Make sure you have Data Source and not DataSource in your connection string. The space is important. Trust me. I'm an idiot.

It should work - as long as the data variable is actually an array containing a dictionary with the key SPORT

NSArray *data = [NSArray arrayWithObject:[NSMutableDictionary dictionaryWithObject:@"foo" forKey:@"BAR"]];    
NSArray *filtered = [data filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"(BAR == %@)", @"foo"]];

Filtered in this case contains the dictionary.

(the %@ does not have to be quoted, this is done when NSPredicate creates the object.)

Or, more elegantly: request.path_info

Request Rack Documentation

foreach($_POST as $key=>$value)
{

   if(empty(trim($value))
        echo "$key input required of value ";

}

I got a solution in python, I modified the webdriver class bassed on PersistenBrowser class that I found.

https://github.com/axelPalmerin/personal/commit/fabddb38a39f378aa113b0cb8d33391d5f91dca5

replace the webdriver module /usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py

Ej. to use:

from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

runDriver = sys.argv[1]
sessionId = sys.argv[2]

def setBrowser():
    if eval(runDriver):
        webdriver = w.Remote(command_executor='http://localhost:4444/wd/hub',
                     desired_capabilities=DesiredCapabilities.CHROME,
                     )
    else:
        webdriver = w.Remote(command_executor='http://localhost:4444/wd/hub',
                             desired_capabilities=DesiredCapabilities.CHROME,
                             session_id=sessionId)

    url = webdriver.command_executor._url
    session_id = webdriver.session_id
    print url
    print session_id
    return webdriver

As many above have suggested, a good way is to test them via your public interfaces.

If you do this, it's a good idea to use a code coverage tool (like Emma) to see if your private methods are in fact being executed from your tests.

$('#myForm').submit(function() {
    var c = confirm("Click OK to continue?");
    return c; //you can just return c because it will be true or false
});

My answer is too late, but it can help others.

I had the same problem, even when I used a form tag.

I solved it by declaring Meta Charset in the header of the page:

<meta charset = "UTF-8" />

No you don't need to call the base destructor, a base destructor is always called for you by the derived destructor. Please see my related answer here for order of destruction.

To understand why you want a virtual destructor in the base class, please see the code below:

class B
{
public:
    virtual ~B()
    {
        cout<<"B destructor"<<endl;
    }
};


class D : public B
{
public:
    virtual ~D()
    {
        cout<<"D destructor"<<endl;
    }
};

When you do:

B *pD = new D();
delete pD;

Then if you did not have a virtual destructor in B, only ~B() would be called. But since you have a virtual destructor, first ~D() will be called, then ~B().

std::queue<myclass*> my_queue; will do the job.

See here for more information on this container.

There are two attributes, namely readonly and disabled, that can make a semi-read-only input. But there is a tiny difference between them.

<input type="text" readonly />
<input type="text" disabled />

• The readonly attribute makes your input text disabled, and users are not able to change it anymore.
• Not only will the disabled attribute make your input-text disabled(unchangeable) but also cannot it be submitted.

jQuery approach (1):

$("#inputID").prop("readonly", true);
$("#inputID").prop("disabled", true);

jQuery approach (2):

$("#inputID").attr("readonly","readonly");
$("#inputID").attr("disabled", "disabled");

JavaScript approach:

document.getElementById("inputID").readOnly = true;
document.getElementById("inputID").disabled = true;

PS disabled and readonly are standard html attributes. prop introduced with jQuery 1.6.

so you are inside a for or while loop. Using break; will put you outside of the loop. As in, it will end. Continue; will tell it to run the next iteration.

No point in using continue in if statement, but break; is useful. In switch...case, always use break; to end a case, so it does not executes another case.

I know this is an old post, but I found it and then found someone who suggested Total Mail Converter. I was able to convert my folder with 2k .msg files into .txt. It also allows you to convert into PDF and other popular formats.

It's a great tool that I am glad someone suggested as it will save me several days.

FYI - My project is combining the .msg files into one text file so that I can run a script to extract certain information from the files (ie: email and links). Instead of 2k files, I can work with one.

org.apache.ant has a FileUtils class with a getRelativePath method. Haven't tried it myself yet, but could be worthwhile to check it out.

http://javadoc.haefelinger.it/org.apache.ant/1.7.1/org/apache/tools/ant/util/FileUtils.html#getRelativePath(java.io.File, java.io.File)

Using 'now()' as default value automatically generates time-stamp.

REST doesn't have a recommended date format. Really it boils down to what works best for your end user and your system. Personally, I would want to stick to a standard like you have for ISO 8601 (url encoded).

If not having ugly URI is a concern (e.g. not including the url encoded version of :, -, in you URI) and (human) addressability is not as important, you could also consider epoch time (e.g. http://example.com/start/1331162374). The URL looks a little cleaner, but you certainly lose readability.

The /2012/03/07 is another format you see a lot. You could expand upon that I suppose. If you go this route, just make sure you're either always in GMT time (and make that clear in your documentation) or you might also want to include some sort of timezone indicator.

Ultimately it boils down to what works for your API and your end user. Your API should work for you, not you for it ;-).

Adding style="width:100%;max-width:640px" to the image tag will scale it up to the viewport width, i.e. for larger windows it will look fixed width.

You can use the TelephonyManager to do this:

TelephonyManager t = (TelephonyManager)getSystemService(TELEPHONY_SERVICE); 
String number = t.getLine1Number();

Have you used

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

It's been a while, but last time I had something similar:

ROLLBACK TRAN

or trying to

COMMIT

what had allready been done free'd everything up so I was able to clear things out and start again.

HQL can cause security concerns like SQL injection.

buf.delete(0,  buf.length());

It should be

if (*message == '\0')

In C, simple quotes delimit a single character whereas double quotes are for strings.

Apple recommends for stylistic purposes.If you write this code:

@property (nonatomic,assign) BOOL working;

Then you can not use [object isWorking].
It will show an error. But if you use below code means

@property (assign,getter=isWorking) BOOL working;

So you can use [object isWorking] .

#include <iostream>
#include <iomanip>
using namespace std;

You can enter the line using namespace std; for your convenience. Otherwise, you'll have to explicitly add std:: every time you wish to use cout, fixed, showpoint, setprecision(2) and endl

int main()
{
    double num1 = 3.12345678;
    cout << fixed << showpoint;
    cout << setprecision(2);
    cout << num1 << endl;
return 0;
}

This question was asked before Java 7 release but now, there is another possible way using Java 7 (and above) API:

double random = ThreadLocalRandom.current().nextDouble(min, max);

nextDouble will return a pseudorandom double value between the minimum (inclusive) and the maximum (exclusive). The bounds are not necessarily int, and can be double.

You open the file in text mode.

More specifically:

ifile  = open('sample.csv', "rt", encoding=<theencodingofthefile>)

Good guesses for encoding is "ascii" and "utf8". You can also leave the encoding off, and it will use the system default encoding, which tends to be UTF8, but may be something else.

Swift 3:

private func validate(phoneNumber: String) -> Bool {
    let charcterSet  = NSCharacterSet(charactersIn: "+0123456789").inverted
    let inputString = phoneNumber.components(separatedBy: charcterSet)
    let filtered = inputString.joined(separator: "")
    return  phoneNumber == filtered
}

To make this work on Ubuntu Linux:

1. I installed the Ubuntu package ruby-json:

   apt-get install ruby-json
   

2. I wrote the script in ${HOME}/rubybin/jsonDEMO

3. $HOME/.bashrc included:

   ${HOME}/rubybin:${PATH}
   

(On this occasion I also typed the above on the bash command line.)

Then it worked when I entered on the command line:

jsonDemo

Here is an easy implementation.

#include <Windows.h>
#include <iostream>

using namespace std;


class SingletonClass {

public:
    static SingletonClass* getInstance() {

    return (!m_instanceSingleton) ?
        m_instanceSingleton = new SingletonClass : 
        m_instanceSingleton;
    }

private:
    // private constructor and destructor
    SingletonClass() { cout << "SingletonClass instance created!\n"; }
    ~SingletonClass() {}

    // private copy constructor and assignment operator
    SingletonClass(const SingletonClass&);
    SingletonClass& operator=(const SingletonClass&);

    static SingletonClass *m_instanceSingleton;
};

SingletonClass* SingletonClass::m_instanceSingleton = nullptr;



int main(int argc, const char * argv[]) {

    SingletonClass *singleton;
    singleton = singleton->getInstance();
    cout << singleton << endl;

    // Another object gets the reference of the first object!
    SingletonClass *anotherSingleton;
    anotherSingleton = anotherSingleton->getInstance();
    cout << anotherSingleton << endl;

    Sleep(5000);

    return 0;
}

Only one object created and this object reference is returned each and every time afterwords.

SingletonClass instance created!
00915CB8
00915CB8

Here 00915CB8 is the memory location of singleton Object, same for the duration of the program but (normally!) different each time the program is run.

N.B. This is not a thread safe one.You have to ensure thread safety.

Found these docu on the google docu pages:

• row --- int --- top row of the range
• column --- int--- leftmost column of the range
• optNumRows --- int --- number of rows in the range.
• optNumColumns --- int --- number of columns in the range

In your example, you would get (if you picked the 3rd row) "C3:O3", cause C --> O is 12 columns

edit

Using the example on the docu:

// The code below will get the number of columns for the range C2:G8
// in the active spreadsheet, which happens to be "4"
var count = SpreadsheetApp.getActiveSheet().getRange(2, 3, 6, 4).getNumColumns(); Browser.msgBox(count);

The values between brackets:
2: the starting row = 2
3: the starting col = C
6: the number of rows = 6 so from 2 to 8
4: the number of cols = 4 so from C to G

So you come to the range: C2:G8

Make it Generic Swift 4

struct Matrix<T> {
    let rows: Int, columns: Int
    var grid: [T]
    init(rows: Int, columns: Int,defaultValue: T) {
        self.rows = rows
        self.columns = columns
        grid = Array(repeating: defaultValue, count: rows * columns) as! [T]

            return grid[(row * columns) + column]
        }
        set {
            assert(indexIsValid(row: row, column: column), "Index out of range")
            grid[(row * columns) + column] = newValue
        }

You could try Directory.Exists(path) and Directory.GetFiles(path) - probably less overhead (no objects - just strings etc).

Please try the following code

Uri.fromFile(new File("/sdcard/sample.jpg"))

You may also use:

request.POST.get('section','') # => [39]
request.POST.get('MAINS','') # => [137] 
request.GET.get('section','') # => [39]
request.GET.get('MAINS','') # => [137]

Using this ensures that you don't get an error. If the POST/GET data with any key is not defined then instead of raising an exception the fallback value (second argument of .get() will be used).

To get a list of threads and their full states using the terminal, you can use the command below:

jstack -l <PID>

Which <PID> is the id of process running on your computer. To get the process id of your java process you can simply run the jps command.

Also, you can analyze your thread dump that produced by jstack in TDAs (Thread Dump Analyzer) such fastthread or spotify thread analyzer tool.

Since we're already using JQuery, we can let page designers add custom messages to the markup rather than the code:

<input ... data-msg-required="my message" ...

Or, a more general solution using a single short data-msg attribute on all fields:

<form id="form1">
    <input type="text" id="firstName" name="firstName" 
        data-msg="Please enter your first name" />
    <br />
    <input type="text" id="lastName" name="lastName" 
        data-msg="Please enter your last name" />
    <br />
    <input type="submit" />
</form>

And the code then contains something like this:

function getMsg(selector) {
    return $(selector).attr('data-msg');
}

$('#form1').validate({
    // ...
    messages: {
        firstName: getMsg('#firstName'),
        lastName: getMsg('#lastName')
    }
    // ...
});

Are you working with a @Service too? Because if you are, then you can @Autowired your PersonRepository to the @Service and then in the service just invoke the Name class and use the form that @CuriosMind... proposed:

@Query(select p from Person p where p.forename = :forename and p.surname = :surname)
User findByForenameAndSurname(@Param("surname") String lastname,
                         @Param("forename") String firstname);
}

and when invoking the method from the repository in the service, you can then pass those parameters.

