n", out);

Outputs

Hi Lârry & Môe!

Delete android/app/build folder and run react-native run-android

SELECT DISTINCT groups.id, 
       (SELECT COUNT(*) FROM group_members
        WHERE member_id = groups.id) AS memberCount
FROM groups

Terminate the query with \G in place of ;. For example:

SELECT * FROM sometable\G

This query displays the rows vertically, like this:

*************************** 1. row ***************************
                 Host: localhost
                   Db: mydatabase1
                 User: myuser1
          Select_priv: Y
          Insert_priv: Y
          Update_priv: Y
          ...
*************************** 2. row ***************************
                 Host: localhost
                   Db: mydatabase2
                 User: myuser2
          Select_priv: Y
          Insert_priv: Y
          Update_priv: Y

Flex does this by default.

<div id="flex">
 <div id="response">

FWIW, I had what I think is a related problem and came up with a workaround: I wrote a Chrome Extension that did an document.execCommand('paste') into a textarea with focus on window unload in order to populate the element with the system clipboard contents. This worked 100% of the time manually, but the execCommand returned false almost all the time when run under Selenium.

I added a driver.refresh() after the initial driver.get( myChromeExtensionURL ), and now it works 100% of the time. This was with Selenium driver version 2.16.333243 and Chrome version 43 on Mac OS 10.9.

When I was researching the problem, I didn't see any mentions of this workaround, so I thought I'd document my discovery for those following in my Selenium/focus/execCommand('paste') footsteps.

Now, 2017, you can do it easier with the new MSTest V2 Framework:

Assert.ThrowsException<Exception>(() => myClass.MyMethodWithError());

//async version
await Assert.ThrowsExceptionAsync<SomeException>(
  () => myObject.SomeMethodAsync()
);

You won't be able to do it in a single replacement; you'll have to perform a few steps. Here's how I'd do it:

1. Find (in regular expression mode):

   (.+)
   

   Replace with:

   "\1"
   

   This adds the quotes:

   "AliceBlue"
   "AntiqueWhite"
   "Aqua"
   "Aquamarine"
   "Azure"
   "Beige"
   "Bisque"
   "Black"
   "BlanchedAlmond"
   

2. Find (in extended mode):

   \r\n
   

   Replace with (with a space after the comma, not shown):

   , 
   

   This converts the lines into a comma-separated list:

   "AliceBlue", "AntiqueWhite", "Aqua", "Aquamarine", "Azure", "Beige", "Bisque", "Black", "BlanchedAlmond"
   

3. Add the var myArray = assignment and braces manually:

   var myArray = ["AliceBlue", "AntiqueWhite", "Aqua", "Aquamarine", "Azure", "Beige", "Bisque", "Black", "BlanchedAlmond"];
   

You are right, the documentation lacks of those methods. However when I dug into rxjs repository, I found nice comments about tap (too long to paste here) and pipe operators:

  /**
   * Used to stitch together functional operators into a chain.
   * @method pipe
   * @return {Observable} the Observable result of all of the operators having
   * been called in the order they were passed in.
   *
   * @example
   *
   * import { map, filter, scan } from 'rxjs/operators';
   *
   * Rx.Observable.interval(1000)
   *   .pipe(
   *     filter(x => x % 2 === 0),
   *     map(x => x + x),
   *     scan((acc, x) => acc + x)
   *   )
   *   .subscribe(x => console.log(x))
   */

In brief:

Pipe: Used to stitch together functional operators into a chain. Before we could just do observable.filter().map().scan(), but since every RxJS operator is a standalone function rather than an Observable's method, we need pipe() to make a chain of those operators (see example above).

Tap: Can perform side effects with observed data but does not modify the stream in any way. Formerly called do(). You can think of it as if observable was an array over time, then tap() would be an equivalent to Array.forEach().

So far based on my research JasperSoft has turned out promising open source reporting tool… Matter of fact I am currently working on a huge project wherein I have started converting and building reports using JasperReports/iReports…

Every reporting tool has its own learning curve. The support group from and for Jasper and the quality of response that I have gotten so far is good.

Again at the end of the day it all comes down to what your business / organization needs.

Index the list then the dict.

print L[1]['d']

Well it depends on how you want to call this code.

Are you calling it from a button click on a form, if so then on the properties for the button on form, go to the Event tab, then On Click item, select [Event Procedure]. This will open the VBA code window for that button. You would then call your Module.Routine and then this would trigger when you click the button.

Similar to this:

Private Sub Command1426_Click()
    mdl_ExportMorning.ExportMorning
End Sub

This button click event calls the Module mdl_ExportMorning and the Public Sub ExportMorning.

Seems you haven't installed the Curl on your server.
Check the PHP version of your server and run the following command to install the curl.

sudo apt-get install php7.2-curl

Then restart the apache service by using the following command.

sudo service apache2 restart

Replace 7.2 with your PHP version.

Unique pointers are guaranteed to destroy the object they manage when they go out of scope. http://en.cppreference.com/w/cpp/memory/unique_ptr

In this case:

unique_ptr<double> uptr2 (pd);

pd will be destroyed when uptr2 goes out of scope. This facilitates memory management by automatic deletion.

The case of unique_ptr<int> uptr (new int(3)); is not different, except that the raw pointer is not assigned to any variable here.

TL;DR

1. Use 172.17.0.0/16 as IP address range, not 172.17.0.0/32.
2. Don't use localhost to connect to the PostgreSQL database on your host, but the host's IP instead. To keep the container portable, start the container with the --add-host=database:<host-ip> flag and use database as hostname for connecting to PostgreSQL.
3. Make sure PostgreSQL is configured to listen for connections on all IP addresses, not just on localhost. Look for the setting listen_addresses in PostgreSQL's configuration file, typically found in /etc/postgresql/9.3/main/postgresql.conf (credits to @DazmoNorton).

Long version

172.17.0.0/32 is not a range of IP addresses, but a single address (namly 172.17.0.0). No Docker container will ever get that address assigned, because it's the network address of the Docker bridge (docker0) interface.

When Docker starts, it will create a new bridge network interface, that you can easily see when calling ip a:

$ ip a
...
3: docker0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN 
    link/ether 56:84:7a:fe:97:99 brd ff:ff:ff:ff:ff:ff
    inet 172.17.42.1/16 scope global docker0
       valid_lft forever preferred_lft forever

As you can see, in my case, the docker0 interface has the IP address 172.17.42.1 with a netmask of /16 (or 255.255.0.0). This means that the network address is 172.17.0.0/16.

The IP address is randomly assigned, but without any additional configuration, it will always be in the 172.17.0.0/16 network. For each Docker container, a random address from that range will be assigned.

This means, if you want to grant access from all possible containers to your database, use 172.17.0.0/16.

• window.open will open a new browser with the specified URL.

• window.location.href will open the URL in the window in which the code is called.

Note also that window.open() is a function on the window object itself whereas window.location is an object that exposes a variety of other methods and properties.

There are also new kids on the block!

• Besides the already mentioned deprecated optparse. [DO NOT USE]
• argparse was also mentioned, which is a solution for people not willing to include external libs.
• docopt is an external lib worth looking at, which uses a documentation string as the parser for your input.
• click is also external lib and uses decorators for defining arguments. (My source recommends: Why Click)
• python-inquirer For selection focused tools and based on Inquirer.js (repo)

If you need a more in-depth comparison please read this and you may end up using docopt or click. Thanks to Kyle Purdon!

.str.get

This is the simplest to specify string methods

# Setup
df = pd.DataFrame({'A': ['xyz', 'abc', 'foobar'], 'B': [123, 456, 789]})
df

        A    B
0     xyz  123
1     abc  456
2  foobar  789

df.dtypes

A    object
B     int64
dtype: object

For string (read:object) type columns, use

df['C'] = df['A'].str[0]
# Similar to,
df['C'] = df['A'].str.get(0)

.str handles NaNs by returning NaN as the output.

For non-numeric columns, an .astype conversion is required beforehand, as shown in @Ed Chum's answer.

# Note that this won't work well if the data has NaNs. 
# It'll return lowercase "n"
df['D'] = df['B'].astype(str).str[0]

df
        A    B  C  D
0     xyz  123  x  1
1     abc  456  a  4
2  foobar  789  f  7

List Comprehension and Indexing

There is enough evidence to suggest a simple list comprehension will work well here and probably be faster.

# For string columns
df['C'] = [x[0] for x in df['A']]

# For numeric columns
df['D'] = [str(x)[0] for x in df['B']]

df
        A    B  C  D
0     xyz  123  x  1
1     abc  456  a  4
2  foobar  789  f  7

If your data has NaNs, then you will need to handle this appropriately with an if/else in the list comprehension,

df2 = pd.DataFrame({'A': ['xyz', np.nan, 'foobar'], 'B': [123, 456, np.nan]})
df2

        A      B
0     xyz  123.0
1     NaN  456.0
2  foobar    NaN

# For string columns
df2['C'] = [x[0] if isinstance(x, str) else np.nan for x in df2['A']]

# For numeric columns
df2['D'] = [str(x)[0] if pd.notna(x) else np.nan for x in df2['B']]

        A      B    C    D
0     xyz  123.0    x    1
1     NaN  456.0  NaN    4
2  foobar    NaN    f  NaN

Let's do some timeit tests on some larger data.

df_ = df.copy()
df = pd.concat([df_] * 5000, ignore_index=True) 

%timeit df.assign(C=df['A'].str[0])
%timeit df.assign(D=df['B'].astype(str).str[0])

%timeit df.assign(C=[x[0] for x in df['A']])
%timeit df.assign(D=[str(x)[0] for x in df['B']])

12 ms ± 253 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
27.1 ms ± 1.38 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)

3.77 ms ± 110 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
7.84 ms ± 145 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

List comprehensions are 4x faster.

if you don't want to use parser :

int a;
String s;
Scanner scan = new Scanner(System.in);

System.out.println("enter a no");
a = scan.nextInt();
System.out.println("no is =" + a);
scan.nextLine(); // This line you have to add (It consumes the \n character)
System.out.println("enter a string");
s = scan.nextLine();
System.out.println("string is=" + s);

What happens in reality in case you pass string as a first parameter of function

setTimeout('string',number)

is value of first param got evaluated when it is time to run (after numberof miliseconds passed). Basically it is equal to

setTimeout(eval('string'), number)

This is

an alternative syntax that allows you to include a string instead of a function, which is compiled and executed when the timer expires. This syntax is not recommended for the same reasons that make using eval() a security risk.

So samples which you refer are not good samples, and may be given in different context or just simple typo.

If you invoke like this setTimeout(something, number), first parameter is not string, but pointer to a something called something. And again if something is string - then it will be evaluated. But if it is function, then function will be executed. jsbin sample

Here is the best way to set your root password : Source Link Step 3 is working perfectly for me.

