I just had the same problem and the same message. I was able to get it fixed by importing to the Java Building Path the hamcrest-all-1.3.jar archive. I'm using a JUnit 4.12 version.

Please add the keyword public to your class definition. Your test class is currently not visible outside its own assembly.

namespace tests {
    [TestClass]
    public class SimpleTest {
        [TestMethod]
        public void Test() {
            Assert.AreEqual("a","a", "same");
        }
    }
}

You can search in windows by DOS and explorer GUI.

DOS:

1) DIR

2) ICACLS (searches for files and folders to set ACL on them)

3) cacls ..................................................

2) example

icacls c:*ntoskrnl*.* /grant system:(f) /c /t ,then use PMON from sysinternals to monitor what folders are denied accesss. The result contains

access path contains your drive

process name is explorer.exe

those were filters youu must apply

Another possibility with Guava:

dependency: compile 'com.google.guava:guava:11.0.2'

import com.google.common.io.ByteStreams;
...

String total = new String(ByteStreams.toByteArray(inputStream ));

If you have empty rows, not NAs, you can do:

data[!apply(data == "", 1, all),]

To remove both (NAs and empty):

data <- data[!apply(is.na(data) | data == "", 1, all),]

The runas command does not allow a password on its command line. This is by design (and also the reason you cannot pipe a password to it as input). Raymond Chen says it nicely:

The RunAs program demands that you type the password manually. Why doesn't it accept a password on the command line?

This was a conscious decision. If it were possible to pass the password on the command line, people would start embedding passwords into batch files and logon scripts, which is laughably insecure.

In other words, the feature is missing to remove the temptation to use the feature insecurely.

$("#co").click(function(){
   $(this).css({"backgroundColor" : "blue"});
});

Although this code is likely beyond the understanding of a novice, it can be done in one line using a regex with positive and negative look-aheads:

boolean ok = 
    password.matches("^(?=.*[A-Z])(?=.*[!@#$%^&*])(?=.*\\d)(?!.*(AND|NOT)).*[a-z].*");

Regarding the first question: What are the scenarios where a process gets a SIGABRT in C++?

I can think of two special cases where a C++ program is aborted automatically -- not by directly calling std::abort() or std::terminate():

One: Throw an exception while an exception is being handled.

try {
    throw "abc";
}
catch (...) {
    throw "def";  // abort here
}

Two: An uncaught exception that attempts to propagates outside main().

int main(int argc, char** argv)
{
    throw "abc";  // abort here
}

C++ experts could probably name more special cases.

There is also a lot of good info on these reference pages:

• https://en.cppreference.com/w/cpp/utility/program/abort
• https://en.cppreference.com/w/cpp/error/terminate

PHP, by default, always returns the following header: "Content-Type: text/html" (notice no charset), therefore you must use

<?php header('Content-type: text/plain; charset=utf-8'); ?>

Setting the JAVA_HOME, CATALINA_HOME Environment Variable on Windows

One can do using command prompt:

1. set JAVA_HOME=C:\ "top level directory of your java install"
2. set CATALINA_HOME=C:\ "top level directory of your Tomcat install"
3. set PATH=%PATH%;%JAVA_HOME%\bin;%CATALINA_HOME%\bin

OR you can do the same:

1. Go to system properties
2. Go to environment variables and add a new variable with the name JAVA_HOME and provide variable value as C:\ "top level directory of your java install"
3. Go to environment variables and add a new variable with the name CATALINA_HOME and provide variable value as C:\ "top level directory of your Tomcat install"
4. In path variable add a new variable value as ;%CATALINA_HOME%\bin;

!members.find()

I think now the best way to solve this issue is code above. It works since Groovy 1.8.1 http://docs.groovy-lang.org/docs/next/html/groovy-jdk/java/util/Collection.html#find(). Examples:

def lst1 = []
assert !lst1.find()

def lst2 = [null]
assert !lst2.find()

def lst3 = [null,2,null]
assert lst3.find()

def lst4 = [null,null,null]
assert !lst4.find()

def lst5 = [null, 0, 0.0, false, '', [], 42, 43]
assert lst5.find() == 42

def lst6 = null; 
assert !lst6.find()

opt is new for ruby 1.9. The various options are documented in IO.new : www.ruby-doc.org/core/IO.html

You could create a little class that returns the boolean result of calling match, and retains the matched groups for subsequent retrieval:

import re

class REMatcher(object):
    def __init__(self, matchstring):
        self.matchstring = matchstring

    def match(self,regexp):
        self.rematch = re.match(regexp, self.matchstring)
        return bool(self.rematch)

    def group(self,i):
        return self.rematch.group(i)


for statement in ("I love Mary", 
                  "Ich liebe Margot", 
                  "Je t'aime Marie", 
                  "Te amo Maria"):

    m = REMatcher(statement)

    if m.match(r"I love (\w+)"): 
        print "He loves",m.group(1) 

    elif m.match(r"Ich liebe (\w+)"):
        print "Er liebt",m.group(1) 

    elif m.match(r"Je t'aime (\w+)"):
        print "Il aime",m.group(1) 

    else: 
        print "???"

Update for Python 3 print as a function, and Python 3.8 assignment expressions - no need for a REMatcher class now:

import re

for statement in ("I love Mary",
                  "Ich liebe Margot",
                  "Je t'aime Marie",
                  "Te amo Maria"):

    if m := re.match(r"I love (\w+)", statement):
        print("He loves", m.group(1))

    elif m := re.match(r"Ich liebe (\w+)", statement):
        print("Er liebt", m.group(1))

    elif m := re.match(r"Je t'aime (\w+)", statement):
        print("Il aime", m.group(1))

    else:
        print()

Someone give Luciano these points :) I just tested his answer -had a similar question- and worked perfectly...

I even add my 50 cents:

.error(function(jqXHR, textStatus, errorThrown) {
        console.log("error " + textStatus);
        console.log("incoming Text " + jqXHR.responseText);
    })

Another way besides @Nahush's answer, if you are already using Express framework in the project then you can avoid using Nginx for reverse-proxy.

A simpler way is to use express-http-proxy

1. run npm run build to create the bundle.

   var proxy = require('express-http-proxy');
   
   var app = require('express')();
   
   //define the path of build
   
   var staticFilesPath = path.resolve(__dirname, '..', 'build');
   
   app.use(express.static(staticFilesPath));
   
   app.use('/api/api-server', proxy('www.api-server.com'));
   

Use "/api/api-server" from react code to call the API.

So, that browser will send request to the same host which will be internally redirecting the request to another server and the browser will feel that It is coming from the same origin ;)

To use shorthand to get the direction:

int direction = column == 0
                ? 0
                : (column == _gridSize - 1 ? 1 : rand.Next(2));

To simplify the code entirely:

if (column == gridSize - 1 || rand.Next(2) == 1)
{
}
else
{
}

This worked for me.

Single-clicking a row triggers the code-behind.

XAML:

<ListView x:Name="MyListView" MouseLeftButtonUp="MyListView_MouseLeftButtonUp">
    <GridView>
        <!-- Declare GridViewColumns. -->
    </GridView>
</ListView.View>

Code-behind:

private void MyListView_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
{
    System.Windows.Controls.ListView list = (System.Windows.Controls.ListView)sender;
    MyClass selectedObject = (MyClass)list.SelectedItem;
    // Do stuff with the selectedObject.
}

Limit - 30 symbols. Username must contains only letters, numbers, periods and underscores.

Your __autoload function will receive the full class-name, including the namespace name.

This means, in your case, the __autoload function will receive 'Person\Barnes\David\Class1', and not only 'Class1'.

So, you have to modify your autoloading code, to deal with that kind of "more-complicated" name ; a solution often used is to organize your files using one level of directory per "level" of namespaces, and, when autoloading, replace '\' in the namespace name by DIRECTORY_SEPARATOR.

declare @OrderByCmd  nvarchar(2000)
declare @OrderByName nvarchar(100)
declare @OrderByCity nvarchar(100)
set @OrderByName='Name'    
set @OrderByCity='city'
set @OrderByCmd= 'select * from customer Order By '+@OrderByName+','+@OrderByCity+''
EXECUTE sp_executesql @OrderByCmd 

You could also try:

if ((!isset($action)) || !($action == "add" || $action == "delete")) {
  // Do your stuff
}

It's a reserved keyword (like return, filter, function, break).

Reference

Also, as per Section 7.6.4 of Bruce Payette's Powershell in Action:

But what happens when you want a script to exit from within a function defined in that script? ... To make this easier, Powershell has the exit keyword.

Of course, as other have pointed out, it's not hard to do what you want by wrapping exit in a function:

PS C:\> function ex{exit}
PS C:\> new-alias ^D ex

Bind the button, this is done with jQuery:

$("#my-table input[type='button']").click(function(){
    var parameter = $(this).val();
    window.location = "http://yoursite.com/page?variable=" + parameter;
});

If you want to get classes of div and then want to check if any class exists then simple use.

if ( $('#div-id' ).hasClass( 'classname' ) ) {
    // do something...
}

e.g;

if ( $('body').hasClass( 'home' ) ) {
    $('#menu-item-4').addClass('active');
}

In ASCII the upper and lower case alphabet is 0x20 (in ASCII 0x20 is space ' ') apart from each other, so this is another way to do it.

As already stated, log4j.properties should be in a directory included in the classpath, I want to add that in a mavenized project a good place can be src/main/resources/log4j.properties

Try svn revert filename for every file you don't need and haven't yet committed. Or alternatively do svn revert -R folder for the problematic folder and then re-do the operation with correct ignoring configuration.

From the documentation:

 you can undo any scheduling operations:

$ svn add mistake.txt whoops
A         mistake.txt
A         whoops
A         whoops/oopsie.c

$ svn revert mistake.txt whoops
Reverted mistake.txt
Reverted whoops

Changing from https:// to http:// worked for me

This is how I do it in FreeBSD:

#!/usr/local/bin/bash
for i in $(ipcs -a | grep "^s" | awk '{ print $2 }');
do
        echo "ipcrm -s $i"
        ipcrm -s $i
done

You can set the ReadOnly property to true.

Quoth the link:

When this property is set to true, the contents of the control cannot be changed by the user at runtime. With this property set to true, you can still set the value of the Text property in code. You can use this feature instead of disabling the control with the Enabled property to allow the contents to be copied and ToolTips to be shown.

A simple approach which returns a string with ip-addresses for the interfaces is:

from subprocess import check_output

ips = check_output(['hostname', '--all-ip-addresses'])

for more info see hostname.

Assuming you have the sdk extracted at ~/Android/Sdk,

export ANDROID_HOME=$HOME/Android/Sdk
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/platform-tools

1. Add the above lines to the file ~/.bashrc (located at home/username/.bashrc) to make it permanent for the current user. Run source ~/.bashrc to apply the changes or restart your terminal.

