I used this code to fix the issue of displaying items in the horizontal list.

new Container(
      height: 20,
      child: Row(
        mainAxisAlignment: MainAxisAlignment.end,
        children: <Widget>[
          ListView.builder(
            scrollDirection: Axis.horizontal,
            shrinkWrap: true,
            itemCount: array.length,
            itemBuilder: (context, index){
              return array[index];
            },
          ),
        ],
      ),
    );

OLD: Create a global instance of _MyHomePageState. Use this instance in _SubState as _myHomePageState.setState

NEW: No need to create global instance. Instead just pass the parent instance to the child widget

CODE UPDATED AS PER FLUTTER 0.8.2:

Just let me know if it works.

Instead of using --no-optional every single time, we can just add it to npm or yarn config.

For Yarn, there is a default no-optional config, so we can just edit that:

yarn config set ignore-optional true

For npm, there is no default config set, so we can create one:

npm config set ignore-optional true

That depends. If said file is publicly available via your HTTP server or servlet container you can simply redirect to via response.sendRedirect().

If it's not, you'll need to manually copy it to response output stream:

OutputStream out = response.getOutputStream();
FileInputStream in = new FileInputStream(my_file);
byte[] buffer = new byte[4096];
int length;
while ((length = in.read(buffer)) > 0){
    out.write(buffer, 0, length);
}
in.close();
out.flush();

You'll need to handle the appropriate exceptions, of course.

1. Turn on usb debugging
2. Turn on Install via USB :-> While turning on it asks for mi account sign in you can get instant otp vis sms service to sign in quickly.
3. Turn off MIUI optimization.

Despite this being against the general SO policy on these matters, this seems to be what the OP genuinely wants:

http://www.google.com/search?btnG=1&pws=0&q=java+executable+wrapper

If you'd like, you could also try creating the appropriate batch or script file containing the single line:

java -jar MyJar.jar

Or in many cases on windows just double clicking the executable jar.

Check this following steps

1. Database.SetInitializer(null); -->in Global.asax.cs

2.

1. your Context class name should match with check it

//create a variable that contain your button
Button button = (Button) findViewById(R.id.button);

    button.setOnClickListener(new OnClickListener(){
        @Override
        //On click function
        public void onClick(View view) {
            //Create the intent to start another activity
            Intent intent = new Intent(view.getContext(), AnotherActivity.class);
            startActivity(intent);
        }
    });

You could also just compile the following program and run it on your machine.

#include <gtk/gtk.h>
#include <glib/gprintf.h>

int main(int argc, char *argv[])
{
    /* Initialize GTK */
    gtk_init (&argc, &argv);

    g_printf("%d.%d.%d\n", gtk_major_version, gtk_minor_version, gtk_micro_version);
    return(0);
}

compile with ( assuming above source file is named version.c):

gcc version.c -o version `pkg-config --cflags --libs gtk+-2.0`

When you run this you will get some output. On my old embedded device I get the following:

[root@n00E04B3730DF n2]# ./version 
2.10.4
[root@n00E04B3730DF n2]#

You can download from terminal or cmd like this:

$sudo apt update 
$sudo apt install android-tools-adb android-tools-fastboot

//check version or test adb is running or not
$adb version

var seconds = 0;
setInterval(function () {
  seconds++;
}, 1000);

There you go, now you have a variable counting seconds elapsed. Since I don't know the context, you'll have to decide whether you want to attach that variable to an object or make it global.

Set interval is simply a function that takes a function as it's first parameter and a number of milliseconds to repeat the function as it's second parameter.

You could also solve this by saving and comparing times.

EDIT: This answer will provide very inconsistent results due to things such as the event loop and the way browsers may choose to pause or delay processing when a page is in a background tab. I strongly recommend using the accepted answer.

If storage class is static or global then during loading, the BSS initialises the variable or memory location(ML) to 0 unless the variable is initially assigned some value. In case of local uninitialized variables the trap representation is assigned to memory location. So if any of your registers containing important info is overwritten by compiler the program may crash.

but some compilers may have mechanism to avoid such a problem.

I was working with nec v850 series when i realised There is trap representation which has bit patterns that represent undefined values for data types except for char. When i took a uninitialized char i got a zero default value due to trap representation. This might be useful for any1 using necv850es

Here is a simple generic C++11 function contains which works for both arrays and containers:

using namespace std;

template<class C, typename T>
bool contains(C&& c, T e) { return find(begin(c), end(c), e) != end(c); };

Simple usage contains(arr, el) is somewhat similar to in keyword semantics in Python.

Here is a complete demo:

#include <algorithm>
#include <array>
#include <string>
#include <vector>
#include <iostream>

template<typename C, typename T>
bool contains(C&& c, T e) { 
    return std::find(std::begin(c), std::end(c), e) != std::end(c);
};

template<typename C, typename T>
void check(C&& c, T e) {
    std::cout << e << (contains(c,e) ? "" : " not") <<  " found\n";
}

int main() {
    int a[] = { 10, 15, 20 };
    std::array<int, 3> b { 10, 10, 10 };
    std::vector<int> v { 10, 20, 30 };
    std::string s { "Hello, Stack Overflow" };
    
    check(a, 10);
    check(b, 15);
    check(v, 20);
    check(s, 'Z');

    return 0;
}

Output:

10 found
15 not found
20 found
Z not found

pip is a command line tool, not Python syntax.

In other words, run the command in your console, not in the Python interpreter:

pip install beautifulsoup4

You may have to use the full path:

C:\Python27\Scripts\pip install beautifulsoup4

or even

C:\Python27\Scripts\pip.exe install beautifulsoup4

Windows will then execute the pip program and that will use Python to install the package.

Another option is to use the Python -m command-line switch to run the pip module, which then operates exactly like the pip command:

python -m pip install beautifulsoup4

or

python.exe -m pip install beautifulsoup4

One advantage is that, we can non-sequentially process XML documents and unmarshal XML data from different sources like InputStream object, a URL, a DOM node...

I ended up going with the following solution:

public class HttpActionResult : IHttpActionResult
{
    private readonly string _message;
    private readonly HttpStatusCode _statusCode;

    public HttpActionResult(HttpStatusCode statusCode, string message)
    {
        _statusCode = statusCode;
        _message = message;
    }

    public Task<HttpResponseMessage> ExecuteAsync(CancellationToken cancellationToken)
    {
        HttpResponseMessage response = new HttpResponseMessage(_statusCode)
        {
            Content = new StringContent(_message)
        };
        return Task.FromResult(response);
    }
}

... which can be used like this:

public IHttpActionResult Get()
{
   return new HttpActionResult(HttpStatusCode.InternalServerError, "error message"); // can use any HTTP status code
}

I'm open to suggestions for improvement. :)

Using Playframework 2.6, the Json library found in the java api can also be used to simply parse the string. The string can either be a json element of json array. Since the returned value is not of importance here we just catch the parse error to determine that the string is a correct json string or not.

    import play.libs.Json;

    public static Boolean isValidJson(String value) {
        try{
            Json.parse(value);
            return true;
        } catch(final Exception e){
            return false;
        }
    }

Solution

1. Create new UNIQUE key that is identical to your current PRIMARY key
2. Add new column id is unsigned integer, auto_increment
3. Create primary key on new id column

Bam, immediate 10x+ insert improvement.

Long term, you will be able to use the ResizeObserver.

new ResizeObserver(callback).observe(element);

Unfortunately it is not currently supported by default in many browsers.

In the mean time, you can use function like the following. Since, the majority of element size changes will come from the window resizing or from changing something in the DOM. You can listen to window resizing with the window's resize event and you can listen to DOM changes using MutationObserver.

Here's an example of a function that will call you back when the size of the provided element changes as a result of either of those events:

var onResize = function(element, callback) {
  if (!onResize.watchedElementData) {
    // First time we are called, create a list of watched elements
    // and hook up the event listeners.
    onResize.watchedElementData = [];

    var checkForChanges = function() {
      onResize.watchedElementData.forEach(function(data) {
        if (data.element.offsetWidth !== data.offsetWidth ||
            data.element.offsetHeight !== data.offsetHeight) {
          data.offsetWidth = data.element.offsetWidth;
          data.offsetHeight = data.element.offsetHeight;
          data.callback();
        }
      });
    };

    // Listen to the window's size changes
    window.addEventListener('resize', checkForChanges);

    // Listen to changes on the elements in the page that affect layout 
    var observer = new MutationObserver(checkForChanges);
    observer.observe(document.body, { 
      attributes: true,
      childList: true,
      characterData: true,
      subtree: true 
    });
  }

  // Save the element we are watching
  onResize.watchedElementData.push({
    element: element,
    offsetWidth: element.offsetWidth,
    offsetHeight: element.offsetHeight,
    callback: callback
  });
};

A solution for:

• Both 32-bit AND 64-bit processes
• System.Diagnostics only (no System.Management)

I used the solution from Russell Gantman and rewritten it as an extension method you can use like this:

var process = Process.GetProcessesByName("explorer").First();
string path = process.GetMainModuleFileName();
// C:\Windows\explorer.exe

With this implementation:

internal static class Extensions {
    [DllImport("Kernel32.dll")]
    private static extern bool QueryFullProcessImageName([In] IntPtr hProcess, [In] uint dwFlags, [Out] StringBuilder lpExeName, [In, Out] ref uint lpdwSize);

    public static string GetMainModuleFileName(this Process process, int buffer = 1024) {
        var fileNameBuilder = new StringBuilder(buffer);
        uint bufferLength = (uint)fileNameBuilder.Capacity + 1;
        return QueryFullProcessImageName(process.Handle, 0, fileNameBuilder, ref bufferLength) ?
            fileNameBuilder.ToString() :
            null;
    }
}

Here is a simple function I created for cleaning any spaces before or after, and multiple spaces within a string. It gracefully handles up to about 108 spaces in a single stretch and as many blocks as there are in the string. You can increase that by factors of 8 by adding additional lines with larger chunks of spaces if you need to. It seems to perform quickly and has not caused any problems in spite of it's generalized use in a large application.

CREATE FUNCTION [dbo].[fnReplaceMultipleSpaces] (@StrVal AS VARCHAR(4000)) 
RETURNS VARCHAR(4000) 
AS 
BEGIN

    SET @StrVal = Ltrim(@StrVal)
    SET @StrVal = Rtrim(@StrVal)

    SET @StrVal = REPLACE(@StrVal, '                ', ' ')  -- 16 spaces
    SET @StrVal = REPLACE(@StrVal, '        ', ' ')  -- 8 spaces
    SET @StrVal = REPLACE(@StrVal, '    ', ' ')  -- 4 spaces
    SET @StrVal = REPLACE(@StrVal, '  ', ' ')  -- 2 spaces
    SET @StrVal = REPLACE(@StrVal, '  ', ' ')  -- 2 spaces (for odd leftovers)

RETURN @StrVal

END

You can do something like this:

jQuery.fn.existsWithValue = function() { 
    return this.length && this.val().length; 
}

if ($(selector).existsWithValue()) {
        // Do something
}

If you want to get the form data directly from Http request, without any model bindings or FormCollection you can use this:

[HttpPost] 
public ActionResult SubmitAction() {

    // This will return an string array of all keys in the form.
    // NOTE: you specify the keys in form by the name attributes e.g:
    // <input name="this is the key" value="some value" type="test" />
    var keys = Request.Form.AllKeys;

    // This will return the value for the keys.
    var value1 = Request.Form.Get(keys[0]);
    var value2 = Request.Form.Get(keys[1]);
}

For Swift 5.0 and iOS 12

extension UIImage {
    func imageResized(to size: CGSize) -> UIImage {
        return UIGraphicsImageRenderer(size: size).image { _ in
            draw(in: CGRect(origin: .zero, size: size))
        }
    }
}

use:

let image = #imageLiteral(resourceName: "ic_search")
cell!.search.image = image.imageResized(to: cell!.search.frame.size)

Since Notepad++ Version 6 you can use this regex in the search and replace dialogue:

^(.*?)$\s+?^(?=.*^\1$)

and replace with nothing. This leaves from all duplicate rows the last occurrence in the file.

No sorting is needed for that and the duplicate rows can be anywhere in the file!

You need to check the options "Regular expression" and ". matches newline":

• ^ matches the start of the line.

• (.*?) matches any characters 0 or more times, but as few as possible (It matches exactly on row, this is needed because of the ". matches newline" option). The matched row is stored, because of the brackets around and accessible using \1

• $ matches the end of the line.

• \s+?^ this part matches all whitespace characters (newlines!) till the start of the next row ==> This removes the newlines after the matched row, so that no empty row is there after the replacement.

• (?=.*^\1$) this is a positive lookahead assertion. This is the important part in this regex, a row is only matched (and removed), when there is exactly the same row following somewhere else in the file.

According to Cliff Click in his 2009 Java One talk A Crash Course in Modern Hardware:

Today, performance is dominated by patterns of memory access. Cache misses dominate – memory is the new disk. [Slide 65]

You can get his full slides here.