Commands for You

1. sudo mysql
2. SELECT user,authentication_string,plugin,host FROM mysql.user;
3. ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
4. FLUSH PRIVILEGES;
5. SELECT user,authentication_string,plugin,host FROM mysql.user;
6. exit

Now you can use the Password for the root user is 'password' :

1. mysql -u root -p
2. CREATE USER 'sammy'@'localhost' IDENTIFIED BY 'password';
3. GRANT ALL PRIVILEGES ON . TO 'sammy'@'localhost' WITH GRANT OPTION;
4. FLUSH PRIVILEGES;
5. exit

Test your MySQL Service and Version:

systemctl status mysql.service
sudo mysqladmin -p -u root version

If you are having a small script that you need to run (I simply needed to copy a file), I found it much easier to call the commands on the PHP script by calling

exec("sudo cp /tmp/testfile1 /var/www/html/testfile2");

and enabling such transaction by editing (or rather adding) a permitting line to the sudoers by first calling sudo visudo and adding the following line to the very end of it

www-data ALL=(ALL) NOPASSWD:/bin/cp /tmp/testfile1 /var/www/html/testfile2

All I wanted to do was to copy a file and I have been having problems with doing so because of the root password problem, and as you mentioned I did NOT want to expose the system to have no password for all root transactions.

If you still get

TCPDF ERROR: Unable to create output file: myfile.pdf

you can avoid TCPDF's file saving logic by putting PDF data to a variable and saving this string to a file:

$pdf_string = $pdf->Output('pseudo.pdf', 'S');
file_put_contents('./mydir/myfile.pdf', $pdf_string);

This is from MSDN sample:

(*.bmp, *.jpg)|*.bmp;*.jpg

So for your case

openFileDialog1.Filter = "JPG (*.jpg,*.jpeg)|*.jpg;*.jpeg|TIFF (*.tif,*.tiff)|*.tif;*.tiff"

I think we can improve the best answer a little bit, I'm using:

len = sum(1 for _ in reader)

Moreover, we shouldnt forget pythonic code not always have the best performance in the project. In example: If we can do more operations at the same time in the same data set Its better to do all in the same bucle instead make two or more pythonic bucles.

You might also want to look at the subprocess module, which was built to replace the whole family of Python popen-type calls.

import subprocess
output = subprocess.check_output("cat /etc/services", shell=True)

The advantage it has is that there is a ton of flexibility with how you invoke commands, where the standard in/out/error streams are connected, etc.

I have solved the same issue by giving the read permision from github account.

1. Go to github account go the user write permission.
2. When we clone the code we need read permission.
3. When we need to push the code we use write permission so you need to give write permission.

Put variables that will be changed by your interaction at extraData

You can be creative.

For example if you are dealing with a changing list with checkboxes on them.

<FlatList
      data={this.state.data.items}
      extraData={this.state.data.items.length * (this.state.data.done.length + 1) }
      renderItem={({item}) => <View>  

I would like to refer a previous question, Because I have faced same problem and solved by this solution. First of all a constraint is always built with a Hash value in it's name. So problem is this HASH is varies in different Machine or Database. For example DF__Companies__IsGlo__6AB17FE4 here 6AB17FE4 is the hash value(8 bit). So I am referring a single script which will be fruitful to all

DECLARE @Command NVARCHAR(MAX)
     declare @table_name nvarchar(256)
     declare @col_name nvarchar(256)
     set @table_name = N'ProcedureAlerts'
     set @col_name = N'EmailSent'

     select @Command ='Alter Table dbo.ProcedureAlerts Drop Constraint [' + ( select d.name
     from 
         sys.tables t
         join sys.default_constraints d on d.parent_object_id = t.object_id
         join sys.columns c on c.object_id = t.object_id
                               and c.column_id = d.parent_column_id
     where 
         t.name = @table_name
         and c.name = @col_name) + ']'

    --print @Command
    exec sp_executesql @Command

It will drop your default constraint. However if you want to create it again you can simply try this

ALTER TABLE [dbo].[ProcedureAlerts] ADD DEFAULT((0)) FOR [EmailSent]

Finally, just simply run a DROP command to drop the column.

Use the Date get methods.

http://www.tizag.com/javascriptT/javascriptdate.php

http://www.htmlgoodies.com/beyond/javascript/article.php/3470841

var dateobj= new Date() ;
var month = dateobj.getMonth() + 1;
var day = dateobj.getDate() ;
var year = dateobj.getFullYear();

I suggest to add the '+' operator as follows:

list = list + ['foo']

Hope it helps!

I was able to customize the hrTag by editing the inline styling as such:

<div class="row"> <!-- You can also position the row if need be. -->
<div class="col-md-12 col-lg-12"><!-- set width of column I wanted mine to stretch most of the screen-->
<hr style="min-width:85%; background-color:#a1a1a1 !important; height:1px;"/>
</div>
 </div>

The hrTag is now thicker and more visible; it's also a darker gray color. The bootstrap code is actually very flexible. As the snippet demonstrates above, you can use inline styling or your own custom code. Hope this helps someone.

If you don't see the formatting option, you can do Tools->Import and Export settings to import the missing one.

foreach($shipmentarr as $index=>$val){    
    $additionalService = array();

    foreach($additionalService[$index] as $key => $value) {

        array_push($additionalService,$value);

    }
}

To write it with a while loop you can do:

ls -f /var | while read -r file; do cmd $file; done

The primary disadvantage of this is that cmd is run in a subshell, which causes some difficulty if you are trying to set variables. The main advantages are that the shell does not need to load all of the filenames into memory, and there is no globbing. When you have a lot of files in the directory, those advantages are important (that's why I use -f on ls; in a large directory ls itself can take several tens of seconds to run and -f speeds that up appreciably. In such cases 'for file in /var/*' will likely fail with a glob error.)

The char is a fixed-length character data type, the varchar is a variable-length character data type.

Because char is a fixed-length data type, the storage size of the char value is equal to the maximum size for this column. Because varchar is a variable-length data type, the storage size of the varchar value is the actual length of the data entered, not the maximum size for this column.

You can use char when the data entries in a column are expected to be the same size. You can use varchar when the data entries in a column are expected to vary considerably in size.

All you have to do is define your result as a string array, like the following:

const result : string[] = [];

Without defining the array type, it by default will be never. So when you tried to add a string to it, it was a type mismatch, and so it threw the error you saw.

Pure JavaScript version:

document.querySelector('input[name="myradio"][value="5"]').checked = true;

You can create an array containing the numbers 0 to 5 and shuffle those. Then use the result as a mapping of "oldIndex -> newIndex" and apply this mapping to both your original arrays.

Not wanting to edit my git config file I followed the info in @mipadi's post and used:

$ git pull origin master

A global variable would be best expressed in an external JavaScript file:

var system_status;

Make sure that this has not been used anywhere else. Then to access the variable on your page, just reference it as such. Say, for example, you wanted to fill in the results on a textbox,

document.getElementById("textbox1").value = system_status;

To ensure that the object exists, use the document ready feature of jQuery.

Example:

$(function() {
    $("#textbox1")[0].value = system_status;
});

trick:

    int time_len = 0, n;
    struct tm *tm_info;
    struct timeval tv;

    gettimeofday(&tv, NULL);
    tm_info = localtime(&tv.tv_sec);
    time_len+=strftime(log_buff, sizeof log_buff, "%y%m%d %H:%M:%S", tm_info);
    time_len+=snprintf(log_buff+time_len,sizeof log_buff-time_len,".%03ld ",tv.tv_usec/1000);

You can have an iframe inside the modal markup and give the src attribute of it as the link to your pdf. On click of the link you can show this modal markup.

Try this:

SET TERMOUT OFF; 
spool M:\Documents\test;
select * from employees;
/
spool off;

window.location = appurl;// fb://method/call..
!window.document.webkitHidden && setTimeout(function () {
    setTimeout(function () {
    window.location = weburl; // http://itunes.apple.com/..
    }, 100);
}, 600);

document.webkitHidden is to detect if your app is already invoked and current safari tab to going to the background, this code is from www.baidu.com

How about this: location.href.slice(0, - ((location.search + location.hash).length))

Solution 3

This is for using a single directory for multiple projects. I use this technique for some closely related projects where I often need to pull changes from one project into another. It's similar to the orphaned branches idea but the branches don't need to be orphaned. Simply start all the projects from the same empty directory state.

Start all projects from one committed empty directory

Don't expect wonders from this solution. As I see it, you are always going to have annoyances with untracked files. Git doesn't really have a clue what to do with them and so if there are intermediate files generated by a compiler and ignored by your .gitignore file, it is likely that they will be left hanging some of the time if you try rapidly swapping between - for example - your software project and a PH.D thesis project.

However here is the plan. Start as you ought to start any git projects, by committing the empty repository, and then start all your projects from the same empty directory state. That way you are certain that the two lots of files are fairly independent. Also, give your branches a proper name and don't lazily just use "master". Your projects need to be separate so give them appropriate names.

Git commits (and hence tags and branches) basically store the state of a directory and its subdirectories and Git has no idea whether these are parts of the same or different projects so really there is no problem for git storing different projects in the same repository. The problem is then for you clearing up the untracked files from one project when using another, or separating the projects later.

Create an empty repository

cd some_empty_directory
git init
touch .gitignore
git add .gitignore
git commit -m empty
git tag EMPTY

Start your projects from empty.

Work on one project.

git branch software EMPTY
git checkout software
echo "array board[8,8] of piece" > chess.prog

git add chess.prog 
git commit -m "chess program"

Start another project

whenever you like.

git branch thesis EMPTY
git checkout thesis
echo "the meaning of meaning" > philosophy_doctorate.txt
git add philosophy_doctorate.txt 
git commit -m "Ph.D"

Switch back and forth

Go back and forwards between projects whenever you like. This example goes back to the chess software project.

git checkout software
echo "while not end_of_game do make_move()" >> chess.prog
git add chess.prog 
git commit -m "improved chess program"

Untracked files are annoying

You will however be annoyed by untracked files when swapping between projects/branches.

touch untracked_software_file.prog
git checkout thesis 
ls
    philosophy_doctorate.txt  untracked_software_file.prog

It's not an insurmountable problem

Sort of by definition, git doesn't really know what to do with untracked files and it's up to you to deal with them. You can stop untracked files from being carried around from one branch to another as follows.

git checkout EMPTY 
ls
    untracked_software_file.prog
rm -r *
    (directory is now really empty, apart from the repository stuff!)
git checkout thesis
ls
    philosophy_doctorate.txt

By ensuring that the directory was empty before checking out our new project we made sure there were no hanging untracked files from another project.

A refinement

$ GIT_AUTHOR_DATE='2001-01-01:T01:01:01' GIT_COMMITTER_DATE='2001-01-01T01:01:01' git commit -m empty

If the same dates are specified whenever committing an empty repository, then independently created empty repository commits can have the same SHA1 code. This allows two repositories to be created independently and then merged together into a single tree with a common root in one repository later.

Example

# Create thesis repository. 
# Merge existing chess repository branch into it

mkdir single_repo_for_thesis_and_chess
cd single_repo_for_thesis_and_chess
git init
touch .gitignore
git add .gitignore
GIT_AUTHOR_DATE='2001-01-01:T01:01:01' GIT_COMMITTER_DATE='2001-01-01:T01:01:01' git commit -m empty
git tag EMPTY
echo "the meaning of meaning" > thesis.txt
git add thesis.txt
git commit -m "Wrote my PH.D"
git branch -m master thesis

# It's as simple as this ...
git remote add chess ../chessrepository/.git
git fetch chess chess:chess

Result

Use subdirectories per project?

It may also help if you keep your projects in subdirectories where possible, e.g. instead of having files

chess.prog
philosophy_doctorate.txt 

have

chess/chess.prog
thesis/philosophy_doctorate.txt 

In this case your untracked software file will be chess/untracked_software_file.prog. When working in the thesis directory you should not be disturbed by untracked chess program files, and you may find occasions when you can work happily without deleting untracked files from other projects.