   (or)

2. Run the above lines on a terminal window to make it available for the session.

To test if you have set it up correctly,

Run the below commands on a terminal window

1. echo $ANDROID_HOME

   user@host:~$ echo $ANDROID_HOME
   /home/<user>/Android/Sdk
   

2. which android

   user@host:~$ which android
   /home/<user>/Android/Sdk/tools/android
   

3. Run android on a terminal window, If it opens up Android SDK Manager, you are good to go.

$id = strrchr($url,"/");

Hope that's useful!

You can assign default parameter values inline when you first create the mixin:

@mixin clearfix($width: 'auto') {

  @if $width == 'auto' {

    // if width is not passed, or empty do this

  } @else {

    display: inline-block;
    width: $width;

  }
}

You need to add it to an axes. A Circle is a subclass of an Patch, and an axes has an add_patch method. (You can also use add_artist but it's not recommended.)

Here's an example of doing this:

import matplotlib.pyplot as plt

circle1 = plt.Circle((0, 0), 0.2, color='r')
circle2 = plt.Circle((0.5, 0.5), 0.2, color='blue')
circle3 = plt.Circle((1, 1), 0.2, color='g', clip_on=False)

fig, ax = plt.subplots() # note we must use plt.subplots, not plt.subplot
# (or if you have an existing figure)
# fig = plt.gcf()
# ax = fig.gca()

ax.add_patch(circle1)
ax.add_patch(circle2)
ax.add_patch(circle3)

fig.savefig('plotcircles.png')

This results in the following figure:

The first circle is at the origin, but by default clip_on is True, so the circle is clipped when ever it extends beyond the axes. The third (green) circle shows what happens when you don't clip the Artist. It extends beyond the axes (but not beyond the figure, ie the figure size is not automatically adjusted to plot all of your artists).

The units for x, y and radius correspond to data units by default. In this case, I didn't plot anything on my axes (fig.gca() returns the current axes), and since the limits have never been set, they defaults to an x and y range from 0 to 1.

Here's a continuation of the example, showing how units matter:

circle1 = plt.Circle((0, 0), 2, color='r')
# now make a circle with no fill, which is good for hi-lighting key results
circle2 = plt.Circle((5, 5), 0.5, color='b', fill=False)
circle3 = plt.Circle((10, 10), 2, color='g', clip_on=False)
    
ax = plt.gca()
ax.cla() # clear things for fresh plot

# change default range so that new circles will work
ax.set_xlim((0, 10))
ax.set_ylim((0, 10))
# some data
ax.plot(range(11), 'o', color='black')
# key data point that we are encircling
ax.plot((5), (5), 'o', color='y')
    
ax.add_patch(circle1)
ax.add_patch(circle2)
ax.add_patch(circle3)
fig.savefig('plotcircles2.png')

which results in:

You can see how I set the fill of the 2nd circle to False, which is useful for encircling key results (like my yellow data point).

Store your files in public/images directory.

In my case, the request type was wrong. I was using GET(dumb) It must be PUT.

First thing to understand is that the RequestMapping#produces() element in

@RequestMapping(value = "/json", method = RequestMethod.GET, produces = "application/json")

serves only to restrict the mapping for your request handlers. It does nothing else.

Then, given that your method has a return type of String and is annotated with @ResponseBody, the return value will be handled by StringHttpMessageConverter which sets the Content-type header to text/plain. If you want to return a JSON string yourself and set the header to application/json, use a return type of ResponseEntity (get rid of @ResponseBody) and add appropriate headers to it.

@RequestMapping(value = "/json", method = RequestMethod.GET, produces = "application/json")
public ResponseEntity<String> bar() {
    final HttpHeaders httpHeaders= new HttpHeaders();
    httpHeaders.setContentType(MediaType.APPLICATION_JSON);
    return new ResponseEntity<String>("{\"test\": \"jsonResponseExample\"}", httpHeaders, HttpStatus.OK);
}

Note that you should probably have

<mvc:annotation-driven /> 

in your servlet context configuration to set up your MVC configuration with the most suitable defaults.

Python is only a language, to get GET and POST data, you need a web framework or toolkit written in Python. Django is one, as Charlie points out, the cgi and urllib standard modules are others. Also available are Turbogears, Pylons, CherryPy, web.py, mod_python, fastcgi, etc, etc.

In Django, your view functions receive a request argument which has request.GET and request.POST. Other frameworks will do it differently.

Let's say you have 25 objects and want one process to handle any one objects click event. You could write 25 delegates or use a loop to handle the click event.

public form1()
{
    foreach (Panel pl  in Container.Components)
    {
        pl.Click += Panel_Click;
    }
}

private void Panel_Click(object sender, EventArgs e)
{
    // Process the panel clicks here
    int index = Panels.FindIndex(a => a == sender);
    ...
}

Function convert image to base64 using jquery (you can convert to vanila js). Hope it help to you!

Usage: input is your nameId input has file image

    return new Promise(resolve => {
      reader.onload = ev => {
        resolve(ev.target.result)
      }
      reader.readAsDataURL(image[0])
    })
  }
}

async function proccessData() {
  const image = await converImageToBase64('asd')
  console.log(image)
}

• As of Apr 2013, it is possible to delete App IDs.
• As of Sep 2013, it is impossible to delete App IDs again after the big outage. I hope Apple will put it back.
• As of mid 2014, it is possible to delete App IDs again. However, you can't delete id of apps existing in the App Store.

What I do when I wonder something like the question asked here is go to the source.

toBe()

expect().toBe() is defined as:

function toBe() {
  return {
    compare: function(actual, expected) {
      return {
        pass: actual === expected
      };
    }
  };
}

It performs its test with === which means that when used as expect(foo).toBe(true), it will pass only if foo actually has the value true. Truthy values won't make the test pass.

toBeTruthy()

expect().toBeTruthy() is defined as:

function toBeTruthy() {
  return {
    compare: function(actual) {
      return {
        pass: !!actual
      };
    }
  };
}

Type coercion

A value is truthy if the coercion of this value to a boolean yields the value true. The operation !! tests for truthiness by coercing the value passed to expect to a boolean. Note that contrarily to what the currently accepted answer implies, == true is not a correct test for truthiness. You'll get funny things like

> "hello" == true
false
> "" == true
false
> [] == true
false
> [1, 2, 3] == true
false

Whereas using !! yields:

> !!"hello"
true
> !!""
false
> !![1, 2, 3]
true
> !![] 
true

(Yes, empty or not, an array is truthy.)

toBeTrue()

expect().toBeTrue() is part of Jasmine-Matchers (which is registered on npm as jasmine-expect after a later project registered jasmine-matchers first).

expect().toBeTrue() is defined as:

function toBeTrue(actual) {
  return actual === true ||
    is(actual, 'Boolean') &&
    actual.valueOf();
}

The difference with expect().toBeTrue() and expect().toBe(true) is that expect().toBeTrue() tests whether it is dealing with a Boolean object. expect(new Boolean(true)).toBe(true) would fail whereas expect(new Boolean(true)).toBeTrue() would pass. This is because of this funny thing:

> new Boolean(true) === true
false
> new Boolean(true) === false
false

At least it is truthy:

> !!new Boolean(true)
true

Which is best suited for use with elem.isDisplayed()?

Ultimately Protractor hands off this request to Selenium. The documentation states that the value produced by .isDisplayed() is a promise that resolves to a boolean. I would take it at face value and use .toBeTrue() or .toBe(true). If I found a case where the implementation returns truthy/falsy values, I would file a bug report.

Incremental development means that different parts of a software project are continuously integrated into the whole, instead of a monolithic approach where all the different parts are assembled in one or a few milestones of the project.

Iterative means that once a first version of a component is complete it is tested, reviewed and the results are almost immediately transformed into a new version (iteration) of this component.

So as a first result: iterative development doesn't need to be incremental and vice versa, but these methods are a good fit.

Agile development aims to reduce massive planing overhead in software projects to allow fast reactions to change e.g. in customer wishes. Incremental and iterative development are almost always part of an agile development strategy. There are several approaches to Agile development (e.g. scrum).

You can also use inspect.getdoc. It cleans up the __doc__ by normalizing tabs to spaces and left shifting the doc body to remove common leading spaces.

Since the existing answers were written, Xcode's interface has been updated and they're no longer correct (notably the Click on Window, Organiser // Expand the Teams section step). Now the instructions for importing an existing certificate are as follows:

To export selected certificates

1. Choose Xcode > Preferences.
2. Click Accounts at the top of the window.
3. Select the team you want to view, and click View Details.
4. Control-click the certificate you want to export in the Signing Identities table and choose Export from the pop-up menu.

5. Enter a filename in the Save As field and a password in both the Password and Verify fields. The file is encrypted and password protected.
6. Click Save. The file is saved to the location you specified with a .p12 extension.

Source (Apple's documentation)

To import it, I found that Xcode's let-me-help-you menu didn't recognise the .p12 file. Instead, I simply imported it manually into Keychain, then Xcode built and archived without complaining.

I used the RowHeight property of a range (which means cells as well). If it's zero then it's hidden. So just loop through all rows as you would normally but in the if condition check for that property as in If myRange.RowHeight > 0 then DoStuff where DoStuff is something you want to do with the visible cells.

the :checked pseudo-class initially applies to such elements that have the HTML4 selected and checked attributes

So, this CSS works, although styling the color is not possible in every browser:

option:checked { color: red; }

An example of this in action, hiding the currently selected item from the drop down list.

option:checked { display:none; }

<select>_x000D_
    <option>A</option>_x000D_
    <option>B</option>_x000D_
    <option>C</option>_x000D_
</select>

To style the currently selected option in the closed dropdown as well, you could try reversing the logic:

select { color: red; }
option:not(:checked) { color: black; } /* or whatever your default style is */

You can also initialise it like this:

struct name sara = { "Sara", "Black" };

Since (as a special case) you're allowed to initialise char arrays from string constants.

Now, as for what a struct actually is - it's a compound type composed of other values. What sara actually looks like in memory is a block of 20 consecutive char values (which can be referred to using sara.first, followed by 0 or more padding bytes, followed by another block of 20 consecutive char values (which can be referred to using sara.last). All other instances of the struct name type are laid out in the same way.

In this case, it is very unlikely that there is any padding, so a struct name is just a block of 40 characters, for which you have a name for the first 20 and the last 20.

You can find out how big a block of memory a struct name takes using sizeof(struct name), and you can find out where within that block of memory each member of the structure is placed at using offsetof(struct name, first) and offsetof(struct name, last).

