The Series class has a pandas.Series.dt accessor object with several useful datetime attributes, including dt.days. Access this attribute via:

timedelta_series.dt.days

You can also get the seconds and microseconds attributes in the same way.

var full_address = req.protocol + "://" + req.headers.host + req.originalUrl;

or

var full_address = req.protocol + "://" + req.headers.host + req.baseUrl;

In a project using vs 2010, I was only able to solve the problem by installing an older version of the package that I needed via Package Manager Console.

This command worked:

PM> Install-Package EPPlus -Version 4.5.3.1

This command did not work:

PM> Install-Package EPPlus -Version 4.5.3.2

Although silly mistake but make sure to use correct module name and respect capitalization

I installed this package via command line as pip install cx_oracle in my windows machine. While importing it in spyder as cx_oracle, it kept on giving following error:

ModuleNotFoundError: No module named 'cx_oracle'.

Upon correcting the module name in import command to cx_Oracle (i.e. capital letter 'O' in oracle), it was a successful import.

Yes, you can input multiple items from cin, using exactly the syntax you describe. The result is essentially identical to:

cin >> a;
cin >> b;
cin >> c;

This is due to a technique called "operator chaining".

Each call to operator>>(istream&, T) (where T is some arbitrary type) returns a reference to its first argument. So cin >> a returns cin, which can be used as (cin>>a)>>b and so forth.

Note that each call to operator>>(istream&, T) first consumes all whitespace characters, then as many characters as is required to satisfy the input operation, up to (but not including) the first next whitespace character, invalid character, or EOF.

You might have to re-check the order in which you are merging the files, it should be something like:

1. jquery.min.js
2. jquery-ui.js
3. any third party plugins you loading
4. your custom JS

At the time of writing this, the current version of Tomcat 7 (7.0.41) has a built-in CORS filter http://tomcat.apache.org/tomcat-7.0-doc/config/filter.html#CORS_Filter

While I really admire the answer from @hoge both for a very concise technique and a wrapper function to generalize it and I encourage upvotes for it, I am compelled to comment on the other two answers that use temp files (it gnaws at me like fingernails on a chalkboard!).

Assuming the file is not huge, you can force the pipeline to operate in discrete sections--thereby obviating the need for a temp file--with judicious use of parentheses:

(Get-Content $file | Select-Object -Skip 1) | Set-Content $file

... or in short form:

(gc $file | select -Skip 1) | sc $file

In my case, the backup file was compressed, but the file extension didn't indicate this, didn't end in .zip, .tgz, etc. Once I decompressed my backup file I was able to import it.

You are right, this is related to SQL injection, which is a vulnerability that allows a malicioius user to execute arbitrary statements against your database. This old time favorite XKCD comic illustrates the concept:

In your example, if you just use:

var query = "SELECT empSalary from employee where salary = " + txtSalary.Text;
// and proceed to execute this query

You are open to SQL injection. For example, say someone enters txtSalary:

1; UPDATE employee SET salary = 9999999 WHERE empID = 10; --
1; DROP TABLE employee; --
// etc.

When you execute this query, it will perform a SELECT and an UPDATE or DROP, or whatever they wanted. The -- at the end simply comments out the rest of your query, which would be useful in the attack if you were concatenating anything after txtSalary.Text.

The correct way is to use parameterized queries, eg (C#):

SqlCommand query =  new SqlCommand("SELECT empSalary FROM employee 
                                    WHERE salary = @sal;");
query.Parameters.AddWithValue("@sal", txtSalary.Text);

With that, you can safely execute the query.

For reference on how to avoid SQL injection in several other languages, check bobby-tables.com, a website maintained by a SO user.

A few examples follow, going from basic through to adding transformations after the request and/or error handling:

Basic:

// Implementation code where T is the returned data shape
function api<T>(url: string): Promise<T> {
  return fetch(url)
    .then(response => {
      if (!response.ok) {
        throw new Error(response.statusText)
      }
      return response.json<T>()
    })

}

// Consumer
api<{ title: string; message: string }>('v1/posts/1')
  .then(({ title, message }) => {
    console.log(title, message)
  })
  .catch(error => {
    /* show error message */
  })

Data transformations:

Often you may need to do some tweaks to the data before its passed to the consumer, for example, unwrapping a top level data attribute. This is straight forward:

function api<T>(url: string): Promise<T> {
  return fetch(url)
    .then(response => {
      if (!response.ok) {
        throw new Error(response.statusText)
      }
      return response.json<{ data: T }>()
    })
    .then(data => { /* <-- data inferred as { data: T }*/
      return data.data
    })
}

// Consumer - consumer remains the same
api<{ title: string; message: string }>('v1/posts/1')
  .then(({ title, message }) => {
    console.log(title, message)
  })
  .catch(error => {
    /* show error message */
  })

Error handling:

I'd argue that you shouldn't be directly error catching directly within this service, instead, just allowing it to bubble, but if you need to, you can do the following:

function api<T>(url: string): Promise<T> {
  return fetch(url)
    .then(response => {
      if (!response.ok) {
        throw new Error(response.statusText)
      }
      return response.json<{ data: T }>()
    })
    .then(data => {
      return data.data
    })
    .catch((error: Error) => {
      externalErrorLogging.error(error) /* <-- made up logging service */
      throw error /* <-- rethrow the error so consumer can still catch it */
    })
}

// Consumer - consumer remains the same
api<{ title: string; message: string }>('v1/posts/1')
  .then(({ title, message }) => {
    console.log(title, message)
  })
  .catch(error => {
    /* show error message */
  })

Edit

There has been some changes since writing this answer a while ago. As mentioned in the comments, response.json<T> is no longer valid. Not sure, couldn't find where it was removed.

For later releases, you can do:

// Standard variation
function api<T>(url: string): Promise<T> {
  return fetch(url)
    .then(response => {
      if (!response.ok) {
        throw new Error(response.statusText)
      }
      return response.json() as Promise<T>
    })
}


// For the "unwrapping" variation

function api<T>(url: string): Promise<T> {
  return fetch(url)
    .then(response => {
      if (!response.ok) {
        throw new Error(response.statusText)
      }
      return response.json() as Promise<{ data: T }>
    })
    .then(data => {
        return data.data
    })
}

The generic Returns<T> method can handle this situation nicely.

_mock.Setup(x => x.DoSomething(It.IsAny<string>())).Returns<string>(x => x);

Or if the method requires multiple inputs, specify them like so:

_mock.Setup(x => x.DoSomething(It.IsAny<string>(), It.IsAny<int>())).Returns((string x, int y) => x);

I ended on this:

function sort_array_of_array(&$array, $subfield)
{
    $sortarray = array();
    foreach ($array as $key => $row)
    {
        $sortarray[$key] = $row[$subfield];
    }

    array_multisort($sortarray, SORT_ASC, $array);
}

Just call the function, passing the array and the name of the field of the second level array. Like:

sort_array_of_array($inventory, 'price');

None of the above answers fixed this issue for me. I did it as following (Laravel with Ubuntu server):

<?php
     $footerFile = '/var/www/website/main/resources/views/emails/elements/emailfooter.blade.php';
     include($footerFile);
?>

In my case it was a permission issue. I had to:

• chmod a+wrx the image,

then it worked.

Below are some common Big-O functions while analyzing algorithms.

• O(1) - constant time
• O(log(n)) - logarithmic time
• O((log(n))^c) - polylogarithmic time
• O(n) - linear time
• O(n²) - quadratic time
• O(n^c) - polynomial time
• O(cⁿ) - exponential time
• O(n!) - factorial time

(n = size of input, c = some constant)

Here is the model graph representing Big-O complexity of some functions

Also $( "#container" ).find( "div.robotarm" );
is equal to: $( "div.robotarm", "#container" )

You can use ::after to create a 0px-height block after the <h4>, which effectively moves anything after the <h4> to the next line:

h4 {_x000D_
  display: inline;_x000D_
}_x000D_
h4::after {_x000D_
  content: "";_x000D_
  display: block;_x000D_
}

<ul>_x000D_
  <li>_x000D_
    Text, text, text, text, text. <h4>Sub header</h4>_x000D_
    Text, text, text, text, text._x000D_
  </li>_x000D_
</ul>

You can also try this, if this is what you need:

<style type="text/css">
   ....
   table td div {height:20px;overflow-y:hidden;}
   table td.col1 div {width:100px;}
   table td.col2 div {width:300px;}
</style>


<table>
<tbody>
    <tr><td class="col1"><div>test</div></td></tr>
    <tr><td class="col2"><div>test</div></td></tr>
</tbody>
</table>

kieron's answer contains w3schools ref. to which nobody rely , bobince's answer gives link , which actually tells native implementation of IE ,

so here is the original documentation quoted to rightly understand what readystate represents :

The XMLHttpRequest object can be in several states. The readyState attribute must return the current state, which must be one of the following values:

UNSENT (numeric value 0)
The object has been constructed.

OPENED (numeric value 1)
The open() method has been successfully invoked. During this state request headers can be set using setRequestHeader() and the request can be made using the send() method.

HEADERS_RECEIVED (numeric value 2)
All redirects (if any) have been followed and all HTTP headers of the final response have been received. Several response members of the object are now available.

LOADING (numeric value 3)
The response entity body is being received.

DONE (numeric value 4)
The data transfer has been completed or something went wrong during the transfer (e.g. infinite redirects).

Please Read here : W3C Explaination Of ReadyState

1. Right click on project then select new->directory. Create a new directory and name it "test".
2. Right click on "test" folder then select Mark Directory As->Test Sources Root
3. Click on Navigate->Test->Create New Test
   Select Testing library(JUnit4 or any)
   Specify Class Name
   Select Member

That's it. We can modify the directory structure as per our need. Good luck!

Try these link types actually works for me.

It might be not totally related, but since the question mentioned react uses case (and I keep bumping into this SO thread): There is one important aspect of the double arrow function which is not explicitly mentioned here. Only the 'first' arrow(function) gets named (and thus 'distinguishable' by the run-time), any following arrows are anonymous and from React point of view count as a 'new' object on every render.

Thus double arrow function will cause any PureComponent to rerender all the time.

Example

You have a parent component with a change handler as:

handleChange = task => event => { ... operations which uses both task and event... };

and with a render like:

{ tasks.map(task => <MyTask handleChange={this.handleChange(task)}/> }

handleChange then used on an input or click. And this all works and looks very nice. BUT it means that any change that will cause the parent to rerender (like a completely unrelated state change) will also re-render ALL of your MyTask as well even though they are PureComponents.

This can be alleviated many ways such as passing the 'outmost' arrow and the object you would feed it with or writing a custom shouldUpdate function or going back to basics such as writing named functions (and binding the this manually...)

The simplest non recursive way is:

for d in */; do
    echo "$d"
done

The / at the end tells, use directories only.

There is no need for

• find
• awk
• ...

what about this

--// Convert NVARCHAR to DATETIME
DECLARE @date DATETIME = (SELECT convert(DATETIME, '2013-08-29 13:55:48', 120))
--// Convert DATETIME to custom NVARCHAR FORMAT
SELECT 
RIGHT('00'+ CAST(DAY(@date) AS NVARCHAR),2) + '-' +
RIGHT('00'+ CAST(MONTH(@date) AS NVARCHAR),2) + '-' + 
CAST(YEAR(@date) AS NVARCHAR) + ' ' + 
CAST(CONVERT(TIME,@date) AS NVARCHAR)

result: '29-08-2013 13:55:48.0000000'

componentDidUpdate(prevProps){ 

    if (this.state.authToken==null&&prevProps.authToken==null) {
      AccountKit.getCurrentAccessToken()
      .then(token => {
        if (token) {
          AccountKit.getCurrentAccount().then(account => {
            this.setState({
              authToken: token,
              loggedAccount: account
            });
          });
        } else {
          console.log("No user account logged");
        }
      })
      .catch(e => console.log("Failed to get current access token", e));

    }
}

There is a new discussion about this (https://github.com/angular/angular/issues/4933). So far there is only some hacks that allows to clear the form, like recreating the whole form after submitting: https://embed.plnkr.co/kMPjjJ1TWuYGVNlnQXrU/

I had the same problem - and I have read all these answers, but unfortunately none of them worked for me. Eventually I tried removing this line

%\usepackage[latin1]{inputenc}

and all errors disappeared.

