This is one way to do it:

string = "this is a string"
ssplit = string.split()
for word in ssplit:
    print (word)

Output:

this
is
a
string

If I understand you question correctly, you could create a wrapper around your marquee and then assign a width (or max-width) to the wrapping element. For example:

<div id="marquee-wrapper">
    <div class="marquee">This is a marquee!</div>   
</div>

And then #marquee-wrapper { width: x }.

The techniques outlined above describe your options pretty well. But what are the users seeing? I can't imagine how a basic conflict like this between you and whoever is responsible for the software can't end up in confusion and antagonism with the users.

I'd do everything I could to find some other way out of the impasse - because other people could easily see any change you make as escalating the problem.

EDIT:

I'll score my first "undelete" and admit to posting the above when this question first appeared. I of course chickened out when I saw that it was from JOEL SPOLSKY. But it looks like it landed somewhere near. Don't need votes, but I'll put it on the record.

IME, triggers are so seldom the right answer for anything other than fine-grained integrity constraints outside the realm of business rules.

I think the best solution I have come across is on this stackoverflow. This short jQuery code allows all your hover effects to show on click or touch..
No need to add anything within the function.

$('body').on('touchstart', function() {});

Hope this helps.

If you're using Eclipse, just have your WSDL in a .wsdl file, eclipse will validate it automatically.

From the Doc

The WSDL validator handles validation according to the 4 step process defined above. Steps 1 and 2 are both delegated to Apache Xerces (and XML parser). Step 3 is handled by the WSDL validator and any extension namespace validators (more on extensions below). Step 4 is handled by any declared custom validators (more on this below as well). Each step must pass in order for the next step to run.

I had a similar problem.

When I entered

<activity android:name="MyActivity" android:screenOrientation="landscape"></activity>

In the manifest file this caused that activity to display in landscape. However when I returned to previous activities they displayed in lanscape even though they were set to portrait. However by adding

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

immediately after the OnCreate section of the target activity resolved the problem. So I now use both methods.

sysdate-(2/11)

A day consists of 24 hours. So, to subtract 2 hours from a day you need to divide it by 24:

DATE_value - 2/24

Using interval for the same:

DATE_value - interval '2' hour

You can use this simple code:

One-liner in Kotlin:

window.statusBarColor = ContextCompat.getColor(this, R.color.colorName)

Original answer with Java & manual version check:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    getWindow().setStatusBarColor(getResources().getColor(R.color.colorAccentDark_light, this.getTheme()));
} else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    getWindow().setStatusBarColor(getResources().getColor(R.color.colorAccentDark_light));
}

You can use this syntax if some grads are attached with your variables.

y=torch.Tensor.cpu(x).detach().numpy()[:,:,:,-1]

You're declaring a virtual function and not defining it:

virtual void calculateCredits();

Either define it or declare it as:

virtual void calculateCredits() = 0;

Or simply:

virtual void calculateCredits() { };

To add to the above: If interrupt is not working, you can restart the kernel.

Go to the kernel dropdown >> restart >> restart and clear output. This usually does the trick. If this still doesn't work, kill the kernel in the terminal (or task manager) and then restart.

Interrupt doesn't work well for all processes. I especially have this problem using the R kernel.

For anyone looking for a regex:

const BLACKLIST = /[<>:"\/\\|?*]/g;

I had the exact same error, but then I later found out that I forget to activate the conda environment which had django and other required packages installed.

Solution: Create a conda or virtual environment with django installed, and activate it before you use the command: $ python manage.py migrate

Here is your solution for the problem,

$letter = array();
for ($i = 'A'; $i !== 'ZZ'; $i++){
        if(ord($i) % 2 != 0)
           $letter[] .= $i;
}
print_r($letter);

You need to get the ASCII value for that character which will solve your problem.

Here is ord doc and working code.

For your requirement, you can do like this,

for ($i = 'A'; $i !== 'ZZ'; ord($i)+$x){
  $letter[] .= $i;
}
print_r($letter);

Here set $x as per your requirement.

NGINX supports WebSockets by allowing a tunnel to be setup between a client and a backend server. In order for NGINX to send the Upgrade request from the client to the backend server, Upgrade and Connection headers must be set explicitly. For example:

# WebSocket proxying
map $http_upgrade $connection_upgrade {
    default         upgrade;
    ''              close;
}


server {
    listen 80;

    # The host name to respond to
    server_name cdn.domain.com;

    location / {
        # Backend nodejs server
        proxy_pass          http://127.0.0.1:8080;
        proxy_http_version  1.1;
        proxy_set_header    Upgrade     $http_upgrade;
        proxy_set_header    Connection  $connection_upgrade;
    }
}

With Web API 2.2: Request.GetOwinContext().Request.RemoteIpAddress

You just can't return the value directly because it is an async call. An async call means it is running in the background (actually scheduled for later execution) while your code continues to execute.

You also can't have such code in the class directly. It needs to be moved into a method or the constructor.

What you can do is not to subscribe() directly but use an operator like map()

export class DataComponent{
    someMethod() {
      return this.http.get(path).map(res => {
        return res.json();
      });
    }
}

In addition, you can combine multiple .map with the same Observables as sometimes this improves code clarity and keeps things separate. Example:

validateResponse = (response) => validate(response);

parseJson = (json) => JSON.parse(json);

fetchUnits() {
    return this.http.get(requestUrl).map(this.validateResponse).map(this.parseJson);
}

This way an observable will be return the caller can subscribe to

export class DataComponent{
    someMethod() {
      return this.http.get(path).map(res => {
        return res.json();
      });
    }

    otherMethod() {
      this.someMethod().subscribe(data => this.data = data);
    }
}

The caller can also be in another class. Here it's just for brevity.

data => this.data = data

and

res => return res.json()

are arrow functions. They are similar to normal functions. These functions are passed to subscribe(...) or map(...) to be called from the observable when data arrives from the response. This is why data can't be returned directly, because when someMethod() is completed, the data wasn't received yet.

I am assuming this is a custom font. For any custom font this is what you do.

1. First download and add your font files to your project in Xcode (The files should appear as well in “Target -> Build Phases -> Copy Bundle Resources”).

2. In your Info.plist file add the key “Fonts provided by application” with type “Array”.

3. For each font you want to add to your project, create an item for the array you have created with the full name of the file including its extension (e.g. HelveticaNeue-UltraLight.ttf). Save your “Info.plist” file.

label.font = UIFont (name: "HelveticaNeue-UltraLight", size: 30)

Make the outer div position="relative" and the inner div position="absolute" and set it's bottom="0".

Angular6 using the renderer2 without any variables and a clean template:

template:

<div (click)="toggleClass($event,'testClass')"></div>

in ts:

toggleClass(event: any, class: string) {
  const hasClass = event.target.classList.contains(class);

  if(hasClass) {
    this.renderer.removeClass(event.target, class);
  } else {
    this.renderer.addClass(event.target, class);
  }
}

One could put this in a directive too ;)

Check to see if there are any triggers on the table you are trying to execute queries against. They can sometimes throw this error as they are trying to run the update/select/insert trigger that is on the table.

You can modify your query to disable then enable the trigger if the trigger DOES NOT need to be executed for whatever query you are trying to run.

ALTER TABLE your_table DISABLE TRIGGER [the_trigger_name]

UPDATE    your_table
SET     Gender = 'Female'
WHERE     (Gender = 'Male')

ALTER TABLE your_table ENABLE TRIGGER [the_trigger_name]

'-replace' does a regex search and you have special characters in that last one (like +) So you might use the non-regex replace version like this:

$c = $c.replace('AccountKey=eKkij32jGEIYIEqAR5RjkKgf4OTiMO6SAyF68HsR/Zd/KXoKvSdjlUiiWyVV2+OUFOrVsd7jrzhldJPmfBBpQA==','DdOegAhDmLdsou6Ms6nPtP37bdw6EcXucuT47lf9kfClA6PjGTe3CfN+WVBJNWzqcQpWtZf10tgFhKrnN48lXA==')

Go to your client machine and type in:

nslookup server.company.com

substituting the real host name of your server for server.company.com, of course.

That should tell you which DNS server your client is using (if any) and what it thinks the problem is with the name.

To force an application to use an IP address, generally you just configure it to use the IP address instead of a host name. If the host name is hard-coded, or the application insists on using a host name in preference to an IP address (as one of your other comments seems to indicate), then you're probably out of luck there.

However, you can change the way that most machine resolve the host names, such as with /etc/resolv.conf and /etc/hosts on UNIXy systems and a local hosts file on Windows-y systems.

In Qt5 you should use QtWidgets instead of QtGui

#include <QtGui/QComboBox>     // incorrect in QT5
#include <QtWidgets/QComboBox>    // correct in QT5

Or

#include <QtGui/QStringListModel>    // incorrect in QT5
#include <QtCore/QStringListModel>    // correct in QT5

You can use input.value = JSON.stringify(obj) to transform the object to a string.
And when you need it back you can use obj = JSON.parse(input.value)

The JSON object is available on modern browsers or you can use the json2.js library from json.org

If you use plain logs - all your log records should correspond this rule: one record = one line. Following this rule you can use grep and other tools to process your log files.

But traceback information is multi-line. So my answer is an extended version of solution proposed by zangw above in this thread. The problem is that traceback lines could have \n inside, so we need to do an extra work to get rid of this line endings:

import logging


logger = logging.getLogger('your_logger_here')

def log_app_error(e: BaseException, level=logging.ERROR) -> None:
    e_traceback = traceback.format_exception(e.__class__, e, e.__traceback__)
    traceback_lines = []
    for line in [line.rstrip('\n') for line in e_traceback]:
        traceback_lines.extend(line.splitlines())
    logger.log(level, traceback_lines.__str__())

After that (when you'll be analyzing your logs) you could copy / paste required traceback lines from your log file and do this:

ex_traceback = ['line 1', 'line 2', ...]
for line in ex_traceback:
    print(line)

Profit!

Taking Milad's suggestion a bit further, you can break your document source down and then do another find, continuing until you find the unmatched culprit.

When you are working with many modules (using a CMS), or don't have access to the W3C tool (because you are working locally), this approach is really helpful.

To track down the correct parameters you need to go first to ?plot.default, which refers you to ?par and ?axis:

plot(1, 1 ,xlab="x axis", ylab="y axis",  pch=19,
           col.lab="red", cex.lab=1.5,    #  for the xlab and ylab
           col="green")                   #  for the points

Turns out that the post (or rather the whole table) was locked by the very same connection that I tried to update the post with.

I had a opened record set of the post that was created by:

Set RecSet = Conn.Execute()

This type of recordset is supposed to be read-only and when I was using MS Access as database it did not lock anything. But apparently this type of record set did lock something on MS SQL Server 2012 because when I added these lines of code before executing the UPDATE SQL statement...

RecSet.Close
Set RecSet = Nothing

...everything worked just fine.

So bottom line is to be careful with opened record sets - even if they are read-only they could lock your table from updates.

Your Question is :

My default git folder is C:\Users\username.git

But I want to go into c:/project

What command do I need to get into that?

Since you have asked primarily about gitbash which is Linux based (Terminal), there are differences in commands when compared with Command Prompt of Windows. We'll discuss gitbash (Terminal) commands only.

