Somehow postman didn't work for me. I had to use a chrome extension called RESTED which did work.

You could always switch out the first and third examples with a while loop and a little more code. This gives you the advantage of being able to use the do-while:

int i = 0;
do{
 E element = list.get(i);
 i++;
}
while (i < list.size());

Of course, this kind of thing might cause a NullPointerException if the list.size() returns 0, becuase it always gets executed at least once. This can be fixed by testing if element is null before using its attributes / methods tho. Still, it's a lot simpler and easier to use the for loop

"Atomic operation" means an operation that appears to be instantaneous from the perspective of all other threads. You don't need to worry about a partly complete operation when the guarantee applies.

That is, you are referencing an image, but instead of providing an external url, the png image data is in the url itself, embedded in the style sheet. data:image/png;base64 tells the browser that the data is inline, is a png image and is in this case base64 encoded. The encoding is needed because png images can contain bytes that are invalid inside a HTML document (or within the HTTP protocol even).

Just FYI, if you are using Java 11+, there is an exception to this rule: if you run your java file directly (without compilation). In this mode, there is no restriction on a single public class per file. However, the class with the main method must be the first one in the file.

I'm assuming you have an IEnumerable, and in your example delegate, you would like c1 and c2 to be referring to two elements in this list?

I believe you could achieve this with a self join var distinctResults = from c1 in myList join c2 in myList on

you may want it to be ==, but 123.4444444444443 != 123.4444444444442

just simply (PowerShell V5)

Get-ChildItem "C:\temp" -Recurse -File | Where CreationTime -lt  (Get-Date).AddDays(-15)  | Remove-Item -Force

I think it has to do with your second element in storbinary. You are trying to open file, but it is already a pointer to the file you opened in line file = open(local_path,'rb'). So, try to use ftp.storbinary("STOR " + i, file).

In order to ensure there is no compilation error, place the file on your classpath when compiling (-cp command-line option, or check your IDE documentation).

After testing most of the switches this worked for me:

xcopy C:\folder1 C:\folder2\folder1 /t /e /i /y

This will copy the folder folder1 into the folder folder2. So the directory tree would look like:

C:
   Folder1
   Folder2
      Folder1

You could:

SELECT COALESCE(SUM(columnA), 0) FROM my_table WHERE columnB = 1
INTO res;

This happens to work, because your query has an aggregate function and consequently always returns a row, even if nothing is found in the underlying table.

Plain queries without aggregate would return no row in such a case. COALESCE would never be called and couldn't save you. While dealing with a single column we can wrap the whole query instead:

SELECT COALESCE( (SELECT columnA FROM my_table WHERE ID = 1), 0)
INTO res;

Works for your original query as well:

SELECT COALESCE( (SELECT SUM(columnA) FROM my_table WHERE columnB = 1), 0)
INTO res;

If you plan to use setTextAppearance you should know that it will overwrite the text color with the style inherited from the theme. So if you want to use both, set the color afterwards.

This works:

textView.setTextAppearance(context, android.R.style.TextAppearance_Medium);
textView.setTextColor(Color.RED);

While this will cause your textcolor to be for instance white(for dark theme) or black(for the light theme):

textView.setTextColor(Color.RED);
textView.setTextAppearance(context, android.R.style.TextAppearance_Medium);

Contrary to this in XML the order is arbitrary.

Its really helpful. The only problem i had was the size of sound file created after recording. I needed to reduce the file size so i did some changes in settings.

NSMutableDictionary *recordSetting = [[NSMutableDictionary alloc] init];
[recordSetting setValue :[NSNumber numberWithInt:kAudioFormatAppleIMA4] forKey:AVFormatIDKey];
[recordSetting setValue:[NSNumber numberWithFloat:16000.0] forKey:AVSampleRateKey];
[recordSetting setValue:[NSNumber numberWithInt: 1] forKey:AVNumberOfChannelsKey];

File size reduced from 360kb to just 25kb (2 seconds recording).

The Set statement is only used for object variables (like Range, Cell or Worksheet in Excel), while the simple equal sign '=' is used for elementary datatypes like Integer. You can find a good explanation for when to use set here.

The other problem is, that your variable g1val isn't actually declared as Integer, but has the type Variant. This is because the Dim statement doesn't work the way you would expect it, here (see example below). The variable has to be followed by its type right away, otherwise its type will default to Variant. You can only shorten your Dim statement this way:

Dim intColumn As Integer, intRow As Integer  'This creates two integers

For this reason, you will see the "Empty" instead of the expected "0" in the Watches window.

Try this example to understand the difference:

Sub Dimming()

  Dim thisBecomesVariant, thisIsAnInteger As Integer
  Dim integerOne As Integer, integerTwo As Integer

  MsgBox TypeName(thisBecomesVariant)  'Will display "Empty"
  MsgBox TypeName(thisIsAnInteger )  'Will display "Integer"
  MsgBox TypeName(integerOne )  'Will display "Integer"
  MsgBox TypeName(integerTwo )  'Will display "Integer"

  'By assigning an Integer value to a Variant it becomes Integer, too
  thisBecomesVariant = 0
  MsgBox TypeName(thisBecomesVariant)  'Will display "Integer"

End Sub

Two further notices on your code:

First remark: Instead of writing

'If g1val is bigger than the value in the current cell
If g1val > Cells(33, i).Value Then
  g1val = g1val   'Don't change g1val
Else
  g1val = Cells(33, i).Value  'Otherwise set g1val to the cell's value
End If

you could simply write

'If g1val is smaller or equal than the value in the current cell
If g1val <= Cells(33, i).Value Then
  g1val = Cells(33, i).Value  'Set g1val to the cell's value 
End If

Since you don't want to change g1val in the other case.

Second remark: I encourage you to use Option Explicit when programming, to prevent typos in your program. You will then have to declare all variables and the compiler will give you a warning if a variable is unknown.

I have got the same problem on Xamarin.Android - VS (2017)

The Solution that worked for me:

SOLUTION

In your XML file add:

 xmlns:card_view="http://schemas.android.com/apk/res-auto"

and in your android.support.v7.widget.CardView element add this propriety:

card_view:cardBackgroundColor="#ffb4b4"

(i.e.)

<android.support.v7.widget.CardView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal"
    android:layout_margin="12dp"
    card_view:cardCornerRadius="4dp"
    card_view:cardElevation="1dp"
    card_view:cardPreventCornerOverlap="false"
    card_view:cardBackgroundColor="#ffb4b4" />

You can also add cardElevation and cardElevation.

If you want to edit the cardview programmatically you just need to use this code: For (C#)

    cvBianca = FindViewById<Android.Support.V7.Widget.CardView>(Resource.Id.cv_bianca);
    cvBianca.Elevation = 14;
    cvBianca.Radius = 14;
    cvBianca.PreventCornerOverlap = true;
    cvBianca.SetCardBackgroundColor(Color.Red);

And now you can change background color programmatically without lost border, corner radius and elevation.

The following worked for me:

Put your curl statement in a script named abc.sh

Now run:

sh abc.sh 1>stdout_output 2>stderr_output

You will get your curl's results in stdout_output and the progress info in stderr_output.

This work for me:

 $('#data_compra').daterangepicker({
          singleDatePicker: true,
          locale: {
           format: 'DD/MM/YYYY'
          },
         calender_style: "picker_4", }, 
function(start, end, label) {
          console.log(start.toISOString(), end.toISOString(), label); 
});

In answer ,it creates circular dependency.This can be avoided by removing parent inside Child nodes. i.e,

public class MyTreeNode<T>{     


    private T data = null;
    private List<MyTreeNode> children = new ArrayList<>();


    public MyTreeNode(T data) {
        this.data = data;

    }

    public void addChild(MyTreeNode child) {
        this.children.add(child);
    }

    public void addChild(T data) {
        MyTreeNode<T> newChild = new MyTreeNode<>(data);
        children.add(newChild);
    }

    public void addChildren(List<MyTreeNode> children) {
        this.children.addAll(children);
    }

    public List<MyTreeNode> getChildren() {
        return children;
    }

    public T getData() {
        return data;
    }

    public void setData(T data) {
        this.data = data;
    }


}

Using the same example specified above,the output will be like this:

{ "data": "Root", "children": [ { "data": "Child1", "children": [ { "data": "Grandchild1", "children": [] }, { "data": "Grandchild2", "children": [] } ] }, { "data": "Child2", "children": [ { "data": "Grandchild3", "children": [] } ] }, { "data": "Child3", "children": [] }, { "data": "Child4", "children": [] }, { "data": "Child5", "children": [] }, { "data": "Child6", "children": [] } ] }

1. use sys.argv to get the command-line parameters
2. use open(), read() to manipulate file
3. use the Python re module to match lines

To navigate to another component you can use this.props.history.push('/main');

import React, { Component, Fragment } from 'react'

class Example extends Component {

  redirect() {
    this.props.history.push('/main')
  }

  render() {
    return (
      <Fragment>
        {this.redirect()}
      </Fragment>
    );
   }
 }

 export default Example

Use can use CSS too, add focus and active (for IE7 and under) to the hidden link. Example of a ul menu inside a div with class menu:

.menu ul ul {display:none; position:absolute; left:100%; top:0; padding:0;}
.menu ul ul ul {display:none; position:absolute; top:0; left:100%;}
.menu ul ul a, .menu ul ul a:focus, .menu ul ul a:active { width:170px; padding:4px 4%; background:#e77776; color:#fff; margin-left:-15px; }
.menu ul li:hover > ul { display:block; }
.menu ul li ul li {margin:0;}

It's late and untested, should work ;-)

Vertical align doesn't quite work the way you want it to. See: http://phrogz.net/css/vertical-align/index.html

This isn't pretty, but it WILL do what you want: Vertical align behaves as expected only when used in a table cell.

http://jsfiddle.net/e8ESb/6/

There are other alternatives: You can declare things as tables or table cells within CSS to make them behave as desired, for example. Margins and positioning can sometimes be played with to get the same effect. None of the solutions are terrible pretty, though.

Attach an event listener to the form using .addEventListener() and then call the .preventDefault() method on event:

const element = document.querySelector('form');_x000D_
element.addEventListener('submit', event => {_x000D_
  event.preventDefault();_x000D_
  // actual logic, e.g. validate the form_x000D_
  console.log('Form submission cancelled.');_x000D_
});

<form>_x000D_
  <button type="submit">Submit</button>_x000D_
</form>

I think it's a better solution than defining a submit event handler inline with the onsubmit attribute because it separates webpage logic and structure. It's much easier to maintain a project where logic is separated from HTML. See: Unobtrusive JavaScript.

Using the .onsubmit property of the form DOM object is not a good idea because it prevents you from attaching multiple submit callbacks to one element. See addEventListener vs onclick .

If you are in IE11, you can tell IE to always refresh from the server for a specific browsing session with IE Developer Tools.

• Open IE Developer Tools with F12 key
• Go to Network tab
• Click on button "always refresh from the server"

(Sorry for french capture)

I change my monitor DPI settings from the launch options of AVD and synchronized it with the original and current setting of my monitor, and it worked.

Suppose a 9800GT GPU:

• it has 14 multiprocessors (SM)
• each SM has 8 thread-processors (AKA stream-processors, SP or cores)
• allows up to 512 threads per block
• warpsize is 32 (which means each of the 14x8=112 thread-processors can schedule up to 32 threads)

https://www.tutorialspoint.com/cuda/cuda_threads.htm

A block cannot have more active threads than 512 therefore __syncthreads can only synchronize limited number of threads. i.e. If you execute the following with 600 threads:

func1();
__syncthreads();
func2();
__syncthreads();

then the kernel must run twice and the order of execution will be:

1. func1 is executed for the first 512 threads
2. func2 is executed for the first 512 threads
3. func1 is executed for the remaining threads
4. func2 is executed for the remaining threads

Note:

The main point is __syncthreads is a block-wide operation and it does not synchronize all threads.

I'm not sure about the exact number of threads that __syncthreads can synchronize, since you can create a block with more than 512 threads and let the warp handle the scheduling. To my understanding it's more accurate to say: func1 is executed at least for the first 512 threads.

Before I edited this answer (back in 2010) I measured 14x8x32 threads were synchronized using __syncthreads.

I would greatly appreciate if someone test this again for a more accurate piece of information.

To give Network Service read permission on the EventLog/Security key (as suggested by Firenzi and royrules22) follow instructions from http://geekswithblogs.net/timh/archive/2005/10/05/56029.aspx

1. Open the Registry Editor:
   1. Select Start then Run
   2. Enter regedt32 or regedit

2. Navigate/expand to the following key:

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Security

3. Right click on this entry and select Permissions

4. Add the Network Service user

5. Give it Read permission

UPDATE: The steps above are ok on developer machines, where you do not use deployment process to install application.
However if you deploy your application to other machine(s), consider to register event log sources during installation as suggested in SailAvid's and Nicole Calinoiu's answers.

I am using PowerShell function (calling in Octopus Deploy.ps1)

function Create-EventSources() {
    $eventSources = @("MySource1","MySource2" )
    foreach ($source in $eventSources) {
            if ([System.Diagnostics.EventLog]::SourceExists($source) -eq $false) {
                [System.Diagnostics.EventLog]::CreateEventSource($source, "Application")
            }
    }
}

As far as I know, basic animates can't animate non-numeric CSS properties.

I believe you could get this done using a step function and the appropriate css3 transform for the users browser. CSS3 transform is a bit tricky to cover all your browsers in (IE6 you need to use the Matrix filter, for instance).

EDIT: here's an example that works in webkit browsers (Chrome, Safari): http://jsfiddle.net/ryleyb/ERRmd/

If you wanted to support IE9 only, you could use transform instead of -webkit-transform, or -moz-transform would support FireFox.

