isolation level read committed

This isolation level allows dirty reads. One transaction may see uncommitted changes made by some other transaction.

To maintain the highest level of isolation, a DBMS usually acquires locks on data, which may result in a loss of concurrency and a high locking overhead. This isolation level relaxes this property.

You may want to check out the Wikipedia article on READ UNCOMMITTED for a few examples and further reading.

You may also be interested in checking out Jeff Atwood's blog article on how he and his team tackled a deadlock issue in the early days of Stack Overflow. According to Jeff:

But is nolock dangerous? Could you end up reading invalid data with read uncommitted on? Yes, in theory. You'll find no shortage of database architecture astronauts who start dropping ACID science on you and all but pull the building fire alarm when you tell them you want to try nolock. It's true: the theory is scary. But here's what I think: "In theory there is no difference between theory and practice. In practice there is."

I would never recommend using nolock as a general "good for what ails you" snake oil fix for any database deadlocking problems you may have. You should try to diagnose the source of the problem first.

But in practice adding nolock to queries that you absolutely know are simple, straightforward read-only affairs never seems to lead to problems... As long as you know what you're doing.

One alternative to the READ UNCOMMITTED level that you may want to consider is the READ COMMITTED SNAPSHOT. Quoting Jeff again:

Snapshots rely on an entirely new data change tracking method ... more than just a slight logical change, it requires the server to handle the data physically differently. Once this new data change tracking method is enabled, it creates a copy, or snapshot of every data change. By reading these snapshots rather than live data at times of contention, Shared Locks are no longer needed on reads, and overall database performance may increase.

Simply the answer according to my reading and understanding to this thread and @remus-rusanu answer is based on this simple scenario:

There are two transactions A and B. Transaction B is reading Table X Transaction A is writing in table X Transaction B is reading again in Table X.

• ReadUncommitted: Transaction B can read uncommitted data from Transaction A and it could see different rows based on B writing. No lock at all
• ReadCommitted: Transaction B can read ONLY committed data from Transaction A and it could see different rows based on COMMITTED only B writing. could we call it Simple Lock?
• RepeatableRead: Transaction B will read the same data (rows) whatever Transaction A is doing. But Transaction A can change other rows. Rows level Block
• Serialisable: Transaction B will read the same rows as before and Transaction A cannot read or write in the table. Table-level Block
• Snapshot: every Transaction has its own copy and they are working on it. Each one has its own view

I want to understand the lock each transaction isolation takes on the table

For example, you have 3 concurrent processes A, B and C. A starts a transaction, writes data and commit/rollback (depending on results). B just executes a SELECT statement to read data. C reads and updates data. All these process work on the same table T.

• READ UNCOMMITTED - no lock on the table. You can read data in the table while writing on it. This means A writes data (uncommitted) and B can read this uncommitted data and use it (for any purpose). If A executes a rollback, B still has read the data and used it. This is the fastest but most insecure way to work with data since can lead to data holes in not physically related tables (yes, two tables can be logically but not physically related in real-world apps =\).
• READ COMMITTED - lock on committed data. You can read the data that was only committed. This means A writes data and B can't read the data saved by A until A executes a commit. The problem here is that C can update data that was read and used on B and B client won't have the updated data.
• REPEATABLE READ - lock on a block of SQL(which is selected by using select query). This means B reads the data under some condition i.e. WHERE aField > 10 AND aField < 20, A inserts data where aField value is between 10 and 20, then B reads the data again and get a different result.
• SERIALIZABLE - lock on a full table(on which Select query is fired). This means, B reads the data and no other transaction can modify the data on the table. This is the most secure but slowest way to work with data. Also, since a simple read operation locks the table, this can lead to heavy problems on production: imagine that T table is an Invoice table, user X wants to know the invoices of the day and user Y wants to create a new invoice, so while X executes the read of the invoices, Y can't add a new invoice (and when it's about money, people get really mad, especially the bosses).

I want to understand where we define these isolation levels: only at JDBC/hibernate level or in DB also

Using JDBC, you define it using Connection#setTransactionIsolation.

Using Hibernate:

<property name="hibernate.connection.isolation">2</property>

Where

• 1: READ UNCOMMITTED
• 2: READ COMMITTED
• 4: REPEATABLE READ
• 8: SERIALIZABLE

Hibernate configuration is taken from here (sorry, it's in Spanish).

By the way, you can set the isolation level on RDBMS as well:

• MySQL isolation level,
• SQL Server isolation level
• Informix isolation level (Personal Note: I will never forget about SET ISOLATION TO DIRTY READ sentence.)

and on and on...

if myString?.startIndex != myString?.endIndex {}

or use the blazing fast GNU Parallel:

grep -rl oldtext . | parallel sed -i 's/oldtext/newtext/g' {}

To be able to access the form in your controller, you have to add it to a dummy scope object.

Something like $scope.dummy = {}

For your situation this would mean something like:

<form name="dummy.customerForm">

In your controller you will be able to access the form by:

$scope.dummy.customerForm

and you will be able to do stuff like

$scope.dummy.customerForm.$setPristine()

Having a '.' in your models will ensure that prototypal inheritance is in play. So, use <input type="text" ng-model="someObj.prop1"> rather than <input type="text" ng-model="prop1">

If you really want/need to use a primitive, there are two workarounds:

1.Use $parent.parentScopeProperty in the child scope. This will prevent the child scope from creating its own property. 2.Define a function on the parent scope, and call it from the child, passing the primitive value up to the parent (not always possible)

I have build a Linq library for TypeScript under TsLinq.codeplex.com that you can use for plain javascript too. That library is 2-3 times faster than Linq.js and contains unit tests for all Linq methods. Maybe you could review that one.

I would like to add something to the very helpful answer above. If you don't know the height you'll end up with since your views .getHeight() returns 0 you can do the following to get the height:

contentView.measure(DUMMY_HIGH_DIMENSION, DUMMY_HIGH_DIMENSION);
int finalHeight = view.getMeasuredHeight();

Where DUMMY_HIGH_DIMENSIONS is the width/height (in pixels) your view is constrained to ... having this a huge number is reasonable when the view is encapsulated with a ScrollView.

I've seen your code in web.php as follows: Route::post('/edit/{id}','ProjectController@update');

Step 1: remove the {id} random parameter so it would be like this: Route::post('/edit','ProjectController@update');

Step 2: Then remove the @method('PUT') in your form, so let's say we'll just plainly use the POST method

Then how can I pass the ID to my method?

Step 1: make an input field in your form with the hidden attribute for example

<input type="hidden" value="{{$project->id}}" name="id">

Step 2: in your update method in your controller, fetch that ID for example:

$id = $request->input('id');

then you may not use it to find which project to edit

$project = Project::find($id)
//OR
$project = Project::where('id',$id);

You can also do it this way to reference the previous branch implicitly:

git checkout mainline
git pull
git merge -
git push

I thought I just saw this question.

In short, no, there's no variable interpolation within an application configuration.

You have two options

1. You could roll your own to substitute variables at runtime
2. At build time, massage the application configuration to the particular specifics of the target deployment environment. Some details on this at dealing with the configuration-nightmare

I had this problem when trying to update my service reference (The error only shows up when adding a service reference though) but didn't want to remove the assembly reuse checkbox.

What worked for me was the following:

• Remove referenced assembly that I wanted to re-use
• Update service reference
• Keep "Reuse types in specified referenced assemblies"
• Ignore the errors, it's because the reference is missing!
• Add reference to assembly again to fix the errors
• Update service reference again

Voila, now it actually updates and doesn't try to remove all of my generated code anymore.

I was almost ready to give up on the re-use types feature...

EDIT: Also make sure that the build config is AnyCPU or x86, since svcutil is buggy with x64.

To the downvoter: Sorry if it didn't work for you, I don't even know why it worked for me, but it did. I may have done something else that time that fixed the problem, but no way to know now.

Try these:

1. window.location.href = 'http://www.google.com';
2. window.location.assign("http://www.w3schools.com");
3. window.location = 'http://www.google.com';

I don't think you need/want the timeout.

onhover (hover) would be defined as the time period while "over" something. IMHO

onmouseover = start...

onmouseout = ...end

For the record I've done some stuff with this to "fake" the hover event in IE6. It was rather expensive and in the end I ditched it in favor of performance.

IF you are using MyEclipse and want to add args before run the program, Then do as follows: 1.0) Run -> Run Config 2.1) Click "Arguments" on the right panel 2.2)add your args in the "Program Args" box, separated by blank

You can call QCoreApplication::exit(0) to exit with code 0

file Protocol
Opens a file on a local or network drive.

Syntax

Copy
 file:///sDrives[|sFile]
Tokens 

sDrives
Specifies the local or network drive.

sFile
Optional. Specifies the file to open. If sFile is omitted and the account accessing the drive has permission to browse the directory, a list of accessible files and directories is displayed.

Remarks

The file protocol and sDrives parameter can be omitted and substituted with just the command line representation of the drive letter and file location. For example, to browse the My Documents directory, the file protocol can be specified as file:///C|/My Documents/ or as C:\My Documents. In addition, a single '\' is equivalent to specifying the root directory on the primary local drive. On most computers, this is C:.

Available as of Microsoft Internet Explorer 3.0 or later.

Note Internet Explorer 6 Service Pack 1 (SP1) no longer allows browsing a local machine from the Internet zone. For instance, if an Internet site contains a link to a local file, Internet Explorer 6 SP1 displays a blank page when a user clicks on the link. Previous versions of Windows Internet Explorer followed the link to the local file.

Example

The following sample demonstrates four ways to use the File protocol.

Copy

//Specifying a drive and a file name. 

file:///C|/My Documents/ALetter.html

//Specifying only a drive and a path to browse the directory. 

file:///C|/My Documents/

//Specifying a drive and a directory using the command line representation of the directory location. 

C:\My Documents\

//Specifying only the directory on the local primary drive. 

\My Documents\

This code worked for me

public static void main(String[] args) {
    try {
        java.net.URL myUr = new java.net.URL("http://path");
        System.out.println("Instantiated new URL: " + connection_url);
    }
    catch (MalformedURLException e) {
        e.printStackTrace();
    }
}

Instantiated new URL: http://path

There is now a an approach to do this, using Doctrine's Criteria.

A full example can be seen in How to use a findBy method with comparative criteria, but a brief answer follows.

use \Doctrine\Common\Collections\Criteria;

// Add a not equals parameter to your criteria
$criteria = new Criteria();
$criteria->where(Criteria::expr()->neq('prize', 200));

// Find all from the repository matching your criteria
$result = $entityRepository->matching($criteria);

This error was showing up in the logs sometimes when I was using a buggy/crashy Cordova iOS version. It went away when I upgraded or downgraded cordova iOS.

The server I was connecting to was using TLSv1.2 SSL so I knew that was not the problem.

=if([Logical Test 1],[Action 1],if([Logical Test 2],[Action 1],if([Logical Test 3],[Action 3],[Value if all logical tests return false])))

Replace the components in the square brackets as necessary.

C# has a lot of reference types. Even if a container stores the references contiguously, the objects themselves may be scattered through the heap

Set the default password in the .pgpass file. If the server does not save the password, it is because it is not set in the .pgpass file, or the permissions are open and the file is therefore ignored.

Read more about the password file here.

Also, be sure to check the permissions: on *nix systems the permissions on .pgpass must disallow any access to world or group; achieve this by the command chmod 0600 ~/.pgpass. If the permissions are less strict than this, the file will be ignored.

Have you tried logging-in using PGAdmin? You can save the password there, and modify the pgpass file.

From Laravel 5.5 on you can use an artisan command to create a new Rule which you can code regarding your requirements to decide whether it passes or fail.

Ej: php artisan make:rule PhoneNumber

Then edit app/Rules/PhoneNumber.php, on method passes

/**
 * Determine if the validation rule passes.
 *
 * @param  string  $attribute
 * @param  mixed  $value
 * @return bool
 */
public function passes($attribute, $value)
{

    return preg_match('%^(?:(?:\(?(?:00|\+)([1-4]\d\d|[1-9]\d?)\)?)?[\-\.\ \\\/]?)?((?:\(?\d{1,}\)?[\-\.\ \\\/]?){0,})(?:[\-\.\ \\\/]?(?:#|ext\.?|extension|x)[\-\.\ \\\/]?(\d+))?$%i', $value) && strlen($value) >= 10;
}

Then, use this Rule as you usually would do with the validation:

use App\Rules\PhoneNumber;

$request->validate([
    'name' => ['required', new PhoneNumber],
]);

docs

There is a JDK socket tutorial here, which covers both the server and client end. That looks exactly like what you want.