1.First of all we must understand that command line(In Windows) and Terminal(In Mac) always points to some folder on storage Drives .

To check towards what directory it is pointing to at any given time. You need to type the command: pwd "an acronym for 'Print Working Directory' ".

2. There is a command ls which gives us information about the folders and files in a particular directory. This is quite a handy command and often used to know about the file structure. In my answer I will make use of this also.

3. To traverse along the folder tree we make use of yet another very important command know as cd which stands for change directory. And your question has the answer within this cd command only.

Here are some of the ways to traverse along the folder tree:

3a) cd command let's us traverse to child directory. Kindly check the snapshot.

3b) Now to traverse back into the parent directory, we make use of cd .. command: Please check the Image below:

By Using the above two steps we can easily solve your Query:

A) Currently you are in : C:\Users\username.git

So, doing cd .. will point the Terminal towards Users folder.

B) Again Typing cd .. will make Terminal to point towards C Drive.

C) Now doing ls at this point will let you know about all the folders and files in C drive.

Check if there is a project folder, Then simply for the last time type the command:

cd project

And Walla you are have traveled so far to reach to your destination. Congratulations.

Note: If the project folder is not created with C drive, simply write the command mkdir project and it will be created. Then follow the above steps to play around.

4) There is one more straight forward quick solution to your problem in particular:

Wherever the terminal is pointing. Simply write the command:

4a) cd / It will point to default root folder.

Then type the command : cd /c/ to point towards c directory. Then simply go to child directory, which in your case is project directory by typing:

cd project

And you are good to go: ENJOY :)

Go to styles.xml and change .DarkActionBar for .NoActionBar

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
</style>

becomes

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
</style>

if colors are irrelevant to your app, you can actually go for

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar" />

What you are talking about is called dot sourcing. And it's evil. But no worries, there is a better and easier way to do what you are wanting with modules (it sounds way scarier than it is). The major benefit of using modules is that you can unload them from the shell if you need to, and it keeps the variables in the functions from creeping into the shell (once you dot source a function file, try calling one of the variables from a function in the shell, and you'll see what I mean).

So first, rename the .ps1 file that has all your functions in it to MyFunctions.psm1 (you've just created a module!). Now for a module to load properly, you have to do some specific things with the file. First for Import-Module to see the module (you use this cmdlet to load the module into the shell), it has to be in a specific location. The default path to the modules folder is $home\Documents\WindowsPowerShell\Modules.

In that folder, create a folder named MyFunctions, and place the MyFunctions.psm1 file into it (the module file must reside in a folder with exactly the same name as the PSM1 file).

Once that is done, open PowerShell, and run this command:

Get-Module -listavailable

If you see one called MyFunctions, you did it right, and your module is ready to be loaded (this is just to ensure that this is set up right, you only have to do this once).

To use the module, type the following in the shell (or put this line in your $profile, or put this as the first line in a script):

Import-Module MyFunctions

You can now run your functions. The cool thing about this is that once you have 10-15 functions in there, you're going to forget the name of a couple. If you have them in a module, you can run the following command to get a list of all the functions in your module:

Get-Command -module MyFunctions

It's pretty sweet, and the tiny bit of effort that it takes to set up on the front side is WAY worth it.

setInterval(function () {document.getElementById("myButtonId").click();}, 1000);

Django is designed to be easely used to deliver web pages. If you are not confortable with this perhaps you should use another solution.

I'm writting the root or common operations on the model (to have the same interface) and the others on the controller of the model. If I need an operation from other model I import its controller.

This approach it's enough for me and the complexity of my applications.

Hedde's response is an example that shows the flexibility of django and python itself.

Very interesting question anyway!

If you find that PIL has problems on some platforms, using a native image viewer may help.

img.save("tmp.png") #Save the image to a PNG file called tmp.png.

For MacOS:

import os
os.system("open tmp.png") #Will open in Preview.

For most GNU/Linux systems with X.Org and a desktop environment:

import os
os.system("xdg-open tmp.png")

For Windows:

import os
os.system("powershell -c tmp.png")

Or you can hack it up.

Items.All(p => { p.IsAwesome = true; return true; });

Are you running C++ 11? stoi was added in C++ 11, if you're running on an older version use atoi()

I think you can use Padding like: Hope this one can help you.

.loginButton {
    background:url(images/loginBtn-center.jpg) repeat-x;
    width:175px;
    height:65px;
    margin:20px auto;
    border-radius:10px;
    -webkit-border-radius:10px;
    box-shadow:0 1px 2px #5e5d5b;
    <!--Using padding to align text in box or image-->
    padding: 3px 2px;
}

use FileInputStream's readLine() method to read and parse the returned String to int using Integer.parseInt() method.

Spring 5 has some builtin helper classes for that: org/springframework/jdbc/support/incrementer

If insertion order matters, take a look at collections.OrderedDict:

An OrderedDict is a dict that remembers the order that keys were first inserted. If a new entry overwrites an existing entry, the original insertion position is left unchanged. Deleting an entry and reinserting it will move it to the end.

In [1]: from collections import OrderedDict

In [2]: od = OrderedDict(zip('bar','foo'))

In [3]: od
Out[3]: OrderedDict([('b', 'f'), ('a', 'o'), ('r', 'o')])

In [4]: od.keys()[-1]
Out[4]: 'r'

In [5]: od.popitem() # also removes the last item
Out[5]: ('r', 'o')

Update:

An OrderedDict is no longer necessary as dictionary keys are officially ordered in insertion order as of Python 3.7 (unofficially in 3.6).

For these recent Python versions, you can instead just use list(my_dict)[-1] or list(my_dict.keys())[-1].

Alternatively you can use ljust/rjust to make the formatting nicer.

print "%s%s" % (str(count).rjust(10), conv)

or

print str(count).ljust(10), conv

To clarify, the above example does work, my code in the example did not work for unrelated reasons.

If myvar is false, null or has never been used before (i.e. $scope.myvar or $rootScope.myvar never called), the div will not show. Once any value has been assigned to it, the div will show, except if the value is specifically false.

The following will cause the div to show:

$scope.myvar = "Hello World";

or

$scope.myvar = true;

The following will hide the div:

$scope.myvar = null;

or

$scope.myvar = false;

>>> thetuple = (1, 2, 3)
>>> print "this is a tuple: %s" % (thetuple,)
this is a tuple: (1, 2, 3)

Making a singleton tuple with the tuple of interest as the only item, i.e. the (thetuple,) part, is the key bit here.

Diffuse is also very good. It even lets you easily adjust how lines are matched up, by defining match-points.

You can use the following:

<style type="text/css">
   table { page-break-inside:auto }
   tr    { page-break-inside:avoid; page-break-after:auto }
</style>

Refer the W3C's CSS Print Profile specification for details.

And also refer the Salesforce developer forums.

we can follow below procedure to avoid display of key-values in alphabetical order.

What about this formula for getting the last value:

=index(G:G;max((G:G<>"")*row(G:G)))

And this would be a final formula for your original task:

=DAYS360(G10;index(G:G;max((G:G<>"")*row(G:G))))

Suppose that your initial date is in G10.

Try using the InStr function which returns the index in the string at which the character was found. If InStr returns 0, the string was not found.

If InStr(myString, "A") > 0 Then

InStr MSDN Website

For the error on the line assigning to newStr, convert oldStr.IndexOf to that InStr function also.

Left(oldStr, InStr(oldStr, "A"))

Gson can also be used to serialize arbitrarily complex objects.

Here is how you use it:

Gson gson = new Gson(); 
String json = gson.toJson(myObject); 

Gson will automatically convert collections to JSON arrays. Gson can serialize private fields and automatically ignores transient fields.

This one worked fine for me :)

$('.progress-image').each(function(){
    var img = new Image();
    img.onload = function() {
        let imgSrc = $(this).attr('src');
        $('.progress-image').each(function(){
            if($(this).attr('src') == imgSrc){
                console.log($(this).parent().closest('.real-pack').parent().find('.shimmer').fadeOut())
            }
        })
    }
    img.src = $(this).attr('src');
});

You can only access overridden methods in the overriding methods (or in other methods of the overriding class).

So: either don't override method2() or call super.method2() inside the overridden version.

The short-circuiting boolean operators (and, or) can't be overriden because there is no satisfying way to do this without introducing new language features or sacrificing short circuiting. As you may or may not know, they evaluate the first operand for its truth value, and depending on that value, either evaluate and return the second argument, or don't evaluate the second argument and return the first:

something_true and x -> x
something_false and x -> something_false
something_true or x -> something_true
something_false or x -> x

Note that the (result of evaluating the) actual operand is returned, not truth value thereof.

The only way to customize their behavior is to override __nonzero__ (renamed to __bool__ in Python 3), so you can affect which operand gets returned, but not return something different. Lists (and other collections) are defined to be "truthy" when they contain anything at all, and "falsey" when they are empty.

NumPy arrays reject that notion: For the use cases they aim at, two different notions of truth are common: (1) Whether any element is true, and (2) whether all elements are true. Since these two are completely (and silently) incompatible, and neither is clearly more correct or more common, NumPy refuses to guess and requires you to explicitly use .any() or .all().

& and | (and not, by the way) can be fully overriden, as they don't short circuit. They can return anything at all when overriden, and NumPy makes good use of that to do element-wise operations, as they do with practically any other scalar operation. Lists, on the other hand, don't broadcast operations across their elements. Just as mylist1 - mylist2 doesn't mean anything and mylist1 + mylist2 means something completely different, there is no & operator for lists.

The browsers have changed their privacy to autoplay video or audio due to Ads which is annoying. So you can just trick with below code.

You can put any silent audio in the iframe.

<iframe src="youraudiofile.mp3" type="audio/mp3" allow="autoplay" id="audio" style="display:none"></iframe>
<audio autoplay>
    <source src="youraudiofile.mp3" type="audio/mp3">
</audio>

Just add an invisible iframe with an .mp3 as its source and allow="autoplay" before the audio element. As a result, the browser is tricked into starting any subsequent audio file. Or autoplay a video that isn’t muted.

You should put the form inside each node and use ng-show and ng-hide to enable and disable editing, respectively. Something like this:

<li>
  <span ng-hide="editing" ng-click="editing = true">{{bday.name}} | {{bday.date}}</span>
  <form ng-show="editing" ng-submit="editing = false">
    <label>Name:</label>
    <input type="text" ng-model="bday.name" placeholder="Name" ng-required/>
    <label>Date:</label>
    <input type="date" ng-model="bday.date" placeholder="Date" ng-required/>
    <br/>
    <button class="btn" type="submit">Save</button>
   </form>
 </li>

The key points here are:

• I've changed controls ng-model to the local scope
• Added ng-show to form so we can show it while editing
• Added a span with a ng-hide to hide the content while editing
• Added a ng-click, that could be in any other element, that toggles editing to true
• Changed ng-submit to toggle editing to false

Sometimes, a Swift version of the "SQLite in 5 minutes or less" approach shown on sqlite.org is sufficient. The "5 minutes or less" approach uses sqlite3_exec() which is a convenience wrapper for sqlite3_prepare(), sqlite3_step(), sqlite3_column(), and sqlite3_finalize().

