Please consider using some code like this:

SqlDataReader reader = command.ExecuteReader();
int numRows = 0;
DataTable dt = new DataTable();

dt.Load(reader);
numRows = dt.Rows.Count;

string attended_type = "";

for (int index = 0; index < numRows; index++)
{
    attended_type = dt.Rows[indice2]["columnname"].ToString();
}

reader.Close();

There is also another straight and more clear way

git commit -m "Title" -m "Description ..........";

mRadioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(RadioGroup radioGroup, int i) {
            if (mRadioButtonMale.isChecked()) {
                text = "male";
            } else {
                text = "female";
            }
        }
    });

OR

 mRadioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(RadioGroup radioGroup, int i) {
            if (mRadioButtonMale.isChecked()) { text = "male"; }
            if(mRadioButtonFemale.isChecked()) { text = "female"; }
        }
    });

Can I just ask about the long term need for this facility - is it for debuging purposes?

If so, then you may want to consider using a proper debugger, such as the one found in Visual Studio, as this allows you to step through the procedure in a more controlled way, and avoids having to constantly add/remove PRINT statement from the procedure.

Just my opinion, but I prefer the debugger approach - for code and databases.

Since the introduction of Visual Studio 2015, this location has changed and is added into your solution root under the following location:

C:\<Path\To\Solution>\.vs\config\applicationhost.config

I hope this saves you some time!

Read the info.plist file of your app and get the value for key CFBundleShortVersionString. Reading info.plist will give you an NSDictionary object

Your code works fine.

def list = [["c":"d"], ["e":"f"], ["g":"h"]]
Map tmpHM = [1:"second (e:f)", 0:"first (c:d)", 2:"third (g:h)"]

for (objKey in tmpHM.keySet()) {   
    HashMap objHM = (HashMap) list.get(objKey);
    print("objHM: ${objHM}  , ")
}

prints objHM: [e:f] , objHM: [c:d] , objHM: [g:h] ,

I came here searching solution for Ranorex Studio 9.0.1. There is no contains() there yet. Instead we can use regex like:

div[@class~'atag']

One way to do it :

FileStream stream = File.Open(@"c:\working\test.xls", FileMode.Open, FileAccess.Read);

IExcelDataReader excelReader = ExcelReaderFactory.CreateBinaryReader(stream);

excelReader.IsFirstRowAsColumnNames = true;

DataSet result = excelReader.AsDataSet();

The result.Tables contains the sheets and the result.tables[0].Rows contains the cell rows.

As variant, use simple lib > http://codeproject.com/Articles/42035/Enum-to-String-and-Vice-Versa-in-C

In the code

#include <EnumString.h>

enum FORM {
    F_NONE = 0,
    F_BOX,
    F_CUBE,
    F_SPHERE,
};

add lines

Begin_Enum_String( FORM )
{
    Enum_String( F_NONE );
    Enum_String( F_BOX );
    Enum_String( F_CUBE );
    Enum_String( F_SPHERE );
}
End_Enum_String;

Work fine, if values in enum are not dublicate.

Example usage

enum FORM f = ...
const std::string& str = EnumString< FORM >::From( f );

and vice versa

assert( EnumString< FORM >::To( f, str ) );

You can open the other file and type :r file_to_be_copied_from. Or you can buffer. Or go to the first file, go on the line you want to copy, type "qY, go to the file you want to paste and type "qP.

"buffer_name, copies to the buffer. Y is yank and P is put. Hope that helps!

1. You need to make sure that sanitize.js is loaded. For example, load it from https://ajax.googleapis.com/ajax/libs/angularjs/[LAST_VERSION]/angular-sanitize.min.js
2. you need to include ngSanitize module on your app eg: var app = angular.module('myApp', ['ngSanitize']);
3. you just need to bind with ng-bind-html the original html content. No need to do anything else in your controller. The parsing and conversion is automatically done by the ngBindHtml directive. (Read the How does it work section on this: $sce). So, in your case <div ng-bind-html="preview_data.preview.embed.html"></div> would do the work.

All fields in JavaScript (and in TypeScript) can have the value null or undefined.

You can make the field optional which is different from nullable.

interface Employee1 {
    name: string;
    salary: number;
}

var a: Employee1 = { name: 'Bob', salary: 40000 }; // OK
var b: Employee1 = { name: 'Bob' }; // Not OK, you must have 'salary'
var c: Employee1 = { name: 'Bob', salary: undefined }; // OK
var d: Employee1 = { name: null, salary: undefined }; // OK

// OK
class SomeEmployeeA implements Employee1 {
    public name = 'Bob';
    public salary = 40000;
}

// Not OK: Must have 'salary'
class SomeEmployeeB implements Employee1 {
    public name: string;
}

Compare with:

interface Employee2 {
    name: string;
    salary?: number;
}

var a: Employee2 = { name: 'Bob', salary: 40000 }; // OK
var b: Employee2 = { name: 'Bob' }; // OK
var c: Employee2 = { name: 'Bob', salary: undefined }; // OK
var d: Employee2 = { name: null, salary: 'bob' }; // Not OK, salary must be a number

// OK, but doesn't make too much sense
class SomeEmployeeA implements Employee2 {
    public name = 'Bob';
}

With a vector iterators do no offer any real advantage. The syntax is uglier, longer to type and harder to read.

Iterating over a vector using iterators is not faster and is not safer (actually if the vector is possibly resized during the iteration using iterators will put you in big troubles).

The idea of having a generic loop that works when you will change later the container type is also mostly nonsense in real cases. Unfortunately the dark side of a strictly typed language without serious typing inference (a bit better now with C++11, however) is that you need to say what is the type of everything at each step. If you change your mind later you will still need to go around and change everything. Moreover different containers have very different trade-offs and changing container type is not something that happens that often.

The only case in which iteration should be kept if possible generic is when writing template code, but that (I hope for you) is not the most frequent case.

The only problem present in your explicit index loop is that size returns an unsigned value (a design bug of C++) and comparison between signed and unsigned is dangerous and surprising, so better avoided. If you use a decent compiler with warnings enabled there should be a diagnostic on that.

Note that the solution is not to use an unsiged as the index, because arithmetic between unsigned values is also apparently illogical (it's modulo arithmetic, and x-1 may be bigger than x). You instead should cast the size to an integer before using it. It may make some sense to use unsigned sizes and indexes (paying a LOT of attention to every expression you write) only if you're working on a 16 bit C++ implementation (16 bit was the reason for having unsigned values in sizes).

As a typical mistake that unsigned size may introduce consider:

void drawPolyline(const std::vector<P2d>& points)
{
    for (int i=0; i<points.size()-1; i++)
        drawLine(points[i], points[i+1]);
}

Here the bug is present because if you pass an empty points vector the value points.size()-1 will be a huge positive number, making you looping into a segfault. A working solution could be

for (int i=1; i<points.size(); i++)
    drawLine(points[i - 1], points[i]);

but I personally prefer to always remove unsinged-ness with int(v.size()).

PS: If you really don't want to think by to yourself to the implications and simply want an expert to tell you then consider that a quite a few world recognized C++ experts agree and expressed opinions on that unsigned values are a bad idea except for bit manipulations.

Discovering the ugliness of using iterators in the case of iterating up to second-last is left as an exercise for the reader.

echo(var_export($var)); 

When $var is boolean variable, true or false will be printed out.

Sure, use the .format method. E.g.,

print('{:10s} {:3d}  {:7.2f}'.format('xxx', 123, 98))
print('{:10s} {:3d}  {:7.2f}'.format('yyyy', 3, 1.0))
print('{:10s} {:3d}  {:7.2f}'.format('zz', 42, 123.34))

will print

xxx        123    98.00
yyyy         3     1.00
zz          42   123.34

You can adjust the field sizes as desired. Note that .format works independently of print to format a string. I just used print to display the strings. Brief explanation:

10s format a string with 10 spaces, left justified by default

3d format an integer reserving 3 spaces, right justified by default

7.2f format a float, reserving 7 spaces, 2 after the decimal point, right justfied by default.

There are many additional options to position/format strings (padding, left/right justify etc), String Formatting Operations will provide more information.

Update for f-string mode. E.g.,

text, number, other_number = 'xxx', 123, 98
print(f'{text:10} {number:3d}  {other_number:7.2f}')

For right alignment

print(f'{text:>10} {number:3d}  {other_number:7.2f}')

You are not actually changing the function.

onClick is assigned to a function (Which is a reference to something, a function pointer in this case). The values passed to it don't matter and cannot be utilised in any manner.

Another problem is your variable color seems out of nowhere.

Ideally, inside the function you should put this logic and let it figure out what to write. (on/off etc etc)

var a = [1,2,3];

if ( a.indexOf( 1 ) !== -1 ) { }

Note that indexOf is not in the core ECMAScript. You'll need to have a snippet for IE and possibly other browsers that dont support Array.prototype.indexOf.

if (!Array.prototype.indexOf)
{
  Array.prototype.indexOf = function(searchElement /*, fromIndex */)
  {
    "use strict";

    if (this === void 0 || this === null)
      throw new TypeError();

    var t = Object(this);
    var len = t.length >>> 0;
    if (len === 0)
      return -1;

    var n = 0;
    if (arguments.length > 0)
    {
      n = Number(arguments[1]);
      if (n !== n)
        n = 0;
      else if (n !== 0 && n !== (1 / 0) && n !== -(1 / 0))
        n = (n > 0 || -1) * Math.floor(Math.abs(n));
    }

    if (n >= len)
      return -1;

    var k = n >= 0
          ? n
          : Math.max(len - Math.abs(n), 0);

    for (; k < len; k++)
    {
      if (k in t && t[k] === searchElement)
        return k;
    }
    return -1;
  };
}

To quote Wikipedia:

ACID (atomicity, consistency, isolation, durability) is a set of properties that guarantee database transactions are processed reliably.

A DBMS that supports transactions will strive to support all of these properties - any commercial DBMS (as well as several open-source DBMSs) provide full ACID 'support' - although it's often possible (for example, with varying isolation levels in MSSQL) to lessen the ACIDness - thus losing the guarantee of fully transactional behaviour.

There are 3 ways to check for "not null". My recommendation is to use the Strict Not Version.

1. Strict Not Version

if (val !== null) { ... }

The Strict Not Version uses the "Strict Equality Comparison Algorithm" http://www.ecma-international.org/ecma-262/5.1/#sec-11.9.6. The !== has faster performance, than the != operator because the Strict Equality Comparison Algorithm doesn't typecast values.

2. Non-strict Not Version

if (val != 'null') { ... }

The Non-strict version uses the "Abstract Equality Comparison Algorithm" http://www.ecma-international.org/ecma-262/5.1/#sec-11.9.3. The != has slower performance, than the !== operator because the Abstract Equality Comparison Algorithm typecasts values.

3. Double Not Version

if (!!val) { ... }

The Double Not Version !! has faster performance, than both the Strict Not Version !== and the Non-Strict Not Version != (https://jsperf.com/tfm-not-null/6). However, it will typecast "Falsey" values like undefined and NaN into False (http://www.ecma-international.org/ecma-262/5.1/#sec-9.2) which may lead to unexpected results, and it has worse readability because null isn't explicitly stated.

    public static void OpenDialog (Activity activity, DialogFragment fragment){

    final FragmentManager fm = ((FragmentActivity)activity).getSupportFragmentManager();

    fragment.show(fm, "tag");
}

You can use Date.getTime() function, or the Date object itself which when divided returns the time in milliseconds.

var d = new Date();

d/1000
> 1510329641.84

d.getTime()/1000
> 1510329641.84

To check if a value is Int in Mysql, we can use the following query. This query will give the rows with Int values

SELECT col1 FROM table WHERE concat('',col * 1) = col;

This is actually quite a complex question. Linq makes certain things very easy to do, that if you implement them yourself, you might stumble over (e.g. linq .Except()). This particularly applies to PLinq, and especially to parallel aggregation as implemented by PLinq.

In general, for identical code, linq will be slower, because of the overhead of delegate invocation.

If, however, you are processing a large array of data, and applying relatively simple calculations to the elements, you will get a huge performance increase if:

1. You use an array to store the data.

2. You use a for loop to access each element (as opposed to foreach or linq).

   • Note: When benchmarking, please everyone remember - if you use the same array/list for two consecutive tests, the CPU cache will make the second one faster. *

I think best approach is xian's answer.

but...

