The simpliest solution (in case you are using fastcgi+nignx) is what itgorilla commented:

Thank you for this great question. My fastcgi was not passing the REMOTE_ADDR meta key. I added the line below in the nginx.conf and fixed the problem: fastcgi_param REMOTE_ADDR $remote_addr; – itgorilla

Ps: I added this answer just to make his solution more visible.

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.

developer.android.com has nice example code for this: https://developer.android.com/guide/topics/providers/document-provider.html

A condensed version to just extract the file name (assuming "this" is an Activity):

public String getFileName(Uri uri) {
  String result = null;
  if (uri.getScheme().equals("content")) {
    Cursor cursor = getContentResolver().query(uri, null, null, null, null);
    try {
      if (cursor != null && cursor.moveToFirst()) {
        result = cursor.getString(cursor.getColumnIndex(OpenableColumns.DISPLAY_NAME));
      }
    } finally {
      cursor.close();
    }
  }
  if (result == null) {
    result = uri.getPath();
    int cut = result.lastIndexOf('/');
    if (cut != -1) {
      result = result.substring(cut + 1);
    }
  }
  return result;
}

The error means exactly what it says.

Even if you could work around this, trust me, you don't want to. The number of confusing bugs that could be introduced is staggering and scary, not to mention the fact that your performance will likely go down the tubes.

Don't work around this. Fix your data model.

EDIT: I've seen that a number of people are downvoting this question. That's fine, I suppose, but keep in mind that the OP asked about mapping a table without a primary key, not a view. The answer is still the same. Working around the EF's need to have a PK on tables is a bad idea from the standpoint of manageability, data integrity, and performance.

Some have commented that they do not have the ability to fix the underlying data model because they're mapping to a third-party application. That is not a good idea, as the model can change out from under you. Arguably, in that case, you would want to map to a view, which, again, is not what the OP asked.

The answer is of course to create a SimpleDateFormat object and use it to parse Strings to Date and to format Dates to Strings. If you've tried SimpleDateFormat and it didn't work, then please show your code and any errors you may receive.

Addendum: "mm" in the format String is not the same as "MM". Use MM for months and mm for minutes. Also, yyyyy is not the same as yyyy. e.g.,:

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

public class FormateDate {

    public static void main(String[] args) throws ParseException {
        String date_s = "2011-01-18 00:00:00.0";

        // *** note that it's "yyyy-MM-dd hh:mm:ss" not "yyyy-mm-dd hh:mm:ss"  
        SimpleDateFormat dt = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
        Date date = dt.parse(date_s);

        // *** same for the format String below
        SimpleDateFormat dt1 = new SimpleDateFormat("yyyy-MM-dd");
        System.out.println(dt1.format(date));
    }

}

STR_TO_DATE allows you to do this, and it has a format argument.

I stumbled across Android XRef the other day and found it useful, especially since it is backed by OpenGrok which offers insanely awesome and blindingly fast search.

PASS A HASH INTO THE METHOD AND POPULATE IT......

public void buildResponse(String data, Map response);

Here is the complete solution for directly integrating a report-viewer control (as well as any asp.net server side control) in an MVC .aspx view, which will also work on a report with multiple pages (unlike Adrian Toman's answer) and with AsyncRendering set to true, (based on "Pro ASP.NET MVC Framework" by Steve Sanderson).

What one needs to do is basically:

1. Add a form with runat = "server"

2. Add the control, (for report-viewer controls it can also sometimes work even with AsyncRendering="True" but not always, so check in your specific case)

3. Add server side scripting by using script tags with runat = "server"

4. Override the Page_Init event with the code shown below, to enable the use of PostBack and Viewstate

Here is a demonstration:

<form ID="form1" runat="server">
    <rsweb:ReportViewer ID="ReportViewer1" runat="server" />
</form>
<script runat="server">
    protected void Page_Init(object sender, EventArgs e)
    {
        Context.Handler = Page;
    }
    //Other code needed for the report viewer here        
</script>

It is of course recommended to fully utilize the MVC approach, by preparing all needed data in the controller, and then passing it to the view via the ViewModel.

This will allow reuse of the View!

However this is only said for data this is needed for every post back, or even if they are required only for initialization if it is not data intensive, and the data also has not to be dependent on the PostBack and ViewState values.

However even data intensive can sometimes be encapsulated into a lambda expression and then passed to the view to be called there.

A couple of notes though:

• By doing this the view essentially turns into a web form with all it's drawbacks, (i.e. Postbacks, and the possibility of non Asp.NET controls getting overriden)
• The hack of overriding Page_Init is undocumented, and it is subject to change at any time

From the docs:

str.split([sep[, maxsplit]])

Return a list of the words in the string, using sep as the delimiter string. If maxsplit is given, at most maxsplit splits are done (thus, the list will have at most maxsplit+1 elements).

s.split('mango', 1)[1]

 public static void main(String args[])
 {
 System.out.println(SumofAll(12,13,14,15));//Insert your number here.
   {
      public static int SumofAll(int...sum)//Call this method in main method.
          int total=0;//Declare a variable which will hold the total value.
            for(int x:sum)
          {
           total+=sum;
           }
  return total;//And return the total variable.
    }
 }

How this works?

Example: http://jsfiddle.net/953Yj/

<div class="center">
    Lorem ipsum
</div>

.center{
    position:absolute;
    height: X px;
    width: Y px;
    left:50%;
    top:50%;
    margin-top:- X/2 px;
    margin-left:- Y/2 px;
}

• X would your your height.
• Y would be your width.

To position the div vertically and horizontally, divide X and Y by 2.

You might have had Power Tool installed.

Updated for Swift 3 and above:

//1. Create the alert controller.
let alert = UIAlertController(title: "Some Title", message: "Enter a text", preferredStyle: .alert)

//2. Add the text field. You can configure it however you need.
alert.addTextField { (textField) in
    textField.text = "Some default text"
}

// 3. Grab the value from the text field, and print it when the user clicks OK.
alert.addAction(UIAlertAction(title: "OK", style: .default, handler: { [weak alert] (_) in
    let textField = alert.textFields![0] // Force unwrapping because we know it exists.
    print("Text field: \(textField.text)")
}))

// 4. Present the alert.
self.present(alert, animated: true, completion: nil)

Swift 2.x

Assuming you want an action alert on iOS:

//1. Create the alert controller.            
var alert = UIAlertController(title: "Some Title", message: "Enter a text", preferredStyle: .Alert)

//2. Add the text field. You can configure it however you need.
alert.addTextFieldWithConfigurationHandler({ (textField) -> Void in
    textField.text = "Some default text."
})

//3. Grab the value from the text field, and print it when the user clicks OK. 
alert.addAction(UIAlertAction(title: "OK", style: .Default, handler: { [weak alert] (action) -> Void in
    let textField = alert.textFields![0] as UITextField
    println("Text field: \(textField.text)")
}))

// 4. Present the alert.
self.presentViewController(alert, animated: true, completion: nil)

Try compiling your .NET assembly with the option --staticlink:"Namespace.Assembly" . This forces the compiler to pull in all the dependencies at compile time. If it comes across a dependency that's not referenced it will give a warning or error message usually with the name of that assembly.

Namespace.Assembly is the assembly you suspect as having the dependency problem. Typically just statically linking this assembly will reference all dependencies transitively.

Using the new nested query syntax

with q(name, id, parent_id, parent_name) as (

As the whole thing is mixing up let's look at it function and code to simulate what it means consicely

The only way to get a row is via primary key

getRow(pk: PrimaryKey): Row

Primary key data structure can be this:

// If you decide your primary key is just the partition key.
class PrimaryKey(partitionKey: String)

// and in thids case
getRow(somePartitionKey): Row

However you can decide your primary key is partition key + sort key in this case:

// if you decide your primary key is partition key + sort key
class PrimaryKey(partitionKey: String, sortKey: String)

getRow(partitionKey, sortKey): Row
getMultipleRows(partitionKey): Row[]

So the bottom line:

1. Decided that your primary key is partition key only? get single row by partition key.

2. Decided that your primary key is partition key + sort key? 2.1 Get single row by (partition key, sort key) or get range of rows by (partition key)

In either way you get a single row by primary key the only question is if you defined that primary key to be partition key only or partition key + sort key

Building blocks are:

1. Table
2. Item
3. KV Attribute.

Think of Item as a row and of KV Attribute as cells in that row.

1. You can get an item (a row) by primary key.
2. You can get multiple items (multiple rows) by specifying (HashKey, RangeKeyQuery)

You can do (2) only if you decided that your PK is composed of (HashKey, SortKey).

More visually as its complex, the way I see it:

So what is happening above. Notice the following observations. As we said our data belongs to (Table, Item, KVAttribute). Then Every Item has a primary key. Now the way you compose that primary key is meaningful into how you can access the data.

If you decide that your PrimaryKey is simply a hash key then great you can get a single item out of it. If you decide however that your primary key is hashKey + SortKey then you could also do a range query on your primary key because you will get your items by (HashKey + SomeRangeFunction(on range key)). So you can get multiple items with your primary key query.

Note: I did not refer to secondary indexes.

Java is a server side language, whereas javascript is a client side language. Both cannot communicate. If you have setup some server side script using Java you could use AJAX on the client in order to send an asynchronous request to it and thus invoke any possible Java functions. For example if you use jQuery as js framework you may take a look at the $.ajax() method. Or if you wanted to do it using plain javascript, here's a tutorial.

The DateTime should always be internally in the "american" (Gregorian) calendar. So if you do

var str = dateTime.ToString(@"yyyy/MM/dd hh:mm:ss tt", new CultureInfo("en-US"));

you should get what you want in many less lines.

If the required properties need to set in system then there is no option than -D But if you need those properties while bootstrapping an application then loading properties through the properties files is a best option. It will not require to change build for a single property.

If in addition you want to pipe the output to a separate file, you can do:

On a Sun JVM:

-Xloggc:C:\whereever\jvm.log -verbose:gc -XX:+PrintGCDateStamps

ON an IBM JVM:

-Xverbosegclog:C:\whereever\jvm.log 

I think by combining .children() with $(this) will return the children of the selected item only

consider the following:

$("div li").click(function() {
$(this).children().css('background','red');
});

this will change the background of the clicked li only

Why do you need to do this in one monster-regex? You can use actual code to implement some of these rules, and doing so would be much easier to modify if those requirements change later.

For example:

if(/^[A-Z0-9\s]*$/)
    # sentence is all uppercase, so just fail out
    return 0;

# Carry on with matching uppercase terms

Any one looking for a swift solution

let url = NSURL(string: "http://www.apple.com/")
let request = NSMutableURLRequest(URL: url!)
request.HTTPBody = "company=Locassa&quality=AWESOME!".dataUsingEncoding(NSUTF8StringEncoding)

My idea:

public enum SomeKindOfEnum{
    ENUM_NAME("initialValue");

    private String value;

    SomeKindOfEnum(String value){
        this.value = value;
    }

    public boolean equalValue(String passedValue){
        return this.value.equals(passedValue);
    }
}

And if u want to check Value u write:

SomeKindOfEnum.ENUM_NAME.equalValue("initialValue")

Kinda looks nice for me :). Maybe somebody will find it useful.