(from that tutorial) This sets up to read from an echo server:

    echoSocket = new Socket("taranis", 7);
    out = new PrintWriter(echoSocket.getOutputStream(), true);
    in = new BufferedReader(new InputStreamReader(
                                echoSocket.getInputStream()));

taking a stream of bytes and converts to strings via the reader and using a default encoding (not advisable, normally).

Error handling and closing sockets/streams omitted from the above, but check the tutorial.

What do you consider "special" characters, just simple punctuation? You should be able to use the Replace function: Replace("p.k","."," ").

Sub Test()
Dim myString as String
Dim newString as String

myString = "p.k"

newString = replace(myString, ".", " ")

MsgBox newString

End Sub

If you have several characters, you can do this in a custom function or a simple chained series of Replace functions, etc.

  Sub Test()
Dim myString as String
Dim newString as String

myString = "!p.k"

newString = Replace(Replace(myString, ".", " "), "!", " ")

'## OR, if it is easier for you to interpret, you can do two sequential statements:
'newString = replace(myString, ".", " ")
'newString = replace(newString, "!", " ")

MsgBox newString

End Sub

If you have a lot of potential special characters (non-English accented ascii for example?) you can do a custom function or iteration over an array.

Const SpecialCharacters As String = "!,@,#,$,%,^,&,*,(,),{,[,],},?"  'modify as needed
Sub test()
Dim myString as String
Dim newString as String
Dim char as Variant
myString = "!p#*@)k{kdfhouef3829J"
newString = myString
For each char in Split(SpecialCharacters, ",")
    newString = Replace(newString, char, " ")
Next
End Sub

A little bit late to the party... but I found this as a solution for me when having "blocked"-Error in chrome:

Blocking resources whose URLs contain both \n and < characters.

There was a bug in iOS 6, that causes line height to be ignored when font is set. See answer to NSParagraphStyle line spacing ignored and longer bug analysis at Radar: UITextView Ignores Minimum/Maximum Line Height in Attributed String.

The most reliable way is with

String cleanedString = StringEscapeUtils.unescapeHtml4(originalString);

from org.apache.commons.lang3.StringEscapeUtils.

And to escape the whitespaces

cleanedString = cleanedString.trim();

This will ensure that whitespaces due to copy and paste in web forms to not get persisted in DB.

EJS seems to behave differently depending on whether you use { } notation or not:

I have checked and the following condition is evaluated as you would expect:

<%if (3==3) {%>  TEXT PRINTED  <%}%>
<%if (3==4) {%>  TEXT NOT PRINTED  <%}%>

while this one doesn't:

<%if (3==3) %>  TEXT PRINTED  <% %>
<%if (3==4) %>  TEXT PRINTED  <% %>  

Does your cacerts.pem file hold a single certificate? Since it is a PEM, have a look at it (with a text editor), it should start with

-----BEGIN CERTIFICATE-----

and end with

-----END CERTIFICATE-----

Finally, to check it is not corrupted, get hold of openssl and print its details using

openssl x509 -in cacerts.pem -text

From my understanding matplotlib is a plotting library.

If you want to change the image data (e.g. draw a rectangle on an image), you could use PIL's ImageDraw, OpenCV, or something similar.

Here is PIL's ImageDraw method to draw a rectangle.

Here is one of OpenCV's methods for drawing a rectangle.

Your question asked about Matplotlib, but probably should have just asked about drawing a rectangle on an image.

Here is another question which addresses what I think you wanted to know: Draw a rectangle and a text in it using PIL

It's undesirable to have to know how to instantiate a widget when you just want to override its placeholder.

    q = forms.CharField(label='search')
    ...
    q.widget.attrs['placeholder'] = "Search"

To handle this kind of situation i.e. handling the exception raised by finally block. You can surround the finally block by try block: Look at the below example in python:

try:
   fh = open("testfile", "w")
   try:
      fh.write("This is my test file for exception handling!!")
   finally:
      print "Going to close the file"
      fh.close()
except IOError:
   print "Error: can\'t find file or read data"

If you control both the HTML and CSS, I'd suggest switching to using ID's on all the divs needed for the rounded corner.

CSS

#d1 {
    background: #CFFEB6 url('tr.gif') no-repeat top right;
}
#d2 {
    background: url('br.gif') no-repeat bottom right;
}
#d3 {
    background: url('bl.gif') no-repeat bottom left;
}
#d4 {
    padding: 10px;
}

HTML

<div id="d1"><div id="d2"><div id="d3"><div id="d4">
    <div class='button'><a href='#'>Test</a></div>
</div></div></div></div>

Perl's $[ (deprecated), this was mentioned in another earlier post about generic perl variables, but it deserves specific mention with better explanation. Changes to $[ are limited to current scope.

With jQuery, I've found that sometimes using val to clear the value of a textbox has no effect, in those situations I've found that using attr does the job

$('#searchField').attr("value", "");

Very simple piece of code to do this

$date - extract(day from $date) + 1

two ways to do this:

1. my_date - extract(day from my_date) + 1

2. '2014/01/21' - extract(day from '2014/01/21') + 1

You can just use the Paths class:

Path path = Paths.get(textPath);

... assuming you want to use the default file system, of course.

Here is the solution for masksToBounds conflict problem, it works for me.

After you set the corderRadius/borderColor/shadow and so on, set masksToBounds as NO:

v.layer.masksToBounds = NO;

If you are using jquery you might want to consider their data method.

I have used something similar to what you are trying in your response but like this:

<script src="http://path.to/widget.js" param_a = "2" param_b = "5" param_c = "4">
</script>

You could also create a function that lets you grab the GET params directly (this is what I frequently use):

function $_GET(q,s) {
    s = s || window.location.search;
    var re = new RegExp('&'+q+'=([^&]*)','i');
    return (s=s.replace(/^\?/,'&').match(re)) ? s=s[1] : s='';
}

// Grab the GET param
var param_a = $_GET('param_a');

In most cases (including this one), return will exit immediately. However, if the return is in a try block with an accompanying finally block, the finally always executes and can "override" the return in the try.

function foo() {
    try {
        for (var i = 0; i < 10; i++) {
            if (i % 3 == 0) {
                return i; // This executes once
            }
        }
    } finally {
        return 42; // But this still executes
    }
}

console.log(foo()); // Prints 42

You're putting Integers in so Python is giving you an integer back:

>>> 10 / 90
0

If if you cast this to a float afterwards the rounding will have already been done, in other words, 0 integer will always become 0 float.

If you use floats on either side of the division then Python will give you the answer you expect.

>>> 10 / 90.0
0.1111111111111111

So in your case:

>>> float(20-10) / (100-10)
0.1111111111111111
>>> (20-10) / float(100-10)
0.1111111111111111

you can use convert function :

Select convert(int,[Column1])

Yes :). Try this:

DECLARE @text AS NVARCHAR(10)

SET @text = '100'
SELECT CASE WHEN ISNUMERIC(@text) = 1 THEN CAST(@text AS INT) ELSE NULL END
-- returns 100

SET @text = 'XXX'
SELECT CASE WHEN ISNUMERIC(@text) = 1 THEN CAST(@text AS INT) ELSE NULL END
-- returns NULL

ISNUMERIC() has a few issues pointed by Fedor Hajdu.

It returns true for strings like $ (is currency), , or . (both are separators), + and -.

I had a project that I didn't want to be a web application I wanted it to be a folder. The answer was to delete the web.config file altogether. It only belongs in the root of an application.

You should use classes to make it more simple, instead of the attribute name, or any other jQuery selector.

Really depends on what you're trying to do. Types are documentation in typescript, so you want to show intention about how this thing is supposed to be used when you're creating the type.

Option 1: If Users might have some but not all of the attributes during their lifetime

Make all attributes optional

type User = {
  attr0?: number
  attr1?: string
}

Option 2: If variables containing Users may begin null

type User = {
...
}
let u1: User = null;

Though, really, here if the point is to declare the User object before it can be known what will be assigned to it, you probably want to do let u1:User without any assignment.

Option 3: What you probably want

Really, the premise of typescript is to make sure that you are conforming to the mental model you outline in types in order to avoid making mistakes. If you want to add things to an object one-by-one, this is a habit that TypeScript is trying to get you not to do.

More likely, you want to make some local variables, then assign to the User-containing variable when it's ready to be a full-on User. That way you'll never be left with a partially-formed User. Those things are gross.

let attr1: number = ...
let attr2: string = ...
let user1: User = {
  attr1: attr1,
  attr2: attr2
}

POSIX 7 on echo

http://pubs.opengroup.org/onlinepubs/9699919799/utilities/echo.html

-e is not defined and backslashes are implementation defined:

If the first operand is -n, or if any of the operands contain a <backslash> character, the results are implementation-defined.

unless you have an optional XSI extension.

So I recommend that you should use printf instead, which is well specified:

format operand shall be used as the format string described in XBD File Format Notation [...]

the File Format Notation:

\n <newline> Move the printing position to the start of the next line.

Also keep in mind that Ubuntu 15.10 and most distros implement echo both as:

• a Bash built-in: help echo
• a standalone executable: which echo

which can lead to some confusion.

I'll share a straight-forward way that worked for me.

[" ".join([str(elem) for elem in tup]) for tup in df.columns.tolist()]
#df = df.reset_index() if needed

Another solution is changing the api level of your project in build.gradle and this will work.

To delete file:

del PATH_TO_FILE

To delete folder with all files in it:

rmdir /s /q PATH_TO_FOLDER

To delete all files from specific folder (not deleting folder itself) is a little bit complicated. del /s *.* cannot delete folders, but removes files from all subfolder. So two commands are needed:

del /q PATH_TO_FOLDER\*.*
for /d %i in (PATH_TO_FOLDER\*.*) do @rmdir /s /q "%i"

You can create a script to delete whatever you want (folder or file) like this mydel.bat:

@echo off
setlocal enableextensions

if "%~1"=="" (
    echo Usage: %0 path
    exit /b 1
)

:: check whether it is folder or file
set ISDIR=0
set ATTR=%~a1
set DIRATTR=%ATTR:~0,1%
if /i "%DIRATTR%"=="d" set ISDIR=1

:: Delete folder or file
if %ISDIR%==1 (rmdir /s /q "%~1") else (del "%~1")
exit /b %ERRORLEVEL%

Few example of usage:

mydel.bat "path\to\folder with spaces"
mydel.bat path\to\file_or_folder

Worth mentioning that since version 1.4, Java had the classes java.beans.XMLEncoder and java.beans.XMLDecoder. These classes perform XML encoding which is at least very comparable to XML Serialization and in some circumstances might do the trick for you.

If your class sticks to the JavaBeans specification for its getters and setters, this method is straightforward to use and you don't need a schema. With the following caveats:

• As with normal Java serialization
  • coding and decoding run over a InputStream and OutputStream
  • the process uses the familar writeObject and readObject methods
• In contrast to normal Java serialization
  • the encoding but also decoding causes constructors and initializers to be invoked
  • encoding and decoding work regardless if your class implements Serializable or not
  • transient modifiers are not taken into account
  • works only for public classes, that have public constructors

For example, take the following declaration:

public class NPair {
  public NPair() { }
  int number1 = 0;
  int number2 = 0;
  public void setNumber1(int value) { number1 = value;}
  public int getNumber1() { return number1; }
  public void setNumber2(int value) { number2 = value; }
  public int getNumber2() {return number2;}
}

Executing this code:

NPair fe = new NPair();
fe.setNumber1(12);
fe.setNumber2(13);
FileOutputStream fos1 = new FileOutputStream("d:\\ser.xml");
java.beans.XMLEncoder xe1 = new java.beans.XMLEncoder(fos1);
xe1.writeObject(fe);
xe1.close();

Would result in the following file:

<?xml version="1.0" encoding="UTF-8"?>
<java version="1.7.0_02" class="java.beans.XMLDecoder">
 <object class="NPair">
  <void property="number1">
   <int>12</int>
  </void>
  <void property="number2">
   <int>13</int>
  </void>
 </object>
</java>

What about invoke-item script.bat.

MVC is a controlled environment and MVVM is a reactive environment.