This answer is widely oriented around Git Flow. The tables have been generated with the nice ASCII Table Generator, and the history trees with this wonderful command (aliased as git lg):

git log --graph --abbrev-commit --decorate --date=format:'%Y-%m-%d %H:%M:%S' --format=format:'%C(bold blue)%h%C(reset) - %C(bold cyan)%ad%C(reset) %C(bold green)(%ar)%C(reset)%C(bold yellow)%d%C(reset)%n''          %C(white)%s%C(reset) %C(dim white)- %an%C(reset)'

Tables are in reverse chronological order to be more consistent with the history trees. See also the difference between git merge and git merge --no-ff first (you usually want to use git merge --no-ff as it makes your history look closer to the reality):

git merge vs git rebase

First point: always merge features into develop, never rebase develop from features. This is a consequence of the Golden Rule of Rebasing:

The golden rule of git rebase is to never use it on public branches.

In other words:

Never rebase anything you've pushed somewhere.

I would personally add: unless it's a feature branch AND you and your team are aware of the consequences.

So the question of git merge vs git rebase applies almost only to the feature branches (in the following examples, --no-ff has always been used when merging). Note that since I'm not sure there's one better solution (a debate exists), I'll only provide how both commands behave. In my case, I prefer using git rebase as it produces a nicer history tree :)

git cherry-pick

When you just need one specific commit, git cherry-pick is a nice solution (the -x option appends a line that says "(cherry picked from commit...)" to the original commit message body, so it's usually a good idea to use it - git log <commit_sha1> to see it):

git pull --rebase

I am not sure I can explain it better than Derek Gourlay... Basically, use git pull --rebase instead of git pull :) What's missing in the article though, is that you can enable it by default:

git config --global pull.rebase true

git rerere

Again, nicely explained here. But put simply, if you enable it, you won't have to resolve the same conflict multiple times anymore.

use isinstance(v, type_name) or type(v) is type_name or type(v) == type_name,

where type_name can be one of the following:

• None
• bool
• int
• float
• complex
• str
• list
• tuple
• set
• dict

and, of course,

• custom types (classes)

I tried adding a block like so:

@section styles{
    <link rel="Stylesheet" href="@Href("~/Content/MyStyles.css")" />
}

And a corresponding block in the _Layout.cshtml file:

<head>
<title>@ViewBag.Title</title>
@RenderSection("styles", false);
</head>

Which works! But I can't help but think there's a better way. UPDATE: Added "false" in the @RenderSection statement so your view won't 'splode when you neglect to add a @section called head.

sed -i '/pattern/d' file

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

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

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

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

For C# NUnit, you need to convert WebDriver to JSExecuter and then execute the script to check if document.ready state is complete or not. Check below code for reference:

 public static void WaitForLoad(IWebDriver driver)
    {
        IJavaScriptExecutor js = (IJavaScriptExecutor)driver;
        int timeoutSec = 15;
        WebDriverWait wait = new WebDriverWait(driver, new TimeSpan(0, 0, timeoutSec));
        wait.Until(wd => js.ExecuteScript("return document.readyState").ToString() == "complete");
    }

This will wait until the condition is satisfied or timeout.

Any variable declared outside of a function is assumed to be global, it's only when declaring them from inside of functions (except constructors) that you must specify that the variable be global.

you can also use this code

//test" class="btn btn-primary pull-right">

I would like to explain the concepts from the perspective of JavaScript prototype inheritance. Hopefully help to understand.

There are three options to define the scope of a directive:

1. scope: false: Angular default. The directive's scope is exactly the one of its parent scope (parentScope).
2. scope: true: Angular creates a scope for this directive. The scope prototypically inherits from parentScope.
3. scope: {...}: isolated scope is explained below.

Specifying scope: {...} defines an isolatedScope. An isolatedScope does not inherit properties from parentScope, although isolatedScope.$parent === parentScope. It is defined through:

app.directive("myDirective", function() {
    return {
        scope: {
            ... // defining scope means that 'no inheritance from parent'.
        },
    }
})

isolatedScope does not have direct access to parentScope. But sometimes the directive needs to communicate with the parentScope. They communicate through @, = and &. The topic about using symbols @, = and & are talking about scenarios using isolatedScope.

It is usually used for some common components shared by different pages, like Modals. An isolated scope prevents polluting the global scope and is easy to share among pages.

Here is a basic directive: http://jsfiddle.net/7t984sf9/5/. An image to illustrate is:

@: one-way binding

@ simply passes the property from parentScope to isolatedScope. It is called one-way binding, which means you cannot modify the value of parentScope properties. If you are familiar with JavaScript inheritance, you can understand these two scenarios easily:

• If the binding property is a primitive type, like interpolatedProp in the example: you can modify interpolatedProp, but parentProp1 would not be changed. However, if you change the value of parentProp1, interpolatedProp will be overwritten with the new value (when angular $digest).

• If the binding property is some object, like parentObj: since the one passed to isolatedScope is a reference, modifying the value will trigger this error:

  TypeError: Cannot assign to read only property 'x' of {"x":1,"y":2}

=: two-way binding

= is called two-way binding, which means any modification in childScope will also update the value in parentScope, and vice versa. This rule works for both primitives and objects. If you change the binding type of parentObj to be =, you will find that you can modify the value of parentObj.x. A typical example is ngModel.

&: function binding

& allows the directive to call some parentScope function and pass in some value from the directive. For example, check JSFiddle: & in directive scope.

Define a clickable template in the directive like:

<div ng-click="vm.onCheck({valueFromDirective: vm.value + ' is from the directive'})">

And use the directive like:

<div my-checkbox value="vm.myValue" on-check="vm.myFunction(valueFromDirective)"></div>

The variable valueFromDirective is passed from the directive to the parent controller through {valueFromDirective: ....

Reference: Understanding Scopes

I tried some of the other solutions listed here, but during unit testing the code would throw exceptions I wanted to ignore. I ended up creating the following recursive search method that will ignore certain exceptions like PathTooLongException and UnauthorizedAccessException.

    private IEnumerable<string> RecursiveFileSearch(string path, string pattern, ICollection<string> filePathCollector = null)
    {
        try
        {
            filePathCollector = filePathCollector ?? new LinkedList<string>();

            var matchingFilePaths = Directory.GetFiles(path, pattern);

            foreach(var matchingFile in matchingFilePaths)
            {
                filePathCollector.Add(matchingFile);
            }

            var subDirectories = Directory.EnumerateDirectories(path);

            foreach (var subDirectory in subDirectories)
            {
                RecursiveFileSearch(subDirectory, pattern, filePathCollector);
            }

            return filePathCollector;
        }
        catch (Exception error)
        {
            bool isIgnorableError = error is PathTooLongException ||
                error is UnauthorizedAccessException;

            if (isIgnorableError)
            {
                return Enumerable.Empty<string>();
            }

            throw error;
        }
    }

Quoting the Scheduling Repeating Alarms - Understand the Trade-offs docs:

A common scenario for triggering an operation outside the lifetime of your app is syncing data with a server. This is a case where you might be tempted to use a repeating alarm. But if you own the server that is hosting your app's data, using Google Cloud Messaging (GCM) in conjunction with sync adapter is a better solution than AlarmManager. A sync adapter gives you all the same scheduling options as AlarmManager, but it offers you significantly more flexibility.

So, based on this, the best way to schedule a server call is using Google Cloud Messaging (GCM) in conjunction with sync adapter.

This work for me!

$(document).ready(function() {
    $(document).on("click", "#tableId tbody tr", function() {
        //some think
    });
});

I've seen similar answers, but nothing exactly like what worked for me. On Linux, I had to kill and restart my gpg-agent with:

$ pkill gpg-agent
$ gpg-agent --daemon
$ git commit ...

This did the trick for me. It looks like you do need to have user.signingkey set to your private key as well from what some other comments are saying.

$ git config --global user.signingkey [your_key_hash]

1. There is no such thing as xhr.file = file;; the file object is not supposed to be attached this way.

2. xhr.send(file) doesn't send the file. You have to use the FormData object to wrap the file into a multipart/form-data post data object:

   var formData = new FormData();
   formData.append("thefile", file);
   xhr.send(formData);
   

After that, the file can be access in $_FILES['thefile'] (if you are using PHP).

Remember, MDC and Mozilla Hack demos are your best friends.

EDIT: The (2) above was incorrect. It does send the file, but it would send it as raw post data. That means you would have to parse it yourself on the server (and it's often not possible, depend on server configuration). Read how to get raw post data in PHP here.

Since people will be coming from Google, make sure you're in the right database.

Running SQL in the 'master' database will often return this error.

Instead of using the placeholder text, you'll want to set the actual text property of the field to MM/YYYY, set the delegate of the text field and listen for this method:

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {     // update the text of the label } 

Inside that method, you can figure out what the user has typed as they type, which will allow you to update the label accordingly.

Building on @boulder_ruby's answer, this is what I'm looking for, assuming us_eco contains the CSV table as from my gist.

CSV.open('outfile.txt','wb', col_sep: "\t") do |csvfile|
  csvfile << us_eco.first.keys
  us_eco.each do |row|
    csvfile << row.values
  end
end

This's Because!

1. The timeout function callbacks are all running well after the completion of the loop. In fact, as timers go, even if it was setTimeout(.., 0) on each iteration, all those function callbacks would still run strictly after the completion of the loop, that's why 3 was reflected!
2. all two of those functions, though they are defined separately in each loop iteration, are closed over the same shared global scope, which has, in fact, only one i in it.

the Solution's declaring a single scope for each iteration by using a self-function executed(anonymous one or better IIFE) and having a copy of i in it, like this:

for (var i = 1; i <= 2; i++) {

     (function(){

         var j = i;
         setTimeout(function() { console.log(j) }, 100);

     })();

}

the cleaner one would be

for (var i = 1; i <= 2; i++) {

     (function(i){ 

         setTimeout(function() { console.log(i) }, 100);

     })(i);

}

The use of an IIFE(self-executed function) inside each iteration created a new scope for each iteration, which gave our timeout function callbacks the opportunity to close over a new scope for each iteration, one which had a variable with the right per-iteration value in it for us to access.

For trimming your string, Go's "strings" package have TrimSpace(), Trim() function that trims leading and trailing spaces.

Check the documentation for more information.

For cases like the one you described, I found this to work. It's relatively short and sweet:

 let attributedString = NSMutableAttributedString(string: "follow the yellow brick road") //can essentially come from a textField.text as well (will need to unwrap though)
 let text = "follow the yellow brick road"
 let str = NSString(string: text) 
 let theRange = str.rangeOfString("yellow")
 attributedString.addAttribute(NSForegroundColorAttributeName, value: UIColor.yellowColor(), range: theRange)

The answers are missing a specific time of day timer here is on the next hour:

NSCalendarUnit allUnits = NSCalendarUnitYear   | NSCalendarUnitMonth |
                          NSCalendarUnitDay    | NSCalendarUnitHour  |
                          NSCalendarUnitMinute | NSCalendarUnitSecond;

NSCalendar *calendar = [[ NSCalendar alloc]  
                          initWithCalendarIdentifier:NSGregorianCalendar];

NSDateComponents *weekdayComponents = [calendar components: allUnits 
                                                  fromDate: [ NSDate date ] ];

[ weekdayComponents setHour: weekdayComponents.hour + 1 ];
[ weekdayComponents setMinute: 0 ];
[ weekdayComponents setSecond: 0 ];

NSDate *nextTime = [ calendar dateFromComponents: weekdayComponents ];

refreshTimer = [[ NSTimer alloc ] initWithFireDate: nextTime
                                          interval: 0.0
                                            target: self
                                          selector: @selector( doRefresh )
                                          userInfo: nil repeats: NO ];

[[NSRunLoop currentRunLoop] addTimer: refreshTimer forMode: NSDefaultRunLoopMode];

Of course, substitute "doRefresh" with your class's desired method

try to create the calendar object once and make the allUnits a static for efficiency.

adding one to hour component works just fine, no need for a midnight test (link)

You mark the selected item on the <option> tag, not the <select> tag.

So your code should read something like this:

<select>
    <option value="January"<?php if ($row[month] == 'January') echo ' selected="selected"'; ?>>January</option>
    <option value="February"<?php if ($row[month] == 'February') echo ' selected="selected"'; ?>>February</option>
    ...
    ...
    <option value="December"<?php if ($row[month] == 'December') echo ' selected="selected"'; ?>>December</option>
</select>

You can make this less repetitive by putting all the month names in an array and using a basic foreach over them.

Answering in generalities:

1. Yes, usually.
2. See More Info Here
3. Yes, because each has a different JS processing engine, however, in running a test on the site below, the switch always out performed the if, elseif on a large number of iterations.

Test site

FIRST, if you want to be able to access man1.py from man1test.py AND manModules.py from man1.py, you need to properly setup your files as packages and modules.

Packages are a way of structuring Python’s module namespace by using “dotted module names”. For example, the module name A.B designates a submodule named B in a package named A.

...

When importing the package, Python searches through the directories on sys.path looking for the package subdirectory.

