Just a wild guess: (not much to go on) but I have had similar problems when, for example, I was using the IIS rewrite module on my local machine (and it worked fine), but when I uploaded to a host that did not have that add-on module installed, I would get a 500 error with very little to go on - sounds similar. It drove me crazy trying to find it.
So make sure whatever options/addons that you might have and be using locally in IIS are also installed on the host.
Similarly, make sure you understand everything that is being referenced/used in your web.config - that is likely the problem area.
If you are using Spring as Back-End server and especially using Spring Security then i found a solution by putting http.cors();
in the configure
method. The method looks like that:
protected void configure(HttpSecurity http) throws Exception {
http
.csrf().disable()
.authorizeRequests() // authorize
.anyRequest().authenticated() // all requests are authenticated
.and()
.httpBasic();
http.cors();
}
To get rid of error:
Type '"text"' is not assignable to type '"json"'.
Use
responseType: 'text' as 'json'
import { HttpClient, HttpHeaders } from '@angular/common/http';
.....
return this.http
.post<string>(
this.baseUrl + '/Tickets/getTicket',
JSON.stringify(value),
{ headers, responseType: 'text' as 'json' }
)
.map(res => {
return res;
})
.catch(this.handleError);
There are two possible reasons 1. If you are using HttpClient in your service you need to import HttpClientModule in your module file and mention it in the imports array.
import { HttpClientModule } from '@angular/common/http';
If you are using normal Http in your services you need to import HttpModule in your module file and mention it in the imports array.
import { HttpModule } from '@angular/http
'
By default, this is not available in the angular then you need to install @angular/http
If you wish you can use both HttpClientModule and HttpModule in your project.
Got this from a network filter (LuLu on macOS) blocking traffic to/from Docker-related processes.
If this isn't a good solution for any reason, please let me know. It worked fine for me.
What I did is to hide the Sidebar and then make appear the navbar with breakpoints
@media screen and (max-width: 771px) {
#fixed-sidebar {
display: none;
}
#navbar-superior {
display: block !important;
}
}
The following worked for me after hours of trying
$http.post("http://localhost:8080/yourresource", parameter, {headers:
{'Content-Type': 'application/json', 'Access-Control-Allow-Origin': '*' } }).
However following code did not work, I am unclear as to why, hopefully someone can improve this answer.
$http({ method: 'POST', url: "http://localhost:8080/yourresource",
parameter,
headers: {'Content-Type': 'application/json',
'Access-Control-Allow-Origin': '*',
'Access-Control-Allow-Methods': 'POST'}
})
Don't need to use this method:
.map((res: Response) => res.json() );
Just use this simple method instead of the previous method. hopefully you'll get your result:
.map(res => res );
Upgrade to React Native 0.58.5 or higher version.
They have includeSubdomain
in their config files in RN 0.58.5.
In Rn 0.58.5 they have declared network_security_config
with their server domain. Network security configuration allows an app to permit cleartext traffic from a certain domain. So no need to put extra effort by declaring android:usesCleartextTraffic="true"
in the application tag of your manifest file. It will be resolved automatically after upgrading the RN Version.
To add multiples params or headers you can do the following:
constructor(private _http: HttpClient) {}
//....
const url = `${environment.APP_API}/api/request`;
let headers = new HttpHeaders().set('header1', hvalue1); // create header object
headers = headers.append('header2', hvalue2); // add a new header, creating a new object
headers = headers.append('header3', hvalue3); // add another header
let params = new HttpParams().set('param1', value1); // create params object
params = params.append('param2', value2); // add a new param, creating a new object
params = params.append('param3', value3); // add another param
return this._http.get<any[]>(url, { headers: headers, params: params })
While the accepted answer solved the OP's original problem, most people finding this question through a Google search are likely having an entirely different problem which just happens to throw the same no suitable HttpMessageConverter found exception.
What happens under the covers is that MappingJackson2HttpMessageConverter
swallows any exceptions that occur in its canRead()
method, which is supposed to auto-detect whether the payload is suitable for json decoding. The exception is replaced by a simple boolean return that basically communicates sorry, I don't know how to decode this message to the higher level APIs (RestClient
). Only after all other converters' canRead() methods return false, the no suitable HttpMessageConverter found exception is thrown by the higher-level API, totally obscuring the true problem.
For people who have not found the root cause (like you and me, but not the OP), the way to troubleshoot this problem is to place a debugger breakpoint on onMappingJackson2HttpMessageConverter.canRead()
, then enable a general breakpoint on any exception, and hit Continue. The next exception is the true root cause.
My specific error happened to be that one of the beans referenced an interface that was missing the proper deserialization annotations.
UPDATE FROM THE FUTURE
This has proven to be such a recurring issue across so many of my projects, that I've developed a more proactive solution. Whenever I have a need to process JSON exclusively (no XML or other formats), I now replace my RestTemplate
bean with an instance of the following:
public class JsonRestTemplate extends RestTemplate {
public JsonRestTemplate(
ClientHttpRequestFactory clientHttpRequestFactory) {
super(clientHttpRequestFactory);
// Force a sensible JSON mapper.
// Customize as needed for your project's definition of "sensible":
ObjectMapper objectMapper = new ObjectMapper()
.registerModule(new Jdk8Module())
.registerModule(new JavaTimeModule())
.configure(
SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);
List<HttpMessageConverter<?>> messageConverters = new ArrayList<>();
MappingJackson2HttpMessageConverter jsonMessageConverter = new MappingJackson2HttpMessageConverter() {
public boolean canRead(java.lang.Class<?> clazz,
org.springframework.http.MediaType mediaType) {
return true;
}
public boolean canRead(java.lang.reflect.Type type,
java.lang.Class<?> contextClass,
org.springframework.http.MediaType mediaType) {
return true;
}
protected boolean canRead(
org.springframework.http.MediaType mediaType) {
return true;
}
};
jsonMessageConverter.setObjectMapper(objectMapper);
messageConverters.add(jsonMessageConverter);
super.setMessageConverters(messageConverters);
}
}
This customization makes the RestClient
incapable of understanding anything other than JSON. The upside is that any error messages that may occur will be much more explicit about what's wrong.
It's not recommended but you can access to database on main thread with allowMainThreadQueries()
MyApp.database = Room.databaseBuilder(this, AppDatabase::class.java, "MyDatabase").allowMainThreadQueries().build()
Gmail tends to block usage of mailing addresses which are being used in other applications as username for security reasons. Either you should create a new email address for mail purpose or you must go to the Less Secure App Access and turn on the access for less secure apps. Gmail will send you a mail for confirmation from where you can verify that those changes were made by yourself. Only then, you can use such mailing addresses for mailing purpose through applications.

I also have this issue and have been looking into it for a long time. It seems that there is no such problem on python 3+. The problem is actually on google.protobuf
pip uninstall protobuf
pip uninstall google
pip install google
pip install protobuf
pip install google-cloud
create an __init__.py
in "google" folder.
cd /path/to/your/env/lib/python2.7/site-packages/google
touch __init__.py
Hopefully it will work.
This is what worked for me. Issue is earlier I didn't set Content Type(header) when I used exchange method.
MultiValueMap<String, String> map = new LinkedMultiValueMap<String, String>();
map.add("param1", "123");
map.add("param2", "456");
map.add("param3", "789");
map.add("param4", "123");
map.add("param5", "456");
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
final HttpEntity<MultiValueMap<String, String>> entity = new HttpEntity<MultiValueMap<String, String>>(map ,
headers);
JSONObject jsonObject = null;
try {
RestTemplate restTemplate = new RestTemplate();
ResponseEntity<String> responseEntity = restTemplate.exchange(
"https://url", HttpMethod.POST, entity,
String.class);
if (responseEntity.getStatusCode() == HttpStatus.CREATED) {
try {
jsonObject = new JSONObject(responseEntity.getBody());
} catch (JSONException e) {
throw new RuntimeException("JSONException occurred");
}
}
} catch (final HttpClientErrorException httpClientErrorException) {
throw new ExternalCallBadRequestException();
} catch (HttpServerErrorException httpServerErrorException) {
throw new ExternalCallServerErrorException(httpServerErrorException);
} catch (Exception exception) {
throw new ExternalCallServerErrorException(exception);
}
ExternalCallBadRequestException and ExternalCallServerErrorException are the custom exceptions here.
Note: Remember HttpClientErrorException is thrown when a 4xx error is received. So if the request you send is wrong either setting header or sending wrong data, you could receive this exception.
Note: I had truncated the first part of the FCM token (before :
) and the error was MismatchSenderId
Fixed my script and now everything works fine.
Cross origin protection is a feature of the browser. Curl does not care for CORS, as you presumed. That explains why your curls are successful, while the browser requests are not.
If you send the browser request with the wrong credentials, spring will try to forward the client to a login page. This response (off the login page) does not contain the header 'Access-Control-Allow-Origin' and the browser reacts as you describe.
You must make spring to include the haeder for this login response, and may be for other response, like error pages etc.
This can be done like this :
@Configuration
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/api/**")
.allowedOrigins("http://domain2.com")
.allowedMethods("PUT", "DELETE")
.allowedHeaders("header1", "header2", "header3")
.exposedHeaders("header1", "header2")
.allowCredentials(false).maxAge(3600);
}
}
This is copied from cors-support-in-spring-framework
I would start by adding cors mapping for all resources with :
registry.addMapping("/**")
and also allowing all methods headers.. Once it works you may start to reduce that again to the needed minimum.
Please note, that the CORS configuration changes with Release 4.2.
If this does not solve your issues, post the response you get from the failed ajax request.
You simply need to add that line legend: { display: false }
Since HttpClient
use SendAsync
method to perform all HTTP Requests
, you can override SendAsync
method and mock the HttpClient
.
For that wrap creating HttpClient
to a interface
, something like below
public interface IServiceHelper
{
HttpClient GetClient();
}
Then use above interface
for dependency injection in your service, sample below
public class SampleService
{
private readonly IServiceHelper serviceHelper;
public SampleService(IServiceHelper serviceHelper)
{
this.serviceHelper = serviceHelper;
}
public async Task<HttpResponseMessage> Get(int dummyParam)
{
try
{
var dummyUrl = "http://www.dummyurl.com/api/controller/" + dummyParam;
var client = serviceHelper.GetClient();
HttpResponseMessage response = await client.GetAsync(dummyUrl);
return response;
}
catch (Exception)
{
// log.
throw;
}
}
}
Now in unit test project create a helper class for mocking SendAsync
.
Here it is a FakeHttpResponseHandler
class which is inheriting
DelegatingHandler
which will provide an option to override the SendAsync
method. After overriding the SendAsync
method need to setup a response for each HTTP Request
which is calling SendAsync
method, for that create a Dictionary
with key
as Uri
and value
as HttpResponseMessage
so that whenever there is a HTTP Request
and if the Uri
matches SendAsync
will return the configured HttpResponseMessage
.
public class FakeHttpResponseHandler : DelegatingHandler
{
private readonly IDictionary<Uri, HttpResponseMessage> fakeServiceResponse;
private readonly JavaScriptSerializer javaScriptSerializer;
public FakeHttpResponseHandler()
{
fakeServiceResponse = new Dictionary<Uri, HttpResponseMessage>();
javaScriptSerializer = new JavaScriptSerializer();
}
/// <summary>
/// Used for adding fake httpResponseMessage for the httpClient operation.
/// </summary>
/// <typeparam name="TQueryStringParameter"> query string parameter </typeparam>
/// <param name="uri">Service end point URL.</param>
/// <param name="httpResponseMessage"> Response expected when the service called.</param>
public void AddFakeServiceResponse(Uri uri, HttpResponseMessage httpResponseMessage)
{
fakeServiceResponse.Remove(uri);
fakeServiceResponse.Add(uri, httpResponseMessage);
}
/// <summary>
/// Used for adding fake httpResponseMessage for the httpClient operation having query string parameter.
/// </summary>
/// <typeparam name="TQueryStringParameter"> query string parameter </typeparam>
/// <param name="uri">Service end point URL.</param>
/// <param name="httpResponseMessage"> Response expected when the service called.</param>
/// <param name="requestParameter">Query string parameter.</param>
public void AddFakeServiceResponse<TQueryStringParameter>(Uri uri, HttpResponseMessage httpResponseMessage, TQueryStringParameter requestParameter)
{
var serilizedQueryStringParameter = javaScriptSerializer.Serialize(requestParameter);
var actualUri = new Uri(string.Concat(uri, serilizedQueryStringParameter));
fakeServiceResponse.Remove(actualUri);
fakeServiceResponse.Add(actualUri, httpResponseMessage);
}
// all method in HttpClient call use SendAsync method internally so we are overriding that method here.
protected override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
{
if(fakeServiceResponse.ContainsKey(request.RequestUri))
{
return Task.FromResult(fakeServiceResponse[request.RequestUri]);
}
return Task.FromResult(new HttpResponseMessage(HttpStatusCode.NotFound)
{
RequestMessage = request,
Content = new StringContent("Not matching fake found")
});
}
}
Create a new implementation for IServiceHelper
by mocking framework or like below.
This FakeServiceHelper
class we can use to inject the FakeHttpResponseHandler
class so that whenever the HttpClient
created by this class
it will use FakeHttpResponseHandler class
instead of the actual implementation.
public class FakeServiceHelper : IServiceHelper
{
private readonly DelegatingHandler delegatingHandler;
public FakeServiceHelper(DelegatingHandler delegatingHandler)
{
this.delegatingHandler = delegatingHandler;
}
public HttpClient GetClient()
{
return new HttpClient(delegatingHandler);
}
}
And in test configure FakeHttpResponseHandler class
by adding the Uri
and expected HttpResponseMessage
.
The Uri
should be the actual service
endpoint Uri
so that when the overridden SendAsync
method is called from actual service
implementation it will match the Uri
in Dictionary
and respond with the configured HttpResponseMessage
.
After configuring inject the FakeHttpResponseHandler object
to the fake IServiceHelper
implementation.
Then inject the FakeServiceHelper class
to the actual service which will make the actual service to use the override SendAsync
method.
[TestClass]
public class SampleServiceTest
{
private FakeHttpResponseHandler fakeHttpResponseHandler;
[TestInitialize]
public void Initialize()
{
fakeHttpResponseHandler = new FakeHttpResponseHandler();
}
[TestMethod]
public async Task GetMethodShouldReturnFakeResponse()
{
Uri uri = new Uri("http://www.dummyurl.com/api/controller/");
const int dummyParam = 123456;
const string expectdBody = "Expected Response";
var expectedHttpResponseMessage = new HttpResponseMessage(HttpStatusCode.OK)
{
Content = new StringContent(expectdBody)
};
fakeHttpResponseHandler.AddFakeServiceResponse(uri, expectedHttpResponseMessage, dummyParam);
var fakeServiceHelper = new FakeServiceHelper(fakeHttpResponseHandler);
var sut = new SampleService(fakeServiceHelper);
var response = await sut.Get(dummyParam);
var responseBody = await response.Content.ReadAsStringAsync();
Assert.AreEqual(HttpStatusCode.OK, response.StatusCode);
Assert.AreEqual(expectdBody, responseBody);
}
}
Finally found the simplest way:
<button (click)="toggle($event)" class="someclass" id="btn1"></button>
<button (click)="toggle($event)" class="someclass" id="btn2"></button>
toggle(event) {
console.log(event.target.id);
}

My issue was simple when i faced the following error:
objects are not valid as a react child (found object with keys {...}
was just that I was passing an object with keys specified in the error while trying to render the object directly in a component using {object} expecting it to be a string
object: {
key1: "key1",
key2: "key2"
}
while rendering on a React Component, I used something like below
render() {
return this.props.object;
}
but it should have been
render() {
return this.props.object.key1;
}
I have solved as plist file.
Add a NSAppTransportSecurity : Dictionary.
Add Subkey named " NSAllowsArbitraryLoads " as Boolean : YES
Add a "User-Agent" header to your request.
Some servers attempt to block spidering programs and scrapers from accessing their server because, in earlier days, requests did not send a user agent header.
You can either try to set a custom user agent value or use some value that identifies a Browser like "Mozilla/5.0 Firefox/26.0"
RestTemplate restTemplate = new RestTemplate();
HttpHeaders headers = new HttpHeaders();
headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
headers.setContentType(MediaType.APPLICATION_JSON);
headers.add("user-agent", "Mozilla/5.0 Firefox/26.0");
headers.set("user-key", "your-password-123"); // optional - in case you auth in headers
HttpEntity<String> entity = new HttpEntity<String>("parameters", headers);
ResponseEntity<Game[]> respEntity = restTemplate.exchange(url, HttpMethod.GET, entity, Game[].class);
logger.info(respEntity.toString());
Evaluating the error response from another service invocated...
This was my solution for evaluating the error:
try {
return authenticationFeign.signIn(userDto, dataRequest);
}catch(FeignException ex){
//ex.status();
if(ex.status() == HttpStatus.UNAUTHORIZED.value()){
System.out.println("is a error 401");
return new ResponseEntity<>(HttpStatus.UNAUTHORIZED);
}
return new ResponseEntity<>(HttpStatus.OK);
}
Try this,
// prepare json data
let json: [String: Any] = ["title": "ABC",
"dict": ["1":"First", "2":"Second"]]
let jsonData = try? JSONSerialization.data(withJSONObject: json)
// create post request
let url = URL(string: "http://httpbin.org/post")!
var request = URLRequest(url: url)
request.httpMethod = "POST"
// insert json data to the request
request.httpBody = jsonData
let task = URLSession.shared.dataTask(with: request) { data, response, error in
guard let data = data, error == nil else {
print(error?.localizedDescription ?? "No data")
return
}
let responseJSON = try? JSONSerialization.jsonObject(with: data, options: [])
if let responseJSON = responseJSON as? [String: Any] {
print(responseJSON)
}
}
task.resume()
or try a convenient way Alamofire
I removed the following files from the ~/.android folder:
I disabled and enabled ADB within device and now it works...
None of the other answers worked for me. The solution that worked for me was to download the missing artifact manually via cmd:
mvn dependency:get -DrepoUrl=http://repo.maven.apache.org/maven2/ -Dartifact=ro.isdc.wro4j:wro4j-maven-plugin:1.8.0
These are good answers but detached from a full answer as to how you would get a form to send data and handle that response. This will demonstrate how to add a member to a list with v3.0 of the API from an HTML page via jquery .ajax()
.
In Mailchimp:
zipcode
as a custom field in the list BEFORE I did the API call.create
method which requires the use of HTTP POST
requests. There are other options in here that require PUT
if you want to be able to modify/delete subs.HTML:
<form id="pfb-signup-submission" method="post">
<div class="sign-up-group">
<input type="text" name="pfb-signup" id="pfb-signup-box-fname" class="pfb-signup-box" placeholder="First Name">
<input type="text" name="pfb-signup" id="pfb-signup-box-lname" class="pfb-signup-box" placeholder="Last Name">
<input type="email" name="pfb-signup" id="pfb-signup-box-email" class="pfb-signup-box" placeholder="[email protected]">
<input type="text" name="pfb-signup" id="pfb-signup-box-zip" class="pfb-signup-box" placeholder="Zip Code">
</div>
<input type="submit" class="submit-button" value="Sign-up" id="pfb-signup-button"></a>
<div id="pfb-signup-result"></div>
</form>
Key things:
<form>
a unique ID and don't forget the method="post"
attribute so the form works. #signup-result
is where you will deposit the feedback from the PHP script.PHP:

* Typical use case is that this code would get run by an .ajax() jQuery call or possibly a form action
* The live data you need will get transferred via the global $_POST variable
* That data must be put into an array with keys that match the mailchimp endpoints, check the above link for those

Key things:
CURLOPT_USERPWD
handles the API key and Mailchimp doesn't really show you how to do this. CURLOPT_RETURNTRANSFER
gives us the response in such a way that we can send it back into the HTML page with the .ajax()
success
handler.json_encode
on the data you received.JS:
// Signup form submission
$('#pfb-signup-submission').submit(function(event) {
event.preventDefault();
// Get data from form and store it
var pfbSignupFNAME = $('#pfb-signup-box-fname').val();
var pfbSignupLNAME = $('#pfb-signup-box-lname').val();
var pfbSignupEMAIL = $('#pfb-signup-box-email').val();
var pfbSignupZIP = $('#pfb-signup-box-zip').val();
// Create JSON variable of retreived data
var pfbSignupData = {
'firstname': pfbSignupFNAME,
'lastname': pfbSignupLNAME,
'email': pfbSignupEMAIL,
'zipcode': pfbSignupZIP
};
// Send data to PHP script via .ajax() of jQuery
$.ajax({
type: 'POST',
dataType: 'json',
url: 'mailchimp-signup.php',
data: pfbSignupData,
success: function (results) {
$('#pfb-signup-box-fname').hide();
$('#pfb-signup-box-lname').hide();
$('#pfb-signup-box-email').hide();
$('#pfb-signup-box-zip').hide();
$('#pfb-signup-result').text('Thanks for adding yourself to the email list. We will be in touch.');
console.log(results);
},
error: function (results) {
$('#pfb-signup-result').html('<p>Sorry but we were unable to add you into the email list.</p>');
console.log(results);
}
});
});
Key things:
JSON
data is VERY touchy on transfer. Here, I am putting it into an array and it looks easy. If you are having problems, it is likely because of how your JSON data is structured. Check this out!_POST
global variable. In this case it will be _POST['email']
, _POST['firstname']
, etc. But you could name them whatever you want - just remember what you name the keys of the data
part of your JSON transfer is how you access them in PHP.Replace:
$authorization = "Bearer 080042cad6356ad5dc0a720c18b53b8e53d4c274"
with:
$authorization = "Authorization: Bearer 080042cad6356ad5dc0a720c18b53b8e53d4c274";
to make it a valid and working Authorization header.

driver.find_element_by_tag_name('body').send_keys(Keys.CONTROL + Keys.TAB)
driver.quit()
I think this is better solution so far.
The error that you get does not seem to be related to the RequestHeader.
And you seem to be confusing Spring REST services with JAX-RS, your method signature should be something like:
@RequestMapping(produces = "application/json", method = RequestMethod.GET, value = "data")
@ResponseBody
public ResponseEntity<Data> getData(@RequestHeader(value="User-Agent") String userAgent, @RequestParam(value = "ID", defaultValue = "") String id) {
// your code goes here
}
And your REST class should have annotations like:
@Controller
@RequestMapping("/rest/")
Regarding the actual question, another way to get HTTP headers is to insert the HttpServletRequest into your method and then get the desired header from there.
Example:
@RequestMapping(produces = "application/json", method = RequestMethod.GET, value = "data")
@ResponseBody
public ResponseEntity<Data> getData(HttpServletRequest request, @RequestParam(value = "ID", defaultValue = "") String id) {
String userAgent = request.getHeader("user-agent");
}
Don't worry about the injection of the HttpServletRequest because Spring does that magic for you ;)
Use ng-pattern, in this example you can validate a simple patern with 10 numbers, when the patern is not matched ,the message is show and the button is disabled.
<form name="phoneNumber">
<label for="numCell" class="text-strong">Phone number</label>
<input id="numCell" type="text" name="inputCelular" ng-model="phoneNumber"
class="form-control" required ng-pattern="/^[0-9]{10,10}$/"></input>
<div class="alert-warning" ng-show="phoneNumber.inputCelular.$error.pattern">
<p> write a phone number</p>
</div>
<button id="button" class="btn btn-success" click-once ng-disabled="!phoneNumber.$valid" ng-click="callDigitaliza()">Buscar</button>
Also you can use another complex patern like
^+?\d{1,3}?[- .]?(?(?:\d{2,3}))?[- .]?\d\d\d[- .]?\d\d\d\d$
, for more complex phone numbers
The exception occurs due to this statement,
called_from.equalsIgnoreCase("add")
It seem that the previous statement
String called_from = getIntent().getStringExtra("called");
returned a null reference.
You can check whether the intent to start this activity contains such a key "called".
@KyleMit answer is one way to solve this, however we may chose to avoid the undivided input fields acheived by input-group
class. A better way to do this is by using form-group
and row
classes on a parent div
and use input
elements with grid-system classes provided by bootstrap.
<div class="form-group row">
<input class="form-control col-md-6" type="text">
<input class="form-control col-md-6" type="text">
</div>
A correct file upload would like this:
HTTP header:
Content-Type: multipart/form-data; boundary=ABCDEFGHIJKLMNOPQ
Http body:
--ABCDEFGHIJKLMNOPQ
Content-Disposition: form-data; name="file"; filename="my.txt"
Content-Type: application/octet-stream
Content-Length: ...
<...file data in base 64...>
--ABCDEFGHIJKLMNOPQ--
and code is like this:
public void uploadFile(File file) {
try {
RestTemplate restTemplate = new RestTemplate();
String url = "http://localhost:8080/file/user/upload";
HttpMethod requestMethod = HttpMethod.POST;
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.MULTIPART_FORM_DATA);
MultiValueMap<String, String> fileMap = new LinkedMultiValueMap<>();
ContentDisposition contentDisposition = ContentDisposition
.builder("form-data")
.name("file")
.filename(file.getName())
.build();
fileMap.add(HttpHeaders.CONTENT_DISPOSITION, contentDisposition.toString());
HttpEntity<byte[]> fileEntity = new HttpEntity<>(Files.readAllBytes(file.toPath()), fileMap);
MultiValueMap<String, Object> body = new LinkedMultiValueMap<>();
body.add("file", fileEntity);
HttpEntity<MultiValueMap<String, Object>> requestEntity = new HttpEntity<>(body, headers);
ResponseEntity<String> response = restTemplate.exchange(url, requestMethod, requestEntity, String.class);
System.out.println("file upload status code: " + response.getStatusCode());
} catch (IOException e) {
e.printStackTrace();
}
}
All your problems are that you are mixing content type negotiation with parameter passing. They are things at different levels. More specific, for your question 2, you constructed the response header with the media type your want to return. The actual content negotiation is based on the accept media type in your request header, not response header. At the point the execution reaches the implementation of the method getPersonFormat, I am not sure whether the content negotiation has been done or not. Depends on the implementation. If not and you want to make the thing work, you can overwrite the request header accept type with what you want to return.
return new ResponseEntity<>(PersonFactory.createPerson(), httpHeaders, HttpStatus.OK);
ResponseEntity
is meant to represent the entire HTTP response. You can control anything that goes into it: status code, headers, and body.
@ResponseBody
is a marker for the HTTP response body and @ResponseStatus
declares the status code of the HTTP response.
@ResponseStatus
isn't very flexible. It marks the entire method so you have to be sure that your handler method will always behave the same way. And you still can't set the headers. You'd need the HttpServletResponse
or a HttpHeaders
parameter.
Basically, ResponseEntity
lets you do more.
@RequestMapping(value="/add/image", method=RequestMethod.POST)
public ResponseEntity upload(@RequestParam("id") Long id, HttpServletResponse response, HttpServletRequest request)
{
try {
MultipartHttpServletRequest multipartRequest=(MultipartHttpServletRequest)request;
Iterator<String> it=multipartRequest.getFileNames();
MultipartFile multipart=multipartRequest.getFile(it.next());
String fileName=id+".png";
String imageName = fileName;
byte[] bytes=multipart.getBytes();
BufferedOutputStream stream= new BufferedOutputStream(new FileOutputStream("src/main/resources/static/image/book/"+fileName));;
stream.write(bytes);
stream.close();
return new ResponseEntity("upload success", HttpStatus.OK);
} catch (Exception e) {
e.printStackTrace();
return new ResponseEntity("Upload fialed", HttpStatus.BAD_REQUEST);
}
}
curl is a command in linux (and a library in php). Curl typically makes an HTTP request.
What you really want to do is make an HTTP (or XHR) request from javascript.
Using this vocab you'll find a bunch of examples, for starters: Sending authorization headers with jquery and ajax
Essentially you will want to call $.ajax
with a few options for the header, etc.
$.ajax({
url: 'https://api.wit.ai/message?v=20140826&q=',
beforeSend: function(xhr) {
xhr.setRequestHeader("Authorization", "Bearer 6QXNMEMFHNY4FJ5ELNFMP5KRW52WFXN5")
}, success: function(data){
alert(data);
//process the JSON data etc
}
})
This could be achieve with the below mentioned psuedo code approach
Import os import requests Data = os.execute(curl URL) R= Data.json()
For Hibernate you can use the jackson-datatype-hibernate project to accommodate JSON serialization/deserialization with lazy-loaded objects.
For example,
import com.fasterxml.jackson.databind.Module;
import com.fasterxml.jackson.datatype.hibernate5.Hibernate5Module;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class JacksonDatatypeHibernate5Configuration {
// Register Jackson Hibernate5 Module to handle JSON serialization of lazy-loaded entities
// Any beans of type com.fasterxml.jackson.databind.Module are automatically
// registered with the auto-configured Jackson2ObjectMapperBuilder
// https://docs.spring.io/spring-boot/docs/current/reference/html/howto-spring-mvc.html#howto-customize-the-jackson-objectmapper
@Bean
public Module hibernate5Module() {
Hibernate5Module hibernate5Module = new Hibernate5Module();
hibernate5Module.enable( Hibernate5Module.Feature.FORCE_LAZY_LOADING );
hibernate5Module.disable( Hibernate5Module.Feature.USE_TRANSIENT_ANNOTATION );
return hibernate5Module;
}
}
//create authentication base 64 encoding string

//let base64EncodedCredential = PasswordData!.base64EncodedStringWithOptions(nil)

let queue:NSOperationQueue = NSOperationQueue()
let urlConnection = NSURLConnection(request: request, delegate: self)
urlConnection.start()
//2 URL Request with AsynchronousRequest
NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue.mainQueue()) {(response, data, error) in
println(NSString(data: data, encoding: NSUTF8StringEncoding))
}
//2 URL Request with AsynchronousRequest with json output
NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue.mainQueue(), completionHandler:{ (response: NSURLResponse!, data: NSData!, error: NSError!) -> Void in

// you may be get fatal error if you changed the request.HTTPMethod = "POST" when server request GET request
Without you providing any specific error message, it's hard to give specific suggestions.
However, I was using the same example and was getting a permissions exception on File.OpenWrite - using the localFileName variable, because using Path.GetFile was pointing to a location that obviously would not have permissions for opening a file > C:\ProgramFiles\IIS(Express)\filename.doc
I found that using System.IO.Path.GetFileName is not correct, use System.IO.Path.GetFullPath instead, point to your file starting with "C:\..."
Also open your solution in FileExplorer and grant permissions to asp.net for the file or any folders holding the file. I was able to download my file at that point.
Instead:
public class PhotosFragment extends Fragment
You can use:
public class PhotosFragment extends ListFragment
It change the methods
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
ArrayList<ListviewContactItem> listContact = GetlistContact();
setAdapter(new ListviewContactAdapter(getActivity(), listContact));
}
onActivityCreated is void and you didn't need to return a view like in onCreateView
You can see an example here
In case anyone had the same problem: check this as @PravinS suggested. I used the exact same code as shown there and it worked for me perfectly.
This is the relevant part of the server code that helped:
if (isset($_POST['btnUpload']))
{
$url = "URL_PATH of upload.php"; // e.g. http://localhost/myuploader/upload.php // request URL
$filename = $_FILES['file']['name'];
$filedata = $_FILES['file']['tmp_name'];
$filesize = $_FILES['file']['size'];
if ($filedata != '')
{
$headers = array("Content-Type:multipart/form-data"); // cURL headers for file uploading
$postfields = array("filedata" => "@$filedata", "filename" => $filename);
$ch = curl_init();
$options = array(
CURLOPT_URL => $url,
CURLOPT_HEADER => true,
CURLOPT_POST => 1,
CURLOPT_HTTPHEADER => $headers,
CURLOPT_POSTFIELDS => $postfields,
CURLOPT_INFILESIZE => $filesize,
CURLOPT_RETURNTRANSFER => true
); // cURL options
curl_setopt_array($ch, $options);
curl_exec($ch);
if(!curl_errno($ch))
{
$info = curl_getinfo($ch);
if ($info['http_code'] == 200)
$errmsg = "File uploaded successfully";
}
else
{
$errmsg = curl_error($ch);
}
curl_close($ch);
}
else
{
$errmsg = "Please select the file";
}
}
html form should look something like:
<form action="uploadpost.php" method="post" name="frmUpload" enctype="multipart/form-data">
<tr>

<td align="center">:</td>
<td><input name="file" type="file" id="file"/></td>
</tr>
<tr>
<td> </td>
<td align="center"> </td>
<td><input name="btnUpload" type="submit" value="Upload" /></td>
</tr>

Hibernate queries are case sensitive with property names (because they end up relying on getter/setter methods on the @Entity
).
Make sure you refer to the property as fileName
in the Criteria query, not filename
.
Specifically, Hibernate will call the getter method of the filename
property when executing that Criteria query, so it will look for a method called getFilename()
. But the property is called FileName
and the getter getFileName()
.
So, change the projection like so:
criteria.setProjection(Projections.property("fileName"));
You opened a lot of connections and that's the issue. I think in your code, you did not close the opened connection.
A database bounce could temporarily solve, but will re-appear when you do consecutive execution. Also, it should be verified the number of concurrent connections to the database. If maximum DB processes parameter has been reached this is a common symptom.
Courtesy of this thread: https://community.oracle.com/thread/362226?tstart=-1
Most likely the headers you are setting is incorrect or not acceptable.
Example: connnection.setRequestProperty("content-type", "application/json");
As mentioned in the comments to the question, the JDBC-ODBC Bridge is - as the name indicates - only a mechanism for the JDBC layer to "talk to" the ODBC layer. Even if you had a JDBC-ODBC Bridge on your Mac you would also need to have
So, for most people, using JDBC-ODBC Bridge technology to manipulate ACE/Jet ("Access") databases is really a practical option only under Windows. It is also important to note that the JDBC-ODBC Bridge will be has been removed in Java 8 (ref: here).
There are other ways of manipulating ACE/Jet databases from Java, such as UCanAccess and Jackcess. Both of these are pure Java implementations so they work on non-Windows platforms. For details on how to use UCanAccess see
I have an extension method:
public static string GetIp(this HttpContextBase context)
{
if (context == null || context.Request == null)
return string.Empty;
return context.Request.ServerVariables["HTTP_X_FORWARDED_FOR"]
?? context.Request.UserHostAddress;
}
Note: "HTTP_X_FORWARDED_FOR" is for ip behind proxy. context.Request.UserHostAddress is identical to "REMOTE_ADDR".
But bear in mind it is not necessary the actual IP though.
Sources:
You have empty $_POST
. If your web-server wants see data in json-format you need to read the raw input and then parse it with JSON decode.
You need something like that:
$json = file_get_contents('php://input');
$obj = json_decode($json);
Also you have wrong code for testing JSON-communication...
CURLOPT_POSTFIELDS
tells curl
to encode your parameters as application/x-www-form-urlencoded
. You need JSON-string here.
UPDATE
Your php code for test page should be like that:
$data_string = json_encode($data);
$ch = curl_init('http://webservice.local/');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($data_string))
);
$result = curl_exec($ch);
$result = json_decode($result);
var_dump($result);
Also on your web-service page you should remove one of the lines header('Content-type: application/json');
. It must be called only once.
In case of NULL
columns it is better to use IF
clause like this which combine the two functions of : CONCAT
and COALESCE
and uses special chars between the columns in result like space or '_'
SELECT FirstName , LastName ,
IF(FirstName IS NULL AND LastName IS NULL, NULL,' _ ',CONCAT(COALESCE(FirstName ,''), COALESCE(LastName ,'')))

It looks like the phoneGap plugin will allow you to get the device's uid.
http://docs.phonegap.com/en/3.0.0/cordova_device_device.md.html#device.uuid
Update: This is dependent on running native code. We used this solution writing javascript that was being compiled to native code for a native phone application we were creating.
Check this one. It will work.
function fetch($i1,$i2,$i3,$i4)
{
$input_data = '<I>
<i1>'.$i1.'</i1>
<i2>'.$i2.'</i2>
<i3>'.$i2.'</i3>
<i4>'.$i3.'</i4>
</I>';
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_PORT => "8080",
CURLOPT_URL => "http://192.168.1.100:8080/avaliablity",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "POST",
CURLOPT_POSTFIELDS => $input_data,
CURLOPT_HTTPHEADER => array(
"Cache-Control: no-cache",
"Content-Type: application/xml"
),
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
echo "cURL Error #:" . $err;
} else {
echo $response;
}
}
fetch('i1','i2','i3','i4');
Sometimes using row.getLastCellNum()
gives you a higher value than what is actually filled in the file.
I used the method below to get the last column index that contains an actual value.
private int getLastFilledCellPosition(Row row) {
int columnIndex = -1;
for (int i = row.getLastCellNum() - 1; i >= 0; i--) {
Cell cell = row.getCell(i);
if (cell == null || CellType.BLANK.equals(cell.getCellType()) || StringUtils.isBlank(cell.getStringCellValue())) {
continue;
} else {
columnIndex = cell.getColumnIndex();
break;
}
}
return columnIndex;
}
It also works if you change the content type
<form method="POST"
action="http://localhost:8080/cms/customer/create_customer"
id="frmRegister" name="frmRegister"
enctype="application/x-www-form-urlencoded">
In the controller also add the header value as follows:
@RequestMapping(value = "/create_customer", method = RequestMethod.POST, headers = "Content-Type=application/x-www-form-urlencoded")
window.location.reload() // without passing true as argument
works for me.
If you add this to your web.config transformation file, you can also set certain publish options to have debugging enabled or disabled:
<system.web>
<customErrors mode="Off" defaultRedirect="~/Error.aspx" xdt:Transform="Replace"/>
</system.web>
For those coming to this with similar problems, this request library allows you to make external http requests seemlessly within your php application. Simplified GET, POST, PATCH, DELETE and PUT requests.
A sample request would be as below
use Libraries\Request;
$data = [
'samplekey' => 'value',
'otherkey' => 'othervalue'
];
$headers = [
'Content-Type' => 'application/json',
'Content-Length' => sizeof($data)
];
$response = Request::post('https://example.com', $data, $headers);
// the $response variable contains response from the request
Documentation for the same can be found in the project's README.md
Try:
$result = curl_exec($cURL);
$result = json_decode($result,true);
Now you can access MessageID
from $result['MessageID']
.
As for the database, it's simply using a query like so:
INSERT INTO `tableName`(`Cancelled`,`Queued`,`SMSError`,`SMSIncommingMessage`,`Sent`,`SentDateTime`) VALUES('?','?','?','?','?');
Prepared.
I think the only cookie you need is JSESSIONID=xxx..
Also NEVER share your cookies, becasuse someone may access your personal data that way. Specially when the cookies are session. These cookies will stop working once you logout the site.
A repair of the DotNetCore hosting bundle did the trick for me. :/
The RestTemplate getForObject()
method does not support setting headers. The solution is to use the exchange()
method.
So instead of restTemplate.getForObject(url, String.class, param)
(which has no headers), use
HttpHeaders headers = new HttpHeaders();
headers.set("Header", "value");
headers.set("Other-Header", "othervalue");
...
HttpEntity entity = new HttpEntity(headers);
ResponseEntity<String> response = restTemplate.exchange(
url, HttpMethod.GET, entity, String.class, param);
Finally, use response.getBody()
to get your result.
This question is similar to this question.