# Nested for loop

This approach is dirty, but can solve at all version.

so, I often use it in macro functions.

for(int _int=0, /* make local variable */ \
    loopOnce=true; loopOnce==true; loopOnce=false)

    for(char _char=0; _char<3; _char++)
    {
        // do anything with
        // _int, _char
    }

Additional 1.

It can also be used to declare local variables and initialize global variables.

float globalFloat;

for(int localInt=0, /* decalre local variable */ \
    _=1;_;_=0)

    for(globalFloat=2.f; localInt<3; localInt++) /* initialize global variable */
    {
        // do.
    }

Additional 2.

Good example : with macro function.

(If best approach can't be used because it is a for-loop-macro)

#define for_two_decl(_decl_1, _decl_2, cond, incr) \
for(_decl_1, _=1;_;_=0)\
    for(_decl_2; (cond); (incr))


    for_two_decl(int i=0, char c=0, i<3, i++)
    {
        // your body with
        // i, c
    }

# If-statement trick

if (A* a=nullptr);
else
    for(...) // a is visible

If you want initialize to 0 or nullptr, you can use this trick.

but I don't recommend this because of hard reading.

and it seems like bug.

Try this, it worked for me.

If you want to change the layou_gravity of an existing view do this:

((FrameLayout.LayoutParams) view.getLayoutParams()).gravity = Gravity.BOTTOM;

Remember to use the right LayoutParams based on the Layout type your view is in. Ex:

LinearLayout.LayoutParams

This means that the compiler defines a backing field at runtime. This is the syntax for auto-implemented properties.

exp(x) = e^x where e= 2.718281(approx)

import numpy as np

ar=np.array([1,2,3])
ar=np.exp(ar)
print ar

outputs:

[ 2.71828183  7.3890561  20.08553692]

The other thing this does is push the function invocation to the bottom of the stack, preventing a stack overflow if you are recursively calling a function. This has the effect of a while loop but lets the JavaScript engine fire other asynchronous timers.

try {
    Import-Module SomeModule
    Write-Host "Module exists"
} 
catch {
    Write-Host "Module does not exist"
}

It should be pointed out that your cmdlet Import-Module has no terminating error, therefore the exception isnt being caught so no matter what your catch statement will never return the new statement you have written.

(https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_try_catch_finally?view=powershell-6

From The Above:

"A terminating error stops a statement from running. If PowerShell does not handle a terminating error in some way, PowerShell also stops running the function or script using the current pipeline. In other languages, such as C#, terminating errors are referred to as exceptions. For more information about errors, see about_Errors."

It should be written as:

Try {
    Import-Module SomeModule -Force -Erroraction stop
    Write-Host "yep"
}
Catch {
    Write-Host "nope"
}

Which returns:

nope

And if you really wanted to be thorough you should add in the other suggested cmdlets Get-Module -ListAvailable -Name and Get-Module -Name to be extra cautious, before running other functions/cmdlets. And if its installed from psgallery or elsewhere you could also run a Find-Module cmdlet to see if there is a new version available.

Gustavo Niemeyer's answer is great. But in Windows, runtime proc is mostly in another dir, like this:

"C:\Users\XXX\AppData\Local\Temp"

If you use relative file path, like "/config/api.yaml", this will use your project path where your code exists.

There is a lot of confusion about IdentityDbContext, a quick search in Stackoverflow and you'll find these questions:
" Why is Asp.Net Identity IdentityDbContext a Black-Box?
How can I change the table names when using Visual Studio 2013 AspNet Identity?
Merge MyDbContext with IdentityDbContext"

To answer to all of these questions we need to understand that IdentityDbContext is just a class inherited from DbContext.
Let's take a look at IdentityDbContext source:

Based on the source code if we want to merge IdentityDbContext with our DbContext we have two options:

First Option:
Create a DbContext which inherits from IdentityDbContext and have access to the classes.

   public class ApplicationDbContext 
    : IdentityDbContext
{
    public ApplicationDbContext()
        : base("DefaultConnection")
    {
    }

    static ApplicationDbContext()
    {
        Database.SetInitializer<ApplicationDbContext>(new ApplicationDbInitializer());
    }

    public static ApplicationDbContext Create()
    {
        return new ApplicationDbContext();
    }

    // Add additional items here as needed
}

Extra Notes:

1) We can also change asp.net Identity default table names with the following solution:

    public class ApplicationDbContext : IdentityDbContext
    {    
        public ApplicationDbContext(): base("DefaultConnection")
        {
        }

        protected override void OnModelCreating(System.Data.Entity.DbModelBuilder modelBuilder)
        {
            base.OnModelCreating(modelBuilder);
            modelBuilder.Entity<IdentityUser>().ToTable("user");
            modelBuilder.Entity<ApplicationUser>().ToTable("user");

            modelBuilder.Entity<IdentityRole>().ToTable("role");
            modelBuilder.Entity<IdentityUserRole>().ToTable("userrole");
            modelBuilder.Entity<IdentityUserClaim>().ToTable("userclaim");
            modelBuilder.Entity<IdentityUserLogin>().ToTable("userlogin");
        }
    }

2) Furthermore we can extend each class and add any property to classes like 'IdentityUser', 'IdentityRole', ...

    public class ApplicationRole : IdentityRole<string, ApplicationUserRole>
{
    public ApplicationRole() 
    {
        this.Id = Guid.NewGuid().ToString();
    }

    public ApplicationRole(string name)
        : this()
    {
        this.Name = name;
    }

    // Add any custom Role properties/code here
}


// Must be expressed in terms of our custom types:
public class ApplicationDbContext 
    : IdentityDbContext<ApplicationUser, ApplicationRole, 
    string, ApplicationUserLogin, ApplicationUserRole, ApplicationUserClaim>
{
    public ApplicationDbContext()
        : base("DefaultConnection")
    {
    }

    static ApplicationDbContext()
    {
        Database.SetInitializer<ApplicationDbContext>(new ApplicationDbInitializer());
    }

    public static ApplicationDbContext Create()
    {
        return new ApplicationDbContext();
    }

    // Add additional items here as needed
}

To save time we can use AspNet Identity 2.0 Extensible Project Template to extend all the classes.

Second Option:(Not recommended)
We actually don't have to inherit from IdentityDbContext if we write all the code ourselves.
So basically we can just inherit from DbContext and implement our customized version of "OnModelCreating(ModelBuilder builder)" from the IdentityDbContext source code

found one interesting cheat sheet here.. http://introcs.cs.princeton.edu/java/11cheatsheet/

If all that you want is to see the disassembly with the INTC call, use objdump -d as someone mentioned but use the -static option when compiling. Otherwise the fopen function is not compiled into the elf and is linked at runtime.

I really like Vitaly Zinchenkos solution since it was short.

Here is an even briefer version in kotlin for a simple fade out

viewToAnimate?.alpha = 1f
viewToAnimate?.animate()
             ?.alpha(0f)
             ?.setDuration(1000)
             ?.setInterpolator(DecelerateInterpolator())
             ?.start()

Assuming you have Files a.txt and b.txt with

cat a.txt
a
b
c
d
1
3
5
cat b.txt
a
1
2
6
7

Keep in mind NR and FNR are awk built-in variables. NR - Gives the total number of records processed. (in this case both in a.txt and b.txt) FNR - Gives the total number of records for each input file (records in either a.txt or b.txt)

awk 'NR==FNR{a[$0];}{if($0 in a)print FILENAME " " NR " " FNR " " $0}' a.txt b.txt
a.txt 1 1 a
a.txt 2 2 b
a.txt 3 3 c
a.txt 4 4 d
a.txt 5 5 1
a.txt 6 6 3
a.txt 7 7 5
b.txt 8 1 a
b.txt 9 2 1

lets Add "next" to skip the first matched with NR==FNR

in b.txt and in a.txt

awk 'NR==FNR{a[$0];next}{if($0 in a)print FILENAME " " NR " " FNR " " $0}' a.txt b.txt
b.txt 8 1 a
b.txt 9 2 1

in b.txt but not in a.txt

 awk 'NR==FNR{a[$0];next}{if(!($0 in a))print FILENAME " " NR " " FNR " " $0}' a.txt b.txt
b.txt 10 3 2
b.txt 11 4 6
b.txt 12 5 7

awk 'NR==FNR{a[$0];next}!($0 in a)' a.txt b.txt

You could try to sort descending "sort LastWriteTime -Descending" and then "select -first 1." Not sure which one is faster

I've just needed a way to get the element that contains a specific text and this is what I came up with.

Use document.getElementsByInnerText() to get multiple elements (multiple elements might have the same exact text), and use document.getElementByInnerText() to get just one element (first match).

Also, you can localize the search by using an element (e.g. someElement.getElementByInnerText()) instead of document.

You might need to tweak it in order to make it cross-browser or satisfy your needs.

I think the code is self-explanatory, so I'll leave it as it is.

To set Conditional Formatting for an ENTIRE ROW based on a single cell you must ANCHOR that single cell's column address with a "$", otherwise Excel will only get the first column correct. Why?

Because Excel is setting your Conditional Format for the SECOND column of your row based on an OFFSET of columns. For the SECOND column, Excel has now moved one column to the RIGHT of your intended rule cell, examined THAT cell, and has correctly formatted column two based on a cell you never intended.

Simply anchor the COLUMN portion of your rule cell's address with "$", and you will be happy

For example: You want any row of your table to highlight red if the last cell of that row does not equal 1.

Select the entire table (but not the headings) "Home" > "Conditional Formatting" > "Manage Rules..." > "New Rule" > "Use a formula to determine which cells to format"

Enter: "=$T3<>1" (no quotes... "T" is the rule cell's column, "3" is its row) Set your formatting Click Apply.

Make sure Excel has not inserted quotes into any part of your formula... if it did, Backspace/Delete them out (no arrow keys please).

Conditional Formatting should be set for the entire table.

A solution without dependencies.

Node

headers.set('Authorization', 'Basic ' + Buffer.from(username + ":" + password).toString('base64'));

Browser

I've used like this

function chatSearchCtrl($scope, $http,$sce) {
 // some more my code

// take this 
data['message'] = $sce.trustAsHtml(data['message']);

$scope.searchresults = data;

and in html I did

<p class="clsPyType clsChatBoxPadding" ng-bind-html="searchresults.message"></p>

thats it I get my <br/> tag rendered

var assemblyPath = Assembly.GetExecutingAssembly().CodeBase;

Douglas Crockford says:

type="text/javascript"

This attribute is optional. Since Netscape 2, the default programming language in all browsers has been JavaScript. In XHTML, this attribute is required and unnecessary. In HTML, it is better to leave it out. The browser knows what to do.

In HTML 4.01 and XHTML 1(.1), the type attribute for <script> elements is required.

You need to configure babel correctly in your project to use export default and export const foo

npm install --save-dev @babel/plugin-proposal-export-default-from

then add below configration in .babelrc

"plugins": [ 
       "@babel/plugin-proposal-export-default-from"
      ]

It really depends on where your JavaScript code is located.

The problem is probably caused by the DOM not being loaded when the line

var systemStatus = document.getElementById("system-status");

is executed. You could try calling this in an onload event, or ideally use a DOM ready type event from a JavaScript framework.

The Good News is:

It's 100% working.

Just add something inside the script tag such as alert('voila!');. The right question you might want to ask perhaps, "Why didn't I see it in the DOM?".

Karl Swedberg has made a nice explanation to visitor's comment in jQuery API site. I don't want to repeat all his words, you can read directly there here (I found it hard to navigate through the comments there).

All of jQuery's insertion methods use a domManip function internally to clean/process elements before and after they are inserted into the DOM. One of the things the domManip function does is pull out any script elements about to be inserted and run them through an "evalScript routine" rather than inject them with the rest of the DOM fragment. It inserts the scripts separately, evaluates them, and then removes them from the DOM.

I believe that one of the reasons jQuery does this is to avoid "Permission Denied" errors that can occur in Internet Explorer when inserting scripts under certain circumstances. It also avoids repeatedly inserting/evaluating the same script (which could potentially cause problems) if it is within a containing element that you are inserting and then moving around the DOM.

The next thing is, I'll summarize what's the bad news by using .append() function to add a script.