Getting started

Add these lines to build.gradle.

dependencies {
    compile 'com.h6ah4i.android.widget.verticalseekbar:verticalseekbar:0.7.2'
}

Usage

Java code

public class TestVerticalSeekbar extends AppCompatActivity {
    private SeekBar volumeControl = null;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_test_vertical_seekbar);

        volumeControl = (SeekBar) findViewById(R.id.mySeekBar);

        volumeControl.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
            int progressChanged = 0;

            public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
                progressChanged = progress;
            }

            public void onStartTrackingTouch(SeekBar seekBar) {
                // TODO Auto-generated method stub
            }

            public void onStopTrackingTouch(SeekBar seekBar) {
                Toast.makeText(getApplicationContext(), "seek bar progress:" + progressChanged,
                        Toast.LENGTH_SHORT).show();
            }
        });
    }

}

Layout XML

<!-- This library requires pair of the VerticalSeekBar and VerticalSeekBarWrapper classes -->
<com.h6ah4i.android.widget.verticalseekbar.VerticalSeekBarWrapper
    android:layout_width="wrap_content"
    android:layout_height="150dp">
    <com.h6ah4i.android.widget.verticalseekbar.VerticalSeekBar
        android:id="@+id/mySeekBar"

NOTE: android:splitTrack="false" is required for Android N+.

Httplib seems like a cleaner choice.

import httplib
connection =  httplib.HTTPConnection('1.2.3.4:1234')
body_content = 'BODY CONTENT GOES HERE'
connection.request('PUT', '/url/path/to/put/to', body_content)
result = connection.getresponse()
# Now result.status and result.reason contains interesting stuff

$myArray = array(
    2 => '3th element',
    4 => 'first element',
    1 => 'second element',
    3 => '4th element'
);
echo min(array_keys($myArray)); // return 1

This is how to set an image into ImageView using the setImageResource() method:

ImageView myImageView = (ImageView)v.findViewById(R.id.img_play);
// supossing to have an image called ic_play inside my drawables.
myImageView.setImageResource(R.drawable.ic_play);

Once you have done your processing in the selectFunction() you could do the following

document.getElementById('select').selectedIndex = 0;
document.getElementById('select').value = 'Default';

Another way (Using Formulas in VBA). I guess this is the shortest VBA code as well?

Sub Sample()
    Dim ws As Worksheet
    Dim lRow As Long

    Set ws = ThisWorkbook.Sheets("Sheet1")

    With ws
        lRow = .Range("A" & .Rows.Count).End(xlUp).Row

        .Range("B1:B" & lRow).Formula = "=If(A1<>"""",""My Text"","""")"
        .Range("B1:B" & lRow).Value = .Range("B1:B" & lRow).Value
    End With
End Sub

parseInt provides integers when the string begins with the representation of an integer:

(parseInt '1a')  is  1

..so perhaps:

isInteger = (s)->
  s is (parseInt s).toString()  and  s isnt 'NaN'

(isInteger 'a') is false
(isInteger '1a') is false
(isInteger 'NaN') is false
(isInteger '-42') is true

Pardon my CoffeeScript.

see docs: http://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.insert.html

using loc = 0 will insert at the beginning

df.insert(loc, column, value)

df = pd.DataFrame({'B': [1, 2, 3], 'C': [4, 5, 6]})

df

   B  C
0  1  4
1  2  5

idx = 0
new_col = [7, 8, 9]  # can be a list, a Series, an array or a scalar   
df.insert(loc=idx, column='A', value=new_col)

The usual method I have seen is X.Y.Z, which generally corresponds to major.minor.patch:

• Major version numbers change whenever there is some significant change being introduced. For example, a large or potentially backward-incompatible change to a software package.
• Minor version numbers change when a new, minor feature is introduced or when a set of smaller features is rolled out.
• Patch numbers change when a new build of the software is released to customers. This is normally for small bug-fixes or the like.

Other variations use build numbers as an additional identifier. So you may have a large number for X.Y.Z.build if you have many revisions that are tested between releases. I use a couple of packages that are identified by year/month or year/release. Thus, a release in the month of September of 2010 might be 2010.9 or 2010.3 for the 3rd release of this year.

There are many variants to versioning. It all boils down to personal preference.

For the "1.3v1.1", that may be two different internal products, something that would be a shared library / codebase that is rev'd differently from the main product; that may indicate version 1.3 for the main product, and version 1.1 of the internal library / package.

Just complementing: It's kind of obvious, but you can use static imports to give you a hand, like this:

import static javax.swing.JOptionPane.*;

public class SimpleDialog(){
    public static void main(String argv[]) {
        showMessageDialog(null, "Message", "Title", ERROR_MESSAGE);
    }
}

The most famous library to create some GUI in C language is certainly GTK.

With this library you can easily create some buttons (for your example). When a user clicks on the button, a signal is emitted and you can write a handler to do some actions.

To change only "background" (add corners, change color, ....) you can put it into FrameLayout with wanted background drawable, else you need to make nine patch background for to not lose spinner arrow. Spinner background is transparent.

You have a tuple of tuples.
To convert every tuple to a list:

[list(i) for i in level] # list of lists

--- OR ---

map(list, level)

And after you are done editing, just convert them back:

tuple(tuple(i) for i in edited) # tuple of tuples

--- OR --- (Thanks @jamylak)

tuple(itertools.imap(tuple, edited))

You can also use a numpy array:

>>> a = numpy.array(level1)
>>> a
array([[1, 1, 1, 1, 1, 1],
       [1, 0, 0, 0, 0, 1],
       [1, 0, 0, 0, 0, 1],
       [1, 0, 0, 0, 0, 1],
       [1, 0, 0, 0, 0, 1],
       [1, 1, 1, 1, 1, 1]])

For manipulating:

if clicked[0] == 1:
    x = (mousey + cameraY) // 60 # For readability
    y = (mousex + cameraX) // 60 # For readability
    a[x][y] = 1

import json
with open('result.json', 'w') as fp:
    json.dump(sample, fp)

This is an easier way to do it.

In the second line of code the file result.json gets created and opened as the variable fp.

In the third line your dict sample gets written into the result.json!

I found a simple way around this in 2005. Here are my steps:

1. Create a string parameter with values ‘Y’ and ‘N’ called ‘PageBreaks’.
2. Add a group level above the group (value) which was used to split the data to the multiple sheets in Excel.
3. Inserted into the first textbox field for this group, the expression for the ‘PageBreaks’ as such… =IIF(Parameters!PageBreaks.Value="Y",Fields!DISP_PROJECT.Value,"") Note: If the parameter =’Y’ then you will get the multiple sheets for each different value. Otherwise the field is NULL for every group record (which causes only one page break at the end).
4. Change the visibility hidden value of the new grouping row to ‘True’.
5. NOTE: When you do this it will also determine whether or not you have a page break in the view, but my users love it since they have the control.

Thanks for the instructive posts. I'd just like to keep a note that if you're getting "TypeError: foodo() got multiple values for keyword argument 'thing'", it may also be that you're mistakenly passing the 'self' as a parameter when calling the function (probably because you copied the line from the class declaration - it's a common error when one's in a hurry).

SELECT * FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_SCHEMA='SCHEMA_NAME' AND COLUMN_KEY='PRI'; WHERE COLUMN_KEY='PRI';

Use jquery starts with attribute selector

$('[id^=editDialog]')

Alternative solution - 1 (highly recommended)

A cleaner solution is to add a common class to each of the divs & use

$('.commonClass').

But you can use the first one if html markup is not in your hands & cannot change it for some reason.

Alternative solution - 2 (not recommended if n is a large number) (as per @Mihai Stancu's suggestion)

$('#editDialog-0, #editDialog-1, #editDialog-2,...,#editDialog-n')

Note: If there are 2 or 3 selectors and if the list doesn't change, this is probably a viable solution but it is not extensible because we have to update the selectors when there is a new ID in town.

File extensions do not have any bearing or impact on the content of the file. You can hold YAML content in files with any extension: .yml, .yaml or indeed anything else.

The (rather sparse) YAML FAQ recommends that you use .yaml in preference to .yml, but for historic reasons many Windows programmers are still scared of using extensions with more than three characters and so opt to use .yml instead.

So, what really matters is what is inside the file, rather than what its extension is.

INSERTED and DELETED are virtual tables. They need to be used in a FROM clause.

CREATE TRIGGER sampleTrigger
    ON database1.dbo.table1
    FOR DELETE
AS
    IF EXISTS (SELECT foo
               FROM database2.dbo.table2
               WHERE id IN (SELECT deleted.id FROM deleted)
               AND bar = 4)

Here is a simple function

public static String capEachWord(String source){
    String result = "";
    String[] splitString = source.split(" ");
    for(String target : splitString){
        result += Character.toUpperCase(target.charAt(0))
                + target.substring(1) + " ";
    }
    return result.trim();
}

I'm not suggested this as the best answer, just an alternative but you can also do something like:

flag = reader[0] == "True"

flag will be True id reader[0] is "True", otherwise it will be False.

There are new features added. But, you will have to see if it is worth the upgrade. Some good improvements in Management Studio 2008 though, especially the intellisense for the Query Editor.

Here is a visual presentation of the approved answer.

Try to have the function body before the function call in your JavaScript file.

A condensed code block is as follows:

   new Handler(Looper.getMainLooper()).post(new Runnable() {
       @Override
       public void run() {
           // things to do on the main thread
       }
   });

This does not involve passing down the Activity reference or the Application reference.

Kotlin Equivalent:

    Handler(Looper.getMainLooper()).post(Runnable {
        // things to do on the main thread
    })

As other answers explain Memory in Java is divided into two portions

1. Stack: One stack is created per thread and it stores stack frames which again stores local variables and if a variable is a reference type then that variable refers to a memory location in heap for the actual object.

2. Heap: All kinds of objects will be created in heap only.

Heap memory is again divided into 3 portions

1. Young Generation: Stores objects which have a short life, Young Generation itself can be divided into two categories Eden Space and Survivor Space.

2. Old Generation: Store objects which have survived many garbage collection cycles and still being referenced.

3. Permanent Generation: Stores metadata about the program e.g. runtime constant pool.

String constant pool belongs to the permanent generation area of Heap memory.

We can see the runtime constant pool for our code in the bytecode by using javap -verbose class_name which will show us method references (#Methodref), Class objects ( #Class ), string literals ( #String )

You can read more about it on my article How Does JVM Handle Method Overloading and Overriding Internally.

• 1) Don't use gets! You're introducing a buffer-overflow vulnerability. Use fgets(..., stdin) instead.

• 2) In strToLower you're returning a char instead of a char-array. Either return char* as Autopulated suggested, or just return void since you're modifying the input anyway. As a result, just write

 strToLower(cString1);
 strToLower(cString2);

• 3) To compare case-insensitive strings, you can use strcasecmp (Linux & Mac) or stricmp (Windows).

I thought my Git windows screen was struck but actually a sign in prompt comes behind it.Check for it and enter your credentials and that's it.

