This is a place in which C++ has a strange rule. Before being able to compile a call to a function the compiler must know the function name, return value and all parameters. This can be done by adding a "prototype". In your case this simply means adding before main the following line:

int writeFile();

this tells the compiler that there exist a function named writeFile that will be defined somewhere, that returns an int and that accepts no parameters.

Alternatively you can define first the function writeFile and then main because in this case when the compiler gets to main already knows your function.

Note that this requirement of knowing in advance the functions being called is not always applied. For example for class members defined inline it's not required...

struct Foo {
    void bar() {
        if (baz() != 99) {
            std::cout << "Hey!";
        }
    }

    int baz() {
        return 42;
    }
};

In this case the compiler has no problem analyzing the definition of bar even if it depends on a function baz that is declared later in the source code.

As stated above, using 'click touchstart' will get the desired result. If you console.log(e) your clicks though, you may find that when jquery recognizes touch as a click - you will get 2 actions from click and touchstart. The solution bellow worked for me.

//if its a mobile device use 'touchstart'
if( /Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent) ) {
    deviceEventType = 'touchstart'
} else {
//If its not a mobile device use 'click'
    deviceEventType = 'click'
}

$(document).on(specialEventType, function(e){
    //code here
});

Simplest way to get the distinct values of a long list of comma delimited text would be to use a find an replace with UNION to get the distinct values.

SELECT 1
UNION SELECT 1
UNION SELECT 1
UNION SELECT 2
UNION SELECT 5
UNION SELECT 1
UNION SELECT 6

Applied to your long line of comma delimited text

• Find and replace every comma with UNION SELECT
• Add a SELECT in front of the statement

You now should have a working query

There is no: nono and no: yesyes. The truth is in the middle And no reasons to be scared because of the next version of Angular.

From a logical point of view, if You have a Component and You want to inform other components that something happens, an event should be fired and this can be done in whatever way You (developer) think it should be done. I don't see the reason why to not use it and i don't see the reason why to use it at all costs. Also the EventEmitter name suggests to me an event happening. I usually use it for important events happening in the Component. I create the Service but create the Service file inside the Component Folder. So my Service file becomes a sort of Event Manager or an Event Interface, so I can figure out at glance to which event I can subscribe on the current component.

I know..Maybe I'm a bit an old fashioned developer. But this is not a part of Event Driven development pattern, this is part of the software architecture decisions of Your particular project.

Some other guys may think that use Observables directly is cool. In that case go ahead with Observables directly. You're not a serial killer doing this. Unless you're a psychopath developer, So far the Program works, do it.

After wasting many hours, I came across this!

jquery-ui-touch-punch

It translates tap events as click events. Remember to load the script after jquery.

I got this working on the iPad and iPhone

$('#movable').draggable({containment: "parent"});

You can use the method Path.GetFileName(yourFileName); (MSDN) to just get the name of the file.

re: VMware Workstation support for physical disks vs virtual disks.

I run Player with the VM Disk files on their own dedicated fast hard drive, independent from the OS hard drive. This allows both the OS and Player to simultaneously independently read/write to their own drives, the performance difference is noticeable, and a second WD Black or Raptor or SSD is cheap. Placing the VM disk file on a second drive also works with Microsoft Virtual PC.

There is no way to do this in the GitHub web application. I believe to only way to do this is in the command line using git mv <old name> <new name> or by using a Git client(like SourceTree).

do this in two steps:

1. replace not letter characters with this regex:

   [\/\&%#\$]

2. replace quotes with this regex:

   [\"\']

and use preg_replace:

$stringWithoutNonLetterCharacters = preg_replace("/[\/\&%#\$]/", "_", $yourString);
$stringWithQuotesReplacedWithSpaces = preg_replace("/[\"\']/", " ", $stringWithoutNonLetterCharacters);

Probably the best way to do it is using rake to write the tasks you need and the just execute it via command line.

You can see a very helpful video at railscasts

Also take a look at this other resources:

• Rails Rake Tutorial

Maybe you can try this:

void foo(const char* str) 
{
    // Do something
}

foo("Hello")

It works for me

My problem concerning exclamation mark was in the section: "right click on project folder" - Properties - Libraries tab. There was an Error marked in red on a libray that probably wasn't in the right place so I removed it and ex. mark disappeared. The problem raised after deleting some old projects.

Arrays.asList(myArray).contains(false)

You just can't return the value directly because it is an async call. An async call means it is running in the background (actually scheduled for later execution) while your code continues to execute.

You also can't have such code in the class directly. It needs to be moved into a method or the constructor.

What you can do is not to subscribe() directly but use an operator like map()

export class DataComponent{
    someMethod() {
      return this.http.get(path).map(res => {
        return res.json();
      });
    }
}

In addition, you can combine multiple .map with the same Observables as sometimes this improves code clarity and keeps things separate. Example:

validateResponse = (response) => validate(response);

parseJson = (json) => JSON.parse(json);

fetchUnits() {
    return this.http.get(requestUrl).map(this.validateResponse).map(this.parseJson);
}

This way an observable will be return the caller can subscribe to

export class DataComponent{
    someMethod() {
      return this.http.get(path).map(res => {
        return res.json();
      });
    }

    otherMethod() {
      this.someMethod().subscribe(data => this.data = data);
    }
}

The caller can also be in another class. Here it's just for brevity.

data => this.data = data

and

res => return res.json()

are arrow functions. They are similar to normal functions. These functions are passed to subscribe(...) or map(...) to be called from the observable when data arrives from the response. This is why data can't be returned directly, because when someMethod() is completed, the data wasn't received yet.

On 2015-09-25 (after Xcode updates on 2015-09-18):

I used a non-lazy method, but it didn't work. The followings are my tries.

First,

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSExceptionDomains</key>
    <dict>
        <key>www.xxx.yyy.zzz</key>
        <dict>
            <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
            <true/>
            <key>NSTemporaryExceptionMinimumTLSVersion</key>
            <string>TLSv1.1</string>
            <key>NSIncludesSubdomains</key>
            <true/>
        </dict>
    </dict>
</dict>

And second,

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSExceptionDomains</key>
    <dict>
        <key>www.xxx.yyy.zzz</key>
        <dict>
            <key>NSExceptionAllowsInsecureHTTPLoads</key>
            <true/>
            <key>NSExceptionMinimumTLSVersion</key>
            <string>TLSv1.1</string>
            <key>NSIncludesSubdomains</key>
            <true/>
        </dict>
    </dict>
</dict>

Finally, I used the lazy method:

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

It might be a little insecure, but I couldn't find other solutions.

I had the same problem when writing layout file, after I deleted these two lines:

android:layout_marginLeft="@dimen/activity_horizontal_margin"
android:layout_marginRight="@dimen/activity_horizontal_margin"

the errors were gone.

#1- Run this to configure the region once and for all:

aws configure set region us-east-1 --profile admin

• Change admin next to the profile if it's different.

• Change us-east-1 if your region is different.

#2- Run your command again:

aws ecs list-container-instances --cluster default

DateTime dt = DateTime.Parse("01:00 pm"); //Time in string formate

TimeSpan time = new TimeSpan(); 

time = dt.TimeOfDay;

Console.WriteLine(time);

Result : 13:00:00

I had the same problem in Eclipse and I fixed it by changing the JRE from 64 bit to 32 bit:

Window > Preferences > Java > Installed JREs > Add... > Next > Directory > select "C:\Program Files (x86)\Java\jre1.8.0_65" instead of "C:\Program Files\Java\jre1.8.0_60"

3 years of experience later, I've come back to this question and would suggest to write it like this:

string output = new JavaScriptSerializer().Serialize(ListOfMyObject);

One line of code.

It must be at least 64 bits. Other than that it's implementation defined.

Strictly speaking, unsigned long long isn't standard in C++ until the C++0x standard. unsigned long long is a 'simple-type-specifier' for the type unsigned long long int (so they're synonyms).

The long long set of types is also in C99 and was a common extension to C++ compilers even before being standardized.

I had same problem. In my case MongoDB server wasn't running.

Try to open this in your web browser:

http://localhost:28017

If you can't, this means that you have to start MongoDB server.

Run mongod in another terminal tab. Then in your main tab run mongo which is is the shell that connects to your MongoDB server.

As mentioned here and here:

Set file encoding to UTF-8 and line-endings for new files to Unix, so that text files are saved in a format that is not specific to the Windows OS and most easily shared across heterogeneous developer desktops:

• Navigate to the Workspace preferences (General:Workspace)
• Change the Text File Encoding to UTF-8
• Change the New Text File Line Delimiter to Other and choose Unix from the pick-list

• Note: to convert the line endings of an existing file, open the file in Eclipse and choose File : Convert Line Delimiters to : Unix

Tip: You can easily convert existing file by selecting then in the Package Explorer, and then going to the menu entry File : Convert Line Delimiters to : Unix

sleep(3) is in unistd.h, not stdlib.h. Type man 3 sleep on your command line to confirm for your machine, but I presume you're on a Mac since you're learning Objective-C, and on a Mac, you need unistd.h.

This should be your answer

<div align="center">
 <img src="@Url.Content("~/images/image3.bmp")" alt="" align="right" style="float:right"/>
 <img src="@Url.Content("~/images/image1.bmp")" alt="" align="left" style="float:left" />
 <div id="content" align="center"> 
     <img src="@Url.Content("~/images/image2.bmp")" alt="" align="center" />
 </div>
 </div>

In addition to the accepted answer, I want to give you an example!

For instance, we all use

System.Console.WriteLine()

But Where is the code for System.Console.WriteLine!?
which is the code that actually puts the text on the console?

If you look at the first page of the documentation for the Console class, you‘ll see near the top the following: Assembly: mscorlib (in mscorlib.dll) This indicates that the code for the Console class is located in an assem-bly named mscorlib. An assembly can consist of multiple files, but in this case it‘s only one file, which is the dynamic link library mscorlib.dll.

The mscorlib.dll file is very important in .NET, It is the main DLL for class libraries in .NET, and it contains all the basic .NET classes and structures.

if you know C or C++, generally you need a #include directive at the top that references a header file. The include file provides function prototypes to the compiler. on the contrast The C# compiler does not need header files. During compilation, the C# compiler access the mscorlib.dll file directly and obtains information from metadata in that file concerning all the classes and other types defined therein.

The C# compiler is able to establish that mscorlib.dll does indeed contain a class named Console in a namespace named System with a method named WriteLine that accepts a single argument of type string.

The C# compiler can determine that the WriteLine call is valid, and the compiler establishes a reference to the mscorlib assembly in the executable.

by default The C# compiler will access mscorlib.dll, but for other DLLs, you‘ll need to tell the compiler the assembly in which the classes are located. These are known as references.

I hope that it's clear now!

From DotNetBookZero Charles pitzold

They both convert a String to a double value but wherease the parseDouble() method returns the primitive double value, the valueOf() method further converts the primitive double to a Double wrapper class object which contains the primitive double value.

The conversion from String to primitive double may throw NFE(NumberFormatException) if the value in String is not convertible into a primitive double.

I use SingleOrDefault in situations where my logic dictates that the will be either zero or one results. If there are more, it's an error situation, which is helpful.

For me it started working after selecting "Remove additional files at destination" in File publish options under settings on the publish dialog.

A simple string replace will do the job. Take a look at the example program below:

using System;

namespace NewLineThingy
{
    class Program
    {
        static void Main(string[] args)
        {
            string str = "fkdfdsfdflkdkfk@dfsdfjk72388389@kdkfkdfkkl@jkdjkfjd@jjjk@";
            str = str.Replace("@", "@" + Environment.NewLine);
            Console.WriteLine(str);
            Console.ReadKey();
        }
    }
}

You don't need the 'values' clause when using a 'select' as your source.

insert into table1 (col1, col2) 
select t1.col1, t2.col2 from oldtable1 t1, oldtable2 t2;

I can think of two things:

First, try loading the image with:

string strUri2 = String.Format(@"pack://application:,,,/MyAseemby;component/resources/main titles/{0}", CurrenSelection.TitleImage);
imgTitle.Source = new BitmapImage(new Uri(strUri2));

Maybe the problem is with WinForm's image resizing, if the image is stretched set Stretch on the image control to "Uniform" or "UnfirofmToFill".

