With the stable release of Android Material Components in Nov 2018, Google has moved the material components from namespace android.support.design to com.google.android.material.
Material Component library is replacement for Android’s Design Support Library.

Add the dependency to your build.gradle:

dependencies { implementation ‘com.google.android.material:material:1.0.0’ }

Then add the MaterialButton to your layout:

<com.google.android.material.button.MaterialButton
        style="@style/Widget.MaterialComponents.Button.OutlinedButton" 
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/app_name"
        app:strokeColor="@color/colorAccent"
        app:strokeWidth="6dp"
        app:layout_constraintStart_toStartOf="parent"
        app:shapeAppearance="@style/MyShapeAppearance"
   />

You can check the full documentation here and API here.

To change the background color you have 2 options.

1. Using the backgroundTint attribute.

Something like:

<style name="MyButtonStyle"
 parent="Widget.MaterialComponents.Button">
    <item name="backgroundTint">@color/button_selector</item>
    //..
</style>

2. It will be the best option in my opinion. If you want to override some theme attributes from a default style then you can use new materialThemeOverlay attribute.

Something like:

<style name="MyButtonStyle"
 parent="Widget.MaterialComponents.Button">
   <item name=“materialThemeOverlay”>@style/GreenButtonThemeOverlay</item>
</style>

<style name="GreenButtonThemeOverlay">
  <!-- For filled buttons, your theme's colorPrimary provides the default background color of the component --> 
  <item name="colorPrimary">@color/green</item>
</style>

The option#2 requires the 'com.google.android.material:material:1.1.0'.

OLD Support Library:

With the new Support Library 28.0.0, the Design Library now contains the MaterialButton.

You can add this button to our layout file with:

<android.support.design.button.MaterialButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="YOUR TEXT"
    android:textSize="18sp"
    app:icon="@drawable/ic_android_white_24dp" />

By default this class will use the accent colour of your theme for the buttons filled background colour along with white for the buttons text colour.

You can customize the button with these attributes:

• app:rippleColor: The colour to be used for the button ripple effect

• app:backgroundTint: Used to apply a tint to the background of the button. If you wish to change the background color of the button, use this attribute instead of background.

• app:strokeColor: The color to be used for the button stroke

• app:strokeWidth: The width to be used for the button stroke
• app:cornerRadius: Used to define the radius used for the corners of the button

<input type="text" style="font-size:xxpt;height:xxpx">

Just replace "xx" with whatever values you wish.

i solved this problem by these steps

1- use FragmentPagerAdapter

2- in each fragment create a random id

fragment.id = new Random().nextInt();

3- override getItemPosition in adapter

@Override
public int getItemPosition(@NonNull Object object) {
    return PagerAdapter.POSITION_NONE;
}

4-override getItemId in adapter

 @Override
public long getItemId(int position) {
    return mDatasetFragments.get(position).id;
}

5- now delete code is

 adapter.mDatasetFragments.remove(< item to delete position >);
 adapter.notifyDataSetChanged();

this worked for me i hope help

this helped me

it will be the launching activity. Click on the module name just to the left of the run button and click on "Edit configurations..." Now make sure "Launch default Activity" is selected.

enum NumberError: Error {
  case NegativeNumber(number: Int)

}

You could use this CMD in your Dockerfile:

CMD exec /bin/bash -c "trap : TERM INT; sleep infinity & wait"

This will keep your container alive until it is told to stop. Using trap and wait will make your container react immediately to a stop request. Without trap/wait stopping will take a few seconds.

For busybox based images (used in alpine based images) sleep does not know about the infinity argument. This workaround gives you the same immediate response to a docker stop like in the above example:

CMD exec /bin/sh -c "trap : TERM INT; sleep 9999999999d & wait"

On Ubuntu 16.04

Here's how I fixed this issue: Refer Docker Compose documentation

1. sudo curl -L https://github.com/docker/compose/releases/download/1.21.0/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose

2. sudo chmod +x /usr/local/bin/docker-compose

After you do the curl command , it'll put docker-compose into the

/usr/local/bin

which is not on the PATH. To fix it, create a symbolic link:

3. sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

And now if you do: docker-compose --version

You'll see that docker-compose is now on the PATH

Another solution could be via pandas Series:

import pandas as pd

a = pd.Series([-2, 1, 5, 3, 8, 5, 6])
b = [1, 2, 5]
c = a[b]

You can then convert c back to a list if you want:

c = list(c)

@Override
public Map<String, String> getHeaders() throws AuthFailureError {
    HashMap<String, String> headers = new HashMap<String, String>();
    headers.put("Content-Type", "application/json; charset=utf-8");
    return headers;
}

You need to add Content-Type to the header.

in my magento2 website ,show exactly the same error when click a product,

my solution is to go to edit the value of Search Engine Optimization - URL Key of this product,

make sure that there are only alphabet,number and - in URL Key, such as 100-washed-cotton-duvet-cover-set, deleting all other special characters ,such as % .

Check internet connection availability in (iOS) using Xcode 9 & Swift 4.0

Follow Below steps

Step 1: Create an extension file and give it the name: ReachabilityManager.swift then add the lines of code below.

import Foundation
import SystemConfiguration
public class ConnectionCheck 
{    
   class func isConnectedToNetwork() -> Bool 
   {
    var zeroAddress = sockaddr_in()
    zeroAddress.sin_len = UInt8(MemoryLayout<sockaddr_in>.size)
    zeroAddress.sin_family = sa_family_t(AF_INET)

    guard let defaultRouteReachability = withUnsafePointer(to: &zeroAddress,         
    {
        $0.withMemoryRebound(to: sockaddr.self, capacity: 1) {
            SCNetworkReachabilityCreateWithAddress(nil, $0)
        }
    }) else {
        return false
    }

    var flags: SCNetworkReachabilityFlags = []
    if !SCNetworkReachabilityGetFlags(defaultRouteReachability, &flags) {
        return false
    }

    let isReachable = flags.contains(.reachable)
    let needsConnection = flags.contains(.connectionRequired)

    return (isReachable && !needsConnection)
   }
  }

Step 2: Call the extension above using the code below.

if ConnectionCheck.isConnectedToNetwork()
{
     print("Connected")
     //Online related Business logic
}
else{
     print("disConnected")
     // offline related business logic
}

Here's a cross browser working function (usable for other than click handlers too):

function eventFire(el, etype){
    if (el.fireEvent) {
      el.fireEvent('on' + etype);
    } else {
      var evObj = document.createEvent('Events');
      evObj.initEvent(etype, true, false);
      el.dispatchEvent(evObj);
    }
}

SwiftUI - Full Example

struct ContentView: View {
    
    @State private var text = defaultText
    
    @State private var isKeyboardShowing = false
    
    private static let defaultText = "write something..."
    
    private var gesture = TapGesture().onEnded({_ in
        UIApplication.shared.endEditing(true)
    })
    
    var body: some View {
        
        ZStack {
            Color.black
            
            VStack(alignment: .leading) {
                TextField("placeholder", text: $text)
                    .foregroundColor(.white)
                    .padding()
                    .background(Color.green)
            }
            
            .padding()
        }
        .edgesIgnoringSafeArea(.all)
        .onChange(of: isKeyboardShowing, perform: { (isShowing) in
            if isShowing {
                if text == Self.defaultText { text = "" }
            } else {
                if text == "" { text = Self.defaultText }
            }
        })
        .simultaneousGesture(gesture)
        .onReceive(NotificationCenter.default
                    .publisher(for: UIResponder.keyboardWillShowNotification), perform: { (value) in
                        isKeyboardShowing = true
                    })
        .onReceive(NotificationCenter.default
                    .publisher(for: UIResponder.keyboardWillHideNotification), perform: { (value) in
                        isKeyboardShowing = false
                    })
    }
}

extension UIApplication {
    func endEditing(_ force: Bool) {
        self.windows
            .filter{$0.isKeyWindow}
            .first?
            .endEditing(force)
    }
}

Using ScalaIDE (3.0.4-2.11-20140723-2253-Typesafe) I was having a similar problem with the Right Click Scala Test Class-> Run As -> Scala Junit Test context menu.

I tried editting the class(but not for a compile failure), cleaning, closing the project, closing Eclipse. None of those worked to restore the context menu for classes that had previously worked well. The test classes don't use the @Test annotation and instead use the @RunWith(classOf[JUnitRunner]) annotation at the top of the class using ScalaTest code.

When I tried choosing Scala Junit Test from the Run Configuration launch editor directly, I received the dialog from the question. Footix29's answer was the key for me.

I noticed that even though I had cleaned my project a few times, my classes in the /bin directory hadn't actually been rebuilt in a while.

Here's how I got back the context menu, and was able to once again run Scala Junit Tests:

• manually cleaned the classes by deleting the /bin/<package dir>* via Explorer
• Project -> Cleaned the project along with a full rebuild

I suspect that a class edit in general is able to clean some saved state of Eclipse and get it going again. In my case all of the previously working classes I tried had failed so the manual clean step was just the hammer I needed. However, other tricks that affect Eclipse's concept of the class path/build state should also work.

Further, I think that this behaviour was triggered in part by attempting to refactor a Scala class by renaming it( which the Scala Eclipse IDE sucks at ), where all the cleanup after the initial file change is manual. There were no build errors, but there were also no warnings that I was expecting meaning something was definitely stuck in Eclipse's build state info.

SQLAlchemy overloads the bitwise operators &, | and ~ so instead of the ugly and hard-to-read prefix syntax with or_() and and_() (like in Bastien's answer) you can use these operators:

.filter((AddressBook.lastname == 'bulger') | (AddressBook.firstname == 'whitey'))

Note that the parentheses are not optional due to the precedence of the bitwise operators.

So your whole query could look like this:

addr = session.query(AddressBook) \
    .filter(AddressBook.city == "boston") \
    .filter((AddressBook.lastname == 'bulger') | (AddressBook.firstname == 'whitey'))

In my case I found this to be an issue with InnoDB; I never discovered what the actual problem was, but creating as a MyISAM allowed it to build

As now in swift 3 / xcode 8 text property is optional you can do it like this:

if ((textField.text ?? "").isEmpty) {
    // is empty
}

or:

if (textField.text?.isEmpty ?? true) {
    // is empty
}

Alternatively you could make an extenstion such as below and use it instead:

extension UITextField {
    var isEmpty: Bool {
        return text?.isEmpty ?? true
    }
}

...

if (textField.isEmpty) {
    // is empty
}

Here is an answer coming right from the libc6! Taking a look at /usr/include/x86_64-linux-gnu/bits/byteswap.h, I found the trick you were looking for.

A few critics of previous solutions:

• Kip's solution does not permit evaluating to an expression, which is in the end often needed.
• coppro's solution does not permit assigning a variable as the expressions are separate, but can evaluate to an expression.
• Steve Jessop's solution uses the C++11 auto keyword, that's fine, but feel free to use the known/expected type instead.

