Since PostgreSQL JDBC driver version 8.4-701 the PreparedStatement#getGeneratedKeys() is finally fully functional. We use it here almost one year in production to our full satisfaction.

In "plain JDBC" the PreparedStatement needs to be created as follows to make it to return the keys:

statement = connection.prepareStatement(SQL, Statement.RETURN_GENERATED_KEYS);

You can download the current JDBC driver version here (which is at the moment still 8.4-701).

This uses the system perl and clean regular expressions:

cat parameters.ini | perl -0777ne 'print "$1" if /\[\s*parameters\.ini\s*\][\s\S]*?\sdatabase_version\s*=\s*(.*)/'

The integrated debuggers where you can watch the values of variable change as you step through code are really cool. They do, however, require software setup on the server and a certain amount of configuration on the client. Both of which require periodic maintenance to keep in good working order.

A print_r is easy to write and is guaranteed to work in any setup.

Setting the image using picture.ImageLocation() works fine, but you are using a relative path. Check your path against the location of the .exe after it is built.

For example, if your .exe is located at:

<project folder>/bin/Debug/app.exe

The image would have to be at:

<project folder>/bin/Image/1.jpg

Of course, you could just set the image at design-time (the Image property on the PictureBox property sheet).

If you must set it at run-time, one way to make sure you know the location of the image is to add the image file to your project. For example, add a new folder to your project, name it Image. Right-click the folder, choose "Add existing item" and browse to your image (be sure the file filter is set to show image files). After adding the image, in the property sheet set the Copy to Output Directory to Copy if newer.

At this point the image file will be copied when you build the application and you can use

picture.ImageLocation = @"Image\1.jpg"; 

This post is a little bit old, but here is another easy solution for getting data related to SMS content provider in Android:

Use this lib: https://github.com/EverythingMe/easy-content-providers

• Get all SMS:

  TelephonyProvider telephonyProvider = new TelephonyProvider(context);
  List<Sms> smses = telephonyProvider.getSms(Filter.ALL).getList();
  

  Each Sms has all fields, so you can get any info you need:
  address, body, receivedDate, type(INBOX, SENT, DRAFT, ..), threadId, ...

• Gel all MMS:

  List<Mms> mmses = telephonyProvider.getMms(Filter.ALL).getList();
  

• Gel all Thread:

  List<Thread> threads = telephonyProvider.getThreads().getList();
  

• Gel all Conversation:

  List<Conversation> conversations = telephonyProvider.getConversations().getList();
  

It works with List or Cursor and there is a sample app to see how it looks and works.

In fact, there is a support for all Android content providers like: Contacts, Call logs, Calendar, ... Full doc with all options: https://github.com/EverythingMe/easy-content-providers/wiki/Android-providers

Hope it also helped :)

Basically you tried to use a nil value in places where Swift allows only non-nil ones, by telling the compiler to trust you that there will never be nil value there, thus allowing your app to compile.

There are several scenarios that lead to this kind of fatal error:

1. forced unwraps:

   let user = someVariable!
   

   If someVariable is nil, then you'll get a crash. By doing a force unwrap you moved the nil check responsibility from the compiler to you, basically by doing a forced unwrap you're guaranteeing to the compiler that you'll never have nil values there. And guess what it happens if somehow a nil value ends in in someVariable?

   Solution? Use optional binding (aka if-let), do the variable processing there:

   if user = someVariable {
       // do your stuff
   }
   

2. forced (down)casts:

   let myRectangle = someShape as! Rectangle
   

   Here by force casting you tell the compiler to no longer worry, as you'll always have a Rectangle instance there. And as long as that holds, you don't have to worry. The problems start when you or your colleagues from the project start circulating non-rectangle values.

   Solution? Use optional binding (aka if-let), do the variable processing there:

   if let myRectangle = someShape as? Rectangle {
       // yay, I have a rectangle
   }
   

3. Implicitly unwrapped optionals. Let's assume you have the following class definition:

   class User {
       var name: String!
   
       init() {
           name = "(unnamed)"
       }
   
       func nicerName() {
           return "Mr/Ms " + name
       }
   }
   

   Now, if no-one messes up with the name property by setting it to nil, then it works as expected, however if User is initialized from a JSON that lacks the name key, then you get the fatal error when trying to use the property.

   Solution? Don't use them :) Unless you're 102% sure that the property will always have a non-nil value by the time it needs to be used. In most cases converting to an optional or non-optional will work. Making it non-optional will also result in the compiler helping you by telling the code paths you missed giving a value to that property

4. Unconnected, or not yet connected, outlets. This is a particular case of scenario #3. Basically you have some XIB-loaded class that you want to use.

   class SignInViewController: UIViewController {
   
       @IBOutlet var emailTextField: UITextField!
   }
   

   Now if you missed connecting the outlet from the XIB editor, then the app will crash as soon as you'll want to use the outlet. Solution? Make sure all outlets are connected. Or use the ? operator on them: emailTextField?.text = "[email protected]". Or declare the outlet as optional, though in this case the compiler will force you to unwrap it all over the code.

5. Values coming from Objective-C, and that don't have nullability annotations. Let's assume we have the following Objective-C class:

   @interface MyUser: NSObject
   @property NSString *name;
   @end
   

   Now if no nullability annotations are specified (either explicitly or via NS_ASSUME_NONNULL_BEGIN/NS_ASSUME_NONNULL_END), then the name property will be imported in Swift as String! (an IUO - implicitly unwrapped optional). As soon as some swift code will want to use the value, it will crash if name is nil.

   Solution? Add nullability annotations to your Objective-C code. Beware though, the Objective-C compiler is a little bit permissive when it comes to nullability, you might end up with nil values, even if you explicitly marked them as nonnull.

__get, __set, __call and __callStatic are invoked when the method or property is inaccessible. Your $bar is public and therefor not inaccessible.

See the section on Property Overloading in the manual:

• __set() is run when writing data to inaccessible properties.
• __get() is utilized for reading data from inaccessible properties.

The magic methods are not substitutes for getters and setters. They just allow you to handle method calls or property access that would otherwise result in an error. As such, there are much more related to error handling. Also note that they are considerably slower than using proper getter and setter or direct method calls.

Here is a generic LINQ extension method that does not create an extra copy of the list:

public static void Sort<T,U>(this List<T> list, Func<T, U> expression)
    where U : IComparable<U>
{
    list.Sort((x, y) => expression.Invoke(x).CompareTo(expression.Invoke(y)));
}

To use it:

myList.Sort(x=> x.myProperty);

I recently built this additional one which accepts an ICompare<U>, so that you can customize the comparison. This came in handy when I needed to do a Natural string sort:

public static void Sort<T, U>(this List<T> list, Func<T, U> expression, IComparer<U> comparer)
    where U : IComparable<U>
{    
    list.Sort((x, y) => comparer.Compare(expression.Invoke(x), expression.Invoke(y)));
}

You can use jsonpipe if you just need the output (and more comfortable with command line):

cat bookmarks.json | jsonpipe |grep uri

there is no native interfaces in JavaScript, there are several ways to simulate an interface. i have written a package that does it

you can see the implantation here

TRIM(BOTH chr(13)||chr(10)||' ' FROM str)

Open IIS manager, select Application Pools, select the application pool you are using, click on Advanced Settings in the right-hand menu. Under General, set "Enable 32-Bit Applications" to "True".

Because this is javascript and dynamic you could define your own class that matches the File interface and use that instead.

I had to do just that with dropzone.js because I wanted to simulate a file upload and it works on File objects.

This is helpful for testing purposes.

Seq.empty[String].toDF()

Yes, it can throw an exception and you can declare that in the signature of the constructor too as shown in the example below:

public class ConstructorTest
{
    public ConstructorTest() throws InterruptedException
    {
        System.out.println("Preparing object....");
        Thread.sleep(1000);
        System.out.println("Object ready");
    }

    public static void main(String ... args)
    {
        try
        {
            ConstructorTest test = new ConstructorTest();
        }
        catch (InterruptedException e)
        {
            System.out.println("Got interrupted...");
        }
    }
}

For newbies, you can extend your partial service class in a separate cs file and add the code the code provided by "imanabidi" to get it integrated

You need either

• A unique index on Title in BookTitle
• An ISBN column in BookCopy and the FK is on both columns

A foreign key needs to uniquely identify the parent row: you currently have no way to do that because Title is not unique.

All you need to do is reverse your ORDER BY. Add or remove DESC to it.

I am sorry, but I must disagree with many of the other answers. I would like to stop this muddled misunderstanding of the definition of declarative programming.

Definition

Referential transparency (RT) of the sub-expressions is the only required attribute of a declarative programming expression, because it is the only attribute which is not shared with imperative programming.

Other cited attributes of declarative programming, derive from this RT. Please click the hyperlink above for the detailed explanation.

Spreadsheet example

Two answers mentioned spreadsheet programming. In the cases where the spreadsheet programming (a.k.a. formulas) does not access mutable global state, then it is declarative programming. This is because the mutable cell values are the monolithic input and output of the main() (the entire program). The new values are not written to the cells after each formula is executed, thus they are not mutable for the life of the declarative program (execution of all the formulas in the spreadsheet). Thus relative to each other, the formulas view these mutable cells as immutable. An RT function is allowed to access immutable global state (and also mutable local state).

Thus the ability to mutate the values in the cells when the program terminates (as an output from main()), does not make them mutable stored values in the context of the rules. The key distinction is the cell values are not updated after each spreadsheet formula is performed, thus the order of performing the formulas does not matter. The cell values are updated after all the declarative formulas have been performed.

This works for me. It should be in your onOptionsItemSelected(MenuItem item) method item.setIcon(R.drawable.your_icon);

Bash's set will parse all output into position parameters.

For instance, with set $(free -h) command, echo $7 will show "Mem:"

Javascript now has a specific built in object called Map, you can call as follows :

   var myMap = new Map()

You can update it with .set :

   myMap.set("key0","value")

This has the advantage of methods you can use to handle look ups, like the boolean .has

  myMap.has("key1"); // evaluates to false 

You can use this before calling .get on your Map object to handle looking up non-existent keys

def split_and_save_df(df, name, size, output_dir):
    """
    Split a df and save each chunk in a different csv file.

    Parameters:
        df : pandas df to be splitted
        name : name to give to the output file
        size : chunk size
        output_dir : directory where to write the divided df
    """
    import os
    for i in range(0, df.shape[0],size):
        start  = i
        end    = min(i+size-1, df.shape[0]) 
        subset = df.loc[start:end] 
        output_path = os.path.join(output_dir,f"{name}_{start}_{end}.csv")
        print(f"Going to write into {output_path}")
        subset.to_csv(output_path)
        output_size = os.stat(output_path).st_size
        print(f"Wrote {output_size} bytes")

It works for me, but some differences:

• I have no welcome-file-list in web.xml
• I have no @RequestMapping at class level.
• And at method level, just @RequestMapping("/")

I know these are no great differences, but I'm pretty sure (I'm not at work now) this is my configuration and it works with Spring MVC 3.0.5.

One more thing. You don't show your dispatcher configuration in web.xml, but maybe you have some preffix. It has to be something like this:

<servlet-mapping>
    <servlet-name>myServletName</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

If this is not your case, you'll need an url-rewrite filter or try the redirect solution.

EDIT: Answering your question, my view resolver configuration is a little different too:

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="/WEB-INF/view/" />
    <property name="suffix" value=".jsp" />
</bean>

If you're allowed to use lambdas from Java 8, you can use the following code sample.

final String text = "1:2:3:4:5";
final List<Integer> list = Arrays.asList(text.split(":")).stream()
  .map(s -> Integer.parseInt(s))
  .collect(Collectors.toList());
System.out.println(list);

No use of external libraries. Plain old new Java!

Make sure that the string is in the following JSON format which is something like this:

{"result":"success","testid":"1"} (with " ") .

If not, then you can add "responsetype => json" in your request params.

Then use json_decode($response,true) to convert it into an array.