The above answers illustrate the reason for this java.net.SocketException: Broken pipe: the other end closed the connection. I would like to share experience what happened when I encountered it:

1. in a client's request, the Content-Type header is mistakenly set larger than request body actually is (in fact there was no body at all)
2. the bottom service in tomcat socket was waiting for that sized body data (http is on TCP which ensures delivery by encapsulating and ...)
3. when 60 seconds expired, tomcat throws time out exception: Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception java.net.SocketTimeoutException: null
4. client receives a response with status code 500 because of the timeout exception.
5. client close connection (because it receives response).
6. tomcat throws java.net.SocketException: Broken pipe because client closed it.

Sometimes, tomcat does not throw broken pip exception, because timeout exception close the connection, why such a difference is confusing me too.

In Moment.js, the from() method has the daily precision you're looking for:

var today = new Date();
var tomorrow = new Date();
var yesterday = new Date();
tomorrow.setDate(today.getDate()+1);
yesterday.setDate(today.getDate()-1);

moment(today).from(moment(yesterday)); // "in a day"
moment(today).from(moment(tomorrow)); // "a day ago" 

moment(yesterday).from(moment(tomorrow)); // "2 days ago" 
moment(tomorrow).from(moment(yesterday)); // "in 2 days"

I like Andrew's suggestion, and in fact the CSS rule only needs to be:

:checked + label {
   font-weight: bold;
}

I like to rely on implicit association of the label and the input element, so I'd do something like this:

<label>
   <input type="checkbox"/>
   <span>Bah</span>
</label>

with CSS:

:checked + span {
    font-weight: bold;
}

Just a reminder:

Remove orientation from android:configChanges attribute for the activity in your manifest xml file if you defined it:

android:configChanges="orientation|screenLayout|screenSize"

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

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

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

unique random number from 0 to 9

      int sum = 0;
        int[] hue = new int[10];
        for (int i = 0; i < 10; i++)
        {

            int m;
            do
            {
                m = rand.Next(0, 10);
            } while (hue.Contains(m) && sum != 45);
            if (!hue.Contains(m))
            {
                hue[i] = m;
                sum = sum + m;
            }

Most of the answers don't cover cases where there is more than 24h. This one does. I suggest extending Date object:

class SuperDate extends Date {_x000D_
  get raceTime() {_x000D_
    return Math.floor(this/36e5).toString().padStart(2,'0')_x000D_
    + this.toISOString().slice(13, -1)_x000D_
  }_x000D_
}_x000D_
_x000D_
console.log('marathon', new SuperDate(11235200).raceTime)_x000D_
console.log('ironman', new SuperDate(40521100).raceTime)_x000D_
console.log('spartathlon', new SuperDate(116239000).raceTime)_x000D_
console.log('epoch', new SuperDate(new Date()).raceTime)

This approach works great with Firestore Timestamp objects which are similar to what you need:

class SuperDate extends Date {_x000D_
  fromFirestore (timestamp) {_x000D_
    return new SuperDate(timestamp.seconds * 1000 + timestamp.nanoseconds / 1000000)_x000D_
  }_x000D_
  get raceTime() {_x000D_
    return Math.floor(this/36e5).toString().padStart(2,'0')_x000D_
    + this.toISOString().slice(13, -1)_x000D_
  }_x000D_
}_x000D_
_x000D_
const timestamp = {seconds: 11235, nanoseconds: 200000000}_x000D_
_x000D_
console.log('timestamp', new SuperDate().fromFirestore(timestamp))_x000D_
console.log('marathon', new SuperDate().fromFirestore(timestamp).raceTime)

If you are fetching the URL from a database you can manually assign it to the web service proxy class URL property. This should be done before calling the web method.

If you would like to use the config file, you can set the proxy classes URL behavior to dynamic.

This may be OLD, but here is the best answer:

    float dist = (float) Math.sqrt(
            Math.pow(x1 - x2, 2) +
            Math.pow(y1 - y2, 2) );

Why would UPDLOCK block selects? The Lock Compatibility Matrix clearly shows N for the S/U and U/S contention, as in No Conflict.

As for the HOLDLOCK hint the documentation states:

HOLDLOCK: Is equivalent to SERIALIZABLE. For more information, see SERIALIZABLE later in this topic.

...

SERIALIZABLE: ... The scan is performed with the same semantics as a transaction running at the SERIALIZABLE isolation level...

and the Transaction Isolation Level topic explains what SERIALIZABLE means:

No other transactions can modify data that has been read by the current transaction until the current transaction completes.

Other transactions cannot insert new rows with key values that would fall in the range of keys read by any statements in the current transaction until the current transaction completes.

Therefore the behavior you see is perfectly explained by the product documentation:

• UPDLOCK does not block concurrent SELECT nor INSERT, but blocks any UPDATE or DELETE of the rows selected by T1
• HOLDLOCK means SERALIZABLE and therefore allows SELECTS, but blocks UPDATE and DELETES of the rows selected by T1, as well as any INSERT in the range selected by T1 (which is the entire table, therefore any insert).
• (UPDLOCK, HOLDLOCK): your experiment does not show what would block in addition to the case above, namely another transaction with UPDLOCK in T2:
  SELECT * FROM dbo.Test WITH (UPDLOCK) WHERE ...
• TABLOCKX no need for explanations

The real question is what are you trying to achieve? Playing with lock hints w/o an absolute complete 110% understanding of the locking semantics is begging for trouble...

After OP edit:

I would like to select rows from a table and prevent the data in that table from being modified while I am processing it.

The you should use one of the higher transaction isolation levels. REPEATABLE READ will prevent the data you read from being modified. SERIALIZABLE will prevent the data you read from being modified and new data from being inserted. Using transaction isolation levels is the right approach, as opposed to using query hints. Kendra Little has a nice poster exlaining the isolation levels.

If you don't want to duplicate code, and like me you just want to show stats, in your view model, you could just pass in the models you want to get data from like so:

public class GameViewModel
{
    public virtual Ship Ship { get; set; }
    public virtual GamePlayer GamePlayer { get; set; }     
}

Then, in your controller just run your queries on the respective models, pass them to the view model and return it, example:

GameViewModel PlayerStats = new GameViewModel();

GamePlayer currentPlayer = (from c in db.GamePlayer [more queries]).FirstOrDefault();

[code to check if results]

//pass current player into custom view model
PlayerStats.GamePlayer = currentPlayer;

Like I said, you should only really do this if you want to display stats from the relevant tables, and there's no other part of the CRUD process happening, for security reasons other people have mentioned above.

5. Quit the Registry Editor.

A couple of "enhancements" I use for debugging, especially when running projects (ie not in debug mode).

1. Default the message-box title to the name of the calling method. This is handy for stopping a thread at a given point, but must be cleaned-up before release.

2. Automatically copy the caller-name and message to the clipboard, because you can't search an image!

   package forumposts;
   
   import java.awt.Toolkit;
   import java.awt.datatransfer.Clipboard;
   import java.awt.datatransfer.StringSelection;

       }

           error(message, theNameOfTheMethodThatCalledMe());
       }
       public static void error(String message, String caller) {

       }
   
       public static void show(String message, String title, int iconId) {
           setClipboard(title+":"+NEW_LINE+message);
           JOptionPane.showMessageDialog(null, message, title, iconId);
       }
       private static final String NEW_LINE = System.lineSeparator();
   
       public static String theNameOfTheMethodThatCalledMe() {
           return Thread.currentThread().getStackTrace()[3].getMethodName();
       }
   
       public static void setClipboard(String message) {
           CLIPBOARD.setContents(new StringSelection(message), null);
           // nb: we don't respond to the "your content was splattered"
           //     event, so it's OK to pass a null owner.
       }
       private static final Toolkit AWT_TOOLKIT = Toolkit.getDefaultToolkit();
       private static final Clipboard CLIPBOARD = AWT_TOOLKIT.getSystemClipboard();
   
   }
   

The full class also has debug and warning methods, but I cut them for brevity and you get the main points anyway. You can use a public static boolean isDebugEnabled to suppress debug messages. If done properly the optimizer will (almost) remove these method calls from your production code. See: http://c2.com/cgi/wiki?ConditionalCompilationInJava

Cheers. Keith.

You can also use the xattr command as in Stack Overflow question How do I remove the "extended attributes" on a file in Mac OS X?.

Just remove the com.apple.quarantine attribute. It works even if you don't have an administrator account, which can be a plus. After that, the app isn't considered "downloaded" and is therefore not blocked.

The proper data type for "2010-12-20 00:00:00.0000000" value is DATETIME2(7) / DT_DBTIME2 ().

But used data type for CYCLE_DATE field is DATETIME - DT_DATE. This means milliseconds precision with accuracy down to every third millisecond (yyyy-mm-ddThh:mi:ss.mmL where L can be 0,3 or 7).

The solution is to change CYCLE_DATE date type to DATETIME2 - DT_DBTIME2.

It resolved my problem, this is 1.7.

C is the core language that most closely resembles and directly translates into CPU machine code. CPUs follow instructions that move, add, logically combine, compare, jump, push and pop. C does exactly this using much easier syntax. If you study the disassembly, you can learn to write C code that is just as fast and compact as assembly. It is my preferred language on 8 bit micro controllers with limited memory. If you write a large PC program in C you will get into trouble because of its limited organization. That is where object oriented programming becomes powerful. The ability of C++ and C# classes to contain data and functions together enforces organization which in turn allows more complex operability over C. C++ was essential for quick processing in the past when CPUs only had one core. I am beginning to learn C# now. Its class only structure appears to enforce a higher degree of organization than C++ which should ultimately lead to faster development and promote code sharing. C# is not interpreted like VB. It is partially compiled at development time and then further translated at run time to become more platform friendly.

Just in case of someone has the same problem. I'am using vim with YouCompleteMe, failed to start ycmd with this error message, what I did is: export LC_CTYPE="en_US.UTF-8", the problem is gone.

Horizontal scrollbars in a HTML Select are not natively supported. However, here's a way to create the appearance of a horizontal scrollbar:

1. First create a css class

<style type="text/css">
 .scrollable{
   overflow: auto;
   width: 70px; /* adjust this width depending to amount of text to display */
   height: 80px; /* adjust height depending on number of options to display */
   border: 1px silver solid;
 }
 .scrollable select{
   border: none;
 }
</style>

2. Wrap the SELECT inside a DIV - also, explicitly set the size to the number of options.

<div class="scrollable">
<select size="6" multiple="multiple">
    <option value="1" selected>option 1 The Long Option</option>
    <option value="2">option 2</option>
    <option value="3">option 3</option>
    <option value="4">option 4</option>
    <option value="5">option 5 Another Longer than the Long Option ;)</option>
    <option value="6">option 6</option>
</select>
</div>

Don't forget to take into consideration the global flag in your regexp :

var reg = /abc/g;
!!'abcdefghi'.match(reg); // => true
!!'abcdefghi'.match(reg); // => true
reg.test('abcdefghi');    // => true
reg.test('abcdefghi');    // => false <=

This is because Regexp keeps track of the lastIndex when a new match is found.

Java 8: Use random generator isolated to the current thread: ThreadLocalRandom nextBoolean()

Like the global Random generator used by the Math class, a ThreadLocalRandom is initialized with an internally generated seed that may not otherwise be modified. When applicable, use of ThreadLocalRandom rather than shared Random objects in concurrent programs will typically encounter much less overhead and contention.

java.util.concurrent.ThreadLocalRandom.current().nextBoolean();

"2011-05-19 10:30:14".to_time

You could also do this which would include all JARs in the local repository. This way you wouldn't have to specify it every time.

