<create-report-card-form [currentReportCardCount]="providerData.reportCards.length" ...
                         ^^^^^^^^^^^^^^^^^^^^^^^^

In your HomeComponent template, you are trying to bind to an input on the CreateReportCardForm component that doesn't exist.

In CreateReportCardForm, these are your only three inputs:

@Input() public reportCardDataSourcesItems: SelectItem[];
@Input() public reportCardYearItems: SelectItem[];
@Input() errorMessages: Message[];

Add one for currentReportCardCount and you should be good to go.

inside your save button click add this code :

$("#btnSave").click(function (e) {
  e.preventDefault();
  swal("Are you sure?", {
    buttons: {
      yes: {
        text: "Yes",
        value: "yes"
      },
      no: {
        text: "No",
        value: "no"
      }
    }
  }).then((value) => {
    if (value === "yes") {
      // Add Your Custom Code for CRUD
    }
    return false;
  });
});

I just struggled with this. I upgraded from sweetalert 1 -> 2. This library: https://sweetalert.js.org/guides/

The example from documentation "string" doesn't work as I expected. You just can't put it like this.

content: `my es6 string <strong>template</strong>` 

How I solved it:

const template = (`my es6 string <strong'>${variable}</strong>`);
content: {
      element: 'p',
      attributes: {
        innerHTML: `${template}`,
      },
    }

There is no documentation how to do this, it was pure trial and error, but at least seems to work.

Update (thanks to @chaost for pointing this update out):

Mads Torgersen: "Extension everything didn’t make it into C# 8.0. It got “caught up”, if you will, in a very exciting debate about the further future of the language, and now we want to make sure we don’t add it in a way that inhibits those future possibilities. Sometimes language design is a very long game!"

I stopped counting how many times over the years I opened this question with hopes to have seen this implemented.

Well, finally we can all rejoice! Microsoft is going to introduce this in their upcoming C# 8 release.

So instead of doing this...

public static class IntExtensions
{
   public static bool Even(this int value)
   {
        return value % 2 == 0;
   }
}

We'll be finally able to do it like so...

public extension IntExtension extends int
{
    public bool Even => this % 2 == 0;
}

I prefer a mutex solution similar to the following. As this way it re-focuses on the app if it is already loaded

using System.Threading;

[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool SetForegroundWindow(IntPtr hWnd);

/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
{
   bool createdNew = true;
   using (Mutex mutex = new Mutex(true, "MyApplicationName", out createdNew))
   {
      if (createdNew)
      {
         Application.EnableVisualStyles();
         Application.SetCompatibleTextRenderingDefault(false);
         Application.Run(new MainForm());
      }
      else
      {
         Process current = Process.GetCurrentProcess();
         foreach (Process process in Process.GetProcessesByName(current.ProcessName))
         {
            if (process.Id != current.Id)
            {
               SetForegroundWindow(process.MainWindowHandle);
               break;
            }
         }
      }
   }
}

Select [insert your fields here]
from tablename 
where signin = (select max(signin) from tablename where ID = 1)

Posting data is a matter of sending a query string (just like the way you would send it with an URL after the ?) as the request body.

This requires Content-Type and Content-Length headers, so the receiving server knows how to interpret the incoming data. ^(*)

var querystring = require('querystring');
var http = require('http');

var data = querystring.stringify({
      username: yourUsernameValue,
      password: yourPasswordValue
    });

var options = {
    host: 'my.url',
    port: 80,
    path: '/login',
    method: 'POST',
    headers: {
        'Content-Type': 'application/x-www-form-urlencoded',
        'Content-Length': Buffer.byteLength(data)
    }
};

var req = http.request(options, function(res) {
    res.setEncoding('utf8');
    res.on('data', function (chunk) {
        console.log("body: " + chunk);
    });
});

req.write(data);
req.end();

^(*) Sending data requires the Content-Type header to be set correctly, i.e. application/x-www-form-urlencoded for the traditional format that a standard HTML form would use.

It's easy to send JSON (application/json) in exactly the same manner; just JSON.stringify() the data beforehand.

URL-encoded data supports one level of structure (i.e. key and value). JSON is useful when it comes to exchanging data that has a nested structure.

The bottom line is: The server must be able to interpret the content type in question. It could be text/plain or anything else; there is no need to convert data if the receiving server understands it as it is.

Add a charset parameter (e.g. application/json; charset=Windows-1252) if your data is in an unusual character set, i.e. not UTF-8. This can be necessary if you read it from a file, for example.

Another option is to use Javascript:

if (document.getElementById('selectID').value == '1') {
       document.getElementById('optionID').style.color = '#000';

(Not as clean as the CSS attribute selector, but more powerful)

If you want to do it via javascript rather than CSS you can use:

var link = document.getElementById('nav-ask');
link.style.display = 'none'; //or
link.style.visibility = 'hidden';

depending on what you want to do.

This is the code to select value from the drop down

The value for selectlocator will be the xpath or name of dropdown box, and for optionLocator will have the value to be selected from the dropdown box.

public static boolean select(final String selectLocator,
        final String optionLocator) {
    try {
        element(selectLocator).clear();
        element(selectLocator).sendKeys(Keys.PAGE_UP);
        for (int k = 0; k <= new Select(element(selectLocator))
                .getOptions().size() - 1; k++) {
            combo1.add(element(selectLocator).getValue());
            element(selectLocator).sendKeys(Keys.ARROW_DOWN);
        }
        if (combo1.contains(optionLocator)) {
            element(selectLocator).clear();
            new Select(element(selectLocator)).selectByValue(optionLocator);
            combocheck = element(selectLocator).getValue();
            combo = "";

            return true;
        } else {
            element(selectLocator).clear();
            combo = "The Value " + optionLocator
                    + " Does Not Exist In The Combobox";
            return false;
        }
    } catch (Exception e) {
        e.printStackTrace();
        errorcontrol.add(e.getMessage());
        return false;
    }
}



private static RenderedWebElement element(final String locator) {
    try {

        return (RenderedWebElement) drivers.findElement(by(locator));
    } catch (Exception e) {
        errorcontrol.add(e.getMessage());
        return (RenderedWebElement) drivers.findElement(by(locator));
    }
}

I think that the URI class is the one that you are looking for.

Yes, the first one is a static method also called class method, while the second one is an instance method.

Consider the following examples, to understand it in more detail.

In ES5

function Person(firstName, lastName) {
   this.firstName = firstName;
   this.lastName = lastName;
}

Person.isPerson = function(obj) {
   return obj.constructor === Person;
}

Person.prototype.sayHi = function() {
   return "Hi " + this.firstName;
}

In the above code, isPerson is a static method, while sayHi is an instance method of Person.

Below, is how to create an object from Person constructor.

var aminu = new Person("Aminu", "Abubakar");

Using the static method isPerson.

Person.isPerson(aminu); // will return true

Using the instance method sayHi.

aminu.sayHi(); // will return "Hi Aminu"

In ES6

class Person {
   constructor(firstName, lastName) {
      this.firstName = firstName;
      this.lastName = lastName;
   }

   static isPerson(obj) {
      return obj.constructor === Person;
   }

   sayHi() {
      return `Hi ${this.firstName}`;
   }
}

Look at how static keyword was used to declare the static method isPerson.

To create an object of Person class.

const aminu = new Person("Aminu", "Abubakar");

Using the static method isPerson.

Person.isPerson(aminu); // will return true

Using the instance method sayHi.

aminu.sayHi(); // will return "Hi Aminu"

NOTE: Both examples are essentially the same, JavaScript remains a classless language. The class introduced in ES6 is primarily a syntactical sugar over the existing prototype-based inheritance model.

Using CSS3 you don't need to make your own image with the transparency.

Just have a div with the following

position:absolute;
left:0;
background: rgba(255,255,255,.5);

The last parameter in background (.5) is the level of transparency (a higher number is more opaque).

Example Fiddle

I edit Mark Rajcok's focusMe directive to work for multiple focus in one element.

HTML:

<input  focus-me="myInputFocus"  type="text">

in AngularJs Controller:

$scope.myInputFocus= true;

AngulaJS Directive:

app.directive('focusMe', function ($timeout, $parse) {
    return {
        link: function (scope, element, attrs) {
            var model = $parse(attrs.focusMe);
            scope.$watch(model, function (value) {
                if (value === true) {
                    $timeout(function () {
                        scope.$apply(model.assign(scope, false));
                        element[0].focus();
                    }, 30);
                }
            });
        }
    };
});

Very few posts suggest using LOGON_TYPE_NEW_CREDENTIALS instead of LOGON_TYPE_NETWORK or LOGON_TYPE_INTERACTIVE. I had an impersonation issue with one machine connected to a domain and one not, and this fixed it. The last code snippet in this post suggests that impersonating across a forest does work, but it doesn't specifically say anything about trust being set up. So this may be worth trying:

const int LOGON_TYPE_NEW_CREDENTIALS = 9;
const int LOGON32_PROVIDER_WINNT50 = 3;
bool returnValue = LogonUser(user, domain, password,
            LOGON_TYPE_NEW_CREDENTIALS, LOGON32_PROVIDER_WINNT50,
            ref tokenHandle);

MSDN says that LOGON_TYPE_NEW_CREDENTIALS only works when using LOGON32_PROVIDER_WINNT50.

try,

str_list = " ".join([str(ele) for ele in numlist])

this statement will give you each element of your list in string format

print("The list now looks like [{0}]".format(str_list))

and,

change print(numlist.pop(2)+" has been removed") to

print("{0} has been removed".format(numlist.pop(2)))

as well.

Review the pom.xml file inside of target/checkout/. Chances are, the pom.xml in your trunk or master branch does not have the distributionManagement tag.

I believe it's just a convention for things that are boolean. A bit like saying "IsValid".

In command line it's better to use REG tool rather than REGEDIT:

REG IMPORT yourfile.reg

REG is designed for console mode, while REGEDIT is for graphical mode. This is why running regedit.exe /S yourfile.reg is a bad idea, since you will not be notified if the there's an error, whereas REG Tool will prompt:

>  REG IMPORT missing_file.reg

ERROR: Error opening the file. There may be a disk or file system error.

>  %windir%\System32\reg.exe /?

I know i am late to the party but hope this helps someone who will do the same with Class binding

var newEntry = new MyClassObject();

var bindingSource = dataGridView.DataSource as BindingSource;
var myClassObjects = bindingSource.DataSource as List<MyClassObject>;
myClassObjects.Add(newEntry);
bindingSource.DataSource = myClassObjects;

dataGridView.DataSource = null;
dataGridView.DataSource = bindingSource;
dataGridView.Update();
dataGridView.Refresh();

You must use OpenSSL and keytool.

OpenSSL for CER & PVK file > P12

openssl pkcs12 -export -name servercert -in selfsignedcert.crt -inkey serverprivatekey.key -out myp12keystore.p12

Keytool for p12 > JKS

keytool -importkeystore -destkeystore mykeystore.jks -srckeystore myp12keystore.p12 -srcstoretype pkcs12 -alias servercert

I would recommend using the Windows package installr to accomplish this. Not only will the package update your R version, but it will also copy and update all of your packages. There is a blog on the subject here. Simply run the following commands in R Studio and follow the prompts:

# installing/loading the package:
if(!require(installr)) {
install.packages("installr"); require(installr)} #load / install+load installr

# using the package:
updateR() # this will start the updating process of your R installation.  It will check for newer versions, and if one is available, will guide you through the decisions you'd need to make.

I do a lot of such presentation and use Monaco for code and Chalkboard for text (within a template that, overall, has only small changes from the Blackboard one supplied with Keynote). Look at any of my presentations' PDFs (e.g. this one) and you can decide whether you like the effect.

If we have 3 parameters (t0, a0, a1) for Relu, that is we want to implement

if x > t0:
    x = x * a1
else:
    x = x * a0

We can use the following code:

X = X * (X > t0) * a1 +  X * (X < t0) * a0

X there is a matrix.

As of jackson 2.7.4 (or earlier maybe), the class is in jacskon-jaxrs-base.jar, which is contained in jackson-jaxrs-json-provider

In XML there can be only one root element - you have two - heading and song.

If you restructure to something like:

<?xml version="1.0" encoding="UTF-8"?>
<song> 
 <heading>
 The Twelve Days of Christmas
 </heading>
 ....
</song>

The error about well-formed XML on the root level should disappear (though there may be other issues).

With Project JUnion you can use structs in Java by annotating a class with @Struct annotation

@Struct
class Member {
  string FirstName; 
  string LastName;  
  int BirthYear; 
}

More info at the project's website: https://tehleo.github.io/junion/

The post above that mentioned strategies didn't stress enough what a nice lightweight implementation of the strategy pattern using enums gets you:

public enum Strategy {

  A {
    @Override
    void execute() {
      System.out.print("Executing strategy A");
    }
  },

  B {
    @Override
    void execute() {
      System.out.print("Executing strategy B");
    }
  };

  abstract void execute();
}

You can have all your strategies in one place without needing a separate compilation unit for each. You get a nice dynamic dispatch just with:

Strategy.valueOf("A").execute();

Makes java read almost like a nice loosely typed language!

I display images in windows forms when I put it in Load event like this:

    private void Form1_Load( object sender , EventArgs e )
    {
        pictureBox1.ImageLocation = "./image.png"; //path to image
        pictureBox1.SizeMode = PictureBoxSizeMode.AutoSize;
    }

Portability between Linux and Windows is a big headache, since Linux is a POSIX-conformant system with - generally - a proper, high quality toolchain for C, whereas Windows doesn't even provide a lot of functions in the C standard library.

However, if you want to stick to the standard, you can write something like this:

#include <stdio.h>
#include <stdlib.h>

FILE *f = fopen("textfile.txt", "rb");
fseek(f, 0, SEEK_END);
long fsize = ftell(f);
fseek(f, 0, SEEK_SET);  /* same as rewind(f); */

char *string = malloc(fsize + 1);
fread(string, 1, fsize, f);
fclose(f);

string[fsize] = 0;

Here string will contain the contents of the text file as a properly 0-terminated C string. This code is just standard C, it's not POSIX-specific (although that it doesn't guarantee it will work/compile on Windows...)

