The instanceof operator does not need explicit null checks, as it does not throw a NullPointerException if the operand is null.

At run time, the result of the instanceof operator is true if the value of the relational expression is not null and the reference could be cast to the reference type without raising a class cast exception.

If the operand is null, the instanceof operator returns false and hence, explicit null checks are not required.

Consider the below example,

public static void main(String[] args) {
         if(lista != null && lista instanceof ArrayList) {                     //Violation
                System.out.println("In if block");
         }
         else {
                System.out.println("In else block");
         }
}

The correct usage of instanceof is as shown below,

public static void main(String[] args) {
      
         if(lista instanceof ArrayList){                     //Correct way
                  System.out.println("In if block");
         }
            else {
                 System.out.println("In else block");
         }  
}

Try writing all the errors to a file.

error_reporting(-1); // reports all errors
ini_set("display_errors", "1"); // shows all errors
ini_set("log_errors", 1);
ini_set("error_log", "/tmp/php-error.log");

Something like that.

There are several ways to do this:

A simple way is using the os module:

import os
os.system("ls -l")

More complex things can be achieved with the subprocess module: for example:

import subprocess
test = subprocess.Popen(["ping","-W","2","-c", "1", "192.168.1.70"], stdout=subprocess.PIPE)
output = test.communicate()[0]

In this context components to me sound like isolated runtime portions of an engine that may execute concurrently with other components. If this is the motivation then you might want to look at the actor model and systems that make use of it.

Another way similar to the yglodt's

In application.properties:

spring.jpa.properties.hibernate.current_session_context_class=org.springframework.orm.hibernate4.SpringSessionContext

And in your configuration class:

@Bean
public SessionFactory sessionFactory(HibernateEntityManagerFactory hemf) {
    return hemf.getSessionFactory();
}

Then you can autowire the SessionFactory in your services as usual:

@Autowired
private SessionFactory sessionFactory;

When I have to do a fast verification, I write this simple code based on the basic division between numbers lower than square root of input.

def isprime(n):
    if n%2==0:
        return n==2
    else:
        cota = int(n**0.5)+1
        for ind in range(3,2,cota):
            if n%ind==0:
                print(ind)
                return False
    is_one = n==1
    return True != is_one

isprime(22783)

• The last True != n==1 is to avoid the case n=1.

I like to set the 'line-height' in the css for the divs to get them to line up properly. Here is an example of how I do it using asp and css:

ASP:

<div id="profileRow1">
    <div id="profileRow1Col1" class="righty">
        <asp:Label ID="lblCreatedDateLabel" runat="server" Text="Date Created:"></asp:Label><br />
        <asp:Label ID="lblLastLoginDateLabel" runat="server" Text="Last Login Date:"></asp:Label><br />
        <asp:Label ID="lblUserIdLabel" runat="server" Text="User ID:"></asp:Label><br />
        <asp:Label ID="lblUserNameLabel" runat="server" Text="Username:"></asp:Label><br />
        <asp:Label ID="lblFirstNameLabel" runat="server" Text="First Name:"></asp:Label><br />
        <asp:Label ID="lblLastNameLabel" runat="server" Text="Last Name:"></asp:Label><br />
    </div>
    <div id="profileRow1Col2">
        <asp:Label ID="lblCreatedDate" runat="server" Text="00/00/00 00:00:00"></asp:Label><br />
        <asp:Label ID="lblLastLoginDate" runat="server" Text="00/00/00 00:00:00"></asp:Label><br />
        <asp:Label ID="lblUserId" runat="server" Text="UserId"></asp:Label><br />
        <asp:TextBox ID="txtUserName" runat="server"></asp:TextBox><br />
        <asp:TextBox ID="txtFirstName" runat="server"></asp:TextBox><br />
        <asp:TextBox ID="txtLastName" runat="server"></asp:TextBox><br />
    </div>
</div>

And here is the code in the CSS file to make all of the above fields look nice and neat:

#profileRow1{width:100%;line-height:40px;}
#profileRow1Col1{float:left; width:25%; margin-right:20px;}
#profileRow1Col2{float:left; width:25%;}
.righty{text-align:right;}

you can basically pull everything but the DIV tags and replace with your own content.

Trust me when I say it looks aligned the way the image in the original post does!

The specific problem is that you're declaring a new variable instead of assigning to an existing one:

char * ret = new char[strlen(array) + 1 + 1];
^^^^^^ Remove this

and trying to compare string values by comparing pointers:

if (array!="")     // Wrong - compares pointer with address of string literal
if (array[0] == 0) // Better - checks for empty string

although there's no need to make that comparison at all; the first branch will do the right thing whether or not the string is empty.

The more general problem is that you're messing around with nasty, error-prone C-style string manipulation in C++. Use std::string and it will manage all the memory allocation for you:

std::string appendCharToString(std::string const & s, char a) {
    return s + a;
}

It's

#include <stdio.h>

int main(void) {
  int x = 10;
  while (x-- > 0) { // x goes to 0
    printf("%d ", x);
  }
  return 0;
}

Just the space makes the things look funny, -- decrements and > compares.

I just love getting information like BalusC gives here - and he is kind enough to help SO many people with such GOOD information that I regard his words as gospel, but I was not able to use that order of events to solve this same kind of timing issue in my project. Since BalusC put a great general reference here that I even bookmarked, I thought I would donate my solution for some advanced timing issues in the same place since it does solve the original poster's timing issues as well. I hope this code helps someone:

        <p:pickList id="formPickList" 
                    value="#{mediaDetail.availableMedia}" 
                    converter="MediaPicklistConverter" 
                    widgetVar="formsPicklistWidget" 
                    var="mediaFiles" 
                    itemLabel="#{mediaFiles.mediaTitle}" 
                    itemValue="#{mediaFiles}" >
            <f:facet name="sourceCaption">Available Media</f:facet>
            <f:facet name="targetCaption">Chosen Media</f:facet>
        </p:pickList>

        <p:commandButton id="viewStream_btn" 
                         value="Stream chosen media" 
                         icon="fa fa-download"
                         ajax="true"
                         action="#{mediaDetail.prepareStreams}"                                              
                         update=":streamDialogPanel"
                         oncomplete="PF('streamingDialog').show()"
                         styleClass="ui-priority-primary"
                         style="margin-top:5px" >
            <p:ajax process="formPickList"  />
        </p:commandButton>

The dialog is at the top of the XHTML outside this form and it has a form of its own embedded in the dialog along with a datatable which holds additional commands for streaming the media that all needed to be primed and ready to go when the dialog is presented. You can use this same technique to do things like download customized documents that need to be prepared before they are streamed to the user's computer via fileDownload buttons in the dialog box as well.

As I said, this is a more complicated example, but it hits all the high points of your problem and mine. When the command button is clicked, the result is to first insure the backing bean is updated with the results of the pickList, then tell the backing bean to prepare streams for the user based on their selections in the pick list, then update the controls in the dynamic dialog with an update, then show the dialog box ready for the user to start streaming their content.

The trick to it was to use BalusC's order of events for the main commandButton and then to add the <p:ajax process="formPickList" /> bit to ensure it was executed first - because nothing happens correctly unless the pickList updated the backing bean first (something that was not happening for me before I added it). So, yea, that commandButton rocks because you can affect previous, pending and current components as well as the backing beans - but the timing to interrelate all of them is not easy to get a handle on sometimes.

Happy coding!

System.out.println("wassup"); refers to when you have to output a certain result pertaining to the proper input given by the user whereas System.err.println("duh, that's wrong); is a reference to show that the input provided is wrong or there is some other error.

Most of the IDEs show this in red color (System.err.print).

Try this one using Grid Layout:

.grid-container {_x000D_
  display: grid;_x000D_
  grid-template-columns: auto auto auto;_x000D_
  padding: 10px;_x000D_
}_x000D_
.grid-item {_x000D_
  background-color: rgba(255, 255, 255, 0.8);_x000D_
  border: 1px solid rgba(0, 0, 0, 0.8);_x000D_
  padding: 20px;_x000D_
  font-size: 30px;_x000D_
  text-align: center;_x000D_
}

<div class="grid-container">_x000D_
  <div class="grid-item">1</div>_x000D_
  <div class="grid-item">2</div>_x000D_
  <div class="grid-item">3</div>  _x000D_
  <div class="grid-item">4</div>_x000D_
  <div class="grid-item">5</div>_x000D_
  <div class="grid-item">6</div>  _x000D_
  <div class="grid-item">7</div>_x000D_
  <div class="grid-item">8</div>_x000D_
  <div class="grid-item">9</div>  _x000D_
</div>

Run the compiler through OCR. It might solve the compatibility issue.

int sizeInDP = 16;

int marginInDp = (int) TypedValue.applyDimension(
            TypedValue.COMPLEX_UNIT_DIP, sizeInDP, getResources()
                    .getDisplayMetrics());

Then

layoutParams = myView.getLayoutParams()
layoutParams.setMargins(marginInDp, marginInDp, marginInDp, marginInDp);
myView.setLayoutParams(layoutParams);

Or

LayoutParams layoutParams = new LayoutParams...
layoutParams.setMargins(marginInDp, marginInDp, marginInDp, marginInDp);
myView.setLayoutParams(layoutParams);

Using the mysqli PHP driver, you can't get the insert_id after you commit.

The real solution is this:

function add_post($post_data){
  $this->db->trans_begin();
  $this->db->insert('posts',$post_data);

  $item_id = $this->db->insert_id();

  if( $this->db->trans_status() === FALSE )
  {
    $this->db->trans_rollback();
    return( 0 );
  }
  else
  {
    $this->db->trans_commit();
    return( $item_id );
  }
}

Use .help to check for available commands.

.table

This command would show all tables under your current database.