Also, if you want to remove untracked files from other projects, it will be quicker (and less prone to error) to dump an unwanted directory than to remove unwanted files by selecting each of them.

Branch names can include '/' characters

So you might want to name your branches something like

project1/master
project1/featureABC
project2/master
project2/featureXYZ

strip only strips characters from the very front and back of the string.

To delete a list of characters, you could use the string's translate method:

import string
name = "Barack (of Washington)"
table = string.maketrans( '', '', )
print name.translate(table,"(){}<>")
# Barack of Washington

Simple copy & paste example with subqueries, Note, that both queries should return 1 row:

select
(select sum(items_1) from items_table_1 where ...)
-
(select count(items_2) from items_table_1 where ...) 

as difference

Swift version:

textLabel.adjustsFontSizeToFitWidth = true
textLabel.minimumScaleFactor = 0.5

Swift is worry that your case statement is not covering all cases, to fix it you need to create a default case:

do {
    let sandwich = try makeMeSandwich(kitchen)
    print("i eat it \(sandwich)")
} catch SandwichError.NotMe {
    print("Not me error")
} catch SandwichError.DoItYourself {
    print("do it error")
} catch Default {
    print("Another Error")
}

I am going to Necro this topic.

Starting around ms-access-2016, you can execute Data Definition Queries (DDQ) through Macro's

Data Definition Query

ALTER TABLE <Table> ALTER COLUMN <ID_Field> COUNTER(1,1);

1. Save the DDQ, with your values
2. Create a Macro with the appropriate logic either before this or after.
3. To execute this DDQ:
   • Add an Open Query action
   • Define the name of the DDQ in the Query Name field; View and Data Mode settings are not relevant and can leave the default values

WARNINGS!!!!

1. This will reset the AutoNumber Counter to 1
2. Any Referential Integrity will be summarily destroyed

Advice

• Use this for Staging tables
  • these are tables that are never intended to persist the data they temporarily contain.
  • The data contained is only there until additional cleaning actions have been performed and stored in the appropriate table(s).
  • Once cleaning operations have been performed and the data is no longer needed, these tables are summarily purged of any data contained.
• Import Tables
  • These are very similar to Staging Tables but tend to only have two columns: ID and RowValue
  • Since these are typically used to import RAW data from a general file format (TXT, RTF, CSV, XML, etc.), the data contained does not persist past the processing lifecycle

android only use linux kernel, that means the GNU tool chain like gcc as are not implemented in android, so if you want run a linux app in android, you need recompile it with google's tool chain( NDK ).

Html.Raw() returns IHtmlString, not the ordinary string. So, you cannot write them in opposite sides of : operator. Remove that .ToString() calling

@{int count = 0;}
@foreach (var item in Model.Resources)
{
    @(count <= 3 ? Html.Raw("<div class=\"resource-row\">"): Html.Raw("")) 
    // some code
    @(count <= 3 ? Html.Raw("</div>") : Html.Raw("")) 
    @(count++)

}

By the way, returning IHtmlString is the way MVC recognizes html content and does not encode it. Even if it hasn't caused compiler errors, calling ToString() would destroy meaning of Html.Raw()

Although this doesn't answer the question (requiring a common script), I though it might be useful for others to know that HTML5 introduces the 'autofocus' attribute:

<form>
  <input type="text" name="username" autofocus>
  <input type="password" name="password">
  <input type="submit" value="Login">
</form>

Dive in to HTML5 has more information.

use this filter:

(dns.flags.response == 0) and (ip.src == 159.25.78.7)

what this query does is it only gives dns queries originated from your ip

malloc and free are implementation dependent. A typical implementation involves partitioning available memory into a "free list" - a linked list of available memory blocks. Many implementations artificially divide it into small vs large objects. Free blocks start with information about how big the memory block is and where the next one is, etc.

When you malloc, a block is pulled from the free list. When you free, the block is put back in the free list. Chances are, when you overwrite the end of your pointer, you are writing on the header of a block in the free list. When you free your memory, free() tries to look at the next block and probably ends up hitting a pointer that causes a bus error.

I am trying to understand what Python's descriptors are and what they can be useful for.

Descriptors are class attributes (like properties or methods) with any of the following special methods:

• __get__ (non-data descriptor method, for example on a method/function)
• __set__ (data descriptor method, for example on a property instance)
• __delete__ (data descriptor method)

These descriptor objects can be used as attributes on other object class definitions. (That is, they live in the __dict__ of the class object.)

Descriptor objects can be used to programmatically manage the results of a dotted lookup (e.g. foo.descriptor) in a normal expression, an assignment, and even a deletion.

Functions/methods, bound methods, property, classmethod, and staticmethod all use these special methods to control how they are accessed via the dotted lookup.

A data descriptor, like property, can allow for lazy evaluation of attributes based on a simpler state of the object, allowing instances to use less memory than if you precomputed each possible attribute.

Another data descriptor, a member_descriptor, created by __slots__, allow memory savings by allowing the class to store data in a mutable tuple-like datastructure instead of the more flexible but space-consuming __dict__.

Non-data descriptors, usually instance, class, and static methods, get their implicit first arguments (usually named cls and self, respectively) from their non-data descriptor method, __get__.

Most users of Python need to learn only the simple usage, and have no need to learn or understand the implementation of descriptors further.

In Depth: What Are Descriptors?

A descriptor is an object with any of the following methods (__get__, __set__, or __delete__), intended to be used via dotted-lookup as if it were a typical attribute of an instance. For an owner-object, obj_instance, with a descriptor object:

• obj_instance.descriptor invokes
  descriptor.__get__(self, obj_instance, owner_class) returning a value
  This is how all methods and the get on a property work.

• obj_instance.descriptor = value invokes
  descriptor.__set__(self, obj_instance, value) returning None
  This is how the setter on a property works.

• del obj_instance.descriptor invokes
  descriptor.__delete__(self, obj_instance) returning None
  This is how the deleter on a property works.

obj_instance is the instance whose class contains the descriptor object's instance. self is the instance of the descriptor (probably just one for the class of the obj_instance)

To define this with code, an object is a descriptor if the set of its attributes intersects with any of the required attributes:

def has_descriptor_attrs(obj):
    return set(['__get__', '__set__', '__delete__']).intersection(dir(obj))

def is_descriptor(obj):
    """obj can be instance of descriptor or the descriptor class"""
    return bool(has_descriptor_attrs(obj))

A Data Descriptor has a __set__ and/or __delete__.
A Non-Data-Descriptor has neither __set__ nor __delete__.

def has_data_descriptor_attrs(obj):
    return set(['__set__', '__delete__']) & set(dir(obj))

def is_data_descriptor(obj):
    return bool(has_data_descriptor_attrs(obj))

Builtin Descriptor Object Examples:

• classmethod
• staticmethod
• property
• functions in general

Non-Data Descriptors

We can see that classmethod and staticmethod are Non-Data-Descriptors:

>>> is_descriptor(classmethod), is_data_descriptor(classmethod)
(True, False)
>>> is_descriptor(staticmethod), is_data_descriptor(staticmethod)
(True, False)

Both only have the __get__ method:

>>> has_descriptor_attrs(classmethod), has_descriptor_attrs(staticmethod)
(set(['__get__']), set(['__get__']))

Note that all functions are also Non-Data-Descriptors:

>>> def foo(): pass
... 
>>> is_descriptor(foo), is_data_descriptor(foo)
(True, False)

Data Descriptor, property

However, property is a Data-Descriptor:

>>> is_data_descriptor(property)
True
>>> has_descriptor_attrs(property)
set(['__set__', '__get__', '__delete__'])

Dotted Lookup Order

These are important distinctions, as they affect the lookup order for a dotted lookup.

obj_instance.attribute

1. First the above looks to see if the attribute is a Data-Descriptor on the class of the instance,
2. If not, it looks to see if the attribute is in the obj_instance's __dict__, then
3. it finally falls back to a Non-Data-Descriptor.

The consequence of this lookup order is that Non-Data-Descriptors like functions/methods can be overridden by instances.

Recap and Next Steps

We have learned that descriptors are objects with any of __get__, __set__, or __delete__. These descriptor objects can be used as attributes on other object class definitions. Now we will look at how they are used, using your code as an example.

Analysis of Code from the Question

Here's your code, followed by your questions and answers to each:

class Celsius(object):
    def __init__(self, value=0.0):
        self.value = float(value)
    def __get__(self, instance, owner):
        return self.value
    def __set__(self, instance, value):
        self.value = float(value)

class Temperature(object):
    celsius = Celsius()

1. Why do I need the descriptor class?

Your descriptor ensures you always have a float for this class attribute of Temperature, and that you can't use del to delete the attribute:

>>> t1 = Temperature()
>>> del t1.celsius
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: __delete__

Otherwise, your descriptors ignore the owner-class and instances of the owner, instead, storing state in the descriptor. You could just as easily share state across all instances with a simple class attribute (so long as you always set it as a float to the class and never delete it, or are comfortable with users of your code doing so):

class Temperature(object):
    celsius = 0.0

This gets you exactly the same behavior as your example (see response to question 3 below), but uses a Pythons builtin (property), and would be considered more idiomatic:

class Temperature(object):
    _celsius = 0.0
    @property
    def celsius(self):
        return type(self)._celsius
    @celsius.setter
    def celsius(self, value):
        type(self)._celsius = float(value)

2. What is instance and owner here? (in get). What is the purpose of these parameters?

instance is the instance of the owner that is calling the descriptor. The owner is the class in which the descriptor object is used to manage access to the data point. See the descriptions of the special methods that define descriptors next to the first paragraph of this answer for more descriptive variable names.

3. How would I call/use this example?

Here's a demonstration:

>>> t1 = Temperature()
>>> t1.celsius
0.0
>>> t1.celsius = 1
>>> 
>>> t1.celsius
1.0
>>> t2 = Temperature()
>>> t2.celsius
1.0

You can't delete the attribute:

>>> del t2.celsius
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: __delete__

And you can't assign a variable that can't be converted to a float:

>>> t1.celsius = '0x02'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 7, in __set__
ValueError: invalid literal for float(): 0x02

Otherwise, what you have here is a global state for all instances, that is managed by assigning to any instance.

The expected way that most experienced Python programmers would accomplish this outcome would be to use the property decorator, which makes use of the same descriptors under the hood, but brings the behavior into the implementation of the owner class (again, as defined above):

class Temperature(object):
    _celsius = 0.0
    @property
    def celsius(self):
        return type(self)._celsius
    @celsius.setter
    def celsius(self, value):
        type(self)._celsius = float(value)

Which has the exact same expected behavior of the original piece of code:

>>> t1 = Temperature()
>>> t2 = Temperature()
>>> t1.celsius
0.0
>>> t1.celsius = 1.0
>>> t2.celsius
1.0
>>> del t1.celsius
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: can't delete attribute
>>> t1.celsius = '0x02'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 8, in celsius
ValueError: invalid literal for float(): 0x02

Conclusion

We've covered the attributes that define descriptors, the difference between data- and non-data-descriptors, builtin objects that use them, and specific questions about use.

So again, how would you use the question's example? I hope you wouldn't. I hope you would start with my first suggestion (a simple class attribute) and move on to the second suggestion (the property decorator) if you feel it is necessary.

