String[] split = data.split("\\|",-1);

This is not the actual requirement in all the time. The Drawback of above is show below:

Scenerio 1:
When all data are present:
    String data = "5|6|7||8|9|10|";
    String[] split = data.split("\\|");
    String[] splt = data.split("\\|",-1);
    System.out.println(split.length); //output: 7
    System.out.println(splt.length); //output: 8

When data is missing:

Scenerio 2: Data Missing
    String data = "5|6|7||8|||";
    String[] split = data.split("\\|");
    String[] splt = data.split("\\|",-1);
    System.out.println(split.length); //output: 5
    System.out.println(splt.length); //output: 8

Real requirement is length should be 7 although there is data missing. Because there are cases such as when I need to insert in database or something else. We can achieve this by using below approach.

    String data = "5|6|7||8|||";
    String[] split = data.split("\\|");
    String[] splt = data.replaceAll("\\|$","").split("\\|",-1);
    System.out.println(split.length); //output: 5
    System.out.println(splt.length); //output:7

What I've done here is, I'm removing "|" pipe at the end and then splitting the String. If you have "," as a seperator then you need to add ",$" inside replaceAll.

In my case, the issue was that Oracle was installing it to a different location than I was used to.

Download from Oracle: http://java.com/en/download/mac_download.jsp?locale=en

1. Verify that it's installed properly by looking in System Prefs:

   • Command-Space to open Spotlight, type 'System Preferences', hit enter.
   • Click Java icon in bottom row. After the Java Control Panel opens, click 'Java' tab, 'View...', and verify that your install worked. You can see a 'Path' there also, which you can sub into the commands below in case they are different than mine.

2. Verify that the version is as you expect (sub in your path as needed):

   /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java -version

3. Create link from /usr/bin/java to your new install

   sudo ln -fs /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java /usr/bin/java

4. Sanity check your version:

   java -version

Do which sshpass in your command line to get the absolute path to sshpass and replace it in the bash script.

You should also probably do the same with the command you are trying to run.

The problem might be that it is not finding it.

You should use fgetcsv. Since you cannot import a file as a stream because the csv is a variable, then you should spoof the string as a file by using php://temp or php://memory first:

$fp = fopen("php://temp", 'r+');
fputs($fp, $csvText);
rewind($fp);

Then you will have no problem using fgetcsv:

$csv = [];
while ( ($data = fgetcsv($fp) ) !== FALSE ) {
    $csv[] = $data;
}

$data will be an array of a single csv line (which may include line breaks or commas, etc), as it should be.

Caveat: The memory limit of php://temp can be controlled by appending /maxmemory:NN, where NN is the maximum amount of data to keep in memory before using a temporary file, in bytes. (the default is 2 MB) http://www.php.net/manual/en/wrappers.php.php

First make sure that Dog class implements the method public String toString() then use

System.out.println(list.get(index))

where index is the position inside the list. Of course since you provide your implementation you can decide how dog prints itself.

The C standard defines the [] operator as follows:

a[b] == *(a + b)

Therefore a[5] will evaluate to:

*(a + 5)

and 5[a] will evaluate to:

*(5 + a)

a is a pointer to the first element of the array. a[5] is the value that's 5 elements further from a, which is the same as *(a + 5), and from elementary school math we know those are equal (addition is commutative).

Basically VOLUME and -v option are almost equal. These mean 'mount specific directory on your container'. For example, VOLUME /data and -v /data is exactly same meaning. If you run the image that have VOLUME /data or with -v /data option, /data directory is mounted your container. This directory doesn't belong to your container.

Imagine that You add some files to /data on the container, then commit the container into new image. There isn't any files on data directory because mounted /data directory is belong to original container.

$ docker run -it -v /data --name volume ubuntu:14.04 bash
root@2b5e0f2d37cd:/# cd /data
root@2b5e0f2d37cd:/data# touch 1 2 3 4 5 6 7 8 9
root@2b5e0f2d37cd:/data# cd /tmp
root@2b5e0f2d37cd:/tmp# touch 1 2 3 4 5 6 7 8 9
root@2b5e0f2d37cd:/tmp# exit
exit

$ docker commit volume nacyot/volume  
835cfe3d8d159622507ba3256bb1c0b0d6e7c1419ae32751ad0f925c40378945
nacyot $ docker run -it nacyot/volume
root@dbe335c7e64d:/# cd /data

root@dbe335c7e64d:/tmp# ls
1  2  3  4  5  6  7  8  9
root@dbe335c7e64d:/tmp# 
root@dbe335c7e64d:/tmp# 

This mounted directory like /data is used to store data that is not belong to your application. And you can predefine the data directory that is not belong to the container by using VOLUME.

A difference between Volume and -v option is that you can use -v option dynamically on starting container. It mean you can mount some directory dynamically. And another difference is that you can mount your host directory on your container by using -v

Use timedelta.total_seconds().

This solution allows you to forget select element. Helpful when you do not have an id on select elements.

$("#first").select2()
.on("select2:select", function (e) {
    var selected_element = $(e.currentTarget);
    var select_val = selected_element.val();
});

You are inside a namespace so you should use \Exception to specify the global namespace:

try {

  $this->buildXMLHeader();

} catch (\Exception $e) {

    return $e->getMessage();
}

In your code you've used catch (Exception $e) so Exception is being searched in/as:

App\Services\PayUService\Exception

Since there is no Exception class inside App\Services\PayUService so it's not being triggered. Alternatively, you can use a use statement at the top of your class like use Exception; and then you can use catch (Exception $e).

You can also add new json objects into your json, using the extend function,

var newJson = $.extend({}, {my:"json"}, {other:"json"});
// result -> {my: "json", other: "json"}

A very good option for the extend function is the recursive merge. Just add the true value as the first parameter (read the documentation for more options). Example,

var newJson = $.extend(true, {}, {
    my:"json",
    nestedJson: {a1:1, a2:2}
}, {
    other:"json",
    nestedJson: {b1:1, b2:2}
});
// result -> {my: "json", other: "json", nestedJson: {a1:1, a2:2, b1:1, b2:2}}

I wrote a package (https://github.com/alexsanjoseph/compareDF) since I had the same issue.

  > df1 <- data.frame(a = 1:5, b=letters[1:5], row = 1:5)
  > df2 <- data.frame(a = 1:3, b=letters[1:3], row = 1:3)
  > df_compare = compare_df(df1, df2, "row")

  > df_compare$comparison_df
    row chng_type a b
  1   4         + 4 d
  2   5         + 5 e

A more complicated example:

library(compareDF)
df1 = data.frame(id1 = c("Mazda RX4", "Mazda RX4 Wag", "Datsun 710",
                         "Hornet 4 Drive", "Duster 360", "Merc 240D"),
                 id2 = c("Maz", "Maz", "Dat", "Hor", "Dus", "Mer"),
                 hp = c(110, 110, 181, 110, 245, 62),
                 cyl = c(6, 6, 4, 6, 8, 4),
                 qsec = c(16.46, 17.02, 33.00, 19.44, 15.84, 20.00))

df2 = data.frame(id1 = c("Mazda RX4", "Mazda RX4 Wag", "Datsun 710",
                         "Hornet 4 Drive", " Hornet Sportabout", "Valiant"),
                 id2 = c("Maz", "Maz", "Dat", "Hor", "Dus", "Val"),
                 hp = c(110, 110, 93, 110, 175, 105),
                 cyl = c(6, 6, 4, 6, 8, 6),
                 qsec = c(16.46, 17.02, 18.61, 19.44, 17.02, 20.22))

> df_compare$comparison_df
    grp chng_type                id1 id2  hp cyl  qsec

The package also has an html_output command for quick checking

df_compare$html_output

This works:

var event = jQuery.Event('keypress');
event.which = 13; 
event.keyCode = 13; //keycode to trigger this for simulating enter
jQuery(this).trigger(event);

    public void setScrollViewListener(ScrollViewListener scrollViewListener) {

        if (scrollViewListener != null) {
            scrollViewListener.onScrollChanged(this, l, t, oldl, oldt);
        }
    }

I needed something different because I wanted to use a generic approach. I'm reading the enum to and from byte arrays. This is where I come up with:

public interface EnumConverter {
    public Number convert();
}



public class ByteArrayConverter {
@SuppressWarnings("unchecked")
public static Enum<?> convertToEnum(byte[] values, Class<?> fieldType, NumberSystem numberSystem) throws InvalidDataException {
    if (values == null || values.length == 0) {
        final String message = "The values parameter must contain the value";
        throw new IllegalArgumentException(message);
    }

    if (!dtoFieldType.isEnum()) {
        final String message = "dtoFieldType must be an Enum.";
        throw new IllegalArgumentException(message);
    }

    if (!EnumConverter.class.isAssignableFrom(fieldType)) {
        final String message = "fieldType must implement the EnumConverter interface.";
        throw new IllegalArgumentException(message);
    }

    Enum<?> result = null;
    Integer enumValue = (Integer) convertToType(values, Integer.class, numberSystem); // Our enum's use Integer or Byte for the value field.

    for (Object enumConstant : fieldType.getEnumConstants()) {
        Number ev = ((EnumConverter) enumConstant).convert();

        if (enumValue.equals(ev)) {
            result = (Enum<?>) enumConstant;
            break;
        }
    }

    if (result == null) {
        throw new EnumConstantNotPresentException((Class<? extends Enum>) fieldType, enumValue.toString());
    }

    return result;
}

public static byte[] convertEnumToBytes(Enum<?> value, int requiredLength, NumberSystem numberSystem) throws InvalidDataException {
    if (!(value instanceof EnumConverter)) {
        final String message = "dtoFieldType must implement the EnumConverter interface.";
        throw new IllegalArgumentException(message);
    }

    Number enumValue = ((EnumConverter) value).convert();
    byte[] result = convertToBytes(enumValue, requiredLength, numberSystem);
    return result;
}

public static Object convertToType(byte[] values, Class<?> type, NumberSystem numberSystem) throws InvalidDataException {
    // some logic to convert the byte array supplied by the values param to an Object.
}

public static byte[] convertToBytes(Object value, int requiredLength, NumberSystem numberSystem) throws InvalidDataException {
    // some logic to convert the Object supplied by the'value' param to a byte array.
}
}

Example of enum's:

public enum EnumIntegerMock implements EnumConverter {
    VALUE0(0), VALUE1(1), VALUE2(2);

    private final int value;

    private EnumIntegerMock(int value) {
        this.value = value;
    }

public Integer convert() {
    return value;
}

}

public enum EnumByteMock implements EnumConverter {
    VALUE0(0), VALUE1(1), VALUE2(2);

    private final byte value;

    private EnumByteMock(int value) {
        this.value = (byte) value;
    }

    public Byte convert() {
        return value;
    }
}

It's really not an 'either/or' situation. AJAX stands for Asynchronous JavaScript and XML, and JQuery is a JavaScript library that takes the pain out of writing common JavaScript routines.

It's the difference between a thing (jQuery) and a process (AJAX). To compare them would be to compare apples and oranges.

The clean, fast, and easy solutions posted as of the date of this answer are unsatisfactory. They are constructed over the flawed statement that SVG documents lack z order. Libraries are not necessary either. One line of code can perform most operations to manipulate the z order of objects or groups of objects that might be required in the development of an app that moves 2D objects around in an x-y-z space.

Z Order Definitely Exists in SVG Document Fragments

What is called an SVG document fragment is a tree of elements derived from the base node type SVGElement. The root node of an SVG document fragment is an SVGSVGElement, which corresponds to an HTML5 <svg> tag. The SVGGElement corresponds to the <g> tag and permits aggregating children.

Having a z-index attribute on the SVGElement as in CSS would defeat the SVG rendering model. Sections 3.3 and 3.4 of W3C SVG Recommendation v1.1 2nd Edition state that SVG document fragments (trees of offspring from an SVGSVGElement) are rendered using what is called a depth first search of the tree. That scheme is a z order in every sense of the term.

Z order is actually a computer vision shortcut to avoid the need for true 3D rendering with the complexities and computing demands of ray tracing. The linear equation for the implicit z-index of elements in an SVG document fragment.

z-index = z-index_of_svg_tag + depth_first_tree_index / tree_node_qty

This is important because if you want to move a circle that was below a square to above it, you simply insert the square before the circle. This can be done easily in JavaScript.

Supporting Methods

SVGElement instances have two methods that support simple and easy z order manipulation.

• parent.removeChild(child)
• parent.insertBefore(child, childRef)

The Correct Answer That Doesn't Create a Mess

Because the SVGGElement (<g> tag) can be removed and inserted just as easily as a SVGCircleElement or any other shape, image layers typical of Adobe products and other graphics tools can be implemented with ease using the SVGGElement. This JavaScript is essentially a Move Below command.

parent.insertBefore(parent.removeChild(gRobot), gDoorway)

If the layer of a robot drawn as children of SVGGElement gRobot was before the doorway drawn as children of SVGGElement gDoorway, the robot is now behind the doorway because the z order of the doorway is now one plus the z order of the robot.

