HFOE put a good link as the first comment on this thread. Camickr also has a description of active painting vs. drawing to a BufferedImage in the Custom Painting Approaches article.

See also this approach using painting in a BufferedImage.

The fillOval fits an oval inside a rectangle, with width=r, height = r you get a circle. If you want fillOval(x,y,r,r) to draw a circle with the center at (x,y) you will have to displace the rectangle by half its width and half its height.

public void drawCenteredCircle(Graphics2D g, int x, int y, int r) {
  x = x-(r/2);
  y = y-(r/2);
  g.fillOval(x,y,r,r);
}

This will draw a circle with center at x,y

Two things you can do here:

1. Read Painting in AWT and Swing
2. Use a debugger and put a breakpoint in the paintComponent method. Then travel up the stacktrace and see how provides the Graphics parameter.

Just for info, here is the stacktrace that I got from the example of code I posted at the end:

The Graphics parameter comes from here:

RepaintManager.paintDirtyRegions(Map) line: 781 

The snippet involved is the following:

Graphics g = JComponent.safelyGetGraphics(
                        dirtyComponent, dirtyComponent);
                // If the Graphics goes away, it means someone disposed of
                // the window, don't do anything.
                if (g != null) {
                    g.setClip(rect.x, rect.y, rect.width, rect.height);
                    try {
                        dirtyComponent.paint(g); // This will eventually call paintComponent()
                    } finally {
                        g.dispose();
                    }
                }

If you take a look at it, you will see that it retrieve the graphics from the JComponent itself (indirectly with javax.swing.JComponent.safelyGetGraphics(Component, Component)) which itself takes it eventually from its first "Heavyweight parent" (clipped to the component bounds) which it self takes it from its corresponding native resource.

Regarding the fact that you have to cast the Graphics to a Graphics2D, it just happens that when working with the Window Toolkit, the Graphics actually extends Graphics2D, yet you could use other Graphics which do "not have to" extends Graphics2D (it does not happen very often but AWT/Swing allows you to do that).

import java.awt.Color;
import java.awt.Graphics;

import javax.swing.JFrame;
import javax.swing.JPanel;

class TestPaint extends JPanel {

    public TestPaint() {
        setBackground(Color.WHITE);
    }

    @Override
    public void paintComponent(Graphics g) {
        super.paintComponent(g);
        g.drawOval(0, 0, getWidth(), getHeight());
    }

    public static void main(String[] args) {
        JFrame jFrame = new JFrame();
        jFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        jFrame.setSize(300, 300);
        jFrame.add(new TestPaint());
        jFrame.setVisible(true);
    }
}

Module named importlib allow to access to import internals. Especially, it provide function importlib.reload():

import importlib
importlib.reload(my_module)

In contrary of %autoreload, importlib.reload() also reset global variables set in module. In most cases, it is what you want.

importlib is only available since Python 3.1. For older version, you have to use module imp.

No, there isn't such constant.

If you removed the make all line from your "fresh" target:

fresh :
    rm -f *.o $(EXEC)
    clear

You could simply run the command make fresh all, which will execute as make fresh; make all.

Some might consider this as a second instance of make, but it's certainly not a sub-instance of make (a make inside of a make), which is what your attempt seemed to result in.

In windows just open the explorer navigate to your SLN folder click into search field and type kind:=folder;obj --> for obj folders use CTRL+A and delete 'em - same for bin Done

No need for any tool or extra software ;)

You can change your secret special value to 0, and exploit C's default structure-member semantics

struct foo bar = { .id = 42, .current_route = new_route };
update(&bar);

will then pass 0 as members of bar unspecified in the initializer.

Or you can create a macro that will do the default initialization for you:

#define FOO_INIT(...) { .id = -1, .current_route = -1, .quux = -1, ## __VA_ARGS__ }

struct foo bar = FOO_INIT( .id = 42, .current_route = new_route );
update(&bar);

It's been a while since this question was asked, hope can help. Because you can not change or alter the db structure, you can do this. according the postgresql docs.

TRUNCATE -- empty a table or set of tables.

TRUNCATE [ TABLE ] [ ONLY ] name [ * ] [, ... ]
    [ RESTART IDENTITY | CONTINUE IDENTITY ] [ CASCADE | RESTRICT ]

Description

TRUNCATE quickly removes all rows from a set of tables. It has the same effect as an unqualified DELETE on each table, but since it does not actually scan the tables it is faster. Furthermore, it reclaims disk space immediately, rather than requiring a subsequent VACUUM operation. This is most useful on large tables.

Truncate the table othertable, and cascade to any tables that reference othertable via foreign-key constraints:

TRUNCATE othertable CASCADE;

The same, and also reset any associated sequence generators:

TRUNCATE bigtable, fattable RESTART IDENTITY;

Truncate and reset any associated sequence generators:

TRUNCATE revinfo RESTART IDENTITY CASCADE ;

objdump -T *.so may also do the job

If you already have the full local copy, you can remove unwanted sub folders by using --set-depth command.

svn update --set-depth=exclude www

See: http://blogs.collab.net/subversion/sparse-directories-now-with-exclusion

The set-depth command support multipile paths.

Updating the root local copy will not change the depth of the modified folder.

To restore the folder to being recusively checkingout, you could use --set-depth again with infinity param.

svn update --set-depth=infinity www

The .selectedIndex of the select object has an index; you can use that to index into the .options array.

SELECT is_read_committed_snapshot_on FROM sys.databases 
WHERE name= 'YourDatabase'

Return value:

• 1: READ_COMMITTED_SNAPSHOT option is ON. Read operations under the READ COMMITTED isolation level are based on snapshot scans and do not acquire locks.
• 0 (default): READ_COMMITTED_SNAPSHOT option is OFF. Read operations under the READ COMMITTED isolation level use Shared (S) locks.

This one worked for me:

def list = [1,2,3,4]
for(item in list){
    println item
}

Source: Wikia.

you can use this method just pass your date to it

-(NSString *)getDateFromString:(NSString *)string
{

    NSString * dateString = [NSString stringWithFormat: @"%@",string];

    NSDateFormatter* dateFormatter = [[NSDateFormatter alloc] init];
    [dateFormatter setDateFormat:@"your current date format"];
    NSDate* myDate = [dateFormatter dateFromString:dateString];

    NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
    [formatter setDateFormat:@"your desired format"];
    NSString *stringFromDate = [formatter stringFromDate:myDate];

    NSLog(@"%@", stringFromDate);
    return stringFromDate;
}

Yes.

The new socket option allows multiple sockets on the same host to bind to the same port

You probably had a typo when you first ran it.

evaluating 0.5 % 0.3 returns '0.2' (A double) as expected.

Mindprod has a good overview of how modulus works in Java.

Laravel >= 5.3 method lists() is deprecated use pluck()

$items = Items::pluck('name', 'id');

{!! Form::select('items', $items, null, ['class' => 'some_css_class']) !!}

This will give you a select box with same select options as id numbers in DB

for example if you have this in your DB table:

id name
1  item1
2  item2
3  item3
4  item4

in select box it will be like this

<select>
<option value="1">item1</option>
<option value="2">item2</option>
<option value="3">item3</option>
<option value="4">item4</option>
</select>

I found out that pluck now returns a collection, and you need to add ->toArray() at the end of pluck...so like this: pluck('name', 'id')->toArray();

With the EncodingHelper plugin you can view the encoding of the file on the status bar. Also you can convert the encoding of the file and extended another functionalities.

char ch;
FILE *f = fopen("file.txt", "r");

if(fscanf(f,"%c",&ch)==EOF)
{
    printf("File is Empty");
}
fclose(f);

You could do something like this:

HTML

<div class="element">
   <span>Hi, I am Murtaza</span>
</div>

jQuery

$(".element span").text(function(index, text) { 
    return text.replace('am', 'am not'); 
});

Since you are using C++11, lambda-expression is a nice&clean solution.

class blub {
    void test() {}
  public:
    std::thread spawn() {
      return std::thread( [this] { this->test(); } );
    }
};

since this-> can be omitted, it could be shorten to:

std::thread( [this] { test(); } )

or just (deprecated)

std::thread( [=] { test(); } )

Here is an example that sorts by the header. This table is dynamic and changes with the JSON size.

I was able to build a dynamic table off of some other people's examples and documentation. http://jsfiddle.net/lastlink/v7pszemn/1/

<tr>
    <th class="{{header}}" ng-repeat="(header, value) in items[0]" ng-click="changeSorting(header)">
    {{header}}
  <i ng-class="selectedCls2(header)"></i>
</tr>

<tbody>
    <tr ng-repeat="row in pagedItems[currentPage] | orderBy:sort.sortingOrder:sort.reverse">
        <td ng-repeat="cell in row">
              {{cell}}
       </td>
    </tr>

Although the columns are out of order, on my .NET project they are in order.

Yes, there's in fact many reasons why you can access AWS Lambda like and HTTP Endpoint.

The architecture of AWS Lambda

It's a microservice. Running inside EC2 with Amazon Linux AMI (Version 3.14.26–24.46.amzn1.x86_64) and runs with Node.js. The memory can be beetwen 128mb and 1gb. When the data source triggers the event, the details are passed to a Lambda function as parameter's.

What happen?

AWS Lambda run's inside a container, and the code is directly uploaded to this container with packages or modules. For example, we NEVER can do SSH for the linux machine running your lambda function. The only things that we can monitor are the logs, with CloudWatchLogs and the exception that came from the runtime.

AWS take care of launch and terminate the containers for us, and just run the code. So, even that you use require('http'), it's not going to work, because the place where this code runs, wasn't made for this.

All solution that call length from array, add your code redundant null checkersconsider example:

int[] a = {1,2,3,4,5};
int[] b = Arrays.copyOf(a, a.length);
int[] c = a.clone();

//What if array a comes as local parameter? You need to use null check:

public void someMethod(int[] a) {
    if (a!=null) {
        int[] b = Arrays.copyOf(a, a.length);
        int[] c = a.clone();
    }
}

I recommend you not inventing the wheel and use utility class where all necessary checks have already performed. Consider ArrayUtils from apache commons. You code become shorter:

public void someMethod(int[] a) {
    int[] b = ArrayUtils.clone(a);
}

Apache commons you can find there

Instead of using pull-right class, it is better to use text-right class in the column, because pull-right creates problems sometimes while resizing the page.

npm start runs a script that the app maker built for easy starting of the app npm install installs all the packages in package.json

run npm install first

then run npm start

It's easier for me to think in these terms, but borrowing from other answers. The value you want is located in the series:

df[*column*][*row*]

where column and row point to the value you want returned. For your example, column is 'A' and for row you use a mask:

df['B'] == 3

To get the value from the series there are several options:

df['A'][df['B'] == 3].values[0]
df['A'][df['B'] == 3].iloc[0]
df['A'][df['B'] == 3].to_numpy()[0]

Figuring out package dependencies is really not that hard. You rarely do it anyway. Probably once during project setup and few more during upgrades. With maven you'll end up fixing mismatched dependencies, badly written poms, and doing package exclusions anyway.

Not that hard... for toy projects. But the projects I work on have many, really many, of them, and I'm very glad to get them transitively, to have a standardized naming scheme for them. Managing all this manually by hand would be a nightmare.

And yes, sometimes you have to work on the convergence of dependencies. But think about it twice, this is not inherent to Maven, this is inherent to any system using dependencies (and I am talking about Java dependencies in general here).