Use this easy method

  $a='Link1';
  $b='Link2';
  echo "<a href=\"pass.php?link=$a\">Link 1</a>";
  echo '<br/>';
  echo "<a href=\"pass.php?link=$b\">Link 2</a>";

Here is my version, adapted from others. I spent 30 minutes just now trying to remember how I came up with this, and @Jeremy 's answer seems to be the core inspiration. I didn't want to update Jeremy's answer, just in case I introduced bugs, so I am posting my version of it here.

I suggest pairing the full script with some inspiration taken from Kenneth Fisher's T-SQL Tuesday: What Permissions Does a Specific User Have?: This will allow you to answer compliance/audit questions bottom-up, as opposed to top-down.

EXECUTE AS LOGIN = '<loginname>'

SELECT token.name AS GroupNames
FROM sys.login_token token
JOIN sys.server_principals grp
    ON token.sid = grp.sid
WHERE token.[type] = 'WINDOWS GROUP'
  AND grp.[type] = 'G'

REVERT

To understand what this covers, consider Contoso\DB_AdventureWorks_Accounting Windows AD Group with member Contoso\John.Doe. John.Doe authenticates to AdventureWorks via server_principal Contoso\DB_AdventureWorks_Logins Windows AD Group. If someone asks you, "What permissions does John.Doe have?", you cannot answer that question with just the below script. You need to then iterate through each row returned by the below script and join it to the above script. (You may also need to normalize for stale name values via looking up the SID in your Active Directory provider.)

Here is the script, without incorporating such reverse look-up logic.

I think that var_export(), the forgotten brother of var_dump() has the best output - it's more compact:

echo "<pre>";
var_export($menue);
echo "</pre>";

By the way: it's not allway necessary to use <pre>. var_dump() and var_export() are already formatted when you take a look in the source code of your webpage.

http://sourceforge.net/projects/javacsv/

https://github.com/pupi1985/JavaCSV-Reloaded (fork of the previous library that will allow the generated output to have Windows line terminators \r\n when not running Windows)

CSV API for Java

Can you recommend a Java library for reading (and possibly writing) CSV files?

Java lib or app to convert CSV to XML file?

The only time I have experienced this was when the MVC framework was not installed on the server. Could that be the case?

A missing Pages section in Views\Web.config could also be at fault.

older versions xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

This changed again in Angular2 RC.5

I will update the example below but it's the last day before vacation.

This Plunker example demonstrates how to dynamically create components in RC.5

Update - use ViewContainerRef.createComponent()

Because DynamicComponentLoader is deprecated, the approach needs to be update again.

@Component({
  selector: 'dcl-wrapper',
  template: `<div #target></div>`
})
export class DclWrapper {
  @ViewChild('target', {read: ViewContainerRef}) target;
  @Input() type;
  cmpRef:ComponentRef;
  private isViewInitialized:boolean = false;

  constructor(private resolver: ComponentResolver) {}

  updateComponent() {
    if(!this.isViewInitialized) {
      return;
    }
    if(this.cmpRef) {
      this.cmpRef.destroy();
    }
   this.resolver.resolveComponent(this.type).then((factory:ComponentFactory<any>) => {
      this.cmpRef = this.target.createComponent(factory)
      // to access the created instance use
      // this.compRef.instance.someProperty = 'someValue';
      // this.compRef.instance.someOutput.subscribe(val => doSomething());
    });
  }

  ngOnChanges() {
    this.updateComponent();
  }

  ngAfterViewInit() {
    this.isViewInitialized = true;
    this.updateComponent();  
  }

  ngOnDestroy() {
    if(this.cmpRef) {
      this.cmpRef.destroy();
    }    
  }
}

Plunker example RC.4
Plunker example beta.17

Update - use loadNextToLocation

export class DclWrapper {
  @ViewChild('target', {read: ViewContainerRef}) target;
  @Input() type;
  cmpRef:ComponentRef;
  private isViewInitialized:boolean = false;

  constructor(private dcl:DynamicComponentLoader) {}

  updateComponent() {
    // should be executed every time `type` changes but not before `ngAfterViewInit()` was called 
    // to have `target` initialized
    if(!this.isViewInitialized) {
      return;
    }
    if(this.cmpRef) {
      this.cmpRef.destroy();
    }
    this.dcl.loadNextToLocation(this.type, this.target).then((cmpRef) => {
      this.cmpRef = cmpRef;
    });
  }

  ngOnChanges() {
    this.updateComponent();
  }

  ngAfterViewInit() {
    this.isViewInitialized = true;
    this.updateComponent();  
  }

  ngOnDestroy() {
    if(this.cmpRef) {
      this.cmpRef.destroy();
    }    
  }
}

original

Not entirely sure from your question what your requirements are but I think this should do what you want.

The Tabs component gets an array of types passed and it creates "tabs" for each item in the array.

@Component({
  selector: 'dcl-wrapper',
  template: `<div #target></div>`
})
export class DclWrapper {
  constructor(private elRef:ElementRef, private dcl:DynamicComponentLoader) {}
  @Input() type;

  ngOnChanges() {
    if(this.cmpRef) {
      this.cmpRef.dispose();
    }
    this.dcl.loadIntoLocation(this.type, this.elRef, 'target').then((cmpRef) => {
      this.cmpRef = cmpRef;
    });
  }
}

@Component({
  selector: 'c1',
  template: `<h2>c1</h2>`

})
export class C1 {
}

@Component({
  selector: 'c2',
  template: `<h2>c2</h2>`

})
export class C2 {
}

@Component({
  selector: 'c3',
  template: `<h2>c3</h2>`

})
export class C3 {
}

@Component({
  selector: 'my-tabs',
  directives: [DclWrapper],
  template: `
  <h2>Tabs</h2>
  <div *ngFor="let tab of tabs">
    <dcl-wrapper [type]="tab"></dcl-wrapper>
  </div>
`
})
export class Tabs {
  @Input() tabs;
}


@Component({
  selector: 'my-app',
  directives: [Tabs]
  template: `
  <h2>Hello {{name}}</h2>
  <my-tabs [tabs]="types"></my-tabs>
`
})
export class App {
  types = [C3, C1, C2, C3, C3, C1, C1];
}

Plunker example beta.15 (not based on your Plunker)

There is also a way to pass data along that can be passed to the dynamically created component like (someData would need to be passed like type)

    this.dcl.loadIntoLocation(this.type, this.elRef, 'target').then((cmpRef) => {
  cmpRef.instance.someProperty = someData;
  this.cmpRef = cmpRef;
});

There is also some support to use dependency injection with shared services.

For more details see https://angular.io/docs/ts/latest/cookbook/dynamic-component-loader.html

The open SPF wizard from the previous answer is no longer available, neither the one from Microsoft.

I'm not sure I understand your question, but if you want the image to fill the entire screen you can use a DecorationImage with a fit of BoxFit.cover.

class BaseLayout extends StatelessWidget{
  @override
  Widget build(BuildContext context){
    return Scaffold(
      body: Container(
        decoration: BoxDecoration(
          image: DecorationImage(
            image: AssetImage("assets/images/bulb.jpg"),
            fit: BoxFit.cover,
          ),
        ),
        child: null /* add child content here */,
      ),
    );
  }
}

For your second question, here is a link to the documentation on how to embed resolution-dependent asset images into your app.

Check this.

 .header{width:100%;
    }

    .header img{ width: 20%; //or whatever width you like to have

    }

    .header h1{

    display:inline; //It will take rest of space which left by logo.
}

When this method executes, it retrieves the content of location.href, but then jQuery parses the returned document to find the element with divId. This element, along with its contents, is inserted into the element with an ID (divId) of result, and the rest of the retrieved document is discarded.

$("#divId").load(location.href + " #divId>*", "");

hope this may help someone to understand

You do not need to select the columns separately in order to use them in your CONCAT. Simply remove them, and your query will become:

SELECT FirstName AS First_Name
     , LastName AS Last_Name
     , CONCAT(ContactPhoneAreaCode1, ContactPhoneNumber1) AS Contact_Phone 
  FROM TABLE1

# this is comment
this isn't comment

is the way to do it. You can place it anywhere in the line and anything that comes later will be ignored

It could depend on your framework. (for each of them could exist an easier solution).

But to answer your question: there are a lot of external libraries for this functionality. Look here how to use apache commons fileupload.

This C# function uses a regular expression to evaluate whether the passed email address is syntactically valid or not.

public static bool isValidEmail(string inputEmail)
{
   string strRegex = @"^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}" +
         @"\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\" + 
         @".)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$";
   Regex re = new Regex(strRegex);
   if (re.IsMatch(inputEmail))
    return (true);
   else
    return (false);
}

You can try the following in PostgreSQL 9

DO $$DECLARE r record;
BEGIN
    FOR r IN SELECT tablename FROM pg_tables WHERE schemaname = 'public'
    LOOP
        EXECUTE 'alter table '|| r.tablename ||' owner to newowner;';
    END LOOP;
END$$;

I found the information found at http://help.infragistics.com/Help/NetAdvantage/jQuery/2013.1/CLR4.0/html/igOlapXmlaDataSource_Configuring_IIS_for_Cross_Domain_OLAP_Data.html to be very helpful in setting up HTTP OPTIONS for a WCF service in IIS 7.

I added the following to my web.config and then moved the OPTIONSVerbHandler in the IIS 7 'hander mappings' list to the top of the list. I also gave the OPTIONSVerbHander read access by double clicking the hander in the handler mappings section then on 'Request Restrictions' and then clicking on the access tab.

Unfortunately I quickly found that IE doesn't seem to support adding headers to their XDomainRequest object (setting the Content-Type to text/xml and adding a SOAPAction header).

Just wanted to share this as I spent the better part of a day looking for how to handle it.

<system.webServer>
    <httpProtocol>
        <customHeaders>
            <add name="Access-Control-Allow-Origin" value="*" />
            <add name="Access-Control-Allow-Methods" value="GET,POST,OPTIONS" />
            <add name="Access-Control-Allow-Headers" value="Content-Type, soapaction" />
        </customHeaders>
    </httpProtocol>
</system.webServer>

I think the easiest from a logical and efficiency point of view is using the queryset's exists() function, documented here:

https://docs.djangoproject.com/en/stable/ref/models/querysets/#django.db.models.query.QuerySet.exists

So in your example above I would simply write:

if User.objects.filter(email = cleaned_info['username']).exists():
    # at least one object satisfying query exists
else:
    # no object satisfying query exists

A big change that happened with Xcode 8 Beta 6 for Swift 3 was that id now imports as Any rather than AnyObject.

This means that parsedData is returned as a dictionary of most likely with the type [Any:Any]. Without using a debugger I could not tell you exactly what your cast to NSDictionary will do but the error you are seeing is because dict!["currently"]! has type Any

So, how do you solve this? From the way you've referenced it, I assume dict!["currently"]! is a dictionary and so you have many options:

First you could do something like this:

let currentConditionsDictionary: [String: AnyObject] = dict!["currently"]! as! [String: AnyObject]  

This will give you a dictionary object that you can then query for values and so you can get your temperature like this:

let currentTemperatureF = currentConditionsDictionary["temperature"] as! Double

Or if you would prefer you can do it in line:

let currentTemperatureF = (dict!["currently"]! as! [String: AnyObject])["temperature"]! as! Double

Hopefully this helps, I'm afraid I have not had time to write a sample app to test it.

