This may be overkill for what you're looking for, but there is an npm package called marky that you can use to do this. It gives you a couple of extra features beyond just starting and stopping a timer. You just need to install it via npm and then import the dependency anywhere you'd like to use it. Here is a link to the npm package: https://www.npmjs.com/package/marky

An example of use after installing via npm would be as follows:

import * as _M from 'marky';

@Component({
 selector: 'app-test',
 templateUrl: './test.component.html',
 styleUrls: ['./test.component.scss']
})

export class TestComponent implements OnInit {
 Marky = _M;
}

constructor() {}

ngOnInit() {}

startTimer(key: string) {
 this.Marky.mark(key);
}

stopTimer(key: string) {
 this.Marky.stop(key);
}

key is simply a string which you are establishing to identify that particular measurement of time. You can have multiple measures which you can go back and reference your timer stats using the keys you create.

I found this multidrop-down menu which work great in all device.

Also, have hover style

It supports multi-level submenus with bootstrap 4.

Another way besides @Nahush's answer, if you are already using Express framework in the project then you can avoid using Nginx for reverse-proxy.

A simpler way is to use express-http-proxy

1. run npm run build to create the bundle.

   var proxy = require('express-http-proxy');
   
   var app = require('express')();
   
   //define the path of build
   
   var staticFilesPath = path.resolve(__dirname, '..', 'build');
   
   app.use(express.static(staticFilesPath));
   
   app.use('/api/api-server', proxy('www.api-server.com'));
   

Use "/api/api-server" from react code to call the API.

So, that browser will send request to the same host which will be internally redirecting the request to another server and the browser will feel that It is coming from the same origin ;)

In Bootstrap 4.3, col-xs-{value} is replaced by col-{value}

There is no change in sm, md, lg, xl remains the same.

.col-{value}
.col-sm-{value}
.col-md-{value}
.col-lg-{value}
.col-xl-{value}

If this is your app, if you connect the device to your computer, you can use the "Devices" option on Xcode's "Window" menu and then download the app's data container to your computer. Just select your app from the list of installed apps, and click on the "gear" icon and choose "Download Container".

Once you've downloaded it, right click on the file in the Finder and choose "Show Package Contents".

fwrite($handle, "<br>"."\r\n");

Add this under

$password = $_POST['password'].PHP_EOL;

this. .

Use option -t for sendmail.

in your case - echo -e $mail | /usr/sbin/sendmail -t and add yout Recepient list to message itself like To: [email protected] [email protected] right after the line From:.....

-t option means - Read message for recipients. To:, Cc:, and Bcc: lines will be scanned for recipient addresses. The Bcc: line will be deleted before transmission.

Try resetting your network settings

Settings -> General -> Reset -> Reset Network Settings

And try deleting the contents of your mac/pc lockdown folder. Here's the link, follow the steps on "Reset the Lockdown folder".

This one worked for me.

Unfortunately, all of your assumptions seem correct, and I don't think there's a way to do this. In order to save battery life, the iPhone's location services are based on movement. If the phone sits in one spot, it's invisible to location services.

The CLLocationManager will only call locationManager:didUpdateToLocation:fromLocation: when the phone receives a location update, which only happens if one of the three location services (cell tower, gps, wifi) perceives a change.

A few other things that might help inform further solutions:

• Starting & Stopping the services causes the didUpdateToLocation delegate method to be called, but the newLocation might have an old timestamp.

• Region Monitoring might help

• When running in the background, be aware that it may be difficult to get "full" LocationServices support approved by Apple. From what I've seen, they've specifically designed startMonitoringSignificantLocationChanges as a low power alternative for apps that need background location support, and strongly encourage developers to use this unless the app absolutely needs it.

Good Luck!

UPDATE: These thoughts may be out of date by now. Looks as though people are having success with @wjans answer, above.

I did not test the following snippet... hopefully it will point you towards the right direction:

    var jsreader = new JsonTextReader(new StringReader(stringData));
    var json = (JObject)new JsonSerializer().Deserialize(jsreader);
    var tableRows = from p in json["items"]
                 select new
                 {
                     Name = (string)p["Name"],
                     Age = (int)p["Age"],
                     Job = (string)p["Job"]
                 };

Had this same issue nothing worked, so I figured something weird with derived data.

In xcode 6.3.2 I had to:

In XCode Menu --> Preferences --> Locations Tab --> In Locations Change Derived Data to Relative and then toggle back to Default

Then the nib loaded fine.

These steps solved my problem:

1. Go into organizer
2. Devices
3. select your device
4. Delete the particular profile.
5. Run again

Tada...

It's worth the buck to apply for the Apple developer program. You will be able to use ad-hoc provisioning to distribute your app to testers and test devices. You're allowed to add 100 ad-hoc provisioning devices to your developer program.

Best Answer: Simply add http or https in your browser, the IP address, colon and port number. Example: https://123.23.145.67:80

i wanted to mention Jailbreak specifically (GitHub):

Jailbreak

Jailbreak is a tool for exporting certificates marked as non-exportable from the Windows certificate store. This can help when you need to extract certificates for backup or testing. You must have full access to the private key on the filesystem in order for jailbreak to work.

Prerequisites: Win32

You'll need to post your statement for more clarification. But...

That error means that the table you are inserting data into has a foreign key relationship with another table. Before data can be inserted, the value in the foreign key field must exist in the other table first.

yes, but why !!??

   Select CustomerID,
     Min(Case DBColumnName When 'FirstName' Then Data End) FirstName,
     Min(Case DBColumnName When 'MiddleName' Then Data End) MiddleName,
     Min(Case DBColumnName When 'LastName' Then Data End) LastName,
     Min(Case DBColumnName When 'Date' Then Data End) Date
   From table
   Group By CustomerId

Another good alternative: Marvin

You could also do this with a union query. As the number of columns increase, you would need to modify the query, but at least it would be a straight forward modification.

Select T.Id, T.Col1, T.Col2, T.Col3, A.TheMin
From   YourTable T
       Inner Join (
         Select A.Id, Min(A.Col1) As TheMin
         From   (
                Select Id, Col1
                From   YourTable

                Union All

                Select Id, Col2
                From   YourTable

                Union All

                Select Id, Col3
                From   YourTable
                ) As A
         Group By A.Id
       ) As A
       On T.Id = A.Id

You can use Lookback. It records your screen, face, voice and all gestures, and uploads them to your account on the web.

With the upcoming Xcode 7 it's now possible to install apps on your devices without an apple developer license, so now it is possible to skip the app store and you don't have to jailbreak your device.

Now everyone can get their app on their Apple device.

Xcode 7 and Swift now make it easier for everyone to build apps and run them directly on their Apple devices. Simply sign in with your Apple ID, and turn your idea into an app that you can touch on your iPad, iPhone, or Apple Watch. Download Xcode 7 beta and try it yourself today. Program membership is not required.

Quoted from: https://developer.apple.com/xcode/

Update:

XCode 7 is now released:

Free On-Device Development Now everyone can run and test their own app on a device—for free. You can run and debug your own creations on a Mac, iPhone, iPad, iPod touch, or Apple Watch without any fees, and no programs to join. All you need to do is enter your free Apple ID into Xcode. You can even use the same Apple ID you already use for the App Store or iTunes. Once you’ve perfected your app the Apple Developer Program can help you get it on the App Store.

See Launching Your App on Devices for detailed information about installing and running on devices.

• If you've got a string, and you expect it to always be an integer (say, if some web service is handing you an integer in string format), you'd use Int32.Parse().

• If you're collecting input from a user, you'd generally use Int32.TryParse(), since it allows you more fine-grained control over the situation when the user enters invalid input.

• Convert.ToInt32() takes an object as its argument. (See Chris S's answer for how it works)

  Convert.ToInt32() also does not throw ArgumentNullException when its argument is null the way Int32.Parse() does. That also means that Convert.ToInt32() is probably a wee bit slower than Int32.Parse(), though in practice, unless you're doing a very large number of iterations in a loop, you'll never notice it.

An alternative to Trikaldarshi's one line solution. (It avoids having to construct FileInfo objects)

long sizeInBytes = Directory.EnumerateFiles("{path}","*", SearchOption.AllDirectories).Sum(fileInfo => new FileInfo(fileInfo).Length);

In the numpy README.txt file, it says

After installation, tests can be run with:

python -c 'import numpy; numpy.test()'

This should be a sufficient test for proper installation.

Found a Fix:

1. First ensure that printing is working from Report Manager (open a report in Report Manager and print from there).

2. If it works go to Step 3, if you received the same error you need to install the following patches on the Report Server.

Way past the late season but I've just been looking at the answers given and have my tuppence worth:

Usage:

var one = strFormat('"{0}" is not {1}', 'aalert', 'defined');
var two = strFormat('{0} {0} {1} {2}', 3.14, 'a{2}bc', 'foo');

Method:

function strFormat() {
    var args = Array.prototype.slice.call(arguments, 1);
    return arguments[0].replace(/\{(\d+)\}/g, function (match, index) {
        return args[index];
    });
}

Result:

"aalert" is not defined
3.14 3.14 a{2}bc foo

Personally, I like to use named entities when they are available, because they make my HTML more readable. Because of that, I like to use ✓ for ✓ and ✗ for ✗. If you're not sure whether a named entity exists for the character you want, try the &what search site. It includes the name for each entity, if there is one.

As mentioned in the comments, ✓ and ✗ are not supported in HTML4, so you may be better off using the more cryptic ✓ and ✗ if you want to target the most browsers. The most definitive references I could find were on the W3C site: HTML4 and HTML5.

Calendar aGMTCalendar = Calendar.getInstance(TimeZone.getTimeZone("GMT")); Then all operations performed using the aGMTCalendar object will be done with the GMT time zone and will not have the daylight savings time or fixed offsets applied

Wrong!

Calendar aGMTCalendar = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
aGMTCalendar.getTime(); //or getTimeInMillis()

and

Calendar aNotGMTCalendar = Calendar.getInstance(TimeZone.getTimeZone("GMT-2"));aNotGMTCalendar.getTime();

will return the same time. Idem for

new Date(); //it's not GMT.

This will give you some control over the clicking, and looks tidy

<script>
var timeOut = 0;
function onClick(but)
{
    //code
    clearTimeout(timeOut);
    timeOut = setTimeout(function (){onClick(but)},1000);
}
</script>
<button onclick="onClick(this)">Start clicking</button>

From 5.2.2/2 (character display semantics) :

\b (backspace) Moves the active position to the previous position on the current line. If the active position is at the initial position of a line, the behavior of the display device is unspecified.

\n (new line) Moves the active position to the initial position of the next line.

\r (carriage return) Moves the active position to the initial position of the current line.

Here, your code produces :

• <new_line>ab
• \b : back one character
• write si : overrides the b with s (producing asi on the second line)
• \r : back at the beginning of the current line
• write ha : overrides the first two characters (producing hai on the second line)

In the end, the output is :

\nhai

I know this thread is old but, another solution was to run

$ mvn clean install -Dmaven.test.skip=true

And on IntelliJ do CMD + Shift + A (mac os) -> type "Reimport all Maven projects".

If that doesn't work, try forcing maven dependencies to be re-downloaded

$ mvn clean -U install -Dmaven.test.skip=true

The $push operator appends a specified value to an array.

{ $push: { <field1>: <value1>, ... } }

$push adds the array field with the value as its element.

Above answer fulfils all the requirements, but I got it working by doing the following

var objFriends = { fname:"fname",lname:"lname",surname:"surname" };
Friend.findOneAndUpdate(
   { _id: req.body.id }, 
   { $push: { friends: objFriends  } },
  function (error, success) {
        if (error) {
            console.log(error);
        } else {
            console.log(success);
        }
    });
)

If you are using lodash or npm, use lodash's merge function to deep copy all of the object's properties to a new empty object like so:

var objectCopy = lodash.merge({}, originalObject);

In a CSV file, each field is separated by a comma. The problem is, a field itself might have an embedded comma:

Name,Phone
"Woo, John",425-555-1212

You really need a library package that offer robust CSV support instead of relying on using comma as a field separator. I know that scripting languages such as Python has such support. However, I am comfortable with the Tcl scripting language so that is what I use. Here is a simple Tcl script which does what you are asking for:

#!/usr/bin/env tclsh

package require csv 
package require Tclx

# Parse the command line parameters
lassign $argv fileName columnNumber expectedValue

# Subtract 1 from columnNumber because Tcl's list index starts with a
# zero instead of a one
incr columnNumber -1

for_file line $fileName {
    set columns [csv::split $line]
    set columnValue [lindex $columns $columnNumber]
    if {$columnValue == $expectedValue} {
        puts $line
    }   
}

Save this script to a file called csv.tcl and invoke it as:

$ tclsh csv.tcl filename indexNumber expectedValue

Explanation

The script reads the CSV file line by line and store the line in the variable $line, then it split each line into a list of columns (variable $columns). Next, it picks out the specified column and assigned it to the $columnValue variable. If there is a match, print out the original line.

All you need to do is add "&" in front of your __get function to pass it as reference:

public function &__get ( $index )

Struggled with this one for a while.

If you mean using a literal, you simply have to create a binary string:

insert into Files (FileId, FileData) values (1, 0x010203040506)

And you will have a record with a six byte value for the FileData field.

