The folder is part of the URL you set when you create request
: "ftp://www.contoso.com/test.htm"
. If you use "ftp://www.contoso.com/wibble/test.htm"
then the file will be uploaded to a folder named wibble
.
You may need to first use a request with Method = WebRequestMethods.Ftp.MakeDirectory
to make the wibble
folder if it doesn't already exist.
If your pdf is text-based and not a scanned document (i.e. if you can click and drag to select text in your table in a PDF viewer), then you can use the module camelot-py
with
import camelot
tables = camelot.read_pdf('foo.pdf')
You then can choose how you want to save the tables (as csv, json, excel, html, sqlite), and whether the output should be compressed in a ZIP archive.
tables.export('foo.csv', f='csv', compress=False)
Edit: tabula-py
appears roughly 6 times faster than camelot-py
so that should be used instead.
import camelot
import cProfile
import pstats
import tabula
cmd_tabula = "tabula.read_pdf('table.pdf', pages='1', lattice=True)"
prof_tabula = cProfile.Profile().run(cmd_tabula)
time_tabula = pstats.Stats(prof_tabula).total_tt
cmd_camelot = "camelot.read_pdf('table.pdf', pages='1', flavor='lattice')"
prof_camelot = cProfile.Profile().run(cmd_camelot)
time_camelot = pstats.Stats(prof_camelot).total_tt
print(time_tabula, time_camelot, time_camelot/time_tabula)
gave

Well, what I do on every project is a mix of the options above.
First, add the jsr310 dependency:
<dependency>
<groupId>com.fasterxml.jackson.datatype</groupId>
<artifactId>jackson-datatype-jsr310</artifactId>
</dependency>
Important detail: put this dependency on the top of your depedencies list. I already see a project where the Localdate error persists even with this dependency on the pom.xml. But changing the order of the depedency the error was gone.
On your /src/main/resources/application.yml
file, setup the write-dates-as-timestamps
property:
spring:
jackson:
serialization:
write-dates-as-timestamps: false
And create a ObjectMapper
bean as this:
@Configuration
public class WebConfigurer {
@Bean
@Primary
public ObjectMapper objectMapper(Jackson2ObjectMapperBuilder builder) {
ObjectMapper objectMapper = builder.build();
objectMapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);
return objectMapper;
}
}
Following this configuration, the conversion always work on Spring Boot 1.5.x without any error.
Working with Spring AMQP, pay attention if you have a new instance of Jackson2JsonMessageConverter
(common thing when creating a SimpleRabbitListenerContainerFactory
). You need to pass the ObjectMapper
bean to it, like:
Jackson2JsonMessageConverter converter = new Jackson2JsonMessageConverter(objectMapper);
Otherwise, you will receive the same error.
It looks like the problem is request to server is not a multi-part request. Basically you need to modify your client-side form. For example:
<form action="..." method="post" enctype="multipart/form-data">
<input type="file" name="file" />
</form>
Hope this helps.
string urlParameters = "param1=value1¶m2=value2";
string _endPointName = "your url post api";
var httpWebRequest = (HttpWebRequest)WebRequest.Create(_endPointName);
httpWebRequest.ContentType = "application/x-www-form-urlencoded";
httpWebRequest.Method = "POST";
httpWebRequest.Headers["ContentType"] = "application/x-www-form-urlencoded";
System.Net.ServicePointManager.ServerCertificateValidationCallback +=
(se, cert, chain, sslerror) =>
{
return true;
};
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
streamWriter.Write(urlParameters);
streamWriter.Flush();
streamWriter.Close();
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
var result = streamReader.ReadToEnd();
}
There are two problems with your code:
LocalDateTime
does not support timezone. Given below is an overview of java.time types and you can see that the type which matches with your date-time string, 2016-12-01T23:00:00+00:00
is OffsetDateTime
because it has a zone offset of +00:00
.
Change your declaration as follows:
private OffsetDateTime startDate;
There are two problems with the format:
y
(year-of-era ) instead of Y
(week-based-year). Check this discussion to learn more about it. In fact, I recommend you use u
(year) instead of y
(year-of-era ). Check this answer for more details on it.XXX
or ZZZZZ
for the offset part i.e. your format should be uuuu-MM-dd'T'HH:m:ssXXX
.Check the documentation page of DateTimeFormatter
for more details about these symbols/formats.
Demo:
import java.time.OffsetDateTime;
import java.time.format.DateTimeFormatter;
public class Main {
public static void main(String[] args) {
String strDateTime = "2019-10-21T13:00:00+02:00";
DateTimeFormatter dtf = DateTimeFormatter.ofPattern("uuuu-MM-dd'T'HH:m:ssXXX");
OffsetDateTime odt = OffsetDateTime.parse(strDateTime, dtf);
System.out.println(odt);
}
}
Output:
2019-10-21T13:00+02:00

You can use @PropertySource
to externalize your configuration to a properties file. There is number of way to do get properties:
1.
Assign the property values to fields by using @Value
with PropertySourcesPlaceholderConfigurer
to resolve ${}
in @Value
:
@Configuration
@PropertySource("file:config.properties")
public class ApplicationConfiguration {
@Value("${gMapReportUrl}")
private String gMapReportUrl;
@Bean
public static PropertySourcesPlaceholderConfigurer propertyConfigInDev() {
return new PropertySourcesPlaceholderConfigurer();
}
}
2.
Get the property values by using Environment
:
@Configuration
@PropertySource("file:config.properties")
public class ApplicationConfiguration {
@Autowired
private Environment env;
public void foo() {
env.getProperty("gMapReportUrl");
}
}
Hope this can help
Issue resolved.!!! Below are the solutions.
For Java 6: Add below jars into {JAVA_HOME}/jre/lib/ext. 1. bcprov-ext-jdk15on-154.jar 2. bcprov-jdk15on-154.jar
Add property into {JAVA_HOME}/jre/lib/security/java.security security.provider.1=org.bouncycastle.jce.provider.BouncyCastleProvider
Java 7:download jar from below link and add to {JAVA_HOME}/jre/lib/security http://www.oracle.com/technetwork/java/javase/downloads/jce-7-download-432124.html
Java 8:download jar from below link and add to {JAVA_HOME}/jre/lib/security http://www.oracle.com/technetwork/java/javase/downloads/jce8-download-2133166.html
Issue is that it is failed to decrypt 256 bits of encryption.
For SDK 29 :
String str1 = "";
folder1 = new File(String.valueOf(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_MOVIES)));
if (folder1.exists()) {str1 = folder1.toString() + File.separator;}
public static void createTextFile(String sBody, String FileName, String Where) {
try {
File gpxfile = new File(Where, FileName);
FileWriter writer = new FileWriter(gpxfile);
writer.append(sBody);
writer.flush();
writer.close();
} catch (IOException e) {
e.printStackTrace();
}
}
Then you can save your file like this :
createTextFile("This is Content","file.txt",str1);
You need change url from https://android.googleapis.com/gcm/send to https://fcm.googleapis.com/fcm/send and change your app library too. this tutorial can help you https://firebase.google.com/docs/cloud-messaging/server#implementing-http-connection-server-protocol
You simply need to upgrade your Tomcat version, to Tomcat 8.0.xx. Java8 <-> Tomcat8
This is the configuration that I have been using and it has always worked out well
this did it for me. you can vary the options for the output format to Base64.Default whatsoever.
// encode base64 from image
ByteArrayOutputStream baos = new ByteArrayOutputStream();
imageBitmap.compress(Bitmap.CompressFormat.PNG, 100, baos);
byte[] b = baos.toByteArray();
encodedString = Base64.encodeToString(b, Base64.URL_SAFE | Base64.NO_WRAP);
You need to use following construction
InputStream in = getClass().getResourceAsStream("/yourFile");
Please note that you have to add this slash before your file name.
Newer versions of ARC(Advaced Rest client) also provides file upload option:
I want to share a simple approach for downloading files with JavaScript (ES6), React and a Spring Boot backend:
- Spring boot Rest Controller
Resource from org.springframework.core.io.Resource
@SneakyThrows
@GetMapping("/files/{filename:.+}/{extraVariable}")
@ResponseBody
public ResponseEntity<Resource> serveFile(@PathVariable String filename, @PathVariable String extraVariable) {
Resource file = storageService.loadAsResource(filename, extraVariable);
return ResponseEntity.ok()
.header(HttpHeaders.CONTENT_DISPOSITION, "attachment; filename=\"" + file.getFilename() + "\"")
.body(file);
}
- React, API call using AXIOS
Set the responseType to arraybuffer to specify the type of data contained in the response.
export const DownloadFile = (filename, extraVariable) => {
let url = 'http://localhost:8080/files/' + filename + '/' + extraVariable;
return axios.get(url, { responseType: 'arraybuffer' }).then((response) => {
return response;
})};
Final step > downloading
with the help of js-file-download you can trigger browser to save data to file as if it was downloaded.
DownloadFile('filename.extension', 'extraVariable').then(
(response) => {
fileDownload(response.data, filename);
}
, (error) => {
// ERROR
});
If you need to both get the raw content from the request, but also need to use a bound model version of it in the controller, you will likely get this exception.
NotSupportedException: Specified method is not supported.
For example, your controller might look like this, leaving you wondering why the solution above doesn't work for you:
public async Task<IActionResult> Index(WebhookRequest request)
{
using var reader = new StreamReader(HttpContext.Request.Body);
// this won't fix your string empty problems
// because exception will be thrown
reader.BaseStream.Seek(0, SeekOrigin.Begin);
var body = await reader.ReadToEndAsync();
// Do stuff
}
You'll need to take your model binding out of the method parameters, and manually bind yourself:
public async Task<IActionResult> Index()
{
using var reader = new StreamReader(HttpContext.Request.Body);
// You shouldn't need this line anymore.
// reader.BaseStream.Seek(0, SeekOrigin.Begin);
// You now have the body string raw
var body = await reader.ReadToEndAsync();
// As well as a bound model
var request = JsonConvert.DeserializeObject<WebhookRequest>(body);
}
It's easy to forget this, and I've solved this issue before in the past, but just now had to relearn the solution. Hopefully my answer here will be a good reminder for myself...
I was trying to write a code that would work on both Mac and Windows. The code was working fine on Windows, but was giving the response as 'Unsupported Media Type' on Mac. Here is the code I used and the following line made the code work on Mac as well:
Request.AddHeader "Content-Type", "application/json"
Here is the snippet of my code:
Dim Client As New WebClient
Dim Request As New WebRequest
Dim Response As WebResponse
Dim Distance As String
Client.BaseUrl = "http://1.1.1.1:8080/config"
Request.AddHeader "Content-Type", "application/json" *** The line that made the code work on mac
Set Response = Client.Execute(Request)
I used Retrofit 2.0 for my register users, send multipart/form File image and text from register account
In my RegisterActivity, use an AsyncTask
//AsyncTask
private class Register extends AsyncTask<String, Void, String> {
@Override
protected void onPreExecute() {..}
@Override
protected String doInBackground(String... params) {
new com.tequilasoft.mesasderegalos.dbo.Register().register(txtNombres, selectedImagePath, txtEmail, txtPassword);
responseMensaje = StaticValues.mensaje ;
mensajeCodigo = StaticValues.mensajeCodigo;
return String.valueOf(StaticValues.code);
}
@Override
protected void onPostExecute(String codeResult) {..}
And in my Register.java class is where use Retrofit with synchronous call
import android.util.Log;
import com.tequilasoft.mesasderegalos.interfaces.RegisterService;
import com.tequilasoft.mesasderegalos.utils.StaticValues;