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
}

For me, this was the easiest solution: I added the font-size:62.5%; to the first .ui-datepicker tag in the jquery custom css file:

before:

.ui-datepicker { width: 17em; padding: .2em .2em 0; display: none;} 

after:

.ui-datepicker { width: 17em; padding: .2em .2em 0; display: none; font-size:62.5%; }

I am just beginning to dig deeper into git, so not sure if I understand correctly, but I think the correct answer to the OP's question is that you can run git log --all with a format specification like this: git log --all --pretty=format:'%h: %s %d'. This marks the current checked out version as (HEAD) and you can just grab the next one from the list.

BTW, add an alias like this to your .gitconfig with a slightly better format and you can run git hist --all:

  hist = log --pretty=format:\"%h %ai | %s%d [%an]\" --graph

Regarding the relative versions, I found this post, but it only talks about older versions, there is probably nothing to refer to the newer versions.

you can use Session.Remove() method; Session.Remove

Session.Remove("yourSessionName");

If you can't use rgba due to browser support, and you don't want to include a semi-transparent white PNG, you will have to create two positioned elements. One for the white box, with opacity, and one for the overlaid text, solid.

body { background: red; }_x000D_
_x000D_
.box { position: relative; z-index: 1; }_x000D_
.box .back {_x000D_
    position: absolute; z-index: 1;_x000D_
    top: 0; left: 0; width: 100%; height: 100%;_x000D_
    background: white; opacity: 0.75;_x000D_
}_x000D_
.box .text { position: relative; z-index: 2; }_x000D_
_x000D_
body.browser-ie8 .box .back { filter: alpha(opacity=75); }

<!--[if lt IE 9]><body class="browser-ie8"><![endif]-->_x000D_
<!--[if gte IE 9]><!--><body><!--<![endif]-->_x000D_
    <div class="box">_x000D_
        <div class="back"></div>_x000D_
        <div class="text">_x000D_
            Lorem ipsum dolor sit amet blah blah boogley woogley oo._x000D_
        </div>_x000D_
    </div>_x000D_
</body>

I came up with your case. This is how I sort it out

1. Install Anaconda
2. Create a virtual environment - conda create -n tensor flow
3. Go inside your virtual environment - Source activate tensorflow
4. Inside that install tensorflow. You can install it using pip
5. Finish install

So then the next thing, when you launch it:

6. If you are not inside the virtual environment type - Source Activate Tensorflow
7. Then inside this again install your Jupiter notebook and Pandas libraries, because there can be some missing in this virtual environment

Inside the virtual environment just type:

8. pip install jupyter notebook
9. pip install pandas

Then you can launch jupyter notebook saying:

10. jupyter notebook
11. Select the correct terminal python 3 or 2
12. Then import those modules

Two ways that work:

1. Use stringBuilderObj.setLength(0).
2. Allocate a new one with new StringBuilder() instead of clearing the buffer.

You can use the standard evaluation version of mutate_each (which is mutate_each_) to change the column classes:

dat %>% mutate_each_(funs(factor), l1) %>% mutate_each_(funs(as.numeric), l2)

You can use the zoom property. Check this jsfiddle

For a Table:

SELECT 
  TABLE_NAME,COLUMN_NAME,CONSTRAINT_NAME, REFERENCED_TABLE_NAME,REFERENCED_COLUMN_NAME
FROM
  INFORMATION_SCHEMA.KEY_COLUMN_USAGE
WHERE
  REFERENCED_TABLE_SCHEMA = '<database>' AND
  REFERENCED_TABLE_NAME = '<table>';

For a Column:

SELECT 
  TABLE_NAME,COLUMN_NAME,CONSTRAINT_NAME, REFERENCED_TABLE_NAME,REFERENCED_COLUMN_NAME
FROM
  INFORMATION_SCHEMA.KEY_COLUMN_USAGE
WHERE
  REFERENCED_TABLE_SCHEMA = '<database>' AND
  REFERENCED_TABLE_NAME = '<table>' AND
  REFERENCED_COLUMN_NAME = '<column>';

Basically, we changed REFERENCED_TABLE_NAME with REFERENCED_COLUMN_NAME in the where clause.

You need to set ulimit -c. If you have 0 for this parameter a coredump file is not created. So do this: ulimit -c unlimited and check if everything is correct ulimit -a. The coredump file is created when an application has done for example something inappropriate. The name of the file on my system is core.<process-pid-here>.

I suspect the path is not correct. As mentioned by user7412219 ubuntu and windows deal with path differently. Try to put the image in the same folder as your Notebook and use:

![alt text](Isolated.png "Title")

On windows the desktop should be at: C:\Users\jzhang\Desktop

There are plenty of solutions but none covers why the original statement doesn't work.

CASE last_name WHEN null THEN '' ELSE ' '+last_name

After the when, there is a check for equality, which should be true or false.

If one or both parts of a comparison is null, the result of the comparison will be UNKNOWN, which is treated like false in a case structure. See: https://www.xaprb.com/blog/2006/05/18/why-null-never-compares-false-to-anything-in-sql/

To avoid this, Coalesce is the best way.

You are using the JavaScript array.find() method. Note that this is standard JS, and has nothing to do with jQuery. In fact, your entire code in the question makes no use of jQuery at all.

You can find the documentation for array.find() here: https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Array/find

If you scroll to the bottom of this page, you will note that it has browser support info, and you will see that it states that IE does not support this method.

Ironically, your best way around this would be to use jQuery, which does have similar functionality that is supported in all browsers.

The opposite of the == compare operator is !=.

Optimistic Locking is a strategy where you read a record, take note of a version number (other methods to do this involve dates, timestamps or checksums/hashes) and check that the version hasn't changed before you write the record back. When you write the record back you filter the update on the version to make sure it's atomic. (i.e. hasn't been updated between when you check the version and write the record to the disk) and update the version in one hit.

If the record is dirty (i.e. different version to yours) you abort the transaction and the user can re-start it.

This strategy is most applicable to high-volume systems and three-tier architectures where you do not necessarily maintain a connection to the database for your session. In this situation the client cannot actually maintain database locks as the connections are taken from a pool and you may not be using the same connection from one access to the next.

Pessimistic Locking is when you lock the record for your exclusive use until you have finished with it. It has much better integrity than optimistic locking but requires you to be careful with your application design to avoid Deadlocks. To use pessimistic locking you need either a direct connection to the database (as would typically be the case in a two tier client server application) or an externally available transaction ID that can be used independently of the connection.

In the latter case you open the transaction with the TxID and then reconnect using that ID. The DBMS maintains the locks and allows you to pick the session back up through the TxID. This is how distributed transactions using two-phase commit protocols (such as XA or COM+ Transactions) work.

Also you can use f-string formatting to write integer to file

For appending use following code, for writing once replace 'a' with 'w'.

for i in s_list:
    with open('path_to_file','a') as file:
        file.write(f'{i}\n')

file.close()

try this out let me know what happens.

Form:

<form action="form.php" method="post"> 
Search: <input type="text" name="term" /><br /> 
<input type="submit" value="Submit" /> 
</form> 

Form.php:

$term = mysql_real_escape_string($_REQUEST['term']);    

$sql = "SELECT * FROM liam WHERE Description LIKE '%".$term."%'";
$r_query = mysql_query($sql);

while ($row = mysql_fetch_array($r_query)){ 
echo 'Primary key: ' .$row['PRIMARYKEY']; 
echo '<br /> Code: ' .$row['Code']; 
echo '<br /> Description: '.$row['Description']; 
echo '<br /> Category: '.$row['Category']; 
echo '<br /> Cut Size: '.$row['CutSize'];  
} 

Edit: Cleaned it up a little more.

Final Cut (my test file):

<?php
$db_hostname = 'localhost';
$db_username = 'demo';
$db_password = 'demo';
$db_database = 'demo';

// Database Connection String
$con = mysql_connect($db_hostname,$db_username,$db_password);
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db($db_database, $con);
?>

Use a memory stream

using(MemoryStream ms = new MemoryStream())
{
    image.Save(ms, ...);
    return ms.ToArray();
}

Method #1. Here is the simple function to test if the string contains HTML data:

function isHTML(str) {
  var a = document.createElement('div');
  a.innerHTML = str;

  for (var c = a.childNodes, i = c.length; i--; ) {
    if (c[i].nodeType == 1) return true; 
  }

  return false;
}

The idea is to allow browser DOM parser to decide if provided string looks like an HTML or not. As you can see it simply checks for ELEMENT_NODE (nodeType of 1).

I made a couple of tests and looks like it works:

isHTML('<a>this is a string</a>') // true
isHTML('this is a string')        // false
isHTML('this is a <b>string</b>') // true

This solution will properly detect HTML string, however it has side effect that img/vide/etc. tags will start downloading resource once parsed in innerHTML.

Method #2. Another method uses DOMParser and doesn't have loading resources side effects:

function isHTML(str) {
  var doc = new DOMParser().parseFromString(str, "text/html");
  return Array.from(doc.body.childNodes).some(node => node.nodeType === 1);
}

<sub>Notes:
1. Array.from is ES2015 method, can be replaced with [].slice.call(doc.body.childNodes).
2. Arrow function in some call can be replaced with usual anonymous function.</sub>

You can use it like this, I hope you wont get outdated message now.

  <td valign="top" style="white-space:nowrap" width="237">

As pointed by @ThiefMaster it is recommended to put width and valign to CSS (note: CSS calls it vertical-align).

1)

<td style="white-space:nowrap; width:237px; vertical-align:top;">

2) We can make a CSS class like this, it is more elegant way

In style section

.td-some-name
{
  white-space:nowrap;
  width:237px;
  vertical-align:top;
}

In HTML section

<td class="td-some-name">

You want to git rebase -i to perform an interactive rebase.

If you're currently on your "commit 1", and the commit you want to merge, "commit 2", is the previous commit, you can run git rebase -i HEAD~2, which will spawn an editor listing all the commits the rebase will traverse. You should see two lines starting with "pick". To proceed with squashing, change the first word of the second line from "pick" to "squash". Then save your file, and quit. Git will squash your first commit into your second last commit.

Note that this process rewrites the history of your branch. If you are pushing your code somewhere, you'll have to git push -f and anybody sharing your code will have to jump through some hoops to pull your changes.

Note that if the two commits in question aren't the last two commits on the branch, the process will be slightly different.

@Entity(name = "someThing") => this name will be used to identify the domain ..this name will only be identified by hql queries ..ie ..name of the domain object

@Table(name = "someThing") => this name will be used to which table referred by domain object..ie ..name of the table

I use this code to post HttpRequests.

/// <summary>
        /// Post this message.
        /// </summary>
        /// <param name="url">URL of the document.</param>
        /// <param name="bytes">The bytes.</param>
        public T Post<T>(string url, byte[] bytes)
    {
        T item;
        var request = WritePost(url, bytes);

        using (var response = request.GetResponse() as HttpWebResponse)
        {
            item = DeserializeResponse<T>(response);
            response.Close();
        }

        return item;
    }

    /// <summary>
    /// Writes the post.
    /// </summary>
    /// <param name="url">The URL.</param>
    /// <param name="bytes">The bytes.</param>
    /// <returns></returns>
    private static HttpWebRequest WritePost(string url, byte[] bytes)
    {
        ServicePointManager.ServerCertificateValidationCallback = (sender, certificate, chain, errors) => true;

        HttpWebRequest request = (HttpWebRequest) WebRequest.Create(url);
        Stream stream = null;
        try
        {
            request.Headers.Clear();
            request.PreAuthenticate = true;
            request.Connection = null;
            request.Expect = null;
            request.KeepAlive = false;
            request.ContentLength = bytes.Length;
            request.Timeout = -1;
            request.Method = "POST";
            stream = request.GetRequestStream();
            stream.Write(bytes, 0, bytes.Length);
        }
        catch (Exception e)
        {
            GetErrorResponse(url, e);
        }
        finally
        {
            if (stream != null)
            {
                stream.Flush();
                stream.Close();
            }
        }
        return request;
    }

In regards to your code, try it without the content.Type (request.ContentType = "application/x-www-form-urlencoded";)

update

I believe the problem lies with how you are trying to retrieve the value. When you do a POST and send bytes via the Stream, they will not be passed into the action as a parameter. You'll need to retrieve the bytes via the stream on the server.