You indicate in the comments that you want to just specify the file name, which you can't do with SQL Server 2000 (or any other version that I am aware of).

You would need a CLR stored procedure to do this in SQL Server 2005/2008 or an extended stored procedure (but I'd avoid that at all costs unless you have to) which takes the filename and then inserts the data (or returns the byte string, but that can possibly be quite long).

In regards to the question of only being able to get data from a SP/query, I would say the answer is yes, because if you give SQL Server the ability to read files from the file system, what do you do when you aren't connected through Windows Authentication, what user is used to determine the rights? If you are running the service as an admin (God forbid) then you can have an elevation of rights which shouldn't be allowed.

In PowerShell v5.1 this is slightly different compared to v5. According to MS documentation, it has to have a -Path parameter to specify the archive file path.

Expand-Archive -Path Draft.Zip -DestinationPath C:\Reference

Or else, this can be an actual path:

Expand-Archive -Path c:\Download\Draft.Zip -DestinationPath C:\Reference

While the accepted answer will work fine if the bytes you have from your subprocess are encoded using sys.stdout.encoding (or a compatible encoding, like reading from a tool that outputs ASCII and your stdout uses UTF-8), the correct way to write arbitrary bytes to stdout is:

sys.stdout.buffer.write(some_bytes_object)

This will just output the bytes as-is, without trying to treat them as text-in-some-encoding.

If you really want a general promiseWhen() function for this and other purposes, then by all means do so, using Bergi's simplifications. However, because of the way promises work, passing callbacks in this way is generally unnecessary and forces you to jump through complex little hoops.

As far as I can tell you're trying :

• to asynchronously fetch a series of user details for a collection of email addresses (at least, that's the only scenario that makes sense).
• to do so by building a .then() chain via recursion.
• to maintain the original order when handling the returned results.

Defined thus, the problem is actually the one discussed under "The Collection Kerfuffle" in Promise Anti-patterns, which offers two simple solutions :

• parallel asynchronous calls using Array.prototype.map()
• serial asynchronous calls using Array.prototype.reduce().

The parallel approach will (straightforwardly) give the issue that you are trying to avoid - that the order of the responses is uncertain. The serial approach will build the required .then() chain - flat - no recursion.

function fetchUserDetails(arr) {
    return arr.reduce(function(promise, email) {
        return promise.then(function() {
            return db.getUser(email).done(function(res) {
                logger.log(res);
            });
        });
    }, Promise.resolve());
}

Call as follows :

//Compose here, by whatever means, an array of email addresses.
var arrayOfEmailAddys = [...];

fetchUserDetails(arrayOfEmailAddys).then(function() {
    console.log('all done');
});

As you can see, there's no need for the ugly outer var count or it's associated condition function. The limit (of 10 in the question) is determined entirely by the length of the array arrayOfEmailAddys.

For some reason I was not able to use my scalar function until I referenced it using brackets, like so:

select [dbo].[fun_functional_score]('01091400003')

(Jun-Dec 2016) Most answers here are now out-of-date as: 1) GData APIs are the previous generation of Google APIs, and that's why it was hard for @Josh Brown to find that old GData Docs API documentation. While not all GData APIs have been deprecated, all newer Google APIs do not use the Google Data protocol; and 2) Google released a new Google Sheets API (not GData). In order to use the new API, you need to get the Google APIs Client Library for Python (it's as easy as pip install -U google-api-python-client [or pip3 for Python 3]) and use the latest Sheets API v4+, which is much more powerful & flexible than older API releases.

Here's one code sample from the official docs to help get you kickstarted. However, here are slightly longer, more "real-world" examples of using the API you can learn from (videos plus blog posts):

• Migrating SQL data to a Sheet plus code deep dive post
• Formatting text using the Sheets API plus code deep dive post
• Generating slides from spreadsheet data plus code deep dive post
• Those and others in the Sheets API video library

The latest Sheets API provides features not available in older releases, namely giving developers programmatic access to a Sheet as if you were using the user interface (create frozen rows, perform cell formatting, resizing rows/columns, adding pivot tables, creating charts, etc.), but NOT as if it was some database that you could perform searches on and get selected rows from. You'd basically have to build a querying layer on top of the API that does this. One alternative is to use the Google Charts Visualization API query language, which does support SQL-like querying. You can also query from within the Sheet itself. Be aware that this functionality existed before the v4 API, and that the security model was updated in Aug 2016. To learn more, check my G+ reshare to a full write-up from a Google Developer Expert.

Also note that the Sheets API is primarily for programmatically accessing spreadsheet operations & functionality as described above, but to perform file-level access such as imports/exports, copy, move, rename, etc., use the Google Drive API instead. Examples of using the Drive API:

• Listing your files in Google Drive and code deep dive post
• Google Drive: Uploading & Downloading Files plus "Poor man's plain text to PDF converter" code deep dive post (*)
• Exporting a Google Sheet as CSV blog post only

(*) - TL;DR: upload plain text file to Drive, import/convert to Google Docs format, then export that Doc as PDF. Post above uses Drive API v2; this follow-up post describes migrating it to Drive API v3, and here's a developer video combining both "poor man's converter" posts.

To learn more about how to use Google APIs with Python in general, check out my blog as well as a variety of Google developer videos (series 1 and series 2) I'm producing.

ps. As far as Google Docs goes, there isn't a REST API available at this time, so the only way to programmatically access a Doc is by using Google Apps Script (which like Node.js is JavaScript outside of the browser, but instead of running on a Node server, these apps run in Google's cloud; also check out my intro video.) With Apps Script, you can build a Docs app or an add-on for Docs (and other things like Sheets & Forms).

UPDATE Jul 2018: The above "ps." is no longer true. The G Suite developer team pre-announced a new Google Docs REST API at Google Cloud NEXT '18. Developers interested in getting into the early access program for the new API should register at https://developers.google.com/docs.

UPDATE Feb 2019: The Docs API launched to preview last July is now available generally to all... read the launch post for more details.

UPDATE Nov 2019: In an effort to bring G Suite and GCP APIs more inline with each other, earlier this year, all G Suite code samples were partially integrated with GCP's newer (lower-level not product) Python client libraries. The way auth is done is similar but (currently) requires a tiny bit more code to manage token storage, meaning rather than our libraries manage storage.json, you'll store them using pickle (token.pickle or whatever name you prefer) instead, or choose your own form of persistent storage. For you readers here, take a look at the updated Python quickstart example.

Improvisation to the function "humanTiming" by arnorhs. It would calculate a "fully stretched" translation of time string to human readable text version. For example to say it like "1 week 2 days 1 hour 28 minutes 14 seconds"

function humantime ($oldtime, $newtime = null, $returnarray = false)    {
    if(!$newtime) $newtime = time();
    $time = $newtime - $oldtime; // to get the time since that moment
    $tokens = array (
            31536000 => 'year',
            2592000 => 'month',
            604800 => 'week',
            86400 => 'day',
            3600 => 'hour',
            60 => 'minute',
            1 => 'second'
    );
    $htarray = array();
    foreach ($tokens as $unit => $text) {
            if ($time < $unit) continue;
            $numberOfUnits = floor($time / $unit);
            $htarray[$text] = $numberOfUnits.' '.$text.(($numberOfUnits>1)?'s':'');
            $time = $time - ( $unit * $numberOfUnits );
    }
    if($returnarray) return $htarray;
    return implode(' ', $htarray);
}

To kill a process by a specific keyword you could create an alias in ~/.bashrc (linux) or ~/.bash_profile (mac).

alias killps="kill -9 `ps -ef | grep '[k]eyword' | awk '{print $2}'`"

jQuery has some issues loading binary data using AJAX requests, as it does not yet implement some HTML5 XHR v2 capabilities, see this enhancement request and this discussion

Given that, you have one of two solutions:

First solution, abandon JQuery and use XMLHTTPRequest

Go with the native HTMLHTTPRequest, here is the code to do what you need

  var req = new XMLHttpRequest();
  req.open("GET", "/file.pdf", true);
  req.responseType = "blob";

  req.onload = function (event) {
    var blob = req.response;
    console.log(blob.size);
    var link=document.createElement('a');
    link.href=window.URL.createObjectURL(blob);
    link.download="Dossier_" + new Date() + ".pdf";
    link.click();
  };

  req.send();

Second solution, use the jquery-ajax-native plugin

The plugin can be found here and can be used to the XHR V2 capabilities missing in JQuery, here is a sample code how to use it

$.ajax({
  dataType: 'native',
  url: "/file.pdf",
  xhrFields: {
    responseType: 'blob'
  },
  success: function(blob){
    console.log(blob.size);
      var link=document.createElement('a');
      link.href=window.URL.createObjectURL(blob);
      link.download="Dossier_" + new Date() + ".pdf";
      link.click();
  }
});

You can use [[UINavigationBar appearance] setTintColor:myColor];

Since iOS 7 you need to set [[UINavigationBar appearance] setBarTintColor:myColor]; and also [[UINavigationBar appearance] setTranslucent:NO].

[[UINavigationBar appearance] setBarTintColor:myColor];
[[UINavigationBar appearance] setTranslucent:NO];

Another option is setting the log levels for specific tags:

adb logcat SensorService:S PowerManagerService:S NfcService:S power:I Sensors:E

If you just want to set the log levels for some tags you can do it on a tag by tag basis.

Pattern p = Pattern.compile("[^a-z0-9 ]", Pattern.CASE_INSENSITIVE);
Matcher m = p.matcher("I am a string");
boolean b = m.find();

if (b)
   System.out.println("There is a special character in my string");

The official MS line is "because it's not a functional operation" (ie it's a stateful operation).

Couldn't you do something like:

list.Select( x => x+1 )

or if you really need it in a List:

var someValues = new List<int>( list.Select( x => x+1 ) );

You can also use read like this

echo "enter your name"
read name
echo $name

You could have simply used Range("x1").value(11) something like below:

Sheets("Output").Range("$A$1:$A$500").value(11) =  Sheets(sheet_).Range("$A$1:$A$500").value(11)

range has default property "Value" plus value can have 3 optional orguments 10,11,12. 11 is what you need to tansfer both value and formats. It doesn't use clipboard so it is faster.- Durgesh

What you are trying to do is an extension of string slicing in Python:

Say all strings are of length 10, last char to be removed:

>>> st[:9]
'abcdefghi'

To remove last N characters:

>>> N = 3
>>> st[:-N]
'abcdefg'

In this link, we will find the solution Link.

setcookie("TestCookie", "", time() - 3600, "/~rasmus/", "b.com", 1);

public class Network {

Context context;

public Network(Context context){
    this.context = context;
}

public boolean isOnline() {
    ConnectivityManager cm =
            (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);

    NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
    return activeNetwork != null &&
                          activeNetwork.isConnectedOrConnecting();
}

}

Find the below code in xampp/phpmyadmin/config.inc.php

$cfg['Servers'][$i]['controluser']  = 'user_name/root';   
$cfg['Servers'][$i]['controlpass']  = 'passwaord';
$cfg['Servers'][$i]['auth_type']    = 'config';
$cfg['Servers'][$i]['user']         = 'user_name/root';
$cfg['Servers'][$i]['password']     = 'password';

Replace each statement above with the corresponding entry below:

$cfg['Servers'][$i]['controluser']  = 'root';   
$cfg['Servers'][$i]['controlpass']  = 'xxxx';
$cfg['Servers'][$i]['auth_type']    = 'config';
$cfg['Servers'][$i]['user']         = 'root';
$cfg['Servers'][$i]['password']     = 'xxxx';

Doing this caused localhost/phpmyadmin in the browser and the MySQL command prompt to work properly.

• CN = Common Name
• OU = Organizational Unit
• DC = Domain Component

These are all parts of the X.500 Directory Specification, which defines nodes in a LDAP directory.

You can also read up on LDAP data Interchange Format (LDIF), which is an alternate format.

You read it from right to left, the right-most component is the root of the tree, and the left most component is the node (or leaf) you want to reach.

Each = pair is a search criteria.

With your example query

("CN=Dev-India,OU=Distribution Groups,DC=gp,DC=gl,DC=google,DC=com");

In effect the query is:

From the com Domain Component, find the google Domain Component, and then inside it the gl Domain Component and then inside it the gp Domain Component.

In the gp Domain Component, find the Organizational Unit called Distribution Groups and then find the the object that has a common name of Dev-India.

Only to supplement. If you need to pass a variable and iterate it, you can do just like so:

function start(counter){
  if(counter < 10){
    setTimeout(function(){
      counter++;
      console.log(counter);
      start(counter);
    }, 1000);
  }
}
start(0);

Output:

1
2
3
...
9
10

One line per second.

This code worked for me. Easy fix but probably not a preferred way.

public void onClick (View v) {
    createdDialog(0).show(); // Instead of showDialog(0);
}

protected Dialog createdDialog(int id) {
    // Your code
}

The syntax of the class creation statement:

class <ClassName>(superclass):
    #code follows

In the absence of any other superclasses that you specifically want to inherit from, the superclass should always be object, which is the root of all classes in Python.

object is technically the root of "new-style" classes in Python. But the new-style classes today are as good as being the only style of classes.

