Your mock is raising the exception just fine, but the error.resp.status value is missing. Rather than use return_value, just tell Mock that status is an attribute:

barMock.side_effect = HttpError(mock.Mock(status=404), 'not found')

Additional keyword arguments to Mock() are set as attributes on the resulting object.

I put your foo and bar definitions in a my_tests module, added in the HttpError class so I could use it too, and your test then can be ran to success:

>>> from my_tests import foo, HttpError
>>> import mock
>>> with mock.patch('my_tests.bar') as barMock:
...     barMock.side_effect = HttpError(mock.Mock(status=404), 'not found')
...     result = my_test.foo()
... 
404 - 
>>> result is None
True

You can even see the print '404 - %s' % error.message line run, but I think you wanted to use error.content there instead; that's the attribute HttpError() sets from the second argument, at any rate.

You could avoid changing the code (although I recommend Boris' answer) and mock the constructor, like in this example for mocking the creation of a File object inside a method. Don't forget to put the class that will create the file in the @PrepareForTest.

package hello.easymock.constructor;

import java.io.File;

import org.easymock.EasyMock;
import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.powermock.api.easymock.PowerMock;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;
    
@RunWith(PowerMockRunner.class)
@PrepareForTest({File.class})
public class ConstructorExampleTest {
        
    @Test
    public void testMockFile() throws Exception {

        // first, create a mock for File
        final File fileMock = EasyMock.createMock(File.class);
        EasyMock.expect(fileMock.getAbsolutePath()).andReturn("/my/fake/file/path");
        EasyMock.replay(fileMock);

        // then return the mocked object if the constructor is invoked
        Class<?>[] parameterTypes = new Class[] { String.class };
        PowerMock.expectNew(File.class, parameterTypes , EasyMock.isA(String.class)).andReturn(fileMock);
        PowerMock.replay(File.class); 
    
        // try constructing a real File and check if the mock kicked in
        final String mockedFilePath = new File("/real/path/for/file").getAbsolutePath();
        Assert.assertEquals("/my/fake/file/path", mockedFilePath);
    }
}

Stub

I believe the biggest distinction is that a stub you have already written with predetermined behavior. So you would have a class that implements the dependency (abstract class or interface most likely) you are faking for testing purposes and the methods would just be stubbed out with set responses. They would not do anything fancy and you would have already written the stubbed code for it outside of your test.

Mock

A mock is something that as part of your test you have to setup with your expectations. A mock is not setup in a predetermined way so you have code that does it in your test. Mocks in a way are determined at runtime since the code that sets the expectations has to run before they do anything.

Difference between Mocks and Stubs

Tests written with mocks usually follow an initialize -> set expectations -> exercise -> verify pattern to testing. While the pre-written stub would follow an initialize -> exercise -> verify.

Similarity between Mocks and Stubs

The purpose of both is to eliminate testing all the dependencies of a class or function so your tests are more focused and simpler in what they are trying to prove.

In simpler terms, Imagine if you want mock below line:

StaticClass.method();

then you write below lines of code to mock:

PowerMockito.mockStatic(StaticClass.class);
PowerMockito.doNothing().when(StaticClass.class);
StaticClass.method();

The question is already answered, but you can resolve it like this:

File dependency.js

const doSomething = (x) => x
export default doSomething;

File myModule.js

import doSomething from "./dependency";

export default (x) => doSomething(x * 2);

File myModule.spec.js

jest.mock('../dependency');
import doSomething from "../dependency";
import myModule from "../myModule";

describe('myModule', () => {
  it('calls the dependency with double the input', () => {
    doSomething.mockImplementation((x) => x * 10)

    myModule(2);

    expect(doSomething).toHaveBeenCalledWith(4);
    console.log(myModule(2)) // 40
  });
});

For those who want to do this in pure javascript, look at:

Using standard KeyboardEvent

As Joe comment it, KeyboardEvent is now the standard.

Same example to fire an enter (keyCode 13):

const ke = new KeyboardEvent('keydown', {
    bubbles: true, cancelable: true, keyCode: 13
});
document.body.dispatchEvent(ke);

You can use this page help you to find the right keyboard event.

Outdated answer:

• initKeyboardEvent for IE9+, Chrome and Safari
• initKeyEvent for Firefox

You can do something like (here for Firefox)

var ev = document.createEvent('KeyboardEvent');
// Send key '13' (= enter)
ev.initKeyEvent(
    'keydown', true, true, window, false, false, false, false, 13, 0);
document.body.dispatchEvent(ev);

According to docs :

Foo mock = mock(Foo.class, CALLS_REAL_METHODS);

// this calls the real implementation of Foo.getSomething()
value = mock.getSomething();

when(mock.getSomething()).thenReturn(fakeValue);

// now fakeValue is returned
value = mock.getSomething();

Use this permission in manifest file

<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION">

android studio will recommend that "Mock location should only be requested in a test or debug-specific manifest file (typically src/debug/AndroidManifest.xml)" just disable the inspection

Now make sure you have checked the "Allow mock locations" in developer setting of your phone

Use LocationManager

locationManager.addTestProvider(mocLocationProvider, false, false,
                false, false, true, true, true, 0, 5);
locationManager.setTestProviderEnabled(mocLocationProvider, true);

Now set the location wherever you want

Location mockLocation = new Location(mocLocationProvider); 
mockLocation.setLatitude(lat); 
mockLocation.setLongitude(lng); 
mockLocation.setAltitude(alt); 
mockLocation.setTime(System.currentTimeMillis()); 
locationManager.setTestProviderLocation( mocLocationProvider, mockLocation); 

I implemented @user3016183 method using a custom decorator:

def changeNow(func, newNow = datetime(2015, 11, 23, 12, 00, 00)):
    """decorator used to change datetime.datetime.now() in the tested function."""
    def retfunc(self):                             
        with mock.patch('mymodule.datetime') as mock_date:                         
            mock_date.now.return_value = newNow
            mock_date.side_effect = lambda *args, **kw: datetime(*args, **kw)
            func(self)
    return retfunc

I thought that might help someone one day...

I use the first (running the code against a test database). The only substantive issue I see you raising with this approach is the possibilty of schemas getting out of sync, which I deal with by keeping a version number in my database and making all schema changes via a script which applies the changes for each version increment.

I also make all changes (including to the database schema) against my test environment first, so it ends up being the other way around: After all tests pass, apply the schema updates to the production host. I also keep a separate pair of testing vs. application databases on my development system so that I can verify there that the db upgrade works properly before touching the real production box(es).

Instead of window use global

it('correct url is called', () => {
  global.open = jest.fn();
  statementService.openStatementsReport(111);
  expect(global.open).toBeCalled();
});

you could also try

const open = jest.fn()
Object.defineProperty(window, 'open', open);

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

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

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

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

Simplest ways to mock an HttpServletRequest:

1. Create an anonymous subclass:

   HttpServletRequest mock = new HttpServletRequest ()
   {
       private final Map<String, String[]> params = /* whatever */
   
       public Map<String, String[]> getParameterMap()
       {
           return params;
       }
   
       public String getParameter(String name)
       {
           String[] matches = params.get(name);
           if (matches == null || matches.length == 0) return null;
           return matches[0];
       }
   
       // TODO *many* methods to implement here
   };
   

2. Use jMock, Mockito, or some other general-purpose mocking framework:

   HttpServletRequest mock = context.mock(HttpServletRequest.class); // jMock
   HttpServletRequest mock2 = Mockito.mock(HttpServletRequest.class); // Mockito
   

3. Use HttpUnit's ServletUnit and don't mock the request at all.

Key points which explain difference and provide guidance upon working with unittest.mock

1. Use Mock if you want to replace some interface elements(passing args) of the object under test
2. Use patch if you want to replace internal call to some objects and imported modules of the object under test
3. Always provide spec from the object you are mocking
   • With patch you can always provide autospec
   • With Mock you can provide spec
   • Instead of Mock, you can use create_autospec, which intended to create Mock objects with specification.

In the question above the right answer would be to use Mock, or to be more precise create_autospec (because it will add spec to the mock methods of the class you are mocking), the defined spec on the mock will be helpful in case of an attempt to call method of the class which doesn't exists ( regardless signature), please see some

from unittest import TestCase
from unittest.mock import Mock, create_autospec, patch


class MyClass:
    
    @staticmethod
    def method(foo, bar):
        print(foo)


def something(some_class: MyClass):
    arg = 1
    # Would fail becuase of wrong parameters passed to methd.
    return some_class.method(arg)


def second(some_class: MyClass):
    arg = 1
    return some_class.unexisted_method(arg)


class TestSomethingTestCase(TestCase):
    def test_something_with_autospec(self):
        mock = create_autospec(MyClass)
        mock.method.return_value = True
        # Fails because of signature misuse.
        result = something(mock)
        self.assertTrue(result)
        self.assertTrue(mock.method.called)
    
    def test_something(self):
        mock = Mock()  # Note that Mock(spec=MyClass) will also pass, because signatures of mock don't have spec.
        mock.method.return_value = True
        
        result = something(mock)
        
        self.assertTrue(result)
        self.assertTrue(mock.method.called)
        
    def test_second_with_patch_autospec(self):
        with patch(f'{__name__}.MyClass', autospec=True) as mock:
            # Fails because of signature misuse.
            result = second(mock)
        self.assertTrue(result)
        self.assertTrue(mock.unexisted_method.called)


class TestSecondTestCase(TestCase):
    def test_second_with_autospec(self):
        mock = Mock(spec=MyClass)
        # Fails because of signature misuse.
        result = second(mock)
        self.assertTrue(result)
        self.assertTrue(mock.unexisted_method.called)
    
    def test_second_with_patch_autospec(self):
        with patch(f'{__name__}.MyClass', autospec=True) as mock:
            # Fails because of signature misuse.
            result = second(mock)
        self.assertTrue(result)
        self.assertTrue(mock.unexisted_method.called)
    
    def test_second(self):
        mock = Mock()
        mock.unexisted_method.return_value = True
        
        result = second(mock)
        
        self.assertTrue(result)
        self.assertTrue(mock.unexisted_method.called)

The test cases with defined spec used fail because methods called from something and second functions aren't complaint with MyClass, which means - they catch bugs, whereas default Mock will display.

As a side note there is one more option: use patch.object to mock just the class method which is called with.

The good use cases for patch would be the case when the class is used as inner part of function:

def something():
    arg = 1
    return MyClass.method(arg)

Then you will want to use patch as a decorator to mock the MyClass.

You can use a lambda with an input parameter, like so:

.Returns((string myval) => { return myval; });

Or slightly more readable:

.Returns<string>(x => x);

Assuming your test classes are in the same package (under a different source root) as your classes under test you can simply create the mock:

YourClass yourObject = mock(YourClass.class);

and call the methods you want to test just as you would any other method.

You need to provide expectations for each method that is called with the expectation on any concrete methods calling the super method - not sure how you'd do that with Mockito, but I believe it's possible with EasyMock.

All this is doing is creating a concrete instance of YouClass and saving you the effort of providing empty implementations of each abstract method.

As an aside, I often find it useful to implement the abstract class in my test, where it serves as an example implementation that I test via its public interface, although this does depend on the functionality provided by the abstract class.

You can even chain doReturn() method invocations like this

doReturn(null).doReturn(anotherInstance).when(mock).method();

cute isn't it :)

You can use getContentAsString method to get the response data as string.

    String payload = "....";
    String apiToTest = "....";
    
    MvcResult mvcResult = mockMvc.
                perform(post(apiToTest).
                content(payload).
                contentType(MediaType.APPLICATION_JSON)).
                andReturn();
    
    String responseData = mvcResult.getResponse().getContentAsString();

You can refer this link for test application.

If you ever wondered how to do it using the new BDD style of Mockito:

willThrow(new Exception()).given(mockedObject).methodReturningVoid(...));

And for future reference one may need to throw exception and then do nothing:

willThrow(new Exception()).willDoNothing().given(mockedObject).methodReturningVoid(...));

As mentioned in the other answers MOQ cannot mock static methods and, as a general rule, one should avoid statics where possible.

Sometimes it is not possible. One is working with legacy or 3rd party code or with even with the BCL methods that are static.

A possible solution is to wrap the static in a proxy with an interface which can be mocked

    public interface IFileProxy {
        void Delete(string path);
    }

    public class FileProxy : IFileProxy {
        public void Delete(string path) {
            System.IO.File.Delete(path);
        }
    }

    public class MyClass {

        private IFileProxy _fileProxy;

        public MyClass(IFileProxy fileProxy) {
            _fileProxy = fileProxy;
        }

        public void DoSomethingAndDeleteFile(string path) {
            // Do Something with file
            // ...
            // Delete
            System.IO.File.Delete(path);
        }

        public void DoSomethingAndDeleteFileUsingProxy(string path) {
            // Do Something with file
            // ...
            // Delete
            _fileProxy.Delete(path);

        }
    }

The downside is that the ctor can become very cluttered if there are a lot of proxies (though it could be argued that if there are a lot of proxies then the class may be trying to do too much and could be refactored)

Another possibility is to have a 'static proxy' with different implementations of the interface behind it

   public static class FileServices {

        static FileServices() {
            Reset();
        }

        internal static IFileProxy FileProxy { private get; set; }

        public static void Reset(){
           FileProxy = new FileProxy();
        }

        public static void Delete(string path) {
            FileProxy.Delete(path);
        }

    }

Our method now becomes

    public void DoSomethingAndDeleteFileUsingStaticProxy(string path) {
            // Do Something with file
            // ...
            // Delete
            FileServices.Delete(path);

    }

For testing, we can set the FileProxy property to our mock. Using this style reduces the number of interfaces to be injected but makes dependencies a bit less obvious (though no more so than the original static calls I suppose).

Without Using Powermock .... See the example below based on Ben Glasser answer since it took me some time to figure it out ..hope that saves some times ...

Original Class :

public class AClazz {

    public void updateObject(CClazz cClazzObj) {
        log.debug("Bundler set.");
        cClazzObj.setBundler(new BClazz(cClazzObj, 10));
    } 
}

Modified Class :

@Slf4j
public class AClazz {

    public void updateObject(CClazz cClazzObj) {
        log.debug("Bundler set.");
        cClazzObj.setBundler(getBObject(cClazzObj, 10));
    }

    protected BClazz getBObject(CClazz cClazzObj, int i) {
        return new BClazz(cClazzObj, 10);
    }
 }

Test Class

public class AClazzTest {

    @InjectMocks
    @Spy
    private AClazz aClazzObj;

    @Mock
    private CClazz cClazzObj;

    @Mock
    private BClazz bClassObj;

    @Before
    public void setUp() throws Exception {
        Mockito.doReturn(bClassObj)
               .when(aClazzObj)
               .getBObject(Mockito.eq(cClazzObj), Mockito.anyInt());
    }

    @Test
    public void testConfigStrategy() {
        aClazzObj.updateObject(cClazzObj);

        Mockito.verify(cClazzObj, Mockito.times(1)).setBundler(bClassObj);
    }
}

First you need to create a mock m_contractsDao and set it up. Assuming that the class is ContractsDao:

ContractsDao mock_contractsDao = mock(ContractsDao.class);
when(mock_contractsDao.save(any(String.class))).thenReturn("Some result");

Then inject the mock into m_orderSvc and call your method.

m_orderSvc.m_contractsDao = mock_contractsDao;
m_prog = new ProcessOrdersWorker(m_orderSvc, m_opportunitySvc, m_myprojectOrgSvc);
m_prog.work(); 

Finally, verify that the mock was called properly:

verify(mock_contractsDao, times(1)).save("Parameter I'm expecting");

First of all: you should always import mockito static, this way the code will be much more readable (and intuitive):

import static org.mockito.Mockito.*;

For partial mocking and still keeping original functionality on the rest mockito offers "Spy".