The trick used is to animate a CSS property we don't care about (text-indent) and then use its value in a step function to do the rotation:

$('#foo').animate(
..
step: function(now,fx) {
  $(this).css('-webkit-transform','rotate('+now+'deg)'); 
}
...

Typically you would accomplish this using an ajax request that looks like

var xhr = new XMLHttpRequest();
xhr.open("GET", "pythoncode.py?text=" + text, true);
xhr.responseType = "JSON";
xhr.onload = function(e) {
  var arrOfStrings = JSON.parse(xhr.response);
}
xhr.send();

Here dataTpe is "json" so, data/reqParam must be in the form of string while calling API, many as much as object as you want but at last inside $.ajax's data stringify the object.

             let person= {  name: 'john',
                age: 22
            };

           var personStr = JSON.stringify(person); 

            $.ajax({
                url: "@Url.Action("METHOD", "CONTROLLER")",
                type: "POST",
                data: JSON.stringify( { param1: personStr } ),
                contentType: "application/json;charset=utf-8",
                dataType: "json",
        success: function (response) {

            console.log("Success");

        },
        error: function (error) {
            console.log("error found",error);
        }
    });

OR,

       $.ajax({
                url: "@Url.Action("METHOD", "CONTROLLER")",
                type: "POST",
                data: personStr,
                contentType: "application/json;charset=utf-8",
                dataType: "json",
        success: function (response) {

            console.log("Success");

        },
        error: function (error) {
            console.log("error found",error);
        }
    });

<androidx.constraintlayout.widget.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    //more views

</androidx.constraintlayout.widget.ConstraintLayout>

In the above code, the basic need of tools:context is to tell which activity or fragment the layout file is associated with by default. So, you can specify the activity class name using the same dot prefix as used in Manifest file.

By doing so, the Android Studio will choose the necessary theme for the preview automatically and you don’t have to do the preview settings manually. As we all know that a layout file can be associated with several activities but the themes are defined in the Manifest file and these themes are associated with your activity. So, by adding tools:context in your layout file, the Android Studio preview will automatically choose the necessary theme for you.

I found the answer I was looking for. The thing to use here is the construct of

\left \middle \right

For example, in this case, two possible solutions are:

$\left( {\frac{a_1}{a_2}} \middle/ {\frac{b_1}{b_2}} \right) $

Or, in case the brackets are not necessary:

$\left. {\frac{a_1}{a_2}} \middle/ {\frac{b_1}{b_2}} \right. $

See this link text view android:password

This applies for EditText as well, as it is a known direct subclass of TextView.

Here is another apporach.

You can accomplish it in this way too:

.parent{
  display: flex;
  flex-wrap: wrap;
}

.child{
  width: 25%;
  box-sizing: border-box;
}

And a more complete sample: https://codepen.io/capynet/pen/JyYaba

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

ObjectOutputStream

Step-by-Step way to do this:

1. Install Android SDK
2. Start the emulator by going to $SDK_root/emulator.exe
3. Go to command prompt and go to the directory $SDK_root/platform-tools (or else add the path to windows environment)
4. Type in the command adb install
5. Bingo. Your app should be up and running on the emulator

1) sys.path is a list.

2) The problem is sometimes the sys.path is not your virtualenv.path and you want to use pylint in your virtualenv

3) So like said, use init-hook (pay attention in ' and " the parse of pylint is strict)

[Master]
init-hook='sys.path = ["/path/myapps/bin/", "/path/to/myapps/lib/python3.3/site-packages/", ... many paths here])'

or

[Master]
init-hook='sys.path = list(); sys.path.append("/path/to/foo")'

.. and

pylint --rcfile /path/to/pylintrc /path/to/module.py

The consensus here is to put the global variables in a static class as static members. When you create a new Windows Forms application, it usually comes with a Program class (Program.cs), which is a static class and serves as the main entry point of the application. It lives for the the whole lifetime of the app, so I think it is best to put the global variables there instead of creating a new one.

static class Program
{
    public static string globalString = "This is a global string.";

    /// <summary>
    /// The main entry point for the application.
    /// </summary>
    [STAThread]
    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new Form1());
    }
}

And use it as such:

public partial class Form1 : Form
{
    public Form1()
    {
        Program.globalString = "Accessible in Form1.";

        InitializeComponent();
    }
}

Install PIL(Python Image Library) :

then:

from PIL import Image
myImage = Image.open("your_image_here");
myImage.show();

The maketrans and translate methods of str are handy for this type of thing.

Here's a general solution:

import string

def make_rot_n(n):
    lc = string.ascii_lowercase
    uc = string.ascii_uppercase
    trans = str.maketrans(lc + uc,
                          lc[n:] + lc[:n] + uc[n:] + uc[:n])
    return lambda s: str.translate(s, trans)

rot13 = make_rot_n(13)

rot13('foobar')
# 'sbbone'

My solution is:

const urlSplit = this._router.url.split('/');
this._router.navigate([urlSplit.splice(0, urlSplit.length - 1).join('/')], { relativeTo: this._route.parent });

And the Router injection:

private readonly _router: Router

I am always used DateDiff(day,date1,date2) to compare two date.

Checkout following example. Just copy that and run in Ms sql server. Also, try with change date by 31 dec to 30 dec and check result

BEGIN

declare @firstDate datetime
declare @secondDate datetime


declare @chkDay int

set @firstDate ='2010-12-31 15:13:48.593'
set @secondDate ='2010-12-31 00:00:00.000'

set @chkDay=Datediff(day,@firstDate ,@secondDate )

if @chkDay=0
    Begin
        Print 'Date is Same'
    end
else
    Begin
        Print 'Date is not Same'
    end
End

My full example is here, but I will provide a summary below.

Layout

Add a .swift and .xib file each with the same name to your project. The .xib file contains your custom view layout (using auto layout constraints preferably).

Make the swift file the xib file's owner.

Code

Add the following code to the .swift file and hook up the outlets and actions from the .xib file.

import UIKit
class ResuableCustomView: UIView {

    let nibName = "ReusableCustomView"
    var contentView: UIView?

    @IBOutlet weak var label: UILabel!
    @IBAction func buttonTap(_ sender: UIButton) {
        label.text = "Hi"
    }

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)

        guard let view = loadViewFromNib() else { return }
        view.frame = self.bounds
        self.addSubview(view)
        contentView = view
    }

    func loadViewFromNib() -> UIView? {
        let bundle = Bundle(for: type(of: self))
        let nib = UINib(nibName: nibName, bundle: bundle)
        return nib.instantiate(withOwner: self, options: nil).first as? UIView
    }
}

Use it

Use your custom view anywhere in your storyboard. Just add a UIView and set the class name to your custom class name.

For a while Christopher Swasey's approach was the best approach I had found. I asked a couple of the senior devs on my team about it and one of them had the perfect solution! It satisfies every one of the concerns that Christopher Swasey so eloquently addressed and it doesn't require boilerplate subclass code(my main concern with his approach). There is one gotcha, but other than that it is fairly intuitive and easy to implement.

1. Create a custom UIView class in a .swift file to control your xib. i.e. MyCustomClass.swift
2. Create a .xib file and style it as you want. i.e. MyCustomClass.xib
3. Set the File's Owner of the .xib file to be your custom class (MyCustomClass)
4. GOTCHA: leave the class value (under the identity Inspector) for your custom view in the .xib file blank. So your custom view will have no specified class, but it will have a specified File's Owner.
5. Hook up your outlets as you normally would using the Assistant Editor.
   • NOTE: If you look at the Connections Inspector you will notice that your Referencing Outlets do not reference your custom class (i.e. MyCustomClass), but rather reference File's Owner. Since File's Owner is specified to be your custom class, the outlets will hook up and work propery.
6. Make sure your custom class has @IBDesignable before the class statement.
7. Make your custom class conform to the NibLoadable protocol referenced below.
   • NOTE: If your custom class .swift file name is different from your .xib file name, then set the nibName property to be the name of your .xib file.
8. Implement required init?(coder aDecoder: NSCoder) and override init(frame: CGRect) to call setupFromNib() like the example below.
9. Add a UIView to your desired storyboard and set the class to be your custom class name (i.e. MyCustomClass).
10. Watch IBDesignable in action as it draws your .xib in the storyboard with all of it's awe and wonder.

Here is the protocol you will want to reference:

public protocol NibLoadable {
    static var nibName: String { get }
}

public extension NibLoadable where Self: UIView {

    public static var nibName: String {
        return String(describing: Self.self) // defaults to the name of the class implementing this protocol.
    }

    public static var nib: UINib {
        let bundle = Bundle(for: Self.self)
        return UINib(nibName: Self.nibName, bundle: bundle)
    }

    func setupFromNib() {
        guard let view = Self.nib.instantiate(withOwner: self, options: nil).first as? UIView else { fatalError("Error loading \(self) from nib") }
        addSubview(view)
        view.translatesAutoresizingMaskIntoConstraints = false
        view.leadingAnchor.constraint(equalTo: self.safeAreaLayoutGuide.leadingAnchor, constant: 0).isActive = true
        view.topAnchor.constraint(equalTo: self.safeAreaLayoutGuide.topAnchor, constant: 0).isActive = true
        view.trailingAnchor.constraint(equalTo: self.safeAreaLayoutGuide.trailingAnchor, constant: 0).isActive = true
        view.bottomAnchor.constraint(equalTo: self.safeAreaLayoutGuide.bottomAnchor, constant: 0).isActive = true
    }
}

And here is an example of MyCustomClass that implements the protocol (with the .xib file being named MyCustomClass.xib):

@IBDesignable
class MyCustomClass: UIView, NibLoadable {

    @IBOutlet weak var myLabel: UILabel!

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        setupFromNib()
    }

    override init(frame: CGRect) {
        super.init(frame: frame)
        setupFromNib()
    }

}

NOTE: If you miss the Gotcha and set the class value inside your .xib file to be your custom class, then it will not draw in the storyboard and you will get a EXC_BAD_ACCESS error when you run the app because it gets stuck in an infinite loop of trying to initialize the class from the nib using the init?(coder aDecoder: NSCoder) method which then calls Self.nib.instantiate and calls the init again.

C++ provides a good mechanism to manage the life time of an object though class/struct constructs. This is one of the best features of C++ over other languages.

When you have member variables exposed through ref or pointer it violates the encapsulation in principle. This idiom enables the consumer of the class to change the state of an object of A without it(A) having any knowledge or control of it. It also enables the consumer to hold on to a ref/pointer to A's internal state, beyond the life time of the object of A. This is bad design. Instead the class could be refactored to hold a ref/pointer to the shared object (not own it) and these could be set using the constructor (Mandate the life time rules). The shared object's class may be designed to support multithreading/concurrency as the case may apply.

Try vterm, which is a pretty much full feature shell inside vim. It is slightly buggy with its history and clear functions, and still in development, but it still is pretty good

SharePoint lists V: Techniques for managing large lists :

Tutorial By Microsoft

Level: Advanced

Length: 40 - 50 minutes

When a SharePoint list gets large, you might see warnings such as, “This list exceeds the list view threshold,” or “Displaying the newest results below.” Find out why these warnings occur, and learn ways to configure your large list so that it still provides useful information.

After completing this course you will be able to:

• Learn what the List View Threshold is, and understand its benefits.
• Create an index so that you can see more information in a view.
• Create folders to better organize your large list.
• Use Datasheet view for fast filtering and sorting of a large list.
• Learn what the Daily Time Window for Large Queries is.
• Use Key Filters for fast filtering within Standard view.
• Sync a large list to SharePoint Workspace.
• Export a large list to Excel. Link a large list in Access.

For the question

How can i run a jar file in command prompt but with arguments

.

To pass arguments to the jar file at the time of execution

java -jar myjar.jar arg1 arg2

In the main() method of "Main-Class" [mentioned in the manifest.mft file]of your JAR file. you can retrieve them like this:

String arg1 = args[0];
String arg2 = args[1];

I have Used Following Methods But non of them worked:

   // 2 Method Failed

        $.get(
            'http://www.corsproxy.com/' +

  })
  .fail(function() {

What worked For me to simply download chrome extension called "200 OK!" or Web server for chrome and write my code like this:

// Worked After local Web Server

        $(document).ready(function () {
            $.getJSON('./json/movies-coming-soon.json', function (data) {
              var movie_name = '';
              var movie_year = '';
                $.each(data,function(i,item){
                    console.log(item.title,item.year,item.poster)
                    movie_name += item.title + "  " + item.year + "<br> <br>"

                    $('#movie_name').html(movie_name)


                })

            })

        })

Its because you can not access local file without running local web server as per CORS policy so in order to running it you must have some host server.

If you need to convert the dictionary to binary, you need to convert it to a string (JSON) as described in the previous answer, then you can convert it to binary.

For example:

my_dict = {'key' : [1,2,3]}

import json
def dict_to_binary(the_dict):
    str = json.dumps(the_dict)
    binary = ' '.join(format(ord(letter), 'b') for letter in str)
    return binary


def binary_to_dict(the_binary):
    jsn = ''.join(chr(int(x, 2)) for x in the_binary.split())
    d = json.loads(jsn)  
    return d

bin = dict_to_binary(my_dict)
print bin

dct = binary_to_dict(bin)
print dct

will give the output

1111011 100010 1101011 100010 111010 100000 1011011 110001 101100 100000 110010 101100 100000 110011 1011101 1111101

{u'key': [1, 2, 3]}

This approach using git-remote worked well for me for HTTPS remotes:

$ git remote -v | grep "(fetch)" | sed 's/.*\/\([^ ]*\)\/.*/\1/'
                                                |  |        | |
                                                |  |        | +---------------+
                                                |  |        | Extract capture |
                                                |  +--------------------+-----+
                                                |Repository name capture|
                                                +-----------------------+

Example

A javascript fix to apply the 'active' class to all labels that are parents of checked inputs:

$(':input:checked').parent('.btn').addClass('active');

insert right after

$('.btn').button();

What worked for me on Windows:

1. Downloaded command line tools from https://developer.android.com/studio/index.html
2. Put the whole tools folder from the ZIP archive to C:\Program Files (x86)\Android SDK\
3. Launched tools\android.bat as administrator, which opened the usual SDK Manager window
4. Installed required components. The files were downloaded to ...\Android SDK\ directory (that is build-tools, platforms, platform-tools, etc. directories appeared alongside tools inside ...\Android SDK\)
5. Opened the Android project in Intellij IDEA, navigated to File->Project Structure->SDKs, and added Android SDK by directing to ...\Android SDK\ directory

You don't have to include String twice, and you don't have to use New.
Either of the following will work...

