Programs & Examples On #Delay load

I recently hit this issue, the app would run fine on the developer machines and select others machines but not on recently installed machines. It turned out that the machines it did work on had the Visual C++ 11 Runtime installed while the freshly installed machines didn't. Adding the Visual C++ 11 Runtime redistributable to the app installer fixed the issue...

In your case, expand columns of that database in the object explorer. Drag the columns in to the query area.

And then just delete one or two columns which you don't want and then run it. I'm open to any suggestions easier than this.

You could use this jQuery plugin waitForImage or you could put you images into an hidden div or (width:0 and height:0) and use onload event on images.

If you only have like 2-3 images you can bind events and trigger them in a chain so after every image you can do some code.

I know this is old and answered but I recently had to implement this and decided to make 2 simple jQuery plugins that might help for those interested

usage:

// 1
$('.container').toggleAttr('aria-hidden', "true");
// 2
$('.container').toggleAttrVal('aria-hidden', "true", "false");

1 - Toggles the entire attribute regardless if the original value doesn't match the one you provided.

2 - Toggles the value of the attribute between the 2 provided values.

 // jquery toggle whole attribute
  $.fn.toggleAttr = function(attr, val) {
    var test = $(this).attr(attr);
    if ( test ) { 
      // if attrib exists with ANY value, still remove it
      $(this).removeAttr(attr);
    } else {
      $(this).attr(attr, val);
    }
    return this;
  };

  // jquery toggle just the attribute value
  $.fn.toggleAttrVal = function(attr, val1, val2) {
    var test = $(this).attr(attr);
    if ( test === val1) {
      $(this).attr(attr, val2);
      return this;
    }
    if ( test === val2) {
      $(this).attr(attr, val1);
      return this;
    }
    // default to val1 if neither
    $(this).attr(attr, val1);
    return this;
  };

This is how you would use it in the original example:

$(".list-toggle").click(function() {
    $(".list-sort").toggleAttr('colspan', 6);
});

Recently I learned of the following syntax:

DELETE (SELECT *
        FROM productfilters pf
        INNER JOIN product pr
            ON pf.productid = pr.id
        WHERE pf.id >= 200
            AND pr.NAME = 'MARK')

I think it looks much cleaner then other proposed code.

As Dan said correctly,

If you see this:

npm ERR! [email protected] start: `react-scripts start`
npm ERR! spawn ENOENT

It just means something went wrong when dependencies were installed the first time.

But I got something slightly different because running npm install -g npm@latest to update npm might sometimes leave you with this error:

npm ERR! code ETARGET
npm ERR! notarget No matching version found for npm@lates
npm ERR! notarget In most cases you or one of your dependencies are requesting
npm ERR! notarget a package version that doesn't exist.

so, instead of running npm install -g npm@latest, I suggest running the below steps:

 npm i -g npm //which will also update npm
 rm -rf node_modules/ && npm cache clean // to remove the existing modules and clean the cache.
 npm install //to re-install the project dependencies.

This should get you back on your feet.

my friend by this u are not getting height of image stored in db.but you are getting view height.for getting height of image u have to create bitmap from db,s image.and than u can fetch height and width of imageview

For just reading the last element of a slice:

sl[len(sl)-1]

For removing it:

sl = sl[:len(sl)-1]

See this page about slice tricks

You can use e.preventDefault() which will stop the current operation.

than you can do$("#form").submit();

 $('#form').submit(function (e)
{
    return !!e.submit;
});
if(blabla...)
{...
}
else
{
    $('#form').submit(
    {
        submit: true
    });
}

1) What is an API?

API is a contract. A promise to perform described services when asked in specific ways.

2) How is it used?

According to the rules specified in the contract. The whole point of an API is to define how it's used.

3) When and where is it used?

It's used when 2 or more separate systems need to work together to achieve something they can't do alone.

Here is the code that I used to hide the .php extension from the filename:

## hide .php extension
# To redirect /dir/foo.php to /dir/foo
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s([^.]+)\.php [NC]
RewriteRule ^ %1 [R=301,L,NC]

Note: R=301 is for permanent redirect and is recommended to use for SEO purpose. However if one wants just a temporary redirect replace it with just R

Don't worry about any performance differences, they're going to be minimal in this case normally.

Method 2 is preferable because

1. it doesn't require mutating a collection that exists outside the lambda expression,

2. it's more readable because the different steps that are performed in the collection pipeline are written sequentially: first a filter operation, then a map operation, then collecting the result (for more info on the benefits of collection pipelines, see Martin Fowler's excellent article),

3. you can easily change the way values are collected by replacing the Collector that is used. In some cases you may need to write your own Collector, but then the benefit is that you can easily reuse that.

JAXB is an ideal solution. But you do not necessarily need xsd and xjc for that. More often than not you don't have an xsd but you know what your xml is. Simply analyze your xml, e.g.,

<customer id="100">
    <age>29</age>
    <name>mkyong</name>
</customer>

Create necessary model class(es):

@XmlRootElement
public class Customer {

    String name;
    int age;
    int id;

    public String getName() {
        return name;
    }

    @XmlElement
    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    @XmlElement
    public void setAge(int age) {
        this.age = age;
    }

    public int getId() {
        return id;
    }

    @XmlAttribute
    public void setId(int id) {
        this.id = id;
    }

}

Try to unmarshal:

JAXBContext jaxbContext = JAXBContext.newInstance(Customer.class);
Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
Customer customer = (Customer) jaxbUnmarshaller.unmarshal(new File("C:\\file.xml"));

Check results, fix bugs!

The struct module mimics C structures. It takes more CPU cycles for a processor to read a 16-bit word on an odd address or a 32-bit dword on an address not divisible by 4, so structures add "pad bytes" to make structure members fall on natural boundaries. Consider:

struct {                   11
    char a;      012345678901
    short b;     ------------
    char c;      axbbcxxxdddd
    int d;
};

This structure will occupy 12 bytes of memory (x being pad bytes).

Python works similarly (see the struct documentation):

>>> import struct
>>> struct.pack('BHBL',1,2,3,4)
'\x01\x00\x02\x00\x03\x00\x00\x00\x04\x00\x00\x00'
>>> struct.calcsize('BHBL')
12

Compilers usually have a way of eliminating padding. In Python, any of =<>! will eliminate padding:

>>> struct.calcsize('=BHBL')
8
>>> struct.pack('=BHBL',1,2,3,4)
'\x01\x02\x00\x03\x04\x00\x00\x00'

Beware of letting struct handle padding. In C, these structures:

struct A {       struct B {
    short a;         int a;
    char b;          char b;
};               };

are typically 4 and 8 bytes, respectively. The padding occurs at the end of the structure in case the structures are used in an array. This keeps the 'a' members aligned on correct boundaries for structures later in the array. Python's struct module does not pad at the end:

>>> struct.pack('LB',1,2)
'\x01\x00\x00\x00\x02'
>>> struct.pack('LBLB',1,2,3,4)
'\x01\x00\x00\x00\x02\x00\x00\x00\x03\x00\x00\x00\x04'

There is no need to compute trigonometric functions. The simple code in C language is:

#include <math.h>
#define PIV2 M_PI+M_PI
#define C360 360.0000000000000000000
double difangrad(double x, double y)
{
double arg;

arg = fmod(y-x, PIV2);
if (arg < 0 )  arg  = arg + PIV2;
if (arg > M_PI) arg  = arg - PIV2;

return (-arg);
}
double difangdeg(double x, double y)
{
double arg;
arg = fmod(y-x, C360);
if (arg < 0 )  arg  = arg + C360;
if (arg > 180) arg  = arg - C360;
return (-arg);
}

let dif = a - b , in radians

dif = difangrad(a,b);

let dif = a - b , in degrees

dif = difangdeg(a,b);

difangdeg(180.000000 , -180.000000) = 0.000000
difangdeg(-180.000000 , 180.000000) = -0.000000
difangdeg(359.000000 , 1.000000) = -2.000000
difangdeg(1.000000 , 359.000000) = 2.000000

No sin, no cos, no tan,.... only geometry!!!!

in fact, you can, but not that way.

Sub MySub( Optional Byval Counter as Long=1 , Optional Byval Events as Boolean= True)

'code...

End Sub

And you can set the variables differently when calling the sub, or let them at their default values.

Extending Stuart Marks's answer, this can be done in a shorter way and without a concurrent map (if you don't need parallel streams):

public static <T> Predicate<T> distinctByKey(Function<? super T, ?> keyExtractor) {
    final Set<Object> seen = new HashSet<>();
    return t -> seen.add(keyExtractor.apply(t));
}

Then call:

persons.stream().filter(distinctByKey(p -> p.getName());

This errors occurs when we use same method name for Jaxb2Marshaller for exemple:

    @Bean
    public Jaxb2Marshaller marshallerClient() {
        Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
        // this package must match the package in the <generatePackage> specified in
        // pom.xml
        marshaller.setContextPath("library.io.github.walterwhites.loans");

        return marshaller;
    }

And on other file

    @Bean
    public Jaxb2Marshaller marshallerClient() {
        Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
        // this package must match the package in the <generatePackage> specified in
        // pom.xml
        marshaller.setContextPath("library.io.github.walterwhites.client");

        return marshaller;
    }

Even It's different class, you should named them differently

Like Unix shells, PowerShell supports > redirects with most of the variations known from Unix, including 2>&1 (though weirdly, order doesn't matter - 2>&1 > file works just like the normal > file 2>&1).

Like most modern Unix shells, PowerShell also has a shortcut for redirecting both standard error and standard output to the same device, though unlike other redirection shortcuts that follow pretty much the Unix convention, the capture all shortcut uses a new sigil and is written like so: *>.

So your implementation might be:

& myjob.bat *>> $logfile

If you have to work with file-stream (so no physically saved PDF) like we do and you want to download the PDF without page-reload, the following function works for us:

HTML

<div id="download-helper-hidden-container" style="display:none">
     <form id="download-helper-form" target="pdf-download-output" method="post">
            <input type="hidden" name="downloadHelperTransferData" id="downloadHelperTransferData" />
     </form>
     <iframe id="pdf-helper-output" name="pdf-download-output"></iframe>
</div>

Javascript

var form = document.getElementById('download-helper-form');
$("#downloadHelperTransferData").val(transferData);
form.action = "ServerSideFunctionWhichWritesPdfBytesToResponse";
form.submit();

Due to the target="pdf-download-output", the response is written into the iframe and therefore no page reload is executed, but the pdf-response-stream is output in the browser as a download.

if echo $var | egrep -q '^[0-9]+$'; then
    # $var is a number
else
    # $var is not a number
fi

Dashes (-) have no significance other than making the number more readable, so you might as well include them.

Since we never know where our website visitors are coming from, we need to make phone numbers callable from anywhere in the world. For this reason the + sign is always necessary. The + sign is automatically converted by your mobile carrier to your international dialing prefix, also known as "exit code". This code varies by region, country, and sometimes a single country can use multiple codes, depending on the carrier. Fortunately, when it is a local call, dialing it with the international format will still work.

Using your example number, when calling from China, people would need to dial:

00-1-555-555-1212

And from Russia, they would dial

810-1-555-555-1212

The + sign solves this issue by allowing you to omit the international dialing prefix.

After the international dialing prefix comes the country code^(pdf), followed by the geographic code (area code), finally the local phone number.

Therefore either of the last two of your examples would work, but my recommendation is to use this format for readability:

<a href="tel:+1-555-555-1212">+1-555-555-1212</a>

Note: For numbers that contain a trunk prefix different from the country code (e.g. if you write it locally with brackets around a 0), you need to omit it because the number must be in international format.

Yes. You can use *args as a non-keyword argument. You will then be able to pass any number of arguments.

def manyArgs(*arg):
  print "I was called with", len(arg), "arguments:", arg

>>> manyArgs(1)
I was called with 1 arguments: (1,)
>>> manyArgs(1, 2, 3)
I was called with 3 arguments: (1, 2, 3)

As you can see, Python will unpack the arguments as a single tuple with all the arguments.

For keyword arguments you need to accept those as a separate actual argument, as shown in Skurmedel's answer.

