JQuery:

$(function () {
      $('.SendEmail').click(function (event) {
        var email = '[email protected]';
        var subject = 'Test';
        var emailBody = 'Hi Sample,';
        var attach = 'path';
        document.location = "mailto:"+email+"?subject="+subject+"&body="+emailBody+
            "?attach="+attach;
      });
    });

HTML:

 <button class="SendEmail">Send Email</button>

To get body lines use escape()

body_line =  escape("\n");

so

href = "mailto:[email protected]?body=hello,"+body_line+"I like this.";

Yes:

Use this to experiment with mailto form elements and link encoding.

You can enter subject, body (i.e. content), etc. into the form, hit the button and see the mailto html link that you can paste into your page.

You can even specify elements that are rarely known and used: cc, bcc, from emails.

This seems to work fine:

<button onclick="location.href='mailto:[email protected]';">send mail</button>

I don't know if it helps, but using jQuery, to hide an email address, I did :

    $(function() {
        // planque l'adresse mail
        var mailSplitted 
            = ['mai', 'to:mye', 'mail@', 'addre', 'ss.fr'];

        var link = mailSplitted.join('');
        link = '<a href="' + link + '"</a>';
        $('mytag').wrap(link);
    });

I hope it helps.

I have implement following it working for iOS devices but failed on android devices

<a  href="mailto:?subject=Your mate might be interested...&body=<div style='padding: 0;'><div style='padding: 0;'><p>I found this on the site I think you might find it interesting.  <a href='@(Request.Url.ToString())' >Click here </a></p></div></div>">Share This</a>

Whilst it is NOT possible to use HTML to format your email body you can add line breaks as has been previously suggested.

If you are able to use javascript then "encodeURIComponent()" might be of use like below...

var formattedBody = "FirstLine \n Second Line \n Third Line";
var mailToLink = "mailto:[email protected]?body=" + encodeURIComponent(formattedBody);
window.location.href = mailToLink;

Use %0D%0A for a line break in your body

• How to enter line break into mailto body command (by Christian Petters; 01 Apr 2008)

Example (Demo):

<a href="mailto:[email protected]?subject=Suggestions&body=name:%0D%0Aemail:">test</a>?
                                                                  ^^^^^^

Curiously in gmail for android %0D%0A doesn't work and <br> works:

<a href="mailto:[email protected]?subject=This%20is%20Subject&body=First line<br>Second line">
   click here to mail me
</a>

If you call daemon() and then daemonize a process, by default the current working directory will change to /. So if your program is a daemon then you should be looking for a core in / directory and not in the directory of the binary.

why not just use plain javascript?

document.getElementById("selectID").options.length = 0;

For the allowed characters you can use

^[a-zA-Z0-9~@#$^*()_+=[\]{}|\\,.?: -]*$

to validate a complete string that should consist of only allowed characters. Note that - is at the end (because otherwise it'd be a range) and a few characters are escaped.

For the invalid characters you can use

[<>'"/;`%]

to check for them.

To combine both into a single regex you can use

^(?=[a-zA-Z0-9~@#$^*()_+=[\]{}|\\,.?: -]*$)(?!.*[<>'"/;`%])

but you'd need a regex engine that allows lookahead.

$("#myDiv").load(location.href+" #myDiv>*","");

Not a general answer, but may be useful for the specific case where you are happy with the default python 2 encoding, but want to specify utf-8 for python 3:

if sys.version_info.major > 2:
    do_open = lambda filename: open(filename, encoding='utf-8')
else:
    do_open = lambda filename: open(filename)

with do_open(filename) as file:
    pass

The major issue might be the oracle database itself may not have started. So, you need to manually go via

run command -> services.msc

check for OracleXEService surely, it may be disabled

right click go to properties-> set it to Automatic and press Ok. Then just right click again and start.

This will start your database making you to connect to it

Finally, In sqlplus command line,

connect as sysdba

enter username as admin

then press enter, you'll be connected

private async Task DoAsync()
{
    await Task.Run(async () =>

This was a pain, using netBeans IDE 7.2.

1. You need to remember that Netbeans cleans up the Build folder whenever you rebuild, so

2. Add a resource folder to the src folder:

   • (project)
     • src
       • project package folder (contains .java files)
       • resources (whatever name you want)
       • images (optional subfolders)

3. After the clean/build this structure is propogated into the Build folder:
   

   • (project)
     
     • build
       
       • classes
         
         • project package folder (contains generated .class files)
           
         • resources (your resources)
           
         • images (your optional subfolders)
           

To access the resources:

dlabel = new JLabel(new ImageIcon(getClass().getClassLoader().getResource("resources/images/logo.png")));

and:

if (common.readFile(getClass().getResourceAsStream("/resources/allwise.ini"), buf).equals("OK")) {

worked for me. Note that in one case there is a leading "/" and in the other there isn't. So the root of the path to the resources is the "classes" folder within the build folder.

Double click on the executable jar file in the dist folder. The path to the resources still works.

Open the httpd.conf file and search for

"rewrite"

, then remove

"#"

at the starting of the line,so the line looks like.

LoadModule rewrite_module modules/mod_rewrite.so

then restart the wamp.

CSS will skip over style declarations it doesn't understand. Mozilla-based browsers will not understand -webkit-prefixed declarations, and WebKit-based browsers will not understand -moz-prefixed declarations.

Because of this, we can simply declare width twice:

elem {
    width: 100%;
    width: -moz-available;          /* WebKit-based browsers will ignore this. */
    width: -webkit-fill-available;  /* Mozilla-based browsers will ignore this. */
    width: fill-available;
}

The width: 100% declared at the start will be used by browsers which ignore both the -moz and -webkit-prefixed declarations or do not support -moz-available or -webkit-fill-available.

C:\xampp\mysql\bin\mysql -u root -p testdatabase < C:\Users\Juan\Desktop\databasebackup.sql

That worked for me to import 400MB file into my database.

2 simple steps

1. Install Bootstrap ( am installing latest version)

npm install bootstrap@next

2. Import into your project, add below line in your styles.scss

@import '~bootstrap';

Please Note your order of imports might matter, if you have other libraries which uses bootstrap, please keep this import statement on top

The End. :)

NOTE: below are my versions

angular : 9

node : v10.16.0

npm : 6.9.1

Wanted to give my contribution, as my regex cover all cases from OP and correctly group all relevant data on the group method (you don't need to post process the string to get each part of the uuid, this regex already get it for you)

([\d\w]{8})-?([\d\w]{4})-?([\d\w]{4})-?([\d\w]{4})-?([\d\w]{12})|[{0x]*([\d\w]{8})[0x, ]{4}([\d\w]{4})[0x, ]{4}([\d\w]{4})[0x, {]{5}([\d\w]{2})[0x, ]{4}([\d\w]{2})[0x, ]{4}([\d\w]{2})[0x, ]{4}([\d\w]{2})[0x, ]{4}([\d\w]{2})[0x, ]{4}([\d\w]{2})[0x, ]{4}([\d\w]{2})[0x, ]{4}([\d\w]{2})

From the javascript I tried from several ways and I could not.

You need an server side solution, for example on c# I did create an controller that call to the http, en deserialize the object, and the result is that when I call from javascript, I'm doing an request from my https://domain to my htpps://domain. Please see my c# code:

[Authorize]
public class CurrencyServicesController : Controller
{
    HttpClient client;
    //GET: CurrencyServices/Consultar?url=valores?moedas=USD&alt=json
    public async Task<dynamic> Consultar(string url)
    {
        client = new HttpClient();
        client.BaseAddress = new Uri("http://api.promasters.net.br/cotacao/v1/");
        client.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));
        System.Net.Http.HttpResponseMessage response = client.GetAsync(url).Result;

        var FromURL = response.Content.ReadAsStringAsync().Result;

        return JsonConvert.DeserializeObject(FromURL);
    }

And let me show to you my client side (Javascript)

<script async>
$(document).ready(function (data) {

    var TheUrl = '@Url.Action("Consultar", "CurrencyServices")?url=valores';
    $.getJSON(TheUrl)
        .done(function (data) {
            $('#DolarQuotation').html(
                '$ ' + data.valores.USD.valor.toFixed(2) + ','
            );
            $('#EuroQuotation').html(
                '€ ' + data.valores.EUR.valor.toFixed(2) + ','
            );

            $('#ARGPesoQuotation').html(
                'Ar$ ' + data.valores.ARS.valor.toFixed(2) + ''
            );

        });       

});

I wish that this help you! Greetings

Best way to handle such error-"Use Annotation". spring.xml-<context:component-scan base-package=com.SpringCollection.SpringCollection"/>

add annotation in that class for which you want to use Bean ID(i am using class "First")-

@Component

public class First {

Changes In Main Class**-

ApplicationContext context = new AnnotationConfigApplicationContext(First.class); use this.

Open command prompt go inside the maven folder and execute mvn -version, it will show you maven vesrion al

A common idiom for clearing standard containers is swapping with an empty version of the container:

void clear( std::queue<int> &q )
{
   std::queue<int> empty;
   std::swap( q, empty );
}

It is also the only way of actually clearing the memory held inside some containers (std::vector)

I think its help you try it.

public class Program
{

    public static List<T> GetEnamList<T>()
    {
        var enums = Enum.GetValues(typeof(T)).Cast<T>().Select(v => v).ToList();
        return enums;
    }
    private void LoadEnumList()
    {
        List<DayofWeek> dayofweeks = GetEnamList<DayofWeek>();

        foreach (var item in dayofweeks)
        {
            dayofweeks.Add(item);
        }
    }
}

    public enum DayofWeek
    {
        Monday,
        Tuesday,
        Wensday,
        Thursday,
        Friday,
        Sturday,
        Sunday
    }

In the absence of jQuery, I would use something like this:

<script>
    var divsToHide = document.getElementsByClassName("classname"); //divsToHide is an array
    for(var i = 0; i < divsToHide.length; i++){
        divsToHide[i].style.visibility = "hidden"; // or
        divsToHide[i].style.display = "none"; // depending on what you're doing
    }
<script>

This is taken from this SO question: Hide div by class id, however seeing that you're asking for "old-school" JS solution, I believe that getElementsByClassName is only supported by modern browsers

The difference between relational and non-relational is exactly that. The relational database architecture provides with constraints objects such as primary keys, foreign keys, etc that allows one to tie two or more tables in a relation. This is good so that we normalize our tables which is to say split information about what the database represents into many different tables, once can keep the integrity of the data.

For example, say you have a series of table that houses information about an employee. You could not delete a record from a table without deleting all the records that pertain to such record from the other tables. In this way you implement data integrity. The non-relational database doesn't provide this constraints constructs that will allow you to implement data integrity.

Unless you don't implement this constraint in the front end application that is utilized to populate the databases' tables, you are implementing a mess that can be compared with the wild west.

1. select *from table_name where boolean_column is False or Null;

   Is interpreted as "( boolean_column is False ) or (null)".

   It returns only rows where boolean_column is False as the second condition is always false.

2. select *from table_name where boolean_column is Null or False;

   Same reason. Interpreted as "(boolean_column is Null) or (False)"

3. select *from table_name where boolean_column is Null or boolean_column = False;

   This one is valid and returns 2 rows: false and null.

I just created the table to confirm. You might have typoed somewhere.

I am not a jquery expert, but how about,

$('#listItem').children().first().text()

Solved, using the following command set:

git reset --hard
git pull --rebase
git rebase --skip
git pull

The trick is to rebase the changes... We had some trouble rebasing one trivial commit, and so we simply skipped it using git rebase --skip (after having copied the files).

If the ActiveDirectory module is present add

import-module activedirectory

before your code.

To check if exist try:

get-module -listavailable

ActiveDirectory module is default present in windows server 2008 R2, install it in this way:

Import-Module ServerManager
Add-WindowsFeature RSAT-AD-PowerShell

For have it to work you need at least one DC in the domain as windows 2008 R2 and have Active Directory Web Services (ADWS) installed on it.

For Windows Server 2008 read here how to install it

We can download a specified branch by using following magical command:

The URI to open a specific channel in Slack app is:

TL:DR version:

//Objective-C
[self.picker selectRow:2 inComponent:0 animated:YES];
//Swift
picker.selectRow(2, inComponent:0, animated:true)

Either you didn't set your picker to select the row (which you say you seem to have done but anyhow):

- (void)selectRow:(NSInteger)row inComponent:(NSInteger)component animated:(BOOL)animated

OR you didn't use the the following method to get the selected item from your picker

- (NSInteger)selectedRowInComponent:(NSInteger)component

This will get the selected row as Integer from your picker and do as you please with it. This should do the trick for yah. Good luck.