Second option is that maybe the image is not aligned to the pixel grid, you can read about it on my blog at http://www.nbdtech.com/blog/archive/2008/11/20/blurred-images-in-wpf.aspx

Now we can add a picture to Excel directly and easely. Just follow these instructions:

1. Go to the Insert tab.
2. Click on the Pictures option (it’s in the illustrations group).
3. In the ‘Insert Picture’ dialog box, locate the pictures that you want to insert into a cell in Excel.
4. Click on the Insert button.
5. Re-size the picture/image so that it can fit perfectly within the cell.
6. Place the picture in the cell. A cool way to do this is to first press the ALT key and then move the picture with the mouse. It will snap and arrange itself with the border of the cell as soon it comes close to it.

If you have multiple images, you can select and insert all the images at once (as shown in step 4).

You can also resize images by selecting it and dragging the edges. In the case of logos or product images, you may want to keep the aspect ratio of the image intact. To keep the aspect ratio intact, use the corners of an image to resize it.

When you place an image within a cell using the steps above, it will not stick with the cell in case you resize, filter, or hide the cells. If you want the image to stick to the cell, you need to lock the image to the cell it’s placed n.

To do this, you need to follow the additional steps as shown below.

1. Right-click on the picture and select Format Picture.
2. In the Format Picture pane, select Size & Properties and with the options in Properties, select ‘Move and size with cells’.

Now you can move cells, filter it, or hide it, and the picture will also move/filter/hide.

NOTE:

This answer was taken from this link: Insert Picture into a Cell in Excel.

A Relation object passes unknown method calls through to an Eloquent query Builder, which is set up to only select the related objects. That Builder in turn passes unknown method calls through to its underlying query Builder.

This means you can use the exists() or count() methods directly from a relation object:

$model->relation()->exists(); // bool: true if there is at least one row
$model->relation()->count(); // int: number of related rows

Note the parentheses after relation: ->relation() is a function call (getting the relation object), as opposed to ->relation which a magic property getter set up for you by Laravel (getting the related object/objects).

Using the count method on the relation object (that is, using the parentheses) will be much faster than doing $model->relation->count() or count($model->relation) (unless the relation has already been eager-loaded) since it runs a count query rather than pulling all of the data for any related objects from the database, just to count them. Likewise, using exists doesn't need to pull model data either.

Both exists() and count() work on all relation types I've tried, so at least belongsTo, hasOne, hasMany, and belongsToMany.

This is a metadata change only: it is quick.

An observation: specify NULL or NOT NULL explicitly to avoid "accidents" if one of the SET ANSI_xx settings are different eg run in osql not SSMS for some reason

Adding the following block of code in web.config solves my problem

 <system.net>
    <defaultProxy enabled="false" >
    </defaultProxy>
  </system.net>

I had the same error, and I found out that the cause was because my computer disk was full. After deleting some unnecessary files, the error went away.

Just checked in Excel 2016 and this piece of code worked for me:

   Application.VBE.Windows("Immediate").SetFocus
   Application.SendKeys "^{END} ^+{HOME}{DEL}"

You can tweak and modify this code to make a better looking, more efficient contextmenu. As for modifying an existing contextmenu, I'm not sure how to do that... Check out this fiddle for an organized point of view. Also, try clicking the items in my contextmenu. They should alert you a few awesome messages. If they don't work, try something more... complex.

You can change the value of a bool all you want. As for an if:

if randombool == True:

works, but you can also use:

if randombool:

If you want to test whether something is false you can use:

if randombool == False

but you can also use:

if not randombool:

Sometimes just setting canvas's tabindex to '1' (or '0') works. But sometimes - it doesn't, for some strange reason.

In my case (ReactJS app, dynamic canvas el creation and mount) I need to call canvasEl.focus() to fix it. Maybe this is somehow related to React (my old app based on KnockoutJS works without '..focus()' )

I have the same problem in sqlDeveloper64-3.0.4.34 and sqlDeveloper64-3.1.07.42.

According to https://forums.oracle.com/forums/thread.jspa?threadID=2202388 it appears there is a bug in the JDBC driver having to do with 'Out Of Band Breaks' - basically a low level TCP issue.

The workaround is launch sql developer with JVM property -Doracle.net.disableOob=true I tried this solutions for 3.0 and 3.1 and it works.

So I just quote here the solution from forum:

I believe I have identified what is causing these issues for some users and not others. It appears there is a bug in the JDBC driver having to do with 'Out Of Band Breaks' - basically a low level TCP issue. The bug seems to manifest itself in a number of ways. So far I've identified using shared connections (particularly with Vista or Windows 7) and connecting over VPN (any OS) as common scenarios. In all cases, not having DBA access is also an issue.

First, let me explain why DBA access makes a difference. When we first access any particular data dictionary view, we first try to see if we can get access to the DBA version of the view (or is some cases tab$, etc). These views are much more efficient than the ordinary USER versions, so we want to use them if we can. We only check each DBA view once per session (and only when needed), but we can end up checking for access to a bunch of views.

The OOB bug seems to rear its head when we do this check. We should get a nice, simple response back from the database. However, in the scenarios where the bug is occurring, this low level network bug is instead causing an error to occur that puts the connection into an unusable state. This then results in all the Connection Closed errors. There does appear to be a workaround - the JDBC driver supports disabling OOB. However, doing so will affect the ability to cancel an executing statement, So I wouldn't recommend using the workaround in general, but it should solve the issue for the situations where users are running into this specific problem.

To enable the workaround, a Java system property needs to be set - oracle.net.disableOob=true. You can set this in two ways. The first is to pass it in on the command line as sqldeveloper -J-Doracle.net.disableOob=true. Of course, that only works if you are normally running from the command line. You can also add a line to the sqldeveloper.conf file (located under +sqldeveloper\bin+). There the line would be AddVMOption -Doracle.net.disableOob=true

We are looking into additional resolutions, but for now the workaround should enable you to work with SQL Developer.

You could make an AJAX call (likely using a library such as using Prototype.js or JQuery). AJAX can handle both GET and POST options.

My answer is an amalgamation of the above two with extension to drawing sphere of user-defined opacity and some annotation. It finds application in b-vector visualization on a sphere for magnetic resonance image (MRI). Hope you find it useful:

from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
import numpy as np

fig = plt.figure()
ax = fig.gca(projection='3d')

# draw sphere
u, v = np.mgrid[0:2*np.pi:50j, 0:np.pi:50j]
x = np.cos(u)*np.sin(v)
y = np.sin(u)*np.sin(v)
z = np.cos(v)
# alpha controls opacity
ax.plot_surface(x, y, z, color="g", alpha=0.3)


# a random array of 3D coordinates in [-1,1]
bvecs= np.random.randn(20,3)

# tails of the arrows
tails= np.zeros(len(bvecs))

# heads of the arrows with adjusted arrow head length
ax.quiver(tails,tails,tails,bvecs[:,0], bvecs[:,1], bvecs[:,2],
          length=1.0, normalize=True, color='r', arrow_length_ratio=0.15)

ax.set_xlabel('X-axis')
ax.set_ylabel('Y-axis')
ax.set_zlabel('Z-axis')

ax.set_title('b-vectors on unit sphere')

plt.show()

you can use preg_grep():

$a= array(
 'one',
 'two',
 'three',
 'four'
);

print_r( preg_grep( "/ONe/i" , $a ) );

It is also beneficial to store data into sessionStorage

// Save data to sessionStorage
sessionStorage.setItem('key', 'value');

// Get saved data from sessionStorage
var data = sessionStorage.getItem('key');

// Remove saved data from sessionStorage
sessionStorage.removeItem('key');

// Remove all saved data from sessionStorage
sessionStorage.clear();

You didn't bind all your bindings here

$sql = "SELECT SQL_CALC_FOUND_ROWS *, UNIX_TIMESTAMP(publicationDate) AS publicationDate     FROM comments WHERE articleid = :art 
ORDER BY " . mysqli_escape_string($order) . " LIMIT :numRows";

$st = $conn->prepare( $sql );
$st->bindValue( ":art", $art, PDO::PARAM_INT );

You've declared a binding called :numRows but you never actually bind anything to it.

UPDATE 2019: I keep getting upvotes on this and that reminded me of another suggestion

Double quotes are string interpolation in PHP, so if you're going to use variables in a double quotes string, it's pointless to use the concat operator. On the flip side, single quotes are not string interpolation, so if you've only got like one variable at the end of a string it can make sense, or just use it for the whole string.

In fact, there's a micro op available here since the interpreter doesn't care about parsing the string for variables. The boost is nearly unnoticable and totally ignorable on a small scale. However, in a very large application, especially good old legacy monoliths, there can be a noticeable performance increase if strings are used like this. (and IMO, it's easier to read anyway)

you can implement a helper doing something like that :

public static LocalDateTime convertUTCFRtoUTCZ(LocalDateTime dateTime) {
    ZoneId fr = ZoneId.of("Europe/Paris");
    ZoneId utcZ = ZoneId.of("Z");
    ZonedDateTime frZonedTime = ZonedDateTime.of(dateTime, fr);
    ZonedDateTime utcZonedTime = frZonedTime.withZoneSameInstant(utcZ);
    return utcZonedTime.toLocalDateTime();
}

Trying http://0.0.0.0:3000/routes on a Rails 5 API app (i.e.: JSON-only oriented) will (as of Rails beta 3) return

{"status":404,"error":"Not Found","exception":"#> 
<ActionController::RoutingError:...

However, http://0.0.0.0:3000/rails/info/routes will render a nice, simple HTML page with routes.

You can try this quick code

public static void cancelNotification(Context ctx, int notifyId) {
    String ns = Context.NOTIFICATION_SERVICE;
    NotificationManager nMgr = (NotificationManager) ctx.getSystemService(ns);
    nMgr.cancel(notifyId);
}

The JDK provides Collections.unmodifiableXXX methods, but in our opinion, these can be unwieldy and verbose; unpleasant to use everywhere you want to make defensive copies unsafe: the returned collections are only truly immutable if nobody holds a reference to the original collection inefficient: the data structures still have all the overhead of mutable collections, including concurrent modification checks, extra space in hash tables, etc.

You can try this simple way for combining columns:

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

here is my answer:

public class WigetControl {
private Resources res;

public WigetControl(Resources res) 
{
    this.res = res;
}

public void setButtonDisable(Button mButton)
{
    mButton.setBackgroundColor(res.getColor(R.color.loginbutton_unclickable));
    mButton.setEnabled(false);
}

}

and the call can be like this:

        WigetControl control = new WigetControl(getResources());
        control.setButtonDisable(btNext);

docker run -t -i -p 8246:8080 -e SWAGGER_JSON=/var/specs/openapi.yml -v $PWD/docs/specs:/var/specs swaggerapi/swagger-ui

The answer is to DISABLE "Enable auto-completion on each input". Tested and works perfectly.

What you should be looking at is Import-Csv

Once you import the CSV you can use the column header as the variable.

Example CSV:

Name  | Phone Number | Email
Elvis | 867.5309     | [email protected]
Sammy | 555.1234     | [email protected]

Now we will import the CSV, and loop through the list to add to an array. We can then compare the value input to the array:

$Name = @()
$Phone = @()

Import-Csv H:\Programs\scripts\SomeText.csv |`
    ForEach-Object {
        $Name += $_.Name
        $Phone += $_."Phone Number"
    }

$inputNumber = Read-Host -Prompt "Phone Number"

if ($Phone -contains $inputNumber)
    {
    Write-Host "Customer Exists!"
    $Where = [array]::IndexOf($Phone, $inputNumber)
    Write-Host "Customer Name: " $Name[$Where]
    }

And here is the output:

Add LinearLayout before EditText in your XML.

<LinearLayout 
    android:focusable="true"
    android:focusableInTouchMode="true" 
    android:clickable="true"
    android:layout_width="0px"
    android:layout_height="0px" />

Or you can do this same thing by adding these lines to view before your 'EditText'.

