I created a service that will do this for you.

Pass in a standard $http object, and add some extra parameters.

1) A "type" parameter. Specifying the type of file you're retrieving. Defaults to: 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'
2) A "fileName" parameter. This is required, and should include the extension.

Example:

httpDownloader({
  method : 'POST',
  url : '--- enter the url that returns a file here ---',
  data : ifYouHaveDataEnterItHere,
  type : 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet', // this is the default
  fileName : 'YourFileName.xlsx'
}).then(res => {}).catch(e => {});

That's all you need. The file will be downloaded to the user's device without a popup.

Here's the git repo: https://github.com/stephengardner/ngHttpDownloader

To set headers in an Axios POST request, pass the third object to the axios.post() call.

const token = '..your token..'

axios.post(url, {
  //...data
}, {
  headers: {
    'Authorization': `Basic ${token}` 
  }
})

To set headers in an Axios GET request, pass a second object to the axios.get() call.

const token = '..your token..' 

axios.get(url, {
  headers: {
    'Authorization': `Basic ${token}`
  }
})

Cheers!! Read Simple Write Simple

@DougW has clearly answered this question, but I still like to add some codes here to explain Doug's points. (And correct errors in the code above)

Solution 1: URL-encode the POST data with a content-type header :application/x-www-form-urlencoded .

Note: you do not need to urlencode $_POST[] fields one by one, http_build_query() function can do the urlencoding job nicely.

$fields = array(
    'mediaupload'=>$file_field,
    'username'=>$_POST["username"],
    'password'=>$_POST["password"],
    'latitude'=>$_POST["latitude"],
    'longitude'=>$_POST["longitude"],
    'datetime'=>$_POST["datetime"],
    'category'=>$_POST["category"],
    'metacategory'=>$_POST["metacategory"],
    'caption'=>$_POST["description"]
);

$fields_string = http_build_query($fields);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS,$fields_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);

Solution 2: Pass the array directly as the post data without URL-encoding, while the Content-Type header will be set to multipart/form-data.

$fields = array(
        'mediaupload'=>$file_field,
        'username'=>$_POST["username"],
        'password'=>$_POST["password"],
        'latitude'=>$_POST["latitude"],
        'longitude'=>$_POST["longitude"],
        'datetime'=>$_POST["datetime"],
        'category'=>$_POST["category"],
        'metacategory'=>$_POST["metacategory"],
        'caption'=>$_POST["description"]
    );

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL,$url);
    curl_setopt($ch, CURLOPT_POST,1);
    curl_setopt($ch, CURLOPT_POSTFIELDS,$fields);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $response = curl_exec($ch);

Both code snippets work, but using different HTTP headers and bodies.

Just Use

import  qs from "qs";
 let data = {
        'profileId': this.props.screenProps[0],
        'accountId': this.props.screenProps[1],
        'accessToken': this.props.screenProps[2],
        'itemId': this.itemId
    };
    return axios.post(METHOD_WALL_GET, qs.stringify(data))

Here's an example previously found at androidsnippets.com (the site is currently not maintained anymore).

// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://www.yoursite.com/script.php");

try {
    // Add your data
    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
    nameValuePairs.add(new BasicNameValuePair("id", "12345"));
    nameValuePairs.add(new BasicNameValuePair("stringdata", "AndDev is Cool!"));
    httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

    // Execute HTTP Post Request
    HttpResponse response = httpclient.execute(httppost);

} catch (ClientProtocolException e) {
    // TODO Auto-generated catch block
} catch (IOException e) {
    // TODO Auto-generated catch block
}

So, you can add your parameters as BasicNameValuePair.

An alternative is to use (Http)URLConnection. See also Using java.net.URLConnection to fire and handle HTTP requests. This is actually the preferred method in newer Android versions (Gingerbread+). See also this blog, this developer doc and Android's HttpURLConnection javadoc.

Try echo_read_request_body.

"echo_read_request_body ... Explicitly reads request body so that the $request_body variable will always have non-empty values (unless the body is so big that it has been saved by Nginx to a local temporary file)."

location /log {
  log_format postdata $request_body;
  access_log /mnt/logs/nginx/my_tracking.access.log postdata;
  echo_read_request_body;
}

Symfony doc to get request data

Finally, the raw data sent with the request body can be accessed using getContent():

$content = $request->getContent();

Looks like you're already using request module.

in this case all you need to post multipart/form-data is to use its form feature:

var req = request.post(url, function (err, resp, body) {
  if (err) {
    console.log('Error!');
  } else {
    console.log('URL: ' + body);
  }
});
var form = req.form();
form.append('file', '<FILE_DATA>', {
  filename: 'myfile.txt',
  contentType: 'text/plain'
});

but if you want to post some existing file from your file system, then you may simply pass it as a readable stream:

form.append('file', fs.createReadStream(filepath));

request will extract all related metadata by itself.

For more information on posting multipart/form-data see node-form-data module, which is internally used by request.

An alternative, you can also use fopen

$params = array('http' => array(
    'method' => 'POST',
    'content' => 'toto=1&tata=2'
));

$ctx = stream_context_create($params);
$fp = @fopen($sUrl, 'rb', false, $ctx);
if (!$fp)
{
    throw new Exception("Problem with $sUrl, $php_errormsg");
}

$response = @stream_get_contents($fp);
if ($response === false) 
{
    throw new Exception("Problem reading data from $sUrl, $php_errormsg");
}

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

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

As per this the default is 2 MB for your <Connector>.

maxPostSize = The maximum size in bytes of the POST which will be handled by the container FORM URL parameter parsing. The limit can be disabled by setting this attribute to a value less than or equal to 0. If not specified, this attribute is set to 2097152 (2 megabytes).

Edit Tomcat's server.xml. In the <Connector> element, add an attribute maxPostSize and set a larger value (in bytes) to increase the limit.

Having said that, if this is the issue, you should have got an exception on the lines of Post data too big in tomcat

For Further Info

PUT = replace the ENTIRE RESOURCE with the new representation provided

PATCH = replace parts of the source resource with the values provided AND|OR other parts of the resource are updated that you havent provided (timestamps) AND|OR updating the resource effects other resources (relationships)

You could also use Watir or Watin to automate browsers. Watir is written for ruby and Watin is for .Net languages. Not sure if it's what you are looking for though.

You can create your own JSONObject then toString().

Remember run it in the background thread like doInBackground in AsyncTask.

OkHttp version > 4:

// create your json here
JSONObject jsonObject = new JSONObject();
try {
    jsonObject.put("KEY1", "VALUE1");
    jsonObject.put("KEY2", "VALUE2");
} catch (JSONException e) {
    e.printStackTrace();
}

val client = OkHttpClient()
val mediaType = "application/json; charset=utf-8".toMediaType()
val body = jsonObject.toString().toRequestBody(mediaType)
val request: Request = Request.Builder()
            .url("https://YOUR_URL/")
            .post(body)
            .build()

var response: Response? = null
try {
    response = client.newCall(request).execute()
    val resStr = response.body!!.string()
} catch (e: IOException) {
    e.printStackTrace()
}
   

OkHttp version 3:

// create your json here
JSONObject jsonObject = new JSONObject();
try {
    jsonObject.put("KEY1", "VALUE1");
    jsonObject.put("KEY2", "VALUE2");
} catch (JSONException e) {
    e.printStackTrace();
}

  OkHttpClient client = new OkHttpClient();
  MediaType JSON = MediaType.parse("application/json; charset=utf-8");
  // put your json here
  RequestBody body = RequestBody.create(JSON, jsonObject.toString());
  Request request = new Request.Builder()
                    .url("https://YOUR_URL/")
                    .post(body)
                    .build();

  Response response = null;
  try {
      response = client.newCall(request).execute();
      String resStr = response.body().string();
  } catch (IOException e) {
      e.printStackTrace();
  }

curl's --data will by default send Content-Type: application/x-www-form-urlencoded in the request header. However, when using Postman's raw body mode, Postman sends Content-Type: text/plain in the request header.

So to achieve the same thing as Postman, specify -H "Content-Type: text/plain" for curl:

curl -X POST -H "Content-Type: text/plain" --data "this is raw data" http://78.41.xx.xx:7778/

Note that if you want to watch the full request sent by Postman, you can enable debugging for packed app. Check this link for all instructions. Then you can inspect the app (right-click in Postman) and view all requests sent from Postman in the network tab :

You may also want to have a look at httplib2, with examples. I find using httplib2 is more concise than using the built-in HTTP modules.

The $.getJSON() method does an HTTP GET and not POST. You need to use $.post()

$.post(url, dataToBeSent, function(data, textStatus) {
  //data contains the JSON object
  //textStatus contains the status: success, error, etc
}, "json");

In that call, dataToBeSent could be anything you want, although if are sending the contents of a an html form, you can use the serialize method to create the data for the POST from your form.

var dataToBeSent = $("form").serialize();

@IBAction func btn_LogIn(sender: AnyObject) {

    let request = NSMutableURLRequest(URL: NSURL(string: "http://demo.hackerkernel.com/ios_api/login.php")!)
    request.HTTPMethod = "POST"
    let postString = "email: [email protected] & password: testtest"
    request.HTTPBody = postString.dataUsingEncoding(NSUTF8StringEncoding)
    let task = NSURLSession.sharedSession().dataTaskWithRequest(request){data, response, error in
        guard error == nil && data != nil else{
            print("error")
            return
        }
        if let httpStatus = response as? NSHTTPURLResponse where httpStatus.statusCode != 200{
            print("statusCode should be 200, but is \(httpStatus.statusCode)")
            print("response = \(response)")
        }
        let responseString = String(data: data!, encoding: NSUTF8StringEncoding)
        print("responseString = \(responseString)")
    }
    task.resume()
}

Here is the complete solution

html code,

create the text anf file upload fields as shown below

    <div class="form-group">
        <div>
            <label for="usr">User Name:</label>
            <input type="text" id="usr" ng-model="model.username">
        </div>
        <div>
            <label for="pwd">Password:</label>
            <input type="password" id="pwd" ng-model="model.password">
        </div><hr>
        <div>
            <div class="col-lg-6">
                <input type="file" file-model="model.somefile"/>
            </div>


        </div>
        <div>
            <label for="dob">Dob:</label>
            <input type="date" id="dob" ng-model="model.dob">
        </div>
        <div>
            <label for="email">Email:</label>
            <input type="email"id="email" ng-model="model.email">
        </div>


        <button type="submit" ng-click="saveData(model)" >Submit</button>

directive code

create a filemodel directive to parse file

.directive('fileModel', ['$parse', function ($parse) {
return {
    restrict: 'A',
    link: function(scope, element, attrs) {
        var model = $parse(attrs.fileModel);
        var modelSetter = model.assign;

        element.bind('change', function(){
            scope.$apply(function(){
                modelSetter(scope, element[0].files[0]);
            });
        });
    }
};}]);

Service code

append the file and fields to form data and do $http.post as shown below remember to keep 'Content-Type': undefined

 .service('fileUploadService', ['$http', function ($http) {
    this.uploadFileToUrl = function(file, username, password, dob, email, uploadUrl){
        var myFormData = new FormData();

        myFormData.append('file', file);
        myFormData.append('username', username);
        myFormData.append('password', password);
        myFormData.append('dob', dob);
        myFormData.append('email', email);


        $http.post(uploadUrl, myFormData, {
            transformRequest: angular.identity,
            headers: {'Content-Type': undefined}
        })
            .success(function(){

            })
            .error(function(){
            });
    }
}]);

In controller

Now in controller call the service by sending required data to be appended in parameters,

$scope.saveData  = function(model){
    var file = model.myFile;
    var uploadUrl = "/api/createUsers";
    fileUpload.uploadFileToUrl(file, model.username, model.password, model.dob, model.email, uploadUrl);
};

If you are using JQuery with Form plugin, you can use:

$('#myForm').ajaxSubmit({
    headers: {
        "foo": "bar"
    }
});

Source: https://stackoverflow.com/a/31955515/9469069

If you don't want to chunk your data together with the data callback you can always use the readable callback like this:

// Read Body when Available
request.on("readable", function(){
  request.body = '';
  while (null !== (request.body += request.read())){}
});

// Do something with it
request.on("end", function(){
  request.body //-> POST Parameters as String
});

This approach modifies the incoming request, but as soon as you finish your response the request will be garbage collected, so that should not be a problem.

An advanced approach would be to check the body size first, if you're afraid of huge bodies.

Here is my similar network kit library for uploading files as multipart form:

WebRequest *request = [[WebRequest alloc] initWithPath:@"...documents/create.json"];

// optional attributes
request.delegate = delegate;
request.notificationName = @"NotificationDocumentUploaded";
request.queue = myQueue;

NSMutableData *body = [NSMutableData data];
NSString *boundary = @"TeslaSchoolProjectFormBoundary";

[body appendPartName:@"document[name]" value:@"Test" boundary:boundary];
[body appendPartName:@"document[description]" value:@"This is a description" boundary:boundary];
[body appendPartName:@"document[category]" value:@"Drama" boundary:boundary];
...
[body appendPartName:@"commit" value:@"Save" boundary:boundary];
NSData *fileData = [[NSData alloc] initWithContentsOfURL:someFileURL];
[body appendPartFile:fileName name:@"document[file]" data:fileData mimeType:mimeType boundary:boundary];
[body appendData:[[NSString stringWithFormat:@"--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];

[request setHTTPBody:body];

NSString *bodyLength = [NSString stringWithFormat:@"%lu",(unsigned long)[body length]];
[request addValue:bodyLength forHTTPHeaderField:@"Content-Length"];
[request setValue:[NSString stringWithFormat:@"multipart/form-data; charset=utf-8; boundary=%@", boundary] forHTTPHeaderField:@"Content-Type"];


// optional values
[request addValue:@"gzip,deflate,sdch" forHTTPHeaderField:@"Accept-Encoding"];
[request addValue:@"max-age=0" forHTTPHeaderField:@"Cache-Control"];
[request addValue:@"text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8" forHTTPHeaderField:@"Accept"];
[request addValue:@"en-US,en;q=0.8,hr;q=0.6,it;q=0.4,sk;q=0.2,sl;q=0.2,sr;q=0.2" forHTTPHeaderField:@"Accept-Language"];


[request setHTTPMethod:@"POST"];
[WebRequestProcessor process:request];

Use the delegate for notifying about uploading progress.

Use the notificationName for notifying when request has finished.

Use the queue for adding this request into your operation queue so it will be processed in right time.

have you tried doing it without the JSON object and just passed two basicnamevaluepairs? also, it might have something to do with your serversettings

Update: this is a piece of code I use:

InputStream is = null;
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
    nameValuePairs.add(new BasicNameValuePair("lastupdate", lastupdate)); 

try {
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost(connection);
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        HttpResponse response = httpclient.execute(httppost);
        HttpEntity entity = response.getEntity();
        is = entity.getContent();
        Log.d("HTTP", "HTTP: OK");
    } catch (Exception e) {
        Log.e("HTTP", "Error in http connection " + e.toString());
    }

use CURL luke :) seriously, thats one of the best ways to do it AND you get the response.

Use the

Request.Form[]

for POST variables,

Request.QueryString[]

for GET.