On the server, try getting the bytes from stream. The following code is what I use.

     /// <summary> Gets the body. </summary>
     /// <returns> The body. </returns>
     protected byte[] GetBytes()
     {
       byte[] bytes;
        using (var binaryReader = new BinaryReader(Request.InputStream))
        {
            bytes = binaryReader.ReadBytes(Request.ContentLength);
        }

         return bytes;
     }

The first time around, you allocate memory for Vector, which means the variables x,n.

However x doesn't yet point to anything useful.

So that is why second allocation is needed as well.

Instance variable is the variable declared inside a class, but outside a method: something like:

class IronMan {

    /** These are all instance variables **/
    public String realName;
    public String[] superPowers;
    public int age;

    /** Getters and setters here **/
}

Now this IronMan Class can be instantiated in another class to use these variables. Something like:

class Avengers {

    public static void main(String[] a) {
        IronMan ironman = new IronMan();
        ironman.realName = "Tony Stark";
        // or
        ironman.setAge(30);
    }

}

This is how we use the instance variables. Shameless plug: This example was pulled from this free e-book here here.

You can use AppendAllText instead:

File.AppendAllText(filePath, csv);

As the documentation of WriteAllText says:

If the target file already exists, it is overwritten

Also, note that your current code is not using proper new lines, for example in Notepad you'll see it all as one long line. Change the code to this to have proper new lines:

string csv = string.Format("{0},{1}{2}", first, image, Environment.NewLine);

You need to set the text to something other than an empty string. In addition, the .html() function should do it while preserving the HTML structure of the div.

$('#one').html($('#one').html().replace('text','replace'));

Use ClassLoader#getResource() instead if its URI represents a valid local disk file system path.

URL resource = classLoader.getResource("resource.ext");
File file = new File(resource.toURI());
FileInputStream input = new FileInputStream(file);
// ...

If it doesn't (e.g. JAR), then your best bet is to copy it into a temporary file.

Path temp = Files.createTempFile("resource-", ".ext");
Files.copy(classLoader.getResourceAsStream("resource.ext"), temp, StandardCopyOption.REPLACE_EXISTING);
FileInputStream input = new FileInputStream(temp.toFile());
// ...

That said, I really don't see any benefit of doing so, or it must be required by a poor helper class/method which requires FileInputStream instead of InputStream. If you can, just fix the API to ask for an InputStream instead. If it's a 3rd party one, by all means report it as a bug. I'd in this specific case also put question marks around the remainder of that API.

I recently had this problem myself, and once I determined which AppPool was causing the problem, the only way to resolve the issue was remove that app pool completly and create a new one for the site to use.

OSX users can follow by Nicolay77 or mikkom that uses the mdbtools utility. You can install it via Homebrew. Just have your homebrew installed and then go

$ homebrew install mdbtools

Then create one of the scripts described by the guys and use it. I've used mikkom's one, converted all my mdb files into sql.

$ ./to_mysql.sh myfile.mdb > myfile.sql

(which btw contains more than 1 table)

I am not sure if I see this option here. You can just create a /folder in your repository and use it directly:

[a relative link](/folder/myrelativefile.md)

No blob or tree or repository name is needed, and it works like a charm.

Despite the fact that this is a very old question and probably many of the beforementioned ideas solved many problems, I still want to share the solution with the community that fixed my problem.

I found that the problem was a function called "hasItem" which I was using to check whether or not a JSON-Array contains a specific item. In my case I checked for a value of type Long.

And this led to the problem.

Somehow, the Matchers have problems with values of type Long. (I do not use JUnit or Rest-Assured so much so idk. exactly why, but I guess that the returned JSON-data does just contain Integers.)

So what I did to actually fix the problem was the following. Instead of using:

long ID = ...;

...
.then().assertThat()
  .body("myArray", hasItem(ID));

you just have to cast to Integer. So the working code looked like this:

long ID = ...;

...
.then().assertThat()
  .body("myArray", hasItem((int) ID));

That's probably not the best solution, but I just wanted to mention that the exception can also be thrown because of wrong/unknown data types.

The <scope> element can take 6 values: compile, provided, runtime, test, system and import.

This scope is used to limit the transitivity of a dependency, and also to affect the classpath used for various build tasks.

compile

This is the default scope, used if none is specified. Compile dependencies are available in all classpaths of a project. Furthermore, those dependencies are propagated to dependent projects.

provided

This is much like compile, but indicates you expect the JDK or a container to provide the dependency at runtime. For example, when building a web application for the Java Enterprise Edition, you would set the dependency on the Servlet API and related Java EE APIs to scope provided because the web container provides those classes. This scope is only available on the compilation and test classpath, and is not transitive.

runtime

This scope indicates that the dependency is not required for compilation, but is for execution. It is in the runtime and test classpaths, but not the compile classpath.

test

This scope indicates that the dependency is not required for normal use of the application, and is only available for the test compilation and execution phases.

system

This scope is similar to provided except that you have to provide the JAR which contains it explicitly. The artifact is always available and is not looked up in a repository.

import (only available in Maven 2.0.9 or later)

This scope is only used on a dependency of type pom in the section. It indicates that the specified POM should be replaced with the dependencies in that POM's section. Since they are replaced, dependencies with a scope of import do not actually participate in limiting the transitivity of a dependency.

To answer the second part of your question:

How can we use it for running test?

Note that the test scope allows to use dependencies only for the test phase.

Read the documentation for full details.

If you use an = statement to assign a value to a var with an object on the right side, javascript will not copy but reference the object.

You can use lodash's clone method

var obj = {a: 25, b: 50, c: 75};
var A = _.clone(obj);

Or lodash's cloneDeep method if your object has multiple object levels

var obj = {a: 25, b: {a: 1, b: 2}, c: 75};
var A = _.cloneDeep(obj);

Or lodash's merge method if you mean to extend the source object

var obj = {a: 25, b: {a: 1, b: 2}, c: 75};
var A = _.merge({}, obj, {newkey: "newvalue"});

Or you can use jQuerys extend method:

var obj = {a: 25, b: 50, c: 75};
var A = $.extend(true,{},obj);

Here is jQuery 1.11 extend method's source code :

jQuery.extend = jQuery.fn.extend = function() {
    var src, copyIsArray, copy, name, options, clone,
        target = arguments[0] || {},
        i = 1,
        length = arguments.length,
        deep = false;

    // Handle a deep copy situation
    if ( typeof target === "boolean" ) {
        deep = target;

        // skip the boolean and the target
        target = arguments[ i ] || {};
        i++;
    }

    // Handle case when target is a string or something (possible in deep copy)
    if ( typeof target !== "object" && !jQuery.isFunction(target) ) {
        target = {};
    }

    // extend jQuery itself if only one argument is passed
    if ( i === length ) {
        target = this;
        i--;

                if ( target === copy ) {
                    continue;
                }

                // Recurse if we're merging plain objects or arrays
                if ( deep && copy && ( jQuery.isPlainObject(copy) || (copyIsArray = jQuery.isArray(copy)) ) ) {
                    if ( copyIsArray ) {
                        copyIsArray = false;
                        clone = src && jQuery.isArray(src) ? src : [];

                    } else {
                        clone = src && jQuery.isPlainObject(src) ? src : {};
                    }

                    // Never move original objects, clone them
                    target[ name ] = jQuery.extend( deep, clone, copy );

                // Don't bring in undefined values
                } else if ( copy !== undefined ) {
                    target[ name ] = copy;
                }
            }
        }
    }

    // Return the modified object
    return target;
};

Apart from read the big file line by line, you also can read it chunk by chunk. For more refer to this article

var offset = 0;
var chunkSize = 2048;
var chunkBuffer = new Buffer(chunkSize);
var fp = fs.openSync('filepath', 'r');
var bytesRead = 0;
while(bytesRead = fs.readSync(fp, chunkBuffer, 0, chunkSize, offset)) {
    offset += bytesRead;
    var str = chunkBuffer.slice(0, bytesRead).toString();
    var arr = str.split('\n');

    if(bytesRead = chunkSize) {
        // the last item of the arr may be not a full line, leave it to the next chunk
        offset -= arr.pop().length;
    }
    lines.push(arr);
}
console.log(lines);

There is a shell option cdable_vars:

cdable_vars
If this is set, an argument to the cd builtin command that is not a directory is assumed to be the name of a variable whose value is the directory to change to.

You could add this to your .bashrc:

shopt -s cdable_vars
export myFold=$HOME/Files/Scripts/Main

Notice that I've replaced the tilde with $HOME; quotes prevent tilde expansion and Bash would complain that there is no directory ~/Files/Scripts/Main.

Now you can use this as follows:

cd myFold

No $ required. That's the whole point, actually – as shown in other answers, cd "$myFold" works without the shell option. cd myFold also works if the path in myFold contains spaces, no quoting required.

This usually even works with tab autocompletion as the _cd function in bash_completion checks if cdable_vars is set – but not every implementation does it in the same manner, so you might have to source bash_completion again in your .bashrc (or edit /etc/profile to set the shell option).

Other shells have similar options, for example Zsh (cdablevars).

This just means that the git clone copied the files down from github and placed them into a folder. If you try to do it again it will not let you because it can't clone into a folder that has files into it. So if you think the git clone did not complete properly, just delete the folder and do the git clone again. The clone creates a folder the same name as the git repo.

Since I was not too happy with the output of other (non-tree) answers (see my comment at Hassou's answer), I tried to mimic trees output a bit more.

It's similar to the answer of Robert but the horizontal lines do not all start at the beginning, but where there are supposed to start. Had to use perl though, but in my case, on the system where I don't have tree, perl is available.

ls -aR | grep ":$" | perl -pe 's/:$//;s/[^-][^\/]*\//    /g;s/^    (\S)/+-- \1/;s/(^    |    (?= ))/¦   /g;s/    (\S)/+-- \1/'

Output (shortened):

.
+-- fd
+-- net
¦   +-- dev_snmp6
¦   +-- nfsfs
¦   +-- rpc
¦   ¦   +-- auth.unix.ip
¦   +-- stat
¦   +-- vlan
+-- ns
+-- task
¦   +-- 1310
¦   ¦   +-- net
¦   ¦   ¦   +-- dev_snmp6
¦   ¦   ¦   +-- rpc
¦   ¦   ¦   ¦   +-- auth.unix.gid
¦   ¦   ¦   ¦   +-- auth.unix.ip
¦   ¦   ¦   +-- stat
¦   ¦   ¦   +-- vlan
¦   ¦   +-- ns

Suggestions to avoid the superfluous vertical lines are welcome :-)

I still like Ben's solution in the comment of Hassou's answer very much, without the (not perfectly correct) lines it's much cleaner. For my use case I additionally removed the global indentation and added the option to also ls hidden files, like so:

ls -aR | grep ":$" | sed -e 's/:$//' -e 's/[^-][^\/]*\//  /g'

Output (shortened even more):

.
  fd
  net
    dev_snmp6
    nfsfs
    rpc
      auth.unix.ip
    stat
    vlan
  ns

just to add a detail to what Tamlyn wrote, instead of
$('form').get(0).setAttribute('action', 'baz'); //this works

$('form')[0].setAttribute('action', 'baz');
works equally well

Npm and Bower are both dependency management tools. But the main difference between both is npm is used for installing Node js modules but bower js is used for managing front end components like html, css, js etc.

A fact that makes this more confusing is that npm provides some packages which can be used in front-end development as well, like grunt and jshint.

These lines add more meaning

Bower, unlike npm, can have multiple files (e.g. .js, .css, .html, .png, .ttf) which are considered the main file(s). Bower semantically considers these main files, when packaged together, a component.

