The following should work:

cin.flush();

On some systems it's not available and then you can use:

cin.ignore(INT_MAX);

> df <- data.frame(matrix(ncol = 300, nrow = 100))
> dim(df)
[1] 100 300

Another very simple yet noobish mistake of mine: I simply forgot to add a message -m modifier in my commit. So I wrote:

git commit 'My message'

Instead of correct:

git commit -m 'My message'

NOTE: It does NOT throw any errors! But you will not be able to push your commits and always get Everything up to date instead

Here is a great working regex for numbers. This accepts number with commas and decimals.

/^-?(?:\d+|\d{1,3}(?:,\d{3})+)?(?:\.\d+)?$/

Thank you Majid Laissi for your answer

I made 2 functions out from your code:

the goal was to implement convertation of string to VARBINARY, BINARY and back

const stringToBinary = function(string, maxBytes) {
  //for BINARY maxBytes = 255
  //for VARBINARY maxBytes = 65535
  let binaryOutput = '';
  if (string.length > maxBytes) {
    string = string.substring(0, maxBytes);
  }

  for (var i = 0; i < string.length; i++) {
    binaryOutput += string[i].charCodeAt(0).toString(2) + ' ';
  }

  return binaryOutput;
};

and backward convertation:

const binaryToString = function(binary) {
  const arrayOfBytes = binary.split(' ');

  let stringOutput = '';

  for (let i = 0; i < arrayOfBytes.length; i++) {
    stringOutput += String.fromCharCode(parseInt(arrayOfBytes[i], 2));
  }

  return stringOutput;
};

and here is a working example: https://jsbin.com/futalidenu/edit?js,console

The following worked for me:

ForceCursor = true;
Cursor = Cursors.Wait;

From php7 you can use Null Coalesce Opperator:

$employee = $mentors->intern ?? $mentors->intern->employee

This will return Null or the employee.

The approach you're looking for is FillDown. Another way so you don't have to kick your head off every time is to store formulas in an array of strings. Combining them gives you a powerful method of inputting formulas by the multitude. Code follows:

Sub FillDown()

    Dim strFormulas(1 To 3) As Variant

    With ThisWorkbook.Sheets("Sheet1")
        strFormulas(1) = "=SUM(A2:B2)"
        strFormulas(2) = "=PRODUCT(A2:B2)"
        strFormulas(3) = "=A2/B2"

        .Range("C2:E2").Formula = strFormulas
        .Range("C2:E11").FillDown
    End With

End Sub

Screenshots:

Result as of line: .Range("C2:E2").Formula = strFormulas:

Result as of line: .Range("C2:E11").FillDown:

Of course, you can make it dynamic by storing the last row into a variable and turning it to something like .Range("C2:E" & LRow).FillDown, much like what you did.

Hope this helps!

JMF was abandoned. VLC is more up to date and it reads everything. https://stackoverflow.com/a/5160010

I think vlc beats every other software out there yet, or at least the ones that I know...

Example #1:

class A{
 void met(){
   Class.forName("com.example.Class1");
 }
}

If com/example/Class1 doesn't exist in any of the classpaths, then It throws ClassNotFoundException.

Example #2:

Class B{
  void met(){
   com.example.Class2 c = new com.example.Class2();
 }
}

If com/example/Class2 existed while compiling B, but not found while execution, then It throws NoClassDefFoundError.

Both are run time exceptions.

The problem is in the refresh token:

[refresh_token] => 1\/lov250YQTMCC9LRQbE6yMv-FiX_Offo79UXimV8kvwY

When a string with a '/' gets json encoded, It is escaped with a '\', hence you need to remove it.

The refresh token in your case should be:

1/lov250YQTMCC9LRQbE6yMv-FiX_Offo79UXimV8kvwY

What i'm assuming you've done is that you've printed the json string which google sent back and copied and pasted the token into your code because if you json_decode it then it will correctly remove the '\' for you!

It seems like you have it worked out, but for others looking for this answer, an easy way to do this is by printing to stderr. You can do that like this:

from __future__ import print_function # In python 2.7
import sys

@app.route('/button/')
def button_clicked():
    print('Hello world!', file=sys.stderr)
    return redirect('/')

Flask will display things printed to stderr in the console. For other ways of printing to stderr, see this stackoverflow post

The equivalent syntax since DataTables 1.10+ is rowCallback

"rowCallback": function( row, data, index ) {
    if ( data[2] == "5" )
    {
        $('td', row).css('background-color', 'Red');
    }
    else if ( data[2] == "4" )
    {
        $('td', row).css('background-color', 'Orange');
    }
}

One of the previous answers mentions createdRow. That may give similar results under some conditions, but it is not the same. For example, if you use draw() after updating a row's data, createdRow will not run. It only runs once. rowCallback will run again.

You can not "attach" a SASS/SCSS file to an HTML document.

SASS/SCSS is a CSS preprocessor that runs on the server and compiles to CSS code that your browser understands.

There are client-side alternatives to SASS that can be compiled in the browser using javascript such as LESS CSS, though I advise you compile to CSS for production use.

It's as simple as adding 2 lines of code to your HTML file.

<link rel="stylesheet/less" type="text/css" href="styles.less" />
<script src="less.js" type="text/javascript"></script>

Just add to the CommandArgument parameter and read it out on the Click handler:

<asp:LinkButton ID="ENameLinkBtn" runat="server" 
    style="font-weight: 700; font-size: 8pt;" CommandArgument="YourValueHere" 
    OnClick="ENameLinkBtn_Click" >

Then in your click event:

protected void ENameLinkBtn_Click(object sender, EventArgs e)
{
    LinkButton btn = (LinkButton)(sender);
    string yourValue = btn.CommandArgument;
    // do what you need here
}   

Also you can set the CommandArgument argument when binding if you are using the LinkButton in any bindable controls by doing:

CommandArgument='<%# Eval("SomeFieldYouNeedArguementFrom") %>'

Try this, will make the background animated worked on web but hybrid mobile app not working

backdrop-filter

Unfortunately Mozilla has really dropped the ball and taken it's time with the feature. I'm personally hoping it makes it in to the next Firefox ESR as that is what the next major version of Waterfox will use.

MDN (Mozilla Developer Network) article: https://developer.mozilla.org/en-US/docs/Web/CSS/backdrop-filter

Mozilla implementation: https://bugzilla.mozilla.org/show_bug.cgi?id=1178765

From the MDN documentation page:

/* URL to SVG filter */
backdrop-filter: url(commonfilters.svg#filter);

/* <filter-function> values */
backdrop-filter: blur(2px);
backdrop-filter: brightness(60%);
backdrop-filter: contrast(40%);
backdrop-filter: drop-shadow(4px 4px 10px blue);
backdrop-filter: grayscale(30%);
backdrop-filter: hue-rotate(120deg);
backdrop-filter: invert(70%);
backdrop-filter: opacity(20%);
backdrop-filter: sepia(90%);
backdrop-filter: saturate(80%);

/* Multiple filters */
backdrop-filter: url(filters.svg#filter) blur(4px) saturate(150%);

HashMap<String, String> meMap=new HashMap<String, String>();
meMap.put("Color1","Red");
meMap.put("Color2","Blue");
meMap.put("Color3","Green");
meMap.put("Color4","White");
Iterator iterator = meMap.keySet().iterator();
while( iterator. hasNext() ){
    Toast.makeText(getBaseContext(), meMap.get(iterator.next().toString()), 
    Toast.LENGTH_SHORT).show();
}

You should write a kind of template into the @RequestMapping:

http://localhost:8080/userGrid?_search=${search}&nd=${nd}&rows=${rows}&page=${page}&sidx=${sidx}&sord=${sord}

Now define your business method like following:

@RequestMapping("/userGrid?_search=${search}&nd=${nd}&rows=${rows}&page=${page}&sidx=${sidx}&sord=${sord}")
public @ResponseBody GridModel getUsersForGrid(
@RequestParam(value = "search") String search, 
@RequestParam(value = "nd") int nd, 
@RequestParam(value = "rows") int rows, 
@RequestParam(value = "page") int page, 
@RequestParam(value = "sidx") int sidx, 
@RequestParam(value = "sort") Sort sort) {
...............
}

So, framework will map ${foo} to appropriate @RequestParam.

Since sort may be either asc or desc I'd define it as a enum:

public enum Sort {
    asc, desc
}

Spring deals with enums very well.

This answer is for those seeking to just change the value of a data-attribute

The suggested will not change the value of your Jquery data-attr correctly as @adeneo has stated. For some reason though, I'm not seeing him (or any others) post the correct method for those seeking to update their data-attr. The answer that @Lucas Willems has posted may be the answer to problem Brian Tompsett - ??? is having, but it's not the answer to the inquiry that may be bringing other users here.

Quick answer in regards to original inquiry statement

-To update data-attr

$('#ElementId').attr('data-attributeTitle',newAttributeValue);

Easy mistakes* - there must be "data-" at the beginning of your attribute you're looking to change the value of.

I use named action instead of javascript because javascript often is disabled, and if it isn't it gives a warning.

My web application creates a postscript file that then is converted with ghostscript to a pdf. I want it to print automatically because the user has already clicked on print inside my application. With the information about named actions from @DSimon above, I researched how to solve this. It all boils down to insert the string /Type /Action /S /Named /N /Print at the right place in the pdf.

I was thinking of writing a small utility, but it has to parse the pdf to find the root node, insert /OpenAction with a reference an object with the action, and recalculate the byte-offsets in xref.

But then I found out about pdfmark which is an extension to postscript to express, in postscript syntax, idioms that are converted to pdf by Adobes distiller or by ghostscript.

Since I'm already using ghostscript, all I have to do is append the following to the end of my postscript file:

%AUTOPRINT
[ /_objdef {PrintAction} /type /dict /OBJ pdfmark
[ {PrintAction} << /Type /Action /S /Named /N /Print >> /PUT pdfmark
[ {Catalog} << /OpenAction {PrintAction} >> /PUT pdfmark

and ghostscript will create the action, link it, and calculate the xref offsets. (In postscript % is a comment and PrintAction is my name for the object)

By looking at the PDF I see that it has created this:

1 0 obj
<</Type /Catalog /Pages 3 0 R
/OpenAction  9 0 R
/Metadata 10 0 R
>>
endobj

9 0 obj
<</S/Named
/Type/Action
/N/Print>>endobj

1 0 is object 1, revision 0, and 9 0 is object 9, revision 0. In the pdf-trailer is says that it is object 1 that is the root node. As you can see there is a reference from object 1, /OpenAction to run object 9 revision 0.

With ghostscript it's possible to convert a pdf to postscript (pdf2ps), append the text above, and convert it back to pdf with ps2pdf. It should be noted that meta-information about the pdf is lost in this conversion. I haven't searched more into this.

This is for newer version of Hadoop (I am running 2.4.0)

• In this case stop the cluster sbin/stop-all.sh
• Then go to /etc/hadoop for config files.

In the file: hdfs-site.xml Look out for directory paths corresponding to dfs.namenode.name.dir dfs.namenode.data.dir

• Delete both the directories recursively (rm -r).
• Now format the namenode via bin/hadoop namenode -format
• And finally sbin/start-all.sh

Hope this helps.

Look at the Identity of the Application Pool that's running your application. By default it will be the Network Service account, but you can change this.