Simple way is to use curl from command-line, for example:

DATA="foo=bar&baz=qux"
curl --data "$DATA" --request POST --header "Content-Type:application/x-www-form-urlencoded" http://example.com/api/callback | python -m json.tool

or here is example how to send raw POST request using Bash shell (JSON request):

exec 3<> /dev/tcp/example.com/80

DATA='{"email": "[email protected]"}'
LEN=$(printf "$DATA" | wc -c)

cat >&3 << EOF
POST /api/retrieveInfo HTTP/1.1
Host: example.com
User-Agent: Bash
Accept: */*
Content-Type:application/json
Content-Length: $LEN
Connection: close

$DATA
EOF

# Read response.
while read line <&3; do
   echo $line
done

Heres the method I used in my logging library: https://github.com/goktugyil/QorumLogs

This method fills html forms inside Google Forms. Hope it helps someone using Swift.

var url = NSURL(string: urlstring)

var request = NSMutableURLRequest(URL: url!)
request.HTTPMethod = "POST"
request.setValue("application/x-www-form-urlencoded; charset=utf-8", forHTTPHeaderField: "Content-Type")
request.HTTPBody = postData.dataUsingEncoding(NSUTF8StringEncoding)
var connection = NSURLConnection(request: request, delegate: nil, startImmediately: true)

 echo "Error uploading image";
}
}

No, you cannot do that. I invite you to read a POST definition.

Or this page: HTTP, request methods

Jerry's answer is great. However, it doesn't handle large responses. A simple change to handle this:

memset(response, 0, sizeof(response));
total = sizeof(response)-1;
received = 0;
do {
    printf("RESPONSE: %s\n", response);
    // HANDLE RESPONSE CHUCK HERE BY, FOR EXAMPLE, SAVING TO A FILE.
    memset(response, 0, sizeof(response));
    bytes = recv(sockfd, response, 1024, 0);
    if (bytes < 0)
        printf("ERROR reading response from socket");
    if (bytes == 0)
        break;
    received+=bytes;
} while (1); 

You can also use this approach in case you want to pass some http parameters and send a json request:

(note: I have added in some extra code just incase it helps any other future readers)

public void postJsonWithHttpParams() throws URISyntaxException, UnsupportedEncodingException, IOException {

    //add the http parameters you wish to pass
    List<NameValuePair> postParameters = new ArrayList<>();
    postParameters.add(new BasicNameValuePair("param1", "param1_value"));
    postParameters.add(new BasicNameValuePair("param2", "param2_value"));

    //Build the server URI together with the parameters you wish to pass
    URIBuilder uriBuilder = new URIBuilder("http://google.ug");
    uriBuilder.addParameters(postParameters);

    HttpPost postRequest = new HttpPost(uriBuilder.build());
    postRequest.setHeader("Content-Type", "application/json");

    //this is your JSON string you are sending as a request
    String yourJsonString = "{\"str1\":\"a value\",\"str2\":\"another value\"} ";

    //pass the json string request in the entity
    HttpEntity entity = new ByteArrayEntity(yourJsonString.getBytes("UTF-8"));
    postRequest.setEntity(entity);

    //create a socketfactory in order to use an http connection manager
    PlainConnectionSocketFactory plainSocketFactory = PlainConnectionSocketFactory.getSocketFactory();
    Registry<ConnectionSocketFactory> connSocketFactoryRegistry = RegistryBuilder.<ConnectionSocketFactory>create()
            .register("http", plainSocketFactory)
            .build();

    PoolingHttpClientConnectionManager connManager = new PoolingHttpClientConnectionManager(connSocketFactoryRegistry);

    connManager.setMaxTotal(20);
    connManager.setDefaultMaxPerRoute(20);

    RequestConfig defaultRequestConfig = RequestConfig.custom()
            .setSocketTimeout(HttpClientPool.connTimeout)
            .setConnectTimeout(HttpClientPool.connTimeout)
            .setConnectionRequestTimeout(HttpClientPool.readTimeout)
            .build();

    // Build the http client.
    CloseableHttpClient httpclient = HttpClients.custom()
            .setConnectionManager(connManager)
            .setDefaultRequestConfig(defaultRequestConfig)
            .build();

    CloseableHttpResponse response = httpclient.execute(postRequest);

    //Read the response
    String responseString = "";

    int statusCode = response.getStatusLine().getStatusCode();
    String message = response.getStatusLine().getReasonPhrase();

    HttpEntity responseHttpEntity = response.getEntity();

    InputStream content = responseHttpEntity.getContent();

    BufferedReader buffer = new BufferedReader(new InputStreamReader(content));
    String line;

    while ((line = buffer.readLine()) != null) {
        responseString += line;
    }

    //release all resources held by the responseHttpEntity
    EntityUtils.consume(responseHttpEntity);

    //close the stream
    response.close();

    // Close the connection manager.
    connManager.close();
}

In PHP, POST data limit is usually set by your php.ini. GET is limited by server/browser settings I believe - usually around 255 bytes.

Use simple counter on submit.

    var submitCounter = 0;
    function monitor() {
        submitCounter++;
        if (submitCounter < 2) {
            console.log('Submitted. Attempt: ' + submitCounter);
            return true;
        }
        console.log('Not Submitted. Attempt: ' + submitCounter);
        return false;
    }

And call monitor() function on submit the form.

    <form action="/someAction.go" onsubmit="return monitor();" method="POST">
        ....
        <input type="submit" value="Save Data">
    </form>

Perhaps you don't have to include the single quotes:

curl --request POST 'http://localhost/Service' --data "path=/xyz/pqr/test/&fileName=1.doc"

Update: Reading curl's manual, you could actually separate both fields with two --data:

curl --request POST 'http://localhost/Service' --data "path=/xyz/pqr/test/" --data "fileName=1.doc"

You could also try --data-binary:

curl --request POST 'http://localhost/Service' --data-binary "path=/xyz/pqr/test/" --data-binary "fileName=1.doc"

And --data-urlencode:

curl --request POST 'http://localhost/Service' --data-urlencode "path=/xyz/pqr/test/" --data-urlencode "fileName=1.doc"

A live example of using php curl_exec to do an HTTP post:

Put this in a file called foobar.php:

<?php
  $ch = curl_init();
  $skipper = "luxury assault recreational vehicle";
  $fields = array( 'penguins'=>$skipper, 'bestpony'=>'rainbowdash');
  $postvars = '';
  foreach($fields as $key=>$value) {
    $postvars .= $key . "=" . $value . "&";
  }
  $url = "http://www.google.com";
  curl_setopt($ch,CURLOPT_URL,$url);
  curl_setopt($ch,CURLOPT_POST, 1);                //0 for a get request
  curl_setopt($ch,CURLOPT_POSTFIELDS,$postvars);
  curl_setopt($ch,CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch,CURLOPT_CONNECTTIMEOUT ,3);
  curl_setopt($ch,CURLOPT_TIMEOUT, 20);
  $response = curl_exec($ch);
  print "curl response is:" . $response;
  curl_close ($ch);
?>

Then run it with the command php foobar.php, it dumps this kind of output to screen:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" 
"http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Title</title>

<meta http-equiv="Pragma" content="no-cache">
<meta http-equiv="Expires" content="0">
<body>
  A mountain of content...
</body>
</html>

So you did a PHP POST to www.google.com and sent it some data.

Had the server been programmed to read in the post variables, it could decide to do something different based upon that.

It is also possible to use the new button attribute called formtarget that was introduced with HTML5.

<form>
  <input type="submit" formtarget="_blank"/>
</form>

API Call

@Headers("Content-Type: application/json")
@POST("/set_data")
Call<CommonResponse> setPreferences(@Body RequestData request);

Note: Use GSON library of Retrofit

import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;

public class RequestData {

    @SerializedName("access_token")
    @Expose
    private String accessToken;

    @SerializedName("data")
    @Expose
    private Data data;
    // The above 'Data' is another similar class to add inner JSON objects. JSONObject within a JSONObject.

    public void setAccessToken(String accessToken) {
        this.accessToken = accessToken;
    }

    public void setData(Data data) {
        this.data = data;
    }
}

I guess that will help, rest all integration you might already have had and we don't need anything fancy to use above code snippet. It's working perfectly for me.

If you want the content string and this string does not have parameters you can use

    String line = null;
    BufferedReader reader = request.getReader();
    while ((line = reader.readLine()) != null){
        System.out.println(line);
    }

undefined index means that somewhere in the $_POST array, there isn't an index (key) for the key username.

You should be setting your posted values into variables for a more clean solution, and it's a good habit to get into.

If I was having a similar error, I'd do something like this:

$username = $_POST['username']; // you should really do some more logic to see if it's set first
echo $username;

If username didn't turn up, that'd mean I was screwing up somewhere. You can also,

var_dump($_POST);

To see what you're posting. var_dump is really useful as far as debugging. Check it out: var_dump

You can use the HttpWebRequest class to do so.

Example here:

using System;
using System.Net;
using System.Text;
using System.IO;


    public class Test
    {
        // Specify the URL to receive the request.
        public static void Main (string[] args)
        {
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create (args[0]);

            // Set some reasonable limits on resources used by this request
            request.MaximumAutomaticRedirections = 4;
            request.MaximumResponseHeadersLength = 4;
            // Set credentials to use for this request.
            request.Credentials = CredentialCache.DefaultCredentials;
            HttpWebResponse response = (HttpWebResponse)request.GetResponse ();

            Console.WriteLine ("Content length is {0}", response.ContentLength);
            Console.WriteLine ("Content type is {0}", response.ContentType);

            // Get the stream associated with the response.
            Stream receiveStream = response.GetResponseStream ();

            // Pipes the stream to a higher level stream reader with the required encoding format. 
            StreamReader readStream = new StreamReader (receiveStream, Encoding.UTF8);

            Console.WriteLine ("Response stream received.");
            Console.WriteLine (readStream.ReadToEnd ());
            response.Close ();
            readStream.Close ();
        }
    }

/*
The output from this example will vary depending on the value passed into Main 
but will be similar to the following:

Content length is 1542
Content type is text/html; charset=utf-8
Response stream received.
<html>
...
</html>

*/

There are two attributes, namely readonly and disabled, that can make a semi-read-only input. But there is a tiny difference between them.

<input type="text" readonly />
<input type="text" disabled />

• The readonly attribute makes your input text disabled, and users are not able to change it anymore.
• Not only will the disabled attribute make your input-text disabled(unchangeable) but also cannot it be submitted.

jQuery approach (1):

$("#inputID").prop("readonly", true);
$("#inputID").prop("disabled", true);

jQuery approach (2):

$("#inputID").attr("readonly","readonly");
$("#inputID").attr("disabled", "disabled");

JavaScript approach:

document.getElementById("inputID").readOnly = true;
document.getElementById("inputID").disabled = true;

PS disabled and readonly are standard html attributes. prop introduced with jQuery 1.6.

You could also just change the @RequestParam default required status to false so that HTTP response status code 400 is not generated. This will allow you to place the Annotations in any order you feel like.

@RequestParam(required = false)String name

Here is what works best for me:

<input type="submit" value="Delete" name="onDelete" />
<input type="submit" value="Save" name="onSave" />


public ActionResult Practice(MyModel model, string onSave, string onDelete)
{
    if (onDelete != null)
    {
        // Delete the object
        ...
        return EmptyResult();
    }

    // Save the object
    ...
    return EmptyResult();
}

Check that your network connection isn't redirecting.

I had this issue when on the wrong wifi and any web request was redirecting to a corporate login page.

Use json in dataType and send like this:

    $.ajax({
        url: "your url which return json",
        type: "POST",
        crossDomain: true,
        data: data,
        dataType: "json",
        success:function(result){
            alert(JSON.stringify(result));
        },
        error:function(xhr,status,error){
            alert(status);
        }
    });

and put this lines in your server side file:

if PHP:

header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: POST');
header('Access-Control-Max-Age: 1000');

if java:

response.addHeader( "Access-Control-Allow-Origin", "*" ); 
response.addHeader( "Access-Control-Allow-Methods", "POST" ); 
response.addHeader( "Access-Control-Max-Age", "1000" );

You could have your controller action take an object which would reflect the form input names and the default model binder will automatically create this object for you:

[HttpPost]
public ActionResult SubmitAction(SomeModel model)
{
    var value1 = model.SimpleProp1;
    var value2 = model.SimpleProp2;
    var value3 = model.ComplexProp1.SimpleProp1;
    ...

    ... return something ...
}

Another (obviously uglier) way is:

[HttpPost]
public ActionResult SubmitAction()
{
    var value1 = Request["SimpleProp1"];
    var value2 = Request["SimpleProp2"];
    var value3 = Request["ComplexProp1.SimpleProp1"];
    ...

    ... return something ...
}

You're looking for the --data-binary argument:

curl -i -X POST host:port/post-file \
  -H "Content-Type: text/xml" \
  --data-binary "@path/to/file"

In the example above, -i prints out all the headers so that you can see what's going on, and -X POST makes it explicit that this is a post. Both of these can be safely omitted without changing the behaviour on the wire. The path to the file needs to be preceded by an @ symbol, so curl knows to read from a file.

I'd like to expand on Obertklep's answer. In his example it is an NPM module called body-parser which is doing most of the work. Where he puts req.body.name, I believe he/she is using body-parser to get the contents of the name attribute(s) received when the form is submitted.

If you do not want to use Express, use querystring which is a built-in Node module. See the answers in the link below for an example of how to use querystring.

It might help to look at this answer, which is very similar to your quest.

This code will list out all the form variables that are being sent in a POST. This way you can see if you have the proper names of the post values.

string[] keys = Request.Form.AllKeys;
for (int i= 0; i < keys.Length; i++) 
{
   Response.Write(keys[i] + ": " + Request.Form[keys[i]] + "<br>");
}

The accepted answer throws a ProtocolException at:

OutputStream os = conn.getOutputStream();

because it does not enable the output for the URLConnection object. The solution should include this:

conn.setDoOutput(true);

to make it work.

Using HttpClient: as far as Windows 8 app development concerns, I came across this.

var client = new HttpClient();

var pairs = new List<KeyValuePair<string, string>>
    {
        new KeyValuePair<string, string>("pqpUserName", "admin"),
        new KeyValuePair<string, string>("password", "test@123")
    };

var content = new FormUrlEncodedContent(pairs);

var response = client.PostAsync("youruri", content).Result;

if (response.IsSuccessStatusCode)
{


}

You can also send data by overriding getBody() method of JsonObjectRequest class. As shown below.

    @Override
    public byte[] getBody()
    {

        JSONObject jsonObject = new JSONObject();
        String body = null;
        try
        {
            jsonObject.put("username", "user123");
            jsonObject.put("password", "Pass123");

            body = jsonObject.toString();
        } catch (JSONException e)
        {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        try
        {
            return body.toString().getBytes("utf-8");
        } catch (UnsupportedEncodingException e)
        {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return null;
    }

You can use the XMLHttpRequest object as follows:

xhr.open("POST", url, true);
xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8");
xhr.send(someStuff);

That code would post someStuff to url. Just make sure that when you create your XMLHttpRequest object, it will be cross-browser compatible. There are endless examples out there of how to do that.

It's been quite sometime since I asked this question. Now I understand it more clearly, I'm going to put a more complete answer to help others.

In Web API, it's very simple to remember how parameter binding is happening.

• if you POST simple types, Web API tries to bind it from the URL

• if you POST complex type, Web API tries to bind it from the body of the request (this uses a media-type formatter).

