Python3:

One solution:

enumm = {0: 1, 1: 2, 2: 3, 4: 4, 5: 5, 6: 6, 7: 7}
for i, k in enumerate(enumm):
    print("{}) d.key={}, d.value={}".format(i, k, enumm[k]))

Output:
0) enumm.key=0, enumm.value=1
1) enumm.key=1, enumm.value=2
2) enumm.key=2, enumm.value=3
3) enumm.key=4, enumm.value=4
4) enumm.key=5, enumm.value=5
5) enumm.key=6, enumm.value=6
6) enumm.key=7, enumm.value=7

An another example:

d = {1 : {'a': 1, 'b' : 2, 'c' : 3},
     2 : {'a': 10, 'b' : 20, 'c' : 30}
    }    
for i, k in enumerate(d):
        print("{}) key={}, value={}".format(i, k, d[k])

Output:    
    0) key=1, value={'a': 1, 'b': 2, 'c': 3}
    1) key=2, value={'a': 10, 'b': 20, 'c': 30}

As other users have mentioned, enumerate is a generator that adds an incremental index next to each item of an iterable.

So if you have a list say l = ["test_1", "test_2", "test_3"], the list(enumerate(l)) will give you something like this: [(0, 'test_1'), (1, 'test_2'), (2, 'test_3')].

Now, when this is useful? A possible use case is when you want to iterate over items, and you want to skip a specific item that you only know its index in the list but not its value (because its value is not known at the time).

for index, value in enumerate(joint_values):
   if index == 3:
       continue

   # Do something with the other `value`

So your code reads better because you could also do a regular for loop with range but then to access the items you need to index them (i.e., joint_values[i]).

Although another user mentioned an implementation of enumerate using zip, I think a more pure (but slightly more complex) way without using itertools is the following:

def enumerate(l, start=0):
    return zip(range(start, len(l) + start), l)

Example:

l = ["test_1", "test_2", "test_3"]
enumerate(l)
enumerate(l, 10)

Output:

[(0, 'test_1'), (1, 'test_2'), (2, 'test_3')]

[(10, 'test_1'), (11, 'test_2'), (12, 'test_3')]

As mentioned in the comments, this approach with range will not work with arbitrary iterables as the original enumerate function does.

As with @Kametrixom answer here I believe returning an array would be better than returning AnySequence, since you can have access to all of Array's goodies such as count, etc.

Here's the re-write:

public protocol EnumCollection : Hashable {}
extension EnumCollection {
    public static func allValues() -> [Self] {
        typealias S = Self
        let retVal = AnySequence { () -> AnyGenerator<S> in
            var raw = 0
            return AnyGenerator {
                let current : Self = withUnsafePointer(&raw) { UnsafePointer($0).memory }
                guard current.hashValue == raw else { return nil }
                raw += 1
                return current
            }
        }

        return [S](retVal)
    }
}

from @Adam Rosenfield's answer, the formatting string of fscanf would be changed like below:

"%4095[^\r\n]%n%*[\n\r]"

it will work in osx, linux, windows line endings.

In addition to tcash21's numeric indexing if OP may have been looking for negative indexing by name. Here's a few ways I know, some are risky than others to use:

mtcars[, -which(names(mtcars) == "carb")]  #only works on a single column
mtcars[, names(mtcars) != "carb"]          #only works on a single column
mtcars[, !names(mtcars) %in% c("carb", "mpg")] 
mtcars[, -match(c("carb", "mpg"), names(mtcars))] 
mtcars2 <- mtcars; mtcars2$hp <- NULL         #lost column (risky)


library(gdata) 
remove.vars(mtcars2, names=c("mpg", "carb"), info=TRUE) 

Generally I use:

mtcars[, !names(mtcars) %in% c("carb", "mpg")] 

because I feel it's safe and efficient.

Try this:

/* Variable Declaration */
DECLARE @EmpID AS SMALLINT
DECLARE @SQLQuery AS NVARCHAR(500)
DECLARE @ParameterDefinition AS NVARCHAR(100)
DECLARE @TableName AS NVARCHAR(100)
/* set the parameter value */
SET @EmpID = 1001
SET @TableName = 'tblEmployees'
/* Build Transact-SQL String by including the parameter */
SET @SQLQuery = 'SELECT * FROM ' + @TableName + ' WHERE EmployeeID = @EmpID' 
/* Specify Parameter Format */
SET @ParameterDefinition =  '@EmpID SMALLINT'
/* Execute Transact-SQL String */
EXECUTE sp_executesql @SQLQuery, @ParameterDefinition, @EmpID

in python 3.6 and newer, you can format it just like this:

new_string = f'{s} {i}'
print(new_string)

or just:

print(f'{s} {i}')

I've done this before. I had a pdf that I generated with fpdf, and I needed to add on a variable amount of PDFs to it.

So I already had an fpdf object and page set up (http://www.fpdf.org/) And I used fpdi to import the files (http://www.setasign.de/products/pdf-php-solutions/fpdi/) FDPI is added by extending the PDF class:

class PDF extends FPDI
{

} 



    $pdffile = "Filename.pdf";
    $pagecount = $pdf->setSourceFile($pdffile);  
    for($i=0; $i<$pagecount; $i++){
        $pdf->AddPage();  
        $tplidx = $pdf->importPage($i+1, '/MediaBox');
        $pdf->useTemplate($tplidx, 10, 10, 200); 
    }

This basically makes each pdf into an image to put into your other pdf. It worked amazingly well for what I needed it for.

On Linux, you can use ldconfig, which maintains the ld.so configuration and cache, to print out the directories search by ld.so with

ldconfig -v 2>/dev/null | grep -v ^$'\t'

ldconfig -v prints out the directories search by the linker (without a leading tab) and the shared libraries found in those directories (with a leading tab); the grep gets the directories. On my machine, this line prints out

/usr/lib64/atlas:
/usr/lib/llvm:
/usr/lib64/llvm:
/usr/lib64/mysql:
/usr/lib64/nvidia:
/usr/lib64/tracker-0.12:
/usr/lib/wine:
/usr/lib64/wine:
/usr/lib64/xulrunner-2:
/lib:
/lib64:
/usr/lib:
/usr/lib64:
/usr/lib64/nvidia/tls: (hwcap: 0x8000000000000000)
/lib/i686: (hwcap: 0x0008000000000000)
/lib64/tls: (hwcap: 0x8000000000000000)
/usr/lib/sse2: (hwcap: 0x0000000004000000)
/usr/lib64/tls: (hwcap: 0x8000000000000000)
/usr/lib64/sse2: (hwcap: 0x0000000004000000)

The first paths, without hwcap in the line, are either built-in or read from /etc/ld.so.conf. The linker can then search additional directories under the basic library search path, with names like sse2 corresponding to additional CPU capabilities. These paths, with hwcap in the line, can contain additional libraries tailored for these CPU capabilities.

One final note: using -p instead of -v above searches the ld.so cache instead.

If it comes to a simple object tree to key value list mapping, where key might be a dotted path description from the object's root element to the leaf being inspected, it's rather obvious that a tree conversion to a key-value list is comparable to an object to xml mapping. Each element within an XML document has a defined position and can be converted into a path. Therefore I took XStream as a basic and stable conversion tool and replaced the hierarchical driver and writer parts with an own implementation. XStream also comes with a basic path tracking mechanism which - being combined with the other two - strictly leads to a solution being suitable for the task.

To know the format string used by Excel without having to guess it: create an excel file, write a date in cell A1 and format it as you want. Then run the following lines:

FileInputStream fileIn = new FileInputStream("test.xlsx");
Workbook workbook = WorkbookFactory.create(fileIn);
CellStyle cellStyle = workbook.getSheetAt(0).getRow(0).getCell(0).getCellStyle();
String styleString = cellStyle.getDataFormatString();
System.out.println(styleString);

Then copy-paste the resulting string, remove the backslashes (for example d/m/yy\ h\.mm;@ becomes d/m/yy h.mm;@) and use it in the http://poi.apache.org/spreadsheet/quick-guide.html#CreateDateCells code:

CellStyle cellStyle = wb.createCellStyle();
CreationHelper createHelper = wb.getCreationHelper();
cellStyle.setDataFormat(createHelper.createDataFormat().getFormat("d/m/yy h.mm;@"));
cell = row.createCell(1);
cell.setCellValue(new Date());
cell.setCellStyle(cellStyle);

border-style:solid; will override the inset style. Which is what you asked.

border:none will remove the border all together.

border-width:1px will set it up to be kind of like before the background change.

border:1px solid #cccccc is more specific and applies all three, width, style and color.

WARNING Re: A Common Ruby Pattern

This is the key answer: the defined? method. The accepted answer above illustrates this perfectly.

But there is a shark, lurking beneath the waves...

Consider this type of common ruby pattern:

 def method1
    @x ||= method2
 end

 def method2
    nil
 end

method2 always returns nil. The first time you call method1, the @x variable is not set - therefore method2 will be run. and method2 will set @x to nil. That is fine, and all well and good. But what happens the second time you call method1?

Remember @x has already been set to nil. But method2 will still be run again!! If method2 is a costly undertaking this might not be something that you want.

Let the defined? method come to the rescue - with this solution, that particular case is handled - use the following:

  def method1
    return @x if defined? @x
    @x = method2
  end

The devil is in the details: but you can evade that lurking shark with the defined? method.

Try add -H tcp://0.0.0.0:2375(at end of Execstart line) instead of -H 0.0.0.0:2375.

So here is a solution for both your requests in the manner you originally asked for. It will give human readability filesize without the filesize limits everyone is experiencing. Compatible with Win Vista or newer. XP only available if Robocopy is installed. Just drop a folder on this batch file or use the better method mentioned below.

@echo off
setlocal enabledelayedexpansion
set "vSearch=Files :"

For %%i in (%*) do (
    set "vSearch=Files :"
    For /l %%M in (1,1,2) do ( 
        for /f "usebackq tokens=3,4 delims= " %%A in (`Robocopy "%%i" "%%i" /E /L /NP /NDL /NFL ^| find "!vSearch!"`) do (
            if /i "%%M"=="1" (
                set "filecount=%%A"
                set "vSearch=Bytes :"
            ) else (
                set "foldersize=%%A%%B"
            )
        )
    )
    echo Folder: %%~nxi FileCount: !filecount! Foldersize: !foldersize!
    REM remove the word "REM" from line below to output to txt file
    REM echo Folder: %%~nxi FileCount: !filecount! Foldersize: !foldersize!>>Folder_FileCountandSize.txt
)
pause

To be able to use this batch file conveniently put it in your SendTo folder. This will allow you to right click a folder or selection of folders, click on the SendTo option, and then select this batch file.

To find the SendTo folder on your computer simplest way is to open up cmd then copy in this line as is.

explorer C:\Users\%username%\AppData\Roaming\Microsoft\Windows\SendTo

I understand where the problem lies and when I look at the specs its clear that unescaped single quotes should be parsed correctly.

I am using jquery`s jQuery.parseJSON function to parse the JSON string but still getting the parse error when there is a single quote in the data that is prepared with json_encode.

Could it be a mistake in my implementation that looks like this (PHP - server side):

$data = array();

$elem = array();
$elem['name'] = 'Erik';
$elem['position'] = 'PHP Programmer';
$data[] = json_encode($elem);

$elem = array();
$elem['name'] = 'Carl';
$elem['position'] = 'C Programmer';
$data[] = json_encode($elem);

$jsonString = "[" . implode(", ", $data) . "]";

The final step is that I store the JSON encoded string into an JS variable:

<script type="text/javascript">
employees = jQuery.parseJSON('<?=$marker; ?>');
</script>

If I use "" instead of '' it still throws an error.

SOLUTION:

The only thing that worked for me was to use bitmask JSON_HEX_APOS to convert the single quotes like this:

json_encode($tmp, JSON_HEX_APOS);

Is there another way of tackle this issue? Is my code wrong or poorly written?