I would like to present another answer to this as the currently accepted answer doesn't work for me (I use LibreOffice). This solution should work in Excel, LibreOffice and OpenOffice:

First, insert a new row at the beginning of the sheet. Within that row, define the names you need:

Then, in the menu bar, go to View -> Freeze Cells -> Freeze First Row. It'll look like this now:

Now whenever you scroll down in the document, the first row will be "pinned" to the top:

Your need to use the html/xhtml break character:

<br />

You can also disable SSL verification, (if the project does not require a high level of security other than login/password) by typing :

git config --global http.sslverify false

enjoy git :)

Commons Lang has it. Or you could throw an UnsupportedOperationException.

ok , i've solved it by creating a handler on the onCreate of the service , and calling the gps functions through there .

The code is as simple as this:

final handler=new Handler(Looper.getMainLooper()); 

And then to force running things on the UI, I call post on it.

I am not 100% certain, but I think this does what you want using prop.table. See mostly the last 3 lines. The rest of the code is just creating fake data.

set.seed(1234)

total_bill <- rnorm(50, 25, 3)
tip <- 0.15 * total_bill + rnorm(50, 0, 1)
sex <- rbinom(50, 1, 0.5)
smoker <- rbinom(50, 1, 0.3)
day <- ceiling(runif(50, 0,7))
time <- ceiling(runif(50, 0,3))
size <- 1 + rpois(50, 2)
my.data <- as.data.frame(cbind(total_bill, tip, sex, smoker, day, time, size))
my.data

my.table <- table(my.data$smoker)

my.prop <- prop.table(my.table)

cbind(my.table, my.prop)

"What's the use of using join()?" you say. Really, it's the same answer as "what's the use of closing files, since python and the OS will close my file for me when my program exits?".

It's simply a matter of good programming. You should join() your threads at the point in the code that the thread should not be running anymore, either because you positively have to ensure the thread is not running to interfere with your own code, or that you want to behave correctly in a larger system.

You might say "I don't want my code to delay giving an answer" just because of the additional time that the join() might require. This may be perfectly valid in some scenarios, but you now need to take into account that your code is "leaving cruft around for python and the OS to clean up". If you do this for performance reasons, I strongly encourage you to document that behavior. This is especially true if you're building a library/package that others are expected to utilize.

There's no reason to not join(), other than performance reasons, and I would argue that your code does not need to perform that well.

Some comments were asking how to save all of the IPython inputs at once. For %save magic in IPython, you can save all of the commands programmatically as shown below, to avoid the prompt message and also to avoid specifying the input numbers. currentLine = len(In)-1 %save -f my_session 1-$currentLine

The -f option is used for forcing file replacement and the len(IN)-1 shows the current input prompt in IPython, allowing you to save the whole session programmatically.

Looks like your IndexPartial action method has an argument which is a complex object. If you are passing a a lot of data (complex object), It might be a good idea to convert your action method to a HttpPost action method and use jQuery post to post data to that. GET has limitation on the query string value.

[HttpPost]
public PartialViewResult IndexPartial(DashboardViewModel m)
{
   //May be you want to pass the posted model to the parial view?
   return PartialView("_IndexPartial");
}

Your script should be

var url = "@Url.Action("IndexPartial","YourControllerName")";

var model = { Name :"Shyju", Location:"Detroit"};

$.post(url, model, function(res){
   //res contains the markup returned by the partial view
   //You probably want to set that to some Div.
   $("#SomeDivToShowTheResult").html(res);
});

Assuming Name and Location are properties of your DashboardViewModel class and SomeDivToShowTheResult is the id of a div in your page where you want to load the content coming from the partialview.

Sending complex objects?

You can build more complex object in js if you want. Model binding will work as long as your structure matches with the viewmodel class

var model = { Name :"Shyju", 
              Location:"Detroit", 
              Interests : ["Code","Coffee","Stackoverflow"]
            };

$.ajax({
    type: "POST",
    data: JSON.stringify(model),
    url: url,
    contentType: "application/json"
}).done(function (res) {
    $("#SomeDivToShowTheResult").html(res);
});

For the above js model to be transformed to your method parameter, Your View Model should be like this.

public class DashboardViewModel
{
  public string Name {set;get;}
  public string Location {set;get;}
  public List<string> Interests {set;get;}
}

And in your action method, specify [FromBody]

[HttpPost]
public PartialViewResult IndexPartial([FromBody] DashboardViewModel m)
{
    return PartialView("_IndexPartial",m);
}

Just simply use this Style of DataGridRow:

<DataGrid.RowStyle>
        <Style TargetType="DataGridRow">
            <Setter Property="IsEnabled" Value="{Binding RelativeSource={RelativeSource Self},Path=IsNewItem,Mode=OneWay}" />
        </Style>
</DataGrid.RowStyle>

I vote for this 2:

string currentActionName = ViewContext.RouteData.GetRequiredString("action");

and

string currentViewName = ((WebFormView)ViewContext.View).ViewPath;

You can retrive both physical name of current view and action that triggered it. It can be usefull in partial *.acmx pages to determine host container.

In Kotlin, if you refer the Button View with id then, enable/disable button as like

layout.xml

<Button
   android:id="@+id/btn_start"
   android:layout_width="100dp"
   android:layout_height="50dp"
   android:text="@string/start"
   android:layout_alignParentBottom="true"/>

activity.kt

  btn_start.isEnabled = true   //to enable button
  btn_start.isEnabled = false  //to disable button

Add yourself to the vboxsf group within the guest VM.

Solution 1

Run sudo adduser $USER vboxsf from terminal.
(On Suse it's sudo usermod --append --groups vboxsf $USER)

To take effect you should log out and then log in, or you may need to reboot.

Solution 2

Edit the file /etc/group (you will need root privileges). Look for the line vboxsf:x:999 and add at the end :yourusername -- use this solution if you don't have sudo.

To take effect you should log out and then log in, or you may need to reboot.

Also can be done from the environment variable:

export CURL_CA_BUNDLE=""

All you need:

table {
    border-collapse: separate;
    border-spacing: 0 1em;
}

That assumes you want a 1em vertical gap, and no horizontal gap. If you're doing this, you should probably also look at controlling your line-height.

Sort of weird that some of the answers people gave involve border-collapse: collapse, whose effect is the exact opposite of what the question asked for.

You can't call "printf" with a std::string in parameter. The "%s" is designed for C-style string : char* or char []. In C++ you can do like that :

#include <iostream>
std::cout << YourString << std::endl;

If you absolutely want to use printf, you can use the "c_str()" method that give a char* representation of your string.

printf("%s\n",YourString.c_str())

Usually the problem is not closing brackets (}) or missing semicolon (;)

You can use the File class to list the directories.

File file = new File("/path/to/directory");
String[] directories = file.list(new FilenameFilter() {
  @Override
  public boolean accept(File current, String name) {
    return new File(current, name).isDirectory();
  }
});
System.out.println(Arrays.toString(directories));

Update

Comment from the author on this post wanted a faster way, great discussion here: How to retrieve a list of directories QUICKLY in Java?

Basically:

1. If you control the file structure, I would try to avoid getting into that situation.
2. In Java NIO.2, you can use the directories function to return an iterator to allow for greater scaling. The directory stream class is an object that you can use to iterate over the entries in a directory.

Please create a custom TextView and use it :

public class CustomTextView extends TextView {

    public CapitalizedTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public void setText(CharSequence text, BufferType type) {
        if (text.length() > 0) {
            text = String.valueOf(text.charAt(0)).toUpperCase() + text.subSequence(1, text.length());
        }
        super.setText(text, type);
    }
}

You could install Charles - an HTTP proxy / HTTP monitor / Reverse Proxy that enables a developer to view all of the HTTP and SSL / HTTPS traffic between their machine and the Internet - on your PC or MAC.

Config steps:

• Let your phone and PC or MAC in a same LAN
• Launch Charles which you installed (default proxy port is 8888)
• Setup your phone's wifi configuration: set the ip of delegate to your PC or MAC's ip, port of delegate to 8888
• Lauch your app in your phone. And monitor http requests on Charles.

http://poi.apache.org/spreadsheet/quick-guide.html#CreateDateCells

CellStyle cellStyle = wb.createCellStyle();
CreationHelper createHelper = wb.getCreationHelper();
cellStyle.setDataFormat(
    createHelper.createDataFormat().getFormat("m/d/yy h:mm"));
cell = row.createCell(1);
cell.setCellValue(new Date());
cell.setCellStyle(cellStyle);

I agree with the last answer.But there is another way to solve this problem.You can download the package named future,such as pip install future.And in your .py file input this "from past.builtins import xrange".This method is for the situation that there are many xranges in your file.

You want the php function "asort":

http://php.net/manual/en/function.asort.php

it sorts the array, maintaining the index associations.

Edit: I've just noticed you're using a standard array (non-associative). if you're not fussed about preserving index associations, use sort():

http://php.net/manual/en/function.sort.php

Here's the example from my code. So I will read a text from 1st line to 3rd line using readLine() and then store to array variable and print into textfield using for-loop :

QFile file("file.txt");

    if(!file.open(QIODevice::ReadOnly | QIODevice::Text))
        return;

    QTextStream in(&file);
    QString line[3] = in.readLine();
    for(int i=0; i<3; i++)
    {
        ui->textEdit->append(line[i]);
    }

If you don't really need the mechanism, just specify a random flavor dimension in your build.gradle:

android { 
    ...
    flavorDimensions "default"
    ...
}

The usual technique for this is margin:auto

However, old IE doesn't grok this so one usually adds text-align: center to an outer containing element. You wouldn't think that would work but the same IE's that ignore auto also incorrectly apply the text align center to block level inner elements so things work out.

And this doesn't actually do a real float.

Try the HTML code: •

Which will appear as: •

DECLARE @intFlag INT
SET @intFlag = 1
WHILE (@intFlag <=5) 
BEGIN
    PRINT @intFlag
    SET @intFlag = @intFlag + 1
END
GO

This is the best solution I came up with taking hints from @Vinayak's answer. All the other solutions have different drawbacks.

First of all create a function like this.

void addClickEffect(View view)
{
    Drawable drawableNormal = view.getBackground();

    Drawable drawablePressed = view.getBackground().getConstantState().newDrawable();
    drawablePressed.mutate();
    drawablePressed.setColorFilter(Color.argb(50, 0, 0, 0), PorterDuff.Mode.SRC_ATOP);

    StateListDrawable listDrawable = new StateListDrawable();
    listDrawable.addState(new int[] {android.R.attr.state_pressed}, drawablePressed);
    listDrawable.addState(new int[] {}, drawableNormal);
    view.setBackground(listDrawable);
}

Explanation:

getConstantState().newDrawable() is used to clone the existing Drawable otherwise the same drawable will be used. Read more from here: Android: Cloning a drawable in order to make a StateListDrawable with filters

mutate() is used to make the Drawable clone not share its state with other instances of Drawable. Read more about it here: https://developer.android.com/reference/android/graphics/drawable/Drawable.html#mutate()

Usage:

You can pass any type of View (Button, ImageButton, View etc) as the parameter to the function and they will get the click effect applied to them.

addClickEffect(myButton);
addClickEffect(myImageButton);

Go has a foreach-like syntax. It supports arrays/slices, maps and channels.

Iterate over array or slice:

// index and value
for i, v := range slice {}

// index only
for i := range slice {}

// value only
for _, v := range slice {}

Iterate over a map:

// key and value
for key, value := range theMap {}

// key only
for key := range theMap {}

// value only
for _, value := range theMap {}

Iterate over a channel:

for v := range theChan {}

Iterating over a channel is equivalent to receiving from a channel until it is closed:

for {
    v, ok := <-theChan
    if !ok {
        break
    }
}

Use a DecimalFormat object with a format string of "0.#".

Yes. IE7+ supports attribute selectors:

input[type=radio]
input[type^=ra]
input[type*=d]
input[type$=io]

Element input with attribute type which contains a value that is equal to, begins with, contains or ends with a certain value.