// add another part within the multipart request
RequestBody requestEmail =
RequestBody.create(

// add another part within the multipart request
RequestBody requestPassword =
RequestBody.create(

// add another part within the multipart request
RequestBody requestNombres =
RequestBody.create(

MultipartBody.Part imagenPerfil = null;
if(selectedImagePath!=null){
File file = new File(selectedImagePath);
Log.i("Register","Nombre del archivo "+file.getName());
// create RequestBody instance from file
RequestBody requestFile =
RequestBody.create(MediaType.parse("multipart/form-data"), file);
// MultipartBody.Part is used to send also the actual file name
imagenPerfil = MultipartBody.Part.createFormData("imagenPerfil", file.getName(), requestFile);
}
// finally, execute the request
Call<ResponseBody> call = service.registerUser(imagenPerfil, requestEmail,requestPassword,requestNombres);
Response<ResponseBody> bodyResponse = call.execute();
StaticValues.code = bodyResponse.code();
StaticValues.mensaje = bodyResponse.message();
ResponseBody errorBody = bodyResponse.errorBody();
StaticValues.mensajeCodigo = errorBody==null
?null
:Utilities.mensajeCodigoDeLaRespuestaJSON(bodyResponse.errorBody().byteStream());
Log.i("Register","Code "+StaticValues.code);
Log.i("Register","mensaje "+StaticValues.mensaje);
Log.i("Register","mensajeCodigo "+StaticValues.mensaje);
}
catch (Exception e){
e.printStackTrace();
}
}
}
In the interface of RegisterService
public interface RegisterService {
@Multipart
@POST(StaticValues.REGISTER)
Call<ResponseBody> registerUser(@Part MultipartBody.Part image,
@Part("email") RequestBody email,
@Part("password") RequestBody password,
@Part("nombre") RequestBody nombre
);
}
For the Utilities parse ofr InputStream response
public class Utilities {
public static String mensajeCodigoDeLaRespuestaJSON(InputStream inputStream){
String mensajeCodigo = null;
try {
BufferedReader reader = new BufferedReader(
new InputStreamReader(
inputStream, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line;
while ((line = reader.readLine()) != null) {
sb.append(line).append("\n");
}
inputStream.close();
mensajeCodigo = sb.toString();
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
return mensajeCodigo;
}
}
It's not an array of arrays. It's an observable of observable(s).
The following returns an observable stream of string.
requestStream
.map(function(requestUrl) {
return requestUrl;
});
While this returns an observable stream of observable stream of json
requestStream
.map(function(requestUrl) {
return Rx.Observable.fromPromise(jQuery.getJSON(requestUrl));
});
flatMap
flattens the observable automatically for us so we can observe the json stream directly
If you use CMake you have to set WIN32 flag in add_executable
add_executable(${name} WIN32 ${source_files})
See CMake Doc for more information.
Enable TLs 1.2 from IE and add the following
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
Your command is completely incorrect. The output format is not rawvideo
and you don't need the bitstream filter h264_mp4toannexb
which is used when you want to convert the h264
contained in an mp4
to the Annex B
format used by MPEG-TS
for example. What you want to use instead is the aac_adtstoasc
for the AAC
streams.
ffmpeg -i http://.../playlist.m3u8 -c copy -bsf:a aac_adtstoasc output.mp4
Looks like problem of configuration for maven compiler in your pom file. Default version java source and target is 1.5, even used JDK has higher version.
To fix, add maven compiler plugin configuration section with higher java version, example:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.6.1</version>
<configuration>
<source>1.6</source>
<target>1.6</target>
</configuration>
</plugin>
For more info check these links:
Different file name which posted as "recfile" at <input type="file" name='recfile' placeholder="Select file"/>
and received as "file" at upload.single('file')
Solution : make sure both sent and received file are similar upload.single('recfile')
Another possible cause for this error message is if the HTTP Method is blocked by the server or load balancer.
It seems to be standard security practice to block unused HTTP Methods. We ran into this because HEAD was being blocked by the load balancer (but, oddly, not all of the load balanced servers, which caused it to fail only some of the time). I was able to test that the request itself worked fine by temporarily changing it to use the GET method.
The error code on iOS was: Error requesting App Code: Error Domain=NSURLErrorDomain Code=-1005 "The network connection was lost."
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
public class B3PassingExcelDataBase {
@Test()
//Import the data::row start at 3 and column at 1:
public static void imortingData () throws IOException {

XSSFWorkbook book=new XSSFWorkbook(file);
XSSFSheet sheet=book.getSheet("Sheet1");
int rowNum=sheet.getLastRowNum();
System.out.println(rowNum);
//get the row and value and assigned to variable to use in application
for (int r=3;r<rowNum;r++) {
// Rows stays same but column num changes and this is for only one person. It iterate for other.
XSSFRow currentRow=sheet.getRow(r);
String fName=currentRow.getCell(1).toString();
String lName=currentRow.getCell(2).toString();
String phone=currentRow.getCell(3).toString();
String email=currentRow.getCell(4).toString()
//passing the data
yogen.findElement(By.name("firstName")).sendKeys(fName); ;
yogen.findElement(By.name("lastName")).sendKeys(lName); ;
yogen.findElement(By.name("phone")).sendKeys(phone); ;
}
yogen.close();
}
}
Refer this:
@RequestMapping(value="download", method=RequestMethod.GET)
public void getDownload(HttpServletResponse response) {
// Get your file stream from wherever.
InputStream myStream = someClass.returnFile();
// Set the content type and attachment header.
response.addHeader("Content-disposition", "attachment;filename=myfilename.txt");
response.setContentType("txt/plain");
// Copy the stream to the response's output stream.
IOUtils.copy(myStream, response.getOutputStream());
response.flushBuffer();
}
To receive arbitrary Json in Spring-Boot, you can simply use Jackson's JsonNode
. The appropriate converter is automatically configured.
@PostMapping(value="/process")
public void process(@RequestBody com.fasterxml.jackson.databind.JsonNode payload) {
System.out.println(payload);
}
You are converting cert into BKS Keystore, why aren't you using .cert
directly, from https://developer.android.com/training/articles/security-ssl.html:
CertificateFactory cf = CertificateFactory.getInstance("X.509");
InputStream instream = context.getResources().openRawResource(R.raw.gtux_cert);
Certificate ca;
try {
ca = cf.generateCertificate(instream);
} finally {
caInput.close();
}
KeyStore kStore = KeyStore.getInstance(KeyStore.getDefaultType());
kStore.load(null, null);
kStore.setCertificateEntry("ca", ca);
TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm(););
tmf.init(kStore);
SSLContext context = SSLContext.getInstance("TLS");
context.init(null, tmf.getTrustManagers(), null);
okHttpClient.setSslSocketFactory(context.getSocketFactory());