Anyhow read the ref: https://developer.apple.com/documentation/uikit/uipickerview

EDIT:

An example of manually setting and getting of a selected row in a UIPickerView:

the .h file:

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController <UIPickerViewDelegate, UIPickerViewDataSource>
{
    UIPickerView *picker;
    NSMutableArray *source;
}

@property (nonatomic,retain) UIPickerView *picker;
@property (nonatomic,retain) NSMutableArray *source;

-(void)pressed;

@end

the .m file:

#import "ViewController.h"

@interface ViewController ()

@end
@implementation ViewController

@synthesize picker;
@synthesize source;

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}

- (void)viewDidUnload
{
    [super viewDidUnload];
    // Release any retained subviews of the main view.
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return YES;
}

- (void) viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];

    self.view.backgroundColor = [UIColor yellowColor];

    self.source = [[NSMutableArray alloc] initWithObjects:@"EU", @"USA", @"ASIA", nil];

    UIButton *pressme = [[UIButton alloc] initWithFrame:CGRectMake(20, 20, 280, 80)];
    [pressme setTitle:@"Press me!!!" forState:UIControlStateNormal];
    pressme.backgroundColor = [UIColor lightGrayColor];
    [pressme addTarget:self action:@selector(pressed) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:pressme];

    self.picker = [[UIPickerView alloc] initWithFrame:CGRectMake(20, 110, 280, 300)];
    self.picker.delegate = self;
    self.picker.dataSource = self;
    [self.view addSubview:self.picker];

    //This is how you manually SET(!!) a selection!
    [self.picker selectRow:2 inComponent:0 animated:YES];
}

//logs the current selection of the picker manually
-(void)pressed
{
    //This is how you manually GET(!!) a selection
    int row = [self.picker selectedRowInComponent:0];

    NSLog(@"%@", [source objectAtIndex:row]);
}

- (NSInteger)numberOfComponentsInPickerView:
(UIPickerView *)pickerView
{
    return 1;
}

- (NSInteger)pickerView:(UIPickerView *)pickerView
numberOfRowsInComponent:(NSInteger)component
{
    return [source count];
}

- (NSString *)pickerView:(UIPickerView *)pickerView
             titleForRow:(NSInteger)row
            forComponent:(NSInteger)component
{
    return [source objectAtIndex:row];
}

#pragma mark -
#pragma mark PickerView Delegate
-(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row
      inComponent:(NSInteger)component
{
//    NSLog(@"%@", [source objectAtIndex:row]);
}

@end

EDIT for Swift solution (Source: Dan Beaulieu's answer)

Define an Outlet:

@IBOutlet weak var pickerView: UIPickerView!  // for example

Then in your viewWillAppear or your viewDidLoad, for example, you can use the following:

pickerView.selectRow(rowMin, inComponent: 0, animated: true)
pickerView.selectRow(rowSec, inComponent: 1, animated: true)

If you inspect the Swift 2.0 framework you'll see .selectRow defined as:

func selectRow(row: Int, inComponent component: Int, animated: Bool) 

option clicking .selectRow in Xcode displays the following:

Try the following expression: boolean(path-to-node)

I like hvgotcodes' idea. My suggestion is to add a generic incrementer that compares the number complete to the number needed and then runs the final callback. This could be built into the final callback.

var sync = {
 callbacksToComplete = 3,
 callbacksCompleted = 0,
 addCallbackInstance = function(){
  this.callbacksCompleted++;
  if(callbacksCompleted == callbacksToComplete) {
   doFinalCallBack();
  }
 }
};

[Edited to reflect name updates.]

Phew, finally diagnosed this. Somehow, the offending Swift file EditTaskPopoverController.swift was in two different build phases.

It was in Compile Sources properly, with all the other Swift files, but it was also, for some very strange reason, in the Copy Bundle Resources phase as well, along with all my XIB and image resources.

I have no idea how it got there, but removing it from the extra build phase resolved the issue.

Open the terminal and type :

export ANDROID_HOME=/Applications/ADT/sdk

Add this to the PATH environment variable

export PATH=$PATH:$ANDROID_HOME/platform-tools

If the terminal doesn't locate the added path(s) from the .bash_profile, please run this command

source ~/.bash_profile

Hope it works to you!

Try this:

np.concatenate((a, np.array([a[0]])))

http://docs.scipy.org/doc/numpy/reference/generated/numpy.concatenate.html

concatenate needs both elements to be numpy arrays; however, a[0] is not an array. That is why it does not work.

might want to try something as simple as below in the command line:

sed -n '$=' filename

or

wc -l filename

I finally solved this problem. I used Samsung Galaxy S with Froyo. The "port" below is the same port what you use for the emulator (10.0.2.2:port). What I did:

1. first connect your real device with the USB cable (make sure you can upload the app on your device)
2. get the IP address from the device you connect, which starts with 192.168.x.x:port
3. open the "Network and Sharing Center"
4. click on the "Local Area Connection" from the device and choose "Details"
5. copy the "IPv4 address" to your app and replace it like: http://192.168.x.x:port/test.php
6. upload your app (again) to your real device
7. go to properties and turn "USB tethering" on
8. run your application on the device

It should now work.

Use System.Diagnostics.Process.Start() method.

Check out this article on how to use it.

Process.Start("notepad", "readme.txt");

string winpath = Environment.GetEnvironmentVariable("windir");
string path = System.IO.Path.GetDirectoryName(
              System.Windows.Forms.Application.ExecutablePath);

Process.Start(winpath + @"\Microsoft.NET\Framework\v1.0.3705\Installutil.exe",
path + "\\MyService.exe");

From what the error message complains about, it sounds like you should rather try to fix the source code. The compiler complains about difference in declaration, similar to for instance

void foo(int i);
...
void foo(double d) {
    ...
}

and this is not valid C code, hence the compiler complains.

Maybe your problem is that there is no prototype available when the function is used the first time and the compiler implicitly creates one that will not be static. If so the solution is to add a prototype somewhere before it is first used.

Unlike RDDs Spark Dataset (including Dataset[Row] a.k.a DataFrame) cannot use custom partitioner as for now. You can typically address that by creating an artificial partitioning column but it won't give you the same flexibility.

Spark < 1.6.0:

One thing you can do is to pre-partition input data before you create a DataFrame

import org.apache.spark.sql.types._
import org.apache.spark.sql.Row
import org.apache.spark.HashPartitioner

val schema = StructType(Seq(
  StructField("x", StringType, false),
  StructField("y", LongType, false),
  StructField("z", DoubleType, false)
))

val rdd = sc.parallelize(Seq(
  Row("foo", 1L, 0.5), Row("bar", 0L, 0.0), Row("??", -1L, 2.0),
  Row("foo", -1L, 0.0), Row("??", 3L, 0.6), Row("bar", -3L, 0.99)
))

val partitioner = new HashPartitioner(5) 

val partitioned = rdd.map(r => (r.getString(0), r))
  .partitionBy(partitioner)
  .values

val df = sqlContext.createDataFrame(partitioned, schema)

Since DataFrame creation from an RDD requires only a simple map phase existing partition layout should be preserved*:

assert(df.rdd.partitions == partitioned.partitions)

The same way you can repartition existing DataFrame:

sqlContext.createDataFrame(
  df.rdd.map(r => (r.getInt(1), r)).partitionBy(partitioner).values,
  df.schema
)

So it looks like it is not impossible. The question remains if it make sense at all. I will argue that most of the time it doesn't:

1. Repartitioning is an expensive process. In a typical scenario most of the data has to be serialized, shuffled and deserialized. From the other hand number of operations which can benefit from a pre-partitioned data is relatively small and is further limited if internal API is not designed to leverage this property.

   • joins in some scenarios, but it would require an internal support,
   • window functions calls with matching partitioner. Same as above, limited to a single window definition. It is already partitioned internally though, so pre-partitioning may be redundant,
   • simple aggregations with GROUP BY - it is possible to reduce memory footprint of the temporary buffers**, but overall cost is much higher. More or less equivalent to groupByKey.mapValues(_.reduce) (current behavior) vs reduceByKey (pre-partitioning). Unlikely to be useful in practice.
   • data compression with SqlContext.cacheTable. Since it looks like it is using run length encoding, applying OrderedRDDFunctions.repartitionAndSortWithinPartitions could improve compression ratio.

2. Performance is highly dependent on a distribution of the keys. If it is skewed it will result in a suboptimal resource utilization. In the worst case scenario it will be impossible to finish the job at all.

3. A whole point of using a high level declarative API is to isolate yourself from a low level implementation details. As already mentioned by @dwysakowicz and @RomiKuntsman an optimization is a job of the Catalyst Optimizer. It is a pretty sophisticated beast and I really doubt you can easily improve on that without diving much deeper into its internals.

Partitioning with JDBC sources:

JDBC data sources support predicates argument. It can be used as follows:

sqlContext.read.jdbc(url, table, Array("foo = 1", "foo = 3"), props)

It creates a single JDBC partition per predicate. Keep in mind that if sets created using individual predicates are not disjoint you'll see duplicates in the resulting table.

partitionBy method in DataFrameWriter:

Spark DataFrameWriter provides partitionBy method which can be used to "partition" data on write. It separates data on write using provided set of columns

val df = Seq(
  ("foo", 1.0), ("bar", 2.0), ("foo", 1.5), ("bar", 2.6)
).toDF("k", "v")

df.write.partitionBy("k").json("/tmp/foo.json")

This enables predicate push down on read for queries based on key:

val df1 = sqlContext.read.schema(df.schema).json("/tmp/foo.json")
df1.where($"k" === "bar")

but it is not equivalent to DataFrame.repartition. In particular aggregations like:

val cnts = df1.groupBy($"k").sum()

will still require TungstenExchange:

cnts.explain

// == Physical Plan ==
// TungstenAggregate(key=[k#90], functions=[(sum(v#91),mode=Final,isDistinct=false)], output=[k#90,sum(v)#93])
// +- TungstenExchange hashpartitioning(k#90,200), None
//    +- TungstenAggregate(key=[k#90], functions=[(sum(v#91),mode=Partial,isDistinct=false)], output=[k#90,sum#99])
//       +- Scan JSONRelation[k#90,v#91] InputPaths: file:/tmp/foo.json

bucketBy method in DataFrameWriter (Spark >= 2.0):

bucketBy has similar applications as partitionBy but it is available only for tables (saveAsTable). Bucketing information can used to optimize joins:

// Temporarily disable broadcast joins
spark.conf.set("spark.sql.autoBroadcastJoinThreshold", -1)

df.write.bucketBy(42, "k").saveAsTable("df1")
val df2 = Seq(("A", -1.0), ("B", 2.0)).toDF("k", "v2")
df2.write.bucketBy(42, "k").saveAsTable("df2")

// == Physical Plan ==
// *Project [k#41, v#42, v2#47]
// +- *SortMergeJoin [k#41], [k#46], Inner
//    :- *Sort [k#41 ASC NULLS FIRST], false, 0
//    :  +- *Project [k#41, v#42]
//    :     +- *Filter isnotnull(k#41)
//    :        +- *FileScan parquet default.df1[k#41,v#42] Batched: true, Format: Parquet, Location: InMemoryFileIndex[file:/spark-warehouse/df1], PartitionFilters: [], PushedFilters: [IsNotNull(k)], ReadSchema: struct<k:string,v:int>
//    +- *Sort [k#46 ASC NULLS FIRST], false, 0
//       +- *Project [k#46, v2#47]
//          +- *Filter isnotnull(k#46)
//             +- *FileScan parquet default.df2[k#46,v2#47] Batched: true, Format: Parquet, Location: InMemoryFileIndex[file:/spark-warehouse/df2], PartitionFilters: [], PushedFilters: [IsNotNull(k)], ReadSchema: struct<k:string,v2:double>

* By partition layout I mean only a data distribution. partitioned RDD has no longer a partitioner. ** Assuming no early projection. If aggregation covers only small subset of columns there is probably no gain whatsoever.

My site is hosted on MochaHost, i had a tough time to setup the .htaccess file so that i can remove the index.php from my urls. However, after some googling, i combined the answer on this thread and other answers. My final working .htaccess file has the following contents:

<IfModule mod_rewrite.c>
    # Turn on URL rewriting
    RewriteEngine On

    # If your website begins from a folder e.g localhost/my_project then 
    # you have to change it to: RewriteBase /my_project/
    # If your site begins from the root e.g. example.local/ then
    # let it as it is
    RewriteBase /

    # Protect application and system files from being viewed when the index.php is missing
    RewriteCond $1 ^(application|system|private|logs)

    # Rewrite to index.php/access_denied/URL
    RewriteRule ^(.*)$ index.php/access_denied/$1 [PT,L]

    # Allow these directories and files to be displayed directly:
    RewriteCond $1 ^(index\.php|robots\.txt|favicon\.ico|public|app_upload|assets|css|js|images)

    # No rewriting
    RewriteRule ^(.*)$ - [PT,L]

    # Rewrite to index.php/URL
    RewriteRule ^(.*)$ index.php?/$1 [PT,L]
</IfModule>

BEGIN
  FOR r IN (select sid,serial# from v$session where username='user')
  LOOP
      EXECUTE IMMEDIATE 'alter system kill session ''' || r.sid  || ',' 
        || r.serial# || ''' immediate';
  END LOOP;
END;

This should work - I just changed your script to add the immediate keyword. As the previous answers pointed out, the kill session only marks the sessions for killing; it does not do so immediately but later when convenient.

From your question, it seemed you are expecting to see the result immediately. So immediate keyword is used to force this.

Pickle uses different protocols to convert your data to a binary stream.

• In python 2 there are 3 different protocols (0, 1, 2) and the default is 0.

• In python 3 there are 5 different protocols (0, 1, 2, 3, 4) and the default is 3.

You must specify in python 3 a protocol lower than 3 in order to be able to load the data in python 2. You can specify the protocol parameter when invoking pickle.dump.

You cannot return value after resolving promise. Instead call another function when promise is resolved:

function justTesting() {
    promise.then(function(output) {
        // instead of return call another function
        afterResolve(output + 1);
    });
}

function afterResolve(result) {
    // do something with result
}

var test = justTesting();

xcopy /y /d  "$(ProjectDir)External\*.dll" "$(TargetDir)"

You can also refer to a relative path, the next example will find the DLL in a folder located one level above the project folder. If you have multiple projects that use the DLL in a single solution, this places the source of the DLL in a common area reachable when you set any of them as the Startup Project.

xcopy /y /d  "$(ProjectDir)..\External\*.dll" "$(TargetDir)"

The /y option copies without confirmation. The /d option checks to see if a file exists in the target and if it does only copies if the source has a newer timestamp than the target.

I found that in at least newer versions of Visual Studio, such as VS2109, $(ProjDir) is undefined and had to use $(ProjectDir) instead.

Leaving out a target folder in xcopy should default to the output directory. That is important to understand reason $(OutDir) alone is not helpful.