In a controlled environment you should have less code and a common source of logic; which should always live within the controller. However; in the web world MVC easily gets divided into view creation logic and view dynamic logic. Creation lives on the server and dynamic lives on the client. You see this a lot with ASP.NET MVC combined with AngularJS whereas the server will create a View and pass in a Model and send it to the client. The client will then interact with the View in which case AngularJS steps in to as a local controller. Once submitted the Model or a new Model is passed back to the server controller and handled. (Thus the cycle continues and there are a lot of other translations of this handling when working with sockets or AJAX etc but over all the architecture is identical.)

MVVM is a reactive environment meaning you typically write code (such as triggers) that will activate based on some event. In XAML, where MVVM thrives, this is all easily done with the built in databinding framework BUT as mentioned this will work on any system in any View with any programming language. It is not MS specific. The ViewModel fires (usually a property changed event) and the View reacts to it based on whatever triggers you create. This can get technical but the bottom line is the View is stateless and without logic. It simply changes state based on values. Furthermore, ViewModels are stateless with very little logic, and Models are the State with essentially Zero logic as they should only maintain state. I describe this as application state (Model), state translator (ViewModel), and then the visual state / interaction (View).

In an MVC desktop or client side application you should have a Model, and the Model should be used by the Controller. Based on the Model the controller will modify the View. Views are usually tied to Controllers with Interfaces so that the Controller can work with a variety of Views. In ASP.NET the logic for MVC is slightly backwards on the server as the Controller manages the Models and passes the Models to a selected View. The View is then filled with data based on the model and has it's own logic (usually another MVC set such as done with AngularJS). People will argue and get this confused with application MVC and try to do both at which point maintaining the project will eventually become a disaster. ALWAYS put the logic and control in one location when using MVC. DO NOT write View logic in the code behind of the View (or in the View via JS for web) to accommodate Controller or Model data. Let the Controller change the View. The ONLY logic that should live in a View is whatever it takes to create and run via the Interface it's using. An example of this is submitting a username and password. Whether desktop or web page (on client) the Controller should handle the submit process whenever the View fires the Submit action. If done correctly you can always find your way around an MVC web or local app easily.

MVVM is personally my favorite as it's completely reactive. If a Model changes state the ViewModel listens and translates that state and that's it!!! The View is then listening to the ViewModel for state change and it also updates based on the translation from the ViewModel. Some people call it pure MVVM but there's really only one and I don't care how you argue it and it's always Pure MVVM where the View contains absolutely no logic.

Here's a slight example: Let's say the you want to have a menu slide in on a button press. In MVC you will have a MenuPressed action in your interface. The Controller will know when you click the Menu button and then tell the View to slide in the Menu based on another Interface method such as SlideMenuIn. A round trip for what reason? Incase the Controller decides you can't or wants to do something else instead that's why. The Controller should be in charge of the View with the View doing nothing unless the Controller says so. HOWEVER; in MVVM the slide menu in animation should be built in and generic and instead of being told to slide it in will do so based on some value. So it listens to the ViewModel and when the ViewModel says, IsMenuActive = true (or however) the animation for that takes place. Now, with that said I want to make another point REALLY CLEAR and PLEASE pay attention. IsMenuActive is probably BAD MVVM or ViewModel design. When designing a ViewModel you should never assume a View will have any features at all and just pass translated model state. That way if you decide to change your View to remove the Menu and just show the data / options another way, the ViewModel doesn't care. So how would you manage the Menu? When the data makes sense that's how. So, one way to do this is to give the Menu a list of options (probably an array of inner ViewModels). If that list has data, the Menu then knows to open via the trigger, if not then it knows to hide via the trigger. You simply have data for the menu or not in the ViewModel. DO NOT decide to show / hide that data in the ViewModel.. simply translate the state of the Model. This way the View is completely reactive and generic and can be used in many different situations.

All of this probably makes absolutely no sense if you're not already at least slightly familiar with the architecture of each and learning it can be very confusing as you'll find ALOT OF BAD information on the net.

So... things to keep in mind to get this right. Decide up front how to design your application and STICK TO IT.

If you do MVC, which is great, then make sure you Controller is manageable and in full control of your View. If you have a large View consider adding controls to the View that have different Controllers. JUST DON'T cascade those controllers to different controllers. Very frustrating to maintain. Take a moment and design things separately in a way that will work as separate components... And always let the Controller tell the Model to commit or persist storage. The ideal dependency setup for MVC in is View ? Controller ? Model or with ASP.NET (don't get me started) Model ? View ? Controller ? Model (where Model can be the same or a totally different Model from Controller to View) ...of course the only need to know of Controller in View at this point is mostly for endpoint reference to know where back to pass a Model.

If you do MVVM, I bless your kind soul, but take the time to do it RIGHT! Do not use interfaces for one. Let your View decide how it's going to look based on values. Play with the View with Mock data. If you end up having a View that is showing you a Menu (as per the example) even though you didn't want it at the time then GOOD. You're view is working as it should and reacting based on the values as it should. Just add a few more requirements to your trigger to make sure this doesn't happen when the ViewModel is in a particular translated state or command the ViewModel to empty this state. In your ViewModel DO NOT remove this with internal logic either as if you're deciding from there whether or not the View should see it. Remember you can't assume there is a menu or not in the ViewModel. And finally, the Model should just allow you to change and most likely store state. This is where validation and all will occur; for example, if the Model can't modify the state then it will simply flag itself as dirty or something. When the ViewModel realizes this it will translate what's dirty, and the View will then realize this and show some information via another trigger. All data in the View can be binded to the ViewModel so everything can be dynamic only the Model and ViewModel has absolutely no idea about how the View will react to the binding. As a matter of fact the Model has no idea of a ViewModel either. When setting up dependencies they should point like so and only like so View ? ViewModel ? Model (and a side note here... and this will probably get argued as well but I don't care... DO NOT PASS THE MODEL to the VIEW unless that MODEL is immutable; otherwise wrap it with a proper ViewModel. The View should not see a model period. I give a rats crack what demo you've seen or how you've done it, that's wrong.)

Here's my final tip... Look at a well designed, yet very simple, MVC application and do the same for an MVVM application. One will have more control with limited to zero flexibility while the other will have no control and unlimited flexibility.

A controlled environment is good for managing the entire application from a set of controllers or (a single source) while a reactive environment can be broken up into separate repositories with absolutely no idea of what the rest of the application is doing. Micro managing vs free management.

If I haven't confused you enough try contacting me... I don't mind going over this in full detail with illustration and examples.

At the end of the day we're all programmers and with that anarchy lives within us when coding... So rules will be broken, theories will change, and all of this will end up hog wash... But when working on large projects and on large teams, it really helps to agree on a design pattern and enforce it. One day it will make the small extra steps taken in the beginning become leaps and bounds of savings later.

This worked for me :

  e.Row.Cells["cell no "].HorizontalAlign = HorizontalAlign.Center;

But 'css text-align = center ' didn't worked for me

hope it will help you

The && function is not vectorized. You need the & function:

EUR <- PCs[which(PCs$V13 < 9 & PCs$V13 > 3), ]

According to this answer, here is what it says:

In Javascript, you can manipulate DOM CSS properties, for example:

document.getElementById('textboxid').style.height="200px";
document.getElementById('textboxid').style.fontSize="14pt";

If you simply want to specify the height and font size, use CSS or style attributes, e.g.

//in your CSS file or <style> tag
#textboxid
{
    height:200px;
    font-size:14pt;
}

<!--in your HTML-->
<input id="textboxid" ...>

Or

<input style="height:200px;font-size:14pt;" .....>

If you are trying to delete certain .extensions in the C: drive use this cmd:

del /s c:\*.blaawbg

I had a customer that got a encryption virus and i needed to find all junk files and delete them.

As per Nawfal's answer, IF statements need to be in a procedure. I found this post that shows a brilliant example of using your script in a procedure while still developing and testing. Basically, you create, call then drop the procedure:

https://gist.github.com/jeremyjarrell/6083251

You can use .loc to select the specific columns with all rows and then pull that. An example is below:

pandas.merge(dataframe1, dataframe2.iloc[:, [0:5]], how='left', on='key')

In this example, you are merging dataframe1 and dataframe2. You have chosen to do an outer left join on 'key'. However, for dataframe2 you have specified .iloc which allows you to specific the rows and columns you want in a numerical format. Using :, your selecting all rows, but [0:5] selects the first 5 columns. You could use .loc to specify by name, but if your dealing with long column names, then .iloc may be better.

Unfortunately, git branch -a and git branch -r do not show you all remote branches, if you haven't executed a "git fetch".

git remote show origin works consistently all the time. Also git show-ref shows all references in the Git repository. However, it works just like the git branch command.

The answers above work, but keep in mind that if you are opening up in the .xls format, columns ~~might~~ be separated by '\t' instead of ',', the answer https://stackoverflow.com/a/14966131/6169225 worked well for me, so long as I used .join('\t') on the arrays instead of .join(',').

You can also use ADO to do this: http://weblogs.asp.net/fmarguerie/archive/2003/10/01/29964.aspx

Take a look here! It is a native solution written in php. You won't need to exec mysqldump, or cope with incomplete scripts. This is a full mysqldump clone, without dependencies, output compression and sane defaults.

Out of the box, mysqldump-php supports backing up table structures, the data itself, views, triggers and events.

MySQLDump-PHP is the only library that supports:

• output binary blobs as hex.
• resolves view dependencies (using Stand-In tables).
• output compared against original mysqldump. Linked to travis-ci testing system (testing from php 5.3 to 7.1 & hhvm)
• dumps stored procedures.
• dumps events.
• does extended-insert and/or complete-insert.
• supports virtual columns from MySQL 5.7.

You can install it using composer, or just download the php file, and it is as easy as doing:

use Ifsnop\Mysqldump as IMysqldump;

try {
    $dump = new IMysqldump\Mysqldump('database', 'username', 'password');
    $dump->start('storage/work/dump.sql');
} catch (\Exception $e) {
    echo 'mysqldump-php error: ' . $e->getMessage();
}

All the options are explained at the github page, but more or less are auto-explicative:

$dumpSettingsDefault = array(
    'include-tables' => array(),
    'exclude-tables' => array(),
    'compress' => Mysqldump::NONE,
    'init_commands' => array(),
    'no-data' => array(),
    'reset-auto-increment' => false,
    'add-drop-database' => false,
    'add-drop-table' => false,
    'add-drop-trigger' => true,
    'add-locks' => true,
    'complete-insert' => false,
    'databases' => false,
    'default-character-set' => Mysqldump::UTF8,
    'disable-keys' => true,
    'extended-insert' => true,
    'events' => false,
    'hex-blob' => true, /* faster than escaped content */
    'net_buffer_length' => self::MAXLINESIZE,
    'no-autocommit' => true,
    'no-create-info' => false,
    'lock-tables' => true,
    'routines' => false,
    'single-transaction' => true,
    'skip-triggers' => false,
    'skip-tz-utc' => false,
    'skip-comments' => false,
    'skip-dump-date' => false,
    'skip-definer' => false,
    'where' => '',
    /* deprecated */
    'disable-foreign-keys-check' => true
);

Try CSS:

<h2 style="color:#069">Process Report</h2>

If you have more than one h2 tags which should have the same color add a style tag to the head tag like this:

<style type="text/css">
h2 {
    color:#069;
}
</style>

Pretty old question... but I had the same problem today and solved with script, a little bit slow and complex but worked. I did this:

Let's start from the source DB (SQL 2014) right click on the database you would like to backup -> Generate Scripts -> "Script entire database and all database objet" (or u can select only some table if u want) -> the most important step is in the "Set Scripting Options" tab, here you have to click on "Advanced" and look for the option "Script for Server version" and in my case I could select everything from SQL 2005, also pay attention to the option "Types of data to script" I advice "Schema and data" and also Script Triggers and Script Full-text Indexes (if you need, it's false by default) and finally click ok and next. Should look like this:

Now transfer your generated script into your SQL 2008, open it and last Important Step: You must change mdf and ldf location!!

That's all folks, happy F5!! :D

You can implement your OTF font using @font-face like:

@font-face {
    font-family: GraublauWeb;
    src: url("path/GraublauWeb.otf") format("opentype");
}

@font-face {
    font-family: GraublauWeb;
    font-weight: bold;
    src: url("path/GraublauWebBold.otf") format("opentype");
}

// Edit: OTF now works in most browsers, see comments

However if you want to support a wide variety of browsers i would recommend you to switch to WOFF and TTF font types. WOFF type is implemented by every major desktop browser, while the TTF type is a fallback for older Safari, Android and iOS browsers. If your font is a free font, you could convert your font using for example a transfonter.