Thanks

Simplest I could come up...

function resizeResizeableHeight() {
    $('.resizableHeight').each( function() {
        $(this).outerHeight( $(this).parent().height() - ( $(this).offset().top - ( $(this).parent().offset().top + parseInt( $(this).parent().css('padding-top') ) ) ) )
    });
}

Now all you have to do is add the resizableHeight class to everything you want to autosize (to it's parent).

You need to add .toArray() to the end of your .map() function

$("#merge_button").click(function(event){
    event.preventDefault();
    var searchIDs = $("#find-table input:checkbox:checked").map(function(){
        return $(this).val();
    }).toArray();
    console.log(searchIDs);
});

Demo: http://jsfiddle.net/sZQtL/

your .key file contains illegal characters. you can check .key file like this:

# file server.key

output "server.key: UTF-8 Unicode (with BOM) text" means it is a plain text, not a key file. The correct output should be "server.key: PEM RSA private key".

use below command to remove illegal characters:

# tail -c +4 server.key > new_server.key

The new_server.key should be correct.

"use strict" makes JavaScript code to run in strict mode, which basically means everything needs to be defined before use. The main reason for using strict mode is to avoid accidental global uses of undefined methods.

Also in strict mode, things run faster, some warnings or silent warnings throw fatal errors, it's better to always use it to make a neater code.

"use strict" is widely needed to be used in ECMA5, in ECMA6 it's part of JavaScript by default, so it doesn't need to be added if you're using ES6.

Look at these statements and examples from MDN:

The "use strict" Directive
The "use strict" directive is new in JavaScript 1.8.5 (ECMAScript version 5). It is not a statement, but a literal expression, ignored by earlier versions of JavaScript. The purpose of "use strict" is to indicate that the code should be executed in "strict mode". With strict mode, you can not, for example, use undeclared variables.

Examples of using "use strict":
Strict mode for functions: Likewise, to invoke strict mode for a function, put the exact statement "use strict"; (or 'use strict';) in the function's body before any other statements.

1) strict mode in functions

 function strict() {
     // Function-level strict mode syntax
     'use strict';
     function nested() { return 'And so am I!'; }
     return "Hi!  I'm a strict mode function!  " + nested();
 }
 function notStrict() { return "I'm not strict."; }

 console.log(strict(), notStrict());

2) whole-script strict mode

'use strict';
var v = "Hi! I'm a strict mode script!";
console.log(v);

3) Assignment to a non-writable global

'use strict';

// Assignment to a non-writable global
var undefined = 5; // throws a TypeError
var Infinity = 5; // throws a TypeError

// Assignment to a non-writable property
var obj1 = {};
Object.defineProperty(obj1, 'x', { value: 42, writable: false });
obj1.x = 9; // throws a TypeError

// Assignment to a getter-only property
var obj2 = { get x() { return 17; } };
obj2.x = 5; // throws a TypeError

// Assignment to a new property on a non-extensible object.
var fixed = {};
Object.preventExtensions(fixed);
fixed.newProp = 'ohai'; // throws a TypeError

You can read more on MDN.

For me, the issue was that I had two emulators with the same name (I created it, deleted it, and then created it again with the same name). There were two emulator entries in the logcat dropdown and it was connected to the wrong one. All I had to do was switch to the other one. I prevented the problem permanently by renaming the emulator.

You can write the where clause as:

where (case when (:stateCode = '') then (1)
            when (:stateCode != '') and (vw.state_cd in (:stateCode)) then 1
            else 0)
       end) = 1;

Alternatively, remove the case entirely:

where (:stateCode = '') or
      ((:stateCode != '') and vw.state_cd in (:stateCode));

Or, even better:

where (:stateCode = '') or vw.state_cd in (:stateCode)

It is the ternary conditional operator.

If the condition in the parenthesis before the ? is true, it returns the value to the left of the :, otherwise the value to the right.

The following CSS only solution for truncating text on a single line works with all browers listed at http://www.caniuse.com as of writing with the exception of Firefox 6.0. Note that JavaScript is totally unnecessary unless you need to support wrapping multiline text or earlier versions of Firefox.

.ellipsis {
    white-space: nowrap;
    overflow: hidden;
    text-overflow: ellipsis;
    -o-text-overflow: ellipsis;
}

If you need support for earlier versions of Firefox check out my answer on this other question.

This is not directly to your code sample, but in general about the error. I'm writing it here, because Google directs this error to this question, so it may be useful for the other devs.

Another use case when you can receive such error is when you're adding a selector to method in another class, eg:

private class MockTextFieldTarget {
private(set) var didCallDoneAction = false
    @objc func doneActionHandler() {
        didCallDoneAction = true
    }
}

And then in another class:

final class UITextFieldTests: XCTestCase {
    func testDummyCode() {
        let mockTarget = MockTextFieldTarget()
        UIBarButtonItem(barButtonSystemItem: .cancel, target: mockTarget, action: MockTextFieldTarget.doneActionHandler)
        // ... do something ...
    }
}

If in the last line you'd simply call #selector(cancelActionHandler) instead of #selector(MockTextFieldTarget.cancelActionHandler), you'd get

use of unresolved identifier

error.

This seems to be an Eclipse bug, though restarting Eclipse worked great for me, hope this helps somebody else too.

To add to Alan Wells's elaborate answer here is a quick fix

Run a Local Server

you can serve any folder in your computer with Serve

First, navigate using the command line into the folder you'd like to serve.

Then

npx i -g serve
serve

or if you'd like to test Serve without downloading it

npx serve

and that's it! You can view your files at http://localhost:5000

I have a sample

import * as types from '../../helpers/ActionTypes';

var initialState = {
  changedValues: {}
};
const quickEdit = (state = initialState, action) => {

  switch (action.type) {

    case types.PRODUCT_QUICKEDIT:
      {
        const item = action.item;
        const changedValues = {
          ...state.changedValues,
          [item.id]: item,
        };

        return {
          ...state,
          loading: true,
          changedValues: changedValues,
        };
      }
    default:
      {
        return state;
      }
  }
};

export default quickEdit;

Try This.

View:

@using (Html.BeginForm("Login", "Accounts", FormMethod.Post)) 
{
   <input type="text" name="IP" id="IP" />
   <input type="text" name="Name" id="Name" />

   <input type="submit" value="Login" />
}

Controller:

[HttpPost]
public ActionResult Login(string IP, string Name)
{
    string s1=IP;//
    string s2=Name;//
}

If you can use model class

[HttpPost]
public ActionResult Login(ModelClassName obj)
{
    string s1=obj.IP;//
    string s2=obj.Name;//
}

Thank you WiredPrairie!

Just to expand on your answer a bit, here is a complete example of defining a constants class.

// CYConstants.ts

class CYConstants {
    public static get NOT_FOUND(): number    { return -1; }
    public static get EMPTY_STRING(): string { return ""; }
}

export = CYConstants;

To use

// main.ts

import CYConstants = require("./CYConstants");

console.log(CYConstants.NOT_FOUND);    // Prints -1
console.log(CYConstants.EMPTY_STRING); // Prints "" (Nothing!)

From a "sniff the network packet" point of view a GET request is safe, as the browser will first establish the secure connection and then send the request containing the GET parameters. But GET url's will be stored in the users browser history / autocomplete, which is not a good place to store e.g. password data in. Of course this only applies if you take the broader "Webservice" definition that might access the service from a browser, if you access it only from your custom application this should not be a problem.

So using post at least for password dialogs should be preferred. Also as pointed out in the link littlegeek posted a GET URL is more likely to be written to your server logs.

For the sake of completeness, there is another approach wrap() or wrapAll() mentioned in this article. So the OP's question could possibly be solved by this (that is, assuming the <div id="destination" /> does not yet exist, the following approach will create such a wrapper from scratch - the OP was not clear about whether the wrapper already exists or not):

$("#source").wrap('<div id="destination" />')
// or
$(".source").wrapAll('<div id="destination" />')

It sounds promising. However, when I was trying to do $("[id^=row]").wrapAll("<fieldset></fieldset>") on multiple nested structure like this:

<div id="row1">
    <label>Name</label>
    <input ...>
</div>

It correctly wraps those <div>...</div> and <input>...</input> BUT SOMEHOW LEAVES OUT the <label>...</label>. So I ended up use the explicit $("row1").append("#a_predefined_fieldset") instead. So, YMMV.

You can set the spinner prompt:

spinner.setPrompt("Select gender...");

Unfortunately, no. This feature is not available for facebook albums.

Easiest way to clear/reset the text field on click is to clear/reset the scope

<input type="text" class="form-control" ng-model="searchAll" ng-click="clearfunction(this)"/>

In Controller

$scope.clearfunction=function(event){
   event.searchAll=null;
}

In my experience the pythonw.exe is faster at least with using pygame.

Try trimming the string to make sure there is no extra white space:

Cursor c = db.rawQuery("SELECT * FROM tbl1 WHERE TRIM(name) = '"+name.trim()+"'", null);

Also use c.moveToFirst() like @thinksteep mentioned.

This is a complete code for select statements.

SQLiteDatabase db = this.getReadableDatabase();
Cursor c = db.rawQuery("SELECT column1,column2,column3 FROM table ", null);
if (c.moveToFirst()){
    do {
        // Passing values 
        String column1 = c.getString(0);
        String column2 = c.getString(1);
        String column3 = c.getString(2); 
        // Do something Here with values
    } while(c.moveToNext());
}
c.close();
db.close();

The WHERE clause is evaluated after the JOIN conditions have been processed.

Try this one. It replaces all the matches with a -.

String str = "helloslkhellodjladfjhello";
String findStr = "hello";
int numberOfMatches = 0;
while (str.contains(findStr)){
    str = str.replaceFirst(findStr, "-");
    numberOfMatches++;
}

And if you don't want to destroy your str you can create a new string with the same content:

String str = "helloslkhellodjladfjhello";
String strDestroy = str;
String findStr = "hello";
int numberOfMatches = 0;
while (strDestroy.contains(findStr)){
    strDestroy = strDestroy.replaceFirst(findStr, "-");
    numberOfMatches++;
}

After executing this block these will be your values:

str = "helloslkhellodjladfjhello"
strDestroy = "-slk-djladfj-"
findStr = "hello"
numberOfMatches = 3

My first impulse was to google for "php math" and I discovered that there's a core math library function called "round()" that likely is what you want.

It seems you may be more comfortable with developing in PHP you let this hold you back from utilizing the full potential with web applications.

It is indeed possible to have PHP render partials and whole views, but I would not recommend it.

To fully utilize the possibilities of HTML and javascript to make a web application, that is, a web page that acts more like an application and relies heavily on client side rendering, you should consider letting the client maintain all responsibility of managing state and presentation. This will be easier to maintain, and will be more user friendly.

I would recommend you to get more comfortable thinking in a more API centric approach. Rather than having PHP output a pre-rendered view, and use angular for mere DOM manipulation, you should consider having the PHP backend output the data that should be acted upon RESTFully, and have Angular present it.

Using PHP to render the view:

/user/account

if($loggedIn)
{
    echo "<p>Logged in as ".$user."</p>";
}
else
{
    echo "Please log in.";
}

How the same problem can be solved with an API centric approach by outputting JSON like this:

api/auth/

{
  authorized:true,
  user: {
      username: 'Joe', 
      securityToken: 'secret'
  }
}

and in Angular you could do a get, and handle the response client side.

$http.post("http://example.com/api/auth", {})
.success(function(data) {
    $scope.isLoggedIn = data.authorized;
});

To blend both client side and server side the way you proposed may be fit for smaller projects where maintainance is not important and you are the single author, but I lean more towards the API centric way as this will be more correct separation of conserns and will be easier to maintain.

UCanAccess is a pure Java JDBC driver that allows us to read from and write to Access databases without using ODBC. It uses two other packages, Jackcess and HSQLDB, to perform these tasks. The following is a brief overview of how to get it set up.