Here is a complete example for navigating valid URL on a new tab with focused.

HTML:

<div class="panel">
  <p>
    Enter Url: 
    <input type="text" id="txturl" name="txturl" size="30" class="weburl" />
    &nbsp;&nbsp;    
    <input type="button" id="btnopen"  value="Open Url in New Tab" onclick="openURL();"/>
  </p>
</div>

CSS:

.panel{
  font-size:14px;
}
.panel input{
  border:1px solid #333;
}

JAVASCRIPT:

function isValidURL(url) {
    var RegExp = /(ftp|http|https):\/\/(\w+:{0,1}\w*@)?(\S+)(:[0-9]+)?(\/|\/([\w#!:.?+=&%@!\-\/]))?/;

    if (RegExp.test(url)) {
        return true;
    } else {
        return false;
    }
}

function openURL() {
    var url = document.getElementById("txturl").value.trim();
    if (isValidURL(url)) {
        var myWindow = window.open(url, '_blank');
        myWindow.focus();
        document.getElementById("txturl").value = '';
    } else {
        alert("Please enter valid URL..!");
        return false;
    }
}

I have also created a bin with the solution on http://codebins.com/codes/home/4ldqpbw

I prefer:

highlight ColorColumn ctermbg=gray
set colorcolumn=80

None of the answers will solve your problem permanently. If you go to the path of adding XSD (From Xml menu, select "Create schema"), you will end up having problems with the package manager as it will clean up your packages.config file when you add a new package.

The best solution is just ignore by closing the file when you don't use it.

In 2018:

<input type="number" pattern="\d*">

is working for both Android and iOS.

I tested on Android (^4.2) and iOS (11.3)

you should see this tutorial: https://scotch.io/@micwanyoike/how-to-add-fonts-to-a-react-project

import WebFont from 'webfontloader';

WebFont.load({
  google: {
    families: ['Titillium Web:300,400,700', 'sans-serif']
  }
});

I just tried this method and I can say that it works very well ;)

Something like this should work, calling the ArrayList constructor that takes a Collection:

List theList = new ArrayList(coll);

Ant Runtime

Simply set includeantruntime="false":

<javac includeantruntime="false" ...>...</javac>

If you have to use the javac-task multiple times you might want to consider using PreSetDef to define your own javac-task that always sets includeantruntime="false".

Additional Details

From http://www.coderanch.com/t/503097/tools/warning-includeantruntime-was-not-set:

That's caused by a misfeature introduced in Ant 1.8. Just add an attribute of that name to the javac task, set it to false, and forget it ever happened.

From http://ant.apache.org/manual/Tasks/javac.html:

Whether to include the Ant run-time libraries in the classpath; defaults to yes, unless build.sysclasspath is set. It is usually best to set this to false so the script's behavior is not sensitive to the environment in which it is run.

I've used JMeter. Besides testing the web server you can also test your database backend, messaging services and email servers.

Also check for any long running processes executed from your .NET app against the DB. For example you may be calling a stored procedure or query which does not have enough time to finish which can show in your logs as:

• Execution Timeout Expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

  • This SqlTransaction has completed; it is no longer usable.

Check the command timeout settings Try to run a trace (profiler) and see what is happening on the DB side...

Another one by empty() :

$(this).closest('tr').empty();

I had the error of

No provider for Router

It happens when you try to navigate in any service.ts

this.router.navigate(['/home']); like codes in services cause that error.

You should handle navigating in your components. for example: at login.component

login().subscribe(
        (res) => this.router.navigate(['/home']),
        (error: any) => this.handleError(error));

Annoying errors happens when we are newbie :)

You can remove classes and add classes dynamically

$(document).ready(function(){
    $('#div').removeClass('left').addClass('right');
});

Both console.log("story" + name + "story") and console.log("story", name, "story") works just fine as mentioned in earlier answers.

I will still suggest of having a habit of console.log("story", name, "story"), because, if trying to print the object contents, like json object, having "story" + objectVariable + "story" will convert it into string.

This will have output like : "story" [object Object] "story".

Just a good practice.

You should use @input:

<input @input="handleInput" />

@input fires when user changes input value.

@change fires when user changed value and unfocus input (for example clicked somewhere outside)

You can see the difference here: https://jsfiddle.net/posva/oqe9e8pb/

Expanding on the answers provided here.

You can just do set idx = 1 to set a variable, but that syntax is not recommended because the variable name may clash with a set sub-command. As an example set w=1 would not be valid.

This means that you should prefer the syntax: set variable idx = 1 or set var idx = 1.

Last but not least, you can just use your trusty old print command, since it evaluates an expression. The only difference being that he also prints the result of the expression.

(gdb) p idx = 1
$1 = 1

You can read more about gdb here.

If you want to do it without using a separate variable then

$("#myForm").data('validator').resetForm();

Dim o
Set o = CreateObject("MSXML2.XMLHTTP")
o.open "GET", "http://www.example.com", False
o.send
' o.responseText now holds the response as a string.

Cocoa has couple of methods for this:

in NSDate

– isEqualToDate:  
– earlierDate:  
– laterDate:  
– compare:

When you use - (NSComparisonResult)compare:(NSDate *)anotherDate ,you get back one of these:

The receiver and anotherDate are exactly equal to each other, NSOrderedSame
The receiver is later in time than anotherDate, NSOrderedDescending
The receiver is earlier in time than anotherDate, NSOrderedAscending.

example:

NSDate * now = [NSDate date];
NSDate * mile = [[NSDate alloc] initWithString:@"2001-03-24 10:45:32 +0600"];
NSComparisonResult result = [now compare:mile];

NSLog(@"%@", now);
NSLog(@"%@", mile);

switch (result)
{
    case NSOrderedAscending: NSLog(@"%@ is in future from %@", mile, now); break;
    case NSOrderedDescending: NSLog(@"%@ is in past from %@", mile, now); break;
    case NSOrderedSame: NSLog(@"%@ is the same as %@", mile, now); break;
    default: NSLog(@"erorr dates %@, %@", mile, now); break;
}

[mile release];

If only names of regular files immediately contained within a directory (assume it's ~/dirs) are needed, you can do

find ~/docs -type f -maxdepth 1 > filenames.txt

Error code 2 means "File/Directory not found". In general, you could use the perror function to print a human readable string.

Just index using you ind_pos

ind_pos = [1,5,7]
print (a[ind_pos]) 
[88 85 16]


In [55]: a = [0,88,26,3,48,85,65,16,97,83,91]

In [56]: import numpy as np

In [57]: arr = np.array(a)

In [58]: ind_pos = [1,5,7]

In [59]: arr[ind_pos]
Out[59]: array([88, 85, 16])

Just call fig.tight_layout() as you normally would. (pyplot is just a convenience wrapper. In most cases, you only use it to quickly generate figure and axes objects and then call their methods directly.)

There shouldn't be a difference between the QtAgg backend and the default backend (or if there is, it's a bug).

E.g.

import matplotlib.pyplot as plt

#-- In your case, you'd do something more like:
# from matplotlib.figure import Figure
# fig = Figure()
#-- ...but we want to use it interactive for a quick example, so 
#--    we'll do it this way
fig, axes = plt.subplots(nrows=4, ncols=4)

for i, ax in enumerate(axes.flat, start=1):
    ax.set_title('Test Axes {}'.format(i))
    ax.set_xlabel('X axis')
    ax.set_ylabel('Y axis')

plt.show()

Before Tight Layout

After Tight Layout

import matplotlib.pyplot as plt

fig, axes = plt.subplots(nrows=4, ncols=4)

for i, ax in enumerate(axes.flat, start=1):
    ax.set_title('Test Axes {}'.format(i))
    ax.set_xlabel('X axis')
    ax.set_ylabel('Y axis')

fig.tight_layout()

plt.show()

If you could use something other than 'awk' , then try this instead

echo '1540 "A B"' | cut -d' ' -f2-

-d is a delimiter, -f is the field to cut and with -f2- we intend to cut the 2nd field until end.

The easiest way I found is using Activity Transitions, it is really easy

Override onCreate method in activity you want to run with animation:

@Override
  protected void onCreate(Bundle savedInstanceState) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
      Slide slide = new Slide();
      slide.setSlideEdge(Gravity.RIGHT);

      getWindow().setEnterTransition(slide);
    }
    super.onCreate(savedInstanceState);
  }

Then start it using transitions (instead activity.startActivity(context)):

activity.startActivity(starter, ActivityOptions.makeSceneTransitionAnimation(activity).toBundle());

For closing activity with animation instead using this.finish() use below code:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
      getActivity().finishAfterTransition();
    } else getActivity().finish();

For more information check below links:

Below slightly modified version of @iFreilicht answer, updated to C++14 (usage of make_unique function instead of raw declaration) and added support for std::string arguments (based on Kenny Kerr article)

#include <iostream>
#include <memory>
#include <string>
#include <cstdio>

template <typename T>
T process_arg(T value) noexcept
{
    return value;
}

template <typename T>
T const * process_arg(std::basic_string<T> const & value) noexcept
{
    return value.c_str();
}

template<typename ... Args>
std::string string_format(const std::string& format, Args const & ... args)
{
    const auto fmt = format.c_str();
    const size_t size = std::snprintf(nullptr, 0, fmt, process_arg(args) ...) + 1;
    auto buf = std::make_unique<char[]>(size);
    std::snprintf(buf.get(), size, fmt, process_arg(args) ...);
    auto res = std::string(buf.get(), buf.get() + size - 1);
    return res;
}

int main()
{
    int i = 3;
    float f = 5.f;
    char* s0 = "hello";
    std::string s1 = "world";
    std::cout << string_format("i=%d, f=%f, s=%s %s", i, f, s0, s1) << "\n";
}

Output:

i = 3, f = 5.000000, s = hello world

in SQL 2017 You can do it more easily in the toolbar to the right just hit

the SQL button then its gonna apear the query with the top 200 you edit until the quantity that You want and Execute the query and Done! just Edit

You are iterating trough items in words but you have to iterate through item's length:

words = ['aba', 'xyz', 'xgx', 'dssd', 'sdjh']
c = 0
for i in range(len(words)):
    w1 = words[i]
    if w1[0] == w1[len(w1) - 1]:
      c += 1
    print (c)

In your case i[0] is 'aba' because i is calculated from items in words:

words = ['aba', 'xyz', 'xgx', 'dssd', 'sdjh']
c = 0
for i in words:
print(i)

the output is:

aba

The quick and dirty way I use to export mysql output to a file is

$ mysql <database_name> --tee=<file_path>

and then use the exported output (which you can find in <file_path>) wherever I want.

Note that this is the only way you have in order to avoid databases running using the secure-file-priv option, which prevents the usage of INTO OUTFILE suggested in the previous answers:

ERROR 1290 (HY000): The MySQL server is running with the --secure-file-priv option so it cannot execute this statement

Image.paste does not work as expected when the background image also contains transparency. You need to use real Alpha Compositing.

Pillow 2.0 contains an alpha_composite function that does this.

background = Image.open("test1.png")
foreground = Image.open("test2.png")

Image.alpha_composite(background, foreground).save("test3.png")

EDIT: Both images need to be of the type RGBA. So you need to call convert('RGBA') if they are paletted, etc.. If the background does not have an alpha channel, then you can use the regular paste method (which should be faster).

Late model JAVA has optimizations for + with constant strings, employs a StringBuffer behind the scenes, so you do not want to clutter your code with it.

It points to a JAVA oversight, that it does not resemble ANSI C in the automatic concatenation of double quoted strings with only white space between them, e.g.:

const char usage = "\n"
"Usage: xxxx <options>\n"
"\n"
"Removes your options as designated by the required parameter <options>,\n"
"which must be one of the following strings:\n"
"  love\n"
"  sex\n"
"  drugs\n"
"  rockandroll\n"
"\n" ;

I would love to have a multi-line character array constant where embedded linefeeds are honored, so I can present the block without any clutter, e.g.:

String Query = "
SELECT
    some_column,
    another column
  FROM
      one_table a
    JOIN
      another_table b
    ON    a.id = b.id
      AND a.role_code = b.role_code
  WHERE a.dept = 'sales'
    AND b.sales_quote > 1000
  Order BY 1, 2
" ;

To get this, one needs to beat on the JAVA gods.