@font-face {
    font-family: GraublauWeb;
    src: url("path/GraublauWebBold.woff") format("woff"), url("path/GraublauWebBold.ttf")  format("truetype");
}

If you want to support nearly every browser that is still out there (not necessary anymore IMHO), you should add some more font-types like:

@font-face {
    font-family: GraublauWeb;
    src: url("webfont.eot"); /* IE9 Compat Modes */
    src: url("webfont.eot?#iefix") format("embedded-opentype"), /* IE6-IE8 */
         url("webfont.woff") format("woff"), /* Modern Browsers */
         url("webfont.ttf")  format("truetype"), /* Safari, Android, iOS */
         url("webfont.svg#svgFontName") format("svg"); /* Legacy iOS */
}

You can read more about why all these types are implemented and their hacks here. To get a detailed view of which file-types are supported by which browsers, see:

@font-face Browser Support

EOT Browser Support

WOFF Browser Support

TTF Browser Support

hope this helps

The problem seems to be happening when your target sdk is 28. So after trying out many options finally this worked.

<activity
            android:name=".activities.FilterActivity"
            android:theme="@style/Transparent"
            android:windowSoftInputMode="stateHidden|adjustResize" />

style:-

<style name="Transparent" parent="Theme.AppCompat.Light.NoActionBar">
     <item name="android:windowIsTranslucent">true</item>
     <item name="android:windowBackground">@android:color/transparent</item>
     <item name="android:windowIsFloating">true</item>
     <item name="android:windowContentOverlay">@null</item>
     <item name="android:windowNoTitle">true</item>
     <item name="android:backgroundDimEnabled">false</item>
 </style>

Note:parent="Theme.AppCompat.Light.NoActionBar" is needed for api 28. Previously had something else at api 26. Was working great but started to give problem at 28. Hope it helps someone out here. EDIT: For some only by setting <item name="android:windowIsTranslucent">false</item> and <item name="android:windowIsFloating">false</item> worked.May be depends upon the way you implement the solution works.In my case it worked by setting them to true.

This is the simplest solution:

SELECT quote FROM quotes ORDER BY RAND() 

Although it is not the most efficient. This one is a better solution.

Using @EmbeddableId for the PK entity has solved my issue.

@Entity
@Table(name="SAMPLE")
 public class SampleEntity implements Serializable{
   private static final long serialVersionUID = 1L;

   @EmbeddedId
   SampleEntityPK id;

 }

If you take a look at the result of valeur <= 0.6, you can see what’s causing this ambiguity:

>>> valeur <= 0.6
array([ True, False, False, False], dtype=bool)

So the result is another array that has in this case 4 boolean values. Now what should the result be? Should the condition be true when one value is true? Should the condition be true only when all values are true?

That’s exactly what numpy.any and numpy.all do. The former requires at least one true value, the latter requires that all values are true:

>>> np.any(valeur <= 0.6)
True
>>> np.all(valeur <= 0.6)
False

#include <iostream>
#include <sys/time.h>

using namespace std;

int main ()
{
  unsigned long int sec= time(NULL);
  cout<<sec<<endl;
}

No it doesn't need to be constant, the reason why his code above is wrong is because he needs to include a variable name before the declaration.

int row = 8;
int col= 8;
int x[row][col];

In Xcode that will compile and run without any issues, in M$ C++ compiler in .NET it won't compile, it will complain that you cannot use a non const literal to initialize array, the size needs to be known at compile time

Your syntax error is caused by a missing "table" in the query

ALTER TABLE mytable MODIFY mycolumn varchar(255) null;

If every input asks the same question, you should use a for loop and an array of inputs:

Scanner dd = new Scanner(System.in);
int[] vars = new int[3];

for(int i = 0; i < vars.length; i++) {
  System.out.println("Enter next var: ");
  vars[i] = dd.nextInt();
}

Or as Chip suggested, you can parse the input from one line:

Scanner in = new Scanner(System.in);
int[] vars = new int[3];

System.out.println("Enter "+vars.length+" vars: ");
for(int i = 0; i < vars.length; i++)
  vars[i] = in.nextInt();

You were on the right track, and what you did works. This is just a nicer and more flexible way of doing things.

Run package declaration and body separately.

java.util.Date constructor with parameters like new Date(int year, int month, int date, int hrs, int min). is deprecated and preferably do not use it any more. Oracle docs prefers the way over java.util.Calendar. So you can set any date and instantiate Date object through the getTime() method.

Calendar calendar = Calendar.getInstance();
calendar.set(2018, 11, 31, 59, 59, 59);
Date happyNewYearDate = calendar.getTime();

Notice that month number starts from 0

You need to run pip install in the command prompt, outside from a python interpreter ! Try to exit python and re try :)

This can be done with a CSS hack (see the other answers), but it can also be done very easily with JavaScript.

Set the div's width to (for example) 50%, use JavaScript to check its width, and then set the height accordingly. Here's a code example using jQuery:

$(function() {_x000D_
    var div = $('#dynamicheight');_x000D_
    var width = div.width();_x000D_
    _x000D_
    div.css('height', width);_x000D_
});

#dynamicheight_x000D_
{_x000D_
    width: 50%;_x000D_
    _x000D_
    /* Just for looks: */_x000D_
    background-color: cornflowerblue;_x000D_
    margin: 25px;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
_x000D_
<div id="dynamicheight"></div>

If you want the box to scale with the browser window on resize, move the code to a function and call it on the window resize event. Here's a demonstration of that too (view example full screen and resize browser window):

$(window).ready(updateHeight);_x000D_
$(window).resize(updateHeight);_x000D_
_x000D_
function updateHeight()_x000D_
{_x000D_
    var div = $('#dynamicheight');_x000D_
    var width = div.width();_x000D_
    _x000D_
    div.css('height', width);_x000D_
}

#dynamicheight_x000D_
{_x000D_
    width: 50%;_x000D_
    _x000D_
    /* Just for looks: */_x000D_
    background-color: cornflowerblue;_x000D_
    margin: 25px;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
_x000D_
<div id="dynamicheight"></div>

Null comparison is MUCH faster than throwing and catching exception. Exceptions have significant overhead - stack trace must be assembled etc.

Exceptions should represent an unexpected state, which often doesn't represent the situation (which is when as works better).

Add two bindings to your website, one for local access and another for LAN access like so:

Open IIS and select your local website (that you want to access from your local network) from the left panel:

Connections > server (user-pc) > sites > local site

Open Bindings on the right panel under Actions tab add these bindings:

1. Local:

   Type: http
   Ip Address: All Unassigned
   Port: 80
   Host name: samplesite.local
   

2. LAN:

   Type: http
   Ip Address: <Network address of the hosting machine ex. 192.168.0.10>
   Port: 80
   Host name: <Leave it blank>
   

Voila, you should be able to access the website from any machine on your local network by using the host's LAN IP address (192.168.0.10 in the above example) as the site url.

NOTE:

if you want to access the website from LAN using a host name (like samplesite.local) instead of an ip address, add the host name to the hosts file on the local network machine (The hosts file can be found in "C:\Windows\System32\drivers\etc\hosts" in windows, or "/etc/hosts" in ubuntu):

192.168.0.10 samplesite.local

You can use pub_image context (holder.pub_image.getContext()) :

@Override
public void onBindViewHolder(ViewHolder ViewHolder, int position) {

    holder.txtHeader.setText(mDataset.get(position).getPost_text());

    Picasso.with(holder.pub_image.getContext()).load("http://i.imgur.com/DvpvklR.png").into(holder.pub_image);


}

I've decided to give an answer to this question because I think it can be solved using a simpler syntax than the convoluted try-catch block. The Laravel documentation is pretty brief on this subject.

Instead of using try-catch, you can just use the DB::transaction(){...} wrapper like this:

// MyController.php
public function store(Request $request) {
    return DB::transaction(function() use ($request) {
        $user = User::create([
            'username' => $request->post('username')
        ]);

        // Add some sort of "log" record for the sake of transaction:
        $log = Log::create([
            'message' => 'User Foobar created'
        ]);

        // Lets add some custom validation that will prohibit the transaction:
        if($user->id > 1) {
            throw AnyException('Please rollback this transaction');
        }

        return response()->json(['message' => 'User saved!']);
    });
};

You should then see that the User and the Log record cannot exist without eachother.

Some notes on the implementation above:

• Make sure to return the transaction, so that you can use the response() you return within its callback.
• Make sure to throw an exception if you want the transaction to be rollbacked (or have a nested function that throws the exception for you automatically, like an SQL exception from within Eloquent).
• The id, updated_at, created_at and any other fields are AVAILABLE AFTER CREATION for the $user object (for the duration of this transaction). The transaction will run through any of the creation logic you have. HOWEVER, the whole record is discarded when the AnyException is thrown. This means that for instance an auto-increment column for id does get incremented on failed transactions.

Tested on Laravel 5.8

This should do it:

var newClass = window.location.href;
newClass = newClass.substring(newClass.lastIndexOf('/')+1, 5);
$('body').addClass(newClass);

The whole "five characters" thing is a little worrisome; that kind of arbitrary cutoff is usually a red flag. I'd recommend catching everything until an _ or .:

newClass = newClass.match(/\/[^\/]+(_|\.)[^\/]+$/);

That pattern should yield the following:

• ../about_us.html : about
• ../something.html : something
• ../has_two_underscores.html : has

In general, this depends what your map contains. If it has null values, things can get tricky and containsKey(key) or get(key, default) should be used to detect of the element really exists. In many cases the code can become simpler you can define a default value:

def mymap = [name:"Gromit", likes:"cheese", id:1234]
def x1 = mymap.get('likes', '[nothing specified]')
println "x value: ${x}" }

Note also that containsKey() or get() are much faster than setting up a closure to check the element mymap.find{ it.key == "likes" }. Using closure only makes sense if you really do something more complex in there. You could e.g. do this:

mymap.find{ // "it" is the default parameter
  if (it.key != "likes") return false
  println "x value: ${it.value}" 
  return true // stop searching
}

Or with explicit parameters:

mymap.find{ key,value ->
  (key != "likes")  return false
  println "x value: ${value}" 
  return true // stop searching
}

Method 1 :

var stringValue = "true";
var boolValue = (/true/i).test(stringValue) //returns true

Method 2 :

var stringValue = "true";
var boolValue = (stringValue =="true");   //returns true

Method 3 :

var stringValue = "true";
var boolValue = JSON.parse(stringValue);   //returns true

Method 4 :

var stringValue = "true";
var boolValue = stringValue.toLowerCase() == 'true'; //returns true

Method 5 :

var stringValue = "true";
var boolValue = getBoolean(stringValue); //returns true
function getBoolean(value){
   switch(value){
        case true:
        case "true":
        case 1:
        case "1":
        case "on":
        case "yes":
            return true;
        default: 
            return false;
    }
}

If you're only appending a single variable, then push() works just fine. If you need to append another array, use concat():

var ar1 = [1, 2, 3];_x000D_
var ar2 = [4, 5, 6];_x000D_
_x000D_
var ar3 = ar1.concat(ar2);_x000D_
_x000D_
alert(ar1);_x000D_
alert(ar2);_x000D_
alert(ar3);

The concat does not affect ar1 and ar2 unless reassigned, for example:

var ar1 = [1, 2, 3];_x000D_
var ar2 = [4, 5, 6];_x000D_
_x000D_
ar1 = ar1.concat(ar2);_x000D_
alert(ar1);

Lots of great info here.

In Java (or other languages), using Property/Attribute depends on usage:

• Property used when value doesn't change very often (usually used at startup or for environment variable)

• Attributes is a value (object child) of an Element (object) which can change very often/all the time and be or not persistent

The top answer worked fine but I suggest saving your JSON data into a variable before posting it is a little bit cleaner when sending a long form or dealing with large data in general.

var Data = {_x000D_
"name":"jonsa",_x000D_
"e-mail":"[email protected]",_x000D_
"phone":1223456789_x000D_
};_x000D_
_x000D_
_x000D_
$.ajax({_x000D_
    type: 'POST',_x000D_
    url: '/form/',_x000D_
    data: Data,_x000D_
    success: function(data) { alert('data: ' + data); },_x000D_
    contentType: "application/json",_x000D_
    dataType: 'json'_x000D_
});

I tried all of those above answers, and I then summarized a pipeline of how to draw the fixed-axes image. It applied both to show function and savefig function.