You can solve the issue by clearing value of address in endpoint tag in web.config:

<endpoint address="" name="wsHttpEndpoint"  .......           />

You'll need to compile it using:

g++ inputfile.cpp -o outputbinary

The file you are referring has a missing #include <cstdlib> directive, if you also include that in your file, everything shall compile fine.

Use this - http://jgilfelt.github.io/android-actionbarstylegenerator/

Its an amazing tool that lets you customize your actionbar with a live preview.

I tried the earlier answers but always had problems with changing other colors like the tabs and letters and spent hours tweaking stuff. This tool helped me get my design done in just a couple of minutes.

All the best! :)

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.

You can also use http://schemas.android.com/apk/res-auto that would take care of it automatically. Use it like this:

xmlns:ads="http://schemas.android.com/apk/res-auto"

onkeyup worked for me. onkeypress doesn't trigger when pressing back space.

string = string.replace(/[\W_]/g, "_");

Try this:

tar -zxvf file.tar.gz

In win, download the py based latest numpy and Opencv from Unofficial Windows Binaries for Python Extension Packages and pip install its source in cmd. Later copy site-package folder from main py lib to venv lib.

How about making your app agnostic of the server's timezone?

Owing to any of these possible scenarios:

• You might not have control over the web/database server's timezone settings
• You might mess up and set the settings incorrectly
• There are so many settings as described in the other answers, and so many things to keep track of, that you might miss something
• An update on the server, or a software reset, or another admin, might unknowing reset the servers' timezone to the default - thus breaking your application

All of the above scenarios give rise to breaking of your application's time calculations. Thus it appears that the better approach is to make your application work independent of the server's timezone.

The idea is simply to always create dates in UTC before storing them into the database, and always re-create them from the stored values in UTC as well. This way, the time calculations won't ever be incorrect, because they're always in UTC. This can be achieved by explicity stating the DateTimeZone parameter when creating a PHP DateTime object.

On the other hand, the client side functionality can be configured to convert all dates/times received from the server to the client's timezone. Libraries like moment.js make this super easy to do.

For example, when storing a date in the database, instead of using the NOW() function of MySQL, create the timestamp string in UTC as follows:

// Storing dates
$date = new DateTime('now', new DateTimeZone('UTC'));
$sql = 'insert into table_name (date_column) values ("' . $date . '")';

// Retreiving dates
$sql = 'select date_column from table_name where condition';
$dateInUTC = new DateTime($date_string_from_db, new DateTimeZone('UTC'));

You can set the default timezone in PHP for all dates created, thus eliminating the need to initialize the DateTimeZone class every time you want to create a date.

startdate = moment().subtract(1, 'days').format('DD-MM-YYYY');

Embrace the future! Just to be complete, you can also do this the Python 3k way by using the print function:

from __future__ import print_function  # Py 2.6+; In Py 3k not needed

mylist = ['10', 12, '14']    # Note that 12 is an int

print(*mylist,sep='\n')

Prints:

10
12
14

Eventually, print as Python statement will go away... Might as well start to get used to it.

I tried the chosen answer, but found when I ran a shell script having it, the whole thing was getting printed to screen (similar to how jupyter notebooks print out everything in '''xx''' quotes) and there was an error message at end. It wasn't doing anything, but: scary. Then I realised while editing it that single-quotes can span multiple lines. So.. lets just assign the block to a variable.

x='
echo "these lines will all become comments."
echo "just make sure you don_t use single-quotes!"

ls -l
date

'

For MySql WorkBench, Please use below :

update emp as a
inner join department b on a.department_id=b.id
set a.department_name=b.name
where a.emp_id in (10,11,12); 

While correct that this will work:

TimeSpan time = TimeSpan.Parse("07:35");

And if you are using it for validation...

TimeSpan time;
if (!TimeSpan.TryParse("07:35", out time))
{
    // handle validation error
}

Consider that TimeSpan is primarily intended to work with elapsed time, rather than time-of-day. It will accept values larger than 24 hours, and will accept negative values also.

If you need to validate that the input string is a valid time-of-day (>= 00:00 and < 24:00), then you should consider this instead:

DateTime dt;
if (!DateTime.TryParseExact("07:35", "HH:mm", CultureInfo.InvariantCulture, 
                                              DateTimeStyles.None, out dt))
{
    // handle validation error
}
TimeSpan time = dt.TimeOfDay;

As an added benefit, this will also parse 12-hour formatted times when an AM or PM is included, as long as you provide the appropriate format string, such as "h:mm tt".

Too hard? Your TA is... well, the phrase would probably get me banned. Anyways, check to see if numb is negative. If it is then multiply numa by -1 and do numb = abs(numb). Then do the loop.

This assumes you know the position of the element in the ListView :

  View element = listView.getListAdapter().getView(position, null, null);

Then you should be able to call getLeft() and getTop() to determine the elements on screen position.

div {_x000D_
  white-space: nowrap;_x000D_
  overflow: hidden;_x000D_
}

<div>test that doesn't wrap</div>

Note: this only works on block elements. If you need to do this to table cells (for example) you need to put a div inside the table cell as table cells have display table-cell not block.

As of CSS3, this is supported for table cells as well.

You already have a lot of reading material, but if you can handle more, I recommend you learn about the evolution of python by reading the Python Enhancement Proposals, especially the "Finished" PEPs and the "Deferred, Abandoned, Withdrawn, and Rejected" PEPs.

By seeing how the language has changed, the decisions that were made and their rationales, you will absorb the philosophy of Python and understand how "idiomatic Python" comes about.

http://www.python.org/dev/peps/

The task gives you all the goodness of the task API:

• Adding continuations (Task.ContinueWith)
• Waiting for multiple tasks to complete (either all or any)
• Capturing errors in the task and interrogating them later
• Capturing cancellation (and allowing you to specify cancellation to start with)
• Potentially having a return value
• Using await in C# 5
• Better control over scheduling (if it's going to be long-running, say so when you create the task so the task scheduler can take that into account)

Note that in both cases you can make your code slightly simpler with method group conversions:

DataInThread = new Thread(ThreadProcedure);
// Or...
Task t = Task.Factory.StartNew(ThreadProcedure);

var Ihours = Math.floor(TotMin / 60);          

var Iminutes = TotMin % 60; var TotalTime = Ihours+":"+Iminutes+':00';

   $.ajax({
            url: ../..,
            cache: false,
            type: "POST",                
            data: JSON.stringify({objRoot: TotalTime}) ,
            dataType: 'json',
            contentType: "application/json; charset=utf-8",
            success: function (response) {

            },
            error: function (er) {
                console.log(er);
            }
        });

You can use maps with Map, like this:

var sayings = new Map();
sayings.set('dog', 'woof');
sayings.set('cat', 'meow');

Kurt's answer should be right, from my research, but when I tried it I had to do this to get it to actually work for me:

return RedirectToAction( "Main", new RouteValueDictionary( 
    new { controller = controllerName, action = "Main", Id = Id } ) );

If I didn't specify the controller and the action in the RouteValueDictionary it didn't work.

Also when coded like this, the first parameter (Action) seems to be ignored. So if you just specify the controller in the Dict, and expect the first parameter to specify the Action, it does not work either.

If you are coming along later, try Kurt's answer first, and if you still have issues try this one.

$(( ( RANDOM % 10 )  + 1 ))

EDIT. Changed brackets into parenthesis according to the comment. http://web.archive.org/web/20150206070451/http://islandlinux.org/howto/generate-random-numbers-bash-scripting

You can use int casting which allows the base specification.

int(b, 2)  # Convert a binary string to a decimal int.

Your url String needs variable markers for the map you pass to work, like:

String url = "https://app.example.com/hr/email?{email}";

Or you could explicitly code the query params into the String to begin with and not have to pass the map at all, like:

String url = "https://app.example.com/hr/[email protected]";

Here are the steps:

• Install the subclipse plugin (provides svn connectivity in eclipse) and connect to the repository. Instructions here: http://subclipse.tigris.org/install.html
• Go to File->New->Other->Under the SVN category, select Checkout Projects from SVN.
• Select your project's root folder and select checkout as a project in the workspace.

It seems you are checking the .project file into the source repository. I would suggest not checking in the .project file so users can have their own version of the file. Also, if you use the subclipse plugin it allows you to check out and configure a source folder as a java project. This process creates the correct .project for you(with the java nature),

Try any of the following solutions. I get errors with adb every now and then. And one of the following always works.

Solution 1
Open command prompt as administrator and enter

1. adb kill-server
2. adb start-server

Solution 2
Install drivers for your phone if you're not testing on emulator.

Solution 3
Open android sdk manager and install "Google USB Driver" from extras folder. (attached screenshot)

See the isDigit(char ch) method:

https://docs.oracle.com/javase/1.5.0/docs/api/java/lang/Character.html

and pass it to the first character of the String using the String.charAt() method.

Character.isDigit(myString.charAt(0));

It should be like this.

In your Component

computed: {
        ...mapGetters({
                nameFromStore: 'name'
            }),

           get(){
             return this.nameFromStore
           },
           set(newName){
             return newName
           } 
        }
    }

In your store

export const store = new Vuex.Store({
         state:{
             name : "Stackoverflow"
         },
         getters: {

Hi I'm also relatively new but I can give you basic help.

1. To switch to another branch use "Checkout". Just click on your branch and then on the button "checkout" at the top.

UPDATE 12.01.2016:

The bold line is the current branch.

You can also just double click a branch to use checkout.

2. Your first answer I think depends on the repository you use (like github or bitbucket). Maybe the "Show hosted repository"-Button can help you (Left panel, bottom, right button = database with cog)

And here some helpful links:

Easy Git Guide

Git-flow - Git branching model

Tips on branching with sourcetree

Git doesn't think in terms of file versions. A version in git is a snapshot of the entire tree.

Given this, what you really want is a tree that has the latest content of most files, but with the contents of one file the same as it was 5 commits ago. This will take the form of a new commit on top of the old ones, and the latest version of the tree will have what you want.

I don't know if there's a one-liner that will revert a single file to the contents of 5 commits ago, but the lo-fi solution should work: checkout master~5, copy the file somewhere else, checkout master, copy the file back, then commit.

Dir[File.join(__dir__, "/app/**/*.rb")].each do |file|
  require file
end

This will work recursively on your local machine and a remote (Like Heroku) which does not use relative paths.