The trick is to use both the (expr,expr) construct and a {} scope:

#define MACRO(X,Y) \
  ( \
    { \
      register int __x = static_cast<int>(X), __y = static_cast<int>(Y); \
      std::cout << "1st arg is:" << __x << std::endl; \
      std::cout << "2nd arg is:" << __y << std::endl; \
      std::cout << "Sum is:" << (__x + __y) << std::endl; \
      __x + __y; \
    } \
  )

Note the use of the register keyword, it's only a hint to the compiler. The X and Y macro parameters are (already) surrounded in parenthesis and casted to an expected type. This solution works properly with pre- and post-increment as parameters are evaluated only once.

For the example purpose, even though not requested, I added the __x + __y; statement, which is the way to make the whole bloc to be evaluated as that precise expression.

It's safer to use void(); if you want to make sure the macro won't evaluate to an expression, thus being illegal where an rvalue is expected.

However, the solution is not ISO C++ compliant as will complain g++ -pedantic:

warning: ISO C++ forbids braced-groups within expressions [-pedantic]

In order to give some rest to g++, use (__extension__ OLD_WHOLE_MACRO_CONTENT_HERE) so that the new definition reads:

#define MACRO(X,Y) \
  (__extension__ ( \
    { \
      register int __x = static_cast<int>(X), __y = static_cast<int>(Y); \
      std::cout << "1st arg is:" << __x << std::endl; \
      std::cout << "2nd arg is:" << __y << std::endl; \
      std::cout << "Sum is:" << (__x + __y) << std::endl; \
      __x + __y; \
    } \
  ))

In order to improve my solution even a bit more, let's use the __typeof__ keyword, as seen in MIN and MAX in C:

#define MACRO(X,Y) \
  (__extension__ ( \
    { \
      __typeof__(X) __x = (X); \
      __typeof__(Y) __y = (Y); \
      std::cout << "1st arg is:" << __x << std::endl; \
      std::cout << "2nd arg is:" << __y << std::endl; \
      std::cout << "Sum is:" << (__x + __y) << std::endl; \
      __x + __y; \
    } \
  ))

Now the compiler will determine the appropriate type. This too is a gcc extension.

Note the removal of the register keyword, as it would the following warning when used with a class type:

warning: address requested for ‘__x’, which is declared ‘register’ [-Wextra]

To find "javaw.exe" in windows I would use (using batch)

for /f tokens^=2^ delims^=^" %%i in ('reg query HKEY_CLASSES_ROOT\jarfile\shell\open\command /ve') do set JAVAW_PATH=%%i

It should work in Windows XP and Seven, for JRE 1.6 and 1.7. Should catch the latest installed version.

Framework 4: no need to use StreamWriter:

I have noticed that no answer display an image with a single legend referencing many curves in different subplots, so I have to show you one... to make you curious...

Now, you want to look at the code, don't you?

from numpy import linspace
import matplotlib.pyplot as plt

# Calling the axes.prop_cycle returns an itertoools.cycle

color_cycle = plt.rcParams['axes.prop_cycle']()

# I need some curves to plot

x = linspace(0, 1, 51)
f1 = x*(1-x)   ; lab1 = 'x - x x'
f2 = 0.25-f1   ; lab2 = '1/4 - x + x x' 
f3 = x*x*(1-x) ; lab3 = 'x x - x x x'
f4 = 0.25-f3   ; lab4 = '1/4 - x x + x x x'

# let's plot our curves (note the use of color cycle, otherwise the curves colors in
# the two subplots will be repeated and a single legend becomes difficult to read)
fig, (a13, a24) = plt.subplots(2)

a13.plot(x, f1, label=lab1, **next(color_cycle))
a13.plot(x, f3, label=lab3, **next(color_cycle))
a24.plot(x, f2, label=lab2, **next(color_cycle))
a24.plot(x, f4, label=lab4, **next(color_cycle))

# so far so good, now the trick

lines_labels = [ax.get_legend_handles_labels() for ax in fig.axes]
lines, labels = [sum(lol, []) for lol in zip(*lines_labels)]

# finally we invoke the legend (that you probably would like to customize...)

fig.legend(lines, labels)
plt.show()

The two lines

lines_labels = [ax.get_legend_handles_labels() for ax in fig.axes]
lines, labels = [sum(lol, []) for lol in zip(*lines_labels)]

deserve an explanation — to this aim I have encapsulated the tricky part in a function, just 4 lines of code but heavily commented

def fig_legend(fig, **kwdargs):

    # generate a sequence of tuples, each contains
    #  - a list of handles (lohand) and
    #  - a list of labels (lolbl)
    tuples_lohand_lolbl = (ax.get_legend_handles_labels() for ax in fig.axes)
    # e.g. a figure with two axes, ax0 with two curves, ax1 with one curve
    # yields:   ([ax0h0, ax0h1], [ax0l0, ax0l1]) and ([ax1h0], [ax1l0])
    
    # legend needs a list of handles and a list of labels, 
    # so our first step is to transpose our data,
    # generating two tuples of lists of homogeneous stuff(tolohs), i.e
    # we yield ([ax0h0, ax0h1], [ax1h0]) and ([ax0l0, ax0l1], [ax1l0])
    tolohs = zip(*tuples_lohand_lolbl)

    # finally we need to concatenate the individual lists in the two
    # lists of lists: [ax0h0, ax0h1, ax1h0] and [ax0l0, ax0l1, ax1l0]
    # a possible solution is to sum the sublists - we use unpacking
    handles, labels = (sum(list_of_lists, []) for list_of_lists in tolohs)

    # call fig.legend with the keyword arguments, return the legend object

    return fig.legend(handles, labels, **kwdargs)

PS I recognize that sum(list_of_lists, []) is a really inefficient method to flatten a list of lists but ? I love its compactness, ? usually is a few curves in a few subplots and ? Matplotlib and efficiency? ;-)

Important Update

If you want to stick with the official Matplotlib API my answer above is perfect, really.

On the other hand, if you don't mind using a private method of the matplotlib.legend module ... it's really much much much easier

from matplotlib.legend import _get_legend_handles_labels
...

fig.legend(*_get_legend_handles_and_labels(fig.axes), ...)

A complete explanation can be found in the source code of Axes.get_legend_handles_labels in .../matplotlib/axes/_axes.py

For the same issues, I have removed the following line,

  File file = new File("c:\\file.xml");
  InputStream inputStream= new FileInputStream(file);
  Reader reader = new InputStreamReader(inputStream,"UTF-8");
  InputSource is = new InputSource(reader);
  is.setEncoding("UTF-8");

It is working fine. Not so sure why that UTF-8 gives problem. To keep me in shock, it works fine for UTF-8 also.

Am using Windows-7 32 bit and Netbeans IDE with Java *jdk1.6.0_13*. No idea how it works.

Identifiers and reserved words should not be case sensitive, although many follow a convention to use capitals for reserved words and Pascal case for identifiers.

See SQL-92 Sec. 5.2

Please find inner join for more than 2 table here

Here are 4 table name like

1. Orders
2. Customers
3. Student
4. Lecturer

So the SQL code would be:

select o.orderid, c.customername, l.lname, s.studadd, s.studmarks 
from orders o 
    inner join customers c on o.customrid = c.customerid 
    inner join lecturer l  on o.customrid = l.id 
    inner join student s   on o.customrid=s.studmarks;

settings.py:

DEBUG = False
TEMPLATE_DEBUG = DEBUG
ALLOWED_HOSTS = ['localhost']  #provide your host name

and just add your 404.html and 500.html pages in templates folder. remove 404.html and 500.html from templates in polls app.

Kind of a confusing group of answers, in part because the title of the question is actually much larger than the specific question being asked. After reading through, I'm not sure any answer is a few edits away from assimilating all the good stuff here, so I figured I'd try to sum.

Here's an extension method that I think avoids the pitfalls mentioned here and provides the most broadly applicable solution.

public static string ReplaceCaseInsensitiveFind(this string str, string findMe,
    string newValue)
{
    return Regex.Replace(str,
        Regex.Escape(findMe),
        Regex.Replace(newValue, "\\$[0-9]+", @"$$$0"),
        RegexOptions.IgnoreCase);
}

So...

• This is an extension method @MarkRobinson
• This doesn't try to skip Regex @Helge (you really have to do byte-by-byte if you want to string sniff like this outside of Regex)
• Passes @MichaelLiu 's excellent test case, "œ".ReplaceCaseInsensitiveFind("oe", ""), though he may have had a slightly different behavior in mind.

Unfortunately, @HA 's comment that you have to Escape all three isn't correct. The initial value and newValue doesn't need to be.

Note: You do, however, have to escape $s in the new value that you're inserting if they're part of what would appear to be a "captured value" marker. Thus the three dollar signs in the Regex.Replace inside the Regex.Replace [sic]. Without that, something like this breaks...

"This is HIS fork, hIs spoon, hissssssss knife.".ReplaceCaseInsensitiveFind("his", @"he$0r")

Here's the error:

An unhandled exception of type 'System.ArgumentException' occurred in System.dll

Additional information: parsing "The\hisr\ is\ he\HISr\ fork,\ he\hIsr\ spoon,\ he\hisrsssssss\ knife\." - Unrecognized escape sequence \h.

Tell you what, I know folks that are comfortable with Regex feel like their use avoids errors, but I'm often still partial to byte sniffing strings (but only after having read Spolsky on encodings) to be absolutely sure you're getting what you intended for important use cases. Reminds me of Crockford on "insecure regular expressions" a little. Too often we write regexps that allow what we want (if we're lucky), but unintentionally allow more in (eg, Is $10 really a valid "capture value" string in my newValue regexp, above?) because we weren't thoughtful enough. Both methods have value, and both encourage different types of unintentional errors. It's often easy to underestimate complexity.

That weird $ escaping (and that Regex.Escape didn't escape captured value patterns like $0 as I would have expected in replacement values) drove me mad for a while. Programming Is Hard (c) 1842

No need for sub-process, It can be simply achieved by

Here's the code with parameter labels

def draw_text(self, frame, text, x, y, color=BGR_COMMON['green'], thickness=1.3, size=0.3,):

        cv2.putText(
            frame, text, (int(x), int(y)), cv2.FONT_HERSHEY_SIMPLEX, size, color, thickness)

For font name please see another answer in this thread.

Excerpt from answer by @Roeffus

This is indeed a bit of an annoying problem. For python 2.x.x you use:

cv2.CV_FONT_HERSHEY_SIMPLEX and for Python 3.x.x:

cv2.FONT_HERSHEY_SIMPLEX

For more see this http://www.programcreek.com/python/example/83399/cv2.putText

I figured it out. I was using a bad example I found in the past of how to map query string to the method parameters.