Cliff gives an example (finishing on Slide 30) showing that even with the CPU doing register-renaming, branch prediction, and speculative execution, it's only able to start 7 operations in 4 clock cycles before having to block due to two cache misses which take 300 clock cycles to return.

So he says to speed up your program you shouldn't be looking at this sort of minor issue, but on larger ones such as whether you're making unnecessary data format conversions, such as converting "SOAP ? XML ? DOM ? SQL ? …" which "passes all the data through the cache".

My problem was that I had @WebServlet("/route") and the same servlet declared in web.xml

To define "soft real-time," it is easiest to compare it with "hard real-time." Below we will see that the term "firm real-time" constitutes a misunderstanding about "soft real-time."

Speaking casually, most people implicitly have an informal mental model that considers information or an event as being "real-time"

• if, or to the extent that, it is manifest to them with a delay (latency) that can be related to its perceived currency

• i.e., in a time frame that the information or event has acceptably satisfactory value to them.

There are numerous different ad hoc definitions of "hard real-time," but in that mental model, hard real-time is represented by the "if" term. Specifically, assuming that real-time actions (such as tasks) have completion deadlines, acceptably satisfactory value of the event that all tasks complete is limited to the special case that all tasks meet their deadlines.

Hard real-time systems make the very strong assumptions that everything about the application and system and environment is static and known a' priori—e.g., which tasks, that they are periodic, their arrival times, their periods, their deadlines, that they won’t have resource conflicts, and overall the time evolution of the system. In an aircraft flight control system or automotive braking system and many other cases those assumptions can usually be satisfied so that all the deadlines will be met.

This mental model is deliberately and very usefully general enough to encompass both hard and soft real-time--soft is accommodated by the "to the extent that" phrase. For example, suppose that the task completions event has suboptimal but acceptable value if

• no more than 10% of the tasks miss their deadlines
• or no task is more than 20% tardy
• or the average tardiness of all tasks is no more than 15%
• or the maximum tardiness among all tasks is less than 10%

These are all common examples of soft real-time cases in a great many applications.

Consider the single-task application of picking your child up after school. That probably does not have an actual deadline, instead there is some value to you and your child based on when that event takes place. Too early wastes resources (such as your time) and too late has some negative value because your child might be left alone and potentially in harm's way (or at least inconvenienced).

Unlike the static hard real-time special case, soft real-time makes only the minimum necessary application-specific assumptions about the tasks and system, and uncertainties are expected. To pick up your child, you have to drive to the school, and the time to do that is dynamic depending on weather, traffic conditions, etc. You might be tempted to over-provision your system (i.e., allow what you hope is the worst case driving time) but again this is wasting resources (your time, and occupying the family vehicle, possibly denying use by other family members).

That example may not seem to be costly in terms of wasted resources, but consider other examples. All military combat systems are soft real-time. For example, consider performing an aircraft attack on a hostile ground vehicle using a missile guided with updates to it as the target maneuvers. The maximum satisfaction for completing the course update tasks is achieved by a direct destructive strike on the target. But an attempt to over-provision resources to make certain of this outcome is usually far too expensive and may even be impossible. In this case, you may be less but sufficiently satisfied if the missile strikes close enough to the target to disable it.

Obviously combat scenarios have a great many possible dynamic uncertainties that must be accommodated by the resource management. Soft real-time systems are also very common in many civilian systems, such as industrial automation, although obviously military ones are the most dangerous and urgent ones to achieve acceptably satisfactory value in.

The keystone of real-time systems is "predictability." The hard real-time case is interested in only one special case of predictability--i.e., that the tasks will all meet their deadlines and the maximum possible value will be achieved by that event. That special case is named "deterministic."

There is a spectrum of predictability. Deterministic (determinism) is one end-point (maximum predictability) on the predictability spectrum; the other end-point is minimum predictability (maximum non-determinism). The spectrum's metric and end-points have to be interpreted in terms of a chosen predictability model; everything between those two end-points is degrees of unpredictability (= degrees of non-determinism).

Most real-time systems (namely, soft ones) have non-deterministic predictability, for example, of the tasks' completions times and hence the values gained from those events.

In general (in theory), predictability, and hence acceptably satisfactory value, can be made as close to the deterministic end-point as necessary--but at a price which may be physically impossible or excessively expensive (as in combat or perhaps even in picking up your child from school).

Soft real-time requires an application-specific choice of a probability model (not the common frequentist model) and hence predictability model for reasoning about event latencies and resulting values.

Referring back to the above list of events that provide acceptable value, now we can add non-deterministic cases, such as

• the probability that no task will miss its deadline by more than 5% is greater than 0.87. (Note the number of scheduling criteria expressed in there.)

In a missile defense application, given the fact that in combat the offense always has the advantage over the defense, which of these two real-time computing scenarios would you prefer:

• because the perfect destruction of all the hostile missiles is very unlikely or impossible, assign your defensive resources to maximize the probability that as many of the most threatening (e.g., based on their targets) hostile missiles will be successfully intercepted (close interception counts because it can move the hostile missile off-course);

• complain that this is not a real-time computing problem because it is dynamic instead of static, and traditional real-time concepts and techniques do not apply, and it sounds more difficult than static hard real-time, so you are not interested in it.

Despite the various misunderstandings about soft real-time in the real-time computing community, soft real-time is very general and powerful, albeit potentially complex compared with hard real-time. Soft real-time systems as summarized here have a lengthy successful history of use outside the real-time computing community.

To directly answer the OP question:

A hard real-time system can provide deterministic guarantees—most commonly that all tasks will meet their deadlines, interrupt or system call response time will always be less than x, etc.—IF AND ONLY IF very strong assumptions are made and are correct that everything that matters is static and known a' priori (in general, such guarantees for hard real-time systems are an open research problem except for rather simple cases)

A soft real-time system does not make deterministic guarantees, it is intended to provide the best possible analytically specified and accomplished probabilistic timeliness and predictability of timeliness that are feasible under the current dynamic circumstances, according to application-specific criteria.

Obviously hard real-time is a simple special case of soft real-time. Obviously soft real-time's analytical non-deterministic assurances can be very complex to provide, but are mandatory in the most common real-time cases (including the most dangerous safety-critical ones such as combat) since most real-time cases are dynamic not static.

"Firm real-time" is an ill-defined special case of "soft real-time." There is no need for this term if the term "soft real-time" is understood and used properly.

I have a more detailed much more precise discussion of real-time, hard real-time, soft real-time, predictability, determinism, and related topics on my web site real-time.org.

If DB is SQL Server then

Django forms module uses __call__ method nicely to implement a consistent API for form validation. You can write your own validator for a form in Django as a function.

def custom_validator(value):
    #your validation logic

Django has some default built-in validators such as email validators, url validators etc., which broadly fall under the umbrella of RegEx validators. To implement these cleanly, Django resorts to callable classes (instead of functions). It implements default Regex Validation logic in a RegexValidator and then extends these classes for other validations.

class RegexValidator(object):
    def __call__(self, value):
        # validation logic

class URLValidator(RegexValidator):
    def __call__(self, value):
        super(URLValidator, self).__call__(value)
        #additional logic

class EmailValidator(RegexValidator):
    # some logic

Now both your custom function and built-in EmailValidator can be called with the same syntax.

for v in [custom_validator, EmailValidator()]:
    v(value) # <-----

As you can see, this implementation in Django is similar to what others have explained in their answers below. Can this be implemented in any other way? You could, but IMHO it will not be as readable or as easily extensible for a big framework like Django.

Fiddle

git log -p will generate the a patch (the diff) for every commit selected. For a single file, use git log --follow -p $file.

If you're looking for a particular change, use git bisect to find the change in log(n) views by splitting the number of commits in half until you find where what you're looking for changed.

Also consider looking back in history using git blame to follow changes to the line in question if you know what that is. This command shows the most recent revision to affect a certain line. You may have to go back a few versions to find the first change where something was introduced if somebody has tweaked it over time, but that could give you a good start.

Finally, gitk as a GUI does show me the patch immediately for any commit I click on.

Example :

Linked to, but not explicitly mentioned here, is exactly when __all__ is used. It is a list of strings defining what symbols in a module will be exported when from <module> import * is used on the module.

For example, the following code in a foo.py explicitly exports the symbols bar and baz:

__all__ = ['bar', 'baz']

waz = 5
bar = 10
def baz(): return 'baz'

These symbols can then be imported like so:

from foo import *

print(bar)
print(baz)

# The following will trigger an exception, as "waz" is not exported by the module
print(waz)

If the __all__ above is commented out, this code will then execute to completion, as the default behaviour of import * is to import all symbols that do not begin with an underscore, from the given namespace.

Reference: https://docs.python.org/tutorial/modules.html#importing-from-a-package

NOTE: __all__ affects the from <module> import * behavior only. Members that are not mentioned in __all__ are still accessible from outside the module and can be imported with from <module> import <member>.

Works and without loops

This method doesn't use any loops and is actually quite simple. It expands the date range to full weeks since we know that each week has 5 business days. It then uses a lookup table to find the number of business days to subtract from the start and end to get the right result. I've expanded out the calculation to help show what's going on, but the whole thing could be condensed into a single line if needed.

Anyway, this works for me and so I thought I'd post it here in case it might help others. Happy coding.

Calculation

• t : Total number of days between dates (1 if min = max)
• a + b : Extra days needed to expand total to full weeks
• k : 1.4 is number of weekdays per week, i.e., (t / 7) * 5
• c : Number of weekdays to subtract from the total
• m : A lookup table used to find the value of "c" for each day of the week

Culture

Code assumes a Monday to Friday work week. For other cultures, such as Sunday to Thursday, you'll need to offset the dates prior to calculation.

Method

public int Weekdays(DateTime min, DateTime max) 
{       
        if (min.Date > max.Date) throw new Exception("Invalid date span");
        var t = (max.AddDays(1).Date - min.Date).TotalDays;
        var a = (int) min.DayOfWeek;
        var b = 6 - (int) max.DayOfWeek;
        var k = 1.4;
        var m = new int[]{0, 0, 1, 2, 3, 4, 5}; 
        var c = m[a] + m[b];
        return (int)((t + a + b) / k) - c;
}

another language meta tag is og:locale and you can define og:locale meta tag for social media

<meta property="og:locale" content="en" />

In C, the type of a character constant like 'a' is actually an int, with size of 4 (or some other implementation-dependent value). In C++, the type is char, with size of 1. This is one of many small differences between the two languages.

I think this will work perfectly. I used the same:

For Android Studio:

1. Click on Build > Generate Signed APK.
2. You will get a message box, just click OK.
3. Now there will be another window just copy Key Store Path.
4. Now open a command prompt and go to C:\Program Files\Java\jdk1.6.0_39\bin> (or any installed jdk version).
5. Type keytool -list -v -keystore and then paste your Key Store Path (Eg. C:\Program Files\Java\jdk1.6.0_39\bin>keytool -list -v -keystore "E:\My Projects \Android\android studio\signed apks\Hello World\HelloWorld.jks").
6. Now it will Ask Key Store Password, provide yours and press Enter to get your SHA1 and MD5 Certificate keys.

For MS SQL 2016, passing ints into the in, it looks like it can handle close to 38,000 records.

You can use ViewChild

<child-tag #varName></child-tag>

@ViewChild('varName') someElement;

ngAfterViewInit() {
  someElement...
}

where varName is a template variable added to the element. Alternatively, you can query by component or directive type.

There are alternatives like ViewChildren, ContentChild, ContentChildren.

@ViewChildren can also be used in the constructor.

constructor(@ViewChildren('var1,var2,var3') childQuery:QueryList)

The advantage is that the result is available earlier.

See also http://www.bennadel.com/blog/3041-constructor-vs-property-querylist-injection-in-angular-2-beta-8.htm for some advantages/disadvantages of using the constructor or a field.

Note: @Query() is the deprecated predecessor of @ContentChildren()

You can use google map Obtaining User Location here!

After obtaining your location(longitude and latitude), you can use google place api

This code can help you get your location easily but not the best way.

locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
Criteria criteria = new Criteria();
String bestProvider = locationManager.getBestProvider(criteria, true);
Location location = locationManager.getLastKnownLocation(bestProvider);  

I am using jQuery and surprisingly this seems to load as I just tested and loaded a heavy page and I didn't get the alert for a few seconds until I saw the iframe load:

$('#the_iframe').load(function(){
    alert('loaded!');
});

So if you don't want to use jQuery take a look at their source code and see if this function behaves differently with iframe DOM elements, I will look at it myself later as I am interested and post here. Also I only tested in the latest chrome.

When one has to scroll down a gridview to select a row, MaintainScrollPositionOnPostBack="true" will make it continue to show that row after one has selected it.

Search some samples on the Internet.