Edit: Grunt is quite different from Npm and Bower. Grunt is a javascript task runner tool. You can do a lot of things using grunt which you had to do manually otherwise. Highlighting some of the uses of Grunt:

1. Zipping some files (e.g. zipup plugin)
2. Linting on js files (jshint)
3. Compiling less files (grunt-contrib-less)

There are grunt plugins for sass compilation, uglifying your javascript, copy files/folders, minifying javascript etc.

Please Note that grunt plugin is also an npm package.

Question-1

When I want to add a package (and check in the dependency into git), where does it belong - into package.json or into bower.json

It really depends where does this package belong to. If it is a node module(like grunt,request) then it will go in package.json otherwise into bower json.

Question-2

When should I ever install packages explicitly like that without adding them to the file that manages dependencies

It does not matter whether you are installing packages explicitly or mentioning the dependency in .json file. Suppose you are in the middle of working on a node project and you need another project, say request, then you have two options:

• Edit the package.json file and add a dependency on 'request'
• npm install

OR

• Use commandline: npm install --save request

--save options adds the dependency to package.json file as well. If you don't specify --save option, it will only download the package but the json file will be unaffected.

You can do this either way, there will not be a substantial difference.

const list = [
  { qty: 10, size: 'XXL' },
  { qty: 2, size: 'XL' },
  { qty: 8, size: 'M' }
]

list.sort((a, b) => (a.qty > b.qty) ? 1 : -1)

console.log(list)

Out Put :

[
  {
    "qty": 2,
    "size": "XL"
  },
  {
    "qty": 8,
    "size": "M"
  },
  {
    "qty": 10,
    "size": "XXL"
  }
]

Jul 2019 - Dedicated hook/function

A dedicated hook/function can hide implementation details, and provides a simple API to your components.

React 16.8 + Functional Component

const useScroll = () => {
  const elRef = useRef(null);
  const executeScroll = () => elRef.current.scrollIntoView();

  return [executeScroll, elRef];
};

Use it in any functional component.

const ScrollDemo = () => {
    const [executeScroll, elRef] = useScroll()
    useEffect(executeScroll, []) // Runs after component mounts
    
    return <div ref={elRef}>Element to scroll to</div> 
}

full demo

React 16.3 + class Component

const utilizeScroll = () => {
  const elRef = React.createRef();
  const executeScroll = () => elRef.current.scrollIntoView();

  return { executeScroll, elRef };
};

Use it in any class component.

class ScrollDemo extends Component {
  constructor(props) {
    super(props);
    this.elScroll = utilizeScroll();
  }

  componentDidMount() {
    this.elScroll.executeScroll();
  }

  render(){
    return <div ref={this.elScroll.elRef}>Element to scroll to</div> 
  }
}

Long answer: it is possible!

1. Temporarily rename existing xampp folder
2. Install xampp 1.7.7 into xampp folder name
3. Folder containing just installed 1.7.7 distribution rename to different name and previously existing xampp folder rename back just to xampp.
4. In xampp folder rename php and apache folders to different names (I propose php_prev and apache_prev) so you can after switch back to them by renaming them back.
5. Copy apache and php folders from folder with xampp 1.7.7 into xampp directory

6. In xampp directory comment line apache/conf/httpd.conf:458

   #Include "conf/extra/httpd-perl.conf"

7. In xampp directory do next replaces in files:

php/pci.bat:15

from

"C:\xampp\php\.\php.exe" -f "\xampp\php\pci" -- %*

to

set XAMPPPHPDIR=C:\xampp\php "%XAMPPPHPDIR%\php.exe" -f "%XAMPPPHPDIR%\pci" -- %*

php/pciconf.bat:15

from

"C:\xampp\php\.\php.exe" -f "\xampp\php\pciconf" -- %*

to

set XAMPPPHPDIR=C:\xampp\php "%XAMPPPHPDIR%\.\php.exe" -f "%XAMPPPHPDIR%\pciconf" -- %*

php/pear.bat:33

from

IF "%PHP_PEAR_PHP_BIN%"=="" SET "PHP_PEAR_PHP_BIN=C:\xampp\php\.\php.exe"

to

IF "%PHP_PEAR_PHP_BIN%"=="" SET "PHP_PEAR_PHP_BIN=C:\xampp\php\php.exe"

php/peardev.bat:33

from

IF "%PHP_PEAR_PHP_BIN%"=="" SET "PHP_PEAR_PHP_BIN=C:\xampp\php\.\php.exe"

to

IF "%PHP_PEAR_PHP_BIN%"=="" SET "PHP_PEAR_PHP_BIN=C:\xampp\php\php.exe"

php/pecl.bat:32

from

IF "%PHP_PEAR_BIN_DIR%"=="" SET "PHP_PEAR_BIN_DIR=C:\xampp\php" IF "%PHP_PEAR_PHP_BIN%"=="" SET "PHP_PEAR_PHP_BIN=C:\xampp\php\.\php.exe"

to

IF "%PHP_PEAR_BIN_DIR%"=="" SET "PHP_PEAR_BIN_DIR=C:\xampp\php\" IF "%PHP_PEAR_PHP_BIN%"=="" SET "PHP_PEAR_PHP_BIN=C:\xampp\php\php.exe"

php/phar.phar.bat:1

Enjoy new XAMPP with PHP 5.3

Checked by myself in XAMPP 5.6.31, 7.0.15 & 7.1.1 with XAMPP Control Panel v3.2.2

using from ListSelectionModel:

ListSelectionModel cellSelectionModel = table.getSelectionModel();
cellSelectionModel.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);

cellSelectionModel.addListSelectionListener(new ListSelectionListener() {
  public void valueChanged(ListSelectionEvent e) {
    String selectedData = null;

    int[] selectedRow = table.getSelectedRows();
    int[] selectedColumns = table.getSelectedColumns();

    for (int i = 0; i < selectedRow.length; i++) {
      for (int j = 0; j < selectedColumns.length; j++) {
        selectedData = (String) table.getValueAt(selectedRow[i], selectedColumns[j]);
      }
    }
    System.out.println("Selected: " + selectedData);
  }

});

see here.

Also, It can be done with LINQ

var str = "Hello@Hello&Hello(Hello)";
var characters = str.Select(c => char.IsLetter(c) ? c : ',')).ToArray();             
var output = new string(characters);
Console.WriteLine(output);

I've found another option: spinner definition in the layout file

<Spinner android:id="@+id/spinner"
    android:layout_width="fill_parent"
    android:drawSelectorOnTop="true"
    android:prompt="@string/spin"
    android:entries="@array/spinnerItems"
/>

Items definition in the file array.xml:

<resources>
    <string-array name="spinnerItems">
        <item>item1</item>
        <item>item2</item>
        <item>item3</item>
        <item>item4</item>
    </string-array>
</resources>

If you need to know the class name that was called from inside a class, and don't want the namespace, you can use this one

$calledClass = get_called_class();
$name = strpos($calledClass, '\\') === false ?
    $calledClass : substr($calledClass, strrpos($calledClass, '\\') + 1);

This is great when you have a method inside a class which is extended by other classes. Furthermore, this also works if namespaces aren't used at all.

Example:

<?php
namespace One\Two {
    class foo
    {
        public function foo()
        {
            $calledClass = get_called_class();
            $name = strpos($calledClass, '\\') === false ?
                $calledClass : substr($calledClass, strrpos($calledClass, '\\') + 1);

            var_dump($name);
        }
    }
}

namespace Three {
    class bar extends \One\Two\foo
    {
        public function bar()
        {
            $this->foo();
        }
    }
}

namespace {
    (new One\Two\foo)->foo();
    (new Three\bar)->bar();
}

// test.php:11:string 'foo' (length=3)
// test.php:11:string 'bar' (length=3)

This is what the code would look like in a batch file(tested, works):

powershell -Command "& {set-location 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings'; set-location ZoneMap\Domains; new-item SERVERNAME; set-location SERVERNAME; new-itemproperty . -Name http -Value 2 -Type DWORD;}"

Based on the information from:

http://dmitrysotnikov.wordpress.com/2008/06/27/powershell-script-in-a-bat-file/

EDIT: as of Java8 you'd better use Files class:

Path resultingPath = Files.createDirectories('A/B');

I don't know if this ultimately fixes your problem but class File has method mkdirs() which fully creates the path specified by the file.

File f = new File("/A/B/");
f.mkdirs();

You should look at Computed Properties

In your code sample, perimeter is a property not backed up by a class variable, instead its value is computed using the get method and stored via the set method - usually referred to as getter and setter.

When you use that property like this:

var cp = myClass.perimeter

you are invoking the code contained in the get code block, and when you use it like this:

myClass.perimeter = 5.0

you are invoking the code contained in the set code block, where newValue is automatically filled with the value provided at the right of the assignment operator.

Computed properties can be readwrite if both a getter and a setter are specified, or readonly if the getter only is specified.

To see all tables:

.tables

To see a particular table:

.schema [tablename]

If you are using bootstrap.js then the below code might be useful. This is very simple. Dont have to write anything in js to invoke the pop-up.

I had trouble at first with setting the colors for a WPF applications controls. It appears it does not include System.Windows.Media by default but does include Windows.UI.Xaml.Media, which has some pre-filled colors.

I ended up using the following line of code to get it to work:

grid.Background.SetValue(SolidColorBrush.ColorProperty, Windows.UI.Colors.CadetBlue);

You should be able to change grid.Background to most other controls and then change CadetBlue to any of the other colors it provides.

Without jquery or anything like that beacuse why not ?

var loaded=0;
var loaded1min=0;
document.addEventListener("DOMContentLoaded", function(event) {
   loaded=1;
    setTimeout(function () {
      loaded1min=1;
    }, 60000);
});

use

window.location.replace("login.php");

or simply window.location("login.php");

It is better than using window.location.href =, because replace() does not put the originating page in the session history, meaning the user won't get stuck in a never-ending back-button fiasco. If you want to simulate someone clicking on a link, use location.href. If you want to simulate an HTTP redirect, use location.replace.

There are several places on Windows where SVN will place cached credentials depending on system configuration. Read SVNBook | Client Credentials.

• The main credential store is located in %APPDATA%\Subversion\auth and you can run svn auth command to view and manage its contents.

• You can also run cmdkey to view the credentials stored in Windows Credential Manager.

• If your SVN server is integrated with Active Directory and supports Integrated Windows Authentication such as VisualSVN Server, your Windows logon credentials are used for authentication, but they are not cached. You can run whoami to find out your user account name.

Here is a working example in both Javascript and jQuery:

http://jsfiddle.net/GuLYN/312/

//In jQuery
$("#calculate").click(function() {
    var num = parseFloat($("#textbox").val());
    var new_num = $("#textbox").val(num.toFixed(2));
});


// In javascript
document.getElementById('calculate').onclick = function() {
    var num = parseFloat(document.getElementById('textbox').value);
    var new_num = num.toFixed(2);
    document.getElementById('textbox').value = new_num;
};
?

If SQL Server Service is running as Local System, than make sure that the folder containing databases should have FULL CONTROL PERMISSION for the Local System account.

This worked for me.

Based on @davioooh answer. This code is worked for me.

ListObjectsRequest listObjectsRequest = new ListObjectsRequest().withBucketName("your-bucket")
            .withPrefix("your/folder/path/").withDelimiter("/");

i have programmed a small method for it.. its a generalize function..

    public static void printDataTable(DataTable tbl)
    {
        string line = "";
        foreach (DataColumn item in tbl.Columns)
        {
            line += item.ColumnName +"   ";
        }
        line += "\n";
        foreach (DataRow row in tbl.Rows)
        {
            for (int i = 0; i < tbl.Columns.Count; i++)
            {
                line += row[i].ToString() + "   ";
            }
            line += "\n";
        }
        Console.WriteLine(line) ;
    }

I have encountered this with Maven projects too. This is what I had to do to get around the problem:

First update your web.xml

<web-app xmlns="http://java.sun.com/xml/ns/javaee" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
                    http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
                    version="3.0">
<display-name>Servlet 3.0 Web Application</display-name>

Then right click on your project and select Properties -> Project Facets In there you will see the version of your Dynamic Web Module. This needs to change from version 2.3 or whatever to version 2.5 or above (I chose 3.0).

