How to POST mixed data: File, String[], String in one request.

You can use only what you need.

private String doPOST(File file, String[] array, String name) {
    RestTemplate restTemplate = new RestTemplate(true);

    //add file
    LinkedMultiValueMap<String, Object> params = new LinkedMultiValueMap<>();
    params.add("file", new FileSystemResource(file));

    //add array
    UriComponentsBuilder builder = UriComponentsBuilder.fromHttpUrl("https://my_url");
    for (String item : array) {
        builder.queryParam("array", item);
    }

    //add some String
    builder.queryParam("name", name);

    //another staff
    String result = "";
    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.MULTIPART_FORM_DATA);

    HttpEntity<LinkedMultiValueMap<String, Object>> requestEntity =
            new HttpEntity<>(params, headers);

    ResponseEntity<String> responseEntity = restTemplate.exchange(
            builder.build().encode().toUri(),
            HttpMethod.POST,
            requestEntity,
            String.class);

    HttpStatus statusCode = responseEntity.getStatusCode();
    if (statusCode == HttpStatus.ACCEPTED) {
        result = responseEntity.getBody();
    }
    return result;
}

The POST request will have File in its Body and next structure:

POST https://my_url?array=your_value1&array=your_value2&name=bob 

Ubuntu 12.04 this works...

JAVA_HOME=/usr/lib/jvm/java-6-openjdk-i386/jre

strgroupids = strgroupids.Remove(strgroupids.Length - 1);

MSDN:

String.Remove(Int32):

Deletes all the characters from this string beginning at a specified position and continuing through the last position

Yes you can; it works on Android too:

tel: phone_number
Calls the entered phone number. Valid telephone numbers as defined in the IETF RFC 3966 are accepted. Valid examples include the following:

* tel:2125551212
* tel: (212) 555 1212

The Android browser uses the Phone app to handle the “tel” scheme, as defined by RFC 3966.
Clicking a link like:

<a href="tel:2125551212">2125551212</a>

on Android will bring up the Phone app and pre-enter the digits for 2125551212 without autodialing.

Have a look to RFC3966

If you are using a MongoDB server then after using connect in the cluster clock on connect and finding the URL, the URL will be somehing like this

<mongodb+srv://Rohan:<password>@cluster0-3kcv6.mongodb.net/<dbname>?retryWrites=true&w=majority>

In this case, don't forget to replace the password with your database password and db name and then use

const client = new MongoClient(url,{useUnifiedTopology:true});

SELECT DISTINCT(firstName), ID, LastName from tableName GROUP BY firstName

Would be the best bet IMO

Put this in the HTML head section, setting the url var to the URL of the file to be downloaded:

<script type="text/javascript">  
function startDownload()  
{  
     var url='http://server/folder/file.ext';    
     window.open(url, 'Download');  
}  
</script>

Then put this in the body, which will start the download automatically after 5 seconds:

<script type="text/javascript">  
setTimeout('startDownload()', 5000); //starts download after 5 seconds  
</script> 

(From here.)

Try using the net use command in your script to map the share first, because you can provide it credentials. Then, your copy command should use those credentials.

net use \\<network-location>\<some-share> password /USER:username

Don't leave a trailing \ at the end of the

Create a Requestfactory class

import java.net.URI;

import javax.annotation.PostConstruct;

import org.apache.http.client.methods.HttpEntityEnclosingRequestBase;
import org.apache.http.client.methods.HttpUriRequest;
import org.springframework.http.HttpMethod;
import org.springframework.http.client.HttpComponentsClientHttpRequestFactory;
import org.springframework.stereotype.Component;
import org.springframework.web.client.RestTemplate;

@Component
public class RequestFactory {
    private RestTemplate restTemplate = new RestTemplate();

    @PostConstruct
    public void init() {
        this.restTemplate.setRequestFactory(new HttpComponentsClientHttpRequestWithBodyFactory());
    }

    private static final class HttpComponentsClientHttpRequestWithBodyFactory extends HttpComponentsClientHttpRequestFactory {
        @Override
        protected HttpUriRequest createHttpUriRequest(HttpMethod httpMethod, URI uri) {
            if (httpMethod == HttpMethod.GET) {
                return new HttpGetRequestWithEntity(uri);
            }
            return super.createHttpUriRequest(httpMethod, uri);
        }
    }

    private static final class HttpGetRequestWithEntity extends HttpEntityEnclosingRequestBase {
        public HttpGetRequestWithEntity(final URI uri) {
            super.setURI(uri);
        }

        @Override
        public String getMethod() {
            return HttpMethod.GET.name();
        }
    }

    public RestTemplate getRestTemplate() {
        return restTemplate;
    }
}

and @Autowired where ever you require and use, Here is one sample code GET request with RequestBody

 @RestController
 @RequestMapping("/v1/API")
public class APIServiceController {
    
    @Autowired
    private RequestFactory requestFactory;
    

    @RequestMapping(method = RequestMethod.GET, path = "/getData")
    public ResponseEntity<APIResponse> getLicenses(@RequestBody APIRequest2 APIRequest){
        APIResponse response = new APIResponse();
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_JSON);
        Gson gson = new Gson();
        try {
            StringBuilder createPartUrl = new StringBuilder(PART_URL).append(PART_URL2);
            
            HttpEntity<String> entity = new HttpEntity<String>(gson.toJson(APIRequest),headers);
            ResponseEntity<APIResponse> storeViewResponse = requestFactory.getRestTemplate().exchange(createPartUrl.toString(), HttpMethod.GET, entity, APIResponse.class); //.getForObject(createLicenseUrl.toString(), APIResponse.class, entity);
    
            if(storeViewResponse.hasBody()) {
                response = storeViewResponse.getBody();
            }
            return new ResponseEntity<APIResponse>(response, HttpStatus.OK);
        }catch (Exception e) {
            e.printStackTrace();
            return new ResponseEntity<APIResponse>(response, HttpStatus.INTERNAL_SERVER_ERROR);
        }
        
    }
}

You can use triggers.

Also check this introduction guide to triggers.

Given a list of dates dates:

Max date is max(dates)

Min date is min(dates)

Here is a very simple way (3 lines of code) using the Fullscreen API and RequestFullscreen method that I used, which is compatible across all popular browsers:

var elem = document.getElementsByTagName('video')[0];_x000D_
var fullscreen = elem.webkitRequestFullscreen || elem.mozRequestFullScreen || elem.msRequestFullscreen;_x000D_
fullscreen.call(elem); // bind the 'this' from the video object and instantiate the correct fullscreen method.

In terms of the algorithms themselves I would go with AES, for the simple reason is that it's been accepted by NIST and will be peer reviewed and cryptanalyzed for years. However I would suggest that in practical applications, unless you're storing some file that the government wants to keep secret (in which case the NSA would probably supply you with a better algorithm than both AES and Blowfish), using either of these algorithms won't make too much of a difference. All the security should be in the key, and both of these algorithms are resistant to brute force attacks. Blowfish has only shown to be weak on implementations that don't make use of the full 16 rounds. And while AES is newer, that fact should make you lean more towards BlowFish (if you were only taking age into consideration). Think of it this way, BlowFish has been around since the 90's and nobody (that we know of) has broken it yet....

Here is what I would pose to you... instead of looking at these two algorithms and trying to choose between the algorithm, why don't you look at your key generation scheme. A potential attacker who wants to decrypt your file is not going to sit there and come up with a theoretical set of keys that can be used and then do a brute force attack that can take months. Instead he is going to exploit something else, such as attacking your server hardware, reverse engineering your assembly to see the key, trying to find some config file that has the key in it, or maybe blackmailing your friend to copy a file from your computer. Those are going to be where you are most vulnerable, not the algorithm.

I guess no one mentioned this so I will write it here. In phpMyAdmin 4.x, there is "Add Routine" link under "Routines" tab at the top row. This link opens a popup dialog where you can write your Stored procedure without worrying about delimiter or template.

Add Routine

Note that for simple test stored procedure, you may want to drop the default parameter which is already given or you can simply set it with a value.

command prompt:

Try readystatechange

document.addEventListener('readystatechange', () => {    
  if (document.readyState == 'complete') codeAddress();
});

where states are:

• loading - the document is loading (no fired in snippet)
• interactive - the document is parsed, fired before DOMContentLoaded
• complete - the document and resources are loaded, fired before window.onload

<script>_x000D_
  document.addEventListener("DOMContentLoaded", () => {_x000D_
    mydiv.innerHTML += `DOMContentLoaded (timestamp: ${Date.now()})</br>`;_x000D_

Just for clarification: setRequestProperty("User-Agent", "Mozilla ...") now works just fine and doesn't append java/xx at the end! At least with Java 1.6.30 and newer.

I listened on my machine with netcat(a port listener):

$ nc -l -p 8080

It simply listens on the port, so you see anything which gets requested, like raw http-headers.

And got the following http-headers without setRequestProperty:

GET /foobar HTTP/1.1
User-Agent: Java/1.6.0_30
Host: localhost:8080
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
Connection: keep-alive

And WITH setRequestProperty:

GET /foobar HTTP/1.1
User-Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-US; rv:1.9.2.2) Gecko/20100316 Firefox/3.6.2
Host: localhost:8080
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
Connection: keep-alive

As you can see the user agent was properly set.

Full example:

import java.io.IOException;
import java.net.URL;
import java.net.URLConnection;


public class TestUrlOpener {

    public static void main(String[] args) throws IOException {
        URL url = new URL("http://localhost:8080/foobar");
        URLConnection hc = url.openConnection();
        hc.setRequestProperty("User-Agent", "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-US; rv:1.9.2.2) Gecko/20100316 Firefox/3.6.2");

        System.out.println(hc.getContentType());
    }

}

TcpClient c;

//I want to check here if port is free.
c = new TcpClient(ip, port);

...how can I first check if a certain port is free on my machine?

I mean that it is not in use by any other application. If an application is using a port others can't use it until it becomes free. – Ali

You have misunderstood what's happening here.

TcpClient(...) parameters are of server ip and server port you wish to connect to.

The TcpClient selects a transient local port from the available pool to communicate to the server. There's no need to check for the availability of the local port as it is automatically handled by the winsock layer.

In case you can't connect to the server using the above code fragment, the problem could be one or more of several. (i.e. server ip and/or port is wrong, remote server not available, etc..)

public DataSet GetDataSet()
    {
        try
        {
            DataSet dsReturn = new DataSet();
            using (SqlConnection myConnection = new SqlConnection(Core.con))
            {
                string query = "select * from table1;  select* from table2";
                SqlCommand cmd = new SqlCommand(query, myConnection);
                myConnection.Open();
                SqlDataReader reader = cmd.ExecuteReader();
                dsReturn.Load(reader, LoadOption.PreserveChanges, new string[] { "tableOne", "tableTwo" });
                return dsReturn;
            }
        }
        catch (Exception)
        {
            throw;
        }
    }

I checked for similar answer, but those given here don't fit my needs. I find something that, from my point of view, is what you're looking for. The only possible black point is a security matter (or maybe not) since I don't know about security.

I suggest using Interface (no need to use Class with constructor and so...), since you only have to create something like :

public interface ActivityClass {

    public static final String MYSTRING_1 = "STRING";

    public static final int MYINT_1 = 1;

}

Then you can access everywhere within your classes by using the following:

int myInt = ActivityClass.MYINT_1;
String myString = ActivityClass.MYSTRING_1;

The main reason is we can't create object of an interface, and IEnumerable is an interface. We need to create object of the class which implements the interface. This is the main reason we can't directly create object of IEnumerable.

Try this

<html>
    <head>
        <script type="text/javascript">
        function runProgram()
        {
            var shell = new ActiveXObject("WScript.Shell");                 
            var appWinMerge = "\"C:\\Program Files\\WinMerge\\WinMergeU.exe\" /e /s /u /wl /wr /maximize";
            var fileLeft = "\"D:\\Path\\to\\your\\file\"";
            var fileRight= "\"D:\\Path\\to\\your\\file2\"";
            shell.Run(appWinMerge + " " + fileLeft + " " + fileRight);
        }
        </script>
    </head>

ProgressDialog has become deprecated since API Level 26 https://developer.android.com/reference/android/app/ProgressDialog.html

I include a ProgressBar in my layout

   <ProgressBar
        android:layout_weight="1"
        android:id="@+id/progressBar_cyclic"
        android:visibility="gone"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:minHeight="40dp"
        android:minWidth="40dp" />

and change its visibility to .GONE | .VISIBLE depending on the use case.

    progressBar_cyclic.visibility = View.VISIBLE

If the this value you want is the just the object that you bound the event handler to, then addEventListener() already does that for you. When you do this:

productLineSelect.addEventListener('change', getSelection, false);

the getSelection function will already be called with this set to the object that the event handler was bound to. It will also be passed an argument that represents the event object which has all sorts of object information about the event.

function getSelection(event) {
    // this will be set to the object that the event handler was bound to
    // event is all the detailed information about the event
}

If the desired this value is some other value than the object you bound the event handler to, you can just do this:

var self = this;
productLineSelect.addEventListener('change',function() {
    getSelection(self)
},false);

By way of explanation:

1. You save away the value of this into a local variable in your other event handler.
2. You then create an anonymous function to pass addEventListener.
3. In that anonymous function, you call your actual function and pass it the saved value of this.

If temp_rst1.BOF and temp_rst1.EOF then the recordset is empty. This will always be true for an empty recordset, linked or local.

const regex = /myRegexp/

console.log('Hello myRegexp!'.replace(regex, 'World')) // = Hello World!