• If you want to bind a complex type from the URL, you'll use [FromUri] in your action parameter. The limitation of this is down to how long your data going to be and if it exceeds the url character limit.

  public IHttpActionResult Put([FromUri] ViewModel data) { ... }

• If you want to bind a simple type from the request body, you'll use [FromBody] in your action parameter.

  public IHttpActionResult Put([FromBody] string name) { ... }

as a side note, say you are making a PUT request (just a string) to update something. If you decide not to append it to the URL and pass as a complex type with just one property in the model, then the data parameter in jQuery ajax will look something like below. The object you pass to data parameter has only one property with empty property name.

var myName = 'ABC';
$.ajax({url:.., data: {'': myName}});

and your web api action will look something like below.

public IHttpActionResult Put([FromBody] string name){ ... }

This asp.net page explains it all. http://www.asp.net/web-api/overview/formats-and-model-binding/parameter-binding-in-aspnet-web-api

you should be able to access them from $_POST variable:

foreach ($_POST as $param_name => $param_val) {
    echo "Param: $param_name; Value: $param_val<br />\n";
}

Simple and Efficient Solution : use Volley

 StringRequest stringRequest = new StringRequest(Request.Method.GET, finalUrl ,
           new Response.Listener<String>() {
                    @Override
                    public void onResponse(String){
                        try {
                            JSONObject jsonObject = new JSONObject(response);
                            HashMap<String, Object> responseHashMap = new HashMap<>(Utility.toMap(jsonObject)) ;
                        } catch (JSONException e) {
                            e.printStackTrace();
                        }
                    }
                }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                Log.d("api", error.getMessage().toString());
            }
        });

        RequestQueue queue = Volley.newRequestQueue(context) ;
        queue.add(stringRequest) ;

You could use a negative look-ahead assertion:

^(?!tbd_).+

Or a negative look-behind assertion:

(^.{1,3}$|^.{4}(?<!tbd_).*)

Or just plain old character sets and alternations:

^([^t]|t($|[^b]|b($|[^d]|d($|[^_])))).*

In my case, I get it worked by defining the default value if the submitted data is empty. Here is what I finally did (using PHP7.3.5):

if(empty($_POST['auto'])){ $_POST['auto'] = ""; }

If anyone is looking for a rowspan on both the left AND on the right, here is how you can do it:

table { _x000D_
    border-collapse: collapse;_x000D_
}_x000D_
_x000D_
td {_x000D_
    padding: 20px; _x000D_
    border: 1px solid black; _x000D_
    text-align: center;_x000D_
}

<table>_x000D_
    <tbody>_x000D_
    <tr>_x000D_
        <td rowspan="2">LEFT</td>_x000D_
        <td> 1 </td>_x000D_
        <td> 2 </td>_x000D_
        <td> 3 </td>_x000D_
        <td> 4 </td>_x000D_
        <td rowspan="2">RIGHT</td>_x000D_
    </tr>_x000D_
    <tr>_x000D_
        <td> 5 </td>_x000D_
        <td> 6 </td>_x000D_
        <td> 7 </td>_x000D_
        <td> 8 </td>_x000D_
    </tr>_x000D_
    <tr>_x000D_
        <td> - </td>_x000D_
        <td> - </td>_x000D_
        <td> - </td>_x000D_
        <td> - </td>_x000D_
        <td> - </td>_x000D_
        <td> - </td>_x000D_
    </tr>_x000D_
    </tbody>_x000D_
</table>

Alternatively, if you want to add the LEFT and RIGHT to an existing rowset, you can achieve the same result by throwing them in with a collapsed colspan in between:

table {_x000D_
    border-collapse: collapse;_x000D_
}_x000D_
_x000D_
td {_x000D_
    padding: 20px; _x000D_
    border: 1px solid black; _x000D_
    text-align: center;_x000D_
}

<table>_x000D_
    <tbody>_x000D_
    <tr>_x000D_
        <td rowspan="3">LEFT</td>_x000D_
        <td colspan="4" style="padding: 0; border-bottom: solid 1px transparent;"></td>_x000D_
        <td rowspan="3">RIGHT</td>_x000D_
    </tr>_x000D_
    <tr>_x000D_
        <td> 1 </td>_x000D_
        <td> 2 </td>_x000D_
        <td> 3 </td>_x000D_
        <td> 4 </td>_x000D_
    </tr>_x000D_
    <tr>_x000D_
        <td> 5 </td>_x000D_
        <td> 6 </td>_x000D_
        <td> 7 </td>_x000D_
        <td> 8 </td>_x000D_
    </tr>_x000D_
    <tr>_x000D_
        <td> - </td>_x000D_
        <td> - </td>_x000D_
        <td> - </td>_x000D_
        <td> - </td>_x000D_
        <td> - </td>_x000D_
        <td> - </td>_x000D_
    </tr>_x000D_
    </tbody>_x000D_
</table>

Would not \\(.*?\\) work? That is the non-greedy syntax.

The origin of this error lies in the fact that each and every promise is expected to handle promise rejection i.e. have a .catch(...) . you can avoid the same by adding .catch(...) to a promise in the code as given below.

for example, the function PTest() will either resolve or reject a promise based on the value of a global variable somevar

var somevar = false;
var PTest = function () {
    return new Promise(function (resolve, reject) {
        if (somevar === true)
            resolve();
        else
            reject();
    });
}
var myfunc = PTest();
myfunc.then(function () {
     console.log("Promise Resolved");
}).catch(function () {
     console.log("Promise Rejected");
});

In some cases, the "unhandled promise rejection" message comes even if we have .catch(..) written for promises. It's all about how you write your code. The following code will generate "unhandled promise rejection" even though we are handling catch.

var somevar = false;
var PTest = function () {
    return new Promise(function (resolve, reject) {
        if (somevar === true)
            resolve();
        else
            reject();
    });
}
var myfunc = PTest();
myfunc.then(function () {
     console.log("Promise Resolved");
});
// See the Difference here
myfunc.catch(function () {
     console.log("Promise Rejected");
});

The difference is that you don't handle .catch(...) as chain but as separate. For some reason JavaScript engine treats it as promise without un-handled promise rejection.

You can also read lines w/o loop. Works in python3.6.

import os
import subprocess

process = subprocess.Popen(command, stdout=subprocess.PIPE)
list_of_byte_strings = process.stdout.readlines()

If we're talking about Request headers, you can create your own headers when doing XmlHttpRequests.

var request = new XMLHttpRequest();
request.setRequestHeader("X-Requested-With", "XMLHttpRequest");
request.open("GET", path, true);
request.send(null);

Try to slightly modify your code:

Sub forEachWs()
    Dim ws As Worksheet
    For Each ws In ActiveWorkbook.Worksheets
        Call resizingColumns(ws)
    Next
End Sub

Sub resizingColumns(ws As Worksheet)
    With ws
        .Range("A:A").ColumnWidth = 20.14
        .Range("B:B").ColumnWidth = 9.71
        .Range("C:C").ColumnWidth = 35.86
        .Range("D:D").ColumnWidth = 30.57
        .Range("E:E").ColumnWidth = 23.57
        .Range("F:F").ColumnWidth = 21.43
        .Range("G:G").ColumnWidth = 18.43
        .Range("H:H").ColumnWidth = 23.86
        .Range("i:I").ColumnWidth = 27.43
        .Range("J:J").ColumnWidth = 36.71
        .Range("K:K").ColumnWidth = 30.29
        .Range("L:L").ColumnWidth = 31.14
        .Range("M:M").ColumnWidth = 31
        .Range("N:N").ColumnWidth = 41.14
        .Range("O:O").ColumnWidth = 33.86
    End With
End Sub

Note, resizingColumns routine takes parametr - worksheet to which Ranges belongs.

Basically, when you're using Range("O:O") - code operats with range from ActiveSheet, that's why you should use With ws statement and then .Range("O:O").

And there is no need to use global variables (unless you are using them somewhere else)

Regex is a little quicker than the accepted answer (for my 23 MB test file) that I used. But there isn't a lot in it.

import re

bad_words = ['bad', 'naughty']

regex = f"^.*(:{'|'.join(bad_words)}).*\n"
subst = ""

with open('oldfile.txt') as oldfile:
    lines = oldfile.read()

result = re.sub(regex, subst, lines, re.MULTILINE) 

with open('newfile.txt', 'w') as newfile:
    newfile.write(result)

For MySql WorkBench, Please use below :

update emp as a
inner join department b on a.department_id=b.id
set a.department_name=b.name
where a.emp_id in (10,11,12); 

All above answers didn't work for me with CHROME as of 28 Jan 2014

my App launched properly from http://example.com/someresource/ links from apps like hangouts, gmail etc but not from within chrome browser.

to solve this, so that it launches properly from CHROME you have to set intent filter like this

<intent-filter>
    <action android:name="android.intent.action.VIEW" />

    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />

    <data
        android:host="example.com"
        android:pathPrefix="/someresource/"
        android:scheme="http" />
    <data
        android:host="www.example.com"
        android:pathPrefix="/someresource/"
        android:scheme="http" />
</intent-filter>

note the pathPrefix element

your app will now appear inside activity picker whenever user requests http://example.com/someresource/ pattern from chrome browser by clicking a link from google search results or any other website

;with C as

  select Rel.t2ID,
         Rel.t1ID,

                     sum(C1.Price) as Price,
                     C2.t1ID
              from C as C1
                inner join C as C2 
                  on C1.t2ID = C2.t2ID and
                     C2.rn = 1
              group by C1.t2ID, C2.t1ID
             ) as T1Sum
    on T2.ID = T1Sum.t2ID
  inner join @t1 as T1
    on T1.ID = T1Sum.t1ID

char arr[3] = "bo";

The arr takes the memory into the stack segment. which will be automatically free, if arr goes out of scope.

Save below in a test.bat and It'll work for you:

@echo off

net use Z: \\server\SharedFolderName password /user:domain\Username /persistent:yes

/persistent:yes flag will tell the computer to automatically reconnect this share on logon. Otherwise, you need to run the script again during each boot to map the drive.

For Example:

net use Z: \\WindowsServer123\g$ P@ssw0rd /user:Mynetdomain\Sysadmin /persistent:yes

Double number = new Double("5.25");
Double tDouble = 
  new BigDecimal(number).setScale(1, BigDecimal.ROUND_HALF_UP).doubleValue();

this will return it will return 5.3

Delete the working copy from the OS and check it out again is simplest, but obviously not a single command.

I had a similar error & this is what I found.

My environment details were as below: steps followed at my end

c:\>pip --version
pip 20.0.2 from c:\python37_64\lib\site-packages\pip (python 3.7)

C:\>python --version
Python 3.7.6

As per the documentation, apparently, python 3.7 already has the pickle package. So it does not require any additional download. I checked with the following command to make sure & it worked.

C:\Python\Experiements>python
Python 3.7.6 (tags/v3.7.6:43364a7ae0, Dec 19 2019, 00:42:30) [MSC v.1916 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import pickle
>>>

So, pip install pickle not required for python v3.7 for sure

If you want your script to return values, just do return [1,2,3] from a function wrapping your code but then you'd have to import your script from another script to even have any use for that information:

Return values (from a wrapping-function)

(again, this would have to be run by a separate Python script and be imported in order to even do any good):

import ...
def main():
    # calculate stuff
    return [1,2,3]

Exit codes as indicators

(This is generally just good for when you want to indicate to a governor what went wrong or simply the number of bugs/rows counted or w/e. Normally 0 is a good exit and >=1 is a bad exit but you could inter-prate them in any way you want to get data out of it)

import sys
# calculate and stuff
sys.exit(100)

And exit with a specific exit code depending on what you want that to tell your governor. I used exit codes when running script by a scheduling and monitoring environment to indicate what has happened.

(os._exit(100) also works, and is a bit more forceful)

Stdout as your relay

If not you'd have to use stdout to communicate with the outside world (like you've described). But that's generally a bad idea unless it's a parser executing your script and can catch whatever it is you're reporting to.

import sys
# calculate stuff
sys.stdout.write('Bugs: 5|Other: 10\n')
sys.stdout.flush()
sys.exit(0)

Are you running your script in a controlled scheduling environment then exit codes are the best way to go.

Files as conveyors

There's also the option to simply write information to a file, and store the result there.

# calculate
with open('finish.txt', 'wb') as fh:
    fh.write(str(5)+'\n')

And pick up the value/result from there. You could even do it in a CSV format for others to read simplistically.

Sockets as conveyors

If none of the above work, you can also use network sockets locally *(unix sockets is a great way on nix systems). These are a bit more intricate and deserve their own post/answer. But editing to add it here as it's a good option to communicate between processes. Especially if they should run multiple tasks and return values.

myPlugin.start($val); // Tried this, didn't work

It doesn't work because $val is undefined as far as JavaScript is concerned, i.e. the PHP code did not output anything for $val. Try viewing the source in your browser and here is what you'll see:

myPlugin.start(); // I tried this, and it didn't work

And

<?php myPlugin.start($val); ?> // This didn't work either

This doesn't work because PHP will try to treat myPlugin as a constant and when that fails it will try to treat it as the string 'myPlugin' which it will try to concatenate with the output of the PHP function start() and since that is undefined it will produce a fatal error.

And

 myPlugin.start(<?=$val?> // This works sometimes, but sometimes it fails

While this is most likely to work, since the PHP code is producing valid JavaScript with the expected arguments, if it fails, chances are it's because myPlugin isn't ready yet. Check your order of execution.

Also you should note that the PHP code output is insecure and should be filtered with json_encode().

EDIT

Because I didn't notice the missing parenthesis in myPlugin.start(<?=$val?> :-\

As @Second Rikudo points out, for it to work correctly $val would need to contain the closing parenthesis, for example: $val="42);"

Meaning that the PHP will now produce myPlugin.start(42); and will work as expected when executed by the JavaScript code.

COUNT is part of pig see the manual

LOGS= LOAD 'log';
LOGS_GROUP= GROUP LOGS ALL;
LOG_COUNT = FOREACH LOGS_GROUP GENERATE COUNT(LOGS);

The static modifier after import is for retrieving/using static fields of a class. One area in which I use import static is for retrieving constants from a class. We can also apply import static on static methods. Make sure to type import static because static import is wrong.

What is static import in Java - JavaRevisited - A very good resource to know more about import static.

I found this way to be a good one, without having to worry too much about charsets and arrays, or iconv:

function replace_accents($str) {
   $str = htmlentities($str, ENT_COMPAT, "UTF-8");
   $str = preg_replace('/&([a-zA-Z])(uml|acute|grave|circ|tilde|ring);/','$1',$str);
   return html_entity_decode($str);
}

i would recommend going to http://sourceforge.net/projects/py2exe/files/latest/download?source=files to download py2exe. Then make a python file named setup.py. Inside it, type

from distutils.core import setup
import py2exe
setup(console=['nameoffile.py'])

Save in your user folder Also save the file you want converted in that same folder

Run window's command prompt type in setup.py install py2exe

It should print many lines of code...

Next, open the dist folder.

Run the exe file.

If there are needed files for the program to work, move them to the folder

Copy/Send the dist folder to person.