You can use isin method:

In [1]: df = pd.DataFrame({'A': [5,6,3,4], 'B': [1,2,3,5]})

In [2]: df
Out[2]:
   A  B
0  5  1
1  6  2
2  3  3
3  4  5

In [3]: df[df['A'].isin([3, 6])]
Out[3]:
   A  B
1  6  2
2  3  3

And to get the opposite use ~:

In [4]: df[~df['A'].isin([3, 6])]
Out[4]:
   A  B
0  5  1
3  4  5

And just to be completely random for those who don't always want a black screen.

   self.tableView.tableHeaderView = segmentedControl; 

If you want it to obey your width and height properly though enclose your segmentedControl in a UIView first as the tableView likes to mangle your view a bit to fit the width.

This code crops an image from x=0,y=0 to h=100,w=200.

import numpy as np
import cv2

image = cv2.imread('download.jpg')
y=0
x=0
h=100
w=200
crop = image[y:y+h, x:x+w]
cv2.imshow('Image', crop)
cv2.waitKey(0) 

You can't use text as a background image, but you can use the :before or :after pseudo classes to place a text character where you want it, without having to add all kinds of messy extra mark-up.

Be sure to set position:relative on your actual text wrapper for the positioning to work.

.mytextwithicon {
    position:relative;
}    
.mytextwithicon:before {
    content: "\25AE";  /* this is your text. You can also use UTF-8 character codes as I do here */
    font-family: FontAwesome;
    left:-5px;
    position:absolute;
    top:0;
 }

EDIT:

Font Awesome v5 uses other font names than older versions:

• For FontAwesome v5, Free Version, use: font-family: "Font Awesome 5 Free"
• For FontAwesome v5, Pro Version, use: font-family: "Font Awesome 5 Pro"

Note that you should set the same font-weight property, too (seems to be 900).

Another way to find the font name is to right click on a sample font awesome icon on your page and get the font name (same way the utf-8 icon code can be found, but note that you can find it out on :before).

You don't need the assignment, list.append(x) will always append x to a and therefore there's no need te redefine a.

a = []
for i in range(5):    
    a.append(i)
print(a)

is all you need. This works because lists are mutable.

Also see the docs on data structures.

Os X Mojave 10.14 has:

Error: The Command Line Tools header package must be installed on Mojave.

Solution. Go to

/Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg

location and install the package manually. And brew will start working and we can run:

brew uninstall --force git
brew cleanup --force -s git
brew prune
brew install git

For an array of strings (but not an array of objects), you can check if an item exists by calling .indexOf() and if it doesn't then just push the item into the array:

var newItem = "NEW_ITEM_TO_ARRAY";_x000D_
var array = ["OLD_ITEM_1", "OLD_ITEM_2"];_x000D_
_x000D_
array.indexOf(newItem) === -1 ? array.push(newItem) : console.log("This item already exists");_x000D_
_x000D_
console.log(array)

There is no difference in working in both the concepts of assignment to unique_ptr.

int* intPtr = new int(3);
unique_ptr<int> uptr (intPtr);

is similar to

unique_ptr<int> uptr (new int(3));

Here unique_ptr automatically deletes the space occupied by uptr.

how pointers, declared in this way will be different from the pointers declared in a "normal" way.

If you create an integer in heap space (using new keyword or malloc), then you will have to clear that memory on your own (using delete or free respectively).

In the below code,

int* heapInt = new int(5);//initialize int in heap memory
.
.//use heapInt
.
delete heapInt;

Here, you will have to delete heapInt, when it is done using. If it is not deleted, then memory leakage occurs.

In order to avoid such memory leaks unique_ptr is used, where unique_ptr automatically deletes the space occupied by heapInt when it goes out of scope. So, you need not do delete or free for unique_ptr.

Try to use this

parseFloat().toFixed(2)

Actually, you need to update your repo first, then an upgrade of your Glibc can fix this issue.

The Firefox developer tools now does this. Events are shown by clicking the "ev" button on the right of each element's display, including jQuery and DOM events.

It's as simple as this :

$array[$key];

For me, Even after upgrading to appcompat-v7:22.1.0, in which AppCompatActivty is added, the problem was not resolved for me, Android Studio was giving same problem

Cannot resolve symbol 'AppCompatActivity'

Sometimes clearing the android studio caches help.

In android studio I just cleared the caches and restarted with the following option--

File->Invalidate Caches/Restart

Can someone please tell me how to create a static library from a .cpp and a .hpp file? Do I need to create the .o and the the .a?

Yes.

Create the .o (as per normal):

g++ -c header.cpp

Create the archive:

ar rvs header.a header.o

Test:

g++ test.cpp header.a -o executable_name

Note that it seems a bit pointless to make an archive with just one module in it. You could just as easily have written:

g++ test.cpp header.cpp -o executable_name

Still, I'll give you the benefit of the doubt that your actual use case is a bit more complex, with more modules.

Hope this helps!

It seems it is enough to restart the windows explorer service:

1. Open task manager
2. Find the Windows Explorer proces
3. Select it. After selection, the "Restart" button will appear in the bottom right corner.
4. Click the "restart" button. Windows explorer will be reloaded.

It helped in my case.

The following worked for me:

    }
}

And the factory itself as following:

@Service
public class MyServiceFactory {

    @Autowired
    private List<MyService> services;

    private static final Map<String, MyService> myServiceCache = new HashMap<>();

    @PostConstruct
    public void initMyServiceCache() {
        for(MyService service : services) {
            myServiceCache.put(service.getType(), service);
        }
    }

    public static MyService getService(String type) {
        MyService service = myServiceCache.get(type);
        if(service == null) throw new RuntimeException("Unknown service type: " + type);
        return service;
    }
}

I've found such implementation easier, cleaner and much more extensible. Adding new MyService is as easy as creating another spring bean implementing same interface without making any changes in other places.

I had the same issue and this helped me.

<ImageView
    android:id="@+id/image"
    android:layout_width="100dp"
    android:layout_height="100dp"
    android:scaleType="fitXY"
    />

Just try /s as listed below.

As the last line in the batch file type:

exit /s

The above command will close the Windows CMD window.

/s - stands for silent as in (it would wait for an input from the keyboard).

jQuery Library must be in the head section then.

<button onclick="var less = parseInt($('#qty').val()) - 1; $('#qty').val(less);"></button>
<input type="text" id="qty" value="2">
<button onclick="var add = parseInt($('#qty').val()) + 1; $('#qty').val(add);">+</button>

Fiddle of my solution is here. But just in case it expires I will paste the code as well.

HTML:

<select id="sel">
  <option value='1'>One</option>
  <option value='2'>Two</option>
  <option value='3'>Three</option>
</select>
<input type="button" id="button" value="Change option to 2" />

JS:

var sel = document.getElementById('sel'),
    button = document.getElementById('button');

button.addEventListener('click', function (e) {
    sel.options[1].selected = true;

    // firing the event properly according to StackOverflow
    // http://stackoverflow.com/questions/2856513/how-can-i-trigger-an-onchange-event-manually
    if ("createEvent" in document) {
        var evt = document.createEvent("HTMLEvents");
        evt.initEvent("change", false, true);
        sel.dispatchEvent(evt);
    }
    else {
        sel.fireEvent("onchange");
    }
});

sel.addEventListener('change', function (e) {
    alert('changed');
});

Another alternate approach to Diego's is to use a library:

https://github.com/airbnb/DeepLinkDispatch

You can easily declare the URIs you'd like to handle and the parameters you'd like to extract through annotations on the Activity, like:

@DeepLink("path/to/what/i/want")
public class SomeActivity extends Activity {
  ...
}

As a plus, the query parameters will also be passed along to the Activity as well.

This is a popular question. If you do not use these methods, the solution is updating the libraries. Please update your kotlin version, and all your dependencies like fabric, protobuf etc. If you are sure that you have updated everything, try asking the author of the library.

Tables work differently; sometimes counter-intuitively.

The solution is to use width on the table cells instead of max-width.

Although it may sound like in that case the cells won't shrink below the given width, they will actually.
with no restrictions on c, if you give the table a width of 70px, the widths of a, b and c will come out as 16, 42 and 12 pixels, respectively.
With a table width of 400 pixels, they behave like you say you expect in your grid above.
Only when you try to give the table too small a size (smaller than a.min+b.min+the content of C) will it fail: then the table itself will be wider than specified.

I made a snippet based on your fiddle, in which I removed all the borders and paddings and border-spacing, so you can measure the widths more accurately.

table {_x000D_
  width: 70px;_x000D_
}_x000D_
_x000D_
table, tbody, tr, td {_x000D_
  margin: 0;_x000D_
  padding: 0;_x000D_
  border: 0;_x000D_
  border-spacing: 0;_x000D_
}_x000D_
_x000D_
.a, .c {_x000D_
  background-color: red;_x000D_
}_x000D_
_x000D_
.b {_x000D_
  background-color: #F77;_x000D_
}_x000D_
_x000D_
.a {_x000D_
  min-width: 10px;_x000D_
  width: 20px;_x000D_
  max-width: 20px;_x000D_
}_x000D_
_x000D_
.b {_x000D_
  min-width: 40px;_x000D_
  width: 45px;_x000D_
  max-width: 45px;_x000D_
}_x000D_
_x000D_
.c {}

<table>_x000D_
  <tr>_x000D_
    <td class="a">A</td>_x000D_
    <td class="b">B</td>_x000D_
    <td class="c">C</td>_x000D_
  </tr>_x000D_
</table>

You can create your own JSONObject then toString().

Remember run it in the background thread like doInBackground in AsyncTask.

OkHttp version > 4:

// create your json here
JSONObject jsonObject = new JSONObject();
try {
    jsonObject.put("KEY1", "VALUE1");
    jsonObject.put("KEY2", "VALUE2");
} catch (JSONException e) {
    e.printStackTrace();
}

val client = OkHttpClient()
val mediaType = "application/json; charset=utf-8".toMediaType()
val body = jsonObject.toString().toRequestBody(mediaType)
val request: Request = Request.Builder()
            .url("https://YOUR_URL/")
            .post(body)
            .build()

var response: Response? = null
try {
    response = client.newCall(request).execute()
    val resStr = response.body!!.string()
} catch (e: IOException) {
    e.printStackTrace()
}
   

OkHttp version 3:

// create your json here
JSONObject jsonObject = new JSONObject();
try {
    jsonObject.put("KEY1", "VALUE1");
    jsonObject.put("KEY2", "VALUE2");
} catch (JSONException e) {
    e.printStackTrace();
}

  OkHttpClient client = new OkHttpClient();
  MediaType JSON = MediaType.parse("application/json; charset=utf-8");
  // put your json here
  RequestBody body = RequestBody.create(JSON, jsonObject.toString());
  Request request = new Request.Builder()
                    .url("https://YOUR_URL/")
                    .post(body)
                    .build();

  Response response = null;
  try {
      response = client.newCall(request).execute();
      String resStr = response.body().string();
  } catch (IOException e) {
      e.printStackTrace();
  }

sync and async file reading way:

//fs module to read file in sync and async way

var fs = require('fs'),
    filePath = './sample_files/sample_css.css';

// this for async way
/*fs.readFile(filePath, 'utf8', function (err, data) {
    if (err) throw err;
    console.log(data);
});*/

//this is sync way
var css = fs.readFileSync(filePath, 'utf8');
console.log(css);

Node Cheat Available at read_file.

If you keep track of the tail node, you don't need to loop through every element in the list.

Just update the tail to point to the new node:

AddValueToListEnd(value) {
    var node = new Node(value);

    if(!this.head) {
        this.head = node;
        this.tail = node;
    } else {
        this.tail.next = node; //point old tail to new node
    }
        
    this.tail = node; //now set the new node as the new tail
}

In plain English:

• Create a new node with the given value
• If the list is empty, point head and tail to the new node
• If the list is not empty, set the old tail.next to be the new node
• In either case, update the tail pointer to be the new node

Just use "\n" in your strings.xml file as below

<string name="relaxing_sounds">RELAXING\nSOUNDS</string>

Even if it doesn't looks 2 lines on layout actually it is 2 lines. Firstly you can check it on Translation Editor

Click the down button and you will see this image

Moreover if you run the app you will see that it is written in two lines.

I think you can use the nrows parameter. From the docs:

nrows : int, default None

    Number of rows of file to read. Useful for reading pieces of large files

which seems to work. Using one of the standard large test files (988504479 bytes, 5344499 lines):

In [1]: import pandas as pd

In [2]: time z = pd.read_csv("P00000001-ALL.csv", nrows=20)
CPU times: user 0.00 s, sys: 0.00 s, total: 0.00 s
Wall time: 0.00 s

In [3]: len(z)
Out[3]: 20

In [4]: time z = pd.read_csv("P00000001-ALL.csv")
CPU times: user 27.63 s, sys: 1.92 s, total: 29.55 s
Wall time: 30.23 s

A lot of responses on here are addressing the how but not the why. PHP $_SESSION key/value pairs are stored on the server. This differs from a cookie, which is stored on the browser. This is why you are able to access values in a cookie from both PHP and JavaScript. To make matters worse, AJAX requests from the browser do not include any of the cookies you have set for the website. So, you will have to make JavaScript pull the Session ID cookie and include it in every AJAX request for the server to be able to make heads or tails of it. On the bright side, PHP Sessions are designed to fail-over to a HTTP GET or POST variable if cookies are not sent along with the HTTP headers. I would look into some of the principles of RESTful web applications and use of of the design patterns that are common with those kinds of applications instead of trying to mangle with the session handler.

Assign a int -1 to an unsigned: As -1 does not fit in the range [0...UINT_MAX], multiples of UINT_MAX+1 are added until the answer is in range. Evidently UINT_MAX is pow(2,32)-1 or 429496725 on OP's machine so a has the value of 4294967295.

    unsigned int a = -1;

The "%x", "%u" specifier expects a matching unsigned. Since these do not match, "If a conversion specification is invalid, the behavior is undefined. If any argument is not the correct type for the corresponding conversion specification, the behavior is undefined." C11 §7.21.6.1 9. The printf specifier does not change b.

    printf("%x\n", b);  // UB
    printf("%u\n", b);  // UB

The "%d" specifier expects a matching int. Since these do not match, more UB.

    printf("%d\n", a);  // UB

Given undefined behavior, the conclusions are not supported.

both cases, the bytes are the same (ffffffff).

