The File class represents the "idea" of a file, not an actual handle to use for I/O. This is why the File class has a .exists() method, to tell you if the file exists or not. (How can you have a File object that doesn't exist?)

By contrast, constructing a new FileInputStream(new File("/my/file")) gives you an actual stream to read bytes from.

You can combine both in the same date function call

date("d-m-Y H:i:s");  

I got it working in iOS7 using a prototype cell in the storyboard. I have a button in my custom section header view that triggers a segue that is set up in the storyboard.

Start with Tieme's solution

As pedro.m points out, the problem with this is that tapping the section header causes the first cell in the section to be selected.

As Paul Von points out, this is fixed by returning the cell's contentView instead of the whole cell.

However, as Hons points out, a long press on said section header will crash the app.

The solution is to remove any gestureRecognizers from contentView.

-(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
     static NSString *CellIdentifier = @"SectionHeader";
     UITableViewCell *sectionHeaderView = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

     while (sectionHeaderView.contentView.gestureRecognizers.count) {
         [sectionHeaderView.contentView removeGestureRecognizer:[sectionHeaderView.contentView.gestureRecognizers objectAtIndex:0]];
     }

     return sectionHeaderView.contentView; }

If you aren't using gestures in your section header views, this little hack seems to get it done.

How about

session.query(MyUserClass).filter(MyUserClass.id.in_((123,456))).all()

edit: Without the ORM, it would be

session.execute(
    select(
        [MyUserTable.c.id, MyUserTable.c.name], 
        MyUserTable.c.id.in_((123, 456))
    )
).fetchall()

select() takes two parameters, the first one is a list of fields to retrieve, the second one is the where condition. You can access all fields on a table object via the c (or columns) property.

        XmlWriterSettings settings = new XmlWriterSettings
        {
            OmitXmlDeclaration = true
        };

        XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
        ns.Add("", "");

        StringBuilder sb = new StringBuilder();

        XmlSerializer xs = new XmlSerializer(typeof(BankingDetails));

        using (XmlWriter xw = XmlWriter.Create(sb, settings))
        {
            xs.Serialize(xw, model, ns);
            xw.Flush();
            return sb.ToString();
        }

This is my solution:

public class Foo : IDisposable
{
    private event EventHandler _statusChanged;
    public event EventHandler StatusChanged
    {
        add
        {
            _statusChanged += value;
        }
        remove
        {
            _statusChanged -= value;
        }
    }

    public void Dispose()
    {
        _statusChanged = null;
    }
}

You need to call Dispose() or use using(new Foo()){/*...*/} pattern to unsubscribe all members of invocation list.

read -e -p "Enter Your Name:" -i "Ricardo" NAME

so long as your html content doesn't need to contain a CDATA element, you can contain the HTML in a CDATA element, otherwise you'll have to escape the XML entities.

<element><![CDATA[<p>your html here</p>]]></element>

VS

<element>&lt;p&gt;your html here&lt;/p&gt;</element>

Your app is crashing at:

welcomePlayer.setText("Welcome Back, " + String.valueOf(mPlayer.getName(this)) + " !");

because mPlayer=null.

You forgot to initialize Player mPlayer in your PlayGame Activity.

mPlayer = new Player(context,"");

This is just a sample code, but it may help you get on your way:

Public Sub testIt()
    Workbooks("Workbook2").Activate
    ActiveWorkbook.Sheets("Sheet2").Activate
    ActiveSheet.Range("B3").Select
    ActiveCell.EntireRow.Insert
End Sub

I am assuming that you can open the book (called Workbook2 in the example).

I think (but I'm not sure) you can squash all this in a single line of code:

    Workbooks("Workbook2").Sheets("Sheet2").Range("B3").EntireRow.Insert

This way you won't need to activate the workbook (or sheet or cell)... Obviously, the book has to be open.

For text:

[RangeObject].Font.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red);

For cell background

[RangeObject].Interior.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red);

If you want to have a list of characters (a word), you can use char *word

If you want a list of words (a sentence), you can use char **sentence

If you want a list of sentences (a monologue), you can use char ***monologue

If you want a list of monologues (a biography), you can use char ****biography

If you want a list of biographies (a bio-library), you can use char *****biolibrary

If you want a list of bio-libraries (a ??lol), you can use char ******lol

    free(lol);
    free(biolibrary);
    free(biography);
    free(monologue);
    free(sentence);
    free(word);
}

Output:

total words in my lol: 243

To delete a job which has not yet run, you need the atrm command. You can use atq command to get its number in the at list.

To kill a job which has already started to run, you'll need to grep for it using:

ps -eaf | grep <command name>

and then use kill to stop it.

A quicker way to do this on most systems is:

pkill <command name>

Try these:

1. window.location.href = 'http://www.google.com';
2. window.location.assign("http://www.w3schools.com");
3. window.location = 'http://www.google.com';

I have tried several solutions today, the one working best for me is Jo-Geek/jQuery-ResizableColumns. Is is very simple, yet it handles tables placed in flex containers, which many of the other ones fail with.

<table class="resizable">
</table>

$('table.resizable').resizableColumns();

$(function() {_x000D_
  $('table.resizable').resizableColumns();_x000D_
})

body {_x000D_
  margin: 0px;_x000D_
}_x000D_
_x000D_
table {_x000D_
  width: 100%;_x000D_
  table-layout: fixed;_x000D_
  border-collapse: collapse;_x000D_
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<script src="https://jo-geek.github.io/jQuery-ResizableColumns/demo/resizableColumns.min.js"></script>_x000D_

Use val() instead of text()

var hv = $('#h_v').val();
alert(hv);

You had these problems:

• Single quotes was not closed
• You were using text() for an input field
• You were echoing x rather than variable hv

For the convenience of usage, I sum up the note of striping punctuation from a string in both Python 2 and Python 3. Please refer to other answers for the detailed description.

Python 2

import string

s = "string. With. Punctuation?"
table = string.maketrans("","")
new_s = s.translate(table, string.punctuation)      # Output: string without punctuation

Python 3

import string

s = "string. With. Punctuation?"
table = str.maketrans(dict.fromkeys(string.punctuation))  # OR {key: None for key in string.punctuation}
new_s = s.translate(table)                          # Output: string without punctuation

Depending on the libc release it could be needed to set both SO_REUSEADDR and SO_REUSEPORT socket options as explained in socket(7) documentation :

   SO_REUSEPORT (since Linux 3.9)
          Permits multiple AF_INET or AF_INET6 sockets to be bound to an
          identical socket address.  This option must be set on each
          socket (including the first socket) prior to calling bind(2)
          on the socket.  To prevent port hijacking, all of the
          processes binding to the same address must have the same
          effective UID.  This option can be employed with both TCP and
          UDP sockets.

As this socket option appears with kernel 3.9 and raspberry use 3.12.x, it will be needed to set SO_REUSEPORT.

You can set theses two options before calling bind like this :

    int reuse = 1;
    if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEADDR, (const char*)&reuse, sizeof(reuse)) < 0)
        perror("setsockopt(SO_REUSEADDR) failed");

#ifdef SO_REUSEPORT
    if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEPORT, (const char*)&reuse, sizeof(reuse)) < 0) 
        perror("setsockopt(SO_REUSEPORT) failed");
#endif

For those still looking for a simple answer, check out git cherry. It compares actual diffs instead of commit hashes. That means it accommodates commits that have been cherry picked or rebased.

First checkout the branch you want to delete:

git checkout [branch-to-delete]

then use git cherry to compare it to your main development branch:

git cherry -v master

Example output:

+ 8a14709d08c99c36e907e47f9c4dacebeff46ecb Commit message
+ b30ccc3fb38d3d64c5fef079a761c7e0a5c7da81 Another commit message
- 85867e38712de930864c5edb7856342e1358b2a0 Yet another message

Note: The -v flag is to include the commit message along with the SHA hash.

Lines with the '+' in front are in the branch-to-delete, but not the master branch. Those with a '-' in front have an equivalent commit in master.

For JUST the commits that aren't in master, combine cherry pick with grep:

git cherry -v master | grep "^\+"

Example output:

+ 8a14709d08c99c36e907e47f9c4dacebeff46ecb Commit message
+ b30ccc3fb38d3d64c5fef079a761c7e0a5c7da81 Another commit message

It has to be made clear the HTTP protocol is synchronous and this has nothing to do with the programming language. Client sends a request and gets a synchronous response.

If you want to an asynchronous behavior over HTTP, this has to be built over HTTP (I don't know anything about ActionScript but I suppose that this is what the ActionScript does too). There are many libraries that could give you such functionality (e.g. Jersey SSE). Note that they do somehow define dependencies between the client and the server as they do have to agree on the exact non standard communication method above HTTP.

If you cannot control both the client and the server or if you don't want to have dependencies between them, the most common approach of implementing asynchronous (e.g. event based) communication over HTTP is using the webhooks approach (you can check this for an example implementation in java).

Hope I helped!

The following should work and not require any permissions in the manifest (basically override shouldOverrideUrlLoading and handle links separately from tel, mailto, etc.):

    mWebView = (WebView) findViewById(R.id.web_view);

    WebSettings webSettings = mWebView.getSettings();
    webSettings.setJavaScriptEnabled(true);

    mWebView.setWebViewClient(new WebViewClient(){
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            if( url.startsWith("http:") || url.startsWith("https:") ) {
                return false;
            }

            // Otherwise allow the OS to handle things like tel, mailto, etc.
            Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
            startActivity( intent );
            return true;
        }
    });
    mWebView.loadUrl(url);

Also, note that in the above snippet I am enabling JavaScript, which you will also most likely want, but if for some reason you don't, just remove those 2 lines.

Despite all the explanations, LEA is an arithmetic operation:

LEA Rt, [Rs1+a*Rs2+b] =>  Rt = Rs1 + a*Rs2 + b

It's just that its name is extremelly stupid for a shift+add operation. The reason for that was already explained in the top rated answers (i.e. it was designed to directly map high level memory references).

I'm not sure if I understand your question, but I'll take a stab at it:

td {
    border: 1px solid #000;
}

tr td:last-child {
    width: 1%;
    white-space: nowrap;
}

<table style="width: 100%;">
    <tr>
        <td class="block">this should stretch</td>
        <td class="block">this should stretch</td>
        <td class="block">this should be the content width</td>
    </tr>
</table>

localStorage is something that is kept on the client side. There is no data transmitted to the server side.

You can only get the data with JavaScript and you can send it to the server side with Ajax.

Try this solution:

There is a data item in your table whose associated value doesn't exist in the table you want to use it as a primary key table. Make your table empty or add the associated value to the second table.

You also use this below to expand the memory

export _JAVA_OPTIONS="-Xms512m -Xmx1024m -Xss512m -XX:MaxPermSize=1024m"

Xmx specifies the maximum memory allocation pool for a Java virtual machine (JVM)

Xms specifies the initial memory allocation pool.

Xss setting memory size of thread stack

XX:MaxPermSize: the maximum permanent generation size

This problem happens because you are referencing the same object more than once. This is not a limitation of EF, but rather a safety feature to ensure you are not inserting the same object with two different IDs. So to achieve what you are trying to do, is simply create a new object and add the newly created object to the database.

** This issue often happens inside loops. If you are using a while or foreach loop, make sure to have the New Created Object INSIDE the loop body.

try this:

Contact contact = dbContext.Contacts.Single(c => c.contactTypeId == 1234);
contact.contactTypeId = 4;
dbContext.AddObject(contact);
dbContext.SaveChanges();

DIVs inherently lack any useful meaning, other than to divide, of course.

Best course of action would be to add a meaningful class name to them, and style their individual margins in CSS.

<h1>Important Title</h1>
<div class="testimonials">...</div>
<div class="footer">...</div>

h1 {margin-bottom: 0.1em;}
div.testimonials {margin-bottom: 0.2em;}
div.footer {margin-bottom: 0;}

For ListView item image you can set ImageView.setVisibility(View.INVISIBLE) or ImageView.setImageBitmap(null) in list adapter for "no image" case.

mySelect.value = myValue;

Where mySelect is your selection box, and myValue is the value you want to change it to.

I think the easiest way to do it is by styling a label and making the checkbox invisible.

HTML

<input type="checkbox" id="first" />
<label for="first">&nbsp;</label>

CSS

checkbox {
  display: none;
}

checkbox + label {
  /* Style for checkbox normal */
  width: 16px;
  height: 16px;
}

checkbox::checked + label,
label.checked {
  /* Style for checkbox checked */
}

The checkbox, even though it is hidden, will still be accessible, and its value will be sent when a form is submitted. For old browsers you might have to change the class of the label to checked using JavaScript because I don't think old versions of Internet Explorer understand ::checked on the checkbox.