$(OutDir), at least in recent versions of Visual Studio, is defined as a relative path to the output folder, such as bin/x86/Debug. Using it alone as the target will create a new set of folders starting from the project output folder. Ex: … bin/x86/Debug/bin/x86/Debug.

Combining it with the project folder should get you to the proper place. Ex: $(ProjectDir)$(OutDir).

However $(TargetDir) will provide the output directory in one step.

Frank Heikens answer will only update database ownership. Often, you also want to update ownership of contained objects (including tables). Starting with Postgres 8.2, REASSIGN OWNED is available to simplify this task.

IMPORTANT EDIT!

Never use REASSIGN OWNED when the original role is postgres, this could damage your entire DB instance. The command will update all objects with a new owner, including system resources (postgres0, postgres1, etc.)

First, connect to admin database and update DB ownership:

psql
postgres=# REASSIGN OWNED BY old_name TO new_name;

This is a global equivalent of ALTER DATABASE command provided in Frank's answer, but instead of updating a particular DB, it change ownership of all DBs owned by 'old_name'.

The next step is to update tables ownership for each database:

psql old_name_db
old_name_db=# REASSIGN OWNED BY old_name TO new_name;

This must be performed on each DB owned by 'old_name'. The command will update ownership of all tables in the DB.

I had a similar problem. Looked over the html several times and was sure it was correct. Then I started playing around with the order of jquery and bootstrap javascript.

Originally I had bootstrap.min.js loading BEFORE jquery.min.js. In this state, the menu would not expand when clicking on the menu icon.

Then I changed the order so that bootstrap.min.js came after jquery.min.js, and this solved the problem. I don't know enough about javascript to explain why this caused the problem (or fixed it), but that is what worked for me.

Additional info:

Both scripts are located at the bottom of the page, just before the tag. Both scripts are hosted on CDNs, not locally hosted.

If you're pretty sure your code is correct, give this a try.

• RenderPartial() is a void method that writes to the response stream. A void method, in C#, needs a ; and hence must be enclosed by { }.

• Partial() is a method that returns an MvcHtmlString. In Razor, You can call a property or a method that returns such a string with just a @ prefix to distinguish it from plain HTML you have on the page.

There are more suitable functions for this in os package. But if you have to use os.walk, here is what I come up with

def walkdir(dirname):
    for cur, _dirs, files in os.walk(dirname):
        pref = ''
        head, tail = os.path.split(cur)
        while head:
            pref += '---'
            head, _tail = os.path.split(head)
        print(pref+tail)
        for f in files:
            print(pref+'---'+f)

output:

>>> walkdir('.')

Clear your browser cache. Started getting this error in Chrome and then I created a new client id and was still getting the issue. Opened firefox and it worked, so I cleared the cache on Chrome and it started working.

Simple code to check pointer aliasing:

int main () {
    int a = 10, b = 20;
    int *p1, *p2, *p3, *p4;

    p1 = &a;
    p2 = &a;
    if(p1 == p2){
        std::cout<<"p1 and p2 alias each other"<<std::endl;
    }
    else{
        std::cout<<"p1 and p2 do not alias each other"<<std::endl;
    }
    //------------------------
    p3 = &a;
    p4 = &b;
    if(p3 == p4){
        std::cout<<"p3 and p4 alias each other"<<std::endl;
    }
    else{
        std::cout<<"p3 and p4 do not alias each other"<<std::endl;
    }
    return 0;
}

Output:

p1 and p2 alias each other
p3 and p4 do not alias each other

I don't think there is a general purpose tuple class in Java but a custom one might be as easy as the following:

public class Tuple<X, Y> { 
  public final X x; 
  public final Y y; 
  public Tuple(X x, Y y) { 
    this.x = x; 
    this.y = y; 
  } 
} 

Of course, there are some important implications of how to design this class further regarding equality, immutability, etc., especially if you plan to use instances as keys for hashing.

You probably did some history rewriting? Your local branch diverged from the one on the server. Run this command to get a better understanding of what happened:

gitk HEAD @{u}

I would strongly recommend you try to understand where this error is coming from. To fix it, simply run:

git push -f

The -f makes this a “forced push” and overwrites the branch on the server. That is very dangerous when you are working in team. But since you are on your own and sure that your local state is correct this should be fine. You risk losing commit history if that is not the case.

<meta charset="utf-8"> was introduced with/for HTML5.

As mentioned in the documentation, both are valid. However, <meta charset="utf-8"> is only for HTML5 (and easier to type/remember).

In due time, the old style is bound to become deprecated in the near future. I'd stick to the new <meta charset="utf-8">.

There's only one way, but up. In tech's case, that's phasing out the old (really, REALLY fast)

Documentation: HTML meta charset Attribute—W3Schools

If you also want to name the constraint, use this:

ALTER TABLE myTable
  ADD CONSTRAINT constraintName 
    UNIQUE (columnName);

To initialize long you need to append "L" to the end.
It can be either uppercase or lowercase.

All the numeric values are by default int. Even when you do any operation of byte with any integer, byte is first promoted to int and then any operations are performed.

Try this

byte a = 1; // declare a byte
a = a*2; //  you will get error here

You get error because 2 is by default int.
Hence you are trying to multiply byte with int. Hence result gets typecasted to int which can't be assigned back to byte.

In addition to the accepted answer, there's a third option that can be useful in some cases:

v1 with random MAC ("v1mc")

You can make a hybrid between v1 & v4 by deliberately generating v1 UUIDs with a random broadcast MAC address (this is allowed by the v1 spec). The resulting v1 UUID is time dependant (like regular v1), but lacks all host-specific information (like v4). It's also much closer to v4 in it's collision-resistance: v1mc = 60 bits of time + 61 random bits = 121 unique bits; v4 = 122 random bits.

First place I encountered this was Postgres' uuid_generate_v1mc() function. I've since used the following python equivalent:

from os import urandom
from uuid import uuid1
_int_from_bytes = int.from_bytes  # py3 only

def uuid1mc():
    # NOTE: The constant here is required by the UUIDv1 spec...
    return uuid1(_int_from_bytes(urandom(6), "big") | 0x010000000000)

(note: I've got a longer + faster version that creates the UUID object directly; can post if anyone wants)

In case of LARGE volumes of calls/second, this has the potential to exhaust system randomness. You could use the stdlib random module instead (it will probably also be faster). But BE WARNED: it only takes a few hundred UUIDs before an attacker can determine the RNG state, and thus partially predict future UUIDs.

import random
from uuid import uuid1

def uuid1mc_insecure():
    return uuid1(random.getrandbits(48) | 0x010000000000)

Paging Logic

public Pagination GetCategoryPaging(int currentPage, int recordCount, string query)
{
    string pageClass = string.Empty; int pageSize = 10, innerCount = 5;

    Pagination pagination = new Pagination();
    pagination.Pages = new List<PageEntity>();
    pagination.Next = currentPage + 1;
    pagination.Previous = ((currentPage - 1) > 0) ? (currentPage - 1) : 1;

    int totalPages = ((int)recordCount % pageSize) == 0 ? (int)recordCount / pageSize : (int)recordCount / pageSize + 1;

    int loopStart = 1, loopCount = 1;

    if ((currentPage - 2) > 0)
    {
        loopStart = (currentPage - 2);
    }

    for (int i = loopStart; i <= totalPages; i++)
    {
        pagination.Pages.Add(new PageEntity { Page = i, Class = string.Empty });

        if (loopCount == innerCount)
        { break; }

        loopCount++;
    }

    if (totalPages <= innerCount)

    foreach (var item in pagination.Pages.Where(x => x.Page == currentPage))
    {

    }
    /* to be Fetched from database using count */
    int recordCount = 100;

    Place place = new Place();
    Pagination pagination = place.GetCategoryPaging(currentPage, recordCount, search);

    return PartialView("Controls/_Pagination", pagination);

Lawrence has given you a good answer. But if you want more control over what gets exported to where in Excel see Modules: Sample Excel Automation - cell by cell which is slow and Modules: Transferring Records to Excel with Automation You can do things such as export the recordset starting in row 2 and insert custom text in row 1. As well as any custom formatting required.

if (diff.Days > 30)

With WinForms you can use the ErrorProvider in conjunction with the Validating event to handle the validation of user input. The Validating event provides the hook to perform the validation and ErrorProvider gives a nice consistent approach to providing the user with feedback on any error conditions.

While I cannot reproduce your error (as none of your team mates can either), I have a suggestion, that might help you.

Have you heard of the Byte Order Mark? As it appears on line 1 it is a likely candidate for your troubles. Maybe you changed a setting somewhere that somehow leads to the error. This quote from the Wikipedia article is particularly relevant I think:

BOM use is optional. Its presence interferes with the use of UTF-8 by software that does not expect non-ASCII bytes at the start of a file but that could otherwise handle the text stream.

To answer your titular question, you use [0] to access the first element, but as it stands mandrill_events contains a string not an array, so mandrill_events[0] will just get you the first character, '['.

So either correct your source to:

var req = { mandrill_events: [{"event":"inbound","ts":1426249238}] };

and then req.mandrill_events[0], or if you're stuck with it being a string, parse the JSON the string contains:

var req = { mandrill_events: '[{"event":"inbound","ts":1426249238}]' };
var mandrill_events = JSON.parse(req.mandrill_events);
var result = mandrill_events[0];

You can do that by storing cookies on client side.

now starting 2015 all (major?) browsers seem to alow c.width and c.height to get the canvas internal size, but:

the question as the answers are missleading, because the a canvas has in principle 2 different/independent sizes.

The "html" lets say CSS width/height and its own (attribute-) width/height

look at this short example of different sizing, where I put a 200/200 canvas into a 300/100 html-element

With most examples (all I saw) there is no css-size set, so theese get implizit the width and height of the (drawing-) canvas size. But that is not a must, and can produce funy results, if you take the wrong size - ie. css widht/height for inner positioning.

The preferred way is to use a JavaScript library such as jQuery and set your data option as an object, then let jQuery do the encoding, like this:

$.ajax({
  type: "POST",
  url: "/link.json",
  data: { value: poststr },
  error: function(){ alert('some error occured'); }
});

If you can't use jQuery (which is pretty much the standard these days), use encodeURIComponent.

Although there is an accepted answer I don't feel that it is the right one. It is the simplest way to achieve what is needed, but even if already enabled in InnoDB (actually docs tell you that you still should get NULL ...), if you read MySQL docs, even in current version (8.0) using UPDATE_TIME is not the right option, because:

Timestamps are not persisted when the server is restarted or when the table is evicted from the InnoDB data dictionary cache.

If I understand correctly (can't verify it on a server right now), timestamp gets reset after server restart.

As for real (and, well, costly) solutions, you have Bill Karwin's solution with CURRENT_TIMESTAMP and I'd like to propose a different one, that is based on triggers (I'm using that one).

You start by creating a separate table (or maybe you have some other table that can be used for this purpose) which will work like a storage for global variables (here timestamps). You need to store two fields - table name (or whatever value you'd like to keep here as table id) and timestamp. After you have it, you should initialize it with this table id + starting date (NOW() is a good choice :) ).

Now, you move to tables you want to observe and add triggers AFTER INSERT/UPDATE/DELETE with this or similar procedure:

CREATE PROCEDURE `timestamp_update` ()
BEGIN
    UPDATE `SCHEMA_NAME`.`TIMESTAMPS_TABLE_NAME`
    SET `timestamp_column`=DATE_FORMAT(NOW(), '%Y-%m-%d %T')
    WHERE `table_name_column`='TABLE_NAME';
END

Simply using ImageButton instead of Button fixes the problem.

<ImageButton android:layout_width="30dp"
             android:layout_height="30dp"
             android:src="@drawable/bgimage" />

and you can set

android:background="@null"

to remove button background if you want.

Quick Fix !! :-)

When you specify position:absolute it positions itself to the next-highest element with position:relative. In this case, that's the .project div.

If you give the image's immediate parent div a style of position:relative, the overlay will key to that instead of the div which includes the text. For example: http://jsfiddle.net/7gYUU/1/

 <div class="parent">
    <img src="http://placehold.it/500x500" class="img-responsive"/>
    <div class="fa fa-plus project-overlay"></div>
 </div>

.parent {
   position: relative;

Synchronous inspection

Assigning promises-for-later-needed-values to variables and then getting their value via synchronous inspection. The example uses bluebird's .value() method but many libraries provide similar method.

function getExample() {
    var a = promiseA(…);

    return a.then(function() {
        // some processing
        return promiseB(…);
    }).then(function(resultB) {
        // a is guaranteed to be fulfilled here so we can just retrieve its
        // value synchronously
        var aValue = a.value();
    });
}

This can be used for as many values as you like:

function getExample() {
    var a = promiseA(…);

    var b = a.then(function() {
        return promiseB(…)
    });

    var c = b.then(function() {
        return promiseC(…);
    });

    var d = c.then(function() {
        return promiseD(…);
    });

    return d.then(function() {
        return a.value() + b.value() + c.value() + d.value();
    });
}

You can also use Apache's ExceptionUtils.

Example:

import org.apache.commons.lang.exception.ExceptionUtils;
import org.apache.log4j.Logger;


public class Test {

    static Logger logger = Logger.getLogger(Test.class);

    public static void main(String[] args) {

        try{
            String[] avengers = null;
            System.out.println("Size: "+avengers.length);
        } catch (NullPointerException e){
            logger.info(ExceptionUtils.getFullStackTrace(e));
        }
    }

}

Console output:

java.lang.NullPointerException
    at com.aimlessfist.avengers.ironman.Test.main(Test.java:11)

I found the solution.

dim bExists
ssig="Unable to open registry key"

set wshShell= Wscript.CreateObject("WScript.Shell")
strKey = "HKEY_USERS\.Default\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Digest\"
on error resume next
present = WshShell.RegRead(strKey)
if err.number<>0 then
    if right(strKey,1)="\" then    'strKey is a registry key
        if instr(1,err.description,ssig,1)<>0 then
            bExists=true
        else
            bExists=false
        end if
    else    'strKey is a registry valuename
        bExists=false
    end if
    err.clear
else
    bExists=true
end if
on error goto 0
if bExists=vbFalse then
    wscript.echo strKey & " does not exist."
else
    wscript.echo strKey & " exists."
end if

With jQuery 1.6 version you can use the .promise() method.