So with Ant, you have to do the same work except that you have to do everything manually: grabbing some version of project A and its dependencies, grabbing some version of project B and its dependencies, figuring out yourself what exact versions they use, checking that they don't overlap, checking that they are not incompatible, etc. Welcome to hell.

On the other hand, Maven supports dependency management and will retrieve them transitively for me and gives me the tooling I need to manage the complexity inherent to dependency management: I can analyze a dependency tree, control the versions used in transitive dependencies, exclude some of them if required, control the converge across modules, etc. There is no magic. But at least you have support.

And don't forget that dependency management is only a small part of what Maven offers, there is much more (not even mentioning the other tools that integrates nicely with Maven, e.g. Sonar).

Slow FIX-COMPILE-DEPLOY-DEBUG cycle, which kills productivity. This is my main gripe. You make a change, the you have to wait for maven build to kick in and wait for it to deploy. No hot deployment whatsoever.

First, why do you use Maven like this? I don't. I use my IDE to write tests, code until they pass, refactor, deploy, hot deploy and run a local Maven build when I'm done, before to commit, to make sure I will not break the continuous build.

Second, I'm not sure using Ant would make things much better. And to my experience, modular Maven builds using binary dependencies gives me faster build time than typical monolithic Ant builds. Anyway, have a look at Maven Shell for a ready to (re)use Maven environment (which is awesome by the way).

So at end, and I'm sorry to say so, it's not really Maven that is killing your productivity, it's you misusing your tools. And if you're not happy with it, well, what can I say, don't use it. Personally, I'm using Maven since 2003 and I never looked back.

Binding="{Binding YourColumn ,StringFormat='yyyy-MM-dd'}"

Just strengthening Jim's answer

Using presence one can do

class Task < ActiveRecord::Base
  before_save :default_values
  def default_values
    self.status = status.presence || 'P'
  end
end

If you use a stringbuilder, it would be efficient to initalize the length when you create the object. Length is going to be 2*lengthofString-1.

Or creating a char array and converting it back to the string would yield the same result.

Aand when you write some code please be sure that you write a few test cases as well, it will make your solution complete.

There are a couple of differences between the & and && operators. The same differences apply to | and ||. The most important thing to keep in mind is that && is a logical operator that only applies to boolean operands, while & is a bitwise operator that applies to integer types as well as booleans.

With a logical operation, you can do short circuiting because in certain cases (like the first operand of && being false, or the first operand of || being true), you do not need to evaluate the rest of the expression. This is very useful for doing things like checking for null before accessing a filed or method, and checking for potential zeros before dividing by them. For a complex expression, each part of the expression is evaluated recursively in the same manner. For example, in the following case:

(7 == 8) || ((1 == 3) && (4 == 4))

Only the emphasized portions will evaluated. To compute the ||, first check if 7 == 8 is true. If it were, the right hand side would be skipped entirely. The right hand side only checks if 1 == 3 is false. Since it is, 4 == 4 does not need to be checked, and the whole expression evaluates to false. If the left hand side were true, e.g. 7 == 7 instead of 7 == 8, the entire right hand side would be skipped because the whole || expression would be true regardless.

With a bitwise operation, you need to evaluate all the operands because you are really just combining the bits. Booleans are effectively a one-bit integer in Java (regardless of how the internals work out), and it is just a coincidence that you can do short circuiting for bitwise operators in that one special case. The reason that you can not short-circuit a general integer & or | operation is that some bits may be on and some may be off in either operand. Something like 1 & 2 yields zero, but you have no way of knowing that without evaluating both operands.

Why make it difficult and hassle with locks? Use Dispatch Barriers.

A dispatch barrier creates a synchronization point within a concurrent queue.

While it’s running, no other block on the queue is allowed to run, even if it’s concurrent and other cores are available.

If that sounds like an exclusive (write) lock, it is. Non-barrier blocks can be thought of as shared (read) locks.

As long as all access to the resource is performed through the queue, barriers provide very cheap synchronization.

You cannot check window.history.length as it contains the amount of pages in you visited in total in a given session:

window.history.length (Integer)

Read-only. Returns the number of elements in the session history, including the currently loaded page. For example, for a page loaded in a new tab this property returns 1. ^{Cite 1}

Lets say a user visits your page, clicks on some links and goes back:

www.mysite.com/index.html <-- first page and now current page                  <----+
www.mysite.com/about.html                                                           |
www.mysite.com/about.html#privacy                                                   | 
www.mysite.com/terms.html <-- user uses backbutton or your provided solution to go back

Now window.history.length is 4. You cannot traverse through the history items due to security reasons. Otherwise on could could read the user's history and get his online banking session id or other sensitive information.

You can set a timeout, that will enable you to act if the previous page isn't loaded in a given time. However, if the user has a slow Internet connection and the timeout is to short, this method will redirect him to your default location all the time:

window.goBack = function (e){
    var defaultLocation = "http://www.mysite.com";
    var oldHash = window.location.hash;

    history.back(); // Try to go back

    var newHash = window.location.hash;

    /* If the previous page hasn't been loaded in a given time (in this case
    * 1000ms) the user is redirected to the default location given above.
    * This enables you to redirect the user to another page.
    *
    * However, you should check whether there was a referrer to the current
    * site. This is a good indicator for a previous entry in the history
    * session.
    *
    * Also you should check whether the old location differs only in the hash,
    * e.g. /index.html#top --> /index.html# shouldn't redirect to the default
    * location.
    */

    if(
        newHash === oldHash &&
        (typeof(document.referrer) !== "string" || document.referrer  === "")
    ){
        window.setTimeout(function(){
            // redirect to default location
            window.location.href = defaultLocation;
        },1000); // set timeout in ms
    }
    if(e){
        if(e.preventDefault)
            e.preventDefault();
        if(e.preventPropagation)
            e.preventPropagation();
    }
    return false; // stop event propagation and browser default event
}

<span class="goback" onclick="goBack();">Go back!</span>

Note that typeof(document.referrer) !== "string" is important, as browser vendors can disable the referrer due to security reasons (session hashes, custom GET URLs). But if we detect a referrer and it's empty, it's probaly save to say that there's no previous page (see note below). Still there could be some strange browser quirk going on, so it's safer to use the timeout than to use a simple redirection.

EDIT: Don't use <a href='#'>...</a>, as this will add another entry to the session history. It's better to use a <span> or some other element. Note that typeof document.referrer is always "string" and not empty if your page is inside of a (i)frame.

I prefer outputting my data into XML (using Castor, XStream or JAXB), then transforming it using a XSLT stylesheet into XSL-FO and render that with Apache FOP into PDF. Worked so far for 10-page reports and 400-page manuals. I found this more flexible and stylable than generating PDFs in code using iText.

I tried several answers here, and none of them worked. Ironically, what did work was about the simplest alternative to a <br/> one could attempt:

<div style="flex-basis: 100%;"></div>

or you could also do:

<div style="width: 100%;"></div>

Place that wherever you want a new line. It seems to work even with adjacent <span>'s, but I'm using it with adjacent <div>'s.

Example: ajshdjashdjashdlasdlhdlSTARTasdasdsdaasdENDaknsdklansdlknaldknaaklsdn

1) START\w*END return: STARTasdasdsdaasdEND - will give you words between START and END

2) START\d*END return: START12121212END - will give you numbers between START and END

3) START\d*_\d*END return: START1212_1212END - will give you numbers between START and END having _

You make the http request

HttpResponse response = httpclient.execute(httpget);           
HttpEntity entity = response.getEntity();

inputStream = entity.getContent();

BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"), 8);
            StringBuilder sb = new StringBuilder();

You read the Buffer

String line = null;
while ((line = reader.readLine()) != null)
{
sb.append(line + "\n");
}
Log.d("Result", sb.toString());
result = sb.toString();

Create a JSONObject and pass the result string to the constructor:

JSONObject json = new JSONObject(result);

Parse the json results to your desired variables:

String usuario= json.getString("usuario");
int idperon = json.getInt("idperson");
String nombre = json.getString("nombre");

Do not forget to import:

import org.json.JSONObject;

You can use Excel's Index function:

=INDEX(Age, 5)

Try MySQL Workbench. It packs in very nice data modeling tools. Check out their screenshots for EER diagrams (Enhanced Entity Relationships, which are a notch up ER diagrams).

This isn't CakePHP specific, but you can modify the options so that the foreign keys and join tables follow the conventions that CakePHP uses. This would simplify your data modeling process once you've put the rules in place.

Same things but a bit easier way will be How to refresh parent page from page within iframe. Just call the parent page's function to invoke javascript function to reload the page:

window.location.reload();

Or do this directly from the page in iframe:

window.parent.location.reload();

Both works.

I've been learning android for the last few months, so I'm far from an expert, but I've been really disappointed with the documentation on ANRs.

Most of the advice seems to be geared towards avoiding them or fixing them by blindly looking through your code, which is great, but I couldn't find anything on analyzing the trace.

There are three things you really need to look for with ANR logs.

1) Deadlocks: When a thread is in the WAIT state, you can look through the details to find who it's "heldby=". Most of the time, it'll be held by itself, but if it's held by another thread, that's likely to be a danger sign. Go look at that thread and see what it's held by. You might find a loop, which is a clear sign that something has gone wrong. This is pretty rare, but it's the first point because when it happens, it's a nightmare

2) Main thread Waiting: If your main thread is in the WAIT state, check if it's held by another thread. This shouldn't happen, because your UI thread shouldn't be held by a background thread.

Both of these scenarios, mean you need to rework your code significantly.

3) Heavy operations on the main thread: This is the most common cause of ANRs, but sometimes one of the harder to find and fix. Look at the main thread details. Scroll down the stack trace and until you see classes you recognize (from your app). Look at the methods in the trace and figure out if you're making network calls, db calls, etc. in these places.

Finally, and I apologize for shamelessly plugging my own code, you can use the python log analyzer I wrote at https://github.com/HarshEvilGeek/Android-Log-Analyzer This will go through your log files, open ANR files, find deadlocks, find waiting main threads, find uncaught exceptions in your agent logs and print it all out on the screen in a relatively easy to read manner. Read the ReadMe file (which I'm about to add) to learn how to use it. It's helped me a ton in the last week!

I was having a similar problem. I wanted the selected text to end up in a command, but not rely on pasting it in. Here's the command I was trying to write a mapping for:

:call VimuxRunCommand("python")

The docs for this plugin only show using string literals. The following will break if you try to select text that contains doublequotes:

vnoremap y:call VimuxRunCommand("<c-r>"")<cr>

To get around this, you just reference the contents of the macro using @ :

vnoremap y:call VimuxRunCommand(@")<cr>

Passes the contents of the unnamed register in and works with my double quote and multiline edgecases.

The fastest is datediff, e.g.

select dateadd(d, datediff(d,0, [datecolumn]), 0), other..
from tbl

But if you only need to use the value, then you can skip the dateadd, e.g.

select ...
WHERE somedate <= datediff(d, 0, getdate())

where the expression datediff(d, 0, getdate()) is sufficient to return today's date without time portion.

Use WinSCP for file transfer over SSH, putty is only for SSH commands.

In my case the problem was that the class was located in test package. Moving it to main package has solved the problem.

SELECT 
    * 
FROM 
    table 
WHERE 
    column < (SELECT max(columnq) FROM table) 
ORDER BY 
    column DESC LIMIT 1

I have had the same problem and thanks to the posts here I have solved it. I knew that I have around a hundred files and I needed to run it for *.js files only. find . -type f -name '*.js' -print0 | xargs -0 dos2unix

Thank you all for your help.