You could do it in one document if you had a conditional based on params sent over. Eg:

if (isset($_GET['secret_param'])) {
    <run script>
} else {
    <display button>
}

I think the best way though is to have two files.

1. Eclipse -> Top menu -> Run -> Run Configurations
2. Delete all the occurrences of your test. Your test may appear as YourTest.Method_1(). Delete that as well.
3. Re-run. Let Eclipse build a fresh configuration.

Addendum: Locally I have created a "User Library" and added to my projects which has

hamcrest-core-1.3.jar

junit-4.12.jar

Another option in case you don't wanna use a plugin:

Ctrl+` or

View -> Show Console

type on the console the following command:

view.encoding()

In case you want to something more intrusive, there's a option to create an shortcut that executes the following command:

sublime.message_dialog(view.encoding())

The property file task is for editing properties files. It contains all sorts of nice features that allow you to modify entries. For example:

<propertyfile file="build.properties">
    <entry key="build_number"
        type="int"
        operation="+"
        value="1"/>
</propertyfile>

I've incremented my build_number by one. I have no idea what the value was, but it's now one greater than what it was before.

• Use the <echo> task to build a property file instead of <propertyfile>. You can easily layout the content and then use <propertyfile> to edit that content later on.

Example:

<echo file="build.properties">
# Default Configuration
source.dir=1
dir.publish=1
# Source Configuration
dir.publish.html=1
</echo>

• Create separate properties files for each section. You're allowed a comment header for each type. Then, use to batch them together into one single file:

Example:

<propertyfile file="default.properties"
    comment="Default Configuration">
    <entry key="source.dir" value="1"/>
    <entry key="dir.publish" value="1"/>
<propertyfile>

<propertyfile file="source.properties"
    comment="Source Configuration">
    <entry key="dir.publish.html" value="1"/>
<propertyfile>
<concat destfile="build.properties">
    <fileset dir="${basedir}">
        <include name="default.properties"/>
        <include name="source.properties"/>
    </fileset>
</concat>

<delete>
    <fileset dir="${basedir}">
         <include name="default.properties"/>
        <include name="source.properties"/>
    </fileset>
</delete>      

From my understanding matplotlib is a plotting library.

If you want to change the image data (e.g. draw a rectangle on an image), you could use PIL's ImageDraw, OpenCV, or something similar.

Here is PIL's ImageDraw method to draw a rectangle.

Here is one of OpenCV's methods for drawing a rectangle.

Your question asked about Matplotlib, but probably should have just asked about drawing a rectangle on an image.

Here is another question which addresses what I think you wanted to know: Draw a rectangle and a text in it using PIL

The shortcut key is ctrl+] to indentation and ctrl +[ to unindent

I have got inspiration from multiple sources on the internet to derive into the solution below. Wanted to take into account both some default value and to provide a way to compare each entry for a generic approach which this solves.

Usage: (giving value "Second")

var defaultItemValue = { id: -1, name: "Undefined" };
var containers: Container[] = [{ id: 1, name: "First" }, { id: 2, name: "Second" }];
GetContainer(2).name;

Implementation:

class Container {
    id: number;
    name: string;
}

public GetContainer(containerId: number): Container {
  var comparator = (item: Container): boolean => {
      return item.id == containerId;
    };
    return this.Get<Container>(this.containers, comparator, this.defaultItemValue);
  }

private Get<T>(array: T[], comparator: (item: T) => boolean, defaultValue: T): T {
  var found: T = null;
  array.some(function(element, index) {
    if (comparator(element)) {
      found = element;
      return true;
    }
  });

  if (!found) {
    found = defaultValue;
  }

  return found;
}

On OSX, you can take advantage of the UNIX-like command line - here's what I keep handy in my .bashrc to enable me to more easily restart a server that's running in background (-d) mode (note that you have to be in the Rails root directory when running this):

alias restart_rails='kill -9 `cat tmp/pids/server.pid`; rails server -d'

My initial response to the comment by @zane about how the PID file isn't removed was that it might be behavior dependent on the Rails version or OS type. However, it's also possible that the shell runs the second command (rails server -d) sooner than the kill can actually cause the previous running instance to stop.

So alternatively, kill -9 cat tmp/pids/server.pid && rails server -d might be more robust; or you can specifically run the kill, wait for the tmp/pids folder to empty out, then restart your new server.

Why not measure it:

class Program
{
    class NameComparer : IComparer<string>
    {
        public int Compare(string x, string y)
        {
            return string.Compare(x, y, true);
        }
    }

    class Person
    {
        public Person(string id, string name)
        {
            Id = id;
            Name = name;
        }
        public string Id { get; set; }
        public string Name { get; set; }
    }

}

On my computer when compiled in Release mode this program prints:

Sort: 1162ms
OrderBy: 1269ms

UPDATE:

As suggested by @Stefan here are the results of sorting a big list fewer times:

List<Person> persons = new List<Person>();
for (int i = 0; i < 100000; i++)
{
    persons.Add(new Person("P" + i.ToString(), "Janson" + i.ToString()));
}

Sort(persons);
OrderBy(persons);

const int COUNT = 30;
Stopwatch watch = Stopwatch.StartNew();
for (int i = 0; i < COUNT; i++)
{
    Sort(persons);
}
watch.Stop();
Console.WriteLine("Sort: {0}ms", watch.ElapsedMilliseconds);

watch = Stopwatch.StartNew();
for (int i = 0; i < COUNT; i++)
{
    OrderBy(persons);
}
watch.Stop();
Console.WriteLine("OrderBy: {0}ms", watch.ElapsedMilliseconds);

Prints:

Sort: 8965ms
OrderBy: 8460ms

In this scenario it looks like OrderBy performs better.

UPDATE2:

And using random names:

List<Person> persons = new List<Person>();
for (int i = 0; i < 100000; i++)
{
    persons.Add(new Person("P" + i.ToString(), RandomString(5, true)));
}

Where:

private static Random randomSeed = new Random();
public static string RandomString(int size, bool lowerCase)
{
    var sb = new StringBuilder(size);
    int start = (lowerCase) ? 97 : 65;
    for (int i = 0; i < size; i++)
    {
        sb.Append((char)(26 * randomSeed.NextDouble() + start));
    }
    return sb.ToString();
}

Yields:

Sort: 8968ms
OrderBy: 8728ms

Still OrderBy is faster

Use the below format, it would work on all the browsers

var year = 2016;
var month = 02;           // month varies from 0-11 (Jan-Dec)
var day = 23;

month = month<10?"0"+month:month;        // to ensure YYYY-MM-DD format
day = day<10?"0"+day:day;

dateObj = new Date(year+"-"+month+"-"+day);

alert(dateObj); 

//Your output would look like this "Wed Mar 23 2016 00:00:00 GMT+0530 (IST)"

//Note this would be in the current timezone in this case denoted by IST, to convert to UTC timezone you can include

alert(dateObj.toUTCSting);

//Your output now would like this "Tue, 22 Mar 2016 18:30:00 GMT"

Note that now the dateObj shows the time in GMT format, also note that the date and time have been changed correspondingly.

The "toUTCSting" function retrieves the corresponding time at the Greenwich meridian. This it accomplishes by establishing the time difference between your current timezone to the Greenwich Meridian timezone.

In the above case the time before conversion was 00:00 hours and minutes on the 23rd of March in the year 2016. And after conversion from GMT+0530 (IST) hours to GMT (it basically subtracts 5.30 hours from the given timestamp in this case) the time reflects 18.30 hours on the 22nd of March in the year 2016 (exactly 5.30 hours behind the first time).

Further to convert any date object to timestamp you can use

alert(dateObj.getTime());

//output would look something similar to this "1458671400000"

This would give you the unique timestamp of the time

I've experienced the same issue because of certifi library. Installing a different version helped me as well.

If you are looking for generic usage, here is my suggestion:

Create a class named as Run:

class Run {
    companion object {
        fun after(delay: Long, process: () -> Unit) {
            Handler().postDelayed({
                process()
            }, delay)
        }
    }
}

And use like this:

Run.after(1000, {
    // print something useful etc.
})

Apart from using an escaped value as described in my other answer, it is also possible to fix this issue by enabling the Strict Math setting.

With strict math on, only maths that are inside unnecessary parentheses will be processed, so your code:

width: calc(100% - 200px);

Would work as expected with the strict math option enabled.

However, note that Strict Math is applied globally, not only inside calc(). That means, if you have:

font-size: 12px + 2px;

The math will no longer be processed by Less -- it will output font-size: 12px + 2px which is, obviously, invalid CSS. You'd have to wrap all maths that should be processed by Less in (previously unnecessary) parentheses:

font-size: (12px + 2px);

Strict Math is a nice option to consider when starting a new project, otherwise you'd possibly have to rewrite a good part of the code base. For the most common use cases, the escaped string approach described in the other answer is more suitable.

Example of how to output colored messages of level "INFO" or higher to console and messages of level "WARN" or higher to file.

Your logback.xml file:

<?xml version="1.0" encoding="UTF-8"?>

<configuration>
    <include resource="org/springframework/boot/logging/logback/defaults.xml"/>

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <filter class="ch.qos.logback.classic.filter.LevelFilter">
            <level>INFO</level>

            <!--output messages of exact level only-->
            <!--<onMatch>ACCEPT</onMatch>-->
            <!--<onMismatch>DENY</onMismatch>-->
        </filter>
        <encoder>
            <pattern>%d{yyyy-MMM-dd HH:mm:ss.SSS} [%thread] %highlight(%-5level) %cyan(%logger{15}) - %msg %n
            </pattern>
        </encoder>
    </appender>

    <appender name="FILE" class="ch.qos.logback.core.FileAppender">
        <file>myfile.log</file>
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
            <level>WARN</level>
        </filter>
        <append>true</append>
        <encoder>
            <pattern>%d{yyyy-MMM-dd HH:mm:ss.SSS} %-5level [%thread] %logger{15} - %msg%n</pattern>
        </encoder>
    </appender>

    <root level="INFO">
        <appender-ref ref="STDOUT" />
        <appender-ref ref="FILE"/>
    </root>
</configuration>

Using .getActivity() solves this issue:

For eg.

Intent i= new Intent(MainActivity.this.getActivity(), Next.class);
startActivity(i);

Hope this helps.

Cheers.

According to Wikipedia:

The port numbers are defined in RFC 6120 § 14.7.

The EFCore examples on MSDN show that you can do some quite complex things with Include and ThenInclude.

This is a good example of how complex you can get (this is all one chained statement!):

viewModel.Instructors = await _context.Instructors

      .Include(i => i.OfficeAssignment)

      .Include(i => i.CourseAssignments)
        .ThenInclude(i => i.Course)
            .ThenInclude(i => i.Enrollments)
                .ThenInclude(i => i.Student)

      .Include(i => i.CourseAssignments)
        .ThenInclude(i => i.Course)
            .ThenInclude(i => i.Department)

      .AsNoTracking()
      .OrderBy(i => i.LastName)
      .ToListAsync();

You can have multiple Include calls - even after ThenInclude and it kind of 'resets' you back to the level of the top level entity (Instructors).

You can even repeat the same 'first level' collection (CourseAssignments) multiple times followed by separate ThenIncludes commands to get to different child entities.

Note your actual query must be tagged onto the end of the Include or ThenIncludes chain. The following does NOT work:

var query = _context.Instructors.AsQueryable();
query.Include(i => i.OfficeAssignment);

var first10Instructors = query.Take(10).ToArray();

Would strongly recommend you set up logging and make sure your queries aren't out of control if you're including more than one or two things. It's important to see how it actually works - and you'll notice each separate 'include' is typically a new query to avoid massive joins returning redundant data.

AsNoTracking can greatly speed things up if you're not intending on actually editing the entities and resaving.

EFCore 5 made some changes to the way queries for multiple sets of entities are sent to the server. There are new options for Split Queries which can make certain queries of this type far more efficient with fewer joins, but make sure to understand the limitations.

I've resolved this using:

.element:before {
    font-family: "Font Awesome 5 Free" , "CircularStd";
    content: "\f017" " Date";
}

Using the font family "font awesome 5 free" for the icon, and after, We have to specify the font that we are using again because if we doesn't do this, navigator will use the default font (times new roman or something like this).

try this code I think it is more optimal.