You can use it as follows:

private World world = spy(new World());

To eliminate a method from being executed you could use something like this:

doNothing().when(someObject).someMethod(anyObject());

to give some custom behaviour to a method use "when" with an "thenReturn":

doReturn("something").when(this.world).someMethod(anyObject());

For more examples please find the excellent mockito samples in the doc.

One more possibility, if you don't want to use ArgumentCaptor (for example, because you're also using stubbing), is to use Hamcrest Matchers in combination with Mockito.

import org.mockito.Mockito
import org.hamcrest.Matchers
...

Mockito.verify(mockedObject).someMethodOnMockedObject(MockitoHamcrest.argThat(
    Matchers.<SomeObjectAsArgument>hasProperty("propertyName", desiredValue)));

I will add this information since I had a hard time figuring how to mock an async api call.

Here is what I did to mock an async call.

Here is the function I wanted to test

async def get_user_info(headers, payload):
    return await httpx.AsyncClient().post(URI, json=payload, headers=headers)

You still need the MockResponse class

class MockResponse:
    def __init__(self, json_data, status_code):
        self.json_data = json_data
        self.status_code = status_code

    def json(self):
        return self.json_data

You add the MockResponseAsync class

class MockResponseAsync:
    def __init__(self, json_data, status_code):
        self.response = MockResponse(json_data, status_code)

    async def getResponse(self):
        return self.response

Here is the test. The important thing here is I create the response before since init function can't be async and the call to getResponse is async so it all checked out.

@pytest.mark.asyncio
@patch('httpx.AsyncClient')
async def test_get_user_info_valid(self, mock_post):
    """test_get_user_info_valid"""
    # Given
    token_bd = "abc"
    username = "bob"
    payload = {
        'USERNAME': username,
        'DBNAME': 'TEST'
    }
    headers = {
        'Authorization': 'Bearer ' + token_bd,
        'Content-Type': 'application/json'
    }
    async_response = MockResponseAsync("", 200)
    mock_post.return_value.post.return_value = async_response.getResponse()

    # When
    await api_bd.get_user_info(headers, payload)

    # Then
    mock_post.return_value.post.assert_called_once_with(
        URI, json=payload, headers=headers)

If you have a better way of doing that tell me but I think it's pretty clean like that.

[Test double types]

Mock vs Spy

Mock is a bare double object. This object has the same methods signatures but realisation is empty and return default value - 0 and null

Spy is a cloned double object. New object is cloned based on a real object but you have a possibility to mock it

class A {
    String foo1() {
        foo2();
        return "RealString_1";
    }

    String foo2() {
        return "RealString_2";
    }

    void foo3() { foo4(); }

    void foo4() { }
}

@Test
public void testMockA() {
    //given
    A mockA = Mockito.mock(A.class);
    Mockito.when(mockA.foo1()).thenReturn("MockedString");

    //when
    String result1 = mockA.foo1();
    String result2 = mockA.foo2();

    //then
    assertEquals("MockedString", result1);
    assertEquals(null, result2);

    //Case 2
    //when
    mockA.foo3();

    //then
    verify(mockA).foo3();
    verify(mockA, never()).foo4();
}

@Test
public void testSpyA() {
    //given
    A spyA = Mockito.spy(new A());

    Mockito.when(spyA.foo1()).thenReturn("MockedString");

    //when
    String result1 = spyA.foo1();
    String result2 = spyA.foo2();

    //then
    assertEquals("MockedString", result1);
    assertEquals("RealString_2", result2);

    //Case 2
    //when
    spyA.foo3();

    //then
    verify(spyA).foo3();
    verify(spyA).foo4();
}

HttpContext.Current returns an instance of System.Web.HttpContext, which does not extend System.Web.HttpContextBase. HttpContextBase was added later to address HttpContext being difficult to mock. The two classes are basically unrelated (HttpContextWrapper is used as an adapter between them).

Fortunately, HttpContext itself is fakeable just enough for you do replace the IPrincipal (User) and IIdentity.

The following code runs as expected, even in a console application:

HttpContext.Current = new HttpContext(
    new HttpRequest("", "http://tempuri.org", ""),
    new HttpResponse(new StringWriter())
    );

// User is logged in
HttpContext.Current.User = new GenericPrincipal(
    new GenericIdentity("username"),
    new string[0]
    );

// User is logged out
HttpContext.Current.User = new GenericPrincipal(
    new GenericIdentity(String.Empty),
    new string[0]
    );

To mock static method you should use a Powermock look at: https://github.com/powermock/powermock/wiki/MockStatic. Mockito doesn't provide this functionality.

You can read nice a article about mockito: http://refcardz.dzone.com/refcardz/mockito

There are plenty of answers on SO and good posts on the web about mocking. One place that you might want to start looking is the post by Martin Fowler Mocks Aren't Stubs where he discusses a lot of the ideas of mocking.

In one paragraph - Mocking is one particlar technique to allow testing of a unit of code with out being reliant upon dependencies. In general, what differentiates mocking from other methods is that mock objects used to replace code dependencies will allow expectations to be set - a mock object will know how it is meant to be called by your code and how to respond.

Your original question mentioned TypeMock, so I've left my answer to that below:

TypeMock is the name of a commercial mocking framework.

It offers all the features of the free mocking frameworks like RhinoMocks and Moq, plus some more powerful options.

Whether or not you need TypeMock is highly debatable - you can do most mocking you would ever want with free mocking libraries, and many argue that the abilities offered by TypeMock will often lead you away from well encapsulated design.

As another answer stated 'TypeMocking' is not actually a defined concept, but could be taken to mean the type of mocking that TypeMock offers, using the CLR profiler to intercept .Net calls at runtime, giving much greater ability to fake objects (not requirements such as needing interfaces or virtual methods).

If you "want to return a fixed value when the input parameter has a particular value", maybe you don't even need a mock and could use a dict along with its get method:

foo = {'input1': 'value1', 'input2': 'value2'}.get

foo('input1')  # value1
foo('input2')  # value2

This works well when your fake's output is a mapping of input. When it's a function of input I'd suggest using side_effect as per Amber's answer.

You can also use a combination of both if you want to preserve Mock's capabilities (assert_called_once, call_count etc):

self.mock.side_effect = {'input1': 'value1', 'input2': 'value2'}.get

OK, this is a bad thing to be doing. Don't mock a list; instead, mock the individual objects inside the list. See Mockito: mocking an arraylist that will be looped in a for loop for how to do this.

Also, why are you using PowerMock? You don't seem to be doing anything that requires PowerMock.

But the real cause of your problem is that you are using when on two different objects, before you complete the stubbing. When you call when, and provide the method call that you are trying to stub, then the very next thing you do in either Mockito OR PowerMock is to specify what happens when that method is called - that is, to do the thenReturn part. Each call to when must be followed by one and only one call to thenReturn, before you do any more calls to when. You made two calls to when without calling thenReturn - that's your error.

You've nearly got it. The problem is that the Class Under Test (CUT) is not built for unit testing - it has not really been TDD'd.

Think of it like this…

• I need to test a function of a class - let's call it myFunction
• That function makes a call to a function on another class/service/database
• That function also calls another method on the CUT

In the unit test

• Should create a concrete CUT or @Spy on it
• You can @Mock all of the other class/service/database (i.e. external dependencies)
• You could stub the other function called in the CUT but it is not really how unit testing should be done

In order to avoid executing code that you are not strictly testing, you could abstract that code away into something that can be @Mocked.

In this very simple example, a function that creates an object will be difficult to test

public void doSomethingCool(String foo) {
    MyObject obj = new MyObject(foo);

    // can't do much with obj in a unit test unless it is returned
}

But a function that uses a service to get MyObject is easy to test, as we have abstracted the difficult/impossible to test code into something that makes this method testable.

public void doSomethingCool(String foo) {
    MyObject obj = MyObjectService.getMeAnObject(foo);
}

as MyObjectService can be mocked and also verified that .getMeAnObject() is called with the foo variable.

As I needed to use this feature for my latest project (at one point we updated from 1.10.19), just to keep the users (that are already using the mockito-core version 2.1.0 or greater) up to date, the static methods from the above answers should be taken from ArgumentMatchers class:

import static org.mockito.ArgumentMatchers.isA;
import static org.mockito.ArgumentMatchers.any;

Please keep this in mind if you are planning to keep your Mockito artefacts up to date as possibly starting from version 3, this class may no longer exist:

As per 2.1.0 and above, Javadoc of org.mockito.Matchers states:

Use org.mockito.ArgumentMatchers. This class is now deprecated in order to avoid a name clash with Hamcrest * org.hamcrest.Matchers class. This class will likely be removed in version 3.0.

I have written a little article on mockito wildcards if you're up for further reading.

To illustrate the usage of stubs and mocks, I would like to also include an example based on Roy Osherove's "The Art of Unit Testing".

Imagine, we have a LogAnalyzer application which has the sole functionality of printing logs. It not only needs to talk to a web service, but if the web service throws an error, LogAnalyzer has to log the error to a different external dependency, sending it by email to the web service administrator.

Here’s the logic we’d like to test inside LogAnalyzer:

if(fileName.Length<8)
{
 try
  {
    service.LogError("Filename too short:" + fileName);
  }
 catch (Exception e)
  {
    email.SendEmail("a","subject",e.Message);
  }
}

How do you test that LogAnalyzer calls the email service correctly when the web service throws an exception? Here are the questions we’re faced with:

• How can we replace the web service?

• How can we simulate an exception from the web service so that we can test the call to the email service?

• How will we know that the email service was called correctly or at all?

We can deal with the first two questions by using a stub for the web service. To solve the third problem, we can use a mock object for the email service.

A fake is a generic term that can be used to describe either a stub or a mock.In our test, we’ll have two fakes. One will be the email service mock, which we’ll use to verify that the correct parameters were sent to the email service. The other will be a stub that we’ll use to simulate an exception thrown from the web service. It’s a stub because we won’t be using the web service fake to verify the test result, only to make sure the test runs correctly. The email service is a mock because we’ll assert against it that it was called correctly.

[TestFixture]
public class LogAnalyzer2Tests
{
[Test]
 public void Analyze_WebServiceThrows_SendsEmail()
 {
   StubService stubService = new StubService();
   stubService.ToThrow= new Exception("fake exception");
   MockEmailService mockEmail = new MockEmailService();

   LogAnalyzer2 log = new LogAnalyzer2();
   log.Service = stubService
   log.Email=mockEmail;
   string tooShortFileName="abc.ext";
   log.Analyze(tooShortFileName);

   Assert.AreEqual("a",mockEmail.To); //MOCKING USED
   Assert.AreEqual("fake exception",mockEmail.Body); //MOCKING USED
   Assert.AreEqual("subject",mockEmail.Subject);
 }
}

A "mocking framework", which Mockito is based on, is a framework that gives you the ability to create Mock objects ( in old terms these objects could be called shunts, as they work as shunts for dependend functionality ) In other words, a mock object is used to imitate the real object your code is dependend on, you create a proxy object with the mocking framework. By using mock objects in your tests you are essentially going from normal unit testing to integrational testing

Mockito is an open source testing framework for Java released under the MIT License, it is a "mocking framework", that lets you write beautiful tests with clean and simple API. There are many different mocking frameworks in the Java space, however there are essentially two main types of mock object frameworks, ones that are implemented via proxy and ones that are implemented via class remapping.

Dependency injection frameworks like Spring allow you to inject your proxy objects without modifying any code, the mock object expects a certain method to be called and it will return an expected result.

The @InjectMocks annotation tries to instantiate the testing object instance and injects fields annotated with @Mock or @Spy into private fields of the testing object.

MockitoAnnotations.initMocks(this) call, resets testing object and re-initializes mocks, so remember to have this at your @Before / @BeforeMethod annotation.

Judging from other answers, no one except @rob-kennedy talked about the call_args_list.

It's a powerful tool for that you can implement the exact contrary of MagicMock.assert_called_with()

call_args_list is a list of call objects. Each call object represents a call made on a mocked callable.

>>> from unittest.mock import MagicMock
>>> m = MagicMock()
>>> m.call_args_list
[]
>>> m(42)
<MagicMock name='mock()' id='139675158423872'>
>>> m.call_args_list
[call(42)]
>>> m(42, 30)
<MagicMock name='mock()' id='139675158423872'>
>>> m.call_args_list
[call(42), call(42, 30)]

Consuming a call object is easy, since you can compare it with a tuple of length 2 where the first component is a tuple containing all the positional arguments of the related call, while the second component is a dictionary of the keyword arguments.

>>> ((42,),) in m.call_args_list
True
>>> m(42, foo='bar')
<MagicMock name='mock()' id='139675158423872'>
>>> ((42,), {'foo': 'bar'}) in m.call_args_list
True
>>> m(foo='bar')
<MagicMock name='mock()' id='139675158423872'>
>>> ((), {'foo': 'bar'}) in m.call_args_list
True

So, a way to address the specific problem of the OP is

def test_something():
    with patch('something') as my_var:
        assert ((some, args),) not in my_var.call_args_list

Note that this way, instead of just checking if a mocked callable has been called, via MagicMock.called, you can now check if it has been called with a specific set of arguments.

That's useful. Say you want to test a function that takes a list and call another function, compute(), for each of the value of the list only if they satisfy a specific condition.

You can now mock compute, and test if it has been called on some value but not on others.

Check the Java API for List.
The get(int index) method is declared to throw only the IndexOutOfBoundException which extends RuntimeException.
You are trying to tell Mockito to throw an exception SomeException() that is not valid to be thrown by that particular method call.

To clarify further.
The List interface does not provide for a checked Exception to be thrown from the get(int index) method and that is why Mockito is failing.
When you create the mocked List, Mockito will use the definition of List.class to creates its mock.

The behavior you are specifying with the when(list.get(0)).thenThrow(new SomeException()) doesn't match the method signature in List API, because get(int index) method does not throw SomeException() so Mockito fails.

If you really want to do this, then have Mockito throw a new RuntimeException() or even better throw a new ArrayIndexOutOfBoundsException() since the API specifies that that is the only valid Exception to be thrown.

I know this is an old post, but in case someone else happens upon this question, one good option is Virtual Serial Port Emulator (VSPE) from Eterlogic It provides an API for creating kernel mode virtual comport devices, i.e. connectors, mappers, splitters etc.
However, some of the advertised capabilities were really not capabilities at all.

A much better choice, Eltima. This product is fully baked. Good developer tech support. The product did all it claimed to do. Product options include both desktop applications, as well as software development kits with APIs.

Neither of these products are open source, or free. However, as other posts here have pointed out, there are other options. Here is a list of various serial utilities:

when(
  fooDao.getBar(
    any(Bazoo.class)
  )
).thenReturn(myFoo);

or (to avoid nulls):

when(
  fooDao.getBar(
    (Bazoo)notNull()
  )
).thenReturn(myFoo);

Don't forget to import matchers (many others are available):

For Mockito 2.1.0 and newer:

import static org.mockito.ArgumentMatchers.*;

For older versions:

import static org.mockito.Matchers.*;

org.mockito.exceptions.misusing.UnfinishedStubbingException: 
Unfinished stubbing detected here:
E.g. thenReturn() may be missing.

For mocking of void methods try out below:

//Kotlin Syntax

 Mockito.`when`(voidMethodCall())
           .then {
                Unit //Do Nothing
            }

Or, even cleaner:

when(mockFoo.someMethod()).thenReturn(obj1, obj2);

Just a small addition to Jeff Bowman's excellent answer, as I found this question when searching for a solution to one of my own problems:

If a call to a method matches more than one mock's when trained calls, the order of the when calls is important, and should be from the most wider to the most specific. Starting from one of Jeff's examples:

when(foo.quux(anyInt(), anyInt())).thenReturn(true);
when(foo.quux(anyInt(), eq(5))).thenReturn(false);

is the order that ensures the (probably) desired result:

foo.quux(3 /*any int*/, 8 /*any other int than 5*/) //returns true
foo.quux(2 /*any int*/, 5) //returns false

If you inverse the when calls then the result would always be true.