Keep your code clean and stylesheets logically separated per screen 'media' type config...
1) Using himansu's answer from above as a reference: Common CSS Media Queries Break Points

I had the same issue. Running exec sp_updatestats
did work sometimes, but not always. I decided to use the NOLOCK
statement in my queries to speed up the queries.
Just add NOLOCK
after your FROM clause, e.g.:
SELECT clicks.entryURL, clicks.entryTime, sessions.userID
FROM sessions, clicks WITH (NOLOCK)
WHERE sessions.sessionID = clicks.sessionID AND clicks.entryTime > DATEADD(day, -1, GETDATE())
Read the full article here.
The following code describes a simple example using POST
method.(How one can pass data by POST
method)
Here, I describe how one can use of POST method.
1. Set post string with actual username and password.
NSString *post = [NSString stringWithFormat:@"Username=%@&Password=%@",@"username",@"password"];
2. Encode the post string using NSASCIIStringEncoding
and also the post string you need to send in NSData format.
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
You need to send the actual length of your data. Calculate the length of the post string.
NSString *postLength = [NSString stringWithFormat:@"%d",[postData length]];
3. Create a Urlrequest with all the properties like HTTP
method, http header field with length of the post string. Create URLRequest
object and initialize it.
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
Set the Url for which your going to send the data to that request.
[request setURL:[NSURL URLWithString:@"http://www.abcde.com/xyz/login.aspx"]];
Now, set HTTP method (POST or GET). Write this lines as it is in your code.
[request setHTTPMethod:@"POST"];
Set HTTP
header field with length of the post data.
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
Also set the Encoded value for HTTP header Field.
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
Set the HTTPBody
of the urlrequest with postData.
[request setHTTPBody:postData];
4. Now, create URLConnection object. Initialize it with the URLRequest.
NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:request delegate:self];
It returns the initialized url connection and begins to load the data for the url request. You can check that whether you URL
connection is done properly or not using just if/else statement as below.
if(conn) {
NSLog(@"Connection Successful");
} else {
NSLog(@"Connection could not be made");
}
5. To receive the data from the HTTP request , you can use the delegate methods provided by the URLConnection Class Reference. Delegate methods are as below.
// This method is used to receive the data which we get using post method.
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData*)data
// This method receives the error report in case of connection is not made to server.
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
// This method is used to process the data after connection has made successfully.
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
Also Refer This and This documentation for POST
method.
And here is best example with source code of HTTPPost Method.
In my case the issue was a missing 's' in the HTTP URL. Error was: "HttpHostConnectException: Connect to someendpoint.com:80 [someendpoint.com/127.0.0.1] failed: Connection refused" End point and IP obviously changed to protect the network.
I'm going to answer my own question.
Therefore, the following works for me
$qb->select('c')
->innerJoin('c.phones', 'p', 'WITH', 'p.phone = :phone')
->where('c.username = :username');
or
$qb->select('c')
->innerJoin('c.phones', 'p', Join::WITH, $qb->expr()->eq('p.phone', ':phone'))
->where('c.username = :username');
this code works with me
ImageView carView = (ImageView) v.findViewById(R.id.car_icon);
byte[] decodedString = Base64.decode(picture, Base64.NO_WRAP);
InputStream input=new ByteArrayInputStream(decodedString);
Bitmap ext_pic = BitmapFactory.decodeStream(input);
carView.setImageBitmap(ext_pic);
The best solution is a minimal use of java directly in the visualstudio GUI
here it is: On a button go to the "OnClientClick" property (its not into events*) overthere type:
return confirm('are you sure?')
it will put a dialog with cancel ok buttons transparent over current page if cancel is pressed no postback will ocure. However if you want only ok button type:
alert ('i told you so')
The events like onclick work server side they execute your code, while OnClientClick runs in the browser side. the come most close to a basic dialog

I had to solve a similar problem--I wanted certain styles to only apply to mobile devices in landscape mode. Essentially the fonts and line spacing looked fine in every other context, so I just needed the one exception for mobile landscape. This media query worked perfectly:

}
Would this work better?

The above host is already occupied by the emulator in which you are running the code. If you want to access the local host of your computer than use the IP Address as http://10.0.2.2:8080/

If you are sending anything other than simple strings I would recommend using a POST with an appropriate request body, or passing the entire list as an appropriately encoded JSON string. However, with simple strings you just need to append each value to the request URL appropriately and Jersey will deserialize it for you. So given the following example endpoint:
@Path("/service/echo") public class MyServiceImpl {
public MyServiceImpl() {
super();
}
@GET
@Path("/withlist")
@Produces(MediaType.TEXT_PLAIN)
public Response echoInputList(@QueryParam("list") final List<String> inputList) {
return Response.ok(inputList).build();
}
}
Your client would send a request corresponding to:
GET http://example.com/services/echo?list=Hello&list=Stay&list=Goodbye
Which would result in inputList
being deserialized to contain the values 'Hello', 'Stay' and 'Goodbye'
With CSS3 we can easily adjust an image. But remember this does not change the image. It only displays the adjusted image.
See the following code for more details.
To make an image gray:
img {
-webkit-filter: grayscale(100%);
}
To give a sepia look:
img {
-webkit-filter: sepia(100%);
}
To adjust brightness:
img {
-webkit-filter: brightness(50%);
}
To adjust contrast:
img {
-webkit-filter: contrast(200%);
}
To Blur an image:
img {
-webkit-filter: blur(10px);
}
You should also do it for different browser. That is include all css statements
filter: grayscale(100%);
-webkit-filter: grayscale(100%);
-moz-filter: grayscale(100%);
To use multiple
filter: blur(5px) grayscale(1);

Had to debug a site for native Android browser and came here. So I tried weinre on an OS X 10.9 (as weinre server) with Firefox 30.0 (weinre client) and an Android 4.1.2 (target). I'm really, really surprised of the result.
sudo npm -g install weinre
weinre --boundHost YOUR.IP.ADDRESS.HERE
http://YOUR.IP.ADRESS.HERE:8080
<script src="http://YOUR.IP.ADDRESS.HERE:8080/target/target-script-min.js"></script>
Maybe 8080 isn't your default port. Then in step 4 you have to call weinre --httpPort YOURPORT --boundHost YOUR.IP.ADRESS.HERE
.
And I don't remember exactly when it was, maybe somewhere after step 5, I had to accept incoming connections prompt, of course.
Happy debugging
P.S. I'm still overwhelmed how good that works. Even elements-highlighting work
I had the same problem and the "Microsoft.Web.Infrastructure.dll" appeared to be missing. I have tried few advises and installed MVC`s etc. and nothing helped.

But in my case only this way could help:
1. Make backup of current DB
2. Drop DB (not all tables, but DB)
3. Create DB (check that you still have previleges)
4. Restore DB from backup
You have most of the code…
CURLOPT_HTTPHEADER
for curl_setopt()
takes an array with each header as an element. You have one element with multiple headers.
You also need to add the Authorization header to your $header
array.
$header = array();
$header[] = 'Content-length: 0';
$header[] = 'Content-type: application/json';
$header[] = 'Authorization: OAuth SomeHugeOAuthaccess_tokenThatIReceivedAsAString';
I had the same problem. To fix it in Jboss 7 AS, I copy the oracle driver jar file to Jboss module folder. Example: ../jboss-as-7.1.1.Final/modules/org/hibernate/main

I am trying to fetch record from database first and store in ArrayList but when i return array list on html page it display only last record repeatedly as count of my database table
This part has mostly been covered by all the previous answers. So you would need to create a new instance of your CustomerDTO
within your while
loop and add it to your ArrayList
.
There's one more thing that I wanted to comment about:
Statement
or your Connection
objects (not so sure if you're pooling your connection, in that case you would need to release this connection to the pool)So, when you consider these points, the structure of your code might look something like this:
public ArrayList<CustomerDTO> getAllCustomers()
{
ArrayList<CustomerDTO> customers = new ArrayList<CustomerDTO>();
Connection c = null;
Statement statement = null;
ResultSet rs = null;
try {
c = openConnection();
statement = c.createStatement();
String s = "SELECT * FROM customer";
rs = statement.executeQuery(s);
int g =0;
while (rs.next()) {
CustomerDTO customer = new CustomerDTO();
//Code to fill up your DTO
customers.add(customer);
}
} catch (Exception e) {
System.out.println(e);
}finally{
//Code to release your resources
}
return customers;
}
If you have not too much data, you can definitely do pagination by just storing all the data in the browser and filtering what's visible at a certain time.
Here's a simple pagination example: http://jsfiddle.net/2ZzZB/56/
That example was on the list of fiddles on the angular.js github wiki, which should be helpful: https://github.com/angular/angular.js/wiki/JsFiddle-Examples

Short version: Create styles only once, use them everywhere.
Long version: use a method to create the styles you need (beware of the limit on the amount of styles).
private static Map<String, CellStyle> styles;
private static Map<String, CellStyle> createStyles(Workbook wb){
Map<String, CellStyle> styles = new HashMap<String, CellStyle>();
DataFormat df = wb.createDataFormat();
CellStyle style;
Font headerFont = wb.createFont();
headerFont.setBoldweight(Font.BOLDWEIGHT_BOLD);
headerFont.setFontHeightInPoints((short) 12);
style = createBorderedStyle(wb);
style.setAlignment(CellStyle.ALIGN_CENTER);
style.setFont(headerFont);
styles.put("style1", style);
style = createBorderedStyle(wb);
style.setAlignment(CellStyle.ALIGN_CENTER);
style.setFillForegroundColor(IndexedColors.LIGHT_CORNFLOWER_BLUE.getIndex());
style.setFillPattern(CellStyle.SOLID_FOREGROUND);
style.setFont(headerFont);
style.setDataFormat(df.getFormat("d-mmm"));
styles.put("date_style", style);
...
return styles;
}
you can also use methods to do repetitive tasks while creating styles hashmap
private static CellStyle createBorderedStyle(Workbook wb) {
CellStyle style = wb.createCellStyle();
style.setBorderRight(CellStyle.BORDER_THIN);
style.setRightBorderColor(IndexedColors.BLACK.getIndex());
style.setBorderBottom(CellStyle.BORDER_THIN);
style.setBottomBorderColor(IndexedColors.BLACK.getIndex());
style.setBorderLeft(CellStyle.BORDER_THIN);
style.setLeftBorderColor(IndexedColors.BLACK.getIndex());
style.setBorderTop(CellStyle.BORDER_THIN);
style.setTopBorderColor(IndexedColors.BLACK.getIndex());
return style;
}
then, in your "main" code, set the style from the styles map you have.
Cell cell = xssfCurrentRow.createCell( intCellPosition );
cell.setCellValue( blah );
cell.setCellStyle( (CellStyle) styles.get("style1") );
Try like this:
$url = 'url_to_post';
// this is only part of the data you need to sen
$customer_data = array("first_name" => "First name","last_name" => "last name","email"=>"[email protected]","addresses" => array ("address1" => "some address" ,"city" => "city","country" => "CA", "first_name" => "Mother","last_name" => "Lastnameson","phone" => "555-1212", "province" => "ON", "zip" => "123 ABC" ) );
// As per your API, the customer data should be structured this way
$data = array("customer" => $customer_data);
// And then encoded as a json string
$data_string = json_encode($data);
$ch=curl_init($url);
curl_setopt_array($ch, array(
CURLOPT_POST => true,
CURLOPT_POSTFIELDS => $data_string,
CURLOPT_HEADER => true,
CURLOPT_HTTPHEADER => array('Content-Type:application/json', 'Content-Length: ' . strlen($data_string)))
));
$result = curl_exec($ch);
curl_close($ch);
The key thing you've forgotten was to json_encode your data. But you also may find it convenient to use curl_setopt_array to set all curl options at once by passing an array.
The original answer is that your path has to join prefix like Uri.parse("file://" + file.getPath);
Slightly different approach:
MultiValueMap<String, String> headers = new LinkedMultiValueMap<String, String>();
headers.add("HeaderName", "value");
headers.add("Content-Type", "application/json");
RestTemplate restTemplate = new RestTemplate();
restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
HttpEntity<ObjectToPass> request = new HttpEntity<ObjectToPass>(objectToPass, headers);
restTemplate.postForObject(url, request, ClassWhateverYourControllerReturns.class);
We had the same issue, in making a websocket connection to the Load Balancer. The issue is in LB, accepting http connection on port 80 and forwarding the request to node (tomcat app on port 8080). We have changed this to accept tcp (http has been changed as 'tcp') connection on port 80. So the first handshake request is forwarded to Node and a websocket connection is made successfully on some random( as far as i know, may be wrong) port.
below command has been used to test the websocket handshake process.
curl -v -i -N -H "Connection: Upgrade" -H "Upgrade: websocket" -H "Host: localhost" -H "Origin: http://LB URL:80" http://LB URL
GET / HTTP/1.1 Host: localhost User-Agent: curl/7.60.0 Accept: / Connection: Upgrade Upgrade: websocket Origin: http://LB URL:80

According to the docs: http://web.archive.org/web/20170909233829/https://source.android.com/devices/tech/dalvik/configure an .odex
file:
contains AOT compiled code for methods in the APK.
Furthermore, they appear to be regular shared libraries, since if you get any app, and check:
file /data/app/com.android.appname-*/oat/arm64/base.odex
it says:
base.odex: ELF shared object, 64-bit LSB arm64, stripped
and aarch64-linux-gnu-objdump -d base.odex
seems to work and give some meaningful disassembly (but also some rubbish sections).
I just came across a similar problem. Try
require './st.rb'
This should do the trick.
For a hyperlink just use www.facebook.com/++page ID++/like
Eg: www.facebook.com/MYPAGEISAWESOME/like
To make it work with m.facebook.com
here's what you do:
Open the Facebook page you're looking for then change the URL to the mobile URL ( which is www.m.facebook.com/MYPAGEISAWESOME
).
Now you should see a big version of the mobile Facebook page. Copy the target URL of the like button.
Pop that URL into the QR generator to make a "scan to like" barcode. This will open the m.Facebook
page in the browser of most mobiles directly from the QR reader. If they are not logged into Facebook then they will be prompted to log in and then click 'like'. If logged in, it will auto like.
Hope this helps!
Also, definitely include something with a "click here/scan here to like us on Facebook"
As you have mentioned it doesn't change anything.
First, you should redirect both standard input and standard error from the crontab execution like below:
*/2 * * * * /usr/bin/python /home/souza/Documets/Listener/listener.py > /tmp/listener.log 2>&1
Then you can view the file /tmp/listener.log
to see if the script executed as you expected.
Second, I guess what you mean by change anything is by watching the files created by your program:
f = file('counter', 'r+w')
json_file = file('json_file_create_server.json', 'r+w')
The crontab job above won't create these file in directory /home/souza/Documets/Listener
, as the cron job is not executed in this directory, and you use relative path in the program. So to create this file in directory /home/souza/Documets/Listener
, the following cron job will do the trick:
*/2 * * * * cd /home/souza/Documets/Listener && /usr/bin/python listener.py > /tmp/listener.log 2>&1
Change to the working directory and execute the script from there, and then you can view the files created in place.
Android needs to be compiled for every hardware plattform / every device model seperatly with the specific drivers etc. If you manage to do that you need also break the security arrangements every manufacturer implements to prevent the installation of other software - these are also different between each model / manufacturer. So it is possible at in theory, but only there :-)
con = new SqlConnection(@"Data Source=.\SQLEXPRESS;AttachDbFilename=C:\Users\Yna Maningding-Dula\Documents\Visual Studio 2010\Projects\LuxuryHotel\LuxuryHotel\ClientsRecords.mdf;Integrated Security=True;User Instance=True");

I was attempting something similar, and the RoboSpice example helped me work it out:
HttpHeaders headers = new HttpHeaders();
headers.set("Accept", "application/json");
HttpEntity<String> request = new HttpEntity<>(input, createHeader());
String url = "http://awesomesite.org";
Uri.Builder uriBuilder = Uri.parse(url).buildUpon();
uriBuilder.appendQueryParameter(key, value);
uriBuilder.appendQueryParameter(key, value);
...
String url = uriBuilder.build().toString();
HttpEntity<String> response = restTemplate.exchange(url, HttpMethod.GET, request , String.class);
Yes, you could make an indexer on your Record class that maps from the property name to the correct property. This would keep all the binding from property name to property in one place eg:
public class Record
{
public string ItemType { get; set; }
public string this[string propertyName]
{
set
{
switch (propertyName)
{
case "itemType":
ItemType = value;
break;
// etc
}
}
}
}
Alternatively, as others have mentioned, use reflection.
?? Wrong Nuget Package Version ??
I had a unit test project which was pulling in our companies internal EF Nuget data access package and that code pulled in an external package whose version was way behind the current version.
The issue was that the Nuget settings for the package was set to the least version
; and the older version won and was used during operations....
Hence it silently got the wrong version for a common assembly used by both the package and the app.
Solution
By Setting/updating the package in Nuget to use and [get] the latest, fixed the issue.
See the "Threading" section of this page: http://msdn.microsoft.com/en-us/library/ff647786.aspx, in conjunction with the "Connections" section.
Have you tried upping the maxconnection attribute of your processModel setting?
IIS7 defines a defaultDocument section in its configuration files which can be found in the %WinDir%\System32\InetSrv\Config folder. Most likely, the file index.aspx is already defined as a default document in one of IIS7's configuration files and you are adding it again in your web.config.
I suspect that removing the line
<add value="index.aspx" />
from the defaultDocument/files section will fix your issue.
The defaultDocument section of your config will look like:
<defaultDocument>
<files>
<remove value="default.aspx" />
<remove value="index.html" />
<remove value="iisstart.htm" />
<remove value="index.htm" />
<remove value="Default.asp" />
<remove value="Default.htm" />
</files>
</defaultDocument>
Note that index.aspx will still appear in the list of default documents for your site in the IIS manager.

