Programs & Examples On #Touches

You can use json_decode(Your variable Name):

json_decode($result)

I was getting value from Model.where a column has value like this way

{"dayList":[
            {"day":[1,2,3,4],"time":[{"in_time":"10:00"},{"late_time":"15:00"},{"out_time":"16:15"}]
             },
             {"day":[5,6,7],"time":[{"in_time":"10:00"},{"late_time":"15:00"},{"out_time":"16:15"}]}
           ]
}

so access this value form model. you have to use this code.

$dayTimeListObject = json_decode($settingAttendance->bio_attendance_day_time,1);

 foreach ( $dayTimeListObject['dayList'] as $dayListArr)
 {
     foreach ( $dayListArr['day'] as $dayIndex)
     {
         if( $dayIndex == Date('w',strtotime('2020-02-11')))
         {
             $dayTimeList= $dayListArr['time'];
         }
     }
 }

 return $dayTimeList[2]['out_time'] ;

You can also define caste in your Model file.

 protected $casts = [
    'your-column-name' => 'json'
  ];

so after this no need of this line .

$dayTimeListObject = json_decode($settingAttendance->bio_attendance_day_time,1);

you can directly access this code.

$settingAttendance->bio_attendance_day_time

Any chance that you changed the name of your table view from "tableView" to "myTableView" at some point?

Tested this code using XCode 8 and Swift 3

To Add Custom View to SuperView use:

self.view.addSubview(myView)

To Remove Custom View from Superview use:

self.view.willRemoveSubview(myView)

Please remove e.preventDefault(), because event.cancelable of touchmove is false. So you can't call this method.

Another approach using the new Swift 2 syntax is to use guard and nest it all in one conditional.

guard let touch = object.AnyObject() as? UITouch, let picker = touch.view as? UIPickerView else {
    return //Do Nothing
}
//Do something with picker

For people looking at a simpler solution, I think you can just have this one line of code in onStart()

  getWindow().getDecorView().setSystemUiVisibility(
            View.SYSTEM_UI_FLAG_HIDE_NAVIGATION|
            View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);

It's called Immersive mode. You may look at the official documentation for other possibilities.

Data content is so variable, I think the best form is to define it as "ObjectNode" and next create his own class to parse:

Finally:

private ObjectNode data;

Try to get an idea about what a first responder is in iOS view hierarchy. When your textfield becomes active(or first responder) when you touch inside it (or pass it the messasge becomeFirstResponder programmatically), it presents the keyboard. So to remove your textfield from being the first responder, you should pass the message resignFirstResponder to it there.

[textField resignFirstResponder];

And to hide the keyboard on its return button, you should implement its delegate method textFieldShouldReturn: and pass the resignFirstResponder message.

- (BOOL)textFieldShouldReturn:(UITextField *)textField{
    [textField resignFirstResponder];
    return YES;
}

I too had this problem. But apparently there is an issue of the order of method calls. You must call:

[self.picker selectRow:2 inComponent:0 animated:YES];

after calling

[self.view addSubview:self.picker];

I sometimes use a bit of a trick to do just that. I put an invisible focus holder somewhere on the top of the layout. It would be e.g. like this

 <EditText android:id="@id/editInvisibleFocusHolder"
          style="@style/InvisibleFocusHolder"/>

with this style

<style name="InvisibleFocusHolder">
    <item name="android:layout_width">0dp</item>
    <item name="android:layout_height">0dp</item>
    <item name="android:focusable">true</item>
    <item name="android:focusableInTouchMode">true</item>
    <item name="android:inputType">none</item>
</style>

and then in onResume I would call

    editInvisibleFocusHolder.setInputType(InputType.TYPE_NULL);
    editInvisibleFocusHolder.requestFocus();

That works nicely for me from 1.6 up to 4.x

//----firstly you have to alloc the double and single tap gesture-------//

UITapGestureRecognizer* doubleTap = [[UITapGestureRecognizer alloc] initWithTarget : self action : @selector (handleDoubleTap:)];

UITapGestureRecognizer* singleTap = [[UITapGestureRecognizer alloc] initWithTarget : self action : @selector (handleSingleTap:)];

[singleTap requireGestureRecognizerToFail : doubleTap];
[doubleTap setDelaysTouchesBegan : YES];
[singleTap setDelaysTouchesBegan : YES];

//-----------------------number of tap----------------//

[doubleTap setNumberOfTapsRequired : 2];
[singleTap setNumberOfTapsRequired : 1];

//------- add double tap and single tap gesture on the view or button--------//

[self.view addGestureRecognizer : doubleTap];
[self.view addGestureRecognizer : singleTap];

jQuery 'fixes up' events to account for browser differences. When it does so, you can always access the 'native' event with event.originalEvent (see the Special Properties subheading on this page).

Did you try InputMethodManager.SHOW_IMPLICIT in first window.

and for hiding in second window use InputMethodManager.HIDE_IMPLICIT_ONLY

EDIT :

If its still not working then probably you are putting it at the wrong place. Override onFinishInflate() and show/hide there.

@override
public void onFinishInflate() {
     /* code to show keyboard on startup */
    InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.showSoftInput(mUserNameEdit, InputMethodManager.SHOW_IMPLICIT);
}

The Swift 2 version:

// start detecting pan gesture
let panGestureRecognizer = UIPanGestureRecognizer(target: self, action: #selector(TTAltimeterDetailViewController.panGestureDetected(_:)))
panGestureRecognizer.minimumNumberOfTouches = 1
self.chartOverlayView.addGestureRecognizer(panGestureRecognizer)

func panGestureDetected(panGestureRecognizer: UIPanGestureRecognizer) {
    print("pan gesture recognized")
}

This code compiles and works for me. It converts a double to a string using the calls you tried.

public class TestDouble {

    public static void main(String[] args) {
        double total = 44;
        String total2 = Double.toString(total);

        System.out.println("Double is " + total2);
    }
}

I am puzzled by your seeing the NumberFormatException. Look at the stack trace. I'm guessing you have other code that you are not showing in your example that is causing that exception to be thrown.

How about this: I know this is an old post. It might help someone :)

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {  
    NSArray *subviews = [self.view subviews];
    for (id objects in subviews) {
        if ([objects isKindOfClass:[UITextField class]]) {
            UITextField *theTextField = objects;
            if ([objects isFirstResponder]) {
                [theTextField resignFirstResponder];
            }
        } 
    }
}

Simply define two properties of parent of that EditText as :

android:clickable="true"
android:focusableInTouchMode="true"

So when user will touch outside of EditText area, focus will be removed because focus will be transferred to parent view.

Seems quite simple these days. This is the Swift version.

let tap = UITapGestureRecognizer(target: self, action: #selector(viewTapped))
    view.addGestureRecognizer(tap)

@objc func viewTapped(recognizer: UIGestureRecognizer)
{
    //Do what you need to do!
}

If you don't want your program to look like an iPhone program that is force fitted into Android, aim for a more native look and feel and do something similar to Gingerbread:

There is a simpler approach, based on iPhone same issue. Simply override the background's layout on touch event, where the edit text is contained. Just use this code in the activity's OnCreate (login_fondo is the root layout):

    final LinearLayout llLogin = (LinearLayout)findViewById(R.id.login_fondo);
    llLogin.setOnTouchListener(
            new OnTouchListener()
            {
                @Override
                public boolean onTouch(View view, MotionEvent ev) {
                    InputMethodManager imm = (InputMethodManager) mActivity.getSystemService(
                            android.content.Context.INPUT_METHOD_SERVICE);
                    imm.hideSoftInputFromWindow(mActivity.getCurrentFocus().getWindowToken(), 0);
                    return false;
                }
            });

Even this works.

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" android:drawable="@color/dim_orange_btn_pressed" />
    <item android:state_focused="true" android:drawable="@color/dim_orange_btn_pressed" />
    <item android:drawable="@android:color/white" />
</selector>

I added the android:drawable attribute to each item, and their values are colors.

By the way, why do they say that color is one of the attributes of selector? They don't write that android:drawable is required.

Color State List Resource

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item
        android:color="hex_color"
        android:state_pressed=["true" | "false"]
        android:state_focused=["true" | "false"]
        android:state_selected=["true" | "false"]
        android:state_checkable=["true" | "false"]
        android:state_checked=["true" | "false"]
        android:state_enabled=["true" | "false"]
        android:state_window_focused=["true" | "false"] />
</selector>

From ListView: Disable Focus Highlight,

when you set your ListAdapter use the following code

ListAdapter adapter = new SimpleCursorAdapter(MyList, Layout, c, 
                new String[] { "Name", "Score" }, to) 
{ 
    public boolean areAllItemsEnabled() 
    { 
        return false; 
    } 
    public boolean isEnabled(int position) 
    { 
        return false; 
    } 
}; 

This will override the BaseAdapter class. It also cancels the white border between cells.

in android i did this using kotlin:

private fun angleBetweenPoints(a: PointF, b: PointF): Double {
        val deltaY = abs(b.y - a.y)
        val deltaX = abs(b.x - a.x)
        return Math.toDegrees(atan2(deltaY.toDouble(), deltaX.toDouble()))
    }

Here is my solution for behavior like in @followben answer, but without loss with slow start (when dy is 0)

@property (assign, nonatomic) BOOL isFinding;
@property (assign, nonatomic) CGFloat previousOffset;

- (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView {
    self.isFinding = YES;
}
- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
    if (self.isFinding) {
        if (self.previousOffset == 0) {
            self.previousOffset = self.tableView.contentOffset.y;

        } else {
            CGFloat diff = self.tableView.contentOffset.y - self.previousOffset;
            if (diff != 0) {
                self.previousOffset = 0;
                self.isFinding = NO;

                if (diff > 0) {
                    // moved up
                } else {
                    // moved down
                }
            }
        }
    }
}

override func setSelected(selected: Bool, animated: Bool) {
    // Configure the view for the selected state

    super.setSelected(selected, animated: animated)
    let selView = UIView()

    selView.backgroundColor = UIColor( red: 5/255, green: 159/255, blue:223/255, alpha: 1.0 )
    self.selectedBackgroundView = selView
}

webView.scrollView.scrollEnabled=NO; webView.scrollView.bounces=NO;

I had this issue for a day until I found the real resolution. Instead of trying to force unmount an smb share that is hung, mount the share with the "soft" option. If a process attempts to connect to the share that is not available it will stop trying after a certain amount of time.

soft Make the mount soft. Fail file system calls after a number of seconds.

mount -t smbfs -o soft //username@server/share /users/username/smb/share

stat /users/username/smb/share/file
stat: /users/username/smb/share/file: stat: Operation timed out

May not be a real answer to your question but it is a solution to the problem

Timer.Elapsed expects method of specific signature (with arguments object and EventArgs). If you want to use your PlayMusicEvent method with additional argument evaluated during event registration, you can use lambda expression as an adapter:

myTimer.Elapsed += new ElapsedEventHandler((sender, e) => PlayMusicEvent(sender, e, musicNote));

Edit: you can also use shorter version:

myTimer.Elapsed += (sender, e) => PlayMusicEvent(sender, e, musicNote);

CentOs 6.5+ & PHP 5.6:

sudo yum install php56-gd

service httpd restart

This one doesn't alter the original newer branch, and gives you the opportunity to make further modifications before final commit.

git checkout new -b tmp
git merge -s ours old -m 'irrelevant'
git checkout old
git merge --squash tmp
git branch -D tmp
#do any other stuff you want
git add -A; git commit -m 'foo' #commit (or however you like)

• Under Server Administration on the Home window select the server instance you want to restore database to (Create New Server Instance if doing it first time).
• Click on Manage Import/Export
• Click on Data Import/Restore on the left side of the screen.
• Select Import from Self-Contained File radio button (right side of screen)
• Select the path of .sql
• Click Start Import button at the right bottom corner of window.

Hope it helps.

---Edited answer---

Regarding selection of the schema. MySQL Workbench (5.2.47 CE Rev1039) does not yet support exporting to the user defined schema. It will create only the schema for which you exported the .sql... In 5.2.47 we see "New" target schema. But it does not work. I use MySQL Administrator (the old pre-Oracle MySQL Admin beauty) for my work for backup/restore. You can still download it from Googled trustable sources (search MySQL Administrator 1.2.17).

You could have probably concluded your question after the second paragraph, rather than calling people "insane" simply because they have a different viewpoint than you do and otherwise trying to mock professionals who may have a very good reason for feeling the way that they do.

As to your question, while there are certainly situations where a cursor may be called for, in my experience developers decide that a cursor "must" be used FAR more often than is actually the case. The chance of someone erring on the side of too much use of cursors vs. not using them when they should is MUCH higher in my opinion.

If you want to add a scroll bar using jquery the following will work. If your div had a id of 'mydiv' you could us the following jquery id selector with css property:

jQuery('#mydiv').css("overflow-y", "scroll");

Here is my solution using jQuery

<script type="text/javascript">
    $('#mtoogle').toggle(
        function () {
            document.getElementById('playTune').pause();
        },
        function () {
            document.getElementById('playTune').play();
        }
    );
</script>

Your welcome page is set as That Servlet . So all css , images path should be given relative to that servlet DIR . which is a bad idea ! why do you need the servlet as a home page ? set .jsp as index page and redirect to any page from there ?

are you trying to populate any fields from db is that why you are using servlet ?