One final note: the easiest thing to do, might be to simply cast the JSON payload into [String: AnyObject] right at the start.

let parsedData = try JSONSerialization.jsonObject(with: data as Data, options: .allowFragments) as! Dictionary<String, AnyObject>

Use this line to your Build gradle app

repositories {
    maven { url "http://jcenter.bintray.com" }}

Well, you wouldn't call cURL directly, rather, you'd use one of the following options:

• HttpWebRequest/HttpWebResponse
• WebClient
• HttpClient (available from .NET 4.5 on)

I'd highly recommend using the HttpClient class, as it's engineered to be much better (from a usability standpoint) than the former two.

In your case, you would do this:

using System.Net.Http;

var client = new HttpClient();

// Create the HttpContent for the form to be posted.
var requestContent = new FormUrlEncodedContent(new [] {
    new KeyValuePair<string, string>("text", "This is a block of text"),
});

// Get the response.
HttpResponseMessage response = await client.PostAsync(
    "http://api.repustate.com/v2/demokey/score.json",
    requestContent);

// Get the response content.
HttpContent responseContent = response.Content;

// Get the stream of the content.
using (var reader = new StreamReader(await responseContent.ReadAsStreamAsync()))
{
    // Write the output.
    Console.WriteLine(await reader.ReadToEndAsync());
}

Also note that the HttpClient class has much better support for handling different response types, and better support for asynchronous operations (and the cancellation of them) over the previously mentioned options.

Here.. Works perfectly for me

.modal-body { 
    max-height:500px; 
    overflow-y:auto;
}

An alternative to adding LINQ would be to use this code instead:

List<Pax_Detail> paxList = new List<Pax_Detail>(pax);

If $AccountNumber or $Balance is a node-set, then this behavior could easily happen. It's not because and is being treated as or.

For example, if $AccountNumber referred to nodes with the values 12345 and 66 and $Balance referred to nodes with the values 55 and 0, then $AccountNumber != '12345' would be true (because 66 is not equal to 12345) and $Balance != '0' would be true (because 55 is not equal to 0).

I'd suggest trying this instead:

<xsl:when test="not($AccountNumber = '12345' or $Balance = '0')">

$AccountNumber = '12345' or $Balance = '0' will be true any time there is an $AccountNumber with the value 12345 or there is a $Balance with the value 0, and if you apply not() to that, you will get a false result.

Use the command line.

touch /var/www/project1/html/phpinfo.php && echo '<?php phpinfo(); ?>' >> /var/www/project1/html/phpinfo.php && firefox --url localhost/project1/phpinfo.php

Something like that? Idk!

I resolved this problem by taking the full and transactional backup. Sometimes, the backup process is not completed and that's one of the reason the .ldf file is not getting shrink. Try this. It worked for me.

Easiest way for me is using Android Device Monitor to get the database file and SQLite DataBase Browser to view the file while still using Android Studio to program android.

1) Run and launch database app with Android emulator from Android Studio. (I inserted some data to database app to verify)

2) Run Android Device Monitor. How to run?; Go to [your_folder] > sdk >tools. You can see monitor.bat in that folder. shift + right click inside the folder and select "Open command window here". This action will launch command prompt. type monitor and Android Device Monitor will be launched.

3) Select the emulator that you are currently running. Then Go to data>data>[your_app_name]>databases

4) Click on the icon (located at top right corner) (hover on the icon and you will see "pull a file from the device") and save anywhere you like

5) Launch SQLite DataBase Browser. Drag and drop the file that you just saved into that Browser.

6) Go to Browse Data tab and select your table to view.

Just for the record solution that works across most database engines though might not be the most efficient:

Select Top (ReturnCount) *
From (
    Select Top (SkipCount + ReturnCount) *
    From SourceTable
    Order By ReverseSortCondition
) ReverseSorted
Order By SortCondition

Pelase note: the last page would still contain ReturnCount rows no matter what SkipCount is. But that might be a good thing in many cases.

You need to read from the configuration section manually before your code returns a JsonResult object. Simply read from web.config in single line:

        var jsonResult = Json(resultsForAjaxUI);
        jsonResult.MaxJsonLength = (ConfigurationManager.GetSection("system.web.extensions/scripting/webServices/jsonSerialization") as System.Web.Configuration.ScriptingJsonSerializationSection).MaxJsonLength;
        return jsonResult;

Be sure you defined configuration element in web.config

You miss the from clause

SELECT *  from TCCAWZTXD.TCC_COIL_DEMODATA WHERE CURRENT_INSERTTIME  BETWEEN(CURRENT_TIMESTAMP)-5 minutes AND CURRENT_TIMESTAMP

This page on MSDN lists standard DateTime format strings, uncluding strings using the 'Z'.

Update: you will need to make sure that the rest of the date string follows the correct pattern as well (you have not supplied an example of what you send it, so it's hard to say whether you did or not). For the UTC format to work it should look like this:

// yyyy'-'MM'-'dd HH':'mm':'ss'Z'
DateTime utcTime = DateTime.Parse("2009-05-07 08:17:25Z");

Use VideoView.

Natively ImageView does not support animated image. You have two options to show animated gif file

1. Use VideoView
2. Use ImageView and Split the gif file into several parts and then apply animation to it

tfs.visualstudio.com

This is what you wanted.

You could also set them to float to the right.

#ul_top_hypers li {
    float: right;
}

This allows them to still be block level, but will appear on the same line.

I will soon released a new version of my app to support to galaxy ace.

In order to solve your problem you should do this:

this._camera = Camera.open();     
this._camera.startPreview();
this._camera.autoFocus(new AutoFocusCallback() {
public void onAutoFocus(boolean success, Camera camera) {
}
});

Parameters params = this._camera.getParameters();
params.setFlashMode(Parameters.FLASH_MODE_ON);
this._camera.setParameters(params);

params = this._camera.getParameters();
params.setFlashMode(Parameters.FLASH_MODE_OFF);
this._camera.setParameters(params);

don't worry about FLASH_MODE_OFF because this will keep the light on, strange but it's true

to turn off the led just release the camera

I had this problem, setting copy local on and off etc did not work. The project was not using nuget so fixes around that were out of the question also.

The fix for me was to install MVC 3 (which I did through the web platform installer).

I suspect this will become more of a solution for people as the .net framework continues to advance and people don't have the older MVC stuff installed.

Also you can use concat like this :D

Insert into Table Value(CONCAT('JAVA ',CONCAT('& ', 'Oracle'));

FragmentActivity is part of the support library, while Activity is the framework's default class. They are functionally equivalent.

You should always use FragmentActivity and android.support.v4.app.Fragment instead of the platform default Activity and android.app.Fragment classes. Using the platform defaults mean that you are relying on whatever implementation of fragments is used in the device you are running on. These are often multiple years old, and contain bugs that have since been fixed in the support library.

In newer versions of OS X (especially Yosemite, EL Capitan), Apple has removed Java support for security reasons. To fix this you have to do the following.

1. Download Java for OS X 2015-001 from this link: https://support.apple.com/kb/dl1572?locale=en_US

2. Mount the disk image file and install Java 6 runtime for OS X.

   After this you should not be seeing any of the below messages:

   - Unable to find any JVMs matching version "(null)"

   - No Java runtime present, try --request to install.

   This should resolve the issue for the pop-up shown below:

You could also just use the old fashion 'strtok'

http://www.cplusplus.com/reference/clibrary/cstring/strtok/

Its a bit wonky but doesn't involve using boost (not that boost is a bad thing).

You basically call strtok with the string you want to split and the delimiter (in this case a space) and it will return you a char*.

From the link:

#include <stdio.h>
#include <string.h>

int main ()
{
  char str[] ="- This, a sample string.";
  char * pch;
  printf ("Splitting string \"%s\" into tokens:\n",str);
  pch = strtok (str," ,.-");
  while (pch != NULL)
  {
    printf ("%s\n",pch);
    pch = strtok (NULL, " ,.-");
  }
  return 0;
}

To get the location of a script being sourced, you can use utils::getSrcDirectory or utils::getSrcFilename. So changing the working directory to that of the current file can be done with:

setwd(getSrcDirectory()[1])

This does not work in RStudio if you Run the code rather than Sourceing it. For that, you need to use rstudioapi::getActiveDocumentContext.

setwd(dirname(rstudioapi::getActiveDocumentContext()$path))

This second solution requires that you are using RStudio as your IDE, of course.

let content = "<center><h1>404 Not Found</h1></center>"
let result = $("<div/>").html(content).text()

content: <center><h1>404 Not Found</h1></center>,
result: "404 Not Found"

Do you have access to your database, if so just open it up and look up the column and use an SQL call to retrieve the needed.

A short example on a form to retrieve data from a database table:

Form contain only a GataGridView named DataGrid

Database name: DB.mdf

Table name: DBtable

Column names in table: Name as varchar(50), Age as int, Gender as bit.

Private Sub DatabaseTest_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
    Public ConString As String = "Data Source=.\SQLEXPRESS;AttachDbFilename=C:\Users\{username}\documents\visual studio 2010\Projects\Userapplication prototype v1.0\Userapplication prototype v1.0\Database\DB.mdf;" & "Integrated Security=True;User Instance=True"
    Dim conn As New SqlClient.SqlConnection
    Dim cmd As New SqlClient.SqlCommand
    Dim da As New SqlClient.SqlDataAdapter
    Dim dt As New DataTable
    Dim sSQL As String = String.Empty
    Try
        conn = New SqlClient.SqlConnection(ConString)
        conn.Open() 'connects to the database
        cmd.Connection = conn
        cmd.CommandType = CommandType.Text
        sSQL = "SELECT * FROM DBtable" 'Sql to be executed
        cmd.CommandText = sSQL 'makes the string a command
        da.SelectCommand = cmd 'puts the command into the sqlDataAdapter
        da.Fill(dt) 'populates the dataTable by performing the command above
        Me.DataGrid.DataSource = dt 'Updates the grid using the populated dataTable

        'the following is only if any errors happen:
        If dt.Rows.Count = 0 Then
            MsgBox("No record found!")
        End If
    Catch ex As Exception
        MsgBox(ErrorToString)
    Finally
        conn.Close() 'closes the connection again so it can be accessed by other users or programs
    End Try
End Sub

This will fetch all the rows and columns from your database table for review.
If you want to only fetch the names just change the sql call with: "SELECT Name FROM DBtable" this way the DataGridView will only show the column names.

I'm only a rookie but i would strongly advise to get rid of theses auto generate wizards. Using SQL you have full access to your database and what happens.
Also one last thing, if your database doesn't use SQLClient just change it to OleDB.