But, if you don't explicitly use the word object when creating classes, then as others mentioned, Python 3.x implicitly inherits from the object superclass. But I guess explicit is always better than implicit (hell)

Reference

Since you didn't refer to self in the bar method body, PyCharm is asking if you might have wanted to make bar static. In other programming languages, like Java, there are obvious reasons for declaring a static method. In Python, the only real benefit to a static method (AFIK) is being able to call it without an instance of the class. However, if that's your only reason, you're probably better off going with a top-level function - as note here.

In short, I'm not one hundred percent sure why it's there. I'm guessing they'll probably remove it in an upcoming release.

Python adds the folder containing the script you launch to the PYTHONPATH, so if you run

python application/app2/some_folder/some_file.py

Only the folder application/app2/some_folder is added to the path (not the base dir that you're executing the command in). Instead, run your file as a module and add a __init__.py in your some_folder directory.

python -m application.app2.some_folder.some_file

This will add the base dir to the python path, and then classes will be accessible via a non-relative import.

1. According to composer's manual:

   require-dev (root-only)

   Lists packages required for developing this package, or running tests, etc. The dev requirements of the root package are installed by default. Both install or update support the --no-dev option that prevents dev dependencies from being installed.

   So running composer install will also download the development dependencies.

2. The reason is actually quite simple. When contributing to a specific library you may want to run test suites or other develop tools (e.g. symfony). But if you install this library to a project, those development dependencies may not be required: not every project requires a test runner.

Hope it's working for you

Also, a blank XML file will return the same Root elements is missing exception. Each XML file must have a root element / node which encloses all the other elements.

SOAP is useful from a tooling perspective because the WSDL is so easily consumed by tools. So, you can get Web Service clients generated for you in your favorite language.

REST plays well with AJAX'y web pages. If you keep your requests simple, you can make service calls directly from your JavaScript, and that comes in very handy. Try to stay away from having any namespaces in your response XML, I've seen browsers choke on those. So, xsi:type is probably not going to work for you, no overly complex XML Schemas.

REST tends to have better performance as well. CPU requirements of the code generating REST responses tend to be lower than what SOAP frameworks exhibit. And, if you have your XML generation ducks lined up on the server side, you can effectively stream XML out to the client. So, imagine you're reading rows of database cursor. As you read a row, you format it as an XML element, and you write that directly out to the service consumer. This way, you don't have to collect all of the database rows in memory before starting to write your XML output - you read and write at the same time. Look into novel templating engines or XSLT to get the streaming to work for REST.

SOAP on the other hand tends to get generated by tool-generated services as a big blob and only then written. This is not an absolute truth, mind you, there are ways to get streaming characteristics out of SOAP, like by using attachments.

My decision making process is as follows: if I want my service to be easily tooled by consumers, and the messages I write will be medium-to-small-ish (10MB or less), and I don't mind burning some extra CPU cycles on the server, I go with SOAP. If I need to serve to AJAX on web browsers, or I need the thing to stream, or my responses are gigantic, I go REST.

Finally, there are lots of great standards built up around SOAP, like WS-Security and getting stateful Web Services, that you can plug in to if you're using the right tools. That kind of stuff really makes a difference, and can help you satisfy some hairy requirements.

SELECT * FROM service s WHERE s.service_id = ?;

   print 'no data'

I would recomnend using box-sizing.

  -webkit-box-sizing:border-box;
  -moz-box-sizing:border-box;
  -ms-box-sizing:border-box;
  box-sizing:border-box;

#bar{
  border: 10px solid green;
  }

db.messages.find( { headers : { From: "[email protected]" } } )

This queries for documents where headers equals { From: ... }, i.e. contains no other fields.

db.messages.find( { 'headers.From': "[email protected]" } )

This only looks at the headers.From field, not affected by other fields contained in, or missing from, headers.

Dot-notation docs

Contrary to what most are posting, this is NOT an IDE thing. It is a language thing. The #region is a C# statement.

You should grab the standard input of the su process just launched and write down the command there, otherwise you are running the commands with the current UID.

Try something like this:

try{
    Process su = Runtime.getRuntime().exec("su");
    DataOutputStream outputStream = new DataOutputStream(su.getOutputStream());

    outputStream.writeBytes("screenrecord --time-limit 10 /sdcard/MyVideo.mp4\n");
    outputStream.flush();

    outputStream.writeBytes("exit\n");
    outputStream.flush();
    su.waitFor();
}catch(IOException e){
    throw new Exception(e);
}catch(InterruptedException e){
    throw new Exception(e);
}

You could use CSS to do that, but it wouldn't be supported in IE8-. You can use some site like http://borderradius.com to come up with actual CSS you'd use, which would look something like this (again, depending on how many browsers you're trying to support):

-webkit-border-radius: 5px;
-moz-border-radius: 5px;
border-radius: 5px;

I'm not sure if it's worth it, but you can emulate Java's named loops with a few simple macros:

#define LOOP_NAME(name) \
    if ([[maybe_unused]] constexpr bool _namedloop_InvalidBreakOrContinue = false) \
    { \
        [[maybe_unused]] CAT(_namedloop_break_,name): break; \
        [[maybe_unused]] CAT(_namedloop_continue_,name): continue; \
    } \
    else

#define BREAK(name) goto CAT(_namedloop_break_,name)
#define CONTINUE(name) goto CAT(_namedloop_continue_,name)

#define CAT(x,y) CAT_(x,y)
#define CAT_(x,y) x##y

Example usage:

#include <iostream>

int main()
{
    // Prints:
    // 0 0
    // 0 1
    // 0 2
    // 1 0
    // 1 1

    for (int i = 0; i < 3; i++) LOOP_NAME(foo)
    {
        for (int j = 0; j < 3; j++)
        {
            std::cout << i << ' ' << j << '\n';
            if (i == 1 && j == 1)
                BREAK(foo);
        }
    }
}

Another example:

#include <iostream>

int main()
{
    // Prints: 
    // 0
    // 1
    // 0
    // 1
    // 0
    // 1

    int count = 3;
    do LOOP_NAME(foo)
    {
        for (int j = 0; j < 3; j++)
        {
            std::cout << ' ' << j << '\n';
            if (j == 1)
                CONTINUE(foo);
        }
    }
    while(count-- > 1);
}

You might have 10,000 users total, but that's not the same as concurrent users. In this context, concurrent scripts being run.

For example, if your visitor visits index.php, and it makes a database query to get some user details, that request might live for 250ms. You can limit how long those MySQL connections live even further by opening and closing them only when you are querying, instead of leaving it open for the duration of the script.

While it is hard to make any type of formula to predict how many connections would be open at a time, I'd venture the following:

You probably won't have more than 500 active users at any given time with a user base of 10,000 users. Of those 500 concurrent users, there will probably at most be 10-20 concurrent requests being made at a time.

That means, you are really only establishing about 10-20 concurrent requests.

As others mentioned, you have nothing to worry about in that department.

The API does not support that directly. You can use the for(int i..) loop and count the elements or use subLists(0, size - 1) and handle the last element explicitly:

  if(x.isEmpty()) return;
  int last = x.size() - 1;
  for(Integer i : x.subList(0, last)) out.println(i);
  out.println("last " + x.get(last));

This is only useful if it does not introduce redundancy. It performs better than the counting version (after the subList overhead is amortized). (Just in case you cared after the boxing anyway).

The documentation on this is pretty clear. It's a UIView subclass so you use it like any other view. To start/stop the animation you use

[activityIndicator startAnimating];
[activityIndicator stopAnimating];

We can hide the content inside a by using the following inline css:

<div style="visibility:hidden"></div>

for example:

<td><div style="visibility:hidden">Your Content Goes Here:</div></td>

They represent [ and ]. The encoding is called "URL encoding".

I wonder, why you can't use that Google's Collection API with JDK 1.6. Does it say so? I think you can, there should not be any compatibility issues, as it is built for a lower version. The case would have been different if that were built for 1.6 and you are running 1.5.

Am I wrong somewhere?

Add

android:screenOrientation="portrait" 

or

 android:screenOrientation="landscape" 

to the <activity> element/s in the manifest and you're done.

The startup project that references the project where Entity Framework is being used needs the following two assemblies in it's bin folder:

• EntityFramework.dll
• EntityFramework.SqlServer.dll

Adding a <section> to the <configSections> of the .config file on the startup project makes the first assembly available in that bin directory. You can copy this from the .config file of your Entity Framework project:

<configSections>
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
</configSections>

To make the second .dll available in the bin folder, although not practical, a manual copy from the bin folder of the Entity Framework project can be made. A better alternative is to add to the Post-Build Events of the Entity Framework project the following lines, which will automate the process:

cd $(ProjectDir)
xcopy /y bin\Debug\EntityFramework.SqlServer.dll ..\{PATH_TO_THE_PROJECT_THAT_NEEDS_THE_DLL}\bin\Debug\

Use SpecialCells to delete only the rows that are visible after autofiltering:

ActiveSheet.Range("$A$1:$I$" & lines).SpecialCells _
    (xlCellTypeVisible).EntireRow.Delete

If you have a header row in your range that you don't want to delete, add an offset to the range to exclude it:

ActiveSheet.Range("$A$1:$I$" & lines).Offset(1, 0).SpecialCells _
    (xlCellTypeVisible).EntireRow.Delete

TL;DR

Details

Advantages and disadvantages are subjective. They can result in a dichotomy (an advantage for some, but considered disadvantage for others). Instead, I laid out above the factors that can help you decide which one to pick.

Existence during the first HTTP request-and-response

Let's just say you are a server-side person who wants to process both the session and cookie. The first HTTP handshake will go like so:

1. Browser prepares the HTTP request -- SESSIONS: not available; COOKIES: not available
2. Browser sends the HTTP request
3. Server receives the HTTP request
4. Server processes the HTTP request -- SESSIONS: existed; COOKIES: cast
5. Server sends the HTTP response
6. Browser receives the HTTP response
7. Browser processes the HTTP response -- SESSIONS: not available; COOKIES: existed

In step 1, the browser have no idea of the contents of both sessions and cookies. In step 4, the server can have the opportunity to set the values of the session and cookies.

Availability during the succeeding HTTP requests-and-responses

1. Browser prepares the HTTP request -- SESSIONS: not available; COOKIES: available
2. Browser sends the HTTP request
3. Server receives the HTTP request
4. Server processes the HTTP request -- SESSIONS: available; COOKIES: available
5. Server sends the HTTP response
6. Browser receives the HTTP response
7. Browser processes the HTTP response -- SESSIONS: not available; COOKIES: available

Payload

Let's say in a single web page you are loading 20 resources hosted by example.com, those 20 resources will carry extra bytes of information about the cookies. Even if it's just a resource request for CSS or a JPG image, it would still carry cookies in their headers on the way to the server. Should an HTTP request to a JPG resource carry a bunch of unnecessary cookies?

Deprecation

There is no replacement for sessions. For cookies, there are many other options in storing data in the browser rather than the old school cookies.

Storing of user data

Session is safer for storing user data because it can not be modified by the end-user and can only be set on the server-side. Cookies on the other hand can be hijacked because they are just stored on the browser.

iframes are used a lot to include complete pages. When those pages are hosted on another domain you get problems with cross side scripting and stuff. There are ways to fix this.

Frames were used to divide your page into multiple parts (for example, a navigation menu on the left). Using them is no longer recommended.

The Status Value being returned by a Stored Procedure can only be an INT datatype. You cannot return other datatypes in the RETURN statement.

From Lesson 2: Designing Stored Procedures:

Every stored procedure can return an integer value known as the execution status value or return code.

If you still want a table returned from the SP, you'll either have to work the record set returned from a SELECT within the SP or tie into an OUTPUT variable that passes an XML datatype.

As a one liner using list comprehension and numpy:

[ax.annotate(x[0], (x[1], x[2])) for x in np.array([n,z,y]).T]

setup is ditto to Rutger's answer.

I'm using a workaround by returning a function with an object of my global variables:

function globalVariables(){
  var variables = {
    sheetName: 'Sheet1',
    variable1: 1,
    variable2: 2
  };
  return variables;
}

function functionThatUsesVariable (){
  var sheet =   SpreadsheetApp.getActiveSpreadsheet().getSheetByName(globalVariables().sheetName);
}

In laravel 5.1,

 <link rel="stylesheet" href="{{URL::asset('assets/css/bootstrap.min.css')}}">
 <script type="text/javascript" src="{{URL::asset('assets/js/jquery.min.js')}}"></script>

The profiler trace puts it into perspective.

• Query A: 1.3 secs CPU, 1.4 secs duration
• Query B: 2.3 secs CPU, 1.2 secs duration

Query B is using parallelism: CPU > duration eg the query uses 2 CPUs, average 1.15 secs each

Query A is probably not: CPU < duration

This explains cost relative to batch: 17% of the for the simpler, non-parallel query plan.

The optimiser works out that query B is more expensive and will benefit from parallelism, even though it takes extra effort to do so.

Remember though, that query B uses 100% of 2 CPUS (so 50% for 4 CPUs) for one second or so. Query A uses 100% of a single CPU for 1.5 seconds.

The peak for query A is lower, at the expense of increased duration. With one user, who cares? With 100, perhaps it makes a difference...

I was facing the same problem and found a solution to get the code to work.

The code given in the android-Sdk/samples/android-?/ApiDemos works fine. Copy paste each folder in the android project and then in the MediaPlayerDemo_Video.java put the path of the video you want to stream in the path variable. It is left blank in the code.

