If you only need to compare schemas (not data), and have access to Perl, mysqldiff might work. I've used it because it lets you compare local databases to remote databases (via SSH), so you don't need to bother dumping any data.

http://adamspiers.org/computing/mysqldiff/

It will attempt to generate SQL queries to synchronize two databases, but I don't trust it (or any tool, actually). As far as I know, there's no 100% reliable way to reverse-engineer the changes needed to convert one database schema to another, especially when multiple changes have been made.

For example, if you change only a column's type, an automated tool can easily guess how to recreate that. But if you also move the column, rename it, and add or remove other columns, the best any software package can do is guess at what probably happened. And you may end up losing data.

I'd suggest keeping track of any schema changes you make to the development server, then running those statements by hand on the live server (or rolling them into an upgrade script or migration). It's more tedious, but it'll keep your data safe. And by the time you start allowing end users access to your site, are you really going to be making constant heavy database changes?

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

If you are not comfortable with bash, you can continue to work in a standard windows command (i.e. DOS) shell.

For this to work you must add C:\cygwin\bin (or your local alternative) to the Windows PATH variable.

With this done, you may: 1) Open a command (DOS) shell 2) Change the directory to the location of your code (c:, then cd path\to\file) 3) gcc myProgram.c -o myProgram

As mentioned in nik's response, the "Using Cygwin" documentation is a great place to learn more.

if you just want the ip address try this:

I am currently working on this, and i have already a number of solutions. It is nice to have a high quality site, that i can use also for my convenience. Because if you do not write these things down, you will eventually forget some parts. And i can also recommend writing some basic's down if you are starting any kind of new programming/design.

So if the float functions are causing problems there is a couple of options you can try.

One is modify the div alignment in the div tag it self like so <div class="kosher" align=left> If this does not suit you then there is another option with margin like so.

.leftdiv {
    display: inline-block;
    width: 40%;
    float: left;
}
.rightdiv {
    display: block;
    margin-right: 20px;
    margin-left: 45%;
}

Don't forget to remove the <div align=left>.

CSS, HTML:

div.mydiv {width: 200px; margin: 0 auto}

<div class="mydiv">_x000D_
    _x000D_
    I am in the middle_x000D_
    _x000D_
</div>

Your diagram shows a block level element also (which a div usually is), not an inline one.

Of the top of my head, min-width is supported in FF2+/Safari3+/IE7+. Can be done for IE6 using hackety CSS, or a simple bit of JS.

Just to expand on @T.J. Crowder's answer.

json_encode does well with simple html strings, in my experience however json_encode often becomes confused by, (or it becomes quite difficult to properly escape) longer complex nested html mixed with php. Two options to consider if you are in this position are: encoding/decoding the markup first with something like [base64_encode][1]/ decode (quite a bit of a performance hit), or (and perhaps preferably) be more selective in what you are passing via json, and generate the necessary markup on the client side instead.

Here's an O(n) solution:

function hasDupes(arr) {
  /* temporary object */
  var uniqOb = {};
  /* create object attribute with name=value in array, this will not keep dupes*/
  for (var i in arr)
    uniqOb[arr[i]] = "";
  /* if object's attributes match array, then no dupes! */
  if (arr.length == Object.keys(uniqOb).length)
    alert('NO dupes');
  else
    alert('HAS dupes');


}
var arr = ["1/1/2016", "1/1/2016", "2/1/2016"];
hasDupes(arr);

There is an express version on SSMS that has considerably fewer features but still has the basics.

Install the NuGet package called SevenZipSharp.Interop

Then:

SevenZipBase.SetLibraryPath(@".\x86\7z.dll");
var compressor = new SevenZip.SevenZipCompressor();
var filesToCompress = Directory.GetFiles(@"D:\data\");
compressor.CompressFiles(@"C:\archive\abc.7z", filesToCompress);

You can't do it in HTML. You can in CSS. Create a new CSS file and write:

p {
 font-size: (some number);
}

If that doesn't work make sure you don't have any "pre" tags, which make your code a bit smaller.

Make a JavaScript control that before the submit cheek that the selected option is different to your first option

<?php
if (!isset($_GET) || empty($_GET))
{
    // do stuff here
}

In my opinion the best solution is:

JAVA SOLUTION

Create simple interface :

public interface IOnBackPressed {
    /**
     * If you return true the back press will not be taken into account, otherwise the activity will act naturally
     * @return true if your processing has priority if not false
     */
    boolean onBackPressed();
}

And in your Activity

public class MyActivity extends Activity {
    @Override public void onBackPressed() {
    Fragment fragment = getSupportFragmentManager().findFragmentById(R.id.main_container);
       if (!(fragment instanceof IOnBackPressed) || !((IOnBackPressed) fragment).onBackPressed()) {
          super.onBackPressed();
       }
    } ...
}

Finally in your Fragment:

public class MyFragment extends Fragment implements IOnBackPressed{
   @Override
   public boolean onBackPressed() {
       if (myCondition) {
            //action not popBackStack
            return true; 
        } else {
            return false;
        }
    }
}

KOTLIN SOLUTION

1 - Create Interface

interface IOnBackPressed {
    fun onBackPressed(): Boolean
}

2 - Prepare your Activity

class MyActivity : AppCompatActivity() {
    override fun onBackPressed() {
        val fragment =
            this.supportFragmentManager.findFragmentById(R.id.main_container)
        (fragment as? IOnBackPressed)?.onBackPressed()?.not()?.let {
            super.onBackPressed()
        }
    }
}

3 - Implement in your target Fragment

class MyFragment : Fragment(), IOnBackPressed {
    override fun onBackPressed(): Boolean {
        return if (myCondition) {
            //action not popBackStack
            true
        } else {
            false
        }
    }
}

MySQL can index the first x characters of a column,but a TEXT type is of variable length so mysql cant assure the uniqueness of the column.If you still want text column,use VARCHAR.

I guess you are using an old version of hibernate. You can download the latest version, 5.2, from here.

A dictionary can be passed to format(), each key name will become a variable for each associated value.

dict = {'string1': 'go',
        'string2': 'now',
        'string3': 'great'}

multiline_string = '''I'm will {string1} there
I will go {string2}
{string3}'''.format(**dict)

print(multiline_string)

Also a list can be passed to format(), the index number of each value will be used as variables in this case.

list = ['go',
        'now',
        'great']

multiline_string = '''I'm will {0} there
I will go {1}
{2}'''.format(*list)

print(multiline_string)

Both solutions above will output the same:

I'm will go there
I will go now
great

just copy " _CRT_SECURE_NO_WARNINGS " paste it on projects->properties->c/c++->preprocessor->preprocessor definitions click ok.it will work

CONCAT, as stated, is not supported prior to SQL Server 2012. However you can concatenate simply using the + operator as suggested. But beware, this operator will throw an error if the first operand is a number since it thinks will be adding and not concatenating. To resolve this issue just add '' in front. For example

someNumber + 'someString' + .... + lastVariableToConcatenate

will raise an error BUT '' + someNumber + 'someString' + ...... will work just fine.

Also, if there are two numbers to be concatenated make sure you add a '' between them, like so

.... + someNumber + '' + someOtherNumber + .....

The answer is already in the comments of the question. For more visibility, I am copying this solution here:

.not-active {_x000D_
  pointer-events: none;_x000D_
  cursor: default;_x000D_
  text-decoration: none;_x000D_
  color: black;_x000D_
}

<a href="link.html" class="not-active">Link</a>

For browser support, please see https://caniuse.com/#feat=pointer-events. If you need to support IE there is a workaround; see this answer.

Warning: The use of pointer-events in CSS for non-SVG elements is experimental. The feature used to be part of the CSS3 UI draft specification but, due to many open issues, has been postponed to CSS4.

you could see this info

for i in /var/run/*;do echo -n "$i "; find $i| wc -l;done | column -t

from datetime import datetime as dt
dt.utcnow().strftime("%s")

If the URL is https, like used for Amazon S3, then use getURL

json <- fromJSON(getURL('https://s3.amazonaws.com/bucket/my.json'))

Using the ToList() extension method is your best option:

someValues.ToList().ForEach(x => list.Add(x + 1));

There is no extension method in the BCL that implements ForEach directly.

Although there's no extension method in the BCL that does this, there is still an option in the System namespace... if you add Reactive Extensions to your project:

using System.Reactive.Linq;

someValues.ToObservable().Subscribe(x => list.Add(x + 1));

This has the same end result as the above use of ToList, but is (in theory) more efficient, because it streams the values directly to the delegate.

Check for "projtemp" and then check if the previous one is a number entry (like 19,18..etc..) if that is so then get the row no of that proj temp ....

and if that is not so ..then re-check that the previous entry is projtemp or a number entry ...

You can also use translate(). If the third argument is too short, the corresponding characters from the second argument are deleted. Unlike regexp_replace() you don't need to worry about special characters. Source code.

Did you write the SyndFeed?

Does sf.getEntries return List or List<SyndEntry>? My guess is it returns List and changing it to return List<SyndEntry> will fix the problem.

If SyndFeed is part of a library, I don't think you can remove the warning without adding the @SuppressWarning("unchecked") annotation to your method.

Umair R's answer is mostly the right move to solve the problem, as this error used to be caused by the missing links between opencv libs and the programme. so there is the need to specify the ld_libraty_path configuration. ps. the usual library path is suppose to be:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

I have tried this and it worked well.

In Python 3.1+ you can specify multiple context expressions, and they will be processed as if multiple with statements were nested:

with A() as a, B() as b:
    suite

is equivalent to

with A() as a:
    with B() as b:
        suite

This also means that you can use the alias from the first expression in the second (useful when working with db connections/cursors):

with get_conn() as conn, conn.cursor() as cursor:
    cursor.execute(sql)

My solution below is in es6 because I made use of const if you prefer es5 you can replace all const with var.

const str = "       Hello World!        ";_x000D_
// const str = "                     ";_x000D_
_x000D_
checkForWhiteSpaces(str);_x000D_
_x000D_
function checkForWhiteSpaces(args) {_x000D_
    const trimmedString = args.trim().length;_x000D_
    console.log(checkStringLength(trimmedString))     _x000D_
    return checkStringLength(trimmedString)        _x000D_
}_x000D_
_x000D_
// If the browser doesn't support the trim function_x000D_
// you can make use of the regular expression below_x000D_
_x000D_
checkForWhiteSpaces2(str);_x000D_
_x000D_
function checkForWhiteSpaces2(args) {_x000D_
    const trimmedString = args.replace(/^\s+|\s+$/gm, '').length;_x000D_
    console.log(checkStringLength(trimmedString))     _x000D_
    return checkStringLength(trimmedString)_x000D_
}_x000D_
_x000D_
function checkStringLength(args) {_x000D_
    return args > 0 ? "not empty" : "empty string";_x000D_
}

select Qty, vajan, Rate,Amt,nhamali,ncommission,ntolai from SalesDtl,SalesMSt where SalesDtl.PurEntryNo=1 and SalesMST.SaleDate=  (22/03/2014) and SalesMST.SaleNo= SalesDtl.SaleNo;

That should work.

    func addBorder(edge: UIRectEdge, color: UIColor, borderWidth: CGFloat) {

        let seperator = UIView()
        self.addSubview(seperator)

        seperator.backgroundColor = color

        if edge == .top || edge == .bottom
        {
            seperator.leadingAnchor.constraint(equalTo: self.leadingAnchor, constant: 0).isActive = true
            seperator.trailingAnchor.constraint(equalTo: self.trailingAnchor, constant: 0).isActive = true
            seperator.heightAnchor.constraint(equalToConstant: borderWidth).isActive = true

            if edge == .top
            {
                seperator.topAnchor.constraint(equalTo: self.topAnchor, constant: 0).isActive = true
            }
            else
            {
                seperator.bottomAnchor.constraint(equalTo: self.bottomAnchor, constant: 0).isActive = true
            }
        }
        else if edge == .left || edge == .right
        {
            seperator.topAnchor.constraint(equalTo: self.topAnchor, constant: 0).isActive = true
            seperator.bottomAnchor.constraint(equalTo: self.bottomAnchor, constant: 0).isActive = true
            seperator.widthAnchor.constraint(equalToConstant: borderWidth).isActive = true

            if edge == .left
            {
                seperator.leadingAnchor.constraint(equalTo: self.leadingAnchor, constant: 0).isActive = true
            }
            else
            {
                seperator.trailingAnchor.constraint(equalTo: self.trailingAnchor, constant: 0).isActive = true
            }
        }
    }

}

Here maybe?