Dim strings() as String = {}
Dim strings as String() = {}

Alt + Right Arrow and Alt + Numpad 6 (if Num Lock is disabled) are also possibilities.

This worked for me,

1. For getting Columns having at least 1 null value. (column names)

data.columns[data.isnull().any()]

2. For getting Columns with count, with having at least 1 null value.

data[data.columns[data.isnull().any()]].isnull().sum()

[Optional] 3. For getting percentage of the null count.

data[data.columns[data.isnull().any()]].isnull().sum() * 100 / data.shape[0]

Apart from price and features, the throughput also varies greatly (as mentioned by user1677120):

EBS

Taken from EBS docs:

| EBS volume | Throughput |           Throughput          |
|    type    |   MiB/s    |         dependent on..        |
|------------|------------|-------------------------------|
| gp2 (SSD)  | 128-160    | volume size                   |
| io1 (SSD)  | 0.25-500   | IOPS (256Kib/s per IOPS)      |
| st1 (HDD)  | 20-500     | volume size (40Mib/s per TiB) |
| sc1 (HDD)  | 6-250      | volume size (12Mib/s per TiB) |

Note, that for io1, st1 and sc1 you can burst throughput traffic to at least 125Mib/s, but to 500Mib/s, depending on volume size.

You can further increase throughput by e.g. deploying EBS volumes as RAID0

EFS

Taken from EFS docs

| Filesystem |    Base    |   Burst    |
|    Size    | Throughput | Throughput |
|    GiB     |   MiB/s    |   MiB/s    |
|------------|------------|------------|
|         10 |        0.5 |        100 |
|        256 |       12.5 |        100 |
|        512 |       25.0 |        100 |
|       1024 |       50.0 |        100 |
|       1536 |       75.0 |        150 |
|       2048 |      100.0 |        200 |
|       3072 |      150.0 |        300 |
|       4096 |      200.0 |        400 |

The base throughput is guaranteed, burst throughput uses up credits you gathered while being below the base throughput (so you'll only have this for a limited time, see here for more details.

S3

S3 is a total different thing, so it cannot really be compared to EBS and EFS. Plus: There are no published throughput metrics for S3. You can improve throughput by downloading in parallel (I somewhere read AWS states you would have basically unlimited throughput this way), or adding CloudFront to the mix

gcc has become a widely used compiler. Its optimizations in general are not that good. Far better than the average programmer writing assembler, but for real performance, not that good. There are compilers that are simply incredible in the code they produce. So as a general answer there are going to be many places where you can go into the output of the compiler and tweak the assembler for performance, and/or simply re-write the routine from scratch.

Just finished writing my own parser. I tried to use various parser found here, none seems to work with both ksh93 (AIX) and bash (Linux).

It's old programming style - parsing line by line. Pretty fast since it used few external commands. A bit slower because of all the eval required for dynamic name of the array.

The ini support 3 special syntaxs:

• includefile=ini file --> Load an additionnal ini file. Useful for splitting ini in multiple files, or re-use some piece of configuration
• includedir=directory --> Same as includefile, but include a complete directory
• includesection=section --> Copy an existing section to the current section.

I used all thoses syntax to have pretty complex, re-usable ini file. Useful to install products when installing a new OS - we do that a lot.

Values can be accessed with ${ini[$section.$item]}. The array MUST be defined before calling this.

Have fun. Hope it's useful for someone else!

Take a look at the Event Log API. Case a) (bluescreen, user cut the power cord or system hang) causes a note ('system did not shutdown correctly' or something like that) to be left in the 'System' event log the next time the system is rebooted properly. You should be able to access it programmatically using the above API (honestly, I've never used it but it should work).

Did you try a UNC share?

\\server\share\foo.exe

Make sure that both projects are in the same .net version also check copy local property but this should be true as default

This is a very big problem. What actually happens in your code is this:

• You load Parent from the database and get an attached entity
• You replace its child collection with new collection of detached children
• You save changes but during this operation all children are considered as added becasue EF didn't know about them till this time. So EF tries to set null to foreign key of old children and insert all new children => duplicate rows.

Now the solution really depends on what you want to do and how would you like to do it?

If you are using ASP.NET MVC you can try to use UpdateModel or TryUpdateModel.

If you want just update existing children manually, you can simply do something like:

foreach (var child in modifiedParent.ChildItems)
{
    context.Childs.Attach(child); 
    context.Entry(child).State = EntityState.Modified;
}

context.SaveChanges();

Attaching is actually not needed (setting the state to Modified will also attach the entity) but I like it because it makes the process more obvious.

If you want to modify existing, delete existing and insert new childs you must do something like:

var parent = context.Parents.GetById(1); // Make sure that childs are loaded as well
foreach(var child in modifiedParent.ChildItems)
{
    var attachedChild = FindChild(parent, child.Id);
    if (attachedChild != null)
    {
        // Existing child - apply new values
        context.Entry(attachedChild).CurrentValues.SetValues(child);
    }
    else
    {
        // New child
        // Don't insert original object. It will attach whole detached graph
        parent.ChildItems.Add(child.Clone());
    }
}

// Now you must delete all entities present in parent.ChildItems but missing
// in modifiedParent.ChildItems
// ToList should make copy of the collection because we can't modify collection
// iterated by foreach
foreach(var child in parent.ChildItems.ToList())
{
    var detachedChild = FindChild(modifiedParent, child.Id);
    if (detachedChild == null)
    {
        parent.ChildItems.Remove(child);
        context.Childs.Remove(child); 
    }
}

context.SaveChanges();

I'm using spring-boot-1.3.5.RELEASE and I had the same issue. None of above solutions are not worked for me. But finally adding following property to application.properties was fixed the problem.

• OPTIONS Identifying which HTTP methods a resource supports, e.g. can we DELETE it or update it via a PUT?
• HEAD Checking whether a resource has changed. This is useful when maintaining a cached version of a resource
• HEAD Retrieving metadata about the resource, e.g. its media type or its size, before making a possibly costly retrieval
• HEAD, OPTIONS Testing whether a resource exists and is accessible. For example, validating user-submitted links in an application

Here is nice and concise article about how HEAD and OPTIONS fit into RESTful architecture.

Deletion of a topic has been supported since 0.8.2.x version. You have to enable topic deletion (setting delete.topic.enable to true) on all brokers first.

Note: Ever since 1.0.x, the functionality being stable, delete.topic.enable is by default true.

Follow this step by step process for manual deletion of topics

1. Stop Kafka server
2. Delete the topic directory, on each broker (as defined in the logs.dirs and log.dir properties) with rm -rf command
3. Connect to Zookeeper instance: zookeeper-shell.sh host:port
4. From within the Zookeeper instance:
   1. List the topics using: ls /brokers/topics
   2. Remove the topic folder from ZooKeeper using: rmr /brokers/topics/yourtopic
   3. Exit the Zookeeper instance (Ctrl+C)
5. Restart Kafka server
6. Confirm if it was deleted or not by using this command kafka-topics.sh --list --zookeeper host:port

Add bottom:100% to your #menu:hover ul li:hover ul rule

Demo 1

#menu:hover ul li:hover ul {
    position: absolute;
    margin-top: 1px;
    font: 10px;
    bottom: 100%; /* added this attribute */
}

Or better yet to prevent the submenus from having the same effect, just add this rule

Demo 2

#menu>ul>li:hover>ul { 
    bottom:100%;
}

Demo 3

source: http://jsfiddle.net/W5FWW/4/

And to get back the border you can add the following attribute

#menu>ul>li:hover>ul { 
    bottom:100%;
    border-bottom: 1px solid transparent
}

Up until recently my answer would have been very close to Jon Skeet's here. However, I recently started a project which used power-of-two hash tables, that is hash tables where the size of the internal table is 8, 16, 32, etc. There's a good reason for favouring prime-number sizes, but there are some advantages to power-of-two sizes too.

And it pretty much sucked. So after a bit of experimentation and research I started re-hashing my hashes with the following:

public static int ReHash(int source)
{
  unchecked
  {
    ulong c = 0xDEADBEEFDEADBEEF + (ulong)source;
    ulong d = 0xE2ADBEEFDEADBEEF ^ c;
    ulong a = d += c = c << 15 | c >> -15;
    ulong b = a += d = d << 52 | d >> -52;
    c ^= b += a = a << 26 | a >> -26;
    d ^= c += b = b << 51 | b >> -51;
    a ^= d += c = c << 28 | c >> -28;
    b ^= a += d = d << 9 | d >> -9;
    c ^= b += a = a << 47 | a >> -47;
    d ^= c += b << 54 | b >> -54;
    a ^= d += c << 32 | c >> 32;
    a += d << 25 | d >> -25;
    return (int)(a >> 1);
  }
}

And then my power-of-two hash table didn't suck any more.

This disturbed me though, because the above shouldn't work. Or more precisely, it shouldn't work unless the original GetHashCode() was poor in a very particular way.

Re-mixing a hashcode can't improve a great hashcode, because the only possible effect is that we introduce a few more collisions.

Re-mixing a hash code can't improve a terrible hash code, because the only possible effect is we change e.g. a large number of collisions on value 53 to a large number of value 18,3487,291.

Re-mixing a hash code can only improve a hash code that did at least fairly well in avoiding absolute collisions throughout its range (2³² possible values) but badly at avoiding collisions when modulo'd down for actual use in a hash table. While the simpler modulo of a power-of-two table made this more apparent, it was also having a negative effect with the more common prime-number tables, that just wasn't as obvious (the extra work in rehashing would outweigh the benefit, but the benefit would still be there).

Edit: I was also using open-addressing, which would also have increased the sensitivity to collision, perhaps more so than the fact it was power-of-two.

And well, it was disturbing how much the string.GetHashCode() implementations in .NET (or study here) could be improved this way (on the order of tests running about 20-30 times faster due to fewer collisions) and more disturbing how much my own hash codes could be improved (much more than that).

All the GetHashCode() implementations I'd coded in the past, and indeed used as the basis of answers on this site, were much worse than I'd throught. Much of the time it was "good enough" for much of the uses, but I wanted something better.

So I put that project to one side (it was a pet project anyway) and started looking at how to produce a good, well-distributed hash code in .NET quickly.

In the end I settled on porting SpookyHash to .NET. Indeed the code above is a fast-path version of using SpookyHash to produce a 32-bit output from a 32-bit input.

Now, SpookyHash is not a nice quick to remember piece of code. My port of it is even less so because I hand-inlined a lot of it for better speed*. But that's what code reuse is for.

Then I put that project to one side, because just as the original project had produced the question of how to produce a better hash code, so that project produced the question of how to produce a better .NET memcpy.

Then I came back, and produced a lot of overloads to easily feed just about all of the native types (except decimal†) into a hash code.

It's fast, for which Bob Jenkins deserves most of the credit because his original code I ported from is faster still, especially on 64-bit machines which the algorithm is optimised for‡.

The full code can be seen at https://bitbucket.org/JonHanna/spookilysharp/src but consider that the code above is a simplified version of it.

However, since it's now already written, one can make use of it more easily:

public override int GetHashCode()
{
  var hash = new SpookyHash();
  hash.Update(field1);
  hash.Update(field2);
  hash.Update(field3);
  return hash.Final().GetHashCode();
}

It also takes seed values, so if you need to deal with untrusted input and want to protect against Hash DoS attacks you can set a seed based on uptime or similar, and make the results unpredictable by attackers:

private static long hashSeed0 = Environment.TickCount;
private static long hashSeed1 = DateTime.Now.Ticks;
public override int GetHashCode()
{
  //produce different hashes ever time this application is restarted
  //but remain consistent in each run, so attackers have a harder time
  //DoSing the hash tables.
  var hash = new SpookyHash(hashSeed0, hashSeed1);
  hash.Update(field1);
  hash.Update(field2);
  hash.Update(field3);
  return hash.Final().GetHashCode();
}

*A big surprise in this is that hand-inlining a rotation method that returned (x << n) | (x >> -n) improved things. I would have been sure that the jitter would have inlined that for me, but profiling showed otherwise.

†decimal isn't native from the .NET perspective though it is from the C#. The problem with it is that its own GetHashCode() treats precision as significant while its own Equals() does not. Both are valid choices, but not mixed like that. In implementing your own version, you need to choose to do one, or the other, but I can't know which you'd want.

‡By way of comparison. If used on a string, the SpookyHash on 64 bits is considerably faster than string.GetHashCode() on 32 bits which is slightly faster than string.GetHashCode() on 64 bits, which is considerably faster than SpookyHash on 32 bits, though still fast enough to be a reasonable choice.

The standard ERB templating system may work for your scenario.

def merge_into_string(animal, second_animal, action)
  template = 'The <%=animal%> <%=action%> the <%=second_animal%>'
  ERB.new(template).result(binding)
end

merge_into_string('tiger', 'deer', 'eats')
=> "The tiger eats the deer"

merge_into_string('bird', 'worm', 'finds')
=> "The bird finds the worm"

<script ...
  function(){
   var someJsVar = "<c:out value='${someJstLVarFromBackend}'/>";

  }
</script>

This works even if you dont have a hidden/non-hidden input field set somewhere in the jsp.