The divs are treated as inline-elements. Just as a space or line-break between two spans would create a gap, it does between inline-blocks. You could either give them a negative margin or set word-spacing: -1; on the surrounding container.

The unix setup should be like the following:

 0 */3 * * * sh cron/update_old_citations.sh

Yes, use the rendered attribute.

<h:form rendered="#{some boolean condition}">

You usually tie it to the model rather than letting the model grab the component and manipulate it.

E.g.

<h:form rendered="#{bean.booleanValue}" />
<h:form rendered="#{bean.intValue gt 10}" />
<h:form rendered="#{bean.objectValue eq null}" />
<h:form rendered="#{bean.stringValue ne 'someValue'}" />
<h:form rendered="#{not empty bean.collectionValue}" />
<h:form rendered="#{not bean.booleanValue and bean.intValue ne 0}" />
<h:form rendered="#{bean.enumValue eq 'ONE' or bean.enumValue eq 'TWO'}" />

Note the importance of keyword based EL operators such as gt, ge, le and lt instead of >, >=, <= and < as angle brackets < and > are reserved characters in XML. See also this related Q&A: Error parsing XHTML: The content of elements must consist of well-formed character data or markup.

As to your specific use case, let's assume that the link is passing a parameter like below:

<a href="page.xhtml?form=1">link</a>

You can then show the form as below:

<h:form rendered="#{param.form eq '1'}">

(the #{param} is an implicit EL object referring to a Map representing the request parameters)

I just had a same issue of none of my console message showing. It was simply because I was using the new Edge (Chromium based) browser on Windows 10. It does not show my console messages whereas Chrome does. I guessed it was an issue with Edge because I had another odd issue with Edge because it treated strings with single quotes and double quotes differently.

New versions of excel have made old answers obsolete. It took a long time to make this, but it does a pretty good job. Note that the maximum image size is limited and the aspect ratio is ever so slightly off, as I was not able to perfectly optimize the reshaping math.

I think this will do the trick:

@change="$emit(variable)"

I have incorporated this (with little to no modification) into a UWP DataBinding Converter for my project and thought it might also be useful to others.

The code is:

using System;
using System.Text;
using Windows.UI.Xaml.Data;

namespace MyApp.Converters
{
    public class ByteSizeConverter : IValueConverter
    {
        static readonly string[] sSizeSuffixes = { "bytes", "KB", "MB", "GB", "TB", "PB", "EB", "ZB", "YB" };

        // The number of decimal places the formatter should include in the scaled output - default 1dp
        public int DecimalPlaces { get; set; } = 1;

        public object Convert(object value, Type targetType, object parameter, string language)
        {
            Int64 intVal = System.Convert.ToInt64(value);

            return SizeSuffix(intVal);
        }

        public object ConvertBack(object value, Type targetType, object parameter, string language)
        {
            // TODO: Parse string into number and suffix
            //       Scale number by suffix multiplier to get bytes
            throw new NotImplementedException();
        }

        string SizeSuffix(Int64 value)
        {
            if (this.DecimalPlaces < 0) { throw new ArgumentOutOfRangeException(String.Format("DecimalPlaces = {0}", this.DecimalPlaces)); }
            if (value < 0) { return "-" + SizeSuffix(-value); }
            if (value == 0) { return string.Format("{0:n" + this.DecimalPlaces + "} bytes", 0); }

            // magnitude is 0 for bytes, 1 for KB, 2, for MB, etc.
            int magnitude = (int)Math.Log(value, 1024);
            // clip magnitude - only 8 values currently supported, this prevents out-of-bounds exception
            magnitude = Math.Min(magnitude, 8);

            // 1L << (magnitude * 10) == 2 ^ (10 * magnitude) [i.e. the number of bytes in the unit corresponding to magnitude]
            decimal adjustedSize = (decimal)value / (1L << (magnitude * 10));

            // make adjustment when the value is large enough that it would round up to 1000 or more
            if (Math.Round(adjustedSize, this.DecimalPlaces) >= 1000)
            {
                magnitude += 1;
                adjustedSize /= 1024;
            }

            return String.Format("{0:n" + this.DecimalPlaces + "} {1}", adjustedSize, sSizeSuffixes[magnitude]);
        }
    }
}

To use it, add a local resource to your UserControl or Page XAML:

<UserControl.Resources>
    <converters:ByteSizeConverter x:Key="ByteFormat" DecimalPlaces="3" />
</UserControl.Resources>

Reference it in a data binding template or data binding instance:

<TextBlock HorizontalAlignment="Left" VerticalAlignment="Center"
    Text="{x:Bind MyItem.FileSize_bytes, Mode=OneWay, Converter={StaticResource ByteFormat}}" />

And hey presto. The magic happens.

I wrote you 2 classes to show you how it's done; Main and Customer. If you run the Main class you see what's going on:

import java.util.*;

public class Customer {

    private String name;
    private String email;

    public Customer(String name, String email) {
        this.name = name;
        this.email = email;
    }

    public String getName() {
        return name;
    }

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

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    @Override
    public String toString() {
        return name + " | " + email;
    }

    public static String toString(Collection<Customer> customers) {
        String s = "";
        for(Customer customer : customers) {
            s += customer + "\n";
        }
        return s;
    }

}


import java.util.*;

public class Main {

    public static void main(String[] args) {
        List<Customer> customers = new ArrayList<>();
        customers.add(new Customer("Bert", "[email protected]"));
        customers.add(new Customer("Ernie", "[email protected]"));
        System.out.println("customers before email change - start");
        System.out.println(Customer.toString(customers));
        System.out.println("end");
        customers.get(1).setEmail("[email protected]");
        System.out.println("customers after email change - start");
        System.out.println(Customer.toString(customers));
        System.out.println("end");
    }

}

to get this running, make 2 classes, Main and Customer and copy paste the contents from both classes to the correct class; then run the Main class.

You could loop through the array, printing out each item, as you loop. For example:

String[] items = {"item 1", "item 2", "item 3"};

for(int i = 0; i < items.length; i++) {

    System.out.println(items[i]);

}

Output:

item 1
item 2
item 3

Use forward slashes to specify the UNC Path:

open('//HOST/share/path/to/file')

(if your Python client code is also running under Windows)

You can use:

var dictionary = myList.ToDictionary(x => x);

You can extract the different parts out quite neatly using a regex pattern:

In [11]: df.row.str.extract('(?P<fips>\d{5})((?P<state>[A-Z ]*$)|(?P<county>.*?), (?P<state_code>[A-Z]{2}$))')
Out[11]: 
    fips                    1           state           county state_code
0  00000        UNITED STATES   UNITED STATES              NaN        NaN
1  01000              ALABAMA         ALABAMA              NaN        NaN
2  01001   Autauga County, AL             NaN   Autauga County         AL
3  01003   Baldwin County, AL             NaN   Baldwin County         AL
4  01005   Barbour County, AL             NaN   Barbour County         AL

[5 rows x 5 columns]

To explain the somewhat long regex:

(?P<fips>\d{5})

• Matches the five digits (\d) and names them "fips".

The next part:

((?P<state>[A-Z ]*$)|(?P<county>.*?), (?P<state_code>[A-Z]{2}$))

Does either (|) one of two things:

(?P<state>[A-Z ]*$)

• Matches any number (*) of capital letters or spaces ([A-Z ]) and names this "state" before the end of the string ($),

or

(?P<county>.*?), (?P<state_code>[A-Z]{2}$))

• matches anything else (.*) then
• a comma and a space then
• matches the two digit state_code before the end of the string ($).

In the example:
Note that the first two rows hit the "state" (leaving NaN in the county and state_code columns), whilst the last three hit the county, state_code (leaving NaN in the state column).

If you have a specific integer timestamp to insert/update, you can use PHP date() function with your timestamp as second arg :

date("Y-m-d H:i:s", $myTimestamp)

Below added code is working for me if you are using pattern dd-MM-yyyy.

public boolean isValidDate(String date) {
        boolean check;
        String date1 = "^(0?[1-9]|[12][0-9]|3[01])-(0?[1-9]|1[012])-([12][0-9]{3})$";
        check = date.matches(date1);

        return check;
    }

One option that might work is using WindowsIdentity.Impersonate (and change the thread principal) to become the desired user, like so. Back to p/invoke, though, I'm afraid...

Another cheeky (and equally far from ideal) option might be to spawn a process to do the work... ProcessStartInfo accepts a .UserName, .Password and .Domain.

Finally - perhaps run the service in a dedicated account that has access? (removed as you have clarified that this isn't an option).

Microsoft do not support C99 and haven't announced any plans to. I believe they intend to track C++ standards but consider C as effectively obsolete except as a subset of C++.

New projects in Visual Studio 2003 and later have the "Compile as C++ Code (/TP)" option set by default, so any .c files will be compiled as C++.

Partial mocking using Mockito's spy method could be the solution to your problem, as already stated in the answers above. To some degree I agree that, for your concrete use case, it may be more appropriate to mock the DB lookup. From my experience this is not always possible - at least not without other workarounds - that I would consider as being very cumbersome or at least fragile. Note, that partial mocking does not work with ally versions of Mockito. You have use at least 1.8.0.

I would have just written a simple comment for the original question instead of posting this answer, but StackOverflow does not allow this.

Just one more thing: I really cannot understand that many times a question is being asked here gets comment with "Why you want to do this" without at least trying to understand the problem. Escpecially when it comes to then need for partial mocking there are really a lot of use cases that I could imagine where it would be useful. That's why the guys from Mockito provided that functionality. This feature should of course not be overused. But when we talk about test case setups that otherwise could not be established in a very complicated way, spying should be used.

@Trevino: your answer helped me solve my problem. However, for a beginner, trying to give a step by step approach.

1. Get your current installation of java via $ echo $JAVA_HOME
2. $ crontab -e
3. * * * * * echo $PATH - this lets you understand whats the PATH value being used by crontab at present. Run crontab and grab $PATH value used by crontab.
4. Now edit crontab again to set your desired java bin path: a) crontab -e; b) PATH=<value of $JAVA_HOME>/bin:/usr/bin:/bin (its a sample path); c) now your scheduled job/script like */10 * * * * sh runMyJob.sh &; d) remove echo $PATH from crontab as its not needed now.

The simplest vanilla JS snippet I came up with:

document.addEventListener('keydown', function (event) {
  if (event.keyCode === 13 && event.target.nodeName === 'INPUT') {
    var form = event.target.form;
    var index = Array.prototype.indexOf.call(form, event.target);
    form.elements[index + 1].focus();
    event.preventDefault();
  }
});

Works in IE 9+ and modern browsers.

You can try the following steps and code using qrtools:

• Create a qrcode file, if not already existing

  • I used pyqrcode for doing this, which can be installed using pip install pyqrcode

  • And then use the code:

    >>> import pyqrcode
    >>> qr = pyqrcode.create("HORN O.K. PLEASE.")
    >>> qr.png("horn.png", scale=6)
    

• Decode an existing qrcode file using qrtools

  • Install qrtools using sudo apt-get install python-qrtools

  • Now use the following code within your python prompt

    >>> import qrtools
    >>> qr = qrtools.QR()
    >>> qr.decode("horn.png")
    >>> print qr.data
    u'HORN O.K. PLEASE.'
    

Here is the complete code in a single run:

In [2]: import pyqrcode
In [3]: qr = pyqrcode.create("HORN O.K. PLEASE.")
In [4]: qr.png("horn.png", scale=6)
In [5]: import qrtools
In [6]: qr = qrtools.QR()
In [7]: qr.decode("horn.png")
Out[7]: True
In [8]: print qr.data
HORN O.K. PLEASE.