Other safe (IE7+) selectors are:

• Parent > child that has: p > span { font-weight: bold; }
• Preceded by ~ element which is: span ~ span { color: blue; }

Which for <p><span/><span/></p> would effectively give you:

<p>
    <span style="font-weight: bold;">
    <span style="font-weight: bold; color: blue;">
</p>

I'm surprised that everyone else thinks it can't be done. CSS attribute selectors have been here for some time already. I guess it's time we clean up our .css files.

Self validated model

Your model should implement an interface IValidatableObject. Put your validation code in Validate method:

public class MyModel : IValidatableObject
{
    public string Title { get; set; }
    public string Description { get; set; }

    public IEnumerable<ValidationResult> Validate(ValidationContext validationContext)
    {
        if (Title == null)
            yield return new ValidationResult("*", new [] { nameof(Title) });

        if (Description == null)
            yield return new ValidationResult("*", new [] { nameof(Description) });
    }
}

Please notice: this is a server-side validation. It doesn't work on client-side. You validation will be performed only after form submission.

I wish I still had a link to the source that lead me in this direction, but this is the code that ended up working for me. By looking over the JavaDoc for X509TrustManager it looks like the way the TrustManagers work is by returning nothing on successful validation, otherwise throwing an exception. Thus, with a null implementation, it is treated as a successful validation. Then you remove all other implementations.

import javax.net.ssl.*;
import java.security.*;
import java.security.cert.X509Certificate;

public final class SSLUtil{

    private static final TrustManager[] UNQUESTIONING_TRUST_MANAGER = new TrustManager[]{
            new X509TrustManager() {
                public java.security.cert.X509Certificate[] getAcceptedIssuers(){
                    return null;
                }
                public void checkClientTrusted( X509Certificate[] certs, String authType ){}
                public void checkServerTrusted( X509Certificate[] certs, String authType ){}
            }
        };

    public  static void turnOffSslChecking() throws NoSuchAlgorithmException, KeyManagementException {
        // Install the all-trusting trust manager
        final SSLContext sc = SSLContext.getInstance("SSL");
        sc.init( null, UNQUESTIONING_TRUST_MANAGER, null );
        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
    }

    public static void turnOnSslChecking() throws KeyManagementException, NoSuchAlgorithmException {
        // Return it to the initial state (discovered by reflection, now hardcoded)
        SSLContext.getInstance("SSL").init( null, null, null );
    }

    private SSLUtil(){
        throw new UnsupportedOperationException( "Do not instantiate libraries.");
    }
}

When you think your git is messed up, you can use this command to do everything up-to-date.

git rm -r --cached .
git add .
git commit -am 'git cache cleared'
git push

Also to revert back last commit use this :

git reset HEAD^ --hard

For multiple files; note the newer "multiple" attribute for input:

Form:

@using (Html.BeginForm("FileImport","Import",FormMethod.Post, new {enctype = "multipart/form-data"}))
{
    <label for="files">Filename:</label>
    <input type="file" name="files" multiple="true" id="files" />
    <input type="submit"  />
}

Controller:

[HttpPost]
public ActionResult FileImport(IEnumerable<HttpPostedFileBase> files)
{
    return View();
}

When using promises they can be used in a promise chain. async=false will be deprecated so using promises is your best option.

function functABC() {
  return new Promise(function(resolve, reject) {
    $.ajax({
      url: 'myPage.php',
      data: {id: id},
      success: function(data) {
        resolve(data) // Resolve promise and go to then()
      },
      error: function(err) {
        reject(err) // Reject the promise and go to catch()
      }
    });
  });
}

functABC().then(function(data) {
  // Run this when your request was successful
  console.log(data)
}).catch(function(err) {
  // Run this when promise was rejected via reject()
  console.log(err)
})

For any one who looks for answer yet:

1.Add jackson-databind library to your build tools like Gradle or Maven

2.in your Code:

ObjectMapper mapper = new ObjectMapper();

List<Student> studentList = new ArrayList<>();

studentList = Arrays.asList(mapper.readValue(jsonStringArray, Student[].class));

If you do not want to use CURL, you could find some examples on stackoverflow, just like this one here: How do I send a POST request with PHP?. I would recommend you watch a few tutorials on how to use GET and POST methods within PHP or just take a look at the php.net manual here: httprequest::send. You can find a lot of tutorials: HTTP POST from PHP, without cURL and so on...

Since the question asked for either jQuery or vanilla JS, here's an answer with vanilla JS.

I've added some CSS to the demo below to change the button's font color to red when its aria-expanded is set to true

const button = document.querySelector('button');_x000D_
_x000D_
button.addEventListener('click', () => {_x000D_
  button.ariaExpanded = !JSON.parse(button.ariaExpanded);_x000D_
})

button[aria-expanded="true"] {_x000D_
  color: red;_x000D_
}

<button type="button" aria-expanded="false">Click me!</button>

As per Do a "git export" (like "svn export")?

You can use git checkout-index for that, this is a low level command, if you want to export everything, you can use -a,

git checkout-index -a -f --prefix=/destination/path/

To quote the man pages:

The final "/" [on the prefix] is important. The exported name is literally just prefixed with the specified string.

If you want to export a certain directory, there are some tricks involved. The command only takes files, not directories. To apply it to directories, use the 'find' command and pipe the output to git.

find dirname -print0 | git checkout-index --prefix=/path-to/dest/ -f -z --stdin

Also from the man pages:

Intuitiveness is not the goal here. Repeatability is.

Try disabling the extension Bundler & Minifier

If you set up a click binding in Knockout the event is passed as the second parameter. You can use the event to obtain the element that the click occurred on and perform whatever action you want.

Here is a fiddle that demonstrates: http://jsfiddle.net/jearles/xSKyR/

Alternatively, you could create your own custom binding, which will receive the element it is bound to as the first parameter. On init you could attach your own click event handler to do any actions you wish.

http://knockoutjs.com/documentation/custom-bindings.html

HTML

<div>
    <button data-bind="click: clickMe">Click Me!</button>
</div>

Js

var ViewModel = function() {
    var self = this;
    self.clickMe = function(data,event) {

      var target = event.target || event.srcElement;

      if (target.nodeType == 3) // defeat Safari bug
        target = target.parentNode;

      target.parentNode.innerHTML = "something";
    }
}

ko.applyBindings(new ViewModel());

First you need to download the particular jar from Oracle site (ojdbc.jar version 11.2.0.3)

if you download it to C:\filefolder

go to that directory in cmd prompt and provide the below command.It will install the dependency.Then you can build your project.

mvn install:install-file -DgroupId=com.oracle -DartifactId=ojdbc6 -Dpackaging=jar -Dversion=11.2.0.4.0 -Dfile=ojdbc6.jar -DgeneratePom=true

A typical best practice is not using long/int/short directly. Instead, according to specification of compilers and OS, wrap them into a header file to ensure they hold exactly the amount of bits that you want. Then use int8/int16/int32 instead of long/int/short. For example, on 32bit Linux, you could define a header like this

typedef char int8;
typedef short int16;
typedef int int32;
typedef unsigned int uint32;

There is a solution here : Add

/full /netfx at the end of the path!

This should clear almost all. You should only be left with SQL Server.

Unfortunately, no. Not with HTML and CSS. You need an a element to make a link, and you can't wrap an entire table row in one.

The closest you can get is linking every table cell. Personally I'd just link one cell and use JavaScript to make the rest clickable. It's good to have at least one cell that really looks like a link, underlined and all, for clarity anyways.

Here's a simple jQuery snippet to make all table rows with links clickable (it looks for the first link and "clicks" it)

$("table").on("click", "tr", function(e) {
    if ($(e.target).is("a,input")) // anything else you don't want to trigger the click
        return;

    location.href = $(this).find("a").attr("href");
});

if (empty($_FILES['cover_image']['name']))

Not sure that stretching a background image is possible. If you find that it's not possible, or not reliable in all of your target browsers, you could try using a stretched img tag with z-index set lower, and position set to absolute so that other content appears on top of it.

Let us know what you end up doing.

Edit: What I suggested is basically what's in gabriel's link. So try that :)

This is fairly easy to answer from the internet. Set system properties http.proxyHost and http.proxyPort. You can do this with System.setProperty(), or from the command line with the -D syntax.

You can use "group by" + "orderby". See LINQ 101 for details

var list = new List<string> {"a", "b", "a", "c", "a", "b"};
var q = from x in list
        group x by x into g
        let count = g.Count()
        orderby count descending
        select new {Value = g.Key, Count = count};
foreach (var x in q)
{
    Console.WriteLine("Value: " + x.Value + " Count: " + x.Count);
}

In response to this post (now deleted):

If you have a list of some custom objects then you need to use custom comparer or group by specific property.

Also query can't display result. Show us complete code to get a better help.

Based on your latest update:

You have this line of code:

group xx by xx into g

Since xx is a custom object system doesn't know how to compare one item against another. As I already wrote, you need to guide compiler and provide some property that will be used in objects comparison or provide custom comparer. Here is an example:

Note that I use Foo.Name as a key - i.e. objects will be grouped based on value of Name property.

There is one catch - you treat 2 objects to be duplicate based on their names, but what about Id ? In my example I just take Id of the first object in a group. If your objects have different Ids it can be a problem.

//Using extension methods
var q = list.GroupBy(x => x.Name)
            .Select(x => new {Count = x.Count(), 
                              Name = x.Key, 
                              ID = x.First().ID})
            .OrderByDescending(x => x.Count);

//Using LINQ
var q = from x in list
        group x by x.Name into g
        let count = g.Count()
        orderby count descending
        select new {Name = g.Key, Count = count, ID = g.First().ID};

foreach (var x in q)
{
    Console.WriteLine("Count: " + x.Count + " Name: " + x.Name + " ID: " + x.ID);
}

Since the issue of whitespace only comes up when exporting arrays, you can use the original var_export() for all other variable types. This function does the job, and, from the outside, works the same as var_export().

<?php

function var_export_min($var, $return = false) {
    if (is_array($var)) {
        $toImplode = array();
        foreach ($var as $key => $value) {
            $toImplode[] = var_export($key, true).'=>'.var_export_min($value, true);
        }
        $code = 'array('.implode(',', $toImplode).')';
        if ($return) return $code;
        else echo $code;
    } else {
        return var_export($var, $return);
    }
}

?>

http://www.php.net/manual/en/function.var-export.php#54440

You might want to check out this tutorial: http://www.webdesignerwall.com/tutorials/css-decorative-gallery/

In it the writer uses an empty span element to add an overlaying image. You can use jQuery to inject said span elements, if you'd like to keep your code as clean as possible. An example is also given in the aforementioned article.

Hope this helps!

-Dave

the warning or error of kind IMPLICIT DECLARATION is that the compiler is expecting a Function Declaration/Prototype..

It might either be a header file or your own function Declaration..

Try using the following pattern in scanf. It will read until the end of the line:

scanf("%d\n", &n)

You won't need the getchar() inside the loop since scanf will read the whole line. The floats won't match the scanf pattern and the prompt will ask for an integer again.

I tried with one column of string values with nan.

To remove the nan and fill the empty string:

df.columnname.replace(np.nan,'',regex = True)

To remove the nan and fill some values:

df.columnname.replace(np.nan,'value',regex = True)

I tried df.iloc also. but it needs the index of the column. so you need to look into the table again. simply the above method reduced one step.

You need to iterate your list and call String#trim for searching:

String search = "A";
for(String str: myList) {
    if(str.trim().contains(search))
       return true;
}
return false;

OR if you want to perform ignore case search, then use:

search = search.toLowerCase(); // outside loop

// inside the loop
if(str.trim().toLowerCase().contains(search))

You should really use Angular UI for that needs. Check it out: Angular UI Dialog

In a nutshell, with Angular UI dialog, you can pass variable from a controller to the dialog controller using resolve. Here's your "from" controller:

var d = $dialog.dialog({
  backdrop: true,
  keyboard: true,
  backdropClick: true,
  templateUrl:  '<url_of_your_template>',
  controller: 'MyDialogCtrl',
  // Interesting stuff here.
  resolve: {
    username: 'foo'
  }
});

d.open();

And in your dialog controller:

angular.module('mymodule')
  .controller('MyDialogCtrl', function ($scope, username) {
  // Here, username is 'foo'
  $scope.username = username;
}

EDIT: Since the new version of the ui-dialog, the resolve entry becomes:

resolve: { username: function () { return 'foo'; } }

You'd have to define alphanumerics exactly, but

/^(\w{3,5})$/ 

Should match any digit/character/_ combination of length 3-5.

