<div id="OK1"  runat="server" style ="display:none" >
    <asp:DropDownList ID="DropDownList2" runat="server"></asp:DropDownList>
</div>

vb.net code

  Protected Sub DropDownList1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles DropDownList1.SelectedIndexChanged
    If DropDownList1.SelectedIndex = 0 Then
        OK1.Style.Add("display", "none")
    Else
        OK1.Style.Add("display", "block")
    End If
End Sub

The best and clean way to do this is within the Item_Created Event :

 protected void rptSummary_ItemCreated(Object sender, RepeaterItemEventArgs e)
        {
            switch (e.Item.ItemType)
            {
                case ListItemType.AlternatingItem:
                    break;
                case ListItemType.EditItem:
                    break;
                case ListItemType.Footer:
                    e.Item.FindControl(ctrl);
                    break;
                case ListItemType.Header:
                    break;
                case ListItemType.Item:
                    break;
                case ListItemType.Pager:
                    break;
                case ListItemType.SelectedItem:
                    break;
                case ListItemType.Separator:
                    break;
                default:
                    break;
            }
    }

Make sure not to do something like this:

var a = $.cookie("cart").split(",");

Then, if the cookie doesn't exist, the debugger will return some unhelpful message like ".cookie not a function".

Always declare first, then do the split after checking for null. Like this:

var a = $.cookie("cart");
if (a != null) {
    var aa = a.split(",");

Because they are basically object oriented global variables, you can usually design your classes in such a way so that you don't need them.

There is a far easier solution (IMO) in Bootstrap 3 that does not require you to compile any custom LESS. You just have to leverage the cascade in "Cascading Style Sheets."

Set up your CSS loading like so...

<link type="text/css" rel="stylesheet" href="/css/bootstrap.css" />
<link type="text/css" rel="stylesheet" href="/css/custom.css" />

Where /css/custom.css is your unique style definitions. Inside that file, add the following definition...

@media (min-width: 1200px) {
  .container {
    width: 970px;
  }
}

This will override Bootstrap's default width: 1170px setting when the viewport is 1200px or bigger.

Tested in Bootstrap 3.0.2

These are all great solutions, However, if you are currently using Routing then I found this solution to be the easiest and least amount of code needed. Using the 'resolve' property to wait for a promise to complete before triggering the route. e.g.

$routeProvider
.when("/news", {
    templateUrl: "newsView.html",
    controller: "newsController",
    resolve: {
        message: function(messageService){
            return messageService.getMessage();
    }
}

})

Using collections.defaultdict is a big time-saver when you're building dicts and don't know beforehand which keys you're going to have.

Here it's used twice: for the resulting dict, and for each of the values in the dict.

import collections

def aggregate_names(errors):
    result = collections.defaultdict(lambda: collections.defaultdict(list))
    for real_name, false_name, location in errors:
        result[real_name][false_name].append(location)
    return result

Combining this with your code:

dictionary = aggregate_names(previousFunction(string))

Or to test:

EXAMPLES = [
    ('Fred', 'Frad', 123),
    ('Jim', 'Jam', 100),
    ('Fred', 'Frod', 200),
    ('Fred', 'Frad', 300)]
print aggregate_names(EXAMPLES)

I suspect you would just want to grab a few columns from V$SESSION and the SQL statement from V$SQL. Assuming you want to exclude the background processes that Oracle itself is running

SELECT sess.process, sess.status, sess.username, sess.schemaname, sql.sql_text
  FROM v$session sess,
       v$sql     sql
 WHERE sql.sql_id(+) = sess.sql_id
   AND sess.type     = 'USER'

The outer join is to handle those sessions that aren't currently active, assuming you want those. You could also get the sql_fulltext column from V$SQL which will have the full SQL statement rather than the first 1000 characters, but that is a CLOB and so likely a bit more complicated to deal with.

Realistically, you probably want to look at everything that is available in V$SESSION because it's likely that you can get a lot more information than SP_WHO provides.

I tend to use a variation of what mu is too short posted:

INSERT INTO something_log
SELECT NULL, s.*
FROM something AS s
WHERE s.id = 1;

As long as the tables have identical fields (excepting the auto increment on the log table), then this works nicely.

Since I use stored procedures whenever possible (to make life easier on other programmers who aren't too familiar with databases), this solves the problem of having to go back and update procedures every time you add a new field to a table.

It also ensures that if you add new fields to a table they will start appearing in the log table immediately without having to update your database queries (unless of course you have some that set a field explicitly)

Warning: You will want to make sure to add any new fields to both tables at the same time so that the field order stays the same... otherwise you will start getting odd bugs. If you are the only one that writes database interfaces AND you are very careful then this works nicely. Otherwise, stick to naming all of your fields.

Note: On second thought, unless you are working on a solo project that you are sure won't have others working on it stick to listing all field names explicitly and update your log statements as your schema changes. This shortcut probably is not worth the long term headache it can cause... especially on a production system.

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

In my sql use information function

select FOUND_ROWS();

it will return the no. of rows returned by select query.

My comment might not be relevant to the tags given. However, I was lead to this page from my search. I was looking for similar check in R and I came up the following with the help of @hugovdbeg post. I hope it would be helpful for someone who is looking for similar solution in R

JSON syntax is pretty much the JavaScript syntax for coding your object. Therefore, in terms of conciseness and speed, your own answer is the best bet.

I use this approach when populating dropdown lists in my KnockoutJS model. E.g.

var desktopGrpViewModel = {
    availableComputeOfferings: ko.observableArray(@Html.Raw(JsonConvert.SerializeObject(ViewBag.ComputeOfferings))),
    desktopGrpComputeOfferingSelected: ko.observable(),
};
ko.applyBindings(desktopGrpViewModel);

...

<select name="ComputeOffering" class="form-control valid" id="ComputeOffering" data-val="true" 
data-bind="options: availableComputeOffering,
           optionsText: 'Name',
           optionsValue: 'Id',
           value: desktopGrpComputeOfferingSelect,
           optionsCaption: 'Choose...'">
</select>

Note that I'm using Json.NET NuGet package for serialization and the ViewBag to pass data.

Replacing one string with another can be done in the below methods

Method 1: Using String replaceAll

 String myInput = "HelloBrother";
 String myOutput = myInput.replaceAll("HelloBrother", "Brother"); // Replace hellobrother with brother
 ---OR---
 String myOutput = myInput.replaceAll("Hello", ""); // Replace hello with empty
 System.out.println("My Output is : " +myOutput);       

Method 2: Using Pattern.compile

 import java.util.regex.Pattern;
 String myInput = "JAVAISBEST";
 String myOutputWithRegEX = Pattern.compile("JAVAISBEST").matcher(myInput).replaceAll("BEST");
 ---OR -----
 String myOutputWithRegEX = Pattern.compile("JAVAIS").matcher(myInput).replaceAll("");
 System.out.println("My Output is : " +myOutputWithRegEX);           

Method 3: Using Apache Commons as defined in the link below:

http://commons.apache.org/proper/commons-lang/javadocs/api-z.1/org/apache/commons/lang3/StringUtils.html#replace(java.lang.String, java.lang.String, java.lang.String)

REFERENCE

Best I found on internet for this is ngx-navigation-with-data. It is very simple and good for navigation the data from one component to another component. You have to just import the component class and use it in very simple way. Suppose you have home and about component and want to send data then

HOME COMPONENT

import { Component, OnInit } from '@angular/core';
import { NgxNavigationWithDataComponent } from 'ngx-navigation-with-data';

@Component({
 selector: 'app-home',
 templateUrl: './home.component.html',
 styleUrls: ['./home.component.css']
})
export class HomeComponent implements OnInit {

constructor(public navCtrl: NgxNavigationWithDataComponent) { }

 ngOnInit() {
 }

 navigateToABout() {
  this.navCtrl.navigate('about', {name:"virendta"});
 }

}

ABOUT COMPONENT

import { Component, OnInit } from '@angular/core';
import { NgxNavigationWithDataComponent } from 'ngx-navigation-with-data';

@Component({
 selector: 'app-about',
 templateUrl: './about.component.html',
 styleUrls: ['./about.component.css']
})
export class AboutComponent implements OnInit {

 constructor(public navCtrl: NgxNavigationWithDataComponent) {
  console.log(this.navCtrl.get('name')); // it will console Virendra
  console.log(this.navCtrl.data); // it will console whole data object here
 }

 ngOnInit() {
 }

}

Give a try to .bringToFront():

http://developer.android.com/reference/android/view/View.html#bringToFront%28%29

I managed to do something similar by using this URL:

http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.industry%20where%20id%20in%20(select%20industry.id%20from%20yahoo.finance.sectors)&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys

It downloads a complete list of stock symbols using the Yahoo YQL API, including the stock name, stock symbol, and industry ID. What it doesn't seem to have is any sort of stock symbol modifiers. E.g. for Rogers Communications Inc, it only downloads RCI, not RCI-A.TO, RCI-B.TO, etc. I haven't found a source for that information yet - if anyone knows of a way to automate downloading that, I'd like to hear it. Also, it'd be nice to find a way to download some sort of relation between the stock symbol and the exchange it's traded on, since some are traded on multiple exchanges, or maybe I only want to look at stuff on the TSX or something.

if you are using visual studio , enable the build property "Prefer 32-bit". see image below.

And if you came here looking for slicing two ranges of columns and combining them together (like me) you can do something like

op = df[list(df.columns[0:899]) + list(df.columns[3593:])]
print op

This will create a new dataframe with first 900 columns and (all) columns > 3593 (assuming you have some 4000 columns in your data set).

Use a JSON parser, like JSON.NET

string json = "{ \"Atlantic/Canary\": \"GMT Standard Time\", \"Europe/Lisbon\": \"GMT Standard Time\", \"Antarctica/Mawson\": \"West Asia Standard Time\", \"Etc/GMT+3\": \"SA Eastern Standard Time\", \"Etc/GMT+2\": \"UTC-02\", \"Etc/GMT+1\": \"Cape Verde Standard Time\", \"Etc/GMT+7\": \"US Mountain Standard Time\", \"Etc/GMT+6\": \"Central America Standard Time\", \"Etc/GMT+5\": \"SA Pacific Standard Time\", \"Etc/GMT+4\": \"SA Western Standard Time\", \"Pacific/Wallis\": \"UTC+12\", \"Europe/Skopje\": \"Central European Standard Time\", \"America/Coral_Harbour\": \"SA Pacific Standard Time\", \"Asia/Dhaka\": \"Bangladesh Standard Time\", \"America/St_Lucia\": \"SA Western Standard Time\", \"Asia/Kashgar\": \"China Standard Time\", \"America/Phoenix\": \"US Mountain Standard Time\", \"Asia/Kuwait\": \"Arab Standard Time\" }";
var data = (JObject)JsonConvert.DeserializeObject(json);
string timeZone = data["Atlantic/Canary"].Value<string>();

You can also name columns directly in the cbind call, e.g.

cbind(date=c(0,1), high=c(2,3))

Output:

     date high
[1,]    0    2
[2,]    1    3

    }
    fragmentTransaction.addToBackStack(null);

    MyDialog dialog = new MyDialog();
    dialog.show(fragmentTransaction, MyDialog.class.getName());
}

In SQL Server 2016 (13.x) and above

DROP TABLE IF EXISTS dbo.Scores

In earlier versions

IF OBJECT_ID('dbo.Scores', 'U') IS NOT NULL 
DROP TABLE dbo.Scores; 

U is your table type

Break down the algorithm into pieces you know the big O notation for, and combine through big O operators. That's the only way I know of.