Swift 2.2 can directly support the sqlite3_exec() callback function pointer as either a global, non-instance procedure func or a non-capturing literal closure {}.

Readable typealias

typealias sqlite3 = COpaquePointer
typealias CCharHandle = UnsafeMutablePointer<UnsafeMutablePointer<CChar>>
typealias CCharPointer = UnsafeMutablePointer<CChar>
typealias CVoidPointer = UnsafeMutablePointer<Void>

Callback Approach

func callback(
    resultVoidPointer: CVoidPointer, // void *NotUsed 
    columnCount: CInt,               // int argc
    values: CCharHandle,             // char **argv     
    columns: CCharHandle             // char **azColName
    ) -> CInt {
    for  i in 0 ..< Int(columnCount) {
        guard let value = String.fromCString(values[i]) 
        else { continue }
        guard let column = String.fromCString(columns[i]) 
        else { continue }
        print("\(column) = \(value)")
    }
    return 0 // status ok
}

func sqlQueryCallbackBasic(argc: Int, argv: [String]) -> Int {
    var db: sqlite3 = nil 
    var zErrMsg:CCharPointer = nil
    var rc: Int32 = 0 // result code

    if argc != 3 {
        print(String(format: "ERROR: Usage: %s DATABASE SQL-STATEMENT", argv[0]))
        return 1
    }

    rc = sqlite3_open(argv[1], &db)
    if  rc != 0 {
        print("ERROR: sqlite3_open " + String.fromCString(sqlite3_errmsg(db))! ?? "" )
        sqlite3_close(db)
        return 1
    }

    rc = sqlite3_exec(db, argv[2], callback, nil, &zErrMsg)
    if rc != SQLITE_OK {
        print("ERROR: sqlite3_exec " + String.fromCString(zErrMsg)! ?? "")
        sqlite3_free(zErrMsg)
    }

    sqlite3_close(db)
    return 0
}

Closure Approach

func sqlQueryClosureBasic(argc argc: Int, argv: [String]) -> Int {
    var db: sqlite3 = nil 
    var zErrMsg:CCharPointer = nil
    var rc: Int32 = 0

    if argc != 3 {
        print(String(format: "ERROR: Usage: %s DATABASE SQL-STATEMENT", argv[0]))
        return 1
    }

    rc = sqlite3_open(argv[1], &db)
    if  rc != 0 {
        print("ERROR: sqlite3_open " + String.fromCString(sqlite3_errmsg(db))! ?? "" )
        sqlite3_close(db)
        return 1
    }

    rc = sqlite3_exec(
        db,      // database 
        argv[2], // statement
        {        // callback: non-capturing closure
            resultVoidPointer, columnCount, values, columns in

            for i in 0 ..< Int(columnCount) {
                guard let value = String.fromCString(values[i]) 
                else { continue }
                guard let column = String.fromCString(columns[i]) 
                else { continue }
                print("\(column) = \(value)")
            }
            return 0
        }, 
        nil, 
        &zErrMsg
    )

    if rc != SQLITE_OK {
        let errorMsg = String.fromCString(zErrMsg)! ?? ""
        print("ERROR: sqlite3_exec \(errorMsg)")
        sqlite3_free(zErrMsg)
    }
    sqlite3_close(db)
    return 0
}

To prepare an Xcode project to call a C library such as SQLite, one needs to (1) add a Bridging-Header.h file reference C headers like #import "sqlite3.h", (2) add Bridging-Header.h to Objective-C Bridging Header in project settings, and (3) add libsqlite3.tbd to Link Binary With Library target settings.

The sqlite.org's "SQLite in 5 minutes or less" example is implemented in a Swift Xcode7 project here.

You can make use of computeIfAbsent method in Map interface provided in Java 8.

final Map<String,AtomicLong> map = new ConcurrentHashMap<>();
map.computeIfAbsent("A", k->new AtomicLong(0)).incrementAndGet();
map.computeIfAbsent("B", k->new AtomicLong(0)).incrementAndGet();
map.computeIfAbsent("A", k->new AtomicLong(0)).incrementAndGet(); //[A=2, B=1]

The method computeIfAbsent checks if the specified key is already associated with a value or not? If no associated value then it attempts to compute its value using the given mapping function. In any case it returns the current (existing or computed) value associated with the specified key, or null if the computed value is null.

On a side note if you have a situation where multiple threads update a common sum you can have a look at LongAdder class.Under high contention, expected throughput of this class is significantly higher than AtomicLong, at the expense of higher space consumption.

Simplest way is to use dimensions in % or em. Just change the base font size everything will change.

}


h5{

I came across this question while Googling for "git remove folder from tracking". The OP's question lead me to the answer. I am summarizing it here for future generations.

Question

How do I remove a folder from my git repository without deleting it from my local machine (i.e., development environment)?

Answer

Step 1. Add the folder path to your repo's root .gitignore file.

path_to_your_folder/

Step 2. Remove the folder from your local git tracking, but keep it on your disk.

git rm -r --cached path_to_your_folder/

Step 3. Push your changes to your git repo.

The folder will be considered "deleted" from Git's point of view (i.e. they are in past history, but not in the latest commit, and people pulling from this repo will get the files removed from their trees), but stay on your working directory because you've used --cached.

What about:

PrintWriter out = response.getWriter();
out.println("THE_STRING_TO_SEND_AS_RESPONSE");
return null;

This woks for me.

Execute SELECT 1 and check if ExecuteScalar returns 1.

First off, I use nvm on linux machine.

When looking at the documentation for nvm at https://www.npmjs.org/package/nvm, it recommendations that you install nvm globally using the -g switch.

npm install -g nvm

Also there is a . in the path variable that they recommend.

export PATH=./node_modules/.bin:$PATH

so maybe your path should be

C:\Program Files (x86)\nodejs\node_modules\npm\\.bin

This can be solved also by izipping the dataframe (iterator) with an offset version of itself.

Of course the indexing error cannot be reproduced this way.

Check this out

import pandas as pd
from itertools import izip

df = pd.DataFrame(['AA', 'BB', 'CC'], columns = ['value'])   

for id1, id2 in izip(df.iterrows(),df.ix[1:].iterrows()):
    print id1[1]['value']
    print id2[1]['value']

which gives

AA
BB
BB
CC

I found the answer I was looking for. The thing to use here is the construct of

\left \middle \right

For example, in this case, two possible solutions are:

$\left( {\frac{a_1}{a_2}} \middle/ {\frac{b_1}{b_2}} \right) $

Or, in case the brackets are not necessary:

$\left. {\frac{a_1}{a_2}} \middle/ {\frac{b_1}{b_2}} \right. $

I have changed a little bit previous answer and compose WPF version of the MessageBoxEx. This code works for me great. Feel free to notify about issues of the code.

Please note: I use GeneralObjects.MainWindowInstance at ctor to initialize class with my main window, but actually I use it for any window due to some kind of cache for last parent window. Therefore you can simple remove out everything from ctor.

public class MessageBoxEx

You could make the variables public fields:

  public int width;
  public int height;

  DrawFrame() {
    this.width = 400;
    this.height = 400;
  }

You could then access the variables like so:

DrawFrame frame = new DrawFrame();
int theWidth = frame.width;
int theHeight = frame.height;

A better solution, however, would be to make the variables private fields add two accessor methods to your class, keeping the data in the DrawFrame class encapsulated:

 private int width;
 private int height;

 DrawFrame() {
    this.width = 400;
    this.height = 400;
 }

  public int getWidth() {
     return this.width;
  }

  public int getHeight() {
     return this.height;
  }

Then you can get the width/height like so:

  DrawFrame frame = new DrawFrame();
  int theWidth = frame.getWidth();
  int theHeight = frame.getHeight();

I strongly suggest you use the latter method.

or Just %~F will give you the full path and full file name.

For example, if you want to register all *.ax files in the current directory....

FOR /R C:. %F in (*.ax) do regsvr32 "%~F"

This works quite nicely in Win7 (64bit) :-)

input.focus();

Or to html

One command in git that I think it's much easier to find a string:

git log --pretty=oneline --grep "string to search"

works in Git 2.0.4

This is supposed to print the ASCII value of the character, as %d is the escape sequence for an integer. So the value given as argument of printf is taken as integer when printed.

char ch = 'a';
printf("%d", ch);

Same holds for printf("%d", '\0');, where the NULL character is interpreted as the 0 integer.

Finally, sizeof('\n') is 4 because in C, this notation for characters stands for the corresponding ASCII integer. So '\n' is the same as 10 as an integer.

It all depends on the interpretation you give to the bytes.

This is how you can dynamically create a class named Child in your code, assuming Parent already exists... even if you don't have an explicit Parent class, you could use object...

The code below defines __init__() and then associates it with the class.

>>> child_name = "Child"
>>> child_parents = (Parent,)
>>> child body = """
def __init__(self, arg1):
    # Initialization for the Child class
    self.foo = do_something(arg1)
"""
>>> child_dict = {}
>>> exec(child_body, globals(), child_dict)
>>> childobj = type(child_name, child_parents, child_dict)
>>> childobj.__name__
'Child'
>>> childobj.__bases__
(<type 'object'>,)
>>> # Instantiating the new Child object...
>>> childinst = childobj()
>>> childinst
<__main__.Child object at 0x1c91710>
>>>

This is a server side issue. You don't need to add any headers in angular for cors. You need to add header on the server side:

Access-Control-Allow-Headers: Content-Type
Access-Control-Allow-Methods: GET, POST, OPTIONS
Access-Control-Allow-Origin: *

In my case, I was creating a framework with Cocoapods. The problems was this line:

s.static_framework = true

in my framework.podspec file

After commented this line above all problems to access storyboards or XIBs went out.

The with keywork is introduced in C# version 9! you can use it to create copy of object like follows

Person brother = person with { FirstName = "Paul" };

"The above line creates a new Person record where the LastName property is a copy of person, and the FirstName is "Paul". You can set any number of properties in a with-expression. Any of the synthesized members except the "clone" method may be written by you. If a record type has a method that matches the signature of any synthesized method, the compiler doesn't synthesize that method."

UPDATE:

At the time this answer is written, C#9 is not officially released but in preview only. However, it is planned to be shipped along with .NET 5.0 in November 2020

for more information, check the record types.

An array length is not the number of elements in a array, it is the highest index + 1. length property will report correct element count only if there are valid elements in consecutive indices.

var a = [];
a[23] = 'foo';
a.length;  // 24

Saying that, there is no way to exclude undefined elements from count without using any form of a loop.

I had the same issue and here is how I manage to pass through:

In your case you have addToCount() which is called. now to pass down a param when user clicks, you can say @click="addToCount(item.contactID)"

in your function implementation you can receive the params like:

addToCount(paramContactID){
 // the paramContactID contains the value you passed into the function when you called it
 // you can do what you want to do with the paramContactID in here!

}

    <li><span style="background-color:#b48ead"></span>Polar Area</li>
</ul>
</div>

To achieve this they use the chart configuration option legendTemplate

legendTemplate : "<ul class=\"<%=name.toLowerCase()%>-legend\"><% for (var i=0; i<segments.length; i++){%><li><span style=\"background-color:<%=segments[i].fillColor%>\"></span><%if(segments[i].label){%><%=segments[i].label%><%}%></li><%}%></ul>"

You can find the doumentation here on chartjs.org This works for all the charts although it is not part of the global chart configuration.