1. before you plot:

   fig = pylab.figure()
   ax = fig.gca()
   ax.set_autoscale_on(False)
   

This is to request an ax which is subplot(1,1,1).

2. During the plot:

   ax.plot('You plot argument') # Put inside your argument, like ax.plot(x,y,label='test')
   ax.axis('The list of range') # Put in side your range [xmin,xmax,ymin,ymax], like ax.axis([-5,5,-5,200])
   

3. After the plot:

   1. To show the image :

      fig.show()
      

   2. To save the figure :

      fig.savefig('the name of your figure')
      

I find out that put axis at the front of the code won't work even though I have set autoscale_on to False.

I used this code to create a series of animation. And below is the example of combing multiple fixed axes images into an animation.

[[NSUserDefaults standardUserDefaults] setValue:aString forKey:aKey]

Here's one solution:

df.expanded <- df[rep(row.names(df), df$freq), 1:2]

Result:

    var1 var2
1      a    d
2      b    e
2.1    b    e
3      c    f
3.1    c    f
3.2    c    f

I choose use javascript:void(0), because use this could prevent right click to open the content menu. But javascript:; is shorter and does the same thing.

I found that just using the connectivity package was not enough to tell if the internet was available or not. In Android it only checks if there is WIFI or if mobile data is turned on, it does not check for an actual internet connection . During my testing, even with no mobile signal ConnectivityResult.mobile would return true.

With IOS my testing found that the connectivity plugin does correctly detect if there is an internet connection when the phone has no signal, the issue was only with Android.

The solution I found was to use the data_connection_checker package along with the connectivity package. This just makes sure there is an internet connection by making requests to a few reliable addresses, the default timeout for the check is around 10 seconds.

My finished isInternet function looked a bit like this:

  Future<bool> isInternet() async {
    var connectivityResult = await (Connectivity().checkConnectivity());
    if (connectivityResult == ConnectivityResult.mobile) {
      // I am connected to a mobile network, make sure there is actually a net connection.
      if (await DataConnectionChecker().hasConnection) {
        // Mobile data detected & internet connection confirmed.
        return true;
      } else {
        // Mobile data detected but no internet connection found.
        return false;
      }
    } else if (connectivityResult == ConnectivityResult.wifi) {
      // I am connected to a WIFI network, make sure there is actually a net connection.
      if (await DataConnectionChecker().hasConnection) {
        // Wifi detected & internet connection confirmed.
        return true;
      } else {
        // Wifi detected but no internet connection found.
        return false;
      }
    } else {
      // Neither mobile data or WIFI detected, not internet connection found.
      return false;
    }
  }

The if (await DataConnectionChecker().hasConnection) part is the same for both mobile and wifi connections and should probably be moved to a separate function. I've not done that here to leave it more readable.

This is my first Stack Overflow answer, hope it helps someone.

Mac (French-Canadian Keyboard):

"É" is on the same position as "?/" in english one.

This is an error that is some how had to debug. As it has been said many times, improper import/export can cause this error but surprisingly i got this error from a small bug in my react-router-dom authentication setup below is my case:

WRONG SETUP:

const PrivateRoute = ({ component: Component, ...rest }) => (
    <Route
        {...rest}
        render={(props) => (token ? <Component {...props} /> : <Redirect to={{ pathname: "/login" }} />)}
    />
);

CORRECT SETUP:

const PrivateRoute = ({ component: Component, token, ...rest }) => (
    <Route
        {...rest}
        render={(props) => (token ? <Component {...props} /> : <Redirect to={{ pathname: "/login" }} />)}
    />
);

The only difference was I was deconstructing the token in the PrivateRoute component. By the way the token is gotten from localstorage like this const token = localStorage.getItem("authUser"); so if it is not there I know the user is not authenticated. This can also cause that error.

It's very simple. Just try:

start chrome https://www.google.co.in/

it will open the Google page in the Chrome browser.

If you wish to open the page in Firefox, try:

get current date and time

var now = new Date(); 
  var datetime = now.getFullYear()+'/'+(now.getMonth()+1)+'/'+now.getDate(); 
  datetime += ' '+now.getHours()+':'+now.getMinutes()+':'+now.getSeconds(); 

It's because your '/new_sandbox/' begins with a / and thus is assumed to be relative to the root directory. Remove the leading /.

I encountered this error when using Travis CI to deploy content, which involved pushing edits to a repository.

I eventually solved the issue by updating the GitHub personal access token associated with the Travis account with the public_repo scope access permission:

It is possible. But you have to hack it a little, there is a code What you have to do is to run stand alone server and "patch" RemoteWebDriver

public class CustomRemoteWebDriver : RemoteWebDriver
{
    public static bool newSession;
    public static string capPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "TestFiles", "tmp", "sessionCap");
    public static string sessiodIdPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "TestFiles", "tmp", "sessionid");

    public CustomRemoteWebDriver(Uri remoteAddress) 
        : base(remoteAddress, new DesiredCapabilities())
    {
    }

    protected override Response Execute(DriverCommand driverCommandToExecute, Dictionary<string, object> parameters)
    {
        if (driverCommandToExecute == DriverCommand.NewSession)
        {
            if (!newSession)
            {
                var capText = File.ReadAllText(capPath);
                var sidText = File.ReadAllText(sessiodIdPath);

                var cap = JsonConvert.DeserializeObject<Dictionary<string, object>>(capText);
                return new Response
                {
                    SessionId = sidText,
                    Value = cap
                };
            }
            else
            {
                var response = base.Execute(driverCommandToExecute, parameters);
                var dictionary = (Dictionary<string, object>) response.Value;
                File.WriteAllText(capPath, JsonConvert.SerializeObject(dictionary));
                File.WriteAllText(sessiodIdPath, response.SessionId);
                return response;
            }
        }
        else
        {
            var response = base.Execute(driverCommandToExecute, parameters);
            return response;
        }
    }
}

Your code is way more cluttered than necessary.

Replace (Not (X Is Nothing)) with X IsNot Nothing and omit the outer parentheses:

If comp.Container IsNot Nothing AndAlso comp.Container.Components IsNot Nothing Then
    For i As Integer = 0 To comp.Container.Components.Count() - 1
        fixUIIn(comp.Container.Components(i), style)
    Next
End If

Much more readable. … Also notice that I’ve removed the redundant Step 1 and the probably redundant .Item.

But (as pointed out in the comments), index-based loops are out of vogue anyway. Don’t use them unless you absolutely have to. Use For Each instead:

If comp.Container IsNot Nothing AndAlso comp.Container.Components IsNot Nothing Then
    For Each component In comp.Container.Components
        fixUIIn(component, style)
    Next
End If

Or you can do this without using Delay.

set /a "counter=0"

-> your for loop here

do (
   statement1
   statement2
   call :increaseby1
 )

:increaseby1
set /a "counter+=1"

Try string.TrimEnd():

Something = Something.TrimEnd(',');

I would set the maximum size, minimum size and remove the gripper icon of the window.

Set properties (MaximumSize, MinimumSize, and SizeGripStyle):

this.MaximumSize = new System.Drawing.Size(500, 550);
this.MinimumSize = new System.Drawing.Size(500, 550);
this.SizeGripStyle = System.Windows.Forms.SizeGripStyle.Hide;

$text='<span style="font-weight: bold;">Foo</span>';
$text=preg_replace( '/<span style="font-weight: bold;">(.*?)<\/span>/', '<strong>$1</strong>',$text);

Note: only work for your example.

Check the version of Gradle install in Android Studio and the one mentioned in Build.Grable file

`dependencies { classpath 'com.android.tools.build:gradle:3.1.1'

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}`

I replace 3.1.1 to 3.0.0 and it worked for me, check your own version of Gradle. Or try to create new project and check its build.gradle file to know the installed version.

This is how I understood the difference between them in terms of design patterns:

Service: Return a type, that will be newed to create an object of that type. If Java analogy is used, Service returns a Java Class definition.

Factory: Returns a concrete object that can be immediately used. In Java Analogy a Factory returns a Java Object.

The part that often confuses people (including myself) is that when you inject a Service or a Factory in your code they can be used the same way, what you get in your code in both cases is a concrete object that you can immediately invoke. Which means in case of the Service, angular calls "new" on the service declaration on behalf of you. I think this is a convoluted concept.

You could add in your code a call system with the new definition:

sprintf(newdef,"export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:%s:%s",ld1,ld2);
system(newdef);

But, I don't know it that is the rigth solution but it works.

Thanks to @Jousby's solution, I managed to get mine working as well, but found I had to improve his solution's Bootstrap modal markup a bit to make it render correctly as demonstrated in the official examples.

So, here's my modified version of the generic confirm function that worked fine:

/* Generic Confirm func */
  function confirm(heading, question, cancelButtonTxt, okButtonTxt, callback) {

    var confirmModal = 
      $('<div class="modal fade">' +        
          '<div class="modal-dialog">' +
          '<div class="modal-content">' +
          '<div class="modal-header">' +
            '<a class="close" data-dismiss="modal" >&times;</a>' +
            '<h3>' + heading +'</h3>' +
          '</div>' +

          '<div class="modal-body">' +
            '<p>' + question + '</p>' +
          '</div>' +

          '<div class="modal-footer">' +
            '<a href="#!" class="btn" data-dismiss="modal">' + 
              cancelButtonTxt + 
            '</a>' +
            '<a href="#!" id="okButton" class="btn btn-primary">' + 
              okButtonTxt + 
            '</a>' +
          '</div>' +
          '</div>' +
          '</div>' +
        '</div>');

    confirmModal.find('#okButton').click(function(event) {
      callback();
      confirmModal.modal('hide');
    }); 

    confirmModal.modal('show');    
  };  
/* END Generic Confirm func */

For example:

const std::map<LogLevel, const char*> g_log_levels_dsc =
{
    { LogLevel::Disabled, "[---]" },
    { LogLevel::Info,     "[inf]" },
    { LogLevel::Warning,  "[wrn]" },
    { LogLevel::Error,    "[err]" },
    { LogLevel::Debug,    "[dbg]" }
};

If map is a data member of a class, you can initialize it directly in header by the following way (since C++17):

// Example

template<>
class StringConverter<CacheMode> final
{
public:
    static auto convert(CacheMode mode) -> const std::string&
    {
        // validate...
        return s_modes.at(mode);
    }

private:
    static inline const std::map<CacheMode, std::string> s_modes =
        {
            { CacheMode::All, "All" },
            { CacheMode::Selective, "Selective" },
            { CacheMode::None, "None" }
            // etc
        };
}; 

Another option for Pagination in RESTFul APIs, is to use the Link header introduced here. For example Github use it as follow:

Link: <https://api.github.com/user/repos?page=3&per_page=100>; rel="next",
  <https://api.github.com/user/repos?page=50&per_page=100>; rel="last"

The possible values for rel are: first, last, next, previous. But by using Link header, it may be not possible to specify total_count (total number of elements).

Use dataType: "jsonp". I had the same error before. It fixed for me.

I was encountering the same issue. In my App build.gradle I had

apply plugin: 'com.android.application'
apply plugin: 'dexguard'
apply plugin: 'io.fabric'

I just switched Dexguard and Fabric, then it worked!

apply plugin: 'com.android.application'
apply plugin: 'io.fabric'
apply plugin: 'dexguard'

You can stop a macro by pressing ctrl + break but if you don't have the break key you could use this autohotkey (open source) code:

+ESC:: SendInput {CtrlBreak} return

Pressing shift + Escape will be like pressing ctrl + break and thus will stop your macro.

First of all we will get source and destination points between which we have to draw route. Then we will pass these attribute to below function.

 public String makeURL (double sourcelat, double sourcelog, double destlat, double destlog ){
        StringBuilder urlString = new StringBuilder();
        urlString.append("http://maps.googleapis.com/maps/api/directions/json");
        urlString.append("?origin=");// from
        urlString.append(Double.toString(sourcelat));
        urlString.append(",");
        urlString.append(Double.toString( sourcelog));
        urlString.append("&destination=");// to
        urlString.append(Double.toString( destlat));
        urlString.append(",");
        urlString.append(Double.toString( destlog));
        urlString.append("&sensor=false&mode=driving&alternatives=true");
        urlString.append("&key=YOUR_API_KEY");
        return urlString.toString();
 }

This function will make the url that we will send to get Direction API response. Then we will parse that response . The parser class is

public class JSONParser {

    static InputStream is = null;
    static JSONObject jObj = null;
    static String json = "";
    // constructor
    public JSONParser() {
    }
    public String getJSONFromUrl(String url) {

        // Making HTTP request
        try {
            // defaultHttpClient
            DefaultHttpClient httpClient = new DefaultHttpClient();
            HttpPost httpPost = new HttpPost(url);

            HttpResponse httpResponse = httpClient.execute(httpPost);
            HttpEntity httpEntity = httpResponse.getEntity();
            is = httpEntity.getContent();           

        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        try {
            BufferedReader reader = new BufferedReader(new InputStreamReader(
                    is, "iso-8859-1"), 8);
            StringBuilder sb = new StringBuilder();
            String line = null;
            while ((line = reader.readLine()) != null) {
                sb.append(line + "\n");
            }

            json = sb.toString();
            is.close();
        } catch (Exception e) {
            Log.e("Buffer Error", "Error converting result " + e.toString());
        }
        return json;

    }
}

This parser will return us string. We will call it like that.