In case anyone else needs it, in order to have optional parameters in a query string such as:

• ~/api/products/filter?apc=AA&xpc=BB
• ~/api/products/filter?sku=7199123

you would use:

[Route("products/filter/{apc?}/{xpc?}/{sku?}")]
public IHttpActionResult Get(string apc = null, string xpc = null, int? sku = null)
{ ... }

It seems odd to have to define default values for the method parameters when these types already have a default.

kue is the only message queue you would ever need

For a Fragment you can simply add

  getActivity().onBackPressed();

to your code

I am posting a complete example which I finally got working. Here I am reading in a file rooms/rooms.txt from a script rooms/rooms.js

var fs = require('fs');
var path = require('path');
var readStream = fs.createReadStream(path.join(__dirname, '../rooms') + '/rooms.txt', 'utf8');
let data = ''
readStream.on('data', function(chunk) {
    data += chunk;
}).on('end', function() {
    console.log(data);
});

You can get textbox value and Id by the following simple example in dotNet programming

<html>
        <head>
         <script type="text/javascript">
             function GetTextboxId_Value(textBox) 
                 {
                 alert(textBox.value);    // To get Text Box Value(Text)
                 alert(textBox.id);      // To get Text Box Id like txtSearch
             }
         </script>     
        </head>
 <body>
 <input id="txtSearch" type="text" onkeyup="GetTextboxId_Value(this)" />  </body>
 </html>

After 2 hrs of net surfing Finally For me the problem was fixed by creating a folder pip, with a file: pip.ini in C:\Users<username>\AppData\Roaming\ e.g:

C:\Users\<username>\AppData\Roaming\pip\pip.ini

Inside it I wrote:

[global]
trusted-host = pypi.python.org
pypi.org
files.pythonhosted.org

I restarted python, and then pip permanently trusted these sites, and used them to download packages from.

If you can't find the AppData Folder on windows, write %appdata% in file explorer and it should appear.

Source : pip install fails with "connection error: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:598)"

You could try this:

{% if not profile.user.first_name.value %}
  <p> -- </p>
{% else %}
  {{ profile.user.first_name }} {{ profile.user.last_name }}
{% endif %}

This way, you're essentially checking to see if the form field first_name has any value associated with it. See {{ field.value }} in Looping over the form's fields in Django Documentation.

I'm using Django 3.0.

It's not possible with Notepad but HERE'S THE EASY SOLUTION:

You will need the freeware Expresso v3.1 http://www.ultrapico.com/ExpressoDownload.htm

I resorted to another piece of free software: Expresso by Ultrapico.

1. Once installed go in the tab "Test Mode".
2. Copy your REGEX into the "Regular expressions" pane.

3. Paste your whole text to be searched into the "Sample text" pane of Expresso,

4. Press the "Run match" button. Right click in the "Search results pane" and "Export to..." or "Copy matched text to clipboard".

You need to use IFS instead of -d:

while IFS=, read -r col1 col2
do
    echo "I got:$col1|$col2"
done < myfile.csv

Note that for general purpose CSV parsing you should use a specialized tool which can handle quoted fields with internal commas, among other issues that Bash can't handle by itself. Examples of such tools are cvstool and csvkit.

You can use element.getBoundingClientRect() to retrieve element position relative to the viewport.

Then use document.documentElement.scrollTop to calculate the viewport offset.

The sum of the two will give the element position relative to the document:

element.getBoundingClientRect().top + document.documentElement.scrollTop

While mosca1337's answer is a correct solution, be careful with that method. For a header with text longer than one line, you will have to perform the calculations of the height of the header in tableView:heightForHeaderInSection: which can be cumbersome.

A much preferred method is to use the appearance API:

[[UILabel appearanceWhenContainedIn:[UITableViewHeaderFooterView class], nil] setFont:[UIFont boldSystemFontOfSize:28]];

This will change the font, while still leaving the table to manage the heights itself.

For optimal results, subclass the table view, and add it to the containment chain (in appearanceWhenContainedIn:) to make sure the font is only changed for the specific table views.

There are two ways to resolve this, and only one may work, depending on how you're accessing Google.

The first method is to authorize access for your IP or client machine using the https://accounts.google.com/DisplayUnlockCaptcha link. That can resolve authentication issues on client devices, like mobile or desktop apps. I would test this first, because it results in a lower overall decrease in account security.

If the above link doesn't work, it's because the session is being initiated by an app or device that is not associated with your particular location. Examples include:

• An app that uses a remote server to retrieve data, like a web site or, in my case, other Google servers
• A company mail server fetching mail on your behalf

In all such cases you have to use the https://www.google.com/settings/security/lesssecureapps link referenced above.

TLDR; check the captcha link first, and if it doesn't work, try the other one and enable less secure apps.

I know it is late but I just want to share on what I have done for this. I'm not allowed to add another table or trigger so I need to generate it in a single query upon insert. For your case, can you try this query.

CREATE TABLE YOURTABLE(
IDNUMBER VARCHAR(7) NOT NULL PRIMARY KEY,
ENAME VARCHAR(30) not null
);

Perform a select and use this select query and save to the parameter @IDNUMBER

(SELECT IFNULL
     (CONCAT('LHPL',LPAD(
       (SUBSTRING_INDEX
        (MAX(`IDNUMBER`), 'LHPL',-1) + 1), 5, '0')), 'LHPL001')
    AS 'IDNUMBER' FROM YOURTABLE ORDER BY `IDNUMBER` ASC)

And then Insert query will be :

INSERT INTO YOURTABLE(IDNUMBER, ENAME) VALUES 
(@IDNUMBER, 'EMPLOYEE NAME');

The result will be the same as the other answer but the difference is, you will not need to create another table or trigger. I hope that I can help someone that have a same case as mine.

Using INDEX and MATCH for binning. Easier to maintain if we have more bins.

=INDEX({"Text 1","Text 2","Text 3"},MATCH(A2,{0,5,21,100}))

I am using spring boot 2.0 and I fixed this by replacing @ComponentScan with @EntityScan

instanceof works on instances, i.e. on Objects. Sometimes you want to work directly with classes. In this case you can use the asSubClass method of the Class class. Some examples:

1)

    Class o=Object.class;
    Class c=Class.forName("javax.swing.JFrame").asSubclass(o);

this will go through smoothly because JFrame is subclass of Object. c will contain a Class object representing the JFrame class.

2)

    Class o=JButton.class;
    Class c=Class.forName("javax.swing.JFrame").asSubclass(o);

this will launch a java.lang.ClassCastException because JFrame is NOT subclass of JButton. c will not be initialized.

3)

    Class o=Serializable.class;
    Class c=Class.forName("javax.swing.JFrame").asSubclass(o);

this will go through smoothly because JFrame implements the java.io.Serializable interface. c will contain a Class object representing the JFrame class.

Of course the needed imports have to be included.

Although this is an old question, I had the same question when using the Standard console version. The answer can be found in the Debian Live manual under the section 10.1 Customizing the live user. It says:

It is also possible to change the default username "user" and the default password "live".

I tried the username user and password live and it did work. If you want to run commands as root you can preface each command with sudo

For those who are using Oracle 12.1.0 for development purposes:
I found that the above methods would have no effect on the db user: "system", because the account_status would remain in the expired-grace period.

The easiest solution was for me to use SQL Developer:
within SQL Developer, I had to go to: View / DBA / Security and then Users / System and then on the right side: Actions / Expire pw and then: Actions / Edit and I could untick the option for expired.

This cleared the account_status, it shows OPEN again, and the SQL Developer is no longer showing the ORA-28002 message.

I haven't worked much with Appcelerator Titanium, but I'll put my understanding of it at the end.

I can speak a bit more to the differences between PhoneGap and Xamarin, as I work with these two 5 (or more) days a week.

If you are already familiar with C# and JavaScript, then the question I guess is, does the business logic lie in an area more suited to JavaScript or C#?

PhoneGap

PhoneGap is designed to allow you to write your applications using JavaScript and HTML, and much of the functionality that they do provide is designed to mimic the current proposed specifications for the functionality that will eventually be available with HTML5. The big benefit of PhoneGap in my opinion is that since you are doing the UI with HTML, it can easily be ported between platforms. The downside is, because you are porting the same UI between platforms, it won't feel quite as at home in any of them. Meaning that, without further tweaking, you can't have an application that feels fully at home in iOS and Android, meaning that it has the iOS and Android styling. The majority of your logic can be written using JavaScript, which means it too can be ported between platforms. If the current PhoneGap API does most of what you want, then it's pretty easy to get up and running. If however, there are things you need from the device that are not in the API, then you get into the fun of Plugin Development, which will be in the native device's development language of choice (with one caveat, but I'll get to that), which means you would likely need to get up to speed quickly in Objective-C, Java, etc. The good thing about this model, is you can usually adapt many different native libraries to serve your purpose, and many libraries already have PhoneGap Plugins. Although you might not have much experience with these languages, there will at least be a plethora of examples to work from.

Xamarin

Xamarin.iOS and Xamarin.Android (also known as MonoTouch and MonoDroid), are designed to allow you to have one library of business logic, and use this within your application, and hook it into your UI. Because it's based on .NET 4.5, you get some awesome lambda notations, LINQ, and a whole bunch of other C# awesomeness, which can make writing your business logic less painful. The downside here is that Xamarin expects that you want to make your applications truly feel native on the device, which means that you will likely end up rewriting your UI for each platform, before hooking it together with the business logic. I have heard about MvvmCross, which is designed to make this easier for you, but I haven't really had an opportunity to look into it yet. If you are familiar with the MVVM system in C#, you may want to have a look at this. When it comes to native libraries, MonoTouch becomes interesting. MonoTouch requires a Binding library to tell your C# code how to link into the underlying Objective-C and Java code. Some of these libraries will already have bindings, but if yours doesn't, creating one can be, interesting. Xamarin has made a tool called Objective Sharpie to help with this process, and for the most part, it will get you 95% of the way there. The remaining 5% will probably take 80% of your time attempting to bind a library.

Update

As noted in the comments below, Xamarin has released Xamarin Forms which is a cross platform abstraction around the platform specific UI components. Definitely worth the look.

PhoneGap / Xamarin Hybrid

Now because I said I would get to it, the caveat mentioned in PhoneGap above, is a Hybrid approach, where you can use PhoneGap for part, and Xamarin for part. I have quite a bit of experience with this, and I would caution you against it. Highly. The problem with this, is it is such a no mans' land that if you ever run into issues, almost no one will have come close to what you're doing, and will question what you're trying to do greatly. It is doable, but it's definitely not fun.

Appcelerator Titanium

As I mentioned before, I haven't worked much with Appcelerator Titanium, So for the differences between them, I will suggest you look at Comparing Titanium and Phonegap or Comparison between Corona, Phonegap, Titanium as it has a very thorough description of the differences. Basically, it appears that though they both use JavaScript, how that JavaScript is interpreted is slightly different. With Titanium, you will be writing your JavaScript to the Titanium SDK, whereas with PhoneGap, you will write your application using the PhoneGap API. As PhoneGap is very HTML5 and JavaScript standards compliant, you can use pretty much any JavaScript libraries you want, such as JQuery. With PhoneGap your user interface will be composed of HTML and CSS. With Titanium, you will benefit from their Cross-platform XML which appears to generate Native components. This means it will definitely have a better native look and feel.

        myWebView.goBack()
        return true
    }
    // If it wasn't the Back key or there's no web page history, bubble up to the default

Location of JRE in Ubuntu:

It appears you could use a list instead of a tuple. This becomes more important I think when you are grabbing attributes instead of 'magic indexes' of a list/tuple.