What about switch case instead of if-else

  render() {
    switch (this.state.route) {
      case 'loginRoute':
        return (
            <Login changeRoute={this.changeRoute}
              changeName={this.changeName}
              changeRole={this.changeRole} />
        );
      case 'adminRoute':
        return (
            <DashboardAdmin
              role={this.state.role}
              name={this.state.name}
              changeRoute={this.changeRoute}
            />
        );
      default: 
        return <></>;
    }

You can use jsoup or wffweb (HTML5) based.

Sample code for jsoup:-

Document doc = Jsoup.parse("<html></html>");
doc.body().addClass("body-styles-cls");
doc.body().appendElement("div");
System.out.println(doc.toString());

prints

<html>
 <head></head>
 <body class=" body-styles-cls">
  <div></div>
 </body>
</html>

Sample code for wffweb:-

Html html = new Html(null) {{
    new Head(this);
    new Body(this,
        new ClassAttribute("body-styles-cls"));
}};

Body body = TagRepository.findOneTagAssignableToTag(Body.class, html);
body.appendChild(new Div(null));

System.out.println(html.toHtmlString());
//directly writes to file
html.toOutputStream(new FileOutputStream("/home/user/filepath/filename.html"), "UTF-8");

prints (in minified format):-

<html>
<head></head>
<body class="body-styles-cls">
    <div></div>
</body>
</html>

Here is some code that will manage your MongoDB connections.

var MongoClient = require('mongodb').MongoClient;
var url = require("../config.json")["MongoDBURL"]

var option = {
  db:{
    numberOfRetries : 5
  },
  server: {
    auto_reconnect: true,
    poolSize : 40,
    socketOptions: {
        connectTimeoutMS: 500
    }
  },
  replSet: {},
  mongos: {}
};

function MongoPool(){}

var p_db;

function initPool(cb){
  MongoClient.connect(url, option, function(err, db) {
    if (err) throw err;

    p_db = db;
    if(cb && typeof(cb) == 'function')
        cb(p_db);
  });
  return MongoPool;
}

MongoPool.initPool = initPool;

function getInstance(cb){
  if(!p_db){
    initPool(cb)
  }
  else{
    if(cb && typeof(cb) == 'function')
      cb(p_db);
  }
}
MongoPool.getInstance = getInstance;

module.exports = MongoPool;

When you start the server, call initPool

require("mongo-pool").initPool();

Then in any other module you can do the following:

var MongoPool = require("mongo-pool");
MongoPool.getInstance(function (db){
    // Query your MongoDB database.
});

This is based on MongoDB documentation. Take a look at it.

IEnumerable is refering to a collection but IQueryable is just a query and it will be generated inside a Expression Tree.we will run this query to get data from database.

You can do it without root permissions:

cat srcfile > /mnt/sdcard/dstfile

I love the approach to set the following in file ~/.ssh/config:

# Configuration for GitHub to support multiple GitHub  keys
Host  github.com
  HostName github.com
  User git

# UseKeychain adds each keys passphrase to the keychain so you
# don't have to enter the passphrase each time.
  UseKeychain yes

# AddKeysToAgent would add the key to the agent whenever it is
# used, which might lead to debugging confusion since then
# sometimes the one repository works and sometimes the
# other depending on which key is used first.
#  AddKeysToAgent yes

# I only use my private id file so all private
# repositories don't need the environment variable
# `GIT_SSH_COMMAND="ssh -i ~/.ssh/id_rsa"` to be set.
  IdentityFile ~/.ssh/id_rsa

Then in your repository you can create a .env file which contains the ssh command to be used:

GIT_SSH_COMMAND="ssh -i ~/.ssh/your_ssh_key"

If you then use e.g. dotenv the environment environment variable is exported automatically and whoop whoop, you can specify the key you want per project/directory. The passphrase is asked for only once since it is added to the keychain.

This solution works perfectly with Git and is designed to work on a Mac (due to UseKeychain).

The easiest way is to turn the int into a string and take each character of the string as an element of your list:

>>> n = 43365644 
>>> digits = [int(x) for x in str(n)]
>>> digits
[4, 3, 3, 6, 5, 6, 4, 4]
>>> lst.extend(digits)  # use the extends method if you want to add the list to another

It involves a casting operation, but it's readable and acceptable if you don't need extreme performance.

If you are using updatepanel on onclick event, this may happen.

Use 'EnableEventValidation="false"' in your page markup like this :

<%@ Page Language="C#" MasterPageFile="~/ars_home.master" AutoEventWireup="true" CodeFile="Transaction_Window.aspx.cs" Inherits="Transaction_Window" EnableEventValidation="false" %>

A . in regex is a metacharacter, it is used to match any character. To match a literal dot, you need to escape it, so \.

There is not. You will need to use some external library, or write your own parser. If you have the time to do so, I suggest to write your own parser as it is a quite interesting project. Otherwise you will need to use something like bcParser.

What about this?

git stash apply stash^{/stashname}

Based on the Laravel docs, since version 6.x Input has been removed.

The Input Facade

Likelihood Of Impact: Medium

The Input facade, which was primarily a duplicate of the Request facade, has been removed. If you are using the Input::get method, you should now call the Request::input method. All other calls to the Input facade may simply be updated to use the Request facade.

The data given on their site shows performance of 2x - 4x over protobuf, I have not tried this myself, but if you are evaluating various options, try this as well

See:

.append() puts data inside an element at last index and
.prepend() puts the prepending elem at first index

suppose:

<div class='a'> //<---you want div c to append in this
  <div class='b'>b</div>
</div>

when .append() executes it will look like this:

$('.a').append($('.c'));

after execution:

<div class='a'> //<---you want div c to append in this
  <div class='b'>b</div>
  <div class='c'>c</div>
</div>

Fiddle with .append() in execution.

when .prepend() executes it will look like this:

$('.a').prepend($('.c'));

after execution:

<div class='a'> //<---you want div c to append in this
  <div class='c'>c</div>
  <div class='b'>b</div>
</div>

Fiddle with .prepend() in execution.

.after() puts the element after the element
.before() puts the element before the element

using after:

$('.a').after($('.c'));

after execution:

<div class='a'>
  <div class='b'>b</div>
</div>
<div class='c'>c</div> //<----this will be placed here

Fiddle with .after() in execution.

using before:

$('.a').before($('.c'));

after execution:

<div class='c'>c</div> //<----this will be placed here
<div class='a'>
  <div class='b'>b</div>
</div>

Fiddle with .before() in execution.

I'm aware he's not asking for the inline version. But since this question has almost 100k visits and I fell here looking for that, I'll leave it here for the next fellow coder:

Make sure ESLint is not run with the --no-inline-config flag (if this doesn't sound familiar, you're likely good to go). Then, write this in your code file (for clarity and convention, it's written on top of the file but it'll work anywhere):

/* eslint-env browser */

This tells ESLint that your working environment is a browser, so now it knows what things are available in a browser and adapts accordingly.

There are plenty of environments, and you can declare more than one at the same time, for example, in-line:

/* eslint-env browser, node */

If you are almost always using particular environments, it's best to set it in your ESLint's config file and forget about it.

From their docs:

An environment defines global variables that are predefined. The available environments are:

• browser - browser global variables.
• node - Node.js global variables and Node.js scoping.
• commonjs - CommonJS global variables and CommonJS scoping (use this for browser-only code that uses Browserify/WebPack).
• shared-node-browser - Globals common to both Node and Browser.

[...]

Besides environments, you can make it ignore anything you want. If it warns you about using console.log() but you don't want to be warned about it, just inline:

/* eslint-disable no-console */

You can see the list of all rules, including recommended rules to have for best coding practices.

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.

Cursors make people overly apply a procedural mindset to a set-based environment.

And they are SLOW!!!

From SQLTeam:

Please note that cursors are the SLOWEST way to access data inside SQL Server. The should only be used when you truly need to access one row at a time. The only reason I can think of for that is to call a stored procedure on each row. In the Cursor Performance article I discovered that cursors are over thirty times slower than set based alternatives.

I know this is old, but now Underscore has a new map for objects :

_.mapObject(object, iteratee, [context]) 

You can of course build a flexible map for both arrays and objects

_.fmap = function(arrayOrObject, fn, context){
    if(this.isArray(arrayOrObject))
      return _.map(arrayOrObject, fn, context);
    else
      return _.mapObject(arrayOrObject, fn, context);
}

There is really no way of "one-lining" what you are trying to do because toArray returns an Object[] and you cannot cast from Object[] to int[] or Integer[] to int[]

New version, now you also have the GC= try to replace both DPB and GC with those

DPB="DBD9775A4B774B77B4894C77DFE8FE6D2CCEB951E8045C2AB7CA507D8F3AC7E3A7F59012A2" GC="BAB816BBF4BCF4BCF4"

password will be "test"

I found the easiest way to check if installed was to:

• run a command prompt (Start, Run, cmd, then OK)
• type powershell then hit return. You should then get the PowerShell PS prompt:

C:\Users\MyUser>powershell

Windows PowerShell
Copyright (C) 2009 Microsoft Corporation. All rights reserved.

PS C:\Users\MyUser>

You can then check the version from the PowerShell prompt by typing $PSVersionTable.PSVersion:

PS C:\Users\MyUser> $PSVersionTable.PSVersion

Major  Minor  Build  Revision
-----  -----  -----  --------
2      0      -1     -1

PS C:\Users\MyUser>

Type exit if you want to go back to the command prompt (exit again if you want to also close the command prompt).

To run scripts, see http://ss64.com/ps/syntax-run.html.

You can use the sys.dm_tran_locks view, which returns information about the currently active lock manager resources.

Try this

 SELECT 
     SessionID = s.Session_id,
     resource_type,   
     DatabaseName = DB_NAME(resource_database_id),
     request_mode,
     request_type,
     login_time,
     host_name,
     program_name,
     client_interface_name,
     login_name,
     nt_domain,
     nt_user_name,
     s.status,
     last_request_start_time,
     last_request_end_time,
     s.logical_reads,
     s.reads,
     request_status,
     request_owner_type,
     objectid,
     dbid,
     a.number,
     a.encrypted ,
     a.blocking_session_id,
     a.text       
 FROM   
     sys.dm_tran_locks l
     JOIN sys.dm_exec_sessions s ON l.request_session_id = s.session_id
     LEFT JOIN   
     (
         SELECT  *
         FROM    sys.dm_exec_requests r
         CROSS APPLY sys.dm_exec_sql_text(sql_handle)
     ) a ON s.session_id = a.session_id
 WHERE  
     s.session_id > 50

foo(*ob);

You don't need to cast it because it's the same Object type, you just need to dereference it.

Try:

name = "^aH^ai"
name = name:gsub("%^a", "")

Apparently you can use this trick.

<title> My title</title>

That icon-alike is actually a text.