<Button
    android:id="@+id/btnSearch"
    android:layout_width="50dp"
    android:layout_height="50dp"
    android:focusable="true"
    android:focusableInTouchMode="true"
    android:gravity="center"
    android:text="Quick Search"
    android:textColor="#fff"
    android:textSize="13sp"
    android:textStyle="bold" />

<EditText
    android:id="@+id/edtSearch"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_centerVertical="true"
    android:layout_marginRight="5dp"
    android:gravity="left"
    android:hint="Name"
    android:maxLines="1"
    android:singleLine="true"
    android:textColorHint="@color/blue"
    android:textSize="13sp"
    android:textStyle="bold" />

there is no timeout, by default.

By using jquery function .closest(element) and .find(...).

Getting the parent element and looking for the child.

Finally, do the function needed.

$("#form").closest('form').find("input[type=text], textarea").val("");

I understand using a global variable is sometimes the most convenient thing to do, especially in cases where usage of class makes the easiest thing so much harder (e.g., multiprocessing). I ran into the same problem with declaring global variables and figured it out with some experiments.

The reason that g_c was not changed by the run function within your class is that the referencing to the global name within g_c was not established precisely within the function. The way Python handles global declaration is in fact quite tricky. The command global g_c has two effects:

1. Preconditions the entrance of the key "g_c" into the dictionary accessible by the built-in function, globals(). However, the key will not appear in the dictionary until after a value is assigned to it.

2. (Potentially) alters the way Python looks for the variable g_c within the current method.

The full understanding of (2) is particularly complex. First of all, it only potentially alters, because if no assignment to the name g_c occurs within the method, then Python defaults to searching for it among the globals(). This is actually a fairly common thing, as is the case of referencing within a method modules that are imported all the way at the beginning of the code.

However, if an assignment command occurs anywhere within the method, Python defaults to finding the name g_c within local variables. This is true even when a referencing occurs before an actual assignment, which will lead to the classic error:

UnboundLocalError: local variable 'g_c' referenced before assignment

Now, if the declaration global g_c occurs anywhere within the method, even after any referencing or assignment, then Python defaults to finding the name g_c within global variables. However, if you are feeling experimentative and place the declaration after a reference, you will be rewarded with a warning:

SyntaxWarning: name 'g_c' is used prior to global declaration

If you think about it, the way the global declaration works in Python is clearly woven into and consistent with how Python normally works. It's just when you actually want a global variable to work, the norm becomes annoying.

Here is a code that summarizes what I just said (with a few more observations):

g_c = 0
print ("Initial value of g_c: " + str(g_c))
print("Variable defined outside of method automatically global? "
      + str("g_c" in globals()))

class TestClass():
    def direct_print(self):
        print("Directly printing g_c without declaration or modification: "
              + str(g_c))
        #Without any local reference to the name
        #Python defaults to search for the variable in globals()
        #This of course happens for all the module names you import

    def mod_without_dec(self):
        g_c = 1
        #A local assignment without declaring reference to global variable
        #makes Python default to access local name
        print ("After mod_without_dec, local g_c=" + str(g_c))
        print ("After mod_without_dec, global g_c=" + str(globals()["g_c"]))


    def mod_with_late_dec(self):
        g_c = 2
        #Even with a late declaration, the global variable is accessed
        #However, a syntax warning will be issued
        global g_c
        print ("After mod_with_late_dec, local g_c=" + str(g_c))
        print ("After mod_with_late_dec, global g_c=" + str(globals()["g_c"]))

    def mod_without_dec_error(self):
        try:
            print("This is g_c" + str(g_c))
        except:
            print("Error occured while accessing g_c")
            #If you try to access g_c without declaring it global
            #but within the method you also alter it at some point
            #then Python will not search for the name in globals()
            #!!!!!Even if the assignment command occurs later!!!!!
        g_c = 3

    def sound_practice(self):
        global g_c
        #With correct declaration within the method
        #The local name g_c becomes an alias for globals()["g_c"]
        g_c = 4
        print("In sound_practice, the name g_c points to: " + str(g_c))


t = TestClass()
t.direct_print()
t.mod_without_dec()
t.mod_with_late_dec()
t.mod_without_dec_error()
t.sound_practice()

I noticed that Eemuli said that you can't change the log level after they are created - and while that might be the design, it isn't entirely true.

I ran into a situation where I was using a library that logged to slf4j - and I was using the library while writing a maven mojo plugin.

Maven uses a (hacked) version of the slf4j SimpleLogger, and I was unable to get my plugin code to reroute its logging to something like log4j, which I could control.

And I can't change the maven logging config.

So, to quiet down some noisy info messages, I found I could use reflection like this, to futz with the SimpleLogger at runtime.

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.slf4j.spi.LocationAwareLogger;
    try
    {
        Logger l = LoggerFactory.getLogger("full.classname.of.noisy.logger");  //This is actually a MavenSimpleLogger, but due to various classloader issues, can't work with the directly.
        Field f = l.getClass().getSuperclass().getDeclaredField("currentLogLevel");
        f.setAccessible(true);
        f.set(l, LocationAwareLogger.WARN_INT);
    }
    catch (Exception e)
    {
        getLog().warn("Failed to reset the log level of " + loggerName + ", it will continue being noisy.", e);
    }

Of course, note, this isn't a very stable / reliable solution... as it will break the next time the maven folks change their logger.

The code below does just that. The below is a working example to log into a game. I made a similar file to log in into Yahoo and a kurzweilai.net forum.

Just copy the login form from any webpage's source code. Add value= "your user name" and value = "your password". Normally the -input- elements in the source code do not have the value attribute, and sometime, you will see something like that: value=""

Save the file as a html on a local machine double click it, or make a bat/cmd file to launch and close them as required.

    <!doctype html>
    <!-- saved from url=(0014)about:internet -->

    <html>
    <title>Ikariam Autologin</title>
    </head>
    <body>
    <form id="loginForm" name="loginForm" method="post"    action="http://s666.en.ikariam.com/index.php?action=loginAvatar&function=login">
    <select name="uni_url" id="logServer" class="validate[required]">
    <option  class=""  value="s666.en.ikariam.com" fbUrl=""  cookieName=""  >
            Test_en
    </option>
    </select>
    <input id="loginName" name="name" type="text" value="PlayersName" class="" />
    <input id="loginPassword" name="password" type="password" value="examplepassword" class="" />
    <input type="hidden" id="loginKid" name="kid" value=""/>
                        </form>
  <script>document.loginForm.submit();</script>       
  </body></html>

Note that -script- is just -script-. I found there is no need to specify that is is JavaScript. It works anyway. I also found out that a bare-bones version that contains just two input filds: userName and password also work. But I left a hidded input field etc. just in case. Yahoo mail has a lot of hidden fields. Some are to do with password encryption, and it counts login attempts.

Apparently in Android 2.2 there is a bug with SimpleDateFormat.

In order to use month names you have to define them yourself in your resources:

<string-array name="month_names">
    <item>January</item>
    <item>February</item>
    <item>March</item>
    <item>April</item>
    <item>May</item>
    <item>June</item>
    <item>July</item>
    <item>August</item>
    <item>September</item>
    <item>October</item>
    <item>November</item>
    <item>December</item>
</string-array>

And then use them in your code like this:

/**
 * Get the month name of a Date. e.g. January for the Date 2011-01-01
 * 
 * @param date
 * @return e.g. "January"
 */
public static String getMonthName(Context context, Date date) {

    /*
     * Android 2.2 has a bug in SimpleDateFormat. Can't use "MMMM" for
     * getting the Month name for the given Locale. Thus relying on own
     * values from string resources
     */

    String result = "";

    Calendar cal = Calendar.getInstance();
    cal.setTime(date);
    int month = cal.get(Calendar.MONTH);

    try {
        result = context.getResources().getStringArray(R.array.month_names)[month];
    } catch (ArrayIndexOutOfBoundsException e) {
        result = Integer.toString(month);
    }

    return result;
}

On the command line:

php -i | grep sourceguardian

If it's there, then you'll get some text. If not, you won't get a thing.

Uninstall your android studio in control panel and remove all data in your file manager about android studio.

In Eclipse, go to Window → Preferences → General → Network Connections. In the Active Provider combo box, choose "Manual". In the proxy entries table, for each entry click "Edit..." and supply your proxy host, port, username and password details.

If it's a new google account, you have to send an email (the first one) through the regular user interface. After that you can use your application/robot to send messages.

My site configuration file is example.conf in sites-available folder So you can create a symbolic link as

I wouldn't suggest using the Eclipse tool to generate the WS Client because I had bad experience with it:

I am not really sure if this matters but I had to consume a WS written in .NET. When I used the Eclipse's "New Web Service Client" tool it generated the Java classes using Axis (version 1.x) which as you can check is old (last version from 2006). There is a newer version though that is has some major changes but Eclipse doesn't use it.

Why the old version of Axis matters you'll say? Because when using OpenJDK you can run into some problems like missing cryptography algorithms in OpenJDK that are presented in the Oracle's JDK and some libraries like this one depend on them.

So I just used the wsimport tool and ended my headaches.

I know this question is older and others already explained it well, I would like to give an example problem which explains the same in simple terms.

Problem: Writing the 1's table.

Solution: -

By Imperative style: =>

    1*1=1
    1*2=2
    1*3=3
    .
    .
    .
    1*n=n 

By Functional style: =>

    1
    2
    3
    .
    .
    .
    n

Explanation in Imperative style we write the instructions more explicitly and which can be called as in more simplified manner.

Where as in Functional style, things which are self-explanatory will be ignored.

.cancela,.cancela:link,.cancela:visited,.cancela:hover,.cancela:focus,.cancela:active{
    color: inherit;
    text-decoration: none;
}

I felt it necessary to post the above class definition, many of the answers on SO miss some of the states

Set the asp_tags = On and short_open_tag = On in both the files \apache\Apache2.2.21\bin\php.ini and \bin\php\php5.3.8\php.ini and then restart the apache server.

I would checkout the remote file from the "master" (the remote/origin repository) like this:

git checkout master <FileWithPath>

Example: git checkout master components/indexTest.html

I only needed to uncheck 'Automatically manage signing', check it again, and rebuild.

Using shell parameter expansion %% *

Here is another solution using shell parameter expansion. It takes care of multiple spaces after the first word. Handling spaces in front of the first word requires one additional expansion.

string='word1    word2'
echo ${string%% *}
word1

string='word1    word2      '
echo ${string%% *}
word1

Explanation

The %% signifies deleting the longest possible match of * (a space followed by any number of whatever other characters) in the trailing part of string.

https://cdnjs.com/libraries/popper.js does not look like a right src for popper, it does not specify the file

with bootstrap 4 I am using this

<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.11.0/umd/popper.min.js" integrity="sha384-b/U6ypiBEHpOf/4+1nzFpr53nxSS+GLCkfwBdFNTxtclqqenISfwAzpKaMNFNmj4" crossorigin="anonymous"></script>

and it is working perfectly fine, give it a try

Try this code in jquery

$(document).ready(function(){
  $("a").click(function(){
  var id=$(this).attr('href');
  var value=$(id).text();
  $(".target").text(value);
  });
});

Another one-liner:

x.split(".").slice(0, -1).join(".")

Adding to @Greg Hewgill answer: if you want to be able to match both date-time and only date, you can make the "time" part of the regex optional:

(\d{4})-(\d{2})-(\d{2})( (\d{2}):(\d{2}):(\d{2}))?

this way you will match both 2008-09-01 12:35:42 and 2008-09-01

Actually it's possible, despite what's being said in other answers. If you have a FrameLayout, and want to position a child item to the bottom, you can use android:layout_gravity="bottom" and that is going to align that child to the bottom of the FrameLayout.

I know it works because I'm using it. I know is late, but it might come handy to others since this ranks in the top positions on google

button2.Enabled == true ; must be button2.Enabled = true ;.

You have a compare == where you should have an assign =.

Try sys.path[0].

To quote from the Python docs:

As initialized upon program startup, the first item of this list, path[0], is the directory containing the script that was used to invoke the Python interpreter. If the script directory is not available (e.g. if the interpreter is invoked interactively or if the script is read from standard input), path[0] is the empty string, which directs Python to search modules in the current directory first. Notice that the script directory is inserted before the entries inserted as a result of PYTHONPATH.