And The Bad News is..

You can't debug your code.

I'm not joking, even if you add debugger; keyword between the line you want to set as breakpoint, you'll be end up getting only the call stack of the object without seeing the breakpoint on the source code, (not to mention that this keyword only works in webkit browser, all other major browsers seems to omit this keyword).

If you fully understand what your code does, than this will be a minor drawback. But if you don't, you will end up adding a debugger; keyword all over the place just to find out what's wrong with your (or my) code. Anyway, there's an alternative, don't forget that javascript can natively manipulate HTML DOM.

Workaround.

Use javascript (not jQuery) to manipulate HTML DOM

If you don't want to lose debugging capability, than you can use javascript native HTML DOM manipulation. Consider this example:

var script   = document.createElement("script");
script.type  = "text/javascript";
script.src   = "path/to/your/javascript.js";    // use this for linked script
script.text  = "alert('voila!');"               // use this for inline script
document.body.appendChild(script);

There it is, just like the old days isn't it. And don't forget to clean things up whether in the DOM or in the memory for all object that's referenced and not needed anymore to prevent memory leaks. You can consider this code to clean things up:

document.body.removechild(document.body.lastChild);
delete UnusedReferencedObjects; // replace UnusedReferencedObject with any object you created in the script you load.

The drawback from this workaround is that you may accidentally add a duplicate script, and that's bad. From here you can slightly mimic .append() function by adding an object verification before adding, and removing the script from the DOM right after it was added. Consider this example:

function AddScript(url, object){
    if (object != null){
        // add script
        var script   = document.createElement("script");
        script.type  = "text/javascript";
        script.src   = "path/to/your/javascript.js";
        document.body.appendChild(script);

        // remove from the dom
        document.body.removeChild(document.body.lastChild);
        return true;
    } else {
        return false;
    };
};

function DeleteObject(UnusedReferencedObjects) {
    delete UnusedReferencedObjects;
}

This way, you can add script with debugging capability while safe from script duplicity. This is just a prototype, you can expand for whatever you want it to be. I have been using this approach and quite satisfied with this. Sure enough I will never use jQuery .append() to add a script.

is null can be used to check whether null data is coming from a query as in following example:

 declare @Mem varchar(20),@flag int
select @mem=MemberClub from [dbo].[UserMaster] where UserID=@uid
if(@Mem is null)
begin
    set @flag= 0;
end
else
begin
    set @flag=1;
end
return @flag;

The idea behind reporting progress with the background worker is through sending a 'percent completed' event. You are yourself responsible for determining somehow 'how much' work has been completed. Unfortunately this is often the most difficult part.

In your case, the bulk of the work is database-related. There is to my knowledge no way to get progress information from the DB directly. What you can try to do however, is split up the work dynamically. E.g., if you need to read a lot of data, a naive way to implement this could be.

• Determine how many rows are to be retrieved (SELECT COUNT(*) FROM ...)

• Divide the actual reading in smaller chunks, reporting progress every time one chunk is completed:

  for (int i = 0; i < count; i++)
  {
      bgWorker.ReportProgress((100 * i) / count);
      // ... (read data for step i)
  }
  

On your terminal, try running:

which -a ruby

This will output all the installed Ruby versions (via RVM, or otherwise) on your system in your PATH. If 1.8.7 is your system Ruby version, you can uninstall the system Ruby using:

sudo apt-get purge ruby

Once you have made sure you have Ruby installed via RVM alone, in your login shell you can type:

rvm --default use 2.0.0

You don't need to do this if you have only one Ruby version installed.

If you still face issues with any system Ruby files, try running:

dpkg-query -l '*ruby*'

This will output a bunch of Ruby-related files and packages which are, or were, installed on your system at the system level. Check the status of each to find if any of them is native and is causing issues.

Unless the writer of the executable has specifically provided a way for you to display a list of all the command line switches that it offers, then there is no way of doing this.

As Marcin suggests, the typical switches for displaying all of the options are either /? or /help (some applications might prefer the Unix-style syntax, -? and -help, respectively). But those are just a common convention.

If those don't work, you're out of luck. You'll need to check the documentation for the application, or perhaps try decompiling the executable (if you know what you're looking for).

To make changes to sudo from putty/bash:

• Type visudo and press enter.
• Navigate to the place you wish to edit using the up and down arrow keys.
• Press insert to go into editing mode.
• Make your changes - for example: user ALL=(ALL) ALL.
• Note - it matters whether you use tabs or spaces when making changes.
• Once your changes are done press esc to exit editing mode.
• Now type :wq to save and press enter.
• You should now be back at bash.
• Now you can press ctrl + D to exit the session if you wish.

I tried the answer but it didn't worked for me. This is what i ended up doing:

Create a new controller DefaultController. In index action, i wrote one line redirect:

return Redirect("~/Default.aspx")

In RouteConfig.cs, change controller="Default" for the route.

 routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Default", action = "Index", id = UrlParameter.Optional }
        );

Make sure you specify pass header=None and add usecols=[3,6] for the 4th and 7th columns.

You can find your sample code completely here: http://www.java2s.com/Code/Java/Hibernate/OneToManyMappingbasedonSet.htm

Have a look and check the differences. specially the even_id in :

<set name="attendees" cascade="all">
    <key column="event_id"/>
    <one-to-many class="Attendee"/>
</set> 

What you want to do is get the absolute path of the script (available via ${BASH_SOURCE[0]}) and then use this to get the parent directory and cd to it at the beginning of the script.

#!/bin/bash
parent_path=$( cd "$(dirname "${BASH_SOURCE[0]}")" ; pwd -P )

cd "$parent_path"
cat ../some.text

This will make your shell script work independent of where you invoke it from. Each time you run it, it will be as if you were running ./cat.sh inside dir.

Note that this script only works if you're invoking the script directly (i.e. not via a symlink), otherwise the finding the current location of the script gets a little more tricky)

Try this first:

git checkout master

(If you're on a different branch than master, use the branch name there instead.)

If that doesn't work, try...

For a single file:

git checkout HEAD /path/to/file

For the entire repository working copy:

git reset --hard HEAD

And if that doesn't work, then you can look in the reflog to find your old head SHA and reset to that:

git reflog
git reset --hard <sha from reflog>

HEAD is a name that always points to the latest commit in your current branch.

Simple JavaScript, string to float:

var it_price = chief_double($("#ContentPlaceHolder1_txt_it_price").val());

function chief_double(num){
    var n = parseFloat(num);
    if (isNaN(n)) {
        return "0";
    }
    else {
        return parseFloat(num);
    }
}

doAnswer and thenReturn do the same thing if:

1. You are using Mock, not Spy
2. The method you're stubbing is returning a value, not a void method.

Let's mock this BookService

public interface BookService {
    String getAuthor();
    void queryBookTitle(BookServiceCallback callback);
}

You can stub getAuthor() using doAnswer and thenReturn.

BookService service = mock(BookService.class);
when(service.getAuthor()).thenReturn("Joshua");
// or..
doAnswer(new Answer() {
    @Override
    public Object answer(InvocationOnMock invocation) throws Throwable {
        return "Joshua";
    }
}).when(service).getAuthor();

Note that when using doAnswer, you can't pass a method on when.

// Will throw UnfinishedStubbingException
doAnswer(invocation -> "Joshua").when(service.getAuthor());

So, when would you use doAnswer instead of thenReturn? I can think of two use cases:

1. When you want to "stub" void method.

Using doAnswer you can do some additionals actions upon method invocation. For example, trigger a callback on queryBookTitle.

BookServiceCallback callback = new BookServiceCallback() {
    @Override
    public void onSuccess(String bookTitle) {
        assertEquals("Effective Java", bookTitle);
    }
};
doAnswer(new Answer() {
    @Override
    public Object answer(InvocationOnMock invocation) throws Throwable {
        BookServiceCallback callback = (BookServiceCallback) invocation.getArguments()[0];
        callback.onSuccess("Effective Java");
        // return null because queryBookTitle is void
        return null;
    }
}).when(service).queryBookTitle(callback);
service.queryBookTitle(callback);

2. When you are using Spy instead of Mock

When using when-thenReturn on Spy Mockito will call real method and then stub your answer. This can cause a problem if you don't want to call real method, like in this sample:

List list = new LinkedList();
List spy = spy(list);
// Will throw java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
when(spy.get(0)).thenReturn("java");
assertEquals("java", spy.get(0));

Using doAnswer we can stub it safely.

List list = new LinkedList();
List spy = spy(list);
doAnswer(invocation -> "java").when(spy).get(0);
assertEquals("java", spy.get(0));

Actually, if you don't want to do additional actions upon method invocation, you can just use doReturn.

List list = new LinkedList();
List spy = spy(list);
doReturn("java").when(spy).get(0);
assertEquals("java", spy.get(0));

I am new to JavaScript development and ReactJS. I was unable to find an answer that works for me, until figuring it out by viewing the react-scripts code. Using ReactJS 15.4.1+ using react-scripts you can start with a custom host and/or port by using environment variables:

HOST='0.0.0.0' PORT=8080 npm start

Hopefully this helps newcomers like me.

A possibility is using flash cookies:

• Ubiquitous availability (95 percent of visitors will probably have flash)
• You can store more data per cookie (up to 100 KB)
• Shared across browsers, so more likely to uniquely identify a machine
• Clearing the browser cookies does not remove the flash cookies.

You'll need to build a small (hidden) flash movie to read and write them.

Whatever route you pick, make sure your users opt IN to being tracked, otherwise you're invading their privacy and become one of the bad guys.

Use sprintf.

int sprintf ( char * str, const char * format, ... );

Write formatted data to string Composes a string with the same text that would be printed if format was used on printf, but instead of being printed, the content is stored as a C string in the buffer pointed by str.

The size of the buffer should be large enough to contain the entire resulting string (see snprintf for a safer version).

A terminating null character is automatically appended after the content.

After the format parameter, the function expects at least as many additional arguments as needed for format.

Parameters:

str

Pointer to a buffer where the resulting C-string is stored. The buffer should be large enough to contain the resulting string.

format

C string that contains a format string that follows the same specifications as format in printf (see printf for details).

... (additional arguments)

Depending on the format string, the function may expect a sequence of additional arguments, each containing a value to be used to replace a format specifier in the format string (or a pointer to a storage location, for n). There should be at least as many of these arguments as the number of values specified in the format specifiers. Additional arguments are ignored by the function.

Example:

// Allocates storage
char *hello_world = (char*)malloc(13 * sizeof(char));
// Prints "Hello world!" on hello_world
sprintf(hello_world, "%s %s!", "Hello", "world");

I had the same issue today using primefaces (primeng) and angular 7. Add the following to your style.css

p-button {
   -webkit-appearance: none !important;
}

i am also using a bit of bootstrap which has a reboot.css, that overrides it with (thats why i had to add !important)

button {
  -webkit-appearance: button;

}

If you print(type(Num.getone)) you will get <class 'function'>.

It is just a plain function, and be called as usual (with no arguments):

Num.getone() # returns 1  as expected

but if you print print(type(myObj.getone)) you will get <class 'method'>.

So when you call getone() from an instance of the class, Python automatically "transforms" the function defined in a class into a method.

An instance method requires the first argument to be the instance object. You can think myObj.getone() as syntactic sugar for

Num.getone(myObj) # this explains the Error 'getone()' takes no arguments (1 given).

For example:

class Num:
    def __init__(self,num):
        self.n = num
    def getid(self):
        return id(self)

myObj=Num(3)

Now if you

print(id(myObj) == myObj.getid())    
# returns True

As you can see self and myObj are the same object

Put double quotes around the path that has spaces like this:

It seem like your Resort method doesn't declare a compareTo method. This method typically belongs to the Comparable interface. Make sure your class implements it.

Additionally, the compareTo method is typically implemented as accepting an argument of the same type as the object the method gets invoked on. As such, you shouldn't be passing a String argument, but rather a Resort.

Alternatively, you can compare the names of the resorts. For example

if (resortList[mid].getResortName().compareTo(resortName)>0)

First way is

function function1()
{
  var variable1=12;
  function2(variable1);
}

function function2(val)
{
  var variableOfFunction1 = val;

// Then you will have to use this function for the variable1 so it doesn't really help much unless that's what you want to do. }

Second way is

var globalVariable;
function function1()

  globalVariable=12;
  function2();
}

function function2()

I faced same issue. I deleted post-build events and it started working. Some times when we add some SQL components it may add post build commands also.