For your iphone You could use in your head balise :

"width=device-width"

This works for me:

1. I deleted all tables in my database, mainly the migrations table.
2. php artisan migrate:refresh

in laravel 5.5.43

I had the same problem with a Google Docs URL. Enclosing the URL in quotes did the trick for me:

wget "https://docs.google.com/spreadsheets/export?format=tsv&id=1sSi9f6m-zKteoXA4r4Yq-zfdmL4rjlZRt38mejpdhC23" -O sheet.tsv

Get the byte array (byte[]) representation of the image, then use Convert.ToBase64String(), st. like this:

byte[] imageArray = System.IO.File.ReadAllBytes(@"image file path");
string base64ImageRepresentation = Convert.ToBase64String(imageArray);

To convert a base64 image back to a System.Drawing.Image:

var img = Image.FromStream(new MemoryStream(Convert.FromBase64String(base64String)));

Try writting the lambda with the same conditions as the delegate. like this:

  List<AnalysisObject> analysisObjects = 
    analysisObjectRepository.FindAll().Where(
    (x => 
       (x.ID == packageId)
    || (x.Parent != null && x.Parent.ID == packageId)
    || (x.Parent != null && x.Parent.Parent != null && x.Parent.Parent.ID == packageId)
    ).ToList();

As far as I know, you can't.

Besides, that isnt what CSS is for anyway. CSS is for styling and HTML is for markup.

Use this:

static int RandomNumber(int min, int max)
{
    Random random = new Random(); return random.Next(min, max);

}

This is example for you to modify and use in your application.

You don't need to use display:inline to achieve this:

.inline { 
    border: 1px solid red;
    margin:10px;
    float:left;/*Add float left*/
    margin :10px;
}

You can use float-left.

Using float:left is best way to place multiple div elements in one line. Why? Because inline-block does have some problem when is viewed in IE older versions.

fiddle

I think, it should be like this:

    class foo():
        input = get_input(__qualname__)

You can use the following method to keep alphanumeric characters.

replaceAll("[^a-zA-Z0-9]", "");

And if you want to keep only alphabetical characters use this

replaceAll("[^a-zA-Z]", "");

Underscore.js provides a function for this:

_.escape(string)

Escapes a string for insertion into HTML, replacing &, <, >, ", and ' characters.

http://underscorejs.org/#escape

It's not a built-in Javascript function, but if you are already using Underscore it is a better alternative than writing your own function if your strings to convert are not too large.

Valid timeZone values are based on the tz (timezone) database used by Linux and other Unix systems. The values are strings (xsd:string) in the form “Area/Location,” in which:

Area is a continent or ocean name. Area currently includes:

• Africa
• America (both North America and South America)
• Antarctica
• Arctic
• Asia
• Atlantic
• Australia
• Europe
• Etc (administrative zone. For example, “Etc/UTC” represents Coordinated Universal Time.)
• Indian
• Pacific

Location is the city, island, or other regional name.

The zone names and output abbreviations adhere to POSIX (portable operating system interface) UNIX conventions, which uses positive (+) signs west of Greenwich and negative (-) signs east of Greenwich, which is the opposite of what is generally expected. For example, “Etc/GMT+4” corresponds to 4 hours behind UTC (that is, west of Greenwich) rather than 4 hours ahead of UTC (Coordinated Universal Time) (east of Greenwich).

Here is a list all valid timezones

You can change time zone in your settings.py as follows

LANGUAGE_CODE = 'en-us'

TIME_ZONE = 'Asia/Kolkata'

USE_I18N = True

USE_L10N = True

USE_TZ = True

UPDATE:

onActivityCreated() is deprecated from API Level 28.

onCreate():

The onCreate() method in a Fragment is called after the Activity's onAttachFragment() but before that Fragment's onCreateView().
In this method, you can assign variables, get Intent extras, and anything else that doesn't involve the View hierarchy (i.e. non-graphical initialisations). This is because this method can be called when the Activity's onCreate() is not finished, and so trying to access the View hierarchy here may result in a crash.

onCreateView():

After the onCreate() is called (in the Fragment), the Fragment's onCreateView() is called. You can assign your View variables and do any graphical initialisations. You are expected to return a View from this method, and this is the main UI view, but if your Fragment does not use any layouts or graphics, you can return null (happens by default if you don't override).

onActivityCreated():

As the name states, this is called after the Activity's onCreate() has completed. It is called after onCreateView(), and is mainly used for final initialisations (for example, modifying UI elements). This is deprecated from API level 28.

To sum up...
... they are all called in the Fragment but are called at different times.
The onCreate() is called first, for doing any non-graphical initialisations. Next, you can assign and declare any View variables you want to use in onCreateView(). Afterwards, use onActivityCreated() to do any final initialisations you want to do once everything has completed.

If you want to view the official Android documentation, it can be found here:

• onCreate()
• onCreateView()
• onActivityCreated()_

There are also some slightly different, but less developed questions/answers here on Stack Overflow:

• onCreate() vs onCreateView()
• onCreateView() vs onActivityCreated()

I assume you are using windows. Open the command prompt and type ipconfig and find out your local address (on your pc) it should look something like 192.168.1.13 or 192.168.0.5 where the end digit is the one that changes. It should be next to IPv4 Address.

If your WAMP does not use virtual hosts the next step is to enter that IP address on your phones browser ie http://192.168.1.13 If you have a virtual host then you will need root to edit the hosts file.

If you want to test the responsiveness / mobile design of your website you can change your user agent in chrome or other browsers to mimic a mobile.

See http://googlesystem.blogspot.co.uk/2011/12/changing-user-agent-new-google-chrome.html.

Edit: Chrome dev tools now has a mobile debug tool where you can change the size of the viewport, spoof user agents, connections (4G, 3G etc).

If you get forbidden access then see this question WAMP error: Forbidden You don't have permission to access /phpmyadmin/ on this server. Basically, change the occurrances of deny,allow to allow,deny in the httpd.conf file. You can access this by the WAMP menu.

To eliminate possible causes of the issue for now set your config file to

<Directory />
    Options FollowSymLinks
    AllowOverride All
    Order allow,deny
    Allow from all
    <RequireAll>
        Require all granted
    </RequireAll>
</Directory>

As thatis working for my windows PC, if you have the directory config block as well change that also to allow all.

Config file that fixed the problem:

https://gist.github.com/samvaughton/6790739

Problem was that the /www apache directory config block still had deny set as default and only allowed from localhost.

To remove everything before a specific char, use below.

string1 = string1.Substring(string1.IndexOf('$') + 1);

What this does is, takes everything before the $ char and removes it. Now if you want to remove the items after a character, just change the +1 to a -1 and you are set!

But for a URL, I would use the built in .NET class to take of that.

ul>li selects all li that are a direct child of ul whereas ul li selects all li that are anywhere within (descending as deep as you like) a ul

For HTML:

<ul>
  <li><span><a href='#'>Something</a></span></li>
  <li><a href='#'>or Other</a></li>
</ul>

And CSS:

li a{ color: green; }
li>a{ color: red; }

The colour of Something will remain green but or Other will be red

Part 2, you should write the rule to be appropriate to the situation, I think the speed difference would be incredibly small, and probably overshadowed by the extra characters involved in writing more code, and definitely overshadowed by the time taken by the developer to think about it.

However, as a rule of thumb, the more specific you are with your rules, the faster the CSS engines can locate the DOM elements you want to apply it to, so I expect li>a is faster than li a as the DOM search can be cut short earlier. It also means that nested anchors are not styled with that rule, is that what you want? <~~ much more pertinent question.

This is my personal understanding about the topic.

For a project, we can do the version control by different repositories. And for a repository, it can manage a whole project or part of projects.

Regarding on your project (several prototype applications which are independent of each them). You can manage the project by one repository or by several repositories, the difference:

1. Manage by one repository. If one of the applications is changed, the whole project (all the applications) will be committed to a new version.

2. Manage by several repositories. If one application is changed, it will only affect the repository which manages the application. Version for other repositories was not changed.

%s is for string %d is for decimal (or int) %c is for character

It appears to be chewing through an array of characters, and printing out whatever string exists starting at each subsequent position. The strings will stop at the first null in each case.

The commas are just separating the arguments to a function that takes a variable number of args; this number corresponds to the number of % args in the format descriptor at the front.

I have similar situation, I wanted to test if the user is in a certain group. So, I've created new file utils.py where I put all my small utilities that help me through entire application. There, I've have this definition:

utils.py

def is_company_admin(user):
    return user.groups.filter(name='company_admin').exists()

so basically I am testing if the user is in the group company_admin and for clarity I've called this function is_company_admin.

When I want to check if the user is in the company_admin I just do this:

views.py

from .utils import *

if is_company_admin(request.user):
        data = Company.objects.all().filter(id=request.user.company.id)

Now, if you wish to test same in your template, you can add is_user_admin in your context, something like this:

views.py

return render(request, 'admin/users.html', {'data': data, 'is_company_admin': is_company_admin(request.user)})

Now you can evaluate you response in a template:

users.html

{% if is_company_admin %}
     ... do something ...
{% endif %}

Simple and clean solution, based on answers that can be found earlier in this thread, but done differently. Hope it will help someone.

Tested in Django 3.0.4.

This is the version I wrote. Combines several of the other solutions into one.

def to_bool(value):
    """
    Converts 'something' to boolean. Raises exception if it gets a string it doesn't handle.
    Case is ignored for strings. These string values are handled:
      True: 'True', "1", "TRue", "yes", "y", "t"
      False: "", "0", "faLse", "no", "n", "f"
    Non-string values are passed to bool.
    """
    if type(value) == type(''):
        if value.lower() in ("yes", "y", "true",  "t", "1"):
            return True
        if value.lower() in ("no",  "n", "false", "f", "0", ""):
            return False
        raise Exception('Invalid value for boolean conversion: ' + value)
    return bool(value)

If it gets a string it expects specific values, otherwise raises an Exception. If it doesn't get a string, just lets the bool constructor figure it out. Tested these cases:

test_cases = [
    ('true', True),
    ('t', True),
    ('yes', True),
    ('y', True),
    ('1', True),
    ('false', False),
    ('f', False),
    ('no', False),
    ('n', False),
    ('0', False),
    ('', False),
    (1, True),
    (0, False),
    (1.0, True),
    (0.0, False),
    ([], False),
    ({}, False),
    ((), False),
    ([1], True),
    ({1:2}, True),
    ((1,), True),
    (None, False),
    (object(), True),
    ]

Why is gets() dangerous

The first internet worm (the Morris Internet Worm) escaped about 30 years ago (1988-11-02), and it used gets() and a buffer overflow as one of its methods of propagating from system to system. The basic problem is that the function doesn't know how big the buffer is, so it continues reading until it finds a newline or encounters EOF, and may overflow the bounds of the buffer it was given.