The __init__.py files are required to make Python treat the directories as containing packages; this is done to prevent directories with a common name, such as string, from unintentionally hiding valid modules that occur later on the module search path.

You need to set it up to something like this:

man
|- __init__.py
|- Mans
   |- __init__.py
   |- man1.py
|- MansTest
   |- __init.__.py
   |- SoftLib
      |- Soft
         |- __init__.py
         |- SoftWork
            |- __init__.py
            |- manModules.py
      |- Unittests
         |- __init__.py
         |- man1test.py

SECOND, for the "ModuleNotFoundError: No module named 'Soft'" error caused by from ...Mans import man1 in man1test.py, the documented solution to that is to add man1.py to sys.path since Mans is outside the MansTest package. See The Module Search Path from the Python documentation. But if you don't want to modify sys.path directly, you can also modify PYTHONPATH:

sys.path is initialized from these locations:

• The directory containing the input script (or the current directory when no file is specified).
• PYTHONPATH (a list of directory names, with the same syntax as the shell variable PATH).
• The installation-dependent default.

THIRD, for from ...MansTest.SoftLib import Soft which you said "was to facilitate the aforementioned import statement in man1.py", that's now how imports work. If you want to import Soft.SoftLib in man1.py, you have to setup man1.py to find Soft.SoftLib and import it there directly.

With that said, here's how I got it to work.

man1.py:

from Soft.SoftWork.manModules import *
# no change to import statement but need to add Soft to PYTHONPATH

def foo():
    print("called foo in man1.py")
    print("foo call module1 from manModules: " + module1())

man1test.py

# no need for "from ...MansTest.SoftLib import Soft" to facilitate importing..
from ...Mans import man1

man1.foo()

manModules.py

def module1():
    return "module1 in manModules"

Terminal output:

$ python3 -m man.MansTest.Unittests.man1test
Traceback (most recent call last):
  ...
    from ...Mans import man1
  File "/temp/man/Mans/man1.py", line 2, in <module>
    from Soft.SoftWork.manModules import *
ModuleNotFoundError: No module named 'Soft'

$ PYTHONPATH=$PYTHONPATH:/temp/man/MansTest/SoftLib
$ export PYTHONPATH
$ echo $PYTHONPATH
:/temp/man/MansTest/SoftLib
$ python3 -m man.MansTest.Unittests.man1test
called foo in man1.py
foo called module1 from manModules: module1 in manModules 

As a suggestion, maybe re-think the purpose of those SoftLib files. Is it some sort of "bridge" between man1.py and man1test.py? The way your files are setup right now, I don't think it's going to work as you expect it to be. Also, it's a bit confusing for the code-under-test (man1.py) to be importing stuff from under the test folder (MansTest).

Why does it work in Chrome and not Firefox?

The W3 spec for CORS preflight requests clearly states that user credentials should be excluded. There is a bug in Chrome and WebKit where OPTIONS requests returning a status of 401 still send the subsequent request.

Firefox has a related bug filed that ends with a link to the W3 public webapps mailing list asking for the CORS spec to be changed to allow authentication headers to be sent on the OPTIONS request at the benefit of IIS users. Basically, they are waiting for those servers to be obsoleted.

How can I get the OPTIONS request to send and respond consistently?

Simply have the server (API in this example) respond to OPTIONS requests without requiring authentication.

Kinvey did a good job expanding on this while also linking to an issue of the Twitter API outlining the catch-22 problem of this exact scenario interestingly a couple weeks before any of the browser issues were filed.

The search path that the loader uses when you call LoadLibrary() can be altered by using the SetDllDirectory() function. So you could just call this and add the path to your dependency before you load it.

See also DLL Search Order.

If you're using .NET Core, you will have to .AllowCredentials() when configuring CORS in Startup.CS.

Inside of ConfigureServices

services.AddCors(o => {
    o.AddPolicy("AllowSetOrigins", options =>
    {
        options.WithOrigins("https://localhost:xxxx");
        options.AllowAnyHeader();
        options.AllowAnyMethod();
        options.AllowCredentials();
    });
});

services.AddMvc();

Then inside of Configure:

app.UseCors("AllowSetOrigins");
app.UseMvc(routes =>
    {
        // Routing code here
    });

For me, it was specifically just missing options.AllowCredentials() that caused the error you mentioned. As a side note in general for others having CORS issues as well, the order matters and AddCors() must be registered before AddMVC() inside of your Startup class.

Have a look at this article, it's not an exact match to your problem, but suits it:

• Craig Murphy - Excel – wordwrap row autosize issue

In C++ NULL expands to 0 or 0L. See this quote from Stroustrup's FAQ:

Should I use NULL or 0?

In C++, the definition of NULL is 0, so there is only an aesthetic difference. I prefer to avoid macros, so I use 0. Another problem with NULL is that people sometimes mistakenly believe that it is different from 0 and/or not an integer. In pre-standard code, NULL was/is sometimes defined to something unsuitable and therefore had/has to be avoided. That's less common these days.

If you have to name the null pointer, call it nullptr; that's what it's called in C++11. Then, "nullptr" will be a keyword.

Look at the traceback:

Traceback (most recent call last):
  File "C:\Python33\lib\site-packages\bottle.py", line 821, in _cast
    out = iter(out)
TypeError: 'bool' object is not iterable

Your code isn't iterating the value, but the code receiving it is.

The solution is: return an iterable. I suggest that you either convert the bool to a string (str(False)) or enclose it in a tuple ((False,)).

Always read the traceback: it's correct, and it's helpful.

After upgrading Spring boot to the latest version - 2.3.3.RELEASE. I also got this error - Cannot resolve org.springframework.boot:spring-boot-starter-test:unknown. Maven clean install, updating maven project, cleaning cache do not help.
The solution was adding version placeholder from spring boot parent pom:

 <dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-test</artifactId>
   <version>${spring-boot.version}</version>
   <scope>test</scope>
 </dependency>

ALTER TABLE allitems
CHANGE itemid itemid INT(10) AUTO_INCREMENT;

Another solution, using JQUERY, would be to write a function that is invoked when the user clicks the button. This function creates a new <A> element, with target='blank', appends this to the document, 'clicks' it then removes it.

So as far as the user is concerned, they clicked a button, but behind the scenes, an <A> element with target='_blank' was clicked.

<input type="button" id='myButton' value="facebook">

$(document).on('ready', function(){
     $('#myButton').on('click',function(){
         var link = document.createElement("a");
         link.href = 'http://www.facebook.com/';
         link.style = "visibility:hidden";
         link.target = "_blank";
         document.body.appendChild(link);
         link.click();
         document.body.removeChild(link); 
     });
});

What you are using is called a list comprehension in Python, not an inline for-loop (even though it is similar to one). You would write your loop as a list comprehension like so:

p = [q.index(v) if v in q else 99999 for v in vm]

When using a list comprehension, you do not call list.append because the list is being constructed from the comprehension itself. Each item in the list will be what is returned by the expression on the left of the for keyword, which in this case is q.index(v) if v in q else 99999. Incidentially, if you do use list.append inside a comprehension, then you will get a list of None values because that is what the append method always returns.

Follow the steps mentioned for using support ActionBar in Android Studio(0.4.2) :

Download the Android Support Repository from Android SDK Manager, SDK Manager icon will be available on Android Studio tool bar (or Tools -> Android -> SDK Manager).

After download you will find your Support repository here

$SDK_DIR\extras\android\m2repository\com\android\support\appcompat-v7

Open your main module's build.gradle file and add following dependency for using action bar in lower API level

dependencies {
    compile 'com.android.support:appcompat-v7:+'
}

Sync your project with gradle using the tiny Gradle icon available in toolbar (or Tools -> Android -> Sync Project With Gradle Files).

There is some issue going on with Android Studio 0.4.2 so check this as well if you face any issue while importing classes in code.

Import Google Play Services library in Android Studio

If Required follow the steps as well :

• Exit Android Studio
• Delete all the .iml files and files inside .idea folder from your project
• Relaunch Android Studio and wait till the project synced completely with gradle. If it shows an error in Event Log with import option click on Import Project.

This is bug in Android Studio 0.4.2 and fixed for Android Studio 0.4.3 release.

while(something.hasnext())
do something...
   if(contains something to process){
      do something...
      break;
   }
}

Just use the break statement;

For eg:this just prints "Breaking..."

while (true) {
     if (true) {
         System.out.println("Breaking...");
         break;
     }
     System.out.println("Did this print?");
}

The geocoder has quota and rate limits. From experience, you can geocode ~10 locations without hitting the query limit (the actual number probably depends on server loading). The best solution is to delay when you get OVER_QUERY_LIMIT errors, then retry. See these similar posts:

• OVER_QUERY_LIMIT in Google Maps API v3: How do I pause/delay in Javascript to slow it down?

• How do I Geocode 20 addresses without receiving an OVER_QUERY_LIMIT response?

Based on Kapitán Mlíko's answer with source above, I would change it to use the following:

It's a better practice to use the Marlett font rather than Path Data points for the Minimize, Restore/Maximize and Close buttons.

If you need to do it with a set number of columns, H.B.'s way is best. But if you don't know how many columns you are dealing with until runtime, then the below code [read: hack] will work. I am not sure if there is a better solution with an unknown number of columns. It took me two days working at it off and on to get it, so I'm sticking with it regardless.

C#

public class ValueToBrushConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        int input;
        try
        {
            DataGridCell dgc = (DataGridCell)value;
            System.Data.DataRowView rowView = (System.Data.DataRowView)dgc.DataContext;
            input = (int)rowView.Row.ItemArray[dgc.Column.DisplayIndex];
        }
        catch (InvalidCastException e)
        {
            return DependencyProperty.UnsetValue;
        }
        switch (input)
        {
            case 1: return Brushes.Red;
            case 2: return Brushes.White;
            case 3: return Brushes.Blue;
            default: return DependencyProperty.UnsetValue;
        }
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        throw new NotSupportedException();
    }
}

XAML

<UserControl.Resources>
    <conv:ValueToBrushConverter x:Key="ValueToBrushConverter"/>
    <Style x:Key="CellStyle" TargetType="DataGridCell">
        <Setter Property="Background" Value="{Binding RelativeSource={RelativeSource Self}, Converter={StaticResource ValueToBrushConverter}}" />
    </Style>
</UserControl.Resources>
<DataGrid x:Name="dataGrid" CellStyle="{StaticResource CellStyle}">
</DataGrid>

Worked for me:

1. Download package (see links below), name it lp.cab and place it to your C: drive

2. Run the following commands as Administrator:

2.1 installing new language

dism /Online /Add-Package /PackagePath:C:\lp.cab

2.2 get installed packages

dism /Online /Get-Packages

2.3 remove original package

dism /Online /Remove-Package /PackageName:Microsoft-Windows-Client-LanguagePack-Package~31bf3856ad364e35~amd64~ru-RU~10.0.10240.16384

If you don't know which is your original package you can check your installed packages with this line

dism /Online /Get-Packages | findstr /c:"LanguagePack"

3. Enjoy your new system language

I don't think anything like that is built-in in Ruby. You can reopen String class and add to_bool method there:

class String
    def to_bool
        return true if self=="true"
        return false if self=="false"
        return nil
    end
end

Then you can use it anywhere in your project, like this: params[:internal].to_bool

Yes. In Ruby the not equal to operator is:

!=

You can get a full list of ruby operators here: https://www.tutorialspoint.com/ruby/ruby_operators.htm.

Very easy if you are already using a statelessWidget checkOut my code

class _MyThirdPage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Understanding Material-Cards'),
      ),
      body: SingleChildScrollView(
          child: Column(
        children: <Widget>[
          _buildStack(),
          _buildCard(),
          SingleCard(),
          _inkwellCard()
        ],
      )),
    );
  }
}

You can do quite a lot with plain css...the css property background-size can be set to a number of things as well as just cover as Ranjith pointed out.

The background-size: cover setting scales the image to cover the entire screen but may mean that some of the image is off screen if the aspect ratio of the screen and image are different.

A good alternative is background-size: contain which resizes the background image to fit the smaller of width and height, ensuring that the whole image is visible but may lead to letterboxing if the aspect ratios are different.

For example:

body {
      background: url(/images/bkgd.png) no-repeat rgb(30,30,30) fixed center center;
      background-size: contain;
     }

The other options that I find less useful are: background-size: length <widthpx> <heightpx> which sets the absolute size of the background image. background-size: percentage <width> <height> background image is a percentage of the window size. (see w3schools.com's page)

In Visual Studio 2012
Go to
Edit -> Advanced -> View White Spaces
Or
Press Ctrl+R, Ctrl+W

You can do it with Intl.NumberFormat native API.

var number = 123456.78;_x000D_
_x000D_
// India uses thousands/lakh/crore separators_x000D_
console.log(new Intl.NumberFormat('en-IN', {_x000D_
  style: 'currency',_x000D_
  currency: 'INR'_x000D_
}).format(number));

Don't do nl2br when you save it to the database. Do nl2br when you're displaying the text in HTML. I can strongly recommend to not store any HTML formatting in the database (unless you're using a rich HTML editor as well, in which case it would be silly not to).