I believe that the code should be:

because root does not have a password. the (using password: YES) is saying "you're using a password with this user"

Although Apple recommends tel: in their docs for Mobile Safari, currently (iOS 4.3) it accepts callto: just the same. So I recommend using callto: on a generic web site as it works with both Skype and iPhone and I expect it will work on Android phones, too.

Update (June 2013)

This is still a matter of deciding what you want your web page to offer. On my websites I provide both tel: and callto: links (the latter labeled as being for Skype) since Desktop browsers on Mac don't do anything with tel: links while mobile Android doesn't do anything with callto: links. Even Google Chrome with the Google Talk plugin does not respond to tel: links. Still, I prefer offering both links on the desktop in case someone has gone to the trouble of getting tel: links to work on their computer.

If the site design dictated that I only provide one link, I'd use a tel: link that I would try to change to callto: on desktop browsers.

Well the answer was sitting right in front of me the whole time.

In SQL Server Management Studio 2008 there is a Debug button in the toolbar. Set a break point in a query window to step through.

I dismissed this functionality at the beginning because I didn't think of stepping INTO the stored procedure, which you can do with ease.

SSMS basically does what FinnNK mentioned with the MSDN walkthrough but automatically.

So easy! Thanks for your help FinnNK.

Edit: I should add a step in there to find the stored procedure call with parameters I used SQL Profiler on my database.

The author of this question mentions that it’s usually only after MySQL prints its output that he realises that the wrong query was executed. As noted, in this case, Ctrl-C doesn’t help. However, I’ve noticed that it will abort the current query – if you catch it before any output is printed. For example:

mysql> select * from jos_users, jos_comprofiler;

MySQL gets busy generating the Cartesian Product of the above two tables and you soon notice that MySQL hasn't printed any output to screen (the process state is Sending data) so you type Ctrl-C:

Ctrl-C -- sending "KILL QUERY 113240" to server ...
Ctrl-C -- query aborted.
ERROR 1317 (70100): Query execution was interrupted

Ctrl-C can similarly be used to stop an UPDATE query.

Try setting the JAVA_LIB variable also.

"A picture is worth a thousand words".

I have a simple example here, it's similar to your case.

string s1 = "abc";
string s2 = s1;
s1 = "def";
Console.WriteLine(s2);
// Output: abc

This is what happened:

• Line 1 and 2: s1 and s2 variables reference to the same "abc" string object.
• Line 3: Because strings are immutable, so the "abc" string object do not modify itself (to "def"), but a new "def" string object is created instead, and then s1 references to it.
• Line 4: s2 still references to "abc" string object, so that's the output.

In my case the reason was since the remote repo artifact (non-central) had dependencies from the Maven Central in the .pom file, and the older version of mvn (older than 3.6.0) was used. So, it tried to check the Maven Central artifacts mentioned in the remote repo's .pom for the specific artifact I've added to my dependencies and faced the Maven Central http access issue behind the scenes (I believe the same as described there: Maven dependencies are failing with a 501 error - that is about using https access to Maven Central by default and prohibiting the http access).

Using more recent Maven (from 3.1 to 3.6.0) made it use https to check Maven Central repo dependencies mentioned in the .pom files of the remote repositories and I no longer face the issue.

If somebody wants to send json data in form-data format just need to declare the variables like this

Postman:

As you see, the description parameter will be in basic json format, result of that:

{ description: { spanish: 'hola', english: 'hello' } }

Converting your value in milliseconds to days is simply (MsValue / 86,400,000)

We can get 1/1/1970 as numeric value by DATE(1970,1,1)

= (MsValueCellReference / 86400000) + DATE(1970,1,1)

Using your value of 1271664970687 and formatting it as dd/mm/yyyy hh:mm:ss gives me a date and time of 19/04/2010 08:16:11

Make sure there's no hidden whitespace at the start of your XML file. Also maybe include encoding="UTF-8" (or 16? No clue) in the node.

Adjusted to allow for daylight saving differences. try this:

  function daysBetween(date1, date2) {

 // adjust diff for for daylight savings
 var hoursToAdjust = Math.abs(date1.getTimezoneOffset() /60) - Math.abs(date2.getTimezoneOffset() /60);
 // apply the tz offset
 date2.addHours(hoursToAdjust); 

    // The number of milliseconds in one day
    var ONE_DAY = 1000 * 60 * 60 * 24

    // Convert both dates to milliseconds
    var date1_ms = date1.getTime()
    var date2_ms = date2.getTime()

    // Calculate the difference in milliseconds
    var difference_ms = Math.abs(date1_ms - date2_ms)

    // Convert back to days and return
    return Math.round(difference_ms/ONE_DAY)

}

// you'll want this addHours function too 

Date.prototype.addHours= function(h){
    this.setHours(this.getHours()+h);
    return this;
}

Yes, when you invoke e.extractAll(foo), Python munges that into extractAll(e, foo).

From http://docs.python.org/tutorial/classes.html

the special thing about methods is that the object is passed as the first argument of the function. In our example, the call x.f() is exactly equivalent to MyClass.f(x). In general, calling a method with a list of n arguments is equivalent to calling the corresponding function with an argument list that is created by inserting the method’s object before the first argument.

Emphasis added.

Building of off an earlier example, I think there is a cleaner way of doing this. Create an index.html file in your project and using Stephen's code from above, just convert it into an HTML doc.

<!DOCTYPE html>
<html>
  <base target="_top">
  <script>
    function onSuccess(url) {
      var a = document.createElement("a"); 
      a.href = url;
      a.target = "_blank";
      window.close = function () {
        window.setTimeout(function() {
          google.script.host.close();
        }, 9);
      };
      if (document.createEvent) {
        var event = document.createEvent("MouseEvents");
        if (navigator.userAgent.toLowerCase().indexOf("firefox") > -1) {
          window.document.body.append(a);
        }                        
        event.initEvent("click", true, true); 
        a.dispatchEvent(event);
      } else {
        a.click();
      }
      close();
    }

    function onFailure(url) {
      var div = document.getElementById('failureContent');
      var link = '<a href="' + url + '" target="_blank">Process</a>';
      div.innerHtml = "Failure to open automatically: " + link;
    }

    google.script.run.withSuccessHandler(onSuccess).withFailureHandler(onFailure).getUrl();
  </script>
  <body>
    <div id="failureContent"></div>
  </body>
  <script>
    google.script.host.setHeight(40);
    google.script.host.setWidth(410);
  </script>
</html>

Then, in your Code.gs script, you can have something like the following,

function getUrl() {
  return 'http://whatever.com';
}

function openUrl() {
  var html = HtmlService.createHtmlOutputFromFile("index");
  html.setWidth(90).setHeight(1);
  var ui = SpreadsheetApp.getUi().showModalDialog(html, "Opening ..." );
}

It was very tedious when I get same problem. When I got this problem, I uninstall my SQL Server 2008 but after installing the SQL Server 2008 again,I got the same problem. I was so tensed plus, I had not gotten any help from any site.

To over come this problem. Simply You Need to go on SQL Server Configuration Manager and then click On Protocols on left panel. If you running Network service just disable 'VIA' Protocol. And after that try to start your SQL service it will run successfully.

That is exactly what you do with an advanced filter. If it's a one shot, you don't even need a macro, it is available in the Data menu.

    CriteriaRange:=Sheets("Sheet1").Range("G1:G2"), CopyToRange:=Range("A1:D1") _

Please add json2.js in your project . i was faced the same issue i have fixed.

please use the link: https://raw.github.com/douglascrockford/JSON-js/master/json2.js and create new file json.js, copy the page and past into newly created file , and move that file into your web application.

I hope it will work.

You can't "directly" mock static method (hence extension method) with mocking framework. You can try Moles (http://research.microsoft.com/en-us/projects/pex/downloads.aspx), a free tool from Microsoft that implements a different approach. Here is the description of the tool:

Moles is a lightweight framework for test stubs and detours in .NET that is based on delegates.

Moles may be used to detour any .NET method, including non-virtual/static methods in sealed types.

You can use Moles with any testing framework (it's independent about that).

In general, that depends on your shell, but if you use bash, zsh, ksh or sh (as provided by dash), the following should work:

if ! type "$foobar_command_name" > /dev/null; then
  # install foobar here
fi

For a real installation script, you'd probably want to be sure that type doesn't return successfully in the case when there is an alias foobar. In bash you could do something like this:

if ! foobar_loc="$(type -p "$foobar_command_name")" || [[ -z $foobar_loc ]]; then
  # install foobar here
fi

According to the documentation:

max(iterable[, key])
max(arg1, arg2, *args[, key])
Return the largest item in an iterable or the largest of two or more arguments.

If one positional argument is provided, iterable must be a non-empty iterable (such as a non-empty string, tuple or list). The largest item in the iterable is returned. If two or more positional arguments are provided, the largest of the positional arguments is returned.

The optional key argument specifies a one-argument ordering function like that used for list.sort(). The key argument, if supplied, must be in keyword form (for example, max(a,b,c,key=func)).

What this is saying is that in your case, you are providing a list, in this case players. Then the max function will iterate over all the items in the list and compare them to each other to get a "maximum".

As you can imagine, with a complex object like a player determining its value for comparison is tricky, so you are given the key argument to determine how the max function will decide the value of each player. In this case, you are using a lambda function to say "for each p in players get p.totalscore and use that as his value for comparison".

The answer above did not work for me (python 3.6, Anaconda, pandas 0.20.3). It worked with

conda install -c anaconda pandas 

Unfortunately I do not know how to help with Eclipse.

Use smaller h

// 24 hrs 
H:i 
// output 14:20

// 12 hrs 
h:i 
// output 2:20

If you're using Linux, open your terminal and type virtualenv halfway and autocomplete with tab key. If there's no auto-completion install virtualenv on your system by running:

mycomp$sudo apt-get install virtualenv
//if you're already super user.
mycomp#apt-get install virtualenv

You can now navigate to where you want to create your project and do:

myprj$pip3 install virtualenv    
//to install python 3.5 and above  
myprj$virtualenv venv --python=python3.5  
//to activate virtualenv  
(venv)myprj$source venv/bin/activate  
(venv)myprj$deactivate

I had more than 100MB data, therefore I could not restore database using Pgadmin4.

I used simply postgres client, and write below command.

postgres@khan:/$ pg_restore -d database_name /home/khan/Downloads/dump.sql

It worked fine and took few seconds.You can see below link for more information. https://www.postgresql.org/docs/8.1/app-pgrestore.html

Try this piece of code:

NSString *digit = [[sender titlelabel] text];
NSLog(@"%@", digit);

The message means that you have incorrect syntax for using the digit variable. If you're not sending it any message - you don't need any brackets.

Its been updated so

root.configure(background="red")

is now:

root.configure(bg="red")

Number 7 on the list is Jackson, not using Jerkson. It has support for Scala objects, (case classes etc).

Below is an example of how I use it.

object MyJacksonMapper extends JacksonMapper
val jsonString = MyJacksonMapper.serializeJson(myObject)
val myNewObject = MyJacksonMapper.deserializeJson[MyCaseClass](jsonString)

This makes it very simple. In addition is the XmlSerializer and support for JAXB Annotations is very handy.