Example: "Dim conn As New SqlClient.SqlConnection" becomes: Dim conn As New OleDb.OleDbConnection

Why stop at just the instance name? You can inventory your SQL Server environment with following:

SELECT  
    SERVERPROPERTY('ServerName') AS ServerName,  
    SERVERPROPERTY('MachineName') AS MachineName,
    CASE 
        WHEN  SERVERPROPERTY('InstanceName') IS NULL THEN ''
        ELSE SERVERPROPERTY('InstanceName')
    END AS InstanceName,
    '' as Port, --need to update to strip from Servername. Note: Assumes Registered Server is named with Port
    SUBSTRING ( (SELECT @@VERSION),1, CHARINDEX('-',(SELECT @@VERSION))-1 ) as ProductName,
    SERVERPROPERTY('ProductVersion') AS ProductVersion,  
    SERVERPROPERTY('ProductLevel') AS ProductLevel,
    SERVERPROPERTY('ProductMajorVersion') AS ProductMajorVersion,
    SERVERPROPERTY('ProductMinorVersion') AS ProductMinorVersion,
    SERVERPROPERTY('ProductBuild') AS ProductBuild,
    SERVERPROPERTY('Edition') AS Edition,
    CASE SERVERPROPERTY('EngineEdition')
        WHEN 1 THEN 'PERSONAL'
        WHEN 2 THEN 'STANDARD'
        WHEN 3 THEN 'ENTERPRISE'
        WHEN 4 THEN 'EXPRESS'
        WHEN 5 THEN 'SQL DATABASE'
        WHEN 6 THEN 'SQL DATAWAREHOUSE'
    END AS EngineEdition,  
    CASE SERVERPROPERTY('IsHadrEnabled')
        WHEN 0 THEN 'The Always On Availability Groups feature is disabled'
        WHEN 1 THEN 'The Always On Availability Groups feature is enabled'
        ELSE 'Not applicable'
    END AS HadrEnabled,
    CASE SERVERPROPERTY('HadrManagerStatus')
        WHEN 0 THEN 'Not started, pending communication'
        WHEN 1 THEN 'Started and running'
        WHEN 2 THEN 'Not started and failed'
        ELSE 'Not applicable'
    END AS HadrManagerStatus,
    CASE SERVERPROPERTY('IsSingleUser') WHEN 0 THEN 'No' ELSE 'Yes' END AS InSingleUserMode,
    CASE SERVERPROPERTY('IsClustered')
        WHEN 1 THEN 'Clustered'
        WHEN 0 THEN 'Not Clustered'
        ELSE 'Not applicable'

Unfortunately, Selenium was only built to work with Elements, not Text nodes.

If you try to use a function like get_element_by_xpath to target the text nodes, Selenium will throw an InvalidSelectorException.

One workaround is to grab the relevant HTML with Selenium and then use an HTML parsing library like BeautifulSoup that can handle text nodes more elegantly.

import bs4
from bs4 import BeautifulSoup

inner_html = driver.find_elements_by_css_selector('#a')[0].get_attribute("innerHTML")
inner_soup = BeautifulSoup(inner_html, 'html.parser')

outer_html = driver.find_elements_by_css_selector('#a')[0].get_attribute("outerHTML")
outer_soup = BeautifulSoup(outer_html, 'html.parser')

From there, there are several ways to search for the Text content. You'll have to experiment to see what works best for your use case.

Here's a simple one-liner that may be sufficient:

inner_soup.find(text=True)

If that doesn't work, then you can loop through the element's child nodes with .contents() and check their object type.

BeautifulSoup has four types of elements, and the one that you'll be interested in is the NavigableString type, which is produced by Text nodes. By contrast, Elements will have a type of Tag.

contents = inner_soup.contents

for bs4_object in contents:

    if (type(bs4_object) == bs4.Tag):
        print("This object is an Element.")

    elif (type(bs4_object) == bs4.NavigableString):
        print("This object is a Text node.")

Note that BeautifulSoup doesn't support Xpath expressions. If you need those, then you can use some of the workarounds in this thread.

Ubuntu 10.04 comes with the Suhosin patch only, which does not give you configuration options. But you can install php5-suhosin to solve this:

apt-get update
apt-get install php5-suhosin

Now you can edit /etc/php5/conf.d/suhosin.ini and set:

suhosin.memory_limit = 1G

Then using ini_set will work in a script:

ini_set('memory_limit', '256M');

If your actual concern is the dynamicness of the webapp context (the "AppName" part), then just retrieve it dynamically by HttpServletRequest#getContextPath().

<head>
    <link rel="stylesheet" href="${pageContext.request.contextPath}/templates/style/main.css" />
    <script src="${pageContext.request.contextPath}/templates/js/main.js"></script>
    <script>var base = "${pageContext.request.contextPath}";</script>
</head>
<body>
    <a href="${pageContext.request.contextPath}/pages/foo.jsp">link</a>
</body>

If you want to set a base path for all relative links so that you don't need to repeat ${pageContext.request.contextPath} in every relative link, use the <base> tag. Here's an example with help of JSTL functions.

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>
...
<head>
    <c:set var="url">${pageContext.request.requestURL}</c:set>
    <base href="${fn:substring(url, 0, fn:length(url) - fn:length(pageContext.request.requestURI))}${pageContext.request.contextPath}/" />
    <link rel="stylesheet" href="templates/style/main.css" />
    <script src="templates/js/main.js"></script>
    <script>var base = document.getElementsByTagName("base")[0].href;</script>
</head>
<body>
    <a href="pages/foo.jsp">link</a>
</body>

This way every relative link (i.e. not starting with / or a scheme) will become relative to the <base>.

This is by the way not specifically related to Tomcat in any way. It's just related to HTTP/HTML basics. You would have the same problem in every other webserver.

See also:

• Browser can't access/find relative resources like CSS, images and links when calling a Servlet which forwards to a JSP
• Is it recommended to use the <base> html tag?

A simpler way to replace the diacriticals.

function replaceDiacritics(str){

  var diacritics = [
    {char: 'A', base: /[\300-\306]/g},
    {char: 'a', base: /[\340-\346]/g},
    {char: 'E', base: /[\310-\313]/g},
    {char: 'e', base: /[\350-\353]/g},
    {char: 'I', base: /[\314-\317]/g},
    {char: 'i', base: /[\354-\357]/g},
    {char: 'O', base: /[\322-\330]/g},
    {char: 'o', base: /[\362-\370]/g},
    {char: 'U', base: /[\331-\334]/g},
    {char: 'u', base: /[\371-\374]/g},
    {char: 'N', base: /[\321]/g},
    {char: 'n', base: /[\361]/g},
    {char: 'C', base: /[\307]/g},
    {char: 'c', base: /[\347]/g}
  ]

  diacritics.forEach(function(letter){
    str = str.replace(letter.base, letter.char);
  });

  return str;
};

Jbuilder is a gem built by rails community. But it works well in non-rails environments and have a cool set of features.

# suppose we have a sample object as below
sampleObj.name #=> foo
sampleObj.last_name #=> bar

# using jbuilder we can convert it to json:
Jbuilder.encode do |json|
  json.name sampleObj.name
  json.last_name sampleObj.last_name
end #=> "{:\"name\" => \"foo\", :\"last_name\" => \"bar\"}"

If you add all your events with this snippet of code:

//put this somewhere in your JavaScript:
HTMLElement.prototype.addEvent = function(event, callback){
  if(!this.events)this.events = {};
  if(!this.events[event]){
    this.events[event] = [];
    var element = this;
    this['on'+event] = function(e){
      var events = element.events[event];
      for(var i=0;i<events.length;i++){
        events[i](e||event);
      }
    }
  }
  this.events[event].push(callback);
}
//use like this:
element.addEvent('change', function(e){...});

then you can just use element.on<EVENTNAME>() where <EVENTNAME> is the name of your event, and that will call all events with <EVENTNAME>

I prefer to do the following one-liner, in POSIX shell compatible format:

$ [ -f "/$DIR/$FILE" ] || echo "$FILE NOT FOUND"

$ [ -f "/$DIR/$FILE" ] && echo "$FILE FOUND"

For a couple of commands, like I would do in a script:

$  [ -f "/$DIR/$FILE" ] || { echo "$FILE NOT FOUND" ; exit 1 ;}

Once I started doing this, I rarely use the fully typed syntax anymore!!

UPDATE: I have created a video on sending multipart/form-data requests to explain this better.

Actually, Postman can do this. Here is a screenshot

Newer version : Screenshot captured from postman chrome extension

Another version

Older version

Make sure you check the comment from @maxkoryukov

Be careful with explicit Content-Type header. Better - do not set it's value, the Postman is smart enough to fill this header for you. BUT, if you want to set the Content-Type: multipart/form-data - do not forget about boundary field.

How about this?

$("b").insertAdjacentHTML("afterend",$("b").innerHTML);
$("b").parentNode.removeChild($("b"));

The first line copies the HTML contents of the b tag to the location directly after the b tag, and then the second line removes the b tag from the DOM, leaving only its copied contents.

I normally wrap this into a function to make it easier to use:

function removeElementTags(element) {
   element.insertAdjacentHTML("afterend",element.innerHTML);
   element.parentNode.removeChild(element);
}

All of the code is actually pure Javascript, the only JQuery being used is that to select the element to target (the b tag in the first example). The function is just pure JS :D

Also look at:

• https://developer.mozilla.org/en-US/docs/Web/API/Element/insertAdjacentHTML

Empty slice and nil slice are initialized differently in Go:

var nilSlice []int 
emptySlice1 := make([]int, 0)
emptySlice2 := []int{}

fmt.Println(nilSlice == nil)    // true
fmt.Println(emptySlice1 == nil) // false
fmt.Println(emptySlice2 == nil) // false

As for all three slices, len and cap are 0.

One option, if you're looking for the actual queried page, rather than the page ID or slug is to intercept the query:

add_action('parse_request', 'show_query', 10, 1);

Within your function, you have access to the $wp object and you can get either the pagename or the post name with:

function show_query($wp){
     if ( ! is_admin() ){ // heck we don't need the admin pages
         echo $wp->query_vars['pagename'];
         echo $wp->query_vars['name'];
     }
}

If, on the other hand, you really need the post data, the first place to get it (and arguably in this context, the best) is:

add_action('wp', 'show_page_name', 10, 1);

function show_page_name($wp){
     if ( ! is_admin() ){
        global $post;
        echo $post->ID, " : ", $post->post_name;
     }
}

Finally, I realize this probably wasn't the OP's question, but if you're looking for the Admin page name, use the global $pagenow.

For linux users, you should know the following:

1. $CLASSPATH is specifically what Java uses to look through multiple directories to find all the different classes it needs for your script (unless you explicitly tell it otherwise with the -cp override). Using -cp (--classpath) requires that you keep track of all the directories manually and copy-paste that line every time you run the program (not preferable IMO).

2. The colon (":") character separates the different directories. There is only one $CLASSPATH and it has all the directories in it. So, when you run "export CLASSPATH=...." you want to include the current value "$CLASSPATH" in order to append to it. For example:

   export CLASSPATH=.
   export CLASSPATH=$CLASSPATH:/usr/share/java/mysql-connector-java-5.1.12.jar
   

   In the first line above, you start CLASSPATH out with just a simple 'dot' which is the path to your current working directory. With that, whenever you run java it will look in the current working directory (the one you're in) for classes. In the second line above, $CLASSPATH grabs the value that you previously entered (.) and appends the path to a mysql dirver. Now, java will look for the driver AND for your classes.

3. echo $CLASSPATH
   

   is super handy, and what it returns should read like a colon-separated list of all the directories you want java looking in for what it needs to run your script.

4. Tomcat does not use CLASSPATH. Read what to do about that here: https://tomcat.apache.org/tomcat-8.0-doc/class-loader-howto.html

Float property is actually not used to align the text.