In my case I wanted to sort by multiple attributes of a class, where the incoming keys were strings. I needed different sorting in different places, and I wanted a common default sort for the parent class that clients were interacting with; only having to override the 'sorting keys' when I really 'needed to', but also in a way that I could store them as lists that the class could share

So first I defined a helper method

def attr_sort(self, attrs=['someAttributeString']:
  '''helper to sort by the attributes named by strings of attrs in order'''
  return lambda k: [ getattr(k, attr) for attr in attrs ]

then to use it

# would defined elsewhere but showing here for consiseness
self.SortListA = ['attrA', 'attrB']
self.SortListB = ['attrC', 'attrA']
records = .... #list of my objects to sort
records.sort(key=self.attr_sort(attrs=self.SortListA))
# perhaps later nearby or in another function
more_records = .... #another list
more_records.sort(key=self.attr_sort(attrs=self.SortListB))

This will use the generated lambda function sort the list by object.attrA and then object.attrB assuming object has a getter corresponding to the string names provided. And the second case would sort by object.attrC then object.attrA.

This also allows you to potentially expose outward sorting choices to be shared alike by a consumer, a unit test, or for them to perhaps tell you how they want sorting done for some operation in your api by only have to give you a list and not coupling them to your back end implementation.

HashMap is unordered per the second line of the documentation:

This class makes no guarantees as to the order of the map; in particular, it does not guarantee that the order will remain constant over time.

Perhaps you can do as aix suggests and use a LinkedHashMap, or another ordered collection. This link can help you find the most appropriate collection to use.

I know this is an old thread, but I just stumbled upon it and I feel this has not been explained completely.

There is a huge difference in SQL*Plus between the meaning of a / and a ; because they work differently.

The ; ends a SQL statement, whereas the / executes whatever is in the current "buffer". So when you use a ; and a / the statement is actually executed twice.

You can easily see that using a / after running a statement:

SQL> drop table foo;

Table dropped.

SQL> /
drop table foo
           *
ERROR at line 1:
ORA-00942: table or view does not exist

In this case one actually notices the error.


But assuming there is a SQL script like this:

drop table foo;
/

And this is run from within SQL*Plus then this will be very confusing:

The / is mainly required in order to run statements that have embedded ; like a CREATE PROCEDURE statement.

Ok here is what I do

sys.argv is always what you type into the terminal or use as the file path when executing it with python.exe or pythonw.exe

For example you can run the file text.py several ways, they each give you a different answer they always give you the path that python was typed.

    C:\Documents and Settings\Admin>python test.py
    sys.argv[0]: test.py
    C:\Documents and Settings\Admin>python "C:\Documents and Settings\Admin\test.py"
    sys.argv[0]: C:\Documents and Settings\Admin\test.py

Ok so know you can get the file name, great big deal, now to get the application directory you can know use os.path, specifically abspath and dirname

    import sys, os
    print os.path.dirname(os.path.abspath(sys.argv[0]))

That will output this:

   C:\Documents and Settings\Admin\

it will always output this no matter if you type python test.py or python "C:\Documents and Settings\Admin\test.py"

The problem with using __file__ Consider these two files test.py

import sys
import os

def paths():
        print "__file__: %s" % __file__
        print "sys.argv: %s" % sys.argv[0]

        a_f = os.path.abspath(__file__)
        a_s = os.path.abspath(sys.argv[0])

        print "abs __file__: %s" % a_f
        print "abs sys.argv: %s" % a_s

if __name__ == "__main__":
    paths()

import_test.py

import test
import sys

test.paths()

print "--------"
print __file__
print sys.argv[0]

Output of "python test.py"

C:\Documents and Settings\Admin>python test.py
__file__: test.py
sys.argv: test.py
abs __file__: C:\Documents and Settings\Admin\test.py
abs sys.argv: C:\Documents and Settings\Admin\test.py

Output of "python test_import.py"

C:\Documents and Settings\Admin>python test_import.py
__file__: C:\Documents and Settings\Admin\test.pyc
sys.argv: test_import.py
abs __file__: C:\Documents and Settings\Admin\test.pyc
abs sys.argv: C:\Documents and Settings\Admin\test_import.py
--------
test_import.py

So as you can see file gives you always the python file it is being run from, where as sys.argv[0] gives you the file that you ran from the interpreter always. Depending on your needs you will need to choose which one best fits your needs.

To understand sed command, we have to build it step by step.

Here is your original text

user@linux:~$ echo "Here is a String"
Here is a String
user@linux:~$ 

Let's try to remove Here string with substition option in sed

user@linux:~$ echo "Here is a String" | sed 's/Here //'
is a String
user@linux:~$ 

At this point, I believe you would be able to remove String as well

user@linux:~$ echo "Here is a String" | sed 's/String//'
Here is a
user@linux:~$ 

But this is not your desired output.

To combine two sed commands, use -e option

user@linux:~$ echo "Here is a String" | sed -e 's/Here //' -e 's/String//'
is a
user@linux:~$ 

Hope this helps

While using TOP or a sub-query both work, I would break the problem into steps:

Find target record

SELECT MIN( date ) AS date, id
FROM myTable
WHERE id = 2
GROUP BY id

Join to get other fields

SELECT mt.id, mt.name, mt.score, mt.date
FROM myTable mt
INNER JOIN
( 
   SELECT MIN( date ) AS date, id
   FROM myTable
   WHERE id = 2
   GROUP BY id
) x ON x.date = mt.date AND x.id = mt.id

While this solution, using derived tables, is longer, it is:

• Easier to test
• Self documenting
• Extendable

It is easier to test as parts of the query can be run standalone.

It is self documenting as the query directly reflects the requirement ie the derived table lists the row where id = 2 with the earliest date.

It is extendable as if another condition is required, this can be easily added to the derived table.

On saveAndFlush, changes will be flushed to DB immediately in this command. With save, this is not necessarily true, and might stay just in memory, until flush or commit commands are issued.

But be aware, that even if you flush the changes in transaction and do not commit them, the changes still won't be visible to the outside transactions until the commit in this transaction.

In your case, you probably use some sort of transactions mechanism, which issues commit command for you if everything works out fine.

This is a BAD way to do it! I'm only leaving this answer in case it solves other weird problems. These better methods are the probably partly the result of newer data.table versions... so it's worth while to document this hard way. Plus, this is a nice syntax example for eval substitute syntax.

library(data.table)
dt <- data.table(ID = c(rep("A", 5), rep("B",5)), 
                 fac1 = c(1:5, 1:5), 
                 fac2 = c(1:5, 1:5) * 2, 
                 val1 = rnorm(10),
                 val2 = rnorm(10))

names_factors = c('fac1', 'fac2')
names_values = c('val1', 'val2')

for (col in names_factors){
  e = substitute(X := as.factor(X), list(X = as.symbol(col)))
  dt[ , eval(e)]
}
for (col in names_values){
  e = substitute(X := as.numeric(X), list(X = as.symbol(col)))
  dt[ , eval(e)]
}

str(dt)

which gives you

Classes ‘data.table’ and 'data.frame':  10 obs. of  5 variables:
 $ ID  : chr  "A" "A" "A" "A" ...
 $ fac1: Factor w/ 5 levels "1","2","3","4",..: 1 2 3 4 5 1 2 3 4 5
 $ fac2: Factor w/ 5 levels "2","4","6","8",..: 1 2 3 4 5 1 2 3 4 5
 $ val1: num  0.0459 2.0113 0.5186 -0.8348 -0.2185 ...
 $ val2: num  -0.0688 0.6544 0.267 -0.1322 -0.4893 ...
 - attr(*, ".internal.selfref")=<externalptr> 

1. Set var step=1 as global variable by putting it above the function call
2. put semicolons

It will look like this

<head>
<script type="text/javascript">
var image1 = new Image()
image1.src = "images/pentagg.jpg"
var image2 = new Image()
image2.src = "images/promo.jpg"
</script>
</head>
<body>
<p><img src="images/pentagg.jpg" width="500" height="300" name="slide" /></p>
<script type="text/javascript">
        var step=1;
        function slideit()
        {
            document.images.slide.src = eval("image"+step+".src");
            if(step<2)
                step++;
            else
                step=1;
            setTimeout("slideit()",2500);
        }
        slideit();
</script>
</body>

Sometimes you just need to optimize your code or query, Setting more max_execution_time is not a solution.

It is not suggested to take more than 30 for loading a webpage if a task takes more time need to be a queue.

I was encountering the following error: The requested package my-foo/bar could not be found in any version, there may be a typo in the package name.

If you're forking another repo to make your own changes you will end up with a new repository.

E.g:

https://github.com/foo/bar.git
=>
https://github.com/my-foo/bar.git

The new url will need to go into your repositories section of your composer.json.

Remember if you want refer to your fork as my-foo/bar in your require section, you will have to rename the package in the composer.json file inside of your new repo.

{
    "name":         "foo/bar",

=>

{
    "name":         "my-foo/bar",

If you've just forked the easiest way to do this is edit it right inside github.

Generally, this will be dependent on the interface the connection is using. You can probably use an ioctl() to get the MTU, and if it is ethernet, you can usually get the maximum packet size by subtracting the size of the hardware header from that, which is 14 for ethernet with no VLAN.

This is only the case if the MTU is at least that large across the network. TCP may use path MTU discovery to reduce your effective MTU.

The question is, why do you care?

The rgba() function can accept a single hex color as well decimal RGB values. For example, this would work just fine:

@mixin background-opacity($color, $opacity: 0.3) {
    background: $color; /* The Fallback */
    background: rgba($color, $opacity);
}

element {
     @include background-opacity(#333, 0.5);
}

If you ever need to break the hex color into RGB components, though, you can use the red(), green(), and blue() functions to do so:

$red: red($color);
$green: green($color);
$blue: blue($color);

background: rgb($red, $green, $blue); /* same as using "background: $color" */

Just use:

overflow: hidden;
white-space: nowrap;

In your item's divs

how to get count column

final String DATABASE_COMPARE = "select count(*) from users where uname="+loginname+ "and pwd="+loginpass;

int sometotal = (int) DatabaseUtils.longForQuery(db, DATABASE_COMPARE, null);

This is the most concise and precise alternative. No need to handle cursors and their closing.

this type of error usually occur when you try to access data through the index in which data data has not been assign. for example

//assign of data in to array
for(int i=0; i<10; i++){
   arr[i]=i;
}
//accessing of data through array index
for(int i=10; i>=0; i--){
cout << arr[i];
}

the code will give error (vector subscript out of range) because you are accessing the arr[10] which has not been assign yet.

Try out below code snippet:

 var list = [];
 var text;

function update() {
    console.log(list);    

    for (var i = 0; i < list.length; i++) {
       console.log( i );
       var letters;
       var ul = document.getElementById("list");
       var li = document.createElement("li");

       li.appendChild(document.createTextNode(list[i]));
       ul.appendChild(li);

       letters += "<li>"  + list[i] + "</li>";
    }

 document.getElementById("list").innerHTML = letters;

}

function myFunction() {
    text = prompt("enter TODO");  
    list.push(text);
    update();
}   

There is a single quote in $submitsubject or $submit_message

Why is this a problem?