For more information, check the Wikipedia page on the subject.

it would be helpful to know if you use linux or windows. in linux the settings are located in ~/.smartgit/3. You could try to remove this folder. Imho this is also worth a try in Windows.

.size() is not a native JS function of Array (at least not in any browser that I know of).

.length should be used.

If

.size() does work on your page, make sure you do not have any extra libraries included like prototype that is mucking with the Array prototype.

or

There might be some plugin on your browser that is mucking with the Array prototype.

Group Join method is unnecessary to achieve joining of two data sets.

Inner Join:

var qry = Foos.SelectMany
            (
                foo => Bars.Where (bar => foo.Foo_id == bar.Foo_id),
                (foo, bar) => new
                    {
                    Foo = foo,
                    Bar = bar
                    }
            );

For Left Join just add DefaultIfEmpty()

var qry = Foos.SelectMany
            (
                foo => Bars.Where (bar => foo.Foo_id == bar.Foo_id).DefaultIfEmpty(),
                (foo, bar) => new
                    {
                    Foo = foo,
                    Bar = bar
                    }
            );

EF and LINQ to SQL correctly transform to SQL. For LINQ to Objects it is beter to join using GroupJoin as it internally uses Lookup. But if you are querying DB then skipping of GroupJoin is AFAIK as performant.

Personlay for me this way is more readable compared to GroupJoin().SelectMany()

Tomcat is a web server (can handle HTTP requests/responses) and web container (implements Java Servlet API, also called servletcontainer) in one. Some may call it an application server, but it is definitely not an fullfledged Java EE application server (it does not implement the whole Java EE API).

See also:

• What exactly is Java EE?
• How do servlets work? Instantiation, sessions, shared variables and multithreading

for (int i = 0; i < list.length; i++) {
   if (list.get(i) .getName().equalsIgnoreCase("myName")) {
    System.out.println(i);
    break;
  }
}

Your distribution should provide a utility called pdftotext:

find /path -name '*.pdf' -exec sh -c 'pdftotext "{}" - | grep --with-filename --label="{}" --color "your pattern"' \;

The "-" is necessary to have pdftotext output to stdout, not to files. The --with-filename and --label= options will put the file name in the output of grep. The optional --color flag is nice and tells grep to output using colors on the terminal.

(In Ubuntu, pdftotext is provided by the package xpdf-utils or poppler-utils.)

This method, using pdftotext and grep, has an advantage over pdfgrep if you want to use features of GNU grep that pdfgrep doesn't support. Note: pdfgrep-1.3.x supports -C option for printing line of context.

You can use System.arraycopy().

int[] source = new int[1000];

int[] part1 = new int[500];
int[] part2 = new int[500];

//              (src   , src-offset  , dest , offset, count)
System.arraycopy(source, 0           , part1, 0     , part1.length);
System.arraycopy(source, part1.length, part2, 0     , part2.length);

Since many browsers block popups by default and popups are really ugly, I recommend using lightbox or thickbox.

They are prettier and are not popups. They are extra HTML markups that are appended to your document's body with the appropriate CSS content.

NOTE: Hopefully this changed in the latest version.

You cannot copy data between a MongoDB 4.0 mongod instance (regardless of the FCV value) and a MongoDB 3.4 and earlier mongod instance. https://docs.mongodb.com/v4.0/reference/method/db.copyDatabase/

ALERT: Hey folks just be careful while copying the database, if you don't want to mess up the different collections under single database.

The following shows you how to rename

> show dbs;
testing
games
movies

To rename you use the following syntax

db.copyDatabase("old db name","new db name")

Example:

db.copyDatabase('testing','newTesting')

Now you can safely delete the old db by the following way

use testing;

db.dropDatabase(); //Here the db **testing** is deleted successfully

Now just think what happens if you try renaming the new database name with existing database name

Example:

db.copyDatabase('testing','movies'); 

So in this context all the collections (tables) of testing will be copied to movies database.

To update existing remote to track specific branches only use:

git remote set-branches <remote-name> <branch-name>

From git help remote:

set-branches
    Changes the list of branches tracked by the named remote. This can be used to track a subset of the available remote branches
    after the initial setup for a remote.

    The named branches will be interpreted as if specified with the -t option on the git remote add command line.

    With --add, instead of replacing the list of currently tracked branches, adds to that list.

My best guess is that this is not a bug, but a feature of Sql 2012. ;-) In other contexts, you'd be happy to retain your cr-lf's, like when copying a big chunk of text. It's just that it doesn't work well in your situation.

You could always strip them out in your select. This would make your query for as you intend in both versions:

select REPLACE(col, CHAR(13) + CHAR(10), ', ') from table

A more generic approach

To simplify this approach an "id" interface is used

public interface IGuidKey
{
    Guid Id { get; set; }
}

The helper method

public static void Modify<T>(this DbSet<T> set, Guid id, Action<T> func)
    where T : class, IGuidKey, new()
{
    var target = new T
    {
        Id = id
    };
    var entry = set.Attach(target);
    func(target);
    foreach (var property in entry.Properties)
    {
        var original = property.OriginalValue;
        var current = property.CurrentValue;

        if (ReferenceEquals(original, current))
        {
            continue;
        }

        if (original == null)
        {
            property.IsModified = true;
            continue;
        }

        var propertyIsModified = !original.Equals(current);
        property.IsModified = propertyIsModified;
    }
}

Usage

dbContext.Operations.Modify(id, x => { x.Title = "aaa"; });

Sometimes you get the error because the destination location in phone are not exist. For example, some android phone external storage location is /storage/emulated/legacy instead of /storage/emulated/0.

I just spend an hour on this, I'm new to Oracle so i was thoroughly confused..

the situation:

just installed visual studio 2012 Oracle developer tools. When i did this I lost the items in my drop down which contained my TNS entries in TOAD. I was getting this error from Visual studio AND TOAD!! WTH! so i added the environmental Variable TNS_ADMIN under "ALL USERS" with the path to my .ora file (which i now worked fine because it worked until I broke it). Toad picked up that change. Still Visual Studio wouldn't give me any love... still getting same error. THEN, i added the environmental Variable TO MY USER VARIABLES.. VIOLA!!

ENSURE THE ENVIRONMENTAL VARIABLES ARE SET FOR THE SYSTEM AND THE USER

It works with me only if I set the footer/header of the tableview to nil first:

self.footer = self.searchTableView.tableFooterView;
CGRect frame = self.footer.frame;
frame.size.height = 200;
self.footer.frame = frame;
self.searchTableView.tableFooterView = nil;
self.searchTableView.tableFooterView = self.footer;

Make sure that self.footer is a strong reference to prevent the footer view from being deallocated

Use the CSS property list-style-position to position the bullet:

list-style-position:inside /* or outside */;

Use the getResourceAsStream() method on the ServletContext object, e.g.

servletContext.getResourceAsStream("/WEB-INF/myfile");

How you get a reference to the ServletContext depends on your application... do you want to do it from a Servlet or from a JSP?

EDITED: If you're inside a Servlet object, then call getServletContext(). If you're in JSP, use the predefined variable application.

Avoid any? for large arrays.

• any? is O(n)
• empty? is O(1)

any? does not check the length but actually scans the whole array for truthy elements.

static VALUE
rb_ary_any_p(VALUE ary)
{
  long i, len = RARRAY_LEN(ary);
  const VALUE *ptr = RARRAY_CONST_PTR(ary);

  if (!len) return Qfalse;
  if (!rb_block_given_p()) {
    for (i = 0; i < len; ++i) if (RTEST(ptr[i])) return Qtrue;
  }
  else {
    for (i = 0; i < RARRAY_LEN(ary); ++i) {
        if (RTEST(rb_yield(RARRAY_AREF(ary, i)))) return Qtrue;
    }
  }
  return Qfalse;
}

empty? on the other hand checks the length of the array only.

static VALUE
rb_ary_empty_p(VALUE ary)
{
  if (RARRAY_LEN(ary) == 0)
    return Qtrue;
  return Qfalse;
}

The difference is relevant if you have "sparse" arrays that start with lots of nil values, like for example an array that was just created.

Pass float to sleep, like sleep 0.1

If you bind your service, you will get the Extra in onBind(Intent intent).

Activity:

 Intent intent = new Intent(this, LocationService.class);                                                                                     
 intent.putExtra("tour_name", mTourName);                    
 bindService(intent, mServiceConnection, BIND_AUTO_CREATE); 

Service:

@Override
public IBinder onBind(Intent intent) {
    mTourName = intent.getStringExtra("tour_name");
    return mBinder;
}

Ctrl + Alt + L works with Android Studio under xfce4 on Linux. I see that Gnome used to use this shortcut for lock screen, but in Gnome 3 it was changed to Super+L (AKA Windows+L): https://wiki.gnome.org/Design/OS/KeyboardShortcuts

Url.Action() will get you the bare URL for most overloads of Html.ActionLink, but I think that the URL-from-lambda functionality is only available through Html.ActionLink so far. Hopefully they'll add a similar overload to Url.Action at some point.

It seems to me to be a bug in PHP. The error

'Fatal error: Uncaught Error: Using $this when not in object context in'

appears in the function using $this, but the error is that the calling function is using non-static function as a static. I.e:

Class_Name
{
    function foo()
    {
        $this->do_something(); // The error appears there.
    }
    function do_something()
    {
        ///
    }
}

While the error is here:

Class_Name::foo();

I used the below code and it worked for me:

@InjectMocks
private ClassABC classABC;

@Before
public void setUp() {
    ReflectionTestUtils.setField(classABC, "constantFromConfigFile", 3);
}

It might be helpful to address this question from a package deployment perspective.