Caveats

• You might need to install PyPNG using pip install pypng for using pyqrcode

• In case you have PIL installed, you might get IOError: decoder zip not available. In that case, try uninstalling and reinstalling PIL using:

  pip uninstall PIL
  pip install PIL
  

• If that doesn't work, try using Pillow instead

  pip uninstall PIL
  pip install pillow
  

If you need run thread predioticly with different codes here is example:

    public ESLThread() {

        if(mListener != null){

            mListener.onBackground();
        }
    }

    @Override
    protected List doInBackground(Void... params) {

        if(mListener != null){

            List list = mListener.onBackground();

            return list;
        }

        return null;
    }

    @Override
    protected void onPostExecute(List t) {
        if(mListener != null){

            if ( t != null) {
                mListener.onPostExecute(t);
            }
        }

    }


    public void setListener(ESLThreadListener mListener){

        this.mListener = mListener;
    }
}

Run different codes:

  ESLThread thread = new ESLThread();
                        thread.setListener(new ESLThreadListener() {
                            @Override
                            public List onBackground() {
                                List<EntityShoppingListItems>  data = RoomDB.getDatabase(context).sliDAO().getSL(fId);

                                return data;

                            }

                            @Override
                            public void onPostExecute(List t) {

                                List<EntityShoppingListItems> data = (List<EntityShoppingListItems>)t;
                                adapter.setList(data);
                            }
                        });

                        thread.execute();

I found the solution:

function onClick(e) {alert(this.getLatLng());}

used the method getLatLng() of the marker

If you don't want to use the AWT Color.decode, then just copy the contents of the method:

int i = Integer.decode("#FFFFFF");
int[] rgb = new int[]{(i >> 16) & 0xFF, (i >> 8) & 0xFF, i & 0xFF};

Integer.decode handles the # or 0x, depending on how your string is formatted

Do this

...
var el = document.getElementById('targetFrame');

var frame_win = getIframeWindow(el);

console.log(frame_win);
...

getIframeWindow is defined here

function getIframeWindow(iframe_object) {
  var doc;

  if (iframe_object.contentWindow) {
    return iframe_object.contentWindow;
  }

  if (iframe_object.window) {
    return iframe_object.window;
  } 

  if (!doc && iframe_object.contentDocument) {
    doc = iframe_object.contentDocument;
  } 

  if (!doc && iframe_object.document) {
    doc = iframe_object.document;
  }

  if (doc && doc.defaultView) {
   return doc.defaultView;
  }

  if (doc && doc.parentWindow) {
    return doc.parentWindow;
  }

  return undefined;
}

You're looking for $anchorScroll().

Here's the (crappy) documentation.

And here's the source.

Basically you just inject it and call it in your controller, and it will scroll you to any element with the id found in $location.hash()

app.controller('TestCtrl', function($scope, $location, $anchorScroll) {
   $scope.scrollTo = function(id) {
      $location.hash(id);
      $anchorScroll();
   }
});

<a ng-click="scrollTo('foo')">Foo</a>

<div id="foo">Here you are</div>

Here is a plunker to demonstrate

EDIT: to use this with routing

Set up your angular routing as usual, then just add the following code.

app.run(function($rootScope, $location, $anchorScroll, $routeParams) {
  //when the route is changed scroll to the proper element.
  $rootScope.$on('$routeChangeSuccess', function(newRoute, oldRoute) {
    $location.hash($routeParams.scrollTo);
    $anchorScroll();  
  });
});

and your link would look like this:

<a href="#/test?scrollTo=foo">Test/Foo</a>

Here is a Plunker demonstrating scrolling with routing and $anchorScroll

And even simpler:

app.run(function($rootScope, $location, $anchorScroll) {
  //when the route is changed scroll to the proper element.
  $rootScope.$on('$routeChangeSuccess', function(newRoute, oldRoute) {
    if($location.hash()) $anchorScroll();  
  });
});

and your link would look like this:

<a href="#/test#foo">Test/Foo</a>

Use .blur().

The blur event is sent to an element when it loses focus. Originally, this event was only applicable to form elements, such as <input>. In recent browsers, the domain of the event has been extended to include all element types. An element can lose focus via keyboard commands, such as the Tab key, or by mouse clicks elsewhere on the page.

$("#myInputID").blur(); 

I found these instructions on a blog post that indicated this step, which worked for me (Windows 8, 64-bit):

Make sure that in windows features, you have both WCF options under .Net framework are ticked. So go to Control Panel –> Programs and Features –> Turn Windows Features ON/Off –> Features –> Add Features –> .NET Framework X.X Features. Make sure that .Net framework says it is installed, and make sure that the WCF Activation node underneath it is selected (checkbox ticked) and both options under WCF Activation are also checked.

These are:
* HTTP Activation
* Non-HTTP Activation
Both options need to be selected (checked box ticked).

1. Another alternative is to use Pycharm IDE. For each project, you can set the Project Interpreter in Settings.

2. For example, if anaconda is installed in /home/user/anaconda2/bin/python, you can select the Project Interpreter and set to this folder.

3. Since the whole project is set to Anaconda's path, you can import any module which is packaged within Anaconda.

dir(module) is the standard way when using a script or the standard interpreter, as mentioned in most answers.

However with an interactive python shell like IPython you can use tab-completion to get an overview of all objects defined in the module. This is much more convenient, than using a script and print to see what is defined in the module.

• module.<tab> will show you all objects defined in the module (functions, classes and so on)
• module.ClassX.<tab> will show you the methods and attributes of a class
• module.function_xy? or module.ClassX.method_xy? will show you the docstring of that function / method
• module.function_x?? or module.SomeClass.method_xy?? will show you the source code of the function / method.

I follow this version,

Swift 4:

import Foundation

class AELinkedClickableUILabel: UILabel {

    typealias YourCompletion = () -> Void

    var linkedRange: NSRange!
    var completion: YourCompletion?

    @objc func linkClicked(sender: UITapGestureRecognizer){

        if let completionBlock = completion {

            let textView = UITextView(frame: self.frame)
            textView.text = self.text
            textView.attributedText = self.attributedText
            let index = textView.layoutManager.characterIndex(for: sender.location(in: self),
                                                              in: textView.textContainer,
                                                              fractionOfDistanceBetweenInsertionPoints: nil)

            if linkedRange.lowerBound <= index && linkedRange.upperBound >= index {

                completionBlock()
            }
        }
    }

/**
 *  This method will be used to set an attributed text specifying the linked text with a
 *  handler when the link is clicked
 */
    public func setLinkedTextWithHandler(text:String, link: String, handler: @escaping ()->()) -> Bool {

        let attributextText = NSMutableAttributedString(string: text)
        let foundRange = attributextText.mutableString.range(of: link)

        if foundRange.location != NSNotFound {
            self.linkedRange = foundRange
            self.completion = handler
            attributextText.addAttribute(NSAttributedStringKey.link, value: text, range: foundRange)
            self.isUserInteractionEnabled = true
            self.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(linkClicked(sender:))))
            return true
        }
        return false
    }
}

Call Example:

button.setLinkedTextWithHandler(text: "This website (stackoverflow.com) is awesome", link: "stackoverflow.com") 
{
    // show popup or open to link
}

Remember that a multi-dimensional array is like a table. You don't have an x element and a y element for each entry; you have a string at (for instance) table[1,2].

So, each entry is still only one string (in your example), it's just an entry at a specific x/y value. So, to get both entries at table[1, x], you'd do a nested for loop. Something like the following (not tested, but should be close)

for (int x = 0; x < table.Length; x++)
{
    for (int y = 0; y < table.Length; y += 2)
    {
        Console.WriteLine("{0} {1}", table[x, y], table[x, y + 1]);
    }
}

This indicates the linux has delivered a SIGTERM to your process. This is usually at the request of some other process (via kill()) but could also be sent by your process to itself (using raise()). This signal requests an orderly shutdown of your process.

If you need a quick cheatsheet of signal numbers, open a bash shell and:

$ kill -l
 1) SIGHUP   2) SIGINT   3) SIGQUIT  4) SIGILL
 5) SIGTRAP  6) SIGABRT  7) SIGBUS   8) SIGFPE
 9) SIGKILL 10) SIGUSR1 11) SIGSEGV 12) SIGUSR2
13) SIGPIPE 14) SIGALRM 15) SIGTERM 16) SIGSTKFLT
17) SIGCHLD 18) SIGCONT 19) SIGSTOP 20) SIGTSTP
21) SIGTTIN 22) SIGTTOU 23) SIGURG  24) SIGXCPU
25) SIGXFSZ 26) SIGVTALRM   27) SIGPROF 28) SIGWINCH
29) SIGIO   30) SIGPWR  31) SIGSYS  34) SIGRTMIN
35) SIGRTMIN+1  36) SIGRTMIN+2  37) SIGRTMIN+3  38) SIGRTMIN+4
39) SIGRTMIN+5  40) SIGRTMIN+6  41) SIGRTMIN+7  42) SIGRTMIN+8
43) SIGRTMIN+9  44) SIGRTMIN+10 45) SIGRTMIN+11 46) SIGRTMIN+12
47) SIGRTMIN+13 48) SIGRTMIN+14 49) SIGRTMIN+15 50) SIGRTMAX-14
51) SIGRTMAX-13 52) SIGRTMAX-12 53) SIGRTMAX-11 54) SIGRTMAX-10
55) SIGRTMAX-9  56) SIGRTMAX-8  57) SIGRTMAX-7  58) SIGRTMAX-6
59) SIGRTMAX-5  60) SIGRTMAX-4  61) SIGRTMAX-3  62) SIGRTMAX-2
63) SIGRTMAX-1  64) SIGRTMAX    

You can determine the sender by using an appropriate signal handler like:

#include <signal.h>
#include <stdio.h>
#include <stdlib.h>

void sigterm_handler(int signal, siginfo_t *info, void *_unused)
{
  fprintf(stderr, "Received SIGTERM from process with pid = %u\n",
      info->si_pid);
  exit(0);
}

int main (void)
{
  struct sigaction action = {
    .sa_handler = NULL,
    .sa_sigaction = sigterm_handler,
    .sa_mask = 0,
    .sa_flags = SA_SIGINFO,
    .sa_restorer = NULL
  };

  sigaction(SIGTERM, &action, NULL);
  sleep(60);

  return 0;
}

Notice that the signal handler also includes a call to exit(). It's also possible for your program to continue to execute by ignoring the signal, but this isn't recommended in general (if it's a user doing it there's a good chance it will be followed by a SIGKILL if your process doesn't exit, and you lost your opportunity to do any cleanup then).

To specify a directory to search for (binary) libraries, you just use -L:

-L/data[...]/lib

To specify the actual library name, you use -l:

-lfoo  # (links libfoo.a or libfoo.so)

To specify a directory to search for include files (different from libraries!) you use -I:

-I/data[...]/lib

So I think what you want is something like

g++ -g -Wall -I/data[...]/lib testing.cpp fileparameters.cpp main.cpp -o test

These compiler flags (amongst others) can also be found at the GNU GCC Command Options manual:

• 3.16 Options for Directory Search

Run it under a different user name, using "runas" or by scheduling it under a different user in Windows Scheduled Tasks.

The spec can be read as "ISO-8859-1" or "undefined". Your choice. It's known that many servers use ISO-8859-1 (like it or not) and will fail when you send something else.