A Move Above command is almost as easy.

parent.insertBefore(parent.removeChild(gRobot), gDoorway.nextSibling())

Just think a=a and b=b to remember this.

insert after = move above
insert before = move below

Leaving the DOM in a State Consistent With the View

The reason this answer is correct is because it is minimal and complete and, like the internals of Adobe products or other well designed graphics editors, leaves the internal representation in a state that is consistent with the view created by rendering.

Alternative But Limited Approach

Another approach commonly used is to use CSS z-index in conjunction with multiple SVG document fragments (SVG tags) with mostly transparent backgrounds in all but the bottom one. Again, this defeats the elegance of the SVG rendering model, making it difficult to move objects up or down in the z order.

NOTES:

1. (https://www.w3.org/TR/SVG/render.html v 1.1, 2nd Edition, 16 August 2011)

   3.3 Rendering Order Elements in an SVG document fragment have an implicit drawing order, with the first elements in the SVG document fragment getting "painted" first. Subsequent elements are painted on top of previously painted elements.

   3.4 How groups are rendered Grouping elements such as the ‘g’ element (see container elements) have the effect of producing a temporary separate canvas initialized to transparent black onto which child elements are painted. Upon the completion of the group, any filter effects specified for the group are applied to create a modified temporary canvas. The modified temporary canvas is composited into the background, taking into account any group-level masking and opacity settings on the group.

Perhaps a little beyond all but the most precocious of six-year-olds, but a few examples that helped make the concept of closure in JavaScript click for me.

A closure is a function that has access to another function's scope (its variables and functions). The easiest way to create a closure is with a function within a function; the reason being that in JavaScript a function always has access to its containing function’s scope.

function outerFunction() {_x000D_
    var outerVar = "monkey";_x000D_
    _x000D_
    function innerFunction() {_x000D_
        alert(outerVar);_x000D_
    }_x000D_
    _x000D_
    innerFunction();_x000D_
}_x000D_
_x000D_
outerFunction();

ALERT: monkey

In the above example, outerFunction is called which in turn calls innerFunction. Note how outerVar is available to innerFunction, evidenced by its correctly alerting the value of outerVar.

Now consider the following:

function outerFunction() {_x000D_
    var outerVar = "monkey";_x000D_
    _x000D_
    function innerFunction() {_x000D_
        return outerVar;_x000D_
    }_x000D_
    _x000D_
    return innerFunction;_x000D_
}_x000D_
_x000D_
var referenceToInnerFunction = outerFunction();_x000D_
alert(referenceToInnerFunction());

ALERT: monkey

referenceToInnerFunction is set to outerFunction(), which simply returns a reference to innerFunction. When referenceToInnerFunction is called, it returns outerVar. Again, as above, this demonstrates that innerFunction has access to outerVar, a variable of outerFunction. Furthermore, it is interesting to note that it retains this access even after outerFunction has finished executing.

And here is where things get really interesting. If we were to get rid of outerFunction, say set it to null, you might think that referenceToInnerFunction would loose its access to the value of outerVar. But this is not the case.

function outerFunction() {_x000D_
    var outerVar = "monkey";_x000D_
    _x000D_
    function innerFunction() {_x000D_
        return outerVar;_x000D_
    }_x000D_
    _x000D_
    return innerFunction;_x000D_
}_x000D_
_x000D_
var referenceToInnerFunction = outerFunction();_x000D_
alert(referenceToInnerFunction());_x000D_
_x000D_
outerFunction = null;_x000D_
alert(referenceToInnerFunction());

ALERT: monkey ALERT: monkey

But how is this so? How can referenceToInnerFunction still know the value of outerVar now that outerFunction has been set to null?

The reason that referenceToInnerFunction can still access the value of outerVar is because when the closure was first created by placing innerFunction inside of outerFunction, innerFunction added a reference to outerFunction’s scope (its variables and functions) to its scope chain. What this means is that innerFunction has a pointer or reference to all of outerFunction’s variables, including outerVar. So even when outerFunction has finished executing, or even if it is deleted or set to null, the variables in its scope, like outerVar, stick around in memory because of the outstanding reference to them on the part of the innerFunction that has been returned to referenceToInnerFunction. To truly release outerVar and the rest of outerFunction’s variables from memory you would have to get rid of this outstanding reference to them, say by setting referenceToInnerFunction to null as well.

//////////

Two other things about closures to note. First, the closure will always have access to the last values of its containing function.

function outerFunction() {_x000D_
    var outerVar = "monkey";_x000D_
    _x000D_
    function innerFunction() {_x000D_
        alert(outerVar);_x000D_
    }_x000D_
    _x000D_
    outerVar = "gorilla";_x000D_
_x000D_
    innerFunction();_x000D_
}_x000D_
_x000D_
outerFunction();

ALERT: gorilla

Second, when a closure is created, it retains a reference to all of its enclosing function’s variables and functions; it doesn’t get to pick and choose. And but so, closures should be used sparingly, or at least carefully, as they can be memory intensive; a lot of variables can be kept in memory long after a containing function has finished executing.

There is a node.js library called named-regexp that you could use in your node.js projects (on in the browser by packaging the library with browserify or other packaging scripts). However, the library cannot be used with regular expressions that contain non-named capturing groups.

If you count the opening capturing braces in your regular expression you can create a mapping between named capturing groups and the numbered capturing groups in your regex and can mix and match freely. You just have to remove the group names before using the regex. I've written three functions that demonstrate that. See this gist: https://gist.github.com/gbirke/2cc2370135b665eee3ef

If you're using AVD manager add a hardware property Keyboard support and set it to false.

That should disable the shown keyboard, and show the virtual one.

I had this exact problem today and the problem was that the version I was trying to release:perform was already in the Nexus repo.

In my case this was likely due to a network disconnect during an earlier invocation of release:perform. Even though I lost my connection, it appears the release succeeded.

For anyone trying to do this in asp.net core. You can use claims.

public class CustomEmailProvider : IUserIdProvider
{
    public virtual string GetUserId(HubConnectionContext connection)
    {
        return connection.User?.FindFirst(ClaimTypes.Email)?.Value;
    }
}

Any identifier can be used, but it must be unique. If you use a name identifier for example, it means if there are multiple users with the same name as the recipient, the message would be delivered to them as well. I have chosen email because it is unique to every user.

Then register the service in the startup class.

services.AddSingleton<IUserIdProvider, CustomEmailProvider>();

Next. Add the claims during user registration.

var result = await _userManager.CreateAsync(user, Model.Password);
if (result.Succeeded)
{
    await _userManager.AddClaimAsync(user, new Claim(ClaimTypes.Email, Model.Email));
}

To send message to the specific user.

public class ChatHub : Hub
{
    public async Task SendMessage(string receiver, string message)
    {
        await Clients.User(receiver).SendAsync("ReceiveMessage", message);
    }
}

Note: The message sender won't be notified the message is sent. If you want a notification on the sender's end. Change the SendMessage method to this.

public async Task SendMessage(string sender, string receiver, string message)
{
    await Clients.Users(sender, receiver).SendAsync("ReceiveMessage", message);
}

These steps are only necessary if you need to change the default identifier. Otherwise, skip to the last step where you can simply send messages by passing userIds or connectionIds to SendMessage. For more

The easiest is setting a program variable (see GDB: assignment):

(gdb) l
6       {
7           int i;
8           struct file *f, *ftmp;
9
(gdb) set variable i = 10
(gdb) p i
$1 = 10

Or you can just update arbitrary (writable) location by address:

(gdb) set {int}0x83040 = 4

There's more. Read the manual.

Which version of JUnit is this? I've only ever seen delta, not epsilon - but that's a side issue!

From the JUnit javadoc:

delta - the maximum delta between expected and actual for which both numbers are still considered equal.

It's probably overkill, but I typically use a really small number, e.g.

private static final double DELTA = 1e-15;

@Test
public void testDelta(){
    assertEquals(123.456, 123.456, DELTA);
}

If you're using hamcrest assertions, you can just use the standard equalTo() with two doubles (it doesn't use a delta). However if you want a delta, you can just use closeTo() (see javadoc), e.g.

private static final double DELTA = 1e-15;

@Test
public void testDelta(){
    assertThat(123.456, equalTo(123.456));
    assertThat(123.456, closeTo(123.456, DELTA));
}

FYI the upcoming JUnit 5 will also make delta optional when calling assertEquals() with two doubles. The implementation (if you're interested) is:

private static boolean doublesAreEqual(double value1, double value2) {
    return Double.doubleToLongBits(value1) == Double.doubleToLongBits(value2);
}

for group headers/footers:

=iif(RunningValue(*group on field*,CountDistinct,"*parent group name*") Mod 2,"White","AliceBlue")

You can also use this to “reset” the row color count within each group. I wanted the first detail row in each sub group to start with White and this solution (when used on the detail row) allowed that to happen:

=IIF(RunningValue(Fields![Name].Value, CountDistinct, "NameOfPartnetGroup") Mod 2, "White", "Wheat")

See: http://msdn.microsoft.com/en-us/library/ms159136(v=sql.100).aspx

Your redirect URI in your code(keycloak.init) should be the same as the redirect URI set on Keycloak server (client -> Valid Uri)

First is you have to understand the difference between MyISAM and InnoDB Engines. And this is clearly stated on this link. You can use this sql statement if you want to convert InnoDB to MyISAM:

 ALTER TABLE t1 ENGINE=MyISAM;

Another solution: go through a filter with your inverted conditions : Example :

if(subscribtion.isOnce() && subscribtion.isCalled()){
                continue;
}

can be replaced with

.filter(s -> !(s.isOnce() && s.isCalled()))

The most straightforward approach seem to be using "return;" though.

I got this error when I modified an Nlog configuration file and didn't format the XML correctly.

Matt Turner's answer is definitely the right answer. However, in the spirit of Ken Williams' answer, you could also do:

capture.output(cat(sdata, sep="")) 

I experienced a similar issue in Visual Studio, which was being caused by an incorrect url() path to the font in question.

I stopped getting this error after changing (for instance):

@@font-face{
    font-family: "Example Font";
    src: url("/Fonts/ExampleFont.eot?#iefix");

to this:

@@font-face{
    font-family: "Example Font";
    src: url("../fonts/ExampleFont.eot?#iefix");

Use mysql_fetch_assoc instead of mysql_fetch_array

http://php.net/manual/en/function.mysql-fetch-assoc.php

Use .form-group.required without the space.

.form-group.required .control-label:after {
  content:"*";
  color:red;
}

Edit:

.form-group.required:not(.checkbox) .control-label:after, 
.form-group.required .text:after { /* change .text in whatever class of the text after the checkbox has */
   content:"*";
   color:red;
}

<div class="form-group required">
   <label class="col-md-2 control-label">&#160;</label>
   <div class="col-md-4">
      <div class="checkbox">
         <label class='text'> <!-- use this class -->
            <input class="" id="id_tos" name="tos" required="required" type="checkbox" /> I have read and agree to the Terms of Service
         </label>
      </div>
   </div>
</div>

Ok third edit:

CSS back to what is was

.form-group.required .control-label:after { 
   content:"*";
   color:red;
}

HTML:

<div class="form-group required">
   <label class="col-md-2">&#160;</label> <!-- remove class control-label -->
   <div class="col-md-4">
      <div class="checkbox">
         <label class='control-label'> <!-- use this class as the red * will be after control-label -->
            <input class="" id="id_tos" name="tos" required="required" type="checkbox" /> I have read and agree to the Terms of Service
         </label>
      </div>
   </div>
</div>

do a dir /s /b > out.txt and then add a guide at position 260

In powershell cmd /c dir /s /b |? {$_.length -gt 260}

Here's an alternative solution: if you have the date in PHP as a timestamp, bypass handling it with PHP and let the DB take care of transforming it by using the FROM_UNIXTIME function.

mysql> insert into a_table values(FROM_UNIXTIME(1231634282));
Query OK, 1 row affected (0.00 sec)

mysql> select * from a_table;

+---------------------+
| a_date              |
+---------------------+
| 2009-01-10 18:38:02 |
+---------------------+

First thing I should have noticed is that charAt is a method and assigning value to it using equal sign won't do anything. If a string is immutable, charAt method, to make change to the string object must receive an argument containing the new character. Unfortunately, string is immutable. To modify the string, I needed to use StringBuilder as suggested by Mr. Petar Ivanov.

Answer in link resolved my issue.

Before resolution, I tried by adding JAVA_HOME to windows environments. It resolved this error but created another issue. The solution in above link resolves this issue without creating additional issues.

For macOS many of the answers are already outdated according to official docs. Somehow the brew has changed and how we should install MongoDB, firstly uninstall it from your macOS (even though it might be not necessary) and then install it using these steps:

1. brew tap mongodb/brew
2. brew install [email protected]
3. brew services start [email protected]

Watch out for the 4.4 part, it'll change. If in the future it would break then refer to the official docs and install the version, which is suggested in the linked tutorial.