The client has a pre-seeded store of SSL certificate authorities' public keys. There must be a chain of trust from the certificate for the server up through intermediate authorities up to one of the so-called "root" certificates in order for the server to be trusted.

You can examine and/or alter the list of trusted authorities. Often you do this to add a certificate for a local authority that you know you trust - like the company you work for or the school you attend or what not.

The pre-seeded list can vary depending on which client you use. The big SSL certificate vendors insure that their root certs are in all the major browsers ($$$).

Monkey-in-the-middle attacks are "impossible" unless the attacker has the private key of a trusted root certificate. Since the corresponding certificates are widely deployed, the exposure of such a private key would have serious implications for the security of eCommerce generally. Because of that, those private keys are very, very closely guarded.

Sure, use the .format method. E.g.,

print('{:10s} {:3d}  {:7.2f}'.format('xxx', 123, 98))
print('{:10s} {:3d}  {:7.2f}'.format('yyyy', 3, 1.0))
print('{:10s} {:3d}  {:7.2f}'.format('zz', 42, 123.34))

will print

xxx        123    98.00
yyyy         3     1.00
zz          42   123.34

You can adjust the field sizes as desired. Note that .format works independently of print to format a string. I just used print to display the strings. Brief explanation:

10s format a string with 10 spaces, left justified by default

3d format an integer reserving 3 spaces, right justified by default

7.2f format a float, reserving 7 spaces, 2 after the decimal point, right justfied by default.

There are many additional options to position/format strings (padding, left/right justify etc), String Formatting Operations will provide more information.

Update for f-string mode. E.g.,

text, number, other_number = 'xxx', 123, 98
print(f'{text:10} {number:3d}  {other_number:7.2f}')

For right alignment

print(f'{text:>10} {number:3d}  {other_number:7.2f}')

I always prefer to use the example mentioned in Konva JS: Image Events to load images.

1. You need to have a list of image URLs as object or array, for example:

   var sources = { lion: '/assets/lion.png', monkey: '/assets/monkey.png' };

2. Define the Function definition, where it receives list of image URLs and a callback function in its arguments list, so when it finishes loading image you can start excution on your web page:

    function loadImages(sources, callback) {_x000D_
                var images = {};_x000D_
                var loadedImages = 0;_x000D_
                var numImages = 0;_x000D_
                for (var src in sources) {_x000D_
                    numImages++;_x000D_
                }_x000D_
                for (var src in sources) {_x000D_
                    images[src] = new Image();_x000D_
                    images[src].onload = function () {_x000D_
                        if (++loadedImages >= numImages) {_x000D_
                            callback(images);_x000D_
                        }_x000D_
                    };_x000D_
                    images[src].src = sources[src];_x000D_
                }_x000D_
            }

3. Lastly, you need to call the function. You can call it for example from jQuery's Document Ready

$(document).ready(function (){ loadImages(sources, buildStage); });

You can use box-shadow to create an outline on one side. Like outline, box-shadow does not change the size of the box model.

This puts a line on top:

box-shadow: 0 -1px 0 #000;

I made a jsFiddle where you can check it out in action.

INSET

For an inset border, use the inset keyword. This puts an inset line on top:

box-shadow: 0 1px 0 #000 inset;

Multiple lines can be added using comma-separated statements. This puts an inset line on the top and the left:

box-shadow: 0 1px 0 #000 inset,
            1px 0 0 #000 inset;

For more details on how box-shadow works, check out the MDN page.

Add the below to the build.gradle project module:

    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.3'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

There can be 2 issues :=

1. Your are trying the command in machine that does not support apt-get command
because apt-get is suitable for Linux based Ubuntu machines; for MAC, try
apt-get equivalent such as Brew

2. The other issue can be that your installation was not completed properly So

The short answer:

Re-install Ubuntu from a Live CD or USB.

The long version:

The long version would be a waste of your time: your system will never
be clean, but if you insist you could try:

==> Copying everything (missing) except for the /home folder from the Live
CD/USB to your HDD.

OR

==> Do a re-install/repair over the broken system again with the Live
CD / USB stick.

OR

==> Download the deb file for apt-get and install as explained on above posts.
I would definitely go for a fresh new install as there are so many things to
do and so little time.

Right click your project in eclipse, build path -> add external jars.

They are returning false because you are testing for object identity rather than value equality. This returns false because your arrays are actually different objects in memory.

If you want to test for value equality should use the handy comparison functions in java.util.Arrays

e.g.

import java.util.Arrays;

'''''

Arrays.equals(a,b);

If your properties file path and your java class path are same then you should this.

For example:

src/myPackage/MyClass.java

src/myPackage/MyFile.properties

Properties prop = new Properties();
InputStream stream = MyClass.class.getResourceAsStream("MyFile.properties");
prop.load(stream);

I made myself a custom jquery function:

Html

<tr data-href="site.com/whatever">

jQuery

$('tr[data-href]').on("click", function() {
    document.location = $(this).data('href');
});

Easy and perfect for me. Hopefully it helps you.

(I know OP want CSS and HTML only, but consider jQuery)

Edit

Agreed with Matt Kantor using data attr. Edited answer above

No - if you want to convert ALL elements of a list, you'll have to touch ALL elements of that list one way or another.

You can specify / write the iteration in different ways (foreach()......, or .ConvertAll() or whatever), but in the end, one way or another, some code is going to iterate over each and every element and convert it.

Marc

Try in yourbatch

set "batchisin=%~dp0"

which should set the variable to your batch's location.

If I need only to highlight the first word as a command, I often use properties:

```properties
npm run build
```  

I obtain something like:

npm run build

The query execution happens on all get methods like

$this->db->get('table_name');
$this->db->get_where('table_name',$array);

While last_query contains the last query which was run

$this->db->last_query();

If you want to get query string without execution you will have to do this. Go to system/database/DB_active_rec.php Remove public or protected keyword from these functions

public function _compile_select($select_override = FALSE)
public function _reset_select()

Now you can write query and get it in a variable

$this->db->select('trans_id');
$this->db->from('myTable');
$this->db->where('code','B');
$subQuery = $this->db->_compile_select();

Now reset query so if you want to write another query the object will be cleared.

$this->db->_reset_select();

And the thing is done. Cheers!!! Note : While using this way you must use

$this->db->from('myTable')

instead of

$this->db->get('myTable')

which runs the query.

Take a look at this example

How about:

df['new_col'] = range(1, len(df) + 1)

Alternatively if you want the index to be the ranks and store the original index as a column:

df = df.reset_index()

You can do:

SELECT column1, column2, column4 FROM table WHERE whatever

without getting column3, though perhaps you were looking for a more general solution?

Say you have a class called MyFancyObject like this one below:

class MyFancyObject
{
 public int A { get;set;}
}

It lets you turn:

String ClassName = "MyFancyObject";

Into

MyFancyObject obj;

Using

obj = (MyFancyObject)Activator.CreateInstance("MyAssembly", ClassName))

and can then do stuff like:

obj.A = 100;

That's its purpose. It also has many other overloads such as providing a Type instead of the class name in a string. Why you would have a problem like that is a different story. Here's some people who needed it:

• Createinstance() - Am I doing this right?
• C# Using Activator.CreateInstance
• Creating an object without knowing the class name at design time

Use this line simply inside your head with

       window.location.reload(true);

It will load your current page or view.

The stupid simple answer

Connect and Express are web servers for nodejs. Unlike Apache and IIS, they can both use the same modules, referred to as "middleware".

if(button.clicked==true) {
    console.log("Button Clicked");
} ==> // This Code Doesn't Work Properly So Please Use Below One // 


function check() { 
    console.log("Button Clicked");
}; // This Code Works Fine // 

var button= document.querySelector("button"); // Accessing The Button // 
button.addEventListener("click", check); // Adding event to call function when clicked // 

Below code worked for me:

string _stDate = Convert.ToDateTime(DateTime.Today.AddMonths(-12)).ToString("MM/dd/yyyy");
String format ="MM/dd/yyyy";
IFormatProvider culture = new System.Globalization.CultureInfo("fr-FR", true);
DateTime _Startdate = DateTime.ParseExact(_stDate, format, culture);

When trying the accepted answer, I was getting an installation error: A failure was detected for a previous installation, patch, or repair blah, blah, blah...

To fix this, in my registry, I changed all DWORD values to 1 in the following Keys: (As always be careful modifying the registry and create a backup of the key before changing anything)

a reply to @DarinDimitrov for a case where i have used foreach in a razor view.

<li><label for="category">Category</label>
        <select id="category">
            <option value="0">All</option>
            @foreach(Category c in Model.Categories)
            {
                <option title="@c.Description" value="@c.CategoryID">@c.Name</option>
            }
        </select>

In mysqli_query(first parameter should be connection,your sql statement) so

$connetion_name=mysqli_connect("localhost","root","","web_table") or die(mysqli_error());
mysqli_query($connection_name,'INSERT INTO web_formitem (ID, formID, caption, key, sortorder, type, enabled, mandatory, data) VALUES (105, 7, Tip izdelka (6), producttype_6, 42, 5, 1, 0, 0)');

but best practice is

$connetion_name=mysqli_connect("localhost","root","","web_table") or die(mysqli_error());
$sql_statement="INSERT INTO web_formitem (ID, formID, caption, key, sortorder, type, enabled, mandatory, data) VALUES (105, 7, Tip izdelka (6), producttype_6, 42, 5, 1, 0, 0)";
mysqli_query($connection_name,$sql_statement);

Is there any good example to give the difference between a 'struct' and a 'union'?

An imaginary communications protocol

struct packetheader {
   int sourceaddress;
   int destaddress;
   int messagetype;
   union request {
       char fourcc[4];
       int requestnumber;
   };
};

In this imaginary protocol, it has been sepecified that, based on the "message type", the following location in the header will either be a request number, or a four character code, but not both. In short, unions allow for the same storage location to represent more than one data type, where it is guaranteed that you will only want to store one of the types of data at any one time.

Unions are largely a low-level detail based in C's heritage as a system programming language, where "overlapping" storage locations are sometimes used in this way. You can sometimes use unions to save memory where you have a data structure where only one of several types will be saved at one time.

In general, the OS doesn't care or know about structs and unions -- they are both simply blocks of memory to it. A struct is a block of memory that stores several data objects, where those objects don't overlap. A union is a block of memory that stores several data objects, but has only storage for the largest of these, and thus can only store one of the data objects at any one time.

Convert from String to byte[]:

String s = "some text here";
byte[] b = s.getBytes(StandardCharsets.UTF_8);

Convert from byte[] to String:

byte[] b = {(byte) 99, (byte)97, (byte)116};
String s = new String(b, StandardCharsets.US_ASCII);

You should, of course, use the correct encoding name. My examples used US-ASCII and UTF-8, the two most common encodings.

That will only work for small numbers and I'm guessing it's also implementation-dependent. Python uses the same object instance for small numbers (iirc <256), but this changes for bigger numbers.

>>> a = 2104214124
>>> b = 2104214124
>>> a == b
True
>>> a is b
False

So you should always use == to compare numbers.

Heres some code in c to convert rgb to grayscale. The real weighting used for rgb to grayscale conversion is 0.3R+0.6G+0.11B. these weights arent absolutely critical so you can play with them. I have made them 0.25R+ 0.5G+0.25B. It produces a slightly darker image.

NOTE: The following code assumes xRGB 32bit pixel format

unsigned int *pntrBWImage=(unsigned int*)..data pointer..;  //assumes 4*width*height bytes with 32 bits i.e. 4 bytes per pixel
unsigned int fourBytes;
        unsigned char r,g,b;
        for (int index=0;index<width*height;index++)
        {
            fourBytes=pntrBWImage[index];//caches 4 bytes at a time
            r=(fourBytes>>16);
            g=(fourBytes>>8);
            b=fourBytes;

            I_Out[index] = (r >>2)+ (g>>1) + (b>>2); //This runs in 0.00065s on my pc and produces slightly darker results
            //I_Out[index]=((unsigned int)(r+g+b))/3;     //This runs in 0.0011s on my pc and produces a pure average
        }

Try change update="insTable:display" to update="display". I believe you cannot prefix the id with the form ID like that.

I had a similar problem when I had to create a dictionary that contained the elements of an array and their count. The answer is relevant because, I flatten a list of lists, get the elements I need and then do a group and count. I used Python's map function to produce a tuple of element and it's count and groupby over the array. Note that the groupby takes the array element itself as the keyfunc. As a relatively new Python coder, I find it to me more easier to comprehend, while being Pythonic as well.