The following video stream worked for me: http://www.pocketjourney.com/downloads/pj/video/famous.3gp

I know that RTSP protocol is to be used for streaming, but mediaplayer class supports http for streaming as mentioned in the code.

I googled for the format of the video and found that the video if converted to mp4 or 3gp using Quicktime Pro works fine for streaming.

I tested the final apk on android 2.1. The application dosent work on emulators well. Try it on devices.

I hope this helps..

Turning off the instant run(File >>Settings >>Build,Execution,Deployment >> Instant Run), solved my issue

$newtimestamp = strtotime('2011-11-17 05:05 + 16 minute');
echo date('Y-m-d H:i:s', $newtimestamp);

result is

2011-11-17 05:21:00

Live demo is here

If you are no familiar with strtotime yet, you better head to php.net to discover it's great power :-)

Like this:

function createJSON() {
    jsonObj = [];
    $("input[class=email]").each(function() {

        var id = $(this).attr("title");
        var email = $(this).val();

        item = {}
        item ["title"] = id;
        item ["email"] = email;

        jsonObj.push(item);
    });

    console.log(jsonObj);
}

Explanation

You are looking for an array of objects. So, you create a blank array. Create an object for each input by using 'title' and 'email' as keys. Then you add each of the objects to the array.

If you need a string, then do

jsonString = JSON.stringify(jsonObj);

Sample Output

[{"title":"QA","email":"a@b"},{"title":"PROD","email":"b@c"},{"title":"DEV","email":"c@d"}] 

Best practice ever

Create Interface named with PreferenceManager:

// Interface to save values in shared preferences and also for retrieve values from shared preferences
public interface PreferenceManager {

    SharedPreferences getPreferences();
    Editor editPreferences();

    void setString(String key, String value);
    String getString(String key);

    void setBoolean(String key, boolean value);
    boolean getBoolean(String key);

    void setInteger(String key, int value);
    int getInteger(String key);

    void setFloat(String key, float value);
    float getFloat(String key);

}

How to use with Activity / Fragment:

public class HomeActivity extends AppCompatActivity implements PreferenceManager{

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout_activity_home);
    }

    @Override
    public SharedPreferences getPreferences(){
        return getSharedPreferences("SP_TITLE", Context.MODE_PRIVATE);
    }

    @Override
    public SharedPreferences.Editor editPreferences(){
        return getPreferences().edit();
    }

    @Override
    public void setString(String key, String value) {
        editPreferences().putString(key, value).commit();
    }

    @Override
    public String getString(String key) {
        return getPreferences().getString(key, "");
    }

    @Override
    public void setBoolean(String key, boolean value) {
        editPreferences().putBoolean(key, value).commit();
    }

    @Override
    public boolean getBoolean(String key) {
        return  getPreferences().getBoolean(key, false);
    }

    @Override
    public void setInteger(String key, int value) {
        editPreferences().putInt(key, value).commit();
    }

    @Override
    public int getInteger(String key) {
        return getPreferences().getInt(key, 0);
    }

    @Override
    public void setFloat(String key, float value) {
        editPreferences().putFloat(key, value).commit();
    }

    @Override
    public float getFloat(String key) {
        return getPreferences().getFloat(key, 0);
    }
}

Note: Replace your key of SharedPreference with SP_TITLE.

Examples:

Store string in shareperence:

setString("my_key", "my_value");

Get string from shareperence:

String strValue = getString("my_key");

Hope this will help you.

for(int i = 0; i < array.length; i++)
{
    System.out.println(array[i]);
}

or

for(String value : array)
{
    System.out.println(value);
}

The second version is a "for-each" loop and it works with arrays and Collections. Most loops can be done with the for-each loop because you probably don't care about the actual index. If you do care about the actual index us the first version.

Just for completeness you can do the while loop this way:

int index = 0;

while(index < myArray.length)
{
  final String value;

  value = myArray[index];
  System.out.println(value);
  index++;
}

But you should use a for loop instead of a while loop when you know the size (and even with a variable length array you know the size... it is just different each time).

Just use the Date property:

var today = DateTime.Today;

var q = db.Games.Where(t => t.StartDate.Date >= today)
                .OrderBy(t => t.StartDate);

Note that I've explicitly evaluated DateTime.Today once so that the query is consistent - otherwise each time the query is executed, and even within the execution, Today could change, so you'd get inconsistent results. For example, suppose you had data of:

Entry 1: March 8th, 8am
Entry 2: March 10th, 10pm
Entry 3: March 8th, 5am
Entry 4: March 9th, 8pm

Surely either both entries 1 and 3 should be in the results, or neither of them should... but if you evaluate DateTime.Today and it changes to March 9th after it's performed the first two checks, you could end up with entries 1, 2, 4.

Of course, using DateTime.Today assumes you're interested in the date in the local time zone. That may not be appropriate, and you should make absolutely sure you know what you mean. You may want to use DateTime.UtcNow.Date instead, for example. Unfortunately, DateTime is a slippery beast...

EDIT: You may also want to get rid of the calls to DateTime static properties altogether - they make the code hard to unit test. In Noda Time we have an interface specifically for this purpose (IClock) which we'd expect to be injected appropriately. There's a "system time" implementation for production and a "stub" implementation for testing, or you can implement it yourself.

You can use the same idea without using Noda Time, of course. To unit test this particular piece of code you may want to pass the date in, but you'll be getting it from somewhere - and injecting a clock means you can test all the code.

instanceof cannot be used with primitive types or generic types either. As in the following code:

//Define Class< T > type ... 

Object e = new Object();

if(e instanceof T) {
  // Do something.
}

The error is: Cannot perform instanceof check against type parameter T. Use it's erasure Object instead since further generic type information will be erased at runtime.

Does not compile due to type erasure removing the runtime reference. However, the code below will compile:

if( type.isAssignableFrom(e.getClass())){
  // Do something.
}

Another spin on this topic. The below script displays a few days around the current, with day-of-week prefix.

At the core is the standalone :dpack routine that encodes the date into a value whose modulo 7 reveals the day-of-week per ISO 8601 standards (Mon == 0). Also provided is :dunpk which is the inverse function:

@echo off& setlocal enabledelayedexpansion

rem Example of date manipulation within a .BAT file.
rem This is accomplished by first packing the date into a single number.
rem This demo .bat displays dates surrounding the current date, prefixed
rem with the day-of-week.

I've searched around, and only this solution helped me:

mysql -u root -p

set global net_buffer_length=1000000; --Set network buffer length to a large byte number

set global max_allowed_packet=1000000000; --Set maximum allowed packet size to a large byte number

SET foreign_key_checks = 0; --Disable foreign key checking to avoid delays,errors and unwanted behaviour

source file.sql --Import your sql dump file

SET foreign_key_checks = 1; --Remember to enable foreign key checks when procedure is complete!

The answer is found here.

As it says, it is ambiguous. Your array comparison returns a boolean array. Methods any() and all() reduce values over the array (either logical_or or logical_and). Moreover, you probably don't want to check for equality. You should replace your condition with:

np.allclose(A.dot(eig_vec[:,col]), eig_val[col] * eig_vec[:,col])

In most cases you want simple ArrayList - an implementation of List

Before JDK version 7

List<String> list = new ArrayList<String>();

JDK 7 and later you can use the diamond operator

List<String> list = new ArrayList<>();

Note that it will choke when passed the dubious "0]" command name and will also fail to identify processes having an embedded space in their names.

Note too that the most upvoted and accepted solution demands non portable ps options and gratuitously uses a shell that is, despite its popularity, not guaranteed to be present on every Unix/Linux machine (bash)

Here is a great simple dynamic breadcrumb (tweak as needed):

    <?php 
    $docroot = "/zen/index5.php";
    $path =($_SERVER['REQUEST_URI']);
    $names = explode("/", $path); 
    $trimnames = array_slice($names, 1, -1);
    $length = count($trimnames)-1;
    $fixme = array(".php","-","myname");
    $fixes = array(""," ","My<strong>Name</strong>");
    echo '<div id="breadwrap"><ol id="breadcrumb">';
    $url = "";
    for ($i = 0; $i <= $length;$i++){
    $url .= $trimnames[$i]."/";
        if($i>0 && $i!=$length){
            echo '<li><a href="/'.$url.'">'.ucfirst(str_replace($fixme,$fixes,$trimnames[$i]) . ' ').'</a></li>';
    }
    elseif ($i == $length){
        echo '<li class="current">'.ucfirst(str_replace($fixme,$fixes,$trimnames[$i]) . ' ').'</li>';       
    }
    else{
        echo $trimnames[$i]='<li><a href='.$docroot.' id="bread-home"><span>&nbsp;</span></a></li>';
    }
}
echo '</ol>';
?>

if you are talking about just types, as other people said, parseInt() etc will return the correct type. Also, if for any reason the value could be both a number or a string and you don't want to call parseInt(), typeof expressions will also cast to the correct type:

function f(value:number|string){
  if(typeof value==='number'){
   // value : number
  }else {
   // value : string
  }
}

You can use *args and **kwargs syntax for variable length arguments.

What do *args and **kwargs mean?

And from the official python tutorial

http://docs.python.org/dev/tutorial/controlflow.html#more-on-defining-functions

Don't forget to include <typeinfo>

I believe what you are referring to is runtime type identification. You can achieve the above by doing .

#include <iostream>
#include <typeinfo>

using namespace std;

int main() {
  int i;
  cout << typeid(i).name();
  return 0;
}

This is an issue of selector specificity. (The selector .selected is less specific than ul.nav li.)

To fix, use as much specificity in the overriding rule as in the original:

ul.nav li {
 background-color:blue;
}
ul.nav li.selected {
 background-color:red;
}

You might also consider nixing the ul, unless there will be other .navs. So:

.nav li {
 background-color:blue;
}
.nav li.selected {
 background-color:red;
}

That's a bit cleaner, less typing, and fewer bits.

I couldn't used android:anyDensity="true" because objects in my game would be positioned completely different... seems this also does the trick:

// creating locale
Locale locale2 = new Locale(loc); 
Locale.setDefault(locale2);
Configuration config2 = new Configuration();
config2.locale = locale2;

// updating locale
mContext.getResources().updateConfiguration(config2, null);

The project you have downloaded compiles into a dll assembly and provide a set of classes with implemented functionality.

You should add to your solution a new project with Output Type of either Console Application or Windows Application (VS Add Project wizard will offer you different templates of Projects).

In the newly added project, you can implement logic to test your Class Library.

Output type of the project you can find and change by the following steps:

1. Right click on project in Solution Explorer -> Properties.

2. In opened tab with properties select Application and there will be ComboBox marked with Output Type label.

You can always use Block UI jQuery plugin which does everything for you, and it even blocks the page of any input while the ajax is loading. In case that the plugin seems to not been working, you can read about the right way to use it in this answer. Check it out.

You can convert your readable stream to a buffer and integrate it in your code in an asynchronous way like this.

async streamToBuffer (stream) {
    return new Promise((resolve, reject) => {
      const data = [];

      stream.on('data', (chunk) => {
        data.push(chunk);
      });

      stream.on('end', () => {
        resolve(Buffer.concat(data))
      })

      stream.on('error', (err) => {
        reject(err)
      })
   
    })
  }

the usage would be as simple as:

 // usage
  const myStream // your stream
  const buffer = await streamToBuffer(myStream) // this is a buffer

I came here hoping to find a way to get the sum across all columns in a data table and run into issues implementing the above solutions. A way to add a column with the sum across all columns uses the cbind function:

cbind(data, total = rowSums(data))

This method adds a total column to the data and avoids the alignment issue yielded when trying to sum across ALL columns using the above solutions (see the post below for a discussion of this issue).

Adding a new column to matrix error

Simple definitions for overloading and overriding

Overloading (Compile Time Polymorphism):: Functions with same name and different parameters

public class A
{
    public void print(int x, int y)
    {
        Console.WriteLine("Parent Method");
    }
}

public class B : A
{
    public void child()
    {
        Console.WriteLine("Child Method");

    public void print(float x, float y)
    {
        Console.WriteLine("Overload child method");
    }
}

Overriding (Run Time Polymorphism):: Functions in the extended class with same name and same parameters as in the base class, but with different behaviors.

public class A
{
    public virtual void print()
    {
        Console.WriteLine("Parent Method");
    }
}

public class B : A

YES - solution is to save workbook in to XML file (eg. 'XML Spreadsheet 2003') and edit this file as text in notepad! use "SEARCH" function of notepad to find query text and change your data to "?".

save and open in excel, try refresh data and excel will be monit about parameters.

You can pass in the element to the controller, just like the scope:

function someControllerFunc($scope, $element){

}

Please use the below code and let me know

try{

            Class.forName("com.mysql.jdbc.Driver").newInstance();
            con = DriverManager.getConnection(c, "root", "MyNewPass");
            System.out.println("connection done");


            PreparedStatement ps=con.prepareStatement(q);
            System.out.println(q);
            rs=ps.executeQuery();
            System.out.println("done2");
            while (rs.next()) {
               System.out.println(rs.getString(1));
               System.out.println(rs.getString(2));

            }

         response.sendRedirect("myfolder/welcome.jsp"); // wherever you wanna redirect this page.

        }
            catch (Exception e) {
                // TODO: handle exception
                System.out.println("Failed");
            }

myfolder/welcome.jsp is the relative path of your jsp page. So, change it as per your jsp page path.