The single quote char terminates the string in MySQL and everything past that is treated as a sql command. You REALLY don't want to write your sql like that. At best, your application will break intermittently (as you're observing) and at worst, you have just introduced a huge security vulnerability.

Imagine if someone submitted '); DROP TABLE private_messages; in submit message.

Your SQL Command would be:

INSERT INTO private_messages (to_id, from_id, time_sent, subject, message) 
        VALUES('sender_id', 'id', now(),'subjet','');

DROP TABLE private_messages;

Instead you need to properly sanitize your values.

AT A MINIMUM you must run each value through mysql_real_escape_string() but you should really be using prepared statements.

If you were using mysql_real_escape_string() your code would look like this:

if($_POST['submit_message']){

if($_POST['form_subject']==""){
    $submit_subject="(no subject)";
}else{
    $submit_subject=mysql_real_escape_string($_POST['form_subject']); 
}
$submit_message=mysql_real_escape_string($_POST['form_message']);
$sender_id = mysql_real_escape_string($_POST['sender_id']);

Here is a great article on prepared statements and PDO.

Well, it's JavaScript, so what you have in 'value' is a Number, which can be an integer or a float. But there's not really a difference in JavaScript. From Learning JavaScript:

The Number Data Type

Number data types in JavaScript are floating-point numbers, but they may or may not have a fractional component. If they don’t have a decimal point or fractional component, they’re treated as integers—base-10 whole numbers in a range of –2⁵³ to 2⁵³.

Simple:

    dim input as string = "SPQR"
    dim format as string =""
    dim result as string = ""

    'pad left:
    format = "{0,-8}"
    result = String.Format(format,input)
    'result = "SPQR    "

    'pad right
    format = "{0,8}"
    result = String.Format(format,input)
    'result = "    SPQR"

Or, if you're kicking it old school:

cd /path/to/other/repository
patch -p1 < 0001-whatever.patch

I had the same problem.

Here is a workaround

android:inputType="textNoSuggestions|textVisiblePassword"
android:maxLength="6"

Thx to How can I turnoff suggestions in EditText?

You should add first jquery.cookie.js then add your js or jQuery where you are using that function.

When browser loads the webpage first it loads this jquery.cookie.js and after then you js or jQuery and now that function is available for use

You can use strcmp:

break x:20 if strcmp(y, "hello") == 0

20 is line number, x can be any filename and y can be any variable.

size_t is the size of a pointer.

So in 32 bits or the common ILP32 (integer, long, pointer) model size_t is 32 bits. and in 64 bits or the common LP64 (long, pointer) model size_t is 64 bits (integers are still 32 bits).

There are other models but these are the ones that g++ use (at least by default)

It is due to android:targetSdkVersion="@string/app_name" in your manifiest file.
Change it to:

<uses-sdk android:minSdkVersion="15" android:targetSdkVersion="15"/>

The targetSdkVersion should be an integer, but @string/app_name would be a string. I think this causing the error.

EDIT:
You have to add a default intent-filter in your manifiest file for the activity. Then only android can launch the activity. otherwise you will get the below error in your console window.

[2012-02-02 09:17:39 - Test] No Launcher activity found!
[2012-02-02 09:17:39 - Test] The launch will only sync the application package on the device!

Add the following to your <activity> tag.

<activity android:name="HelloAndroid" android:launchMode="standard" android:enabled="true">  
  <intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
  </intent-filter>
</activity>

I think you can use REGEXP instead of LIKE

SELECT trecord FROM `tbl` WHERE (trecord REGEXP '^ALA[0-9]')

Thing is, the code you provided won't work because the <iframe> element has to have a "src" property, like:

<iframe id="uploads" src="http://domain/page.html"></iframe>

It's ok to use .contents() to get the content:

$('#uploads).contents() will give you access to the second iframe, but if that iframe is "INSIDE" the http://domain/page.html document the #uploads iframe loaded.

To test I'm right about this, I created 3 html files named main.html, iframe.html and noframe.html and then selected the div#element just fine with:

$('#uploads').contents().find('iframe').contents().find('#element');

There WILL be a delay in which the element will not be available since you need to wait for the iframe to load the resource. Also, all iframes have to be on the same domain.

Hope this helps ...

Here goes the html for the 3 files I used (replace the "src" attributes with your domain and url):

main.html

<!DOCTYPE HTML>
<html>
<head>
    <meta charset="utf-8">
    <title>main.html example</title>

    <script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>

    <script>
        $(function () {
            console.log( $('#uploads').contents().find('iframe').contents().find('#element') ); // nothing at first

            setTimeout( function () {
                console.log( $('#uploads').contents().find('iframe').contents().find('#element') ); // wait and you'll have it
            }, 2000 );

        });
    </script>

    SSLContext sslContext = org.apache.http.ssl.SSLContexts.custom()
                    .loadTrustMaterial(null, acceptingTrustStrategy)
                    .build();

    SSLConnectionSocketFactory csf = new SSLConnectionSocketFactory(sslContext);

    CloseableHttpClient httpClient = HttpClients.custom()

    return restTemplate;
 }

You can't do it with only Javascript. You'll need some server-side code (PHP, in your case) that serves as a proxy between the DB and the client-side code.

I wasn't happy with any of these answers, and the one that's right has no explanation and negative votes so I searched around, found some stuff and edited it so that it is easy to understand. Have a play with it, not as straight forward as one would hope.

//move your variable into an Object type
Object obj=whatYouAreChecking;
System.out.println(obj);

// moving the class type into a Class variable
Class cls=obj.getClass();
System.out.println(cls);

// convert that Class Variable to a neat String
String answer = cls.getSimpleName();
System.out.println(answer);

Here is a method:

public static void checkClass (Object obj) {
    Class cls = obj.getClass();
    System.out.println("The type of the object is: " + cls.getSimpleName());       
}

Do not use "system("Color …")" if you don't want the entire screen to be filled up with color. This is the script needed to make colored text:

#include <iostream>
#include <windows.h>

int main()
{
const WORD colors[] =
{
0x1A, 0x2B, 0x3C, 0x4D, 0x5E, 0x6F,
0xA1, 0xB2, 0xC3, 0xD4, 0xE5, 0xF6
};

HANDLE hstdin = GetStdHandle(STD_INPUT_HANDLE);
HANDLE hstdout = GetStdHandle(STD_OUTPUT_HANDLE);
WORD   index = 0;


    SetConsoleTextAttribute(hstdout, colors[index]);
    std::cout << "Hello world" << std::endl;
FlushConsoleInputBuffer(hstdin);
return 0;
}

** Update ** A scalars converter has been added to retrofit that allows for a String response with less ceremony than my original answer below.

Example interface --

public interface GitHubService {
    @GET("/users/{user}")
    Call<String> listRepos(@Path("user") String user);
}

Add the ScalarsConverterFactory to your retrofit builder. Note: If using ScalarsConverterFactory and another factory, add the scalars factory first.

Retrofit retrofit = new Retrofit.Builder()
    .baseUrl(BASE_URL)
    .addConverterFactory(ScalarsConverterFactory.create())
    // add other factories here, if needed.
    .build();

You will also need to include the scalars converter in your gradle file --

implementation 'com.squareup.retrofit2:converter-scalars:2.1.0'

--- Original Answer (still works, just more code) ---

I agree with @CommonsWare that it seems a bit odd that you want to intercept the request to process the JSON yourself. Most of the time the POJO has all the data you need, so no need to mess around in JSONObject land. I suspect your specific problem might be better solved using a custom gson TypeAdapter or a retrofit Converter if you need to manipulate the JSON. However, retrofit provides more the just JSON parsing via Gson. It also manages a lot of the other tedious tasks involved in REST requests. Just because you don't want to use one of the features, doesn't mean you have to throw the whole thing out. There are times you just want to get the raw stream, so here is how to do it -

First, if you are using Retrofit 2, you should start using the Call API. Instead of sending an object to convert as the type parameter, use ResponseBody from okhttp --

public interface GitHubService {
    @GET("/users/{user}")
    Call<ResponseBody> listRepos(@Path("user") String user);
}

then you can create and execute your call --

GitHubService service = retrofit.create(GitHubService.class);
Call<ResponseBody> result = service.listRepos(username);
result.enqueue(new Callback<ResponseBody>() {
    @Override
    public void onResponse(Response<ResponseBody> response) {
        try {
            System.out.println(response.body().string());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    @Override
    public void onFailure(Throwable t) {
        e.printStackTrace();
    }
});

Note The code above calls string() on the response object, which reads the entire response into a String. If you are passing the body off to something that can ingest streams, you can call charStream() instead. See the ResponseBody docs.

Hello just create a simple function that looks as shown below.. That returns all rows where the call parameter entered is valid or true.

 public  DataTable SearchRecords(string Col1, DataTable RecordDT_, int KeyWORD)
    {
        TempTable = RecordDT_;
        DataView DV = new DataView(TempTable);
        DV.RowFilter = string.Format(string.Format("Convert({0},'System.String')",Col1) + " LIKE '{0}'", KeyWORD);
        return DV.ToTable();
    }

and simply call it as shown below;

  DataTable RowsFound=SearchRecords("IdColumn", OriginalTable,5);

where 5 is the ID. Thanks..

I renamed the config file and restarted server:

$ mv /etc/php/7.0/fpm/conf.d/20-xdebug.ini /etc/php/7.0/fpm/conf.d/20-xdebug.ini.bak

$ sudo service php7.0-fpm restart && sudo service nginx restart

It did work for me.

This is how I got the H2 console working in spring-boot with H2. I am not sure if this is right but since no one else has offered a solution then I am going to suggest this is the best way to do it.

In my case, I chose a specific name for the database so that I would have something to enter when starting the H2 console (in this case, "AZ"). I think all of these are required though it seems like leaving out the spring.jpa.database-platform does not hurt anything.

In application.properties:

spring.datasource.url=jdbc:h2:mem:AZ;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.username=sa
spring.datasource.password=
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect

In Application.java (or some configuration):

@Bean
public ServletRegistrationBean h2servletRegistration() {
    ServletRegistrationBean registration = new ServletRegistrationBean(new WebServlet());
    registration.addUrlMappings("/console/*");
    return registration;
}

Then you can access the H2 console at {server}/console/. Enter this as the JDBC URL: jdbc:h2:mem:AZ

Here's the steps (my non-computer-savvy girlfriend had to figure this one out for me, but unlike all the far more complicated processes one can find online, this one works)

1. Open Control Panel
2. Click "Uninstall a Program"
3. Scroll down to Python and click uninstall for each version you don't want anymore.

This works on Windows 7 out of the box, no additional programs or scripts required.

Here's your method:

public static Calendar toCalendar(Date date){ 
  Calendar cal = Calendar.getInstance();
  cal.setTime(date);
  return cal;
}

Everything else you are doing is both wrong and unnecessary.

BTW, Java Naming conventions suggest that method names start with a lower case letter, so it should be: dateToCalendar or toCalendar (as shown).

OK, let's milk your code, shall we?