Then they create the legend and add it to the DOM like this:

var legend = myPie.generateLegend();
$("#legend").html(legend);

If you've already got underscore or lodash included in your project you can use _.sample.

// will return one item randomly from the array
_.sample(['January', 'February', 'March']);

If you need to get more than one item randomly, you can pass that as a second argument in underscore:

// will return two items randomly from the array using underscore
_.sample(['January', 'February', 'March'], 2);

or use the _.sampleSize method in lodash:

// will return two items randomly from the array using lodash
_.sampleSize(['January', 'February', 'March'], 2);

dim result as dialogresult
result = MessageBox.Show("message", "caption", MessageBoxButtons.YesNoCancel)
If result = DialogResult.Cancel Then
    MessageBox.Show("Cancel pressed")
ElseIf result = DialogResult.No Then
    MessageBox.Show("No pressed")
ElseIf result = DialogResult.Yes Then
    MessageBox.Show("Yes pressed")
End If

Late reaction, but I've struggled with this for a while so maybe I can save somebody some time by showing my solution.

My problem showed a bit different, but the cause might be the same.

In my situation, TortoiseSVN kept on trying to connect via a proxy server. I could access SVN via chrome, firefox and IE fine.

Turns out that there is a configuration file that has a different configuration than the GUI in TortoiseSVN shows.

Mine was located here: C:\Documents and Settings\[username]\Application Data\Subversion\, but you can also open the file via the TortoiseSVN gui.

In my file, http-proxy-exceptions was empty. After I specified it, everything worked fine.

[global]
http-proxy-exceptions = 10.1.1.11
http-proxy-host = 197.132.0.223
http-proxy-port = 8080
http-proxy-username = defaultusername
http-proxy-password = defaultpassword
http-compression = no

COPY description_f (id, name) FROM 'absolutepath\test.txt' WITH (FORMAT csv, HEADER true, DELIMITER '   ');

Example

COPY description_f (id, name) FROM 'D:\HIVEWORX\COMMON\TermServerAssets\Snomed2021\SnomedCT\Full\Terminology\sct2_Description_Full_INT_20210131.txt' WITH (FORMAT csv, HEADER true, DELIMITER ' ');

Do this instead:

<table width="100%" border="0" cellpadding="0" cellspacing="0">
  <tr>
      <td bgcolor="#7d9aaa" width="40%" style="color: #ffffff; font-size:15px; font-family:Arial, Helvetica, sans-serif; font-weight: bold; padding:12px;">
        Order Confirmation
      </td>
      <td bgcolor="#7d9aaa" align="right" width="60%" style="color: #ffffff; font-size:15px; font-family:Arial, Helvetica, sans-serif; font-weight: bold; padding:12px;">
        Your Confirmation number is {{var order.increment_id}}
      </td>
  </tr>
</table>

It is better to use two cells and align the content, than using large padding and  's.

First, thanks for the answers above! They lead to my solution.

I added this alias to my .bashrc file:

alias now='date +%Y-%m-%d-%H.%M.%S'

Now when I want to put a time stamp on a file such as a build log I can do this:

mvn clean install | tee build-$(now).log

and I get a file name like:

build-2021-02-04-03.12.12.log

As of now, you can only store string values in localStorage. You'll need to serialize the array object and then store it in localStorage.

For example:

localStorage.setItem('session', a.join('|'));

or

localStorage.setItem('session', JSON.stringify(a));

After trying to manually uninstall, and then downloading another copy of the VS 2015 community installer for use with the force uninstall command line argument (Original answer by Michael Schuchardt), I was still unable to modify the install directory.

After testing further, I found that Unity (which integrates with Visual Studio as of Unity 5.2) also had to be removed. At this point Visual Studio Uninstaller (link to latest release on Github) can be used for the final removal of remaining any remaining components.

You will now be able to run the Visual Studio Installer and select a directory or, alternatively, run the install from command line using the "/CustomInstallPath ..." argument.

I'm not entirely sure but I think you are probably surprised at how arrays are serialized in JSON. Let's isolate the problem. Consider following code:

var display = Array();
display[0] = "none";
display[1] = "block";
display[2] = "none";

console.log( JSON.stringify(display) );

This will print:

["none","block","none"]

This is how JSON actually serializes array. However what you want to see is something like:

{"0":"none","1":"block","2":"none"}

To get this format you want to serialize object, not array. So let's rewrite above code like this:

var display2 = {};
display2["0"] = "none";
display2["1"] = "block";
display2["2"] = "none";

console.log( JSON.stringify(display2) );

This will print in the format you want.

You can play around with this here: http://jsbin.com/oDuhINAG/1/edit?js,console

Use self.view.tintColor from a view controller, or self.tintColor from a UIView subclass.

I believe using --no-index is what you're looking for:

git diff [<options>] --no-index [--] <path> <path>

as mentioned in the git manual:

This form is to compare the given two paths on the filesystem. You can omit the --no-index option when running the command in a working tree controlled by Git and at least one of the paths points outside the working tree, or when running the command outside a working tree controlled by Git.

Data Storage:

• Specify the utf8mb4 character set on all tables and text columns in your database. This makes MySQL physically store and retrieve values encoded natively in UTF-8. Note that MySQL will implicitly use utf8mb4 encoding if a utf8mb4_* collation is specified (without any explicit character set).

• In older versions of MySQL (< 5.5.3), you'll unfortunately be forced to use simply utf8, which only supports a subset of Unicode characters. I wish I were kidding.

Data Access:

• In your application code (e.g. PHP), in whatever DB access method you use, you'll need to set the connection charset to utf8mb4. This way, MySQL does no conversion from its native UTF-8 when it hands data off to your application and vice versa.

• Some drivers provide their own mechanism for configuring the connection character set, which both updates its own internal state and informs MySQL of the encoding to be used on the connection—this is usually the preferred approach. In PHP:

  • If you're using the PDO abstraction layer with PHP = 5.3.6, you can specify charset in the DSN:

     $dbh = new PDO('mysql:charset=utf8mb4');
    

  • If you're using mysqli, you can call set_charset():

      $mysqli->set_charset('utf8mb4');       // object oriented style
      mysqli_set_charset($link, 'utf8mb4');  // procedural style
    

  • If you're stuck with plain mysql but happen to be running PHP = 5.2.3, you can call mysql_set_charset.

• If the driver does not provide its own mechanism for setting the connection character set, you may have to issue a query to tell MySQL how your application expects data on the connection to be encoded: SET NAMES 'utf8mb4'.

• The same consideration regarding utf8mb4/utf8 applies as above.

Output:

• If your application transmits text to other systems, they will also need to be informed of the character encoding. With web applications, the browser must be informed of the encoding in which data is sent (through HTTP response headers or HTML metadata).

• In PHP, you can use the default_charset php.ini option, or manually issue the Content-Type MIME header yourself, which is just more work but has the same effect.

• When encoding the output using json_encode(), add JSON_UNESCAPED_UNICODE as a second parameter.

Input:

• Unfortunately, you should verify every received string as being valid UTF-8 before you try to store it or use it anywhere. PHP's mb_check_encoding() does the trick, but you have to use it religiously. There's really no way around this, as malicious clients can submit data in whatever encoding they want, and I haven't found a trick to get PHP to do this for you reliably.

• From my reading of the current HTML spec, the following sub-bullets are not necessary or even valid anymore for modern HTML. My understanding is that browsers will work with and submit data in the character set specified for the document. However, if you're targeting older versions of HTML (XHTML, HTML4, etc.), these points may still be useful:

  • For HTML before HTML5 only: you want all data sent to you by browsers to be in UTF-8. Unfortunately, if you go by the only way to reliably do this is add the accept-charset attribute to all your <form> tags: <form ... accept-charset="UTF-8">.
  • For HTML before HTML5 only: note that the W3C HTML spec says that clients "should" default to sending forms back to the server in whatever charset the server served, but this is apparently only a recommendation, hence the need for being explicit on every single <form> tag.

Other Code Considerations:

• Obviously enough, all files you'll be serving (PHP, HTML, JavaScript, etc.) should be encoded in valid UTF-8.

• You need to make sure that every time you process a UTF-8 string, you do so safely. This is, unfortunately, the hard part. You'll probably want to make extensive use of PHP's mbstring extension.

• PHP's built-in string operations are not by default UTF-8 safe. There are some things you can safely do with normal PHP string operations (like concatenation), but for most things you should use the equivalent mbstring function.

• To know what you're doing (read: not mess it up), you really need to know UTF-8 and how it works on the lowest possible level. Check out any of the links from utf8.com for some good resources to learn everything you need to know.

from https://docs.angularjs.org/api/ng/function/angular.element

angular.element

wraps a raw DOM element or HTML string as a jQuery element (If jQuery is not available, angular.element delegates to Angular's built-in subset of jQuery, called "jQuery lite" or "jqLite.")

So you simply could do:

angular.module('myApp.filters', []).
  filter('htmlToPlaintext', function() {
    return function(text) {
      return angular.element(text).text();
    }
  }
);

Usage:

<div>{{myText | htmlToPlaintext}}</div>

If you are running as a user with administrator rights then environment variable SessionName will NOT be defined and you still don't have administrator rights when running a batch file.

You should use "net session" command and look for an error return code of "0" to verify administrator rights.

Example; - the first echo statement is the bell character net session >nul 2>&1 if not %errorlevel%==0 (echo echo You need to start over and right-click on this file, echo then select "Run as administrator" to be successfull. echo.&pause&exit)

There are different approaches. If you want to do this from remote, issue flushall to that instance, through command line tool redis-cli or whatever tools i.e. telnet, a programming language SDK. Or just log in that server, kill the process, delete its dump.rdb file and appendonly.aof(backup them before deletion).

Following solution worked for me. When connecting to the db, specify that data should be truncated if they are too long (jdbcCompliantTruncation). My link looks like this:

jdbc:mysql://SERVER:PORT_NO/SCHEMA?sessionVariables=sql_mode='NO_ENGINE_SUBSTITUTION'&jdbcCompliantTruncation=false

If you increase the size of the strings, you may face the same problem in future if the string you are attempting to store into the DB is longer than the new size.

EDIT: STRICT_TRANS_TABLES has to be removed from sql_mode as well.

There is a library called NineOldAndroids, which allows you to use the Honeycomb animation library all the way down to version one.

This means you can define left, right, translationX/Y with a slightly different interface.

Here is how it works:

ViewHelper.setTranslationX(view, 50f);

You just use the static methods from the ViewHelper class, pass the view and which ever value you want to set it to.

Here is a tidyverse option that might not the most elegant, but offers some flexibility in terms of what is included in the summary:

library(tidyverse)
dir_path <- '~/path/to/data/directory/'
file_pattern <- 'Df\\.[0-9]\\.csv' # regex pattern to match the file name format

read_dir <- function(dir_path, file_name){
  read_csv(paste0(dir_path, file_name)) %>% 
    mutate(file_name = file_name) %>%                # add the file name as a column              
    gather(variable, value, A:B) %>%                 # convert the data from wide to long
    group_by(file_name, variable) %>% 
    summarize(sum = sum(value, na.rm = TRUE),
              min = min(value, na.rm = TRUE),
              mean = mean(value, na.rm = TRUE),
              median = median(value, na.rm = TRUE),
              max = max(value, na.rm = TRUE))
  }

df_summary <- 
  list.files(dir_path, pattern = file_pattern) %>% 
  map_df(~ read_dir(dir_path, .))