However to do this I had to uncheck the tick box for Dynamic Web Module -> Apply, then do a Maven Update on the project. Go back into the Project Facets window and it should already match your web.xml configuration - 3.0 in my case. You should be able to change it if not.

If this does not work for you then try right-clicking on the Dynamic Web Module Facet and select change version (and ensure it is not locked).

Or you can follow this steps:

1. Window > Show View > Other > General > navigator
2. There is a .settings folder under your project directory
3. Change the dynamic web module version in this line to 3.0
4. Change the Java version in this line to 1.5 or higher

don't forget to update your project

Hope that works!

I used images2gif.py which was easy to use. It did seem to double the file size though..

26 110kb PNG files, I expected 26*110kb = 2860kb, but my_gif.GIF was 5.7mb

Also because the GIF was 8bit, the nice png's became a little fuzzy in the GIF

Here is the code I used:

__author__ = 'Robert'
from images2gif import writeGif
from PIL import Image
import os

file_names = sorted((fn for fn in os.listdir('.') if fn.endswith('.png')))
#['animationframa.png', 'animationframb.png', 'animationframc.png', ...] "

images = [Image.open(fn) for fn in file_names]

print writeGif.__doc__
# writeGif(filename, images, duration=0.1, loops=0, dither=1)
#    Write an animated gif from the specified images.
#    images should be a list of numpy arrays of PIL images.
#    Numpy images of type float should have pixels between 0 and 1.
#    Numpy images of other types are expected to have values between 0 and 255.


#images.extend(reversed(images)) #infinit loop will go backwards and forwards.

filename = "my_gif.GIF"
writeGif(filename, images, duration=0.2)
#54 frames written
#
#Process finished with exit code 0

Here are 3 of the 26 frames:

shrinking the images reduced the size:

size = (150,150)
for im in images:
    im.thumbnail(size, Image.ANTIALIAS)

Try this

$('#thisElement .classToSelect').each(function(i){
         // do stuff
});

Hope it will help

I found this link helpful

I personally use these following alias in bash

in ~/.gitconfig file

[alias]
    pushup = "!git push --set-upstream origin $(git symbolic-ref --short HEAD)"

and in ~/.bashrc or ~/.zshrc file

alias gpo="git pushup"
alias gpof="gpo -f"
alias gf="git fetch"
alias gp="git pull"

you can configure IIS in IIS Mgr to use EVERY port between 1 and 65535 as long it is not used by any other application

This is how i registered my domain:

sudo letsencrypt --apache -d mydomain.com

Then it was possible to use the same command with additional domains and follow the instructions:

sudo letsencrypt --apache -d mydomain.com,x.mydomain.com,y.mydomain.com

Easiest: http://www.addthis.com/

Best? Well. probably not, But If you don't want to design something bespoke this is the best there is...

Here's my simple solution for the two basic cases differing on whether you want to load the graph from file or build it during runtime.

This answer holds for Tensorflow 0.12+ (including 1.0).

Rebuilding the graph in code

Saving

graph = ... # build the graph
saver = tf.train.Saver()  # create the saver after the graph
with ... as sess:  # your session object
    saver.save(sess, 'my-model')

Loading

graph = ... # build the graph
saver = tf.train.Saver()  # create the saver after the graph
with ... as sess:  # your session object
    saver.restore(sess, tf.train.latest_checkpoint('./'))
    # now you can use the graph, continue training or whatever

Loading also the graph from a file

When using this technique, make sure all your layers/variables have explicitly set unique names. Otherwise Tensorflow will make the names unique itself and they'll be thus different from the names stored in the file. It's not a problem in the previous technique, because the names are "mangled" the same way in both loading and saving.

Saving

graph = ... # build the graph

for op in [ ... ]:  # operators you want to use after restoring the model
    tf.add_to_collection('ops_to_restore', op)

saver = tf.train.Saver()  # create the saver after the graph
with ... as sess:  # your session object
    saver.save(sess, 'my-model')

Loading

with ... as sess:  # your session object
    saver = tf.train.import_meta_graph('my-model.meta')
    saver.restore(sess, tf.train.latest_checkpoint('./'))
    ops = tf.get_collection('ops_to_restore')  # here are your operators in the same order in which you saved them to the collection

Formatting your code a bit, you have only closed the inner hover function. You have not closed the outer parts, marked below:

$(// missing closing)
 function() { // missing closing }
     $("#mewlyDiagnosed").hover(
        function() {
            $("#mewlyDiagnosed").animate({'height': '237px', 'top': "-75px"});
        }, 
        function() {
            $("#mewlyDiagnosed").animate({'height': '162px', 'top': "0px"});
        });

The only thing that appears to work is to set flex-wrap: wrap; on the container and them somehow make the child you want to break out after to fill the full width, so width: 100%; should work.

If, however, you can't stretch the element to 100% (for example, if it's an <img>), you can apply a margin to it, like width: 50px; margin-right: calc(100% - 50px).

To add the list values to string array using C# without using ToArray() method

        List<string> list = new List<string>();
        list.Add("one");
        list.Add("two");
        list.Add("three");
        list.Add("four");
        list.Add("five");
        string[] values = new string[list.Count];//assigning the count for array
        for(int i=0;i<list.Count;i++)
        {
            values[i] = list[i].ToString();
        }

Output of the value array contains:

one

two

three

four

five

In my case I had to add FormsModule and ReactiveFormsModule to the shared.module.ts too:

(thanks to @Undrium for the code example):

import { NgModule }                                 from '@angular/core';
import { CommonModule }                             from '@angular/common';
import { FormsModule, ReactiveFormsModule }         from '@angular/forms';

@NgModule({
  imports:      [
    CommonModule,
    ReactiveFormsModule
  ],
  declarations: [],
  exports: [
    CommonModule,
    FormsModule,
    ReactiveFormsModule
  ]
})
export class SharedModule { }

Here is an example using the DOM cookie API (https://developer.mozilla.org/en-US/docs/Web/API/Document/cookie), so we can see for ourselves the behavior.

If we execute the following JavaScript:

document.cookie = "key=value"

It appears to be the same as executing:

document.cookie = "key=value;domain=mydomain.com"

The cookie key becomes available (only) on the domain mydomain.com.

Now, if you execute the following JavaScript on mydomain.com:

document.cookie = "key=value;domain=.mydomain.com"

The cookie key becomes available to mydomain.com as well as subdomain.mydomain.com.

Finally, if you were to try and execute the following on subdomain.mydomain.com:

document.cookie = "key=value;domain=.mydomain.com"

Does the cookie key become available to subdomain.mydomain.com? I was a bit surprised that this is allowed; I had assumed it would be a security violation for a subdomain to be able to set a cookie on a parent domain.

with UnionTable as  
(
    SELECT a.id, a.time FROM dbo.a
    UNION
    SELECT b.id, b.time FROM dbo.b
) SELECT id FROM UnionTable GROUP BY id

You can run npm commands directly in terminal (ctrl + `). Make sure that terminal has cmd.exe as the shell selected.

You can default cmd.exe as your shell by following these steps.

1. ctrl+Shift+p
2. Type > Select Default Shell + Enter
3. Select > Command Prompt ...cmd.exe
4. Restart VS Code.

If you need a recursive search, you have a variety of options. You should consider ack.

Failing that, if you have GNU find and xargs:

find . -name '*.cc' -print0 -o -name '*.h' -print0 | xargs -0 grep hello /dev/null

The use of /dev/null ensures you get file names printed; the -print0 and -0 deals with file names containing spaces (newlines, etc).

If you don't have obstreperous names (with spaces etc), you can use:

find . -name '*.*[ch]' -print | xargs grep hello /dev/null

This might pick up a few names you didn't intend, because the pattern match is fuzzier (but simpler), but otherwise works. And it works with non-GNU versions of find and xargs.

a very common try_files line which can be applied on your condition is

location / {
    try_files $uri $uri/ /test/index.html;
}

you probably understand the first part, location / matches all locations, unless it's matched by a more specific location, like location /test for example

The second part ( the try_files ) means when you receive a URI that's matched by this block try $uri first, for example http://example.com/images/image.jpg nginx will try to check if there's a file inside /images called image.jpg if found it will serve it first.

Second condition is $uri/ which means if you didn't find the first condition $uri try the URI as a directory, for example http://example.com/images/, ngixn will first check if a file called images exists then it wont find it, then goes to second check $uri/ and see if there's a directory called images exists then it will try serving it.

Side note: if you don't have autoindex on you'll probably get a 403 forbidden error, because directory listing is forbidden by default.

EDIT: I forgot to mention that if you have index defined, nginx will try to check if the index exists inside this folder before trying directory listing.

Third condition /test/index.html is considered a fall back option, (you need to use at least 2 options, one and a fall back), you can use as much as you can (never read of a constriction before), nginx will look for the file index.html inside the folder test and serve it if it exists.

If the third condition fails too, then nginx will serve the 404 error page.

Also there's something called named locations, like this

location @error {
}

You can call it with try_files like this

try_files $uri $uri/ @error;

TIP: If you only have 1 condition you want to serve, like for example inside folder images you only want to either serve the image or go to 404 error, you can write a line like this

location /images {
    try_files $uri =404;
}

which means either serve the file or serve a 404 error, you can't use only $uri by it self without =404 because you need to have a fallback option.
You can also choose which ever error code you want, like for example:

location /images {
    try_files $uri =403;
}

This will show a forbidden error if the image doesn't exist, or if you use 500 it will show server error, etc ..

This should be a short & simple copy & paste piece of code example of the above responses. Hopefully this helps.

To select manually the buttons with the trackball use:

myListView.setItemsCanFocus(true);

And to disable the focus on the whole list items:

myListView.setFocusable(false);
myListView.setFocusableInTouchMode(false);
myListView.setClickable(false);

It works fine for me, I can click on buttons with touchscreen and also alows focus an click using keypad

Just recently experienced this:

System.ServiceModel.CommunicationException:

An error occurred while making the HTTP request to http://example.com/WebServices/SomeService.svc. This could be due to the fact that the server certificate is not configured properly with HTTP.SYS in the HTTPS case. This could also be caused by a mismatch of the security binding between the client and the server.

---> System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a send.

---> System.IO.IOException: Unable to write data to the transport connection: An existing connection was forcibly closed by the remote host.

Our license of the bluecoat proxy was expired! so it was not possible to to reach the external party (internet).

How about putting the checkbox into the label, making the label automatically "click sensitive" for the check box, and giving the checkbox a onchange event?

<label ..... ><input type="checkbox" onchange="toggleCheckbox(this)" .....> 

function toggleCheckbox(element)
 {
   element.checked = !element.checked;
 }

This will additionally catch users using a keyboard to toggle the check box, something onclick would not.

Use the keyword size instead of fontsize.

You do not need the latex2exp package to do what you wanted to do. The following code would do the trick.

ggplot(smr, aes(Fuel.Rate, Eng.Speed.Ave., color=Eng.Speed.Max.)) + 
  geom_point() + 
  labs(title=expression("Fuel Efficiency"~(alpha*Omega)), 
color=expression(alpha*Omega), x=expression(Delta~price))

Also, some comments (unanswered as of this point) asked about putting an asterisk (*) after a Greek letter. expression(alpha~"*") works, so I suggest giving it a try.