A simple and efficient way, inspired from the implementation of transform in SeqLike.scala

    var i = 0
    xs foreach { el =>
      println("String #" + i + " is " + xs(i))
      i += 1
    }

Try:

select replace(convert(varchar, getdate(), 111),'/','-');

You do not need the line:

import { SigninComponent, RegisterComponent } from './auth/auth.module';

in your app.component.ts as you already included the AuthModule in your app.module.ts. AutModule import is sufficient to use your component in the app.

The error that you get is a TypeScript error, not a Angular one, and it is correct in stating that there is no exported member, as it searches for a valid EC6 syntax for export, not angular module export. This line would thus work in your app.component.ts:

import { SigninComponent } from './auth/components/signin.component';

There is one simple way by which we can check if file exists or not in S3 bucket. We donot need to use exception for this

sesssion = boto3.Session(aws_access_key_id, aws_secret_access_key)
s3 = session.client('s3')

object_name = 'filename'
bucket = 'bucketname'
obj_status = s3.list_objects(Bucket = bucket, Prefix = object_name)
if obj_status.get('Contents'):
    print("File exists")
else:
    print("File does not exists")

In Ubuntu 14.04.2 LTS:

1. Go to Software Center and remove "IDLE(using Python-2.7)".

2. Install "IDLE(using Python-3.4)".

Try again. This step worked for me.

I use one Factory module that contains one (or more) constructor per class which calls the Init member of each class.

For example a Point class:

Class Point
Private X, Y
Sub Init(X, Y)
  Me.X = X
  Me.Y = Y
End Sub

A Line class

Class Line
Private P1, P2
Sub Init(Optional P1, Optional P2, Optional X1, Optional X2, Optional Y1, Optional Y2)
  If P1 Is Nothing Then
    Set Me.P1 = NewPoint(X1, Y1)
    Set Me.P2 = NewPoint(X2, Y2)
  Else
    Set Me.P1 = P1
    Set Me.P2 = P2
  End If
End Sub

And a Factory module:

Module Factory
Function NewPoint(X, Y)
  Set NewPoint = New Point
  NewPoint.Init X, Y
End Function

Function NewLine(Optional P1, Optional P2, Optional X1, Optional X2, Optional Y1, Optional Y2)
  Set NewLine = New Line
  NewLine.Init P1, P2, X1, Y1, X2, Y2
End Function

Function NewLinePt(P1, P2)
  Set NewLinePt = New Line
  NewLinePt.Init P1:=P1, P2:=P2
End Function

Function NewLineXY(X1, Y1, X2, Y2)
  Set NewLineXY = New Line
  NewLineXY.Init X1:=X1, Y1:=Y1, X2:=X2, Y2:=Y2
End Function

One nice aspect of this approach is that makes it easy to use the factory functions inside expressions. For example it is possible to do something like:

D = Distance(NewPoint(10, 10), NewPoint(20, 20)

or:

D = NewPoint(10, 10).Distance(NewPoint(20, 20))

It's clean: the factory does very little and it does it consistently across all objects, just the creation and one Init call on each creator.

And it's fairly object oriented: the Init functions are defined inside the objects.

EDIT

I forgot to add that this allows me to create static methods. For example I can do something like (after making the parameters optional):

NewLine.DeleteAllLinesShorterThan 10

Unfortunately a new instance of the object is created every time, so any static variable will be lost after the execution. The collection of lines and any other static variable used in this pseudo-static method must be defined in a module.

I had the Same problem when connecting to a Socket and I came up with the below solution ,It works Fine for me. `

private bool CheckConnectivityForProxyHost(string hostName, int port)
       {
           if (string.IsNullOrEmpty(hostName))
               return false;

           bool isUp = false;

               IPAddress ip = null;
               if (testSocket != null && NetworkingCollaboratorBase.GetResolvedConnecionIPAddress(hostName, out ip))//Use a method to resolve your IP

InputStream is used for reading, OutputStream for writing. They are connected as decorators to one another such that you can read/write all different types of data from all different types of sources.

For example, you can write primitive data to a file:

File file = new File("C:/text.bin");
file.createNewFile();
DataOutputStream stream = new DataOutputStream(new FileOutputStream(file));
stream.writeBoolean(true);
stream.writeInt(1234);
stream.close();

To read the written contents:

File file = new File("C:/text.bin");
DataInputStream stream = new DataInputStream(new FileInputStream(file));
boolean isTrue = stream.readBoolean();
int value = stream.readInt();
stream.close();
System.out.printlin(isTrue + " " + value);

You can use other types of streams to enhance the reading/writing. For example, you can introduce a buffer for efficiency:

DataInputStream stream = new DataInputStream(
    new BufferedInputStream(new FileInputStream(file)));

You can write other data such as objects:

MyClass myObject = new MyClass(); // MyClass have to implement Serializable
ObjectOutputStream stream = new ObjectOutputStream(
    new FileOutputStream("C:/text.obj"));
stream.writeObject(myObject);
stream.close();

You can read from other different input sources:

byte[] test = new byte[] {0, 0, 1, 0, 0, 0, 1, 1, 8, 9};
DataInputStream stream = new DataInputStream(new ByteArrayInputStream(test));
int value0 = stream.readInt();
int value1 = stream.readInt();
byte value2 = stream.readByte();
byte value3 = stream.readByte();
stream.close();
System.out.println(value0 + " " + value1 + " " + value2 + " " + value3);

For most input streams there is an output stream, also. You can define your own streams to reading/writing special things and there are complex streams for reading complex things (for example there are Streams for reading/writing ZIP format).

Anything that is static is in the class level. You don't have to create instance to access static fields/method. Static variable will be created once when class is loaded.

Instance variables are the variable associated with the object which means that instance variables are created for each object you create. All objects will have separate copy of instance variable for themselves.

In your case, when you declared it as static final, that is only one copy of variable. If you change it from multiple instance, the same variable would be updated (however, you have final variable so it cannot be updated).

In second case, the final int a is also constant , however it is created every time you create an instance of the class where that variable is declared.

Have a look on this Java tutorial for better understanding ,

I guess something like this would do the job.

var option = document.createElement("option");
option.text = "Text";
option.value = "myvalue";
var select = document.getElementById("daySelect");
select.appendChild(option);

There is cppcheck which is supported also by Hudson via the plugin of the same name.

you have to check your pip package to be updated to the latest version in your pycharm and then install numpy package. in settings -> project:progLangComp -> Project Interpreter there is a table of packages and their current version (just labelled as Version) and their latest version (labelled as Latest). Pip current version number should be the same as latest version. If you see a blue arrow in front of pip, you have to update it to the latest then trying to install numpy or any other packages that you couldn't install, for me it was pandas which I wanted to install.

Partial solution: for a single string column tmp = df['A1'].fillna(''); isEmpty = tmp=='' gives boolean Series of True where there are empty strings or NaN values.

If you are using jupiter and none of the answers work, consider verifying it is setup correctly:

test {
    useJUnitPlatform()
    outputs.upToDateWhen { false }
}

dependencies {
    testImplementation 'org.junit.jupiter:junit-jupiter-api:5.7.0'
    testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine:5.7.0'
}

And then try the accepted answers

The default in the php.ini for the session.gc_maxlifetime directive (the "gc" is for garbage collection) is 1440 seconds or 24 minutes. See the Session Runtime Configuation page in the manual:

http://www.php.net/manual/en/session.configuration.php

You can change this constant in the php.ini or .httpd.conf files if you have access to them, or in the local .htaccess file on your web site. To set the timeout to one hour using the .htaccess method, add this line to the .htaccess file in the root directory of the site:

php_value session.gc_maxlifetime "3600"

Be careful if you are on a shared host or if you host more than one site where you have not changed the default. The default session location is the /tmp directory, and the garbage collection routine will run every 24 minutes for these other sites (and wipe out your sessions in the process, regardless of how long they should be kept). See the note on the manual page or this site for a better explanation.

The answer to this is to move your sessions to another directory using session.save_path. This also helps prevent bad guys from hijacking your visitors' sessions from the default /tmp directory.

Consider the case statement as well which is compatible with most sh-based shells:

case $str in
/*)
    echo 1
    ;;
*)
    echo 0
    ;;
esac

# here database details      
mysql_connect('hostname', 'username', 'password');
mysql_select_db('database-name');

$sql = "SELECT username FROM userregistraton";
$result = mysql_query($sql);

echo "<select name='username'>";
while ($row = mysql_fetch_array($result)) {
    echo "<option value='" . $row['username'] ."'>" . $row['username'] ."</option>";
}
echo "</select>";

# here username is the column of my table(userregistration)
# it works perfectly

You have this bad but usefull technic:

$var = json_decode(json_encode([]), FALSE);

Based on SourceSimian's response; this worked on Windows domain user accounts. Note that the Username does not have domain included,

task setHttpProxyFromEnv {
    def map = ['HTTP_PROXY': 'http', 'HTTPS_PROXY': 'https']
    for (e in System.getenv()) {
        def key = e.key.toUpperCase()
        if (key in map) {
            def base = map[key]
            def url = e.value.toURL()
            println " - systemProp.${base}.proxy=${url.host}:${url.port}"
            System.setProperty("${base}.proxyHost", url.host.toString())
            System.setProperty("${base}.proxyPort", url.port.toString())
            System.setProperty("${base}.proxyUser", "Username")
            System.setProperty("${base}.proxyPassword", "Password")
        }
    }
}
build.dependsOn setHttpProxyFromEnv

Unfortunately, there isn't a TryParse() equivalent. If you create a new instance of a System.Guid and pass the string value in, you can catch the three possible exceptions it would throw if it is invalid.

Those are:

• ArgumentNullException
• FormatException
• OverflowException

I have seen some implementations where you can do a regex on the string prior to creating the instance, if you are just trying to validate it and not create it.

var checkboxes = document.getElementsByName('location[]');
var vals = "";
for (var i=0, n=checkboxes.length;i<n;i++) 
{
    if (checkboxes[i].checked) 
    {
        vals += ","+checkboxes[i].value;
    }
}
if (vals) vals = vals.substring(1);

This is impossible to answer and has been brought up many many times before. Do a search, read those threads, then pick the framework you and your team have experience with.

I like to create an easily visible object out of it like this.

Object.keys(localStorage).reduce(function(obj, str) { 
    obj[str] = localStorage.getItem(str); 
    return obj
}, {});

I do a similar thing with cookies as well.

document.cookie.split(';').reduce(function(obj, str){ 
    var s = str.split('='); 
    obj[s[0].trim()] = s[1];
    return obj;
}, {});

This should work fine.

var now  = "04/09/2013 15:00:00";
var then = "02/09/2013 14:20:30";

var ms = moment(now,"DD/MM/YYYY HH:mm:ss").diff(moment(then,"DD/MM/YYYY HH:mm:ss"));
var d = moment.duration(ms);

console.log(d.days() + ':' + d.hours() + ':' + d.minutes() + ':' + d.seconds());

Incase of arrays, the base address (i.e. address of the array) is the address of the 1st element in the array. Also the array name acts as a pointer.

Consider a row of houses (each is an element in the array). To identify the row, you only need the 1st house address.You know each house is followed by the next (sequential).Getting the address of the 1st house, will also give you the address of the row.

Incase of string literals(character arrays defined at declaration), they are automatically appended by \0.

printf prints using the format specifier and the address provided. Since, you use %s it prints from the 1st address (incrementing the pointer using arithmetic) until '\0'

Type info variables to list "All global and static variable names".

Type info locals to list "Local variables of current stack frame" (names and values), including static variables in that function.

Type info args to list "Arguments of the current stack frame" (names and values).

You can choose two ways:

1) By code in the client

public static void Main()
{
    Uri baseAddress = new Uri("http://localhost/MyServer/MyService");

    try
    {
        ServiceHost serviceHost = new ServiceHost(typeof(CalculatorService));

        WSHttpBinding binding = new WSHttpBinding();
        binding.OpenTimeout = new TimeSpan(0, 10, 0);
        binding.CloseTimeout = new TimeSpan(0, 10, 0);
        binding.SendTimeout = new TimeSpan(0, 10, 0);
        binding.ReceiveTimeout = new TimeSpan(0, 10, 0);

        serviceHost.AddServiceEndpoint("ICalculator", binding, baseAddress);
        serviceHost.Open();

        // The service can now be accessed.
        Console.WriteLine("The service is ready.");
        Console.WriteLine("Press <ENTER> to terminate service.");
        Console.WriteLine();
        Console.ReadLine();

    }
    catch (CommunicationException ex)
    {
        // Handle exception ...
    }
}

2)By WebConfig in a web server

<configuration>
  <system.serviceModel>
    <bindings>
      <wsHttpBinding>
        <binding openTimeout="00:10:00" 
                 closeTimeout="00:10:00" 
                 sendTimeout="00:10:00" 
                 receiveTimeout="00:10:00">
        </binding>
      </wsHttpBinding>
    </bindings>
  </system.serviceModel>

The best way using a button is

<input type= 'button' onclick='javascript:history.back();return false;' value='Back'>

Python 3:

The official csv documentation recommends opening the file with newline='' on all platforms to disable universal newlines translation:

with open('output.csv', 'w', newline='', encoding='utf-8') as f:
    writer = csv.writer(f)
    ...