PHP has the new nice filter_input functions now, that for instance liberate you from finding 'the ultimate e-mail regex' now that there is a built-in FILTER_VALIDATE_EMAIL type

My own filter class (uses JavaScript to highlight faulty fields) can be initiated by either an ajax request or normal form post. (see the example below)

/**
 *  Pork.FormValidator
 *  Validates arrays or properties by setting up simple arrays. 
 *  Note that some of the regexes are for dutch input!
 *  Example:
 * 
 *  $validations = array('name' => 'anything','email' => 'email','alias' => 'anything','pwd'=>'anything','gsm' => 'phone','birthdate' => 'date');
 *  $required = array('name', 'email', 'alias', 'pwd');
 *  $sanitize = array('alias');
 *
 *  $validator = new FormValidator($validations, $required, $sanitize);
 *                  
 *  if($validator->validate($_POST))
 *  {
 *      $_POST = $validator->sanitize($_POST);
 *      // now do your saving, $_POST has been sanitized.
 *      die($validator->getScript()."<script type='text/javascript'>alert('saved changes');</script>");
 *  }
 *  else
 *  {
 *      die($validator->getScript());
 *  }   
 *  
 * To validate just one element:
 * $validated = new FormValidator()->validate('blah@bla.', 'email');
 * 
 * To sanitize just one element:
 * $sanitized = new FormValidator()->sanitize('<b>blah</b>', 'string');

Of course, keep in mind that you need to do your sql query escaping too depending on what type of db your are using (mysql_real_escape_string() is useless for an sql server for instance). You probably want to handle this automatically at your appropriate application layer like an ORM. Also, as mentioned above: for outputting to html use the other php dedicated functions like htmlspecialchars ;)

For really allowing HTML input with like stripped classes and/or tags depend on one of the dedicated xss validation packages. DO NOT WRITE YOUR OWN REGEXES TO PARSE HTML!

var sqlCommand = new SqlCommand("SELECT * FROM mytable WHERE start_time >= @StartTime");
sqlCommand.Parameters.Add("@StartTime", SqlDbType.DateTime);
sqlCommand.Parameters("@StartTime").Value = MyDateObj;

When converting datetime to integers one must keep in mind the tens, hundreds and thousands.... like "2018-11-03" must be like 20181103 in int for that you have to 2018*10000 + 100* 11 + 3

Similarly another example, "2018-11-03 10:02:05" must be like 20181103100205 in int

Explanatory Code

dt = datetime(2018,11,3,10,2,5)
print (dt)

#print (dt.timestamp()) # unix representation ... not useful when converting to int

print (dt.strftime("%Y-%m-%d"))
print (dt.year*10000 + dt.month* 100  + dt.day)
print (int(dt.strftime("%Y%m%d")))

print (dt.strftime("%Y-%m-%d %H:%M:%S"))
print (dt.year*10000000000 + dt.month* 100000000 +dt.day * 1000000 + dt.hour*10000  +  dt.minute*100 + dt.second)
print (int(dt.strftime("%Y%m%d%H%M%S")))

General Function

To avoid that doing manually use below function

def datetime_to_int(dt):
    return int(dt.strftime("%Y%m%d%H%M%S"))

I think you're looking for: SELECT a, b, COUNT(a) FROM tbl GROUP BY a, b

Make the list a character vector (not a vector of names)

rm(list = c('temp1','temp2'))

or

rm(temp1, temp2)

I was getting this error due to the BasicHttpBinding not sending a compatible messageVersion to the service i was calling. My solution was to use a custom binding like below

 <bindings>
  <customBinding>
    <binding name="Soap11UserNameOverTransport" openTimeout="00:01:00" receiveTimeout="00:1:00" >
      <security authenticationMode="UserNameOverTransport">
      </security>          
      <textMessageEncoding messageVersion="Soap11WSAddressing10" writeEncoding="utf-8" />
      <httpsTransport></httpsTransport>
    </binding>
  </customBinding>      
</bindings>

You can do this with a list comprehension:

T2 = [[int(column) for column in row] for row in T1]

The inner list comprehension ([int(column) for column in row]) builds a list of ints from a sequence of int-able objects, like decimal strings, in row. The outer list comprehension ([... for row in T1])) builds a list of the results of the inner list comprehension applied to each item in T1.

The code snippet will fail if any of the rows contain objects that can't be converted by int. You'll need a smarter function if you want to process rows containing non-decimal strings.

If you know the structure of the rows, you can replace the inner list comprehension with a call to a function of the row. Eg.

T2 = [parse_a_row_of_T1(row) for row in T1]

I had a slightly different problem. I worked with inputs in a modal and it drove me mad. No of the proposed solutions worked for me.

Until i found this issue: https://github.com/valor-software/ngx-bootstrap/issues/1597

This good guy gave me the hint that ngx-bootstrap modal has a focus configuration. If this configuration is not set to false, the modal will be focused after the animation and there is NO WAY to focus anything else.

Update:

To set this configuration, add the following attribute to the modal div:

[config]="{focus: false}"

Update 2:

To force the focus on the input field i wrote a directive and set the focus in every AfterViewChecked cycle as long as the input field has the class ng-untouched.

 ngAfterViewChecked() {
    // This dirty hack is needed to force focus on an input element of a modal.
    if (this.el.nativeElement.classList.contains('ng-untouched')) {
        this.renderer.invokeElementMethod(this.el.nativeElement, 'focus', []);
    }
}

Sticky notes in Windows 10 are stored here: C:\Users\"Username"\Appdata\Roaming\Microsoft\Sticky Notes

If you want to restore your sticky notes from earlier versions of windwos, just copy the .snt file and place it in the above location.

N.B: Replace only if you don't have any new notes in Windows 10!

The really simplified answer is that the kernel runs in kernel space, and normal programs run in user space. User space is basically a form of sand-boxing -- it restricts user programs so they can't mess with memory (and other resources) owned by other programs or by the OS kernel. This limits (but usually doesn't entirely eliminate) their ability to do bad things like crashing the machine.

The kernel is the core of the operating system. It normally has full access to all memory and machine hardware (and everything else on the machine). To keep the machine as stable as possible, you normally want only the most trusted, well-tested code to run in kernel mode/kernel space.

The stack is just another part of memory, so naturally it's segregated right along with the rest of memory.

When you set a string variable, it doesn't save quotes of it, they are a part of its definition. so you don't need to use :1

$('iframe').load(function(){
      $(".loading").remove();
    alert("iframe is done loading")
}).show();


<iframe src="http://www.google.com" style="display:none;" width="600" height="300"/>
<div class="loading" style="width:600px;height:300px;">iframe loading</div>

I have site developed using jquery ui, I just tried to plug in bootstrap for future development and styling but it breaks virtually everything.

So No they are not compatible.

Simply

Use elevation instead of zIndex for android devices

elevatedElement: {
  zIndex: 3, // works on ios
  elevation: 3, // works on android
}

This worked fine for me!

The ** syntax tells Python to collect keyword arguments into a dictionary. The save2 is passing it down as a non-keyword argument (a dictionary object). The openX is not seeing any keyword arguments so the **args doesn't get used. It's instead getting a third non-keyword argument (the dictionary). To fix that change the definition of the openX function.

def openX(filename, mode, kwargs):
    pass

I like Chad's answer, especially when the query results will be passed on to javascript in a browser. Javascript deals cleanly with numeric like entities as numbers but requires extra work to deal with numeric like entities as strings. i.e. must use parseInt or parseFloat on them.

Building on Chad's solution I use this and it is often exactly what I need and creates structures that can be JSON encoded for easy dealing with in javascript.

while ($row = $result->fetch_assoc()) {
    // convert numeric looking things to numbers for javascript
    foreach ($row as &$val) {
        if (is_numeric($val))
            $val = $val + 0;
    }
}

Adding a numeric string to 0 produces a numeric type in PHP and correctly identifies the type so floating point numbers will not be truncated into integers.

>> s = 'Smith'                                                          
=> "Smith"                                                              
>> s[0]                                                                 
=> "S"                                                        

You can modify Kendall Hopkins' answer a little in the switch statement to get a pretty clean looking and nicely indented printout by passing a json string into the following:

function prettyPrint( $json ){

$result = '';
$level = 0;
$in_quotes = false;
$in_escape = false;
$ends_line_level = NULL;
$json_length = strlen( $json );

for( $i = 0; $i < $json_length; $i++ ) {
    $char = $json[$i];
    $new_line_level = NULL;
    $post = "";
    if( $ends_line_level !== NULL ) {
        $new_line_level = $ends_line_level;
        $ends_line_level = NULL;
    }
    if ( $in_escape ) {
        $in_escape = false;
    } else if( $char === '"' ) {
        $in_quotes = !$in_quotes;
    } else if( ! $in_quotes ) {
        switch( $char ) {
            case '}': case ']':
                $level--;
                $ends_line_level = NULL;
                $new_line_level = $level;
                $char.="<br>";
                for($index=0;$index<$level-1;$index++){$char.="-----";}
                break;

            case '{': case '[':
                $level++;
                $char.="<br>";
                for($index=0;$index<$level;$index++){$char.="-----";}
                break;
            case ',':
                $ends_line_level = $level;
                $char.="<br>";
                for($index=0;$index<$level;$index++){$char.="-----";}
                break;

            case ':':
                $post = " ";
                break;

            case "\t": case "\n": case "\r":
                $char = "";
                $ends_line_level = $new_line_level;
                $new_line_level = NULL;
                break;
        }
    } else if ( $char === '\\' ) {
        $in_escape = true;
    }
    if( $new_line_level !== NULL ) {
        $result .= "\n".str_repeat( "\t", $new_line_level );
    }
    $result .= $char.$post;
}

echo "RESULTS ARE: <br><br>$result";
return $result;

}

Now just run the function prettyPrint( $your_json_string ); inline in your php and enjoy the printout. If you're a minimalist and don't like brackets for some reason, you can get rid of those easily by replacing the $char.="<br>"; with $char="<br>"; in the top three switch cases on $char.

I had the same problem when I missed to run:

git add .

(You must have at least one file, or you will get the error again.)

For me, I had changes already in place and I wanted the latest from the base branch. I was unable to do rebase, and cherry-pick would have taken forever, so I did the following:

git fetch origin <base branch name>  
git merge FETCH_HEAD

so in this case:

git fetch origin master  
git merge FETCH_HEAD

When setting your display to flex, you could simply use the flex property to mark which content can grow and which content cannot.

Flex property

div.content {_x000D_
 height: 300px;_x000D_
 display: flex;_x000D_
 flex-direction: column;_x000D_
}_x000D_
_x000D_
div.up {_x000D_
  flex: 1;_x000D_
}_x000D_
_x000D_
div.down {_x000D_
  flex: none;_x000D_
}

<div class="content">_x000D_
  <div class="up">_x000D_
    <h1>heading 1</h1>_x000D_
    <h2>heading 2</h2>_x000D_

I came across this post looking for a "shaking" implementation. millenomi's answer worked well for me, although i was looking for something that required a bit more "shaking action" to trigger. I've replaced to Boolean value with an int shakeCount. I also reimplemented the L0AccelerationIsShaking() method in Objective-C. You can tweak the ammount of shaking required by tweaking the ammount added to shakeCount. I'm not sure i've found the optimal values yet, but it seems to be working well so far. Hope this helps someone:

- (void)accelerometer:(UIAccelerometer *)accelerometer didAccelerate:(UIAcceleration *)acceleration {
    if (self.lastAcceleration) {
        if ([self AccelerationIsShakingLast:self.lastAcceleration current:acceleration threshold:0.7] && shakeCount >= 9) {
            //Shaking here, DO stuff.
            shakeCount = 0;
        } else if ([self AccelerationIsShakingLast:self.lastAcceleration current:acceleration threshold:0.7]) {
            shakeCount = shakeCount + 5;
        }else if (![self AccelerationIsShakingLast:self.lastAcceleration current:acceleration threshold:0.2]) {
            if (shakeCount > 0) {
                shakeCount--;
            }
        }
    }
    self.lastAcceleration = acceleration;
}

- (BOOL) AccelerationIsShakingLast:(UIAcceleration *)last current:(UIAcceleration *)current threshold:(double)threshold {
    double
    deltaX = fabs(last.x - current.x),
    deltaY = fabs(last.y - current.y),
    deltaZ = fabs(last.z - current.z);

    return
    (deltaX > threshold && deltaY > threshold) ||
    (deltaX > threshold && deltaZ > threshold) ||
    (deltaY > threshold && deltaZ > threshold);
}

PS: I've set the update interval to 1/15th of a second.