Before I discuss the code, here is a sample of data I had to flatten first:

{ "_id" : ObjectId("4fe3a90783157d765d000011"), "status" : [ "opencalais" ],
  "content_length" : 688, "open_calais_extract" : { "entities" : [
  {"type" :"Person","name" : "Iman Samdura","rel_score" : 0.223 }, 
  {"type" : "Company",  "name" : "Associated Press",    "rel_score" : 0.321 },          
  {"type" : "Country",  "name" : "Indonesia",   "rel_score" : 0.321 }, ... ]},
  "title" : "Indonesia Police Arrest Bali Bomb Planner", "time" : "06:42  ET",         
  "filename" : "021121bn.01", "month" : "November", "utctime" : 1037836800,
  "date" : "November 21, 2002", "news_type" : "bn", "day" : "21" }

It is a query result from Mongo. The code below flattens a collection of such lists.

def flatten_list(items):
  return sorted([entity['name'] for entity in [entities for sublist in  
   [item['open_calais_extract']['entities'] for item in items] 
   for entities in sublist])

First, I would extract all the "entities" collection, and then for each entities collection, iterate over the dictionary and extract the name attribute.

"FirstLine" + "<br/>" "SecondLine"

With hints from @ChristopheD

def line_split(N, K=1):
    length = len(N)
    return [N[i*length/K:(i+1)*length/K] for i in range(K)]

A = [0,1,2,3,4,5,6,7,8,9]
print line_split(A,1)
print line_split(A,2)

This is quite frustrating, but it's a containment issue (the .svn folders keep track also of ignored files). Any item that needs to be ignored is to be added to the ignore list of the immediate parent folder.

So, I had a new sub-folder with a new file in it and wanted to ignore that file but I couldn't do it because the option was grayed out. I solved it by committing the new folder first, which I wanted to (it was a cache folder), and then adding that file to the ignore list (of the newly added folder ;-), having the chance to add a pattern instead of a single file.

The Python documentation provides the perfect solution for this which uses the built-in function dir.

You can just use dir(module_name) and then it will return a list of the functions within that module.

For example, dir(time) will return

['_STRUCT_TM_ITEMS', '__doc__', '__loader__', '__name__', '__package__', '__spec__', 'altzone', 'asctime', 'ctime', 'daylight', 'get_clock_info', 'gmtime', 'localtime', 'mktime', 'monotonic', 'monotonic_ns', 'perf_counter', 'perf_counter_ns', 'process_time', 'process_time_ns', 'sleep', 'strftime', 'strptime', 'struct_time', 'time', 'time_ns', 'timezone', 'tzname', 'tzset']

which is the list of functions the 'time' module contains.

This is what LINQ needs

public static IEnumerable<T> Except<T, TKey>(this IEnumerable<T> items, IEnumerable<T> other, Func<T, TKey> getKey) 
{
    return from item in items
            join otherItem in other on getKey(item)
            equals getKey(otherItem) into tempItems
            from temp in tempItems.DefaultIfEmpty()
            where ReferenceEquals(null, temp) || temp.Equals(default(T))
            select item; 
}

In your Info.plist, Right click in the properties table, click Add Row, add key name App Uses Non-Exempt Encryption with Type Boolean and set value NO.

Make sure that...

• There's an = sign before the formula
• There's no white space before the = sign
• There are no quotes around the formula (must be =A1, instead of "=A1")
• You're not in formula view (hit Ctrl + ` to switch between modes)
• The cell format is set to General instead of Text
• If simply changing the format doesn't work, hit F2, Enter
• Undoing actions (CTRL+Z) back until the value shows again and then simply redoing all those actions with CTRL-Y also worked for some users

A compromised solution is to fake bold with text-shadow, e.g:

text-shadow: 0 0 0.01px black;

For better comparison I created these examples:

a, li {_x000D_
  color: black;_x000D_

Passing to text-shadow really low value for blur-radius will make the blurring effect not so apparent.

In general the more your repeat text-shadow the bolder your text will get but in the same time loosing original shape of the letters.

I should warn you that setting the blur-radius to fractions is not going to render the same in all browsers! Safari for example need bigger values to render it the same way Chrome will do.

In my scenario, there was no process blocking the database under sp_who2. However, we discovered because the database is much larger than our other databases that pending processes were still running which is why the database under the availability group still displayed as red/offline after we tried to 'resume data'by right clicking the paused database.

To check if you still have processes running just execute this command: select percent complete from sys.dm_exec_requests where percent_complete > 0

Through the Javascript SDK (v2.12 - April, 2017) you can get the details of the picture request this way:

FB.api("/" + uid + "/picture?redirect=0", function (response) {
  console.log(response);

  // prints the following:
  //data: {
  //  height: 50
  //  is_silhouette: false
  //  url: "https://lookaside.facebook.com/platform/profilepic/?asid=…&height=50&width=50&ext=…&hash…"
  //  width: 50
  //}

  if (response && !response.error) {
    // change the src attribute of img elements
    [...document.getElementsByClassName('fb-user-img')].forEach(
      i => i.src = response.data.url
    );

    // OR redirect to the URL above
    location.assign(response.data.url);
  }
});

For getting the JSON response the parameter redirect with 0 (zero) as value is important since the request redirects to the image by default. You may still add other parameters in the same URL. Examples:

• "/" + uid + "/picture?redirect=0&width=100&height=100": a 100x100 image will be returned;
• "/" + uid + "/picture?redirect=0&type=large": a 200x200 image is returned. Other possible type values include: small, normal, album, and square.

try Prefix + &

if you have

bind q killp

in your .tmux.conf, you can press Prefix + q to kill the window too, only if there is only one panel in that window.

if you have multiple panes and want to kill the whole window at once use killw instead of killp in your config.

the default of Prefix above is Ctrl+b, so to terminate window by default you can use Ctrl+b &

Short circuit here means that the second condition won't be evaluated.

If ( A && B ) will result in short circuit if A is False.

If ( A && B ) will not result in short Circuit if A is True.

If ( A || B ) will result in short circuit if A is True.

If ( A || B ) will not result in short circuit if A is False.

In my case, I needed to replace this:

@Html.ActionLink("Return license", "Licenses_Revoke", "Licenses", new { id = userLicense.Id }, null)

With this:

<a href="#" onclick="returnLicense(event)">Return license</a>

<script type="text/javascript">
    function returnLicense(e) {
        e.preventDefault();

        $.post('@Url.Action("Licenses_Revoke", "Licenses", new { id = Model.Customer.AspNetUser.UserLicenses.First().Id })', getAntiForgery())
            .done(function (res) {
                window.location.reload();
            });
    }
</script>

Even if I don't understand why. Suggestions are welcome!

It will be faster because it doesnt have to wait for locks

There is no JavaScript function to achieve this. However, you could set a boolean value to true when you add the listener, and false when you remove it. Then check against this boolean before potentially adding a duplicate event listener.

I had the same issue - without Pageable method works fine.
When added as method parameter - doesn't work.

After playing with DB console and native query support came up to decision that method works like it should. However, only for upper case letters.
Logic of my application was that all names of entity starts from upper case letters.

Playing a little bit with it. And discover that IgnoreCase at method name do the "magic" and here is working solution:

public interface EmployeeRepository 
                            extends PagingAndSortingRepository<Employee, Integer> {

    Page<Employee> findAllByNameIgnoreCaseStartsWith(String name, Pageable pageable);

}

Where entity looks like:

@Data
@Entity
@Table(name = "tblEmployees")
public class Employee {

    @Id
    @Column(name = "empID")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Integer id;

    @NotEmpty
    @Size(min = 2, max = 20)
    @Column(name = "empName", length = 25)
    private String name;

    @Column(name = "empActive")
    private Boolean active;

    @ManyToOne
    @JoinColumn(name = "emp_dpID")
    private Department department;
}

Description:

there are 3 steps to run PHP code inside post or page.

1. In functions.php file (in your theme) add new function

2. In functions.php file (in your theme) register new shortcode which call your function:

add_shortcode( 'SHORCODE_NAME', 'FUNCTION_NAME' );

3. use your new shortcode

Example #1: just display text.

In functions:

function simple_function_1() {
    return "Hello World!";
}

add_shortcode( 'own_shortcode1', 'simple_function_1' );

In post/page:

[own_shortcode1]

Effect:

Hello World!

Example #2: use for loop.

In functions:

function simple_function_2() {
    $output = "";
    
    for ($number = 1; $number < 10; $number++) {    
        // Append numbers to the string
        $output .= "$number<br>";
    } 
    
    return "$output";
}

add_shortcode( 'own_shortcode2', 'simple_function_2' );

In post/page:

[own_shortcode2]

Effect:

1
2
3
4
5
6
7
8
9

Example #3: use shortcode with arguments

In functions:

function simple_function_3($name) {
    return "Hello $name";
}

add_shortcode( 'own_shortcode3', 'simple_function_3' );

In post/page:

[own_shortcode3 name="John"]

Effect:

Hello John

Example #3 - without passing arguments

In post/page:

[own_shortcode3]

Effect:

Hello 

Just a note for whoever is trying to add an Objective-C library to Swift: You should add -ObjC in Build Settings -> Linking -> Other Linker Flags.

This error appear because the compiler could not found "my-upload-key.keystore" file in your project

After you have generated the file you need to paste it into project's andorid/app folder

this worked for me!

This error occur when the list in adapter clear when user scrolling which make position of item holder changing, lost ref between list and item on ui, error happen in next "notifyDataSetChanged" request.

Fix:

Review your update list method. If you do something like

mainList.clear();
...
mainList.add() or mainList.addAll()
...
notifyDataSetChanged();

===> Error occur

How to fix. Create new list object for buffer processing and assign again to main list after that

List res = new ArrayList();
…..
res.add();  //add item or modify list
….
mainList = res;
notifyDataSetChanged();

Thanks to Nhan Cao for this great help :)

Believe me, no one wants your source as much as you may think they do. When you decided to develop web pages, you became an open source developer.

It's not possible to disable viewing a pages source. You can attempt to circumvent unknowledgeable users from seeing the source, but it won't stop anyone who understands how to use menu's or shortcut keys. Your best bet is to develop your site in a manner that will not be compromised by someone seeing your source. If you're attempting to hide it for any other reason than to protect your intellectual property, then you're doing something wrong.

If you are using custom filter, you might want to hide search box but still want to enable the filter function, so bFilter: false is not the way. Use dom: 'lrtp' instead, default is 'lfrtip'. Documentation: https://datatables.net/reference/option/dom

Programmers often confuse multidimensional arrays with arrays of pointers.

Multidimensional arrays

Most programmers are familiar with named multidimensional arrays, but many are unaware of the fact that multidimensional array can also be created anonymously. Multidimensional arrays are often referred to as "arrays of arrays" or "true multidimensional arrays".

Named multidimensional arrays

When using named multidimensional arrays, all dimensions must be known at compile time:

int H = read_int();
int W = read_int();

int connect_four[6][7];   // okay

int connect_four[H][7];   // ISO C++ forbids variable length array
int connect_four[6][W];   // ISO C++ forbids variable length array
int connect_four[H][W];   // ISO C++ forbids variable length array

This is how a named multidimensional array looks like in memory:

              +---+---+---+---+---+---+---+
connect_four: |   |   |   |   |   |   |   |

Note that 2D grids such as the above are merely helpful visualizations. From the point of view of C++, memory is a "flat" sequence of bytes. The elements of a multidimensional array are stored in row-major order. That is, connect_four[0][6] and connect_four[1][0] are neighbors in memory. In fact, connect_four[0][7] and connect_four[1][0] denote the same element! This means that you can take multi-dimensional arrays and treat them as large, one-dimensional arrays:

int* p = &connect_four[0][0];
int* q = p + 42;
some_int_sequence_algorithm(p, q);

Anonymous multidimensional arrays

With anonymous multidimensional arrays, all dimensions except the first must be known at compile time:

int (*p)[7] = new int[6][7];   // okay
int (*p)[7] = new int[H][7];   // okay

int (*p)[W] = new int[6][W];   // ISO C++ forbids variable length array
int (*p)[W] = new int[H][W];   // ISO C++ forbids variable length array

This is how an anonymous multidimensional array looks like in memory:

              +---+---+---+---+---+---+---+
        +---> |   |   |   |   |   |   |   |
        |     +---+---+---+---+---+---+---+

        |     +---+---+---+---+---+---+---+
        |
      +-|-+
   p: | | |
      +---+

Note that the array itself is still allocated as a single block in memory.

Arrays of pointers

You can overcome the restriction of fixed width by introducing another level of indirection.

Named arrays of pointers

Here is a named array of five pointers which are initialized with anonymous arrays of different lengths:

int* triangle[5];
for (int i = 0; i < 5; ++i)
{
    triangle[i] = new int[5 - i];
}

// ...

for (int i = 0; i < 5; ++i)
{
    delete[] triangle[i];
}

And here is how it looks like in memory:

          +---+---+---+---+---+
          |   |   |   |   |   |
          +---+---+---+---+---+
            ^
            | +---+---+---+---+
            | |   |   |   |   |
            | +---+---+---+---+
            |   ^
            |   | +---+---+---+
            |   | |   |   |   |
            |   | +---+---+---+
            |   |   ^
            |   |   | +---+---+
            |   |   | |   |   |
            |   |   | +---+---+
            |   |   |   ^
            |   |   |   | +---+
            |   |   |   | |   |
            |   |   |   | +---+
            |   |   |   |   ^
            |   |   |   |   |
            |   |   |   |   |
          +-|-+-|-+-|-+-|-+-|-+
triangle: | | | | | | | | | | |
          +---+---+---+---+---+

Since each line is allocated individually now, viewing 2D arrays as 1D arrays does not work anymore.