The CSV writer terminates each line with the lineterminator of the dialect, which is \r\n for the default excel dialect on all platforms.

Python 2:

On Windows, always open your files in binary mode ("rb" or "wb"), before passing them to csv.reader or csv.writer.

Although the file is a text file, CSV is regarded a binary format by the libraries involved, with \r\n separating records. If that separator is written in text mode, the Python runtime replaces the \n with \r\n, hence the \r\r\n observed in the file.

See this previous answer.

For portability, try this:

#ifdef _WIN32
#include <conio.h>
#else
#include <stdio.h>
#define clrscr() printf("\e[1;1H\e[2J")
#endif

Then simply call clrscr(). On Windows, it will use conio.h's clrscr(), and on Linux, it will use ANSI escape codes.

If you really want to do it "properly", you can eliminate the middlemen (conio, printf, etc.) and do it with just the low-level system tools (prepare for a massive code-dump):

#ifdef _WIN32
#define WIN32_LEAN_AND_MEAN
#include <windows.h>

void ClearScreen()
{
  HANDLE                     hStdOut;
  CONSOLE_SCREEN_BUFFER_INFO csbi;
  DWORD                      count;
  DWORD                      cellCount;
  COORD                      homeCoords = { 0, 0 };

  hStdOut = GetStdHandle( STD_OUTPUT_HANDLE );
  if (hStdOut == INVALID_HANDLE_VALUE) return;

  /* Get the number of cells in the current buffer */
  if (!GetConsoleScreenBufferInfo( hStdOut, &csbi )) return;
  cellCount = csbi.dwSize.X *csbi.dwSize.Y;

  /* Fill the entire buffer with spaces */
  if (!FillConsoleOutputCharacter(
    hStdOut,
    (TCHAR) ' ',
    cellCount,
    homeCoords,
    &count
    )) return;

  /* Fill the entire buffer with the current colors and attributes */
  if (!FillConsoleOutputAttribute(
    hStdOut,
    csbi.wAttributes,
    cellCount,
    homeCoords,
    &count
    )) return;

  /* Move the cursor home */
  SetConsoleCursorPosition( hStdOut, homeCoords );
}

#else // !_WIN32
#include <unistd.h>
#include <term.h>

void ClearScreen()
{
  if (!cur_term)
  {
     int result;
     setupterm( NULL, STDOUT_FILENO, &result );
     if (result <= 0) return;
  }

   putp( tigetstr( "clear" ) );
}
#endif

Regardless of the OS the below command should work:

java -cp "MyJar.jar;lib/*" com.mainClass

Always use quotes and please take attention that lib/*.jar will not work.

You could use UNION to combine two joins:

SELECT Table1.PhoneNumber1 as PhoneNumber, Table2.SomeOtherField as OtherField
  FROM Table1
  JOIN Table2
    ON Table1.PhoneNumber1 = Table2.PhoneNumber
 UNION
SELECT Table1.PhoneNumber2 as PhoneNumber, Table2.SomeOtherField as OtherField
  FROM Table1
  JOIN Table2
    ON Table1.PhoneNumber2 = Table2.PhoneNumber

Standard Python dictionaries are inherently unordered, so what you're asking to do doesn't really make sense.

If you really, really know what you're doing, use

value_at_index = dic.values()[index]

Bear in mind that adding or removing an element can potentially change the index of every other element.

Use this function:

$(".price").each(function(){
total_price += parseInt($(this).val());
});

99.9% of the time the error ORA-65096: invalid common user or role name means you are logged into the CDB when you should be logged into a PDB.

But if you insist on creating users the wrong way, follow the steps below.

DANGER

Setting undocumented parameters like this (as indicated by the leading underscore) should only be done under the direction of Oracle Support. Changing such parameters without such guidance may invalidate your support contract. So do this at your own risk.

Specifically, if you set "_ORACLE_SCRIPT"=true, some data dictionary changes will be made with the column ORACLE_MAINTAINED set to 'Y'. Those users and objects will be incorrectly excluded from some DBA scripts. And they may be incorrectly included in some system scripts.

If you are OK with the above risks, and don't want to create common users the correct way, use the below answer.

Before creating the user run:

alter session set "_ORACLE_SCRIPT"=true;  

I found the answer here

You can get the value attribute directly since you know it's an <input> element, but your current usage of .val() is already the current one.

For the above, just use .value on the DOM element directly, like this:

$(document).ready(function(){
  $("#txt_name").keyup(function(){
    alert(this.value);
  });
});

Once I found what format it was looking for in the connection string, it worked just fine like this with Oracle.ManagedDataAccess. Without having to mess around with anything separately.

DATA SOURCE=DSDSDS:1521/ORCL;

An array is a variable, so in that case mapfile will work

mapfile y <<'z'
abc'asdf"
$(dont-execute-this)
foo"bar"''
z

Then you can print like this

printf %s "${y[@]}"

For me this works perfectly:

let font = UIFont.systemFont(ofSize: 12, weight: .medium)
let text = "text"
let attString = NSMutableAttributedString(string: "exemple text :)")

attString.addAttributes([.font: font], range:(attString.string as NSString).range(of: text))

label.attributedText = attString

The most straigh forward way I found using VisualStudio 2019 to debug an external library to which you are referencing in NuGet, is by taking the following steps:

1. Tools > Options > Debugging > General > Untick 'Enable Just My Code'

2. Go to Assembly Explorer > Open from NuGet Packages Cache

3. Type the NuGet package name you want to debug in the search field & click 'OK'

4. From the Assembly Explorer, right-click on the assembly imported and select 'Generate Pdb'

5. Select a custom path where you want to save the .PDB file and the framework you want this to be generated for

   

6. Copy the .PDB file from the folder generated to your Debug folder and you can now set breakpoints on this assembly's library code

Yes, ReSharper does this. Right click on your solution and selection "Find Code Issues". One of the results is "Unused Symbols". This will show you classes, methods, etc., that aren't used.

Sure, being in master branch all you need to do is:

git merge <commit-id>

where commit-id is hash of the last commit from newbranch that you want to get in your master branch.

You can find out more about any git command by doing git help <command>. It that case it's git help merge. And docs are saying that the last argument for merge command is <commit>..., so you can pass reference to any commit or even multiple commits. Though, I never did the latter myself.

The solution is to put an N in front of both the type and the SQL string to indicate it is a double-byte character string:

DECLARE @SQL NVARCHAR(100) 
SET @SQL = N'SELECT TOP 1 * FROM sys.tables' 
EXECUTE sp_executesql @SQL

You can also use openssl to accomplish the same thing:

$ openssl pkcs12 -nokeys -info \
    -in </path/to/file.pfx> \
    -passin pass:<pfx's password>

There is a straight forward clean solution available. Use the wholeTextFiles() method. This will take a directory and forms a key value pair. The returned RDD will be a pair RDD. Find below the description from Spark docs:

SparkContext.wholeTextFiles lets you read a directory containing multiple small text files, and returns each of them as (filename, content) pairs. This is in contrast with textFile, which would return one record per line in each file

A few key changes to Daniel Galasko's answer fixed all my problems. Unfortunately, I don't have enough reputation to comment directly (yet).

In step 1, when using Auto Layout, simply add a single parent UIView to the cell. EVERYTHING inside the cell must be a subview of the parent. That answered all of my problems. While Xcode adds this for UITableViewCells automatically, it doesn't (but it should) for UICollectionViewCells. According to the docs:

To configure the appearance of your cell, add the views needed to present the data item’s content as subviews to the view in the contentView property. Do not directly add subviews to the cell itself.

Then skip step 3 entirely. It isn't needed.

As mentioned in the comments to the question, the JDBC-ODBC Bridge is - as the name indicates - only a mechanism for the JDBC layer to "talk to" the ODBC layer. Even if you had a JDBC-ODBC Bridge on your Mac you would also need to have

• an implementation of ODBC itself, and
• an appropriate ODBC driver for the target database (ACE/Jet, a.k.a. "Access")

So, for most people, using JDBC-ODBC Bridge technology to manipulate ACE/Jet ("Access") databases is really a practical option only under Windows. It is also important to note that the JDBC-ODBC Bridge will be has been removed in Java 8 (ref: here).

There are other ways of manipulating ACE/Jet databases from Java, such as UCanAccess and Jackcess. Both of these are pure Java implementations so they work on non-Windows platforms. For details on how to use UCanAccess see

Manipulating an Access database from Java without ODBC

ArrayDeque is probably the fastest object-based queue in the JDK; Trove has the TIntQueue interface, but I don't know where its implementations live.

If you want to ignore the certificate all together then take a look at the answer here: Ignore self-signed ssl cert using Jersey Client

Although this will make your app vulnerable to man-in-the-middle attacks.

Or, try adding the cert to your java store as a trusted cert. This site may be helpful. http://blog.icodejava.com/tag/get-public-key-of-ssl-certificate-in-java/

Here's another thread showing how to add a cert to your store. Java SSL connect, add server cert to keystore programmatically

The key is:

KeyStore.Entry newEntry = new KeyStore.TrustedCertificateEntry(someCert);
ks.setEntry("someAlias", newEntry, null);

Another alternative is to use a lambda:

ent.bind("<Return>", (lambda event: name_of_function()))

Full code:

from tkinter import *
from tkinter.messagebox import showinfo

def reply(name):
    showinfo(title="Reply", message = "Hello %s!" % name)


top = Tk()
top.title("Echo")
top.iconbitmap("Iconshock-Folder-Gallery.ico")

Label(top, text="Enter your name:").pack(side=TOP)
ent = Entry(top)
ent.bind("<Return>", (lambda event: reply(ent.get())))
ent.pack(side=TOP)
btn = Button(top,text="Submit", command=(lambda: reply(ent.get())))
btn.pack(side=LEFT)

top.mainloop()

As you can see, creating a lambda function with an unused variable "event" solves the problem.

If you use React this should work:

<a href="#" onClick={()=>window.open("https://...")}</a>

An issue with the answer from Michal Foksa is that it adds the query parameters first, and then expands the path variables. If query parameter contains parenthesis, e.g. {foobar}, this will cause an exception.

The safe way is to expand the path variables first, and then add the query parameters:

String url = "http://test.com/Services/rest/{id}/Identifier";
Map<String, String> params = new HashMap<String, String>();
params.put("id", "1234");
URI uri = UriComponentsBuilder.fromUriString(url)
        .buildAndExpand(params)
        .toUri();
uri = UriComponentsBuilder
        .fromUri(uri)
        .queryParam("name", "myName")
        .build()
        .toUri();
restTemplate.exchange(uri , HttpMethod.PUT, requestEntity, class_p);

I strongly recommend taking a look at Vuex, it is made for globally accessible data in Vue.

If you only need a few base variables that will never be modified, I would use ES6 imports:

// config.js
export default {
   hostname: 'myhostname'
}

// .vue file
import config from 'config.js'

console.log(config.hostname)

You could also import a json file in the same way, which can be edited by people without code knowledge or imported into SASS.

import java.text.SimpleDateFormat;
import java.util.Date;
public class Main {
public static void main(String[] args) throws Exception{
    String time1 = "12:00:00";
    String time2 = "12:01:00";
    SimpleDateFormat format = new SimpleDateFormat("HH:mm:ss");
    Date date1 = format.parse(time1);
    Date date2 = format.parse(time2);
    long difference = date2.getTime() - date1.getTime();
    System.out.println(difference/1000);
}}

throws exception handles parsing exceptions

If I've understood your problem correctly, there are two possible problems here:

• resultset is null - I assume that this can't be the case as if it was you'd get an exception in your while loop and nothing would be output.
• The second problem is that resultset.getString(i++) will get columns 1,2,3 and so on from each subsequent row.

I think that the second point is probably your problem here.

Lets say you only had 1 row returned, as follows:

Col 1, Col 2, Col 3 
A    ,     B,     C

Your code as it stands would only get A - it wouldn't get the rest of the columns.

I suggest you change your code as follows:

ResultSet resultset = ...;
ArrayList<String> arrayList = new ArrayList<String>(); 
while (resultset.next()) {                      
    int i = 1;
    while(i <= numberOfColumns) {
        arrayList.add(resultset.getString(i++));
    }
    System.out.println(resultset.getString("Col 1"));
    System.out.println(resultset.getString("Col 2"));
    System.out.println(resultset.getString("Col 3"));                    
    System.out.println(resultset.getString("Col n"));
}

Edit:

To get the number of columns:

ResultSetMetaData metadata = resultset.getMetaData();
int numberOfColumns = metadata.getColumnCount();

I only want to cover second point of the question that is related to performance, because no body else has covered this. Select Into is a lot more faster than insert into, when it comes to tables with large datasets. I prefer select into when I have to read a very large table. insert into for a table with 10 million rows may take hours while select into will do this in minutes, and as for as losing indexes on new table is concerned you can recreate the indexes by query and can still save a lot more time when compared to insert into.