Try to add empty View inside horizontal LinearLayout before element that you want to see right, e.g.:

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >

    <View
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:layout_weight="1" />                

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</LinearLayout>

            //                                              );

            //Set array of number variants
            $numbers    =   array ( 'original' => $matchset[0],
                                        'stripped' => substr(preg_replace('[\D]', '', $matchset[0]), 0, 10)
                                        );

            //Now let's check the first ten digits against NANPA standards
            if(preg_match($nanpa_pattern, $numbers['stripped'])) {
                $valid['nanpa'] = true;
            }

            //If the NANPA guidelines have been met, continue
            if ( $valid['nanpa'] ) {
                if ( !empty ( $components['xn'] ) ) {
                    if ( preg_match ( '/^[\d]{1,6}$/', $components['xn'] ) ) {
                        $valid['ext'] = true;
                    }   // end if if preg_match 
                } else {
                    $valid['ext'] = true;
                }   // end if if  !empty
            }   // end if $valid nanpa

            //If the extension number is valid or non-existent, continue
            if ( $valid['ext'] ) {
                $valid['all'] = true;
            }   // end if $valid ext
        }   // end if $valid
        return $valid['all'];
    }   // end functon validate_phone_number

Notice I have this in a class lib, so thus the "self::validate_phone_number" call from the first function/method.

Notice line # 32 of the "validate_phone_number" function where I added the:

            if ( !$valid['format'] ) {
            return false;
        } else {

to get me the false return needed if not valid phone number.

Still need to test this against more data, but working on current data, with current format and I'm using style '8' for this particular data batch.

Also I commented out the "extension" logic as I was constantly getting errors from it, seeing I do not have any of that info in my data.

Please make sure that all properties are both the getter and setter. In case, any property is getter only, it will cause the reverting the List to original data as the JSON string is typed.

Please refer to the following code snippet for the same: Model:

 public class Person
{
    public int ID { get; set; }
    // following 2 lines are cause of error
    //public string Name { get { return string.Format("{0} {1}", First, Last); } }
    //public string Country { get { return Countries[CountryID]; } }
    public int CountryID { get; set; }
    public bool Active { get; set; }
    public string First { get; set; }
    public string Last { get; set; }
    public DateTime Hired { get; set; }
}
public class ModelObj
    {
        public string Str { get; set; }
        public List<Person> Persons { get; set; }
    }

Controller:

 [HttpPost]
    public ActionResult Index(FormCollection collection)
    {
        var data = new ModelObj();
        data.Str = (string)collection.GetValue("Str").ConvertTo(typeof(string));
        var personsString = (string)collection.GetValue("Persons").ConvertTo(typeof(string));
        using (var textReader = new StringReader(personsString))
        {
            using (var reader = new JsonTextReader(textReader))
            {
                data.Persons = new JsonSerializer().Deserialize(reader, typeof(List<Person>)) as List<Person>; 
            }
        }

        return View(data);
    }

The following code works fine:

@using (Html.BeginForm("Upload", "Upload", FormMethod.Post, 
                                      new { enctype = "multipart/form-data" }))
{
    @Html.ValidationSummary(true)
    <fieldset>
        Select a file <input type="file" name="file" />
        <input type="submit" value="Upload" />
    </fieldset>
}

and generates as expected:

<form action="/Upload/Upload" enctype="multipart/form-data" method="post">    
    <fieldset>
        Select a file <input type="file" name="file" />
        <input type="submit" value="Upload" />
    </fieldset>
</form>

On the other hand if you are writing this code inside the context of other server side construct such as an if or foreach you should remove the @ before the using. For example:

@if (SomeCondition)
{
    using (Html.BeginForm("Upload", "Upload", FormMethod.Post, 
                                      new { enctype = "multipart/form-data" }))
    {
        @Html.ValidationSummary(true)
        <fieldset>
            Select a file <input type="file" name="file" />
            <input type="submit" value="Upload" />
        </fieldset>
    }
}

As far as your server side code is concerned, here's how to proceed:

[HttpPost]
public ActionResult Upload(HttpPostedFileBase file) 
{
    if (file != null && file.ContentLength > 0) 
    {
        var fileName = Path.GetFileName(file.FileName);
        var path = Path.Combine(Server.MapPath("~/content/pics"), fileName);
        file.SaveAs(path);
    }
    return RedirectToAction("Upload");
}

Now Microsoft is migrating to open-source - see CoreFX (GitHub).

I find that there are 3 package-based solutions to solve the problem. They are pyenchant, wordnet and corpus(self-defined or from ntlk). Pyenchant couldn't installed easily in win64 with py3. Wordnet doesn't work very well because it's corpus isn't complete. So for me, I choose the solution answered by @Sadik, and use 'set(words.words())' to speed up.

First:

pip3 install nltk
python3

import nltk
nltk.download('words')

Then:

from nltk.corpus import words
setofwords = set(words.words())

print("hello" in setofwords)
>>True

Here's the mysql reference for cursors. So I'm guessing it's something like this:

  DECLARE done INT DEFAULT 0;
  DECLARE products_id INT;
  DECLARE result varchar(4000);
  DECLARE cur1 CURSOR FOR SELECT products_id FROM sets_products WHERE set_id = 1;
  DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = 1;

  OPEN cur1;

  REPEAT
    FETCH cur1 INTO products_id;
    IF NOT done THEN
      CALL generate_parameter_list(@product_id, @result);
      SET param = param + "," + result; -- not sure on this syntax
    END IF;
  UNTIL done END REPEAT;

  CLOSE cur1;

  -- now trim off the trailing , if desired

Use .toInt() for int .toFloat() for float and .toDouble() for double

toInt();

Have you tried escaping the dot? like this:

String[] words = line.split("\\.");

Router Link

routerLink with brackets and none - simple explanation.

The difference between routerLink= and [routerLink] is mostly like relative and absolute path.

Similar to a href you may want to navigate to ./about.html or https://your-site.com/about.html.

When you use without brackets then you navigate relative and without params;

my-app.com/dashboard/client

"jumping" from my-app.com/dashboard to my-app.com/dashboard/client

<a routerLink="client/{{ client.id }}" .... rest the same

When you use routerLink with brackets then you execute app to navigate absolute and you can add params how is the puzzle of your new link

first of all it will not include the "jump" from dashboard/ to dashboard/client/client-id and bring you data of client/client-id which is more helpful for EDIT CLIENT

<a [routerLink]="['/client', client.id]" ... rest the same

The absolute way or brackets routerLink require additional set up of you components and app.routing.module.ts

The code without error will "tell you more/what is the purpose of []" when you make the test. Just check this with or without []. Than you may experiments with selectors which - as mention above - helps with dynamics routing.

Angular.io Selectors

See whats the routerLink construct

https://angular.io/api/router/RouterLink#selectors

Variables are available only in the scope you defined them. If you define a variable inside a function, you won't be able to access it outside of it.

Define variable with var outside the function (and of course before it) and then assign 10 to it inside function:

var value;
$(function() {
  value = "10";
});
console.log(value); // 10

Note that you shouldn't omit the first line in this code (var value;), because otherwise you are assigning value to undefined variable. This is bad coding practice and will not work in strict mode. Defining a variable (var variable;) and assigning value to a variable (variable = value;) are two different things. You can't assign value to variable that you haven't defined.

It might be irrelevant here, but $(function() {}) is a shortcut for $(document).ready(function() {}), which executes a function as soon as document is loaded. If you want to execute something immediately, you don't need it, otherwise beware that if you run it before DOM has loaded, value will be undefined until it has loaded, so console.log(value); placed right after $(function() {}) will return undefined. In other words, it would execute in following order:

var value;
console.log(value);
value = "10";

I had the same error, but while I was connected and other previous statements in a script ran fine before! (So the connection was already open and some successful statements ran fine in auto-commit mode) The error was reproducable for some minutes. Then it had just disappeared. I don't know if somebody or some internal mechanism did some maintenance work or similar within this time - maybe.

Developing New Code

Debugging inside IPython

1. Use Jupyter/IPython cell execution to speed up experiment iterations
2. Use %%debug for step through

Cell Example:

%%debug
...: for n in range(4):
...:    n>2

Debugging Existing Code

IPython inside debugging

1. Debugging a broken unit test: pytest ... --pdbcls=IPython.terminal.debugger:TerminalPdb --pdb
2. Debugging outside of test case: breakpoint(), python -m ipdb, etc.
3. IPython.embed() for full IPython functionality where needed while in the debugger

Thoughts on Python

I agree with the OP that many things MATLAB does nicely Python still does not have and really should since just about everything in the language favors development speed over production speed. Maybe someday I will contribute more than trivial bug fixes to CPython.

Simply use this

echo date('Y-m-d',strtotime("yesterday"));
echo date('Y-m-d',strtotime("tomorrow"));

After using session_destroy(), the session is destroyed behind the scenes. For some reason this doesn't affect the values in $_SESSION, which was already populated for this request, but it will be empty in future requests.

You can manually clear $_SESSION if you so desire ($_SESSION = [];).

Use mongoexport/mongoimport to dump/restore a collection:

Export JSON File:

mongoexport --db <database-name> --collection <collection-name> --out output.json

Import JSON File:

mongoimport --db <database-name> --collection <collection-name> --file input.json

WARNING mongoimport and mongoexport do not reliably preserve all rich BSON data types because JSON can only represent a subset of the types supported by BSON. As a result, data exported or imported with these tools may lose some measure of fidelity.

Also, http://bsonspec.org/

BSON is designed to be fast to encode and decode. For example, integers are stored as 32 (or 64) bit integers, so they don't need to be parsed to and from text. This uses more space than JSON for small integers, but is much faster to parse.

In addition to compactness, BSON adds additional data types unavailable in JSON, notably the BinData and Date data types.

As an alternative to the previous answers, guava's Splitter API can be used if other operations are to be applied to the resulting lines, like trimming lines or filtering empty lines :

import com.google.common.base.Splitter;

Iterable<String> split = Splitter.onPattern("\r?\n").trimResults().omitEmptyStrings().split(docStr);

Note that the result is an Iterable and not an array.

If you want a css only solution you can use active

.crossRotate:active {
   transform: rotate(45deg);
   -webkit-transform: rotate(45deg);
   -ms-transform: rotate(45deg);
}

But the transformation will not persist when the activity moves. For that you need javascript (jquery click and css is the cleanest IMO).