This blog post describes it's use with JAXB Annotations and the Play Framework.

http://krasserm.blogspot.co.uk/2012/02/using-jaxb-for-xml-and-json-apis-in.html

Here is my current JacksonMapper.

trait JacksonMapper {

  def jsonSerializer = {
    val m = new ObjectMapper()
    m.registerModule(DefaultScalaModule)
    m
  }

  def xmlSerializer = {
    val m = new XmlMapper()
    m.registerModule(DefaultScalaModule)
    m
  }

  def deserializeJson[T: Manifest](value: String): T = jsonSerializer.readValue(value, typeReference[T])
  def serializeJson(value: Any) = jsonSerializer.writerWithDefaultPrettyPrinter().writeValueAsString(value)
  def deserializeXml[T: Manifest](value: String): T = xmlSerializer.readValue(value, typeReference[T])
  def serializeXml(value: Any) = xmlSerializer.writeValueAsString(value)

  private[this] def typeReference[T: Manifest] = new TypeReference[T] {
    override def getType = typeFromManifest(manifest[T])
  }

  private[this] def typeFromManifest(m: Manifest[_]): Type = {
     if (m.typeArguments.isEmpty) { m.erasure }
     else new ParameterizedType {
       def getRawType = m.erasure

       def getActualTypeArguments = m.typeArguments.map(typeFromManifest).toArray

       def getOwnerType = null
     }
  }
}   

The most upvoted answer above is weird in a way that it simply clears the Clipboard and then gets the content (which is then empty). One could clear the clipboard to be sure that some clipboard content type like "formated text" does not "cover" your plain text content you want to save in the clipboard.

The following piece of code replaces all newlines in the clipboard by spaces, then removes all double spaces and finally saves the content back to the clipboard:

import win32clipboard

win32clipboard.OpenClipboard()
c = win32clipboard.GetClipboardData()
win32clipboard.EmptyClipboard()
c = c.replace('\n', ' ')
c = c.replace('\r', ' ')
while c.find('  ') != -1:
    c = c.replace('  ', ' ')
win32clipboard.SetClipboardText(c)
win32clipboard.CloseClipboard()

Depending on the nature of the duplicate rows, it looks like all you want is to have case-sensitivity on those columns. Setting the collation on these columns should be what you're after:

SELECT DISTINCT p.IDNO COLLATE SQL_Latin1_General_CP1_CI_AS, p.FirstName COLLATE SQL_Latin1_General_CP1_CI_AS, p.LastName COLLATE SQL_Latin1_General_CP1_CI_AS
FROM people P

very simple example of parallel processing is

from multiprocessing import Process

output1 = list()
output2 = list()
output3 = list()

def yourfunction():
    for j in range(0, 10):
        # calc individual parameter value
        parameter = j * offset
        # call the calculation
        out1, out2, out3 = calc_stuff(parameter=parameter)

        # put results into correct output list
        output1.append(out1)
        output2.append(out2)
        output3.append(out3)

if __name__ == '__main__':
    p = Process(target=pa.yourfunction, args=('bob',))
    p.start()
    p.join()

Two things you can do:

git checkout -b sillyname
git commit -am "silly message"
git checkout - 

or

git stash -u
git branch sillyname stash@{0}

(git checkout - <-- the dash is a shortcut for the previous branch you were on )

(git stash -u <-- the -u means that it also takes unstaged changes )

Use yourLabel.textAlignment = NSTextAlignmentCenter; for iOS >= 6.0 and yourLabel.textAlignment = UITextAlignmentCenter; for iOS < 6.0.

Apparently the change event is not fired if a selection already exists when using data. I ended up updating the data manually on select to resolve the problem.

$("#search_code").on("select2-selecting", function(e) {
    $("#search_code").select2("data",e.choice);
});

I know this is pretty late but hopefully this answer will save others time.

1. Add the required key here like this. In this case its SecureCookies:

2. In startup.cs, add the constructor

    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;
   
    }
    public IConfiguration Configuration { get; }
   

3. Access the settings using Configuration["SecureCookies"]

I had the same problem you had. I used a for loop with the sorted function passing in the dictionary like so:

for item in sorted(mydict):
    print(item)

You need to enter the width % for each cell. But wait, there's a better way to do that, it's called CSS:

<style>
     .equalDivide tr td { width:25%; }
</style>

<table class="equalDivide" cellpadding="0" cellspacing="0" width="100%" border="0">
   <tr>
      <td></td>
      <td></td>
      <td></td>
      <td></td>
   </tr>
</table>

No, there is no better way.

Actually you have an error in your pattern. What you want is:

DecimalFormat df = new DecimalFormat("#.00"); 

Note the "00", meaning exactly two decimal places.

If you use "#.##" (# means "optional" digit), it will drop trailing zeroes - ie new DecimalFormat("#.##").format(3.0d); prints just "3", not "3.00".

In Xcode-11.2.1

You might be see different pattern for uploading IPA
Steps:-

i) Add your apple developer id in xcode preference -> account

ii)Clean Build Folder :-

iii) Archive

iv) Tap on Distribute App

v) Choose Ad-hoc to distribute on designated device

6)Tricky part -> User can download app from company's website URL. Many of us might get stuck and start creating website url to upload ipa, which is not required. Simply write google website url with https. :)

7)Click on export and you get ipa.

8)Visit https://www.diawi.com/ & drag and drop ipa you have downloaded. & share the link to your client/user who want to test :)

FIND_IN_SET is your friend in this case

select * from shirts where FIND_IN_SET(1,colors) 

You should always use audio/mpeg, because firefox cannot play audio/mpeg3 files

You need to stringify the json, not calling toString

var buf = Buffer.from(JSON.stringify(obj));

And for converting string to json obj :

var temp = JSON.parse(buf.toString());

In the OnCreate method add this:

if (getSupportActionBar() != null)
    {
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    }

Then add this method:

@Override
public boolean onSupportNavigateUp() {
    onBackPressed();
    return true;
}

Check out Utf8Checker it is simple class that does exactly this in pure managed code. http://utf8checker.codeplex.com

Notice: as already pointed out "determine encoding" makes sense only for byte streams. If you have a string it is already encoded from someone along the way who already knew or guessed the encoding to get the string in the first place.

Here's the basic approach,

DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");

Date beginDate = dateFormat.parse("2013-11-29");
Date endDate = dateFormat.parse("2013-12-4");

Calendar beginCalendar = Calendar.getInstance();
beginCalendar.setTime(beginDate);

Calendar endCalendar = Calendar.getInstance();
endCalendar.setTime(endDate);

There is simple way to implement it. We can use Calendar.add method with loop. The minus days between beginDate and endDate, and the implemented code as below,

int minusDays = 0;
while (true) {
  minusDays++;

  // Day increasing by 1
  beginCalendar.add(Calendar.DAY_OF_MONTH, 1);

  if (dateFormat.format(beginCalendar.getTime()).
            equals(dateFormat.format(endCalendar).getTime())) {
    break;
  }
}
System.out.println("The subtraction between two days is " + (minusDays + 1));**

Explanation

It's worth noting that your code does insert a space

h2::after {
  content: " ";
}

However, it's immediately removed.

From Anonymous inline boxes,

White space content that would subsequently be collapsed away according to the 'white-space' property does not generate any anonymous inline boxes.

And from The 'white-space' processing model,

If a space (U+0020) at the end of a line has 'white-space' set to 'normal', 'nowrap', or 'pre-line', it is also removed.

Solution

So if you don't want the space to be removed, set white-space to pre or pre-wrap.

h2 {_x000D_
  text-decoration: underline;_x000D_
}_x000D_
h2.space::after {_x000D_
  content: " ";_x000D_
  white-space: pre;_x000D_
}

<h2>I don't have space:</h2>_x000D_
<h2 class="space">I have space:</h2>

Do not use non-breaking spaces (U+00a0). They are supposed to prevent line breaks between words. They are not supposed to be used as non-collapsible space, that wouldn't be semantic.

It’s easy; just do the following:

rvm implode

or

rm -rf ~/.rvm

And don’t forget to remove the script calls in the following files:

• ~/.bashrc
• ~/.bash_profile
• ~/.profile

And maybe others depending on whatever shell you’re using.

Use java.io.File.listFiles
Or
If you want to filter the list prior to iteration (or any more complicated use case), use apache-commons FileUtils. FileUtils.listFiles

It's getElementsByName() and getElementsByTagName() - note the "s" in "Elements", indicating that both functions return a list of elements, i.e., a NodeList, which you will access like an array. Note that the second function ends with "TagName" not "Tag".

Even if the function only returns one element it will still be in a NodeList of length one. So:

var els = document.getElementsByName('frmMain');
// els.length will be the number of elements returned
// els[0] will be the first element returned
// els[1] the second, etc.

Assuming your form is the first (or only) form on the page you can do this:

document.getElementsByName('frmMain')[0].elements
document.getElementsByTagName('table')[0].elements

It seems that your best bet is to redefine the java user.name variable either at your command line, or using the eclipse.ini file in your eclipse install root directory.

Here's a new one: https://web.archive.org/web/20111225025454/http://morlhon.net:80/blog/2005/09/07/eclipse-username/

I ran into this issue while working on something at work (using React). Basically, we have some external html content that we save into our document table in the database and then insert onto the page under certain circumstances when you're in the Documents dataset.

So, given n inlines, of which up to n could contain external html, we needed to devise a system to automatically resize the iframe of each inline once the content fully loaded in each. After spinning my wheels for a bit, this is how I ended up doing it:

1. Set a message event listener in the index of our React app which checks for a a specific key that we will set from the sender iframe.
2. In the component that actually renders the iframes, after inserting the external html into it, I append a <script> tag that will wait for the iframe's window.onload to fire. Once that fires, we use postMessage to send a message to the parent window with information about the iframe id, computed height, etc.
3. If the origin matches and the key is satisfied in the index listener, grab the DOM id of the iframe that we pass in the MessageEvent object
4. Once we have the iframe, just set the height from the value that is passed from the iframe postMessage.

// index
if (window.postMessage) {
    window.addEventListener("message", (messageEvent) => {
        if (
            messageEvent.data.origin &&
            messageEvent.data.origin === "company-name-iframe"
        ) {
            const iframe = document.getElementById(messageEvent.data.id)
            // this is the only way to ensure that the height of the iframe container matches its body height
            iframe.style.height = `${messageEvent.data.height}px`
            // by default, the iframe will not expand to fill the width of its parent
            iframe.style.width = "100%"
            // the iframe should take precedence over all pointer events of its immediate parent
            // (you can still click around the iframe to segue, for example, but all content of the iframe
            // will act like it has been directly inserted into the DOM)
            iframe.style.pointerEvents = "all"
            // by default, iframes have an ugly web-1.0 border
            iframe.style.border = "none"
        }
    })
}

// in component that renders n iframes
<iframe
    id={`${props.id}-iframe`}
    src={(() => {
        const html = [`data:text/html,${encodeURIComponent(props.thirdLineData)}`]
        if (window.parent.postMessage) {
            html.push(
                `
                <script>
                window.onload = function(event) {
                    window.parent.postMessage(
                        {
                            height: document.body.scrollHeight,
                            id: "${props.id}-iframe",
                            origin: "company-name-iframe",
                        },
                        "${window.location.origin}"
                    );
                };
                </script>
                `
            )
        }

        return html.join("\n")
    })()}
    onLoad={(event) => {
        // if the browser does not enforce a cross-origin policy,
        // then just access the height directly instead
        try {
            const { target } = event
            const contentDocument = (
                target.contentDocument ||
                // Earlier versions of IE or IE8+ where !DOCTYPE is not specified
                target.contentWindow.document
            )
            if (contentDocument) {
                target.style.height = `${contentDocument.body.scrollHeight}px`
            }
        } catch (error) {
            const expectedError = (
                `Blocked a frame with origin "${window.location.origin}" ` +
                `from accessing a cross-origin frame.`
            )
            if (error.message !== expectedError) {
                /* eslint-disable no-console */
                console.err(
                    `An error (${error.message}) ocurred while trying to check to see ` +
                    "if the inner iframe is accessible or not depending " +
                    "on the browser cross-origin policy"
                )
            }
        }
    }}
/>

You can also look into pandas.Timestamp, which includes methods like .now and .today. Unlike pandas.to_datetime('now'), pandas.Timestamp.now() won't default to UTC:

  import pandas as pd

  pd.Timestamp.now() # will return California time
  # Timestamp('2018-12-19 09:17:07.693648')

  pd.to_datetime('now') # will return UTC time
  # Timestamp('2018-12-19 17:17:08')

This is a highly inefficient way of doing it. You can use the merge statement and then there's no need for cursors, looping or (if you can do without) PL/SQL.