The accepted answer didn't work in my situation, not sure why. I switched from JRE1.7 to JRE1.8 and that resolved the issue automatically. JRE1.8 uses TLS1.2 by default
Not the answer for this question
I got this exception when trying to delete a folder where i deleted the file inside.
Example:
createFolder("folder");
createFile("folder/file");
deleteFile("folder/file");
deleteFolder("folder"); // error here
While deleteFile("folder/file");
returned that it was deleted, the folder will only be considered empty after the program restart.
On some operating systems it may not be possible to remove a file when it is open and in use by this Java virtual machine or other programs.
https://docs.oracle.com/javase/8/docs/api/java/nio/file/Files.html#delete-java.nio.file.Path-
We have the following string which is a valid JSON ...
Clearly the JSON parser disagrees!
However, the exception says that the error is at "line 1: column 9", and there is no "http" token near the beginning of the JSON. So I suspect that the parser is trying to parse something different than this string when the error occurs.
You need to find what JSON is actually being parsed. Run the application within a debugger, set a breakpoint on the relevant constructor for JsonParseException
... then find out what is in the ByteArrayInputStream
that it is attempting to parse.
If you have config file transforms then ensure you have the correct config selected within your publish profile. (Publish > Settings > Configuration)
first,i used "localhost:port" format met this error.then I changed the address to "ip:port" format and the problem solved.
When I tried @PaulSamsotha's solution with Jersey client 2.21.1, there was 400 error. It worked when I added following in my client code:
MediaType contentType = MediaType.MULTIPART_FORM_DATA_TYPE;
contentType = Boundary.addBoundary(contentType);
Response response = t.request()
.post(Entity.entity(multipartEntity, contentType));
instead of hardcoded MediaType.MULTIPART_FORM_DATA
in POST request call.
The reason this is needed is because when you use a different Connector (like Apache) for the Jersey Client, it is unable to alter outbound headers, which is required to add a boundary to the Content-Type. This limitation is explained in the Jersey Client docs. So if you want to use a different Connector, then you need to manually create the boundary.
Simple and easy way to get File name
File file = new File("/storage/sdcard0/DCIM/Camera/1414240995236.jpg");
String strFileName = file.getName();
After add this code and print strFileName you will get strFileName = 1414240995236.jpg
A quick solution is add this code in your pom.xml:
<repositories>
<repository>
<id>central</id>
<name>Maven Plugin Repository</name>
<url>http://repo1.maven.org/maven2</url>
<layout>default</layout>
<snapshots>
<enabled>false</enabled>
</snapshots>
<releases>
<updatePolicy>never</updatePolicy>
</releases>
</repository>
</repositories>
Where never is for avoid the search a certified.
I face this problem but resolution is very simple. I am writing the 1 MB file in 1024 Byte Buffer causing this issue. To Understand refer code before and After Fix.
Code with Excepion
DataOutputStream dos = new DataOutputStream(s.getOutputStream());
FileInputStream fis = new FileInputStream(file);
byte[] buffer = new byte[1024];
while (fis.read(buffer) > 0) {
dos.write(buffer);
}
After Fixes:
DataOutputStream dos = new DataOutputStream(s.getOutputStream());
FileInputStream fis = new FileInputStream(file);
byte[] buffer = new byte[102400];
while (fis.read(buffer) > 0) {
dos.write(buffer);
}
Taking for granted that the JSON you posted is actually what you are seeing in the browser, then the problem is the JSON itself.
The JSON snippet you have posted is malformed.
You have posted:
[{
"name" : "shopqwe",
"mobiles" : [],
"address" : {
"town" : "city",
"street" : "streetqwe",
"streetNumber" : "59",
"cordX" : 2.229997,
"cordY" : 1.002539
},
"shoe"[{
"shoeName" : "addidas",
"number" : "631744030",
"producent" : "nike",
"price" : 999.0,
"sizes" : [30.0, 35.0, 38.0]
}]
while the correct JSON would be:
[{
"name" : "shopqwe",
"mobiles" : [],
"address" : {
"town" : "city",
"street" : "streetqwe",
"streetNumber" : "59",
"cordX" : 2.229997,
"cordY" : 1.002539
},
"shoe" : [{
"shoeName" : "addidas",
"number" : "631744030",
"producent" : "nike",
"price" : 999.0,
"sizes" : [30.0, 35.0, 38.0]
}
]
}
]
This is an easy way to get a successful response from the server like PHP echo otherwise an error message.
BufferedReader br = null;
if (conn.getResponseCode() == 200) {
br = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String strCurrentLine;
while ((strCurrentLine = br.readLine()) != null) {
System.out.println(strCurrentLine);
}
} else {
br = new BufferedReader(new InputStreamReader(conn.getErrorStream()));
String strCurrentLine;
while ((strCurrentLine = br.readLine()) != null) {
System.out.println(strCurrentLine);
}
}
If you want to avoid using an extra Class
and List<Object> genomes
you could simply use a Map
.
The data structure translates into Map<String, List<Country>>
String resourceEndpoint = "http://api.geonames.org/countryInfoJSON?username=volodiaL";
Map<String, List<Country>> geonames = restTemplate.getForObject(resourceEndpoint, Map.class);
List<Country> countries = geonames.get("geonames");
If you are using intellij, then try restarting intellij cache
See if it works, it worked for me.
Hi the problem is in FileDownloader class
urlConnection.setRequestMethod("GET");
urlConnection.setDoOutput(true);
You need to remove the above two lines and everything will work fine. Please mark the question as answered if it is working as expected.
Latest solution for the same problem is updated Android PDF Write / Read using Android 9 (API level 28)

As Artem Bilan said, this problem occures because MappingJackson2HttpMessageConverter
supports response with application/json content-type only. If you can't change server code, but can change client code(I had such case), you can change content-type header with interceptor:
restTemplate.getInterceptors().add((request, body, execution) -> {
ClientHttpResponse response = execution.execute(request,body);
response.getHeaders().setContentType(MediaType.APPLICATION_JSON);
return response;
});
You have to call close()
on the GZIPOutputStream
before you attempt to read it. The final bytes of the file will only be written when the file is actually closed. (This is irrespective of any explicit buffering in the output stack. The stream only knows to compress and write the last bytes when you tell it to close. A flush()
probably won't help ... though calling finish()
instead of close()
should work. Look at the javadocs.)
Here's the correct code (in Java);
package test;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.zip.GZIPInputStream;
import java.util.zip.GZIPOutputStream;
public class GZipTest {
public static void main(String[] args) throws
FileNotFoundException, IOException {
String name = "/tmp/test";
GZIPOutputStream gz = new GZIPOutputStream(new FileOutputStream(name));
gz.write(10);
gz.close(); // Remove this to reproduce the reported bug
System.out.println(new GZIPInputStream(new FileInputStream(name)).read());
}
}
(I've not implemented resource management or exception handling / reporting properly as they are not relevant to the purpose of this code. Don't treat this as an example of "good code".)
One way is to create a Spliterator
from the Iterator
and use that as a basis for your stream:
Iterator<String> sourceIterator = Arrays.asList("A", "B", "C").iterator();
Stream<String> targetStream = StreamSupport.stream(
Spliterators.spliteratorUnknownSize(sourceIterator, Spliterator.ORDERED),
false);
An alternative which is maybe more readable is to use an Iterable
- and creating an Iterable
from an Iterator
is very easy with lambdas because Iterable
is a functional interface:
Iterator<String> sourceIterator = Arrays.asList("A", "B", "C").iterator();
Iterable<String> iterable = () -> sourceIterator;
Stream<String> targetStream = StreamSupport.stream(iterable.spliterator(), false);
You can have a look on these built-in classes :
How NOT to do it:
.sorted(Comparator.reverseOrder())
or .sorted(Collections.reverseOrder())
, because it will just sort elements in the descending order.[1, 4, 2, 5, 3]
[5, 4, 3, 2, 1]
["A", "D", "B", "E", "C"]
[E, D, C, B, A]
.sorted((a, b) -> -1)
(explanation at the end)The easiest way to do it properly:
List<Integer> list = Arrays.asList(1, 4, 2, 5, 3);
Collections.reverse(list);
System.out.println(list);
Output:
[3, 5, 2, 4, 1]
The same for String
:
List<String> stringList = Arrays.asList("A", "D", "B", "E", "C");
Collections.reverse(stringList);
System.out.println(stringList);
Output:
[C, E, B, D, A]
Don't use .sorted((a, b) -> -1)
!
It breaks comparator contract and might work only for some cases ie. only on single thread but not in parallel.
yankee explanation:
(a, b) -> -1
breaks the contract forComparator
. Whether this works depends on the implementation of the sort algorithm. The next release of the JVM might break this. Actually I can already break this reproduciblly on my machine usingIntStream.range(0, 10000).parallel().boxed().sorted((a, b) -> -1).forEachOrdered(System.out::println);
//Don't use this!!!
List<Integer> list = Arrays.asList(1, 4, 2, 5, 3);
List<Integer> reversedList = list.stream()
.sorted((a, b) -> -1)
.collect(Collectors.toList());
System.out.println(reversedList);
Output in positive case:
[3, 5, 2, 4, 1]
Possible output in parallel stream or with other JVM implementation:
[4, 1, 2, 3, 5]
The same for String
:
//Don't use this!!!
List<String> stringList = Arrays.asList("A", "D", "B", "E", "C");
List<String> reversedStringList = stringList.stream()
.sorted((a, b) -> -1)
.collect(Collectors.toList());
System.out.println(reversedStringList);
Output in positive case:
[C, E, B, D, A]
Possible output in parallel stream or with other JVM implementation:
[A, E, B, D, C]
You can build your HttpContent
using the combination of JObject
to avoid and JProperty
and then call ToString()
on it when building the StringContent
:
/*{
"agent": {
"name": "Agent Name",
"version": 1
},
"username": "Username",
"password": "User Password",
"token": "xxxxxx"
}*/
JObject payLoad = new JObject(
new JProperty("agent",
new JObject(
new JProperty("name", "Agent Name"),
new JProperty("version", 1)
),
new JProperty("username", "Username"),
new JProperty("password", "User Password"),
new JProperty("token", "xxxxxx")
)
);
using (HttpClient client = new HttpClient())
{
var httpContent = new StringContent(payLoad.ToString(), Encoding.UTF8, "application/json");
using (HttpResponseMessage response = await client.PostAsync(requestUri, httpContent))
{
response.EnsureSuccessStatusCode();
string responseBody = await response.Content.ReadAsStringAsync();
return JObject.Parse(responseBody);
}
}
I got the same issue but Sometimes, the most dificult issue get simple answer.
I recheck the manifest permisions and there WAS_NOT write permision shame of me!!!
You can't expect ObjectInputStream
to automagically convert text into objects. The hexadecimal 54657374
is "Test"
as text. You must be sending it directly as bytes.
Your OneThread Class also should implement Serializable. All the sub classes and inner sub classes must implements Serializable.
this is worked for me...
Don't call write.close()
in writeToFile()
.
Don't know about what the error you are facing exactly. But log4j:WARN No appenders could be found for logger error
, is due to the log4j jar file that you have included in your project.
Initializing log4j is needed but actually Log4j is not necessary for your project. So Right click on your Project → Properties → Java Build Path → Libraries.. Search for log4j jar file and remove it.
Hope it will work fine now.
I've found that this is a sign that the server where you're deploying code has an old .NET framework installed that doesn't support TLS 1.1 or TLS 1.2. Steps to fix:
You can get the latest .NET Developer Pack and Runtime from this URL: http://getdotnet.azurewebsites.net/target-dotnet-platforms.html
If you are making jquery ajax request, dont forget to add
contentType:'application/json'
Comparator
is a functional interface, and Integer::max
complies with that interface (after autoboxing/unboxing is taken into consideration). It takes two int
values and returns an int
- just as you'd expect a Comparator<Integer>
to (again, squinting to ignore the Integer/int difference).
However, I wouldn't expect it to do the right thing, given that Integer.max
doesn't comply with the semantics of Comparator.compare
. And indeed it doesn't really work in general. For example, make one small change:
for (int i = 1; i <= 20; i++)
list.add(-i);
... and now the max
value is -20 and the min
value is -1.
Instead, both calls should use Integer::compare
:
System.out.println(list.stream().max(Integer::compare).get());
System.out.println(list.stream().min(Integer::compare).get());
You can use this api https://code.google.com/p/google-gson/
It's simple and very useful,
Here's how to use the https://code.google.com/p/google-gson/ Api to resolve your problem
public class Test {
public static void main(String... strings) throws FileNotFoundException {
Reader reader = new FileReader(new File("<fullPath>/json.js"));
JsonElement elem = new JsonParser().parse(reader);
Gson gson = new GsonBuilder().create();
TestObject o = gson.fromJson(elem, TestObject.class);
System.out.println(o);
}
}
class TestObject{
public String fName;
public String lName;
public String toString() {
return fName +" "+lName;
}
}
json.js file content :
{"fName":"Mohamed",
"lName":"Ali"
}
You are trying to read xls
with explicit implementation poi classes for xlsx
.
G:\Selenium Jar Files\TestData\Data.xls
Either use HSSFWorkbook
and HSSFSheet
classes or make your implementation more generic by using shared interfaces, like;
Change:
XSSFWorkbook workbook = new XSSFWorkbook(file);
To:
org.apache.poi.ss.usermodel.Workbook workbook = WorkbookFactory.create(file);
And Change:
XSSFSheet sheet = workbook.getSheetAt(0);
To:
org.apache.poi.ss.usermodel.Sheet sheet = workbook.getSheetAt(0);
npm ERR! node -v v0.8.0
npm ERR! npm -v 1.1.32
Update your node.js installation.The following commands should do it (from here):
sudo npm cache clean -f
sudo npm install -g n
sudo n stable
Edit: okay, if you really have a good reason to run an ancient version of the software, npm set ca null
will fix the issue. It happened, because built-in npm certificate has expired over the years.
Have you tried using the WebClient class?
you should be able to use
string result = "";
using (var client = new WebClient())
{
client.Headers[HttpRequestHeader.ContentType] = "application/json";
result = client.UploadString(url, "POST", json);
}
Console.WriteLine(result);