If you are looking for 1st Number with decimal as string has correct decimal places, you may try regexp_substr function like this:

regexp_substr('stack12.345overflow', '\.*[[:digit:]]+\.*[[:digit:]]*')

I recently discovered q:. It opens the "command window" and shows your most recent ex-mode (command-mode) commands. You can move as usual within the window, and pressing <CR> executes the command. You can edit, etc. too. Priceless when you're messing around with some complex command or regex and you don't want to retype the whole thing, or if the complex thing you want to do was 3 commands back. It's almost like bash's set -o vi, but for vim itself (heh!).

See :help q: for more interesting bits for going back and forth.

A very simple way if your code is in Python, where I didn't have to install a Python package, is the following:

\documentclass[11pt]{article}  
\usepackage{pythonhighlight}

\begin{document}

The following is some Python code

\begin{python}
# A comment
x = [5, 7, 10]
y = 0

for num in x:
    y += num
    
print(y)
\end{python}

\end{document}

which looks like:

Unfortunately, this only works for Python.

I came across this issue myself. I had the need to conditionally validate parts of a form while the form was being constructed based on steps (i.e. certain inputs were dynamically appended during runtime). As a result, sometimes a select dropdown would need validation, and sometimes it would not. However, by the end of the ordeal, it needed to be validated. As a result, I needed a robust method which was not a workaround. I consulted the source code for jquery.validate.

Here is what I came up with:

function clearValidation(formElement){
 //Internal $.validator is exposed through $(form).validate()
 var validator = $(formElement).validate();
 //Iterate through named elements inside of the form, and mark them as error free
 $('[name]',formElement).each(function(){
   validator.successList.push(this);//mark as error free
   validator.showErrors();//remove error messages if present
 });
 validator.resetForm();//remove error class on name elements and clear history
 validator.reset();//remove all error and success data
}
//used
var myForm = document.getElementById("myFormId");
clearValidation(myForm);

$.fn.clearValidation = function(){var v = $(this).validate();$('[name]',this).each(function(){v.successList.push(this);v.showErrors();});v.resetForm();v.reset();};
//used:
$("#formId").clearValidation();

after all these good examples adam shankman still can't make sense of it. I think you should open up some code and try it. The second you try a myStack.Push(1) and myStack.Pop(1) you really should get the picture. But by the looks of it, even that will be a challenge for you!

You can disable port 80 and 443 as alternative incoming connections in Skype settings - Advanced settings - Connection.

Subquery giving dates. We are not linking with the model. So below query solves the problem.

If there are duplicate dates/model can be avoided by the following query.

select t.model, t.date
from doc t
inner join (select model, max(date) as MaxDate from doc  group by model)
tm on t.model = tm.model and t.date = tm.MaxDate

   <tbody  *ngFor="let defect of items">            
          <tr>
            <td>{{defect.param1}}</td>
            <td>{{defect.param2}}</td>
            <td>{{defect.param3}}</td>                
            <td>{{defect.param4}}</td>
            <td>{{defect.param5}} </td>
            <td>{{defect.param6}}</td>
            <td>{{defect.param7}}</td>           
          </tr>
          <tr>
            <td> <strong> Notes:</strong></td>
            <td colspan="6"> {{defect.param8}}
            </td>`enter code here`
          </tr>          
        </tbody>

The problem is that you are trying to access the element before it exists. You need to wait for the page to be fully loaded. A possible approach is to use the onload handler:

window.onload = function () {
    var e = document.getElementById("db_info");
    e.innerHTML='Found you';
};

Most common JavaScript libraries provide a DOM-ready event, though. This is better, since window.onload waits for all images, too. You do not need that in most cases.

Another approach is to place the script tag right before your closing </body>-tag, since everything in front of it is loaded at the time of execution, then.

You can disable auto-completion as of HTML5 (via autocomplete="off"), but you CAN'T override the browser's highlighting. You could try messing with ::selection in CSS (most browsers require a vendor prefix for that to work), but that probably won't help you either.

Unless the browser vendor specifically implemented a vendor-specific way of overriding it, you can't do anything about such styles that are already intended to override the site's stylesheet for the user. These are usually applied after your stylesheets are applied and ignore ! important overrides, too.

Using an && expression to join two comparisons is simply the most elegant way to do this. If you try using fancy extension methods and such, you run into the question of whether to include the upper bound, the lower bound, or both. Once you start adding additional variables or changing the extension names to indicate what is included, your code becomes longer and harder to read (for the vast majority of programmers). Furthermore, tools like Resharper will warn you if your comparison doesn't make sense (number > 100 && number < 1), which they won't do if you use a method ('i.IsBetween(100, 1)').

The only other comment I'd make is that if you're checking inputs with the intention to throw an exception, you should consider using code contracts:

Contract.Requires(number > 1 && number < 100)

This is more elegant than if(...) throw new Exception(...), and you could even get compile-time warnings if someone tries to call your method without ensuring that the number is in bounds first.

I wasn't able to make it work with migration script so I went ahead with this solution. Enter rails console using the terminal:

rails c

Type

ActiveRecord::Migration.drop_table(:tablename)

It works well for me. This will remove the previous table. Don't forget to run

rails db:migrate

Use a bytearray:

>>> frame = bytearray()
>>> frame.append(0xA2)
>>> frame.append(0x01)
>>> frame.append(0x02)
>>> frame.append(0x03)
>>> frame.append(0x04)
>>> frame
bytearray(b'\xa2\x01\x02\x03\x04')

or, using your code but fixing the errors:

frame = b""
frame += b'\xA2' 
frame += b'\x01' 
frame += b'\x02' 
frame += b'\x03'
frame += b'\x04'

A linear search starts at the beginning of a list of values, and checks 1 by 1 in order for the result you are looking for.

A binary search starts in the middle of a sorted array, and determines which side (if any) the value you are looking for is on. That "half" of the array is then searched again in the same fashion, dividing the results in half by two each time.

The previous version, xlrd 1.2.0, may appear to work, but it could also expose you to potential security vulnerabilities. With that warning out of the way, if you still want to give it a go, type the following command:

pip install xlrd==1.2.0

Second case is also inefficient in terms of String pool, you have to explicitly call intern() on return reference to make it intern.

Dictionary<int,string> comboSource = new Dictionary<int,string>();
comboSource.Add(1, "Sunday");
comboSource.Add(2, "Monday");

Aftr adding values to Dictionary, use this as combobox datasource:

comboBox1.DataSource = new BindingSource(comboSource, null);
comboBox1.DisplayMember = "Value";
comboBox1.ValueMember = "Key";

I think you could do it by creating parameters in an object maybe?

var myObject = {}; for(var i=0;i<myArray.length;i++) {     myObject[ myArray[i] ]; } 

If you don't set them to anything, you'll just have an object with some parameters that are undefined. I'd have to write this myself to be sure though.

I recommend using tqdm - https://pypi.python.org/pypi/tqdm - which makes it simple to turn any iterable or process into a progress bar, and handles all messing about with terminals needed.

From the documentation: "tqdm can easily support callbacks/hooks and manual updates. Here’s an example with urllib"

import urllib
from tqdm import tqdm

def my_hook(t):
  """
  Wraps tqdm instance. Don't forget to close() or __exit__()
  the tqdm instance once you're done with it (easiest using `with` syntax).

  Example
  -------

  >>> with tqdm(...) as t:
  ...     reporthook = my_hook(t)
  ...     urllib.urlretrieve(..., reporthook=reporthook)

  """
  last_b = [0]

  def inner(b=1, bsize=1, tsize=None):
    """
    b  : int, optional
        Number of blocks just transferred [default: 1].
    bsize  : int, optional
        Size of each block (in tqdm units) [default: 1].
    tsize  : int, optional
        Total size (in tqdm units). If [default: None] remains unchanged.
    """
    if tsize is not None:
        t.total = tsize
    t.update((b - last_b[0]) * bsize)
    last_b[0] = b
  return inner

eg_link = 'http://www.doc.ic.ac.uk/~cod11/matryoshka.zip'
with tqdm(unit='B', unit_scale=True, miniters=1,
          desc=eg_link.split('/')[-1]) as t:  # all optional kwargs
    urllib.urlretrieve(eg_link, filename='/dev/null',
                       reporthook=my_hook(t), data=None)

You have two ways of ignoring files:

• .gitignore in any folder will ignore the files as specified in the file for that folder. Using wildcards is possible.
• .git/info/exclude holds the global ignore pattern, similar to the global-ignores in subversions configuration file.

Lazy man can use this lib, Just import inside your project and

ImageView mImageView;
PhotoViewAttacher mAttacher;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    // Any implementation of ImageView can be used!
    mImageView = (ImageView) findViewById(R.id.iv_photo);

    // Set the Drawable displayed
    Drawable bitmap = getResources().getDrawable(R.drawable.wallpaper);
    mImageView.setImageDrawable(bitmap);

    // Attach a PhotoViewAttacher, which takes care of all of the zooming functionality.
    mAttacher = new PhotoViewAttacher(mImageView);
}


// If you later call mImageView.setImageDrawable/setImageBitmap/setImageResource/etc then you just need to call
mAttacher.update();

This works for me:

var result = $('#SubjectID option')
            .filter(function () 
             { return $(this).html() == "English"; }).val();

The result variable will return the index of the matched text value. Now I will just set it using it's index:

$('#SubjectID').val(result);

Just use CR to go to beginning of the line.

import time
for x in range (0,5):  
    b = "Loading" + "." * x
    print (b, end="\r")
    time.sleep(1)

My version of renaming mass files:

for i in *; do
    echo "mv $i $i"

sed -e "s#from_pattern#to_pattern#g” > result1.sh
sh result1.sh

Use the somewhat hidden security feature:

pip install requests[security] or pip install pyOpenSSL ndg-httpsclient pyasn1

Both commands install following extra packages:

• pyOpenSSL
• cryptography
• idna

Please note that this is not required for python-2.7.9+.

If pip install fails with errors, check whether you have required development packages for libffi, libssl and python installed in your system using distribution's package manager:

• Debian/Ubuntu - python-dev libffi-dev libssl-dev packages.

• Fedora - openssl-devel python-devel libffi-devel packages.

Distro list above is incomplete.

Workaround (see the original answer by @TomDotTom):

In case you cannot install some of the required development packages, there's also an option to disable that warning:

import requests.packages.urllib3
requests.packages.urllib3.disable_warnings()

If your pip itself is affected by InsecurePlatformWarning and cannot install anything from PyPI, it can be fixed with this step-by-step guide to deploy extra python packages manually.

So, I know this is an old topic, but I'll first say it isn't possible. The closest thing currently is locking the mouse to a single position, and tracking change in its x and y. This concept has been adopted by - it looks like - Chrome and Firefox. It's managed by what's called Mouse Lock, and hitting escape will break it. From my brief read-up, I think the idea is that it locks the mouse to one location, and reports motion events similar to click-and-drag events.

Here's the release documentation:
FireFox: https://developer.mozilla.org/en-US/docs/Web/API/Pointer_Lock_API
Chrome: http://www.chromium.org/developers/design-documents/mouse-lock

And here's a pretty neat demonstration: http://media.tojicode.com/q3bsp/

just seperate the class name with a comma.

.a,.b{
your styles
}

A good way to avoid loading multiple CSS files or to have inline CSS is to hand a class to the body tag depending on the version of Internet Explorer. If you only need general IE hacks, you can do something like this, but it can be extended to be version specific:

<!--[if IE ]><body class="ie"><![endif]-->
<!--[if !IE]>--><body><!--<![endif]-->

Now in your css code, you can simply do:

.ie .abc {
  position:absolute;
  left:30;
  top:-10;
}

This also keeps your CSS files valid, as you do not have to use dirty (and invalid) CSS hacks.

A short example what is the difference between @Scope("singleton") (default) and @Scope("prototype"):

DAO class:

package com.example.demo;

public class Manager {
    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

Configuration:

@Configuration
public class AppConfiguration {
    @Bean
    @Scope("singleton")
    public Manager getManager(){
        return new Manager();
    }
}

and MainApp:

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
        AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext();
        context.scan("com.example.demo");
        context.refresh();

        Manager firstManager = context.getBean(Manager.class);
        firstManager.setName("Karol");

        Manager secondManager = context.getBean(Manager.class);
        System.out.println(secondManager.getName());
    }

}

In this example the result is: Karol even if we set this name only for firstManager object. It's because Spring IoC container created one instance of object. However when we change scope to @Scope("prototype") in Configuration class then result is: null because Spring IoC container creates a new bean instance of the object when request for that bean is made.

We can use following code

textBox1.DataBindings.Add("Text", model, "Name", false, DataSourceUpdateMode.OnPropertyChanged);

Where

• "Text" – the property of textbox
• model – the model object enter code here
• "Name" – the value of model which to bind the textbox.

I try to add following code:

private static final int MY_CAMERA_REQUEST_CODE = 100;

@RequiresApi(api = Build.VERSION_CODES.M)

if (checkSelfPermission(Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) {
        requestPermissions(new String[]{Manifest.permission.CAMERA}, MY_CAMERA_REQUEST_CODE);
    }

On onCreate Function and this following code:

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    if (requestCode == MY_CAMERA_REQUEST_CODE) {
        if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            Toast.makeText(this, "camera permission granted", Toast.LENGTH_LONG).show();
        } else {
            Toast.makeText(this, "camera permission denied", Toast.LENGTH_LONG).show();
        }
    }
}

And this worked for me :)

in my case,

i'm using macOS Mojave (Apache/2.4.34). There was an issue in virtual host settings at /etc/apache2/extra/httpd-vhosts.conf file. after adding the required directory tag my problem was gone.