You can create a symbolic link with a shorter directory. First open command line for example by Shift + RightClick in your desired folder with a shorter path (you may have to run it as administrator).

Then type with relative or absolute paths:

mklink ShortPath\To\YourLinkedSolution C:\Path\To\Your\Solution /D

And then start the Solution from the shorter path. The advantage here is: You don't have to move anything.

In the first line of your JS code:

select.addEventListener('change', getSelection(this), false);

you're invoking getSelection by placing (this) behind the function reference. That is most likely not what you want, because you're now passing the return value of that call to addEventListener, instead of a reference to the actual function itself.

In a function invoked by addEventListener the value for this will automatically be set to the object the listener is attached to, productLineSelect in this case.

If that is what you want, you can just pass the function reference and this will in this example be select in invocations from addEventListener:

select.addEventListener('change', getSelection, false);

If that is not what you want, you'd best bind your value for this to the function you're passing to addEventListener:

var thisArg = { custom: 'object' };
select.addEventListener('change', getSelection.bind(thisArg), false);

The .bind part is also a call, but this call just returns the same function we're calling bind on, with the value for this inside that function scope fixed to thisArg, effectively overriding the dynamic nature of this-binding.

To get to your actual question: "How to pass parameters to function in addEventListener?"

You would have to use an additional function definition:

var globalVar = 'global';

productLineSelect.addEventListener('change', function(event) {
    var localVar = 'local';
    getSelection(event, this, globalVar, localVar);
}, false);

Now we pass the event object, a reference to the value of this inside the callback of addEventListener, a variable defined and initialised inside that callback, and a variable from outside the entire addEventListener call to your own getSelection function.

We also might again have an object of our choice to be this inside the outer callback:

var thisArg = { custom: 'object' };
var globalVar = 'global';

productLineSelect.addEventListener('change', function(event) {
    var localVar = 'local';
    getSelection(event, this, globalVar, localVar);
}.bind(thisArg), false);

You have to put a g at the end, it stands for "global":

echo dog dog dos | sed -r 's:dog:log:g'
                                     ^

i feel above logics for hover is incorrect. it just inverse when mouse hovers. i have used below code. it seems to work perfectly alright.

<div @mouseover="upHere = true" @mouseleave="upHere = false" >
    <h2> Something Something </h2>
    <some-component v-show="upHere"></some-component>
</div>

on vue instance

data : {
    upHere : false
}

Hope that helps

You shouldn’t use <h1><a name="foo"/>Foo Title</h1> in any flavor of HTML served as text/html, because the XML empty element syntax isn’t supported in text/html. However, <h1><a name="foo">Foo Title</a></h1> is OK in HTML4. It is not valid in HTML5 as currently drafted.

<h1 id="foo">Foo Title</h1> is OK in both HTML4 and HTML5. This won’t work in Netscape 4, but you’ll probably use a dozen other features that don’t work in Netscape 4.

I needed to make report for a catering firm which serves lunches for various clients. In other words, catering may have on or more firms which take orders from catering, and it must know how many lunches it must produce every single day for all it's clients !

Just to notice, I didn't use sorting, in order not to over complicate this example.

This is my code :

@Test
public void test_2() throws Exception {
    Firm catering = DS.firm().get(1);
    LocalDateTime ldtFrom = LocalDateTime.of(2017, Month.JANUARY, 1, 0, 0);
    LocalDateTime ldtTo = LocalDateTime.of(2017, Month.MAY, 2, 0, 0);
    Date dFrom = Date.from(ldtFrom.atZone(ZoneId.systemDefault()).toInstant());
    Date dTo = Date.from(ldtTo.atZone(ZoneId.systemDefault()).toInstant());

    List<PersonOrders> LON = DS.firm().getAllOrders(catering, dFrom, dTo, false);
    Map<Object, Long> M = LON.stream().collect(
            Collectors.groupingBy(p
                    -> Arrays.asList(p.getDatum(), p.getPerson().getIdfirm(), p.getIdProduct()),
                    Collectors.counting()));

    for (Map.Entry<Object, Long> e : M.entrySet()) {
        Object key = e.getKey();
        Long value = e.getValue();
        System.err.println(String.format("Client firm :%s, total: %d", key, value));
    }
}

1. The class Date/Timestamp represents a specific instant in time, with millisecond precision, since January 1, 1970, 00:00:00 GMT. So this time difference (from epoch to current time) will be same in all computers across the world with irrespective of Timezone.

2. Date/Timestamp doesn't know about the given time is on which timezone.

3. If we want the time based on timezone we should go for the Calendar or SimpleDateFormat classes in java.

4. If you try to print a Date/Timestamp object using toString(), it will convert and print the time with the default timezone of your machine.

5. So we can say (Date/Timestamp).getTime() object will always have UTC (time in milliseconds)

6. To conclude Date.getTime() will give UTC time, but toString() is on locale specific timezone, not UTC.

Now how will I create/change time on specified timezone?

The below code gives you a date (time in milliseconds) with specified timezones. The only problem here is you have to give date in string format.

   DateFormat dateFormat = new SimpleDateFormat("yyyyMMdd HH:mm:ss");
   dateFormatLocal.setTimeZone(timeZone);
   java.util.Date parsedDate = dateFormatLocal.parse(date);

Use dateFormat.format for taking input Date (which is always UTC), timezone and return date as String.

How to store UTC/GMT time in DB:

If you print the parsedDate object, the time will be in default timezone. But you can store the UTC time in DB like below.

        Calendar calGMT = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
        Timestamp tsSchedStartTime = new Timestamp (parsedDate.getTime());
        if (tsSchedStartTime != null) {
            stmt.setTimestamp(11, tsSchedStartTime, calGMT );
        } else {
            stmt.setNull(11, java.sql.Types.DATE);
        }

You can try this simple way for combining columns:

select some_other_column,first_name || ' ' || last_name AS First_name from customer;

It might be late but I just thought I should share for the case where you are required to do it manually (show working - haha) OR when you need all elements to appear as many times as possible or when you also need it to be unique.

Kindly note that tests have also been written for it.

Fortes is right, thank you.

When you have a shared hosting it is usual to obtain an 500 server error.

I have a website with Joomla and I added to the index.php:

ini_set('display_errors','off');

The error line showed in my website disappeared.

There's a handy function, oidvectortypes, that makes this a lot easier.

SELECT format('%I.%I(%s)', ns.nspname, p.proname, oidvectortypes(p.proargtypes)) 
FROM pg_proc p INNER JOIN pg_namespace ns ON (p.pronamespace = ns.oid)
WHERE ns.nspname = 'my_namespace';

Credit to Leo Hsu and Regina Obe at Postgres Online for pointing out oidvectortypes. I wrote similar functions before, but used complex nested expressions that this function gets rid of the need for.

See related answer.

(edit in 2016)

Summarizing typical report options:

-- Compact:
SELECT format('%I.%I(%s)', ns.nspname, p.proname, oidvectortypes(p.proargtypes))

-- With result data type: 
SELECT format(
       '%I.%I(%s)=%s', 
       ns.nspname, p.proname, oidvectortypes(p.proargtypes),
       pg_get_function_result(p.oid)
)

-- With complete argument description: 
SELECT format('%I.%I(%s)', ns.nspname, p.proname, pg_get_function_arguments(p.oid))

-- ... and mixing it.

-- All with the same FROM clause:
FROM pg_proc p INNER JOIN pg_namespace ns ON (p.pronamespace = ns.oid)
WHERE ns.nspname = 'my_namespace';

NOTICE: use p.proname||'_'||p.oid AS specific_name to obtain unique names, or to JOIN with information_schema tables — see routines and parameters at @RuddZwolinski's answer.

The function's OID (see pg_catalog.pg_proc) and the function's specific_name (see information_schema.routines) are the main reference options to functions. Below, some useful functions in reporting and other contexts.

Thanks for the idea of breaking down a formula Werner!

Using Alt+Enter allows one to put each bit of a complex substitute formula on separate lines: they become easier to follow and automatically line themselves up when Enter is pressed.

Just make sure you have enough end statements to match the number of substitute( lines either side of the cell reference.

As in this example:

=
substitute(
substitute(
substitute(
substitute(
B11
,"(","")
,")","")
,"[","")
,"]","")

becomes:

=
SUBSTITUTE(
SUBSTITUTE(
SUBSTITUTE(
SUBSTITUTE(B12,"(",""),")",""),"[",""),"]","")

which works fine as is, but one can always delete the extra paragraphs manually:

=SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(B12,"(",""),")",""),"[",""),"]","")

Name > substitute()

Is the snippet you posted just a sample to show what you are trying to do?

The reason I ask is that you've named a method increment, but you seem to be using that to set the value of a text label, rather than incrementing a value.

If you are trying to do something more complicated - such as setting an integer value and having the label display this value, you could consider using bindings. e.g

You declare a property count and your increment action sets this value to whatever, and then in IB, you bind the label's text to the value of count. As long as you follow Key Value Coding (KVC) with count, you don't have to write any code to update the label's display. And from a design perspective you've got looser coupling.

First you need to use Dispatcher.Invoke to change the UI from another thread and to do that from another class, you can use events.
Then you can register to that event(s) in the main class and Dispatch the changes to the UI and in the calculation class you throw the event when you want to notify the UI:

class MainWindow : Window
{
    private void startCalc()
    {
        //your code
        CalcClass calc = new CalcClass();
        calc.ProgressUpdate += (s, e) => {
            Dispatcher.Invoke((Action)delegate() { /* update UI */ });
        };
        Thread calcthread = new Thread(new ParameterizedThreadStart(calc.testMethod));
        calcthread.Start(input);
    }
}

class CalcClass
{
    public event EventHandler ProgressUpdate;

    public void testMethod(object input)
    {
        //part 1
        if(ProgressUpdate != null)
            ProgressUpdate(this, new YourEventArgs(status));
        //part 2
    }
}

UPDATE:
As it seems this is still an often visited question and answer I want to update this answer with how I would do it now (with .NET 4.5) - this is a little longer as I will show some different possibilities:

class MainWindow : Window
{
    Task calcTask = null;

    void buttonStartCalc_Clicked(object sender, EventArgs e) { StartCalc(); } // #1
    async void buttonDoCalc_Clicked(object sender, EventArgs e) // #2
    {
        await CalcAsync(); // #2
    }

    void StartCalc()
    {
        var calc = PrepareCalc();
        calcTask = Task.Run(() => calc.TestMethod(input)); // #3
    }
    Task CalcAsync()
    {
        var calc = PrepareCalc();
        return Task.Run(() => calc.TestMethod(input)); // #4
    }
    CalcClass PrepareCalc()
    {
        //your code
        var calc = new CalcClass();
        calc.ProgressUpdate += (s, e) => Dispatcher.Invoke((Action)delegate()
            {
                // update UI
            });
        return calc;
    }
}

class CalcClass
{
    public event EventHandler<EventArgs<YourStatus>> ProgressUpdate; // #5

    public TestMethod(InputValues input)
    {
        //part 1
        ProgressUpdate.Raise(this, status); // #6 - status is of type YourStatus
        //part 2
    }
}

static class EventExtensions
{
    public static void Raise<T>(this EventHandler<EventArgs<T>> theEvent,
                                object sender, T args)
    {
        if (theEvent != null)
            theEvent(sender, new EventArgs<T>(args));
    }
}

@1) How to start the "synchronous" calculations and run them in the background

@2) How to start it "asynchronous" and "await it": Here the calculation is executed and completed before the method returns, but because of the async/await the UI is not blocked (BTW: such event handlers are the only valid usages of async void as the event handler must return void - use async Task in all other cases)

@3) Instead of a new Thread we now use a Task. To later be able to check its (successfull) completion we save it in the global calcTask member. In the background this also starts a new thread and runs the action there, but it is much easier to handle and has some other benefits.