$( ".crossRotate" ).click(function() {
    if (  $( this ).css( "transform" ) == 'none' ){
        $(this).css("transform","rotate(45deg)");
    } else {
        $(this).css("transform","" );
    }
});

terrific answer from DuckPuncher, for Python3 make sure you install pdfminer2 and do:

import io

from pdfminer.pdfinterp import PDFResourceManager, PDFPageInterpreter
from pdfminer.converter import TextConverter
from pdfminer.layout import LAParams
from pdfminer.pdfpage import PDFPage


def convert_pdf_to_txt(path):
    rsrcmgr = PDFResourceManager()
    retstr = io.StringIO()
    codec = 'utf-8'
    laparams = LAParams()
    device = TextConverter(rsrcmgr, retstr, codec=codec, laparams=laparams)
    fp = open(path, 'rb')
    interpreter = PDFPageInterpreter(rsrcmgr, device)
    password = ""
    maxpages = 0
    caching = True
    pagenos = set()

    for page in PDFPage.get_pages(fp, pagenos, maxpages=maxpages,
                                  password=password,
                                  caching=caching,
                                  check_extractable=True):
        interpreter.process_page(page)



    fp.close()
    device.close()
    text = retstr.getvalue()
    retstr.close()
    return text

Well, Pavel was close, but there's even a more simple and elegant solution to initialize a sequential container from a c style array.

In your case:

w_ (array, std::end(array))

• array will get us a pointer to the beginning of the array (didn't catch it's name),
• std::end(array) will get us an iterator to the end of the array.

We are also getting the same error while we are trying to access a same resource with in milliseconds. Like if i try to POST some data to www.abc.com/blog and with in milliseconds an other request will also go for the same resource i.e. www.abc.com/blog from the same user. So it'll give the 409 error.

You can use an ArrayList and then use the toArray() method. But depending on what you are doing, you might not even need an array at all. Look into seeing if Lists are more what you want.

See: Java List Tutorial

You can encode the < and > to their HTML equivelant.

html = html.replace(/</g, "&lt;").replace(/>/g, "&gt;");

How to display HTML tags as plain text

use the click event for best compatibility with MSIE

$(document).ready(function() {
    $("input[type=checkbox]").click(function() {
        alert("state changed");
    });
});

I had this one a while back, and the answer isn't necessarily what you'd expect. This error message often crops up when your connection string is wrong.

At a guess, you'll need something like this:

<connectionStrings>
    <add name="hublisherEntities" connectionString="Data Source=localhost;Initial Catalog=hublisher;Integrated Security=True;" providerName="System.Data.SqlClient" />
</connectionStrings>
<entityFramework>
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework">
        <parameters>
            <parameter value="Data Source=localhost;Initial Catalog=hublisher;Integrated Security=True" />
        </parameters>
    </defaultConnectionFactory>
</entityFramework>

What's happening is that it's looking for a data source in the wrong place; Entity Framework specifies it slightly differently. If you post your connection string and EF config then we can check.

You can use PowerMockito

See the example:

Second second = Mockito.mock(Second.class);
whenNew(Second.class).withNoArguments().thenReturn(second);

But re-factoring is better decision.

You're actually in luck - the program writing the file locks it, so you can't open it. If it hadn't locked it, you would have copied a partial file, without having any idea there's a problem.

When you can't access a file, you can assume it's still in use (better yet - try to open it in exclusive mode, and see if someone else is currently opening it, instead of guessing from the failure of File.Copy). If the file is locked, you'll have to copy it at some other time. If it's not locked, you can copy it (there's slight potential for a race condition here).

When is that 'other time'? I don't rememeber when FileSystemWatcher sends multiple events per file - check it out, it might be enough for you to simply ignore the event and wait for another one. If not, you can always set up a time and recheck the file in 5 seconds.

OPTION 1: Add this line to ~/.zshrc:

export "PATH=$HOME/pear/bin:$PATH"

After that you need to run source ~/.zshrc in order your changes to take affect OR close this window and open a new one

OPTION 2: execute it inside the terminal console to add this path only to the current terminal window session. When you close the window/session, it will be lost.

You can simply do :-

{{"<li>Something</li>".repeat(5)}}

When you put empty action then some security filtration consider it malicious or phishing. Hence they can block your page. So its advisable not to keep action= blank.

You don't mention the API version, but since API 11 there's the method WebViewClient.shouldInterceptRequest

Maybe this could help?

Most common case of this error happening is using template that is generating the control then changing the way id and/or nameare being generated by 'overriding' default template with something like

@Html.TextBoxFor(m => m, new {Name = ViewData["Name"], id = ViewData["UniqueId"]} )

and then forgetting to change ValidationMessageFor to

@Html.ValidationMessageFor(m => m, null, new { data_valmsg_for = ViewData["Name"] })    

Hope this saves you some time.

A clone is simply a copy of a repository. On the surface, its result is equivalent to svn checkout, where you download source code from some other repository. The difference between centralized VCS like Subversion and DVCSs like Git is that in Git, when you clone, you are actually copying the entire source repository, including all the history and branches. You now have a new repository on your machine and any commits you make go into that repository. Nobody will see any changes until you push those commits to another repository (or the original one) or until someone pulls commits from your repository, if it is publicly accessible.

A branch is something that is within a repository. Conceptually, it represents a thread of development. You usually have a master branch, but you may also have a branch where you are working on some feature xyz, and another one to fix bug abc. When you have checked out a branch, any commits you make will stay on that branch and not be shared with other branches until you merge them with or rebase them onto the branch in question. Of course, Git seems a little weird when it comes to branches until you look at the underlying model of how branches are implemented. Rather than explain it myself (I've already said too much, methinks), I'll link to the "computer science" explanation of how Git models branches and commits, taken from the Git website:

http://eagain.net/articles/git-for-computer-scientists/

A fork isn't a Git concept really, it's more a political/social idea. That is, if some people aren't happy with the way a project is going, they can take the source code and work on it themselves separate from the original developers. That would be considered a fork. Git makes forking easy because everyone already has their own "master" copy of the source code, so it's as simple as cutting ties with the original project developers and doesn't require exporting history from a shared repository like you might have to do with SVN.

EDIT: since I was not aware of the modern definition of "fork" as used by sites such as GitHub, please take a look at the comments and also Michael Durrant's answer below mine for more information.

Based on a Graphviz script I found in an answer to a related question, I've hacked up a ruby script that creates a summary view of a git repository. It elides all linear history and just shows "interesting" commits, i.e. those with multiple parents, multiple children, or pointed to by a branch or tag. Here's a snippet of the graph it generates for jquery:

git-big-picture and BranchMaster are similar tools that try to show only the high-level structure of a graph, by only displaying how tags, branches, merges, etc. are related.

This question has some more options.

This worked for me. Make sure Gradle is not set to offline by unchecking button at File>Settings>Gradle>Offline Work.

Add this to the top level of your build.gradle, nice to have above dependencies

configurations.all {
    resolutionStrategy.cacheChangingModulesFor 0, 'seconds'
}

I made sure my dependencies are written like this:

implementation('com.github.juanmendez:ThatDependency:ThatBranch-SNAPSHOT') {
    changing = true
}

Thereafter, I open the Gradle panel in Android Studio and click the blue circle arrows button. I can always see my updates getting a new fresh copy.

If you want to translate your resources, just download MAT (Multilingual App Toolkit) for Visual Studio. https://marketplace.visualstudio.com/items?itemName=MultilingualAppToolkit.MultilingualAppToolkit-18308 This is the way to go to translate your projects in Visual Studio. https://blogs.msdn.microsoft.com/matdev/

It's not the best way to deal with the issue above. But it's an alternative one...

while (Directory.GetDirectories(dirpath).Length > 0)
 {
       //Delete all files in directory
       while (Directory.GetFiles(Directory.GetDirectories(dirpath)[0]).Length > 0)
       {
            File.Delete(Directory.GetFiles(dirpath)[0]);
       }
       Directory.Delete(Directory.GetDirectories(dirpath)[0]);
 }

Note: I am not happy with previous answers, (not working on all systems, not working on remote, not specifying the --merged branch, not filtering exactly). So, I add my own answer.

There are two main cases:

Local

You want to delete local branches that are already merged to another local branch. During the deletion, you want to keep some important branches, like master, develop, etc.

git branch --format "%(refname:short)" --merged master | grep -E -v '^master$|^feature/develop$' | xargs -n 1 git branch -d

Notes:

• git branch output --format ".." is to strip whitespaces and allow exact grep matching
• grep -E is used instead of egrep, so it works also in systems without egrep (i.e.: git for windows).
• grep -E -v '^master$|^feature/develop$' is to specify local branches that I don't want to delete
• xargs -n 1 git branch -d: perform the deletion of local branches (it won't work for remote ones)
• of course you get an error if you try deleting the branch currently checked-out. So, I suggest to switch to master beforehand.

Remote

You want to delete remote branches that are already merged to another remote branch. During the deletion, you want to keep some important branches, like HEAD, master, releases, etc.

git branch -r --format "%(refname:short)" --merged origin/master | grep -E -v '^*HEAD$|^*/master$|^*release' | cut -d/ -f2- | xargs -n 1 git push --delete origin

Notes:

• for remote, we use the -r option and provide the full branch name: origin/master
• grep -E -v '^*HEAD$|^*/master$|^*release' is to match the remote branches that we don't want to delete.
• cut -d/ -f2- : remove the unneeded 'origin/' prefix that otherwise is printed out by the git branch command.
• xargs -n 1 git push --delete origin : perform the deletion of remote branches.

In my case, Python was unable to find it because I'd put the code inside a module with hyphens, e.g. my-module. When I changed it to my_module it worked.

Replace hidden with none. See MDN reference.

Without Random solution:

   static void randomArrTimest(int[] some){
        long startTime = System.currentTimeMillis();
        for (int i = 0; i < some.length; i++) {
            long indexToSwap = startTime%(i+1);
            long tmp = some[(int) indexToSwap];
            some[(int) indexToSwap] = some[i];
            some[i] = (int) tmp;
        }
        System.out.println(Arrays.toString(some));
    }

please try this to clean and format your column names:

df.columns = (df.columns.str.strip().str.upper()
              .str.replace(' ', '_')
              .str.replace('(', '')
              .str.replace(')', ''))

If your working directory points to the trunk, then you should be able to merge your branch with:

svn merge https://HOST/repository/branches/branch_1

be sure to be to issue this command in the root directory of your trunk

Please note that both the HTML5 specification of W3C and WhatWG standardize

<link rel="icon" href="/favicon.ico">

Note the value of the "rel" attribute!

The value shortcut icon for the rel attribute is a very old Internet Explorer specific extension and deprecated.

So please consider not using it any more and updating your files so they are standards compliant and are displayed correctly in all browsers.

You might also want to take a look at this great post: rel="shortcut icon" considered harmful

I don't know of any built-in way to do this. However, it would seem easy enough to do, since the only delimiters you have to worry about are the newline character and the equals sign.

It would be very easy to write a routine that will return a NameValueCollection, or an IDictionary given the contents of the file.

This is mainly for future readers. As the question (at least the title) focuses on "connecting to sql server database from node js", I would like to chip in about "mssql" node module.

At this moment, we have a stable version of Microsoft SQL Server driver for NodeJs ("msnodesql") available here: https://www.npmjs.com/package/msnodesql. While it does a great job of native integration to Microsoft SQL Server database (than any other node module), there are couple of things to note about.

"msnodesql" require a few pre-requisites (like python, VC++, SQL native client etc.) to be installed on the host machine. That makes your "node" app "Windows" dependent. If you are fine with "Windows" based deployment, working with "msnodesql" is the best.