Hope the full virtual host setup structure will save you.

<VirtualHost *:80>
    DocumentRoot "/Users/vagabond/Sites/MainProjectFolderName/public/"
    ServerName project.loc

You really can't display 3 columns of data as a 'surface'. Only having one column of 'Z' data will give you a line in 3 dimensional space, not a surface (Or in the case of your data, 3 separate lines). For Excel to be able to work with this data, it needs to be formatted as shown below:

      13    21   29      37    45   
1000  75.2                              
1000       79.21                            
1000             80.02                      
5000             87.9                   
5000                    88.54               
5000                           88.56            
10000            90.11      
10000                   90.79   
10000                          90.87

Then, to get an actual surface, you would need to fill in all the missing cells with the appropriate Z-values. If you don't have those, then you are better off showing this as 3 separate 2D lines, because there isn't enough data for a surface.

The best 3D representation that Excel will give you of the above data is pretty confusing:

Representing this limited dataset as 2D data might be a better choice:

As a note for future reference, these types of questions usually do a little better on superuser.com.

You can use pathlib.

For Python 3.5 and above:

from pathlib import Path
contents = Path(file_path).read_text()

For older versions of Python use pathlib2:

$ pip install pathlib2

Then:

from pathlib2 import Path
contents = Path(file_path).read_text()

This is the actual read_text implementation:

def read_text(self, encoding=None, errors=None):
    """
    Open the file in text mode, read it, and close the file.
    """
    with self.open(mode='r', encoding=encoding, errors=errors) as f:
        return f.read()

Another way to do this is by using a "configure" script. If you are already using one with your makefile, you can use a combination of uname and sed to get things to work out. First, in your script, do:

UNAME=uname

Then, in order to put this in your Makefile, start out with Makefile.in which should have something like

UNAME=@@UNAME@@

in it.

Use the following sed command in your configure script after the UNAME=uname bit.

sed -e "s|@@UNAME@@|$UNAME|" < Makefile.in > Makefile

Now your makefile should have UNAME defined as desired. If/elif/else statements are all that's left!

If you have a pandas serie with NaN, and want to remove it (without loosing index):

serie = serie.dropna()

# create data for example
data = np.array(['g', 'e', 'e', 'k', 's']) 
ser = pd.Series(data)
ser.replace('e', np.NAN)
print(ser)

0      g
1    NaN
2    NaN
3      k
4      s
dtype: object

# the code
ser = ser.dropna()
print(ser)

0    g
3    k
4    s
dtype: object

ULs don't have a name attribute, but you can reference the ul by tag name.

Try replacing line 3 in your script with this:

var sub = cat.getElementsByTagName("UL");

Here is a method using String.charAt():

String str = "India";
System.out.println("last char = " + str.charAt(str.length() - 1));

The resulting output is last char = a.

I think it's too late to answer this question but I faced the same problem recently my use case was to call the paginated JSON API and get all the data from each pagination and append it to a single array.

const https = require('https');
const apiUrl = "https://example.com/api/movies/search/?Title=";
let finaldata = [];
let someCallBack = function(data){
  finaldata.push(...data);
  console.log(finaldata);
};
const getData = function (substr, pageNo=1, someCallBack) {

  let actualUrl = apiUrl + `${substr}&page=${pageNo}`;
  let mydata = []
  https.get(actualUrl, (resp) => {
    let data = '';
    resp.on('data', (chunk) => {
        data += chunk;
    });
    resp.on('end', async () => {
        if (JSON.parse(data).total_pages!==null){
          pageNo+=1;
          somCallBack(JSON.parse(data).data);
          await getData(substr, pageNo, someCallBack);
        }
    });
  }).on("error", (err) => {
      console.log("Error: " + err.message);
  });
}

getData("spiderman", pageNo=1, someCallBack);

Like @ackuser mentioned we can use other module but In my use case I had to use the node https. Hoping this will help others.

You can try something like this-

as.vector(unlist(aframe$a2))

For Jersey 2.*:

Client client = ClientBuilder.newBuilder()
                .hostnameVerifier(new HostnameVerifier() {

                    public boolean verify(String hostname, SSLSession session) {
                        return true;
                    }
                }).build();

It is possible due to using MVC controller instead of Web API controller. Check the namespace in Web API controller it should be as following

using System.Net;
using System.Net.Http;
using System.Web.Http;

If the namespace are as following then it is give above error in web api controller method calling

using System.Web;
using System.Web.Mvc;

There are different ways to do that.

• I created the data frame to showcase the different techniques to filter your data.

df = pd.DataFrame({'Date':['01-Jun-13','03-Jun-13', '15-Aug-13', '20-Jan-14', '21-Feb-14'],

'abc':[100,-20,40,25,60],'xyz':[200,50,-5,15,80] })

• I separated months/year/day and seperated month-year as you explained.

def getMonth(s):
  return s.split("-")[1]

def getDay(s):
  return s.split("-")[0]

def getYear(s):
  return s.split("-")[2]

def getYearMonth(s):
  return s.split("-")[1]+"-"+s.split("-")[2]

• I created new columns: year, month, day and 'yearMonth'. In your case, you need one of both. You can group using two columns 'year','month' or using one column yearMonth

df['year']= df['Date'].apply(lambda x: getYear(x))
df['month']= df['Date'].apply(lambda x: getMonth(x))
df['day']= df['Date'].apply(lambda x: getDay(x))
df['YearMonth']= df['Date'].apply(lambda x: getYearMonth(x))

Output:

        Date  abc  xyz year month day YearMonth
0  01-Jun-13  100  200   13   Jun  01    Jun-13
1  03-Jun-13  -20   50   13   Jun  03    Jun-13
2  15-Aug-13   40   -5   13   Aug  15    Aug-13
3  20-Jan-14   25   15   14   Jan  20    Jan-14
4  21-Feb-14   60   80   14   Feb  21    Feb-14

• You can go through the different groups in groupby(..) items.

In this case, we are grouping by two columns:

for key,g in df.groupby(['year','month']):
    print key,g

Output:

('13', 'Jun')         Date  abc  xyz year month day YearMonth
0  01-Jun-13  100  200   13   Jun  01    Jun-13
1  03-Jun-13  -20   50   13   Jun  03    Jun-13
('13', 'Aug')         Date  abc  xyz year month day YearMonth
2  15-Aug-13   40   -5   13   Aug  15    Aug-13
('14', 'Jan')         Date  abc  xyz year month day YearMonth
3  20-Jan-14   25   15   14   Jan  20    Jan-14
('14', 'Feb')         Date  abc  xyz year month day YearMonth

In this case, we are grouping by one column:

for key,g in df.groupby(['YearMonth']):
    print key,g

Output:

Jun-13         Date  abc  xyz year month day YearMonth
0  01-Jun-13  100  200   13   Jun  01    Jun-13
1  03-Jun-13  -20   50   13   Jun  03    Jun-13
Aug-13         Date  abc  xyz year month day YearMonth
2  15-Aug-13   40   -5   13   Aug  15    Aug-13
Jan-14         Date  abc  xyz year month day YearMonth
3  20-Jan-14   25   15   14   Jan  20    Jan-14
Feb-14         Date  abc  xyz year month day YearMonth
4  21-Feb-14   60   80   14   Feb  21    Feb-14

• In case you wanna access to specific item, you can use get_group

print df.groupby(['YearMonth']).get_group('Jun-13')

Output:

        Date  abc  xyz year month day YearMonth
0  01-Jun-13  100  200   13   Jun  01    Jun-13
1  03-Jun-13  -20   50   13   Jun  03    Jun-13

• Similar to get_group. This hack would help to filter values and get the grouped values.

This also would give the same result.

print df[df['YearMonth']=='Jun-13'] 

Output:

        Date  abc  xyz year month day YearMonth
0  01-Jun-13  100  200   13   Jun  01    Jun-13
1  03-Jun-13  -20   50   13   Jun  03    Jun-13

You can select list of abc or xyz values during Jun-13

print df[df['YearMonth']=='Jun-13'].abc.values
print df[df['YearMonth']=='Jun-13'].xyz.values

Output:

[100 -20]  #abc values
[200  50]  #xyz values

You can use this to go through the dates that you have classified as "year-month" and apply cretiria on it to get related data.

for x in set(df.YearMonth): 
    print df[df['YearMonth']==x].abc.values
    print df[df['YearMonth']==x].xyz.values

I recommend also to check this answer as well.

First of all you should change database structure - the score in this case is some kind of composite value and should be stored in two columns, eg. score_host, score_guest.

MySQL doesn't provide explode() equivalent however in this case you could use SUBSTRING() and LOCATE() to cut off score of a host and a guest.

SELECT 
   CONVERT(SUBSTRING(score, 1, LOCATE('-',score) - 2) USING INTEGER) as score_host,
   CONVERT(SUBSTRING(score, LOCATE('-',score)+2) USING INTEGER) as score_guest
FROM ...;

CONVERT() is used to cast a string "23" into number 23.

request.getRequestURI().substring(request.getContextPath().length())

I just encounter a similar case with this one, but the solution here seems not helping me. So I try to figure it out by myself. I work out the week start date only, week end date should be of similar logic.

Select 
      Sum(NumberOfBrides) As [Wedding Count], 
      DATEPART( wk, WeddingDate) as [Week Number],
      DATEPART( year, WeddingDate) as [Year],
      DATEADD(DAY, 1 - DATEPART(WEEKDAY, dateadd(wk, DATEPART( wk, WeddingDate)-1,  DATEADD(yy,DATEPART( year, WeddingDate)-1900,0))), dateadd(wk, DATEPART( wk, WeddingDate)-1, DATEADD(yy,DATEPART( year, WeddingDate)-1900,0))) as [Week Start]

FROM  MemberWeddingDates
Group By DATEPART( year, WeddingDate), DATEPART( wk, WeddingDate)
Order By Sum(NumberOfBrides) Desc

campaign is a comprehensive solution for sending emails in Node, and it comes with a very simple API.

You instance it like this.

var client = require('campaign')({
  from: '[email protected]'
});

To send emails, you can use Mandrill, which is free and awesome. Just set your API key, like this:

process.env.MANDRILL_APIKEY = '<your api key>';

_{(if you want to send emails using another provider, check the docs)}

Then, when you want to send an email, you can do it like this:

client.sendString('<p>{{something}}</p>', {
  to: ['[email protected]', '[email protected]'],
  subject: 'Some Subject',
  preview': 'The first line',
  something: 'this is what replaces that thing in the template'
}, done);

The GitHub repo has pretty extensive documentation.

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
driver.get("http://example.com")

Select element by id:

inputElement = driver.find_element_by_id("a1")
inputElement.send_keys('1')

Now you can simulate hitting ENTER:

inputElement.send_keys(Keys.ENTER)

or if it is a form you can submit:

The reason your URL is being rewritten to file///K:/AmberCRO%20SOP/2011-07-05/SOP-SOP-3.0.pdf is because you specified http://file://

The http:// at the beginning is the protocol being used, and your browser is stripping out the second colon (:) because it is invalid.

Note

If you link to something like

<a href="file:///K:/yourfile.pdf">yourfile.pdf</a>

The above represents a link to a file called k:/yourfile.pdf on the k: drive on the machine on which you are viewing the URL.

You can do this, for example the below creates a link to C:\temp\test.pdf

<a href="file:///C:/Temp/test.pdf">test.pdf</a>

By specifying file:// you are indicating that this is a local resource. This resource is NOT on the internet.

Most people do not have a K:/ drive.

But, if this is what you are trying to achieve, that's fine, but this is not how a "typical" link on a web page works, and you shouldn't being doing this unless everyone who is going to access your link has access to the (same?) K:/drive (this might be the case with a shared network drive).

You could try

<a href="file:///K:/AmberCRO-SOP/2011-07-05/SOP-SOP-3.0.pdf">test.pdf</a>
<a href="AmberCRO-SOP/2011-07-05/SOP-SOP-3.0.pdf">test.pdf</a>
<a href="2011-07-05/SOP-SOP-3.0.pdf">test.pdf</a>

Note that http://file:///K:/AmberCRO%20SOP/2011-07-05/SOP-SOP-3.0.pdf is a malformed

How and where is app.run() used? After module definition or after app.config(), after app.controller()?

Where:

In your package.js E.g. /packages/dashboard/public/controllers/dashboard.js

How:

Make it look like this

var app = angular.module('mean.dashboard', ['ui.bootstrap']);

app.controller('DashboardController', ['$scope', 'Global', 'Dashboard',
    function($scope, Global, Dashboard) {
        $scope.global = Global;
        $scope.package = {
            name: 'dashboard'
        };
        // ...
    }
]);

app.run(function(editableOptions) {
    editableOptions.theme = 'bs3'; // bootstrap3 theme. Can be also 'bs2', 'default'
});

According to the spec:

The Content-Length entity-header field indicates the size of the entity-body, in decimal number of OCTETs, sent to the recipient or, in the case of the HEAD method, the size of the entity-body that would have been sent had the request been a GET.