@4) Here we also start the action, but this time we return the task, so the "async event handler" can "await it". We could also create async Task CalcAsync() and then await Task.Run(() => calc.TestMethod(input)).ConfigureAwait(false); (FYI: the ConfigureAwait(false) is to avoid deadlocks, you should read up on this if you use async/await as it would be to much to explain here) which would result in the same workflow, but as the Task.Run is the only "awaitable operation" and is the last one we can simply return the task and save one context switch, which saves some execution time.

@5) Here I now use a "strongly typed generic event" so we can pass and receive our "status object" easily

@6) Here I use the extension defined below, which (aside from ease of use) solve the possible race condition in the old example. There it could have happened that the event got null after the if-check, but before the call if the event handler was removed in another thread at just that moment. This can't happen here, as the extensions gets a "copy" of the event delegate and in the same situation the handler is still registered inside the Raise method.

This creates backup files. E.g. sed -i -e 's/hello/hello world/' testfile for me, creates a backup file, testfile-e, in the same dir.

NSString *htmlString = @"<html>bla bla</html>";
NSString *stringWithoutHTML = [hstmString stringByReplacingOccurrencesOfRegex:myregex withString:@""];

don't forget to include this in your code : #import "RegexKitLite.h" here is the link to download this API : http://regexkit.sourceforge.net/#Downloads

You could also use

ImageIcon background = new ImageIcon("Background/background.png");
JLabel label = new JLabel();
label.setBounds(0, 0, x, y);
label.setIcon(background);

JPanel panel = new JPanel();
panel.setLayout(null);
panel.add(label);

if your working with a absolut value as layout.

You can follow this approach:

void addOrUpdate(Dictionary<int, int> dic, int key, int newValue)
{
    int val;
    if (dic.TryGetValue(key, out val))
    {
        // yay, value exists!
        dic[key] = val + newValue;
    }
    else
    {
        // darn, lets add the value
        dic.Add(key, newValue);
    }
}

The edge you get here is that you check and get the value of corresponding key in just 1 access to the dictionary. If you use ContainsKey to check the existance and update the value using dic[key] = val + newValue; then you are accessing the dictionary twice.

Do you have an index defined over the Status column and MemberType column?

I believe you want <= 90

lower(a) 
int a; 
{
    if ((a >= 65) && (a <= 90))
        a = a + 32; 
    return a;  
}

Although tolower would probably just save you the hassle unless you wanted to do this yourself. http://www.cplusplus.com/reference/cctype/tolower/

In order to solve this I made sure that I upgraded to the newest MVC version using NuGet and Package Manager Console.

Install-Package Microsoft.AspNet.Mvc -Version 5.2.4

Then upgraded to the latest Razor version

Install-Package Microsoft.AspNet.Razor -Version 3.2.4

Then I changed all the web.config files to reflect the change. As you will see below:

In the main web.config file, make sure that the webpages:version is correct. This is where it can be found (ignore the other keys):

<configuration>
 <appSettings>
   <add key="webpages:Version" value="3.0.0.0"/>
   <add key="ClientValidationEnabled" value="true"/>
   <add key="UnobtrusiveJavaScriptEnabled" value="true"/>
 </appSettings>
</configuration>

Then look for the other versions listed in the assemblies, check the version of the assembly against the version of the library listed in your project references! You may not need all of these.

<system.web>
    <compilation debug="true" targetFramework="4.6">
        <assemblies>
            <add assembly="System.Web.Abstractions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
            <add assembly="System.Web.Helpers, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
            <add assembly="System.Web.Routing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
            <add assembly="System.Web.Mvc, Version=5.2.4.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
            <add assembly="System.Web.WebPages, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
        </assemblies>
    </compilation>
</system.web>

Runtime assemblyBinding should show the "newversion" as well, see where it reads NewVersion 5.2.4.0? But also check all the other versions.

<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
       <dependentAssembly>
        <assemblyIdentity name="System.Web.Razor" publicKeyToken="31bf3856ad364e35" culture="neutral"/>
        <bindingRedirect oldVersion="0.0.0.0-3.0.0.0" newVersion="3.0.0.0"/>
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="System.Web.Helpers" publicKeyToken="31bf3856ad364e35"/>
        <bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="3.0.0.0"/>
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="System.Web.WebPages" publicKeyToken="31bf3856ad364e35"/>
        <bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="3.0.0.0"/>
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35"/>
        <bindingRedirect oldVersion="1.0.0.0-5.2.4.0" newVersion="5.2.4.0"/>
      </dependentAssembly>
    </assemblyBinding>
  </runtime>

THEN in the Views Web.Config section, make sure that Razor is the correct version:

<configuration>
  <configSections>
    <sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
      <section name="host" type="System.Web.WebPages.Razor.Configuration.HostSection, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
      <section name="pages" type="System.Web.WebPages.Razor.Configuration.RazorPagesSection, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
    </sectionGroup>
  </configSections>
<configuration>

And Lastlt there is the Pages section of the Views Web.Config

    <pages
    validateRequest="false"
    pageParserFilterType="System.Web.Mvc.ViewTypeParserFilter, System.Web.Mvc, Version=5.2.4.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"
    pageBaseType="System.Web.Mvc.ViewPage, System.Web.Mvc, Version=5.2.4.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"
    userControlBaseType="System.Web.Mvc.ViewUserControl, System.Web.Mvc, Version=5.2.4.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
      <controls>
        <add assembly="System.Web.Mvc, Version=5.2.4.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" namespace="System.Web.Mvc" tagPrefix="mvc" />
      </controls>
    </pages>

You are trying to return an object. Because there is no good way to represent an object as a string, the object's .toString() value is automatically set as "[object Object]".

My problem too got fixed which i was getting on STS, just closed all the project's including the server on the project explorer, restarted ide, that's it.

ES2015:

let el = document.getElementById("el");
let handler =()=> console.log("changed");
['change', 'keyup', 'cut'].forEach(event => el.addEventListener(event, handler));

Tagging of the image isn't supported inside the Dockerfile. This needs to be done in your build command. As a workaround, you can do the build with a docker-compose.yml that identifies the target image name and then run a docker-compose build. A sample docker-compose.yml would look like

version: '2'

services:
  man:
    build: .
    image: dude/man:v2

That said, there's a push against doing the build with compose since that doesn't work with swarm mode deploys. So you're back to running the command as you've given in your question:

docker build -t dude/man:v2 .

Personally, I tend to build with a small shell script in my folder (build.sh) which passes any args and includes the name of the image there to save typing. And for production, the build is handled by a ci/cd server that has the image name inside the pipeline script.

If you are using SqlServer the distinct keyword should work for you. (Not sure about other databases)

declare @t table (a int , b int)

insert into @t (a,b) select 1, 1
insert into @t (a,b) select 1, 2
insert into @t (a,b) select 1, 1

select distinct * from @t

results in

a b
1 1
1 2

If you're using Rails and ActiveAdmin, this is going to be your problem: https://github.com/seyhunak/twitter-bootstrap-rails/issues/450 Basically, a conflict with active_admin.js

This is the solution: https://stackoverflow.com/a/11745446/264084 (Karen's answer) tldr: Move active_admin assets into the "vendor" directory.

The trick is a second .box-inner inside, which is larger in width than the original .box, and the box-shadow is applied to that.

Then, added more padding to the .text to make up for the added width.

This is how the logic looks:

And here's how it's done in CSS:

Use max width for .inner-box to not cause .box to get wider, and overflow to make sure the remaining is clipped:

.box {
    max-width: 100% !important;
    overflow: hidden;
}

110% is wider than the parent which is 100% in a child's context (should be the same when the parent .box has a fixed width, for example). Negative margins make up for the width and cause the element to be centered (instead of only the right part hiding):

.box-inner {
    width: 110%;
    margin-left:-5%;
    margin-right: -5%;
    -webkit-box-shadow: inset 0px 5px 10px 1px #000000;
    box-shadow: inset 0px 5px 10px 1px #000000;
}

And add some padding on the X axis to make up for the wider .inner-box:

.text {
    padding: 20px 40px;
}

Here's a working Fiddle.

If you inspect the Fiddle, you'll see:

If each line is a fixed length then you can open a Stream around it, seek (bytes per line) * n into the file and read your line from there.

using( Stream stream = File.Open(fileName, FileMode.Open) )
{
    stream.Seek(bytesPerLine * (myLine - 1), SeekOrigin.Begin);
    using( StreamReader reader = new StreamReader(stream) )
    {
        string line = reader.ReadLine();
    }
}

Alternatively you could just use the StreamReader to read lines until you found the one you wanted. That way's slower but still an improvement over reading every single line.

using( Stream stream = File.Open(fileName, FileMode.Open) )
{
    using( StreamReader reader = new StreamReader(fileStream) )
    {
        string line = null;
        for( int i = 0; i < myLineNumber; ++i )
        {
            line = reader.ReadLine();
        }
    }
}

Concatenate the string separating the slash and the word script in this way.

Response.Write("<script language='javascript'>alert('Especifique Usuario y Contraseña');</" + "script>");

How about writing a custom attribute:

public class LocalizedDisplayNameAttribute: DisplayNameAttribute
{
    public LocalizedDisplayNameAttribute(string resourceId) 
        : base(GetMessageFromResource(resourceId))
    { }

    private static string GetMessageFromResource(string resourceId)
    {
        // TODO: Return the string from the resource file
    }
}

which could be used like this:

public class MyModel 
{
    [Required]
    [LocalizedDisplayName("labelForName")]
    public string Name { get; set; }
}

Also check to see if you are missing the www in the url which was on my case

i was testing on http://www.mywebsite.com and in the facebook app i had set http://mywebsite.com

In spark version >= 3 you can convert pandas dataframes to pyspark dataframe in one line

use spark.createDataFrame(pandasDF)

dataset = pd.read_csv("data/AS/test_v2.csv")

sparkDf = spark.createDataFrame(dataset);

if you are confused about spark session variable, spark session is as follows

sc = SparkContext.getOrCreate(SparkConf().setMaster("local[*]"))

spark = SparkSession \
    .builder \
    .getOrCreate()

Setting RetainSameConnection property to True for Excel manager Worked for me .

If you need the entire table structure (not just the basic data layout), use Task>Script Table As>Create To>New Query Window and run in your new database. Then you can copy the data at your leisure.

Also, this might help finding the actual location the btsnoop_hci.log is being saved:

adb shell "cat /etc/bluetooth/bt_stack.conf | grep FileName"

Actually, it's easier than you think. In any browsers press F12 to bring up the debug console. This works for IE, Firefox, and Chrome. Not sure about Opera. Then comment out the CSS in the element windows. That's it.

Thanks to DroidT, I made this:

I realize that if the Fragment does not execute onCreateView(), its view is not instantiated. So, if the fragment on back stack did not create its views, I save the last stored state, otherwise I build my own bundle with the data I want to save/restore.

1) Extend this class:

import android.os.Bundle;
import android.support.v4.app.Fragment;

public abstract class StatefulFragment extends Fragment {

    private Bundle savedState;
    private boolean saved;
    private static final String _FRAGMENT_STATE = "FRAGMENT_STATE";

    @Override
    public void onSaveInstanceState(Bundle state) {
        if (getView() == null) {
            state.putBundle(_FRAGMENT_STATE, savedState);
        } else {
            Bundle bundle = saved ? savedState : getStateToSave();

            state.putBundle(_FRAGMENT_STATE, bundle);
        }

        saved = false;

        super.onSaveInstanceState(state);
    }

    @Override
    public void onCreate(Bundle state) {
        super.onCreate(state);

        if (state != null) {
            savedState = state.getBundle(_FRAGMENT_STATE);
        }
    }

    @Override
    public void onDestroyView() {
        savedState = getStateToSave();
        saved = true;

        super.onDestroyView();
    }

    protected Bundle getSavedState() {
        return savedState;
    }

    protected abstract boolean hasSavedState();

    protected abstract Bundle getStateToSave();

}

2) In your Fragment, you must have this:

@Override
protected boolean hasSavedState() {
    Bundle state = getSavedState();

    if (state == null) {
        return false;
    }

    //restore your data here

    return true;
}

3) For example, you can call hasSavedState in onActivityCreated:

@Override
public void onActivityCreated(Bundle state) {
    super.onActivityCreated(state);

    if (hasSavedState()) {
        return;
    }

    //your code here
}

I absolutely hate and despise working for free for Microsoft, given how after all those billions of dollars they STILL do not to have proper guides about stuff like this with screenshots on their damn website.