MERGE INTO studLoad l
USING ( SELECT studId, studName FROM student ) s
ON (l.studId = s.studId)
WHEN MATCHED THEN
  UPDATE SET l.studName = s.studName
   WHERE l.studName != s.studName
WHEN NOT MATCHED THEN 
INSERT (l.studID, l.studName)
VALUES (s.studId, s.studName)

Make sure you commit, once completed, in order to be able to see this in the database.

To actually answer your question I would do it something like as follows. This has the benefit of doing most of the work in SQL and only updating based on the rowid, a unique address in the table.

It declares a type, which you place the data within in bulk, 10,000 rows at a time. Then processes these rows individually.

However, as I say this will not be as efficient as merge.

declare

   cursor c_data is
    select b.rowid as rid, a.studId, a.studName
      from student a
      left outer join studLoad b
        on a.studId = b.studId
       and a.studName <> b.studName
           ;

   type t__data is table of c_data%rowtype index by binary_integer;
   t_data t__data;

begin

   open c_data;
   loop
      fetch c_data bulk collect into t_data limit 10000;

      exit when t_data.count = 0;

      for idx in t_data.first .. t_data.last loop
         if t_data(idx).rid is null then
            insert into studLoad (studId, studName)
            values (t_data(idx).studId, t_data(idx).studName);
         else
            update studLoad
               set studName = t_data(idx).studName
             where rowid = t_data(idx).rid
                   ;
         end if;
      end loop;

   end loop;
   close c_data;

end;

The standard exceptions can be constructed from a std::string:

#include <stdexcept>

char const * configfile = "hardcode.cfg";
std::string const anotherfile = get_file();

throw std::runtime_error(std::string("Failed: ") + configfile);
throw std::runtime_error("Error: " + anotherfile);

Note that the base class std::exception can not be constructed thus; you have to use one of the concrete, derived classes.

And about timing:

fn1 <- function (N) {
    for(i in as.numeric(1:N)) { y <- i*i }
}
fn2 <- function (N) {
    i=1
    while (i <= N) {
        y <- i*i
        i <- i + 1
    }
}

system.time(fn1(60000))
# user  system elapsed 
# 0.06    0.00    0.07 
system.time(fn2(60000))
# user  system elapsed 
# 0.12    0.00    0.13

And now we know that for-loop is faster than while-loop. You cannot ignore warnings during timing.

If you just wanted to check whether flash is enabled, this should be enough.

function testFlash() {

    var support = false;

    //IE only
    if("ActiveXObject" in window) {

        try{
            support = !!(new ActiveXObject("ShockwaveFlash.ShockwaveFlash"));
        }catch(e){
            support = false;
        }

    //W3C, better support in legacy browser
    } else {

        support = !!navigator.mimeTypes['application/x-shockwave-flash'];

    }

    return support;

}

Note: avoid checking enabledPlugin, some mobile browser has tap-to-enable flash plugin, and will trigger false negative.

JavaScript is a client-side language and your MySQL database is going to be running on a server.

So you have to rename your file to index.php for example (.php is important) so you can use php code for that. It is not very difficult, but not directly possible with html.

(Somehow you can tell your server to let the html files behave like php files, but this is not the best solution.)

So after you renamed your file, go to the very top, before <html> or <!DOCTYPE html> and type:

<?php
    if($_SERVER['REQUEST_METHOD'] == 'POST') {
        /*Creating variables*/
        $name = $_POST["name"];
        $address = $_POST["address"];
        $age = $_POST["age"];


        $dbhost = "localhost"; /*most of the time it's localhost*/
        $username = "yourusername";
        $password = "yourpassword";
        $dbname = "mydatabase";

        $mysql = mysqli_connect($dbhost, $username, $password, $dbname); //It connects
        $query = "INSERT INTO yourtable (name,address,age) VALUES $name, $address, $age";
        mysqli_query($mysql, $query);
    }
?>
<!DOCTYPE html>
<html>
<head>.......
....
    <form method="post">
        <input name="name" type="text"/>
        <input name="address" type="text"/>
        <input name="age" type="text"/>
    </form>
....

If you have no concrete implementations of the class and the methods aren't static whats the point of testing them? If you have a concrete class then you'll be testing those methods as part of the concrete class's public API.

I know what you are thinking "I don't want to test these methods over and over thats the reason I created the abstract class", but my counter argument to that is that the point of unit tests is to allow developers to make changes, run the tests, and analyze the results. Part of those changes could include overriding your abstract class's methods, both protected and public, which could result in fundamental behavioral changes. Depending on the nature of those changes it could affect how your application runs in unexpected, possibly negative ways. If you have a good unit testing suite problems arising from these types changes should be apparent at development time.

This works for me using git 2.21.0 - it deletes local tracking branches which are merged into HEAD where I have previously --set-upstream on push (I use push.default=upstream because it works best with multiple remotes) and that upstream branch has since been deleted by a fetch --prune (or implicitly if fetch.prune=true in git config):

git branch -vv --merged | grep ': gone]' | awk '{print $1}' | xargs git branch -d

The use of --merged and -d make this a very 'safe' delete. A more aggressive version could drop the --merged and use -D

Assembly assembly = Assembly.LoadFrom("MyAssembly.dll");

Type type = assembly.GetType("MyType");

dynamic instanceOfMyType = Activator.CreateInstance(type);

So in this way you can use functions not with getting methodinfo,and then invoking it.You will do like this instanceOfMyType.MethodName(); But you can't use Intellisense because dynamic types are typed in runtime,not in compile time.

You shouldn't really worry about undefined being renamed. If someone renames undefined, you will be in a lot more trouble than just a few if checks failing. If you really want to protect your code, wrap it in an IFFE (immediately invoked function expression) like this:

(function($, Backbone, _, undefined) {
    //undefined is undefined here.
})(jQuery, Backbone, _);

If you're working with global variables (which is wrong already) in a browser enviroment, I'd check for undefined like this:

if(window.neverDefined === undefined) {
    //Code works
}

Since global variables are a part of the window object, you can simply check against undefined instead of casting to a string and comparing strings.

On top of that, why are your variables not defined? I've seen a lot of code where they check a variables existence and perform some action based on that. Not once have I seen where this approach has been correct.

By example:

# select distinct code from Platform where id in ( select platform__id from Build where product=p)
pl_ids = Build.objects.values('platform__id').filter(product=p)
platforms = Platform.objects.values_list('code', flat=True).filter(id__in=pl_ids).distinct('code')
platforms = list(platforms) if platforms else []

Classification – Predicts categorical class labels – Classifies data (constructs a model) based on a training set and the values (class labels) in a class label attribute – Uses the model in classifying new data

Cluster: a collection of data objects – Similar to one another within the same cluster – Dissimilar to the objects in other clusters

Based on this page:

• Run regedit (remember to run it as the administrator)
• Expand HKEY_LOCAL_MACHINE
• Expand SOFTWARE
• Expand Microsoft
• Expand Windows
• Expand CurrentVersion
• Expand App Paths
• At App Paths, add a new KEY called sqldeveloper.exe
• Expand sqldeveloper.exe
• Modify the (DEFAULT) value to the full pathway to the sqldeveloper executable (See example below step 11)
• Create a new STRING VALUE called PATH and set it value to the sqldeveloper pathway + \jdk\jre\bin

i know this question is old, but hopefully it will help someone. i found a great plugin for those who are using PyCharm IDE: string-manipulation that can easily escape double quotes (and many more...), this plugin is great for cases where you know what the string going to be. for other cases, using json.dumps(string) will be the recommended solution

str_to_escape = 'my string with "double quotes" blablabla'

after_escape = 'my string with \"double quotes\" blablabla'

We can use [(ngModel)] in following way and have a value selection variable radioSelected

Example tutorial

Demo Link

app.component.html

  <div class="text-center mt-5">
  <h4>Selected value is {{radioSel.name}}</h4>

  <div>
    <ul class="list-group">
          <li class="list-group-item"  *ngFor="let item of itemsList">
            <input type="radio" [(ngModel)]="radioSelected" name="list_name" value="{{item.value}}" (change)="onItemChange(item)"/> 
            {{item.name}}

          </li>
    </ul>
  </div>


  <h5>{{radioSelectedString}}</h5>

  </div>

app.component.ts

  import {Item} from '../app/item';
  import {ITEMS} from '../app/mock-data';

  @Component({
    selector: 'app-root',
    templateUrl: './app.component.html',
    styleUrls: ['./app.component.css']
  })
  export class AppComponent {
    title = 'app';
    radioSel:any;
    radioSelected:string;
    radioSelectedString:string;
    itemsList: Item[] = ITEMS;


      constructor() {
        this.itemsList = ITEMS;
        //Selecting Default Radio item here
        this.radioSelected = "item_3";
        this.getSelecteditem();
      }

      // Get row item from array  
      getSelecteditem(){
        this.radioSel = ITEMS.find(Item => Item.value === this.radioSelected);
        this.radioSelectedString = JSON.stringify(this.radioSel);
      }
      // Radio Change Event
      onItemChange(item){
        this.getSelecteditem();
      }

  }

Sample Data for Listing

        export const ITEMS: Item[] = [
            {
                name:'Item 1',
                value:'item_1'
            },
            {
                name:'Item 2',
                value:'item_2'
            },
            {
                name:'Item 3',
                value:'item_3'
            },
            {
                name:'Item 4',
                value:'item_4'
                },
                {
                    name:'Item 5',
                    value:'item_5'
                }
        ];

If table cols and values are variables then there are two ways:

With double quotes "" the complete query:

$query = "INSERT INTO $table_name (id, $col1, $col2)
                 VALUES (NULL, '$val1', '$val2')";

Or

 $query = "INSERT INTO ".$table_name." (id, ".$col1.", ".$col2.")
               VALUES (NULL, '".$val1."', '".$val2."')";

With single quotes '':

$query = 'INSERT INTO '.$table_name.' (id, '.$col1.', '.$col2.')
             VALUES (NULL, '.$val1.', '.$val2.')';

Use back ticks `` when a column/value name is similar to a MySQL reserved keyword.

Note: If you are denoting a column name with a table name then use back ticks like this:

`table_name`. `column_name` <-- Note: exclude . from back ticks.

For a realistic approach that emulates the most human behavior, you may want to add a referer in your curl options. You may also want to add a follow_location to your curl options. Trust me, whoever said that cURLING Google results is impossible, is a complete dolt and should throw his/her computer against the wall in hopes of never returning to the internetz again. Everything that you can do "IRL" with your own browser can all be emulated using PHP cURL or libCURL in Python. You just need to do more cURLS to get buff. Then you will see what I mean. :)

  $url = "http://www.google.com/search?q=".$strSearch."&hl=en&start=0&sa=N";
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_REFERER, 'http://www.example.com/1');
  curl_setopt($ch, CURLOPT_HEADER, 0);
  curl_setopt($ch, CURLOPT_VERBOSE, 0);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible;)");
  curl_setopt($ch, CURLOPT_URL, urlencode($url));
  $response = curl_exec($ch);
  curl_close($ch);

Another solution is to: (1) copy the whole table - paste as a link in the same spreadsheet, from now on work only on the 'linked table' (2) copy the column with values to be sorted and paste values only just next to the table you want to sort (3) select the table and replace all = with e.g. #, this will change reference in a static text (4) sort the table by the pasted values (5) replace back all # with =, the references are back Done! It goes pretty fast when using excel shortcuts

If you know the array location you can can pass it into itself. If you are removing multiple items I suggest you remove them in reverse order.