For skipping memory limit and version error use the code below:

COMPOSER_MEMORY_LIMIT=-1 composer require <package-name> --ignore-platform-reqs

I was having the same problem. I ended up going into the subdirectory that was "not staged for commit" and adding, committing and pushing from there. after that, went up one level to master directory and was able to push correctly.

I think you want to specify

-H "Content-Type:text/xml"

with a colon, not an equals.

This solution works fine for all major browsers, except IE. So keep that in mind.

In this example, basicaly I use positioning, horizontal and vertical transform for the UI element to center it.

        .container {_x000D_
            /* set the the position to relative */_x000D_
            position: relative;_x000D_
            width: 30rem;_x000D_
            height: 20rem;_x000D_
            background-color: #2196F3;_x000D_
        }_x000D_
_x000D_
_x000D_
        .paragh {_x000D_
            /* set the the position to absolute */_x000D_
            position: absolute;_x000D_
            /* set the the position of the helper container into the middle of its space */_x000D_
            top: 50%;_x000D_
            left: 50%;_x000D_
            font-size: 30px;_x000D_
            /* make sure padding and margin do not disturb the calculation of the center point */_x000D_
            padding: 0;_x000D_
            margin: 0;_x000D_
            /* using centers for the transform */_x000D_
            transform-origin: center center;_x000D_
            /* calling calc() function for the calculation to move left and up the element from the center point */_x000D_
            transform: translateX(calc((100% / 2) * (-1))) translateY(calc((100% / 2) * (-1)));_x000D_
        }

<div class="container">_x000D_
    <p class="paragh">Text</p>_x000D_
</div>

I hope this help.

Use

scanf("%d", &array[0]);

and use == for comparision instead of =

Please mind that the accepted answers work only if the lambda is given on a separate line. If you pass it in as an argument to a function and would like to retrieve the code of the lambda as object, the problem gets a bit tricky since inspect will give you the whole line.

For example, consider a file test.py:

import inspect

def main():
    x, f = 3, lambda a: a + 1
    print(inspect.getsource(f))

if __name__ == "__main__":
    main()

Executing it gives you (mind the indention!):

    x, f = 3, lambda a: a + 1

To retrieve the source code of the lambda, your best bet, in my opinion, is to re-parse the whole source file (by using f.__code__.co_filename) and match the lambda AST node by the line number and its context.

We had to do precisely that in our design-by-contract library icontract since we had to parse the lambda functions we pass in as arguments to decorators. It is too much code to paste here, so have a look at the implementation of this function.

Two questions we must ask ourselves while doing such operations are:

1. What's the amount of memory used to perform it?
2. Is the memory consumption increasing drastically with the file size?

Solutions like require('fs').readFileSync() loads the whole file into memory. That means that the amount of memory required to perform operations will be almost equivalent to the file size. We should avoid these for anything larger than 50mbs

We can easily track the amount of memory used by a function by placing these lines of code after the function invocation :

    const used = process.memoryUsage().heapUsed / 1024 / 1024;
    console.log(
      `The script uses approximately ${Math.round(used * 100) / 100} MB`
    );

Right now the best way to read particular lines from a large file is using node's readline. The documentation has an amazing examples.

Although we don't need any third-party module to do it. But, If you are writing an enterprise code, you have to handle lots of edge cases. I had to write a very lightweight module called Apick File Storage to handle all those edge cases.

Apick File Storage module : https://www.npmjs.com/package/apickfs Documentation : https://github.com/apickjs/apickFS#readme

Example file: https://1drv.ms/t/s!AtkMCsWInsSZiGptXYAFjalXOpUx

Example : Install module

npm i apickfs

// import module
const apickFileStorage = require('apickfs');

//invoke readByLineNumbers() method
apickFileStorage
  .readByLineNumbers(path.join(__dirname), 'big.txt', [163845])
  .then(d => {
    console.log(d);
  })
  .catch(e => {
    console.log(e);
  });

This method was successfully tested with up to 4 GB dense files.

big.text is a dense text file with 163,845 lines and is of 124 Mb. The script to read 10 different lines from this file uses approximately just 4.63 MB Memory only. And it parses valid JSON to Objects or Arrays for free. Awesome!!

We can read a single line of the file or hundreds of lines of the file with very little memory consumption.

System.setProperty("gate.home", "/some/directory");

• The System Properties tutorial.
• Class doc for System.setProperty( String key , String value ).

There's no problem with using a localhost url for Dev work - obviously it needs to be changed when it comes to production.

You need to go here: https://developers.google.com/accounts/docs/OAuth2 and then follow the link for the API Console - link's in the Basic Steps section. When you've filled out the new application form you'll be asked to provide a redirect Url. Put in the page you want to go to once access has been granted.

When forming the Google oAuth Url - you need to include the redirect url - it has to be an exact match or you'll have problems. It also needs to be UrlEncoded.

    protected override void OnLoad(EventArgs e) {
        base.OnLoad(e);

You're calling both wait and notifyAll without using a synchronized block. In both cases the calling thread must own the lock on the monitor you call the method on.

From the docs for notify (wait and notifyAll have similar documentation but refer to notify for the fullest description):

This method should only be called by a thread that is the owner of this object's monitor. A thread becomes the owner of the object's monitor in one of three ways:

• By executing a synchronized instance method of that object.
• By executing the body of a synchronized statement that synchronizes on the object.
• For objects of type Class, by executing a synchronized static method of that class.

Only one thread at a time can own an object's monitor.

Only one thread will be able to actually exit wait at a time after notifyAll as they'll all have to acquire the same monitor again - but all will have been notified, so as soon as the first one then exits the synchronized block, the next will acquire the lock etc.

It was requested that I add this functionality to the stackoverflow R package. Given that it is a tinyverse package (and can't depend on third party packages), here is what I came up with:

#' Bulk import data files 
#' 
#' Read in each file at a path and then unnest them. Defaults to csv format.
#' 
#' @param path        a character vector of full path names
#' @param pattern     an optional \link[=regex]{regular expression}. Only file names which match the regular expression will be returned.
#' @param reader      a function that can read data from a file name.
#' @param ...         optional arguments to pass to the reader function (eg \code{stringsAsFactors}).
#' @param reducer     a function to unnest the individual data files. Use I to retain the nested structure. 
#' @param recursive     logical. Should the listing recurse into directories?

read.directory <- function(path='.', pattern=NULL, reader=read.csv, ..., 
                           reducer=function(dfs) do.call(rbind.data.frame, dfs), recursive=FALSE) {
  files <- list.files(path, pattern, full.names = TRUE, recursive = recursive)

  reducer(lapply(files, reader, ...))
}

By parameterizing the reader and reducer function, people can use data.table or dplyr if they so choose, or just use the base R functions that are fine for smaller data sets.

Following Peter Hauge's comment, upon running docker network ls I saw (among other lines) the following:

NETWORK ID          NAME                                    DRIVER              SCOPE
dc6a83d13f44        bridge                                  bridge              local
ea98225c7754        docker_gwbridge                         bridge              local
107dcd8aa889        host                                    host                local

The line with NAME and DRIVER as both host seems to be what he is referring to with "networks already created on your host". So, following https://gist.github.com/bastman/5b57ddb3c11942094f8d0a97d461b430, I ran the command

docker network rm $(docker network ls | grep "bridge" | awk '/ / { print $1 }')

Now docker-compose up works (although newnym.py produces an error).

I think all of the answers here cover the core of what the lambda function does in the context of sorted() quite nicely, however I still feel like a description that leads to an intuitive understanding is lacking, so here is my two cents.

For the sake of completeness, I'll state the obvious up front: sorted() returns a list of sorted elements and if we want to sort in a particular way or if we want to sort a complex list of elements (e.g. nested lists or a list of tuples) we can invoke the key argument.

For me, the intuitive understanding of the key argument, why it has to be callable, and the use of lambda as the (anonymous) callable function to accomplish this comes in two parts.

1. Using lamba ultimately means you don't have to write (define) an entire function, like the one sblom provided an example of. Lambda functions are created, used, and immediately destroyed - so they don't funk up your code with more code that will only ever be used once. This, as I understand it, is the core utility of the lambda function and its applications for such roles are broad. Its syntax is purely by convention, which is in essence the nature of programmatic syntax in general. Learn the syntax and be done with it.

Lambda syntax is as follows:

lambda input_variable(s): tasty one liner

e.g.

In [1]: f00 = lambda x: x/2

In [2]: f00(10)
Out[2]: 5.0

In [3]: (lambda x: x/2)(10)
Out[3]: 5.0

In [4]: (lambda x, y: x / y)(10, 2)
Out[4]: 5.0

In [5]: (lambda: 'amazing lambda')() # func with no args!
Out[5]: 'amazing lambda'

2. The idea behind the key argument is that it should take in a set of instructions that will essentially point the 'sorted()' function at those list elements which should used to sort by. When it says key=, what it really means is: As I iterate through the list one element at a time (i.e. for e in list), I'm going to pass the current element to the function I provide in the key argument and use that to create a transformed list which will inform me on the order of final sorted list.

Check it out:

mylist = [3,6,3,2,4,8,23]
sorted(mylist, key=WhatToSortBy)

Base example:

sorted(mylist)

[2, 3, 3, 4, 6, 8, 23] # all numbers are in order from small to large.

Example 1:

mylist = [3,6,3,2,4,8,23]
sorted(mylist, key=lambda x: x%2==0)

[3, 3, 23, 6, 2, 4, 8] # Does this sorted result make intuitive sense to you?

Notice that my lambda function told sorted to check if (e) was even or odd before sorting.

BUT WAIT! You may (or perhaps should) be wondering two things - first, why are my odds coming before my evens (since my key value seems to be telling my sorted function to prioritize evens by using the mod operator in x%2==0). Second, why are my evens out of order? 2 comes before 6 right? By analyzing this result, we'll learn something deeper about how the sorted() 'key' argument works, especially in conjunction with the anonymous lambda function.

Firstly, you'll notice that while the odds come before the evens, the evens themselves are not sorted. Why is this?? Lets read the docs:

Key Functions Starting with Python 2.4, both list.sort() and sorted() added a key parameter to specify a function to be called on each list element prior to making comparisons.

We have to do a little bit of reading between the lines here, but what this tells us is that the sort function is only called once, and if we specify the key argument, then we sort by the value that key function points us to.

So what does the example using a modulo return? A boolean value: True == 1, False == 0. So how does sorted deal with this key? It basically transforms the original list to a sequence of 1s and 0s.

[3,6,3,2,4,8,23] becomes [0,1,0,1,1,1,0]

Now we're getting somewhere. What do you get when you sort the transformed list?

[0,0,0,1,1,1,1]

Okay, so now we know why the odds come before the evens. But the next question is: Why does the 6 still come before the 2 in my final list? Well that's easy - its because sorting only happens once! i.e. Those 1s still represent the original list values, which are in their original positions relative to each other. Since sorting only happens once, and we don't call any kind of sort function to order the original even values from low to high, those values remain in their original order relative to one another.