At least that's how it works on 2003 server, don't know if some details have changed for 2008 server.

                </div>
                <div class="img-thumbnail  text-center">
                    <img src="@if(isset($product)) {{asset('storage/'.$product->thumbnail)}} @else {{asset('images/no-thumbnail.jpeg')}} @endif" id="imgthumbnail" class="img-fluid" alt="">
                </div>
            </li>
<script>
$(function(){
$('#thumbnail').on('change', function() {
    var file = $(this).get(0).files;
    var reader = new FileReader();
    reader.readAsDataURL(file[0]);
    reader.addEventListener("load", function(e) {
    var image = e.target.result;
$("#imgthumbnail").attr('src', image);
});
});
}
</script>

You can use this code line in view(form)

 <?= $form->field($model, 'hidden1')->hiddenInput(['value'=>'your_value'])->label(false) ?>

Please refere this as example

If your need to pass currant date and time as hidden input : Model attribute is 'created_on' and its value is retrieve from date('Y-m-d H:i:s') , just like:"2020-03-10 09:00:00"

  <?= $form->field($model, 'created_on')->hiddenInput(['value'=>date('Y-m-d H:i:s')])->label(false) ?>

Your question answers itself ;) If og_date contains the date, it's probably a string, so og_date.value is undefined.

Simply use og_date.split('-') instead of og_date.value.split('-')

dependencies {
    compile 'com.android.support:support-v4:19.1.+'
    compile fileTree(dir: 'libs', include: ['*.jar'])
}

This gets conflicted if you have the support jar in your libs folder. If you have the support jar in your project libs folder and you have the module dependency added to compile 'com.android.support:support-v4:13.0.+' the UNEXPECTED_TOPLEVEL_DEPENDANCY exception will be thrown.

Some pages may require more than login/pass. There may even be hidden fields. The most reliable way is to use inspect tool and look at the network tab while logging in, to see what data is being passed on.

Go to the chosen directory and execute:

$ du -d 1 -h

where:

-d 1 is the depth of the directories

-h is the human-readable option

You'll see like that:

0   ./proc
8.5M    ./run
0   ./sys
56M ./etc
12G ./root
33G ./var
23M ./tmp
3.2G    ./usr
154M    ./boot
26G ./home
0   ./media
0   ./mnt
421M    ./opt
0   ./srv
2.6G    ./backups
80G .

...but the form is not submitted with any of the POST data it is supposed to include.

Correct. Disabled form element names/values will not be sent to the server. You should set them as readonly elements.

Also, anchors cannot be disabled like that. You will need to either remove their HREFs (not recommended) or prevent their default behaviour (better way), e.g.:

<script type="text/javascript">
$(document).ready(function(){
    $("form#my_form").submit(function(){
      $('input').attr('readonly', true);
      $('input[type=submit]').attr("disabled", "disabled");
      $('a').unbind("click").click(function(e) {
          e.preventDefault();
          // or return false;
      });
    });
</script>

My problem is possibly due to the hash got wrongly generated by the openssl itself, if anyone is facing similar problem using the method provided by the facebook android guide itself.

One way to deal with this is :

1. Get your sha1 using this tool :

keytool -exportcert -keystore path-to-debug-or-production-keystore -list -v

2. convert it to base64 using this tool

This isn't really recommended, but you can do it all inline like so:

<a href="#" onClick="function test(){ /* Do something */  } test(); return false;"></a>

But I can't think of any situations off hand where this would be better than writing the function somewhere else and invoking it onClick.

To rebase the current local tracker branch moving local changes on top of the latest remote state:

$ git fetch && git rebase

More generally, to fast-forward and drop the local changes (hard reset)*:

$ git fetch && git checkout ${the_branch_name} && git reset --hard origin/${the_branch_name}

to fast-forward and keep the local changes (rebase):

$ git fetch && git checkout ${the_branch_name} && git rebase origin/${the_branch_name}

* - to undo the change caused by unintentional hard reset first do git reflog, that displays the state of the HEAD in reverse order, find the hash the HEAD was pointing to before the reset operation (usually obvious) and hard reset the branch to that hash.

This is adapted from Tono Nam's accepted answer correcting a few wrong measurements in it.

The test:

    LinkedListPerformance.AddLast_LinkedList(); // 32 ms

    LinkedListPerformance.Enumerate_List(); // 1.08 ms
    LinkedListPerformance.Enumerate_LinkedList(); // 3.4 ms

    //I tried below as fun exercise - not very meaningful, see code
    //sort of equivalent to insertion when having the reference to middle node

    LinkedListPerformance.AddMiddle_List(); // 5724 ms
    LinkedListPerformance.AddMiddle_LinkedList1(); // 36 ms
    LinkedListPerformance.AddMiddle_LinkedList2(); // 32 ms

            for (var i = start; i < end; i++)
            {
                if (list.Count == 0)
                    list.AddLast(temp(i));
                else
                {
                    watch.Stop();
                    var curNode = list.First;
                    for (var j = 0; j < list.Count / 2; j++)
                        curNode = curNode.Next;
                    watch.Start();

                    list.AddBefore(curNode, temp(i));
                }
            }

            watch.StopAndPrint();
        }
    }
}

You can see the results are in accordance with theoretical performance others have documented here. Quite clear - LinkedList<T> gains big time in case of insertions. I haven't tested for removal from the middle of list, but the result should be the same. Of course List<T> has other areas where it performs way better like O(1) random access.

DISTINCT is not a function that applies only to some columns. It's a query modifier that applies to all columns in the select-list.

That is, DISTINCT reduces rows only if all columns are identical to the columns of another row.

DISTINCT must follow immediately after SELECT (along with other query modifiers, like SQL_CALC_FOUND_ROWS). Then following the query modifiers, you can list columns.

• RIGHT: SELECT DISTINCT foo, ticket_id FROM table...

  Output a row for each distinct pairing of values across ticket_id and foo.

• WRONG: SELECT foo, DISTINCT ticket_id FROM table...

  If there are three distinct values of ticket_id, would this return only three rows? What if there are six distinct values of foo? Which three values of the six possible values of foo should be output?
  It's ambiguous as written.

Here is a more literal answer (parent window as opposed to opener) to the original question that can be used within an iframe, assuming the domain name in the iframe matches that of the parent window:

You can make a plain controller file like

php artisan make:controller --plain <controller name>

To see all tables:

To see a particular table:

Your main() method is static, but it is referencing two non-static members: con2 and getConnectionUrl2(). You need to do one of three things:

1) Make con2 and getConnectionUrl2() static.

2) Inside main(), create an instance of class testconnect and access con2 and getConnectionUrl2() off of that.

3) Break out a different class to hold con2 and getConnectionUrl2() so that testconnect only has main in it. It will still need to instantiate the different class and call the methods off that.

Option #3 is the best option. #1 is the worst.

But, you cannot access non-static members from within a static method.

That is called a shebang, it tells the shell what program to interpret the script with, when executed.

In your example, the script is to be interpreted and run by the bash shell.

Some other example shebangs are:

(From Wikipedia)

#!/bin/sh — Execute the file using sh, the Bourne shell, or a compatible shell
#!/bin/csh — Execute the file using csh, the C shell, or a compatible shell
#!/usr/bin/perl -T — Execute using Perl with the option for taint checks
#!/usr/bin/php — Execute the file using the PHP command line interpreter
#!/usr/bin/python -O — Execute using Python with optimizations to code
#!/usr/bin/ruby — Execute using Ruby

and a few additional ones I can think off the top of my head, such as:

#!/bin/ksh
#!/bin/awk
#!/bin/expect

In a script with the bash shebang, for example, you would write your code with bash syntax; whereas in a script with expect shebang, you would code it in expect syntax, and so on.

Response to updated portion:

It depends on what /bin/sh actually points to on your system. Often it is just a symlink to /bin/bash. Sometimes portable scripts are written with #!/bin/sh just to signify that it's a shell script, but it uses whichever shell is referred to by /bin/sh on that particular system (maybe it points to /bin/bash, /bin/ksh or /bin/zsh)

These do the same thing:

window.location.assign(url);
window.location = url;
window.location.href = url;

They simply navigate to the new URL. The replace method on the other hand navigates to the URL without adding a new record to the history.

So, what you have read in those many forums is not correct. The assign method does add a new record to the history.

This is the same as monoxide's answer, but a bit more concise.

If you're looking for a document-level key event handling, then binding it during componentDidMount is the best way (as shown by Brad Colthurst's codepen example):

class ActionPanel extends React.Component {
  constructor(props){
    super(props);
    this.escFunction = this.escFunction.bind(this);
  }
  escFunction(event){
    if(event.keyCode === 27) {
      //Do whatever when esc is pressed
    }
  }
  componentDidMount(){
    document.addEventListener("keydown", this.escFunction, false);
  }
  componentWillUnmount(){
    document.removeEventListener("keydown", this.escFunction, false);
  }
  render(){
    return (   
      <input/>
    )
  }
}

Note that you should make sure to remove the key event listener on unmount to prevent potential errors and memory leaks.

EDIT: If you are using hooks, you can use this useEffect structure to produce a similar effect:

const ActionPanel = (props) => {
  const escFunction = useCallback((event) => {
    if(event.keyCode === 27) {
      //Do whatever when esc is pressed
    }
  }, []);

  useEffect(() => {
    document.addEventListener("keydown", escFunction, false);

    return () => {
      document.removeEventListener("keydown", escFunction, false);
    };
  }, []);

  return (   
    <input />
  )
};

This should work:

s=json.dumps(variables)
variables2=json.loads(s)
assert(variables==variables2)

renderItem(item)
  {
    const width = '80%';
    var items = [];

    for(let i = 0; i < item.count; i++){

        items.push( <View style={{ padding: 10, borderBottomColor: "#f2f2f2", borderBottomWidth: 10, flexDirection: 'row' }}>
    <View style={{ width }}>
      <Text style={styles.name}>{item.title}</Text>
      <Text style={{ color: '#818181', paddingVertical: 10 }}>{item.taskDataElements[0].description + " "}</Text>
      <Text style={styles.begin}>BEGIN</Text>
    </View>

    <Text style={{ backgroundColor: '#fcefec', padding: 10, color: 'red', height: 40 }}>{this.msToTime(item.minTatTimestamp) <= 0 ? "NOW" : this.msToTime(item.minTatTimestamp) + "hrs"}</Text>
  </View> )
  }

  return items;
}

render() {
return (this.renderItem(this.props.item)) 
}

I was getting similar error while creating web-app in eclipse and resolved the problem just by cleaning (deleting all files from) and rebuilding the maven repository

In my case issue was that numberOfRowsInSection was returning similar number of rows after calling tableView.deleteRows(...).

Since this was the required behaviour in my case, I ended up calling tableView.reloadData() instead of tableView.deleteRows(...) in cases where numberOfRowsInSection will remain same after deleting a row.

My numeric control:

function CheckNumeric(event) {
    var _key = (window.Event) ? event.which : event.keyCode;
    if (_key > 95 && _key < 106) {
        return true;
    }
    else if (_key > 47 && _key < 58) {
        return true;
    }
    else {
        return false;
    }
}

<input type="text" onkeydown="return CheckNumerick(event);" />

try it

BackSpace key code is 8

One place the parentheses suggestion fails is if say both numbers are HTML input variables. Say a and b are variables and one receives their values as follows (I am no HTML expert but my son ran into this and there was no parentheses solution i.e.