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

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

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

<meta charset = "UTF-8" />

Look into twitter cards.

The trick is not in the button but rather the page you are sharing. Twitter Cards pull the image from the meta tags similar to facebook sharing.

Example:

<meta name="twitter:card" content="summary_large_image">
<meta name="twitter:site" content="@site_username">
<meta name="twitter:title" content="Top 10 Things Ever">
<meta name="twitter:description" content="Up than 200 characters.">
<meta name="twitter:creator" content="@creator_username">
<meta name="twitter:image" content="http://placekitten.com/250/250">
<meta name="twitter:domain" content="YourDomain.com">

Made an improvement code by @Ipsita - for use asynchronous read\write file I/O

    string data = await tr.ReadLineAsync();
    tr.Close();

    await tw.WriteLineAsync(data + dataToWrite);
    tw.Close();

Unit test: testing of an individual module or independent component in an application is known to be unit testing. The unit testing will be done by the developer.

Integration test: combining all the modules and testing the application to verify the communication and the data flow between the modules are working properly or not. This testing also performed by developers.

Smoke test In a smoke test they check the application in a shallow and wide manner. In smoke testing they check the main functionality of the application. If there is any blocker issue in the application they will report to developer team, and the developing team will fix it and rectify the defect, and give it back to the testing team. Now testing team will check all the modules to verify that changes made in one module will impact the other module or not. In smoke testing the test cases are scripted.

Regression testing executing the same test cases repeatedly to ensure tat the unchanged module does not cause any defect. Regression testting comes under functional testing

A way that might be more convenient: where you want a breakpoint, write a no-op if statement and set a breakpoint in its contents.

if(tablist[i].equalsIgnoreCase("LEADDELEGATES")) {
-->    int noop = 0; //don't do anything
}

(the breakpoint is represented by the arrow)

This way, the breakpoint only triggers if your condition is true. This could potentially be easier without that many pop-ups.

public Form1()
{
InitializeComponent();
//this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.FixedSingle;
this.MaximizeBox = false;
this.MinimizeBox = false;
}

The reply by Phil Sacre was correct however the session shouldn't be used just for the hell of it. You should only use this for values which really need to live for the lifetime of the session, such as a user login. It's common to see people overuse the session and run into more issues, especially when dealing with a collection or when users return to a page they previously visited only to find they have values still remaining from a previous visit. A smart program minimizes the scope of variables as much as possible, a bad one uses session too much.

Your module and your class AthleteList have the same name. The line

import AthleteList

imports the module and creates a name AthleteList in your current scope that points to the module object. If you want to access the actual class, use

AthleteList.AthleteList

In particular, in the line

return(AthleteList(templ.pop(0), templ.pop(0), templ))

you are actually accessing the module object and not the class. Try

return(AthleteList.AthleteList(templ.pop(0), templ.pop(0), templ))

This worked for me...on every device

    <EditText
        android:maxLines="1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:textSize="15sp"
        android:layout_centerVertical="true"
        android:textColor="#000"

        android:background="@null"
        android:inputType="text"
        android:hint="Enter Address, City or Zip Code"
        android:imeOptions="actionSearch"
        />

In Java code:

mSearchText.setOnEditorActionListener(new TextView.OnEditorActionListener() {

        @Override
        public boolean onEditorAction(TextView textView, int actionId, KeyEvent keyEvent) {
            if(actionId == EditorInfo.IME_ACTION_SEARCH
                    || actionId == EditorInfo.IME_ACTION_DONE
                    || keyEvent.getAction() == KeyEvent.ACTION_DOWN
                    || keyEvent.getAction() == KeyEvent.KEYCODE_ENTER){

                //execute our method for searching
            }

            return false;
        }
    });

In case you need to use it with Javascript

We can use arguments[0].click() to simulate click operation.

var element = element(by.linkText('webdriverjs'));
browser.executeScript("arguments[0].click()",element);

Make sure the newest Framework (the one you compiled your app with) is first in the PATH. That solved the problem for me. (Found on a forum)

Below is the solution with Kotlin.

You can copy your InputStream into ByteArray

val inputStream = ...

val byteOutputStream = ByteArrayOutputStream()
inputStream.use { input ->
    byteOutputStream.use { output ->
        input.copyTo(output)
    }
}

val byteInputStream = ByteArrayInputStream(byteOutputStream.toByteArray())

If you need to read the byteInputStream multiple times, call byteInputStream.reset() before reading again.

    "VALUES(@na,@occ);SELECT SCOPE_IDENTITY();",con))
{
    cmd.Parameters.AddWithValue("@na", Mem_NA);
    cmd.Parameters.AddWithValue("@occ", Mem_Occ);
    con.Open();

    int modified = cmd.ExecuteNonQuery();

    if (con.State == System.Data.ConnectionState.Open) con.Close();
        return modified;
}

You can set it as a no title bar theme in the activity's xml in the AndroidManifest

    <activity 
        android:name=".AnActivity"
        android:label="@string/a_string"
        android:theme="@android:style/Theme.NoTitleBar">
    </activity>

Apparently the index 'productid' is missing from your html form. Inspect your html inputs first. eg <input type="text" name="productid" value=""> But this will handle the current error PHP is raising.

  $rowID = isset($_POST['rowID']) ? $_POST['rowID'] : '';
  $productid = isset($_POST['productid']) ? $_POST['productid'] : '';
  $name = isset($_POST['name']) ? $_POST['name'] : '';
  $price = isset($_POST['price']) ? $_POST['price'] : '';
  $description = isset($_POST['description']) ? $_POST['description'] : '';

A simple way to remove spaces from the whole string is to use the explode function and print the whole string using a for loop.

 $text = $_POST['string'];
            $a=explode(" ", $text);
            $count=count($a);
            for($i=0;$i<$count; $i++){

                echo $a[$i];
            }

Something like this:

var option = document.createElement("option");
option.text = "Text";
option.value = "myvalue";
var select = document.getElementById("id-to-my-select-box");
select.appendChild(option);

I think what you need might be simply:

\d( \w)?

Note that your regex would have worked too if it was written as \d \w|\d instead of \d|\d \w.

This is because in your case, once the regex matches the first option, \d, it ceases to search for a new match, so to speak.

If you want to know how to read a file, within a directory, and do something with it, here you go. This also shows you how to run a command through the power shell. This is in TypeScript! I had trouble with this, so I hope this helps someone one day. Feel free to down vote me if you think its THAT unhelpful. What this did for me was webpack all of my .ts files in each of my directories within a certain folder to get ready for deployment. Hope you can put it to use!

import * as fs from 'fs';
let path = require('path');
let pathDir = '/path/to/myFolder';
const execSync = require('child_process').execSync;

let readInsideSrc = (error: any, files: any, fromPath: any) => {
    if (error) {
        console.error('Could not list the directory.', error);
        process.exit(1);
    }

    files.forEach((file: any, index: any) => {
        if (file.endsWith('.ts')) {
            //set the path and read the webpack.config.js file as text, replace path
            let config = fs.readFileSync('myFile.js', 'utf8');
            let fileName = file.replace('.ts', '');
            let replacedConfig = config.replace(/__placeholder/g, fileName);

            //write the changes to the file
            fs.writeFileSync('myFile.js', replacedConfig);

            //run the commands wanted
            const output = execSync('npm run scriptName', { encoding: 'utf-8' });
            console.log('OUTPUT:\n', output);

            //rewrite the original file back
            fs.writeFileSync('myFile.js', config);
        }
    });
};

// loop through all files in 'path'
let passToTest = (error: any, files: any) => {
    if (error) {
        console.error('Could not list the directory.', error);
        process.exit(1);
    }

    files.forEach(function (file: any, index: any) {
        let fromPath = path.join(pathDir, file);
        fs.stat(fromPath, function (error2: any, stat: any) {
            if (error2) {
                console.error('Error stating file.', error2);
                return;
            }

            if (stat.isDirectory()) {
                fs.readdir(fromPath, (error3: any, files1: any) => {
                    readInsideSrc(error3, files1, fromPath);
                });
            } else if (stat.isFile()) {
                //do nothing yet
            }

        });
    });
};

//run the bootstrap
fs.readdir(pathDir, passToTest);

See row in ?base::row. This gives the row indices for any matrix-like object.

"Requery" is indeed what you what you want to run, but you could do that in Form A's "On Got Focus" event. If you have code in your Form_Load, perhaps you can move it to Form_Got_Focus.

The wb indicates that the file is opened for writing in binary mode.

When writing in binary mode, Python makes no changes to data as it is written to the file. In text mode (when the b is excluded as in just w or when you specify text mode with wt), however, Python will encode the text based on the default text encoding. Additionally, Python will convert line endings (\n) to whatever the platform-specific line ending is, which would corrupt a binary file like an exe or png file.

Text mode should therefore be used when writing text files (whether using plain text or a text-based format like CSV), while binary mode must be used when writing non-text files like images.

In WPF the titlebar is part of the non-client area, which can't be modified through the WPF window class. You need to manipulate the Win32 handles (if I remember correctly).
This article could be helpful for you: Custom Window Chrome in WPF.

There's also a funny trick to lock the parent's scrollTop when mouse hovers over a scrollable element. This way you don't have to implement your own wheel scrolling.

Here's an example for preventing document scroll, but it can be adjusted for any element.

scrollable.mouseenter(function ()
{
  var scroll = $(document).scrollTop();
  $(document).on('scroll.trap', function ()
  {
    if ($(document).scrollTop() != scroll) $(document).scrollTop(scroll);
  });
});

scrollable.mouseleave(function ()
{
  $(document).off('scroll.trap');
});

For cases where you also wish to have the option of setting 'b' to None:

def p(self, **kwargs):
    b = kwargs.get('b', self.a)
    print b

In case you are working with Maven and Apache Wicket also check for the following in order to try to resolve the issue with Font-Awesome and icons not being loaded:

If you have placed your files for example in the following file structure

/src
 /main
  /java
   /your
    /package
     /css
      font-awesome.css
     /font
      fontawesome-webfont.eot
      fontawesome-webfont.svg
      fontawesome-webfont.svgz
      fontawesome-webfont.ttf
      fontawesome-webfont.woff

Check 1) Are you correctly using a Package Resource Guard in order to allow to load the font files correctly?

Example from your class which extends WebApplication:

@Override
public void init() {
    super.init();   
    get().getResourceSettings().setPackageResourceGuard(new PackageResourceGuard());

}

Check 2) After you have made sure that all fonts are correctly transferred to the Web Browser, check for what has been actually transferred to the Web Browser, i.e., did the integrity of the font files change? Compare the files in your source directory and the files transferred to the Web Browser using, e.g., the Web Developer Toolbar of Firefox and DiffDog (for file comparison).

In particular if you are using Maven be aware of resource filtering. Do not filter the folder where your /font files are contained - otherwise they will be corrupted.

Example from your pom.xml

<build>
    <finalName>Your project</finalName>
    <resources>
        <resource>
            <filtering>true</filtering>
            <directory>src/main/resources</directory>
        </resource>
        <resource>
            <filtering>false</filtering>
            <directory>src/main/java</directory>
            <includes>
                <include>**</include>
            </includes>
            <excludes>
                <exclude>**/*.java</exclude>
            </excludes>
        </resource>
    </resources>
</build>

In the example above we do not filter the folder src/main/java, where the css and font files are contained.

For further information on the filtering of binary data please also see the documentation:

http://maven.apache.org/plugins/maven-resources-plugin/examples/filter.html

In particular the documentation warns: "Warning: Do not filter files with binary content like images! This will most likely result in corrupt output. If you have both text files and binary files as resources, you need to declare two mutually exclusive resource sets. The first resource set defines the files to be filtered and the other resource set defines the files to copy unaltered..."

There are 8 bits in a byte (normally speaking in Windows).

However, if you are dealing with characters, it will depend on the charset/encoding. Unicode character can be 2 or 4 bytes, so that would be 16 or 32 bits, whereas Windows-1252 sometimes incorrectly called ANSI is only 1 bytes so 8 bits.

In Asian version of Windows and some others, the entire system runs in double-byte, so a character is 16 bits.

EDITED

Per Matteo's comment, all contemporary versions of Windows use 16-bits internally per character.

This problem happens when you install the JDK by _uncompressing_ it instead of _executing_ it.

By example:

unzip jdk-6u45-linux-x64.bin  (wrong)

sh ./jdk-6u45-linux-x64.bin   (right)

In the first scenario, the runtime libraries, as rt.jar, don't get automatically uncompresessed (thus, you can find the rt.pack files, etc. instead of the .jar ones).

You may also try the following code with exception handling. Here you have a method removeLast(String s, int n) (it is actually an modified version of masud.m's answer). You have to provide the String s and how many char you want to remove from the last to this removeLast(String s, int n) function. If the number of chars have to remove from the last is greater than the given String length then it throws a StringIndexOutOfBoundException with a custom message -

public String removeLast(String s, int n) throws StringIndexOutOfBoundsException{

        int strLength = s.length();

        if(n>strLength){
            throw new StringIndexOutOfBoundsException("Number of character to remove from end is greater than the length of the string");
        }

        else if(null!=s && !s.isEmpty()){

            s = s.substring(0, s.length()-n);
        }

        return s;

    }

document.getElementById("printf").contentWindow.print();

Same origin policy applies.