[[UIAccelerometer sharedAccelerometer] setUpdateInterval:(1.0 / 15)];

One difficulty is that the text, or description has line feeds. My clumsy kludge, to get it in something more tabular, is to add an HTML literal to the SELECT clause, copy and paste everything to notepad, save with an html extension, open in a browser, then copy and paste to a spreadsheet. example

SELECT obj.NAME AS TBL,trg.name,sm.definition,'<br>'
FROM SYS.OBJECTS obj
LEFT JOIN (SELECT trg1.object_id,trg1.parent_object_id,trg1.name FROM sys.objects trg1 WHERE trg1.type='tr' AND trg1.name like 'update%') trg
 ON obj.object_id=trg.parent_object_id
LEFT JOIN (SELECT sm1.object_id,sm1.definition FROM sys.sql_modules sm1 where sm1.definition like '%suser_sname()%') sm ON trg.object_id=sm.object_id
WHERE obj.type='u'
ORDER BY obj.name;

you may still need to fool around with tabs to get the description into one field, but at least it'll be on one line, which I find very helpful.

This does work for a specific delimiter for a specific amount of characters between the delimiter. I had many issues attempting to use this in a for each loop where the position changed but the delimiter was the same. For example I was using the backslash as the delimiter and wanted to only use everything to the right of the backslash. The issue was that once the position was defined (71 characters from the beginning) it would use $pos as 71 every time regardless of where the delimiter actually was in the script. I found another method of using a delimiter and .split to break things up then used the split variable to call the sections For instance the first section was $variable[0] and the second section was $variable[1].

vector.size() returns the size of a vector. You didn't put any string in the vector before the loop , so the size of the vector is 0. It will never enter the loop. First put some data in the vector and then try to add them. You can take input from the user for the number of string user wants to enter.

#include <iostream>
#include <vector>
#include <string>
#include <cctype>
using namespace std;


int main(int a, char* b [])
{
    vector<string> userString;
    string word;
    string sentence = "";
    int SIZE;
    cin>>SIZE;    //what will be the size of the vector
    for (int i = 0; i < SIZE; i++)
    {
        cin >> word;
        userString.push_back(word);
        sentence += userString[i] + " ";
    }
    cout << sentence;
    system("PAUSE");
    return 0;
}

another thing, actually you don't have to use a vector to do this.Two strings can do the job for you.

#include <iostream>
#include <vector>
#include <string>
#include <cctype>
using namespace std;


int main(int a, char* b [])
{
   // vector<string> userString;
    string word;
    string sentence = "";
    int SIZE;
    cin>>SIZE;    //what will be the size of the vector
    for (int i = 0; i < SIZE; i++)
    {
        cin >> word;
        sentence += word+ " ";
    }
    cout << sentence;
    system("PAUSE");
    return 0;
}

and if you want to enter string until the user wish , code will be like this:

#include <iostream>
#include <vector>
#include <string>
#include <cctype>
using namespace std;


int main(int a, char* b [])
{
   // vector<string> userString;
    string word;
    string sentence = "";
    //int SIZE;
    //cin>>SIZE;    //what will be the size of the vector
    while(cin>>word)
    {
        //cin >> word;
        sentence += word+ " ";
    }
    cout << sentence;
  //  system("PAUSE");
    return 0;
}

puts "string".split('').map(&:ord).to_s

this is to further clarify JD Isaaks answer ...

The problem you run into often is that you are using php to output html from many different php sources, and those sources are often, for whatever reason, outputting via different ways.

Sometimes you have literal html content that you want to directly output to the browser; other times the output is being dynamically created (server-side).

The dynamic content is always(?) going to be a string. Now you have to combine this stringified dynamic html with any literal, direct-to-display html ... into one meaningful html node structure.

This usually forces the developer to wrap all that direct-to-display content into a string (as JD Isaak was discussing) so that it can be properly delivered/inserted in conjunction with the dynamic html ... even though you don't really want it wrapped.

But by using ob_## methods you can avoid that string-wrapping mess. The literal content is, instead, output to the buffer. Then in one easy step the entire contents of the buffer (all your literal html), is concatenated into your dynamic-html string.

(My example shows literal html being output to the buffer, which is then added to a html-string ... look also at JD Isaaks example to see string-wrapping-of-html).

<?php // parent.php

//---------------------------------
$lvs_html  = "" ;

$lvs_html .= "<div>html</div>" ;
$lvs_html .= gf_component_assembler__without_ob( ) ;
$lvs_html .= "<div>more html</div>" ;

$lvs_html .= "----<br/>" ;

$lvs_html .= "<div>html</div>" ;
$lvs_html .= gf_component_assembler__with_ob( ) ;
$lvs_html .= "<div>more html</div>" ;

echo $lvs_html ;    
//    02 - component contents
//    html
//    01 - component header
//    03 - component footer
//    more html

//---------------------------------
function gf_component_assembler__without_ob( ) 
  { 
    $lvs_html  = "<div>01 - component header</div>" ; // <table ><tr>" ;
    include( "component_contents.php" ) ;
    $lvs_html .= "<div>03 - component footer</div>" ; // </tr></table>" ;

    return $lvs_html ;
  } ;

//---------------------------------
function gf_component_assembler__with_ob( ) 
  { 
    $lvs_html  = "<div>01 - component header</div>" ; // <table ><tr>" ;

        ob_start();
        include( "component_contents.php" ) ;
    $lvs_html .= ob_get_clean();

    $lvs_html .= "<div>03 - component footer</div>" ; // </tr></table>" ;

    return $lvs_html ;
  } ;

//---------------------------------
?>

<!-- component_contents.php -->
  <div>
    02 - component contents
  </div>

Try this ...

public class Solution {

  public static void main(String[] args) {
    long t = 1000;
    long sum = 0;

    for(int i = 1; i<t; i++){
            if(i%3 == 0 || i%5 == 0){
                sum = sum + i;
            }
        }
        System.out.println(sum);    
  }
}

Doing type('') is effectively equivalent to str and types.StringType

so type('') == str == types.StringType will evaluate to "True"

Note that Unicode strings which only contain ASCII will fail if checking types in this way, so you may want to do something like assert type(s) in (str, unicode) or assert isinstance(obj, basestring), the latter of which was suggested in the comments by 007Brendan and is probably preferred.

isinstance() is useful if you want to ask whether an object is an instance of a class, e.g:

class MyClass: pass

print isinstance(MyClass(), MyClass) # -> True
print isinstance(MyClass, MyClass()) # -> TypeError exception

But for basic types, e.g. str, unicode, int, float, long etc asking type(var) == TYPE will work OK.

If needing text input, the pattern works also

<input type="text" pattern="\d+">

For IntelliJ 2017:

Use "Problem" tool window to see all errors. This window appears in bottom/side tabs when you enable "automatic" build/make as mentioned by @pavan above (https://stackoverflow.com/a/45556424/828062).

To access this Problems panel, you must set your project to build automatically. Check the box for Preferences/Settings > Build, Execution, Deployment > Compiler > Build project automatically.

In addition, gcc will look in the directories specified after the -I option.

You can use the following command to clear out ALL variables. Be careful because it you cannot get your variables back.

rm(list=ls(all=TRUE))

Prior to PHP 5.3.6, the charset option was ignored. If you're running an older version of PHP, you must do it like this:

<?php

    $dbh = new PDO("mysql:$connstr",  $user, $password);

    $dbh -> exec("set names utf8");

?>

In addition to CMS´ answer you may want to consider putting the style in an external stylesheet and assign the style to the id, like this:

#divCheckbox {
display: none;
}

While this is usefull in rare cases (if that was not the case, the language would've allowed it directly), take a look at the Base from Member idiom. It's not a code free solution, you'd have to add an extra layer of inheritance, but it gets the job done. To avoid boilerplate code you could use boost's implementation

A simple solution is to wrap the query into a subselect with the ORDER statement first and applying the GROUP BY later:

SELECT * FROM ( 
    SELECT `timestamp`, `fromEmail`, `subject`
    FROM `incomingEmails` 
    ORDER BY `timestamp` DESC
) AS tmp_table GROUP BY LOWER(`fromEmail`)

This is similar to using the join but looks much nicer.

Using non-aggregate columns in a SELECT with a GROUP BY clause is non-standard. MySQL will generally return the values of the first row it finds and discard the rest. Any ORDER BY clauses will only apply to the returned column value, not to the discarded ones.

IMPORTANT UPDATE Selecting non-aggregate columns used to work in practice but should not be relied upon. Per the MySQL documentation "this is useful primarily when all values in each nonaggregated column not named in the GROUP BY are the same for each group. The server is free to choose any value from each group, so unless they are the same, the values chosen are indeterminate."

As of 5.7.5 ONLY_FULL_GROUP_BY is enabled by default so non-aggregate columns cause query errors (ER_WRONG_FIELD_WITH_GROUP)

As @mikep points out below the solution is to use ANY_VALUE() from 5.7 and above

See http://www.cafewebmaster.com/mysql-order-sort-group https://dev.mysql.com/doc/refman/5.6/en/group-by-handling.html https://dev.mysql.com/doc/refman/5.7/en/group-by-handling.html https://dev.mysql.com/doc/refman/5.7/en/miscellaneous-functions.html#function_any-value

I had a similar problem and google was sending me to this post. My solution was a bit different and less compact, but hopefully this can be useful to someone.

Showing your image with matplotlib.pyplot.imshow is generally a fast way to display 2D data. However this by default labels the axes with the pixel count. If the 2D data you are plotting corresponds to some uniform grid defined by arrays x and y, then you can use matplotlib.pyplot.xticks and matplotlib.pyplot.yticks to label the x and y axes using the values in those arrays. These will associate some labels, corresponding to the actual grid data, to the pixel counts on the axes. And doing this is much faster than using something like pcolor for example.

Here is an attempt at this with your data:

import matplotlib.pyplot as plt

# ... define 2D array hist as you did

plt.imshow(hist, cmap='Reds')
x = np.arange(80,122,2) # the grid to which your data corresponds
nx = x.shape[0]
no_labels = 7 # how many labels to see on axis x
step_x = int(nx / (no_labels - 1)) # step between consecutive labels
x_positions = np.arange(0,nx,step_x) # pixel count at label position
x_labels = x[::step_x] # labels you want to see
plt.xticks(x_positions, x_labels)
# in principle you can do the same for y, but it is not necessary in your case

Is this a commercial application or some hobbyist / open source software?

I'm asking this because in my experience, all free .NET Excel handling alternatives have serious problems, for different reasons. For hobbyist things, I usually end up porting jExcelApi from Java to C# and using it.

But if this is a commercial application, you would be better off by purchasing a third party library, like Aspose.Cells. Believe me, it totally worths it as it saves a lot of time and time ain't free.