This property is used to add element to either right or left or center.

div > div { border: 1px solid black;}

<html>_x000D_
     <div>_x000D_
         <div style="float:left">First</div>_x000D_
         <div style="float:left">Second</div>_x000D_
         <div style="float:left">Third</div>_x000D_
_x000D_
         <div style="float:right">First</div>_x000D_
         <div style="float:right">Second</div>_x000D_
         <div style="float:right">Third</div>_x000D_
     </div>_x000D_
</html>

for float:left output will be [First][second][Third]

for float:right output will be [Third][Second][First]

That means float => left property will add your next element to left of previous one, Same case with right

Also you have to Consider the width of parent element, if the sum of widths of child elements exceed the width of parent element then the next element will be added at next line

 <html>_x000D_
     <div style="width:100%">_x000D_
       <div style="float:left;width:50%">First</div>_x000D_
       <div style="float:left;width:50%">Second</div>_x000D_
       <div style="float:left;width:50%">Third</div>_x000D_
     </div>_x000D_
</html>

[First] [Second]

[Third]

So you need to Consider All these aspect to get the perfect result

When learning a new language, there are some nice problem sets you can use to learn the language better.

• Project Euler has some nice problems with a strong mathematical twist.
• Practice on Google Code Jam past problems, stick to the qualification rounds for the easier problems

For Spring 4, using Spring Boot we can have the following example without using the anti-pattern of getting the Bean from the ApplicationContext directly:

package com.yourproject;

@SpringBootApplication
public class TestBed implements CommandLineRunner {

    private MyService myService;

    @Autowired
    public TestBed(MyService myService){
        this.myService = myService;
    }

    public static void main(String... args) {
        SpringApplication.run(TestBed.class, args);
    }

    @Override
    public void run(String... strings) throws Exception {
        System.out.println("myService: " + MyService );
    }

}

@Service 
public class MyService{
    public String getSomething() {
        return "something";
    }
}

Make sure that all your injected services are under com.yourproject or its subpackages.

Put the values you need someplace where the other script can retrieve them, like a hidden input, and then pull those values from their container when you initialize your new script. You could even put all your params as a JSON string into one hidden field.

Always : If you always want vertical scrollbar, use overflow-y: scroll;

jsFiddle:

<div style="overflow-y: scroll;">
......
</div>

When needed: If you only want vertical scrollbar when needed, use overflow-y: auto; (You need to specify a height in this case)

jsFiddle:

<div style="overflow-y: auto; height:150px; ">
....
</div>

Yes, that is supported.

Check the documentation provided here for the supported keywords inside method names.

You can just define the method in the repository interface without using the @Query annotation and writing your custom query. In your case it would be as followed:

List<Inventory> findByIdIn(List<Long> ids);

I assume that you have the Inventory entity and the InventoryRepository interface. The code in your case should look like this:

The Entity

@Entity
public class Inventory implements Serializable {

  private static final long serialVersionUID = 1L;

  private Long id;

  // other fields
  // getters/setters

}

The Repository

@Repository
@Transactional
public interface InventoryRepository extends PagingAndSortingRepository<Inventory, Long> {

  List<Inventory> findByIdIn(List<Long> ids);

}

MySQL 5.x specification for decimal datatype is: DECIMAL[(M[,D])] [UNSIGNED] [ZEROFILL]. The answer above is wrong (now corrected) in saying that unsigned decimals are not possible.

To define a field allowing only unsigned decimals, with a total length of 6 digits, 4 of which are decimals, you would use: DECIMAL (6,4) UNSIGNED.

You can likewise create unsigned (ie. not negative) FLOAT and DOUBLE datatypes.

Update on MySQL 8.0.17+, as in MySQL 8 Manual: 11.1.1 Numeric Data Type Syntax:

"Numeric data types that permit the UNSIGNED attribute also permit SIGNED. However, these data types are signed by default, so the SIGNED attribute has no effect.*

As of MySQL 8.0.17, the UNSIGNED attribute is deprecated for columns of type FLOAT, DOUBLE, and DECIMAL (and any synonyms); you should expect support for it to be removed in a future version of MySQL. Consider using a simple CHECK constraint instead for such columns.

It has a -force parameter.????

foo = {'a':1, 'b':2, 'c':3, 'd':4, 'e':5, 'f':6}
iterator = iter(foo.items())
for i in range(3):
    print(next(iterator))

Basically, turn the view (dict_items) into an iterator, and then iterate it with next().

Here's one very simple example:

var counter = 0;

function getSlug(tokens) {
    var slug = '';

    if (!!tokens.length) {
        slug = tokens.shift();
        slug = slug.toLowerCase();
        slug += getSlug(tokens);

        counter += 1;
        console.log('THE SLUG ELEMENT IS: %s, counter is: %s', slug, counter);
    }

    return slug;
}

var mySlug = getSlug(['This', 'Is', 'My', 'Slug']);
console.log('THE SLUG IS: %s', mySlug);

Notice that the counter counts "backwards" in regards to what slug's value is. This is because of the position at which we are logging these values, as the function recurs before logging -- so, we essentially keep nesting deeper and deeper into the call-stack before logging takes place.

Once the recursion meets the final call-stack item, it trampolines "out" of the function calls, whereas, the first increment of counter occurs inside of the last nested call.

I know this is not a "fix" on the Questioner's code, but given the title I thought I'd generically exemplify Recursion for a better understanding of recursion, outright.

The easiest way to get the correct number of hours between two dates (datetimes), even across daylight saving time changes, is to use the difference in Unix timestamps. Unix timestamps are seconds elapsed since 1970-01-01T00:00:00 UTC, ignoring leap seconds (this is OK because you probably don't need this precision, and because it's quite difficult to take leap seconds into account).

The most flexible way to convert a datetime string with optional timezone information into a Unix timestamp is to construct a DateTime object (optionally with a DateTimeZone as a second argument in the constructor), and then call its getTimestamp method.

$str1 = '2006-04-12 12:30:00'; 
$str2 = '2006-04-14 11:30:00';
$tz1 = new DateTimeZone('Pacific/Apia');
$tz2 = $tz1;
$d1 = new DateTime($str1, $tz1); // tz is optional,
$d2 = new DateTime($str2, $tz2); // and ignored if str contains tz offset
$delta_h = ($d2->getTimestamp() - $d1->getTimestamp()) / 3600;
if ($rounded_result) {
   $delta_h = round ($delta_h);
} else if ($truncated_result) {
   $delta_h = intval($delta_h);
}
echo "?h: $delta_h\n";

I just planned to share some knowledge.

Deadlocks A set of threads/processes is deadlocked, if each thread/process in the set is waiting for an event that only another process in the set can cause.

The important thing here is another process is also in the same set. that means another process also blocked and no one can proceed.

Deadlocks occur when processes are granted exclusive access to resources.

These four conditions should be satisfied to have a deadlock.

1. Mutual exclusion condition (Each resource is assigned to 1 process)
2. Hold and wait condition (Process holding resources and at the same time it can ask other resources).
3. No preemption condition (Previously granted resources can not forcibly be taken away) #This condition depends on the application
4. Circular wait condition (Must be a circular chain of 2 or more processes and each is waiting for resource held by the next member of the chain) # It will happen dynamically

If we found these conditions then we can say there may be occurred a situation like a deadlock.

LiveLock

Each thread/process is repeating the same state again and again but doesn't progress further. Something similar to a deadlock since the process can not enter the critical section. However in a deadlock, processes are wait without doing anything but in livelock, the processes are trying to proceed but processes are repeated to the same state again and again.

(In a deadlocked computation there is no possible execution sequence which succeeds. but In a livelocked computation, there are successful computations, but there are one or more execution sequences in which no process enters its critical section.)

Difference from deadlock and livelock

When deadlock happens, No execution will happen. but in livelock, some executions will happen but those executions are not enough to enter the critical section.

The only thing that worked for me -i command line argument.

Just put all your python code inside a .py file and then run the following command;

python -i script.py

It means that if you set -i variable and run your module then python doesn't exit on SystemExit. Read more at the this link.

Do a request with curl and see if it returns a 404 status code. Do the request using the HEAD request method so it only returns the headers without a body.

Just as Daniel said "Git and TFVC are the two source control options in TFS". Fortunately both are supported for now in VS Code.

You need to install the Azure Repos Extension for Visual Studio Code. The process of installing is pretty straight forward.

1. Search for Azure Repos in VS Code and select to install the one by Microsoft
2. Open File -> Preferences -> Settings

3. Add the following lines to your user settings

   If you have VS 2015 installed on your machine, your path to Team Foundation tool (tf.exe) may look like this:

   {
       "tfvc.location": "C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\Common7\\IDE\\tf.exe",
       "tfvc.restrictWorkspace": true
   }

   Or for VS 2017:

   {
       "tfvc.location": "C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\Enterprise\\Common7\\IDE\\CommonExtensions\\Microsoft\\TeamFoundation\\Team Explorer\\tf.exe",
       "tfvc.restrictWorkspace": true
   }

4. Open a local folder (repository), From View -> Command Pallette ..., type team signin

5. Provide user name --> Enter --> Provide password to connect to TFS.

Please refer to below links for more details:

• Using Visual Studio Code & Team Foundation Version Control (TFVC)
• Team Foundation Version Control (TFVC) Support
• Using Version Control in VS Code

So I found a pretty good answer at this link: https://www.thomasmaurer.ch/2011/03/powershell-search-for-string-or-grep-for-powershell/

But essentially it is:

Select-String -Path "C:\file\Path\*.txt" -Pattern "^Enter REGEX Here$"

This gives a directory file search (*or you can just specify a file) and a file-content search all in one line of PowerShell, very similar to grep. The output will be similar to:

doc.txt:31: Enter REGEX Here
HelloWorld.txt:13: Enter REGEX Here

I implemented a Hive Data platform recently in my firm and can speak to it in first person since I was a one man team.

Objective

1. To have the daily web log files collected from 350+ servers daily queryable thru some SQL like language
2. To replace daily aggregation data generated thru MySQL with Hive
3. Build Custom reports thru queries in Hive

Architecture Options

I benchmarked the following options:

1. Hive+HDFS
2. Hive+HBase - queries were too slow so I dumped this option

Design

1. Daily log Files were transported to HDFS
2. MR jobs parsed these log files and output files in HDFS
3. Create Hive tables with partitions and locations pointing to HDFS locations
4. Create Hive query scripts (call it HQL if you like as diff from SQL) that in turn ran MR jobs in the background and generated aggregation data
5. Put all these steps into an Oozie workflow - scheduled with Daily Oozie Coordinator

Summary

HBase is like a Map. If you know the key, you can instantly get the value. But if you want to know how many integer keys in Hbase are between 1000000 and 2000000 that is not suitable for Hbase alone.

If you have data that needs to be aggregated, rolled up, analyzed across rows then consider Hive.

Hopefully this helps.

Hive actually rocks ...I know, I have lived it for 12 months now... So does HBase...

The return statement only makes sense inside functions:

def foo():
    while True:
        return False

I was able to add an app icon to my react-native android project by following this guy's advice and using Android Asset Studio

Here it is, transcribed in case the link goes dead:

How to upload an Application Icon in React-Native Android

1) Upload your image to Android Asset Studio. Pick whatever effects you’d like to apply. The tool generates a zip file for you. Click Download .Zip.

2) Unzip the file on your machine. Then drag over the images you want to your /android/app/src/main/res/ folder. Make sure to put each image in the right subfolder mipmap-{hdpi, mdpi, xhdpi, xxhdpi, xxxhdpi}.

3) Do not (as I originally did) naively drag and drop the whole folder over your res folder. As you may be removing your /res/values/{strings,styles}.xml files altogether.