In my case removing Initail Cataloge=.... from connection string resolved the issue

If you don't mind importing the json module, then the best way to handle it is through json.JSONDecodeError (or json.decoder.JSONDecodeError as they are the same) as using default errors like ValueError could catch also other exceptions not necessarily connected to the json decode one.

from json.decoder import JSONDecodeError


try:
    qByUser = byUsrUrlObj.read()
    qUserData = json.loads(qByUser).decode('utf-8')
    questionSubjs = qUserData["all"]["questions"]
except JSONDecodeError as e:
    # do whatever you want

//EDIT (Oct 2020):

As @Jacob Lee noted in the comment, there could be the basic common TypeError raised when the JSON object is not a str, bytes, or bytearray. Your question is about JSONDecodeError, but still it is worth mentioning here as a note; to handle also this situation, but differentiate between different issues, the following could be used:

from json.decoder import JSONDecodeError


try:
    qByUser = byUsrUrlObj.read()
    qUserData = json.loads(qByUser).decode('utf-8')
    questionSubjs = qUserData["all"]["questions"]
except JSONDecodeError as e:
    # do whatever you want
except TypeError as e:
    # do whatever you want in this case

in java 7 Calendar one line

new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS").format(Calendar.getInstance().getTime())

I have another simple idea
Let's use the echo command in cmd ,

echo ./idea > .gitignore

this will create the .gitignore file having text content "./idea"
you may now manually change data from the file using text editor.

or simply

console :

echo .gitignore notepad.exe

to instantly edit gitignore.

If you dont know which files are should be gitignored for your IDE or Operating System just goto www.gitignore.io

gitignore.io - here it wll generate the gitignore commands or text for you just say your api or os thats it!. Just copy and paste into your file. simple!

Run this from the branch where you want the file to end up:

git checkout otherbranch myfile.txt

General formulas:

git checkout <commit_hash> <relative_path_to_file_or_dir>
git checkout <remote_name>/<branch_name> <file_or_dir>

Some notes (from comments):

• Using the commit hash you can pull files from any commit
• This works for files and directories
• overwrites the file myfile.txt and mydir
• Wildcards don't work, but relative paths do
• Multiple paths can be specified

an alternative:

git show commit_id:path/to/file > path/to/file

You need to convert all the values in the column to date in order to sort by date.

There is also zzos. (Full disclosure: I wrote it). It only decompiles the actual resources, not the dex part (baksmali, which I did not write, does an excellent job of handling that part).

Zzos is much less known than apktool, but there are some APKs that are better handled by it (and vice versa - more on that later). Mostly, APKs containing custom resource types (not modifiers) were not handled by apktool the last time I checked, and are handled by zzos. There are also some cases with escaping that zzos handles better.

On the negative side of things, zzos (current version) requires a few support tools to install. It is written in perl (as opposed to APKTool, which is written in Java), and uses aapt for the actual decompilation. It also does not decompile attrib resources yet (which APKTool does).

The meaning of the name is "aapt", Android's resource compiler, shifted down one letter.

For Mac using native library:

import Quartz as q

#x and y individually
q.NSEvent.mouseLocation().x
q.NSEvent.mouseLocation().y

If the Quartz-wrapper is not installed:

python3 -m pip install -U pyobjc-framework-Quartz

(The question specify Windows, but a lot of Mac users come here because of the title)

Before Mysql version 5.0.3 Varchar datatype can store 255 character, but from 5.0.3 it can be store 65,535 characters.

BUT it has a limitation of maximum row size of 65,535 bytes. It means including all columns it must not be more than 65,535 bytes.

In your case it may possible that when you are trying to set more than 10000 it is exceeding more than 65,535 and mysql will gives the error.

Since the id is sufficient for detecting duplicates, and the id is hashable: run 'em through a dictionary that has the id as the key. The value for each key is the original dictionary.

deduped_dicts = dict((item["id"], item) for item in list_of_dicts).values()

In Python 3, values() doesn't return a list; you'll need to wrap the whole right-hand-side of that expression in list(), and you can write the meat of the expression more economically as a dict comprehension:

deduped_dicts = list({item["id"]: item for item in list_of_dicts}.values())

Note that the result likely will not be in the same order as the original. If that's a requirement, you could use a Collections.OrderedDict instead of a dict.

As an aside, it may make a good deal of sense to just keep the data in a dictionary that uses the id as key to begin with.

Here's my EmguCV (a C# port of OpenCV) solution:

public static Image<TColor, TDepth> Rotate90<TColor, TDepth>(this Image<TColor, TDepth> img)
    where TColor : struct, IColor
    where TDepth : new()
{
    var rot = new Image<TColor, TDepth>(img.Height, img.Width);
    CvInvoke.cvTranspose(img.Ptr, rot.Ptr);
    rot._Flip(FLIP.HORIZONTAL);
    return rot;
}

public static Image<TColor, TDepth> Rotate180<TColor, TDepth>(this Image<TColor, TDepth> img)
    where TColor : struct, IColor
    where TDepth : new()
{
    var rot = img.CopyBlank();
    rot = img.Flip(FLIP.VERTICAL);
    rot._Flip(FLIP.HORIZONTAL);
    return rot;
}

public static void _Rotate180<TColor, TDepth>(this Image<TColor, TDepth> img)
    where TColor : struct, IColor
    where TDepth : new()
{
    img._Flip(FLIP.VERTICAL);
    img._Flip(FLIP.HORIZONTAL);
}

public static Image<TColor, TDepth> Rotate270<TColor, TDepth>(this Image<TColor, TDepth> img)
    where TColor : struct, IColor
    where TDepth : new()
{
    var rot = new Image<TColor, TDepth>(img.Height, img.Width);
    CvInvoke.cvTranspose(img.Ptr, rot.Ptr);
    rot._Flip(FLIP.VERTICAL);
    return rot;
}

Shouldn't be too hard to translate it back into C++.

There must be a user in the AllowUsers section, in the config file /etc/ssh/ssh_config, in the remote machine. You might have to restart sshd after editing the config file.

And then you can copy for example the file "test.txt" from a remote host to the local host

scp [email protected]:test.txt /local/dir

@cool_cs you can user ~ symbol ~/Users/djorge/Desktop if it's your home dir.

In UNIX, absolute paths must start with '/'.

As others have already pointed out, the nameof operator does insert the name that the element was given in the sourcecode.

I would like to add that this is a really good idea in terms of refactoring since it makes this string refactoring safe. Previously, I used a static method which utilized reflection for the same purpose, but that has a runtime performance impact. The nameof operator has no runtime performance impact; it does its work at compile time. If you take a look at the MSIL code you will find the string embedded. See the following method and its disassembled code.

static void Main(string[] args)
{
    Console.WriteLine(nameof(args));
    Console.WriteLine("regular text");
}

// striped nops from the listing
IL_0001 ldstr args
IL_0006 call System.Void System.Console::WriteLine(System.String)
IL_000C ldstr regular text
IL_0011 call System.Void System.Console::WriteLine(System.String)
IL_0017 ret

However, that can be a drawback if you plan to obfuscate your software. After obfuscation the embedded string may no longer match the name of the element. Mechanisms that rely on this text will break. Examples for that, including but not limited to are: Reflection, NotifyPropertyChanged ...

Determining the name during runtime costs some performance, but is safe for obfuscation. If obfuscation is neither required nor planned, I would recommend using the nameof operator.

  public class TestDate {

    public static void main(String[] args) {
    // TODO Auto-generated method stub

    String fromDate = "18-FEB-2018";
    String toDate = "20-FEB-2018";

    String requestDate = "19/02/2018";  
    System.out.println(checkBetween(requestDate,fromDate, toDate));
}

public static boolean checkBetween(String dateToCheck, String startDate, String endDate) {
    boolean res = false;
    SimpleDateFormat fmt1 = new SimpleDateFormat("dd-MMM-yyyy"); //22-05-2013
    SimpleDateFormat fmt2 = new SimpleDateFormat("dd/MM/yyyy"); //22-05-2013
    try {
     Date requestDate = fmt2.parse(dateToCheck);
     Date fromDate = fmt1.parse(startDate);
     Date toDate = fmt1.parse(endDate);
     res = requestDate.compareTo(fromDate) >= 0 && requestDate.compareTo(toDate) <=0;
    }catch(ParseException pex){
        pex.printStackTrace();
    }
    return res;
   }
 }

ASP.NET Web API is a framework that makes it easy to build HTTP services that reach a broad range of clients, including browsers and mobile devices. ASP.NET Web API is an ideal platform for building RESTful applications on the .NET Framework.

REST

RESTs sweet spot is when you are exposing a public API over the internet to handle CRUD operations on data. REST is focused on accessing named resources through a single consistent interface.

SOAP

SOAP brings it’s own protocol and focuses on exposing pieces of application logic (not data) as services. SOAP exposes operations. SOAP is focused on accessing named operations, each implement some business logic through different interfaces.

Though SOAP is commonly referred to as “web services” this is a misnomer. SOAP has very little if anything to do with the Web. REST provides true “Web services” based on URIs and HTTP.

Reference: http://spf13.com/post/soap-vs-rest

And finally: What they could be referring to is REST vs. RPC See this: http://encosia.com/rest-vs-rpc-in-asp-net-web-api-who-cares-it-does-both/

Using awk:

export INDEX=2
export VALUE=bar

awk -F, '$'$INDEX' ~ /^'$VALUE'$/ {print}' inputfile.csv

Edit: As per Dennis Williamson's excellent comment, this could be much more cleanly (and safely) written by defining awk variables using the -v switch:

awk -F, -v index=$INDEX -v value=$VALUE '$index == value {print}' inputfile.csv

Jeez...with variables, and everything, awk is almost a real programming language...

Just add extra data to the Intent you use to call your activity.

In the caller activity :

Intent i = new Intent(this, TheNextActivity.class);
i.putExtra("id", id);
startActivity(i);

Inside the onCreate() of the activity you call :

Bundle b = getIntent().getExtras();
int id = b.getInt("id");

I would recommend to use Bootstrap. http://getbootstrap.com/. This approach is very straight-forward and light weight.

<div class="navbar navbar-inverse navbar-fixed-top">
   <div class="container">
      <div class="navbar-collapse collapse">
         <ul class="nav navbar-nav navbar-fixed-top">
            <li><a href="#home"> <br>BLINK</a></li>
                <li><a href="#news"><br>ADVERTISING WITH BLINK</a></li>
                <li><a href="#contact"><br>EDUCATING WITH BLINK</a></li>
                <li><a href="#about"><br>ABOUT US</a></li>
            </ul>
        </div>
    </div>
</div>

You need to include the Bootstrap into your project, which will include the necessary scripts and styles. Then just call the class 'navbar-fixed-top'. This will do the trick. See above example

I think you want:

items.GroupBy(item => item.Order.Customer)
     .Select(group => new { Customer = group.Key, Items = group.ToList() })
     .ToList() 

If you want to continue use the overload of GroupBy you are currently using, you can do:

items.GroupBy(item => item.Order.Customer, 
              (key, group) =>  new { Customer = key, Items = group.ToList() })
     .ToList() 

...but I personally find that less clear.

A good way to avoid loading multiple CSS files or to have inline CSS is to hand a class to the body tag depending on the version of Internet Explorer. If you only need general IE hacks, you can do something like this, but it can be extended to be version specific:

<!--[if IE ]><body class="ie"><![endif]-->
<!--[if !IE]>--><body><!--<![endif]-->

Now in your css code, you can simply do:

.ie .abc {
  position:absolute;
  left:30;
  top:-10;
}

This also keeps your CSS files valid, as you do not have to use dirty (and invalid) CSS hacks.

For those late-comers that are looking for a solution that "just works":

#include <utility>
#include <iostream>

template< typename T >
class Y {

    template< bool cond, typename U >
    using resolvedType  = typename std::enable_if< cond, U >::type; 

    public:
        template< typename U = T > 
        resolvedType< true, U > foo() {
            return 11;
        }
        template< typename U = T >
        resolvedType< false, U > foo() {
            return 12;
        }

};


int main() {
    Y< double > y;

    std::cout << y.foo() << std::endl;
}

Compile with:

g++ -std=gnu++14 test.cpp 

Running gives:

./a.out 
11

I'll give an example to make it clearer:

• x: input image of shape [2, 3], 1 channel
• valid_pad: max pool with 2x2 kernel, stride 2 and VALID padding.
• same_pad: max pool with 2x2 kernel, stride 2 and SAME padding (this is the classic way to go)

The output shapes are:

• valid_pad: here, no padding so the output shape is [1, 1]
• same_pad: here, we pad the image to the shape [2, 4] (with -inf and then apply max pool), so the output shape is [1, 2]

x = tf.constant([[1., 2., 3.],
                 [4., 5., 6.]])

x = tf.reshape(x, [1, 2, 3, 1])  # give a shape accepted by tf.nn.max_pool

valid_pad = tf.nn.max_pool(x, [1, 2, 2, 1], [1, 2, 2, 1], padding='VALID')
same_pad = tf.nn.max_pool(x, [1, 2, 2, 1], [1, 2, 2, 1], padding='SAME')

valid_pad.get_shape() == [1, 1, 1, 1]  # valid_pad is [5.]
same_pad.get_shape() == [1, 1, 2, 1]   # same_pad is  [5., 6.]

This one worked for me, it also have the advantage of expecting a cultureinfo as parameter to test the formula with different cultures. If empty, it gets the current culture info... valid values are like: "it", "en-us", "fr", ... ando so on. The trick is to subtract the week number of the first day of the year, that may be 1 to indicate that the first day is within the first week. Hope this helps.

Public Shared Function FirstDayOfWeek(ByVal year As Integer, ByVal weekNumber As Integer, ByVal culture As String) As Date
    Dim cInfo As System.Globalization.CultureInfo
    If culture = "" Then

Following are the build-in constants you can use as per your requirements for getting the paths in Codeigniter:

EXT: The PHP file extension

FCPATH: Path to the front controller (this file) (root of CI)

SELF: The name of THIS file (index.php)

BASEPATH: Path to the system folder

APPPATH: The path to the “application” folder

For the security reason you can't do that. You must choose Flash for copying to the clipboard.