With a small change of the markup, here's my approach (I've just inserted a span inside the paragraph):

.marquee {
  width: 450px;
  margin: 0 auto;
  overflow: hidden;
  box-sizing: border-box;
}

.marquee span {
  display: inline-block;
  width: max-content;

  padding-left: 100%;
  /* show the marquee just outside the paragraph */
  will-change: transform;
  animation: marquee 15s linear infinite;
}

.marquee span:hover {
  animation-play-state: paused
}


@keyframes marquee {
  0% { transform: translate(0, 0); }
  100% { transform: translate(-100%, 0); }
}


/* Respect user preferences about animations */

@media (prefers-reduced-motion: reduce) {
  .marquee span {
    animation-iteration-count: 1;
    animation-duration: 0.01; 
    /* instead of animation: none, so an animationend event is 
     * still available, if previously attached.
     */
    width: auto;
    padding-left: 0;
  }
}

<p class="marquee">
   <span>
       When I had journeyed half of our life's way, I found myself
       within a shadowed forest, for I had lost the path that 
       does not stray. – (Dante Alighieri, <i>Divine Comedy</i>. 
       1265-1321)
   </span>
   </p>

No hardcoded values — dependent on paragraph width — have been inserted.

The animation applies the CSS3 transform property (use prefixes where needed) so it performs well.

If you need to insert a delay just once at the beginning then also set an animation-delay. If you need instead to insert a small delay at every loop then try to play with an higher padding-left (e.g. 150%)

Activity.java:

public RecyclerView.LayoutManager mLayoutManager;

Parcelable state;

    mLayoutManager = new LinearLayoutManager(this);


// Inside `onCreate()` lifecycle method, put the below code :

    if(state != null) {
    mLayoutManager.onRestoreInstanceState(state);

    } 

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

        if (state != null) {
            mLayoutManager.onRestoreInstanceState(state);
        }
    }   

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

        state = mLayoutManager.onSaveInstanceState();

    }   

Why I'm using OnSaveInstanceState() in onPause() means, While switch to another activity onPause would be called.It will save that scroll position and restore the position when we coming back from another activity.

Both IP and DNS can be specified with the keytool additional argument -ext SAN=dns:abc.com,ip:1.1.1.1

Example:

keytool -genkeypair -keystore <keystore> -dname "CN=test, OU=Unknown, O=Unknown, L=Unknown, ST=Unknown, C=Unknown" -keypass <keypwd> -storepass <storepass> -keyalg RSA -alias unknown -ext SAN=dns:test.abc.com,ip:1.1.1.1

Its function depends on the builders that you have in your project (they can choose to interpret clean command however they like) and whether you have auto-build turned on. If auto-build is on, invoking clean is equivalent of a clean build. First artifacts are removed, then a full build is invoked. If auto-build is off, clean will remove the artifacts and stop. You can then invoke build manually later.

radian can also be converted to degree by using numpy

print(np.rad2deg(1))
57.29577951308232

if needed to roundoff ( I did with 6 digits after decimal below), then

print(np.round(np.rad2deg(1), 6)

57.29578

The command line tools are not included with the latest version of Grunt (0.4 at time of writing) instead you need to install them separately.

This is a good idea because it means you can have different versions of Grunt running on different projects but still use the nice concise grunt command to run them.

So first install the grunt cli tools globally:

npm install -g grunt-cli

(or possibly sudo npm install -g grunt-cli ).

You can establish that's working by typing grunt --version

Now you can install the current version of Grunt local to your project. So from your project's location...

npm install grunt --save-dev

The save-dev switch isn't strictly necessary but is a good idea because it will mark grunt in its package.json devDependencies section as a development only module.

If I start with a 3x4 array, and concatenate a 3x1 array, with axis 1, I get a 3x5 array:

In [911]: x = np.arange(12).reshape(3,4)
In [912]: np.concatenate([x,x[:,-1:]], axis=1)
Out[912]: 
array([[ 0,  1,  2,  3,  3],
       [ 4,  5,  6,  7,  7],
       [ 8,  9, 10, 11, 11]])
In [913]: x.shape,x[:,-1:].shape
Out[913]: ((3, 4), (3, 1))

Note that both inputs to concatenate have 2 dimensions.

Omit the :, and x[:,-1] is (3,) shape - it is 1d, and hence the error:

In [914]: np.concatenate([x,x[:,-1]], axis=1)
...
ValueError: all the input arrays must have same number of dimensions

The code for np.append is (in this case where axis is specified)

return concatenate((arr, values), axis=axis)

So with a slight change of syntax append works. Instead of a list it takes 2 arguments. It imitates the list append is syntax, but should not be confused with that list method.

In [916]: np.append(x, x[:,-1:], axis=1)
Out[916]: 
array([[ 0,  1,  2,  3,  3],
       [ 4,  5,  6,  7,  7],
       [ 8,  9, 10, 11, 11]])

np.hstack first makes sure all inputs are atleast_1d, and then does concatenate:

return np.concatenate([np.atleast_1d(a) for a in arrs], 1)

So it requires the same x[:,-1:] input. Essentially the same action.

np.column_stack also does a concatenate on axis 1. But first it passes 1d inputs through

array(arr, copy=False, subok=True, ndmin=2).T

This is a general way of turning that (3,) array into a (3,1) array.

In [922]: np.array(x[:,-1], copy=False, subok=True, ndmin=2).T
Out[922]: 
array([[ 3],
       [ 7],
       [11]])
In [923]: np.column_stack([x,x[:,-1]])
Out[923]: 
array([[ 0,  1,  2,  3,  3],
       [ 4,  5,  6,  7,  7],
       [ 8,  9, 10, 11, 11]])

All these 'stacks' can be convenient, but in the long run, it's important to understand dimensions and the base np.concatenate. Also know how to look up the code for functions like this. I use the ipython ?? magic a lot.

And in time tests, the np.concatenate is noticeably faster - with a small array like this the extra layers of function calls makes a big time difference.

This actually is possible, and I discovered how quite by accident while designing my first large-scale responsive design site.

<div class="wrapper">
  <div class="box">
    <img src="/logo.png" alt="">
  </div>
</div>

.wrapper { position:relative; overflow:hidden; }

.box { float:left; } //Note: 'float:right' would work too

.box > img { width:50%; }

The overflow:hidden gives the wrapper height and width, despite the floating contents, without using the clearfix hack. You can then position your content using margins. You can even make the wrapper div an inline-block.

Ex Microsoft Developer's Opinion

I worked on a core team for the MSDN website. Now, I use c# razor for ecommerce sites with my programming team and we focus heavy on jQuery front end with back end c# razor pages and LINQ-Entity memory database so the pages are 1-2 millisecond response times even on nested for loops with queries and no page caching. We don't use MVC, just plain ASP.NET with razor pages being mapped with URL Rewrite module for IIS 7, no ASPX pages or ViewState or server-side event programming at all. It doesn't have the extra (unnecessary) layers MVC puts in code constructs for the regex challenged. Less is more for us. Its all lean and mean but I give props to MVC for its testability but that's all.

Razor pages have no event life cycle like ASPX pages. Its just rendering as one requested page. C# is such a great language and Razor gets out of its way nicely to let it do its job. The anonymous typing with generics and linq make life so easy with c# and razor pages. Using Razor pages will help you think and code lighter.

One of the drawback of Razor and MVC is there is no ViewState-like persistence. I needed to implement a solution for that so I ended up writing a jQuery plugin for that here -> http://www.jasonsebring.com/dumbFormState which is an HTML 5 offline storage supported plugin for form state that is working in all major browsers now. It is just for form state currently but you can use window.sessionStorage or window.localStorage very simply to store any kind of state across postbacks or even page requests, I just bothered to make it autosave and namespace it based on URL and form index so you don't have to think about it.

        if t[1] > 12:
            t[0] += 1 + int(months / 12)

The answer is: you can't only through sms, i have tried that approach before.

You could fetch the base station IDs, but this won't help you a lot without the location of the base station itself and this informations are really hard to retrieve from the providers.

I have looked through the 3 apps you have listed in your question:

1. The App uses WiFi and GPRS location service, quite the same approach as Google uses on the phone. phonesavvy maybe has a base station location database or uses a database retrieved e.g. from OpenStreetMap or some similar crowd-based project.
2. The app analyzes just the number for country code and city code. No location there.
3. Dito.

You can save your graph as svg for a lossless quality:

import matplotlib.pylab as plt

x = range(10)

plt.figure()
plt.plot(x,x)
plt.savefig("graph.svg")

You have to create __init__.py on the Models subfolder. The file may be empty. It defines a package.

Then you can do:

from Models.user import User

Read all about it in python tutorial, here.

There is also a good article about file organization of python projects here.

Since in option 1 the message string is a constant, there is absolutely no gain in wrapping the logging statement with a condition, on the contrary, if the log statement is debug enabled, you will be evaluating twice, once in the isDebugEnabled() method and once in debug() method. The cost of invoking isDebugEnabled() is in the order of 5 to 30 nanoseconds which should be negligible for most practical purposes. Thus, option 2 is not desirable because it pollutes your code and provides no other gain.

Most of the answers won't catch it (presumably) if you use <label for="cbId">cb name</label>. This means when you click the label it will check the box instead of directly clicking on the checkbox. (Not exactly the question, but various search results tend to come here)

<div id="OuterDivOrBody">
    <input type="checkbox" id="checkbox1" />
    <label for="checkbox1">Checkbox label</label>
    <br />
    <br />
    The confirm result:
    <input type="text" id="textbox1" />
</div>

In which case you could use:

Earlier versions of jQuery:

$('#OuterDivOrBody').delegate('#checkbox1', 'change', function () {
    // From the other examples
    if (!this.checked) {
        var sure = confirm("Are you sure?");
        this.checked = !sure;
        $('#textbox1').val(sure.toString());
    }
});

JSFiddle example with jQuery 1.6.4

jQuery 1.7+

$('#checkbox1').on('change', function() { 
    // From the other examples
    if (!this.checked) {
        var sure = confirm("Are you sure?");
        this.checked = !sure;
        $('#textbox1').val(sure.toString());
    }
});

No compiler worth its weight in salt will run differently between

for(int i=0; i<10; i++)

and

for(int i=0;i<10;++i)

++i and i++ have the same cost. The only thing that differs is that the return value of ++i is i+1 whereas the return value of i++ is i.

So for those prefering ++i, there's probably no valid justification, just personal preference.

EDIT: This is wrong for classes, as said in about every other post. i++ will generate a copy if i is a class.

another solution is to override the join operator of the str class.

Let us define a new class my_string as follows

class my_string(str):
    def join(self, l):
        l_tmp = [str(x) for x in l]
        return super(my_string, self).join(l_tmp)

Then you can do

class Obj:
    def __str__(self):
        return 'name'

list = [Obj(), Obj(), Obj()]
comma = my_string(',')

print comma.join(list)

and you get

name,name,name

BTW, by using list as variable name you are redefining the list class (keyword) ! Preferably use another identifier name.

Hope you'll find my answer useful.

You can try this.

String s = new String(bytearray);

I fixed this error by adding the name="fieldName" ngDefaultControl attributes to the element that carries the [(ngModel)] attribute.

Put this line in an htaccess file in the directory you want the setting to be enabled:

php_value allow_url_fopen On

Note that this setting will only apply to PHP file's in the same directory as the htaccess file.

As an alternative to using url_fopen, try using curl.

If you just want to snag the schema and make an empty table out of it, use a false predicate, like so:

SELECT * INTO myNewTable FROM myView WHERE 1=2

The variable set by varStatus is a LoopTagStatus object, not an int. Use:

<div id="divIDNo${theCount.index}">

To clarify:

• ${theCount.index} starts counting at 0 unless you've set the begin attribute
• ${theCount.count} starts counting at 1

BackgroundTint works as color filter.