$(selector).fadeOut('slow');
$(selector).promise().done(function(){
    // will be called when all the animations on the queue finish
});

Just stumbled accross this post.

Some time ago I made a suggestion on Visual Studio Connect about adding a new ??? operator.

http://visualstudio.uservoice.com/forums/121579-visual-studio/suggestions/4104392-add-as-an-recursive-null-reference-check-opera

This would require some work from the framework team but don't need to alter the language but just do some compiler magic. The idea was that the compiler should change this code (syntax not allowed atm)

string product_name = Order.OrderDetails[0].Product.Name ??? "no product defined";

into this code

Func<string> _get_default = () => "no product defined"; 
string product_name = Order == null 
    ? _get_default.Invoke() 
    : Order.OrderDetails[0] == null 
        ? _get_default.Invoke() 
        : Order.OrderDetails[0].Product == null 
            ? _get_default.Invoke() 
            : Order.OrderDetails[0].Product.Name ?? _get_default.Invoke()

For null check this could look like

bool isNull = (Order.OrderDetails[0].Product ??? null) == null;

hmm.. just found the answer. it's easier then i thought. it just needs a bunch more stuff:

@echo off
if not exist log.txt GOTO :write
echo Date/Time last login:
type log.txt
del log.txt
:write
echo %date%, %time%. >> log.txt
@pause
exit

So it first reads the log.txt file and deletes it. After that it just get a new file (log.txt) with the date & time!

I hope this helps other people!

(the only prob is that the first time it does not work, but then just enter in random value at log.txt.) (This problem is solved and edited.)

You are using Python 2 methodology instead of Python 3.

Change:

outfile=open('./immates.csv','wb')

To:

outfile=open('./immates.csv','w')

and you will get a file with the following output:

SNo,States,Dist,Population
1,Andhra Pradesh,13,49378776
2,Arunachal Pradesh,16,1382611
3,Assam,27,31169272
4,Bihar,38,103804637
5,Chhattisgarh,19,25540196
6,Goa,2,1457723
7,Gujarat,26,60383628
.....

In Python 3 csv takes the input in text mode, whereas in Python 2 it took it in binary mode.

Edited to Add

Here is the code I ran:

url='http://www.mapsofindia.com/districts-india/'
html = urllib.request.urlopen(url).read()
soup = BeautifulSoup(html)
table=soup.find('table', attrs={'class':'tableizer-table'})
list_of_rows=[]
for row in table.findAll('tr')[1:]:
    list_of_cells=[]
    for cell in row.findAll('td'):
        list_of_cells.append(cell.text)
    list_of_rows.append(list_of_cells)
outfile = open('./immates.csv','w')
writer=csv.writer(outfile)
writer.writerow(['SNo', 'States', 'Dist', 'Population'])
writer.writerows(list_of_rows)

I think you can use display as grid:

.parent { display: grid };

It depends on the database to which you're trying to connect, the method by which you created the connection, and the version of Excel that you're using. (Also, most probably, the version of the relevant ODBC driver on your computer.)

The following examples are using SQL Server 2008 and Excel 2007, both on my local machine.

When I used the Data Connection Wizard (on the Data tab of the ribbon, in the Get External Data section, under From Other Sources), I saw the same thing that you did: the Parameters button was disabled, and adding a parameter to the query, something like select field from table where field2 = ?, caused Excel to complain that the value for the parameter had not been specified, and the changes were not saved.

When I used Microsoft Query (same place as the Data Connection Wizard), I was able to create parameters, specify a display name for them, and enter values each time the query was run. Bringing up the Connection Properties for that connection, the Parameters... button is enabled, and the parameters can be modified and used as I think you want.

I was also able to do this with an Access database. It seems reasonable that Microsoft Query could be used to create parameterized queries hitting other types of databases, but I can't easily test that right now.

Presumably this would work:

IF(compliment = 'set' OR compliment = 'Y' OR compliment = 1, 'Y', 'N') AS customer_compliment

children() only looks at the immediate children of the node, while find() traverses the entire DOM below the node, so children() should be faster given equivalent implementations. However, find() uses native browser methods, while children() uses JavaScript interpreted in the browser. In my experiments there isn't much performance difference in typical cases.

Which to use depends on whether you only want to consider the immediate descendants or all nodes below this one in the DOM, i.e., choose the appropriate method based on the results you desire, not the speed of the method. If performance is truly an issue, then experiment to find the best solution and use that (or see some of the benchmarks in the other answers here).

When this problem comes up with multiprocessing a simple solution is to switch from Pool to ThreadPool. This can be done with no change of code other than the import-

from multiprocessing.pool import ThreadPool as Pool

This works because ThreadPool shares memory with the main thread, rather than creating a new process- this means that pickling is not required.

The downside to this method is that python isn't the greatest language with handling threads- it uses something called the Global Interpreter Lock to stay thread safe, which can slow down some use cases here. However, if you're primarily interacting with other systems (running HTTP commands, talking with a database, writing to filesystems) then your code is likely not bound by CPU and won't take much of a hit. In fact I've found when writing HTTP/HTTPS benchmarks that the threaded model used here has less overhead and delays, as the overhead from creating new processes is much higher than the overhead for creating new threads.

So if you're processing a ton of stuff in python userspace this might not be the best method.

 <form name="myForm" ng-submit="submitForm()">
   <label data-ng-repeat="i in [1,2,3]"><input type="radio" name="test" ng-model="$parent.radioValue" value="{{i}}"/>{{i}}</label>
   <div>currently selected: {{radioValue}}</div>
   <button type="submit">Submit</button>
</form>

You can use INSERT... IGNORE syntax if you want to take no action when there's a duplicate record.

You can use REPLACE INTO syntax if you want to overwrite an old record with a new one with the same key.

Or, you can use INSERT... ON DUPLICATE KEY UPDATE syntax if you want to perform an update to the record instead when you encounter a duplicate.

Edit: Thought I'd add some examples.

Examples

Say you have a table named tbl with two columns, id and value. There is one entry, id=1 and value=1. If you run the following statements:

REPLACE INTO tbl VALUES(1,50);

You still have one record, with id=1 value=50. Note that the whole record was DELETED first however, and then re-inserted. Then:

INSERT IGNORE INTO tbl VALUES (1,10);

The operation executes successfully, but nothing is inserted. You still have id=1 and value=50. Finally:

INSERT INTO tbl VALUES (1,200) ON DUPLICATE KEY UPDATE value=200;

You now have a single record with id=1 and value=200.

The following example builds on MARTIN DE LA FUENTE SAAVEDRA's excellent work and accepted answer. In particular, two enumerations are introduced. The first allows for easy specification of how an elevated program is to be opened, and the second helps when errors need to be easily identified. Please note that if you want all command line arguments passed to the new process, sys.argv[0] should probably be replaced with a function call: subprocess.list2cmdline(sys.argv).

Actually there are many reasons for this issue. Mine was because of Invalid token passed. I was passing same token generated from one app and using same token in another app. Once token updated , it work for me.

Try this:

str.replace("\"", "\\\""); // (Escape backslashes and embedded double-quotes)

Or, use single-quotes to quote your search and replace strings:

str.replace('"', '\\"');   // (Still need to escape the backslash)

As pointed out by helmus, if the first parameter passed to .replace() is a string it will only replace the first occurrence. To replace globally, you have to pass a regex with the g (global) flag:

str.replace(/"/g, "\\\"");
// or
str.replace(/"/g, '\\"');

But why are you even doing this in JavaScript? It's OK to use these escape characters if you have a string literal like:

var str = "Dude, he totally said that \"You Rock!\"";

But this is necessary only in a string literal. That is, if your JavaScript variable is set to a value that a user typed in a form field you don't need to this escaping.

Regarding your question about storing such a string in an SQL database, again you only need to escape the characters if you're embedding a string literal in your SQL statement - and remember that the escape characters that apply in SQL aren't (usually) the same as for JavaScript. You'd do any SQL-related escaping server-side.

Though people have mentioned that you will need to use .container-fluid in this case but you will also have to remove the padding from bootstrap.

Let me give a few examples with some alternatives to avoid a ConcurrentModificationException.

Suppose we have the following collection of books

List<Book> books = new ArrayList<Book>();
books.add(new Book(new ISBN("0-201-63361-2")));
books.add(new Book(new ISBN("0-201-63361-3")));
books.add(new Book(new ISBN("0-201-63361-4")));

Collect and Remove

The first technique consists in collecting all the objects that we want to delete (e.g. using an enhanced for loop) and after we finish iterating, we remove all found objects.

ISBN isbn = new ISBN("0-201-63361-2");
List<Book> found = new ArrayList<Book>();
for(Book book : books){
    if(book.getIsbn().equals(isbn)){
        found.add(book);
    }
}
books.removeAll(found);

This is supposing that the operation you want to do is "delete".

If you want to "add" this approach would also work, but I would assume you would iterate over a different collection to determine what elements you want to add to a second collection and then issue an addAll method at the end.

Using ListIterator

If you are working with lists, another technique consists in using a ListIterator which has support for removal and addition of items during the iteration itself.

ListIterator<Book> iter = books.listIterator();
while(iter.hasNext()){
    if(iter.next().getIsbn().equals(isbn)){
        iter.remove();
    }
}

Again, I used the "remove" method in the example above which is what your question seemed to imply, but you may also use its add method to add new elements during iteration.

Using JDK >= 8

For those working with Java 8 or superior versions, there are a couple of other techniques you could use to take advantage of it.

You could use the new removeIf method in the Collection base class:

ISBN other = new ISBN("0-201-63361-2");
books.removeIf(b -> b.getIsbn().equals(other));

Or use the new stream API:

ISBN other = new ISBN("0-201-63361-2");
List<Book> filtered = books.stream()
                           .filter(b -> b.getIsbn().equals(other))
                           .collect(Collectors.toList());

In this last case, to filter elements out of a collection, you reassign the original reference to the filtered collection (i.e. books = filtered) or used the filtered collection to removeAll the found elements from the original collection (i.e. books.removeAll(filtered)).

Use Sublist or Subset

There are other alternatives as well. If the list is sorted, and you want to remove consecutive elements you can create a sublist and then clear it:

books.subList(0,5).clear();

Since the sublist is backed by the original list this would be an efficient way of removing this subcollection of elements.

Something similar could be achieved with sorted sets using NavigableSet.subSet method, or any of the slicing methods offered there.

Considerations:

What method you use might depend on what you are intending to do

• The collect and removeAl technique works with any Collection (Collection, List, Set, etc).
• The ListIterator technique obviously only works with lists, provided that their given ListIterator implementation offers support for add and remove operations.
• The Iterator approach would work with any type of collection, but it only supports remove operations.
• With the ListIterator/Iterator approach the obvious advantage is not having to copy anything since we remove as we iterate. So, this is very efficient.
• The JDK 8 streams example don't actually removed anything, but looked for the desired elements, and then we replaced the original collection reference with the new one, and let the old one be garbage collected. So, we iterate only once over the collection and that would be efficient.
• In the collect and removeAll approach the disadvantage is that we have to iterate twice. First we iterate in the foor-loop looking for an object that matches our removal criteria, and once we have found it, we ask to remove it from the original collection, which would imply a second iteration work to look for this item in order to remove it.
• I think it is worth mentioning that the remove method of the Iterator interface is marked as "optional" in Javadocs, which means that there could be Iterator implementations that throw UnsupportedOperationException if we invoke the remove method. As such, I'd say this approach is less safe than others if we cannot guarantee the iterator support for removal of elements.

(Taken from my comment)

pip won't handle system level dependencies. You'll have to apt-get install libfreetype6-dev before continuing. (It even says so right in your output. Try skimming over it for such errors next time, usually build outputs are very detailed)

You might also take a look at the Memoize decorator. You could probably get it to do what you want without too much modification.

From the documentation of InetAddress.getByName(String host):

The host name can either be a machine name, such as "java.sun.com", or a textual representation of its IP address. If a literal IP address is supplied, only the validity of the address format is checked.

So you can use it.

http://railscasts.com/episodes/279-understanding-the-asset-pipeline

This railscast (Rails Tutorial video on asset pipeline) helps a lot to explain the paths in assets pipeline as well. I found it pretty useful, and actually watched it a few times.

The solution I chose is @Lee McAlilly's above, but this railscast helped me to understand why it works. Hope it helps!

Consider an entity:

public class Foo{
private<user> user;
/* with getters and setters */
}

And consider an Business Logic class:

class Foo1{
List<User> user = new ArrayList<>();
user = foo.getUser();
}

Here the user and foo.getUser() share the same reference. But saving the two references creates a conflict.

The proper usage should be:

class Foo1 {
List<User> user = new ArrayList<>();
user.addAll(foo.getUser);
}

This avoids the conflict.

