You could do

alert(document.getElementById('table1').rows[0].cells.length)

You need to use ng-disabled directive

<input data-ng-model="userInf.username" 
       class="span12 editEmail" 
       type="text" 
       placeholder="[email protected]" 
       pattern="[^@]+@[^@]+\.[a-zA-Z]{2,6}" 
       required 
       ng-disabled="<expression to disable>" />

you can do this:

bc <<< 'scale=2; 100/3'
33.33

UPDATE 20130926 : you can use:

bc -l <<< '100/3' # saves a few hits
33.33333333333333333333

I know it's an old thread, but I just looked into schemas myself and think the following could be another good candidate for schema usage:

In a Datawarehouse, with data coming from different sources, you can use a different schema for each source, and then e.g. control access based on the schemas. Also avoids the possible naming collisions between the various source, as another poster replied above.

If Android Studio directly opening your project instead of setup window, then just close the windows of all projects. Now you will able to see the startup window. If SDK is missing then it will provide option to download SDK and other required tools.

It works for me.

itoa() function is not defined in ANSI-C, so not implemented by default for some platforms (Reference Link).

s(n)printf() functions are easiest replacement of itoa(). However itoa (integer to ascii) function can be used as a better overall solution of integer to ascii conversion problem.

itoa() is also better than s(n)printf() as performance depending on the implementation. A reduced itoa (support only 10 radix) implementation as an example: Reference Link

Another complete itoa() implementation is below (Reference Link):

#include <stdbool.h> 
#include <string.h>

// A utility function to reverse a string 
char *reverse(char *str)
{
  char *p1, *p2;

  if (! str || ! *str)
        return str;
  for (p1 = str, p2 = str + strlen(str) - 1; p2 > p1; ++p1, --p2)
  {
        *p1 ^= *p2;
        *p2 ^= *p1;
        *p1 ^= *p2;
  }
  return str;
}
// Implementation of itoa() 
char* itoa(int num, char* str, int base) 
{ 
    int i = 0; 
    bool isNegative = false; 
  
    /* Handle 0 explicitely, otherwise empty string is printed for 0 */
    if (num == 0) 
    { 
        str[i++] = '0'; 
        str[i] = '\0'; 
        return str; 
    } 
  
    // In standard itoa(), negative numbers are handled only with  
    // base 10. Otherwise numbers are considered unsigned. 
    if (num < 0 && base == 10) 
    { 
        isNegative = true; 
        num = -num; 
    } 
  
    // Process individual digits 
    while (num != 0) 
    { 
        int rem = num % base; 
        str[i++] = (rem > 9)? (rem-10) + 'a' : rem + '0'; 
        num = num/base; 
    } 
  
    // If number is negative, append '-' 
    if (isNegative) 
        str[i++] = '-'; 
  
    str[i] = '\0'; // Append string terminator 
  
    // Reverse the string 
    reverse(str); 
  
    return str; 
} 

Another complete itoa() implementatiton: Reference Link

An itoa() usage example below (Reference Link):

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
 
int main()
{
    int a=54325;
    char buffer[20];
    itoa(a,buffer,2);   // here 2 means binary
    printf("Binary value = %s\n", buffer);
 
    itoa(a,buffer,10);   // here 10 means decimal
    printf("Decimal value = %s\n", buffer);
 
    itoa(a,buffer,16);   // here 16 means Hexadecimal
    printf("Hexadecimal value = %s\n", buffer);
    return 0;
}

If you want the text within the list items to be centred, try:

ul#menu-utility-navigation {
  width: 100%;
}

ul#menu-utility-navigation li {
  text-align: center;
}

There is an important difference between the two.

Everything not allocated with new behaves much like value types in C# (and people often say that those objects are allocated on the stack, which is probably the most common/obvious case, but not always true. More precisely, objects allocated without using new have automatic storage duration Everything allocated with new is allocated on the heap, and a pointer to it is returned, exactly like reference types in C#.

Anything allocated on the stack has to have a constant size, determined at compile-time (the compiler has to set the stack pointer correctly, or if the object is a member of another class, it has to adjust the size of that other class). That's why arrays in C# are reference types. They have to be, because with reference types, we can decide at runtime how much memory to ask for. And the same applies here. Only arrays with constant size (a size that can be determined at compile-time) can be allocated with automatic storage duration (on the stack). Dynamically sized arrays have to be allocated on the heap, by calling new.

(And that's where any similarity to C# stops)

Now, anything allocated on the stack has "automatic" storage duration (you can actually declare a variable as auto, but this is the default if no other storage type is specified so the keyword isn't really used in practice, but this is where it comes from)

Automatic storage duration means exactly what it sounds like, the duration of the variable is handled automatically. By contrast, anything allocated on the heap has to be manually deleted by you. Here's an example:

void foo() {
  bar b;
  bar* b2 = new bar();
}

This function creates three values worth considering:

On line 1, it declares a variable b of type bar on the stack (automatic duration).

On line 2, it declares a bar pointer b2 on the stack (automatic duration), and calls new, allocating a bar object on the heap. (dynamic duration)

When the function returns, the following will happen: First, b2 goes out of scope (order of destruction is always opposite of order of construction). But b2 is just a pointer, so nothing happens, the memory it occupies is simply freed. And importantly, the memory it points to (the bar instance on the heap) is NOT touched. Only the pointer is freed, because only the pointer had automatic duration. Second, b goes out of scope, so since it has automatic duration, its destructor is called, and the memory is freed.

And the barinstance on the heap? It's probably still there. No one bothered to delete it, so we've leaked memory.

From this example, we can see that anything with automatic duration is guaranteed to have its destructor called when it goes out of scope. That's useful. But anything allocated on the heap lasts as long as we need it to, and can be dynamically sized, as in the case of arrays. That is also useful. We can use that to manage our memory allocations. What if the Foo class allocated some memory on the heap in its constructor, and deleted that memory in its destructor. Then we could get the best of both worlds, safe memory allocations that are guaranteed to be freed again, but without the limitations of forcing everything to be on the stack.

And that is pretty much exactly how most C++ code works. Look at the standard library's std::vector for example. That is typically allocated on the stack, but can be dynamically sized and resized. And it does this by internally allocating memory on the heap as necessary. The user of the class never sees this, so there's no chance of leaking memory, or forgetting to clean up what you allocated.

This principle is called RAII (Resource Acquisition is Initialization), and it can be extended to any resource that must be acquired and released. (network sockets, files, database connections, synchronization locks). All of them can be acquired in the constructor, and released in the destructor, so you're guaranteed that all resources you acquire will get freed again.

As a general rule, never use new/delete directly from your high level code. Always wrap it in a class that can manage the memory for you, and which will ensure it gets freed again. (Yes, there may be exceptions to this rule. In particular, smart pointers require you to call new directly, and pass the pointer to its constructor, which then takes over and ensures delete is called correctly. But this is still a very important rule of thumb)

This is what you need:

 =NOT(ISERROR(MATCH(<cell in col A>,<column B>, 0)))  ## pseudo code

For the first cell of A, this would be:

 =NOT(ISERROR(MATCH(A2,$B$2:$B$5, 0)))

Enter formula (and drag down) as follows:

You will get:

HTML

<div id="replaceMe">i need to be replaced</div>
<div id="iamReplacement">i am replacement</div>

JavaScript

jQuery('#replaceMe').replaceWith(jQuery('#iamReplacement'));

This can be achieved using a Spannable String. You will need to import the following

import android.text.SpannableString; 
import android.text.style.BackgroundColorSpan; 
import android.text.style.StyleSpan;

And then you can change the background of the text using something like the following:

TextView text = (TextView) findViewById(R.id.text_login);
text.setText("");
text.append("Add all your funky text in here");
Spannable sText = (Spannable) text.getText();
sText.setSpan(new BackgroundColorSpan(Color.RED), 1, 4, 0);

Where this will highlight the charecters at pos 1 - 4 with a red color. Hope this helps!

Note that PHP session cookies don't use httponly by default.

To do that:

$sess_name = session_name();
if (session_start()) {
    setcookie($sess_name, session_id(), null, '/', null, null, true);
}

A couple of items of note here:

• You have to call session_name() before session_start()
• This also sets the default path to '/', which is necessary for Opera but which PHP session cookies don't do by default either.

It is better to always check with the library you are using if it supports usage in a non-blocking way.

But if you want a more generic solution, or if there is no other way, you can run anything that blocks in a separated process by using the multprocessing module included in python. Computation will continue:

from multiprocessing import Process
from matplotlib.pyplot import plot, show

def plot_graph(*args):
    for data in args:
        plot(data)
    show()

p = Process(target=plot_graph, args=([1, 2, 3],))
p.start()

print 'yay'
print 'computation continues...'
print 'that rocks.'

print 'Now lets wait for the graph be closed to continue...:'
p.join()

That has the overhead of launching a new process, and is sometimes harder to debug on complex scenarios, so I'd prefer the other solution (using matplotlib's nonblocking API calls)

requests does not handle parsing XML responses, no. XML responses are much more complex in nature than JSON responses, how you'd serialize XML data into Python structures is not nearly as straightforward.

Python comes with built-in XML parsers. I recommend you use the ElementTree API:

import requests
from xml.etree import ElementTree

response = requests.get(url)

tree = ElementTree.fromstring(response.content)

or, if the response is particularly large, use an incremental approach:

    response = requests.get(url, stream=True)
    # if the server sent a Gzip or Deflate compressed response, decompress
    # as we read the raw stream:
    response.raw.decode_content = True

    events = ElementTree.iterparse(response.raw)
    for event, elem in events:
        # do something with `elem`

The external lxml project builds on the same API to give you more features and power still.

var day = value.Date; // a DateTime that will just be whole days
var time = value.TimeOfDay; // a TimeSpan that is the duration into the day

If you work with JDK 1.5 or below the keytool utility will not have the -importkeystore option (see JDK 1.5 keytool documentation) and the solution by MikeD will be available only by transferring the .pfx on a machine with a newer JDK (1.6 or above).

Another option in JDK 1.5 or below (if you have Oracle WebLogic product), is to follow the instructions from this Oracle document: Using PFX and PEM Certificate Formats with Keystores. It describes the conversion into .pem format, how to extract certificates information from this textual format, and import it into .jks format with java utils.ImportPrivateKey utility (this is an utility included with WebLogic product).

Like the answer above but here is using bootstrap 3 names and colours:

/*css to add back colours for badges and make use of the colours*/_x000D_
.badge-default {_x000D_
  background-color: #999999;_x000D_

.badge-danger {_x000D_
  background-color: #d9534f;_x000D_
}

There are a couple of improvements to be made on the existing answers.

Firstly the UIKeyboardWillChangeFrameNotification is probably the best notification as it handles changes that aren't just show/hide but changes due to keyboard changes (language, using 3rd party keyboards etc.) and rotations too (but note comment below indicating the keyboard will hide should also be handled to support hardware keyboard connection).

Secondly the animation parameters can be pulled from the notification to ensure that animations are properly together.

There are probably options to clean up this code a bit more especially if you are comfortable with force unwrapping the dictionary code.

 class MyViewController: UIViewController {

   // This constraint ties an element at zero points from the bottom layout guide
   @IBOutlet var keyboardHeightLayoutConstraint: NSLayoutConstraint?
 
   override func viewDidLoad() {
     super.viewDidLoad()
     NotificationCenter.default.addObserver(self,
       selector: #selector(self.keyboardNotification(notification:)),
       name: UIResponder.keyboardWillChangeFrameNotification,
       object: nil)
   }
 
   deinit {
     NotificationCenter.default.removeObserver(self)
   }
 
   @objc func keyboardNotification(notification: NSNotification) {
     guard let userInfo = notification.userInfo else { return }

     let endFrame = (userInfo[UIResponder.keyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue
     let endFrameY = endFrame?.origin.y ?? 0
     let duration:TimeInterval = (userInfo[UIResponder.keyboardAnimationDurationUserInfoKey] as? NSNumber)?.doubleValue ?? 0
     let animationCurveRawNSN = userInfo[UIResponder.keyboardAnimationCurveUserInfoKey] as? NSNumber
     let animationCurveRaw = animationCurveRawNSN?.uintValue ?? UIView.AnimationOptions.curveEaseInOut.rawValue
     let animationCurve:UIView.AnimationOptions = UIView.AnimationOptions(rawValue: animationCurveRaw)

     if endFrameY >= UIScreen.main.bounds.size.height {
       self.keyboardHeightLayoutConstraint?.constant = 0.0
     } else {
       self.keyboardHeightLayoutConstraint?.constant = endFrame?.size.height ?? 0.0
     }

     UIView.animate(
       withDuration: duration,
       delay: TimeInterval(0),
       options: animationCurve,
       animations: { self.view.layoutIfNeeded() },
       completion: nil)
   }
}

Prior Swift 3.0 :

String(data: yourData, encoding: NSUTF8StringEncoding)

For Swift 4.0:

String(data: yourData, encoding: .utf8)

$( this ).find( 'li.target' ).css("border", "3px double red");

or

$( this ).children( 'li.target' ).css("border", "3px double red");

Use children for immediate descendants, or find for deeper elements.