You can assign an iterable to side_effect, and the mock will return the next value in the sequence each time it is called:

>>> from unittest.mock import Mock
>>> m = Mock()
>>> m.side_effect = ['foo', 'bar', 'baz']
>>> m()
'foo'
>>> m()
'bar'
>>> m()
'baz'

Quoting the Mock() documentation:

If side_effect is an iterable then each call to the mock will return the next value from the iterable.

I'm using a slightly different approach where public struct methods implement interfaces but their logic is limited to just wrapping private (unexported) functions which take those interfaces as parameters. This gives you the granularity you would need to mock virtually any dependency and yet have a clean API to use from outside your test suite.

To understand this it is imperative to understand that you have access to the unexported methods in your test case (i.e. from within your _test.go files) so you test those instead of testing the exported ones which have no logic inside beside wrapping.

To summarize: test the unexported functions instead of testing the exported ones!

Let's make an example. Say that we have a Slack API struct which has two methods:

• the SendMessage method which sends an HTTP request to a Slack webhook
• the SendDataSynchronously method which given a slice of strings iterates over them and calls SendMessage for every iteration

So in order to test SendDataSynchronously without making an HTTP request each time we would have to mock SendMessage, right?

package main

import (
    "fmt"
)

// URI interface
type URI interface {
    GetURL() string
}

// MessageSender interface
type MessageSender interface {
    SendMessage(message string) error
}

// This one is the "object" that our users will call to use this package functionalities
type API struct {
    baseURL  string
    endpoint string
}

// Here we make API implement implicitly the URI interface
func (api *API) GetURL() string {
    return api.baseURL + api.endpoint
}

// Here we make API implement implicitly the MessageSender interface
// Again we're just WRAPPING the sendMessage function here, nothing fancy 
func (api *API) SendMessage(message string) error {
    return sendMessage(api, message)
}

// We want to test this method but it calls SendMessage which makes a real HTTP request!
// Again we're just WRAPPING the sendDataSynchronously function here, nothing fancy
func (api *API) SendDataSynchronously(data []string) error {
    return sendDataSynchronously(api, data)
}

// this would make a real HTTP request
func sendMessage(uri URI, message string) error {
    fmt.Println("This function won't get called because we will mock it")
    return nil
}

// this is the function we want to test :)
func sendDataSynchronously(sender MessageSender, data []string) error {
    for _, text := range data {
        err := sender.SendMessage(text)

        if err != nil {
            return err
        }
    }

    return nil
}

// TEST CASE BELOW

// Here's our mock which just contains some variables that will be filled for running assertions on them later on
type mockedSender struct {
    err      error
    messages []string
}

// We make our mock implement the MessageSender interface so we can test sendDataSynchronously
func (sender *mockedSender) SendMessage(message string) error {
    // let's store all received messages for later assertions
    sender.messages = append(sender.messages, message)

    return sender.err // return error for later assertions
}

func TestSendsAllMessagesSynchronously() {
    mockedMessages := make([]string, 0)
    sender := mockedSender{nil, mockedMessages}

    messagesToSend := []string{"one", "two", "three"}
    err := sendDataSynchronously(&sender, messagesToSend)

    if err == nil {
        fmt.Println("All good here we expect the error to be nil:", err)
    }

    expectedMessages := fmt.Sprintf("%v", messagesToSend)
    actualMessages := fmt.Sprintf("%v", sender.messages)

    if expectedMessages == actualMessages {
        fmt.Println("Actual messages are as expected:", actualMessages)
    }
}

func main() {
    TestSendsAllMessagesSynchronously()
}

What I like about this approach is that by looking at the unexported methods you can clearly see what the dependencies are. At the same time the API that you export is a lot cleaner and with less parameters to pass along since the true dependency here is just the parent receiver which is implementing all those interfaces itself. Yet every function is potentially depending only on one part of it (one, maybe two interfaces) which makes refactors a lot easier. It's nice to see how your code is really coupled just by looking at the functions signatures, I think it makes a powerful tool against smelling code.

To make things easy I put everything into one file to allow you to run the code in the playground here but I suggest you also check out the full example on GitHub, here is the slack.go file and here the slack_test.go.

And here the whole thing.

This is how I managed to do what I was trying to do:

[Test]
public void TransferHandlesDisconnect()
{
    // ... set up config here
    var methodTester = new Mock<Transfer>(configInfo);
    methodTester.CallBase = true;
    methodTester
        .Setup(m => 
            m.GetFile(
                It.IsAny<IFileConnection>(), 
                It.IsAny<string>(), 
                It.IsAny<string>()
            ))
        .Throws<System.IO.IOException>();

    methodTester.Object.TransferFiles("foo1", "foo2");
    Assert.IsTrue(methodTester.Object.Status == TransferStatus.TransferInterrupted);
}

If there is a problem with this method, I would like to know; the other answers suggest I am doing this wrong, but this was exactly what I was trying to do.

If you are using ES6 (Babel) or TypeScript you can stub out the property using get and set accessors

export class SomeClassStub {
  getValueA = jasmine.createSpy('getValueA');
  setValueA = jasmine.createSpy('setValueA');
  get valueA() { return this.getValueA(); }
  set valueA(value) { this.setValueA(value); }
}

Then in your test you can check that the property is set with:

stub.valueA = 'foo';

expect(stub.setValueA).toHaveBeenCalledWith('foo');

using sinon :

const mockAction = sinon.stub(MyService.prototype,'actionBeingCalled')
                     .returns(httpPromise(200));

Known that, httpPromise can be :

const httpPromise = (code) => new Promise((resolve, reject) =>
  (code >= 200 && code <= 299) ? resolve({ code }) : reject({ code, error:true })
);

You can also use @Captor annotated ArgumentCaptor. For example:

@Mock
List<String> mockedList;

@Captor
ArgumentCaptor<String> argCaptor;

@BeforeTest
public void init() {
    //Initialize objects annotated with @Mock, @Captor and @Spy.
    MockitoAnnotations.initMocks(this);
}

@Test
public void shouldCallAddMethodTwice() {
    mockedList.add("one");
    mockedList.add("two");
    Mockito.verify(mockedList, times(2)).add(argCaptor.capture());

    assertEquals("one", argCaptor.getAllValues().get(0));
    assertEquals("two", argCaptor.getAllValues().get(1));
}

We are heavily using EasyMock and EasyMock Class Extension at work and are pretty happy with it. It basically gives you everything you need. Take a look at the documentation, there's a very nice example which shows you all the features of EasyMock.

The standard mocking frameworks are creating proxy classes. This is the reason why they are technically limited to interfaces and virtual methods.

If you want to mock 'normal' methods as well, you need a tool that works with instrumentation instead of proxy generation. E.g. MS Moles and Typemock can do that. But the former has a horrible 'API', and the latter is commercial.

Yes, this can be done, as the following test shows (written with the JMockit mocking API, which I develop):

@Test
public void testFirst(@Mocked final Second sec) {
    new NonStrictExpectations() {{ sec.doSecond(); result = "Stubbed Second"; }};

    First first = new First();
    assertEquals("Stubbed Second", first.doSecond());
}

With Mockito, however, such a test cannot be written. This is due to the way mocking is implemented in Mockito, where a subclass of the class to be mocked is created; only instances of this "mock" subclass can have mocked behavior, so you need to have the tested code use them instead of any other instance.

This can be done with something like this:

# foo.py
class Foo:
    def method_1():
        results = uses_some_other_method()


# testing.py
from mock import patch

@patch('Foo.uses_some_other_method', return_value="specific_value"):
def test_some_other_method(mock_some_other_method):
    foo = Foo()
    the_value = foo.method_1()
    assert the_value == "specific_value"

Here's a source that you can read: Patching in the wrong place

To patch the built-in open() function with unittest:

This worked for a patch to read a json config.

class ObjectUnderTest:
    def __init__(self, filename: str):
        with open(filename, 'r') as f:
            dict_content = json.load(f)

The mocked object is the io.TextIOWrapper object returned by the open() function

@patch("<src.where.object.is.used>.open",
        return_value=io.TextIOWrapper(io.BufferedReader(io.BytesIO(b'{"test_key": "test_value"}'))))
    def test_object_function_under_test(self, mocker):

You can use the Mock.call_args_list attribute to compare parameters to previous method calls. That in conjunction with Mock.call_count attribute should give you full control.

you can use your method by this way

var app = 'AirFare';
var d1 = new Date();
var d2 = new Date();

$http({
    url: '/api/apiControllerName/methodName',
    method: 'POST',
    params: {application:app, from:d1, to:d2},
    headers: { 'Content-Type': 'application/json;charset=utf-8' },
    //timeout: 1,
    //cache: false,
    //transformRequest: false,
    //transformResponse: false
}).then(function (results) {
    return results;
}).catch(function (e) {

});

if min=10 and max=100:

(int)(Math.random() * max) + min        

gives a result between 10 and 110, while

(int)(Math.random() * (max - min) + min)

gives a result between 10 and 100, so they are very different formulas. What's important here is clarity, so whatever you do, make sure the code makes it clear what is being generated.

(PS. the first makes more sense if you change the variable 'max' to be called 'range')

$('#form').append('<input type="text" value="'+yourValue+'" />');

You don't need to compile header files. It doesn't actually do anything, so there's no point in trying to run it. However, it is a great way to check for typos and mistakes and bugs, so it'll be easier later.

The CBO builds a decision tree, estimating the costs of each possible execution path available per query. The costs are set by the CPU_cost or I/O_cost parameter set on the instance. And the CBO estimates the costs, as best it can with the existing statistics of the tables and indexes that the query will use. You should not tune your query based on cost alone. Cost allows you to understand WHY the optimizer is doing what it does. Without cost you could figure out why the optimizer chose the plan it did. Lower cost does not mean a faster query. There are cases where this is true and there will be cases where this is wrong. Cost is based on your table stats and if they are wrong the cost is going to be wrong.

When tuning your query, you should take a look at the cardinality and the number of rows of each step. Do they make sense? Is the cardinality the optimizer is assuming correct? Is the rows being return reasonable. If the information present is wrong then its very likely the optimizer doesn't have the proper information it needs to make the right decision. This could be due to stale or missing statistics on the table and index as well as cpu-stats. Its best to have stats updated when tuning a query to get the most out of the optimizer. Knowing your schema is also of great help when tuning. Knowing when the optimizer chose a really bad decision and pointing it in the correct path with a small hint can save a load of time.

1st: If you know that your code isn't right, you should fix it before do anything!

You could do something like this:

function validateForm() {
    var radios = document.getElementsByName("yesno");
    var formValid = false;

    var i = 0;
    while (!formValid && i < radios.length) {
        if (radios[i].checked) formValid = true;
        i++;        
    }

    if (!formValid) alert("Must check some option!");
    return formValid;
}?

If you are interested in finding any file type by their magic bytes using the awesome file utility combined with power of find, this can come in handy:

$ # Let's make some test files
$ mkdir ASCII-finder
$ cd ASCII-finder
$ dd if=/dev/urandom of=binary.file bs=1M count=1
1+0 records in
1+0 records out
1048576 bytes (1.0 MB, 1.0 MiB) copied, 0.009023 s, 116 MB/s
$ file binary.file
binary.file: data
$ echo 123 > text.txt
$ # Let the magic begin
$ find -type f -print0 | \
    xargs -0 -I @@ bash -c 'file "$@" | grep ASCII &>/dev/null && echo "file is ASCII: $@"' -- @@

Output:

file is ASCII: ./text.txt

Legend: $ is the interactive shell prompt where we enter our commands

You can modify the part after && to call some other script or do some other stuff inline as well, i.e. if that file contains given string, cat the entire file or look for a secondary string in it.

Explanation:

• find items that are files
• Make xargs feed each item as a line into one liner bash command/script
• file checks type of file by magic byte, grep checks if ASCII exists, if so, then after && your next command executes.
• find prints results null separated, this is good to escape filenames with spaces and meta-characters in it.
• xargs , using -0 option, reads them null separated, -I @@ takes each record and uses as positional parameter/args to bash script.
• -- for bash ensures whatever comes after it is an argument even if it starts with - like -c which could otherwise be interpreted as bash option

If you need to find types other than ASCII, simply replace grep ASCII with other type, like grep "PDF document, version 1.4"

try

Sub save()
ActiveWorkbook.SaveAS Filename:="C:\-docs\cmat\Desktop\New folder\" & Range("C5").Text & chr(32) & Range("C8").Text &".xls", FileFormat:= _
  xlNormal, Password:="", WriteResPassword:="", ReadOnlyRecommended:=False _
 , CreateBackup:=False
End Sub

If you want to save the workbook with the macros use the below code

Sub save()
ActiveWorkbook.SaveAs Filename:="C:\Users\" & Environ$("username") & _
    "\Desktop\" & Range("C5").Text & Chr(32) & Range("C8").Text & ".xlsm", FileFormat:= _
    xlOpenXMLWorkbookMacroEnabled, Password:=vbNullString, WriteResPassword:=vbNullString, _
    ReadOnlyRecommended:=False, CreateBackup:=False
End Sub

if you want to save workbook with no macros and no pop-up use this

Sub save()
    Application.DisplayAlerts = False
    ActiveWorkbook.SaveAs Filename:="C:\Users\" & Environ$("username") & _
    "\Desktop\" & Range("C5").Text & Chr(32) & Range("C8").Text & ".xls", _
    FileFormat:=xlOpenXMLWorkbook, CreateBackup:=False
    Application.DisplayAlerts = True
End Sub

Similar to @Matthew_Plourde using gsub

However, using a pattern that will trim to zero characters i.e. return "" if the original string is shorter than the number of characters to cut:

cs <- c("foo_bar","bar_foo","apple","beer","so","a")
gsub('.{0,3}$', '', cs)
# [1] "foo_" "bar_" "ap"   "b"    ""    ""

Difference is, {0,3} quantifier indicates 0 to 3 matches, whereas {3} requires exactly 3 matches otherwise no match is found in which case gsub returns the original, unmodified string.

N.B. using {,3} would be equivalent to {0,3}, I simply prefer the latter notation.

See here for more information on regex quantifiers: https://www.regular-expressions.info/refrepeat.html

For regex, I first look at this web site: RegExLib.com

You're looking for the OpenFileDialog class.

For example:

Sub SomeButton_Click(sender As Object, e As EventArgs) Handles SomeButton.Click
    Using dialog As New OpenFileDialog
        If dialog.ShowDialog() <> DialogResult.OK Then Return
        File.Copy(dialog.FileName, newPath)
    End Using
End Sub

You should always avoid using system() because

• It is resource heavy
• It defeats security -- you don't know you it's a valid command or does the same thing on every system, you could even start up programs you didn't intend to start up. The danger is that when you directly execute a program, it gets the same privileges as your program -- meaning that if, for example, you are running as system administrator then the malicious program you just inadvertently executed is also running as system administrator. If that doesn't scare you silly, check your pulse.
• Anti virus programs hate it, your program could get flagged as a virus.

You should use CreateProcess().

You can use Createprocess() to just start up an .exe and creating a new process for it. The application will run independent from the calling application.

Here's an example I used in one of my projects:

#include <windows.h>

VOID startup(LPCTSTR lpApplicationName)
{
   // additional information
   STARTUPINFO si;     
   PROCESS_INFORMATION pi;

   // set the size of the structures
   ZeroMemory( &si, sizeof(si) );
   si.cb = sizeof(si);
   ZeroMemory( &pi, sizeof(pi) );

  // start the program up
  CreateProcess( lpApplicationName,   // the path
    argv[1],        // Command line
    NULL,           // Process handle not inheritable
    NULL,           // Thread handle not inheritable
    FALSE,          // Set handle inheritance to FALSE
    0,              // No creation flags
    NULL,           // Use parent's environment block
    NULL,           // Use parent's starting directory 
    &si,            // Pointer to STARTUPINFO structure
    &pi             // Pointer to PROCESS_INFORMATION structure (removed extra parentheses)
    );
    // Close process and thread handles. 
    CloseHandle( pi.hProcess );
    CloseHandle( pi.hThread );
}

EDIT: The error you are getting is because you need to specify the path of the .exe file not just the name. Openfile.exe probably doesn't exist.