If you also need the dash, make sure to escape it (\-) add it, like this: :

/^([\w\-]{3,5})$/ 

Also: the ^ anchor means that the sequence has to start at the beginning of the line (character string), and the $ that it ends at the end of the line (character string). So your value string mustn't contain anything else, or it won't match.

I have written ffcnt to speed up recursive file counting under specific circumstances: rotational disks and filesystems that support extent mapping.

It can be an order of magnitude faster than ls or find based approaches, but YMMV.

Try this

myApp.config(['$httpProvider', function($httpProvider) {
        $httpProvider.defaults.useXDomain = true;
        delete $httpProvider.defaults.headers.common['X-Requested-With'];
    }
]);

Just setting useXDomain = true is not enough. AJAX request are also send with the X-Requested-With header, which indicate them as being AJAX. Removing the header is necessary, so the server is not rejecting the incoming request.

You can also use this syntax (L[start:stop:step]):

mylist = [1,2,3,4,5,6,7,8,9,10]
for i in mylist[::2]:
    print i,
# prints 1 3 5 7 9

for i in mylist[1::2]:
    print i,
# prints 2 4 6 8 10

Where the first digit is the starting index (defaults to beginning of list or 0), 2nd is ending slice index (defaults to end of list), and the third digit is the offset or step.

I have found the problem: Don't use CDN (this is causing the problem!), instead save the jquery file locally on your server and then the problem is away.

Didn't wan to mess with carbon. So here's my solution

$start = new \DateTime('now');
$start->modify('first day of this month');
$end = new \DateTime('now');
$end->modify('last day of this month');

$new_releases = Game::whereBetween('release', array($start, $end))->get();

For your first method change ws.Range("A") to ws.Range("A:A") which will search the entirety of column a, like so:

Sub Find_Bingo()

        Dim wb As Workbook
        Dim ws As Worksheet
        Dim FoundCell As Range
        Set wb = ActiveWorkbook
        Set ws = ActiveSheet

            Const WHAT_TO_FIND As String = "Bingo"

            Set FoundCell = ws.Range("A:A").Find(What:=WHAT_TO_FIND)
            If Not FoundCell Is Nothing Then
                MsgBox (WHAT_TO_FIND & " found in row: " & FoundCell.Row)
            Else
                MsgBox (WHAT_TO_FIND & " not found")
            End If
End Sub

For your second method, you are using Bingo as a variable instead of a string literal. This is a good example of why I add Option Explicit to the top of all of my code modules, as when you try to run the code it will direct you to this "variable" which is undefined and not intended to be a variable at all.

Additionally, when you are using With...End With you need a period . before you reference Cells, so Cells should be .Cells. This mimics the normal qualifying behavior (i.e. Sheet1.Cells.Find..)

Change Bingo to "Bingo" and change Cells to .Cells

With Sheet1
        Set FoundCell = .Cells.Find(What:="Bingo", After:=.Cells(1, 1), _
        LookIn:=xlValues, lookat:=xlPart, SearchOrder:=xlByRows, _
        SearchDirection:=xlNext, MatchCase:=False, SearchFormat:=False)
    End With

If Not FoundCell Is Nothing Then
        MsgBox ("""Bingo"" found in row " & FoundCell.Row)
Else
        MsgBox ("Bingo not found")
End If

Update

In my

With Sheet1
    .....
End With

The Sheet1 refers to a worksheet's code name, not the name of the worksheet itself. For example, say I open a new blank Excel workbook. The default worksheet is just Sheet1. I can refer to that in code either with the code name of Sheet1 or I can refer to it with the index of Sheets("Sheet1"). The advantage to using a codename is that it does not change if you change the name of the worksheet.

Continuing this example, let's say I renamed Sheet1 to Data. Using Sheet1 would continue to work, as the code name doesn't change, but now using Sheets("Sheet1") would return an error and that syntax must be updated to the new name of the sheet, so it would need to be Sheets("Data").

In the VB Editor you would see something like this:

Notice how, even though I changed the name to Data, there is still a Sheet1 to the left. That is what I mean by codename.

The Data worksheet can be referenced in two ways:

Debug.Print Sheet1.Name
Debug.Print Sheets("Data").Name

Both should return Data

More discussion on worksheet code names can be found here.

This does not address the original question, but I thought I would expand on the answer zinturs gave. If you would like to determine the appropriately-signed distance between any two numbers, you could use a custom function like this:

import math

def distance(a, b):
    if (a == b):
        return 0
    elif (a < 0) and (b < 0) or (a > 0) and (b > 0):
        if (a < b):
            return (abs(abs(a) - abs(b)))
        else:
            return -(abs(abs(a) - abs(b)))
    else:
        return math.copysign((abs(a) + abs(b)),b)

print(distance(3,-5))  # -8

print(distance(-3,5))  #  8

print(distance(-3,-5)) #  2

print(distance(5,3))   # -2

print(distance(5,5))   #  0

print(distance(-5,3))  #  8

print(distance(5,-3))  # -8

Please share simpler or more pythonic approaches, if you have one.

There's always System.Web.Security.Membership.GeneratePassword(int length, int numberOfNonAlphanumericCharacters).

I created the following utility to set the console size and scroll buffers.

I compiled it using DEV C++ (http://www.bloodshed.net/devcpp.html).

An executable is included in https://sourceforge.net/projects/wa2l-wintools/.

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

using namespace std;


// SetWindow(Width,Height,WidthBuffer,HeightBuffer) -- set console size and buffer dimensions
//
void SetWindow(int Width, int Height, int WidthBuffer, int HeightBuffer) { 
    _COORD coord; 
    coord.X = WidthBuffer; 
    coord.Y = HeightBuffer; 

    _SMALL_RECT Rect; 
    Rect.Top = 0; 
    Rect.Left = 0; 
    Rect.Bottom = Height - 1; 
    Rect.Right = Width - 1; 

    HANDLE Handle = GetStdHandle(STD_OUTPUT_HANDLE);      // Get Handle 
    SetConsoleScreenBufferSize(Handle, coord);            // Set Buffer Size 
    SetConsoleWindowInfo(Handle, TRUE, &Rect);            // Set Window Size 
}  // SetWindow



// main(Width,Height,WidthBuffer,HeightBuffer) -- main
//
int main(int argc, char *argv[]) {     
    int width = 80;
    int height = 25;
    int wbuffer = width + 200;
    int hbuffer = height + 1000;

    if ( argc == 5 ){
        width = atoi(argv[1]);
        height = atoi(argv[2]);
        wbuffer = atoi(argv[3]);
        hbuffer = atoi(argv[4]);
    } else if ( argc > 1 ) {
        cout << "Usage: " << argv[0] << " [ width height bufferwidth bufferheight ]" << endl << endl;
        cout << "  Where" << endl;
        cout << "    width            console width" << endl;
        cout << "    height           console height" << endl;
        cout << "    bufferwidth      scroll buffer width" << endl;
        cout << "    bufferheight     scroll buffer height" << endl;
        return 4;
    }    

    SetWindow(width,height,wbuffer,hbuffer);
    return 0;
} 

Here's a somewhat cleaner way of implementing this. This makes the following changes:

1. The code is DRYed up a bit to remove redundant and repeated code and strings.
2. The code is made more generic/reusable.
3. We make the cache into an object so it has a self-contained interface and there are fewer globals.
4. We compare .src attributes instead of DOM elements to make it work properly.

Code:

function imageCache(base, firstNum, lastNum) {
    this.cache = [];
    var img;
    for (var i = firstNum; i <= lastnum; i++) {
        img = new Image();
        img.src = base + i + ".jpg";
        this.cache.push(img);
    }
}

imageCache.prototype.nextImage(id) {
    var element = document.getElementById(id);
    var targetSrc = element.src;
    var cache = this.cache;
    for (var i = 0; i < cache.length; i++) {
        if (cache[i].src) === targetSrc) {
            i++;
            if (i >= cache.length) {
                i = 0;
            }
            element.src = cache[i].src;
            return;
        }
    }
}

// sample usage

var myCache = new imageCache('images/img/Splash_image', 1, 6);
myCache.nextImage("foo");

Some advantages of this more object oriented and DRYed approach:

1. You can add more images by just creating the images in the numeric sequences and changing one numeric value in the constructor rather than copying lots more lines of array declarations.
2. You can use this more than one place in your app by just creating more than one imageCache object.
3. You can change the base URL by changing one string rather than N strings.
4. The code size is smaller (because of the removal of repeated code).
5. The cache object could easily be extended to offer more capabilities such as first, last, skip, etc...
6. You could add centralize error handling in one place so if one image doesn't exist and doesn't load successfully, it's automatically removed from the cache.
7. You can reuse this in other web pages you develop by only change the arguments to the constructor and not actually changing the implementation code.

P.S. If you don't know what DRY stands for, it's "Don't Repeat Yourself" and basically means that you should never have many copies of similar looking code. Anytime you have that, it should be reduced somehow to a loop or function or something that removes the need for lots of similarly looking copies of code. The end result will be smaller, usually easier to maintain and often more reusable.

Here it is:

def convert_bytes(size):
   for x in ['bytes', 'KB', 'MB', 'GB', 'TB']:
       if size < 1024.0:
           return "%3.1f %s" % (size, x)
       size /= 1024.0

   return size

Addition to third answer: If you're using non-english Windows, you can find "Credentials Manager" through "Control panel" > "User Accounts" > "Credentials Manager" Icon of Credentials Manager

&& lets you do something based on whether the previous command completed successfully - that's why you tend to see it chained as do_something && do_something_else_that_depended_on_something.

The issue is that the * is getting interpreted by your shell and is expanding to a file named TEST_FILE that happens to be in your current working directory, so you're telling find to execute the command named TEST_FILE which doesn't exist. I'm not sure what you're trying to accomplish with that *, you should just remove it.

Furthermore, you should use the idiom -exec program '{}' \+ instead of -exec program '{}' \; so that find doesn't fork a new process for each file. With ;, a new process is forked for each file, whereas with +, it only forks one process and passes all of the files on a single command line, which for simple programs like chmod is much more efficient.

Lastly, chmod can do recursive changes on its own with the -R flag, so unless you need to search for specific files, just do this:

chmod -R 777 /Users/Test/Desktop/PATH

I was having the same problem. Don't know if you've solved this or not, but what I was really trying to do was access a network share with AD credentials. WNetAddConnection2() is what you need to use in that case.

A String (System.String) is a type defined inside the .NET framework. The String class is not mutable. This means that every time you do an action to an System.String instance, the .NET compiler create a new instance of the string. This operation is hidden to the developer.

A System.Text.StringBuilder is class that represents a mutable string. This class provides some useful methods that make the user able to manage the String wrapped by the StringBuilder. Notice that all the manipulations are made on the same StringBuilder instance.

Microsoft encourages the use of StringBuilder because it is more effective in terms of memory usage.

Add a min attribute

<input type="number" min="0">

I got a similar error when the actual cause was that my disk was full. After deleting some files, git pull began to work as I expected.

A trap is a software interrupt.If you write a program in which you declare a variable having divide by zero value then it is treated as a trap.Whenever you run this program it will throw same error at the same time.System call is a special version of trap in which a program asks os for its required service. In case of interrupt(a general word for hardware interrupts)like an i/o error,the cpu is interrupted at random time and off course it is not the fault of our programmers.It is the hardware that brings them up.

A little more involved example with recursion.

function recompose(obj,string){
    var parts = string.split('.');
    var newObj = obj[parts[0]];
    if(parts[1]){
        parts.splice(0,1);
        var newString = parts.join('.');
        return recompose(newObj,newString);
    }
    return newObj;
}


var obj = { a: { b: '1', c: '2', d:{a:{b:'blah'}}}};

alert(recompose(obj,'a.d.a.b')); //blah

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]}

You have to specify that test1 is global:

test1 = 0
def testFunc():
    global test1
    test1 += 1
testFunc()

I increased the virtual memory of sdcard up to 512 MB for the emulator and that was enough

int is nothing but an interruption i.e the processor will put its current execution to hold.