#Setup array
array = [55,126,555,2,36]
#Remove 55 which is in position 0
array.remove(array[0])

I was already adding something to the background so , This thing worked for me:

   android:backgroundTint="@android:color/transparent"

(Android Studio 3.4.1)

EDIT: only works on android api level 21 and above. for compatibility, use this instead

   android:background="@android:color/transparent"

Here is how you do in Eloquent

$users = User::whereIn('id', array(1, 2, 3))->get();

And if you are using Query builder then :

$users = DB::table('users')->whereIn('id', array(1, 2, 3))->get();

This one returns time like youtube videos

    function getYoutubeLikeToDisplay(millisec) {
        var seconds = (millisec / 1000).toFixed(0);
        var minutes = Math.floor(seconds / 60);
        var hours = "";
        if (minutes > 59) {
            hours = Math.floor(minutes / 60);
            hours = (hours >= 10) ? hours : "0" + hours;
            minutes = minutes - (hours * 60);
            minutes = (minutes >= 10) ? minutes : "0" + minutes;
        }

        seconds = Math.floor(seconds % 60);
        seconds = (seconds >= 10) ? seconds : "0" + seconds;
        if (hours != "") {
            return hours + ":" + minutes + ":" + seconds;
        }
        return minutes + ":" + seconds;
    }

Output:

• getYoutubeLikeToDisplay(129900) = "2:10"
• getYoutubeLikeToDisplay(1229900) = "20:30"
• getYoutubeLikeToDisplay(21229900) = "05:53:50"

This is similar to aSeptik's answer, but what about this approach? Wrap the CSS code which you want to disable using JavaScript in <noscript> tags. That way if javaScript is off, the CSS :hover will be used, otherwise the JavaScript effect will be used.

Example:

<noscript>
<style type="text/css">
ul#mainFilter a:hover {
  /* some CSS attributes here */
}
</style>
</noscript>
<script type="text/javascript">
$("ul#mainFilter a").hover(
     function(o){ /* ...do your stuff... */ }, 
     function(o){ /* ...do your stuff... */ });
</script>

You can solve your problem with help of Attribute routing

Controller

[Route("api/category/{categoryId}")]
public IEnumerable<Order> GetCategoryId(int categoryId) { ... }

URI in jquery

api/category/1

Route Configuration

using System.Web.Http;

namespace WebApplication
{
    public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            // Web API routes
            config.MapHttpAttributeRoutes();

            // Other Web API configuration not shown.
        }
    }
}

and your default routing is working as default convention-based routing

Controller

public string Get(int id)
    {
        return "object of id id";
    }   

URI in Jquery

/api/records/1 

Route Configuration

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        // Attribute routing.
        config.MapHttpAttributeRoutes();

        // Convention-based routing.
        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );
    }
}

I guess using break to your teacher is like breaking a branch of tree to get the fruit,use some other tricks (bow the branch) so that you get the fruit and the branch is still alive.:)

Just in case someone is looking to this too. In .net core 3+ most of this is obsolete. The update way is:

public void Configure(
    IApplicationBuilder app,
    IWebHostEnvironment env,
    ILogger<Startup> logger)
{
    if (env.EnvironmentName == Environments.Development)
    {
        // logger.LogInformation("In Development environment");
    }
}

How to execute Python scripts in Windows?

You could install pylauncher. It is used to launch .py, .pyw, .pyc, .pyo files and supports multiple Python installations:

T\:> blah.py argument

You can run your Python script without specifying .py extension if you have .py, .pyw in PATHEXT environment variable:

T:\> blah argument

It adds support for shebang (#! header line) to select desired Python version on Windows if you have multiple versions installed. You could use *nix-compatible syntax #! /usr/bin/env python.

You can specify version explicitly e.g., to run using the latest installed Python 3 version:

T:\> py -3 blah.py argument

It should also fix your sys.argv issue as a side-effect.

For me (react-router v4, react v16) the problem was that I had the navigation component all right:

import { Link, withRouter } from 'react-router-dom'

class MainMenu extends Component {

  render() {
    return (
            ...
            <NavLink to="/contact">Contact</NavLink>
            ...
    );
  }
}

export default withRouter(MainMenu);

Both using either

to="/contact" 

or

OnClick={() => this.props.history.push('/contact')}; 

The behavior was still the same - the URL in browser changed but wrong components were rendered, the router was called with the same old URL.

The culprit was in the router definition. I had to move the MainMenu component as a child of the Router component!

// wrong placement of the component that calls the router
<MainMenu history={this.props.history} />
<Router>
   <div>
     // this is the right place for the component!
     <MainMenu history={this.props.history} />
     <Route path="/" exact component={MainPage} />
     <Route path="/contact/" component={MainPage} />
   </div>
</Router>

I'd stay with two different interfaces.

You said that 'I want to group my service executors under a common interface... It also seems overkill creating two separate interfaces for the two different service calls... A class will only implement one of these interfaces'

It's not clear what is the reason to have a single interface then. If you want to use it as a marker, you can just exploit annotations instead.

Another point is that there is a possible case that your requirements change and method(s) with another signature appears at the interface. Of course it's possible to use Adapter pattern then but it would be rather strange to see that particular class implements interface with, say, three methods where two of them trow UnsupportedOperationException. It's possible that the forth method appears etc.

Just as a note you can also use this for iPads:

activityViewController.popoverPresentationController?.sourceView = sender

So the popover pops from the sender (the button in that case).

Performance wise there is no point to keep non clustered indexes during this as they will get re-updated on drop and create. If it is a big data set you should consider renaming the table (if possible , any security settings on it?), re-creating an empty table with the correct keys migrate all data there. You have to make sure you have enough space for this.

The characters you are reading on your screen now each have a numerical value. In the ASCII format, for example, the letter 'A' is 65, 'B' is 66, and so on. If you look at a table of characters available in ASCII you will see that it isn't much use for someone who wishes to write something in Mandarin, Arabic, or Japanese. For characters / words from those languages to be displayed we needed another system of encoding them to and from numbers stored in computer memory.

UTF-8 is just one of the encoding methods that were invented to implement this requirement. It lets you write text in all kinds of languages, so French accents will appear perfectly fine, as will text like this

???? ????? (Bzia zbasa), ???????, Ç'kemi, ???, and even right-to-left writing such as this ?????? ?????

If you copy and paste the above text into notepad and then try to save the file as ANSI (another format) you will receive a warning that saving in this format will lose some of the formatting. Accept it, then re-load the text file and you'll see something like this

???? ????? (Bzia zbasa), ???????, Ç'kemi, ???, and even right-to-left writing such as this ?????? ?????

You must enable the library GD2.

Find your (proper) php.ini file

Find the line: ;extension=php_gd2.dll and remove the semicolon in the front.

The line should look like this:

extension=php_gd2.dll

Then restart apache and you should be good to go.

As long as the User does not delete their cookies or close their browser, the session should stay in existence.

REQUEST:

 $.ajax({
            url: "http://localhost:8079/students/add/",
            type: "POST",

            data: JSON.stringify(somejson),
            dataType: "json",
            success: function (response) {
                var resp = JSON.parse(response)
                alert(resp.status);
            },
            error: function (xhr, status) {
                alert("error");
            }
        });

RESPONSE:

response = HttpResponse(json.dumps('{"status" : "success"}'))
response.__setitem__("Content-type", "application/json")
response.__setitem__("Access-Control-Allow-Origin", "*")

return response

I usually use the Export/import tables feature of IntelliJ DataGrip.

To get Sunday as 1 through Saturday as 7, this is the simplest solution to your question:

datetime.date.today().toordinal()%7 + 1

All of them:

import datetime

today = datetime.date.today()
sunday = today - datetime.timedelta(today.weekday()+1)

for i in range(7):
    tmp_date = sunday + datetime.timedelta(i)
    print tmp_date.toordinal()%7 + 1, '==', tmp_date.strftime('%A')

Output:

1 == Sunday
2 == Monday
3 == Tuesday
4 == Wednesday
5 == Thursday
6 == Friday
7 == Saturday

I use these easy functions, it work like jquery slideUp slideDown, use it in an helper class, just pass your view :

public static void expand(final View v) {
    v.measure(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.WRAP_CONTENT);
    final int targetHeight = v.getMeasuredHeight();

    // Older versions of android (pre API 21) cancel animations for views with a height of 0.
    v.getLayoutParams().height = 1;
    v.setVisibility(View.VISIBLE);
    Animation a = new Animation()
    {
        @Override
        protected void applyTransformation(float interpolatedTime, Transformation t) {
            v.getLayoutParams().height = interpolatedTime == 1
                    ? WindowManager.LayoutParams.WRAP_CONTENT
                    : (int)(targetHeight * interpolatedTime);
            v.requestLayout();
        }

        @Override
        public boolean willChangeBounds() {
            return true;
        }
    };

    // 1dp/ms
    a.setDuration((int) (targetHeight / v.getContext().getResources().getDisplayMetrics().density));
    v.startAnimation(a);
}

public static void collapse(final View v) {
    final int initialHeight = v.getMeasuredHeight();

    Animation a = new Animation()
    {
        @Override
        protected void applyTransformation(float interpolatedTime, Transformation t) {
            if(interpolatedTime == 1){
                v.setVisibility(View.GONE);
            }else{
                v.getLayoutParams().height = initialHeight - (int)(initialHeight * interpolatedTime);
                v.requestLayout();
            }
        }

        @Override
        public boolean willChangeBounds() {
            return true;
        }
    };

    // 1dp/ms
    a.setDuration((int)(initialHeight / v.getContext().getResources().getDisplayMetrics().density));
    v.startAnimation(a);
}

If you want to check if a string contains substring or not using regex, the closest you can do is by using find() -

    private static final validPattern =   "\\bstores\\b.*\\bstore\\b.*\\bproduct\\b"
    Pattern pattern = Pattern.compile(validPattern);
    Matcher matcher = pattern.matcher(inputString);
    System.out.print(matcher.find()); // should print true or false.

Note the difference between matches() and find(), matches() return true if the whole string matches the given pattern. find() tries to find a substring that matches the pattern in a given input string. Also by using find() you don't have to add extra matching like - (?s).* at the beginning and .* at the end of your regex pattern.

There is a bug in robocopy in interpreting the source name. If you include a back slash at the end of the path to describe a folder it keeps including the string for the source into the rest of the line. ie

robocopy "C:\back up\" %destination% /e Nothing here will go to the destination string

robocopy "C:\back up" %destination% /e but this works

I may be wrong but I think both should work!

Here is a code I came Up with:

import React, {Component} from "react";
import './header.css'

export default class Header extends Component{
    state = {
        active : false
    };


    toggleMenuSwitch = () => {
        this.setState((state)=>{
            return{
                active: !state.active
            }
        })
    };
    render() {
        //destructuring
        const {active} = this.state;

        let className = 'toggle__sidebar';

        if(active){
            className += ' active';
        }

        return(
            <header className="header">
                <div className="header__wrapper">
                    <div className="header__cell header__cell--logo opened">
                        <a href="#" className="logo">
                            <img src="https://www.nrgcrm.olezzek.id.lv/images/logo.svg" alt=""/>
                        </a>
                        <a href="#" className={className}
                           onClick={ this.toggleMenuSwitch }
                           data-toggle="sidebar">
                            <i></i>
                        </a>
                    </div>
                    <div className="header__cell">

                    </div>
                </div>
            </header>
        );
    };

Real-Time Object-Oriented Modeling was fantastic (published in 1994 and now selling for as little as 81 cents, plus $3.99 shipping).

This is a sample example you can try this,

var _pageNumber = 2,
  _pageSize = 50;

Student.count({},function(err,count){
  Student.find({}, null, {
    sort: {
      Name: 1
    }
  }).skip(_pageNumber > 0 ? ((_pageNumber - 1) * _pageSize) : 0).limit(_pageSize).exec(function(err, docs) {
    if (err)
      res.json(err);
    else
      res.json({
        "TotalCount": count,
        "_Array": docs
      });
  });
 });

You are passing wrong mode to you view. Your view is looking for @model IEnumerable<Standings.Models.Teams> and you are passing var model = tm.Name.ToList(); name list. You have to pass list of Teams.