Here's working example with anonymous output record, if you have any questions place a comment below:                    

public partial class Form1 : Form
{
    DataTable table;
    public Form1()
    {
        InitializeComponent();
        #region TestData
        table = new DataTable();
        table.Clear();
        for (int i = 1; i < 12; ++i)
            table.Columns.Add("Col" + i);
        for (int rowIndex = 0; rowIndex < 5; ++rowIndex)
        {
            DataRow row = table.NewRow();
            for (int i = 0; i < table.Columns.Count; ++i)
                row[i] = String.Format("row:{0},col:{1}", rowIndex, i);
            table.Rows.Add(row);
        }
        #endregion
        bind();
    }

    public void bind()
    {
        var filtered = from t in table.AsEnumerable()
                       select new
                       {
                           col1 = t.Field<string>(0),//column of index 0 = "Col1"
                           col2 = t.Field<string>(1),//column of index 1 = "Col2"

                       };

Use sp_rename:

EXEC sp_rename 'Stu_Table', 'Stu_Table_10'

You can find documentation on this procedure on MSDN.

If you need to include a schema name, this can only be included in the first parameter (that is, this cannot be used to move a table from one schema to another). So, for example, this is valid:

EXEC sp_rename 'myschema.Stu_Table', 'Stu_Table_10'

My hint:

1. FIND IF EXISTS in .env:

   APP_URL=http://yourhost.dev

2. REPLACE TO (OR ADD)

   APP_DOMAIN=yourhost.dev

3. FIND in config/app.php:

   'url' => env('APP_URL'),

4. REPLACE TO

   'domain' => env('APP_DOMAIN'),

   'url' => 'http://' . env('APP_DOMAIN'),

5. USE:

   Config::get('app.domain'); // yourhost.dev

   Config::get('app.url') // http://yourhost.dev

6. Do your magic!

Well, you're on the right path, Benno!

There are some tips regarding VBA programming that might help you out.

1. Use always explicit references to the sheet you want to interact with. Otherwise, Excel may 'assume' your code applies to the active sheet and eventually you'll see it screws your spreadsheet up.

2. As lionz mentioned, get in touch with the native methods Excel offers. You might use them on most of your tricks.

3. Explicitly declare your variables... they'll show the list of methods each object offers in VBA. It might save your time digging on the internet.

Now, let's have a draft code...

Remember this code must be within the Excel Sheet object, as explained by lionz. It only applies to Sheet 2, is up to you to adapt it to both Sheet 2 and Sheet 3 in the way you prefer.

Hope it helps!

Private Sub Worksheet_Change(ByVal Target As Range)

    Dim oSheet As Excel.Worksheet

    'We only want to do something if the changed cell is B6, right?
    If Target.Address = "$B$6" Then

        'Checks if it's a number...
        If IsNumeric(Target.Value) Then

            'Let's avoid values out of your bonds, correct?
            If Target.Value > 0 And Target.Value < 51 Then

                'Let's assign the worksheet we'll show / hide rows to one variable and then
                '   use only the reference to the variable itself instead of the sheet name.
                '   It's safer.

                'You can alternatively replace 'sheet 2' by 2 (without quotes) which will represent
                '   the sheet index within the workbook
                Set oSheet = ActiveWorkbook.Sheets("Sheet 2")

                'We'll unhide before hide, to ensure we hide the correct ones
                oSheet.Range("A7:A56").EntireRow.Hidden = False

                oSheet.Range("A" & Target.Value + 7 & ":A56").EntireRow.Hidden = True

            End If

        End If

    End If

End Sub

try this declare the function outside the ready event.

    $(document).ready(function(){    
       setInterval(swapImages(),1000); 
    });


    function swapImages(){

    var active = $('.active'); 
    var next = ($('.active').next().length > 0) ? $('.active').next() :         $('#siteNewsHead img:first');
    active.removeClass('active');
    next.addClass('active');
}

Which specific index? If you want 'Add New' to be first on the dropdownlist you can add it though the code like this:

<asp:DropDownList ID="DropDownList1" AppendDataBoundItems="true" runat="server">
     <asp:ListItem Text="Add New" Value="0" />
</asp:DropDownList>

If you want to add it at a different index, maybe the last then try:

ListItem lst = new ListItem ( "Add New" , "0" );

DropDownList1.Items.Insert( DropDownList1.Items.Count-1 ,lst);

You can change location of legend using loc argument. https://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.legend

import matplotlib.pyplot as plt

plt.subplot(211)
plt.plot([1,2,3], label="test1")
plt.plot([3,2,1], label="test2")
# Place a legend above this subplot, expanding itself to
# fully use the given bounding box.
plt.legend(bbox_to_anchor=(0., 1.02, 1., .102), loc=3,
           ncol=2, mode="expand", borderaxespad=0.)

plt.subplot(223)
plt.plot([1,2,3], label="test1")
plt.plot([3,2,1], label="test2")
# Place a legend to the right of this smaller subplot.
plt.legend(bbox_to_anchor=(1.05, 1), loc=2, borderaxespad=0.)

plt.show()

You are going to need to call the SmsManager class. You are probably going to need to use the STATUS_ON_ICC_READ constant and maybe put what you get there into your apps local db so that you can keep track of what you have already read vs the new stuff for your app to parse through. BUT bear in mind that you have to declare the use of the class in your manifest, so users will see that you have access to their SMS called out in the permissions dialogue they get when they install. Seeing SMS access is unusual and could put some users off. Good luck.

Here is the link that goes into depth on the Sms Manager

The correct answer in the present if you dont use Create React App is the next:

new HtmlWebpackPlugin({
   favicon: "./public/fav-icon.ico"
})

If you use CRA then you can modificate the manifest.json in the public directory

No. This is not possible. Use something like supervisord to get an ssh server if that's needed. Although, I definitely question the need.

private String getCurrentDateInSpecificFormat(Calendar currentCalDate) {
    String dayNumberSuffix = getDayNumberSuffix(currentCalDate.get(Calendar.DAY_OF_MONTH));
    DateFormat dateFormat = new SimpleDateFormat(" d'" + dayNumberSuffix + "' MMMM yyyy");
    return dateFormat.format(currentCalDate.getTime());
}

private String getDayNumberSuffix(int day) {
    if (day >= 11 && day <= 13) {
        return "th";
    }
    switch (day % 10) {
    case 1:
        return "st";
    case 2:
        return "nd";
    case 3:
        return "rd";

As indicated by shadowbq, the DirectoryId and TenantId both equate to the GUID representing the ActiveDirectory Tenant. Depending on context, either term may be used by Microsoft documentation and products, which can be confusing.

Assumptions

• You have access to the Azure Portal

Solution

The tenant ID is tied to ActiveDirectoy in Azure

• Navigate to Dashboard
• Navigate to ActiveDirectory
• Navigate to Manage / Properties
• Copy the "Directory ID"

Yes I used paint, don't judge me.

What if you just wrap your code into function?

So this:

cd ~/documents
mkdir test
echo "useless script" > about.txt

Becomes this:

CommentedOutBlock() {
  cd ~/documents
  mkdir test
  echo "useless script" > about.txt
}

I had the same issue, and when I checked if Java is installed I realised it's not, so installing Java solved the problem for me.

Check for java:

java -version

If Java is installed in the system, the command will return the java version otherwise it will show a message like this.

The program 'java' can be found in the following packages:
 * default-jre
 * gcj-5-jre-headless
 * openjdk-8-jre-headless
 * gcj-4.8-jre-headless
 * gcj-4.9-jre-headless
 * openjdk-9-jre-headless

To install java use the following command.

sudo apt-get install default-jre

Try this:

function PluginUrl() {

        //Try to use WP API if possible, introduced in WP 2.6
        if (function_exists('plugins_url')) return trailingslashit(plugins_url(basename(dirname(__FILE__))));

        //Try to find manually... can't work if wp-content was renamed or is redirected
        $path = dirname(__FILE__);
        $path = str_replace("\\","/",$path);
        $path = trailingslashit(get_bloginfo('wpurl')) . trailingslashit(substr($path,strpos($path,"wp-content/")));
        return $path;
    }

echo PluginUrl(); will return the current plugin url.

It's not creating a file because you never actually created the file. You made an object for it. Creating an instance doesn't create the file.

File newFile = new File("directory", "fileName.txt");

You can do this to make a file:

newFile.createNewFile();

You can do this to make a folder:

newFile.mkdir();

BaileyP's answer is already pretty good, but I would use this condition instead:

if(function_exists('get_magic_quotes_gpc') && get_magic_quotes_gpc() === 1){
  $_POST = array_map( 'stripslashes', $_POST );
  $_GET = array_map( 'stripslashes', $_GET );
  $_COOKIE = array_map( 'stripslashes', $_COOKIE );
}

It is more defensive.

$(function() {

$('#clickMe').click(function(event) {
    var mytext = $('#myText').val();

    $('<div id="dialog">'+mytext+'</div>').appendTo('body');        
    event.preventDefault();

        $("#dialog").dialog({                   
            width: 600,
            modal: true,
            close: function(event, ui) {
                $("#dialog").hide();
                }
            });
    }); //close click
});

Better to use .hide() instead of .remove(). With .remove() it returns undefined if you have pressed the link once, then close the modal and if you press the modal link again, it returns undefined with .remove.

With .hide() it doesnt and it works like a breeze. Ty for the snippet in the first hand!

  <input attr1='a' attr2='b' attr3='c'>foo</input>

getAttribute(attr1) you get 'a'

getAttribute(attr2) you get 'b'

getAttribute(attr3) you get 'c'

getText() with no parameter you can only get 'foo'

The reference to the string is passed by value. There's a big difference between passing a reference by value and passing an object by reference. It's unfortunate that the word "reference" is used in both cases.

If you do pass the string reference by reference, it will work as you expect:

using System;

class Test
{
    public static void Main()
    {
        string test = "before passing";
        Console.WriteLine(test);
        TestI(ref test);
        Console.WriteLine(test);
    }

    public static void TestI(ref string test)
    {
        test = "after passing";
    }
}

Now you need to distinguish between making changes to the object which a reference refers to, and making a change to a variable (such as a parameter) to let it refer to a different object. We can't make changes to a string because strings are immutable, but we can demonstrate it with a StringBuilder instead:

using System;
using System.Text;

class Test
{
    public static void Main()
    {
        StringBuilder test = new StringBuilder();
        Console.WriteLine(test);
        TestI(test);
        Console.WriteLine(test);
    }

    public static void TestI(StringBuilder test)
    {
        // Note that we're not changing the value
        // of the "test" parameter - we're changing
        // the data in the object it's referring to
        test.Append("changing");
    }
}

See my article on parameter passing for more details.

You should probably set all of the cookie properties not just the value of it. setPath(), setDomain() ... etc

Just a tip.. Temporary tables in Oracle are different to SQL Server. You create it ONCE and only ONCE, not every session. The rows you insert into it are visible only to your session, and are automatically deleted (i.e., TRUNCATE, not DROP) when you end you session ( or end of the transaction, depending on which "ON COMMIT" clause you use).

I think it is worth considering that you can get the requested info with just a single API call to the standard library...

new Date().toLocaleString( 'sv', { timeZoneName: 'short' } );

// produces "2019-10-30 15:33:47 GMT-4"

You would have to do text swapping if you want to add the 'T' delimiter, remove the 'GMT-', or append the ':00' to the end.

But then you can easily play with the other options if you want to eg. use 12h time or omit the seconds etc.

Note that I'm using Sweden as locale because it is one of the countries that uses ISO 8601 format. I think most of the ISO countries use this 'GMT-4' format for the timezone offset other then Canada which uses the time zone abbreviation eg. "EDT" for eastern-daylight-time.

You can get the same thing from the newer standard i18n function "Intl.DateTimeFormat()" but you have to tell it to include the time via the options or it will just give date.

Make an equals check on the keySet() of both HashMaps.

NOTE:

If your Map contains String keys then it is no problem, but if your Map contains objA type keys then you need to make sure that your class objA implements equals().

As an alternative to using UsedRange or providing an explicit range address, the AutoFilter.Range property can also specify the affected range.

ActiveSheet.AutoFilter.Range.Offset(1,0).Rows.SpecialCells(xlCellTypeVisible).Delete(xlShiftUp)

As used here, Offset causes the first row after the AutoFilter range to also be deleted. In order to avoid that, I would try using .Resize() after .Offset().

Its true the official documentation (Apache log4net™ Manual - Introduction) states there are the following levels...

• ALL
• DEBUG
• INFO
• WARN
• ERROR
• FATAL
• OFF

... but oddly when I view assembly log4net.dll, v1.2.15.0 sealed class log4net.Core.Level I see the following levels defined...

public static readonly Level Alert;
public static readonly Level All;
public static readonly Level Critical;
public static readonly Level Debug;
public static readonly Level Emergency;
public static readonly Level Error;
public static readonly Level Fatal;
public static readonly Level Fine;
public static readonly Level Finer;
public static readonly Level Finest;
public static readonly Level Info;
public static readonly Level Log4Net_Debug;
public static readonly Level Notice;
public static readonly Level Off;
public static readonly Level Severe;
public static readonly Level Trace;
public static readonly Level Verbose;
public static readonly Level Warn;

I have been using TRACE in conjunction with PostSharp OnBoundaryEntry and OnBoundaryExit for a long time. I wonder why these other levels are not in the documentation. Furthermore, what is the true priority of all these levels?

Simple step: Go to the task manager and kill the java process

The webpack2 documentation explains this in a much cleaner way: https://webpack.js.org/guides/public-path/#use-cases

webpack has a highly useful configuration that let you specify the base path for all the assets on your application. It's called publicPath.

Basic Idea

Given possible x values, xs, (think of them as the tick-marks on the x-axis of a plot) and possible y values, ys, meshgrid generates the corresponding set of (x, y) grid points---analogous to set((x, y) for x in xs for y in yx). For example, if xs=[1,2,3] and ys=[4,5,6], we'd get the set of coordinates {(1,4), (2,4), (3,4), (1,5), (2,5), (3,5), (1,6), (2,6), (3,6)}.

Form of the Return Value

However, the representation that meshgrid returns is different from the above expression in two ways:

First, meshgrid lays out the grid points in a 2d array: rows correspond to different y-values, columns correspond to different x-values---as in list(list((x, y) for x in xs) for y in ys), which would give the following array:

   [[(1,4), (2,4), (3,4)],
    [(1,5), (2,5), (3,5)],
    [(1,6), (2,6), (3,6)]]

Second, meshgrid returns the x and y coordinates separately (i.e. in two different numpy 2d arrays):

   xcoords, ycoords = (
       array([[1, 2, 3],
              [1, 2, 3],
              [1, 2, 3]]),
       array([[4, 4, 4],
              [5, 5, 5],
              [6, 6, 6]]))
   # same thing using np.meshgrid:
   xcoords, ycoords = np.meshgrid([1,2,3], [4,5,6])
   # same thing without meshgrid:
   xcoords = np.array([xs] * len(ys)
   ycoords = np.array([ys] * len(xs)).T

Note, np.meshgrid can also generate grids for higher dimensions. Given xs, ys, and zs, you'd get back xcoords, ycoords, zcoords as 3d arrays. meshgrid also supports reverse ordering of the dimensions as well as sparse representation of the result.

Applications

Why would we want this form of output?