The solution is

 $conn->set_charset("utf8");

The accepted solution for this will not work if you are planning to compile your scripts using py2exe. If you're planning to do so, this is the functional equivalent:

os.path.dirname(sys.argv[0])

Py2exe does not provide an __file__ variable. For reference: http://www.py2exe.org/index.cgi/Py2exeEnvironment

As Geoff says, what Crockford says is good.

The only exception I follow (and have seen widely used) is to use $varname to indicate a jQuery (or whatever library) object. E.g.

var footer = document.getElementById('footer');

var $footer = $('#footer');

I will provide a classic implementation for a such function. The code works in almost all versions of JavaScript and is somehow optimum.

• It doesn't uses regex, which is hard to maintain
• It doesn't uses new features of JavaScript
• It doesn't uses multiple .split() .join() invocation which require more computer memory

Just pure code:

var text = "Create a function, that will return an array (of string), with the words inside the text";

println(getWords(text));

function getWords(text)
{
    let startWord = -1;
    let ar = [];

    for(let i = 0; i <= text.length; i++)
    {
        let c = i < text.length ? text[i] : " ";

        if (!isSeparator(c) && startWord < 0)
        {
            startWord = i;
        }

        if (isSeparator(c) && startWord >= 0)
        {
            let word = text.substring(startWord, i);
            ar.push(word);

            startWord = -1;
        }
    }

    return ar;
}

function isSeparator(c)
{
    var separators = [" ", "\t", "\n", "\r", ",", ";", ".", "!", "?", "(", ")"];
    return separators.includes(c);
}

Was working on similar task and came across this query, by following few links and working on few exercises for nltk the below code worked for me like magic.

from nltk.tokenize import sent_tokenize 
  
text = "Hello everyone. Welcome to GeeksforGeeks. You are studying NLP article"
sent_tokenize(text) 

output:

['Hello everyone.',
 'Welcome to GeeksforGeeks.',
 'You are studying NLP article']

This may also happen if you have a faulty or accidental equation in your csv file. i.e - One of the cells in your csv file starts with an equals sign (=) (An excel equation) which will, in turn throw an error. If you fix, or remove this equation by getting rid of the equals sign, it should solve the ORA-06502 error.

I find answer. Thanks all but right answer next:

$("#myModal").on("hidden", function () {
  $('#result').html('yes,result');
});

Events here http://bootstrap-ru.com/javascript.php#modals

UPD

For Bootstrap 3.x need use hidden.bs.modal:

$("#myModal").on("hidden.bs.modal", function () {
  $('#result').html('yes,result');
});

Use the function Contains from the strings package.

import (
    "strings"
)
strings.Contains("something", "some") // true

parent() method returns the direct parent element of the selected one. This method only traverse a single level up the DOM tree.

parents() method allows us to search through the ancestors of these elements in the DOM tree. Begin from given selector and move up.

The **.parents()** and **.parent()** methods are almost similar, except that the latter only travels a single level up the DOM tree. Also, **$( "html" ).parent()** method returns a set containing document whereas **$( "html" ).parents()** returns an empty set.

[closest()][3]method returns the first ancestor of the selected element.An ancestor is a parent, grandparent, great-grandparent, and so on.

This method traverse upwards from the current element, all the way up to the document's root element (<html>), to find the first ancestor of DOM elements.

According to docs:

**closest()** method is similar to **parents()**, in that they both traverse up the DOM tree. The differences are as follows:

**closest()**

Begins with the current element
Travels up the DOM tree and returns the first (single) ancestor that matches the passed expression
The returned jQuery object contains zero or one element

**parents()**

Begins with the parent element
Travels up the DOM tree and returns all ancestors that matches the passed expression
The returned jQuery object contains zero or more than one element





 

The methods provide different layers of abstraction.

• $.ajax() gives you full control over the Ajax request. You should use it if the other methods don't fullfil your needs.

• $.get() executes an Ajax GET request. The returned data (which can be any data) will be passed to your callback handler.

• $(selector).load() will execute an Ajax GET request and will set the content of the selected returned data (which should be either text or HTML).

It depends on the situation which method you should use. If you want to do simple stuff, there is no need to bother with $.ajax().

E.g. you won't use $.load(), if the returned data will be JSON which needs to be processed further. Here you would either use $.ajax() or $.get().

I combined a bunch of the previous ideas into one extension method. The benefits here are that you get the correctly typed enumerable back, plus inheritance is handled correctly by OfType().

public static IEnumerable<T> FindAllChildrenByType<T>(this Control control)
{
    IEnumerable<Control> controls = control.Controls.Cast<Control>();
    return controls
        .OfType<T>()
        .Concat<T>(controls.SelectMany<Control, T>(ctrl => FindAllChildrenByType<T>(ctrl)));
}

I was facing the same problem. For my solution, I added br enclosed between 2 brackets < > enclosed in double quotation marks, and preceded and followed by the + sign:

+"<br>"+

Try this in your browser and see, it certainly works in my Internet Explorer.

So this is way late, but I've discovered an answer, in case it becomes useful to anyone who comes across this thread.

Changes in value to hidden elements don't automatically fire the .change() event. So, wherever it is that you're setting that value, you also have to tell jQuery to trigger it.

function setUserID(myValue) {
     $('#userid').val(myValue)
                 .trigger('change');
}

Once that's the case,

$('#userid').change(function(){
      //fire your ajax call  
})

should work as expected.

This is what worked for me:

• Close all Sql Server referencing apps.
• Open Services in Control Panel.
• Find the "SQL Server (SQLEXPRESS)" entry and select properties.
• Stop the service (all Sql Server services).
• Enter "-m" at the Start parameters" fields.
• Start the service (click on Start button on General Tab).
• Open a Command Prompt (right click, Run as administrator if needed).

• Enter the command:

  osql -S localhost\SQLEXPRESS -E

  (or change localhost to whatever your PC is called).

• At the prompt type the following commands:

  CREATE LOGIN my_Login_here WITH PASSWORD = 'my_Password_here'

  go

  sp_addsrvrolemember 'my_Login_here', 'sysadmin'

  go

  quit

• Stop the "SQL Server (SQLEXPRESS)" service.

• Remove the "-m" from the Start parameters field (if still there).

• Start the service.

• In Management Studio, use the login and password you just created. This should give it admin permission.

Arrays inherit equals() from Object and hence compare only returns true if comparing an array against itself.

On the other hand, Arrays.equals compares the elements of the arrays.

This snippet elucidates the difference:

Object o1 = new Object();
Object o2 = new Object();
Object[] a1 = { o1, o2 };
Object[] a2 = { o1, o2 };
System.out.println(a1.equals(a2)); // prints false
System.out.println(Arrays.equals(a1, a2)); // prints true

See also Arrays.equals(). Another static method there may also be of interest: Arrays.deepEquals().

Your check should be:

if (Attachment != null  && Attachment.Length > 0)

First check if the Attachment is null and then lenght, since you are using && that will cause short-circut evaluation

&& Operator (C# Reference)

The conditional-AND operator (&&) performs a logical-AND of its bool operands, but only evaluates its second operand if necessary.

Previously you had the condition like: (Attachment.Length > 0 && Attachment != null), since the first condition is accessing the property Length and if Attachment is null, you end up with the exception, With the modified condition (Attachment != null && Attachment.Length > 0), it will check for null first and only moves further if Attachment is not null.

Using msbuild as pointed out by others worked for me but I needed to do a bit more than just that. First of all, msbuild needs to have access to the compiler. This can be done by running:

"C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\vcvarsall.bat"

Then msbuild was not in my $PATH so I had to run it via its explicit path:

"C:\Windows\Microsoft.NET\Framework64\v4.0.30319\MSBuild.exe" myproj.sln

Lastly, my project was making use of some variables like $(VisualStudioDir). It seems those do not get set by msbuild so I had to set them manually via the /property option:

"C:\Windows\Microsoft.NET\Framework64\v4.0.30319\MSBuild.exe" /property:VisualStudioDir="C:\Users\Administrator\Documents\Visual Studio 2013" myproj.sln

That line then finally allowed me to compile my project.

Bonus: it seems that the command line tools do not require a registration after 30 days of using them like the "free" GUI-based Visual Studio Community edition does. With the Microsoft registration requirement in place, that version is hardly free. Free-as-in-facebook if anything...

You can also configure directly on the file ..sqldeveloper\ide\bin\ide.conf:

Just add the JVM Option:

AddVMOption -Duser.language=en

The file will be like this:

I wrote up a HOWTO for VST development on C++ with Visual Studio awhile back which details the steps necessary to create a basic plugin for the Windows platform (the Mac version of this article is forthcoming). On Windows, a VST plugin is just a normal DLL, but there are a number of "gotchas", and you need to build the plugin using some specific compiler/linker switches or else it won't be recognized by some hosts.

As for the Mac, a VST plugin is just a bundle with the .vst extension, though there are also a few settings which must be configured correctly in order to generate a valid plugin. You can also download a set of Xcode VST plugin project templates I made awhile back which can help you to write a working plugin on that platform.

As for AudioUnits, Apple has provided their own project templates which are included with Xcode. Apple also has very good tutorials and documentation online:

• Audio Unit Programming Guide

I would also highly recommend checking out the Juce Framework, which has excellent support for creating cross-platform VST/AU plugins. If you're going open-source, then Juce is a no-brainer, but you will need to pay licensing fees for it if you plan on releasing your work without source code.

Try using firefox 46.0.1. It best matches with Selenium 2.53

https://ftp.mozilla.org/pub/firefox/releases/46.0.1/win64/en-US/

If this issue occurs, kindly check web.config in below section

Below section gives the version of particular dll used

after checking this section in web.config, open solution explorer and select reference from the project tree as shown . Solution Explorer->Reference

After expanding reference, find the dll which caused the error. Right click on the dll reference and check for version like shown in the image above.

If both config dll version and referenced dll is different you would get this exception. Make sure both are of same version which would help.

JavascriptExecutor jse = (JavascriptExecutor)driver;

Manually formatting the query string is fine for simple situations. But it can become tedious when there are many parameters.

You could write a simple utility function that handles building the query formatting for you.

function formatParams( params ){
  return "?" + Object
        .keys(params)
        .map(function(key){
          return key+"="+encodeURIComponent(params[key])
        })
        .join("&")
}

And you would use it this way to build a request.

var endpoint = "https://api.example.com/endpoint"
var params = {
  a: 1, 
  b: 2,
  c: 3
}

var url = endpoint + formatParams(params)
//=> "https://api.example.com/endpoint?a=1&b=2&c=3"

There are many utility functions available for manipulating URL's. If you have JQuery in your project you could give http://api.jquery.com/jquery.param/ a try.

It is similar to the above example function, but handles recursively serializing nested objects and arrays.

if(Test-Path "C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS") { #Sql Server 2012
    Import-Module SqlPs -DisableNameChecking
    C: # Switch back from SqlServer
} else { #Sql Server 2008
    Add-PSSnapin SqlServerCmdletSnapin100 # here live Invoke-SqlCmd
}

Invoke-Sqlcmd -InputFile "MySqlScript.sql" -ServerInstance "Database name" -ErrorAction 'Stop' -Verbose -QueryTimeout 1800 # 30min

One already exists. If you cannot get over the "Move" syntax of the System.IO namespace. There is a static class FileSystem within the Microsoft.VisualBasic.FileIO namespace that has both a RenameDirectory and RenameFile already within it.

As mentioned by SLaks, this is just a wrapper for Directory.Move and File.Move.

Here you can check for couple of things.

1. Date formats you are using correctly. You can provide more than one format for DateTime.TryParseExact. Check the complete list of formats, available here.

2. CultureInfo.InvariantCulture which is more likely add problem. So instead of passing a NULL value or setting it to CultureInfo provider = new CultureInfo("en-US"), you may write it like. .

   if (!DateTime.TryParseExact(txtStartDate.Text, formats, 
                   System.Globalization.CultureInfo.InvariantCulture,
                   System.Globalization.DateTimeStyles.None, out startDate))
   {
       //your condition fail code goes here
       return false;
   }
   else
   {
       //success code
   }
   

You seem to just have begun using mysql.

Simple answer: for now use

mysql -u root -p password

Password is usually root by default. You may use other usernames if you have created other user using create user in mysql. For details use "help, help manage accounts, help create users" etc. If you dont want your password to be shown in open just press return key after "-p" and you will be prompted for password next. Hope this resolves the issue.

I know this is an old question, but I faced the same problem recently in Laravel 7 application. To make renaming columns work I used a tip from this answer where instead of composer require doctrine/dbal I have issued composer require doctrine/dbal:^2.12.1 because the latest version of doctrine/dbal still throws an error.

Just keep in mind that if you already use a higher version, this answer might not be appropriate for you.

Following are eight ways to find the Uptime in Windows OS.

1: By using the Task Manager

In Windows Vista and Windows Server 2008, the Task Manager has been beefed up to show additional information about the system. One of these pieces of info is the server’s running time.

1. Right-click on the Taskbar, and click Task Manager. You can also click CTRL+SHIFT+ESC to get to the Task Manager.
2. In Task Manager, select the Performance tab.