On the other hand, there is another module called "mssql" (available here https://www.npmjs.com/package/mssql) which can work with "tedious" or "msnodesql" based on configuration. While this module may not be as comprehensive as "msnodesql", it pretty much solves most of the needs.

If you would like to start with "mssql", I came across a simple and straight forward video, which explains about connecting to Microsoft SQL Server database using NodeJs here: https://www.youtube.com/watch?v=MLcXfRH1YzE

Source code for the above video is available here: http://techcbt.com/Post/341/Node-js-basic-programming-tutorials-videos/how-to-connect-to-microsoft-sql-server-using-node-js

Just in case, if the above links are not working, I am including the source code here:

var sql = require("mssql");_x000D_

    _x000D_
    conn.connect().then(function () {_x000D_
        var req = new sql.Request(conn);_x000D_
        req.query("SELECT * FROM emp").then(function (recordset) {_x000D_
            console.log(recordset);_x000D_
            conn.close();_x000D_

    .catch(function (err) {_x000D_
        console.log(err);_x000D_
    });_x000D_
_x000D_
    //--> another way_x000D_
    //var req = new sql.Request(conn);_x000D_
    //conn.connect(function (err) {_x000D_
    //    if (err) {_x000D_
    //        console.log(err);_x000D_
    //        return;_x000D_
    //    }_x000D_
    //    req.query("SELECT * FROM emp", function (err, recordset) {_x000D_

    //        }_x000D_
    //        else { _x000D_
    //            console.log(recordset);_x000D_
    //        }_x000D_
    //        conn.close();_x000D_
    //    });_x000D_
    //});_x000D_
_x000D_
}_x000D_
_x000D_
getEmp();

The above code is pretty self explanatory. We define the db connection parameters (in "dbConfig" JS object) and then use "Connection" object to connect to SQL Server. In order to execute a "SELECT" statement, in this case, it uses "Request" object which internally works with "Connection" object. The code explains both flavors of using "promise" and "callback" based executions.

The above source code explains only about connecting to sql server database and executing a SELECT query. You can easily take it to the next level by following documentation of "mssql" node available at: https://www.npmjs.com/package/mssql

UPDATE: There is a new video which does CRUD operations using pure Node.js REST standard (with Microsoft SQL Server) here: https://www.youtube.com/watch?v=xT2AvjQ7q9E. It is a fantastic video which explains everything from scratch (it has got heck a lot of code and it will not be that pleasing to explain/copy the entire code here)

Run command rndc querylog on or add querylog yes; to options{}; section in named.conf to activate that channel.

Remove all your httpclient, httpmime dependency and add this dependency compile 'commons-httpclient:commons-httpclient:3.1'. This dependency has built in MultipartRequestEntity so that you can easily upload one or more files to the server

public class FileUploadUrlConnection extends AsyncTask<String, String, String> {
private Context context;
private String url;
private List<File> files;

public FileUploadUrlConnection(Context context, String url, List<File> files) {
    this.context = context;
    this.url = url;
    this.files = files;
}

@Override
protected String doInBackground(String... params) {

    HttpClient client = new HttpClient();
    PostMethod post = new PostMethod(url);
    HttpClientParams connectionParams = new HttpClientParams();

    post.setRequestHeader(// Your header goes here );

    try {
        Part[] parts = new Part[files.size()];
        for (int i=0; i<files.size(); i++) {
            Part part = new FilePart(files.get(i).getName(), files.get(i));
            parts[i] = part;
        }

        MultipartRequestEntity entity = new MultipartRequestEntity(parts, connectionParams);

        post.setRequestEntity(entity);

        int statusCode = client.executeMethod(post);
        String response = post.getResponseBodyAsString();

        Log.v("Multipart "," "+response);
        if(statusCode == 200) {
            return response;
        }
    } catch (IOException e) {
        e.printStackTrace();
    } 
 return null;
}

You can also add the request and response timeout

client.getParams().setParameter(CoreConnectionPNames.CONNECTION_TIMEOUT, 10000);
client.getParams().setParameter(CoreConnectionPNames.SO_TIMEOUT, 10000);

Try this once and make sure you are not getting any error in project Structure saying that "ComGoogleAndroidGmsPlay not added"

Open File > Project Structure and check for below all. If error is shown click on Red bulb marked and click on "Add to dependency".

This is a bug in Android Studio and fixed for the next release(0.4.3)

According to the latest pandas documentation you can read a csv file selecting only the columns which you want to read.

import pandas as pd

df = pd.read_csv('some_data.csv', usecols = ['col1','col2'], low_memory = True)

Here we use usecols which reads only selected columns in a dataframe.

We are using low_memory so that we Internally process the file in chunks.

I have solved this error. You just need to add layout manager and add the empty adapter.

Like this code:

myRecyclerView.setLayoutManager(...//your layout manager);
        myRecyclerView.setAdapter(new RecyclerView.Adapter() {
            @Override
            public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
                return null;
            }

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

            }

            @Override
            public int getItemCount() {
                return 0;
            }
        });
//other code's 
// and for change you can use if(mrecyclerview.getadapter != speacialadapter){
//replice your adapter
//}

A submodule may be marked as dirty if filemode settings is enabled and you changed file permissions in submodule subtree.

To disable filemode in a submodule, you can edit /.git/modules/path/to/your/submodule/config and add

[core]
  filemode = false

If you want to ignore all dirty states, you can either set ignore = dirty property in /.gitmodules file, but I think it's better to only disable filemode.

How about the simple way of

for (var i = 0; i < n; i++) {
 sum = sum + Int(multiples[i])!
}

//where n = number of elements in the array

I would expect that the JVM gracefully interrupts (thread.interrupt()) all the running threads created by the application, at least for signals SIGINT (kill -2) and SIGTERM (kill -15).

This way, the signal will be forwarded to them, allowing a gracefully thread cancellation and resource finalization in the standard ways.

But this is not the case (at least in my JVM implementation: Java(TM) SE Runtime Environment (build 1.8.0_25-b17), Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode).

As other users commented, the usage of shutdown hooks seems mandatory.

So, how do I would handle it?

Well first, I do not care about it in all programs, only in those where I want to keep track of user cancellations and unexpected ends. For example, imagine that your java program is a process managed by other. You may want to differentiate whether it has been terminated gracefully (SIGTERM from the manager process) or a shutdown has occurred (in order to relaunch automatically the job on startup).

As a basis, I always make my long-running threads periodically aware of interrupted status and throw an InterruptedException if they interrupted. This enables execution finalization in way controlled by the developer (also producing the same outcome as standard blocking operations). Then, at the top level of the thread stack, InterruptedException is captured and appropriate clean-up performed. These threads are coded to known how to respond to an interruption request. High cohesion design.

So, in these cases, I add a shutdown hook, that does what I think the JVM should do by default: interrupt all the non-daemon threads created by my application that are still running:

Runtime.getRuntime().addShutdownHook(new Thread() {
    @Override
    public void run() {
        System.out.println("Interrupting threads");
        Set<Thread> runningThreads = Thread.getAllStackTraces().keySet();
        for (Thread th : runningThreads) {
            if (th != Thread.currentThread() 
                && !th.isDaemon() 
                && th.getClass().getName().startsWith("org.brutusin")) {
                System.out.println("Interrupting '" + th.getClass() + "' termination");
                th.interrupt();
            }
        }
        for (Thread th : runningThreads) {
            try {
                if (th != Thread.currentThread() 
                && !th.isDaemon() 
                && th.isInterrupted()) {
                    System.out.println("Waiting '" + th.getName() + "' termination");
                    th.join();
                }
            } catch (InterruptedException ex) {
                System.out.println("Shutdown interrupted");
            }
        }
        System.out.println("Shutdown finished");
    }
});

One option is to get out of the php block and just write HTML.

With your code, after the opening curly brace of your if statement, end the PHP:

if (is_single()) { ?>

Then remove the echo ' and the ';

After all your html and css, before the closing }, write:

<? } else {

If the text you want to write to the page is dynamic, it gets a little trickier, but for now this should work fine.

If you want to get all unique values without any approximation or setting a magic number (size: 500), then use COMPOSITE AGGREGATION (ES 6.5+).

From official documentation:

"If you want to retrieve all terms or all combinations of terms in a nested terms aggregation you should use the COMPOSITE AGGREGATION which allows to paginate over all possible terms rather than setting a size greater than the cardinality of the field in the terms aggregation. The terms aggregation is meant to return the top terms and does not allow pagination."

Implementation example in JavaScript:

const ITEMS_PER_PAGE = 1000;_x000D_
_x000D_
const body =  {_x000D_
    "size": 0, // Returning only aggregation results: https://www.elastic.co/guide/en/elasticsearch/reference/current/returning-only-agg-results.html_x000D_
    "aggs" : {_x000D_

You could also put non-breaking spaces (&nbsp;) in lieu of the spaces so that they're forced to stay together.

RxJS Operators are functions that build on the observables foundation to enable sophisticated manipulation of collections.

For example, RxJS defines operators such as map(), filter(), concat(), and flatMap().

You can use pipes to link operators together. Pipes let you combine multiple functions into a single function.

The pipe() function takes as its arguments the functions you want to combine, and returns a new function that, when executed, runs the composed functions in sequence.

Loading a python3 generated *.pyc file with python2 also causes this error.

•   is the character entity reference (meant to be easily parseable by humans).
•   is the numeric entity reference (meant to be easily parseable by machines).

They are the same except for the fact that the latter does not need another lookup table to find its actual value. The lookup table is called a DTD, by the way.

You can read more about character entity references in the offical W3C documents.

if(-e $base_path){print "Something";}

would do the trick

td.setAttribute('rowspan',x);

It's just a short form of writing an if-then-else statement. It means the same as the following code:

if(inPseudoEditMode)
  label.frame = kLabelIndentedRect;
else
  label.frame = kLabelRect;

Ah, the dreaded loose comparison operator strikes again. Never use it. Always use strict comparison, === or !== instead.

If you search Google for the version you want, you should be able to find a download link. For example, Android NDK r5b is available at http://androgeek.info/?p=296

On another note, it might be a good idea to look at why your code doesn't compile against the latest version and fix it.

See this. Your code would be something like the following:

from django.db.models import Max
# Generates a "SELECT MAX..." query
Argument.objects.aggregate(Max('rating')) # {'rating__max': 5}

You can also use this on existing querysets:

from django.db.models import Max
args = Argument.objects.filter(name='foo') # or whatever arbitrary queryset
args.aggregate(Max('rating')) # {'rating__max': 5}

If you need the model instance that contains this max value, then the code you posted is probably the best way to do it:

arg = args.order_by('-rating')[0]

Note that this will error if the queryset is empty, i.e. if no arguments match the query (because the [0] part will raise an IndexError). If you want to avoid that behavior and instead simply return None in that case, use .first():

arg = args.order_by('-rating').first() # may return None

setInterval sets up a recurring timer. It returns a handle that you can pass into clearInterval to stop it from firing:

var handle = setInterval(drawAll, 20);

// When you want to cancel it:
clearInterval(handle);
handle = 0; // I just do this so I know I've cleared the interval

On browsers, the handle is guaranteed to be a number that isn't equal to 0; therefore, 0 makes a handy flag value for "no timer set". (Other platforms may return other values; NodeJS's timer functions return an object, for instance.)