Unlike languages such as C, a Python variable is in scope for the whole of the function (or class, or module) where it appears, not just in the innermost "block". It is as though you declared int x at the top of the function (or class, or module), except that in Python you don't have to declare variables.

Note that the existence of the variable x is checked only at runtime -- that is, when you get to the print x statement. If __name__ didn't equal "__main__" then you would get an exception: NameError: name 'x' is not defined.

For Fedora:

# Fedora 18 or greater
sudo dnf group install "MinGW cross-compiler"

# Or (not recommended, because of its deprecation)
sudo yum groupinstall -y "MinGW cross-compiler"

for windows 10 use relativePanel instead of stack panel, and use

relativepanel.alignrightwithpanel="true"

for the contained elements.

Ravi's comment is essentially the answer. Functions take their own arguments. If you want them to be the same as the command-line arguments, you must pass them in. Otherwise, you're clearly calling a function without arguments.

That said, you could if you like store the command-line arguments in a global array to use within other functions:

my_function() {
    echo "stored arguments:"
    for arg in "${commandline_args[@]}"; do
        echo "    $arg"
    done
}

commandline_args=("$@")

my_function

You have to access the command-line arguments through the commandline_args variable, not $@, $1, $2, etc., but they're available. I'm unaware of any way to assign directly to the argument array, but if someone knows one, please enlighten me!

Also, note the way I've used and quoted $@ - this is how you ensure special characters (whitespace) don't get mucked up.

Just an update on more current OS's (Vista, Win7, etc.) - the temp file path has changed may be different based on several variables. The items below are not definitive, however, they are a few I have encountered:

"temp" environment variable setting - then it would be:

%temp%\Temporary ASP.NET Files

Permissions and what application/process (VS, IIS, IIS Express) is running the .Net compiler. Accessing the C:\WINDOWS\Microsoft.NET\Framework folders requires elevated permissions and if you are not developing under an account with sufficient permissions then this folder might be used:

c:\Users\[youruserid]\AppData\Local\Temp\Temporary ASP.NET Files

There are also cases where the temp folder can be set via config for a machine or site specific using this:

<compilation tempDirectory="d:\MyTempPlace" />

I even have a funky setup at work where we don't run Admin by default, plus the IT guys have login scripts that set %temp% and I get temp files in 3 different locations depending on what is compiling things! And I'm still not certain about how these paths get picked....sigh.

Still, dthrasher is correct, you can just delete these and VS and IIS will just recompile them as needed.

You can get a vertical space even though you have NO WHITESPACE whatsoever between your inline-block elements.

For me, this was caused by line-height. The simple fix was:

div.container {
    line-height: 0;
}
div.container > * {
    line-height: normal;
}

Coming from the Mozilla Documentation, "You can use the delete operator to delete variables declared implicitly but not those declared with the var statement. "

Here is the link: https://developer.mozilla.org/En/Core_JavaScript_1.5_Reference:Operators:Special_Operators:delete_Operator

For a start simply add the following to your application.properties file

spring.security.user.name=user
spring.security.user.password=pass

NB: with no double quote

Run your application and enter the credentials (user, pass)

I had the same problem, and a easy way i found to solve that was to make everything in the modal's body responsive(using boostrap classes) and my problem were solved.

You can use Tommy's method in forms as well:

@using (Html.BeginForm("Action", "Controller", FormMethod.Get, new { target = "_blank" }))
{
//code
}

Use below code:

// Variable to check
$email = "[email protected]";

// Remove all illegal characters from email
$email = filter_var($email, FILTER_SANITIZE_EMAIL);

// Validate e-mail
if (filter_var($email, FILTER_VALIDATE_EMAIL)) {
  echo("Email is a valid email address");
} else {
  echo("Oppps! Email is not a valid email address");
}

If you don't want to use str.lower(), you can use a regular expression:

import re

if re.search('mandy', 'Mandy Pande', re.IGNORECASE):
    # Is True

Regular expressions:

var numberPattern = /\d+/g;

'something102asdfkj1948948'.match( numberPattern )

This would return an Array with two elements inside, '102' and '1948948'. Operate as you wish. If it doesn't match any it will return null.

To concatenate them:

'something102asdfkj1948948'.match( numberPattern ).join('')

Assuming you're not dealing with complex decimals, this should suffice I suppose.

If you merged the branch, then reverted the merge using a pull request and merged that pull request to revert.

The easiest way I felt was to:

1. Take out a new branch from develop/master (where you merged)
2. Revert the "revert" using git revert -m 1 xxxxxx (if the revert was merged using a branch) or using git revert xxxxxx if it was a simple revert
3. The new branch should now have the changes you want to merge again.
4. Make changes or merge this branch to develop/master

If you are using iOS8, you should be using UIAlertController — UIAlertView is deprecated.

Here is an example of how to use it:

var refreshAlert = UIAlertController(title: "Refresh", message: "All data will be lost.", preferredStyle: UIAlertControllerStyle.Alert)

refreshAlert.addAction(UIAlertAction(title: "Ok", style: .Default, handler: { (action: UIAlertAction!) in
  print("Handle Ok logic here")
  }))

refreshAlert.addAction(UIAlertAction(title: "Cancel", style: .Cancel, handler: { (action: UIAlertAction!) in
  print("Handle Cancel Logic here")
  }))

presentViewController(refreshAlert, animated: true, completion: nil)

As you can see the block handlers for the UIAlertAction handle the button presses. A great tutorial is here (although this tutorial is not written using swift): http://hayageek.com/uialertcontroller-example-ios/

Swift 3 update:

let refreshAlert = UIAlertController(title: "Refresh", message: "All data will be lost.", preferredStyle: UIAlertControllerStyle.alert)

refreshAlert.addAction(UIAlertAction(title: "Ok", style: .default, handler: { (action: UIAlertAction!) in
    print("Handle Ok logic here")
}))

refreshAlert.addAction(UIAlertAction(title: "Cancel", style: .cancel, handler: { (action: UIAlertAction!) in
    print("Handle Cancel Logic here")
}))

present(refreshAlert, animated: true, completion: nil)

Swift 5 update:

let refreshAlert = UIAlertController(title: "Refresh", message: "All data will be lost.", preferredStyle: UIAlertControllerStyle.alert)

refreshAlert.addAction(UIAlertAction(title: "Ok", style: .default, handler: { (action: UIAlertAction!) in
      print("Handle Ok logic here")
}))

refreshAlert.addAction(UIAlertAction(title: "Cancel", style: .cancel, handler: { (action: UIAlertAction!) in
      print("Handle Cancel Logic here")
}))

present(refreshAlert, animated: true, completion: nil)

Swift 5.3 update:

let refreshAlert = UIAlertController(title: "Refresh", message: "All data will be lost.", preferredStyle: UIAlertController.Style.alert)

refreshAlert.addAction(UIAlertAction(title: "Ok", style: .default, handler: { (action: UIAlertAction!) in
      print("Handle Ok logic here")
}))

refreshAlert.addAction(UIAlertAction(title: "Cancel", style: .cancel, handler: { (action: UIAlertAction!) in
      print("Handle Cancel Logic here")
}))

present(refreshAlert, animated: true, completion: nil)

Backticks enclose template literals, previously known as template strings. Template literals are string literals that allow embedded expressions and string interpolation features.

Template literals have expressions embedded in placeholders, denoted by the dollar sign and curly brackets around an expression, i.e. ${expression}. The placeholder / expressions get passed to a function. The default function just concatenates the string.

To escape a backtick, put a backslash before it:

`\`` === '`'; => true

Use backticks to more easily write multi-line string:

console.log(`string text line 1
string text line 2`);

or

console.log(`Fifteen is ${a + b} and
not ${2 * a + b}.`);

vs. vanilla JavaScript:

console.log('string text line 1\n' +
'string text line 2');

or

console.log('Fifteen is ' + (a + b) + ' and\nnot ' + (2 * a + b) + '.');

Escape sequences:

• Unicode escapes started by \u, for example \u00A9
• Unicode code point escapes indicated by \u{}, for example \u{2F804}
• Hexadecimal escapes started by \x, for example \xA9
• Octal literal escapes started by \ and (a) digit(s), for example \251

If you're calling native apps, you need to worry about [Environment]::CurrentDirectory not about PowerShell's $PWD current directory. For various reasons, PowerShell does not set the process' current working directory when you Set-Location or Push-Location, so you need to make sure you do so if you're running applications (or cmdlets) that expect it to be set.

In a script, you can do this:

$CWD = [Environment]::CurrentDirectory

Push-Location $MyInvocation.MyCommand.Path
[Environment]::CurrentDirectory = $PWD
##  Your script code calling a native executable
Pop-Location

# Consider whether you really want to set it back:
# What if another runspace has set it in-between calls?
[Environment]::CurrentDirectory = $CWD

There's no foolproof alternative to this. Many of us put a line in our prompt function to set [Environment]::CurrentDirectory ... but that doesn't help you when you're changing the location within a script.

Two notes about the reason why this is not set by PowerShell automatically:

1. PowerShell can be multi-threaded. You can have multiple Runspaces (see RunspacePool, and the PSThreadJob module) running simultaneously withinin a single process. Each runspace has it's own $PWD present working directory, but there's only one process, and only one Environment.
2. Even when you're single-threaded, $PWD isn't always a legal CurrentDirectory (you might CD into the registry provider for instance).

If you want to put it into your prompt (which would only run in the main runspace, single-threaded), you need to use:

[Environment]::CurrentDirectory = Get-Location -PSProvider FileSystem

A more modular approach plus the ability to keep your this scope in the listeners:

var checkShift = function(fn, self) {
  return function(event) {
    if (event.shiftKey) {
      fn.call(self, event);
    }
    return true;
  };
};

$(document).on('keydown', checkShift(this.enterMode, this));

You could handle the exception directly so it would not crash your program (catching the AggregateException). You could also look at the Inner Exception, this will give you a more detailed explanation of what went wrong:

try {
    // your code 
} catch (AggregateException e) {

}

You have to edit the PHP configuration file. Find the line

error_reporting = E_ALL

and replace it with:

error_reporting = E_ALL ^ E_DEPRECATED

If you don't have access to the configuration file you can add this line to the PHP WordPress file (maybe headers.php):

error_reporting(E_ALL ^ E_DEPRECATED);

For future Googlers who choose NDK approach - i find reliable mentioned stackblur algorithm. I found C++ implementation which does not rely on SSE here - http://www.antigrain.com/__code/include/agg_blur.h.html#stack_blur_rgba32 which contains some optimizations using static tables like:

For anyone looking for a UI option using IIS Manager.

1. Open the Website in IIS Manager
2. Go To Request Filtering and open the Request Filtering Window.
3. Go to Verbs Tab and Add HTTP Verbs to "Allow Verb..." or "Deny Verb...". This allow to add the HTTP Verbs in the "Deny Verb.." Collection.

Simple solution of how to store login value in by SharedPreferences.

You can extend the MainActivity class or other class where you will store the "value of something you want to keep". Put this into writer and reader classes:

public static final String GAME_PREFERENCES_LOGIN = "Login";

Here InputClass is input and OutputClass is output class, respectively.

// This is a storage, put this in a class which you can extend or in both classes:
//(input and output)
public static final String GAME_PREFERENCES_LOGIN = "Login";

// String from the text input (can be from anywhere)
String login = inputLogin.getText().toString();

// then to add a value in InputCalss "SAVE",
SharedPreferences example = getSharedPreferences(GAME_PREFERENCES_LOGIN, 0);
Editor editor = example.edit();
editor.putString("value", login);
editor.commit();

Now you can use it somewhere else, like other class. The following is OutputClass.

SharedPreferences example = getSharedPreferences(GAME_PREFERENCES_LOGIN, 0);
String userString = example.getString("value", "defValue");

// the following will print it out in console
Logger.getLogger("Name of a OutputClass".class.getName()).log(Level.INFO, userString);

If you really want to use plain HTML (for whatever reason) and not the built-in HtmlHelper extensions, you can do it this way.

Instead of

<input id="Remember" name="Remember" type="checkbox" value="@Model.Remember" />

try using

<input id="Remember" name="Remember" type="checkbox" value="true" @(Model.Remember ? "checked" : "") />

Checkbox inputs in HTML work so that when they're checked, they send the value, and when they're not checked, they don't send anything at all (which will cause ASP.NET MVC to fallback to the default value of the field, false). Also, the value of the checkbox in HTML can be anything not just true/false, so if you really wanted, you can even use a checkbox for a string field in your model.

If you use the built-in Html.RenderCheckbox, it actually outputs two inputs: checkbox and a hidden field so that a false value is sent when the checkbox is unchecked (not just nothing). That may cause some unexpected situations, like this:

• Why does the CheckBoxFor render an additional input tag, and how can I get the value using the FormCollection?

Here's the shortest solution, based on vh. Please note that vh is not supported in some older browsers.