From Sql Server 2008 you have "date" format.

So you can use

SELECT * FROM LOGS WHERE CONVERT(date,[CHECK_IN]) BETWEEN '2013-10-18' AND '2013-10-18'

https://docs.microsoft.com/en-us/sql/t-sql/data-types/date-transact-sql

1) Launch Ubuntu Instance on EC2.
2) Open SSH Port in instance security.
3) Do SSH to instance.
4) Execute:

sudo apt-get update    sudo apt-get upgrade

5) Because you will be connecting from Windows Remote Desktop, edit the sshd_config file on your Linux instance to allow password authentication.

sudo vim /etc/ssh/sshd_config

6) Change PasswordAuthentication to yes from no, then save and exit.
7) Restart the SSH daemon to make this change take effect.

sudo /etc/init.d/ssh restart

8) Temporarily gain root privileges and change the password for the ubuntu user to a complex password to enhance security. Press the Enter key after typing the command passwd ubuntu, and you will be prompted to enter the new password twice.

sudo –i
passwd ubuntu

9) Switch back to the ubuntu user account and cd to the ubuntu home directory.

su ubuntu
cd

10) Install Ubuntu desktop functionality on your Linux instance, the last command can take up to 15 minutes to complete.

export DEBIAN_FRONTEND=noninteractive
sudo -E apt-get update
sudo -E apt-get install -y ubuntu-desktop

11) Install xrdp

sudo apt-get install xfce4
sudo apt-get install xfce4 xfce4-goodies

12) Make xfce4 the default window manager for RDP connections.

echo xfce4-session > ~/.xsession

13) Copy .xsession to the /etc/skel folder so that xfce4 is set as the default window manager for any new user accounts that are created.

sudo cp /home/ubuntu/.xsession /etc/skel

14) Open the xrdp.ini file to allow changing of the host port you will connect to.

sudo vim /etc/xrdp/xrdp.ini

(xrdp is not installed till now. First Install the xrdp with sudo apt-get install xrdp then edit the above mentioned file)

15) Look for the section [xrdp1] and change the following text (then save and exit [:wq]).

port=-1
- to -
port=ask-1

16) Restart xrdp.

sudo service xrdp restart

17) On Windows, open the Remote Desktop Connection client, paste the fully qualified name of your Amazon EC2 instance for the Computer, and then click Connect.

18) When prompted to Login to xrdp, ensure that the sesman-Xvnc module is selected, and enter the username ubuntu with the new password that you created in step 8. When you start a session, the port number is -1.

19) When the system connects, several status messages are displayed on the Connection Log screen. Pay close attention to these status messages and make note of the VNC port number displayed. If you want to return to a session later, specify this number in the port field of the xrdp login dialog box.

You could do something like this

HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://localhost:6740/api/Membership/exist");

req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";         
req.ContentLength = 6;

StreamWriter streamOut = new StreamWriter(req.GetRequestStream(), System.Text.Encoding.ASCII);
streamOut.Write(strRequest);
streamOut.Close();
StreamReader streamIn = new StreamReader(req.GetResponse().GetResponseStream());
string strResponse = streamIn.ReadToEnd();
streamIn.Close();

And then strReponse should contain the values returned by your webservice

The Python documentation does explain it.

Tuples and lists are compared lexicographically using comparison of corresponding elements. This means that to compare equal, each element must compare equal and the two sequences must be of the same type and have the same length.

Select * from table_name where date(datetime)

All of these answers are simple and good. However, I always like to add an interactive mode to these scripts so that I can find false positives.

if [[ -n $inInteractiveMode ]]
then
  echo -e -n "$oldFileName => $newFileName\nDo you want to do this change? [Y/n]: "
  read run

  [[ -z $run || "$run" == "y" || "$run" == "Y" ]] && mv "$oldFileName" "$newFileName"
fi

Or make interactive mode the default and add a force flag (-f | --force) for automated scripts or if you're feeling daring. And this doesn't slow you down too much: the default response is "yes, I do want to rename" so you can just hit the enter key at each prompt (because of the ``-z $run\ test.

I think the biggest argument for functional programming languages to become the "next big thing" is that in the future multi-core processors will be the norm. Programmers will have to take advantage of that, and functional programming offers really wonderful possibilities for building top of the line concurrent software.

P.S. When I was in college at Boston University ('98-'02) we spent a semester learning Scheme which is a close cousin of LISP. When we first started learning it, I wanted to rip my hair out. By the end of the course it was very natural.

Keeping in mind the points made in @John Woo's comment/link above, this is how I typically would handle it:

SELECT t1.ID, t1.Name 
FROM   Table1 t1
WHERE  NOT EXISTS (
    SELECT TOP 1 NULL
    FROM Table2 t2
    WHERE t1.ID = t2.ID
)

You are trying to set "++" on a jQuery element!

YOu could declare a js variable

var counter = 0;

and in jQuery code do:

$("#counter").html(counter++);

Dictionary<int,string> comboSource = new Dictionary<int,string>();
comboSource.Add(1, "Sunday");
comboSource.Add(2, "Monday");

Aftr adding values to Dictionary, use this as combobox datasource:

comboBox1.DataSource = new BindingSource(comboSource, null);
comboBox1.DisplayMember = "Value";
comboBox1.ValueMember = "Key";

Here are a few options for changing text / label sizes

library(ggplot2)

# Example data using mtcars

a <- aggregate(mpg ~ vs + am , mtcars, function(i) round(mean(i)))

p <- ggplot(mtcars, aes(factor(vs), y=mpg, fill=factor(am))) + 
            geom_bar(stat="identity",position="dodge") + 
            geom_text(data = a, aes(label = mpg), 
                            position = position_dodge(width=0.9),  size=20)

The size in the geom_text changes the size of the geom_text labels.

p <- p + theme(axis.text = element_text(size = 15)) # changes axis labels

p <- p + theme(axis.title = element_text(size = 25)) # change axis titles

p <- p + theme(text = element_text(size = 10)) # this will change all text size 
                                                             # (except geom_text)

For this And why size of 10 in geom_text() is different from that in theme(text=element_text()) ?

Yes, they are different. I did a quick manual check and they appear to be in the ratio of ~ (14/5) for geom_text sizes to theme sizes.

So a horrible fix for uniform sizes is to scale by this ratio

geom.text.size = 7
theme.size = (14/5) * geom.text.size

ggplot(mtcars, aes(factor(vs), y=mpg, fill=factor(am))) + 
  geom_bar(stat="identity",position="dodge") + 
  geom_text(data = a, aes(label = mpg), 
            position = position_dodge(width=0.9),  size=geom.text.size) + 
  theme(axis.text = element_text(size = theme.size, colour="black")) 

This of course doesn't explain why? and is a pita (and i assume there is a more sensible way to do this)

Drop root privileges after you bind to port 80 (or 443).

This allows port 80/443 to remain protected, while still preventing you from serving requests as root:

function drop_root() {
    process.setgid('nobody');
    process.setuid('nobody');
}

A full working example using the above function:

var process = require('process');
var http = require('http');
var server = http.createServer(function(req, res) {
    res.write("Success!");
    res.end();
});

server.listen(80, null, null, function() {
    console.log('User ID:',process.getuid()+', Group ID:',process.getgid());
    drop_root();
    console.log('User ID:',process.getuid()+', Group ID:',process.getgid());
});

See more details at this full reference.

This is what I used when I stumbled upon this problem.

def order(list_item, i): # reorder at index i
    order_at = list_item.index(i)
    ordered_list = list_item[order_at:] + list_item[:order_at]
    return ordered_list

EX: for the the lowercase letters

order(string.ascii_lowercase, 'h'):
>>> 'hijklmnopqrstuvwxyzabcdefg'

It simply just shifts the list to a specified index

You can get a set of commits by using pick-axe.

git log -S'the line from your file' -- path/to/your/file.txt

This will give you all of the commits that affected that text in that file. If the file was renamed at some point, you can add --follow-parent.

If you would like to inspect the commits at each of these edits, you can pipe that result to git show:

git log ... | xargs -n 1 git show

While I enjoy using dplyr for interactive use, I find it extraordinarily tricky to do this using dplyr because you have to go through hoops to use lazyeval::interp(), setNames, etc. workarounds.

Here is a simpler version using base R, in which it seems more intuitive, to me at least, to put the loop inside the function, and which extends @MrFlicks's solution.

multipetal <- function(df, n) {
   for (i in 1:n){
      varname <- paste("petal", i , sep=".")
      df[[varname]] <- with(df, Petal.Width * i)
   }
   df
}
multipetal(iris, 3) 

this.setState({ [`${event.target.id}`]: event.target.value}, () => {
      console.log("State updated: ", JSON.stringify(this.state[event.target.id]));
    });

Please mind the quote character.

Oftentimes you see the suggestion use use keyword arguments, with default values, instead. Look into that.

This is what I do, just add \n and use encodeURIComponent

Example

var emailBody = "1st line.\n 2nd line \n 3rd line";

emailBody = encodeURIComponent(emailBody);

href = "mailto:[email protected]?body=" + emailBody;

Check encodeURIComponent docs

As Pedro said, you have an issue with the debugger preventing the message pump if you are stepping through code.

But if you are performing a long running operation on the UI thread, then call Application.DoEvents() which explicitly pumps the message queue and then returns control to your current method.

However if you are doing this I would recommend at looking at your design so that you can perform processing off the UI thread so that your UI remains nice and snappy.

Marco's answer above is correct, but just to expand on the question of "under what context"...

frame - this is the property you most often use for normal iPhone applications. most controls will be laid out relative to the "containing" control so the frame.origin will directly correspond to where the control needs to display, and frame.size will determine how big to make the control.

center - this is the property you will likely focus on for sprite based games and animations where movement or scaling may occur. By default animation and rotation will be based on the center of the UIView. It rarely makes sense to try and manage such objects by the frame property.

bounds - this property is not a positioning property, but defines the drawable area of the UIView "relative" to the frame. By default this property is usually (0, 0, width, height). Changing this property will allow you to draw outside of the frame or restrict drawing to a smaller area within the frame. A good discussion of this can be found at the link below. It is uncommon for this property to be manipulated unless there is specific need to adjust the drawing region. The only exception is that most programs will use the [[UIScreen mainScreen] bounds] on startup to determine the visible area for the application and setup their initial UIView's frame accordingly.

Why is there an frame rectangle and an bounds rectangle in an UIView?

Hopefully this helps clarify the circumstances where each property might get used.

Assuming that you have JAXB installed Go to the following directory C:\Program Files\jaxb\bin open command window here

> xjc -wsdl http://localhost/mywsdl/MyDWsdl.wsdl C:\Users\myname\Desktop

C:\Users\myname\Desktop is the ouput folder you can change that to your preference

http://localhost/mywsdl/MyDWsdl.wsdl is the link to the WSDL

the answers above were confusing to me. Here is what i did:

• File ->new Image Asset

• the first field "Asset type" must be launcher icons. browse to the file you want as icon, select it and android studio will show you in the same window what it will look like under different resolutions.

• choose a different name for it, click next. Now the icon set for all those hdpi, xhdpi, mdpi will be in corresponding mipmap folders

• finally, most importantly go to your manifest file and change "android:icon" to the name of your new icon image.

<input type="text" name="Name" value="Name" onfocus="this.value = ''" onblur=" if(this.value = '') { value = 'Name'}" />

You should use absolute directory path when applying find instruction with regular expression. In your example, the

find . -regex "[a-f0-9\-]\{36\}\.jpg"

should be changed into

find . -regex "./[a-f0-9\-]\{36\}\.jpg"

In most Linux systems, some disciplines in regular expression cannot be recognized by that system, so you have to explicitly point out -regexty like

find . -regextype posix-extended -regex "[a-f0-9\-]\{36\}\.jpg"

I would suggest you to test it firstly: copy this train.csv to the same directory as this jupyter script in and then change the path to train.csv to test whether this can be loaded successfully.

If yes, that means the previous path input is a problem

If not, that means the file it self denied your access to it, or its real filename can be something else like: train.csv.<hidden extension>

import java.io.File;
public class Test {
    public static void main( String [] args ) {
        File actual = new File(".");
        for( File f : actual.listFiles()){
            System.out.println( f.getName() );
        }
    }
}

It displays indistinctly files and folders.