You have to pass following model

var model = new List<Teams>();

model.Add(new Teams { Name =  new List<string>(){"Sky","ABC"}});
model.Add(new Teams { Name =  new List<string>(){"John","XYZ"} });
return View(model);

The DataGrid has an XAML property IsReadOnly that you can set to true:

<my:DataGrid
    IsReadOnly="True"

I'd like to add a new version of flatten case (this is what i needed :)) which, according to my probes with the above jsFiddler, is slightly faster then the currently selected one. Moreover, me personally see this snippet a bit more readable, which is of course important for multi-developer projects.

function flattenObject(graph) {
    let result = {},
        item,
        key;

    function recurr(graph, path) {
        if (Array.isArray(graph)) {
            graph.forEach(function (itm, idx) {
                key = path + '[' + idx + ']';
                if (itm && typeof itm === 'object') {
                    recurr(itm, key);
                } else {
                    result[key] = itm;
                }
            });
        } else {
            Reflect.ownKeys(graph).forEach(function (p) {
                key = path + '.' + p;
                item = graph[p];
                if (item && typeof item === 'object') {
                    recurr(item, key);
                } else {
                    result[key] = item;
                }
            });
        }
    }
    recurr(graph, '');

    return result;
}

Instead of wading through the description of all the options, you can jump to 3.4.3 Short Options Cross Reference under the info tar command.

x means --extract. v means --verbose. f means --file. z means --gzip. You can combine one-letter arguments together, and f takes an argument, the filename. There is something you have to watch out for:

Short options' letters may be clumped together, but you are not required to do this (as compared to old options; see below). When short options are clumped as a set, use one (single) dash for them all, e.g., ''tar' -cvf'. Only the last option in such a set is allowed to have an argument(1).

---

This old way of writing 'tar' options can surprise even experienced users. For example, the two commands:

 tar cfz archive.tar.gz file
 tar -cfz archive.tar.gz file

are quite different. The first example uses 'archive.tar.gz' as the value for option 'f' and recognizes the option 'z'. The second example, however, uses 'z' as the value for option 'f' -- probably not what was intended.

System.Web.UI contained the Pair class because it was used heavily in ASP.NET 1.1 as an internal ViewState structure.

Update Aug 2017: C# 7.0 / .NET Framework 4.7 provides a syntax to declare a Tuple with named items using the System.ValueTuple struct.

//explicit Item typing
(string Message, int SomeNumber) t = ("Hello", 4);
//or using implicit typing 
var t = (Message:"Hello", SomeNumber:4);

Console.WriteLine("{0} {1}", t.Message, t.SomeNumber);

see MSDN for more syntax examples.

Update Jun 2012: Tuples have been a part of .NET since version 4.0.

Here is an earlier article describing inclusion in.NET4.0 and support for generics:

Tuple<string, int> t = new Tuple<string, int>("Hello", 4);

Perhaps you could try ([^ ]+) .*, which should give you everything to the first blank in your first group.

I asked this same question: How can I get the button that caused the submit from the form submit event?

I ended up coming up with this solution and it worked pretty well:

$(document).ready(function() {
    $("form").submit(function() { 
        var val = $("input[type=submit][clicked=true]").val();
        // DO WORK
    });
    $("form input[type=submit]").click(function() {
        $("input[type=submit]", $(this).parents("form")).removeAttr("clicked");
        $(this).attr("clicked", "true");
    });
});

In your case with multiple forms you may need to tweak this a bit but it should still apply

The problem is that your regex is a string, but html is bytes:

>>> type(html)
<class 'bytes'>

Since python doesn't know how those bytes are encoded, it throws an exception when you try to use a string regex on them.

You can either decode the bytes to a string:

html = html.decode('ISO-8859-1')  # encoding may vary!
title = re.findall(pattern, html)  # no more error

Or use a bytes regex:

regex = rb'<title>(,+?)</title>'
#        ^

In this particular context, you can get the encoding from the response headers:

with urllib.request.urlopen(url) as response:
    encoding = response.info().get_param('charset', 'utf8')
    html = response.read().decode(encoding)

See the urlopen documentation for more details.

Let's see how your algorithm works:

an array of unique values:

[1, 2, 3]

check 1 == 1. yes, there is duplicate, assigning duplicate to true.
check 1 == 2. no, doing nothing.
check 1 == 3. no, doing nothing.
check 2 == 1. no, doing nothing.
check 2 == 2. yes, there is duplicate, assigning duplicate to true.
check 2 == 3. no, doing nothing.
check 3 == 1. no, doing nothing.
check 3 == 2. no, doing nothing.
check 3 == 3. yes, there is duplicate, assigning duplicate to true.

a better algorithm:

for (j=0;j<zipcodeList.length;j++) {
    for (k=j+1;k<zipcodeList.length;k++) {
        if (zipcodeList[k]==zipcodeList[j]){ // or use .equals()
            return true;
        }
    }
}
return false;

This error mostly comes when we forcefully kill the weblogic server ("kill -9 process id"), so before restart kindly check all the ports status which weblogic using e.g. http port , DEBUG_PORT etc by using this command to see which whether this port is active or not.

netstat –an | grep (Admin: 7001 or something, Managed server- 7002, 7003 etc) eg: netstat –an | grep 7001

If it returns value then, option 1: wait for some time, so that background process can release the port option 2: execute stopweblogic.sh Option 3: Bounce the server/host or restart the system.

My issue was resolved by option 2.

Use case match for early return purpose. It will force you to declare all return branches explicitly, preventing the careless mistake of forgetting to write return somewhere.

You could try a different approach like read the file line by line instead of dealing with all this nl2br / explode stuff.

$fh = fopen("employees.txt", "r"); if ($fh) {     while (($line = fgets($fh)) !== false) {         $line = trim($line);         echo "<option value='".$line."'>".$line."</option>";     } } else {     // error opening the file, do something } 

Also maybe just doing a trim (remove whitespace from beginning/end of string) is your issue?

And maybe people are just misunderstanding what you mean by "submitting results to a spreadsheet" -- are you doing this with code? or a copy/paste from an HTML page into a spreadsheet? Maybe you can explain that in more detail. The delimiter for which you split the lines of the file shouldn't be displaying in the output anyway unless you have unexpected output for some other reason.

Plot the statistical autocorrelation given a pandas datatime Series of returns:

import matplotlib.pyplot as plt

def plot_autocorr(returns, lags):
    autocorrelation = []
    for lag in range(lags+1):
        corr_lag = returns.corr(returns.shift(-lag)) 
        autocorrelation.append(corr_lag)
    plt.plot(range(lags+1), autocorrelation, '--o')
    plt.xticks(range(lags+1))
    return np.array(autocorrelation)

You can simply place multiple name together separated by a white space like

C:\Users\Dell>pip install markdown django-filter

#c:\Users\Dell is path in my pc this can be anything on yours

this installed markdown and django-filter on my device.

There's no way this could influence anything in Java, since there's no (direct non-API) way to map some bytes directly into an int in Java.

Every API that does this or something similar defines the behaviour pretty precisely, so you should look up the documentation of that API.

You add your ActionListener twice to button. So correct your code for button2 to

  JButton button2 = new JButton("hello agin2");
  panel.add(button2);
  button2.addActionListener (new Action2());//note the button2 here instead of button

Furthermore, perform your Swing operations on the correct thread by using EventQueue.invokeLater

my experience tells me that missing persistence.xml,will generate the same exception too.

i caught the same error msg today when i tried to run a jar package packed by ant.

when i used jar tvf to check the content of the jar file, i realized that "ant" forgot to pack the persistnece.xml for me.

after I manually repacked the jar file ,the error msg disappered.

so i believe maybe you should try simplely putting META-INF under src directory and placing your persistence.xml there.

You can use SimpleDateformat for change string to date

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
String strDate = "2000-01-01";
Date date = sdf.parse(strDate);

Since @Doua Beri is experiencing connection close even when there are 1 Hz SENDs, it may be instead be due to size limits on messages.

This passage from Spring's WebSockets may be useful, with my emphasis ...

Although in theory a WebSocket message can be almost unlimited in size, in practice WebSocket servers impose limits — for example, 8K on Tomcat and 64K on Jetty. For this reason STOMP clients such as stomp.js split larger STOMP messages at 16K boundaries and send them as multiple WebSocket messages thus requiring the server to buffer and re-assemble.

Your EditText should be wrapped in a TextInputLayout

<android.support.design.widget.TextInputLayout
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:id="@+id/tilEmail">

    <EditText
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:inputType="textEmailAddress"
        android:ems="10"
        android:id="@+id/etEmail"
        android:hint="Email"
        android:layout_marginTop="10dp"
        />

</android.support.design.widget.TextInputLayout>

To get an error message like you wanted, set error to TextInputLayout

TextInputLayout tilEmail = (TextInputLayout) findViewById(R.id.tilEmail);
if (error){
    tilEmail.setError("Invalid email id");    
}

You should add design support library dependency. Add this line in your gradle dependencies

compile 'com.android.support:design:22.2.0'

When you start a thread you are executing a method of some chosen class. All attributes of that class are visible.

  Worker myWorker = new Worker( /* arguments */ );

  Thread myThread = new Thread(new ThreadStart(myWorker.doWork));

  myThread.Start();

Your thread is now in the doWork() method and can see any atrributes of myWorker, which may themselves be other objects. Now you just need to be careful to deal with the cases of having several threads all hitting those attributes at the same time.

This is how I used clearInterval() method to stop the timer after 10 seconds.

function startCountDown() {_x000D_
  var countdownNumberEl = document.getElementById('countdown-number');_x000D_
  var countdown = 10;_x000D_
  const interval = setInterval(() => {_x000D_
    countdown = --countdown <= 0 ? 10 : countdown;_x000D_
    countdownNumberEl.textContent = countdown;_x000D_
    if (countdown == 1) {_x000D_
      clearInterval(interval);_x000D_
    }_x000D_
  }, 1000)_x000D_
}

<head>_x000D_
  <body>_x000D_
    <button id="countdown-number" onclick="startCountDown();">Show Time </button>_x000D_
  </body>_x000D_
</head>

Parameters are directly supported in MVC by simply adding parameters onto your action methods. Given an action like the following:

public ActionResult GetImages(string artistName, string apiKey)

MVC will auto-populate the parameters when given a URL like:

/Artist/GetImages/?artistName=cher&apiKey=XXX

One additional special case is parameters named "id". Any parameter named ID can be put into the path rather than the querystring, so something like:

public ActionResult GetImages(string id, string apiKey)

would be populated correctly with a URL like the following:

/Artist/GetImages/cher?apiKey=XXX

In addition, if you have more complicated scenarios, you can customize the routing rules that MVC uses to locate an action. Your global.asax file contains routing rules that can be customized. By default the rule looks like this:

routes.MapRoute(
            "Default",                                              // Route name
            "{controller}/{action}/{id}",                           // URL with parameters
            new { controller = "Home", action = "Index", id = "" }  // Parameter defaults
        );

If you wanted to support a url like

/Artist/GetImages/cher/api-key

you could add a route like:

routes.MapRoute(
            "ArtistImages",                                              // Route name
            "{controller}/{action}/{artistName}/{apikey}",                           // URL with parameters
            new { controller = "Home", action = "Index", artistName = "", apikey = "" }  // Parameter defaults
        );

and a method like the first example above.

If the date is valid then the getTime() will always be equal to itself.

var date = new Date('2019-12-12');
if(date.getTime() - date.getTime() === 0) {
    console.log('Date is valid');
} else {
    console.log('Date is invalid');
}

Run the following command in terminal:

sudo ln -s /usr/share/phpmyadmin /var/www/html/

You can use compileall in the terminal. The following command will go recursively into sub directories and make pyc files for all the python files it finds. The compileall module is part of the python standard library, so you don't need to install anything extra to use it. This works exactly the same way for python2 and python3.

python -m compileall .

Thanks for the research FIRESTICK is a solution for non Android based but there's another one Im using if you guys want to try it let me know...

LG, VIZIO, SAMSUNG and PANASONIC TVs are not android based, and you cannot run APKs off of them... You should just buy a fire stick and call it a day. The only TVs that are android-based, and you can install APKs are: SONY, PHILIPS and SHARP, PHILCO and TOSHIBA.

No, there is not, see how the "Related XML Attributes" section is missing in the ImageView.setAlpha(int) documentation. The alternative is to use View.setAlpha(float) whose XML counterpart is android:alpha. It takes a range of 0.0 to 1.0 instead of 0 to 255. Use it e.g. like

<ImageView android:alpha="0.4">

However, the latter in available only since API level 11.