Use:

function console_log($data) {
    $bt = debug_backtrace();
    $caller = array_shift($bt);

    if (is_array($data))
        $dataPart = implode(',', $data);
    else
        $dataPart = $data;

    $toSplit = $caller['file'])) . ':' .
               $caller['line'] . ' => ' . $dataPart

    error_log(end(split('/', $toSplit));
}

you can use raiserror. Read more details here

--from MSDN

BEGIN TRY
    -- RAISERROR with severity 11-19 will cause execution to 
    -- jump to the CATCH block.
    RAISERROR ('Error raised in TRY block.', -- Message text.
               16, -- Severity.
               1 -- State.
               );
END TRY
BEGIN CATCH
    DECLARE @ErrorMessage NVARCHAR(4000);
    DECLARE @ErrorSeverity INT;
    DECLARE @ErrorState INT;

    SELECT 
        @ErrorMessage = ERROR_MESSAGE(),
        @ErrorSeverity = ERROR_SEVERITY(),
        @ErrorState = ERROR_STATE();

    -- Use RAISERROR inside the CATCH block to return error
    -- information about the original error that caused
    -- execution to jump to the CATCH block.
    RAISERROR (@ErrorMessage, -- Message text.
               @ErrorSeverity, -- Severity.
               @ErrorState -- State.
               );
END CATCH;

EDIT If you are using SQL Server 2012+ you can use throw clause. Here are the details.

All those ls/tail solutions work perfectly fine for files in a directory - ignoring subdirectories.

In order to include all files in your search (recursively), find can be used. gioele suggested sorting the formatted find output. But be careful with whitespaces (his suggestion doesn't work with whitespaces).

This should work with all file names:

find $DIR -type f -printf "%T@ %p\n" | sort -n | sed -r 's/^[0-9.]+\s+//' | tail -n 1 | xargs -I{} ls -l "{}"

This sorts by mtime, see man find:

%Ak    File's  last  access  time in the format specified by k, which is either `@' or a directive for the C `strftime' function.  The possible values for k are listed below; some of them might not be available on all systems, due to differences in `strftime' between systems.
       @      seconds since Jan. 1, 1970, 00:00 GMT, with fractional part.
%Ck    File's last status change time in the format specified by k, which is the same as for %A.
%Tk    File's last modification time in the format specified by k, which is the same as for %A.

So just replace %T with %C to sort by ctime.

I encountered this issue in my conda environment. The reason is that packages have been installed into two different folders, only one of which is recognised by the Python executable.

~/anaconda2/envs/[my_env]/site-packages ~/anaconda2/envs/[my_env]/lib/python2.7/site-packages

A proved solution is to add both folders to python path, using the following steps in command line (Please replace [my_env] with your own environment):

1. conda activate [my_env].
2. conda-develop ~/anaconda2/envs/[my_env]/site-packages
3. conda-develop ~/anaconda2/envs/[my_env]/lib/python2.7/site-packages (conda-develop is to add a .pth file to the folder so that the Python executable knows of this folder when searching for packages.)

To ensure this works, try to activate Python in this environment, and import the package that was not found.

@Entity is useful with model classes to denote that this is the entity or table

@Table is used to provide any specific name to your table if you want to provide any different name

Note: if you don't use @Table then hibernate consider that @Entity is your table name by default and @Entity must

@Entity    
@Table(name = "emp")     
public class Employee implements java.io.Serializable    
{

}

This is the most simple solution for me:

just the current date

$tStamp = Get-Date -format yyyy_MM_dd_HHmmss

current date with some months added

$tStamp = Get-Date (get-date).AddMonths(6).Date -Format yyyyMMdd

I used this:

$('.nav-list li.active').removeClass('active');
$(this).parent().addClass('active');

Since the active class is in the <li> element and what is clicked is the <a> element, the first line removes .active from all <li> and the second one (again, $(this) represents <a> which is the clicked element) adds .active to the direct parent, which is <li>.

Best answer I have found, it's working great.

Just go to your page on Facebook in the browser, right click, and click on "View source code", then find the page_id attribute: you have to use page_id here in this line after the last back-slash:

fb://page/pageID

For example:

Intent facebookAppIntent;
try {
    facebookAppIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("fb://page/1883727135173361"));
    startActivity(facebookAppIntent);
} catch (ActivityNotFoundException e) {
    facebookAppIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://facebook.com/CryOut-RadioTv-1883727135173361"));
    startActivity(facebookAppIntent);
}

$('#thisElement').find('.classToSelect') will find any descendents of #thisElement with class classToSelect.

method does not work for me in the case of Xilinx xsdk, because as pointed out by @jeb in the comments below it is actaully a bat file.

so what does not work de-facto is

start "" BatToExecute

I am trying to open xsdk like that and it opens a separate cmd that needs to be closed and xsdk can run on its own

Before launching xsdk I run (source) the Env / Paths (with settings64.bat) so that xsdk.bat command gets recognized (simply as xsdk, withoitu the .bat)

what works with .bat

call BatToExecute

The answer here is not clear, so I wanted to add more detail.

Using the link provided above, I performed the following step.

In my XML config manager I changed the "Provider" to SQLOLEDB.1 rather than SQLNCLI.1. This got me past this error.

This information is available at the link the OP posted in the Answer.

If you want to use a library, a quick google search for csv and django reveals two libraries - django-csvimport and django-adaptors. Let's read what they have to say about themselves...

• django-adaptors:

Django adaptor is a tool which allow you to transform easily a CSV/XML file into a python object or a django model instance.

• django-importcsv:

django-csvimport is a generic importer tool to allow the upload of CSV files for populating data.

The first requires you to write a model to match the csv file, while the second is more of a command-line importer, which is a huge difference in the way you work with them, and each is good for a different type of project.

So which one to use? That depends on which of those will be better suited for your project in the long run.

However, you can also avoid a library altogether, by writing your own django script to import your csv file, something along the lines of (warning, pseudo-code ahead):

# open file & create csvreader
import csv, yada yada yada

# import the relevant model
from myproject.models import Foo

#loop:
for line in csv file:
     line = parse line to a list
     # add some custom validation\parsing for some of the fields

     foo = Foo(fieldname1=line[1], fieldname2=line[2] ... etc. )
     try:
         foo.save()
     except:
         # if the're a problem anywhere, you wanna know about it
         print "there was a problem with line", i 

It's super easy. Hell, you can do it interactively through the django shell if it's a one-time import. Just - figure out what you want to do with your project, how many files do you need to handle and then - if you decide to use a library, try figuring out which one better suits your needs.

SELECT contendernum,totals, RANK() OVER (ORDER BY totals ASC) AS xRank FROM
(
SELECT ContenderNum ,SUM(Criteria1+Criteria2+Criteria3+Criteria4) AS totals
FROM dbo.Cat1GroupImpersonation
 GROUP BY ContenderNum
) AS a

Copy the diff file to the root of your repository, and then do:

git apply yourcoworkers.diff

More information about the apply command is available on its man page.

By the way: A better way to exchange whole commits by file is the combination of the commands git format-patch on the sender and then git am on the receiver, because it also transfers the authorship info and the commit message.

If the patch application fails and if the commits the diff was generated from are actually in your repo, you can use the -3 option of apply that tries to merge in the changes.

It also works with Unix pipe as follows:

git diff d892531 815a3b5 | git apply

ytd2 is a fully functional YouTube video downloader. Check out its source code if you want to see how it's done.

Alternatively, you can also call an external process like youtube-dl to do the job. This is probably the easiest solution but it isn't in "pure" Java.

Include required imports and you can make ur decision in handleError method Error status will give the error code

import { HttpClient, HttpErrorResponse } from '@angular/common/http';
import {Observable, throwError} from "rxjs/index";
import { catchError, retry } from 'rxjs/operators';
import {ApiResponse} from "../model/api.response";
import { TaxType } from '../model/taxtype.model'; 

private handleError(error: HttpErrorResponse) {
if (error.error instanceof ErrorEvent) {
  // A client-side or network error occurred. Handle it accordingly.
  console.error('An error occurred:', error.error.message);
} else {
  // The backend returned an unsuccessful response code.
  // The response body may contain clues as to what went wrong,
  console.error(
    `Backend returned code ${error.status}, ` +
    `body was: ${error.error}`);
}
// return an observable with a user-facing error message
return throwError(
  'Something bad happened; please try again later.');
  };

  getTaxTypes() : Observable<ApiResponse> {
return this.http.get<ApiResponse>(this.baseUrl).pipe(
  catchError(this.handleError)
);
  }

you can use TextBlock control and assign the text property.

Your error is caused by these:

Dim oTable As Table, oRow As Row,

These types, Table and Row are not variable types native to Excel. You can resolve this in one of two ways:

1. Include a reference to the Microsoft Word object model. Do this from Tools | References, then add reference to MS Word. While not strictly necessary, you may like to fully qualify the objects like Dim oTable as Word.Table, oRow as Word.Row. This is called early-binding.
2. Alternatively, to use late-binding method, you must declare the objects as generic Object type: Dim oTable as Object, oRow as Object. With this method, you do not need to add the reference to Word, but you also lose the intellisense assistance in the VBE.

I have not tested your code but I suspect ActiveDocument won't work in Excel with method #2, unless you properly scope it to an instance of a Word.Application object. I don't see that anywhere in the code you have provided. An example would be like:

Sub DeleteEmptyRows()
Dim wdApp as Object
Dim oTable As Object, As Object, _
TextInRow As Boolean, i As Long

Set wdApp = GetObject(,"Word.Application")

Application.ScreenUpdating = False

For Each oTable In wdApp.ActiveDocument.Tables

This solved my problem. You should select Properties, Right-Click, Source Control and Get Specific Version.

git push origin --delete origin/test 

should work as well

From Microsoft:

These uses for DateTimeOffset values are much more common than those for DateTime values. As a result, DateTimeOffset should be considered the default date and time type for application development.

_{source: "Choosing Between DateTime, DateTimeOffset, TimeSpan, and TimeZoneInfo", MSDN}

We use DateTimeOffset for nearly everything as our application deals with particular points in time (e.g. when a record was created/updated). As a side note, we use DATETIMEOFFSET in SQL Server 2008 as well.

I see DateTime as being useful when you want to deal with dates only, times only, or deal with either in a generic sense. For example, if you have an alarm that you want to go off every day at 7 am, you could store that in a DateTime utilizing a DateTimeKind of Unspecified because you want it to go off at 7am regardless of DST. But if you want to represent the history of alarm occurrences, you would use DateTimeOffset.

Use caution when using a mix of DateTimeOffset and DateTime especially when assigning and comparing between the types. Also, only compare DateTime instances that are the same DateTimeKind because DateTime ignores timezone offset when comparing.

We have two problems to cope with.

1. You cannot provide a sensible GetHashCode() if any field in the object can be changed. Also often a object will NEVER be used in a collection that depends on GetHashCode(). So the cost of implementing GetHashCode() is often not worth it, or it is not possible.

2. If someone puts your object in a collection that calls GetHashCode() and you have overrided Equals() without also making GetHashCode() behave in a correct way, that person may spend days tracking down the problem.

Therefore by default I do.

public class Foo
{
    public int FooId { get; set; }
    public string FooName { get; set; }

    public override bool Equals(object obj)
    {
        Foo fooItem = obj as Foo;

        if (fooItem == null)
        {
           return false;
        }

        return fooItem.FooId == this.FooId;
    }

    public override int GetHashCode()
    {
        // Some comment to explain if there is a real problem with providing GetHashCode() 
        // or if I just don't see a need for it for the given class
        throw new Exception("Sorry I don't know what GetHashCode should do for this class");
    }
}

You want an entity known as a cross mark:

http://www.fileformat.info/info/unicode/char/274c/index.htm

The code for it is ❌ and it displays like ❌

If you want a perfectly centered cross mark, like this:

try the following CSS:

div {
    height: 100px;
    width: 100px;
    background-color: #FA6900;
    border-radius: 5px;
    position: relative;
}

div:after {
    position: absolute;
    top: 0;
    bottom: 0;
    left: 0;
    right: 0;
    content: "\274c"; /* use the hex value here... */
    font-size: 50px; 
    color: #FFF;
    line-height: 100px;
    text-align: center;
}

See Demo Fiddle

Cross-Browser Issue

The cross-mark entity does not display with Safari or Chrome. However, the same entity displays well in Firefox, IE and Opera.

It is safe to use the smaller but similarly shaped multiplication sign entity, × which displays as ×.

For .NET 4.6.2 or lower, .NET Core 1.x, and .NET Standard 1.x you need to install the NuGet package System.ValueTuple:

Install-Package "System.ValueTuple"

Or using a package reference in VS 2017:

<PackageReference Include="System.ValueTuple" Version="4.4.0" />

.NET Framework 4.7, .NET Core 2.0, and .NET Standard 2.0 include these types.

You do not have to install another version of Xampp. I've managed to use PHP 5.6 on my Xampp PHP 7 version. Here is what you need to do to make it works:

1. Raname (backup) <XAMPP_DIR>\php to <XAMPP_DIR>\php~7
2. Copy (backup) <XAMPP_DIR>\apache\conf\extra\httpd-xampp.conf to <XAMPP_DIR>\apache\conf\extra\httpd-xampp~7.conf
3. Download PHP5 and unpack it to <XAMPP_DIR>\php
4. Edit <XAMPP_DIR>\apache\conf\extra\httpd-xampp.conf and change all php5 occurrences to php7. You need to change php7apache2_4.dll to php5apache2_4.dll, php7ts.dll to php5ts.dll and php7_module to php5_module
5. Ensure all your paths are correct like extension_dir in php.ini.

Restart Apache and voila.

SELECT
    o.name
FROM
    sys.sql_modules sm
INNER JOIN sys.objects o ON
    o.object_id = sm.object_id
WHERE
    sm.definition LIKE '%<table name>%'

Just keep in mind that this will also turn up SPs where the table name is in the comments or where the table name is a substring of another table name that is being used. For example, if you have tables named "test" and "test_2" and you try to search for SPs with "test" then you'll get results for both.

lastInsertId() only work after the INSERT query.