Anonymous arrays of pointers

Here is an anonymous array of 5 (or any other number of) pointers which are initialized with anonymous arrays of different lengths:

int n = calculate_five();   // or any other number
int** p = new int*[n];
for (int i = 0; i < n; ++i)
{
    p[i] = new int[n - i];
}

// ...

for (int i = 0; i < n; ++i)
{
    delete[] p[i];
}
delete[] p;   // note the extra delete[] !

And here is how it looks like in memory:

          +---+---+---+---+---+
          |   |   |   |   |   |
          +---+---+---+---+---+
            ^
            | +---+---+---+---+
            | |   |   |   |   |
            | +---+---+---+---+
            |   ^
            |   | +---+---+---+
            |   | |   |   |   |
            |   | +---+---+---+
            |   |   ^
            |   |   | +---+---+
            |   |   | |   |   |
            |   |   | +---+---+
            |   |   |   ^
            |   |   |   | +---+
            |   |   |   | |   |
            |   |   |   | +---+
            |   |   |   |   ^
            |   |   |   |   |
            |   |   |   |   |
          +-|-+-|-+-|-+-|-+-|-+
          | | | | | | | | | | |
          +---+---+---+---+---+
            ^
            |
            |
          +-|-+
       p: | | |
          +---+

Conversions

Array-to-pointer decay naturally extends to arrays of arrays and arrays of pointers:

int array_of_arrays[6][7];
int (*pointer_to_array)[7] = array_of_arrays;

int* array_of_pointers[6];
int** pointer_to_pointer = array_of_pointers;

However, there is no implicit conversion from T[h][w] to T**. If such an implicit conversion did exist, the result would be a pointer to the first element of an array of h pointers to T (each pointing to the first element of a line in the original 2D array), but that pointer array does not exist anywhere in memory yet. If you want such a conversion, you must create and fill the required pointer array manually:

int connect_four[6][7];

int** p = new int*[6];
for (int i = 0; i < 6; ++i)
{
    p[i] = connect_four[i];
}

// ...

delete[] p;

Note that this generates a view of the original multidimensional array. If you need a copy instead, you must create extra arrays and copy the data yourself:

int connect_four[6][7];

int** p = new int*[6];
for (int i = 0; i < 6; ++i)
{
    p[i] = new int[7];
    std::copy(connect_four[i], connect_four[i + 1], p[i]);
}

// ...

for (int i = 0; i < 6; ++i)
{
    delete[] p[i];
}
delete[] p;

The question is simply asked wrong. You don't make an alias that takes parameters because alias just adds a second name for something that already exists. The functionality the OP wants is the function command to create a new function. You do not need to alias the function as the function already has a name.

I think you want something like this :

function trash() { mv "$@" ~/.Trash; }

That's it! You can use parameters $1, $2, $3, etc, or just stuff them all with $@

You didn't mention the fancy indexing capabilities of dataframes, e.g.:

>>> df = pd.DataFrame({"class":[1,1,1,2,2], "value":[1,2,3,4,5]})
>>> df[df["class"]==1].sum()
class    3
value    6
dtype: int64
>>> df[df["class"]==1].sum()["value"]
6
>>> df[df["class"]==1].count()["value"]
3

You could replace df["class"]==1by another condition.

I've use this :

except (socket.timeout, KeyboardInterrupt) as e:
    logging.debug("Exception : {}".format(str(e.__str__).split(" ")[3]))
    break

Let me know if it does not work for you !!

I think this is what we like to do very much.

--Step 1: (create a new user)
create LOGIN hello WITH PASSWORD='foo', CHECK_POLICY = OFF;


-- Step 2:(deny view to any database)
USE master;
GO
DENY VIEW ANY DATABASE TO hello; 


 -- step 3 (then authorized the user for that specific database , you have to use the  master by doing use master as below)
USE master;
GO
ALTER AUTHORIZATION ON DATABASE::yourDB TO hello;
GO

If you already created a user and assigned to that database before by doing

USE [yourDB] 
CREATE USER hello FOR LOGIN hello WITH DEFAULT_SCHEMA=[dbo] 
GO

then kindly delete it by doing below and follow the steps

   USE yourDB;
   GO
   DROP USER newlogin;
   GO

I had the same issue and the problem was the size of the picture. Whatsapp doesn't support picture with a size greater than 300KB.

So the most important property to display image on Whatsapp is:

<meta property="og:image" content="url_image">

And the size of the image to display must be less than 300KB

import os
print os.path.abspath(__file__)

I was getting the same issue with a different application,

Faulting application name: javaw.exe, version: 8.0.51.16, time stamp: 0x55763d32
Faulting module name: mscorwks.dll, version: 2.0.50727.5485, time stamp: 0x53a11d6c

Faulting module path:C:\Windows\Microsoft.NET\Framework64\v2.0.50727\mscorwks.dll

I was using the The Enhanced Mitigation Experience Toolkit (EMET) from Microsoft and I found by disabling the EMET features on javaw.exe in my case as this was the faulting application, it enabled my application to run successfully. Make sure you don't have any similar software with security protections on memory.

About this solution, we could just create a directive and attach it to the DOM element that has to get the focus when a given condition is satisfied. By following this approach we avoid coupling controller to DOM element ID's.

Sample code directive:

gbndirectives.directive('focusOnCondition', ['$timeout',
    function ($timeout) {
        var checkDirectivePrerequisites = function (attrs) {
          if (!attrs.focusOnCondition && attrs.focusOnCondition != "") {
                throw "FocusOnCondition missing attribute to evaluate";
          }
        }

        return {            
            restrict: "A",
            link: function (scope, element, attrs, ctrls) {
                checkDirectivePrerequisites(attrs);

                scope.$watch(attrs.focusOnCondition, function (currentValue, lastValue) {
                    if(currentValue == true) {
                        $timeout(function () {                                                
                            element.focus();
                        });
                    }
                });
            }
        };
    }
]);

A possible usage

.controller('Ctrl', function($scope) {
   $scope.myCondition = false;
   // you can just add this to a radiobutton click value
   // or just watch for a value to change...
   $scope.doSomething = function(newMyConditionValue) {
       // do something awesome
       $scope.myCondition = newMyConditionValue;
  };

});

HTML

<input focus-on-condition="myCondition">

Starting from Java 8, you can also use parallelSort which is useful if you have arrays containing a lot of elements.

Example:

public static void main(String[] args) {
    String[] strings = { "x", "a", "c", "b", "y" };
    Arrays.parallelSort(strings);
    System.out.println(Arrays.toString(strings));   // [a, b, c, x, y]
}

If you want to ignore the case, you can use:

public static void main(String[] args) {
    String[] strings = { "x", "a", "c", "B", "y" };
    Arrays.parallelSort(strings, new Comparator<String>() {
        @Override
        public int compare(String o1, String o2) {              
            return o1.compareToIgnoreCase(o2);
        }
    });
    System.out.println(Arrays.toString(strings));   // [a, B, c, x, y]
}

otherwise B will be before a.

If you want to ignore the trailing spaces during the comparison, you can use trim():

public static void main(String[] args) {
    String[] strings = { "x", "  a", "c ", " b", "y" };
    Arrays.parallelSort(strings, new Comparator<String>() {
        @Override
        public int compare(String o1, String o2) {              
            return o1.trim().compareTo(o2.trim());
        }
    });
    System.out.println(Arrays.toString(strings)); // [  a,  b, c , x, y]
}

For Bootstrap 4, there are now spacing utilities so it's easier to change the height via padding on the nav links. This can be responsively applied only at specific breakpoints (ie: py-md-3). For example, on larger (md) screens, this nav is 120px high, then shrinks to normal height for the mobile menu. No extra CSS is needed..

<nav class="navbar navbar-fixed-top navbar-inverse bg-primary navbar-toggleable-md py-md-3">
    <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarNav" aria-expanded="false" aria-label="Toggle navigation">
        <span class="navbar-toggler-icon"></span>

Use the CSS z-index property. Elements with a greater z-index value are positioned in front of elements with smaller z-index values.

Note that for this to work, you also need to set a position style (position:absolute, position:relative, or position:fixed) on both/all of the elements you want to order.

I resolved a similar issue by wrapping the query in another query...

Initial query was working find giving individual columns of output, with some of the columns coming from sub queries with Max or Sum function, and other with "distinct" or case substitutions and such.

I encountered the collation error after attempting to create a single field of output with...

select
rtrim(field1)+','+rtrim(field2)+','+...

The query would execute as I wrote it, but the error would occur after saving the sql and reloading it.

Wound up fixing it with something like...

select z.field1+','+z.field2+','+... as OUTPUT_REC
from (select rtrim(field1), rtrim(field2), ... ) z

Some fields are "max" of a subquery, with a case substitution if null and others are date fields, and some are left joins (might be NULL)...in other words, mixed field types. I believe this is the cause of the issue being caused by OS collation and Database collation being slightly different, but by converting all to trimmed strings before the final select, it sorts it out, all in the SQL.

Enter services.msc and shutdown anything SQL you have running. The SQL server might be taking over the port.

This is a slightly more general answer with more explanation for future viewers.

Add a text changed listener

If you want to find the text length or do something else after the text has been changed, you can add a text changed listener to your edit text.

EditText editText = (EditText) findViewById(R.id.testEditText);
editText.addTextChangedListener(new TextWatcher() {

    @Override
    public void beforeTextChanged(CharSequence charSequence, int start, int count, int after) {

    }

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

    }

    @Override
    public void afterTextChanged(Editable editable) {

    }
});

The listener needs a TextWatcher, which requires three methods to be overridden: beforeTextChanged, onTextChanged, and afterTextChanged.

Counting the characters

You can get the character count in onTextChanged or beforeTextChanged with

charSequence.length()

or in afterTextChanged with

editable.length()

Meaning of the methods

The parameters are a little confusing so here is a little extra explanation.

beforeTextChanged

beforeTextChanged(CharSequence charSequence, int start, int count, int after)

• charSequence: This is the text content before the pending change is made. You should not try to change it.
• start: This is the index of where the new text will be inserted. If a range is selected, then it is the beginning index of the range.
• count: This is the length of selected text that is going to be replaced. If nothing is selected then count will be 0.
• after: this is the length of the text to be inserted.

onTextChanged

onTextChanged(CharSequence charSequence, int start, int before, int count)

• charSequence: This is the text content after the change was made. You should not try to modify this value here. Modify the editable in afterTextChanged if you need to.
• start: This is the index of the start of where the new text was inserted.
• before: This is the old value. It is the length of previously selected text that was replaced. This is the same value as count in beforeTextChanged.
• count: This is the length of text that was inserted. This is the same value as after in beforeTextChanged.

afterTextChanged

afterTextChanged(Editable editable)

Like onTextChanged, this is called after the change has already been made. However, now the text may be modified.

• editable: This is the editable text of the EditText. If you change it, though, you have to be careful not to get into an infinite loop. See the documentation for more details.

Supplemental image from this answer

Hmmm...

As Darin said, you can specify a higher connection timeout value, but I doubt that's really the issue.

When you get connection timeouts, it's typically a problem with one of the following:

1. Network configuration - slow connection between your web server/dev box and the SQL server. Increasing the timeout may correct this, but it'd be wise to investigate the underlying problem.

2. Connection string. I've seen issues where an incorrect username/password will, for some reason, give a timeout error instead of a real error indicating "access denied." This shouldn't happen, but such is life.

3. Connection String 2: If you're specifying the name of the server incorrectly, or incompletely (for instance, mysqlserver instead of mysqlserver.webdomain.com), you'll get a timeout. Can you ping the server using the server name exactly as specified in the connection string from the command line?

4. Connection string 3 : If the server name is in your DNS (or hosts file), but the pointing to an incorrect or inaccessible IP, you'll get a timeout rather than a machine-not-found-ish error.

5. The query you're calling is timing out. It can look like the connection to the server is the problem, but, depending on how your app is structured, you could be making it all the way to the stage where your query is executing before the timeout occurs.

6. Connection leaks. How many processes are running? How many open connections? I'm not sure if raw ADO.NET performs connection pooling, automatically closes connections when necessary ala Enterprise Library, or where all that is configured. This is probably a red herring. When working with WCF and web services, though, I've had issues with unclosed connections causing timeouts and other unpredictable behavior.

Things to try:

1. Do you get a timeout when connecting to the server with SQL Management Studio? If so, network config is likely the problem. If you do not see a problem when connecting with Management Studio, the problem will be in your app, not with the server.

2. Run SQL Profiler, and see what's actually going across the wire. You should be able to tell if you're really connecting, or if a query is the problem.