You should forget you ever heard that gets() existed.

The C11 standard ISO/IEC 9899:2011 eliminated gets() as a standard function, which is A Good Thing™ (it was formally marked as 'obsolescent' and 'deprecated' in ISO/IEC 9899:1999/Cor.3:2007 — Technical Corrigendum 3 for C99, and then removed in C11). Sadly, it will remain in libraries for many years (meaning 'decades') for reasons of backwards compatibility. If it were up to me, the implementation of gets() would become:

char *gets(char *buffer)
{
    assert(buffer != 0);
    abort();
    return 0;
}

Given that your code will crash anyway, sooner or later, it is better to head the trouble off sooner rather than later. I'd be prepared to add an error message:

fputs("obsolete and dangerous function gets() called\n", stderr);

Modern versions of the Linux compilation system generates warnings if you link gets() — and also for some other functions that also have security problems (mktemp(), …).

Alternatives to gets()

fgets()

As everyone else said, the canonical alternative to gets() is fgets() specifying stdin as the file stream.

char buffer[BUFSIZ];

while (fgets(buffer, sizeof(buffer), stdin) != 0)
{
    ...process line of data...
}

What no-one else yet mentioned is that gets() does not include the newline but fgets() does. So, you might need to use a wrapper around fgets() that deletes the newline:

char *fgets_wrapper(char *buffer, size_t buflen, FILE *fp)
{
    if (fgets(buffer, buflen, fp) != 0)
    {
        size_t len = strlen(buffer);
        if (len > 0 && buffer[len-1] == '\n')
            buffer[len-1] = '\0';
        return buffer;
    }
    return 0;
}

Or, better:

char *fgets_wrapper(char *buffer, size_t buflen, FILE *fp)
{
    if (fgets(buffer, buflen, fp) != 0)
    {
        buffer[strcspn(buffer, "\n")] = '\0';
        return buffer;
    }
    return 0;
}

Also, as caf points out in a comment and paxdiablo shows in his answer, with fgets() you might have data left over on a line. My wrapper code leaves that data to be read next time; you can readily modify it to gobble the rest of the line of data if you prefer:

        if (len > 0 && buffer[len-1] == '\n')
            buffer[len-1] = '\0';
        else
        {
             int ch;
             while ((ch = getc(fp)) != EOF && ch != '\n')
                 ;
        }

The residual problem is how to report the three different result states — EOF or error, line read and not truncated, and partial line read but data was truncated.

This problem doesn't arise with gets() because it doesn't know where your buffer ends and merrily tramples beyond the end, wreaking havoc on your beautifully tended memory layout, often messing up the return stack (a Stack Overflow) if the buffer is allocated on the stack, or trampling over the control information if the buffer is dynamically allocated, or copying data over other precious global (or module) variables if the buffer is statically allocated. None of these is a good idea — they epitomize the phrase 'undefined behaviour`.

There is also the TR 24731-1 (Technical Report from the C Standard Committee) which provides safer alternatives to a variety of functions, including gets():

§6.5.4.1 The gets_s function

Synopsis

#define __STDC_WANT_LIB_EXT1__ 1
#include <stdio.h>
char *gets_s(char *s, rsize_t n);

Runtime-constraints

s shall not be a null pointer. n shall neither be equal to zero nor be greater than RSIZE_MAX. A new-line character, end-of-file, or read error shall occur within reading n-1 characters from stdin.²⁵⁾

3 If there is a runtime-constraint violation, s[0] is set to the null character, and characters are read and discarded from stdin until a new-line character is read, or end-of-file or a read error occurs.

Description

4 The gets_s function reads at most one less than the number of characters specified by n from the stream pointed to by stdin, into the array pointed to by s. No additional characters are read after a new-line character (which is discarded) or after end-of-file. The discarded new-line character does not count towards number of characters read. A null character is written immediately after the last character read into the array.

5 If end-of-file is encountered and no characters have been read into the array, or if a read error occurs during the operation, then s[0] is set to the null character, and the other elements of s take unspecified values.

Recommended practice

6 The fgets function allows properly-written programs to safely process input lines too long to store in the result array. In general this requires that callers of fgets pay attention to the presence or absence of a new-line character in the result array. Consider using fgets (along with any needed processing based on new-line characters) instead of gets_s.

²⁵⁾ The gets_s function, unlike gets, makes it a runtime-constraint violation for a line of input to overflow the buffer to store it. Unlike fgets, gets_s maintains a one-to-one relationship between input lines and successful calls to gets_s. Programs that use gets expect such a relationship.

The Microsoft Visual Studio compilers implement an approximation to the TR 24731-1 standard, but there are differences between the signatures implemented by Microsoft and those in the TR.

The C11 standard, ISO/IEC 9899-2011, includes TR24731 in Annex K as an optional part of the library. Unfortunately, it is seldom implemented on Unix-like systems.

getline() — POSIX

POSIX 2008 also provides a safe alternative to gets() called getline(). It allocates space for the line dynamically, so you end up needing to free it. It removes the limitation on line length, therefore. It also returns the length of the data that was read, or -1 (and not EOF!), which means that null bytes in the input can be handled reliably. There is also a 'choose your own single-character delimiter' variation called getdelim(); this can be useful if you are dealing with the output from find -print0 where the ends of the file names are marked with an ASCII NUL '\0' character, for example.

I managed to fix this by adding:

android:layout_marginTop="?android:attr/actionBarSize"

to the FrameLayout like so:

 <FrameLayout
        android:id="@+id/content"
        android:layout_marginTop="?android:attr/actionBarSize"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
       />

bool_series=pd.notnull(dat["x"])
dat=dat[bool_series]

I solved because I have the same problem and I give you some clues:

1.- As @eggyal comments

mydatabase != mydatabasename

So, check your database name

2.- if in your file, you want create database, you can't set database that you not create yet:

mysql -uroot -pmypassword mydatabase<mydatabase.sql;

change it for:

mysql -uroot -pmypassword <mydatabase.sql;

 String filePath="/storage/emulated/0/DCIM"+app_name;
    File dir=new File(filePath);
    if(!dir.exists()){
        dir.mkdir();
    }

This code is in onCreate method.This code is for creating a directory of app_name. Now,this directory can be accessed using default file manager app in android. Use this string filePath wherever required to set your destination folder. I am sure this method works on Android 7 too because I tested on it.Hence,it can work on other versions of android too.

Just Giving an alternative way to create the file only if doesn't exists using Path and Files.

Path path = Paths.get("Some/path/filename.txt");
Files.createDirectories(path.getParent());
if( !Files.exists(path))
    Files.createFile(path);
Files.write(path, ("").getBytes());

Here is a slightly easier method I just came up with when researching this:

git fetch {remote}
git checkout FETCH_HEAD -- {file}

Basically with UNSIGNED, you're giving yourself twice as much space for the integer since you explicitly specify you don't need negative numbers (usually because values you store will never be negative).

it doesn't work that way. the work around is to manually check the coordinates of the mouse click against the area occupied by each element.

area occupied by an element can found found by 1. getting the location of the element with respect to the top left of the page, and 2. the width and the height. a library like jQuery makes this pretty simple, although it can be done in plain js. adding an event handler for mousemove on the document object will provide continuous updates of the mouse position from the top and left of the page. deciding if the mouse is over any given object consists of checking if the mouse position is between the left, right, top and bottom edges of an element.

/*

If your delimiters are slash-based, escape it:

\/*

* means "0 or more of the previous repeatable pattern", which can be a single character, a character class or a group.

When the branch is no remote branch you can push your local branch direct to the remote.

git checkout master
git push origin master

or when you have a dev branch

git checkout dev
git push origin dev

or when the remote branch exists

git branch dev -t origin/dev

There are some other posibilites to push a remote branch.

You could set the width of the abbrev column to a fixed pixel width, then set the width of the description column to the width of the DataGridView, minus the sum of the widths of the other columns and some extra margin (if you want to prevent a horizontal scrollbar from appearing on the DataGridView):

dataGridView1.Columns[1].Width = 108;  // or whatever width works well for abbrev
dataGridView1.Columns[2].Width = 
    dataGridView1.Width 
    - dataGridView1.Columns[0].Width 
    - dataGridView1.Columns[1].Width 
    - 72;  // this is an extra "margin" number of pixels

If you wanted the description column to always take up the "remainder" of the width of the DataGridView, you could put something like the above code in a Resize event handler of the DataGridView.

The simplest way is to simply use the following line of jquery, using this you don't get the /fakepath nonsense, you straight up get the file that was uploaded:

$('input[type=file]')[0].files[0]; // This gets the file
$('#idOfFileUpload')[0].files[0]; // This gets the file with the specified id

Some other useful commands are:

To get the name of the file:

$('input[type=file]')[0].files[0].name; // This gets the file name

To get the type of the file:

If I were to upload a PNG, it would return image/png

$("#imgUpload")[0].files[0].type

To get the size (in bytes) of the file:

$("#imgUpload")[0].files[0].size

Also you don't have to use these commands on('change', you can get the values at any time, for instance you may have a file upload and when the user clicks upload, you simply use the commands I listed.

what version of sonar are you using? There is one option called "sonar.skippedModules=yourmodulename".

This will skip the whole module. So be aware of it.

My take on it:

Object.assign(...) only copies properties and we lose the prototype and methods.

Object.create(...) is not copying properties for me and just creating a prototype.

What worked for me is creating a prototype using Object.create(...) and copying properties to it using Object.assign(...):

So for an object foo, make clone like this:

Object.assign(Object.create(foo), foo)

"toString()" is Very useful method which returns a string representation of an object. The "toString()" method returns a string reperentation an object.It is recommended that all subclasses override this method.

Declaration: java.lang.Object.toString()

Since, you have not mentioned which object you want to convert, so I am just using any object in sample code.

Integer integerObject = 5;
String convertedStringObject = integerObject .toString();
System.out.println(convertedStringObject );

You can find the complete code here. You can test the code here.

You can easily solve that in 2 steps:

1- Reach the child element using querySelector like that: var target = element[0].querySelector('tbody tr:first-child td')

2- Transform it to an angular.element object again by doing: var targetElement = angular.element(target)

You will then have access to all expected methods on the targetElement variable.

Null coalescing operator (??)

This operator has been added in PHP 7.0 for the common case of needing to use a ternary operator in conjunction with isset(). It returns its first operand if it exists and is not NULL; otherwise it returns its second operand.

<?php
// Fetches the value of $_GET['user'] and returns 'nobody'
// if it does not exist.
$username = $_GET['user'] ?? 'nobody';
// This is equivalent to:
$username = isset($_GET['user']) ? $_GET['user'] : 'nobody';

// Coalescing can be chained: this will return the first
// defined value out of $_GET['user'], $_POST['user'], and
// 'nobody'.
$username = $_GET['user'] ?? $_POST['user'] ?? 'nobody';
?>

You use something like

from flask import send_file

@app.route('/get_image')
def get_image():
    if request.args.get('type') == '1':
       filename = 'ok.gif'
    else:
       filename = 'error.gif'
    return send_file(filename, mimetype='image/gif')

to send back ok.gif or error.gif, depending on the type query parameter. See the documentation for the send_file function and the request object for more information.