Even with the same bit pattern, different types may have different values. ffffffff as an unsigned has the value of 4294967295. As an int, depending signed integer encoding, it has the value of -1, -2147483647 or TBD. As a float it may be a NAN.

what is unsigned word for?

unsigned stores a whole number in the range [0 ... UINT_MAX]. It never has a negative value. If code needs a non-negative number, use unsigned. If code needs a counting number that may be +, - or 0, use int.

Update: to avoid a compiler warning about assigning a signed int to unsigned, use the below. This is an unsigned 1u being negated - which is well defined as above. The effect is the same as a -1, but conveys to the compiler direct intentions.

unsigned int a = -1u;

Another way is to use a website thumbnail/link preview service LinkPeek (even happens to show a screenshot of StackOverflow as a demo right now), URL2PNG, Browshot, Websnapr, or an alternative.

Java has two kind of Variables

a)
Class Level (Static) :
They are one per Class.Say you have Student Class and defined name as static variable.Now no matter how many student object you create all will have same name.

Object Level :
They belong to per Object.If name is non-static ,then all student can have different name.

b)
Class Level :
This variables are initialized on Class load.So even if no student object is created you can still access and use static name variable.

Object Level: They will get initialized when you create a new object ,say by new();

C)
Your Problem : Your class is Just loaded in JVM and you have called its main (static) method : Legally allowed.

Now from that you want to call an Object varibale : Where is the object ??

You have to create a Object and then only you can access Object level varibales.

Provided .wrapper is inside .item, and provided you're either not in IE 6 or .item is an a tag, the CSS you have should work just fine. Do you have evidence to suggest it isn't?

EDIT:

CSS alone can't affect something not contained within it. To make this happen, format your menu like so:

<ul class="menu">
    <li class="menuitem">
        <a href="destination">menu text</a>
        <ul class="menu">
            <li class="menuitem">
                <a href="destination">part of pull-out menu</a>
... etc ...

and your CSS like this:

.menu .menu {
    display: none;
}

.menu .menuitem:hover .menu {
    display: block;
    float: left;
    // likely need to set top & left
}

For Windows you can try below solution

Copy your gradle-->bin path and add it to system environment variable path.

In my case gradle path is

C:\Users\username\.gradle\wrapper\dists\gradle-3.3-all\55gk2rcmfc6p2dg9u9ohc3hw9\gradle-3.3\bin

This solution worked for me.

As an alternative, if you put a space between the date and time, DateTime.Parse will recognize the format for you. That's about as simple as you can get it. (If ParseExact was still not being recognized)

You can use Application class(public class in android.application package),that is:

Base class for those who need to maintain global application state. You can provide your own implementation by specifying its name in your AndroidManifest.xml's tag, which will cause that class to be instantiated for you when the process for your application/package is created.

To use this class do:

public class App extends Application {

    private static Context mContext;

    public static Context getContext() {
        return mContext;
    }

    public static void setContext(Context mContext) {
        this.mContext = mContext;
    }

    ...

}

In your manifest:

<application
        android:icon="..."
        android:label="..."
        android:name="com.example.yourmainpackagename.App" >
                       class that extends Application ^^^

In Activity B:

public class B extends Activity {

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.sampleactivitylayout);

        App.setContext(this);
                  ...
        }
...
}

In class A:

Context c = App.getContext();

Note:

There is normally no need to subclass Application. In most situation, static singletons can provide the same functionality in a more modular way. If your singleton needs a global context (for example to register broadcast receivers), the function to retrieve it can be given a Context which internally uses Context.getApplicationContext() when first constructing the singleton.

I've made an example for you showing how this could be done.

Notice the js but also that I changed #value into an input element

<input id="value" type="hidden" style="width:300px"/>

and that I am triggering the change event for getting the initial values

$('#attribute').select2().on('change', function() {
    $('#value').select2({data:data[$(this).val()]});
}).trigger('change');

Code Example

Edit:

In the current version of select2 the class attribute is being transferred from the hidden input into the root element created by select2, even the select2-offscreen class which positions the element way outside the page limits.

To fix this problem all that's needed is to add removeClass('select2-offscreen') before applying select2 a second time on the same element.

$('#attribute').select2().on('change', function() {
    $('#value').removeClass('select2-offscreen').select2({data:data[$(this).val()]});
}).trigger('change');

I've added a new Code Example to address this issue.

Range("A1").value = Environ("Username")

This is better than Application.Username, which doesn't always supply the Windows username. Thanks to Kyle for pointing this out.

• Application Username is the name of the User set in Excel > Tools > Options
• Environ("Username") is the name you registered for Windows; see Control Panel >System

You can also do it by toggling between display: block on hover and display:none without hover to produce the effect.

The difference appears when the special parameters are quoted. Let me illustrate the differences:

$ set -- "arg  1" "arg  2" "arg  3"

$ for word in $*; do echo "$word"; done
arg
1
arg
2
arg
3

$ for word in $@; do echo "$word"; done
arg
1
arg
2
arg
3

$ for word in "$*"; do echo "$word"; done
arg  1 arg  2 arg  3

$ for word in "$@"; do echo "$word"; done
arg  1
arg  2
arg  3

one further example on the importance of quoting: note there are 2 spaces between "arg" and the number, but if I fail to quote $word:

$ for word in "$@"; do echo $word; done
arg 1
arg 2
arg 3

and in bash, "$@" is the "default" list to iterate over:

$ for word; do echo "$word"; done
arg  1
arg  2
arg  3

<button type="button" href="location.href='#/nameOfState'">Title on button</button>

Even more simple... (note the single quotes around the address)

If you are just looking for the text which you can then split up but don't want to use the API take a look at en.wikipedia.org/w/index.php?title=Elephant&action=raw

In ES6, you can do:

const objArray = [{foo: 1, bar: 2}, {foo: 3, bar: 4}, {foo: 5, bar: 6}]
objArray.map(({ foo }) => foo)

This falls into workaround category, containing some extra information too:

Since the notifications are handled differently depending on the state of the app (foreground/background/not launched) I've seen the best way to implement a helper class where the selected activity is launched based on the custom data sent in the notification message.

• when the app is on foreground use the helper class in onMessageReceived
• when the app is on background use the helper class for handling the intent in main activity's onNewIntent (check for specific custom data)
• when the app is not running use the helper class for handling the intent in main activity's onCreate (call getIntent for the intent).

This way you do not need the click_action or intent filter specific to it. Also you write the code just once and can reasonably easily start any activity.

So the minimum custom data would look something like this:

Key: run_activity
Value: com.mypackage.myactivity

And the code for handling it:

if (intent.hasExtra("run_activity")) {
    handleFirebaseNotificationIntent(intent);
}


private void handleFirebaseNotificationIntent(Intent intent){
    String className = intent.getStringExtra("run_activity");
    startSelectedActivity(className, intent.getExtras());
}

private void startSelectedActivity(String className, Bundle extras){
    Class cls;
    try {
        cls = Class.forName(className);
    }catch(ClassNotFoundException e){
        ...
    }
    Intent i = new Intent(context, cls);

    if (i != null) {
        i.putExtras(extras);
        this.startActivity(i);
    } 
}

That is the code for the last two cases, startSelectedActivity would be called also from onMessageReceived (first case).

The limitation is that all the data in the intent extras are strings, so you may need to handle that somehow in the activity itself. Also, this is simplified, you probably don't what to change the Activity/View on an app that is on the foreground without warning your user.

tx, found the workaround I needed:

  constructor(private zone:NgZone) {
    // enable to for time travel
    this.appStore.subscribe((state) => {
        this.zone.run(() => {
            console.log('enabled time travel');
        });
    });

running zone.run will force the component to re-render

Anyone searching for this might find the following extension method useful:

public static class TypeExtensions
{
    public static bool ImplementsInterface(this Type type, Type @interface)
    {
        if (type == null)
        {
            throw new ArgumentNullException(nameof(type));
        }

        if (@interface == null)
        {
            throw new ArgumentNullException(nameof(@interface));
        }

        var interfaces = type.GetInterfaces();
        if (@interface.IsGenericTypeDefinition)
        {
            foreach (var item in interfaces)
            {
                if (item.IsConstructedGenericType && item.GetGenericTypeDefinition() == @interface)
                {
                    return true;
                }
            }
        }
        else
        {
            foreach (var item in interfaces)
            {
                if (item == @interface)
                {
                    return true;
                }
            }
        }

        return false;
    }
}

xunit tests:

To complete the list of possible alternatives, reduce could be used to implement the behavior of flatten:

var a = ["a", "b", "c"] 
var b = ["d", "e", "f"]

let res = [a, b].reduce([],combine:+)

The best alternative (performance/memory-wise) among the ones presented is simply flatten, that just wrap the original arrays lazily without creating a new array structure.

But notice that flatten does not return a LazyCollection, so that lazy behavior will not be propagated to the next operation along the chain (map, flatMap, filter, etc...).

If lazyness makes sense in your particular case, just remember to prepend or append a .lazy to flatten(), for example, modifying Tomasz sample this way:

let c = [a, b].lazy.flatten()

I found this command more straightforward:

for p in $(kubectl get pods | grep Terminating | awk '{print $1}'); do kubectl delete pod $p --grace-period=0 --force;done

It will delete all pods in Terminating status in default namespace.

This error is probably related to a byte order mark (BOM) prior to the actual XML content. You need to parse the returned String and discard the BOM, so SAXParser can process the document correctly.

You will find a possible solution here.

Well, it's not a single statement, but it's about as close as you can get with oracle:

BEGIN
   FOR R IN (SELECT owner, table_name FROM all_tables WHERE owner='TheOwner') LOOP
      EXECUTE IMMEDIATE 'grant select on '||R.owner||'.'||R.table_name||' to TheUser';
   END LOOP;
END; 

You can try also using below script

<html>
<head>
<script>
function load()
{
document.frm1.submit()
}
</script>
</head>

<body onload="load()">
<form action="http://www.google.com" id="frm1" name="frm1">
<input type="text" value="" />
</form>
</body>
</html> 

I don't recommend Pear Mail. It has not been updated since 2010. Also read the source files; the source code is almost outdated, written in PHP 4 style and many errors / bugs have been posted (Google it). I am using Swift Mailer.

Swift Mailer integrates into any web application written in PHP 5, offering a flexible and elegant object-oriented approach to sending emails with a multitude of features.

Send emails using SMTP, sendmail, postfix or a custom Transport implementation of your own.

Support servers that require username & password and/or encryption.

Protect from header injection attacks without stripping request data content.

Send MIME compliant HTML/multipart emails.

Use event-driven plugins to customize the library.

Handle large attachments and inline/embedded images with low memory use.

It is a free and open source you can Download Swift Mailer and upload to your server. (The feature list is copied from owner website).

The working example of Gmail SSL/SMTP and Swift Mailer is here...

// Swift Mailer Library
require_once '../path/to/lib/swift_required.php';

// Mail Transport
$transport = Swift_SmtpTransport::newInstance('ssl://smtp.gmail.com', 465)
    ->setUsername('[email protected]') // Your Gmail Username
    ->setPassword('my_secure_gmail_password'); // Your Gmail Password

// Mailer
$mailer = Swift_Mailer::newInstance($transport);

// Create a message
$message = Swift_Message::newInstance('Wonderful Subject Here')
    ->setFrom(array('[email protected]' => 'Sender Name')) // can be $_POST['email'] etc...
    ->setTo(array('[email protected]' => 'Receiver Name')) // your email / multiple supported.
    ->setBody('Here is the <strong>message</strong> itself. It can be text or <h1>HTML</h1>.', 'text/html');

// Send the message
if ($mailer->send($message)) {
    echo 'Mail sent successfully.';
} else {
    echo 'I am sure, your configuration are not correct. :(';
}

I hope this helps. Happy coding... :)

you can use update from...

something like:

update shipment set.... from shipment inner join ProfilerTest.dbo.BookingDetails on ...

#map_canvas {
   width: 100%;
}

JS

// On Resize
$(window).resize(function(){ 
    $('#map_canvas').height($( window ).height());

In appdelegate.m file write the follwing code in applicationDidEnterBackground to get the local notification

- (void)applicationDidEnterBackground:(UIApplication *)application
{
   UILocalNotification *notification = [[UILocalNotification alloc]init];
   notification.repeatInterval = NSDayCalendarUnit;
   [notification setAlertBody:@"Hello world"];
   [notification setFireDate:[NSDate dateWithTimeIntervalSinceNow:1]];
   [notification setTimeZone:[NSTimeZone  defaultTimeZone]];
   [application setScheduledLocalNotifications:[NSArray arrayWithObject:notification]];
}

Converting of a hash map to a string of query parameters:

Map<String, String> params = new HashMap<>();
params.put("msisdn", msisdn);
params.put("email", email);
params.put("clientVersion", clientVersion);
params.put("clientType", clientType);
params.put("issuerName", issuerName);
params.put("applicationName", applicationName);

UriComponentsBuilder builder = UriComponentsBuilder.fromHttpUrl(url);
for (Map.Entry<String, String> entry : params.entrySet()) {
    builder.queryParam(entry.getKey(), entry.getValue());
}

HttpHeaders headers = new HttpHeaders();
headers.set("Accept", "application/json");

HttpEntity<String> response = restTemplate.exchange(builder.toUriString(), HttpMethod.GET, new HttpEntity(headers), String.class);

This is very much implementation specific, but the general idea is to allow providers to issue short term access tokens with long term refresh tokens. Why?

• Many providers support bearer tokens which are very weak security-wise. By making them short-lived and requiring refresh, they limit the time an attacker can abuse a stolen token.
• Large scale deployment don't want to perform a database lookup every API call, so instead they issue self-encoded access token which can be verified by decryption. However, this also means there is no way to revoke these tokens so they are issued for a short time and must be refreshed.
• The refresh token requires client authentication which makes it stronger. Unlike the above access tokens, it is usually implemented with a database lookup.