HeaderRow is used to repeat the header of the table for each new page automatically

        BaseFont bfTimes = BaseFont.CreateFont(BaseFont.TIMES_ROMAN, BaseFont.CP1252, false);
        iTextSharp.text.Font times = new iTextSharp.text.Font(bfTimes, 6, iTextSharp.text.Font.NORMAL, iTextSharp.text.BaseColor.BLACK);

        PdfPTable table = new PdfPTable(10) { HorizontalAlignment = Element.ALIGN_CENTER, WidthPercentage = 100, HeaderRows = 2 };
        table.SetWidths(new float[] { 2f, 6f, 6f, 3f, 5f, 8f, 5f, 5f, 5f, 5f });
        table.AddCell(new PdfPCell(new Phrase("SER.\nNO.", times)) { Rowspan = 2, GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("TYPE OF SHIPPING", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("ORDER NO.", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("QTY.", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("DISCHARGE PPORT", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("DESCRIPTION OF GOODS", times)) { Rowspan = 2, GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("LINE DOC. RECL DATE", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("CLEARANCE DATE", times)) { Rowspan = 2, GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("CUSTOM PERMIT NO.", times)) { Rowspan = 2, GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("DISPATCH DATE", times)) { Rowspan = 2, GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("AWB/BL NO.", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("COMPLEX NAME", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("G. W. Kgs.", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("DESTINATION", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("OWNER DOC. RECL DATE", times)) { GrayFill = 0.95f });

You may have real characters "\" in the string (the single quote strings, as said @Robik).

If you are quite sure the '\r' or '\n' strings should be replaced as well, I'm not talking of special characters here but a sequence of two chars '\' and 'r', then escape the '\' in the replace string and it will work:

str_replace(array("\r\n","\r","\n","\\r","\\n","\\r\\n"),"<br/>",$description);

Don't!

I know, that's the "answer" nobody wants. But if something's worth doing, it's worth doing right, right?

This seeming like a good idea probably stems from a fairly wide misconception that shell commands such as curl are anything other than programs themselves.

So what you're asking is "how do I run this other program, from within my program, just to make a measly little web request?". That's crazy, there's got to be a better way right?

Uxio's answer works, sure. But it hardly looks very Pythonic, does it? That's a lot of work just for one little request. Python's supposed to be about flying! Anyone writing that is probably wishing they just call'd curl!

it works, but is there a better way?

Yes, there is a better way!

Requests: HTTP for Humans

Things shouldn’t be this way. Not in Python.

Let's GET this page:

import requests
res = requests.get('https://stackoverflow.com/questions/26000336')

That's it, really! You then have the raw res.text, or res.json() output, the res.headers, etc.

You can see the docs (linked above) for details of setting all the options, since I imagine OP has moved on by now, and you - the reader now - likely need different ones.

But, for example, it's as simple as:

url     = 'http://example.tld'
payload = { 'key' : 'val' }
headers = {}
res = requests.post(url, data=payload, headers=headers)

You can even use a nice Python dict to supply the query string in a GET request with params={}.

Simple and elegant. Keep calm, and fly on.

Smart pointers will clean themselves up after they go out of scope (thereby removing fear of most memory leaks). Shared pointers are smart pointers that keep a count of how many instances of the pointer exist, and only clean up the memory when the count reaches zero. In general, only use shared pointers (but be sure to use the correct kind--there is a different one for arrays). They have a lot to do with RAII.

I also had this problem today, and deleting files org.eclipse.jst.server.tomcat.core.prefs and org.eclipse.wst.server.core.prefs didn't work.

Finally I found it's permission issue:

By default <apache-tomcat-version>/conf/* can be read only by owner, after I made it readable for all, it works! So run this command:

chmod a+r <apache-tomcat-version>/conf/*

Here is the link where I found the root cause:

Some people mentioning sc delete as an answer. This is how I did it, but it took me a while to find the <service-name> parameter.

The command sc query type= service (note, it's very particular with formatting, the space before "service" is necessary) will output a list of Windows services installed, complete with their qualified name to be used with sc delete <service-name> command.

The list is quite long so you may consider piping the output to a text file (i.e. >> C:\test.txt) and then searching through that.

The SERVICE_NAME is the one to use with sc delete <service-name> command.

There's no notion of "this class must have these functions" (that is, no interfaces per se), because:

1. JavaScript inheritance is based on objects, not classes. That's not a big deal until you realize:
2. JavaScript is an extremely dynamically typed language -- you can create an object with the proper methods, which would make it conform to the interface, and then undefine all the stuff that made it conform. It'd be so easy to subvert the type system -- even accidentally! -- that it wouldn't be worth it to try and make a type system in the first place.

Instead, JavaScript uses what's called duck typing. (If it walks like a duck, and quacks like a duck, as far as JS cares, it's a duck.) If your object has quack(), walk(), and fly() methods, code can use it wherever it expects an object that can walk, quack, and fly, without requiring the implementation of some "Duckable" interface. The interface is exactly the set of functions that the code uses (and the return values from those functions), and with duck typing, you get that for free.

Now, that's not to say your code won't fail halfway through, if you try to call some_dog.quack(); you'll get a TypeError. Frankly, if you're telling dogs to quack, you have slightly bigger problems; duck typing works best when you keep all your ducks in a row, so to speak, and aren't letting dogs and ducks mingle together unless you're treating them as generic animals. In other words, even though the interface is fluid, it's still there; it's often an error to pass a dog to code that expects it to quack and fly in the first place.

But if you're sure you're doing the right thing, you can work around the quacking-dog problem by testing for the existence of a particular method before trying to use it. Something like

if (typeof(someObject.quack) == "function")
{
    // This thing can quack
}

So you can check for all the methods you can use before you use them. The syntax is kind of ugly, though. There's a slightly prettier way:

Object.prototype.can = function(methodName)
{
     return ((typeof this[methodName]) == "function");
};

if (someObject.can("quack"))
{
    someObject.quack();
}

This is standard JavaScript, so it should work in any JS interpreter worth using. It has the added benefit of reading like English.

For modern browsers (that is, pretty much any browser other than IE 6-8), there's even a way to keep the property from showing up in for...in:

Object.defineProperty(Object.prototype, 'can', {
    enumerable: false,
    value: function(method) {
        return (typeof this[method] === 'function');
    }
}

The problem is that IE7 objects don't have .defineProperty at all, and in IE8, it allegedly only works on host objects (that is, DOM elements and such). If compatibility is an issue, you can't use .defineProperty. (I won't even mention IE6, because it's rather irrelevant anymore outside of China.)

Another issue is that some coding styles like to assume that everyone writes bad code, and prohibit modifying Object.prototype in case someone wants to blindly use for...in. If you care about that, or are using (IMO broken) code that does, try a slightly different version:

function can(obj, methodName)
{
     return ((typeof obj[methodName]) == "function");
}

if (can(someObject, "quack"))
{
    someObject.quack();
}

INSERT INTO atable (x,y,z) VALUES ( NULL,NULL,NULL)

If xCode keep complaining about armv7, make sure you disconnect any connect device (especially iPhone 5!!) and try again. Took me hours to find out that little piece of information.

I came across the same situation, I found the answer with use of socket library helpful but it doesn't provide support for ipv6 addresses. Found a better way for it:

Unfortunately it Works for python3 only

import ipaddress

def valid_ip(address):
    try: 
        print ipaddress.ip_address(address)
        return True
    except:
        return False

print valid_ip('10.10.20.30')
print valid_ip('2001:DB8::1')
print valid_ip('gibberish')

It can and it should be easy as :

class OneHotEncoder:
    def __init__(self,optionKeys):
        length=len(optionKeys)
        self.__dict__={optionKeys[j]:[0 if i!=j else 1 for i in range(length)] for j in range(length)}

Usage :

ohe=OneHotEncoder(["A","B","C","D"])
print(ohe.A)
print(ohe.D)

Another possible way to do this:

In system tray, right click on docker icon, then click on Switch to Linux containers.

$emit

It dispatches an event name upwards through the scope hierarchy and notify to the registered $rootScope.Scope listeners. The event life cycle starts at the scope on which $emit was called. The event traverses upwards toward the root scope and calls all registered listeners along the way. The event will stop propagating if one of the listeners cancels it.

$broadcast

It dispatches an event name downwards to all child scopes (and their children) and notify to the registered $rootScope.Scope listeners. The event life cycle starts at the scope on which $broadcast was called. All listeners for the event on this scope get notified. Afterwards, the event traverses downwards toward the child scopes and calls all registered listeners along the way. The event cannot be canceled.

$on

It listen on events of a given type. It can catch the event dispatched by $broadcast and $emit.

Visual demo:

Demo working code, visually showing scope tree (parent/child relationship):
http://plnkr.co/edit/am6IDw?p=preview

Demonstrates the method calls:

  $scope.$on('eventEmitedName', function(event, data) ...
  $scope.broadcastEvent
  $scope.emitEvent

The API hasn't changed - only the syntax has. You can make a UIButton and add it like this:

var button = UIButton(frame: CGRectMake(0, 0, 50, 50))
self.view.addSubview(button) // assuming you're in a view controller

below will work with any previously pushed revision, not only HEAD

for abbreviated revision hash:

git log -1 --pretty=format:%h

for long revision hash:

git log -1 --pretty=format:%H

Setting the style.zIndex property has no effect on non-positioned elements, that is, the element must be either absolutely positioned, relatively positioned, or fixed.

So I would try:

$(this).parent().css('position', 'relative');
$(this).parent().css('z-index', 3000);

In Kibana 6.5, you can generate CSV under the Share Tab -> CSV Reports.

The request will be queued. Once the CSV is generated, it will be available for download under Management -> Reporting

In case you need further info for your log/audit you can OUTPUT clause: This way, not only you keep the number of rows affected, but also what records.

As an example of the Output Clause during inserts: SQL Server list of insert identities

DECLARE @InsertedIDs table(ID int);

INSERT INTO YourTable
    OUTPUT INSERTED.ID
        INTO @InsertedIDs 
    SELECT ...

HTH

Aight fam, after some research and experimenting, I think the best approach is to have the thing's height at 0px, and let it transition to an exact height. You get the exact height with JavaScript. The JavaScript isn't doing the animating, it's just changing the height value. Check it:

function setInfoHeight() {
  $(window).on('load resize', function() {
    $('.info').each(function () {
      var current = $(this);
      var closed = $(this).height() == 0;
      current.show().height('auto').attr('h', current.height() );
      current.height(closed ? '0' : current.height());
    });
  });

Whenever the page loads or is resized, the element with class info will get its h attribute updated. Then you could have a button trigger the style="height: __" to set it to that previously set h value.

function moreInformation() {
  $('.icon-container').click(function() {
    var info = $(this).closest('.dish-header').next('.info'); // Just the one info
    var icon = $(this).children('.info-btn'); // Select the logo

    // Stop any ongoing animation loops. Without this, you could click button 10
    // times real fast, and watch an animation of the info showing and closing
    // for a few seconds after
    icon.stop();
    info.stop();

    // Flip icon and hide/show info
    icon.toggleClass('flip');

    // Metnod 1, animation handled by JS
    // info.slideToggle('slow');

    // Method 2, animation handled by CSS, use with setInfoheight function
    info.toggleClass('active').height(icon.is('.flip') ? info.attr('h') : '0');

  });
};

Here's the styling for the info class.

.info {
  display: inline-block;
  height: 0px;
  line-height: 1.5em;
  overflow: hidden;
  padding: 0 1em;
  transition: height 0.6s, padding 0.6s;
  &.active {
    border-bottom: $thin-line;
    padding: 1em;
  }
}

I used this on one of my projects so class names are specific. You can change them up however you like.

The styling might not be supported cross-browser. Works fine in chrome.

Below is the live example for this code. Just click on the ? icon to start the animation

CodePen

I'd recommend using the MomentJS libraries. They make all interactions with Dates a lot simpler.

If you use Moment, your code would be as simple as this:

var today = moment();
var nextMonth = today.add('month', 1);
// note that both variables `today` and `nextMonth` refer to 
// the next month at this point, because `add` mutates in-place

You can find MomentJS here: http://momentjs.com/

UPDATE:

In JavaScript, the Date.getDate() function returns the current day of the month from 1-31. You are subtracting 6 from this number, and it is currently the 3rd of the month. This brings the value to -3.

Two ways:

1. Implement ActionListener in your class, then use jBtnSelection.addActionListener(this); Later, you'll have to define a menthod, public void actionPerformed(ActionEvent e). However, doing this for multiple buttons can be confusing, because the actionPerformed method will have to check the source of each event (e.getSource()) to see which button it came from.

2. Use anonymous inner classes:

jBtnSelection.addActionListener(new ActionListener() { 
  public void actionPerformed(ActionEvent e) { 
    selectionButtonPressed();
  } 
} );

Later, you'll have to define selectionButtonPressed(). This works better when you have multiple buttons, because your calls to individual methods for handling the actions are right next to the definition of the button.

The second method also allows you to call the selection method directly. In this case, you could call selectionButtonPressed() if some other action happens, too - like, when a timer goes off or something (but in this case, your method would be named something different, maybe selectionChanged()).