Correct:

$stmt = $this->conn->prepare("INSERT INTO users(userName,userEmail,userPass) 
                              VALUES(?,?,?);");
$sonuc = $stmt->execute([$username,$email,$pass]);
$LAST_ID = $this->conn->lastInsertId();

Incorrect:

$stmt = $this->conn->prepare("SELECT * FROM users");
$sonuc = $stmt->execute();
$LAST_ID = $this->conn->lastInsertId(); //always return string(1)=0

Globbing uses brackets, hence the need to escape them with a slash \. Alternatively, the following command-line switch will disable globbing:

--globoff (or the short-option version: -g)

Ex:

curl --globoff https://www.google.com?test[]=1

Do you specify a user name and password to log on? What exactly is your complete command line?

If you're running on your own box, you can either specify a username/password, or use the -E parameter to log on with your Windows credentials (if those are permitted in your SQL server installation).

Marc

If you want to do it from the command line and not built into the script itself, use:

.\myscript.ps1 | Out-File c:\output.csv

pip list shows ALL installed packages.

pip freeze shows packages YOU installed via pip (or pipenv if using that tool) command in a requirements format.

Remark below that setuptools, pip, wheel are installed when pipenv shell creates my virtual envelope. These packages were NOT installed by me using pip:

test1 % pipenv shell
Creating a virtualenv for this project…

Now review & compare the output of the respective commands where I've only installed cool-lib and sampleproject (of which peppercorn is a dependency):

    return 0;
}

I had the problem, that the classpath was broken somehow.

So right click on the project in Package explorer > Plug-in tools > Update classpath... did it for me

def LongestSubString(s1,s2):
    left = 0
    right =len(s2)
    while(left<right):
        if(s2[left] not in s1):
            left = left+1
        else:
            if(s2[left:right] not in s1):
                right = right - 1
            else:
                return(s2[left:right])

s1 = "pineapple"
s2 = "applc"
print(LongestSubString(s1,s2))

Perhaps not in the context that you have it, but you could use

SELECT DISTINCT col1,
PERCENTILE_CONT(col2) WITHIN GROUP (ORDER BY col2) OVER (PARTITION BY col1),
PERCENTILE_CONT(col2) WITHIN GROUP (ORDER BY col2) OVER (PARTITION BY col1, col3),
FROM TableA

You would use this to return different levels of aggregation returned in a single row. The use case would be for when a single grouping would not suffice all of the aggregates needed.

Print datatable rows with column

Here is solution 

DataTable datatableinfo= new DataTable();

// Fill data table 

//datatableinfo=fill by function or get data from database

//Print data table with rows and column


for (int j = 0; j < datatableinfo.Rows.Count; j++)
{
    for (int i = 0; i < datatableinfo.Columns.Count; i++)    
        {    
            Console.Write(datatableinfo.Columns[i].ColumnName + " ");    
            Console.WriteLine(datatableinfo.Rows[j].ItemArray[i]+" "); 
        }
}


Ouput :
ColumnName - row Value
ColumnName - row Value
ColumnName - row Value
ColumnName - row Value

If You want nice format like: 0:00:00 use str_pad() as @Gardner.

It's difficult to tell what you're actually trying to do and if this is what you really need but you might also use a callback:

function myFunction(value1,callback)
{
     //Do stuff and 

     if(typeof callback == 'function'){
        callback(somevalue2,somevalue3);
    }
}


myFunction("1", function(value2, value3){
    if(value2 && value3)
    {
    //Do some stuff
    }
});

This will get you the tables in foreign key order and avoid dropping some of the tables created by SQL Server. The t.Ordinal value will slice the tables into dependency layers.

    SELECT OBJECT_SCHEMA_NAME(so.object_id) AS SchemaName,

Date is not in any time zone (it is a millisecond office from a defined moment in time same for everyone), but underlying (R)DBs generally store timestamps in political format (year, month, day, hour, minute, second, ...) that is time-zone sensitive.

To be serious, Hibernate MUST be allow being told within some form of mapping that the DB date is in such-and-such timezone so that when it loads or stores it it does not assume its own...

The simplest way to read each line of a file into a bash array is this:

IFS=$'\n' read -d '' -r -a lines < /etc/passwd

Now just index in to the array lines to retrieve each line, e.g.

printf "line 1: %s\n" "${lines[0]}"
printf "line 5: %s\n" "${lines[4]}"

# all lines
echo "${lines[@]}"

edit (not by the author): There is a comprehensive list of IoC frameworks available at https://github.com/quozd/awesome-dotnet/blob/master/README.md#ioc:

• Castle Windsor - Castle Windsor is best of breed, mature Inversion of Control container available for .NET and Silverlight
• Unity - Lightweight extensible dependency injection container with support for constructor, property, and method call injection
• Autofac - An addictive .NET IoC container
• DryIoc - Simple, fast all fully featured IoC container.
• Ninject - The ninja of .NET dependency injectors
• StructureMap - The original IoC/DI Container for .Net
• Spring.Net - Spring.NET is an open source application framework that makes building enterprise .NET applications easier
• LightInject - A ultra lightweight IoC container
• Simple Injector - Simple Injector is an easy-to-use Dependency Injection (DI) library for .NET 4+ that supports Silverlight 4+, Windows Phone 8, Windows 8 including Universal apps and Mono.
• Microsoft.Extensions.DependencyInjection - The default IoC container for ASP.NET Core applications.
• Scrutor - Assembly scanning extensions for Microsoft.Extensions.DependencyInjection.
• VS MEF - Managed Extensibility Framework (MEF) implementation used by Visual Studio.
• TinyIoC - An easy to use, hassle free, Inversion of Control Container for small projects, libraries and beginners alike.

Original answer follows.

I suppose I might be being a bit picky here but it's important to note that DI (Dependency Injection) is a programming pattern and is facilitated by, but does not require, an IoC (Inversion of Control) framework. IoC frameworks just make DI much easier and they provide a host of other benefits over and above DI.

That being said, I'm sure that's what you were asking. About IoC Frameworks; I used to use Spring.Net and CastleWindsor a lot, but the real pain in the behind was all that pesky XML config you had to write! They're pretty much all moving this way now, so I have been using StructureMap for the last year or so, and since it has moved to a fluent config using strongly typed generics and a registry, my pain barrier in using IoC has dropped to below zero! I get an absolute kick out of knowing now that my IoC config is checked at compile-time (for the most part) and I have had nothing but joy with StructureMap and its speed. I won't say that the others were slow at runtime, but they were more difficult for me to setup and frustration often won the day.

Update

I've been using Ninject on my latest project and it has been an absolute pleasure to use. Words fail me a bit here, but (as we say in the UK) this framework is 'the Dogs'. I would highly recommend it for any green fields projects where you want to be up and running quickly. I got all I needed from a fantastic set of Ninject screencasts by Justin Etheredge. I can't see that retro-fitting Ninject into existing code being a problem at all, but then the same could be said of StructureMap in my experience. It'll be a tough choice going forward between those two, but I'd rather have competition than stagnation and there's a decent amount of healthy competition out there.

Other IoC screencasts can also be found here on Dimecasts.

And on my Windows 7 machine it is here:

C:\Program Files (x86)\Microsoft SDKs\Windows\v8.1A\bin\NETFX 4.5.1 Tools

Note that the file wsdl.exe is portable, in that you can copy it to another windows machine and it works. I have not tried to see if the 4.5 exe will work on a machine that only have .NET 2.0, but this would be interesting to know.

To use

import styled from 'styled-components/native';
import { crossPlatformElevation } from "../../lib/stylingTools";

export const ContentContainer = styled.View`

There is also a combination, you can use a return value with a recordset:

--Stored Procedure--

CREATE PROCEDURE [TestProc]

AS
BEGIN

    DECLARE @Temp TABLE
    (
        [Name] VARCHAR(50)
    )

    INSERT INTO @Temp VALUES ('Mark') 
    INSERT INTO @Temp VALUES ('John') 
    INSERT INTO @Temp VALUES ('Jane') 
    INSERT INTO @Temp VALUES ('Mary') 

    -- Get recordset
    SELECT * FROM @Temp

    DECLARE @ReturnValue INT
    SELECT @ReturnValue = COUNT([Name]) FROM @Temp

    -- Return count
    RETURN @ReturnValue

END

--Calling Code--

DECLARE @SelectedValue int
EXEC @SelectedValue = [TestProc] 

SELECT @SelectedValue

--Results--

If you are looking for paragraph indent then you can go for 'text-indent' declaration in CSS.

<!DOCTYPE html>   
 <html>
        <head>
            <style>
                p { text-indent: 50px; }
            </style>
        </head>
        <body>
            <p>This paragraph will be indented by 50px. I hope this helps! Only the first line will be indented.</p>
        </body>
    </html>

There are several approaches.

One is to use a non-capturing group in the regex: (?:/(?P<title>[a-zA-Z]+)/)?
Making a Regex Django URL Token Optional

Another, easier to follow way is to have multiple rules that matches your needs, all pointing to the same view.

urlpatterns = patterns('',
    url(r'^project_config/$', views.foo),
    url(r'^project_config/(?P<product>\w+)/$', views.foo),
    url(r'^project_config/(?P<product>\w+)/(?P<project_id>\w+)/$', views.foo),
)

Keep in mind that in your view you'll also need to set a default for the optional URL parameter, or you'll get an error:

def foo(request, optional_parameter=''):
    # Your code goes here

armhf stands for "arm hard float", and is the name given to a debian port for arm processors (armv7+) that have hardware floating point support.

On the beaglebone black, for example:

:~$ dpkg --print-architecture
armhf

Although other commands (such as uname -a or arch) will just show armv7l

:~$ cat /proc/cpuinfo 
processor       : 0
model name      : ARMv7 Processor rev 2 (v7l)
BogoMIPS        : 995.32
Features        : half thumb fastmult vfp edsp thumbee neon vfpv3 tls
...

The vfpv3 listed under Features is what refers to the floating point support.

Incidentally, armhf, if your processor supports it, basically supersedes Raspbian, which if I understand correctly was mainly a rebuild of armhf with work arounds to deal with the lack of floating point support on the original raspberry pi's. Nowdays, of course, there's a whole ecosystem build up around Raspbian, so they're probably not going to abandon it. However, this is partly why the beaglebone runs straight debian, and that's ok even if you're used to Raspbian, unless you want some of the special included non-free software such as Mathematica.

Responding to an earlier comment, you can change the background by variable in the "container" example if the CSS is in your php page and not in the css style sheet.

$bgimage = '[some image url];
background-image: url('<?php echo $bgimage; ?>');

I realise this is an old question, but another possible consideration depending on your exact requirements is that validating on https://validator.w3.org/ generates warnings as follows:

Warning: The form role is unnecessary for element form.

You haven't specified the database. If it is one that allows analytical functions it may be faster to use this approach than the GROUP BY one(definitely faster in Oracle, most likely faster in the late SQL Server editions, don't know about others).

Syntax in SQL Server would be:

SELECT c.*, p.*
FROM customer c INNER JOIN 
     (SELECT RANK() OVER (PARTITION BY customer_id ORDER BY date DESC) r, *
             FROM purchase) p
ON (c.id = p.customer_id)
WHERE p.r = 1

If you want to skip running and compiling tests:

mvn -Dmaven.test.skip=true install

If you want to compile but not run tests:

mvn install -DskipTests

I did not have the /usr/local/Frameworks folder, so this fixed it for me

sudo mkdir -p /usr/local/Frameworks
sudo chown -R $(whoami) /usr/local/Frameworks

The first line creates a new Frameworks folder for homebrew (brew) to use. The second line gives that folder your current user permissions, which are sufficient.

Used commands are as follows:

mkdir - make directories [-p no error if existing, make parent directories as needed]

chown - change file owner and group [-R operate on files and directories recursively]

whoami - print effective userid

I have OSX High Sierra

Every printer is different but 0.25" (6.35 mm) is a safe bet.

Your class doesn't have a __init__(), so by the time it's instantiated, the attribute atoms is not present. You'd have to do C.setdata('something') so C.atoms becomes available.

>>> C = Residues()
>>> C.atoms.append('thing')

Traceback (most recent call last):
  File "<pyshell#84>", line 1, in <module>
    B.atoms.append('thing')
AttributeError: Residues instance has no attribute 'atoms'

>>> C.setdata('something')
>>> C.atoms.append('thing')   # now it works
>>> 

Unlike in languages like Java, where you know at compile time what attributes/member variables an object will have, in Python you can dynamically add attributes at runtime. This also implies instances of the same class can have different attributes.

To ensure you'll always have (unless you mess with it down the line, then it's your own fault) an atoms list you could add a constructor:

def __init__(self):
    self.atoms = []

Sorry EMS, but I actually just got another response from the matplotlib mailling list (Thanks goes out to Benjamin Root).

The code I am looking for is adjusting the savefig call to:

fig.savefig('samplefigure', bbox_extra_artists=(lgd,), bbox_inches='tight')
#Note that the bbox_extra_artists must be an iterable

This is apparently similar to calling tight_layout, but instead you allow savefig to consider extra artists in the calculation. This did in fact resize the figure box as desired.

import matplotlib.pyplot as plt
import numpy as np

plt.gcf().clear()
x = np.arange(-2*np.pi, 2*np.pi, 0.1)
fig = plt.figure(1)
ax = fig.add_subplot(111)
ax.plot(x, np.sin(x), label='Sine')
ax.plot(x, np.cos(x), label='Cosine')
ax.plot(x, np.arctan(x), label='Inverse tan')
handles, labels = ax.get_legend_handles_labels()
lgd = ax.legend(handles, labels, loc='upper center', bbox_to_anchor=(0.5,-0.1))
text = ax.text(-0.2,1.05, "Aribitrary text", transform=ax.transAxes)
ax.set_title("Trigonometry")
ax.grid('on')
fig.savefig('samplefigure', bbox_extra_artists=(lgd,text), bbox_inches='tight')

This produces:

[edit] The intent of this question was to completely avoid the use of arbitrary coordinate placements of arbitrary text as was the traditional solution to these problems. Despite this, numerous edits recently have insisted on putting these in, often in ways that led to the code raising an error. I have now fixed the issues and tidied the arbitrary text to show how these are also considered within the bbox_extra_artists algorithm.