My Hosting server block requesting URL And code site getting the same error
Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host
After a lot of time spent and apply the following step to resolve this issue
Added line before the call web URL
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls;
still issue not resolve then I upgrade .net version to 4.7.2 but I think it's optional
Last change I have checked my hosting server security level which causes to TLS handshaking for this used "https://www.ssllabs.com/ssltest/index.html" site
and also check to request URL security level then I find the difference is requested URL have to enable a weak level Cipher Suites you can see in the below image
Now here are my hosting server supporting Cipher Suites
here is called if you have control over requesting URL host server then you can sync this both server Cipher Suites. but in my case, it's not possible so I have applied the following script in Windows PowerShell on my hosting server for enabling required weak level Cipher Suites.
Enable-TlsCipherSuite -Name "TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384"
Enable-TlsCipherSuite -Name "TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256"
Enable-TlsCipherSuite -Name "TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA"
Enable-TlsCipherSuite -Name "TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA"
Enable-TlsCipherSuite -Name "TLS_DHE_RSA_WITH_AES_256_CBC_SHA"
Enable-TlsCipherSuite -Name "TLS_DHE_RSA_WITH_AES_128_CBC_SHA"
Enable-TlsCipherSuite -Name "TLS_RSA_WITH_AES_256_GCM_SHA384"
Enable-TlsCipherSuite -Name "TLS_RSA_WITH_AES_128_GCM_SHA256"
Enable-TlsCipherSuite -Name "TLS_RSA_WITH_AES_256_CBC_SHA256"
Enable-TlsCipherSuite -Name "TLS_RSA_WITH_AES_128_CBC_SHA256"
Enable-TlsCipherSuite -Name "TLS_RSA_WITH_AES_256_CBC_SHA"
Enable-TlsCipherSuite -Name "TLS_RSA_WITH_AES_256_CBC_SHA"
after applying the above script my hosting server Cipher Suites level look like
Then my issue resolved.
Note: server security level downgrade is not a recommended option.
Following solution worked for me. When connecting to the db, specify that data should be truncated if they are too long (jdbcCompliantTruncation). My link looks like this:
jdbc:mysql://SERVER:PORT_NO/SCHEMA?sessionVariables=sql_mode='NO_ENGINE_SUBSTITUTION'&jdbcCompliantTruncation=false
If you increase the size of the strings, you may face the same problem in future if the string you are attempting to store into the DB is longer than the new size.
EDIT: STRICT_TRANS_TABLES has to be removed from sql_mode as well.
You can use this code for connect and request using http and json
try {
URL url = new URL("https://www.googleapis.com/youtube/v3/playlistItems?part=snippet"
+ "&key="+key
+ "&access_token=" + access_token);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setDoOutput(true);
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", "application/json");
String input = "{ \"snippet\": {\"playlistId\": \"WL\",\"resourceId\": {\"videoId\": \""+videoId+"\",\"kind\": \"youtube#video\"},\"position\": 0}}";
OutputStream os = conn.getOutputStream();
os.write(input.getBytes());
os.flush();
if (conn.getResponseCode() != HttpURLConnection.HTTP_CREATED) {
throw new RuntimeException("Failed : HTTP error code : "
+ conn.getResponseCode());
}
BufferedReader br = new BufferedReader(new InputStreamReader(
(conn.getInputStream())));
String output;
System.out.println("Output from Server .... \n");
while ((output = br.readLine()) != null) {
System.out.println(output);
}
conn.disconnect();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
This is what solve my problem.
If you are trying to use debugger make sure you breakpoint is not on URL or URLConnection just put your breakpoint on BufferReader or inside while loop.
If nothing works try using apache library http://hc.apache.org/index.html.
no SSL, no JDK update needed, no need to set properties even, just simple trick :)
NullPointerException
s are among the easier exceptions to diagnose, frequently. Whenever you get an exception in Java and you see the stack trace ( that's what your second quote-block is called, by the way ), you read from top to bottom. Often, you will see exceptions that start in Java library code or in native implementations methods, for diagnosis you can just skip past those until you see a code file that you wrote.
Then you like at the line indicated and look at each of the objects ( instantiated classes ) on that line -- one of them was not created and you tried to use it. You can start by looking up in your code to see if you called the constructor on that object. If you didn't, then that's your problem, you need to instantiate that object by calling new Classname( arguments ). Another frequent cause of NullPointerException
s is accidentally declaring an object with local scope when there is an instance variable with the same name.
In your case, the exception occurred in your constructor for Workshop on line 75. <init>
means the constructor for a class. If you look on that line in your code, you'll see the line
denimjeansButton.addItemListener(this);
There are fairly clearly two objects on this line: denimjeansButton
and this
. this
is synonymous with the class instance you are currently in and you're in the constructor, so it can't be this
. denimjeansButton
is your culprit. You never instantiated that object. Either remove the reference to the instance variable denimjeansButton
or instantiate it.
I was facing the same issue and get it resolved using the below simple steps:
1) Download the InstallCert.java from google
2) Compile it using javac InstallCert.java
3) Run InstallCert.java using java InstallCert.java, with the hostname and https port, and press “1” when asking for input. It will add the “localhost” as a trusted keystore, and generate a file named “jssecacerts“ as below:
java InstallCert localhost:443
4) copy the jssecacerts into $JAVA_HOME/jre/lib/security folder
Main source to resolve the issue here is:
https://ankurjain26.blogspot.in/2017/11/javaxnetsslsslhandshakeexception.html
You state in the comments that the returned JSON is this:
{
"dstOffset" : 3600,
"rawOffset" : 36000,
"status" : "OK",
"timeZoneId" : "Australia/Hobart",
"timeZoneName" : "Australian Eastern Daylight Time"
}
You're telling Gson that you have an array of Post
objects:
List<Post> postsList = Arrays.asList(gson.fromJson(reader,
Post[].class));
You don't. The JSON represents exactly one Post
object, and Gson is telling you that.
Change your code to be:
Post post = gson.fromJson(reader, Post.class);
This will work:
The problem may happen when you're trying to read a list with a single element as a JsonArray rather than a JsonNode or vice versa.
Since you can't know for sure if the returned list contains a single element (so the json looks like this {...}) or multiple elements (and the json looks like this [{...},{...}]) - you'll have to check in runtime the type of the element.
It should look like this:
(Note: in this code sample I'm using com.fasterxml.jackson)
String jsonStr = response.readEntity(String.class);
ObjectMapper mapper = new ObjectMapper();
JsonNode rootNode = mapper.readTree(jsonStr);
// Start by checking if this is a list -> the order is important here:
if (rootNode instanceof ArrayNode) {
// Read the json as a list:
myObjClass[] objects = mapper.readValue(rootNode.toString(), myObjClass[].class);
...
} else if (rootNode instanceof JsonNode) {
// Read the json as a single object:
myObjClass object = mapper.readValue(rootNode.toString(), myObjClass.class);
...
} else {
...
}