The final question is then this: How do I think conceptually about how the order of my boolean values get transformed back in to the original values when I print out the final sorted list?

Sorted() is a built-in method that (fun fact) uses a hybrid sorting algorithm called Timsort that combines aspects of merge sort and insertion sort. It seems clear to me that when you call it, there is a mechanic that holds these values in memory and bundles them with their boolean identity (mask) determined by (...!) the lambda function. The order is determined by their boolean identity calculated from the lambda function, but keep in mind that these sublists (of one's and zeros) are not themselves sorted by their original values. Hence, the final list, while organized by Odds and Evens, is not sorted by sublist (the evens in this case are out of order). The fact that the odds are ordered is because they were already in order by coincidence in the original list. The takeaway from all this is that when lambda does that transformation, the original order of the sublists are retained.

So how does this all relate back to the original question, and more importantly, our intuition on how we should implement sorted() with its key argument and lambda?

That lambda function can be thought of as a pointer that points to the values we need to sort by, whether its a pointer mapping a value to its boolean transformed by the lambda function, or if its a particular element in a nested list, tuple, dict, etc., again determined by the lambda function.

Lets try and predict what happens when I run the following code.

mylist = [(3, 5, 8), (6, 2, 8), ( 2, 9, 4), (6, 8, 5)]
sorted(mylist, key=lambda x: x[1])

My sorted call obviously says, "Please sort this list". The key argument makes that a little more specific by saying, for each element (x) in mylist, return index 1 of that element, then sort all of the elements of the original list 'mylist' by the sorted order of the list calculated by the lambda function. Since we have a list of tuples, we can return an indexed element from that tuple. So we get:

[(6, 2, 8), (3, 5, 8), (6, 8, 5), (2, 9, 4)]

Run that code, and you'll find that this is the order. Try indexing a list of integers and you'll find that the code breaks.

This was a long winded explanation, but I hope this helps to 'sort' your intuition on the use of lambda functions as the key argument in sorted() and beyond.

SELECT created
  FROM dba_objects
 WHERE object_name = <<your table name>>
   AND owner = <<owner of the table>>
   AND object_type = 'TABLE'

will tell you when a table was created (if you don't have access to DBA_OBJECTS, you could use ALL_OBJECTS instead assuming you have SELECT privileges on the table).

The general answer to getting timestamps from a row, though, is that you can only get that data if you have added columns to track that information (assuming, of course, that your application populates the columns as well). There are various special cases, however. If the DML happened relatively recently (most likely in the last couple hours), you should be able to get the timestamps from a flashback query. If the DML happened in the last few days (or however long you keep your archived logs), you could use LogMiner to extract the timestamps but that is going to be a very expensive operation particularly if you're getting timestamps for many rows. If you build the table with ROWDEPENDENCIES enabled (not the default), you can use

SELECT scn_to_timestamp( ora_rowscn ) last_modified_date,
       ora_rowscn last_modified_scn,
       <<other columns>>
  FROM <<your table>>

to get the last modification date and SCN (system change number) for the row. By default, though, without ROWDEPENDENCIES, the SCN is only at the block level. The SCN_TO_TIMESTAMP function also isn't going to be able to map SCN's to timestamps forever.

I prefer this usage:

    public static class StringExtensions
    {
        /// <summary>
        /// Check if string is Base64
        /// </summary>
        /// <param name="base64"></param>
        /// <returns></returns>
        public static bool IsBase64String(this string base64)
        {
            //https://stackoverflow.com/questions/6309379/how-to-check-for-a-valid-base64-encoded-string
            Span<byte> buffer = new Span<byte>(new byte[base64.Length]);
            return Convert.TryFromBase64String(base64, buffer, out int _);
        }
    }

Then usage

if(myStr.IsBase64String()){

    ...

}

You can use verbatim literals:

const string test = @"Test
123
456
";

But the indentation of the 1st line is tricky/ugly.

In Python 3, urllib2 was replaced by two in-built modules named urllib.request and urllib.error

Adapted from source

So replace this:

import urllib2

With this:

import urllib.request as urllib2

to remove the border , juste using css like this :

td {
 border-style : hidden!important;
}

isEmpty will do as you think it will, if string == "", it'll return true. Some of the other answers point to a situation where you have an optional string.

PLEASE use Optional Chaining!!!!

If the string is not nil, isEmpty will be used, otherwise it will not.

Below, the optionalString will NOT be set because the string is nil

let optionalString: String? = nil
if optionalString?.isEmpty == true {
     optionalString = "Lorem ipsum dolor sit amet"
}

Obviously you wouldn't use the above code. The gains come from JSON parsing or other such situations where you either have a value or not. This guarantees code will be run if there is a value.

A simple way to think about it is using even plainer English

If Bool1 And Bool2 Then
If [both are true] Then


If Bool1 AndAlso Bool2 Then
If [first is true then evaluate the second] Then

The values() method returns a QuerySet containing dictionaries:

<QuerySet [{'comment_id': 1}, {'comment_id': 2}]>

The values_list() method returns a QuerySet containing tuples:

<QuerySet [(1,), (2,)]>

If you are using values_list() with a single field, you can use flat=True to return a QuerySet of single values instead of 1-tuples:

<QuerySet [1, 2]>

In a git bash session, you can add a script to ~/.profile or ~/.bashrc (with ~ being usually set to %USERPROFILE%), in order for said session to launch automatically the ssh-agent. If the file doesn't exist, just create it.

This is what GitHub describes in "Working with SSH key passphrases".

The "Auto-launching ssh-agent on Git for Windows" section of that article has a robust script that checks if the agent is running or not. Below is just a snippet, see the GitHub article for the full solution.

# This is just a snippet. See the article above.
if ! agent_is_running; then
    agent_start
    ssh-add
elif ! agent_has_keys; then
    ssh-add
fi

Other Resources:

"Getting ssh-agent to work with git run from windows command shell" has a similar script, but I'd refer to the GitHub article above primarily, which is more robust and up to date.

//Resolved
const fetchPromise1 = fetch(url);
    fetchPromise1.then(response => {
      console.log(response);
    });

const fetchPromise = fetch(url);
console.log(fetchPromise);

As others already replied, it's late to write unit tests, but not too late. The question is whether your code is testable or not. Indeed, it's not easy to put existing code under test, there is even a book about this: Working Effectively with Legacy Code (see key points or precursor PDF).

Now writing the unit tests or not is your call. You just need to be aware that it could be a tedious task. You might tackle this to learn unit-testing or consider writing acceptance (end-to-end) tests first, and start writing unit tests when you'll change the code or add new feature to the project.

To get the list of fields for which there are multiple records, you can use..

select field1,field2,field3, count(*)
  from table_name
  group by field1,field2,field3
  having count(*) > 1

Check this link for more information on how to delete the rows.

http://support.microsoft.com/kb/139444

There should be a criterion for deciding how you define "first rows" before you use the approach in the link above. Based on that you'll need to use an order by clause and a sub query if needed. If you can post some sample data, it would really help.

Based on other answers, there are basically two approaches: subclassing HashMap or wrapping String. The first one requires a little more work. In fact, if you want to do it correctly, you must override almost all methods (containsKey, entrySet, get, put, putAll and remove).

Anyway, it has a problem. If you want to avoid future problems, you must specify a Locale in String case operations. So you would create new methods (get(String, Locale), ...). Everything is easier and clearer wrapping String:

public final class CaseInsensitiveString {

    private final String s;

    public CaseInsensitiveString(String s, Locale locale) {
        this.s = s.toUpperCase(locale);
    }

    // equals, hashCode & toString, no need for memoizing hashCode
}

And well, about your worries on performance: premature optimization is the root of all evil :)

Here is the complete programme please check this

static void Main(string[] args)
{
    List<string> li = new List<string>();
    li.Add("Ram");
    li.Add("shyam");
    li.Add("Ram");
    li.Add("Kumar");
    li.Add("Kumar");

    var x = from obj in li group obj by obj into g select new { Name = g.Key, Duplicatecount = g.Count() };
    foreach(var m in x)
    {
        Console.WriteLine(m.Name + "--" + m.Duplicatecount);
    }
    Console.ReadLine();
}        

You are touching multiple issues here:

1) A stack trace should never be visibile to end users (for user experience and security purposes)

Yes, it should be accessible to diagnose problems of end-users, but end-user should not see them for two reasons:

• They are very obscure and unreadable, the application will look very user-unfriendly.
• Showing a stack trace to end-user might introduce a potential security risk. Correct me if I'm wrong, PHP actually prints function parameters in stack trace - brilliant, but very dangerous - if you would you get exception while connecting to the database, what are you likely to in the stacktrace?

2) Generating a stack trace is a relatively expensive process (though unlikely to be an issue in most 'exception'al circumstances)

Generating a stack trace happens when the exception is being created/thrown (that's why throwing an exception comes with a price), printing is not that expensive. In fact you can override Throwable#fillInStackTrace() in your custom exception effectively making throwing an exception almost as cheap as a simple GOTO statement.

3) Many logging frameworks will print the stack trace for you (ours does not and no, we can't change it easily)

Very good point. The main issue here is: if the framework logs the exception for you, do nothing (but make sure it does!) If you want to log the exception yourself, use logging framework like Logback or Log4J, to not put them on the raw console because it is very hard to control it.

With logging framework you can easily redirect stack traces to file, console or even send them to a specified e-mail address. With hardcoded printStackTrace() you have to live with the sysout.

4) Printing the stack trace does not constitute error handling. It should be combined with other information logging and exception handling.

Again: log SQLException correctly (with the full stack trace, using logging framework) and show nice: "Sorry, we are currently not able to process your request" message. Do you really think the user is interested in the reasons? Have you seen StackOverflow error screen? It's very humorous, but does not reveal any details. However it ensures the user that the problem will be investigated.

But he will call you immediately and you need to be able to diagnose the problem. So you need both: proper exception logging and user-friendly messages.

To wrap things up: always log exceptions (preferably using logging framework), but do not expose them to the end-user. Think carefully and about error-messages in your GUI, show stack traces only in development mode.

If you are using windows 8 or later:

1. download and install the jdk or jre with all the default settings and options.
2. Then download and install eclipse.

Everything should work fine. I don't know if it works exactly the same for other OS, but you don't have to set the PATH manually in Windows 8 or later.

One example of rawQuery - db.rawQuery("select * from table where column = ?",new String[]{"data"});

The listings package is quite nice and very flexible (e.g. different sizes for comments and code).