Ok to answer this . I simply converted my < and the > to < and >. What was happening previously is i used to set the text <script>alert('1')</script> but before setting the text in the input text browserconverts < and > as < and the >. So hence converting them again to < and >since browser will understand that as only tags and converts them , than executing the script inside <input type="text" />

we had similar header issue with Amazon (AWS) S3 presigned Post failing on some browsers.

point was to tell bucket CORS to expose header <ExposeHeader>Access-Control-Allow-Origin</ExposeHeader>

A lot of student exercises use Scanner because it has a variety of methods to parse numbers. I usually just start with an idiomatic line-oriented filter:

import java.io.*;

public class FilterLine {

    public static void main(String[] args) throws IOException {
        BufferedReader in = new BufferedReader(
            new InputStreamReader(System.in));
        String s;

        while ((s = in.readLine()) != null) {
            System.out.println(s);
        }
    }
}

The full procedure that worked for me to transfer ALL branches and tags is, combining the answers of @vikas027 and @kumarahul:

~$ git clone <url_of_old_repo>
~$ cd <name_of_old_repo>
~$ git remote add new-origin <url_of_new_repo>
~$ git push new-origin --mirror
~$ git push new-origin refs/remotes/origin/*:refs/heads/*
~$ git push new-origin --delete HEAD

The last step is because a branch named HEAD appears in the new remote due to the wildcard

The easiest way to avoid suck kind of error is:

-Change library combilesdkversion as same as your app compilesdkversion

-Change library's supportLibrary version as same as your build.gradle(app)

If you're getting a lot of warnings (in my case 64 in a solution!) like

CS0618: 'ConfigurationSettings.AppSettings' is obsolete: 'This method is obsolete, it has been replaced by System.Configuration!System.Configuration.ConfigurationManager.AppSettings'

because you're upgrading an older project you can save a lot of time as follows:

1. Add System.Configuration as a reference to your References section.

2. Add the following two using statements to the top of each class (.cs) file:

   using System.Configuration; using ConfigurationSettings = System.Configuration.ConfigurationManager;

By this change all occurances of

ConfigurationSettings.AppSettings["mySetting"]

will now reference the right configuration manager, no longer the deprecated one, and all the CS0618 warnings will go away immediately.

Of course, keep in mind that this is a quick hack. On the long term, you should consider refactoring the code.

I found that onSaveInstanceState is always called when another Activity comes to the foreground. And so is onStop.

However, onRestoreInstanceState was called only when onCreate and onStart were also called. And, onCreate and onStart were NOT always called.

So it seems like Android doesn't always delete the state information even if the Activity moves to the background. However, it calls the lifecycle methods to save state just to be safe. Thus, if the state is not deleted, then Android doesn't call the lifecycle methods to restore state as they are not needed.

Figure 2 describes this.

I tried researching that too but instead ended up using jsconsole.com by Remy Sharp (he also created jsbin.com). I'm running on Ubuntu 12.10 so I had to create a special icon but if you're on Windows and use Chrome simply go to Tools>Create Application Shortcuts (note this doesn't work very well, or at all in my case, on Ubuntu). This site works very like the Mac jsc console: actually it has some cool features too (like loading libraries/code from a URL) that I guess jsc does not.

Hope this helps.

You can do like this:

Sub Get_Environmental_Variable()

Dim sHostName As String
Dim sUserName As String

' Get Host Name / Get Computer Name    
sHostName = Environ$("computername")

' Get Current User Name    
sUserName = Environ$("username")

End Sub

Well,

Just worked it out. While having both installations we have two ORACLE_HOME directories and both have SQAORA32.dll files. While looking up for ORACLE_HOMe my app was getting confused..I just removed the Client oracle home entry as oracle client is by default present in oracle DB Now its working...Thanks!!

(Update on May 28, 2016) Using RealGUD in Emacs

For anyone in Emacs, this thread shows how to accomplish everything described in the OP (and more) using

1. a new important debugger in Emacs called RealGUD which can operate with any debugger (including ipdb).
2. The Emacs package isend-mode.

The combination of these two packages is extremely powerful and allows one to recreate exactly the behavior described in the OP and do even more.

More info on the wiki article of RealGUD for ipdb.

Original answer:

After having tried many different methods for debugging Python, including everything mentioned in this thread, one of my preferred ways of debugging Python with IPython is with embedded shells.

Defining a custom embedded IPython shell:

Add the following on a script to your PYTHONPATH, so that the method ipsh() becomes available.

import inspect

# First import the embed function
from IPython.terminal.embed import InteractiveShellEmbed
from IPython.config.loader import Config

# Configure the prompt so that I know I am in a nested (embedded) shell
cfg = Config()
prompt_config = cfg.PromptManager
prompt_config.in_template = 'N.In <\\#>: '
prompt_config.in2_template = '   .\\D.: '
prompt_config.out_template = 'N.Out<\\#>: '

# Messages displayed when I drop into and exit the shell.
banner_msg = ("\n**Nested Interpreter:\n"
"Hit Ctrl-D to exit interpreter and continue program.\n"
"Note that if you use %kill_embedded, you can fully deactivate\n"
"This embedded instance so it will never turn on again")   
exit_msg = '**Leaving Nested interpreter'

# Wrap it in a function that gives me more context:
def ipsh():
    ipshell = InteractiveShellEmbed(config=cfg, banner1=banner_msg, exit_msg=exit_msg)

    frame = inspect.currentframe().f_back
    msg   = 'Stopped at {0.f_code.co_filename} at line {0.f_lineno}'.format(frame)

    # Go back one level! 
    # This is needed because the call to ipshell is inside the function ipsh()
    ipshell(msg,stack_depth=2)

Then, whenever I want to debug something in my code, I place ipsh() right at the location where I need to do object inspection, etc. For example, say I want to debug my_function below

Using it:

def my_function(b):
  a = b
  ipsh() # <- This will embed a full-fledged IPython interpreter
  a = 4

and then I invoke my_function(2) in one of the following ways:

1. Either by running a Python program that invokes this function from a Unix shell
2. Or by invoking it directly from IPython

Regardless of how I invoke it, the interpreter stops at the line that says ipsh(). Once you are done, you can do Ctrl-D and Python will resume execution (with any variable updates that you made). Note that, if you run the code from a regular IPython the IPython shell (case 2 above), the new IPython shell will be nested inside the one from which you invoked it, which is perfectly fine, but it's good to be aware of. Eitherway, once the interpreter stops on the location of ipsh, I can inspect the value of a (which be 2), see what functions and objects are defined, etc.

The problem:

The solution above can be used to have Python stop anywhere you want in your code, and then drop you into a fully-fledged IPython interpreter. Unfortunately it does not let you add or remove breakpoints once you invoke the script, which is highly frustrating. In my opinion, this is the only thing that is preventing IPython from becoming a great debugging tool for Python.

The best you can do for now:

A workaround is to place ipsh() a priori at the different locations where you want the Python interpreter to launch an IPython shell (i.e. a breakpoint). You can then "jump" between different pre-defined, hard-coded "breakpoints" with Ctrl-D, which would exit the current embedded IPython shell and stop again whenever the interpreter hits the next call to ipsh().

If you go this route, one way to exit "debugging mode" and ignore all subsequent breakpoints, is to use ipshell.dummy_mode = True which will make Python ignore any subsequent instantiations of the ipshell object that we created above.

I know this question is over 6 years old, but still, I would like to share my method using tables and this won't require any CSS.

<table><tr><td><img src="loading.gif"></td><td> Loading...</td></tr></table>

Cheers! Happy Coding

    })

It's not a good coding to put PHP code into CSS

body
{
    background-image:url('bg.png');
}

that's it

Or if you have an array of [key, value] arrays, you can do:

[[1, 2], [3, 4]].inject({}) do |r, s|
  r.merge!({s[0] => s[1]})
end # => { 1 => 2, 3 => 4 }

Using the first for-loop you manually enumerate through the array by increasing an index to the length of the array, then getting the value at the current index manually.

The latter syntax is added in Java 5 and enumerates an array by using an Iterator instance under the hoods. You then have only access to the object (not the index) and you won't be able to adjust the array while enumerating.

It's convenient when you just want to perform some actions on all objects in an array.

I find it easier using this formula

=IF(B2<>"",TEXT(ROW(A1),"IR-0000"),"")

Need to paste this formula at A2, that means when you are encoding data at B cell the A cell will automatically input the serial code and when there's no data the cell will stay blank....you can change the "IR" to any first letter code you want to be placed in your row.

Hope it helps

If you are looking for readability, I believe that this is that code:

print '%(kg).2f kg = %(lb).2f lb = %(gal).2f gal = %(l).2f l' % {
    'kg': var1,
    'lb': var2,
    'gal': var3,
    'l': var4,
}

Add the column and update all rows in the DataTable, for example:

DataTable tbl = new DataTable();
tbl.Columns.Add(new DataColumn("ID", typeof(Int32)));
tbl.Columns.Add(new DataColumn("Name", typeof(string)));
for (Int32 i = 1; i <= 10; i++) {
    DataRow row = tbl.NewRow();
    row["ID"] = i;
    row["Name"] = i + ". row";
    tbl.Rows.Add(row);
}
DataColumn newCol = new DataColumn("NewColumn", typeof(string));
newCol.AllowDBNull = true;
tbl.Columns.Add(newCol);
foreach (DataRow row in tbl.Rows) {
    row["NewColumn"] = "You DropDownList value";
}
//if you don't want to allow null-values'
newCol.AllowDBNull = false;

simple and easy solution to create splash screen

1. open new form use name "SPLASH"
2. change background image whatever you want
3. select progress bar
4. select timer

now set timer tick in timer:

private void timer1_Tick(object sender, EventArgs e)
{
    progressBar1.Increment(1);
    if (progressBar1.Value == 100) timer1.Stop();        
}

add new form use name "FORM-1"and use following command in FORM 1.

note: Splash form works before opening your form1

1. add this library

   using System.Threading;
   

2. create function

   public void splash()
   {     
       Application.Run(new splash());
   }
   

3. use following command in initialization like below.

   public partial class login : Form
   {     
       public login()
       {
           Thread t = new Thread(new ThreadStart(splash));
           t.Start();
           Thread.Sleep(15625);
   
           InitializeComponent();
   
           enter code here
   
           t.Abort();
       }
   }

Yes, should try reinstall mysql, but use the --reinstall flag to force a package reconfiguration. So the operating system service configuration is not skipped:

sudo apt --reinstall install mysql-server

I think that without using -exec you can simply provide /dev/null as at least one argument in case nothing is found:

grep -rl oldstr path | xargs sed -i 's/oldstr/newstr/g' /dev/null

Used to face the same problem. The reason was in incorrect context passing to AlertDialog.Builder(here). use like AlertDialog.Builder(Homeactivity.this)

I don't think you need a case statement. You just need to update your where clause and make sure you have correct parentheses to group the clauses.

SELECT Sum(CAMount) as PaymentAmount 
from TableOrderPayment 
where (CStatus = 'Active' AND CPaymentType = 'Cash') 
OR (CStatus = 'Active' and CPaymentType = 'Check' and CDate<=SYSDATETIME())

The answers posted before mine assume that CDate<=SYSDATETIME() is also appropriate for Cash payment type as well. I think I split mine out so it only looks for that clause for check payments.

Here is how I do it. You will need to get the namespace URL and the element name from your generated code.

new JAXBElement(new QName("http://www.novell.com/role/service","userDN"),
                new String("").getClass(),testDN);

Try adding the following middleware to your NodeJS/Express app (I have added some comments for your convenience):

// Add headers
app.use(function (req, res, next) {

    // Website you wish to allow to connect
    res.setHeader('Access-Control-Allow-Origin', 'http://localhost:8888');

    // Request methods you wish to allow
    res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');

    // Request headers you wish to allow
    res.setHeader('Access-Control-Allow-Headers', 'X-Requested-With,content-type');

    // Set to true if you need the website to include cookies in the requests sent
    // to the API (e.g. in case you use sessions)
    res.setHeader('Access-Control-Allow-Credentials', true);

    // Pass to next layer of middleware
    next();
});

Hope that helps!

I know the question specifies Excel, but since the same question for Access got marked as duplicate, so I will post my answer here. The principle is simple: open a new Access application, then open a form with a timer inside that application, send the function/sub you want to execute to that form, execute the task if the timer hits, and quit the application once execution has finished. This allows the VBA to work with tables and queries from your database. Note: it will throw errors if you've exclusively locked the database.

This is all VBA (as opposed to other answers)

The function that runs a sub/function asynchronously

Public Sub RunFunctionAsync(FunctionName As String)
    Dim A As Access.Application
    Set A = New Access.Application
    A.OpenCurrentDatabase Application.CurrentProject.FullName
    A.DoCmd.OpenForm "MultithreadingEngine"
    With A.Forms("MultiThreadingEngine")
        .TimerInterval = 10
        .AddToTaskCollection (FunctionName)
    End With
End Sub

The module of the form required to achieve this

(form name = MultiThreadingEngine, doesn't have any controls or properties set)

Public TaskCollection As Collection

Public Sub AddToTaskCollection(str As String)
    If TaskCollection Is Nothing Then
        Set TaskCollection = New Collection
    End If
    TaskCollection.Add str
End Sub
Private Sub Form_Timer()
    If Not TaskCollection Is Nothing Then
        If TaskCollection.Count <> 0 Then
            Dim CollectionItem As Variant
            For Each CollectionItem In TaskCollection
                Run CollectionItem
            Next CollectionItem
        End If
    End If
    Application.Quit
End Sub

Implementing support for parameters should be easy enough, returning values is difficult, however.

?:

1. Set your PERL_UNICODE envariable to AS. This makes all Perl scripts decode @ARGV as UTF-8 strings, and sets the encoding of all three of stdin, stdout, and stderr to UTF-8. Both these are global effects, not lexical ones.