Try to run the server at a different port. Worked for me:

python manage.py runserver 127.0.0.1:7000

Explanation:

as mentioned on Django documentation:

If you run this script as a user with normal privileges (recommended), you might not have access to start a port on a low port number. Low port numbers are reserved for the superuser (root).

This server uses the WSGI application object specified by the WSGI_APPLICATION setting.

DO NOT USE THIS SERVER IN A PRODUCTION SETTING. It has not gone through security audits or performance tests. (And that’s how it’s gonna stay. We’re in the business of making Web frameworks, not Web servers, so improving this server to be able to handle a production environment is outside the scope of Django.)

In my case I got this message because there's a special char (&) in my connectionstring, remove it then everything's good.

You should be careful when using the ROW_NUMBER() OVER (ORDER BY) statement as performance is quite poor. Same goes for using Common Table Expressions with ROW_NUMBER() that is even worse. I'm using the following snippet that has proven to be slightly faster than using a table variable with an identity to provide the page number.

DECLARE @Offset INT = 120000
DECLARE @Limit INT = 10

DECLARE @ROWCOUNT INT = @Offset+@Limit
SET ROWCOUNT @ROWCOUNT

SELECT * FROM MyTable INTO #ResultSet
WHERE MyTable.Type = 1

SELECT * FROM
(
    SELECT *, ROW_NUMBER() OVER(ORDER BY SortConst ASC) As RowNumber FROM
    (
        SELECT *, 1 As SortConst FROM #ResultSet
    ) AS ResultSet
) AS Page
WHERE RowNumber BETWEEN @Offset AND @ROWCOUNT

DROP TABLE #ResultSet

The easiest way to communicate between your activity and fragments is using interfaces. The idea is basically to define an interface inside a given fragment A and let the activity implement that interface.

Once it has implemented that interface, you could do anything you want in the method it overrides.

The other important part of the interface is that you have to call the abstract method from your fragment and remember to cast it to your activity. It should catch a ClassCastException if not done correctly.

There is a good tutorial on Simple Developer Blog on how to do exactly this kind of thing.

I hope this was helpful to you!

user2532030's answer is the correct and most simple answer.

I just want to add, that in the case, where the value of the determining cell is not suitable for a RegEx-match, I found the following syntax to work the same, only with numerical values, relations et.c.:

[Custom formula is]
=$B$2:$B = "Complete"
Range: A2:Z1000

If column 2 of any row (row 2 in script, but the leading $ means, this could be any row) textually equals "Complete", do X for the Range of the entire sheet (excluding header row (i.e. starting from A2 instead of A1)).

But obviously, this method allows also for numerical operations (even though this does not apply for op's question), like:

=$B$2:$B > $C$2:$C

So, do stuff, if the value of col B in any row is higher than col C value.

One last thing: Most likely, this applies only to me, but I was stupid enough to repeatedly forget to choose Custom formula is in the drop-down, leaving it at Text contains. Obviously, this won't float...

Using array or set comparisons:

create table t (str text);
insert into t values ('AAA'), ('BBB'), ('DDD999YYY'), ('DDD099YYY');

select str from t
where str like any ('{"AAA%", "BBB%", "CCC%"}');

select str from t
where str like any (values('AAA%'), ('BBB%'), ('CCC%'));

It is also possible to do an AND which would not be easy with a regex if it were to match any order:

select str from t
where str like all ('{"%999%", "DDD%"}');

select str from t
where str like all (values('%999%'), ('DDD%'));

Technically, const is not part of the ECMAScript specification. Also, using the "CommonJS Module" pattern you've noted, you can change the value of that "constant" since it's now just an object property. (not sure if that'll cascade any changes to other scripts that require the same module, but it's possible)

To get a real constant that you can also share, check out Object.create, Object.defineProperty, and Object.defineProperties. If you set writable: false, then the value in your "constant" cannot be modified. :)

It's a little verbose, (but even that can be changed with a little JS) but you should only need to do it once for your module of constants. Using these methods, any attribute that you leave out defaults to false. (as opposed to defining properties via assignment, which defaults all the attributes to true)

So, hypothetically, you could just set value and enumerable, leaving out writable and configurable since they'll default to false, I've just included them for clarity.

Update - I've create a new module (node-constants) with helper functions for this very use-case.

constants.js -- Good

Object.defineProperty(exports, "PI", {
    value:        3.14,
    enumerable:   true,
    writable:     false,
    configurable: false
});

constants.js -- Better

function define(name, value) {
    Object.defineProperty(exports, name, {
        value:      value,
        enumerable: true
    });
}

define("PI", 3.14);

script.js

var constants = require("./constants");

console.log(constants.PI); // 3.14
constants.PI = 5;
console.log(constants.PI); // still 3.14

You can use COM, or P/Invoke from .Net, to open the Winspool.drv driver and send bytes directly to devices. But you don't want to do that; this typically works only for the one device on the one version of the one driver you test with, and breaks on everything else. Take this from long, painful, personal experience.

What you want to do is get a barcode font or library that draws barcodes using plain old GDI or GDI+ commands; there's one for .Net here. This works on all devices, even after Zebra changes the driver.

There is no ternary operator in kotlin, as the if else block returns value

so, you can do: val max = if (a > b) a else b instead of java's max = (a > b) ? b : c

We can also use when construction, it also return value:

val max = when(a > b) {
    true -> a
    false -> b
}

Here is link for kotlin documentation : Control Flow: if, when, for, while

If you want to create a garage and fill it up with new cars that can be accessed later, use this code:

for (int i = 0; i < garage.length; i++)
     garage[i] = new Car("argument");

Also, the cars are later accessed using:

garage[0];
garage[1];
garage[2];
etc.

This error is because of multiple project having the offending resources.

Try out adding the dependencies projects other way around. (like in pom.xml or external depandancies)

You can use the ATL text conversion macros to convert a narrow (char) string to a wide (wchar_t) one. For example, to convert a std::string:

#include <atlconv.h>
...
std::string str = "Hello, world!";
CA2W pszWide(str.c_str());
loadU(pszWide);

You can also specify a code page, so if your std::string contains UTF-8 chars you can use:

CA2W pszWide(str.c_str(), CP_UTF8);

Very useful but Windows only.

Here is my simplistic approach. I am using the classic builder pattern for this. It is typesafe (no boxing/unboxing) and also compatbile with .NET 2.0 (no extension methods etc.).

It is used like this:

public override int GetHashCode()
{
    HashBuilder b = new HashBuilder();
    b.AddItems(this.member1, this.member2, this.member3);
    return b.Result;
} 

And here is the acutal builder class:

internal class HashBuilder
{
    private const int Prime1 = 17;
    private const int Prime2 = 23;
    private int result = Prime1;

    public HashBuilder()
    {
    }

    public HashBuilder(int startHash)
    {
        this.result = startHash;
    }

    public int Result
    {
        get
        {
            return this.result;
        }
    }

    public void AddItem<T>(T item)
    {
        unchecked
        {
            this.result = this.result * Prime2 + item.GetHashCode();
        }
    }

    public void AddItems<T1, T2>(T1 item1, T2 item2)
    {
        this.AddItem(item1);
        this.AddItem(item2);
    }

    public void AddItems<T1, T2, T3>(T1 item1, T2 item2, T3 item3)
    {
        this.AddItem(item1);
        this.AddItem(item2);
        this.AddItem(item3);
    }

    public void AddItems<T1, T2, T3, T4>(T1 item1, T2 item2, T3 item3, 
        T4 item4)
    {
        this.AddItem(item1);
        this.AddItem(item2);
        this.AddItem(item3);
        this.AddItem(item4);
    }

    public void AddItems<T1, T2, T3, T4, T5>(T1 item1, T2 item2, T3 item3, 
        T4 item4, T5 item5)
    {
        this.AddItem(item1);
        this.AddItem(item2);
        this.AddItem(item3);
        this.AddItem(item4);
        this.AddItem(item5);
    }        

    public void AddItems<T>(params T[] items)
    {
        foreach (T item in items)
        {
            this.AddItem(item);
        }
    }
}

try this:

select convert (date ,getdate())

or

select CAST (getdate() as DATE)

or

select convert(varchar(10), getdate(),121)

The answer was:

heroku restart -a app_name

# The -a is the same as --app

Easily aliased with alias hra='heroku restart --app '
Which you can make a permanent alias by adding it to your .bashrc or .bash_aliases file as described at: https://askubuntu.com/questions/17536/how-do-i-create-a-permanent-bash-alias and
Creating permanent executable aliases
Then you can just type hra app_name

You can restart a specific remote, e.g. "staging" with:

heroku restart -a app_name -r remote_name

Alternatively if you are in the root directory of your rails application you can just type

heroku restart

to restart that app and and you can create an easy alias for that with

alias hr='heroku restart'`

You can place these aliases in your .bashrc file or (preferred) in a .bash_aliases file which is called from .bashrc

With SQL Server try:

SELECT TOP 1 * FROM dbo.youTable WHERE user_id = 'userid' ORDER BY date_added desc

The logic is not flawed. The statement

if x is y then x==y is also True

should never be read to mean

if x==y then x is y

It is a logical error on the part of the reader to assume that the converse of a logic statement is true. See http://en.wikipedia.org/wiki/Converse_(logic)

I had this happen in Visual Studio 2015 too for an interesting reason. Just adding it here in case it happens to someone else.

I already had number of files in project and I was adding another one that would have main function in it, however when I initially added the file I made a typo in the extension (.coo instead of .cpp). I corrected that but when I was done I got this error. It turned out that Visual Studio was being smart and when file was added it decided that it is not a source file due to the initial extension.

Right-clicking on file in solution explorer and selecting Properties -> General -> ItemType and setting it to "C/C++ compiler" fixed the issue.

as I expected, yeah, it's because the whole DOM element is being pushed down. You have multiple options. You can put the buttons in separate divs, and float them so that they don't affect each other. the simpler solution is to just set the :active button to position:relative; and use top instead of margin or line-height. example fiddle: http://jsfiddle.net/5CZRP/

The default values for minOccurs and maxOccurs are 1. Thus:

<xsd:element minOccurs="1" name="asdf"/>

cardinality is [1-1] Note: if you specify only minOccurs attribute, it can't be greater than 1, because the default value for maxOccurs is 1.

<xsd:element minOccurs="5" maxOccurs="2" name="asdf"/>

invalid

<xsd:element maxOccurs="2" name="asdf"/>

cardinality is [1-2] Note: if you specify only maxOccurs attribute, it can't be smaller than 1, because the default value for minOccurs is 1.

<xsd:element minOccurs="0" maxOccurs="0"/>

is a valid combination which makes the element prohibited.

Blowfish isn't better than MD5 or SHA512, as they serve different purposes. MD5 and SHA512 are hashing algorithms, Blowfish is an encryption algorithm. Two entirely different cryptographic functions.

The ConfigurationManager is not what you need to access your own settings.

To do this you should use

{YourAppName}.Properties.Settings.{settingName}

You can of course format the result of current_timestamp(). Please have a look at the various formatting functions in the official documentation.