DateFormat formatter = new SimpleDateFormat("yyyyMMdd");
date = (Date)formatter.parse(date.toString()); 

DateFormat is used to convert Strings to Dates (parse()) or Dates to Strings (format()). You are using it to parse the String representation of a Date back to a Date. This can't be right, can it?

Some notes to complement the ALTER DATABASE process:

1) You can obtain a full list of databases with logical names and full paths of MDF and LDF files:

   USE master SELECT name, physical_name FROM sys.master_files

2) You can move manually the files with CMD move command:

Move "Source" "Destination"

Example:

md "D:\MSSQLData"
Move "C:\test\SYSADMIT-DB.mdf" "D:\MSSQLData\SYSADMIT-DB_Data.mdf"
Move "C:\test\SYSADMIT-DB_log.ldf" "D:\MSSQLData\SYSADMIT-DB_log.ldf"

3) You should change the default database path for new databases creation. The default path is obtained from the Windows registry.

You can also change with T-SQL, for example, to set default destination to: D:\MSSQLData

USE [master]

If you wanted to you could use this method, which is a bit hacky, but would offer the desired functionality:

jQuery('<a/>', {
    id: 'foo',
    href: 'http://google.com',
    title: 'Become a Googler',
    rel: 'external',
    text: 'Go to Google!',
    target:'_blank',
    style:'display:none;'
}).appendTo('#mySelector');

$('#foo').click()

I recommend PyInstaller, a simple python script can be converted to an exe with the following commands:

utils/Makespec.py [--onefile] oldlogs.py

which creates a yourprogram.spec file which is a configuration for building the final exe. Next command builds the exe from the configuration file:

utils/Build.py oldlogs.spec

moment('2020-01-20').isSame('2020-01-20'); // true

To delete all objects in a list, you can directly write list = []

Here is example:

>>> a = [1, 2, 3]
>>> a
[1, 2, 3]
>>> a = []
>>> a
[]

A general solution:

import random
def weighted_choice(choices, weights):
    total = sum(weights)
    treshold = random.uniform(0, total)
    for k, weight in enumerate(weights):
        total -= weight
        if total < treshold:
            return choices[k]

You can use date function to format it by using the code below:

echo date("g:i a", strtotime("13:30:30 UTC"));

output: 1:30 pm

You can find the layers of the images in the folder /var/lib/docker/aufs/layers; provide if you configured for storage-driver as aufs (default option)

Example:

 docker ps -a
 CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                      PORTS               NAMES
 0ca502fa6aae        ubuntu              "/bin/bash"         44 minutes ago      Exited (0) 44 seconds ago                       DockerTest

Now to view the layers of the containers that were created with the image "Ubuntu"; go to /var/lib/docker/aufs/layers directory and cat the file starts with the container ID (here it is 0ca502fa6aae*)

 root@viswesn-vm2:/var/lib/docker/aufs/layers# cat    0ca502fa6aaefc89f690736609b54b2f0fdebfe8452902ca383020e3b0d266f9-init

 83e4dde6b9cfddf46b75a07ec8d65ad87a748b98cf27de7d5b3298c1f3455ae4

This will show the result of same by running

I hope this will serve your purpose.

The Array.prototype.shift method removes the first element from an array, and returns it. It modifies the original array.

var a = [1,2,3]
// [1,2,3]
a.shift()
// 1
a
//[2,3]

import java.util.regex.Matcher;
import java.util.regex.Pattern;

        String mydata = "some string with 'the data i want' inside";

        Matcher matcher = pattern.matcher(mydata);
        if(matcher.matches()) {
            System.out.println(matcher.group(1));
        }

your compilation option -c makes your compiling just compilation and assembly, but no link.

Use the BEGIN TRANSACTION command before starting queries. So that you can ROLLBACK things at any point of time.

FOR EXAMPLE:

1. begin transaction
2. select * from Student
3. delete from Student where Id=2
4. select * from Student
5. rollback
6. select * from Student

Hmm, not sure I agree with Nick re tag being similar to a branch. A tag is just a marker

• Trunk would be the main body of development, originating from the start of the project until the present.

• Branch will be a copy of code derived from a certain point in the trunk that is used for applying major changes to the code while preserving the integrity of the code in the trunk. If the major changes work according to plan, they are usually merged back into the trunk.

• Tag will be a point in time on the trunk or a branch that you wish to preserve. The two main reasons for preservation would be that either this is a major release of the software, whether alpha, beta, RC or RTM, or this is the most stable point of the software before major revisions on the trunk were applied.

In open source projects, major branches that are not accepted into the trunk by the project stakeholders can become the bases for forks -- e.g., totally separate projects that share a common origin with other source code.

The branch and tag subtrees are distinguished from the trunk in the following ways:

Subversion allows sysadmins to create hook scripts which are triggered for execution when certain events occur; for instance, committing a change to the repository. It is very common for a typical Subversion repository implementation to treat any path containing "/tag/" to be write-protected after creation; the net result is that tags, once created, are immutable (at least to "ordinary" users). This is done via the hook scripts, which enforce the immutability by preventing further changes if tag is a parent node of the changed object.

Subversion also has added features, since version 1.5, relating to "branch merge tracking" so that changes committed to a branch can be merged back into the trunk with support for incremental, "smart" merging.

Volatile means other threads can edit that particular variable. So the compiler allows access to them.

http://www.javamex.com/tutorials/synchronization_volatile.shtml

Transient means that when you serialize an object, it will return its default value on de-serialization

http://www.geekinterview.com/question_details/2

Use DATE(NOW()) to compare dates

DATE(NOW()) will give you the date part of current date and DATE(duedate) will give you the date part of the due date. then you can easily compare the dates

So you can compare it like

DATE(NOW()) = DATE(duedate)

OR

DATE(duedate) = CURDATE() 

See here

You can use the ROWLOCK hint, but AFAIK SQL may decide to escalate it if it runs low on resources

From the doco:

ROWLOCK Specifies that row locks are taken when page or table locks are ordinarily taken. When specified in transactions operating at the SNAPSHOT isolation level, row locks are not taken unless ROWLOCK is combined with other table hints that require locks, such as UPDLOCK and HOLDLOCK.

and

Lock hints ROWLOCK, UPDLOCK, AND XLOCK that acquire row-level locks may place locks on index keys rather than the actual data rows. For example, if a table has a nonclustered index, and a SELECT statement using a lock hint is handled by a covering index, a lock is acquired on the index key in the covering index rather than on the data row in the base table.

And finally this gives a pretty in-depth explanation about lock escalation in SQL Server 2005 which was changed in SQL Server 2008.

There is also, the very in depth: Locking in The Database Engine (in books online)

So, in general

UPDATE
Employees WITH (ROWLOCK)
SET Name='Mr Bean'
WHERE Age>93

Should be ok, but depending on the indexes and load on the server it may end up escalating to a page lock.

You can write an object to a file using writeObject in ObjectOutputStream

Here is a nice summary table from cppreference.com:

Here, insertion refers to any method which adds one or more elements to the container and erasure refers to any method which removes one or more elements from the container.

There are two cases in which this error is raised.

1. You didn't declare the variable which is used
2. You didn't create the instances of the class

You need to create a git repo locally, add your project files to that repo, commit them to the local repo, and then sync that repo to your repo on github. You can find good instructions on how to do the latter bit on github, and the former should be easy to do with the software you've downloaded.

This example shows how you can layer SSL on top of an existing socket, obtaining the client cert from a PKCS#12 file. It is appropriate when you need to connect to an upstream server via a proxy, and you want to handle the full protocol by yourself.

Essentially, however, once you have the SSL Context, you can apply it to an HttpsURLConnection, etc, etc.

KeyStore ks = KeyStore.getInstance("PKCS12");
InputStream is = ...;
char[] ksp = storePassword.toCharArray();
ks.load(is, ksp);
KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
char[] kp = keyPassword.toCharArray();
kmf.init(ks, kp);
sslContext = SSLContext.getInstance("SSLv3");
sslContext.init(kmf.getKeyManagers(), null, null);
SSLSocketFactory factory = sslContext.getSocketFactory();
SSLSocket sslsocket = (SSLSocket) factory.createSocket(socket, socket
    .getInetAddress().getHostName(), socket.getPort(), true);
sslsocket.setUseClientMode(true);
sslsocket.setSoTimeout(soTimeout);
sslsocket.startHandshake();

The following worked for me with clang. Allows what appears as symbolic macro value comparison. #error xxx is just to see what compiler really does. Replacing cat definition with #define cat(a,b) a ## b breaks things.

#define cat(a,...) cat_impl(a, __VA_ARGS__)
#define cat_impl(a,...) a ## __VA_ARGS__

#define xUSER_jack 0
#define xUSER_queen 1
#define USER_VAL cat(xUSER_,USER)

#define USER jack // jack or queen

#if USER_VAL==xUSER_jack
  #error USER=jack
  #define USER_VS "queen"
#elif USER_VAL==xUSER_queen
  #error USER=queen
  #define USER_VS "jack"
#endif

1. If Color is something that is specific to just Cars then that is the way you would limit its scope. If you are going to have another Color enum that other classes use then you might as well make it global (or at least outside Car).

2. It makes no difference. If there is a global one then the local one is still used anyway as it is closer to the current scope. Note that if you define those function outside of the class definition then you'll need to explicitly specify Car::Color in the function's interface.

If you haven't committed changes

If your changes are compatible with the other branch

This is the case from the question because the OP wants to commit to a new branch and also applies if your changes are compatible with the target branch without triggering an overwrite.

As in the accepted answer by John Brodie, you can simply checkout the new branch and commit the work:

git checkout -b branch_name
git add <files>
git commit -m "message"

If your changes are incompatible with the other branch

If you get the error:

error: Your local changes to the following files would be overwritten by checkout:
...
Please commit your changes or stash them before you switch branches

Then you can stash your work, create a new branch, then pop your stash changes, and resolve the conflicts:

git stash
git checkout -b branch_name
git stash pop

It will be as if you had made those changes after creating the new branch. Then you can commit as usual:

git add <files>
git commit -m "message"

If you have committed changes

If you want to keep the commits in the original branch

See the answer by Carl Norum with cherry-picking, which is the right tool in this case:

git checkout <target name>
git cherry-pick <original branch>

If you don't want to keep the commits in the original branch

See the answer by joeytwiddle on this potential duplicate. Follow any of the above steps as appropriate, then roll back the original branch:

git branch -f <original branch> <earlier commit id>

If you have pushed your changes to a shared remote like GitHub, you should not attempt this roll-back unless you know what you are doing.

You probably forgot to give # before id for id selector, you need to give # before id ie is ulId

You problably need to bind scroll event on div that contains the ul and scrolls. You need to bind the event with div instead of ul

$(document).on( 'scroll', '#idOfDivThatContainsULandScroll', function(){
    console.log('Event Fired');
});

Edit

The above would not work because the scroll event does not bubble up in DOM which is used for event delegation, see this question why doesn't delegate work for scroll?

But with modern browsers > IE 8 you can do it by other way. Instead of delegating by using jquery you can do it using event capturing with java script document.addEventListener, with the third argument as true; see how bubbling and capturing work in this tuturial.