2. At the top of your source file (program, module, library, dohickey), prominently assert that you are running perl version 5.12 or better via:

   use v5.12;  # minimal for unicode string feature
   use v5.14;  # optimal for unicode string feature
   

3. Enable warnings, since the previous declaration only enables strictures and features, not warnings. I also suggest promoting Unicode warnings into exceptions, so use both these lines, not just one of them. Note however that under v5.14, the utf8 warning class comprises three other subwarnings which can all be separately enabled: nonchar, surrogate, and non_unicode. These you may wish to exert greater control over.

   use warnings;
   use warnings qw( FATAL utf8 );
   

4. Declare that this source unit is encoded as UTF-8. Although once upon a time this pragma did other things, it now serves this one singular purpose alone and no other:

   use utf8;
   

5. Declare that anything that opens a filehandle within this lexical scope but not elsewhere is to assume that that stream is encoded in UTF-8 unless you tell it otherwise. That way you do not affect other module’s or other program’s code.

   use open qw( :encoding(UTF-8) :std );
   

6. Enable named characters via \N{CHARNAME}.

   use charnames qw( :full :short );
   

7. If you have a DATA handle, you must explicitly set its encoding. If you want this to be UTF-8, then say:

   binmode(DATA, ":encoding(UTF-8)");
   

There is of course no end of other matters with which you may eventually find yourself concerned, but these will suffice to approximate the state goal to “make everything just work with UTF-8”, albeit for a somewhat weakened sense of those terms.

One other pragma, although it is not Unicode related, is:

      use autodie;

It is strongly recommended.

? ?

My own boilerplate these days tends to look like this:

use 5.014;

use utf8;
use strict;
use autodie;
use warnings; 
use warnings    qw< FATAL  utf8     >;
use open        qw< :std  :utf8     >;
use charnames   qw< :full >;
use feature     qw< unicode_strings >;

use File::Basename      qw< basename >;
use Carp                qw< carp croak confess cluck >;
use Encode              qw< encode decode >;
use Unicode::Normalize  qw< NFD NFC >;

END { close STDOUT }

if (grep /\P{ASCII}/ => @ARGV) { 
   @ARGV = map { decode("UTF-8", $_) } @ARGV;
}

$0 = basename($0);  # shorter messages
$| = 1;

binmode(DATA, ":utf8");

# give a full stack dump on any untrapped exceptions
local $SIG{__DIE__} = sub {
    confess "Uncaught exception: @_" unless $^S;
};

# now promote run-time warnings into stack-dumped
#   exceptions *unless* we're in an try block, in
#   which case just cluck the stack dump instead
local $SIG{__WARN__} = sub {
    if ($^S) { cluck   "Trapped warning: @_" } 
    else     { confess "Deadly warning: @_"  }
};

while (<>)  {
    chomp;
    $_ = NFD($_);
    ...
} continue {
    say NFC($_);
}

__END__

Saying that “Perl should [somehow!] enable Unicode by default” doesn’t even start to begin to think about getting around to saying enough to be even marginally useful in some sort of rare and isolated case. Unicode is much much more than just a larger character repertoire; it’s also how those characters all interact in many, many ways.

Even the simple-minded minimal measures that (some) people seem to think they want are guaranteed to miserably break millions of lines of code, code that has no chance to “upgrade” to your spiffy new Brave New World modernity.

It is way way way more complicated than people pretend. I’ve thought about this a huge, whole lot over the past few years. I would love to be shown that I am wrong. But I don’t think I am. Unicode is fundamentally more complex than the model that you would like to impose on it, and there is complexity here that you can never sweep under the carpet. If you try, you’ll break either your own code or somebody else’s. At some point, you simply have to break down and learn what Unicode is about. You cannot pretend it is something it is not.

goes out of its way to make Unicode easy, far more than anything else I’ve ever used. If you think this is bad, try something else for a while. Then come back to : either you will have returned to a better world, or else you will bring knowledge of the same with you so that we can make use of your new knowledge to make better at these things.

?

At a minimum, here are some things that would appear to be required for to “enable Unicode by default”, as you put it:

1. All source code should be in UTF-8 by default. You can get that with use utf8 or export PERL5OPTS=-Mutf8.

2. The DATA handle should be UTF-8. You will have to do this on a per-package basis, as in binmode(DATA, ":encoding(UTF-8)").

3. Program arguments to scripts should be understood to be UTF-8 by default. export PERL_UNICODE=A, or perl -CA, or export PERL5OPTS=-CA.

4. The standard input, output, and error streams should default to UTF-8. export PERL_UNICODE=S for all of them, or I, O, and/or E for just some of them. This is like perl -CS.

5. Any other handles opened by should be considered UTF-8 unless declared otherwise; export PERL_UNICODE=D or with i and o for particular ones of these; export PERL5OPTS=-CD would work. That makes -CSAD for all of them.

6. Cover both bases plus all the streams you open with export PERL5OPTS=-Mopen=:utf8,:std. See uniquote.

7. You don’t want to miss UTF-8 encoding errors. Try export PERL5OPTS=-Mwarnings=FATAL,utf8. And make sure your input streams are always binmoded to :encoding(UTF-8), not just to :utf8.

8. Code points between 128–255 should be understood by to be the corresponding Unicode code points, not just unpropertied binary values. use feature "unicode_strings" or export PERL5OPTS=-Mfeature=unicode_strings. That will make uc("\xDF") eq "SS" and "\xE9" =~ /\w/. A simple export PERL5OPTS=-Mv5.12 or better will also get that.

9. Named Unicode characters are not by default enabled, so add export PERL5OPTS=-Mcharnames=:full,:short,latin,greek or some such. See uninames and tcgrep.

10. You almost always need access to the functions from the standard Unicode::Normalize module various types of decompositions. export PERL5OPTS=-MUnicode::Normalize=NFD,NFKD,NFC,NFKD, and then always run incoming stuff through NFD and outbound stuff from NFC. There’s no I/O layer for these yet that I’m aware of, but see nfc, nfd, nfkd, and nfkc.

11. String comparisons in using eq, ne, lc, cmp, sort, &c&cc are always wrong. So instead of @a = sort @b, you need @a = Unicode::Collate->new->sort(@b). Might as well add that to your export PERL5OPTS=-MUnicode::Collate. You can cache the key for binary comparisons.

12. built-ins like printf and write do the wrong thing with Unicode data. You need to use the Unicode::GCString module for the former, and both that and also the Unicode::LineBreak module as well for the latter. See uwc and unifmt.

13. If you want them to count as integers, then you are going to have to run your \d+ captures through the Unicode::UCD::num function because ’s built-in atoi(3) isn’t currently clever enough.

14. You are going to have filesystem issues on filesystems. Some filesystems silently enforce a conversion to NFC; others silently enforce a conversion to NFD. And others do something else still. Some even ignore the matter altogether, which leads to even greater problems. So you have to do your own NFC/NFD handling to keep sane.

15. All your code involving a-z or A-Z and such MUST BE CHANGED, including m//, s///, and tr///. It’s should stand out as a screaming red flag that your code is broken. But it is not clear how it must change. Getting the right properties, and understanding their casefolds, is harder than you might think. I use unichars and uniprops every single day.

16. Code that uses \p{Lu} is almost as wrong as code that uses [A-Za-z]. You need to use \p{Upper} instead, and know the reason why. Yes, \p{Lowercase} and \p{Lower} are different from \p{Ll} and \p{Lowercase_Letter}.

17. Code that uses [a-zA-Z] is even worse. And it can’t use \pL or \p{Letter}; it needs to use \p{Alphabetic}. Not all alphabetics are letters, you know!

18. If you are looking for variables with /[\$\@\%]\w+/, then you have a problem. You need to look for /[\$\@\%]\p{IDS}\p{IDC}*/, and even that isn’t thinking about the punctuation variables or package variables.

19. If you are checking for whitespace, then you should choose between \h and \v, depending. And you should never use \s, since it DOES NOT MEAN [\h\v], contrary to popular belief.

20. If you are using \n for a line boundary, or even \r\n, then you are doing it wrong. You have to use \R, which is not the same!

21. If you don’t know when and whether to call Unicode::Stringprep, then you had better learn.

22. Case-insensitive comparisons need to check for whether two things are the same letters no matter their diacritics and such. The easiest way to do that is with the standard Unicode::Collate module. Unicode::Collate->new(level => 1)->cmp($a, $b). There are also eq methods and such, and you should probably learn about the match and substr methods, too. These are have distinct advantages over the built-ins.

23. Sometimes that’s still not enough, and you need the Unicode::Collate::Locale module instead, as in Unicode::Collate::Locale->new(locale => "de__phonebook", level => 1)->cmp($a, $b) instead. Consider that Unicode::Collate::->new(level => 1)->eq("d", "ð") is true, but Unicode::Collate::Locale->new(locale=>"is",level => 1)->eq("d", " ð") is false. Similarly, "ae" and "æ" are eq if you don’t use locales, or if you use the English one, but they are different in the Icelandic locale. Now what? It’s tough, I tell you. You can play with ucsort to test some of these things out.

24. Consider how to match the pattern CVCV (consonsant, vowel, consonant, vowel) in the string “niño”. Its NFD form — which you had darned well better have remembered to put it in — becomes “nin\x{303}o”. Now what are you going to do? Even pretending that a vowel is [aeiou] (which is wrong, by the way), you won’t be able to do something like (?=[aeiou])\X) either, because even in NFD a code point like ‘ø’ does not decompose! However, it will test equal to an ‘o’ using the UCA comparison I just showed you. You can’t rely on NFD, you have to rely on UCA.

And that’s not all. There are a million broken assumptions that people make about Unicode. Until they understand these things, their code will be broken.

1. Code that assumes it can open a text file without specifying the encoding is broken.

2. Code that assumes the default encoding is some sort of native platform encoding is broken.

3. Code that assumes that web pages in Japanese or Chinese take up less space in UTF-16 than in UTF-8 is wrong.

4. Code that assumes Perl uses UTF-8 internally is wrong.

5. Code that assumes that encoding errors will always raise an exception is wrong.

6. Code that assumes Perl code points are limited to 0x10_FFFF is wrong.

7. Code that assumes you can set $/ to something that will work with any valid line separator is wrong.

8. Code that assumes roundtrip equality on casefolding, like lc(uc($s)) eq $s or uc(lc($s)) eq $s, is completely broken and wrong. Consider that the uc("s") and uc("?") are both "S", but lc("S") cannot possibly return both of those.

9. Code that assumes every lowercase code point has a distinct uppercase one, or vice versa, is broken. For example, "ª" is a lowercase letter with no uppercase; whereas both "?" and "?" are letters, but they are not lowercase letters; however, they are both lowercase code points without corresponding uppercase versions. Got that? They are not \p{Lowercase_Letter}, despite being both \p{Letter} and \p{Lowercase}.

10. Code that assumes changing the case doesn’t change the length of the string is broken.

11. Code that assumes there are only two cases is broken. There’s also titlecase.

12. Code that assumes only letters have case is broken. Beyond just letters, it turns out that numbers, symbols, and even marks have case. In fact, changing the case can even make something change its main general category, like a \p{Mark} turning into a \p{Letter}. It can also make it switch from one script to another.

13. Code that assumes that case is never locale-dependent is broken.

14. Code that assumes Unicode gives a fig about POSIX locales is broken.

15. Code that assumes you can remove diacritics to get at base ASCII letters is evil, still, broken, brain-damaged, wrong, and justification for capital punishment.

16. Code that assumes that diacritics \p{Diacritic} and marks \p{Mark} are the same thing is broken.

17. Code that assumes \p{GC=Dash_Punctuation} covers as much as \p{Dash} is broken.

18. Code that assumes dash, hyphens, and minuses are the same thing as each other, or that there is only one of each, is broken and wrong.

19. Code that assumes every code point takes up no more than one print column is broken.

20. Code that assumes that all \p{Mark} characters take up zero print columns is broken.

21. Code that assumes that characters which look alike are alike is broken.

22. Code that assumes that characters which do not look alike are not alike is broken.

23. Code that assumes there is a limit to the number of code points in a row that just one \X can match is wrong.

24. Code that assumes \X can never start with a \p{Mark} character is wrong.

25. Code that assumes that \X can never hold two non-\p{Mark} characters is wrong.

26. Code that assumes that it cannot use "\x{FFFF}" is wrong.

27. Code that assumes a non-BMP code point that requires two UTF-16 (surrogate) code units will encode to two separate UTF-8 characters, one per code unit, is wrong. It doesn’t: it encodes to single code point.

28. Code that transcodes from UTF-16 or UTF-32 with leading BOMs into UTF-8 is broken if it puts a BOM at the start of the resulting UTF-8. This is so stupid the engineer should have their eyelids removed.

29. Code that assumes the CESU-8 is a valid UTF encoding is wrong. Likewise, code that thinks encoding U+0000 as "\xC0\x80" is UTF-8 is broken and wrong. These guys also deserve the eyelid treatment.

30. Code that assumes characters like > always points to the right and < always points to the left are wrong — because they in fact do not.

31. Code that assumes if you first output character X and then character Y, that those will show up as XY is wrong. Sometimes they don’t.

32. Code that assumes that ASCII is good enough for writing English properly is stupid, shortsighted, illiterate, broken, evil, and wrong. Off with their heads! If that seems too extreme, we can compromise: henceforth they may type only with their big toe from one foot. (The rest will be duct taped.)

33. Code that assumes that all \p{Math} code points are visible characters is wrong.

34. Code that assumes \w contains only letters, digits, and underscores is wrong.

35. Code that assumes that ^ and ~ are punctuation marks is wrong.

36. Code that assumes that ü has an umlaut is wrong.

37. Code that believes things like ? contain any letters in them is wrong.

38. Code that believes \p{InLatin} is the same as \p{Latin} is heinously broken.

39. Code that believe that \p{InLatin} is almost ever useful is almost certainly wrong.

40. Code that believes that given $FIRST_LETTER as the first letter in some alphabet and $LAST_LETTER as the last letter in that same alphabet, that [${FIRST_LETTER}-${LAST_LETTER}] has any meaning whatsoever is almost always complete broken and wrong and meaningless.