Option 1: Using Maven

If your project uses Maven you can simply include UCanAccess via the following coordinates:

groupId: net.sf.ucanaccess
artifactId: ucanaccess

The following is an excerpt from pom.xml, you may need to update the <version> to get the most recent release:

  <dependencies>
    <dependency>
        <groupId>net.sf.ucanaccess</groupId>
        <artifactId>ucanaccess</artifactId>
        <version>4.0.4</version>
    </dependency>
  </dependencies>

Option 2: Manually adding the JARs to your project

As mentioned above, UCanAccess requires Jackcess and HSQLDB. Jackcess in turn has its own dependencies. So to use UCanAccess you will need to include the following components:

UCanAccess (ucanaccess-x.x.x.jar)
HSQLDB (hsqldb.jar, version 2.2.5 or newer)
Jackcess (jackcess-2.x.x.jar)
commons-lang (commons-lang-2.6.jar, or newer 2.x version)
commons-logging (commons-logging-1.1.1.jar, or newer 1.x version)

Fortunately, UCanAccess includes all of the required JAR files in its distribution file. When you unzip it you will see something like

ucanaccess-4.0.1.jar  
  /lib/
    commons-lang-2.6.jar  
    commons-logging-1.1.1.jar  
    hsqldb.jar  
    jackcess-2.1.6.jar

All you need to do is add all five (5) JARs to your project.

NOTE: Do not add loader/ucanload.jar to your build path if you are adding the other five (5) JAR files. The UcanloadDriver class is only used in special circumstances and requires a different setup. See the related answer here for details.

Eclipse: Right-click the project in Package Explorer and choose Build Path > Configure Build Path.... Click the "Add External JARs..." button to add each of the five (5) JARs. When you are finished your Java Build Path should look something like this

NetBeans: Expand the tree view for your project, right-click the "Libraries" folder and choose "Add JAR/Folder...", then browse to the JAR file.

After adding all five (5) JAR files the "Libraries" folder should look something like this:

IntelliJ IDEA: Choose File > Project Structure... from the main menu. In the "Libraries" pane click the "Add" (+) button and add the five (5) JAR files. Once that is done the project should look something like this:

That's it!

Now "U Can Access" data in .accdb and .mdb files using code like this

// assumes...
//     import java.sql.*;
Connection conn=DriverManager.getConnection(
        "jdbc:ucanaccess://C:/__tmp/test/zzz.accdb");
Statement s = conn.createStatement();
ResultSet rs = s.executeQuery("SELECT [LastName] FROM [Clients]");
while (rs.next()) {
    System.out.println(rs.getString(1));
}

Disclosure

At the time of writing this Q&A I had no involvement in or affiliation with the UCanAccess project; I just used it. I have since become a contributor to the project.

ImmediateParentClass.frotz(self)

will be just fine, whether the immediate parent class defined frotz itself or inherited it. super is only needed for proper support of multiple inheritance (and then it only works if every class uses it properly). In general, AnyClass.whatever is going to look up whatever in AnyClass's ancestors if AnyClass doesn't define/override it, and this holds true for "child class calling parent's method" as for any other occurrence!

If you know the dimensions of your image, then adding a border to the UIImageView's layer is the best solution AFAIK. Infact, you can simply setFrame your imageView to x,y,image.size.width,image.size.height

In case you have an ImageView of a fixed size with dynamically loaded images which are getting resized (or scaled to AspectFit), then your aim is to resize the imageview to the new resized image.

The shortest way to do this:

// containerView is my UIImageView
containerView.layer.borderWidth = 7;
containerView.layer.borderColor = [UIColor colorWithRed:0.22 green:0.22 blue:0.22 alpha:1.0].CGColor;

// this is the key command
[containerView setFrame:AVMakeRectWithAspectRatioInsideRect(image.size, containerView.frame)];

But to use the AVMakeRectWithAspectRatioInsideRect, you need to add this

#import <AVFoundation/AVFoundation.h>

import statement to your file and also include the AVFoundation framework in your project (comes bundled with the SDK).

To fix this, you must review your PHP.INI, and the mail services setup you have in your server.

But my best advice for you is to forget about the mail() function. It depends on PHP.INI settings, it's configuration is different depending on the platform (Linux or Windows), and it can't handle SMTP authentication, which is a big trouble in current days. Too much headache.

Use "PHP Mailer" instead (https://github.com/PHPMailer/PHPMailer), it's a PHP class available for free, and it can handle almost any SMTP server, internal or external, with or without authentication, it works exactly the same way on Linux and Windows, and it won't depend on PHP.INI settings. It comes with many examples, it's very powerful and easy to use.

In case anyone wants to have a responsive flexbox with percentages (%) it is much easier for media queries.

flex-basis: 25%;

This will be a lot smoother when testing.

// VARIABLES

In case someone is looking for a way to comment multiple lines in a html template in Ruby on Rails, there might be a problem with =begin =end, for instance:

<%
=begin
%>
  ... multiple HTML lines to comment out
  <%= image_tag("image.jpg") %>
<%
=end
%>

will fail because of the %> closing the image_tag.

In this case, maybe it is arguable whether this is commenting out or not, but I prefer to enclose the undesired section with an "if false" block:

<% if false %>
  ... multiple HTML lines to comment out
  <%= image_tag("image.jpg") %>
<% end %>

This will work.

One of the data columns in the excel (Column Id 6) has one or more cell data that exceed the datacolumn datatype length in the database.

Verify the data in excel. Also verify the data in the excel for its format to be in compliance with the database table schema.

To avoid this, try exceeding the data-length of the string datatype in the database table.

Hope this helps.

If you really want them to have ALL rights:

use YourDatabase
go

go

This error means Java is not properly installed .

1) brew cask install java (No need to install cask separately it comes with brew)

2) java -version

java version "1.8.0_131"
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)

P.S - What is brew-cask ? Homebrew-Cask extends Homebrew , and solves the hassle of executing an extra command - “To install, drag this icon…” after installing a Application using Homebrew.

N.B - This problem is not specific to Mavericks , you will get it almost all the OS X, including EL Capitan.

Since you are using Java, printf is available from version 1.5

You may use it like this

System.out.printf("%03d ", x);

For Example:

System.out.printf("%03d ", 5);
System.out.printf("%03d ", 55);
System.out.printf("%03d ", 555);

Will Give You

005 055 555

as output

See: System.out.printf and Format String Syntax

Like this... I used it to read Chinese characters...

Dim reader as StreamReader = My.Computer.FileSystem.OpenTextFileReader(filetoimport.Text)
Dim a as String

Do
   a = reader.ReadLine
   '
   ' Code here
   '
Loop Until a Is Nothing

reader.Close()

As an update,appears that on windows clock() measures wall clock time (with CLOCKS_PER_SEC precision)

 http://msdn.microsoft.com/en-us/library/4e2ess30(VS.71).aspx

while on Linux it measures cpu time across cores used by current process

http://www.manpagez.com/man/3/clock

and (it appears, and as noted by the original poster) actually with less precision than CLOCKS_PER_SEC, though maybe this depends on the specific version of Linux.

If you have an array, you can also use numpy.diff:

import numpy as np
a = [1,5,6,8]
np.diff(a)
Out: array([4, 1, 2])

This is the basic skeleton that I always use for this. It makes it easy to implement timeouts and is able to deal with inevitable hanging processes.

import subprocess
import threading
import Queue

def t_read_stdout(process, queue):
    """Read from stdout"""

    for output in iter(process.stdout.readline, b''):
        queue.put(output)

    return

process = subprocess.Popen(['dir'],
                           stdout=subprocess.PIPE,
                           stderr=subprocess.STDOUT,
                           bufsize=1,
                           cwd='C:\\',
                           shell=True)

queue = Queue.Queue()
t_stdout = threading.Thread(target=t_read_stdout, args=(process, queue))
t_stdout.daemon = True
t_stdout.start()

while process.poll() is None or not queue.empty():
    try:
        output = queue.get(timeout=.5)

    except Queue.Empty:
        continue

    if not output:
        continue

    print(output),

t_stdout.join()

Check that you have the latest version of the SDK installed in either C:\Program Files\Java or C:\Program Files (x86)\Java

Then go to VS2015 and follow the path tools - options - Xamarin - Android settings and in the section JDK location select change and go to look for the version you have either x64 or x32.

In a ColdFusion environment, one thing that will cause an error, even with well-formed JSON, is having Enable Request Debugging Output turned on in the ColdFusion Administrator (under Debugging & Logging > Debug Output Settings). Debugging information will be returned with the JSON data and will thus make it invalid.

I created a div element which has the same size as the image and is positioned on top of the image. Then, the mouse events do not go to the image element.

In Powershell 3.0 and above there is both a Invoke-WebRequest and Invoke-RestMethod. Curl is actually an alias of Invoke-WebRequest in PoSH. I think using native Powershell would be much more appropriate than curl, but it's up to you :).

Invoke-WebRequest MSDN docs are here: https://technet.microsoft.com/en-us/library/hh849901.aspx?f=255&MSPPError=-2147217396

Invoke-RestMethod MSDN docs are here: https://technet.microsoft.com/en-us/library/hh849971.aspx?f=255&MSPPError=-2147217396

One interesting way is by using array_keys():

foreach (array_keys($messages, 401, true) as $key) {
    unset($messages[$key]);
}

The array_keys() function takes two additional parameters to return only keys for a particular value and whether strict checking is required (i.e. using === for comparison).

This can also remove multiple array items with the same value (e.g. [1, 2, 3, 3, 4]).

One of the simple way of using NullSafe Comparator is to use Spring implementation of it, below is one of the simple example to refer :

public int compare(Object o1, Object o2) {
        ValidationMessage m1 = (ValidationMessage) o1;
        ValidationMessage m2 = (ValidationMessage) o2;
        int c;
        if (m1.getTimestamp() == m2.getTimestamp()) {
            c = NullSafeComparator.NULLS_HIGH.compare(m1.getProperty(), m2.getProperty());
            if (c == 0) {
                c = m1.getSeverity().compareTo(m2.getSeverity());
                if (c == 0) {
                    c = m1.getMessage().compareTo(m2.getMessage());
                }
            }
        }
        else {
            c = (m1.getTimestamp() > m2.getTimestamp()) ? -1 : 1;
        }
        return c;
    }

None of these answers did not work for me with visual studio 2017.

Tested and approved:

There is no such method as slideLeft() and slideRight() which looks like slideUp() and slideDown(), but you can simulate these effects using jQuery’s animate() function.

HTML Code:

<div class="text">Lorem ipsum.</div>

JQuery Code:

  $(document).ready(function(){
    var DivWidth = $(".text").width();
    $(".left").click(function(){
      $(".text").animate({
        width: 0
      });
    });
    $(".right").click(function(){
      $(".text").animate({
        width: DivWidth
      });
    });
  });

You can see an example here: How to slide toggle a DIV from Left to Right?

I think the answer in the link below is better

Apart from fixing the imports, do a fresh maven clean compile -U. Note the -U option, that brings in new dependencies which sometimes the editor has hard time with. Let the compilation fail due to un-imported classes, but at least you have an option to import them after the maven command.

Just doing Maven->Reimport from Intellij did not work for me.

Trying http://0.0.0.0:3000/routes on a Rails 5 API app (i.e.: JSON-only oriented) will (as of Rails beta 3) return

{"status":404,"error":"Not Found","exception":"#> 
<ActionController::RoutingError:...

However, http://0.0.0.0:3000/rails/info/routes will render a nice, simple HTML page with routes.

If you're using spring-boot-starter-parent in your pom, you simply add the following to your pom:

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

Then do your mvn package.

See this Spring docs page.

A very important aspect here is to mention that the directory structure has to be src/main/java/nameofyourpackage

from cStringIO import StringIO # Python3 use: from io import StringIO
import sys

old_stdout = sys.stdout
sys.stdout = mystdout = StringIO()

# blah blah lots of code ...

sys.stdout = old_stdout

# examine mystdout.getvalue()

You can add android:layoutDirection="rtl" but it's only available with API 17.

I agree with the Hamed elahi and Glorfindel.