• HTML inputs were intended numerical values for variables a and b, so say the inputs were 2 and 3.
• Following gave string concatenation outputs: a+b displayed 23; +a+b displayed 23; (a)+(b) displayed 23;
• From suggestions above we tried successfully : Number(a)+Number(b) displayed 5; parseInt(a) + parseInt(b) displayed 5.

Thanks for the help just an FYI - was very confusing and I his Dad got yelled at 'that is was Blogger.com's fault" - no it's a feature of HTML input default combined with the 'addition' operator, when they occur together, the default left-justified interpretation of all and any input variable is that of a string, and hence the addition operator acts naturally in its dual / parallel role now as a concatenation operator since as you folks explained above it is left-justification type of interpretation protocol in Java and Java script thereafter. Very interesting fact. You folks offered up the solution, I am adding the detail for others who run into this.

The ISO 8601 time format does not store a time zone name, only the corresponding UTC offset is preserved.

To convert a file ctime to an ISO 8601 time string while preserving the UTC offset in Python 3:

>>> import os
>>> from datetime import datetime, timezone
>>> ts = os.path.getctime(some_file)
>>> dt = datetime.fromtimestamp(ts, timezone.utc)
>>> dt.astimezone().isoformat()
'2015-11-27T00:29:06.839600-05:00'

The code assumes that your local timezone is Eastern Time Zone (ET) and that your system provides a correct UTC offset for the given POSIX timestamp (ts), i.e., Python has access to a historical timezone database on your system or the time zone had the same rules at a given date.

If you need a portable solution; use the pytz module that provides access to the tz database:

>>> import os
>>> from datetime import datetime
>>> import pytz  # pip install pytz
>>> ts = os.path.getctime(some_file)
>>> dt = datetime.fromtimestamp(ts, pytz.timezone('America/New_York'))
>>> dt.isoformat()
'2015-11-27T00:29:06.839600-05:00'

The result is the same in this case.

If you need the time zone name/abbreviation/zone id, store it separately.

>>> dt.astimezone().strftime('%Y-%m-%d %H:%M:%S%z (%Z)')
'2015-11-27 00:29:06-0500 (EST)'

Note: no, : in the UTC offset and EST timezone abbreviation is not part of the ISO 8601 time format. It is not unique.

Different libraries/different versions of the same library may use different time zone rules for the same date/timezone. If it is a future date then the rules might be unknown yet. In other words, the same UTC time may correspond to a different local time depending on what rules you use -- saving a time in ISO 8601 format preserves UTC time and the local time that corresponds to the current time zone rules in use on your platform. You might need to recalculate the local time on a different platform if it has different rules.

I don't know much about jQuery, but try this:

row_id = "#5";
row = $("body").find(row_id);

Edit: Of course, if the variable is a number, you have to add "#" to the front:

row_id = 5
row = $("body").find("#"+row_id);

I think you're confused about what binary is. Binary and decimal are just different representations of a number - e.g. 101 base 2 and 5 base 10 are the same number. The operations add, subtract, and compare operate on numbers - 101 base 2 == 5 base 10 and addition is the same logical operation no matter what base you're working in. The fact that your python interpreter may store things as binary internally doesn't affect how you work with it - if you have an integer type, just use +, -, etc.

If you have strings of binary digits, you'll have to either write your own implementation or convert them using the int(binaryString, 2) function.

Starting with Node.js version 13 you can take advantage of ES6 Modules.

export function foo() {
    return 'foo';
}

export function bar() {
    return foo();
}

Following the Class approach:

class MyClass {

    foo() {
        return 'foo';
    }

    bar() {
        return this.foo();
    }
}

module.exports = new MyClass();

This will instantiate the class only once, due to Node's module caching:
https://nodejs.org/api/modules.html#modules_caching

Try browse the WCF in IIS see if it's alive and works normally,

In my case it's because the physical path of the WCF is misdirected.

How about this?

for item in mylist:
    if item in checklist:
        pass
    else:
       # do something
       print item

@HostListener is a decorator for the callback/event handler method, so remove the ; at the end of this line:

@HostListener('click', ['$event.target']);

Here's a working plunker that I generated by copying the code from the API docs, but I put the onClick() method on the same line for clarity:

import {Component, HostListener, Directive} from 'angular2/core';

@Directive({selector: 'button[counting]'})
class CountClicks {
  numberOfClicks = 0;
  @HostListener('click', ['$event.target']) onClick(btn) {
    console.log("button", btn, "number of clicks:", this.numberOfClicks++);
  }
}
@Component({
  selector: 'my-app',
  template: `<button counting>Increment</button>`,
  directives: [CountClicks]
})
export class AppComponent {
  constructor() { console.clear(); }
}

Host binding can also be used to listen to global events:

To listen to global events, a target must be added to the event name. The target can be window, document or body (reference)

@HostListener('document:keyup', ['$event'])
handleKeyboardEvent(kbdEvent: KeyboardEvent) { ... }

In our case, the Windows service account that SQL Server and SQL Agent were running under were locked out in Active Directory.

For MacOS Mojave running MySQL 5.6.23 I had this problem with writing files, but not loading them. (Not seen with previous versions of Mac OS). As most of the answers to this question have been for other systems, I thought I would post the my.cnf file that cured this (and a socket problems too) in case it is of help to other Mac users. This is /etc/my.cnf

[client]
default-character-set=utf8

[mysqld]
character-set-server=utf8
secure-file-priv = ""
skip-external-locking

(The internationalization is irrelevant to the question.)

Nothing else required. Just turn the MySQL server off and then on again in Preferences (we are talking Mac) for this to take.

Do not use a union!

C++ does not permit type punning via unions!
Reading from a union field that was not the last field written to is undefined behaviour!
Many compilers support doing so as an extensions, but the language makes no guarantee.

See this answer for more details:

https://stackoverflow.com/a/11996970

There are only two valid answers that are guaranteed to be portable.

The first answer, if you have access to a system that supports C++20,
is to use std::endian from the <type_traits> header.

(At the time of writing, C++20 has not yet been released, but unless something happens to affect std::endian's inclusion, this shall be the preferred way to test the endianness at compile time from C++20 onwards.)

C++20 Onwards

constexpr bool is_little_endian = (std::endian::native == std::endian::little);

Prior to C++20, the only valid answer is to store an integer and then inspect its first byte through type punning.
Unlike the use of unions, this is expressly allowed by C++'s type system.

It's also important to remember that for optimum portability static_cast should be used,
because reinterpret_cast is implementation defined.

If a program attempts to access the stored value of an object through a glvalue of other than one of the following types the behavior is undefined: ... a char or unsigned char type.

C++11 Onwards

enum class endianness
{
    little = 0,
    big = 1,
};

inline endianness get_system_endianness()
{
    const int value { 0x01 };
    const void * address = static_cast<const void *>(&value);
    const unsigned char * least_significant_address = static_cast<const unsigned char *>(address);
    return (*least_significant_address == 0x01) ? endianness::little : endianness::big;
}

C++11 Onwards (without enum)

inline bool is_system_little_endian()
{
    const int value { 0x01 };
    const void * address = static_cast<const void *>(&value);
    const unsigned char * least_significant_address = static_cast<const unsigned char *>(address);
    return (*least_significant_address == 0x01);
}

C++98/C++03

inline bool is_system_little_endian()
{
    const int value = 0x01;
    const void * address = static_cast<const void *>(&value);
    const unsigned char * least_significant_address = static_cast<const unsigned char *>(address);
    return (*least_significant_address == 0x01);
}

It means that trackDAO should not be serialized.

simplify the whole thing a bit, fix some issues with commas which will blow up some browsers:

  $(document).ready(function () {
       $("#register").validate({
           debug: true,
           rules: {
               year: {
                   required: function () {
                       return ($("#year option:selected").val() == "0");
                   }
               }
           },
           messages: {
               year: "Year Required"
           }
       });
   });

Jumping to an assumption, should your select not have this attribute validate="required:true"?

This answer below shows another method using "regexp feature of the Description Setter Plugin" which solved my problem as I could not install new plugins on Jenkins due to permission issues:

Use build timestamp in setting build description Jenkins

METHOD1->

Since origin already exist remove it.

git remote rm origin
git remote add origin https://github.com/USERNAME/REPOSITORY.git

METHOD2->

One can also change existing remote repository URL by ->git remote set-url

If you're updating to use HTTPS

git remote set-url origin https://github.com/USERNAME/REPOSITORY.git

If you're updating to use SSH

git remote set-url origin [email protected]:USERNAME/REPOSITORY.git

If trying to update a remote that doesn't exist you will receive a error. So be careful of that.

METHOD3->

Use the git remote rename command to rename an existing remote. An existing remote name, for example, origin.

git remote rename origin startpoint
# Change remote name from 'origin' to 'startpoint'

To verify remote's new name->

git remote -v

If new to Git try this tutorial->

In the manual (https://angular.io/guide/http) I read: The HttpHeaders class is immutable, so every set() returns a new instance and applies the changes.

The following code works for me with angular-4:

 return this.http.get(url, {headers: new HttpHeaders().set('UserEmail', email ) });

My favorite approach, without external libraries:

try {
    URI uri = new URI(name);

    // perform checks for scheme, authority, host, etc., based on your requirements

    if ("mailto".equals(uri.getScheme()) {/*Code*/}
    if (uri.getHost() == null) {/*Code*/}

} catch (URISyntaxException e) {
}

The way to do this in 2019+ is to use DeviceOrientation API. This works in most modern browsers on desktop and mobile.

window.addEventListener("deviceorientation", handleOrientation, true);

After registering your event listener (in this case, a JavaScript function called handleOrientation()), your listener function periodically gets called with updated orientation data.

The orientation event contains four values:

• DeviceOrientationEvent.absolute
• DeviceOrientationEvent.alpha
• DeviceOrientationEvent.beta
• DeviceOrientationEvent.gamma

The event handler function can look something like this:

function handleOrientation(event) {
  var absolute = event.absolute;
  var alpha    = event.alpha;
  var beta     = event.beta;
  var gamma    = event.gamma;
  // Do stuff with the new orientation data
}

As mentioned in other answers, you can use the --filter option to limit the installed packages:

android update sdk --filter ...

The other answers don't mention that you can use constant string identifiers instead of indexes (which will change) for the filter options. This is helpful for unattended or scripted installs. Man for --filter option:

... This also accepts the identifiers returned by 'list sdk --extended'.

android list sdk --all --extended :

Packages available for installation or update: 97
----------
id: 1 or "tools"
     Type: Tool
     Desc: Android SDK Tools, revision 22.6.2
----------
id: 2 or "platform-tools"
     Type: PlatformTool
     Desc: Android SDK Platform-tools, revision 19.0.1
----------
id: 3 or "build-tools-19.0.3"
     Type: BuildTool
     Desc: Android SDK Build-tools, revision 19.0.3

Then you can use the string ids as the filter options to precisely specify the versions you want:

android update sdk --filter tools,platform-tools,build-tools-19.0.3 etc

SELECT only retrieves data from the database, it does not change the table itself.

If you write

SELECT a AS b FROM x

"b" is just an alias name in the query. It does not create an extra column. Your result in the example would only contain one column named "b". But the column in the table would stay "a". "b" is just another name.