See the methods in File class to order them or avoid directory print etc.

http://java.sun.com/javase/6/docs/api/java/io/File.html

By this you can get any index in *ngFor loop in ANGULAR ...

<ul>
  <li *ngFor="let object of myArray; let i = index; let first = first ;let last = last;">
    <div *ngIf="first">
       // write your code...
    </div>

    <div *ngIf="last">
       // write your code...
    </div>
  </li>
</ul>

We can use these alias in *ngFor

• index : number : let i = index to get all index of object.
• first : boolean : let first = first to get first index of object.
• last : boolean : let last = last to get last index of object.
• odd : boolean : let odd = odd to get odd index of object.
• even : boolean : let even = even to get even index of object.

you can use UUEncoding

The string in quotes after "[submodule" doesn't matter. You can change it to "foobar" if you want. It's used to find the matching entry in ".git/config".

Therefore, if you make the change before you run "git submodule init", it'll work fine. If you make the change (or pick up the change through a merge), you'll need to either manually edit .git/config or run "git submodule init" again. If you do the latter, you'll be left with a harmless "stranded" entry with the old name in .git/config.

A good idea could be to encapsulate everything inside groups, no matter if need to identify them or not. That way you can use them in your replacement string. For example:

var pattern = @"(-)(\d+)(-)";
var replaced = Regex.Replace(text, pattern, "$1AA$3"); 

or using a MatchEvaluator:

var replaced = Regex.Replace(text, pattern, m => m.Groups[1].Value + "AA" + m.Groups[3].Value);

Another way, slightly messy, could be using a lookbehind/lookahead:

(?<=-)(\d+)(?=-)

sed -i '/pattern/d' file

Use 'd' to delete a line. This works at least with GNU-Sed.

If your Sed doesn't have the option, to change a file in place, maybe you can use an intermediate file, to store the modification:

sed '/pattern/d' file > tmpfile && mv tmpfile file

Writing directly to the source usually doesn't work: sed '/pattern/d' file > file so make a copy before trying out, if you doubt it.

For multiple lines

xposition = [0.3, 0.4, 0.45]
for xc in xposition:
    plt.axvline(x=xc, color='k', linestyle='--')

This answer is much the same as others except I prefer not to use as many class names. But that's just personal preference. You could argue that using class names on each div is more transparent as declares up front the purpose of the nested divs.

<div id="MyDiv" class="proportional">
  <div>
    <div>
      <p>Content</p>
    </div>
  </div>
</div>

Here's the generic CSS:

.proportional { position:relative; }
.proportional > div > div { position:absolute; top:0px; bottom:0px; left:0px; right:0px; }

Then target the first inner div to set width and height (padding-top):

#MyDiv > div { width:200px; padding-top:50%; }

This is a bit stupid maybe but the error message I got was Permission denied and it sent me spiralling down in a very wrong direction to attempt to solve it. (Here for example)

I haven't even added any bash script myself, I think one is added by nodejs image which I use.

FROM node:14.9.0

I was wrongly running to expose/connect the port on my local:

docker run -p 80:80 [name] . # this is wrong!

which gives

/usr/local/bin/docker-entrypoint.sh: 8: exec: .: Permission denied

But you shouldn't even have a dot in the end, it was added to documentation of another projects docker image by misstake. You should simply run:

docker run -p 80:80 [name]

I like Docker a lot but it's sad it has so many gotchas like this and not always very clear error messages...

import org.apache.commons.lang3.BooleanUtils;
boolean x = true;   
int y= BooleanUtils.toInteger(x);

If your html is styled with css, you can probably link different style sheets for different sizes.

Modulus, in modular arithmetic as you're referring, is the value left over or remaining value after arithmetic division. This is commonly known as remainder. % is formally the remainder operator in C / C++. Example:

7 % 3 = 1  // dividend % divisor = remainder

What's left for discussion is how to treat negative inputs to this % operation. Modern C and C++ produce a signed remainder value for this operation where the sign of the result always matches the dividend input without regard to the sign of the divisor input.

What is the return type of the round() method in the snippet?

If this is the Math.round() method, it returns a Long when the input param is Double.

So, you will have to cast the return value:

int a = (int) Math.round(doubleVar);

Yes, you are right. It's impossible with HTML. User will be able to pick whatever file he/she wants.

You could write a piece of JavaScript code to avoid submitting a file based on its extension. But keep in mind that this by no means will prevent a malicious user to submit any file he/she really wants to.

Something like:

function beforeSubmit()
{
    var fname = document.getElementById("ifile").value;
    // check if fname has the desired extension
    if (fname hasDesiredExtension) {
        return true;
    } else {
        return false;
    }
}

HTML code:

<form method="post" onsubmit="return beforeSubmit();">
    <input type="file" id="ifile" name="ifile"/>
</form>

Put the modal and javascript into the partial view. Then call the partial view in your page. This will handle form submission too.

Partial View

<div id="confirmDialog" class="modal fade" data-backdrop="false">
 <div class="modal-dialog" data-backdrop="false">
    <div class="modal-content">
        <div class="modal-header">
            <h4 class="modal-title">Missing Service Order</h4>
        </div>
        <div class="modal-body">
            <p>You have not entered a Service Order. Do you want to continue?</p>
        </div>
        <div class="modal-footer">
            <input id="btnSubmit" type="submit" class="btn btn-primary" 
              value="Submit" href="javascript:" 
               onClick="document.getElementById('Coordinate').submit()" />
            <button type="button" class="btn btn-default" data- 
                                               dismiss="modal">Cancel</button>
        </div>
    </div>
  </div>
</div>

Javascript

  <script type="text/javascript" language="javascript">
$(document).ready(function () {
    $("#Coordinate").on('submit',
        function (e) {
            if ($("#ServiceOrder").val() == '') {
                e.preventDefault();
                $('#confirmDialog').modal('show');
               }
            });
    });
</script>

Then just call your partial inside the form of your page.

Create.cshtml

 @using (Html.BeginForm("Edit","Home",FormMethod.Post, new {id ="Coordinate"}))
 {
     //Form Code

     @Html.Partial("ConfirmDialog") 
 }

The following selects all descendant elements and disables them:

$("#dcacl").find("*").prop("disabled", true);

But it only really makes sense to disable certain element types: inputs, buttons, etc., so you want a more specific selector:

$("#dcac1").find(":input").prop("disabled",true);
// noting that ":input" gives you the equivalent of
$("#dcac1").find("input,select,textarea,button").prop("disabled",true);

To re-enable you just set "disabled" to false.

I want to Disable them at loading the page and then by a click i can enable them

OK, so put the above code in a document ready handler, and setup an appropriate click handler:

$(document).ready(function() {
    var $dcac1kids = $("#dcac1").find(":input");
    $dcac1kids.prop("disabled",true);

    // not sure what you want to click on to re-enable
    $("selector for whatever you want to click").one("click",function() {
       $dcac1kids.prop("disabled",false);
    }
}

I've cached the results of the selector on the assumption that you're not adding more elements to the div between the page load and the click. And I've attached the click handler with .one() since you haven't specified a requirement to re-disable the elements so presumably the event only needs to be handled once. Of course you can change the .one() to .click() if appropriate.

By the rational of making everything multiplication I add the entry at the end of the list

    clc; clear all;
    V = rand(1024*1024*32,1);
    N = 10;
    tic; for i=1:N, V1 = V/norm(V);         end; toc % 4.5 s
    tic; for i=1:N, V2 = V/sqrt(sum(V.*V)); end; toc % 7.5 s
    tic; for i=1:N, V3 = V/sqrt(V'*V);      end; toc % 4.9 s
    tic; for i=1:N, V4 = V/sqrt(sum(V.^2)); end; toc % 6.8 s
    tic; for i=1:N, V1 = V/norm(V);         end; toc % 4.7 s
    tic; for i=1:N, d = 1/norm(V); V1 = V*d;end; toc % 4.9 s
    tic; for i=1:N, d = norm(V)^-1; V1 = V*d;end;toc % 4.4 s

The correct syntax is:

FOR EACH ROW SET NEW.bname = CONCAT( UCASE( LEFT( NEW.bname, 1 ) )
                                   , LCASE( SUBSTRING( NEW.bname, 2 ) ) )

Also, if, like me, you add controls directly in XAML (not using the editor), you might get frustrated that it won't stretch to the available height, even after setting those two properties.

To make the TextBox stretch, set the Height="Auto".

UPDATE:

In retrospect, I think this must have been necessary thanks to a default style for TextBoxes specifying the height to some standard for the application somewhere in the App resources. It may be worthwhile checking this if this helped you.

You can also encode bytes to Base64. How to get this from a stream see here: How to convert an Stream into a byte[] in C#?

Or I think it should be also possible to use the .ToString() method and encode this.

For those of you who came here looking for how to remove an object from a JSON array based on object value:

let users = [{"name": "Ben"},{"name": "Tim"},{"name": "Harry"}];

 for (let [i, user] of users.entries()) {
    if (user.name == "Tim") {
        users.splice(i, 1);
    }
 }

User Tim is now removed from JSON array users.

Use java.utils.Arrays:

public int getTheNumber(int[] factors) {
    int[] f = (int[])factors.clone();
    Arrays.sort(f);
    return f[0]*f[(f.length-1];
}

Or if you want to be efficient avoid all the object allocation just actually do the work:

public static int getTheNumber(int[] array) {
    if (array.length == 0)
        throw new IllegalArgumentException();
    int min = array[0];
    int max = array[0];
    for (int i = 1; i< array.length;++i) {
        int v = array[i];
        if (v < min) {
            min = v;
        } else if (v > max) {
            max = v;
        }
    }
    return min * max;
}

This worked for me:

string Connection = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source="
    + HttpContext.Current.Server.MapPath("\\myPath\\myFile.db")
    + ";Extended Properties=\"Excel 12.0 Xml;HDR=YES\"";

I'm querying an XLSX file so don't worry about any of the other stuff in the connection string but the Data Source.

So my answer is:

HttpContext.Current.Server.MapPath("\\myPath\\myFile.db")

Set minDate to current date in jQuery Datepicker :

$("input.DateFrom").datepicker({
    minDate: new Date()
});

There are two answers above up-to-now and they are both long (and tl;dr too short IMHO), so I write summary from my experience starting to use new java.time library (applicable as noted in other answers to Java version 8+). ISO 8601 sets standard way to write dates: YYYY-MM-DD so the format of date-time is only as below (could be 0, 3, 6 or 9 digits for milliseconds) and no formatting string necessary:

import java.time.Instant;
public static void main(String[] args) {
    String date="2010-10-02T12:23:23Z";
    try {
        Instant myDate = Instant.parse(date);
    } catch (ParseException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

I did not need it, but as getting year is in code from the question, then:
it is trickier, cannot be done from Instant directly, can be done via Calendar in way of questions Get integer value of the current year in Java and Converting java.time to Calendar but IMHO as format is fixed substring is more simple to use:

myDate.toString().substring(0,4);

The accepted answer will give a false positive if the input is a number plus text, because "stol" will convert the firsts digits and ignore the rest.

I like the following version the most, since it's a nice one-liner that doesn't need to define a function and you can just copy and paste wherever you need it.

#include <string>

...

std::string s;

bool has_only_digits = (s.find_first_not_of( "0123456789" ) == std::string::npos);

EDIT: if you like this implementation but you do want to use it as a function, then this should do:

bool has_only_digits(const string s){
  return s.find_first_not_of( "0123456789" ) == string::npos;
}

You can use SimpleDateFormat to do it. You just have to know 2 things.