W3Schools is your friend: http://www.w3schools.com/php/func_filesystem_fgets.asp

And here: http://php.net/manual/en/function.fopen.php has more info on fopen including what the modes are.

What W3Schools says:

<?php
$file = fopen("test.txt","r");

while(! feof($file))
  {
  echo fgets($file). "<br />";
  }

fclose($file);
?> 

fopen opens the file (in this case test.txt with mode 'r' which means read-only and places the pointer at the beginning of the file)

The while loop tests to check if it's at the end of file (feof) and while it isn't it calls fgets which gets the current line where the pointer is.

Continues doing this until it is the end of file, and then closes the file.

I've encountered this problem when copying a git repo with working files from an old hard drive a couple times. The problem stems from the fact that the owner and permissions changed from the old drive/machine to the new one. The long and short of it is, run the following commands to straighten things out (thanks to this superuser answer):

sudo chmod -R -x . # remove the executable bit from all files

The former command will actually resolve the differences that git diff reported, but will revoke your ability to list the directories, so ls ./ fails with ls: .: Permission denied. To fix that:

sudo chmod -R +X . # add the executable bit only for directories

The bad news is that if you do have any files you want to keep executable, such as .sh scripts, you'll need to revert those. You can do that with the following command for each file:

chmod +x ./build.sh # where build.sh is the file you want to make executable again

I'm quite ashamed that there are so many incorrect or undisclosed partial applicability.

The easiest way to do this is through Chrome or Opera (my examples will use Chrome) using the Console. Enter the following code into the console (generally in 1 line):

var l = document.getElementById('testLink');
for(var i=0; i<5; i++){
  l.click();
}

This will generate the required result

Your system does not have a GUI manager. Happens mostly in Solaris/Linux boxes. If you are using GUI in them make sure that you have a GUI manager installed and you may also want to google through the DISPLAY variable.

One significant difference between INNER JOIN and NATURAL JOIN is the number of columns returned.

Consider:

TableA                           TableB
+------------+----------+        +--------------------+    
|Column1     | Column2  |        |Column1  |  Column3 |
+-----------------------+        +--------------------+
| 1          |  2       |        | 1       |   3      |
+------------+----------+        +---------+----------+

The INNER JOIN of TableA and TableB on Column1 will return

SELECT * FROM TableA AS a INNER JOIN TableB AS b USING (Column1);
SELECT * FROM TableA AS a INNER JOIN TableB AS b ON a.Column1 = b.Column1;

+------------+-----------+---------------------+    
| a.Column1  | a.Column2 | b.Column1| b.Column3|
+------------------------+---------------------+
| 1          |  2        | 1        |   3      |
+------------+-----------+----------+----------+

The NATURAL JOIN of TableA and TableB on Column1 will return:

SELECT * FROM TableA NATURAL JOIN TableB
+------------+----------+----------+    
|Column1     | Column2  | Column3  |
+-----------------------+----------+
| 1          |  2       |   3      |
+------------+----------+----------+

The repeated column is avoided.

(AFAICT from the standard grammar, you can't specify the joining columns in a natural join; the join is strictly name-based. See also Wikipedia.)

(There's a cheat in the inner join output; the a. and b. parts would not be in the column names; you'd just have column1, column2, column1, column3 as the headings.)

For me, IIS Express was not accessible when I added iplisten on DOS Prompt like this: netsh http add iplisten MyIPAddress. I fixed it by deleting the iplisten like this: netsh http delete iplisten MyIPAddress.

it can take a bit of time before a closed socket is really freed up

You can use Reflection to do this: (from my library - this gets the names and values)

public static Dictionary<string, object> DictionaryFromType(object atype)
{
    if (atype == null) return new Dictionary<string, object>();
    Type t = atype.GetType();
    PropertyInfo[] props = t.GetProperties();
    Dictionary<string, object> dict = new Dictionary<string, object>();
    foreach (PropertyInfo prp in props)
    {
        object value = prp.GetValue(atype, new object[]{});
        dict.Add(prp.Name, value);
    }
    return dict;
}

This thing will not work for properties with an index - for that (it's getting unwieldy):

public static Dictionary<string, object> DictionaryFromType(object atype, 
     Dictionary<string, object[]> indexers)
{
    /* replace GetValue() call above with: */
    object value = prp.GetValue(atype, ((indexers.ContainsKey(prp.Name)?indexers[prp.Name]:new string[]{});
}

Also, to get only public properties: (see MSDN on BindingFlags enum)

/* replace */
PropertyInfo[] props = t.GetProperties();
/* with */
PropertyInfo[] props = t.GetProperties(BindingFlags.Public)

This works on anonymous types, too!
To just get the names:

public static string[] PropertiesFromType(object atype)
{
    if (atype == null) return new string[] {};
    Type t = atype.GetType();
    PropertyInfo[] props = t.GetProperties();
    List<string> propNames = new List<string>();
    foreach (PropertyInfo prp in props)
    {
        propNames.Add(prp.Name);
    }
    return propNames.ToArray();
}

And it's just about the same for just the values, or you can use:

GetDictionaryFromType().Keys
// or
GetDictionaryFromType().Values

But that's a bit slower, I would imagine.

"Jaap van Hengstum"'s answer is working for me, but there is no need to set "android:windowSoftInputMode" as he just said!

I've made it smaller(it now just detects what I want, actually an event on showing and hiding of keyboard):

private ViewTreeObserver.OnGlobalLayoutListener keyboardLayoutListener = new ViewTreeObserver.OnGlobalLayoutListener() {
    @Override
    public void onGlobalLayout() {
        int heightDiff = rootLayout.getRootView().getHeight() - rootLayout.getHeight();
        int contentViewTop = getWindow().findViewById(Window.ID_ANDROID_CONTENT).getTop();
        if(heightDiff <= contentViewTop){
            onHideKeyboard();
        } else {
            onShowKeyboard();
        }
    }
};

private boolean keyboardListenersAttached = false;
private ViewGroup rootLayout;

protected void onShowKeyboard() {}
protected void onHideKeyboard() {}

protected void attachKeyboardListeners() {
    if (keyboardListenersAttached) {
        return;
    }

    rootLayout = (ViewGroup) findViewById(R.id.CommentsActivity);
    rootLayout.getViewTreeObserver().addOnGlobalLayoutListener(keyboardLayoutListener);

    keyboardListenersAttached = true;
}

@Override
protected void onDestroy() {
    super.onDestroy();

    if (keyboardListenersAttached) {
        rootLayout.getViewTreeObserver().removeGlobalOnLayoutListener(keyboardLayoutListener);
    }
}

and just don't forget to add this

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_comments);
    attachKeyboardListeners();}

What Works:

string relativePath = "..\\bling.txt";
string baseDirectory = "C:\\blah\\";
string absolutePath = Path.GetFullPath(baseDirectory + relativePath);

(result: absolutePath="C:\bling.txt")

What doesn't work

string relativePath = "..\\bling.txt";
Uri baseAbsoluteUri = new Uri("C:\\blah\\");
string absolutePath = new Uri(baseAbsoluteUri, relativePath).AbsolutePath;

If the browser uses this attribute, it is only as an help for the user, so he won't upload a multi-megabyte file just to see it rejected by the server...
Same for the <input type="hidden" name="MAX_FILE_SIZE" value="100000"> tag: if the browser uses it, it won't send the file but an error resulting in UPLOAD_ERR_FORM_SIZE (2) error in PHP (not sure how it is handled in other languages).
Note these are helps for the user. Of course, the server must always check the type and size of the file on its end: it is easy to tamper with these values on the client side.

I think you shouldn't prepend themesDir. You only pass the filename of the template to flask, it will then look in a folder called templates relative to your python file.

Just use a UIButton, its already built in. Turn off all the extra button features and you have a label that you can set edge instets on.

let button = UIButton()
button.contentEdgeInsets = UIEdgeInsets(top: 5, left: 5, bottom: 5, right: 5)
button.setTitle("title", for: .normal)
button.tintColor = .white // this will be the textColor
button.isUserInteractionEnabled = false

It may be caused by IE's box model bug. To fix this, you can use the Box Model Hack.

I concurr with @marc_s and @Adam_Poward -- DateTime2 is the preferred method moving forward. It has a wider range of dates, higher precision, and uses equal or less storage (depending on precision).

One thing the discussion missed, however...
@Marc_s states: Both types map to System.DateTime in .NET - no difference there. This is correct, however, the inverse is not true...and it matters when doing date range searches (e.g. "find me all records modified on 5/5/2010").

.NET's version of Datetime has similar range and precision to DateTime2. When mapping a .net Datetime down to the old SQL DateTime an implicit rounding occurs. The old SQL DateTime is accurate to 3 milliseconds. This means that 11:59:59.997 is as close as you can get to the end of the day. Anything higher is rounded up to the following day.

Try this :

declare @d1 datetime   = '5/5/2010 23:59:59.999'
declare @d2 datetime2  = '5/5/2010 23:59:59.999'
declare @d3 datetime   = '5/5/2010 23:59:59.997'
select @d1 as 'IAmMay6BecauseOfRounding', @d2 'May5', @d3 'StillMay5Because2msEarlier'

Avoiding this implicit rounding is a significant reason to move to DateTime2. Implicit rounding of dates clearly causes confusion:

In addition to the accepted answer I would like to give an answer that shows how to iterate directly over the Newtonsoft collections. It uses less code and I'm guessing its more efficient as it doesn't involve converting the collections.

using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
//Parse the data
JObject my_obj = JsonConvert.DeserializeObject<JObject>(your_json);

foreach (KeyValuePair<string, JToken> sub_obj in (JObject)my_obj["ADDRESS_MAP"])
{
    Console.WriteLine(sub_obj.Key);
}

I started doing this myself because JsonConvert automatically deserializes nested objects as JToken (which are JObject, JValue, or JArray underneath I think).

I think the parsing works according to the following principles:

• Every object is abstracted as a JToken

• Cast to JObject where you expect a Dictionary

• Cast to JValue if the JToken represents a terminal node and is a value

• Cast to JArray if its an array

• JValue.Value gives you the .NET type you need

Thanks to @user2630576 and @Ed.S.

the following worked a treat:

BACKUP LOG [database] TO DISK = 'D:\database.bak'
GO

ALTER DATABASE [database] SET RECOVERY SIMPLE

use [database]

declare @log_File_Name varchar(200)

select @log_File_Name = name from sysfiles where filename like '%LDF'

declare @i int = FILE_IDEX ( @log_File_Name)

dbcc shrinkfile ( @i , 50)

ALTER DATABASE [database] SET RECOVERY FULL

If you don't want to chain (a huge number of) try-except clauses, you may try your codes in a loop and break upon 1st success.

Example with codes which can be put into functions:

for code in (
    lambda: a / b,
    lambda: a / (b + 1),
    lambda: a / (b + 2),
    ):
    try: print(code())
    except Exception as ev: continue
    break
else:
    print("it failed: %s" % ev)

Example with arbitrary codes (statements) directly in the current scope:

for i in 2, 1, 0:
    try:
        if   i == 2: print(a / b)
        elif i == 1: print(a / (b + 1))
        elif i == 0: print(a / (b + 2))
        break        
    except Exception as ev:
        if i:
            continue
        print("it failed: %s" % ev)

Use the ternary operator:

name = ((city.getName() == null) ? "N/A" : city.getName());

I think you have the conditions backwards - if it's null, you want the value to be "N/A".

What if city is null? Your code *hits the bed in that case. I'd add another check:

name = ((city == null) || (city.getName() == null) ? "N/A" : city.getName());

I've used C++ namespaces the same way I do in C#, Perl, etc. It's just a semantic separation of symbols between standard library stuff, third party stuff, and my own code. I would place my own app in one namespace, then a reusable library component in another namespace for separation.

Run below commands in Terminal:

npm install --save-dev webpack

npm install --save-dev webpack-dev-server

You need to delimit each parameter name with a ":" at the very least. Technically the name is optional, but it is recommended for readability. So you could write:

- (NSMutableArray*)getBusStops:(NSString*)busStop :(NSSTimeInterval*)timeInterval;

or what you suggested:

- (NSMutableArray*)getBusStops:(NSString*)busStop forTime:(NSSTimeInterval*)timeInterval;

Try removing "package-lock.json" and running "npm install && npm update", it'll install the latest version and clear all errors.