My suggestion to add is you can delete and update using aliases

/* 
  given a table bi_customer_actions
  with a field bca_delete_flag of tinyint or bit
    and a field bca_add_date of datetime

  note: the *if 1=1* structure allows me to fold them and turn them on and off
 */
declare
        @Nrows int = 1000

if 1=1 /* testing the inner select */
begin
  select top (@Nrows) * 
    from bi_customer_actions
    where bca_delete_flag = 1
    order by bca_add_date
end

if 1=1 /* delete or update or select */
begin
  --select bca.*
  --update bca  set bca_delete_flag = 0
  delete bca
    from (
      select top (@Nrows) * 
        from bi_customer_actions
        where bca_delete_flag = 1
        order by bca_add_date
    ) as bca
end 

Use the -e argument and the escape character \n:

echo -e "This will generate a next line \nThis new line is the result"

Try adding to td:

display: -webkit-box; // to make td as block
word-break: break-word; // to make content justify

overflowed tds will align with new row.

Just Try This :

textfield.addKeyListener(new java.awt.event.KeyAdapter() {
    public void keyTyped(java.awt.event.KeyEvent evt) {
        if(textfield.getText().length()>=5&&!(evt.getKeyChar()==KeyEvent.VK_DELETE||evt.getKeyChar()==KeyEvent.VK_BACK_SPACE)) {
            getToolkit().beep();
            evt.consume();
         }
     }
});

You just need the lines of code as below:

   try {
        String myjsonString = "{\"phonetype\":\"N95\",\"cat\":\"WP\"}";
        JSONObject jsonObject = new JSONObject(myjsonString );
        //displaying the JSONObject as a String
        Log.d("JSONObject = ", jsonObject.toString());
        //getting specific key values
        Log.d("phonetype = ", jsonObject.getString("phonetype"));
        Log.d("cat = ", jsonObject.getString("cat");
    }catch (Exception ex) {
         StringWriter stringWriter = new StringWriter();
         ex.printStackTrace(new PrintWriter(stringWriter));
         Log.e("exception ::: ", stringwriter.toString());
    }

I used pip version 9.0.1 and had the same issue, all the answers above didn't solve the problem, and I couldn't install python / pip with brew for other reasons.

Upgrading pip to 9.0.3 solved the problem. And because I couldn't upgrade pip with pip I downloaded the source and installed it manually.

1. Download the correct version of pip from - https://pypi.org/simple/pip/
2. sudo python3 pip-9.0.3.tar.gz - Install pip

Or you can install newer pip with:

curl https://bootstrap.pypa.io/get-pip.py | python

JavaScript is a client-side language and your MySQL database is going to be running on a server.

So you have to rename your file to index.php for example (.php is important) so you can use php code for that. It is not very difficult, but not directly possible with html.

(Somehow you can tell your server to let the html files behave like php files, but this is not the best solution.)

So after you renamed your file, go to the very top, before <html> or <!DOCTYPE html> and type:

<?php
    if($_SERVER['REQUEST_METHOD'] == 'POST') {
        /*Creating variables*/
        $name = $_POST["name"];
        $address = $_POST["address"];
        $age = $_POST["age"];


        $dbhost = "localhost"; /*most of the time it's localhost*/
        $username = "yourusername";
        $password = "yourpassword";
        $dbname = "mydatabase";

        $mysql = mysqli_connect($dbhost, $username, $password, $dbname); //It connects
        $query = "INSERT INTO yourtable (name,address,age) VALUES $name, $address, $age";
        mysqli_query($mysql, $query);
    }
?>
<!DOCTYPE html>
<html>
<head>.......
....
    <form method="post">
        <input name="name" type="text"/>
        <input name="address" type="text"/>
        <input name="age" type="text"/>
    </form>
....

Try something like:

$post_data="dispnumber=567567567&extension=6";
$url="http://xxxxxxxx.xxx/xx/xx";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));   
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
$result = curl_exec($ch);

echo $result;

I was using Postman to test my Laravel API.

I received an error that stated

"SQLSTATE[42S22]: Column not found: 1054 Unknown column" because Laravel was trying to automatically create two columns "created_at" and "updated_at".

I had to enter public $timestamps = false; to my model. Then, I tested again with Postman and saw that an "id" = 0 variable was being created in my database.

I finally had to add public $incrementing false; to fix my API.

Samuel Liew is right. sometimes jquery conflict with the other jqueries. to solve this problem you need to put them in such a order that they may not conflict with each other. do one thing: open your application in google chrome and inspect bottom right corner with red marked errors. which kind of error that is?

Maybe this will help

        var result = string.Empty;
        var splitedBySpace = text.Split(new[]{ ' ' }, StringSplitOptions.RemoveEmptyEntries);
        foreach (var sequence in splitedBySpace)
        {
            // let's check the letters. Sequence can contain even 2 words in camel case
            for (var i = 0; i < sequence.Length; i++)
            {
                var letter = sequence[i].ToString();
                // if the letter is Big or it was spaced so this is a start of another word
                if (letter == letter.ToUpper() || i == 0)
                {
                    // add a space between words
                    result += ' ';
                }
                result += i == 0 ? letter.ToUpper() : letter;
            }
        }            
        return result.Trim();

glob.glob() is definitely the way to do it (as per Ignacio). However, if you do need more complicated matching, you can do it with a list comprehension and re.match(), something like so:

files = [f for f in os.listdir('.') if re.match(r'[0-9]+.*\.jpg', f)]

More flexible, but as you note, less efficient.

Won't you need the ensure the area where you display the Arabic is Right-to-Left orientated also?

e.g.

<p dir="rtl">

no need for the padding or the corners.

here's a sample:

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval" >
    <gradient android:startColor="#FFFF0000" android:endColor="#80FF00FF"
        android:angle="270"/>
</shape>

Its important to mention that once in 4-5 years this method might give a 1 second error, becase of a leap-second (http://www.nist.gov/pml/div688/leapseconds.cfm), and the correct formula for that day would be

(24*60*60 + 1) * 1000

There is a question Are leap seconds catered for by Calendar? and the answer is no.

So, if You're designing super time-dependant software, be careful about this formula.

The answer above (by Janusz) is quite correct, but I personnally don't feel 100% confortable with RelativeLayouts, so I prefer to introduce a 'filler', empty TextView, like this:

<!-- filler -->
<TextView android:layout_height="0dip" 
          android:layout_width="fill_parent"
          android:layout_weight="1" />

before the element that should be at the bottom of the screen.

minimumFontSize has been deprecated with iOS 6. You can use minimumScaleFactor.

yourLabel.adjustsFontSizeToFitWidth=YES;
yourLabel.minimumScaleFactor=0.5;

This will take care of your font size according width of label and text.

The issue is that you are not able to get a connection to MYSQL database and hence it is throwing an error saying that cannot build a session factory.

Please see the error below:

 Caused by: java.sql.SQLException: Access denied for user ''@'localhost' (using password: NO) 

which points to username not getting populated.

Please recheck system properties

dataSource.setUsername(System.getProperty("root"));

some packages seems to be missing as well pointing to a dependency issue:

package org.gjt.mm.mysql does not exist

Please run a mvn dependency:tree command to check for dependencies

This code is from Processing.org an open source Java based IDE. You can find it Processing.org. The Arduino IDE also uses this extension, although they run on a hardware board.

EDIT - And yes it is C syntax, used mostly for art or live media presentations.

Just create a .bat file with the line

hostname

in it. That's it. Windows also supports the hostname command.

You go to your "device manager", find your "network adapters", then should find the virtual wifi adapter, then right click it and enable it. After that, you start your cmd with admin privileges, then try:

netsh wlan start hostednetwork

There's now a doesObjectExist method in the official Java API.

Enjoy!

The structure of your menu code is the issue:

cin >> choice;   // new line character is left in the stream

 switch ( ... ) {
     // We enter the handlers, '\n' still in the stream
 }

cin.ignore();   // Put this right after cin >> choice, before you go on
                // getting input with getline.

You have basically two options:

1. You merge. That is actually quite simple, and a perfectly local operation:

   git checkout b1
   git merge master
   # repeat for b2 and b3
   

   This leaves the history exactly as it happened: You forked from master, you made changes to all branches, and finally you incorporated the changes from master into all three branches.

   git can handle this situation really well, it is designed for merges happening in all directions, at the same time. You can trust it be able to get all threads together correctly. It simply does not care whether branch b1 merges master, or master merges b1, the merge commit looks all the same to git. The only difference is, which branch ends up pointing to this merge commit.

2. You rebase. People with an SVN, or similar background find this more intuitive. The commands are analogue to the merge case:

   git checkout b1
   git rebase master
   # repeat for b2 and b3
   

   People like this approach because it retains a linear history in all branches. However, this linear history is a lie, and you should be aware that it is. Consider this commit graph:

   A --- B --- C --- D <-- master
    \
     \-- E --- F --- G <-- b1
   

   The merge results in the true history:

   A --- B --- C --- D <-- master
    \                 \
     \-- E --- F --- G +-- H <-- b1
   

   The rebase, however, gives you this history:

   A --- B --- C --- D <-- master
                      \
                       \-- E' --- F' --- G' <-- b1
   

   The point is, that the commits E', F', and G' never truly existed, and have likely never been tested. They may not even compile. It is actually quite easy to create nonsensical commits via a rebase, especially when the changes in master are important to the development in b1.

   The consequence of this may be, that you can't distinguish which of the three commits E, F, and G actually introduced a regression, diminishing the value of git bisect.

   I am not saying that you shouldn't use git rebase. It has its uses. But whenever you do use it, you need to be aware of the fact that you are lying about history. And you should at least compile test the new commits.

ok just so you know there is a program out there that's called DroidDraw. It can help you draw objects and try them one on top of the other. I tried your solution but I had animation under the smaller image so that didn't work. But then I tried to place one image in a relative layout that's suppose to be under first and then on top of that I drew the other image that is suppose to overlay and everything worked great. So RelativeLayout, DroidDraw and you are good to go :) Simple, no any kind of jiggery pockery :) and here is a bit of code for ya:

The logo is going to be on top of shazam background image.

<?xml version="1.0" encoding="utf-8"?>

android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android"

<ImageView
android:id="@+id/widget39"
android:layout_width="219px"
android:layout_height="225px"
android:src="@drawable/shazam_bkgd"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true"

</ImageView>
<ImageView

Try setting the system default encoding as utf-8 at the start of the script, so that all strings are encoded using that.

Example -

import sys
reload(sys)
sys.setdefaultencoding('utf-8')

The above should set the default encoding as utf-8 .

This really needs to be added to the documentation, which is why I filed an issue about it a few months ago...

You need some 32-bit binaries, and you have a 64-bit OS version (apparently). Try:

sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 lib32stdc++6

That worked for me on Ubuntu 14.10.

UPDATE 2017-12-16: The details will vary by Linux distro and version. So for example, this answer covers newer Ubuntu versions.

Or could be:

$('input[type=file]').change(function () {
    alert("hola");
});

To be specific: $('input[type=file]#fileUpload1').change(...

But as your system grows in size and functionality... i think that returning always a json is not a bad idea at all. Is more a architectural / "big scale design" matter.

You can think about returing always a JSON with two know fields : code and data. Where code is a numeric code specifying the success of the operation to be done and data is any aditional data related with the operation / service requested.

Come on, when we use a backend a service provider, any service can be checked to see if it worked well.

So i stick, to not let spring manage this, exposing hybrid returning operations (Some returns data other nothing...).. instaed make sure that your server expose a more homogeneous interface. Is more simple at the end of the day.

If the folder is accessible from the browser (not outside the document root of your web server), then you just need to output links to the locations of those files. If they are outside the document root, you will need to have links, buttons, whatever, that point to a PHP script that handles getting the files from their location and streaming to the response.

For anyone else who comes here looking, I'm afraid I'm with @usama sulaiman here.

Using the enqueue function provides a safe way to load style sheets and scripts according to the script dependencies and is WordPress' recommended method of achieving what the original poster was trying to achieve. Just think of all the plugins trying to load their own copy of jQuery for instance; you better hope they're using enqueue :D.