For more information and a proposal to fix the situation, see http://greenbytes.de/tech/webdav/draft-reschke-basicauth-enc-latest.html

You should \usepackage{longtable}.

• PDF Documentation of the package: ftp://ftp.tex.ac.uk/tex-archive/macros/latex/required/tools/longtable.pdf
• Tutorial with examples can be found here.

I used the property

display: table;

and

display: table-cell;

to achieve the same.Link to fiddle below shows 3 tables wrapped in divs and these divs are further wrapped in a parent div

<div id='content'>
   <div id='div-1'><!-- COntains table --></div>
   <div id='div-2'><!-- contains two more divs that require to be arranged one below other --></div>
</div>

Here is the jsfiddle: http://jsfiddle.net/vikikamath/QU6WP/1/ I thought this might be helpful to someone looking to set divs in same line without using display-inline

I know this is an older post, but I just got hit with a similar issue and was able to resolve it, so I thought I'd share.

(Update: As noted in the comments below, this answer was before the inclusion of the "git stash" feature to eGit.)

What I did was:

1. Copy out the local copy of the conflicting file that may or may not have any changes from the version on the upstream.
2. Within Eclipse, "Revert" the file to the version right before the conflict.
3. Run a "Pull" from the remote repository, allowing all changes to be synced to the local work directory. This should clear the updates coming down to your filesystem, leaving only what you have left to push.
4. Check the current version of the conflicting file in your work directory with the copy you copied out. If there are any differences, do a proper merge of the files and commit that version of the file in the work directory.
5. Now "Push" your changes up.

Hope that helps.

Get a count of only the directories in the current directory

echo */ | wc

you will get out put like 1 309 4594

2nd digit represents no. of directories.

or

tree -L 1 | tail -1

var newTH = document.createElement('th');
newTH.innerHTML = 'Hello, World!';
newTH.onclick = function () {
    this.parentElement.removeChild(this);
};

var table = document.getElementById('content');
table.appendChild(newTH);

Working example: http://jsfiddle.net/23tBM/

You can also just hide with this.style.display = 'none'.

For Microsoft, the answer is different. VS2013 is largely C99 compliant but "[t]he hh, j, z, and t length prefixes are not supported." For size_t "that is, unsigned __int32 on 32-bit platforms, unsigned __int64 on 64-bit platforms" use prefix I (capital eye) with type specifier o, u, x, or X. See VS2013 Size specification

As for off_t, it is defined as long in VC\include\sys\types.h.

Constraints are nothing but the rules on the data. What data is valid and what is invalid can be defined using constraints. So, that integrity of data can be maintained. Following are the widely used constraints:

1. Primary Key : which uniquely identifies the data . If this constraint has been specified for certain column then we can't enter duplicate data in that column
2. Check : Such as NOT NULL . Here we can specify what data we can enter for that particular column and what is not expected for that column.
3. Foreign key : Foreign key references to the row of other table. So that data referred in one table from another table is always available for the referencing table.

Use Awk.

awk '{ print length }' abc.txt

I copy-pasted the whole pdf in a text editor and got something like:

...
31 Netherlands (Kingdom of the)  
32 Belgium  
33 France  
34 Spain  
350 Gibraltar  
351 Portugal  
352 Luxembourg  
353 Ireland  
354 Iceland
...

You could easily parse this to create a xml :)

Append extra an [ and ] to the beginning and end of the string. This will make it an array. Then use eval() or some safe JSON serializer to serialize the string and make it a real JavaScript datatype.

You should use https://github.com/douglascrockford/JSON-js instead of eval(). eval is only if you're doing some quick debugging/testing.

The time complexity of ArrayList.clear() is O(n) and of removeAll is O(n^2).

So yes, ArrayList.clear is much faster.

I have Python 2 and Python 3 installed on my computer. For some strange reason I have in the sys.path of Python 3 also a path to the sitepackage library directory of Python2 when the re module is called. If I run Python 3 and import enum and print(enum.__file__) the system does not show this Python 2 path to site-packages. So a very rough and dirty hack is, to directly modify the module in which enum is imported (follow the traceback paths) and insert the following code just before importing enum:

import sys
for i, p in enumerate(sys.path):
    if "python27" in p.lower() or "python2.7" in p.lower(): sys.path.pop(i)
import enum

That solved my problem.

you can do it like this:

cell[B1]: 0:04:58.727

cell[B2]: =FIND(".";B1)

cell[B3]: =LEFT(B1;B2-7)

cell[B4]: =MID(B1;11-8;2)

cell[B5]: =RIGHT(B1;6)

cell[B6]: =B3*3600000+B4*60000+B5

maybe you have to multiply B5 also with 1000.

=FIND(".";B1) is only necessary because you might have inputs like '0:04:58.727' or '10:04:58.727' with different length.

To answer your question directly:

The single most important difference between the two is that you should start using JupyterLab straight away, and that you should not worry about Jupyter Notebook at all. Because:

JupyterLab will eventually replace the classic Jupyter Notebook. Throughout this transition, the same notebook document format will be supported by both the classic Notebook and JupyterLab

But you would also like to also know this:

Other posts have suggested that Jupyter Notebook (JN) could potentially be easier to use than JupyterLab (JL) for beginners. But I would have to disagree.

A great advantage with JL, and arguably one of the most important differences between JL and JN, is that you can more easily run a single line and even highlighted text. I prefer using a keyboard shortcut for this, and assigning shortcuts is pretty straight-forward.

And the fact that you can execute code in a Python console makes JL much more fun to work with. Other answers have already mentioned this, but JL can in some ways be considered a tool to run Notebooks and more. So the way I use JupyterLab is by having it set up with an .ipynb file, a file browser and a python console like this:

And now you have these tools at your disposal:

1. View Files, running kernels, Commands, Notebook Tools, Open Tabs or Extension manager
2. Run cells using, among other options, Ctrl+Enter
3. Run single expression, line or highlighted text using menu options or keyboard shortcuts
4. Run code directly in a console using Shift+Enter
5. Inspect variables, dataframes or plots quickly and easily in a console without cluttering your notebook output.

One interesting thing to point here; the usual way of using OR and AND too will work in this case, but with a small change. Instead of "and" and instead of "or", rather use Ampersand(&) and Pipe Operator(|) and it will work.

When we use 'and':

ar = np.array([3,4,5,14,2,4,3,7])
np.where((ar>3) and (ar<6), 'yo', ar)

Output:
ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()

When we use Ampersand(&):

ar = np.array([3,4,5,14,2,4,3,7])
np.where((ar>3) & (ar<6), 'yo', ar)

Output:
array(['3', 'yo', 'yo', '14', '2', 'yo', '3', '7'], dtype='<U11')

And this is same in the case when we are trying to apply multiple filters in case of pandas Dataframe. Now the reasoning behind this has to do something with Logical Operators and Bitwise Operators and for more understanding about same, I'd suggest to go through this answer or similar Q/A in stackoverflow.

UPDATE

A user asked, why is there a need for giving (ar>3) and (ar<6) inside the parenthesis. Well here's the thing. Before I start talking about what's happening here, one needs to know about Operator precedence in Python.

Similar to what BODMAS is about, python also gives precedence to what should be performed first. Items inside the parenthesis are performed first and then the bitwise operator comes to work. I'll show below what happens in both the cases when you do use and not use "(", ")".

Case1:

np.where( ar>3 & ar<6, 'yo', ar)
np.where( np.array([3,4,5,14,2,4,3,7])>3 & np.array([3,4,5,14,2,4,3,7])<6, 'yo', ar)

Since there are no brackets here, the bitwise operator(&) is getting confused here that what are you even asking it to get logical AND of, because in the operator precedence table if you see, & is given precedence over < or > operators. Here's the table from from lowest precedence to highest precedence.

It's not even performing the < and > operation and being asked to perform a logical AND operation. So that's why it gives that error.

One can check out the following link to learn more about: operator precedence

Now to Case 2:

If you do use the bracket, you clearly see what happens.

np.where( (ar>3) & (ar<6), 'yo', ar)
np.where( (array([False,  True,  True,  True, False,  True, False,  True])) & (array([ True,  True,  True, False,  True,  True,  True, False])), 'yo', ar)

Two arrays of True and False. And you can easily perform logical AND operation on them. Which gives you:

np.where( array([False,  True,  True, False, False,  True, False, False]),  'yo', ar)

And rest you know, np.where, for given cases, wherever True, assigns first value(i.e. here 'yo') and if False, the other(i.e. here, keeping the original).

That's all. I hope I explained the query well.

The only other thing I would add is to make it a tad more flexible. Most times I'll have a trivial java file I want to run like - Main.java, Simple.java, Example.java, or Playground.java (you get the idea).

I use the following to strike off a javac and corresponding java.

@echo off
javac %~n1.java
java %~n1

The %~n1 gets the filename (sans extension) of the first argument passed to the batch file. So this way I can run it using tab completion and not have to worry about it working with either the .class or .java extension.

So both of the following will have the same result:

run.bat Main.class
and
run.bat Main.java

Doesn't 100% answer the original posters question, but I think it is a good next step/evolution for simple javac/java programs.

var str = "Hello, this is Mike (example)";

alert(str.replace(/\s*\(.*?\)\s*/g, ''));

That'll also replace excess whitespace before and after the parentheses.

I know that question is a bit old but

In root of project where Pipfile is located you could run

pipenv --venv

which returns

/Users/your_user_name/.local/share/virtualenvs/model-N-S4uBGU

and then remove this env by typing

rm -rf /Users/your_user_name/.local/share/virtualenvs/model-N-S4uBGU

Set the breakpoint as you do normally, right click the break point and select condion option and sets your condition.

This answer is not remote server but local server. The logic should be the same. To copy and backup my local machine MAMP database to my local desktop machine folder, go to console then

mysqldump -h YourHostName -u YourUserNameHere -p YourDataBaseNameHere > DestinationPath/xxxwhatever.sql

In my case YourHostName was localhost. DestinationPath is the path to the download; you can drag and drop your desired destination folder and it will paste the path in.

Then password may be asked:

Enter password: xxxxxxxx

echo date('Y',strtotime("-1 year"));        //last year<br>
echo date('d',strtotime("-1 day"));     //last day<br>
echo date('m',strtotime("-1 month"));       //last month<br>

I've had a go at putting together a multiprocessing example of file text searching. This is my first effort at using the multiprocessing module; and I'm a python n00b. Comments quite welcome. I'll have to wait until at work to test on really big files. It should be faster on multi core systems than single core searching. Bleagh! How do I stop the processes once the text has been found and reliably report line number?

import multiprocessing, os, time
NUMBER_OF_PROCESSES = multiprocessing.cpu_count()

def FindText( host, file_name, text):
    file_size = os.stat(file_name ).st_size 
    m1 = open(file_name, "r")

    #work out file size to divide up to farm out line counting

    chunk = (file_size / NUMBER_OF_PROCESSES ) + 1
    lines = 0
    line_found_at = -1

    seekStart = chunk * (host)
    seekEnd = chunk * (host+1)
    if seekEnd > file_size:
        seekEnd = file_size

    if host > 0:
        m1.seek( seekStart )
        m1.readline()

    line = m1.readline()

    while len(line) > 0:
        lines += 1
        if text in line:
            #found the line
            line_found_at = lines
            break
        if m1.tell() > seekEnd or len(line) == 0:
            break
        line = m1.readline()
    m1.close()
    return host,lines,line_found_at

# Function run by worker processes
def worker(input, output):
    for host,file_name,text in iter(input.get, 'STOP'):
        output.put(FindText( host,file_name,text ))

def main(file_name,text):
    t_start = time.time()
    # Create queues

You would need to do something like this. I am typing this off the top of my head, so this may not be 100% correct.

CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef context = CGBitmapContextCreate(NULL, 640, 360, 8, 4 * width, colorSpace, kCGImageAlphaPremultipliedFirst); CGColorSpaceRelease(colorSpace);  CGContextDrawImage(context, CGRectMake(0,-160,640,360), cgImgFromAVCaptureSession);  CGImageRef image = CGBitmapContextCreateImage(context); UIImage* myCroppedImg = [UIImage imageWithCGImage:image]; CGContextRelease(context);       

<form action="" method="POST" enctype="multipart/form-data">
  Select image to upload:
  <input type="file"   name="file[]" multiple/>
  <input type="submit" name="submit" value="Upload Image" />
</form>

Using FOR Loop

<?php    
  $file_dir  = "uploads";    
  if (isset($_POST["submit"])) {

    for ($x = 0; $x < count($_FILES['file']['name']); $x++) {               

      $file_name   = $_FILES['file']['name'][$x];
      $file_tmp    = $_FILES['file']['tmp_name'][$x];

      /* location file save */
      $file_target = $file_dir . DIRECTORY_SEPARATOR . $file_name; /* DIRECTORY_SEPARATOR = / or \ */

      if (move_uploaded_file($file_tmp, $file_target)) {                        
        echo "{$file_name} has been uploaded. <br />";                      
      } else {                      
        echo "Sorry, there was an error uploading {$file_name}.";                               
      }                 

    }               
  }    
?>

Using FOREACH Loop

<?php
  $file_dir  = "uploads";    
  if (isset($_POST["submit"])) {

    foreach ($_FILES['file']['name'] as $key => $value) {                   

      $file_name   = $_FILES['file']['name'][$key];
      $file_tmp    = $_FILES['file']['tmp_name'][$key];

      /* location file save */
      $file_target = $file_dir . DIRECTORY_SEPARATOR . $file_name; /* DIRECTORY_SEPARATOR = / or \ */

      if (move_uploaded_file($file_tmp, $file_target)) {                        
        echo "{$file_name} has been uploaded. <br />";                      
      } else {                      
        echo "Sorry, there was an error uploading {$file_name}.";                               
      }                 

    }               
  }

Here's what I used in Oracle SQL to see if someone was passing a correctly formatted phone number:

WHERE REPLACE(TRANSLATE('555-555-1212','0123456789-','00000000000'),'0','') IS NULL AND
LENGTH(REPLACE(TRANSLATE('555-555-1212','0123456789','0000000000'),'0','')) = 2

The first part checks to see if the phone number has only numbers and the hyphen and the second part checks to see that the phone number has only two hyphens.

AdventureWorksDataContext db = new AdventureWorksDataContext();
db.Log = Console.Out;

// Get hte first customer record
Customer c = from cust in db.Customers select cust where id = 5;
Console.WriteLine(c.CustomerType);
c.CustomerType = 'I';
db.SubmitChanges(); // Save the changes away

This is Working for me

$().popover({container: 'body'})

That can be done in short as:

Model::pluck('column')

where model is the Model such as User model & column as column name like id

if you do

User::pluck('id') // [1,2,3, ...]

& of course you can have any other clauses like where clause before pluck

all answers are great but I just want to give you a good example

select replace('this value from table', 'table',  'table but updated')

this SQL statement will replace the existence of the word "table" (second parameter) inside the given statement(first parameter) with the third parameter

the initial value is this value from table but after executing replace function it will be this value from table but updated

and here is a real example

UPDATE publication
SET doi = replace(doi, '10.7440/perifrasis', '10.25025/perifrasis')
WHERE doi like '10.7440/perifrasis%'

for example if we have this value

10.7440/perifrasis.2010.1.issue-1

it will become

10.25025/perifrasis.2010.1.issue-1

hope this gives you better visualization

If your code is:

<input type="text" id="mytext"/>

And If you are using JQuery, You can use this too:

<script>
function setFocusToTextBox(){
    $("#mytext").focus();
}
</script>

Keep in mind that you must draw the input first $(document).ready()

Yes there is 2MB max and it can be increased by configuration change like this. If your POST body is not in form of multipart file then you might need to add the max-http-post configuration for tomcat in the application yml configuration file.

Increase max size of each multipart file to 10MB and total payload size of 100MB max

 spring:
    servlet:
      multipart:max-file-size: 10MB
      multipart:max-request-size: 100MB
 

Setting max size of post requests which might just be the formdata in string format to ~10 MB

 server:
    tomcat:
        max-http-post-size: 100000000 # max-http-form-post-size: 10MB for new version

You might need to add this for the latest sprintboot version ->

server: tomcat: max-http-form-post-size: 10MB

You can use BOOL, BOOLEAN data type for storing boolean values.

These types are synonyms for TINYINT(1)

However, the BIT(1) data type makes more sense to store a boolean value (either true[1] or false[0]) but TINYINT(1) is easier to work with when you're outputting the data, querying and so on and to achieve interoperability between MySQL and other databases. You can also check this answer or thread.

MySQL also converts BOOL, BOOLEAN data types to TINYINT(1).

Further, read documentation

This is how you should be using mysql_fetch_assoc():

$result = mysql_query($query);

while ($row = mysql_fetch_assoc($result)) {
    // Do stuff with $row
}

$result should be a resource. Even if the query returns no rows, $result is still a resource. The only time $result is a boolean value, is if there was an error when querying the database. In which case, you should find out what that error is by using mysql_error() and ensure that it can't happen. Then you don't have to hide from any errors.

You should always cover the base that errors may happen by doing:

if (!$result) {
    die(mysql_error());
}

At least then you'll be more likely to actually fix the error, rather than leave the users with a glaring ugly error in their face.

For changing particular single column font size use following statement

DataGridView.Columns[1].DefaultCellStyle.Font = new Font("Verdana", 16, FontStyle.Bold);

I just ran into this problem myself.

First, modify your code slightly:

var download = "<?xml version=\"1.0\" encoding=\"utf-8\"?>"
                  +"<"+this.gamesave.tagName+">"
                  +this.xml.firstChild.innerHTML
                  +"</"+this.gamesave.tagName+">";

this.loader.src = "data:application/x-forcedownload;base64,"+
                  btoa(download);

Then use your favorite web inspector, put a breakpoint on the line of code that assigns this.loader.src, then execute this code:

for (var i = 0; i < download.length; i++) {
  if (download[i].charCodeAt(0) > 255) {
    console.warn('found character ' + download[i].charCodeAt(0) + ' "' + download[i] + '" at position ' + i);
  }
}

Depending on your application, replacing the characters that are out of range may or may not work, since you'll be modifying the data. See the note on MDN about unicode characters with the btoa method:

https://developer.mozilla.org/en-US/docs/Web/API/window.btoa

You can simply 'add' the arrays:

>> $a = array(1, 2, 3);
array (
  0 => 1,
  1 => 2,
  2 => 3,
)
>> $b = array("a" => 1, "b" => 2, "c" => 3)
array (
  'a' => 1,
  'b' => 2,
  'c' => 3,
)
>> $a + $b
array (
  0 => 1,
  1 => 2,
  2 => 3,
  'a' => 1,
  'b' => 2,
  'c' => 3,
)

After much research, in many different devices, up to now, I've reached the simple conclusion that MP4 is much less supported than MOV format. So, I'm using MOV format, which is supported by all Android and Apple devices, on all browsers. I've detected weather the device is a mobile device or a desktop browser, and set the SRC accordingly:

if (IsMobile()) {
    $('#vid').attr('src', '/uploads/' + name + '.mov');
}
else {
    $('#vid').attr('src', '/uploads/' + name + '.webm');        
}

function IsMobile() {
    var isMobile = false; //initiate as false

Now there is a released PyPi module for customizable colored logging output:

https://pypi.python.org/pypi/rainbow_logging_handler/

and

https://github.com/laysakura/rainbow_logging_handler

• Supports Windows

• Supports Django

• Customizable colors

As this is distributed as a Python egg, it is very easy to install for any Python application.

You can index and use a negative sign to drop the 3rd column:

data[,-3]

Or you can list only the first 2 columns:

data[,c("c1", "c2")]
data[,1:2]

Don't forget the comma and referencing data frames works like this: data[row,column]

double TotalPrice=90.98989898898;

  DecimalFormat format_2Places = new DecimalFormat("0.00");

    TotalPrice = Double.valueOf(format_2Places.format(TotalPrice));

Relative Path is also ok:

java -Dlog4j.configuration=file:".\log4j.properties" -jar com.your-1.0-SNAPSHOT.jar

or

java -Dlog4j.configuration=file:".\log4j.xml" -jar com.your-1.0-SNAPSHOT.jar

in the below method:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    if (([array count]*65) > [UIScreen mainScreen].bounds.size.height - 66)
    {
        Table.frame = CGRectMake(0, 66, self.view.frame.size.width, [array count]*65)); 
    }
    else
    {
        Table.frame = CGRectMake(0, 66, self.view.frame.size.width, [UIScreen mainScreen].bounds.size.height - 66);
    }
    return [array count];
}

here 65 is the height of the cell and 66 is the height of the navigation bar in UIViewController.

Just use the ES6 find() function in a functional way:

var data=[{name:"Afghanistan",code:"AF"},{name:"Åland Islands",code:"AX"},{name:"Albania",code:"AL"},{name:"Algeria",code:"DZ"}];

let country = data.find(el => el.code === "AL");
// => {name: "Albania", code: "AL"}
console.log(country["name"]);

or Lodash _.find:

var data=[{name:"Afghanistan",code:"AF"},{name:"Åland Islands",code:"AX"},{name:"Albania",code:"AL"},{name:"Algeria",code:"DZ"}];

let country = _.find(data, ["code", "AL"]);
// => {name: "Albania", code: "AL"}
console.log(country["name"]);

<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.11/lodash.min.js"></script>

You can get value of id,name or value in this way. class name my_class

 var id_value = $('.my_class').$(this).attr('id'); //get id value
 var name_value = $('.my_class').$(this).attr('name'); //get name value
 var value = $('.my_class').$(this).attr('value'); //get value any input or tag

1. Go to Gradle tab in Android Studio , then select library project .

2. Then go to Tasks

3. Then go to Other

4. Double click on bundleReleaseaar

You can find your .aar files under your_module/build/outputs/aar/your-release.aar

To improve the solution proposed by @Maxim using $broadcast, send data don't change

$rootScope.$broadcast('SOME_TAG', 'my variable');

but to listening data

$scope.$on('SOME_TAG', function(event, args) {
    console.log("My variable is", args);// args is value of your variable
})

I wanted to provide a solution based on the answer of @kopelitsa. The main differences being:

1. Reusing the controller exception handling by using the HandlerExceptionResolver.
2. Using Java config over XML config

First, you need to make sure, that you have a class that handles exceptions occurring in a regular RestController/Controller (a class annotated with @RestControllerAdvice or @ControllerAdvice and method(s) annotated with @ExceptionHandler). This handles your exceptions occurring in a controller. Here is an example using the RestControllerAdvice:

@RestControllerAdvice
public class ExceptionTranslator {

    @ExceptionHandler(RuntimeException.class)
    @ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
    public ErrorDTO processRuntimeException(RuntimeException e) {
        return createErrorDTO(HttpStatus.INTERNAL_SERVER_ERROR, "An internal server error occurred.", e);
    }

    private ErrorDTO createErrorDTO(HttpStatus status, String message, Exception e) {
        (...)
    }
}