Select 
    p.Name,
    p.SS,
    f.fear
From
    Persons p
left join
        Person_Fear pf
    inner join
        Fears f
    on
        pf.fearID = f.fearID
 on
    p.personID = pf.PersonID

Combining Saurabh Chandra Patel's answer with Molecular Man's observation, you should have something like this:

JSON.parse('{"TeamList" : [{"teamid" : "1","teamname" : "Barcelona"}]}');

try putting a delay on the last color fade.

$("p#44.test").delay(3000).css("background-color","red");

What are valid values for the id attribute in HTML?
ID's cannot start with digits!!!

public function store()
{
    $this->validate(request(), [
        'title' => 'required',
        'slug' => 'required',
        'file' => 'required|image|mimes:jpg,jpeg,png,gif'
    ]);

    $fileName = null;
    if (request()->hasFile('file')) {
        $file = request()->file('file');
        $fileName = md5($file->getClientOriginalName() . time()) . "." . $file->getClientOriginalExtension();
        $file->move('./uploads/categories/', $fileName);    
    }

    Category::create([
        'title' => request()->get('title'),
        'slug' => str_slug(request()->get('slug')),
        'description' => request()->get('description'),
        'category_img' => $fileName,
        'category_status' => 'DEACTIVE'
    ]);

    return redirect()->to('/admin/category');
}

Here I found some simplest solution to sort the python dict by key using pprint. eg.

>>> x = {'a': 10, 'cd': 20, 'b': 30, 'az': 99} 
>>> print x
{'a': 10, 'b': 30, 'az': 99, 'cd': 20}

but while using pprint it will return sorted dict

>>> import pprint 
>>> pprint.pprint(x)
{'a': 10, 'az': 99, 'b': 30, 'cd': 20}

Assuming that the items in your CheckedListBox are strings:

  for (int i = 0; i < checkedListBox1.Items.Count; i++)
  {
    if ((string)checkedListBox1.Items[i] == value)
    {
      checkedListBox1.SetItemChecked(i, true);
    }
  }

Or

  int index = checkedListBox1.Items.IndexOf(value);

  if (index >= 0)
  {
    checkedListBox1.SetItemChecked(index, true);
  }

I think that the second part of the question:

Also, what are bitwise operators actually used for? I'd appreciate some examples.

Has been only partially addressed. These are my two cents on that matter.

Bitwise operations in programming languages play a fundamental role when dealing with a lot of applications. Almost all low-level computing must be done using this kind of operations.

In all applications that need to send data between two nodes, such as:

• computer networks;

• telecommunication applications (cellular phones, satellite communications, etc).

In the lower level layer of communication, the data is usually sent in what is called frames. Frames are just strings of bytes that are sent through a physical channel. This frames usually contain the actual data plus some other fields (coded in bytes) that are part of what is called the header. The header usually contains bytes that encode some information related to the status of the communication (e.g, with flags (bits)), frame counters, correction and error detection codes, etc. To get the transmitted data in a frame, and to build the frames to send data, you will need for sure bitwise operations.

In general, when dealing with that kind of applications, an API is available so you don't have to deal with all those details. For example, all modern programming languages provide libraries for socket connections, so you don't actually need to build the TCP/IP communication frames. But think about the good people that programmed those APIs for you, they had to deal with frame construction for sure; using all kinds of bitwise operations to go back and forth from the low-level to the higher-level communication.

As a concrete example, imagine some one gives you a file that contains raw data that was captured directly by telecommunication hardware. In this case, in order to find the frames, you will need to read the raw bytes in the file and try to find some kind of synchronization words, by scanning the data bit by bit. After identifying the synchronization words, you will need to get the actual frames, and SHIFT them if necessary (and that is just the start of the story) to get the actual data that is being transmitted.

Another very different low level family of application is when you need to control hardware using some (kind of ancient) ports, such as parallel and serial ports. This ports are controlled by setting some bytes, and each bit of that bytes has a specific meaning, in terms of instructions, for that port (see for instance http://en.wikipedia.org/wiki/Parallel_port). If you want to build software that does something with that hardware you will need bitwise operations to translate the instructions you want to execute to the bytes that the port understand.

For example, if you have some physical buttons connected to the parallel port to control some other device, this is a line of code that you can find in the soft application:

read = ((read ^ 0x80) >> 4) & 0x0f; 

Hope this contributes.

Yes, SQL Server 2012 supports multiple inserts - that feature was introduced in SQL Server 2008.

That makes me wonder if you have Management Studio 2012, but you're really connected to a SQL Server 2005 instance ...

What version of the SQL Server engine do you get from SELECT @@VERSION ??

You can flatten the list and then store the values to a CommaSeparatedIntegerField. When you read back from the database, just group the values back into threes.

Disclaimer: according to database normalization theory, it is better not to store collections in single fields; instead you would be encouraged to store the values in those triplets in their own fields and link them via foreign keys. In the real world, though, sometimes that is too cumbersome/slow.

Normally, that is not an error per se; it is a warning that the first file it found that matches the -lPI-Http argument to the compiler/linker is not valid. The error occurs when no other library can be found with the right content.

So, you need to look to see whether /dvlpmnt/libPI-Http.a is a library of 32-bit object files or of 64-bit object files - it will likely be 64-bit if you are compiling with the -m32 option. Then you need to establish whether there is an alternative libPI-Http.a or libPI-Http.so file somewhere else that is 32-bit. If so, ensure that the directory that contains it is listed in a -L/some/where argument to the linker. If not, then you will need to obtain or build a 32-bit version of the library from somewhere.

To establish what is in that library, you may need to do:

mkdir junk
cd junk
ar x /dvlpmnt/libPI-Http.a
file *.o
cd ..
rm -fr junk

The 'file' step tells you what type of object files are in the archive. The rest just makes sure you don't make a mess that can't be easily cleaned up.

Hercules is fantastic. It's a fully functioning tcp/udp client/server, amazing for debugging sockets. More details on the web site.

You can do this with css transforms, though be careful with container height/width. Also you may need to position it lower:

input[type="range"] {_x000D_
   position: absolute;_x000D_
   top: 40%;_x000D_
   transform: rotate(270deg);_x000D_
}

<input type="range"/>

or the 3d transform equivalent:

input[type="range"] {
   transform: rotateZ(270deg);
}

You can also use this to switch the direction of the slide by setting it to 180deg or 90deg for horizontal or vertical respectively.

It's \n. When you're reading or writing text mode files, or to stdin/stdout etc, you must use \n, and C will handle the translation for you. When you're dealing with binary files, by definition you are on your own.

onBlur="javascript:{this.value = this.value.toUpperCase(); }

will change uppercase easily.

If, as I just encountered, you happen to have a jar file listed in the Project Structures->Libraries that is not in your classpath, the correct answer can be found by following the link given by @CrazyCoder above: Look here http://www.jetbrains.com/idea/webhelp/configuring-module-dependencies-and-libraries.html

This says that to add the jar file as a module dependency within the Project Structure dialog:

1. Open Project Structure
2. Select Modules, then click on the module for which you want the dependency
3. Choose the Dependencies tab
4. Click the '+' at the bottom of the page and choose the appropriate way to connect to the library file. If the jar file is already listed in Libraries, then select 'Library'.

You could write a convenience method:

public PrintStream print(String format, Object... arguments) {
    return System.out.format(format, arguments);
}

But as you can see, you've simply just renamed format (or printf).

Here's how you could use it:

private void printScores(Player... players) {
    for (int i = 0; i < players.length; ++i) {
        Player player = players[i];
        String name   = player.getName();
        int    score  = player.getScore();
        // Print name and score followed by a newline
        System.out.format("%s: %d%n", name, score);
    }
}

// Print a single player, 3 players, and all players
printScores(player1);
System.out.println();
printScores(player2, player3, player4);
System.out.println();
printScores(playersArray);

// Output
Abe: 11

Bob: 22
Cal: 33
Dan: 44

Abe: 11
Bob: 22
Cal: 33
Dan: 44

Note there's also the similar System.out.printf method that behaves the same way, but if you peek at the implementation, printf just calls format, so you might as well use format directly.

• Varargs
• PrintStream#format(String format, Object... args)
• PrintStream#printf(String format, Object... args)

one more, after you create user by following cmd-1, please assign read/write/root role to the user by cmd-2. then restart mongodb by cmd "mongod --auth".

The benefit of assign role to the user is you can do read/write operation by mongo shell or python/java and so on, otherwise you will meet "pymongo.errors.OperationFailure: not authorized" when you try to read/write your db.

cmd-1:

use admin
db.createUser({
  user: "newUsername",
  pwd: "password",
  roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
})

cmd-2:

db.grantRolesToUser('newUsername',[{ role: "root", db: "admin" }])

Swift 4.2 Solution: For transparent Background:

1. For General Approach:

   override func viewDidLoad() {
       super.viewDidLoad()
   
       self.navigationController?.navigationBar.setBackgroundImage(UIImage(), for: UIBarMetrics.default)
       self.navigationController?.navigationBar.shadowImage = UIImage()
       self.navigationController?.navigationBar.isTranslucent = true
   
   }
   

2. For Specific Object:

   override func viewDidLoad() {
       super.viewDidLoad()
   
       navBar.setBackgroundImage(UIImage(), for: UIBarMetrics.default)
       navBar.shadowImage = UIImage()
       navBar.navigationBar.isTranslucent = true
   
   }
   

Hope it's useful.

Yet another reason may be that your entity class has several properties named somhow /.*id/i - so ending with ID case insensitive AND elementary type AND there is no [Key] attribute.

EF will namely try to figure out the PK by itself by looking for elementary typed properties ending in ID.

See my case:

public class MyTest, IMustHaveTenant
{
  public long Id { get; set; }
  public int TenantId { get; set; }
  [MaxLength(32)]
  public virtual string Signum{ get; set; }
  public virtual string ID { get; set; }
  public virtual string ID_Other { get; set; }
}

don't ask - lecacy code. The Id was even inherited, so I could not use [Key] (just simplifying the code here)

But here EF is totally confused.

What helped was using modelbuilder this in DBContext class.

            modelBuilder.Entity<MyTest>(f =>
            {
                f.HasKey(e => e.Id);
                f.HasIndex(e => new { e.TenantId });
                f.HasIndex(e => new { e.TenantId, e.ID_Other });
            });

the index on PK is implicit.

If the request if GET and we passed some query parameters then,

fro`enter code here`m flask import request
@app.route('/')
@app.route('/data')
def data():
   if request.method == 'GET':
      # Get the parameters by key
      arg1 = request.args.get('arg1')
      arg2 = request.args.get('arg2')
      # Generate the query string
      query_string="?arg1={0}&arg2={1}".format(arg1, arg2)
      return render_template("data.html", query_string=query_string)

I finally figured out a how to use Maven. From within Eclipse, create a new Maven project.

Download Maven, extract the archive, add the /bin folder to path.

Validate install from command-line by running mvn -v (will print version and java install path)

Change to the project root folder (where pom.xml is located) and run:

mvn dependency:copy-dependencies

All jar-files are downloaded to /target/dependency.

To set another output directory:

mvn dependency:copy-dependencies -DoutputDirectory="c:\temp"

Now it's possible to re-use this Maven-project for all dependency downloads by altering the pom.xml

Add jars to java project by build path -> configure build path -> libraries -> add JARs..

create a new java project in Eclipse and copy .java files to its src directory, if you don't know where those source files should be placed, right click on the root of the project and choose new->class to create a test class and see where its .java file is placed, then put other files with it, in the same directory, you may have to adjust the package in those source files according to the new project directory structure.

if you use external libraries in your code, you have two options: either copy / download jar files or use maven if you use maven you'll have to create the project at maven project in the first place, creating java projects as maven projects are the way to go anyway but that's for another post...

Can I see your User class? This is just using restrictions below. I don't see why Restrictions would be really any different than Examples (I think null fields get ignored by default in examples though).

getCurrentSession().createCriteria(User.class)
.setProjection( Projections.distinct( Projections.projectionList()
.add( Projections.property("name"), "name")
.add( Projections.property("city"), "city")))
.add( Restrictions.eq("city", "TEST")))
.setResultTransformer(Transformers.aliasToBean(User.class))
.list();

I've never used the alaistToBean, but I just read about it. You could also just loop over the results..

List<Object> rows = criteria.list();
for(Object r: rows){
  Object[] row = (Object[]) r;
  Type t = ((<Type>) row[0]);
}

If you have to you can manually populate User yourself that way.

Its sort of hard to look into the issue without some more information to diagnose the issue.

The -i option streams the edited content into a new file and then renames it behind the scenes, anyway.

Example:

sed -i 's/STRING_TO_REPLACE/STRING_TO_REPLACE_IT/g' filename

and

sed -i '' 's/STRING_TO_REPLACE/STRING_TO_REPLACE_IT/g' filename

on macOS.