The Regex literal notation is commonly used to create new instances of RegExp

     regex needs no additional escaping
      v
/    regex   /   gm
^            ^   ^
start      end   optional modifiers

As others sugguested, you can also use the new RegExp('myRegex') constructor.
But you will have to be especially careful with escaping:

regex: 12\d45
matches: 12345

const regex = new RegExp('12\\d45')
const equalRegex = /12\d45/

I just distilled this bash function from the suggestions here:

grab() {     
  grab=$("$@")
  echo $grab
}

Then, you just do:

> grab date
Do 16. Feb 13:05:04 CET 2012
> echo $grab
Do 16. Feb 13:05:04 CET 2012

Update: an anonymous user suggested to replace echo by printf '%s\n' which has the advantage that it doesn't process options like -e in the grabbed text. So, if you expect or experience such peculiarities, consider this suggestion. Another option is to use cat <<<$grab instead.

If you change your time column into row names, then you can use as.data.frame(as.table(mat)) for simple cases like this.

Example:

data <- c(0.1, 0.2, 0.3, 0.3, 0.4, 0.5)
dimnames <- list(time=c(0, 0.5, 1), name=c("C_0", "C_1"))
mat <- matrix(data, ncol=2, nrow=3, dimnames=dimnames)
as.data.frame(as.table(mat))
  time name Freq
1    0  C_0  0.1
2  0.5  C_0  0.2
3    1  C_0  0.3
4    0  C_1  0.3
5  0.5  C_1  0.4
6    1  C_1  0.5

In this case time and name are both factors. You may want to convert time back to numeric, or it may not matter.

Logcollector is a good option but you need to install it first.

When I want to get the logfile to send by mail, I usually do the following:

• connect the device to the pc.
• Check that I already setup my os for that particular device.
• Open a terminal
• Run adb shell logcat > log.txt

Script its left and top properties as the number of pixels from the left edge and top edge respectively. It must have position: absolute;

var d = document.getElementById('yourDivId');
d.style.position = "absolute";
d.style.left = x_pos+'px';
d.style.top = y_pos+'px';

Or do it as a function so you can attach it to an event like onmousedown

function placeDiv(x_pos, y_pos) {
  var d = document.getElementById('yourDivId');
  d.style.position = "absolute";
  d.style.left = x_pos+'px';
  d.style.top = y_pos+'px';
}

ECU = EC2 Compute Unit. More from here: http://aws.amazon.com/ec2/faqs/#What_is_an_EC2_Compute_Unit_and_why_did_you_introduce_it

Amazon EC2 uses a variety of measures to provide each instance with a consistent and predictable amount of CPU capacity. In order to make it easy for developers to compare CPU capacity between different instance types, we have defined an Amazon EC2 Compute Unit. The amount of CPU that is allocated to a particular instance is expressed in terms of these EC2 Compute Units. We use several benchmarks and tests to manage the consistency and predictability of the performance from an EC2 Compute Unit. One EC2 Compute Unit provides the equivalent CPU capacity of a 1.0-1.2 GHz 2007 Opteron or 2007 Xeon processor. This is also the equivalent to an early-2006 1.7 GHz Xeon processor referenced in our original documentation. Over time, we may add or substitute measures that go into the definition of an EC2 Compute Unit, if we find metrics that will give you a clearer picture of compute capacity.

There are several ways to perform HTTP GET and POST requests:

Method A: HttpClient (Preferred)

Available in: .NET Framework 4.5+, .NET Standard 1.1+, .NET Core 1.0+ .

It is currently the preferred approach, and is asynchronous and high performance. Use the built-in version in most cases, but for very old platforms there is a NuGet package.

using System.Net.Http;

Setup

It is recommended to instantiate one HttpClient for your application's lifetime and share it unless you have a specific reason not to.

private static readonly HttpClient client = new HttpClient();

See HttpClientFactory for a dependency injection solution.

• POST

  var values = new Dictionary<string, string>
  {
      { "thing1", "hello" },
      { "thing2", "world" }
  };
  
  var content = new FormUrlEncodedContent(values);
  
  var response = await client.PostAsync("http://www.example.com/recepticle.aspx", content);
  
  var responseString = await response.Content.ReadAsStringAsync();
  

• GET

  var responseString = await client.GetStringAsync("http://www.example.com/recepticle.aspx");
  

Method B: Third-Party Libraries

RestSharp

• POST

   var client = new RestClient("http://example.com");
   // client.Authenticator = new HttpBasicAuthenticator(username, password);
   var request = new RestRequest("resource/{id}");
   request.AddParameter("thing1", "Hello");
   request.AddParameter("thing2", "world");
   request.AddHeader("header", "value");
   request.AddFile("file", path);
   var response = client.Post(request);
   var content = response.Content; // Raw content as string
   var response2 = client.Post<Person>(request);
   var name = response2.Data.Name;
  

Flurl.Http

It is a newer library sporting a fluent API, testing helpers, uses HttpClient under the hood, and is portable. It is available via NuGet.

    using Flurl.Http;

• POST

  var responseString = await "http://www.example.com/recepticle.aspx"
      .PostUrlEncodedAsync(new { thing1 = "hello", thing2 = "world" })
      .ReceiveString();
  

• GET

  var responseString = await "http://www.example.com/recepticle.aspx"
      .GetStringAsync();
  

Method C: HttpWebRequest (not recommended for new work)

Available in: .NET Framework 1.1+, .NET Standard 2.0+, .NET Core 1.0+. In .NET Core, it is mostly for compatibility -- it wraps HttpClient, is less performant, and won't get new features.

using System.Net;
using System.Text;  // For class Encoding
using System.IO;    // For StreamReader

• POST

  var request = (HttpWebRequest)WebRequest.Create("http://www.example.com/recepticle.aspx");
  
  var postData = "thing1=" + Uri.EscapeDataString("hello");
      postData += "&thing2=" + Uri.EscapeDataString("world");
  var data = Encoding.ASCII.GetBytes(postData);
  
  request.Method = "POST";
  request.ContentType = "application/x-www-form-urlencoded";
  request.ContentLength = data.Length;
  
  using (var stream = request.GetRequestStream())
  {
      stream.Write(data, 0, data.Length);
  }
  
  var response = (HttpWebResponse)request.GetResponse();
  
  var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
  

• GET

  var request = (HttpWebRequest)WebRequest.Create("http://www.example.com/recepticle.aspx");
  
  var response = (HttpWebResponse)request.GetResponse();
  
  var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
  

Method D: WebClient (Not recommended for new work)

This is a wrapper around HttpWebRequest. Compare with HttpClient.

Available in: .NET Framework 1.1+, NET Standard 2.0+, .NET Core 2.0+

using System.Net;
using System.Collections.Specialized;

• POST

  using (var client = new WebClient())
  {
      var values = new NameValueCollection();
      values["thing1"] = "hello";
      values["thing2"] = "world";
  
      var response = client.UploadValues("http://www.example.com/recepticle.aspx", values);
  
      var responseString = Encoding.Default.GetString(response);
  }
  

• GET

  using (var client = new WebClient())
  {
      var responseString = client.DownloadString("http://www.example.com/recepticle.aspx");
  }
  

What you show looks like a mesh warp. That would be straightforward using OpenGL, but "straightforward OpenGL" is like straightforward rocket science.

I wrote an iOS app for my company called Face Dancerthat's able to do 60 fps mesh warp animations of video from the built-in camera using OpenGL, but it was a lot of work. (It does funhouse mirror type changes to faces - think "fat booth" live, plus lots of other effects.)

object.runtimeType returns the type of object

For example:

print("HELLO".runtimeType); //prints String
var x=0.0;
print(x.runtimeType); //prints double

You could define a function that repeats the passed function N times.

def repeat_fun(times, f):
    for i in range(times): f()

If you want to make it even more flexible, you can even pass arguments to the function being repeated:

def repeat_fun(times, f, *args):
    for i in range(times): f(*args)

Usage:

>>> def do():
...   print 'Doing'
... 
>>> def say(s):
...   print s
... 
>>> repeat_fun(3, do)
Doing
Doing
Doing
>>> repeat_fun(4, say, 'Hello!')
Hello!
Hello!
Hello!
Hello!

I can't comment so here goes. About @David Storey answer.

Be careful on the "order of execution" in CSS3 chains! The order is right to left, not left to right.

transformation: translate(0,10%) rotate(25deg);

The rotate operation is done first, then the translate.

See: CSS3 transform order matters: rightmost operation first

//The framework handles buffering.

public void Write(Stream from, Stream to)

   for(int a = from.ReadByte(); a != -1; a = from.ReadByte())
      to.WriteByte( (byte) a );
}

/*
Note, StreamReader is an IEnumerable<Char> while Stream is an IEnumbable<byte>.
The distinction is significant such as in multiple byte character encodings

Be aware that this property isn't as useful as many people think it is. Just because your app is running on a Windows machine, for example, doesn't mean the file it's reading will be using Windows-style line separators. Many web pages contain a mixture of "\n" and "\r\n", having been cobbled together from disparate sources. When you're reading text as a series of logical lines, you should always look for all three of the major line-separator styles: Windows ("\r\n"), Unix/Linux/OSX ("\n") and pre-OSX Mac ("\r").

When you're writing text, you should be more concerned with how the file will be used than what platform you're running on. For example, if you expect people to read the file in Windows Notepad, you should use "\r\n" because it only recognizes the one kind of separator.

I actually just ran into this, but for me it was checking for nan, -inf, or inf. I just used

if float('-inf') < float(num) < float('inf'):

This is true for numbers, false for nan and both inf, and will raise an exception for things like strings or other types (which is probably a good thing). Also this does not require importing any libraries like math or numpy (numpy is so damn big it doubles the size of any compiled application).

There are a couple of similar answers up there but my solution with Java seems a little easier to understand. Check this out.

public static int findMinimumNumberOfCoins(int inputCents) {

     // Error Check, If the input is 0 or lower, return 0.
     if(inputCents <= 0) return 0;

     // Create the List of Coins that We need to loop through. Start from highest to lowewst.
     // 25-10-5-1
     int[] mCoinsArray = getCoinsArray();

     // Number of Total Coins.
     int totalNumberOfCoins = 0;

     for(int i=0; i < mCoinsArray.length; i++) {

         // Get the Coin from Array.
         int coin = mCoinsArray[i];

         // If there is no inputCoin Left, simply break the for-loop
         if(inputCents == 0) break;

         // Check If we have a smaller input than our coin
         // If it's, we need to go the Next one in our Coins Array.
         // e.g, if we have 8, but the current index of array is 10, we need to go to 5.
         if(inputCents < coin) continue;

         int quotient = inputCents/coin;
         int remainder = inputCents%coin;

         // Add qutient to number of total coins.
         totalNumberOfCoins += quotient;

         // Update the input with Remainder.
         inputCents = remainder;
     }

     return totalNumberOfCoins;
 }

 // Create a Coins Array, from 25 to 1. Highest is first.
 public static int[] getCoinsArray() {

     int[] mCoinsArray = new int[4];
     mCoinsArray[0] = 25;
     mCoinsArray[1] = 10;
     mCoinsArray[2] = 5;
     mCoinsArray[3] = 1;

     return mCoinsArray;
 }

Download the appropriate APR based tomcat native library for your operating system so that Apache tomcat server can take some advantage of the feature of your OS which is not included by default in tomcat. For windows it will be a .dll file.

I too got the warning while starting the server and you don't have to worry about this if you are testing or developing. This is meant to be on production purposes. After putting the tcnative-1.dll file inside the bin folder of Apache Tomcat 7 following are the output in the stderr file,

I would also highly recomend the AngularJS book from O'Reilly, mentioned by @Atropo.

Something I recently discovered for styling Radio Buttons AND Checkboxes. Before, I had to use jQuery and other things. But this is stupidly simple.

input[type=radio] {
    padding-left:5px;
    padding-right:5px;
    border-radius:15px;

    -webkit-appearance:button;

    border: double 2px #00F;

    background-color:#0b0095;
    color:#FFF;
    white-space: nowrap;
    overflow:hidden;

    width:15px;
    height:15px;
}

input[type=radio]:checked {
    background-color:#000;
    border-left-color:#06F;
    border-right-color:#06F;
}

input[type=radio]:hover {
    box-shadow:0px 0px 10px #1300ff;
}

You can do the same for a checkbox, obviously change the input[type=radio] to input[type=checkbox] and change border-radius:15px; to border-radius:4px;.

Hope this is somewhat useful to you.

If you are using pdo, it will look like

$sql = "UPDATE users SET firstname = :firstname, lastname = :lastname WHERE id= :id";
$query = $this->pdo->prepare($sql);
$result = $query->execute(array(':firstname' => $firstname, ':lastname' => $lastname, ':id' => $id));

Sharing this as I've recently encountered issues similar to this thread

For a long time, my script worked well (basic payment form) and returned the POST variables to my success.php page and the IPN data as POST variables also. However, lately, I noticed the return page (success.php) was no longer receiving any POST vars. I tested in Sandbox and live and I'm pretty sure PayPal have changed something !

The notify_url still receives the correct IPN data allowing me to update DB, but I've not been able to display a success message on my return URL (success.php) page.

Despite trying many combinations to switch options on and off in PayPal website payment preferences and IPN, I've had to make some changes to my script to ensure I can still process a message. I've accomplished this by turning on PDT and Auto Return, after following this excellent guide.

Now it all works fine, but the only issue is the return URL contains all of the PDT variables which is ugly!

assuming input[row][col]

rows = len(input)
cols = len(list(zip(*input)))

Use LEFT combined with CHARINDEX:

UPDATE MyTable
SET MyText = LEFT(MyText, CHARINDEX(';', MyText) - 1)
WHERE CHARINDEX(';', MyText) > 0

Note that the WHERE clause skips updating rows in which there is no semicolon.