JSONParser jParser = new JSONParser();
String json = jParser.getJSONFromUrl(url);

Now we will send this string to our drawpath function. The drawpath function is

public void drawPath(String  result) {

    try {
            //Tranform the string into a json object
           final JSONObject json = new JSONObject(result);
           JSONArray routeArray = json.getJSONArray("routes");
           JSONObject routes = routeArray.getJSONObject(0);
           JSONObject overviewPolylines = routes.getJSONObject("overview_polyline");
           String encodedString = overviewPolylines.getString("points");
           List<LatLng> list = decodePoly(encodedString);
           Polyline line = mMap.addPolyline(new PolylineOptions()
                                    .addAll(list)
                                    .width(12)
                                    .color(Color.parseColor("#05b1fb"))//Google maps blue color
                                    .geodesic(true)
                    );
           /*
           for(int z = 0; z<list.size()-1;z++){
                LatLng src= list.get(z);
                LatLng dest= list.get(z+1);
                Polyline line = mMap.addPolyline(new PolylineOptions()
                .add(new LatLng(src.latitude, src.longitude), new LatLng(dest.latitude,   dest.longitude))
                .width(2)

Above code will draw the path on mMap. The code of decodePoly is

private List<LatLng> decodePoly(String encoded) {

    List<LatLng> poly = new ArrayList<LatLng>();
    int index = 0, len = encoded.length();
    int lat = 0, lng = 0;

    while (index < len) {
        int b, shift = 0, result = 0;
        do {
            b = encoded.charAt(index++) - 63;
            result |= (b & 0x1f) << shift;
            shift += 5;
        } while (b >= 0x20);
        int dlat = ((result & 1) != 0 ? ~(result >> 1) : (result >> 1));
        lat += dlat;

        shift = 0;
        result = 0;
        do {
            b = encoded.charAt(index++) - 63;
            result |= (b & 0x1f) << shift;
            shift += 5;
        } while (b >= 0x20);
        int dlng = ((result & 1) != 0 ? ~(result >> 1) : (result >> 1));
        lng += dlng;

        LatLng p = new LatLng( (((double) lat / 1E5)),
                 (((double) lng / 1E5) ));
        poly.add(p);
    }

    return poly;
}

As direction call may take time so we will do all this in Asynchronous task. My Asynchronous task was

        if(result!=null){
            drawPath(result);
        }
    }

I hope it will help.

Use try block in your code like

try
{
    // Your code...
    // Could also be before try if you know the exception occurs in SaveChanges

    context.SaveChanges();
}
catch (DbEntityValidationException e)
{
    foreach (var eve in e.EntityValidationErrors)
    {
        Console.WriteLine("Entity of type \"{0}\" in state \"{1}\" has the following validation errors:",
            eve.Entry.Entity.GetType().Name, eve.Entry.State);
        foreach (var ve in eve.ValidationErrors)
        {
            Console.WriteLine("- Property: \"{0}\", Error: \"{1}\"",
                ve.PropertyName, ve.ErrorMessage);
        }
    }
    throw;
}

You can check the details here as well

You can use DataTrigger class in Microsoft.Expression.Interactions.dll that come with Expression Blend.

Code Sample:

<i:Interaction.Triggers>
    <i:DataTrigger Binding="{Binding YourProperty}" Value="{x:Null}" Comparison="NotEqual">
       <ie:ChangePropertyAction PropertyName="YourTargetPropertyName" Value="{Binding YourValue}"/>
    </i:DataTrigger
</i:Interaction.Triggers>

Using this method you can trigger against GreaterThan and LessThan too. In order to use this code you should reference two dll's:

System.Windows.Interactivity.dll

Microsoft.Expression.Interactions.dll

In SSMS, "Query" menu item... "Results to"... "Results to File"

Shortcut = CTRL+shift+F

You can set it globally too

"Tools"... "Options"... "Query Results"... "SQL Server".. "Default destination" drop down

Edit: after comment

In SSMS, "Query" menu item... "SQLCMD" mode

This allows you to run "command line" like actions.

A quick test in my SSMS 2008

:OUT c:\foo.txt
SELECT * FROM sys.objects

Edit, Sep 2012

:OUT c:\foo.txt
SET NOCOUNT ON;SELECT * FROM sys.objects

Here is one way to do it. It uses the ability of R to construct file paths based on the platform and hence will work on both Mac OS and Windows. Moreover, you don't need to convert your xls file to csv, as there are many R packages that will help you read xls directly (e.g. gdata package).

# get user's home directory
home = setwd(Sys.getenv("HOME"));

# construct path to file
fpath = file.path(home, "Desktop", "RTrial.xls");

# load gdata library to read xls files
library(gdata);

# read xls file
Rtrial = read.xls(fpath);

Let me know if this works.

I am using this from PowerShell:

dir -directory -name -recurse > list_my_folders.txt

If in Chinses

import codecs
fout = codecs.open("xxx.json", "w", "utf-8")
dict_to_json = json.dumps({'text':"??"},ensure_ascii=False,indent=2)
fout.write(dict_to_json + '\n')

Cover the offending elements with an invisible block, using a pseudo element: :before or :after

a:before {
//IE No click hack by covering the element.
  display:block;
  position:absolute;
  height:100%;
  width:100%;
  content:' ';
}

Thus you're click lands on the parent element. No good, if the parent is clickable, but works well otherwise.

String webviewurl = "http://test.com/testing.pdf";
webView.getSettings().setJavaScriptEnabled(true); 
if(webviewurl.contains(".pdf")){
    webviewurl = "http://docs.google.com/gview?embedded=true&url=" + webviewurl;        }
webview.loadUrl(webviewurl);

Note that "number of cores" might not be a particularly useful number, you might have to qualify it a bit more. How do you want to count multi-threaded CPUs such as Intel HT, IBM Power5 and Power6, and most famously, Sun's Niagara/UltraSparc T1 and T2? Or even more interesting, the MIPS 1004k with its two levels of hardware threading (supervisor AND user-level)... Not to mention what happens when you move into hypervisor-supported systems where the hardware might have tens of CPUs but your particular OS only sees a few.

The best you can hope for is to tell the number of logical processing units that you have in your local OS partition. Forget about seeing the true machine unless you are a hypervisor. The only exception to this rule today is in x86 land, but the end of non-virtual machines is coming fast...

you can use laravel validation if you want to insert a unique record:

$validated = $request->validate([
    'title' => 'required|unique:usersTable,emailAddress|max:255',
]);

But you use these ways also:

1:

if (User::where('email',  $request->email)->exists())
{
  // object exists
} else {
  // object not found
}

2:

$user = User::where('email',  $request->email)->first();

if ($user)
{
  // object exists
} else {
  // object not found
}

3:

$user = User::where('email',  $request->email)->first();

if ($user->isEmpty())
{
  // object exists
} else {
  // object not found
}

4:

$user = User::where('email',  $request->email)->firstOrCreate([
      'email' => 'email'
],$request->all());

The <h:outputLink> renders a fullworthy HTML <a> element with the proper URL in the href attribute which fires a bookmarkable GET request. It cannot directly invoke a managed bean action method.

<h:outputLink value="destination.xhtml">link text</h:outputLink>

The <h:commandLink> renders a HTML <a> element with an onclick script which submits a (hidden) POST form and can invoke a managed bean action method. It's also required to be placed inside a <h:form>.

<h:form>
    <h:commandLink value="link text" action="destination" />
</h:form>

The ?faces-redirect=true parameter on the <h:commandLink>, which triggers a redirect after the POST (as per the Post-Redirect-Get pattern), only improves bookmarkability of the target page when the link is actually clicked (the URL won't be "one behind" anymore), but it doesn't change the href of the <a> element to be a fullworthy URL. It still remains #.

<h:form>
    <h:commandLink value="link text" action="destination?faces-redirect=true" />
</h:form>

Since JSF 2.0, there's also the <h:link> which can take a view ID (a navigation case outcome) instead of an URL. It will generate a HTML <a> element as well with the proper URL in href.

<h:link value="link text" outcome="destination" />

So, if it's for pure and bookmarkable page-to-page navigation like the SO username link, then use <h:outputLink> or <h:link>. That's also better for SEO since bots usually doesn't cipher POST forms nor JS code. Also, UX will be improved as the pages are now bookmarkable and the URL is not "one behind" anymore.

When necessary, you can do the preprocessing job in the constructor or @PostConstruct of a @RequestScoped or @ViewScoped @ManagedBean which is attached to the destination page in question. You can make use of @ManagedProperty or <f:viewParam> to set GET parameters as bean properties.

Here's the shortest solution, based on vh. Please note that vh is not supported in some older browsers.

CSS:

div {
    width: 100%;
    height: 100vh;
}

HTML:

<div>This div is fullscreen :)</div>

I had the same issue, it turned out to be that nuget packages were not automatically downloaded for a solution i downloaded from the repository freshly, thus intellisense was not available since none of the required packages to show the right suggestions were available.

This may be the answer you're looking for:

grep abc MyFile | grep def

Only thing is... it will output lines were "def" is before OR after "abc"

func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool

        {
            let textString = (textField.text! as NSString).replacingCharacters(in: range, with: string)

            if textField == self.phoneTextField  && string.characters.count > 0{
                let numberOnly = NSCharacterSet.decimalDigits
                let strValid = numberOnly.contains(UnicodeScalar.init(string)!)
                return strValid && textString.characters.count <= 10
            }
            return true
        }

in above code is working in swift 3
NSCharacterSet.decimalDigits
You are also use letters only
NSCharacterSet.Letters
and uppercase,Lowercaseand,alphanumerics,whitespaces is used same code or See the Link

Since I do a lot of dynamic queries, this is a super simple helper function I made.

public static function bindParamArray($prefix, $values, &$bindArray)
{
    $str = "";
    foreach($values as $index => $value){
        $str .= ":".$prefix.$index.",";
        $bindArray[$prefix.$index] = $value;
    }
    return rtrim($str,",");     
}

Use it like this:

$bindString = helper::bindParamArray("id", $_GET['ids'], $bindArray);
$userConditions .= " AND users.id IN($bindString)";

Returns a string :id1,:id2,:id3 and also updates your $bindArray of bindings that you will need when it's time to run your query. Easy!

Here is the source of these column flags

Your syntax and logic are incorrect in a number of ways. You need to create an index variable and use it to access the array's elements, like so:

int i = 0;        // Create a separate integer to serve as your array indexer.
while(i < 10) {   // The indexer needs to be less than 10, not A itself.
   sum += A[i];   // either sum = sum + ... or sum += ..., but not both
   i++;           // You need to increment the index at the end of the loop.
}

The above example uses a while loop, since that's the approach you took. A more appropriate construct would be a for loop, as in Bogdan's answer.

     SELECT *  FROM sys.dm_exec_sessions es
  INNER JOIN sys.dm_exec_connections ec
      ON es.session_id = ec.session_id
  CROSS APPLY sys.dm_exec_sql_text(ec.most_recent_sql_handle) where es.session_id=65 under see text contain...

You can use standard s3 api -

aws s3 ls s3://root/folder1/folder2/

You can define one border per side only. You would have to add an extra element for that!

You have a choice, when you create an object array (as opposed to an array of primitives).

One option is to specify a size for the array, in which case it will just contain lots of nulls.

String[] array = new String[10]; // Array of size 10, filled with nulls.

The other option is to specify what will be in the array.

String[] array = new String[] {"Larry", "Curly", "Moe"};  // Array of size 3, filled with stooges.

But you can't mix the two syntaxes. Pick one or the other.