A newline \n will just become a newline in the textarea.

this may be also possibly solution.It some times also occurs when you keep your Development project into too deep, means may be possible project directory may have too many directories so please don't make too many directories keep it in a simple folder inside the drives. For Example- I was also getting this error when my project was kept like this-

D:\Sharad\LatestWorkings\GenericSurveyApplication020120\GenericSurveyApplication\GenericSurveyApplication

then I simply Pasted my project inside

D:\Sharad\LatestWorkings\GenericSurveyApplication

And Problem was solved.

    startActivity(pdfIntent ); 
    }
catch (ActivityNotFoundException e) {

    $params   = $_SERVER['QUERY_STRING'];

    return $protocol . '://' . $host . $script . '?' . $params;

Then add your value with something like;

echo currentUrl().'&value=myVal';

It causes the error when you access $(this).val() when it called by change event this points to the invoker i.e. CourseSelect so it is working and and will get the value of CourseSelect. but when you manually call it this points to document. so either you will have to pass the CourseSelect object or access directly like $("#CourseSelect").val() instead of $(this).val().

If multiple characters are bound inside a single integer/long, as was my issue:

s = '0123456789'
nchars = len(s)
# string to int or long. Type depends on nchars
x = sum(ord(s[byte])<<8*(nchars-byte-1) for byte in range(nchars))
# int or long to string
''.join(chr((x>>8*(nchars-byte-1))&0xFF) for byte in range(nchars))

Yields '0123456789' and x = 227581098929683594426425L

100000 + Math.floor(Math.random() * 900000);

will give a number from 100000 to 999999 (inclusive).

I needed to load the settings file synchronously, and this was my solution:

export function InitConfig(config: AppConfig) { return () => config.load(); }

import { Injectable } from '@angular/core';

@Injectable()
export class AppConfig {
    Settings: ISettings;

    constructor() { }

    load() {
        return new Promise((resolve) => {
            this.Settings = this.httpGet('assets/clientsettings.json');
            resolve(true);
        });
    }

    httpGet(theUrl): ISettings {
        const xmlHttp = new XMLHttpRequest();
        xmlHttp.open( 'GET', theUrl, false ); // false for synchronous request
        xmlHttp.send( null );
        return JSON.parse(xmlHttp.responseText);
    }
}

This is then provided as a app_initializer which is loaded before the rest of the application.

app.module.ts

{
      provide: APP_INITIALIZER,
      useFactory: InitConfig,
      deps: [AppConfig],
      multi: true
    },

For macOS and Windows

Docker v 18.03 and above (since March 21st 2018)

Use your internal IP address or connect to the special DNS name host.docker.internal which will resolve to the internal IP address used by the host.

Linux support pending https://github.com/docker/for-linux/issues/264

MacOS with earlier versions of Docker

Docker for Mac v 17.12 to v 18.02

Same as above but use docker.for.mac.host.internal instead.

Docker for Mac v 17.06 to v 17.11

Same as above but use docker.for.mac.localhost instead.

Docker for Mac 17.05 and below

To access host machine from the docker container you must attach an IP alias to your network interface. You can bind whichever IP you want, just make sure you're not using it to anything else.

sudo ifconfig lo0 alias 123.123.123.123/24

Then make sure that you server is listening to the IP mentioned above or 0.0.0.0. If it's listening on localhost 127.0.0.1 it will not accept the connection.

Then just point your docker container to this IP and you can access the host machine!

To test you can run something like curl -X GET 123.123.123.123:3000 inside the container.

The alias will reset on every reboot so create a start-up script if necessary.

Solution and more documentation here: https://docs.docker.com/docker-for-mac/networking/#use-cases-and-workarounds

hive> show partitions table_name;

Try

    $(document).ready(function () {
        if ($("#site").length > 0) {
            window.location = "<%= Url.Content("~") %>" + "Login/LogOn";
        }
    });

Put it on the login page. If it was loaded in a div on the main page, it will redirect til the login page. "#site" is a id of a div which is located on all pages except login page.

To get a better understanding on it, one must see the architecture of Selenium WebDriver.

Just visit https://github.com/SeleniumHQ/selenium/wiki/JsonWireProtocol

and search for "Navigate to a new URL." text. You will see both methods GET and POST.

Hence the conclusion given below:

driver.get() method internally sends Get request to Selenium Server Standalone. Whereas driver.navigate() method sends Post request to Selenium Server Standalone.

Hope it helps

All work perfectly :)

 NSString *test = @"test";
 unichar a;
 int index = 5;
    
 @try {
    a = [test characterAtIndex:index];

    NSLog(@"Char at index %d cannot be found", index);
    NSLog(@"Max index is: %lu", [test length] - 1);
 }
 @finally {
    NSLog(@"Finally condition");
 }

Log:

[__NSCFConstantString characterAtIndex:]: Range or index out of bounds

Char at index 5 cannot be found

Max index is: 3

Finally condition

Nowadays, you should use ERB::Util.url_encode or CGI.escape. The primary difference between them is their handling of spaces:

>> ERB::Util.url_encode("foo/bar? baz&")
=> "foo%2Fbar%3F%20baz%26"

>> CGI.escape("foo/bar? baz&")
=> "foo%2Fbar%3F+baz%26"

CGI.escape follows the CGI/HTML forms spec and gives you an application/x-www-form-urlencoded string, which requires spaces be escaped to +, whereas ERB::Util.url_encode follows RFC 3986, which requires them to be encoded as %20.

See "What's the difference between URI.escape and CGI.escape?" for more discussion.

I have tried many solutions, but the one that worked for is the following:

There is no need to edit the info.plist in ios 8 and 9.

- (BOOL) shouldAutorotate {
    return NO;
}   

- (UIInterfaceOrientationMask)supportedInterfaceOrientations {
    return (UIInterfaceOrientationPortrait | UIInterfaceOrientationPortraitUpsideDown);
}

Possible orientations from the Apple Documentation:

UIInterfaceOrientationUnknown

The orientation of the device cannot be determined.

UIInterfaceOrientationPortrait

The device is in portrait mode, with the device held upright and the home button on the bottom.

UIInterfaceOrientationPortraitUpsideDown

The device is in portrait mode but upside down, with the device held upright and the home button at the top.

UIInterfaceOrientationLandscapeLeft

The device is in landscape mode, with the device held upright and the home button on the left side.

UIInterfaceOrientationLandscapeRight

The device is in landscape mode, with the device held upright and the home button on the right side.

Running

git remote set-head origin --auto

followed by

git gc

An alternative solution inspired by the accepted response, but that uses an inverted logic:

MODE="${1}"

echo "<${MODE}>"
[[ "${MODE}" =~ ^(preview|live|both)$ ]] && echo "OK" || echo "Uh?"

Here, the input ($MODE) must be one of the options in the regular expression ('preview', 'live', or 'both'), contrary to matching the whole options list to the user input. Of course, you do not expect the regular expression to change.

It's always good to show a complete working code snippet:

// in viewDidLoad (if using Autolayout check note below):

UIScrollView *myScrollView;
UIView *contentView;
// scrollview won't scroll unless content size explicitly set

[myScrollView addSubview:contentView];//if the contentView is not already inside your scrollview in your xib/StoryBoard doc

myScrollView.contentSize = contentView.frame.size; //sets ScrollView content size

Swift 4.0

let myScrollView
let contentView

// scrollview won't scroll unless content size explicitly set

myScrollView.addSubview(contentView)//if the contentView is not already inside your scrollview in your xib/StoryBoard doc

myScrollView.contentSize = contentView.frame.size //sets ScrollView content size

I have not found a way to set contentSize in IB (as of Xcode 5.0).

Note: If you are using Autolayout the best place to put this code is inside the -(void)viewDidLayoutSubviews method .

var trLength = jQuery('#tablebodyID >tr').length;

My lightweight implementation of ParallelForEach async.

Features:

1. Throttling (max degree of parallelism).
2. Exception handling (aggregation exception will be thrown at completion).
3. Memory efficient (no need to store the list of tasks).

public static class AsyncEx
{
    public static async Task ParallelForEachAsync<T>(this IEnumerable<T> source, Func<T, Task> asyncAction, int maxDegreeOfParallelism = 10)
    {
        var semaphoreSlim = new SemaphoreSlim(maxDegreeOfParallelism);
        var tcs = new TaskCompletionSource<object>();
        var exceptions = new ConcurrentBag<Exception>();
        bool addingCompleted = false;

        foreach (T item in source)
        {
            await semaphoreSlim.WaitAsync();
            asyncAction(item).ContinueWith(t =>
            {
                semaphoreSlim.Release();

                if (t.Exception != null)
                {
                    exceptions.Add(t.Exception);
                }

                if (Volatile.Read(ref addingCompleted) && semaphoreSlim.CurrentCount == maxDegreeOfParallelism)
                {
                    tcs.TrySetResult(null);
                }
            });
        }

        Volatile.Write(ref addingCompleted, true);
        await tcs.Task;
        if (exceptions.Count > 0)
        {
            throw new AggregateException(exceptions);
        }
    }
}

Usage example:

await Enumerable.Range(1, 10000).ParallelForEachAsync(async (i) =>
{
    var data = await GetData(i);
}, maxDegreeOfParallelism: 100);

First give your form an id attribute, then use code like this:

$(document).ready( function() {
  var form = $('#my_awesome_form');

  form.find('select:first').change( function() {
    $.ajax( {
      type: "POST",
      url: form.attr( 'action' ),
      data: form.serialize(),
      success: function( response ) {
        console.log( response );
      }
    } );
  } );

} );

So this code uses .serialize() to pull out the relevant data from the form. It also assumes the select you care about is the first one in the form.

For future reference, the jQuery docs are very, very good.

I was looking for an example that had default kwargs using type annotation:

def test_var_kwarg(a: str, b: str='B', c: str='', **kwargs) -> str:
     return ' '.join([a, b, c, str(kwargs)])

example:

>>> print(test_var_kwarg('A', c='okay'))
A B okay {}
>>> d = {'f': 'F', 'g': 'G'}
>>> print(test_var_kwarg('a', c='c', b='b', **d))
a b c {'f': 'F', 'g': 'G'}
>>> print(test_var_kwarg('a', 'b', 'c'))
a b c {}

Updated answer for Django migrations without south plugin:

Like T.T suggested in his answer, my previous answer was for south migration plugin, when Django hasn't any schema migration features. Now (works in Django 1.9+):

T.T wrote:

You can try this!

python manage.py makemigrations

python manage.py migrate --run-syncdb

Outdated for south migrations plugin

As I can see you done it all in wrong order, to fix it up your should complete this checklist (I assume you can't delete sqlite3 database file to start over):

1. Grab any SQLite GUI tool (i.e. http://sqliteadmin.orbmu2k.de/)
2. Change your model definition to match database definition (best approach is to comment new fields)
3. Delete migrations folder in your model
4. Delete rows in south_migrationhistory table where app_name match your application name (probably homework)
5. Invoke: ./manage.py schemamigration <app_name> --initial
6. Create tables by ./manage.py migrate <app_name> --fake (--fake will skip SQL execute because table already exists in your database)
7. Make changes to your app's model
8. Invoke ./manage.py schemamigration <app_name> --auto
9. Then apply changes to database: ./manage.py migrate <app_name>

Steps 7,8,9 repeat whenever your model needs any changes.

Missing ; after var_dump($row)

in ViewGroup you can add some other Views as child. ViewGroup is the base class for layouts and view containers.

Notice that your error message only contains five K, V pairs, 10 arguments total. This is by design; the ImmutableMap class provides six different of() methods, accepting between zero and five key-value pairings. There is not an of(...) overload accepting a varags parameter because K and V can be different types.

You want an ImmutableMap.Builder:

ImmutableMap<String,String> myMap = ImmutableMap.<String, String>builder()
    .put("key1", "value1") 
    .put("key2", "value2") 
    .put("key3", "value3") 
    .put("key4", "value4") 
    .put("key5", "value5") 
    .put("key6", "value6") 
    .put("key7", "value7") 
    .put("key8", "value8") 
    .put("key9", "value9")
    .build();

Section 6.5.8.6 of the C standard says:

Each of the operators < (less than), > (greater than), <= (less than or equal to), and >= (greater than or equal to) shall yield 1 if the specified relation is true and 0 if it is false.) The result has type int.