There are many tutorials out there that explain how to publish a package to PyPi. Below are a couple I have used;

medium
real python

My experience is that most of these tutorials only have you use the .tar of the source, not a wheel. Thus, when installing packages created using these tutorials, I've received the "Failed to build wheel" error.

I later found the link on PyPi to the Python Software Foundation's docs PSF Docs. I discovered that their setup and build process is slightly different, and does indeed included building a wheel file.

After using the officially documented method, I no longer received the error when installing my packages.

So, the error might simply be a matter of how the developer packaged and deployed the project. None of us were born knowing how to use PyPi, and if they happened upon the wrong tutorial -- well, you can fill in the blanks.

I'm sure that is not the only reason for the error, but I'm willing to bet that is a major reason for it.

If your intention is to get hold of already instantiated controller of another component and that if you are following component/directive based approach you can always require a controller (instance of a component) from a another component that follows a certain hierarchy.

For example:

//some container component that provides a wizard and transcludes the page components displayed in a wizard
myModule.component('wizardContainer', {
  ...,
  controller : function WizardController() {
    this.disableNext = function() { 
      //disable next step... some implementation to disable the next button hosted by the wizard
    }
  },
  ...
});

//some child component
myModule.component('onboardingStep', {
 ...,
 controller : function OnboadingStepController(){

    this.$onInit = function() {
      //.... you can access this.container.disableNext() function
    }

    this.onChange = function(val) {
      //..say some value has been changed and it is not valid i do not want wizard to enable next button so i call container's disable method i.e
      if(notIsValid(val)){
        this.container.disableNext();
      }
    }
 },
 ...,
 require : {
    container: '^^wizardContainer' //Require a wizard component's controller which exist in its parent hierarchy.
 },
 ...
});

Now the usage of these above components might be something like this:

<wizard-container ....>
<!--some stuff-->
...
<!-- some where there is this page that displays initial step via child component -->

<on-boarding-step ...>
 <!--- some stuff-->
</on-boarding-step>
...
<!--some stuff-->
</wizard-container>

There are many ways you can set up require.

(no prefix) - Locate the required controller on the current element. Throw an error if not found.

? - Attempt to locate the required controller or pass null to the link fn if not found.

^ - Locate the required controller by searching the element and its parents. Throw an error if not found.

^^ - Locate the required controller by searching the element's parents. Throw an error if not found.

?^ - Attempt to locate the required controller by searching the element and its parents or pass null to the link fn if not found.

Old Answer:

You need to inject $controller service to instantiate a controller inside another controller. But be aware that this might lead to some design issues. You could always create reusable services that follows Single Responsibility and inject them in the controllers as you need.

Example:

app.controller('TestCtrl2', ['$scope', '$controller', function ($scope, $controller) {
   var testCtrl1ViewModel = $scope.$new(); //You need to supply a scope while instantiating.
   //Provide the scope, you can also do $scope.$new(true) in order to create an isolated scope.
   //In this case it is the child scope of this scope.
   $controller('TestCtrl1',{$scope : testCtrl1ViewModel });
   testCtrl1ViewModel.myMethod(); //And call the method on the newScope.
}]);

In any case you cannot call TestCtrl1.myMethod() because you have attached the method on the $scope and not on the controller instance.

If you are sharing the controller, then it would always be better to do:-

.controller('TestCtrl1', ['$log', function ($log) {
    this.myMethod = function () {
        $log.debug("TestCtrl1 - myMethod");
    }
}]);

and while consuming do:

.controller('TestCtrl2', ['$scope', '$controller', function ($scope, $controller) {
     var testCtrl1ViewModel = $controller('TestCtrl1');
     testCtrl1ViewModel.myMethod();
}]);

In the first case really the $scope is your view model, and in the second case it the controller instance itself.

There are several ways to write output from a Visual Studio unit test in C#:

• Console.Write - The Visual Studio test harness will capture this and show it when you select the test in the Test Explorer and click the Output link. Does not show up in the Visual Studio Output Window when either running or debugging a unit test (arguably this is a bug).
• Debug.Write - The Visual Studio test harness will capture this and show it in the test output. Does appear in the Visual Studio Output Window when debugging a unit test, unless Visual Studio Debugging options are configured to redirect Output to the Immediate Window. Nothing will appear in the Output (or Immediate) Window if you simply run the test without debugging. By default only available in a Debug build (that is, when DEBUG constant is defined).
• Trace.Write - The Visual Studio test harness will capture this and show it in the test output. Does appear in the Visual Studio Output (or Immediate) Window when debugging a unit test (but not when simply running the test without debugging). By default available in both Debug and Release builds (that is, when TRACE constant is defined).

Confirmed in Visual Studio 2013 Professional.

select t.username, t.date, t.value
from MyTable t

Reason for this error is that PHP does not have a list of trusted certificate authorities.

PHP 5.6 and later try to load the CAs trusted by the system automatically. Issues with that can be fixed. See http://php.net/manual/en/migration56.openssl.php for more information.

PHP 5.5 and earlier are really hard to setup correctly since you manually have to specify the CA bundle in each request context, a thing you do not want to sprinkle around your code. So I decided for my code that for PHP versions < 5.6, SSL verification simply gets disabled:

$req = new HTTP_Request2($url);
if (version_compare(PHP_VERSION, '5.6.0', '<')) {
    //correct ssl validation on php 5.5 is a pain, so disable
    $req->setConfig('ssl_verify_host', false);
    $req->setConfig('ssl_verify_peer', false);
}

Definitely should use a dict using the "group" + str(i) key as described in the accepted solution but I wanted to share a solution using exec. Its a way to parse strings into commands & execute them dynamically. It would allow to create these scalar variable names as per your requirement instead of using a dict. This might help in regards what not to do, and just because you can doesn't mean you should. Its a good solution only if using scalar variables is a hard requirement:

l = locals()
for i in xrange(3):
    exec("group" + str(i) + "= self.getGroup(selected, header + i)")

Another example where this could work using a Django model example. The exec alternative solution is commented out and the better way of handling such a case using the dict attribute makes more sense:

Class A(models.Model):

    ....

    def __getitem__(self, item):  # a.__getitem__('id')
        #exec("attrb = self." + item)
        #return attrb
        return self.__dict__[item]

It might make more sense to extend from a dictionary in the first place to get setattr and getattr functions.

A situation which involves parsing, for example generating & executing python commands dynamically, exec is what you want :) More on exec here.

You use the id property to the get the id, then the substr method to remove the first part of it, then optionally parseInt to turn it into a number:

var id = theElement.id.substr(5);

or:

var id = parseInt(theElement.id.substr(5));

Httponly cookies' purpose is being inaccessible by script, so you CAN NOT.

just use echo'd javascript to rid the URL of any variables with a self-submitting, blank form:

    <?
    if (isset($_GET['your_var'])){
    //blah blah blah code
    echo "<script type='text/javascript'>unsetter();</script>"; 
    ?> 

Then make this javascript function:

    function unsetter() {
    $('<form id = "unset" name = "unset" METHOD="GET"><input type="submit"></form>').appendTo('body');
    $( "#unset" ).submit();
    }

Queue is an Interface so you can not initiate it directly. Initiate it by one of its implementing classes.

From the docs all known implementing classes:

• AbstractQueue
• ArrayBlockingQueue
• ArrayDeque
• ConcurrentLinkedQueue
• DelayQueue
• LinkedBlockingDeque
• LinkedBlockingQueue
• LinkedList
• PriorityBlockingQueue
• PriorityQueue
• SynchronousQueue

You can use any of above based on your requirement to initiate a Queue object.

As per the HTML:

<html>
    <body>
    <p class="content">Link1.</p>
    </body>
<html>
<html>
    <body>
    <p class="content">Link2.</p>
    </body>
<html>

Two(2) <p> elements are having the same class content.

So to filter the elements having the same class i.e. content and create a list you can use either of the following Locator Strategies:

• Using class_name:

  elements = driver.find_elements_by_class_name("content")
  

• Using css_selector:

   elements = driver.find_elements_by_css_selector(".content")
  

• Using xpath:

  elements = driver.find_elements_by_xpath("//*[@class='content']")
  

Ideally, to click on the element you need to induce WebDriverWait for the visibility_of_all_elements_located() and you can use either of the following Locator Strategies:

• Using CLASS_NAME:

  elements = WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CLASS_NAME, "content")))
  

• Using CSS_SELECTOR:

  elements = WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, ".content")))
  

• Using XPATH:

  elements = WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//*[@class='content']")))
  

• Note : You have to add the following imports :

  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support import expected_conditions as EC

how about complex types? when array contains objects... or any else

My variant:

Object.prototype.copy = function(){
    var v_newObj = {};
    for(v_i in this)
        v_newObj[v_i] = (typeof this[v_i]).contains(/^(array|object)$/) ? this[v_i].copy() : this[v_i];
    return v_newObj;
}

Array.prototype.copy = function(){
    var v_newArr = [];
    this.each(function(v_i){
        v_newArr.push((typeof v_i).contains(/^(array|object)$/) ? v_i.copy() : v_i);
    });
    return v_newArr;
}

It's not final version, just an idea.

PS: method each and contains are prototypes also.

Great question.

Consider the following example (scroller is a UIScrollView):

float offset = 1000;
[super viewDidLoad];
for (int i=0;i<500; i++) {
    UILabel *label = [[[UILabel alloc] initWithFrame:CGRectMake(i * 100, 50, 95, 100)] autorelease];
    [label setText:[NSString stringWithFormat:@"label %d",i]];
    [self.scroller addSubview:label];
    [self.scroller setContentSize:CGSizeMake(self.view.frame.size.width * 2 + offset, 0)];
    [self.scroller setContentInset:UIEdgeInsetsMake(0, -offset, 0, 0)];
}

The insets are the ONLY way to force your scroller to have a "window" on the content where you want it. I'm still messing with this sample code, but the idea is there: use the insets to get a "window" on your UIScrollView.

This should give you a start

    some_function(arr[:,col])

Your example as written works perfectly in Chrome 11 for me. Perhaps your browser just doesn't support the :not() selector?

You may need to use JavaScript or similar to accomplish this cross-browser. jQuery implements :not() in its selector API.

If you purpose it to a html input, you can easily do this without the use of JavaScript! or any other JS libraries. It would be standard and very easy to use a CSS tag text-transform:

<input type="text" style="text-transform: uppercase" >

or you can use a bootstrap class named as "text-uppercase"

<input type="text" class="text-uppercase" >

In this manner, your code is much simpler!