CSS:

div {
    width: 100%;
    height: 100vh;
}

HTML:

<div>This div is fullscreen :)</div>

In Powershell 3.0 and above there is both a Invoke-WebRequest and Invoke-RestMethod. Curl is actually an alias of Invoke-WebRequest in PoSH. I think using native Powershell would be much more appropriate than curl, but it's up to you :).

Invoke-WebRequest MSDN docs are here: https://technet.microsoft.com/en-us/library/hh849901.aspx?f=255&MSPPError=-2147217396

Invoke-RestMethod MSDN docs are here: https://technet.microsoft.com/en-us/library/hh849971.aspx?f=255&MSPPError=-2147217396

Check official git documentation:

If you use the SSH transport for connecting to remotes, it’s possible for you to have a key without a passphrase, which allows you to securely transfer data without typing in your username and password. However, this isn’t possible with the HTTP protocols – every connection needs a username and password. This gets even harder for systems with two-factor authentication, where the token you use for a password is randomly generated and unpronounceable.

Fortunately, Git has a credentials system that can help with this. Git has a few options provided in the box:

• The default is not to cache at all. Every connection will prompt you for your username and password.

• The “cache” mode keeps credentials in memory for a certain period of time. None of the passwords are ever stored on disk, and they are purged from the cache after 15 minutes.

• The “store” mode saves the credentials to a plain-text file on disk, and they never expire. This means that until you change your password for the Git host, you won’t ever have to type in your credentials again. The downside of this approach is that your passwords are stored in cleartext in a plain file in your home directory.

• If you’re using a Mac, Git comes with an “osxkeychain” mode, which caches credentials in the secure keychain that’s attached to your system account. This method stores the credentials on disk, and they never expire, but they’re encrypted with the same system that stores HTTPS certificates and Safari auto-fills.

• If you’re using Windows, you can install a helper called “Git Credential Manager for Windows.” This is similar to the “osxkeychain” helper described above, but uses the Windows Credential Store to control sensitive information. It can be found at https://github.com/Microsoft/Git-Credential-Manager-for-Windows.

You can choose one of these methods by setting a Git configuration value:

$ git config --global credential.helper cache

$ git config --global credential.helper store

https://git-scm.com/book/en/v2/Git-Tools-Credential-Storage

Here is the configuration for those trying to accomplish the original goal (wildcards all pointing to same codebase -- install nothing, dev environment ie, XAMPP)

hosts file (add an entry)

file: /etc/hosts (non-windows)

127.0.0.1   example.local

httpd.conf configuration (enable vhosts)

file: /XAMPP/etc/httpd.conf

# Virtual hosts
Include etc/extra/httpd-vhosts.conf

httpd-vhosts.conf configuration

file: XAMPP/etc/extra/httpd-vhosts.conf

<VirtualHost *:80>
    ServerAdmin [email protected]
    DocumentRoot "/path_to_XAMPP/htdocs"
    ServerName example.local
    ServerAlias *.example.local
#    SetEnv APP_ENVIRONMENT development
#    ErrorLog "logs/example.local-error_log"
#    CustomLog "logs/example.local-access_log" common
</VirtualHost>

restart apache

create pac file:

save as whatever.pac wherever you want to and then load the file in the browser's network>proxy>auto_configuration settings (reload if you alter this)

function FindProxyForURL(url, host) {
  if (shExpMatch(host, "*example.local")) {
    return "PROXY example.local";
  }
  return "DIRECT";
}

As Paddy mentioned: if you use an overload of UrlHelper.Action() that explicitly specifies the protocol to use, the generated URL will be absolute and fully qualified instead of being relative.

I wrote a blog post called How to build absolute action URLs using the UrlHelper class in which I suggest to write a custom extension method for the sake of readability:

/// <summary>
/// Generates a fully qualified URL to an action method by using
/// the specified action name, controller name and route values.
/// </summary>
/// <param name="url">The URL helper.</param>
/// <param name="actionName">The name of the action method.</param>
/// <param name="controllerName">The name of the controller.</param>
/// <param name="routeValues">The route values.</param>
/// <returns>The absolute URL.</returns>
public static string AbsoluteAction(this UrlHelper url,
    string actionName, string controllerName, object routeValues = null)
{
    string scheme = url.RequestContext.HttpContext.Request.Url.Scheme;

    return url.Action(actionName, controllerName, routeValues, scheme);
}

You can then simply use it like that in your view:

@Url.AbsoluteAction("Action", "Controller")

I found this as a good example for this question:

    class Publication {

    private String title;

    public Publication(String title) {
        this.title = title;
    }

    public String getDetails() {
        return "title=\"" + title + "\"";
    }

}

class Newspaper extends Publication {

    private String source;

    public Newspaper(String title, String source) {
        super(title);
        this.source = source;
    }

    @Override
    public String getDetails() {
        return super.getDetails() + ", source=\"" + source + "\"";
    }
}

class Article extends Publication {

    private String author;

    public Article(String title, String author) {
        super(title);
        this.author = author;
    }

    @Override
    public String getDetails() {
        return super.getDetails() + ", author=\"" + author + "\"";
    }

}

class Announcement extends Publication {

    private int daysToExpire;

    public Announcement(String title, int daysToExpire) {
        super(title);
        this.daysToExpire = daysToExpire;
    }

    @Override
    public String getDetails() {
        return super.getDetails() + ", daysToExpire=" + daysToExpire;
    }

}

Your class Delivery has no access modifier, which means it defaults to internal. If you then try to expose a property of that type as public, it won't work. Your type (class) needs to have the same, or higher access as your property.

More about access modifiers: http://msdn.microsoft.com/en-us/library/ms173121.aspx

This works too: class = "browser-default"

There is an much easier way to do this.

Just open the file inspector and select a "global tint".

You can also set an app’s tint color in Interface Builder. The Global Tint menu in the Interface Builder Document section of the File inspector lets you open the Colors window or choose a specific color.

Also see:

https://developer.apple.com/library/ios/documentation/userexperience/conceptual/TransitionGuide/AppearanceCustomization.html

Just change Property from property of control: AutoSizeColumnsMode:Fill

OR By code

dataGridView1.AutoSizeColumnsMode=DataGridViewAutoSizeColumnsMode.Fill;

This is really just an expansion of BBB's answer which lead to to get my experiment working.

This script will simply create a file /tmp/testfile when you click on the button that says "Open Script".

This requires 3 files.

1. The actual HTML Website with a button.
2. A php script which executes the script
3. A Script

The File Tree:

root@test:/var/www/html# tree testscript/
testscript/
+-- index.html
+-- testexec.php
+-- test.sh

1. The main WebPage:

root@test:/var/www/html# cat testscript/index.html
<form action="/testscript/testexec.php">
    <input type="submit" value="Open Script">
</form>

2. The PHP Page that runs the script and redirects back to the main page:

root@test:/var/www/html# cat testscript/testexec.php
<?php
shell_exec("/var/www/html/testscript/test.sh");
header('Location: http://192.168.1.222/testscript/index.html?success=true');
?>

3. The Script :

root@test:/var/www/html# cat testscript/test.sh

#!/bin/bash

touch /tmp/testfile

The answer of the equation is rounded to the next smaller integer or float with .0 as decimal point.

>>>print 5//2
2
>>> print 5.0//2
2.0
>>>print 5//2.0
2.0
>>>print 5.0//2.0
2.0

From the docs page, notice they have these helpful headers

http://momentjs.com/docs/#/get-set/weekday/
(I didn't see them at first)

With header sections for:

• Date of Month
• Day of Week
• etc

.

  var now = moment();
  var day  = now.day();
  var date = now.date(); // Number

For people using Tiny Core Linux, you also need to install libtool-dev as it has the *.m4 files needed for libtoolize.

I use a classical javascript to set value to hidden input

$scope.SetPersonValue = function (PersonValue)
{
    document.getElementById('TypeOfPerson').value = PersonValue;
    if (PersonValue != 'person')
    {
        document.getElementById('Discount').checked = false;
        $scope.isCollapsed = true;
    }
    else
    {
        $scope.isCollapsed = false;
    }
}

If you are using the normal login whilst entering the username and password between the protocol and the domain this is simpler. It also works with and without login.

Sample Url: http://user:[email protected]/url

URL url = new URL("http://user:[email protected]/url");
URLConnection urlConnection = url.openConnection();

if (url.getUserInfo() != null) {
    String basicAuth = "Basic " + new String(new Base64().encode(url.getUserInfo().getBytes()));
    urlConnection.setRequestProperty("Authorization", basicAuth);
}

InputStream inputStream = urlConnection.getInputStream();

Please note in the comment, from valerybodak, below how it is done in an Android development environment.

Try:

$("#"+styleTarget).css({ 'font-size': $(this).val() });

By putting the value in quotes, it becomes a string, and "+$(this).val()+"px is definitely not close to a font value. There are a couple of ways of setting the style properties of an element:

Using a map:

$("#elem").css({
    fontSize: 20
});

Using key and value parameters:

All of these are valid.

$("#elem").css("fontSize", 20);
$("#elem").css("fontSize", "20px");
$("#elem").css("font-size", "20");
$("#elem").css("font-size", "20px");

You can replace "fontSize" with "font-size" but it will have to be quoted then.

Judging by your above comment, you're OK doing this with jQuery — here goes:

// for every element in the body tag
$("*", "body").each(function() {
  // parse out its computed font size, and see if it is less than 12
  if ( parseInt($(this).css("font-size"), 10) < 12 )
    // if so, then manually give it a CSS property of 12px
    $(this).css("font-size", "12px")
});

A cleaner way to do this might be to have a "min-font" class in your CSS that sets font-size: 12px, and just add the class instead:

$("*", "body").each(function() {
  if ( parseInt($(this).css("font-size"), 10) < 12 )
    $(this).addClass("min-font")
});

This clearly is a bad case of controller logic in a view. It would be better to do this in a controller and return the desired view.

[ChildActionOnly]
public ActionResult Results() 
{
    EnumerableRowCollection<DataRow> custs = ViewBag.Customers;
    bool anyRows = custs.Any();

    if(anyRows == false)
    {
        return View("NoResults");
    }
    else
    {
        return View("OtherView");
    }
}

Modify NoResults.cshtml to a Partial.

And call this as a Partial view in the parent view

@Html.Partial("Results")

You might have to pass the Customer collection as a model to the Result action or in a ViewDataDictionary due to reasons explained here: Can't access ViewBag in a partial view in ASP.NET MVC3

The ChildActionOnly attribute will make sure you cannot go to this page by navigating and that this view must be rendered as a partial, thus by a parent view. cfr: Using ChildActionOnly in MVC

In C, a string is actually stored as an array of characters, so the 'string pointer' is pointing to the first character. For instance,

char myString[] = "This is some text";

You can access any character as a simple char by using myString as an array, thus:

char myChar = myString[6];
printf("%c\n", myChar); // Prints s

Hope this helps! David

if using /bin/sh you can use:

EDIT: First check, if you did not run out of disk-space, before resolving to the configuration-related resolution.

You seem to have a too low maximum size for your innodb_data_file_path in your my.cnf, In this example

innodb_data_file_path = ibdata1:10M:autoextend:max:512M

you cannot host more than 512MB of data in all innodb tables combined.

Maybe you should switch to an innodb-per-table scheme using innodb_file_per_table.

The real reason because set does not work is the fact, that it uses the hash function to distinguish different values. This means that sets only allows hashable objects. Why a list is not hashable is already pointed out.

It is easier with Kotlin using for-in loop:

for (childView in ll.children) {
     //childView is a child of ll         
}

Here ll is id of LinearLayout defined in layout XML.

Note: Even though this is the accepted answer, the answer below is more accurate and is currently supported in all browsers if you have the option of using a background image.

No, there is no CSS only way to do this in both directions. You could add

.fillwidth {
    min-width: 100%;
    height: auto;
}

To the an element to always have it 100% width and automatically scale the height to the aspect ratio, or the inverse:

.fillheight {
    min-height: 100%; 
    width: auto;
}

to always scale to max height and relative width. To do both, you will need to determine if the aspect ratio is higher or lower than it's container, and CSS can't do this.

The reason is that CSS does not know what the page looks like. It sets rules beforehand, but only after that it is that the elements get rendered and you know exactly what sizes and ratios you're dealing with. The only way to detect that is with JavaScript.

Although you're not looking for a JS solution I'll add one anyway if someone might need it. The easiest way to handle this with JavaScript is to add a class based on the difference in ratio. If the width-to-height ratio of the box is greater than that of the image, add the class "fillwidth", else add the class "fillheight".