Still anyone have this problem, use following code inside your form as below.

 echo '<input type = "hidden" name = "_token" value = "'. csrf_token().'" >';

I used a trial version of ZOC Terminal Emulator and it worked. It readily accepts the Amazon's *.pem files.

The trick is though, that you need to specify "ec2-user" instead of "root" for the username - despite the example shown in the EC2 console, which is wrong! ;-)

You can also put DOM elements, like div on top of the canvas that would represent your canvas elements and be positioned the same way.

Now you can attach event listeners to these divs and run the necessary actions.

I've tried out many answers on this page, none really worked:

• org.hamcrest.CoreMatchers.containsString does not compile, cannot resolve method.
• JUnitMatchers.containsString is depricated (and refers to CoreMatchers.containsString).
• org.hamcrest.Matchers.containsString: NoSuchMethodError

So instead of writing readable code, I decided to use the simple and workable approach mentioned in the question instead.

Hopefully another solution will come up.

I set the below 3 styles to my img tag

max-height: 500px;
height: 70%;
width: auto;

What it does that for desktop screen img doesn't grow beyond 500px but for small mobile screens, it will shrink to 70% of the outer container. Works like a charm.

It also works width property.

Delete the .keyring file under the location: configuration\org.eclipse.core.runtime, and after that, you will be invited to prompt your new svn account.

If you have only put (non-null) String references in the JComboBox, then either way is fine.

However, the first solution would also allow for future modifications in which you insert Integers, Doubless, LinkedLists etc. as items in the combo box.

To be robust against null values (still without casting) you may consider a third option:

String x = String.valueOf(JComboBox.getSelectedItem());

You can use class .center-block in combination with style="width:400px;max-width:100%;" to preserve responsiveness.

Using .col-md-* class with .center-block will not work because of the float on .col-md-*.

You can use a custom dialog.

Custom dialog layout. list.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">
    <ListView
        android:id="@+id/lv"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"/>
</LinearLayout>

In your activity

Dialog dialog = new Dialog(Activity.this);
       dialog.setContentView(R.layout.list)

ListView lv = (ListView ) dialog.findViewById(R.id.lv);
dialog.setCancelable(true);
dialog.setTitle("ListView");
dialog.show();

Edit:

Using alertdialog

String names[] ={"A","B","C","D"};
AlertDialog.Builder alertDialog = new AlertDialog.Builder(MainActivity.this);
LayoutInflater inflater = getLayoutInflater();
View convertView = (View) inflater.inflate(R.layout.custom, null);
alertDialog.setView(convertView);
alertDialog.setTitle("List");
ListView lv = (ListView) convertView.findViewById(R.id.lv);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,names);
lv.setAdapter(adapter);
alertDialog.show();

custom.xml

<?xml version="1.0" encoding="utf-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/listView1"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

</ListView>

Try my chiliadic arithmetic library, which you can see here. If you want a later version, I can get you one.

If you don't have Your own Data Class, then you can design your map as follows

Map<Integer, Object> map=new HashMap<Integer, Object>();

Here don't forget to use "instanceof" operator while retrieving the values from MAP.

If you have your own Data class then then you can design your map as follows

Map<Integer, YourClassName> map=new HashMap<Integer, YourClassName>();

import java.util.Date;
import java.util.HashMap;
import java.util.Map;
import java.util.Set;


public class HashMapTest {
public static void main(String[] args) {
    Map<Integer,Demo> map=new HashMap<Integer, Demo>();
    Demo d1= new Demo(1,"hi",new Date(),1,1);
    Demo d2= new Demo(2,"this",new Date(),2,1);
    Demo d3= new Demo(3,"is",new Date(),3,1);
    Demo d4= new Demo(4,"mytest",new Date(),4,1);
    //adding values to map
    map.put(d1.getKey(), d1);
    map.put(d2.getKey(), d2);
    map.put(d3.getKey(), d3);
    map.put(d4.getKey(), d4);
    //retrieving values from map
    Set<Integer> keySet= map.keySet();
    for(int i:keySet){
        System.out.println(map.get(i));
    }
    //searching key on map
    System.out.println(map.containsKey(d1.getKey()));
    //searching value on map
    System.out.println(map.containsValue(d1));
}

}
class Demo{
    private int key;
    private String message;
    private Date time;
    private int count;
    private int version;

    public Demo(int key,String message, Date time, int count, int version){
        this.key=key;
        this.message = message;
        this.time = time;
        this.count = count;
        this.version = version;
    }
    public String getMessage() {
        return message;
    }
    public Date getTime() {
        return time;
    }
    public int getCount() {
        return count;
    }
    public int getVersion() {
        return version;
    }
    public int getKey() {
        return key;
    }
    @Override
    public String toString() {
        return "Demo [message=" + message + ", time=" + time
                + ", count=" + count + ", version=" + version + "]";

Correction for What does it mean to bind a multicast (udp) socket? as long as it partially true at the following quote:

The "bind" operation is basically saying, "use this local UDP port for sending and receiving data. In other words, it allocates that UDP port for exclusive use for your application

There is one exception. Multiple applications can share the same port for listening (usually it has practical value for multicast datagrams), if the SO_REUSEADDR option applied. For example

int sock = socket(AF_INET, SOCK_DGRAM, IPPROTO_UDP); // create UDP socket somehow
...
int set_option_on = 1;
// it is important to do "reuse address" before bind, not after
int res = setsockopt(sock, SOL_SOCKET, SO_REUSEADDR, (char*) &set_option_on, 
    sizeof(set_option_on));
res = bind(sock, src_addr, len);

If several processes did such "reuse binding", then every UDP datagram received on that shared port will be delivered to each of the processes (providing natural joint with multicasts traffic).

Here are further details regarding what happens in a few cases:

1. attempt of any bind ("exclusive" or "reuse") to free port will be successful

2. attempt to "exclusive binding" will fail if the port is already "reuse-binded"

3. attempt to "reuse binding" will fail if some process keeps "exclusive binding"

I have Visual Studio 2013 Express. I had to delete the registry key under:

hkey_current_user\software\Microsoft\VSCommon\12.\clientservices\tokenstorge\VWDExpress\ideuser

Try this:

printf '\n%s\n' 'I want this on a new line!'

That allows you to separate the formatting from the actual text. You can use multiple placeholders and multiple arguments.

quantity=38; price=142.15; description='advanced widget'
$ printf '%8d%10.2f  %s\n' "$quantity" "$price" "$description"
      38    142.15  advanced widget

The answer that the OP accepted is wildly different from the question I thought was asked. I thought the OP wanted a way to auto-align = signs or + signs, similar to the tabularize plugin for vim.

For this task, I found the Columns4Eclipse plugin to be just what I needed.

ALTER SCHEMA NewSchema TRANSFER [OldSchema].[TableName]

I always have to use the brackets when I use the ALTER SCHEMA query in SQL, or I get an error message.

public Boolean addArtist(String artistName){

        SQLiteDatabase db= getWritableDatabase();

        ContentValues data=new ContentValues();
        data.put(ArtistMaster.ArtistDetails.COLUMN_ARTIST_NAME,artistName);
        long id = db.insert(ArtistMaster.ArtistDetails.TABLE_NAME,null,data);

        if(id>0){
            return true;
        }else{
            return false;
        }
    }

It says right there in the output of git status:

#   (use "git add/rm <file>..." to update what will be committed)

so just do:

git rm <filename>

WebSphere Application Server V7 does support Java Platform, Standard Edition (Java SE) 6 (see Specifications and API documentation in the Network Deployment (All operating systems), Version 7.0 Information Center) and it's since the release V8.5 when Java 7 has been supported.

I couldn't find the Java 6 SDK documentation, and could only consult IBM JVM Messages in Java 7 Windows documentation. Alas, I couldn't find the error message in the documentation either.

Since java.lang.UnsupportedClassVersionError is "Thrown when the Java Virtual Machine attempts to read a class file and determines that the major and minor version numbers in the file are not supported.", you ran into an issue of building the application with more recent version of Java than the one supported by the runtime environment, i.e. WebSphere Application Server 7.0.

I may be mistaken, but I think that offset=6 in the message is to let you know what position caused the incompatibility issue to occur. It's irrelevant for you, for me, and for many other people, but some might find it useful, esp. when they generate bytecode themselves.

If the below statment is present in your class then your log4j.properties should be in java source(src) folder , if it is jar executable it should be packed in jar not a seperate file.

Thanks,

The templatemaker utility from Adrian Holovaty (of Django fame) uses a very interesting approach: You feed it variations of the same page and it "learns" where the "holes" for variable data are. It's not HTML specific, so it would be good for scraping any other plaintext content as well. I've used it also for PDFs and HTML converted to plaintext (with pdftotext and lynx, respectively).

My Spring Data JPA-based answer: I simply added a @Transactional annotation to my outer method.

Why it works

The child entity was immediately becoming detached because there was no active Hibernate Session context. Providing a Spring (Data JPA) transaction ensures a Hibernate Session is present.

Reference:

https://vladmihalcea.com/a-beginners-guide-to-jpa-hibernate-entity-state-transitions/

Yep, but you have to put the array first in the expression:

... | where { @("user1","user2") -notlike $_.username }

-Oisin

Or like this:

Code::whereNotIn('to_be_used_by_user_id', [2])->get();

Swiss Army Knife: GroupBy.describe

Returns count, mean, std, and other useful statistics per-group.

df.groupby(['A', 'B'])['C'].describe()

           count  mean   std   min   25%   50%   75%   max
A   B                                                     
bar one      1.0  0.40   NaN  0.40  0.40  0.40  0.40  0.40
    three    1.0  2.24   NaN  2.24  2.24  2.24  2.24  2.24
    two      1.0 -0.98   NaN -0.98 -0.98 -0.98 -0.98 -0.98
foo one      2.0  1.36  0.58  0.95  1.15  1.36  1.56  1.76
    three    1.0 -0.15   NaN -0.15 -0.15 -0.15 -0.15 -0.15
    two      2.0  1.42  0.63  0.98  1.20  1.42  1.65  1.87

To get specific statistics, just select them,

df.groupby(['A', 'B'])['C'].describe()[['count', 'mean']]

           count      mean
A   B                     
bar one      1.0  0.400157
    three    1.0  2.240893
    two      1.0 -0.977278
foo one      2.0  1.357070
    three    1.0 -0.151357
    two      2.0  1.423148

describe works for multiple columns (change ['C'] to ['C', 'D']—or remove it altogether—and see what happens, the result is a MultiIndexed columned dataframe).

You also get different statistics for string data. Here's an example,

df2 = df.assign(D=list('aaabbccc')).sample(n=100, replace=True)

with pd.option_context('precision', 2):
    display(df2.groupby(['A', 'B'])
               .describe(include='all')
               .dropna(how='all', axis=1))

              C                                                   D                
          count  mean       std   min   25%   50%   75%   max count unique top freq
A   B

pandas >= 1.1: DataFrame.value_counts

This is available from pandas 1.1 if you just want to capture the size of every group, this cuts out the GroupBy and is faster.

df.value_counts(subset=['col1', 'col2'])

Minimal Example

# Setup
np.random.seed(0)
df = pd.DataFrame({'A' : ['foo', 'bar', 'foo', 'bar',
                          'foo', 'bar', 'foo', 'foo'],
                   'B' : ['one', 'one', 'two', 'three',
                          'two', 'two', 'one', 'three'],
                   'C' : np.random.randn(8),
                   'D' : np.random.randn(8)})

df.value_counts(['A', 'B']) 

A    B    
foo  two      2
     one      2
     three    1
bar  two      1
     three    1
     one      1

I was trying to see if the same thing was happening to pip, and saw that pip was broken. Did some digging and realized it's probably caused by Homebrew deleted python@2 on February 1st, 2020.