3. Run your query in Management Studio, and see how long it takes.

Good luck!

For my case, I have a dropdown list in my div container, so I can not use overflow: hidden or my dropdown list will be hidden.

Inspired by this discussion: https://twitter.com/siddharthkp/status/1094821277452234752 I use border-bottom-left-radius and border-bottom-right-radius in the child element to fix this issue.

make sure you add it the correct value for each child separately

Give a try to this

@Override
public void destroyItem(ViewGroup container, int position, Object object) {
    // TODO Auto-generated method stub

    FragmentManager manager = ((Fragment) object).getFragmentManager();
    FragmentTransaction trans = manager.beginTransaction();
    trans.remove((Fragment) object);
    trans.commit();

    super.destroyItem(container, position, object);
}

No, there isn't.

I'm pretty sure there is no way to intercept a click on the refresh button from JS, and even if there was, JS can be turned off.

You should probably step back from your X (preventing refreshing) and find a different solution to Y (whatever that might be).

The correct answer:

<form role="search" method="get" action="" target="_blank"></form>

Supported in all major browsers :)

YUI2 has a cross-browser implementation of getElementsByClassName.

A couple of notes first: when you use Data/data1.txt as an argument, should it really be /Data/data1.txt (with a leading slash)? Also, should the outer loop scan only for .txt files, or all files in /Data? Here's an answer, assuming /Data/data1.txt and .txt files only:

#!/bin/bash
for filename in /Data/*.txt; do
    for ((i=0; i<=3; i++)); do
        ./MyProgram.exe "$filename" "Logs/$(basename "$filename" .txt)_Log$i.txt"
    done
done

Notes:

• /Data/*.txt expands to the paths of the text files in /Data (including the /Data/ part)
• $( ... ) runs a shell command and inserts its output at that point in the command line
• basename somepath .txt outputs the base part of somepath, with .txt removed from the end (e.g. /Data/file.txt -> file)

If you needed to run MyProgram with Data/file.txt instead of /Data/file.txt, use "${filename#/}" to remove the leading slash. On the other hand, if it's really Data not /Data you want to scan, just use for filename in Data/*.txt.

This is on mysql workbench -- give the image file path:

INSERT INTO XX_SAMPLE(id,image) VALUES(3,'/home/ganesan-pc/Documents/aios_database/confe.jpg');

The accepted answer via git merge will get the job done but leaves a messy commit hisotry, correct way should be 'rebase' via the following steps(assuming you want to keep your feature branch in sycn with develop before you do the final push before PR).

1 git fetch from your feature branch (make sure the feature branch you are working on is update to date)

2 git rebase origin/develop

3 if any conflict shall arise, resolve them one by one

Excel's interface for SQL Server queries will not let you have a custom parameters.  A way around this is to create a generic Microsoft Query, then add parameters, then paste your parametorized query in the connection's properties.  Here are the detailed steps for Excel 2010:

1. Open Excel
2. Goto Data tab
3. From the From Other Sources button choose From Microsoft Query
4. The "Choose Data Source" window will appear.  Choose a datasource and click OK.
5. The Query Qizard
1. Choose Column: window will appear.  The goal is to create a generic query. I recommend choosing one column from a small table.
2. Filter Data: Just click Next
3. Sort Order: Just click Next
4. Finish: Just click Finish.
6. The "Import Data" window will appear:
1. Click the Properties... button.
1. Choose the Definition tab
2. In the "Command text:" section add a WHERE clause that includes Excel parameters.  It's important to add all the parameters that you want now.  For example, if I want two parameters I could add this:
   WHERE 1 = ? and 2 = ?
3. Click OK to get back to the "Import Data" window
2. Choose PivotTable Report
3. Click OK
7. You will be prompted to enter the parameters value for each parameter.
8. Once you have enter the parameters you will be at your pivot table
9. Go batck to the Data tab and click the connections Properties button
1. Click the Definition tab
2. In the "Command text:" section, Paste in the real SQL Query that you want with the same number of parameters that you defined earlier.
3. Click the Parameters... button 
1. enter the Prompt values for each parameter
2. Click OK
4. Click OK to close the properties window
10. Congratulations, you now have parameters.

In my case, it took some digging, but found it.

My Context

I'm looking at exception/error logs from the website using Elmah. Elmah returns the state of the server at the of time the exception, in the form of a large XML document. For our reporting engine I pretty-print the XML with XmlWriter.

During a website attack, I noticed that some xmls weren't parsing and was receiving this '.', hexadecimal value 0x00, is an invalid character. exception.

NON-RESOLUTION: I converted the document to a byte[] and sanitized it of 0x00, but it found none.

When I scanned the xml document, I found the following:

...
<form>
...
<item name="SomeField">
   <value
     string="C:\boot.ini&#x0;.htm" />
 </item>
...

There was the nul byte encoded as an html entity � !!!

RESOLUTION: To fix the encoding, I replaced the � value before loading it into my XmlDocument, because loading it will create the nul byte and it will be difficult to sanitize it from the object. Here's my entire process:

XmlDocument xml = new XmlDocument();
details.Xml = details.Xml.Replace("�", "[0x00]");  // in my case I want to see it, otherwise just replace with ""
xml.LoadXml(details.Xml);

string formattedXml = null;

// I have this in a helper function, but for this example I have put it in-line
StringBuilder sb = new StringBuilder();
XmlWriterSettings settings = new XmlWriterSettings {
    OmitXmlDeclaration = true,
    Indent = true,
    IndentChars = "\t",
    NewLineHandling = NewLineHandling.None,
};
using (XmlWriter writer = XmlWriter.Create(sb, settings)) {
    xml.Save(writer);
    formattedXml = sb.ToString();
}

LESSON LEARNED: sanitize for illegal bytes using the associated html entity, if your incoming data is html encoded on entry.

For anytone who has worked in ASP as well as more modern languages, the question will provoke a chuckle. In my experience using a custom error handler (set up in IIS to handle the 500;100 errors) is the best option for ASP error handling. This article describes the approach and even gives you some sample code / database table definition.

http://www.15seconds.com/issue/020821.htm

Here is a link to Archive.org's version

The best and most sure solution is using SCOPE_IDENTITY().

Just you have to get the scope identity after every insert and save it in a variable because you can call two insert in the same scope.

ident_current and @@identity may be they work but they are not safe scope. You can have issues in a big application

  declare @duplicataId int
  select @duplicataId =   (SELECT SCOPE_IDENTITY())

More detail is here Microsoft docs

This improved version should work as reliably as a parser.

Add this to the stylesheet:

table {
  border-collapse: collapse;
}

JSFiddle.

The reason why it behaves this way is actually described pretty well in the specification:

There are two distinct models for setting borders on table cells in CSS. One is most suitable for so-called separated borders around individual cells, the other is suitable for borders that are continuous from one end of the table to the other.

... and later, for collapse setting:

In the collapsing border model, it is possible to specify borders that surround all or part of a cell, row, row group, column, and column group.

Use:

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
    iDisplayLength: -1
});

Or if using 1.10+

$('#example').dataTable({
    paging: false
});

The option you should use is iDisplayLength:

$('#adminProducts').dataTable({
  'iDisplayLength': 100
});

$('#table').DataTable({
   "lengthMenu": [ [5, 10, 25, 50, -1], [5, 10, 25, 50, "All"] ]
});

It will Load by default all entries.

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
    iDisplayLength: -1
});

Or if using 1.10+

$('#example').dataTable({
    paging: false
});

If you want to load by default 25 not all do this.

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
});

The following code will work:

ComboBox1.SelectedIndex.Equals(String.Empty);

You need to install the provisioning profile (drag and drop it into iTunes). Then drag and drop the .ipa. Ensure you device is set to sync apps, and try again.

Answer of @iWantScala is great but not working for me
rootView.getRootView().getHeight() always has the same value

one way is to define two vars

private int maxRootViewHeight = 0;
private int currentRootViewHeight = 0;

add global listener

rootView.getViewTreeObserver()
    .addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            currentRootViewHeight = rootView.getHeight();
            if (currentRootViewHeight > maxRootViewHeight) {
                maxRootViewHeight = currentRootViewHeight;
            }
        }
    });

then check

if (currentRootViewHeight >= maxRootViewHeight) {
    // Keyboard is hidden
} else {
    // Keyboard is shown
}

works fine

If you are adding a loading view (an activity indicator view for instance), make sure you have an object of UIWindow class. If you show an action sheet just before you show your loading view, the keyWindow will be the UIActionSheet and not UIWindow. And since the action sheet will go away, the loading view will go away with it. Or that's what was causing me problems.

UIWindow *keyWindow = [[UIApplication sharedApplication] keyWindow];
if (![NSStringFromClass([keyWindow class]) isEqualToString:@"UIWindow"]) {
    // find uiwindow in windows
    NSArray *windows = [UIApplication sharedApplication].windows;
    for (UIWindow *window in windows) {
        if ([NSStringFromClass([window class]) isEqualToString:@"UIWindow"]) {
            keyWindow = window;
            break;
        }
    }
}

The backslash escapes the #, interpreting it as its literal character instead of a comment character.

Your two examples are the only things I have ever used the Rows and Columns properties for, but in theory you could do anything with them that can be done with a Range object.

The return type of those properties is itself a Range, so you can do things like:

Dim myRange as Range
Set myRange = Sheet1.Range(Cells(2,2),Cells(8,8))
myRange.Rows(3).Select

Which will select the third row in myRange (Cells B4:H4 in Sheet1).

update: To do what you want to do, you could use:

Dim interestingRows as Range
Set interestingRows = Sheet1.Range(startRow & ":" & endRow)

update #2: Or, to get a subset of rows from within a another range:

Dim someRange As Range
Dim interestingRows As Range

Set myRange = Sheet1.Range(Cells(2, 2), Cells(8, 8))

startRow = 3
endRow = 6

Set interestingRows = Range(myRange.Rows(startRow), myRange.Rows(endRow))

Borrowing @jgauffin answer as an HtmlHelper extension:

public static class HtmlHelperExtensions
{
    public static MvcHtmlString RenderPartialViewToString(
        this HtmlHelper html, 
        ControllerContext controllerContext, 
        ViewDataDictionary viewData,
        TempDataDictionary tempData,
        string viewName, 
        object model)
    {
        viewData.Model = model;
        string result = String.Empty;

        using (StringWriter sw = new StringWriter())
        {
            ViewEngineResult viewResult = ViewEngines.Engines.FindPartialView(controllerContext, viewName);
            ViewContext viewContext = new ViewContext(controllerContext, viewResult.View, viewData, tempData, sw);
            viewResult.View.Render(viewContext, sw);

            result = sw.GetStringBuilder().ToString();
        }

        return MvcHtmlString.Create(result);
    }
}

Usage in a razor view:

Html.RenderPartialViewToString(ViewContext, ViewData, TempData, "Search", Model)

Another possible solution. Count empty cells and subtract that value from the total number of cells

Sub Emptys()

Dim r As range
Dim totalCells As Integer

'My range To check'
Set r = ActiveSheet.range("A1:B5")

'Check for filled cells'
totalCells = r.Count- WorksheetFunction.CountBlank(r)


If totalCells = 0 Then
    MsgBox "Range is empty"
Else
    MsgBox "Range is not empty"
End If

End Sub

Use arrays:

{
    "number": ["1", "2", "3"],
    "alphabet": ["a", "b", "c"]
}

You can the access the different values from their position in the array. Counting starts at left of array at 0. myJsonObject["number"][0] == 1 or myJsonObject["alphabet"][2] == 'c'

Active record method or_where is to be used:

$this->db->select("*")
->from("table_name")
->where("first", $first)
->or_where("second", $second);

On my machine, port is in /opt/local/bin/port - try typing that into a terminal on its own.

Try this

var color : Color = (Color as any)["Green];

That works fine for 3.5.3 version

Suppose you need to fill the spinner from the string-array from the resource, and you want to keep selected the value from server. So, this is one way to set selected a value from server in the spinner.

pincodeSpinner.setSelection(resources.getStringArray(R.array.pincodes).indexOf(javaObject.pincode))

Hope it helps! P.S. the code is in Kotlin!

Convert would be the normal answer, but the format is not a recognised format for the converter, mm/dd/yyyy could be converted using convert(datetime,yourdatestring,101) but you do not have that format so it fails.

The problem is the format being non-standard, you will have to manipulate it to a standard the convert can understand from those available.

Hacked together, if you can guarentee the format

declare @date char(8)
set @date = '12312009'
select convert(datetime, substring(@date,5,4) + substring(@date,1,2) + substring(@date,3,2),112)

Building workspace is about incremental build of any evolution detected in one of the opened projects in the currently used workspace.

You can also disable it through the menu "Project / Build automatically".