I think this should do the trick:

<table border="1px" align="center">

According to http://w3schools.com/tags/tag_table.asp this is deprecated, but try it. If it does not work, go for styles, as mentioned on the site.

• Windows: C++, kernel is in C
• Mac: Objective C, kernel is in C (IO PnP subsystem is Embedded C++)
• Linux: Most things are in C, many userland apps are in Python, KDE is all C++

All kernels will use some assembly code as well.

Just as @Saravana mentioned:

flatmap is better but there are other ways to achieve the same

 listStream.reduce(new ArrayList<>(), (l1, l2) -> {
        l1.addAll(l2);
        return l1;
 });

To sum up, there are several ways to achieve the same as follows:

private <T> List<T> mergeOne(Stream<List<T>> listStream) {
    return listStream.flatMap(List::stream).collect(toList());
}

private <T> List<T> mergeTwo(Stream<List<T>> listStream) {
    List<T> result = new ArrayList<>();
    listStream.forEach(result::addAll);
    return result;
}

private <T> List<T> mergeThree(Stream<List<T>> listStream) {
    return listStream.reduce(new ArrayList<>(), (l1, l2) -> {
        l1.addAll(l2);
        return l1;
    });
}

private <T> List<T> mergeFour(Stream<List<T>> listStream) {
    return listStream.reduce((l1, l2) -> {
        List<T> l = new ArrayList<>(l1);
        l.addAll(l2);
        return l;
    }).orElse(new ArrayList<>());
}

private <T> List<T> mergeFive(Stream<List<T>> listStream) {
    return listStream.collect(ArrayList::new, List::addAll, List::addAll);
}

$address = str_replace(" ", "+", $address);

$json = file_get_contents("http://maps.google.com/maps/api/geocode/json?address=$address&sensor=false&region=$region");
$json = json_decode($json);

$lat = $json->{'results'}[0]->{'geometry'}->{'location'}->{'lat'};
$long = $json->{'results'}[0]->{'geometry'}->{'location'}->{'lng'};

Try this:

ls -l  | awk -F : '{sum+=$5} END {print "AVG=",sum/NR}'

NR is an AWK builtin variable to count the no. of records

I also had to come up with an alternate solution, as none of the options listed here worked in my case. I was using an IEnumerable and the underlying data was a IEnumerable and the properties couldn't be enumerated. This did the trick:

// remove "this" if not on C# 3.0 / .NET 3.5
public static DataTable ConvertToDataTable<T>(this IEnumerable<T> data)
{
    List<IDataRecord> list = data.Cast<IDataRecord>().ToList();

    PropertyDescriptorCollection props = null;
    DataTable table = new DataTable();
    if (list != null && list.Count > 0)
    {
        props = TypeDescriptor.GetProperties(list[0]);
        for (int i = 0; i < props.Count; i++)
        {
            PropertyDescriptor prop = props[i];
            table.Columns.Add(prop.Name, Nullable.GetUnderlyingType(prop.PropertyType) ?? prop.PropertyType);
        }
    }
    if (props != null)
    {
        object[] values = new object[props.Count];
        foreach (T item in data)
        {
            for (int i = 0; i < values.Length; i++)
            {
                values[i] = props[i].GetValue(item) ?? DBNull.Value;
            }
            table.Rows.Add(values);
        }
    }
    return table;
}

Maybe not as elegant but another possibility would be to write a formula to do the check and fill it in an adjacent column. You could then filter on that column.

The following looks in cell b14 and would return true for all the file types you mention. This assumes that the file extension is by itself in the column. If it's not it would be a little more complicated but you could still do it this way.

=OR(B14=".pdf",B14=".doc",B14=".docx",B14=".xls",B14=".xlsx",B14=".rtf",B14=".txt",B14=".csv",B14=".pps")

Like I said, not as elegant as the advanced filters but options are always good.

import java.util.LinkedList;
import java.util.Queue;

class MyStack {
    Queue<Integer> queue1 = new LinkedList<Integer>();
    Queue<Integer> queue2 = new LinkedList<Integer>();

    // Push element x onto stack.
    public void push(int x) {
        if(isEmpty()){
            queue1.offer(x);
        }else{
            if(queue1.size()>0){
                queue2.offer(x);
                int size = queue1.size();
                while(size>0){
                    queue2.offer(queue1.poll());
                    size--;
                }
            }else if(queue2.size()>0){
                queue1.offer(x);
                int size = queue2.size();
                while(size>0){
                    queue1.offer(queue2.poll());
                    size--;
                }
            }
        }
    }

    // Removes the element on top of the stack.
    public void pop() {
        if(queue1.size()>0){
            queue1.poll();
        }else if(queue2.size()>0){
            queue2.poll();
        }
    }

    // Get the top element. You can make it more perfect just example
    public int top() {
       if(queue1.size()>0){
            return queue1.peek();
        }else if(queue2.size()>0){
            return queue2.peek();
        }
        return 0;
    }

    // Return whether the stack is empty.
    public boolean isEmpty() {
        return queue1.isEmpty() && queue2.isEmpty();
    }
}

Make sure it is

public static void main(String[] argv)

No other signature will do.

There is no syntax for block quote in VBA. The work around is to use the button to quickly block or unblock multiple lines of code.

None of the solutions above worked for me.

The solution that finally worked for me was switching SSH client. GIT_SSH environment variable was set to the OpenSSH provided by Windows Server 2019. Version 7.7.2.1

C:\Windows\System32\OpenSSH\ssh.exe

I simply installed putty, 0.72

choco install putty

And changed GIT_SSH to

C:\ProgramData\chocolatey\lib\putty.portable\tools\PLINK.EXE

Based on above solutions, here comes a extension class which you can use to serialize and deserialize any object. Any other XML attributions are up to you.

Just use it like this:

        string s = new MyObject().Serialize(); // to serialize into a string
        MyObject b = s.Deserialize<MyObject>();// deserialize from a string



internal static class Extensions
{
    public static T Deserialize<T>(this string value)
    {
        var xmlSerializer = new XmlSerializer(typeof(T));

        return (T)xmlSerializer.Deserialize(new StringReader(value));
    }

    public static string Serialize<T>(this T value)
    {
        if (value == null)
            return string.Empty;

        var xmlSerializer = new XmlSerializer(typeof(T));

        using (var stringWriter = new StringWriter())
        {
            using (var xmlWriter = XmlWriter.Create(stringWriter, new XmlWriterSettings { Indent = true }))
            {
                xmlSerializer.Serialize(xmlWriter, value);
                return stringWriter.ToString();
            }
        }
    }
}

Go to DDMS->Devices->Click on View Menu Down arrow on right side -> select "reset adb" option it will work

In Android Studio: open the Android Device Monitor (Tools->Android) and click on the arrow on the 'Devices' tab to reset the adb

Too late, but after reading all helpful answers and comments, I ended up using Microsoft.Extensions.Configuration.Binder extension package and play a little around to get rid of hardcoded configuration keys.

My solution:

IConfigSection.cs

public interface IConfigSection
{
}

ConfigurationExtensions.cs

public static class ConfigurationExtensions
{
    public static TConfigSection GetConfigSection<TConfigSection>(this IConfiguration configuration) where TConfigSection : IConfigSection, new()
    {
        var instance = new TConfigSection();
        var typeName = typeof(TConfigSection).Name;
        configuration.GetSection(typeName).Bind(instance);

        return instance;
    }
}

appsettings.json

{
   "AppConfigSection": {
      "IsLocal": true
   },
   "ConnectionStringsConfigSection": {
      "ServerConnectionString":"Server=.;Database=MyDb;Trusted_Connection=True;",
      "LocalConnectionString":"Data Source=MyDb.db",
   },
}

To access a strongly typed config, you just need to create a class for that, which implements IConfigSection interface(Note: class names and field names should exactly match section in appsettings.json)

AppConfigSection.cs

public class AppConfigSection: IConfigSection
{
    public bool IsLocal { get; set; }
}

ConnectionStringsConfigSection.cs

public class ConnectionStringsConfigSection : IConfigSection
{
    public string ServerConnectionString { get; set; }
    public string LocalConnectionString { get; set; }

    public ConnectionStringsConfigSection()
    {
        // set default values to avoid null reference if
        // section is not present in appsettings.json
        ServerConnectionString = string.Empty;
        LocalConnectionString = string.Empty;
    }
}

And finally, a usage example:

Startup.cs

public class Startup
{
    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;
    }

    public IConfiguration Configuration { get; }

    public void ConfigureServices(IServiceCollection services)
    {
        // some stuff

        var app = Configuration.GetConfigSection<AppConfigSection>();
        var connectionStrings = Configuration.GetConfigSection<ConnectionStringsConfigSection>();

        services.AddDbContext<AppDbContext>(options =>
        {
            if (app.IsLocal)
            {
                options.UseSqlite(connectionStrings.LocalConnectionString);
            }
            else
            {
                options.UseSqlServer(connectionStrings.ServerConnectionString);
            }
        });

        // other stuff
    }
}

To make it neat, you can move above code into an extension method.

That's it, no hardcoded configuration keys.

Declaring an enum variable is done like this:

enum strategy {RANDOM, IMMEDIATE, SEARCH};
enum strategy my_strategy = IMMEDIATE;

However, you can use a typedef to shorten the variable declarations, like so:

typedef enum {RANDOM, IMMEDIATE, SEARCH} strategy;
strategy my_strategy = IMMEDIATE;

Having a naming convention to distinguish between types and variables is a good idea:

typedef enum {RANDOM, IMMEDIATE, SEARCH} strategy_type;
strategy_type my_strategy = IMMEDIATE;

Well you can not run code from notepad so that means you are opening up the page from the file system. aka c:/foo/bar/hello.html

When you run the code from the asp.net page, you are running it from localhost. aka http://loalhost:1234/assdf.html

Each of these run in different security zones on IE.

The following should be clean (using find_package) and work (the find module is called FindThreads):

cmake_minimum_required (VERSION 2.6) 
find_package (Threads)
add_executable (myapp main.cpp ...)
target_link_libraries (myapp ${CMAKE_THREAD_LIBS_INIT})

I'm implementing it in Play Framework and for me it worked like this:

1) Notice that I used data-rule-equalTo in input tag for the id inputPassword1. The code section of userform in my Modal:

<div class="form-group">
    <label for="pass1">@Messages("authentication.password")</label>
    <input class="form-control required" id="inputPassword1" placeholder="@Messages("authentication.password")" type="password" name="password" maxlength=10 minlength=5>
</div>
<div class="form-group">
    <label for="pass2">@Messages("authentication.password2")</label>
    <input class="form-control required" data-rule-equalTo="#inputPassword1" id="inputPassword2" placeholder="@Messages("authentication.password")" type="password" name="password2">
</div>

2)Since I used validator within a Modal

$(document).on("click", ".createUserModal", function () {
       $(this).find('#userform').validate({
           rules: {
               firstName: "required",
               lastName: "required",
               nationalId: {
                   required: true,
                   digits:true
               },
               email: {
                   required: true,
                   email: true
               },
               optradio: "required",
               password :{
                   required: true,
                   minlength: 5
               },
               password2: {
                   required: true
               }
           },
           highlight: function (element) {
               $(element).parent().addClass('error')
           },
           unhighlight: function (element) {
               $(element).parent().removeClass('error')
           },
           onsubmit: true
       });

   });

Hope it helps someone :).

There's no need for you to use super-call of the ActionBarDrawerToggle which requires the Toolbar. This means instead of using the following constructor:

ActionBarDrawerToggle(Activity activity, DrawerLayout drawerLayout, Toolbar toolbar, int openDrawerContentDescRes, int closeDrawerContentDescRes)

You should use this one:

ActionBarDrawerToggle(Activity activity, DrawerLayout drawerLayout, int openDrawerContentDescRes, int closeDrawerContentDescRes)

So basically the only thing you have to do is to remove your custom drawable:

super(mActivity, mDrawerLayout, R.string.ns_menu_open, R.string.ns_menu_close);

More about the "new" ActionBarDrawerToggle in the Docs (click).

INSERT INTO #TempTable
EXEC(@SelectStatement)

No need to use a macro. Supposing your first string is in A1.

=RIGHT(A1, 4)

Drag this down and you will get your four last characters.