FluentWait throws a NoSuchElementException is case of the confusion

org.openqa.selenium.NoSuchElementException;     

with

java.util.NoSuchElementException

in

.ignoring(NoSuchElementException.class)

Do it using JS. Grab the class of the error message, and change it's content for whereever it appears.

var myClasses = document.getElementsByClassName("wpcf7-not-valid-tip");

for (var i = 0; i < myClasses.length; i++) {
    myClasses[i].innerHTML = "Bitte füllen Sie das Pflichtfeld aus.";
}

Use npm install packageName --save this will add package in dependencies, if you use npm install packageName --save-dev then it devDependencies.

npm install packageName --save-dev should be used for adding packages for development purpose. Like adding TDD packages (Chai, mocha, etc). Which are used in development and not in production.

With :after and :before you can do that.

HTML:

<div class="a"> </div>
<div class="b"> </div>
<div class="c"> </div>

CSS:

div {
    height: 100px;
    position: relative;
}
.a {
    background: #9C9E9F;
}
.b {
    background: linear-gradient(to right, #9c9e9f, #f6f6f6);
}
.a:after, .c:before, .c:after {
    content: '';
    width: 50%;
    height: 100%;
    top: 0;
    right: 0;
    display: block;
    position: absolute;
}
.a:after {
    background: #f6f6f6;    
}
.c:before {
    background: #9c9e9f;
    left: 0;
}
.c:after {
    background: #33CCFF;
    right: 0;
    height: 80%;
}

And a demo.

You can use b character in front of a string literal:

import hashlib
print(hashlib.md5(b"Hello MD5").hexdigest())
print(hashlib.md5("Hello MD5".encode('utf-8')).hexdigest())

Out:

e5dadf6524624f79c3127e247f04b548
e5dadf6524624f79c3127e247f04b548

I could not get the previous answer to work. I did the following to get the index of the tab by name:

var index = $('#tabs a[href="#simple-tab-2"]').parent().index();
$('#tabs').tabs('select', index);

WinSCP can be called from batch file:

"C:\Program Files\WinSCP\WinSCP.exe" /console

Example commands:

option batch on 
option confirm off  
option transfer binary 
open sftp://username@hostname:port -hostkey="ssh-rsa " 

First of all

1. You don't need any special changes in the structure. I mean: html input tags.

<input accept="image/*" name="file" ng-value="fileToUpload"_x000D_
       value="{{fileToUpload}}" file-model="fileToUpload"_x000D_
       set-file-data="fileToUpload = value;" _x000D_
       type="file" id="my_file" />

1.2 create own directive,

.directive("fileModel",function() {_x000D_
 return {_x000D_
  restrict: 'EA',_x000D_
  scope: {_x000D_
   setFileData: "&"_x000D_
  },_x000D_
  link: function(scope, ele, attrs) {_x000D_
   ele.on('change', function() {_x000D_
    scope.$apply(function() {_x000D_
     var val = ele[0].files[0];_x000D_
     scope.setFileData({ value: val });_x000D_
    });_x000D_
   });_x000D_
  }_x000D_
 }_x000D_
})

2. In module with $httpProvider add dependency like ( Accept, Content-Type etc) with multipart/form-data. (Suggestion would be, accept response in json format) For e.g:

$httpProvider.defaults.headers.post['Accept'] = 'application/json, text/javascript'; $httpProvider.defaults.headers.post['Content-Type'] = 'multipart/form-data; charset=utf-8';

3. Then create separate function in controller to handle form submit call. like for e.g below code:

4. In service function handle "responseType" param purposely so that server should not throw "byteerror".

5. transformRequest, to modify request format with attached identity.

6. withCredentials : false, for HTTP authentication information.

in controller:_x000D_
_x000D_
  // code this accordingly, so that your file object _x000D_
  // will be picked up in service call below._x000D_
  fileUpload.uploadFileToUrl(file); _x000D_
_x000D_
_x000D_
in service:_x000D_
_x000D_
  .service('fileUpload', ['$http', 'ajaxService',_x000D_
    function($http, ajaxService) {_x000D_
_x000D_
      this.uploadFileToUrl = function(data) {_x000D_
        var data = {}; //file object _x000D_
_x000D_
        var fd = new FormData();_x000D_
        fd.append('file', data.file);_x000D_
_x000D_
        $http.post("endpoint server path to whom sending file", fd, {_x000D_
            withCredentials: false,_x000D_
            headers: {_x000D_
              'Content-Type': undefined_x000D_
            },_x000D_
            transformRequest: angular.identity,_x000D_
            params: {_x000D_
              fd_x000D_
            },_x000D_
            responseType: "arraybuffer"_x000D_
          })_x000D_
          .then(function(response) {_x000D_
            var data = response.data;_x000D_
            var status = response.status;_x000D_
            console.log(data);_x000D_

This error comes when there is error in your query syntax check field names table name, mean check your query syntax.

You can do so from within vim and use its own windows or tabs.

One way to go is to utilize the built-in file explorer; activate it via :Explore, or :Texplore for a tabbed interface (which I find most comfortable).

:Texplore (and :Sexplore) will also guard you from accidentally exiting the current buffer (editor) on :q once you're inside the explorer.

To toggle between open tabs when using tab pages use gt or gT (next tab and previous tab, respectively).

See also Using tab pages on the vim wiki.

Sometimes Xcode could not control over correctly cell outlet connection.

Somehow my current cell’s label/button has connected another cell I just remove those and error goes away.

`e` in ['a', 'b', 'c']  # evaluates as False
`b` in ['a', 'b', 'c']  # evaluates as True

EDIT: With the clarification, new answer:

Note that PHP arrays are vastly different from Python's, combining arrays and dicts into one confused structure. Python arrays always have indices from 0 to len(arr) - 1, so you can check whether your index is in that range. try/catch is a good way to do it pythonically, though.

If you're asking about the hash functionality of PHP "arrays" (Python's dict), then my previous answer still kind of stands:

`baz` in {'foo': 17, 'bar': 19}  # evaluates as False
`foo` in {'foo': 17, 'bar': 19}  # evaluates as True

For those using ui-router, my answer is somewhat similar to Ender2050's, but I prefer doing this via state name testing:

$scope.isActive = function (stateName) {
  var active = (stateName === $state.current.name);
  return active;
};

corresponding HTML:

<ul class="nav nav-sidebar">
    <li ng-class="{ active: isActive('app.home') }"><a ui-sref="app.home">Dashboard</a></li>
    <li ng-class="{ active: isActive('app.tiles') }"><a ui-sref="app.tiles">Tiles</a></li>
</ul>

Meanwhile there is another way of how to do it with f-strings:

cursor.execute(f"INSERT INTO table VALUES {var1}, {var2}, {var3},")

.ui-slider .ui-slider-handle{
    width:50px; 
    height:50px; 
    background:url(../images/slider_grabber.png) no-repeat; overflow: hidden; 
    position:absolute;
    top: -10px;
    border-style:none; 
}

In C# 7 we can use tuples to accomplish this:

public List<(int SomeVariable, string AnotherVariable)> TheMethod(SomeParameter)
{
  using (MyDC TheDC = new MyDC())
  {
     var TheQueryFromDB = (....
                       select new { SomeVariable = ....,
                                    AnotherVariable = ....}
                       ).ToList();

      return TheQueryFromDB
                .Select(s => (
                     SomeVariable = s.SomeVariable, 
                     AnotherVariable = s.AnotherVariable))
                 .ToList();
  }
}

You might need to install System.ValueTuple nuget package though.

from PIL import Image

image = Image.open('File.jpg')
image.show()

$mylabel.text( $mylabel.text().replace('-', '') );

Since text() gets the value, and text( "someValue" ) sets the value, you just place one inside the other.

Would be the equivalent of doing:

var newValue = $mylabel.text().replace('-', '');
$mylabel.text( newValue );

EDIT:

I hope I understood the question correctly. I'm assuming $mylabel is referencing a DOM element in a jQuery object, and the string is in the content of the element.

If the string is in some other variable not part of the DOM, then you would likely want to call the .replace() function against that variable before you insert it into the DOM.

Like this:

var someVariable = "-123456";
$mylabel.text( someVariable.replace('-', '') );

or a more verbose version:

var someVariable = "-123456";
someVariable = someVariable.replace('-', '');
$mylabel.text( someVariable );

there are 6 ways to do this in React,

number 1 and 2 and 3 are the best:

1-config CORS in the Server-Side

2-set headers manually like this:

resonse_object.header("Access-Control-Allow-Origin", "*");
resonse_object.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");

3-config NGINX for proxy_pass which is explained here.

4-bypass the Cross-Origin-Policy with chrom extension(only for development and not recommended !)

5-bypass the cross-origin-policy with URL bellow(only for development)

"https://cors-anywhere.herokuapp.com/{type_your_url_here}"

6-use proxy in your package.json file:(only for development)

if this is your API: http://45.456.200.5:7000/api/profile/

add this part in your package.json file: "proxy": "http://45.456.200.5:7000/",

and then make your request with the next parts of the api:

React.useEffect(() => {
    axios
        .get('api/profile/')
        .then(function (response) {
            console.log(response);
        })
        .catch(function (error) {
            console.log(error);
        });
});

            forms[i].addEventListener('change', testFunction,true);
        }
    }
}

I think I just discovered a way to apply overlapping conditions in the expected way using VBA. After hours of trying out different approaches I found that what worked was changing the "Applies to" range for the conditional format rule, after every single one was created!

use numpy

And then use the Histogram library function

If you don't have the Runnable references, on the first callback, get the obj of the message, and use removeCallbacksAndMessages() to remove all related callbacks.

Why not use the get function?

var a = [1,2,3,4];
var last = $(a).get(-1);

http://api.jquery.com/get/ More info

Edit: As pointed out by DelightedD0D, this isn't the correct function to use as per jQuery's docs but it does still provide the correct results. I recommend using Salty's answer to keep your code correct.

When you use android:background, you are replacing much of the styling and look and feel of a button with a blank color.

Update: As of the version 23.0.0 release of AppCompat, there is a new Widget.AppCompat.Button.Colored style which uses your theme's colorButtonNormal for the disabled color and colorAccent for the enabled color.

This allows you apply it to your button directly via

<Button
  ...
  style="@style/Widget.AppCompat.Button.Colored" />

If you need a custom colorButtonNormal or colorAccent, you can use a ThemeOverlay as explained in this pro-tip and android:theme on the button.

Previous Answer

You can use a drawable in your v21 directory for your background such as:

<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
        android:color="?attr/colorControlHighlight">
    <item android:drawable="?attr/colorPrimary"/>
</ripple>

This will ensure your background color is ?attr/colorPrimary and has the default ripple animation using the default ?attr/colorControlHighlight (which you can also set in your theme if you'd like).

Note: you'll have to create a custom selector for less than v21:

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

Assuming you have some colors you'd like for the default, pressed, and focused state. Personally, I took a screenshot of a ripple midway through being selected and pulled the primary/focused state out of that.

Two options I just ran into:

• http://sojo.sourceforge.net/
• http://supercsv.sourceforge.net/

The wp_trim_words function can limit the characters too by changing the $num_words variable. For anyone who might find useful.