if you don't know were is file id then check this article Article LINK
If the advice to add the closing braces work, I suggest adding indentation to your code so every closing brace is on a spaced separately, i.e.:
public class LuisRp3 {
public static void main(String[] args) throws FileNotFoundException {
// stuff
}
}
This just helps with readability.
If, on the other hand, you just forgot to copy the closing braces in your code, or the above suggestion doesn't work: open up the configuration and see if you can manually set the main class. I'm afraid I haven't used NetBeans much, so I can't help you with where that option is. My best guess is under "Run Configuration", or something like that.
Edit: See peeskillet's answer if adding closing braces doesn't work.
First of all you missed ScriptService attribute to add in webservice.
[ScriptService]
After then try following method to call webservice via JSON.
var webAddr = "http://Domain/VBRService.asmx/callJson"; var httpWebRequest = (HttpWebRequest)WebRequest.Create(webAddr); httpWebRequest.ContentType = "application/json; charset=utf-8"; httpWebRequest.Method = "POST"; using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream())) { string json = "{\"x\":\"true\"}"; streamWriter.Write(json); streamWriter.Flush(); } var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse(); using (var streamReader = new StreamReader(httpResponse.GetResponseStream())) { var result = streamReader.ReadToEnd(); return result; }
You need to install all necessary packages with Android SDK Manager:
Android SDK Tools
Android SDK Platform-tools
Android SDK Build-tools
SDK Platform
ARM\Intel System Image
Android Support Repository
Android Support Library
I use something like this to load properties file.
final ResourceBundle bundle = ResourceBundle
.getBundle("properties/errormessages");
for (final Enumeration<String> keys = bundle.getKeys(); keys
.hasMoreElements();) {
final String key = keys.nextElement();
final String value = bundle.getString(key);
prop.put(key, value);
}
Try this method to get path of original
image captured by camera.
public String getOriginalImagePath() {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = getActivity().managedQuery(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
projection, null, null, null);
int column_index_data = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToLast();
return cursor.getString(column_index_data);
}
This method will return path of the last image captured by camera. So this path would be of original image not of thumbnail bitmap.
The name
is present inside the data
. You need to parse a JSON hierarchically to be able to fetch the data properly.
JSONObject jObject = new JSONObject(output); // json
JSONObject data = jObject.getJSONObject("data"); // get data object
String projectname = data.getString("name"); // get the name from data.
Note: This example uses the org.json.JSONObject
class and not org.json.simple.JSONObject
.
As "Matthew" mentioned in the comments that he is using org.json.simple.JSONObject
, I'm adding my comment details in the answer.
Try to use the
org.json.JSONObject
instead. But then if you can't change your JSON library, you can refer to this example which uses the same library as yours and check the how to read a json part from it.
Sample from the link provided:
JSONObject jsonObject = (JSONObject) obj;
String name = (String) jsonObject.get("name");
I've been playing around a little bit and came up with a simplified, more generic solution:
private static string sendHttpRequest(string url, NameValueCollection values, NameValueCollection files = null)
{
string boundary = "----------------------------" + DateTime.Now.Ticks.ToString("x");
// The first boundary
byte[] boundaryBytes = System.Text.Encoding.UTF8.GetBytes("\r\n--" + boundary + "\r\n");
// The last boundary
byte[] trailer = System.Text.Encoding.UTF8.GetBytes("\r\n--" + boundary + "--\r\n");
// The first time it itereates, we need to make sure it doesn't put too many new paragraphs down or it completely messes up poor webbrick
byte[] boundaryBytesF = System.Text.Encoding.ASCII.GetBytes("--" + boundary + "\r\n");
// Create the request and set parameters
HttpWebRequest request = (HttpWebRequest) WebRequest.Create(url);
request.ContentType = "multipart/form-data; boundary=" + boundary;
request.Method = "POST";
request.KeepAlive = true;
request.Credentials = System.Net.CredentialCache.DefaultCredentials;
// Get request stream
Stream requestStream = request.GetRequestStream();
foreach (string key in values.Keys)
{
// Write item to stream

You can use it like this:
string fileLocation = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) + Path.DirectorySeparatorChar + "somefile.jpg";
NameValueCollection values = new NameValueCollection();
NameValueCollection files = new NameValueCollection();
values.Add("firstName", "Alan");
files.Add("profilePicture", fileLocation);
sendHttpRequest("http://example.com/handler.php", values, files);
And in the PHP script you could handle data like this:
echo $_POST['firstName'];
$name = $_POST['firstName'];
$image = $_FILES['profilePicture'];
$ds = DIRECTORY_SEPARATOR;
move_uploaded_file($image['tmp_name'], realpath(dirname(__FILE__)) . $ds . "uploads" . $ds . $image['name']);

With Kotlin have this extension function to read the file return as string.
fun AssetManager.readAssetsFile(fileName : String): String = open(fileName).bufferedReader().use{it.readText()}
Parse the output string using any JSON parser.
Make sure when you create a txt file you don't type in the name "name.txt", just type in "name". If you type "name.txt" Eclipse will see it as "name.txt.txt". This solved it for me. Also save the file in the src folder, not the folder were the .java resides, one folder up.
The problem you have is related to TCP streaming nature.
The fact that you sent 100 Bytes (for example) from the server doesn't mean you will read 100 Bytes in the client the first time you read. Maybe the bytes sent from the server arrive in several TCP segments to the client.
You need to implement a loop in which you read until the whole message was received.
Let me provide an example with DataInputStream
instead of BufferedinputStream
. Something very simple to give you just an example.
Let's suppose you know beforehand the server is to send 100 Bytes of data.
In client you need to write:
byte[] messageByte = new byte[1000];
boolean end = false;
String dataString = "";
try
{
DataInputStream in = new DataInputStream(clientSocket.getInputStream());
while(!end)
{
int bytesRead = in.read(messageByte);
dataString += new String(messageByte, 0, bytesRead);
if (dataString.length == 100)
{
end = true;
}
}
System.out.println("MESSAGE: " + dataString);
}
catch (Exception e)
{
e.printStackTrace();
}
Now, typically the data size sent by one node (the server here) is not known beforehand. Then you need to define your own small protocol for the communication between server and client (or any two nodes) communicating with TCP.
The most common and simple is to define TLV: Type, Length, Value. So you define that every message sent form server to client comes with:
So you know you have to receive a minimum of 2 Bytes and with the second Byte you know how many following Bytes you need to read.
This is just a suggestion of a possible protocol. You could also get rid of "Type".
So it would be something like:
byte[] messageByte = new byte[1000];
boolean end = false;
String dataString = "";
try
{
DataInputStream in = new DataInputStream(clientSocket.getInputStream());
int bytesRead = 0;
messageByte[0] = in.readByte();
messageByte[1] = in.readByte();
int bytesToRead = messageByte[1];
while(!end)
{
bytesRead = in.read(messageByte);
dataString += new String(messageByte, 0, bytesRead);
if (dataString.length == bytesToRead )
{
end = true;
}
}
System.out.println("MESSAGE: " + dataString);
}
catch (Exception e)
{
e.printStackTrace();
}
The following code compiles and looks better. It assumes the first two bytes providing the length arrive in binary format, in network endianship (big endian). No focus on different encoding types for the rest of the message.
import java.nio.ByteBuffer;
import java.io.DataInputStream;
import java.net.ServerSocket;
import java.net.Socket;
class Test
{
public static void main(String[] args)
{
byte[] messageByte = new byte[1000];
boolean end = false;
String dataString = "";
try
{
Socket clientSocket;
ServerSocket server;
server = new ServerSocket(30501, 100);
clientSocket = server.accept();
DataInputStream in = new DataInputStream(clientSocket.getInputStream());
int bytesRead = 0;
messageByte[0] = in.readByte();
messageByte[1] = in.readByte();
ByteBuffer byteBuffer = ByteBuffer.wrap(messageByte, 0, 2);
int bytesToRead = byteBuffer.getShort();
System.out.println("About to read " + bytesToRead + " octets");
//The following code shows in detail how to read from a TCP socket
while(!end)
{
bytesRead = in.read(messageByte);
dataString += new String(messageByte, 0, bytesRead);
if (dataString.length() == bytesToRead )
{
end = true;
}
}
//All the code in the loop can be replaced by these two lines
//in.readFully(messageByte, 0, bytesToRead);
//dataString = new String(messageByte, 0, bytesToRead);
System.out.println("MESSAGE: " + dataString);
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
I got this exception too. MY error code is below
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod(requestMethod);
connection.setRequestProperty("Content-type", "JSON");
I found "Content-type" should not be "JSON",is wrong! I solved this exception by update this line to below
connection.setRequestProperty("Content-type", "application/json");
you can check up your "Content-type"
You need to include xmlbeans-xxx.jar and if you have downloaded the POI binary zip, you will get the xmlbeans-xxx.jar in ooxml-lib folder (eg: \poi-3.11\ooxml-lib)
This jar is used for XML binding which is applicable for .xlsx files.
I sorted this problem as verifying the json from JSONLint.com and then, correcting it. And this is code for the same.
String jsonStr = "[{\r\n" + "\"name\":\"New York\",\r\n" + "\"number\": \"732921\",\r\n"+ "\"center\": {\r\n" + "\"latitude\": 38.895111,\r\n" + " \"longitude\": -77.036667\r\n" + "}\r\n" + "},\r\n" + " {\r\n"+ "\"name\": \"San Francisco\",\r\n" +\"number\":\"298732\",\r\n"+ "\"center\": {\r\n" + " \"latitude\": 37.783333,\r\n"+ "\"longitude\": -122.416667\r\n" + "}\r\n" + "}\r\n" + "]";
ObjectMapper mapper = new ObjectMapper();
MyPojo[] jsonObj = mapper.readValue(jsonStr, MyPojo[].class);
for (MyPojo itr : jsonObj) {
System.out.println("Val of name is: " + itr.getName());
System.out.println("Val of number is: " + itr.getNumber());
System.out.println("Val of latitude is: " +
itr.getCenter().getLatitude());
System.out.println("Val of longitude is: " +
itr.getCenter().getLongitude() + "\n");
}
Note: MyPojo[].class
is the class having getter and setter of json properties.