In addition, apparently, this error will happen if you clone into NTFS Ram Drive.

Named exports:

Let's say you create a file called utils.js, with utility functions that you want to make available for other modules (e.g. a React component). Then you would make each function a named export:

export function add(x, y) {
  return x + y
}

export function mutiply(x, y) {
  return x * y
}

Assuming that utils.js is located in the same directory as your React component, you can use its exports like this:

import { add, multiply } from './utils.js';
...
add(2, 3) // Can be called wherever in your component, and would return 5.

Or if you prefer, place the entire module's contents under a common namespace:

import * as utils from './utils.js'; 
...
utils.multiply(2,3)

Default exports:

If you on the other hand have a module that only does one thing (could be a React class, a normal function, a constant, or anything else) and want to make that thing available to others, you can use a default export. Let's say we have a file log.js, with only one function that logs out whatever argument it's called with:

export default function log(message) {
  console.log(message);
}

This can now be used like this:

import log from './log.js';
...
log('test') // Would print 'test' in the console.

You don't have to call it log when you import it, you could actually call it whatever you want:

import logToConsole from './log.js';
...
logToConsole('test') // Would also print 'test' in the console.

Combined:

A module can have both a default export (max 1), and named exports (imported either one by one, or using * with an alias). React actually has this, consider:

import React, { Component, PropTypes } from 'react';

While : your condition is at the begin of the loop block, and makes possible to never enter the loop.

Do While : your condition is at the end of the loop block, and makes obligatory to enter the loop at least one time.

I like Zarembisty's answer. Although, if you want to be more explicit, you can always do:

if len(my_list) == 0:
    print "my_list is empty"

Try to run Your XAMPP Control Panel as Run as administrator, then install Apache and MySQL.

When XAMPP opens, ensure that Apache and MySQL services are stopped.

Now just check/tick on Apache and Mysql service module.

Now Apache and MySQL will be added to window services. You can set these services to start when Windows boots.

The short answer is that the syntax is this.dataset.whatever.

Your code should look like this:

<div data-uid="aaa" data-name="bbb" data-value="ccc"
    onclick="fun(this.dataset.uid, this.dataset.name, this.dataset.value)">

Another important note: Javascript will always strip out hyphens and make the data attributes camelCase, regardless of whatever capitalization you use. data-camelCase will become this.dataset.camelcase and data-Camel-case will become this.dataset.camelCase.

jQuery (after v1.5 and later) always uses lowercase, regardless of your capitalization.

So when referencing your data attributes using this method, remember the camelCase:

<div data-this-is-wild="yes, it's true"
    onclick="fun(this.dataset.thisIsWild)">

Also, you don't need to use commas to separate attributes.

In Tomcat 8.0.44 I did this: create the JNDI on Tomcat's server.xml between the tag "GlobalNamingResources" For example:

<GlobalNamingResources>_x000D_
    <!-- Editable user database that can also be used by_x000D_
         UserDatabaseRealm to authenticate users_x000D_
    -->_x000D_
  <!-- Other previus resouces -->_x000D_
    <Resource auth="Container" driverClassName="org.postgresql.Driver" global="jdbc/your_jndi" _x000D_
    maxActive="100" maxIdle="20" maxWait="1000" minIdle="5" name="jdbc/your_jndi" password="your_password" _x000D_
    type="javax.sql.DataSource" url="jdbc:postgresql://localhost:5432/your_database?user=postgres" username="database_username"/>_x000D_
  </GlobalNamingResources>

<?xml version="1.0" encoding="UTF-8"?>_x000D_
<Context reloadable="true" >_x000D_
   <ResourceLink name="jdbc/your_jndi"_x000D_
      global="jdbc/your_jndi"_x000D_
      auth="Container"_x000D_
      type="javax.sql.DataSource" />_x000D_
</Context>

So if you're using Hiberte with spring you can tell to him to use the JNDI in your persistence.xml

<?xml version="1.0" encoding="UTF-8"?>_x000D_
<persistence xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"_x000D_
 xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"_x000D_
 version="2.0" xmlns="http://java.sun.com/xml/ns/persistence">_x000D_
 <persistence-unit name="UNIT_NAME" transaction-type="RESOURCE_LOCAL">_x000D_
  <provider>org.hibernate.ejb.HibernatePersistence</provider>_x000D_
_x000D_
  <properties>_x000D_
   <property name="javax.persistence.jdbc.driver"   value="org.postgresql.Driver" />_x000D_
   <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQL82Dialect" />_x000D_
   _x000D_
   <!--  <property name="hibernate.jdbc.time_zone" value="UTC"/>-->_x000D_
   <property name="hibernate.hbm2ddl.auto" value="update" />_x000D_
   <property name="hibernate.show_sql" value="false" />_x000D_
   <property name="hibernate.format_sql" value="true"/>     _x000D_
  </properties>_x000D_
 </persistence-unit>_x000D_
</persistence>

So in your spring.xml you can do that:

<bean id="postGresDataSource" class="org.springframework.jndi.JndiObjectFactoryBean">_x000D_
   <property name="jndiName" value="java:comp/env/jdbc/your_jndi" />_x000D_
  </bean>_x000D_
     _x000D_
        <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">_x000D_
              <property name="persistenceUnitName" value="UNIT_NAME" />_x000D_
              <property name="dataSource" ref="postGresDataSource" />_x000D_
              <property name="jpaVendorAdapter"> _x000D_
                 <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />_x000D_
              </property>_x000D_
        </bean>

<property name="jndiName" value="java:comp/env/jdbc/your_jndi" />

In this example I used spring with xml but you can do this programmaticaly if you prefer.

That's it, I hope helped.

jXPanel6.setVisible(jXPanel6.isVisible());

or in your form:

jXPanel6.setVisible(jXPanel6.isVisible()?true:false);

Why not just this in that case?

args = ['A', 'C']
sql = 'SELECT fooid FROM foo WHERE bar IN (%s)' 
in_p  =', '.join(list(map(lambda arg:  "'%s'" % arg, args)))
sql = sql % in_p
cursor.execute(sql)

results in:

SELECT fooid FROM foo WHERE bar IN ('A', 'C')

<div onclick="location.href='#';" style="cursor: pointer;">
</div>

Why not use regular expressions:

import urllib2
import re
url = "http://www.somewhere.com"
page = urllib2.urlopen(url)
page = page.read()
links = re.findall(r"<a.*?\s*href=\"(.*?)\".*?>(.*?)</a>", page)
for link in links:
    print('href: %s, HTML text: %s' % (link[0], link[1]))

Nowadays you can get correct timezone of a user having just one line of code:

const timezone = Intl.DateTimeFormat().resolvedOptions().timeZone;

source: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/DateTimeFormat/resolvedOptions

You can then use moment-timezone to parse timezone like:

const currentTime = moment().tz(timezone).format();

Try this:

string foo = @"D:\Projects\Some\Kind\Of\Pathproblem\wuhoo.xml";

The problem is that in a string, a \ is an escape character. By using the @ sign you tell the compiler to ignore the escape characters.

You can also get by with escaping the \:

string foo = "D:\\Projects\\Some\\Kind\\Of\\Pathproblem\\wuhoo.xml";

http://dev.mysql.com/doc/refman/5.5/en/date-and-time-functions.html

http://www.tutorialspoint.com/mysql/mysql-date-time-functions.htm

use Date function directly. Hope it works

Use cut. Eg. to strip the first 4 characters of each line (i.e. start on the 5th char):

tail -f logfile | grep org.springframework | cut -c 5-

I think you want something along the line of:

Parent:

<Editor name={this.state.fileData} />

Editor:

var Editor = React.createClass({
  displayName: 'Editor',
  propTypes: {
    name: React.PropTypes.string.isRequired
  },
  getInitialState: function() { 
    return {
      value: this.props.name
    };
  },
  handleChange: function(event) {
    this.setState({value: event.target.value});
  },
  render: function() {
    return (
      <form id="noter-save-form" method="POST">
        <textarea id="noter-text-area" name="textarea" value={this.state.value} onChange={this.handleChange} />
        <input type="submit" value="Save" />
      </form>
    );
  }
});

This is basically a direct copy of the example provided on https://facebook.github.io/react/docs/forms.html

Update for React 16.8:

import React, { useState } from 'react';

const Editor = (props) => {
    const [value, setValue] = useState(props.name);

    const handleChange = (event) => {
        setValue(event.target.value);
    };

    return (
        <form id="noter-save-form" method="POST">
            <textarea id="noter-text-area" name="textarea" value={value} onChange={handleChange} />
            <input type="submit" value="Save" />
        </form>
    );
}

Editor.propTypes = {
    name: PropTypes.string.isRequired
};

Some of the answers of this post are valid, but using TypeToken, the Gson library generates a Tree objects whit unreal types for your application.

To get it I had to read the array and convert one by one the objects inside the array. Of course this method is not the fastest and I don't recommend to use it if you have the array is too big, but it worked for me.

It is necessary to include the Json library in the project. If you are developing on Android, it is included:

/**
 * Convert JSON string to a list of objects
 * @param sJson String sJson to be converted
 * @param tClass Class
 * @return List<T> list of objects generated or null if there was an error
 */
public static <T> List<T> convertFromJsonArray(String sJson, Class<T> tClass){

    try{
        Gson gson = new Gson();
        List<T> listObjects = new ArrayList<>();

        //read each object of array with Json library
        JSONArray jsonArray = new JSONArray(sJson);
        for(int i=0; i<jsonArray.length(); i++){

            //get the object
            JSONObject jsonObject = jsonArray.getJSONObject(i);

            //get string of object from Json library to convert it to real object with Gson library
            listObjects.add(gson.fromJson(jsonObject.toString(), tClass));
        }

        //return list with all generated objects
        return listObjects;

    }catch(Exception e){
        e.printStackTrace();
    }

    //error: return null
    return null;
}

I think you have to use the GetValueOrDefault-Methode. The behaviour with ToString("yy...") is not defined if the instance is null.

dt2.GetValueOrDefault().ToString("yyy...");

You need to do two things:

1. Rename and re-order the factor levels before the plot
2. Rename the title of each legend to the same title

The code:

dtt$model <- factor(dtt$model, levels=c("mb", "ma", "mc"), labels=c("MBB", "MAA", "MCC"))

library(ggplot2)
ggplot(dtt, aes(x=year, y=V, group = model, colour = model, ymin = lower, ymax = upper)) +
  geom_ribbon(alpha = 0.35, linetype=0)+ 
  geom_line(aes(linetype=model), size = 1) +       
  geom_point(aes(shape=model), size=4)  +      
  theme(legend.position=c(.6,0.8)) +
  theme(legend.background = element_rect(colour = 'black', fill = 'grey90', size = 1, linetype='solid')) +
  scale_linetype_discrete("Model 1") +
  scale_shape_discrete("Model 1") +
  scale_colour_discrete("Model 1")

However, I think this is really ugly as well as difficult to interpret. It's far better to use facets:

ggplot(dtt, aes(x=year, y=V, group = model, colour = model, ymin = lower, ymax = upper)) +
  geom_ribbon(alpha=0.2, colour=NA)+ 
  geom_line() +       
  geom_point()  +      
  facet_wrap(~model)

is this what are you looking to?

curl_setopt($ch, CURLOPT_HTTPHEADER, array('Expect:'));
$response = curl_exec($ch); 
list($header, $body) = explode("\r\n\r\n", $response, 2);

Change your FirstyActivity to:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button btn_go=(Button)findViewById(R.id.YOUR_BUTTON_ID);
            btn_go.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                  Log.i("clicks","You Clicked B1");
              Intent i=new Intent(
                     MainActivity.this,
                     MainActivity2.class);
              startActivity(i);
            }
        }
    });

}

Hope it will help you.

Tbl.ListRows.Add doesn't work for me and I believe lot others are facing the same problem. I use the following workaround:

    'First check if the last row is empty; if not, add a row
    If table.ListRows.count > 0 Then
        Set lastRow = table.ListRows(table.ListRows.count).Range
        For col = 1 To lastRow.Columns.count
            If Trim(CStr(lastRow.Cells(1, col).Value)) <> "" Then
                lastRow.Cells(1, col).EntireRow.Insert
                'Cut last row and paste to second last
                lastRow.Cut Destination:=table.ListRows(table.ListRows.count - 1).Range
                Exit For
            End If
        Next col
    End If

    'Populate last row with the form data
    Set lastRow = table.ListRows(table.ListRows.count).Range
    Range("E7:E10").Copy
    lastRow.PasteSpecial Transpose:=True
    Range("E7").Select
    Application.CutCopyMode = False

Hope it helps someone out there.

I'd set up your HTML like so:

<img src="../images/bottle.jpg" alt="bottle" class="thumbnails" id="bottle" />

Then use the following code:

<script>
var images = document.getElementsByTagName("img");
for(var i = 0; i < images.length; i++) {
    var image = images[i];
    image.onclick = function(event) {
         window.location.href = this.id + '.html';
    };
}
</script>

That assigns an onclick event handler to every image on the page (this may not be what you want, you can limit it further if necessary) that changes the current page to the value of the images id attribute plus the .html extension. It's essentially the pure Javascript implementation of @JanPöschko's jQuery answer.

Assuming that those are Strings, use the convenient static method sort…

 java.util.Collections.sort(listOfCountryNames)

As I found the default Bootstrap <hr/> size unsightly, here's some simple HTML and CSS to balance out the element visually:

HTML:

<hr class="half-rule"/>

CSS:

.half-rule { 
    margin-left: 0;
    text-align: left;
    width: 50%;
 }

I usually test the result of docker images -q (as in this script):

if [[ "$(docker images -q myimage:mytag 2> /dev/null)" == "" ]]; then
  # do something
fi

But since docker images only takes REPOSITORY as parameter, you would need to grep on tag, without using -q.

docker images takes tags now (docker 1.8+) [REPOSITORY[:TAG]]

The other approach mentioned below is to use docker inspect.
But with docker 17+, the syntax for images is: docker image inspect (on an non-existent image, the exit status will be non-0)

As noted by iTayb in the comments:

• The docker images -q method can get really slow on a machine with lots of images. It takes 44s to run on a 6,500 images machine.
• The docker image inspect returns immediately.