Source: https://docs.python.org/library/sys.html#sys.path

If you also need to match the content of the link itself, use text():

//a[contains(@href,"/some_link")][text()="Click here"]

If you want an alternative image instead of a text, you can as well use php:

$file="smiley.gif";
$alt_file="alt.gif";
if(file_exist($file)){
     echo "<img src='".$file."' border="0" />";
}else if($alt_file){
     // the alternative file too might not exist not exist
     echo "<img src='".$alt_file."' border="0" />";
}else{
  echo "smily face";
}

You are correct. You did exactly the right thing, checking the query plan rather than trying to second-guess the optimiser. :-)

As mentioned in an above answer, the Scala List is an immutable collection. You can create an empty list with .empty[A]. Then you can use a method :+ , +: or :: in order to add element to the list.

scala> val strList = List.empty[String]
strList: List[String] = List()

scala> strList:+ "Text"
res3: List[String] = List(Text)

scala> val mapList = List.empty[Map[String, Any]]
mapList: List[Map[String,Any]] = List()

scala> mapList :+ Map("1" -> "ok")
res4: List[Map[String,Any]] = List(Map(1 -> ok))

Depending on what you want you might be interested in the SPL Object Storage class.

http://php.net/manual/en/class.splobjectstorage.php

It lets you use objects as keys, has an interface to count, get the hash and other goodies.

$s = new SplObjectStorage;
$o1 = new stdClass;
$o2 = new stdClass;
$o2->foo = 'bar';

$s[$o1] = 'baz';
$s[$o2] = 'bingo';

echo $s[$o1]; // 'baz'
echo $s[$o2]; // 'bingo'

You can use argv npm module (install it by running npm install argv --save) for getting params in your webpack.config.js file and as for production you use -p flag "build": "webpack -p", you can add condition in webpack.config.js file like below

plugins: [
    new webpack.DefinePlugin({
        'process.env':{
            'NODE_ENV': argv.p ? JSON.stringify('production') : JSON.stringify('development')
        }
    })
]

And thats it.

My hint:

1. FIND IF EXISTS in .env:

   APP_URL=http://yourhost.dev

2. REPLACE TO (OR ADD)

   APP_DOMAIN=yourhost.dev

3. FIND in config/app.php:

   'url' => env('APP_URL'),

4. REPLACE TO

   'domain' => env('APP_DOMAIN'),

   'url' => 'http://' . env('APP_DOMAIN'),

5. USE:

   Config::get('app.domain'); // yourhost.dev

   Config::get('app.url') // http://yourhost.dev

6. Do your magic!

Use -w in the command: psql -h localhost -p 5432 -U user -w

SELECT cast( cast(round(37.0/38.0,2) AS DECIMAL(18,2)) as varchar(100)) + ' %'

RESULT:  0.97 %

Rename the closing function as 'hide', for example and it will work.

function hide() {
    if(document.getElementById('benefits').style.display=='block') {
      document.getElementById('benefits').style.display='none';
    }
} 

Use show create table tbl_name to view the foreign keys

You can use this syntax to drop a foreign key:

ALTER TABLE tbl_name DROP FOREIGN KEY fk_symbol

There's also more information here (see Frank Vanderhallen post): http://dev.mysql.com/doc/refman/5.5/en/innodb-foreign-key-constraints.html

I don't think there is a good way of doing what you want. And if you think about it I don't think this is what you really want.

If you would have a dynamic enum, it also means you have to feed it with a dynamic value when you reference it. Maybe with a lot of magic you could achieve some sort of IntelliSense that would take care of this and generate an enum for you in a DLL file. But consider the amount of work it would take, how uneffective it would be to access the database to fetch IntelliSense information as well as the nightmare of version controlling the generated DLL file.

If you really don't want to manually add the enum values (you'll have to add them to the database anyway) use a code generation tool instead, for example T4 templates. Right click+run and you got your enum statically defined in code and you get all the benefits of using enums.

maybe this can solve the problem: matplotlib, define size of a grid on a plot

ax.grid(True, which='both')

The truth is that the grid is working, but there's only one v-grid in 00:00 and no grid in others. I meet the same problem that there's only one grid in Nov 1 among many days.

Both answers are correct. If you user .TO -method then the semicolumn is OK - but not for the addrecipients-method. There you need to split, e.g. :

                Dim Splitter() As String
                Splitter = Split(AddrMail, ";")
                For Each Dest In Splitter
                    .Recipients.Add (Trim(Dest))
                Next

You can simply use one of the system dependent end-of-file indicators ( d for Unix/Linux/Ubuntu, z for windows) to make the while statement false. This should get you out of the loop nicely. :)

If you just want to know the mean, you can use

summary(results)

It will give you more information than expected.

ex) Mininum value, 1st Qu., Median, Mean, 3rd Qu. Maxinum value, number of NAs.

Furthermore, If you want to get mean values of each column, you can simply use the method below.

mean(results$columnName, na.rm = TRUE)

That will return mean value. (you have to change 'columnName' to your variable name

You can simply use the zoom property:

#myContainer{
    zoom: 0.5;
    -moz-transform: scale(0.5);
}

Where myContainer contains all the elements you're editing. This is supported in all major browsers.

I had the same problem: I love the resolve object, but that only works for the content of ng-view. What if you have controllers (for top-level nav, let's say) that exist outside of ng-view and which need to be initialized with data before the routing even begins to happen? How do we avoid mucking around on the server-side just to make that work?

Use manual bootstrap and an angular constant. A naiive XHR gets you your data, and you bootstrap angular in its callback, which deals with your async issues. In the example below, you don't even need to create a global variable. The returned data exists only in angular scope as an injectable, and isn't even present inside of controllers, services, etc. unless you inject it. (Much as you would inject the output of your resolve object into the controller for a routed view.) If you prefer to thereafter interact with that data as a service, you can create a service, inject the data, and nobody will ever be the wiser.

Example:

//First, we have to create the angular module, because all the other JS files are going to load while we're getting data and bootstrapping, and they need to be able to attach to it.
var MyApp = angular.module('MyApp', ['dependency1', 'dependency2']);

// Use angular's version of document.ready() just to make extra-sure DOM is fully 
// loaded before you bootstrap. This is probably optional, given that the async 
// data call will probably take significantly longer than DOM load. YMMV.
// Has the added virtue of keeping your XHR junk out of global scope. 
angular.element(document).ready(function() {

    //first, we create the callback that will fire after the data is down
    function xhrCallback() {
        var myData = this.responseText; // the XHR output

        // here's where we attach a constant containing the API data to our app 
        // module. Don't forget to parse JSON, which `$http` normally does for you.
        MyApp.constant('NavData', JSON.parse(myData));

        // now, perform any other final configuration of your angular module.
        MyApp.config(['$routeProvider', function ($routeProvider) {
            $routeProvider
              .when('/someroute', {configs})
              .otherwise({redirectTo: '/someroute'});
          }]);

        // And last, bootstrap the app. Be sure to remove `ng-app` from your index.html.
        angular.bootstrap(document, ['NYSP']);
    };

    //here, the basic mechanics of the XHR, which you can customize.
    var oReq = new XMLHttpRequest();
    oReq.onload = xhrCallback;
    oReq.open("get", "/api/overview", true); // your specific API URL
    oReq.send();
})

Now, your NavData constant exists. Go ahead and inject it into a controller or service:

angular.module('MyApp')
    .controller('NavCtrl', ['NavData', function (NavData) {
        $scope.localObject = NavData; //now it's addressable in your templates 
}]);

Of course, using a bare XHR object strips away a number of the niceties that $http or JQuery would take care of for you, but this example works with no special dependencies, at least for a simple get. If you want a little more power for your request, load up an external library to help you out. But I don't think it's possible to access angular's $http or other tools in this context.

(SO related post)

Here's one just as fast as the split() and the replace methods, which are a tiny bit faster than the regex method (in Chrome and Firefox both).

let num = 0;
let str = "str1,str2,str3,str4";
//Note: Pre-calculating `.length` is an optimization;
//otherwise, it recalculates it every loop iteration.
let len = str.length;
//Note: Don't use a `for (... of ...)` loop, it's slow!
for (let charIndex = 0; charIndex < len; ++charIndex) {
  if (str[charIndex] === ',') {
    ++num;
  }
}

The playbook script task will generate stdout just like the non-playbook command, it just needs to be saved to a variable using register. Once we've got that, the debug module can print to the playbook output stream.

tasks:
- name: Hello yourself
  script: test.sh
  register: hello

- name: Debug hello
  debug: var=hello

- name: Debug hello.stdout as part of a string
  debug: "msg=The script's stdout was `{{ hello.stdout }}`."

Output should look something like this:

TASK: [Hello yourself] ******************************************************** 
changed: [MyTestHost]

TASK: [Debug hello] *********************************************************** 
ok: [MyTestHost] => {
    "hello": {
        "changed": true, 
        "invocation": {
            "module_args": "test.sh", 
            "module_name": "script"
        }, 
        "rc": 0, 
        "stderr": "", 
        "stdout": "Hello World\r\n", 
        "stdout_lines": [
            "Hello World"
        ]
    }
}

TASK: [Debug hello.stdout as part of a string] ******************************** 
ok: [MyTestHost] => {
    "msg": "The script's stdout was `Hello World\r\n`."
}

I am getting this issue when using owl carousal and scrolling the images.

So get solved just adding below CSS in your page.

.owl-carousel {
-ms-touch-action: pan-y;
touch-action: pan-y;
}

or

.owl-carousel {
-ms-touch-action: none;
touch-action: none;
}

If you want to do this outside of the cqlsh tool you can query the schema_keyspaces table in the system keyspace. There's also a table called schema_columnfamilies which contains information about all tables.

The DESCRIBE and SHOW commands only work in cqlsh and cassandra-cli.

json works with Unicode text in Python 3 (JSON format itself is defined only in terms of Unicode text) and therefore you need to decode bytes received in HTTP response. r.headers.get_content_charset('utf-8') gets your the character encoding:

#!/usr/bin/env python3
import io
import json
from urllib.request import urlopen

with urlopen('https://httpbin.org/get') as r, \
     io.TextIOWrapper(r, encoding=r.headers.get_content_charset('utf-8')) as file:
    result = json.load(file)
print(result['headers']['User-Agent'])

It is not necessary to use io.TextIOWrapper here:

#!/usr/bin/env python3
import json
from urllib.request import urlopen

with urlopen('https://httpbin.org/get') as r:
    result = json.loads(r.read().decode(r.headers.get_content_charset('utf-8')))
print(result['headers']['User-Agent'])

One thing to note is that not all libraries will use the same meaning for pi, of course, so it never hurts to know what you're using. For example, the symbolic math library Sympy's representation of pi is not the same as math and numpy:

import math
import numpy
import scipy
import sympy

print(math.pi == numpy.pi)
> True
print(math.pi == scipy.pi)
> True
print(math.pi == sympy.pi)
> False

Shameless plug, but you can use findHandlerJS

To use it you just have to include findHandlersJS (or just copy&paste the raw javascript code to chrome's console window) and specify the event type and a jquery selector for the elements you are interested in.

For your example you could quickly find the event handlers you mentioned by doing

findEventHandlers("click", "#el")
findEventHandlers("mouseover", "#el")

This is what gets returned:

• element
  The actual element where the event handler was registered in
• events
  Array with information about the jquery event handlers for the event type that we are interested in (e.g. click, change, etc)
  • handler
    Actual event handler method that you can see by right clicking it and selecting Show function definition
  • selector
    The selector provided for delegated events. It will be empty for direct events.
  • targets
    List with the elements that this event handler targets. For example, for a delegated event handler that is registered in the document object and targets all buttons in a page, this property will list all buttons in the page. You can hover them and see them highlighted in chrome.

You can try it here

The GetProperty/GetValue does not work for Json data, it always generate a null exception, however, you may try this approach:

Serialize your object using JsonConvert:

var z = Newtonsoft.Json.JsonConvert.DeserializeObject(Convert.ToString(request));

Then access it directly casting it back to string:

var pn = (string)z["DynamicFieldName"];

It may work straight applying the Convert.ToString(request)["DynamicFieldName"], however I haven't tested.