Optional: Change the name of the dist folder

Hope it works!:)

Here's a function that uses .NET's System.IO classes directly:

function GetLineAt([String] $path, [Int32] $index)
{
    [System.IO.FileMode] $mode = [System.IO.FileMode]::Open;
    [System.IO.FileAccess] $access = [System.IO.FileAccess]::Read;
    [System.IO.FileShare] $share = [System.IO.FileShare]::Read;
    [Int32] $bufferSize = 16 * 1024;
    [System.IO.FileOptions] $options = [System.IO.FileOptions]::SequentialScan;
    [System.Text.Encoding] $defaultEncoding = [System.Text.Encoding]::UTF8;
    # FileStream(String, FileMode, FileAccess, FileShare, Int32, FileOptions) constructor
    # http://msdn.microsoft.com/library/d0y914c5.aspx
    [System.IO.FileStream] $input = New-Object `
        -TypeName 'System.IO.FileStream' `
        -ArgumentList ($path, $mode, $access, $share, $bufferSize, $options);
    # StreamReader(Stream, Encoding, Boolean, Int32) constructor
    # http://msdn.microsoft.com/library/ms143458.aspx
    [System.IO.StreamReader] $reader = New-Object `
        -TypeName 'System.IO.StreamReader' `
        -ArgumentList ($input, $defaultEncoding, $true, $bufferSize);
    [String] $line = $null;
    [Int32] $currentIndex = 0;

    try
    {
        while (($line = $reader.ReadLine()) -ne $null)
        {
            if ($currentIndex++ -eq $index)
            {
                return $line;
            }
        }
    }
    finally
    {
        # Close $reader and $input
        $reader.Close();
    }

    # There are less than ($index + 1) lines in the file
    return $null;
}

GetLineAt 'file.txt' 9;

Tweaking the $bufferSize variable might affect performance. A more concise version that uses default buffer sizes and doesn't provide optimization hints could look like this:

function GetLineAt([String] $path, [Int32] $index)
{
    # StreamReader(String, Boolean) constructor
    # http://msdn.microsoft.com/library/9y86s1a9.aspx
    [System.IO.StreamReader] $reader = New-Object `
        -TypeName 'System.IO.StreamReader' `
        -ArgumentList ($path, $true);
    [String] $line = $null;
    [Int32] $currentIndex = 0;

    try
    {
        while (($line = $reader.ReadLine()) -ne $null)
        {
            if ($currentIndex++ -eq $index)
            {
                return $line;
            }
        }
    }
    finally
    {

You can also do the following;

string json = myJObject.ToString(Newtonsoft.Json.Formatting.None);

Based on the accepted answer, for those who encountered a similar issue, with full schema qualification:

([MyDataBase].[MySchemaName].[MyTable])... results in an error, you need to be in the context of that DB

That is, the following will throw an error:

DBCC CHECKIDENT ([MyDataBase].[MySchemaName].[MyTable], RESEED, 0)

Enclose the fully-qualified table name with single quotes instead:

DBCC CHECKIDENT ('[MyDataBase].[MySchemaName].[MyTable]', RESEED, 0)

Apart from custom class or .Net 4.0 Tuples, since C# 7.0 there is a new feature called ValueTuple, which is a struct that can be used in this case. Instead of writing:

Tuple<string, int> t = new Tuple<string, int>("Hello", 4);

and access values through t.Item1 and t.Item2, you can simply do it like that:

(string message, int count) = ("Hello", 4);

or even:

(var message, var count) = ("Hello", 4);

This ought to do the trick: just limit the result to 1 row; if a row comes back the $lectureName is Assigned, otherwise it's Available.

function checkLectureStatus($lectureName)
{
    $con = connectvar();
    mysql_select_db("mydatabase", $con);
    $result = mysql_query(
        "SELECT * FROM preditors_assigned WHERE lecture_name='$lectureName' LIMIT 1");

    if(mysql_fetch_array($result) !== false)
        return 'Assigned';
    return 'Available';
}

My web host is stuck on version 5.1 of mysql so anyone like me that doesn't have the option of upgrading can follow these directions:

If Tuple has no key repetitions, it's Simple.

tup = [("A",0),("B",3),("C",5)]
dic = dict(tup)
print(dic)

If tuple has key repetitions.

tup = [("A",0),("B",3),("C",5),("A",9),("B",4)]
dic = {}
for i, j in tup:
    dic.setdefault(i,[]).append(j)
print(dic)

file_get_contents(php://input) - gets the raw POST data and you need to use this when you write APIs and need XML/JSON/... input that cannot be decoded to $_POST by PHP some example :

send by post JSON string

<input type="button" value= "click" onclick="fn()">
<script>
 function fn(){


    var js_obj = {plugin: 'jquery-json', version: 2.3};

    var encoded = JSON.stringify( js_obj );

var data= encoded


    $.ajax({
  type: "POST",
  url: '1.php',
  data: data,
  success: function(data){
    console.log(data);
  }

});

    }
</script>

1.php

//print_r($_POST); //empty!!! don't work ... 
var_dump( file_get_contents('php://input'));

Variable type String in Swift contains different functions compared to NSString in Objective-C . And as Sulthan mentioned,

Swift String doesn't implement RandomAccessIndex

What you can do is downcast your variable of type String to NSString (this is valid in Swift). This will give you access to the functions in NSString.

var str = "abcdefghi" as NSString
str.rangeOfString("c").locationx   // returns 2

You should use only

overflow-y:hidden; - Use this for hiding the Vertical scroll

overflow-x:auto; - Use this to show Horizontal scroll

Luke has mentioned as both hidden. so I have given this separately.

Option 2 is correct: The nested <ul> is a child of the <li> it belongs in.

If you validate, option 1 comes up as an error in html 5 -- credit: user3272456

Correct: <ul> as child of <li>

The proper way to make HTML nested list is with the nested <ul> as a child of the <li> to which it belongs. The nested list should be inside of the <li> element of the list in which it is nested.

<ul>
    <li>Parent/Item
        <ul>
            <li>Child/Subitem
            </li>
        </ul>
    </li>
</ul>

W3C Standard for Nesting Lists

A list item can contain another entire list — this is known as "nesting" a list. It is useful for things like tables of contents, such as the one at the start of this article:

1. Chapter One
   1. Section One
   2. Section Two
   3. Section Three
2. Chapter Two
3. Chapter Three

The key to nesting lists is to remember that the nested list should relate to one specific list item. To reflect that in the code, the nested list is contained inside that list item. The code for the list above looks something like this:

<ol>
  <li>Chapter One
    <ol>
      <li>Section One</li>
      <li>Section Two </li>
      <li>Section Three </li>
    </ol>
  </li>
  <li>Chapter Two</li>
  <li>Chapter Three  </li>
</ol>

Note how the nested list starts after the <li> and the text of the containing list item (“Chapter One”); then ends before the </li> of the containing list item. Nested lists often form the basis for website navigation menus, as they are a good way to define the hierarchical structure of the website.

Theoretically you can nest as many lists as you like, although in practice it can become confusing to nest lists too deeply. For very large lists, you may be better off splitting the content up into several lists with headings instead, or even splitting it up into separate pages.

Try this "html-approach" which is acceptable for small JS projects

function msg(animal,is) {
  console.log(animal, is.checked);   // Do stuff
}

<input type="checkbox" oninput="msg('dog', this)" />Do you have a dog? <br>
<input type="checkbox" oninput="msg('frog',this)" />Do you have a frog?<br>
...

To hide the prompt set xls.DisplayAlerts = False

ConflictResolution is not a true or false property, it should be xlLocalSessionChanges

Note that this has nothing to do with displaying the Overwrite prompt though!

Set xls = CreateObject("Excel.Application")    
xls.DisplayAlerts = False
Set wb = xls.Workbooks.Add
fullFilePath = importFolderPath & "\" & "A.xlsx"

wb.SaveAs fullFilePath, AccessMode:=xlExclusive,ConflictResolution:=Excel.XlSaveConflictResolution.xlLocalSessionChanges    
wb.Close (True)

I generally find the conditional command concatenation operators much more convenient than ERRORLEVEL.

yourCommand && (
  echo yourCommand was successful
) || (
  echo yourCommand failed
)

There is one complication you should be aware of. The error branch will fire if the last command in the success branch raises an error.

yourCommand && (
  someCommandThatMayFail
) || (
  echo This will fire if yourCommand or someCommandThatMayFail raises an error
)

The fix is to insert a harmless command that is guaranteed to succeed at the end of the success branch. I like to use (call ), which does nothing except set the ERRORLEVEL to 0. There is a corollary (call) that does nothing except set the ERRORLEVEL to 1.

yourCommand && (
  someCommandThatMayFail
  (call )
) || (
  echo This can only fire if yourCommand raises an error
)

See Foolproof way to check for nonzero (error) return code in windows batch file for examples of the intricacies needed when using ERRORLEVEL to detect errors.

As stated in the previous answers,

git push <remote-name> <local-branch-name>:<remote-branch-name>

is enough for pushing a local branch.

Your colleagues, can pull all remote branches (including new ones) with this command:

git remote update

Then, to make changes on the branch, the usual flow:

git checkout -b <local-branch-name> <remote-name>/<remote-branch-name>

If someone says you can't because only Windows can control the non-client area, they're wrong!

That's just a half-truth because Windows lets you specify the dimensions of the non-client area. The fact is, this is possible only throughout the Windows' kernel methods, and you're in .NET, not C/C++. Anyway, don't worry! P/Invoke was meant just for such things! Indeed, the whole of the Windows Form UI and Console application Std-I/O methods are offered using system calls. Hence, you'd have only to perform the right system calls to set the non-client area up, as documented in MSDN.

However, this is a really hard solution I came up with a lot of time ago. Luckily, as of .NET 4.5, you can use the WindowChrome class to adjust the non-client area like you want. Here you can get to start with.

In order to make things simpler and cleaner, I'll redirect you here, a guide to change the window border dimensions to whatever you want. By setting it to 0, you'll be able to implement your custom window border in place of the system's one.

I'm sorry for not posting a clear example, but later I will for sure.

SELECT * 
FROM table 
WHERE id = (SELECT MAX(id) FROM TABLE)

It is possible to define a function from inside another function. the inner function does not exist until the outer function gets executed.

echo function_exists("y") ? 'y is defined\n' : 'y is not defined \n';
$x=x(2);
echo function_exists("y") ? 'y is defined\n' : 'y is not defined \n';

Output

y is not defined

y is defined

Simple thing you can not call function y before executed x

Be careful if you have spaces in your string variables and you check for existence. Be sure to quote them properly.

if [ ! "${somepath}" ] || [ ! "${otherstring}" ] || [ ! "${barstring}" ] ; then

This may also happen if you have a faulty or accidental equation in your csv file. i.e - One of the cells in your csv file starts with an equals sign (=) (An excel equation) which will, in turn throw an error. If you fix, or remove this equation by getting rid of the equals sign, it should solve the ORA-06502 error.

Solution is:

while (dataGridView1.RowCount > 1)
{
    dataGridView1.Rows.RemoveAt(0);
}

Go to Google Cloud Console, select the project then IAM and Admin and Settings

now SHUT DOWN

Then you have to wait for the project deletion.

Javascript is single-threaded, so by nature there should not be a sleep function because sleeping will block the thread. setTimeout is a way to get around this by posting an event to the queue to be executed later without blocking the thread. But if you want a true sleep function, you can write something like this:

function sleep(miliseconds) {
   var currentTime = new Date().getTime();

   while (currentTime + miliseconds >= new Date().getTime()) {
   }
}

Note: The above code is NOT recommended.

I had a similar problem, and never find anything on the web after excessive searching.

I reviewed the pom.xml file and in the dependencies I changed the scope of the <dependency> it: <scope>test</scope> to <scope>compile</scope> .

Previously I was using it only for tests but I change the project's structure and never knew I hve to change this.

test: This scope indicates that the dependency is not required for normal use of the application, and is only available for the test compilation and execution phases.

compile: This is the default scope, used if none is specified. Compile dependencies are available in all classpaths of a project. Furthermore, those dependencies are propagated to dependent projects.

In Spark 2.0 (I didn't tested with earlier versions). Simply:

print myRDD.take(n)

Where n is the number of lines and myRDD is wc in your case.

You should use finish() when the user clicks on the button in order to go to the previous activity.

Button backButton = (Button)this.findViewById(R.id.back);
backButton.setOnClickListener(new OnClickListener() {
  @Override
  public void onClick(View v) {
    finish();
  }
});

Alternatively, if you really need to, you can try to trigger your own back key press:

this.dispatchKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_BACK));
this.dispatchKeyEvent(new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_BACK));

Execute both of these.

We can break both a $(selector).each() loop and a $.each() loop at a particular iteration by making the callback function return false. Returning non-false is the same as a continue statement in a for loop; it will skip immediately to the next iteration.

return false; // this is equivalent of 'break' for jQuery loop

return;       // this is equivalent of 'continue' for jQuery loop

Note that $(selector).each() and $.each() are different functions.

To my knowledge, there is sadly no CSS filter to colorise an element (perhaps with the use of some SVG filter magic, but I'm somewhat unfamiliar with that) and even if that wasn't the case, filters are basically only supported by webkit browsers.

With that said, you could still work around this and use a canvas to modify your image. Basically, you can draw an image element onto a canvas and then loop through the pixels, modifying the respective RGBA values to the colour you want.

However, canvases do come with some restrictions. Most importantly, you have to make sure that the image src comes from the same domain as the page. Otherwise the browser won't allow you to read or modify the pixel data of the canvas.

There is no built-in method for type casting of user defined objects in PHP. That said, here are several possible solutions:

1) Use a function like the one below to deserialize the object, alter the string so that the properties you need are included in the new object once it's deserialized.

function cast($obj, $to_class) {
  if(class_exists($to_class)) {
    $obj_in = serialize($obj);
    $obj_out = 'O:' . strlen($to_class) . ':"' . $to_class . '":' . substr($obj_in, $obj_in[2] + 7);
    return unserialize($obj_out);
  }
  else
    return false;
}

2) Alternatively, you could copy the object's properties using reflection / manually iterating through them all or using get_object_vars().

This article should enlighten you on the "dark corners of PHP" and implementing typecasting on the user level.

You need to hash the contents to come up with a digest. There are many hashes available but 10-characters is pretty small for the result set. Way back, people used CRC-32, which produces a 33-bit hash (basically 4 characters plus one bit). There is also CRC-64 which produces a 65-bit hash. MD5, which produces a 128-bit hash (16 bytes/characters) is considered broken for cryptographic purposes because two messages can be found which have the same hash. It should go without saying that any time you create a 16-byte digest out of an arbitrary length message you're going to end up with duplicates. The shorter the digest, the greater the risk of collisions.

However, your concern that the hash not be similar for two consecutive messages (whether integers or not) should be true with all hashes. Even a single bit change in the original message should produce a vastly different resulting digest.

So, using something like CRC-64 (and base-64'ing the result) should get you in the neighborhood you're looking for.

Definitely Docker for the win!

As you may know Vagrant is for virtual machine management whereas Docker is for software containers management. If you are not aware of the difference, here is: A software container can share the same machine and kernel with other software containers. Using containers you save money because you don't waste resources on multiple operating systems (kernels), you can pack more software per server keeping a good degree of isolation.

Of course is a new discipline to care with its own pitfals and challenges.