I don't believe that there is a well-supported multi-platform library available. Remember that Python itself is written in C so any library is simply going to make a smart decision about which OS-specific code snippet to run, as you suggested above.

To convert an object to a byte array:

// Convert an object to a byte array
public static byte[] ObjectToByteArray(Object obj)
{
    BinaryFormatter bf = new BinaryFormatter();
    using (var ms = new MemoryStream())
    {
        bf.Serialize(ms, obj);
        return ms.ToArray();
    }
}

You just need copy this function to your code and send to it the object that you need to convert to a byte array. If you need convert the byte array to an object again you can use the function below:

// Convert a byte array to an Object
public static Object ByteArrayToObject(byte[] arrBytes)
{
    using (var memStream = new MemoryStream())
    {
        var binForm = new BinaryFormatter();
        memStream.Write(arrBytes, 0, arrBytes.Length);
        memStream.Seek(0, SeekOrigin.Begin);
        var obj = binForm.Deserialize(memStream);
        return obj;
    }
}

You can use these functions with custom classes. You just need add the [Serializable] attribute in your class to enable serialization

If you are using MS Excel 2007, you could use the conditional formatting on the Home tab as shown in the screenshot below. You could either use the color scales default option as I have done here or you can go ahead and create a new rule based on your data set.

Before messing with Nginx config, try to disable ChromePHP first.

1 - Open app/config/config_dev.yml

2 - Comment these lines:

chromephp:
    type:   chromephp
    level:  info

ChromePHP pack the debug info json-encoded in the X-ChromePhp-Data header, which is too big for the default config of nginx with fastcgi.

I would generally try to avoid the use of #pragmas if possible, since they're extremely compiler-dependent and non-portable. If you want to use them in a portable fashion, you'll have to surround every pragma with a #if/#endif pair. GCC discourages the use of pragmas, and really only supports some of them for compatibility with other compilers; GCC has other ways of doing the same things that other compilers use pragmas for.

For example, here's how you'd ensure that a structure is packed tightly (i.e. no padding between members) in MSVC:

#pragma pack(push, 1)
struct PackedStructure
{
  char a;
  int b;
  short c;
};
#pragma pack(pop)
// sizeof(PackedStructure) == 7

Here's how you'd do the same thing in GCC:

struct PackedStructure __attribute__((__packed__))
{
  char a;
  int b;
  short c;
};
// sizeof(PackedStructure == 7)

The GCC code is more portable, because if you want to compile that with a non-GCC compiler, all you have to do is

#define __attribute__(x)

Whereas if you want to port the MSVC code, you have to surround each pragma with a #if/#endif pair. Not pretty.

logging.basicConfig() can take a keyword argument handlers since Python 3.3, which simplifies logging setup a lot, especially when setting up multiple handlers with the same formatter:

handlers – If specified, this should be an iterable of already created handlers to add to the root logger. Any handlers which don’t already have a formatter set will be assigned the default formatter created in this function.

The whole setup can therefore be done with a single call like this:

import logging

logging.basicConfig(
    level=logging.INFO,
    format="%(asctime)s [%(levelname)s] %(message)s",
    handlers=[
        logging.FileHandler("debug.log"),
        logging.StreamHandler()
    ]
)

(Or with import sys + StreamHandler(sys.stdout) per original question's requirements – the default for StreamHandler is to write to stderr. Look at LogRecord attributes if you want to customize the log format and add things like filename/line, thread info etc.)

The setup above needs to be done only once near the beginning of the script. You can use the logging from all other places in the codebase later like this:

logging.info('Useful message')
logging.error('Something bad happened')
...

Note: If it doesn't work, someone else has probably already initialized the logging system differently. Comments suggest doing logging.root.handlers = [] before the call to basicConfig().

If you want to enable general error logs and slow query error log in the table instead of file

To start logging in table instead of file:

set global log_output = “TABLE”;

To enable general and slow query log:

set global general_log = 1;
set global slow_query_log = 1;

To view the logs:

select * from mysql.slow_log;
select * from mysql.general_log;

For more details visit this link

http://easysolutionweb.com/technology/mysql-server-logs/

you can use toSource method like this

alert(product.toSource());

This is because you are adding your <tbody> tag before <td> in table you cannot print any data without <td>.

So for that you have to make a <div> say #header with position: fixed;

 header
 {
      position: fixed;
 }

make another <div> which will act as <tbody>

tbody
{
    overflow:scroll;
}

Now your header is fixed and the body will scroll. And the header will remain there.

There is no direct way (i.e. using printf or another standard library function) to print it. You will have to write your own function.

/* This code has an obvious bug and another non-obvious one :) */
void printbits(unsigned char v) {
   for (; v; v >>= 1) putchar('0' + (v & 1));
}

If you're using terminal, you can use control codes to print out bytes in natural order:

void printbits(unsigned char v) {
    printf("%*s", (int)ceil(log2(v)) + 1, ""); 
    for (; v; v >>= 1) printf("\x1b[2D%c",'0' + (v & 1));
}

The REST API of Instagram has been discontinued. But you can use GraphQL to get the desired data. Here you can find an overview: https://developers.facebook.com/docs/instagram-api

For those mentioning using Object.keys(localStorage)... don't because it won't work in Firefox (ironically because Firefox is faithful to the spec). Consider this:

localStorage.setItem("key", "value1")
localStorage.setItem("key2", "value2")
localStorage.setItem("getItem", "value3")
localStorage.setItem("setItem", "value4")

Because key, getItem and setItem are prototypal methods Object.keys(localStorage) will only return ["key2"].

You are best to do something like this:

let t = [];
for (let i = 0; i < localStorage.length; i++) {
  t.push(localStorage.key(i));
}

You can get this if the client specifies "https" but the server is only running "http". So, the server isn't expecting to make a secure connection.

Add C:\xampp\php to your PATH environment variable.(My Computer->properties -> Advanced system setting-> Environment Variables->edit path)

For future readers:

This function was abending in Run-time error '13': Type mismatch

Function fnIsNumber(Value) As Boolean
  fnIsNumber = Evaluate("ISNUMBER(0+""" & Value & """)")
End Function

In my case, the function was failing when it ran into a #DIV/0! or N/A value.

To solve it, I had to do this:

Function fnIsNumber(Value) As Boolean
   If CStr(Value) = "Error 2007" Then '<===== This is the important line
      fnIsNumber = False
   Else
      fnIsNumber = Evaluate("ISNUMBER(0+""" & Value & """)")
   End If
End Function

If you are using alphine with docker, do this:

for example :

obj.function(Long.parseLong("600851475143"));

  inflater.inflate(R.menu.mainmenu, menu);
  return true;
}

If an actions in the ActionBar is selected, the onOptionsItemSelected() method is called. It receives the selected action as parameter. Based on this information you code can decide what to do for example:

@Override
public boolean onOptionsItemSelected(MenuItem item) {
  switch (item.getItemId()) {
    case R.id.menuitem1:
      Toast.makeText(this, "Menu Item 1 selected", Toast.LENGTH_SHORT).show();
      break;
    case R.id.menuitem2:
      Toast.makeText(this, "Menu item 2 selected", Toast.LENGTH_SHORT).show();
      break;
  }
  return true;
}

You have to understand how Unix interprets your input.

The standard Unix shell interpolates environment variables, and what are called globs before it passes the parameters to your program. This is a bit different from Windows which makes the program interpret the expansion.

Try this:

 $ echo *

This will echo all the files and directories in your current directory. Before the echo command acts, the shell interpolates the * and expands it, then passes that expanded parameter back to your command. You can see it in action by doing this:

$ set -xv
$ echo *
$ set +xv

The set -xv turns on xtrace and verbose. Verbose echoes the command as entered, and xtrace echos the command that will be executed (that is, after the shell expansion).

Now try this:

$ echo "*"

Note that putting something inside quotes hides the glob expression from the shell, and the shell cannot expand it. Try this:

$ foo="this is the value of foo"
$ echo $foo
$ echo "$foo"
$ echo '$foo'

Note that the shell can still expand environment variables inside double quotes, but not in single quotes.

Now let's look at your statement:

file="home/edward/bank1/fiche/Test*"

The double quotes prevent the shell from expanding the glob expression, so file is equal to the literal home/edward/bank1/finche/Test*. Therefore, you need to do this:

file=/home/edward/bank1/fiche/Test*

The lack of quotes (and the introductory slash which is important!) will now make file equal to all files that match that expression. (There might be more than one!). If there are no files, depending upon the shell, and its settings, the shell may simply set file to that literal string anyway.

You certainly have the right idea:

 file=/home/edward/bank1/fiche/Test*
 if  test -s $file
    then 
        echo "found one"
    else 
       echo "found none"
 fi

However, you still might get found none returned if there is more than one file. Instead, you might get an error in your test command because there are too many parameters.

One way to get around this might be:

if ls /home/edward/bank1/finche/Test* > /dev/null 2>&1
then
    echo "There is at least one match (maybe more)!"
else
    echo "No files found"
fi

In this case, I'm taking advantage of the exit code of the ls command. If ls finds one file it can access, it returns a zero exit code. If it can't find one matching file, it returns a non-zero exit code. The if command merely executes a command, and then if the command returns a zero, it assumes the if statement as true and executes the if clause. If the command returns a non-zero value, the if statement is assumed to be false, and the else clause (if one is available) is executed.

The test command works in a similar fashion. If the test is true, the test command returns a zero. Otherwise, the test command returns a non-zero value. This works great with the if command. In fact, there's an alias to the test command. Try this:

 $ ls -li /bin/test /bin/[

The i prints out the inode. The inode is the real ID of the file. Files with the same ID are the same file. You can see that /bin/test and /bin/[ are the same command. This makes the following two commands the same:

if test -s $file
then
    echo "The file exists"
fi

if [ -s $file ]
then
    echo "The file exists"
fi

it works for me, just change: Provider=Microsoft.Jet.OLEDB.4.0 (VS2013)

OleDbConnection connection = new OleDbConnection(
"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=Z:\\GENERAL\\OFMPTP_PD_SG.MDB");
DataSet DS = new DataSet();
connection.Open();

string query =
@"SELECT * from MONTHLYPROD";
OleDbDataAdapter DBAdapter = new OleDbDataAdapter();
DBAdapter.SelectCommand = new OleDbCommand(query, connection);
DBAdapter.Fill(DS);

Use this: For java

view.getBackground().setColorFilter(Color.parseColor("#343434"), PorterDuff.Mode.SRC_OVER)

for Kotlin

view.background.setColorFilter(Color.parseColor("#343434"),PorterDuff.Mode.SRC_OVER)

you can use PorterDuff.Mode.SRC_ATOP, if your background has rounded corners etc.

There are a few installs you may need to apply for ASP.NET MVC 5 support in Visual Studio 2012. Update 4 seems to include the Web Tools update now.

• Windows 8.1 SDK
• Visual Studio 2012 Update 4
• ASP.NET and Web Tools 2013.1 for Visual Studio 2012

You don't have to install the full Windows 8.1 SDK if you are just looking for the option to build web applications, just the .NET Framework 4.5.1 option in the installer. The full install is about 1.1 GB, but just the .NET installer is only 72 MB.

You have written

background: url('bg.gif') top repeat-y;    
background-size: 490px;

but you will only see the background depending on the size of the container.

if you have an empty container with the background url and whatever the background-size is, you will not see the bg.gif.

If you set the size of the continer to

background: url('bg.gif') top repeat-y;    
background-size: 490px;
height: 490px;
width: 490px;

combined to the code you wrote above, you will be able to see the bg.gif file.

Bit of an amalgamation of the stuff above. But here's my crack at it.

If you are using Jackson 2, the message-converters tag is:

 <ul class="inlineList">
   <li>She</li>
   <li>Needs</li>
   <li>More Padding, Captain!</li>
 </ul>

CSS

 .inlineList {

   justify-content: flex-start; 
   /* Below removes bullets and cleans white-space */
   list-style: none;
   padding: 0;
   /* Bonus: forces no word-wrap */
   white-space: nowrap;
 }
 /* Here, I got you started.

I made a codepen to illustrate: http://codepen.io/agm1984/pen/mOxaEM

I would prefer to keep the "Show Whitespace" button on the toolbar, so that in one click you can toggle it.

Go to Window -> Perspective -> Customize Perspective and enable to show the button on toolbar.

This issue for me was caused by a database mapping error.

I attempted to use a select() call on a datasource with errors in the code behind. My controls were within an update panel and the actual cause was hidden.