To reuse this behavior in the Spring Security filter chain, you need to define a Filter and hook it into your security configuration. The filter needs to redirect the exception to the above defined exception handling. Here is an example:

@Component
public class FilterChainExceptionHandler extends OncePerRequestFilter {

    private final Logger log = LoggerFactory.getLogger(getClass());

    @Autowired
    @Qualifier("handlerExceptionResolver")
    private HandlerExceptionResolver resolver;

    @Override
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain)
            throws ServletException, IOException {

        try {
            filterChain.doFilter(request, response);
        } catch (Exception e) {
            log.error("Spring Security Filter Chain Exception:", e);
            resolver.resolveException(request, response, null, e);
        }
    }
}

The created filter then needs to be added to the SecurityConfiguration. You need to hook it into the chain very early, because all preceding filter's exceptions won't be caught. In my case, it was reasonable to add it before the LogoutFilter. See the default filter chain and its order in the official docs. Here is an example:

@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Autowired
    private FilterChainExceptionHandler filterChainExceptionHandler;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .addFilterBefore(filterChainExceptionHandler, LogoutFilter.class)
            (...)
    }

}

I have created this simple function which you guys can use easily. You will need to pass the table-name ($tbl), table-field ($insertFieldsArr) against your inserting data, data array ($arr).

insert_batch('table',array('field1','field2'),$dataArray);

    function insert_batch($tbl,$insertFieldsArr,$arr){ $sql = array(); 
    foreach( $arr as $row ) {
        $strVals='';
        $cnt=0;
        foreach($insertFieldsArr as $key=>$val){
            if(is_array($row)){
                $strVals.="'".mysql_real_escape_string($row[$cnt]).'\',';
            }
            else{
                $strVals.="'".mysql_real_escape_string($row).'\',';
            }
            $cnt++;
        }
        $strVals=rtrim($strVals,',');
        $sql[] = '('.$strVals.')';
    }

    $fields=implode(',',$insertFieldsArr);
    mysql_query('INSERT INTO `'.$tbl.'` ('.$fields.') VALUES '.implode(',', $sql));
}

Also you can use the following

@"Italian naval...<br><br>"+

Above code you can achieve double space. If you want single one means you simply use

Applying the full_extent() function in an answer by @Joe 3 years later from here, you can get exactly what the OP was looking for. Alternatively, you can use Axes.get_tightbbox() which gives a little tighter bounding box

import matplotlib.pyplot as plt
import matplotlib as mpl
import numpy as np
from matplotlib.transforms import Bbox

def full_extent(ax, pad=0.0):
    """Get the full extent of an axes, including axes labels, tick labels, and
    titles."""
    # For text objects, we need to draw the figure first, otherwise the extents
    # are undefined.
    ax.figure.canvas.draw()
    items = ax.get_xticklabels() + ax.get_yticklabels() 
#    items += [ax, ax.title, ax.xaxis.label, ax.yaxis.label]
    items += [ax, ax.title]
    bbox = Bbox.union([item.get_window_extent() for item in items])

    return bbox.expanded(1.0 + pad, 1.0 + pad)

# Make an example plot with two subplots...
fig = plt.figure()
ax1 = fig.add_subplot(2,1,1)
ax1.plot(range(10), 'b-')

ax2 = fig.add_subplot(2,1,2)
ax2.plot(range(20), 'r^')

# Save the full figure...
fig.savefig('full_figure.png')

# Save just the portion _inside_ the second axis's boundaries
extent = full_extent(ax2).transformed(fig.dpi_scale_trans.inverted())
# Alternatively,
# extent = ax.get_tightbbox(fig.canvas.renderer).transformed(fig.dpi_scale_trans.inverted())
fig.savefig('ax2_figure.png', bbox_inches=extent)

I'd post a pic but I lack the reputation points

Here a working fiddle: http://jsfiddle.net/sjh36otu/

        function add_number() {

            var first_number = parseInt(document.getElementById("Text1").value);
            var second_number = parseInt(document.getElementById("Text2").value);
            var result = first_number + second_number;

            document.getElementById("txtresult").value = result;
        }

Adding Json.stringfy around the json that fixed the issue

you can return 2 or more values to a function in VBA or any other visual basic stuff but you need to use the pointer method called Byref. See my example below. I will make a function to add and subtract 2 values say 5,6

sub Macro1
    ' now you call the function this way
    dim o1 as integer, o2 as integer
    AddSubtract 5, 6, o1, o2
    msgbox o2
    msgbox o1
end sub


function AddSubtract(a as integer, b as integer, ByRef sum as integer, ByRef dif as integer)
    sum = a + b
    dif = b - 1
end function

A pretty simple solution is to check for the screen width. Since almost all mobile devices have a max screen width of 480px (at present), it's pretty reliable:

if( screen.width <= 480 ) {
    location.href = '/mobile.html';
}

The user-agent string is also a place to look. However, the former solution is still better since even if some freaking device does not respond correctly for the user-agent, the screen width doesn't lie.

The only exception here are tablet pc's like the ipad. Those devices have a higher screen width than smartphones and I would probably go with the user-agent-string for those.

Just grab the file date modified from file system. In my language that is:

 tbl_updated = file.update_time(
        "C:\ProgramData\MySQL\MySQL Server 5.5\data\mydb\person.frm")

Output:

1/25/2013 06:04:10 AM

As per MSDN, In a case of spreadsheets inside of Excel it might not work because Excel files are not real databases. So you will be not able to get the sheets name in order of their visualization in workbook.

Code to get sheets name as per their visual appearance using interop:

Add reference to Microsoft Excel 12.0 Object Library.

Following code will give the sheets name in the actual order stored in workbook, not the sorted name.

Sample Code:

using Microsoft.Office.Interop.Excel;

string filename = "C:\\romil.xlsx";

object missing = System.Reflection.Missing.Value;

Microsoft.Office.Interop.Excel.Application excel = new Microsoft.Office.Interop.Excel.Application();

Microsoft.Office.Interop.Excel.Workbook wb =excel.Workbooks.Open(filename,  missing,  missing,  missing,  missing,missing,  missing,  missing,  missing,  missing,  missing,  missing,  missing,  missing,  missing);

ArrayList sheetname = new ArrayList();

foreach (Microsoft.Office.Interop.Excel.Worksheet  sheet in wb.Sheets)
{
    sheetname.Add(sheet.Name);
}

The right combination of Windows SDK Version and Platform Toolset needs to be selected Depends of course what toolset you have currently installed

The answer on modifying was correct. Yet, I think it should be mentioned that /var/lib/jenkins/config.xml looks something like this if you have activated "Project-based Matrix Authorization Strategy". Deleting /var/lib/jenkins/config.xml and restarting jenkins also does the trick. I also deleted the users in /var/lib/jenkins/users to start from scratch.

<authorizationStrategy class="hudson.security.ProjectMatrixAuthorizationStrategy">

If you need to target multiple classes use:

#main_text .title, #main_text .title2 {
  /* Properties */
}

According to this documentation (a place full of goodies:)):

driver.current_url

or, see official documentation: https://seleniumhq.github.io/docs/site/en/webdriver/browser_manipulation/#get-current-url

My solution (vb.net):

Private Function ConvertToBoolean(p1 As Object) As Boolean
    If p1 Is Nothing Then Return False
    If IsDBNull(p1) Then Return False
    If p1.ToString = "1" Then Return True
    If p1.ToString.ToLower = "true" Then Return True
    Return False
End Function

$myvar = if ($env:variable) { $env:variable } else { "default_value" } 

Your JavaScript is correct. Your button has type="submit" which is causing the page to refresh.

You can use scroll-behavior: smooth; to get this done without Javascript

https://developer.mozilla.org/en-US/docs/Web/CSS/scroll-behavior

In Windows Forms:

this.StartPosition = FormStartPosition.CenterScreen;

In WPF:

this.WindowStartupLocation = WindowStartupLocation.CenterScreen;

That's all you have to do...

Here's how you'd do it if you were using C++ TR1.

Use a regular expression for .replace().:

messagetoSend = messagetoSend.replace(/\n/g, "<br />");

If those linebreaks were made by windows-encoding, you will also have to replace the carriage return.

messagetoSend = messagetoSend.replace(/\r\n/g, "<br />");

I have this code:

<html>_x000D_
<head>_x000D_
<SCRIPT type=text/javascript>_x000D_
function deshabilitarBoton() {     _x000D_
    document.getElementById("boton").style.display = 'none';_x000D_
    document.getElementById("envio").innerHTML ="<br><img src='img/loading.gif' width='16' height='16' border='0'>Generando...";     _x000D_
    return true;_x000D_

<div id="boton">_x000D_
   <input type="submit" name="event" value="Enviar" class="button" onclick="return deshabilitarBoton()" />_x000D_

If I understand your question correctly, I've made a fiddle that has this working correctly. This issue is with how you're assigning the event handlers and as others have said you have over riding event handlers. The current jQuery best practice is to use on() to register event handlers. Here's a link to the jQuery docs about on: link

Your original solution was pretty close but the way you added the event handlers is a bit confusing. It's considered best practice to not add events to HTML elements. I recommend reading up on Unobstrusive JavaScript.

Here's the JavaScript code. I added a counter variable so you can see that it is working correctly.

$('#answer').on('click', function() {
  feedback('hey there');
});

var counter = 0;

function feedback(message) {

  $('#feedback').remove();

  $('.answers').append('<div id="feedback">' + message + ' ' + counter + '</div>');

  counter++;    
}

You need to do the combination of Kristo's answer and MSN's:

// Note: Using the pre-increment operator is preferred for iterators because
//       there can be a performance gain.
//
// Note: As long as you are iterating from beginning to end, without inserting
//       along the way you can safely save end once; otherwise get it at the
//       top of each loop.

std::list< item * >::iterator iter = items.begin();
std::list< item * >::iterator end  = items.end();

while (iter != end)
{
    item * pItem = *iter;

    if (pItem->update() == true)
    {
        other_code_involving(pItem);
        ++iter;
    }
    else
    {
        // BTW, who is deleting pItem, a.k.a. (*iter)?
        iter = items.erase(iter);
    }
}

Of course, the most efficient and SuperCool® STL savy thing would be something like this:

// This implementation of update executes other_code_involving(Item *) if
// this instance needs updating.
//
// This method returns true if this still needs future updates.
//
bool Item::update(void)
{
    if (m_needsUpdates == true)
    {
        m_needsUpdates = other_code_involving(this);
    }

    return (m_needsUpdates);
}

// This call does everything the previous loop did!!! (Including the fact
// that it isn't deleting the items that are erased!)
items.remove_if(std::not1(std::mem_fun(&Item::update)));

select * from employee_list order by salary desc limit 2;

declare class & nested struct probably in some header file

class C {
    // struct will be private without `public:` keyword
    struct S {
        // members will be public without `private:` keyword
        int sa;
        void func();
    };
    void func(S s);
};

if you want to separate the implementation/definition, maybe in some CPP file

void C::func(S s) {
    // implementation here
}
void C::S::func() { // <= note that you need the `full path` to the function
    // implementation here
}

if you want to inline the implementation, other answers will do fine.

Making it invisible with visibility still makes it use up space. Rather try set the display to none to make it invisible, and then set the display to block to make it visible.

In this specific case, the ToString() will return the name of the object retruned by the SelectedCell Property.( a collection of the currently selected cells).