I don't really understand what you mean with "so I can use it with each item later on". Do you mean later in the select statement or later in your application. Perhaps you could provide some example code.

    });

});

I claim that the obvious way to see whether casting a value changed the value would be to cast and check the result. I would, however, remove the unnecessary cast when comparing. I'm also not too keen on one letter variable names (exception x and y, but not when they mean row and column (sometimes respectively)).

public static int intValue(long value) {
    int valueInt = (int)value;
    if (valueInt != value) {
        throw new IllegalArgumentException(
            "The long value "+value+" is not within range of the int type"
        );
    }
    return valueInt;
}

However, really I would want to avoid this conversion if at all possible. Obviously sometimes it's not possible, but in those cases IllegalArgumentException is almost certainly the wrong exception to be throwing as far as client code is concerned.

In my case, Web Sharing was running, which blocked XAMPP.

'Untick' Web Sharing in the Bluetooth Settings (or Network), which causes HTTPD to show in activity log.

Apache should now run and be available!

Try it:

public static String print(byte[] bytes) {
    StringBuilder sb = new StringBuilder();
    sb.append("[ ");
    for (byte b : bytes) {
        sb.append(String.format("0x%02X ", b));
    }
    sb.append("]");
    return sb.toString();
}

Example:

 public static void main(String []args){
    byte[] bytes = new byte[] { 
        (byte) 0x01, (byte) 0xFF, (byte) 0x2E, (byte) 0x6E, (byte) 0x30
    };

    System.out.println("bytes = " + print(bytes));
 }

Output: bytes = [ 0x01 0xFF 0x2E 0x6E 0x30 ]

More specifically:

1. Run Server Manager (on task bar and start menu)
2. Choose the server to administer (probably local server)
3. Scroll down to "Roles and Features" section.
4. Choose "Add Role or Feature" from Tasks drop down
5. On "Add Role or Feature Wizard" dialog, click down to "Features" in list of pages on the left.
6. Expand ".Net 3.5" or ".Net 4.5", depending on what you have installed. (you can go back up to "roles" screen to add if you don't have.
7. Under "WCF Services", check the box for "HTTP-Activation". You can also add non-http types if you know you need them (tcp, named pipes, etc).
8. Click "Install" Button.

In my case i was getting this when switched the Minimum target version of the android and when i changed back to original one (when i created project at first). So for that uninstalling worked. But when i changed my android version to latest i was getting it again. To fix that, i went to properties of android project and in Android manifest section, i added a package name e.g com.dotnetdreamer.net. If you have already a package name then you can simply rename it to something else.

      "esnext",
      "es6",
],

This workaround solved the problem (my sample code):

Interface:

   interface TxBacklog {
      status: string,
      txHash: string,
   }

State variable:

    const [txBacklog, setTxBacklog] = React.useState<TxBacklog[]>();

Push new object into array:

    // Define new object to be added
    const newTx = {
       txHash: '0x368eb7269eb88ba86..',
       status: 'pending'
    };
    // Push new object into array
    (txBacklog) 
       ? setTxBacklog(prevState => [ ...prevState!, newTx ])
       : setTxBacklog([newTx]);

In WPF the titlebar is part of the non-client area, which can't be modified through the WPF window class. You need to manipulate the Win32 handles (if I remember correctly).
This article could be helpful for you: Custom Window Chrome in WPF.

Let's say the list is:

<ul>
 <li>item1</li>
 <li>item2</li>
 <li>item3</li>
</ul>

For this example. If I understand correctly, you want the list items to be in the middle of the screen, but you want the text IN those list items to be centered to the left of the list item itself. Doing that is actually pretty easy. You just need some CSS:

ul {
    display: table; 
    margin: 0 auto;
    text-align: left;
}

And it works! Here is what is happening. First, we say we want to affect only unordered lists. Then, we do Rafael Herscovici's trick for centering the list items. Finally, we say to align the text to the left of the list items.

After executing the below regex, your answer is in the first capture.

/^(.*?)\.txt/

INSERT statements that use VALUES syntax can insert multiple rows. To do this, include multiple lists of column values, each enclosed within parentheses and separated by commas.

Example:

INSERT INTO tbl_name (a,b,c) VALUES(1,2,3),(4,5,6),(7,8,9);

Use the

Request.Form[]

for POST variables,

Request.QueryString[]

for GET.

Since the introduction of Visual Studio 2015, this location has changed and is added into your solution root under the following location:

C:\<Path\To\Solution>\.vs\config\applicationhost.config

I hope this saves you some time!

I create a function that return boolean type:

export const isSafari = () => navigator.userAgent.toLowerCase().indexOf('safari') !== -1

The WordPress password hasher implements the Portable PHP password hashing framework, which is used in Content Management Systems like WordPress and Drupal.

They used to use MD5 in the older versions, but sadly for me, no more. You can generate hashes using this encryption scheme at http://scriptserver.mainframe8.com/wordpress_password_hasher.php.

Create a Bash (tools.sh) to select a serial from devices (or emulator):

clear;
echo "====================================================================================================";
echo " ADB DEVICES";
echo "====================================================================================================";
echo "";

adb_devices=( $(adb devices | grep -v devices | grep device | cut -f 1)#$(adb devices | grep -v devices | grep device | cut -f 2) );

if [ $((${#adb_devices[@]})) -eq "1" ] && [ "${adb_devices[0]}" == "#" ]
then
    echo "No device found";
    echo ""; 
    echo "====================================================================================================";
    device=""
    // Call Main Menu function fxMenu;
else
    read -p "$(
        f=0
        for dev in "${adb_devices[@]}"; do
            nm="$(echo ${dev} | cut -f1 -d#)";
            tp="$(echo ${dev} | cut -f2 -d#)";
            echo " $((++f)). ${nm} [${tp}]";
        done

        echo "";
        echo " 0. Quit"
        echo "";

        echo "====================================================================================================";
        echo "";
        echo ' Please select a device: '
    )" selection

    error="You think it's over just because I am dead. It's not over. The games have just begun.";
    // Call Validation Numbers fxValidationNumberMenu ${#adb_devices[@]} ${selection} "${error}" 
    case "${selection}" in
        0)
            // Call Main Menu function fxMenu;
        *)  
            device="$(echo ${adb_devices[$((selection-1))]} | cut -f1 -d#)";
            // Call Main Menu function fxMenu;
    esac
fi

Then in another option can use adb -s (global option -s use device with given serial number that overrides $ANDROID_SERIAL):

adb -s ${device} <command>

I tested this code on MacOS terminal, but I think it can be used on windows across Git Bash Terminal.

Also remember configure environmental variables and Android SDK paths on .bash_profile file:

export ANDROID_HOME="/usr/local/opt/android-sdk/"
export PATH="$ANDROID_HOME/platform-tools:$PATH"
export PATH="$ANDROID_HOME/tools:$PATH"

you can write a stored procedure like this:

CREATE PROCEDURE sanitize_TABLE()

BEGIN

#replace space with underscore

UPDATE Table SET FieldName = REPLACE(FieldName," ","_") WHERE FieldName is not NULL;

#delete dot

UPDATE Table SET FieldName = REPLACE(FieldName,".","") WHERE FieldName is not NULL;

#delete (

UPDATE Table SET FieldName = REPLACE(FieldName,"(","") WHERE FieldName is not NULL;

#delete )

UPDATE Table SET FieldName = REPLACE(FieldName,")","") WHERE FieldName is not NULL;

#raplace or delete any char you want

#..........................

END

In this way you have modularized control over table.

You can also generalize stored procedure making it, parametric with table to sanitoze input parameter

If you're using Homebrew /usr/local/bin should already be at the front of $PATH or at least come before /usr/bin. If you now run brew link --force openssl in your terminal window, open a new one and run which openssl in it. It should now show openssl under /usr/local/bin.

I had this issue, I logged in as administrator and it fixed the issue.

As a rule passing by const reference is better. But if you need to modify you function argument locally you should better use passing by value. For some basic types the performance in general the same both for passing by value and by reference. Actually reference internally represented by pointer, that is why you can expect for instance that for pointer both passing are the same in terms of performance, or even passing by value can be faster because of needless dereference.

I've updated the great utility jenv to make it easy to setup on macOS.

According to this MSDN blog: https://blogs.msdn.microsoft.com/manishagarwal/2005/09/28/resolving-file-references-in-team-build-part-2/

There is a search order for assemblies when building. The search order is as follows:

• Files from the current project – indicated by ${CandidateAssemblyFiles}.
• $(ReferencePath) property that comes from .user/targets file.
• %(HintPath) metadata indicated by reference item.
• Target framework directory.
• Directories found in registry that uses AssemblyFoldersEx Registration.
• Registered assembly folders, indicated by ${AssemblyFolders}.
• $(OutputPath) or $(OutDir)
• GAC

So, if the desired assembly is found by HintPath, but an alternate assembly can be found using ReferencePath, it will prefer the ReferencePath'd assembly to the HintPath'd one.

In addition, if you want to refer to the root directory, you can use:

/

Which will refer to the root. So, let's say we're in a file that's nested within a few levels of folders and you want to go back to the main index.html:

<a href="/index.html">My Index Page</a>

Robert is spot-on with further relative path explanations.

Change:

x.length

to:

x.options.length

Link to fiddle

And I agree with Abraham - you might want to use text instead of value

Update
The reason your fiddle didn't work was because you chose the option: "onLoad" instead of: "No wrap - in "

varchar(10) will store 10 characters, which may be more than 10 bytes. In indexes, it will allocate the maximium length of the field - so if you are using UTF8-mb4, it will allocate 40 bytes for the 10 character field.

Like that

var purchCount = (from purchase in myBlaContext.purchases select purchase).Count();

or even easier

var purchCount = myBlaContext.purchases.Count()

use count instead of sum in your original formula u will get your result

Original One

=SUM(IF(MONTH('2013'!$A$2:$A$19)=4,'2013'!$D$2:$D$19,0))

Modified One

=COUNT(IF(MONTH('2013'!$A$2:$A$19)=4,'2013'!$D$2:$D$19,0))

AND USE ctrl+shift+enter TO EXECUTE

You can use the Number.isFinite() function:

Number.isFinite(Infinity);  // false
Number.isFinite(NaN);       // false
Number.isFinite(-Infinity); // false
Number.isFinite('0');       // false
Number.isFinite(null);      // false

Number.isFinite(0);         // true
Number.isFinite(2e64);      // true

Note: there's a significant difference between the global function isFinite() and the latter Number.isFinite(). In the case of the former, string coercion is performed - so isFinite('0') === true whilst Number.isFinite('0') === false.

Also, note that this is not available in IE!

To discover any constraints used, use the code below:

-- Set the long data type for display purposes to 500000.

SET LONG 500000

-- Define a session scope variable.

VARIABLE output CLOB

-- Query the table definition through the <code>DBMS_METADATA</code> package.

SELECT dbms_metadata.get_ddl('TABLE','[Table Described]') INTO :output FROM dual;

This essentially shows a create statement for how the referenced table is made. By knowing how the table is created, you can see all of the table constraints.

Answer taken from Michael McLaughlin's blog: http://michaelmclaughlin.info/db1/lesson-5-querying-data/lab-5-querying-data/ From his Database Design I class.

Below mechanism helps in redirecting multiple lines to file. Keep complete string under " so that we can redirect values of the variable.