Here is some code to verify the SQL above works:

declare @MyTable table ([id] int primary key clustered, MyText varchar(100))
insert into @MyTable ([id], MyText)
select 1, 'some text; some more text'
union all select 2, 'text again; even more text'
union all select 3, 'text without a semicolon'
union all select 4, null -- test NULLs
union all select 5, '' -- test empty string
union all select 6, 'test 3 semicolons; second part; third part;'
union all select 7, ';' -- test semicolon by itself    

UPDATE @MyTable
SET MyText = LEFT(MyText, CHARINDEX(';', MyText) - 1)
WHERE CHARINDEX(';', MyText) > 0

select * from @MyTable

I get the following results:

id MyText
-- -------------------------
1  some text
2  text again
3  text without a semicolon
4  NULL
5        (empty string)
6  test 3 semicolons
7        (empty string)

there is a limited alternative you can use

header:

class std_int_vector;

class A{
    std_int_vector* vector;
public:
    A();
    virtual ~A();
};

cpp:

#include "header.h"
#include <vector>
class std_int_vector: public std::vectror<int> {}

A::A() : vector(new std_int_vector()) {}
[...]

not tested in real programs, so expect it to be non-perfect.

Correct syntax looks like this. See MSDN.

You need to correctly separate static data from instance data. In your code, onLoan and setLoanItem() are instance members. If you want to reference/call them you must do so via an instance. So you either want

public void loanItem() {
    this.media.setLoanItem("Yes");
}

or

public void loanItem(Media object) {
    object.setLoanItem("Yes");
}

depending on how you want to pass that instance around.

Here's my take:

Script:

var originalText = $("#textContainer").html()
$("#search").on('keyup', function () {
  $("#textContainer").html(originalText)
  var text = $("#textContainer").html()
  var val = $("#search").val()
  if(val=="") return;
  var matches = text.split(val)
  for(var i=0;i<matches.length-1;i++) {
    var ind =  matches[i].indexOf(val)
    var len = val.length
      matches[i] = matches[i] + "<span class='selected'>" + val + "</span>"
  }
  $("#textContainer").html(matches.join(""))

HTML:

<input type="text" id="search">
<div id="textContainer">
lorem ipsum is simply dummy text of the printing and typesetting industry. lorem ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of letraset sheets containing lorem ipsum passages, and more recently with desktop publishing software like Aldus pagemaker including versions of lorem ipsum.</div>

First of all, you should be using json.loads, not json.dumps. loads converts JSON source text to a Python value, while dumps goes the other way.

After you fix that, based on the JSON snippet at the top of your question, readable_json will be a list, and so readable_json['firstName'] is meaningless. The correct way to get the 'firstName' field of every element of a list is to eliminate the playerstuff = readable_json['firstName'] line and change for i in playerstuff: to for i in readable_json:.

I wanted to return a string such as "1 day 2 hours 3 minutes" and also take into account if for example days or minuttes are 0 and then not showing them. thanks to John Rasch for his answer which mine is barely an extension of

TimeSpan timeLeft = New Timespan(0, 70, 0);
String.Format("{0}{1}{2}{3}{4}{5}",
    Math.Floor(timeLeft.TotalDays) == 0 ? "" : 
    Math.Floor(timeLeft.TotalDays).ToString() + " ",
    Math.Floor(timeLeft.TotalDays) == 0 ? "" : Math.Floor(timeLeft.TotalDays) == 1 ? "day " : "days ",
    timeLeft.Hours == 0 ? "" : timeLeft.Hours.ToString() + " ",
    timeLeft.Hours == 0 ? "" : timeLeft.Hours == 1 ? "hour " : "hours ",
    timeLeft.Minutes == 0 ? "" : timeLeft.Minutes.ToString() + " ",
    timeLeft.Minutes == 0 ? "" : timeLeft.Minutes == 1 ? "minute " : "minutes ");

By using fabric js we can solve this security error issue in IE.

    function getBase64FromImageUrl(URL) {
        var canvas  = new fabric.Canvas('c');
        var img = new Image();
        img.onload = function() {
            var canvas1 = document.createElement("canvas");
            canvas1.width = this.width;
            canvas1.height = this.height;
            var ctx = canvas.getContext('2d');
            ctx.drawImage(this, 0, 0);
            var dataURL = canvas.toDataURL({format: "png"});
        };
        img.src = URL;
    }

The standard approach is to give the centered element fixed dimensions, and place it absolutely:

<div class='fullscreenDiv'>
    <div class="center">Hello World</div>
</div>?

.center {
    position: absolute;
    width: 100px;
    height: 50px;
    top: 50%;
    left: 50%;
    margin-left: -50px; /* margin is -0.5 * dimension */
    margin-top: -25px; 
}?

• DEMO

Identifiers (including column names) that are not double-quoted are folded to lower case in PostgreSQL. Column names that were created with double-quotes and thereby retained upper-case letters (and/or other syntax violations) have to be double-quoted for the rest of their life:

"first_Name"

Values (string literals / constants) are enclosed in single quotes:

'xyz'

So, yes, PostgreSQL column names are case-sensitive (when double-quoted):

SELECT * FROM persons WHERE "first_Name" = 'xyz';

Read the manual on identifiers here.

My standing advice is to use legal, lower-case names exclusively so double-quoting is not needed.

All the answers above are helpful but none solved my issue. In my production file, my STATIC_URL was https://<URL>/static and I used the same STATIC_URL in my dev settings.py file.

This causes a silent failure in django/conf/urls/static.py.

The test elif not settings.DEBUG or '://' in prefix: picks up the '//' in the URL and does not add the static URL pattern, causing no static files to be found.

It would be thoughtful if Django spit out an error message stating you can't use a http(s):// with DEBUG = True

I had to change STATIC_URL to be '/static/'

You should chain the replace() together instead of assigning the result and replacing again.

var strMessage1 = document.getElementById("element1") ;
strMessage1.innerHTML = strMessage1.innerHTML
                        .replace(/aaaaaa./g,'<a href=\"http://www.google.com/')
                        .replace(/.bbbbbb/g,'/world\">Helloworld</a>');

See DEMO.

Given an object which I suspect to be some kind of IList<>, how can I determine of what it's an IList<>?

Here's the gutsy solution. It assumes you have the actual object to test (rather than a Type).

public static Type ListOfWhat(Object list)
{
    return ListOfWhat2((dynamic)list);
}

private static Type ListOfWhat2<T>(IList<T> list)
{
    return typeof(T);
}

Example usage:

object value = new ObservableCollection<DateTime>();
ListOfWhat(value).Dump();

Prints

typeof(DateTime)

VMware does not allow you to run a 64-bit guest on a 32-bit host. You just have to read the documentation to find this out.

If you really want to do this, you can use QEMU, and I recommend a Linux host, but it's going to be very slow (I really mean slow).

As others have said, @Transient is used to mark fields which shouldn't be persisted. Consider this short example:

public enum Gender { MALE, FEMALE, UNKNOWN }

@Entity
public Person {
    private Gender g;
    private long id;

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    public long getId() { return id; }
    public void setId(long id) { this.id = id; }

    public Gender getGender() { return g; }    
    public void setGender(Gender g) { this.g = g; }

    @Transient
    public boolean isMale() {
        return Gender.MALE.equals(g);
    }

    @Transient
    public boolean isFemale() {
        return Gender.FEMALE.equals(g);
    }
}

When this class is fed to the JPA, it persists the gender and id but doesn't try to persist the helper boolean methods - without @Transient the underlying system would complain that the Entity class Person is missing setMale() and setFemale() methods and thus wouldn't persist Person at all.

Mozilla Developer Network has a nice description and example of onbeforeunload.

If you want to warn the user before leaving the page if your page is dirty (i.e. if user has entered some data):

window.addEventListener('beforeunload', function(e) {
  var myPageIsDirty = ...; //you implement this logic...
  if(myPageIsDirty) {
    //following two lines will cause the browser to ask the user if they
    //want to leave. The text of this dialog is controlled by the browser.
    e.preventDefault(); //per the standard
    e.returnValue = ''; //required for Chrome
  }
  //else: user is allowed to leave without a warning dialog
});

Try this...

if(string1.toLowerCase() == string2.toLowerCase()){
    return true;
}

Also, it's not a loop, it's a block of code. Loops are generally repeated (although they can possibly execute only once), whereas a block of code never repeats.

I read your note about not using toLowerCase, but can't see why it would be a problem.

To add a new file in SVN

svn add file_name
svn commit -m "text about changes..."

To add a new file in a directory in SVN

svn add directory_name/file_name
svn commit -m "text about changes"

To add all new files in a directory with some targets (files) are already versioned (added):

svn add directory_name/*
svn commit -m "text about changes"

I would do using String#tr :

"1,112".tr(',','').to_i # => 1112

Local variables are automatically freed when the function ends, you don't need to free them by yourself. You only free dynamically allocated memory (e.g using malloc) as it's allocated on the heap:

char *arr = malloc(3 * sizeof(char));
strcpy(arr, "bo");
// ...
free(arr);

Summary of all ways to get info on dimensions of DataFrame or Series

There are a number of ways to get information on the attributes of your DataFrame or Series.

Create Sample DataFrame and Series

df = pd.DataFrame({'a':[5, 2, np.nan], 'b':[ 9, 2, 4]})
df

     a  b
0  5.0  9
1  2.0  2
2  NaN  4

s = df['a']
s

0    5.0
1    2.0
2    NaN
Name: a, dtype: float64

shape Attribute

The shape attribute returns a two-item tuple of the number of rows and the number of columns in the DataFrame. For a Series, it returns a one-item tuple.

df.shape
(3, 2)

s.shape
(3,)

len function

To get the number of rows of a DataFrame or get the length of a Series, use the len function. An integer will be returned.

len(df)
3

len(s)
3

size attribute

To get the total number of elements in the DataFrame or Series, use the size attribute. For DataFrames, this is the product of the number of rows and the number of columns. For a Series, this will be equivalent to the len function:

df.size
6

s.size
3

ndim attribute

The ndim attribute returns the number of dimensions of your DataFrame or Series. It will always be 2 for DataFrames and 1 for Series:

df.ndim
2

s.ndim
1

The tricky count method

The count method can be used to return the number of non-missing values for each column/row of the DataFrame. This can be very confusing, because most people normally think of count as just the length of each row, which it is not. When called on a DataFrame, a Series is returned with the column names in the index and the number of non-missing values as the values.

df.count() # by default, get the count of each column

a    2
b    3
dtype: int64


df.count(axis='columns') # change direction to get count of each row

0    2
1    2
2    1
dtype: int64

For a Series, there is only one axis for computation and so it just returns a scalar:

s.count()
2

Use the info method for retrieving metadata

The info method returns the number of non-missing values and data types of each column

df.info()

<class 'pandas.core.frame.DataFrame'>
RangeIndex: 3 entries, 0 to 2
Data columns (total 2 columns):
a    2 non-null float64
b    3 non-null int64
dtypes: float64(1), int64(1)
memory usage: 128.0 bytes

Double them to escape;

SELECT *
  FROM Header
 WHERE userID LIKE '%''%'

The absolute simplest way to accomplish this, is with basename()

echo basename('http://domain.com/artist/song/music-videos/song-title/9393903');

Which will print

9393903

Of course, if there is a query string at the end it will be included in the returned value, in which case the accepted answer is a better solution.

Google has ended support for eclipse plugin. If you prefer to use eclipse still you can download Eclipse Android Development Tool from

You can access Globals entity from any point of your App via Angular dependency injection. If you want to output Globals.role value in some component's template, you should inject Globals through the component's constructor like any service:

// hello.component.ts
import { Component } from '@angular/core';
import { Globals } from './globals';

@Component({
  selector: 'hello',
  template: 'The global role is {{globals.role}}',
  providers: [ Globals ] // this depends on situation, see below
})

export class HelloComponent {
  constructor(public globals: Globals) {}
}

I provided Globals in the HelloComponent, but instead it could be provided in some HelloComponent's parent component or even in AppModule. It will not matter until your Globals has only static data that could not be changed (say, constants only). But if it's not true and for example different components/services might want to change that data, then the Globals must be a singleton. In that case it should be provided in the topmost level of the hierarchy where it is going to be used. Let's say this is AppModule:

import { Globals } from './globals'

@NgModule({
  // ... imports, declarations etc
  providers: [
    // ... other global providers
    Globals // so do not provide it into another components/services if you want it to be a singleton
  ]
})

Also, it's impossible to use var the way you did, it should be

// globals.ts
import { Injectable } from '@angular/core';

@Injectable()
export class Globals {
  role: string = 'test';
}

Update

At last, I created a simple demo on stackblitz, where single Globals is being shared between 3 components and one of them can change the value of Globals.role.

In modern browsers that support HTML5, the following is possible:

<a href="link/to/your/download/file" download>Download link</a>

You also can use this:

<a href="link/to/your/download/file" download="filename">Download link</a>

This will allow you to change the name of the file actually being downloaded.

Try with this code -
It is a totally dynamic solution:

    var form = $(document.createElement('form'));
    $(form).attr("action", "reserves.php");
    $(form).attr("method", "POST");

    var input = $("<input>").attr("type", "hidden").attr("name", "mydata").val("bla");
    $(form).append($(input));
    $(form).submit();

I'm a beginner in Android, but got it working like this:

in AndroidManifest.xml, make sure you, inside <application>, have something like this:

<service android:name="com.some.package.name.YourServiceSubClassName" android:permission="com.some.package.name.YourServiceSubClassName">
    <intent-filter>
        <action android:name="com.some.package.name.YourServiceSubClassName"/>
    </intent-filter>
</service>

where YourServiceSubClassName extend android.app.Service is your java class that is the service. Where com.some.package is the package name, for me both in AndroidManifest.xml and in Java. Used a javabeat.net article as help, look for <service>

Note also, supposedly between the package name and the class name there should be .service. in the text, I guess this is some convention, but for me this caused ClassNotFoundException that I'm yet to solve.