Go for Docker Swarm if your requirements cross the single machine resources limit.

if (Request.Browser.Type.Contains("Firefox")) // replace with your check
{
    ...
} 
else if (Request.Browser.Type.ToUpper().Contains("IE")) // replace with your check
{
    if (Request.Browser.MajorVersion  < 7)
    { 
        DoSomething(); 
    }
    ...
}
else { }

Use chr() and ord():

>>> chr(97)
'a'
>>> ord('a')
97

You could inject $routeParams to your controller and access all the params that where used when the route was resolved.

E.g.:

// route was: app.dev/backend/:type/:id

function MyCtrl($scope, $routeParams, $log) {
    // use the params
    $log.info($routeParams.type, $routeParams.id);
};

See angular $routeParams documentation for further information.

color and fill are separate aesthetics. Since you want to modify the color you need to use the corresponding scale:

d + scale_color_manual(values=c("#CC6666", "#9999CC"))

is what you want.

If you are not using section headers (or footers) already, you can use them to add arbitrary spacing to table cells. Instead of having one section with n rows, create a table with n sections with one row each.

Implement the tableView:heightForHeaderInSection: method to control the spacing.

You may also want to implement tableView:viewForHeaderInSection: to control what the spacing looks like.

The Header field of the Request is public. You may do this :

req.Header.Set("name", "value")

Looks like the installed driver was in bad state. Here is what I did to make it work:

1. Delete the device from Device Manager.
2. Rescan for hardware changes.
3. "Slate 21" will show up with "Unknown driver" status.
4. Click on "Update Driver" and select /extras/google/usb_driver
5. Device Manager will find the driver and warn you about installing it. Select "Yes."

This time the device got installed properly.

Note that I didn't have to modify winusb.inf file or update any other driver.

Hope this helps.

Very easy to use select option submit

<select name="sortby" onchange="this.form.submit()">
       <option value="">Featured</option>
       <option value="asc" >Price: Low to High</option>
        <option value="desc">Price: High to Low</option>                                   
</select>

From JavaScript, since the Github API is CORS enabled:

fetch('https://api.github.com/repos/webdev23/source_control_sentry')
  .then(v => v.json()).then((function(v){
   console.log(v['size'] + "KB")
  })
)

Reflection resistant Singleton pattern:

public sealed class Singleton
{
    public static Singleton Instance => _lazy.Value;
    private static Lazy<Singleton, Func<int>> _lazy { get; }

    static Singleton()
    {
        var i = 0;
        _lazy = new Lazy<Singleton, Func<int>>(() =>
        {
            i++;
            return new Singleton();
        }, () => i);
    }

    private Singleton()
    {
        if (_lazy.Metadata() == 0 || _lazy.IsValueCreated)
            throw new Exception("Singleton creation exception");
    }

    public void Run()
    {
        Console.WriteLine("Singleton called");
    }
}

Try this code:

 alert(typeof(1) == "number");

ObservableCollection < T > has a constructor overload which takes IEnumerable < T >

Example for a List of int:

ObservableCollection<int> myCollection = new ObservableCollection<int>(myList);

One more example for a List of ObjectA:

ObservableCollection<ObjectA> myCollection = new ObservableCollection<ObjectA>(myList as List<ObjectA>);

Hold shift and right click on SQL Server Mangement studion icon. You can Run as other windows account user.

You should write something like that :

var text = "this is some sample text that i want to replace";
var new_text = text.replace("want", "dont want");
document.write(new_text);

This is what worked for me in Chrome and Firefox! This will open the little print window and close it automatically once you've clicked print.

var printContents = document.getElementById('div-id-selector').innerHTML;
            var popupWin = window.open('', '_blank', 'width=800,height=800,scrollbars=no,menubar=no,toolbar=no,location=no,status=no,titlebar=no,top=50');
            popupWin.window.focus();
            popupWin.document.open();
            popupWin.document.write('<!DOCTYPE html><html><head><title>TITLE OF THE PRINT OUT</title>' 
                                    +'<link rel="stylesheet" type="text/css" href="app/directory/file.css" />' 
                                    +'</head><body onload="window.print(); window.close();"><div>' 
                                    + printContents + '</div></html>');
            popupWin.document.close();

I don't know if there's any solution to do this in a database-agnostic way, since you most likely will need some form of string manipulation, and those are typically different between vendors.

For SQL Server 2005 and up, you could use:

SELECT
     r.ID, r.Name,
     Resources = STUFF(
       (SELECT ','+a.Name
        FROM dbo.Applications a
        INNER JOIN dbo.ApplicationsResources ar ON ar.app_id = a.id
        WHERE ar.resource_id = r.id
        FOR XML PATH('')), 1, 1, '')
FROM
     dbo.Resources r

It uses the SQL Server 2005 FOR XML PATH construct to list the subitems (the applications for a given resource) as a comma-separated list.

In case of Request to a REST Service:

You need to allow the CORS (cross origin sharing of resources) on the endpoint of your REST Service with Spring annotation:

@CrossOrigin(origins = "http://localhost:8080")

Very good tutorial: https://spring.io/guides/gs/rest-service-cors/

Rather than use "d", why not "p". I am not sure if the "p *" will work. I didn't try that. You can; however use the following script"

#!/bin/bash
#

MAIL_INDEX=$(printf 'h a\nq\n' | mail | egrep -o '[0-9]* unread' | awk '{print $1}')

markAllRead=
for (( i=1; i<=$MAIL_INDEX; i++ ))
do
   markAllRead=$markAllRead"p $i\n"
done
markAllRead=$markAllRead"q\n"
printf "$markAllRead" | mail

Why do you need a cursor at all? Your entire segment of code can be replaced by this, which will run a lot faster on large numbers of rows.

UPDATE tarinvoice set confirmtocntctkey = PrimaryCntctKey 
FROM tarinvoice INNER JOIN tarcustomer ON tarinvoice.custkey = tarcustomer.custkey
WHERE confirmtocntctkey is null and tranno like '%115876'

If it is inline, the browser should attempt to render it within the browser window. If it cannot, it will resort to an external program, prompting the user.

With attachment, it will immediately go to the user, and not try to load it in the browser, whether it can or not.

print locals()

edit continued from comment.

To make it look a little prettier when printing:

import sys, pprint
sys.displayhook = pprint.pprint
locals()

That should give you a more vertical printout.

Here is what you need to do. First make sure you are in branch that you don't want to pull. For example if you have master and develop branch, and you are trying to pull develop branch then stay in master branch.

git checkout master

Then,

git pull origin develop

I tried installing the module locally with version and it worked!!

npm install request@^2.*

Thanks.

Python indexing starts at 0 (rather than 1), so your assignment "r[1,:] = r0" defines the second (i.e. index 1) element of r and leaves the first (index 0) element as a pair of zeros. The first value of i in your for loop is 0, so rr gets the square root of the dot product of the first entry in r with itself (which is 0), and the division by rr in the subsequent line throws the error.

Turns out you don't have to do much at all.

See below - the parameter x will contain the full HTTP body (which is XML in our case).

@POST
public Response go(String x) throws IOException {
    ...
}

One way to convert to string is to use astype:

total_rows['ColumnID'] = total_rows['ColumnID'].astype(str)

However, perhaps you are looking for the to_json function, which will convert keys to valid json (and therefore your keys to strings):

In [11]: df = pd.DataFrame([['A', 2], ['A', 4], ['B', 6]])

In [12]: df.to_json()
Out[12]: '{"0":{"0":"A","1":"A","2":"B"},"1":{"0":2,"1":4,"2":6}}'

In [13]: df[0].to_json()
Out[13]: '{"0":"A","1":"A","2":"B"}'

Note: you can pass in a buffer/file to save this to, along with some other options...

Updated June 2020

It is no longer possible... allegedly. If you have a Facebook or Instagram dedicated contact (because you work in either a big agency or with a big client) it may potentially be possible depending on your use case, but it's highly discouraged.

Before December 2019:

It is now "possible":

https://developers.facebook.com/docs/instagram-api/content-publishing

The Content Publishing API is a subset of Instagram Graph API endpoints that allow you to publish media objects. Publishing media objects with this API is a two step process — you first create a media object container, then publish the container on your Business Account.

Its worth noting that "The Content Publishing API is in closed beta with Facebook Marketing Partners and Instagram Partners only. We are not accepting new applicants at this time." from https://stackoverflow.com/a/49677468/445887

<a href="/index2.php?option=com_jumi&amp;fileid=3&amp;Itemid=11"
   onclick="window.open(this.href,'targetWindow',
                                   `toolbar=no,
                                    location=no,
                                    status=no,
                                    menubar=no,
                                    scrollbars=yes,
                                    resizable=yes,
                                    width=SomeSize,
                                    height=SomeSize`);
 return false;">Popup link</a>

Where width and height are pixels without units (width=400 not width=400px).

In most browsers it will not work if it is not written without line breaks, once the variables are setup have everything in one line:

<a href="/index2.php?option=com_jumi&amp;fileid=3&amp;Itemid=11" onclick="window.open(this.href,'targetWindow','toolbar=no,location=no,status=no,menubar=no,scrollbars=yes,resizable=yes,width=SomeSize,height=SomeSize'); return false;">Popup link</a> 

For using custom drawable:

<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:fromDegrees="0"
android:toDegrees="360"
android:drawable="@drawable/my_drawable"
android:pivotX="50%"
android:pivotY="50%" />

(add under res/drawable progress.xml). my_drawable may be xml, png

Then in your layout use

<ProgressBar
        android:id="@+id/progressBar"
        android:indeterminateDrawable="@drawable/progress_circle"
...
/>

What's the difference between "include" and "require" in Ruby?

Answer:

The include and require methods do very different things.

The require method does what include does in most other programming languages: run another file. It also tracks what you've required in the past and won't require the same file twice. To run another file without this added functionality, you can use the load method.

The include method takes all the methods from another module and includes them into the current module. This is a language-level thing as opposed to a file-level thing as with require. The include method is the primary way to "extend" classes with other modules (usually referred to as mix-ins). For example, if your class defines the method "each", you can include the mixin module Enumerable and it can act as a collection. This can be confusing as the include verb is used very differently in other languages.

Source

So if you just want to use a module, rather than extend it or do a mix-in, then you'll want to use require.

Oddly enough, Ruby's require is analogous to C's include, while Ruby's include is almost nothing like C's include.

The solution seems to be to add multiple @font-face rules, for example:

@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans.ttf");
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-Bold.ttf");
    font-weight: bold;
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-Oblique.ttf");
    font-style: italic, oblique;
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-BoldOblique.ttf");
    font-weight: bold;
    font-style: italic, oblique;
}

By the way, it would seem Google Chrome doesn't know about the format("ttf") argument, so you might want to skip that.

(This answer was correct for the CSS 2 specification. CSS3 only allows for one font-style rather than a comma-separated list.)

func readToDisplayUsingFile1(f *os.File){
    defer f.Close()
    reader := bufio.NewReader(f)
    contents, _ := ioutil.ReadAll(reader)
    lines := strings.Split(string(contents), '\n')
}

or

func readToDisplayUsingFile1(f *os.File){
    defer f.Close()
    slice := make([]string,0)

    reader := bufio.NewReader(f)

    for{

    str, err := reader.ReadString('\n')
    if err == io.EOF{
        break
    }

        slice = append(slice, str)
    }

If you using windows authentication make sure that password of the user hasn't expired. An expired password can explain this error. This was the problem in my case.

A better solution is not to make your page dependable on zoom settings. If you set limits like the one you are proposing, you are limiting accessibility. If someone cannot read your text well, they just won't be able to change that. I would use proper CSS to make it look nice in any zoom.

If your really insist, take a look at this question on how to detect zoom level using JavaScript (nightmare!): How to detect page zoom level in all modern browsers?

Change

from urllib.request import urlopen

to

from urllib import urlopen

I was able to solve this problem by changing like this. For Python2.7 in macOS10.14

Also note that setting a header to "text/plain" will result in all html and php (in part) printing the characters on the screen as TEXT, not as HTML. So be aware of possible HTML not parsing when using text type plain.

Using:

header('Content-type: text/html; charset=utf-8');

Can return HTML and PHP as well. Not just text.

HTTP and HTTPS:

const getScript = (url) => {
    return new Promise((resolve, reject) => {
        const http      = require('http'),
              https     = require('https');

        let client = http;

        if (url.toString().indexOf("https") === 0) {
            client = https;
        }

        client.get(url, (resp) => {
            let data = '';

            // A chunk of data has been recieved.
            resp.on('data', (chunk) => {
                data += chunk;

            // The whole response has been received. Print out the result.
            resp.on('end', () => {
                resolve(data);
            });

        }).on("error", (err) => {
            reject(err);

If you know you will want a 'c' key, but do not know the value, insert 'c' with a dummy value when you create the dict.

d1 = OrderedDict([('c', None), ('a', '1'), ('b', '2')])

and change the value later.

d1['c'] = 3

1. run in terminal adb logcat *:S ReactNative:V ReactNativeJS:V
2. open project in Android Studio, open logcat (button on the bottom panel)
3. run in terminal react-native run-android

After building, you should see detail logs in Android Studio in logcat.

In addition to the 3 floated column structure (which I would suggest as well), you have to insert a clearfix to prevent layoutproblems with elements after the columncontainer (keep the columncontainer in the flow, so to speak...).

<div id="contentBox" class="clearfix">
....
</div>

CSS:

.clearfix { zoom: 1; }
.clearfix:before, .clearfix:after { content: "\0020"; display: block; height: 0; overflow: hidden; }
.clearfix:after { clear: both; }

Try this It is working for me..

The syntax is GetFiles(string path, string searchPattern);

var filePath = Server.MapPath("~/App_Data/");
string[] filePaths = Directory.GetFiles(@filePath, "*.*");

This code will return all the files inside App_Data folder.

The second parameter . indicates the searchPattern with File Extension where the first * is for file name and second is for format of the file or File Extension like (*.png - any file name with .png format.

Since TypeScript 3.7 was released you can use optional chaining now.

Property example:

let x = foo?.bar.baz();

This is equvalent to:

let x = (foo === null || foo === undefined) ?
    undefined :
    foo.bar.baz();

Moreover you can call:

Optional Call

function(otherFn: (par: string) => void) {
   otherFn?.("some value");
}

otherFn will be called only if otherFn won't be equal to null or undefined

Usage optional chaining in IF statement

This:

if (someObj && someObj.someProperty) {
    // ...
}

can be replaced now with this

if (someObj?.someProperty) {
    // ...
}

As mentionned in comments: you need a way to send your static files to the client. This can be achieved with a reverse proxy like Nginx, or simply using express.static().

Put all your "static" (css, js, images) files in a folder dedicated to it, different from where you put your "views" (html files in your case). I'll call it static for the example. Once it's done, add this line in your server code:

app.use("/static", express.static('./static/'));

This will effectively serve every file in your "static" folder via the /static route.

Querying your index.js file in the client thus becomes:

<script src="static/index.js"></script>

Laravel Server Requirements mention that BCMath, Ctype, JSON, Mbstring, OpenSSL, PDO, Tokenizer, and XML extensions are required. Most of the extensions are installed and enabled by default.

You can run the following command in Ubuntu to make sure the extensions are installed.

sudo apt install openssl php-common php-curl php-json php-mbstring php-mysql php-xml php-zip

PHP version specific installation (if PHP 7.4 installed)

sudo apt install php7.4-common php7.4-bcmath openssl php7.4-json php7.4-mbstring

You may need other PHP extensions for your composer packages. Find from links below.