3. The current system uptime is shown under System or Performance ⇒ CPU for Win 8/10.

   

2: By using the System Information Utility

The systeminfo command line utility checks and displays various system statistics such as installation date, installed hotfixes and more. Open a Command Prompt and type the following command:

systeminfo

You can also narrow down the results to just the line you need:

systeminfo | find "System Boot Time:"

3: By using the Uptime Utility

Microsoft have published a tool called Uptime.exe. It is a simple command line tool that analyses the computer's reliability and availability information. It can work locally or remotely. In its simple form, the tool will display the current system uptime. An advanced option allows you to access more detailed information such as shutdown, reboots, operating system crashes, and Service Pack installation.

Read the following KB for more info and for the download links:

• MSKB232243: Uptime.exe Tool Allows You to Estimate Server Availability with Windows NT 4.0 SP4 or Higher.

To use it, follow these steps:

1. Download uptime.exe from the above link, and save it to a folder, preferably in one that's in the system's path (such as SYSTEM32).
2. Open an elevated Command Prompt window. To open an elevated Command Prompt, click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator. You can also type CMD in the search box of the Start menu, and when you see the Command Prompt icon click on it to select it, hold CTRL+SHIFT and press ENTER.
3. Navigate to where you've placed the uptime.exe utility.
4. Run the uptime.exe utility. You can add a /? to the command in order to get more options.

It does not offer many command line parameters:

C:\uptimefromcodeplex\> uptime /?
usage: Uptime [-V]
    -V   display version

C:\uptimefromcodeplex\> uptime -V
version 1.1.0

3.1: By using the old Uptime Utility

There is an older version of the "uptime.exe" utility. This has the advantage of NOT needing .NET. (It also has a lot more features beyond simple uptime.)

Download link: Windows NT 4.0 Server Uptime Tool (uptime.exe) (final x86)

C:\uptimev100download>uptime.exe /?

UPTIME, Version 1.00
(C) Copyright 1999, Microsoft Corporation

Uptime [server] [/s ] [/a] [/d:mm/dd/yyyy | /p:n] [/heartbeat] [/? | /help]
        server          Name or IP address of remote server to process.
        /s              Display key system events and statistics.
        /a              Display application failure events (assumes /s).
        /d:             Only calculate for events after mm/dd/yyyy.
        /p:             Only calculate for events in the previous n days.
        /heartbeat      Turn on/off the system's heartbeat
        /?              Basic usage.
        /help           Additional usage information.

4: By using the NET STATISTICS Utility

Another easy method, if you can remember it, is to use the approximate information found in the statistics displayed by the NET STATISTICS command. Open a Command Prompt and type the following command:

net statistics workstation

The statistics should tell you how long it’s been running, although in some cases this information is not as accurate as other methods.

5: By Using the Event Viewer

Probably the most accurate of them all, but it does require some clicking. It does not display an exact day or hour count since the last reboot, but it will display important information regarding why the computer was rebooted and when it did so. We need to look at Event ID 6005, which is an event that tells us that the computer has just finished booting, but you should be aware of the fact that there are virtually hundreds if not thousands of other event types that you could potentially learn from.

Note: BTW, the 6006 Event ID is what tells us when the server has gone down, so if there’s much time difference between the 6006 and 6005 events, the server was down for a long time.

Note: You can also open the Event Viewer by typing eventvwr.msc in the Run command, and you might as well use the shortcut found in the Administrative tools folder.

2. Click on Event Viewer (Local) in the left navigation pane.
3. In the middle pane, click on the Information event type, and scroll down till you see Event ID 6005. Double-click the 6005 Event ID, or right-click it and select View All Instances of This Event.
4. A list of all instances of the 6005 Event ID will be displayed. You can examine this list, look at the dates and times of each reboot event, and so on.
5. Open Server Manager tool by right-clicking the Computer icon on the start menu (or on the Desktop if you have it enabled) and select Manage. Navigate to the Event Viewer.

5.1: Eventlog via PowerShell

Get-WinEvent -ProviderName eventlog | Where-Object {$_.Id -eq 6005 -or $_.Id -eq 6006}

6: Programmatically, by using GetTickCount64

GetTickCount64 retrieves the number of milliseconds that have elapsed since the system was started.

7: By using WMI

wmic os get lastbootuptime

8: The new uptime.exe for Windows XP and up

Like the tool from Microsoft, but compatible with all operating systems up to and including Windows 10 and Windows Server 2016, this uptime utility does not require an elevated command prompt and offers an option to show the uptime in both DD:HH:MM:SS and in human-readable formats (when executed with the -h command-line parameter).

Additionally, this version of uptime.exe will run and show the system uptime even when launched normally from within an explorer.exe session (i.e. not via the command line) and pause for the uptime to be read:

and when executed as uptime -h:

public String replace(String input, Map<String, String> pairs) {
  // Reverse lexic-order of keys is good enough for most cases,
  // as it puts longer words before their prefixes ("tool" before "too").
  // However, there are corner cases, which this algorithm doesn't handle
  // no matter what order of keys you choose, eg. it fails to match "edit"
  // before "bed" in "..bedit.." because "bed" appears first in the input,
  // but "edit" may be the desired longer match. Depends which you prefer.
  final Map<String, String> sorted = 
      new TreeMap<String, String>(Collections.reverseOrder());
  sorted.putAll(pairs);
  final String[] keys = sorted.keySet().toArray(new String[sorted.size()]);
  final String[] vals = sorted.values().toArray(new String[sorted.size()]);
  final int lo = 0, hi = input.length();
  final StringBuilder result = new StringBuilder();
  int s = lo;
  for (int i = s; i < hi; i++) {
    for (int p = 0; p < keys.length; p++) {
      if (input.regionMatches(i, keys[p], 0, keys[p].length())) {
        /* TODO: check for "edit", if this is "bed" in "..bedit.." case,
         * i.e. look ahead for all prioritized/longer keys starting within
         * the current match region; iff found, then ignore match ("bed")
         * and continue search (find "edit" later), else handle match. */
        // if (better-match-overlaps-right-ahead)
        //   continue;
        result.append(input, s, i).append(vals[p]);
        i += keys[p].length();
        s = i--;
      }
    }
  }
  if (s == lo) // no matches? no changes!
    return input;
  return result.append(input, s, hi).toString();
}

if (User.Identity.IsAuthenticated)
{
    Page.Title = "Home page for " + User.Identity.Name;
}
else
{
    Page.Title = "Home page for guest user.";
}

There are two competing concerns: with less training data, your parameter estimates have greater variance. With less testing data, your performance statistic will have greater variance. Broadly speaking you should be concerned with dividing data such that neither variance is too high, which is more to do with the absolute number of instances in each category rather than the percentage.

If you have a total of 100 instances, you're probably stuck with cross validation as no single split is going to give you satisfactory variance in your estimates. If you have 100,000 instances, it doesn't really matter whether you choose an 80:20 split or a 90:10 split (indeed you may choose to use less training data if your method is particularly computationally intensive).

Assuming you have enough data to do proper held-out test data (rather than cross-validation), the following is an instructive way to get a handle on variances:

1. Split your data into training and testing (80/20 is indeed a good starting point)
2. Split the training data into training and validation (again, 80/20 is a fair split).
3. Subsample random selections of your training data, train the classifier with this, and record the performance on the validation set
4. Try a series of runs with different amounts of training data: randomly sample 20% of it, say, 10 times and observe performance on the validation data, then do the same with 40%, 60%, 80%. You should see both greater performance with more data, but also lower variance across the different random samples
5. To get a handle on variance due to the size of test data, perform the same procedure in reverse. Train on all of your training data, then randomly sample a percentage of your validation data a number of times, and observe performance. You should now find that the mean performance on small samples of your validation data is roughly the same as the performance on all the validation data, but the variance is much higher with smaller numbers of test samples

for a solution that uses ncurses with working code and initialization of ncurses see getchar() returns the same value (27) for up and down arrow keys

Converting to double can be done by casting an int to a double:

You can convert an int to a double by using this mechnism like so:

int i = 3; // i is 3
double d = (double) i; // d = 3.0

Alternative (using Java's automatic type recognition):

double d = 1.0 * i; // d = 3.0

Implementing this in your code would be something like:

double firstSolution = ((double)(b1 * a22 - b2 * a12) / (double)(a11 * a22 - a12 * a21));
double secondSolution = ((double)(b2 * a11 - b1 * a21) / (double)(a11 * a22 - a12 * a21));

Alternatively you can use a hard-parameter of type double (1.0) to have java to the work for you, like so:

double firstSolution = ((1.0 * (b1 * a22 - b2 * a12)) / (1.0 * (a11 * a22 - a12 * a21)));
double secondSolution = ((1.0 * (b2 * a11 - b1 * a21)) / (1.0 * (a11 * a22 - a12 * a21)));

Good luck.

Another reason of this problem can be column type of "payload" sessions table. If you have huge data on session, a text column wouldn't be enough. You will need MEDIUMTEXT or even LONGTEXT.

No, LINQ doesn't support a manner of mass updating. The only shorter way would be to use a ForEach extension method - Why there is no ForEach extension method on IEnumerable?

For those of you who share my weird fondness of manually editing config files, adding (or modifying) the following would also do the trick.

.git/config (personal config)

[submodule "cookbooks/apt"]
    url = https://github.com/opscode-cookbooks/apt

.gitmodules (committed shared config)

[submodule "cookbooks/apt"]
    path = cookbooks/apt
    url = https://github.com/opscode-cookbooks/apt

See this as well - difference between .gitmodules and specifying submodules in .git/config?

here is the playground example with pointers in it. https://play.golang.org/p/uNpTKeCt0sH

package main

import (
    "fmt"
)

type t struct {
    a int
    b string
}

func (tt *t) String() string{
    return fmt.Sprintf("[%d %s]", tt.a, tt.b)
}

func remove(slice []*t, i int) []*t {
  copy(slice[i:], slice[i+1:])
  return slice[:len(slice)-1]
}

func main() {
    a := []*t{&t{1, "a"}, &t{2, "b"}, &t{3, "c"}, &t{4, "d"}, &t{5, "e"}, &t{6, "f"}}
    k := a[3]
    a = remove(a, 3)
    fmt.Printf("%v  ||  %v", a, k)
}

You had selected the time format wrong

<?php 
date_default_timezone_set('GMT');

echo date("Y-m-d,h:m:s");
?>

Just declare a default value for a field:

CREATE TABLE MyTable(
    ID INTEGER PRIMARY KEY,
    Name TEXT,
    Other STUFF,
    Timestamp DATETIME DEFAULT CURRENT_TIMESTAMP
);

However, if your INSERT command explicitly sets this field to NULL, it will be set to NULL.

There is a method update on BaseQuery object in SQLAlchemy, which is returned by filter_by.

num_rows_updated = User.query.filter_by(username='admin').update(dict(email='[email protected]')))
db.session.commit()

The advantage of using update over changing the entity comes when there are many objects to be updated.

If you want to give add_user permission to all the admins,

rows_changed = User.query.filter_by(role='admin').update(dict(permission='add_user'))
db.session.commit()

Notice that filter_by takes keyword arguments (use only one =) as opposed to filter which takes an expression.

If you don't have an index assigned to the data and you are not sure what the spacing is, you can use to let pandas assign an index and look for multiple spaces.

df = pd.read_csv('filename.txt', delimiter= '\s+', index_col=False)

Could append a new stylesheet to head within $routeProvider. For simplicity am using a string but could create new link element also, or create a service for stylesheets

/* check if already exists first - note ID used on link element*/
/* could also track within scope object*/
if( !angular.element('link#myViewName').length){
    angular.element('head').append('<link id="myViewName" href="myViewName.css" rel="stylesheet">');
}

Biggest benefit of prelaoding in page is any background images will already exist, and less lieklyhood of FOUC

Images have display: inline by default.
You might want to put the image inside the paragraph.

Add the following attribute the action (post) in the controller that you want to allow HTML for:

[ValidateInput(false)] 

Edit: As per Charlino comments:

In your web.config set the validation mode used. See MSDN:

<httpRuntime requestValidationMode="2.0" />

Edit Sept 2014: As per sprinter252 comments:

You should now use the [AllowHtml] attribute. See below from MSDN:

For ASP.NET MVC 3 applications, when you need to post HTML back to your model, don’t use ValidateInput(false) to turn off Request Validation. Simply add [AllowHtml] to your model property, like so:

public class BlogEntry {
    public int UserId {get;set;}
    [AllowHtml] 
    public string BlogText {get;set;}
 }

Here is the step by step process to include php code in html file ( Tested )

If PHP is working there is only one step left to use PHP scripts in files with *.html or *.htm extensions as well. The magic word is ".htaccess". Please see the Wikipedia definition of .htaccess to learn more about it. According to Wikipedia it is "a directory-level configuration file that allows for decentralized management of web server configuration."

You can probably use such a .htaccess configuration file for your purpose. In our case you want the webserver to parse HTML files like PHP files.

First, create a blank text file and name it ".htaccess". You might ask yourself why the file name starts with a dot. On Unix-like systems this means it is a dot-file is a hidden file. (Note: If your operating system does not allow file names starting with a dot just name the file "xyz.htaccess" temporarily. As soon as you have uploaded it to your webserver in a later step you can rename the file online to ".htaccess") Next, open the file with a simple text editor like the "Editor" in MS Windows. Paste the following line into the file: AddType application/x-httpd-php .html .htm If this does not work, please remove the line above from your file and paste this alternative line into it, for PHP5: AddType application/x-httpd-php5 .html .htm Now upload the .htaccess file to the root directory of your webserver. Make sure that the name of the file is ".htaccess". Your webserver should now parse *.htm and *.html files like PHP files.