To do this for a specific target, you can do the following:

target_compile_definitions(my_target PRIVATE FOO=1 BAR=1)

You should do this if you have more than one target that you're building and you don't want them all to use the same flags. Also see the official documentation on target_compile_definitions.

This may be helpful while searching keys present in nested objects and nested arrays. And this is a generic solution to all cases.

import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;

public class MyClass
{
    public static Object finalresult = null;
    public static void main(String args[]) throws JSONException
    {
        System.out.println(myfunction(myjsonstring,key));
    }

    public static Object myfunction(JSONObject x,String y) throws JSONException
    {
        JSONArray keys =  x.names();
        for(int i=0;i<keys.length();i++)
        {
            if(finalresult!=null)
            {
                return finalresult;                     //To kill the recursion
            }

            String current_key = keys.get(i).toString();

            if(current_key.equals(y))
            {
                finalresult=x.get(current_key);
                return finalresult;
            }

            if(x.get(current_key).getClass().getName().equals("org.json.JSONObject"))
            {
                myfunction((JSONObject) x.get(current_key),y);
            }
            else if(x.get(current_key).getClass().getName().equals("org.json.JSONArray"))
            {
                for(int j=0;j<((JSONArray) x.get(current_key)).length();j++)
                {
                    if(((JSONArray) x.get(current_key)).get(j).getClass().getName().equals("org.json.JSONObject"))
                    {
                        myfunction((JSONObject)((JSONArray) x.get(current_key)).get(j),y);
                    }
                }
            }
        }
        return null;
    }
}

Possibilities:

1. "key":"value"
2. "key":{Object}
3. "key":[Array]

Logic :

• I check whether the current key and search key are the same, if so I return the value of that key.
• If it is an object, I send the value recursively to the same function.
• If it is an array, I check whether it contains an object, if so I recursively pass the value to the same function.

From RFC 1738 on which characters are allowed in URLs:

Only alphanumerics, the special characters "$-_.+!*'(),", and reserved characters used for their reserved purposes may be used unencoded within a URL.

The reserved characters are ";", "/", "?", ":", "@", "=" and "&", which means you would need to URL encode them if you wish to use them.

In the command line type service apache2 status then hit enter. The result should say:

Apache2 is running (pid xxxx)

Kirk's answer is right on. As a rule, you're not going to have any luck with type inference when your method signature has fewer types of parameters than it has generic type parameters.

In your particular case, it seems you could possibly move the T type parameter to the class level and then get type inference on your Get method:

class ServiceGate<T>
{
    public IAccess<S, T> Get<S>(S sig) where S : ISignatur<T>
    {
        throw new NotImplementedException();
    }
}

Then the code you posted with the CS0411 error could be rewritten as:

static void Main()
{
    // Notice: a bit more cumbersome to write here...
    ServiceGate<SomeType> service = new ServiceGate<SomeType>();

    // ...but at least you get type inference here.
    IAccess<Signatur, SomeType> access = service.Get(new Signatur());
}

We can also use postgresql-easy. It is built on node-postgres and sqlutil. Note: pg_connection.js & your_handler.js are in the same folder. db.js is in the config folder placed.

pg_connection.js

const PgConnection = require('postgresql-easy');
const dbConfig = require('./config/db');
const pg = new PgConnection(dbConfig);
module.exports = pg;

./config/db.js

module.exports =  {
  database: 'your db',
  host: 'your host',
  port: 'your port',
  user: 'your user',
  password: 'your pwd',
}

your_handler.js

  const pg_conctn = require('./pg_connection');

  pg_conctn.getAll('your table')
    .then(res => {
         doResponseHandlingstuff();
      })
    .catch(e => {
         doErrorHandlingStuff()     
      })

you can use attribute placeholder

<input type="text" name="email" placeholder="[email protected]" size="30" />

or try this for older browsers

<input type="text" name="email" value="[email protected]" size="30" onblur="if(this.value==''){this.value='[email protected]';}" onfocus="if(this.value=='[email protected]'){this.value='';}">

You can use library "fluttertoast". To do this, add it in pubspec.yaml file like:

dependencies:
  fluttertoast: ^3.1.0

Then import that library in the dart file you need the toast and write your code. For example, refer to the following code:

import 'package:flutter/material.dart';
import 'package:fluttertoast/fluttertoast.dart';



class ToastExample extends StatefulWidget {
    @override
    _ToastExampleState createState() {
      return _ToastExampleState();
    }
  }

  class _ToastExampleState extends State {
    void showToast() {
      Fluttertoast.showToast(
          msg: 'Some text',
          toastLength: Toast.LENGTH_SHORT,
          gravity: ToastGravity.CENTER,
          timeInSecForIos: 1,
          backgroundColor: Colors.red,
          textColor: Colors.white
      );
    }

    @override
    Widget build(BuildContext context) {
      return MaterialApp(
        title: 'Toast Tutorial',
        home: Scaffold(
            appBar: AppBar(
              title: Text('Toast Tutorial'),
            ),
            body: Padding(
              padding: EdgeInsets.all(15.0),
              child: Center(
                child: RaisedButton(
                  child: Text('Press to show'),
                  onPressed: showToast,
                ),
              ),
            )
        ),
      );
    }
  }

  void main() => runApp(ToastExample());

Try using:

string ap = c.Request["AP"];

That reads from the cookies, form, query string or server variables.

Alternatively:

string ap = c.Request.Form["AP"];

to just read from the form's data.

This will remove the last field of each line.

Here is an answer according to the MVVM-pattern if you don't want to know about the Window (or any of its event) in the ViewModel.

public interface IClosing
{
    /// <summary>
    /// Executes when window is closing
    /// </summary>
    /// <returns>Whether the windows should be closed by the caller</returns>
    bool OnClosing();
}

In the ViewModel add the interface and implementation

public bool OnClosing()
{
    bool close = true;

    //Ask whether to save changes och cancel etc
    //close = false; //If you want to cancel close

    return close;
}

In the Window I add the Closing event. This code behind doesn't break the MVVM pattern. The View can know about the viewmodel!

void Window_Closing(object sender, System.ComponentModel.CancelEventArgs e)
{
    IClosing context = DataContext as IClosing;
    if (context != null)
    {
        e.Cancel = !context.OnClosing();
    }
}

Data as factor can be used as input to the plot function.

An answer to a similar question has been given here: https://stat.ethz.ch/pipermail/r-help/2010-December/261873.html

Just run the following line in your favorite terminal application:

This answer to a similar question describes how to extend the properties plugin so it can use a remote descriptor for the properties file. The descriptor is basically a jar artifact containing a properties file (the properties file is included under src/main/resources).

The descriptor is added as a dependency to the extended properties plugin so it is on the plugin's classpath. The plugin will search the classpath for the properties file, read the file''s contents into a Properties instance, and apply those properties to the project's configuration so they can be used elsewhere.

You can use this simple code in loop by incrementing count

cv2.imwrite("C:\Sharat\Python\Images\frame%d.jpg" % count, image)

images will be saved in the folder by name line frame0.jpg, frame1.jpg frame2.jpg etc..

function bootstrap_alert() {
        create = function (message, color) {
            $('#alert_placeholder')
                .html('<div class="alert alert-' + color
                    + '" role="alert"><a class="close" data-dismiss="alert">×</a><span>' + message
                    + '</span></div>');
        };
        warning = function (message) {
            create(message, "warning");
        };
        info = function (message) {
            create(message, "info");
        };
        light = function (message) {
            create(message, "light");
        };
        transparent = function (message) {
            create(message, "transparent");
        };
        return {
            warning: warning,
            info: info,
            light: light,
            transparent: transparent
        };
    }

As you mentioned, prompt works for browsers all the way back to IE:

var answer = prompt('question', 'defaultAnswer');

For Node.js > v7.6, you can use console-read-write, which is a wrapper around the low-level readline module:

const io = require('console-read-write');

async function main() {
  // Simple readline scenario
  io.write('I will echo whatever you write!');
  io.write(await io.read());

  // Simple question scenario
  io.write(`hello ${await io.ask('Who are you?')}!`);

  // Since you are not blocking the IO, you can go wild with while loops!
  let saidHi = false;
  while (!saidHi) {
    io.write('Say hi or I will repeat...');
    saidHi = await io.read() === 'hi';
  }

  io.write('Thanks! Now you may leave.');
}

main();
// I will echo whatever you write!
// > ok
// ok
// Who are you? someone
// hello someone!
// Say hi or I will repeat...
// > no
// Say hi or I will repeat...
// > ok
// Say hi or I will repeat...
// > hi
// Thanks! Now you may leave.

Disclosure I'm author and maintainer of console-read-write

For SpiderMonkey, simple readline as suggested by @MooGoo and @Zaz.

read without any parameters will only continue if you press enter. The DOS pause command will continue if you press any key. Use read –n1 if you want this behaviour.

Maybe your class isn't quite complete. Personally, I use a private init() function with all of my overloaded constructors.

class Point2D {

  double X, Y;

  public Point2D(double x, double y) {
    init(x, y);
  }

  public Point2D(Point2D point) {
    if (point == null)
      throw new ArgumentNullException("point");
    init(point.X, point.Y);
  }

  void init(double x, double y) {
    // ... Contracts ...
    X = x;
    Y = y;
  }
}

The function:

function () {}

returns nothing (or undefined).

Sometimes we want to call a function right as we create it. You might be tempted to try this:

function () {}()

but it results in a SyntaxError.

Using the ! operator before the function causes it to be treated as an expression, so we can call it:

!function () {}()

This will also return the boolean opposite of the return value of the function, in this case true, because !undefined is true. If you want the actual return value to be the result of the call, then try doing it this way:

(function () {})()

You might consider using a shell without history, like perhaps

/bin/sh << END
   your commands without history
END

(perhaps /bin/dash or /bin/sash could be more appropriate than /bin/sh)

or even better use the batch utility e.g

batch << EOB
   your commands
EOB

The history would then contain sh or batch which is not very meaningful

You could output them to a .csv file and open the file in excel. Is that direct enough?

1.Update project

Right Click on your project maven > update project

2.Build project

Right Click on your project again. run as > Maven build

If you have not created a “Run configuration” yet, it will open a new configuration with some auto filled values.

You can change the name. "Base directory" will be a auto filled value for you. Keep it as it is. Give maven command to ”Goals” fields.

i.e, “clean install” for building purpose

Click apply

Click run.