Edit: To be sure, if you ever have sequences like 'ABC DEF' and want the last four LETTERS and not CHARACTERS you might want to use trimspaces()

=RIGHT(TRIMSPACES(A1), 4)

Edit: As per brettdj's suggestion, you may want to check that your string is actually 4-character long or more:

=IF(TRIMSPACES(A1)>=4, RIGHT(TRIMSPACES(A1), 4), TRIMSPACES(A1))

Try the below logic to find out the median:

Consider a table with the below numbers: 1,1,2,3,4,5

THE MEDIAN is 2.5

with tempa as ( select num,count(num) over() as Cnt, row_number() over (order by num) as Rnum from temp), tempb as ( select round(cnt/2) as ref_value from tempa where mod(cnt,2)<>0 union all select round(cnt/2) from tempa where mod(cnt,2)=0 union all select round(cnt/2+1) from tempa where mod(cnt,2)=0 ) select avg(num) from tempa where rnum in (select * from tempb);

class Class1(object):
    pass

class Class2(Class1):
    pass

Class2 is a sub-class of Class1

Delete the .refresh.dll file if you are under source control. Then rebuild. It should work. This worked for me

Testing nullity (if (value == null)) or non-nullity (if (value != null)) is less verbose than testing the definition status of a variable.

Moreover, testing if (value) (or if( obj.property)) to ensure the existence of your variable (or object property) fails if it is defined with a boolean false value. Caveat emptor :)

If you're using .NET 4, simply use File.ReadLines which does it all for you. I suspect it's much the same as yours, except it may also use FileOptions.SequentialScan and a larger buffer (128 seems very small).

Identity of entities is defined by their primary keys. Since firstname and lastname are not parts of the primary key, you cannot tell JPA to treat Users with the same firstnames and lastnames as equal if they have different userIds.

So, if you want to update a User identified by its firstname and lastname, you need to find that User by a query, and then change appropriate fields of the object your found. These changes will be flushed to the database automatically at the end of transaction, so that you don't need to do anything to save these changes explicitly.

EDIT:

Perhaps I should elaborate on overall semantics of JPA. There are two main approaches to design of persistence APIs:

• insert/update approach. When you need to modify the database you should call methods of persistence API explicitly: you call insert to insert an object, or update to save new state of the object to the database.

• Unit of Work approach. In this case you have a set of objects managed by persistence library. All changes you make to these objects will be flushed to the database automatically at the end of Unit of Work (i.e. at the end of the current transaction in typical case). When you need to insert new record to the database, you make the corresponding object managed. Managed objects are identified by their primary keys, so that if you make an object with predefined primary key managed, it will be associated with the database record of the same id, and state of this object will be propagated to that record automatically.

JPA follows the latter approach. save() in Spring Data JPA is backed by merge() in plain JPA, therefore it makes your entity managed as described above. It means that calling save() on an object with predefined id will update the corresponding database record rather than insert a new one, and also explains why save() is not called create().

This one will calculate a HashCode for each object, optimized for string, number and virtually anything that has a getHashCode function. For the rest it assigns a new reference number.

(function() {
  var __gRefID = 0;
  window.getHashCode = function(ref)
  {
      if (ref == null) { throw Error("Unable to calculate HashCode on a null reference"); }

      // already cached reference id
      if (ref.hasOwnProperty("__refID")) { return ref["__refID"]; }

      // numbers are already hashcodes
      if (typeof ref === "number") { return ref; }

      // strings are immutable, so we need to calculate this every time
      if (typeof ref === "string")
      {
          var hash = 0, i, chr;
          for (i = 0; i < ref.length; i++) {
            chr = ref.charCodeAt(i);
            hash = ((hash << 5) - hash) + chr;
            hash |= 0;
          }
          return hash;
      }

      // virtual call
      if (typeof ref.getHashCode === "function") { return ref.getHashCode(); }

      // generate and return a new reference id
      return (ref["__refID"] = "ref" + __gRefID++);
  }
})();

Add this code in css:

 select, input[type="text"]{
      width:100%;
      box-sizing:border-box;
    }

Perhaps use plt.annotate:

import numpy as np
import matplotlib.pyplot as plt

N = 10
data = np.random.random((N, 4))
labels = ['point{0}'.format(i) for i in range(N)]

plt.subplots_adjust(bottom = 0.1)
plt.scatter(
    data[:, 0], data[:, 1], marker='o', c=data[:, 2], s=data[:, 3] * 1500,
    cmap=plt.get_cmap('Spectral'))

for label, x, y in zip(labels, data[:, 0], data[:, 1]):
    plt.annotate(
        label,
        xy=(x, y), xytext=(-20, 20),
        textcoords='offset points', ha='right', va='bottom',
        bbox=dict(boxstyle='round,pad=0.5', fc='yellow', alpha=0.5),
        arrowprops=dict(arrowstyle = '->', connectionstyle='arc3,rad=0'))

plt.show()

You can user pagination of Instagram PHP API: https://github.com/cosenary/Instagram-PHP-API/wiki/Using-Pagination

Something like that:

    $Instagram = new MetzWeb\Instagram\Instagram(array(
        "apiKey"      => IG_APP_KEY,
        "apiSecret"   => IG_APP_SECRET,
        "apiCallback" => IG_APP_CALLBACK
    ));
    $Instagram->setSignedHeader(true);

    $pictures = $Instagram->getUserMedia(123);
    do {

        foreach ($pictures->data as $picture_data):

            echo '<img src="'.$picture_data->images->low_resolution->url.'">';

        endforeach;

    } while ($pictures = $instagram->pagination($pictures));

I'm not sure of all the details, but my understanding is that OLE DB and ODBC are two APIs that are available for connecting to various types of databases without having to deal with all the implementation specific details of each. According to the Wikipedia article on OLE DB, OLE DB is Microsoft's successor to ODBC, and provides some features that you might not be able to do with ODBC such as accessing spreadsheets as database sources.

The elements of a sequence need to be indented at the same level. Assuming you want two jobs (A and B) each with an ordered list of key value pairs, you should use:

jobs:
 - - name: A
   - schedule: "0 0/5 * 1/1 * ? *"
   - - type: mongodb.cluster
     - config:
       - host: mongodb://localhost:27017/admin?replicaSet=rs
       - minSecondaries: 2
       - minOplogHours: 100
       - maxSecondaryDelay: 120
 - - name: B
   - schedule: "0 0/5 * 1/1 * ? *"
   - - type: mongodb.cluster
     - config:
       - host: mongodb://localhost:27017/admin?replicaSet=rs
       - minSecondaries: 2
       - minOplogHours: 100
       - maxSecondaryDelay: 120

Converting the sequences of (single entry) mappings to a mapping as @Tsyvarrev does is also possible, but makes you lose the ordering.

event.preventDefault()

Doesn't work in all browsers. Instead you could return false in OnClick event.

onClick="toggle_it('tr1');toggle_it('tr2'); return false;">

Not sure if this is the best way, but I tested in IE, FF and Chrome and its working fine.

I had this happen in Visual Studio 2015 too for an interesting reason. Just adding it here in case it happens to someone else.

I already had number of files in project and I was adding another one that would have main function in it, however when I initially added the file I made a typo in the extension (.coo instead of .cpp). I corrected that but when I was done I got this error. It turned out that Visual Studio was being smart and when file was added it decided that it is not a source file due to the initial extension.

Right-clicking on file in solution explorer and selecting Properties -> General -> ItemType and setting it to "C/C++ compiler" fixed the issue.

If you get this error in PowerShell, it's most likely because you're using Resolve-Path to resolve a remote path, e.g.

 Resolve-Path \\server\share\path

In this case, Resolve-Path returns an object that, when converted to a string, doesn't return a valid path. It returns PowerShell's internal path:

> [string](Resolve-Path \\server\share\path)
Microsoft.PowerShell.Core\FileSystem::\\server\share\path

The solution is to use the ProviderPath property on the object returned by Resolve-Path:

> Resolve-Path \\server\share\path | Select-Object -ExpandProperty PRoviderPath
\\server\share\path
> (Resolve-Path \\server\share\path).ProviderPath
\\server\share\path

May be useful for someone.. In Run as if you are getting only java application (No spring bootapp).. then probably you need to install "Spring Tools (aka Spring IDE and Spring Tool Suite)" through Eclipse market place. After successful installation and restart of Eclipse.. now you can see in Run as "Spring Boot app".

Use keypress event on usersSearch textbox and look for Enter button. If enter button is pressed then trigger the search button click event which will do the rest of work. Try this.

$('document').ready(function(){
    $('#searchButton').click(function(){
        var search = $('#usersSearch').val();
        $.post('../searchusers.php',{search: search},function(response){
            $('#userSearchResultsTable').html(response);
        });
    })
    $('#usersSearch').keypress(function(e){
        if(e.which == 13){//Enter key pressed
            $('#searchButton').click();//Trigger search button click event
        }
    });

});

Demo

#include<algorithm>
#include<vector>
#include<iostream>
using namespace std;
int main()
{
    vector<int>v1;
    for(int i=0; i<5; i++)
        v1.push_back(i*2);
    for(int i=0; i<v1.size(); i++)
        cout<<v1[i];    //02468
    reverse(v1.begin(),v1.end());
    
    for(int i=0; i<v1.size(); i++)
        cout<<v1[i];   //86420
}

Say util.R produces a function foo(). You can check if this function is available in the global environment and source the script if it isn't:

if(identical(length(ls(pattern = "^foo$")), 0))
    source("util.R")

That will find anything with the name foo. If you want to find a function, then (as mentioned by @Andrie) exists() is helpful but needs to be told exactly what type of object to look for, e.g.

if(exists("foo", mode = "function"))
    source("util.R")

Here is exists() in action:

> exists("foo", mode = "function")
[1] FALSE
> foo <- function(x) x
> exists("foo", mode = "function")
[1] TRUE
> rm(foo)
> foo <- 1:10
> exists("foo", mode = "function")
[1] FALSE

All above answers perfectly gives the solution to center the form using Bootstrap 4. However, if someone wants to use out of the box Bootstrap 4 css classes without help of any additional styles and also not wanting to use flex, we can do like this.

A sample form

HTML

<div class="container-fluid h-100 bg-light text-dark">
  <div class="row justify-content-center align-items-center">
    <h1>Form</h1>    
  </div>
  <hr/>
  <div class="row justify-content-center align-items-center h-100">
    <div class="col col-sm-6 col-md-6 col-lg-4 col-xl-3">
      <form action="">
        <div class="form-group">
          <select class="form-control">
                    <option>Option 1</option>
                    <option>Option 2</option>
                  </select>
        </div>
        <div class="form-group">
          <input type="text" class="form-control" />
        </div>
        <div class="form-group text-center">
          <div class="form-check-inline">
            <label class="form-check-label">
    <input type="radio" class="form-check-input" name="optradio">Option 1
  </label>
          </div>
          <div class="form-check-inline">
            <label class="form-check-label">
    <input type="radio" class="form-check-input" name="optradio">Option 2
  </label>
          </div>
          <div class="form-check-inline">
            <label class="form-check-label">
    <input type="radio" class="form-check-input" name="optradio" disabled>Option 3
  </label>
          </div>
        </div>
        <div class="form-group">
          <div class="container">
            <div class="row">
              <div class="col"><button class="col-6 btn btn-secondary btn-sm float-left">Reset</button></div>
              <div class="col"><button class="col-6 btn btn-primary btn-sm float-right">Submit</button></div>
            </div>
          </div>
        </div>

      </form>
    </div>
  </div>
</div>

I hope this helps someone. Thank you.

That's because you created a Web Site instead of a Web Application. The cs/vb files can only be seen in a Web Application, but in a website you can't have a separate cs/vb file.

Edit: In the website you can add a cs file behavior like..

<%@ Application CodeFile="Global.asax.cs" Inherits="ApplicationName.MyApplication" Language="C#" %>

~/Global.asax.cs:

namespace ApplicationName
{
    public partial class MyApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
        }
    }
}

curl's --data will by default send Content-Type: application/x-www-form-urlencoded in the request header. However, when using Postman's raw body mode, Postman sends Content-Type: text/plain in the request header.

So to achieve the same thing as Postman, specify -H "Content-Type: text/plain" for curl:

curl -X POST -H "Content-Type: text/plain" --data "this is raw data" http://78.41.xx.xx:7778/

Note that if you want to watch the full request sent by Postman, you can enable debugging for packed app. Check this link for all instructions. Then you can inspect the app (right-click in Postman) and view all requests sent from Postman in the network tab :

Just do it like this:

if(!document.getElementById("someId") { /Some code. Note the NOT (!) in the expresion/ };

If element with id "someId" does not exist expresion will return TRUE (NOT FALSE === TRUE) or !false === true;

try this code:

<!DOCTYPE html>
<html>
    <head>
        <meta charset="UTF-8">
        <meta name="format-detection" content="telephone-no">
        <meta name="viewport" content="user-scalable=no, initial-scale=1, minimum-scale=1, maximum-scale=1, width=device-width, height=device-height, target-densitydpi=device-dpi">
        <title>Test</title>
    </head>
    <body>
      <script>
var createPerson = function (name) {
    var person;
    if (!document.getElementById(name)) {
        alert("Element does not exist. Let's create it.");
      person = document.createElement("div");
//add argument name as the ID of the element
      person.id = name;
//append element to the body of the document
      document.body.appendChild(person);
    } else {
        alert("Element exists. Lets get it by ID!");
      person = document.getElementById(name);
    }
    person.innerHTML = "HI THERE!";

};
//run the function.
createPerson("someid");
          </script>
       </body>
</html>

Try this in your browser and it should alert "Element does not exist. Let's create it."