You can try if it works by creating a HTML-File like the following. Name it "php-in-html-test.htm", paste the following code into it and upload it to the root directory of your webserver:

    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
     <HTML>
 <HEAD>
 <TITLE>Use PHP in HTML files</TITLE>
 </HEAD>

   <BODY>
    <h1>
    <?php echo "It works!"; ?>
    </h1>
  </BODY>
 </HTML>

Try to open the file in your browser by typing in: http://www.your-domain.com/php-in-html-test.htm (once again, please replace your-domain.com by your own domain...) If your browser shows the phrase "It works!" everything works fine and you can use PHP in .*html and *.htm files from now on. However, if not, please try to use the alternative line in the .htaccess file as we showed above. If is still does not work please contact your hosting provider.

I had the same issue when installing opencv 2.4.13 on Anaconda3 (Python 3.6)... I managed to fix this issue by reverting to Anaconda2 (Python 2.7)

From command line -

Hadoop fs -copyFromLocal

Hadoop fs -copyToLocal

Or you also use spark FileSystem library to get or put hdfs file.

Hope this is helpful.

The right way would be

[[[0 for _ in range(n)] for _ in range(n)] for _ in range(n)]

(What you're trying to do should be written like (for NxNxN)

[[[0]*n]*n]*n

but that is not correct, see @Adaman comment why).

var table = document.getElementById("someTableID"); 
var totalRows = document.getElementById("someTableID").rows.length;
var totalCol = 3; // enter the number of columns in the table minus 1 (first column is 0 not 1)
//To display all values
for (var x = 0; x <= totalRows; x++)
  {
  for (var y = 0; y <= totalCol; y++)
    {
    alert(table.rows[x].cells[y].innerHTML;
    }
  }
//To display a single cell value enter in the row number and column number under rows and cells below:
var firstCell = table.rows[0].cells[0].innerHTML;
alert(firstCell);
//Note:  if you use <th> this will be row 0, so your data will start at row 1 col 0

Use:

((Long) userService.getAttendanceList(currentUser)).intValue();

instead.

The .intValue() method is defined in class Number, which Long extends.

I'd make a third suggestion, Google Closure Compiler (and also the Closure Linter). You can try it out online here.

The Closure Compiler is a tool for making JavaScript download and run faster. It is a true compiler for JavaScript. Instead of compiling from a source language to machine code, it compiles from JavaScript to better JavaScript. It parses your JavaScript, analyzes it, removes dead code and rewrites and minimizes what's left. It also checks syntax, variable references, and types, and warns about common JavaScript pitfalls.

 Intent intent = new Intent(activity1.this, activity2.class);
 intent.putExtra("message", message);
 startActivity(intent);

In activity2, in onCreate(), you can get the String message by retrieving a Bundle (which contains all the messages sent by the calling activity) and call getString() on it :

  Bundle bundle = getIntent().getExtras();
  String message = bundle.getString("message");

By default, it begins by processing the first target that does not begin with a . aka the default goal; to do that, it may have to process other targets - specifically, ones the first target depends on.

The GNU Make Manual covers all this stuff, and is a surprisingly easy and informative read.

Add a literal space, or a tab:

public void displayCustomerInfo() {
    System.out.println(Name + " " + Income);

    // or a tab
    System.out.println(Name + "\t" + Income);
}

    private void BindDataBInfo()
    {
        System.Web.HttpBrowserCapabilities browser = Request.Browser;
        Literal1.Text = "<table border=\"1\" cellspacing=\"3\" cellpadding=\"2\">";
        foreach (string key in browser.Capabilities.Keys)
        {
            Literal1.Text += "<tr><td>" + key + "</td><td>" + browser[key] + "</tr>";
        }
        Literal1.Text += "</table>";
        browser = null;
    }

That's too complex to set in the definition. You can set the definition to null though, and then in the constructor, check it, and if it has not been changed - set it:

private static $dates = null;
public function __construct()
{
    if (is_null(self::$dates)) {  // OR if (!is_array(self::$date))
         self::$dates = array( /* .... */);
    }
}

You can use the ansible.cfg file, it should look like this (There are other parameters which you might want to include):

[defaults]
inventory = <PATH TO INVENTORY FILE>
remote_user = <YOUR USER>
private_key_file =  <PATH TO KEY_FILE>

Hope this saves you some typing

git reset --hard origin/master

to reset it to whatever the origin was at.

This was posted by @bdonlan in the comments. I added this answer for people who don't read comments.

Static member variables must be declared in the class and then defined outside of it!

There's no workaround, just put their actual definition in a source file.

From your description it smells like you're not using static variables the right way. If they never change you should use constant variable instead, but your description is too generic to say something more.

Static member variables always hold the same value for any instance of your class: if you change a static variable of one object, it will change also for all the other objects (and in fact you can also access them without an instance of the class - ie: an object).

1· Do I need these DLL's?

It depends since Dependency Walker is a little bit out of date and may report the wrong dependency.

2. Where can I get them?

most dlls can be found at https://www.dll-files.com

I believe they are supposed to located in C:\Windows\System32\Wer.dll and C:\Program Files\Internet Explorer\Ieshims.dll

For me leshims.dll can be placed at C:\Windows\System32\. Context: windows 7 64bit.

You can try ironJS, looks promising although it is in heavy development. https://github.com/fholm/IronJS

Let's start with the need for scaling that is increasing resources so that your system can now handle more requests than it earlier could.

When you realise your system is getting slow and is unable to handle the current number of requests, you need to scale the system.

This provides you with two options. Either you increase the resources in the server which you are using currently, i.e, increase the amount of RAM, CPU, GPU and other resources. This is known as vertical scaling.

Vertical scaling is typically costly. It does not make the system fault tolerant, i.e if you are scaling application running with single server, if that server goes down, your system will go down. Also the amount of threads remains the same in vertical scaling. Vertical scaling may require your system to go down for a moment when process takes place. Increasing resources on a server requires a restart and put your system down.

Another solution to this problem is increasing the amount of servers present in the system. This solution is highly used in the tech industry. This will eventually decrease the request per second rate in each server. If you need to scale the system, just add another server, and you are done. You would not be required to restart the system. Number of threads in each system decreases leading to high throughput. To segregate the requests, equally to each of the application server, you need to add load balancer which would act as reverse proxy to the web servers. This whole system can be called as a single cluster. Your system may contain a large number of requests which would require more amount of clusters like this.

Hope you get the whole concept of introducing scaling to the system.

Perhaps use tikz.

I've found that in 17.09 there is a simplest way to do it within docker container:

$ cat /proc/self/cgroup | head -n 1 | cut -d '/' -f3
4de1c09d3f1979147cd5672571b69abec03d606afcc7bdc54ddb2b69dec3861c

Or like it has already been told, a shorter version with

$ cat /etc/hostname
4de1c09d3f19

Or simply:

$ hostname
4de1c09d3f19

You can simply use

int numberOfLetters = yourWord.Length;

or to be cool and trendy, use LINQ like this :

int numberOfLetters = yourWord.ToCharArray().Count();

and if you hate both Properties and LINQ, you can go old school with a loop :

int numberOfLetters = 0;
foreach (char letter in yourWord)
{
    numberOfLetters++;
}

I see some errors in your code.
Your probably meant the mathematical term

90 <= angle <= 180, meaning angle in range 90-180.

if (angle >= 90 && angle <= 180) {

// do action
}

Using standard KeyboardEvent

As Joe comment it, KeyboardEvent is now the standard.

Same example to fire an enter (keyCode 13):

const ke = new KeyboardEvent('keydown', {
    bubbles: true, cancelable: true, keyCode: 13
});
document.body.dispatchEvent(ke);

You can use this page help you to find the right keyboard event.

Outdated answer:

• initKeyboardEvent for IE9+, Chrome and Safari
• initKeyEvent for Firefox

You can do something like (here for Firefox)

var ev = document.createEvent('KeyboardEvent');
// Send key '13' (= enter)
ev.initKeyEvent(
    'keydown', true, true, window, false, false, false, false, 13, 0);
document.body.dispatchEvent(ev);

Choose Database | Set Datasource Location... Select the database node (yellow-ish cylinder) of the current connection, then select the database node of the desired connection (you may need to authenticate), then click Update.

You will need to do this for the 'Subreports' nodes as well.

FYI, you can also do individual tables by selecting each individually, then choosing Update.

import sys
if not sys.warnoptions:
    import warnings
    warnings.simplefilter("ignore")

Change ignore to default when working on the file or adding new functionality to re-enable warnings.

Felipsmartins is correct.

It is worth mentioning that it is because you cannot really use the -d/--data option if this is not a POST request. But this is still possible if you use the -G option.

Which means you can do this:

curl -X DELETE -G 'http://localhost:5000/locations' -d 'id=3'

Here it is a bit silly but when you are on the command line and you have a lot of parameters, it is a lot tidier.

I am saying this because cURL commands are usually quite long, so it is worth making it on more than one line escaping the line breaks.

curl -X DELETE -G \
'http://localhost:5000/locations' \
-d id=3 \
-d name=Mario \
-d surname=Bros

This is obviously a lot more comfortable if you use zsh. I mean when you need to re-edit the previous command because zsh lets you go line by line. (just saying)

Hope it helps.

Inline Stored procedure we using as per our need. Example like different Same parameter with different values we have to use in queries..

Create Proc SP1
(
 @ID int,
 @Name varchar(40)
 -- etc parameter list, If you don't have any parameter then no need to pass.
 )

  AS
  BEGIN

  -- Here we have some opereations

 -- If there is any Error Before Executing SP2 then SP will stop executing.

  Exec SP2 @ID,@Name,@SomeID OUTPUT 

 -- ,etc some other parameter also we can use OutPut parameters like 

 -- @SomeID is useful for some other operations for condition checking insertion etc.

 -- If you have any Error in you SP2 then also it will stop executing.

 -- If you want to do any other operation after executing SP2 that we can do here.

The basic difference between Web Services and Web APIs

Web Service:

1) It is a SOAP-based service and returns data as XML.

2) It only supports the HTTP protocol.

3) It is not open source but can be used by any client that understands XML.

5) It requires a SOAP protocol to receive and send data over the network, so it is not a light-weight architecture.

Web API:

1) A Web API is an HTTP based service and returns JSON or XML data by default.

2) It supports the HTTP protocol.

3) It can be hosted within an application or IIS.

4) It is open source and it can be used by any client that understands JSON or XML.

5) It has light-weight architecture and good for devices which have limited bandwidth, like mobile devices.

You might create a View selecting the column names required by your insert statement, add an INSTEAD OF INSERT Trigger, and insert into this view.

Your problem is not that the div is not at 100% height, but that the container around it is not.This will help in the browser I suspect you are using:

html,body { height:100%; }

You may need to adjust padding and margins as well, but this will get you 90% of the way there.If you need to make it work with all browsers you will have to mess around with it a bit.

This site has some excellent examples:

http://www.brunildo.org/test/html_body_0.html

I investigated this a bit since I have the same Issue. What I did not like about the previous solutions was, that the autocomplete already fired the AutocompleteService to show the predictions. Therefore, the predictions should be somewhere and should not be loaded again.

I found out that the predictions of place inkl. place_id is stored in

Autocomplete.gm_accessors_.place.Kc.l

and you will be able to get a lot of data from the records [0].data. Imho, it's faster and better to get the location by using the place_id instead of address data. This very strange object selection appears not very good to me, tho.

Do you know, if there is a better way to retrieve the first prediction from the autocomplete?

Happens when php extensions are not being used by default. In your php.ini file, change
;extension=php_mysql.dll
to
extension=php_mysql.dll.

**If this error logs, then add path to this dll file, eg
extension=C:\Php\php-???-nts-Win32-VC11-x86\ext\php_mysql.dll

Do same for php_mysqli.dll and php_pdo_mysql.dll. Save and run your code again.

Add comments for two different columns of the EMPLOYEE table :

COMMENT ON EMPLOYEE
     (WORKDEPT IS 'see DEPARTMENT table for names',
     EDLEVEL IS 'highest grade level passed in school' )

Without using any external dependency or library:

$options = array(
  'http' => array(
    'method'  => 'POST',
    'content' => json_encode( $data ),
    'header'=>  "Content-Type: application/json\r\n" .
                "Accept: application/json\r\n"
    )
);

$context  = stream_context_create( $options );
$result = file_get_contents( $url, false, $context );
$response = json_decode( $result );

$response is an object. Properties can be accessed as usual, e.g. $response->...

where $data is the array contaning your data:

$data = array(
  'userID'      => 'a7664093-502e-4d2b-bf30-25a2b26d6021',
  'itemKind'    => 0,
  'value'       => 1,
  'description' => 'Boa saudaÁ„o.',
  'itemID'      => '03e76d0a-8bab-11e0-8250-000c29b481aa'
);

Warning: this won't work if the allow_url_fopen setting is set to Off in the php.ini.

You are most often better of using the most general usable type, in this case the IList or even better the IEnumerable interface, so that you can switch the implementation conveniently at a later time.