$('div').each(function() {_x000D_
  var fillClass = ($(this).height() > $(this).width()) _x000D_
    ? 'fillheight'_x000D_
    : 'fillwidth';_x000D_
  $(this).find('img').addClass(fillClass);_x000D_
});

.fillwidth { _x000D_
  width: 100%; _x000D_
  height: auto; _x000D_
}_x000D_
.fillheight { _x000D_

Save the following program as print.py:

#!/usr/bin/python3
print('Hello World')

Then in the terminal type:

chmod +x print.py
./print.py

To elaborate on @Bakuriu's answer above, I've found that this enables me to catch a runtime warning in a similar fashion to how I would catch an error warning, printing out the warning nicely:

import warnings

with warnings.catch_warnings():
    warnings.filterwarnings('error')
    try:
        answer = 1 / 0
    except Warning as e:
        print('error found:', e)

You will probably be able to play around with placing of the warnings.catch_warnings() placement depending on how big of an umbrella you want to cast with catching errors this way.

//This delegate can be used to point to methods
//which return void and take a string.
public delegate void MyDelegate(string foo);

//This event can cause any method which conforms
//to MyEventHandler to be called.
public event MyDelegate MyEvent;

//Here is some code I want to be executed
//when SomethingHappened fires.
void MyEventHandler(string foo)
{
    //Do some stuff
}

//I am creating a delegate (pointer) to HandleSomethingHappened
//and adding it to SomethingHappened's list of "Event Handlers".
myObj.MyEvent += new MyDelegate (MyEventHandler);

How do Python's any and all functions work?

any and all take iterables and return True if any and all (respectively) of the elements are True.

>>> any([0, 0.0, False, (), '0']), all([1, 0.0001, True, (False,)])
(True, True)            #   ^^^-- truthy non-empty string
>>> any([0, 0.0, False, (), '']), all([1, 0.0001, True, (False,), {}])
(False, False)                                                #   ^^-- falsey

If the iterables are empty, any returns False, and all returns True.

>>> any([]), all([])
(False, True)

I was demonstrating all and any for students in class today. They were mostly confused about the return values for empty iterables. Explaining it this way caused a lot of lightbulbs to turn on.

Shortcutting behavior

They, any and all, both look for a condition that allows them to stop evaluating. The first examples I gave required them to evaluate the boolean for each element in the entire list.

(Note that list literal is not itself lazily evaluated - you could get that with an Iterator - but this is just for illustrative purposes.)

Here's a Python implementation of any and all:

def any(iterable):
    for i in iterable:
        if i:
            return True
    return False # for an empty iterable, any returns False!

def all(iterable):
    for i in iterable:
        if not i:
            return False
    return True  # for an empty iterable, all returns True!

Of course, the real implementations are written in C and are much more performant, but you could substitute the above and get the same results for the code in this (or any other) answer.

all

all checks for elements to be False (so it can return False), then it returns True if none of them were False.

>>> all([1, 2, 3, 4])                 # has to test to the end!
True
>>> all([0, 1, 2, 3, 4])              # 0 is False in a boolean context!
False  # ^--stops here!
>>> all([])
True   # gets to end, so True!

any

The way any works is that it checks for elements to be True (so it can return True), then it returnsFalseif none of them wereTrue`.

>>> any([0, 0.0, '', (), [], {}])     # has to test to the end!
False
>>> any([1, 0, 0.0, '', (), [], {}])  # 1 is True in a boolean context!
True   # ^--stops here!
>>> any([])
False   # gets to end, so False!

I think if you keep in mind the short-cutting behavior, you will intuitively understand how they work without having to reference a Truth Table.

Evidence of all and any shortcutting:

First, create a noisy_iterator:

def noisy_iterator(iterable):
    for i in iterable:
        print('yielding ' + repr(i))
        yield i

and now let's just iterate over the lists noisily, using our examples:

>>> all(noisy_iterator([1, 2, 3, 4]))
yielding 1
yielding 2
yielding 3
yielding 4
True
>>> all(noisy_iterator([0, 1, 2, 3, 4]))
yielding 0
False

We can see all stops on the first False boolean check.

And any stops on the first True boolean check:

>>> any(noisy_iterator([0, 0.0, '', (), [], {}]))
yielding 0
yielding 0.0
yielding ''
yielding ()
yielding []
yielding {}
False
>>> any(noisy_iterator([1, 0, 0.0, '', (), [], {}]))
yielding 1
True

The source

Let's look at the source to confirm the above.

Here's the source for any:

static PyObject *
builtin_any(PyObject *module, PyObject *iterable)
{
    PyObject *it, *item;
    PyObject *(*iternext)(PyObject *);
    int cmp;

    it = PyObject_GetIter(iterable);
    if (it == NULL)
        return NULL;
    iternext = *Py_TYPE(it)->tp_iternext;

    for (;;) {
        item = iternext(it);
        if (item == NULL)
            break;
        cmp = PyObject_IsTrue(item);
        Py_DECREF(item);
        if (cmp < 0) {
            Py_DECREF(it);
            return NULL;
        }
        if (cmp > 0) {
            Py_DECREF(it);
            Py_RETURN_TRUE;
        }
    }
    Py_DECREF(it);
    if (PyErr_Occurred()) {
        if (PyErr_ExceptionMatches(PyExc_StopIteration))
            PyErr_Clear();
        else
            return NULL;
    }
    Py_RETURN_FALSE;
}

And here's the source for all:

static PyObject *
builtin_all(PyObject *module, PyObject *iterable)
{
    PyObject *it, *item;
    PyObject *(*iternext)(PyObject *);
    int cmp;

    it = PyObject_GetIter(iterable);
    if (it == NULL)
        return NULL;
    iternext = *Py_TYPE(it)->tp_iternext;

    for (;;) {
        item = iternext(it);
        if (item == NULL)
            break;
        cmp = PyObject_IsTrue(item);
        Py_DECREF(item);
        if (cmp < 0) {
            Py_DECREF(it);
            return NULL;
        }
        if (cmp == 0) {
            Py_DECREF(it);
            Py_RETURN_FALSE;
        }
    }
    Py_DECREF(it);
    if (PyErr_Occurred()) {
        if (PyErr_ExceptionMatches(PyExc_StopIteration))
            PyErr_Clear();
        else
            return NULL;
    }
    Py_RETURN_TRUE;
}

What about -mmin?

find /var/www/html/audio -daystart -maxdepth 1 -mmin +59 -type f -name "*.mp3" \
    -exec rm -f {} \;

From man find:

-mmin n
        File's data was last modified n minutes ago.

Also, make sure to test this first!

... -exec echo rm -f '{}' \;
          ^^^^ Add the 'echo' so you just see the commands that are going to get
               run instead of actual trying them first.

Try to open the Android Sdk manager and the path would be displayed on the status bar.

Support for the extended ternary operator was added in Twig 1.12.0.

1. If foo echo yes else echo no:

   {{ foo ? 'yes' : 'no' }}
   

2. If foo echo it, else echo no:

   {{ foo ?: 'no' }}
   

   or

   {{ foo ? foo : 'no' }}
   

3. If foo echo yes else echo nothing:

   {{ foo ? 'yes' }}
   

   or

   {{ foo ? 'yes' : '' }}
   

4. Returns the value of foo if it is defined and not null, no otherwise:

   {{ foo ?? 'no' }}
   

5. Returns the value of foo if it is defined (empty values also count), no otherwise:

   {{ foo|default('no') }}
   

Facebook sharing from a share dialog fails even with @Matthieu answer (which is 100% correct for the rest of social URLs). I had to add a set of URL i reversed from Facebook SDK.

Just make the top-level layout a ScrollView:

        <!-- everything you already have -->

    </TableLayout>

I'm here in general only to find out that through dict it is necessary to work inside setattr XD

So far as my observation goes, any answer posted here can have unexpected side effects.

In ES2015-compatible enviroment, you can avoid any side effects by using WeakMap.

const id = (() => {
    let currentId = 0;
    const map = new WeakMap();

    return (object) => {
        if (!map.has(object)) {
            map.set(object, ++currentId);
        }

        return map.get(object);
    };
})();

id({}); //=> 1

class CurrentValue:

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

    def set_val(self, k):
        self.value = k

    def get_val(self):
        return self.value


class AddValue:

    def av(self, ocv):
        print('Before:', ocv.get_val())
        num = int(input('Enter number to add : '))
        nnum = num + ocv.get_val()
        ocv.set_val(nnum)
        print('After add :', ocv.get_val())


cvo = CurrentValue(5)

avo = AddValue()

avo.av(cvo)

We define 2 classes, CurrentValue and AddValue We define 3 methods in the first class One init in order to give to the instance variable self.value an initial value A set_val method where we set the self.value to a k A get_val method where we get the valuue of self.value We define one method in the second class A av method where we pass as parameter(ovc) an object of the first class We create an instance (cvo) of the first class We create an instance (avo) of the second class We call the method avo.av(cvo) of the second class and pass as an argument the object we have already created from the first class. So by this way I would like to show how it is possible to call a method of a class from another class.

I am sorry for any inconvenience. This will not happen again.

One reason you get this error is that your local postgres database shuts down when you restart your computer. In a new terminal window, simply type:

$psql -h localhost 

to restart the server.

Several of these things did not work for me... however, this did. Might help someone else in the future. Here is the CSS:

    .img-area {
     display: block;
     padding: 0px 0 0 0px;
     text-indent: 0;

Here's my two cent's worth: I've previously implemented an IdFactory class that created IDs in the format [host name]-[application start time]-[current time]-[discriminator]. This largely guaranteed that IDs were unique across JVM instances whilst keeping the IDs readable (albeit quite long). Here's the code in case it's of any use:

public class IdFactoryImpl implements IdFactory {
  private final String hostName;
  private final long creationTimeMillis;
  private long lastTimeMillis;
  private long discriminator;

  public IdFactoryImpl() throws UnknownHostException {
    this.hostName = InetAddress.getLocalHost().getHostAddress();
    this.creationTimeMillis = System.currentTimeMillis();
    this.lastTimeMillis = creationTimeMillis;
  }

  public synchronized Serializable createId() {
    String id;
    long now = System.currentTimeMillis();

    if (now == lastTimeMillis) {
      ++discriminator;
    } else {
      discriminator = 0;
    }

    // creationTimeMillis used to prevent multiple instances of the JVM
    // running on the same host returning clashing IDs.
    // The only way a clash could occur is if the applications started at
    // exactly the same time.
    id = String.format("%s-%d-%d-%d", hostName, creationTimeMillis, now, discriminator);
    lastTimeMillis = now;

    return id;
  }

  public static void main(String[] args) throws UnknownHostException {
    IdFactory fact = new IdFactoryImpl();

    for (int i=0; i<1000; ++i) {
      System.err.println(fact.createId());
    }
  }
}

Create your repository in git hub

Allow to track your project by GIT

1. using CMD go to folder where your project file is kept->cd /automation/xyz/codebase check for git intialization with command git status If you get this error message: fatal: Not a git repository (or any of the parent directories): .git, that means the folder you are currently in is not being tracked by git. In that case, initialize git inside your project folder by typing git init, then going through the process of adding and committing your project.

If you get another error message, read carefully what it says. Is it saying git isn't installed on your computer by saying that the word 'git' is not recognized? Is it saying that you're already in a folder or sub-folder where git is initialized? Google your error and/or output to understand it, and to figure out how to fix it.

now run following command

echo "your git hub repository name" >> README.md git init git add README.md git commit -m "first commit" git remote add origin https:// #

above block you will get when first time you are opening your repository

If error occurs or nothing happens after last command run"git push -u origin master" dont worry

go to folder where code is available and through git extention push it to git [URL], branch

Based on Haim's answer I created a PHP code to test and display all the differences between two databases. This will also display if a table is present in source or test databases. You have to change with your details the <> variables content.

There is a jquery plugin for this. It scrolls document to a specific element, so that it would be perfectly in the middle of viewport. It also supports animation easings so that the scroll effect would look super smooth. Check out AnimatedScroll.js.

Since everyone answering this question has problems due to the 500 video limit here's an alternate solution using youtube_dl in Python 3. Also, no API key is needed.

1. Install youtube_dl: sudo pip3 install youtube-dl
2. Find out your target channel's channel id. The ID is going to start with UC. Replace the C for Channel with U for Upload (i.e. UU...), this is the upload playlist.
3. Use the playlist downloader feature from youtube-dl. Ideally you do NOT want to download every video in the playlist which is the default, but only the metadata.

Example (warning -- takes tens of minutes):

import youtube_dl, pickle

             # UCVTyTA7-g9nopHeHbeuvpRA is the channel id (1517+ videos)
PLAYLIST_ID = 'UUVTyTA7-g9nopHeHbeuvpRA'  # Late Night with Seth Meyers

with youtube_dl.YoutubeDL({'ignoreerrors': True}) as ydl:

    playd = ydl.extract_info(PLAYLIST_ID, download=False)

    with open('playlist.pickle', 'wb') as f:
        pickle.dump(playd, f, pickle.HIGHEST_PROTOCOL)

    vids = [vid for vid in playd['entries'] if 'A Closer Look' in vid['title']]
    print(sum('Trump' in vid['title'] for vid in vids), '/', len(vids))

Yes, they're both JavaScript, you can use whichever functions are appropriate for the situation.