1. All dates are internally represented in UTC
2. .getTime() returns the number of milliseconds since 1970-01-01 00:00:00 UTC.

package se.wederbrand.milliseconds;

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

public class Main {        
    public static void main(String[] args) throws Exception {
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
        sdf.setTimeZone(TimeZone.getTimeZone("UTC"));

        String inputString = "00:01:30.500";

        Date date = sdf.parse("1970-01-01 " + inputString);
        System.out.println("in milliseconds: " + date.getTime());        
    }
}

On your list view, use setOnItemClickListener

You can use Array#filter function and additional array for storing sorted values;

var recordsSorted = []

ids.forEach(function(e) {
    recordsSorted.push(records.filter(function(o) {
        return o.empid === e;
    }));
});

console.log(recordsSorted);

Result:

[ [ { empid: 1, fname: 'X', lname: 'Y' } ],
  [ { empid: 4, fname: 'C', lname: 'Y' } ],
  [ { empid: 5, fname: 'C', lname: 'Y' } ] ]

Try this. It works on the same database in which the code resides. Just call the CompactDB() function shown below. Make sure that after you add the function, you click the Save button in the VBA Editor window prior to running for the first time. I only tested it in Access 2010. Ba-da-bing, ba-da-boom.

Public Function CompactDB()

    Dim strWindowTitle As String

    On Error GoTo err_Handler

    strWindowTitle = Application.Name & " - " & Left(Application.CurrentProject.Name, Len(Application.CurrentProject.Name) - 4)
    strTempDir = Environ("Temp")
    strScriptPath = strTempDir & "\compact.vbs"
    strCmd = "wscript " & """" & strScriptPath & """"

    Open strScriptPath For Output As #1
    Print #1, "Set WshShell = WScript.CreateObject(""WScript.Shell"")"
    Print #1, "WScript.Sleep 1000"
    Print #1, "WshShell.AppActivate " & """" & strWindowTitle & """"
    Print #1, "WScript.Sleep 500"
    Print #1, "WshShell.SendKeys ""%yc"""
    Close #1

    Shell strCmd, vbHide
    Exit Function

    err_Handler:

use java.nio.channels.FileLock in conjunction with java.nio.channels.FileChannel

I wonder why no one was able to get what the question actually asked. It stated What is the command within the SQLite shell tool to specify a database file?

A sqlite db is on my hard disk E:\ABCD\efg\mydb.db. How do I access it with sqlite3 command line interface? .open E:\ABCD\efg\mydb.db does not work. This is what question asked.

I found the best way to do the work is

• copy-paste all your db files in 1 directory (say E:\ABCD\efg\mydbs)
• switch to that directory in your command line
• now open sqlite3 and then .open mydb.db

This way you can do the join operation on different tables belonging to different databases as well.

You can use below code snippet

import shlex
import subprocess
import json

def call_curl(curl):
    args = shlex.split(curl)
    process = subprocess.Popen(args, shell=False, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
    stdout, stderr = process.communicate()
    return json.loads(stdout.decode('utf-8'))


if __name__ == '__main__':
    curl = '''curl - X
    POST - d
    '{"nw_src": "10.0.0.1/32", "nw_dst": "10.0.0.2/32", "nw_proto": "ICMP", "actions": "ALLOW", "priority": "10"}'
    http: // localhost: 8080 / firewall / rules / 0000000000000001 '''
    output = call_curl(curl)
    print(output)

from datetime import timedelta    
datetime.datetime.now() - datetime.timedelta(0, 900)

Actually 900 is in seconds. Which is equal to 15 minutes. `15*60 = 900`

If you need to have jquery use !important for more than one item, this is how you would do it.

e.g. set an img tags max-width and max-height to 500px each

$('img').css('cssText', "max-width: 500px !important;' + "max-height: 500px !important;');

Make sure you have added your device - https://developer.apple.com/account/ios/device/create

Go into iTunes and click on the serial number and it'll change to the UDID - then right click to Copy the UDID and register it as your device.

You can then add that device to your provisioning profile.

What I did was compare the iframe scrollWidth until it changed size while i incrementally set the IFrame Height. And it worked fine for me. You can adjust the increment to whatever is desired.

   <script type="text/javascript">
    function AdjustIFrame(id) {
        var frame = document.getElementById(id);
        var maxW = frame.scrollWidth;
        var minW = maxW;
        var FrameH = 100; //IFrame starting height
        frame.style.height = FrameH + "px"

        while (minW == maxW) {
            FrameH = FrameH + 100; //Increment
            frame.style.height = FrameH + "px";
            minW = frame.scrollWidth;
        }
    }

   </script>


<iframe id="RefFrame" onload="AdjustIFrame('RefFrame');" class="RefFrame"
    src="http://www.YourUrl.com"></iframe>

Check if any of your .php files which printing some text, also is correctly encoding in utf-8.

I know this was answered a while ago but just chiming with a simple solution here that I am surprised wasn't mentioned.

=RIGHT("0000" & A1, 4)

Whenever I need to pad I use something like the above. Personally I find it the simplest solution and easier to read.

You can achieve customized radio buttons in two pure CSS ways

1. Via removing standard appearance using CSS appearance and applying custom appearance. Unfortunately this was doesn't work in IE for Desktop (but works in IE for Windows Phone). Demo:

   _x000D_

   _x000D_

   input[type="radio"] {
     /* remove standard background appearance */
     -webkit-appearance: none;
     -moz-appearance: none;
     appearance: none;
     /* create custom radiobutton appearance */
     display: inline-block;
     width: 25px;
     height: 25px;
     padding: 6px;
     /* background-color only for content */
     background-clip: content-box;
     border: 2px solid #bbbbbb;
     background-color: #e7e6e7;
     border-radius: 50%;
   }
   
   /* appearance for checked radiobutton */
   input[type="radio"]:checked {
     background-color: #93e026;
   }
   
   /* optional styles, I'm using this for centering radiobuttons */
   .flex {
     display: flex;
     align-items: center;
   }

   _x000D_

   <div class="flex">
     <input type="radio" name="radio" id="radio1" />
     <label for="radio1">RadioButton1</label>
   </div>
   <div class="flex">
     <input type="radio" name="radio" id="radio2" />
     <label for="radio2">RadioButton2</label>
   </div>
   <div class="flex">
     <input type="radio" name="radio" id="radio3" />
     <label for="radio3">RadioButton3</label>
   </div>

   _x000D_

   _x000D_
   _x000D_

2. Via hiding radiobutton and setting custom radiobutton appearance to label's pseudoselector. By the way no need for absolute positioning here (I see absolute positioning in most demos). Demo:

   _x000D_

   _x000D_

   *,
   *:before,
   *:after {
     box-sizing: border-box;
   }
   
   input[type="radio"] {
     display: none;
   }
   
   input[type="radio"]+label:before {
     content: "";
     /* create custom radiobutton appearance */
     display: inline-block;
     width: 25px;
     height: 25px;
     padding: 6px;
     margin-right: 3px;
     /* background-color only for content */
     background-clip: content-box;
     border: 2px solid #bbbbbb;
     background-color: #e7e6e7;
     border-radius: 50%;
   }
   
   /* appearance for checked radiobutton */
   input[type="radio"]:checked + label:before {
     background-color: #93e026;
   }
   
   /* optional styles, I'm using this for centering radiobuttons */
   label {
     display: flex;
     align-items: center;
   }

   _x000D_

   <input type="radio" name="radio" id="radio1" />
   <label for="radio1">RadioButton1</label>
   <input type="radio" name="radio" id="radio2" />
   <label for="radio2">RadioButton2</label>
   <input type="radio" name="radio" id="radio3" />
   <label for="radio3">RadioButton3</label>

   _x000D_

   _x000D_
   _x000D_

I know this is not an ideal question to answer but as the OP seems to be a beginner, I'd love to share some basic knowledge with him... Hope everybody understands

OP, you can convert a string to type Boolean by using any of the methods stated below:

 string sample = "True";
 bool myBool = bool.Parse(sample);

 ///or

 bool myBool = Convert.ToBoolean(sample);

bool.Parse expects one parameter which in this case is sample, .ToBoolean also expects one parameter.

You can use TryParse which is the same as Parse but it doesn't throw any exception :)

  string sample = "false";
  Boolean myBool;

  if (Boolean.TryParse(sample , out myBool))
  {
  }

Please note that you cannot convert any type of string to type Boolean because the value of a Boolean can only be True or False

Hope you understand :)

Idiomatic Matlab plot(x1,y1,x2,y2) can be translated in R with ggplot2 for example in this way:

x1 <- seq(1,10,.2)
df1 <- data.frame(x=x1,y=log(x1),type="Log")
x2 <- seq(1,10)
df2 <- data.frame(x=x2,y=cumsum(1/x2),type="Harmonic")

df <- rbind(df1,df2)

library(ggplot2)
ggplot(df)+geom_line(aes(x,y,colour=type))

^{Inspired by Tingting Zhao's Dual line plots with different range of x-axis Using ggplot2.}

All you need to do is set the PATH environment variable in Windows to point to where your java6 bin directory is instead of the java7 directory.

Right click My Computer > Advanced System Settings > Advanced > Environmental Variables

If there is a JAVA_HOME environment variable set this to point to the correct directory as well.

INSERT INTO tblBrandinCategory (CategoryID, BrandID) 
       VALUES (@CategoryID, @BrandID)

END

The different methods are indications of priority. As you've listed them, they're going from least to most important. I think how you specifically map them to debug logs in your code depends on the component or app you're working on, as well as how Android treats them on different build flavors (eng, userdebug, and user). I have done a fair amount of work in the native daemons in Android, and this is how I do it. It may not apply directly to your app, but there may be some common ground. If my explanation sounds vague, it's because some of this is more of an art than a science. My basic rule is to be as efficient as possible, ensure you can reasonably debug your component without killing the performance of the system, and always check for errors and log them.

V - Printouts of state at different intervals, or upon any events occurring which my component processes. Also possibly very detailed printouts of the payloads of messages/events that my component receives or sends.

D - Details of minor events that occur within my component, as well as payloads of messages/events that my component receives or sends.

I - The header of any messages/events that my component receives or sends, as well as any important pieces of the payload which are critical to my component's operation.

W - Anything that happens that is unusual or suspicious, but not necessarily an error.

E - Errors, meaning things that aren't supposed to happen when things are working as they should.

The biggest mistake I see people make is that they overuse things like V, D, and I, but never use W or E. If an error is, by definition, not supposed to happen, or should only happen very rarely, then it's extremely cheap for you to log a message when it occurs. On the other hand, if every time somebody presses a key you do a Log.i(), you're abusing the shared logging resource. Of course, use common sense and be careful with error logs for things outside of your control (like network errors), or those contained in tight loops.

Maybe Bad

Log.i("I am here");

Good

Log.e("I shouldn't be here");

With all this in mind, the closer your code gets to "production ready", the more you can restrict the base logging level for your code (you need V in alpha, D in beta, I in production, or possibly even W in production). You should run through some simple use cases and view the logs to ensure that you can still mostly understand what's happening as you apply more restrictive filtering. If you run with the filter below, you should still be able to tell what your app is doing, but maybe not get all the details.

logcat -v threadtime MyApp:I *:S

For those of you who want to execute a side-effect only if an optional is absent

i.e. an equivalent of ifAbsent() or ifNotPresent() here is a slight modification to the great answers already provided.

myOptional.ifPresentOrElse(x -> {}, () -> {
  // logic goes here
})

The default generator for Windows seems to be set to NMAKE. Try to use:

cmake -G "MinGW Makefiles"

Or use the GUI, and select MinGW Makefiles when prompted for a generator. Don't forget to cleanup the directory where you tried to run CMake, or delete the cache in the GUI. Otherwise, it will try again with NMAKE.

use ${fn:length(companies) > 0} to check the size. This returns a boolean

The previous answers either suggest custom renderers or require you to keep track of the selected item either in your data objects or otherwise. This isn't really required, there is a way to link to the functioning of the ListView in a platform agnostic way. This can then be used to change the selected item in any way required. Colors can be modified, different parts of the cell shown or hidden depending on the selected state.