However, in .NET 2.0, there is an annoying thing - IList does not have a Sort() method. You can use a supplied adapter instead:

ArrayList.Adapter(list).Sort()

In my case, I found a reference to an old domain account password in applicationHost.config under Virtual Directory defaults.

I'd take the library at http://json.org/java/, and modify the equals method of JSONObject and JSONArray to do a deep equality test. To make sure that it works regradless of the order of the children, all you need to do is replace the inner map with a TreeMap, or use something like Collections.sort().

Add your li to a class, and do $(".myclass").hide(); at the start to hide it instead of the visibility style attribute.

As far as I know, jquery uses the display style attribute to show/hide elements instead of visibility (may be wrong on that one, in either case the above is worth trying)

To disable specific rules for file(s) inside folder(s), you need to use the "overrides" key of your .eslintrc config file.

For example, if you want to remove the following rules:

1. no-use-before-define
2. max-lines-per-function

For all files inside the following main directory:

/spec

You can add this to your .eslintrc file...

"overrides": [
  {
    "files": ["spec/**/*.js"],
    "rules": {
      "no-use-before-define": ["off"],
      "max-lines-per-function": ["off"]
    }
  }
]

Note that I used ** inside the spec/**/*.js glob, which means I am looking recursively for all subfolders inside the folder called spec and selecting all files that ends with js in order to remove the desired rules from them.

The solution no one tells is that in Mysql v5.5 and later InnoDB is the default storage engine which does not have this problem but in many cases like mine there are some old mysql ini configuration files which are using old MYISAM storage engine like below.

default-storage-engine=MYISAM

which is creating all these problems and the solution is to change default-storage-engine to InnoDB in the Mysql's ini configuration file once and for all instead of doing temporary hacks.

default-storage-engine=InnoDB

And if you are on MySql v5.5 or later then InnoDB is the default engine so you do not need to set it explicitly like above, just remove the default-storage-engine=MYISAM if it exist from your ini file and you are good to go.

For python version 2.x you can simply use

I actually had ran into this issue the other day and it worked wonders. =)

The accepted solution looks good, but there is one case it cannot handle:

The "onchange" event will not be triggered when the same option is reselected. So, I came up with the following improvement:

HTML

<select id="sampleSelect" >
  <option value="Home.php">Home</option>
  <option value="Contact.php">Contact</option>
  <option value="Sitemap.php">Sitemap</option>
</select>

jQuery

$("select").click(function() {
  var open = $(this).data("isopen");
  if(open) {
    window.location.href = $(this).val()
  }
  //set isopen to opposite so next time when use clicked select box
  //it wont trigger this event
  $(this).data("isopen", !open);
});

Hmmm ...

If you can connect with the username and password in pgAdminIII but you can't connect with psql then those two programs are probably connecting to the database differently.

[If you're connecting to different databases, first try connecting to the same database. See below.]

From PostgreSQL: Documentation: 9.3: psql:

If you omit the host name, psql will connect via a Unix-domain socket to a server on the local host, or via TCP/IP to localhost on machines that don't have Unix-domain sockets.

If you're not running something like psql ... -h host_name ..., and you're running Ubuntu, psql should be connecting via a Unix-domain socket, so PostgreSQL probably isn't configured to allow one of the password authentication methods for the postgres user.

You can test this by running:

sudo -u postgres psql

If the above works, your server is probably configured to use peer authentication for local connections by the postgres user, i.e. asking the OS for your user name to confirm that you're postgres.

So It's Probably Your pg_hba.conf File

The full path of the file will be something like /etc/postgresql/9.3/main/pg_hba.conf. You can view it by, e.g. sudo cat /etc/postgresql/9.3/main/pg_hba.conf | more.

If you're omitting the host name in your psql command, you should be able to connect if you add the following entry to your pg_hba.conf file:

# Connection type   Database   User       IP addresses   Method
local               all        postgres                  md5

[Commented lines in the pg_hba.conf file start with #.]

If you are including the host name in your psql command, add this entry instead:

# Connection type   Database   User       IP addresses   Method
host                all        postgres   127.0.0.1/32   md5

You need to put the entry before any other entries are matched for your connection via psql. If in doubt about where to put it, just put it before the first un-commented line.

More about pg_hba.conf

From PostgreSQL: Documentation: 9.3: The pg_hba.conf File [bold emphasis mine]:

The first record with a matching connection type, client address, requested database, and user name is used to perform authentication. There is no "fall-through" or "backup": if one record is chosen and the authentication fails, subsequent records are not considered. If no record matches, access is denied.

Note that records are not matched on authentication method. So, if your pg_hba.conf file contains the following entry:

# Connection type   Database   User       IP addresses   Method
local               all        postgres                  peer

Then you won't be able to connect via:

psql -u postgres

Unless one of these entries is in your pg_hba.conf file above the former entry:

# Connection type   Database   User       IP addresses   Method
local               all        postgres                  md5
local               all        postgres                  password   # Unencrypted!
local               all        all                       md5
local               all        all                       password   # Unencrypted!

50% of C++ programmers like to set their pointers to null after a delete:

template<typename T>    
void moronic_delete(T*& p)
{
    delete p;
    p = nullptr;
}

Without the reference, you would only be changing a local copy of the pointer, not affecting the caller.

Just set your width to auto:

#myWorkContent{
    width: auto;
    height:210px;
    border: 13px solid #bed5cd;
    overflow-x: scroll;
    overflow-y: hidden;
    white-space: nowrap;
}

This way your div can be as wide as possible, so you can add as many kitty images as possible ;3

Your div's width will expand based on the child elements it contains.

Note

The below answer is not applicable to requests v0.13.0+. The asynchronous functionality was moved to grequests after this question was written. However, you could just replace requests with grequests below and it should work.

I've left this answer as is to reflect the original question which was about using requests < v0.13.0.

To do multiple tasks with async.map asynchronously you have to:

1. Define a function for what you want to do with each object (your task)
2. Add that function as an event hook in your request
3. Call async.map on a list of all the requests / actions

Example:

from requests import async
# If using requests > v0.13.0, use
# from grequests import async

urls = [
    'http://python-requests.org',
    'http://httpbin.org',
    'http://python-guide.org',
    'http://kennethreitz.com'
]

# A simple task to do to each response object
def do_something(response):
    print response.url

# A list to hold our things to do via async
async_list = []

for u in urls:
    # The "hooks = {..." part is where you define what you want to do
    # 
    # Note the lack of parentheses following do_something, this is
    # because the response will be used as the first argument automatically
    action_item = async.get(u, hooks = {'response' : do_something})

    # Add the task to our list of things to do via async
    async_list.append(action_item)

# Do our list of things to do via async
async.map(async_list)

You can use encodeURIComponent().

It will escape all the characters that cannot occur verbatim in URLs:

var wysiwyg_clean = encodeURIComponent(wysiwyg);

In this example, the ampersand character & will be replaced by the escape sequence %26, which is valid in URLs.

You can also use a MultiValue Map to hold the requestBody in. here is the example for it.

    foosId -> pathVariable
    user -> extracted from the Map of request Body 

unlike the @RequestBody annotation when using a Map to hold the request body we need to annotate with @RequestParam

and send the user in the Json RequestBody

  @RequestMapping(value = "v1/test/foos/{foosId}", method = RequestMethod.POST, headers = "Accept=application"
            + "/json",
            consumes = MediaType.APPLICATION_JSON_UTF8_VALUE ,
            produces = MediaType.APPLICATION_JSON_UTF8_VALUE)
    @ResponseBody
    public String postFoos(@PathVariable final Map<String, String> pathParam,
            @RequestParam final MultiValueMap<String, String> requestBody) {
        return "Post some Foos " + pathParam.get("foosId") + " " + requestBody.get("user");
    }

   Calendar cal = Calendar.getInstance();
   DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
   System.out.println("Today's date is "+dateFormat.format(cal.getTime()));

   cal.add(Calendar.DATE, -1);
   System.out.println("Yesterday's date was "+dateFormat.format(cal.getTime()));  

Use Calender Api

While my recommendation is to take advantage of the automation available from Doality.com specifically Picture Manager for Excel

The following vba code should meet your criteria. Good Luck!

Add a Button Control to your Excel Workbook and then double click on the button in order to get to the VBA Code -->

Sub Button1_Click()
    Dim filePathCell As Range
    Dim imageLocationCell As Range
    Dim filePath As String

    Set filePathCell = Application.InputBox(Prompt:= _
        "Please select the cell that contains the reference path to your image file", _
            Title:="Specify File Path", Type:=8)

     Set imageLocationCell = Application.InputBox(Prompt:= _
        "Please select the cell where you would like your image to be inserted.", _
            Title:="Image Cell", Type:=8)

    If filePathCell Is Nothing Then
       MsgBox ("Please make a selection for file path")
       Exit Sub
    Else
      If filePathCell.Cells.Count > 1 Then
        MsgBox ("Please select only a single cell that contains the file location")
        Exit Sub
      Else
        filePath = Cells(filePathCell.Row, filePathCell.Column).Value
      End If
    End If

    If imageLocationCell Is Nothing Then
       MsgBox ("Please make a selection for image location")
       Exit Sub
    Else
      If imageLocationCell.Cells.Count > 1 Then
        MsgBox ("Please select only a single cell where you want the image to be populated")
        Exit Sub
      Else
        InsertPic filePath, imageLocationCell
        Exit Sub
      End If
    End If
End Sub

Then create your Insert Method as follows:

Private Sub InsertPic(filePath As String, ByVal insertCell As Range)
    Dim xlShapes As Shapes
    Dim xlPic As Shape
    Dim xlWorksheet As Worksheet

    If IsEmpty(filePath) Or Len(Dir(filePath)) = 0 Then
        MsgBox ("File Path invalid")
        Exit Sub
    End If

    Set xlWorksheet = ActiveSheet

    Set xlPic = xlWorksheet.Shapes.AddPicture(filePath, msoFalse, msoCTrue, insertCell.top, insertCell.left, insertCell.width, insertCell.height)
    xlPic.LockAspectRatio = msoCTrue
End Sub

Use /config.php.

Alternatively you could use SciPy

from scipy import stats
stats.uniform(0.5, 13.3).rvs(50)

and for the record to sample integers it's

stats.randint(10, 20).rvs(50)

Here's how you can specify that with find:

find . -type f -name "*_peaks.bed" ! -path "./tmp/*" ! -path "./scripts/*"

Explanation:

• find . - Start find from current working directory (recursively by default)
• -type f - Specify to find that you only want files in the results
• -name "*_peaks.bed" - Look for files with the name ending in _peaks.bed
• ! -path "./tmp/*" - Exclude all results whose path starts with ./tmp/
• ! -path "./scripts/*" - Also exclude all results whose path starts with ./scripts/

Testing the Solution:

$ mkdir a b c d e
$ touch a/1 b/2 c/3 d/4 e/5 e/a e/b
$ find . -type f ! -path "./a/*" ! -path "./b/*"

./d/4
./c/3
./e/a
./e/b
./e/5

You were pretty close, the -name option only considers the basename, where as -path considers the entire path =)

@RequestMapping is a class level

@GetMapping is a method-level

With sprint Spring 4.3. and up things have changed. Now you can use @GetMapping on the method that will handle the http request. The class-level @RequestMapping specification is refined with the (method-level)@GetMapping annotation

Here is an example:

@Slf4j
@Controller
@RequestMapping("/orders")/* The @Request-Mapping annotation, when applied
                            at the class level, specifies the kind of requests 
                            that this controller handles*/  

public class OrderController {

@GetMapping("/current")/*@GetMapping paired with the classlevel
                        @RequestMapping, specifies that when an 
                        HTTP GET request is received for /order, 
                        orderForm() will be called to handle the request..*/

public String orderForm(Model model) {

model.addAttribute("order", new Order());

return "orderForm";
}
}

Prior to Spring 4.3, it was @RequestMapping(method=RequestMethod.GET)

ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods (".").

HTML 5 is even more permissive, saying only that an id must contain at least one character and may not contain any space characters.

The id attribute is case sensitive in XHTML.

As a purely practical matter, you may want to avoid certain characters. Periods, colons and '#' have special meaning in CSS selectors, so you will have to escape those characters using a backslash in CSS or a double backslash in a selector string passed to jQuery. Think about how often you will have to escape a character in your stylesheets or code before you go crazy with periods and colons in ids.

For example, the HTML declaration <div id="first.name"></div> is valid. You can select that element in CSS as #first\.name and in jQuery like so: $('#first\\.name'). But if you forget the backslash, $('#first.name'), you will have a perfectly valid selector looking for an element with id first and also having class name. This is a bug that is easy to overlook. You might be happier in the long run choosing the id first-name (a hyphen rather than a period), instead.

You can simplify your development tasks by strictly sticking to a naming convention. For example, if you limit yourself entirely to lower-case characters and always separate words with either hyphens or underscores (but not both, pick one and never use the other), then you have an easy-to-remember pattern. You will never wonder "was it firstName or FirstName?" because you will always know that you should type first_name. Prefer camel case? Then limit yourself to that, no hyphens or underscores, and always, consistently use either upper-case or lower-case for the first character, don't mix them.