Live Demo

document.addEventListener('scroll', function (event) {
    if (event.target.id === 'idOfUl') { // or any other filtering condition        
        console.log('scrolling', event.target);
    }
}, true /*Capture event*/);

If you do not need event delegation then you can bind scroll event directly to the ul instead of delegating it through document.

Live Demo

$("#idOfUl").on( 'scroll', function(){
   console.log('Event Fired');
});

Instead of launching the batch directly from explorer - create a shortcut to the batch and set the starting directory in the properties of the shortcut to a local path like %TEMP% or something.

To delete the symbolic link, use the rmdir command.

I took the JAXB.marshal implementation and added jaxb.fragment=true to remove the XML prolog. This method can handle objects even without the XmlRootElement annotation. This also throws the unchecked DataBindingException.

public static String toXmlString(Object o) {
    try {
        Class<?> clazz = o.getClass();
        JAXBContext context = JAXBContext.newInstance(clazz);
        Marshaller marshaller = context.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FRAGMENT, true); // remove xml prolog
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true); // formatted output

        final QName name = new QName(Introspector.decapitalize(clazz.getSimpleName()));
        JAXBElement jaxbElement = new JAXBElement(name, clazz, o);

        StringWriter sw = new StringWriter();
        marshaller.marshal(jaxbElement, sw);
        return sw.toString();

    } catch (JAXBException e) {
        throw new DataBindingException(e);
    }
}

If the compiler warning bothers you, here's the templated, two parameter version.

public static <T> String toXmlString(T o, Class<T> clazz) {
    try {
        JAXBContext context = JAXBContext.newInstance(clazz);
        Marshaller marshaller = context.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FRAGMENT, true); // remove xml prolog
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true); // formatted output

        QName name = new QName(Introspector.decapitalize(clazz.getSimpleName()));
        JAXBElement jaxbElement = new JAXBElement<>(name, clazz, o);

        StringWriter sw = new StringWriter();
        marshaller.marshal(jaxbElement, sw);
        return sw.toString();

    } catch (JAXBException e) {
        throw new DataBindingException(e);
    }
}

I tried all the above methods and I did not get the value properly in the same format, then I found this.

$("#datetimepicker1").find("input")[1].value;

The above code will return the value in the same format as in the datetime picker.

This may help you guys in the future.

Hope this was helpful..

The following can be used from numpy:

import numpy as np 
image = np.array(image)

To bind the data to ComboBox

List<ComboData> ListData = new List<ComboData>();
ListData.Add(new ComboData { Id = "1", Value = "One" });
ListData.Add(new ComboData { Id = "2", Value = "Two" });
ListData.Add(new ComboData { Id = "3", Value = "Three" });
ListData.Add(new ComboData { Id = "4", Value = "Four" });
ListData.Add(new ComboData { Id = "5", Value = "Five" });

cbotest.ItemsSource = ListData;
cbotest.DisplayMemberPath = "Value";
cbotest.SelectedValuePath = "Id";

cbotest.SelectedValue = "2";

ComboData looks like:

public class ComboData
{ 
  public int Id { get; set; } 
  public string Value { get; set; } 
}

(note that Id and Value have to be properties, not class fields)

I am still a beginner at git, and it was just a stupid mistake I made, long story in one sentence. I was not in a subfolder as @gaoagong reported, but the other way round, in a parent folder. Strange enough, I did not get the idea from that answer, instead, the idea came up when I tested git add --all, see the long story below.

Example in details. Actual repo:

The Parent folder that I had opened mistakenly on parent level (vscode_git in my case):

I had cloned a repo, but I had a parent folder above this repo which I had opened instead, and then I tried adding a file of the subfolder's repo with git add 'd:\Stack Overflow\vscode_git\vscode-java\.github\ISSUE_TEMPLATE.md', which simply did nothing, no warning message, and the git status afterwards said:

nothing added to commit but untracked files present (use "git add" to track)

Running git add --all gave me the yellow notes:

warning: adding embedded git repository: vscode-java the embedded repository and will not know how to obtain it.

hint: If you meant to add a submodule, use: git submodule add vscode-java

hint: If you added this path by mistake, you can remove it from the index with git rm --cached vscode-java

See "git help submodule" for more information.git

To fix this, I reverted the git add --all with git rm --cached -r -f -- "d:\Stack Overflow\vscode_git\vscode-java" rm 'vscode-java':

Then, by simply opening the actual repo folder instead,

the git worked as expected again. Of course the ".git" folder of the parent folder could be deleted then:

If you want the second highest number you can use

=LARGE(E4:E9;2)

although that doesn't account for duplicates so you could get the same result as the Max

If you want the largest number that is smaller than the maximum number you can use this version

=LARGE(E4:E9;COUNTIF(E4:E9;MAX(E4:E9))+1)

You could also use indexOf instead to do this

var i = review.indexOf('\u2022 \u2022 \u2022');
if (i !== -1) review.splice(i,1);

You were almost there:

You just need to append the li to ul and voila!

So just add

ul.appendChild(li);

to the end of your function so the end function will be like this:

function function1() {
  var ul = document.getElementById("list");
  var li = document.createElement("li");
  li.appendChild(document.createTextNode("Element 4"));
  ul.appendChild(li);
}

All you need to do is make sure that the checkbox shown below is checked.

Here's a sample method that adds two extra columns programmatically to the grid view:

    private void AddColumnsProgrammatically()
    {
        // I created these columns at function scope but if you want to access 
        // easily from other parts of your class, just move them to class scope.
        // E.g. Declare them outside of the function...
        var col3 = new DataGridViewTextBoxColumn();
        var col4 = new DataGridViewCheckBoxColumn();

        col3.HeaderText = "Column3";
        col3.Name = "Column3";

        col4.HeaderText = "Column4";
        col4.Name = "Column4";

        dataGridView1.Columns.AddRange(new DataGridViewColumn[] {col3,col4});
    }

A great way to figure out how to do this kind of process is to create a form, add a grid view control and add some columns. (This process will actually work for ANY kind of form control. All instantiation and initialization happens in the Designer.) Then examine the form's Designer.cs file to see how the construction takes place. (Visual Studio does everything programmatically but hides it in the Form Designer.)

For this example I created two columns for the view named Column1 and Column2 and then searched Form1.Designer.cs for Column1 to see everywhere it was referenced. The following information is what I gleaned and, copied and modified to create two more columns dynamically:

// Note that this info scattered throughout the designer but can easily collected.

        System.Windows.Forms.DataGridViewTextBoxColumn Column1;
        System.Windows.Forms.DataGridViewCheckBoxColumn Column2;

        this.Column1 = new System.Windows.Forms.DataGridViewTextBoxColumn();
        this.Column2 = new System.Windows.Forms.DataGridViewCheckBoxColumn();

        this.dataGridView1.Columns.AddRange(new System.Windows.Forms.DataGridViewColumn[] {
        this.Column1,
        this.Column2});

        this.Column1.HeaderText = "Column1";
        this.Column1.Name = "Column1";

        this.Column2.HeaderText = "Column2";
        this.Column2.Name = "Column2";

2⁹ = 512 values, because that's how many combinations of zeroes and ones you can have.

What those values represent however will depend on the system you are using. If it's an unsigned integer, you will have:

000000000 = 0 (min)
000000001 = 1
...
111111110 = 510
111111111 = 511 (max)

In two's complement, which is commonly used to represent integers in binary, you'll have:

000000000 = 0
000000001 = 1
...
011111110 = 254
011111111 = 255 (max)
100000000 = -256 (min) <- yay integer overflow
100000001 = -255
...
111111110 = -2
111111111 = -1

In general, with k bits you can represent 2^k values. Their range will depend on the system you are using:

Unsigned: 0 to 2^k-1
Signed: -2^k-1 to 2^k-1-1

There are Python libraries that can recognize files based on their content (usually a header / magic number) and that don't rely on the file name or extension.

If you're addressing many different file types, you can use python-magic. That's just a Python binding for the well-established magic library. This has a good reputation and (small endorsement) in the limited use I've made of it, it has been solid.

There are also libraries for more specialized file types. For example, the Python standard library has the imghdr module that does the same thing just for image file types.

If you need dependency-free (pure Python) file type checking, see filetype.

In case you want to move your local git repository to another upstream you can also do this:

to get the current remote url:

git remote get-url origin

will show something like: https://bitbucket.com/git/myrepo

to set new remote repository:

git remote set-url origin [email protected]:folder/myrepo.git

now push contents of current (develop) branch:

git push --set-upstream origin develop

You now have a full copy of the branch in the new remote.

optionally return to original git-remote for this local folder:

git remote set-url origin https://bitbucket.com/git/myrepo

Gives the benefit you can now get your new git-repository from github in another folder so that you have two local folders both pointing to the different remotes, the previous (bitbucket) and the new one both available.

According to the HTML spec, <span> is an inline element and <div> is a block element. Now that can be changed using the display CSS property but there is one issue: in terms of HTML validation, you can't put block elements inside inline elements so:

<p>...<div>foo</div>...</p>

is not strictly valid even if you change the <div> to inline or inline-block.

So, if your element is inline or inline-block use a <span>. If it's a block level element, use a <div>.

This is using the JSONObject(Object) constructor, not the JSONObject(String) one.

Your code should be:

JSONObject jsonObj = new JSONObject(jsonString.toString());

Well your jsonString is wrong.

String jsonString = "{\"stat\":{\"sdr\": \"aa:bb:cc:dd:ee:ff\",\"rcv\": \"aa:bb:cc:dd:ee:ff\",\"time\": \"UTC in millis\",\"type\": 1,\"subt\": 1,\"argv\": [{\"1\":2},{\"2\":3}]}}";

use this jsonString and if you use the same JSONParser and ContainerFactory in the example you will see that it will be encoded/decoded.

Additionally if you want to print your string after stat here it goes:

     try{
        Map json = (Map)parser.parse(jsonString, containerFactory);
        Iterator iter = json.entrySet().iterator();
        System.out.println("==iterate result==");
        Object entry = json.get("stat");
        System.out.println(entry);
      }

And about the json libraries, there are a lot of them. Better you check this.

The scenario in question is better served by each Fragment adding its own menu items and directly handling onOptionsItemSelected(), as described in official documentation. It is better to avoid undocumented tricks.

I needed to measure the execution time of individual functions within a library. I didn't want to have to wrap every call of every function with a time measuring function because its ugly and deepens the call stack. I also didn't want to put timer code at the top and bottom of every function because it makes a mess when the function can exit early or throw exceptions for example. So what I ended up doing was making a timer that uses its own lifetime to measure time.