    // This is for first date

    document.write((first.getTime())/1000); // get the actual epoch values
    second = new Date(2012, 03, 08, 15, 30, 10); // Get the first date epoch object
    document.write((second.getTime())/1000); // get the actual epoch values

    if ( diff/ one_day_epoch > 365 ) // check , is it exceei
    {
    alert( 'date is exceeding one year');
    }

For your first method change ws.Range("A") to ws.Range("A:A") which will search the entirety of column a, like so:

Sub Find_Bingo()

        Dim wb As Workbook
        Dim ws As Worksheet
        Dim FoundCell As Range
        Set wb = ActiveWorkbook
        Set ws = ActiveSheet

            Const WHAT_TO_FIND As String = "Bingo"

            Set FoundCell = ws.Range("A:A").Find(What:=WHAT_TO_FIND)
            If Not FoundCell Is Nothing Then
                MsgBox (WHAT_TO_FIND & " found in row: " & FoundCell.Row)
            Else
                MsgBox (WHAT_TO_FIND & " not found")
            End If
End Sub

For your second method, you are using Bingo as a variable instead of a string literal. This is a good example of why I add Option Explicit to the top of all of my code modules, as when you try to run the code it will direct you to this "variable" which is undefined and not intended to be a variable at all.

Additionally, when you are using With...End With you need a period . before you reference Cells, so Cells should be .Cells. This mimics the normal qualifying behavior (i.e. Sheet1.Cells.Find..)

Change Bingo to "Bingo" and change Cells to .Cells

With Sheet1
        Set FoundCell = .Cells.Find(What:="Bingo", After:=.Cells(1, 1), _
        LookIn:=xlValues, lookat:=xlPart, SearchOrder:=xlByRows, _
        SearchDirection:=xlNext, MatchCase:=False, SearchFormat:=False)
    End With

If Not FoundCell Is Nothing Then
        MsgBox ("""Bingo"" found in row " & FoundCell.Row)
Else
        MsgBox ("Bingo not found")
End If

Update

In my

With Sheet1
    .....
End With

The Sheet1 refers to a worksheet's code name, not the name of the worksheet itself. For example, say I open a new blank Excel workbook. The default worksheet is just Sheet1. I can refer to that in code either with the code name of Sheet1 or I can refer to it with the index of Sheets("Sheet1"). The advantage to using a codename is that it does not change if you change the name of the worksheet.

Continuing this example, let's say I renamed Sheet1 to Data. Using Sheet1 would continue to work, as the code name doesn't change, but now using Sheets("Sheet1") would return an error and that syntax must be updated to the new name of the sheet, so it would need to be Sheets("Data").

In the VB Editor you would see something like this:

Notice how, even though I changed the name to Data, there is still a Sheet1 to the left. That is what I mean by codename.

The Data worksheet can be referenced in two ways:

Debug.Print Sheet1.Name
Debug.Print Sheets("Data").Name

Both should return Data

More discussion on worksheet code names can be found here.

You want to use:

git checkout --ours foo/bar.java
git add foo/bar.java

If you rebase a branch feature_x against main (i.e. running git rebase main while on branch feature_x), during rebasing ours refers to main and theirs to feature_x.

As pointed out in the git-rebase docs:

Note that a rebase merge works by replaying each commit from the working branch on top of the branch. Because of this, when a merge conflict happens, the side reported as ours is the so-far rebased series, starting with <upstream>, and theirs is the working branch. In other words, the sides are swapped.

For further details read this thread.

<context:annotation-config> is used to activate annotations in beans already registered in the application context (no matter if they were defined with XML or by package scanning).

<context:component-scan> can also do what <context:annotation-config> does but <context:component-scan> also scans packages to find and register beans within the application context.

I'll use some examples to show the differences/similarities.

Lets start with a basic setup of three beans of type A, B and C, with B and C being injected into A.

package com.xxx;
public class B {
  public B() {
    System.out.println("creating bean B: " + this);
  }
}

package com.xxx;
public class C {
  public C() {
    System.out.println("creating bean C: " + this);
  }
}

package com.yyy;
import com.xxx.B;
import com.xxx.C;
public class A { 
  private B bbb;
  private C ccc;
  public A() {
    System.out.println("creating bean A: " + this);
  }
  public void setBbb(B bbb) {
    System.out.println("setting A.bbb with " + bbb);
    this.bbb = bbb;
  }
  public void setCcc(C ccc) {
    System.out.println("setting A.ccc with " + ccc);
    this.ccc = ccc; 
  }
}

With the following XML configuration :

<bean id="bBean" class="com.xxx.B" />
<bean id="cBean" class="com.xxx.C" />
<bean id="aBean" class="com.yyy.A">
  <property name="bbb" ref="bBean" />
  <property name="ccc" ref="cBean" />
</bean>

Loading the context produces the following output:

creating bean B: com.xxx.B@c2ff5
creating bean C: com.xxx.C@1e8a1f6
creating bean A: com.yyy.A@1e152c5
setting A.bbb with com.xxx.B@c2ff5
setting A.ccc with com.xxx.C@1e8a1f6

OK, this is the expected output. But this is "old style" Spring. Now we have annotations so lets use those to simplify the XML.

First, lets autowire the bbb and ccc properties on bean A like so:

package com.yyy;
import org.springframework.beans.factory.annotation.Autowired;
import com.xxx.B;
import com.xxx.C;
public class A { 
  private B bbb;
  private C ccc;
  public A() {
    System.out.println("creating bean A: " + this);
  }
  @Autowired
  public void setBbb(B bbb) {
    System.out.println("setting A.bbb with " + bbb);
    this.bbb = bbb;
  }
  @Autowired
  public void setCcc(C ccc) {
    System.out.println("setting A.ccc with " + ccc);
    this.ccc = ccc;
  }
}

This allows me to remove the following rows from the XML:

<property name="bbb" ref="bBean" />
<property name="ccc" ref="cBean" />

My XML is now simplified to this:

<bean id="bBean" class="com.xxx.B" />
<bean id="cBean" class="com.xxx.C" />
<bean id="aBean" class="com.yyy.A" />

When I load the context I get the following output:

creating bean B: com.xxx.B@5e5a50
creating bean C: com.xxx.C@54a328
creating bean A: com.yyy.A@a3d4cf

OK, this is wrong! What happened? Why aren't my properties autowired?

Well, annotations are a nice feature but by themselves they do nothing whatsoever. They just annotate stuff. You need a processing tool to find the annotations and do something with them.

<context:annotation-config> to the rescue. This activates the actions for the annotations that it finds on the beans defined in the same application context where itself is defined.

If I change my XML to this:

<context:annotation-config />
<bean id="bBean" class="com.xxx.B" />
<bean id="cBean" class="com.xxx.C" />
<bean id="aBean" class="com.yyy.A" />

when I load the application context I get the proper result:

creating bean B: com.xxx.B@15663a2
creating bean C: com.xxx.C@cd5f8b
creating bean A: com.yyy.A@157aa53
setting A.bbb with com.xxx.B@15663a2
setting A.ccc with com.xxx.C@cd5f8b

OK, this is nice, but I've removed two rows from the XML and added one. That's not a very big difference. The idea with annotations is that it's supposed to remove the XML.

So let's remove the XML definitions and replace them all with annotations:

package com.xxx;
import org.springframework.stereotype.Component;
@Component
public class B {
  public B() {
    System.out.println("creating bean B: " + this);
  }
}

package com.xxx;
import org.springframework.stereotype.Component;
@Component
public class C {
  public C() {
    System.out.println("creating bean C: " + this);
  }
}

package com.yyy;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import com.xxx.B;
import com.xxx.C;
@Component
public class A { 
  private B bbb;
  private C ccc;
  public A() {
    System.out.println("creating bean A: " + this);
  }
  @Autowired
  public void setBbb(B bbb) {
    System.out.println("setting A.bbb with " + bbb);
    this.bbb = bbb;
  }
  @Autowired
  public void setCcc(C ccc) {
    System.out.println("setting A.ccc with " + ccc);
    this.ccc = ccc;
  }
}

While in the XML we only keep this:

<context:annotation-config />

We load the context and the result is... Nothing. No beans are created, no beans are autowired. Nothing!

That's because, as I said in the first paragraph, the <context:annotation-config /> only works on beans registered within the application context. Because I removed the XML configuration for the three beans there is no bean created and <context:annotation-config /> has no "targets" to work on.

But that won't be a problem for <context:component-scan> which can scan a package for "targets" to work on. Let's change the content of the XML config into the following entry:

<context:component-scan base-package="com.xxx" />

When I load the context I get the following output:

creating bean B: com.xxx.B@1be0f0a
creating bean C: com.xxx.C@80d1ff

Hmmmm... something is missing. Why?

If you look closelly at the classes, class A has package com.yyy but I've specified in the <context:component-scan> to use package com.xxx so this completely missed my A class and only picked up B and C which are on the com.xxx package.

To fix this, I add this other package also:

<context:component-scan base-package="com.xxx,com.yyy" />

and now we get the expected result:

creating bean B: com.xxx.B@cd5f8b
creating bean C: com.xxx.C@15ac3c9
creating bean A: com.yyy.A@ec4a87
setting A.bbb with com.xxx.B@cd5f8b
setting A.ccc with com.xxx.C@15ac3c9

And that's it! Now you don't have XML definitions anymore, you have annotations.

As a final example, keeping the annotated classes A, B and C and adding the following to the XML, what will we get after loading the context?

<context:component-scan base-package="com.xxx" />
<bean id="aBean" class="com.yyy.A" />

We still get the correct result:

creating bean B: com.xxx.B@157aa53
creating bean C: com.xxx.C@ec4a87
creating bean A: com.yyy.A@1d64c37
setting A.bbb with com.xxx.B@157aa53
setting A.ccc with com.xxx.C@ec4a87

Even if the bean for class A isn't obtained by scanning, the processing tools are still applied by <context:component-scan> on all beans registered in the application context, even for A which was manually registered in the XML.

But what if we have the following XML, will we get duplicated beans because we've specified both <context:annotation-config /> and <context:component-scan>?

<context:annotation-config />
<context:component-scan base-package="com.xxx" />
<bean id="aBean" class="com.yyy.A" />

No, no duplications, We again get the expected result:

creating bean B: com.xxx.B@157aa53
creating bean C: com.xxx.C@ec4a87
creating bean A: com.yyy.A@1d64c37
setting A.bbb with com.xxx.B@157aa53
setting A.ccc with com.xxx.C@ec4a87

That's because both tags register the same processing tools (<context:annotation-config /> can be omitted if <context:component-scan> is specified) but Spring takes care of running them only once.

Even if you register the processing tools yourself multiple times, Spring will still make sure they do their magic only once; this XML:

<context:annotation-config />
<context:component-scan base-package="com.xxx" />
<bean id="aBean" class="com.yyy.A" />
<bean id="bla" class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor" />
<bean id="bla1" class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor" />
<bean id="bla2" class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor" />
<bean id="bla3" class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor" />

will still generate the following result:

creating bean B: com.xxx.B@157aa53
creating bean C: com.xxx.C@ec4a87
creating bean A: com.yyy.A@25d2b2
setting A.bbb with com.xxx.B@157aa53
setting A.ccc with com.xxx.C@ec4a87

OK, that about raps it up.

I hope this information along with the responses from @Tomasz Nurkiewicz and @Sean Patrick Floyd are all you need to understand how <context:annotation-config> and <context:component-scan> work.

If you ran into this issue when using TypeScript, you may need to add skipLibCheck: true in your tsconfig.json file.

You can also just download and run ez_setup.py, though the SetupTools documentation no longer suggests this. Worked fine for me as recently as 2 weeks ago.