A now very obscure problem was that at least one browser, Netscape 6, incorrectly treated id attribute values as case-sensitive. That meant that if you had typed id="firstName" in your HTML (lower-case 'f') and #FirstName { color: red } in your CSS (upper-case 'F'), that buggy browser would have failed to set the element's color to red. At the time of this edit, April 2015, I hope you aren't being asked to support Netscape 6. Consider this a historical footnote.

What is the right way to reverse a pandas DataFrame?

TL;DR: df[::-1]

This is objectively IMO the best method for reversing a DataFrame, because it is a ONE step operation, also very readable (assuming familiarity with slice notation).

Long Version

I've found the ol' slicing trick df[::-1] (or the equivalent df.loc[::-1]¹) to be the most concise and idiomatic way of reversing a DataFrame. This mirrors the python list reversal syntax lst[::-1] and is clear in its intent. With the loc syntax, you are also able to slice columns if required, so it is a bit more flexible.

Some points to consider while handling the index:

• "what if I want to reverse the index as well?"

  • you're already done. df[::-1] reverses both the index and values.

• "what if I want to drop the index from the result?"

  • you can call .reset_index(drop=True) at the end.

• "what if I want to keep the index untouched (IOW, only reverse the data, not the index)?"

  • this is somewhat unconventional because it implies the index isn't really relevant to the data. Perhaps consider removing it entirely? Although what you're asking for can technically be achieved using either df[:] = df[::-1] which creates an in-place update to df, or df.loc[::-1].set_index(df.index), which returns a copy.

_{1: df.loc[::-1] and df.iloc[::-1] are equivalent since the slicing syntax remains the same, whether you're reversing by position (iloc) or label (loc).}

The Proof is in the Pudding

X-axis represents the dataset size. Y-axis represents time taken to reverse. No method scales as well as the slicing trick, it's all the way at the bottom of the graph. Benchmarking code for reference, plots generated using perfplot.

Comments on other solutions

• df.reindex(index=df.index[::-1]) is clearly a popular solution, but on first glance, how obvious is it to an unfamiliar reader that this code is "reversing a DataFrame"? Additionally, this is reversing the index, then using that intermediate result to reindex, so this is essentially a TWO step operation (when it could've been just one).

• df.sort_index(ascending=False) may work in most cases where you have a simple range index, but this assumes your index was sorted in ascending order and so doesn't generalize well.

• PLEASE do not use iterrows. I see some options suggesting iterating in reverse. Whatever your use case, there is likely a vectorized method available, but if there isn't then you can use something a little more reasonable such as list comprehensions. See How to iterate over rows in a DataFrame in Pandas for more detail on why iterrows is an antipattern.

I am beginner to iOS development so I would like to share whole info I got in this section.

First from image assets (images.xcassets) create image set .

According to Documentation here is all sizes need to create background image.

For iPhone 5:
   640 x 1136

   For iPhone 6:
   750 x 1334 (@2x) for portrait
   1334 x 750 (@2x) for landscape

   For iPhone 6 Plus:
   1242 x 2208 (@3x) for portrait
   2208 x 1242 (@3x) for landscape

   iPhone 4s (@2x)      
   640 x 960

   iPad and iPad mini (@2x) 
   1536 x 2048 (portrait)
   2048 x 1536 (landscape)

   iPad 2 and iPad mini (@1x)
   768 x 1024 (portrait)
   1024 x 768 (landscape)

   iPad Pro (@2x)
   2048 x 2732 (portrait)
   2732 x 2048 (landscape)

call the image background we can call image from image assets by using this method UIImage(named: "background") here is full code example

  override func viewDidLoad() {
          super.viewDidLoad()
             assignbackground()
            // Do any additional setup after loading the view.
        }

  func assignbackground(){
        let background = UIImage(named: "background")

        var imageView : UIImageView!
        imageView = UIImageView(frame: view.bounds)
        imageView.contentMode =  UIViewContentMode.ScaleAspectFill
        imageView.clipsToBounds = true
        imageView.image = background
        imageView.center = view.center
        view.addSubview(imageView)
        self.view.sendSubviewToBack(imageView)
    }

Try

rows = tabDelimitedTable.split("[" + newLine + "]");

This should solve the regex problem.

Also not that important but return type of

System.getProperty("line.separator")

is String so no need to call toString().

Since version 6.0.24, Tomcat ships with a memory leak detection feature, which in turn can lead to this kind of warning messages when there's a JDBC 4.0 compatible driver in the webapp's /WEB-INF/lib which auto-registers itself during webapp's startup using the ServiceLoader API, but which did not auto-deregister itself during webapp's shutdown. This message is purely informal, Tomcat has already taken the memory leak prevention action accordingly.

What can you do?

1. Ignore those warnings. Tomcat is doing its job right. The actual bug is in someone else's code (the JDBC driver in question), not in yours. Be happy that Tomcat did its job properly and wait until the JDBC driver vendor get it fixed so that you can upgrade the driver. On the other hand, you aren't supposed to drop a JDBC driver in webapp's /WEB-INF/lib, but only in server's /lib. If you still keep it in webapp's /WEB-INF/lib, then you should manually register and deregister it using a ServletContextListener.

2. Downgrade to Tomcat 6.0.23 or older so that you will not be bothered with those warnings. But it will silently keep leaking memory. Not sure if that's good to know after all. Those kind of memory leaks are one of the major causes behind OutOfMemoryError issues during Tomcat hotdeployments.

3. Move the JDBC driver to Tomcat's /lib folder and have a connection pooled datasource to manage the driver. Note that Tomcat's builtin DBCP does not deregister drivers properly on close. See also bug DBCP-322 which is closed as WONTFIX. You would rather like to replace DBCP by another connection pool which is doing its job better then DBCP. For example HikariCP or perhaps Tomcat JDBC Pool.

What is polymorphism?

Polymorphism is the ability to:

• Invoke an operation on an instance of a specialized type by only knowing its generalized type while calling the method of the specialized type and not that of the generalized type: it is dynamic polymorphism.

• Define several methods having the save name but having differents parameters: it is static polymorphism.

The first if the historical definition and the most important.

What is polymorphism used for?

It allows to create strongly-typed consistency of the class hierarchy and to do some magical things like managing lists of objects of differents types without knowing their types but only one of their parent type, as well as data bindings.

Strong and weak typing

Sample

Here are some Shapes like Point, Line, Rectangle and Circle having the operation Draw() taking either nothing or either a parameter to set a timeout to erase it.

public class Shape
{
 public virtual void Draw()
 {
   DoNothing();
 }
 public virtual void Draw(int timeout)
 {
   DoNothing();
 }
}

public class Point : Shape
{
 int X, Y;
 public override void Draw()
 {
   DrawThePoint();
 }
}

public class Line : Point
{
 int Xend, Yend;
 public override Draw()
 {
   DrawTheLine();
 }
}

public class Rectangle : Line
{
 public override Draw()
 {
   DrawTheRectangle();
 }
}

var shapes = new List<Shape> { new Point(0,0), new Line(0,0,10,10), new rectangle(50,50,100,100) };

foreach ( var shape in shapes )
  shape.Draw();

Here the Shape class and the Shape.Draw() methods should be marked as abstract.

They are not for to make understand.

Explaination

Without polymorphism, using abstract-virtual-override, while parsing the shapes, it is only the Spahe.Draw() method that is called as the CLR don't know what method to call. So it call the method of the type we act on, and here the type is Shape because of the list declaration. So the code do nothing at all.

With polymorphism, the CLR is able to infer the real type of the object we act on using what is called a virtual table. So it call the good method, and here calling Shape.Draw() if Shape is Point calls the Point.Draw(). So the code draws the shapes.

def function(arg)->123:

It's simply a return type, integer in this case doesn't matter which number you write.

like Java :

public int function(int args){...}

But for Python (how Jim Fasarakis Hilliard said) the return type it's just an hint, so it's suggest the return but allow anyway to return other type like a string..

Sending and receiving data in JSON format using POST method

// Sending and receiving data in JSON format using POST method
//
var xhr = new XMLHttpRequest();
var url = "url";
xhr.open("POST", url, true);
xhr.setRequestHeader("Content-Type", "application/json");
xhr.onreadystatechange = function () {
    if (xhr.readyState === 4 && xhr.status === 200) {
        var json = JSON.parse(xhr.responseText);
        console.log(json.email + ", " + json.password);
    }
};
var data = JSON.stringify({"email": "[email protected]", "password": "101010"});
xhr.send(data);

Sending and receiving data in JSON format using GET method

// Sending a receiving data in JSON format using GET method
//      
var xhr = new XMLHttpRequest();
var url = "url?data=" + encodeURIComponent(JSON.stringify({"email": "[email protected]", "password": "101010"}));
xhr.open("GET", url, true);
xhr.setRequestHeader("Content-Type", "application/json");
xhr.onreadystatechange = function () {
    if (xhr.readyState === 4 && xhr.status === 200) {
        var json = JSON.parse(xhr.responseText);
        console.log(json.email + ", " + json.password);
    }
};
xhr.send();

Handling data in JSON format on the server-side using PHP

<?php
// Handling data in JSON format on the server-side using PHP
//
header("Content-Type: application/json");
// build a PHP variable from JSON sent using POST method
$v = json_decode(stripslashes(file_get_contents("php://input")));
// build a PHP variable from JSON sent using GET method
$v = json_decode(stripslashes($_GET["data"]));
// encode the PHP variable to JSON and send it back on client-side
echo json_encode($v);
?>

The limit of the length of an HTTP Get request is dependent on both the server and the client (browser) used, from 2kB - 8kB. The server should return 414 (Request-URI Too Long) status if an URI is longer than the server can handle.

Note Someone said that I could use state names instead of state values; in other words I could use xhr.readyState === xhr.DONE instead of xhr.readyState === 4 The problem is that Internet Explorer uses different state names so it's better to use state values.

You can use xsd as suggested by Darin.

In addition to that it is recommended to edit the test.xsd-file to create a more reasonable schema.

type="xs:string" can be changed to type="xs:int" for integer values
minOccurs="0" can be changed to minOccurs="1" where the field is required
maxOccurs="unbounded" can be changed to maxOccurs="1" where only one item is allowed

You can create more advanced xsd-s if you want to validate your data further, but this will at least give you reasonable data types in the generated c#.

Best way to execute block of code after Spring Boot application started is using PostConstruct annotation.Or also you can use command line runner for the same.

1. Using PostConstruct annotation

@Configuration
public class InitialDataConfiguration {

    @PostConstruct
    public void postConstruct() {
        System.out.println("Started after Spring boot application !");
    }

}

2. Using command line runner bean

@Configuration
public class InitialDataConfiguration {

    @Bean
    CommandLineRunner runner() {
        return args -> {
            System.out.println("CommandLineRunner running in the UnsplashApplication class...");
        };
    }
}

i also appear this problem,and my code below

        storeFile file(properties.getProperty("filepath"))
        storePassword properties.getProperty("keypassword")
        keyAlias properties.getProperty("keyAlias")
        keyPassword properties.getProperty("keypassword")

the reason is property name error,it should be keyPassword not keypassword

The orderBy method requires either two strings or an Expr\OrderBy object. If you want to add multiple order declarations, the correct thing is to use addOrderBy method, or instantiate an OrderBy object and populate it accordingly:

   # Inside a Repository method:
   $myResults = $this->createQueryBuilder('a')
       ->addOrderBy('a.column1', 'ASC')
       ->addOrderBy('a.column2', 'ASC')
       ->addOrderBy('a.column3', 'DESC')
   ;

   # Or, using a OrderBy object:
   $orderBy = new OrderBy('a.column1', 'ASC');
   $orderBy->add('a.column2', 'ASC');
   $orderBy->add('a.column3', 'DESC');

   $myResults = $this->createQueryBuilder('a')
       ->orderBy($orderBy)
   ;

Also if you want different status-bar color for different activity (fragments) you can do it with following steps (work on API 21 and above):

First create values21/style.xml and put following code:

 <style name="AIO" parent="AIOBase">
            <item name="android:windowDrawsSystemBarBackgrounds">true</item>
            <item name="android:windowContentTransitions">true</item>
    </style>

Then define White|Dark themes in your values/style.xml like following:

 <style name="AIOBase" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="colorPrimary">@color/color_primary</item>
        <item name="colorPrimaryDark">@color/color_primary_dark</item>
        <item name="colorAccent">@color/color_accent</item>
        <item name="android:textColorPrimary">@android:color/black</item>
        <item name="android:statusBarColor" tools:targetApi="lollipop">@color/color_primary_dark
        </item>
        <item name="android:textColor">@color/gray_darkest</item>
        <item name="android:windowBackground">@color/default_bg</item>
        <item name="android:colorBackground">@color/default_bg</item>
    </style>


    <style name="AIO" parent="AIOBase" />

    <style name="AIO.Dark" parent="AIOBase">
        <item name="android:statusBarColor" tools:targetApi="lollipop">#171717
        </item>
    </style>

    <style name="AIO.White" parent="AIOBase">
        <item name="android:statusBarColor" tools:targetApi="lollipop">#bdbdbd
        </item>
    </style>

Also don't forget to apply themes in your manifest.xml.