Usually, if you can temporarily remove the update panel, asp.net will return a more useful error message.

I found out just now that it might be because of Fast Boot option in Settings > Power

When I have this option off, my application receives a this broadcast but not otherwise.

By the way, I have Android 2.3.3 on HTC Incredible S.

Hope it helps.

Replace the value in select statement itself...

(CASE WHEN Mobile LIKE '966%' THEN (select REPLACE(CAST(Mobile AS nvarchar(MAX)),'966','0')) ELSE Mobile END)

As c69 mentioned there is no way to do it with pure CSS.

but you can use HTML instead:

use

<head>
    <base target="_blank">
</head>

in your HTML <head> tag for making all of page links which not include target attribute to be opened in a new blank window by default. otherwise you can set target attribute for each link like this:

    <a href="/yourlink.html" target="_blank">test-link</a>

and it will override

<head>
    <base target="_blank">
</head>

tag if it was defined previously.

Use %03d in the format specifier for the integer. The 0 means that the number will be zero-filled if it is less than three (in this case) digits.

See the Formatter docs for other modifiers.

SMS Push uses SMS as a carrier, WAP uses download via WAP.

When using IN with a collection-valued parameter you don't need (...):

@NamedQuery(name = "EventLog.viewDatesInclude", 
    query = "SELECT el FROM EventLog el WHERE el.timeMark >= :dateFrom AND " 
    + "el.timeMark <= :dateTo AND " 
    + "el.name IN :inclList") 

Google Chrome seems to return false positives on this one:

var isTouch = 'ontouchstart' in document.documentElement;

I suppose it has something to do with its ability to "emulate touch events" (F12 -> settings at lower right corner -> "overrides" tab -> last checkbox). I know it's turned off by default but that's what I connect the change in results with (the "in" method used to work in Chrome). However, this seems to be working, as far as I have tested:

var isTouch = !!("undefined" != typeof document.documentElement.ontouchstart);

All browsers I've run that code on state the typeof is "object" but I feel more certain knowing that it's whatever but undefined :-)

Tested on IE7, IE8, IE9, IE10, Chrome 23.0.1271.64, Chrome for iPad 21.0.1180.80 and iPad Safari. It would be cool if someone made some more tests and shared the results.

I don't think there is one in JRE. You can find similar functions in other packages like Apache HttpClient. If you don't use any other packages, you just have to write your own. It's not that hard. Here is what I use,

public class QueryString {

 private Map<String, List<String>> parameters;

 public QueryString(String qs) {
  parameters = new TreeMap<String, List<String>>();

  // Parse query string
     String pairs[] = qs.split("&");
     for (String pair : pairs) {
            String name;
            String value;
            int pos = pair.indexOf('=');
            // for "n=", the value is "", for "n", the value is null
         if (pos == -1) {
          name = pair;
          value = null;
         } else {
       try {
        name = URLDecoder.decode(pair.substring(0, pos), "UTF-8");
              value = URLDecoder.decode(pair.substring(pos+1, pair.length()), "UTF-8");            
       } catch (UnsupportedEncodingException e) {
        // Not really possible, throw unchecked
           throw new IllegalStateException("No UTF-8");
       }
         }
         List<String> list = parameters.get(name);
         if (list == null) {
          list = new ArrayList<String>();
          parameters.put(name, list);
         }
         list.add(value);
     }
 }

 public String getParameter(String name) {        
  List<String> values = parameters.get(name);
  if (values == null)
   return null;

  if (values.size() == 0)
   return "";

  return values.get(0);
 }

 public String[] getParameterValues(String name) {        
  List<String> values = parameters.get(name);
  if (values == null)
   return null;

  return (String[])values.toArray(new String[values.size()]);
 }

 public Enumeration<String> getParameterNames() {  
  return Collections.enumeration(parameters.keySet()); 
 }

 public Map<String, String[]> getParameterMap() {
  Map<String, String[]> map = new TreeMap<String, String[]>();
  for (Map.Entry<String, List<String>> entry : parameters.entrySet()) {
   List<String> list = entry.getValue();
   String[] values;
   if (list == null)
    values = null;
   else
    values = (String[]) list.toArray(new String[list.size()]);
   map.put(entry.getKey(), values);
  }
  return map;
 } 
}

With Equals() you can also use a Yoda condition:

if ( ! "-1".Equals(myString) )

The ~ selector is in fact the General sibling combinator (renamed to Subsequent-sibling combinator in selectors Level 4):

The general sibling combinator is made of the "tilde" (U+007E, ~) character that separates two sequences of simple selectors. The elements represented by the two sequences share the same parent in the document tree and the element represented by the first sequence precedes (not necessarily immediately) the element represented by the second one.

Consider the following example:

.a ~ .b {_x000D_
  background-color: powderblue;_x000D_
}

<ul>_x000D_
  <li class="b">1st</li>_x000D_
  <li class="a">2nd</li>_x000D_
  <li>3rd</li>_x000D_
  <li class="b">4th</li>_x000D_
  <li class="b">5th</li>_x000D_
</ul>

.a ~ .b matches the 4th and 5th list item because they:

• Are .b elements
• Are siblings of .a
• Appear after .a in HTML source order.

Likewise, .check:checked ~ .content matches all .content elements that are siblings of .check:checked and appear after it.

I think the easiest (and best) way to do this is to subclass your global view and use hitTest:withEvent method to listen to any touch. Touches on keyboard aren't registered, so hitTest:withEvent is only called when you touch/scroll/swipe/pinch... somewhere else, then call [self endEditing:YES].

This is better than using touchesBegan because touchesBegan are not called if you click on a button on top of the view. It is better than UITapGestureRecognizer which can't recognize a scrolling gesture for example. It is also better than using a dim screen because in a complexe and dynamic user interface, you can't put dim screen everywhere. Moreover, it doesn't block other actions, you don't need to tap twice to select a button outside (like in the case of a UIPopover).

Also, it's better than calling [textField resignFirstResponder], because you may have many text fields on screen, so this works for all of them.

If you have a newer distro with a newer systemd (systemd version 236 or newer), you can set the values of StandardOutput or StandardError to file:YOUR_ABSPATH_FILENAME.

Long story:

In newer versions of systemd there is a relatively new option (the github request is from 2016 ish and the enhancement is merged/closed 2017 ish) where you can set the values of StandardOutput or StandardError to file:YOUR_ABSPATH_FILENAME. The file:path option is documented in the most recent systemd.exec man page.

This new feature is relatively new and so is not available for older distros like centos-7 (or any centos before that).

An example how to avoid null e.g. use filter before groupingBy

Filter out the null instances before groupingBy.

MyObjectlist.stream()
            .filter(p -> p.getSomeInstance() != null)
            .collect(Collectors.groupingBy(MyObject::getSomeInstance));

The documentation says:

When you need to set attributes that are also mapped to a JavaScript dot-property (such as href, style, src or event-handlers), favour that mapping instead.

So, just change id, value assignment and you should be done.

GCC documentation says the following about the difference between the two:

Both user and system header files are included using the preprocessing directive ‘#include’. It has two variants:

#include <file>

This variant is used for system header files. It searches for a file named file in a standard list of system directories. You can prepend directories to this list with the -I option (see Invocation).

#include "file"

This variant is used for header files of your own program. It searches for a file named file first in the directory containing the current file, then in the quote directories and then the same directories used for <file>. You can prepend directories to the list of quote directories with the -iquote option. The argument of ‘#include’, whether delimited with quote marks or angle brackets, behaves like a string constant in that comments are not recognized, and macro names are not expanded. Thus, #include <x/*y> specifies inclusion of a system header file named x/*y.

However, if backslashes occur within file, they are considered ordinary text characters, not escape characters. None of the character escape sequences appropriate to string constants in C are processed. Thus,#include "x\n\\y"specifies a filename containing three backslashes. (Some systems interpret ‘\’ as a pathname separator. All of these also interpret ‘/’ the same way. It is most portable to use only ‘/’.)

It is an error if there is anything (other than comments) on the line after the file name.

The simplest solution I've found that doesn't require a plugin:

document.addEventListener('touchstart', handleTouchStart, false);        
document.addEventListener('touchmove', handleTouchMove, false);
var xDown = null;                                                        
var yDown = null;  

function handleTouchStart(evt) {                                         
    xDown = evt.touches[0].clientX;                                      
    yDown = evt.touches[0].clientY;                                      
}; 

function handleTouchMove(evt) {
    if ( ! xDown || ! yDown ) {
        return;
    }
    var xUp = evt.touches[0].clientX;                                    
    var yUp = evt.touches[0].clientY;
    var xDiff = xDown - xUp;
    var yDiff = yDown - yUp;

    if ( Math.abs( xDiff ) > Math.abs( yDiff ) ) {/*most significant*/
        if ( xDiff > 0 ) {
        /* left swipe */ 
        } else {
        /* right swipe */
        }                       
    } else {
        if ( yDiff > 0 ) {
        /* up swipe */ 
        } else { 
        /* down swipe */
        }                                                                 
    }
    /* reset values */
    xDown = null;
    yDown = null;                                             
};

Function on swift 3 scroll to bottom

 override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(false)
        //scroll down
        if lists.count > 2 {
            let numberOfSections = self.tableView.numberOfSections
            let numberOfRows = self.tableView.numberOfRows(inSection: numberOfSections-1)
            let indexPath = IndexPath(row: numberOfRows-1 , section: numberOfSections-1)
            self.tableView.scrollToRow(at: indexPath, at: UITableViewScrollPosition.middle, animated: true)
        }
    }

You can use a jQuery plugin (breedjs) that provides sort, filter and pagination:

HTML:

<table>
  <thead>
    <tr>
      <th sort='name'>Name</th>
      <th>Phone</th>
      <th sort='city'>City</th>
      <th>Speciality</th>
    </tr>
  </thead>
  <tbody>
    <tr b-scope="people" b-loop="person in people">
      <td b-sort="name">{{person.name}}</td>
      <td>{{person.phone}}</td>
      <td b-sort="city">{{person.city}}</td>
      <td>{{person.speciality}}</td>
    </tr>
  </tbody>
</table>

JS:

$(function(){
  var data = {
    people: [
      {name: 'c', phone: 123, city: 'b', speciality: 'a'},
      {name: 'b', phone: 345, city: 'a', speciality: 'c'},
      {name: 'a', phone: 234, city: 'c', speciality: 'b'},
    ]
  };
  breed.run({
    scope: 'people',
    input: data
  });
  $("th[sort]").click(function(){
    breed.sort({
      scope: 'people',
      selector: $(this).attr('sort')
    });
  });
});

Working example on fiddle

so simple :

 outline-color : blue !important;

the whole CSS for my react-boostrap button is:

.custom-btn {
    font-size:1.9em;
    background: #2f5bff;
    border: 2px solid #78e4ff;
    border-radius: 3px;
    padding: 50px 70px;
    outline-color : blue !important;
    text-transform: uppercase;
    user-select: auto;
    -moz-box-shadow: inset 0 0 4px rgba(0,0,0,0.2);
    -webkit-box-shadow: inset 0 0 4px rgba(0, 0, 0, 0.2);
    -webkit-border-radius: 3px;
    -moz-border-radius: 3px;
}

If you want to Iterate through the Fields and Values of a struct then you can use the below Go code as a reference.

package main

import (
    "fmt"
    "reflect"
)

type Student struct {
    Fname  string
    Lname  string
    City   string
    Mobile int64
}

func main() {
    s := Student{"Chetan", "Kumar", "Bangalore", 7777777777}
    v := reflect.ValueOf(s)
    typeOfS := v.Type()

    for i := 0; i< v.NumField(); i++ {
        fmt.Printf("Field: %s\tValue: %v\n", typeOfS.Field(i).Name, v.Field(i).Interface())
    }
}

Note: If the Fields in your struct are not exported then the v.Field(i).Interface() will give panic panic: reflect.Value.Interface: cannot return value obtained from unexported field or method.

You have a column InvoiceID in the Invoices table and also in the InvoiceLineItems table. There is no way for the query execution engine to know which one you want returned.

Adding a table alias will help:

SELECT V.VendorName, I.InvoiceID, IL.InvoiceSequence, IL.InvoiceLineItemAmount
FROM Vendors V
JOIN Invoices I ON (...)
JOIN InvoiceLineItems IL ON (...)
WHERE ...
ORDER BY V.VendorName, I.InvoiceID, IL.InvoiceSequence, IL.InvoiceLineItemAmount