In this case you can just put the code in a document.ready handler, like this:

$(function() {
  var canvas = document.getElementById("canvas");
  if (canvas.getContext) {
    var ctx = canvas.getContext("2d");

    ctx.fillStyle = "rgb(200,0,0)";
    ctx.fillRect (10, 10, 55, 50);

    ctx.fillStyle = "rgba(0, 0, 200, 0.5)";
    ctx.fillRect (30, 30, 55, 50);
  }
});

You have to put all your assets in app/public folder, and to access them from your views you can use asset() helper method.

Ex. you can retrieve assets/images/image.png in your view as following:

<img src="{{asset('assets/images/image.png')}}">

class Person:

def init(self,name,age,weight,sex,mob_no,place):

self.name = str(name)
self.age = int(age)
self.weight = int(weight)
self.sex = str(sex)
self.mob_no = int(mob_no)
self.place = str(place)

Creating an instance to class Person

p1 = Person(Muthuswamy,50,70,Male,94*****23,India)

print(p1.name)

print(p1.place)

Output

Muthuswamy

India

You may set the timeout either globally for entire server:

var server = app.listen();
server.setTimeout(500000);

or just for specific route:

app.post('/xxx', function (req, res) {
   req.setTimeout(500000);
});

                             download: fname
                         })[0].click();

If attr method not working in Firefox You can also use javaScript setAttribute method

A great search engine for special characters that I recenetly found: amp-what?

You can even search by object name, like "arrow", "chess", etc...

You can trigger any of the events with a direct call to them, like this:

$(function() {
    $('item').keydown();
    $('item').keypress();
    $('item').keyup();
    $('item').blur();
});

Does that do what you're trying to do?

You should probably also trigger .focus() and potentially .change()

If you want to trigger the key-events with specific keys, you can do so like this:

$(function() {
    var e = $.Event('keypress');
    e.which = 65; // Character 'A'
    $('item').trigger(e);
});

There is some interesting discussion of the keypress events here: jQuery Event Keypress: Which key was pressed?, specifically regarding cross-browser compatability with the .which property.

The calculated column trick is widely known as a "nullbuster"; my notes credit Steve Kass:

CREATE TABLE dupNulls (
pk int identity(1,1) primary key,
X  int NULL,
nullbuster as (case when X is null then pk else 0 end),
CONSTRAINT dupNulls_uqX UNIQUE (X,nullbuster)
)

Another option I've just run across is bashplotlib. Here's an example run on (roughly) the same data as my eplot example:

You are trying to call DeckOfCards::shuffle with a deckOfCards parameter:

deckOfCards cardDeck; // create DeckOfCards object
cardDeck.shuffle(cardDeck); // shuffle the cards in the deck

But the method takes a vector<Card>&:

void deckOfCards::shuffle(vector<Card>& deck)

The compiler error messages are quite clear on this. I'll paraphrase the compiler as it talks to you.

Error:

[Error] no matching function for call to 'deckOfCards::shuffle(deckOfCards&)'

Paraphrased:

Hey, pal. You're trying to call a function called shuffle which apparently takes a single parameter of type reference-to-deckOfCards, but there is no such function.

Error:

[Note] candidate is:

In file included from main.cpp

[Note] void deckOfCards::shuffle(std::vector&)

Paraphrased:

I mean, maybe you meant this other function called shuffle, but that one takes a reference-tovector<something>.

Error:

[Note] no known conversion for argument 1 from 'deckOfCards' to 'std::vector&'

Which I'd be happy to call if I knew how to convert from a deckOfCards to a vector; but I don't. So I won't.

You can use this plugin timer_builder

timer_builder widget that rebuilds itself on scheduled, periodic, or dynamically generated time events.

Examples

Periodic rebuild

import 'package:timer_builder/timer_builder.dart';

class ClockWidget extends StatelessWidget {

  @override
  Widget build(BuildContext context) {
    return TimerBuilder.periodic(Duration(seconds: 1),
      builder: (context) {
        return Text("${DateTime.now()}");
      }
    );
  }
  
}

Rebuild on a schedule

import 'package:timer_builder/timer_builder.dart';

class StatusIndicator extends StatelessWidget {

  final DateTime startTime;
  final DateTime endTime;
  
  StatusIndicator(this.startTime, this.endTime);
  
  @override
  Widget build(BuildContext context) {
    return TimerBuilder.scheduled([startTime, endTime],
      builder: (context) {
        final now = DateTime.now();
        final started = now.compareTo(startTime) >= 0;
        final ended = now.compareTo(endTime) >= 0;
        return Text(started ? ended ? "Ended": "Started": "Not Started");
      }
    );
  }
  
}

Two different approaches:

1. Pass in your return values by pointer, and modify them inside the function. You declare your function as void, but it's returning via the values passed in as pointers.
2. Define a struct that aggregates your return values.

I think that #1 is a little more obvious about what's going on, although it can get tedious if you have too many return values. In that case, option #2 works fairly well, although there's some mental overhead involved in making specialized structs for this purpose.

INSERT INTO ... ON DUPLICATE KEY UPDATE will only work for MYSQL, not for SQL Server.

for SQL server, the way to work around this is to first declare a temp table, insert value to that temp table, and then use MERGE

Like this:

declare @Source table
(
name varchar(30),
age decimal(23,0)
)

insert into @Source VALUES
('Helen', 24),
('Katrina', 21),
('Samia', 22),
('Hui Ling', 25),
('Yumie', 29);


MERGE beautiful  AS Tg
using  @source as Sc
on tg.namet=sc.name 

when matched then update 
set tg.age=sc.age

when not matched then 
insert (name, age) VALUES
(SC.name, sc.age);

Please, see oficial encode() and decode() documentation from codecs library. utf-8 is the default encoding for the functions, but there are severals standard encodings in Python 3, like latin_1 or utf_32.

If you are at a certain branch mybranch, just go ahead and git checkout commit_hash. Then you can return to your branch by git checkout mybranch. I had the same game bisecting a bug today :) Also, you should know about git bisect.

IMHO the method UserForm_Initialize should remain private bacause it is event handler for Initialize event of the UserForm.

This event handler is called when new instance of the UserForm is created. In this even handler u can initialize the private members of UserForm1 class.

Example:

Standard module code:

Option Explicit

Public Sub Main()
  Dim myUserForm As UserForm1

  Set myUserForm = New UserForm1
  myUserForm.Show

End Sub

User form code:

Option Explicit

Private m_initializationDate As Date

Private Sub UserForm_Initialize()
  m_initializationDate = VBA.DateTime.Date
  MsgBox "Hi from UserForm_Initialize event handler.", vbInformation
End Sub

I have used JTextArea for multiline JLabels.

JTextArea textarea = new JTextArea ("1\n2\n3\n"+"4\n");

http://docs.oracle.com/javase/7/docs/api/javax/swing/JTextArea.html

Check the type property. Would that suffice?

import org.apache.commons.lang3.StringUtils;

String stringToPad = "10";
int maxPadLength = 10;
String paddingCharacter = " ";

StringUtils.leftPad(stringToPad, maxPadLength, paddingCharacter)

Way better than Guava imo. Never seen a single enterprise Java project that uses Guava but Apache String Utils is incredibly common.

Using the START command to run each program should get you what you need:

START "title" [/D path] [options] "command" [parameters]

Every START invocation runs the command given in its parameter and returns immediately, unless executed with a /WAIT switch.

That applies to command-line apps. Apps without command line return immediately anyway, so to be sure, if you want to run all asynchronously, use START.

Python 2 uses ascii as the default encoding for source files, which means you must specify another encoding at the top of the file to use non-ascii unicode characters in literals. Python 3 uses utf-8 as the default encoding for source files, so this is less of an issue.

See: http://docs.python.org/tutorial/interpreter.html#source-code-encoding

To enable utf-8 source encoding, this would go in one of the top two lines:

# -*- coding: utf-8 -*-

The above is in the docs, but this also works:

# coding: utf-8

Additional considerations:

• The source file must be saved using the correct encoding in your text editor as well.

• In Python 2, the unicode literal must have a u before it, as in s.replace(u"Â ", u"") But in Python 3, just use quotes. In Python 2, you can from __future__ import unicode_literals to obtain the Python 3 behavior, but be aware this affects the entire current module.

• s.replace(u"Â ", u"") will also fail if s is not a unicode string.

• string.replace returns a new string and does not edit in place, so make sure you're using the return value as well

Swift4 Code

Try this some new extension methods:

import UIKit

extension UIView {

    fileprivate struct AssociatedObjectKeys {
        static var tapGestureRecognizer = "MediaViewerAssociatedObjectKey_mediaViewer"
    }

    fileprivate typealias Action = (() -> Void)?


    fileprivate var tapGestureRecognizerAction: Action? {
        set {
            if let newValue = newValue {
                // Computed properties get stored as associated objects
                objc_setAssociatedObject(self, &AssociatedObjectKeys.tapGestureRecognizer, newValue, objc_AssociationPolicy.OBJC_ASSOCIATION_RETAIN)
            }
        }
        get {
            let tapGestureRecognizerActionInstance = objc_getAssociatedObject(self, &AssociatedObjectKeys.tapGestureRecognizer) as? Action
            return tapGestureRecognizerActionInstance
        }
    }


    public func addTapGestureRecognizer(action: (() -> Void)?) {
        self.isUserInteractionEnabled = true
        self.tapGestureRecognizerAction = action
        let tapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(handleTapGesture))
        self.addGestureRecognizer(tapGestureRecognizer)
    }


    @objc fileprivate func handleTapGesture(sender: UITapGestureRecognizer) {
        if let action = self.tapGestureRecognizerAction {
            action?()
        } else {
            print("no action")
        }
    }

}

Now whenever we want to add a UITapGestureRecognizer to a UIView or UIView subclass like UIImageView, we can do so without creating associated functions for selectors!

Usage:

 profile_ImageView.addTapGestureRecognizer {
        print("image tapped")
    }

You could use a bit of jQuery:

$('input:radio').click(function(){
    $('label#' + $(this).attr('id')).toggleClass('checkedClass'); // checkedClass is defined in your CSS
});

You'd need to make sure your checked radio buttons have the correct class on page load as well.

use RowDataBound function to bind data with a perticular cell, and to get control use (ASP Control Name like DropDownList) GridView.FindControl("Name of Control")

A variation of the first answer that I found useful

Open your command prompt and enter (you dont have to be logged into your mysql server)

mysqldump -hlocalhost -u<root> -p<password>  <dbname>  --compact --no-data > </path_to_mydump/>mysql.dmp

In addition to erickson's suggestions, there's also jna, which allows you to call native libraries without using jni. It's shockingly easy to use, and I've used it on a couple of projects with great success.

The only caveat is that it's slower than jni, so if you're doing this to a very large number of files that might be an issue for you.

(Editing to add example)

Here's a complete jna chmod example:

import com.sun.jna.Library;
import com.sun.jna.Native;

public class Main {
    private static CLibrary libc = (CLibrary) Native.loadLibrary("c", CLibrary.class);

    public static void main(String[] args) {
        libc.chmod("/path/to/file", 0755);
    }
}

interface CLibrary extends Library {
    public int chmod(String path, int mode);
}

As stated in MSDN (eg. https://msdn.microsoft.com/en-us/library/system.diagnostics.eventlog(v=vs.110).aspx ), checking an non existing source and creating a source requires admin privilege.

It is however possible to use the source "Application" without. In my test under Windows 2012 Server r2, I however get the following log entry using "Application" source:

The description for Event ID xxxx from source Application cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer. If the event originated on another computer, the display information had to be saved with the event. The following information was included with the event: {my event entry message} the message resource is present but the message is not found in the string/message table

I defined the following method to create the source:

    private string CreateEventSource(string currentAppName)
    {
        string eventSource = currentAppName;
        bool sourceExists;
        try
        {
            // searching the source throws a security exception ONLY if not exists!
            sourceExists = EventLog.SourceExists(eventSource);
            if (!sourceExists)
            {   // no exception until yet means the user as admin privilege
                EventLog.CreateEventSource(eventSource, "Application");
            }
        }
        catch (SecurityException)
        {
            eventSource = "Application";
        }

        return eventSource;
    }

I am calling it with currentAppName = AppDomain.CurrentDomain.FriendlyName

It might be possible to use the EventLogPermission class instead of this try/catch but not sure we can avoid the catch.

It is also possible to create the source externally, e.g in elevated Powershell:

New-EventLog -LogName Application -Source MyApp

Then, using 'MyApp' in the method above will NOT generate exception and the EventLog can be created with that source.

There's one more "hack" by using HTTP Referer (we asume that browser window was closed current referer's domain name and curent page's domain name do not match):

session_start();
$_SESSION['somevariable'] = 'somevalue';

if(parse_url($_SERVER["HTTP_REFERER"], PHP_URL_HOST) != $_SERVER["SERVER_NAME"]){
    session_destroy();
}

This also has some drawbacks, but it helped me few times.