You start a thread which runs the static method SumData. However, SumData calls SetTextboxText which isn't static. Thus you need an instance of your form to call SetTextboxText.

Another option is to mirror the S3 bucket on your web server and traverse locally. The trick is that the local files are empty and only used as a skeleton. Alternatively, the local files could hold useful meta data that you normally would need to get from S3 (e.g. filesize, mimetype, author, timestamp, uuid). When you provide a URL to download the file, search locally and but provide a link to the S3 address.

Local file traversing is easy and this approach for S3 management is language agnostic. Local file traversing also avoids maintaining and querying a database of files or delays making a series of remote API calls to authenticate and get the bucket contents.

You could allow users to upload files directly to your server via FTP or HTTP and then transfer a batch of new and updated files to Amazon at off peak times by just recursing over the directories for files with any size. On the completion of a file transfer to Amazon, replace the web server file with an empty one of the same name. If a local file has any filesize then serve it directly because its awaiting batch transfer.

Here's what I do:

Generate a hidden iFrame with the data you would like to post. Since you still control that iFrame, same origin does not apply. Then submit the form in that iFrame to the ssl page. The ssl page then redirects to a non-ssl page with status messages. You have access to the iFrame.

Dictionary<String,String> d = new Dictionary<String,String>();
        d.Add("1","Mahadev");
        d.Add("2","Mahesh");
        Console.WriteLine(d["1"]);// it will print Value of key '1'

To change image by using code

public void onClick(View v) {
   if(v == ButtonName) {
     ButtonName.setImageResource(R.drawable.ImageName);
   }
}

Or, using an XML file:

<?xml version="1.0" encoding="utf-8"?> 
<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:state_pressed="true"
   android:drawable="@drawable/login_selected" /> <!-- pressed -->
  <item android:state_focused="true"
   android:drawable="@drawable/login_mouse_over" /> <!-- focused -->
  <item android:drawable="@drawable/login" /> <!-- default -->
</selector>

In OnClick, just add this code:

ButtonName.setBackgroundDrawable(getResources().getDrawable(R.drawable.ImageName));

You can do it by lodash _.head so easily.

var arr = ['first', 'second', 'third', 'fourth', 'fifth'];_x000D_
console.log(_.head(arr));

<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.11/lodash.min.js"></script>

Check if you have a android-support-v4.jar file in YOUR project's lib folder, it should be removed!

In the tutorial, when you have followed the instructions of Adding libraries WITHOUT resources before doing the coorect Adding libraries WITH resources you'll get the same error.

(Don't know why someone would do something like that *lookingawayfrommyself* ^^)

So what did fix it in my case, was removing the android-support-v4.jar from YOUR PROJECT (not the android-support-v7-appcompat project), since this caused some kind of library collision (maybe because in the meantime there was a new version of the suport library).

Just another case, when this error might shows up.

You need to instantiate the other classes inside the main class;

Date d = new Date(params);
TemperatureRange t = new TemperatureRange(params);

You can then call their methods with:

object.methodname(params);
d.method();

You currently have constructors in your other classes. You should not return anything in these.

public Date(params){
    set variables for date object
}

Next you need a method to reference.

public returnType methodName(params){
  return something;
}

You get that message because you made changes in your local master and you didn't push them to remote. You have several ways to "solve" it and it normally depends on how your workflow looks like:

• In a good workflow your remote copy of master should be the good one while your local copy of master is just a copy of the one in remote. Using this workflow you'll never get this message again.
• If you work in another way and your local changes should be pushed then just git push origin assuming origin is your remote
• If your local changes are bad then just remove them or reset your local master to the state on remote git reset --hard origin/master

A loose analogy is, "Meteor is to Node as Rails is to Ruby." It's a large, opinionated framework that uses Node on the server. Node itself is just a low-level framework providing functions for sending and receiving HTTP requests and performing other I/O.

Meteor is radically ambitious: By default, every page it serves is actually a Handlebars template that's kept in sync with the server. Try the Leaderboard example: You create a template that simply says "List the names and scores," and every time any client changes a name or score, the page updates with the new data—not just for that client, but for everyone viewing the page.

Another difference: While Node itself is stable and widely used in production, Meteor is in a "preview" state. There are serious bugs, and certain things that don't fit with Meteor's data-centric conceptual model (such as animations) are very hard to do.

If you love playing with new technologies, give Meteor a spin. If you want a more traditional, stable web framework built on Node, take a look at Express.

If anyone wants a free and effective option (and don't mind doing it manually) to backup database to Local then use schema and data comparison functionality built into the latest version Microsoft Visual Studio 2015 Community Edition (Free) or Professional / Premium / Ultimate edition. It works like a charm!

I have BizPark account with Azure and there is no way to backup database directly without paying. I found this option in VS works.

Answer is taken from https://stackoverflow.com/a/685073/6796187

$vid = preg_replace('/^.*(\?|\&)v\=/', '', $url);  // Strip all meuk before and including '?v=' or '&v='.

$vid = preg_replace('/[^\w\-\_].*$/', '', $vid);  // Strip trailing meuk.

Integer is wrapper class and int is primitive data type.Always prefer using Integer in ArrayList.

This is how I do it.

    import os
    for x in os.listdir(os.getcwd()):
        if os.path.isdir(x):
            print(x)

Evaluating "1,2,3" results in (1, 2, 3), a tuple. As you've discovered, tuples are immutable. Convert to a list before processing.

You can use putStringSet

This allow you to save a HashSet in your preferences, just like this:

Save

Set<String> values;

SharedPreferences sharedPref = 
    mContext.getSharedPreferences(PREF_KEY, Context.MODE_PRIVATE);

Editor editor = sharedPref.edit();

editor.putStringSet("YOUR_KEY", values);
editor.apply();

Retrive

SharedPreferences sharedPref = 
    mContext.getSharedPreferences(PREF_KEY, Context.MODE_PRIVATE);

Editor editor = sharedPref.edit();

Set<String> newList = editor.getStringSet("YOUR_KEY", null);

The putStringSet allow just a Set and this is an unordered list.

@JsonSerialize and @JsonDeserialize worked fine for me. They eliminate the need to import the additional jsr310 module:

@JsonDeserialize(using = LocalDateDeserializer.class)  
@JsonSerialize(using = LocalDateSerializer.class)  
private LocalDate dateOfBirth;

Deserializer:

public class LocalDateDeserializer extends StdDeserializer<LocalDate> {

    private static final long serialVersionUID = 1L;

    protected LocalDateDeserializer() {
        super(LocalDate.class);
    }


    @Override
    public LocalDate deserialize(JsonParser jp, DeserializationContext ctxt)
            throws IOException, JsonProcessingException {
        return LocalDate.parse(jp.readValueAs(String.class));
    }

}

Serializer:

public class LocalDateSerializer extends StdSerializer<LocalDate> {

    private static final long serialVersionUID = 1L;

    public LocalDateSerializer(){
        super(LocalDate.class);
    }

    @Override
    public void serialize(LocalDate value, JsonGenerator gen, SerializerProvider sp) throws IOException, JsonProcessingException {
        gen.writeString(value.format(DateTimeFormatter.ISO_LOCAL_DATE));
    }
}

As posted in my update above, a potential solution would be to use Declaration Merging as suggested by @Tyler-sebastion. I was able to define two additional interfaces and add the index property on the EventTarget in this way.

interface KonvaTextEventTarget extends EventTarget {
  index: number
}

interface KonvaMouseEvent extends React.MouseEvent<HTMLElement> {
  target: KonvaTextEventTarget
}

I then can declare the event as KonvaMouseEvent in my onclick MouseEventHandler function.

onClick={(event: KonvaMouseEvent) => {
          makeMove(ownMark, event.target.index)
}}

I'm still not 100% if this is the best approach as it feels a bit Kludgy and overly verbose just to get past the tslint error.

With argparse you could do:

parser.argparse.ArgumentParser()
#parser.add_args here

#sys.argv includes a list of elements starting with the program
if len(sys.argv) < 2:
    parser.print_usage()
    sys.exit(1)

you need to decode the bytes of you want a string:

b = b'1234'
print(b.decode('utf-8'))  # '1234'

Use org.apache.commons.lang3.StringUtils

String emptyString = new String();    
result = StringUtils.defaultIfEmpty(emptyString, "default");
System.out.println(result);

String nullString = null;
result = StringUtils.defaultIfEmpty(nullString, "default");
System.out.println(result);

Both of the above options will print:

default

default

Have you looked at python-graph? I haven't used it myself, but the project page looks promising.

My solution is based on the TechNet article Fun Things You Can Do With the Get-ChildItem Cmdlet.

Get-ChildItem C:\foo | Where-Object {$_.mode -match "d"}

I used it in my script, and it works well.

You can try the following one-statement:

if (($x-$min)*($x-$max) < 0)

or:

if (max(min($x, $max), $min) == $x)

Cast one of the integers/both of the integer to float to force the operation to be done with floating point Math. Otherwise integer Math is always preferred. So:

1. v = (float)s / t;
2. v = (float)s / (float)t;

If you are sure that all the modules, files you're trying to import are in the same folder and they should be picked directly just by giving the name and not the reference path then your editor or terminal should have opened the main folder where all the files/modules are present.

Either, try running from Terminal, make sure first you go to the correct directory.

cd path to the root folder where all the modules are

python script.py

Or if running [F5] from the editor i.e VsCode then open the complete folder there and not the individual files.

Markdown gets converted into HTML/XHMTL.

John Gruber created the Markdown language in 2004 in collaboration with Aaron Swartz on the syntax, with the goal of enabling people to write using an easy-to-read, easy-to-write plain text format, and optionally convert it to structurally valid HTML (or XHTML).

HTML is completely based on using   for adding extra spaces if it doesn't externally define/use JavaScript or CSS for elements.

Markdown is a lightweight markup language with plain text formatting syntax. It is designed so that it can be converted to HTML and many other formats using a tool by the same name.

If you want to use »

1. only one space » either use   or just hit Spacebar (2nd one is good choice in this case)

2. more than one space » use  +space (for 2 consecutive spaces)

eg. If you want to add 10 spaces contiguously then you should use

                   

 space space space space space

instead of using 10   one after one as the below one

          

For more details check

1. Adding multiple spaces between text in Markdown,
2. How to create extra space in HTML or web page.

For those not getting a solution for older answers, i simply put my file name as the very first line in my code.

like so

 #ruby_file_name_here.rb

 puts "hello world"

The SKU example used in the documentation was to provide the allowed characters in a new user-specified SKU.

Yes, it will work fine as you have synchronized the list . I would suggest you to use CopyOnWriteArrayList.

CopyOnWriteArrayList<String> cpList=new CopyOnWriteArrayList<String>(new ArrayList<String>());

    void remove(String item)
    {
         do something; (doesn't work on the list)
                 cpList..remove(item);
    }

Edit: You didn't say you had pushed to a public repo! That makes a world of difference.

There are two ways, the "dirty" way and the "clean" way. Suppose your branch is named new-master. This is the clean way:

git checkout new-master
git branch -m master old-master
git branch -m new-master master
# And don't do this part.  Just don't.  But if you want to...
# git branch -d --force old-master

This will make the config files change to match the renamed branches.

You can also do it the dirty way, which won't update the config files. This is kind of what goes on under the hood of the above...

mv -i .git/refs/new-master .git/refs/master
git checkout master

Follow the simplest (in my opinion) way to modify objects from another thread:

using System.Threading.Tasks;
using System.Threading;

namespace TESTE
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            Action<string> DelegateTeste_ModifyText = THREAD_MOD;
            Invoke(DelegateTeste_ModifyText, "MODIFY BY THREAD");
        }

        private void THREAD_MOD(string teste)
        {
            textBox1.Text = teste;
        }
    }
}

In addition to the answer of Dyppl, I think it would be nice to place this inside the OnDataContextChanged event:

private void OnDataContextChanged(object sender, DependencyPropertyChangedEventArgs e)
{
    // Unforunately we cannot bind from the viewmodel to the code behind so easily, the dependency property is not available in XAML. (for some reason).
    // To work around this, we create the binding once we get the viewmodel through the datacontext.
    var newViewModel = e.NewValue as MyViewModel;

    var executablePathBinding = new Binding
    {
        Source = newViewModel,
        Path = new PropertyPath(nameof(newViewModel.ExecutablePath))
    };

    BindingOperations.SetBinding(LayoutRoot, ExecutablePathProperty, executablePathBinding);
}

We have also had cases were we just saved the DataContext to a local property and used that to access viewmodel properties. The choice is of course yours, I like this approach because it is more consistent with the rest. You can also add some validation, like null checks. If you actually change your DataContext around, I think it would be nice to also call:

BindingOperations.ClearBinding(myText, TextBlock.TextProperty);

to clear the binding of the old viewmodel (e.oldValue in the event handler).