Now add

<div id="someid"></div>

to the body of the page and try again. Voila! :)

Pandas 0.24.0+ solution

In Pandas 0.24.0 a new feature was introduced specifically designed for fast writes to Postgres. You can learn more about it here: https://pandas.pydata.org/pandas-docs/stable/user_guide/io.html#io-sql-method

import csv
from io import StringIO

from sqlalchemy import create_engine

def psql_insert_copy(table, conn, keys, data_iter):
    # gets a DBAPI connection that can provide a cursor
    dbapi_conn = conn.connection
    with dbapi_conn.cursor() as cur:
        s_buf = StringIO()
        writer = csv.writer(s_buf)
        writer.writerows(data_iter)
        s_buf.seek(0)

        columns = ', '.join('"{}"'.format(k) for k in keys)
        if table.schema:
            table_name = '{}.{}'.format(table.schema, table.name)
        else:
            table_name = table.name

        sql = 'COPY {} ({}) FROM STDIN WITH CSV'.format(
            table_name, columns)
        cur.copy_expert(sql=sql, file=s_buf)

engine = create_engine('postgresql://myusername:mypassword@myhost:5432/mydatabase')
df.to_sql('table_name', engine, method=psql_insert_copy)

Here is a concise 1-liner that does it, without using any external libraries.

# Given 0<a<b, returns the unique c such that 0<c<b and a*c == gcd(a,b) (mod b).
# In particular, if a,b are relatively prime, returns the inverse of a modulo b.
def invmod(a,b): return 0 if a==0 else 1 if b%a==0 else b - invmod(b%a,a)*b//a

Note that this is really just egcd, streamlined to return only the single coefficient of interest.

Firstly, I am not an authority on WebClient vs. HttpClient, specifically. Secondly, from your comments above, it seems to suggest that WebClient is Sync ONLY whereas HttpClient is both.

I did a quick performance test to find how WebClient (Sync calls), HttpClient (Sync and Async) perform. and here are the results.

I see that as a huge difference when thinking for future, i.e. long running processes, responsive GUI, etc. (add to the benefit you suggest by framework 4.5 - which in my actual experience is hugely faster on IIS)

you can use the example from Microsoft - for you without namespace:

using System.Xml.Linq;
using System.Xml.XPath;
var e = xdoc.XPathSelectElement("./Report/ReportInfo/Name");     

should do it

import numpy as np
array = np.arange(8) 
print("Original array : \n", array)
array = np.arange(8).reshape(2, 4)
print("New array : \n", array)

I guess what you're trying to do, is to keep the header fixed and to scroll the body content. You can scroll the content into 2 directions:

• horizontally: you won't be able to scroll the content horizontally unless you use a slider (a jQuery slider for example). I would recommend to avoid using a table in this case.
• vertically: you won't be able to achieve that with a tbody tag, because assigning display:block or display:inline-block will break the layout of the table.

Here's a solution using divs: JSFiddle

Explanation:

You have a sliding wrapper which will contain all the data.

Note the following:

.wrap_header{width:204px;}
.sliding_wrapper,
.wrap_body {width:221px;}

There's a difference of 17px because we need to take into consideration the width of the scrollbar.

You should use this code :

$(document).on("ready", function () {_x000D_
       _x000D_
        document.frmProduct.submit();_x000D_
    });

String locale = context.getResources().getConfiguration().locale.getCountry(); 

Is deprecated. Use this instead:

Locale locale;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
    locale = context.getResources().getConfiguration().getLocales().get(0);
} else {
    locale = context.getResources().getConfiguration().locale;
}

Wanted to comment on the last answer, but without login it’s only possible to make an answer:

To get rid of the "read only error" just stop the device immediately after it’s ready. My script looks as follows:

#!/bin/bash 
~/bin/AndroidSdk/tools/emulator @Nexus_6P_API_23 -no-boot-anim &
adb wait-for-device
adb shell stop
adb remount
adb push GmsCore.apk /system/priv-app
adb push GoogleServicesFramework.apk /system/priv-app
adb push GoogleLoginService.apk /system/priv-app
adb push Phonesky.apk /system/priv-app
adb shell start

You can use three things to mimic disabled:

1. HTML: readonly attribute (so that the value present in input can be used on form submission. Also the user can't change the input value)

2. CSS: 'pointer-events':'none' (blocking the user from clicking the input)

3. HTML: tabindex="-1" (blocking the user to navigate to the input from the keyboard)

Complementing the response of @Adrià Cidre you can do:

status=$(ssh -o BatchMode=yes -o ConnectTimeout=5 user@host echo ok 2>&1)

if [[ $status == ok ]] ; then
  echo auth ok, do something
elif [[ $status == "Permission denied"* ]] ; then
  echo no_auth
else
  echo other_error
fi

There's a difference between the raw queries and standard selects (between the DB::raw and DB::select methods).

You can do what you want using a DB::select and simply dropping in the ? placeholder much like you do with prepared statements (it's actually what it's doing).

A small example:

$results = DB::select('SELECT * FROM user WHERE username=?', ['jason']);

The second parameter is an array of values that will be used to replace the placeholders in the query from left to right.

@ECHO OFF
SETLOCAL
SET "string=string1 by string2.txt"
SET "string=%string:* by =%"
ECHO +%string%+

GOTO :EOF

The above SET command will remove the unwanted data. Result shown between + to demonstrate absence of spaces.

Formula: set var=%somevar:*string1=string2%

will assign to var the value of somevar with all characters up to string1 replaced by string2. The enclosing quotes in a set command ensure that any stray trailing spaces on the line are not included in the value assigned.

ASP.NET Core. Approach 1

If your Controller extends ControllerBase or Controller you can use Content(...) method:

[HttpGet]
public ContentResult Index() 
{
    return base.Content("<div>Hello</div>", "text/html");
}

ASP.NET Core. Approach 2

If you choose not to extend from Controller classes, you can create new ContentResult:

[HttpGet]
public ContentResult Index() 
{
    return new ContentResult 
    {
        ContentType = "text/html",
        Content = "<div>Hello World</div>"
    };
}

Legacy ASP.NET MVC Web API

Return string content with media type text/html:

public HttpResponseMessage Get()
{
    var response = new HttpResponseMessage();
    response.Content = new StringContent("<div>Hello World</div>");
    response.Content.Headers.ContentType = new MediaTypeHeaderValue("text/html");
    return response;
}

Like at least 1 other contributor here, I also have never liked having to add a extra "helper" column, which can create some hassles in various situations. I finally found a solution. There are a couple different formulas that you can use depending on needs and what is in the column, whether there are blank values, etc. For most of my needs, I have landed on using the following simple formula for the Conditional Formatting (CF) formula:

=MOD(Fixed(SUMPRODUCT(1/COUNTIF(CurrentRange,CurrentRange))),2)=0

I create a Named Range called "CurrentRange" using the following formula where [Sheet] is the sheet on which your data results, [DC] is the column with the values on which you want to band your data and [FR] is the first row that the data is in:

=[Sheet]!$[DC]$[FR]:INDIRECT("$[DC]$" & ROW())

The sheet reference and column reference will be based on the column that has the values you are evaluating. NOTE: You have to use a named range in the formula because will throw an error if you try to use range references directly in the CF rule formula.

Basically, the formula works by evaluating for each row the count of all of the unique values for that row and above to the top of your range. That value for each row essentially provides an ascending Unique ID for each new unique value. Then it uses that value in the place of the Row() function within the standard CF MOD function formula for simple alternating row colors (i.e. =Mod(Row(),2)=0).

See the following example that breaks down the formula to show the resulting components in columns to show what it is doing behind the scenes.

In this example, the CurrentRange named range is defined as:

=Sheet1$A$2:INDIRECT("$A$" & ROW())

The Unique ID column contains the following portion of the CF formula:

=Fixed(SUMPRODUCT(1/COUNTIF(CurrentRange,CurrentRange)))

You can see that, as of row 3, the count of unique values from that row and above in the "Color" column is 2 and it remains 2 in each subsequent row until row 6 when the formula finally encounters a 3rd unique value.

The Band column uses the remainder of the formula referring to the result in column B =MOD(B2,2) to show how it gets you to the 1s and 0s that can then be used for CF.

In the end, the point is, you don't need the extra columns. The entire formula can be used in the CF rule + a named range. For me, that means I can stick the basic formula in a template that I use to drop data in and not have to worry about messing with an extra column once the data is dropped in. It just works by default. Additionally, if you need to account for blanks or other complexities or large sets of data you can use other more complex formulas using frequency and match functions.

Hope this helps someone else avoid the frustration I have had for years!

I was having the same problem with 3 of 4 inline svgs I was using, and they only disappeared (in one case, partially) on IE11.

I had <meta http-equiv="x-ua-compatible" content="ie=edge"> on the page.

In the end, the problem was extra clipping paths on the svg file. I opened the files on Illustrator, removed the clipping path (normally at the bottom of the layers) and now they're all working.

try this:

import pylab
from scipy import misc

pylab.imshow(misc.lena(),cmap=pylab.gray())
pylab.show()

I would like to present another answer to this as the currently accepted answer doesn't work for me (I use LibreOffice). This solution should work in Excel, LibreOffice and OpenOffice:

First, insert a new row at the beginning of the sheet. Within that row, define the names you need:

Then, in the menu bar, go to View -> Freeze Cells -> Freeze First Row. It'll look like this now:

Now whenever you scroll down in the document, the first row will be "pinned" to the top:

A lot of insights in answers here, but i think an additional point is not clearly mentioned here explicitly. Quoting from python documentation https://docs.python.org/2/faq/programming.html#what-are-the-rules-for-local-and-global-variables-in-python

"In Python, variables that are only referenced inside a function are implicitly global. If a variable is assigned a new value anywhere within the function’s body, it’s assumed to be a local. If a variable is ever assigned a new value inside the function, the variable is implicitly local, and you need to explicitly declare it as ‘global’. Though a bit surprising at first, a moment’s consideration explains this. On one hand, requiring global for assigned variables provides a bar against unintended side-effects. On the other hand, if global was required for all global references, you’d be using global all the time. You’d have to declare as global every reference to a built-in function or to a component of an imported module. This clutter would defeat the usefulness of the global declaration for identifying side-effects."

Even when passing a mutable object to a function this still applies. And to me clearly explains the reason for the difference in behavior between assigning to the object and operating on the object in the function.

def test(l):
    print "Received", l , id(l)
    l = [0, 0, 0]
    print "Changed to", l, id(l)  # New local object created, breaking link to global l

l= [1,2,3]
print "Original", l, id(l)
test(l)
print "After", l, id(l)

gives:

Original [1, 2, 3] 4454645632
Received [1, 2, 3] 4454645632
Changed to [0, 0, 0] 4474591928
After [1, 2, 3] 4454645632

The assignment to an global variable that is not declared global therefore creates a new local object and breaks the link to the original object.

Better late than never, I suppose. I was motivated to develop this specifically because my Fedora scripts weren't working on the Mac. The problem is dependencies and Bash. Macs don't have them, or if they do, they are often somewhere else (another path). Dependency path manipulation in a cross-platform Bash script is a headache at best and a security risk at worst - so it's best to avoid their use, if possible.

The function get_realpath() below is simple, Bash-centric, and no dependencies are required. I uses only the Bash builtins echo and cd. It is also fairly secure, as everything gets tested at each stage of the way and it returns error conditions.

If you don't want to follow symlinks, then put set -P at the front of the script, but otherwise cd should resolve the symlinks by default. It's been tested with file arguments that are {absolute | relative | symlink | local} and it returns the absolute path to the file. So far we've not had any problems with it.

function get_realpath() {

if [[ -f "$1" ]]
then
    # file *must* exist
    if cd "$(echo "${1%/*}")" &>/dev/null
    then
        # file *may* not be local
        # exception is ./file.ext
        # try 'cd .; cd -;' *works!*
        local tmppwd="$PWD"
        cd - &>/dev/null
    else
        # file *must* be local
        local tmppwd="$PWD"
    fi
else
    # file *cannot* exist
    return 1 # failure
fi

# reassemble realpath
echo "$tmppwd"/"${1##*/}"
return 0 # success

}

You can combine this with other functions get_dirname, get_filename, get_stemname and validate_path. These can be found at our GitHub repository as realpath-lib (full disclosure - this is our product but we offer it free to the community without any restrictions). It also could serve as a instructional tool - it's well documented.