Starting with C++ 11 you can use proper lambdas. See the other answers for more details.

    public:
         static void a() { printf("I'm in a!\n"); }
    };

    dummy::a();
    dummy::a();
}

Try this, works in Ruby:

DateTime.now.to_time.utc

A minor modification like below worked for me when using it from within perl and system() call:

sftp {user}@{host} <<< $'put {local_file_path} {remote_file_path}'

You can easy change collation in Microsoft SQL Server Management studio.

• right click table -> design.
• choose your column, scroll down i column properties to Collation.
• Set your sort preference by check "Case Sensitive"

This works:

''.join(('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e'))

It will produce:

'abcdgxre'

You can also use a delimiter like a comma to produce:

'a,b,c,d,g,x,r,e'

By using:

','.join(('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e'))

SELECT * FROM  mysql.general_log  WHERE command_type ='Query' LIMIT total;

First, you should disable selinux, edit file /etc/sysconfig/selinux so it looks like this:

SELINUX=disabled
SELINUXTYPE=targeted

Save file and restart system.

Then you can add the new rule to iptables:

iptables -A INPUT -m state --state NEW -p tcp --dport 8080 -j ACCEPT

and restart iptables with /etc/init.d/iptables restart

If it doesn't work you should check other network settings.

There are two separate things here:

1. object lifetime
2. storage duration

For example:

{
    vector<MyObject> v;
    // do some stuff, push some objects onto v
    v.clear(); // 1
    // maybe do some more stuff
} // 2

At 1, you clear v: this destroys all the objects it was storing. Each gets its destructor called, if your wrote one, and anything owned by that MyObject is now released. However, vector v has the right to keep the raw storage around in case you want it later.

If you decide to push some more things into it between 1 and 2, this saves time as it can reuse the old memory.

At 2, the vector v goes out of scope: any objects you pushed into it since 1 will be destroyed (as if you'd explicitly called clear again), but now the underlying storage is also released (v won't be around to reuse it any more).

If I change the example so v becomes a pointer to a dynamically-allocated vector, you need to explicitly delete it, as the pointer going out of scope at 2 doesn't do that for you. It's better to use something like std::unique_ptr in that case, but if you don't and v is leaked, the storage it allocated will be leaked as well. As above, you need to make sure v is deleted, and calling clear isn't sufficient.

How PHP handles sessions is quite confusing for beginners to understand. This might help them by giving an overview of how sessions work: how sessions work(custom-session-handlers)

Short and effective:

DateFormat.getDateTimeInstance().format(new Date(myMillisValue))

Seems to be identical just in case that SQL server will not try to read data which is not required for the query, the optimizer is clever enough

It can have sense when join on complex query (i.e which have joings, groupings etc itself) then, yes, it is better to specify required fields.

But there is one more point. If the query is simple there is no difference but EVERY extra action even which is supposed to improve performance makes optimizer works harder and optimizer can fail to get the best plan in time and will run not optimal query. So extras select can be a such action which can even decrease performance

This is more an art than a science. The Mongo Documentation on Schemas is a good reference, but here are some things to consider:

• Put as much in as possible

  The joy of a Document database is that it eliminates lots of Joins. Your first instinct should be to place as much in a single document as you can. Because MongoDB documents have structure, and because you can efficiently query within that structure (this means that you can take the part of the document that you need, so document size shouldn't worry you much) there is no immediate need to normalize data like you would in SQL. In particular any data that is not useful apart from its parent document should be part of the same document.

• Separate data that can be referred to from multiple places into its own collection.

  This is not so much a "storage space" issue as it is a "data consistency" issue. If many records will refer to the same data it is more efficient and less error prone to update a single record and keep references to it in other places.

• Document size considerations

  MongoDB imposes a 4MB (16MB with 1.8) size limit on a single document. In a world of GB of data this sounds small, but it is also 30 thousand tweets or 250 typical Stack Overflow answers or 20 flicker photos. On the other hand, this is far more information than one might want to present at one time on a typical web page. First consider what will make your queries easier. In many cases concern about document sizes will be premature optimization.

• Complex data structures:

  MongoDB can store arbitrary deep nested data structures, but cannot search them efficiently. If your data forms a tree, forest or graph, you effectively need to store each node and its edges in a separate document. (Note that there are data stores specifically designed for this type of data that one should consider as well)

  It has also been pointed out than it is impossible to return a subset of elements in a document. If you need to pick-and-choose a few bits of each document, it will be easier to separate them out.

• Data Consistency

  MongoDB makes a trade off between efficiency and consistency. The rule is changes to a single document are always atomic, while updates to multiple documents should never be assumed to be atomic. There is also no way to "lock" a record on the server (you can build this into the client's logic using for example a "lock" field). When you design your schema consider how you will keep your data consistent. Generally, the more that you keep in a document the better.

For what you are describing, I would embed the comments, and give each comment an id field with an ObjectID. The ObjectID has a time stamp embedded in it so you can use that instead of created at if you like.

This should work.

int i = 1;
foreach (ListViewItem lvi in listView.Items) {
    ...
    if(++i == 50) break;
}

Thought I would supply a Swift Solution

import UIKit

class TextField: UITextField {
    let inset: CGFloat = 10

    // placeholder position
    override func textRectForBounds(bounds: CGRect) -> CGRect {
        return CGRectInset(bounds , inset , inset)
    }

    // text position
    override func editingRectForBounds(bounds: CGRect) -> CGRect {
        return CGRectInset(bounds , inset , inset)
    }

    override func placeholderRectForBounds(bounds: CGRect) -> CGRect {
        return CGRectInset(bounds, inset, inset) 
    }
}

Swift 3+

import UIKit

class TextField: UITextField {
    let inset: CGFloat = 10

    // placeholder position
    override func textRect(forBounds: CGRect) -> CGRect {
        return forBounds.insetBy(dx: self.inset , dy: self.inset)
    }

    // text position
    override func editingRect(forBounds: CGRect) -> CGRect {
        return forBounds.insetBy(dx: self.inset , dy: self.inset)
    }

    override func placeholderRect(forBounds: CGRect) -> CGRect {
        return forBounds.insetBy(dx: self.inset, dy: self.inset)
    }

Import paths are relative to your $GOPATH and $GOROOT environment variables. For example, with the following $GOPATH:

GOPATH=/home/me/go

Packages located in /home/me/go/src/lib/common and /home/me/go/src/lib/routers are imported respectively as:

import (
    "lib/common"
    "lib/routers"
)

fibo = f.fibo references the class itself. You probably wanted fibo = f.fibo() (note the parentheses) to make an instance of the class, after which fibo.f() should succeed correctly.

f.fibo.f() fails because you are essentially calling f(self, a=0) without supplying self; self is "bound" automatically when you have an instance of the class.

I had a problem where I had to round up only and these answers didnt work for how I had to have my code run so I used a different method. The INT function rounds towards negative (4.2 goes to 4, -4.2 goes to -5) Therefore, I changed my function to negative, applied the INT function, then returned it to positive simply by multiplying it by -1 before and after

Count = -1 * (int(-1 * x))

Python really tries hard to intelligently set sys.path. How it is set can get really complicated. The following guide is a watered-down, somewhat-incomplete, somewhat-wrong, but hopefully-useful guide for the rank-and-file python programmer of what happens when python figures out what to use as the initial values of sys.path, sys.executable, sys.exec_prefix, and sys.prefix on a normal python installation.

First, python does its level best to figure out its actual physical location on the filesystem based on what the operating system tells it. If the OS just says "python" is running, it finds itself in $PATH. It resolves any symbolic links. Once it has done this, the path of the executable that it finds is used as the value for sys.executable, no ifs, ands, or buts.

Next, it determines the initial values for sys.exec_prefix and sys.prefix.

If there is a file called pyvenv.cfg in the same directory as sys.executable or one directory up, python looks at it. Different OSes do different things with this file.

One of the values in this config file that python looks for is the configuration option home = <DIRECTORY>. Python will use this directory instead of the directory containing sys.executable when it dynamically sets the initial value of sys.prefix later. If the applocal = true setting appears in the pyvenv.cfg file on Windows, but not the home = <DIRECTORY> setting, then sys.prefix will be set to the directory containing sys.executable.

Next, the PYTHONHOME environment variable is examined. On Linux and Mac, sys.prefix and sys.exec_prefix are set to the PYTHONHOME environment variable, if it exists, superseding any home = <DIRECTORY> setting in pyvenv.cfg. On Windows, sys.prefix and sys.exec_prefix is set to the PYTHONHOME environment variable, if it exists, unless a home = <DIRECTORY> setting is present in pyvenv.cfg, which is used instead.

Otherwise, these sys.prefix and sys.exec_prefix are found by walking backwards from the location of sys.executable, or the home directory given by pyvenv.cfg if any.

If the file lib/python<version>/dyn-load is found in that directory or any of its parent directories, that directory is set to be to be sys.exec_prefix on Linux or Mac. If the file lib/python<version>/os.py is is found in the directory or any of its subdirectories, that directory is set to be sys.prefix on Linux, Mac, and Windows, with sys.exec_prefix set to the same value as sys.prefix on Windows. This entire step is skipped on Windows if applocal = true is set. Either the directory of sys.executable is used or, if home is set in pyvenv.cfg, that is used instead for the initial value of sys.prefix.

If it can't find these "landmark" files or sys.prefix hasn't been found yet, then python sets sys.prefix to a "fallback" value. Linux and Mac, for example, use pre-compiled defaults as the values of sys.prefix and sys.exec_prefix. Windows waits until sys.path is fully figured out to set a fallback value for sys.prefix.

Then, (what you've all been waiting for,) python determines the initial values that are to be contained in sys.path.

1. The directory of the script which python is executing is added to sys.path. On Windows, this is always the empty string, which tells python to use the full path where the script is located instead.
2. The contents of PYTHONPATH environment variable, if set, is added to sys.path, unless you're on Windows and applocal is set to true in pyvenv.cfg.
3. The zip file path, which is <prefix>/lib/python35.zip on Linux/Mac and os.path.join(os.dirname(sys.executable), "python.zip") on Windows, is added to sys.path.
4. If on Windows and no applocal = true was set in pyvenv.cfg, then the contents of the subkeys of the registry key HK_CURRENT_USER\Software\Python\PythonCore\<DLLVersion>\PythonPath\ are added, if any.
5. If on Windows and no applocal = true was set in pyvenv.cfg, and sys.prefix could not be found, then the core contents of the of the registry key HK_CURRENT_USER\Software\Python\PythonCore\<DLLVersion>\PythonPath\ is added, if it exists;
6. If on Windows and no applocal = true was set in pyvenv.cfg, then the contents of the subkeys of the registry key HK_LOCAL_MACHINE\Software\Python\PythonCore\<DLLVersion>\PythonPath\ are added, if any.
7. If on Windows and no applocal = true was set in pyvenv.cfg, and sys.prefix could not be found, then the core contents of the of the registry key HK_CURRENT_USER\Software\Python\PythonCore\<DLLVersion>\PythonPath\ is added, if it exists;
8. If on Windows, and PYTHONPATH was not set, the prefix was not found, and no registry keys were present, then the relative compile-time value of PYTHONPATH is added; otherwise, this step is ignored.
9. Paths in the compile-time macro PYTHONPATH are added relative to the dynamically-found sys.prefix.
10. On Mac and Linux, the value of sys.exec_prefix is added. On Windows, the directory which was used (or would have been used) to search dynamically for sys.prefix is added.

At this stage on Windows, if no prefix was found, then python will try to determine it by searching all the directories in sys.path for the landmark files, as it tried to do with the directory of sys.executable previously, until it finds something. If it doesn't, sys.prefix is left blank.

Finally, after all this, Python loads the site module, which adds stuff yet further to sys.path:

It starts by constructing up to four directories from a head and a tail part. For the head part, it uses sys.prefix and sys.exec_prefix; empty heads are skipped. For the tail part, it uses the empty string and then lib/site-packages (on Windows) or lib/pythonX.Y/site-packages and then lib/site-python (on Unix and Macintosh). For each of the distinct head-tail combinations, it sees if it refers to an existing directory, and if so, adds it to sys.path and also inspects the newly added path for configuration files.

There are two flavors of table valued functions. One that is just a select statement and one that can have more rows than just a select statement.

This can not have a variable:

create function Func() returns table
as
return
select 10 as ColName

You have to do like this instead:

create function Func()
returns @T table(ColName int)
as
begin
  declare @Var int
  set @Var = 10
  insert into @T(ColName) values (@Var)
  return
end

To see local changes compare to your current branch

git diff .

To see local changed compare to any other existing branch

git diff <branch-name> .

To see changes of a particular file

git diff <branch-name> -- <file-path>

Make sure you run git fetch at the beginning.