<head>
<script>
    function myFunction() {
        var x;
        var r = confirm("Do you want to clear data?");
        if (r == true) {
            x = "Your Data is Cleared";
            window.location.href = "firstpage.php";
        }
        else {
            x = "You pressed Cancel!";
        }
        document.getElementById("demo").innerHTML = x;
    }
</script>
</head>
<body>
<button onclick="myFunction()">Retest</button>

<p id="demo"></p>
</body>
</html>

This will redirect to new php page.

Just type the code and save it in .cpp format. then try "gcc filename.cpp" . This will create the object file. then try "./a.out" (This is the default object file name). If you want to know about gcc you can always try "man gcc"

But watch out, on most xampp/ampp/...-setups and some linux destributions it's 0, which means the file will never get deleted until you do it within your script (or dirty via shell)

If you're using lodash and in the mood for a too-cute-for-its-own-good one-liner:

_.map(_.words('123, 124, 234,252'), _.add.bind(1, 1));

It's surprisingly robust thanks to lodash's powerful parsing capabilities.

If you want one that will also clean non-digit characters out of the string (and is easier to follow...and not quite so cutesy):

_.chain('123, 124, 234,252, n301')
   .replace(/[^\d,]/g, '')
   .words()
   .map(_.partial(_.add, 1))
   .value();

2017 edit:

I no longer recommend my previous solution. Besides being overkill and already easy to do without a third-party library, it makes use of _.chain, which has a variety of issues. Here's the solution I would now recommend:

const str = '123, 124, 234,252';
const arr = str.split(',').map(n => parseInt(n, 10) + 1);

My old answer is still correct, so I'll leave it for the record, but there's no need to use it nowadays.

I recommend you start reading the documentation (4.6.18. Formatting cells). When applying a lot of formatting it's better to use applyFromArray() According to the documentation this method is also suppose to be faster when you're setting many style properties. There's an annex where you can find all the possible keys for this function.

This will work for you:

$phpExcel = new PHPExcel();

$styleArray = array(
    'font'  => array(
        'bold'  => true,
        'color' => array('rgb' => 'FF0000'),
        'size'  => 15,
        'name'  => 'Verdana'
    ));

$phpExcel->getActiveSheet()->getCell('A1')->setValue('Some text');
$phpExcel->getActiveSheet()->getStyle('A1')->applyFromArray($styleArray);

To apply font style to complete excel document:

 $styleArray = array(
   'font'  => array(
        'bold'  => true,
        'color' => array('rgb' => 'FF0000'),
        'size'  => 15,
        'name'  => 'Verdana'
    ));      
 $phpExcel->getDefaultStyle()
    ->applyFromArray($styleArray);

Just use inline if operation with tuple function:

query = "Select * from hr_employee WHERE id in " % tuple(employee_ids) if len(employee_ids) != 1 else "("+ str(employee_ids[0]) + ")"

// Adds and removes body class depending on screen width.
function screenClass() {
    if($(window).innerWidth() > 960) {
        $('body').addClass('big-screen').removeClass('small-screen');
    } else {
        $('body').addClass('small-screen').removeClass('big-screen');
    }
}

// Fire.
screenClass();

// And recheck when window gets resized.
$(window).bind('resize',function(){
    screenClass();
});

Performance wise there is no difference. The only purpose of having const_iterator over iterator is to manage the accessesibility of the container on which the respective iterator runs. You can understand it more clearly with an example:

std::vector<int> integers{ 3, 4, 56, 6, 778 };

If we were to read & write the members of a container we will use iterator:

for( std::vector<int>::iterator it = integers.begin() ; it != integers.end() ; ++it )
       {*it = 4;  std::cout << *it << std::endl; }

If we were to only read the members of the container integers you might wanna use const_iterator which doesn't allow to write or modify members of container.

for( std::vector<int>::const_iterator it = integers.begin() ; it != integers.end() ; ++it )
       { cout << *it << endl; }

NOTE: if you try to modify the content using *it in second case you will get an error because its read-only.

$ThatTime ="14:08:10";
if (time() >= strtotime($ThatTime)) {
  echo "ok";
}

A solution using DateTime (that also regards the timezone).

$dateTime = new DateTime($ThatTime);
if ($dateTime->diff(new DateTime)->format('%R') == '+') {
  echo "OK";
}

http://php.net/datetime.diff

Note that if the problem is being caused by appearing scrollbars, putting

body {
  overflow: hidden;
}

in your CSS might be an easy fix (if you don't need the page to scroll).

You can also use NumberUtil.isNumber(String str) from Apache Commons

Great answer by Lee Jarvis, this is just the command e.g; we already have an existing model called User:

rails g scaffold_controller User

My answer is not as asked but It is really simple to find if your system is little endian or big endian?

Code:

#include<stdio.h>

int main()
{
  int a = 1;
  char *b;

  b = (char *)&a;
  if (*b)
    printf("Little Endian\n");
  else
    printf("Big Endian\n");
}

YAML version :

overrides:
  - files: *-tests.js
    rules:
      no-param-reassign: 0

Example of specific rules for mocha tests :

You can also set a specific env for a folder, like this :

overrides:
  - files: test/*-tests.js
    env:
      mocha: true

This configuration will fix error message about describe and it not defined, only for your test folder:

/myproject/test/init-tests.js
6:1 error 'describe' is not defined no-undef
9:3 error 'it' is not defined no-undef

This is an old topic, but in case anyone else is still looking...

I was having trouble after an undock event. An open db connection saved in a global object would error, even after reconnecting to the network. This was due to the TCP connection being forcibly terminated by remote host. (Error -2147467259: TCP Provider: An existing connection was forcibly closed by the remote host.)

However, the error would only show up after the first transaction was attempted. Up to that point, neither Connection.State nor Connection.Version (per solutions above) would reveal any error.

So I wrote the small sub below to force the error - hope it's useful.

Performance testing on my setup (Access 2016, SQL Svr 2008R2) was approx 0.5ms per call.

Function adoIsConnected(adoCn As ADODB.Connection) As Boolean

    '#PURPOSE: Checks whether the supplied db connection is alive and
    '          hasn't had it's TCP connection forcibly closed by remote

    '#RETURNS: True if the supplied db is connected and error-free, 
    '          False otherwise
    '#AUTHOR:  Belladonna

    Dim i As Long
    Dim cmd As New ADODB.Command

    cmd.CommandText = "SELECT 1"
    cmd.ActiveConnection = adoCn

    'Run a simple query, to test the connection
    On Error Resume Next
    i = cmd.Execute.Fields(0)
    On Error GoTo 0

    'Tidy up
    Set cmd = Nothing

    'If i is 1, connection is open
    If i = 1 Then
        adoIsConnected = True
    Else
        adoIsConnected = False
    End If

End Function

If you have it available, I would consider using numpy. It's very fast for these types of operations:

>>> import numpy
>>> numpy.array([1,2,3]) + 2
array([3, 4, 5])

This is assuming your real application is doing mathematical operations (that can be vectorized).

This is how you do a distinct count query. Note that you have to filter out the nulls.

var useranswercount = (from a in tpoll_answer
where user_nbr != null && answer_nbr != null
select user_nbr).Distinct().Count();

If you combine this with into your current grouping code, I think you'll have your solution.

Since you're using Lodash you could use _.map and _.find to make sure major browsers are supported.

In the end I would go with something like:

function mergeById(arr) {_x000D_
  return {_x000D_
    with: function(arr2) {_x000D_
      return _.map(arr, item => {_x000D_
        return _.find(arr2, obj => obj.id === item.id) || item_x000D_
      })_x000D_
    }_x000D_
  }_x000D_
}_x000D_
_x000D_
var result = mergeById([{id:'124',name:'qqq'}, _x000D_
           {id:'589',name:'www'}, _x000D_
           {id:'45',name:'eee'},_x000D_
           {id:'567',name:'rrr'}])_x000D_
    .with([{id:'124',name:'ttt'}, {id:'45',name:'yyy'}])_x000D_
_x000D_
console.log(result);

There are two approaches you can take, to have a hovered element affect (E) another element (F):

1. F is a child-element of E, or
2. F is a later-sibling (or sibling's descendant) element of E (in that E appears in the mark-up/DOM before F):

To illustrate the first of these options (F as a descendant/child of E):

.item:hover .wrapper {
    color: #fff;
    background-color: #000;
}?

To demonstrate the second option, F being a sibling element of E:

.item:hover ~ .wrapper {
    color: #fff;
    background-color: #000;
}?

In this example, if .wrapper was an immediate sibling of .item (with no other elements between the two) you could also use .item:hover + .wrapper.

Why not using Cakes Response Class? You can set the status code of the response simply by this:

$this->response->statusCode(200);

Then just render a file with the error message, which suits best with JSON.

The error Event the onerror handler receives is a simple event not containing such information:

If the user agent was required to fail the WebSocket connection or the WebSocket connection is closed with prejudice, fire a simple event named error at the WebSocket object.

You may have better luck listening for the close event, which is a CloseEvent and indeed has a CloseEvent.code property containing a numerical code according to RFC 6455 11.7 and a CloseEvent.reason string property.

Please note however, that CloseEvent.code (and CloseEvent.reason) are limited in such a way that network probing and other security issues are avoided.

There is no limitation of list number. The main reason which causes your error is the RAM. Please upgrade your memory size.

In Java 8, you can now pass a method more easily using Lambda Expressions and Method References. First, some background: a functional interface is an interface that has one and only one abstract method, although it can contain any number of default methods (new in Java 8) and static methods. A lambda expression can quickly implement the abstract method, without all the unnecessary syntax needed if you don't use a lambda expression.

Without lambda expressions:

obj.aMethod(new AFunctionalInterface() {
    @Override
    public boolean anotherMethod(int i)
    {
        return i == 982
    }
});

With lambda expressions:

obj.aMethod(i -> i == 982);

Here is an excerpt from the Java tutorial on Lambda Expressions:

Syntax of Lambda Expressions

A lambda expression consists of the following:

• A comma-separated list of formal parameters enclosed in parentheses. The CheckPerson.test method contains one parameter, p, which represents an instance of the Person class.
  
  Note: You can omit the data type of the parameters in a lambda expression. In addition, you can omit the parentheses if there is only one parameter. For example, the following lambda expression is also valid:

  p -> p.getGender() == Person.Sex.MALE 
      && p.getAge() >= 18
      && p.getAge() <= 25
  

• The arrow token, ->

• A body, which consists of a single expression or a statement block. This example uses the following expression:

  p.getGender() == Person.Sex.MALE 
      && p.getAge() >= 18
      && p.getAge() <= 25
  

  If you specify a single expression, then the Java runtime evaluates the expression and then returns its value. Alternatively, you can use a return statement:

  p -> {
      return p.getGender() == Person.Sex.MALE
          && p.getAge() >= 18
          && p.getAge() <= 25;
  }
  

  A return statement is not an expression; in a lambda expression, you must enclose statements in braces ({}). However, you do not have to enclose a void method invocation in braces. For example, the following is a valid lambda expression:

  email -> System.out.println(email)
  

Note that a lambda expression looks a lot like a method declaration; you can consider lambda expressions as anonymous methods—methods without a name.

Here is how you can "pass a method" using a lambda expression:

interface I {
    public void myMethod(Component component);
}

class A {
    public void changeColor(Component component) {
        // code here
    }

    public void changeSize(Component component) {
        // code here
    }
}

class B {
    public void setAllComponents(Component[] myComponentArray, I myMethodsInterface) {
        for(Component leaf : myComponentArray) {
            if(leaf instanceof Container) { // recursive call if Container
                Container node = (Container)leaf;
                setAllComponents(node.getComponents(), myMethodInterface);
            } // end if node
            myMethodsInterface.myMethod(leaf);
        } // end looping through components
    }
}

class C {
    A a = new A();
    B b = new B();

    public C() {
        b.setAllComponents(this.getComponents(), component -> a.changeColor(component));
        b.setAllComponents(this.getComponents(), component -> a.changeSize(component));
    }
}

Class C can be shortened even a bit further by the use of method references like so:

class C {
    A a = new A();
    B b = new B();

    public C() {
        b.setAllComponents(this.getComponents(), a::changeColor);
        b.setAllComponents(this.getComponents(), a::changeSize);
    }
}

I found a better, but buggy way, combining sdleihssirhc's idea:

window.onscroll = function() {
    window.scrollTo(window.scrollX, window.scrollY);
    //Or
    //window.scroll(window.scrollX, window.scrollY);
    //Or Fallback
    //window.scrollX=window.scrollX;
    //window.scrollY=window.scrollY;
};

I didn't test it, but I'll edit later and let you all know. I'm 85% sure it works on major browsers.

import java.util.*;

class GetCurrentmonth
{
    public static void main(String args[])
    {
        int month;
        GregorianCalendar date = new GregorianCalendar();      
        month = date.get(Calendar.MONTH);
        month = month+1;
        System.out.println("Current month is  " + month);
    }
}

I followed the instructions above by Gene in Android Studio 1.5.1 but it added this to my build.gradle file:

compile 'platforms:android:android-support-v4:23.1.1'

so I changed it to:

compile 'com.android.support:support-v4:23.1.1'

And it started working.