Late to answer but might help someone else, here is how to do it without removing the 'multiple' attribute.

$('.myDropdown').chosen({
    //Here you can change the value of the maximum allowed options
    max_selected_options: 1
});

For my case it was the wrong baud rate. It calls this command:

C:\Program Files (x86)\Arduino\hardware\tools\avr/bin/avrdude -CC:\Program Files (x86)\Arduino\hardware\tools\avr/etc/avrdude.conf -v -patmega328p -carduino -PCOM4 **-b57600** -D -Uflash:w:C:\Users\Vahid\AppData\Local\Temp\arduino_build_527841/AnalogReadSerial.ino.hex:i 

As you can see, the baud rate is set to 57600. When you remove this argument (-b57600) and run it in command line it works fine.

Newest version of C# - C# 7.1 allows to create async console app. To enable C# 7.1 in project, you have to upgrade your VS to at least 15.3, and change C# version to C# 7.1 or C# latest minor version. To do this, go to Project properties -> Build -> Advanced -> Language version.

After this, following code will work:

internal class Program
{
    public static async Task Main(string[] args)
    {
         (...)
    }

I know that this question is accepted and has a bit of age but this might be helpful for some people who still find it relevant. Although the outcome is not a full RESTful API the API Builder mini lib for PHP allows you to easily transform MySQL databases into web accessible JSON APIs.

Since I've already been where you are right now, I think I can "answer" you.

The fact is there is no easy way to make a GUI. GUI's are highly dependent on platform and OS specific code, that's why you should start reading your target platform/OS documentation on window management APIs. The good thing is: there are plenty of libraries that address these limitations and abstract architecture differences into a single multi-platform API. Those suggested before, GTK and Qt, are some of these libraries.

But even these are a little too complicated, since lots of new concepts, data types, namespaces and classes are introduced, all at once. For this reason, they use to come bundled with some GUI WYSIWYG editor. They pretty much make programming software with GUIs possible.

To sum it up, there are also non free "environments" for GUI development such as Visual Studio from Microsoft. For those with Delphi experience backgrounds, Visual Studio may be more familiar. There are also free alternatives to the full Visual Studio environment supplied from Microsoft: Visual Studio Express, which is more than enough for starting on GUI development.

Assuming you also want to strip whitespace at beginning and end of each line, you can map the string strip function to the list returned by readlines:

map(str.strip, open('filename').readlines())

In IIS set the App Pool Identity As Service Account user or Administrator Account or ant account which has permission to do the operation on that DataBase.

The question is not clearly posed. The reason is that git add has two meanings:

1. adding a new file to the staging area, then undo with git rm --cached file.
2. adding a modified file to the staging area, then undo with git reset HEAD file.

If in doubt, use

git reset HEAD file

Because it does the expected thing in both cases.

Warning: if you do git rm --cached file on a file that was modified (a file that existed before in the repository), then the file will be removed on git commit! It will still exist in your file system, but if anybody else pulls your commit, the file will be deleted from their work tree.

git status will tell you if the file was a new file or modified:

On branch master
Changes to be committed:
  (use "git reset HEAD <file>..." to unstage)

    new file:   my_new_file.txt
    modified:   my_modified_file.txt

In .NET System.String (aka string) is a immutable object. That means when you create an object you can not change it's value afterwards. You can only recreate a immutable object.

System.Text.StringBuilder is mutable equivalent of System.String and you can chane its value

For Example:

class Program
{
    static void Main(string[] args)
    {

        System.String str = "inital value";
        str = "\nsecond value";
        str = "\nthird value";

        StringBuilder sb = new StringBuilder();
        sb.Append("initial value");
        sb.AppendLine("second value");
        sb.AppendLine("third value");
    }
}

Generates following MSIL : If you investigate the code. You will see that whenever you chane an object of System.String you are actually creating new one. But in System.Text.StringBuilder whenever you change the value of text you dont recreate the object.

I found it strangely difficult to locate the python docs for __enter__ and __exit__ methods by Googling, so to help others here is the link:

https://docs.python.org/2/reference/datamodel.html#with-statement-context-managers
https://docs.python.org/3/reference/datamodel.html#with-statement-context-managers
(detail is the same for both versions)

object.__enter__(self)
Enter the runtime context related to this object. The with statement will bind this method’s return value to the target(s) specified in the as clause of the statement, if any.

object.__exit__(self, exc_type, exc_value, traceback)
Exit the runtime context related to this object. The parameters describe the exception that caused the context to be exited. If the context was exited without an exception, all three arguments will be None.

If an exception is supplied, and the method wishes to suppress the exception (i.e., prevent it from being propagated), it should return a true value. Otherwise, the exception will be processed normally upon exit from this method.

Note that __exit__() methods should not reraise the passed-in exception; this is the caller’s responsibility.

I was hoping for a clear description of the __exit__ method arguments. This is lacking but we can deduce them...

Presumably exc_type is the class of the exception.

It says you should not re-raise the passed-in exception. This suggests to us that one of the arguments might be an actual Exception instance ...or maybe you're supposed to instantiate it yourself from the type and value?

We can answer by looking at this article:
http://effbot.org/zone/python-with-statement.htm

For example, the following __exit__ method swallows any TypeError, but lets all other exceptions through:

def __exit__(self, type, value, traceback):
    return isinstance(value, TypeError)

...so clearly value is an Exception instance.

And presumably traceback is a Python traceback object.

The key to all this is SCOPE.

You need to encapsulate the "parent" (parent object) of the property you want to define as it's own instantiated object, and then you can make references to sibling properties using the key word this

It's very, very important to remember that if you refer to this without first so doing, then this will refer to the outer scope... which will be the window object.

var x = 9   //this is really window.x
var bar = {
  x: 1,
  y: 2,
  foo: new function(){
    this.a = 5, //assign value
    this.b = 6,
    this.c = this.a + this.b;  // 11
  },
  z: this.x   // 9 (not 1 as you might expect, b/c *this* refers `window` object)
};

You can move Application.java to a folder under the java.

 function addValueInObject(value, object, key) {

        var addMoreOptions = eval('{"'  + key + '":' +  value + '}');

        if(addMoreOptions != null) {
            var textObject = JSON.stringify(object);
            textObject = textObject.substring(1,textObject.length-1);
            var AddElement = JSON.stringify(addMoreOptions);
            object = eval('{' + textObject +','+  AddElement.substring(1,AddElement.length-1) + '}');
        }
        return object;
    }

addValueInObject('sdfasfas', yourObject, 'keyname');

OR:

var obj = {'key':'value'};

obj.key2 = 'value2';

If someone searching how to toggle header so in componentDidMount write something like:

  this.props.navigation.setParams({
      hideHeader: true,
  });

When

static navigationOptions = ({ navigation }) => {
    const {params = {}} = navigation.state;

    if (params.hideHeader) {
      return {
        header: null,
      }
    }

    return {
        headerLeft: <Text>Hi</Text>,
        headerRight: <Text>Hi</Text>,
        headerTitle: <Text>Hi</Text>
    };
};

And somewhere when event finish job:

this.props.navigation.setParams({
  hideHeader: false,
});

Usual python3 log manager works for me with tensorflow==1.11.0:

import logging
logging.getLogger('tensorflow').setLevel(logging.INFO)

h2.text-left{
  position:relative;
  top:50%;
  transform: translateY(-50%);
  -webkit-transform: translateY(-50%);
  -ms-transform: translateY(-50%);
}

Explanation:

The top:50% style essentially pushes the header element down 50% from the top of the parent element. The translateY stylings also act in a similar manner by moving then element down 50% from the top.

Please note that this works well for headers with 1 (maybe 2) lines of text as this simply moves the top of the header element down 50% and then the rest of the content fills in below that, which means that with multiple lines of text it would appear to be slightly below vertically aligned.

A possible fix for multiple lines would be to use a percentage slightly less than 50%.

Yes. I don't have any examples that I've done personally available right now. I'll post later when I find some. Basically you'll use reflection to load the assembly and then to pull whatever types you need for it.

In the meantime, this link should get you started:

Using reflection to load unreferenced assemblies at runtime

I needed this instead of using padding because I used inline-block containers to display a series of individual events in a workflow timeline. The last event in the timeline needed no arrow after it.

Ended up with something like:

.transaction-tile:after {
  content: "\f105";
}

.transaction-tile:last-child:after {
  content: "\00a0";
}

Used fontawesome for the gt (chevron) character. For whatever reason "content: none;" was producing alignment issues on the last tile.

You can only use absolute path http://grand-shopping.com/<"some folder"> is not an absolute path.

Either you can use a path inside the application which is vurneable or you can use server specific path like in

windows -> C:/Users/puneet verma/Downloads/
linux -> /opt/Downloads/

In my understanding, Get-Content eliminates ALL newlines/carriage returns when it rolls your text file through the pipeline. To do multiline regexes, you have to re-combine your string array into one giant string. I do something like:

$text = [string]::Join("`n", (Get-Content test.txt))
[regex]::Replace($text, "t`n", "ting`na ", "Singleline")

Clarification: small files only folks! Please don't try this on your 40 GB log file :)

In those situations where I needed a true infinite loop, I've always used

I was trying to use CURL to do some https API calls with php and ran into this problem. I noticed a recommendation on the php site which got me up and running: http://php.net/manual/en/function.curl-setopt.php#110457

Please everyone, stop setting CURLOPT_SSL_VERIFYPEER to false or 0. If your PHP installation doesn't have an up-to-date CA root certificate bundle, download the one at the curl website and save it on your server:

http://curl.haxx.se/docs/caextract.html

Then set a path to it in your php.ini file, e.g. on Windows:

curl.cainfo=c:\php\cacert.pem

Turning off CURLOPT_SSL_VERIFYPEER allows man in the middle (MITM) attacks, which you don't want!

Yes, in order for the z-index to work, you'll need to give the element a position: absolute or a position: relative property.

But... pay attention to parents!

You have to go up the nodes of the elements to check if at the level of the common parent the first descendants have a defined z-index.

All other descendants can never be in the foreground if at the base there is a lower definite z-index.

In this snippet example, div1-2-1 has a z-index of 1000 but is nevertheless under the div1-1-1 which has a z-index of 3.

This is because div1-1 has a z-index greater than div1-2.

.div {
  
}

#div1 {
  z-index: 1;
  position: absolute;

This question & answer lead me to believe that IQueryable require an active context for its operation. That means you should try this instead:

try
{
    IQueryable<User> users;

    using (var dataContext = new dataContext())
    {
        users = dataContext.Users.Where(x => x.AccountID == accountId && x.IsAdmin == false);

        if(users.Any() == false)
        {
            return null;
        }
        else
        {
            return users.Select(x => x.ToInfo()).ToList(); // this line is the problem
        }
    }


}
catch (Exception ex)
{
    ...
}

To convert array to object using stdClass just add (object) to array u declare.

EX:

echo $array['value'];
echo $object->value;

to convert object to array

$obj = (object)$array;

to convert array to object

$arr = (array)$object

with these methods you can swap between array and object very easily.

Another method is to use json

$object = json_decode(json_encode($array), FALSE);

But this is a much more memory intensive way to do and is not supported by versions of PHP <= 5.1

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

There are instructions on how to install sshpass here:

https://gist.github.com/arunoda/7790979

For Mac you will need to install xcode and command line tools then use the unofficial Homewbrew command:

brew install https://raw.githubusercontent.com/kadwanev/bigboybrew/master/Library/Formula/sshpass.rb

There's actually a pretty easy way to do this. The code should be something like:

<script type="test/javascript">

    function showcontent(x){

      if(window.XMLHttpRequest) {
        xmlhttp = new XMLHttpRequest();
      } else {
        xmlhttp = new ActiveXObject('Microsoft.XMLHTTP');
      }

      xmlhttp.onreadystatechange = function() {
        if(xmlhttp.readyState == 1) {
            document.getElementById('content').innerHTML = "<img src='loading.gif' />";
        }
        if(xmlhttp.readyState == 4 && xmlhttp.status == 200) {
          document.getElementById('content').innerHTML = xmlhttp.responseText;
        } 
      }

      xmlhttp.open('POST', x+'.html', true);
      xmlhttp.setRequestHeader('Content-type','application/x-www-form-urlencoded');
      xmlhttp.send(null);

    }

And in the HTML:

<body onload="showcontent(main)"> <!-- onload optional -->
<div id="content"><img src="loading.gif"></div> <!-- leave img out if not onload -->
</body>

I did something like that on my page and it works great.

Whenever I see addClass and removeClass I think why not just use toggleClass. In this case we can remove the .clickable class to avoid event bubbling, and to avoid the event from being fired on everything we click inside of the .clickable div.

$(document).on("click", ".close_button", function () { 
    $(this).closest(".grown").toggleClass("spot grown clickable");
});  

$(document).on("click", ".clickable", function () {
    $(this).toggleClass("spot grown clickable");
}); 

I also recommend a parent wrapper for your .clickable divs instead of using the document. I am not sure how you are adding them dynamically so didn't want to assume your layout for you.

Happy Coding :)

There are four main alternatives. Both have their quirks, but Method 4 has many advantages from my view.

./script is a shell script starting by #!/usr/bin/php

Method 1: $argv

./script hello wo8844rld
// $argv[0] = "script", $argv[1] = "hello", $argv[2] = "wo8844rld"

?? Using $argv, the parameter order is critical.

Method 2: getopt()

./script -p7 -e3
// getopt("p::")["p"] = "7", getopt("e::")["e"] = "3"

It's hard to use in conjunction of $argv, because:

?? The parsing of options will end at the first non-option found, anything that follows is discarded.

?? Only 26 parameters as the alphabet.

Method 3: Bash Global variable

P9="xptdr" ./script
// getenv("P9") = "xptdr"
// $_SERVER["P9"] = "xptdr"

Those variables can be used by other programs running in the same shell.

They are blown when the shell is closed, but not when the PHP program is terminated. We can set them permanent in file ~/.bashrc!

Method 4: STDIN pipe and stream_get_contents()

Some piping examples:

Feed a string:

./script <<< "hello wo8844rld"
// stream_get_contents(STDIN) = "hello wo8844rld"

Feed a string using bash echo:

echo "hello wo8844rld" | ./script
// explode(" ",stream_get_contents(STDIN)) ...

Feed a file content:

./script < ~/folder/Special_params.txt
// explode("\n",stream_get_contents(STDIN)) ...

Feed an array of values:

./script <<< '["array entry","lol"]'
// var_dump( json_decode(trim(stream_get_contents(STDIN))) );

Feed JSON content from a file:

echo params.json | ./script
// json_decode(stream_get_contents(STDIN)) ...

It might work similarly to fread() or fgets(), by reading the STDIN.

Bash-Scripting Guide

A simpler solution would be to use sessionStorage, in this case:

var myVariable = "Hello World";

sessionStorage['myvariable'] = myVariable;

var readValue = sessionStorage['myvariable'];
console.log(readValue);

However, keep in mind that sessionStorage saves everything as a string, so when working with arrays / objects, you can use JSON to store them:

var myVariable = {a:[1,2,3,4], b:"some text"};

sessionStorage['myvariable'] = JSON.stringify(myVariable);
var readValue = JSON.parse(sessionStorage['myvariable']);

A page session lasts for as long as the browser is open and survives over page reloads and restores. Opening a page in a new tab or window will cause a new session to be initiated.

So, when you close the page / tab, the data is lost.