Also, wherever possible create a plugin; as adding custom code to your functions file can be pita if you don't have a back-up and you upgrade your theme and overwrite your functions file in the process.

Having a plugin handle this and other custom functions also means you can switch them off if you think their code is clashing with some other plugin or functionality.

Something along the following in a plugin file is what you are looking for:

<?php
/*
Plugin Name: Your plugin name
Description: Your description
Version: 1.0
Author: Your name
Author URI: 
Plugin URI: 
*/

function $yourJS() {
    wp_enqueue_script(
        'custom_script',
        plugins_url( '/js/your-script.js', __FILE__ ),
        array( 'jquery' )
    );
}
 add_action( 'wp_enqueue_scripts',  '$yourJS' );
 add_action( 'wp_enqueue_scripts', 'prefix_add_my_stylesheet' );

 function prefix_add_my_stylesheet() {
    wp_register_style( 'prefix-style', plugins_url( '/css/your-stylesheet.css', __FILE__ ) );
    wp_enqueue_style( 'prefix-style' );
  }

?>

Structure your folders as follows:

Plugin Folder
  |_ css folder
  |_ js folder
  |_ plugin.php ...contains the above code - modified of course ;D

Then zip it up and upload it to your WordPress installation using your add plugins interface, activate it and Bob's your uncle.

Using the concept from waldyrious's answer, I've created the following solution that also addresses the issue of the video playing behind the image on tab restore or using the browser's back button to come back to the page with the video.

HTML

<div class="js-video-lead">
  <img class="hide" src="link/to/lead/image.jpg" />
  <iframe frameborder="0" height="240" src="https://www.youtube.com/embed/<code here>" width="426"></iframe>
</div>

The "hide" class is from Bootstrap and simply applies display: none; so that the image is not visible on page load if JavaScript is disabled.

JavaScript

function video_lead_play_state(element, active)
{
    var $active = $(element).closest(".js-video-lead").find(".btn-play-active");
    var $default = $(element).closest(".js-video-lead").find(".btn-play-default");

    if (active) {
        $active.show();
        $default.hide();
    } else {
        $active.hide();
        $default.show();
    }
}


$(document).ready(function () {
    // hide the videos and show the images
    var $videos = $(".js-video-lead iframe");
    $videos.hide();
    $(".js-video-lead > img").not(".btn-play").show();

    // position the video holders
    $(".js-video-lead").css("position", "relative");

    // prevent autoplay on load and add the play button
    $videos.each(function (index, video) {
        var $video = $(video);

        // prevent autoplay due to normal navigation
        var url = $video.attr("src");
        if (url.indexOf("&autoplay") > -1) {
            url = url.replace("&autoplay=1", "");
        } else {
            url = url.replace("?autoplay=1", "");
        }
        $video.attr("src", url).removeClass(
            "js-video-lead-autoplay"
        );

        // add and position the play button
        var top = parseInt(parseFloat($video.css("height")) / 2) - 15;
        var left = parseInt(parseFloat($video.css("width")) / 2) - 21;
        var $btn_default = $("<img />").attr("src", "play-default.png").css({
            "position": "absolute",
            "top": top + "px",
            "left": left + "px",
            "z-index": 100
        }).addClass("btn-play btn-play-default");
        var $btn_active = $("<img />").attr("src", "play-active.png").css({
            "display": "none",
            "position": "absolute",
            "top": top + "px",
            "left": left + "px",
            "z-index": 110
        }).addClass("btn-play btn-play-active");
        $(".js-video-lead").append($btn_default).append($btn_active);
    });


    $(".js-video-lead img").on("click", function (event) {
        var $holder = $(this).closest(".js-video-lead");
        var $video = $holder.find("iframe");
        var url = $video.attr("src");
        url += (url.indexOf("?") > -1) ? "&" : "?";
        url += "autoplay=1";
        $video.addClass("js-video-lead-autoplay").attr("src", url);
        $holder.find("img").remove();
        $video.show();
    });

    $(".js-video-lead > img").on("mouseenter", function (event) {
        video_lead_play_state(this, true);
    });

    $(".js-video-lead > img").not(".btn-play").on("mouseleave", function (event) {
        video_lead_play_state(this, false);
    });
});

jQuery is required for this solution and it should work with multiple embedded videos (with different lead images) on the same page.

The code utilizes two images play-default.png and play-active.png which are small (42 x 30) images of the YouTube play button. play-default.png is black with some transparency and is displayed initially. play-active.png is red and is displayed when the user moves the mouse over the image. This mimic's the expected behavior that a normal embedded YouTube video exhibits.

I think this log entry Local package.json exists, but node_modules missing, did you mean to install? has gave me the solution.

npm install && npm run dev

It leaves blank pages so that a new part or chapter start on the right-hand side. You can fix this with the "openany" option for the document class. ;)

To see if a dataframe is empty, I argue that one should test for the length of a dataframe's columns index:

if len(df.columns) == 0: 1

Reason:

According to the Pandas Reference API, there is a distinction between:

• an empty dataframe with 0 rows and 0 columns
• an empty dataframe with rows containing NaN hence at least 1 column

Arguably, they are not the same. The other answers are imprecise in that df.empty, len(df), or len(df.index) make no distinction and return index is 0 and empty is True in both cases.

Examples

Example 1: An empty dataframe with 0 rows and 0 columns

In [1]: import pandas as pd
        df1 = pd.DataFrame()
        df1
Out[1]: Empty DataFrame
        Columns: []
        Index: []

In [2]: len(df1.index)  # or len(df1)
Out[2]: 0

In [3]: df1.empty
Out[3]: True

Example 2: A dataframe which is emptied to 0 rows but still retains n columns

In [4]: df2 = pd.DataFrame({'AA' : [1, 2, 3], 'BB' : [11, 22, 33]})
        df2
Out[4]:    AA  BB
        0   1  11
        1   2  22
        2   3  33

In [5]: df2 = df2[df2['AA'] == 5]
        df2
Out[5]: Empty DataFrame
        Columns: [AA, BB]
        Index: []

In [6]: len(df2.index)  # or len(df2)
Out[6]: 0

In [7]: df2.empty
Out[7]: True

Now, building on the previous examples, in which the index is 0 and empty is True. When reading the length of the columns index for the first loaded dataframe df1, it returns 0 columns to prove that it is indeed empty.

In [8]: len(df1.columns)
Out[8]: 0

In [9]: len(df2.columns)
Out[9]: 2

Critically, while the second dataframe df2 contains no data, it is not completely empty because it returns the amount of empty columns that persist.

Why it matters

Let's add a new column to these dataframes to understand the implications:

# As expected, the empty column displays 1 series
In [10]: df1['CC'] = [111, 222, 333]
         df1
Out[10]:    CC
         0 111
         1 222
         2 333
In [11]: len(df1.columns)
Out[11]: 1

# Note the persisting series with rows containing `NaN` values in df2
In [12]: df2['CC'] = [111, 222, 333]
         df2
Out[12]:    AA  BB   CC
         0 NaN NaN  111
         1 NaN NaN  222
         2 NaN NaN  333
In [13]: len(df2.columns)
Out[13]: 3

It is evident that the original columns in df2 have re-surfaced. Therefore, it is prudent to instead read the length of the columns index with len(pandas.core.frame.DataFrame.columns) to see if a dataframe is empty.

Practical solution

# New dataframe df
In [1]: df = pd.DataFrame({'AA' : [1, 2, 3], 'BB' : [11, 22, 33]})
        df
Out[1]:    AA  BB
        0   1  11
        1   2  22
        2   3  33

# This data manipulation approach results in an empty df
# because of a subset of values that are not available (`NaN`)
In [2]: df = df[df['AA'] == 5]
        df
Out[2]: Empty DataFrame
        Columns: [AA, BB]
        Index: []

# NOTE: the df is empty, BUT the columns are persistent
In [3]: len(df.columns)
Out[3]: 2

# And accordingly, the other answers on this page
In [4]: len(df.index)  # or len(df)
Out[4]: 0

In [5]: df.empty
Out[5]: True

# SOLUTION: conditionally check for empty columns
In [6]: if len(df.columns) != 0:  # <--- here
            # Do something, e.g. 
            # drop any columns containing rows with `NaN`
            # to make the df really empty
            df = df.dropna(how='all', axis=1)
        df
Out[6]: Empty DataFrame
        Columns: []
        Index: []

# Testing shows it is indeed empty now
In [7]: len(df.columns)
Out[7]: 0

Adding a new data series works as expected without the re-surfacing of empty columns (factually, without any series that were containing rows with only NaN):

In [8]: df['CC'] = [111, 222, 333]
         df
Out[8]:    CC
         0 111
         1 222
         2 333
In [9]: len(df.columns)
Out[9]: 1

find -name "*Robert*" \( -name "*.pdf" -o -name "*.jpg" \)

The -o repreents an OR condition and you can add as many as you wish within the braces. So this says to find all files containing the word "Robert" anywhere in their names and whose names end in either "pdf" or "jpg".

Note that you can change the default encoding of the JVM using the confusingly-named property file.encoding.

If your application is particularly sensitive to encodings (perhaps through usage of APIs implying default encodings), then you should explicitly set this on JVM startup to a consistent (known) value.

In order to make the terminal always have the file ~/.bashrc and there put the path you wish to use, by adding:

export PATH=$PATH:/XXX

where XXX is the path that you wish to use.

for adb, here's what i use:

export PATH=$PATH:/home/user/Android/android-sdk-linux_x86/platform-tools/

(where "user" is my user name).

Answering your question directly:

I'm trying to declare a priority_queue of nodes, using bool Compare(Node a, Node b) as the comparator function

What I currently have is:

priority_queue<Node, vector<Node>, Compare> openSet;

For some reason, I'm getting Error:

"Compare" is not a type name

The compiler is telling you exactly what's wrong: Compare is not a type name, but an instance of a function that takes two Nodes and returns a bool.
What you need is to specify the function pointer type:
std::priority_queue<Node, std::vector<Node>, bool (*)(Node, Node)> openSet(Compare)

[This is a late answer addressing the title of the question (since that is what people would encounter when searching) rather than the specifics of OP's question which has already been answered adequately]

Ubound is a bit fragile in that it provides no way to know how many dimensions an array has. You can use error trapping to determine the full layout of an array. The following returns a collection of arrays, one for each dimension. The count property can be used to determine the number of dimensions and their lower and upper bounds can be extracted as needed:

Function Bounds(A As Variant) As Collection
    Dim C As New Collection
    Dim v As Variant, i As Long

    On Error GoTo exit_function
    i = 1
    Do While True
        v = Array(LBound(A, i), UBound(A, i))
        C.Add v
        i = i + 1
    Loop
exit_function:
    Set Bounds = C
End Function

Used like this:

Sub test()
    Dim i As Long
    Dim A(1 To 10, 1 To 5, 4 To 10) As Integer
    Dim B(1 To 5) As Variant
    Dim C As Variant
    Dim sizes As Collection

    Set sizes = Bounds(A)
    Debug.Print "A has " & sizes.Count & " dimensions:"
    For i = 1 To sizes.Count
        Debug.Print sizes(i)(0) & " to " & sizes(i)(1)
    Next i

    Set sizes = Bounds(B)
    Debug.Print vbCrLf & "B has " & sizes.Count & " dimensions:"
    For i = 1 To sizes.Count
        Debug.Print sizes(i)(0) & " to " & sizes(i)(1)
    Next i

    Set sizes = Bounds(C)
    Debug.Print vbCrLf & "C has " & sizes.Count & " dimensions:"
    For i = 1 To sizes.Count
        Debug.Print sizes(i)(0) & " to " & sizes(i)(1)
    Next i
End Sub

Output:

A has 3 dimensions:
1 to 10
1 to 5
4 to 10

B has 1 dimensions:
1 to 5

C has 0 dimensions:

This is not my prefered way to do this, cause of massive CPU consumption.

If that is actually your working code, then just keep it like that. Checking a boolean once a second causes NO measurable CPU load. None whatsoever.