Then, install your apk. I did from eclipse but also adb install -r yourApkHere.apk should work. Uninstall is adb uninstall com.some.package.name, btw.

You can start it from host system like this, thanks Just a Tim and MrRoy:

adb shell am startservice com.some.package.name/.YourServiceSubClassName

interestingly, I didn't need -n.

To stop, I use

adb shell am force-stop com.some.package.name

Hope it helps.

As I'm a beginner, please feel freet to edit/comment to fix any misconceptions (eg. probably regarding .service. in the component (?) name).

You can use these string functions,

strstr — Find the first occurrence of a string

stristr — Case-insensitive strstr()

strrchr — Find the last occurrence of a character in a string

strpos — Find the position of the first occurrence of a substring in a string

strpbrk — Search a string for any of a set of characters

If that doesn't help then you should use preg regular expression

preg_match — Perform a regular expression match

Based on this answer, I did this in my React component:

export default React.memo(() => {
    const containerRef = React.useRef(null);

    React.useEffect(() => {
        document.addEventListener('mousedown', handleMouseMove);

        return () => document.removeEventListener('mousedown', handleMouseMove);
    }, []);

    const handleMouseMove = React.useCallback(() => {
        const drag = (e) => {
            console.log('mouse is moving');
        };

        const lift = (e) => {
            console.log('mouse move ended');
            window.removeEventListener('mousemove', drag);
            window.removeEventListener('mouseup', this);
        };

        window.addEventListener('mousemove', drag);
        window.addEventListener('mouseup', lift);
    }, []);

    return (
        <div style={{ width: '100vw', height: '100vh' }} ref={containerRef} />
    );
})

I think there is some confusion about the difference between MVC and Web Api. In short, for MVC you can use a login form and create a session using cookies. For Web Api there is no session. That's why you want to use the token.

You do not need a login form. The Token endpoint is all you need. Like Win described you'll send the credentials to the token endpoint where it is handled.

Here's some client side C# code to get a token:

    //using System;
    //using System.Collections.Generic;
    //using System.Net;
    //using System.Net.Http;
    //string token = GetToken("https://localhost:<port>/", userName, password);

    static string GetToken(string url, string userName, string password) {
        var pairs = new List<KeyValuePair<string, string>>
                    {
                        new KeyValuePair<string, string>( "grant_type", "password" ), 
                        new KeyValuePair<string, string>( "username", userName ), 
                        new KeyValuePair<string, string> ( "Password", password )
                    };
        var content = new FormUrlEncodedContent(pairs);
        ServicePointManager.ServerCertificateValidationCallback += (sender, cert, chain, sslPolicyErrors) => true;
        using (var client = new HttpClient()) {
            var response = client.PostAsync(url + "Token", content).Result;
            return response.Content.ReadAsStringAsync().Result;
        }
    }

In order to use the token add it to the header of the request:

    //using System;
    //using System.Collections.Generic;
    //using System.Net;
    //using System.Net.Http;
    //var result = CallApi("https://localhost:<port>/something", token);

    static string CallApi(string url, string token) {
        ServicePointManager.ServerCertificateValidationCallback += (sender, cert, chain, sslPolicyErrors) => true;
        using (var client = new HttpClient()) {
            if (!string.IsNullOrWhiteSpace(token)) {
                var t = JsonConvert.DeserializeObject<Token>(token);

                client.DefaultRequestHeaders.Clear();
                client.DefaultRequestHeaders.Add("Authorization", "Bearer " + t.access_token);
            }
            var response = client.GetAsync(url).Result;
            return response.Content.ReadAsStringAsync().Result;
        }
    }

Where Token is:

//using Newtonsoft.Json;

class Token
{
    public string access_token { get; set; }
    public string token_type { get; set; }
    public int expires_in { get; set; }
    public string userName { get; set; }
    [JsonProperty(".issued")]
    public string issued { get; set; }
    [JsonProperty(".expires")]
    public string expires { get; set; }
}

Now for the server side:

In Startup.Auth.cs

        var oAuthOptions = new OAuthAuthorizationServerOptions
        {
            TokenEndpointPath = new PathString("/Token"),
            Provider = new ApplicationOAuthProvider("self"),
            AccessTokenExpireTimeSpan = TimeSpan.FromDays(14),
            // https
            AllowInsecureHttp = false
        };
        // Enable the application to use bearer tokens to authenticate users
        app.UseOAuthBearerTokens(oAuthOptions);

And in ApplicationOAuthProvider.cs the code that actually grants or denies access:

//using Microsoft.AspNet.Identity.Owin;
//using Microsoft.Owin.Security;
//using Microsoft.Owin.Security.OAuth;
//using System;
//using System.Collections.Generic;
//using System.Security.Claims;
//using System.Threading.Tasks;

public class ApplicationOAuthProvider : OAuthAuthorizationServerProvider
{
    private readonly string _publicClientId;

    public ApplicationOAuthProvider(string publicClientId)
    {
        if (publicClientId == null)
            throw new ArgumentNullException("publicClientId");

        _publicClientId = publicClientId;
    }

    public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
    {
        var userManager = context.OwinContext.GetUserManager<ApplicationUserManager>();

        var user = await userManager.FindAsync(context.UserName, context.Password);
        if (user == null)
        {
            context.SetError("invalid_grant", "The user name or password is incorrect.");
            return;
        }

        ClaimsIdentity oAuthIdentity = await user.GenerateUserIdentityAsync(userManager);
        var propertyDictionary = new Dictionary<string, string> { { "userName", user.UserName } };
        var properties = new AuthenticationProperties(propertyDictionary);

        AuthenticationTicket ticket = new AuthenticationTicket(oAuthIdentity, properties);
        // Token is validated.
        context.Validated(ticket);
    }

    public override Task TokenEndpoint(OAuthTokenEndpointContext context)
    {
        foreach (KeyValuePair<string, string> property in context.Properties.Dictionary)
        {
            context.AdditionalResponseParameters.Add(property.Key, property.Value);
        }
        return Task.FromResult<object>(null);
    }

    public override Task ValidateClientAuthentication(OAuthValidateClientAuthenticationContext context)
    {
        // Resource owner password credentials does not provide a client ID.
        if (context.ClientId == null)
            context.Validated();

        return Task.FromResult<object>(null);
    }

    public override Task ValidateClientRedirectUri(OAuthValidateClientRedirectUriContext context)
    {
        if (context.ClientId == _publicClientId)
        {
            var expectedRootUri = new Uri(context.Request.Uri, "/");

            if (expectedRootUri.AbsoluteUri == context.RedirectUri)
                context.Validated();
        }
        return Task.FromResult<object>(null);
    }

}

As you can see there is no controller involved in retrieving the token. In fact, you can remove all MVC references if you want a Web Api only. I have simplified the server side code to make it more readable. You can add code to upgrade the security.

Make sure you use SSL only. Implement the RequireHttpsAttribute to force this.

You can use the Authorize / AllowAnonymous attributes to secure your Web Api. Additionally you can add filters (like RequireHttpsAttribute) to make your Web Api more secure. I hope this helps.

File -> Source Control -> Advanced -> Change Source Control and then unbind and/or disconnect all projects and the solution.

This should remove all bindings from the solution and project files. (After this you can switch the SCC provider in Tools -> Options -> Source Control -> Plug-in Selection).

The SCC specification prescribes that all SCC providers should implement this behavior. (I only tested it for VSS, TFS and AnkhSVN)

It works fine for me: http://jsfiddle.net/qwertynl/htb9h/

My javascript:

var app = angular.module("myApp", [])
app.controller("MyCtrl", ['$scope', function($scope) {
    $scope.telephone = []; // << remember to set this
}]);

I solved it by renaming my function.

Changed

function editForm(value)

to

function editTheForm(value)

Works perfectly.

Stored procedures are a batch of SQL statements that can be executed in a couple of ways. Most major DBMs support stored procedures; however, not all do. You will need to verify with your particular DBMS help documentation for specifics. As I am most familiar with SQL Server I will use that as my samples.

To create a stored procedure the syntax is fairly simple:

CREATE PROCEDURE <owner>.<procedure name>

     <Param> <datatype>

AS

     <Body>

So for example:

CREATE PROCEDURE Users_GetUserInfo

    @login nvarchar(30)=null

AS

    SELECT * from [Users]
    WHERE ISNULL(@login,login)=login

A benefit of stored procedures is that you can centralize data access logic into a single place that is then easy for DBA's to optimize. Stored procedures also have a security benefit in that you can grant execute rights to a stored procedure but the user will not need to have read/write permissions on the underlying tables. This is a good first step against SQL injection.

Stored procedures do come with downsides, basically the maintenance associated with your basic CRUD operation. Let's say for each table you have an Insert, Update, Delete and at least one select based on the primary key, that means each table will have 4 procedures. Now take a decent size database of 400 tables, and you have 1600 procedures! And that's assuming you don't have duplicates which you probably will.

This is where using an ORM or some other method to auto generate your basic CRUD operations has a ton of merit.

Here is another way of doing it.

class Parameter(models.Model):

    def __init__(self, *args, **kwargs):
        super(Parameter, self).__init__(*args, **kwargs)
        self.__original_value = self.value

    def clean(self,*args,**kwargs):
        if self.__original_value == self.value:
            print("igual")
        else:
            print("distinto")

    def save(self,*args,**kwargs):
        self.full_clean()
        return super(Parameter, self).save(*args, **kwargs)
        self.__original_value = self.value

    key = models.CharField(max_length=24, db_index=True, unique=True)
    value = models.CharField(max_length=128)

As per documentation: validating objects

"The second step full_clean() performs is to call Model.clean(). This method should be overridden to perform custom validation on your model. This method should be used to provide custom model validation, and to modify attributes on your model if desired. For instance, you could use it to automatically provide a value for a field, or to do validation that requires access to more than a single field:"

Given the security concerns about using the PGPASSWORD environment variable, I think the best overall solution is as follows:

1. Write your own temporary pgpass file with the password you want to use.
2. Use the PGPASSFILE environment variable to tell psql to use that file.
3. Remove the temporary pgpass file

There are a couple points of note here. Step 1 is there to avoid mucking with the user's ~/.pgpass file that might exist. You also must make sure that the file has permissions 0600 or less.

Some have suggested leveraging bash to shortcut this as follows:

PGPASSFILE=<(echo myserver:5432:mydb:jdoe:password) psql -h myserver -U jdoe -p 5432 mydb

This uses the <() syntax to avoid needing to write the data to an actual file. But it doesn't work because psql checks what file is being used and will throw an error like this:

WARNING: password file "/dev/fd/63" is not a plain file

You can check for type of a variable using __name__ of a type.

Ex:

>>> a = [1,2,3,4]  
>>> b = 1  
>>> type(a).__name__
'list'
>>> type(a).__name__ == 'list'
True
>>> type(b).__name__ == 'list'
False
>>> type(b).__name__
'int'

Think I have the answer, distilled from the above and a little experimentation.

progressBar.Value = progressBar.Maximum - 1;
progressBar.Maximum = progressBar.Value;

I tried decrementing the value and the screen updated even in debug mode, but that would not work for setting progressBar.Value to progressBar.Maximum, because you cannot set the progress bar value above the maximum, so I first set the progressBar.Value to progressBar.Maximum -1, then set progressBar.Maxiumum to equal progressBar.Value. They say there is more than one way of killing a cat. Sometimes I'd like to kill Bill Gates or whoever it is now :o).

With this result, I did not even appear to need to Invalidate(), Refresh(), Update(), or do anything to the progress bar or its Panel container or the parent Form.

@mikemaccana answer is useful.

And I also used https://github.com/ryanseddon/H5F. Found on http://microjs.com. It's some kind of polyfill and you can use it as follows (jQuery is used in example):

if ( $('form')[0].checkValidity() ) {
    // the form is valid
}

Technically possible. You would probably reference employees_ce in deductions and employees_sn. But why don't you merge employees_sn and employees_ce? I see no reason why you have two table. No one to many relationship. And (not in this example) many columns.

If you do two references for one column, an employee must have an entry in both tables.

For the problem you're having about the batch file asking the user if the destination is a folder or file, if you know the answer in advance, you can do as such:

If destination is a file: echo f | [batch file path]

If folder: echo d | [batch file path]

It will essentially just pipe the letter after "echo" to the input of the batch file.

Use the find command.

Assuming you're using Bash 4.2+, use -printf '%T+ %p\n' for file timestamp value.

find $DIR -type f -printf '%T+ %p\n' | sort -r | head -n 1 | cut -d' ' -f2

Example:

find ~/Downloads -type f -printf '%T+ %p\n' | sort -r | head -n 1 | cut -d' ' -f2

For a more useful script, see the find-latest script here: https://github.com/l3x/helpers

If you have a string line, you can use the .encode([encoding], [errors='strict']) method for strings to convert encoding types.

line = 'my big string'

line.encode('ascii', 'ignore')

For more information about handling ASCII and unicode in Python, this is a really useful site: https://docs.python.org/2/howto/unicode.html

Advantages:

Note: I intend to keep this answer up to date with the latest specs of Bootstrap 3. For a Bootstrap 4 solution, see this answer (for now they are more or less the same, but in time they might diverge). If you find any bug or problem with it, let me know and I will update. Thanks.