0x80 is nothing but a system call or the kernel call. i.e the system function will be executed.

To be specific 0x80 represents rt_sigtimedwait/init_module/restart_sys it varies from architecture to architecture.

After reading the other answers (First by @duncan-finney and then by @Marrs) I set out to find the change log that explains the idiomatic react-router 2.x way of solving this. The documentation on using location (which you need for queries) in components is actually contradicted by the actual code. So if you follow their advice, you get big angry warnings like this:

Warning: [react-router] `context.location` is deprecated, please use a route component's `props.location` instead.

It turns out that you cannot have a context property called location that uses the location type. But you can use a context property called loc that uses the location type. So the solution is a small modification on their source as follows:

const RouteComponent = React.createClass({
    childContextTypes: {
        loc: PropTypes.location
    },

    getChildContext() {
        return { location: this.props.location }
    }
});

const ChildComponent = React.createClass({
    contextTypes: {
        loc: PropTypes.location
    },
    render() {
        console.log(this.context.loc);
        return(<div>this.context.loc.query</div>);
    }
});

You could also pass down only the parts of the location object you want in your children get the same benefit. It didn't change the warning to change to the object type. Hope that helps.

Download MongoDB and install it on your local machine. Link https://www.mongodb.com/try/download/enterprise

Extract the file and put it on the desktop. Create another folder where you want to store the data. I have created mongodb-data folder. Then run the below command.

Desktop/mongodb/bin/mongod --dbpath=/Users/yourname/Desktop/mongodb-data/

Before the hyphen is the executable path of your mongoDB and after hyphen is your data store.

You can do this using groupby to group on the column of interest and then apply list to every group:

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

Out[1]: 
   a  b
0  A  1
1  A  2
2  B  5
3  B  5
4  B  4
5  C  6

In [2]: df.groupby('a')['b'].apply(list)
Out[2]: 
a
A       [1, 2]
B    [5, 5, 4]
C          [6]
Name: b, dtype: object

In [3]: df1 = df.groupby('a')['b'].apply(list).reset_index(name='new')
        df1
Out[3]: 
   a        new
0  A     [1, 2]
1  B  [5, 5, 4]
2  C        [6]

Ejecting is not the best option as well as editing something under node_modules. react-app-rewired is not maintained and has the warning:

...you now "own" the configs. No support will be provided. Proceed with caution...

Solution - use craco.

It is advisable to use PyPi regex module if you plan to match specific Unicode property classes. This library has also proven to be more stable, especially handling large texts, and yields consistent results across various Python versions. All you need to do is to keep it up-to-date.

If you install it (using pip intall regex or pip3 install regex), you may use

import regex
print ( regex.sub(r'\P{L}+', '', 'ABCLac1-2!???3§4“5def”') )
// => ABCLac???def

to remove all chunks of 1 or more characters other than Unicode letters from text. See an online Python demo. You may also use "".join(regex.findall(r'\p{L}+', 'ABCLac1-2!???3§4“5def”')) to get the same result.

In Python re, in order to match any Unicode letter, one may use the [^\W\d_] construct (Match any unicode letter?).

So, to remove all non-letter characters, you may either match all letters and join the results:

result = "".join(re.findall(r'[^\W\d_]', text))

Or, remove all chars other than those matched with [^\W\d_]:

result = re.sub(r'([^\W\d_])|.', r'\1', text, re.DOTALL)

See the regex demo online. However, you may get inconsistent results across various Python versions because the Unicode standard is evolving, and the set of chars matched with \w will depend on the Python version. Using PyPi regex library is highly recommended to get consistent results.

Try doing it from the command like:

cat dump.sql | sqlite3 database.db

This will obviously only work with SQL statements in dump.sql. I'm not sure how to import a CSV.

You could try using the third-party tool called NirCmd. It is a genuine, free command line utility. If or when you have it, use this code in a batch file:

title Open Word
nircmd win hide title "Open Word"
start "C:\Program" "Files" "(x86)\Microsoft" "Office\Office12\WINWORD.exe
nircmd wait 20
nircmd win min foreground
exit

This program, in order, changes its title, hides itself according to its title, starts Word, waits 20 milliseconds as a buffer for Word to settle, minimizes Word by assuming it is now the top window, and then exits itself. This program should work as intended as long as their are no key presses or clicks in that ~50 millisecond time window, which shouldn't be hard.

As for installing nircmd on your computer, use this link, and click "Download NirCmd" at the bottom of the page. Save the .zip folder to a normal directory (like "My Documents"), extract it, and copy "nircmd.exe" to %systemroot%\system32, and there you go. Now you have nircmd included with your command line utilities.

You can try it. hope it will be useful.

SELECT * FROM `table` WHERE `Value` COLLATE latin1_general_cs = "IAreSavage"

Angular RC5 & RC6

If you are getting the above mentioned error in your Jasmine tests, it is most likely because you have to declare the unrenderable component in your TestBed.configureTestingModule({}).

The TestBed configures and initializes an environment for unit testing and provides methods for mocking/creating/injecting components and services in unit tests.

If you don't declare the component before your unit tests are executed, Angular will not know what <courses></courses> is in your template file.

Here is an example:

import {async, ComponentFixture, TestBed} from "@angular/core/testing";
import {AppComponent} from "../app.component";
import {CoursesComponent} from './courses.component';

describe('CoursesComponent', () => {
  let component: CoursesComponent;
  let fixture: ComponentFixture<CoursesComponent>;

  beforeEach(async(() => {
    TestBed.configureTestingModule({
      declarations: [
        AppComponent,
        CoursesComponent
      ],
      imports: [
        BrowserModule
        // If you have any other imports add them here
      ]
    })
    .compileComponents();
  }));

  beforeEach(() => {
    fixture = TestBed.createComponent(CoursesComponent);
    component = fixture.componentInstance;
    fixture.detectChanges();
  });

  it('should create', () => {
    expect(component).toBeTruthy();
  });
});

Just came across this message but in c# code. Not sure if it's relevant (exactly the same error message though).

I was debugging the code with breakpoints and expanded some collections through private members while debugger was at a breakpoint. Having re-run the code without digging through structures made the error message go away. It seems like the act of looking into private lazy-loaded collections has made NHibernate load things that were not supposed to be loaded at that time (because they were in private members).

The code itself is wrapped in a fairly complicated transaction that can update large number of records and many dependencies as part of that transaction (import process).

Hopefully a clue to anyone else who comes across the issue.

Have got the same error as in header because of failed attempt to compile my project with java 8 and then reattempting to compile with java 6. Some classes where compiled at the first attempt with 8 and did not recompile with 6. Mixed classes did not compile then. Cleaning project solved the problem. This answer is not strictly relevant to the question, but could be useful for someone.

You can use any parent methods. For this you should to send this methods from you parent to you child like any simple value. And you can use many methods from the parent at one time. For example:

var Parent = React.createClass({
    someMethod: function(value) {
        console.log("value from child", value)
    },
    someMethod2: function(value) {
        console.log("second method used", value)
    },
    render: function() {
      return (<Child someMethod={this.someMethod} someMethod2={this.someMethod2} />);
    }
});

And use it into the Child like this (for any actions or into any child methods):

var Child = React.createClass({
    getInitialState: function() {
      return {
        value: 'bar'
      }
    },
    render: function() {
      return (<input type="text" value={this.state.value} onClick={this.props.someMethod} onChange={this.props.someMethod2} />);
    }
});

Unfortunately, at the time of writing this answer, there is no direct way to do this. You need to:

1. use a semi-transparent image for background (much easier).
2. add an extra element (like div) next to children which you want the opaque, add background to it and after making it semi-transparent, position it behind mentioned children.

Just for fun, here's a sample with a recursive function which (I hope) should be a bit simpler to understand and to use with your code:

Function Recurse(sPath As String) As String

    Dim FSO As New FileSystemObject
    Dim myFolder As Folder
    Dim mySubFolder As Folder

    Set myFolder = FSO.GetFolder(sPath)
    For Each mySubFolder In myFolder.SubFolders
        Call TestSub(mySubFolder.Path)
        Recurse = Recurse(mySubFolder.Path)
    Next

End Function

Sub TestR()

    Call Recurse("D:\Projets\")

End Sub

Sub TestSub(ByVal s As String)

    Debug.Print s

End Sub

Edit: Here's how you can implement this code in your workbook to achieve your objective.

Sub TestSub(ByVal s As String)

    Dim FSO As New FileSystemObject
    Dim myFolder As Folder
    Dim myFile As File

    Set myFolder = FSO.GetFolder(s)
    For Each myFile In myFolder.Files
        If myFile.Name = Range("E1").Value Then
            Debug.Print myFile.Name 'Or do whatever you want with the file
        End If
    Next

End Sub

Here, I just debug the name of the found file, the rest is up to you. ;)

Of course, some would say it's a bit clumsy to call twice the FileSystemObject so you could simply write your code like this (depends on wether you want to compartmentalize or not):

Function Recurse(sPath As String) As String

    Dim FSO As New FileSystemObject
    Dim myFolder As Folder
    Dim mySubFolder As Folder
    Dim myFile As File

    Set myFolder = FSO.GetFolder(sPath)

    For Each mySubFolder In myFolder.SubFolders
        For Each myFile In mySubFolder.Files
            If myFile.Name = Range("E1").Value Then
                Debug.Print myFile.Name & " in " & myFile.Path 'Or do whatever you want with the file
                Exit For
            End If
        Next
        Recurse = Recurse(mySubFolder.Path)
    Next

End Function

Sub TestR()

    Call Recurse("D:\Projets\")

End Sub

s = "BINGO"
print(s.replace("", " ")[1: -1])

ssize_t is not included in the standard and isn't portable. size_t should be used when handling the size of objects (there's ptrdiff_t too, for pointer differences).

System is a final class from the java.lang package.

out is a class variable of type PrintStream declared in the System class.

println is a method of the PrintStream class.

So, I've found a solution for what I'm looking for, which is:

print open('f2').read().decode('string-escape').decode("utf-8")

There are some unusual codecs that are useful here. This particular reading allows one to take UTF-8 representations from within Python, copy them into an ASCII file, and have them be read in to Unicode. Under the "string-escape" decode, the slashes won't be doubled.

This allows for the sort of round trip that I was imagining.

I suggest to approximate locally the Earth surface as a sphere with radius given by the WGS84 ellipsoid at the given latitude. I suspect that the exact computation of latMin and latMax would require elliptic functions and would not yield an appreciable increase in accuracy (WGS84 is itself an approximation).