You're not the only person having problems with Python 2.6 and MySQL (http://blog.contriving.net/2009/03/04/using-python-26-mysql-on-windows-is-nearly-impossible/). Here's an explanation how it should run under Python 2.5 http://i.justrealized.com/2008/04/08/how-to-install-python-and-django-in-windows-vista/ Good luck

The following should suffice:

[^ ]

If you want to expand that to anything but white-space (line breaks, tabs, spaces, hard spaces):

[^\s]

or

\S  # Note this is a CAPITAL 'S'!

You can use the following command to clear out ALL variables. Be careful because it you cannot get your variables back.

rm(list=ls(all=TRUE))

I think you'd be interested in the H1 debate. It's a debate about whether to use the h1 element for the page's title or for the logo.

Personally I'd go with your first suggestion, something along these lines:

<div id="header">
    <a href="http://example.com/"><img src="images/logo.png" id="site-logo" alt="MyCorp" /></a>
</div>

<!-- or alternatively (with css in a stylesheet ofc-->
<div id="header">
    <div id="logo" style="background: url('logo.png'); display: block; 
        float: left; width: 100px; height: 50px;">
        <a href="#" style="display: block; height: 50px; width: 100px;">
            <span style="visibility: hidden;">Homepage</span>
        </a>
    </div>
    <!-- with css in a stylesheet: -->
    <div id="logo"><a href="#"><span>Homepage</span></a></div>
</div>


<div id="body">
    <h1>About Us</h1>
    <p>MyCorp has been dealing in narcotics for over nine-thousand years...</p>
</div>

Of course this depends on whether your design uses page titles but this is my stance on this issue.

Both of them increase the variable i by one. It's like saying i = i + 1. The difference is subtle. If you're using it in a loop like this, there's no difference:

for (int i = 0; i < 100; i++) {
}

for (int i = 0; i < 100; ++i) {
}

If you want to know the difference, look at this example:

int a = 0;
int b = a++; // b = 0; a = 1

a = 0;
b = ++a: // b = 1; a = 1

The idea is that ++a increments a and returns that value, while a++ returns a's value and then increments a.

You can implement a system that handles the type checks automatically, using a wrapper in your function.

With this approach, you can build a complete declarative type check system that will manage for you the type checks . If you are interested in taking a more in depth look at this concept, check the Functyped library

The following implementation illustrates the main idea, in a simplistic, but operative way :

/*_x000D_
 * checkType() : Test the type of the value. If succeds return true, _x000D_
 * if fails, throw an Error_x000D_
 */_x000D_

  // perform the appropiate test to the passed _x000D_
  // value according to the provided type_x000D_

    case Number : _x000D_
      if(typeof value === 'number') return true;_x000D_
      break;_x000D_
    default :_x000D_
      throw new Error(`TypeError : Unknown type provided in argument ${i+1}`);_x000D_
  }_x000D_
  // test didn't succeed , throw error_x000D_

function typedFunction( parameterTypes, func ){_x000D_
  // types definitions and function parameters _x000D_

If you have a for loop such as the one below.

Change @item.StartDate to @item.StartDate.Value.ToShortDateString()

This will remove the time just in case you can't annotate your property in the model like in my case.

<table>
  <tr>
   <th>Type</th>
   <th>Start Date</th>
  </tr>
    @foreach (var item in Model.TestList) {
      <tr>
        <td>@item.TypeName</td>
        <td>@item.StartDate.Value.ToShortDateString()</td>
      </tr>
      }
</table>

    //Example to define how to do :

    DataTable dt = new DataTable();   

    dt.Columns.Add("ID");
    dt.Columns.Add("FirstName");
    dt.Columns.Add("LastName");
    dt.Columns.Add("Address");
    dt.Columns.Add("City");
           //  The table structure is:
            //ID    FirstName   LastName    Address     City

       //Now we want to add a PhoneNo column after the LastName column. For this we use the                               
             //SetOrdinal function, as iin:
        dt.Columns.Add("PhoneNo").SetOrdinal(3);

            //3 is the position number and positions start from 0.`enter code here`

               //Now the table structure will be:
              // ID      FirstName   LastName    PhoneNo    Address     City

Rule of thumb: Use -a and -o inside square brackets, && and || outside.

It's important to understand the difference between shell syntax and the syntax of the [ command.

• && and || are shell operators. They are used to combine the results of two commands. Because they are shell syntax, they have special syntactical significance and cannot be used as arguments to commands.

• [ is not special syntax. It's actually a command with the name [, also known as test. Since [ is just a regular command, it uses -a and -o for its and and or operators. It can't use && and || because those are shell syntax that commands don't get to see.

But wait! Bash has a fancier test syntax in the form of [[ ]]. If you use double square brackets, you get access to things like regexes and wildcards. You can also use shell operators like &&, ||, <, and > freely inside the brackets because, unlike [, the double bracketed form is special shell syntax. Bash parses [[ itself so you can write things like [[ $foo == 5 && $bar == 6 ]].

I suggest you much easier and platform independent solution to the problem - wappalyzer for Google Chrome:

See here

Since there is an uncertainity in calling of finalize() method by JVM (not sure whether finalize() which is overridden would be executed or not), for study purposes the better way to observe what happens when finalize() is called, is to force the JVM to call garbage collection by command System.gc().

Specifically, finalize() is called when an object is no longer in use. But when we try to call it by creating new objects there is no certainty of its call. So for certainty we create a null object c which obviously has no future use, hence we see the object c's finalize call.

Example

class Car {

    int maxspeed;

    Car() {
        maxspeed = 70;
    }

    protected void finalize() {

    // Originally finalize method does nothing, but here we override finalize() saying it to print some stmt
    // Calling of finalize is uncertain. Difficult to observe so we force JVM to call it by System.gc(); GarbageCollection

        System.out.println("Called finalize method in class Car...");
    }
}

class Bike {

    int maxspeed;

    Bike() {
        maxspeed = 50;
    }

    protected void finalize() {
        System.out.println("Called finalize method in class Bike...");
    }
}

class Example {

    public static void main(String args[]) {
        Car c = new Car();
        c = null;    // if c weren`t null JVM wouldn't be certain it's cleared or not, null means has no future use or no longer in use hence clears it
        Bike b = new Bike();
        System.gc();    // should clear c, but not b
        for (b.maxspeed = 1; b.maxspeed <= 70; b.maxspeed++) {
            System.out.print("\t" + b.maxspeed);
            if (b.maxspeed > 50) {
                System.out.println("Over Speed. Pls slow down.");
            }
        }
    }
}

Output

    Called finalize method in class Car...

            60Over Speed. Pls slow down.
            61Over Speed. Pls slow down.
            62Over Speed. Pls slow down.
            63Over Speed. Pls slow down.
            64Over Speed. Pls slow down.
            65Over Speed. Pls slow down.
            66Over Speed. Pls slow down.
            67Over Speed. Pls slow down.
            68Over Speed. Pls slow down.
            69Over Speed. Pls slow down.
            70Over Speed. Pls slow down.

Note - Even after printing upto 70 and after which object b is not being used in the program, there is uncertainty that b is cleared or not by JVM since "Called finalize method in class Bike..." is not printed.

Here is a more complete answer with regard to InnoDB. It is a bit of a lengthy process, but can be worth the effort.

Keep in mind that /var/lib/mysql/ibdata1 is the busiest file in the InnoDB infrastructure. It normally houses six types of information:

• Table Data
• Table Indexes
• MVCC (Multiversioning Concurrency Control) Data
  • Rollback Segments
  • Undo Space
• Table Metadata (Data Dictionary)
• Double Write Buffer (background writing to prevent reliance on OS caching)
• Insert Buffer (managing changes to non-unique secondary indexes)
• See the Pictorial Representation of ibdata1

InnoDB Architecture

Many people create multiple ibdata files hoping for better disk-space management and performance, however that belief is mistaken.

Can I run OPTIMIZE TABLE ?

Unfortunately, running OPTIMIZE TABLE against an InnoDB table stored in the shared table-space file ibdata1 does two things:

• Makes the table’s data and indexes contiguous inside ibdata1
• Makes ibdata1 grow because the contiguous data and index pages are appended to ibdata1

You can however, segregate Table Data and Table Indexes from ibdata1 and manage them independently.

Can I run OPTIMIZE TABLE with innodb_file_per_table ?

Suppose you were to add innodb_file_per_table to /etc/my.cnf (my.ini). Can you then just run OPTIMIZE TABLE on all the InnoDB Tables?

Good News : When you run OPTIMIZE TABLE with innodb_file_per_table enabled, this will produce a .ibd file for that table. For example, if you have table mydb.mytable witha datadir of /var/lib/mysql, it will produce the following:

• /var/lib/mysql/mydb/mytable.frm
• /var/lib/mysql/mydb/mytable.ibd

The .ibd will contain the Data Pages and Index Pages for that table. Great.

Bad News : All you have done is extract the Data Pages and Index Pages of mydb.mytable from living in ibdata. The data dictionary entry for every table, including mydb.mytable, still remains in the data dictionary (See the Pictorial Representation of ibdata1). YOU CANNOT JUST SIMPLY DELETE ibdata1 AT THIS POINT !!! Please note that ibdata1 has not shrunk at all.

InnoDB Infrastructure Cleanup

To shrink ibdata1 once and for all you must do the following:

1. Dump (e.g., with mysqldump) all databases into a .sql text file (SQLData.sql is used below)

2. Drop all databases (except for mysql and information_schema) CAVEAT : As a precaution, please run this script to make absolutely sure you have all user grants in place:

   mkdir /var/lib/mysql_grants
   cp /var/lib/mysql/mysql/* /var/lib/mysql_grants/.
   chown -R mysql:mysql /var/lib/mysql_grants
   

3. Login to mysql and run SET GLOBAL innodb_fast_shutdown = 0; (This will completely flush all remaining transactional changes from ib_logfile0 and ib_logfile1)

4. Shutdown MySQL

5. Add the following lines to /etc/my.cnf (or my.ini on Windows)

   [mysqld]
   innodb_file_per_table
   innodb_flush_method=O_DIRECT
   innodb_log_file_size=1G
   innodb_buffer_pool_size=4G
   

   (Sidenote: Whatever your set for innodb_buffer_pool_size, make sure innodb_log_file_size is 25% of innodb_buffer_pool_size.

   Also: innodb_flush_method=O_DIRECT is not available on Windows)

6. Delete ibdata* and ib_logfile*, Optionally, you can remove all folders in /var/lib/mysql, except /var/lib/mysql/mysql.

7. Start MySQL (This will recreate ibdata1 [10MB by default] and ib_logfile0 and ib_logfile1 at 1G each).

8. Import SQLData.sql

Now, ibdata1 will still grow but only contain table metadata because each InnoDB table will exist outside of ibdata1. ibdata1 will no longer contain InnoDB data and indexes for other tables.

For example, suppose you have an InnoDB table named mydb.mytable. If you look in /var/lib/mysql/mydb, you will see two files representing the table:

• mytable.frm (Storage Engine Header)
• mytable.ibd (Table Data and Indexes)

With the innodb_file_per_table option in /etc/my.cnf, you can run OPTIMIZE TABLE mydb.mytable and the file /var/lib/mysql/mydb/mytable.ibd will actually shrink.

I have done this many times in my career as a MySQL DBA. In fact, the first time I did this, I shrank a 50GB ibdata1 file down to only 500MB!

Give it a try. If you have further questions on this, just ask. Trust me; this will work in the short term as well as over the long haul.

CAVEAT

At Step 6, if mysql cannot restart because of the mysql schema begin dropped, look back at Step 2. You made the physical copy of the mysql schema. You can restore it as follows:

mkdir /var/lib/mysql/mysql
cp /var/lib/mysql_grants/* /var/lib/mysql/mysql
chown -R mysql:mysql /var/lib/mysql/mysql

Go back to Step 6 and continue

UPDATE 2013-06-04 11:13 EDT

With regard to setting innodb_log_file_size to 25% of innodb_buffer_pool_size in Step 5, that's blanket rule is rather old school.

Back on July 03, 2006, Percona had a nice article why to choose a proper innodb_log_file_size. Later, on Nov 21, 2008, Percona followed up with another article on how to calculate the proper size based on peak workload keeping one hour's worth of changes.

I have since written posts in the DBA StackExchange about calculating the log size and where I referenced those two Percona articles.

• Aug 27, 2012 : Proper tuning for 30GB InnoDB table on server with 48GB RAM
• Jan 17, 2013 : MySQL 5.5 - Innodb - innodb_log_file_size higher than 4GB combined?

Personally, I would still go with the 25% rule for an initial setup. Then, as the workload can more accurate be determined over time in production, you could resize the logs during a maintenance cycle in just minutes.

Here's a shorter version you can now use to turn the light on or off:

AVCaptureDevice *device = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];
if ([device hasTorch]) {
    [device lockForConfiguration:nil];
    [device setTorchMode:AVCaptureTorchModeOn];  // use AVCaptureTorchModeOff to turn off
    [device unlockForConfiguration];
}

UPDATE: (March 2015)

With iOS 6.0 and later, you can control the brightness or level of the torch using the following method:

- (void)setTorchToLevel:(float)torchLevel
{
    AVCaptureDevice *device = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];
    if ([device hasTorch]) {
        [device lockForConfiguration:nil];
        if (torchLevel <= 0.0) {
            [device setTorchMode:AVCaptureTorchModeOff];
        }
        else {
            if (torchLevel >= 1.0)
                torchLevel = AVCaptureMaxAvailableTorchLevel;
            BOOL success = [device setTorchModeOnWithLevel:torchLevel   error:nil];
        }
        [device unlockForConfiguration];
    }
}

You may also want to monitor the return value (success) from setTorchModeOnWithLevel:. You may get a failure if you try to set the level too high and the torch is overheating. In that case setting the level to AVCaptureMaxAvailableTorchLevel will set the level to the highest level that is allowed given the temperature of the torch.

The best and quick solution to the problem is first do this: View-> Show Symbol-> uncheck Show End of Line

This will solve problem for 90% of you and as in my case CR LF and its combinations still persist in the code. To fix this simply create a new tab using ctrl+n and copy whole file and paste in this new file. All CRLF gone, copy whole file again and go to original file delete whole code and paste the copied save and you rock!!!

Hope this helps.

What is a lambda function?

The C++ concept of a lambda function originates in the lambda calculus and functional programming. A lambda is an unnamed function that is useful (in actual programming, not theory) for short snippets of code that are impossible to reuse and are not worth naming.

In C++ a lambda function is defined like this

[]() { } // barebone lambda

or in all its glory

[]() mutable -> T { } // T is the return type, still lacking throw()

[] is the capture list, () the argument list and {} the function body.

The capture list

The capture list defines what from the outside of the lambda should be available inside the function body and how. It can be either:

1. a value: [x]
2. a reference [&x]
3. any variable currently in scope by reference [&]
4. same as 3, but by value [=]

You can mix any of the above in a comma separated list [x, &y].

The argument list

The argument list is the same as in any other C++ function.

The function body

The code that will be executed when the lambda is actually called.

Return type deduction

If a lambda has only one return statement, the return type can be omitted and has the implicit type of decltype(return_statement).

Mutable

If a lambda is marked mutable (e.g. []() mutable { }) it is allowed to mutate the values that have been captured by value.

