Use $elemMatch to find the array of particular object

db.users.findOne({"_id": id},{awards: {$elemMatch: {award:'Turing Award', year:1977}}})

Collections.sort(testList);
Collections.reverse(testList);

That will do what you want. Remember to import Collections though!

Here is the documentation for Collections.

It's used to add padding in UIScrollView

Without contentInset, a table view is like this:

Then set contentInset:

tableView.contentInset = UIEdgeInsets(top: 20, left: 0, bottom: 0, right: 0)

The effect is as below:

Seems to be better, right?

And I write a blog to study the contentInset, criticism is welcome.

Using FormData is the way to go as indicated by many answers. here is a bit of code that works great for this purpose. I also agree with the comment of nesting ajax blocks to complete complex circumstances. By including e.PreventDefault(); in my experience makes the code more cross browser compatible.

    $('#UploadB1').click(function(e){        
    e.preventDefault();

    if (!fileupload.valid()) {
        return false;            
    }

    var myformData = new FormData();        
    myformData.append('file', $('#uploadFile')[0].files[0]);

    $("#UpdateMessage5").html("Uploading file ....");
    $("#UpdateMessage5").css("background","url(../include/images/loaderIcon.gif) no-repeat right");

    myformData.append('mode', 'fileUpload');
    myformData.append('myid', $('#myid').val());
    myformData.append('type', $('#fileType').val());
    //formData.append('myfile', file, file.name); 

    $.ajax({
        url: 'include/fetch.php',
        method: 'post',
        processData: false,
        contentType: false,
        cache: false,
        data: myformData,
        enctype: 'multipart/form-data',
        success: function(response){
            $("#UpdateMessage5").html(response); //.delay(2000).hide(1); 
            $("#UpdateMessage5").css("background","");

            console.log("file successfully submitted");
        },error: function(){
            console.log("not okay");
        }
    });
});

This uses the standard CSS border and a pseudo element+overflow:hidden. In the example you get three different 2px dashed borders: normal, spaced like a 5px, spaced like a 10px. Is actually 10px with only 10-8=2px visible.

div.two{border:2px dashed #FF0000}_x000D_

Applied to small elements with big rounded corners may make for some fun effects.

For Kotlin

What will you get:

Gray color if the hint is selected

Drop down list with gray color of the hint

Black color if something else than the hint is selected

I have added 5. step what changes the color of the text in the spinner depending on the selected item, because I couldn't find it here. In this case it is needed to change the text color to gray when the first item is selected in order to it looks like a hint.

1. Define a spinner in your activity_layout.xml

   <Spinner
       android:id="@+id/mySpinner"
       android:layout_width="match_parent"
       android:layout_height="wrap_content" />
   

2. Define the string array in string.xml where the first item will be a hint.

   <string-array name="your_string_array">
       <item>Hint...</item>
       <item>Item1</item>
       <item>Item2</item>
       <item>Item3</item>
   </string-array>
   

3. Set up the spinner in the onCreate method in your Activity.kt

   Get string array from resources

       val items= resources.getStringArray(R.array.your_string_array)
   

   Create spinner adapter

       val spinnerAdapter= object : ArrayAdapter<String>(this,android.R.layout.simple_spinner_item, items) {
   
       override fun isEnabled(position: Int): Boolean {
           // Disable the first item from Spinner
           // First item will be use for hint
           return position != 0
       }
   
       override fun getDropDownView(
           position: Int,
           convertView: View?,
           parent: ViewGroup
       ): View {
           val view: TextView = super.getDropDownView(position, convertView, parent) as TextView
           //set the color of first item in the drop down list to gray
           if(position == 0) {
               view.setTextColor(Color.GRAY)
           } else {
               //here is it possible to define color for other items by
               //view.setTextColor(Color.RED)
           }
           return view
       }
   
   }
   

4. Set drop down view resource and attach the adapter to your spinner.

   spinnerAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item)     
   mySpinner.adapter = spinnerAdapter
   

5. Change the color of the text in the spinner depending on the selected item

   mySpinner.onItemSelectedListener = object: AdapterView.OnItemSelectedListener{
       override fun onNothingSelected(parent: AdapterView<*>?) {
       }
   
       override fun onItemSelected(
           parent: AdapterView<*>?,
           view: View?,
           position: Int,
           id: Long
       ) {
           val value = parent!!.getItemAtPosition(position).toString()
           if(value == items[0]){
               (view as TextView).setTextColor(Color.GRAY)
           }
       }
   
   }
   

I was having the same problem and even though I was styling my button in CSS it would never pick up the border:none but what worked was adding a style directly on the input button like so:

<div style="text-align:center;">
    <input type="submit" class="SubmitButtonClass" style="border:none;" value="" />
</div>

Here's my answer for those that are Googling:

CSS:

.column {
    float: left;
    width: 50%;
}

/* Clear floats after the columns */
.container:after {
    content: "";
    display: table;
    clear: both;
}

Here's the HTML:

<div class="container">
    <div class="column"></div>
    <div class="column"></div>
</div>

Here is the explanation:

https://www.w3.org/TR/css-flexbox-1/#flex-common

flex: <positive-number>
Equivalent to flex: <positive-number> 1 0. Makes the flex item flexible and sets the flex basis to zero, resulting in an item that receives the specified proportion of the free space in the flex container. If all items in the flex container use this pattern, their sizes will be proportional to the specified flex factor.

Therefore flex:1 is equivalent to flex: 1 1 0

I catch all the exceptions and store it in database, so errors can be corrected easily - the page, place, date etc stored

try
{     
   Cart = DB.BuyOnlineCartMasters.Where(c => c.CmpyID == LoginID && c.Active == true).FirstOrDefault();
}
catch (Exception e)
{
    ErrorReport.StoreError("CartMinifiedPartial-Company", e);  
    -- storing the error for reference
}

Storing

public static void StoreError(string ErrorPage, Exception e)
    {
        try
        {
            eDurar.Models.db_edurarEntities1 DB = new Models.db_edurarEntities1();
            eDurar.Models.ErrorTable Err = new eDurar.Models.ErrorTable();
            Err.ErrorPage = ErrorPage;
            if (e.Message != null)
            {
                Err.ErrorDetails = e.Message;
            }
            if (e.InnerException != null)
            {
                Err.InnerException = e.InnerException.Message.ToString();
            }

            Err.Date = TimeZoneInfo.ConvertTimeFromUtc(DateTime.UtcNow, TimeZoneInfo.FindSystemTimeZoneById("India Standard Time"));
            DB.ErrorTables.AddObject(Err);
            DB.SaveChanges();
}

Be careful when using Logcat, it will truncate your message after ~4,076 bytes which can cause a lot of headache if you're printing out large amounts of data.

To get around this you have to write a function that will break it up into multiple parts like so.

window.onload however they are often the same thing. Similarly body.onload becomes window.onload in IE.

Whenever you do some form of operation outside of AngularJS, such as doing an Ajax call with jQuery, or binding an event to an element like you have here you need to let AngularJS know to update itself. Here is the code change you need to do:

app.directive("remove", function () {
    return function (scope, element, attrs) {
        element.bind ("mousedown", function () {
            scope.remove(element);
            scope.$apply();
        })
    };

});

app.directive("resize", function () {
    return function (scope, element, attrs) {
        element.bind ("mousedown", function () {
            scope.resize(element);
            scope.$apply();
        })
    };
});

Here is the documentation on it: https://docs.angularjs.org/api/ng/type/$rootScope.Scope#$apply

From stack trace:

HikariPool: Timeout failure pool HikariPool-0 stats (total=20, active=20, idle=0, waiting=0) Means pool reached maximum connections limit set in configuration.

The next line: HikariPool-0 - Connection is not available, request timed out after 30000ms. Means pool waited 30000ms for free connection but your application not returned any connection meanwhile.

Mostly it is connection leak (connection is not closed after borrowing from pool), set leakDetectionThreshold to the maximum value that you expect SQL query would take to execute.

otherwise, your maximum connections 'at a time' requirement is higher than 20 !

The Entity Framework should not cause major bottlenecks itself. Chances are that there are other causes. You could try to switch EF to Linq2SQL, both have comparing features and the code should be easy to convert but in many cases Linq2SQL is faster than EF.

The general format, from the @link section of the javadoc documentation, is:

Examples

Method in the same class:

/** See also {@link #myMethod(String)}. */
void foo() { ... }

Method in a different class, either in the same package or imported:

/** See also {@link MyOtherClass#myMethod(String)}. */
void foo() { ... }

Method in a different package and not imported:

/** See also {@link com.mypackage.YetAnotherClass#myMethod(String)}. */
void foo() { ... }

Label linked to method, in plain text rather than code font:

/** See also this {@linkplain #myMethod(String) implementation}. */
void foo() { ... }

A chain of method calls, as in your question. We have to specify labels for the links to methods outside this class, or we get getFoo().Foo.getBar().Bar.getBaz(). But these labels can be fragile during refactoring -- see "Labels" below.

/**
 * A convenience method, equivalent to 
 * {@link #getFoo()}.{@link Foo#getBar() getBar()}.{@link Bar#getBaz() getBaz()}.
 * @return baz
 */
public Baz fooBarBaz()

Labels

Automated refactoring may not affect labels. This includes renaming the method, class or package; and changing the method signature.

Therefore, provide a label only if you want different text than the default.

For example, you might link from human language to code:

/** You can also {@linkplain #getFoo() get the current foo}. */
void setFoo( Foo foo ) { ... }

Or you might link from a code sample with text different than the default, as shown above under "A chain of method calls." However, this can be fragile while APIs are evolving.

Type erasure and #member

If the method signature includes parameterized types, use the erasure of those types in the javadoc @link. For example:

int bar( Collection<Integer> receiver ) { ... }

/** See also {@link #bar(Collection)}. */
void foo() { ... }

I believe in order to have auto-wiring work on your MyLauncher class (for myService), you will need to let Spring initialize it instead of calling the constructor, by auto-wiring myLauncher. Once that is being auto-wired (and myService is also getting auto-wired), Spring (1.4.0 and up) provides a @MockBean annotation you can put in your test. This will replace a matching single beans in context with a mock of that type. You can then further define what mocking you want, in a @Before method.

public class MyLauncherTest
    @MockBean
    private MyService myService;

    @Autowired
    private MyLauncher myLauncher;

    @Before
    private void setupMockBean() {
        doNothing().when(myService).someVoidMethod();
        doReturn("Some Value").when(myService).someStringMethod();
    }

    @Test
    public void someTest() {
        myLauncher.doSomething();
    }
}

Your MyLauncher class can then remain unmodified, and your MyService bean will be a mock whose methods return values as you defined:

@Component
public class MyLauncher {
    @Autowired
    MyService myService;

    public void doSomething() {
        myService.someVoidMethod();
        myService.someMethodThatCallsSomeStringMethod();
    }

    //other methods
}

A couple advantages of this over other methods mentioned is that:

1. You don't need to manually inject myService.
2. You don't need use the Mockito runner or rules.

In addition, since info locals does not display the arguments to the function you're in, use

(gdb) info args

For example:

int main(int argc, char *argv[]) {
    argc = 6*7;    //Break here.
    return 0;
}

argc and argv won't be shown by info locals. The message will be "No locals."

Reference: info locals command.