You'll get converting errors with:

cmd.CommandText = "SELECT COUNT(*) FROM table_name";
Int32 count = (Int32) cmd.ExecuteScalar();

Use instead:

string stm = "SELECT COUNT(*) FROM table_name WHERE id="+id+";";
MySqlCommand cmd = new MySqlCommand(stm, conn);
Int32 count = Convert.ToInt32(cmd.ExecuteScalar());
if(count > 0){
    found = true; 
} else {
    found = false; 
}

It works only if the frame contains page from the same domain (does not violate same-origin policy)

See this:

var iframe = $('#your_iframe').contents();

iframe.find('your_clicable_item').click(function(event){
   console.log('work fine');
});

You can also just search on sites like Tucows and CNET, they have it there too.

For anyone using Koa and koa-passport:

Know that the key for the user set in the serializeUser method (often a unique id for that user) will be stored in:

this.session.passport.user

When you set in done(null, user) in deserializeUser where 'user' is some user object from your database:

this.req.user OR this.passport.user

for some reason this.user Koa context never gets set when you call done(null, user) in your deserializeUser method.

So you can write your own middleware after the call to app.use(passport.session()) to put it in this.user like so:

app.use(function * setUserInContext (next) {
  this.user = this.req.user
  yield next
})

If you're unclear on how serializeUser and deserializeUser work, just hit me up on twitter. @yvanscher

The below is less efficient, but I use this logic. This is valid only if you have two digits after decimal point.

double val;

if (temp.Text.Split('.').Length > 1)
{
    val = double.Parse(temp.Text.Split('.')[0]);

    if (temp.Text.Split('.')[1].Length == 1)
        val += (0.1 * double.Parse(temp.Text.Split('.')[1]));
    else
        val += (0.01 * double.Parse(temp.Text.Split('.')[1]));
}
else
    val = double.Parse(RR(temp.Text));

Python 3 has a different and simpler syntax for calling parent method.

If Foo class inherits from Bar, then from Bar.__init__ can be invoked from Foo via super().__init__():

class Foo(Bar):

    def __init__(self, *args, **kwargs):
        # invoke Bar.__init__
        super().__init__(*args, **kwargs)

stringArray.ToList().Contains(stringToCheck)

If the texts has different sizes and they must be underlined this is the solution:

<table>
  <tr>
    <td class='left'>January</td>
    <td class='right'>2014</td>
  </tr>
</table>

css:

table{
    width: 100%;
    border-bottom: 2px solid black;
    /*this is the size of the small text's baseline over part  (˜25px*3/4)*/
    line-height: 19.5px; 
}
table td{
    vertical-align: baseline;
}
.left{
    font-family: Arial;
    font-size: 40px;
    text-align: left;

}
.right{
    font-size: 25px;
    text-align: right;
}

This is the complete answer to my question. I had originally marked @Colin Williams' answer as the correct answer, as it helped me get to the complete solution. A community member, @Slipp D. Thompson edited my question, after about 2.5 years of me having asked it, and told me I was abusing SO's Q & A format. He also told me to separately post this as the answer. So here's the complete answer that solved my problem:

@Colin Williams, thank you! Your answer and the article you linked out to gave me a lead to try something with CSS.

So, I was using translate3d before. It produced unwanted results. Basically, it would chop off and NOT RENDER elements that were offscreen, until I interacted with them. So, basically, in landscape orientation, half of my site that was offscreen was not being shown. This is a iPad web app, owing to which I was in a fix.

Applying translate3d to relatively positioned elements solved the problem for those elements, but other elements stopped rendering, once offscreen. The elements that I couldn't interact with (artwork) would never render again, unless I reloaded the page.

The complete solution:

*:not(html) {
    -webkit-transform: translate3d(0, 0, 0);
}

Now, although this might not be the most "efficient" solution, it was the only one that works. Mobile Safari does not render the elements that are offscreen, or sometimes renders erratically, when using -webkit-overflow-scrolling: touch. Unless a translate3d is applied to all other elements that might go offscreen owing to that scroll, those elements will be chopped off after scrolling.

So, thanks again, and hope this helps some other lost soul. This surely helped me big time!

You can retrieve the email address from the logged in user's profile. Here is the code snippet

<?php

    $facebook = new Facebook(array(
      'appId'  => $initMe["appId"],
      'secret' => $initMe["appSecret"],
    ));

    $facebook->setAccessToken($initMe["accessToken"]);
    $user = $facebook->getUser();

    if ($user) {
        $user_profile = $facebook->api('/me');
        print_r($user_profile["email"]);
    }
?>

This is probably the best way, since it’s reliable and works on old browsers:

function indexOfMax(arr) {
    if (arr.length === 0) {
        return -1;
    }

    var max = arr[0];
    var maxIndex = 0;

    for (var i = 1; i < arr.length; i++) {
        if (arr[i] > max) {
            maxIndex = i;
            max = arr[i];
        }
    }

    return maxIndex;
}

There’s also this one-liner:

let i = arr.indexOf(Math.max(...arr));

It performs twice as many comparisons as necessary and will throw a RangeError on large arrays, though. I’d stick to the function.

eq is used to compare integers use equal '=' instead , example:

if [ 'AAA' = 'ABC' ];
then 
    echo "the same" 
else 
    echo "not the same"
fi

good luck

I have had to use code like this to provide functions to allocate memory to a pointer passed in and return its size because my company "object" to me using the STL

 int iSizeOfArray(int* &piArray) {
    piArray = new int[iNumberOfElements];
    ...
    return iNumberOfElements;
 }

It is not nice, but the pointer must be passed by reference (or use double pointer). If not, memory is allocated to a local copy of the pointer if it is passed by value which results in a memory leak.

As Tyler points out, there's no way to do what you require "directly and reliably", since a given FD may correspond to 0 filenames (in various cases) or > 1 (multiple "hard links" is how the latter situation is generally described). If you do still need the functionality with all the limitations (on speed AND on the possibility of getting 0, 2, ... results rather than 1), here's how you can do it: first, fstat the FD -- this tells you, in the resulting struct stat, what device the file lives on, how many hard links it has, whether it's a special file, etc. This may already answer your question -- e.g. if 0 hard links you will KNOW there is in fact no corresponding filename on disk.

If the stats give you hope, then you have to "walk the tree" of directories on the relevant device until you find all the hard links (or just the first one, if you don't need more than one and any one will do). For that purpose, you use readdir (and opendir &c of course) recursively opening subdirectories until you find in a struct dirent thus received the same inode number you had in the original struct stat (at which time if you want the whole path, rather than just the name, you'll need to walk the chain of directories backwards to reconstruct it).

If this general approach is acceptable, but you need more detailed C code, let us know, it won't be hard to write (though I'd rather not write it if it's useless, i.e. you cannot withstand the inevitably slow performance or the possibility of getting != 1 result for the purposes of your application;-).

So the way I would solve this problem is to make sure the two datetimes are in the right timezone.

I can see that you are using datetime.now() which will return the systems current time, with no tzinfo set.

tzinfo is the information attached to a datetime to let it know what timezone it is in. If you are using naive datetime you need to be consistent through out your system. I would highly recommend only using datetime.utcnow()

seeing as somewhere your are creating datetime that have tzinfo associated with them, what you need to do is make sure those are localized (has tzinfo associated) to the correct timezone.

Take a look at Delorean, it makes dealing with this sort of thing much easier.

I just resolved the same problem.

Dependency Walker is misleading in this case and caused me to lose time. So, the list of "missing" DLL files from the first post is not helpful, and you can probably ignore it.

The solution is to find which references your project is calling and check if they are really installed on the server.

@Ben Brammer, it is not important which three .ocx files are missing, because they are missing only for Leo T Abraham's project. Your project probably calls other DLL files.

In my case, it was not three .ocx files, but missing MySQL connector DLL file. After installing of MySQL Connector for .NET on server, the problem disappeared.

So, in short, the solution is: check if all your project references are there.

I put my initials and a dash (at-) as the first three characters of the branch name for this exact reason:

git branch -D `git branch --list 'at-*'`

Sometimes it is possible to solve it in the model like this: Suppose you have 3 boolean properties OptionA, OptionB, OptionC.

XAML:

<RadioButton IsChecked="{Binding OptionA}"/>
<RadioButton IsChecked="{Binding OptionB}"/>
<RadioButton IsChecked="{Binding OptionC}"/>

CODE:

private bool _optionA;
public bool OptionA
{
    get { return _optionA; }
    set
    {
        _optionA = value;
        if( _optionA )
        {
             this.OptionB= false;
             this.OptionC = false;
        }
    }
}

private bool _optionB;
public bool OptionB

    set
    {

}

You get the idea. Not the cleanest thing, but easy.

This is a dynamic solution which works with all value types including objects :

class Session extends Map {
  set(id, value) {
    if (typeof value === 'object') value = JSON.stringify(value);
    sessionStorage.setItem(id, value);
  }

  get(id) {
    const value = sessionStorage.getItem(id);
    try {
      return JSON.parse(value);
    } catch (e) {
      return value;
    }
  }
}

Then :

const session = new Session();

session.set('name', {first: 'Ahmed', last : 'Toumi'});
session.get('name');

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

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

Hope this saves you some typing

The option that I tend to use, mostly because it's simple and I don't have to think, is using Write-Output as below. Write-Output will put an EOL marker in the string for you and you can simply output the finished string.

Write-Output $stringThatNeedsEOLMarker | Out-File -FilePath PathToFile -Append

Alternatively, you could also just build the entire string using Write-Output and then push the finished string into Out-File.

String currency = "135.69";
System.out.println(new BigDecimal(currency));

//will print 135.69

There are two aspects to your questions: what are the technical aspects of using const instead of var and what are the human-related aspects of doing so.

The technical difference is significant. In compiled languages, a constant will be replaced at compile-time and its use will allow for other optimizations like dead code removal to further increase the runtime efficiency of the code. Recent (loosely used term) JavaScript engines actually compile JS code to get better performance, so using the const keyword would inform them that the optimizations described above are possible and should be done. This results in better performance.

The human-related aspect is about the semantics of the keyword. A variable is a data structure that contains information that is expected to change. A constant is a data structure that contains information that will never change. If there is room for error, var should always be used. However, not all information that never changes in the lifetime of a program needs to be declared with const. If under different circumstances the information should change, use var to indicate that, even if the actual change doesn't appear in your code.

My variation that I find to be more flexible.

str_Key           = ""
str_FullKey       = "" 
str_CharacterPool = "01234ABCDEFfghij~-)"
for int_I in range(64): 
    str_Key = random.choice(str_CharacterPool) 
    str_FullKey = str_FullKey + str_Key

or code?

JButton b = new JButton("Clear");
b.addActionListener(new ActionListener(){

Your usage of now() is correct. However, you need to use one type of quotes around the entire query and another around the values.

You can modify your query to use double quotes at the beginning and end, and single quotes around $somename:

$update_query = "UPDATE db.tablename SET insert_time=now() WHERE username='$somename'";

A current release of Android Studio did not correctly apply the -tcpdump argument. I was still able to capture a dump by passing the related parameter to qemu as follows:

You don't need arrays for this. Try something like:

ActiveSheet.Range("$A$1:$A$" & LastRow).RemoveDuplicates Columns:=1, Header:=xlYes

If there's no header, change accordingly.

EDIT: Here's the traditional method, which takes advantage of the fact that each item in a Collection must have a unique key:

Sub test()
Dim ws As Excel.Worksheet
Dim LastRow As Long
Dim coll As Collection
Dim cell As Excel.Range
Dim arr() As String
Dim i As Long

Set ws = ActiveSheet
With ws
    LastRow = .Range("C" & .Rows.Count).End(xlUp).Row
    Set coll = New Collection
    For Each cell In .Range("C4:C" & LastRow)
        On Error Resume Next
        coll.Add cell.Value, CStr(cell.Value)
        On Error GoTo 0
    Next cell
    ReDim arr(1 To coll.Count)
    For i = LBound(arr) To UBound(arr)
        arr(i) = coll(i)
        'to show in Immediate Window
        Debug.Print arr(i)
    Next i
End With
End Sub

In my case TLS1_2 was enabled both on client and server but the server was using MD5 while client disabled it. So, test both client and server on http://ssllabs.com or test using openssl/s_client to see what's happening. Also, check the selected cipher using Wireshark.

If you are using Java configuration in a spring-data-jpa project, make sure you are scanning the package that the entity is in. For example, if the entity lived com.foo.myservice.things then the following configuration annotation below would not pick it up.

You could fix it by loosening it up to just com.foo.myservice (of course, keep in mind any other effects of broadening your scope to scan for entities).

@Configuration
@EnableJpaAuditing
@EnableJpaRepositories("com.foo.myservice.repositories")
public class RepositoryConfiguration {
}

If your intention is test the service without care about the rest call, I will suggest to not use any annotation in your unit test to simplify the test.