Anyways, here is a quick guide in Word 2010, using Notepad++ for syntax coloring, and a TextBox which can be captioned:

1. Choose Insert / Text Box / Simple Text Box
   
2. A default text box is inserted
   
3. Switch to NPP, choose the language for syntax coloring of your code, go to Plugins / NPPExport / Copy RTF to clipboard
   
4. Switch back to word, and paste into the text box - it may be too small ...
   
5. ... so you may have to change its size
   
6. Having selected the text box, right-click on it, then choose Insert Caption ...
   
7. In the Caption menu, if you don't have one already, click New Label, and set the new label to "Code", click OK ...
   
8. ... then in the Caption dialog, switch the label to Code, and hit OK
   
9. Finally, type your caption in the newly created caption box
   

My two suggestions:

1. Chrome's Postman plugin + the Postman Interceptor Plugin. More Info: Postman Capturing Requests Docs

2. If you're on Windows then Telerik's Fiddler is an option. It has a composer option to replay http requests, and it's free.

Lots of pretty terrible answers here so I'll add mine (including test program):

#include <string>
#include <iostream>
#include <cstddef>

template<typename StringFunction>
void splitString(const std::string &str, char delimiter, StringFunction f) {
  std::size_t from = 0;
  for (std::size_t i = 0; i < str.size(); ++i) {
    if (str[i] == delimiter) {
      f(str, from, i);
      from = i + 1;
    }
  }
  if (from <= str.size())
    f(str, from, str.size());
}


int main(int argc, char* argv[]) {
    if (argc != 2)
        return 1;

    splitString(argv[1], ',', [](const std::string &s, std::size_t from, std::size_t to) {
        std::cout << "`" << s.substr(from, to - from) << "`\n";
    });

    return 0;
}

Nice properties:

• No dependencies (e.g. boost)
• Not an insane one-liner
• Easy to understand (I hope)
• Handles spaces perfectly fine
• Doesn't allocate splits if you don't want to, e.g. you can process them with a lambda as shown.
• Doesn't add characters one at a time - should be fast.
• If using C++17 you could change it to use a std::stringview and then it won't do any allocations and should be extremely fast.

Some design choices you may wish to change:

• Empty entries are not ignored.
• An empty string will call f() once.

Example inputs and outputs:

""      ->   {""}
","     ->   {"", ""}
"1,"    ->   {"1", ""}
"1"     ->   {"1"}
" "     ->   {" "}
"1, 2," ->   {"1", " 2", ""}
" ,, "  ->   {" ", "", " "}

Ummm... an inner class IS a nested class... do you mean anonymous class and inner class?

Edit: If you actually meant inner vs anonymous... an inner class is just a class defined within a class such as:

public class A {
    public class B {
    }
}

Whereas an anonymous class is an extension of a class defined anonymously, so no actual "class is defined, as in:

public class A {
}

A anon = new A() { /* you could change behavior of A here */ };

Further Edit:

Wikipedia claims there is a difference in Java, but I've been working with Java for 8 years, and it's the first I heard such a distinction... not to mention there are no references there to back up the claim... bottom line, an inner class is a class defined within a class (static or not), and nested is just another term to mean the same thing.

There is a subtle difference between static and non-static nested class... basically non-static inner classes have implicit access to instance fields and methods of the enclosing class (thus they cannot be constructed in a static context, it will be a compiler error). Static nested classes, on the other hand, don't have implicit access to instance fields and methods, and CAN be constructed in a static context.

There are many possibilities to do this in R. Here are some of them:

df <- read.table(header = TRUE, text = 'Gene   Value
A      12
A      10
B      3
B      5
B      6
C      1
D      3
D      4')

# aggregate
aggregate(df$Value, by = list(df$Gene), max)
aggregate(Value ~ Gene, data = df, max)

# tapply
tapply(df$Value, df$Gene, max)

# split + lapply
lapply(split(df, df$Gene), function(y) max(y$Value))

# plyr
require(plyr)
ddply(df, .(Gene), summarise, Value = max(Value))

# dplyr
require(dplyr)
df %>% group_by(Gene) %>% summarise(Value = max(Value))

# data.table
require(data.table)
dt <- data.table(df)
dt[ , max(Value), by = Gene]

# doBy
require(doBy)
summaryBy(Value~Gene, data = df, FUN = max)

# sqldf
require(sqldf)
sqldf("select Gene, max(Value) as Value from df group by Gene", drv = 'SQLite')

# ave
df[as.logical(ave(df$Value, df$Gene, FUN = function(x) x == max(x))),]

You asked to be able to run something like npm start 8080. This is possible without needing to modify script.js or configuration files as follows.

For example, in your "scripts" JSON value, include--

"start": "node ./script.js server $PORT"

And then from the command-line:

$ PORT=8080 npm start

I have confirmed that this works using bash and npm 1.4.23. Note that this work-around does not require GitHub npm issue #3494 to be resolved.

To get the namespace in its namespace format, e.g. {myNameSpace}, you can do the following:

root = tree.getroot()
ns = re.match(r'{.*}', root.tag).group(0)

This way, you can use it later on in your code to find nodes, e.g using string interpolation (Python 3).

link = root.find(f"{ns}link")

you could do this, if you want to use the old syntax (or don't want to rewrite every template)

@for $i from 1 through $grid-columns {
  @include media-breakpoint-up(xs) {
    .col-xs-#{$i} {
      @include make-col-ready();
      @include make-col($i);
    }
  }
}

Try this:

var label = $('#currentMonth').text()

If the XML is well formed then you can convert it to Document. By using the XPath you can get the XML Elements.

String xml = "<stackusers><name>Yash</name><age>30</age></stackusers>";

Form XML-String Create Document and find the elements using its XML-Path.

Document doc = getDocument(xml, true);

    public static Document getDocument(String xmlData, boolean isXMLData) throws Exception {
        DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
        dbFactory.setNamespaceAware(true);
        dbFactory.setIgnoringComments(true);
        DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
        Document doc;
        if (isXMLData) {
            InputSource ips = new org.xml.sax.InputSource(new StringReader(xmlData));
            doc = dBuilder.parse(ips);
        } else {
            doc = dBuilder.parse( new File(xmlData) );
        }
        return doc;
    }

Use org.apache.xpath.XPathAPI to get Node or NodeList.

System.out.println("XPathAPI:"+getNodeValue(doc, "/stackusers/age/text()"));

NodeList nodeList = getNodeList(doc, "/stackusers");
System.out.println("XPathAPI NodeList:"+ getXmlContentAsString(nodeList));
System.out.println("XPathAPI NodeList:"+ getXmlContentAsString(nodeList.item(0)));

    public static String getNodeValue(Document doc, String xpathExpression) throws Exception {
        Node node = org.apache.xpath.XPathAPI.selectSingleNode(doc, xpathExpression);
        String nodeValue = node.getNodeValue();
        return nodeValue;
    }
    public static NodeList getNodeList(Document doc, String xpathExpression) throws Exception {
        NodeList result = org.apache.xpath.XPathAPI.selectNodeList(doc, xpathExpression);
        return result;
    }

Using javax.xml.xpath.XPathFactory

System.out.println("javax.xml.xpath.XPathFactory:"+getXPathFactoryValue(doc, "/stackusers/age"));

    static XPath xpath = javax.xml.xpath.XPathFactory.newInstance().newXPath();
    public static String getXPathFactoryValue(Document doc, String xpathExpression) throws XPathExpressionException, TransformerException, IOException {
        Node node = (Node) xpath.evaluate(xpathExpression, doc, XPathConstants.NODE);
        String nodeStr = getXmlContentAsString(node);
        return nodeStr;
    }

Using Document Element.

System.out.println("DocumentElementText:"+getDocumentElementText(doc, "age"));

    public static String getDocumentElementText(Document doc, String elementName) {
        return doc.getElementsByTagName(elementName).item(0).getTextContent();
    }

Get value in between two strings.

String nodeVlaue = org.apache.commons.lang.StringUtils.substringBetween(xml, "<age>", "</age>");
System.out.println("StringUtils.substringBetween():"+nodeVlaue);

Full Example:

public static void main(String[] args) throws Exception {
    String xml = "<stackusers><name>Yash</name><age>30</age></stackusers>";
    Document doc = getDocument(xml, true);
    
    String nodeVlaue = org.apache.commons.lang.StringUtils.substringBetween(xml, "<age>", "</age>");
    System.out.println("StringUtils.substringBetween():"+nodeVlaue);
    
    System.out.println("DocumentElementText:"+getDocumentElementText(doc, "age"));
    System.out.println("javax.xml.xpath.XPathFactory:"+getXPathFactoryValue(doc, "/stackusers/age"));
    
    System.out.println("XPathAPI:"+getNodeValue(doc, "/stackusers/age/text()"));
    NodeList nodeList = getNodeList(doc, "/stackusers");
    System.out.println("XPathAPI NodeList:"+ getXmlContentAsString(nodeList));
    System.out.println("XPathAPI NodeList:"+ getXmlContentAsString(nodeList.item(0)));
}
public static String getXmlContentAsString(Node node) throws TransformerException, IOException {
    StringBuilder stringBuilder = new StringBuilder();
    NodeList childNodes = node.getChildNodes();
    int length = childNodes.getLength();
    for (int i = 0; i < length; i++) {
        stringBuilder.append( toString(childNodes.item(i), true) );
    }
    return stringBuilder.toString();
}

OutPut:

StringUtils.substringBetween():30
DocumentElementText:30
javax.xml.xpath.XPathFactory:30
XPathAPI:30
XPathAPI NodeList:<stackusers>
   <name>Yash</name>
   <age>30</age>
</stackusers>
XPathAPI NodeList:<name>Yash</name><age>30</age>

If you want happen to be using LESS it can be achieved like so:

li {
    .glyphicon-ok();

    &:before {            
        .glyphicon();            
        margin-left:-25px;
       float:left;
    }
}

This works best:

git fetch origin specific_commit
git checkout -b temp FETCH_HEAD

name "temp" whatever you want...this branch might be orphaned though

An easy way to get the max and min value in an array is as follows. This has been explained at get max & min values in array

var myarray = [5,8,2,4,11,7,3];
// Function to get the Max value in Array
Array.max = function( array ){
return Math.max.apply( Math, array );
};

// Function to get the Min value in Array
Array.min = function( array ){
return Math.min.apply( Math, array );
};
// Usage 
alert(Array.max(myarray));
alert(Array.min(myarray));

You can use shFlags.

It gives you the option to define: DEFINE_bool

Example:

DEFINE_bool(big_menu, true, "Include 'advanced' options in the menu listing");

From the command line you can define:

sh script.sh --bigmenu
sh script.sh --nobigmenu # False

With Android Studio 2.3(AS) the project works fine and i can able to run the App. After updating the AS to Android Studio 3.0. i too got the error as below for libraries and build types.

Unable to resolve dependency for ':app@dexOptions/compileClasspath': Could not resolve project : library_Name.

Unable to resolve dependency for ':app@release/compileClasspath': Could not resolve project : library_Name.

To Solve the issue, simply.

What ever the

buildTypes{
          debug{ ... }
          release{ ... }
    }

you have in your (app) build.gradle file, You have to include all the buildTypes{ } with same names as like

buildTypes{
      debug{ ... }
      release{ ... }
}

in to build.gradle files of All libraries/modules included in project.

clean and rebuild the project, the issue will be fixed.