Let's add an IsSelected property to our ViewCell. There is no need to add it to the data object; the listview selects the cell, not the bound data.

public partial class SelectableCell : ViewCell {

  public static readonly BindableProperty IsSelectedProperty = BindableProperty.Create(nameof(IsSelected), typeof(bool), typeof(SelectableCell), false, propertyChanged: OnIsSelectedPropertyChanged);
  public bool IsSelected {
    get => (bool)GetValue(IsSelectedProperty);
    set => SetValue(IsSelectedProperty, value);
  }

  // You can omit this if you only want to use IsSelected via binding in XAML
  private static void OnIsSelectedPropertyChanged(BindableObject bindable, object oldValue, object newValue) {
    var cell = ((SelectableCell)bindable);
    // change color, visibility, whatever depending on (bool)newValue
  }

  // ...
}

To create the missing link between the cells and the selection in the list view, we need a converter (the original idea came from the Xamarin Forum):

public class IsSelectedConverter : IValueConverter {
  public object Convert(object value, Type targetType, object parameter, CultureInfo culture) =>
    value != null && value == ((ViewCell)parameter).View.BindingContext;

  public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) =>
    throw new NotImplementedException();
}

We connect the two using this converter:

<ListView x:Name="ListViewName">
  <ListView.ItemTemplate>
    <DataTemplate>
      <local:SelectableCell x:Name="ListViewCell"
        IsSelected="{Binding SelectedItem, Source={x:Reference ListViewName}, Converter={StaticResource IsSelectedConverter}, ConverterParameter={x:Reference ListViewCell}}" />
    </DataTemplate>
  </ListView.ItemTemplate>
</ListView>

This relatively complex binding serves to check which actual item is currently selected. It compares the SelectedItem property of the list view to the BindingContext of the view in the cell. That binding context is the data object we actually bind to. In other words, it checks whether the data object pointed to by SelectedItem is actually the data object in the cell. If they are the same, we have the selected cell. We bind this into to the IsSelected property which can then be used in XAML or code behind to see if the view cell is in the selected state.

There is just one caveat: if you want to set a default selected item when your page displays, you need to be a bit clever. Unfortunately, Xamarin Forms has no page Displayed event, we only have Appearing and this is too early for setting the default: the binding won't be executed then. So, use a little delay:

protected override async void OnAppearing() {
  base.OnAppearing();

  Device.BeginInvokeOnMainThread(async () => {
    await Task.Delay(100);
    ListViewName.SelectedItem = ...;
  });
}

You don't need JDK to run Java based programs. JDK is for development which stands for Java Development Kit.

You need JRE which should be there in Mac.

Try: java -jar Myjar_file.jar

EDIT: According to this article, for Mac OS 10

The Java runtime is no longer installed automatically as part of the OS installation.

Then, you need to install JRE to your machine.

If you need use it as a default configuration, just place min: 0 inside the node defaults.scale.ticks, as follows:

defaults: {
  global: {...},
  scale: {
    ...
    ticks: { min: 0 },
  }
},

I managed to get it run on linux

1. run the docker postgres - make sure the port is published, I use alpine because it's lightweight.

   docker run --rm -P -p 127.0.0.1:5432:5432 -e POSTGRES_PASSWORD="1234" --name pg postgres:alpine
   

2. using another terminal, access the database from the host using the postgres uri

   psql postgresql://postgres:1234@localhost:5432/postgres
   

for mac users, replace psql with pgcli

4- Restart Apache
Don't forget restart Apache or all servises!!!

as a beginner, i import acm packages, and in this package, run() starts executing of a thread, init() initialize the Java Applet.

I am not sure if you got this resolved. To follow up on "CommonsWare's" comment.

That is not a valid string representation of a Uri. A Uri has a scheme, and "/external/images/media/470939" does not have a scheme.

Change

Uri uri=Uri.parse("/external/images/media/470939");

to

Uri uri=Uri.parse("content://external/images/media/470939");

in my case

Uri uri = Uri.parse("content://media/external/images/media/6562");

The main point of the differences as pointed out @BizApps is that Load event happens right after the ViewState is populated while PreRender event happens later, right before Rendering phase, and after all individual children controls' action event handlers are already executing. Therefore, any modifications done by the controls' actions event handler should be updated in the control hierarchy during PreRender as it happens after.

Here's a helpful article on long polling (long-held HTTP request) using jQuery. A code snippet derived from this article:

(function poll() {
    setTimeout(function() {
        $.ajax({
            url: "/server/api/function",
            type: "GET",
            success: function(data) {
                console.log("polling");
            },
            dataType: "json",
            complete: poll,
            timeout: 2000
        })
    }, 5000);
})();

This will make the next request only after the ajax request has completed.

A variation on the above that will execute immediately the first time it is called before honouring the wait/timeout interval.

(function poll() {
    $.ajax({
        url: "/server/api/function",
        type: "GET",
        success: function(data) {
            console.log("polling");
        },
        dataType: "json",
        complete: setTimeout(function() {poll()}, 5000),
        timeout: 2000
    })
})();

The 1s are because everything is perfectly correlated with itself, and the NAs are because there are NAs in your variables.

You will have to specify how you want R to compute the correlation when there are missing values, because the default is to only compute a coefficient with complete information.

You can change this behavior with the use argument to cor, see ?cor for details.

I don't know if this is exactly what you want, but did you know you can use the CSS overflow property to create scrollbars?

CSS:

div.box{
  width: 200px;
  height: 200px;
  overflow: scroll;
}

HTML:

<div class="box">
  All your text content...
</div>

As I found by the previous answers, three steps are needed to change the type of a column:

Step 1:

Generate a new migration file using this code:

rails g migration sample_name_change_column_type

Step 2:

Go to /db/migrate folder and edit the migration file you made. There are two different solutions.

1. def change
       change_column(:table_name, :column_name, :new_type)
   end
   

2.

    def up
        change_column :table_name, :column_name, :new_type
    end

    def down
        change_column :table_name, :column_name, :old_type
    end

Step 3:

Don't forget to do this command:

rake db:migrate

I have tested this solution for Rails 4 and it works well.

Another option for Windows that will automatically use the most recent version of Python installed, and also doesn't make you look for the installation path:

Target: pyw -m idlelib
Start in: Wherever you want

If you know nobody has pulled your un-amended commit, use the --force-with-lease option of git push.

In TortoiseGit, you can do the same thing under "Push..." options "Force: May discard" and checking "known changes".

Force (May discard known changes) allows the remote repository to accept a safer non-fast-forward push. This can cause the remote repository to lose commits; use it with care. This can prevent from losing unknown changes from other people on the remote. It checks if the server branch points to the same commit as the remote-tracking branch (known changes). If yes, a force push will be performed. Otherwise it will be rejected. Since git does not have remote-tracking tags, tags cannot be overwritten using this option.

If we have parameter like below in our POM XML

<version>${project.version}.${svn.version}</version>
  <packaging>war</packaging>

I run maven command line as follows :

mvn clean install package -Dproject.version=10 -Dsvn.version=1

Interestingly array is randomly accessible by the index. And removing randomly an element may impact the indexes of other elements as well.

    int remove_element(int*from, int total, int index) {
            if((total - index - 1) > 0) {
                      memmove(from+i, from+i+1, sizeof(int)*(total-index-1));
            }
            return total-1; // return the new array size
    }

Note that memcpy will not work in this case because of the overlapping memory.

One of the efficient way (better than memory move) to remove one random element is swapping with the last element.

    int remove_element(int*from, int total, int index) {
            if(index != (total-1))
                    from[index] = from[total-1];
            return total; // **DO NOT DECREASE** the total here
    }

But the order is changed after the removal.

Again if the removal is done in loop operation then the reordering may impact processing. Memory move is one expensive alternative to keep the order while removing an array element. Another of the way to keep the order while in a loop is to defer the removal. It can be done by validity array of the same size.

    int remove_element(int*from, int total, int*is_valid, int index) {
            is_valid[index] = 0;
            return total-1; // return the number of elements
    }

It will create a sparse array. Finally, the sparse array can be made compact(that contains no two valid elements that contain invalid element between them) by doing some reordering.

    int sparse_to_compact(int*arr, int total, int*is_valid) {
            int i = 0;
            int last = total - 1;
            // trim the last invalid elements
            for(; last >= 0 && !is_valid[last]; last--); // trim invalid elements from last

            // now we keep swapping the invalid with last valid element
            for(i=0; i < last; i++) {
                    if(is_valid[i])
                            continue;
                    arr[i] = arr[last]; // swap invalid with the last valid
                    last--;
                    for(; last >= 0 && !is_valid[last]; last--); // trim invalid elements
            }
            return last+1; // return the compact length of the array
    }

would it not be better to explicitly assign value 0 to None constant? Why?

Because default enum value is equal to 0, if You would call default(Color) it would print None.

Because it is at first position, assigning literal value 0 to any other constant would change that behaviour, also changing order of occurrence would change output of default(Color) (https://stackoverflow.com/a/4967673/8611327)

Just add the function reference to the $scope in the controller:

for example if you want the function MyFunction to work in ng-click just add to the controller:

app.controller("MyController", ["$scope", function($scope) {
   $scope.MyFunction = MyFunction;
}]);

We had a situation where IE forced us to post as text/plain, so we had to manually parse the parameters using getReader. The servlet was being used for long polling, so when AsyncContext::dispatch was executed after a delay, it was literally reposting the request empty handed.

So I just stored the post in the request when it first appeared by using HttpServletRequest::setAttribute. The getReader method empties the buffer, where getParameter empties the buffer too but stores the parameters automagically.

    String input = null;

    // we have to store the string, which can only be read one time, because when the
    // servlet awakens an AsyncContext, it reposts the request and returns here empty handed
    if ((input = (String) request.getAttribute("com.xp.input")) == null) {
        StringBuilder buffer = new StringBuilder();
        BufferedReader reader = request.getReader();

        String line;
        while((line = reader.readLine()) != null){
            buffer.append(line);
        }
        // reqBytes = buffer.toString().getBytes();

        input = buffer.toString();
        request.setAttribute("com.xp.input", input);
    }

    if (input == null) {
        response.setContentType("text/plain");
        PrintWriter out = response.getWriter();
        out.print("{\"act\":\"fail\",\"msg\":\"invalid\"}");
    }       

Gallery is the best solution, i have tried it. I was working on one mail app, in which mails in the inbox where displayed as listview, i wanted an horizontal view, i just converted listview to gallery and everything worked fine as i needed without any errors. For the scroll effect i enabled gesture listener for the gallery. I hope this answer may help u.

I see many answers are suggesting to return n && !(n & (n - 1)) but to my experience if the input values are negative it returns false values. I will share another simple approach here since we know a power of two number have only one set bit so simply we will count number of set bit this will take O(log N) time.

while (n > 0) {
    int count = 0;
    n = n & (n - 1);
    count++;
}
return count == 1;

Check this article to count no. of set bits

You should use hyphens in a crawlable web application URL. Why? Because the hyphen separates words (so that a search engine can index the individual words), and is not a word character. Underscore is a word character, meaning it should be considered part of a word.

Double-click this in Chrome: camelCase
Double-click this in Chrome: under_score
Double-click this in Chrome: hyphen-ated

See how Chrome (I hear Google makes a search engine too) only thinks one of those is two words?

camelCase and underscore also require the user to use the shift key, whereas hyphenated does not.

So if you should use hyphens in a crawlable web application, why would you bother doing something different in an intranet application? One less thing to remember.

I set iframe src attribute later in my app. To get rid of the cached content inside iframe at the start of the application I simply do:

myIframe.src = "";

No, your algorithm works but your Write operation is misplaced within the outer loop.

int[] arr = { 800, 11, 50, 771, 649, 770, 240, 9 };

int temp = 0;

for (int write = 0; write < arr.Length; write++) {
    for (int sort = 0; sort < arr.Length - 1; sort++) {
        if (arr[sort] > arr[sort + 1]) {
            temp = arr[sort + 1];
            arr[sort + 1] = arr[sort];
            arr[sort] = temp;
        }
    }
}

for (int i = 0; i < arr.Length; i++)
    Console.Write(arr[i] + " ");

Console.ReadKey();

sqlplus user/password@sid < sqlfile.sql

This will also work from the DOS command line. In this case the file sqlfile.sql contains the SQL you wish to execute.

Imo, the best way to parse your JSON response with GSON would be creating classes that "match" your response and then use Gson.fromJson() method.
For example:

class Response {
    Map<String, App> descriptor;
    // standard getters & setters...
}

class App {
  String name;
  int age;
  String[] messages;
  // standard getters & setters...
}

Then just use:

Gson gson = new Gson();
Response response = gson.fromJson(yourJson, Response.class);

Where yourJson can be a String, any Reader, a JsonReader or a JsonElement.

Finally, if you want to access any particular field, you just have to do:

String name = response.getDescriptor().get("app3").getName();

You can always parse the JSON manually as suggested in other answers, but personally I think this approach is clearer, more maintainable in long term and it fits better with the whole idea of JSON.