3.Run project on tomcat

Right Click on your project again. run as > Run-Configuration. It will open Run-Configuration window for you.

Right Click on “Maven Build” from the right side column and Select “New”. It will open a blank configuration for you.

Change the name as you want. For the base directory field you can choose values using 3 buttons(workspace,FileSystem,Variables). You can also copy and paste the auto generated value from previously created Run-configuration. Give the Goals as “tomcat:run”. Click apply. Click run.

If you want to get more clear idea with snapshots use the following link.

(I hope this answer will help someone come after the topic of the question)

This is an adapter for HashMaps which I implemented for a recent project. Works in a way similart to what @SandyR does, but encapsulates conversion logic so you don't manually convert strings to a wrapper object.

I used Java 8 features but with a few changes, you can adapt it to previous versions. I tested it for most common scenarios, except new Java 8 stream functions.

Basically it wraps a HashMap, directs all functions to it while converting strings to/from a wrapper object. But I had to also adapt KeySet and EntrySet because they forward some functions to the map itself. So I return two new Sets for keys and entries which actually wrap the original keySet() and entrySet().

One note: Java 8 has changed the implementation of putAll method which I could not find an easy way to override. So current implementation may have degraded performance especially if you use putAll() for a large data set.

Please let me know if you find a bug or have suggestions to improve the code.

You can use:

if (myString1.IndexOf("AbC", StringComparison.OrdinalIgnoreCase) >=0) {
    //...
}

This works with any .NET version.

Shaun F's answer will not work if Schema doesn't exist in the DB. If anyone is looking for way to create schema then just execute following script to create schema.

create schema [schema_name]
CREATE TABLE [schema_name].[table_name](
 ...
) ON [PRIMARY]

While adding new table, go to table design mode and press F4 to open property Window and select the schema from dropdown. Default is dbo.

You can also change the schema of the current Table using Property window.

If I understand you correctly, this should do the trick. You'll need add using System.IO at the top of your file if you don't already have it.

        using (var fs = new FileStream(fileName, FileMode.Create, FileAccess.Write))
        {
            fs.Write(byteArray, 0, byteArray.Length);
            return true;
        }
    }
    catch (Exception ex)
    {
        Console.WriteLine("Exception caught in process: {0}", ex);
        return false;
    }
}

You can do the same like this:

@Override
public FaqQuestions getFaqQuestionById(Long questionId) {
    session = sessionFactory.openSession();
    tx = session.beginTransaction();
    FaqQuestions faqQuestions = null;
    try {
        faqQuestions = (FaqQuestions) session.get(FaqQuestions.class,
                questionId);
        Hibernate.initialize(faqQuestions.getFaqAnswers());

        tx.commit();
        faqQuestions.getFaqAnswers().size();
    } finally {
        session.close();
    }
    return faqQuestions;
}

Just use faqQuestions.getFaqAnswers().size()nin your controller and you will get the size if lazily intialised list, without fetching the list itself.

I had to use os.system, since subprocess was giving me a memory error for larger tasks. Reference for this problem here. So, in order to get the output of the os.system command I used this workaround:

import os

batcmd = 'dir'
result_code = os.system(batcmd + ' > output.txt')
if os.path.exists('output.txt'):
    fp = open('output.txt', "r")
    output = fp.read()
    fp.close()
    os.remove('output.txt')
    print(output)

Instead of doing this:

compile "com.android.support:support-v4:18.0.+"

Do this:

compile 'com.android.support:support-v4:18.0.+' 

Worked for me

See project.properties in android project. In ADT 14, default.properties was renamed to project.properties.

Quote from the changelog:

default.properties which is the main project’s properties file containing information such as the build platform target and the library dependencies has been renamed project.properties.

*Note: Per the above link, if you don't have a default.properties file, likely you should upgrade your tools.

See build changes in revision 14, at the bottom under "Project Setup"

You can convert the QString type to python string by just using the str function. Assuming you are not using any Unicode characters you can get a python string as below:

text = str(combobox1.currentText())

If you are using any unicode characters, you can do:

text = unicode(combobox1.currentText())

I want to add my 2 cent experience that might be helpful for many of you.

If you declare a function inside a loop (for, foreach, while), you will face this error message.

Shows the latest file with human readable timestamp:

find . -type f -printf '%TY-%Tm-%Td %TH:%TM: %Tz %p\n'| sort -n | tail -n1

Result looks like this:

2015-10-06 11:30: +0200 ./foo/bar.txt

To show more files, replace -n1 with a higher number

Use the traceback module:

import sys
import traceback

try:
    assert True
    assert 7 == 7
    assert 1 == 2
    # many more statements like this
except AssertionError:
    _, _, tb = sys.exc_info()
    traceback.print_tb(tb) # Fixed format
    tb_info = traceback.extract_tb(tb)
    filename, line, func, text = tb_info[-1]

    print('An error occurred on line {} in statement {}'.format(line, text))
    exit(1)

Add step="0.01" to the <input type="number" /> parameters:

<input type="number" min="0.01" step="0.01" max="2500" value="25.67" />

But the Dollar sign must stay outside the textbox... every non-numeric or separator charachter will be cropped automatically.

Otherwise you could use a classic textbox, like described here.

In the manual for GNU make, they talk about this specific example when describing the value function:

The value function provides a way for you to use the value of a variable without having it expanded. Please note that this does not undo expansions which have already occurred; for example if you create a simply expanded variable its value is expanded during the definition; in that case the value function will return the same result as using the variable directly.

The syntax of the value function is:

 $(value variable)

Note that variable is the name of a variable; not a reference to that variable. Therefore you would not normally use a ‘$’ or parentheses when writing it. (You can, however, use a variable reference in the name if you want the name not to be a constant.)

The result of this function is a string containing the value of variable, without any expansion occurring. For example, in this makefile:

 FOO = $PATH

 all:
         @echo $(FOO)
         @echo $(value FOO)

The first output line would be ATH, since the “$P” would be expanded as a make variable, while the second output line would be the current value of your $PATH environment variable, since the value function avoided the expansion.

You have two options - as @PanPipes answer states you can do the following.

$(element).val(val).trigger('change');

This is an acceptable solution only if one doesn't have any custom actions binded to the change event. The solution I use in this situation is to trigger a select2 specific event which updates the select2 displayed selection.

$(element).val(val).trigger('change.select2');

$db  = new PDO('mysql:host=localhost;dbname=java_db', 'root', 'pass');
$Sql = "SELECT count(*) as `total` FROM users";
$stmt = $db->query($Sql);
$stmt->execute();
$total = $stmt->fetch(PDO::FETCH_ASSOC);
print '<pre>';
print_r($total);
print '</pre>';

Result:

You can use two ways to resolve this problem, first way that i think it as best way is replace importing segment of your code with bellow one:

import Home from './layouts/Home'

or export your component without default which is called named export like this

import React, { Component } from 'react';

class Home extends Component{
    render(){
        return(
        <p className="App-intro">
          Hello Man
        </p>
        )
    }
} 

export {Home};

On any other element, I would use the scrollHeight of the DOM object and set the height accordingly. I don't know if this would work on an iframe (because they're a bit kooky about everything) but it's certainly worth a try.

Edit: Having had a look around, the popular consensus is setting the height from within the iframe using the offsetHeight:

function setHeight() {
    parent.document.getElementById('the-iframe-id').style.height = document['body'].offsetHeight + 'px';
}

And attach that to run with the iframe-body's onLoad event.

This is the btn click event

btnvideo.setOnClickListener(new OnClickListener() {

public void onClick(View v) {

    startActivity(new Intent(Intent.ACTION_VIEW,Uri.parse("http://www.youtube.com/watch?v=Hxy8BZGQ5Jo")));
    Log.i("Video", "Video Playing....");

    }
}); 

this type it opened in another page with the youtube where u can show your video

One pretty important practical difference occurs when subclassing. If you don't mind, I'll hijack @unutbu's example:

class A: 
    def foo(self, x): 
        print("executing foo(%s, %s)" % (self, x)) 
 
    @classmethod
    def class_foo(cls, x): 
        print("executing class_foo(%s, %s)" % (cls, x))
 
    @staticmethod 
    def static_foo(x): 
        print("executing static_foo(%s)" % x)

class B(A):
    pass

In class_foo, the method knows which class it is called on:

A.class_foo(1)
# => executing class_foo(<class '__main__.A'>, 1)
B.class_foo(1)
# => executing class_foo(<class '__main__.B'>, 1)

In static_foo, there is no way to determine whether it is called on A or B:

A.static_foo(1)
# => executing static_foo(1)
B.static_foo(1)
# => executing static_foo(1)

Note that this doesn't mean you can't use other methods in a staticmethod, you just have to reference the class directly, which means subclasses' staticmethods will still reference the parent class:

class A:
    @classmethod
    def class_qux(cls, x):
        print(f"executing class_qux({cls}, {x})")
    
    @classmethod
    def class_bar(cls, x):
        cls.class_qux(x)

    @staticmethod
    def static_bar(x):
        A.class_qux(x)

class B(A):
    pass

A.class_bar(1)
# => executing class_qux(<class '__main__.A'>, 1)
B.class_bar(1)
# => executing class_qux(<class '__main__.B'>, 1)
A.static_bar(1)
# => executing class_qux(<class '__main__.A'>, 1)
B.static_bar(1)
# => executing class_qux(<class '__main__.A'>, 1)

First get the size of screen.

Size size = MediaQuery.of(context).size;

After this you can get width and multiply it with 0.5 to get 50% of screen width.

double width50 = size.width * 0.5;

But problem generally comes in height, by default when we use

double screenHeight = size.height;

The height we get is global height which includes StatusBar + notch + AppBar height. So, in order to get the left height of the device, we need to subtract padding height (StatusBar + notch) and AppBar height from total height. Here is how we do it.

double abovePadding = MediaQuery.of(context).padding.top;
double appBarHeight = appBar.preferredSize.height;
double leftHeight = screenHeight - abovePadding - appBarHeight;

Now we can use following to get 50% of our screen in height.

double height50 = leftHeight * 0.5

For those of you looking for unicode alphanumeric matching, you might want to do something like:

^[\p{L} \p{Nd}_]+$

The easiest option for me was to rename the title of the terminal instead. Please see: https://superuser.com/questions/362227/how-to-change-the-title-of-the-mintty-window

In this answer, they mention to modify the PS1 variable. Note: my situation was particular to cygwin.

TL;DR Put this in your .bashrc file:

function settitle() {
      export PS1="\[\e[32m\]\u@\h \[\e[33m\]\w\[\e[0m\]\n$ "
      echo -ne "\e]0;$1\a"
}

Put this in your .tmux.conf file, or similar formatting:

set -g pane-border-status bottom
set -g pane-border-format "#P #T #{pane_current_command}"

Then you can change the title of the pane by typing this in the console:

settitle titlename