Clean, un-prefixed SCSS (for use with gulp/grunt):

.modal-dialog {
  display: flex;
  flex-direction: column;
  justify-content: center;
  overflow-y: auto;
  min-height: calc(100vh - 60px);
  @media (max-width: 767px) {
    min-height: calc(100vh - 20px);
  }
}

You can use Reflection to obtain the actual names of the properties.

http://www.csharp-examples.net/reflection-property-names/

If you need a way to assign a "String Name" to a property, why don't you write an attribute that you can reflect over to get the string name?

[StringName("MyStringName")]
private string MyProperty
{
    get { ... }
}

import pandas as pd 
import os 
files = os.listdir('path/to/files/directory/')
desiredFile = files[i]
filePath = 'path/to/files/directory/%s'
Ofile = filePath % desiredFile
xls_import = pd.read_csv(Ofile)

Now you can use the power of pandas DataFrames!

I also like to build locators from up to bottom like:

//div[contains(@class,'btn-group')][./button[contains(.,'Arcade Reader')]]/button[@name='settings']

It's pretty simple, as we just search btn-group with button[contains(.,'Arcade Reader')] and get it's button[@name='settings']

That's just another option to build xPath locators

What is the profit of searching wrapper element: you can return it by method (example in java) and just build selenium constructions like:

getGroupByName("Arcade Reader").find("button[name='settings']");
getGroupByName("Arcade Reader").find("button[name='delete']");

or even simplify more

getGroupButton("Arcade Reader", "delete").click();

If you want to remain both filename (only) and extension, you may use %~nxF:

FOR /R C:\Directory %F in (*.*) do echo %~nxF

Thanks to duncan answer, I end up with this:

marker.addListener('mouseover', () => infoWindow.open(map, marker))
marker.addListener('mouseout', () => infoWindow.close())

You should be aware that you should avoid file I/O from within Linux kernel when possible. The main idea is to go "one level deeper" and call VFS level functions instead of the syscall handler directly:

Includes:

#include <linux/fs.h>
#include <asm/segment.h>
#include <asm/uaccess.h>
#include <linux/buffer_head.h>

Opening a file (similar to open):

struct file *file_open(const char *path, int flags, int rights) 
{
    struct file *filp = NULL;
    mm_segment_t oldfs;
    int err = 0;

    oldfs = get_fs();
    set_fs(get_ds());
    filp = filp_open(path, flags, rights);
    set_fs(oldfs);
    if (IS_ERR(filp)) {
        err = PTR_ERR(filp);
        return NULL;
    }
    return filp;
}

Close a file (similar to close):

void file_close(struct file *file) 
{
    filp_close(file, NULL);
}

Reading data from a file (similar to pread):

int file_read(struct file *file, unsigned long long offset, unsigned char *data, unsigned int size) 
{
    mm_segment_t oldfs;
    int ret;

    oldfs = get_fs();
    set_fs(get_ds());

    ret = vfs_read(file, data, size, &offset);

    set_fs(oldfs);
    return ret;
}   

Writing data to a file (similar to pwrite):

int file_write(struct file *file, unsigned long long offset, unsigned char *data, unsigned int size) 
{
    mm_segment_t oldfs;
    int ret;

    oldfs = get_fs();
    set_fs(get_ds());

    ret = vfs_write(file, data, size, &offset);

    set_fs(oldfs);
    return ret;
}

Syncing changes a file (similar to fsync):

int file_sync(struct file *file) 
{
    vfs_fsync(file, 0);
    return 0;
}

[Edit] Originally, I proposed using file_fsync, which is gone in newer kernel versions. Thanks to the poor guy suggesting the change, but whose change was rejected. The edit was rejected before I could review it.

Set a local and environment variable using Bash on Linux

Check for a local or environment variables for a variable called LOL in Bash:

el@server /home/el $ set | grep LOL
el@server /home/el $
el@server /home/el $ env | grep LOL
el@server /home/el $

Sanity check, no local or environment variable called LOL.

Set a local variable called LOL in local, but not environment. So set it:

el@server /home/el $ LOL="so wow much code"
el@server /home/el $ set | grep LOL
LOL='so wow much code'
el@server /home/el $ env | grep LOL
el@server /home/el $

Variable 'LOL' exists in local variables, but not environment variables. LOL will disappear if you restart the terminal, logout/login or run exec bash.

Set a local variable, and then clear out all local variables in Bash

el@server /home/el $ LOL="so wow much code"
el@server /home/el $ set | grep LOL
LOL='so wow much code'
el@server /home/el $ exec bash
el@server /home/el $ set | grep LOL
el@server /home/el $

You could also just unset the one variable:

el@server /home/el $ LOL="so wow much code"
el@server /home/el $ set | grep LOL
LOL='so wow much code'
el@server /home/el $ unset LOL
el@server /home/el $ set | grep LOL
el@server /home/el $

Local variable LOL is gone.

Promote a local variable to an environment variable:

el@server /home/el $ DOGE="such variable"
el@server /home/el $ export DOGE
el@server /home/el $ set | grep DOGE
DOGE='such variable'
el@server /home/el $ env | grep DOGE
DOGE=such variable

Note that exporting makes it show up as both a local variable and an environment variable.

Exported variable DOGE above survives a Bash reset:

el@server /home/el $ exec bash
el@server /home/el $ env | grep DOGE
DOGE=such variable
el@server /home/el $ set | grep DOGE
DOGE='such variable'

Unset all environment variables:

You have to pull out a can of Chuck Norris to reset all environment variables without a logout/login:

el@server /home/el $ export CAN="chuck norris"
el@server /home/el $ env | grep CAN
CAN=chuck norris
el@server /home/el $ set | grep CAN
CAN='chuck norris'
el@server /home/el $ env -i bash
el@server /home/el $ set | grep CAN
el@server /home/el $ env | grep CAN

You created an environment variable, and then reset the terminal to get rid of them.

Or you could set and unset an environment variable manually like this:

el@server /home/el $ export FOO="bar"
el@server /home/el $ env | grep FOO
FOO=bar
el@server /home/el $ unset FOO
el@server /home/el $ env | grep FOO
el@server /home/el $

Note: this answer is only valid for git v1.8 and older.

Most of this has been said in the other answers and comments, but here's a concise explanation:

• git fetch fetches all branch heads (or all specified by the remote.fetch config option), all commits necessary for them, and all tags which are reachable from these branches. In most cases, all tags are reachable in this way.
• git fetch --tags fetches all tags, all commits necessary for them. It will not update branch heads, even if they are reachable from the tags which were fetched.

Summary: If you really want to be totally up to date, using only fetch, you must do both.

It's also not "twice as slow" unless you mean in terms of typing on the command-line, in which case aliases solve your problem. There is essentially no overhead in making the two requests, since they are asking for different information.

To answer your first question: yes it is feasible to develop an android application in pure python, in order to achieve this I suggest you use BeeWare, which is just a suite of python tools, that work together very well and they enable you to develop platform native applications in python.

checkout this video by the creator of BeeWare that perfectly explains and demonstrates it's application

How it works

Android's preferred language of implementation is Java - so if you want to write an Android application in Python, you need to have a way to run your Python code on a Java Virtual Machine. This is what VOC does. VOC is a transpiler - it takes Python source code, compiles it to CPython Bytecode, and then transpiles that bytecode into Java-compatible bytecode. The end result is that your Python source code files are compiled directly to a Java .class file, which can be packaged into an Android application.

VOC also allows you to access native Java objects as if they were Python objects, implement Java interfaces with Python classes, and subclass Java classes with Python classes. Using this, you can write an Android application directly against the native Android APIs.

Once you've written your native Android application, you can use Briefcase to package your Python code as an Android application.

Briefcase is a tool for converting a Python project into a standalone native application. You can package projects for:

• Mac
• Windows
• Linux
• iPhone/iPad
• Android
• AppleTV
• tvOS.

You can check This native Android Tic Tac Toe app written in Python, using the BeeWare suite. on GitHub

in addition to the BeeWare tools, you'll need to have a JDK and Android SDK installed to test run your application.

and to answer your second question: a good environment can be anything you are comfortable with be it a text editor and a command line, or an IDE, if you're looking for a good python IDE I would suggest you try Pycharm, it has a community edition which is free, and it has a similar environment as android studio, due to to the fact that were made by the same company.

I hope this has been helpful

DELETE FROM blob
WHERE NOT EXISTS (
    SELECT *
    FROM files
    WHERE id=blob.id
)

Personally I would go with:

DataTable tbl = Gridview1.DataSource as DataTable;

This would allow you to test for null as this results in either DataTable object or null. Casting it as a DataTable using (DataTable)Gridview1.DataSource would cause a crashing error in case the DataSource is actually a DataSet or even some kind of collection.

Supporting Documentation: MSDN Documentation on "as"

You can use .change() function too

E.g.:

$('form input[type=checkbox]').change(function() { console.log('hello') });

You just need to iterate the anchors in the two links.

<a href="#hide2" class="hide" id="hide2">+</a>
<a href="#show2" class="show" id="show2">-</a>

See this jsfiddle http://jsfiddle.net/eJX8z/

I also added some margin to the FAQ call to improve the format.

Since "zebra" is a remote branch, I was thinking I don't have its data locally.

You are correct that you don't have the right data, but tried to resolve it in the wrong way. To collect data locally from a remote source, you need to use git fetch. When you did git checkout zebra you switched to whatever the state of that branch was the last time you fetched. So fetch from the remote first:

# fetch just the one remote
git fetch <remote>
# or fetch from all remotes
git fetch --all
# make sure you're back on the branch you want to cherry-pick to
git cherry-pick xyz

Both ItemListener as well as ActionListener, in case of JCheckBox have the same behaviour. However, major difference is ItemListener can be triggered by calling the setSelected(true) on the checkbox. As a coding practice do not register both ItemListener as well as ActionListener with the JCheckBox, in order to avoid inconsistency.

-X [your method]
X lets you override the default 'Get'

** corrected lowercase x to uppercase X

Use the :disabled CSS3 pseudo-selector

function add(){
    var first=parseFloat($("#first").val());
    var second=parseFloat($("#second").val());
    $("#result").val(+(first+second).toFixed(2));
}

DEMO.

I made a wider input field by using either span4 or span6 as class.

<input type="text" class="span6 input-large search-query">

This way you don't need the additional custom css, mentioned earlier.

You can see a difference between the two contexts when you launch your app directly from the home screen vs when your app is launched from another app via share intent.

Here a practical example of what "non-standard back stack behaviors", mentioned by @CommonSenseCode, means:

Suppose that you have two apps that communicate with each other, App1 and App2.

Launch App2:MainActivity from launcher. Then from MainActivity launch App2:SecondaryActivity. There, either using activity context or application context, both activities live in the same task and this is ok (given that you use all standard launch modes and intent flags). You can go back to MainActivity with a back press and in the recent apps you have only one task.

Suppose now that you are in App1 and launch App2:MainActivity with a share intent (ACTION_SEND or ACTION_SEND_MULTIPLE). Then from there try to launch App2:SecondaryActivity (always with all standard launch modes and intent flags). What happens is:

• if you launch App2:SecondaryActivity with application context on Android < 10 you cannot launch all the activities in the same task. I have tried with android 7 and 8 and the SecondaryActivity is always launched in a new task (I guess is because App2:SecondaryActivity is launched with the App2 application context but you're coming from App1 and you didn't launch the App2 application directly. Maybe under the hood android recognize that and use FLAG_ACTIVITY_NEW_TASK). This can be good or bad depending on your needs, for my application was bad.
  On Android 10 the app crashes with the message
  "Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want?".
  So to make it work on Android 10 you have to use FALG_ACTIVITY_NEW_TASK and you cannot run all activities in the same task.
  As you can see the behavior is different between android versions, weird.

• if you launch App2:SecondaryActivity with activity context all goes well and you can run all the activities in the same task resulting in a linear backstack navigation.

I hope I have added some useful information

Using GitPython will give you a good python interface to Git.

For example, after installing it (pip install gitpython), for cloning a new repository you can use clone_from function:

from git import Repo

Repo.clone_from(git_url, repo_dir)

See the GitPython Tutorial for examples on using the Repo object.

Note: GitPython requires git being installed on the system, and accessible via system's PATH.

You should explore SQL Server\Memory Manager performance counters.

pandas.io.sql.frame_query is deprecated. Use pandas.read_sql instead.

If Khanh TO's solution caused UI issues for you (like it did for me) try using $timeout to not update the attribute until it has been unchanged for 500ms.

var oldWidth = window.innerWidth;
$(window).on('resize.doResize', function () {
    var newWidth = window.innerWidth,
        updateStuffTimer;

    if (newWidth !== oldWidth) {
        $timeout.cancel(updateStuffTimer);
    }

    updateStuffTimer = $timeout(function() {
         updateStuff(newWidth); // Update the attribute based on window.innerWidth
    }, 500);
});

$scope.$on('$destroy',function (){
    $(window).off('resize.doResize'); // remove the handler added earlier
});

Reference: https://gist.github.com/tommaitland/7579618

Check the current value of your "readonly" attribute, if it's "false" (a string) or empty (undefined or "") then it's not readonly.

$('input').each(function() {
    var readonly = $(this).attr("readonly");
    if(readonly && readonly.toLowerCase()!=='false') { // this is readonly
        alert('this is a read only field');
    }
});

Best settings for Sublime Text 3 as your Git editor (Windows & Linux instructions):

To follow these instructions in Windows make sure you have installed Git for Windows. In Windows, I like to use Git Bash so that it feels more like Linux.

First, we want to create a special Sublime Text project so that we can specify special project settings we want set whenever Git calls the editor, to make things easier when editing in Git. For example, I normally set my ruler to 120 chars in most projects, but for Git commit messages I want it to be 72 characters so that it fits nicely in a terminal when you call git log or git lg.