You need to do a while loop to get the result from the SQL query, like this:

require_once('db.php');  
$sql="SELECT * FROM  modul1open WHERE idM1O>=(SELECT FLOOR( MAX( idM1O ) * RAND( ) )    
FROM modul1open) ORDER BY idM1O LIMIT 1";

$result = mysql_query($sql);

while($row = mysql_fetch_array($result, MYSQL_ASSOC)) {

    // If you want to display all results from the query at once:
    print_r($row);

    // If you want to display the results one by one
    echo $row['column1'];
    echo $row['column2']; // etc..

}

Also I would strongly recommend not using mysql_* since it's deprecated. Instead use the mysqli or PDO extension. You can read more about that here.

Please change your project-level build.gradle file in which you have to change your dependencies class path of google-services or build.gradle path.

buildscript {

    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
        classpath 'com.google.gms:google-services:4.0.1'
    }
}

Yes. Java doubles will hold their precision better than your given epsilon of 0.00001.

Any rounding error that occurs due to the storage of floating point values will occur smaller than 0.00001. I regularly use 1E-6 or 0.000001 for a double epsilon in Java with no trouble.

On a related note, I like the format of epsilon = 1E-5; because I feel it is more readable (1E-5 in Java = 1 x 10^-5). 1E-6 is easy to distinguish from 1E-5 when reading code whereas 0.00001 and 0.000001 look so similar when glancing at code I think they are the same value.

If you want disable it in Global, you can write a custom middleware, like this

from django.utils.deprecation import MiddlewareMixin

class DisableCsrfCheck(MiddlewareMixin):

    def process_request(self, req):
        attr = '_dont_enforce_csrf_checks'
        if not getattr(req, attr, False):
            setattr(req, attr, True)

then add this class youappname.middlewarefilename.DisableCsrfCheck to MIDDLEWARE_CLASSES lists, before django.middleware.csrf.CsrfViewMiddleware

Select A.ARIDNR,A.LIEFNR
from Table A
join Table B
on A.ARIDNR = B.ARIDNR
and A.LIEFNR<> B.LIEFNR
group by A.ARIDNR,A.LIEFNR

Swift 4, 4.2 and 5.

  @IBOutlet weak var lblUnderLine: UILabel!

I need to underline particular text in UILabel. So, find range and set attributes.

    let strSignup = "Don't have account? SIGNUP NOW."
    let rangeSignUp = NSString(string: strSignup).range(of: "SIGNUP NOW.", options: String.CompareOptions.caseInsensitive)
    let rangeFull = NSString(string: strSignup).range(of: strSignup, options: String.CompareOptions.caseInsensitive)
    let attrStr = NSMutableAttributedString.init(string:strSignup)
    attrStr.addAttributes([NSAttributedString.Key.foregroundColor : UIColor.white,
                           NSAttributedString.Key.font : UIFont.init(name: "Helvetica", size: 17)! as Any],range: rangeFull)
    attrStr.addAttributes([NSAttributedString.Key.foregroundColor : UIColor.white,
                           NSAttributedString.Key.font : UIFont.init(name: "Helvetica", size: 20)!,
                          NSAttributedString.Key.underlineStyle: NSUnderlineStyle.thick.rawValue as Any],range: rangeSignUp) // for swift 4 -> Change thick to styleThick
    lblUnderLine.attributedText = attrStr

Output

You will need to cast or convert the values to decimal before division. Take a look at this http://msdn.microsoft.com/en-us/library/aa226054.aspx

For example

DECLARE @num1 int = 3 DECLARE @num2 int = 2

SELECT @num1/@num2

SELECT @num1/CONVERT(decimal(4,2), @num2)

The first SELECT will result in what you're seeing while the second SELECT will have the correct answer 1.500000

I have just written the following:

public static String toDelimitedString(int[] ids, String delimiter)
{
    StringBuffer strb = new StringBuffer();
    for (int id : ids)
    {
      strb.append(String.valueOf(id) + delimiter);
    }
    return strb.substring(0, strb.length() - delimiter.length());
 }

net stop <your service> && net start <your service>

No net restart, unfortunately.

If you support IE, for versions of Internet Explorer 8 and above, this:

<meta http-equiv="X-UA-Compatible" content="IE=9; IE=8; IE=7" />

Forces the browser to render as that particular version's standards. It is not supported for IE7 and below.

If you separate with semi-colon, it sets compatibility levels for different versions. For example:

<meta http-equiv="X-UA-Compatible" content="IE=7; IE=9" />

Renders IE7 and IE8 as IE7, but IE9 as IE9. It allows for different levels of backwards compatibility. In real life, though, you should only chose one of the options:

<meta http-equiv="X-UA-Compatible" content="IE=8" />

This allows for much easier testing and maintenance. Although generally the more useful version of this is using Emulate:

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE8" />

For this:

<meta http-equiv="X-UA-Compatible" content="IE=Edge" />

It forces the browser the render at whatever the most recent version's standards are.

For more information, there is plenty to read about on MSDN,

For newest version of IntelliJ, i think option has changed a bit.

Update June 2017 (from VSCode 1.14)

The ability to merge local branches has been added through PR 25731 and commit 89cd05f: accessible through the "Git: merge branch" command.
And PR 27405 added handling the diff3-style merge correctly.

Vahid's answer mention 1.17, but that September release actually added nothing regarding merge.
Only the 1.18 October one added Git conflict markers

From 1.18, with the combination of merge command (1.14) and merge markers (1.18), you truly can do local merges between branches.

Original answer 2016:

The Version Control doc does not mention merge commands, only merge status and conflict support.

Even the latest 1.3 June release does not bring anything new to the VCS front.

This is supported by issue 5770 which confirms you cannot use VS Code as a git mergetool, because:

Is this feature being included in the next iteration, by any chance?

Probably not, this is a big endeavour, since a merge UI needs to be implemented.

That leaves the actual merge to be initiated from command line only.

You should use partial views. I use the following approach:

Use a view model so you're not passing your domain models to your views:

public class EditPersonViewModel
{
    public int Id { get; set; }   // this is only used to retrieve record from Db
    public string Name { get; set; }
    public string Age { get; set; }
}

In your PersonController:

[HttpGet] // this action result returns the partial containing the modal
public ActionResult EditPerson(int id)
{  
    var viewModel = new EditPersonViewModel();
    viewModel.Id = id;
    return PartialView("_EditPersonPartial", viewModel);
}

[HttpPost] // this action takes the viewModel from the modal
public ActionResult EditPerson(EditPersonViewModel viewModel)
{
    if (ModelState.IsValid)
    {
        var toUpdate = personRepo.Find(viewModel.Id);
        toUpdate.Name = viewModel.Name;
        toUpdate.Age = viewModel.Age;
        personRepo.InsertOrUpdate(toUpdate);
        personRepo.Save();
        return View("Index");
    }
}

Next create a partial view called _EditPersonPartial. This contains the modal header, body and footer. It also contains the Ajax form. It's strongly typed and takes in our view model.

@model Namespace.ViewModels.EditPersonViewModel
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
    <h3 id="myModalLabel">Edit group member</h3>
</div>
<div>
@using (Ajax.BeginForm("EditPerson", "Person", FormMethod.Post,
                    new AjaxOptions
                    {
                        InsertionMode = InsertionMode.Replace,
                        HttpMethod = "POST",
                        UpdateTargetId = "list-of-people"
                    }))
{
    @Html.ValidationSummary()
    @Html.AntiForgeryToken()
    <div class="modal-body">
        @Html.Bootstrap().ControlGroup().TextBoxFor(x => x.Name)
        @Html.Bootstrap().ControlGroup().TextBoxFor(x => x.Age)
    </div>
    <div class="modal-footer">
        <button class="btn btn-inverse" type="submit">Save</button>
    </div>
}

Now somewhere in your application, say another partial _peoplePartial.cshtml etc:

<div>
   @foreach(var person in Model.People)
    {
        <button class="btn btn-primary edit-person" data-id="@person.PersonId">Edit</button>
    }
</div>
// this is the modal definition
<div class="modal hide fade in" id="edit-person">
    <div id="edit-person-container"></div>
</div>

    <script type="text/javascript">
    $(document).ready(function () {
        $('.edit-person').click(function () {
            var url = "/Person/EditPerson"; // the url to the controller
            var id = $(this).attr('data-id'); // the id that's given to each button in the list
            $.get(url + '/' + id, function (data) {
                $('#edit-person-container').html(data);
                $('#edit-person').modal('show');
            });
        });
     });
   </script>

I imported the new Apple WWDR Certificate that expires in 2023, but I was still getting problems and my developer certificates were showing the invalid issuer error.

In keychain access, go to View -> Show Expired Certificates, then in your login keychain highlight the expired WWDR Certificate and delete it. I also had the same expired certificate in my System keychain, so I deleted it from there too.(Important)

After deleting the expired cert from the login and System keychains, I was able to build for Distribution again.

It's a logic bomb, it keeps recreating itself and takes up all your CPU resources. It overloads your computer with too many processes and it forces it to shut down. If you make a batch file with this in it and start it you can end it using taskmgr. You have to do this pretty quickly or your computer will be too slow to do anything.

private void replaceView(View oldV,View newV){
        ViewGroup par = (ViewGroup)oldV.getParent();
        if(par == null){return;}
        int i1 = par.indexOfChild(oldV);
        par.removeViewAt(i1);
        par.addView(newV,i1);
    }

I had similar issue, I was able to solve it using -U option along with mvn command as

mvn clean install -U

This worked for me, hope it helps.

You need to provide the full path to the file:

git show 27cf8e84bb88e24ae4b4b3df2b77aab91a3735d8:full/repo/path/to/my_file.txt

Another possibility is to use bit sets, for which there is at least one package or you can use the built-in big package. In this case, basically you need to define a way to convert your object to an index.

I made a utility function iterateEnum() for iterating cases for arbitrary enum types.

Here is the example usage:

enum Suit: String {
    case Spades = "?"
    case Hearts = "?"
    case Diamonds = "?"
    case Clubs = "?"
}

for f in iterateEnum(Suit) {
    println(f.rawValue)
}

Which outputs:

?
?
?
?

But, this is only for debug or test purposes: This relies on several undocumented Swift1.1 compiler behaviors, so, use it at your own risk.

Here is the code:

func iterateEnum<T: Hashable>(_: T.Type) -> GeneratorOf<T> {
    var cast: (Int -> T)!
    switch sizeof(T) {
        case 0: return GeneratorOf(GeneratorOfOne(unsafeBitCast((), T.self)))
        case 1: cast = { unsafeBitCast(UInt8(truncatingBitPattern: $0), T.self) }
        case 2: cast = { unsafeBitCast(UInt16(truncatingBitPattern: $0), T.self) }
        case 4: cast = { unsafeBitCast(UInt32(truncatingBitPattern: $0), T.self) }
        case 8: cast = { unsafeBitCast(UInt64($0), T.self) }
        default: fatalError("cannot be here")
    }

    var i = 0
    return GeneratorOf {
        let next = cast(i)
        return next.hashValue == i++ ? next : nil
    }
}

The underlying idea is:

• Memory representation of enum, excluding enums with associated types, is just an index of cases when the count of the cases is 2...256, it's identical to UInt8, when 257...65536, it's UInt16 and so on. So, it can be unsafeBitcast from corresponding unsigned integer types.
• .hashValue of enum values is the same as the index of the case.
• .hashValue of enum values bitcasted from invalid index is 0.

Revised for Swift2 and implemented casting ideas from @Kametrixom's answer:

func iterateEnum<T: Hashable>(_: T.Type) -> AnyGenerator<T> {
    var i = 0
    return anyGenerator {
        let next = withUnsafePointer(&i) { UnsafePointer<T>($0).memory }
        return next.hashValue == i++ ? next : nil
    }
}

Revised for Swift3:

func iterateEnum<T: Hashable>(_: T.Type) -> AnyIterator<T> {
    var i = 0
    return AnyIterator {
        let next = withUnsafePointer(to: &i) {
            $0.withMemoryRebound(to: T.self, capacity: 1) { $0.pointee }
        }
        if next.hashValue != i { return nil }
        i += 1
        return next
    }
}

Revised for Swift3.0.1:

func iterateEnum<T: Hashable>(_: T.Type) -> AnyIterator<T> {
    var i = 0
    return AnyIterator {
        let next = withUnsafeBytes(of: &i) { $0.load(as: T.self) }
        if next.hashValue != i { return nil }
        i += 1
        return next
    }
}

I just had to uninstall HAXM and install it again. Then it started working again. Hope this helps someone!