If i understood correctly the easiest way is to use regular expression as it provides you lots of flexibility but the other simple method is to use for loop following is the code with example I also counted the occurrence of word and stored in dictionary..

s = """An... essay is, generally, a piece of writing that gives the author's own 
argument — but the definition is vague, 
overlapping with those of a paper, an article, a pamphlet, and a short story. Essays 
have traditionally been 
sub-classified as formal and informal. Formal essays are characterized by "serious 
purpose, dignity, logical 
organization, length," whereas the informal essay is characterized by "the personal 
element (self-revelation, 
individual tastes and experiences, confidential manner), humor, graceful style, 
rambling structure, unconventionality 
or novelty of theme," etc.[1]"""

d = {}      # creating empty dic      
words = s.split() # spliting string and stroing in list
for word in words:
    new_word = ''
    for c in word:
        if c.isalnum(): # checking if indiviual chr is alphanumeric or not
            new_word = new_word + c
    print(new_word, end=' ')
    # if new_word not in d:
    #     d[new_word] = 1
    # else:
    #     d[new_word] = d[new_word] +1
print(d)

please rate this if this answer is useful!

one solution could be to find a way of pulling the numbers from the string and placing them in a column of just numbers the using the =MEDIAN() function giving the new number column as the range

It looks like the best approach is to use:

ContextCompat.getColor(context, R.color.color_name)

eg:

yourView.setBackgroundColor(ContextCompat.getColor(applicationContext,
                            R.color.colorAccent))

This will choose the Marshmallow two parameter method or the pre-Marshmallow method appropriately.

In case you are using node.js (with express)

If you want to serve static files in node.js, you need to use a function. Add the following code to your js file:

app.use(express.static("public"));

Where app is:

const express = require("express");
const app = express();

Then create a folder called public in you project folder. (You could call it something else, this is just good practice but remember to change it from the function as well.)

Then in this file create another folder named css (and/or images file under css if you want to serve static images as well.) then add your css files to this folder.

After you add them change the stylesheet accordingly. For example if it was:

href="cssFileName.css"

and

src="imgName.png"

Make them:

href="css/cssFileName.css"
src="css/images/imgName.png"

That should work

I needed to exclude an auditing @Aspect @Component from the app context but only for a few test classes. I ended up using @Profile("audit") on the aspect class; including the profile for normal operations but excluding it (don't put it in @ActiveProfiles) on the specific test classes.

"-TotalCount" in this instance responds exactly like "-head". You have to use -TotalCount or -head to run the command like that. But -TotalCount is misleading - it does not work in ACTUALLY giving you ANY counts...

gc -TotalCount 25 C:\scripts\logs\robocopy_report.txt

The above script, tested in PS 5.1 is the SAME response as below...

gc -head 25 C:\scripts\logs\robocopy_report.txt

So then just use '-head 25" already!

For Microsoft Azure, it's slightly different.

Azure has a special CORS setting that needs to be set. It's essentially the same thing behind the scenes, but simply setting the header joshuarh mentions will not work. The Azure documentation for enabling cross domain can be found here:

https://docs.microsoft.com/en-us/azure/app-service-api/app-service-api-cors-consume-javascript

I fiddled around with this for a few hours before realizing my hosting platform had this special setting.

<html>

<head>
<script type="text/javascript">
function insertText () {
    document.getElementById('td1').innerHTML = "Some text to enter";
}
</script>
</head>

<body onload="insertText();">
    <table>
        <tr>
            <td id="td1"></td>
        </tr>
    </table>
</body>
</html>

Nowadays (2016) in Chrome Dev Tools console, you can quickly execute this function below to show all event listeners that have been attached to an element.

getEventListeners(document.querySelector('your-element-selector'));

You can set the value property using client script after the element is created:

<input type="text" id="fee" />

<script type="text/javascript>
document.getElementById('fee').value = '1000';
</script>

As above the question was originally about MySQL

Use REGEXP, not LIKE:

SELECT * FROM `table` WHERE ([url] NOT REGEXP '^[-A-Za-z0-9/.]+$')

$res = explode("\n",wordwrap('12345678910', 8, "...\n",true))[0];

// $res will be  : "12345678..."

The only information currently available is that Apple Pay will be available in ios8, but that doesn't shed any light on whether RFID tags or rather NFC tags specifically will be able to be detected/read.

IMO it would be a shortsighted move not to allow that possibility, but really the money is in Apple Pay, not necessarily in allowing developers access to those features - we've seen it before with tethering, Bluetooth SPP, and diminished access to certain functions.

...but then again, it's been about 5 hours since the first announcement.

private int totalHeight = 0;

ViewTreeObserver ScrollTr = loutMain.getViewTreeObserver();
ScrollTr.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
    @Override
    public void onGlobalLayout() {
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN) {
            loutMain.getViewTreeObserver().removeGlobalOnLayoutListener(this);
        } else {
            loutMain.getViewTreeObserver().removeOnGlobalLayoutListener(this);
        }
        TotalHeight = loutMain.getMeasuredHeight();

    }
});

scrollMain.smoothScrollTo(0, totalHeight);

Just a followup to smashery's answer. The ephemeral port range (on Linux at least, and I suspect other Unices as well) is not a fixed. This can be controlled by writing to /proc/sys/net/ipv4/ip_local_port_range

The only restriction (as far as IANA is concerned) is that ports below 1024 are designated to be well-known ports. Ports above that are free for use. Often you'll find that ports below 1024 are restricted to superuser access, I believe for this very reason.

I may be wrong about this.. but anyways, I think POCO is Plain Old Class CLR Object and it comes from POJO plain old Java Object. A POCO is a class that holds data and has no behaviours.

Here is an example written in C#:

class Fruit 
{
    public Fruit() { }

    public Fruit(string name, double weight, int quantity) 
    {
        Name = name;
        Weight = weight;
        Quantity = quantity;
    }

    public string Name { get; set; }
    public double Weight { get; set; }
    public int Quantity { get; set; }

    public override string ToString() 
    {
        return $"{Name.ToUpper()} ({Weight}oz): {Quantity}";
    }
}

The accepted answer does not work for databases that have large numbers of tables, e.g. Drupal databases. Instead, see the script here: https://stackoverflow.com/a/12917793/1507877 which does work on MySQL 5.5. CAUTION: Around line 11, there is a "WHERE table_schema = SCHEMA();" This should instead be "WHERE table_schema = 'INSERT NAME OF DB INTO WHICH IMPORT WILL OCCUR';"

UTF-8 works for me with Polish characters

format(99999999,scientific = F)

gives

99999999

Create a new folder and run git init in it.

Then try git remote add origin <your-repository-url>.

Copy all the files in your project folder to the new folder, except the .git folder (it may be invisible).

Then you can push your code by doing:
git add --all; or git add -A;
git commit -m "YOUR MESSAGE";
git push -u origin master.

I think it will work!

[Update]

More recently, there is Amazon AWS ECR (Elastic Container Registry), which provides a Docker image registry to which you can control access by means of the AWS IAM access management service. ECR can also run a CVE (vulnerabilities) check on your image when you push it.

Once you create your ECR, and obtain the "URL" you can push and pull as required, subject to the permissions you create: hence making it private or public as you wish.

Pricing is by amount of data stored, and data transfer costs.

[Original answer]

If you do not want to use the Docker Hub itself, you can host your own Docker repository under Artifactory by JFrog:

https://www.jfrog.com/confluence/display/RTF/Docker+Repositories

which will then run on your own server(s).

Other hosting suppliers are available, eg CoreOS:

which bought quay.io

This is Euclid Algorithm.

e.g

a mod b = k * b + c => a mod b = c, where k is an integer and c is the answer

4 mod 2 = 2 * 2 + 0 => 4 mod 2 = 0

27 mod 5 = 5 * 5 + 2 => 27 mod 5 = 2

so your answer is

2 mod 4 = 0 * 4 + 2 => 2 mod 4 = 2

You could really, really, really optimize your code a lot by paying the price of creating the delegate only once (there's also no need to instantiate the class to call an static method). I've done something very similar, and I just cache a delegate to the "Run" method with the help of a helper class :-). It looks like this:

static class Indent{    
     public static void Run(){
         // implementation
     }
     // other helper methods
}

static class MacroRunner {

    static MacroRunner() {
        BuildMacroRunnerList();
    }

    static void BuildMacroRunnerList() {
        macroRunners = System.Reflection.Assembly.GetExecutingAssembly()
            .GetTypes()
            .Where(x => x.Namespace.ToUpper().Contains("MACRO"))
            .Select(t => (Action)Delegate.CreateDelegate(
                typeof(Action), 
                null, 
                t.GetMethod("Run", System.Reflection.BindingFlags.Static | System.Reflection.BindingFlags.Public)))
            .ToList();
    }

    static List<Action> macroRunners;

    public static void Run() {
        foreach(var run in macroRunners)
            run();
    }
}

It is MUCH faster this way.

If your method signature is different from Action you could replace the type-casts and typeof from Action to any of the needed Action and Func generic types, or declare your Delegate and use it. My own implementation uses Func to pretty print objects:

static class PrettyPrinter {

    static PrettyPrinter() {
        BuildPrettyPrinterList();
    }

    static void BuildPrettyPrinterList() {
        printers = System.Reflection.Assembly.GetExecutingAssembly()
            .GetTypes()
            .Where(x => x.Name.EndsWith("PrettyPrinter"))
            .Select(t => (Func<object, string>)Delegate.CreateDelegate(
                typeof(Func<object, string>), 
                null, 
                t.GetMethod("Print", System.Reflection.BindingFlags.Static | System.Reflection.BindingFlags.Public)))
            .ToList();
    }

    static List<Func<object, string>> printers;

    public static void Print(object obj) {
        foreach(var printer in printers)
            print(obj);
    }
}

Use split and map function:

var str = "123, 124, 234,252";
var arr = str.split(",");
arr = arr.map(function (val) { return +val + 1; });

Notice +val - string is casted to a number.

Or shorter:

var str = "123, 124, 234,252";
var arr = str.split(",").map(function (val) { return +val + 1; });

edit 2015.07.29

Today I'd advise against using + operator to cast variable to a number. Instead I'd go with a more explicit but also more readable Number call:

var str = "123, 124, 234,252";_x000D_
var arr = str.split(",").map(function (val) {_x000D_
  return Number(val) + 1;_x000D_
});_x000D_
console.log(arr);

edit 2017.03.09

ECMAScript 2015 introduced arrow function so it could be used instead to make the code more concise:

var str = "123, 124, 234,252";_x000D_
var arr = str.split(",").map(val => Number(val) + 1);_x000D_
console.log(arr);

Easiest way is probably to convert from a VARCHAR to a DATE; then format it back to a VARCHAR again in the format you want;

SELECT TO_CHAR(TO_DATE(DOJ,'MM/DD/YYYY'), 'MM/DD/YYYY') FROM EmpTable;

An SQLfiddle to test with.

To help with this I created a function to make this more easy to achieve it.

public static <T> void forEachCurrent(List<T> list, Consumer<T> action) {
    final int size = list.size();
    for (int i = 0; i < size; i++) {
        action.accept(list.get(i));
    }
}

Example

    List<String> l = new ArrayList<>();
    l.add("1");
    l.add("2");
    l.add("3");
    forEachCurrent(l, e -> {
        l.add(e + "A");
        l.add(e + "B");
        l.add(e + "C");
    });
    l.forEach(System.out::println);

Package version are very important.