The mod_authz_host directives need to be inside a <Location> or <Directory> block but I've used the former within <VirtualHost> like so for Apache 2.2:

<VirtualHost *:8080>
    <Location />
    Order deny,allow
    Deny from all
    Allow from 127.0.0.1
    </Location>

    ...
</VirtualHost>

Reference: https://askubuntu.com/questions/262981/how-to-install-mod-authz-host-in-apache

Put the identity element before the authentication element

For any executable file, you can run your program using cmd with "c" parameter:

cmd /c "your program address"\"YourFileName".bat  

(->if it's a batch file!) As a final solution, I suggest that you create a .cmd file and put this command in it:

cmd /c "your program address"\"YourFileName".bat
exit

Now just run this .cmd file.

adapter.setNotifyDataChanged()

should do the trick.

In my machine which is ubuntu 14.04 with python 2.7 installed, if I go here,

/usr/local/lib/python2.7/dist-packages/nltk/

there is a file called

VERSION.

If I do a cat VERSION it prints 3.1, which is the NLTK version installed.

OFFSET     10 ROWS       -- skip 10 rows
FETCH NEXT 10 ROWS ONLY; -- take 10 rows

use this in the end of your select syntax. =)

If you are experiencing this problem when using Docker be sure to map the correct port numbers. If you map port 81:80 when running docker (or through docker-compose.yml), your nginx must listen on port 80 not 81, because docker does the mapping already.

I spent quite some time on this issue myself, so hope it can be to some help for future googlers.

dochoffiday's answer is a great starting point, but for me it did not cut it (the CSS part needed a buff) so I made a modified version with several improvements.

See it in action, then come back for the description.

JavaScript

(function ($) {
    $.fn.styleTable = function (options) {
        var defaults = {
            css: 'ui-styled-table'
        };
        options = $.extend(defaults, options);

        return this.each(function () {
            $this = $(this);
            $this.addClass(options.css);

            $this.on('mouseover mouseout', 'tbody tr', function (event) {
                $(this).children().toggleClass("ui-state-hover",
                                               event.type == 'mouseover');
            });

            $this.find("th").addClass("ui-state-default");
            $this.find("td").addClass("ui-widget-content");
            $this.find("tr:last-child").addClass("last-child");
        });
    };
})(jQuery);

Differences with the original version:

• the default CSS class has been changed to ui-styled-table (it sounds more consistent)
• the .live call was replaced with the recommended .on for jQuery 1.7 upwards
• the explicit conditional has been replaced by .toggleClass (a terser equivalent)
• code that sets the misleadingly-named CSS class first on table cells has been removed
• the code that dynamically adds .last-child to the last table row is necessary to fix a visual glitch on Internet Explorer 7 and Internet Explorer 8; for browsers that support :last-child it is not necessary

CSS

/* Internet Explorer 7: setting "separate" results in bad visuals; all other browsers work fine with either value. */
/* If set to "separate", then this rule is also needed to prevent double vertical borders on hover:
table.ui-styled-table tr * + th, table.ui-styled-table tr * + td  { border-left-width: 0px !important; } */
table.ui-styled-table { border-collapse: collapse; }

/* Undo the "bolding" that jQuery UI theme may cause on hovered elements
/* Internet Explorer 7: does not support "inherit", so use a MS proprietary expression along with an Internet Explorer <= 7 targeting hack
        to make the visuals consistent across all supported browsers */
table.ui-styled-table td.ui-state-hover {
    font-weight: inherit;
    *font-weight: expression(this.parentNode.currentStyle['fontWeight']);
}

/* Initally remove bottom border for all cells. */
table.ui-styled-table th, table.ui-styled-table td { border-bottom-width: 0px !important; }

/* Hovered-row cells should show bottom border (will be highlighted) */
table.ui-styled-table tbody tr:hover th,
table.ui-styled-table tbody tr:hover td
{ border-bottom-width: 1px !important; }

/* Remove top border if the above row is being hovered to prevent double horizontal borders. */
table.ui-styled-table tbody tr:hover + tr th,
table.ui-styled-table tbody tr:hover + tr td
{ border-top-width: 0px !important; }

/* Last-row cells should always show bottom border (not necessarily highlighted if not hovered). */
/* Internet Explorer 7, Internet Explorer 8: selector dependent on CSS classes because of no support for :last-child */
table.ui-styled-table tbody tr.last-child th,
table.ui-styled-table tbody tr.last-child td
{ border-bottom-width: 1px !important; }

/* Last-row cells should always show bottom border (not necessarily highlighted if not hovered). */
/* Internet Explorer 8 BUG: if these (unsupported) selectors are added to a rule, other selectors for that rule will stop working as well! */
/* Internet Explorer 9 and later, Firefox, Chrome: make sure the visuals are working even without the CSS classes crutch. */
table.ui-styled-table tbody tr:last-child th,
table.ui-styled-table tbody tr:last-child td
{ border-bottom-width: 1px !important; }

Notes

I have tested this on Internet Explorer 7 and upwards, Firefox 11 and Google Chrome 18 and confirmed that it works perfectly. I have not tested reasonably earlier versions of Firefox and Chrome or any version of Opera; however, those browsers are well-known for good CSS support and since we are not using any bleeding-edge functionality here I assume it will work just fine there as well.

If you are not interested in Internet Explorer 7 support there is one CSS attribute (introduced with the star hack) that can go.

If you are not interested in Internet Explorer 8 support either, the CSS and JavaScript related to adding and targeting the last-child CSS class can go as well.

This is what I did to achieve image rendering in DEBUG = False mode in Python 3.6 with Django 1.11

from django.views.static import serve
urlpatterns = [
url(r'^media/(?P<path>.*)$', serve,{'document_root': settings.MEDIA_ROOT}),
# other paths
]

Unfortunately:

• It seems you can not reference a single item from an array in values/arrays.xml with XML. Of course you can in Java, but not XML. There's no information on doing so in the Android developer reference, and I could not find any anywhere else.

• It seems you can't use an array as a key in the preferences layout. Each key has to be a single value with it's own key name.

What I want to accomplish: I want to be able to loop through the 17 preferences, check if the item is checked, and if it is, load the string from the string array for that preference name.

Here's the code I was hoping would complete this task:

SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(getBaseContext());  
ArrayAdapter<String> itemsArrayList = new ArrayAdapter<String>(getBaseContext(),   android.R.layout.simple_list_item_1);  
String[] itemNames = getResources().getStringArray(R.array.itemNames_array);  


for (int i = 0; i < 16; i++) {  
    if (prefs.getBoolean("itemKey[i]", true)) {  
        itemsArrayList.add(itemNames[i]);  
    }  
} 

What I did:

• I set a single string for each of the items, and referenced the single strings in the . I use the single string reference for the preferences layout checkbox titles, and the array for my loop.

• To loop through the preferences, I just named the keys like key1, key2, key3, etc. Since you reference a key with a string, you have the option to "build" the key name at runtime.

Here's the new code:

for (int i = 0; i < 16; i++) {  
        if (prefs.getBoolean("itemKey" + String.valueOf(i), true)) {  
        itemsArrayList.add(itemNames[i]);  
    }  
}

There is no extra backslash, it's just formatted that way in the interactive environment. Try:

print string

Then you can see that there really is no extra backslash.

If you want to compare with empty string without worrying about null values you can do the following.

if ("".equals(text))

Ultimately you should do what what you believe is clearest. Most programmers assume "" means empty string, not a string someone forgot to put anything into.

If you think there is a performance advantage, you should test it. If you don't think its worth testing for yourself, its a good indication it really isn't worth it.

It sounds like to you try to solve a problem which was solved when the language was designed more than 15 years ago.

You can union the queries as long as the columns match.

SELECT name,
       games,
       goals
FROM   tblMadrid
WHERE  id = 1
UNION ALL
SELECT name,
       games,
       goals
FROM   tblBarcelona
WHERE  id = 2 

A hardware or software flag. In multi tasking systems , a semaphore is as variable with a value that indicates the status of a common resource.A process needing the resource checks the semaphore to determine the resources status and then decides how to proceed.

I try mimetypes library first. If it's not working, I use python-magic libary instead.

import mimetypes
def guess_type(filename, buffer=None):
mimetype, encoding = mimetypes.guess_type(filename)
if mimetype is None:
    try:
        import magic
        if buffer:
            mimetype = magic.from_buffer(buffer, mime=True)
        else:
            mimetype = magic.from_file(filename, mime=True)
    except ImportError:
        pass
return mimetype

Along the lines of the HTTP Proxy answers, this can also happen due to a VPN connection. Disconnecting my VPN connection solved it for me.

Try adding this module, pretty simple, just launches Access, opens the database, sets the "Compact on Close" option to "True", then quits.

Syntax to auto-compact:

acCompactRepair "C:\Folder\Database.accdb", True

To return to default*:

acCompactRepair "C:\Folder\Database.accdb", False

*not necessary, but if your back end database is >1GB this can be rather annoying when you go into it directly and it takes 2 minutes to quit!

EDIT: added option to recurse through all folders, I run this nightly to keep databases down to a minimum.

I do wonder if perhaps you should iterate over the exploded HTTP_X_FORWARDED_FOR in reverse order, since my experience has been that the user's IP address ends up at the end of the comma-separated list, so starting at the start of the header, you're more likely to get the ip address of one of the proxies returned, which could potentially still allow session hijacking as many users may come through that proxy.

You can use json_decode(Your variable Name):

json_decode($result)

I was getting value from Model.where a column has value like this way

{"dayList":[
            {"day":[1,2,3,4],"time":[{"in_time":"10:00"},{"late_time":"15:00"},{"out_time":"16:15"}]
             },
             {"day":[5,6,7],"time":[{"in_time":"10:00"},{"late_time":"15:00"},{"out_time":"16:15"}]}
           ]
}

so access this value form model. you have to use this code.

$dayTimeListObject = json_decode($settingAttendance->bio_attendance_day_time,1);

 foreach ( $dayTimeListObject['dayList'] as $dayListArr)
 {
     foreach ( $dayListArr['day'] as $dayIndex)
     {
         if( $dayIndex == Date('w',strtotime('2020-02-11')))
         {
             $dayTimeList= $dayListArr['time'];
         }
     }
 }

 return $dayTimeList[2]['out_time'] ;

You can also define caste in your Model file.

 protected $casts = [
    'your-column-name' => 'json'
  ];

so after this no need of this line .

$dayTimeListObject = json_decode($settingAttendance->bio_attendance_day_time,1);

you can directly access this code.

$settingAttendance->bio_attendance_day_time

In C++ a class with at least one pure virtual function is called abstract class. You can not create objects of that class, but may only have pointers or references to it.

If you are deriving from an abstract class, then make sure you override and define all pure virtual functions for your class.

From your snippet Your class AliceUniversity seems to be an abstract class. It needs to override and define all the pure virtual functions of the classes Graduate and UniversityGraduate.

Pure virtual functions are the ones with = 0; at the end of declaration.

Example: virtual void doSomething() = 0;

For a specific answer, you will need to post the definition of the class for which you get the error and the classes from which that class is deriving.

The solution given by Albert works well as long as the provided function is invoked infrequently and is only used for arrays of modest size, otherwise it is egregiously inefficient. Here is an enhanced vanilla JavaScript solution that works for both Node and browsers and has the following advantages:

• Works efficiently for all octet array sizes

• Generates no intermediate throw-away strings

• Supports 4-byte characters on modern JS engines (otherwise "?" is substituted)

var utf8ArrayToStr = (function () {
    var charCache = new Array(128);  // Preallocate the cache for the common single byte chars
    var charFromCodePt = String.fromCodePoint || String.fromCharCode;
    var result = [];

    return function (array) {
        var codePt, byte1;
        var buffLen = array.length;

        result.length = 0;

        for (var i = 0; i < buffLen;) {
            byte1 = array[i++];

            if (byte1 <= 0x7F) {
                codePt = byte1;
            } else if (byte1 <= 0xDF) {
                codePt = ((byte1 & 0x1F) << 6) | (array[i++] & 0x3F);
            } else if (byte1 <= 0xEF) {
                codePt = ((byte1 & 0x0F) << 12) | ((array[i++] & 0x3F) << 6) | (array[i++] & 0x3F);
            } else if (String.fromCodePoint) {
                codePt = ((byte1 & 0x07) << 18) | ((array[i++] & 0x3F) << 12) | ((array[i++] & 0x3F) << 6) | (array[i++] & 0x3F);
            } else {
                codePt = 63;    // Cannot convert four byte code points, so use "?" instead
                i += 3;
            }

            result.push(charCache[codePt] || (charCache[codePt] = charFromCodePt(codePt)));
        }

        return result.join('');
    };
})();

To check for the existence of images, exif_imagetype should be preferred over getimagesize, as it is much faster.

To suppress the E_NOTICE, just prepend the error control operator (@).

if (@exif_imagetype($filename)) {
  // Image exist
}

As a bonus, with the returned value (IMAGETYPE_XXX) from exif_imagetype we could also get the mime-type or file-extension with image_type_to_mime_type / image_type_to_extension.