What you posted has a syntax error, but it makes no difference as you cannot pass HTTP headers via $.post()
.
Provided you're on jQuery version >= 1.5, switch to $.ajax()
and pass the headers
(docs) option. (If you're on an older version of jQuery, I will show you how to do it via the beforeSend
option.)
$.ajax({

type: 'post',
data: {
access_token: 'XXXXXXXXXXXXXXXXXXX'
},
headers: {
Header_Name_One: 'Header Value One', //If your header name has spaces or any other char not appropriate
"Header Name Two": 'Header Value Two' //for object property name, use quoted notation shown in second
},

Just as an FYI, there is a library called breakpoints which detects the max-width as set in CSS and allows you to use it in JS if-else conditions using <=, <, >, >= and == signs. I found it quite useful. The payload size is under 3 KB.
This awnser solved my problem. Below is a copy of it:
Make sure to start you JVM with -Dfile.encoding=UTF-8. You JVM defaults to the operating system charset
This is a JVM argument which could be added, for example, either to JBoss standalone or JBoss running from Eclipse.

IE <= 9 doesn't support CORS. I've written a javascript that will automatically route those requests through a proxy. It's all 100% transparent (you just have to include my proxy and the script).
Download it using nuget corsproxy
and follow the included instructions.
By using Spring 3.1.x and 3.2.x, this is how you should do it:
The controller method:
@RequestMapping("/photo2")
public @ResponseBody byte[] testphoto() throws IOException {
InputStream in = servletContext.getResourceAsStream("/images/no_image.jpg");
return IOUtils.toByteArray(in);
}
And the mvc annotation in servlet-context.xml file:
<mvc:annotation-driven>
<mvc:message-converters>
<bean class="org.springframework.http.converter.ByteArrayHttpMessageConverter">
<property name="supportedMediaTypes">
<list>
<value>image/jpeg</value>

Declaration of new variables in case statements is what causing problems. Enclosing all case

I found php-cgi on my server. And its on environment path so I was able to run from anywhere. I executed succesfuly file.php
in my bash script.
#!/bin/bash
php-cgi ../path/file.php
And the script returned this after php script was executed:
X-Powered-By: PHP/7.1.1 Content-type: text/html; charset=UTF-8
done!
By the way, check first if it works by checking the version issuing the command php-cgi -v
That is, you are referencing an image, but instead of providing an external url, the png image data is in the url itself, embedded in the style sheet. data:image/png;base64 tells the browser that the data is inline, is a png image and is in this case base64 encoded. The encoding is needed because png images can contain bytes that are invalid inside a HTML document (or within the HTTP protocol even).

Whenever one writes [A-Z]
or [a-z]
, one explicitly commits to
processing nothing but 7-bit ASCII data from the 1960s. If that’s
really ok, then fine. But if it’s not ok, then Unicode character
properties exist to help you with handling modern character data.
There are three cases in Unicode, not two. Furthermore, you also have
noncased letters. Letters in general are specified by the \pL
property,
and each of these also belongs to exactly one of five subcategories:
\p{Lu}
; eg: AÇ?ÞSSS??ST\p{Lt}
; eg: ??Ss?St
(actually Ss
and St
are an upper- and then a lowercase letter,
but they are what you get if you ask for the titlecase of ß and
?, respectively)\p{Ll}
; eg: aaç??sþß??\p{Lm}
; eg: ????"'???\p{Lo}
; eg: ?????You can take the complement of any of these, but do be careful, because
something like \P{Lu}
does not mean a letter that isn’t uppercase!
It means any character that isn’t an uppercase letter.
For a letter that’s either of uppercase or titlecase, use
[\p{Lu}\p{Lt}]
. So you could use for your pattern:
^([\p{Lu}\p{Lt}]\p{Ll}+)+$
If you don’t mean to limit the letters following the first to the “casing” letters alone, then you might prefer:
^([\p{Lu}\p{Lt}][\p{Ll}\p{Lm}\p{Lo}]+)+$
If you’re trying to match so-called “CamelCase” identifiers, then
the actual rules depend on the programming language, but usually include
the underscore character and the decimal numbers (\p{Nd}
), and may also
include a literal dollar sign and other language-dependent characters.
If so, you may wish to add some of these to one or the other of the two
character classes provided above.
For example, you may wish to add underscore to both but digits only to the second, leaving you with:
^([_\p{Lu}\p{Lt}][_\p{Nd}\p{Ll}\p{Lm}\p{Lo}]+)+$
If, though, you are dealing with certain “words” from various RFCs and ISO
standards, these are often specified as containing ASCII only. If so,
you can get by with the literal [A-Z]
idea. It’s just not kind to
impose that restriction if it doesn’t actually exist.
You can perform tasks for a limited time after your application is directed to go to the background, but only for the duration provided. Running for longer than this will cause your application to be terminated. See the "Completing a Long-Running Task in the Background" section of the iOS Application Programming Guide for how to go about this.
Others have piggybacked on playing audio in the background as a means of staying alive as a background process, but Apple will only accept such an application if the audio playback is a legitimate function. Item 2.16 on Apple's published review guidelines states:
Multitasking apps may only use background services for their intended purposes: VoIP, audio playback, location, task completion, local notifications, etc
When our page is idle for x amount of time the view will expire and throw javax.faces.application.ViewExpiredException to prevent this from happening one solution is to create CustomViewHandler that extends ViewHandler and override restoreView method all the other methods are being delegated to the Parent
import java.io.IOException;
import javax.faces.FacesException;
import javax.faces.application.ViewHandler;
import javax.faces.component.UIViewRoot;
import javax.faces.context.FacesContext;
import javax.servlet.http.HttpServletRequest;
public class CustomViewHandler extends ViewHandler {
private ViewHandler parent;
public CustomViewHandler(ViewHandler parent) {
//System.out.println("CustomViewHandler.CustomViewHandler():Parent View Handler:"+parent.getClass());
this.parent = parent;
}
@Override
public UIViewRoot restoreView(FacesContext facesContext, String viewId) {
/**
* {@link javax.faces.application.ViewExpiredException}. This happens only when we try to logout from timed out pages.
*/
UIViewRoot root = null;
root = parent.restoreView(facesContext, viewId);
if(root == null) {
root = createView(facesContext, viewId);
}
return root;
}
@Override
public Locale calculateLocale(FacesContext facesContext) {
return parent.calculateLocale(facesContext);
}
@Override
public String calculateRenderKitId(FacesContext facesContext) {
String renderKitId = parent.calculateRenderKitId(facesContext);
//System.out.println("CustomViewHandler.calculateRenderKitId():RenderKitId: "+renderKitId);
return renderKitId;
}
@Override
public UIViewRoot createView(FacesContext facesContext, String viewId) {
return parent.createView(facesContext, viewId);
}
@Override
public String getActionURL(FacesContext facesContext, String actionId) {
return parent.getActionURL(facesContext, actionId);
}
@Override
public String getResourceURL(FacesContext facesContext, String resId) {
return parent.getResourceURL(facesContext, resId);
}
@Override
public void renderView(FacesContext facesContext, UIViewRoot viewId) throws IOException, FacesException {
parent.renderView(facesContext, viewId);
}
@Override
public void writeState(FacesContext facesContext) throws IOException {
parent.writeState(facesContext);
}
public ViewHandler getParent() {
return parent;
}
}
Then you need to add it to your faces-config.xml
<application>
<view-handler>com.demo.CustomViewHandler</view-handler>
</application>

Would it not be better to use java.util.Observable
and java.util.Observer
that will cause the table to update?
Your code sets the timeout to 1000 seconds. For milliseconds, use CURLOPT_TIMEOUT_MS
.
I had the same issue in Windows 7.
The solution was to go to basic settings > connect as > specific user - and log in as a user, instead of the default 'pass-through'
This fixed the issue for me.
This may happen when the same classname is specified in multiple .aspx.cs
files, i.e.
when two pages are created with different file name but by mistake have the same classname.
// file a.aspx
public partial class Test1: System.Web.UI.Page
// file b.aspx
public partial class Test1: System.Web.UI.Page
While building the webapplication this gives a warning, but the application runs, however, after publishing the application doesn't work anymore and throws the exception as mentioned in the OP's question.
Making sure that two classnames do no overlap solves the issue.
I have seen that the new versions when you define the resulting entities better define them in the following way if you handle a different scheme, I had a similar problem
You must add System.ComponentModel.DataAnnotations.Schema
using System.ComponentModel.DataAnnotations.Schema;
[Table("InstitucionesMilitares", Schema = "configuracion")]
I added a parameterless constructor to the model inside of DOMAIN Folder, and the problem is solved.
public User()
{
}
FYI you can also get this error if EF Migrations tries to run with no Db configured, for example in a Test Project.
Chased this for hours before I figured out that it was erroring on a query, but, not because of the query but because it was when Migrations kicked in to try to create the Db.
Any Class that implements System.Web.IHttpHandler
Interface becomes HttpHandler
. And this class run as processes in response to a request made to the ASP.NET Site.
The most common handler is an ASP.NET page handler that processes .aspx files. When users request an .aspx file, the request is processed by the page through the page handler(The Class that implements System.Web.IHttpHandler
Interface).
You can create your own custom HTTP handlers that render custom output to the browser.
Some ASP.NET default handlers are:
It seems that you have forgotten to add your state server address in the config file.
<sessionstate mode="StateServer" timeout="20" server="127.0.0.1" port="42424" />
Just to clarify the problem here - the error is in the following bit of code:
<xsl:attribute name="src">
<xsl:copy-of select="/root/Image/node()"/>
</xsl:attribute>
The instruction xsl:copy-of takes a node or node-set and makes a copy of it - outputting a node or node-set. However an attribute cannot contain a node, only a textual value, so xsl:value-of would be a possible solution (as this returns the textual value of a node or nodeset).
A MUCH shorter solution (and perhaps more elegant) would be the following:
<img width="100" height="100" src="{/root/Image/node()}" class="CalloutRightPhoto"/>
The use of the {} in the attribute is called an Attribute Value Template, and can contain any XPATH expression.
Note, the same XPath can be used here as you have used in the xsl_copy-of as it knows to take the textual value when used in a Attribute Value Template.
You can also dump elasticsearch data in JSON format by http request:

You have to select the device in the schemes menu in the top left where you used to select between simulator/device. It won’t let you archive a build for the simulator.
Or you may find that if the iOS device is already selected the archive box isn’t selected when you choose “Edit Schemes” => “Build”.

Replace getSupportFragmentManager()
with getFragmentManager()
if you are working in api 21.
OR
If your app supports versions of Android older than 3.0, be sure you've set up your Android project with the support library as described in Setting Up a Project to Use a Library and use getSupportFragmentManager()
this time.
I usually use this parser from codeproject, since there's a bunch of character escapes and similar that it handles for me.
Probably the easiest way is:
SELECT EXTRACT(epoch FROM my_interval)/3600
if you are using target sdk as 23 add below code in your build.gradle
android{
useLibrary 'org.apache.http.legacy'
}
additional note here: dont try using the gradle versions of those files. they are broken (28.08.15). I tried over 5 hours to get it to work. it just doesnt. not working:
compile 'org.apache.httpcomponents:httpcore:4.4.1'
compile 'org.apache.httpcomponents:httpclient:4.5'
another thing dont use:
'org.apache.httpcomponents:httpclient-android:4.3.5.1'
its referring 21 api level.
I want to just refresh the div, without refreshing the page ... Is this possible?
Yes, though it isn't going to be obvious that it does anything unless you change the contents of the div.
If you just want the graphical fade-in effect, simply remove the .html(data)
call:
$("#panel").hide().fadeIn('fast');
Here is a demo you can mess around with: http://jsfiddle.net/ZPYUS/
It changes the contents of the div without making an ajax call to the server, and without refreshing the page. The content is hard coded, though. You can't do anything about that fact without contacting the server somehow: ajax, some sort of sub-page request, or some sort of page refresh.
html:
<div id="panel">test data</div>
<input id="changePanel" value="Change Panel" type="button">?
javascript:
$("#changePanel").click(function() {
var data = "foobar";
$("#panel").hide().html(data).fadeIn('fast');
});?
css:
div {
padding: 1em;
background-color: #00c000;
}
input {
padding: .25em 1em;
}?
OK some answers about malloc were already posted.
The more interesting part is how free works (and in this direction, malloc too can be understood better).
In many malloc/free implementations, free does normally not return the memory to the operating system (or at least only in rare cases). The reason is that you will get gaps in your heap and thus it can happen, that you just finish off your 2 or 4 GB of virtual memory with gaps. This should be avoided, since as soon as the virtual memory is finished, you will be in really big trouble. The other reason is, that the OS can only handle memory chunks that are of a specific size and alignment. To be specific: Normally the OS can only handle blocks that the virtual memory manager can handle (most often multiples of 512 bytes e.g. 4KB).
So returning 40 Bytes to the OS will just not work. So what does free do?
Free will put the memory block in its own free block list. Normally it also tries to meld together adjacent blocks in the address space. The free block list is just a circular list of memory chunks which have some administrative data in the beginning. This is also the reason why managing very small memory elements with the standard malloc/free is not efficient. Every memory chunk needs additional data and with smaller sizes more fragmentation happens.
The free-list is also the first place that malloc looks at when a new chunk of memory is needed. It is scanned before it calls for new memory from the OS. When a chunk is found that is bigger than the needed memory, it is divided into two parts. One is returned to caller, the other is put back into the free list.
There are many different optimizations to this standard behaviour (for example for small chunks of memory). But since malloc and free must be so universal, the standard behaviour is always the fallback when alternatives are not usable. There are also optimizations in handling the free-list — for example storing the chunks in lists sorted by sizes. But all optimizations also have their own limitations.
Why does your code crash:
The reason is that by writing 9 chars (don't forget the trailing null byte) into an area sized for 4 chars, you will probably overwrite the administrative-data stored for another chunk of memory that resides "behind" your chunk of data (since this data is most often stored "in front" of the memory chunks). When free then tries to put your chunk into the free list, it can touch this administrative-data and therefore stumble over an overwritten pointer. This will crash the system.
This is a rather graceful behaviour. I have also seen situations where a runaway pointer somewhere has overwritten data in the memory-free-list and the system did not immediately crash but some subroutines later. Even in a system of medium complexity such problems can be really, really hard to debug! In the one case I was involved, it took us (a larger group of developers) several days to find the reason of the crash -- since it was in a totally different location than the one indicated by the memory dump. It is like a time-bomb. You know, your next "free" or "malloc" will crash, but you don't know why!
Those are some of the worst C/C++ problems, and one reason why pointers can be so problematic.
The following are the major differences between procedure and function,

In Java 8+ you can create a max priority queue via one of these methods:
Method 1:
PriorityQueue<Integer> maxPQ = new PriorityQueue<>(Collections.reverseOrder());
Method 2:
PriorityQueue<Integer> maxPQ = new PriorityQueue<>((a,b) -> b - a);
Method 3:
PriorityQueue<Integer> maxPQ = new PriorityQueue<>((a,b) -> b.compareTo(a));
Take a look at the domReady script that allows setting up of multiple functions to execute when the DOM has loaded. It's basically what the Dom ready does in many popular JavaScript libraries, but is lightweight and can be taken and added at the start of your external script file.
Example usage
// add reference to domReady script or place
// contents of script before here
function codeAddress() {
}
domReady(codeAddress);
using alberT and Dan Tao solution:
negative to positive and viceversa

I happened to work on some Spark exercise, here is my solution.
tokens = ['quick', 'brown', 'fox', 'jumps', 'lazy', 'dog']
print {n: float(tokens.count(n))/float(len(tokens)) for n in tokens}
**#output of the above **
{'brown': 0.16666666666666666, 'lazy': 0.16666666666666666, 'jumps': 0.16666666666666666, 'fox': 0.16666666666666666, 'dog': 0.16666666666666666, 'quick': 0.16666666666666666}

One thing to note: in order for that to make a difference you need to have built python
with +universal
, if you haven't or you're not sure you can just rebuild python +universal
. This applies to both brew as well as macports.
$ brew reinstall python
$ brew install boost
OR
$ sudo port -f uninstall python
$ sudo port install python +universal
$ sudo port install boost +universal

The .cpp
file is configured to use precompiled header, therefore it must be included first (before iostream). For Visual Studio, it's name is usually "stdafx.h".
If there are no stdafx* files in your project, you need to go to this file's options and set it as “Not using precompiled headers”.
OK, finally got it working: see https://github.com/angular/angular/pull/10314#issuecomment-242218563
In brief, you can no longer use name
attribute within a formGroup
, and must use formControlName
instead
The zip()
function in Python 3 returns an iterator. That is the reason why when you print test1
you get - <zip object at 0x1007a06c8>
. From documentation -
Make an iterator that aggregates elements from each of the iterables.
But once you do - list(test1)
- you have exhausted the iterator. So after that anytime you do list(test1)
would only result in empty list.
In case of test2
, you have already created the list once, test2
is a list, and hence it will always be that list.
The difference between these two methods is:
parseXxx()
returns the primitive typevalueOf()
returns a wrapper object reference of the type.I have an answer here:

Just create a new class extending ScrollView and override it's onMeasure
method.
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
if (maxHeight > 0){
int hSize = MeasureSpec.getSize(heightMeasureSpec);
int hMode = MeasureSpec.getMode(heightMeasureSpec);
switch (hMode){
case MeasureSpec.AT_MOST:
heightMeasureSpec = MeasureSpec.makeMeasureSpec(Math.min(hSize, maxHeight), MeasureSpec.AT_MOST);
break;
case MeasureSpec.UNSPECIFIED:
heightMeasureSpec = MeasureSpec.makeMeasureSpec(maxHeight, MeasureSpec.AT_MOST);
break;
case MeasureSpec.EXACTLY:
heightMeasureSpec = MeasureSpec.makeMeasureSpec(Math.min(hSize, maxHeight), MeasureSpec.EXACTLY);
break;
}
}
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
you can also do this using mounted
https://vuejs.org/v2/guide/migration.html#ready-replaced
....
methods:{
getUnits: function() {...}
},
mounted: function(){
this.$nextTick(this.getUnits)
}
....
overflow: auto;
or overflow: hidden;
should do it I think.
Dictionary is the most common, but you can use other types of collections, e.g. System.Collections.Generic.SynchronizedKeyedCollection, System.Collections.Hashtable, or any KeyValuePair collection
This appears to be a bug in the SelectExtensions class as it will only check the ViewData rather than the model for the selected item. So the trick is to copy the selected item from the model into the ViewData collection under the name of the property.
This is taken from the answer I gave on the MVC forums, I also have a more complete answer in a blog post that uses Kazi's DropDownList attribute...
Given a model
public class ArticleType
{
public Guid Id { get; set; }
public string Description { get; set; }
}
public class Article
{
public Guid Id { get; set; }
public string Name { get; set; }
public ArticleType { get; set; }
}
and a basic view model of
public class ArticleModel
{
public Guid Id { get; set; }
public string Name { get; set; }
[UIHint("DropDownList")]
public Guid ArticleType { get; set; }
}
Then we write a DropDownList editor template as follows..
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %>
<script runat="server">
IEnumerable<SelectListItem> GetSelectList()
{
var metaData = ViewData.ModelMetadata;
if (metaData == null)
{
return null;
}
var selected = Model is SelectListItem ? ((SelectListItem) Model).Value : Model.ToString();
ViewData[metaData.PropertyName] = selected;
var key = metaData.PropertyName + "List";
return (IEnumerable<SelectListItem>)ViewData[key];
}
</script>
<%= Html.DropDownList(null, GetSelectList()) %>
This will also work if you change ArticleType in the view model to a SelectListItem, though you do have to implement a type converter as per Kazi's blog and register it to force the binder to treat this as a simple type.
In your controller we then have...
public ArticleController
{
...
public ActionResult Edit(int id)
{
var entity = repository.FindOne<Article>(id);
var model = builder.Convert<ArticleModel>(entity);
var types = repository.FindAll<ArticleTypes>();
ViewData["ArticleTypeList"] = builder.Convert<SelectListItem>(types);
return VIew(model);
}
...
}
There is no need to install Anaconda again. Conda, the package manager for Anaconda, fully supports separated environments. The easiest way to create an environment for Python 2.7 is to do
conda create -n python2 python=2.7 anaconda
This will create an environment named python2
that contains the Python 2.7 version of Anaconda. You can activate this environment with
source activate python2
This will put that environment (typically ~/anaconda/envs/python2
) in front in your PATH
, so that when you type python
at the terminal it will load the Python from that environment.
If you don't want all of Anaconda, you can replace anaconda
in the command above with whatever packages you want. You can use conda
to install packages in that environment later, either by using the -n python2
flag to conda
, or by activating the environment.
This should work:
txtfarmersize = Convert.ToInt32(reader["farmsize"]);
In Firefox, these function behave quite differently: log
only prints out a toString
representation, whereas dir
prints out a navigable tree.
In Chrome, log
already prints out a tree -- most of the time. However, Chrome's log
still stringifies certain classes of objects, even if they have properties. Perhaps the clearest example of a difference is a regular expression:
> console.log(/foo/);
/foo/
> console.dir(/foo/);
* /foo/
global: false
ignoreCase: false
lastIndex: 0
...
You can also see a clear difference with arrays (e.g., console.dir([1,2,3])
) which are log
ged differently from normal objects:
> console.log([1,2,3])
[1, 2, 3]
> console.dir([1,2,3])
* Array[3]
0: 1
1: 2
2: 3
length: 3
* __proto__: Array[0]
concat: function concat() { [native code] }
constructor: function Array() { [native code] }
entries: function entries() { [native code] }
...
DOM objects also exhibit differing behavior, as noted on another answer.
If you Want to copy Same DataBase
Select * INTO NewTableName from OldTableName
If Another DataBase
Select * INTO NewTableName from DatabaseName.OldTableName
You can break up long lines with the caret ^
as long as you remember that the caret and the newline following it are completely removed. So, if there should be a space where you're breaking the line, include a space. (More on that below.)
Example:
copy file1.txt file2.txt
would be written as:
copy file1.txt^
file2.txt
sed 's/^.\{5\}//' logfile
and you replace 5 by the number you want...it should do the trick...
EDIT
if for each line
sed 's/^.\{5\}//g' logfile

I know I'm a little late to the party, but I did want to throw some interjections. (I would have commented but not enough reputation points yet, so, here's a full answer).
This requires the latest version of VS Code, Azure Repo Extention, and Git to be installed.
Anyone looking to use the new VS Code (or using the preview like myself), when you go to the Settings (Still File -> Preferences -> Settings or CTRL+, ) you'll be looking under User Settings -> Extensions -> Azure Repos.
Then under Tfvc: Location you can paste the location of the executable.
For 2017 it'll be
C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer\TF.exe
Or for 2019 (Preview)
C:\Program Files (x86)\Microsoft Visual Studio\2019\Preview\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer\TF.exe
After adding the location, I closed my VS Code (not sure if this was needed) and went my git repo to copy the git URL.
After that, went back into VS Code went to the Command Palette (View -> Command Palette or CTRL+Shift+P) typed Git: Clone
pasted my repo:
Selected the location for the repo to be stored. Next was an error that popped up. I proceeded to follow this video which walked me through clicking on the Team button with the exclamation mark on the bottom of your VS Code Screen
Then chose the new method of authentication
Copy by using CTRL+C and then press enter. Your browser will launch a page where you'll enter the code you copied (CTRL+V).
Click Continue
Log in with your Microsoft Credentials and you should see a change on the bottom bar of VS Code.
Cheers!
Like others said, you can just loop over the array and print out the elements one by one. To make the output show up as numbers instead of "letters and symbols" you were seeing, you need to convert each element to a string. So your code becomes something like this:
public static void write (String filename, int[]x) throws IOException{
BufferedWriter outputWriter = null;
outputWriter = new BufferedWriter(new FileWriter(filename));
for (int i = 0; i < x.length; i++) {
// Maybe:
outputWriter.write(x[i]+"");
// Or:
outputWriter.write(Integer.toString(x[i]);
outputWriter.newLine();
}
outputWriter.flush();
outputWriter.close();
}
If you just want to print out the array like [1, 2, 3, ....]
, you can replace the loop with this one liner:
outputWriter.write(Arrays.toString(x));
First you download ODBC driver psqlodbc_09_01_0200-x64.zip then you installed it.After that go to START->Program->Administrative tools then you select Data Source ODBC then you double click on the same after that you select PostgreSQL 30 then you select configure then you provide proper details such as db name user Id host name password of the same database in this way you will configured your DSN connection.After That you will check SSL should be allow .
Then you go on next tab system DSN then you select ADD tabthen select postgreSQL_ANSI_64X ODBC after you that you have created PostgreSQL ODBC connection.
None of the above answers worked for me, but I got it working with the following:

function convertCase(str) {
var lower = String(str).toLowerCase();
return lower.replace(/(^| )(\w)/g, function(x) {
return x.toUpperCase();
});
}

First the bigint(20) not null auto_increment
will not work, simply use bigserial primary key
. Then datetime
is timestamp
in PostgreSQL. All in all:
CREATE TABLE article (
article_id bigserial primary key,
article_name varchar(20) NOT NULL,
article_desc text NOT NULL,
date_added timestamp default NULL
);
Since the add-ons don't work anymore, the most helpful set of tools I've found is using Visual Studio/IE because you can set breakpoints in your JS and inspect your data that way. Of course Chrome and Firefox have much better dev tools in general. Also, good ol' console.log() has been super helpful!
For those that pointed out the fact that you can't use the toString method of InputStream like this see https://stackoverflow.com/a/5445161/1304830 :
My correct answer would be then :
import org.json.JSONObject;

Some great news! Since version 3.6 the cPython implementation has preserved the insertion order of dictionaries (https://mail.python.org/pipermail/python-dev/2016-September/146327.html). This means that the json library is now order preserving by default. Observe the difference in behaviour between python 3.5 and 3.6. The code:
import json
data = json.loads('{"foo":1, "bar":2, "fiddle":{"bar":2, "foo":1}}')
print(json.dumps(data, indent=4))
In py3.5 the resulting order is undefined:
{
"fiddle": {
"bar": 2,
"foo": 1
},
"bar": 2,
"foo": 1
}
In the cPython implementation of python 3.6:
{
"foo": 1,
"bar": 2,
"fiddle": {
"bar": 2,
"foo": 1
}
}
The really great news is that this has become a language specification as of python 3.7 (as opposed to an implementation detail of cPython 3.6+): https://mail.python.org/pipermail/python-dev/2017-December/151283.html
So the answer to your question now becomes: upgrade to python 3.6! :)
Set an id to the option then use get element by id and disable it when x value has been selected..
example
<body>
<select class="pull-right text-muted small"
name="driveCapacity" id=driveCapacity onchange="checkRPM()">
<option value="4000.0" id="4000">4TB</option>
<option value="900.0" id="900">900GB</option>
<option value="300.0" id ="300">300GB</option>
</select>
</body>
<script>
var perfType = document.getElementById("driveRPM").value;
if(perfType == "7200"){
document.getElementById("driveCapacity").value = "4000.0";
document.getElementById("4000").disabled = false;
}else{
document.getElementById("4000").disabled = true;
}
</script>
The short answer for old versions of Rails (see other answers for Rails 4+):
add_index :table_name, :column_name, unique: true
To index multiple columns together, you pass an array of column names instead of a single column name,
add_index :table_name, [:column_name_a, :column_name_b], unique: true
If you get "index name... is too long", you can add name: "whatever"
to the add_index method to make the name shorter.
For fine-grained control, there's a "execute
" method that executes straight SQL.
That's it!
If you are doing this as a replacement for regular old model validations, check to see how it works. The error reporting to the user will likely not be as nice without model-level validations. You can always do both.
I am using Bootstrap & HTML5. I wanted to override the look of the toggle button.

Add column to your migration file and run this command.
php artisan migrate:refresh --path=/database/migrations/your_file_name.php
you can always convert your varchar-column to bigint as integer might be too short...
select cast([yourvarchar] as BIGINT)
but you should always care for alpha characters
where ISNUMERIC([yourvarchar] +'e0') = 1
the +'e0' comes from http://blogs.lessthandot.com/index.php/DataMgmt/DataDesign/isnumeric-isint-isnumber
this would lead to your statement
SELECT
*
FROM
Table
ORDER BY
ISNUMERIC([yourvarchar] +'e0') DESC
, LEN([yourvarchar]) ASC
the first sorting column will put numeric on top. the second sorts by length, so 10 will preceed 0001 (which is stupid?!)
this leads to the second version:
SELECT
*
FROM
Table
ORDER BY
ISNUMERIC([yourvarchar] +'e0') DESC
, RIGHT('00000000000000000000'+[yourvarchar], 20) ASC
the second column now gets right padded with '0', so natural sorting puts integers with leading zeros (0,01,10,0100...) in correct order (correct!) - but all alphas would be enhanced with '0'-chars (performance)
so third version:
SELECT
*
FROM
Table
ORDER BY
ISNUMERIC([yourvarchar] +'e0') DESC
, CASE WHEN ISNUMERIC([yourvarchar] +'e0') = 1
THEN RIGHT('00000000000000000000' + [yourvarchar], 20) ASC
ELSE LTRIM(RTRIM([yourvarchar]))
END ASC
now numbers first get padded with '0'-chars (of course, the length 20 could be enhanced) - which sorts numbers right - and alphas only get trimmed

If you want to keep the database between uninstalls you have to put it on the SD Card. This is the only place that won't be deleted at the moment your app is deleted. But in return it can be deleted by the user every time.
If you put your DB on the SD Card you can't use the SQLiteOpenHelper anymore, but you can use the source and the architecture of this class to get some ideas on how to implement the creation, updating and opening of a databse.
To append to an array, just use the +=
operator.
$Target += $TargetObject
Also, you need to declare $Target = @()
before your loop because otherwise, it will empty the array every loop.
It's a little difficult to tell what you're trying to achieve, but assuming you're trying to get a Base64 string that when decoded is abcdef==
, the following should work:
byte[] bytes = Encoding.UTF8.GetBytes("abcdef==");
string base64 = Convert.ToBase64String(bytes);
Console.WriteLine(base64);
This will output: YWJjZGVmPT0=
which is abcdef==
encoded in Base64.
Edit:
To decode a Base64 string, simply use Convert.FromBase64String()
. E.g.
string base64 = "YWJjZGVmPT0=";
byte[] bytes = Convert.FromBase64String(base64);
At this point, bytes
will be a byte[]
(not a string
). If we know that the byte array represents a string in UTF8, then it can be converted back to the string form using:
string str = Encoding.UTF8.GetString(bytes);
Console.WriteLine(str);
This will output the original input string, abcdef==
in this case.
Yes, Java (similar to other mainstream languages) uses lazy evaluation short-circuiting which means it evaluates as little as possible.
This means that the following code is completely safe:
if(p != null && p.getAge() > 10)
Also, a || b
never evaluates b
if a
evaluates to true
.
I don't know of any way doing this in SQL Developer. You can see all the other schemas and their objects (if you have the correct privileges) when looking in "Other Users" -> "< Schemaname >".
In your case, either use the method described above or create a new connection for the schema in which you want to work or create synonyms for all the tables you wish to access.
If you would work in SQL*Plus, issuing ALTER SESSION SET CURRENT_SCHEMA=MY_NAME
would set your current schema (This is probably what your DBA means).
Portmon from sysinternals (now MSFT) is probably the best monitor.
I haven't found a good free tool that will emulate a port and record/replay comms. The commercial ones were expensive and either so limited or so complex if you want to respond to commands that I ended up using expect and python on a second machine.
You can simply use Arrays.sort()
array.sort((a,b) => a.title.rendered.localeCompare(b.title.rendered));
Working Example :
var array = [{"id":3645,"date":"2018-07-05T13:13:37","date_gmt":"2018-07-05T13:13:37","guid":{"rendered":""},"modified":"2018-07-05T13:13:37","modified_gmt":"2018-07-05T13:13:37","slug":"vpwin","status":"publish","type":"matrix","link":"","title":{"rendered":"VPWIN"},"content":{"rendered":"","protected":false},"featured_media":0,"parent":0,"template":"","better_featured_image":null,"acf":{"domain":"SMB","ds_rating":"3","dt_rating":""},},{"id":3645,"date":"2018-07-05T13:13:37","date_gmt":"2018-07-05T13:13:37","guid":{"rendered":""},"modified":"2018-07-05T13:13:37","modified_gmt":"2018-07-05T13:13:37","slug":"vpwin","status":"publish","type":"matrix","link":"","title":{"rendered":"adfPWIN"},"content":{"rendered":"","protected":false},"featured_media":0,"parent":0,"template":"","better_featured_image":null,"acf":{"domain":"SMB","ds_rating":"3","dt_rating":""}},{"id":3645,"date":"2018-07-05T13:13:37","date_gmt":"2018-07-05T13:13:37","guid":{"rendered":""},"modified":"2018-07-05T13:13:37","modified_gmt":"2018-07-05T13:13:37","slug":"vpwin","status":"publish","type":"matrix","link":"","title":{"rendered":"bbfPWIN"},"content":{"rendered":"","protected":false},"featured_media":0,"parent":0,"template":"","better_featured_image":null,"acf":{"domain":"SMB","ds_rating":"3","dt_rating":""}}];_x000D_

How about mkString ?
theStrings.mkString(",")
A variant exists in which you can specify a prefix and suffix too.
See here for an implementation using foldLeft, which is much more verbose, but perhaps worth looking at for education's sake.

select 1 from table
will return a column of 1's for every row in the table. You could use it with a where statement to check whether you have an entry for a given key, as in:
if exists(select 1 from table where some_column = 'some_value')
What your friend was probably saying is instead of making bulk selects with select * from table, you should specify the columns that you need precisely, for two reasons:
1) performance & you might retrieve more data than you actually need.
2) the query's user may rely on the order of columns. If your table gets updated, the client will receive columns in a different order than expected.