41. Code that believes someone’s name can only contain certain characters is stupid, offensive, and wrong.

42. Code that tries to reduce Unicode to ASCII is not merely wrong, its perpetrator should never be allowed to work in programming again. Period. I’m not even positive they should even be allowed to see again, since it obviously hasn’t done them much good so far.

43. Code that believes there’s some way to pretend textfile encodings don’t exist is broken and dangerous. Might as well poke the other eye out, too.

44. Code that converts unknown characters to ? is broken, stupid, braindead, and runs contrary to the standard recommendation, which says NOT TO DO THAT! RTFM for why not.

45. Code that believes it can reliably guess the encoding of an unmarked textfile is guilty of a fatal mélange of hubris and naïveté that only a lightning bolt from Zeus will fix.

46. Code that believes you can use printf widths to pad and justify Unicode data is broken and wrong.

47. Code that believes once you successfully create a file by a given name, that when you run ls or readdir on its enclosing directory, you’ll actually find that file with the name you created it under is buggy, broken, and wrong. Stop being surprised by this!

48. Code that believes UTF-16 is a fixed-width encoding is stupid, broken, and wrong. Revoke their programming licence.

49. Code that treats code points from one plane one whit differently than those from any other plane is ipso facto broken and wrong. Go back to school.

50. Code that believes that stuff like /s/i can only match "S" or "s" is broken and wrong. You’d be surprised.

51. Code that uses \PM\pM* to find grapheme clusters instead of using \X is broken and wrong.

52. People who want to go back to the ASCII world should be whole-heartedly encouraged to do so, and in honor of their glorious upgrade they should be provided gratis with a pre-electric manual typewriter for all their data-entry needs. Messages sent to them should be sent via an ??????s telegraph at 40 characters per line and hand-delivered by a courier. STOP.

I don’t know how much more “default Unicode in ” you can get than what I’ve written. Well, yes I do: you should be using Unicode::Collate and Unicode::LineBreak, too. And probably more.

As you see, there are far too many Unicode things that you really do have to worry about for there to ever exist any such thing as “default to Unicode”.

What you’re going to discover, just as we did back in 5.8, that it is simply impossible to impose all these things on code that hasn’t been designed right from the beginning to account for them. Your well-meaning selfishness just broke the entire world.

And even once you do, there are still critical issues that require a great deal of thought to get right. There is no switch you can flip. Nothing but brain, and I mean real brain, will suffice here. There’s a heck of a lot of stuff you have to learn. Modulo the retreat to the manual typewriter, you simply cannot hope to sneak by in ignorance. This is the 21?? century, and you cannot wish Unicode away by willful ignorance.

You have to learn it. Period. It will never be so easy that “everything just works,” because that will guarantee that a lot of things don’t work — which invalidates the assumption that there can ever be a way to “make it all work.”

You may be able to get a few reasonable defaults for a very few and very limited operations, but not without thinking about things a whole lot more than I think you have.

As just one example, canonical ordering is going to cause some real headaches. "\x{F5}" ‘õ’, "o\x{303}" ‘õ’, "o\x{303}\x{304}" ‘?’, and "o\x{304}\x{303}" ‘o~’ should all match ‘õ’, but how in the world are you going to do that? This is harder than it looks, but it’s something you need to account for.

If there’s one thing I know about Perl, it is what its Unicode bits do and do not do, and this thing I promise you: “ _?_?_?_?_?_ _?_s_ _?_?_ _U_?_?_?_?_?_?_ _?_?_?_?_?_ _?_?_?_?_?_?_ _ ”

You cannot just change some defaults and get smooth sailing. It’s true that I run with PERL_UNICODE set to "SA", but that’s all, and even that is mostly for command-line stuff. For real work, I go through all the many steps outlined above, and I do it very, ** very** carefully.

¡?dl?? ???? ?do? pu? ???p ???u ? ???? ???nl poo?

You can do this without workarounds too. Just click and hold for a bit in the input field till the paste notification appears and then click on paste. That's it!

if you really wanted to do that you could then do

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

Wherever in the document you want the message.

You could also use the render file:

render file: "#{Rails.root}/public/404.html", layout: false, status: 404

Where you can choose to use the layout or not.

Another option is to use the Exceptions to control it:

raise ActiveRecord::RecordNotFound, "Record not found."

I got it worked with this command curl -F 'filename=@/home/yourhomedirextory/file.txt' http://yourserver/upload

I had a similar problem, but I only needed the bytes from the file. I read through links provided in the various answers, and ultimately tried writing one similar to #5 in Evgeniy's answer. They weren't kidding, it took a lot of code.

The basic premise is that each line of text is of unknown length. I will start with a SeekableByteChannel, read data into a ByteBuffer, then loop over it looking for EOL. When something is a "carryover" between loops, it increments a counter and then ultimately moves the SeekableByteChannel position around and reads the entire buffer.

It is verbose ... but it works. It was plenty fast for what I needed, but I'm sure there are more improvements that can be made.

The process method is stripped down to the basics for kicking off reading the file.

private long startOffset;
private long endOffset;
private SeekableByteChannel sbc;

private final ByteBuffer buffer = ByteBuffer.allocateDirect(1024);

public void process() throws IOException
{
    startOffset = 0;
    sbc = Files.newByteChannel(FILE, EnumSet.of(READ));
    byte[] message = null;
    while((message = readRecord()) != null)
    {
        // do something
    }
}

public byte[] readRecord() throws IOException
{
    endOffset = startOffset;

    boolean eol = false;
    boolean carryOver = false;
    byte[] record = null;

    while(!eol)
    {
        byte data;
        buffer.clear();
        final int bytesRead = sbc.read(buffer);

        if(bytesRead == -1)
        {
            return null;
        }

        buffer.flip();

        for(int i = 0; i < bytesRead && !eol; i++)
        {
            data = buffer.get();
            if(data == '\r' || data == '\n')
            {
                eol = true;
                endOffset += i;

                if(carryOver)
                {
                    final int messageSize = (int)(endOffset - startOffset);
                    sbc.position(startOffset);

                    final ByteBuffer tempBuffer = ByteBuffer.allocateDirect(messageSize);
                    sbc.read(tempBuffer);
                    tempBuffer.flip();

                    record = new byte[messageSize];
                    tempBuffer.get(record);
                }
                else
                {
                    record = new byte[i];

                    // Need to move the buffer position back since the get moved it forward
                    buffer.position(0);
                    buffer.get(record, 0, i);
                }

                // Skip past the newline characters
                if(isWindowsOS())
                {
                    startOffset = (endOffset + 2);
                }
                else
                {
                    startOffset = (endOffset + 1);
                }

                // Move the file position back
                sbc.position(startOffset);
            }
        }

        if(!eol && sbc.position() == sbc.size())
        {
            // We have hit the end of the file, just take all the bytes
            record = new byte[bytesRead];
            eol = true;
            buffer.position(0);
            buffer.get(record, 0, bytesRead);
        }
        else if(!eol)
        {
            // The EOL marker wasn't found, continue the loop
            carryOver = true;
            endOffset += bytesRead;
        }
    }

    // System.out.println(new String(record));
    return record;
}

It looks like Microsoft has deprecated lots of calls which use buffers to improve code security. However, the solutions they're providing aren't portable. Anyway, if you aren't interested in using the secure version of their calls (like fopen_s), you need to place a definition of _CRT_SECURE_NO_DEPRECATE before your included header files. For example:

#define _CRT_SECURE_NO_DEPRECATE
#include <stdio.h>

The preprocessor directive can also be added to your project settings to effect it on all the files under the project. To do this add _CRT_SECURE_NO_DEPRECATE to Project Properties -> Configuration Properties -> C/C++ -> Preprocessor -> Preprocessor Definitions.

To make sure you have the application's path (and not just the current directory), use this:

http://msdn.microsoft.com/en-us/library/system.diagnostics.process.getcurrentprocess.aspx

Now you have a Process object that represents the process that is running.

Then use Process.MainModule.FileName:

http://msdn.microsoft.com/en-us/library/system.diagnostics.processmodule.filename.aspx

Finally, use Path.GetDirectoryName to get the folder containing the .exe:

http://msdn.microsoft.com/en-us/library/system.io.path.getdirectoryname.aspx

So this is what you want:

string folder = Path.GetDirectoryName(Process.GetCurrentProcess().MainModule.FileName) + @"\Archive\";
string filter = "*.zip";
string[] files = Directory.GetFiles(folder, filter);

(Notice that "\Archive\" from your question is now @"\Archive\": you need the @ so that the \ backslashes aren't interpreted as the start of an escape sequence)

Hope that helps!

"+" is correct. If you really need %20, then replace the Plusses yourself afterwards.

Warning: This answer is heavily disputed (+8 vs. -6), so take this with a grain of salt.

android:layout_gravity="center"

or

android:gravity="center"

both works for me.

It's also possible to specify the ForeignKey() attribute on the navigation property:

[ForeignKey("HomeTeamID")]
public virtual Team HomeTeam { get; set; }
[ForeignKey("GuestTeamID")]
public virtual Team GuestTeam { get; set; }

That way you don't need to add any code to the OnModelCreate method

The other way to set default checked on radio buttons, especially if you're using angularjs is setting the 'ng-checked' flag to "true" eg: <input id="d_man" value="M" ng-disabled="some Value" type="radio" ng-checked="true">Man

the checked="checked" did not work for me..

Is just this:

int strcmp(char *str1, char *str2){
    while( (*str1 == *str2) && (*str1 != 0) ){
        ++*str1;
        ++*str2;
    }
    return (*str1-*str2);
}

if you want more fast, you can add "register " before type, like this: register char

then, like this:

int strcmp(register char *str1, register char *str2){
    while( (*str1 == *str2) && (*str1 != 0) ){
        ++*str1;
        ++*str2;
    }
    return (*str1-*str2);
}

this way, if possible, the register of the ALU are used.

The second one is correct under the circumstances (well, the least wrong, anyway).

Edit: "least wrong", as in the original code shows no good reason to be using new or delete in the first place, so you should probably just use:

std::vector<Monster> monsters;

The result will be simpler code and cleaner separation of responsibilities.

if (Value1.StartsWith("abc")) { found = true; }

There are other options you can use these controls which have multiple upload options and these controls have also Ajax support

You might want to start by learning what Javascript and php are. Javascript is a client side script language running in the browser of the machine of the client connected to the webserver on which php runs. These languages can not communicate directly.

Depending on your goal you'll need to issue an AJAX get or post request to the server and return a json/xml/html/whatever response you need and inject the result back in the DOM structure of the site. I suggest Jquery, BackboneJS or any other JS framework for this. See the Jquery documentation for examples.

If you have to pass php data to JS on the same site you can echo the data as JS and turn your php data using json_encode() into JS.

<script type="text/javascript>
    var foo = <?php echo json_encode($somePhpVar); ?>
</script>

You could give the row an id, e.g.

<tr id="special"> ... </tr>

and then use jquery to say something like:

$('#special').onclick(function(){ window="http://urltolinkto.com/x/y/z";})

Another way:

using Unofficial (Full Size: 26.1 MB) VC++ All in one that contained your needed files:

http://www.wincert.net/forum/topic/9790-aio-microsoft-visual-bcfj-redistributable-x86x64/

OR (Smallest 5.10 MB) Microsoft Visual Basic/C++ Runtimes 1.1.1 RePacked Here:

http://www.wincert.net/forum/topic/9794-bonus-microsoft-visual-basicc-runtimes-111/

Using lamda, just multiple the result with -1 to get max priority queue.

PriorityQueue<> q = new PriorityQueue<Integer>(
                       (a,b) ->  -1 * Integer.compare(a, b)
                    );

Filters are mostly used in logger files it varies according to the logger you using in the project Lemme explain for log4j2:

<Filters>
                <!-- It prevents error -->
                <ThresholdFilter level="error" onMatch="DENY" onMismatch="NEUTRAL"/>
                <!-- It prevents debug -->
                <ThresholdFilter level="debug" onMatch="DENY" onMismatch="NEUTRAL" />
                <!-- It allows all levels except debug/trace -->
                <ThresholdFilter level="info" onMatch="ACCEPT" onMismatch="DENY" /> 
            </Filters>

Filters are used to restrict the data and i used threshold filter further to restrict the levels of data in the flow I mentioned the levels that can be restricted over there. For your further refrence see the level order of log4j2 - Log4J Levels: ALL > TRACE > DEBUG > INFO > WARN > ERROR > FATAL > OFF

Although this is an old document, but it helped me resolve the problem of 'HintPath' being ignored on another machine. It was because the referenced DLL needed to be in source control as well:

https://msdn.microsoft.com/en-us/library/ee817675.aspx#tdlg_ch4_includeoutersystemassemblieswithprojects

Excerpt:

To include and then reference an outer-system assembly
1. In Solution Explorer, right-click the project that needs to reference the assembly,,and then click Add Existing Item.
2. Browse to the assembly, and then click OK. The assembly is then copied into the project folder and automatically added to VSS (assuming the project is already under source control).
3. Use the Browse button in the Add Reference dialog box to set a file reference to assembly in the project folder.

Jdbc jobstore

If you are using jdbc jobstore Quartz uses a different classloader. That prevents all the workarounds for autowiring, since objects from spring will not be compatible at quartz side, because they originited from a different class loader.

To fix that, the default classloader has to be set in the quartz properties file like this:

org.quartz.scheduler.classLoadHelper.class=org.quartz.simpl.ThreadContextClassLoadHelper

As reference: https://github.com/quartz-scheduler/quartz/issues/221

Assuming that you already put your object as attribute on the session map of the current instance of the FacesContext from your managed-bean, you can get it from the JSF page by :

<h:outputText value="#{sessionScope['yourObject'] }" />

If your object has a property, get it by:

<h:ouputText value="#{sessionScope['yourObject'].anyProperty }" />

I've found that you can move div elements to the next line simply by setting the property Display: block;

On each div.