So, my suggestion is refactor your service to receive the resttemplate using injection constructor. This will facilitate the test. Example:

@Service
class SomeService {
    @AutoWired
    SomeService(TestTemplateObjects restTemplateObjects) {
        this.restTemplateObjects = restTemplateObjects;
    }
}

The RestTemplate as component, to be injected and mocked after:

@Component
public class RestTemplateObjects {

    private final RestTemplate restTemplate;

    public RestTemplateObjects () {
        this.restTemplate = new RestTemplate();
        // you can add extra setup the restTemplate here, like errorHandler or converters
    }

    public RestTemplate getRestTemplate() {
        return restTemplate;
    }
}

And the test:

public void test() {

    when(mockedRestTemplateObject.get).thenReturn(mockRestTemplate);

    //mock restTemplate.exchange
    when(mockRestTemplate.exchange(...)).thenReturn(mockedResponseEntity);

    SomeService someService = new SomeService(mockedRestTemplateObject);
    someService.getListofObjectsA();
}

In this way, you have direct access to mock the rest template by the SomeService constructor.

Put this in your server directive:

location /issue {
   rewrite ^/issue(.*) http://$server_name/shop/issues/custom_issue_name$1 permanent;
 }

Or duplicate it:

location /issue1 {
   rewrite ^/.* http://$server_name/shop/issues/custom_issue_name1 permanent;
}
location /issue2 {
   rewrite ^.* http://$server_name/shop/issues/custom_issue_name2 permanent;
}
 ...

I tried this using Lambda expression, and it worked.

List<MyList>.Any (x => (String.Equals(x.Name, name, StringComparison.OrdinalIgnoreCase)) && (x.Type == qbType) );

int g[] = {9,8};

This declares an object of type int[2], and initializes its elements to {9,8}

int (*j) = g;

This declares an object of type int *, and initializes it with a pointer to the first element of g.

The fact that the second declaration initializes j with something other than g is pretty strange. C and C++ just have these weird rules about arrays, and this is one of them. Here the expression g is implicitly converted from an lvalue referring to the object g into an rvalue of type int* that points at the first element of g.

This conversion happens in several places. In fact it occurs when you do g[0]. The array index operator doesn't actually work on arrays, only on pointers. So the statement int x = j[0]; works because g[0] happens to do that same implicit conversion that was done when j was initialized.

A pointer to an array is declared like this

int (*k)[2];

and you're exactly right about how this would be used

int x = (*k)[0];

(note how "declaration follows use", i.e. the syntax for declaring a variable of a type mimics the syntax for using a variable of that type.)

However one doesn't typically use a pointer to an array. The whole purpose of the special rules around arrays is so that you can use a pointer to an array element as though it were an array. So idiomatic C generally doesn't care that arrays and pointers aren't the same thing, and the rules prevent you from doing much of anything useful directly with arrays. (for example you can't copy an array like: int g[2] = {1,2}; int h[2]; h = g;)

Examples:

void foo(int c[10]); // looks like we're taking an array by value.
// Wrong, the parameter type is 'adjusted' to be int*

int bar[3] = {1,2};
foo(bar); // compile error due to wrong types (int[3] vs. int[10])?
// No, compiles fine but you'll probably get undefined behavior at runtime

// if you want type checking, you can pass arrays by reference (or just use std::array):
void foo2(int (&c)[10]); // paramater type isn't 'adjusted'
foo2(bar); // compiler error, cannot convert int[3] to int (&)[10]

int baz()[10]; // returning an array by value?
// No, return types are prohibited from being an array.

int g[2] = {1,2};
int h[2] = g; // initializing the array? No, initializing an array requires {} syntax
h = g; // copying an array? No, assigning to arrays is prohibited

Because arrays are so inconsistent with the other types in C and C++ you should just avoid them. C++ has std::array that is much more consistent and you should use it when you need statically sized arrays. If you need dynamically sized arrays your first option is std::vector.

md5.h also have MD5_* functions very useful for big file

#include <openssl/md5.h>
#include <fstream>
.......

std::ifstream file(filename, std::ifstream::binary);
MD5_CTX md5Context;
MD5_Init(&md5Context);
char buf[1024 * 16];
while (file.good()) {
    file.read(buf, sizeof(buf));
    MD5_Update(&md5Context, buf, file.gcount());
}
unsigned char result[MD5_DIGEST_LENGTH];
MD5_Final(result, &md5Context);

Very simple, isn`t it? Convertion to string also very simple:

#include <sstream>
#include <iomanip>
.......

std::stringstream md5string;
md5string << std::hex << std::uppercase << std::setfill('0');
for (const auto &byte: result)
    md5string << std::setw(2) << (int)byte;

return md5string.str();

The difference between page and window with respect to WPF: Page vs Window in WPF?

 instance.__class__.__name__

example:

>>> class A():
    pass
>>> a = A()
>>> a.__class__.__name__
'A'

This is long one but a full proof solution, never fails

Just pass your number to this function as a double, it will return you rounding the decimal value up to the nearest value of 5;

if 4.25, Output 4.25

if 4.20, Output 4.20

if 4.24, Output 4.20

if 4.26, Output 4.30

if you want to round upto 2 decimal places,then use

DecimalFormat df = new DecimalFormat("#.##");
roundToMultipleOfFive(Double.valueOf(df.format(number)));

if up to 3 places, new DecimalFormat("#.###")

if up to n places, new DecimalFormat("#.nTimes #")

 public double roundToMultipleOfFive(double x)
            {

                x=input.nextDouble();
                String str=String.valueOf(x);
                int pos=0;
                for(int i=0;i<str.length();i++)
                {
                    if(str.charAt(i)=='.')
                    {
                        pos=i;
                        break;
                    }
                }

                int after=Integer.parseInt(str.substring(pos+1,str.length()));
                int Q=after/5;
                int R =after%5;

                if((Q%2)==0)
                {
                    after=after-R;
                }
                else
                {
                   if(5-R==5)
                   {
                     after=after;
                   }
                   else after=after+(5-R);
                }

                       return Double.parseDouble(str.substring(0,pos+1).concat(String.valueOf(after))));

            }

Also answering this question:

Where can I get pre-built JavaFX libraries for OpenJDK (Windows)

On Linux its not really a problem, but on Windows its not that easy, especially if you want to distribute the JRE.

You can actually use OpenJFX with OpenJDK 8 on windows, you just have to assemble it yourself:

Download the OpenJDK from here: https://github.com/AdoptOpenJDK/openjdk8-releases/releases/tag/jdk8u172-b11

Download OpenJFX from here: https://github.com/SkyLandTW/OpenJFX-binary-windows/releases/tag/v8u172-b11

copy all the files from the OpenFX zip on top of the JDK, voila, you have an OpenJDK with JavaFX.

Update:

Fortunately from Azul there is now a OpenJDK+OpenJFX build which can be downloaded at their community page: https://www.azul.com/downloads/zulu-community/?&version=java-8-lts&os=windows&package=jdk-fx

Thanks to cryo for improved version that I based my tested code below:

#Instead of adding silence at start and end of recording (values=0) I add the original audio . This makes audio sound more natural as volume is >0. See trim()

tar.gz file is just a tar file that's been gzipped. Both tar and gzip are available for windows.

If you like GUIs (Graphical user interface), 7zip can pack with both tar and gzip.

ssh -t 'command; bash -l'

will execute the command and then start up a login shell when it completes. For example:

ssh -t [email protected] 'cd /some/path; bash -l'

if you hava a logback-spring.xml or something like that, add the following code to it

<logger name="org.hibernate.SQL" level="trace" additivity="false">
    <appender-ref ref="file" />
</logger>

works for me.

To get bind variables as well:

<logger name="org.hibernate.type.descriptor.sql" level="trace">
    <appender-ref ref="file" />
</logger>

When you created the WebForm, did you select the Master page it is attached to in the "Add New Item" dialog itself ? Or did you attach it manually using the MasterPageFile attribute of the @Page directive ? If it was the latter, it might explain the error message you receive.

VS automatically inserts certain markup in each kind of page. If you select the MasterPage at the time of page creation itself, it does not generate any markup except the @Page declaration and the top level Content control.

I would break up

public static void main(String args[])

in parts:

public

It means that you can call this method from outside of the class you are currently in. This is necessary because this method is being called by the Java runtime system which is not located in your current class.

static

When the JVM makes call to the main method there is no object existing for the class being called therefore it has to have static method to allow invocation from class.

void

Java is platform independent language and if it will return some value then the value may mean different things to different platforms. Also there are other ways to exit the program on a multithreaded system. Detailed explaination.

main

It's just the name of method. This name is fixed and as it's called by the JVM as entry point for an application.

String args[]

These are the arguments of type String that your Java application accepts when you run it.

string = "TEST"
try:
  if str(string):
     print "good string"
except NameError:
     print "bad string"

The main concept of partial view is returning the HTML code rather than going to the partial view it self.

[HttpGet]
public ActionResult Calendar(int year)
{
    var dates = new List<DateTime>() { /* values based on year */ };
    HolidayViewModel model = new HolidayViewModel {
        Dates = dates
    };
    return PartialView("HolidayPartialView", model);
}

this action return the HTML code of the partial view ("HolidayPartialView").

To refresh partial view replace the existing item with the new filtered item using the jQuery below.

$.ajax({
                url: "/Holiday/Calendar",
                type: "GET",
                data: { year: ((val * 1) + 1) }
            })
            .done(function(partialViewResult) {
                $("#refTable").html(partialViewResult);
            });

            #   sys.stdout.write(" ")
            if self.buffer == None:
                self.buffer = ""
            self.buffer += self.despace_re.sub(" ", data).strip()
            self.data_interrupt = False

parser = HTMLTableParser() 
parser.feed(sys.stdin.read())

One enhancement for this script could be to add support for specifying a different line delimiter (or auto-calculate the platform-correct one), and a different column delimiter.

Reducing just the padding on the columns won't make the trick, as you will extend the width of the page, making it uneven with the rest of your page, say navbar. You need to equally reduce the negative margin on the row. Taking @martinedwards' LESS example:

.row-no-padding {
  margin-left: 0;
  margin-right: 0;
  [class*="col-"] {
    padding-left: 0 !important;
    padding-right: 0 !important;
  }
}

This will give you everything column property related.

SELECT * INTO TMP1
FROM ( SELECT TOP 1 /* rest of your query expression here */ );

SELECT o.name AS obj_name, TYPE_NAME(c.user_type_id) AS type_name, c.*  
FROM sys.objects AS o   
JOIN sys.columns AS c  ON o.object_id = c.object_id  
WHERE o.name = 'TMP1';

DROP TABLE TMP1;

All of the paths above assume that your objects are serializable to XML or JSON,
or you must implement your own solution.

But in the end you still get to the point where you have to solve problems like

• recursion in objects
• non-serializable objects
• exceptions
• ...

Plus log you want more information:

• when the event happened
• callstack
• which threead
• what was in the web session
• which ip address
• url
• ...

There is the best solution that solves all of this and much more.
Use this Nuget package: Desharp.
For all types of applications - both web and desktop applications.
See it's Desharp Github documentation. It has many configuration options.

Just call anywhere:

Desharp.Debug.Log(anyException);
Desharp.Debug.Log(anyCustomValueObject);
Desharp.Debug.Log(anyNonserializableObject);
Desharp.Debug.Log(anyFunc);
Desharp.Debug.Log(anyFunc, Desharp.Level.EMERGENCY); // you can store into different files

• it can save the log in nice HTML (or in TEXT format, configurable)
• it's possible to write optionally in background thread (configurable)
• it has options for max objects depth and max strings length (configurable)
• it uses loops for iteratable objects and backward reflection for everything else,
  indeed for anything you can find in .NET environment.

I believe it will help.

Unfortunately all the answers in this post didn't work for me. I kept getting following error.

Failed to execute 'write' on 'Document': It isn't possible to write into a document from an asynchronously-loaded external script unless it is explicitly opened.

I found out that this happens if you use some 3rd party widgets (demandforce in my case) that also call additional external JavaScript files and try to insert HTML. Looking at the console and the JavaScript code, I noticed multiple lines like this:

document.write("<script type='text/javascript' "..."'></script>");

I used 3rd party JavaScript files (htmlParser.js and postscribe.js) from: https://github.com/krux/postscribe. That solved the problem in this post and fixed the above error at the same time.

(This was a quick and dirty way around under the tight deadline I have now. I am not comfortable with using 3rd party JavaScript library however. I hope someone can come up with a cleaner and better way.)

in preferences --> PyDev --> PyLint under arguments to pass to PyLint add this line:

--generated-members=objects

you will need to do this for each generated . I found this by googling, but I lost the reference.

Here is the example how to compare to arrays and get what is different between them.