You can provide padding to an input like this:

HTML:

<input type=text id=firstname />

CSS:

input {
    width: 250px;
    padding: 5px;
}

however I would also add:

input {
    width: 250px;
    padding: 5px;
    -webkit-box-sizing: border-box; /* Safari/Chrome, other WebKit */
    -moz-box-sizing: border-box;    /* Firefox, other Gecko */
    box-sizing: border-box;         /* Opera/IE 8+ */
}

Box sizing makes the input width stay at 250px rather than increase to 260px due to the padding.

For reference.

You could just use a margin-left with a percentage.

HTML

<div class="goleft">Left Div</div>
<div class="goright">Right Div</div>

CSS

.goright{
    margin-left:20%;
}
.goleft{
    margin-right:20%;
}

(goleft would be the same as default, but can reverse if needed)

text-align doesn't always work as intended for layout options, it's mainly just for text. (But is often used for form elements too).

The end result of doing this will have a similar effect to a div with float:right; and width:80% set. Except, it won't clump together like a float will. (Saving the default display properties for the elements that come after).

Despite onclick Method you can also use formaction as follows:

<button type="submit" id="button1" name="button1" formaction='@Url.Action("Action", "Controller")'>Save</button>

Big O is the upper bound, while Omega is the lower bound. Theta requires both Big O and Omega, so that's why it's referred to as a tight bound (it must be both the upper and lower bound).

For example, an algorithm taking Omega(n log n) takes at least n log n time, but has no upper limit. An algorithm taking Theta(n log n) is far preferential since it takes at least n log n (Omega n log n) and no more than n log n (Big O n log n).

Is the memory space consumed by one object with 100 attributes the same as that of 100 objects, with one attribute each?

No.

How much memory is allocated for an object?

• The overhead is 8 bytes on 32-bit, 12 bytes on 64-bit; and then rounded up to a multiple of 4 bytes (32-bit) or 8 bytes (64-bit).

How much additional space is used when adding an attribute?

• Attributes range from 1 byte (byte) to 8 bytes (long/double), but references are either 4 bytes or 8 bytes depending not on whether it's 32bit or 64bit, but rather whether -Xmx is < 32Gb or >= 32Gb: typical 64-bit JVM's have an optimisation called "-UseCompressedOops" which compress references to 4 bytes if the heap is below 32Gb.

I had the same problem. Please try this:

Sub deleteConn(xlBook)
    For Each Cn In xlBook.Connections
        Cn.Delete
    Next Cn

    For Each xlsheet In xlBook.Worksheets
        For Each Qt In xlsheet.QueryTables

• Add LastItemMargin property to MarginSetter to specially handle the last item
• Add Spacing attached property with Vertical and Horizontal properties that adds spacing between items in vertical and horizontal lists and eliminates any trailing margin at the end of the list

Example:

<StackPanel Orientation="Horizontal" foo:Spacing.Horizontal="5">
  <Button>Button 1</Button>
  <Button>Button 2</Button>
</StackPanel>

<StackPanel Orientation="Vertical" foo:Spacing.Vertical="5">
  <Button>Button 1</Button>
  <Button>Button 2</Button>
</StackPanel>

<!-- Same as vertical example above -->

Use a trap!

tempfiles=( )
cleanup() {
  rm -f "${tempfiles[@]}"
}
trap cleanup 0

error() {
  local parent_lineno="$1"
  local message="$2"
  local code="${3:-1}"
  if [[ -n "$message" ]] ; then
    echo "Error on or near line ${parent_lineno}: ${message}; exiting with status ${code}"
  else
    echo "Error on or near line ${parent_lineno}; exiting with status ${code}"
  fi
  exit "${code}"
}
trap 'error ${LINENO}' ERR

...then, whenever you create a temporary file:

temp_foo="$(mktemp -t foobar.XXXXXX)"
tempfiles+=( "$temp_foo" )

and $temp_foo will be deleted on exit, and the current line number will be printed. (set -e will likewise give you exit-on-error behavior, though it comes with serious caveats and weakens code's predictability and portability).

You can either let the trap call error for you (in which case it uses the default exit code of 1 and no message) or call it yourself and provide explicit values; for instance:

error ${LINENO} "the foobar failed" 2

will exit with status 2, and give an explicit message.

you can always use iteration param:

ITER=0
for I in ${FOO[@]}
do  
    echo ${I} ${ITER}
    ITER=$(expr $ITER + 1)
done

Just to add to the responses above. I had this same issue when i first started using ASP.Net MVC and i was doing a Response.Redirect during a controller action:

Response.Redirect("/blah", true);

Instead of returning a Response.Redirect action i should have been returning a RedirectAction:

return Redirect("/blah");

Based on this answer: https://stackoverflow.com/a/5916874/1060344, here is another way I figured out which I use in one of my projects. For whatever you replace sys.stderr or sys.stdout with, you have to make sure that the replacement complies with file interface, especially if this is something you are doing because stderr/stdout are used in some other library that is not under your control. That library may be using other methods of file object.

Check out this way where I still let everything go do stderr/stdout (or any file for that matter) and also send the message to a log file using Python's logging facility (but you can really do anything with this):

class FileToLogInterface(file):
    '''
    Interface to make sure that everytime anything is written to stderr, it is
    also forwarded to a file.
    '''

    def __init__(self, *args, **kwargs):
        if 'cfg' not in kwargs:
            raise TypeError('argument cfg is required.')
        else:
            if not isinstance(kwargs['cfg'], config.Config):
                raise TypeError(
                    'argument cfg should be a valid '
                    'PostSegmentation configuration object i.e. '
                    'postsegmentation.config.Config')
        self._cfg = kwargs['cfg']
        kwargs.pop('cfg')

        self._logger = logging.getlogger('access_log')

        super(FileToLogInterface, self).__init__(*args, **kwargs)

    def write(self, msg):
        super(FileToLogInterface, self).write(msg)
        self._logger.info(msg)

Why do you want to do that?

However, You can do this:

public void foo(int param1)
{
    int param2 = 2;
    // rest of code
}

or:

public void foo(int param1, int param2)
{
    // rest of code
}

public void foo(int param1)
{
    foo(param1, 2);
}

    var pass2 = document.getElementById("pass2").value;
    var ok = true;
    if (pass1 != pass2) {

In Python, "privacy" depends on "consenting adults'" levels of agreement - you can't force it (any more than you can in real life;-). A single leading underscore means you're not supposed to access it "from the outside" -- two leading underscores (w/o trailing underscores) carry the message even more forcefully... but, in the end, it still depends on social convention and consensus: Python's introspection is forceful enough that you can't handcuff every other programmer in the world to respect your wishes.

((Btw, though it's a closely held secret, much the same holds for C++: with most compilers, a simple #define private public line before #includeing your .h file is all it takes for wily coders to make hash of your "privacy"...!-))

Another alternative...

According to the HTML5 CR, which requires continued support to “obsolete” features, too, the align=center attribute is rather tricky. Rendering rules for tables say: td elements with that attribute “are expected to center text within themselves, as if they had their 'text-align' property set to 'center' in a presentational hint, and to align descendants to the center.”

And aligning descendants is defined as so that a browser will “align only those descendants that have both their 'margin-left' and 'margin-right' properties computing to a value other than 'auto', that are over-constrained and that have one of those two margins with a used value forced to a greater value, and that do not themselves have an applicable align attribute. When multiple elements are to align a particular descendant, the most deeply nested such element is expected to override the others. Aligned elements are expected to be aligned by having the used values of their left and right margins be set accordingly.”

So it really depends on the content.

Each cell in the array is treated as unsigned int:

private int unsignedIntFromByteArray(byte[] bytes) {
int res = 0;
if (bytes == null)
    return res;


for (int i=0;i<bytes.length;i++){
    res = res | ((bytes[i] & 0xff) << i*8);
}
return res;
}

Sheets("your sheetname").range("A5:X50").Value = ""

You can also use

ActiveSheet.range

This is not a generic solution, however, if your pupose is to have or maintain email templates then System.Web has a built-in class called MailDefinition. This class is used by the ASP.NET membership controls to create HTML emails.

Does the same kind of 'string replace' things as mentioned above, but packs it all into a MailMessage for you.

Here is an example from MSDN:

ListDictionary replacements = new ListDictionary();
replacements.Add("<%To%>",sourceTo.Text);
replacements.Add("<%From%>", md.From);
System.Net.Mail.MailMessage fileMsg;
fileMsg = md.CreateMailMessage(toAddresses, replacements, emailTemplate, this); 
return fileMsg;

For UTC:

string unixTimestamp = Convert.ToString((int)DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1)).TotalSeconds);

For local system:

string unixTimestamp = Convert.ToString((int)DateTime.Now.Subtract(new DateTime(1970, 1, 1)).TotalSeconds);

Vertical tab was used to speed up printer vertical movement. Some printers used special tab belts with various tab spots. This helped align content on forms. VT to header space, fill in header, VT to body area, fill in lines, VT to form footer. Generally it was coded in the program as a character constant. From the keyboard, it would be CTRL-K.

I don't believe anyone would have a reason to use it any more. Most forms are generated in a printer control language like postscript.

@Talvi Wilson noted it used in python '\v'.

print("hello\vworld")

Output:

hello
     world

The above output appears to result in the default vertical size being one line. I have tested with perl "\013" and the same output occurs. This could be used to do line feed without a carriage return on devices with convert linefeed to carriage-return + linefeed.

Often you want to pass a viewmodel also, and not the only one file. In the code below you'll find some other useful features:

• checking if the file has been attached
• checking if file size is 0
• checking if file size is above 4 MB
• checking if file size is less than 100 bytes
• checking file extensions

It could be done via the following code:

[HttpPost]
public ActionResult Index(MyViewModel viewModel)
{
    // if file's content length is zero or no files submitted

    if (Request.Files.Count != 1 || Request.Files[0].ContentLength == 0)
    {
        ModelState.AddModelError("uploadError", "File's length is zero, or no files found");
        return View(viewModel);
    }

    // check the file size (max 4 Mb)

    if (Request.Files[0].ContentLength > 1024 * 1024 * 4)
    {
        ModelState.AddModelError("uploadError", "File size can't exceed 4 MB");
        return View(viewModel);
    }

    // check the file size (min 100 bytes)

    if (Request.Files[0].ContentLength < 100)
    {
        ModelState.AddModelError("uploadError", "File size is too small");
        return View(viewModel);
    }

    // check file extension

    string extension = Path.GetExtension(Request.Files[0].FileName).ToLower();

    if (extension != ".pdf" && extension != ".doc" && extension != ".docx" && extension != ".rtf" && extension != ".txt")
    {
        ModelState.AddModelError("uploadError", "Supported file extensions: pdf, doc, docx, rtf, txt");
        return View(viewModel);
    }

    // extract only the filename
    var fileName = Path.GetFileName(Request.Files[0].FileName);

    // store the file inside ~/App_Data/uploads folder
    var path = Path.Combine(Server.MapPath("~/App_Data/uploads"), fileName);

    try
    {
        if (System.IO.File.Exists(path))
            System.IO.File.Delete(path);

        Request.Files[0].SaveAs(path);
    }
    catch (Exception)
    {
        ModelState.AddModelError("uploadError", "Can't save file to disk");
    }

    if(ModelState.IsValid)
    {
        // put your logic here

        return View("Success");
    }

    return View(viewModel);         
}

Make sure you have

@Html.ValidationMessage("uploadError")

in your view for validation errors.