Still issue not fixed, update the gradle-wrapper.properties to

distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip

As per the docs:

You can set annotation processor argument (room.schemaLocation) to tell Room to export the schema into a folder. Even though it is not mandatory, it is a good practice to have version history in your codebase and you should commit that file into your version control system (but don't ship it with your app!).

So if you don't need to check the schema and you want to get rid of the warning, just add exportSchema = false to your RoomDatabase, as follows.

@Database(entities = { YourEntity.class }, version = 1, exportSchema = false)
public abstract class AppDatabase extends RoomDatabase {
   //...
}

If you follow @mikejonesguy answer below, you will follow the good practice mentioned in the docs :). Basically you will get a .json file in your ../app/schemas/ folder. And it looks something like this:

{
  "formatVersion": 1,
  "database": {
    "version": 1,
    "identityHash": "53db508c5248423325bd5393a1c88c03",
    "entities": [
      {
        "tableName": "sms_table",
        "createSql": "CREATE TABLE IF NOT EXISTS `${TABLE_NAME}` (`id` INTEGER PRIMARY KEY AUTOINCREMENT, `message` TEXT, `date` INTEGER, `client_id` INTEGER)",
        "fields": [
          {
            "fieldPath": "id",
            "columnName": "id",
            "affinity": "INTEGER"
          },
          {
            "fieldPath": "message",
            "columnName": "message",
            "affinity": "TEXT"
          },
          {
            "fieldPath": "date",
            "columnName": "date",
            "affinity": "INTEGER"
          },
          {
            "fieldPath": "clientId",
            "columnName": "client_id",
            "affinity": "INTEGER"
          }
        ],
        "primaryKey": {
          "columnNames": [
            "id"
          ],
          "autoGenerate": true
        },
        "indices": [],
        "foreignKeys": []
      }
    ],
    "setupQueries": [
      "CREATE TABLE IF NOT EXISTS room_master_table (id INTEGER PRIMARY KEY,identity_hash TEXT)",
      "INSERT OR REPLACE INTO room_master_table (id,identity_hash) VALUES(42, \"53db508c5248423325bd5393a1c88c03\")"
    ]
  }
}

If my understanding is correct, you will get such a file with every database version update, so that you can easily follow the history of your db.

You cannot style a variable such as $ip['countryName']

You can only style elements like p,div, etc, or classes and ids.

If you want to style $ip['countryName'] there are several ways.

You can echo it within an element:

echo '<p id="style">'.$ip['countryName'].'</p>';
echo '<span id="style">'.$ip['countryName'].'</span>';
echo '<div id="style">'.$ip['countryName'].'</div>';

If you want to style both the variables the same style, then set a class like:

echo '<p class="style">'.$ip['cityName'].'</p>';
echo '<p class="style">'.$ip['countryName'].'</p>';

You could also embed the variables within your actual html rather than echoing them out within the code.

$city = $ip['cityName'];  
$country = $ip['countryName'];
?>
<div class="style"><?php echo $city ?></div>
<div class="style"><?php echo $country?></div>

Ctrl+C sends a SIGINT signal.

kill -INT <pid> sends a SIGINT signal too:

# Terminates the program (like Ctrl+C)
kill -INT 888
# Force kill
kill -9 888

Assuming 888 is your process ID.

Note that kill 888 sends a SIGTERM signal, which is slightly different, but will also ask for the program to stop. So if you know what you are doing (no handler bound to SIGINT in the program), a simple kill is enough.

To get the PID of the last command launched in your script, use $! :

# Launch script in background
./my_script.sh &
# Get its PID
PID=$!
# Wait for 2 seconds
sleep 2
# Kill it
kill $PID

This worked for me. If field with name fieldA is clicked or any key entered it updates field with id fieldB.

jQuery("input[name='fieldA']").on("input", function() {
    jQuery('#fieldB').val(jQuery(this).val());
});

Something you can try is using the bind method, I think this achieves what you were asking for. If nothing else, it's still very useful.

function doClick(elem, func) {
  var diffElem = document.getElementById('some_element'); //could be the same or different element than the element in the doClick argument
  diffElem.addEventListener('click', func.bind(diffElem, elem))
}

function clickEvent(elem, evt) {
  console.log(this);
  console.log(elem); 
  // 'this' and elem can be the same thing if the first parameter 
  // of the bind method is the element the event is being attached to from the argument passed to doClick
  console.log(evt);
}

var elem = document.getElementById('elem_to_do_stuff_with');
doClick(elem, clickEvent);

Here is my solution for that:

EDIT - changed code a little bit

public static <E> Iterable<E> concat(final Iterable<? extends E> list1, Iterable<? extends E> list2)
{
    return new Iterable<E>()
    {
        public Iterator<E> iterator()
        {
            return new Iterator<E>()
            {
                protected Iterator<? extends E> listIterator = list1.iterator();
                protected Boolean checkedHasNext;

                }

                public boolean hasNext()
                {
                    if (checkedHasNext == null)
                        theNext();
                    return checkedHasNext;
                }

                public E next()
                {
                    if (!hasNext())
                        throw new NoSuchElementException();
                    checkedHasNext = null;
                    return nextValue;

                }

                public void remove()
                {
                    listIterator.remove();
                }
            };
        }
    };
}

In Bootstrap version 4. There some inbuilt classes to position text.

For centering table header and data text:

 <table>
    <tr>
      <th class="text-center">Text align center.</th>
    </tr>
    <tr>
      <td class="text-center">Text align center.</td>
    </tr>
  </table>

You can also use this classes to position any text.

<p class="text-left">Left aligned text on all viewport sizes.</p>
<p class="text-center">Center aligned text on all viewport sizes.</p>
<p class="text-right">Right aligned text on all viewport sizes.</p>

<p class="text-sm-left">Left aligned text on viewports sized SM (small) or wider.</p>
<p class="text-md-left">Left aligned text on viewports sized MD (medium) or wider.</p>
<p class="text-lg-left">Left aligned text on viewports sized LG (large) or wider.</p>
<p class="text-xl-left">Left aligned text on viewports sized XL (extra-large) or wider</p>

For more details

Hope it's help you.

JavaScript validation is not secure as anybody can change what your script does in the browser. Using it for enhancing the visual experience is ok though.

var textBox = document.getElementById("myTextBox");
var textLength = textBox.value.length;
if(textLength > 5)
{
    //red
    textBox.style.backgroundColor = "#FF0000";
}
else
{
    //green
    textBox.style.backgroundColor = "#00FF00";
}

If you want to change Status Bar Style from the launch screen, You should take this way.

1. Go to Project -> Target,

2. Set Status Bar Style to Light

3. Set View controller-based status bar appearance to NO in Info.plist.

From matplotlib version 2.1 onwards, you may use a figure legend. Instead of ax.legend(), which produces a legend with the handles from the axes ax, one can create a figure legend

fig.legend(loc="upper right")

which will gather all handles from all subplots in the figure. Since it is a figure legend, it will be placed at the corner of the figure, and the loc argument is relative to the figure.

import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(0,10)
y = np.linspace(0,10)
z = np.sin(x/3)**2*98

fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(x,y, '-', label = 'Quantity 1')

ax2 = ax.twinx()
ax2.plot(x,z, '-r', label = 'Quantity 2')
fig.legend(loc="upper right")

ax.set_xlabel("x [units]")
ax.set_ylabel(r"Quantity 1")
ax2.set_ylabel(r"Quantity 2")

plt.show()

In order to place the legend back into the axes, one would supply a bbox_to_anchor and a bbox_transform. The latter would be the axes transform of the axes the legend should reside in. The former may be the coordinates of the edge defined by loc given in axes coordinates.

fig.legend(loc="upper right", bbox_to_anchor=(1,1), bbox_transform=ax.transAxes)

In swift 2.0

var stringMe="Something In this.World"
var needle="."
if let idx = stringMe.characters.indexOf(needle) {
    let pos=stringMe.substringFromIndex(idx)
    print("Found \(needle) at position \(pos)")
}
else {
    print("Not found")
}

Open the Android SDK Manager and Update with latest.

I agree with somebody's recently deleted post that the differences in performance are so small that, with very very few exceptions, (he got dinged for saying never) you should not make your design decision based upon that.

In your example, where the elements are Objects, the performance difference should be minimal.

If you are dealing with a large number of primitives, an array will offer significantly better performance, both in memory and time.

I had a similar problem and in my case, the issue was different (I am using Django templates).

The order of JS was incorrect (I know that's the first thing you check but I was almost sure that that was not the case, but it was). The js calling the dialog was called before jqueryUI library was called.

I am using Django, so was inheriting a template and using {{super.block}} to inherit code from the block as well to the template. I had to move {{super.block}} at the end of the block which solved the issue. The js calling the dialog was declared in the Media class in Django's admin.py. I spent more than an hour to figure it out. Hope this helps someone.

remounting /dev/pts works for me. you can do this remotely via ssh if you run ssh like this against the affected machine. ssh doesn't request a tty when running commands like this and therefore this will allow you to remount /dev/pts remotely

ssh user@host -- 'mount -o remount,rw /dev/pts'

Alternatively, you can use XPathNavigator:

XmlDocument doc = new XmlDocument();
doc.LoadXml(xml);
XPathNavigator navigator = doc.CreateNavigator();

string books = GetStringValues("Books: ", navigator, "//Book/Title");
string authors = GetStringValues("Authors: ", navigator, "//Book/Author");

..

/// <summary>
/// Gets the string values.
/// </summary>
/// <param name="description">The description.</param>
/// <param name="navigator">The navigator.</param>
/// <param name="xpath">The xpath.</param>
/// <returns></returns>
private static string GetStringValues(string description,
                                      XPathNavigator navigator, string xpath) {
    StringBuilder sb = new StringBuilder();
    sb.Append(description);
    XPathNodeIterator bookNodesIterator = navigator.Select(xpath);
    while (bookNodesIterator.MoveNext())
       sb.Append(string.Format("{0} ", bookNodesIterator.Current.Value));
    return sb.ToString();
}

import { Injectable,OpaqueToken } from '@angular/core'; export const localStorage = new OpaqueToken('localStorage');

Place these lines in the top of the file, it should resolve the issue.

In Package Manager Console:

Update-Database Your_Migration_You_Want_To_Revert_To

More options and explanation on how to revert migrations can be seen here

To do it exactly your way? You could use the for...else structure

for url in list_of_urls:
    for url_dict in urls:
        if url_dict['url'] == url:
            url_dict['nbr'] += 1
            break
    else:
        urls.append(dict(url=url, nbr=1))

But it is quite inelegant. Do you really have to store the visited urls as a LIST? If you sort it as a dict, indexed by url string, for example, it would be way cleaner:

urls = {'http://www.google.fr/': dict(url='http://www.google.fr/', nbr=1)}

for url in list_of_urls:
    if url in urls:
        urls[url]['nbr'] += 1
    else:
        urls[url] = dict(url=url, nbr=1)

A few things to note in that second example:

• see how using a dict for urls removes the need for going through the whole urls list when testing for one single url. This approach will be faster.
• Using dict( ) instead of braces makes your code shorter
• using list_of_urls, urls and url as variable names make the code quite hard to parse. It's better to find something clearer, such as urls_to_visit, urls_already_visited and current_url. I know, it's longer. But it's clearer.

And of course I'm assuming that dict(url='http://www.google.fr', nbr=1) is a simplification of your own data structure, because otherwise, urls could simply be:

urls = {'http://www.google.fr':1}

for url in list_of_urls:
    if url in urls:
        urls[url] += 1
    else:
        urls[url] = 1

Which can get very elegant with the defaultdict stance:

urls = collections.defaultdict(int)
for url in list_of_urls:
    urls[url] += 1

It seems that you are mixing different Pythons here (Python 2.x vs. Python 3.x)... This is basically correct:

nb = input('Choose a number: ')

The problem is that it is only supported in Python 3. As @sharpner answered, for older versions of Python (2.x), you have to use the function raw_input:

nb = raw_input('Choose a number: ')

If you want to convert that to a number, then you should try:

number = int(nb)

... though you need to take into account that this can raise an exception:

try:
    number = int(nb)
except ValueError:
    print("Invalid number")

And if you want to print the number using formatting, in Python 3 str.format() is recommended:

print("Number: {0}\n".format(number))

Instead of:

print('Number %s \n' % (nb))

But both options (str.format() and %) do work in both Python 2.7 and Python 3.