VB6/VBA uses deterministic approach to destoying objects. Each object stores number of references to itself. When the number reaches zero, the object is destroyed.
Object variables are guaranteed to be cleaned (set to Nothing
) when they go out of scope, this decrements the reference counters in their respective objects. No manual action required.
There are only two cases when you want an explicit cleanup:
When you want an object to be destroyed before its variable goes out of scope (e.g., your procedure is going to take long time to execute, and the object holds a resource, so you want to destroy the object as soon as possible to release the resource).
When you have a circular reference between two or more objects.
If objectA
stores a references to objectB
, and objectB
stores a reference to objectA
, the two objects will never get destroyed unless you brake the chain by explicitly setting objectA.ReferenceToB = Nothing
or objectB.ReferenceToA = Nothing
.
The code snippet you show is wrong. No manual cleanup is required. It is even harmful to do a manual cleanup, as it gives you a false sense of more correct code.
If you have a variable at a class level, it will be cleaned/destroyed when the class instance is destructed. You can destroy it earlier if you want (see item 1.
).
If you have a variable at a module level, it will be cleaned/destroyed when your program exits (or, in case of VBA, when the VBA project is reset). You can destroy it earlier if you want (see item 1.
).
Access level of a variable (public vs. private) does not affect its life time.

Consider Moshi's JsonWriter class (source). It has a wonderful API and it reduces copying to a minimum, everything is nicely streamed to the OutputStream.
OutputStream os = ...;
JsonWriter json = new JsonWriter(Okio.sink(os));
json
.beginObject()
.name("id").value(userID)
.name("type").value(methodn)
...
.endObject();
There's no mystery here, the linker is telling you that you haven't defined the missing symbols, and you haven't.
Similarity::Similarity()
or Similarity::~Similarity()
are just missing and you have defined the others incorrectly,
void Similarity::readData(Scanner& inStream){
}
not
void readData(Scanner& inStream){
}
etc. etc.
The second one is a function called readData, only the first is the readData method of the Similarity class.
To be clear about this, in Similarity.h
void readData(Scanner& inStream);
but in Similarity.cpp
void Similarity::readData(Scanner& inStream){
}
try below code it will solve your problem.
Configuration configuration = new Configuration().configure("/logic/hibernate.cfg.xml");