Edit:

Oh wow, this was a long time ago. I have been using genymotion for a few months now, and never had any issues like that.

The following VBA code should get you started. It will copy all of the data in the original workbook to a new workbook, but it will have added 1 to each value, and all blank cells will have been ignored.

Option Explicit

Public Sub exportDataToNewBook()
    Dim rowIndex As Integer
    Dim colIndex As Integer
    Dim dataRange As Range
    Dim thisBook As Workbook
    Dim newBook As Workbook
    Dim newRow As Integer
    Dim temp

    '// set your data range here
    Set dataRange = Sheet1.Range("A1:B100")

    '// create a new workbook
    Set newBook = Excel.Workbooks.Add

    '// loop through the data in book1, one column at a time
    For colIndex = 1 To dataRange.Columns.Count
        newRow = 0
        For rowIndex = 1 To dataRange.Rows.Count
            With dataRange.Cells(rowIndex, colIndex)

            '// ignore empty cells
            If .value <> "" Then
                newRow = newRow + 1
                temp = doSomethingWith(.value)
                newBook.ActiveSheet.Cells(newRow, colIndex).value = temp
                End If

            End With
        Next rowIndex
    Next colIndex
End Sub

Private Function doSomethingWith(aValue)

    '// This is where you would compute a different value
    '// for use in the new workbook
    '// In this example, I simply add one to it.
    aValue = aValue + 1

    doSomethingWith = aValue
End Function

I dont know about XamGrid but that's what i'll do with a standard wpf DataGrid:

<DataGrid>
    <DataGrid.Columns>
        <DataGridTemplateColumn>
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding DataContext.MyProperty, RelativeSource={RelativeSource AncestorType=MyUserControl}}"/>
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
            <DataGridTemplateColumn.CellEditingTemplate>
                <DataTemplate>
                    <TextBox Text="{Binding DataContext.MyProperty, RelativeSource={RelativeSource AncestorType=MyUserControl}}"/>
                </DataTemplate>
            </DataGridTemplateColumn.CellEditingTemplate>
        </DataGridTemplateColumn>
    </DataGrid.Columns>
</DataGrid>

Since the TextBlock and the TextBox specified in the cell templates will be part of the visual tree, you can walk up and find whatever control you need.

something like so might work:

<script type="text/javascript">
$(document).ready(function(){
    var $input = $("<input name='myField' type='text'>");
    $('#section2').append($input);
});
</script>

<form>
    <div id="section1"><!-- some controls--></div>
    <div id="section2"><!-- for dynamic controls--></div>
</form>

The question I would ask is, why are you including the extra columns in your DataTable if they aren't required?

Maybe you should modify your SQL select statement so that it is looking at the specific criteria you are looking for as you are populating your DataTable.

You could also use LINQ to query your DataTable as Enumerable and create a List Object that represents only certain columns.

Other than that, hide the DataGridView Columns that you don't require.

You could also use the stringr package:

library(stringr)
str_length("foo")
[1] 3

Create an initializer for it:

# config/initializers/time_formats.rb

Add something like this to it:

Time::DATE_FORMATS[:custom_datetime] = "%d.%m.%Y"

And then use it the following way:

post.updated_at.to_s(:custom_datetime)

?? Your have to restart rails server for this to work.

Check the documentation for more information: http://api.rubyonrails.org/v5.1/classes/DateTime.html#method-i-to_formatted_s

Just need to add font-size: 0; to your element that contains text. This works well.

This is a method which will work:

import java.awt.image.BufferedImage;
import java.awt.Rectangle;
import java.awt.Color;
import java.awt.Graphics;

public BufferedImage crop(BufferedImage src, Rectangle rect)
{
    BufferedImage dest = new BufferedImage(rect.getWidth(), rect.getHeight(), BufferedImage.TYPE_ARGB_PRE);
    Graphics g = dest.getGraphics();
    g.drawImage(src, 0, 0, rect.getWidth(), rect.getHeight(), rect.getX(), rect.getY(), rect.getX() + rect.getWidth(), rect.getY() + rect.getHeight(), null);
    g.dispose();
    return dest;
}

Of course you have to make your own JComponent:

import java.awt.event.MouseListener;
import java.awt.event.MouseMotionListener;
import java.awt.image.BufferedImage;
import java.awt.Rectangle;
import java.awt.Graphics;
import javax.swing.JComponent;

public class JImageCropComponent extends JComponent implements MouseListener, MouseMotionListener
{
   private BufferedImage img;
   private int x1, y1, x2, y2;

   public JImageCropComponent(BufferedImage img)
   {
       this.img = img;
       this.addMouseListener(this);
       this.addMouseMotionListener(this);
   }

   public void setImage(BufferedImage img)
   {
       this.img = img;
   }

   public BufferedImage getImage()
   {
       return this;
   }

   @Override
   public void paintComponent(Graphics g)
   {
      g.drawImage(img, 0, 0, this);
      if (cropping)
      {
          // Paint the area we are going to crop.
          g.setColor(Color.RED);
          g.drawRect(Math.min(x1, x2), Math.min(y1, y2), Math.max(x1, x2), Math.max(y1, y2));
      }
   }

   @Override
   public void mousePressed(MouseEvent evt)
   {
       this.x1 = evt.getX();
       this.y1 = evt.getY();
   }

   @Override
   public void mouseReleased(MouseEvent evt)
   {
       this.cropping = false;
       // Now we crop the image;
       // This is the method a wrote in the other snipped
       BufferedImage cropped = crop(new Rectangle(Math.min(x1, x2), Math.min(y1, y2), Math.max(x1, x2), Math.max(y1, y2));
       // Now you have the cropped image;
       // You have to choose what you want to do with it
       this.img = cropped;
   }

   @Override
   public void mouseDragged(MouseEvent evt)
   {
       cropping = true;
       this.x2 = evt.getX();
       this.y2 = evt.getY();
   }

   //TODO: Implement the other unused methods from Mouse(Motion)Listener

}

I didn't test it. Maybe there are some mistakes (I'm not sure about all the imports).

You can put the crop(img, rect) method in this class. Hope this helps.

I added the following method to my PageBase class.

protected void Redirect(string url)
    {
        Response.Redirect(url);
    }
protected void Redirect(string url, NameValueCollection querystrings)
    {
        StringBuilder redirectUrl = new StringBuilder(url);

        if (querystrings != null)
        {
            for (int index = 0; index < querystrings.Count; index++)
            {
                if (index == 0)
                {
                    redirectUrl.Append("?");
                }

                redirectUrl.Append(querystrings.Keys[index]);
                redirectUrl.Append("=");
                redirectUrl.Append(HttpUtility.UrlEncode(querystrings[index]));

                if (index < querystrings.Count - 1)
                {
                    redirectUrl.Append("&");
                }
            }
        }

        this.Redirect(redirectUrl.ToString());
    }

To call:

NameValueCollection querystrings = new NameValueCollection();    
querystrings.Add("language", "en");
querystrings.Add("id", "134");
this.Redirect("http://www.mypage.com", querystrings);

$array = [
  'category1' => 'first category',
  'category2' => 'second category',
];
 
$new = array_map(function($key, $value) {
  return "{$key} => {$value}";
}, array_keys($array), $array);

As mentioned in numerous threads, the "standard" way of doing this is using setjmp/longjmp. I posted yet another such solution to https://github.com/psevon/exceptions-and-raii-in-c This is to my knowledge the only solution that relies on automatic cleanup of allocated resources. It implements unique and shared smartpointers, and allows intermediate functions to let exceptions pass through without catching and still have their locally allocated resources cleaned up properly.

Main purpose for Boolean is null value. Null value says, that property is undefined, for example take database nullable column.

If you really need to convert everyting from primitive boolean to wrapper Boolean, then you could use following to support old code:

Boolean set = Boolean.FALSE; //set to default value primitive value (false)
...
if (set) ...

Nothing worked for me except:

driver.set_window_size(1024, 600)
driver.maximize_window()

I found this by inspecting selenium/webdriver/remote/webdriver.py. I've never found any useful documentation, but reading the code has been marginally effective.

That should work:

>>> df = pd.DataFrame()
>>> data = pd.DataFrame({"A": range(3)})
>>> df.append(data)
   A
0  0
1  1
2  2

But the append doesn't happen in-place, so you'll have to store the output if you want it:

>>> df
Empty DataFrame
Columns: []
Index: []
>>> df = df.append(data)
>>> df
   A
0  0
1  1
2  2

In My case, I had a added async at app.js like shown below.

const App = async() => {
return(
<Text>Hello world</Text>
)
}

But it was not necessary, when testing something I had added it and it was no longer required. After removing it, as shown below, things started working.

 const App =() => {
    return(
    <Text>Hello world</Text>
    )
}

Just add 'unsigned' for the FOREIGN constraint

`FK` int(11) unsigned DEFAULT NULL,

You can also try this.

File file = new File(strDirectoy,imgname);
OutputStream fOut = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG, 85, fOut);
fOut.flush();
fOut.close();
MediaStore.Images.Media.insertImage(getContentResolver(),file.getAbsolutePath(),file.getName(),file.getName());

select <column list> into <dest. table> from <source table>;

You could do this way.

SELECT windows_release, windows_service_pack_level, 
       windows_sku, os_language_version
into   new_table_name
FROM   sys.dm_os_windows_info OPTION (RECOMPILE);

Strings, by C definition, are terminated by '\0'. You have no "C strings" in your program.

Your program reads characters (buffered till ENTER) from the standard input (the keyboard) and writes them back to the standard output (the screen). It does this no matter how many characters you type or for how long you do this.

To stop the program you have to indicate that the standard input has no more data (huh?? how can a keyboard have no more data?).

You simply press Ctrl+D (Unix) or Ctrl+Z (Windows) to pretend the file has reached its end.
Ctrl+D (or Ctrl+Z) are not really characters in the C sense of the word.

If you run your program with input redirection, the EOF is the actual end of file, not a make belief one
./a.out < source.c

After a long time suffering from it in PHPunit...

For those using namespace, which is very common with Frameworks or CMS, a good check in addition to seeing if php-xml is installed and active, is to remember to declare the DOMDocument after the namespace:

namespace YourNameSpace\YourNameSpace;

use DOMDocument; //<--- here, check this!

You don't, see below

I find this 'feature' rather annoying since I'm not trying to launch rockets to the moon, just push my damn branch. You probably do too or else you wouldn't be here!

Here is the fix: if you want it to implicitly push for the current branch regardless of if that branch exists on origin just issue this command once and you will never have to again anywhere:

git config --global push.default current

So if you make branches like this:

git checkout -b my-new-branch

and then make some commits and then do a

git push -u

to get them out to origin (being on that branch) and it will create said branch for you if it doesn't exist.

Note the -u bit makes sure they are linked if you were to pull later on from said branch. If you have no plans to pull the branch later (or are okay with another one liner if you do) -u is not necessary.

There is also a way to do this with some restrictions. This is the code from the article:

public string RelativePath(string absPath, string relTo)
    {
        string[] absDirs = absPath.Split('\\');
        string[] relDirs = relTo.Split('\\');
        // Get the shortest of the two paths 
        int len = absDirs.Length < relDirs.Length ? absDirs.Length : relDirs.Length;
        // Use to determine where in the loop we exited 
        int lastCommonRoot = -1; int index;
        // Find common root 
        for (index = 0; index < len; index++)
        {
            if (absDirs[index] == relDirs[index])
                lastCommonRoot = index;
            else break;
        }
        // If we didn't find a common prefix then throw 
        if (lastCommonRoot == -1)
        {
            throw new ArgumentException("Paths do not have a common base");
        }
        // Build up the relative path 
        StringBuilder relativePath = new StringBuilder();
        // Add on the .. 
        for (index = lastCommonRoot + 1; index < absDirs.Length; index++)
        {
            if (absDirs[index].Length > 0) relativePath.Append("..\\");
        }
        // Add on the folders 
        for (index = lastCommonRoot + 1; index < relDirs.Length - 1; index++)
        {
            relativePath.Append(relDirs[index] + "\\");
        }
        relativePath.Append(relDirs[relDirs.Length - 1]);
        return relativePath.ToString();
    }

When executing this piece of code:

string path1 = @"C:\Inetpub\wwwroot\Project1\Master\Dev\SubDir1"; 
string path2 = @"C:\Inetpub\wwwroot\Project1\Master\Dev\SubDir2\SubDirIWant";

System.Console.WriteLine (RelativePath(path1, path2));
System.Console.WriteLine (RelativePath(path2, path1));

it prints out:

..\SubDir2\SubDirIWant
..\..\SubDir1

The copy command is a SQL*Plus command (not a SQL Developer command). If you have your tnsname entries setup for SID1 and SID2 (e.g. try a tnsping), you should be able to execute your command.