The execmgr.log will show the commandline and ccmcache folder used for installation. Typically, required apps don't show on appenforce.log and some clients will have outdated appenforce or no ppenforce.log files. execmgr.log also shows required hidden uninstall actions as well.

You may want to save the blog link. I still reference it from time to time.

I usually do this

in my store() function i put success alert once it saved properly.

\Session::flash('flash_message','Office successfully updated.');

in my destroy() function, I wanted to color the alert red so to notify that its deleted

\Session::flash('flash_message_delete','Office successfully deleted.');

Notice, we create two alerts with different flash names.

And in my view, I will add condtion to when the right time the specific alert will be called

@if(Session::has('flash_message'))
    <div class="alert alert-success"><span class="glyphicon glyphicon-ok"></span><em> {!! session('flash_message') !!}</em></div>
@endif
@if(Session::has('flash_message_delete'))
    <div class="alert alert-danger"><span class="glyphicon glyphicon-ok"></span><em> {!! session('flash_message_delete') !!}</em></div>
@endif

Here you can find different flash message stlyes Flash Messages in Laravel 5

laravel have own function skip for offset and take for limit. just like below example of laravel query :-

Article::where([['user_id','=',auth()->user()->id]])
                ->where([['title','LIKE',"%".$text_val."%"]])
                ->orderBy('id','DESC')
                ->skip(0)
                ->take(2)
                ->get();

taskkill /f /im "devenv.exe"

this will forcibly kill the pid with the exe name "devenv.exe"

equivalent to -9 on the nix'y kill command

For readability, I restructured the query... starting with the apparent top-most level being Table1, which then ties to Table3, and then table3 ties to table2. Much easier to follow if you follow the chain of relationships.

Now, to answer your question. You are getting a large count as the result of a Cartesian product. For each record in Table1 that matches in Table3 you will have X * Y. Then, for each match between table3 and Table2 will have the same impact... Y * Z... So your result for just one possible ID in table 1 can have X * Y * Z records.

This is based on not knowing how the normalization or content is for your tables... if the key is a PRIMARY key or not..

Ex:
Table 1       
DiffKey    Other Val
1          X
1          Y
1          Z

Table 3
DiffKey   Key    Key2  Tbl3 Other
1         2      6     V
1         2      6     X
1         2      6     Y
1         2      6     Z

Table 2
Key    Key2   Other Val
2      6      a
2      6      b
2      6      c
2      6      d
2      6      e

So, Table 1 joining to Table 3 will result (in this scenario) with 12 records (each in 1 joined with each in 3). Then, all that again times each matched record in table 2 (5 records)... total of 60 ( 3 tbl1 * 4 tbl3 * 5 tbl2 )count would be returned.

So, now, take that and expand based on your 1000's of records and you see how a messed-up structure could choke a cow (so-to-speak) and kill performance.

SELECT
      COUNT(*)
   FROM
      Table1 
         INNER JOIN Table3
            ON Table1.DifferentKey = Table3.DifferentKey
            INNER JOIN Table2
               ON Table3.Key =Table2.Key
               AND Table3.Key2 = Table2.Key2 

Obsolete: This answer is correct only for an older version of Notepad++. Converting between tabs/spaces is now built into Notepad++ and the TextFX plugin is no longer available in the Plugin Manager dialog.

• First set the "replace by spaces" setting in Preferences -> Language Menu/Tab Settings.
• Next, open the document you wish to replace tabs with.
• Highlight all the text (CTRL+A).
• Then select TextFX -> TextFX Edit -> Leading spaces to tabs or tabs to spaces.

Note: Make sure TextFX Characters plugin is installed (Plugins -> Plugin manager -> Show plugin manager, Installed tab). Otherwise, there will be no TextFX menu.

Not just specific to MySQL, the difference between float and decimal types is the way that they represent fractional values. Floating point types represent fractions in binary, which can only represent values as {m*2^n | m, n Integers} . values such as 1/5 cannot be precisely represented (without round off error). Decimal numbers are similarly limited, but represent numbers like {m*10^n | m, n Integers}. Decimals still cannot represent numbers like 1/3, but it is often the case in many common fields, like finance, that the expectation is that certain decimal fractions can always be expressed without loss of fidelity. Since a decimal number can represent a value like $0.20 (one fifth of a dollar), it is preferred in those situations.

For this format (assuming datepart has the format dd-mm-yyyy) in plain javascript use dateString2Date.

You should reference the textarea ID and include the runat="server" attribute to the textarea

message.Body = TextArea1.Text;  

What is test123?

I have just published a Nuget package that allows setting up not only the first level Properties but also nested properties in the given object in any depth.

Here is the package

Sets the value of a property of an object by its path from the root.

The object can be a complex object and the property can be multi level deep nested property or it can be a property directly under the root. ObjectWriter will find the property using the property path parameter and update its value. Property path is the appended names of the properties visited from root to the end node property which we want to set, delimited by the delimiter string parameter.

Usage:

For setting up the properties directly under the object root:

Ie. LineItem class has an int property called ItemId

LineItem lineItem = new LineItem();

ObjectWriter.Set(lineItem, "ItemId", 13, delimiter: null);

For setting up nested property multiple levels below the object root:

Ie. Invite class has a property called State, which has a property called Invite (of Invite type), which has a property called Recipient, which has a property called Id.

To make things even more complex, the State property is not a reference type, it is a struct.

Here is how you can set the Id property (to string value of “outlook”) at the bottom of the object tree in a single line.

Invite invite = new Invite();

ObjectWriter.Set(invite, "State_Invite_Recipient_Id", "outlook", delimiter: "_");

Do you only need to load jquery?

1) Like the other guides say, register your script in your functions.php file like so:

// register scripts
if (!is_admin()) {
    // here is an example of loading a custom script in a /scripts/ folder in your theme:
    wp_register_script('sandbox.common', get_bloginfo('template_url').'/scripts/common.js', array('jquery'), '1.0', true);
    // enqueue these scripts everywhere
    wp_enqueue_script('jquery');
    wp_enqueue_script('sandbox.common');
}

2) Notice that we don't need to register jQuery because it's already in the core. Make sure wp_footer() is called in your footer.php and wp_head() is called in your header.php (this is where it will output the script tag), and jQuery will load on every page. When you enqueue jQuery with WordPress it will be in "no conflict" mode, so you have to use jQuery instead of $. You can deregister jQuery if you want and re-register your own by doing wp_deregister_script('jquery').

int[] b = new int[3];
Array.Copy(a, 1, b, 0, 3);

• a = source array
• 1 = start index in source array
• b = destination array
• 0 = start index in destination array
• 3 = elements to copy

Try =index(ARRAY, ROW, COLUMN)

where: Array: select the whole sheet Row, Column: Your row and column references

That should be easier to understand to those looking at the formula.

This works:

myWindow = window.open('http://www.yahoo.com','myWindow', "width=200, height=200");

You could do it this way:

-- Notice how STATE got moved inside the condition:
CASE WHEN STATE = 2 AND RetailerProcessType IN (1, 2) THEN '"AUTHORISED"'
     WHEN STATE = 1 AND RetailerProcessType = 2 THEN '"PENDING"'
     ELSE '"DECLINED"'
END

The reason you can do an AND here is that you are not checking the CASE of STATE, but instead you are CASING Conditions.

The key part here is that the STATE condition is a part of the WHEN.

man ssh gives me this options would could be useful.

-i identity_file Selects a file from which the identity (private key) for RSA or DSA authentication is read. The default is ~/.ssh/identity for protocol version 1, and ~/.ssh/id_rsa and ~/.ssh/id_dsa for pro- tocol version 2. Identity files may also be specified on a per- host basis in the configuration file. It is possible to have multiple -i options (and multiple identities specified in config- uration files).

So you could create an alias in your bash config with something like

alias ssh="ssh -i /path/to/private_key"

I haven't looked into a ssh configuration file, but like the -i option this too could be aliased

-F configfile Specifies an alternative per-user configuration file. If a configuration file is given on the command line, the system-wide configuration file (/etc/ssh/ssh_config) will be ignored. The default for the per-user configuration file is ~/.ssh/config.

What you want to do is separate the content of the table from the header of the table. You want only the <th> elements to be scrolled. You can easily define this separation in HTML with the <tbody> and the <thead> elements.
Now the header and the body of the table are still connected to each other, they will still have the same width (and same scroll properties). Now to let them not 'work' as a table anymore you can set the display: block. This way <thead> and <tbody> are separated.

table tbody, table thead
{
    display: block;
}

Now you can set the scroll to the body of the table:

table tbody 
{
   overflow: auto;
   height: 100px;
}

And last, because the <thead> doesn't share the same width as the body anymore, you should set a static width to the header of the table:

th
{
    width: 72px;
}

You should also set a static width for <td>. This solves the issue of the unaligned columns.

td
{
    width: 72px;
}

<tr>
     <th>head1</th>
     <th>head2</th>
     <th>head3</th>
     <th>head4</th>
</tr>

I hope this is what you meant.

jsFiddle

Addendum

If you would like to have more control over the column widths, have them to vary in width between each other, and course keep the header and body columns aligned, you can use the following example:

    table th:nth-child(1), td:nth-child(1) { min-width: 50px;  max-width: 50px; }
    table th:nth-child(2), td:nth-child(2) { min-width: 100px; max-width: 100px; }
    table th:nth-child(3), td:nth-child(3) { min-width: 150px; max-width: 150px; }
    table th:nth-child(4), td:nth-child(4) { min-width: 200px; max-width: 200px; }

You should use the following code :

Class2 cls2 = new Class2();
cls2.UpdateEmployee();

In case you don't want to create a new instance to call the method, you can decalre the method as static and then you can just call Class2.UpdateEmployee().

You can creat the table you want, save it as an image and then use an image map to creat the link (this way you can put the coords of the hole td to make it in to a link).

If you want to declare date and then use it in SQL Developer.

DEFINE PROPp_START_DT = TO_DATE('01-SEP-1999')

SELECT * 
FROM proposal 
WHERE prop_start_dt = &PROPp_START_DT

On Framework 4.5 the AppSettings.Settings["key"] part of ConfigurationManager is read only so I had to first Remove the key then Add it again using the following:

Configuration config = ConfigurationManager.OpenExeConfiguration(Application.ExecutablePath);

config.AppSettings.Settings.Remove("MySetting");
config.AppSettings.Settings.Add("MySetting", "some value");

config.Save(ConfigurationSaveMode.Modified);

Don't worry, you won't get an exception if you try to Remove a key that doesn't exist.

This post gives some good advice

CNAME'ing a root record is technically not against RFC, but does have limitations meaning it is a practice that is not recommended.

Normally your root record will have multiple entries. Say, 3 for your name servers and then one for an IP address.

Per RFC:

If a CNAME RR is present at a node, no other data should be present;

And Per IETF 'Common DNS Operational and Configuration Errors' Document:

This is often attempted by inexperienced administrators as an obvious way to allow your domain name to also be a host. However, DNS servers like BIND will see the CNAME and refuse to add any other resources for that name. Since no other records are allowed to coexist with a CNAME, the NS entries are ignored. Therefore all the hosts in the podunk.xx domain are ignored as well!

References:

• http://tools.ietf.org/html/rfc1912 section '2.4 CNAME Records'
• http://www.faqs.org/rfcs/rfc1034.html section '3.6.2. Aliases and canonical names'

Use your system's daemon facility, such as start-stop-daemon.

Otherwise, yes, there has to be a loop somewhere.

In C++ the only difference between a class and a struct is that members and base classes are private by default in classes, whereas they are public by default in structs.

So structs can have constructors, and the syntax is the same as for classes.

Welcome to bash. It's an old, dark and mysterious thing, capable of great magic. :-)

The option you're asking about is for the find command though, not for bash. From your command line, you can man find to see the options.

The one you're looking for is -o for "or":

  list="$(find /home/user/Desktop -name '*.bmp' -o -name '*.txt')"

That said ... Don't do this. Storage like this may work for simple filenames, but as soon as you have to deal with special characters, like spaces and newlines, all bets are off. See ParsingLs for details.

$ touch 'one.txt' 'two three.txt' 'foo.bmp'
$ list="$(find . -name \*.txt -o -name \*.bmp -type f)"
$ for file in $list; do if [ ! -f "$file" ]; then echo "MISSING: $file"; fi; done
MISSING: ./two
MISSING: three.txt

Pathname expansion (globbing) provides a much better/safer way to keep track of files. Then you can also use bash arrays:

$ a=( *.txt *.bmp )
$ declare -p a
declare -a a=([0]="one.txt" [1]="two three.txt" [2]="foo.bmp")
$ for file in "${a[@]}"; do ls -l "$file"; done
-rw-r--r--  1 ghoti  staff  0 24 May 16:27 one.txt
-rw-r--r--  1 ghoti  staff  0 24 May 16:27 two three.txt
-rw-r--r--  1 ghoti  staff  0 24 May 16:27 foo.bmp

The Bash FAQ has lots of other excellent tips about programming in bash.

use :get and :delete method for your path:

devise_scope :user do
  match '/users/sign_out' => 'devise/sessions#destroy', :as => :destroy_user_session, via: [:get, :delete]
end

Another option, in addition to using OPENQUERY and xp_cmdshell, is to use SQLCLR (SQL Server's "CLR Integration" feature). Not only is the SQLCLR option more secure than those other two methods, but there is also the potential benefit of being able to call the stored procedure in the current session such that it would have access to any session-based objects or settings, such as:

• temporary tables
• temporary stored procedures
• CONTEXT_INFO

This can be achieved by using "context connection = true;" as the ConnectionString. Just keep in mind that all other restrictions placed on T-SQL User-Defined Functions will be enforced (i.e. cannot have any side-effects).