I set up finally using microweber/screen as proposed by @boksiora.
Initially when trying the mentioned link here what I got:

Please download this script from here https://github.com/microweber/screen

I'm on Linux. So if you want to run it, you may adjust my step follow to your environment.
Here are the step I did on my shell on DOCUMENT_ROOT folder:

$ sudo wget https://github.com/microweber/screen/archive/master.zip
$ sudo unzip master.zip
$ sudo mv screen-master screen
$ sudo chmod +x screen/bin/phantomjs
$ sudo yum install fontconfig
$ sudo yum install freetype*
$ cd screen
$ sudo curl -sS https://getcomposer.org/installer | php
$ sudo php composer.phar update
$ cd ..
$ sudo chown -R apache screen
$ sudo chgrp -R www screen
$ sudo service httpd restart

Point your browser to screen/demo/shot.php?url=google.com. When you see the screenshot, you are done. Discussion for more advance setting is available here and here.

Mostly in Hibernate , need to add the Entity class in hibernate.cfg.xml like-

<hibernate-configuration>
  <session-factory>

    ....
    <mapping class="xxx.xxx.yourEntityName"/>
 </session-factory>
</hibernate-configuration>

Or simply add one line of:

Text='<%# Eval("Comments").ToString().Replace("\n","<br />") %>'

I had to use:

-webkit-perspective: 1000;
-webkit-backface-visibility: hidden;    

on the element, or I would still get a flickr the first time a transition occurred after page load

This is what you can do to source an .env (and .flaskenv) file in the pycharm flask/django console. It would also work for a normal python console of course.

1. Do pip install python-dotenv in your environment (the same as being pointed to by pycharm).

2. Go to: Settings > Build ,Execution, Deployment > Console > Flask/django Console

3. In "starting script" include something like this near the top:

   from dotenv import load_dotenv load_dotenv(verbose=True)

The .env file can look like this: export KEY=VALUE

It doesn't matter if one includes export or not for dotenv to read it.

As an alternative you could also source the .env file in the activate shell script for the respective virtual environement.

Try

//re:*[. ='match']

I also had a task like this and when I was done, using the above method, a new method occured to me: Why don't you do this:

1. Reverse the string ("string one" becomes "eno gnirts").
2. Use the good old Find (which is hardcoded for left-to-right).
3. Reverse it into readable string again.

How does this sound?

Here is my step by step experience, inspired by typeahead examples, from a Scala/PlayFramework app we are working on.

In a script LearnerNameTypeAhead.coffee (convertible of course to JS) I have:

$ ->
  learners = new Bloodhound(
    datumTokenizer: Bloodhound.tokenizers.obj.whitespace("value")
    queryTokenizer: Bloodhound.tokenizers.whitespace
    remote: "/learner/namelike?nameLikeStr=%QUERY"
  )
  learners.initialize()
  $("#firstName").typeahead 
    minLength: 3
    hint: true
    highlight:true
   ,
    name: "learners"
    displayKey: "value"
    source: learners.ttAdapter()

I included the typeahead bundle and my script on the page, and there is a div around my input field as follows:

<script [email protected]("javascripts/typeahead.bundle.js")></script>
<script [email protected]("javascripts/LearnerNameTypeAhead.js") type="text/javascript" ></script>
<div>
  <input name="firstName" id="firstName" class="typeahead" placeholder="First Name" value="@firstName">
</div>

The result is that for each character typed in the input field after the first minLength (3) characters, the page issues a GET request with a URL looking like /learner/namelike?nameLikeStr= plus the currently typed characters. The server code returns a json array of objects containing fields "id" and "value", for example like this:

[ {
    "id": "109",
    "value": "Graham Jones"
  },
  {
    "id": "5833",
    "value": "Hezekiah Jones"
} ]

For play I need something in the routes file:

GET /learner/namelike controllers.Learners.namesLike(nameLikeStr:String)

And finally, I set some of the styling for the dropdown, etc. in a new typeahead.css file which I included in the page's <head> (or accessible .css)

.tt-dropdown-menu {
  width: 252px;
  margin-top: 12px;
  padding: 8px 0;
  background-color: #fff;
  border: 1px solid #ccc;
  border: 1px solid rgba(0, 0, 0, 0.2);
  -webkit-border-radius: 8px;
     -moz-border-radius: 8px;
          border-radius: 8px;
  -webkit-box-shadow: 0 5px 10px rgba(0,0,0,.2);
     -moz-box-shadow: 0 5px 10px rgba(0,0,0,.2);
          box-shadow: 0 5px 10px rgba(0,0,0,.2);
}
.typeahead {
  background-color: #fff;
}
.typeahead:focus {
  border: 2px solid #0097cf;
}
.tt-query {
  -webkit-box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
     -moz-box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
          box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
}
.tt-hint {
  color: #999
}
.tt-suggestion {
  padding: 3px 20px;
  font-size: 18px;
  line-height: 24px;
}
.tt-suggestion.tt-cursor {
  color: #fff;
  background-color: #0097cf;
}
.tt-suggestion p {
  margin: 0;
}

You should set async = false in head. Use post/get instead of ajax.

jQuery.ajaxSetup({ async: false });

    $.post({
        url: 'api.php',
        data: 'id1=' + q + '',
        dataType: 'json',
        success: function (data) {

            id = data[0];
            vname = data[1];

        }
    });

In Addition to the above answers, there probably should be noted that there is a legacy way to implement the initialization. There is an interface called Initializable from the fxml library.

import javafx.fxml.Initializable;

class MyController implements Initializable {
    @FXML private TableView<MyModel> tableView;

    @Override
    public void initialize(URL location, ResourceBundle resources) {
        tableView.getItems().addAll(getDataFromSource());
    }
}

Parameters:

location - The location used to resolve relative paths for the root object, or null if the location is not known.
resources - The resources used to localize the root object, or null if the root object was not localized. 

And the note of the docs why the simple way of using @FXML public void initialize() works:

NOTE This interface has been superseded by automatic injection of location and resources properties into the controller. FXMLLoader will now automatically call any suitably annotated no-arg initialize() method defined by the controller. It is recommended that the injection approach be used whenever possible.

SELECT
  category,
  COUNT(*) AS `num`
FROM
  posts
GROUP BY
  category

All these suggestions work unless you put the anchors inside an UL list.

<ul>
    <li>
        <a>click me</a>>
    </li>
</ul>

Then any cascade style sheet rules are overridden in the Chrome browser. The width becomes auto. Then you must use inline CSS rules directly on the anchor itself.

Inspired by the accepted answer by @ford04 I had even better approach dealing with it, instead of using useEffect inside useAsync create a new function that returns a callback for componentWillUnmount :

function asyncRequest(asyncRequest, onSuccess, onError, onComplete) {
  let isMounted=true
  asyncRequest().then((data => isMounted ? onSuccess(data):null)).catch(onError).finally(onComplete)
  return () => {isMounted=false}
}

...

useEffect(()=>{
        return asyncRequest(()=>someAsyncTask(arg), response=> {
            setSomeState(response)
        },onError, onComplete)
    },[])

I think , your app installed by other account.( multiple account mode feature ) You can uninstall app in Setting>Apps>"app name"> Uninstall

Below is an extension method that will allow you to write code like this:

int id = request.QueryString.GetValue<int>("id");
DateTime date = request.QueryString.GetValue<DateTime>("date");

It makes use of TypeDescriptor to perform the conversion. Based on your needs, you could add an overload which takes a default value instead of throwing an exception:

public static T GetValue<T>(this NameValueCollection collection, string key)
{
    if(collection == null)
    {
        throw new ArgumentNullException("collection");
    }

    var value = collection[key];

    if(value == null)
    {
        throw new ArgumentOutOfRangeException("key");
    }

    var converter = TypeDescriptor.GetConverter(typeof(T));

    if(!converter.CanConvertFrom(typeof(string)))
    {
        throw new ArgumentException(String.Format("Cannot convert '{0}' to {1}", value, typeof(T)));
    }

    return (T) converter.ConvertFrom(value);
}

Yeah I agree with your approach. To merge mobiledevicesupport into master you can use

git checkout master
git pull origin master //Get all latest commits of master branch
git merge mobiledevicesupport

Similarly you can also merge master in mobiledevicesupport.

Q. If cross merging is an issue or not.

A. Well it depends upon the commits made in mobile* branch and master branch from the last time they were synced. Take this example: After last sync, following commits happen to these branches

Master branch: A -> B -> C [where A,B,C are commits]
Mobile branch: D -> E

Now, suppose commit B made some changes to file a.txt and commit D also made some changes to a.txt. Let us have a look at the impact of each operation of merging now,

git checkout master //Switches to master branch
git pull // Get the commits you don't have. May be your fellow workers have made them.
git merge mobiledevicesupport // It will try to add D and E in master branch.

Now, there are two types of merging possible

1. Fast forward merge
2. True merge (Requires manual effort)

Git will first try to make FF merge and if it finds any conflicts are not resolvable by git. It fails the merge and asks you to merge. In this case, a new commit will occur which is responsible for resolving conflicts in a.txt.

So Bottom line is Cross merging is not an issue and ultimately you have to do it and that is what syncing means. Make sure you dirty your hands in merging branches before doing anything in production.

We can use query instead of queryForObject, major difference between query and queryForObject is that query return list of Object(based on Row mapper return type) and that list can be empty if no data is received from database while queryForObject always expect only single object be fetched from db neither null nor multiple rows and in case if result is empty then queryForObject throws EmptyResultDataAccessException, I had written one code using query that will overcome the problem of EmptyResultDataAccessException in case of null result.

----------


public UserInfo getUserInfo(String username, String password) {
      String sql = "SELECT firstname, lastname,address,city FROM users WHERE id=? and pass=?";
      List<UserInfo> userInfoList = jdbcTemplate.query(sql, new Object[] { username, password },
              new RowMapper<UserInfo>() {
                  public UserInfo mapRow(ResultSet rs, int rowNum) throws SQLException {
                      UserInfo user = new UserInfo();
                      user.setFirstName(rs.getString("firstname"));
                      user.setLastName(rs.getString("lastname"));
                      user.setAddress(rs.getString("address"));
                      user.setCity(rs.getString("city"));

                      return user;
                  }
              });

      if (userInfoList.isEmpty()) {
          return null;
      } else {
          return userInfoList.get(0);
      }
  }

What you want appear to want is the following, but this is NOT RECOMMENDED:

>>> for line in open('dangerous.txt'):
...     exec('%s = %s' % tuple(line.split(':', 1)))
... 
>>> var_a
'home'

This creates somewhat similar behavior to PHP's register_globals and hence has the same security issues. Additionally, the use of exec that I showed allows arbitrary code execution. Only use this if you are absolutely sure that the contents of the text file can be trusted under all circumstances.

You should really consider binding the variables not to the local scope, but to an object, and use a library that parses the file contents such that no code is executed. So: go with any of the other solutions provided here.

(Please note: I added this answer not as a solution, but as an explicit non-solution.)

Another programmatic Kotlin Alternative:

mButton.transformationMethod = null

With Visual Studio 2015 I have activated it with the following steps.

1. Programs and Features --> Select Visual Studio > Change
2. Choose Modify
3. Windows and Webdevelopment --> Tick "Microsoft Office Developer Tools"
4. Start Update

It should work now.

If you used Aptitude (apt-get) to install Jenkins on Ubuntu 12.04, uncomment the JAVA_ARGS line in the top few lines of /etc/default/jenkins:

# arguments to pass to java
#JAVA_ARGS="-Xmx256m"   # <--default value
JAVA_ARGS="-Xmx2048m"
#JAVA_ARGS="-Djava.net.preferIPv4Stack=true" # make jenkins listen on IPv4 address

Tested this on a CentOS VMWare image that I keep around for this sort of thing. Note that you probably want to avoid putting passwords as command-line arguments, because anybody on the entire machine can read them out of 'ps -ef'.

That said, this will work:

user="$1"
password="$2"
adduser $user
echo $password | passwd --stdin $user

We've seen in our projects that a post request with JSON and files is creating a lot of confusion between the frontend and backend developers, leading to unnecessary wastage of time.

Here's a better approach: convert file bytes array to Base64 string and send it in the JSON.

public Class UserDTO {
    private String firstName;
    private String lastName;
    private FileDTO profilePic; 
}

public class FileDTO {
    private String base64;
    // just base64 string is enough. If you want, send additional details
    private String name;
    private String type;
    private String lastModified;
}

@PostMapping("/user")
public String saveUser(@RequestBody UserDTO user) {
    byte[] fileBytes = Base64Utils.decodeFromString(user.getProfilePic().getBase64());
    ....
}

JS code to convert file to base64 string:

var reader = new FileReader();
reader.readAsDataURL(file);
reader.onload = function () {

  const userDTO = {
    firstName: "John",
    lastName: "Wick",
    profilePic: {
      base64: reader.result,
      name: file.name,
      lastModified: file.lastModified,
      type: file.type
    }
  }
  
  // post userDTO
};
reader.onerror = function (error) {
  console.log('Error: ', error);
};

Because that gtab82 table isn't in your FROM or JOIN clause. You refer gtab82 table in these cases: gtab82.memno and gtab82.memacid

First, you should use any WebSocket or polling mechanics to notify the frontend part about changes that happened. I use Flask-SocketIO wrapper, and very happy with async messaging for my tiny apps.

Nest, you can do all logic which you need in a separate thread(s), and notify the frontend via SocketIO object (Flask holds continuous open connection with every frontend client).