We've tried our best to apply so-called 'modern Bash' practices, but Bash is a big subject and I'm certain there will always be room for improvement. It requires Bash 4+ but could be made to work with older versions if they are still around.

There are several different ways to do that -- first, simply put it inside a form that points to where you want it to go:

<form action="/my/link/location" method="get">
    <input type="submit" value="Go to my link location" 
         name="Submit" id="frm1_submit" />
</form>

This has the advantage of working even without javascript turned on.

Second, use a stand-alone button with javascript:

<input type="submit" value="Go to my link location" 
    onclick="window.location='/my/link/location';" />       

This however, will fail in browsers without JavaScript (Note: this is really bad practice -- you should be using event handlers, not inline code like this -- this is just the simplest way of illustrating the kind of thing I'm talking about.)

The third option is to style an actual link like a button:

<style type="text/css">
.my_content_container a {
    border-bottom: 1px solid #777777;
    border-left: 1px solid #000000;
    border-right: 1px solid #333333;
    border-top: 1px solid #000000;
    color: #000000;
    display: block;
    height: 2.5em;
    padding: 0 1em;
    width: 5em;       
    text-decoration: none;       
}
// :hover and :active styles left as an exercise for the reader.
</style>

<div class="my_content_container">
    <a href="/my/link/location/">Go to my link location</a>
</div>

This has the advantage of working everywhere and meaning what you most likely want it to mean.

You probably want transparent as none is not a valid background-color value.

The CSS 2.1 spec states the following for the background-color property:

Value: <color> | transparent | inherit

<color> can be either a keyword or a numerical representation of a colour. Valid color keywords are:

aqua, black, blue, fuchsia, gray, green, lime, maroon, navy, olive, orange, purple, red, silver, teal, white, and yellow

transparent and inherit are valid keywords in their own right, but none is not.

1. Close the project you are working on with.
2. Delete your project's?DerivedData?folder. (This folder may inside your project's folder, or inside
   ~/Library/Developer/Xcode/DerivedData/
   (your project)/) or somewhere else that was setup by you.
3. restart your project.

You can use HTML,

foreach(...)
echo $data1 . '&nbsp' . $data2 . '&nbsp' . $data3 . '<br/>';

You can use the lsvirtualenv, in which you have two options "long" or "brief":

"long" option is the default one, it searches for any hook you may have around this command and executes it, which takes more time.

"brief" just take the virtualenvs names and prints it.

brief usage:

$ lsvirtualenv -b

long usage:

$ lsvirtualenv -l

if you don't have any hooks, or don't even know what i'm talking about, just use "brief".

You can use recursion to do this. I haven't verified the following, but it should give you the right idea:

MergeListOfDf = function( data , ... )
{
    if ( length( data ) == 2 ) 
    {
        return( merge( data[[ 1 ]] , data[[ 2 ]] , ... ) )
    }    
    return( merge( MergeListOfDf( data[ -1 ] , ... ) , data[[ 1 ]] , ... ) )
}

This variation of the query (as explained in other answers) worked for me.

SELECT
 COLUMN_NAME
FROM
 information_schema.COLUMNS
WHERE
 TABLE_NAME = 'city';

First argument in update method is SyntheticEvent object that contains common properties and methods to any event, it is not reference to React component where there is property props.

if you need pass argument to update method you can do it like this

onClick={ (e) => this.props.onClick(e, 'home', 'Home') }

and get these arguments inside update method

update(e, space, txt){
   console.log(e.target, space, txt);
}

Example

event.target gives you the native DOMNode, then you need to use the regular DOM APIs to access attributes. For instance getAttribute or dataset

<button 
  data-space="home" 
  className="home" 
  data-txt="Home" 
  onClick={ this.props.onClick } 
/> 
  Button
</button>

onClick(e) {
   console.log(e.target.dataset.txt, e.target.dataset.space);
}

Example

You could use a lookahead:

re.split(r'[ ](?=[A-Z]+\b)', input)

This will split at every space that is followed by a string of upper-case letters which end in a word-boundary.

Note that the square brackets are only for readability and could as well be omitted.

If it is enough that the first letter of a word is upper case (so if you would want to split in front of Hello as well) it gets even easier:

re.split(r'[ ](?=[A-Z])', input)

Now this splits at every space followed by any upper-case letter.

First, here's some sample data:

set.seed(1)
dat <- data.frame(one = rnorm(15),
                 two = sample(LETTERS, 15),
                 three = rnorm(15),
                 four = runif(15))
dat <- data.frame(lapply(dat, function(x) { x[sample(15, 5)] <- NA; x }))
head(dat)
#          one  two       three      four
# 1         NA    M  0.80418951 0.8921983
# 2  0.1836433    O -0.05710677        NA
# 3 -0.8356286    L  0.50360797 0.3899895
# 4         NA    E          NA        NA
# 5  0.3295078    S          NA 0.9606180
# 6 -0.8204684 <NA> -1.28459935 0.4346595

Here's our replacement:

dat[["four"]][is.na(dat[["four"]])] <- 0
head(dat)
#          one  two       three      four
# 1         NA    M  0.80418951 0.8921983
# 2  0.1836433    O -0.05710677 0.0000000
# 3 -0.8356286    L  0.50360797 0.3899895
# 4         NA    E          NA 0.0000000
# 5  0.3295078    S          NA 0.9606180
# 6 -0.8204684 <NA> -1.28459935 0.4346595

Alternatively, you can, of course, write dat$four[is.na(dat$four)] <- 0

xargs on MacOS doesn't have -d option, so this solution uses -0 instead.

Get ls to output one file per line, then translate newlines into nulls and tell xargs to use nulls as the delimiter:

ls -1 *mp3 | tr "\n" "\0" | xargs -0 mplayer

var objResponse1 = 
JsonConvert.DeserializeObject<List<RetrieveMultipleResponse>>(JsonStr);

Clickable smartphone link code:

The following link can be used to make a clickable phone link. You can copy the code below and paste it into your webpage, then edit with your phone number. This code may not work on all phones but does work for iPhone, Droid / Android, and Blackberry.

<a href="tel:1-847-555-5555">1-847-555-5555</a>

Phone number links can be used with the dashes, as shown above, or without them as well as in the following example:

<a href="tel:18475555555">1-847-555-5555</a>

It is also possible to use any text in the link as long as the phone number is set up with the "tel:18475555555" as in this example:

<a href="tel:18475555555">Click Here To Call Support 1-847-555-5555</a>

Below is a clickable telephone hyperlink you can check out. In most non-phone browsers this link will give you a "The webpage cannot be displayed" error or nothing will happen.

NOTE: The iPhone Safari browser will automatically detect a phone number on a page and will convert the text into a call link without using any of the code on this page.

WTAI smartphone link code: The WTAI or "Wireless Telephony Application Interface" link code is shown below. This code is considered to be the correct mobile phone protocol and will work on smartphones like Droid, however, it may not work for Apple Safari on iPhone and the above code is recommended.

<a href="wtai://wp/mc;18475555555">Click Here To Call Support 1-847-555-5555</a> 

for (var i in a) {
   console.log(a[i],i)
}

You should use input type="button" instead of input type="submit".

<form>
  <input type="button" value="Remove DUMMY" onclick="removeDummy(); "/>
 </form>

Edit: I totally misunderstood the question. In the browser, I would use setTimeout. If it was important that it ran in another thread, I would use Web Workers.

I do the following in my application:

Process process = new Process();
process.StartInfo.FileName = executable;
process.StartInfo.Arguments = arguments;
process.StartInfo.ErrorDialog = true;
process.StartInfo.WindowStyle = ProcessWindowStyle.Minimized;
process.Start();
process.WaitForExit(1000 * 60 * 5);    // Wait up to five minutes.

You could use a bit of jQuery:

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

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

try this. There are in general three ways to use mysqldump—

in order to dump a set of one or more tables,

shell> mysqldump [options] db_name [tbl_name ...]

a set of one or more complete databases

shell> mysqldump [options] --databases db_name ...

or an entire MySQL server—as shown here:

shell> mysqldump [options] --all-databases

Maybe it helps someone too:)

IIS webpage by using IP address

In IIS Management : Choose Site, then Bindings.

Add

• Type : http
• HostName : Empty
• Port : 80
• IP Address : Choose from drop-down menu the IP you need (usually there is only one IP)

Inherit the tableview delegate and datasource. Implement delegates what you need.

    override func viewDidLoad() {
        super.viewDidLoad()
        tableView.delegate = self
        tableView.dataSource = self
    }

And Finally implement this delegate

     func tableView(_ tableView: UITableView, didSelectRowAt  
     indexPath: IndexPath) {
     print("row selected : \(indexPath.row)")
  }

You can also have a look at FLTK (C++ and not plain C though)

FLTK (pronounced "fulltick") is a cross-platform C++ GUI toolkit for UNIX®/Linux® (X11), Microsoft® Windows®, and MacOS® X. FLTK provides modern GUI functionality without the bloat and supports 3D graphics via OpenGL® and its built-in GLUT emulation.

FLTK is designed to be small and modular enough to be statically linked, but works fine as a shared library. FLTK also includes an excellent UI builder called FLUID that can be used to create applications in minutes.

Here are some quickstart screencasts

[Happy New Year!]

Call $watch with true as the third argument:

$scope.$watch('form', function(newVal, oldVal){
    console.log('changed');
}, true);

By default when comparing two complex objects in JavaScript, they will be checked for "reference" equality, which asks if the two objects refer to the same thing, rather than "value" equality, which checks if the values of all the properties of those objects are equal.

Per the Angular documentation, the third parameter is for objectEquality:

When objectEquality == true, inequality of the watchExpression is determined according to the angular.equals function. To save the value of the object for later comparison, the angular.copy function is used. This therefore means that watching complex objects will have adverse memory and performance implications.

There are a lot of ways you can call a shell command from a Perl script, such as:

1. back tick ls which captures the output and gives back to you.
2. system system('ls');
3. open

Refer #17 here: Perl programming tips

As ping works, but telnetto port 80 does not, the HTTP port 80 is closed on your machine. I assume that your browser's HTTP connection goes through a proxy (as browsing works, how else would you read stackoverflow?). You need to add some code to your python program, that handles the proxy, like described here:

Using an HTTP PROXY - Python

Dont try this @ home

Add your application's package in "Filter Name" by clicking on "+" button on left top corner in logcat.

I think the best way is to test for functionality rather than versions. In some cases, this is trivial, not so in others.

eg:

try :
    # Do stuff
except : # Features weren't found.
    # Do stuff for older versions.

As long as you're specific in enough in using the try/except blocks, you can cover most of your bases.

You must use a unique filename(s). Like this

<img src="cars.png?1287361287" alt="">

But this technique means high server usage and bandwidth wastage. Instead, you should use the version number or date. Example:

<img src="cars.png?2020-02-18" alt="">

But you want it to never serve image from cache. For this, if the page does not use page cache, it is possible with PHP or server side.

<img src="cars.png?<?php echo time();?>" alt="">

However, it is still not effective. Reason: Browser cache ... The last but most effective method is Native JAVASCRIPT. This simple code finds all images with a "NO-CACHE" class and makes the images almost unique. Put this between script tags.

var items = document.querySelectorAll("img.NO-CACHE");
for (var i = items.length; i--;) {
    var img = items[i];
    img.src = img.src + '?' + Date.now();
}

USAGE

<img class="NO-CACHE" src="https://upload.wikimedia.org/wikipedia/commons/6/6a/JavaScript-logo.png" alt="">

:/$ cd etc/vim/
:/etc/vim$ sudo gvim gvimrc

After if - endif block, type

set guifont=Neep\ 10

save the file (:wq!). Here "Neep" (your choice) is the font style and "10" is respect size of the font. Then build the font - cache again.

:/etc/vim$ fc-cache -f -v

Your desired font will set to gvim.

Try this out:

grep "Killed process" /var/log/syslog

In MVC, assume you are searching record(s) based on your requirement or information. It is working properly.

[HttpPost]
[ActionName("Index")]
public ActionResult SearchRecord(FormCollection formcollection)
{       
    EmployeeContext employeeContext = new EmployeeContext();

    string searchby=formcollection["SearchBy"];
    string value=formcollection["Value"];

    if (formcollection["SearchBy"] == "Gender")
    {
        List<MvcApplication1.Models.Employee> emplist = employeeContext.Employees.Where(x => x.Gender == value).ToList();
        return View("Index", emplist);
    }
    else
    {
        List<MvcApplication1.Models.Employee> emplist = employeeContext.Employees.Where(x => x.Name == value).ToList();
        return View("Index", emplist);
    }         
}

Use this query:

ALTER TABLE tablename ADD columname DATATYPE(size);

And here is an example:

ALTER TABLE Customer ADD LastName VARCHAR(50);