This is a good description of its uses and shortcomings. You essentially use it whenever you need to do fast low-level I/O. If you were going to implement a TCP/IP protocol or if you were writing a database (DBMS) this class would come in handy.

Here is my approach that you may try:

import numpy as np
import matplotlib.pyplot as plt

w=10
h=10
fig=plt.figure(figsize=(8, 8))
columns = 4
rows = 5
for i in range(1, columns*rows +1):
    img = np.random.randint(10, size=(h,w))
    fig.add_subplot(rows, columns, i)
    plt.imshow(img)
plt.show()

The resulting image:

Edit 1

Since this answer is popular beyond my expectation. And I see that a small change is needed to enable flexibility for the manipulation of the individual plots. So that I offer this new version to the original code. In essence, it provides:-

1. access to individual axes of subplots
2. possibility to plot more features on selected axes/subplot

New code:

import numpy as np
import matplotlib.pyplot as plt

w = 10
h = 10
fig = plt.figure(figsize=(9, 13))
columns = 4
rows = 5

# prep (x,y) for extra plotting
xs = np.linspace(0, 2*np.pi, 60)  # from 0 to 2pi
ys = np.abs(np.sin(xs))           # absolute of sine

# ax enables access to manipulate each of subplots
ax = []

for i in range(columns*rows):
    img = np.random.randint(10, size=(h,w))
    # create subplot and append to ax
    ax.append( fig.add_subplot(rows, columns, i+1) )
    ax[-1].set_title("ax:"+str(i))  # set title
    plt.imshow(img, alpha=0.25)

# do extra plots on selected axes/subplots
# note: index starts with 0
ax[2].plot(xs, 3*ys)
ax[19].plot(ys**2, xs)

plt.show()  # finally, render the plot

The resulting plot:

Edit 2

In the previous example, the code provides access to the sub-plots with single index, which is inconvenient when the figure has many rows/columns of sub-plots. Here is an alternative of it. The code below provides access to the sub-plots with [row_index][column_index], which is more suitable for manipulation of array of many sub-plots.

import matplotlib.pyplot as plt
import numpy as np

# settings
h, w = 10, 10        # for raster image
nrows, ncols = 5, 4  # array of sub-plots
figsize = [6, 8]     # figure size, inches

# prep (x,y) for extra plotting on selected sub-plots
xs = np.linspace(0, 2*np.pi, 60)  # from 0 to 2pi
ys = np.abs(np.sin(xs))           # absolute of sine

# create figure (fig), and array of axes (ax)
fig, ax = plt.subplots(nrows=nrows, ncols=ncols, figsize=figsize)

# plot simple raster image on each sub-plot
for i, axi in enumerate(ax.flat):
    # i runs from 0 to (nrows*ncols-1)
    # axi is equivalent with ax[rowid][colid]
    img = np.random.randint(10, size=(h,w))
    axi.imshow(img, alpha=0.25)
    # get indices of row/column
    rowid = i // ncols
    colid = i % ncols
    # write row/col indices as axes' title for identification
    axi.set_title("Row:"+str(rowid)+", Col:"+str(colid))

# one can access the axes by ax[row_id][col_id]
# do additional plotting on ax[row_id][col_id] of your choice
ax[0][2].plot(xs, 3*ys, color='red', linewidth=3)
ax[4][3].plot(ys**2, xs, color='green', linewidth=3)

plt.tight_layout(True)
plt.show()

The resulting plot:

Use the source, Luke!

In CPython, range(...).__contains__ (a method wrapper) will eventually delegate to a simple calculation which checks if the value can possibly be in the range. The reason for the speed here is we're using mathematical reasoning about the bounds, rather than a direct iteration of the range object. To explain the logic used:

1. Check that the number is between start and stop, and
2. Check that the stride value doesn't "step over" our number.

For example, 994 is in range(4, 1000, 2) because:

1. 4 <= 994 < 1000, and
2. (994 - 4) % 2 == 0.

The full C code is included below, which is a bit more verbose because of memory management and reference counting details, but the basic idea is there:

static int
range_contains_long(rangeobject *r, PyObject *ob)
{
    int cmp1, cmp2, cmp3;
    PyObject *tmp1 = NULL;
    PyObject *tmp2 = NULL;
    PyObject *zero = NULL;
    int result = -1;

    zero = PyLong_FromLong(0);
    if (zero == NULL) /* MemoryError in int(0) */
        goto end;

    /* Check if the value can possibly be in the range. */

    cmp1 = PyObject_RichCompareBool(r->step, zero, Py_GT);
    if (cmp1 == -1)
        goto end;
    if (cmp1 == 1) { /* positive steps: start <= ob < stop */
        cmp2 = PyObject_RichCompareBool(r->start, ob, Py_LE);
        cmp3 = PyObject_RichCompareBool(ob, r->stop, Py_LT);
    }
    else { /* negative steps: stop < ob <= start */
        cmp2 = PyObject_RichCompareBool(ob, r->start, Py_LE);
        cmp3 = PyObject_RichCompareBool(r->stop, ob, Py_LT);
    }

    if (cmp2 == -1 || cmp3 == -1) /* TypeError */
        goto end;
    if (cmp2 == 0 || cmp3 == 0) { /* ob outside of range */
        result = 0;
        goto end;
    }

    /* Check that the stride does not invalidate ob's membership. */
    tmp1 = PyNumber_Subtract(ob, r->start);
    if (tmp1 == NULL)
        goto end;
    tmp2 = PyNumber_Remainder(tmp1, r->step);
    if (tmp2 == NULL)
        goto end;
    /* result = ((int(ob) - start) % step) == 0 */
    result = PyObject_RichCompareBool(tmp2, zero, Py_EQ);
  end:
    Py_XDECREF(tmp1);
    Py_XDECREF(tmp2);
    Py_XDECREF(zero);
    return result;
}

static int
range_contains(rangeobject *r, PyObject *ob)
{
    if (PyLong_CheckExact(ob) || PyBool_Check(ob))
        return range_contains_long(r, ob);

    return (int)_PySequence_IterSearch((PyObject*)r, ob,
                                       PY_ITERSEARCH_CONTAINS);
}

The "meat" of the idea is mentioned in the line:

/* result = ((int(ob) - start) % step) == 0 */ 

As a final note - look at the range_contains function at the bottom of the code snippet. If the exact type check fails then we don't use the clever algorithm described, instead falling back to a dumb iteration search of the range using _PySequence_IterSearch! You can check this behaviour in the interpreter (I'm using v3.5.0 here):

>>> x, r = 1000000000000000, range(1000000000000001)
>>> class MyInt(int):
...     pass
... 
>>> x_ = MyInt(x)
>>> x in r  # calculates immediately :) 
True
>>> x_ in r  # iterates for ages.. :( 
^\Quit (core dumped)

Like this:

numrows = len(input)    # 3 rows in your example
numcols = len(input[0]) # 2 columns in your example

Assuming that all the sublists have the same length (that is, it's not a jagged array).

You could can use git rebase to rewrite the commit history. This can be potentially destructive to your changes, so use with care.

First commit your "amend" change as a normal commit. Then do an interactive rebase starting on the parent of your oldest commit

git rebase -i 47175e84c2cb7e47520f7dde824718eae3624550^

This will fire up your editor with all commits. Reorder them so your "amend" commit comes below the one you want to amend. Then replace the first word on the line with the "amend" commit with s which will combine (s quash) it with the commit before. Save and exit your editor and follow the instructions.

This is another random number generator that i use often, it also prevent the first digit from been zero(0)

  function randomNumber(length) {_x000D_
    var text = "";_x000D_
    var possible = "123456789";_x000D_
    for (var i = 0; i < length; i++) {_x000D_
      var sup = Math.floor(Math.random() * possible.length);_x000D_
      text += i > 0 && sup == i ? "0" : possible.charAt(sup);_x000D_
    }_x000D_
    return Number(text);_x000D_
  }

All answers are good, there is another way of doing, which is list comprehension, see the solution below.

u = "UUUDDD"

lst = [x for x in u]

for comma separated list do the following

u = "U,U,U,D,D,D"

lst = [x for x in u.split(',')]

I am using JavaScript but some of the principles are common I am sure.

The code I am using is as follows:

    var s = new webdriver.ActionSequence(d);
    d.findElement(By.className('fc-time')).then(function(result){
        s.mouseMove(result,l).click().perform();
    });

the driver = d. The location = l is simply {x:300,y:500) - it is just an offset.

What I found during my testing was that I could not make it work without using the method to find an existing element first, using that at a basis from where to locate my click.

I suspect the figures in the locate are a bit more difficult to predict than I thought.

It is an old post but this response may help other newcomers like me.

User can use this

Dim todaysdate As String = String.Format("{0:dd/MM/yyyy}", DateTime.Now)

this will format the date as required whereas user can change the string type dd/MM/yyyy or MM/dd/yyyy or yyyy/MM/dd or even can have this format to get the time from date

yyyy/MM/dd HH:mm:ss 

The major difference between these tools is how they copy files.

scp basically reads the source file and writes it to the destination. It performs a plain linear copy, locally, or over a network.

rsync also copies files locally or over a network. But it employs a special delta transfer algorithm and a few optimizations to make the operation a lot faster. Consider the call.

rsync A host:B

• rsync will check files sizes and modification timestamps of both A and B, and skip any further processing if they match.

• If the destination file B already exists, the delta transfer algorithm will make sure only differences between A and B are sent over the wire.

• rsync will write data to a temporary file T, and then replace the destination file B with T to make the update look "atomic" to processes that might be using B.

Another difference between them concerns invocation. rsync has a plethora of command line options, allowing the user to fine tune its behavior. It supports complex filter rules, runs in batch mode, daemon mode, etc. scp has only a few switches.

In summary, use scp for your day to day tasks. Commands that you type once in a while on your interactive shell. It's simpler to use, and in those cases rsync optimizations won't help much.

For recurring tasks, like cron jobs, use rsync. As mentioned, on multiple invocations it will take advantage of data already transferred, performing very quickly and saving on resources. It is an excellent tool to keep two directories synchronized over a network.

Also, when dealing with large files, use rsync with the -P option. If the transfer is interrupted, you can resume it where it stopped by reissuing the command. See Sid Kshatriya's answer.

You can pass multiple parameters as "?param1=value1&param2=value2"

But it's not secure. It's vulnerable to Cross Site Scripting (XSS) Attack.

Your parameter can be simply replaced with a script.

Have a look at this article and article

You can make it secure by using API of StringEscapeUtils

static String   escapeHtml(String str) 
          Escapes the characters in a String using HTML entities.

Even using https url for security without above precautions is not a good practice.

Have a look at related SE question:

Is URLEncoder.encode(string, "UTF-8") a poor validation?

Another way by using ajax method:

View:

@Html.TextBox("txtValue", null, new { placeholder = "Input value" })
<input type="button" value="Start" id="btnStart"  />

<script>
    $(function () {
        $('#btnStart').unbind('click');
        $('#btnStart').on('click', function () {
            $.ajax({
                url: "/yourControllerName/yourMethod",
                type: 'POST',
                contentType: "application/json; charset=utf-8",
                dataType: 'json',
                data: JSON.stringify({
                    txtValue: $("#txtValue").val()
                }),
                async: false
            });
       });
   });
</script>

Controller:

[HttpPost]
public EmptyResult YourMethod(string txtValue)
{
    // do what you want with txtValue
    ...
}

It seems that the only correct answer here so far has been given by romnex: "onDestroy() may not be called at all". Even though in practice, in almost all cases it will, there is no guarantee: The documentation on finish() only promises that the result of the activity is propagated back to the caller, but nothing more. Moreover, the lifecycle documentation clarifies that the activity is killable by the OS as soon as onStop() finishes (or even earlier on older devices), which, even though unlikely and therefore rare to observe in a simple test, might mean that the activity might be killed while or even before onDestroy() is executed.

So if you want to make sure some work is done when you call finish(), you cannot put it in onDestroy(), but will need to do in the same place where you call finish(), right before actually calling it.