<?php 
$id=58; 
$post = get_post($id); 
$content = apply_filters('the_content', $post->post_content); 

$customExcerpt = wp_trim_words( $content, $num_words = 26, $more = '' );
echo $customExcerpt;  
?>

My 2 cents:

If you are concatenating a significant amount of strings, you should be using the StringBuilder instead. IMO it's cleaner, and significantly faster.

I faced Same Problem When i am using Scrollview inside View Flipper or Dialog that case scrollViewObject.fullScroll(ScrollView.FOCUS_UP) returns false so that case scrollViewObject.smoothScrollTo(0, 0) is Worked for me

Scroll Focus Top

A very simple approach for me is just to create 2 classes.

public class ClassB
{
    public string id{ get; set; }
    public string name{ get; set; }
    public int status { get; set; }
    public DateTime? updated_at { get; set; }
}

public class ClassAList
{
    public IList<ClassB> root_name{ get; set; } 
}

And when you going to do serialization:

var classAList = new ClassAList();
//...
//assign some value
//...
var jsonString = JsonConvert.SerializeObject(classAList)

Lastly, you will see your desired result as the following:

{
  "root_name": [
    {
      "id": "1001",
      "name": "1000001",
      "status": 1010,
      "updated_at": "2016-09-28 16:10:48"
    },
    {
      "id": "1002",
      "name": "1000002",
      "status": 1050,
      "updated_at": "2016-09-28 16:55:55"
    }
  ]
}

Hope this helps!

Use Arrays.copyOf my friend.

You are running Python 2 code on Python 3. In Python 3, the module has been renamed to http.client.

You could try to run the 2to3 tool on your code, and try to have it translated automatically. References to httplib will automatically be rewritten to use http.client instead.

The point is to set the token on the interceptors for each request

import axios from "axios";
    
const httpClient = axios.create({
    baseURL: "http://youradress",
    // baseURL: process.env.APP_API_BASE_URL,
});

httpClient.interceptors.request.use(function (config) {
    const token = localStorage.getItem('token');
    config.headers.Authorization =  token ? `Bearer ${token}` : '';
    return config;
});

Firstly, in general:

If these .h files are indeed typical C-style header files (as opposed to being something completely different that just happens to be named with .h extension), then no, there's no reason to "compile" these header files independently. Header files are intended to be included into implementation files, not fed to the compiler as independent translation units.

Since a typical header file usually contains only declarations that can be safely repeated in each translation unit, it is perfectly expected that "compiling" a header file will have no harmful consequences. But at the same time it will not achieve anything useful.

Basically, compiling hello.h as a standalone translation unit equivalent to creating a degenerate dummy.c file consisting only of #include "hello.h" directive, and feeding that dummy.c file to the compiler. It will compile, but it will serve no meaningful purpose.

Secondly, specifically for GCC:

Many compilers will treat files differently depending on the file name extension. GCC has special treatment for files with .h extension when they are supplied to the compiler as command-line arguments. Instead of treating it as a regular translation unit, GCC creates a precompiled header file for that .h file.

You can read about it here: http://gcc.gnu.org/onlinedocs/gcc/Precompiled-Headers.html

So, this is the reason you might see .h files being fed directly to GCC.

There are mainly two possible ways to achieve this:

1. Serialize the data in some way:

   $postvalue = serialize($array); // Client side
   
   $array = unserialize($_POST['result']; // Server side
   

And then you can unserialize the posted values with unserialize($postvalue). Further information on this is here in the PHP manuals.

Alternativeley you can use the json_encode() and json_decode() functions to get a JSON formatted serialized string. You could even shrink the transmitted data with gzcompress() (note that this is performance intensive) and secure the transmitted data with base64_encode() (to make your data survive in non-8 bit clean transport layers) This could look like this:

    $postvalue = base64_encode(json_encode($array)); // Client side

    $array = json_decode(base64_decode($_POST['result'])); // Server side

A not recommended way to serialize your data (but very cheap in performance) is to simply use implode() on your array to get a string with all values separated by some specified character. On the server side you can retrieve the array with explode() then. But note that you shouldn't use a character for separation that occurs in the array values (or then escape it) and that you cannot transmit the array keys with this method.

2. Use the properties of special named input elements:

   $postvalue = "";
   foreach ($array as $v) {
     $postvalue .= '<input type="hidden" name="result[]" value="' .$v. '" />';
   }
   

   Like this you get your entire array in the $_POST['result'] variable if the form is sent. Note that this doesn't transmit array keys. However you can achieve this by using result[$key] as name of each field.

Everyone of these methods got their own advantages and disadvantages. What you use is mainly depending on how large your array will be, since you should try to send a minimal amount of data with all of this methods.

Another way to achieve the same is to store the array in a server side session instead of transmitting it client side. Like this you can access the array over the $_SESSION variable and don't have to transmit anything over the form. For this have a look at a basic usage example of sessions on php.net.

I ran into similar problem a while back and what was happening in my case was the outer recycler view was working perfectly fine but the the adapter of inner/second recycler view had minor issues all the methods like constructor got initiated and even getCount() method was being called, although the final methods responsible to generate view ie..

1. onBindViewHolder() methods never got called. --> Problem 1.

2. When it got called finally it never show the list items/rows of recycler view. --> Problem 2.

Reason why this happened :: When you put a recycler view inside another recycler view, then height of the first/outer recycler view is not auto adjusted. It is defined when the first/outer view is created and then it remains fixed. At that point your second/inner recycler view has not yet loaded its items and thus its height is set as zero and never changes even when it gets data. Then when onBindViewHolder() in your second/inner recycler view is called, it gets items but it doesn't have the space to show them because its height is still zero. So the items in the second recycler view are never shown even when the onBindViewHolder() has added them to it.

Solution :: you have to create your custom LinearLayoutManager for the second recycler view and that is it. To create your own LinearLayoutManager: Create a Java class with the name CustomLinearLayoutManager and paste the code below into it. NO CHANGES REQUIRED

public class CustomLinearLayoutManager extends LinearLayoutManager {

    private static final String TAG = CustomLinearLayoutManager.class.getSimpleName();

    public CustomLinearLayoutManager(Context context) {
        super(context);

    }

    public CustomLinearLayoutManager(Context context, int orientation, boolean reverseLayout) {
        super(context, orientation, reverseLayout);
    }

            if (getOrientation() == HORIZONTAL) {

                measuredDimension[1] = view.getMeasuredHeight() + p.bottomMargin + p.topMargin;
                recycler.recycleView(view);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

One line solution:

$option1ChkBox = array_key_exists('chkBoxName', $_POST) ? true : false;

You can use deparse and substitute to get the name of a function argument:

myfunc <- function(v1) {
  deparse(substitute(v1))
}

myfunc(foo)
[1] "foo"

You can check the return value from scanf. This code will just sit there until it receives a string.

int a;

do {
  // other code
  a = scanf("%s", url);

} while (a <= 0);

this is best solution ever

with underscore i had to use String() in the iteratee function

function isUniq(item) {
    return String(item.user);
}
var myUniqArray = _.uniq(myArray, isUniq);

It is stretching because align-self default value is stretch. there is two solution for this case : 1. set img align-self : center OR 2. set parent align-items : center

img {

   align-self: center
}

OR

.parent {
  align-items: center
}

I'm writing an updated answer for Python 3 to this question.

How is __eq__ handled in Python and in what order?

a == b

It is generally understood, but not always the case, that a == b invokes a.__eq__(b), or type(a).__eq__(a, b).

Explicitly, the order of evaluation is:

1. if b's type is a strict subclass (not the same type) of a's type and has an __eq__, call it and return the value if the comparison is implemented,
2. else, if a has __eq__, call it and return it if the comparison is implemented,
3. else, see if we didn't call b's __eq__ and it has it, then call and return it if the comparison is implemented,
4. else, finally, do the comparison for identity, the same comparison as is.

We know if a comparison isn't implemented if the method returns NotImplemented.

(In Python 2, there was a __cmp__ method that was looked for, but it was deprecated and removed in Python 3.)

Let's test the first check's behavior for ourselves by letting B subclass A, which shows that the accepted answer is wrong on this count:

class A:
    value = 3
    def __eq__(self, other):
        print('A __eq__ called')
        return self.value == other.value

class B(A):
    value = 4
    def __eq__(self, other):
        print('B __eq__ called')
        return self.value == other.value

a, b = A(), B()
a == b

which only prints B __eq__ called before returning False.

How do we know this full algorithm?

The other answers here seem incomplete and out of date, so I'm going to update the information and show you how how you could look this up for yourself.

This is handled at the C level.

We need to look at two different bits of code here - the default __eq__ for objects of class object, and the code that looks up and calls the __eq__ method regardless of whether it uses the default __eq__ or a custom one.

Default __eq__

Looking __eq__ up in the relevant C api docs shows us that __eq__ is handled by tp_richcompare - which in the "object" type definition in cpython/Objects/typeobject.c is defined in object_richcompare for case Py_EQ:.

    case Py_EQ:
        /* Return NotImplemented instead of False, so if two
           objects are compared, both get a chance at the
           comparison.  See issue #1393. */
        res = (self == other) ? Py_True : Py_NotImplemented;
        Py_INCREF(res);
        break;

So here, if self == other we return True, else we return the NotImplemented object. This is the default behavior for any subclass of object that does not implement its own __eq__ method.

How __eq__ gets called

Then we find the C API docs, the PyObject_RichCompare function, which calls do_richcompare.

Then we see that the tp_richcompare function, created for the "object" C definition is called by do_richcompare, so let's look at that a little more closely.

The first check in this function is for the conditions the objects being compared:

• are not the same type, but
• the second's type is a subclass of the first's type, and
• the second's type has an __eq__ method,

then call the other's method with the arguments swapped, returning the value if implemented. If that method isn't implemented, we continue...

    if (!Py_IS_TYPE(v, Py_TYPE(w)) &&
        PyType_IsSubtype(Py_TYPE(w), Py_TYPE(v)) &&
        (f = Py_TYPE(w)->tp_richcompare) != NULL) {
        checked_reverse_op = 1;
        res = (*f)(w, v, _Py_SwappedOp[op]);
        if (res != Py_NotImplemented)
            return res;
        Py_DECREF(res);

Next we see if we can lookup the __eq__ method from the first type and call it. As long as the result is not NotImplemented, that is, it is implemented, we return it.

    if ((f = Py_TYPE(v)->tp_richcompare) != NULL) {
        res = (*f)(v, w, op);
        if (res != Py_NotImplemented)
            return res;
        Py_DECREF(res);

Else if we didn't try the other type's method and it's there, we then try it, and if the comparison is implemented, we return it.

    if (!checked_reverse_op && (f = Py_TYPE(w)->tp_richcompare) != NULL) {
        res = (*f)(w, v, _Py_SwappedOp[op]);
        if (res != Py_NotImplemented)
            return res;
        Py_DECREF(res);
    }

Finally, we get a fallback in case it isn't implemented for either one's type.