Implement the routerOnActivate in your @Component and return your promise:

Using the LOAD DATA INFILE SQL statement you can import the CSV file, but you can't update data. However, there is a trick you can use.

• Create another temporary table to use for the import

• Load onto this table from the CSC

  LOAD DATA LOCAL INFILE '/file.csv'
  INTO TABLE temp_table
  FIELDS TERMINATED BY ','
  LINES TERMINATED BY '\n'
  (field1, field2, field3); 
  

• UPDATE the real table joining the table

  UPDATE maintable
  INNER JOIN temp_table A USING (field1)
  SET maintable.field1 = temp_table.field1
  

For those looking for a dynamic solution to embed Matplotlib in PyQt5 (even plot data using drag and drop). In PyQt5 you need to use super on the main window class to accept the drops. The dropevent function can be used to get the filename and rest is simple:

def dropEvent(self,e):
        """
        This function will enable the drop file directly on to the 
        main window. The file location will be stored in the self.filename
        """
        if e.mimeData().hasUrls:
            e.setDropAction(QtCore.Qt.CopyAction)
            e.accept()
            for url in e.mimeData().urls():
                if op_sys == 'Darwin':
                    fname = str(NSURL.URLWithString_(str(url.toString())).filePathURL().path())
                else:
                    fname = str(url.toLocalFile())
            self.filename = fname
            print("GOT ADDRESS:",self.filename)
            self.readData()
        else:
            e.ignore() # just like above functions  

For starters the reference complete code gives this output:

For those running in such issues right now, just try to put an alias for the table, this should the trick, e.g:

SELECT myvalue 
  INTO myvar 
  FROM mytable x
 WHERE x.anothervalue = 1;

It worked for me.

Cheers.

Polymorphism is the ability to treat a class of object as if it is the parent class.

For instance, suppose there is a class called Animal, and a class called Dog that inherits from Animal. Polymorphism is the ability to treat any Dog object as an Animal object like so:

Dog* dog = new Dog;
Animal* animal = dog;

As I stated in comment i would use a box layout for this.

JPanel panel = new JPanel();
panel.setLayout(new BoxLayout());

JButton button = new JButton("Button1");
button.setAlignmentX(Component.CENTER_ALIGNMENT);
panel.add(button);

button = new JButton("Button2");
button.setAlignmentX(Component.CENTER_ALIGNMENT);
panel.add(button);

button = new JButton("Button3");
button.setAlignmentX(Component.CENTER_ALIGNMENT);
panel.add(button);

add(panel);

To solve, you need to import Private Certificate (PFX).

If you don't have PFX, use OpenSSL to generate it:

• Download&Install OpenSSL

• Open command line and run:

  openssl pkcs12 -export -in public_certificate.cer -inkey server.key -out private_certificate.pfx

Than, install private_certificate.pfx (right click -> Install Certificate).

Now, your certificate does not disappear anymore and you can bind Website over SSL.

A great resource: https://blog.lextudio.com/the-whole-story-of-server-certificate-disappears-in-iis-7-7-5-8-8-5-10-0-after-installing-it-why-b66e802baa38

I'd prefer this way to redirect standard output (native PowerShell)...

($foo = someFunction) | out-null

But this works too:

($foo = someFunction) > $null

To redirect just standard error after defining $foo with result of "someFunction", do

($foo = someFunction) 2> $null

This is effectively the same as mentioned above.

Or to redirect any standard error messages from "someFunction" and then defining $foo with the result:

$foo = (someFunction 2> $null)

To redirect both you have a few options:

2>&1>$null
2>&1 | out-null

In my case elasticsearch was started. But still had

curl: (7) Failed to connect to localhost port 9200: Connection refused

The following command was unsuccessful

sudo service elasticsearch restart

In order to make it work, I had to run instead

sudo systemctl restart elasticsearch

Then it went all fine.

Very, very, very simple Enum with string (TypeScript 2.4)

        let message = ""
        switch (id) {
            case MESSAGES.ERROR_CHART_UNKNOWN :
                message = "The chart does not exist."
                break;
            case MESSAGES.ERROR_2 :
                message = "example."
                break;
        }
        return message
    }
}

function log(messageName:MESSAGES){
    console.log(Messages.get(messageName))
}

first: just use add method instead of replace method of FragmentTransaction class then you have to add secondFragment to stack by addToBackStack method

second :on back click you have to call popBackStackImmediate()

Fragment sourceFragment = new SourceFragment ();
final Fragment secondFragment = new SecondFragment();
final FragmentTransaction ft = getChildFragmentManager().beginTransaction();
ft.add(R.id.child_fragment_container, secondFragment );
ft.hide(sourceFragment );
ft.addToBackStack(NewsShow.class.getName());
ft.commit();
                                
((SecondFragment)secondFragment).backFragmentInstanceClick = new SecondFragment.backFragmentNewsResult()
{
        @Override
        public void backFragmentNewsResult()
        {                                    
            getChildFragmentManager().popBackStackImmediate();                                
        }
};

GoalSeek will throw an "Invalid Reference" error if the GoalSeek cell contains a value rather than a formula or if the ChangingCell contains a formula instead of a value or nothing.

The GoalSeek cell must contain a formula that refers directly or indirectly to the ChangingCell; if the formula doesn't refer to the ChangingCell in some way, GoalSeek either may not converge to an answer or may produce a nonsensical answer.

I tested your code with a different GoalSeek formula than yours (I wasn't quite clear whether some of the terms referred to cells or values).

For the test, I set:

  the GoalSeek cell  H18 = (G18^3)+(3*G18^2)+6
  the Goal cell      H32 =  11
  the ChangingCell   G18 =  0 

The code was:

Sub GSeek()
    With Worksheets("Sheet1")
        .Range("H18").GoalSeek _
        Goal:=.Range("H32").Value, _
        ChangingCell:=.Range("G18")
    End With
End Sub

And the code produced the (correct) answer of 1.1038, the value of G18 at which the formula in H18 produces the value of 11, the goal I was seeking.

Try out the CImg library. The tutorial will help you get familiarized. Once you have a CImg object, the data() function will give you access to the 2D pixel buffer array.

You can do this by 2 options:

Option 1: By setting its xml attributes

 `android:textOff="TEXT OFF"
  android:textOn="TEXT ON"`

Option 2: Programmatically

Set the attribute onClick: methodNameHere (mine is toggleState) Then write this code:

public void toggleState(View view) {
   boolean toggle = ((ToogleButton)view).isChecked();
   if (toggle){
       ((ToogleButton)view).setTextOn("TEXT ON");
   } else {
      ((ToogleButton)view).setTextOff("TEXT OFF");
   }
}

PS: it works for me, hope it works for you too

Thread

The bare metal thing, you probably don't need to use it, you probably can use a LongRunning task and take the benefits from the TPL - Task Parallel Library, included in .NET Framework 4 (february, 2002) and above (also .NET Core).

Tasks

Abstraction above the Threads. It uses the thread pool (unless you specify the task as a LongRunning operation, if so, a new thread is created under the hood for you).

Thread Pool

As the name suggests: a pool of threads. Is the .NET framework handling a limited number of threads for you. Why? Because opening 100 threads to execute expensive CPU operations on a Processor with just 8 cores definitely is not a good idea. The framework will maintain this pool for you, reusing the threads (not creating/killing them at each operation), and executing some of them in parallel, in a way that your CPU will not burn.

OK, but when to use each one?

In resume: always use tasks.

Task is an abstraction, so it is a lot easier to use. I advise you to always try to use tasks and if you face some problem that makes you need to handle a thread by yourself (probably 1% of the time) then use threads.

BUT be aware that:

• I/O Bound: For I/O bound operations (database calls, read/write files, APIs calls, etc) avoid using normal tasks, use LongRunning tasks (or threads if you need to). Because using tasks would lead you to a thread pool with a few threads busy and a lot of another tasks waiting for its turn to take the pool.
• CPU Bound: For CPU bound operations just use the normal tasks (that internally will use the thread pool) and be happy.

SASS modules version

Soon, using @import in sass will be depreciated. SASS modules configuration works using @use instead.

@use "../node_modules/font-awesome/scss/font-awesome"  with (
  $fa-font-path: "../icons"
);

.icon-user {
  @extend .fa;
  @extend .fa-user;

Original Answer: Resetting a multi-stage form with jQuery

Mike's suggestion (from the comments) to keep checkbox and selects intact!

Warning: If you're creating elements (so they're not in the dom), replace :hidden with [type=hidden] or all fields will be ignored!

$(':input','#myform')
  .removeAttr('checked')
  .removeAttr('selected')
  .not(':button, :submit, :reset, :hidden, :radio, :checkbox')
  .val('');

SHOW TABLES

SHOW TABLES FROM mydatabase

SHOW TABLES FROM mydatabase LIKE "tab%"

to

extension=php_imap.dll

I wrote an App that runs a WebServer (REST-Like) on your Android Phone, so you can set the GPS position remotely. The website provides an Map on which you can click to set a new position, or use the "wasd" keys to move in any direction. The app was a quick solution so there is nearly no UI nor Documentation, but the implementation is straight forward and you can look everything up in the (only four) classes.

In 2020, using duckduckgo.com's service from the CLI

Example

curl -v https://icons.duckduckgo.com/ip2/www.cdc.gov.ico > favicon.ico

The Path class is very useful here.
You get two methods called

Path.GetTempFileName

Path.GetTempPath

that could solve your issue

So for example you could write: (if you don't mind the exact file name)

using(StreamWriter sw = new StreamWriter(Path.GetTempFileName()))
{
    sw.WriteLine("Your error message");
}

Or if you need to set your file name

string myTempFile = Path.Combine(Path.GetTempPath(), "SaveFile.txt");
using(StreamWriter sw = new StreamWriter(myTempFile))
{
     sw.WriteLine("Your error message");
}

Try this (Note: I don't have right now Visual Studio ,so code is copy paste from my archive(I haven't test it) :

    Dim drv As DataRowView
    If e.RowIndex >= 0 Then
        If e.RowIndex <= ds.Tables("Products").Rows.Count - 1 Then
            drv = ds.Tables("Products").DefaultView.Item(e.RowIndex)
            Dim c As Color
            If drv.Item("Quantity").Value < 5  Then
                c = Color.LightBlue
            Else
                c = Color.Pink
            End If
            e.CellStyle.BackColor = c

The expression df1$id %in% idNums1 produces a logical vector. To negate it, you need to negate the whole vector:

!(df1$id %in% idNums1)

You can embed all dlls in you main dll. See: Embedding DLLs in a compiled executable

depending on how many columns there are, you could just name the columns, sans the ID, and manually add an ID or, if it's in your table, a secondary ID (sid):

insert into PROG(date, level, Percent, sid) select date, level, Percent, 55 from PROG where sid = 31 Here, if sid 31 has more than one resultant row, all of them will be copied over to sid 55 and your auto iDs will still get auto-generated. for ID only: insert into PROG(date, level, Percent, ID) select date, level, Percent, 55 from PROG where ID = 31 where 55 is the next available ID in the table and ID 31 is the one you want to copy.