As an example, I just implemented page reload on backend file modifications:

<!doctype html>
<script>
    sio = io()

    sio.on('reload',(info)=>{
        console.log(['sio','reload',info])
        document.location.reload()
    })
</script>

class App(Web, Module):

    def __init__(self, V):
        ## flask module instance
        self.flask = flask
        ## wrapped application instance
        self.app = flask.Flask(self.value)
        self.app.config['SECRET_KEY'] = config.SECRET_KEY
        ## `flask-socketio`
        self.sio = SocketIO(self.app)
        self.watchfiles()

    ## inotify reload files after change via `sio(reload)``
    def watchfiles(self):
        from watchdog.observers import Observer
        from watchdog.events import FileSystemEventHandler
        class Handler(FileSystemEventHandler):
            def __init__(self,sio):
                super().__init__()
                self.sio = sio
            def on_modified(self, event):
                print([self.on_modified,self,event])
                self.sio.emit('reload',[event.src_path,event.event_type,event.is_directory])
        self.observer = Observer()
        self.observer.schedule(Handler(self.sio),path='static',recursive=True)
        self.observer.schedule(Handler(self.sio),path='templates',recursive=True)
        self.observer.start()

make sure your controller extends Symfony\Bundle\FrameworkBundle\Controller\Controller;

you should also check app/console debug:router in terminal to see what name symfony has named the route

in my case it used a minus instead of an underscore

i.e blog-show

$uri = $this->generateUrl('blog-show', ['slug' => 'my-blog-post']);

just combine the value and the stud_name e.g. 1_sre and split the value when get it into php. Javascript seems like hammer to crack a nut. N.B. this method assumes you can edit the the html. Here is what the html might look like:

<form name='add'>
Age: <select name='age'>
     <option value='1_sre'>23</option>
     <option value='2_sam>24</option>
     <option value='5_john>25</option>
     </select>
<input type='submit' name='submit'/>
</form>

This might be just a requirement of PyMySql in Python, but I found that I had to name the exact table that I wanted the ID for:

In:

cnx = pymysql.connect(host='host',
                            database='db',
                            user='user',
                            password='pass')
cursor = cnx.cursor()
update_batch = """insert into batch set type = "%s" , records = %i, started = NOW(); """
second_query = (update_batch % ( "Batch 1", 22  ))
cursor.execute(second_query)
cnx.commit()
batch_id = cursor.execute('select last_insert_id() from batch')
cursor.close()

batch_id

Out: 5
... or whatever the correct Batch_ID value actually is

Simplest solution:

$date = new DateTime('+1 day');
echo $date->format('Y-m-d H:i:s');

The existing answers (pass the data in the Intent passed to startActivity()) show the normal way to solve this problem. There is another solution that can be used in the odd case where you're creating an Activity that will be started by another app (for example, one of the edit activities in a Tasker plugin) and therefore do not control the Intent which launches the Activity.

You can create a base-class Activity that has a constructor with a parameter, then a derived class that has a default constructor which calls the base-class constructor with a value, as so:

class BaseActivity extends Activity
{
    public BaseActivity(String param)
    {
        // Do something with param
    }
}

class DerivedActivity extends BaseActivity
{
    public DerivedActivity()
    {
        super("parameter");
    }
}

If you need to generate the parameter to pass to the base-class constructor, simply replace the hard-coded value with a function call that returns the correct value to pass.

while(@$i++<count($a))
echo $a[$i-1];

1. Use PHP's inbuilt ctype_alnum

You dont need to use a regex for this, PHP has an inbuilt function ctype_alnum which will do this for you, and execute faster:

<?php
$strings = array('AbCd1zyZ9', 'foo!#$bar');
foreach ($strings as $testcase) {
    if (ctype_alnum($testcase)) {
        echo "The string $testcase consists of all letters or digits.\n";
    } else {
        echo "The string $testcase does not consist of all letters or digits.\n";
    }
}
?>

2. Alternatively, use a regex

If you desperately want to use a regex, you have a few options.

Firstly:

preg_match('/^[\w]+$/', $string);

\w includes more than alphanumeric (it includes underscore), but includes all of \d.

Alternatively:

/^[a-zA-Z\d]+$/

Or even just:

/^[^\W_]+$/

The problem for me was that I had .rnd in my home directory but it was owned by root. Deleting it and reissuing the openssl command fixed this.

I liked PostMan, it was the main reason why I kept using Chrome, now I'm good with HttpRequester

https://addons.mozilla.org/En-us/firefox/addon/httprequester/?src=search

var settings = 
    JSON.parse(
        require('fs').readFileSync(
            require('path').resolve(
                __dirname, 
                'settings.json'),
            'utf8'));

select tab1.name,
count(distinct tab2.id) as tab2_record_count
count(distinct tab3.id) as tab3_record_count
count(distinct tab4.id) as tab4_record_count
from tab1
left join tab2 on tab2.tab1_id = tab1.id
left join tab3 on tab3.tab1_id = tab1.id
left join tab4 on tab4.tab1_id = tab1.id

You can try to override onCreateAnimation, parameter and catch enter==false. This will fire before every back press.

@Override
public Animation onCreateAnimation(int transit, boolean enter, int nextAnim) {            
        if(!enter){
            //leaving fragment
            Log.d(TAG,"leaving fragment");
        }
        return super.onCreateAnimation(transit, enter, nextAnim);
    }

Like pagination you can use below formule for taking slice of list or elements:

var slice = myList.Skip((pageNumber - 1) * pageSize)
                  .Take(pageSize);

Example 1: first five items

var pageNumber = 1;
var pageSize = 5;

Example 2: second five items

var pageNumber = 2;
var pageSize = 5;

Example 3: third five items

var pageNumber = 3;
var pageSize = 5;

If notice to formule parameters pageSize = 5 and pageNumber is changing, if you want to change number of items in slicing you change pageSize.

There is better way. I'm using it in pages where I'm using kendo angularJS directives and grids has'nt IDs...

change: function (e) {
   var selectedDataItem = e != null ? e.sender.dataItem(e.sender.select()) : null;
}

With Cinchoo ETL - an open source library, you can export DataTable to JSON easily with few lines of code

StringBuilder sb = new StringBuilder();
string connectionstring = @"Data Source=(localdb)\MSSQLLocalDB;Initial Catalog=Northwind;Integrated Security=True";
using (var conn = new SqlConnection(connectionstring))
{
    conn.Open();
    var comm = new SqlCommand("SELECT * FROM Customers", conn);
    SqlDataAdapter adap = new SqlDataAdapter(comm);

    DataTable dt = new DataTable("Customer");
    adap.Fill(dt);

    using (var parser = new ChoJSONWriter(sb))
        parser.Write(dt);
}

Console.WriteLine(sb.ToString());

Output:

{
  "Customer": [
    {
      "CustomerID": "ALFKI",
      "CompanyName": "Alfreds Futterkiste",
      "ContactName": "Maria Anders",
      "ContactTitle": "Sales Representative",
      "Address": "Obere Str. 57",
      "City": "Berlin",
      "Region": null,
      "PostalCode": "12209",
      "Country": "Germany",
      "Phone": "030-0074321",
      "Fax": "030-0076545"
    },
    {
      "CustomerID": "ANATR",
      "CompanyName": "Ana Trujillo Emparedados y helados",
      "ContactName": "Ana Trujillo",
      "ContactTitle": "Owner",
      "Address": "Avda. de la Constitución 2222",
      "City": "México D.F.",
      "Region": null,
      "PostalCode": "05021",
      "Country": "Mexico",
      "Phone": "(5) 555-4729",
      "Fax": "(5) 555-3745"
    }
  ]
}

Its simple

$(function() {
        $("#datePicker").datetimepicker({
            defaultDate:'now'

        });
    });

This will set today as default

Only static functions are called with class name.

classname::Staicfunction();

Non static functions have to be called using objects.

classname obj;
obj.Somefunction();

This is exactly what your error means. Since your function is non static you have to use a object reference to invoke it.

I got trouble to get it so I post pictures showing different options:

Chrome 75.0.3770.142 [29 July 2018]

Very very similar UI since at least Chrome 38.0.2125.111 [11 December 2014]

In tab Sources :

When button is activated, you can Pause On Caught Exceptions with the checkbox below:

Previous versions

This can reasonably be achieved in a single line statement in API 12 and above. Below is an example where v is the view you wish to animate;

v.animate().translationXBy(-1000).start();

This will slide the View in question off to the left by 1000px. To slide the view back onto the UI we can simply do the following.

v.animate().translationXBy(1000).start();

I hope someone finds this useful.

Put them in public folder and call it in the view with something like href="{{ asset('public/css/style.css') }}". Note that the public should be included when you call the assets.

It is possible to build an arbitrary GET or POST request and send it to any server accessible to a victims browser. This includes devices on your local network, such as Printers and Routers.

There are many ways of building a CSRF exploit. A simple POST based CSRF attack can be sent using .submit() method. More complex attacks, such as cross-site file upload CSRF attacks will exploit CORS use of the xhr.withCredentals behavior.

CSRF does not violate the Same-Origin Policy For JavaScript because the SOP is concerned with JavaScript reading the server's response to a clients request. CSRF attacks don't care about the response, they care about a side-effect, or state change produced by the request, such as adding an administrative user or executing arbitrary code on the server.

Make sure your requests are protected using one of the methods described in the OWASP CSRF Prevention Cheat Sheet. For more information about CSRF consult the OWASP page on CSRF.

Your best bet would be to anticipate prefixes, so:

"(|(displayName=SEARCHKEY*)(displayName=ITSM - SEARCHKEY*)(displayName=alt prefix - SEARCHKEY*))"

Clunky, but I'm doing a similar thing within my organization.

or //div[@id='id-74385'][@class='guest clearfix']

lsof and fuser are indeed two ways to find the process that keeps a certain file open. If you just want umount to succeed, you should investigate its -f and -l options.

AFAIK $(window).height(); returns the height of your window and $(document).height(); returns the height of your document

string ConnectionString = ConfigurationManager.ConnectionStrings["DBCS"].ConnectionString;
using (SqlConnection con = new SqlConnection(ConnectionString))
{
//Create the SqlCommand object
SqlCommand cmd = new SqlCommand(“spAddEmployee”, con);

//Specify that the SqlCommand is a stored procedure
cmd.CommandType = System.Data.CommandType.StoredProcedure;

//Add the input parameters to the command object
cmd.Parameters.AddWithValue(“@Name”, txtEmployeeName.Text);
cmd.Parameters.AddWithValue(“@Gender”, ddlGender.SelectedValue);
cmd.Parameters.AddWithValue(“@Salary”, txtSalary.Text);

//Add the output parameter to the command object
SqlParameter outPutParameter = new SqlParameter();
outPutParameter.ParameterName = “@EmployeeId”;
outPutParameter.SqlDbType = System.Data.SqlDbType.Int;
outPutParameter.Direction = System.Data.ParameterDirection.Output;
cmd.Parameters.Add(outPutParameter);

//Open the connection and execute the query
con.Open();
cmd.ExecuteNonQuery();

//Retrieve the value of the output parameter
string EmployeeId = outPutParameter.Value.ToString();
}

For ASP.NET5, i.e. ASPNETCORE, you can do the following in configure:

app.UseRequestLocalization(new RequestLocalizationOptions
{
    DefaultRequestCulture = new RequestCulture(new CultureInfo("en-gb")),
    SupportedCultures = new List<CultureInfo>
    {
        new CultureInfo("en-gb")
    },
            SupportedUICultures = new List<CultureInfo>
    {
        new CultureInfo("en-gb")
    }
});

Here's a series of blog posts that gives more information.

This may be because of changing lower_case_table_names after a server has been already initialized.

From the docs:

lower_case_table_names can only be configured when initializing the server. Changing the lower_case_table_names setting after the server is initialized is prohibited.

The solution to this problem is to set lower_case_table_names parameter at server installation as described in the following answer:

Can't set lower_case_table_names in MySQL 8.x on Windows 10

1. Picasso is an easy to use image loader, same goes for Imageloader. Fresco uses a different approach to image loading, i haven't used it yet but it looks too me more like a solution for getting image from network and caching them then showing the images. then the other way around like Picasso/Imageloader/Glide which to me are more Showing image on screen that also does getting images from network and caching them.

2. Glide tries to be somewhat interchangeable with Picasso.I think when they were created Picasso's mind set was follow HTTP spec's and let the server decide the caching policies and cache full sized and resize on demand. Glide is the same with following the HTTP spec but tries to have a smaller memory footprint by making some different assumptions like cache the resized images instead of the fullsized images, and show images with RGB_565 instead of RGB_8888. Both libraries offer full customization of the default settings.

3. As to which library is the best to use is really hard to say. Picasso, Glide and Imageloader are well respected and well tested libraries which all are easy to use with the default settings. Both Picasso and Glide require only 1 line of code to load an image and have a placeholder and error image. Customizing the behaviour also doesn't require that much work. Same goes for Imageloader which is also an older library then Picasso and Glide, however I haven't used it so can't say much about performance/memory usage/customizations but looking at the readme on github gives me the impression that it is also relatively easy to use and setup. So in choosing any of these 3 libraries you can't make the wrong decision, its more a matter of personal taste. For fresco my opinion is that its another facebook library so we have to see how that is going to work out for them, so far there track record isn't that good. Like the facebook SDK is still isn't officially released on mavenCentral I have not used to facebook sdk since sept 2014 and it seems they have put the first version online on mavenCentral in oct 2014. So it will take some time before we can get any good opinion about it.

4. between the 3 big name libraries I think there are no significant differences. The only one that stand out is fresco but that is because it has a different approach and is new and not battle tested.

I think that using colnames and rownames makes the most sense; here's why.

Using names has several disadvantages. You have to remember that it means "column names", and it only works with data frame, so you'll need to call colnames whenever you use matrices. By calling colnames, you only have to remember one function. Finally, if you look at the code for colnames, you will see that it calls names in the case of a data frame anyway, so the output is identical.

rownames and row.names return the same values for data frame and matrices; the only difference that I have spotted is that where there aren't any names, rownames will print "NULL" (as does colnames), but row.names returns it invisibly. Since there isn't much to choose between the two functions, rownames wins on the grounds of aesthetics, since it pairs more prettily withcolnames. (Also, for the lazy programmer, you save a character of typing.)

This boils down to a difference between definitions and declarations.

• You can declare functions and variables multiple times, in different translation units, or in the same translation unit. Once you declare a function or a variable, you can use it from that point on.
• You can define a non-static function or a variable only once in all of your translation units. Defining non-static items more than once causes linker errors.

Headers generally contain declarations; cpp files contain definitions. When you include a file with definitions more than once, you get duplicates during linking.

In your situation one defintion comes from foo.cpp, and the other definition comes from main.cpp, which includes foo.cpp.

Note: if you change foo to be static, you would have no linking errors. Despite the lack of errors, this is not a good thing to do.