Apply a function at every point on a grid: One motivation is that binary operators like (+, -, *, /, **) are overloaded for numpy arrays as elementwise operations. This means that if I have a function def f(x, y): return (x - y) ** 2 that works on two scalars, I can also apply it on two numpy arrays to get an array of elementwise results: e.g. f(xcoords, ycoords) or f(*np.meshgrid(xs, ys)) gives the following on the above example:

array([[ 9,  4,  1],
       [16,  9,  4],
       [25, 16,  9]])

Higher dimensional outer product: I'm not sure how efficient this is, but you can get high-dimensional outer products this way: np.prod(np.meshgrid([1,2,3], [1,2], [1,2,3,4]), axis=0).

Contour plots in matplotlib: I came across meshgrid when investigating drawing contour plots with matplotlib for plotting decision boundaries. For this, you generate a grid with meshgrid, evaluate the function at each grid point (e.g. as shown above), and then pass the xcoords, ycoords, and computed f-values (i.e. zcoords) into the contourf function.

Did you include a reference to System.Web.Extensions? If you click on your first link it says which assembly it's in.

instead of files use pipes and if u wana use C and not C++ u can use popen like this

#include<stdlib.h>
#include<stdio.h>

FILE *fp= popen("date +F","r");

and use *fp as a normal file pointer with fgets and all

if u wana use c++ strings, fork a child, invoke the command and then pipe it to the parent.

   #include <stdlib.h>
   #include <iostream>
   #include <string>
   using namespace std;

   string currentday;
   int dependPipe[2];

   pipe(dependPipe);// make the pipe

   if(fork()){//parent
           dup2(dependPipe[0],0);//convert parent's std input to pipe's output
           close(dependPipe[1]);
           getline(cin,currentday);

    } else {//child
        dup2(dependPipe[1],1);//convert child's std output to pipe's input
        close(dependPipe[0]);

        system("date +%F");
    }

// make a similar 1 for date +T but really i recommend u stick with stuff in time.h GL

A VIP swap is an internal change to Azure's routers/load balancers, not an external DNS change. They're just routing traffic to go from one internal [set of] server[s] to another instead. Therefore the DNS info for mysite.cloudapp.net doesn't change at all. Therefore the change for people accessing via the IP bound to mysite.cloudapp.net (and CNAME'd by you) will see the change as soon as the VIP swap is complete.

set -e stops the execution of a script if a command or pipeline has an error - which is the opposite of the default shell behaviour, which is to ignore errors in scripts. Type help set in a terminal to see the documentation for this built-in command.

There is a timeout on broken connections (i.e. due to network errors), which relies on the OS' TCP keepalive feature. By default on Linux, broken TCP connections are closed after ~2 hours (see sysctl net.ipv4.tcp_keepalive_time).

There is also a timeout on abandoned transactions, idle_in_transaction_session_timeout and on locks, lock_timeout. It is recommended to set these in postgresql.conf.

But there is no timeout for a properly established client connection. If a client wants to keep the connection open, then it should be able to do so indefinitely. If a client is leaking connections (like opening more and more connections and never closing), then fix the client. Do not try to abort properly established idle connections on the server side.

For Perl one-liners with implicit loops (using -n or -p command line options), use last or last LINE to break out of the loop that iterates over input records. For example, these simple examples all print the first 2 lines of the input:

echo 1 2 3 4 | xargs -n1 | perl -ne 'last if $. == 3; print;'
echo 1 2 3 4 | xargs -n1 | perl -ne 'last LINE if $. == 3; print;'
echo 1 2 3 4 | xargs -n1 | perl -pe 'last if $. == 3;'
echo 1 2 3 4 | xargs -n1 | perl -pe 'last LINE if $. == 3;'

All print:

1
2

The perl one-liners use these command line flags:
-e : tells Perl to look for code in-line, instead of in a file.
-n : loop over the input one line at a time, assigning it to $_ by default.
-p : same as -n, also add print after each loop iteration over the input.

I've experienced same problem with same lib, found a solution here on SO:

Search MSDN for "How to: Set Environment Variables for Projects". (It's Project>Properties>Configuration Properties>Debugging "Environment" and "Merge Environment" properties for those who are in a rush.)

The syntax is NAME=VALUE and macros can be used (for example, $(OutDir)).

For example, to prepend C:\Windows\Temp to the PATH:

PATH=C:\WINDOWS\Temp;%PATH%

Similarly, to append $(TargetDir)\DLLS to the PATH:

PATH=%PATH%;$(TargetDir)\DLLS

(answered by Multicollinearity here: How do I set a path in visual studio?

Drawable d = getResources().getDrawable(android.R.drawable.ic_dialog_email);
ImageView image = (ImageView)findViewById(R.id.image);
image.setImageDrawable(d);

Try the following (note that there should not be a space between the VAR, =, and GREG).

SET VAR=GREG
ECHO %VAR%
PAUSE

wrap you shared code into another function:

<script>
  function myFun () {
      //do something
  }

  $(document).ready(function(){
    //Load City by State
    $(document).on('change', '#billing_state_id', function() {
       myFun ();
    });   
    $(document).on('click', '#click_me', function() {
       //do something
       myFun();
    });   
  });
</script>

Your "listen" directives are wrong. See this page: http://nginx.org/en/docs/http/server_names.html.

They should be

server {
    listen      80;
    server_name www.domain1.com;
    root /var/www/domain1;
}

server {
    listen       80;
    server_name www.domain2.com;
    root /var/www/domain2;
}

Note, I have only included the relevant lines. Everything else looked okay but I just deleted it for clarity. To test it you might want to try serving a text file from each server first before actually serving php. That's why I left the 'root' directive in there.

You need to declare @font-face like this in your stylesheet

@font-face {
  font-family: 'Awesome-Font';
  font-style: normal;
  font-weight: 400;
  src: local('Awesome-Font'), local('Awesome-Font-Regular'), url(path/Awesome-Font.woff) format('woff');
}

Now if you want to apply this font to a paragraph simply use it like this..

p {
font-family: 'Awesome-Font', Arial;
}

Starting Mongo 4.2, db.collection.update() can accept an aggregation pipeline, finally allowing the update/creation of a field based on another field:

// { firstName: "Hello", lastName: "World" }
db.collection.update(
  {},
  [{ $set: { name: { $concat: [ "$firstName", " ", "$lastName" ] } } }],
  { multi: true }
)
// { "firstName" : "Hello", "lastName" : "World", "name" : "Hello World" }

• The first part {} is the match query, filtering which documents to update (in our case all documents).

• The second part [{ $set: { name: { ... } }] is the update aggregation pipeline (note the squared brackets signifying the use of an aggregation pipeline). $set is a new aggregation operator and an alias of $addFields.

• Don't forget { multi: true }, otherwise only the first matching document will be updated.

Yes, Eclipse can be a pain, as almost any IDE can. Please remain factual, however.

Switching to a new workspace should help you. Eclipse has almost no settings that are stored outside your workspace.

The spirit of Web font is to use cache as much as possible, therefore you should use CDN version between <head></head> instead of hosting yourself:

<link href="//netdna.bootstrapcdn.com/font-awesome/3.2.1/css/font-awesome.css" rel="stylesheet">

Also, make sure you loaded your CSS AFTER the above line, or your custom font CSS won't work.

It means that zero or more String objects (or a single array of them) may be passed as the argument(s) for that method.

See the "Arbitrary Number of Arguments" section here: http://java.sun.com/docs/books/tutorial/java/javaOO/arguments.html#varargs

In your example, you could call it as any of the following:

myMethod(); // Likely useless, but possible
myMethod("one", "two", "three");
myMethod("solo");
myMethod(new String[]{"a", "b", "c"});

Important Note: The argument(s) passed in this way is always an array - even if there's just one. Make sure you treat it that way in the method body.

Important Note 2: The argument that gets the ... must be the last in the method signature. So, myMethod(int i, String... strings) is okay, but myMethod(String... strings, int i) is not okay.

Thanks to Vash for the clarifications in his comment.

In your comparator factory class, do something like this:

 private static final Comparator<String> MYSTRING_COMPARATOR = new Comparator<String>() {
    @Override
    public int compare(String s1, String s2) {
      return s1.compareToIgnoreCase(s2);
    }
  };

  public static Comparator<String> getMyStringComparator() {
    return MYSTRING_COMPARATOR;

This uses the compare to method which is case insensitive (why write your own). This way you can use Collections sort like this:

List<String> myArray = new ArrayList<String>();
//fill your array here    
Collections.sort(MyArray, MyComparators. getMyStringComparator());

Also, you can use an IDE like CLion (JetBrains) or a text editor like Atom, with the gpp-compiler plugin, works like a charm (F5 to compile & execute).

I was looking for a really simple way to get PHP to send a socket.io message to clients.

This doesn't require any additional PHP libraries - it just uses sockets.

Instead of trying to connect to the websocket interface like so many other solutions, just connect to the node.js server and use .on('data') to receive the message.

Then, socket.io can forward it along to clients.

Detect a connection from your PHP server in Node.js like this:

//You might have something like this - just included to show object setup
var app = express();
var server = http.createServer(app);
var io = require('socket.io').listen(server);

server.on("connection", function(s) {
    //If connection is from our server (localhost)
    if(s.remoteAddress == "::ffff:127.0.0.1") {
        s.on('data', function(buf) {
            var js = JSON.parse(buf);
            io.emit(js.msg,js.data); //Send the msg to socket.io clients
        });
    }
});

Here's the incredibly simple php code - I wrapped it in a function - you may come up with something better.

Note that 8080 is the port to my Node.js server - you may want to change.

function sio_message($message, $data) {
    $socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
    $result = socket_connect($socket, '127.0.0.1', 8080);
    if(!$result) {
        die('cannot connect '.socket_strerror(socket_last_error()).PHP_EOL);
    }
    $bytes = socket_write($socket, json_encode(Array("msg" => $message, "data" => $data)));
    socket_close($socket);
}

You can use it like this:

sio_message("chat message","Hello from PHP!");

You can also send arrays which are converted to json and passed along to clients.

sio_message("DataUpdate",Array("Data1" => "something", "Data2" => "something else"));

This is a useful way to "trust" that your clients are getting legitimate messages from the server.

You can also have PHP pass along database updates without having hundreds of clients query the database.

I wish I'd found this sooner - hope this helps!

Also you can do like this:

<select class="form-control postType" ng-model="selectedProd">
    <option ng-repeat="product in productList" value="{{product}}">{{product.name}}</option>
</select>

where "selectedProd" will be selected product.

tl;dr

LocalDate.now()       // Capture the date-only value current in the JVM’s current default time zone.
         .getYear()   // Extract the year number from that date.

2018

java.time

Both the java.util.Date and java.util.Calendar classes are legacy, now supplanted by the java.time framework built into Java 8 and later.

A time zone is crucial in determining a date. For any given moment, the date varies around the globe by zone. For example, a few minutes after midnight in Paris France is a new day while still “yesterday” in Montréal Québec.

If no time zone is specified, the JVM implicitly applies its current default time zone. That default may change at any moment, so your results may vary. Better to specify your desired/expected time zone explicitly as an argument.

Specify a proper time zone name in the format of continent/region, such as America/Montreal, Africa/Casablanca, or Pacific/Auckland. Never use the 3-4 letter abbreviation such as EST or IST as they are not true time zones, not standardized, and not even unique(!).

ZoneId z = ZoneId.of( "Africa/Tunis" ) ;  

If you want only the date without time-of-day, use LocalDate. This class lacks time zone info but you can specify a time zone to determine the current date.

ZoneId zoneId = ZoneId.of( "America/Montreal" );
LocalDate localDate = LocalDate.now( zoneId );

You can get the various pieces of information with getYear, getMonth, and getDayOfMonth. You will actually get the year number with java.time!

int year = localDate.getYear();

2016

If you want a date-time instead of just a date, use ZonedDateTime class.

ZonedDateTime zdt = ZonedDateTime.now( zoneId ) ;

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old date-time classes such as java.util.Date, .Calendar, & java.text.SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations.

Much of the java.time functionality is back-ported to Java 6 & Java 7 in ThreeTen-Backport and further adapted to Android in ThreeTenABP (see How to use…).

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

You could just outright select the elements of interest.

$('a[href*="?"]').each(function() {
    alert('Contains question mark');
});

Note that you were using the attribute-ends-with selector, the above code uses the attribute-contains selector, which is what it sounds like you're actually aiming for.

I have aggregated with Qty wise data and store to dataframe

almo_grp_data = pd.DataFrame({'Qty_cnt' :
almo_slt_models_data.groupby( ['orderDate','Item','State Abv']
          )['Qty'].sum()}).reset_index()

In my implementation, the cell I was referencing could have been several options. I used the following format where 'ws' is the current worksheet being edited

For each ws in Activeworkbook.Worksheets
    For i…
       For j...
...
ws.Cells(i, j).Value = "=HYPERLINK(""#'" & SHEET-REF-VAR & "'!" & CELL-REF-VAR & """,""" & SHEET-REF-VAR & """)"

You can use timespan

TimeSpan timeSpan = new TimeSpan(2, 14, 18);
Console.WriteLine(timeSpan.ToString());     // Displays "02:14:18".

[Edit]
Considering the other answers and the edit to the question, I would still use TimeSpan. No point in creating a new structure where an existing one from the framework suffice.
On these lines you would end up duplicating many native data types.

This answer is for TextInputEditText :

In the layout XML file set your input method options to your required type. for example done.

<com.google.android.material.textfield.TextInputLayout
        android:id="@+id/textInputLayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <com.google.android.material.textfield.TextInputEditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:imeOptions="actionGo"/>

</com.google.android.material.textfield.TextInputLayout>

Similarly, you can also set imeOptions to actionSubmit, actionSearch, etc

In the java add the editor action listener.

TextInputLayout textInputLayout = findViewById(R.id.textInputLayout);

textInputLayout.getEditText().setOnEditorActionListener(new 

    TextView.OnEditorActionListener() {
        @Override
        public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
            if (actionId == EditorInfo.IME_ACTION_GO) {
                performYourAction();
                return true;
            }
            return false;
        }
    });

If you're using kotlin :

textInputLayout.editText.setOnEditorActionListener { _, actionId, _ ->
    if (actionId == EditorInfo.IME_ACTION_GO) {
        performYourAction()
    }
    true
}

I fixed this issue with :

varchar(200) 

replaced with

varchar(191)

all the unique or primary varchar keys which have more than 200 replace them with 191 or set them as text.

You could use Unity Builds.

It will create your repository in the .git folder in the current directory.

Just use myView.setVisibility(View.GONE); to remove it completely. But if you want to reserve the occupied space inside its parent use myView.setVisibility(View.INVISIBLE);

I've simply combined the best bits from the other answers:

$(document).keydown(function(e){
    switch(e.which) {
        case $.ui.keyCode.LEFT:
        // your code here
        break;

        case $.ui.keyCode.UP:
        // your code here
        break;

        case $.ui.keyCode.RIGHT:
        // your code here
        break;

        case $.ui.keyCode.DOWN:
        // your code here
        break;

        default: return; // allow other keys to be handled
    }

    // prevent default action (eg. page moving up/down)
    // but consider accessibility (eg. user may want to use keys to choose a radio button)
    e.preventDefault();
});

Twisted has SSH support : http://www.devshed.com/c/a/Python/SSH-with-Twisted/

The twisted.conch package adds SSH support to Twisted. This chapter shows how you can use the modules in twisted.conch to build SSH servers and clients.

Setting Up a Custom SSH Server

The command line is an incredibly efficient interface for certain tasks. System administrators love the ability to manage applications by typing commands without having to click through a graphical user interface. An SSH shell is even better, as it’s accessible from anywhere on the Internet.

You can use twisted.conch to create an SSH server that provides access to a custom shell with commands you define. This shell will even support some extra features like command history, so that you can scroll through the commands you’ve already typed.