Usually when you have a '\r' at the end of the string, only carriage return is printed without any newline. If you have the following:

printf("fooooo\r");
printf("bar");

the output will be:

barooo

One thing I can suggest (maybe a workaround) is to have a NULL terminated fixed size string that is initialized to all space characters, ending in a '\r' (every time before printing), and then use strcpy to copy your string into it (without the newline), so every subsequent print will overwrite the previous string. Something like this:

char str[MAX_LENGTH];        
// init str to all spaces, NULL terminated with character as '\r'
strcpy(str, my_string);       // copy my_string into str
str[strlen(my_string)] = ' '; // erase null termination char
str[MAX_LENGTH - 1] = '\r';
printf(str);

You can do error checking so that my_string is always atleast one less in length than str, but you get the basic idea.

use jquery :  $("#id").css("background","red");

I have started to get this issue when updated my xCode into Version 11.0 (11A420a). To solved that I have installed additional simulator version 12.2 and updated my iPhone version into 13.1. Now both on iOs simulator and on my device break points get hit.

This should do the work

import datetime
datetime.datetime.now().strftime("%H:%M:%S.%f")

It will print

HH:MM:SS.microseconds like this e.g 14:38:19.425961

I know this question is old now, but after doing a ton of research on various solutions to this problem, I think I may have come up with a better solution.

UPDATE 1: Since posting this answer, I have added all of this code to a simple service that I have posted to GitHub. The repo is located here. Feel free to check it out for more info.

UPDATE 2: This answer is great if all you need is a lightweight solution for pulling in stylesheets for your routes. If you want a more complete solution for managing on-demand stylesheets throughout your application, you may want to checkout Door3's AngularCSS project. It provides much more fine-grained functionality.

In case anyone in the future is interested, here's what I came up with:

1. Create a custom directive for the <head> element:

app.directive('head', ['$rootScope','$compile',
    function($rootScope, $compile){
        return {
            restrict: 'E',
            link: function(scope, elem){
                var html = '<link rel="stylesheet" ng-repeat="(routeCtrl, cssUrl) in routeStyles" ng-href="{{cssUrl}}" />';
                elem.append($compile(html)(scope));
                scope.routeStyles = {};
                $rootScope.$on('$routeChangeStart', function (e, next, current) {
                    if(current && current.$$route && current.$$route.css){
                        if(!angular.isArray(current.$$route.css)){
                            current.$$route.css = [current.$$route.css];
                        }
                        angular.forEach(current.$$route.css, function(sheet){
                            delete scope.routeStyles[sheet];
                        });
                    }
                    if(next && next.$$route && next.$$route.css){
                        if(!angular.isArray(next.$$route.css)){
                            next.$$route.css = [next.$$route.css];
                        }
                        angular.forEach(next.$$route.css, function(sheet){
                            scope.routeStyles[sheet] = sheet;
                        });
                    }
                });
            }
        };
    }
]);

This directive does the following things:

1. It compiles (using $compile) an html string that creates a set of <link /> tags for every item in the scope.routeStyles object using ng-repeat and ng-href.
2. It appends that compiled set of <link /> elements to the <head> tag.
3. It then uses the $rootScope to listen for '$routeChangeStart' events. For every '$routeChangeStart' event, it grabs the "current" $$route object (the route that the user is about to leave) and removes its partial-specific css file(s) from the <head> tag. It also grabs the "next" $$route object (the route that the user is about to go to) and adds any of its partial-specific css file(s) to the <head> tag.
4. And the ng-repeat part of the compiled <link /> tag handles all of the adding and removing of the page-specific stylesheets based on what gets added to or removed from the scope.routeStyles object.

Note: this requires that your ng-app attribute is on the <html> element, not on <body> or anything inside of <html>.

2. Specify which stylesheets belong to which routes using the $routeProvider:

app.config(['$routeProvider', function($routeProvider){
    $routeProvider
        .when('/some/route/1', {
            templateUrl: 'partials/partial1.html', 
            controller: 'Partial1Ctrl',
            css: 'css/partial1.css'
        })
        .when('/some/route/2', {
            templateUrl: 'partials/partial2.html',
            controller: 'Partial2Ctrl'
        })
        .when('/some/route/3', {
            templateUrl: 'partials/partial3.html',
            controller: 'Partial3Ctrl',
            css: ['css/partial3_1.css','css/partial3_2.css']
        })
}]);

This config adds a custom css property to the object that is used to setup each page's route. That object gets passed to each '$routeChangeStart' event as .$$route. So when listening to the '$routeChangeStart' event, we can grab the css property that we specified and append/remove those <link /> tags as needed. Note that specifying a css property on the route is completely optional, as it was omitted from the '/some/route/2' example. If the route doesn't have a css property, the <head> directive will simply do nothing for that route. Note also that you can even have multiple page-specific stylesheets per route, as in the '/some/route/3' example above, where the css property is an array of relative paths to the stylesheets needed for that route.

3. You're done Those two things setup everything that was needed and it does it, in my opinion, with the cleanest code possible.

Hope that helps someone else who might be struggling with this issue as much as I was.

The manual page (or the online GNU manual) pretty much explains everything.

find -exec command {} \;

For each result, command {} is executed. All occurences of {} are replaced by the filename. ; is prefixed with a slash to prevent the shell from interpreting it.

find -exec command {} +

Each result is appended to command and executed afterwards. Taking the command length limitations into account, I guess that this command may be executed more times, with the manual page supporting me:

the total number of invocations of the command will be much less than the number of matched files.

Note this quote from the manual page:

The command line is built in much the same way that xargs builds its command lines

That's why no characters are allowed between {} and + except for whitespace. + makes find detect that the arguments should be appended to the command just like xargs.

The solution

Luckily, the GNU implementation of mv can accept the target directory as an argument, with either -t or the longer parameter --target. It's usage will be:

mv -t target file1 file2 ...

Your find command becomes:

find . -type f -iname '*.cpp' -exec mv -t ./test/ {} \+

From the manual page:

-exec command ;

Execute command; true if 0 status is returned. All following arguments to find are taken to be arguments to the command until an argument consisting of `;' is encountered. The string `{}' is replaced by the current file name being processed everywhere it occurs in the arguments to the command, not just in arguments where it is alone, as in some versions of find. Both of these constructions might need to be escaped (with a `\') or quoted to protect them from expansion by the shell. See the EXAMPLES section for examples of the use of the -exec option. The specified command is run once for each matched file. The command is executed in the starting directory. There are unavoidable security problems surrounding use of the -exec action; you should use the -execdir option instead.

-exec command {} +

This variant of the -exec action runs the specified command on the selected files, but the command line is built by appending each selected file name at the end; the total number of invocations of the command will be much less than the number of matched files. The command line is built in much the same way that xargs builds its command lines. Only one instance of `{}' is allowed within the command. The command is executed in the starting directory.

It will be something like this:

SELECT b.Title, b.Edition, b.Year, b.Pages, b.Rating, c.Category, p.Publisher, w.LastName
FROM
    Books b
    JOIN Categories_Book cb ON cb._ISBN = b._Books_ISBN
    JOIN Category c ON c._CategoryID = cb._Categories_Category_ID
    JOIN Publishers p ON p._PublisherID = b.PublisherID
    JOIN Writers_Books wb ON wb._Books_ISBN = b._ISBN
    JOIN Writer w ON w._WritersID = wb._Writers_WriterID

You use the join statement to indicate which fields from table A map to table B. I'm using aliases here thats why you see Books b the Books table will be referred to as b in the rest of the query. This makes for less typing.

FYI your naming convention is very strange, I would expect it to be more like this:

Book: ID, ISBN , BookTitle, Edition, Year, PublisherID, Pages, Rating
Category: ID, [Name]
BookCategory: ID, CategoryID, BookID
Publisher: ID, [Name]
Writer: ID, LastName
BookWriter: ID, WriterID, BookID

I would concatenate the old list and new list as streams and save the results to destination list. Works well in parallel, too.

I will use the example of accepted answer given by Stuart Marks:

List<String> destList = Arrays.asList("foo");
List<String> newList = Arrays.asList("0", "1", "2", "3", "4", "5");

destList = Stream.concat(destList.stream(), newList.stream()).parallel()
            .collect(Collectors.toList());
System.out.println(destList);

//output: [foo, 0, 1, 2, 3, 4, 5]

Hope it helps.

Edit / Update:

If you are using Typescript 3.7 or newer you can now also do:

    const data = change?.after?.data();

    if(!data) {
      console.error('No data here!');
       return null
    }

    const maxLen = 100;
    const msgLen = data.messages.length;
    const charLen = JSON.stringify(data).length;

    const batch = db.batch();

    if (charLen >= 10000 || msgLen >= maxLen) {

      // Always delete at least 1 message
      const deleteCount = msgLen - maxLen <= 0 ? 1 : msgLen - maxLen
      data.messages.splice(0, deleteCount);

      const ref = db.collection("chats").doc(change.after.id);

      batch.set(ref, data, { merge: true });

      return batch.commit();
    } else {
      return null;
    }

Original Response

Typescript is saying that change or data is possibly undefined (depending on what onUpdate returns).

So you should wrap it in a null/undefined check:

if(change && change.after && change.after.data){
    const data = change.after.data();

    const maxLen = 100;
    const msgLen = data.messages.length;
    const charLen = JSON.stringify(data).length;

    const batch = db.batch();

    if (charLen >= 10000 || msgLen >= maxLen) {

      // Always delete at least 1 message
      const deleteCount = msgLen - maxLen <= 0 ? 1 : msgLen - maxLen
      data.messages.splice(0, deleteCount);

      const ref = db.collection("chats").doc(change.after.id);

      batch.set(ref, data, { merge: true });

      return batch.commit();
    } else {
      return null;
    }
}

If you are 100% sure that your object is always defined then you can put this:

const data = change.after!.data();

Finally solved issue of reinitialization of select2 after ajax call.

You can call this in success function of ajax.

Note : Don't forget to replace ".selector" to your class of <select class="selector"> element.

jQuery('.select2-container').remove();

jQuery('.selector').select2({
   placeholder: "Placeholder text",
   allowClear: true
});

jQuery('.select2-container').css('width','100%');

use jQuery's $.getJSON

$.getJSON('mydata.json', function(data) {
    //do stuff with your data here
});

You can do something like this:

"1234567890".match(/.{1,2}/g);
// Results in:
["12", "34", "56", "78", "90"]

The method will still work with strings whose size is not an exact multiple of the chunk-size:

"123456789".match(/.{1,2}/g);
// Results in:
["12", "34", "56", "78", "9"]

In general, for any string out of which you want to extract at-most n-sized substrings, you would do:

str.match(/.{1,n}/g); // Replace n with the size of the substring

If your string can contain newlines or carriage returns, you would do:

str.match(/(.|[\r\n]){1,n}/g); // Replace n with the size of the substring

As far as performance, I tried this out with approximately 10k characters and it took a little over a second on Chrome. YMMV.

This can also be used in a reusable function:

function chunkString(str, length) {
  return str.match(new RegExp('.{1,' + length + '}', 'g'));
}

It's a bit hard to give a definitive answer without a bit more information, but one usual way is to register a startup script:

try
{
  ...
}
catch(ApplicationException ex){
  Page.ClientScript.RegisterStartupScript(this.GetType(),"ErrorAlert","alert('Some text here - maybe ex.Message');",true);
}

The encrypted string had two special characters, + and =.

'+' sign was giving the error, so below solution worked well:

//replace + sign

encryted_string = encryted_string.Replace("+", "%2b");

//`%2b` is HTTP encoded string for **+** sign

OR

//encode special charactes 

encryted_string = HttpUtility.UrlEncode(encryted_string);

//then pass it to the decryption process
...

The reason i could not delete some of the users via 'drop' statement was that there is a bug in Mysql http://bugs.mysql.com/bug.php?id=62255 with hostname containing upper case letters. The solution was running following query:

DELETE FROM mysql.user where host='Some_Host_With_UpperCase_Letters';

I am still trying to figure the other issue where the root user with all permissions are unable to grant privileges to new user for particular database

That's because abc is undefined at the moment of the template rendering. You can use safe navigation operator (?) to "protect" template until HTTP call is completed:

{{abc?.xyz?.name}}

You can read more about safe navigation operator here.