$array1 = ['1' => 'XXX', 'second' => [
            'a' => ['test' => '2'],
            'b' => 'test'
        ], 'b' => ['no test']];

        $array2 = [
            '1' => 'XX',
            'second' => [
                'a' => ['test' => '5', 'z' => 5],
                'b' => 'test'
            ],
            'test'
        ];


        function compareArrayValues($arrayOne, $arrayTwo, &$diff = [], $reversed = false)
        {
            foreach ($arrayOne as $key => $val) {
                if (!isset($arrayTwo[$key])) {
                    $diff[$key] = 'MISSING IN ' . ($reversed ? 'FIRST' : 'SECOND');
                } else if (is_array($val) && (json_encode($arrayOne[$key]) !== json_encode($arrayTwo[$key]))) {
                    compareArrayValues($arrayOne[$key], $arrayTwo[$key], $diff[$key], $reversed);
                } else if ($arrayOne[$key] !== $arrayTwo[$key]) {
                    $diff[$key] = 'DIFFERENT';
                }
            }
        }

        $diff = [];
        $diffSecond = [];

        compareArrayValues($array1, $array2, $diff);
        compareArrayValues($array2, $array1, $diffSecond, true);

        print_r($diff);
        print_r($diffSecond);

        print_r(array_merge($diff, $diffSecond));

Result:

Array
(
    [0] => DIFFERENT
    [second] => Array
        (
            [a] => Array
                (
                    [test] => DIFFERENT
                    [z] => MISSING IN FIRST
                )

        )

    [b] => MISSING IN SECOND
    [1] => DIFFERENT
    [2] => MISSING IN FIRST
)

When you say str, you should be careful what you mean:

• do you mean the variable str?

• or do you mean the object referenced by str?

In your StringBuffer example you are not altering the value of str, and in your String example you are not altering the state of the String object.

The most poignant way to experience the difference would be something like this:

static void change(String in) { 
  in = in + " changed";
}

static void change(StringBuffer in) {
  in.append(" changed");
}

public static void main(String[] args) {
   StringBuffer sb = new StringBuffer("value");
   String str = "value";
   change(sb);
   change(str);
   System.out.println("StringBuffer: "+sb);
   System.out.println("String: "+str);
}

HttpClient lives in the System.Net.Http namespace.

You'll need to add:

using System.Net.Http;

And make sure you are referencing System.Net.Http.dll in .NET 4.5.

The code posted doesn't appear to do anything with webClient. Is there something wrong with the code that is actually compiling using HttpWebRequest?

Update

To open the Add Reference dialog right-click on your project in Solution Explorer and select Add Reference.... It should look something like:

Looking at the droplevels methods code in the R source you can see it wraps to factor function. That means you can basically recreate the column with factor function.
Below the data.table way to drop levels from all the factor columns.

library(data.table)
dt = data.table(letters=factor(letters[1:5]), numbers=seq(1:5))
levels(dt$letters)
#[1] "a" "b" "c" "d" "e"
subdt = dt[numbers <= 3]
levels(subdt$letters)
#[1] "a" "b" "c" "d" "e"

upd.cols = sapply(subdt, is.factor)
subdt[, names(subdt)[upd.cols] := lapply(.SD, factor), .SDcols = upd.cols]
levels(subdt$letters)
#[1] "a" "b" "c"

You can use

t1<- t1[-4:-6,-7:-9]  

or

t1 <- t1[-(4:6), -(7:9)]

or

t1 <- t1[-c(4, 5, 6), -c(7, 8, 9)]

You can pass vectors to select rows/columns to be deleted. First two methods are useful if you are trying to delete contiguous rows/columns. Third method is useful if You are trying to delete discrete rows/columns.

> t1 <- array(1:20, dim=c(10,10));

> t1[-c(1, 4, 6, 7, 9), -c(2, 3, 8, 9)]

     [,1] [,2] [,3] [,4] [,5] [,6]
[1,]    2   12    2   12    2   12
[2,]    3   13    3   13    3   13
[3,]    5   15    5   15    5   15
[4,]    8   18    8   18    8   18
[5,]   10   20   10   20   10   20

For Bash/Python, here is a basic wrapper around python's simplejson:

json_parser() {
    local jsonfile="my_json_file.json"
    local tc="import simplejson,sys; myjsonstr=sys.stdin.read(); "`
            `"myjson=simplejson.loads(myjsonstr);"
    # Build python print command based on $@
    local printcmd="print myjson"
    for (( argn=1; argn<=$#; argn++ )); do
        printcmd="$printcmd['${!argn}']"
    done
    local result=$(python -c "$tc $printcmd.keys()" <$jsonfile 2>/dev/null \
        || python -c "$tc $printcmd" <$jsonfile 2>/dev/null)
    # For returning space-separated values
    echo $result|sed -e "s/[]|[|,|']//g"
    #echo $result 
}

It really only handles the nested-dictionary style of data, but it works for what I needed, and is useful for walking through the json. It could probably be adapted to taste.

Anyway, something homegrown for those not wanting to source in yet another external dependency. Except for python, of course.

Ex. json_parser {field1} {field2} would run print myjson['{field1}']['{field2}'], yielding either the keys or the values associated with {field2}, space-separated.

What worked for me was fs.promises.

Example One:

const fs = require("fs")

fs.promises
  .writeFile(__dirname + '/test.json', "data", { encoding: 'utf8' })
  .then(() => {
    // Do whatever you want to do.
    console.log('Done');
  });

Example Two. Using Async-Await:

const fs = require("fs")

async function writeToFile() {
  await fs.promises.writeFile(__dirname + '/test-22.json', "data", {
    encoding: 'utf8'
  });

  console.log("done")
}

writeToFile()

You can use Context.checkCallingorSelfPermission() function for this. Here is an example:

private boolean checkWriteExternalPermission()
{
    String permission = android.Manifest.permission.WRITE_EXTERNAL_STORAGE;
    int res = getContext().checkCallingOrSelfPermission(permission);
    return (res == PackageManager.PERMISSION_GRANTED);            
}

How about:

class MyClass(object):
    def __init__(self, filename):
        self.filename = filename 
        self.stats = parse_file(filename)

def parse_file(filename):
    #do some parsing
    return results_from_parse

By the way, if you have variables named stat1, stat2, etc., the situation is begging for a tuple: stats = (...).

So let parse_file return a tuple, and store the tuple in self.stats.

Then, for example, you can access what used to be called stat3 with self.stats[2].

Visualizing the tree structure was the most convenient way for me :

public static void main(String[] args) throws IOException {
    printTree(0, new File("START/FROM/DIR"));
}

static void printTree(int depth, File file) throws IOException { 
    StringBuilder indent = new StringBuilder();
    String name = file.getName();

    for (int i = 0; i < depth; i++) {
        indent.append(".");
    }

    //Pretty print for directories
    if (file.isDirectory()) { 
        System.out.println(indent.toString() + "|");
        if(isPrintName(name)){
            System.out.println(indent.toString() + "*" + file.getName() + "*");
        }
    }
    //Print file name
    else if(isPrintName(name)) {
        System.out.println(indent.toString() + file.getName()); 
    }
    //Recurse children
    if (file.isDirectory()) { 
        File[] files = file.listFiles(); 
        for (int i = 0; i < files.length; i++){
            printTree(depth + 4, files[i]);
        } 
    }
}

//Exclude some file names
static boolean isPrintName(String name){
    if (name.charAt(0) == '.') {
        return false;
    }
    if (name.contains("svn")) {
        return false;
    }
    //.
    //. Some more exclusions
    //.
    return true;
}

I want to add that when using Windows you can use require './1.rb' if the script is run local or from a mapped network drive but when run from an UNC \\servername\sharename\folder path you need to use require_relative './1.rb'.

I don't mingle in the discussion which to use for other reasons.

Libpng-1.6 is more stringent about checking ICC profiles than previous versions. You can ignore the warning. To get rid of it, remove the iCCP chunk from the PNG image.

Some applications treat warnings as errors; if you are using such an application you do have to remove the chunk. You can do that with any of a variety of PNG editors such as ImageMagick's

convert in.png out.png

To remove the invalid iCCP chunk from all of the PNG files in a folder (directory), you can use mogrify from ImageMagick:

mogrify *.png

This requires that your ImageMagick was built with libpng16. You can easily check it by running:

convert -list format | grep PNG

If you'd like to find out which files need to be fixed instead of blindly processing all of them, you can run

pngcrush -n -q *.png

where the -n means don't rewrite the files and -q means suppress most of the output except for warnings. Sorry, there's no option yet in pngcrush to suppress everything but the warnings.

Binary Releases of ImageMagick are here

For Android Projects (Android Studio) navigate into res folder.

For example:

C:\{your_project_folder}\app\src\main\res\drawable-hdpi\mogrify *.png

Closure are not difficult to understand. It depends only from the point of view.

I personally like to use them in cases of daily life.

function createCar()
{
    var rawMaterial = [/* lots of object */];
    function transformation(rawMaterials)
    {
       /* lots of changement here */
       return transformedMaterial;
    }
    var transformedMaterial = transformation(rawMaterial);
    function assemblage(transformedMaterial)
    {
        /*Assemblage of parts*/
        return car;
    }
    return assemblage(transformedMaterial);
}

We only need to go through certain steps in particular cases. As for the transformation of materials is only useful when you have the parts.

We can use append

append(l1, l2)

It also has arguments to insert element at a particular location.

2019's answer as this is still actively seen today

You should likely change the .container to .container-fluid, which will cause your container to stretch the entire screen. This will allow any div's inside of it to naturally stretch as wide as they need.

original hack from 2015 that still works in some situations

You should pull that div outside of the container. You're asking a div to stretch wider than its parent, which is generally not recommended practice.

If you cannot pull it out of the div for some reason, you should change the position style with this css:

.full-width-div {
    position: absolute;
    width: 100%;
    left: 0;
}

Instead of absolute, you could also use fixed, but then it will not move as you scroll.

You can also try ExcelPython which allows you to manipulate Python object and call code from VBA.

If you are using Apache, mod_rewrite is the easiest solution, and has a lot of documentation online how to do that. For example: http://www.askapache.com/htaccess/http-https-rewriterule-redirect.html

You are looking for dynamic_cast<B*>(pointer)

Execute this script:

SELECT 'ALTER SYSTEM KILL SESSION '''||sid||','||serial#||''' IMMEDIATE;' 
FROM v$session 
where username='YOUR_USER';

It will printout sqls, which should be executed.

For Python2.7

You can format it into seconds and then multiply by 1000 to convert to millisecond.

from datetime import datetime

d = datetime.strptime("20.12.2016 09:38:42,76", "%d.%m.%Y %H:%M:%S,%f").strftime('%s')
d_in_ms = int(d)*1000
print(d_in_ms)

print(datetime.fromtimestamp(float(d)))

Output:

1482206922000
2016-12-20 09:38:42

Javascript is not object oriented programming(OOP) language therefore the LOOK UP process in javascript work using 'DELEGATION PROCESS' also known as prototype delegation or prototypical inheritance.

If you try to get the value of a property from an object that it doesn't have, the JavaScript engine looks to the object's prototype (and its prototype, 1 step above at a time) it's prototype chain untll the chain ends upto null which is Object.prototype == null (Standard Object Prototype). At this point if property or method is not defined than undefined is returned.

Thus with the new keyword some of the task that were manually done e.g

1. Manual Object Creation e.g newObj.
2. Hidden bond Creation using proto (aka: dunder proto) in JS spec [[prototype]] (i.e. proto)
3. referencing and assign properties to newObj
4. return of newObj object.

All is done manually.

function CreateObj(value1, value2) {
  const newObj = {};
  newObj.property1 = value1;
  newObj.property2 = value2;
  return newObj;
}
var obj = CreateObj(10,20);

obj.__proto__ === Object.prototype;              // true
Object.getPrototypeOf(obj) === Object.prototype // true

Javascript Keyword new helps to automate this process:

1. new object literal is created identified by this:{}
2. referencing and assign properties to this
3. Hidden bond Creation [[prototype]] (i.e. proto) to Function.prototype shared space.
4. implicit return of this object {}

function CreateObj(value1, value2) {
  this.property1 = value1;
  this.property2 = value2;
}

var obj = new CreateObj(10,20);
obj.__proto__ === CreateObj.prototype             // true
Object.getPrototypeOf(obj) == CreateObj.prototype // true

Calling Constructor Function without the new Keyword:

=> this: Window

function CreateObj(value1, value2) {
  var isWindowObj = this === window;
  console.log("Is Pointing to Window Object", isWindowObj);
  this.property1 = value1;
  this.property2 = value2;
}
var obj = new CreateObj(10,20); // Is Pointing to Window Object false
var obj = CreateObj(10,20); // Is Pointing to Window Object true
window.property1; // 10
window.property2; // 20

Yes you can start with the Wikipedia article explaining the Big O notation, which in a nutshell is a way of describing the "efficiency" (upper bound of complexity) of different type of algorithms. Or you can look at an earlier answer where this is explained in simple english

When you #include a header, it's exactly as if you put the code into the source file itself. In both cases the varGlobal variable is defined in the source so it will work no matter how it's declared.

Also as pointed out in the comments, C++ variables at file scope are not static in scope even though they will be assigned to static storage. If the variable were a class member for example, it would need to be accessible to other compilation units in the program by default and non-class members are no different.