b[i] = (byte)(Integer.parseInt(tmp, 16) & 0xff);
}

Postman is the best application to test your APIs !
You can import or export your routes and let him remember all your body requests ! :)
EDIT : This comment is 5 yea's old and deprecated :D
Here's the new Postman App : https://www.postman.com/
There are two Things you can do
use
int noOfColumns = sh.getRow(0).getPhysicalNumberOfCells();
or
int noOfColumns = sh.getRow(0).getLastCellNum();
There is a fine difference between them
You can use while(in.available() != 0)
instead of while(true)
.
grantUriPermission (from Android document)
Normally you should use Intent#FLAG_GRANT_READ_URI_PERMISSION or Intent#FLAG_GRANT_WRITE_URI_PERMISSION with the Intent being used to start an activity instead of this function directly. If you use this function directly, you should be sure to call revokeUriPermission(Uri, int) when the target should no longer be allowed to access it.
So I test and I see that.
If we use grantUriPermission
before we start a new activity, we DON'T need
FLAG_GRANT_READ_URI_PERMISSION
or FLAG_GRANT_WRITE_URI_PERMISSION
in Intent
to overcome SecurityException
If we don't use grantUriPermission
. We need to use FLAG_GRANT_READ_URI_PERMISSION
or FLAG_GRANT_WRITE_URI_PERMISSION
to overcome SecurityException
but
Uri
by setData
or setDataAndType
else SecurityException
still throw. (one interesting I see: setData
and setType
can not work well together so if you need both Uri
and type
you need setDataAndType
. You can check inside Intent
code, currently when you setType
, it will also set uri= null and when you setUri it will also set type=null)Try this code to download an image from a URL on Android:
DownloadManager downloadManager = (DownloadManager)getSystemService(Context.DOWNLOAD_SERVICE);
Uri uri = Uri.parse(imageName);
DownloadManager.Request request = new DownloadManager.Request(uri);
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
Long reference = downloadManager.enqueue(request);
This will not be applicable if you set image as background in ImageView, need to set at src(android:src).
Thanks.
This is not the exact answer for your question, but this may help you
public class JsonParser {
private static DefaultHttpClient httpClient = ConnectionManager.getClient();
public static List<Club> getNearestClubs(double lat, double lon) {
// YOUR URL GOES HERE
String getUrl = Constants.BASE_URL + String.format("getClosestClubs?lat=%f&lon=%f", lat, lon);
List<Club> ret = new ArrayList<Club>();
HttpResponse response = null;
HttpGet getMethod = new HttpGet(getUrl);
try {
response = httpClient.execute(getMethod);
// CONVERT RESPONSE TO STRING
String result = EntityUtils.toString(response.getEntity());
// CONVERT RESPONSE STRING TO JSON ARRAY
JSONArray ja = new JSONArray(result);
// ITERATE THROUGH AND RETRIEVE CLUB FIELDS
int n = ja.length();
for (int i = 0; i < n; i++) {
// GET INDIVIDUAL JSON OBJECT FROM JSON ARRAY
JSONObject jo = ja.getJSONObject(i);
// RETRIEVE EACH JSON OBJECT'S FIELDS
long id = jo.getLong("id");
String name = jo.getString("name");
String address = jo.getString("address");
String country = jo.getString("country");
String zip = jo.getString("zip");
double clat = jo.getDouble("lat");
double clon = jo.getDouble("lon");
String url = jo.getString("url");
String number = jo.getString("number");
// CONVERT DATA FIELDS TO CLUB OBJECT
Club c = new Club(id, name, address, country, zip, clat, clon, url, number);
ret.add(c);
}
} catch (Exception e) {
e.printStackTrace();
}
// RETURN LIST OF CLUBS
return ret;
}
}
Again, it’s relatively straight forward, but the methods I’ll make special note of are:
JSONArray ja = new JSONArray(result);
JSONObject jo = ja.getJSONObject(i);
long id = jo.getLong("id");
String name = jo.getString("name");
double clat = jo.getDouble("lat");
I don't think it's enough merely to get the response. I think you need to read it (get the entity and read it via EntityUtils.consume()).
e.g. (from the doc)
System.out.println("<< Response: " + response.getStatusLine());
System.out.println(EntityUtils.toString(response.getEntity()));
With text files, maybe the EOF is -1 when using BufferReader.read(), char by char. I made a test with BufferReader.readLine()!=null and it worked properly.
You can do it with the HTMLWorker
class (deprecated) like this:
import com.itextpdf.text.html.simpleparser.HTMLWorker;
//...
try {
String k = "<html><body> This is my Project </body></html>";
OutputStream file = new FileOutputStream(new File("C:\\Test.pdf"));
Document document = new Document();
PdfWriter.getInstance(document, file);
document.open();
HTMLWorker htmlWorker = new HTMLWorker(document);
htmlWorker.parse(new StringReader(k));
document.close();
file.close();
} catch (Exception e) {
e.printStackTrace();
}
or using the XMLWorker
, (download from this jar) using this code:
import com.itextpdf.tool.xml.XMLWorkerHelper;
//...
try {
String k = "<html><body> This is my Project </body></html>";
OutputStream file = new FileOutputStream(new File("C:\\Test.pdf"));
Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document, file);
document.open();
InputStream is = new ByteArrayInputStream(k.getBytes());
XMLWorkerHelper.getInstance().parseXHtml(writer, document, is);
document.close();
file.close();
} catch (Exception e) {
e.printStackTrace();
}
AlliterativeAlice's example helped me tremendously. In my case, though, the server I was talking to didn't like having single quotes around utf-8
in the content type. It failed with a generic "Server Error"
and it took hours to figure out what it didn't like:
request.ContentType = "text/xml; encoding=utf-8";
You can use a FileOutputStream for this.
FileOutputStream fos = null;
try {
fos = new FileOutputStream(new File("myFile"));
ByteArrayOutputStream baos = new ByteArrayOutputStream();
// Put data in your baos
baos.writeTo(fos);
} catch(IOException ioe) {
// Handle exception here
ioe.printStackTrace();
} finally {
fos.close();
}
I've created a couple of map tutorials that will cover what you need
Animating the map describes howto create polylines based on a set of LatLngs. Using Google APIs on your map : Directions and Places describes howto use the Directions API and animate a marker along the path.
Take a look at these 2 tutorials and the Github project containing the sample app.
It contains some tips to make your code cleaner and more efficient:
Try to import
java.util.List;
instead of
java.awt.List;
I also had this problem. it was weird that it worked on my lollipop emulator, but not on my actual kitkat device.
Android Studio will now force you to write the permission upper case, and that's the problem.
Add
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
Above the application tab and it will work.
Why not serialize the whole list at once?
FileOutputStream fout = new FileOutputStream("G:\\address.ser");
ObjectOutputStream oos = new ObjectOutputStream(fout);
oos.writeObject(MyClassList);
Assuming, of course, that MyClassList is an ArrayList
or LinkedList
, or another Serializable
collection.
In the case of reading it back, in your code you ready only one item, there is no loop to gather all the item written.
Solved by adding the following dependency into pom.xml file :
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<scope>test</scope>
</dependency>
Just in case you guys need it, Here a couple of links that can help you:
Cheers
One thing to take note of is that it is possible for the BeginConnect call to fail before the timeout expires. This may happen if you are attempting a local connection. Here's a modified version of Jon's code...
var client = new TcpClient();
var result = client.BeginConnect("remotehost", Port, null, null);
result.AsyncWaitHandle.WaitOne(TimeSpan.FromSeconds(1));
if (!client.Connected)
{
throw new Exception("Failed to connect.");
}
// we have connected
client.EndConnect(result);
I had the same problem while trying to read the data from the request body. In my case which occurs randomly only to the mobile-based client devices. So I have increased the connectionUploadTimeout
to 1min as suggested by this link
I think it's because your DB_Path
finishes without a "/". When you concatenate the path with the database, the variable myPath
has the following string: "/data/data/com.example.quotes/databasesQuotesdb"
.
I propose these changes:
private static String DB_PATH = "/data/data/com.example.quotes/databases/";
private static String DB_NAME = "Quotesdb.db";
And another thing, you should open the database in the Main activity, and implement the onPause()
and onResume()
methods with database.close()
and database.open()
respectively. This is my example for the Main Activity (used with Cordova, web design and all the stuff =P):
package home.shell.accessApp;
import android.os.Bundle;
import android.util.Log;
import org.apache.cordova.*;
public class AccessApp extends CordovaActivity {
private SellitDAO db; //This is the class name for my SQLiteOpenHelper
@Override
public void onCreate(Bundle savedInstanceState) {
db = new SellitDAO(this);
db.open();
super.onCreate(savedInstanceState);
super.init();
// Set by <content src="index.html" /> in config.xml
super.loadUrl(Config.getStartUrl());
//super.loadUrl("file:///android_asset/www/index.html")
}
@Override
public void onPause() {
super.onPause();
db.close();
}
@Override
public void onResume() {
super.onResume();
db.open();
}
}
Good Luck!!!
You could also recursively walk through a folder and lists all it's contents using pathlib.Path()
from pathlib import Path
def check_out_path(target_path, level=0):
""""
This function recursively prints all contents of a pathlib.Path object
"""
def print_indented(folder, level):
print('\t' * level + folder)
print_indented(target_path.name, level)
for file in target_path.iterdir():
if file.is_dir():
check_out_path(file, level+1)
else:
print_indented(file.name, level+1)
my_path = Path(r'C:\example folder')
check_out_path(my_path)
Output:
example folder
folder
textfile3.txt
textfile1.txt
textfile2.txt
import java.io.*;
public class FileRead {
public static void main(String[] args) throws IOException {
File f=new File("C:\\Documents and Settings\\abc\\Desktop\\abc.pdf");
OutputStream oos = new FileOutputStream("test.pdf");
byte[] buf = new byte[8192];
InputStream is = new FileInputStream(f);
int c = 0;
while ((c = is.read(buf, 0, buf.length)) > 0) {
oos.write(buf, 0, c);
oos.flush();
}
oos.close();
System.out.println("stop");
is.close();
}
}
The easiest way so far. Hope this helps.
Because font doesn't have color, you need a panel to make a backgound color and give the foreground color for both JLabel (if you use JLabel) and JPanel to make font color, like example below :
JLabel lblusr = new JLabel("User name : ");
lblusr.setForeground(Color.YELLOW);
JPanel usrPanel = new JPanel();
Color maroon = new Color (128, 0, 0);
usrPanel.setBackground(maroon);
usrPanel.setOpaque(true);
usrPanel.setForeground(Color.YELLOW);
usrPanel.add(lblusr);
The background color of label is maroon with yellow font color.
You were on the right track with response.getOutputStream()
, but you're not using its output anywhere in your code. Essentially what you need to do is to stream the PDF file's bytes directly to the output stream and flush the response. In Spring you can do it like this:
@RequestMapping(value="/getpdf", method=RequestMethod.POST)
public ResponseEntity<byte[]> getPDF(@RequestBody String json) {
// convert JSON to Employee
Employee emp = convertSomehow(json);
// generate the file
PdfUtil.showHelp(emp);
// retrieve contents of "C:/tmp/report.pdf" that were written in showHelp
byte[] contents = (...);
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_PDF);
// Here you have to set the actual filename of your pdf
String filename = "output.pdf";
headers.setContentDispositionFormData(filename, filename);
headers.setCacheControl("must-revalidate, post-check=0, pre-check=0");
ResponseEntity<byte[]> response = new ResponseEntity<>(contents, headers, HttpStatus.OK);
return response;
}
Notes:
showHelp
is not a good ideabyte[]
: example hereshowHelp()
to avoid overwriting the file if two users send a request at the same timeThis is a solution without creating manually a file on disc :
MultipartFile fichier = new MockMultipartFile("fileThatDoesNotExists.txt",
"fileThatDoesNotExists.txt",
"text/plain",
"This is a dummy file content".getBytes(StandardCharsets.UTF_8));
An alternative could be to use the new JSON extension for SQLite. I've only just come across this myself: https://www.sqlite.org/json1.html This would allow you to perform a certain level of querying the stored JSON. If you used VARCHAR or TEXT to store a JSON string you would have no ability to query it. This is a great article showing its usage (in python) http://charlesleifer.com/blog/using-the-sqlite-json1-and-fts5-extensions-with-python/
Lifepaths.class.getClass().getResourceAsStream(...)
loads resources using system class loader, it obviously fails because it does not see your JARs
Lifepaths.class.getResourceAsStream(...)
loads resources using the same class loader that loaded Lifepaths class and it should have access to resources in your JARs
You can use the as operator to perform certain types of conversions between compatible reference types or nullable types.
SkyfilterClient c = client as SkyfilterClient;
if (c != null)
{
//do something with it
}
NetworkClient c = new SkyfilterClient() as NetworkClient; // c is not null
SkyfilterClient c2 = new NetworkClient() as SkyfilterClient; // c2 is null
Use StrictMode Something like this:-
if (android.os.Build.VERSION.SDK_INT > 9) {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}
This is because of
String outStr = obj.toString("UTF-8");
Send the byte[]
which you can get from your ByteArrayOutputStream
and use it as such in your ByteArrayInputStream
to construct your GZIPInputStream
. Following are the changes which need to be done in your code.
byte[] compressed = compress(string); //In the main method
public static byte[] compress(String str) throws Exception {
...
...
return obj.toByteArray();
}
public static String decompress(byte[] bytes) throws Exception {
...
GZIPInputStream gis = new GZIPInputStream(new ByteArrayInputStream(bytes));
...