Here's what happens when a browser loads a website with a <script>
tag on it:
<script>
tag referencing an external script file.Step #4 causes a bad user experience. Your website basically stops loading until you've downloaded all scripts. If there's one thing that users hate it's waiting for a website to load.
Any script can insert its own HTML via document.write()
or other DOM manipulations. This implies that the parser has to wait until the script has been downloaded & executed before it can safely parse the rest of the document. After all, the script could have inserted its own HTML in the document.
However, most JavaScript developers no longer manipulate the DOM while the document is loading. Instead, they wait until the document has been loaded before modifying it. For example:
<!-- index.html -->
<html>
<head>
<title>My Page</title>
<script src="my-script.js"></script>
</head>
<body>
<div id="user-greeting">Welcome back, user</div>
</body>
</html>
Javascript:
// my-script.js
document.addEventListener("DOMContentLoaded", function() {
// this function runs when the DOM is ready, i.e. when the document has been parsed
document.getElementById("user-greeting").textContent = "Welcome back, Bart";
});
Because your browser does not know my-script.js isn't going to modify the document until it has been downloaded & executed, the parser stops parsing.
The old approach to solving this problem was to put <script>
tags at the bottom of your <body>
, because this ensures the parser isn't blocked until the very end.
This approach has its own problem: the browser cannot start downloading the scripts until the entire document is parsed. For larger websites with large scripts & stylesheets, being able to download the script as soon as possible is very important for performance. If your website doesn't load within 2 seconds, people will go to another website.
In an optimal solution, the browser would start downloading your scripts as soon as possible, while at the same time parsing the rest of your document.
Today, browsers support the async
and defer
attributes on scripts. These attributes tell the browser it's safe to continue parsing while the scripts are being downloaded.
<script src="path/to/script1.js" async></script>
<script src="path/to/script2.js" async></script>
Scripts with the async attribute are executed asynchronously. This means the script is executed as soon as it's downloaded, without blocking the browser in the meantime.
This implies that it's possible to script 2 is downloaded & executed before script 1.
According to http://caniuse.com/#feat=script-async, 97.78% of all browsers support this.
<script src="path/to/script1.js" defer></script>
<script src="path/to/script2.js" defer></script>
Scripts with the defer attribute are executed in order (i.e. first script 1, then script 2). This also does not block the browser.
Unlike async scripts, defer scripts are only executed after the entire document has been loaded.
According to http://caniuse.com/#feat=script-defer, 97.79% of all browsers support this. 98.06% support it at least partially.
An important note on browser compatibility: in some circumstances IE <= 9 may execute deferred scripts out of order. If you need to support those browsers, please read this first!
The current state-of-the-art is to put scripts in the <head>
tag and use the async
or defer
attributes. This allows your scripts to be downloaded asap without blocking your browser.
The good thing is that your website should still load correctly on the 2% of browsers that do not support these attributes while speeding up the other 98%.

Since position: absolute;
and viewport width were no options in my special case, there is another quick solution to solve the problem. The only condition is, that overflow in x-direction is not necessary for your website.
You can define negative margins for your element:
#help_panel {
margin-left: -9999px;
margin-right: -9999px;
}
But since we get overflow doing this, we have to avoid overflow in x-direction globally e.g. for body:
body {
overflow-x: hidden;
}
You can set padding
to choose the size of your content.
Note that this solution does not bring 100% width for content, but it is helpful in cases where you need e.g. a background color which has full width with a content still depending on container.
For objects you can nest the queries:
DB::table('orders')->find(DB::table('orders')->max('id'));
So the inside query looks up the max id in the table and then passes that to the find, which gets you back the object.
Here is a simple method to read the text file from the raw folder:
public static String readTextFile(Context context,@RawRes int id){
InputStream inputStream = context.getResources().openRawResource(id);
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
byte buffer[] = new byte[1024];
int size;
try {
while ((size = inputStream.read(buffer)) != -1) {
outputStream.write(buffer, 0, size);
}
outputStream.close();
inputStream.close();
} catch (IOException e) {
}
return outputStream.toString();
}
The other case involving print >>obj, "Hello World"
is the "print chevron" syntax for the print
statement in Python 2 (removed in Python 3, replaced by the file
argument of the print()
function). Instead of writing to standard output, the output is passed to the obj.write()
method. A typical example would be file objects having a write()
method. See the answer to a more recent question: Double greater-than sign in Python.
If you moved the modules, modify your workspace.xml file and settings.gradle file to use the new paths of your module. Otherwise you will need to try using the import module feature.
document.getElementById('foo').disabled = true;
or
document.getElementById('foo').readOnly = true;
Note that readOnly
should be in camelCase to work correctly in Firefox (magic).
Demo: https://jsfiddle.net/L96svw3c/ -- somewhat explains the difference between disabled
and readOnly
.

I needed binary search in python and generic for Django models. In Django models, one model can have foreign key to another model and I wanted to perform some search on the retrieved models objects. I wrote following function you can use this.
def binary_search(values, key, lo=0, hi=None, length=None, cmp=None):
"""
This is a binary search function which search for given key in values.
This is very generic since values and key can be of different type.
If they are of different type then caller must specify `cmp` function to

:param values: List of items in which key has to be search
:param key: search key
:param lo: start index to begin search
:param hi: end index where search will be performed
:param length: length of values

assert type(values[0]) == type(key) or cmp, "can't be compared"
assert not (hi and length), "`hi`, `length` both can't be specified at the same time"
lo = lo
if not lo:
lo = 0
if hi:
hi = hi
elif length:
hi = length - 1
else:
hi = len(values) - 1
while lo <= hi:
mid = lo + (hi - lo) // 2
if not cmp:

Great Start to learning login forms. You are right, fieldset may not be the best tag.
However, I highly suggest you code it in HTML5 by using its robust form features.
HTML5 is actually easier to learn than older HTML for creating forms.
For example, read the following.
<section class="loginform cf">
<form name="login" action="index_submit" method="get" accept-charset="utf-8">
<ul>
<li><label for="usermail">Email</label>
<input type="email" name="usermail" placeholder="[email protected]" required></li>
<li><label for="password">Password</label>
<input type="password" name="password" placeholder="password" required></li>
<li>
<input type="submit" value="Login"></li>
</ul>
</form>
</section>

Win32_USBHub
returns only USB Hubs. That seems obvious in hindsight but the discussion above misses it. It does not include all possible USB devices, only those which can (in theory, at least) act as a hub for additional devices. It misses some devices that are not hubs (particularly parts of composite devices).
Win32_PnPEntity
does include all the USB devices, and hundreds more non-USB devices. Russel Gantman's advice to use a WHERE clause search Win32_PnPEntity
for a DeviceID beginning with "USB%" to filter the list is helpful but slightly incomplete; it misses bluetooth devices, some printers/print servers, and HID-compliant mice and keyboards. I have seen "USB\%", "USBSTOR\%", "USBPRINT\%", "BTH\%", "SWD\%", and "HID\%". Win32_PnPEntity
is, however, a good "master" reference to look up information once you are in possession of the PNPDeviceID from other sources.
What I found was the best way to enumerate USB devices was to query Win32_USBControllerDevice
. While it doesn't give detailed information for the devices, it does completely enumerate your USB devices and gives you an Antecedent/Dependent pair of PNPDeviceID
s for every USB Device (including Hubs, non-Hub devices, and HID-compliant devices) on your system. Each Dependent returned from the query will be a USB Device. The Antecedent will be the Controller it is assigned to, one of the USB Controllers returned by querying Win32_USBController
.
As a bonus, it appears that under the hood, WMI walks the Device Tree when responding to the Win32_USBControllerDevice
query, so the order in which these results are returned can help identify parent/child relationships. (This is not documented and is thus only a guess; use the SetupDi API's CM_Get_Parent (or Child + Sibling) for definitive results.) As an option to the SetupDi API, it appears that for all the devices listed under Win32_USBHub
they can be looked up in the registry (at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\ + PNPDeviceID
) and will have a parameter ParentIdPrefix
which will be the prefix of the last field in the PNPDeviceID of its children, so this could also be used in a wildcard match to filter the Win32_PnPEntity
query.
In my application, I did the following:
Win32_PnPEntity
and stored the results in a key-value map (with PNPDeviceID as the key) for later retrieval. This is optional if you want to do individual queries later.Win32_USBControllerDevice
for a definitive list of USB devices on my system (all the Dependents) and extracted the PNPDeviceIDs of these. I went further, based on order following the device tree, to assign devices to the root hub (the first device returned, rather than the controller) and built a tree based on the parentIdPrefix. The order the query returns, which matches device tree enumeration via SetupDi, is each root hub (for whom the Antecedent identifies the controller), followed by an iteration of devices under it, e.g., on my system:
Win32_USBController
. This gave me the detailed information of the PNPDeviceIDs of my controllers which are at the top of the device tree (which were the Antecedents of the previous query). Using the tree derived in the previous step, recursively iterated over its children (the root hubs) and their children (the other hubs) and their children (non-hub devices and composite devices) and their children, etc.
Win32_PnPEntity
individually using the PNPDeviceId to get the information at this step; probably a cpu vs. memory tradeoff determining which order is better.)In summary, Win32USBControllerDevice
Dependents are a complete list of USB Devices on a system (other than the Controllers themselves, which are the Antecedents in that same query), and by cross-referencing these PNPDeviceId
pairs with information from the registry and from the other queries mentioned, a detailed picture can be constructed.
I created my own function to extract the rules from the decision trees created by sklearn:
import pandas as pd
import numpy as np
from sklearn.tree import DecisionTreeClassifier
# dummy data:
df = pd.DataFrame({'col1':[0,1,2,3],'col2':[3,4,5,6],'dv':[0,1,0,1]})
# create decision tree
dt = DecisionTreeClassifier(max_depth=5, min_samples_leaf=1)
dt.fit(df.ix[:,:2], df.dv)
This function first starts with the nodes (identified by -1 in the child arrays) and then recursively finds the parents. I call this a node's 'lineage'. Along the way, I grab the values I need to create if/then/else SAS logic:
def get_lineage(tree, feature_names):
left = tree.tree_.children_left
right = tree.tree_.children_right
threshold = tree.tree_.threshold
features = [feature_names[i] for i in tree.tree_.feature]
# get ids of child nodes
idx = np.argwhere(left == -1)[:,0]
def recurse(left, right, child, lineage=None):
if lineage is None:
lineage = [child]
if child in left:
parent = np.where(left == child)[0].item()
split = 'l'
else:
parent = np.where(right == child)[0].item()
split = 'r'
lineage.append((parent, split, threshold[parent], features[parent]))
if parent == 0:
lineage.reverse()
return lineage
else:
return recurse(left, right, parent, lineage)
for child in idx:
for node in recurse(left, right, child):
print node
The sets of tuples below contain everything I need to create SAS if/then/else statements. I do not like using do
blocks in SAS which is why I create logic describing a node's entire path. The single integer after the tuples is the ID of the terminal node in a path. All of the preceding tuples combine to create that node.
In [1]: get_lineage(dt, df.columns)
(0, 'l', 0.5, 'col1')
1
(0, 'r', 0.5, 'col1')
(2, 'l', 4.5, 'col2')
3
(0, 'r', 0.5, 'col1')
(2, 'r', 4.5, 'col2')
(4, 'l', 2.5, 'col1')
5
(0, 'r', 0.5, 'col1')
(2, 'r', 4.5, 'col2')
(4, 'r', 2.5, 'col1')

The ideal way to do it will be using "INSERT OVERWRITE DIRECTORY '/pathtofile' select * from temp where id > 100" instead of "hive -e 'select * from...' > /filepath.txt"
To skip .
& ..
, you can use Dir::each_child
.
Dir.each_child('/path/to/dir') do |filename|
puts filename
end
Dir::children
returns an array of the filenames.
Convert your UTC date to Local Date
-(NSString *)getLocalDateTimeFromUTC:(NSString *)strDate
{
NSDateFormatter *dtFormat = [[NSDateFormatter alloc] init];
[dtFormat setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
[dtFormat setTimeZone:[NSTimeZone timeZoneWithAbbreviation:@"UTC"]];
NSDate *aDate = [dtFormat dateFromString:strDate];
[dtFormat setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
[dtFormat setTimeZone:[NSTimeZone systemTimeZone]];
return [dtFormat stringFromDate:aDate];
}
Use Like This
NSString *localDate = [self getLocalDateTimeFromUTC:@"yourUTCDate"];
Use XmlDocument.Load()
method to load XML from your file. Then use XmlDocument.InnerXml

XmlDocument doc = new XmlDocument();
doc.Load("path to your file");
string xmlcontents = doc.InnerXml;
I know this is a super old post, but I think what is missed is overriding __repr__

I like to do the following if running in a script where the function is defined:
POINTER= # used for function return values
my_function() {
# do stuff
POINTER="my_function_return"
}
my_other_function() {
# do stuff
POINTER="my_other_function_return"
}
my_function
RESULT="$POINTER"
my_other_function
RESULT="$POINTER"
I like this, becase I can then include echo statements in my functions if I want
my_function() {
echo "-> my_function()"
# do stuff
POINTER="my_function_return"
echo "<- my_function. $POINTER"
}
hope this helps someone:

In case, you would like to collect bitstamp trade data form their websocket in higher resolution over longer time period you could use script log_bitstamp_trades.py below.

At the top level menus, select 'Search' -> 'File Search' Then near the bottom (in the scope) there is a choice to select the entire workspace.
For your "File search has encountered a problem", you need to refresh the files in your workspace, in the Project/Package Explorer, right click and select "Refresh" at any level (project, folder, file). This will sync your workspace with the underlying file system and prevent the problem.

The answer for Ashwini is great, in pointing out that scipy.math.factorial
, numpy.math.factorial
, math.factorial
are the same functions. However, I'd recommend use the one that Janne mentioned, that scipy.special.factorial
is different. The one from scipy can take np.ndarray
as an input, while the others can't.
In [12]: import scipy.special
In [13]: temp = np.arange(10) # temp is an np.ndarray
In [14]: math.factorial(temp) # This won't work
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
<ipython-input-14-039ec0734458> in <module>()
----> 1 math.factorial(temp)
TypeError: only length-1 arrays can be converted to Python scalars
In [15]: scipy.special.factorial(temp) # This works!
Out[15]:
array([ 1.00000000e+00, 1.00000000e+00, 2.00000000e+00,
6.00000000e+00, 2.40000000e+01, 1.20000000e+02,
7.20000000e+02, 5.04000000e+03, 4.03200000e+04,
3.62880000e+05])
So, if you are doing factorial to a np.ndarray, the one from scipy will be easier to code and faster than doing the for-loops.

Grinn solution is great.
However it doesn't work for me when there are parent folder relative references in the url.
i.e. url('../../images/car.png')
So, I slightly changed the Include
method in order to resolve the paths for each regex match, allowing relative paths and also to optionally embed the images in the css.
I also changed the IF DEBUG to check BundleTable.EnableOptimizations
instead of HttpContext.Current.IsDebuggingEnabled
.
public new Bundle Include(params string[] virtualPaths)
{
if (!BundleTable.EnableOptimizations)
{
// Debugging. Bundling will not occur so act normal and no one gets hurt.
base.Include(virtualPaths.ToArray());
return this;
}
var bundlePaths = new List<string>();
var server = HttpContext.Current.Server;
var pattern = new Regex(@"url\s*\(\s*([""']?)([^:)]+)\1\s*\)", RegexOptions.IgnoreCase);
foreach (var path in virtualPaths)
{
var contents = File.ReadAllText(server.MapPath(path));
var matches = pattern.Matches(contents);
// Ignore the file if no matches
if (matches.Count == 0)
{
bundlePaths.Add(path);
continue;
}
var bundlePath = (System.IO.Path.GetDirectoryName(path) ?? string.Empty).Replace(@"\", "/") + "/";
var bundleUrlPath = VirtualPathUtility.ToAbsolute(bundlePath);
var bundleFilePath = string.Format("{0}{1}.bundle{2}",
bundlePath,
System.IO.Path.GetFileNameWithoutExtension(path),
System.IO.Path.GetExtension(path));
// Transform the url (works with relative path to parent folder "../")
contents = pattern.Replace(contents, m =>
{
var relativeUrl = m.Groups[2].Value;
var urlReplace = GetUrlReplace(bundleUrlPath, relativeUrl, server);
return string.Format("url({0}{1}{0})", m.Groups[1].Value, urlReplace);
});
File.WriteAllText(server.MapPath(bundleFilePath), contents);
bundlePaths.Add(bundleFilePath);
}
base.Include(bundlePaths.ToArray());
return this;
}
private string GetUrlReplace(string bundleUrlPath, string relativeUrl, HttpServerUtility server)
{
// Return the absolute uri
Uri baseUri = new Uri("http://dummy.org");
var absoluteUrl = new Uri(new Uri(baseUri, bundleUrlPath), relativeUrl).AbsolutePath;
var localPath = server.MapPath(absoluteUrl);
if (IsEmbedEnabled && File.Exists(localPath))
{
var fi = new FileInfo(localPath);
if (fi.Length < 0x4000)
{
// Embed the image in uri
string contentType = GetContentType(fi.Extension);
if (null != contentType)
{
var base64 = Convert.ToBase64String(File.ReadAllBytes(localPath));
// Return the serialized image
return string.Format("data:{0};base64,{1}", contentType, base64);
}
}
}
// Return the absolute uri
return absoluteUrl;
}
Hope it helps, regards.
I got the solution by using comm
comm -23 file1 file2
will give you the desired output.
The files need to be sorted first anyway.
Your problem is that when you do this:
a = Button(win, text="plant", command=setText("plant"))
it tries to evaluate what to set for the command. So when instantiating the Button
object, it actually calls setText("plant")
. This is wrong, because you don't want to call the setText method yet. Then it takes the return value of this call (which is None
), and sets that to the command of the button. That's why clicking the button does nothing, because there is no command set for it.
If you do as Milan Skála suggested and use a lambda expression instead, then your code will work (assuming you fix the indentation and the parentheses).
Instead of command=setText("plant")
, which actually calls the function, you can set command=lambda:setText("plant")
which specifies something which will call the function later, when you want to call it.
If you don't like lambdas, another (slightly more cumbersome) way would be to define a pair of functions to do what you want:
def set_to_plant():
set_text("plant")
def set_to_animal():
set_text("animal")
and then you can use command=set_to_plant
and command=set_to_animal
- these will evaluate to the corresponding functions, but are definitely not the same as command=set_to_plant()
which would of course evaluate to None
again.
For Python3 it is required to use BytesIO:
from io import BytesIO
from PIL import Image, ImageDraw
image = Image.new("RGB", (300, 50))
draw = ImageDraw.Draw(image)
draw.text((0, 0), "This text is drawn on image")
byte_io = BytesIO()
image.save(byte_io, 'PNG')