While I agree it's not good style to catch a raw Exception, there are ways of handling exceptions which provide for superior logging, and the ability to handle the unexpected. Since you are in an exceptional state, you are probably more interested in getting good information than in response time, so instanceof performance shouldn't be a big hit.

try{
    // IO code
} catch (Exception e){
    if(e instanceof IOException){
        // handle this exception type
    } else if (e instanceof AnotherExceptionType){
        //handle this one
    } else {
        // We didn't expect this one. What could it be? Let's log it, and let it bubble up the hierarchy.
        throw e;
    }
}

However, this doesn't take into consideration the fact that IO can also throw Errors. Errors are not Exceptions. Errors are a under a different inheritance hierarchy than Exceptions, though both share the base class Throwable. Since IO can throw Errors, you may want to go so far as to catch Throwable

try{
    // IO code
} catch (Throwable t){
    if(t instanceof Exception){
        if(t instanceof IOException){
            // handle this exception type
        } else if (t instanceof AnotherExceptionType){
            //handle this one
        } else {
            // We didn't expect this Exception. What could it be? Let's log it, and let it bubble up the hierarchy.
        }
    } else if (t instanceof Error){
        if(t instanceof IOError){
            // handle this Error
        } else if (t instanceof AnotherError){
            //handle different Error
        } else {
            // We didn't expect this Error. What could it be? Let's log it, and let it bubble up the hierarchy.
        }
    } else {
        // This should never be reached, unless you have subclassed Throwable for your own purposes.
        throw t;
    }
}

Here is a quick solution using find and also sorting files by their modification date:

$ find  directory/ -maxdepth 1 -type f -print0 | \
  xargs -r0 stat -c "%y %n" | \
  sort | cut -d' ' -f4- | \
  xargs -d "\n" -I{} cmd -op1 {} 

For sorting see:

I have started using Markdown to post some of my documents to an internal web site for in-house users. It is an easy way to have a document shared but not able to be edited by the viewer.

So, this marking of text in color is “Great”. I have use several like this and works wonderful.

<span style="color:blue">some *This is Blue italic.* text</span>

Turns into This is Blue italic.

And

<span style="color:red">some **This is Red Bold.** text</span>

Turns into This is Red Bold.

I love the flexibility and ease of use.

You have two possibilities:

1. non-static setter for static property/field;
2. using org.springframework.beans.factory.config.MethodInvokingFactoryBean to invoke a static setter.

In the first option you have a bean with a regular setter but instead setting an instance property you set the static property/field.

public void setTheProperty(Object value) {
    foo.bar.Class.STATIC_VALUE = value;
}

but in order to do this you need to have an instance of a bean that will expose this setter (its more like an workaround).

In the second case it would be done as follows:

<bean class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
    <property name="staticMethod" value="foo.bar.Class.setTheProperty"/>
    <property name="arguments">
        <list>
            <ref bean="theProperty"/>
        </list>
   </property>
</bean>

On you case you will add a new setter on the Utils class:

public static setDataBaseAttr(Properties p)

and in your context you will configure it with the approach exemplified above, more or less like:

<bean class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
    <property name="staticMethod" value="foo.bar.Utils.setDataBaseAttr"/>
    <property name="arguments">
        <list>
            <ref bean="dataBaseAttr"/>
        </list>
   </property>
</bean>

I'm not sure of the details as you haven't posted the whole code, but:

• remember to override hashCode() as well
• the equals method should have Object, not People as its argument type. At the moment you are overloading, not overriding, the equals method, which probably isn't what you want, especially given that you check its type later.
• you can use instanceof to check it is a People object e.g. if (!(other instanceof People)) { result = false;}
• equals is used for all objects, but not primitives. I think you mean age is an int (primitive), in which case just use ==. Note that an Integer (with a capital 'I') is an Object which should be compared with equals.

See What issues should be considered when overriding equals and hashCode in Java? for more details.

For those who came here looking for the answer and didnt type 3306 wrong...If like myself, you have wasted hours with no luck searching for this answer, then possibly this may help.

If you are seeing this: (HY000/2002): No connection could be made because the target machine actively refused it

Then my understanding is that it cant connect for one of the following below. Now which..

1) is your wamp, mamp, etc icon GREEN? Either way, right-click the icon --> click tools --> test both the port used for Apache (typically 80) and for Mariadb (3307?). Should say 'It is correct' for both.

2) Error comes from a .php file. So, check your dbconnect.php.

<?php
$servername = "localhost";
$username = "your_username";
$password = "your_pw";
$dbname = "your_dbname";
$port = "3307";
?>

Is your setup correct? Does your user exist? Do they have rights? Does port match the tested port in 1)? Doesn't have to be 3307 and user can be root. You can also left click the green icon --> click MariaDB and view used port as shown in the image below. All good? Positive? ok!

3) Error comes when you login to phpmyadmin. So, check your my.ini.

Open my.ini by left clicking the green icon --> click MariaDB -->

; The following options will be passed to all MariaDB clients
[client]
;password = your_password
port = 3307
socket = /tmp/mariadb.sock

; Here follows entries for some specific programs

; The MariaDB server
[wampmariadb64]
;skip-grant-tables
port = 3307
socket = /tmp/mariadb.sock

Make sure the ports match the port MariaDB is being testing on. Then finally..

[mysqld]
port = 3307

At the bottom of my.ini, make sure this port matches as well.

4) 1-3 done? restart your WAMP and cross your fingers!

What about something like this (might have rounding errors and negative-value issues that need debugging, left as an exercise for the reader):

printf("%.0d%.4g\n", (int)f/10, f-((int)f-(int)f%10));

It's slightly programmatic but at least it doesn't make you do any string manipulation.

Here is another version. If your Scenario requires Saturday to be 1st day of Week and Friday to be last day of Week, the below code will handle that:

  DECLARE @myDate DATE = GETDATE()
  SELECT    @myDate,
    DATENAME(WEEKDAY,@myDate),
    DATEADD(DD,-(CHOOSE(DATEPART(dw, @myDate), 1,2,3,4,5,6,0)),@myDate) AS WeekStartDate,
    DATEADD(DD,7-CHOOSE(DATEPART(dw, @myDate), 2,3,4,5,6,7,1),@myDate) AS WeekEndDate

You need to create new Book objects then put those in a new List:

List<Book> books_2 = books_1.Select(book => new Book(book.title)).ToList();

Update: Slightly simpler... List<T> has a method called ConvertAll that returns a new list:

List<Book> books_2 = books_1.ConvertAll(book => new Book(book.title));

I would opt for NOT EXISTS in this case.

SELECT D1.ShortCode
FROM Domain1 D1
WHERE NOT EXISTS
    (SELECT 'X'
     FROM Domain2 D2
     WHERE D2.ShortCode = D1.ShortCode
    )

For the relative path (i.e. the direct equivalent of Windows' %~dp0):

MY_PATH="`dirname \"$0\"`"
echo "$MY_PATH"

For the absolute, normalized path:

MY_PATH="`dirname \"$0\"`"              # relative
MY_PATH="`( cd \"$MY_PATH\" && pwd )`"  # absolutized and normalized
if [ -z "$MY_PATH" ] ; then
  # error; for some reason, the path is not accessible
  # to the script (e.g. permissions re-evaled after suid)
  exit 1  # fail
fi
echo "$MY_PATH"

I like @jesterjunk answer, however, a number is not always just digits. Consider those valid numbers: "123.5, 123,567.789, 12233234+E12"

So I just updated the regular expression:

var regex = /[\d|,|.|e|E|\+]+/g;

var string = "you can enter maximum 5,123.6 choices";
var matches = string.match(regex);  // creates array from matches

document.write(matches); //5,123.6

You can use is_uploaded_file():

if(!file_exists($_FILES['myfile']['tmp_name']) || !is_uploaded_file($_FILES['myfile']['tmp_name'])) {
    echo 'No upload';
}

From the docs:

Returns TRUE if the file named by filename was uploaded via HTTP POST. This is useful to help ensure that a malicious user hasn't tried to trick the script into working on files upon which it should not be working--for instance, /etc/passwd.

This sort of check is especially important if there is any chance that anything done with uploaded files could reveal their contents to the user, or even to other users on the same system.

EDIT: I'm using this in my FileUpload class, in case it helps:

public function fileUploaded()
{
    if(empty($_FILES)) {
        return false;       
    } 
    $this->file = $_FILES[$this->formField];
    if(!file_exists($this->file['tmp_name']) || !is_uploaded_file($this->file['tmp_name'])){
        $this->errors['FileNotExists'] = true;
        return false;
    }   
    return true;
}

This should be quite fast

function splitOnFirst (str, sep) {
  const index = str.indexOf(sep);
  return index < 0 ? [str] : [str.slice(0, index), str.slice(index + sep.length)];
}

You can simply press Ctrl+F5 instead of F5 to run the built code. Then it will prompt you to press any key to continue. Or you can use this line -> system("pause"); at the end of the code to make it wait until you press any key.

However, if you use the above line, system("pause"); and press Ctrl+F5 to run, it will prompt you twice!

With a simple JSON object, you don't need jQuery:

for (var i in json) {
   for (var j in json[i]) {
     console.log(json[i][j]);
   }
}

A simple way of keeping the values of fields in different fragments in an activity

Create the Instances of fragments and add instead of replace and remove

    FragA  fa= new FragA();
    FragB  fb= new FragB();
    FragC  fc= new FragB();
    fragmentManager = getSupportFragmentManager();
    fragmentTransaction = fragmentManager.beginTransaction();
    fragmentTransaction.add(R.id.fragmnt_container, fa);
    fragmentTransaction.add(R.id.fragmnt_container, fb);
    fragmentTransaction.add(R.id.fragmnt_container, fc);
    fragmentTransaction.show(fa);
    fragmentTransaction.hide(fb);
    fragmentTransaction.hide(fc);
    fragmentTransaction.commit();

Then just show and hide the fragments instead of adding and removing those again

    fragmentTransaction = fragmentManager.beginTransaction();
    fragmentTransaction.hide(fa);
    fragmentTransaction.show(fb);
    fragmentTransaction.hide(fc);
    fragmentTransaction.commit()

;

Unlike the other answers that use a formatter, you can also just add an "0" text in front of each number inside of the loop, like this:

for myInt in 1...3 {
    println("0" + "\(myInt)")
}

But formatter is often better when you have to add suppose a designated amount of 0s for each seperate number. If you only need to add one 0, though, then it's really just your pick.

Actually that is not 100% correct. That can give you Model (sometime numbers).
Will get you the Manufacturer of the phone (HTC portion of your request):

 Build.MANUFACTURER

For a product name:

 Build.PRODUCT

This will match yyyy-mm-dd and also yyyy-m-d:

^\d{4}\-(0?[1-9]|1[012])\-(0?[1-9]|[12][0-9]|3[01])$

If you're looking for an exact match for yyyy-mm-dd then try this

^\d{4}\-(0[1-9]|1[012])\-(0[1-9]|[12][0-9]|3[01])$

or use this one if you need to find a date inside a string like The date is 2017-11-30

\d{4}\-(0?[1-9]|1[012])\-(0?[1-9]|[12][0-9]|3[01])*

WSDL (Web Services Description Language) describes your service and its operations - what is the service called, which methods does it offer, what kind of in parameters and return values do these methods have?

It's a description of the behavior of the service - it's functionality.

XSD (Xml Schema Definition) describes the static structure of the complex data types being exchanged by those service methods. It describes the types, their fields, any restriction on those fields (like max length or a regex pattern) and so forth.

It's a description of datatypes and thus static properties of the service - it's about data.

You can use cin.get(); or cin.ignore(); just before your return statement to avoid the console window from closing.