Another assumption is that table1 has the same columns as the message_table (and the columns have only the following data types: CHAR, DATE, LONG, NUMBER or VARCHAR2). Also, with an insert command, you would need to be concerned about primary keys (e.g. that you are not inserting duplicate records).

I tried a variation of your command as follows in SQL*Plus (with no errors):

copy from scott/tiger@db1 to scott/tiger@db2 create new_emp using select * from emp;

After I executed the above statement, I also truncate the new_emp table and executed this command:

copy from scott/tiger@db1 to scott/tiger@db2 insert new_emp using select * from emp;

With SQL Developer, you could do the following to perform a similar approach to copying objects:

1. On the tool bar, select Tools>Database copy.

2. Identify source and destination connections with the copy options you would like.

3. For object type, select table(s).

4. Specify the specific table(s) (e.g. table1).

The copy command approach is old and its features are not being updated with the release of new data types. There are a number of more current approaches to this like Oracle's data pump (even for tables).

There is a modern API dedicated for this purpose - Broadcast Channel

It is as easy as:

var bc = new BroadcastChannel('test_channel');

bc.postMessage('This is a test message.'); /* send */

bc.onmessage = function (ev) { console.log(ev); } /* receive */

There is no need for the message to be just a DOMString, any kind of object can be sent.

Probably, apart from API cleanness, it is the main benefit of this API - no object stringification.

Currently supported only in Chrome and Firefox, but you can find a polyfill that uses localStorage.

Description and examples can be found in IEEE Std 1800-2017 § 11.5.1 "Vector bit-select and part-select addressing". First IEEE appearance is IEEE 1364-2001 (Verilog) § 4.2.1 "Vector bit-select and part-select addressing". Here is an direct example from the LRM:

logic [31: 0] a_vect;
logic [0 :31] b_vect;
logic [63: 0] dword;
integer sel;
a_vect[ 0 +: 8] // == a_vect[ 7 : 0]
a_vect[15 -: 8] // == a_vect[15 : 8]
b_vect[ 0 +: 8] // == b_vect[0 : 7]
b_vect[15 -: 8] // == b_vect[8 :15]
dword[8*sel +: 8] // variable part-select with fixed width

If sel is 0 then dword[8*(0) +: 8] == dword[7:0]
If sel is 7 then dword[8*(7) +: 8] == dword[63:56]

The value to the left always the starting index. The number to the right is the width and must be a positive constant. the + and - indicates to select the bits of a higher or lower index value then the starting index.

Assuming address is in little endian ([msb:lsb]) format, then if(address[2*pointer+:2]) is the equivalent of if({address[2*pointer+1],address[2*pointer]})

Or you could do it properly:

In your HtmlHelper Extension class:

public static MvcHtmlString FileFor<TModel, TProperty>(this HtmlHelper<TModel> helper, Expression<Func<TModel, TProperty>> expression)
    {
        return helper.FileFor(expression, null);
    }

public static MvcHtmlString FileFor<TModel, TProperty>(this HtmlHelper<TModel> helper, Expression<Func<TModel, TProperty>> expression, object htmlAttributes)
    {
        var builder = new TagBuilder("input");

        var id = helper.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldName(ExpressionHelper.GetExpressionText(expression));
        builder.GenerateId(id);
        builder.MergeAttribute("name", id);
        builder.MergeAttribute("type", "file");

        builder.MergeAttributes(new RouteValueDictionary(htmlAttributes));

        // Render tag
        return MvcHtmlString.Create(builder.ToString(TagRenderMode.SelfClosing));
    }

This line:

var id = helper.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldName(ExpressionHelper.GetExpressionText(expression));

Generates an id unique to the model, you know in lists and stuff. model[0].Name etc.

Create the correct property in the model:

public HttpPostedFileBase NewFile { get; set; }

Then you need to make sure your form will send files:

@using (Html.BeginForm("Action", "Controller", FormMethod.Post, new { enctype = "multipart/form-data" }))

Then here's your helper:

@Html.FileFor(x => x.NewFile)

IBM provide a number of tools which can be used on the sun jvm as well. Take a look at some of the projects on alphaworks, they provide a heap and thread dump analyzers

Vue allows for you to specify a default prop value and type directly, by making props an object (see: https://vuejs.org/guide/components.html#Prop-Validation):

props: {
  year: {
    default: 2016,
    type: Number
  }
}

If the wrong type is passed then it throws an error and logs it in the console, here's the fiddle:

https://jsfiddle.net/cexbqe2q/

You may want to also look into using Task instead of background workers.

The easiest way to do this is in your example is Task.Run(InitializationThread);.

There are several benefits to using tasks instead of background workers. For example, the new async/await features in .net 4.5 use Task for threading. Here is some documentation about Task https://docs.microsoft.com/en-us/dotnet/api/system.threading.tasks.task

As seen in Install crontab on CentOS, the crontab package in CentOS is vixie-cron. Hence, do install it with:

yum install vixie-cron

And then start it with:

service crond start

To make it persistent, so that it starts on boot, use:

chkconfig crond on

On CentOS 7 you need to use cronie:

yum install cronie

On CentOS 6 you can install vixie-cron, but the real package is cronie:

yum install vixie-cron

and

yum install cronie

In both cases you get the same output:

It is not clear to me what you mean by "escape an executable which is running", but ctrl-z will put a process into the background and return control to the command line. You can then use the fg command to bring the program back into the foreground.

private JSONObject uploadToServer() throws IOException, JSONException {
            String query = "https://example.com";
            String json = "{\"key\":1}";

            URL url = new URL(query);
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.setConnectTimeout(5000);
            conn.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
            conn.setDoOutput(true);
            conn.setDoInput(true);
            conn.setRequestMethod("POST");

            OutputStream os = conn.getOutputStream();
            os.write(json.getBytes("UTF-8"));
            os.close();

            // read the response
            InputStream in = new BufferedInputStream(conn.getInputStream());
            String result = org.apache.commons.io.IOUtils.toString(in, "UTF-8");
            JSONObject jsonObject = new JSONObject(result);


            in.close();
            conn.disconnect();

            return jsonObject;
    }

The formatting can be done like this (I assumed you meant HH:MM instead of HH:SS, but it's easy to change):

Time.now.strftime("%d/%m/%Y %H:%M")
#=> "14/09/2011 14:09"

Updated for the shifting:

d = DateTime.now
d.strftime("%d/%m/%Y %H:%M")
#=> "11/06/2017 18:11"
d.next_month.strftime("%d/%m/%Y %H:%M")
#=> "11/07/2017 18:11"

You need to require 'date' for this btw.

It depends on the way your page behaves. If you want this to happens asynchronously, you have to use AJAX. Try out "jQuery post()" on Google to find some tuts.

In other case, if this will happen when a user submits a form, you can send the variable in an hidden field or append ?variableName=someValue" to then end of the URL you are opening. :

http://www.somesite.com/send.php?variableName=someValue

or

http://www.somesite.com/send.php?variableName=someValue&anotherVariable=anotherValue

This way, from PHP you can access this value as:

$phpVariableName = $_POST["variableName"];

for forms using POST method or:

$phpVariableName = $_GET["variableName"];

for forms using GET method or the append to url method I've mentioned above (querystring).

The input won't have a value if it doesn't exist. Try this...

if($('.input1').val())

If you need a counter in an for-each loop you have to count yourself. There is no built in counter as far as I know.

In your client SOAP handler you need to set javax.xml.ws.security.auth.username and javax.xml.ws.security.auth.password property as follow:

public class ClientHandler implements SOAPHandler<SOAPMessageContext>{

    public boolean handleMessage(final SOAPMessageContext soapMessageContext)
    {
        final Boolean outInd = (Boolean)soapMessageContext.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
        if (outInd.booleanValue())
        {
          try 
          {
               soapMessageContext.put("javax.xml.ws.security.auth.username", <ClientUserName>);
               soapMessageContext.put("javax.xml.ws.security.auth.password", <ClientPassword>);
          } 
          catch (Exception e)
          {
               e.printStackTrace();
               return false;
          }
         }
      return true;
     }
}

LoadLibrary does not do what you think it does. It loads the DLL into the memory of the current process, but it does not magically import functions defined in it! This wouldn't be possible, as function calls are resolved by the linker at compile time while LoadLibrary is called at runtime (remember that C++ is a statically typed language).

You need a separate WinAPI function to get the address of dynamically loaded functions: GetProcAddress.

Example

#include <windows.h>
#include <iostream>

/* Define a function pointer for our imported
 * function.
 * This reads as "introduce the new type f_funci as the type: 
 *                pointer to a function returning an int and 
 *                taking no arguments.
 *
 * Make sure to use matching calling convention (__cdecl, __stdcall, ...)
 * with the exported function. __stdcall is the convention used by the WinAPI
 */
typedef int (__stdcall *f_funci)();

int main()
{
  HINSTANCE hGetProcIDDLL = LoadLibrary("C:\\Documents and Settings\\User\\Desktop\\test.dll");

  if (!hGetProcIDDLL) {
    std::cout << "could not load the dynamic library" << std::endl;
    return EXIT_FAILURE;
  }

  // resolve function address here
  f_funci funci = (f_funci)GetProcAddress(hGetProcIDDLL, "funci");
  if (!funci) {
    std::cout << "could not locate the function" << std::endl;
    return EXIT_FAILURE;
  }

  std::cout << "funci() returned " << funci() << std::endl;

  return EXIT_SUCCESS;
}

Also, you should export your function from the DLL correctly. This can be done like this:

int __declspec(dllexport) __stdcall funci() {
   // ...
}

As Lundin notes, it's good practice to free the handle to the library if you don't need them it longer. This will cause it to get unloaded if no other process still holds a handle to the same DLL.

Randomizing the array is intensive as you have to shift around a bunch of strings. Why not just randomly read from the array? In the worst case you could even create a wrapper class with a getNextString(). If you really do need to create a random array then you could do something like

for i = 0 -> i= array.length * 5
   swap two strings in random places

The *5 is arbitrary.

if one of the column is number i have experienced the oracle will think '+' as sum operator instead concatenation.

eg:

select (id + name) as one from table 1; (id is numeric) 

throws invalid number exception

in such case you can || operator which is concatenation.

select (id || name) as one from table 1;

Oxi's answer is just wrong.¹

What you want is:

var container = document.body,
element = document.getElementById('ElementID');
container.scrollTop = element.offsetTop;

Working example:

(function (){
  var i = 20, l = 20, html = '';
  while (i--){
    html += '<div id="DIV' +(l-i)+ '">DIV ' +(l-i)+ '</div>';
    html += '<a onclick="document.body.scrollTop=document.getElementById(\'DIV' +i+ '\').offsetTop">';
    html += '[ Scroll to #DIV' +i+ ' ]</a>';
    html += '<br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />';
  }
  document.write( html );
})();

Anyone else who is struggling with this, there is a very simple "inline" way to do this with jQuery:

<input type="search" placeholder="Search" value="" maxlength="256" id="q" name="q" style="width: 300px;" onChange="$('#ADSearch').attr('value', $('#q').attr('value'))"><input type="hidden" name="ADSearch" id="ADSearch" value="">

This sets the value of the hidden field as text is typed into the visible input using the onChange event. Helpful (like in my case) where you want to pass on a field value to an "Advanced Search" form and not force the user to re-type their search query.