For an example if you want to have a loop that stopped when it has counted all of the people in a group. We will consider the value X to be equal to the number of the people in the group, and the counter will be used to count all of the people in the group. To write the

while(!condition)

the code will be:

int x = people;

int counter = 0;

while(x != counter)

{

counter++;

}

return 0;

You can use JavaScript to do this, with onClick method. This maybe helps CSS3 transition click event

You may just want:

Dim regDate As Date = Date.Today()

It's caused by n % x, when x is 0. You should have x start at 2 instead. You should not use floating point here at all, since you only need integer operations.

General notes:

1. Try to format your code better. Focus on using a consistent style. E.g. you have one else that starts immediately after a if brace (not even a space), and another with a newline in between.
2. Don't use globals unless necessary. There is no reason for q to be global.
3. Don't return without a value in a non-void (int) function.

Found these docu on the google docu pages:

• row --- int --- top row of the range
• column --- int--- leftmost column of the range
• optNumRows --- int --- number of rows in the range.
• optNumColumns --- int --- number of columns in the range

In your example, you would get (if you picked the 3rd row) "C3:O3", cause C --> O is 12 columns

edit

Using the example on the docu:

// The code below will get the number of columns for the range C2:G8
// in the active spreadsheet, which happens to be "4"
var count = SpreadsheetApp.getActiveSheet().getRange(2, 3, 6, 4).getNumColumns(); Browser.msgBox(count);

The values between brackets:
2: the starting row = 2
3: the starting col = C
6: the number of rows = 6 so from 2 to 8
4: the number of cols = 4 so from C to G

So you come to the range: C2:G8

If you put something like this in your .ssh/config:

Host githost
HostName git.host.de
Port 4019
User root

then you should be able to use the basic syntax:

git push githost:/var/cache/git/project.git master

If you want to take some shortcuts you can use Apache Commons IO:

import org.apache.commons.io.FileUtils;

String data = FileUtils.readFileToString(new File("..."), "UTF-8");
System.out.println(data);

:-)

use

import console
(width, height) = console.getTerminalSize()

print "Your terminal's width is: %d" % width

EDIT: oh, I'm sorry. That's not a python standard lib one, here's the source of console.py (I don't know where it's from).

The module seems to work like that: It checks if termcap is available, when yes. It uses that; if no it checks whether the terminal supports a special ioctl call and that does not work, too, it checks for the environment variables some shells export for that. This will probably work on UNIX only.

def getTerminalSize():
    import os
    env = os.environ
    def ioctl_GWINSZ(fd):
        try:
            import fcntl, termios, struct, os
            cr = struct.unpack('hh', fcntl.ioctl(fd, termios.TIOCGWINSZ,
        '1234'))
        except:
            return
        return cr
    cr = ioctl_GWINSZ(0) or ioctl_GWINSZ(1) or ioctl_GWINSZ(2)
    if not cr:
        try:
            fd = os.open(os.ctermid(), os.O_RDONLY)
            cr = ioctl_GWINSZ(fd)
            os.close(fd)
        except:
            pass
    if not cr:
        cr = (env.get('LINES', 25), env.get('COLUMNS', 80))

        ### Use get(key[, default]) instead of a try/catch
        #try:
        #    cr = (env['LINES'], env['COLUMNS'])
        #except:
        #    cr = (25, 80)
    return int(cr[1]), int(cr[0])

I was unable to get Pavel's answer working as in when posting to a Web.Api application.

The issue appears to be with the deleting of the headers.

headersGetter();
delete headers['Content-Type'];

In order to ensure the browsers was allowed to default the Content-Type along with the boundary parameter, I needed to set the Content-Type to undefined. Using Pavel's example the boundary was never being set resulting in a 400 HTTP exception.

The key was to remove the code deleting the headers shown above and to set the headers content type to null manually. Thus allowing the browser to set the properties.

headers: {'Content-Type': undefined}

Here is a full example.

$scope.Submit = form => {
                $http({
                    method: 'POST',
                    url: 'api/FileTest',
                    headers: {'Content-Type': undefined},
                    data: {
                        FullName: $scope.FullName,
                        Email: $scope.Email,
                        File1: $scope.file
                    },
                    transformRequest: function (data, headersGetter) {
                        var formData = new FormData();
                        angular.forEach(data, function (value, key) {
                            formData.append(key, value);
                        });
                        return formData;
                    }
                })
                .success(function (data) {

                })
                .error(function (data, status) {

                });

                return false;
            }

You can strip non-digits and do a comparison. Here's a demo script:

for num in "44" "-44" "44-" "4-4" "a4" "4a" ".4" "4.4" "-4.4" "09"
do
    match=${num//[^[:digit:]]}    # strip non-digits
    match=${match#0*}             # strip leading zeros
    echo -en "$num\t$match\t"
    case $num in
        $match|-$match)    echo "Integer";;
                     *)    echo "Not integer";;
    esac
done

This is what the test output looks like:

44      44      Integer
-44     44      Integer
44-     44      Not integer
4-4     44      Not integer
a4      4       Not integer
4a      4       Not integer
.4      4       Not integer
4.4     44      Not integer
-4.4    44      Not integer
09      9       Not integer

Hash tables are O(1) average and amortized case complexity, however it suffers from O(n) worst case time complexity. [And I think this is where your confusion is]

Hash tables suffer from O(n) worst time complexity due to two reasons:

1. If too many elements were hashed into the same key: looking inside this key may take O(n) time.
2. Once a hash table has passed its load balance - it has to rehash [create a new bigger table, and re-insert each element to the table].

However, it is said to be O(1) average and amortized case because:

1. It is very rare that many items will be hashed to the same key [if you chose a good hash function and you don't have too big load balance.
2. The rehash operation, which is O(n), can at most happen after n/2 ops, which are all assumed O(1): Thus when you sum the average time per op, you get : (n*O(1) + O(n)) / n) = O(1)

Note because of the rehashing issue - a realtime applications and applications that need low latency - should not use a hash table as their data structure.

EDIT: Annother issue with hash tables: cache
Another issue where you might see a performance loss in large hash tables is due to cache performance. Hash Tables suffer from bad cache performance, and thus for large collection - the access time might take longer, since you need to reload the relevant part of the table from the memory back into the cache.

You can do that with some easy jQuery:

http://jsfiddle.net/jpXjH/6/

var elementPosition = $('#navigation').offset();

$(window).scroll(function(){
        if($(window).scrollTop() > elementPosition.top){
              $('#navigation').css('position','fixed').css('top','0');
        } else {
            $('#navigation').css('position','static');
        }    
});

To generate a shared library you need first to compile your C code with the -fPIC (position independent code) flag.

gcc -c -fPIC hello.c -o hello.o

This will generate an object file (.o), now you take it and create the .so file:

gcc hello.o -shared -o libhello.so

EDIT: Suggestions from the comments:

You can use

gcc -shared -o libhello.so -fPIC hello.c

to do it in one step. – Jonathan Leffler

I also suggest to add -Wall to get all warnings, and -g to get debugging information, to your gcc commands. – Basile Starynkevitch

If you are using Sql Server Management Studio, you can obtain a list of all schemas, create your own schema or remove an existing one by browsing to:

Thanks to Gruff Bunny and Louis' comments, I found the source of the issue.

As I use Backbone.js too, I loaded a special build of Lodash compatible with Backbone and Underscore that disables some features. In this example:

var clone = _.clone(data, true);

data[1].values.d = 'x';

• with the Normal build: _.isEqual(data, clone) === false
• with the Underscore build: _.isEqual(data, clone) === true

I just replaced the Underscore build with the Normal build in my Backbone application and the application is still working. So I can now use the Lodash .clone with the expected behaviour.

Edit 2018: the Underscore build doesn't seem to exist anymore. If you are reading this in 2018, you could be interested by this documentation (Backbone and Lodash).

I had to find the current viewController in AppDelegate. I used this

//at top of class
var window:UIWindow?

// inside my method/function
if let viewControllers = window?.rootViewController?.childViewControllers {
    for viewController in viewControllers {
        if viewController.isKindOfClass(MyViewControllerClass) {
            println("Found it!!!")
            }
        }
    }

By reading your exception , It's sure that you forgot to autowire customerService

You should autowire your customerservice .

make following changes in your controller class

@Controller
public class CustomerController{

    @Autowired
    private Customerservice customerservice;
......other code......

}

Again your service implementation class

write

@Service
public class CustomerServiceImpl implements CustomerService {
    @Autowired
    private CustomerDAO customerDAO;
......other code......

.....add transactional methods
}

If you are using hibernate make necessary changes in your applicationcontext xml file(configuration of session factory is needed).

you should autowire sessionFactory set method in your DAO mplementation

please find samle application context :

note that i am using jdbc.properties file for jdbc url and driver specification

in the manifest:

        android:screenOrientation="portrait"
        tools:ignore="LockedOrientationActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

or : in the MainActivity

@SuppressLint("SourceLockedOrientationActivity")
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

You can get other constructors with getConstructor(...).

Actually, your last example:

<div data-foobar='{"foo":"bar"}'></div>

seems to be working well (see http://jsfiddle.net/GlauberRocha/Q6kKU/).

The nice thing is that the string in the data- attribute is automatically converted to a JavaScript object. I don't see any drawback in this approach, on the contrary! One attribute is sufficient to store a whole set of data, ready to use in JavaScript through object properties.

(Note: for the data- attributes to be automatically given the type Object rather than String, you must be careful to write valid JSON, in particular to enclose the key names in double quotes).

For an updated answer you can build a forEach function in Python easily:

def forEach(list, function):
    for i, v in enumerate(list):
        function(v, i, list)

You could also adapt this to map, reduce, filter, and any other array functions from other languages or precedence you'd want to bring over. For loops are fast enough, but the boiler plate is longer than forEach or the other functions. You could also extend list to have these functions with a local pointer to a class so you could call them directly on lists as well.

Another way this could be accomplished is by using the Start-Transcript and Stop-Transcript commands, respectively before and after command execution. This would capture the entire session including commands.

Start-Transcript

Stop-Transcript

For this particular case Out-File is probably your best bet though.

The ALL_DIRECTORIES data dictionary view will have information about all the directories that you have access to. That includes the operating system path

SELECT owner, directory_name, directory_path
  FROM all_directories

The only real use case for GROUP BY without aggregation is when you GROUP BY more columns than are selected, in which case the selected columns might be repeated. Otherwise you might as well use a DISTINCT.

It's worth noting that other RDBMS's do not require that all non-aggregated columns be included in the GROUP BY. For example in PostgreSQL if the primary key columns of a table are included in the GROUP BY then other columns of that table need not be as they are guaranteed to be distinct for every distinct primary key column. I've wished in the past that Oracle did the same as it would have made for more compact SQL in many cases.

pgrep -f aa.sh 

To do something with the id, you pipe it. Here I kill all its child tasks.

pgrep aa.sh | xargs pgrep -P ${} | xargs kill

If you want to execute a command if the process is running do this

pgrep aa.sh && echo Running

I've used this with great success:

Yet another solution, pure bash + GNU readlink for easy use in following context:

ln -s "$(relpath "$A" "$B")" "$B"

Edit: Make sure that "$B" is either not existing or no softlink in that case, else relpath follows this link which is not what you want!

This works in nearly all current Linux. If readlink -m does not work at your side, try readlink -f instead. See also https://gist.github.com/hilbix/1ec361d00a8178ae8ea0 for possible updates:

: relpath A B
# Calculate relative path from A to B, returns true on success
# Example: ln -s "$(relpath "$A" "$B")" "$B"
relpath()
{
local X Y A
# We can create dangling softlinks
X="$(readlink -m -- "$1")" || return
Y="$(readlink -m -- "$2")" || return
X="${X%/}/"
A=""
while   Y="${Y%/*}"
        [ ".${X#"$Y"/}" = ".$X" ]
do
        A="../$A"
done
X="$A${X#"$Y"/}"
X="${X%/}"
echo "${X:-.}"
}

Notes:

• Care was taken that it is safe against unwanted shell meta character expansion, in case filenames contain * or ?.
• The output is meant to be usable as the first argument to ln -s:
  • relpath / / gives . and not the empty string
  • relpath a a gives a, even if a happens to be a directory
• Most common cases were tested to give reasonable results, too.
• This solution uses string prefix matching, hence readlink is required to canonicalize paths.
• Thanks to readlink -m it works for not yet existing paths, too.

On old systems, where readlink -m is not available, readlink -f fails if the file does not exist. So you probably need some workaround like this (untested!):

readlink_missing()
{
readlink -m -- "$1" && return
readlink -f -- "$1" && return
[ -e . ] && echo "$(readlink_missing "$(dirname "$1")")/$(basename "$1")"
}

This is not really quite correct in case $1 includes . or .. for nonexisting paths (like in /doesnotexist/./a), but it should cover most cases.

(Replace readlink -m -- above by readlink_missing.)