Here is the Swift 5 version:
let delegate = UIApplication.shared.delegate as? AppDelegate
And to access the managed object context:
if let delegate = UIApplication.shared.delegate as? AppDelegate {
let moc = delegate.managedObjectContext
// your code here
}
or, using guard:
guard let delegate = UIApplication.shared.delegate as? AppDelegate else {
return
}
let moc = delegate.managedObjectContext
// your code here
The most trivial way to upload a binary file to an FTP server using PowerShell is using WebClient.UploadFile
:
$client = New-Object System.Net.WebClient
$client.Credentials = New-Object System.Net.NetworkCredential("username", "password")
$client.UploadFile("ftp://ftp.example.com/remote/path/file.zip", "C:\local\path\file.zip")
If you need a greater control, that WebClient
does not offer (like TLS/SSL encryption, etc), use FtpWebRequest
. Easy way is to just copy a FileStream
to FTP stream using Stream.CopyTo
:
$request = [Net.WebRequest]::Create("ftp://ftp.example.com/remote/path/file.zip")
$request.Credentials = New-Object System.Net.NetworkCredential("username", "password")
$request.Method = [System.Net.WebRequestMethods+Ftp]::UploadFile
$fileStream = [System.IO.File]::OpenRead("C:\local\path\file.zip")
$ftpStream = $request.GetRequestStream()
$fileStream.CopyTo($ftpStream)
$ftpStream.Dispose()
$fileStream.Dispose()
If you need to monitor an upload progress, you have to copy the contents by chunks yourself:
$request = [Net.WebRequest]::Create("ftp://ftp.example.com/remote/path/file.zip")
$request.Credentials = New-Object System.Net.NetworkCredential("username", "password")
$request.Method = [System.Net.WebRequestMethods+Ftp]::UploadFile
$fileStream = [System.IO.File]::OpenRead("C:\local\path\file.zip")
$ftpStream = $request.GetRequestStream()
$buffer = New-Object Byte[] 10240
while (($read = $fileStream.Read($buffer, 0, $buffer.Length)) -gt 0)
{
$ftpStream.Write($buffer, 0, $read)
$pct = ($fileStream.Position / $fileStream.Length)
Write-Progress `
-Activity "Uploading" -Status ("{0:P0} complete:" -f $pct) `
-PercentComplete ($pct * 100)
}
$ftpStream.Dispose()
$fileStream.Dispose()
If you want to upload all files from a folder, see
PowerShell Script to upload an entire folder to FTP
Yes, you can call setId(value)
in any view with any (positive) integer value that you like and then find it in the parent container using findViewById(value)
. Note that it is valid to call setId()
with the same value for different sibling views, but findViewById()
will return only the first one.
I'm using tidy together with custom build system to prettify HTML.
I have HTMLTidy.sublime-build in my Packages/User/ directory:
{
"cmd": ["tidy", "-config", "$packages/User/tidy_config.cfg", "$file"]
}
and tidy_config.cfg file in the same directory:
indent: auto
tab-size: 4
show-warnings: no
write-back: yes
quiet: yes
indent-cdata: yes
tidy-mark: no
wrap: 0
And just select build system and press ctrl+b or cmd+b to reformat file content. One minor issue with that is that ST2 does not automatically reload the file so to see the results you have to switch to some other file and back (or to other application and back).
On Mac I've used macports to install tidy, on Windows you'd have to download it yourself and specify working directory in the build system, where tidy is located:
"working_dir": "c:\\HTMLTidy\\"
or add it to the PATH.
you cant do this. Use a custom popup. Something like with the help of jQuery UI or jQuery BOXY.
for jQuery UI http://jqueryui.com/demos/dialog/
for jQuery BOXY http://onehackoranother.com/projects/jquery/boxy/
ReducedForm
is a type, so you cannot say
ReducedForm.iSimplifiedNumerator = iNumerator/iGreatCommDivisor;
You can only use the .
operator on an instance:
ReducedForm rf;
rf.iSimplifiedNumerator = iNumerator/iGreatCommDivisor;
Try getWindow().getDecorView().findViewById(android.R.id.content).invalidate();
Running JMeter in command line mode:
1.Navigate to JMeter’s bin directory
Now enter following command,
jmeter -n –t test.jmx
-n: specifies JMeter is to run in non-gui mode
-t: specifies name of JMX file that contains the Test Plan
The second option is completely fine. I'm not sure why a responder said it was not possible. This is fine, and I do this all the time:
switch (variable)
{
case 5:
case 6:
etc.
case 100:
doSomething();
break;
}
Use transform: rotate(90deg)
:
#container_2 {_x000D_
border: 1px solid;_x000D_
padding: .5em;_x000D_
width: 5em;_x000D_
height: 5em;_x000D_
transition: .3s all; /* rotate gradually instead of instantly */_x000D_
}_x000D_
_x000D_
#container_2:hover {_x000D_
-webkit-transform: rotate(90deg); /* to support Safari and Android browser */_x000D_
-ms-transform: rotate(90deg); /* to support IE 9 */_x000D_
transform: rotate(90deg);_x000D_
}
_x000D_
<div id="container_2">This box should be rotated 90° on hover.</div>
_x000D_
Click "Run code snippet", then hover over the box to see the effect of the transform.
Realistically, no other prefixed entries are needed. See Can I use CSS3 Transforms?
Another alternate approach to Diego's is to use a library:
https://github.com/airbnb/DeepLinkDispatch
You can easily declare the URIs you'd like to handle and the parameters you'd like to extract through annotations on the Activity, like:
@DeepLink("path/to/what/i/want")
public class SomeActivity extends Activity {
...
}
As a plus, the query parameters will also be passed along to the Activity as well.
Another option is to repeat the rules in two prefix locations using an included file. Since prefix locations are position independent in the configuration, using them can save some confusion as you add other regex locations later on. Avoiding regex locations when you can will help your configuration scale smoothly.
server {
location /first/location/ {
include shared.conf;
}
location /second/location/ {
include shared.conf;
}
}
Here's a sample shared.conf:
default_type text/plain;
return 200 "http_user_agent: $http_user_agent
remote_addr: $remote_addr
remote_port: $remote_port
scheme: $scheme
nginx_version: $nginx_version
";
In HTML, SGML and XML, (1) attributes cannot be repeated, and should only be defined in an element once.
So your example:
<span style="color:blue" style="font-style:italic">Test</span>
is non-conformant to the HTML standard, and will result in undefined behaviour, which explains why different browsers are rendering it differently.
Since there is no defined way to interpret this, browsers can interpret it however they want and merge them, or ignore them as they wish.
(1): Every article I can find states that attributes are "key/value" pairs or "attribute-value" pairs, heavily implying the keys must be unique. The best source I can find states:
Attribute names (id and status in this example) are subject to the same restrictions as other names in XML; they need not be unique across the whole DTD, however, but only within the list of attributes for a given element. (Emphasis mine.)
I Found the esiest soltuion just wrap the button with div and put text-center align-items-center in it like this :
<div text-center align-items-center>
<buttonion-button block class="button-design " text-center>Sign In </button>
</div>
Properties in your object are value types and you can use the shallow copy in such situation like that:
obj myobj2 = (obj)myobj.MemberwiseClone();
But in other situations, like if any members are reference types, then you need Deep Copy. You can get a deep copy of an object using Serialization
and Deserialization
techniques with the help of BinaryFormatter
class:
public static T DeepCopy<T>(T other)
{
using (MemoryStream ms = new MemoryStream())
{
BinaryFormatter formatter = new BinaryFormatter();
formatter.Context = new StreamingContext(StreamingContextStates.Clone);
formatter.Serialize(ms, other);
ms.Position = 0;
return (T)formatter.Deserialize(ms);
}
}
The purpose of setting StreamingContext
:
We can introduce special serialization and deserialization logic to our code with the help of either implementing ISerializable
interface or using built-in attributes like OnDeserialized
, OnDeserializing
, OnSerializing
, OnSerialized
. In all cases StreamingContext
will be passed as an argument to the methods(and to the special constructor in case of ISerializable
interface). With setting ContextState
to Clone
, we are just giving hint to that method about the purpose of the serialization.
Additional Info: (you can also read this article from MSDN)
Shallow copying is creating a new object and then copying the nonstatic fields of the current object to the new object. If a field is a value type, a bit-by-bit copy of the field is performed; for a reference type, the reference is copied but the referred object is not; therefore the original object and its clone refer to the same object.
Deep copy is creating a new object and then copying the nonstatic fields of the current object to the new object. If a field is a value type, a bit-by-bit copy of the field is performed. If a field is a reference type, a new copy of the referred object is performed.
To add to the other answers, a common use case I have found for setattr()
is when using configs. It is common to parse configs from a file (.ini file or whatever) into a dictionary. So you end up with something like:
configs = {'memory': 2.5, 'colour': 'red', 'charge': 0, ... }
If you want to then assign these configs to a class to be stored and passed around, you could do simple assignment:
MyClass.memory = configs['memory']
MyClass.colour = configs['colour']
MyClass.charge = configs['charge']
...
However, it is much easier and less verbose to loop over the configs, and setattr()
like so:
for name, val in configs.items():
setattr(MyClass, name, val)
As long as your dictionary keys have the proper names, this works very well and is nice and tidy.
*Note, the dict keys need to be strings as they will be the class object names.
I agree that it should not be used globally, but it's not so evil to use locally, like in a namespace
. Here's an example from "The C++ Programming Language":
namespace My_lib {
using namespace His_lib; // Everything from His_lib
using namespace Her_lib; // Everything from Her_lib
using His_lib::String; // Resolve potential clash in favor of His_lib
using Her_lib::Vector; // Resolve potential clash in favor of Her_lib
}
In this example, we resolved potential name clashes and ambiguities arising from their composition.
Names explicitly declared there (including names declared by using-declarations like His_lib::String
) take priority over names made accessible in another scope by a using-directive (using namespace Her_lib
).
To add to Lauritz's answer, I created a decorator/wrapper for exception handling and the wrapper logs which type of exception occurred.
class general_function_handler(object):
def __init__(self, func):
self.func = func
def __get__(self, obj, type=None):
return self.__class__(self.func.__get__(obj, type))
def __call__(self, *args, **kwargs):
try:
retval = self.func(*args, **kwargs)
except Exception, e :
logging.warning('Exception in %s' % self.func)
template = "An exception of type {0} occured. Arguments:\n{1!r}"
message = template.format(type(e).__name__, e.args)
logging.exception(message)
sys.exit(1) # exit on all exceptions for now
return retval
This can be called on a class method or a standalone function with the decorator:
@general_function_handler
See my blog about for the full example: http://ryaneirwin.wordpress.com/2014/05/31/python-decorators-and-exception-handling/
Does the second query return any results from the 17th, or just from the 18th?
The first query will only return results from the 17th, or midnight on the 18th.
Try this instead
select *
from LOGS
where check_in >= CONVERT(datetime,'2013-10-17')
and check_in< CONVERT(datetime,'2013-10-19')
On submitting, you would get an array as if created like this:
$_POST['topdiameter'] = array( 'first value', 'second value' );
$_POST['bottomdiameter'] = array( 'first value', 'second value' );
However, I would suggest changing your form names to this format instead:
name="diameters[0][top]"
name="diameters[0][bottom]"
name="diameters[1][top]"
name="diameters[1][bottom]"
...
Using that format, it's much easier to loop through the values.
if ( isset( $_POST['diameters'] ) )
{
echo '<table>';
foreach ( $_POST['diameters'] as $diam )
{
// here you have access to $diam['top'] and $diam['bottom']
echo '<tr>';
echo ' <td>', $diam['top'], '</td>';
echo ' <td>', $diam['bottom'], '</td>';
echo '</tr>';
}
echo '</table>';
}
when I send only one object from the client to server all works well.
when I attempt to send several objects one after another on the same stream I get
StreamCorruptedException
.
Actually, your client code is writing one object to the server and reading multiple objects from the server. And there is nothing on the server side that is writing the objects that the client is trying to read.
I guess the quickest way is just to disable the domain check while you're developing it
for ORA-01031: insufficient privileges. Some of the more common causes are:
UPDATE
to a table, but you only have SELECT
access to the table.CONNECT INTERNAL
.The option(s) to resolve this Oracle error are:
For ORA-00942: table or view does not exist.
You tried to execute a SQL statement that references a table or view that either does not exist, that you do not have access to, or that belongs to another schema and you didn't reference the table by the schema name.
If this error occurred because the table or view does not exist, you will need to create the table or view.
You can check to see if the table exists in Oracle by executing the following SQL statement:
select *
from all_objects
where object_type in ('TABLE','VIEW')
and object_name = 'OBJECT_NAME';
For example, if you are looking for a suppliers table, you would execute:
select *
from all_objects
where object_type in ('TABLE','VIEW')
and object_name = 'SUPPLIERS';
OPTION #2
If this error occurred because you do not have access to the table or view, you will need to have the owner of the table/view, or a DBA grant you the appropriate privileges to this object.
OPTION #3
If this error occurred because the table/view belongs to another schema and you didn't reference the table by the schema name, you will need to rewrite your SQL to include the schema name.
For example, you may have executed the following SQL statement:
select *
from suppliers;
But the suppliers
table is not owned by you, but rather, it is owned by a schema called app, you could fix your SQL as follows:
select *
from app.suppliers;
If you do not know what schema the suppliers table/view belongs to, you can execute the following SQL to find out:
select owner
from all_objects
where object_type in ('TABLE','VIEW')
and object_name = 'SUPPLIERS';
This will return the schema name who owns the suppliers table.
in EXCEL 2013 i had to use IF function 2 times: 1st to identify error with ISERROR and 2nd to identify the specific type of error by ERROR.TYPE=3 in order to address this type of error. This way you can differentiate between error you want and other types.
In my troubleshooting, I found this AJAX xmlhttpRequest.status == 0 could mean the client call had NOT reached the server yet, but failed due to issue on the client side. If the response was from server, then the status must be either those 1xx/2xx/3xx/4xx/5xx HTTP Response code. Henceforth, the troubleshooting shall focus on the CLIENT issue, and could be internet network connection down or one of those described by @Langdon above.
Given a date object:
date.getFullYear().toString().substr(2,2);
It returns the number as string. If you want it as integer just wrap it inside the parseInt() function:
var twoDigitsYear = parseInt(date.getFullYear().toString().substr(2,2), 10);
Example with the current year in one line:
var twoDigitsCurrentYear = parseInt(new Date().getFullYear().toString().substr(2,2));
This was my stupidity, but a stupidity that was not easy to identify :).
Problem:
If you are deploying manually into your server, ensure your JAVA_HOME, JDK_HOME points to the correct JDK which you used to compile the project and build the war.
If you do not like to change JAVA_HOME, JDK_HOME, you can always change the JAVA_HOME and JDK_HOME in catalina.bat(for tomcat server) and that'll enable your life to be easy!
Classic C (the early dialect of C described by Brian Kernighan and Dennis Ritchie in The C Programming Language, Prentice-Hall, 1978) didn't provide size_t

One can also use NumPy's flat:

This error is generic of the security libraries and might happen in other cases. In case other people have this same error when sending emails with javax.mail to a smtp server. Then the code to force other protocol is setting a property like this:
prop.put("mail.smtp.ssl.protocols", "TLSv1.2");
//And just in case probably you need to set these too
prop.put("mail.smtp.starttls.enable", true);
prop.put("mail.smtp.ssl.trust", {YOURSERVERNAME});
In the WPF application, you can handle this by handling TextChanged
event:
void arsDigitTextBox_TextChanged(object sender, System.Windows.Controls.TextChangedEventArgs e)
{
Regex regex = new Regex("[^0-9]+");
bool handle = regex.IsMatch(this.Text);
if (handle)
{
StringBuilder dd = new StringBuilder();
int i = -1;
int cursor = -1;
foreach (char item in this.Text)
{
i++;
if (char.IsDigit(item))
dd.Append(item);
else if(cursor == -1)
cursor = i;
}
this.Text = dd.ToString();
if (i == -1)
this.SelectionStart = this.Text.Length;
else
this.SelectionStart = cursor;
}
}
Another way for filtering the database with specific word.
SHOW DATABASES WHERE `Database` LIKE '<yourDatabasePrefixHere>%'
or
SHOW DATABASES LIKE '<yourDatabasePrefixHere>%';
Example:
SHOW DATABASES WHERE `Database` LIKE 'foobar%'
foobar_animal
foobar_humans_gender
foobar_objects
i think the easiest way is to use the Adobe PDF reader COM Component

I changed @Eli Bendersky's answer a little bit to use the ctor __init__()
and dtor __del__()
to do the timing, so that it can be used more conveniently without indenting the original code:
class Timer(object):
def __init__(self, name=None):
self.name = name
self.tstart = time.time()
def __del__(self):
if self.name:
print '%s elapsed: %.2fs' % (self.name, time.time() - self.tstart)
else:
print 'Elapsed: %.2fs' % (time.time() - self.tstart)
To use, simple put Timer("blahblah") at the beginning of some local scope. Elapsed time will be printed at the end of the scope:
for i in xrange(5):
timer = Timer("eigh()")
x = numpy.random.random((4000,4000));
x = (x+x.T)/2
numpy.linalg.eigh(x)
print i+1
timer = None
It prints out:
1
eigh() elapsed: 10.13s
2
eigh() elapsed: 9.74s
3
eigh() elapsed: 10.70s
4
eigh() elapsed: 10.25s
5
eigh() elapsed: 11.28s
You can add one of the Java path to PATH variable using the following command.
export PATH=$PATH:/usr/java/jre1.6.0_24/bin/
You can add this line to .bashrc file in your home directory. Adding this to .bashrc will ensure everytime you open bash it will be PATH variable is updated.
In my case, Web Sharing was running, which blocked XAMPP.
'Untick' Web Sharing in the Bluetooth Settings (or Network), which causes HTTPD to show in activity log.