If you have a query with a lot of criteria, it can be tricky to remember what each one does. I add a text field into the original table - call it "comments" or "documentation". Then I include it in the query with a comment for each criteria.

Comments need to be written like like this so that all relevant rows are returned. Unfortunately, as I'm a new poster, I can't add a screenshot!

So here goes without

Field:   | Comment              |ContractStatus     | ProblemDealtWith | ...... |

Table:   | ElecContracts        |ElecContracts      | ElecContracts    | ...... |

Sort:  

Show:  

Criteria | <> "all problems are | "objection" Or |

         | picked up with this  | "rejected" Or  |

         | criteria" OR Is Null | "rolled"       |

         | OR ""

<> tells the query to choose rows that are not equal to the text you entered, otherwise it will only pick up fields that have text equal to your comment i.e. none!

" " enclose your comment in quotes

OR Is Null OR "" tells your query to include any rows that have no data in the comments field , otherwise it won't return anything!

if you running docker under docker-machine?

execute to get ip:

docker-machine ip <machine>

returns the ip for the machine and try connect mysql:

mysql -h<docker-machine-ip>

First of let's your image name is myimage. So what you have to do is that go to Drawable and save the image name myimage.

Now assume you know only image name and you need to access it. Use below snippet to access it,

what you did is correct , ensure you saved image name you are going to use inside coding.

public static int getResourceId(Context context, String name, String resourceType) {
    return context.getResources().getIdentifier(toResourceString(name), resourceType, context.getPackageName());
}

private static String toResourceString(String name) {
    return name.replace("(", "")
               .replace(")", "")
               .replace(" ", "_")
               .replace("-", "_")
               .replace("'", "")
               .replace("&", "")
               .toLowerCase();
}

In addition to it you should ensure that there is no empty spaces and case sensitives

Did you mean "Complex" as in complex number with real and imaginary parts? This seems unlikely, so if not you'd have to give an example since "complex" means nothing specific in terms of the C language.

You will get a direct memory copy of the structure; whether that is what you want depends on the structure. For example if the structure contains a pointer, both copies will point to the same data. This may or may not be what you want; that is down to your program design.

To perform a 'smart' copy (or a 'deep' copy), you will need to implement a function to perform the copy. This can be very difficult to achieve if the structure itself contains pointers and structures that also contain pointers, and perhaps pointers to such structures (perhaps that's what you mean by "complex"), and it is hard to maintain. The simple solution is to use C++ and implement copy constructors and assignment operators for each structure or class, then each one becomes responsible for its own copy semantics, you can use assignment syntax, and it is more easily maintained.

The simplest way to append more text to the end of a file would be to use:

with open('/path/to/file', 'a+') as file:
    file.write("Additions to file")
file.close()

The a+ in the open(...) statement instructs to open the file in append mode and allows read and write access.

It is also always good practice to use file.close() to close any files that you have opened once you are done using them.

Image Upload for Summernote v0.8.1

for large images

$('#summernote').summernote({
    height: ($(window).height() - 300),
    callbacks: {
        onImageUpload: function(image) {
            uploadImage(image[0]);
        }
    }
});

function uploadImage(image) {
    var data = new FormData();
    data.append("image", image);
    $.ajax({
        url: 'Your url to deal with your image',
        cache: false,
        contentType: false,
        processData: false,
        data: data,
        type: "post",
        success: function(url) {
            var image = $('<img>').attr('src', 'http://' + url);
            $('#summernote').summernote("insertNode", image[0]);
        },
        error: function(data) {
            console.log(data);
        }
    });
}

I think you should tranfer image in base64 to image with blob, because when you use base64 image, it take a lot of log lines or a lot of line will send to server. With blob, it only the file. You can use this code bellow:

dataURLtoBlob = (dataURL) ->
  # Decode the dataURL
  binary = atob(dataURL.split(',')[1])
  # Create 8-bit unsigned array
  array = []
  i = 0
  while i < binary.length
    array.push binary.charCodeAt(i)
    i++
  # Return our Blob object
  new Blob([ new Uint8Array(array) ], type: 'image/png')

And canvas code here:

canvas = document.getElementById('canvas')
file = dataURLtoBlob(canvas.toDataURL())

After that you can use ajax with Form:

  fd = new FormData
  # Append our Canvas image file to the form data
  fd.append 'image', file
  $.ajax
    type: 'POST'
    url: '/url-to-save'
    data: fd
    processData: false
    contentType: false

To add my 2 cents. To mock specific http request methods either Get or Post. This worked for me.

mockHttpMessageHandler.Protected().Setup<Task<HttpResponseMessage>>("SendAsync", ItExpr.Is<HttpRequestMessage>(a => a.Method == HttpMethod.Get), ItExpr.IsAny<CancellationToken>())
                                                .Returns(Task.FromResult(new HttpResponseMessage()
                                                {
                                                    StatusCode = HttpStatusCode.OK,
                                                    Content = new StringContent(""),
                                                })).Verifiable();

According to https://bugzilla.mozilla.org/show_bug.cgi?id=592284, the pref network.http.connection-retry-timeout controls the amount of time in ms (Milliseconds !) to wait for success on the initial connection before beginning the second one. Setting it to 0 disables the parallel connection.

The most pythonic way would be to use a list comprehension:

l = [2*x for x in l]

If you need to do this for a large number of integers, use numpy arrays:

l = numpy.array(l, dtype=int)*2

A final alternative is to use map

l = list(map(lambda x:2*x, l))

// sample code for addition using JOptionPane

import javax.swing.JOptionPane;

public class Addition {

    public static void main(String[] args) {

        String firstNumber = JOptionPane.showInputDialog("Input <First Integer>");

        String secondNumber = JOptionPane.showInputDialog("Input <Second Integer>");

        int num1 = Integer.parseInt(firstNumber);
        int num2 = Integer.parseInt(secondNumber);
        int sum = num1 + num2;
        JOptionPane.showMessageDialog(null, "Sum is" + sum, "Sum of two Integers", JOptionPane.PLAIN_MESSAGE);
    }
}

I have created a data frame in a for loop with the help of a temporary empty data frame. Because for every iteration of for loop, a new data frame will be created thereby overwriting the contents of previous iteration.

Hence I need to move the contents of the data frame to the empty data frame that was created already. It's as simple as that. We just need to use .append function as shown below :

temp_df = pd.DataFrame() #Temporary empty dataframe
for sent in Sentences:
    New_df = pd.DataFrame({'words': sent.words}) #Creates a new dataframe and contains tokenized words of input sentences
    temp_df = temp_df.append(New_df, ignore_index=True) #Moving the contents of newly created dataframe to the temporary dataframe

Outside the for loop, you can copy the contents of the temporary data frame into the master data frame and then delete the temporary data frame if you don't need it

There are probably better options, but I use and kind of like TextWrangler for basic hex editing. File -> hex Dump File

An alternative in Java 8:

String[] strings = list.stream().toArray(String[]::new);

(There was already basically the same question "create a git symbolic ref in remote repository", which received no universal answer.)

But there are a specific answers for various git "farms" (where multiple users can manage git repos through a restricted interface: via http and ssh): http://Github.com, http://Gitorious.org, http://repo.or.cz, Girar (http://git.altlinux.org).

These specific answers might be useful for those reading this page and thinking about these specific services.

• Now they have a drop-down menu for selecting the HEAD branch at http://repo.or.cz (example: http://repo.or.cz/editproj.cgi?name=for-me-and-for-all_imz.git);
• and at http://gitorious.org, too (look somewhere in the settings);
• and at http://GitHub.com: admin > Default Branch > (choose something) (thanks to @srcspider's answer);
• Since v2.6, the default branch can be set in the Web interface under 'Projects' > 'List' > > 'Branches'. In v2.12, Gerrit added a new set-head command that can be used over ssh.
• and in Girar (running on http://git.altlinux.org to build packages for ALT's distro), one can the ssh interface for this: $ ssh git.alt help | fgrep branch default-branch <path to git repository> [<branch>] $ for example ssh git.alt default-branch packages/autosshd.git sisyphus to change the HEAD in the remote repo autosshd.git to point to the sisyphus branch.

Check out the Magick++ API to ImageMagick.

Another great option is the free V-Tools addin for Microsoft Access. Among other helpful tools it has a form to edit and save the Import/Export specifications.

Note: As of version 1.83, there is a bug in enumerating the code pages on Windows 10. (Apparently due to a missing/changed API function in Windows 10) The tools still works great, you just need to comment out a few lines of code or step past it in the debug window.

This has been a real life-saver for me in editing a complex import spec for our online orders.

Let's polyfill:

if(!AbortController){
  class AbortController {
    constructor() {
      this.aborted = false;
      this.signal = this.signal.bind(this);
    }
    signal(abortFn, scope) {
      if (this.aborted) {
        abortFn.apply(scope, { name: 'AbortError' });
        this.aborted = false;
      } else {
        this.abortFn = abortFn.bind(scope);
      }
    }
    abort() {
      if (this.abortFn) {
        this.abortFn({ reason: 'canceled' });
        this.aborted = false;
      } else {
        this.aborted = true;
      }
    }
  }

  const originalFetch = window.fetch;

  const customFetch = (url, options) => {
    const { signal } = options || {};

    return new Promise((resolve, reject) => {
      if (signal) {
        signal(reject, this);
      }
      originalFetch(url, options)
        .then(resolve)
        .catch(reject);
    });
  };

  window.fetch = customFetch;
}

Please have in mind that the code is not tested! Let me know if you have tested it and something didn't work. It may give you warnings that you try to overwrite the 'fetch' function from the JavaScript official library.

You can use the @NamedEntityGraph annotation to your entity to create a loadable query that set which collections you want to load on your query.

The main advantage of this choice is that hibernate makes one single query to retrieve the entity and its collections and only when you choose to use this graph, like this:

Entity configuration

@Entity
@NamedEntityGraph(name = "graph.myEntity.addresesAndPersons", 
attributeNodes = {
    @NamedAttributeNode(value = "addreses"),
    @NamedAttributeNode(value = "persons"
})

Usage

public MyEntity findNamedGraph(Object id, String namedGraph) {
        EntityGraph<MyEntity> graph = em.getEntityGraph(namedGraph);

        Map<String, Object> properties = new HashMap<>();
        properties.put("javax.persistence.loadgraph", graph);

        return em.find(MyEntity.class, id, properties);
    }

You'd better consider using Message Queues instead of advised methods. I'm sure this will be better solution, although it requires a little more job than just sending a request.

Save below in a test.bat and It'll work for you:

@echo off

net use Z: \\server\SharedFolderName password /user:domain\Username /persistent:yes

/persistent:yes flag will tell the computer to automatically reconnect this share on logon. Otherwise, you need to run the script again during each boot to map the drive.

For Example:

net use Z: \\WindowsServer123\g$ P@ssw0rd /user:Mynetdomain\Sysadmin /persistent:yes

All the above solutions are good, but I like @Steve's and @bejota's the best as they do not involve fancy calls and are universal.

By universal I mean that works with any type of axes including GeoAxes. For example, it you have projected axes for mapping:

projection = cartopy.crs.UTM(zone='17N')
ax = plt.axes(projection=projection)
im = ax.imshow(np.arange(200).reshape((20, 10)))

a call to

cax = divider.append_axes("right", size=width, pad=pad)

will fail with: KeyException: map_projection

Therefore, the only universal way of dealing colorbar size with all types of axes is:

ax.colorbar(im, fraction=0.046, pad=0.04)

Work with fraction from 0.035 to 0.046 to get your best size. However, the values for the fraction and paddig will need to be adjusted to get the best fit for your plot and will differ depending if the orientation of the colorbar is in vertical position or horizontal.

With REGEXP_SUBSTR is as simple as:

SELECT REGEXP_SUBSTR(t.column_one, '[^ ]+', 1, 1) col_one,
       REGEXP_SUBSTR(t.column_one, '[^ ]+', 1, 2) col_two
FROM YOUR_TABLE t;

        $('#myModal').on('hidden.bs.modal', function () {
            $(this).removeData('modal');
        });

This one works for me.

There are 'META-INF/spring.schemas' files in various Spring jars containing the mappings for the URLs that are intercepted for local resolution. If a particular xsd URL is not listed in these files (for example after switching from http to https) Spring tries to load schemas from the Internet and if the system has no Internet connection it fails and causes this error.

This can be the case with Spring Security v5.2 and up where there is no http mapping for the xsd file.

To fix it change

xsi:schemaLocation="
    http://www.springframework.org/schema/beans     
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/security  
    http://www.springframework.org/schema/security/spring-security.xsd"

to

xsi:schemaLocation="
    http://www.springframework.org/schema/beans     
    https://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/security  
    https://www.springframework.org/schema/security/spring-security.xsd"

Note that only actual xsd URL was modified from http to https (only two places above).

Tyson's answer is correct for changing the status bar color to white in UINavigationController.

If anyone want's to accomplish the same result by writing the code in AppDelegate then use below code and write it inside AppDelegate's didFinishLaunchingWithOptions method.

And don't forget to set the UIViewControllerBasedStatusBarAppearance to YES in the .plist file, else the change will not reflect.

Code

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
     // status bar appearance code
     [[UINavigationBar appearance] setBarStyle:UIBarStyleBlack];

     return YES;
}

I had same error and the mistake was that I had added list and dictionary into the same list (object) and when I used to iterate over the list of dictionaries and use to hit a list (type) object then I used to get this error.