The fallback checks for the identity of the object, that is, whether it is the same object at the same place in memory - this is the same check as for self is other:

    /* If neither object implements it, provide a sensible default
       for == and !=, but raise an exception for ordering. */
    switch (op) {
    case Py_EQ:
        res = (v == w) ? Py_True : Py_False;
        break;

Conclusion

In a comparison, we respect the subclass implementation of comparison first.

Then we attempt the comparison with the first object's implementation, then with the second's if it wasn't called.

Finally we use a test for identity for comparison for equality.

Here's a solution that doesn't use JS at all. It uses checkboxes instead.

You can hide the checkbox by adding this to your CSS:

.container input{
    display: none;
}

And then add some styling to make it look like a button.

Here's the source code that I modded.

Peer authentication means that postgres asks the operating system for your login name and uses this for authentication. To login as user "dev" using peer authentication on postgres, you must also be the user "dev" on the operating system.

You can find details to the authentication methods in the Postgresql documentation.

Hint: If no authentication method works anymore, disconnect the server from the network and use method "trust" for "localhost" (and double check that your server is not reachable through the network while method "trust" is enabled).

If you happen to be using numpy already (very popular for scientific and financial applications) you can save yourself an import.

import numpy as np    
np.random.shuffle(b)
print(b)

The posted answers are very good when working with data.frames. However, these tasks can be pretty inefficient from a memory perspective. With large data, removing a column can take an unusually long amount of time and/or fail due to out of memory errors. Package data.table helps address this problem with the := operator:

library(data.table)
> dt <- data.table(a = 1, b = 1, c = 1)
> dt[,a:=NULL]
     b c
[1,] 1 1

I should put together a bigger example to show the differences. I'll update this answer at some point with that.

The executable packer maven plugin can be used for exactly that purpose: creating standalone java applications containing all dependencies as JAR files in a specific folder.

Just add the following to your pom.xml inside the <build><plugins> section (be sure to replace the value of mainClass accordingly):

<plugin>
    <groupId>de.ntcomputer</groupId>
    <artifactId>executable-packer-maven-plugin</artifactId>
    <version>1.0.1</version>
    <configuration>
        <mainClass>com.example.MyMainClass</mainClass>
    </configuration>
    <executions>
        <execution>
            <goals>
                <goal>pack-executable-jar</goal>
            </goals>
        </execution>
    </executions>
</plugin>

The built JAR file is located at target/<YourProjectAndVersion>-pkg.jar after you run mvn package. All of its compile-time and runtime dependencies will be included in the lib/ folder inside the JAR file.

Disclaimer: I am the author of the plugin.

just simple:

.navbar{
    width:65% !important;
    margin:0px auto;
    left:0;
    right:0;
    padding:0;
}

or,

.navbar.navbar-fixed-top{
    width:65% !important;
    margin:0px auto;
    left:0;
    right:0;
    padding:0;
}

Hope it works (at least, for future searchers)

Try this:

I was using old version 1.0.beta.6 of handlebars, i think somewhere during 1.1 - 1.3 this functionality was added, so updating to 1.3.0 solved the issue, here is the usage:

Usage:

{{#each object}}
  Key {{@key}} : Value {{this}}
{{/people}}

Another way that could be used in some situations is to set the link color in the properties of the view that is taking the Spannable.

If your Spannable is going to be used in a TextView, for example, you can set the link color in the XML like this:

<TextView
    android:id="@+id/myTextView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:textColorLink="@color/your_color"
</TextView>

You can also set it in the code with:

TextView tv = (TextView) findViewById(R.id.myTextView);
tv.setLinkTextColor(your_color);

NPM in 2019

npm build no longer exists. You must call npm run build now. More info below.

TLDR;

npm install: installs dependencies, then calls the install from the package.json scripts field.

npm run build: runs the build field from the package.json scripts field.

NPM Scripts Field

https://docs.npmjs.com/misc/scripts

There are many things you can put into the npm package.json scripts field. Check out the documentation link above more above the lifecycle of the scripts - most have pre and post hooks that you can run scripts before/after install, publish, uninstall, test, start, stop, shrinkwrap, version.

To Complicate Things

• npm install is not the same as npm run install
• npm install installs package.json dependencies, then runs the package.json scripts.install
  • (Essentially calls npm run install after dependencies are installed.
• npm run install only runs the package.json scripts.install, it will not install dependencies.
• npm build used to be a valid command (used to be the same as npm run build) but it no longer is; it is now an internal command. If you run it you'll get: npm WARN build npm build called with no arguments. Did you mean to npm run-script build? You can read more on the documentation: https://docs.npmjs.com/cli/build

Extra Notes

There are still two top level commands that will run scripts, they are:

• npm start which is the same as npm run start
• npm test ==> npm run test

Another solution, this code was taken from android source code of Window You should just add these Two methods to your dialog source code.

@Override
public boolean onTouchEvent(MotionEvent event) {        
    if (isShowing() && (event.getAction() == MotionEvent.ACTION_DOWN
            && isOutOfBounds(getContext(), event) && getWindow().peekDecorView() != null)) {
        hide();
    }
    return false;
}

private boolean isOutOfBounds(Context context, MotionEvent event) {
    final int x = (int) event.getX();
    final int y = (int) event.getY();
    final int slop = ViewConfiguration.get(context).getScaledWindowTouchSlop();
    final View decorView = getWindow().getDecorView();
    return (x < -slop) || (y < -slop)
            || (x > (decorView.getWidth()+slop))
            || (y > (decorView.getHeight()+slop));
}

This solution doesnt have this problem :

This works great except that the activity underneath also reacts to the touch event. Is there some way to prevent this? – howettl

You could use ForEach, but you have to convert the IEnumerable<T> to a List<T> first.

list.Where(w => w.Name == "height").ToList().ForEach(s => s.Value = 30);

getCurrentActivity() is also in ReactContextBaseJavaModule.
(Since the this question was initially asked, many Android app also has ReactNative component - hybrid app.)

class ReactContext in ReactNative has the whole set of logic to maintain mCurrentActivity which is returned in getCurrentActivity().

Note: I wish getCurrentActivity() is implemented in Android Application class.

surround.vim is going to be your easiest answer. If you are truly set against using it, here are some examples for what you can do. Not necessarily the most efficient, but that's why surround.vim was written.

• Quote a word, using single quotes
  ciw'Ctrl+r"'
  • ciw - Delete the word the cursor is on, and end up in insert mode.
  • ' - add the first quote.
  • Ctrl+r" - Insert the contents of the " register, aka the last yank/delete.
  • ' - add the closing quote.
    
    
• Unquote a word that's enclosed in single quotes
  di'hPl2x
  • di' - Delete the word enclosed by single quotes.
  • hP - Move the cursor left one place (on top of the opening quote) and put the just deleted text before the quote.
  • l - Move the cursor right one place (on top of the opening quote).
  • 2x - Delete the two quotes.
    
    
• Change single quotes to double quotes
  va':s/\%V'\%V/"/g
  • va' - Visually select the quoted word and the quotes.
  • :s/ - Start a replacement.
  • \%V'\%V - Only match single quotes that are within the visually selected region.
  • /"/g - Replace them all with double quotes.

you have to do like this in your project level gradle file

allprojects {
    repositories {
        jcenter()
        maven { url "http://dl.appnext.com/" }
        maven { url "https://maven.google.com" }
    }
}

actually you have one vimrc in

/etc/vimrc

when you edit something in there the changes will effect all users
if you don't want that you can create a local vimrc in

~/.vimrc

the changes here will only effect the one user

For a jar file, the difference is in the classpath listed in the MANIFEST.MF file included in the jar if addClassPath is set to true in the maven-jar-plugin configuration. 'compile' dependencies will appear in the manifest, 'provided' dependencies won't.

One of my pet peeves is that these two words should have the same tense. Either compiled and provided, or compile and provide.

Use this code:

QFile inputFile(fileName);
if (inputFile.open(QIODevice::ReadOnly))
{
   QTextStream in(&inputFile);
   while (!in.atEnd())
   {
      QString line = in.readLine();
      ...
   }
   inputFile.close();
}

A hard reset will also resolve the problem

git reset --hard origin/master

#include <math.h>


printf ("%d", (int) pow (3, 4));

this error appeared to me because my php-fpm image enabled cron, and I have no idea why

If you download the jquery easing plugin (check it out),then you just have to add this to your main.js file:

$('a.smooth-scroll').on('click', function(event) {
    var $anchor = $(this);
    $('html, body').stop().animate({
        scrollTop: $($anchor.attr('href')).offset().top + 20
    }, 1500, 'easeInOutExpo');
    event.preventDefault();
});

and also dont forget to add the smooth-scroll class to your a tags like this:

 <li><a href="#about" class="smooth-scroll">About Us</a></li>

I have had this problem several times and it can be usually resolved with a clean and rebuild as answered by many before me. But this time this would not fix it.

I use my cordova app to build 2 seperate apps that share majority of the same codebase and it drives off the config.xml. I could not build in end up because i had a space in my id.

com.company AppName

instead of:

com.company.AppName

If anyone is in there config as regular as me. This could be your problem, I also have 3 versions of each app. Live / Demo / Test - These all have different ids.

com.company.AppName.Test

Easy mistake to make, but even easier to overlook. Spent loads of time rebuilding, checking plugins, versioning etc. Where I should have checked my config. First Stop Next Time!

// create table
var dt = new System.Data.DataTable("tableName");

// create fields
dt.Columns.Add("field1", typeof(int));
dt.Columns.Add("field2", typeof(string));

// insert row values
dt.Rows.Add(new Object[]{
                123456,
                "test",
                DateTime.Now
           });

If you use relative links to images then the images won't display as all folder structures are not preserved after the iOS app is compiled. What you can do is convert your local web folder into a bundle instead by adding the '.bundle' filename extension.

So if you local website is contained in a folder "www", this should be renamed to "www.bundle". This allows the image folders and directory structure to be preserved. Then load the 'index.html' file into the WebView as an HTML string with 'baseURL' (set to www.bundle path) to enable loading relative image links.

NSString *mainBundlePath = [[NSBundle mainBundle] resourcePath];
NSString *wwwBundlePath = [mainBundlePath stringByAppendingPathComponent:@"www.bundle"];
NSBundle *wwwBundle = [NSBundle bundleWithPath:wwwBundlePath];
if (wwwBundle != nil) {
    NSURL *baseURL = [NSURL fileURLWithPath:[wwwBundle bundlePath]];
    NSError *error = nil;
    NSString *page = [[NSBundle mainBundle] pathForResource:@"index.html" ofType:nil];
    NSString *pageSource = [NSString stringWithContentsOfFile:page encoding:NSUTF8StringEncoding error:&error];
    [self.webView loadHTMLString:pageSource baseURL:baseURL];
}

This is my Save Attachments script. You select all the messages that you want the attachments saved from, and it will save a copy there. It also adds text to the message body indicating where the attachment is saved. You could easily change the folder name to include the date, but you would need to make sure the folder existed before starting to save files.