The real problem is that the thread that checks the value may not see a change that has happened for an arbitrarily long time due to caching. To ensure that the value is always synchronized between threads, you need to put the volatile keyword in the variable definition, i.e.

private volatile boolean value;

Note that putting the access in a synchronized block, such as when using the notification-based solution described in other answers, will have the same effect.

I found that as of May, 2012, if you set the frame size so that the minimum pixel area (width • height) is above a certain threshold, it bumps the quality up from 360p to 480p, if you're video is at least 640 x 360.

I've discovered that setting a frame size to 780 x 480 for the embed frame triggers the 480p quality, without distorting the video (scaling up). 640 x 585 also works in this manner. I also used the &hd=1 parameter, but I doubt this has much control if your video is not uploaded in HD (720p or higher).

For instance:

<iframe width="780" height="480" src="http://www.youtube.com/embed/[VIDEO-ID]?rel=0&fs=1&showinfo=0&autohide=1&hd=1"></iframe>

Of course, the drawback is that by setting these static frame dimensions, you will most likely get black bars on the sides or above and below, depending on what you prefer.

If you didn't care about the controls being cut-off, you could go on to use CSS and overflow: hidden to crop the black bars out of the frame, providing you know the exact dimensions of the video.

Hope this helps, and hope the Embed method soon gets discrete quality parameters again one day!

There are a few options here. One is to redirect the output of the command to a file, and then use 'tail' to view new lines that are added to that file in real time.

Another option is to launch your program inside of 'screen', which is a sort-of text-based Terminal application. Screen sessions can be attached and detached, but are nominally meant only to be used by the same user, so if you want to share them between users, it's a big pain in the ass.

I'm using Linux Mint 18.2 of this writing. I had a similar issue; when trying to load myphpadmin, it said: "1045 - Access denied for user 'root'@'localhost' (using password: NO)"

I found the file in the /opt/lampp/phpmyadmin directory. I opened the config.inc.php file with my text editor and typed in the correct password. Saved it, and launched it successfully. Profit!

I was having problems with modifying folders and files, I had to change permission to access all my files in /opt/lampp/ directory. I hope this helps someone in the future.

Depending on how much spacing you need, this might help. That's the only thing remotely related to letter-spacing in the TextView.

Edit: please see @JerabekJakub's response below for an updated, better method to do this starting with api 21 (Lollipop)

Use iloc to access by position (rather than label):

In [11]: df = pd.DataFrame([[1, 2], [3, 4]], ['a', 'b'], ['A', 'B'])

In [12]: df
Out[12]: 
   A  B
a  1  2
b  3  4

In [13]: df.iloc[0]  # first row in a DataFrame
Out[13]: 
A    1
B    2
Name: a, dtype: int64

In [14]: df['A'].iloc[0]  # first item in a Series (Column)
Out[14]: 1

Spring 3 supports ${my.server.port:defaultValue} syntax.

If the width of the contents changes, you'll have to use this bit of code to update each column:

private void ResizeGridViewColumn(GridViewColumn column)
{
    if (double.IsNaN(column.Width))
    {
        column.Width = column.ActualWidth;
    }

    column.Width = double.NaN;
}

You'd have to fire it each time the data for that column updates.

Use the shift method on array

>> x = [4,5,6]
=> [4, 5, 6]                                                            
>> x.shift 
=> 4
>> x                                                                    
=> [5, 6] 

If you want to remove n starting elements you can use x.shift(n)

How about:

prog1 & prog2 && fg

This will:

1. Start prog1.
2. Send it to background, but keep printing its output.
3. Start prog2, and keep it in foreground, so you can close it with ctrl-c.
4. When you close prog2, you'll return to prog1's foreground, so you can also close it with ctrl-c.

If you're using Webpack:

1. Set up bootstrap-loader as described in docs;
2. Install tether.js via npm;
3. Add tether.js to the webpack ProvidePlugin plugin.

webpack.config.js:

plugins: [
        <... your plugins here>,
        new webpack.ProvidePlugin({
            $: "jquery",
            jQuery: "jquery",
            "window.jQuery": "jquery",
            "window.Tether": 'tether'
        })
    ]

In my case I was getting this error trying to use the IS_ROLEMEMBER() function on SQL Server 2008 R2. This function isn't valid prior to SQL Server 2012.

Instead of this function I ended up using

select 1 
from sys.database_principals u 
inner join sys.database_role_members ur 
    on u.principal_id = ur.member_principal_id 
inner join sys.database_principals r 
    on ur.role_principal_id = r.principal_id 
where r.name = @role_name 
and u.name = @username

Significantly more verbose, but it gets the job done.

I needed some formatting logic to be shared across multiple components and as an Angular developer also naturally leaned towards a service.

I shared the logic by putting it in a separate file

function format(input) {
    //convert input to output
    return output;
}

module.exports = {
    format: format
};

and then imported it as a module

import formatter from '../services/formatter.service';

//then in component

    render() {

        return formatter.format(this.props.data);
    }

Better late than never.

I had difficulties reading files line by line in some circumstances. The method below is the best I found, so far, and I recommend it.

Usage: String yourData = LoadData("YourDataFile.txt");

Where YourDataFile.txt is assumed to reside in assets/

 public String LoadData(String inFile) {
        String tContents = "";

    try {
        InputStream stream = getAssets().open(inFile);

        int size = stream.available();
        byte[] buffer = new byte[size];
        stream.read(buffer);
        stream.close();
        tContents = new String(buffer);
    } catch (IOException e) {
        // Handle exceptions here
    }

    return tContents;

 }

You can also reset page number counter:

\setcounter{page}{1}

However, with this technique you get wrong page numbers in Acrobat in the top left page numbers field:

Extract each jar to it's own directory using the jar command with parameters xvf. i.e. jar xvf myjar.jar for each jar.

Then, use the UNIX command diff to compare the two directories. This will show the differences in the directories. You can use diff -r dir1 dir2 two recurse and show the differences in text files in each directory(.xml, .properties, etc).

This will also show if binary class files differ. To actually compare the class files you will have to decompile them as noted by others.

This may be work.

Spaces are horrible in filenames or directory names.

The correct syntax for this is to include every directory name that includes spaces, in double quotes

In my case problem was in css and html layout. Layout was something like html - body - root - ... html and body was overflow: hidden, and root was position: fixed, height: 100vh.

Whith this layout browser tabs on mobile doesnt hide. For solve this I delete overflow: hidden from html and body and delete position: fixed, height: 100vh from root.

public ActionResult ViewNextItem(int? id) makes the id integer a nullable type, no need for string<->int conversions.

HTML code

You can use the https://graph.facebook.com/v3.0/{Place_your_Page_ID here}/feed?fields=id,shares,share_count&access_token={Place_your_access_token_here} to get the shares count.

I'm not a big fan of this method because of the memory usage involved, but if you use the arrays it produces, it isn't such a waste.

public static void ForEachRow<T>(this T[,] list, Action<int, T[]> action)
{
    var len = list.GetLength(0);
    var sub = list.GetLength(1);

    T[] e;
    int i, j;

    for (i = 0; i < len; i++)
    {
        e = new T[sub];

        for (j = 0; j < sub; j++)
        {
            e[j] = list[i, j];
        }

        action(i, e);
    }
}

Implementation:

var list = new[,]{0x0, 0x1, 0x2, 0x4, 0x8};

list.ForEachRow((i, row) =>
{
    for (var j = 0; j < row.Length; j++)
    {
        Console.WriteLine("[{0},{1}]: {2}", i, j, row[j]);
    }
});

The other solution I found is less memory intensive, but will use more CPU, especially when the dimensions of the arrays' entries are larger.

public static void ForEachRow<T>(this T[,] list, Action<int, IEnumerable<T>> action)
{
    var len = list.GetLength(0);
    var sub = list.GetLength(1);

    int i, j;
    IEnumerable<T> e;

    for (i = 0; i < len; i++)
    {
        e = Enumerable.Empty<T>();

        for (j = 0; j < sub; j++)
        {
            e = e.Concat(AsEnumerable(list[i, j]));
        }

        action(i, e);
    }
}

private static IEnumerable<T> AsEnumerable<T>(T add)
{
    yield return add;
}

Implementation:

var list = new[,]{0x0, 0x1, 0x2, 0x4, 0x8};

list.ForEachRow((i, row) =>
{
    var j = 0;

    forrach (var o in row)
    {
        Console.WriteLine("[{0},{1}]: {2}", i, j, o);

        ++j;
    }
});

As a whole, I find the first option to be more intuitive, especially if you want to access the produced array by its indexer.

At the end of the day, this is all just eye candy, neither methods should really be used in favour of directly accessing the source array;

for (var i = 0; i < list.GetLength(0); i++)
{
    foreach (var j = 0; j < list.GetLength(1); j++)
    {
        Console.WriteLine("[{0},{1}]: {2}", i, j, list[i, j]);
    }
}

I eventually used:

weather["Temp"] = weather["Temp"].convert_objects(convert_numeric=True)

It worked just fine, except that I got the following message.

C:\ProgramData\Anaconda3\lib\site-packages\ipykernel_launcher.py:3: FutureWarning:
convert_objects is deprecated.  Use the data-type specific converters pd.to_datetime, pd.to_timedelta and pd.to_numeric.

Instead of:

DOCS="/cygdrive/c/Users/my\ dir/Documents"

Try:

DOCS="/cygdrive/c/Users/my dir/Documents" 

This should work on any POSIX system.

I think you can also execute this command:

select (sysdate-1) PREVIOUS_DATE from dual;

from your query:

Select employee_id, count(*) From Employee 
Where to_char(employee_date_hired, 'DD-MON-YY') > '31-DEC-95' 

i think its not to display the number of employees that are hired after June 20, 1994. if you want show number of employees, you can use:

Select count(*) From Employee 
Where to_char(employee_date_hired, 'YYYMMMDDD') > 19940620 

I think for best practice to compare dates you can use:

employee_date_hired > TO_DATE('20-06-1994', 'DD-MM-YYYY');
or
to_char(employee_date_hired, 'YYYMMMDDD') > 19940620;

They will both write the appropriate end-of-line character(s). In addition to that endl will cause the buffer to be committed. You usually don't want to use endl when doing file I/O because the unnecessary commits can impact performance.

if you are running from inside eclipse with wtp, you should be able to change the port from the "servers" view (window -> show view -> servers)

One way you can do it, is to get the slaves list from the frame that needs to be cleared and destroy or "hide" them according to your needs. To get a clear frame you can do it like this:

from tkinter import *

root = Tk()

def clear():
    list = root.grid_slaves()
    for l in list:
        l.destroy()

Label(root,text='Hello World!').grid(row=0)
Button(root,text='Clear',command=clear).grid(row=1)

root.mainloop()

You should call grid_slaves(), pack_slaves() or slaves() depending on the method you used to add the widget to the frame.

{{ app.user.username|default('') }}

Just present login username for example, filter function default('') should be nice when user is NOT login by just avoid annoying error message.

This is how I define utility method to dump all extras of an Intent.

import java.util.Iterator;
import java.util.Set;
import android.os.Bundle;


public static void dumpIntent(Intent i){

    Bundle bundle = i.getExtras();
    if (bundle != null) {
        Set<String> keys = bundle.keySet();
        Iterator<String> it = keys.iterator();
        Log.e(LOG_TAG,"Dumping Intent start");
        while (it.hasNext()) {
            String key = it.next();
            Log.e(LOG_TAG,"[" + key + "=" + bundle.get(key)+"]");
        }
        Log.e(LOG_TAG,"Dumping Intent end");
    }
}

You may append HTML <br /> in between your lines. Something like:

MyLabel.Text = "SomeText asdfa asd fas df asdf" + "<br />" + "Some more text";

With StringBuilder you can try:

StringBuilder sb = new StringBuilder();
sb.AppendLine("Some text with line one");
sb.AppendLine("Some mpre text with line two");
MyLabel.Text = sb.ToString().Replace(Environment.NewLine, "<br />");

According to Microsoft's documentation

1. On the Tools menu, point to Macro, and then click Macros.

2. In the Macro name box, enter the name of the macro you want to assign to a keyboard shortcut key.

3. Click Options.

4. If you want to run the macro by pressing a keyboard shortcut key, enter a letter in the Shortcut key box. You can use CTRL+ letter (for lowercase letters) or CTRL+SHIFT+ letter (for uppercase letters), where letter is any letter key on the keyboard. The shortcut key cannot use a number or special character, such as @ or #.