But I would recommend first to check:

• if a Project Clean all / Build result in the same kind of long wait (after disabling this option)
• if you have (this time with building automatically activated) some validation options you could disable to see if they have an influence on the global compilation time (Preferences / Validations, or Preferences / XML / ... if you have WTP installed)
• if a fresh eclipse installation referencing the same workspace (see this eclipse.ini for more) results in the same issue (with building automatically activated)

Note that bug 329657 (open in 2011, in progress in 2014) is about interrupting a (too lengthy) build, instead of cancelling it:

There is an important difference between build interrupt and cancel.

• When a build is cancelled, it typically handles this by discarding incremental build state and letting the next build be a full rebuild. This can be quite expensive in some projects.
  As a user I think I would rather wait for the 5 second incremental build to finish rather than cancel and result in a 30 second rebuild afterwards.

• The idea with interrupt is that a builder could more efficiently handle interrupt by saving its intermediate state and resuming on the next invocation.
  In practice this is hard to implement so the most common boundary is when we check for interrupt before/after calling each builder in the chain.

I googled for the solution for a while and finally came up with the below solution,

SSMS in general uses several connections to the database behind the scenes.

You will need to kill these connections before changing the access mode.(I have done it with EXEC(@kill); in the code template below.)

Then,

Run the following SQL to set the database in MULTI_USER mode.

USE master
GO
DECLARE @kill varchar(max) = '';
SELECT @kill = @kill + 'KILL ' + CONVERT(varchar(10), spid) + '; '
FROM master..sysprocesses 
WHERE spid > 50 AND dbid = DB_ID('<Your_DB_Name>')
EXEC(@kill);

GO
SET DEADLOCK_PRIORITY HIGH
ALTER DATABASE [<Your_DB_Name>] SET MULTI_USER WITH NO_WAIT
ALTER DATABASE [<Your_DB_Name>] SET MULTI_USER WITH ROLLBACK IMMEDIATE
GO

To switch back to Single User mode, you can use:

ALTER DATABASE [<Your_DB_Name>] SET SINGLE_USER

This should work. Happy coding!!

Thanks!!

I've written a library that uses json.org to parse JSON, but it will actually create a proxy of an interface for you. The code/JAR is on code.google.com.

http://fixjures.googlecode.com/

I don't know if it works on J2ME. Since it uses Java Reflection to create proxies, I'm thinking it won't work. Also, it's currently got a hard dependency on Google Collections which I want to remove and it's probably too heavyweight for your needs, but it allows you to interact with your JSON data in the way you're looking for:

interface Foo {
    String getName();
    int getWidth();
    int getHeight();
}

Foo myFoo = Fixjure.of(Foo.class).from(JSONSource.newJsonString("{ name : \"foo name\" }")).create();
String name = myFoo.getName(); // name now .equals("foo name");

1. Create new project in Android studio;

2. Press Ctrl+Shift+Alt+S

3. Proceed to "Project" section

4. You can see actual gradle version and android pluging version. Copy that to your project.

Regular expressions with character classes (e.g. [[:digit:]]) are not supported in the default regular expression syntax used by find. You need to specify a different regex type such as posix-extended in order to use them.

Take a look at GNU Find's Regular Expression documentation which shows you all the regex types and what they support.

I had this problem recently. I stumbled across an option: default_authentication_plugin

For some reason it had set it to caching_sha2_password, but updating the value to mysql_native_password fixed it for me. I'm not sure what the differences are, though, so be careful!

Hope this helps someone!

I was looking for this answer:

import os,glob
folder_path = '/some/path/to/file'
for filename in glob.glob(os.path.join(folder_path, '*.htm')):
  with open(filename, 'r') as f:
    text = f.read()
    print (filename)
    print (len(text))

you can choose as well '*.txt' or other ends of your filename

1. Latitudes range from -90 to +90 (degrees), so DECIMAL(10, 8) is ok for that

2. longitudes range from -180 to +180 (degrees) so you need DECIMAL(11, 8).

Note: The first number is the total number of digits stored, and the second is the number after the decimal point.

In short: lat DECIMAL(10, 8) NOT NULL, lng DECIMAL(11, 8) NOT NULL

I have also tried all the posted code until I found out this one

if(math.toLowerCase(Locale.ENGLISH));

Here whatever character the user input will be converted to lower cases.

Apache Crunch also has a Pair class: http://crunch.apache.org/apidocs/0.5.0/org/apache/crunch/Pair.html

Well there are two methods to access this data easier, but the interface doesn't offer the possibility to get the whole URL with one call. You have to build it manually:

public static String makeUrl(HttpServletRequest request)
{
    return request.getRequestURL().toString() + "?" + request.getQueryString();
}

I don't know about a way to do this with any Spring MVC facilities.

If you want to access the current Request without passing it everywhere you will have to add a listener in the web.xml:

<listener>
    <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
</listener>

And then use this to get the request bound to the current Thread:

((ServletRequestAttributes) RequestContextHolder.currentRequestAttributes()).getRequest()

It happens when $ret hasn't been defined. The solution is simple. Right above $tags = get_tags();, add the following line:

$ret = array();

I just tried a bare-bones implementation and it just works:

public class Test {

    public static void main(String[] args) {
            JFrame frame = new JFrame("Hello");
            frame.setPreferredSize(new Dimension(200, 200));
            frame.add(new Board());
            frame.pack();
            frame.setVisible(true);
    }
}

public class Board extends JPanel {

    private Player player = new Player();

    public Board(){
        setBackground(Color.BLACK);
    }

    public void paintComponent(Graphics g){  
        super.paintComponent(g);
        g.setColor(Color.red);
        g.fillOval(player.getCenter().x, player.getCenter().y,
             player.getRadius(), player.getRadius());
    } 
}

public class Player {

    private Point center = new Point(50, 50);

    public Point getCenter() {
        return center;
    }

    private int radius = 10;

    public int getRadius() {
        return radius;
    }
}

The easiest way I found was to download the JLayer jar file from http://www.javazoom.net/javalayer/sources.html and to add it to the Jar library http://www.wikihow.com/Add-JARs-to-Project-Build-Paths-in-Eclipse-%28Java%29

Here is the code for the class

public class SimplePlayer {

    public SimplePlayer(){

        try{

             FileInputStream fis = new FileInputStream("File location.");
             Player playMP3 = new Player(fis);

             playMP3.play();

        }  catch(Exception e){
             System.out.println(e);
           }
    } 
}

and here are the imports

import javazoom.jl.player.*;
import java.io.FileInputStream;

$each will work.. Another option is jQuery Ajax Callback for array result

function displayResultForLog(result) {
  if (result.hasOwnProperty("d")) {
    result = result.d
  }

  if (result !== undefined && result != null) {
    if (result.hasOwnProperty('length')) {
      if (result.length >= 1) {
        for (i = 0; i < result.length; i++) {
          var sentDate = result[i];
        }
      } else {
        $(requiredTable).append('Length is 0');
      }
    } else {
      $(requiredTable).append('Length is not available.');
    }

  } else {
    $(requiredTable).append('Result is null.');
  }
}

Not possible in Java.

Here's the Scala way:

val m = List(5, 4, 2, 89)

for((el, i) <- m.zipWithIndex)
  println(el +" "+ i)

It depends on the context

When you consider your team as a list of players, you are projecting the "idea" of a foot ball team down to one aspect: You reduce the "team" to the people you see on the field. This projection is only correct in a certain context. In a different context, this might be completely wrong. Imagine you want to become a sponsor of the team. So you have to talk to the managers of the team. In this context the team is projected to the list of its managers. And these two lists usually don't overlap very much. Other contexts are the current versus the former players, etc.

Unclear semantics

So the problem with considering a team as a list of its players is that its semantic depends on the context and that it cannot be extended when the context changes. Additionally it is hard to express, which context you are using.

Classes are extensible

When you using a class with only one member (e.g. IList activePlayers), you can use the name of the member (and additionally its comment) to make the context clear. When there are additional contexts, you just add an additional member.

Classes are more complex

In some cases it might be overkill to create an extra class. Each class definition must be loaded through the classloader and will be cached by the virtual machine. This costs you runtime performance and memory. When you have a very specific context it might be OK to consider a football team as a list of players. But in this case, you should really just use a IList , not a class derived from it.

Conclusion / Considerations

When you have a very specific context, it is OK to consider a team as a list of players. For example inside a method it is completely OK to write:

IList<Player> footballTeam = ...

When using F#, it can even be OK to create a type abbreviation:

type FootballTeam = IList<Player>

But when the context is broader or even unclear, you should not do this. This is especially the case when you create a new class whose context in which it may be used in the future is not clear. A warning sign is when you start to add additional attributes to your class (name of the team, coach, etc.). This is a clear sign that the context where the class will be used is not fixed and will change in the future. In this case you cannot consider the team as a list of players, but you should model the list of the (currently active, not injured, etc.) players as an attribute of the team.

You can find examples for writing OAuth clients here:

• https://github.com/spring-projects/spring-security-oauth

In your case you can't just use default or base classes for everything, you have a multiple classes Implementing OAuth2ProtectedResourceDetails. The configuration depends of how you configured your OAuth service but assuming from your curl connections I would recommend:

@EnableOAuth2Client

    private String baseUrl;
    @Value("${oauth.authorize:http://localhost:8082/oauth/authorize}")

    @Value("${oauth.token:http://localhost:8082/oauth/token}")
    private String tokenUrl;

    @Bean
    protected OAuth2ProtectedResourceDetails resource() {
        ResourceOwnerPasswordResourceDetails resource;
        resource = new ResourceOwnerPasswordResourceDetails();

        List scopes = new ArrayList<String>(2);
        scopes.add("write");
        scopes.add("read");
        resource.setAccessTokenUri(tokenUrl);
        resource.setClientId("restapp");
        resource.setClientSecret("restapp");

    public MyService() {
        restTemplate.getAccessToken();
    }
}

Do not forget about @EnableOAuth2Client on your config class, also I would suggest to try that the urls you are using are working with curl first, also try to trace it with the debugger because lot of exceptions are just consumed and never printed out due security reasons, so it gets little hard to find where the issue is. You should use logger with debug enabled set. Good luck

I uploaded sample springboot app on github https://github.com/mariubog/oauth-client-sample to depict your situation because I could not find any samples for your scenario .

After trying without success to use _compiled_select() or get_compiled_select() I just printed the db object, and you can see the query there in the queries property.

Try it yourself:

var_dump( $this->db );

If you know you have only one query, you can print it directly:

echo $this->db->queries[0];

Modify your log4j.properties file accordingly:

log4j.rootLogger=TRACE,stdout
...
log4j.logger.debugLog=TRACE,debugLog
log4j.logger.reportsLog=DEBUG,reportsLog

Change the log levels for each logger depending to your needs.

If you don't want to set a width for #container, just add

text-align: center;

to #main_content.

This is working for me in Swift 5. The usage case is taking a URL from the clipboard or similar which may already have escaped characters but which also contains Unicode characters which could cause URLComponents or URL(string:) to fail.

First, create a character set that includes all URL-legal characters:

extension CharacterSet {

    /// Characters valid in at least one part of a URL.
    ///
    /// These characters are not allowed in ALL parts of a URL; each part has different requirements. This set is useful for checking for Unicode characters that need to be percent encoded before performing a validity check on individual URL components.
    static var urlAllowedCharacters: CharacterSet {
        // Start by including hash, which isn't in any set
        var characters = CharacterSet(charactersIn: "#")
        // All URL-legal characters
        characters.formUnion(.urlUserAllowed)
        characters.formUnion(.urlPasswordAllowed)
        characters.formUnion(.urlHostAllowed)
        characters.formUnion(.urlPathAllowed)
        characters.formUnion(.urlQueryAllowed)
        characters.formUnion(.urlFragmentAllowed)

        return characters
    }
}

Next, extend String with a method to encode URLs:

extension String {

    /// Converts a string to a percent-encoded URL, including Unicode characters.
    ///
    /// - Returns: An encoded URL if all steps succeed, otherwise nil.
    func encodedUrl() -> URL? {        
        // Remove preexisting encoding,
        guard let decodedString = self.removingPercentEncoding,
            // encode any Unicode characters so URLComponents doesn't choke,
            let unicodeEncodedString = decodedString.addingPercentEncoding(withAllowedCharacters: .urlAllowedCharacters),
            // break into components to use proper encoding for each part,
            let components = URLComponents(string: unicodeEncodedString),
            // and reencode, to revert decoding while encoding missed characters.
            let percentEncodedUrl = components.url else {
            // Encoding failed
            return nil
        }

        return percentEncodedUrl
    }

}

Which can be tested like:

let urlText = "https://www.example.com/??/search?q=123&foo=bar&multi=eggs+and+ham&hangul=??&spaced=lovely%20spam&illegal=<>#top"
let url = encodedUrl(from: urlText)

Value of url at the end: https://www.example.com/%ED%8F%B4%EB%8D%94/search?q=123&foo=bar&multi=eggs+and+ham&hangul=%ED%95%9C%EA%B8%80&spaced=lovely%20spam&illegal=%3C%3E#top

Note that both %20 and + spacing are preserved, Unicode characters are encoded, the %20 in the original urlText is not double encoded, and the anchor (fragment, or #) remains.