Edit because of the downvote follows

Here is a test, that this function, indeed, is correct:

check()
{
res="$(relpath "$2" "$1")"
[ ".$res" = ".$3" ] && return
printf ':WRONG: %-10q %-10q gives %q\nCORRECT %-10q %-10q gives %q\n' "$1" "$2" "$res" "$@"
}

#     TARGET   SOURCE         RESULT
check "/A/B/C" "/A"           ".."
check "/A/B/C" "/A.x"         "../../A.x"
check "/A/B/C" "/A/B"         "."
check "/A/B/C" "/A/B/C"       "C"
check "/A/B/C" "/A/B/C/D"     "C/D"
check "/A/B/C" "/A/B/C/D/E"   "C/D/E"
check "/A/B/C" "/A/B/D"       "D"
check "/A/B/C" "/A/B/D/E"     "D/E"
check "/A/B/C" "/A/D"         "../D"
check "/A/B/C" "/A/D/E"       "../D/E"
check "/A/B/C" "/D/E/F"       "../../D/E/F"

check "/foo/baz/moo" "/foo/bar" "../bar"

Puzzled? Well, these are the correct results! Even if you think it does not fit the question, here is the proof this is correct:

check "http://example.com/foo/baz/moo" "http://example.com/foo/bar" "../bar"

Without any doubt, ../bar is the exact and only correct relative path of the page bar seen from the page moo. Everything else would be plain wrong.

It is trivial to adopt the output to the question which apparently assumes, that current is a directory:

absolute="/foo/bar"
current="/foo/baz/foo"
relative="../$(relpath "$absolute" "$current")"

This returns exactly, what was asked for.

And before you raise an eyebrow, here is a bit more complex variant of relpath (spot the small difference), which should work for URL-Syntax, too (so a trailing / survives, thanks to some bash-magic):

# Calculate relative PATH to the given DEST from the given BASE
# In the URL case, both URLs must be absolute and have the same Scheme.
# The `SCHEME:` must not be present in the FS either.
# This way this routine works for file paths an
: relpathurl DEST BASE
relpathurl()
{
local X Y A
# We can create dangling softlinks
X="$(readlink -m -- "$1")" || return
Y="$(readlink -m -- "$2")" || return
X="${X%/}/${1#"${1%/}"}"
Y="${Y%/}${2#"${2%/}"}"
A=""
while   Y="${Y%/*}"
        [ ".${X#"$Y"/}" = ".$X" ]
do
        A="../$A"
done
X="$A${X#"$Y"/}"
X="${X%/}"
echo "${X:-.}"
}

And here are the checks just to make clear: It really works as told.

check()
{
res="$(relpathurl "$2" "$1")"
[ ".$res" = ".$3" ] && return
printf ':WRONG: %-10q %-10q gives %q\nCORRECT %-10q %-10q gives %q\n' "$1" "$2" "$res" "$@"
}

#     TARGET   SOURCE         RESULT
check "/A/B/C" "/A"           ".."
check "/A/B/C" "/A.x"         "../../A.x"
check "/A/B/C" "/A/B"         "."
check "/A/B/C" "/A/B/C"       "C"
check "/A/B/C" "/A/B/C/D"     "C/D"
check "/A/B/C" "/A/B/C/D/E"   "C/D/E"
check "/A/B/C" "/A/B/D"       "D"
check "/A/B/C" "/A/B/D/E"     "D/E"
check "/A/B/C" "/A/D"         "../D"
check "/A/B/C" "/A/D/E"       "../D/E"
check "/A/B/C" "/D/E/F"       "../../D/E/F"

check "/foo/baz/moo" "/foo/bar" "../bar"
check "http://example.com/foo/baz/moo" "http://example.com/foo/bar" "../bar"

check "http://example.com/foo/baz/moo/" "http://example.com/foo/bar" "../../bar"
check "http://example.com/foo/baz/moo"  "http://example.com/foo/bar/" "../bar/"
check "http://example.com/foo/baz/moo/"  "http://example.com/foo/bar/" "../../bar/"

And here is how this can be used to give the wanted result from the question:

absolute="/foo/bar"
current="/foo/baz/foo"
relative="$(relpathurl "$absolute" "$current/")"
echo "$relative"

If you find something which does not work, please let me know in the comments below. Thanks.

PS:

Why are the arguments of relpath "reversed" in contrast to all the other answers here?

If you change

Y="$(readlink -m -- "$2")" || return

to

Y="$(readlink -m -- "${2:-"$PWD"}")" || return

then you can leave the 2nd parameter away, such that the BASE is the current directory/URL/whatever. That's only the Unix principle, as usual.

if (a.y - b.y) is less than (a.x - b.x), m is always zero.

so cast it like this.

float m = ((float)(a.y - b.y)) / ((float)(a.x - b.x));

Stuff them into a map (pseudocode)

map[string -> int] $m
foreach($word in $array)
{
    if(!$m.contains($word))
        $m[$word] = 0;

    $m[$word] += 1;
}

DateTime? d=null;
DateTime d2;
bool success = DateTime.TryParse("some date text", out d2);
if (success) d=d2;

(There might be more elegant solutions, but why don't you simply do something as above?)

Yes there is retainAll check out this

Set<Type> intersection = new HashSet<Type>(s1);
intersection.retainAll(s2);

  var stud = (from s1 in entities.Students
            where s1.ID== student.ID
            select s1).SingleOrDefault();

  //Delete it from memory
  entities.DeleteObject(stud);
  //Save to database
  entities.SaveChanges();

I know the perfect answer:

1. double click on The password TextBox.
2. write your textbox name like textbox2.
3. write PasswordChar = '*';.

4. I prefer going to windows character map and find a perfect hide like ?.

   example:TextBox2.PasswordChar = '?';
   

The statement from Microsoft regarding the end of Internet Explorer 11 support mentions that it will continue to receive security updates, compatibility fixes, and technical support until its end of life. The wording of this statement leads me to believe that Microsoft has no plans to continue adding features to Internet Explorer 11, and instead will be focusing on Edge.

If you require ES6 features in Internet Explorer 11, check out a transpiler such as Babel.

If you want multiple lines consider this:

<textarea rows="2"></textarea>

Specify rows as needed.

As I don't plan to support old MS IE versions at all, I've simply replaced all references to browser.msie with false. Not a nice solution, I know, but it works for me.

(Actually, they appeared as !browser.msie, which could be omitted from the conditions.)

The natural question is why not just use grep?! But assuming you can't...

import re
import sys

file = open(sys.argv[2], "r")

for line in file:
     if re.search(sys.argv[1], line):
         print line,

Things to note:

• search instead of match to find anywhere in string
• comma (,) after print removes carriage return (line will have one)
• argv includes python file name, so variables need to start at 1

This doesn't handle multiple arguments (like grep does) or expand wildcards (like the Unix shell would). If you wanted this functionality you could get it using the following:

import re
import sys
import glob

for arg in sys.argv[2:]:
    for file in glob.iglob(arg):
        for line in open(file, 'r'):
            if re.search(sys.argv[1], line):
                print line,

change

public static final String URL = "http://api-Location";

to

public static final String URL = "https://api-Location"

it's happen because i'm using 000webhostapp app

This did the job for me including active main dropdowns and the active childrens (thanks to 422):

$(document).ready(function () {
    var url = window.location;
    // Will only work if string in href matches with location
    $('ul.nav a[href="' + url + '"]').parent().addClass('active');

    // Will also work for relative and absolute hrefs
    $('ul.nav a').filter(function () {
        return this.href == url;
    }).parent().addClass('active').parent().parent().addClass('active');
});

I ended her with the same problem and I could not use the the solution with onEditorAction or onFocusChange and did not want to try the timer. A timer is too dangerous for may taste, because of all the threads and too unpredictable, as you do not know when you code is executed.

The onEditorAction do not catch when the user leave without using a button and if you use it please notice that KeyEvent can be null. The focus is unreliable at both ends the user can get focus and leave without enter any text or selecting the field and the user do not need to leave the last EditText field.

My solution use onFocusChange and a flag set when the user starts editing text and a function to get the text from the last focused view, which I call when need.

I just clear the focus on all my text fields to tricker the leave text view code, The clearFocus code is only executed if the field has focus. I call the function in onSaveInstanceState so I do not have to save the flag (mEditing) as a state of the EditText view and when important buttons is clicked and when the activity is closed.

Be careful with TexWatcher as it is call often I use the condition on focus to not react when the onRestoreInstanceState code entering text. I

final EditText mEditTextView = (EditText) getView();

    mEditTextView.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {

        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {

        }

        @Override
        public void afterTextChanged(Editable s) {
            if (!mEditing && mEditTextView.hasFocus()) {
                mEditing = true;
            }
        }
    });
    mEditTextView.setOnFocusChangeListener(new View.OnFocusChangeListener() {

        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if (!hasFocus && mEditing) {
                mEditing = false;
                ///Do the thing
            }
        }
    });
protected void saveLastOpenField(){
    for (EditText view:getFields()){
            view.clearFocus();
    }
}

A side comment here for those using any of these answers. Juba's answer is great, as it's very selective if your variables are either numberic or character strings. If however, you have a combination (e.g. a1, b1, a2, b2) etc. It will not convert the characters properly.

As @Trenton Hoffman notes,

library(dplyr)
df <- mutate_each(df, funs(toupper))

affects both character and factor classes and works for "mixed variables"; e.g. if your variable contains both a character and a numberic value (e.g. a1) both will be converted to a factor. Overall this isn't too much of a concern, but if you end up wanting match data.frames for example

df3 <- df1[df1$v1 %in% df2$v1,]

where df1 has been has been converted and df2 contains a non-converted data.frame or similar, this may cause some problems. The work around is that you briefly have to run

df2 <- df2 %>% mutate_each(funs(toupper), v1)
#or
df2 <- df2 %>% mutate_each(df2, funs(toupper))
#and then
df3 <- df1[df1$v1 %in% df2$v1,]

If you work with genomic data, this is when knowing this can come in handy.

Based on Agus's function, but I prefer return just the match values:

var bob = "> bob <";
function matchAll(str, regex) {
    var res = [];
    var m;
    if (regex.global) {
        while (m = regex.exec(str)) {
            res.push(m[1]);
        }
    } else {
        if (m = regex.exec(str)) {
            res.push(m[1]);
        }
    }
    return res;
}
var Amatch = matchAll(bob, /(&.*?;)/g);
console.log(Amatch);  // yeilds: [>, <]

Instead of making assumptions about the byte range of non-ASCII characters, as most of the above solutions do, it's slightly better IMO to be explicit about the actual byte range of ASCII characters instead.

So the first solution for instance would become:

grep --color='auto' -P -n '[^\x00-\x7F]' file.xml

(which basically greps for any character outside of the hexadecimal ASCII range: from \x00 up to \x7F)

On Mountain Lion that won't work (due to the lack of PCRE support in BSD grep), but with pcre installed via Homebrew, the following will work just as well:

pcregrep --color='auto' -n '[^\x00-\x7F]' file.xml

Any pros or cons that anyone can think off?

var newData = [1,2,3,4,5,6,7];
var chart = $('#chartjs').highcharts();
chart.series[0].setData(newData, true);

Explanation:
Variable newData contains value that want to update in chart. Variable chart is an object of a chart. setData is a method provided by highchart to update data.

Method setData contains two parameters, in first parameter we need to pass new value as array and second param is Boolean value. If true then chart updates itself and if false then we have to use redraw() method to update chart (i.e chart.redraw();)

You cannot as there is no file input/output in Javascript. See here for a similar question posted.

None of these options show up for me. The way to paste data from Excel is as follows:

• Add an extra column to the left of your spreadsheet data (if you don't have row numbers showing in PL/SQL Developer you may not have to have an extra empty column to the left).

• Copy the rows of data from your spreadsheet including the empty column.

• In PL/SQL Developer, open your table in edit mode. You can right-click the table name in the object browser and select Edit Data or write your own select statement that includes the rowid and click the lock icon. Be sure your columns are ordered the same as in your spreadsheet.

• Here's the part that took me forever to figure out: click on the left side of the first empty row to highlight it. It will not work if you don't have the first empty row highlighted.

• Paste as usual using Ctrl+V or right-click Paste.

I couldn't find this info anywhere when I needed it, so I wanted to be sure to post it.

this is a sample of one of my app how i handle

 //searching for the Edit Text in the view    
    final EditText myEditText =(EditText)view.findViewById(R.id.myEditText);
        myEditText.setOnKeyListener(new View.OnKeyListener() {
            public boolean onKey(View v, int keyCode, KeyEvent event) {
                 if (event.getAction() == KeyEvent.ACTION_DOWN)
                      if ((keyCode == KeyEvent.KEYCODE_DPAD_CENTER) ||
                             (keyCode == KeyEvent.KEYCODE_ENTER)) {
                                //do something
                                //true because you handle the event
                                return true;
                               }
                       return false;
                       }
        });