My implementation follows (It's written in Python; I have not tested it):

# degrees to radians
def deg2rad(degrees):
    return math.pi*degrees/180.0
# radians to degrees
def rad2deg(radians):
    return 180.0*radians/math.pi

# Semi-axes of WGS-84 geoidal reference
WGS84_a = 6378137.0  # Major semiaxis [m]
WGS84_b = 6356752.3  # Minor semiaxis [m]

# Earth radius at a given latitude, according to the WGS-84 ellipsoid [m]
def WGS84EarthRadius(lat):
    # http://en.wikipedia.org/wiki/Earth_radius
    An = WGS84_a*WGS84_a * math.cos(lat)
    Bn = WGS84_b*WGS84_b * math.sin(lat)
    Ad = WGS84_a * math.cos(lat)
    Bd = WGS84_b * math.sin(lat)
    return math.sqrt( (An*An + Bn*Bn)/(Ad*Ad + Bd*Bd) )

# Bounding box surrounding the point at given coordinates,
# assuming local approximation of Earth surface as a sphere
# of radius given by WGS84
def boundingBox(latitudeInDegrees, longitudeInDegrees, halfSideInKm):
    lat = deg2rad(latitudeInDegrees)
    lon = deg2rad(longitudeInDegrees)
    halfSide = 1000*halfSideInKm

    # Radius of Earth at given latitude
    radius = WGS84EarthRadius(lat)
    # Radius of the parallel at given latitude
    pradius = radius*math.cos(lat)

    latMin = lat - halfSide/radius
    latMax = lat + halfSide/radius
    lonMin = lon - halfSide/pradius
    lonMax = lon + halfSide/pradius

    return (rad2deg(latMin), rad2deg(lonMin), rad2deg(latMax), rad2deg(lonMax))

EDIT: The following code converts (degrees, primes, seconds) to degrees + fractions of a degree, and vice versa (not tested):

def dps2deg(degrees, primes, seconds):
    return degrees + primes/60.0 + seconds/3600.0

def deg2dps(degrees):
    intdeg = math.floor(degrees)
    primes = (degrees - intdeg)*60.0
    intpri = math.floor(primes)
    seconds = (primes - intpri)*60.0
    intsec = round(seconds)
    return (int(intdeg), int(intpri), int(intsec))

For me it got resolved using following link: http://viralpatel.net/blogs/wamp-server-not-getting-started-problem/

Try this:

package main

import (
  "io"; 
  )


func main() {
  contents,_ := io.ReadFile("filename");
  println(string(contents));
  io.WriteFile("filename", contents, 0644);
}

Since you have only one parameter, you could try decorating it with the [FromBody] attribute, or change the method to accept a DTO with value as a property, as I suggested here: MVC4 RC WebApi parameter binding

UPDATE: The official ASP.NET site was updated today with an excellent explanation: https://docs.microsoft.com/en-us/aspnet/web-api/overview/advanced/sending-html-form-data-part-1

In a nutshell, when sending a single simple type in the body, send just the value prefixed with an equal sign (=), e.g. body:

=test

You can call a stored procedure using the following syntax:

$result = mysql_query('CALL getNodeChildren(2)');

You can try with this code

var result =  (from  item in List
              select new 
              {
                 EmpLoc = item.empLoc,
                 EmpPL= item.empPL,
                 EmpShift= item.empShift
              })
              .ToList()
              .Distinct();

You can open any of the following files:

/etc/profile
~/.bash_profile
~/.bash_login   (if .bash_profile does not exist)
~/.profile      (if .bash_login does not exist)

And add:

export PATH="$PATH:your/new/path/here"

No need to use any tool for that

1. Set Tab Spaces to 1.
2. Select whole block of code and then press Shift + Tab

Shift + Tab = Shift text right to left

Data Access Object Pattern or DAO pattern is used to separate low level data accessing API or operations from high level business services. Following are the participants in Data Access Object Pattern.

Data Access Object Interface - This interface defines the standard operations to be performed on a model object(s).

Data Access Object concrete class -This class implements above interface. This class is responsible to get data from a datasource which can be database / xml or any other storage mechanism.

Model Object or Value Object - This object is simple POJO containing get/set methods to store data retrieved using DAO class.

Sample code here..

Limit is very simple, example limit first 50 rows

val df_subset = data.limit(50)

Here is a list of special characters that you can escape when creating a string literal for JSON:

\b  Backspace (ASCII code 08)
\f  Form feed (ASCII code 0C)
\n  New line
\r  Carriage return
\t  Tab
\v  Vertical tab
\'  Apostrophe or single quote
\"  Double quote
\\  Backslash character

Reference: String literals

Some of these are more optional than others. For instance, your string should be perfectly valid whether you escape the tab character or leave in a tab literal. You should certainly be handling the backslash and quote characters, though.

Build up a JavaScript data structure with the required information, then turn it into the json string at the end.

Based on what I think you're doing, try something like this:

var result = [];
for (var name in goals) {
  if (goals.hasOwnProperty(name)) {
    result.push({name: name, goals: goals[name]});
  }
}

res.contentType('application/json');
res.send(JSON.stringify(result));

or something along those lines.

Check the uploaded image size using Javascript

        var imgsize=img/1024; 
        alert(imgsize);
      }

Let me add an example here:

I'm trying to build Alluxio on windows platform and got the same issue, it's because the pom.xml contains below step:

The .sh file is not executable on windows so the error throws.

Comment it out if you do want build Alluxio on windows.

Yes, the above answers are correct and works fine on Unix based systems like Linux & MAC OS X.

Write above code inside following tags < Directory "c:\projects" > < / Directory > c:(you can add any directory d: e:) is drive where you have created your project folder.

Alias /projects "c:\projects"

Now you can access the pr0jects directory on your browser :

localhost/projects/

I had the same problem with Visual Studio 2008 and solved adding the following event handler to the textbox:

        private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
    {
        if ((e.KeyChar >= 'a') && (e.KeyChar <= 'z'))
        {
            int iPos = textBox1.SelectionStart;
            int iLen = textBox1.SelectionLength;
            textBox1.Text = textBox1.Text.Remove(iPos, iLen).Insert(iPos, Char.ToUpper(e.KeyChar).ToString());
            textBox1.SelectionStart = iPos + 1;
            e.Handled = true;
        }
    }

It works even if you type a lowercase character in a textbox where some characters are selected. I don't know if the code works with a Multiline textbox.

You are reinventing the wheel. Normal PowerShell scripts have parameters starting with -, like script.ps1 -server http://devserver

Then you handle them in param section in the beginning of the file.

You can also assign default values to your params, read them from console if not available or stop script execution:

 param (
    [string]$server = "http://defaultserver",
    [Parameter(Mandatory=$true)][string]$username,
    [string]$password = $( Read-Host "Input password, please" )
 )

Inside the script you can simply

write-output $server

since all parameters become variables available in script scope.

In this example, the $server gets a default value if the script is called without it, script stops if you omit the -username parameter and asks for terminal input if -password is omitted.

Update: You might also want to pass a "flag" (a boolean true/false parameter) to a PowerShell script. For instance, your script may accept a "force" where the script runs in a more careful mode when force is not used.

The keyword for that is [switch] parameter type:

 param (
    [string]$server = "http://defaultserver",
    [string]$password = $( Read-Host "Input password, please" ),
    [switch]$force = $false
 )

Inside the script then you would work with it like this:

if ($force) {
  //deletes a file or does something "bad"
}

Now, when calling the script you'd set the switch/flag parameter like this:

.\yourscript.ps1 -server "http://otherserver" -force

If you explicitly want to state that the flag is not set, there is a special syntax for that

.\yourscript.ps1 -server "http://otherserver" -force:$false

Links to relevant Microsoft documentation (for PowerShell 5.0; tho versions 3.0 and 4.0 are also available at the links):

• about_Scripts
• about_Functions
• about_Functions_Advanced_Parameters

If the array is unsorted, you will need to use linear search.

This solved my use case that is: "Compile webpack stuff in nodejs container on Windows running Docker Desktop with WSL2 and have the built assets under your currently logged in user."

docker run -u 1000 -v "$PWD":/build -w /build node:10.23 /bin/sh -c 'npm install && npm run build'

Based on the answer by eigenfield. Thank you!

Also this material helped me understand what is going on.

Some awk version.

awk '/19:55/{c=5} c-->0'
awk '/19:55/{c=5} c && c--'

When pattern found, set c=5
If c is true, print and decrease number of c

If all you want to do is store some static values in a lookup table, you can use an Object Literal (the same format used by JSON) to do it compactly:

var table = { one: [1,10,5], two: [2], three: [3, 30, 300] }

And then access them using JavaScript's associative array syntax:

alert(table['one']);    // Will alert with [1,10,5]
alert(table['one'][1]); // Will alert with 10

Pre C# 6.0 solution

You can use this to get a name of any provided member:

public static class MemberInfoGetting
{
    public static string GetMemberName<T>(Expression<Func<T>> memberExpression)
    {
        MemberExpression expressionBody = (MemberExpression)memberExpression.Body;
        return expressionBody.Member.Name;
    }
}

To get name of a variable:

string testVariable = "value";
string nameOfTestVariable = MemberInfoGetting.GetMemberName(() => testVariable);

To get name of a parameter:

public class TestClass
{
    public void TestMethod(string param1, string param2)
    {
        string nameOfParam1 = MemberInfoGetting.GetMemberName(() => param1);
    }
}

C# 6.0 and higher solution

You can use the nameof operator for parameters, variables and properties alike:

string testVariable = "value";
string nameOfTestVariable = nameof(testVariable);

All answers here are correct when it comes to the ::selection pseudo element, and how it works. However, the question does in fact specifically ask how to use it on text inputs.

The only way to do that is to apply the rule via a parent of the input (any parent for that matter):

.parent ::-webkit-selection, [contenteditable]::-webkit-selection {_x000D_
 background: #ffb7b7;_x000D_
}_x000D_
_x000D_
.parent ::-moz-selection, [contenteditable]::-moz-selection {_x000D_
 background: #ffb7b7;_x000D_
}_x000D_
_x000D_
.parent ::selection, [contenteditable]::selection {_x000D_
 background: #ffb7b7;_x000D_
}_x000D_
_x000D_
/* Aesthetics */_x000D_
input, [contenteditable] {_x000D_
  border:1px solid black;_x000D_
  display:inline-block;_x000D_
  width: 150px;_x000D_
  height: 20px;_x000D_
  line-height: 20px;_x000D_
  padding: 3px;_x000D_
}

<span class="parent"><input type="text" value="Input" /></span>_x000D_
<span contenteditable>Content Editable</span>

@crobar, you are right that there is a dearth of multi-file examples, so I decided to share the following in the hopes that it helps others:

::::::::::::::
main.cpp
::::::::::::::

#include <iostream>

#include "UseSomething.h"
#include "Something.h"

int main()
{
    UseSomething y;
    std::cout << y.getValue() << '\n';
}

::::::::::::::
Something.h
::::::::::::::

#ifndef SOMETHING_H_
#define SOMETHING_H_

class Something
{
private:
    static int s_value;
public:
    static int getValue() { return s_value; } // static member function
};
#endif

::::::::::::::
Something.cpp
::::::::::::::

#include "Something.h"

int Something::s_value = 1; // initializer

::::::::::::::
UseSomething.h
::::::::::::::

#ifndef USESOMETHING_H_
#define USESOMETHING_H_

class UseSomething
{
public:
    int getValue();
};

#endif

::::::::::::::

#include "UseSomething.h"

int UseSomething::getValue()
{
    return(Something::getValue());
}

I found a solution for this problem after a long analysing procedure. After properly testing my php installation with the command line features I found out that the php is working well and could work with the mysql database. Btw. you can run code-files with php code with the command php -f filename.php
So I realized, it must something be wrong with the Apache.
I made a file with just the phpinfo() function inside.
Here I saw, that in the line
Loaded Configuration File
my config file was not loaded, instead there was mentioned (none).

Finally I found within the Apache configuration the entry

<IfModule php5_module>
    PHPINIDir "C:/xampp/php"
</IfModule>

But I've installed the PHP 7 and so the Apache could not load the php.ini file because there was no entry for that. I added

<IfModule php7_module>
    PHPINIDir "C:/xampp/php"
</IfModule>

and after restart Apache all works well.

These code blocks above I found in my httpd-xampp.conf file. May it is somewhere else at your configuration.
In the same file I had changed before the settings for the php 7 as replacement for the php 5 version.

#
# PHP-Module setup
#
#LoadFile "C:/xampp/php/php5ts.dll"
#LoadModule php5_module "C:/xampp/php/php5apache2_4.dll"
LoadFile "C:/xampp/php/php7ts.dll"
LoadModule php7_module "C:/xampp/php/php7apache2_4.dll"

As you can see I have the xampp package installed but this problem was just on the Apache side.

I don't know if it is possible in XAML-only but try the following:

Give your ComboBox a name so you can access it in the codebehind: "typesComboBox1"

Now try the following

typesComboBox1.ItemsSource = Enum.GetValues(typeof(ExampleEnum));

if your table is like this

rowId     col1    col2    col3    col4
 1          a       e       12       2
 2          b       f       42       5
 3          a       e       32       2
 4          b       f       44       5


var grouped = myTable.AsEnumerable().GroupBy(r=> new {pp1 =  r.Field<int>("col1"), pp2 = r.Field<int>("col2")});

Nathan Lee's answer is perfect. I just wanted to add something about position:absolute;. If you wanted to use position:absolute; like you had in your code, you have to think of it as pushing it away from one side of the page.