More comments asked about getting ? Price and I find the most straightforward way to achieve that is expression(Delta~price)). If you need to add something before the Greek letter, you can also do this: expression(Indicative~Delta~price) which gets you:

I don't see how if(!empty($var)) can create confusion, but I do agree that if ($var) is simpler. – vanneto Mar 8 '12 at 13:33

Because empty has the specific purpose of suppressing errors for nonexistent variables. You don't want to suppress errors unless you need to. The Definitive Guide To PHP's isset And empty explains the problem in detail. – deceze? Mar 9 '12 at 1:24

Focusing on the error suppression part, if the variable is an array where a key being accessed may or may not be defined:

1. if($web['status']) would produce:

   Notice: Undefined index: status

2. To access that key without triggering errors:
   1. if(isset($web['status']) && $web['status']) (2nd condition is not tested if the 1st one is FALSE) OR
   2. if(!empty($web['status'])).

However, as deceze? pointed out, a truthy value of a defined variable makes !empty redundant, but you still need to remember that PHP assumes the following examples as FALSE:

• null
• '' or ""
• 0.0
• 0
• '0' or "0"
• '0' + 0 + !3

So if zero is a meaningful status that you want to detect, you should actually use string and numeric comparisons:

3. Error free and zero detection:

   if(isset($web['status'])){
     if($web['status'] === '0' || $web['status'] === 0 ||
        $web['status'] === 0.0 || $web['status']) {
       // not empty: use the value
     } else {
       // consider it as empty, since status may be FALSE, null or an empty string
     }
   }
   

   The generic condition ($web['status']) should be left at the end of the entire statement.

The input type=email page of the www.w3.org site notes that an email address is any string which matches the following regular expression:

/^[a-zA-Z0-9.!#$%&’*+/=?^_`{|}~-]+@[a-zA-Z0-9-]+(?:\.[a-zA-Z0-9-]+)*$/

Use the required attribute and a pattern attribute to require the value to match the regex pattern.

<input
    type="text"
    pattern="/^[a-zA-Z0-9.!#$%&’*+/=?^_`{|}~-]+@[a-zA-Z0-9-]+(?:\.[a-zA-Z0-9-]+)*$/"
    required

This is the Best of all methods i came across

Clone just the repository's .git folder (excluding files as they are already in existing-dir) into an empty temporary directory

1. git clone --no-checkout repo-path-to-clone existing-dir/existing-dir.tmp //might want --no-hardlinks for cloning local repo

Move the .git folder to the directory with the files. This makes existing-dir a git repo.

2. mv existing-dir/existing-dir.tmp/.git existing-dir/

Delete the temporary directory

3. rmdir existing-dir/existing-dir.tmp

4. cd existing-dir

Git thinks all files are deleted, this reverts the state of the repo to HEAD.

WARNING: any local changes to the files will be lost.

5. git reset --mixed HEAD

Ah, got it myselfs.
The quirks and quarks of LINQ-2-entities.
This looks most understandable:

var query2 = (
    from users in Repo.T_Benutzer
    from mappings in Repo.T_Benutzer_Benutzergruppen
        .Where(mapping => mapping.BEBG_BE == users.BE_ID).DefaultIfEmpty()
    from groups in Repo.T_Benutzergruppen
        .Where(gruppe => gruppe.ID == mappings.BEBG_BG).DefaultIfEmpty()
    //where users.BE_Name.Contains(keyword)
    // //|| mappings.BEBG_BE.Equals(666)  
    //|| mappings.BEBG_BE == 666 
    //|| groups.Name.Contains(keyword)

    select new
    {
         UserId = users.BE_ID
        ,UserName = users.BE_User
        ,UserGroupId = mappings.BEBG_BG
        ,GroupName = groups.Name
    }

);


var xy = (query2).ToList();

Remove the .DefaultIfEmpty(), and you get an inner join.
That was what I was looking for.

For radio and radio group:

$(document).ready(function() {
    $(document).find("input:checked[type='radio']").addClass('bounce');   
    $("input[type='radio']").click(function() {
        $(this).prop('checked', false);
        $(this).toggleClass('bounce');

        if( $(this).hasClass('bounce') ) {
            $(this).prop('checked', true);
            $(document).find("input:not(:checked)[type='radio']").removeClass('bounce');
        }
    });
});

You can cast your JToken to a JObject and then use the Properties() method to get a list of the object properties. From there, you can get the names rather easily.

Something like this:

string json =
@"{
    ""ADDRESS_MAP"":{

        ""ADDRESS_LOCATION"":{
            ""type"":""separator"",
            ""name"":""Address"",
            ""value"":"""",
            ""FieldID"":40
        },
        ""LOCATION"":{
            ""type"":""locations"",
            ""name"":""Location"",
            ""keyword"":{
                ""1"":""LOCATION1""
            },
            ""value"":{
                ""1"":""United States""
            },
            ""FieldID"":41
        },
        ""FLOOR_NUMBER"":{
            ""type"":""number"",
            ""name"":""Floor Number"",
            ""value"":""0"",
            ""FieldID"":55
        },
        ""self"":{
            ""id"":""2"",
            ""name"":""Address Map""
        }
    }
}";

JToken outer = JToken.Parse(json);
JObject inner = outer["ADDRESS_MAP"].Value<JObject>();

List<string> keys = inner.Properties().Select(p => p.Name).ToList();

foreach (string k in keys)
{
    Console.WriteLine(k);
}

Output:

ADDRESS_LOCATION
LOCATION
FLOOR_NUMBER

There's the htaccess tester.

It shows which conditions were tested for a certain URL, which ones met the criteria and which rules got executed.

It seems to have some glitches, though.

Given that what you want is to determine the full id of the element based upon just the prefix, you're going to have to do a search of the entire DOM (or at least, a search of an entire subtree if you know of some element that is always guaranteed to contain your target element). You can do this with something like:

function findChildWithIdLike(node, prefix) {
    if (node && node.id && node.id.indexOf(prefix) == 0) {
        //match found
        return node;
    }

    //no match, check child nodes
    for (var index = 0; index < node.childNodes.length; index++) {
        var child = node.childNodes[index];
        var childResult = findChildWithIdLike(child, prefix);
        if (childResult) {
            return childResult;
        }
    }
};

Here is an example: http://jsfiddle.net/xwqKh/

Be aware that dynamic element ids like the ones you are working with are typically used to guarantee uniqueness of element ids on a single page. Meaning that it is likely that there are multiple elements that share the same prefix. Probably you want to find them all.

If you want to find all of the elements that have a given prefix, instead of just the first one, you can use something like what is demonstrated here: http://jsfiddle.net/xwqKh/1/

For Mac (and I assume Linux)...

If the zip archive contains a single file, you can use the bash command funzip, in conjuction with fread from the data.table package:

library(data.table)
dt <- fread("curl http://www.newcl.org/data/zipfiles/a1.zip | funzip")

In cases where the archive contains multiple files, you can use tar instead to extract a specific file to stdout:

dt <- fread("curl http://www.newcl.org/data/zipfiles/a1.zip | tar -xf- --to-stdout *a1.dat")

    return redirect()->intended(Session::pull('referrer'));
    /*return redirect()->intended($this->redirectPath()); /*Larevel default*/
}

And import namespace: use Session;

If you have not made any changes to the file app\Http\Controllers\Auth\AurhController.php, you can just replace it with the file from the GitHub

API is specifications on how to do something, an interface, such as "The railroad tracks are four feet apart, and the metal bar is 1 inch wide" Now that you have the API you can now build a train that will fit on those railroad tracks if you want to go anywhere. API is just information on how to build your code, it doesn't do anything.

SDK is some package of actual tools that already worried about the specifications. "Here's a train, some coal, and a maintenance man. Use it to go from place to place" With the SDK you don't worry about specifics. An SDK is actual code, it can be used by itself to do something, but of course, the train won't start up spontaneously, you still have to get a conductor to control the train.

SDKs also have their own APIs. "If you want to power the train put coal in it", "Pull the blue lever to move the train.", "If the train starts acting funny, call the maintenance man" etc.

ok just to answer the original question:

you can get the padding as a usable integer like this:

var padding = parseInt($("myId").css("padding-top").replace("ems",""));

If you have defined another measurement like px just replace "ems" with "px". parseInt interprets the stringpart as a wrong value so its important to replace it with ... nothing.

The fastest way for LocalDateTime -> Date is:

Date.from(ldt.toInstant(ZoneOffset.UTC))

You should read it recursively, some time ago I had the same question and solve with this code:

public void proccessMenuNodeList(NodeList nl, JMenuBar menubar) {
    for (int i = 0; i < nl.getLength(); i++) {
        proccessMenuNode(nl.item(i), menubar);
    }
}

public void proccessMenuNode(Node n, Container parent) {
    if(!n.getNodeName().equals("menu"))
        return;
    Element element = (Element) n;
    String type = element.getAttribute("type");
    String name = element.getAttribute("name");
    if (type.equals("menu")) {
        NodeList nl = element.getChildNodes();
        JMenu menu = new JMenu(name);

        for (int i = 0; i < nl.getLength(); i++)
            proccessMenuNode(nl.item(i), menu);

        parent.add(menu);
    } else if (type.equals("item")) {
        JMenuItem item = new JMenuItem(name);
        parent.add(item);
    }
}

Probably you can adapt it for your case.

i think, this simple example should you explain the diffs between strong and dynamic typing:

>>> tup = ('1', 1, .1)
>>> for item in tup:
...     type(item)
...
<type 'str'>
<type 'int'>
<type 'float'>
>>>

java:

public static void main(String[] args) {
        int i = 1;
        i = "1"; //will be error
        i = '0.1'; // will be error
    }

Used below code in similar situation

driver.manage().timeouts().pageLoadTimeout(60, TimeUnit.SECONDS);

and embedded driver.get code in a try catch, which solved the issue of loading pages which were taking more than 1 minute.

After hours of research this solution worked for me:

(disclaimer: results may vary due to circumstances)

the Library not found -lPods-(someCocoapod) error was due to multiple entries in the :

Settings(Target) > Build Settings > Linking > 'Other Linker Flags'

A lot of other posts had me look there and I would see changes to the error when I messed around with the entries, but I kept getting some variation on the same error.

Too many hours lost ...

My Fix:

remove the -lPods-(someCocoaPod) lines in the 'Other Linker Flags' list BUT only if $(inherited) is at the top. At first I was unsure, but the reassuring sign was that I still saw references to my cocoapods when I left the edit mode(inherited). I tested in debug and release, both of which were giving me errors, and the problem was immediately resolved.

You're looking for an ellipsoid formula.

The best place I've found to start coding is based on the Geo::Ellipsoid library from CPAN. It gives you a baseline to create your tests off of and to compare your results with its results. I used it as the basis for a similar library for PHP at my previous employer.

Geo::Ellipsoid

Take a look at the location method. Call it twice and you've got your bbox.

You didn't post what language you were using. There may already be a geocoding library available for you.

Oh, and if you haven't figured it out by now, Google maps uses the WGS84 ellipsoid.

import warnings
warnings.warn("Warning...........Message")

See the python documentation: here

I also recently had this problem and I solved it by rebooting Android Studio. But my friend had to have the original cable for his device, no other cables worked.

I presume you want to copy C:\OtherFolder\fileToCheck.bat to C:\MyFolder if the existing file in C:\MyFolder is either missing entirely, or if it is missing "stringToCheck".

FINDSTR sets ERRORLEVEL to 0 if the string is found, to 1 if it is not. It also sets errorlevel to 1 if the file is missing. It also prints out each line that matches. Since you are trying to use it as a condition, I presume you don't need or want to see any of the output. The 1st thing I would suggest is to redirect both the normal and error output to nul using >nul 2>&1.