Also keep in mind that default maximum request length is 4MB (maxRequestLength = 4096), to upload larger files you have to change this parameter in web.config:

<system.web>
    <httpRuntime maxRequestLength="40960" executionTimeout="1100" />

(40960 = 40 MB here).

Execution timeout is the whole number of seconds. You may want to change it to allow huge files uploads.

Functions in PHP can return only one variable. you could use variables with global scope, you can return array, or you can pass variable by reference to the function and than change value,.. but all of that will decrease readability of your code. I would suggest that you look into the classes.

This is what I use

args = {
        'batch_size': 32,
        'workers': 4,
        'train_dir': 'train',
        'val_dir': 'val',
        'lr': 1e-3,
        'momentum': 0.9,
        'weight_decay': 1e-4
    }
args = namedtuple('Args', ' '.join(list(args.keys())))(**args)

print (args.lr)

The problem arises when a different system grabs the $ variable. You have multiple $ variables being used as objects from multiple libraries, resulting in the error.

To solve it, use jQuery.noConflict just before your (function($){:

jQuery.noConflict();
(function($){
$.fn.pluginbutton = function (options) {

Roll your own with @Clockworks solution, or in Atom, choose the menu option Atom > Install Shell Commands. This creates two symlinks in /usr/local/bin

apm -> /Applications/Atom.app/Contents/Resources/app/apm/node_modules/.bin/apm
atom -> /Applications/Atom.app/Contents/Resources/app/atom.sh

The atom command lets you do exactly what you're asking. apmis the command line package manager.

An API is the interface through which you access someone elses code or through which someone else's code accesses yours. In effect the public methods and properties.

To get the names of current directory we can use getcwd() or dirname(__FILE__) but getcwd() and dirname(__FILE__) are not synonymous. They do exactly what their names are. If your code is running by referring a class in another file which exists in some other directory then these both methods will return different results.

For example if I am calling a class, from where these two functions are invoked and the class exists in some /controller/goodclass.php from /index.php then getcwd() will return '/ and dirname(__FILE__) will return /controller.

After installing Update 3 for Visual Studio 2015, I suddenly got the "This project is incompatible with the current version of Visual Studio" error message while opening my Cordova project (.jsproj Javascript project file)

To solve this:

• Go to Programs & Features
• Select the Microsoft Visual Studio 2015 installation and click Change
• Click Modify
• Install "HTML/Javascript (Apache Cordova) Update 10" of the Cross Platform Mobile Development section

Very simple in socket.io 1.3:

io.sockets.sockets - is an array containing the connected socket objects. If you stored the username in each socket, you can do:

io.sockets.sockets.map(function(e) {
    return e.username;
})

Boom. You have the names of all connected users.

You can also get this if you mix org.junit and org.junit.jupiter annotations inadvertently.

No, they are identical.

default(), for any value type (DateTime is a value type) will always call the parameterless constructor.

put a int infront of the all the voxelCoord's...Like this below :

patch = numpyImage [int(voxelCoord[0]),int(voxelCoord[1])- int(voxelWidth/2):int(voxelCoord[1])+int(voxelWidth/2),int(voxelCoord[2])-int(voxelWidth/2):int(voxelCoord[2])+int(voxelWidth/2)]

You could use this:

a = ((4.0, 4, 4.0), (3.0, 3, 3.6), (3.5, 6, 4.8))
a = np.array(a)
a[:,0]
returns >>> array([4. , 3. , 3.5])

Simply replace image/jpeg with application/octet-stream. The client would not recognise the URL as an inline-able resource, and prompt a download dialog.

A simple JavaScript solution would be:

//var img = reference to image
var url = img.src.replace(/^data:image\/[^;]+/, 'data:application/octet-stream');
window.open(url);
// Or perhaps: location.href = url;
// Or even setting the location of an <iframe> element, 

Another method is to use a blob: URI:

var img = document.images[0];
img.onclick = function() {
    // atob to base64_decode the data-URI
    var image_data = atob(img.src.split(',')[1]);
    // Use typed arrays to convert the binary data to a Blob
    var arraybuffer = new ArrayBuffer(image_data.length);
    var view = new Uint8Array(arraybuffer);
    for (var i=0; i<image_data.length; i++) {
        view[i] = image_data.charCodeAt(i) & 0xff;
    }
    try {
        // This is the recommended method:
        var blob = new Blob([arraybuffer], {type: 'application/octet-stream'});
    } catch (e) {
        // The BlobBuilder API has been deprecated in favour of Blob, but older
        // browsers don't know about the Blob constructor
        // IE10 also supports BlobBuilder, but since the `Blob` constructor
        //  also works, there's no need to add `MSBlobBuilder`.
        var bb = new (window.WebKitBlobBuilder || window.MozBlobBuilder);
        bb.append(arraybuffer);
        var blob = bb.getBlob('application/octet-stream'); // <-- Here's the Blob
    }

    // Use the URL object to create a temporary URL
    var url = (window.webkitURL || window.URL).createObjectURL(blob);
    location.href = url; // <-- Download!
};

I'm late i think :] soory,

If you are here like me searching for the solution when this error occurs with mysqldump instead of mysql, try this solution that i found on a german website out there by chance, so i wanted to share with homeless people who got headaches like me.

So the problem occurs because the lack -databases parameter before the database name

So your command must look like this:

mysqldump -pdbpass -udbuser --databases dbname

Another cause of the problem in my case was that i'm developping on local and the root user doesn't have a password, so in this case you must use --password= instead of -pdbpass, so my final command was:

mysqldump -udbuser --password= --databases dbname

Link to the complete thread (in German) : https://marius.bloggt-in-braunschweig.de/2016/04/29/solution-mysqldump-no-database-selected-when-selecting-the-database/

To install SOAP in PHP5.6 run following in your Ubuntu 14.04 terminal:

sudo apt-get install php5.6-soap
service php5.6-fpm restart
service apache2 restart

See if SOAP was enabled:

php -m

(You should see SOAP between returned text.)

As a complementary, to produce patch for only one specific commit, use:

git format-patch -1 <sha>

When the patch file is generated, make sure your other repo knows where it is when you use git am ${patch-name}

Before adding the patch, use git apply --check ${patch-name} to make sure that there is no confict.

If you want to get the back arrow on a Toolbar that's not set as your SupportActionBar:

(kotlin)

val resId = getResIdFromAttribute(toolbar.context, android.R.attr.homeAsUpIndicator)
toolbarFilter.navigationIcon = ContextCompat.getDrawable(toolbar.context, resId)
toolbarFilter.setNavigationOnClickListener { fragmentManager?.popBackStack() }

to get res from attributes:

@AnyRes
fun getResIdFromAttribute(context: Context, @AttrRes attr: Int): Int {
    if (attr == 0) return 0
    val typedValueAttr = TypedValue()
    context.theme.resolveAttribute(attr, typedValueAttr, true)
    return typedValueAttr.resourceId
}

I solved mine using the whole url of the PDF file (Instead of just putting the file name or location to href): a href="domain . com/pdf/filename.pdf"

If you use private static variables in your class, Static Inner classes in your class can reach your variables. This is perfectly good for context security.

For calling the method of one class within the second class, you have to first create the object of that class which method you want to call than with the object reference you can call the method.

class A {
   public void fun(){
     //do something
   }
}

class B {
   public static void main(String args[]){
     A obj = new A();
     obj.fun();
   }
}

But in your case you have the static method in Date and TemperatureRange class. You can call your static method by using the class name directly like below code or by creating the object of that class like above code but static method ,mostly we use for creating the utility classes, so best way to call the method by using class name. Like in your case -

public static void main (String[] args){
  String dateVal = Date.date("01","11,"12"); // calling the date function by passing some parameter.

  String tempRangeVal = TemperatureRange.TempRange("80","20"); 
}

You don't say which database you are using but in MS SQL Server it would be

WHERE DateField = {d '2008-12-20'}

If it is a timestamp field then you'll need a range:

WHERE DateField BETWEEN {ts '2008-12-20 00:00:00'} AND {ts '2008-12-20 23:59:59'}

What type of OS are you running on?

In order to assign more than 2GB of ram it needs to be at least a 64bit OS.

Then there is another problem. Even if your OS has Unlimited RAM, but that is fragmented in a way that not a single free block of 2GB is available, you'll get out of memory exceptions too. And keep in mind that the normal Heap memory is only part of the memory the VM process is using. So on a 32bit machine you will probably never be able to set Xmx to 2048MB.

I would also suggest to set min an max memory to the same value, because in this case as soon as the VM runs out of memory the frist time 1GB is allocated from the start, the VM then allocates a new block (assuming it increases with 500MB blocks) of 1,5GB after that is allocated, it would copy all the stuff from block one to the new one and free Memory after that. If it runs out of Memory again the 2GB are allocated and the 1,5 GB are then copied, temporarily allocating 3,5GB of memory.

To get more information use this custom TO($someObject) function:

I wrote this simple function which not only displays the methods of a given object, but also shows its properties, encapsulation and some other useful information like release notes if given.

function TO($object){ //Test Object
                if(!is_object($object)){
                    throw new Exception("This is not a Object"); 
                    return;
                }
                if(class_exists(get_class($object), true)) echo "<pre>CLASS NAME = ".get_class($object);
                $reflection = new ReflectionClass(get_class($object));
                echo "<br />";
                echo $reflection->getDocComment();

                echo "<br />";

                $metody = $reflection->getMethods();
                foreach($metody as $key => $value){
                    echo "<br />". $value;
                }

                echo "<br />";

                $vars = $reflection->getProperties();
                foreach($vars as $key => $value){
                    echo "<br />". $value;
                }
                echo "</pre>";
            }

To show you how it works I will create now some random example class. Lets create class called Person and lets place some release notes just above the class declaration:

        /**
         * DocNotes -  This is description of this class if given else it will display false
         */
        class Person{
            private $name;
            private $dob;
            private $height;
            private $weight;
            private static $num;

            function __construct($dbo, $height, $weight, $name) {
                $this->dob = $dbo;
                $this->height = (integer)$height;
                $this->weight = (integer)$weight;
                $this->name = $name;
                self::$num++;

            }
            public function eat($var="", $sar=""){
                echo $var;
            }
            public function potrzeba($var =""){
                return $var;
            }
        }

Now lets create a instance of a Person and wrap it with our function.