   Note: The shortcut key will override any equivalent default Microsoft Excel shortcut keys while the workbook that contains the macro is open.

5. If you want to include a description of the macro, type it in the Description box.

6. Click OK.

7. Click Cancel.

If you're concerned the number of rows that meet the condition may change in the few milliseconds since execution of the query and retrieval of results, you could/should execute the queries inside a transaction:

BEGIN TRAN bogus

SELECT COUNT( my_table.my_col ) AS row_count
FROM my_table
WHERE my_table.foo = 'bar'

SELECT my_table.my_col
FROM my_table
WHERE my_table.foo = 'bar'
ROLLBACK TRAN bogus

This would return the correct values, always.

Furthermore, if you're using SQL Server, you can use @@ROWCOUNT to get the number of rows affected by last statement, and redirect the output of real query to a temp table or table variable, so you can return everything altogether, and no need of a transaction:

DECLARE @dummy INT

SELECT my_table.my_col
INTO #temp_table
FROM my_table
WHERE my_table.foo = 'bar'

SET @dummy=@@ROWCOUNT
SELECT @dummy, * FROM #temp_table

bash 4.2 introduced the -v operator which tests if a name is set to any value, even the empty string.

$ unset a
$ b=
$ c=
$ [[ -v a ]] && echo "a is set"
$ [[ -v b ]] && echo "b is set"
b is set
$ [[ -v c ]] && echo "c is set"
c is set

The solution with guideline works only for this particular case with single line EditText. To make it work for multiline EditText you should use "packed" chain.

<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

For now I took @Gian's advice & limited the number of records per Workbook to 500k and rolled over the rest to the next Workbook. Seems to be working decent. For the above configuration, it took me about 10 mins per workbook.

each JSF component renders itself out to HTML and has complete control over what HTML it produces. There are many tricks that can be used by JSF, and exactly which of those tricks will be used depends on the JSF implementation you are using.

• Ensure that every from input has a totaly unique name, so that when the form gets submitted back to to component tree that rendered it, it is easy to tell where each component can read its value form.
• The JSF component can generate javascript that submitts back to the serer, the generated javascript knows where each component is bound too, because it was generated by the component.

• For things like hlink you can include binding information in the url as query params or as part of the url itself or as matrx parameters. for examples.

  http:..../somelink?componentId=123 would allow jsf to look in the component tree to see that link 123 was clicked. or it could e htp:..../jsf;LinkId=123

The easiest way to answer this question is to create a JSF page with only one link, then examine the html output it produces. That way you will know exactly how this happens using the version of JSF that you are using.

You can do:

hash=$(genhash --use-ssl -s $IP -p 443 --url $URL)

or

hash=`genhash --use-ssl -s $IP -p 443 --url $URL`

If you want to result of the entire pipe to be assigned to the variable, you can use the entire pipeline in the above assignments.

I would like to recommend flask-empty at GitHub.

It provides an easy way to understand Blueprints, multiple views and extensions.

Try docker rmi node. That should work.

Seeing all created containers is as simple as docker ps -a.

To remove all existing containers (not images!) run docker rm $(docker ps -aq)

If your source-file is already utf8 then drop the utf8_* functions. php5 is storing strings as array of byte.

you should add a meta tag for encoding within the html AND you should add an http header which sets the transferencoding to utf-8.

<html>
<head>
   <meta http-equiv="Content-Type" content="text/html; charset=utf-8">

and in php

<?php
header('Content-Type: text/html; charset=utf-8');

Following on from Tomasz's answer, you can also programmatically set the shade of the entire button using the PorterDuff multiply mode. This will change the button colour rather than just the tint.

If you start with a standard grey shaded button:

button.getBackground().setColorFilter(0xFFFF0000, PorterDuff.Mode.MULTIPLY);

will give you a red shaded button,

button.getBackground().setColorFilter(0xFF00FF00, PorterDuff.Mode.MULTIPLY);

will give you a green shaded button etc., where the first value is the colour in hex format.

It works by multiplying the current button colour value by your colour value. I'm sure there's also a lot more you can do with these modes.

This method is deprecated now from now starting with Android Q.

Try This will really help.

if (Build.VERSION.SDK_INT < Build.VERSION_CODES.Q) {// if build version is less than Q try the old traditional method
                    if (!wifiManager.isWifiEnabled()) {
                        wifiManager.setWifiEnabled(true);
                        btnOnOff.setText("Wifi ONN");
                    } else {
                        wifiManager.setWifiEnabled(false);
                        btnOnOff.setText("Wifi OFF");
                    }
                } else {// if it is Android Q and above go for the newer way    NOTE: You can also use this code for less than android Q also
                    Intent panelIntent = new Intent(Settings.Panel.ACTION_WIFI);
                    startActivityForResult(panelIntent, 1);
                }

To do the same I did following in terminal-

$ wget https://dl.pstmn.io/download/latest/linux64 -O postman.tar.gz
$ sudo tar -xzf postman.tar.gz -C /opt
$ rm postman.tar.gz
$ sudo ln -s /opt/Postman/Postman /usr/bin/postman

1. Now open file system, move to /usr/bin/ and search form "Postman"
2. There was a sh file with name 'Postman'
3. Double clicked on it which opened postman.
4. Locked icon to launcher on right clicking its icon for further use.

Hope will hell others too.

Sources that helped me get to work with my self signed certificate on my AWS Apache server and connect with HttpsURLConnection from android device:

SSL on aws instance - amazon tutorial on ssl
Android Security with HTTPS and SSL - creating your own trust manager on client for accepting your certificate
Creating self signed certificate - easy script for creating your certificates

Then I did the following:

1. Made sure the server supports https (sudo yum install -y mod24_ssl)
2. Put this script in a file create_my_certs.sh:

#!/bin/bash
FQDN=$1

# make directories to work from
mkdir -p server/ client/ all/

# Create your very own Root Certificate Authority
openssl genrsa \
  -out all/my-private-root-ca.privkey.pem \
  2048

# Self-sign your Root Certificate Authority
# Since this is private, the details can be as bogus as you like
openssl req \
  -x509 \
  -new \
  -nodes \
  -key all/my-private-root-ca.privkey.pem \
  -days 1024 \
  -out all/my-private-root-ca.cert.pem \
  -subj "/C=US/ST=Utah/L=Provo/O=ACME Signing Authority Inc/CN=example.com"

# Create a Device Certificate for each domain,
# such as example.com, *.example.com, awesome.example.com
# NOTE: You MUST match CN to the domain name or ip address you want to use
openssl genrsa \
  -out all/privkey.pem \
  2048

# Create a request from your Device, which your Root CA will sign
openssl req -new \
  -key all/privkey.pem \
  -out all/csr.pem \
  -subj "/C=US/ST=Utah/L=Provo/O=ACME Tech Inc/CN=${FQDN}"

# Sign the request from Device with your Root CA
openssl x509 \
  -req -in all/csr.pem \
  -CA all/my-private-root-ca.cert.pem \
  -CAkey all/my-private-root-ca.privkey.pem \
  -CAcreateserial \
  -out all/cert.pem \
  -days 500

# Put things in their proper place
rsync -a all/{privkey,cert}.pem server/
cat all/cert.pem > server/fullchain.pem         # we have no intermediates in this case
rsync -a all/my-private-root-ca.cert.pem server/
rsync -a all/my-private-root-ca.cert.pem client/

3. Run bash create_my_certs.sh yourdomain.com

4. Place the certificates in their proper place on the server (you can find configuration in /etc/httpd/conf.d/ssl.conf). All these should be set:
   SSLCertificateFile
   SSLCertificateKeyFile
   SSLCertificateChainFile
   SSLCACertificateFile

5. Restart httpd using sudo service httpd restart and make sure httpd started:
   Stopping httpd: [ OK ]
   Starting httpd: [ OK ]

6. Copy my-private-root-ca.cert to your android project assets folder

7. Create your trust manager:
   

   SSLContext SSLContext;

   CertificateFactory cf = CertificateFactory.getInstance("X.509"); InputStream caInput = context.getAssets().open("my-private-root-ca.cert.pem"); Certificate ca; try { ca = cf.generateCertificate(caInput); } finally { caInput.close(); }

     // Create a KeyStore containing our trusted CAs
     String keyStoreType = KeyStore.getDefaultType();
     KeyStore keyStore = KeyStore.getInstance(keyStoreType);
     keyStore.load(null, null);
     keyStore.setCertificateEntry("ca", ca);
   
     // Create a TrustManager that trusts the CAs in our KeyStore
     String tmfAlgorithm = TrustManagerFactory.getDefaultAlgorithm();
     TrustManagerFactory tmf = TrustManagerFactory.getInstance(tmfAlgorithm);
     tmf.init(keyStore);
   
     // Create an SSLContext that uses our TrustManager
     SSLContext = SSLContext.getInstance("TLS");
     SSSLContext.init(null, tmf.getTrustManagers(), null);
   

8. And make the connection using HttpsURLConnection:

   HttpsURLConnection connection = (HttpsURLConnection) url.openConnection(); connection.setSSLSocketFactory(SSLContext.getSocketFactory());

9. Thats it, try your https connection.

Use Arrays.equals() if you want to compare the actual content of arrays that contain primitive types values (like byte).

System.out.println(Arrays.equals(aa, bb));

Use Arrays.deepEquals for comparison of arrays that contain objects.

To use quotes just for completeness.

If not recursive, remove the /**

Benoit's solution works, but you really don't need to incur the overhead to draw a shape. Since colors can be drawables, just define a color in a /res/values/colors.xml file:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="semitransparent_white">#77ffffff</color>
</resources>

And then use as such in your selector:

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

merge to Map

 let merge = {...map1,...map2};

jQuery doesn't have a convenient function for this. You need to combine contents(), which will give just child nodes but includes text nodes, with find(), which gives all descendant elements but no text nodes. Here's what I've come up with:

var getTextNodesIn = function(el) {
    return $(el).find(":not(iframe)").addBack().contents().filter(function() {
        return this.nodeType == 3;
    });
};

getTextNodesIn(el);

Note: If you're using jQuery 1.7 or earlier, the code above will not work. To fix this, replace addBack() with andSelf(). andSelf() is deprecated in favour of addBack() from 1.8 onwards.

This is somewhat inefficient compared to pure DOM methods and has to include an ugly workaround for jQuery's overloading of its contents() function (thanks to @rabidsnail in the comments for pointing that out), so here is non-jQuery solution using a simple recursive function. The includeWhitespaceNodes parameter controls whether or not whitespace text nodes are included in the output (in jQuery they are automatically filtered out).

Update: Fixed bug when includeWhitespaceNodes is falsy.

function getTextNodesIn(node, includeWhitespaceNodes) {
    var textNodes = [], nonWhitespaceMatcher = /\S/;

    function getTextNodes(node) {
        if (node.nodeType == 3) {
            if (includeWhitespaceNodes || nonWhitespaceMatcher.test(node.nodeValue)) {
                textNodes.push(node);
            }
        } else {
            for (var i = 0, len = node.childNodes.length; i < len; ++i) {
                getTextNodes(node.childNodes[i]);
            }
        }
    }

    getTextNodes(node);
    return textNodes;
}

getTextNodesIn(el);

Simple formula solution: Using dynamic array functions (UNIQUE function)

Since fall 2018, the subscription versions of Microsoft Excel (Office 365 / Microsoft 365 app) contain so called dynamic array functions (not yet available in Office 2016/2019 nonsubscription versions).

UNIQUE function

One of those functions is the UNIQUE function that will deliver an array of unique values for the selected range.

Example

In the following example, the input values are in range A1:A6. The UNIQUE function is typed into cell C1.