I had this problem too. Problem is comming from html, created by bootstrap js:

<div class="modal-backdrop fade in"></div>

This line is created directly before end of <body> element. This cause "z-index stacked element problem." I believe that bootstrap .js do creation of this element wrong. If you have in mvc layout page, this script will cause still the same problem. Beter js idea cut be to get target modal id and inject this line to html before...

this.$backdrop = $(document.createElement('div'))
    .addClass('modal-backdrop ' + animate)
    .appendTo(this.$body)

SO SOLUTION IS repair bootstrap.js - part of modal:

.appendTo(this.$body)  
//REPLACE TO THIS:
 .insertBefore(this.$element) 

Write an expect script.

Here is an example:

#!/usr/bin/expect

#If it all goes pear shaped the script will timeout after 20 seconds.
set timeout 20
#First argument is assigned to the variable name
set name [lindex $argv 0]
#Second argument is assigned to the variable user
set user [lindex $argv 1]
#Third argument is assigned to the variable password
set password [lindex $argv 2]
#This spawns the telnet program and connects it to the variable name
spawn telnet $name 
#The script expects login
expect "login:" 
#The script sends the user variable
send "$user "
#The script expects Password
expect "Password:"
#The script sends the password variable
send "$password "
#This hands control of the keyboard over to you (Nice expect feature!)
interact

To run:

./myscript.expect name user password

My first thought was to try passing it '30/03/09 16:31:32.123' (with a period instead of a colon between the seconds and the milliseconds.) But that didn't work. A quick glance at the docs indicates that fractional seconds are ignored in any case...

Ah, version differences. This was reported as a bug and now in 2.6+ you can use "%S.%f" to parse it.

I'm using Fedora 25

sudo dnf search php | grep mysql

Though it is answered above and it is right to use

<meta name="viewport" content="width=device-width, initial-scale=1">

but if you are using React and webpack then don't forget to close the element tag

<meta name="viewport" content="width=device-width, initial-scale=1" />

System.Guid desiredGuid = System.Guid.NewGuid();

My 2 cents.

This is a loaded question imho. A rule of thumb I use to is see how this function will be called. If the caller is something I have control over then , its ok to assume that it will be called with the right parameters and with proper initialization.

On the other hand if its some client I don't control then it is a good idea to do thorough error checking.

I had to fix this by decreasing the priority (making it higher). This caused an immediate response. Not what I was expecting, but it worked.

Objects will be cleaned up when they are no longer being used and when the garbage collector sees fit. Sometimes, you may need to set an object to null in order to make it go out of scope (such as a static field whose value you no longer need), but overall there is usually no need to set to null.

Regarding disposing objects, I agree with @Andre. If the object is IDisposable it is a good idea to dispose it when you no longer need it, especially if the object uses unmanaged resources. Not disposing unmanaged resources will lead to memory leaks.

You can use the using statement to automatically dispose an object once your program leaves the scope of the using statement.

using (MyIDisposableObject obj = new MyIDisposableObject())
{
    // use the object here
} // the object is disposed here

Which is functionally equivalent to:

MyIDisposableObject obj;
try
{
    obj = new MyIDisposableObject();
}
finally
{
    if (obj != null)
    {
        ((IDisposable)obj).Dispose();
    }
}

I don't think the other answers are working any more, as conda stopped automatically setting environments up as jupyter kernels. You need to manually add kernels for each environment in the following way:

source activate myenv
python -m ipykernel install --user --name myenv --display-name "Python (myenv)"

As documented here:http://ipython.readthedocs.io/en/stable/install/kernel_install.html#kernels-for-different-environments Also see this issue.

Addendum: You should be able to install the nb_conda_kernels package with conda install nb_conda_kernels to add all environments automatically, see https://github.com/Anaconda-Platform/nb_conda_kernels

Another reply to your questions (assuming you are on master and already did "git fetch origin" to make you repo aware about remote changes):

1) Commits on remote branch since when local branch was created:

git diff HEAD...origin/master

2) I assume by "working copy" you mean your local branch with some local commits that are not yet on remote. To see the differences of what you have on your local branch but that does not exist on remote branch run:

git diff origin/master...HEAD

3) See the answer by dbyrne.

I can think of one unfortunate side-effect. In java embedded databases, the number of ids you can have with a 32bit id field is 2^31, not 2^32 (~2billion, not ~4billion).

To print keys on one line as csv:

echo '{"b":"2","a":"1"}' | jq -r 'keys | [ .[] | tostring ] | @csv'

Output:

"a","b"

For csv completeness ... to print values on one line as csv:

echo '{"b":"2","a":"1"}' | jq -rS . | jq -r '. | [ .[] | tostring ] | @csv'

Output:

"1","2"

The syntax for index hints is documented here:

If you're using ORDER BY before GROUP BY to get the latest entry per owner_id, you're using a nonstandard and undocumented behavior of MySQL to do that.

There's no guarantee that it'll continue to work in future versions of MySQL, and the query is likely to be an error in any other RDBMS.

Search the greatest-n-per-group tag for many explanations of better solutions for this type of query.

A degree of control is possible over how information travels from a third-party website to Facebook when a page is shared (or liked, etc.). In order to make this possible, information is sent via Open Graph meta tags in the <head> part of the website’s code.

There is a solution to this if you really need a static access to the current context. In Startup.Configure(….)

app.Use(async (httpContext, next) =>
{
    CallContext.LogicalSetData("CurrentContextKey", httpContext);
    try
    {
        await next();
    }
    finally
    {
        CallContext.FreeNamedDataSlot("CurrentContextKey");
    }
});

And when you need it you can get it with :

HttpContext context = CallContext.LogicalGetData("CurrentContextKey") as HttpContext;

I hope that helps. Keep in mind this workaround is when you don’t have a choice. The best practice is to use de dependency injection.

I use a Dictionary and because of the repetetiveness and possible missing keys, I quickly patched together a small method:

 private static string GetKey(IReadOnlyDictionary<string, string> dictValues, string keyValue)
 {
     return dictValues.ContainsKey(keyValue) ? dictValues[keyValue] : "";
 }

Calling it:

var entry = GetKey(dictList,"KeyValue1");

Gets the job done.

Does this work:

$msgid = $_GET['msgid'];

$oldMessage = '';

$deletedFormat = '';

//read the entire string
$str=file_get_contents('msghistory.txt');

//replace something in the file string - this is a VERY simple example
$str=str_replace($oldMessage, $deletedFormat,$str);

//write the entire string
file_put_contents('msghistory.txt', $str);

In my case the solution was easy. You don't need to declare anything in your web.xml.

Because your project is a web application, the config file should be on WEB-INF/classes after deployment. I advise you to create a Java resource folder (src/main/resources) to do that (best pratice). Another approach is to put the config file in your src/main/java.

Beware with the configuration file name. If you are using XML, the file name is log4j.xml, otherwise log4j.properties.

If you know the the name of the file and if you always want to download that specific file, then you can easily get the ID and other attributes for your desired file from: https://developers.google.com/drive/v2/reference/files/list (towards the bottom you will find a way to run queries). In the q field enter title = 'your_file_name' and run it. You should see some result show up right below and within it should be an "id" field. That is the id you are looking for.

You can also play around with additional parameters from: https://developers.google.com/drive/search-parameters

If you want to get a single value from Database

    Model::where('id', 1)->value('name')

Options -Indexes perfectly works for me ,

here is .htaccess file :

<IfModule mod_rewrite.c>
    <IfModule mod_negotiation.c>
        Options -MultiViews -Indexes <---- This Works for Me :)
    </IfModule>


   ....etc stuff

</IfModule>

The question has been asked on serverfault too.

You may want to take a look at this article which explains a lot about MySQL row sizes. It's important to note that even if you use TEXT or BLOB fields, your row size could still be over 8K (limit for InnoDB) because it stores the first 768 bytes for each field inline in the page.

The simplest way to fix this is to use the Barracuda file format with InnoDB. This basically gets rid of the problem altogether by only storing the 20 byte pointer to the text data instead of storing the first 768 bytes.

The method that worked for the OP there was:

1. Add the following to the my.cnf file under [mysqld] section.

   innodb_file_per_table=1
   innodb_file_format = Barracuda
   

2. ALTER the table to use ROW_FORMAT=COMPRESSED.

   ALTER TABLE nombre_tabla
       ENGINE=InnoDB
       ROW_FORMAT=COMPRESSED 
       KEY_BLOCK_SIZE=8;
   

There is a possibility that the above still does not resolve your issues. It is a known (and verified) bug with the InnoDB engine, and a temporary fix for now is to fallback to MyISAM engine as temporary storage. So, in your my.cnf file:

internal_tmp_disk_storage_engine=MyISAM

Tried this on firefox, works http://jsfiddle.net/Tm26Q/1/

$(function(){
 /** Just to mimic a blinking box on the page**/
  setInterval(function(){$("div#box").hide();},2001);
  setInterval(function(){$("div#box").show();},1000);
 /**/
});

$("div#box").on("DOMAttrModified",
function(){if($(this).is(":visible"))console.log("visible");});

UPDATE

Currently the Mutation Events (like DOMAttrModified used in the solution) are replaced by MutationObserver, You can use that to detect DOM node changes like in the above case.

I had the same issue when uninstalled my Python27 and re-installed it.

I downloaded the sip-4.15.5 and PyQt-win-gpl-4.10.4 and installed/configured both of them. it still gives 'ImportError: No module named PyQt4.QtCore'. I tried to move the files/folders in Lib to make it looked 'have' but not working.

in fact, jut download the Windows 64 bit installer for a suitable Python version (my case) from http://www.riverbankcomputing.co.uk/software/pyqt/download and installed it, will do the job.

* March 2017 update *

The given link says, Binary installers for Windows are no longer provided.

See cgohlke's answer at, PyQt4 and 64-bit python.

1. Download the .whl file at http://www.lfd.uci.edu/~gohlke/pythonlibs/#pyqt4.
2. Use pip to install the downloaded .whl file.

I'll just update the code to contain the changes, and comment it to so that you can see what's going on clearly...

<?php   
include("templates/header.htm");   

// Set the default name 
$action = 'index'; 
// Specify some disallowed paths 
$disallowed_paths = array('header', 'footer'); 
if (!empty($_GET['action'])) { 
    $tmp_action = basename($_GET['action']); 
    // If it's not a disallowed path, and if the file exists, update $action 
    if (!in_array($tmp_action, $disallowed_paths) && file_exists("templates/{$tmp_action}.htm")) 
        $action = $tmp_action; 
} 
// Include $action 
include("templates/$action.htm"); 

include("templates/footer.htm");

Add the below to your manifest:

  <activity   android:name=".AppPreferenceActivity" android:label="@string/app_name">  
     <intent-filter> 
       <action android:name="com.scytec.datamobile.vd.gui.android.AppPreferenceActivity" />  
       <category android:name="android.intent.category.DEFAULT" />  
     </intent-filter>   
  </activity>

Whenever you wanted to make a layout scrollable, you can use <ScrollView> With a layout or component in it.

Because it's the same component. You can either listen to route change by injecting the ActivatedRoute and reacting to changes of params and query params, or you can change the default RouteReuseStrategy, so that a component will be destroyed and re-rendered when the URL changes instead of re-used.

This Javascript function purports to show the difference between the Blob File API and the Data API to download a JSON file in the client browser:

/**_x000D_
 * Save a text as file using HTML <a> temporary element and Blob_x000D_
 * @author Loreto Parisi_x000D_
 */_x000D_
_x000D_
var saveAsFile = function(fileName, fileContents) {_x000D_
    if (typeof(Blob) != 'undefined') { // Alternative 1: using Blob_x000D_
        var textFileAsBlob = new Blob([fileContents], {type: 'text/plain'});_x000D_
        var downloadLink = document.createElement("a");_x000D_
        downloadLink.download = fileName;_x000D_
        if (window.webkitURL != null) {_x000D_
            downloadLink.href = window.webkitURL.createObjectURL(textFileAsBlob);_x000D_
        } else {_x000D_
            downloadLink.href = window.URL.createObjectURL(textFileAsBlob);_x000D_
            downloadLink.onclick = document.body.removeChild(event.target);_x000D_
            downloadLink.style.display = "none";_x000D_
            document.body.appendChild(downloadLink);_x000D_
        }_x000D_
        downloadLink.click();_x000D_
    } else { // Alternative 2: using Data_x000D_
        var pp = document.createElement('a');_x000D_
        pp.setAttribute('href', 'data:text/plain;charset=utf-8,' +_x000D_
            encodeURIComponent(fileContents));_x000D_
        pp.setAttribute('download', fileName);_x000D_
        pp.onclick = document.body.removeChild(event.target);_x000D_
        pp.click();_x000D_
    }_x000D_
} // saveAsFile_x000D_
_x000D_
/* Example */_x000D_
var jsonObject = {"name": "John", "age": 30, "car": null};_x000D_
saveAsFile('out.json', JSON.stringify(jsonObject, null, 2));

The function is called like saveAsFile('out.json', jsonString);. It will create a ByteStream immediately recognized by the browser that will download the generated file directly using the File API URL.createObjectURL.

In the else, it is possible to see the same result obtained via the href element plus the Data API, but this has several limitations that the Blob API has not.