How Do I Do That? Write a subclass of twisted.conch.recvline.HistoricRecvLine that implements your shell protocol. HistoricRecvLine is similar to twisted.protocols.basic.LineReceiver , but with higher-level features for controlling the terminal.

Write a subclass of twisted.conch.recvline.HistoricRecvLine that implements your shell protocol. HistoricRecvLine is similar to twisted.protocols.basic.LineReceiver, but with higher-level features for controlling the terminal.

To make your shell available through SSH, you need to implement a few different classes that twisted.conch needs to build an SSH server. First, you need the twisted.cred authentication classes: a portal, credentials checkers, and a realm that returns avatars. Use twisted.conch.avatar.ConchUser as the base class for your avatar. Your avatar class should also implement twisted.conch.interfaces.ISession , which includes an openShell method in which you create a Protocol to manage the user’s interactive session. Finally, create a twisted.conch.ssh.factory.SSHFactory object and set its portal attribute to an instance of your portal.

Example 10-1 demonstrates a custom SSH server that authenticates users by their username and password. It gives each user a shell that provides several commands.

Example 10-1. sshserver.py

I've used this library before which does a pretty good job of what you're after. Specifically:-

qs.contains(name)
    Returns true if the querystring has a parameter name, else false.

    if (qs2.contains("name1")){ alert(qs2.get("name1"));}

perl one-liner alert

just for fun... print only one line after match

perl -lne '$next = ($.+1) if /match/; $. == $next && print' data.txt

even more fun... print the next ten lines after match

perl -lne 'push @nexts, (($.+1)..($.+10)) if /match/; $. ~~ @nexts && print' data.txt

kinda cheating though since there's actually two commands

Make sure you that your target in System.IO.Delete(string file) is a file which is existed. Maybe there is a mistake in your code ;Like you don't pass the correct file name to the method , or your target is a folder. In these cases you'll see the : "access to the path is denied error".

I used this method and managed to get the desired output. my script

As quoted by the FAQ, you should call the destructor explicitly when using placement new.

This is about the only time you ever explicitly call a destructor.

I agree though that this is seldom needed.

Create an interface IFooable, then make your A and B classes to implement a common method, which in turn calls the corresponding method you want:

interface IFooable
{
    public void Foo();
}

class A : IFooable
{
    //other methods ...

    public void Foo()
    {
        this.Hop();
    }
}

class B : IFooable
{
    //other methods ...

    public void Foo()
    {
        this.Skip();
    }
}

class ProcessingClass
{
    public void Foo(object o)
    {
        if (o == null)
            throw new NullRefferenceException("Null reference", "o");

        IFooable f = o as IFooable;
        if (f != null)
        {
            f.Foo();
        }
        else
        {
            throw new ArgumentException("Unexpected type: " + o.GetType());
        }
    }
}

Note, that it's better to use as instead first checking with is and then casting, as that way you make 2 casts, so it's more expensive.

I inspired by code Sean Patrick Floyd and little rewrite it for maximum performance i get.

public static String stripNonDigitsV2( CharSequence input ) {
    if (input == null)
        return null;
    if ( input.length() == 0 )
        return "";

    char[] result = new char[input.length()];
    int cursor = 0;
    CharBuffer buffer = CharBuffer.wrap( input );

    while ( buffer.hasRemaining() ) {
        char chr = buffer.get();
        if ( chr > 47 && chr < 58 )
            result[cursor++] = chr;
    }

    return new String( result, 0, cursor );
}

i do Performance test to very long String with minimal numbers and result is:

• Original code is 25,5% slower
• Guava approach is 2.5-3 times slower
• Regular expression with D+ is 3-3.5 times slower
• Regular expression with only D is 25+ times slower

Btw it depends on how long that string is. With string that contains only 6 number is guava 50% slower and regexp 1 times slower

Create key value pairs on the phpsh commandline like this:

php> $keyvalues = array();
php> $keyvalues['foo'] = "bar";
php> $keyvalues['pyramid'] = "power";
php> print_r($keyvalues);
Array
(
    [foo] => bar
    [pyramid] => power
)

Get the count of key value pairs:

php> echo count($offerarray);
2

Get the keys as an array:

php> echo implode(array_keys($offerarray));
foopyramid

An adventage of use ExpectedException Rule (version 4.7) is that you can test exception message and not only the expected exception.

And using Matchers, you can test the part of message you are interested:

exception.expectMessage(containsString("income: -1000.0"));

As a matter of fact, HTML character entites also work : http://www.w3.org/TR/html4/sgml/entities.html.

It lets you insert special characters like bullets '•' (&bull;), '™' (&trade;), ... the HTML way.

Note that you can also (and probably should) type special characters directly in the form fields if you can enter international characters.

=> one consideration here is whether or not you care about third-party sites that collect data on your app from Google Play : some might simply take it as HTML content, others might insert it in a native application that just understand plain Unicode...

Yes, play with figuresize and dpi like so (before you call your subplot):

fig=plt.figure(figsize=(12,8), dpi= 100, facecolor='w', edgecolor='k')

As @tacaswell and @Hagne pointed out, you can also change the defaults if it's not a one-off:

plt.rcParams['figure.figsize'] = [12, 8]
plt.rcParams['figure.dpi'] = 100 # 200 e.g. is really fine, but slower

You have a version conflict, please verify whether compiled version and JVM of Tomcat version are same. you can do it by examining tomcat startup .bat , looking for JAVA_HOME

Granted you have administrative Windows privileges on the server, another option would be to start SQL Server in Single User Mode, using the Startup parameter "-m". Doing this, you can login using SQLCMD, create a new user and give it sysadmin privileges. Finally, you have to disable Single User Mode, login to SSMS using your new user, and go to Segurity/Logins and change "sa" user password.

You can check this post: http://v-consult.be/2011/05/26/recover-sa-password-microsoft-sql-server-2008-r2/

Here (http://www.dotnetperls.com/picturebox) there 3 ways to do this:

• Like you are doing.

• Using ImageLocation property of the PictureBox like:

  private void Form1_Load(object sender, EventArgs e)
  {
      PictureBox pb1 = new PictureBox();            
      pb1.ImageLocation = "../SamuderaJayaMotor.png";
      pb1.SizeMode = PictureBoxSizeMode.AutoSize;
  }
  

• Using an image from the web like:

  private void Form1_Load(object sender, EventArgs e)
  {
      PictureBox pb1 = new PictureBox();            
      pb1.ImageLocation = "http://www.dotnetperls.com/favicon.ico";
      pb1.SizeMode = PictureBoxSizeMode.AutoSize;
  }
  

And please, be sure that "../SamuderaJayaMotor.png" is the correct path of the image that you are using.

There seem to be many answers suggesting:

process.stdout.write

Error logs should be emitted on:

process.stderr

Instead use:

console.error

For anyone who is wonder why process.stdout.write('\033[0G'); wasn't doing anything it's because stdout is buffered and you need to wait for drain event (more info).

If write returns false it will fire a drain event.

I've ran into this problem as well, and this is how I solved my problem

webapi code:

public void Post([FromBody] dynamic data)
{
    string value = data.value;
    /* do stuff */
}

client code:

$.post( "webapi/address", { value: "some value" } );

Create a new sub with the following code and assign it to your button. Change the "DeleteProcess" to the name of your code to do the deletion. This will pop up a box with OK or Cancel and will call your delete sub if you hit ok and not if you hit cancel.

Sub AreYouSure()

Dim Sure As Integer

Sure = MsgBox("Are you sure?", vbOKCancel)
If Sure = 1 Then Call DeleteProcess

End Sub

For me the reason was that one device, a Xiaomi Mi 9 just was not working anymore and not displaying ads, so I pulled out my tablet and I saw no errors and it was displaying ads in the release.

Shameless plug: I'm working on Bokeh: a simple, scalable and blazing-fast task queue built on ZeroMQ. It supports pluggable data stores for persisting tasks, currently in-memory, Redis and Riak are supported. Check it out.

You seem to just have begun using mysql.

Simple answer: for now use

mysql -u root -p password

Password is usually root by default. You may use other usernames if you have created other user using create user in mysql. For details use "help, help manage accounts, help create users" etc. If you dont want your password to be shown in open just press return key after "-p" and you will be prompted for password next. Hope this resolves the issue.

Just to kick a long-dead horse, because I've had to implement an optional argument in the middle of two or more required arguments. Use the arguments array and use the last one as the required non-optional argument.

my_function() {
  var options = arguments[argument.length - 1];
  var content = arguments.length > 1 ? arguments[0] : null;
}

That's correct, and documented:

http://java.sun.com/javase/6/docs/api/java/util/Collections.html#synchronizedList(java.util.List)

However, to clear the list, just call List.clear().

This might come a little late...

I wrote this KalmanLocationManager for Android, which wraps the two most common location providers, Network and GPS, kalman-filters the data, and delivers updates to a LocationListener (like the two 'real' providers).

I use it mostly to "interpolate" between readings - to receive updates (position predictions) every 100 millis for instance (instead of the maximum gps rate of one second), which gives me a better frame rate when animating my position.

Actually, it uses three kalman filters, on for each dimension: latitude, longitude and altitude. They're independent, anyway.

This makes the matrix math much easier: instead of using one 6x6 state transition matrix, I use 3 different 2x2 matrices. Actually in the code, I don't use matrices at all. Solved all equations and all values are primitives (double).

The source code is working, and there's a demo activity. Sorry for the lack of javadoc in some places, I'll catch up.

From the documentation I found this

JObject o = new JObject(
   new JProperty("Name", "John Smith"),
   new JProperty("BirthDate", new DateTime(1983, 3, 20))
);

JsonSerializer serializer = new JsonSerializer();
Person p = (Person)serializer.Deserialize(new JTokenReader(o), typeof(Person));

Console.WriteLine(p.Name);

The class definition for Person should be compatible to the following:

class Person {
    public string Name { get; internal set; }
    public DateTime BirthDate { get; internal set; }
}

Edit

If you are using a recent version of JSON.net and don't need custom serialization, please see TienDo's answer above (or below if you upvote me :P ), which is more concise.

Your /home/gnu/bin/c++ seem to require additional flag to link things properly and CMake doesn't know about that.

To use /usr/bin/c++ as your compiler run cmake with -DCMAKE_CXX_COMPILER=/usr/bin/c++.

Also, CMAKE_PREFIX_PATH variable sets destination dir where your project' files should be installed. It has nothing to do with CMake installation prefix and CMake itself already know this.

You could use HTML entities:

• ' for '
• " for "
• ...

For more, you can take a look at Character entity references in HTML.

1. You are putting there a two-digits year. The first century. And the Gregorian calendar started in the 16th century. I think you should add 2000 to the year.

2. Month in the function new GregorianCalendar(year, month, days) is 0-based. Subtract 1 from the month there.

3. Change the body of the second function as follows:

       String dateFormatted = null;
       SimpleDateFormat fmt = new SimpleDateFormat("dd-MMM-yyyy");
       try {
           dateFormatted = fmt.format(date);
       }
       catch ( IllegalArgumentException e){
           System.out.println(e.getMessage());
       }
       return dateFormatted;
   

After debugging, you'll see that simply GregorianCalendar can't be an argument of the fmt.format();.

Really, nobody needs GregorianCalendar as output, even you are told to return "a string".

Change the header of your format function to

public static String format(final Date date) 

and make the appropriate changes. fmt.format() will take the Date object gladly.

4. Always after an unexpected exception arises, catch it yourself, don't allow the Java machine to do it. This way, you'll understand the problem.

MAC users - this issue was winding me up, as its not possible to open two different Visual Studio instances at the same time. Ive found a solution that works fine, though its a little unorthodox : get the latest beta testing version, which will install alongside your normal VS install in a separate sandbox (it does this automatically). You can then run both versions side by side, which is enough for what I needed - to be able to examine one project for structure, code etc., while doing the actual coding I need to do in the 'current' VS install instance.

A non-query way would be to use the Sql Server Management Studio.

Locate the table, right click and choose "View dependencies".

EDIT

But, as the commenters said, it is not very reliable.

if you put your full code here so i can help you. if your setting the listener in XML and calling the set background color on View so it will change the background color of the view means it ur Botton so put ur listener in ur activity and then change the color of your view

See here: Cross Browser favicon

Thats the way to go:

<link rel="icon" type="image/png" href="http://www.example.com/image.png"><!-- Major Browsers -->
<!--[if IE]><link rel="SHORTCUT ICON" href="http://www.example.com/alternateimage.ico"/><![endif]--><!-- Internet Explorer-->

I was getting this error though there were no (obvious) brackets in my URL, and in my situation the --globoff command will not solve the issue.

For example (doing this on on mac in iTerm2):

for endpoint in $(grep some_string output.txt); do curl "http://1.2.3.4/api/v1/${endpoint}" ; done

I have grep aliased to "grep --color=always". As a result, the above command will result in this error, with some_string highlighted in whatever colour you have grep set to:

curl: (3) bad range in URL position 31:
http://1.2.3.4/api/v1/lalalasome_stringlalala

The terminal was transparently translating the [colour\codes]some_string[colour\codes] into the expected no-special-characters URL when viewed in terminal, but behind the scenes the colour codes were being sent in the URL passed to curl, resulting in brackets in your URL.

Solution is to not use match highlighting.

It depends on which level you selected in your log4j configuration file.

<Loggers>
        <Root level="info">
        ...

If your level is "info" (by default), logger.debug(...) will not be printed in your console. However, if your level is "debug", it will.

Depending on the criticality level of your code, you should use the most accurate level among the following ones :

ALL < TRACE < DEBUG < INFO < WARN < ERROR < FATAL < OFF

config.autoload_paths does not work for me. I solve it in other way

Ruby on rails 3 do not automatic reload (autoload) code from /lib folder. I solve it by putting inside ApplicationController

Dir["lib/**/*.rb"].each do |path|
  require_dependency path
end 

This is how you should do it : ( for google find)

$([
  {"name":"Lenovo Thinkpad 41A4298","website":"google222"},
  {"name":"Lenovo Thinkpad 41A2222","website":"google"}
  ])
    .filter(function (i,n){
        return n.website==='google';
    });

Better solution : ( Salman's)

$.grep( [{"name":"Lenovo Thinkpad 41A4298","website":"google"},{"name":"Lenovo Thinkpad 41A2222","website":"google"}], function( n, i ) {
  return n.website==='google';
});

I'm using jquery with yql for feed. You can retrieve twitter,rss,buzz with yql. I read from http://tutorialzine.com/2010/02/feed-widget-jquery-css-yql/ . It's very useful for me.

They don't do the same thing. The first one works if obj is of type ClassA or of some subclass of ClassA. The second one will only match objects of type ClassA. The second one will be faster since it doesn't have to check the class hierarchy.

For those who want to know the reason, but don't want to read the article referenced in is vs typeof.

Try running the following program. You just have to be sure your window has the focus when you hit Return--to ensure that it does, first click the button a couple of times until you see some output, then without clicking anywhere else hit Return.

import tkinter as tk

root = tk.Tk()
root.geometry("300x200")

def func(event):
    print("You hit return.")
root.bind('<Return>', func)

def onclick():
    print("You clicked the button")

button = tk.Button(root, text="click me", command=onclick)
button.pack()

root.mainloop()

Then you just have tweak things a little when making both the button click and hitting Return call the same function--because the command function needs to be a function that takes no arguments, whereas the bind function needs to be a function that takes one argument(the event object):

import tkinter as tk

root = tk.Tk()
root.geometry("300x200")

def func(event):
    print("You hit return.")

def onclick(event=None):
    print("You clicked the button")

root.bind('<Return>', onclick)

button = tk.Button(root, text="click me", command=onclick)
button.pack()

root.mainloop()

Or, you can just forgo using the button's command argument and instead use bind() to attach the onclick function to the button, which means the function needs to take one argument--just like with Return:

import tkinter as tk

root = tk.Tk()
root.geometry("300x200")

def func(event):
    print("You hit return.")

def onclick(event):
    print("You clicked the button")

root.bind('<Return>', onclick)

button = tk.Button(root, text="click me")
button.bind('<Button-1>', onclick)
button.pack()

root.mainloop()

Here it is in a class setting:

import tkinter as tk

class Application(tk.Frame):
    def __init__(self):
        self.root = tk.Tk()
        self.root.geometry("300x200")

        tk.Frame.__init__(self, self.root)
        self.create_widgets()

    def create_widgets(self):
        self.root.bind('<Return>', self.parse)
        self.grid()

        self.submit = tk.Button(self, text="Submit")
        self.submit.bind('<Button-1>', self.parse)
        self.submit.grid()

    def parse(self, event):
        print("You clicked?")

    def start(self):
        self.root.mainloop()


Application().start()

Modulus division gives you the remainder of a division, rather than the quotient.