To schedule a function to only fire once, use setTimeout instead. It won't keep firing. (It also returns a handle you can use to cancel it via clearTimeout before it fires that one time if appropriate.)

setTimeout(drawAll, 20);

This error is caused by a line of code in /usr/share/phpmyadmin/libraries/sql.lib.php.

It seems when I installed phpMyAdmin using apt, the version in the repository (phpMyAdmin v4.6.6) is not fully compatible with PHP 7.2. There is a newer version available on the official website (v4.8 as of writing), which fixes these compatibility issues with PHP 7.2.

You can download the latest version and install it manually or wait for the repositories to update with the newer version.

Alternatively, you can make a small change to sql.lib.php to fix the error.

Firstly, backup sql.lib.php before editing.

1-interminal:

sudo cp /usr/share/phpmyadmin/libraries/sql.lib.php /usr/share/phpmyadmin/libraries/sql.lib.php.bak

2-Edit sql.lib.php. Using vi:

sudo vi /usr/share/phpmyadmin/libraries/sql.lib.php

OR Using nano:

sudo nano /usr/share/phpmyadmin/libraries/sql.lib.php

Press CTRL + W (for nano) or ? (for vi/vim) and search for (count($analyzed_sql_results['select_expr'] == 1)

Replace it with ((count($analyzed_sql_results['select_expr']) == 1)

Save file and exit. (Press CTRL + X, press Y and then press ENTER for nano users / (for vi/vim) hit ESC then type :wq and press ENTER)

Try This:

CGSize scrollSize = CGSizeMake([UIScreen mainScreen].bounds.size.width, scrollHeight);
[scrollView setContentSize: scrollSize];

because of two way binding, To prevent error of:

ExpressionChangedAfterItHasBeenCheckedError: Expression has changed after it was 
checked.

you can call a function to change model like this:

<input [ngModel]="item.value" 
  (ngModelChange)="getNewValue($event)" name="inputField" type="text" />


import { UseMyPipeToFormatThatValuePipe } from './path';

constructor({
    private UseMyPipeToFormatThatValue: UseMyPipeToFormatThatValuePipe,
})

getNewValue(ev: any): any {
    item.value= this.useMyPipeToFormatThatValue.transform(ev);
}

it'll be good if there is a better solution to prevent this error.

Turn on gzip if you want to do it properly. You can also just do something like this:

$this->output = preg_replace(
    array(
        '/ {2,}/',
        '/<!--.*?-->|\t|(?:\r?\n[ \t]*)+/s'
    ),
    array(
        ' ',
        ''
    ),
    $this->output
);

This removes about 30% of the page size by turning your html into one line, no tabs, no new lines, no comments. Mileage may vary

I think the other answers miss one important detail regarding the property name to use in the EL expression. The rules for converting from the method names to property names are specified in 'Introspector.decpitalize` which is part of the java bean standard:

This normally means converting the first character from upper case to lower case, but in the (unusual) special case when there is more than one character and both the first and second characters are upper case, we leave it alone.

Thus "FooBah" becomes "fooBah" and "X" becomes "x", but "URL" stays as "URL".

So in your case the JSTL code should look like the following, note the capital 'P':

<c:if test = "${ansokanInfo.PSystem == 'NAT'}">

A bit old, but I thought sharing how I'd do it, based on chubbsondubs' answer: I use FrameLayout (see Documentation), since it is used to contain a single view, and inflate into it the view from the xml.

Code following:

public class MyView extends FrameLayout {
    public MyView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        initView();
    }

    public MyView(Context context, AttributeSet attrs) {
        super(context, attrs);
        initView();
    }

    public MyView(Context context) {
        super(context);
        initView();
    }

    private void initView() {
        inflate(getContext(), R.layout.my_view_layout, this);
    }
}

The -jar option is mutually exclusive of -classpath. See an old description here

-jar

Execute a program encapsulated in a JAR file. The first argument is the name of a JAR file instead of a startup class name. In order for this option to work, the manifest of the JAR file must contain a line of the form Main-Class: classname. Here, classname identifies the class having the public static void main(String[] args) method that serves as your application's starting point.

See the Jar tool reference page and the Jar trail of the Java Tutorial for information about working with Jar files and Jar-file manifests.

When you use this option, the JAR file is the source of all user classes, and other user class path settings are ignored.

A quick and dirty hack is to append your classpath to the bootstrap classpath:

-Xbootclasspath/a:path

Specify a colon-separated path of directires, JAR archives, and ZIP archives to append to the default bootstrap class path.

However, as @Dan rightly says, the correct solution is to ensure your JARs Manifest contains the classpath for all JARs it will need.

If you have one condition check instance function in javascript. it's easy to use ternary operator. which will only need one single line to implement. Ex:

    private module : string ='';
    private page:boolean = false;
    async mounted(){
     if(this.module=== 'Main')
    {
    this.page = true;}
    else{
    this.page = false;
    }
}

a function like this with one condition can be written as follow.

this.page = this.module=== 'Main' ?true:false;

condition ? if True : if False

iOS Icons

• Set AppIcon in Images.xcassets.
• Add 9 different size icons:
  • 29pt
  • 29pt*2
  • 29pt*3
  • 40pt*2
  • 40pt*3
  • 57pt
  • 57pt*2
  • 60pt*2
  • 60pt*3.

Images.xcassets will look like this:

Android Icons

• Put ic_launcher.png in folders [ProjectDirectory]/android/app/src/main/res/mipmap-*/.
  • 72*72 ic_launcher.png in mipmap-hdpi.
  • 48*48 ic_launcher.png in mipmap-mdpi.
  • 96*96 ic_launcher.png in mipmap-xhdpi.
  • 144*144 ic_launcher.png in mipmap-xxhdpi.
  • 192*192 ic_launcher.png in mipmap-xxxhdpi.

Update 2019 Android

The latest versions of react native also supports round icon. For this particular case, you have two choices:

A. Add round icons: In each mipmap folder, add additionally to the ic_launcher.png file also a round version called ic_launcher_round.png with the same size.

B. Remove round icons: Inside yourProjectFolder/android/app/src/main/AndroidManifest.xml remove the line android:roundIcon="@mipmap/ic_launcher_round"and save it.

Otherwhise the build throws an error.

The ssh2 functions aren't very good. Hard to use and harder yet to install, using them will guarantee that your code has zero portability. My recommendation would be to use phpseclib, a pure PHP SFTP implementation.

No, you can specify the list as a keyword argument to your function.

alist = []
def fn(alist=alist):
    alist.append(1)
fn()
print alist    # [1]

I'd say it's bad practice though. Kind of too hackish. If you really need to use a globally available singleton-like data structure, I'd use the module level variable approach, i.e. put 'alist' in a module and then in your other modules import that variable:

In file foomodule.py:

alist = []

In file barmodule.py:

import foomodule
def fn():
    foomodule.alist.append(1)
print foomodule.alist    # [1]

you can also see this:

if (cursor.moveToFirst()) {
// record exists
} else {
// record not found
}

OR

You just check Cursor not null after that why you check count not 0.

So, that you try this...

DBHelper.getReadableDatabase();

Cursor mCursor = db.rawQuery("SELECT * FROM " + DATABASE_TABLE + " WHERE    yourKey=? AND yourKey1=?", new String[]{keyValue,keyvalue1});

if (mCursor != null)
{
            return true;
/* record exist */
 }
else
{
        return false;
/* record not exist */
}

Based on @ofer.sheffer answer this command will mass rename and append the current date to the filename. ie "file.txt" becomes "20180329 - file.txt" for all files in the current folder

for %a in (*.*) do ren "%a" "%date:~-4,4%%date:~-7,2%%date:~-10,2% - %a"

Alternate way: Dismount the drive (from settings/storage) and re-mount the sdcard also fixes the problem. (verify by moving a file from internal storage to sdcard) In any case, this simple method saved my butt this time :)

Try the following:

<link rel="icon" type="image/png" href="img/iconimg.png" />

NB: The href is the directory to your image example. Your image is in a folder called "img" and your image name is "iconimg" and if it is a png use .png, if it is a jpg then .jpg. Remember to do this in the head of your file and not in the body.

There's a static method in ToolStripRenderer class, named CreateDisabledImage. Its usage is as simple as:

Bitmap c = new Bitmap("filename");
Image d = ToolStripRenderer.CreateDisabledImage(c);

It uses a little bit different matrix than the one in the accepted answer and additionally multiplies it by a transparency of value 0.7, so the effect is slightly different than just grayscale, but if you want to just get your image grayed, it's the simplest and best solution.

The following approach seems simple and can be used with variables of different size:

import hickle as hkl
# write variables to filename [a,b,c can be of any size]
hkl.dump([a,b,c], filename)

# load variables from filename
a,b,c = hkl.load(filename)

1. Indexed fields (fields with numerical keys) are stored as a holy array inside the object. Therefore lookup time is O(1)

2. Same for a lookup array it's O(1)

3. Iterating through an array of objects and testing their ids against the provided one is a O(n) operation.

In my case, my problem was environmental. Meaning, I did something wrong in my bash session. After attempting nearly everything in this thread, I opened a new bash session and everything was back to normal.

A build, as Makefile understands it, consists of a lot of targets. For example, to build a project you might need

1. Build file1.o out of file1.c
2. Build file2.o out of file2.c
3. Build file3.o out of file3.c
4. Build executable1 out of file1.o and file3.o
5. Build executable2 out of file2.o

If you implemented this workflow with makefile, you could make each of the targets separately. For example, if you wrote

make file1.o

it would only build that file, if necessary.

The name of all is not fixed. It's just a conventional name; all target denotes that if you invoke it, make will build all what's needed to make a complete build. This is usually a dummy target, which doesn't create any files, but merely depends on the other files. For the example above, building all necessary is building executables, the other files being pulled in as dependencies. So in the makefile it looks like this:

all: executable1 executable2

all target is usually the first in the makefile, since if you just write make in command line, without specifying the target, it will build the first target. And you expect it to be all.

all is usually also a .PHONY target. Learn more here.

After spending lot of time on internet. I found that NONE of the option worked for I tried Right click on the server -> Clean. didn't work.

What worked is:

You just to add<absolute-ordering/> tag to your web.xml just under the <display-name> tag and it should work.for more detail click here

Gmail servers use SMTP Authentication under SSL or TLS. I think that there is no way to use the mail() function under that circumstances, so you might want to check these alternatives:

• PEAR::Mail
• phpMailer
• Nette\Mail

They all support SMTP auth under SSL.

You'll need to enable the php_openssl extension in your php.ini.

You cannot disable linker warning 4099, as said @John Weldon.

You should rebuild library with some project configuration changes. You have several options:

• Save PDB file with debug information is same folder where you save .lib file. Set value "$(OutDir)$(TargetName).pdb" to Properties->C/C++->Output Files-Program Database File Name
• Save debug information in .lib file. Set value "C7 compatible (/Z7)" to Properties->C/C++->General->Debug Information Format
• Disable generation debug information for this library. Remove value from Properties->C/C++->General->Debug Information Format