Doing it the mathy way...

nums = [1, 2, 3, 4, 5]
min_combo = (min(nums), max(nums))

Unless, of course, you have negatives in there. In that case, this won't work because you actually want the min and max absolute values - the numerator should be close to zero, and the denominator far from it, in either direction. And double negatives would break it.

Error 127 means one of two things:

1. file not found: the path you're using is incorrect. double check that the program is actually in your $PATH, or in this case, the relative path is correct -- remember that the current working directory for a random terminal might not be the same for the IDE you're using. it might be better to just use an absolute path instead.
2. ldso is not found: you're using a pre-compiled binary and it wants an interpreter that isn't on your system. maybe you're using an x86_64 (64-bit) distro, but the prebuilt is for x86 (32-bit). you can determine whether this is the answer by opening a terminal and attempting to execute it directly. or by running file -L on /bin/sh (to get your default/native format) and on the compiler itself (to see what format it is).

if the problem is (2), then you can solve it in a few diff ways:

1. get a better binary. talk to the vendor that gave you the toolchain and ask them for one that doesn't suck.
2. see if your distro can install the multilib set of files. most x86_64 64-bit distros allow you to install x86 32-bit libraries in parallel.
3. build your own cross-compiler using something like crosstool-ng.
4. you could switch between an x86_64 & x86 install, but that seems a bit drastic ;).

for (var i in a) {
   console.log(a[i],i)
}

Every one has written an answer but I am still surprised that nobody actually answered it by using the best simple way.
The people answer that include the jar file. But, the error will still occur.

The reason for that is, the jar is not deployed when the project is run. So, what we need to do is, tell the IDE to deploy this jar also.

The people here has answered so many times that put that jar file in the lib folder of WEB-INF. That seems okay, but why do it manually. There is simple way. Check the below steps:

Step 1: If you haven't referenced the jar file into the project then, reference it like this.

Right click on the project and go to the project properties. Then, go to the java build path, then add external jar file via that.

But this will still not solve the problem because adding the external jar via build path only helps in compiling the classes, and the jar will not be deployed when you run the project. For that follow this step

Right click on the project and go to the project properties. Then, go to the Deployment Assembly then press Add , then go to the java build path entries and add your libraries whether it is jstl, mysql or any other jar file. add them to deployment. Below are the two pictures which display it.

This one works on Bootstrap 4.3.1.

I had the same issue. And the files that I needed to be committed were never declared in the .gitignore file as well.

In my case adding the files forcefully using the -f flag elevated to staging and fixed the issue.

git add -f <path to file>

Not dplyr, but it's much more direct using data.table:

library(data.table)
setDT(df)
df[ df[order(id, stopSequence), .I[c(1L,.N)], by=id]$V1 ]
#    id stopId stopSequence
# 1:  1      a            1
# 2:  1      c            3
# 3:  2      b            1
# 4:  2      c            4
# 5:  3      b            1
# 6:  3      a            3

More detailed explanation:

# 1) get row numbers of first/last observations from each group
#    * basically, we sort the table by id/stopSequence, then,
#      grouping by id, name the row numbers of the first/last
#      observations for each id; since this operation produces
#      a data.table
#    * .I is data.table shorthand for the row number
#    * here, to be maximally explicit, I've named the variable V1
#      as row_num to give other readers of my code a clearer
#      understanding of what operation is producing what variable
first_last = df[order(id, stopSequence), .(row_num = .I[c(1L,.N)]), by=id]
idx = first_last$row_num

# 2) extract rows by number
df[idx]

Be sure to check out the Getting Started wiki for getting the data.table basics covered

This method I've used a lot, not sure if it is a very good way but it works fine for my needs.

• You don't need constructors
• You don't need to annotate inner classes
• RefreshScope have some problems when using with @Configuration. Please see this github issue

Change your class like this:

@ConfigurationProperties(prefix = "available-payment-channels-list")
@Configuration
public class AvailableChannelsConfiguration {

    private String xyz;
    private List<ChannelConfiguration> channelConfigurations;

    // getters, setters

    public static class ChannelConfiguration {
        private String name;
        private String companyBankAccount;

        // getters, setters
    }

}

Do

apachectl -k graceful

Try this for multiple CSS styles:

$(this).css({
    "background-color": 'red',
    "color" : "white"
});

If you are using generics, all answer will give us compile error. You can use return default(T);. Sample below to explain further.

public async Task<T> GetItemAsync<T>(string id)
            {
                try
                {
                    var response = await this._container.ReadItemAsync<T>(id, new PartitionKey(id));
                    return response.Resource;
                }
                catch (CosmosException ex) when (ex.StatusCode == System.Net.HttpStatusCode.NotFound)
                {

                    return default(T);
                }

            }

If you're using MySQL, there is a method REGEXP that you can use...

http://dev.mysql.com/doc/refman/5.1/en/regexp.html#operator_regexp

So then you would use:

SELECT * FROM `shirts` WHERE `colors` REGEXP '\b1\b'

Threaded:

    /// <summary>
    /// Usage: var timer = SetIntervalThread(DoThis, 1000);
    /// UI Usage: BeginInvoke((Action)(() =>{ SetIntervalThread(DoThis, 1000); }));
    /// </summary>
    /// <returns>Returns a timer object which can be disposed.</returns>
    public static System.Threading.Timer SetIntervalThread(Action Act, int Interval)
    {
        TimerStateManager state = new TimerStateManager();
        System.Threading.Timer tmr = new System.Threading.Timer(new TimerCallback(_ => Act()), state, Interval, Interval);
        state.TimerObject = tmr;
        return tmr;
    }

Regular

    /// <summary>
    /// Usage: var timer = SetInterval(DoThis, 1000);
    /// UI Usage: BeginInvoke((Action)(() =>{ SetInterval(DoThis, 1000); }));
    /// </summary>
    /// <returns>Returns a timer object which can be stopped and disposed.</returns>
    public static System.Timers.Timer SetInterval(Action Act, int Interval)
    {
        System.Timers.Timer tmr = new System.Timers.Timer();
        tmr.Elapsed += (sender, args) => Act();
        tmr.AutoReset = true;
        tmr.Interval = Interval;

        return tmr;
    }

You need the ip of the other pc and do:

scp user@ip_of_remote_pc:/home/user/stuff.php /Users/djorge/Desktop

it will ask you for 'user's password on the other pc.

There's no mystery here, the linker is telling you that you haven't defined the missing symbols, and you haven't.

Similarity::Similarity() or Similarity::~Similarity() are just missing and you have defined the others incorrectly,

void Similarity::readData(Scanner& inStream){
}

not

void readData(Scanner& inStream){
}

etc. etc.

The second one is a function called readData, only the first is the readData method of the Similarity class.

To be clear about this, in Similarity.h

void readData(Scanner& inStream);

but in Similarity.cpp

void Similarity::readData(Scanner& inStream){
}

Pickling will serialize your list (convert it, and it's entries to a unique byte string), so you can save it to disk. You can also use pickle to retrieve your original list, loading from the saved file.

So, first build a list, then use pickle.dump to send it to a file...

In my case I tried with all the options given here, but no one was working properly (angular 1.3.13, ionic 1.0.0, angular-ui-router 0.2.13). The solution was:

.state('tab.friends', {
      url: '/friends/:param1/:param2',
      views: {
        'tab-friends': {
          templateUrl: 'templates/tab-friends.html',
          controller: 'FriendsCtrl'
        }
      }
    })

and in the state.go:

$state.go('tab.friends', {param1 : val1, param2 : val2});

SELECT  MIN(Date)  AS Date  FROM tbl_Employee /*To get First date Of Employee*/

Just replace <img> tag to <object> tag for SVG image.

<object data="assets/twitter-wrap.svg" type="image/svg+xml"></object>

Tested!

In Windows -> control panel -> Region -> Additional Settings -> Time -> Short Time:

Format your time as HH:mm

in the format

hh = 12 hours

HH = 24 hours

mm = minutes

tt = AM or PM

so to get the required result the format should be HH:mm and not hh:mm tt

If you just want to calculate the schema size without tablespace free space and indexes :

select
   sum(bytes)/1024/1024 as size_in_mega,
   segment_type
from
   dba_segments
where
   owner='<schema's owner>'
group by
   segment_type;

For all schemas

select
   sum(bytes)/1024/1024 as size_in_mega, owner
from
   dba_segments
group by
  owner;

Button button1=(Button)findViewById(R.id.btnB1);
button1.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
MediaPlayer mp1 = MediaPlayer.create(this, R.raw.b1);
mp1.start();
}
});

Try this i think it will work

More than code in C, I think that an english definition could be enough:

Given a class Base of which there is a derived class Derived, dynamic_cast will convert a Base pointer to a Derived pointer if and only if the actual object pointed at is in fact a Derived object.

class Base { virtual ~Base() {} };
class Derived : public Base {};
class Derived2 : public Base {};
class ReDerived : public Derived {};

void test( Base & base )
{
   dynamic_cast<Derived&>(base);
}

int main() {
   Base b;
   Derived d;
   Derived2 d2;
   ReDerived rd;

   test( b );   // throw: b is not a Derived object
   test( d );   // ok
   test( d2 );  // throw: d2 is not a Derived object
   test( rd );  // ok: rd is a ReDerived, and thus a derived object
}

In the example, the call to test binds different objects to a reference to Base. Internally the reference is downcasted to a reference to Derived in a typesafe way: the downcast will succeed only for those cases where the referenced object is indeed an instance of Derived.

I go through various tool but found it to be really good and easy.

More accurate for Edge (do not include latest IE 15) is:

@supports (display:-ms-grid) { ... }

@supports (-ms-ime-align:auto) { ... } works for all Edge versions (currently up to IE15).

Use a library like LumenWorks to do your CSV reading. It'll handle fields with quotes in them and will likely overall be more robust than your custom solution by virtue of having been around for a long time.

Date arithmetic is not needed if you just want to display the same timestamp in different timezones:

$format = "M d, Y h:ia";
$timestamp = gmdate($format);

date_default_timezone_set("UTC");
$utc_datetime = date($format, $timestamp);

date_default_timezone_set("America/Guayaquil");
$local_datetime = date($format, $timestamp);

By using the Robot class in Java:

import java.awt.Robot;
import java.awt.event.KeyEvent;

public class Test1
{
    public static void main(String[] args) throws Exception
    {
        WebDriver d1 = new FirefoxDriver();
        d1.navigate().to("https://www.youtube.com/");
        Thread.sleep(3000);
        Robot rb = new Robot();
        rb.keyPress(KeyEvent.VK_TAB);
        rb.keyRelease(KeyEvent.VK_TAB);
        rb.keyPress(KeyEvent.VK_TAB);
        rb.keyRelease(KeyEvent.VK_TAB);

        // Perform [Ctrl+A] Operation - it works
        rb.keyPress(KeyEvent.VK_CONTROL);
        rb.keyPress(KeyEvent.VK_A);

        // It needs to release key after pressing
        rb.keyRelease(KeyEvent.VK_A);
        rb.keyRelease(KeyEvent.VK_CONTROL);
        Thread.sleep(3000);
    }
}

You could use the or operator:

return x or "default"

Note that this also returns "default" if x is any falsy value, including an empty list, 0, empty string, or even datetime.time(0) (midnight).