Edit: Now checking for validity of each component.

like "a darren" answer but minor modification

li 
{
background: url("images/bullet.gif") left center no-repeat;
padding-left: 14px;
margin-left: 24px;
}

it works cross browser, just adjust the padding and margin

Edit for nested: add this style to add margin-left to the sub-nested list

ul ul{ margin-left:15px; }

Use .. to indicate the parent directory:

background-image: url('../images/bg.png');

Use daniel's solution if the set of encoded characters is relatively restricted. Otherwise, use one of the numerous HTML-parsing libraries.

I like BeautifulSoup because it can handle malformed XML/HTML :

http://www.crummy.com/software/BeautifulSoup/

for your question, there's an example in their documentation

from BeautifulSoup import BeautifulStoneSoup
BeautifulStoneSoup("Sacré bleu!", 
                   convertEntities=BeautifulStoneSoup.HTML_ENTITIES).contents[0]
# u'Sacr\xe9 bleu!'

You are encountering the float bug (though I'm not sure if it's technically a bug due to how many browsers exhibit this behaviour). Here is what is happening:

Under normal circumstances, assuming that no explicit height has been set, a block level element such as a div will set its height based on its content. The bottom of the parent div will extend beyond the last element. Unfortunately, floating an element stops the parent from taking the floated element into account when determining its height. This means that if your last element is floated, it will not "stretch" the parent in the same way a normal element would.

Clearing

There are two common ways to fix this. The first is to add a "clearing" element; that is, another element below the floated one that will force the parent to stretch. So add the following html as the last child:

<div style="clear:both"></div>

It shouldn't be visible, and by using clear:both, you make sure that it won't sit next to the floated element, but after it.

Overflow:

The second method, which is preferred by most people (I think) is to change the CSS of the parent element so that the overflow is anything but "visible". So setting the overflow to "hidden" will force the parent to stretch beyond the bottom of the floated child. This is only true if you haven't set a height on the parent, of course.

Like I said, the second method is preferred as it doesn't require you to go and add semantically meaningless elements to your markup, but there are times when you need the overflow to be visible, in which case adding a clearing element is more than acceptable.

So,

Steps to follow in order to import a JAR sucesfully to your project using Android Studio 0.1.1:

• Download the library.jar file and copy it to your /libs/ folder inside your application project.
• Open the build.gradle file and edit your dependencies to include the new .jar file:

compile files('libs/android-support-v4.jar', 'libs/GoogleAdMobAdsSdk-6.4.1.jar')

• File -> Close Project
• Open a command prompt on your project's root location, i.e 'C:\Users\Username\AndroidStudioProjects\MyApplicationProject\'
• On the command prompt, type gradlew clean, wait till it's done.
• Reopen your application project in Android Studio.
• Test run your application and it should work succesfully.

No, you can have pointers to stack allocated objects:

MyClass *myclass;
MyClass c;
myclass = & c;
myclass->DoSomething();

This is of course common when using pointers as function parameters:

void f( MyClass * p ) {
    p->DoSomething();
}

int main() {
    MyClass c;
    f( & c );
}

One way or another though, the pointer must always be initialised. Your code:

MyClass *myclass;
myclass->DoSomething();

leads to that dreaded condition, undefined behaviour.

In iOS 4.2 & 4.3 the following works:

UIDatePicker *datePicker = [[UIDatePicker alloc] init];
datePicker.frame = CGRectMake(0, 0, 320, 180);
[self addSubview:datePicker];

The following does not work:

UIDatePicker *datePicker = [[UIDatePicker alloc] initWithFrame:CGRectMake(0, 0, 320, 180)];
[self addSubview:datePicker];

I have an app that is in the app store with a 3 line date picker. I thought the height change may have been prevented because you see the text under the date picker's border, but this happens to the normal 216 height date picker too.

Which is the bug? Your guess is as good as mine.

Also there are 3 valid heights for UIDatePicker (and UIPickerView) 162.0, 180.0, and 216.0. If you set a UIPickerView height to anything else you will see the following in the console when debugging on an iOS device.

2011-09-14 10:06:56.180 DebugHarness[1717:707] -[UIPickerView setFrame:]: invalid height value 300.0 pinned to 216.0

This helped me at the end:

Quick guide:

• Download Google USB Driver

• Connect your device with Android Debugging enabled to your PC

• Open Device Manager of Windows from System Properties.

• Your device should appear under Other devices listed as something like Android ADB Interface or 'Android Phone' or similar. Right-click that and click on Update Driver Software...

• Select Browse my computer for driver software

• Select Let me pick from a list of device drivers on my computer

• Double-click Show all devices

• Press the Have disk button

• Browse and navigate to [wherever your SDK has been installed]\google-usb_driver and select android_winusb.inf

• Select Android ADB Interface from the list of device types.

• Press the Yes button

• Press the Install button

• Press the Close button

Now you've got the ADB driver set up correctly. Reconnect your device if it doesn't recognize it already.

If your query consists only of the $where operator, you can pass in just the JavaScript expression:

db.T.find("this.Grade1 > this.Grade2");

For greater performance, run an aggregate operation that has a $redact pipeline to filter the documents which satisfy the given condition.

The $redact pipeline incorporates the functionality of $project and $match to implement field level redaction where it will return all documents matching the condition using $$KEEP and removes from the pipeline results those that don't match using the $$PRUNE variable.

Running the following aggregate operation filter the documents more efficiently than using $where for large collections as this uses a single pipeline and native MongoDB operators, rather than JavaScript evaluations with $where, which can slow down the query:

db.T.aggregate([
    {
        "$redact": {
            "$cond": [
                { "$gt": [ "$Grade1", "$Grade2" ] },
                "$$KEEP",
                "$$PRUNE"
            ]
        }
    }
])

which is a more simplified version of incorporating the two pipelines $project and $match:

db.T.aggregate([
    {
        "$project": {
            "isGrade1Greater": { "$cmp": [ "$Grade1", "$Grade2" ] },
            "Grade1": 1,
            "Grade2": 1,
            "OtherFields": 1,
            ...
        }
    },
    { "$match": { "isGrade1Greater": 1 } }
])

With MongoDB 3.4 and newer:

db.T.aggregate([
    {
        "$addFields": {
            "isGrade1Greater": { "$cmp": [ "$Grade1", "$Grade2" ] }
        }
    },
    { "$match": { "isGrade1Greater": 1 } }
])

You leave the declarations in the header file:

class A2DD
{
  private:
  int gx;
  int gy;

  public:
    A2DD(int x,int y); // leave the declarations here
    int getSum();
};

And put the definitions in the implementation file.

A2DD::A2DD(int x,int y) // prefix the definitions with the class name
{
  gx = x;
  gy = y;
}

int A2DD::getSum()
{
  return gx + gy;
}

You could mix the two (leave getSum() definition in the header for instance). This is useful since it gives the compiler a better chance at inlining for example. But it also means that changing the implementation (if left in the header) could trigger a rebuild of all the other files that include the header.

Note that for templates, you need to keep it all in the headers.

In Python, to represent the absence of a value, you can use the None value (types.NoneType.None) for objects and "" (or len() == 0) for strings. Therefore:

if yourObject is None:  # if yourObject == None:
    ...

if yourString == "":  # if yourString.len() == 0:
    ...

Regarding the difference between "==" and "is", testing for object identity using "==" should be sufficient. However, since the operation "is" is defined as the object identity operation, it is probably more correct to use it, rather than "==". Not sure if there is even a speed difference.

Anyway, you can have a look at:

• Python Built-in Constants doc page.
• Python Truth Value Testing doc page.

In the solution below I used python3.4 as binary, but it's safe to use with any version or binary of python. it works fine on windows too (except the downloading pip with wget obviously but just save the file locally and run it with python).

This is great if you have multiple versions of python installed, so you can manage external libraries per python version.

So first, I'd recommend get-pip.py, it's great to install pip :

wget https://bootstrap.pypa.io/get-pip.py

Then you need to install pip for your version of python, I have python3.4 so for me this is the command :

python3.4 get-pip.py

Now pip is installed for python3.4 and in order to get libraries for python3.4 one need to call it within this version, like this :

python3.4 -m pip

So if you want to install numpy you would use :

python3.4 -m pip install numpy

Note that numpy is quite the heavy library. I thought my system was hanging and failing. But using the verbose option, you can see that the system is fine :

python3.4 -m pip install numpy -v

This may tell you that you lack python.h but you can easily get it :

On RHEL (Red hat, CentOS, Fedora) it would be something like this :

yum install python34-devel

On debian-like (Debian, Ubuntu, Kali, ...) :

apt-get install python34-dev

Then rerun this :

python3.4 -m pip install numpy -v

The order of items in the PATH matters. If there are multiple entries for various java installations, the first one in your PATH will be used.

I have had similar issues after installing a product, like Oracle, that puts it's JRE at the beginning of the PATH.

Ensure that the JDK you want to be loaded is the first entry in your PATH (or at least that it appears before C:\Program Files\Java\jre6\bin appears).

Create an XML file like below one. Set it as background for the button. Change the radius attribute to your wish, if you need more curve for the button.

button_background.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="@color/primary" />
    <corners android:radius="5dp" />
</shape>

Set background to your button:

<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/button_background"/>

If you want this environment variable available to all users and on system start then you can add the following to /etc/profile.d/java.sh (create it if necessary):

export JDK_HOME=/usr/lib/jvm/java-7-oracle
export JAVA_HOME=/usr/lib/jvm/java-7-oracle

Then in a terminal run:

sudo chmod +x /etc/profile.d/java.sh
source /etc/profile.d/java.sh

My second question is - should it point to java-6-sun or java-6-sun-1.6.0.24 ?

It should always point to java-7-oracle as that symlinks to the latest installed one (assuming you installed Java from the Ubuntu repositories and now from the download available at oracle.com).

After reading many questions on stackoverflow I found out that my CPU does not support Virtualization. I have to upgrade to the cpu which supports Virtualization in order to install Intel X 86 Emulator accelerator(Haxm Installer)

I couldn't find a simple example about the differences between ES6 and ES5, so I made one. Both code samples create exactly the same object. But the ES5 example also works in older browsers (like IE11), wheres the ES6 example doesn't.

ES6

var matrix = {};
var a = 'one';
var b = 'two';
var c = 'three';
var d = 'four';

matrix[a] = {[b]: {[c]: d}};

ES5

var matrix = {};
var a = 'one';
var b = 'two';
var c = 'three';
var d = 'four';

function addObj(obj, key, value) {
  obj[key] = value;
  return obj;
}

matrix[a] = addObj({}, b, addObj({}, c, d));

You can use xp_dirtree

It takes three parameters:

Path of a Root Directory, Depth up to which you want to get files and folders and the last one is for showing folders only or both folders and files.

EXAMPLE: EXEC xp_dirtree 'C:\', 2, 1

In NPM there is a package for this: latinize

It's a very good package to solve this issue.

It would be fine to use query parameters on a POST endpoint, provided they refer to already existing resources.

For example:

POST /user_settings?user_id=4
{
  "use_safe_mode": 1
}

The POST above has a query parameter referring to an existing resource. The body parameter defines the new resource to be created.

(Granted, this may be more of a personal preference than a dogmatic principle.)

You can define the variable in General Declarations and then initialise it in the first event that fires in your environment.

Alternatively, you could create yourself a class with the relevant properties and initialise them in the Initialise method

You could use conditional compilation:

#ifdef WINDOWS
#include <Windows.h>
void beep() {
  Beep(440, 1000);
}
#elif LINUX
#include <stdio.h>
void beep() {
  system("echo -e "\007" >/dev/tty10");
}
#else
#include <stdio.h>
void beep() {
  cout << "\a" << flush;
}
#endif

I was running into a similar error in pywikipediabot. The .decode method is a step in the right direction but for me it didn't work without adding 'ignore':

ignore_encoding = lambda s: s.decode('utf8', 'ignore')

Ignoring encoding errors can lead to data loss or produce incorrect output. But if you just want to get it done and the details aren't very important this can be a good way to move faster.

Given that a WHERE clause did not work, maybe this will:

CREATE TRIGGER 
    [dbo].[SystemParameterInsertUpdate]
ON 
    [dbo].[SystemParameter]
FOR INSERT, UPDATE 
AS
  BEGIN
    SET NOCOUNT ON

      If (SELECT Attribute FROM INSERTED) LIKE 'NoHist_%'
      Begin
          Return
      End

      INSERT INTO SystemParameterHistory 
      (
        Attribute,
        ParameterValue,
        ParameterDescription,
        ChangeDate
      )
    SELECT
      Attribute,
      ParameterValue,
      ParameterDescription,
      ChangeDate
    FROM Inserted AS I
END