#!/bin/bash
kernel="2.6.39"
echo "line 1, ${kernel}
line 2," > a.txt
echo 'line 2, ${kernel}
line 2,' > b.txt

Content of a.txt is

line 1, 2.6.39
line 2,

Content of b.txt is

line 2, ${kernel}
line 2,

Mine got solved by enabling multiDex for debug builds.

defaultConfig {
multiDexEnabled true
}

There is a Date function.

I'm sure there are other ways to accomplish this, but one solution would be to use join through the Query Builder.

If you have tables set up something like this:

users
    id
    ...

friends
    id
    user_id
    friend_id
    ...

votes, comments and status_updates (3 tables)
    id
    user_id
    ....

In your User model:

class User extends Eloquent {
    public function friends()
    {
        return $this->hasMany('Friend');
    }
}

In your Friend model:

class Friend extends Eloquent {
    public function user()
    {
        return $this->belongsTo('User');
    }
}

Then, to gather all the votes for the friends of the user with the id of 1, you could run this query:

$user = User::find(1);
$friends_votes = $user->friends()
    ->with('user') // bring along details of the friend
    ->join('votes', 'votes.user_id', '=', 'friends.friend_id')
    ->get(['votes.*']); // exclude extra details from friends table

Run the same join for the comments and status_updates tables. If you would like votes, comments, and status_updates to be in one chronological list, you can merge the resulting three collections into one and then sort the merged collection.

Edit

To get votes, comments, and status updates in one query, you could build up each query and then union the results. Unfortunately, this doesn't seem to work if we use the Eloquent hasMany relationship (see comments for this question for a discussion of that problem) so we have to modify to queries to use where instead:

$friends_votes = 
    DB::table('friends')->where('friends.user_id','1')
    ->join('votes', 'votes.user_id', '=', 'friends.friend_id');

$friends_comments = 
    DB::table('friends')->where('friends.user_id','1')
    ->join('comments', 'comments.user_id', '=', 'friends.friend_id');

$friends_status_updates = 
    DB::table('status_updates')->where('status_updates.user_id','1')
    ->join('friends', 'status_updates.user_id', '=', 'friends.friend_id');

$friends_events = 
    $friends_votes
    ->union($friends_comments)
    ->union($friends_status_updates)
    ->get();

At this point, though, our query is getting a bit hairy, so a polymorphic relationship with and an extra table (like DefiniteIntegral suggests below) might be a better idea.

Checking it out in python3:

python -V
Python 3.6.5

Example1:

.
+-- parent.py
+-- start.py
+-- sub
    +-- relative.py

- start.py
import sub.relative

- parent.py
print('Hello from parent.py')

- sub/relative.py
from .. import parent

If we run it like this(just to make sure PYTHONPATH is empty):

PYTHONPATH='' python3 start.py

Output:

Traceback (most recent call last):
  File "start.py", line 1, in <module>
    import sub.relative
  File "/python-import-examples/so-example-v1/sub/relative.py", line 1, in <module>
    from .. import parent
ValueError: attempted relative import beyond top-level package

If we change import in sub/relative.py

- sub/relative.py
import parent

If we run it like this:

PYTHONPATH='' python3 start.py

Output:

Hello from parent.py

Example2:

.
+-- parent.py
+-- sub
    +-- relative.py
    +-- start.py

- parent.py
print('Hello from parent.py')

- sub/relative.py
print('Hello from relative.py')

- sub/start.py
import relative
from .. import parent

Run it like:

PYTHONPATH='' python3 sub/start.py

Output:

Hello from relative.py
Traceback (most recent call last):
  File "sub/start.py", line 2, in <module>
    from .. import parent
ValueError: attempted relative import beyond top-level package

If we change import in sub/start.py:

- sub/start.py
import relative
import parent

Run it like:

PYTHONPATH='' python3 sub/start.py

Output:

Hello from relative.py
Traceback (most recent call last):
  File "sub/start.py", line 3, in <module>
    import parent
ModuleNotFoundError: No module named 'parent'

Run it like:

PYTHONPATH='.' python3 sub/start.py

Output:

Hello from relative.py
Hello from parent.py

Also it's better to use import from root folder, i.e.:

- sub/start.py
import sub.relative
import parent

Run it like:

PYTHONPATH='.' python3 sub/start.py

Output:

Hello from relative.py
Hello from parent.py

If I use the following query,

INSERT INTO xx_BLOB(ID,IMAGE) 
VALUES(1,LOAD_FILE('E:/Images/xxx.png'));

Error: no such function: LOAD_FILE

I couldn't find the file in C:\Program Files\Java\jdk1.8.0_261\jre\bin. My sqldeveloper came without jre at all so what it worked for me was copying the file from an older Oracle jre release to C:\Program Files\Java\jdk1.8.0_261\jre\bin.

int i = (int)char.GetNumericValue(c);

Yet another option:

int i = c & 0x0f;

This should accomplish this as well.

I know this is an old thread, but thought I'd put my two cents in. Ternary operators are able to be nested in the following fashion:

var variable = conditionA ? valueA : (conditionB ? valueB: (conditionC ? valueC : valueD));

Example:

var answer = value === 'foo' ? 1 :
    (value === 'bar' ? 2 : 
        (value === 'foobar' ? 3 : 0));

I had the same error when I deployed my app. I've got solution from this site: Component with CLSID XXX failed due to the following error: 80070005 Access is denied

Here is this solution:

1. In DCOMCNFG, right click on the My Computer and select properties.

2. Choose the COM Securities tab.

3. In Access Permissions, click Edit Defaults and add Network Service to it and give it Allow local access permission. Do the same for < Machine_name >\Users.

4. In Launch and Activation Permissions, click Edit Defaults and add Network Service to it and give it Local launch and Local Activation permission. Do the same for < Machine_name >\Users.

*I used forms authentication.

jq '.users[]|.first,.last' | paste - -

You are giving the span a 100% width resulting in it expanding to the size of the parent. This means you can’t center-align it, as there is no room to move it.

You could give the span a set width, then add the margin:0 auto again. This would center-align it.

.left 
{
   background-color: #999999;
   height: 50px;
   width: 24.5%;
}
span.panelTitleTxt 
{
   display:block;
   width:100px;
   height: 100%;
   margin: 0 auto;
}

In this case, you are thinking of the String comparing function "String".equals("some_text"). Chars do not need to use this function. Instead a standard == comparison operator will suffice.

private static int countNumChars(String s) {
    for(char c : s.toCharArray()){
        if (c == ' ') // your resulting outcome
    }
}

Try This , it will call validation for all control in form :

validateAllFormControl(formGroup: FormGroup) {         
  Object.keys(formGroup.controls).forEach(field => {  
    const control = formGroup.get(field);             
    if (control instanceof FormControl) {             
      control.markAsTouched({ onlySelf: true });
    } else if (control instanceof FormGroup) {        
      this.validateAllFormControl(control);            
    }
  });
}

$(this).css('marginBottom').replace('px','')

Object files are codes that are dependent on functions, symbols, and text to run the program. Just like old telex machines, which required teletyping to send signals to other telex machine.

In the same way processor's require binary code to run, object files are like binary code but not linked. Linking creates additional files so that the user does not have to have compile the C language themselves. Users can directly open the exe file once the object file is linked with some compiler like c language , or vb etc.

As of jQuery 1.7, the .on() method is the preferred method for attaching event handlers to a document. For earlier versions, the .bind() method is used for attaching an event handler directly to elements.

$(document).on('mouseover mouseout',".brand", function () {
  $(".star").toggleClass("hovered");
})

Here's a nice way for child objects to have access to parent properties and methods using JavaScript's prototype chain, and it's compatible with Internet Explorer. JavaScript searches the prototype chain for methods and we want the child’s prototype chain to looks like this:

Child instance -> Child’s prototype (with Child methods) -> Parent’s prototype (with Parent methods) -> Object prototype -> null

The child methods can also call shadowed parent methods, as shown at the three asterisks *** below.

Here’s how:

//Parent constructor_x000D_
function ParentConstructor(firstName){_x000D_
    //add parent properties:_x000D_
    this.parentProperty = firstName;_x000D_
}_x000D_
_x000D_
//add 2 Parent methods:_x000D_
ParentConstructor.prototype.parentMethod = function(argument){_x000D_
    console.log(_x000D_
            "Parent says: argument=" + argument +_x000D_
            ", parentProperty=" + this.parentProperty +_x000D_
            ", childProperty=" + this.childProperty_x000D_
    );_x000D_
};_x000D_
_x000D_
ParentConstructor.prototype.commonMethod = function(argument){_x000D_
    console.log("Hello from Parent! argument=" + argument);_x000D_
};_x000D_
_x000D_
//Child constructor    _x000D_
function ChildConstructor(firstName, lastName){_x000D_
    //first add parent's properties_x000D_
    ParentConstructor.call(this, firstName);_x000D_
_x000D_
    //now add child's properties:_x000D_
    this.childProperty = lastName;_x000D_
}_x000D_
_x000D_
//insert Parent's methods into Child's prototype chain_x000D_
var rCopyParentProto = Object.create(ParentConstructor.prototype);_x000D_
rCopyParentProto.constructor = ChildConstructor;_x000D_
ChildConstructor.prototype = rCopyParentProto;_x000D_
_x000D_
//add 2 Child methods:_x000D_
ChildConstructor.prototype.childMethod = function(argument){_x000D_
    console.log(_x000D_
            "Child says: argument=" + argument +_x000D_
            ", parentProperty=" + this.parentProperty +_x000D_
            ", childProperty=" + this.childProperty_x000D_
    );_x000D_
};_x000D_
_x000D_
ChildConstructor.prototype.commonMethod = function(argument){_x000D_
    console.log("Hello from Child! argument=" + argument);_x000D_
_x000D_
    // *** call Parent's version of common method_x000D_
    ParentConstructor.prototype.commonMethod(argument);_x000D_
};_x000D_
_x000D_
//create an instance of Child_x000D_
var child_1 = new ChildConstructor('Albert', 'Einstein');_x000D_
_x000D_
//call Child method_x000D_
child_1.childMethod('do child method');_x000D_
_x000D_
//call Parent method_x000D_
child_1.parentMethod('do parent method');_x000D_
_x000D_
//call common method_x000D_
child_1.commonMethod('do common method');

I could be able to update the environment variable by using the following

string EnvPath = System.Environment.GetEnvironmentVariable("PATH", EnvironmentVariableTarget.Machine) ?? string.Empty;
if (!string.IsNullOrEmpty(EnvPath) && !EnvPath .EndsWith(";"))
    EnvPath = EnvPath + ';';
EnvPath = EnvPath + @"C:\Test";
Environment.SetEnvironmentVariable("PATH", EnvPath , EnvironmentVariableTarget.Machine);

import sys
print(sys.executable)
print(sys.version)
print(sys.version_info)

Install the IPython kernel spec.

optional arguments: -h, --help show this help message and exit --user Install for the current user instead of system-wide --name NAME Specify a name for the kernelspec. This is needed to have multiple IPython kernels at the same time. --display-name DISPLAY_NAME Specify the display name for the kernelspec. This is helpful when you have multiple IPython kernels. --profile PROFILE Specify an IPython profile to load. This can be used to create custom versions of the kernel. --prefix PREFIX Specify an install prefix for the kernelspec. This is needed to install into a non-default location, such as a conda/virtual-env. --sys-prefix Install to Python's sys.prefix. Shorthand for --prefix='/Users/bussonniermatthias/anaconda'. For use in conda/virtual-envs.