If lakes is your DataFrame, you can do something like

area_dict = dict(zip(lakes.area, lakes.count))

In the few words - function returns something. You can use function in SQL query. Procedure is part of code to do something with data but you can not invoke procedure from query, you have to run it in PL/SQL block.

For the timer part of your script i highly reccomend using:

echo.
echo Waiting For One Hour... 
TIMEOUT /T 3600 /NOBREAK
echo.
echo (Put some Other Processes Here)
echo.
pause >nul

This script waits for 1 hour (3600 seconds) and then continues on with the script and the user cannot press any buttons to bypass the timer (besides CTRL+C).

You can use

Timeout /t 3600 /nobreak >nul

If you don't want to see a countdown on the screen.

I had this issue when after rebooted and the last copy of VSCode reopened. The above fix did not work, but when I closed and reopened VSCode via explorer it worked. Here are the steps I did:

//received fatal error_x000D_
git remote remove origin_x000D_
git init_x000D_
git remote add origin git@github:<yoursite>/<your project>.git_x000D_
// still received an err _x000D_
//restarted VSCode and folder via IE _x000D_
//updated one char and resaved the index.html  _x000D_
git add ._x000D_
git commit -m "blah"_x000D_
git push origin master

One can also use the java.util.EnumSet like this

@Test
void test(){
    Enum aEnum =DayOfWeek.MONDAY;
    printAll(aEnum);
}

void printAll(Enum value){
    Set allValues = EnumSet.allOf(value.getClass());
    System.out.println(allValues);
}

If insertion order matters, take a look at collections.OrderedDict:

An OrderedDict is a dict that remembers the order that keys were first inserted. If a new entry overwrites an existing entry, the original insertion position is left unchanged. Deleting an entry and reinserting it will move it to the end.

In [1]: from collections import OrderedDict

In [2]: od = OrderedDict(zip('bar','foo'))

In [3]: od
Out[3]: OrderedDict([('b', 'f'), ('a', 'o'), ('r', 'o')])

In [4]: od.keys()[-1]
Out[4]: 'r'

In [5]: od.popitem() # also removes the last item
Out[5]: ('r', 'o')

Update:

An OrderedDict is no longer necessary as dictionary keys are officially ordered in insertion order as of Python 3.7 (unofficially in 3.6).

For these recent Python versions, you can instead just use list(my_dict)[-1] or list(my_dict.keys())[-1].

In NodeJS, __filename.split(/\|//).pop() returns just the file name from the absolute file path on any OS platform. Why need to care about remembering/importing an API while this regex approach also letting us recollect our regex skills.

You can't do it using environment variables directly. You need to use the set of "non standard" options that are passed to the java command. Run: java -X for details. The options you're looking for are -Xmx and -Xms (this is "initial" heap size, so probably what you're looking for.)

Some products like Ant or Tomcat might come with a batch script that looks for the JAVA_OPTS environment variable, but it's not part of the Java runtime. If you are using one of those products, you may be able to set the variable like:

set JAVA_OPTS="-Xms128m -Xmx256m"  

You can also take this approach with your own command line like:

set JAVA_OPTS="-Xms128m -Xmx256m"  
java ${JAVA_OPTS} MyClass

Since PostgreSQL 9.1 there is the convenient FOREACH:

DO
$do$
DECLARE
   m   varchar[];
   arr varchar[] := array[['key1','val1'],['key2','val2']];
BEGIN
   FOREACH m SLICE 1 IN ARRAY arr
   LOOP
      RAISE NOTICE 'another_func(%,%)',m[1], m[2];
   END LOOP;
END
$do$

Solution for older versions:

DO
$do$
DECLARE
   arr varchar[] := '{{key1,val1},{key2,val2}}';
BEGIN
   FOR i IN array_lower(arr, 1) .. array_upper(arr, 1)
   LOOP
      RAISE NOTICE 'another_func(%,%)',arr[i][1], arr[i][2];
   END LOOP;
END
$do$

Also, there is no difference between varchar[] and varchar[][] for the PostgreSQL type system. I explain in more detail here.

The DO statement requires at least PostgreSQL 9.0, and LANGUAGE plpgsql is the default (so you can omit the declaration).

Is there some simple equivalent to this keyword in C++?

No.

Depending on what you're trying to accomplish, there might be adequate (or even better) substitutes.

I've looked through some STL code (on linux, I think it's the one deriving from SGI's implementation). It has "concept assertions"; for instance, if you require a type which understands *x and ++x, the concept assertion would contain that code in a do-nothing function (or something similar). It does require some overhead, so it might be smart to put it in a macro whose definition depends on #ifdef debug.

If the subclass relationship is really what you want to know about, you could assert in the constructor that T instanceof list (except it's "spelled" differently in C++). That way, you can test your way out of the compiler not being able to check it for you.

You can use @Qualifier along with @Autowired. In fact spring will ask you explicitly select the bean if ambiguous bean type are found, in which case you should provide the qualifier

For Example in following case it is necessary provide a qualifier

@Component
@Qualifier("staff") 
public Staff implements Person {}

@Component
@Qualifier("employee") 
public Manager implements Person {}


@Component
public Payroll {

    private Person person;

    @Autowired
    public Payroll(@Qualifier("employee") Person person){
          this.person = person;
    }

}

EDIT:

In Lombok 1.18.4 it is finally possible to avoid the boilerplate on constructor injection when you have @Qualifier, so now it is possible to do the following:

@Component
@Qualifier("staff") 
public Staff implements Person {}

@Component
@Qualifier("employee") 
public Manager implements Person {}


@Component
@RequiredArgsConstructor
public Payroll {
   @Qualifier("employee") private final Person person;
}

provided you are using the new lombok.config rule copyableAnnotations (by placing the following in lombok.config in the root of your project):

# Copy the Qualifier annotation from the instance variables to the constructor
# see https://github.com/rzwitserloot/lombok/issues/745
lombok.copyableAnnotations += org.springframework.beans.factory.annotation.Qualifier

This was recently introduced in latest lombok 1.18.4.

• The blog post where the issue is discussed in detail
• The original issue on github
• And a small github project to see it in action

NOTE

If you are using field or setter injection then you have to place the @Autowired and @Qualifier on top of the field or setter function like below(any one of them will work)

public Payroll {
   @Autowired @Qualifier("employee") private final Person person;
}

or

public Payroll {
   private final Person person;
   @Autowired
   @Qualifier("employee")
   public void setPerson(Person person) {
     this.person = person;
   } 
}

If you are using constructor injection then the annotations should be placed on constructor, else the code would not work. Use it like below -

public Payroll {

    private Person person;

    @Autowired
    public Payroll(@Qualifier("employee") Person person){
          this.person = person;
    }

}

There is hurry.filesize that will take the size in bytes and make a nice string out if it.

>>> from hurry.filesize import size
>>> size(11000)
'10K'
>>> size(198283722)
'189M'

Or if you want 1K == 1000 (which is what most users assume):

>>> from hurry.filesize import size, si
>>> size(11000, system=si)
'11K'
>>> size(198283722, system=si)
'198M'

It has IEC support as well (but that wasn't documented):

>>> from hurry.filesize import size, iec
>>> size(11000, system=iec)
'10Ki'
>>> size(198283722, system=iec)
'189Mi'

Because it's written by the Awesome Martijn Faassen, the code is small, clear and extensible. Writing your own systems is dead easy.

Here is one:

mysystem = [
    (1024 ** 5, ' Megamanys'),
    (1024 ** 4, ' Lotses'),
    (1024 ** 3, ' Tons'), 
    (1024 ** 2, ' Heaps'), 
    (1024 ** 1, ' Bunches'),
    (1024 ** 0, ' Thingies'),
    ]

Used like so:

>>> from hurry.filesize import size
>>> size(11000, system=mysystem)
'10 Bunches'
>>> size(198283722, system=mysystem)
'189 Heaps'

Since PHP 7.3 the hrtime function should be used for any timing.

$start = hrtime(true);
// execute...
$end = hrtime(true);   

echo ($end - $start);                // Nanoseconds
echo ($end - $start) / 1000000000;   // Seconds

The mentioned microtime function relies on the system clock. Which can be modified e.g. by the ntpd program on ubuntu or just the sysadmin.

I would take a look at the BinaryReader and BinaryWriter classes. I recently had to serialize data to a byte array (and back) and only found these classes after I'd basically rewritten them myself.

http://msdn.microsoft.com/en-us/library/system.io.binarywriter.aspx

There is a good example on that page too.

Best way to pass data from child to parent component

child component

handleLanguageCode=()=>(langValue) {
  this.props.sendDatatoParent(langValue)
}

Parent

<Parent sendDatatoParent={ data => this.setState({item: data}) } />;

git branch --set-upstream <<origin/branch>> is officially not supported anymore and is replaced by git branch --set-upstream-to <<origin/branch>>

Well, if you can use Tcl/Tk in your environment, you probably should write a TCL script and use that. You might also look at wish.

If you need to popback from the fourth fragment in the backstack history to the first, use tags!!!

When you add the first fragment you should use something like this:

getFragmentManager.beginTransaction.addToBackStack("A").add(R.id.container, FragmentA).commit() 

or

getFragmentManager.beginTransaction.addToBackStack("A").replace(R.id.container, FragmentA).commit()

And when you want to show Fragments B,C and D you use this:

getFragmentManager.beginTransaction.addToBackStack("B").replace(R.id.container, FragmentB, "B").commit()

and other letters....

To return to Fragment A, just call popBackStack(0, "A"), yes, use the flag that you specified when you add it, and note that it must be the same flag in the command addToBackStack(), not the one used in command replace or add.

You're welcome ;)

import serial
ser = serial.Serial(0)  # open first serial port
print ser.portstr       # check which port was really used
ser.write("hello")      # write a string
ser.close()             # close port

It’s because you tried to update a table without a WHERE that uses a KEY column.

The quick fix is to add SET SQL_SAFE_UPDATES=0; before your query :

SET SQL_SAFE_UPDATES=0; 

Or

close the safe update mode. Edit -> Preferences -> SQL Editor -> SQL Editor remove Forbid UPDATE and DELETE statements without a WHERE clause (safe updates) .

BTW you can use TRUNCATE TABLE tablename; to delete all the records .

There is a problem with every answer provided that can be summarized as "just add this magical incantation to the beginning of your script. See what you can do with just a line or two of code." They will not work in every possible situation!

For example, one such magical incantation uses __file__. Unfortunately, if you package your script using cx_Freeze or you are using IDLE, this will result in an exception.

Another such magical incantation uses os.getcwd(). This will only work if you are running your script from the command prompt and the directory containing your script is the current working directory (that is you used the cd command to change into the directory prior to running the script). Eh gods! I hope I do not have to explain why this will not work if your Python script is in the PATH somewhere and you ran it by simply typing the name of your script file.