This is an improved version of Anne's answer -- if you use perl, you can do the edit on the file 'in-place' rather than generating a new file:

perl -pi -e 's/\r\n|\n|\r/\r\n/g' file-to-convert  # Convert to DOS
perl -pi -e 's/\r\n|\n|\r/\n/g'   file-to-convert  # Convert to UNIX

if you don't want to use float

<div style="text-align:right; margin:0px auto 0px auto;">
<p> Hello </p>
</div>
  <div style="">
<p> Hello </p>
</div>

This is quite simple: my_data is a before defined structure type. So you want to declare an my_data-array of some elements, as you would do with

char a[] = { 'a', 'b', 'c', 'd' };

So the array would have 4 elements and you initialise them as

a[0] = 'a', a[1] = 'b', a[1] = 'c', a[1] ='d';

This is called a designated initializer (as i remember right).

and it just indicates that data has to be of type my_dat and has to be an array that needs to store so many my_data structures that there is a structure with each type member name Peter, James, John and Mike.

This happened to me using the Eclipse plug-in and synchronizing. The file causing the issue had no local changes (and in fact no remote changes since my last update). I chose "revert" for the file, with no other modifications to the files, and things returned to normal.

for(int i = 0; i < 1000; i++) {
   for(int j = 0; j < 1000; i++) {
       if(condition) {
            goto end;
   }
} 

end:

Not all browsers have native JSON support so there will be times where you need to use eval() to the JSON string. Use JSON parser from http://json.org as that handles everything a lot easier for you.

Eval() is an evil but against some browsers its a necessary evil but where you can avoid it, do so!!!!!

EventArgs e is a parameter called e that contains the event data, see the EventArgs MSDN page for more information.

Object Sender is a parameter called Sender that contains a reference to the control/object that raised the event.

Event Arg Class: http://msdn.microsoft.com/en-us/library/system.eventargs.aspx

Example:

protected void btn_Click (object sender, EventArgs e){
   Button btn = sender as Button;
   btn.Text = "clicked!";
}

Edit: When Button is clicked, the btn_Click event handler will be fired. The "object sender" portion will be a reference to the button which was clicked

is there a better way?

Well, if you are really looking for a better way, you can probably add another layer of abstraction on top of Rate. Well here is something I just came up with using Nullable Design Pattern.

using System;
using System.Collections.Generic;

namespace NullObjectPatternTest
{
    public class Program
    {
        public static void Main(string[] args)
        {
            var items = new List
                            {
                                new Item(RateFactory.Create(20)),
                                new Item(RateFactory.Create(null))
                            };

            PrintPricesForItems(items);
        }

        private static void PrintPricesForItems(IEnumerable items)
        {
            foreach (var item in items)
                Console.WriteLine("Item Price: {0:C}", item.GetPrice());
        }
    }

    public abstract class ItemBase
    {
        public abstract Rate Rate { get; }
        public int GetPrice()
        {
            // There is NO need to check if Rate == 0 or Rate == null
            return 1 * Rate.Value;
        }
    }

    public class Item : ItemBase
    {
        private readonly Rate _Rate;
        public override Rate Rate { get { return _Rate; } }
        public Item(Rate rate) { _Rate = rate; }
    }

    public sealed class RateFactory
    {
        public static Rate Create(int? rateValue)
        {
            if (!rateValue || rateValue == 0) 
                return new NullRate();
            return new Rate(rateValue);
        }
    }

    public class Rate
    {
        public int Value { get; set; }
        public virtual bool HasValue { get { return (Value > 0); } }
        public Rate(int value) { Value = value; }
    }

    public class NullRate : Rate
    {
        public override bool HasValue { get { return false; } }
        public NullRate() : base(0) { }
    }
}

I used this...

All above answers are correct here is another way with screenshot too.

From Chrome :

1. Right click "inspect" on the item you are trying to find the xpath
2. Right click on the highlighted area on the console.
3. Go to Copy xpath

Note that React's create-react-app tool-chain supports the null-coalescing since version 3.3.0 (released 5.12.2019). From the release notes:

Optional Chaining and Nullish Coalescing Operators

We now support the optional chaining and nullish coalescing operators!

// Optional chaining
a?.(); // undefined if `a` is null/undefined
b?.c; // undefined if `b` is null/undefined

// Nullish coalescing
undefined ?? 'some other default'; // result: 'some other default'
null ?? 'some other default'; // result: 'some other default'
'' ?? 'some other default'; // result: ''
0 ?? 300; // result: 0
false ?? true; // result: false

This said, in case you use create-react-app 3.3.0+ you can start using the null-coalesce operator already today in your React apps.

I am also very much interested to have a one-liner for this conversion, as far such a list is the default initializer for hashed in Perl.

Exceptionally comprehensive answer is given in this thread -

• python convert list to dictionary

Mine one I am newbie in Python), using Python 2.7 Generator Expressions, would be:

dict((a[i], a[i + 1]) for i in range(0, len(a) - 1, 2))

If you want to test explicitly for valid JSON (as opposed to the absence of the returned value false), then you can use a parsing approach as described here.

I had the same issue on a Windows 10 PC. I copied the project from my old computer to the new one, both 64 bits, and I installed the Oracle Client 64 bit on the new machine. I got the same error message, but after trying many solutions to no effect, what actually worked for me was this: In your Visual Studio (mine is 2017) go to Tools > Options > Projects and Solutions > Web Projects

On that page, check the option that says: Use the 64 bit version of IIS Express for Websites and Projects

The typical pattern is to check out the root project folder (=the one containing a file called ".project") from SVN using eclipse's svn integration (SVN repository exploring perspective). The project is then recognized automatically.

I've found the answer (by further examining the Sublime 2 config files structure):

I was to open

~/.config/sublime-text-2/Packages/Scala/Scala.tmLanguage

And edit it to add sbt (the extension of files I want to be opened as Scala code files) to the array after the fileTypes key:

<dict>
  <key>bundleUUID</key>
  <string>452017E8-0065-49EF-AB9D-7849B27D9367</string>
  <key>fileTypes</key>
  <array>
    <string>scala</string>
    <string>sbt</string>
  <array>
  ...

PS: May there be a better way, something like a right place to put my customizations (insted of modifying packages themselves), I'd still like to know.

My problem was solved by creating a Windows user without an accent or special characters and reinstalling android studio on that user. Another change is to change the environment variables:

Left Click in My Computer > Advanced System Settings> Advanced > Environment Variables

ANDROID_HOME = c:\my_sdk_path

ANDROID_SDK_ROOT = c:\my_sdk_path

JAVA_HOME = c:\program files\Java\yourJavaPath

• the default path of SDK is c:\users\youruser\AppData\LocalAndroid\sdk

Add in Path Variable the values:

1. %ANDROID_HOME%\platform-tools

2. %ANDROID_HOME%\tools

After changes, restart windows and try again!

Just as an FYI, in Rails 2 you can do

ActiveRecord::Base.silence { <code you don't want to log goes here> }

Obviously the curly braces could be replaced with a do end block if you wanted.

Using SQL Server 2012 Express.

My error (from the SQL Manager - Restore Database Dialog):

No backupset selected to be restored

Further, there were no backupsets shown in the list to select.

The issue was that I had moved 1 of the 5 backup files to a folder where the SQL Server service logon user did not have permissions - I tried to add that user, but could not get the NT Service\MSSQL$SQLEXPRESS user into the security list.

I moved the file under the Documents folder for the service user, and that enabled it to read all the files I had selected - 4 at that point - and the error changed to "media set missing" - then I looked around for another backup file, and when I added that I was able to restore.

The answers in this question helped me look in the right places and work my way to a solution.

var result;_x000D_
result = "1,2,3".split(","); _x000D_
console.log(result);

In Swift 3 :

It will generate random number between 0 to limit

let limit : UInt32 = 6
print("Random Number : \(arc4random_uniform(limit))")

you could trigger a click event on the corresponding tab link:

$(document).ready(function(){

  if(window.location.hash != "") {
      $('a[href="' + window.location.hash + '"]').click()
  }

});

There are multiple ways how to present a timespan in the database.

time

This datatype is supported since SQL Server 2008 and is the prefered way to store a TimeSpan. There is no mapping needed. It also works well with SQL code.

public TimeSpan ValidityPeriod { get; set; }

However, as stated in the original question, this datatype is limited to 24 hours.

datetimeoffset

The datetimeoffset datatype maps directly to System.DateTimeOffset. It's used to express the offset between a datetime/datetime2 to UTC, but you can also use it for TimeSpan.

However, since the datatype suggests a very specific semantic, so you should also consider other options.

datetime / datetime2

One approach might be to use the datetime or datetime2 types. This is best in scenarios where you need to process the values in the database directly, ie. for views, stored procedures, or reports. The drawback is that you need to substract the value DateTime(1900,01,01,00,00,00) from the date to get back the timespan in your business logic.

public DateTime ValidityPeriod { get; set; }

[NotMapped]
public TimeSpan ValidityPeriodTimeSpan
{
    get { return ValidityPeriod - DateTime(1900,01,01,00,00,00); }
    set { ValidityPeriod = DateTime(1900,01,01,00,00,00) + value; }
}

bigint

Another approach might be to convert the TimeSpan into ticks and use the bigint datatype. However, this approach has the drawback that it's cumbersome to use in SQL queries.

public long ValidityPeriod { get; set; }

[NotMapped]
public TimeSpan ValidityPeriodTimeSpan
{
    get { return TimeSpan.FromTicks(ValidityPeriod); }
    set { ValidityPeriod = value.Ticks; }
}

varchar(N)

This is best for cases where the value should be readable by humans. You might also use this format in SQL queries by utilizing the CONVERT(datetime, ValidityPeriod) function. Dependent on the required precision, you will need between 8 and 25 characters.

public string ValidityPeriod { get; set; }

[NotMapped]
public TimeSpan ValidityPeriodTimeSpan
{
    get { return TimeSpan.Parse(ValidityPeriod); }
    set { ValidityPeriod = value.ToString("HH:mm:ss"); }
}

Bonus: Period and Duration

Using a string, you can also store NodaTime datatypes, especially Duration and Period. The first is basically the same as a TimeSpan, while the later respects that some days and months are longer or shorter than others (ie. January has 31 days and February has 28 or 29; some days are longer or shorter because of daylight saving time). In such cases, using a TimeSpan is the wrong choice.

You can use this code to convert Periods:

using NodaTime;
using NodaTime.Serialization.JsonNet;

internal static class PeriodExtensions
{
    public static Period ToPeriod(this string input)
    {
        var js = JsonSerializer.Create(new JsonSerializerSettings());
        js.ConfigureForNodaTime(DateTimeZoneProviders.Tzdb);
        var quoted = string.Concat(@"""", input, @"""");
        return js.Deserialize<Period>(new JsonTextReader(new StringReader(quoted)));
    }
}

And then use it like

public string ValidityPeriod { get; set; }

[NotMapped]
public Period ValidityPeriodPeriod
{
    get => ValidityPeriod.ToPeriod();
    set => ValidityPeriod = value.ToString();
}

I really like NodaTime and it often saves me from tricky bugs and lots of headache. The drawback here is that you really can't use it in SQL queries and need to do calculations in-memory.

CLR User-Defined Type

You also have the option to use a custom datatype and support a custom TimeSpan class directly. See CLR User-Defined Types for details.

The drawback here is that the datatype might not behave well with SQL Reports. Also, some versions of SQL Server (Azure, Linux, Data Warehouse) are not supported.