Update:

Safe navigation operator can't be used in arrays, you will have to take advantage of NgIf directive to overcome this problem:

<div *ngIf="arr && arr.length > 0">
    {{arr[0].name}}
</div>

Read more about NgIf directive here.

None of these worked for me.

My class libraries were definitely all referencing both System.Core and Microsoft.CSharp. Web Application was 4.0 and couldn't upgrade to 4.5 due to support issues.

I was encountering the error compiling a razor template using the Razor Engine, and only encountering it intermittently, like after web application has been restarted.

The solution that worked for me was manually loading the assembly then reattempting the same operation...

        bool retry = true;
        while (retry)
        {
            try
            {
                string textTemplate = File.ReadAllText(templatePath);
                Razor.CompileWithAnonymous(textTemplate, templateFileName);
                retry = false;
            }
            catch (TemplateCompilationException ex)
            {
                LogTemplateException(templatePath, ex);
                retry = false;

                if (ex.Errors.Any(e  => e.ErrorNumber == "CS1969"))
                {
                    try
                    {
                        _logger.InfoFormat("Attempting to manually load the Microsoft.CSharp.RuntimeBinder.Binder");
                        Assembly csharp = Assembly.Load("Microsoft.CSharp, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a");
                        Type type = csharp.GetType("Microsoft.CSharp.RuntimeBinder.Binder");
                        retry = true;
                    }
                    catch(Exception exLoad)
                    {
                        _logger.Error("Failed to manually load runtime binder", exLoad);
                    }
                }

                if (!retry)
                    throw;
            }
        }

Hopefully this might help someone else out there.

You need a /g on there, like this:

var textTitle = "this is a test";_x000D_
var result = textTitle.replace(/ /g, '%20');_x000D_
_x000D_
console.log(result);

You can play with it here, the default .replace() behavior is to replace only the first match, the /g modifier (global) tells it to replace all occurrences.

connect timeout has to be handled with a non-blocking socket (GNU LibC documentation on connect). You get connect to return immediately and then use select to wait with a timeout for the connection to complete.

This is also explained here : Operation now in progress error on connect( function) error.

int wait_on_sock(int sock, long timeout, int r, int w)
{
    struct timeval tv = {0,0};
    fd_set fdset;
    fd_set *rfds, *wfds;
    int n, so_error;
    unsigned so_len;

    FD_ZERO (&fdset);
    FD_SET  (sock, &fdset);
    tv.tv_sec = timeout;
    tv.tv_usec = 0;

    TRACES ("wait in progress tv={%ld,%ld} ...\n",
            tv.tv_sec, tv.tv_usec);

    if (r) rfds = &fdset; else rfds = NULL;
    if (w) wfds = &fdset; else wfds = NULL;

    TEMP_FAILURE_RETRY (n = select (sock+1, rfds, wfds, NULL, &tv));
    switch (n) {
    case 0:
        ERROR ("wait timed out\n");
        return -errno;
    case -1:
        ERROR_SYS ("error during wait\n");
        return -errno;
    default:
        // select tell us that sock is ready, test it
        so_len = sizeof(so_error);
        so_error = 0;
        getsockopt (sock, SOL_SOCKET, SO_ERROR, &so_error, &so_len);
        if (so_error == 0)
            return 0;
        errno = so_error;
        ERROR_SYS ("wait failed\n");
        return -errno;
    }
}

GROUP BY has a very specific meaning that is distinct (heh) from the DISTINCT function.

GROUP BY causes the query results to be grouped using the chosen expression, aggregate functions can then be applied, and these will act on each group, rather than the entire resultset.

Here's an example that might help:

Given a table that looks like this:

name
------
barry
dave
bill
dave
dave
barry
john

This query:

SELECT name, count(*) AS count FROM table GROUP BY name;

Will produce output like this:

name    count
-------------
barry   2
dave    3
bill    1
john    1

Which is obviously very different from using DISTINCT. If you want to group your results, use GROUP BY, if you just want a unique list of a specific column, use DISTINCT. This will give your database a chance to optimise the query for your needs.

The above suggestions did not work for me. What really worked was the inclusion of the following lines in the application.properties

spring.datasource.testWhileIdle = true
spring.datasource.timeBetweenEvictionRunsMillis = 3600000
spring.datasource.validationQuery = SELECT 1

You can find the explanation out here

finally is always executed unless there is abnormal program termination (like calling System.exit(0)..). so, your sysout will get printed

There is also an 'E' status

E = File existed before update

This can happen if you have manually created a folder that would have been created by performing an update.

Depending on the use case, you might also want to disable the buffering in the subprocess itself.

If the subprocess will be a Python process, you could do this before the call:

os.environ["PYTHONUNBUFFERED"] = "1"

Or alternatively pass this in the env argument to Popen.

Otherwise, if you are on Linux/Unix, you can use the stdbuf tool. E.g. like:

cmd = ["stdbuf", "-oL"] + cmd

See also here about stdbuf or other options.

(See also here for the same answer.)

Here's a beautiful dynamic function I wrote to remove last part of url or path.

/**
 * remove the last directories
 *
 * @param $path the path
 * @param $level number of directories to remove
 *
 * @return string
 */
private function removeLastDir($path, $level)
{
    if(is_int($level) && $level > 0){
        $path = preg_replace('#\/[^/]*$#', '', $path);
        return $this->removeLastDir($path, (int) $level - 1);
    }
    return $path;
}

just look at cv2.randu() or cv.randn(), it's all pretty similar to matlab already, i guess.

let's play a bit ;) :

import cv2
import numpy as np

>>> im = np.empty((5,5), np.uint8) # needs preallocated input image
>>> im
array([[248, 168,  58,   2,   1],  # uninitialized memory counts as random, too ?  fun ;) 
       [  0, 100,   2,   0, 101],
       [  0,   0, 106,   2,   0],
       [131,   2,   0,  90,   3],
       [  0, 100,   1,   0,  83]], dtype=uint8)
>>> im = np.zeros((5,5), np.uint8) # seriously now.
>>> im
array([[0, 0, 0, 0, 0],
       [0, 0, 0, 0, 0],
       [0, 0, 0, 0, 0],
       [0, 0, 0, 0, 0],
       [0, 0, 0, 0, 0]], dtype=uint8)
>>> cv2.randn(im,(0),(99))         # normal
array([[  0,  76,   0, 129,   0],
       [  0,   0,   0, 188,  27],
       [  0, 152,   0,   0,   0],
       [  0,   0, 134,  79,   0],
       [  0, 181,  36, 128,   0]], dtype=uint8)
>>> cv2.randu(im,(0),(99))         # uniform
array([[19, 53,  2, 86, 82],
       [86, 73, 40, 64, 78],
       [34, 20, 62, 80,  7],
       [24, 92, 37, 60, 72],
       [40, 12, 27, 33, 18]], dtype=uint8)

to apply it to an existing image, just generate noise in the desired range, and add it:

img = ...
noise = ...

image = img + noise

Somthing like this should workL

SELECT BookingId, StartTime
FROM Booking
WHERE StartTime between dateadd(hour, -1, getdate()) and getdate()

Hey guys the code below worked perfectly fine for me. Just replace the setFrom and addAddress with your preference and that's it.

When you do self.button = Button(...).grid(...), what gets assigned to self.button is the result of the grid() command, not a reference to the Button object created.

You need to assign your self.button variable before packing/griding it. It should look something like this:

self.button = Button(self,text="Click Me",command=self.color_change,bg="blue")
self.button.grid(row = 2, column = 2, sticky = W)

This version works better on Windows than the top answer because it understands both / and path.sep so that forward slashes work on Windows as they should. Supports absolute and relative paths (relative to the process.cwd).

 * condition if two processes are creating a folder. Throws on error.
 * @param targetDir Name of folder to create
 */
export function mkdirSyncRecursive(targetDir) {
  if (!fs.existsSync(targetDir)) {
    for (var i = targetDir.length-2; i >= 0; i--) {
      if (targetDir.charAt(i) == '/' || targetDir.charAt(i) == path.sep) {
        mkdirSyncRecursive(targetDir.slice(0, i));
        break;
      }
    }
    try {
      fs.mkdirSync(targetDir);
      return true;
    } catch (err) {
      if (err.code !== 'EEXIST') throw err;
    }
  }
  return false;
}

You can also use button click event like this:

<asp:TemplateField>
    <ItemTemplate>
        <asp:Button ID="Button1" runat="server" Text="Button" 
                    OnClick="MyButtonClick" />
    </ItemTemplate>
</asp:TemplateField>

protected void MyButtonClick(object sender, System.EventArgs e)
{
    //Get the button that raised the event
    Button btn = (Button)sender;

    //Get the row that contains this button
    GridViewRow gvr = (GridViewRow)btn.NamingContainer;
} 

OR

You can do like this to get data:

 void CustomersGridView_RowCommand(Object sender, GridViewCommandEventArgs e)
 {

    // If multiple ButtonField column fields are used, use the
    // CommandName property to determine which button was clicked.
    if(e.CommandName=="Select")
    {
      // Convert the row index stored in the CommandArgument
      // property to an Integer.
      int index = Convert.ToInt32(e.CommandArgument);    

      // Get the last name of the selected author from the appropriate
      // cell in the GridView control.
      GridViewRow selectedRow = CustomersGridView.Rows[index];
    }
}

and Button in gridview should have command like this and handle rowcommand event:

<asp:gridview id="CustomersGridView" 
        datasourceid="CustomersSqlDataSource" 
        autogeneratecolumns="false"
        onrowcommand="CustomersGridView_RowCommand"
        runat="server">

        <columns>
          <asp:buttonfield buttontype="Button" 
            commandname="Select"
            headertext="Select Customer" 
            text="Select"/>
        </columns>
  </asp:gridview>

getText(): Get the visible (i.e. not hidden by CSS) innerText of this element, including sub-elements, without any leading or trailing whitespace.

getAttribute(String attrName): Get the value of a the given attribute of the element. Will return the current value, even if this has been modified after the page has been loaded. More exactly, this method will return the value of the given attribute, unless that attribute is not present, in which case the value of the property with the same name is returned (for example for the "value" property of a textarea element). If neither value is set, null is returned. The "style" attribute is converted as best can be to a text representation with a trailing semi-colon. The following are deemed to be "boolean" attributes, and will return either "true" or null: async, autofocus, autoplay, checked, compact, complete, controls, declare, defaultchecked, defaultselected, defer, disabled, draggable, ended, formnovalidate, hidden, indeterminate, iscontenteditable, ismap, itemscope, loop, multiple, muted, nohref, noresize, noshade, novalidate, nowrap, open, paused, pubdate, readonly, required, reversed, scoped, seamless, seeking, selected, spellcheck, truespeed, willvalidate Finally, the following commonly mis-capitalized attribute/property names are evaluated as expected: "class" "readonly"

getText() return the visible text of the element.

getAttribute(String attrName) returns the value of the attribute passed as parameter.

if you datatype is datetime of the table.col , then database store data contain two partial : 1 (date) 2 (time)

Just in display data use convert or cast.

Example:

create table #test(part varchar(10),lastTime datetime)
go

insert into #test (part ,lastTime )
values('A','2012-11-05 ')

insert into #test (part ,lastTime )
values('B','2012-11-05 10:30')


go

select * from #test 

A   2012-11-05 00:00:00.000
B   2012-11-05 10:30:00.000

select part,CONVERT (varchar,lastTime,111) from #test

A   2012/11/05
B   2012/11/05

select part,CONVERT (varchar(10),lastTime,20) from #test 

A   2012-11-05
B   2012-11-05

You can load configuration without builder function, you can just inject it.

public IConfiguration Configuration { get; set; }

public Startup(IConfiguration configuration)
{
   Configuration = configuration;
}

You'll want to change the extension of your css file from .css.scss to .css.scss.erb and do:

background-image:url(<%=asset_path "admin/logo.png"%>);

You may need to do a "hard refresh" to see changes. CMD+SHIFT+R on OSX browsers.

In production, make sure

rm -rf public/assets    
bundle exec rake assets:precompile RAILS_ENV=production

happens upon deployment.

As an important issue, when you want to utilize shell to delete .svn folders You need -depth argument to prevent find command entering the directory that was just deleted and showing error messages like e.g.

"find: ./.svn: No such file or directory"

As a result, You can use find command like below:

cd [dir_to_delete_svn_folders]
find . -depth -name .svn -exec rm -fr {} \;