This behavior occurs when an object has no specific implenetation for the ToString() methods.

in our case, all you have to do is to iterate the collection of the cells and to accumulate its values to a string. then push this string to the TextBox.

have a look here how to implement the iteration:

msdn

bootstrap comes with clas btn-lg http://getbootstrap.com/components/#btn-dropdowns-sizing

<div class="btn btn-default btn-block">
  Active
</div>

but if you want to have the button of the width of your column / container add btn-block

<div class="btn btn-default btn-lg">
      Active
    </div>

However this will expand to 100% so make surt ethat you will wrap your button in certain amount of columns e.g. then you know its always stays 3 columns until xs screen

<div class="col-sm-3">
             <div class="btn btn-default btn-block">
          Active
            </div>
        </div>

I've mostly just seen the builtin ValueError used in this situation.

Make sure right depency is selected. File > Project Structure

Select your project and navigate to Dependencies tab. Select right dependancy from dropdown or create new.

If you take a look at @types/node-fetch you will see the body definition

export class Body {
    bodyUsed: boolean;
    body: NodeJS.ReadableStream;
    json(): Promise<any>;
    json<T>(): Promise<T>;
    text(): Promise<string>;
    buffer(): Promise<Buffer>;
}

That means that you could use generics in order to achieve what you want. I didn't test this code, but it would looks something like this:

import { Actor } from './models/actor';

fetch(`http://swapi.co/api/people/1/`)
      .then(res => res.json<Actor>())
      .then(res => {
          let b:Actor = res;
      });

<?php
$data = /** whatever you're serializing **/;
header("Content-type: application/json; charset=utf-8");
echo json_encode($data);
?>

this worked for me:

Private Function arrIsEmpty(arr as variant)
    On Error Resume Next
    arrIsEmpty = False
    arrIsEmpty = IsNumeric(UBound(arr))
End Function

You should be able to declare a cursor to be a bind variable (called parameters in other DBMS')

like Vincent wrote, you can do something like this:

begin
  open :yourCursor
    for 'SELECT "'|| :someField ||'" from yourTable where x = :y'
      using :someFilterValue;
end;

You'd have to bind 3 vars to that script. An input string for "someField", a value for "someFilterValue" and an cursor for "yourCursor" which has to be declared as output var.

Unfortunately, I have no idea how you'd do that from C++. (One could say fortunately for me, though. ;-) )

Depending on which access library you use, it might be a royal pain or straight forward.

git reset --soft origin/my_remote_tracking_branch

This way you will not loose your local changes

You could use a string stream and read the elements into the vector.

Here are many different examples...

A copy of one of the examples:

std::vector<std::string> split(const std::string& s, char seperator)
{
   std::vector<std::string> output;

    std::string::size_type prev_pos = 0, pos = 0;

    while((pos = s.find(seperator, pos)) != std::string::npos)
    {
        std::string substring( s.substr(prev_pos, pos-prev_pos) );

        output.push_back(substring);

        prev_pos = ++pos;
    }

    output.push_back(s.substr(prev_pos, pos-prev_pos)); // Last word

    return output;
}

Try this.

ALTER PROCEDURE [dbo].[sp_ClientNotes_update]
    @id uniqueidentifier,
    @ordering smallint = NULL,
    @title nvarchar(20) = NULL,
    @content text = NULL
AS
BEGIN
    SET NOCOUNT ON;
    UPDATE tbl_ClientNotes
    SET ordering=ISNULL(@ordering,ordering), 
        title=ISNULL(@title,title), 
        content=ISNULL(@content, content)
    WHERE id=@id
END

It might also be worth adding an extra part to the WHERE clause, if you use transactional replication then it will send another update to the subscriber if all are NULL, to prevent this.

WHERE id=@id AND (@ordering IS NOT NULL OR
                  @title IS NOT NULL OR
                  @content IS NOT NULL)

Just put ${yourpathtofile/folder}

PowerShell does not count spaces; to tell PowerShell to consider the whole path including spaces, add your path in between ${ & }.

A ListView let you define a set of views for it and gives you a native way (WPF binding support) to control the display of ListView by using defined views.

Example:

XAML

<ListView ItemsSource="{Binding list}" Name="listv" MouseEnter="listv_MouseEnter" MouseLeave="listv_MouseLeave">
        <ListView.Resources>
            <GridView x:Key="one">
                <GridViewColumn Header="ID" >
                    <GridViewColumn.CellTemplate>
                        <DataTemplate>
                            <TextBlock Text="{Binding id}" />
                        </DataTemplate>
                    </GridViewColumn.CellTemplate>
                </GridViewColumn>
                <GridViewColumn Header="Name" >
                    <GridViewColumn.CellTemplate>
                        <DataTemplate>
                            <TextBlock Text="{Binding name}" />
                        </DataTemplate>
                    </GridViewColumn.CellTemplate>
                </GridViewColumn>
            </GridView>
            <GridView x:Key="two">                    
                <GridViewColumn Header="Name" >
                    <GridViewColumn.CellTemplate>
                        <DataTemplate>
                            <TextBlock Text="{Binding name}" />
                        </DataTemplate>
                    </GridViewColumn.CellTemplate>
                </GridViewColumn>
            </GridView>
        </ListView.Resources>
        <ListView.Style>
            <Style TargetType="ListView">
                <Style.Triggers>
                    <DataTrigger Binding="{Binding ViewType}" Value="1">
                        <Setter Property="View" Value="{StaticResource one}" />
                    </DataTrigger>
                </Style.Triggers>
                <Setter Property="View" Value="{StaticResource two}" />
            </Style>
        </ListView.Style>  

Code Behind:

private int viewType;

public int ViewType
{
    get { return viewType; }
    set 
    { 
        viewType = value;
        UpdateProperty("ViewType");
    }
}        

private void listv_MouseEnter(object sender, MouseEventArgs e)
{
    ViewType = 1;
}

private void listv_MouseLeave(object sender, MouseEventArgs e)
{
    ViewType = 2;
}

OUTPUT:

Normal View: View 2 in above XAML

MouseOver View: View 1 in above XAML

If you try to achieve above in a ListBox, probably you'll end up writing a lot more code forControlTempalate/ItemTemplate of ListBox.

To list all local groups which have users assigned to them, use this command:

cut -d: -f1 /etc/group | sort

For more info- > Unix groups, Cut command, sort command

I am using Red Hat Linux and the following command works:

httpd -V

Slightly more concise now with jQuery 1.6+:

var e = jQuery.Event( 'keydown', { which: $.ui.keyCode.ENTER } );

$('input').trigger(e);

(If you're not using jQuery UI, sub in the appropriate keycode instead.)

While you can access global variables without the global keyword, if you want to modify them you have to use the global keyword. For example:

foo = 1
def test():
    foo = 2 # new local foo

def blub():
    global foo
    foo = 3 # changes the value of the global foo

In your case, you're just accessing the list sub.

You can use following formulas.

For Excel 2007 or later:

=IFERROR(VLOOKUP(D3,List!A:C,3,FALSE),"No Match")

For Excel 2003:

=IF(ISERROR(MATCH(D3,List!A:A, 0)), "No Match", VLOOKUP(D3,List!A:C,3,FALSE))

Note, that

• I'm using List!A:C in VLOOKUP and returns value from column ? 3
• I'm using 4th argument for VLOOKUP equals to FALSE, in that case VLOOKUP will only find an exact match, and the values in the first column of List!A:C do not need to be sorted (opposite to case when you're using TRUE).

Here's a canned method that will accept Moment dates or strings or a mixture as inputs and generate an array of dates as Moment dates. If you don't want Moment dates as output then change what the map() method returns.

const moment = require('moment');

// ...

/**
 * @param {string|import('moment').Moment} start
 * @param {string|import('moment').Moment} end
 * @returns {import('moment').Moment[]}
 */
const getDateRange = (start, end) => {
  const s = moment.isMoment(start) ? start : moment(start);
  const e = moment.isMoment(end) ? end : moment(end);
  return [...Array(1 + e.diff(s, 'days')).keys()].map(n => moment(s).add(n, 'days'));
};

There is one more reason for such failure which I came to know when mine failed

• You might be working with a lot of data and your RAM is full

This might not apply in this case but it also throws the same error and since this question comes up on top for this error, I have added this answer here.

The fastest way should be:

<%@ page import="java.util.Map" %>
Map<String, String[]> parameters = request.getParameterMap();
for (Map.Entry<String, String[]> entry : parameters.entrySet()) {
    if (entry.getKey().startsWith("question")) {
        String[] values = entry.getValue();
        // etc.

Note that you can't do:

for (Map.Entry<String, String[]> entry : 
     request.getParameterMap().entrySet()) { // WRONG!

for reasons explained here.

It works:

mysql -u root -p db_name < "C:\folder_name\db_name.sql"

C:\ is for example

If you are using the System.Diagnostics.Debugger.Break(); workaround (which I think is just fine for temporary use) and it's "just not working" on your Windows 8 Machine. The reason is a bug in Visual Studio's "Just in time debugging".

The fix is as follows is to fix the key for the "Visual Studio Just-In-Time Debugger"

Open regedit and go to HKEY_CLASSES_ROOT\AppID{E62A7A31-6025-408E-87F6-81AEB0DC9347} for the ‘AppIDFlags’ registry value, set the flag to 0x8

Dim celltxt As String
Range("C6").Select

celltxt = Selection.Text
If InStr(1, celltext, "TOTAL") > 0 Then
Range("C7").Select 
Selection.End(xlToRight).Select
Selection.Value = "-"
End If

You declared "celltxt" and used "celltext" in the instr.

  if (window.sidebar) { // Mozilla Firefox Bookmark
     window.sidebar.addPanel(document.title,location.href,"");

It adds the bookmark but in the sidebar.

The problem is that .form-control class renders like a DIV element which according to the normal-flow-of-the-page renders on a new line.

One way of fixing issues like this is to use display:inline property. So, create a custom CSS class with display:inline and attach it to your component with a .form-control class. You have to have a width for your component as well.

There are other ways of handling this issue (like arranging your form-control components inside any of the .col classes), but the easiest way is to just make your .form-control an inline element (the way a span would render)

Using the ECMAScript 6 method String#repeat, a pad function is as simple as:

String.prototype.padLeft = function(char, length) { 
    return char.repeat(Math.max(0, length - this.length)) + this;
}

String#repeat is currently supported in Firefox and Chrome only. for other implementation, one might consider the following simple polyfill:

String.prototype.repeat = String.prototype.repeat || function(n){ 
    return n<=1 ? this : (this + this.repeat(n-1)); 
}

As others have said, it's macro recording, and you turn it off with q. Here's a nice article about how-to and why it's useful.

A simple function like below will help :

public string GetCurrentPageName() 
{ 
    string sPath = System.Web.HttpContext.Current.Request.Url.AbsolutePath; 
    System.IO.FileInfo oInfo = new System.IO.FileInfo(sPath); 
    string sRet = oInfo.Name; 
    return sRet; 
} 

For tables you must loop that:

for tbl in `psql -qAt -c "select tablename from pg_tables where schemaname = 'public';" YOUR_DB` ; do  psql -U postgres -c "alter table \"$tbl\" owner to NEW_USER" YOUR_DB ; done

If you use yum search you can find the python dev package for your version of python.

For me I was using python 3.5. I ran the following

yum search python | grep devel

Which returned the following

I was then able to install the correct package for my version of python with the following cmd.

sudo yum install python35u-devel.x86_64

This works on centos for ubuntu or debian you would need to use apt-get