Value Conversions

Starting with EntityFramework Core 2.1, you have the option to use Value Conversions.

However, when using this, EF will not be able to convert many queries into SQL, causing queries to run in-memory; potentially transfering lots and lots of data to your application.

So at least for now, it might be better not to use it, and just map the query result with Automapper.

empty() used to work for this, but the behavior of empty() has changed several times. As always, the php docs are always the best source for exact behavior and the comments on those pages usually provide a good history of the changes over time. If you want to check for a lack of object properties, a very defensive method at the moment is:

if (is_object($theObject) && (count(get_object_vars($theObject)) > 0)) {

If you don't use a passphrase, then the private key is not encrypted with any symmetric cipher - it is output completely unprotected.

You can generate a keypair, supplying the password on the command-line using an invocation like (in this case, the password is foobar):

openssl genrsa -aes128 -passout pass:foobar 3072

However, note that this passphrase could be grabbed by any other process running on the machine at the time, since command-line arguments are generally visible to all processes.

A better alternative is to write the passphrase into a temporary file that is protected with file permissions, and specify that:

openssl genrsa -aes128 -passout file:passphrase.txt 3072

Or supply the passphrase on standard input:

openssl genrsa -aes128 -passout stdin 3072

You can also used a named pipe with the file: option, or a file descriptor.

To then obtain the matching public key, you need to use openssl rsa, supplying the same passphrase with the -passin parameter as was used to encrypt the private key:

openssl rsa -passin file:passphrase.txt -pubout

(This expects the encrypted private key on standard input - you can instead read it from a file using -in <file>).

Example of creating a 3072-bit private and public key pair in files, with the private key pair encrypted with password foobar:

openssl genrsa -aes128 -passout pass:foobar -out privkey.pem 3072
openssl rsa -in privkey.pem -passin pass:foobar -pubout -out privkey.pub

1) On branch Development, check git status using following command:

git status

There should be no uncommitted code. If it is, push your code on Development branch:

git add *

git commit -m "My initial commit message"

git push origin Development

2) On Development branch, run following two commands:

git branch -f master HEAD

git push -f origin master

It will push your Development branch code to master branch.

**multiple delete not working**

function delete_selection() 
{
        $id_array = array();
        $selection = $this->input->post("selection", TRUE);
        $id_array = explode("|", $selection);

        foreach ($id_array as $item):
            if ($item != ''):
                //DELETE ROW
                $this->db->where('entry_id', $item);
                $this->db->delete('helpline_entry');
            endif;
        endforeach;
    }

In order to search for a specific method in a whole module

for method in dir(module) :
  if "keyword_of_methode" in method :
   print(method, end="\n")

With Homebrew installed:

brew install watch

You can do that I believe. It needs root permission. If you want to know where your apk files are stored, open a emulator and then go to

DDMS>File Explorer-> you can see a directory by name "data" -> Click on it and you will see a "app" folder.

Your apks are stored there. In fact just copying a apk directly to the folder works for me with emulators.

for integer types

#include <string.h>    

int array1[10] = {0,1,2,3,4,5,6,7,8,9};
int array2[10];


memcpy(array2,array1,sizeof(array1)); // memcpy("destination","source","size")

You can also use:

sudo lsof -i -n -P | grep TCP

This works in Mavericks.

Using BalusC's suggestion of implementing Collection i can now hide my primefaces p:dataTable using not empty operator on my dataModel that extends javax.faces.model.ListDataModel

Code sample:

import java.io.Serializable;
import java.util.Collection;
import java.util.List;
import javax.faces.model.ListDataModel;
import org.primefaces.model.SelectableDataModel;

public class EntityDataModel extends ListDataModel<Entity> implements
        Collection<Entity>, SelectableDataModel<Entity>, Serializable {

    public EntityDataModel(List<Entity> data) { super(data); }

    @Override
    public Entity getRowData(String rowKey) {
        // In a real app, a more efficient way like a query by rowKey should be
        // implemented to deal with huge data
        List<Entity> entitys = (List<Entity>) getWrappedData();
        for (Entity entity : entitys) {
            if (Integer.toString(entity.getId()).equals(rowKey)) return entity;
        }
        return null;
    }

    @Override
    public Object getRowKey(Entity entity) {
        return entity.getId();
    }

    @Override
    public boolean isEmpty() {
        List<Entity> entity = (List<Entity>) getWrappedData();
        return (entity == null) || entity.isEmpty();
    }
    // ... other not implemented methods of Collection...
}

In case someone is looking for how to configure MongoDB with authentication using docker-compose, here is a sample configuration using environment variables:

version: "3.3"

services:

  db:
      image: mongo
      environment:
        - MONGO_INITDB_ROOT_USERNAME=admin
        - MONGO_INITDB_ROOT_PASSWORD=<YOUR_PASSWORD>
      ports:
        - "27017:27017"

When running docker-compose up your mongo instance is run automatically with auth enabled. You will have a admin database with the given password.

Sometimes, the same error occurs when you forget to include the corresponding header.

An addition to Christopher Bradford's answer to use the HTML escaping anywhere, since most people don't use CGI nowadays, you can also use Rack:

require 'rack/utils'
Rack::Utils.escape_html('Usage: foo "bar" <baz>')

For Python 2.x:

':'.join(x.encode('hex') for x in 'Hello World!')

The code above will not work with Python 3.x, for 3.x, the code below will work:

':'.join(hex(ord(x))[2:] for x in 'Hello World!')

my solution is to use a timeout. Seems to work ok

$('input[type=text]').focus(function() {
    var _this = this;
    setTimeout(function() {
        _this.select();
    }, 10);
});

This should do the trick

var start = $('#start_date').val();
var end = $('#end_date').val();

// end - start returns difference in milliseconds 
var diff = new Date(end - start);

// get days
var days = diff/1000/60/60/24;

Example

var start = new Date("2010-04-01"),
    end   = new Date(),
    diff  = new Date(end - start),
    days  = diff/1000/60/60/24;

days; //=> 8.525845775462964

In my case it was related to vs-code running on my Linux machine. I ignored a warning which popped up about file watcher bla bla. The solution is on the vs-code docs page for linux https://code.visualstudio.com/docs/setup/linux#_visual-studio-code-is-unable-to-watch-for-file-changes-in-this-large-workspace-error-enospc

The solution is almost same (if not same) as the accepted answers, just has more explanation for anyone who gets here after running into the issues from vs-code.

First of all, regular expressions should not have surrounding quotes, so '/\s/g' should be /\s/g

In order to replace all non-alphanumerical characters with dashes, this should work (using your example code):

$("#Restaurant_Name").keyup(function(){
        var Text = $(this).val();
        Text = Text.toLowerCase();
        Text = Text.replace(/[^a-zA-Z0-9]+/g,'-');
        $("#Restaurant_Slug").val(Text);        
});

That should do the trick...

The logical OR '||' automatically short circuits if it meets a true condition once.

false || false || true || false = true, stops at second condition.

On the other hand, the logical AND '&&' automatically short circuits if it meets a false condition once.

false && true && true && true = false, stops at first condition.

Use: Path.GetFileName Method

var onlyFileName = System.IO.Path.GetFileName(ofd.FileName);

It is too late but might be it can help anyone

1. Create unique name for every control
2. Validate by using fromname[uniquname].$error

Sample code:

     ng-show="formName['QTY' +$index].$dirty || formName.$submitted">
   <div ng-message="required" class='error'>Required</div>
   <div ng-message="pattern" class='error'>Invalid Pattern</div>

Another (async) approach, using Identity's UserManager and SigninManager to reflect the change in the Identity cookie (and to optionally remove claims from db table AspNetUserClaims):

// Get User and a claims-based identity
ApplicationUser user = await UserManager.FindByIdAsync(User.Identity.GetUserId());
var Identity = new ClaimsIdentity(User.Identity);

// Remove existing claim and replace with a new value
await UserManager.RemoveClaimAsync(user.Id, Identity.FindFirst("AccountNo"));
await UserManager.AddClaimAsync(user.Id, new Claim("AccountNo", value));

// Re-Signin User to reflect the change in the Identity cookie
await SignInManager.SignInAsync(user, isPersistent: false, rememberBrowser: false);

// [optional] remove claims from claims table dbo.AspNetUserClaims, if not needed
var userClaims = UserManager.GetClaims(user.Id);
if (userClaims.Any())
{
  foreach (var item in userClaims)
  {
    UserManager.RemoveClaim(user.Id, item);
  }
}

from https://docs.angularjs.org/api/ng/function/angular.element

angular.element

wraps a raw DOM element or HTML string as a jQuery element (If jQuery is not available, angular.element delegates to Angular's built-in subset of jQuery, called "jQuery lite" or "jqLite.")

So you simply could do:

angular.module('myApp.filters', []).
  filter('htmlToPlaintext', function() {
    return function(text) {
      return angular.element(text).text();
    }
  }
);

Usage:

<div>{{myText | htmlToPlaintext}}</div>

x = 9
y = 8

unary

++x
--x

Binary

z = x + y

Ternary

2>3 ? true : false;
2<3 ? true : false;
2<3 ? "2 is lesser than 3" : "2 is greater than 3";

Quick fix: Change how excel converts imported files. Go to 'File', then 'Options', then 'Advanced'. Scroll down and uncheck 'Use system seperators'. Also change 'Decimal separator' to '.' and 'Thousands separator' to ',' . Then simply 're-save' your file in the CSV (Comma delimited) format. The root cause is usually associated with how the csv file is created. Trust that helps. Point is, why use extra code if not necessary? Cross-platform understanding and integration is key in engineering/development.

If MySQL has ROW_NUMBER, then the MEDIAN is (be inspired by this SQL Server query):

WITH Numbered AS 
(
SELECT *, COUNT(*) OVER () AS Cnt,
    ROW_NUMBER() OVER (ORDER BY val) AS RowNum
FROM yourtable
)
SELECT id, val
FROM Numbered
WHERE RowNum IN ((Cnt+1)/2, (Cnt+2)/2)
;

The IN is used in case you have an even number of entries.

If you want to find the median per group, then just PARTITION BY group in your OVER clauses.

you can use key function of php to get the key name:

<?php
    $array = array(
    'fruit1' => 'apple',
    'fruit2' => 'orange',
    'fruit3' => 'grape',
    'fruit4' => 'apple',
    'fruit5' => 'apple');

    // this cycle echoes all associative array
    // key where value equals "apple"
    while ($fruit_name = current($array)) {
      if ($fruit_name == 'apple') {
        echo key($array).'<br />';
      }
    next($array);
     }
?>

like here : PHP:key - Manual

You need to store the psftp script (lines from open to bye) into a separate file and pass that to psftp using -b switch:

cd "C:\Program Files (x86)\PuTTY"
psftp -b "C:\path\to\script\script.txt"

Reference:
https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter6.html#psftp-option-b

EDIT: For username+password: As you cannot use psftp commands in a batch file, for the same reason, you cannot specify the username and the password as psftp commands. These are inputs to the open command. While you can specify the username with the open command (open <user>@<IP>), you cannot specify the password this way. This can be done on a psftp command line only. Then it's probably cleaner to do all on the command-line:

cd "C:\Program Files (x86)\PuTTY"
psftp -b script.txt <user>@<IP> -pw <PW>

And remove the open, <user> and <PW> lines from your script.txt.

What you are doing atm is that you run psftp without any parameter or commands. Once you exit it (like by typing bye), your batch file continues trying to run open command (and others), what Windows shell obviously does not understand.

If you really want to keep everything in one file (the batch file), you can write commands to psftp standard input, like:

(
    echo cd ...
    echo lcd ...
    echo put log.sh
) | psftp -b script.txt <user>@<IP> -pw <PW>

Here is the example works fine in oracle

select to_char(columnname, 'DD/MON/yyyy'), count(*) from table_name group by to_char(createddate, 'DD/MON/yyyy');

Just store a regular datetime and ignore everything else. Why spend extra time writing code that loads an int, manipulates it, and converts it into a datetime, when you could just load a datetime?