Nobody answered with regular for loop? Sometimes I find it more readable and prefer for over foreach
So here it is:

$array = array('key1' => 'value1', 'key2' => 'value2'); 

$keys = array_keys($array);

for($i=0; $i < count($keys); ++$i) {
    echo $keys[$i] . ' ' . $array[$keys[$i]] . "\n";
}

/*
  prints:
  key1 value1
  key2 value2
*/

Updated Answer

If you are using the following Windows versions or later: Windows Server 2012, Windows Server 2012 R2, or Windows 8.1 then MakeCert is now deprecated, and Microsoft recommends using the PowerShell Cmdlet New-SelfSignedCertificate.

If you're using an older version such as Windows 7, you'll need to stick with MakeCert or another solution. Some people suggest the Public Key Infrastructure Powershell (PSPKI) Module.

Original Answer

While you can create a self-signed code-signing certificate (SPC - Software Publisher Certificate) in one go, I prefer to do the following:

Creating a self-signed certificate authority (CA)

makecert -r -pe -n "CN=My CA" -ss CA -sr CurrentUser ^
         -a sha256 -cy authority -sky signature -sv MyCA.pvk MyCA.cer

(^ = allow batch command-line to wrap line)

This creates a self-signed (-r) certificate, with an exportable private key (-pe). It's named "My CA", and should be put in the CA store for the current user. We're using the SHA-256 algorithm. The key is meant for signing (-sky).

The private key should be stored in the MyCA.pvk file, and the certificate in the MyCA.cer file.

Importing the CA certificate

Because there's no point in having a CA certificate if you don't trust it, you'll need to import it into the Windows certificate store. You can use the Certificates MMC snapin, but from the command line:

certutil -user -addstore Root MyCA.cer

Creating a code-signing certificate (SPC)

makecert -pe -n "CN=My SPC" -a sha256 -cy end ^
         -sky signature ^
         -ic MyCA.cer -iv MyCA.pvk ^
         -sv MySPC.pvk MySPC.cer

It is pretty much the same as above, but we're providing an issuer key and certificate (the -ic and -iv switches).

We'll also want to convert the certificate and key into a PFX file:

pvk2pfx -pvk MySPC.pvk -spc MySPC.cer -pfx MySPC.pfx

If you want to protect the PFX file, add the -po switch, otherwise PVK2PFX creates a PFX file with no passphrase.

Using the certificate for signing code

signtool sign /v /f MySPC.pfx ^
              /t http://timestamp.url MyExecutable.exe

(See why timestamps may matter)

If you import the PFX file into the certificate store (you can use PVKIMPRT or the MMC snapin), you can sign code as follows:

signtool sign /v /n "Me" /s SPC ^
              /t http://timestamp.url MyExecutable.exe

Some possible timestamp URLs for signtool /t are:

• http://timestamp.verisign.com/scripts/timstamp.dll
• http://timestamp.globalsign.com/scripts/timstamp.dll
• http://timestamp.comodoca.com/authenticode

• signtool
• makecert
• pvk2pfx

Downloads

For those who are not .NET developers, you will need a copy of the Windows SDK and .NET framework. A current link is available here: SDK & .NET (which installs makecert in C:\Program Files\Microsoft SDKs\Windows\v7.1). Your mileage may vary.

MakeCert is available from the Visual Studio Command Prompt. Visual Studio 2015 does have it, and it can be launched from the Start Menu in Windows 7 under "Developer Command Prompt for VS 2015" or "VS2015 x64 Native Tools Command Prompt" (probably all of them in the same folder).

Hi~I found a solution which is much better,from: https://gist.github.com/ikew0ng/8297033

    /**
 * Remove all entries from the backStack of this fragmentManager.
 *
 * @param fragmentManager the fragmentManager to clear.
 */
private void clearBackStack(FragmentManager fragmentManager) {
    if (fragmentManager.getBackStackEntryCount() > 0) {
        FragmentManager.BackStackEntry entry = fragmentManager.getBackStackEntryAt(0);
        fragmentManager.popBackStack(entry.getId(), FragmentManager.POP_BACK_STACK_INCLUSIVE);
    }
}

This works for me

Move your .htaccess file to root folder (locate before application folder in my case)

RewriteEngine on
RewriteBase /yourProjectFolder
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php/$0 [PT,L]

Mine config.php looks like this (application/config/config.php)

$config['base_url'] = "";
$config['index_page'] = "index.php";
$config['uri_protocol'] = "AUTO";

Let me know if its working for you guys too ! Cheers !

An easier way that works regardless of the OS is to do

git rm -r --cached .
git add .
git commit -m "Drop files from .gitignore"

You basically remove and re-add all files, but git add will ignore the ones in .gitignore.

Using the --cached option will keep files in your filesystem, so you won't be removing files from your disk.

Note: Some pointed out in the comments that you will lose the history of all your files. I tested this with git 2.27.0 on MacOS and it is not the case. If you want to check what is happening, check your git diff HEAD~1 before you push your commit.

Puts the error message on top.

      position:relative; margin-top:40px; 
 } 

 #myoptions-error{ 
     position:absolute; 
     top: -25px; 
  } 

 </style> 

 <div class="radio-group">

 <input type="radio" name="myoptions" value="red"> Red<br /> 
 <input type="radio" name="myoptions" value="green"> Green </div>
 </div><!-- end radio-group -->

Supplemental answer

Here is how the standard keyboard behaves for each of these input types.

See this answer for more details.

First,

1. always define certificates with CURLOPT_CAPATH option,

2. decide how your POSTed data will be transfered.

1 Certificates

By default:

• CURLOPT_SSL_VERIFYHOST == 2 which "checks the existence of a common name and also verify that it matches the hostname provided" and

• CURLOPT_VERIFYPEER == true which "verifies the peer's certificate".

So, all you have to do is:

const CAINFO = SERVER_ROOT . '/registry/cacert.pem';
...
\curl_setopt($ch, CURLOPT_CAINFO, self::CAINFO);

taken from a working class where SERVER_ROOT is a constant defined during application bootstraping like in a custom classloader, another class etc.

Forget things like \curl_setopt($handler, CURLOPT_SSL_VERIFYHOST, 0); or \curl_setopt($handler, CURLOPT_SSL_VERIFYPEER, 0);.

Find cacert.pem there as seen in this question.

2 POST modes

There are actually 2 modes when posting data:

• the data is transfered with Content-Type header set to multipart/form-data or,

• the data is a urlencoded string with application/x-www-form-urlencoded encoding.

In the first case you pass an array while in the second you pass a urlencoded string.

multipart/form-data ex.:

$fields = array('a' => 'sth', 'b' => 'else');
$ch = \curl_init();
\curl_setopt($ch, CURLOPT_POST, 1);
\curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);

application/x-www-form-urlencoded ex.:

$fields = array('a' => 'sth', 'b' => 'else');
$ch = \curl_init();
\curl_setopt($ch, CURLOPT_POST, 1);
\curl_setopt($ch, CURLOPT_POSTFIELDS, \http_build_query($fields));

http_build_query:

Test it at your command line as

user@group:$ php -a
php > $fields = array('a' => 'sth', 'b' => 'else');
php > echo \http_build_query($fields);
a=sth&b=else

The other end of the POST request will define the appropriate mode of connection.

The answer is opinion. I worked in a lot of projects and being testmanager and issuemanager and all different roles and the descriptions in various books differ so here is my variation:

functional-testing: take the business requirements and test all of it good and thorougly from a functional viewpoint.

acceptance-testing: the "paying" customer does the testing he likes to do so that he can accept the product delivered. It depends on the customer but usually the tests are not as thorough as the functional-testing especially if it is an in-house project because the stakeholders review and trust the test results done in earlier test phases.

As I said this is my viewpoint and experience. The functional-testing is systematic and the acceptance-testing is rather the business department testing the thing.

One thing that you need to be aware of when reflecting on private members is that if your application is running in medium trust (as, for instance, when you are running on a shared hosting environment), it won't find them -- the BindingFlags.NonPublic option will simply be ignored.

Cookie

• is a small amount of data saved in the browser (client-side)

• can be set from PHP with setcookie and then will be sent to the client's browser (HTTP response header Set-cookie)

• can be set directly client-side in Javascript: document.cookie = 'foo=bar';

• if no expiration date is set, by default, it will expire when the browser is closed.
  Example: go on http://example.com, open the Console, do document.cookie = 'foo=bar';. Close the tab, reopen the same website, open the Console, do document.cookie: you will see foo=bar is still there. Now close the browser and reopen it, re-visit the same website, open the Console ; you will see document.cookie is empty.

• you can also set a precise expiration date other than "deleted when browser is closed".

• the cookies that are stored in the browser are sent to the server in the headers of every request of the same website (see Cookie). You can see this for example with Chrome by opening Developer tools > Network, click on the request, see Headers:

  

• can be read client-side with document.cookie

• can be read server-side with $_COOKIE['foo']

• Bonus: it can also be set/get with another language than PHP. Example in Python with "bottle" micro-framework (see also here):

  from bottle import get, run, request, response
  @get('/')
  def index():
      if request.get_cookie("visited"):
          return "Welcome back! Nice to see you again"
      else:
          response.set_cookie("visited", "yes")
          return "Hello there! Nice to meet you"
  run(host='localhost', port=8080, debug=True, reloader=True)
  

Session

• is some data relative to a browser session saved server-side

• each server-side language may implement it in a different way

• in PHP, when session_start(); is called:

  • a random ID is generated by the server, e.g. jo96fme9ko0f85cdglb3hl6ah6
  • a file is saved on the server, containing the data: e.g. /var/lib/php5/sess_jo96fme9ko0f85cdglb3hl6ah6

  • the session ID is sent to the client in the HTTP response headers, using the traditional cookie mechanism detailed above: Set-Cookie: PHPSESSID=jo96fme9ko0f85cdglb3hl6ah6; path=/:

    

    (it can also be be sent via the URL instead of cookie but not the default behaviour)

  • you can see the session ID on client-side with document.cookie:

    

• the PHPSESSID cookie is set with no expiration date, thus it will expire when the browser is closed. Thus "sessions" are not valid anymore when the browser is closed / reopened.

• can be set/read in PHP with $_SESSION

• the client-side does not see the session data but only the ID: do this in index.php:

  <?php
  session_start();
  $_SESSION["abc"]="def";
  ?>
  

  The only thing that is seen on client-side is (as mentioned above) the session ID:

  

• because of this, session is useful to store data that you don't want to be seen or modified by the client

• you can totally avoid using sessions if you want to use your own database + IDs and send an ID/token to the client with a traditional Cookie

Try the Currency Format Specifier ("C"). It automatically takes the current UI culture into account and displays currency values accordingly.

You can use it with either String.Format or the overloaded ToString method for a numeric type.

For example:

double value = 12345.6789;
Console.WriteLine(value.ToString("C", CultureInfo.CurrentCulture));

Console.WriteLine(value.ToString("C3", CultureInfo.CurrentCulture));

Console.WriteLine(value.ToString("C3", CultureInfo.CreateSpecificCulture("da-DK")));

// The example displays the following output on a system whose
// current culture is English (United States):
//       $12,345.68
//       $12,345.679
//       kr 12.345,679

To check if the value exists:

[#if userName??]
   Hi ${userName}, How are you?
[/#if]

Or with the standard freemarker syntax:

<#if userName??>
   Hi ${userName}, How are you?
</#if>

To check if the value exists and is not empty:

<#if userName?has_content>
    Hi ${userName}, How are you?
</#if>

Table variable

declare @listOfIDs table (id int);
insert @listOfIDs(id) values(1),(2),(3);    

select *
from TabA
where TabA.ID in (select id from @listOfIDs)

or

declare @listOfIDs varchar(1000);
SET @listOfIDs = ',1,2,3,'; --in this solution need put coma on begin and end

select *
from TabA
where charindex(',' + CAST(TabA.ID as nvarchar(20)) + ',', @listOfIDs) > 0

As everyone else have already said, primary keys are automatically indexed.

Creating more indexes on the primary key column only makes sense when you need to optimize a query that uses the primary key and some other specific columns. By creating another index on the primary key column and including some other columns with it, you may reach the desired optimization for a query.

For example you have a table with many columns but you are only querying ID, Name and Address columns. Taking ID as the primary key, we can create the following index that is built on ID but includes Name and Address columns.

CREATE NONCLUSTERED INDEX MyIndex
ON MyTable(ID)
INCLUDE (Name, Address)

So, when you use this query:

SELECT ID, Name, Address FROM MyTable WHERE ID > 1000

SQL Server will give you the result only using the index you've created and it'll not read anything from the actual table.

Another VBA way

Public Function GetColumnName(TargetCell As Range) As String
    GetColumnName = Split(CStr(TargetCell.Cells(1, 1).Address), "$")(1)
End Function

Same issue on Server 2016, IIS 10, 500.19 error. I installed the redirect module and it worked. I do not know why this was not included by default.

https://www.iis.net/downloads/microsoft/url-rewrite#additionalDownloads

To be clear it looks like the web.config from IIS 7 will work, or is designed to work, but the lack of this module gives the really odd and unhelpful error. Googling takes you to a Microsoft page which insists that your site is corrupted or your web.config is corrupted. Neither seems to be the case.

That unhelpful page is here: https://support.microsoft.com/en-us/kb/942055

If you deal regularly with Attributes in Reflection, it is very, very practical to define some extension methods. You will see that in many projects out there. This one here is one I often have:

public static bool HasAttribute<T>(this ICustomAttributeProvider provider) where T : Attribute
{
  var atts = provider.GetCustomAttributes(typeof(T), true);
  return atts.Length > 0;
}

which you can use like typeof(Foo).HasAttribute<BarAttribute>();

Other projects (e.g. StructureMap) have full-fledged ReflectionHelper classes that use Expression trees to have a fine syntax to identity e.g. PropertyInfos. Usage then looks like that:

ReflectionHelper.GetProperty<Foo>(x => x.MyProperty).HasAttribute<BarAttribute>()