=UNIQUE(A1:A6)

As you can see, the UNIQUE function will automatically spill over the necessary range of cells in order to show all unique values. This is indicated by the thin, blue frame around C1:C4.

Good to know

As the UNIQUE function automatically spills over the necessary number of rows, you should leave enough space under the C1. If there is not enough space, you will get a #SPILL error.

If you want to reference the results of the UNIQUE function, you can just reference the cell containing the UNIQUE function and add a hash # sign.

=C1#

It is also possible to check unique values in several columns. In this case, the UNIQUE function will deliver all rows where the combination of the cells within the row are unique:

If you wish to show unique columns instead of unique rows, you have to set the [by_col] argument to TRUE (default is FALSE, meaning you will receive unique rows).

You can also show values that appear exactly once by setting the [exactly_once] argument to TRUE:

=UNIQUE(A1:A6;;TRUE)

If you don't provide Spark configuration in JavaSparkContext then you get this error. That is: JavaSparkContext sc = new JavaSparkContext();

Solution: Provide JavaSparkContext sc = new JavaSparkContext(conf);

Basically, I want to check if a particular string contains AT LEAST day(1 through 31 or 01 through 31),month(1 through 12 or 01 through 12) and year(yyyy or yy) in any order, with any date separator , what will be the solution? So, if the value includes any parts of time, it should return true too. I could NOT be able to define a array of format.

When I was in a similar situation, here is what I did:

1. Gather all the formats my system is expected to support.
2. Looked at what is common or can be generalize.
3. Learned to create REGEX (It is an investment of time initially but pays off once you create one or two on your own). Also do not try to build REGEX for all formats in one go, follow incremental process.
4. I created REGEX to cover as many format as possible.
5. For few cases, not to make REGEX extra complex, I covered it through DateTime.Parse() method.
6. With the combination of both Parse as well as REGEX i was able to validate the input is correct/as expected.

This http://www.codeproject.com/Articles/13255/Validation-with-Regular-Expressions-Made-Simple was really helpful both for understanding as well as validation the syntax for each format.

My 2 cents if it helps....

Refer the example from angularjs documentation how to overcome these issues.

1. Go to this documentation link here
2. Find 'Binding select to a non-string value via ngModel parsing / formatting'
3. There u can see there, directive called 'convertToNumber' solve the issue.

It works for me. Can also see how it works here

So easy way :

XML:

<android.support.design.widget.TabLayout

        android:id="@+id/viewpager"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

Java code:

private ViewPager viewPager;

        "text1",
        "text1",

    super.onCreate(savedInstanceState);
    setContentView(R.layout.layout_a_requests);

    viewPager = findViewById(R.id.viewpager);
    viewPager.setAdapter(new MyPagerAdapter(getSupportFragmentManager()));
    TabLayout tabLayout = findViewById(R.id.tab_layout);
    tabLayout.setSelectedTabIndicatorColor(Color.parseColor("#1f57ff"));
    tabLayout.setSelectedTabIndicatorHeight((int) (4 * 
    getResources().getDisplayMetrics().density));
    tabLayout.setTabTextColors(Color.parseColor("#9d9d9d"), 
    Color.parseColor("#0d0e10"));
    tabLayout.setupWithViewPager(viewPager);
    /***************************************************************************/
    }

What

• A settings file for the server
• Cannot be accessed by end-user
• There is no need to reboot the server, changes work immediately
• It might serve as a bridge between your code and server

We can do

• URL rewriting
• Custom error pages
• Caching
• Redirections
• Blocking ip's

Do you mean that the formatter does not break long lines? Check Settings / Project Settings / Code Style / Wrapping.

Update: in later versions of IntelliJ, the option is under Settings / Editor / Code Style. And select Wrap when typing reaches right margin.

This is answered in some of the answers to Can't find how to use HttpContent as well as in this blog post.

In summary, you can't directly set up an instance of HttpContent because it is an abstract class. You need to use one the classes derived from it depending on your need. Most likely StringContent, which lets you set the string value of the response, the encoding, and the media type in the constructor. See: http://msdn.microsoft.com/en-us/library/system.net.http.stringcontent.aspx

Sometimes you need to reset ADB. To do that, in Eclipse, go:

Window>> Show View >> Android (Might be found in the "Other" option)>>Devices

in the device Tab, click the down arrow, and choose reset adb.

You could also execute tree > tree.txt in both folders and then diff both tree.txt files with any file based diff tool (git diff).

Try to install in your project the NuGet Package: Microsoft.AspNet.WebApi.Client:

Had a similar problem with a ghost table. Thankfully had an SQL dump from before the failure.

In my case, I had to:

1. Stop mySQL
2. Move ib* files from /var/mysql off to a backup
3. Delete /var/mysql/{dbname}
4. Restart mySQL
5. Recreate empty database
6. Restore dump file

NOTE: Requires dump file.

Try the following to see if you have the proper repository installed:

# yum search java | grep 'java-'

This is going to return a list of available packages that have java in the title. Specifically we are interested in the java- anything, as the jdk will typically be in 'java-version#' type format... Anyhow, if you have to install a repo look at Dag Wieers repo:

http://dag.wieers.com/rpm/FAQ.php#B

After you've got it installed try yum search again... This time you'll have a bunch of java stuff.

# yum search java | grep 'java-'

This will return the list of the available java packages. You can install one like this:

# yum install java-1.7.0-openjdk.x86_64

In case of windows: use curl --proxy "" ...

Lists themselves are thread-safe. In CPython the GIL protects against concurrent accesses to them, and other implementations take care to use a fine-grained lock or a synchronized datatype for their list implementations. However, while lists themselves can't go corrupt by attempts to concurrently access, the lists's data is not protected. For example:

L[0] += 1

is not guaranteed to actually increase L[0] by one if another thread does the same thing, because += is not an atomic operation. (Very, very few operations in Python are actually atomic, because most of them can cause arbitrary Python code to be called.) You should use Queues because if you just use an unprotected list, you may get or delete the wrong item because of race conditions.

Add an annotation to the method using the keyword Obsolete. Message argument is optional but a good idea to communicate why the item is now obsolete and/or what to use instead.
Example:

[System.Obsolete("use myMethodB instead")]
void myMethodA()

Arnon Rotem-Gal-Oz already answered this question a while ago, but I thought some may like this slightly more concise version.

LOGS = LOAD 'log';
LOG_COUNT = FOREACH (GROUP LOGS ALL) GENERATE COUNT(LOGS);

You need to put the entire ternary expression in parenthesis. Unfortunately that means you can't use "@:", but you could do something like this:

@(deletedView ? "Deleted" : "Created by")

Razor currently supports a subset of C# expressions without using @() and unfortunately, ternary operators are not part of that set.

If you are using Docker for MAC (not boot2docker) then the location is /Users/<</>UserName></>/Library/Containers/com.docker.docker/Data/

Starting from Jersey 2.x, the MultivaluedMapImpl class is replaced by MultivaluedHashMap. You can use it to add form data and send it to the server:

    WebTarget webTarget = client.target("http://www.example.com/some/resource");
    MultivaluedMap<String, String> formData = new MultivaluedHashMap<String, String>();
    formData.add("key1", "value1");
    formData.add("key2", "value2");
    Response response = webTarget.request().post(Entity.form(formData));

Note that the form entity is sent in the format of "application/x-www-form-urlencoded".

For those searching this error, another thing that can trigger AtributeError: can't set attribute is if you try to set a decorated @property that has no setter method. Not the problem in the OP's question, but I'm putting it here to help any searching for the error message directly. (if you don't like it, go edit the question's title :)

class Test:
    def __init__(self):
        self._attr = "original value"
        # This will trigger an error...
        self.attr = "new value"
    @property
    def attr(self):
        return self._attr

Test()

When you're using Data Type: int you can select the row which you want to get autoincremented and go to the column properties tag. There you can set the identity to 'yes'. The starting value for autoincrement can also be edited there. Hope I could help ;)

Easiest way

make a public static method containing viewpager.setAdapter

make adapter and viewpager static

public static void refreshFragments(){
        viewPager.setAdapter(adapter);
    }

call anywhere, any activity, any fragment.

MainActivity.refreshFragments();

Code in python using the awesome "boto" lib. The code returns a list of files in a bucket and also handles exceptions for missing buckets.

import boto

conn = boto.connect_s3( <ACCESS_KEY>, <SECRET_KEY> )
try:
    bucket = conn.get_bucket( <BUCKET_NAME>, validate = True )
except boto.exception.S3ResponseError, e:
    do_something() # The bucket does not exist, choose how to deal with it or raise the exception

return [ key.name.encode( "utf-8" ) for key in bucket.list() ]

Don't forget to replace the < PLACE_HOLDERS > with your values.

If you create your gems with bundler:

# do this in the proper directory
bundle gem foobar

You can install them with rake after they are written:

# cd into your gem directory
rake install

Chances are, that your downloaded gem will know rake install, too.

Conversion Operators (also known as User Defined Conversions)

In C++ you can create conversion operators, operators that allow the compiler to convert between your types and other defined types. There are two types of conversion operators, implicit and explicit ones.

Implicit Conversion Operators (C++98/C++03 and C++11)

An implicit conversion operator allows the compiler to implicitly convert (like the conversion between int and long) the value of a user-defined type to some other type.

The following is a simple class with an implicit conversion operator:

class my_string {
public:
  operator const char*() const {return data_;} // This is the conversion operator
private:
  const char* data_;
};

Implicit conversion operators, like one-argument constructors, are user-defined conversions. Compilers will grant one user-defined conversion when trying to match a call to an overloaded function.

void f(const char*);

my_string str;
f(str); // same as f( str.operator const char*() )

At first this seems very helpful, but the problem with this is that the implicit conversion even kicks in when it isn’t expected to. In the following code, void f(const char*) will be called because my_string() is not an lvalue, so the first does not match:

void f(my_string&);
void f(const char*);

f(my_string());

Beginners easily get this wrong and even experienced C++ programmers are sometimes surprised because the compiler picks an overload they didn’t suspect. These problems can be mitigated by explicit conversion operators.

Explicit Conversion Operators (C++11)

Unlike implicit conversion operators, explicit conversion operators will never kick in when you don't expect them to. The following is a simple class with an explicit conversion operator:

class my_string {
public:
  explicit operator const char*() const {return data_;}
private:
  const char* data_;
};

Notice the explicit. Now when you try to execute the unexpected code from the implicit conversion operators, you get a compiler error:

prog.cpp: In function ‘int main()’:
prog.cpp:15:18: error: no matching function for call to ‘f(my_string)’
prog.cpp:15:18: note: candidates are:
prog.cpp:11:10: note: void f(my_string&)
prog.cpp:11:10: note:   no known conversion for argument 1 from ‘my_string’ to ‘my_string&’
prog.cpp:12:10: note: void f(const char*)
prog.cpp:12:10: note:   no known conversion for argument 1 from ‘my_string’ to ‘const char*’

To invoke the explicit cast operator, you have to use static_cast, a C-style cast, or a constructor style cast ( i.e. T(value) ).

However, there is one exception to this: The compiler is allowed to implicitly convert to bool. In addition, the compiler is not allowed to do another implicit conversion after it converts to bool (a compiler is allowed to do 2 implicit conversions at a time, but only 1 user-defined conversion at max).

Because the compiler will not cast "past" bool, explicit conversion operators now remove the need for the Safe Bool idiom. For example, smart pointers before C++11 used the Safe Bool idiom to prevent conversions to integral types. In C++11, the smart pointers use an explicit operator instead because the compiler is not allowed to implicitly convert to an integral type after it explicitly converted a type to bool.

Continue to Overloading new and delete.

The warning comes from the fact that you're dereferencing src in the assignment. The expression *src has type char, which is an integral type. The expression "anotherstring" has type char [14], which in this particular context is implicitly converted to type char *, and its value is the address of the first character in the array. So, you wind up trying to assign a pointer value to an integral type, hence the warning. Drop the * from *src, and it should work as expected:

src = "anotherstring";

since the type of src is char *.