For example, if you wanted your div to be somewhere in the bottom, you would have to use position:absolute; top:500px;. That would push your div 500px from the top of the page. Same rule applies for all other directions.

DEMO

I just wish to add one important detail to the answers above. And it is that even if you import the projects from your chosen root directory they may not appear in bold so you won't be able to select them. The reason for this may be that the metadata of the projects is corrupted. If you do encounter this problem then the easiest and quickest way to fix it is to rid yourself of the workspace-folder and create a new one and copy+paste your projects (do it before you erase the old workspace) folders to this new workspace. Then, in your new worskapce, import the projects as the previous posts have explained.

erm it does work? I've just tested it?

/****** Object:  Table [dbo].[DateTest]    Script Date: 09/26/2008 10:44:21 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[DateTest](
    [Date1] [datetime] NULL,
    [Date2] [datetime] NOT NULL
) ON [PRIMARY]

GO
Insert into DateTest (Date1,Date2) VALUES (NULL,'1-Jan-2008')
Insert into DateTest (Date1,Date2) VALUES ('1-Jan-2008','1-Jan-2008')
Go
SELECT * FROM DateTest WHERE Date1 is not NULL
GO
SELECT * FROM DateTest WHERE Date2 is not NULL

An example based on Chuck's answer:

myIntToStr :: Int -> String
myIntToStr x
    | x < 3     = show x ++ " is less than three"
    | otherwise = "normal"

Note that without the show the third line will not compile.

The table is only dropped and re-created in cases where that's the only way SQL Server's Management Studio has been programmed to know how to do it.

There are certainly cases where it will do that when it doesn't need to, but there will also be cases where edits you make in Management Studio will not drop and re-create because it doesn't have to.

The problem is that enumerating all of the cases and determining which side of the line they fall on will be quite tedious.

This is why I like to use ALTER TABLE in a query window, instead of visual designers that hide what they're doing (and quite frankly have bugs) - I know exactly what is going to happen, and I can prepare for cases where the only possibility is to drop and re-create the table (which is some number less than how often SSMS will do that to you).

Since Java 1.5 you can use the String.format method. For example, to do the same thing as your example:

String format = String.format("%0%d", digits);
String result = String.format(format, num);
return result;

In this case, you're creating the format string using the width specified in digits, then applying it directly to the number. The format for this example is converted as follows:

%% --> %
0  --> 0
%d --> <value of digits>
d  --> d

So if digits is equal to 5, the format string becomes %05d which specifies an integer with a width of 5 printing leading zeroes. See the java docs for String.format for more information on the conversion specifiers.

While this question was asked I didn't know about it, but now if you use phpMyAdmin you can simply open the database and select the table(s) you want to truncate.

• At the bottom there is a drop down with many options. Open it and select Empty option under the heading Delete data or table.
• It takes you to the next page automatically where there is an option in checkbox called Enable foreign key checks. Just unselect it and press the Yes button and the selected table(s) will be truncated.

Maybe it internally runs the query suggested in user447951's answer, but it is very convenient to use from phpMyAdmin interface.

You can use this to replace the function if it doesn't exist:

<script>
if (!Array.prototype.indexOf) {
    Array.prototype.indexOf = function(elt /*, from*/) {
        var len = this.length >>> 0;

        var from = Number(arguments[1]) || 0;
        from = (from < 0) ? Math.ceil(from) : Math.floor(from);
        if (from < 0)
            from += len;

        for (; from < len; from++) {
            if (from in this && this[from] === elt)
                return from;
        }
        return -1;
    };
}
</script>

To load other file(css ,js) and folder(images) , in codeigniter project

we have to follow two simple step:

1.create folder public (can give any name) in your codeigniters folder put your bootstrap files css and js folder in side public folder. https://i.stack.imgur.com/O2gr6.jpg

2.now we have to use two line of code 1.load->helper('url'); ?> 2.

go to your view file

put first line to load base URL

   <?php $this->load->helper('url'); ?>

secondly in your html head tag put this

   <link rel="stylesheet" type="text/css" href="<?php echo base_url(); ?>/public/css/bootstrap.css">

now you can enjoy the bootstrap in your codeigniter

The basic difference between the two is that-

android:gravity is used for child elements of the view.

android:layout_gravity is used for this element with respect to parent view.

@Html.TextArea("txtNotes", "", 4, 0, new { @class = "k-textbox", style = "width: 100%; height: 100%;" })

Following are the ways

1. From the code (the way you have mentioned) ->

   displayBox.Text += sent + "\r\n";
   

   or

   displayBox.Text += sent + Environment.NewLine;
   

2. From the UI
   a) WPF

   Set TextWrapping="Wrap" and AcceptsReturn="True"   
   

   Press Enter key to the textbox and new line will be created

   b) Winform text box

   Set TextBox.MultiLine and TextBox.AcceptsReturn to true
   

You cannot do so - the browser will not allow this because of security concerns.

When a file is selected by using the input type=file object, the value of the value property depends on the value of the "Include local directory path when uploading files to a server" security setting for the security zone used to display the Web page containing the input object.

The fully qualified filename of the selected file is returned only when this setting is enabled. When the setting is disabled, Internet Explorer 8 replaces the local drive and directory path with the string C:\fakepath\ in order to prevent inappropriate information disclosure.

And other

You missed ); this at the end of the change event function.

Also do not create function for change event instead just use it as below,

<script type="text/javascript">

    $(function()
    {
        $('#fileUpload').on('change',function ()
        {
            var filePath = $(this).val();
            console.log(filePath);
        });
    });

</script>

This answer is not exactly what you want, but it might be useful in some cases. If you know the element has some dimensions when displayed, you can also use this:

var hasDisplayNone = (element.offsetHeight === 0 && element.offsetWidth === 0);

EDIT: Why this might be better than direct check of CSS display property? Because you do not need to check all parent elements. If some parent element has display: none, its children are hidden too but still has element.style.display !== 'none'.

Why to annoy the user with three different Dialog Boxes to enter things, why not do all this in one go in a single Dialog and save time, instead of testing the patience of the USER ?

You can add everything in a single Dialog, by putting all the fields on your JPanel and then adding this JPanel to your JOptionPane. Below code can clarify a bit more :

import java.awt.*;
import java.util.*;
import javax.swing.*;

public class AverageExample
{
    private double[] marks;
    private JTextField[] marksField;
    private JLabel resultLabel;

    public AverageExample()
    {
        marks = new double[3];
        marksField = new JTextField[3];
        marksField[0] = new JTextField(10);
        marksField[1] = new JTextField(10);
        marksField[2] = new JTextField(10);
    }

    private void displayGUI()
    {
        int selection = JOptionPane.showConfirmDialog(
                null, getPanel(), "Input Form : "
                                , JOptionPane.OK_CANCEL_OPTION
                                , JOptionPane.PLAIN_MESSAGE);

        if (selection == JOptionPane.OK_OPTION) 
        {
            for ( int i = 0; i < 3; i++)
            {
                marks[i] = Double.valueOf(marksField[i].getText());             
            }
            Arrays.sort(marks);
            double average = (marks[1] + marks[2]) / 2.0;
            JOptionPane.showMessageDialog(null
                    , "Average is : " + Double.toString(average)
                    , "Average : "
                    , JOptionPane.PLAIN_MESSAGE);
        }
        else if (selection == JOptionPane.CANCEL_OPTION)
        {
            // Do something here.
        }
    }

    private JPanel getPanel()
    {
        JPanel basePanel = new JPanel();
        //basePanel.setLayout(new BorderLayout(5, 5));
        basePanel.setOpaque(true);
        basePanel.setBackground(Color.BLUE.darker());

        JPanel centerPanel = new JPanel();
        centerPanel.setLayout(new GridLayout(3, 2, 5, 5));
        centerPanel.setBorder(
            BorderFactory.createEmptyBorder(5, 5, 5, 5));
        centerPanel.setOpaque(true);
        centerPanel.setBackground(Color.WHITE);

        JLabel mLabel1 = new JLabel("Enter Marks 1 : ");
        JLabel mLabel2 = new JLabel("Enter Marks 2 : ");
        JLabel mLabel3 = new JLabel("Enter Marks 3 : ");

        centerPanel.add(mLabel1);
        centerPanel.add(marksField[0]);
        centerPanel.add(mLabel2);
        centerPanel.add(marksField[1]);
        centerPanel.add(mLabel3);
        centerPanel.add(marksField[2]);

        basePanel.add(centerPanel);

        return basePanel;
    }

    public static void main(String... args)
    {
        SwingUtilities.invokeLater(new Runnable()
        {
            @Override
            public void run()
            {
                new AverageExample().displayGUI();

        });

These are compact methods to encrypt / decrypt strings with PHP using AES256 CBC:

function encryptString($plaintext, $password, $encoding = null) {
    $iv = openssl_random_pseudo_bytes(16);
    $ciphertext = openssl_encrypt($plaintext, "AES-256-CBC", hash('sha256', $password, true), OPENSSL_RAW_DATA, $iv);
    $hmac = hash_hmac('sha256', $ciphertext.$iv, hash('sha256', $password, true), true);
    return $encoding == "hex" ? bin2hex($iv.$hmac.$ciphertext) : ($encoding == "base64" ? base64_encode($iv.$hmac.$ciphertext) : $iv.$hmac.$ciphertext);
}

function decryptString($ciphertext, $password, $encoding = null) {
    $ciphertext = $encoding == "hex" ? hex2bin($ciphertext) : ($encoding == "base64" ? base64_decode($ciphertext) : $ciphertext);
    if (!hash_equals(hash_hmac('sha256', substr($ciphertext, 48).substr($ciphertext, 0, 16), hash('sha256', $password, true), true), substr($ciphertext, 16, 32))) return null;
    return openssl_decrypt(substr($ciphertext, 48), "AES-256-CBC", hash('sha256', $password, true), OPENSSL_RAW_DATA, substr($ciphertext, 0, 16));
}

Usage:

$enc = encryptString("mysecretText", "myPassword");
$dec = decryptString($enc, "myPassword");

I'm not sure what structure you want your resulting array in, but the following code will do what I think you're asking for:

int sum = 0;
int[] results = new int[100];
for (int i = 0; i < 100; i++) {
  sum += (i+1);
  results[i] = sum;
}

Gives you an array of the sum at each point in the loop [1, 3, 6, 10...]

Although they vary slightly as to how they retrieve a height value, i.e some would calculate the whole element including padding, margin, scrollbar, etc and others would just calculate the element in its raw form.
You can try these ones:

javascript:

var myDiv = document.getElementById("myDiv");
myDiv.clientHeight;
myDiv.scrollHeight;
myDiv.offsetHeight;

or in jquery:

$("#myDiv").height();
$("#myDiv").innerHeight();
$("#myDiv").outerHeight();

RFC 3066 gives the details of the allowed values (emphasis and links added):

All 2-letter subtags are interpreted as ISO 3166 alpha-2 country codes from [ISO 3166], or subsequently assigned by the ISO 3166 maintenance agency or governing standardization bodies, denoting the area to which this language variant relates.

I interpret that as meaning any valid (according to ISO 3166) 2-letter code is valid as a subtag. The RFC goes on to state:

Tags with second subtags of 3 to 8 letters may be registered with IANA, according to the rules in chapter 5 of this document.

By the way, that looks like a typo, since chapter 3 seems to relate to the the registration process, not chapter 5.

A quick search for the IANA registry reveals a very long list, of all the available language subtags. Here's one example from the list (which would be used as en-scouse):

Type: variant

Subtag: scouse

Description: Scouse

Added: 2006-09-18

Prefix: en

Comments: English Liverpudlian dialect known as 'Scouse'

There are all sorts of subtags available; a quick scroll has already revealed fr-1694acad (17th century French).

The usefulness of some of these (I would say the vast majority of these) tags, when it comes to documents designed for display in the browser, is limited. The W3C Internationalization specification simply states:

Browsers and other applications can use information about the language of content to deliver to users the most appropriate information, or to present information to users in the most appropriate way. The more content is tagged and tagged correctly, the more useful and pervasive such applications will become.

I'm struggling to find detailed information on how browsers behave when encountering different language tags, but they are most likely going to offer some benefit to those users who use a screen reader, which can use the tag to determine the language/dialect/accent in which to present the content.