Fortunately, there is a magical incantation that will work in all the cases I have tested. Unfortunately, the magical incantation is more than just a line or two of code.

import inspect
import os
import sys

# Add script directory to sys.path.
# This is complicated due to the fact that __file__ is not always defined.

def GetScriptDirectory():
    if hasattr(GetScriptDirectory, "dir"):
        return GetScriptDirectory.dir
    module_path = ""
    try:
        # The easy way. Just use __file__.
        # Unfortunately, __file__ is not available when cx_Freeze is used or in IDLE.
        module_path = __file__
    except NameError:
        if len(sys.argv) > 0 and len(sys.argv[0]) > 0 and os.path.isabs(sys.argv[0]):
            module_path = sys.argv[0]
        else:
            module_path = os.path.abspath(inspect.getfile(GetScriptDirectory))
            if not os.path.exists(module_path):
                # If cx_Freeze is used the value of the module_path variable at this point is in the following format.
                # {PathToExeFile}\{NameOfPythonSourceFile}. This makes it necessary to strip off the file name to get the correct
                # path.
                module_path = os.path.dirname(module_path)
    GetScriptDirectory.dir = os.path.dirname(module_path)
    return GetScriptDirectory.dir

sys.path.append(os.path.join(GetScriptDirectory(), "lib"))
print(GetScriptDirectory())
print(sys.path)

As you can see, this is no easy task!

Just use a bytearray() which is a list of bytes.

Python2:

s = "ABCD"
b = bytearray()
b.extend(s)

Python3:

s = "ABCD"
b = bytearray()
b.extend(map(ord, s))

By the way, don't use str as a variable name since that is builtin.

`$` sudo service redis-server stop

Does the trick.

I killed related w3wp.exe (on a friends' advise) at task manager and it worked.

Note: Use at your own risk. Be careful picking which one to kill.

Less SELECT statements. Also, less performance consuming. Credits to: [email protected]

SELECT *
    FROM   (SELECT t.*,
                   rownum AS rn
            FROM   shhospede t) a
    WHERE  a.rn >= in_first
    AND    a.rn <= in_first;

Old Answer it is kind of confusing. It gives you the LOCATIONS (all of them) of where your statment is true.

so:

>>> a = np.arange(100)
>>> np.where(a > 30)
(array([31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47,
       48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64,
       65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81,
       82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98,
       99]),)
>>> np.where(a == 90)
(array([90]),)

a = a*40
>>> np.where(a > 1000)
(array([26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42,
       43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59,
       60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76,
       77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93,
       94, 95, 96, 97, 98, 99]),)
>>> a[25]
1000
>>> a[26]
1040

I use it as an alternative to list.index(), but it has many other uses as well. I have never used it with 2D arrays.

http://docs.scipy.org/doc/numpy/reference/generated/numpy.where.html

New Answer It seems that the person was asking something more fundamental.

The question was how could YOU implement something that allows a function (such as where) to know what was requested.

First note that calling any of the comparison operators do an interesting thing.

a > 1000
array([False, False, False, False, False, False, False, False, False,
       False, False, False, False, False, False, False, False, False,
       False, False, False, False, False, False, False, False,  True,
        True,  True,  True,  True,  True,  True,  True,  True,  True,
        True,  True,  True,  True,  True,  True,  True,  True,  True,
        True,  True,  True,  True,  True,  True,  True,  True,  True,
        True,  True,  True,  True,  True,  True,  True,  True,  True,
        True,  True,  True,  True,  True,  True,  True,  True,  True,
        True,  True,  True,  True,  True,  True,  True,  True,  True,
        True,  True,  True,  True,  True,  True,  True,  True,  True,
        True`,  True,  True,  True,  True,  True,  True,  True,  True,  True], dtype=bool)`

This is done by overloading the "__gt__" method. For instance:

>>> class demo(object):
    def __gt__(self, item):
        print item


>>> a = demo()
>>> a > 4
4

As you can see, "a > 4" was valid code.

You can get a full list and documentation of all overloaded functions here: http://docs.python.org/reference/datamodel.html

Something that is incredible is how simple it is to do this. ALL operations in python are done in such a way. Saying a > b is equivalent to a.gt(b)!

import java.util.*;

public class Main{

     int recursionDepth = 0;
     private int[][] memo;

     public static void main(String []args){
         int[] nums = new int[] {5,2,4,3,1};
         int N = nums.length;
         Main main =  new Main();
         main.memo = new int[N+1][N+1];
         main._findCombo(0, N-1,nums, 8, 0, new LinkedList() );
         System.out.println(main.recursionDepth);
     }


       private void _findCombo(
           int from,
           int to,
           int[] nums,
           int targetSum,
           int currentSum,
           LinkedList<Integer> list){

            if(memo[from][to] != 0) {
                currentSum = currentSum + memo[from][to];
            }

            if(currentSum > targetSum) {
                return;
            }

            if(currentSum ==  targetSum) {
                System.out.println("Found - " +list);
                return;
            }

            recursionDepth++;

           for(int i= from ; i <= to; i++){
               list.add(nums[i]);
               memo[from][i] = currentSum + nums[i];
               _findCombo(i+1, to,nums, targetSum, memo[from][i], list);
                list.removeLast();
           }

     }
}

If you use find from GNU fileutils:

size=$( find . -maxdepth 1 -type f -name filename -printf '%s' )

Unfortunately, other implementations of find usually don't support -maxdepth, nor -printf. This is the case for e.g. Solaris and macOS find.

Please put your related value and try this :

declare @x int, @y varchar(200),
        @dt1 smalldatetime = '2014-01-21 10:00:00', 
        @dt2 smalldatetime = getdate()

set @x = datediff (HOUR, @dt1, @dt2)
set @y =  @x * 60 -  DATEDIFF(minute,@dt1, @dt2)
set @y = cast(@x as varchar(200)) + ':' + @y
Select @y

Make sure that your code is returning a value of given return-type irrespective of conditional statements

This code snippet was showing the same error

int search(char arr[], int start, int end, char value)
{
    int i;
    for(i=start; i<=end; i++)
    {
        if(arr[i] == value)
            return i;
    }
}

This is the working code after little changes

int search(char arr[], int start, int end, char value)
{
    int i;
    int index=-1;
    for(i=start; i<=end; i++)
    {
        if(arr[i] == value)
            index=i;
    }
    return index;
}

I don't think it provides a multi-hop wireless packet routing environment. However you can try to integrate a simple routing mechanism. Just check out Wi-Share to get an idea how it can be done.

Please, please, and pretty please do not try this at home, or work, or anywhere really.

This is a way solve to a very very specific problem, and I hope you will not have that.

I'm posting this since it is technically an answer, and another perspective to look at it.

I repeat, do not use it under any condition. Code is to run with LINQPad.

void Main()
{
    (new A(1)).Dump();
    (new B(2, -1)).Dump();
    
    var b2 = new B(2, -1);
    b2.Increment();
    
    b2.Dump();
}

class A 
{
    public readonly int I = 0;
    
    public A(int i)
    {
        I = i;
    }
}

class B: A
{
    public int J;
    public B(int i, int j): base(i)
    {
        J = j;
    }
    
    public B(int i, bool wtf): base(i)
    {
    }
    
    public void Increment()
    {
        int i = I + 1;

        var t = typeof(B).BaseType;
        var ctor = t.GetConstructors().First();
        
        ctor.Invoke(this, new object[] { i });
    }
}

Since constructor is a method, you can call it with reflection. Now you either think with portals, or visualize a picture of a can of worms. sorry about this.

If you want to use the same library folder for several projects, you can reference it in gradle to an external location like this:

settings.gradle:

include 'app', ':volley'
project(':volley').projectDir = new File('../libraries/volley')

in your app build.gradle

dependencies {
    ...
    compile project(':volley')
...}

These are URLs that work:

http://maps.google.com/?q=<LAT>,<LNG>

https://maps.google.com/?q=<LAT>,<LNG>&ll=<LAT>,<LNG>&z=18

https://www.google.com/maps/@<LAT>,<LNG>,16z

https://maps.google.com/?q=<LAT>,<LNG>&z=16

Although (for avid readers) This is the latest from google (August 22 2017):

Maps URLs
Maps URLs with map display
Maps URLs with search action

From google

Search: When searching for a specific place, the resulting map puts a pin in the specified location and displays available place details.

Important: The parameter api=1 identifies the version of Maps URLs this URL is intended for. This parameter is required in every request. The only valid value is 1. If api=1 is NOT present in the URL, all parameters are ignored and the default Google Maps app will launch, either in a browser or the Google Maps mobile app, depending on the platform in use (for example, https://www.google.com/maps).

Well, from my understanding, simply for matching this format in a given string, I prefer this regular expression:

pattern='[0-9|/]+'

to match the format in a more strict way, the following works:

pattern='(?:[0-9]{2}/){2}[0-9]{2}'

Personally, I cannot agree with unutbu's answer since sometimes we use regular expression for "finding" and "extract", not only "validating".

Just run graphics.off() before plotting your data. This instruction solved my error. So, it's harmless to try it before taking a more complex solution.

The simplest and best way to get yesterday's date is:

subdate(current_date, 1)

Your query would be:

SELECT 
    url as LINK,
    count(*) as timesExisted,
    sum(DateVisited between UNIX_TIMESTAMP(subdate(current_date, 1)) and
        UNIX_TIMESTAMP(current_date)) as timesVisitedYesterday
FROM mytable
GROUP BY 1

For the curious, the reason that sum(condition) gives you the count of rows that satisfy the condition, which would otherwise require a cumbersome and wordy case statement, is that in mysql boolean values are 1 for true and 0 for false, so summing a condition effectively counts how many times it's true. Using this pattern can neaten up your SQL code.

This is a very simple script to solve the problem

export JAVA_HOME_BIN=`which java`
export JAVA_HOME_DIR=`dirname $JAVA_HOME_BIN`
export JAVA_HOME=`dirname $JAVA_HOME_DIR`

And for testing:

echo $JAVA_HOME

In Visual Studio 2008 (and probably later), the free DevExpress CodeRush Xpress add-in supplies Ctrl+Alt+F, Quick File Navigation, which searches on an exact substring in the file name or on capital letters.

(Unrelated to this answer, but note the rather more useful, Quick Navigation, Ctrl+Shift+Q, which I would have liked to have known about before now :-) )

for me, it was because of all the outgoing files, i.e workspace is not in sync with SVN, due to the 'target' folders (maven project, or when building web project), add them to svn:ignore.

Try this:

import os
for top, dirs, files in os.walk('./'):
    for nm in files:       
        print os.path.join(top, nm)

You'll need to get a compiler. The easiest way is probably to install XCode development environment from the CDs/DVDs you got with your Mac, which will give you gcc. Then you should be able compile it like

gcc -o mybinaryfile mysourcefile.c

@The Thunder Chimp You can split text in such a way that some sections are affected by super(or sub) script and others aren't through the use of *. For your example, with splitting the word "moment" from "4th" -

plot(rnorm(30), xlab = expression('4'^th*'moment'))

I just ran into a similar problem and devised a small optimization for the case where no object in the list meets the requirement.(for my use-case this resulted in major performance improvement):

Along with the list test_list, I keep an additional set test_value_set which consists of values of the list that I need to filter on. So here the else part of agf's solution becomes very-fast.

I use the below query

SELECT   SPID       = er.session_id
    ,STATUS         = ses.STATUS
    ,[Login]        = ses.login_name
    ,Host           = ses.host_name
    ,BlkBy          = er.blocking_session_id
    ,DBName         = DB_Name(er.database_id)
    ,CommandType    = er.command
    ,ObjectName     = OBJECT_NAME(st.objectid)
    ,CPUTime        = er.cpu_time
    ,StartTime      = er.start_time
    ,TimeElapsed    = CAST(GETDATE() - er.start_time AS TIME)
    ,SQLStatement   = st.text
FROM    sys.dm_exec_requests er
    OUTER APPLY sys.dm_exec_sql_text(er.sql_handle) st
    LEFT JOIN sys.dm_exec_sessions ses
    ON ses.session_id = er.session_id
LEFT JOIN sys.dm_exec_connections con
    ON con.session_id = ses.session_id
WHERE   st.text IS NOT NULL

In your layout xml do the following:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">

    <solid android:color="@android:color/holo_red_dark" />

    <corners android:radius="32dp" />

</shape>

By changing the android:radius you can change the amount of "radius" of the corners.