In this way I can measure the wall-time a block of code took by just instantiating one of these objects at the beginning of the code block in question (function or any scope really) and then allowing the instances destructor to measure the time elapsed since construction when the instance goes out of scope. You can find the full example here but the struct is extremely simple:

template <typename clock_t = std::chrono::steady_clock>
struct scoped_timer {
  using duration_t = typename clock_t::duration;
  const std::function<void(const duration_t&)> callback;
  const std::chrono::time_point<clock_t> start;

  scoped_timer(const std::function<void(const duration_t&)>& finished_callback) :
      callback(finished_callback), start(clock_t::now()) { }
  scoped_timer(std::function<void(const duration_t&)>&& finished_callback) :
      callback(finished_callback), start(clock_t::now()) { }
  ~scoped_timer() { callback(clock_t::now() - start); }
};

The struct will call you back on the provided functor when it goes out of scope so you can do something with the timing information (print it or store it or whatever). If you need to do something even more complex you could even use std::bind with std::placeholders to callback functions with more arguments.

Here's a quick example of using it:

void test(bool should_throw) {
  scoped_timer<> t([](const scoped_timer<>::duration_t& elapsed) {
    auto e = std::chrono::duration_cast<std::chrono::duration<double, std::milli>>(elapsed).count();
    std::cout << "took " << e << "ms" << std::endl;
  });

  std::this_thread::sleep_for(std::chrono::seconds(1));

  if (should_throw)
    throw nullptr;

  std::this_thread::sleep_for(std::chrono::seconds(1));
}

If you want to be more deliberate, you can also use new and delete to explicitly start and stop the timer without relying on scoping to do it for you.

If the image isn't that big, and if there's a good chance you'll be re-using the image often, and if you don't have too many of them, and if the images are not secret (meaning it's no big deal if one user could potentially see another person's image)...

Lots of "if"s here, so there's a good chance this is a bad idea:

You can store the image bytes in Cache for a short time, and make an image tag pointed toward an action method, which in turn reads from the cache and spits out your image. This will allow the browser to cache the image appropriately.

// In your original controller action
HttpContext.Cache.Add("image-" + model.Id, model.ImageBytes, null,
    Cache.NoAbsoluteExpiration, TimeSpan.FromMinutes(1),
    CacheItemPriority.Normal, null);

// In your view:
<img src="@Url.Action("GetImage", "MyControllerName", new{fooId = Model.Id})">

// In your controller:
[OutputCache(VaryByParam = "fooId", Duration = 60)]
public ActionResult GetImage(int fooId) {
    // Make sure you check for null as appropriate, re-pull from DB, etc.
    return File((byte[])HttpContext.Cache["image-" + fooId], "image/gif");
}

This has the added benefit (or is it a crutch?) of working in older browsers, where the inline images don't work in IE7 (or IE8 if larger than 32kB).

Try this:

a = 1
b = 2
int_div  = a // b

SQL Server Reporting Services (SSRS)
SSRS can remain active even if you uninstall SQL Server.
To stop the service:

Open SQL Server Configuration Manager. Select “SQL Server Services” in the left-hand pane. Double-click “SQL Server Reporting Services”. Hit Stop. Switch to the Service tab and set the Start Mode to “Manual”.

Skype
Irritatingly, Skype can switch to port 80. To disable it, select
Tools > Options > Advanced > Connection then uncheck
“Use port 80 and 443 as alternatives for incoming connections”.

IIS (Microsoft Internet Information Server)

For Windows 7 (or vista) its the most likely culprit. You can stop the service from the command line.

Open command line cmd.exe and type:

net stop was /y

For older versions of Windows type:

net stop iisadmin /y

Other

If this does not solve the problem further detective work is necessary if IIS, SSRS and Skype are not to blame. Enter the following on the command line:

netstat -ao

The active TCP addresses and ports will be listed. Locate the line with local address “0.0.0.0:80" and note the PID value. Start Task Manager. Navigate to the Processes tab and, if necessary, click View > Select Columns to ensure “PID (Process Identifier)” is checked. You can now locate the PID you noted above. The description and properties should help you determine which application is using the port.

You can do it with "trick" with invisible iframe. When you set "src" to it, browser reacts as if you would click a link with the same "href". As opposite to solution with form, it enables you to embed additional logic, for example activating download after timeout, when some conditions are met etc.

It is also very silient, there's no blinking new window/tab like when using window.open.

HTML:

<iframe id="invisible" style="display:none;"></iframe>

Javascript:

function download() {
    var iframe = document.getElementById('invisible');
    iframe.src = "file.doc";
}

This code is easier to use:

 View rowView = listView.getChildAt(viewIndex);//The item number in the List View
    if(rowView != null)
        {
           // Your code here
        }

For those using ReactJS.Net and getting this error after a publish:

Check the properties of your .jsx files and make sure Build Action is set to Content. Those set to None will not be published. I came upon this solution from this SO answer.

Normally, the VM would do a garbage collection automatically before throwing an OutOfMemoryException, so adding an explicit call shouldn't help except in that it perhaps moves the performance hit to an earlier moment in time.

However, I think I encountered a case where it might be relevant. I'm not sure though, as I have yet to test whether it has any effect:

When you memory-map a file, I believe the map() call throws an IOException when a large enough block of memory is not available. A garbage collection just before the map() file might help prevent that, I think. What do you think?

Based on @johnny-willer's answer, you cannot get a map with null values on Java 8 because of Collectors.toMap relies on Map.merge. This method does not expect null values, so it throws a NullPointerException as it was described in this bug report: https://bugs.openjdk.java.net/browse/JDK-8148463

An alternative way to get a map with null values using a builder syntax on Java 8 is writing an inline collector:

Map<String, String> myMap = Stream.of(
         new SimpleEntry<>("key1", "value1"),
         new SimpleEntry<>("key2", (String) null),
         new SimpleEntry<>("key3", "value3"))
        .collect(HashMap::new,
                (map, entry) -> map.put(entry.getKey(),
                                        entry.getValue()),
                HashMap::putAll);

Also, this implementation will replace a value if the key appears multiple times. The default Collectors.toMap, without a custom merge function like (prev, next) -> next, will throw an IllegalStatException instead.

If your list contains pure integer strings, the accepted awnswer is the way to go. This solution will crash if you give it things that are not integers.

So: if you have data that may contain ints, possibly floats or other things as well - you can leverage your own function with errorhandling:

def maybeMakeNumber(s):
    """Returns a string 's' into a integer if possible, a float if needed or
    returns it as is."""

    # handle None, "", 0
    if not s:
        return s
    try:
        f = float(s)
        i = int(f)
        return i if f == i else f
    except ValueError:
        return s

data = ["unkind", "data", "42", 98, "47.11", "of mixed", "types"]

converted = list(map(maybeMakeNumber, data))
print(converted)

Output:

['unkind', 'data', 42, 98, 47.11, 'of mixed', 'types']

To also handle iterables inside iterables you can use this helper:

from collections.abc import Iterable, Mapping

def convertEr(iterab):
    """Tries to convert an iterable to list of floats, ints or the original thing
    from the iterable. Converts any iterable (tuple,set, ...) to itself in output.
    Does not work for Mappings  - you would need to check abc.Mapping and handle 
    things like {1:42, "1":84} when converting them - so they come out as is."""

    if isinstance(iterab, str):
        return maybeMakeNumber(iterab)

    if isinstance(iterab, Mapping):
        return iterab

    if isinstance(iterab, Iterable):
        return  iterab.__class__(convertEr(p) for p in iterab)


data = ["unkind", {1: 3,"1":42}, "data", "42", 98, "47.11", "of mixed", 
        ("0", "8", {"15", "things"}, "3.141"), "types"]

converted = convertEr(data)
print(converted)

Output:

['unkind', {1: 3, '1': 42}, 'data', 42, 98, 47.11, 'of mixed', 
 (0, 8, {'things', 15}, 3.141), 'types'] # sets are unordered, hence diffrent order

Double quotes around the filename in the header is the standard per MDN web docs. Omitting the quotes creates multiple opportunities for problems arising from characters in the filename.

Let's understand in simple words

• PRI - It's a primary key, and used to identify records uniquely.
• UNI - It's a unique key, and also used to identify records uniquely. It looks similar like primary key but a table can have multiple unique keys and unique key can have one null value, on the other hand table can have only one primary key and can't store null as a primary key.
• MUL - It's doesn't have unique constraint and table can have multiple MUL columns.

Note: These keys have more depth as a concept but this is good to start.

You're missing the multiplication operator. Also, you want to do 4/3 in floating point, not integer math.

volume = (4.0 / 3) * Math.PI * Math.pow(radius, 3);

On some system, instead of the .bashrc file, you can edit your profils' specific by editing:

sudo nano /etc/profile

You have to create an instance of the Bitmap class, using the constructor overload that loads an image from a file on disk. As your code is written now, you're trying to use the PictureBox.Image property as if it were a method.

Change your code to look like this (also taking advantage of the using statement to ensure proper disposal, rather than manually calling the Dispose method):

private void button1_Click(object sender, EventArgs e)
{
    // Wrap the creation of the OpenFileDialog instance in a using statement,
    // rather than manually calling the Dispose method to ensure proper disposal
    using (OpenFileDialog dlg = new OpenFileDialog())
    {
        dlg.Title = "Open Image";
        dlg.Filter = "bmp files (*.bmp)|*.bmp";

        if (dlg.ShowDialog() == DialogResult.OK)
        {
            PictureBox PictureBox1 = new PictureBox();

            // Create a new Bitmap object from the picture file on disk,
            // and assign that to the PictureBox.Image property
            PictureBox1.Image = new Bitmap(dlg.FileName);
        }
    }
}

Of course, that's not going to display the image anywhere on your form because the picture box control that you've created hasn't been added to the form. You need to add the new picture box control that you've just created to the form's Controls collection using the Add method. Note the line added to the above code here:

private void button1_Click(object sender, EventArgs e)
{
    using (OpenFileDialog dlg = new OpenFileDialog())
    {
        dlg.Title = "Open Image";
        dlg.Filter = "bmp files (*.bmp)|*.bmp";

        if (dlg.ShowDialog() == DialogResult.OK)
        {
            PictureBox PictureBox1 = new PictureBox();
            PictureBox1.Image = new Bitmap(dlg.FileName);

            // Add the new control to its parent's controls collection
            this.Controls.Add(PictureBox1);
        }
    }
}

You can use sshpass for it. Below are the steps

1. Install sshpass For Ubuntu - sudo apt-get install sshpass
2. Add the Remote IP to your known-host file if it is first time For Ubuntu -> ssh user@IP -> enter 'yes'
3. give a combined command of scp and sshpass for it. Below is a sample code for war coping to remote tomcat sshpass -p '#Password_For_remote_machine' scp /home/ubuntu/latest_build/abc.war #user@#RemoteIP:/var/lib/tomcat7/webapps

You can also try this

// create a thread  
Thread newWindowThread = new Thread(new ThreadStart(() =>  
{  
    // create and show the window
    FaxImageLoad obj = new FaxImageLoad(destination);  
    obj.Show();  
    
    // start the Dispatcher processing  
    System.Windows.Threading.Dispatcher.Run();  
}));  

// set the apartment state  
newWindowThread.SetApartmentState(ApartmentState.STA);  

// make the thread a background thread  
newWindowThread.IsBackground = true;  

// start the thread  
newWindowThread.Start();  

Let consider that your data are in the file values.txt and that you want to import them in the database table myTable then the following query does the job

COPY myTable FROM 'value.txt' (DELIMITER('|'));