Try this:

setDefaultCloseOperation(DO_NOTHING_ON_CLOSE);

It will work.

Simply convert boolean field to integer and do a sum. This will work on postgresql :

select sum(myCol::int) from <table name>

Hope that helps!

The prompt command will echo text to the output:

prompt A useful comment.
select(*) from TableA;

Will be displayed as:

SQL> A useful comment.
SQL>

Getting Different Types of Extra from Intent

To access data from Intent you should know two things.

• KEY
• DataType of your data.

There are different methods in Intent class to extract different kind of data types. It looks like this

getIntent().XXXX(KEY) or intent.XXX(KEY);

So if you know the datatype of your varibale which you set in otherActivity you can use the respective method.

Example to retrieve String in your Activity from Intent

String profileName = getIntent().getStringExtra("SomeKey");

List of different variants of methods for different dataType

You can see the list of available methods in Official Documentation of Intent.

This is the VBA that I use to open the current path in an Explorer window:

Shell Environ("windir") & "\explorer.exe """ & CurDir() & "",vbNormalFocus

Microsoft Documentation:

• CurDir Function
• Environ Function
• Shell Function

In my case dll was not copied although I added a reference to it. This is because EntityFramework.SqlServer.dllis not copied into your project. Add that dll and it will hopefully work.You can find that from the project where you added datamodel.

Here is another solution which uses any/2

map(select(any(.Names[]; contains("data"))|not)|.Id)[]

with the sample data and the -r option it produces

If you don't mind creating an extra date object, you could try:

var tempDate = new Date(parseInt(item.timestamp, 10));
var visitDate = new Date (tempDate.getUTCFullYear(), tempDate.getUTCMonth(), tempDate.getUTCDate());

I do something very similar to get a date of the current month without the time.

Brief and simple

It is a function which returns another function written in short way.

const handleChange = field => e => {
  e.preventDefault()
  // Do something here
}

// is equal to 
function handleChange(field) {
  return function(e) {
    e.preventDefault()
    // Do something here
  }
}

Why people do it ?

Have you faced when you need to write a function which can be customized? Or you have to write a callback function which has fixed parameters (arguments), but you need to pass more variables to the function but avoiding global variables? If your answer "yes" then it is the way how to do it.

For example we have a button with onClick callback. And we need to pass id to the function, but onClick accepts only one parameter event, we can not pass extra parameters within like this:

const handleClick = (event, id) {
  event.preventDefault()
  // Dispatch some delete action by passing record id
}

It will not work!

Therefore we make a function which will return other function with its own scope of variables without any global variables, because global variables are evil .

Below the function handleClick(props.id)} will be called and return a function and it will have id in its scope! No matter how many times it will be pressed the ids will not effect or change each other, they are totally isolated.

const handleClick = id => event {
  event.preventDefault()
  // Dispatch some delete action by passing record id
}

const Confirm = props => (
  <div>
    <h1>Are you sure to delete?</h1>
    <button onClick={handleClick(props.id)}>
      Delete
    </button>
  </div
)

Other benefit

A function which returns another function also called "curried functions" and they are used for function compositions.

You can find example here: https://gist.github.com/sultan99/13ef56b4089789a8d115869ee2c5ec47

The typical use is

void* ret = NULL;
pthread_t tid = something; /// change it suitably
if (pthread_join (tid, &ret)) 
   handle_error();
// do something with the return value ret

Using

dependencies:
  connectivity: ^0.4.2

what we got from resouces is

      import 'package:connectivity/connectivity.dart';

      Future<bool> check() async {
        var connectivityResult = await (Connectivity().checkConnectivity());
        if (connectivityResult == ConnectivityResult.mobile) {
          return true;
        } else if (connectivityResult == ConnectivityResult.wifi) {
          return true;
        }
        return false;
      }

Future is little problematic for me, we have to implement it every single time like :

check().then((intenet) {
      if (intenet != null && intenet) {
        // Internet Present Case
      }
      // No-Internet Case
    });

So to solve this problem i have created a class Which accept a function with boolean isNetworkPresent parameter like this

methodName(bool isNetworkPresent){}

And the Utility Class is

import 'package:connectivity/connectivity.dart';

class NetworkCheck {
  Future<bool> check() async {
    var connectivityResult = await (Connectivity().checkConnectivity());
    if (connectivityResult == ConnectivityResult.mobile) {
      return true;
    } else if (connectivityResult == ConnectivityResult.wifi) {
      return true;
    }
    return false;
  }

  dynamic checkInternet(Function func) {
    check().then((intenet) {
      if (intenet != null && intenet) {
        func(true);
      }
      else{
    func(false);
  }
    });
  }
}

And to use connectivity-check utilty

  fetchPrefrence(bool isNetworkPresent) {
    if(isNetworkPresent){

    }else{

    }
  }

i will use this syntax

NetworkCheck networkCheck = new NetworkCheck();
networkCheck.checkInternet(fetchPrefrence)

Try one of these:

• ApplicationRef.tick() - similar to AngularJS's $rootScope.$digest() -- i.e., check the full component tree
• NgZone.run(callback) - similar to $rootScope.$apply(callback) -- i.e., evaluate the callback function inside the Angular zone. I think, but I'm not sure, that this ends up checking the full component tree after executing the callback function.
• ChangeDetectorRef.detectChanges() - similar to $scope.$digest() -- i.e., check only this component and its children

You can inject ApplicationRef, NgZone, or ChangeDetectorRef into your component.

For the actual processing I'd keep a string of finished product, and loop through each letter in the string they have entered. I'd call a function to convert a letter to morse code, then add it to the string of existing morse code.

finishedProduct = []
userInput = input("Enter text")
for letter in userInput:
    finishedProduct.append( letterToMorseCode(letter) )
theString = ''.join(finishedProduct)
print(theString)

You could either check for space in the loop, or in the function that is called.

Also you can use LINQ's Select Method:

var source = new[] { "Line 1", "Line 2" };

var result = source.Select(s => s + " roxxors");

Read more here Enumerable.Select Method

Do you really need to keep the session (do you have data in it?) or is it enough to fake this by reinstantiating the session when a request comes in? If the first, use the method above. If the second, try something like using the Session_End event handler.

If you have Forms Authentication, then you get something in the Global.asax.cs like

FormsAuthenticationTicket ticket = FormsAuthentication.Decrypt(formsCookie.Value);
if (ticket.Expired)
{
    Request.Cookies.Remove(FormsAuthentication.FormsCookieName);
    FormsAuthentication.SignOut();
    ...             
     }
else
{   ...
    // renew ticket if old
    ticket = FormsAuthentication.RenewTicketIfOld(ticket);
    ...
     }

And you set the ticket lifetime much longer than the session lifetime. If you're not authenticating, or using a different authentication method, there are similar tricks. Microsoft TFS web interface and SharePoint seem to use these - the give away is that if you click a link on a stale page, you get authentication prompts in the popup window, but if you just use a command, it works.

In java 8 , It's really easy to get timestamp in UTC by using java 8 java.time.Instant library :

Instant.now();

That few word of code will return the UTC Timestamp.

I had the same problem, resolved it by adding

<filtering>true</filtering> 

in pom.xml :

before (didn't work):

<build>
    <resources>
        <resource>
            <directory>src/main/resources</directory>               
        </resource>
    </resources>
</build>

after(it worked):

<build>
    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <filtering>true</filtering>
        </resource>
    </resources>
</build>

After that you just run mvn clean install and deploy application.

You have to give a valid username. For example, to run query with user root you have to type the following command and then enter password when prompted:

mysql -u root -p

Once you are connected, prompt will be something like:

mysql>

Here you can write your query, after database selection, for example:

mysql> USE your_database;
mysql> SELECT * FROM your_table;

Use references all the time and pointers only when you have to refer to NULL which reference cannot refer.

I have the latest Android Studio 3.6.1 and yet couldn't build a simple 'Hello World' app as documented here "https://codelabs.developers.google.com/codelabs/android-training-hello-world/index.html?index=..%2F..%2Fandroid-training#3". I applied various steps discussed above including the 2 most viable options which should have really solved this issue,

1. 'File->Sync Project with Gradle Files' and
2. 'File->Invalidate Caches/Restart' but to no avail.

Even though, I suspect standard answer should be one of these 2 options only for most, but for me the resolution came only after I went inside the 'File->Project Structure' and checked my SDK versions configured! Android Studio and Gradle were using different JDK versions and locations.

• Android Studio: C:\Program Files\Java\jdk1.8.0_241
• Gradle: C:\Program Files\Java\jdk-13.0.2

I had previously defined my JAVA_HOME environment variable by downloading latest JAVA SDK on my own from ORACLE website. Where Gradle was using the %JAVA_HOME% JAVA SDK version and Android Studio the built in SDK which came along with Android Studio.

Once I switched both to versions JDK 1.8.* (Any version as long as it is JDK 1.8. for that matter*) then simple 'File->Synch...' option worked perfectly fine for me!

Good luck the solution is in between one of these 2 options only if you are stuck, just ensure you validate JDK versions being referred to!

It's fairly simple. You write values using keys and expiry times. You get values using keys. You can expire keys from the system.

Most clients follow the same rules. You can read the generic instructions and best practices on the memcached homepage.

If you really want to dig into it, I'd look at the source. Here's the header comment:

"""
client module for memcached (memory cache daemon)

Overview
========

See U{the MemCached homepage<http://www.danga.com/memcached>} for more about memcached.

Usage summary
=============

This should give you a feel for how this module operates::

    import memcache
    mc = memcache.Client(['127.0.0.1:11211'], debug=0)

    mc.set("some_key", "Some value")
    value = mc.get("some_key")

    mc.set("another_key", 3)
    mc.delete("another_key")

    mc.set("key", "1")   # note that the key used for incr/decr must be a string.
    mc.incr("key")
    mc.decr("key")

The standard way to use memcache with a database is like this::

    key = derive_key(obj)
    obj = mc.get(key)
    if not obj:
        obj = backend_api.get(...)
        mc.set(key, obj)

    # we now have obj, and future passes through this code
    # will use the object from the cache.

Detailed Documentation
======================

More detailed documentation is available in the L{Client} class.

I used this for a similar problem:

'catherine mc-nulty joséphina'.capitalize.gsub(/(\s+\w)/) { |stuff| stuff.upcase }

This handles the following weird cases I saw trying the previous answers:

• non-word characters like -
• accented characters common in names like é
• capital characters in the middle of the string

Swift 4, I have used Enum for handling UserDefaults.

This is just a sample code. You can customize it as per your requirements.