Here is the code i made that 100% finds only the domain name, since it takes mozilla sub tlds to account. Only thing you have to check is how you make cache of that file, so you dont query mozilla every time.

For some strange reason, domains like co.uk are not in the list, so you have to make some hacking and add them manually. Its not cleanest solution but i hope it helps someone.

The server will automatically abort connections over which no message has been received for the duration equal to the receive timeout (default is 10 mins). This is a DoS mitigation to prevent clients from forcing the server to have connections open for an indefinite amount of time.

Since the server aborts the connection because it has gone idle, the client gets this exception.

You can control how long the server allows a connection to go idle before aborting it by configuring the receive timeout on the server's binding. Credit: T.R.Vishwanath - MSFT

With C#6.0 you also have a new way of formatting date when using string interpolation e.g.

$"{DateTime.Now:yyyy-MM-dd HH:mm:ss}"

Can't say its any better, but it is slightly cleaner if including the formatted DateTime in a longer string.

More about string interpolation.

//Try this if you can't use -std=c++11:-
int number=55;
char tempStr[32] = {0};
sprintf(tempStr, "%d", number);

You have to replace string line

QString line = in.readLine();

into while:

QFile file("/home/hamad/lesson11.txt");
if(!file.open(QIODevice::ReadOnly)) {
    QMessageBox::information(0, "error", file.errorString());
}

QTextStream in(&file);

while(!in.atEnd()) {
    QString line = in.readLine();    
    QStringList fields = line.split(",");    
    model->appendRow(fields);    
}

file.close();

You only have tried comma-separated and semicolon-separated CSV. If you had tried tab-separated CSV (also called TSV) you would have found the answer:

UTF-16LE with BOM (byte order mark), tab-separated

But: In a comment you mention that TSV is not an option for you (I haven't been able to find this requirement in your question though). That's a pity. It often means that you allow manual editing of TSV files, which probably is not a good idea. Visual checking of TSV files is not a problem. Furthermore editors can be set to display a special character to mark tabs.

And yes, I tried this out on Windows and Mac.

Works in Net Core 2.1

    var file = Path.Combine(Directory.GetCurrentDirectory(), "wwwroot", "email", "EmailRegister.htm");

    string SendData = System.IO.File.ReadAllText(file);

Microsoft started to address the issue in late 2015 by releasing VisualStudioUninstaller.

They abandoned the solution for a while; however work has begun again as of April 2016.

There has finally been an official release for this uninstaller in April 2016 which is described as being "designed to cleanup/scorch all Preview/RC/RTM releases of Visual Studio 2013, Visual Studio 2015 and Visual Studio vNext".

It is possible of course, use -l: instead of -l. For example -l:libXYZ.a to link with libXYZ.a. Notice the lib written out, as opposed to -lXYZ which would auto expand to libXYZ.

Starting with SQL Server 2012, you could use TRY_PARSE or TRY_CONVERT.

SELECT TRY_PARSE(MyVarcharCol as int)

SELECT TRY_CONVERT(int, MyVarcharCol)

This is solution, which does not enables shell using mv.

from subprocess import Popen, PIPE, STDOUT

source = "path/to/current/file.foo", 
destination = "path/to/new/destination/for/file.foo"

p = Popen(["mv", "-v", source, destination], stdout=PIPE, stderr=STDOUT)
output, _ = p.communicate()
output = output.strip().decode("utf-8")
if p.returncode:
    print(f"E: {output}")
else:
    print(output)

Everyone else has explained why throwing destructors are terrible... what can you do about it? If you're doing an operation that may fail, create a separate public method that performs cleanup and can throw arbitrary exceptions. In most cases, users will ignore that. If users want to monitor the success/failure of the cleanup, they can simply call the explicit cleanup routine.

For example:

class TempFile {
public:
    TempFile(); // throws if the file couldn't be created
    ~TempFile() throw(); // does nothing if close() was already called; never throws
    void close(); // throws if the file couldn't be deleted (e.g. file is open by another process)
    // the rest of the class omitted...
};

Historically, the first extensions used for C++ were .c and .h, exactly like for C. This caused practical problems, especially the .c which didn't allow build systems to easily differentiate C++ and C files.

Unix, on which C++ has been developed, has case sensitive file systems. So some used .C for C++ files. Other used .c++, .cc and .cxx. .C and .c++ have the problem that they aren't available on other file systems and their use quickly dropped. DOS and Windows C++ compilers tended to use .cpp, and some of them make the choice difficult, if not impossible, to configure. Portability consideration made that choice the most common, even outside MS-Windows.

Headers have used the corresponding .H, .h++, .hh, .hxx and .hpp. But unlike the main files, .h remains to this day a popular choice for C++ even with the disadvantage that it doesn't allow to know if the header can be included in C context or not. Standard headers now have no extension at all.

Additionally, some are using .ii, .ixx, .ipp, .inl for headers providing inline definitions and .txx, .tpp and .tpl for template definitions. Those are either included in the headers providing the definition, or manually in the contexts where they are needed.

Compilers and tools usually don't care about what extensions are used, but using an extension that they associate with C++ prevents the need to track out how to configure them so they correctly recognize the language used.

2017 edit: the experimental module support of Visual Studio recognize .ixx as a default extension for module interfaces, clang++ is recognizing .c++m, .cppm and .cxxm for the same purpose.

I've just have a similar problem, a simple solution is to just use:

.click()

Any other solution will work if you refresh radio after calling function.

In Html:

<div [style.maxHeight]="maxHeightForScrollContainer + 'px'">
</div>

In Ts

this.maxHeightForScrollContainer = 200 //your custom maxheight

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

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

This snippet elucidates the difference:

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

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

As others have noted, it is usually preferable to specify a minimum logging level to log that level and any others more severe than it. It seems like you are just thinking about the logging levels backwards.

However, if you want more fine-grained control over logging individual levels, you can tell log4net to log only one or more specific levels using the following syntax:

<filter type="log4net.Filter.LevelMatchFilter">
  <levelToMatch value="WARN"/>
</filter>

Or to exclude a specific logging level by adding a "deny" node to the filter.

You can stack multiple filters together to specify multiple levels. For instance, if you wanted only WARN and FATAL levels. If the levels you wanted were consecutive, then the LevelRangeFilter is more appropriate.

Reference Doc: log4net.Filter.LevelMatchFilter

If the other answers haven't given you enough information, hopefully this will help you get what you want out of log4net.

My current BKM for this is

... | xargs -n1 -I % perl -e 'system("echo 1 %"); system("echo 2 %");'

It is unfortunate that this uses perl, which is less likely to be installed than bash; but it handles more input that the accepted answer. (I welcome a ubiquitous version that does not rely on perl.)

@KeithThompson's suggestion of

 ... | xargs -I % sh -c 'command1; command2; ...'

is great - unless you have the shell comment character # in your input, in which case part of the first command and all of the second command will be truncated.

Hashes # can be quite common, if the input is derived from a filesystem listing, such as ls or find, and your editor creates temporary files with # in their name.

Example of the problem:

$ bash 1366 $>  /bin/ls | cat
#Makefile#
#README#
Makefile
README

Oops, here is the problem:

$ bash 1367 $>  ls | xargs -n1 -I % sh -i -c 'echo 1 %; echo 2 %'
1
1
1
1 Makefile
2 Makefile
1 README
2 README

Ahh, that's better:

$ bash 1368 $>  ls | xargs -n1 -I % perl -e 'system("echo 1 %"); system("echo 2 %");'
1 #Makefile#
2 #Makefile#
1 #README#
2 #README#
1 Makefile
2 Makefile
1 README
2 README
$ bash 1369 $>  

<div><p>some unnecessary content</p></div>

div{
    border: 1px solid red;
    width: 40%;
    padding: 40%;
    box-sizing: border-box;
    position: relative;
}
p{
    position: absolute;
    top: 0;
    left: 0;
}

For this to work i think you need to define the padding to ex. top? like this:

<div><p>some unnecessary content</p></div>

div{
    border: 1px solid red;
    width: 40%;
    padding-top: 40%;
    box-sizing: border-box;
    position: relative;
}
p{
    position: absolute;
    top: 0;
    left: 0;
}

anyways, thats how i got it to work, since with just padding all arround it would not be a square.

Because Stage is required, all one-to-many relationships where Stage is involved will have cascading delete enabled by default. It means, if you delete a Stage entity

• the delete will cascade directly to Side
• the delete will cascade directly to Card and because Card and Side have a required one-to-many relationship with cascading delete enabled by default again it will then cascade from Card to Side

So, you have two cascading delete paths from Stage to Side - which causes the exception.

You must either make the Stage optional in at least one of the entities (i.e. remove the [Required] attribute from the Stage properties) or disable cascading delete with Fluent API (not possible with data annotations):

modelBuilder.Entity<Card>()
    .HasRequired(c => c.Stage)
    .WithMany()
    .WillCascadeOnDelete(false);

modelBuilder.Entity<Side>()
    .HasRequired(s => s.Stage)
    .WithMany()
    .WillCascadeOnDelete(false);

For some reason Andrew method of creating the checkbox by hand didn't work for me using Mvc 5. Instead I used this

@Html.CheckBox("checkResp")

to create a checkbox that would play nice with the controller.

Both John Conde's and ryeballar's answers are correct and will work.

If you want to get too geeky:

• John's has the downside that it has to make two decisions per $digest loop (it has to decide whether to add/remove center and it has to decide whether to add/remove left), when clearly only one is needed.

• Ryeballar's relies on the ternary operator which is probably going to be removed at some point (because the view should not contain any logic). (We can't be sure it will indeed be removed and it probably won't be any time soon, but if there is a more "safe" solution, why not ?)

So, you can do the following as an alternative:

ng-class="{true:'center',false:'left'}[page.isSelected(1)]"

Array into table. Array into div. JSON into table. JSON into div.

All are nicely handle this class. Click here to get a class

How to use it?

Just get and object

$obj = new Arrayinto();

Create an array you want to convert

$obj->array_object = array("AAA" => "1111",
                  "BBB" => "2222",
                  "CCC" => array("CCC-1" => "123",
                                 "CCC-2" => array("CCC-2222-A" => "CA2",
                                                  "CCC-2222=B" => "CB2"
                                                 )
                                )

                 );

If you want to convert Array into table. Call this.

$result = $obj->process_table();

If you want to convert Array into div. Call this.

$result = $obj->process_div();

Let suppose if you have a JSON

$obj->json_string = '{
            "AAA":"11111",
            "BBB":"22222",
            "CCC":[
                    {
                        "CCC-1":"123"
                    },
                    {
                        "CCC-2":"456"
                    }
                  ] 
         }
        ';

You can convert into table/div like this

$result = $obj->process_json('div');

OR

$result = $obj->process_json('table');

I've seen your code in web.php as follows: Route::post('/edit/{id}','ProjectController@update');

Step 1: remove the {id} random parameter so it would be like this: Route::post('/edit','ProjectController@update');

Step 2: Then remove the @method('PUT') in your form, so let's say we'll just plainly use the POST method

Then how can I pass the ID to my method?

Step 1: make an input field in your form with the hidden attribute for example

<input type="hidden" value="{{$project->id}}" name="id">

Step 2: in your update method in your controller, fetch that ID for example:

$id = $request->input('id');

then you may not use it to find which project to edit

$project = Project::find($id)
//OR
$project = Project::where('id',$id);

In the hypothetical situation where you could perform a potentially expensive non-const operation on an object, returning by const-value prevents you from accidentally calling this operation on a temporary. Imagine that + returned a non-const value, and you could write:

(a + b).expensive();

In the age of C++11, however, it is strongly advised to return values as non-const so that you can take full advantage of rvalue references, which only make sense on non-constant rvalues.

In summary, there is a rationale for this practice, but it is essentially obsolete.

If you want a code that is readable by all programmers (c++, java, and others) use the original old form instead of cryptographic new features

atp::ta::DataDrawArrayInfo* ddai;
for(size_t i = 0; i < m_dataDraw->m_dataDrawArrayInfoList.size(); i++) {
    ddai = m_dataDraw->m_dataDrawArrayInfoList[i];
    //...
}