Content-Length    = "Content-Length" ":" 1*DIGIT

An example is

Content-Length: 3495

Applications SHOULD use this field to indicate the transfer-length of the message-body, unless this is prohibited by the rules in section 4.4.

Any Content-Length greater than or equal to zero is a valid value. Section 4.4 describes how to determine the length of a message-body if a Content-Length is not given.

Note that the meaning of this field is significantly different from the corresponding definition in MIME, where it is an optional field used within the "message/external-body" content-type. In HTTP, it SHOULD be sent whenever the message's length can be determined prior to being transferred, unless this is prohibited by the rules in section 4.4.

You can copy output from sp to temporaty table.

CREATE TABLE #GetVersionValues
(
    [Index] int,
    [Name]  sysname,
    Internal_value  int,
    Character_Value sysname
)
INSERT #GetVersionValues EXEC master.dbo.xp_msver 'WindowsVersion'
SELECT * FROM #GetVersionValues
drop TABLE #GetVersionValues

C# 6.0 adds readonly auto properties

public object MyProperty { get; }

So when you don't need to support older compilers you can have a truly readonly property with code that's just as concise as a readonly field.

Versioning:
I think it doesn't make much difference if you are only interested in source compatibility.
Using a property is better for binary compatibility since you can replace it by a property which has a setter without breaking compiled code depending on your library.

Convention:
You are following the convention. In cases like this where the differences between the two possibilities are relatively minor following the convention is better. One case where it might come back to bite you is reflection based code. It might only accept properties and not fields, for example a property editor/viewer.

Serialization
Changing from field to property will probably break a lot of serializers. And AFAIK XmlSerializer does only serialize public properties and not public fields.

Using an Autoproperty
Another common Variation is using an autoproperty with a private setter. While this is short and a property it doesn't enforce the readonlyness. So I prefer the other ones.

Readonly field is selfdocumenting
There is one advantage of the field though:
It makes it clear at a glance at the public interface that it's actually immutable (barring reflection). Whereas in case of a property you can only see that you cannot change it, so you'd have to refer to the documentation or implementation.

But to be honest I use the first one quite often in application code since I'm lazy. In libraries I'm typically more thorough and follow the convention.

pointers and references are two different thigngs.

A couple of things I have not seen mentioned.

A pointer is the address of something. A pointer can be stored and copied like any other variable. It thus have a size.

A reference should be seen as an ALIAS of something. It does not have a size and cannot be stored. It MUST reference something, ie. it cannot be null or changed. Well, sometimes the compiler needs to store the reference as a pointer, but that is an implementation detail.

With references you don't have the issues with pointers, like ownership handling, null checking, de-referencing on use.

Beautiful set of stencils from Microsoft here.

One idea:

try {
    int i = Integer.parseInt(myString);
    if (i < 0) {
        // Error, negative input
    }
} catch (NumberFormatException e) {
    // Error, not a number.
}

There is also, in commons-lang library the CharUtils class that provides the methods isAsciiNumeric() to check that a character is a number, and isAsciiAlpha() to check that the character is a letter...

After running below command it works for me

Networking code is notoriously difficult to write, test and debug.

You often have lots of things to consider such as:

• what "endian" will you use for the data that is exchanged (Intel x86/x64 is based on little-endian) - systems that use big-endian can still read data that is in little-endian (and vice versa), but they have to rearrange the data. When documenting your "protocol" just make it clear which one you are using.

• are there any "settings" that have been set on the sockets which can affect how the "stream" behaves (e.g. SO_LINGER) - you might need to turn certain ones on or off if your code is very sensitive

• how does congestion in the real world which causes delays in the stream affect your reading/writing logic

If the "message" being exchanged between a client and server (in either direction) can vary in size then often you need to use a strategy in order for that "message" to be exchanged in a reliable manner (aka Protocol).

Here are several different ways to handle the exchange:

• have the message size encoded in a header that precedes the data - this could simply be a "number" in the first 2/4/8 bytes sent (dependent on your max message size), or could be a more exotic "header"

• use a special "end of message" marker (sentinel), with the real data encoded/escaped if there is the possibility of real data being confused with an "end of marker"

• use a timeout....i.e. a certain period of receiving no bytes means there is no more data for the message - however, this can be error prone with short timeouts, which can easily be hit on congested streams.

• have a "command" and "data" channel on separate "connections"....this is the approach the FTP protocol uses (the advantage is clear separation of data from commands...at the expense of a 2nd connection)

Each approach has its pros and cons for "correctness".

The code below uses the "timeout" method, as that seems to be the one you want.

See http://msdn.microsoft.com/en-us/library/bk6w7hs8.aspx. You can get access to the NetworkStream on the TCPClient so you can change the ReadTimeout.

string SendCmd(string cmd, string ip, int port)
{
  var client = new TcpClient(ip, port);
  var data = Encoding.GetEncoding(1252).GetBytes(cmd);
  var stm = client.GetStream();
  // Set a 250 millisecond timeout for reading (instead of Infinite the default)
  stm.ReadTimeout = 250;
  stm.Write(data, 0, data.Length);
  byte[] resp = new byte[2048];
  var memStream = new MemoryStream();
  int bytesread = stm.Read(resp, 0, resp.Length);
  while (bytesread > 0)
  {
      memStream.Write(resp, 0, bytesread);
      bytesread = stm.Read(resp, 0, resp.Length);
  }
  return Encoding.GetEncoding(1252).GetString(memStream.ToArray());
}

As a footnote for other variations on this writing network code...when doing a Read where you want to avoid a "block", you can check the DataAvailable flag and then ONLY read what is in the buffer checking the .Length property e.g. stm.Read(resp, 0, stm.Length);

Not sure what you mean by "creating json manually", but you can use something like gson (http://code.google.com/p/google-gson/), and that would transform your HashMap, Array, String, etc, to a JSON value. I recommend going with a framework for this.

Ease of use

The analytic and synthetic reasons were already mentioned. For newcomers there's a more significant incentive to stop using the dated mysql_ functions.

Contemporary database APIs are just easier to use.

It's mostly the bound parameters which can simplify code. And with excellent tutorials (as seen above) the transition to PDO isn't overly arduous.

Rewriting a larger code base at once however takes time. Raison d'être for this intermediate alternative:

Equivalent pdo_* functions in place of mysql_*

Using <pdo_mysql.php> you can switch from the old mysql_ functions with minimal effort. It adds pdo_ function wrappers which replace their mysql_ counterparts.

1. Simply include_once("pdo_mysql.php"); in each invocation script that has to interact with the database.
   

2. Remove the mysql_ function prefix everywhere and replace it with pdo_.

   • mysql_connect() becomes pdo_connect()
   • mysql_query() becomes pdo_query()
   • mysql_num_rows() becomes pdo_num_rows()
   • mysql_insert_id() becomes pdo_insert_id()
   • mysql_fetch_array() becomes pdo_fetch_array()
   • mysql_fetch_assoc() becomes pdo_fetch_assoc()
   • mysql_real_escape_string() becomes pdo_real_escape_string()
   • and so on...
     
     

3. Your code will work alike and still mostly look the same:

   include_once("pdo_mysql.php"); 
   
   pdo_connect("localhost", "usrABC", "pw1234567");
   pdo_select_db("test");
   
   $result = pdo_query("SELECT title, html FROM pages");  
   
   while ($row = pdo_fetch_assoc($result)) {
       print "$row[title] - $row[html]";
   }
   

Et voilà.
Your code is using PDO.
Now it's time to actually utilize it.

Bound parameters can be easy to use

You just need a less unwieldy API.

pdo_query() adds very facile support for bound parameters. Converting old code is straightforward:

Move your variables out of the SQL string.

• Add them as comma delimited function parameters to pdo_query().
• Place question marks ? as placeholders where the variables were before.
• Get rid of ' single quotes that previously enclosed string values/variables.

The advantage becomes more obvious for lengthier code.

Often string variables aren't just interpolated into SQL, but concatenated with escaping calls in between.

pdo_query("SELECT id, links, html, title, user, date FROM articles
   WHERE title='" . pdo_real_escape_string($title) . "' OR id='".
   pdo_real_escape_string($title) . "' AND user <> '" .
   pdo_real_escape_string($root) . "' ORDER BY date")

With ? placeholders applied you don't have to bother with that:

pdo_query("SELECT id, links, html, title, user, date FROM articles
   WHERE title=? OR id=? AND user<>? ORDER BY date", $title, $id, $root)

Remember that pdo_* still allows either or.
Just don't escape a variable and bind it in the same query.

• The placeholder feature is provided by the real PDO behind it.
• Thus also allowed :named placeholder lists later.

More importantly you can pass $_REQUEST[] variables safely behind any query. When submitted <form> fields match the database structure exactly it's even shorter:

pdo_query("INSERT INTO pages VALUES (?,?,?,?,?)", $_POST);

So much simplicity. But let's get back to some more rewriting advises and technical reasons on why you may want to get rid of mysql_ and escaping.

Fix or remove any oldschool sanitize() function

Once you have converted all mysql_ calls to pdo_query with bound params, remove all redundant pdo_real_escape_string calls.

In particular you should fix any sanitize or clean or filterThis or clean_data functions as advertised by dated tutorials in one form or the other:

function sanitize($str) {
   return trim(strip_tags(htmlentities(pdo_real_escape_string($str))));
}

Most glaring bug here is the lack of documentation. More significantly the order of filtering was in exactly the wrong order.

• Correct order would have been: deprecatedly stripslashes as the innermost call, then trim, afterwards strip_tags, htmlentities for output context, and only lastly the _escape_string as its application should directly preceed the SQL intersparsing.

• But as first step just get rid of the _real_escape_string call.

• You may have to keep the rest of your sanitize() function for now if your database and application flow expect HTML-context-safe strings. Add a comment that it applies only HTML escaping henceforth.

• String/value handling is delegated to PDO and its parameterized statements.

• If there was any mention of stripslashes() in your sanitize function, it may indicate a higher level oversight.

  • That was commonly there to undo damage (double escaping) from the deprecated magic_quotes. Which however is best fixed centrally, not string by string.

  • Use one of the userland reversal approaches. Then remove the stripslashes() in the sanitize function.

  Historic note on magic_quotes. That feature is rightly deprecated. It's often incorrectly portrayed as failed security feature however. But magic_quotes are as much a failed security feature as tennis balls have failed as nutrition source. That simply wasn't their purpose.

  The original implementation in PHP2/FI introduced it explicitly with just "quotes will be automatically escaped making it easier to pass form data directly to msql queries". Notably it was accidentially safe to use with mSQL, as that supported ASCII only.
  Then PHP3/Zend reintroduced magic_quotes for MySQL and misdocumented it. But originally it was just a convenience feature, not intend for security.

How prepared statements differ

When you scramble string variables into the SQL queries, it doesn't just get more intricate for you to follow. It's also extraneous effort for MySQL to segregate code and data again.

SQL injections simply are when data bleeds into code context. A database server can't later spot where PHP originally glued variables inbetween query clauses.

With bound parameters you separate SQL code and SQL-context values in your PHP code. But it doesn't get shuffled up again behind the scenes (except with PDO::EMULATE_PREPARES). Your database receives the unvaried SQL commands and 1:1 variable values.

While this answer stresses that you should care about the readability advantages of dropping mysql_. There's occasionally also a performance advantage (repeated INSERTs with just differing values) due to this visible and technical data/code separation.

Beware that parameter binding still isn't a magic one-stop solution against all SQL injections. It handles the most common use for data/values. But can't whitelist column name / table identifiers, help with dynamic clause construction, or just plain array value lists.

Hybrid PDO use

These pdo_* wrapper functions make a coding-friendly stop-gap API. (It's pretty much what MYSQLI could have been if it wasn't for the idiosyncratic function signature shift). They also expose the real PDO at most times.
Rewriting doesn't have to stop at using the new pdo_ function names. You could one by one transition each pdo_query() into a plain $pdo->prepare()->execute() call.

It's best to start at simplifying again however. For example the common result fetching:

$result = pdo_query("SELECT * FROM tbl");
while ($row = pdo_fetch_assoc($result)) {

Can be replaced with just an foreach iteration:

foreach ($result as $row) {

Or better yet a direct and complete array retrieval:

$result->fetchAll();

You'll get more helpful warnings in most cases than PDO or mysql_ usually provide after failed queries.

Other options

So this hopefully visualized some practical reasons and a worthwile pathway to drop mysql_.

Just switching to pdo doesn't quite cut it. pdo_query() is also just a frontend onto it.

Unless you also introduce parameter binding or can utilize something else from the nicer API, it's a pointless switch. I hope it's portrayed simple enough to not further the discouragement to newcomers. (Education usually works better than prohibition.)

While it qualifies for the simplest-thing-that-could-possibly-work category, it's also still very experimental code. I just wrote it over the weekend. There's a plethora of alternatives however. Just google for PHP database abstraction and browse a little. There always have been and will be lots of excellent libraries for such tasks.

If you want to simplify your database interaction further, mappers like Paris/Idiorm are worth a try. Just like nobody uses the bland DOM in JavaScript anymore, you don't have to babysit a raw database interface nowadays.

2019 answer:

Some time has passed and I changed my approach now when building forms. I've done thousands of them till today and got really tired of typing id for every label/input pair, so this was flushed down the toilet. When you dive input right into the label, things work the same way, no ids necessary. I also took advantage of flexbox being, well, very flexible.