For Storing, Retrieving, Removing. In this way just add a key for your UserDefaults key to the enum. Handle values while getting and storing according to dataType and your requirements.

enum UserDefaultsConstant : String {
    case AuthToken, FcmToken

    static let defaults = UserDefaults.standard


   //Store
    func setValue(value : Any) {
        switch self {
        case .AuthToken,.FcmToken:
            if let _ = value as? String {
                UserDefaults.standard.set(value, forKey: self.rawValue)
            }
            break
        }

        UserDefaults.standard.synchronize()
    }

   //Retrieve
    func getValue() -> Any? {
        switch self {
        case .AuthToken:
            if(UserDefaults.standard.value(forKey: UserDefaultsConstant.AuthToken.rawValue) != nil) {

                return "Bearer "+(UserDefaults.standard.value(forKey: UserDefaultsConstant.AuthToken.rawValue) as! String)
            }
            else {
                return ""
            }

        case .FcmToken:

            if(UserDefaults.standard.value(forKey: UserDefaultsConstant.FcmToken.rawValue) != nil) {
                print(UserDefaults.standard.value(forKey: UserDefaultsConstant.FcmToken.rawValue))
                return (UserDefaults.standard.value(forKey: UserDefaultsConstant.FcmToken.rawValue) as! String)
            }
            else {
                return ""
            }
        }
    }

    //Remove
    func removeValue() {
        UserDefaults.standard.removeObject(forKey: self.rawValue)
        UserDefaults.standard.synchronize()
    }
}

For storing a value in userdefaults,

if let authToken = resp.data?.token {
     UserDefaultsConstant.AuthToken.setValue(value: authToken)
    }

For retrieving a value from userdefaults,

//As AuthToken value is a string
    (UserDefaultsConstant.AuthToken.getValue() as! String)

This is the best way (IMHO).

List<String> myArrayList = new ArrayList<String>();
//.....
String[] myArray = myArrayList.toArray(new String[myArrayList.size()]);

This code works also:

String[] myArray = myArrayList.toArray(new String[0]);

But it less effective: the string array is created twice: first time zero-length array is created, then the real-size array is created, filled and returned. So, if since you know the needed size (from list.size()) you should create array that is big enough to put all elements. In this case it is not re-allocated.

The UPDATE syntax is:

[ WITH [ RECURSIVE ] with_query [, ...] ]
UPDATE [ ONLY ] table [ [ AS ] alias ]
    SET { column = { expression | DEFAULT } |
          ( column [, ...] ) = ( { expression | DEFAULT } [, ...] ) } [, ...]
    [ FROM from_list ]
    [ WHERE condition | WHERE CURRENT OF cursor_name ]
    [ RETURNING * | output_expression [ [ AS ] output_name ] [, ...] ]

In your case I think you want this:

UPDATE vehicles_vehicle AS v 
SET price = s.price_per_vehicle
FROM shipments_shipment AS s
WHERE v.shipment_id = s.id 

Soulution n +=1

def foo():
  foo.__dict__.setdefault('count', 0)
  foo.count += 1
  return foo.count

Use git show $COMMIT. It'll show you the log message for the commit, and the diff of that particular commit.

You can either:

• Use XmlSerializer class
• Use XmlDocument class

All these answers are partially wrong.

Microsoft has clarified that Community is for ANY USE as long as your revenue is under $1 Million US dollars. That is literally the only difference between Pro and Community. Corporate or free or not, irrelevant.

Even the lack of TFS support is not true. I can verify it is present and works perfectly.

EDIT: Here is an MSDN post regarding the $1M limit: MSDN (hint: it's in the VS 2017 license)

EDIT: Even over the revenue limit, open source is still free.

Yes you can, for example:

[textField setKeyboardType:UIKeyboardTypeNumberPad];

Self plug: I have just released a new Java HTML parser: jsoup. I mention it here because I think it will do what you are after.

Its party trick is a CSS selector syntax to find elements, e.g.:

String html = "<html><head><title>First parse</title></head>"
  + "<body><p>Parsed HTML into a doc.</p></body></html>";
Document doc = Jsoup.parse(html);
Elements links = doc.select("a");
Element head = doc.select("head").first();

See the Selector javadoc for more info.

This is a new project, so any ideas for improvement are very welcome!

it worked for me using this line of code:

<a id="LinkTest" title="Any Title"  href="#" onclick="Function(); return false; ">text</a>

Here is a little work around that I created. I checked it with R and it works correct.

import numpy as np
import statsmodels.api as sm

y = [1,2,3,4,3,4,5,4,5,5,4,5,4,5,4,5,6,5,4,5,4,3,4]

x = [
     [4,2,3,4,5,4,5,6,7,4,8,9,8,8,6,6,5,5,5,5,5,5,5],
     [4,1,2,3,4,5,6,7,5,8,7,8,7,8,7,8,7,7,7,7,7,6,5],
     [4,1,2,5,6,7,8,9,7,8,7,8,7,7,7,7,7,7,6,6,4,4,4]
     ]

def reg_m(y, x):
    ones = np.ones(len(x[0]))
    X = sm.add_constant(np.column_stack((x[0], ones)))
    for ele in x[1:]:
        X = sm.add_constant(np.column_stack((ele, X)))
    results = sm.OLS(y, X).fit()
    return results

Result:

print reg_m(y, x).summary()

Output:

Yes, you can install an interrupt handler using the module signal, and wait forever using a threading.Event:

import signal
import sys
import time
import threading

def signal_handler(signal, frame):
    print('You pressed Ctrl+C!')
    sys.exit(0)

signal.signal(signal.SIGINT, signal_handler)
print('Press Ctrl+C')
forever = threading.Event()
forever.wait()

Lazy loading will produce several SQL calls while Eager loading may load data with one "more heavy" call (with joins/subqueries).

For example, If there is a high ping between your web and sql servers you would go with Eager loading instead of loading related items 1-by-1 with lazy Loading.

Welp it looks like my decision to install "graphics magick" over "image magick" has some rough edges - when I reinstall genuine crufty old "image magick", then the above command works perfectly well.

edit, a long time later — One of these days I'll check to see if "graphics magick" has fixed this issue.

I experienced the same error message. I managed to fix it:

In my case the error was that I missed the [datacontract] and [datamember] attributes in the parent class of my returned class. The error message was misleading.

[DataContract]
public class MyClass : MyParentClass
{       
    [DataMember]
    public string SomeString { get; set; }      
}

// Missing DataContract

    // Missing DataMember

Others have answered your earlier question. For this:

As an addendum, is there any way to extract directly with the header names rather than with column numbers?

I haven't tried it, but you could store each header's index in a hash and then use that hash to get its index later on.

for(i=0;i<$NF;i++){
    hash[$i] = i;
}

Then later on, use it:

j = hash["header1"];
print $j;

You need to use the ajax-cross-origin plugin: http://www.ajax-cross-origin.com/

Just add the option crossOrigin: true

$.ajax({
    crossOrigin: true,
    url: url,
    success: function(data) {
        console.log(data);
    }
});

I faced this error when I created second activity in my project in the newly updated Android Studio,I solved it simply by copy pasting the whole xml code from first layout to the second and then I just removed the code that's unnecessary.

Whevever you get a problem like this just go to the man page for the function in question and it will tell you what header you are missing, e.g.

$ man memset

MEMSET(3)                BSD Library Functions Manual                MEMSET(3)

NAME
     memset -- fill a byte string with a byte value

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <string.h>

     void *
     memset(void *b, int c, size_t len);

Note that for C++ it's generally preferable to use the proper equivalent C++ headers, <cstring>/<cstdio>/<cstdlib>/etc, rather than C's <string.h>/<stdio.h>/<stdlib.h>/etc.

Although many correct answers have already been given, the classical (read non-DOM) approach would be like this:

document.forms['yourform']['yourtextarea'].value = 'yourvalue';

where in the HTML your textarea is nested somewhere in a form like this:

<form name="yourform">
    <textarea name="yourtextarea" rows="10" cols="60"></textarea>
</form>

And as it happens, that would work with Netscape Navigator 4 and Internet Explorer 3 too. And, not unimportant, Internet Explorer on mobile devices.

First, please do not use extract(), it can be a security problem because it is easy to manipulate POST parameters

In addition, you don't have to use variable variable names (that sounds odd), instead:

foreach($_POST as $key => $value) {
  echo "POST parameter '$key' has '$value'";
}

To ensure that you have only parameters beginning with 'item_name' you can check it like so:

$param_name = 'item_name';
if(substr($key, 0, strlen($param_name)) == $param_name) {
  // do something
}

A call to EntityManager.flush(); will force the data to be persist in the database immediately as EntityManager.persist() will not (depending on how the EntityManager is configured : FlushModeType (AUTO or COMMIT) by default it's set to AUTO and a flush will be done automatically by if it's set to COMMIT the persitence of the data to the underlying database will be delayed when the transaction is commited).

There's a great article on Mozilla's MDN docs that describes exactly this issue:

The "Unicode Problem" Since DOMStrings are 16-bit-encoded strings, in most browsers calling window.btoa on a Unicode string will cause a Character Out Of Range exception if a character exceeds the range of a 8-bit byte (0x00~0xFF). There are two possible methods to solve this problem:

• the first one is to escape the whole string (with UTF-8, see encodeURIComponent) and then encode it;
• the second one is to convert the UTF-16 DOMString to an UTF-8 array of characters and then encode it.

A note on previous solutions: the MDN article originally suggested using unescape and escape to solve the Character Out Of Range exception problem, but they have since been deprecated. Some other answers here have suggested working around this with decodeURIComponent and encodeURIComponent, this has proven to be unreliable and unpredictable. The most recent update to this answer uses modern JavaScript functions to improve speed and modernize code.

If you're trying to save yourself some time, you could also consider using a library:

• js-base64 (NPM, great for Node.js)
• base64-js

Encoding UTF8 ? base64

function b64EncodeUnicode(str) {
    // first we use encodeURIComponent to get percent-encoded UTF-8,
    // then we convert the percent encodings into raw bytes which
    // can be fed into btoa.
    return btoa(encodeURIComponent(str).replace(/%([0-9A-F]{2})/g,
        function toSolidBytes(match, p1) {
            return String.fromCharCode('0x' + p1);
    }));
}

b64EncodeUnicode('? à la mode'); // "4pyTIMOgIGxhIG1vZGU="
b64EncodeUnicode('\n'); // "Cg=="

Decoding base64 ? UTF8

function b64DecodeUnicode(str) {
    // Going backwards: from bytestream, to percent-encoding, to original string.
    return decodeURIComponent(atob(str).split('').map(function(c) {
        return '%' + ('00' + c.charCodeAt(0).toString(16)).slice(-2);
    }).join(''));
}

b64DecodeUnicode('4pyTIMOgIGxhIG1vZGU='); // "? à la mode"
b64DecodeUnicode('Cg=='); // "\n"

The pre-2018 solution (functional, and though likely better support for older browsers, not up to date)

Here is the the current recommendation, direct from MDN, with some additional TypeScript compatibility via @MA-Maddin:

// Encoding UTF8 ? base64

function b64EncodeUnicode(str) {
    return btoa(encodeURIComponent(str).replace(/%([0-9A-F]{2})/g, function(match, p1) {
        return String.fromCharCode(parseInt(p1, 16))
    }))
}

b64EncodeUnicode('? à la mode') // "4pyTIMOgIGxhIG1vZGU="
b64EncodeUnicode('\n') // "Cg=="

// Decoding base64 ? UTF8

function b64DecodeUnicode(str) {
    return decodeURIComponent(Array.prototype.map.call(atob(str), function(c) {
        return '%' + ('00' + c.charCodeAt(0).toString(16)).slice(-2)
    }).join(''))
}

b64DecodeUnicode('4pyTIMOgIGxhIG1vZGU=') // "? à la mode"
b64DecodeUnicode('Cg==') // "\n"

The original solution (deprecated)

This used escape and unescape (which are now deprecated, though this still works in all modern browsers):

function utf8_to_b64( str ) {
    return window.btoa(unescape(encodeURIComponent( str )));
}

function b64_to_utf8( str ) {
    return decodeURIComponent(escape(window.atob( str )));
}

// Usage:
utf8_to_b64('? à la mode'); // "4pyTIMOgIGxhIG1vZGU="
b64_to_utf8('4pyTIMOgIGxhIG1vZGU='); // "? à la mode"

And one last thing: I first encountered this problem when calling the GitHub API. To get this to work on (Mobile) Safari properly, I actually had to strip all white space from the base64 source before I could even decode the source. Whether or not this is still relevant in 2017, I don't know:

function b64_to_utf8( str ) {
    str = str.replace(/\s/g, '');    
    return decodeURIComponent(escape(window.atob( str )));
}

This was a problem for me for a long time. I had to come up with a solution that can be easily migrated once we get Elvis operator or something.