For ASP.NET 5.0, I have an extension method as follow:

using System;
using System.ComponentModel;
using System.Security.Claims;

namespace YOUR_PROJECT.Presentation.WebUI.Extensions
{
    public static class ClaimsPrincipalExtensions
    {
        public static TId GetId<TId>(this ClaimsPrincipal principal)
        {
            if (principal == null || principal.Identity == null || 
                !principal.Identity.IsAuthenticated)
            {
                throw new ArgumentNullException(nameof(principal));
            }

            var loggedInUserId = principal.FindFirstValue(ClaimTypes.NameIdentifier);

            if (typeof(TId) == typeof(string) || 
                typeof(TId) == typeof(int) || 
                typeof(TId) == typeof(long) || 
                typeof(TId) == typeof(Guid))
            {
                var converter = TypeDescriptor.GetConverter(typeof(TId));

                return (TId)converter.ConvertFromInvariantString(loggedInUserId);
            }

            throw new InvalidOperationException("The user id type is invalid.");
        }

        public static Guid GetId(this ClaimsPrincipal principal)
        {
            return principal.GetId<Guid>();
        }
    }
}

So you can use it like:

using Microsoft.AspNetCore.Mvc;
using YOUR_PROJECT.Presentation.WebUI.Extensions;

namespace YOUR_PROJECT.Presentation.WebUI.Controllers
{
    public class YourController :Controller
    {
        public IActionResult YourMethod()
        {
            // If it's Guid
            var userId = User.GetId();

            // Or
            // var userId = User.GetId<int>();

            return View();
        }
    }
}

Here's a version that searches both columns.

$("#search").keyup(function () {
    var value = this.value.toLowerCase().trim();

    $("table tr").each(function (index) {
        if (!index) return;
        $(this).find("td").each(function () {
            var id = $(this).text().toLowerCase().trim();
            var not_found = (id.indexOf(value) == -1);
            $(this).closest('tr').toggle(!not_found);
            return not_found;
        });
    });
});

demo: http://jsfiddle.net/rFGWZ/369/

You can make:

$values = array_values($array);
echo $values[0];

Its work perfectly

ALTER TABLE `products` ADD `LastUpdate` varchar(200) NULL;

But if you want more precise in table then you can try AFTER.

ALTER TABLE `products` ADD `LastUpdate` varchar(200) NULL AFTER `column_name`;

It will add LastUpdate column after specified column name (column_name).

Well that's very interesting, Here is quick and working code:

MySQL queries are not case-sensitive by default. Following is a simple query that is looking for 'value'. However it will return 'VALUE', 'value', 'VaLuE', etc…

SELECT * FROM `table` WHERE `column` = 'value'

The good news is that if you need to make a case-sensitive query, it is very easy to do using the BINARY operator, which forces a byte by byte comparison:

SELECT * FROM `table` WHERE BINARY `column` = 'value'

An expression of non-boolean type specified in a context where a condition is expected

I also got this error when I forgot to add ON condition when specifying my join clause.

You can define more details by extending AbstractMongoConfiguration.

@Configuration
@EnableMongoRepositories("demo.mongo.model")
public class SpringMongoConfig extends AbstractMongoConfiguration {
    @Value("${spring.profiles.active}")
    private String profileActive;

    @Value("${spring.application.name}")
    private String proAppName;

    @Value("${spring.data.mongodb.host}")
    private String mongoHost;

    @Value("${spring.data.mongodb.port}")
    private String mongoPort;

    @Value("${spring.data.mongodb.database}")
    private String mongoDB;

    @Override
    public MongoMappingContext mongoMappingContext()
        throws ClassNotFoundException {
        // TODO Auto-generated method stub
        return super.mongoMappingContext();
    }
    @Override
    @Bean
    public Mongo mongo() throws Exception {
        return new MongoClient(mongoHost + ":" + mongoPort);
    }
    @Override
    protected String getDatabaseName() {
        // TODO Auto-generated method stub

The code below will show difference for found values only, i.e., if years = 0, then it will not show years.

$diffs = [

    'months' => 'm',
    'days' => 'd',
    'hours' => 'h',
    'minutes' => 'i',
    'seconds' => 's'
];

$interval = $timeout->diff($timein);
$diffArr = [];
foreach ($diffs as $k => $v) {
    $d = $interval->format('%' . $v);
    if ($d > 0) {
        $diffArr[] = $d . ' ' . $k;
    }
}    
$diffStr = implode(', ', $diffArr);
echo 'Difference: ' . ($diffStr == '' ? '0' : $diffStr) . PHP_EOL;

Simplest way is to Check the Output - Build tab: It would display the location of war file.
It will have something like:

Installing D:\Project\target\Tool.war to C:\Users\myname.m2\repository\com\tool\1.0\Tool-1.0.war

You can't just return an array of objects because there's nothing telling React how to render that. You'll need to return an array of components or elements like:

render: function() {
  return (
    <span>
      // This will go through all the elements in arrayFromJson and
      // render each one as a <SomeComponent /> with data from the object
      {this.state.arrayFromJson.map(function(object) {
        return (
          <SomeComponent key={object.id} data={object} />
        );
      })}
    </span>
  );
}

I am using the following test to see if strings have been urlencoded:

if(urlencode($str) != str_replace(['%','+'], ['%25','%2B'], $str))

If a string has already been urlencoded, the only characters that will changed by double encoding are % (which starts all encoded character strings) and + (which replaces spaces.) Change them back and you should have the original string.

Let me know if this works for you.

The fifth method in Leo Sauers answer fails, if the character is on the beginning of the string. e.g.

var needle ='A',
  haystack = 'AbcAbcAbc';

haystack.split('').map( function(e,i){ if(e === needle) return i;} )
  .filter(Boolean).length;

will give 2 instead of 3, because the filter funtion Boolean gives false for 0.

Other possible filter function:

haystack.split('').map(function (e, i) {
  if (e === needle) return i;
}).filter(function (item) {
  return !isNaN(item);
}).length;

In addition to bcrypt and PBKDF2 mentioned in other answers, I would recommend looking at scrypt

MD5 and SHA-1 are not recommended as they are relatively fast thus using "rent per hour" distributed computing (e.g. EC2) or a modern high end GPU one can "crack" passwords using brute force / dictionary attacks in relatively low costs and reasonable time.

If you must use them, then at least iterate the algorithm a predefined significant amount of times (1000+).

This is how I do it:

GROUP BY  EXTRACT(YEAR_MONTH FROM t.summaryDateTime);

If you are looking for TypeScript working functions then follow

public numericValue = (alphaChar: any) => alphaChar.toUpperCase().charCodeAt(0) - 64;

public alphaValue = (numericDigit: any) => 
   String.fromCharCode(64 + numericDigit) : '';

You can make several checks like (numericDigit >= 1 && numericDigit <= 26) ? inside function body as per the requirements.

Just ran into this again (certain I had before and came up with a less-than-satisfying solution).

For a tri-state boolean semantic (for example, using models.NullBooleanField), this works well:

{% if test.passed|lower == 'false' %} ... {% endif %}

Or if you prefer getting excited over the whole thing...

{% if test.passed|upper == 'FALSE' %} ... {% endif %}

Either way, this handles the special condition where you don't care about the None (evaluating to False in the if block) or True case.

The relationship Room to Class is considered weak (non-identifying) because the primary key components CID and DATE of entity Class doesn't contain the primary key RID of entity Room (in this case primary key of Room entity is a single component, but even if it was a composite key, one component of it also fulfills the condition).

However, for instance, in the case of the relationship Class and Class_Ins we see that is a strong (identifying) relationship because the primary key components EmpID and CID and DATE of Class_Ins contains a component of the primary key Class (in this case it contains both components CID and DATE).

Unwind segues are used to "go back" to some view controller from which, through a number of segues, you got to the "current" view controller.

Imagine you have something a MyNavController with A as its root view controller. Now you use a push segue to B. Now the navigation controller has A and B in its viewControllers array, and B is visible. Now you present C modally.

With unwind segues, you could now unwind "back" from C to B (i.e. dismissing the modally presented view controller), basically "undoing" the modal segue. You could even unwind all the way back to the root view controller A, undoing both the modal segue and the push segue.

Unwind segues make it easy to backtrack. For example, before iOS 6, the best practice for dismissing presented view controllers was to set the presenting view controller as the presented view controller’s delegate, then call your custom delegate method, which then dismisses the presentedViewController. Sound cumbersome and complicated? It was. That’s why unwind segues are nice.

Another simple way is to use a tuple:

// Declare a tuple type
let x: [string, number];
// Initialize it
x = ["hello", 10];
// Access elements
console.log("First: " + x["0"] + " Second: " + x["1"]);

Output:

First: hello Second: 10

Yes with the help of Arrays you can initialize array list in one line,

List<String> strlist= Arrays.asList("aaa", "bbb", "ccc");

From http://us3.php.net/manual/en/function.parse-url.php#93983

for some odd reason, parse_url returns the host (ex. example.com) as the path when no scheme is provided in the input url. So I've written a quick function to get the real host:

function getHost($Address) { 
   $parseUrl = parse_url(trim($Address)); 
   return trim($parseUrl['host'] ? $parseUrl['host'] : array_shift(explode('/', $parseUrl['path'], 2))); 
} 

getHost("example.com"); // Gives example.com 
getHost("http://example.com"); // Gives example.com 
getHost("www.example.com"); // Gives www.example.com 
getHost("http://example.com/xyz"); // Gives example.com

The error comes up when you are trying to assign a list of numpy array of different length to a data frame, and it can be reproduced as follows:

A data frame of four rows:

df = pd.DataFrame({'A': [1,2,3,4]})

Now trying to assign a list/array of two elements to it:

df['B'] = [3,4]   # or df['B'] = np.array([3,4])

Both errors out:

ValueError: Length of values does not match length of index

Because the data frame has four rows but the list and array has only two elements.

Work around Solution (use with caution): convert the list/array to a pandas Series, and then when you do assignment, missing index in the Series will be filled with NaN:

df['B'] = pd.Series([3,4])

df
#   A     B
#0  1   3.0
#1  2   4.0
#2  3   NaN          # NaN because the value at index 2 and 3 doesn't exist in the Series
#3  4   NaN

For your specific problem, if you don't care about the index or the correspondence of values between columns, you can reset index for each column after dropping the duplicates:

df.apply(lambda col: col.drop_duplicates().reset_index(drop=True))

#   A     B
#0  1   1.0
#1  2   5.0
#2  7   9.0
#3  8   NaN

use min rule

set first option value to 0

'selectName':{min:1}

Since so many people are referring to Raymond's talk, I'll just make it a little easier by writing down what he said:

The intention of the double underscores was not about privacy. The intention was to use it exactly like this

class Circle(object):

    def __init__(self, radius):
        self.radius = radius

    def area(self):
        p = self.__perimeter()
        r = p / math.pi / 2.0
        return math.pi * r ** 2.0

    def perimeter(self):
        return 2.0 * math.pi * self.radius

    __perimeter = perimeter  # local reference


class Tire(Circle):

    def perimeter(self):
        return Circle.perimeter(self) * 1.25

It's actually the opposite of privacy, it's all about freedom. It makes your subclasses free to override any one method without breaking the others.

Say you don't keep a local reference of perimeter in Circle. Now, a derived class Tire overrides the implementation of perimeter, without touching area. When you call Tire(5).area(), in theory it should still be using Circle.perimeter for computation, but in reality it's using Tire.perimeter, which is not the intended behavior. That's why we need a local reference in Circle.

But why __perimeter instead of _perimeter? Because _perimeter still gives derived class the chance to override:

class Tire(Circle):

    def perimeter(self):
        return Circle.perimeter(self) * 1.25

    _perimeter = perimeter

Double underscores has name mangling, so there's a very little chance that the local reference in parent class get override in derived class. thus "makes your subclasses free to override any one method without breaking the others".

If your class won't be inherited, or method overriding does not break anything, then you simply don't need __double_leading_underscore.

If you're on Mac, restarting the DNS responder fixed the issue for me.

sudo killall -HUP mDNSResponder

In MainViewController.m inside: - (void)viewWillAppear:(BOOL)animated add this:

//Lower screen 20px on ios 7
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) {
        CGRect viewBounds = [self.webView bounds];
        viewBounds.origin.y = 18;
        viewBounds.size.height = viewBounds.size.height - 18;
        self.webView.frame = viewBounds;
    }

so the end function will look like this:

- (void)viewWillAppear:(BOOL)animated
{
    // View defaults to full size.  If you want to customize the view's size, or its subviews (e.g. webView),
    // you can do so here.
    //Lower screen 20px on ios 7
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) {
        CGRect viewBounds = [self.webView bounds];
        viewBounds.origin.y = 18;
        viewBounds.size.height = viewBounds.size.height - 18;
        self.webView.frame = viewBounds;
    }
    [super viewWillAppear:animated];
}

You don't have a Date, you have a String representation of a date. You should convert the String into a Date and then obtain the milliseconds. To convert a String into a Date and vice versa you should use SimpleDateFormat class.

Here's an example of what you want/need to do (assuming time zone is not involved here):

String myDate = "2014/10/29 18:10:45";
SimpleDateFormat sdf = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
Date date = sdf.parse(myDate);
long millis = date.getTime();

Still, be careful because in Java the milliseconds obtained are the milliseconds between the desired epoch and 1970-01-01 00:00:00.

Using the new Date/Time API available since Java 8:

String myDate = "2014/10/29 18:10:45";
LocalDateTime localDateTime = LocalDateTime.parse(myDate,
    DateTimeFormatter.ofPattern("yyyy/MM/dd HH:mm:ss") );
/*
  With this new Date/Time API, when using a date, you need to
  specify the Zone where the date/time will be used. For your case,
  seems that you want/need to use the default zone of your system.
  Check which zone you need to use for specific behaviour e.g.
  CET or America/Lima
*/
long millis = localDateTime
    .atZone(ZoneId.systemDefault())
    .toInstant().toEpochMilli();

on osx log into your terminal and execute

sudo nano /opt/lampp/etc/extra/httpd-xampp.conf

and replace

<Directory "/opt/lampp/phpmyadmin">
    AllowOverride AuthConfig Limit
    Require local
    ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
</Directory>

with this

<Directory "/opt/lampp/phpmyadmin">
    AllowOverride AuthConfig Limit
    Order allow,deny
    Allow from all
    Require all granted
    ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
</Directory>

and then restart apache and mysql

or use this command

 /opt/lampp/xampp restart

it might save some time to somebody.