HTML:

<label>
  Short label <input type="text" name="dummy1" />
</label>

<label>
  Somehow longer label <input type="text" name="dummy2" />
</label>

<label>
  Very long label for testing purposes <input type="text" name="dummy3" />
</label>

CSS:

label {
  display: flex;
  flex-direction: row;
  justify-content: flex-end;
  text-align: right;
  width: 400px;
  line-height: 26px;
  margin-bottom: 10px;
}

input {
  height: 20px;
  flex: 0 0 200px;
  margin-left: 10px;
}

Fiddle DEMO

Original answer:

Use label instead of span. It's meant to be paired with inputs and preserves some additional functionality (clicking label focuses the input).

This might be exactly what you want:

HTML:

<label for="dummy1">title for dummy1:</label>
<input id="dummy1" name="dummy1" value="dummy1">

<label for="dummy2">longer title for dummy2:</label>
<input id="dummy2" name="dummy2" value="dummy2">

<label for="dummy3">even longer title for dummy3:</label>
<input id="dummy3" name="dummy3" value="dummy3">

CSS:

label {
    width:180px;
    clear:left;
    text-align:right;
    padding-right:10px;
}

input, label {
    float:left;
}

If your ISP/hosting service has installed ImageMagick and put its location in the PATH environment variable, you can find what versions are installed and where using:

<?php
echo "<pre>";
system("type -a convert");  
echo "</pre>";
?> 

proposed solution edit works if you replace the row

Set rDst = ThisWorkbook.Sheets("SomeSheet").Cells("YourCell").Resize(rSrc.Rows.Count, rSrc.Columns.Count)

with

Set rDst = ThisWorkbook.Sheets("SomeSheet").Range("YourRange").Resize(rSrc.Rows.Count, rSrc.Columns.Count)

int and double have different semantics. Consider division. 1/2 is 0, 1.0/2.0 is 0.5. In any given situation, one of those answers will be right and the other wrong.

That said, there are programming languages, such as JavaScript, in which 64-bit float is the only numeric data type. You have to explicitly truncate some division results to get the same semantics as Java int. Languages such as Java that support integer types make truncation automatic for integer variables.

In addition to having different semantics from double, int arithmetic is generally faster, and the smaller size (32 bits vs. 64 bits) leads to more efficient use of caches and data transfer bandwidth.

To the delight of font purists everywhere, the iPhone system interface uses Helvetica or a variant thereof.

The original iPhone, iPhone 3G and iPhone 3GS system interface uses Helvetica. As first noted by the always excellent DaringFireball, the iPhone 4 uses a subtly revised font called "Helvetica Neue." DaringFireball also notes that this change is related to the iPhone 4 display rather than the iOS 4 operating system and older iPhone models running iOS 4 still use Helvetica as the system font.

iPod models released prior to the iPhone use either Chicago, Espy Sans, or Myriad and use Helvetica after the release of the iPhone.

From http://www.everyipod.com/iphone-faq/iphone-who-designed-iphone-font-used-iphone-ringtones.html

For iOS9 it has changed to San Fransisco. See http://developer.apple.com/fonts for more info.

Remove ~ character in location so

becomes

If you're attempting to do this in a .NET Standard library, here's a simple solution, with all of the risks of just returning true in your handler. I leave safety up to you.

var handler = new HttpClientHandler();
handler.ClientCertificateOptions = ClientCertificateOption.Manual;
handler.ServerCertificateCustomValidationCallback = 
    (httpRequestMessage, cert, cetChain, policyErrors) =>
{
    return true;
};

var client = new HttpClient(handler);

You have to specify project_id:

reverse('edit_project', kwargs={'project_id':4})

In my case, Incorrect string value: '\xCC\x88'..., the problem was that an o-umlaut was in its decomposed state. This question-and-answer helped me understand the difference between o¨ and ö. In PHP, the fix for me was to use PHP's Normalizer library. E.g., Normalizer::normalize('o¨', Normalizer::FORM_C).

A @Component requires a view whereas a @Directive does not.

Directives

I liken a @Directive to an Angular 1.0 directive with the option restrict: 'A' (Directives aren't limited to attribute usage.) Directives add behaviour to an existing DOM element or an existing component instance. One example use case for a directive would be to log a click on an element.

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

@Directive({
    selector: "[logOnClick]",
    hostListeners: {
        'click': 'onClick()',
    },
})
class LogOnClick {
    constructor() {}
    onClick() { console.log('Element clicked!'); }
}

Which would be used like so:

<button logOnClick>I log when clicked!</button>

Components

A component, rather than adding/modifying behaviour, actually creates its own view (hierarchy of DOM elements) with attached behaviour. An example use case for this might be a contact card component:

import {Component, View} from '@angular/core';

@Component({
  selector: 'contact-card',
  template: `
    <div>
      <h1>{{name}}</h1>
      <p>{{city}}</p>
    </div>
  `
})
class ContactCard {
  @Input() name: string
  @Input() city: string
  constructor() {}
}

Which would be used like so:

<contact-card [name]="'foo'" [city]="'bar'"></contact-card>

ContactCard is a reusable UI component that we could use anywhere in our application, even within other components. These basically make up the UI building blocks of our applications.

In summary

Write a component when you want to create a reusable set of DOM elements of UI with custom behaviour. Write a directive when you want to write reusable behaviour to supplement existing DOM elements.

I used this to align everything in the center of the wrapper div in case it helps anyone - I found it simplest:

div.wrapper {_x000D_
  /* --- This works --- */_x000D_
  display: flex;_x000D_
  /* Align Vertically */_x000D_
  align-items: center;_x000D_
  /* Align Horizontally */_x000D_
  justify-content: center;_x000D_
  /* --- ---------- ----- */_x000D_
  width: 100%;_x000D_
  height:100px;_x000D_
  background-color: blue;_x000D_
}_x000D_
div.inner {_x000D_
  width: 50px;_x000D_
  height: 50px;_x000D_
  background-color: orange;_x000D_
}

<div class="wrapper">_x000D_
  <div class="inner">_x000D_
  </div>_x000D_
</div>

You can easily auto increase versionName and versionCode programmatically.

For Android add this to your gradle script and also create a file version.properties with VERSION_CODE=555

android {
        compileSdkVersion 30
        buildToolsVersion "30.0.3"
    
        def versionPropsFile = file('version.properties')
        if (versionPropsFile.canRead()) {
            def Properties versionProps = new Properties()
    
            versionProps.load(new FileInputStream(versionPropsFile))
    
            def code = versionProps['VERSION_CODE'].toInteger() + 1
    
            versionProps['VERSION_CODE'] = code.toString()
            versionProps.store(versionPropsFile.newWriter(), null)
    
    
            defaultConfig {
                applicationId "app.umanusorn.playground"
                minSdkVersion 29
                targetSdkVersion 30
                versionCode code
                versionName code.toString()

If you want to get cute, you could write an extension method that wrote an IEnumerable<object> sequence to the console. This will work with enumerables of any type, because IEnumerable<T> is covariant on T:

using System;
using System.Collections.Generic;

namespace Demo
{
    internal static class Program
    {
        private static void Main(string[] args)
        {
            string[] array  = new []{"One", "Two", "Three", "Four"};
            array.Print();

            Console.WriteLine();

            object[] objArray = new object[] {"One", 2, 3.3, TimeSpan.FromDays(4), '5', 6.6f, 7.7m};
            objArray.Print();
        }
    }

    public static class MyEnumerableExt
    {
        public static void Print(this IEnumerable<object> @this)
        {
            foreach (var obj in @this)
                Console.WriteLine(obj);
        }
    }
}

(I don't think you'd use this other than in test code.)

Based on above solutions, here comes a extension class which you can use to serialize and deserialize any object. Any other XML attributions are up to you.

Just use it like this:

        string s = new MyObject().Serialize(); // to serialize into a string
        MyObject b = s.Deserialize<MyObject>();// deserialize from a string



internal static class Extensions
{
    public static T Deserialize<T>(this string value)
    {
        var xmlSerializer = new XmlSerializer(typeof(T));

        return (T)xmlSerializer.Deserialize(new StringReader(value));
    }

    public static string Serialize<T>(this T value)
    {
        if (value == null)
            return string.Empty;

        var xmlSerializer = new XmlSerializer(typeof(T));

        using (var stringWriter = new StringWriter())
        {
            using (var xmlWriter = XmlWriter.Create(stringWriter, new XmlWriterSettings { Indent = true }))
            {
                xmlSerializer.Serialize(xmlWriter, value);
                return stringWriter.ToString();
            }
        }
    }
}

*args and **kwargs: allow you to pass a variable number of arguments to a function.

*args: is used to send a non-keyworded variable length argument list to the function:

def args(normal_arg, *argv):
    print("normal argument:", normal_arg)

    for arg in argv:
        print("Argument in list of arguments from *argv:", arg)

args('animals', 'fish', 'duck', 'bird')

Will produce:

normal argument: animals
Argument in list of arguments from *argv: fish
Argument in list of arguments from *argv: duck
Argument in list of arguments from *argv: bird

**kwargs*

**kwargs allows you to pass keyworded variable length of arguments to a function. You should use **kwargs if you want to handle named arguments in a function.

def who(**kwargs):
    if kwargs is not None:
        for key, value in kwargs.items():
            print("Your %s is %s." % (key, value))

who(name="Nikola", last_name="Tesla", birthday="7.10.1856", birthplace="Croatia")  

Will produce:

Your name is Nikola.
Your last_name is Tesla.
Your birthday is 7.10.1856.
Your birthplace is Croatia.

maybe SSL

    @Override
    public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
        // ignore ssl error
        if (handler != null){
            handler.proceed();
        } else {
            super.onReceivedSslError(view, null, error);
        }
    }

You may at times need to get different values from URL.

Below example shows different ways of extracting different parts of URL

EXAMPLE: (Sample URL)

http://localhost:60527/WebSite1test/Default2.aspx?QueryString1=1&QueryString2=2

CODE

Response.Write("<br/> " + HttpContext.Current.Request.Url.Host);
Response.Write("<br/> " + HttpContext.Current.Request.Url.Authority);
Response.Write("<br/> " + HttpContext.Current.Request.Url.Port);
Response.Write("<br/> " + HttpContext.Current.Request.Url.AbsolutePath);
Response.Write("<br/> " + HttpContext.Current.Request.ApplicationPath);
Response.Write("<br/> " + HttpContext.Current.Request.Url.AbsoluteUri);
Response.Write("<br/> " + HttpContext.Current.Request.Url.PathAndQuery);

OUTPUT

localhost
localhost:60527
60527
/WebSite1test/Default2.aspx
/WebSite1test
http://localhost:60527/WebSite1test/Default2.aspx?QueryString1=1&QueryString1=2
/WebSite1test/Default2.aspx?QueryString1=1&QueryString2=2

You can copy paste above sample code & run it in asp.net web form application with different URL.

I also recommend reading ASP.Net Routing in case you may use ASP Routing then you don't need to use traditional URL with query string.

You are trying to execute an asynchronous function in a synchronous way, which is unfortunately not possible in Javascript.

As you guessed correctly, the roomId=results.... is executed when the loading from the DB completes, which is done asynchronously, so AFTER the resto of your code is completed.

Look at this article, it talks about .insert and not .find, but the idea is the same : http://metaduck.com/01-asynchronous-iteration-patterns.html

Recursive php rename keys function:

function replaceKeys($oldKey, $newKey, array $input){
    $return = array(); 
    foreach ($input as $key => $value) {
        if ($key===$oldKey)
            $key = $newKey;

        if (is_array($value))
            $value = replaceKeys( $oldKey, $newKey, $value);

        $return[$key] = $value;
    }
    return $return; 
}

You want the "popen" function. Here's an example of running the command "ls /etc" and outputing to the console.

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


int main( int argc, char *argv[] )
{

  FILE *fp;
  char path[1035];

  /* Open the command for reading. */
  fp = popen("/bin/ls /etc/", "r");
  if (fp == NULL) {
    printf("Failed to run command\n" );
    exit(1);
  }

  /* Read the output a line at a time - output it. */
  while (fgets(path, sizeof(path), fp) != NULL) {
    printf("%s", path);
  }

  /* close */
  pclose(fp);

  return 0;
}

It's a common misconception that you can denormalise like this for performance. Use date_trunc('month', date) for your queries and add an index expression for this if you find it running slow.

Also if you need to DoubleClick and make your Form bigger/smaller , you can use the First answer, create a global int variable, add 1 every time user clicks on the component you use for dragging. If variable == 2 then make your form bigger/smaller. Also use a timer for every half a sec or a second to make your variable = 0;

The document suggests that it takes the @color/accent by default. But we can override it on code by using

fab.setBackgroundTintList(ColorStateList)

Also remember,

The minimum API version to use this library is 15 so you need to update it! if you dont want to do it then you need to define a custom drawable and decorate it!

Here it is some code:

var configuration = WebConfigurationManager.OpenWebConfiguration("~");
var section = (ConnectionStringsSection)configuration.GetSection("connectionStrings");
section.ConnectionStrings["MyConnectionString"].ConnectionString = "Data Source=...";
configuration.Save();

See more examples in this article, you may need to take a look to impersonation.