    $Wictor = new Person("27.04.1987", 170, 70, "Wictor");
    TO($Wictor);

This will output information about the class name, parameters and methods including encapsulation information and the number of parameters, names of parameters for each method, method location and lines of code where it exists. See the output below:

CLASS NAME = Person
/**
             * DocNotes -  This is description of this class if given else it will display false
             */

Android Studio 2.2 has APK Analyzer it will give lot of info about apk, checkout it here :- http://android-developers.blogspot.in/2016/05/android-studio-22-preview-new-ui.html

Just select the Eclipse version of the keycap in the Keymap settings. An Eclipse Keymap is included in Android Studio.

Try:

With DependencedIncidents AS
(
    SELECT INC.[RecTime],INC.[SQL] AS [str] FROM
    (
        SELECT A.[RecTime] As [RecTime],X.[SQL] As [SQL] FROM [EventView] AS A 
        CROSS JOIN [Incident] AS X
            WHERE
                patindex('%' + A.[Col] + '%', X.[SQL]) > 0
    ) AS INC
),
lalala AS
(
    SELECT INC.[RecTime],INC.[SQL] AS [str] FROM
    (
        SELECT A.[RecTime] As [RecTime],X.[SQL] As [SQL] FROM [EventView] AS A 
        CROSS JOIN [Incident] AS X
            WHERE
                patindex('%' + A.[Col] + '%', X.[SQL]) > 0
    ) AS INC
)

And yes, you can reference common table expression inside common table expression definition. Even recursively. Which leads to some very neat tricks.

First step: see if postgres has a repository with prebuilt binaries for the version you want for your OS: https://www.postgresql.org/download/

If that doesn't work (for instance if your distro is there but is no longer supported, so correct binaries aren't provided for it), or if you just want to go straight or the source and not have to worry about adding remote repo's, etc.

What I did is download the raw source of postgres for the desired version.

Untar it, cd into it, build it ./configure && make, then:

postgresql-12.3 $ find . -name pg_dump
./src/bin/pg_dump/pg_dump
$ ./src/bin/pg_dump/pg_dump


unable to load libpg.so.5 # if it says this...
$ find . -name libpg.so.5
$ export LD_LIBRARY_PATH=/your/path/to/the/shared/dir/of/above/file

$ ./src/bin/pg_dump/pg_dump # works now

Now you have access to any version that builds on your box. Which should be any.

You may find out you want to use the same config for more domains.

Following snippet removes www before any domain:

if ($host ~* ^www\.(.*)$) {
    rewrite / $scheme://$1 permanent;
}

Also, SimpleDateFormat is not available with some of the client-side technologies, like GWT.

It's a good idea to go for Calendar.getInstance(), and your requirement is to compare two dates; go for long date.

This could be because your CSV file has embedded single or double quotes. If your CSV file is tab-delimited try opening it as:

c = csv.reader(f, delimiter='\t', quoting=csv.QUOTE_NONE)

The simplest way to get file extension in PHP is to use PHP's built-in function pathinfo.

$file_ext = pathinfo('your_file_name_here', PATHINFO_EXTENSION);
echo ($file_ext); // The output should be the extension of the file e.g., png, gif, or html

In my windows 10 Enterprise edition os this code works fine: (suppose for environment namely testenv)

conda env remove --name testenv

S3 does not have directories, while you can list files in a pseudo directory manner like you demonstrated, there is no directory "file" per-se.
You may of inadvertently created a data file called users/<user-id>/contacts/<contact-id>/.

Shortest form for small text files (in Kotlin):

val reader = FileReader(path)
val txt = reader.readText()
reader.close()

I actual ran into the same requirement. I simply used CSS override like this

.navbar .btn-toolbar { margin-top: 0; margin-bottom: 0 }

The sad state of "record separators" or "line terminators" is a legacy of the dark ages of computing.

Now, we take it for granted that anything we want to represent is in some way structured data and conforms to various abstractions that define lines, files, protocols, messages, markup, whatever.

But once upon a time this wasn't exactly true. Applications built-in control characters and device-specific processing. The brain-dead systems that required both CR and LF simply had no abstraction for record separators or line terminators. The CR was necessary in order to get the teletype or video display to return to column one and the LF (today, NL, same code) was necessary to get it to advance to the next line. I guess the idea of doing something other than dumping the raw data to the device was too complex.

Unix and Mac actually specified an abstraction for the line end, imagine that. Sadly, they specified different ones. (Unix, ahem, came first.) And naturally, they used a control code that was already "close" to S.O.P.

Since almost all of our operating software today is a descendent of Unix, Mac, or MS operating SW, we are stuck with the line ending confusion.

This worked for me:

find /A -type d -exec chmod 0755 {} \;
find /A -type f -exec chmod 0644 {} \;

First understand that you have three languages working together.

PHP: Is only run by the server and responds to requests like clicking on a link (GET) or submitting a form (POST). HTML & Javascript: Is only run in someone's browser (excluding NodeJS) I'm assuming your file looks something like:

<?php
function the_function() {
echo 'I just ran a php function';
 }

 if (isset($_GET['hello'])) {
  the_function();
  }
   ?>
  <html>
 <a href='the_script.php?hello=true'>Run PHP Function</a>
 </html>

Because PHP only responds to requests (GET, POST, PUT, PATCH, and DELETE via $_REQUEST) this is how you have to run a php function even though their in the same file. This gives you a level of security, "Should I run this script for this user or not?".

If you don't want to refresh the page you can make a request to PHP without refreshing via a method called Asynchronous Javascript and XML (AJAX).

Use the Base Context of the Activity in which your fragment resides to start an Intent.

Intent j = new Intent(fBaseCtx, NewactivityName.class);         
startActivity(j);

where fBaseCtx is BaseContext of your current activity. You can get it as fBaseCtx = getBaseContext();

You're looking for the Skip and Take extension methods. Skip moves past the first N elements in the result, returning the remainder; Take returns the first N elements in the result, dropping any remaining elements.

See MSDN for more information on how to use these methods: http://msdn.microsoft.com/en-us/library/bb386988.aspx

Assuming you are already taking into account that the pageNumber should start at 0 (decrease per 1 as suggested in the comments) You could do it like this:

int numberOfObjectsPerPage = 10;
var queryResultPage = queryResult
  .Skip(numberOfObjectsPerPage * pageNumber)
  .Take(numberOfObjectsPerPage);

Otherwise as suggested by @Alvin

int numberOfObjectsPerPage = 10;
var queryResultPage = queryResult
  .Skip(numberOfObjectsPerPage * (pageNumber - 1))
  .Take(numberOfObjectsPerPage);

This is all you need to know.

int state = 0;
while (state < 3)
{
    switch (state)
    {
        case 0:
            // Do State 0 Stuff
            if (should_go_to_next_state)
            {
                state++;
            }
            break;
        case 1:
            // Do State 1 Stuff    
            if (should_go_back) 
            {

            }    
            else if (should_go_to_next_state) 
            {
                state++;
            }
            break;
        case 2:
            // Do State 2 Stuff    
            if (should_go_back_two) 
            {
                state -= 2;
            }    
            else if (should_go_to_next_state) 
            {
                state++;
            }
            break;
        default:
            break;
    }
}

You have to validate the connection.

If you use Oracle it is likely that you use Oracle´s Universal Connection Pool. The following assumes that you do so.

The easiest way to validate the connection is to tell Oracle that the connection must be validated while borrowing it. This can be done with

pool.setValidateConnectionOnBorrow(true);

But it works only if you hold the connection for a short period. If you borrow the connection for a longer time, it is likely that the connection gets broken while you hold it. In that case you have to validate the connection explicitly with

if (connection == null || !((ValidConnection) connection).isValid())

See the Oracle documentation for further details.

Name- or Label-Based (using regular expression syntax)

df.filter(regex='[A-CEG-I]')   # does NOT depend on the column order

Note that any regular expression is allowed here, so this approach can be very general. E.g. if you wanted all columns starting with a capital or lowercase "A" you could use: df.filter(regex='^[Aa]')

Location-Based (depends on column order)

df[ list(df.loc[:,'A':'C']) + ['E'] + list(df.loc[:,'G':'I']) ]

Note that unlike the label-based method, this only works if your columns are alphabetically sorted. This is not necessarily a problem, however. For example, if your columns go ['A','C','B'], then you could replace 'A':'C' above with 'A':'B'.

The Long Way

And for completeness, you always have the option shown by @Magdalena of simply listing each column individually, although it could be much more verbose as the number of columns increases:

df[['A','B','C','E','G','H','I']]   # does NOT depend on the column order

Results for any of the above methods

          A         B         C         E         G         H         I
0 -0.814688 -1.060864 -0.008088  2.697203 -0.763874  1.793213 -0.019520

To remove need for ToString() call use

string actionName = ControllerContext.RouteData.GetRequiredString("action");
string controllerName = ControllerContext.RouteData.GetRequiredString("controller");

I think your best shot is a border-left property that is assigned to each one of the lis except the first one (You would have to give the first one a class named first and explicitly remove the border for that).

Even if you are generating the <li> programmatically, assigning a first class should be easy.

Rebasing and dropping commits are the best when you want to keep the history clean useful when proposing patches to a public branch etc.

If you have to drop the topmost commit then the following one-liner helps

git rebase --onto HEAD~1 HEAD

But if you want to drop 1 of many commits you did say

a -> b -> c -> d -> master

and you want to drop commit 'c'

git rebase --onto b c

This will make 'b' as the new base of 'd' eliminating 'c'

Here’s another algorithm for ensuring the numbers are unique:

1. generate an array of all the numbers from 0 to x
2. shuffle the array so the elements are in random order
3. pick the first n

Compared to the method of generating random numbers until you get a unique one, this method uses more memory, but it has a more stable running time – the results are guaranteed to be found in finite time. This method works better if the upper limit is relatively low or if the amount to take is relatively high.

My answer uses the Lodash library for simplicity, but you could also implement the algorithm described above without that library.