If you use a regular connection (i.e. not using the context connection), then it will operate as an independent call, just like it does when using the OPENQUERY and xp_cmdshell methods.

HOWEVER, please keep in mind that if you will be using a function that calls a stored procedure (regardless of which of the 3 noted methods you use) in a statement that affects more than 1 row, then the behavior cannot be expected to run once per row. As @MartinSmith mentioned in a comment on @MatBailie's answer, the Query Optimizer does not guarantee either the timing or number of executions of functions. But if you are using it in a SET @Variable = function(); statement or SELECT * FROM function(); query, then it should be ok.

An example of using a .NET / C# SQLCLR user-defined function to execute a stored procedure is shown in the following article (which I wrote):

Stairway to SQLCLR Level 2: Sample Stored Procedure and Function

I know that there are a lot of answers to this question already already but i wanted to share my experience as none of the answers provided fixed this issue for me.

After about a day of exploring different solutions I believe the issue was that I have recently installed XAMPP and it was interfering with the MySQL workbench. I have tried changing the port numbers however this hasn't helped, and it seems that both programs are sharing configuration files. Repairing MySQL in the Control Panel didn't resolve it, so now I am uninstalling MySQL and plan to reinstall it. Another potential solution maybe to uninstall XAMPP however the config files may either be deleted, or left in the xampp folder instead of the MySQL folder by doing so.

If you only want to log the query, then add 'logger' and 'profileSQL' to the jdbc url:

&logger=com.mysql.jdbc.log.Slf4JLogger&profileSQL=true

Then you will get the SQL statement below:

If you want to pull a particular file from another branch just do

git checkout branch1 -- filenamefoo.txt

This will pull a version of the file from one branch into the current tree

The easier is add [0] - select first value of list with one element:

dfb = df[df['A']==5].index.values.astype(int)[0]
dfbb = df[df['A']==8].index.values.astype(int)[0]

dfb = int(df[df['A']==5].index[0])
dfbb = int(df[df['A']==8].index[0])

But if possible some values not match, error is raised, because first value not exist.

Solution is use next with iter for get default parameetr if values not matched:

dfb = next(iter(df[df['A']==5].index), 'no match')
print (dfb)
4

dfb = next(iter(df[df['A']==50].index), 'no match')
print (dfb)
no match

Then it seems need substract 1:

print (df.loc[dfb:dfbb-1,'B'])
4    0.894525
5    0.978174
6    0.859449
Name: B, dtype: float64

Another solution with boolean indexing or query:

print (df[(df['A'] >= 5) & (df['A'] < 8)])
   A         B
4  5  0.894525
5  6  0.978174
6  7  0.859449

print (df.loc[(df['A'] >= 5) & (df['A'] < 8), 'B'])
4    0.894525
5    0.978174
6    0.859449
Name: B, dtype: float64

print (df.query('A >= 5 and A < 8'))
   A         B
4  5  0.894525
5  6  0.978174
6  7  0.859449

this worked for me:

URL u = new URL ( "http://www.example.com/");
HttpURLConnection huc =  ( HttpURLConnection )  u.openConnection (); 
huc.setRequestMethod ("GET");  //OR  huc.setRequestMethod ("HEAD"); 
huc.connect () ; 
int code = huc.getResponseCode() ;
System.out.println(code);

thanks for the suggestions above.

Set SELinux in Permissive Mode using the command below:

PHP provides two types of array.

• normal array
• SplFixedArray

normal array : This array is dynamic.

SplFixedArray : this is a standard php library which provides the ability to create array of fix size.

I recommend to use SMO (Enable TCP/IP Network Protocol for SQL Server). However, it was not available in my case.

I rewrote the WMI commands from Krzysztof Kozielczyk to PowerShell.

# Enable TCP/IP

Get-CimInstance -Namespace root/Microsoft/SqlServer/ComputerManagement10 -ClassName ServerNetworkProtocol -Filter "InstanceName = 'SQLEXPRESS' and ProtocolName = 'Tcp'" |
Invoke-CimMethod -Name SetEnable

# Open the right ports in the firewall
New-NetFirewallRule -DisplayName 'MSSQL$SQLEXPRESS' -Direction Inbound -Action Allow -Protocol TCP -LocalPort 1433

# Modify TCP/IP properties to enable an IP address

$properties = Get-CimInstance -Namespace root/Microsoft/SqlServer/ComputerManagement10 -ClassName ServerNetworkProtocolProperty -Filter "InstanceName='SQLEXPRESS' and ProtocolName = 'Tcp' and IPAddressName='IPAll'"
$properties | ? { $_.PropertyName -eq 'TcpPort' } | Invoke-CimMethod -Name SetStringValue -Arguments @{ StrValue = '1433' }
$properties | ? { $_.PropertyName -eq 'TcpPortDynamic' } | Invoke-CimMethod -Name SetStringValue -Arguments @{ StrValue = '' }

# Restart SQL Server

Restart-Service 'MSSQL$SQLEXPRESS'

Another way to add that I used to 'hack' this solution was to do this: I set up a seperate computed value that would simply return the nested object value.

data : function(){
    return {
        my_object : {
            my_deep_object : {
                my_value : "hello world";
            }.
        },
    };
},
computed : {
    helper_name : function(){
        return this.my_object.my_deep_object.my_value;
    },
},
watch : {
    helper_name : function(newVal, oldVal){
        // do this...
    }
}

You can also use T-Regx library which has automatic delimiters for you:

$matches = pattern("My name is '(.*)' and im fine")->match($string1)->all();

                 // ? No delimiters needed 

I was able to build a library source code to compiled .jar file, using approach from this solution: https://stackoverflow.com/a/19037807/1002054

Here is the breakdown of what I did:

1. Checkout library repository

In may case it was a Volley library

2. Import library in Android Studio.

I used Android Studio 0.3.7. I've encountered some issues during that step, namely I had to copy gradle folder from new android project before I was able to import Volley library source code, this may vary depending on source code you use.

3. Modify your build.gradle file

// If your module is a library project, this is needed
//to properly recognize 'android-library' plugin
buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.6.3'
    }
}

apply plugin: 'android-library'

android {
    compileSdkVersion 17
    buildToolsVersion = 17

    sourceSets {
        main  {
            // Here is the path to your source code
            java {
                srcDir 'src'
            }
        }
    }
}

// This is the actual solution, as in https://stackoverflow.com/a/19037807/1002054
task clearJar(type: Delete) {
    delete 'build/libs/myCompiledLibrary.jar'
}

task makeJar(type: Copy) {
    from('build/bundles/release/')
    into('build/libs/')
    include('classes.jar')
    rename ('classes.jar', 'myCompiledLibrary.jar')
}

makeJar.dependsOn(clearJar, build)

4. Run gradlew makeJar command from your project root.

I my case I had to copy gradlew.bat and gradle files from new android project into my library project root. You should find your compiled library file myCompiledLibrary.jar in build\libs directory.

I hope someone finds this useful.

Edit:

Caveat

Althought this works, you will encounter duplicate library exception while compiling a project with multiple modules, where more than one module (including application module) depends on the same jar file (eg. modules have own library directory, that is referenced in build.gradle of given module).

In case where you need to use single library in more then one module, I would recommend using this approach: Android gradle build and the support library

You are running your HTML from a different host than the host you are requesting. Because of this, you are getting blocked by the same origin policy.

One way around this is to use JSONP. This allows cross-site requests.

In JSON, you are returned:

{a: 5, b: 6}

In JSONP, the JSON is wrapped in a function call, so it becomes a script, and not an object.

callback({a: 5, b: 6})

You need to edit your REST service to accept a parameter called callback, and then to use the value of that parameter as the function name. You should also change the content-type to application/javascript.

For example: http://localhost:8080/restws/json/product/get?callback=process should output:

process({a: 5, b: 6})

In your JavaScript, you will need to tell jQuery to use JSONP. To do this, you need to append ?callback=? to the URL.

$.getJSON("http://localhost:8080/restws/json/product/get?callback=?",
   function(data) {
     alert(data);         
   });

If you use $.ajax, it will auto append the ?callback=? if you tell it to use jsonp.

$.ajax({ 
   type: "GET",
   dataType: "jsonp",
   url: "http://localhost:8080/restws/json/product/get",
   success: function(data){        
     alert(data);
   }
});

Hope this tip will save someone else's life. In my case the problem was that I ran out of memory, but only slightly, was hard to think about it. Wasted 3hrs on that. I recommend running:

sudo htop

or

sudo free -m

...along with running problematic requests on the server to see if your memory doesn't run out. And if it does like in my case, you need to create a swap file (unless you already have one).

I have followed this tutorial to create swap file on Ubuntu Server 14.04 and it worked just fine: http://www.cyberciti.biz/faq/ubuntu-linux-create-add-swap-file/

Try this,

<?php  if ( ($cart->count_product) > 0) { ?>
         <div class="my_class"><?php print $cart->count_product; ?></div>
<?php } else { 
          print ''; 
}  ?>

It's a bit late but I just had the same problem and finally solved it with the help of another stackoverflow post (https://stackoverflow.com/a/29103071).

img {
   object-fit: cover;
   width: 50px;
   height: 100px;
}

Hope this still helps somebody.

Ps: Also works together with max-height, max-width, min-width and min-height css properties. It's espacially handy with using lenght units like 100% or 100vh/100vw to fill the container or the whole browser window.

When you install PostgreSQL using Homebrew,

brew install postgres

at the end of the output, you will see this methods to start the server:

To have launchd start postgresql at login:
    ln -sfv /usr/local/opt/postgresql/*.plist ~/Library/LaunchAgents
Then to load postgresql now:
    launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
Or, if you don't want/need launchctl, you can just run:
    postgres -D /usr/local/var/postgres

I think this is the best way.

You can add an alias into your .profile file for convenience.

I encountered this problem today as well. I am using Windows and the system language by default is Chinese. Hence, someone may encounter this Unicode error similarly. Simply add encoding = 'utf-8':

with open("test.html", "r", encoding='utf-8') as f:
    text= f.read()

You can't pass str to your model fit() method. as it mentioned here

The training input samples. Internally, it will be converted to dtype=np.float32 and if a sparse matrix is provided to a sparse csc_matrix.

Try transforming your data to float and give a try to LabelEncoder.

Thanks to this post, my full css for cross browser happiness is:

<style>
    .backgroundpic {
        background-image: url('img/home.jpg');
        background-size: cover;
        filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(
        src='img/home.jpg',
        sizingMethod='scale');
    }
</style>

It's been so long since I've worked on this piece of code, but I'd like to add for more browser compatibility I've appended this to my CSS for more browser compatibility:

-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;

String hexToAscii(String s) {
  int n = s.length();
  StringBuilder sb = new StringBuilder(n / 2);
  for (int i = 0; i < n; i += 2) {
    char a = s.charAt(i);
    char b = s.charAt(i + 1);
    sb.append((char) ((hexToInt(a) << 4) | hexToInt(b)));
  }
  return sb.toString();
}

private static int hexToInt(char ch) {
  if ('a' <= ch && ch <= 'f') { return ch - 'a' + 10; }
  if ('A' <= ch && ch <= 'F') { return ch - 'A' + 10; }
  if ('0' <= ch && ch <= '9') { return ch - '0'; }
  throw new IllegalArgumentException(String.valueOf(ch));
}

PHP runs on the server and Javascript runs on the client, so you can't set a PHP variable to equal a Javascript variable without sending the value to the server. You can, however, set a Javascript variable to equal a PHP variable:

<script type="text/javascript">
  var foo = '<?php echo $foo ?>';
</script>

To send a Javascript value to PHP you'd need to use AJAX. With jQuery, it would look something like this (most basic example possible):

var variableToSend = 'foo';
$.post('file.php', {variable: variableToSend});

On your server, you would need to receive the variable sent in the post:

$variable = $_POST['variable'];

It looks like you are executing the query in sqlplus. Sqlplus needs to ensure that there is enough room in the column spacing so the maximum string size can be displayed(255). Usually, the solution is to use the column formatting options(Run prior to the query: column A format A20) to reduce the maximum string size (lines that exceed this length will be displayed over multiple lines).

The code should instead be something like this:

TextView text = (TextView) findViewById(R.id.this_is_the_id_of_textview);
text.setText("test");

A late answer, yet another definition:

A package is represented by an imported top-entity which could either be a self-contained module, or the __init__.py special module as the top-entity from a set of modules within a sub directory structure.

So physically a package is a distribution unit, which provides one or more modules.

Either use an Allias in the table like T and use T.ID, or use just the column name.

declare @TEMP table (ID int, Name varchar(max))
insert into @temp SELECT ID, Name FROM Table

SELECT * FROM @TEMP 
WHERE ID  = 1 

Technically, you should update a copyright year only if you made contributions to the work during that year. So if your website hasn't been updated in a given year, there is no ground to touch the file just to update the year.