Its was a code error and made sure that I only added dictionary objects to that list and list typed object into the list, this solved my issue as well.

Tilde ~ matches minor version, if you have installed a package that has 1.4.2 and after your installation, versions 1.4.3 and 1.4.4 are also available if in your package.json it is used as ~1.4.2 then npm install in your project after upgrade will install 1.4.4 in your project. But there is 1.5.0 available for that package then it will not be installed by ~. It is called minor version.

Caret ^ matches major version, if 1.4.2 package is installed in your project and after your installation 1.5.0 is released then ^ will install major version. It will not allow to install 2.1.0 if you have ^1.4.2.

Fixed version if you don't want to change version of package on each installation then used fixed version with out any special character e.g "1.4.2"

Latest Version * If you want to install latest version then only use * in front of package name.

I agree with Cade Roux.

This article should get you on the right track:

• Indexes in SQL Server 2005/2008 – Best Practices, Part 1
• Indexes in SQL Server 2005/2008 – Part 2 – Internals

One thing to note, clustered indexes should have a unique key (an identity column I would recommend) as the first column. Basically it helps your data insert at the end of the index and not cause lots of disk IO and Page splits.

Secondly, if you are creating other indexes on your data and they are constructed cleverly they will be reused.

e.g. imagine you search a table on three columns

state, county, zip.

• you sometimes search by state only.
• you sometimes search by state and county.
• you frequently search by state, county, zip.

Then an index with state, county, zip. will be used in all three of these searches.

If you search by zip alone quite a lot then the above index will not be used (by SQL Server anyway) as zip is the third part of that index and the query optimiser will not see that index as helpful.

You could then create an index on Zip alone that would be used in this instance.

By the way We can take advantage of the fact that with Multi-Column indexing the first index column is always usable for searching and when you search only by 'state' it is efficient but yet not as efficient as Single-Column index on 'state'

I guess the answer you are looking for is that it depends on your where clauses of your frequently used queries and also your group by's.

The article will help a lot. :-)

After a week of puzzling over this. I think I've figured it out.
I'm now using just an EditText inside of the Toolbar. This was suggested to me by oj88 on reddit.

I now have this:


First inside onCreate() of my activity I added the EditText with an image view on the right hand side to the Toolbar like this:

    // Setup search container view
    searchContainer = new LinearLayout(this);
    Toolbar.LayoutParams containerParams = new Toolbar.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
    containerParams.gravity = Gravity.CENTER_VERTICAL;
    searchContainer.setLayoutParams(containerParams);

    // Setup search view
    toolbarSearchView = new EditText(this);
    // Set width / height / gravity
    int[] textSizeAttr = new int[]{android.R.attr.actionBarSize};
    int indexOfAttrTextSize = 0;
    TypedArray a = obtainStyledAttributes(new TypedValue().data, textSizeAttr);
    int actionBarHeight = a.getDimensionPixelSize(indexOfAttrTextSize, -1);
    a.recycle();
    LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(0, actionBarHeight);
    params.gravity = Gravity.CENTER_VERTICAL;
    params.weight = 1;
    toolbarSearchView.setLayoutParams(params);

    // Setup display
    toolbarSearchView.setBackgroundColor(Color.TRANSPARENT);
    toolbarSearchView.setPadding(2, 0, 0, 0);
    toolbarSearchView.setTextColor(Color.WHITE);
    toolbarSearchView.setGravity(Gravity.CENTER_VERTICAL);
    toolbarSearchView.setSingleLine(true);
    toolbarSearchView.setImeActionLabel("Search", EditorInfo.IME_ACTION_UNSPECIFIED);
    toolbarSearchView.setHint("Search");
    toolbarSearchView.setHintTextColor(Color.parseColor("#b3ffffff"));
    try {
        // Set cursor colour to white
        // https://stackoverflow.com/a/26544231/1692770
        // https://github.com/android/platform_frameworks_base/blob/kitkat-release/core/java/android/widget/TextView.java#L562-564
        Field f = TextView.class.getDeclaredField("mCursorDrawableRes");
        f.setAccessible(true);
        f.set(toolbarSearchView, R.drawable.edittext_whitecursor);
    } catch (Exception ignored) {
    }

    // Search text changed listener
    toolbarSearchView.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {
        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            Fragment mainFragment = getFragmentManager().findFragmentById(R.id.container);
            if (mainFragment != null && mainFragment instanceof MainListFragment) {
                ((MainListFragment) mainFragment).search(s.toString());
            }
        }

        @Override
        public void afterTextChanged(Editable s) {
            // https://stackoverflow.com/a/6438918/1692770
            if (s.toString().length() <= 0) {
                toolbarSearchView.setHintTextColor(Color.parseColor("#b3ffffff"));
            }
        }
    });
    ((LinearLayout) searchContainer).addView(toolbarSearchView);

    // Setup the clear button
    searchClearButton = new ImageView(this);
    Resources r = getResources();
    int px = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 16, r.getDisplayMetrics());
    LinearLayout.LayoutParams clearParams = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
    clearParams.gravity = Gravity.CENTER;
    searchClearButton.setLayoutParams(clearParams);
    searchClearButton.setImageResource(R.drawable.ic_close_white_24dp); // TODO: Get this image from here: https://github.com/google/material-design-icons
    searchClearButton.setPadding(px, 0, px, 0);
    searchClearButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            toolbarSearchView.setText("");
        }
    });
    ((LinearLayout) searchContainer).addView(searchClearButton);

    // Add search view to toolbar and hide it
    searchContainer.setVisibility(View.GONE);
    toolbar.addView(searchContainer);

This worked, but then I came across an issue where onOptionsItemSelected() wasn't being called when I tapped on the home button. So I wasn't able to cancel the search by pressing the home button. I tried a few different ways of registering the click listener on the home button but they didn't work.

Eventually I found out that the ActionBarDrawerToggle I had was interfering with things, so I removed it. This listener then started working:

    toolbar.setNavigationOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // toolbarHomeButtonAnimating is a boolean that is initialized as false. It's used to stop the user pressing the home button while it is animating and breaking things.
            if (!toolbarHomeButtonAnimating) {
                // Here you'll want to check if you have a search query set, if you don't then hide the search box.
                // My main fragment handles this stuff, so I call its methods.
                FragmentManager fragmentManager = getFragmentManager();
                final Fragment fragment = fragmentManager.findFragmentById(R.id.container);
                if (fragment != null && fragment instanceof MainListFragment) {
                    if (((MainListFragment) fragment).hasSearchQuery() || searchContainer.getVisibility() == View.VISIBLE) {
                        displaySearchView(false);
                        return;
                    }
                }
            }

            if (mDrawerLayout.isDrawerOpen(findViewById(R.id.navigation_drawer)))
                mDrawerLayout.closeDrawer(findViewById(R.id.navigation_drawer));
            else
                mDrawerLayout.openDrawer(findViewById(R.id.navigation_drawer));
        }
    });

So I can now cancel the search with the home button, but I can't press the back button to cancel it yet. So I added this to onBackPressed():

    FragmentManager fragmentManager = getFragmentManager();
    final Fragment mainFragment = fragmentManager.findFragmentById(R.id.container);
    if (mainFragment != null && mainFragment instanceof MainListFragment) {
        if (((MainListFragment) mainFragment).hasSearchQuery() || searchContainer.getVisibility() == View.VISIBLE) {
            displaySearchView(false);
            return;
        }
    }

I created this method to toggle visibility of the EditText and menu item:

public void displaySearchView(boolean visible) {
    if (visible) {
        // Stops user from being able to open drawer while searching
        mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);

        // Hide search button, display EditText
        menu.findItem(R.id.action_search).setVisible(false);
        searchContainer.setVisibility(View.VISIBLE);

        // Animate the home icon to the back arrow
        toggleActionBarIcon(ActionDrawableState.ARROW, mDrawerToggle, true);

        // Shift focus to the search EditText
        toolbarSearchView.requestFocus();

        // Pop up the soft keyboard
        new Handler().postDelayed(new Runnable() {
            public void run() {
                toolbarSearchView.dispatchTouchEvent(MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_DOWN, 0, 0, 0));
                toolbarSearchView.dispatchTouchEvent(MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_UP, 0, 0, 0));
            }
        }, 200);
    } else {
        // Allows user to open drawer again
        mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);

        // Hide the EditText and put the search button back on the Toolbar.
        // This sometimes fails when it isn't postDelayed(), don't know why.
        toolbarSearchView.postDelayed(new Runnable() {
            @Override
            public void run() {
                toolbarSearchView.setText("");
                searchContainer.setVisibility(View.GONE);
                menu.findItem(R.id.action_search).setVisible(true);
            }
        }, 200);

        // Turn the home button back into a drawer icon
        toggleActionBarIcon(ActionDrawableState.BURGER, mDrawerToggle, true);

        // Hide the keyboard because the search box has been hidden
        InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(toolbarSearchView.getWindowToken(), 0);
    }
}

I needed a way to toggle the home button on the toolbar between the drawer icon and the back button. I eventually found the method below in this SO answer. Though I modified it slightly to made more sense to me:

private enum ActionDrawableState {
    BURGER, ARROW
}

/**
 * Modified version of this, https://stackoverflow.com/a/26836272/1692770<br>
 * I flipped the start offset around for the animations because it seemed like it was the wrong way around to me.<br>
 * I also added a listener to the animation so I can find out when the home button has finished rotating.
 */
private void toggleActionBarIcon(final ActionDrawableState state, final ActionBarDrawerToggle toggle, boolean animate) {
    if (animate) {
        float start = state == ActionDrawableState.BURGER ? 1.0f : 0f;
        float end = Math.abs(start - 1);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
            ValueAnimator offsetAnimator = ValueAnimator.ofFloat(start, end);
            offsetAnimator.setDuration(300);
            offsetAnimator.setInterpolator(new AccelerateDecelerateInterpolator());
            offsetAnimator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
                @Override
                public void onAnimationUpdate(ValueAnimator animation) {
                    float offset = (Float) animation.getAnimatedValue();
                    toggle.onDrawerSlide(null, offset);
                }
            });
            offsetAnimator.addListener(new Animator.AnimatorListener() {
                @Override
                public void onAnimationStart(Animator animation) {

                }

                @Override
                public void onAnimationEnd(Animator animation) {
                    toolbarHomeButtonAnimating = false;
                }

                @Override
                public void onAnimationCancel(Animator animation) {

                }

                @Override
                public void onAnimationRepeat(Animator animation) {

                }
            });
            toolbarHomeButtonAnimating = true;
            offsetAnimator.start();
        }
    } else {
        if (state == ActionDrawableState.BURGER) {
            toggle.onDrawerClosed(null);
        } else {
            toggle.onDrawerOpened(null);
        }
    }
}

This works, I've managed to work out a few bugs that I found along the way. I don't think it's 100% but it works well enough for me.

EDIT: If you want to add the search view in XML instead of Java do this:

toolbar.xml:

onCreate() of your Activity:

    searchContainer = findViewById(R.id.search_container);
    toolbarSearchView = (EditText) findViewById(R.id.search_view);
    searchClearButton = (ImageView) findViewById(R.id.search_clear);

    // Setup search container view
    try {
        // Set cursor colour to white
        // https://stackoverflow.com/a/26544231/1692770

        Field f = TextView.class.getDeclaredField("mCursorDrawableRes");
        f.setAccessible(true);
        f.set(toolbarSearchView, R.drawable.edittext_whitecursor);
    } catch (Exception ignored) {
    }

    // Search text changed listener
    toolbarSearchView.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {
        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            Fragment mainFragment = getFragmentManager().findFragmentById(R.id.container);
            if (mainFragment != null && mainFragment instanceof MainListFragment) {
                ((MainListFragment) mainFragment).search(s.toString());
            }
        }

        @Override
        public void afterTextChanged(Editable s) {
        }
    });

    // Clear search text when clear button is tapped
    searchClearButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

    searchContainer.setVisibility(View.GONE);

I had this due to one project referencing another.

1. Remove reference from project A to project B
2. Try running stuff, it will break
3. Re-add reference
4. Clean/Clean and build
5. Back in business

I was brought here for a reason not explicitly mentioned in the answers so far, so to save others the trouble:

The error also occurs if the function arguments have changed order - for the same reason as in the accepted answer: the positional arguments clash with the keyword arguments.

In my case it was because the argument order of the Pandas set_axis function changed between 0.20 and 0.22:

0.20: DataFrame.set_axis(axis, labels)
0.22: DataFrame.set_axis(labels, axis=0, inplace=None)

Using the commonly found examples for set_axis results in this confusing error, since when you call:

df.set_axis(['a', 'b', 'c'], axis=1)

prior to 0.22, ['a', 'b', 'c'] is assigned to axis because it's the first argument, and then the positional argument provides "multiple values".

You have to set both layout_gravity and layout_columntWeight on your columns

<android.support.v7.widget.GridLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <TextView android:text="??? ???"
        app:layout_gravity="fill_horizontal"
        app:layout_columnWeight="1"
        />

    <TextView android:text="??? ???"
        app:layout_gravity="fill_horizontal"
        app:layout_columnWeight="1"
        />

    <TextView android:text="??? ???"
        app:layout_gravity="fill_horizontal"
        app:layout_columnWeight="1"
        />
 </android.support.v7.widget.GridLayout>

just call your function inside the events.

load:

$(document).ready(function(){  // or  $(window).load(function(){
    topInViewport($(mydivname));
});

resize:

$(window).resize(function () {
    topInViewport($(mydivname));
});

scroll:

$(window).scroll(function () {
    topInViewport($(mydivname));
});

or bind all event in one function

$(window).on("load scroll resize",function(e){

For me, I added the nuget again and the problem was solved