If you use GuzzleHttp and you face with this error message cURL error 60: SSL: no alternative certificate subject name matches target host name and you are fine with the 'insecure' solution (not recommended on production) then you have to add \GuzzleHttp\RequestOptions::VERIFY => false to the client configuration:

$this->client = new \GuzzleHttp\Client([
    'base_uri'                          => 'someAccessPoint',
    \GuzzleHttp\RequestOptions::HEADERS => [
        'User-Agent' => 'some-special-agent',
    ],
    'defaults'                          => [
        \GuzzleHttp\RequestOptions::CONNECT_TIMEOUT => 5,
        \GuzzleHttp\RequestOptions::ALLOW_REDIRECTS => true,
    ],
    \GuzzleHttp\RequestOptions::VERIFY  => false,
]);

which sets CURLOPT_SSL_VERIFYHOST to 0 and CURLOPT_SSL_VERIFYPEER to false in the CurlFactory::applyHandlerOptions() method

$conf[CURLOPT_SSL_VERIFYHOST] = 0;
$conf[CURLOPT_SSL_VERIFYPEER] = false;

From the GuzzleHttp documentation

verify

Describes the SSL certificate verification behavior of a request.

• Set to true to enable SSL certificate verification and use the default CA bundle > provided by operating system.
• Set to false to disable certificate verification (this is insecure!).
• Set to a string to provide the path to a CA bundle to enable verification using a custom certificate.

Wow, after few attempts I finally figured out how to deal with my text edits in vbs. The code works perfectly, it gives me the result I was expecting. Maybe it's not the best way to do this, but it does its job. Here's the code:

You should copy folder WebApplications from C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v12.0\ to C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v11.0\

Here I resolved this issue

The reason behind this issue is, there is already an application with the same package name in the phone, but you cannot find it in phone menu(U already made the un-installation but actually its still in your phone).

To see the application go to phones SETTINGS -> APPS. There you can see the application, but inside that the UNINSTALL button may be disabled. click on the menu overflow button to see Uninstall for all users.

After performed uninstalled for all users I have successfully installed my signed apk. You can also use adb to uninstall the app from phone.

adb uninstall package name

In addition to this, if your mobile supports multiple users then check if respective app is not installed for other users. If it is installed for others then first uninstall previous app and try again

If you are using Ubuntu/Linux:

sudo apt-get install libcurl4-openssl-dev libssl-dev

You cannot add a column with a default value in Hive. You have the right syntax for adding the column ALTER TABLE test1 ADD COLUMNS (access_count1 int);, you just need to get rid of default sum(max_count). No changes to that files backing your table will happen as a result of adding the column. Hive handles the "missing" data by interpreting NULL as the value for every cell in that column.

So now your have the problem of needing to populate the column. Unfortunately in Hive you essentially need to rewrite the whole table, this time with the column populated. It may be easier to rerun your original query with the new column. Or you could add the column to the table you have now, then select all of its columns plus value for the new column.

You also have the option to always COALESCE the column to your desired default and leave it NULL for now. This option fails when you want NULL to have a meaning distinct from your desired default. It also requires you to depend on always remembering to COALESCE.

If you are very confident in your abilities to deal with the files backing Hive, you could also directly alter them to add your default. In general I would recommend against this because most of the time it will be slower and more dangerous. There might be some case where it makes sense though, so I've included this option for completeness.

If you want to list last 3 chars, simplest way is

 select substr('123456',-3) from dual;

As mentioned by theoobe, some browsers do not close the websockets automatically. Don't try to handle any "close browser window" events client-side. There is currently no reliable way to do it, if you consider support of major desktop AND mobile browsers (e.g. onbeforeunload will not work in Mobile Safari). I had good experience with handling this problem server-side. E.g. if you use Java EE, take a look at javax.websocket.Endpoint, depending on the browser either the OnClose method or the OnError method will be called if you close/reload the browser window.

if you want saturday or sunday or any day of week but not exceeding current week(Sat-Sun) I got you covered with this piece of code.

public static DateTime GetDateInCurrentWeek(this DateTime date, DayOfWeek day)
{
    var temp = date;
    var limit = (int)date.DayOfWeek;
    var returnDate = DateTime.MinValue;

    if (date.DayOfWeek == day) return date;

    for (int i = limit; i < 6; i++)
    {
        temp = temp.AddDays(1);

        if (day == temp.DayOfWeek)
        {
            returnDate = temp;
            break;
        }
    }
    if (returnDate == DateTime.MinValue)
    {
        for (int i = limit; i > -1; i++)
        {
            date = date.AddDays(-1);

            if (day == date.DayOfWeek)
            {
                returnDate = date;
                break;
            }
        }
    }
    return returnDate;
}

Lists seem perfect for this purpose. For example within the function you would have

x = desired_return_value_1 # (vector, matrix, etc)

y = desired_return_value_2 # (vector, matrix, etc)

returnlist = list(x,y...)

}  # end of function

main program

x = returnlist[[1]]

y = returnlist[[2]]

push() is for arrays, not objects, so use the right data structure.

var data = [];
// ...
data[0] = { "ID": "1", "Status": "Valid" };
data[1] = { "ID": "2", "Status": "Invalid" };
// ...
var tempData = [];
for ( var index=0; index<data.length; index++ ) {
    if ( data[index].Status == "Valid" ) {
        tempData.push( data );
    }
}
data = tempData;

Maybe not the best solution, but it worked for me.

[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.VisualBasic")
$VBObject=[Microsoft.VisualBasic.Devices.ComputerInfo]::new()
$SystemMemory=$VBObject.TotalPhysicalMemory

#include has nothing to do with projects - it just tells the preprocessor "put the contents of the header file here". If you give it a path that points to the correct location (can be a relative path, like ../your_file.h) it will be included correctly.

You will, however, have to learn about libraries (static/dynamic libraries) in order to make such projects link properly - but that's another question.

For more generic advice on debugging this kind of problem MDN have a good article TypeError: "x" is not a function:

It was attempted to call a value like a function, but the value is not actually a function. Some code expects you to provide a function, but that didn't happen.

Maybe there is a typo in the function name? Maybe the object you are calling the method on does not have this function? For example, JavaScript objects have no map function, but JavaScript Array object do.

Basically the object (all functions in js are also objects) does not exist where you think it does. This could be for numerous reasons including(not an extensive list):

• Missing script library
• Typo
• The function is within a scope that you currently do not have access to, e.g.:

var x = function(){_x000D_
   var y = function() {_x000D_
      alert('fired y');_x000D_
   }_x000D_
};_x000D_
    _x000D_
//the global scope can't access y because it is closed over in x and not exposed_x000D_
//y is not a function err triggered_x000D_
x.y();

• Your object/function does not have the function your calling:

var x = function(){_x000D_
   var y = function() {_x000D_
      alert('fired y');_x000D_
   }_x000D_
};_x000D_
    _x000D_
//z is not a function error (as above) triggered_x000D_
x.z();

Without reloading, using HTML and PHP only it is not possible, but this can be very similar to what you want, but you have to reload:

<?php
    function test() {
        echo $_POST["user"];
    }

    if (isset($_POST[])) { // If it is the first time, it does nothing
        test();
    }
?>

<form action="test.php" method="post">
    <input type="text" name="user" placeholder="enter a text" />
    <input type="submit" value="submit" onclick="test()" />
</form>

With your own Code and a Slight Change withou jQuery,

function testingAPI(){ 
    var key = "8a1c6a354c884c658ff29a8636fd7c18"; 
    var url = "https://api.fantasydata.net/nfl/v2/JSON/PlayerSeasonStats/2015";
    console.log(httpGet(url,key)); 
}


function httpGet(url,key){
    var xmlHttp = new XMLHttpRequest();
    xmlHttp.open( "GET", url, false );
    xmlHttp.setRequestHeader("Ocp-Apim-Subscription-Key",key);
    xmlHttp.send(null);
    return xmlHttp.responseText;
}

Thank You

Using:

@ComponentScan
@EnableAutoConfiguration
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);  

        //do your ReconTool stuff
    }
}

will work in all circumstances. Whether you want to launch the application from the IDE, or the build tool.

Using maven just use mvn spring-boot:run

while in gradle it would be gradle bootRun

An alternative to adding code under the run method, is to have a Spring Bean that implements CommandLineRunner. That would look like:

@Component
public class ReconTool implements CommandLineRunner {

    @Override
    public void run(String... args) throws Exception {
       //implement your business logic here
    }
}

Check out this guide from Spring's official guide repository.

The full Spring Boot documentation can be found here

There is the nuclear approach which is in your App.css (or counterpart)

a{
  text-decoration: none;
}

which prevents underline for all <a> tags which is the root cause of this problem

Only call time pass-by-reference is removed. So change:

call_user_func($func, &$this, &$client ...

To this:

call_user_func($func, $this, $client ...

&$this should never be needed after PHP4 anyway period.

If you absolutely need $client to be passed by reference, update the function ($func) signature instead (function func(&$client) {)

I was just having the same issue with ReSharper 8.2 in Visual Studio 2013, and none of the usual solutions here of clearing caches, suspending ReSharper or re-installing ReSharper was working.

In my case I ended up solving it as follows... I looked at one of the symbols that it couldn't resolve and noted it was in System.Web.Http.dll. I then found that this was in the Microsoft.AspNet.WebApi.Core NuGet package. I used the package manager console to try and uninstall that package, except of course it told me that it couldn't due to other dependencies.

So I uninstalled each dependency up to and including Microsoft.AspNet.WebApi.Core, and then re-installed each package again in the reverse order. ReSharper picked everything up correctly as it was installed, and now seems fine.

Use

var value = "" + 5 + 6;

to force it to strings.

To even do better boolean mapping to Y/N, add to your hibernate configuration:

<!-- when using type="yes_no" for booleans, the line below allow booleans in HQL expressions: -->
<property name="hibernate.query.substitutions">true 'Y', false 'N'</property>

Now you can use booleans in HQL, for example:

"FROM " + SomeDomainClass.class.getName() + " somedomainclass " +
"WHERE somedomainclass.someboolean = false"

if it was bad practice "pass" would not be an option. if you have an asset that receives information from many places IE a form or userInput it comes in handy.

variable = False
try:
    if request.form['variable'] == '1':
       variable = True
except:
    pass

The only way to ensure code is executed is to place your setTimeout logic in a different process.

Use the child process module to spawn a new node.js program that does your logic and pass data to that process through some kind of a stream (maybe tcp).

This way even if some long blocking code is running in your main process your child process has already started itself and placed a setTimeout in a new process and a new thread and will thus run when you expect it to.

Further complication are at a hardware level where you have more threads running then processes and thus context switching will cause (very minor) delays from your expected timing. This should be neglible and if it matters you need to seriously consider what your trying to do, why you need such accuracy and what kind of real time alternative hardware is available to do the job instead.

In general using child processes and running multiple node applications as separate processes together with a load balancer or shared data storage (like redis) is important for scaling your code.

You should be able to use OrderBy in LINQ...

var sortedItems = myList.OrderBy(s => s);

1) Members of a class are private by default and members of struct are public by default.

For example program 1 fails in compilation and program 2 works fine.

// Program 1
#include <stdio.h>

class Test {
    int x; // x is private
};
int main()
{
  Test t;
  t.x = 20; // compiler error because x is private
  getchar();
  return 0;
}
Run on IDE
// Program 2
#include <stdio.h>

struct Test {
    int x; // x is public
};
int main()
{
  Test t;
  t.x = 20; // works fine because x is public
  getchar();
  return 0;
}

2) When deriving a struct from a class/struct, default access-specifier for a base class/struct is public. And when deriving a class, default access specifier is private.

For example program 3 fails in compilation and program 4 works fine.

// Program 3
#include <stdio.h>

class Base {
public:
    int x;
};

class Derived : Base { }; // is equilalent to class Derived : private Base {}

int main()
{
  Derived d;
  d.x = 20; // compiler error becuase inheritance is private
  getchar();
  return 0;
}
Run on IDE
// Program 4
#include <stdio.h>

class Base {
public:
    int x;
};

struct Derived : Base { }; // is equilalent to struct Derived : public Base {}

int main()
{
  Derived d;
  d.x = 20; // works fine becuase inheritance is public
  getchar();
  return 0;
}

You need to set a height on the DIV. Otherwise it will keep expanding indefinitely.

You simply need to enclose your SELECT statements in parentheses to indicate that they are subqueries:

SET cityLat = (SELECT cities.lat FROM cities WHERE cities.id = cityID);

Alternatively, you can use MySQL's SELECT ... INTO syntax. One advantage of this approach is that both cityLat and cityLng can be assigned from a single table-access:

SELECT lat, lng INTO cityLat, cityLng FROM cities WHERE id = cityID;

However, the entire procedure can be replaced with a single self-joined SELECT statement:

SELECT   b.*, HAVERSINE(a.lat, a.lng, b.lat, b.lng) AS dist
FROM     cities AS a, cities AS b
WHERE    a.id = cityID
ORDER BY dist
LIMIT    10;

You'll have to use JS to open the popup, though you can put it on the page conditionally with PHP, you're right that you'll have to use a JavaScript function.

In my case the source file has windows-1250 encoding and iconv prints tons of notices about illegal characters in input string...

So this solution helped me a lot:

/**
 * getting CSV array with UTF-8 encoding
 *
 * @param   resource    &$handle
 * @param   integer     $length
 * @param   string      $separator
 *
 * @return  array|false
 */
private function fgetcsvUTF8(&$handle, $length, $separator = ';')
{
    if (($buffer = fgets($handle, $length)) !== false)
    {
        $buffer = $this->autoUTF($buffer);
        return str_getcsv($buffer, $separator);
    }
    return false;
}

/**
 * automatic convertion windows-1250 and iso-8859-2 info utf-8 string
 *
 * @param   string  $s
 *
 * @return  string
 */
private function autoUTF($s)
{
    // detect UTF-8
    if (preg_match('#[\x80-\x{1FF}\x{2000}-\x{3FFF}]#u', $s))
        return $s;

    // detect WINDOWS-1250
    if (preg_match('#[\x7F-\x9F\xBC]#', $s))
        return iconv('WINDOWS-1250', 'UTF-8', $s);

    // assume ISO-8859-2
    return iconv('ISO-8859-2', 'UTF-8', $s);
}

Response to @manvel's answer - use str_getcsv instead of explode - because of cases like this:

some;nice;value;"and;here;comes;combinated;value";and;some;others

explode will explode string into parts:

some
nice
value
"and
here
comes
combinated
value"
and
some
others

but str_getcsv will explode string into parts:

some
nice
value
and;here;comes;combinated;value
and
some
others

I am generating csv files from a simple C# application and had the same problem. My solution was to ensure the file is written with UTF8 encoding, like so:

// Use UTF8 encoding so that Excel is ok with accents and such.
using (StreamWriter writer = new StreamWriter(path, false, Encoding.UTF8))
{
    SaveCSV(writer);
}

I originally had the following code, with which accents look fine in Notepad++ but were getting mangled in Excel:

using (StreamWriter writer = new StreamWriter(path))
{
    SaveCSV(writer);
}

Your mileage may vary - I'm using .NET 4 and Excel from Office 365.

git clean -fd

didn't help, new files remained. What I did is totally deleting all the working tree and then

git reset --hard

See "How do I clear my local working directory in git?" for advice to add the -x option to clean:

git clean -fdx

Note -x flag will remove all files ignored by Git so be careful (see discussion in the answer I refer to).

I'm not familiar with either of these books, but the second is closer to current reality. The first may be discussing a specific processor.

Processors have been made with quite a variety of word sizes, not always a multiple of 8.

The 8086 and 8087 processors used 16 bit words, and it's likely this is the machine the first author was writing about.

More recent processors commonly use 32 or 64 bit words.

In the 50's and 60's there were machines with words sizes that seem quite strange to us now, such as 4, 9 and 36. Since about the 70's word size has commonly been a power of 2 and a multiple of 8.

You're after the zip function.

Taken directly from the question: How to merge lists into a list of tuples in Python?

>>> list_a = [1, 2, 3, 4]
>>> list_b = [5, 6, 7, 8]
>>> zip(list_a,list_b)
[(1, 5), (2, 6), (3, 7), (4, 8)]

easy way is:

a = [1,2]
d = {}
for i in a:
  d[i]=[i, ]

print(d)
{'1': [1, ], '2':[2, ]}