// assuming _ is the Lodash library

// generates `amount` numbers from 0 to `upperLimit` inclusive
function uniqueRandomInts(upperLimit, amount) {
    var possibleNumbers = _.range(upperLimit + 1);
    var shuffled = _.shuffle(possibleNumbers);
    return shuffled.slice(0, amount);
}

use this code

  while ($rows = mysql_fetch_array($query)):

   $name = $rows['Name'];
   $address = $rows['Address'];
   $email = $rows['Email'];
   $subject = $rows['Subject'];
   $comment = $rows['Comment'];

   echo "$name<br>$address<br>$email<br>$subject<br>$comment<br><br>";

   endwhile;

   ?>

If you open a device using png(), bmp(), pdf() etc. as suggested by Andrie (the best answer), the windows with plots will not pop up open, just *.png, *bmp or *.pdf files will be created. This is convenient in massive calculations, since R can handle only limited number of graphic windows.

However, if you want to see the plots and also have them saved, call savePlot(filename, type) after the plots are drawn and the window containing them is active.

Both will generate the same columns when you run the migration. In rails console, you can see that this is the case:

:001 > Micropost
=> Micropost(id: integer, user_id: integer, created_at: datetime, updated_at: datetime)

The second command adds a belongs_to :user relationship in your Micropost model whereas the first does not. When this relationship is specified, ActiveRecord will assume that the foreign key is kept in the user_id column and it will use a model named User to instantiate the specific user.

The second command also adds an index on the new user_id column.

My first guess is that LaTeX chokes on | outside a math environment. Missing $ inserted is usually a symptom of something like that.

200 is just the normal HTTP header for a successful request. If that's all you need, just have the controller return new EmptyResult();

You need to slightly modify your compare function and use functools.cmp_to_key to pass it to sorted. Example code:

import functools

lst = [list(range(i, i+5)) for i in range(5, 1, -1)]

def fitness(item):
    return item[0]+item[1]+item[2]+item[3]+item[4]
def compare(item1, item2):
    return fitness(item1) - fitness(item2)

sorted(lst, key=functools.cmp_to_key(compare))

Output:

[[2, 3, 4, 5, 6], [3, 4, 5, 6, 7], [4, 5, 6, 7, 8], [5, 6, 7, 8, 9]]

Works :)

Assuming you're using WinForms, as it was the first thing I did when I was starting C# you need to create an event to close this form.

Lets say you've got a button called myNewButton. If you double click it on WinForms designer you will create an event. After that you just have to use this.Close

    private void myNewButton_Click(object sender, EventArgs e) {
        this.Close();
    }

And that should be it.

The only reason for this not working is that your Event is detached from button. But it should create new event if old one is no longer attached when you double click on the button in WinForms designer.

This problem is caused when including <windows.h> before <winsock2.h>. Try arrange your include list that <windows.h> is included after <winsock2.h> or define _WINSOCKAPI_ first:

#define _WINSOCKAPI_    // stops windows.h including winsock.h
#include <windows.h>
// ...
#include "MyClass.h"    // Which includes <winsock2.h>

Like most form controls in HTML, the results of applying CSS to <select> and <option> elements vary a lot between browsers. Chrome, as you've found, won't let you apply and font styles to an <option> element directly --- if you do Inspect Element on it, you'll see the font-size: 14px declaration is crossed through as if it's been overridden by the cascade, but it's actually because Chrome is ignoring it.

However, Chrome will let you apply font styles to the <optgroup> element, so to achieve the result you want you can wrap all the <option>s in an <optgroup> and then apply your font styles to a .styled-select optgroup selector. If you want the optgroup sans-label, you may have to do some clever CSS with positioning or something to hide the white area at the top where the label would be shown, but that should be possible.

Forked to a new JSFiddle to show you what I mean:

http://jsfiddle.net/zRtbZ/

Simply use the graph API with this url format: https://graph.facebook.com/[email protected]&type=user&access_token=... You can easily create an application here and grab an access token for it here. I believe you get an estimated 600 requests per 600 seconds, although this isn't documented.

If you are doing this in bulk, you could use batch requests in batches of 20 email addresses. This may help with rate limits (I am not sure if you get 600 batch requests per 600 seconds or 600 individual requests).

Well, if you study the structure of how the application life-cycle works,here , then you'll come to know that onPause() is called when another activity gains focus, and onStop() is called when the activity is no longer visible.

From what I have learned yet, you can call finish() only from the activity which is active and/or has the focus. If you're calling finish() from the onPause() method that means you're calling it when the activity is no longer active. thus an exception is thrown.

When you're calling finish() from onStop() then the activity is being sent to background, thus will no longer be visible, then this exception.

When you press the back button, onStop() is called.

Most probably, Android will automatically do for you what you are currently wanting to do.

//JAVA
    public Double getDistanceBetweenTwoPoints(Double latitude1, Double longitude1, Double latitude2, Double longitude2) {
    final int RADIUS_EARTH = 6371;

    double dLat = getRad(latitude2 - latitude1);
    double dLong = getRad(longitude2 - longitude1);

    double a = Math.sin(dLat / 2) * Math.sin(dLat / 2) + Math.cos(getRad(latitude1)) * Math.cos(getRad(latitude2)) * Math.sin(dLong / 2) * Math.sin(dLong / 2);
    double c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1 - a));
    return (RADIUS_EARTH * c) * 1000;
    }

    private Double getRad(Double x) {
    return x * Math.PI / 180;
    }

If you are getting io.set not a function or io.origins not a function, you can try such notation:

import express from 'express';
import { Server } from 'socket.io';
const app = express();
const server = app.listen(3000);
const io = new Server(server, { cors: { origin: '*' } });

As others have mentioned, perhaps the main advantage of matrix was that it provided a convenient notation for matrix multiplication.

However, in Python 3.5 there is finally a dedicated infix operator for matrix multiplication: @.

With recent NumPy versions, it can be used with ndarrays:

A = numpy.ones((1, 3))
B = numpy.ones((3, 3))
A @ B

So nowadays, even more, when in doubt, you should stick to ndarray.

There are many ways to create a Set and a List. HashSet and ArrayList are just two examples. It is also fairly common to use generics with collections these days. I suggest you have a look at what they are

This is a good introduction for java's builtin collections. http://java.sun.com/javase/6/docs/technotes/guides/collections/overview.html

Generics solution to covert any List<Type> to String []:

public static  <T> String[] listToArray(List<T> list) {
    String [] array = new String[list.size()];
    for (int i = 0; i < array.length; i++)
        array[i] = list.get(i).toString();
    return array;
}

Note You must override toString() method.

class Car {
  private String name;
  public Car(String name) {
    this.name = name;
  }
  public String toString() {
    return name;
  }
}
final List<Car> carList = new ArrayList<Car>();
carList.add(new Car("BMW"))
carList.add(new Car("Mercedes"))
carList.add(new Car("Skoda"))
final String[] carArray = listToArray(carList);

A "sort merge" join is performed by sorting the two data sets to be joined according to the join keys and then merging them together. The merge is very cheap, but the sort can be prohibitively expensive especially if the sort spills to disk. The cost of the sort can be lowered if one of the data sets can be accessed in sorted order via an index, although accessing a high proportion of blocks of a table via an index scan can also be very expensive in comparison to a full table scan.

A hash join is performed by hashing one data set into memory based on join columns and reading the other one and probing the hash table for matches. The hash join is very low cost when the hash table can be held entirely in memory, with the total cost amounting to very little more than the cost of reading the data sets. The cost rises if the hash table has to be spilled to disk in a one-pass sort, and rises considerably for a multipass sort.

(In pre-10g, outer joins from a large to a small table were problematic performance-wise, as the optimiser could not resolve the need to access the smaller table first for a hash join, but the larger table first for an outer join. Consequently hash joins were not available in this situation).

The cost of a hash join can be reduced by partitioning both tables on the join key(s). This allows the optimiser to infer that rows from a partition in one table will only find a match in a particular partition of the other table, and for tables having n partitions the hash join is executed as n independent hash joins. This has the following effects:

1. The size of each hash table is reduced, hence reducing the maximum amount of memory required and potentially removing the need for the operation to require temporary disk space.
2. For parallel query operations the amount of inter-process messaging is vastly reduced, reducing CPU usage and improving performance, as each hash join can be performed by one pair of PQ processes.
3. For non-parallel query operations the memory requirement is reduced by a factor of n, and the first rows are projected from the query earlier.

You should note that hash joins can only be used for equi-joins, but merge joins are more flexible.

In general, if you are joining large amounts of data in an equi-join then a hash join is going to be a better bet.

This topic is very well covered in the documentation.

http://download.oracle.com/docs/cd/B28359_01/server.111/b28274/optimops.htm#i51523

UPDATE: As this answer is still getting votes both up and down, and is at the time of writing eight years old: There are probably better techniques out there now. Original answer follows below.

Clearly you are looking for the Faux columns technique :-)

By how the height-property is calculated, you can't set height: 100% inside something that has auto-height.

Use something such as the following:

if (String.IsNullOrEmpty(MaterialTextBox.Text)) 

If you are inside the fragment then you write the following line of code inside your on click listener, getActivity().onBackPressed(); this works perfectly for me.

If you are working in ROOT, you do not even have to write #include<iostream> and using namespace std; simply start from int filename().

This will solve the issue.

You could write a directive for this, which simply assigns the (jqLite) element to the scope using an attribute-given name.

Here is the directive:

app.directive("ngScopeElement", function () {
  var directiveDefinitionObject = {

    restrict: "A",

    compile: function compile(tElement, tAttrs, transclude) {
      return {
          pre: function preLink(scope, iElement, iAttrs, controller) {
            scope[iAttrs.ngScopeElement] = iElement;
          }
        };
    }
  };

  return directiveDefinitionObject;
});

Usage:

app.directive("myDirective", function() {
    return {
        template: '<div><ul ng-scope-element="list"><li ng-repeat="item in items"></ul></div>',
        link: function(scope, element, attrs) {
            scope.list[0] // scope.list is the jqlite element, 
                          // scope.list[0] is the native dom element
        }
    }
});

Some remarks:

• Due to the compile and link order for nested directives you can only access scope.list from myDirectives postLink-Function, which you are very likely using anyway
• ngScopeElement uses a preLink-function, so that directives nested within the element having ng-scope-element can already access scope.list
• not sure how this behaves performance-wise

None of the above solutions worked for me. It's possible that there were some other styles conflicting.

For myself, the following worked, hopefully it may help someone else. I'm using bootstrap 4.

.carousel-inner img {       
   display:block;
   height: auto; 
   max-width: 100%;
}

You can also use the Filter button to filter tables with a certain string in it. You can do the same with stored procedures and views.