It's also cleaner to use @JoinTable when an Entity could be the child in several parent/child relationships with different types of parents. To follow up with Behrang's example, imagine a Task can be the child of Project, Person, Department, Study, and Process.

Should the task table have 5 nullable foreign key fields? I think not...

The ubuntu package name is qt5-default, not qt.

1) Also you can use lateinit If you sure do your initialization later on onCreate() or elsewhere.

Use this

lateinit var left: Node

Instead of this

var left: Node? = null

2) And there is other way that use !! end of variable when you use it like this

queue.add(left!!) // add !!

For Current date and time as the name for a file on the file system. Now call the string.Format method, and combine it with DateTime.Now, for a method that outputs the correct string based on the date and time.

using System;
using System.IO;

class Program
{
    static void Main()
    {
        //
        // Write file containing the date with BIN extension
        //
        string n = string.Format("text-{0:yyyy-MM-dd_hh-mm-ss-tt}.bin",
            DateTime.Now);
        File.WriteAllText(n, "abc");
    }
}

Output :

C:\Users\Fez\Documents\text-2020-01-08_05-23-13-PM.bin

"text-{0:yyyy-MM-dd_hh-mm-ss-tt}.bin"

text- The first part of the output required Files will all start with text-

{0: Indicates that this is a string placeholder The zero indicates the index of the parameters inserted here

yyyy- Prints the year in four digits followed by a dash This has a "year 10000" problem

MM- Prints the month in two digits

dd_ Prints the day in two digits followed by an underscore

hh- Prints the hour in two digits

mm- Prints the minute, also in two digits

ss- As expected, it prints the seconds

tt Prints AM or PM depending on the time of day

str.erase(str.begin() + str.size() - 1)

str.erase(str.rbegin()) does not compile unfortunately, since reverse_iterator cannot be converted to a normal_iterator.

C++11 is your friend in this case.

Directory.GetCurrentDirectory

string dirpath = Directory.GetCurrentDirectory();

Prepend this dirpath to the filename to get the complete path.

As @Dan Puzey indicated in the comments, it would be better to use Path.Combine

Path.Combine(Directory.GetCurrentDirectory(), filename)

I had the same issue and this piece of code worked out for me.

names(data)[names(data) == "oldVariableName"] <- "newVariableName"

In short, this code does the following:

names(data) looks into all the names in the dataframe (data)

[names(data) == oldVariableName] extracts the variable name (oldVariableName) you want to get renamed and <- "newVariableName" assigns the new variable name.

the above answer from @DannyBeckett helped me a lot,

I put the following in a batch file & I place it in the same folder where ResourceHacker.exe & the EXE I work on is located & it works excellent. [you may edit it to fit your needs]

    @echo off
    :start1
    set /p newVersion=Enter version number [?.?.?.?]:
    if "%newVersion%" == "" goto start1
    :start2
    set /p file=Enter EXE name [for 'program.exe' enter 'program']:
    if "%file%" == "" goto start2
    for /f "tokens=1-4 delims=." %%a in ('echo %newVersion%') do (set ResVersion=%%a,%%b,%%c,%%d)
    (
    echo:VS_VERSION_INFO VERSIONINFO
    echo:    FILEVERSION    %ResVersion%
    echo:    PRODUCTVERSION %ResVersion%
    echo:{
    echo:    BLOCK "StringFileInfo"
    echo:    {
    echo:        BLOCK "040904b0"
    echo:        {
    echo:            VALUE "CompanyName",        "MyCompany\0"
    echo:            VALUE "FileDescription",    "TestFile\0"
    echo:            VALUE "FileVersion",        "%newVersion%\0"
    echo:            VALUE "LegalCopyright",     "COPYRIGHT © 2019 MyCompany\0"
    echo:            VALUE "OriginalFilename",   "%file%.exe\0"
    echo:            VALUE "ProductName",        "Test\0"
    echo:            VALUE "ProductVersion",     "%newVersion%\0"
    echo:        }
    echo:    }
    echo:    BLOCK "VarFileInfo"
    echo:    {
    echo:        VALUE "Translation", 0x409, 1200
    echo:    }
    echo:}
    ) >Resources.rc     &&      echo setting Resources.rc
    ResourceHacker.exe -open resources.rc -save resources.res -action compile -log CONSOLE
    ResourceHacker -open "%file%.exe" -save "%file%Res.exe" -action addoverwrite -resource "resources.res"  -log CONSOLE
    ResourceHacker.exe -open "%file%Res.exe" -save "%file%Ico.exe" -action addskip -res "%file%.ico" -mask ICONGROUP,MAINICON, -log CONSOLE
    xCopy /y /f "%file%Ico.exe" "%file%.exe"
    echo.
    echo.
    echo your compiled file %file%.exe is ready
    pause

[as a side note i used resource hacker also to compile the res file, not GoRC]

The reason is the browser can not understand it and try to somehow translate it to what it can understand and in this case into a hexadecimal value!...

chucknorris starts with c which is recognised character in hexadecimal, also it's converting all unrecognised characters into 0!

So chucknorris in hexadecimal format becomes: c00c00000000, all other characters become 0 and c remains where they are...

Now they get divided by 3 for RGB(red, green, blue)... R: c00c, G: 0000, B:0000...

But we know valid hexadecimal for RGB is just 2 characters, means R: c0, G: 00, B:00

So the real result is:

bgcolor="#c00000";

I also added the steps in the image as a quick reference for you:

git fetch && git checkout branch_name( "branch_name" here is the name of the branch )

Then you will see message, Switched to a new branch 'branch_name' Branch 'branch_name' set up to track remote branch 'branch_name' from 'origin'.

For me this worked.

$ sudo apt-get install openjfx

The docker cli credential scheme is unsurprisingly uncomplicated, just take a look:

cat ~/.docker/config.json

{
  "auths": {
    "dockerregistry.myregistry.com": {},
    "https://index.docker.io/v1/": {}

This exists on Windows (use Get-Content ~\.docker\config.json) and you can also poke around the credential tool which also lists the username ... and I think you can even retrieve the password

. "C:\Program Files\Docker\Docker\resources\bin\docker-credential-wincred.exe" list

{"https://index.docker.io/v1/":"kcd"}

You can create you own exception by inheriting from java.lang.Exception Here is an example that can help you do that.

In my case, I needed to find the directory name of a full path (of a directory) so I simply did:

var dirName = path.Split('\\').Last();

@niutech I was having the similar issue which is caused by Rocket Loader Module by Cloudflare. Just disable it for the website and it will sort out all your related issues.

Here is a solution I use in one of my project.

network_utils.telnet

import socket
from timeit import default_timer as timer

def telnet(hostname, port=23, timeout=1):
    start = timer()
    connection = socket.socket()
    connection.settimeout(timeout)
    try:
        connection.connect((hostname, port))
        end = timer()
        delta = end - start
    except (socket.timeout, socket.gaierror) as error:
        logger.debug('telnet error: ', error)
        delta = None
    finally:
        connection.close()

    return {
        hostname: delta
    }

Tests

def test_telnet_is_null_when_host_unreachable(self):
    hostname = 'unreachable'

    response = network_utils.telnet(hostname)

    self.assertDictEqual(response, {'unreachable': None})

def test_telnet_give_time_when_reachable(self):
    hostname = '127.0.0.1'

    response = network_utils.telnet(hostname, port=22)

    self.assertGreater(response[hostname], 0)

function fibo(count) {

    //when count is 0, just return 
    if (!count) return;

    //Push 0 as the first element into an array
    var fibArr = [0];

    //when count is 1, just print and return
    if (count === 1) {
        console.log(fibArr);
        return;
    }

    //Now push 1 as the next element to the same array
    fibArr.push(1);

    //Start the iteration from 2 to the count
    for(var i = 2, len = count; i < len; i++) {
        //Addition of previous and one before previous
        fibArr.push(fibArr[i-1] + fibArr[i-2]);
    }

    //outputs the final fibonacci series
    console.log(fibArr);
}

Whatever count we need, we can give it to above fibo method and get the fibonacci series upto the count.

fibo(20); //output: [0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181]

I experienced the same problem while trying to write a code concerning Speech_to_Text.

The solution was very simple. Uninstall the previous pywin32 using the pip method

pip uninstall pywin32

The above will remove the existing one which is by default for 32 bit computers. And install it again using

pip install pywin32

This will install the one for the 64 bit computer which you are using.

using latest jquery mutation

var $target = jQuery(".required-entry");
            var observer = new MutationObserver(function(mutations) {
                mutations.forEach(function(mutation) {
                    if (mutation.attributeName === "class") {
                        var attributeValue = jQuery(mutation.target).prop(mutation.attributeName);
                        if (attributeValue.indexOf("search-class") >= 0){
                            // do what you want
                        }
                    }
                });
            });
            observer.observe($target[0],  {
                attributes: true
            });

// any code which update div having class required-entry which is in $target like $target.addClass('search-class');

Per JamieL's answer to another post:

Since Express.js 3x the response object has a json() method which sets all the headers correctly for you.

Example:

res.json({"foo": "bar"});

The commands are adduser and addgroup.

Here's a template for Docker you can use in busybox environments (alpine) as well as Debian-based environments (Ubuntu, etc.):

ENV USER=docker
ENV UID=12345
ENV GID=23456

RUN adduser \
    --disabled-password \
    --gecos "" \
    --home "$(pwd)" \
    --ingroup "$USER" \
    --no-create-home \
    --uid "$UID" \
    "$USER"

Note the following:

• --disabled-password prevents prompt for a password
• --gecos "" circumvents the prompt for "Full Name" etc. on Debian-based systems
• --home "$(pwd)" sets the user's home to the WORKDIR. You may not want this.
• --no-create-home prevents cruft getting copied into the directory from /etc/skel

The usage description for these applications is missing the long flags present in the code for adduser and addgroup.

The following long-form flags should work both in alpine as well as debian-derivatives:

adduser

BusyBox v1.28.4 (2018-05-30 10:45:57 UTC) multi-call binary.

Usage: adduser [OPTIONS] USER [GROUP]

Create new user, or add USER to GROUP

        --home DIR           Home directory
        --gecos GECOS        GECOS field
        --shell SHELL        Login shell
        --ingroup GRP        Group (by name)
        --system             Create a system user
        --disabled-password  Don't assign a password
        --no-create-home     Don't create home directory
        --uid UID            User id

One thing to note is that if --ingroup isn't set then the GID is assigned to match the UID. If the GID corresponding to the provided UID already exists adduser will fail.

addgroup

BusyBox v1.28.4 (2018-05-30 10:45:57 UTC) multi-call binary.

Usage: addgroup [-g GID] [-S] [USER] GROUP

Add a group or add a user to a group

        --gid GID  Group id
        --system   Create a system group

I discovered all of this while trying to write my own alternative to the fixuid project for running containers as the hosts UID/GID.

My entrypoint helper script can be found on GitHub.

The intent is to prepend that script as the first argument to ENTRYPOINT which should cause Docker to infer UID and GID from a relevant bind mount.

An environment variable "TEMPLATE" may be required to determine where the permissions should be inferred from.

(At the time of writing I don't have documentation for my script. It's still on the todo list!!)

Like this:

>>>mystr = "abcdefghijkl"
>>>mystr[-4:]
'ijkl'

This slices the string's last 4 characters. The -4 starts the range from the string's end. A modified expression with [:-4] removes the same 4 characters from the end of the string:

>>>mystr[:-4]
'abcdefgh'

For more information on slicing see this Stack Overflow answer.

the_string = raw_input()
name, age = the_string.split()

From a broken link:

Within an Aggregate there is an Aggregate Root. The Aggregate Root is the parent Entity to all other Entities and Value Objects within the Aggregate.

A Repository operates upon an Aggregate Root.

More info can also be found here.

if (mysql_query("INSERT INTO PEOPLE (NAME ) VALUES ('COLE')")or die(mysql_error())) {
  echo 'Success';
} else {
  echo 'Fail';
} 

Although since you have or die(mysql_error()) it will show the mysql_error() on the screen when it fails. You should probably remove that if it isnt the desired result