' Check each selected item for attachments. If attachments exist,
' save them to the strFolderPath folder and strip them from the item.
For Each objMsg In objSelection

    ' This code only strips attachments from mail items.
    ' If objMsg.class=olMail Then
    ' Get the Attachments collection of the item.
    Set objAttachments = objMsg.Attachments
    lngCount = objAttachments.Count
    strDeletedFiles = ""

    If lngCount > 0 Then

        ' We need to use a count down loop for removing items

Your current combination of a POST with an HTTP 204 response is fine.

Using a POST as a universal replacement for a GET is not supported by the RFC, as each has its own specific purpose and semantics.

The purpose of a GET is to retrieve a resource. Therefore, while allowed, an HTTP 204 wouldn't be the best choice since content IS expected in the response. An HTTP 404 Not Found or an HTTP 410 Gone would be better choices if the server was unable to provide the requested resource.

The RFC also specifically calls out an HTTP 204 as an appropriate response for PUT, POST and DELETE, but omits it for GET.

See the RFC for the semantics of GET.

There are other response codes that could also be returned, indicating no content, that would be more appropriate than an HTTP 204.

For example, for a conditional GET you could receive an HTTP 304 Not Modified response which would contain no body content.

I have a similar table styled like so:

<table style="width:100%; table-layout:fixed">
    <tr>
        <td style="width: 150px">Hello, World!</td>
        <td>
            <div>
                <pre style="margin:0; overflow:scroll">My preformatted content</pre>
            </div>
        </td>
    </tr>
</table>

If you can use static imports, and your moral code allows them

public class ObjectUtils {
    private final Object obj;
    private ObjectUtils(Object obj) {
        this.obj = obj;
    }

    public static ObjectUtils thisObj(Object obj){
        return new ObjectUtils(obj);
    }

    public boolean isNotA(Class<?> clazz){
        return !clazz.isInstance(obj);
    }
}

And then...

import static notinstanceof.ObjectUtils.*;

public class Main {

    public static void main(String[] args) {
        String a = "";
        if (thisObj(a).isNotA(String.class)) {
            System.out.println("It is not a String");
        }
        if (thisObj(a).isNotA(Integer.class)) {
            System.out.println("It is not an Integer");
        }
    }    
}

This is just a fluent interface exercise, I'd never use that in real life code!
Go for your classic way, it won't confuse anyone else reading your code!

Have a look at gsoap that includes two iOS examples in the download package under ios_plugin. The tool converts WSDL to code for SOAP and XML REST.

I believe the following should work with many well-behaved classed in Python:

def copy(obj):
    return type(obj)(obj)

(Of course, I am not talking here about "deep copies," which is a different story, and which may be not a very clear concept -- how deep is deep enough?)

According to my tests with Python 3, for immutable objects, like tuples or strings, it returns the same object (because there is no need to make a shallow copy of an immutable object), but for lists or dictionaries it creates an independent shallow copy.

Of course this method only works for classes whose constructors behave accordingly. Possible use cases: making a shallow copy of a standard Python container class.

In the Plist add the following properties.

Status bar is initially hidden = YES

Here's an implementation that returns fractional seconds (i.e. 1.321 seconds)

/**

 *

 */
class FnxStopwatch
{
    /** @var float */
    private $start,
            $stop;

    public function start()
    {
        $this->start = self::microtime_float();
    }
    public function stop()
    {
        $this->stop = self::microtime_float();
    }
    public function getIntervalSeconds() : float
    {
        // NOT STARTED
        if (empty($this->start))
            return 0;
        // NOT STOPPED
        if (empty($this->stop))
            return ($this->stop - self::microtime_float());

        return $interval = $this->stop - $this->start;
    }

    /**
     * FOR MORE INFO SEE http://us.php.net/microtime
     *
     * @return float
     */
    private static function microtime_float() : float
    {
        list($usec, $sec) = explode(" ", microtime());

        return ((float)$usec + (float)$sec);
    }
}

One option is:

Object.keys(myObject).length

Sadly it not works under older IE versions (under 9).

If you need that compatibility, use the painful version:

var key, count = 0;
for(key in myObject) {
  if(myObject.hasOwnProperty(key)) {
    count++;
  }
}

I understand that the answer is given but I wrote a simple example to make it easy to understand for beginners like me:

var x = { println("x"); 15 }
lazy val y = { println("y"); x + 1 }
println("-----")
x = 17
println("y is: " + y)

Output of above code is:

x
-----
y
y is: 18

As it can be seen, x is printed when it's initialized, but y is not printed when it's initialized in same way (I have taken x as var intentionally here - to explain when y gets initialized). Next when y is called, it's initialized as well as value of last 'x' is taken into consideration but not the old one.

Hope this helps.

You can put <project> in "Where:" box to search from the current Sublime project from the Find in Files menu.

This is more useful than searching from the root folder for when your project is including or excluding particular folders or file extensions.

you can't animate every property,

here's a reference to which are the animatable properties

visibility is animatable while display isn't...

in your case you could also animate opacity or height depending of the kind of effect you want to render_

        update: function (value) {

This solution works for me : Tools -> AVD Manager -> click drop down arrow -> select Cold Boot Now

I know this is an old question but I want to share an example that I think explains bounded wildcards pretty well. java.util.Collections offers this method:

public static <T> void sort(List<T> list, Comparator<? super T> c) {
    list.sort(c);
}

If we have a List of T, the List can, of course, contain instances of types that extend T. If the List contains Animals, the List can contain both Dogs and Cats (both Animals). Dogs have a property "woofVolume" and Cats have a property "meowVolume." While we might like to sort based upon these properties particular to subclasses of T, how can we expect this method to do that? A limitation of Comparator is that it can compare only two things of only one type (T). So, requiring simply a Comparator<T> would make this method usable. But, the creator of this method recognized that if something is a T, then it is also an instance of the superclasses of T. Therefore, he allows us to use a Comparator of T or any superclass of T, i.e. ? super T.

VBScript doesn't have Try/Catch. (VBScript language reference. If it had Try, it would be listed in the Statements section.)

On Error Resume Next is the only error handling in VBScript. Sorry. If you want try/catch, JScript is an option. It's supported everywhere that VBScript is and has the same capabilities.

Check the default superclass's constructor. It need be public or protected.

This should remove the first element, and then you can return the remaining:

var myarray = ["item 1", "item 2", "item 3", "item 4"];_x000D_
    _x000D_
myarray.shift();_x000D_
alert(myarray);

As others have suggested, you could also use slice(1);

var myarray = ["item 1", "item 2", "item 3", "item 4"];_x000D_
  _x000D_
alert(myarray.slice(1));

Try setting "Integrated Security=False" in the connection string.

<add name="YourContext" connectionString="Data Source=<IPAddressOfDBServer>;Initial Catalog=<DBName>;USER ID=<youruserid>;Password=<yourpassword>;Integrated Security=False;MultipleActiveResultSets=True" providerName="System.Data.SqlClient"/>

The solution is very simple just kill all the running nodes and restart your node server and rebuild your native application and it works.

For Linix:

killall -9 node

For Windows:

taskkill /im node.exe

For Android native App:

react-native run-android 

For IOS native App:

react-native run-ios

Then finally,

npm start

I'm surprised no one has suggested tracking last update time per row:

mysql> CREATE TABLE foo (
  id INT PRIMARY KEY
  x INT,
  updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP 
                     ON UPDATE CURRENT_TIMESTAMP,
  KEY (updated_at)
);

mysql> INSERT INTO foo VALUES (1, NOW() - INTERVAL 3 DAY), (2, NOW());

mysql> SELECT * FROM foo;
+----+------+---------------------+
| id | x    | updated_at          |
+----+------+---------------------+
|  1 | NULL | 2013-08-18 03:26:28 |
|  2 | NULL | 2013-08-21 03:26:28 |
+----+------+---------------------+

mysql> UPDATE foo SET x = 1234 WHERE id = 1;

This updates the timestamp even though we didn't mention it in the UPDATE.

mysql> SELECT * FROM foo;
+----+------+---------------------+
| id | x    | updated_at          |
+----+------+---------------------+
|  1 | 1235 | 2013-08-21 03:30:20 | <-- this row has been updated
|  2 | NULL | 2013-08-21 03:26:28 |
+----+------+---------------------+

Now you can query for the MAX():

mysql> SELECT MAX(updated_at) FROM foo;
+---------------------+
| MAX(updated_at)     |
+---------------------+
| 2013-08-21 03:30:20 |
+---------------------+

Admittedly, this requires more storage (4 bytes per row for TIMESTAMP).
But this works for InnoDB tables before 5.7.15 version of MySQL, which INFORMATION_SCHEMA.TABLES.UPDATE_TIME doesn't.

select * from 
  (SELECT MEMBSHIP_ID
   FROM user_payment WHERE user_id=1
   order by paym_date desc) 
where rownum=1;

Here you go:

>>> data = """a,b,c
d,e,f
g,h,i
j,k,l"""
>>> data.split()  # split automatically splits through \n and space
['a,b,c', 'd,e,f', 'g,h,i', 'j,k,l']
>>> 

Neither of them worked for me for some reason.

I figured it out that for some reason python doesn't read %s. So use (?) instead of %S in you SQL Code.

And finally this worked for me.

   cursor.execute ("update tablename set columnName = (?) where ID = (?) ",("test4","4"))
   connect.commit()

Constructor is a special method which in theory is the "only" non-static method called by any static method. else its not allowed.

this is my answer, just use while and for

def remove_all(data, value):
    i = j = 0
    while j < len(data):
        if data[j] == value:
            j += 1
            continue
        data[i] = data[j]
        i += 1
        j += 1
    for x in range(j - i):
        data.pop()

Based on this code (which you provided in response to Alex's answer):

Editable newTxt=(Editable)userName1.getText(); 
String newString = newTxt.toString();

It looks like you're trying to get the text out of a TextView or EditText. If that's the case then this should work:

String newString = userName1.getText().toString(); 

If you use make generators like cmake, JUCE, etc. try to set a correct VS version target (2013, 2015, 2017) and regenerate the solution again.

Anyone struggling to find where to set redirect urls in the new console: APIs & Auth -> Credentials -> OAuth 2.0 client IDs -> Click the link to find all your redirect urls

Using the DB2 commands (no SQL) there is the possibility of executing

db2 LIST TABLES FOR ALL

This shows all the tables in all the schemas in the database.

ref: show all tables in DB2 using the LIST command

Can add disable like below and can get data on submit. something like this .. DEMO