Running brew uninstall python@2 to delete python2 installed by Homebrew.

Destroyed the virtual env created using python3 and created a new one.
pip3 installing works fine again.

• int to Hex :

  Integer.toHexString(intValue);
  

• Hex to int :

  Integer.valueOf(hexString, 16).intValue();
  

You may also want to use long instead of int (if the value does not fit the int bounds):

• Hex to long:

  Long.valueOf(hexString, 16).longValue()
  

• long to Hex

  Long.toHexString(longValue)
  

Wouldn't you just do:

srand(time(NULL));
int r = ( rand() % 6 ) + 1;

% is the modulus operator. Essentially it will just divide by 6 and return the remainder... from 0 - 5

Apparently - as I recently learned - this is the fastest way to do it:

var objs = {...};
var objKeys = Object.keys(obj);
for (var i = 0, objLen = objKeys.length; i < objLen; i++) {
    // do whatever in here
    var obj = objs[objKeys[i]];
}

there are four types of strings available in php. They are single quotes ('), double quotes (") and Nowdoc (<<<'EOD') and heredoc(<<<EOD) strings

you can use both single quotes and double quotes inside heredoc string. Variables will be expanded just as double quotes.

nowdoc strings will not expand variables just like single quotes.

Here's the implementation in JOSM:

/**
 * Returns the Java version as an int value.
 * @return the Java version as an int value (8, 9, etc.)
 * @since 12130
 */
public static int getJavaVersion() {
    String version = System.getProperty("java.version");
    if (version.startsWith("1.")) {
        version = version.substring(2);
    }
    // Allow these formats:
    // 1.8.0_72-ea
    // 9-ea
    // 9
    // 9.0.1
    int dotPos = version.indexOf('.');
    int dashPos = version.indexOf('-');
    return Integer.parseInt(version.substring(0,
            dotPos > -1 ? dotPos : dashPos > -1 ? dashPos : 1));
}

I just found another method by mistake :

What I did was to declare a var db = null above app declaration and then modified it in the app.js then when I accessed it in the controller.js I was able to access it without any problem.There might be some issues with this method which I'm not aware of but It's a good solution I guess.

I recently ran into the same problem but the issue wasn't related to tabs and spaces but an odd Unicode character that appeared invisible to the eye in my IDE. Eventually, I isolated the problem and typed out the line exactly as it was and checked the git diff:

If you are able to isolate the line before the reported line and type it out again, you might find that it solves your problem. Won't tell you why it happened in the first place, but it at least gets rid of the issue.

I figured out what it was! When I cleared the fields using the each() method, it also cleared the hidden field which the php needed to run:

if ($_POST['action'] == 'addRunner') 

I used the :not() on the selection to stop it from clearing the hidden field.

I would recommend a combination of PatIndex and Left. Carefully constructed, you can write a query that always works, no matter what your data looks like.

Ex:

Declare @Temp Table(Data VarChar(20))

Insert Into @Temp Values('BTA200')
Insert Into @Temp Values('BTA50')
Insert Into @Temp Values('BTA030')
Insert Into @Temp Values('BTA')
Insert Into @Temp Values('123')
Insert Into @Temp Values('X999')

Select Data, Left(Data, PatIndex('%[0-9]%', Data + '1') - 1)
From   @Temp

PatIndex will look for the first character that falls in the range of 0-9, and return it's character position, which you can use with the LEFT function to extract the correct data. Note that PatIndex is actually using Data + '1'. This protects us from data where there are no numbers found. If there are no numbers, PatIndex would return 0. In this case, the LEFT function would error because we are using Left(Data, PatIndex - 1). When PatIndex returns 0, we would end up with Left(Data, -1) which returns an error.

There are still ways this can fail. For a full explanation, I encourage you to read:

Extracting numbers with SQL Server

That article shows how to get numbers out of a string. In your case, you want to get alpha characters instead. However, the process is similar enough that you can probably learn something useful out of it.

As for now, we should develop Material Design practice. In this case you could add a ripple effect on an ImageView.

Go to the Declaration of the desired object and mark it Shared.

You can use %~dp0 to get the path of the currently running batch file.

Edited to change directory to the VBS location before running

If you want the VBS to synchronously run in the same window, then

@echo off
pushd %~dp0
cscript necdaily.vbs

If you want the VBS to synchronously run in a new window, then

@echo off
pushd %~dp0
start /wait "" cmd /c cscript necdaily.vbs

If you want the VBS to asynchronously run in the same window, then

@echo off
pushd %~dp0
start /b "" cscript necdaily.vbs

If you want the VBS to asynchronously run in a new window, then

@echo off
pushd %~dp0
start "" cmd /c cscript necdaily.vbs

Method that works nicely in Safari. Also works in Firefox and Opera, but with a warning.

Another option is to use SqlBulkTools available from Nuget. It's very easy to use and has some powerful features.

Example:

var bulk = new BulkOperations();
var books = GetBooks();

using (TransactionScope trans = new TransactionScope())
{
    using (SqlConnection conn = new SqlConnection(ConfigurationManager
    .ConnectionStrings["SqlBulkToolsTest"].ConnectionString))
    {
        bulk.Setup<Book>()
            .ForCollection(books)
            .WithTable("Books") 
            .AddAllColumns()
            .BulkInsert()
            .Commit(conn);
    }

    trans.Complete();
}

See the documentation for more examples and advanced usage. Disclaimer: I am the author of this library and any views are of my own opinion.

Maybe this helps someone:

git tag 0.0.1                    # creates tag locally     
git push origin 0.0.1            # pushes tag to remote

git tag --delete 0.0.1           # deletes tag locally    
git push --delete origin 0.0.1   # deletes remote tag

On Windows XP the path to the .gemrc file is

c:\Documents and Settings\All Users\Application Data\gemrc 

and this file is not created by default, you should create it yourself.

If you are using SQL Express (which you are), then your login credentials are .\SQLEXPRESS

Here is the connectionString in the web config file which you can add:

<connectionStrings>
<add connectionString="Server=localhost\SQLEXPRESS;Database=yourDBName;Initial Catalog= yourDBName;Integrated Security=true" name="nametoCallBy" providerName="System.Data.SqlClient"/>
</connectionStrings>

Place is just above the system.web tag.

Then you can call it by:

connString = ConfigurationManager.ConnectionStrings["nametoCallBy"].ConnectionString;

If you are using requests module, an alternative option is to write an auth class, as discussed in "New Forms of Authentication":

import requests

class BearerAuth(requests.auth.AuthBase):
    def __init__(self, token):
        self.token = token
    def __call__(self, r):
        r.headers["authorization"] = "Bearer " + self.token
        return r

and then can you send requests like this

response = requests.get('https://www.example.com/', auth=BearerAuth('3pVzwec1Gs1m'))

which allows you to use the same auth argument just like basic auth, and may help you in certain situations.

If you only need to show time value in a datagrid or label similar, best way is convert directly time in datetime datatype.

SELECT CONVERT(datetime,myTimeField) as myTimeField FROM Table1

var bs []byte
value, _ := strconv.ParseInt(string(bs), 10, 64)

Rotation is a composition of a transpose and a flip.

Which in OpenCV can be written like this (Python example below):

img = cv.LoadImage("path_to_image.jpg")
timg = cv.CreateImage((img.height,img.width), img.depth, img.channels) # transposed image

# rotate counter-clockwise
cv.Transpose(img,timg)
cv.Flip(timg,timg,flipMode=0)
cv.SaveImage("rotated_counter_clockwise.jpg", timg)

# rotate clockwise
cv.Transpose(img,timg)
cv.Flip(timg,timg,flipMode=1)
cv.SaveImage("rotated_clockwise.jpg", timg)

You can use Poppy for this. It is normally used to gather the stack trace during a crash but it can also output it for a running program as well.

Now here's the good part: it can output the actual parameter values for each function on the stack, and even local variables, loop counters, etc.

For people who will going to look for 'How to change dynamically content on pseudo element adding new line sign" here's answer

Html chars like 
 will not work appending them to html using JavaScript because those characters are changed on document render

Instead you need to find unicode representation of this characters which are U+000D and U+000A so we can do something like

var el = document.querySelector('div');_x000D_
var string = el.getAttribute('text').replace(/, /, '\u000D\u000A');_x000D_
el.setAttribute('text', string);

div:before{_x000D_
   content: attr(text);_x000D_
   white-space: pre;_x000D_
}

<div text='I want to break it in javascript, after comma sign'></div> 

Hope this save someones time, good luck :)

Have you taken a look at put.py? I've used it in the past. You can also just hack up your own request with urllib.

In the form closest to your original:

import datetime

def UtcNow():
    now = datetime.datetime.utcnow()
    return now

If you need to know the number of seconds from 1970-01-01 rather than a native Python datetime, use this instead:

return (now - datetime.datetime(1970, 1, 1)).total_seconds()

Python has naming conventions that are at odds with what you might be used to in Javascript, see PEP 8. Also, a function that simply returns the result of another function is rather silly; if it's just a matter of making it more accessible, you can create another name for a function by simply assigning it. The first example above could be replaced with:

utc_now = datetime.datetime.utcnow

Validating it is a valid address is one thing.

But if you're trying to validate a given person lives at a given address, your only almost-guarantee would be a test mail to the address, and even that is not certain if the person is organised or knows somebody at that address.

Otherwise people could just specify an arbitrary random address which they know exists and it would mean nothing to you.

The best you can do for immediate results is request the user send a photographed / scanned copy of the head of their bank statement or some other proof-of-recent-residence, because at least then they have to work harder to forget it, and forging said things show up easily with a basic level of image forensic analysis.

The problem is that you're displaying time(), which is a UNIX timestamp based on GMT/UTC. That’s why it doesn’t change. date() on the other hand, formats the time based on that timestamp.

A timestamp is the number of seconds since the Unix Epoch (January 1 1970 00:00:00 GMT).

echo date('Y-m-d H:i:s T', time()) . "<br>\n";
date_default_timezone_set('UTC');
echo date('Y-m-d H:i:s T', time()) . "<br>\n";

For Access, you can use the SQL Select query I present here:

For example you have this table:

CLIENTE|| NOMBRES || MAIL

888 || T800 ARNOLD || [email protected]

123 || JOHN CONNOR || [email protected]

125 || SARAH CONNOR ||[email protected]

And you need to select only distinct mails. You can do it with this:

SQL SELECT:

SELECT MAX(p.CLIENTE) AS ID_CLIENTE
, (SELECT TOP 1 x.NOMBRES 
    FROM Rep_Pre_Ene_MUESTRA AS x 
    WHERE x.MAIL=p.MAIL 
     AND x.CLIENTE=(SELECT MAX(l.CLIENTE) FROM Rep_Pre_Ene_MUESTRA AS l WHERE x.MAIL=l.MAIL)) AS NOMBRE, 
p.MAIL
FROM Rep_Pre_Ene_MUESTRA AS p
GROUP BY p.MAIL;

You can use this to select the maximum ID, the correspondent name to that maximum ID , you can add any other attribute that way. Then at the end you put the distinct column to filter and you only group it with that last distinct column.