1. Create a Sublime Text project with settings we want to use to edit Git commit messages

Open Sublime Text and go to menu "File" ? "New Window" to create a new anonymous project. Go to menu "Project" ? "Save Project As..." and choose a place to save it. In Linux I saved it in my Linux home directory with the file name .gitconfig.sublime-project. Its path is therefore: ~/.gitconfig.sublime-project. In Windows also save it in your home directory, for example: C:\Users\MY_USER_NAME\.gitconfig.sublime-project Now go to menu "Project" ? "Edit Project" to edit the project settings. Paste the following and save the settings. Make any further edits for your project settings if desired.

{
    // For folder settings help see here: https://www.sublimetext.com/docs/3/projects.html

    "folders":
    [

    ],

    "settings":
    {

        // Disables horizontal scrolling if enabled.
        // May be set to true, false, or "auto", where it will be disabled for
        // source code, and otherwise enabled.
        "word_wrap": false,

        // Set to a value other than 0 to force wrapping at that column rather than the
        // window width
        "wrap_width": 0,

        // Columns in which to display vertical rulers
        "rulers": [72, 50], //72 is recommended by git for commit message content, and 50 for commit titles

        // The number of spaces a tab is considered equal to
        "tab_size": 4,

        // Set to true to insert spaces when tab is pressed
        "translate_tabs_to_spaces": true,
    },

    "build_systems":
    [

    ]

}

2. Set the editor to be used by Git

Now we need to set the editor to be used by Git, by editing the .gitconfig file.

For Linux:

Your user copy of this will be located in ~/.gitconfig. Open this file and add the following lines. Be sure to use the proper path name to the Git project you just created above! I'm using ~/.gitconfig.sublime-project.

[core]
    editor = subl --project ~/.gitconfig.sublime-project --wait

The --wait is important, as it forces Git to wait until you close the file before it continues on. The --project line is important to tell Sublime Text which project you want opened whenever Git opens Sublime Text.

Per @digitaldreamer's answer above (https://stackoverflow.com/a/2596835/4561887), "subl can be replaced by the full path of the executable but [the alias subl] is usually available when [Sublime is] correctly installed."

For Windows:

For Windows, first read the Linux instructions for background information. Now we will do something almost identical.

(OPTIONAL: create a subl alias for use in Git Bash):

Open up a text editor (for example, Notepad, Notepad++, Sublime Text, Geany, etc.), and create a file called ".bash_profile" in your home directory. Its path will therefore be: C:\Users\MY_USER_NAME\.bash_profile. Save the following into it:

alias subl="/c/Program\ Files/Sublime\ Text\ 3/subl.exe"

This creates a Git Bash alias called subl that we can now use in Git Bash for Windows, to easily open Sublime Text. This step isn't required, but it's useful for general Git Bash use. Now you can call subl ., for instance, in Git Bash to open up a new Sublime Text project in your current directory.

(MANDATORY):

Edit the .gitconfig file found in your home directory: C:\Users\MY_USER_NAME\.gitconfig, by adding the following to it. Notice the subtle changes from the Linux instructions above:

[core]
  editor = 'C:/Program Files/Sublime Text 3/subl.exe' --project ~/.gitconfig.sublime-project --wait

• Notice that you must specify the full path to the Sublime Text executable. Note the direction of the slashes! Use / NOT \ to separate folders in the path name! (Thanks VonC for helping me see this).
• Our subl alias we made for Git Bash above doesn't work here, so you can't use it like we did in the Linux example, instead you must specify the whole path as shown above.
• The ~ symbol, however, does still work here to get to your Windows home directory.

2.5. (Optional) Install the "Git" package into Sublime Text 3.

This gives you syntax highlighting for git commit messages, as well as access to other Git commands such as git blame (which I use frequently in Sublime Text) or git commit (which I don't use in Sublime Text since I'd prefer the command-line for general Git flow, as I've mentioned in my comments below this answer).

To install a package: First, ensure “Package Control” is installed. Next, press Ctrl + Shift + P (same as Tools ? Command Palette) and type all or part of “Package Control: Install Package”, then press Enter. In the search box that comes up, search for the package "Git" and hit Enter on it, or click on it, to automatically install it.

Once installed, Ctrl + Shift + P then searching for "git" will bring up Git commands you can use internally inside Sublime Text now, such as git blame.

3. Use it

Now when you call git commit, for instance, as normal from the command-line, Sublime Text will open up into the .gitconfig.sublime-project we created above, with that project's settings! As you type a paragraph you'll notice it extends past the ruler we set since soft word-wrap is off. To force hard wrap via auto-inserted hard-returns at the end of each line, put your cursor on the long line you want auto-wrapped and press Alt + Q. It will now hard-wrap/hard-fold at 72 characters, which is what we set in the project settings' "rulers" parameter above.

Now, save your commit message with Ctrl + S, and exit (to complete your git commit) with Ctrl + Shift + W.

Done!

As pointed out by others, increasing the limit is not the best answer. I was facing the same issue, but in my code I was nowhere using any event listener. When I closely looked into the code, I was creating a lot of promises at times. Each promise had some code of scraping the provided URL (using some third-party library). If you are doing something like that, then it may be the cause.

Refer this thread on how to prevent that: What is the best way to limit concurrency when using ES6's Promise.all()?

The problem in this case is that onchange-event does not fire until the input looses focus, so you will probably want to listen for the keyup-event instead, which is fired on every keystroke.

Also, I would prefer not using inline-javascript, but rather catch the event using jQuery instead.

$("#txtConfirmPassword").keyup(checkPasswordMatch);

I want to return odd numbers of an array

If i read that correctly, you want something like this?

List<Integer> getOddNumbers(int[] integers) {
  List<Integer> oddNumbers = new ArrayList<Integer>();
  for (int i : integers)
    if (i % 2 != 0)
      oddNumbers.add(i);
  return oddNumbers;
}

http://us2.php.net/date

echo date('Y');

Please do not use NSDate, CFAbsoluteTimeGetCurrent, or gettimeofday to measure elapsed time. These all depend on the system clock, which can change at any time due to many different reasons, such as network time sync (NTP) updating the clock (happens often to adjust for drift), DST adjustments, leap seconds, and so on.

This means that if you're measuring your download or upload speed, you will get sudden spikes or drops in your numbers that don't correlate with what actually happened; your performance tests will have weird incorrect outliers; and your manual timers will trigger after incorrect durations. Time might even go backwards, and you end up with negative deltas, and you can end up with infinite recursion or dead code (yeah, I've done both of these).

Use mach_absolute_time. It measures real seconds since the kernel was booted. It is monotonically increasing (will never go backwards), and is unaffected by date and time settings. Since it's a pain to work with, here's a simple wrapper that gives you NSTimeIntervals:

// LBClock.h
@interface LBClock : NSObject
+ (instancetype)sharedClock;
// since device boot or something. Monotonically increasing, unaffected by date and time settings
- (NSTimeInterval)absoluteTime;

- (NSTimeInterval)machAbsoluteToTimeInterval:(uint64_t)machAbsolute;
@end

// LBClock.m
#include <mach/mach.h>
#include <mach/mach_time.h>

@implementation LBClock
{
    mach_timebase_info_data_t _clock_timebase;
}

+ (instancetype)sharedClock
{
    static LBClock *g;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        g = [LBClock new];
    });
    return g;
}

- (id)init
{
    if(!(self = [super init]))
        return nil;
    mach_timebase_info(&_clock_timebase);
    return self;
}

- (NSTimeInterval)machAbsoluteToTimeInterval:(uint64_t)machAbsolute
{
    uint64_t nanos = (machAbsolute * _clock_timebase.numer) / _clock_timebase.denom;

    return nanos/1.0e9;
}

- (NSTimeInterval)absoluteTime
{
    uint64_t machtime = mach_absolute_time();
    return [self machAbsoluteToTimeInterval:machtime];
}
@end

Just use for x in f: ..., this gives you line after line, is much shorter and readable (partly because it automatically stops when the file ends) and also saves you the rstrip call because the trailing newline is already stipped.

The error is caused by the exit condition, which can never be true: Even if the file is exhausted, readline will return an empty string, not None. Also note that you could still run into trouble with empty lines, e.g. at the end of the file. Adding if line.strip() == "": continue makes the code ignore blank lines, which is propably a good thing anyway.

Note many third-party clients have own timezone settings overlapping any Postgres server and\or session settings.

E.g. if you're using 'IntelliJ IDEA 2017.3' (or DataGrips), you should define timezone as:

'DB source properties' -> 'Advanced' tab -> 'VM Options': -Duser.timezone=UTC+06:00

otherwise you will see 'UTC' despite of whatever you have set anywhere else.

.env files are hidden by Netbeans. To show them do this:

Tools > Options > Miscellaneous > Files

Under Files Ignored be the IDE is Ignored Files Pattern:

The default is

^(CVS|SCCS|vssver.?\.scc|#.*#|%.*%|_svn)$|~$|^\.(?!(htaccess|git.+|hgignore)$).*$

Add env to the excluded-not-excluded bit

^(CVS|SCCS|vssver.?\.scc|#.*#|%.*%|_svn)$|~$|^\.(?!(env|htaccess|git.+|hgignore)$).*$

Files named .env now show.

If you want the latest file in the directory and you are using only the LastWriteTime to determine the latest file, you can do something like below:

gci path | sort LastWriteTime | select -last 1

On the other hand, if you want to only rely on the names that have the dates in them, you should be able to something similar

gci path | select -last 1

Also, if there are directories in the directory, you might want to add a ?{-not $_.PsIsContainer}

        catch (Exception) {  }
        return;
    }

A query string carries textual data so there is no option but to explode the array, encode it correctly and pass it in a representational format of your choice:

p1=value1&pN=valueN...
data=[value1,...,valueN]
data={p1:value1,...,pN:valueN}

and then decode it in your server side code.

Given that the only logical difference between the handlers is the value of the button clicked, you can use the this keyword to refer to the element which raised the event and get the val() from that. Try this:

$("button").click(function(e) {
    e.preventDefault();
    $.ajax({
        type: "POST",
        url: "/pages/test/",
        data: { 
            id: $(this).val(), // < note use of 'this' here
            access_token: $("#access_token").val() 
        },
        success: function(result) {
            alert('ok');
        },
        error: function(result) {
            alert('error');
        }
    });
});

mylist = [("aaaa8"),("bb8"),("ccc8"),("dddddd8")]
print mylist
j=0
for i in mylist:
    mylist[j]=i.rstrip("8")
    j+=1
print mylist

Or if You are little less on the evangelist's side You can do a little ugly way I'm using. In deploy_template there are commits I want to copy on my master as branch deploy

git branch deploy deploy_template
git checkout deploy
git rebase master

This will create new branch deploy (I use -f to overwrite existing deploy branch) on deploy_template, then rebase this new branch onto master, leaving deploy_template untouched.

The .c is the source file and .h is the header file.

Though this question is rather old and has already been answered, I just want to add a note on how to do proper exception handling in C++11:

Use std::nested_exception and std::throw_with_nested

It is described on StackOverflow here and here, how you can get a backtrace on your exceptions inside your code without need for a debugger or cumbersome logging, by simply writing a proper exception handler which will rethrow nested exceptions.

Since you can do this with any derived exception class, you can add a lot of information to such a backtrace! You may also take a look at my MWE on GitHub, where a backtrace would look something like this:

Library API: Exception caught in function 'api_function'
Backtrace:
~/Git/mwe-cpp-exception/src/detail/Library.cpp:17 : library_function failed
~/Git/mwe-cpp-exception/src/detail/Library.cpp:13 : could not open file "nonexistent.txt"

I prefix this reply with "you shouldn't use a regular expression to parse XML -- it's only going to result in edge cases that don't work right, and a forever-increasing-in-complexity regex while you try to fix it."

That being said, you need to proceed by matching the string and grabbing the group you want:

if (m.matches())
{
   String result = m.group(1);
   // do something with result
}

The accepted answer currently fires twice for animations in Chrome. Presumably this is because it recognizes webkitAnimationEnd as well as animationEnd. The following will definitely only fires once:

/* From Modernizr */
function whichTransitionEvent(){

    var el = document.createElement('fakeelement');
    var transitions = {
        'animation':'animationend',
        'OAnimation':'oAnimationEnd',
        'MSAnimation':'MSAnimationEnd',
        'WebkitAnimation':'webkitAnimationEnd'
    };

    for(var t in transitions){
        if( transitions.hasOwnProperty(t) && el.style[t] !== undefined ){
            return transitions[t];
        }
    }
}

$("#elementToListenTo")
    .on(whichTransitionEvent(),
        function(e){
            console.log('Transition complete!  This is the callback!');
            $(this).off(e);
        });

?? The accepted solution is outdated.

Here are two scenarios where the keyup event will not get fired:

1. The user drags text into the textarea.
2. The user copy-paste text in the textarea with a right click (contextual menu).