Use cases

The library defined by the ISO standard benefits heavily from lambdas and raises the usability several bars as now users don't have to clutter their code with small functors in some accessible scope.

C++14

In C++14 lambdas have been extended by various proposals.

Initialized Lambda Captures

An element of the capture list can now be initialized with =. This allows renaming of variables and to capture by moving. An example taken from the standard:

int x = 4;
auto y = [&r = x, x = x+1]()->int {
            r += 2;
            return x+2;
         }();  // Updates ::x to 6, and initializes y to 7.

and one taken from Wikipedia showing how to capture with std::move:

auto ptr = std::make_unique<int>(10); // See below for std::make_unique
auto lambda = [ptr = std::move(ptr)] {return *ptr;};

Generic Lambdas

Lambdas can now be generic (auto would be equivalent to T here if T were a type template argument somewhere in the surrounding scope):

auto lambda = [](auto x, auto y) {return x + y;};

Improved Return Type Deduction

C++14 allows deduced return types for every function and does not restrict it to functions of the form return expression;. This is also extended to lambdas.

i have same issue with Amazon server i change my code to this

var connection = mysql.createConnection({

The current answers are a bit confusing and misleading, and they are missing some important DNS implications. I'll try to summarize where things stand clearly.

1. Generally speaking most IDisposable objects should ideally be disposed when you are done with them, especially those that own Named/shared OS resources. HttpClient is no exception, since as Darrel Miller points out it allocates cancellation tokens, and request/response bodies can be unmanaged streams.
2. However, the best practice for HttpClient says you should create one instance and reuse it as much as possible (using its thread-safe members in multi-threaded scenarios). Therefore, in most scenarios you'll never dispose of it simply because you will be needing it all the time.
3. The problem with re-using the same HttpClient "forever" is that the underlying HTTP connection might remain open against the originally DNS-resolved IP, regardless of DNS changes. This can be an issue in scenarios like blue/green deployment and DNS-based failover. There are various approaches for dealing with this issue, the most reliable one involving the server sending out a Connection:close header after DNS changes take place. Another possibility involves recycling the HttpClient on the client side, either periodically or via some mechanism that learns about the DNS change. See https://github.com/dotnet/corefx/issues/11224 for more information (I suggest reading it carefully before blindly using the code suggested in the linked blog post).

After long search and hours of trying this is the simplest code i could make:

ShapeDrawable border = new ShapeDrawable(new RectShape());
border.getPaint().setStyle(Style.STROKE);
border.getPaint().setColor(Color.BLACK);
tv.setBackground(border);
content.addView(tv);

tv is a TextView with a simple text and content is my container (LinearLayout in this Case). That's a little easier.

public static boolean compareList(List ls1, List ls2){
    return ls1.containsAll(ls2) && ls1.size() == ls2.size() ? true :false;
     }

public static void main(String[] args) {

    ArrayList<String> one = new ArrayList<String>();
    one.add("one");
    one.add("two");
    one.add("six");

    ArrayList<String> two = new ArrayList<String>();
    two.add("one");
    two.add("six");
    two.add("two");

    System.out.println("Output1 :: " + compareList(one, two));

    two.add("ten");

    System.out.println("Output2 :: " + compareList(one, two));
  }

It's as simple as:

>>> lists = [[1, 2], [3, 4]]
>>> np.array(lists)
array([[1, 2],
       [3, 4]])

I have written this article about the ICommand interface.

The idea - creating a universal command that takes two delegates: one is called when ICommand.Execute (object param) is invoked, the second checks the status of whether you can execute the command (ICommand.CanExecute (object param)).

Requires the method to switching event CanExecuteChanged. It is called from the user interface elements for switching the state CanExecute() command.

public class ModelCommand : ICommand
{
    #region Constructors

    public ModelCommand(Action<object> execute)
        : this(execute, null) { }

    public ModelCommand(Action<object> execute, Predicate<object> canExecute)
    {
        _execute = execute;
        _canExecute = canExecute;
    }

    #endregion

    #region ICommand Members

    public event EventHandler CanExecuteChanged;

    public bool CanExecute(object parameter)
    {
        return _canExecute != null ? _canExecute(parameter) : true;
    }

    public void Execute(object parameter)
    {
        if (_execute != null)
            _execute(parameter);
    }

    public void OnCanExecuteChanged()
    {
        CanExecuteChanged(this, EventArgs.Empty);
    }

    #endregion

    private readonly Action<object> _execute = null;
    private readonly Predicate<object> _canExecute = null;
}

I've created a dynamic way to call each event automatically. It perfect to focus a field, because it call the event just once, removing it after use.

function modalEvents() {
    var modal = $('#modal');
    var events = ['show', 'shown', 'hide', 'hidden'];

    $(events).each(function (index, event) {
        modal.on(event + '.bs.modal', function (e) {
            var callback = modal.data(event + '-callback');
            if (typeof callback != 'undefined') {
                callback.call();
                modal.removeData(event + '-callback');
            }
        });
    });
}

You just need to call modalEvents() on document ready.

Use:

$('#modal').data('show-callback', function() {
    $("input#photo_name").focus();
});

So, you can use the same modal to load what you want without worry about remove events every time.

The space before the = is interpreted as part of the name, and the space after it (as well as the quotation marks) are interpreted as part of the value. So the variable you’ve created can be referenced with %location %. If that’s not what you want, remove the extra space(s) in the definition.

if you set your context model as code first based on exist database so you have to for set migration:

Add-Migration InitialCreate –IgnoreChanges
Update-database -force

and then change your context model and set:

Add-migration RemoveIspositive
Update-database -force

The last N added records, from less recent to most recent, can be seen with this query:

db.collection.find().skip(db.collection.count() - N)

If you want them in the reverse order:

db.collection.find().sort({ $natural: -1 }).limit(N)

If you install Mongo-Hacker you can also use:

db.collection.find().reverse().limit(N)

If you get tired of writing these commands all the time you can create custom functions in your ~/.mongorc.js. E.g.

function last(N) {
    return db.collection.find().skip(db.collection.count() - N);
}

then from a mongo shell just type last(N)

You haven't included package declarations in the OP but it is possible that neither @SpringBootApplication nor @ComponentScan are scanning for your @Component.

The @ComponentScan Javadoc states:

Either basePackageClasses or basePackages (or its alias value) may be specified to define specific packages to scan. If specific packages are not defined, scanning will occur from the package of the class that declares this annotation.

ISTR wasting a lot of time on this before and found it easiest to simply move my application class to the highest package in my app's package tree.

More recently I encountered a gotcha were the property was being read before the value insertion had been done. Jesse's answer helped as @PostConstruct seems to be the earliest you can read the inserted values, and of course you should let Spring call this.

One way, everyone already have written in thier answers:

driver.manage().window().maximize() 

but if you looking for alternative ways, here you are:

driver.manage().window().setSize(screenResolution);

or

driver.findElement(By.id("......")).sendKeys(Keys.F11);

Craig Stuntz has written an extensive (in my opinion) blog post on troubleshooting this exact error message, I personally would start there.

The following res: (resource) references need to point to your model.

<add name="Entities" connectionString="metadata=
    res://*/Models.WraithNath.co.uk.csdl|
    res://*/Models.WraithNath.co.uk.ssdl|
    res://*/Models.WraithNath.co.uk.msl;

Make sure each one has the name of your .edmx file after the "*/", with the "edmx" changed to the extension for that res (.csdl, .ssdl, or .msl).

It also may help to specify the assembly rather than using "//*/".

Worst case, you can check everything (a bit slower but should always find the resource) by using

<add name="Entities" connectionString="metadata=
        res://*/;provider= <!-- ... -->

In any case you can know it:

Easiest method:

From Command Line, use:

for %f in (*.*) do echo %f

From a Batch File (double up the % percent signs):

for %%f in (*.*) do echo %%f

From a Batch File with folder specified as 1st parameter:

for %%f in (%1\*.*) do echo %%f

Something throws an exception of type std::bad_alloc, indicating that you ran out of memory. This exception is propagated through until main, where it "falls off" your program and causes the error message you see.

Since nobody here knows what "RectInvoice", "rectInvoiceVector", "vect", "im" and so on are, we cannot tell you what exactly causes the out-of-memory condition. You didn't even post your real code, because w h looks like a syntax error.

Make sure any XML file (or any file that would be interpreted as an XML file by visual studio) has a correct XML structure - that is, one root element (with any name, I have use rootElement in my example):

<?xml version="1.0"?> 
<rootElement>
 ...
</rootElement>

Two options:

Do the division after the multiplication:

int n = 25;
int v = 100;
int percent = n * 100 / v;

Convert an int to a float before dividing

int n = 25;
int v = 100;
float percent = n * 100f / v;
//Or:
//  float percent = (float) n * 100 / v;
//  float percent = n * 100 / (float) v;

@Jason S: your "fmod" variant will not work on a standards-compliant implementation. The C standard is explicit and clear (7.12.10.1, "the fmod functions"):

if y is nonzero, the result has the same sign as x

thus,

fmod(atan2(y,x)/M_PI*180,360)

is actually just a verbose rewriting of:

atan2(y,x)/M_PI*180

Your third suggestion, however, is spot on.

This line of code might not work in IE 8 because of native support problems.

$(".hidden").attr("placeholder", "Type here to search");

You can try importing a JQuery placeholder plugin for this task. Simply import it to your libraries and initiate from the sample code below.

$('input, textarea').placeholder();

Tag ids must be unique. You are updating the span with ID 'ItemCostSpan' of which there are two. Give the span a class and get it using find.

    $("legend").each(function() {
        var SoftwareItem = $(this).text();
        itemCost = GetItemCost(SoftwareItem);
        $("input:checked").each(function() {               
            var Component = $(this).next("label").text();
            itemCost += GetItemCost(Component);
        });            
        $(this).find(".ItemCostSpan").text("Item Cost = $ " + itemCost);
    });

I ran into this issue when I was referencing

 [drive]:\Program Files\Java\jdk1.8.0_65 

in my JAVA_HOME environment var instead of the Android Studio recommended

[drive]:\Program Files\Java\jdk1.7.0_79. 

I am using the x64 version of the JDK on Windows 10 Pro.

From the Android Studio installation instructions.

Before you set up Android Studio, be sure you have installed JDK 6 or higher (the JRE alone is not sufficient)—JDK 7 is required when developing for Android 5.0 and higher. To check if you have JDK installed (and which version), open a terminal and type javac -version. If the JDK is not available or the version is lower than version 6, download the Java SE Development Kit 7

http://developer.android.com/sdk/installing/index.html?pkg=studio

Include an Setup Project (New Project > Other Project Types > Setup and Deployment > Visual Studio Installer) in your solution. It has options to include the framework installer. Check out this Deployment Guide MSDN post.

Possible reasons are 1. you didn't load React.JS into your page, 2. you loaded it after the above script into your page. Solution is load the JS file before the above shown script.

P.S

Possible solutions.

1. If you mention react in externals section inside webpack configuration, then you must load react js files directly into your html before bundle.js
2. Make sure you have the line import React from 'react';

The pip wheel contains the python version in its name (cp34-cp34m). If you download the whl file and rename it to say py3-none or instead, it should work. Can you try that?

The installation won't work for anaconda users that choose python 3 support because the installation procedure is asking to create a python 3.5 environment and the file is currently called cp34-cp34m. So renaming it would do the job for now.

sudo pip3 install --upgrade https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow-0.7.0-cp34-cp34m-linux_x86_64.whl

This will produced the exact error message you got above. However, when you will downloaded the file yourself and rename it to "tensorflow-0.7.0-py3-none-linux_x86_64.whl", then execute the command again with changed filename, it should work fine.

Try this:

You need to stop iterating once you know a number isn't prime. Add a break once you find prime to exit the while loop.

Making only minimal changes to your code to make it work:

a=2
num=13
while num > a :
  if num%a==0 & a!=num:
    print('not prime')
    break
  i += 1
else: # loop not exited via break
  print('prime')

Your algorithm is equivalent to:

for a in range(a, num):
    if a % num == 0:
        print('not prime')
        break
else: # loop not exited via break
    print('prime')

If you throw it into a function you can dispense with break and for-else:

def is_prime(n):
    for i in range(3, n):
        if n % i == 0:
            return False
    return True

Even if you are going to brute-force for prime like this you only need to iterate up to the square root of n. Also, you can skip testing the even numbers after two.

With these suggestions:

import math
def is_prime(n):
    if n % 2 == 0 and n > 2: 
        return False
    for i in range(3, int(math.sqrt(n)) + 1, 2):
        if n % i == 0:
            return False
    return True

Note that this code does not properly handle 0, 1, and negative numbers.

We make this simpler by using all with a generator expression to replace the for-loop.

import math
def is_prime(n):
    if n % 2 == 0 and n > 2: 
        return False
    return all(n % i for i in range(3, int(math.sqrt(n)) + 1, 2))

I believe you need to specify "Option Infer On" for this to work.

Option Infer allows the compiler to make a guess at what is being represented by your code, thus it will guess that {"stuff"} is an array of strings. With "Option Infer Off", {"stuff"} won't have any type assigned to it, ever, and so it will always fail, without a type specifier.

Option Infer is, I think On by default in new projects, but Off by default when you migrate from earlier frameworks up to 3.5.

Opinion incoming:

Also, you mention that you've got "Option Explicit Off". Please don't do this.

Setting "Option Explicit Off" means that you don't ever have to declare variables. This means that the following code will silently and invisibly create the variable "Y":

Dim X as Integer
Y = 3

This is horrible, mad, and wrong. It creates variables when you make typos. I keep hoping that they'll remove it from the language.

Used below code to set driver type based on need of Headless / Head for both Firefox and chrome:

// Can pass browser type 

if brower.lower() == 'chrome':
    driver = webdriver.Chrome('..\drivers\chromedriver')
elif brower.lower() == 'headless chrome':
    ch_Options = Options()
    ch_Options.add_argument('--headless')
    ch_Options.add_argument("--disable-gpu")
    driver = webdriver.Chrome('..\drivers\chromedriver',options=ch_Options)
elif brower.lower() == 'firefox':
    driver = webdriver.Firefox(executable_path=r'..\drivers\geckodriver.exe')
elif brower.lower() == 'headless firefox':
    ff_option = FFOption()
    ff_option.add_argument('--headless')
    ff_option.add_argument("--disable-gpu")
    driver = webdriver.Firefox(executable_path=r'..\drivers\geckodriver.exe', options=ff_option)
elif brower.lower() == 'ie':
    driver = webdriver.Ie('..\drivers\IEDriverServer')
else:
    raise Exception('Invalid Browser Type')

You can use Boolean / boolean. Simplicity is the way to go. If you do not need specific api (Collections, Streams, etc.) and you are not foreseeing that you will need them - use primitive version of it (boolean).

1. With primitives you guarantee that you will not pass null values.
   You will not fall in traps like this. The code below throws NullPointerException (from: Booleans, conditional operators and autoboxing):

   public static void main(String[] args) throws Exception { Boolean b = true ? returnsNull() : false; // NPE on this line. System.out.println(b); } public static Boolean returnsNull() { return null; }

2. Use Boolean when you need an object, eg:

   • Stream of Booleans,
   • Optional
   • Collections of Booleans

read it in the docs. If you return anything but an int or None it will be printed to stderr.

To get just stderr while discarding stdout do:

output=$(python foo.py 2>&1 >/dev/null)