Solution 1 (mostly the same as previous answers)

You can use IF ERRORRLEVEL N to check if the errorlevel is >= N. Or you can use IF NOT ERRORLEVEL N to check if errorlevel is < N. In your case you want the former.

findstr /c:"stringToCheck" "c:\MyFolder\fileToCheck.bat" >nul 2>&1
if errorlevel 1 xcopy "C:\OtherFolder\fileToCheck.bat" "c:\MyFolder"

Solution 2

You can test for a specific value of errorlevel by using %ERRORLEVEL%. You can probably check if the value is equal to 1, but it might be safer to check if the value is not equal to 0, since it is only set to 0 if the file exists and it contains the string.

findstr /c:"stringToCheck" "c:\MyFolder\fileToCheck.bat" >nul 2>&1
if not %errorlevel% == 0 xcopy "C:\OtherFolder\fileToCheck.bat" "c:\MyFolder"

or

findstr /c:"stringToCheck" "c:\MyFolder\fileToCheck.bat" >nul 2>&1
if %errorlevel% neq 0 xcopy "C:\OtherFolder\fileToCheck.bat" "c:\MyFolder"

Solution 3

There is a very compact syntax to conditionally execute a command based on the success or failure of the previous command: cmd1 && cmd2 || cmd3 which means execute cmd2 if cmd1 was successful (errorlevel=0), else execute cmd3 if cmd1 failed (errorlevel<>0). You can use && alone, or || alone. All the commands need to be on the same line. If you need to conditionally execute multiple commands you can use multiple lines by adding parentheses

cmd1 && (
   cmd2
   cmd3
) || (
   cmd4
   cmd5
)

So for your case, all you need is

findstr /c:"stringToCheck" "c:\MyFolder\fileToCheck.bat" >nul 2>&1 || xcopy "C:\OtherFolder\fileToCheck.bat" "c:\MyFolder"

But beware - the || will respond to the return code of the last command executed. In my earlier pseudo code the || will obviously fire if cmd1 fails, but it will also fire if cmd1 succeeds but then cmd3 fails.

So if your success block ends with a command that may fail, then you should append a harmless command that is guaranteed to succeed. I like to use (CALL ), which is harmless, and always succeeds. It also is handy that it sets the ERRORLEVEL to 0. There is a corollary (CALL) that always fails and sets ERRORLEVEL to 1.

In terminal it's better to run installation of the cocoa pods with "sudo". In other case I'm getting an error: "You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory."

So the solution is:

sudo gem install cocoapods

unsigned char c;

for( int i = 7; i >= 0; i-- ) {
    printf( "%d", ( c >> i ) & 1 ? 1 : 0 );
}

printf("\n");

Explanation:

With every iteration, the most significant bit is being read from the byte by shifting it and binary comparing with 1.

For example, let's assume that input value is 128, what binary translates to 1000 0000. Shifting it by 7 will give 0000 0001, so it concludes that the most significant bit was 1. 0000 0001 & 1 = 1. That's the first bit to print in the console. Next iterations will result in 0 ... 0.

I had a false response for the following:

fputs($connection, 'STARTTLS'.$newLine);

turns out I use the wrong connection variable, so I just had to change it to:

fputs($smtpConnect, 'STARTTLS'.$newLine);

If using TLS remember to put HELO before and after:

fputs($smtpConnect, 'HELO '.$localhost . $newLine);
$response = fgets($smtpConnect, 515);
if($secure == 'tls')
{
    fputs($smtpConnect, 'STARTTLS'.$newLine);
    $response = fgets($smtpConnect, 515);
stream_socket_enable_crypto($smtpConnect, true, STREAM_CRYPTO_METHOD_TLS_CLIENT);

// Say hello again!
    fputs($smtpConnect, 'HELO '.$localhost . $newLine);
    $response = fgets($smtpConnect, 515);
}

I too got this problem and all solutions given above either failed or were not applicable due to client webservice restrictions.

For this, I added an iframe in my page which resided in the client;s server. So when we post our data to the iframe and the iframe then posts it to the webservice. Hence the cross-domain referencing is eliminated.

We added a 2-way origin check to confirm only authorized page posts data to and from the iframe.

Hope it helps

<iframe style="display:none;" id='receiver' name="receiver" src="https://iframe-address-at-client-server">
 </iframe>

//send data to iframe
var hiddenFrame = document.getElementById('receiver').contentWindow;
hiddenFrame.postMessage(JSON.stringify(message), 'https://client-server-url');

//The iframe receives the data using the code:
window.onload = function () {
    var eventMethod = window.addEventListener ? "addEventListener" : "attachEvent";
    var eventer = window[eventMethod];
    var messageEvent = eventMethod == "attachEvent" ? "onmessage" : "message";
    eventer(messageEvent, function (e) {
        var origin = e.origin;
        //if origin not in pre-defined list, break and return
        var messageFromParent = JSON.parse(e.data);
        var json = messageFromParent.data;

        //send json to web service using AJAX   
        //return the response back to source
        e.source.postMessage(JSON.stringify(aJAXResponse), e.origin);
    }, false);
}

The DataRow has also an indexer:

Object cellValue = dt.Rows[i][j];

But i would prefer the strongly typed Field extension method which also supports nullable types:

int number = dt.Rows[i].Field<int>(j);

or even more readable and less error-prone with the name of the column:

double otherNumber = dt.Rows[i].Field<double>("DoubleColumn");

For version v2.2.2 and newer

In version v2.2.2 and up, name property no longer exists and it shouldn't be used to define the route. path should be used instead of name and no leading slash is needed on the path. In this case use path: '404' instead of path: '/404':

 {path: '404', component: NotFoundComponent},
 {path: '**', redirectTo: '/404'}

For versions older than v2.2.2

you can use {path: '/*path', redirectTo: ['redirectPathName']}:

{path: '/home/...', name: 'Home', component: HomeComponent}
{path: '/', redirectTo: ['Home']},
{path: '/user/...', name: 'User', component: UserComponent},
{path: '/404', name: 'NotFound', component: NotFoundComponent},

{path: '/*path', redirectTo: ['NotFound']}

if no path matches then redirect to NotFound path

If df is a pandas.DataFrame then df['new_col']= Series list_object of length len(df) will add the or Series list_object as a column named 'new_col'. df['new_col']= scalar (such as 5 or 6 in your case) also works and is equivalent to df['new_col']= [scalar]*len(df)

So a two-line code serves the purpose:

df = pd.DataFrame({'a':[1, 2], 'b':[3, 4]})
s = pd.Series({'s1':5, 's2':6})
for x in s.index:    
    df[x] = s[x]

Output: 
   a  b  s1  s2
0  1  3   5   6
1  2  4   5   6

For Me I just wanted to see the error in my VBA application so in the function I created the below code..

Function Database_FileRpt
'-------------------------

'-------------------------

' Create_DailyReport_Action and code


CleanFail:

'*************************************

import os
os.listdir("somedirectory")

will return a list of all files and directories in "somedirectory".

There are two general approaches here:

• Check each array item for nan and take any.
• Apply some cumulative operation that preserves nans (like sum) and check its result.

While the first approach is certainly the cleanest, the heavy optimization of some of the cumulative operations (particularly the ones that are executed in BLAS, like dot) can make those quite fast. Note that dot, like some other BLAS operations, are multithreaded under certain conditions. This explains the difference in speed between different machines.

import numpy
import perfplot


def min(a):
    return numpy.isnan(numpy.min(a))


def sum(a):
    return numpy.isnan(numpy.sum(a))


def dot(a):
    return numpy.isnan(numpy.dot(a, a))


def any(a):
    return numpy.any(numpy.isnan(a))


def einsum(a):
    return numpy.isnan(numpy.einsum("i->", a))


perfplot.show(
    setup=lambda n: numpy.random.rand(n),
    kernels=[min, sum, dot, any, einsum],
    n_range=[2 ** k for k in range(20)],
    logx=True,
    logy=True,
    xlabel="len(a)",
)

I recommend always using a named range (as you have suggested you are doing) because if any columns or rows are added or deleted, the name reference will update, whereas if you hard code the cell reference (eg "H1" as suggested in one of the responses) in VBA, then it will not update and will point to the wrong cell.

So

Range("RefNo") = InputBox("....") 

is safer than

Range("H1") = InputBox("....") 

You can set the value of several cells, too.

Range("Results").Resize(10,3) = arrResults()

where arrResults is an array of at least 10 rows & 3 columns (and can be any type). If you use this, put this

Option Base 1

at the top of the VBA module, otherwise VBA will assume the array starts at 0 and put a blank first row and column in the sheet. This line makes all arrays start at 1 as a default (which may be abnormal in most languages but works well with spreadsheets).

Use a CSS method to force wrap a string that has no white-spaces. Three methods:

1) Use the CSS white-space property. To cover browser inconsistencies, you have to declare it several ways. So just put your looooong string into some block level element (e.g., div, pre, p) and give that element the following css:

some_block_level_tag {
    white-space: pre;           /* CSS 2.0 */
    white-space: pre-wrap;      /* CSS 2.1 */
    white-space: pre-line;      /* CSS 3.0 */
    white-space: -pre-wrap;     /* Opera 4-6 */
    white-space: -o-pre-wrap;   /* Opera 7 */
    white-space: -moz-pre-wrap; /* Mozilla */
    white-space: -hp-pre-wrap;  /* HP Printers */
    word-wrap: break-word;      /* IE 5+ */
}

2) use the force-wrap mixin from Compass.

3) I was just looking into this as well and I think might also work (but I need to test browser support more completely):

.break-me {
    word-wrap: break-word;
    overflow-wrap: break-word;
}

Reference: wrapping content

I slightly modified the example from Microsoft: https://support.microsoft.com/en-us/kb/319401

This method will only sort once to sort ascending. My modifications make it sort both ways.

public class ListViewItemComparer : IComparer
{
    private int col;
    bool bAsc = false;
    public ListViewItemComparer()
    {
        col = 0;
    }
    public ListViewItemComparer(int column, bool b)
    {
        col = column;
        bAsc = b;
    }
    public int Compare(object x, object y)
    {
        if (bAsc)
        {
            return String.Compare(((ListViewItem)x).SubItems[col].Text, ((ListViewItem)y).SubItems[col].Text);
            bAsc = false;
        }
        else
        {
            return String.Compare(((ListViewItem)y).SubItems[col].Text, ((ListViewItem)x).SubItems[col].Text);
            bAsc = true;
        }
    }

}

Then I create an object of this class whenever a column header is clicked

        bool sortAscending = false;
        private void inventoryList_ColumnClick(object sender, ColumnClickEventArgs e)
        {

            if (!sortAscending)
            {
                sortAscending = true;
            }
            else
            {
                sortAscending = false;
            }
            this.inventoryList.ListViewItemSorter = new ListViewItemComparer(e.Column, sortAscending);

        }

DEBUG is the lowest restricted java logging level and we should write everything we need to debug an application, this java logging mode should only be used on Development and Testing environment and must not be used in production environment.

INFO is more restricted than DEBUG java logging level and we should log messages which are informative purpose like Server has been started, Incoming messages, outgoing messages etc in INFO level logging in java.

WARN is more restricted than INFO java logging level and used to log warning sort of messages e.g. Connection lost between client and server. Database connection lost, Socket reaching to its limit. These messages and java logging level are almost important because you can setup alert on these logging messages in java and let your support team monitor health of your java application and react on this warning messages. In Summary WARN level is used to log warning message for logging in Java.

ERROR is the more restricted java logging level than WARN and used to log Errors and Exception, you can also setup alert on this java logging level and alert monitoring team to react on this messages. ERROR is serious for logging in Java and you should always print it.

FATAL java logging level designates very severe error events that will presumably lead the application to abort. After this mostly your application crashes and stopped.

OFF java logging level has the highest possible rank and is intended to turn off logging in Java.

Generally it's easiest to use DESCRIBE.

DESCRIBE TABLE MYSCHEMA.TABLE

or

DESCRIBE INDEXES FOR MYSCHEMA.TABLE SHOW DETAIL

etc.

See the documentation: DESCRIBE command

Well,

Just worked it out. While having both installations we have two ORACLE_HOME directories and both have SQAORA32.dll files. While looking up for ORACLE_HOMe my app was getting confused..I just removed the Client oracle home entry as oracle client is by default present in oracle DB Now its working...Thanks!!