This is what I use; works for both arrays and objects

put this in tools.js file or something

// this will create the object/array if null
Object.prototype.__ = function (prop) {
    if (this[prop] === undefined)
        this[prop] = typeof prop == 'number' ? [] : {}
    return this[prop]
};

// this will just check if object/array is null
Object.prototype._ = function (prop) {
    return this[prop] === undefined ? {} : this[prop]
};

usage example:

let student = {
    classes: [
        'math',
        'whatev'
    ],
    scores: {
        math: 9,
        whatev: 20
    },
    loans: [
        200,
        { 'hey': 'sup' },
        500,
        300,
        8000,
        3000000
    ]
}

// use one underscore to test

console.log(student._('classes')._(0)) // math
console.log(student._('classes')._(3)) // {}
console.log(student._('sports')._(3)._('injuries')) // {}
console.log(student._('scores')._('whatev')) // 20
console.log(student._('blabla')._('whatev')) // {}
console.log(student._('loans')._(2)) // 500 
console.log(student._('loans')._(1)._('hey')) // sup
console.log(student._('loans')._(6)._('hey')) // {} 

// use two underscores to create if null

student.__('loans').__(6)['test'] = 'whatev'

console.log(student.__('loans').__(6).__('test')) // whatev

well I know it makes the code a bit unreadable but it's a simple one liner solution and works great. I hope it helps someone :)

Untested. Modify to suit:

$form = $('#my-form');

$rows = $form.find('.person-input-row');

$('button#add-new').click(function() {

    $rows.find(':first').clone().insertAfter($rows.find(':last'));

    $justInserted = $rows.find(':last');
    $justInserted.hide();
    $justInserted.find('input').val(''); // it may copy values from first one
    $justInserted.slideDown(500);


});

This is better than copying innerHTML because you will lose all attached events etc.

Using a null reference as the first operand to instanceof returns false.

        Public Function VLOOKUP1(ByVal lookup_value As String, ByVal table_array As Range, ByVal col_index_num As Integer) As String
        Dim i As Long

        For i = 1 To table_array.Rows.Count
            If lookup_value = table_array.Cells(table_array.Row + i - 1, 1) Then
                VLOOKUP1 = table_array.Cells(table_array.Row + i - 1, col_index_num)
                Exit For
            End If
        Next i

        End Function

Move import sys outside of the try-except block:

import sys
try:
    # ...
except ImportError:
    # ...

If any of the imports before the import sys line fails, the rest of the block is not executed, and sys is never imported. Instead, execution jumps to the exception handling block, where you then try to access a non-existing name.

sys is a built-in module anyway, it is always present as it holds the data structures to track imports; if importing sys fails, you have bigger problems on your hand (as that would indicate that all module importing is broken).

Compare date time objects:

(I picked 10 days - Anything older than 10 days is "OLD", else "NEW")

$now   = new DateTime();
$diff=date_diff($yourdate,$now);
$diff_days = $diff->format("%a");
if($diff_days > 10){
    echo "OLD! " . $yourdate->format('m/d/Y');
}else{
    echo "NEW! " . $yourdate->format('m/d/Y');
}

Alternatively to hobodave's answer

SELECT * FROM table
WHERE YEAR(date_created) = YEAR(CURRENT_DATE - INTERVAL 1 MONTH)
AND MONTH(date_created) = MONTH(CURRENT_DATE - INTERVAL 1 MONTH)

You could achieve the same with EXTRACT, using YEAR_MONTH as unit, thus you wouldn't need the AND, like so:

SELECT * FROM table
WHERE EXTRACT(YEAR_MONTH FROM date_created) = EXTRACT(YEAR_MONTH FROM CURDATE() - INTERVAL
1 MONTH)

Though an old question, I would like to add that currently mock library (backport of unittest.mock) supports assert_not_called method.

Just upgrade yours;

pip install mock --upgrade

Percent encoding. Replace the hash with %23.

I know this isn't a direct answer to your question, but you could also consider using clip-path, as in this question: https://stackoverflow.com/a/18208889/23341.

As defined in the MySQL Glossary:

In MySQL, physically, a schema is synonymous with a database. You can substitute the keyword SCHEMA instead of DATABASE in MySQL SQL syntax, for example using CREATE SCHEMA instead of CREATE DATABASE.

Some other database products draw a distinction. For example, in the Oracle Database product, a schema represents only a part of a database: the tables and other objects owned by a single user.

This answer is not ideal any more since CSS flexbox and grid where implemented to CSS. However it is still a working solution

On a smaller screen you would probably want to keep the height auto as the col1, col2 and col3 are stacked on one another.

However after a media query breakpoint you would like cols to appear next to each other with an equal height for all columns.

1125 px is only an example of window width breakpoint after which you would want to make all columns set to the same height.

<div class="wraper">
    <div class="col1">Lorem ipsum dolor sit amet.</div>
    <div class="col2">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Eos laudantium, possimus sed, debitis amet in, explicabo dolor similique eligendi officia numquam eaque quae illo magnam distinctio odio, esse vero aspernatur.</div>
    <div class="col3">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Dolorem, odio qui praesentium.</div>
</div>

You could, of course, set more breakpoints if you need to.

<script>
    $(document).ready(function(){
        $(window).on('load resize', function() {
            let vraperH = $('.wraper').height();
            if (window.innerWidth>= 1125) {
              $('.col1').height(vraperH);
              $('.col2').height(vraperH);
              $('.col3').height(vraperH);
            }
            if (window.innerWidth < 1125) {
              $('.col1').height('auto');
              $('.col2').height('auto');
              $('.col3').height('auto');
            }
        });
    });
</script>

How did you upload those images; via FTP or through WP uploader? You have to upload images THROUGH WP uploader in order to show them in the image library.

You should change your parenthesis to

while((c = getchar()) != EOF)

Because the "=" operator has a lower precedence than the "!=" operator. Then you will get the expected results. Your expression is equal to

while (c = (getchar()!= EOF))

You are getting the two 1's as output, because you are making the comparison "c!=EOF". This will always become one for the character you entered and then the "\n" that follows by hitting return. Except for the last comparison where c really is EOF it will give you a 0.

EDIT about EOF: EOF is typically -1, but this is not guaranteed by the standard. The standard only defines about EOF in section 7.19.1:

EOF which expands to an integer constant expression, with type int and a negative value, that is returned by several functions to indicate end-of-file, that is, no more input from a stream;

It is reasonable to assume that EOF equals -1, but when using EOF you should not test against the specific value, but rather use the macro.

Can't you use the first selector ?

something like: tr:first

A very simple but unsafe implementation to read line for static allocation:

char line[1024];

scanf("%[^\n]", line);

A safer implementation, without the possibility of buffer overflow, but with the possibility of not reading the whole line, is:

char line[1024];

scanf("%1023[^\n]", line);

Not the 'difference by one' between the length specified declaring the variable and the length specified in the format string. It is a historical artefact.

Use PHP_EOL which produces \r\n or \n

$data = 'my data' . PHP_EOL . 'my data';
$fp = fopen('my_file', 'a');
fwrite($fp, $data);
fclose($fp);

// File output

my data
my data

git log -n 1 [branch_name]

branch_name (may be remote or local branch) is optional. Without branch_name, it will show the latest commit on the current branch.

For example:

git log -n 1
git log -n 1 origin/master
git log -n 1 some_local_branch

git log -n 1 --pretty=format:"%H"  #To get only hash value of commit

You need to set utf8mb4 in meta html and also in your server alter tabel and set collation to utf8mb4

The error code 10060 means it cannot connect to the remote peer. It might be because of the network problem or mostly your setting issues, such as proxy setting.

You could try to connect the same host with other tools(such as ncat) and/or with another PC within your same local network to find out where the problem is occuring.

For proxy issue, there are some material here:

Using an HTTP PROXY - Python

Why can't I get Python's urlopen() method to work on Windows?

Hope it helps!

If you have heading to your table columns and you don't want to scroll those headings then this solution could help you:

This solution needs thead and tbody tags inside table element.

table.tableSection {
    display: table;
    width: 100%;
}
table.tableSection thead, table.tableSection tbody {
    float: left;
    width: 100%;
}
table.tableSection tbody {
    overflow: auto;
    height: 150px;
}
table.tableSection tr {
    width: 100%;
    display: table;
    text-align: left;
}
table.tableSection th, table.tableSection td {
    width: 33%;
}

Working fiddle

With comments

Note: If you are sure that the vertical scrollbar is always present, then you can use css3 calc property to make the thead cells align with the tbody cells.

table.tableSection thead {
    padding-right:18px;   /* 18px is approx. value of width of scroll bar */
    width: calc(100% - 18px);
}

You can do the same by detecting presence of scrollbar using javascript and applying the above styles.

Since you're writing a calculator that would presumably also accept floats (1.5, 0.03), a more robust way would be to use this simple helper function:

def convertStr(s):
    """Convert string to either int or float."""
    try:
        ret = int(s)
    except ValueError:
        #Try float.
        ret = float(s)
    return ret

That way if the int conversion doesn't work, you'll get a float returned.

Edit: Your division function might also result in some sad faces if you aren't fully aware of how python 2.x handles integer division.

In short, if you want 10/2 to equal 2.5 and not 2, you'll need to do from __future__ import division or cast one or both of the arguments to float, like so:

def division(a, b):
    return float(a) / float(b)

java packages are base, and javax packages are extensions.

Swing was an extension because AWT was the original UI API. Swing came afterwards, in version 1.1.

` Please include either of these:

C++ language has no such thing as typeof. You must be looking at some compiler-specific extension. If you are talking about GCC's typeof, then a similar feature is present in C++11 through the keyword decltype. Again, C++ has no such typeof keyword.

typeid is a C++ language operator which returns type identification information at run time. It basically returns a type_info object, which is equality-comparable with other type_info objects.

Note, that the only defined property of the returned type_info object has is its being equality- and non-equality-comparable, i.e. type_info objects describing different types shall compare non-equal, while type_info objects describing the same type have to compare equal. Everything else is implementation-defined. Methods that return various "names" are not guaranteed to return anything human-readable, and even not guaranteed to return anything at all.

Note also, that the above probably implies (although the standard doesn't seem to mention it explicitly) that consecutive applications of typeid to the same type might return different type_info objects (which, of course, still have to compare equal).

First off you can't have just a number for your id unless you are using the HTML5 DOCTYPE. Secondly, you need to either remove the # in each id or replace it with this:

$container.cycle(id.replace('#',''));