Use the HTML5 input event instead for a more robust solution:

<textarea maxlength='140'></textarea>

JavaScript (demo):

const textarea = document.querySelector("textarea");

textarea.addEventListener("input", event => {
    const target = event.currentTarget;
    const maxLength = target.getAttribute("maxlength");
    const currentLength = target.value.length;

    if (currentLength >= maxLength) {
        return console.log("You have reached the maximum number of characters.");
    }

    console.log(`${maxLength - currentLength} chars left`);
});

And if you absolutely want to use jQuery:

$('textarea').on("input", function(){
    var maxlength = $(this).attr("maxlength");
    var currentLength = $(this).val().length;

    if( currentLength >= maxlength ){
        console.log("You have reached the maximum number of characters.");
    }else{
        console.log(maxlength - currentLength + " chars left");
    }
});

The normal name resolution in Python works fine. Why do you need DNSpython for that. Just use socket's getaddrinfo which follows the rules configured for your operating system (on Debian, it follows /etc/nsswitch.conf:

>>> print socket.getaddrinfo('google.com', 80)
[(10, 1, 6, '', ('2a00:1450:8006::63', 80, 0, 0)), (10, 2, 17, '', ('2a00:1450:8006::63', 80, 0, 0)), (10, 3, 0, '', ('2a00:1450:8006::63', 80, 0, 0)), (10, 1, 6, '', ('2a00:1450:8006::68', 80, 0, 0)), (10, 2, 17, '', ('2a00:1450:8006::68', 80, 0, 0)), (10, 3, 0, '', ('2a00:1450:8006::68', 80, 0, 0)), (10, 1, 6, '', ('2a00:1450:8006::93', 80, 0, 0)), (10, 2, 17, '', ('2a00:1450:8006::93', 80, 0, 0)), (10, 3, 0, '', ('2a00:1450:8006::93', 80, 0, 0)), (2, 1, 6, '', ('209.85.229.104', 80)), (2, 2, 17, '', ('209.85.229.104', 80)), (2, 3, 0, '', ('209.85.229.104', 80)), (2, 1, 6, '', ('209.85.229.99', 80)), (2, 2, 17, '', ('209.85.229.99', 80)), (2, 3, 0, '', ('209.85.229.99', 80)), (2, 1, 6, '', ('209.85.229.147', 80)), (2, 2, 17, '', ('209.85.229.147', 80)), (2, 3, 0, '', ('209.85.229.147', 80))]

There's a third way that doesn't require a converter or a change to your view model: use a style:

<Style TargetType="Button">
   <Setter Property="Visibility" Value="Collapsed"/>
   <Style.Triggers>
      <DataTrigger Binding="{Binding IsVisible}" Value="True">
         <Setter Property="Visibility" Value="Visible"/>
      </DataTrigger>
   </Style.Triggers>
</Style>

I tend to prefer this technique because I use it in a lot of cases where what I'm binding to is not boolean - e.g. displaying an element only if its DataContext is not null, or implementing multi-state displays where different layouts appear based on the setting of an enum in the view model.

In order to use nslookup, host or gethostbyname() then the target's name will need to be registered with DNS or statically defined in the hosts file on the machine running your program. Yes, you could connect to the target with SSH or some other application and query it directly, but for a generic solution you'll need some sort of DNS entry for it.

@Ahamed has a point, but if you're insisting on using lists so you can have three arraylist like this:

ArrayList<Integer> first = new ArrayList<Integer>(Arrays.AsList(100,100,100,100,100));
ArrayList<Integer> second = new ArrayList<Integer>(Arrays.AsList(50,35,25,45,65));
ArrayList<Integer> third = new ArrayList<Integer>();

for(int i = 0; i < first.size(); i++) {
      third.add(first.get(i));
      third.add(second.get(i));
}

Edit: If you have those values on your list that below:

List<double[]> values = new ArrayList<double[]>(2);

what you want to do is combine them, right? You can try something like this: (I assume that both array are same sized, otherwise you need to use two for statement)

ArrayList<Double> yourArray = new ArrayList<Double>();
for(int i = 0; i < values.get(0).length; i++) {
    yourArray.add(values.get(0)[i]);
    yourArray.add(values.get(1)[i]);
}

Let's make a Go 1-compatible list of all the ways to read and write files in Go.

Because file API has changed recently and most other answers don't work with Go 1. They also miss bufio which is important IMHO.

In the following examples I copy a file by reading from it and writing to the destination file.

Start with the basics

package main

import (
    "io"
    "os"
)

func main() {
    // open input file
    fi, err := os.Open("input.txt")
    if err != nil {
        panic(err)
    }
    // close fi on exit and check for its returned error
    defer func() {
        if err := fi.Close(); err != nil {
            panic(err)
        }
    }()

    // open output file
    fo, err := os.Create("output.txt")
    if err != nil {
        panic(err)
    }
    // close fo on exit and check for its returned error
    defer func() {
        if err := fo.Close(); err != nil {
            panic(err)
        }
    }()

    // make a buffer to keep chunks that are read
    buf := make([]byte, 1024)
    for {
        // read a chunk
        n, err := fi.Read(buf)
        if err != nil && err != io.EOF {
            panic(err)
        }
        if n == 0 {
            break
        }

        // write a chunk
        if _, err := fo.Write(buf[:n]); err != nil {
            panic(err)
        }
    }
}

Here I used os.Open and os.Create which are convenient wrappers around os.OpenFile. We usually don't need to call OpenFile directly.

Notice treating EOF. Read tries to fill buf on each call, and returns io.EOF as error if it reaches end of file in doing so. In this case buf will still hold data. Consequent calls to Read returns zero as the number of bytes read and same io.EOF as error. Any other error will lead to a panic.

Using bufio

package main

import (
    "bufio"
    "io"
    "os"
)

func main() {
    // open input file
    fi, err := os.Open("input.txt")
    if err != nil {
        panic(err)
    }
    // close fi on exit and check for its returned error
    defer func() {
        if err := fi.Close(); err != nil {
            panic(err)
        }
    }()
    // make a read buffer
    r := bufio.NewReader(fi)

    // open output file
    fo, err := os.Create("output.txt")
    if err != nil {
        panic(err)
    }
    // close fo on exit and check for its returned error
    defer func() {
        if err := fo.Close(); err != nil {
            panic(err)
        }
    }()
    // make a write buffer
    w := bufio.NewWriter(fo)

    // make a buffer to keep chunks that are read
    buf := make([]byte, 1024)
    for {
        // read a chunk
        n, err := r.Read(buf)
        if err != nil && err != io.EOF {
            panic(err)
        }
        if n == 0 {
            break
        }

        // write a chunk
        if _, err := w.Write(buf[:n]); err != nil {
            panic(err)
        }
    }

    if err = w.Flush(); err != nil {
        panic(err)
    }
}

bufio is just acting as a buffer here, because we don't have much to do with data. In most other situations (specially with text files) bufio is very useful by giving us a nice API for reading and writing easily and flexibly, while it handles buffering behind the scenes.

Note: The following code is for older Go versions (Go 1.15 and before). Things have changed. For the new way, take a look at this answer.

Using ioutil

package main

import (
    "io/ioutil"
)

func main() {
    // read the whole file at once
    b, err := ioutil.ReadFile("input.txt")
    if err != nil {
        panic(err)
    }

    // write the whole body at once
    err = ioutil.WriteFile("output.txt", b, 0644)
    if err != nil {
        panic(err)
    }
}

Easy as pie! But use it only if you're sure you're not dealing with big files.

Use mouseover instead hover.

$('#target').on('click mouseover', function () {
    // Do something for both
});

You can do the following:

Load the data:

test <- read.csv(
          "http://archive.ics.uci.edu/ml/machine-learning-databases/breast-cancer-wisconsin/breast-cancer-wisconsin.data",
          header=FALSE)

Note that the default value of the header argument for read.csv is TRUE so in order to get all lines you need to set it to FALSE.

Add names to the different columns in the data.frame

names(test) <- c("A","B","C","D","E","F","G","H","I","J","K")

or alternative and faster as I understand (not reloading the entire dataset):

colnames(test) <- c("A","B","C","D","E","F","G","H","I","J","K")

Here is another good explanation from the book:

As for the difference between SCOPE_IDENTITY and @@IDENTITY, suppose that you have a stored procedure P1 with three statements:
- An INSERT that generates a new identity value
- A call to a stored procedure P2 that also has an INSERT statement that generates a new identity value
- A statement that queries the functions SCOPE_IDENTITY and @@IDENTITY The SCOPE_IDENTITY function will return the value generated by P1 (same session and scope). The @@IDENTITY function will return the value generated by P2 (same session irrespective of scope).

You should not play with the height. Let the text field determine the height based on the font used.

If you want to control the width of the text field then you can use

textField.setColumns(...);

to let the text field determine the preferred width.

Or if you want the width to be the entire width of the parent panel then you need to use an appropriate layout. Maybe the NORTH of a BorderLayout.

See the Swing tutorial on Layout Managers for more information.

I had the same problem under Windows and could solve it by running cmd.exe as administrator (right-click in start menu, then "Run as administrator).

i have tried this article Code Project, it is working fine for me. I have used the code too. article is excellent in explanation with screenshot.

I am adding necessary explanation to this scenario

You have just booted up your computer and are about to log on. When you log on, the system assigns you a unique Session ID. In Windows Vista, the first User to log on to the computer is assigned a Session ID of 1 by the OS. The next User to log on will be assigned a Session ID of 2. And so on and so forth. You can view the Session ID assigned to each logged on User from the Users tab in Task Manager.

But your windows service is brought under session ID of 0. This session is isolated from other sessions. This ultimately prevent the windows service to invoke the application running under user session's like 1 or 2.

In order to invoke the application from windows service you need to copy the control from winlogon.exe which acts as present logged user as shown in below screenshot.

Important codes

// obtain the process id of the winlogon process that 
// is running within the currently active session
Process[] processes = Process.GetProcessesByName("winlogon");
foreach (Process p in processes)
{
    if ((uint)p.SessionId == dwSessionId)
    {
        winlogonPid = (uint)p.Id;
    }
}

// obtain a handle to the winlogon process
hProcess = OpenProcess(MAXIMUM_ALLOWED, false, winlogonPid);

// obtain a handle to the access token of the winlogon process
if (!OpenProcessToken(hProcess, TOKEN_DUPLICATE, ref hPToken))
{
    CloseHandle(hProcess);
    return false;
}

// Security attibute structure used in DuplicateTokenEx and   CreateProcessAsUser
// I would prefer to not have to use a security attribute variable and to just 
// simply pass null and inherit (by default) the security attributes
// of the existing token. However, in C# structures are value types and   therefore
// cannot be assigned the null value.
SECURITY_ATTRIBUTES sa = new SECURITY_ATTRIBUTES();
sa.Length = Marshal.SizeOf(sa);

// copy the access token of the winlogon process; 
// the newly created token will be a primary token
if (!DuplicateTokenEx(hPToken, MAXIMUM_ALLOWED, ref sa, 
    (int)SECURITY_IMPERSONATION_LEVEL.SecurityIdentification, 
    (int)TOKEN_TYPE.TokenPrimary, ref hUserTokenDup))
    {
      CloseHandle(hProcess);
      CloseHandle(hPToken);
      return false;
    }

 STARTUPINFO si = new STARTUPINFO();
 si.cb = (int)Marshal.SizeOf(si);

// interactive window station parameter; basically this indicates 
// that the process created can display a GUI on the desktop
si.lpDesktop = @"winsta0\default";

// flags that specify the priority and creation method of the process
int dwCreationFlags = NORMAL_PRIORITY_CLASS | CREATE_NEW_CONSOLE;

// create a new process in the current User's logon session
 bool result = CreateProcessAsUser(hUserTokenDup,  // client's access token
                            null,             // file to execute
                            applicationName,  // command line
                            ref sa,           // pointer to process    SECURITY_ATTRIBUTES
                            ref sa,           // pointer to thread SECURITY_ATTRIBUTES
                            false,            // handles are not inheritable
                            dwCreationFlags,  // creation flags
                            IntPtr.Zero,      // pointer to new environment block 
                            null,             // name of current directory 
                            ref si,           // pointer to STARTUPINFO structure
                            out procInfo      // receives information about new process
                            );

I was struggling with Outlook and Office365. Surprisingly the thing that seemed to work was:

<table align='center' style='text-align:center'>
  <tr>
    <td align='center' style='text-align:center'>
      <!-- AMAZING CONTENT! -->
    </td>
  </tr>
</table>

I only listed some of the key things that resolved my Microsoft email issues.

Might I add that building an email that looks nice on all emails is a pain. This website was super nice for testing: https://putsmail.com/

It allows you to list all the emails you'd like to send your test email to. You can paste your code right into the window, edit, send, and resend. It helped me a ton.

    for using this, you can create a Repository for example this one:
    Member findByEmail(String email);

    List<Member> findByDate(Date date);
    // custom query example and return a member
   @Query("select m from Member m where m.username = :username and m.password=:password")
        Member findByUsernameAndPassword(@Param("username") String username, @Param("password") String password);

I had the same question, so I created Git Merger.
hope this helps :)

Here is a solution that also makes it easy to show a loading view in the end of the ListView while it's loading.

You can see the classes here:

https://github.com/CyberEagle/OpenProjects/blob/master/android-projects/widgets/src/main/java/br/com/cybereagle/androidwidgets/helper/ListViewWithLoadingIndicatorHelper.java - Helper to make it possible to use the features without extending from SimpleListViewWithLoadingIndicator.

https://github.com/CyberEagle/OpenProjects/blob/master/android-projects/widgets/src/main/java/br/com/cybereagle/androidwidgets/listener/EndlessScrollListener.java - Listener that starts loading data when the user is about to reach the bottom of the ListView.

https://github.com/CyberEagle/OpenProjects/blob/master/android-projects/widgets/src/main/java/br/com/cybereagle/androidwidgets/view/SimpleListViewWithLoadingIndicator.java - The EndlessListView. You can use this class directly or extend from it.

Segments of p

Assume p contains all possible finite number combinations. See math.stackexchange question

1. Determine the number of digits needed from the size of the array.
2. Use segments of p places as indexes to determine how to re-order the array. If a segment exceeds the size boundaries for this array, adjust the p decimal offset and start over.
3. Check if the re-ordered array is sorted. If it is woot, else adjust the offset and start over.

Multiple box shadows did it for me.

box-shadow:
        inset 0 -8px 4px 4px rgb(255,255,255),
        inset 0 2px 4px 0px rgba(50, 50, 50, 0.75);

Without Mutate

Actually, all unshift/push and shift/pop mutate the origin array.