<solid> is used to define the color of the drawable.

You can use replace android:radius with android:bottomLeftRadius, android:bottomRightRadius, android:topLeftRadius and android:topRightRadius to define radius for each corner.

I find this particularly useful for when you want to 'store' a function call.

For example, suppose I have some unit tests for a function 'add':

def add(a, b): return a + b
tests = { (1,4):5, (0, 0):0, (-1, 3):3 }
for test, result in tests.items():
    print 'test: adding', test, '==', result, '---', add(*test) == result

There is no other way to call add, other than manually doing something like add(test[0], test[1]), which is ugly. Also, if there are a variable number of variables, the code could get pretty ugly with all the if-statements you would need.

Another place this is useful is for defining Factory objects (objects that create objects for you). Suppose you have some class Factory, that makes Car objects and returns them. You could make it so that myFactory.make_car('red', 'bmw', '335ix') creates Car('red', 'bmw', '335ix'), then returns it.

def make_car(*args):
    return Car(*args)

This is also useful when you want to call a superclass' constructor.

I've fixed it. I had the following section in web.config :

httpErrors existingResponse="PassThrough"

When I remove it, I got a real error

I had the similar issue and i solved it using:

background:url(images/banner1.png) no-repeat center top scroll;
background-size: 100% auto;
padding-bottom: 50%;

... here i had to add the padding: 50% because it wasn't working for me otherwise. It allowed me to set the height of container, as per the size ratio of my banner image. and it is also responsive in my case.

i came across a similar situation using booleans where I wanted to avoid calling b() if a was already false.

This worked for me:

a &= a && b()

You can use the newly created jar using a <classifier> tag.

<dependencies>
    <dependency>
        <groupId>your.group.id</groupId>
        <artifactId>your.artifact.id</artifactId>
        <version>1.0</version>
        <type>jar</type>
        <classifier>jar-with-dependencies</classifier>
    </dependency>
</dependencies>

When I try these solutions.
I solved with:
create a new virtual device( select Google APIs(Google Inc)-API Level 15 replace android 4.0.3-APILevel 15 ) then run again. It solved.

I think it's just because the device have no google apis~

IDE:android-studio OS:ubuntu 12.04

one line solution: basic idea:

$('sth').click(function () {
    let COND = $(this).propery == 'cond1' ? 'cond2' : 'cond1';
    doSomeThing(COND);
})

examples on jsfiddle

example 1, changing innerHTML of an element in a toggle-mode:

$('#clickTest1').click(function () {
    $(this).html($(this).html() == 'click Me' ? 'clicked' : 'click Me');
});

example 2, toggling displays between "none" and "inline-block":

$('#clickTest2, #clickTest2 > span').click(function () {
    $(this).children().css('display', $(this).children().css('display') == 'inline-block' ? 'none' : 'inline-block');
});

None of the previous answers worked for me. What did end up working for my situation (which was seeing that padding after dynamically adding a header to my Table View) was selecting the Navigation Bar from the Document Outline and rechecking the Translucent box (contrary to some answers that were saying to force it to be translucent). I had previously unchecked it because it had made my red look a little orange, but I could not try the solution of reordering the elements in the scene since the Table View was the only element in this scene. This solution works as long as you are okay with the Navigation Bar's color having a translucent layer over it. Hope this helps :)

This works for me ..

PNG supports alphachannel transparency.

TIFF can have extended options I.e. Geo referencing for GIS applications.

I recommend only ever using JPEG for photographs, never for images like clip art, logos, text, diagrams, line art.

Favor PNG.

For strings in general, is it always a good idea to use the copy attribute instead of retain?

Yes - in general always use the copy attribute.

This is because your NSString property can be passed an NSString instance or an NSMutableString instance, and therefore we can not really determine if the value being passed is an immutable or mutable object.

Is a "copied" property in any way less efficient than such a "retain-ed" property?

• If your property is being passed an NSString instance, the answer is "No" - copying is not less efficient than retain.
  (It's not less efficient because the NSString is smart enough to not actually perform a copy.)

• If your property is passed an NSMutableString instance then the answer is "Yes" - copying is less efficient than retain.
  (It's less efficient because an actual memory allocation and copy must occur, but this is probably a desirable thing.)

• Generally speaking a "copied" property has the potential to be less efficient - however through the use of the NSCopying protocol, it's possible to implement a class which is "just as efficient" to copy as it is to retain. NSString instances are an example of this.

Generally (not just for NSString), when should I use "copy" instead of "retain"?

You should always use copy when you don't want the internal state of the property changing without warning. Even for immutable objects - properly written immutable objects will handle copy efficiently (see next section regarding immutability and NSCopying).

There may be performance reasons to retain objects, but it comes with a maintenance overhead - you must manage the possibility of the internal state changing outside your code. As they say - optimize last.

But, I wrote my class to be immutable - can't I just "retain" it?

No - use copy. If your class is really immutable then it's best practice to implement the NSCopying protocol to make your class return itself when copy is used. If you do this:

• Other users of your class will gain the performance benefits when they use copy.
• The copy annotation makes your own code more maintainable - the copy annotation indicates that you really don't need to worry about this object changing state elsewhere.

The previous answer is correct but I'll give you all the code as well.

Your app.config should look like this:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
   <configSections>
      <section name="ServicesSection" type="RT.Core.Config.ServiceConfigurationSection, RT.Core"/>
   </configSections>
   <ServicesSection>
      <Services>
         <add Port="6996" ReportType="File" />
         <add Port="7001" ReportType="Other" />
      </Services>
   </ServicesSection>
</configuration>

Your ServiceConfig and ServiceCollection classes remain unchanged.

You need a new class:

public class ServiceConfigurationSection : ConfigurationSection
{
   [ConfigurationProperty("Services", IsDefaultCollection = false)]
   [ConfigurationCollection(typeof(ServiceCollection),
       AddItemName = "add",
       ClearItemsName = "clear",
       RemoveItemName = "remove")]
   public ServiceCollection Services
   {
      get
      {
         return (ServiceCollection)base["Services"];
      }
   }
}

And that should do the trick. To consume it you can use:

ServiceConfigurationSection serviceConfigSection =
   ConfigurationManager.GetSection("ServicesSection") as ServiceConfigurationSection;

ServiceConfig serviceConfig = serviceConfigSection.Services[0];

The fact the character is a < make me think you have a PHP error, have you tried echoing all errors.

Since I don't have your database, I'm going through your code trying to find errors, so far, I've updated your JS file

$("#register-form").submit(function (event) {

    var entrance = $(this).find('input[name="IsValid"]').val();
    var password = $(this).find('input[name="objPassword"]').val();
    var namesurname = $(this).find('input[name="objNameSurname"]').val();
    var email = $(this).find('input[name="objEmail"]').val();
    var gsm = $(this).find('input[name="objGsm"]').val();
    var adres = $(this).find('input[name="objAddress"]').val();
    var termsOk = $(this).find('input[name="objAcceptTerms"]').val();

    var formURL = $(this).attr("action");


    if (request) {
        request.abort(); // cancel if any process on pending
    }

    var postData = {
        "objAskGrant": entrance,
        "objPass": password,
        "objNameSurname": namesurname,
        "objEmail": email,
        "objGsm": parseInt(gsm),
        "objAdres": adres,
        "objTerms": termsOk
    };

    $.post(formURL,postData,function(data,status){
        console.log("Data: " + data + "\nStatus: " + status);
    });

    event.preventDefault();
});

PHP Edit:

 if (isset($_POST)) {

    $fValid = clear($_POST['objAskGrant']);
    $fTerms = clear($_POST['objTerms']);

    if ($fValid) {
        $fPass = clear($_POST['objPass']);
        $fNameSurname = clear($_POST['objNameSurname']);
        $fMail = clear($_POST['objEmail']);
        $fGsm = clear(int($_POST['objGsm']));
        $fAddress = clear($_POST['objAdres']);
        $UserIpAddress = "hidden";
        $UserCityLocation = "hidden";
        $UserCountry = "hidden";

        $DateTime = new DateTime();
        $result = $date->format('d-m-Y-H:i:s');
        $krr = explode('-', $result);
        $resultDateTime = implode("", $krr);

        $data = array('error' => 'Yükleme Sirasinda Hata Olustu');

        $kayit = "INSERT INTO tbl_Records(UserNameSurname, UserMail, UserGsm, UserAddress, DateAdded, UserIp, UserCityLocation, UserCountry, IsChecked, GivenPasscode) VALUES ('$fNameSurname', '$fMail', '$fGsm', '$fAddress', '$resultDateTime', '$UserIpAddress', '$UserCityLocation', '$UserCountry', '$fTerms', '$fPass')";
        $retval = mysql_query( $kayit, $conn ); // Update with you connection details
            if ($retval) {
                $data = array('success' => 'Register Completed', 'postData' => $_POST);
            }

        } // valid ends
    }echo json_encode($data);

new XElement("Foo",
       from s in nameValuePairList
       select
             new XElement("Bar",
                  new XAttribute("SomeAttr", "SomeAttrValue"),
                          new XElement("Name", s.Name),
                          new XElement("Value", s.Value)
                         )
            );

I cross that situation by replacing all androidx.* to appropiate package name.

change your line

implementation 'androidx.appcompat:appcompat:1.0.0-alpha3'
implementation 'androidx.constraintlayout:constraintlayout:1.1.1'

androidTestImplementation 'androidx.test:runner:1.1.0-alpha3'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0-alpha3'

to

implementation 'com.android.support:appcompat-v7:28.0.0-alpha3'
implementation 'com.android.support.constraint:constraint-layout:1.1.1'

androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

NOTED

• remove tools:replace="android:appComponentFactory" from AndroidManifest

The accepted answer here does not work if you have inline scripts in your document. To avoid this you can use the following to only target <script> tags with a [src] attribute.

/**
 * Current Script Path
 *
 * Get the dir path to the currently executing script file
 * which is always the last one in the scripts array with
 * an [src] attr
 */
var currentScriptPath = function () {

    var scripts = document.querySelectorAll( 'script[src]' );
    var currentScript = scripts[ scripts.length - 1 ].src;
    var currentScriptChunks = currentScript.split( '/' );
    var currentScriptFile = currentScriptChunks[ currentScriptChunks.length - 1 ];

    return currentScript.replace( currentScriptFile, '' );
}

This effectively captures the last external .js file, solving some issues I encountered with inline JS templates.

There is no => for if.
Use if %energy% GEQ %m2enc%

See if /? for some other details.

You cat try with below command

cat log|grep -e word1 -e word2

Possible problems and solutions

1. Limitation of number of usable overlay icons by Windows, refer to Kris Erickson's answer.
2. Inappropriate setting of TortoiseSVN, refer to Ralph Cowling's answer.
3. Known bug for updating from earlier version (pre 1.6.10), see here.
4. TortoiseSVN was not installed for all users, try to install with cmd like below, if all below three solutions don't work, I believe this method will save your life.