You might want to try using something like this

curl = require('node-curl');
curl('www.google.com', function(err) {
  console.info(this.status);
  console.info('-----');
  console.info(this.body);
  console.info('-----');
  console.info(this.info('SIZE_DOWNLOAD'));
});

here is simple JQuery to do this to make div draggable with in only container :

$("#containerdiv div").draggable( {containment: "#containerdiv ", scroll: false} );

The best solution in my opinion is add a plugin in the pom.xml, and you don't need to do anything else all the time:

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <jvmArguments>
                        -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=9898
                    </jvmArguments>
                </configuration>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

There are a million ways to do this.

The first one would be to go ahead and run the array through foreach anyway, assuming you do have an array.

In other cases this is what you might need:

foreach ((array) $items as $item) {
    print $item;
}

Note: to all the people complaining about typecast, please note that the OP asked cleanest way to skip a foreach if array is empty (emphasis is mine). A value of true, false, numbers or strings is not considered empty. In addition, this would work with objects implementing \Traversable, whereas is_array wouldn't work.

First off, EC2 and Elastic Compute Cloud are the same thing.

Next, AWS encompasses the range of Web Services that includes EC2 and Elastic Beanstalk. It also includes many others such as S3, RDS, DynamoDB, and all the others.

EC2

EC2 is Amazon's service that allows you to create a server (AWS calls these instances) in the AWS cloud. You pay by the hour and only what you use. You can do whatever you want with this instance as well as launch n number of instances.

Elastic Beanstalk

Elastic Beanstalk is one layer of abstraction away from the EC2 layer. Elastic Beanstalk will setup an "environment" for you that can contain a number of EC2 instances, an optional database, as well as a few other AWS components such as a Elastic Load Balancer, Auto-Scaling Group, Security Group. Then Elastic Beanstalk will manage these items for you whenever you want to update your software running in AWS. Elastic Beanstalk doesn't add any cost on top of these resources that it creates for you. If you have 10 hours of EC2 usage, then all you pay is 10 compute hours.

Running Wordpress

For running Wordpress, it is whatever you are most comfortable with. You could run it straight on a single EC2 instance, you could use a solution from the AWS Marketplace, or you could use Elastic Beanstalk.

What to pick?

In the case that you want to reduce system operations and just focus on the website, then Elastic Beanstalk would be the best choice for that. Elastic Beanstalk supports a PHP stack (as well as others). You can keep your site in version control and easily deploy to your environment whenever you make changes. It will also setup an Autoscaling group which can spawn up more EC2 instances if traffic is growing.

Here's the first result off of Google when searching for "elastic beanstalk wordpress": https://www.otreva.com/blog/deploying-wordpress-amazon-web-services-aws-ec2-rds-via-elasticbeanstalk/

You could use grep and sed together. This allows you to search subdirectories recursively.

Linux: grep -r -l <old> * | xargs sed -i 's/<old>/<new>/g'
OS X: grep -r -l <old> * | xargs sed -i '' 's/<old>/<new>/g'

For grep:
    -r recursively searches subdirectories 
    -l prints file names that contain matches
For sed:
    -i extension (Note: An argument needs to be provided on OS X)

KeyStore Explorer open source visual tool to manage keystores.

You can hide the back button using left:null, but for android devices it's still able to go back when the user presses the back button. You need to reset the navigation state and hide the button with left:null

Here are the docs for resetting navigation state:
https://reactnavigation.org/docs/navigation-actions#reset

This solution works for react-navigator 1.0.0-beta.7, however left:null no longer works for the latest version.

In non-interactive env, we have to use plt.show(block=True)

As stated in the answer by Henrik, titles are left-aligned by default starting with ggplot 2.2.0. Titles can be centered by adding this to the plot:

theme(plot.title = element_text(hjust = 0.5))

However, if you create many plots, it may be tedious to add this line everywhere. One could then also change the default behaviour of ggplot with

theme_update(plot.title = element_text(hjust = 0.5))

Once you have run this line, all plots created afterwards will use the theme setting plot.title = element_text(hjust = 0.5) as their default:

theme_update(plot.title = element_text(hjust = 0.5))
ggplot() + ggtitle("Default is now set to centered")

To get back to the original ggplot2 default settings you can either restart the R session or choose the default theme with

theme_set(theme_gray())

Solution #2 of @Ben's answer is not reproducible in other more generic examples. It happens to give the correct lookup in the example because the unique HouseType in houses appear in increasing order. Try this:

hous <- read.table(header = TRUE,   stringsAsFactors = FALSE,   text="HouseType HouseTypeNo
  Semi            1
  ECIIsHome       17
  Single          2
  Row             3
  Single          2
  Apartment       4
  Apartment       4
  Row             3")

largetable <- data.frame(HouseType = as.character(sample(unique(hous$HouseType), 1000, replace = TRUE)), stringsAsFactors = FALSE)
lookup <- unique(hous)

Bens solution#2 gives

housenames <- as.numeric(1:length(unique(hous$HouseType)))
names(housenames) <- unique(hous$HouseType)
base2 <- data.frame(HouseType = largetable$HouseType,
                    HouseTypeNo = (housenames[largetable$HouseType]))

which when

unique(base2$HouseTypeNo[ base2$HouseType=="ECIIsHome" ])
[1] 2

when the correct answer is 17 from the lookup table

The correct way to do it is

 hous <- read.table(header = TRUE,   stringsAsFactors = FALSE,   text="HouseType HouseTypeNo
      Semi            1
      ECIIsHome       17
      Single          2
      Row             3
      Single          2
      Apartment       4
      Apartment       4
      Row             3")

largetable <- data.frame(HouseType = as.character(sample(unique(hous$HouseType), 1000, replace = TRUE)), stringsAsFactors = FALSE)

housenames <- tapply(hous$HouseTypeNo, hous$HouseType, unique)
base2 <- data.frame(HouseType = largetable$HouseType,
  HouseTypeNo = (housenames[largetable$HouseType]))

Now the lookups are performed correctly

unique(base2$HouseTypeNo[ base2$HouseType=="ECIIsHome" ])
ECIIsHome 
       17

I tried to edit Bens answer but it gets rejected for reasons I cannot understand.

If you want a distiction for this case I would recommend to use a matrix instead, where:

matrix([1,2,3]) == matrix([1,2,3]).transpose()

gives:

matrix([[ True, False, False],
        [False,  True, False],
        [False, False,  True]], dtype=bool)

You can also use a ndarray explicitly adding a second dimension:

array([1,2,3])[None,:]
#array([[1, 2, 3]])

and:

array([1,2,3])[:,None]
#array([[1],
#       [2],
#       [3]])

The browser discloses it in navigator.userAgent. If you're using jQuery, you're better off using jQuery.browser as @Rab Nawaz said. However, as the API documentation says, it's better to check for feature support if possible. Quoting the documentation:

We recommend against using this property; please try to use feature detection instead (see jQuery.support). jQuery.browser may be moved to a plugin in a future release of jQuery.

Here is a code example:

function isIE() {
    if (window.jQuery) {
        return jQuery.browser.msie || false;
    } else {
        // adapted from jQuery's source:
        return navigator.userAgent.toLowerCase().indexOf('msie') >= 0;
    }
}

Not sure if this is the most elegant solution (this is what I used), but you could scale your data to the range between 0 to 1 and then modify the colorbar:

import matplotlib as mpl
...
ax, _ = mpl.colorbar.make_axes(plt.gca(), shrink=0.5)
cbar = mpl.colorbar.ColorbarBase(ax, cmap=cm,
                       norm=mpl.colors.Normalize(vmin=-0.5, vmax=1.5))
cbar.set_clim(-2.0, 2.0)

With the two different limits you can control the range and legend of the colorbar. In this example only the range between -0.5 to 1.5 is show in the bar, while the colormap covers -2 to 2 (so this could be your data range, which you record before the scaling).

So instead of scaling the colormap you scale your data and fit the colorbar to that.

It's possible to store in a profile.ps1 file any PowerShell code to be executed each time PowerShell starts. There are at least 6 different paths where to store the code depending on which user has to execute it. We will consider only 2 of them: the "all users" and the "only your user" paths (follow the previous link for further options).

To answer your question, you only have to create a profile.ps1 file containing the code you want to be executed, that is:

New-Alias Goto Set-Location

and save it in the proper path:

• "$Home\Documents" (usually C:\Users<yourname>\Documents): Only your user will execute the code. This is the reccomanded place.
  You can quickly find your profile location by running echo $profile in PowerShell
• $PsHome (C:\Windows\System32\WindowsPowerShell\v1.0): Every user will execute the code.

IMPORTANT: Remember you need to restart your PowerShell instances to apply the changes.

TIPS

• If both paths contain a profile.ps1 file, the all-users one is executed first, then the user-specific one. This means the user-specific commands will overwrite variables in case of duplicates or conflicts.

• Always put the code in the user-specific profile if there is no need to extend its execution to every user. This is safer because you don't pollute other users' space (usually, you don't want to do that).
  Another advantage is that you don't need administrator rights to add the file to your user-space (you do for anything in C:\Windows\System32).

• If you really need to execute the profile code for every user, mind that the $PsHome path is different for 32bit and 64bit instances of PowerShell. You should consider both environments if you want to always execute the profile code.
  The paths are:

  • C:\Windows\System32\WindowsPowerShell\v1.0 for the 64bit environment
  • C:\Windows\SysWow64\WindowsPowerShell\v1.0 for the 32bit one (Yeah I know, the folder naming is counterintuitive, but it's correct).

Use schema name with period in psql command to obtain information about this schema.

Setup:

test=# create schema test_schema;
CREATE SCHEMA
test=# create table test_schema.test_table (id int);
CREATE TABLE
test=# create table test_schema.test_table_2 (id int);
CREATE TABLE

Show list of relations in test_schema:

test=# \dt test_schema.
               List of relations
   Schema    |     Name     | Type  |  Owner   
-------------+--------------+-------+----------
 test_schema | test_table   | table | postgres
 test_schema | test_table_2 | table | postgres
(2 rows)

Show test_schema.test_table definition:

test=# \d test_schema.test_table
Table "test_schema.test_table"
 Column |  Type   | Modifiers 
--------+---------+-----------
 id     | integer | 

Show all tables in test_schema:

test=# \d test_schema.
Table "test_schema.test_table"
 Column |  Type   | Modifiers 
--------+---------+-----------
 id     | integer | 

Table "test_schema.test_table_2"
 Column |  Type   | Modifiers 
--------+---------+-----------
 id     | integer | 

etc...

In the same xml I have used next:

    <RelativeLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="#ffffff" <!-- border color -->
        android:padding="3dp"> <!-- border width -->

        <ImageView
            android:layout_width="160dp"
            android:layout_height="120dp"
            android:layout_centerHorizontal="true"
            android:layout_centerVertical="true"
            android:scaleType="centerCrop" />
    </RelativeLayout>

There is some progress for Visual studio 2013 developers :-D woot woot! See blog post Visual Studio Installer Projects Extension.

Link and information were retrieved from Brian Harry's blog post Creating installers with Visual Studio.

This was made better in python3 and documented in the stdlib documentation

The urllib.request.Request class gained a method=... parameter in python3.

Some sample usage:

req = urllib.request.Request('https://example.com/', data=b'DATA!', method='PUT')
urllib.request.urlopen(req)

You need to use these parameters in your list view:

• Scroll lv.setTranscriptMode(ListView.TRANSCRIPT_MODE_ALWAYS_SCROLL);

• Set the head of the list to it bottom lv.setStackFromBottom(true);

You can also set these parameters in XML, eg. like this:

<ListView
   ...
   android:transcriptMode="alwaysScroll"
   android:stackFromBottom="true" />

The main point is this:

col-lg-* col-md-* col-xs-* col-sm define how many columns will there be in these different screen sizes.

Example: if you want there to be two columns in desktop screens and in phone screens you put two col-md-6 and two col-xs-6 classes in your columns.

If you want there to be two columns in desktop screens and only one column in phone screens (ie two rows stacked on top of each other) you put two col-md-6 and two col-xs-12 in your columns and because sum will be 24 they will auto stack on top of each other, or just leave xs style out.

For make a list, simply do that

colors=(red orange white "light gray")

Technically is an array, but - of course - it has all list features.
Even python list are implemented with array