Update

Mongoose 5.7.1 was release and seems to fix the issue, so setting up the useUnifiedTopology option work as expected.

mongoose.connect(mongoConnectionString, {useNewUrlParser: true, useUnifiedTopology: true});

Original answer

I was facing the same issue and decided to deep dive on Mongoose code: https://github.com/Automattic/mongoose/search?q=useUnifiedTopology&unscoped_q=useUnifiedTopology

Seems to be an option added on version 5.7 of Mongoose and not well documented yet. I could not even find it mentioned in the library history https://github.com/Automattic/mongoose/blob/master/History.md

According to a comment in the code:

• @param {Boolean} [options.useUnifiedTopology=false] False by default. Set to true to opt in to the MongoDB driver's replica set and sharded cluster monitoring engine.

There is also an issue on the project GitHub about this error: https://github.com/Automattic/mongoose/issues/8156

In my case I don't use Mongoose in a replica set or sharded cluster and though the option should be false. But if false it complains the setting should be true. Once is true it still don't work, probably because my database does not run on a replica set or sharded cluster.

I've downgraded to 5.6.13 and my project is back working fine. So the only option I see for now is to downgrade it and wait for the fix to update for a newer version.

function to drop duplicate columns after joining.

check it

def dropDupeDfCols(df): newcols = [] dupcols = []

for i in range(len(df.columns)):
    if df.columns[i] not in newcols:
        newcols.append(df.columns[i])
    else:
        dupcols.append(i)

df = df.toDF(*[str(i) for i in range(len(df.columns))])
for dupcol in dupcols:
    df = df.drop(str(dupcol))

return df.toDF(*newcols)

I had this error when opening a CSV file and one of the fields had commas embedded in it. The field had quotes around it, and I had cut and paste the read.table with quote="" in it. Once I took quote="" out, the default behavior of read.table took over and killed the problem. So I went from this:

systems <- read.table("http://getfile.pl?test.csv", header=TRUE, sep=",", quote="")

to this:

systems <- read.table("http://getfile.pl?test.csv", header=TRUE, sep=",")

You can use the "Join" function to create a single string out of the array of labels, like this:

=Join(Parameters!Product.Label, ",")

I'm still getting my feet wet with Node.js, but I have a few ideas. first, I believe you need to use execFile instead of spawn; execFile is for when you have the path to a script, whereas spawn is for executing a well-known command that Node.js can resolve against your system path.

1. Provide a callback to process the buffered output:

var child = require('child_process').execFile('path/to/script', [ 
    'arg1', 'arg2', 'arg3', 
], function(err, stdout, stderr) { 
    // Node.js will invoke this callback when process terminates.
    console.log(stdout); 
});  

2. Add a listener to the child process' stdout stream (9thport.net)

var child = require('child_process').execFile('path/to/script', [ 
    'arg1', 'arg2', 'arg3' ]); 
// use event hooks to provide a callback to execute when data are available: 
child.stdout.on('data', function(data) {
    console.log(data.toString()); 
});

Further, there appear to be options whereby you can detach the spawned process from Node's controlling terminal, which would allow it to run asynchronously. I haven't tested this yet, but there are examples in the API docs that go something like this:

child = require('child_process').execFile('path/to/script', [ 
    'arg1', 'arg2', 'arg3', 
], { 
    // detachment and ignored stdin are the key here: 
    detached: true, 
    stdio: [ 'ignore', 1, 2 ]
}); 
// and unref() somehow disentangles the child's event loop from the parent's: 
child.unref(); 
child.stdout.on('data', function(data) {
    console.log(data.toString()); 
});

If you're accessing this via a View then try sp_recompile or refreshing views.

sp_recompile:

Causes stored procedures, triggers, and user-defined functions to be recompiled the next time that they are run. It does this by dropping the existing plan from the procedure cache forcing a new plan to be created the next time that the procedure or trigger is run. In a SQL Server Profiler collection, the event SP:CacheInsert is logged instead of the event SP:Recompile.

Arguments

[ @objname= ] 'object'

The qualified or unqualified name of a stored procedure, trigger, table, view, or user-defined function in the current database. object is nvarchar(776), with no default. If object is the name of a stored procedure, trigger, or user-defined function, the stored procedure, trigger, or function will be recompiled the next time that it is run. If object is the name of a table or view, all the stored procedures, triggers, or user-defined functions that reference the table or view will be recompiled the next time that they are run.

Return Code Values

0 (success) or a nonzero number (failure)

Remarks

sp_recompile looks for an object in the current database only.

The queries used by stored procedures, or triggers, and user-defined functions are optimized only when they are compiled. As indexes or other changes that affect statistics are made to the database, compiled stored procedures, triggers, and user-defined functions may lose efficiency. By recompiling stored procedures and triggers that act on a table, you can reoptimize the queries.

Attention: This method saves the credentials in plaintext on your PC's disk. Everyone on your computer can access it, e.g. malicious NPM modules.

Run

git config --global credential.helper store

then

git pull

provide a username and password and those details will then be remembered later. The credentials are stored in a file on the disk, with the disk permissions of "just user readable/writable" but still in plaintext.

If you want to change the password later

git pull

Will fail, because the password is incorrect, git then removes the offending user+password from the ~/.git-credentials file, so now re-run

git pull

to provide a new password so it works as earlier.

There are two BeanUtils.copyProperties(parameter1, parameter2) in Java.

One is

org.apache.commons.beanutils.BeanUtils.copyProperties(Object dest, Object orig)

Another is

org.springframework.beans.BeanUtils.copyProperties(Object source, Object target)

Pay attention to the opposite position of parameters.

The package you're looking for is confusingly named gcc-c++.

From @Jon Skeet comment, really the String value is "null". Following code solved it

if (userEmail != null && !userEmail.isEmpty() && !userEmail.equals("null")) 

you can try chsh -s /bin/bash to set the bash as the default, or chsh -s /bin/zsh to set the zsh as the default.

Terminal will need a restart to take effect.

for (int j=0; j<test.length; j++) {
   System.out.format("%02X ", test[j]);
}
System.out.println();

Uncomment this line (in /conf/logging.properties)

Do you mean to property files located in src/main/resources? Then you should exclude them using the maven-resource-plugin. See the following page for details:

http://maven.apache.org/plugins/maven-resources-plugin/examples/include-exclude.html

If you have just added the submodule, and for example, you simply added the wrong submodule or you added it to the wrong place, simply do git stash then delete the folder. This is assuming that adding the submodule is the only thing you did in the recent repo.

The best way to view and manage your Android app database is to use the library DatabaseManager_For_Android.

It's a single Java activity file; just add it to your source folder. You can view the tables in your app database, update, delete, insert rows to you table. Everything from inside your app.

When the development is done remove the Java file from your src folder. That's it.

You can view the 5 minute demo, Database Manager for Android SQLite Database .

The example you copied from is using data in the form of an array holding arrays, you are using data in the form of an array holding objects. Objects and arrays are not the same, and because of this they use different syntaxes for accessing data.

If you don't know the variable names, just do a var_dump($blog); within the loop to see them.

The simplest method - access $blog as an object directly:

Try (assuming those variables are correct):

<?php 
    foreach ($blogs as $blog) {
        $id         = $blog->id;
        $title      = $blog->title;
        $content    = $blog->content;
?>

<h1> <?php echo $title; ?></h1>
<h1> <?php echo $content; ?> </h1>

<?php } ?>

The alternative method - access $blog as an array:

Alternatively, you may be able to turn $blog into an array with get_object_vars (documentation):

<?php
    foreach($blogs as &$blog) {
        $blog     = get_object_vars($blog);
        $id       = $blog['id'];
        $title    = $blog['title'];
        $content  = $blog['content'];
?>

<h1> <?php echo $title; ?></h1>
<h1> <?php echo $content; ?> </h1>

<?php } ?> 

It's worth mentioning that this isn't necessarily going to work with nested objects so its viability entirely depends on the structure of your $blog object.

Better than either of the above - Inline PHP Syntax

Having said all that, if you want to use PHP in the most readable way, neither of the above are right. When using PHP intermixed with HTML, it's considered best practice by many to use PHP's alternative syntax, this would reduce your whole code from nine to four lines:

<?php foreach($blogs as $blog): ?>
    <h1><?php echo $blog->title; ?></h1>
    <p><?php echo $blog->content; ?></p>
<?php endforeach; ?>

Hope this helped.

Use this snip : var IE = (navigator.userAgent.indexOf("Edge") > -1 || navigator.userAgent.indexOf("Trident/7.0") > -1) ? true : false;

You should include the brackets as well . . .

<input type="checkbox" name="bla[]" value="1" />

therefore referencing it should be as be name='bla[]'

$(document).ready( function () { 

   $("input[name='bla[]']").each( function () {
       alert( $(this).val() );
   });

});

The Builder pattern might be of use here. Today I had the same issue. where I needed Set mutating operations to return me a reference of the Set object, so I can pass it to super class constructor so that they too can continue adding to same set by in turn constructing a new StringSetBuilder off of the Set that the child class just built. The builder class I wrote looks like this (in my case it's a static inner class of an outer class, but it can be its own independent class as well):

public interface Builder<T> {
    T build();
}

static class StringSetBuilder implements Builder<Set<String>> {
    private final Set<String> set = new HashSet<>();

    StringSetBuilder add(String pStr) {
        set.add(pStr);
        return this;
    }

    StringSetBuilder addAll(Set<String> pSet) {
        set.addAll(pSet);
        return this;
    }

    @Override
    public Set<String> build() {
        return set;
    }
}

Notice the addAll() and add() methods, which are Set returning counterparts of Set.add() and Set.addAll(). Finally notice the build() method, which returns a reference to the Set that the builder encapsulates. Below illustrates then how to use this Set builder:

class SomeChildClass extends ParentClass {
    public SomeChildClass(String pStr) {
        super(new StringSetBuilder().add(pStr).build());
    }
}

class ParentClass {
    public ParentClass(Set<String> pSet) {
        super(new StringSetBuilder().addAll(pSet).add("my own str").build());
    }
}

if(n==1 || n==0){
    return n;
}else{     
    return fib(n-1) + fib(n-2);
}

However, using recursion to get fibonacci number is bad practice, because function is called about 8.5 times than received number. E.g. to get fibonacci number of 30 (1346269) - function is called 7049122 times!

Use InetAddress.getLocalHost() to get the local address

import java.net.InetAddress;

try {
  InetAddress addr = InetAddress.getLocalHost();            
  System.out.println(addr.getHostAddress());
} catch (UnknownHostException e) {
}

select username,
       account_status 
  from dba_users 
 where lock_date is not null;

This will actually give you the list of locked users.