The unshift/push add an item to the existed array from begin/end and shift/pop remove an item from the beginning/end of an array.

But there are few ways to add items to an array without a mutation. the result is a new array, to add to the end of array use below code:

const originArray = ['one', 'two', 'three'];
const newItem = 4;

const newArray = originArray.concat(newItem); // ES5
const newArray2 = [...originArray, newItem]; // ES6+

To add to begin of original array use below code:

const originArray = ['one', 'two', 'three'];
const newItem = 0;

const newArray = (originArray.slice().reverse().concat(newItem)).reverse(); // ES5
const newArray2 = [newItem, ...originArray]; // ES6+

With the above way, you add to the beginning/end of an array without a mutation.

Those error messages

CMake Error at ... (project):
    No CMAKE_C_COMPILER could be found.
-- Configuring incomplete, errors occurred!
See also ".../CMakeFiles/CMakeOutput.log".
See also ".../CMakeFiles/CMakeError.log".

or

CMake Error: your CXX compiler: "CMAKE_CXX_COMPILER-NOTFOUND" was not found.
Please set CMAKE_CXX_COMPILER to a valid compiler path or name.
...
-- Configuring incomplete, errors occurred!

just mean that CMake was unable to find your C/CXX compiler to compile a simple test program (one of the first things CMake tries while detecting your build environment).

The steps to find your problem are dependent on the build environment you want to generate. The following tutorials are a collection of answers here on Stack Overflow and some of my own experiences with CMake on Microsoft Windows 7/8/10 and Ubuntu 14.04.

Preconditions

• You have installed the compiler/IDE and it was able to once compile any other program (directly without CMake)
  • You e.g. may have the IDE, but may not have installed the compiler or supporting framework itself like described in Problems generating solution for VS 2017 with CMake or How do I tell CMake to use Clang on Windows?
• You have the latest CMake version
• You have access rights on the drive you want CMake to generate your build environment

• You have a clean build directory (because CMake does cache things from the last try) e.g. as sub-directory of your source tree

  Windows cmd.exe

  > rmdir /s /q VS2015
  > mkdir VS2015
  > cd VS2015
  

  Bash shell

  $ rm -rf MSYS
  $ mkdir MSYS
  $ cd MSYS
  

  and make sure your command shell points to your newly created binary output directory.

General things you can/should try

1. Is CMake able find and run with any/your default compiler? Run without giving a generator

   > cmake ..
   -- Building for: Visual Studio 14 2015
   ...
   

   Perfect if it correctly determined the generator to use - like here Visual Studio 14 2015

2. What was it that actually failed?

   In the previous build output directory look at CMakeFiles\CMakeError.log for any error message that make sense to you or try to open/compile the test project generated at CMakeFiles\[Version]\CompilerIdC|CompilerIdCXX directly from the command line (as found in the error log).

CMake can't find Visual Studio

1. Try to select the correct generator version:

   > cmake --help
   > cmake -G "Visual Studio 14 2015" ..
   

2. If that doesn't help, try to set the Visual Studio environment variables first (the path could vary):

   > "c:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat"
   > cmake ..
   

   or use the Developer Command Prompt for VS2015 short-cut in your Windows Start Menu under All Programs/Visual Studio 2015/Visual Studio Tools (thanks at @Antwane for the hint).

Background: CMake does support all Visual Studio releases and flavors (Express, Community, Professional, Premium, Test, Team, Enterprise, Ultimate, etc.). To determine the location of the compiler it uses a combination of searching the registry (e.g. at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\[Version];InstallDir), system environment variables and - if none of the others did come up with something - plainly try to call the compiler.

CMake can't find GCC (MinGW/MSys)

1. You start the MSys bash shell with msys.bat and just try to directly call gcc

   $ gcc
   gcc.exe: fatal error: no input files
   compilation terminated.
   

   Here it did find gcc and is complaining that I didn't gave it any parameters to work with.

   So the following should work:

   $ cmake -G "MSYS Makefiles" ..
   -- The CXX compiler identification is GNU 4.8.1
   ...
   $ make
   

   If GCC was not found call export PATH=... to add your compilers path (see How to set PATH environment variable in CMake script?) and try again.

2. If it's still not working, try to set the CXX compiler path directly by exporting it (path may vary)

   $ export CC=/c/MinGW/bin/gcc.exe
   $ export CXX=/c/MinGW/bin/g++.exe
   $ cmake -G "MinGW Makefiles" ..
   -- The CXX compiler identification is GNU 4.8.1
   ...
   $ mingw32-make
   

   For more details see How to specify new GCC path for CMake

   Note: When using the "MinGW Makefiles" generator you have to use the mingw32-make program distributed with MinGW

3. Still not working? That's weird. Please make sure that the compiler is there and it has executable rights (see also preconditions chapter above).

   Otherwise the last resort of CMake is to not try any compiler search itself and set CMake's internal variables directly by

   $ cmake -DCMAKE_C_COMPILER=/c/MinGW/bin/gcc.exe -DCMAKE_CXX_COMPILER=/c/MinGW/bin/g++.exe ..
   

   For more details see Cmake doesn't honour -D CMAKE_CXX_COMPILER=g++ and Cmake error setting compiler

   Alternatively those variables can also be set via cmake-gui.exe on Windows. See Cmake cannot find compiler

Background: Much the same as with Visual Studio. CMake supports all sorts of GCC flavors. It searches the environment variables (CC, CXX, etc.) or simply tries to call the compiler. In addition it will detect any prefixes (when cross-compiling) and tries to add it to all binutils of the GNU compiler toolchain (ar, ranlib, strip, ld, nm, objdump, and objcopy).

Can also be done like this:-

package main
import "fmt"     

func main(){
    var myname string
fmt.Scanf("%s", &myname)           
fmt.Println("Hello", myname)       
}

You will find the right icon to click, when you open a file or the welcome page, in the upper right corner.

And you can add a keyboard shortcut:

Write out a table starting with 0.

{0,1,2,3,4}

Continue the table in rows.

{0,1,2,3,4}
{5,6,7,8,9}
{10,11,12,13,14}

Everything in column one is a multiple of 5. Everything in column 2 is a multiple of 5 with 1 as a remainder. Now the abstract part: You can write that (1) as 1/5 or as a decimal expansion. The modulus operator returns only the column, or in another way of thinking, it returns the remainder on long division. You are dealing in modulo(5). Different modulus, different table. Think of a Hash Table.

+1 for print_r(). Use it to dump out the contents of an object or variable. To make it more readable, do it with a pre tag so you don't need to view source.

echo '<pre>';
print_r($arrayOrObject);

Also var_dump($thing) - this is very useful to see the type of subthings

you'll probably want to look into jquery-ui dialog. it's highly customizable and can be made to work exactly like lightbox/fancybox and supports everything you would need for a contact form from a regular link.

there is even an example with a form.

hi just to add another way: from this page : https://docs.microsoft.com/it-it/dotnet/api/system.linq.enumerable.range?view=netcore-3.1

you can use this form If you want to Generates a sequence of integral numbers within a specified range strat 0 to 9:

using System.Linq
.....
public int[] arrayName = Enumerable.Range(0, 9).ToArray();

I cobbled together this solution by scouring the Internet including

• Stack Overflow answers,
• MSDN articles,
• http://css-tricks.com/almanac/properties/t/transform/,
• http://caniuse.com/#search=transform,
• http://browserhacks.com/, and
• http://www.useragentman.com/IETransformsTranslator/.

This solution seems to work in all browsers including IE6+, using scale(-1,1) (a proper mirror) and appropriate filter/-ms-filter properties when necessary (IE6-8):

/* Cross-browser mirroring of content. Note that CSS pre-processors
  like Less cough on the media hack. 

  Microsoft recommends using BasicImage as a more efficent/faster form of
  mirroring, instead of FlipH or some kind of Matrix scaling/transform.
  @see http://msdn.microsoft.com/en-us/library/ms532972%28v=vs.85%29.aspx
  @see http://msdn.microsoft.com/en-us/library/ms532992%28v=vs.85%29.aspx
*/

/* IE8 only via hack: necessary because IE9+ will also interpret -ms-filter,
  and mirroring something that's already mirrored results in no net change! */
@media \0screen {
  .mirror {
    -ms-filter: "progid:DXImageTransform.Microsoft.BasicImage(mirror=1)";
  }
}
.mirror {
  /* IE6 and 7 via hack */
  *filter: progid:DXImageTransform.Microsoft.BasicImage(mirror=1);
  /* Standards browsers, including IE9+ */
  -moz-transform: scale(-1,1);
  -ms-transform: scale(-1,1);
  -o-transform: scale(-1,1); /* Op 11.5 only */
  -webkit-transform: scale(-1,1);
  transform: scale(-1,1);
}

For enter event handling you can use

1. @keyup.enter or
2. @keyup.13

13 is the keycode of enter. For @ key event, the keycode is 50. So you can use @keyup.50.

For example:

<input @keyup.50="atPress()" />

Laravel 5 gets its enviroment related variables from the .env file located in the root of your project. You just need to set APP_ENV to whatever you want, for example:

APP_ENV=development

This is used to identify the current enviroment. If you want to display errors, you'll need to enable debug mode in the same file:

APP_DEBUG=true

The role of the .env file is to allow you to have different settings depending on which machine you are running your application. So on your production server, the .env file settings would be different from your local development enviroment.

\n dosen't work. Use html tags

document.write("<br>");
document.write("?");

This will work for me:

.../xampp/htdocs/php/test.phtml

To simplify things here's a jQuery plugin that can achieve this goal : https://github.com/haggen/readonly

1. Include readonly.js in your project. (also needs jquery)

2. Replace .attr('readonly', 'readonly') with .readonly() instead. That's it.

   For example, change from $(".someClass").attr('readonly', 'readonly'); to $(".someClass").readonly();.

you can wrap reserved words in square brackets to avoid these kinds of errors:

dbo.TableName.[Date]

The way to determine the coordinates depends on what element you're working with. For circles for example, the cx and cy attributes determine the center position. In addition, you may have a translation applied through the transform attribute which changes the reference point of any coordinates.

Most of the ways used in general to get screen coordinates won't work for SVGs. In addition, you may not want absolute coordinates if the line you want to draw is in the same container as the elements it connects.

Edit:

In your particular code, it's quite difficult to get the position of the node because its determined by a translation of the parent element. So you need to get the transform attribute of the parent node and extract the translation from that.

d3.transform(d3.select(this.parentNode).attr("transform")).translate

Working jsfiddle here.

you can try

position: relative;
bottom: 20px;

but I don't see a problem on my browser (Google Chrome)

1. In your nginx.conf file, add mime.types to your http body like so:

   http {
       include /etc/nginx/mime.types;
       include /etc/nginx/conf.d/*.conf;
   }
   

2. Now go to the terminal and run the following to reload the server:

   sudo nginx -s reload
   

3. Open your web browser and do a hard reload: Right click on the reload button and select hard reload. On Chrome you can do Ctrl+Shift+R

require(TSDT)

c(1,3,11) %nin% 1:10
# [1] FALSE FALSE  TRUE

In your User model, add the following line in the User class:

public $timestamps = true;

Now, whenever you save or update a user, Laravel will automatically update the created_at and updated_at fields.

Update:
If you want to set the created at manually you should use the date format Y-m-d H:i:s. The problem is that the format you have used is not the same as Laravel uses for the created_at field.

Update: Nov 2018 Laravel 5.6 "message": "Access level to App\\Note::$timestamps must be public", Make sure you have the proper access level as well. Laravel 5.6 is public.

Simple way is to convert into column

SELECT COLUMN_VALUE FROM TABLE (SPLIT ('19869,19572,19223,18898,10155,'))

CREATE TYPE split_tbl as TABLE OF VARCHAR2(32767);

CREATE OR REPLACE FUNCTION split (p_list VARCHAR2, p_del VARCHAR2 := ',')
   RETURN split_tbl
   PIPELINED IS
   l_idx PLS_INTEGER;
   l_list VARCHAR2 (32767) := p_list;
   l_value VARCHAR2 (32767);
BEGIN
   LOOP
      l_idx := INSTR (l_list, p_del);

      IF l_idx > 0 THEN
         PIPE ROW (SUBSTR (l_list, 1, l_idx - 1));
         l_list := SUBSTR (l_list, l_idx + LENGTH (p_del));
      ELSE
         PIPE ROW (l_list);
         EXIT;
      END IF;
   END LOOP;

   RETURN;
END split;

The family of methods that does this are:

• int indexOf(String str)
  • indexOf(String str, int fromIndex)
• int lastIndexOf(String str)
  • lastIndexOf(String str, int fromIndex)

Returns the index within this string of the first (or last) occurrence of the specified substring [searching forward (or backward) starting at the specified index].

String text = "0123hello9012hello8901hello7890";
String word = "hello";

System.out.println(text.indexOf(word)); // prints "4"
System.out.println(text.lastIndexOf(word)); // prints "22"

// find all occurrences forward
for (int i = -1; (i = text.indexOf(word, i + 1)) != -1; i++) {
    System.out.println(i);
} // prints "4", "13", "22"

// find all occurrences backward
for (int i = text.length(); (i = text.lastIndexOf(word, i - 1)) != -1; i++) {
    System.out.println(i);
} // prints "22", "13", "4"

This is partially pseudocode, but you will want something like:

rows = ActiveSheet.UsedRange.Rows
n = 0

while n <= rows
  if ActiveSheet.Rows(n).Cells(DateColumnOrdinal).Value > '8/1/08' AND < '8/30/08' then
     ActiveSheet.Rows(n).CopyTo(DestinationSheet)
  endif
  n = n + 1