This will bring you the maximum ID with the correspondent data, you can use min or any other functions and you replicate that function to the sub-queries.

This select will return:

CLIENTE|| NOMBRES || MAIL

888 || T800 ARNOLD || [email protected]

125 || SARAH CONNOR ||[email protected]

Remember to index the columns you select and the distinct column must have not numeric data all in upper case or in lower case, or else it won't work. This will work with only one registered mail as well. Happy coding!!!

There is an indexOf method that all arrays have (except Internet Explorer 8 and below) that will return the index of an element in the array, or -1 if it's not in the array:

if (yourArray.indexOf("someString") > -1) {
    //In the array!
} else {
    //Not in the array
}

If you need to support old IE browsers, you can polyfill this method using the code in the MDN article.

For my problem, I removed the #include <glui.h> statement and it ran without a problem.

I think you need this ..

Dim n as Integer   

For n = 5 to 17
  msgbox cells(n,3) '--> sched waste
  msgbox cells(n,4) '--> type of treatm
  msgbox format(cells(n,5),"dd/MM/yyyy") '--> Lic exp
  msgbox cells(n,6) '--> email col

F# is not yet-another-programming-language if you are comparing it to C#, C++, VB. C#, C, VB are all imperative or procedural programming languages. F# is a functional programming language.

Two main benefits of functional programming languages (compared to imperative languages) are 1. that they don't have side-effects. This makes mathematical reasoning about properties of your program a lot easier. 2. that functions are first class citizens. You can pass functions as parameters to another functions just as easily as you can other values.

Both imperative and functional programming languages have their uses. Although I have not done any serious work in F# yet, we are currently implementing a scheduling component in one of our products based on C# and are going to do an experiment by coding the same scheduler in F# as well to see if the correctness of the implementation can be validated more easily than with the C# equivalent.

Declare list item components as final outside your setOnClickListener or whatever you want to apply on your list item like this:

final View yourView;
final TextView yourTextView;

And in overriding onClick or whatever method you use, just set colors as needed like this:

yourView.setBackgroundColor(Color.WHITE/*or whatever RGB suites good contrast*/);
yourTextView.setTextColor(Color.BLACK/*or whatever RGB suites good contrast*/);

Or without the final declaration, if let's say you implement an onClick() for a custom adapter to populate a list, this is what I used in getView() for my setOnClickListener/onClick():

//reset color for all list items in case any item was previously selected
for(int i = 0; i < parent.getChildCount(); i++)
{
  parent.getChildAt(i).setBackgroundColor(Color.BLACK);
  TextView text=(TextView) parent.getChildAt(i).findViewById(R.id.item);
  text.setTextColor(Color.rgb(0,178,178));
}
//highlight currently selected item
 parent.getChildAt(position).setBackgroundColor(Color.rgb(0,178,178));
 TextView text=(TextView) parent.getChildAt(position).findViewById(R.id.item);
 text.setTextColor(Color.rgb(0,178,178));

var myDate = new Date(); // Set this to your date in whichever timezone.
var utcDate = myDate.toUTCString();

$('img.conversation_img[alt="example"]')
    .each(function(){
         alert($(this).attr('src'))
    });

This will display src attributes of all images of class 'conversation_img' with alt='example'

It's not that different in bash.

workdone=0
while : ; do
  ...
  if [ "$workdone" -ne 0 ]; then
      break
  fi
done

: is the no-op command; its exit status is always 0, so the loop runs until workdone is given a non-zero value.

There are many ways you could set and test the value of workdone in order to exit the loop; the one I show above should work in any POSIX-compatible shell.

From python wiki:

>>> from operator import itemgetter, attrgetter    
>>> sorted(student_tuples, key=itemgetter(2))
[('dave', 'B', 10), ('jane', 'B', 12), ('john', 'A', 15)]    
>>> sorted(student_objects, key=attrgetter('age'))
[('dave', 'B', 10), ('jane', 'B', 12), ('john', 'A', 15)]

I know that this question has been answered, And all the answers are nice. But I wanted to add my two cents to this question for people who have similar (but not exactly the same) problem.

In a more general way, we can do something like this:

$('body').click(function(evt){    
    if(!$(evt.target).is('#menu_content')) {
        //event handling code
    }
});

This way we can handle not only events fired by anything except element with id menu_content but also events that are fired by anything except any element that we can select using CSS selectors.

For instance in the following code snippet I am getting events fired by any element except all <li> elements which are descendants of div element with id myNavbar.

$('body').click(function(evt){    
    if(!$(evt.target).is('div#myNavbar li')) {
        //event handling code
    }
});

Anyone else stumbling upon this answer should note that jQuery now (>=1.3) has outerHeight/outerWidth functions to retrieve the width including padding/borders, e.g.

$(elem).outerWidth(); // Returns the width + padding + borders

To include the margin as well, simply pass true:

$(elem).outerWidth( true ); // Returns the width + padding + borders + margins

xcode is now available for free from the app store. Just "buy it" (for free) and it will download. To get the command line tools go into preferences/downloads and "install command line compiler tools".

Instead of gcc you are using clang, but it works the same.

In Selenium IDE you can do:

Command   |   clickAndWait
Target    |   //input[@value='Next' and @title='next']

It should work fine.

I ended up using this solution.

decimal weeklyWage;
decimal.TryParse(items[2],NumberStyles.Any, new NumberFormatInfo() { NumberDecimalSeparator = "."}, out weeklyWage);

A major cause of this (which I had recently), is if you have this on for example a flash drive.

You can develop and do everything, but on most systems it stops you from running the .exe file from there, whether it be the debug or release version.

This is not possible with css, but I have used one css trick in one of my website, please check if this works for you.

The trick is: wrap the input box with a div and make it relative, place a transparent image inside the div and make it absolute over the input text box, so that no one can edit it.

css

.txtBox{
    width:250px;
    height:25px;
    position:relative;
}
.txtBox input{
    width:250px;
    height:25px;
}
.txtBox img{
    position:absolute;
    top:0;
    left:0
}

html

<div class="txtBox">
<input name="" type="text" value="Text Box" />
<img src="http://dev.w3.org/2007/mobileok-ref/test/data/ROOT/GraphicsForSpacingTest/1/largeTransparent.gif" width="250" height="25" alt="" />
</div>

You are conflating Optional with having a default. An Optional accepts either a value or nil. Having a default permits the argument to be omitted in calling the function. An argument can have a default value with or without being of Optional type.

func someFunc(param1: String?,
          param2: String = "default value",
          param3: String? = "also has default value") {
    print("param1 = \(param1)")

    print("param2 = \(param2)")

    print("param3 = \(param3)")
}

Example calls with output:

someFunc(param1: nil, param2: "specific value", param3: "also specific value")

param1 = nil
param2 = specific value
param3 = Optional("also specific value")

someFunc(param1: "has a value")

param1 = Optional("has a value")
param2 = default value
param3 = Optional("also has default value")

someFunc(param1: nil, param3: nil)

param1 = nil
param2 = default value
param3 = nil

To summarize:

• Type with ? (e.g. String?) is an Optional may be nil or may contain an instance of Type
• Argument with default value may be omitted from a call to function and the default value will be used
• If both Optional and has default, then it may be omitted from function call OR may be included and can be provided with a nil value (e.g. param1: nil)

This:

doc.LoadXml(HttpContext.Current.Server.MapPath("officeList.xml"));

should be:

doc.Load(HttpContext.Current.Server.MapPath("officeList.xml"));

LoadXml() is for loading an XML string, not a file name.

7 years later and this code has helped me. However, my times still were not showing up correctly.

Using Matplotlib 2.0.0 and I had to add the following bit of code from Editing the date formatting of x-axis tick labels in matplotlib by Paul H.

import matplotlib.dates as mdates
myFmt = mdates.DateFormatter('%d')
ax.xaxis.set_major_formatter(myFmt)

I changed the format to (%H:%M) and the time displayed correctly.

All thanks to the community.

The only valid answer would be the pause command.

Though this does not wait specifically for the 'ENTER' key, it waits for any key that is pressed.

And just in case you want it convenient for the user, pause is the best option.

For those of you who hit this stackoverflow entry because it ranks high for the phrase:

The page cannot be displayed because an internal server error has occurred.

In my personal situation with this exact error message, I had turned on python 2.7 thinking I could use some python with my .NET API. I then had that exact error message when I attempted to deploy a vanilla version of the API or MVC from visual studio pro 2013. I was deploying to an azure cloud webapp.

Hope this helps anyone with my same experience. I didn't even think to turn off python until I found this suggestion.

I think this is what you want:

REGEX_DATE='^\d{2}[/-]\d{2}[/-]\d{4}$'

echo "$1" | grep -P -q $REGEX_DATE
echo $?

I've used the -P switch to get perl regex.

Since a stored procedure is created, altered and dropped using queries you actually CAN manage them using phpMyAdmin.

To create a stored procedure, you can use the following (change as necessary) :

CREATE PROCEDURE sp_test()
BEGIN
  SELECT 'Number of records: ', count(*) from test;
END//

And make sure you set the "Delimiter" field on the SQL tab to //.

Once you created the stored procedure it will appear in the Routines fieldset below your tables (in the Structure tab), and you can easily change/drop it.

To use the stored procedure from PHP you have to execute a CALL query, just like you would do in plain SQL.

Even though your JDK in eclipse is 1.7, you need to make sure eclipse compilance level also set to 1.7. You can check compilance level--> Window-->Preferences--> Java--Compiler--compilance level.

Unsupported major minor error happens in cases where compilance level doesn't match with runtime.

Maven is great. The reason for its reputation has got to do with the steep learning curve, in my opinion. (which I am finally close to getting over)

The documentation is a bit rough to wade through, simply because it feels like there's a lot of text and new things to comprehend before it starts making sense. I say time is all that's needed for Maven to become more widely praised.

My solution that worked was to open R studio options and select global miror (the field was empty before) and the error went away.

It means that using the bodyParser() constructor has been deprecated, as of 2014-06-19.

app.use(bodyParser()); //Now deprecated

You now need to call the methods separately

app.use(bodyParser.urlencoded());

app.use(bodyParser.json());

And so on.

If you're still getting a warning with urlencoded you need to use

app.use(bodyParser.urlencoded({
  extended: true
}));

The extended config object key now needs to be explicitly passed, since it now has no default value.

If you are using Express >= 4.16.0, body parser has been re-added under the methods express.json() and express.urlencoded().

Unfortunately (unless I'm mistaken), I think you need to iterate over the results object.

for(var i = 0; i < results.length; i += 1){
    var result = results[i];
    if(result.id === id){
        return result;
    }
}

At least this way it will break out of the iteration as soon as it finds the correct matching id.