Sounds to me you dn't want the mouse over events: you want the jQuery hover() event.
And what you seem to want is a "rich" tooltip, in which case I suggest jQuery tooltip. With the bodyHandler option you can put arbitrary HTML in.
Or, create a new table as temp with the extra column, copy the data to this new table while manipulating it as necessary to fill the non-nullable new column, and then swap the table via a two-step name change.
Yes, it is more complicated, but you may need to do it this way if you don't want a big UPDATE on a live table.
There is problem in name spacing as in laravel 5.2.3

model
class ApiModel extends Model

protected $table='tbl_users';
}

in you settings file, you also need ALLOWED_HOST list set up.
Try including ALLOWED_HOST = ['127.0.0.1', 'localhost', 'www.yourdomain.com']

I don't know the direct answer to your question, but if you do a lot of these scripts, it might be worth learning a more powerful language like perl. Free implementations exist for Windows (e.g. activestate, cygwin). I've found it worth the initial effort for my own tasks.
Edit:
As suggested by @Ferruccio, if you can't install extra software, consider vbscript and/or javascript. They're built into the Windows scripting host.
Question: How can I open the href in the new window or tab with jQuery?
var url = $(this).attr('href').attr('target','_blank');
If including a library is overkill here is a solution that is guaranteed to work.
$('div').click(function() {
$(this).css('background-color','#FFFFCC');
setTimeout(function() { $(this).fadeOut('slow').fadeIn('slow'); } , 1000);
setTimeout(function() { $(this).css('background-color','#FFFFFF'); } , 1000);
});
Setup event trigger
Set the background color of block element
Inside setTimeout use fadeOut and fadeIn to create a little animation effect.
Inside second setTimeout reset default background color
Tested in a few browsers and it works nicely.
A good example given in book: Practical Python By Magnus Lie Hetland
>>> zip(range(5), xrange(100000000))
[(0, 0), (1, 1), (2, 2), (3, 3), (4, 4)]
I wouldn’t recommend using range instead of xrange in the preceding example—although only the first five numbers are needed, range calculates all the numbers, and that may take a lot of time. With xrange, this isn’t a problem because it calculates only those numbers needed.
Yes I read @Brian's answer: In python 3, range() is a generator anyway and xrange() does not exist.
assuming the item numbers are unique, a VLOOKUP
should get you the information you need.
first value would be =VLOOKUP(E1,A:B,2,FALSE)
, and the same type of formula to retrieve the second value would be =VLOOKUP(E1,C:D,2,FALSE)
. Wrap them in an IFERROR
if you want to return anything other than #N/A if there is no corresponding value in the item column(s)
In order to do this your JavaScript file would need to be pre-processed on the server side. Essentially, it would have to become an ASP.NET View of some kind, and script
tags which reference the file would essentially be referencing a controller action which responds with that view.
That sounds like a can of worms you don't want to open.
Since JavaScript is client-side, why not just set the value to some client-side element and have the JavaScript interact with that. It's perhaps an additional step of indirection, but it sounds like much less of a headache than creating a JavaScript view.
Something like this:
<script type="text/javascript">
var someValue = @ViewBag.someValue
</script>
Then the external JavaScript file can reference the someValue
JavaScript variable within the scope of that document.
Or even:
<input type="hidden" id="someValue" value="@ViewBag.someValue" />
Then you can access that hidden input.
Unless you come up with some really slick way to actually make your JavaScript file usable as a view. It's certainly doable, and I can't readily think of any problems you'd have (other than really ugly view code since the view engine will get very confused as to what's JavaScript and what's Razor... so expect a ton of <text>
markup), so if you find a slick way to do it that would be pretty cool, albeit perhaps unintuitive to someone who needs to support the code later.
I like the #define
way of doing this:
// Place this in your .h file, outside the @interface block
typedef enum {
JPG,
PNG,
GIF,
PVR
} kImageType;
#define kImageTypeArray @"JPEG", @"PNG", @"GIF", @"PowerVR", nil
// Place this in the .m file, inside the @implementation block
// A method to convert an enum to string
-(NSString*) imageTypeEnumToString:(kImageType)enumVal
{
NSArray *imageTypeArray = [[NSArray alloc] initWithObjects:kImageTypeArray];
return [imageTypeArray objectAtIndex:enumVal];
}
source (source no longer available)
That's because your input string can’t be converted according to the encoding rules (strict by default).
I don't know, but I always encoded using directly unicode() constructor, at least that's the ways at the official documentation:
unicode(your_str, errors="ignore")
System Preferences => Keyboard => Key Repeat Rate
Regexes can also limit the number of characters.
r = re.compile("^[a-z]{1,15}$")
gives you a regex that only matches if the input is entirely lowercase ASCII letters and 1 to 15 characters long.
Here I have a CSS-selector based on bobince's answer to select any focusable HTML element:
a[href]:not([tabindex='-1']),
area[href]:not([tabindex='-1']),
input:not([disabled]):not([tabindex='-1']),
select:not([disabled]):not([tabindex='-1']),
textarea:not([disabled]):not([tabindex='-1']),
button:not([disabled]):not([tabindex='-1']),
iframe:not([tabindex='-1']),
[tabindex]:not([tabindex='-1']),
[contentEditable=true]:not([tabindex='-1'])
{
/* your CSS for focusable elements goes here */
}
or a little more beautiful in SASS:
a[href],
area[href],
input:not([disabled]),
select:not([disabled]),
textarea:not([disabled]),
button:not([disabled]),
iframe,
[tabindex],
[contentEditable=true]
{
&:not([tabindex='-1'])
{
/* your SCSS for focusable elements goes here */
}
}
I've added it as an answer, because that was, what I was looking for, when Google redirected me to this Stackoverflow question.
EDIT: There is one more selector, which is focusable:
[contentEditable=true]
However, this is used very rarely.
Check out Reuxables although it comes at a cost.

It looks to me like the background images aren't actually background images...the site has the background images and the quotes in sibling divs with the children of the div containing the images having been assigned position: fixed; The quotes div is also given a transparent background.

div for individual image{ <--- Fixed position
image <--- relative position
}
}
quote wrapper div{
div for individual quote{

}
}

Try compiling your .NET assembly with the option --staticlink:"Namespace.Assembly"
. This forces the compiler to pull in all the dependencies at compile time. If it comes across a dependency that's not referenced it will give a warning or error message usually with the name of that assembly.
Namespace.Assembly
is the assembly you suspect as having the dependency problem. Typically just statically linking this assembly will reference all dependencies transitively.
var s = ",'first string','more','even more'";
var array = s.split(',').slice(1);
That's assuming the string you begin with is in fact a String, like you said, and not an Array of strings.
I found that these instructions were not enough. I also had to search through the code files for models, controllers, and views as well as the AppStart files to change the namespace.
Since I was copying my project not just renaming it, I also had to go into the applicationhost.config for IIS express and recreate the bindings using different port numbers and change the physical directory as well.
Depending on your project, you might want to consider using EditorConfig (https://editorconfig.org/). There's a Notepad++ plugin which will load an .editorconfig where you can specify "lf" as the mandatory line ending.
I've only started using it, but it's nice so far, and open source projects I've worked on have included .editorconfig files for years. The "EOL Conversion" setting isn't changed, so it can be a bit confusing, but if you "View > Show Symbol > Show End of Line", you can see that it's adding LF instead of CRLF, even when "EOL Conversion" and the lower bottom corner shows something else (e.g. Windows (CR LF)).
You do see for loops alot of the time, but they are usually not needed. Here is an example of how one might perform a for loop without resorting to the shell
LIST_OF_THINGS_TO_DO = do_this do_that
$(LIST_OF_THINGS_TO_DO):
run $@ > [email protected]
SUBDIRS = snafu fubar
$(SUBDIRS):
cd $@ && $(MAKE)
It depends on whether default path is set for data and log files or not.
If the path is set explicitly at Properties
=> Database Settings
=> Database default locations
then SQL server stores it at Software\Microsoft\MSSQLServer\MSSQLServer
in DefaultData
and DefaultLog
values.
However, if these parameters aren't set explicitly, SQL server uses Data and Log paths of master database.
Bellow is the script that covers both cases. This is simplified version of the query that SQL Management Studio runs.
Also, note that I use xp_instance_regread
instead of xp_regread
, so this script will work for any instance, default or named.
declare @DefaultData nvarchar(512)
exec master.dbo.xp_instance_regread N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer', N'DefaultData', @DefaultData output
declare @DefaultLog nvarchar(512)
exec master.dbo.xp_instance_regread N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer', N'DefaultLog', @DefaultLog output
declare @DefaultBackup nvarchar(512)
exec master.dbo.xp_instance_regread N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer', N'BackupDirectory', @DefaultBackup output
declare @MasterData nvarchar(512)
exec master.dbo.xp_instance_regread N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer\Parameters', N'SqlArg0', @MasterData output
select @MasterData=substring(@MasterData, 3, 255)
select @MasterData=substring(@MasterData, 1, len(@MasterData) - charindex('\', reverse(@MasterData)))
declare @MasterLog nvarchar(512)
exec master.dbo.xp_instance_regread N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer\Parameters', N'SqlArg2', @MasterLog output
select @MasterLog=substring(@MasterLog, 3, 255)
select @MasterLog=substring(@MasterLog, 1, len(@MasterLog) - charindex('\', reverse(@MasterLog)))
select
isnull(@DefaultData, @MasterData) DefaultData,
isnull(@DefaultLog, @MasterLog) DefaultLog,
isnull(@DefaultBackup, @MasterLog) DefaultBackup
You can achieve the same result by using SMO. Bellow is C# sample, but you can use any other .NET language or PowerShell.
using (var connection = new SqlConnection("Data Source=.;Integrated Security=SSPI"))
{
var serverConnection = new ServerConnection(connection);
var server = new Server(serverConnection);
var defaultDataPath = string.IsNullOrEmpty(server.Settings.DefaultFile) ? server.MasterDBPath : server.Settings.DefaultFile;
var defaultLogPath = string.IsNullOrEmpty(server.Settings.DefaultLog) ? server.MasterDBLogPath : server.Settings.DefaultLog;
}
It is so much simpler in SQL Server 2012 and above, assuming you have default paths set (which is probably always a right thing to do):
select
InstanceDefaultDataPath = serverproperty('InstanceDefaultDataPath'),
InstanceDefaultLogPath = serverproperty('InstanceDefaultLogPath')
Normally, When you copy a cell you will find the below statement written down in the status bar (in the bottom of your sheet)
"Select destination and Press Enter or Choose Paste"
Then you press whether Enter or choose paste to paste the value of the cell.
If you didn't press Esc afterwards you will be able to paste the value of the cell several times
Application.CutCopyMode = False does the same like the Esc button, if you removed it from your code you will find that you are able to paste the cell value several times again.
And if you closed the Excel without pressing Esc you will get the warning 'There is a large amount of information on the Clipboard....'
I had this same issue going from e.g gcc to visual studio for C programming. Make sure your include file is actually in the directory -- not just shown in the VS project tree. For me in other languages copying into a folder in the project tree would indeed move the file in. With Visual Studio 2010, pasting into "Header Files" was NOT putting the .h file there.
Please check your actual directory for the presence of the include file. Putting it into the "header files" folder in project/solution explorer was not enough.
request
is now deprecated. It is recommended you use an alternativeIn no particular order and dreadfully incomplete:
const https = require('https');
Stats comparision Some code examples
This gets a lot easier if you use the request library.
var request = require('request');
request.post(
'http://www.yoursite.com/formpage',
{ json: { key: 'value' } },
function (error, response, body) {
if (!error && response.statusCode == 200) {
console.log(body);

Aside from providing a nice syntax it makes json requests easy, handles oauth signing (for twitter, etc.), can do multi-part forms (e.g. for uploading files) and streaming.

• real: The actual time spent in running the process from start to finish, as if it was measured by a human with a stopwatch
• user: The cumulative time spent by all the CPUs during the computation
• sys: The cumulative time spent by all the CPUs during system-related tasks such as memory allocation.
Notice that sometimes user + sys might be greater than real, as multiple processors may work in parallel.
From this page:
Make oldconfig takes the .config and runs it through the rules of the Kconfig files and produces a .config which is consistant with the Kconfig rules. If there are CONFIG values which are missing, the make oldconfig will ask for them.
If the .config is already consistant with the rules found in Kconfig, then make oldconfig is essentially a no-op.
If you were to run make oldconfig, and then run make oldconfig a second time, the second time won't cause any additional changes to be made.
You can use StringBuffer
or StringBuilder
for this. Both are for dynamic string manipulation. StringBuffer
is thread-safe where as StringBuilder
is not.
Use StringBuffer
in a multi-thread environment. But if it is single threaded StringBuilder
is recommended and it is much faster than StringBuffer
.
Any Java developer can easily become an expert ANT user, but not even an expert Java developer can't become a beginner level MAVEN user.
Maven will make your developers scared s***less for doing anything related to Build and Deployment.
They will start respecting Maven more than the War file or Ear file!! which is bad bad bad!
Then you will be left at the mercy of online forums, where fan-boys will berate you for not doing things the "Maven way".
You can store objects in a HashMap.
HashMap<String, Object> map = new HashMap<String, Object>();
You'll just need to cast it back out correctly.
Here are some examples from this blog mentioned earlier:
<configuration>
<Database>
<add key="ConnectionString" value="data source=.;initial catalog=NorthWind;integrated security=SSPI"/>
</Database>
</configuration>
get values:
NameValueCollection db = (NameValueCollection)ConfigurationSettings.GetConfig("Database");
labelConnection2.Text = db["ConnectionString"];
-
Another example:
<Locations
ImportDirectory="C:\Import\Inbox"
ProcessedDirectory ="C:\Import\Processed"
RejectedDirectory ="C:\Import\Rejected"
/>
get value:
Hashtable loc = (Hashtable)ConfigurationSettings.GetConfig("Locations");
labelImport2.Text = loc["ImportDirectory"].ToString();
labelProcessed2.Text = loc["ProcessedDirectory"].ToString();

I wanted to use the perfect solution of @TheHippo in an anonymous function, without use of process and trigger functions. The following worked for me, sharing for novice programmers like myself.
(function traverse(o) {
for (var i in o) {
console.log('key : ' + i + ', value: ' + o[i]);
if (o[i] !== null && typeof(o[i])=="object") {
//going on step down in the object tree!!
traverse(o[i]);
}
}
})
(json);
Short answer: You can't. rm
removes files blindly, with no concept of 'trash'.
Some Unix and Linux systems try to limit its destructive ability by aliasing it to rm -i
by default, but not all do.
Long answer: Depending on your filesystem, disk activity, and how long ago the deletion occured, you may be able to recover some or all of what you deleted. If you're using an EXT3 or EXT4 formatted drive, you can check out extundelete

In the future, use rm
with caution. Either create a del
alias that provides interactivity, or use a file manager.
It's like the COM registry done right, with respect to the physical files as well as their interface and location information. In COM, files were everywhere, with centralised metadata. The GAC centralises the bang shoot.

You can simply delete the whole configuration folder ${user.home}/.IntelliJIdea60/config
while IntelliJ IDEA is not running. Next time it restarts, everything is restored from the default settings.
It depends on the OS:
To my surprise you do not need users-permission CONTACT_READ to read the names and some basic information (Is the contact starred, what was the last calling time). However you do need permission to read the details of the contact like phone number.
I found the following command to run from command line:
vlc.exe --extraintf=http:logger --verbose=2 --file-logging --logfile=vlc-log.txt
With the help of getter and setter, you can define a JavaScript class that does such a thing.
First, we define our class called MonitoredVariable
:
class MonitoredVariable {
constructor(initialValue) {
this._innerValue = initialValue;
this.beforeSet = (newValue, oldValue) => {};
this.beforeChange = (newValue, oldValue) => {};
this.afterChange = (newValue, oldValue) => {};
this.afterSet = (newValue, oldValue) => {};
}
set val(newValue) {
const oldValue = this._innerValue;
// newValue, oldValue may be the same
this.beforeSet(newValue, oldValue);
if (oldValue !== newValue) {
this.beforeChange(newValue, oldValue);
this._innerValue = newValue;
this.afterChange(newValue, oldValue);
}
// newValue, oldValue may be the same
this.afterSet(newValue, oldValue);
}
get val() {
return this._innerValue;
}
}
Assume that we want to listen for money
changes, let's create an instance of MonitoredVariable
with initial money 0
:
const money = new MonitoredVariable(0);
Then we could get or set its value using money.val
:
console.log(money.val); // Get its value
money.val = 2; // Set its value
Since we have not defined any listeners for it, nothing special happens after money.val
changes to 2.
Now let's define some listeners. We have four listeners available: beforeSet
, beforeChange
, afterChange
, afterSet
.
The following will happen sequentially when you use money.val = newValue
to change variable's value:
Now we define afterChange
listener which be triggered only after money.val
has changed (while afterSet
will be triggered even if the new value is the same as the old one):
money.afterChange = (newValue, oldValue) => {
console.log(`Money has been changed from ${oldValue} to ${newValue}`);
};
Now set a new value 3
and see what happens:
money.val = 3;
You will see the following in the console:
Money has been changed from 2 to 3

While the cursor: none
CSS solution is definitely a solid and easy workaround, if your actual goal is to remove the default cursor while your web application is being used, or implement your own interpretation of raw mouse movement (for FPS games, for example), you might want to consider using the Pointer Lock API instead.
You can use requestPointerLock on an element to remove the cursor, and redirect all mousemove
events to that element (which you may or may not handle):
document.body.requestPointerLock();
To release the lock, you can use exitPointerLock:
document.exitPointerLock();
No cursor, for real
This is a very powerful API call. It not only renders your cursor invisible, but it actually removes your operating system's native cursor. You won't be able to select text, or do anything with your mouse (except listening to some mouse events in your code) until the pointer lock is released (either by using exitPointerLock
or pressing ESC in some browsers).
That is, you cannot leave the window with your cursor for it to show again, as there is no cursor.
Restrictions
As mentioned above, this is a very powerful API call, and is thus only allowed to be made in response to some direct user-interaction on the web, such as a click; for example:
document.addEventListener("click", function () {
document.body.requestPointerLock();
});
Also, requestPointerLock
won't work from a sandboxed iframe
unless the allow-pointer-lock
permission is set.
User-notifications
Some browsers will prompt the user for a confirmation before the lock is engaged, some will simply display a message. This means pointer lock might not activate right away after the call. However, the actual activation of pointer locking can be listened to by listening to the pointerchange
event on the element on which requestPointerLock
was called:
document.body.addEventListener("pointerlockchange", function () {
if (document.pointerLockElement === document.body) {
// Pointer is now locked to <body>.
}
});
Most browsers will only display the message once, but Firefox will occasionally spam the message on every single call. AFAIK, this can only be worked around by user-settings, see Disable pointer-lock notification in Firefox.
Listening to raw mouse movement
The Pointer Lock API not only removes the mouse, but instead redirects raw mouse movement data to the element requestPointerLock
was called on. This can be listened to simply by using the mousemove
event, then accessing the movementX
and movementY
properties on the event object:
document.body.addEventListener("mousemove", function (e) {
console.log("Moved by " + e.movementX + ", " + e.movementY);
});
I know it's an old thread but this is something that I'm using and I thought it might help.
It works in python 2.7 and python 3< .

You can use 2 ways: int? or Nullable, both have the same behavior. You could to make a mix without problems but is better choice one to make code cleanest.
Option 1 (With ?):
private void Example(int? arg1, int? arg2)
{
if (arg1.HasValue)
{
//do something
}
if (arg1.HasValue)
{
//do something else
}
}
Option 2 (With Nullable):
private void Example(Nullable<int> arg1, Nullable<int> arg2)
{
if (arg1.HasValue)
{
//do something
}
if (arg1.HasValue)
{
//do something else
}
}
From C#4.0 comes a new way to do the same with more flexibility, in this case the framework offers optional parameters with default values, of this way you can set a default value if the method is called without all parameters.
Option 3 (With default values)
private void Example(int arg1 = 0, int arg2 = 1)
{
//do something else
}
You're searching for gc_maxlifetime, see http://php.net/manual/en/session.configuration.php#ini.session.gc-maxlifetime for a description.
Your session will last 1440 seconds which is 24 minutes (default).