As of Java 9, the JDK includes jshell
, a Java REPL.
Assuming the JDK 9+ bin
directory is correctly added to your path, you will be able to simply:
jshell File.java
— File.java
being your file of course. main
method: jshell> File.main(null)
./exit
Full documentation for JShell can be found here.
As an exercise, I would suggest doing the following:
public void save(String fileName) throws FileNotFoundException {
PrintWriter pw = new PrintWriter(new FileOutputStream(fileName));
for (Club club : clubs)
pw.println(club.getName());
pw.close();
}
This will write the name of each club on a new line in your file.
Soccer Chess Football Volleyball ...
I'll leave the loading to you. Hint: You wrote one line at a time, you can then read one line at a time.
Every class in Java extends the Object
class. As such you can override its methods. In this case, you should be interested by the toString()
method. In your Club
class, you can override it to print some message about the class in any format you'd like.
public String toString() {
return "Club:" + name;
}
You could then change the above code to:
public void save(String fileName) throws FileNotFoundException {
PrintWriter pw = new PrintWriter(new FileOutputStream(fileName));
for (Club club : clubs)
pw.println(club); // call toString() on club, like club.toString()
pw.close();
}
Bit late for an answer, but here's what I came up with using Gson:
for a jsonarray foo: [{"test": "bar"}, {"test": "bar2"}]
JsonArray foo = getJsonFromWherever();
String[] test = new String[foo.size()]
foo.forEach(x -> {test = ArrayUtils.add(test, x.get("test").getAsString());});
use AsyncTask
and
put your download file code in doinbackground
of it..
android don't allow anymore to do heavy tasks on main thread to avoid ANR(Application not responding) error
Does the code work when not running the Maven-build jar, for example when running from your IDE? If so, make sure the file is actually included in the jar. The resources folder should be included in the pom file, in <build><resources>
.
To use internal storage for the application, you don't need permission, but you may need to use: File directory = getApplication().getCacheDir();
to get the allowed directory for the app.
Or:
getCashDir();
<-- should work
context.getCashDir();
(if in a broadcast receiver)
getDataDir();
<--Api 24
My way of achieving this is by creating ZipInputStream wrapping class that would handle that would provide only the stream of current entry:
The wrapper class:
public class ZippedFileInputStream extends InputStream {
private ZipInputStream is;
public ZippedFileInputStream(ZipInputStream is){
this.is = is;
}
@Override
public int read() throws IOException {
return is.read();
}
@Override
public void close() throws IOException {
is.closeEntry();
}
}
The use of it:
ZipInputStream zipInputStream = new ZipInputStream(new FileInputStream("SomeFile.zip"));
while((entry = zipInputStream.getNextEntry())!= null) {
ZippedFileInputStream archivedFileInputStream = new ZippedFileInputStream(zipInputStream);
//... perform whatever logic you want here with ZippedFileInputStream
// note that this will only close the current entry stream and not the ZipInputStream
archivedFileInputStream.close();
}
zipInputStream.close();
One advantage of this approach: InputStreams are passed as an arguments to methods that process them and those methods have a tendency to immediately close the input stream after they are done with it.
To save file into directory
public static Uri saveImageToInternalStorage(Context mContext, Bitmap bitmap){
String mTimeStamp = new SimpleDateFormat("ddMMyyyy_HHmm").format(new Date());
String mImageName = "snap_"+mTimeStamp+".jpg";
ContextWrapper wrapper = new ContextWrapper(mContext);
File file = wrapper.getDir("Images",MODE_PRIVATE);
file = new File(file, "snap_"+ mImageName+".jpg");
try{
OutputStream stream = null;
stream = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG,100,stream);
stream.flush();
stream.close();
}catch (IOException e)
{
e.printStackTrace();
}
Uri mImageUri = Uri.parse(file.getAbsolutePath());
return mImageUri;
}
required permission
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
I've searched all over the web and after reading lot of docs regarding connection timeout exception, the thing I understood is that, preventing SocketTimeoutException
is beyond our limit. One way to effectively handle it is to define a connection timeout and later handle it by using a try-catch
block. Hope this will help anyone in future who are facing the same issue.
HttpUrlConnection conn = (HttpURLConnection) url.openConnection();
//set the timeout in milliseconds
conn.setConnectTimeout(7000);

You must set proxy server for gradle at some time, you can try to change the proxy server ip address in gradle.properties which is under .gradle document
I had the same problem in my JSF application which was having a comment line containing some special characters in the XMHTL page. When I compared the previous version in my eclipse it had a comment,
//Some ? ? special characters found
Removed those characters and the page loaded fine. Mostly it is related to XML files, so please compare it with the working version.
The linefeed character \n
is not the line separator in certain operating systems (such as windows, where it's "\r\n") - my suggestion is that you use \r\n
instead, then it'll both see the line-break with only \n
and \r\n
, I've never had any problems using it.
Also, you should look into using a StringBuilder
instead of concatenating the String
in the while-loop at BookCatalog.toString()
, it is a lot more effective. For instance:
public String toString() {
BookNode current = front;
StringBuilder sb = new StringBuilder();
while (current!=null){
sb.append(current.getData().toString()+"\r\n ");
current = current.getNext();
}
return sb.toString();
}
As others said, you may run your external program without xterm. However, if you want to run it in a terminal window, e.g. to let the user interact with it, xterm allows you to specify the program to run as parameter.
xterm -e any command
In Java code this becomes:
String[] command = { "xterm", "-e", "my", "command", "with", "parameters" };
Runtime.getRuntime().exec(command);
Or, using ProcessBuilder:
String[] command = { "xterm", "-e", "my", "command", "with", "parameters" };
Process proc = new ProcessBuilder(command).start();
Properties prop = new Properties();
prop.load(...); // FileInputStream
prop.setProperty("key", "value");
prop.store(...); // FileOutputStream
Any API should check the validity of the every parameter of any public method before executing it:
void setPercentage(int pct, AnObject object) {
if( pct < 0 || pct > 100) {
throw new IllegalArgumentException("pct has an invalid value");
}
if (object == null) {
throw new IllegalArgumentException("object is null");
}
}
They represent 99.9% of the times errors in the application because it is asking for impossible operations so in the end they are bugs that should crash the application (so it is a non recoverable error).
In this case and following the approach of fail fast you should let the application finish to avoid corrupting the application state.
Usage:
sftp("file:/C:/home/file.txt", "ssh://user:pass@host/home");
sftp("ssh://user:pass@host/home/file.txt", "file:/C:/home");
One way is to associating unique properties with your file while creation.
properties = "{ \
key='somekey' and \
value='somevalue'
}"
then create a query.
query = "title = " + "\'" + title + "\'" + \
AND + "mimeType = " + "\'" + mimeType + "\'" + \
AND + "trashed = false" + \
AND + "properties has " + properties
All the file properties(title, etc) already known to you can go here + properties.
Quote from the Spring reference doc:
Upon initialization of a DispatcherServlet, Spring MVC looks for a file named [servlet-name]-servlet.xml in the WEB-INF directory of your web application and creates the beans defined there...
Your servlet is called spring-dispatcher
, so it looks for /WEB-INF/spring-dispatcher-servlet.xml
. You need to have this servlet configuration, and define web related beans in there (like controllers, view resolvers, etc). See the linked documentation for clarification on the relation of servlet contexts to the global application context (which is the app-config.xml
in your case).
One more thing, if you don't like the naming convention of the servlet config xml, you can specify your config explicitly:
<servlet>
<servlet-name>spring-dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring/appServlet/servlet-context.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
Ok, I am definitively late to the party but if you are still looking for an optimal solution I would use the following ( for Java 8 )
Charset inputCharset = Charset.forName("ISO-8859-1");
Path pathToFile = ....
try (BufferedReader br = Files.newBufferedReader( pathToFile, inputCharset )) {
...
}
Considering this as a general programming problem, some possible causes are:
The service could be temporarily broken
You could have a problem with a firewall. These could be local or they could be implemented by your ISPs.
Your proxy HTTP settings (if you need one) could be incorrect. This Answer explains how to adjust the Eclipse-internal proxy settings ... if that is where the problem lies.
It is possible that your access may be blocked by over-active antivirus software.
The service could have blacklisted some net range and your hosts IP address is "collateral damage".
Try connecting to that URL with a web browser to try to see if it is just Eclipse that is affected ... or a broader problem.
Considering this in the context of the Eclipse Marketplace service, first address any local proxy / firewall / AV issues, if they apply. If that doesn't help, the best thing that you can do is to be patient.
It has been observed that the Eclipse Marketplace service does sometimes go down. It doesn't happen often, and when it does happen the problem does get fixed relatively quickly. (Hours, not days ...)
I can't find a "service status" page or feed or similar for the Eclipse services. (If you know of one, please add it as a comment below.)
There may be an "outage" notice on the Eclipse front page. Check for that.
Try to connect to the service URL (refer to the exception message!) using a web browser and/or from other locations. If you succeed, the real problem may be a networking issue at your end.
If you feel the need to complain about Eclipse's services, please don't do it here!! (It is off topic.)
Use this code:
internal void SomeFunction() {
Dictionary<string, string> formField = new Dictionary<string, string>();
formField.Add("Name", "Henry");
formField.Add("Age", "21");
string body = GetBodyStringFromDictionary(formField);
// output : Name=Henry&Age=21
}
internal string GetBodyStringFromDictionary(Dictionary<string, string> formField)
{
string body = string.Empty;
foreach (var pair in formField)
{
body += $"{pair.Key}={pair.Value}&";
}
// delete last "&"
body = body.Substring(0, body.Length - 1);
return body;
}
You have to actually call some method to create the directories. Just creating a file
object will not create the corresponding file or directory on the file system.
You can use File#mkdirs()
method to create the directory: -
theFile.mkdirs();
Difference between File#mkdir()
and File#mkdirs()
is that, the later will create any intermediate directory if it does not exist.
You are debugging two or more times. so the application may run more at a time. Then only this issue will occur. You should close all debugging applications using task-manager, Then debug again.
You can do that simple with Files.size(new File(filename).toPath())
.
What does your routeTemplate look like for this case?
You posted this url:
/offers/40D5E19D-0CD5-4FBD-92F8-43FDBB475333/prices/
In order for this to work I would expect a routing like this in your WebApiConfig
:
routeTemplate: {controller}/{offerId}/prices/
Other assumptions are:
- your controller is called OffersController
.
- the JSON object you are passing in the request body is of type OfferPriceParameters
(not any derived type)
- you don't have any other methods on the controller that could interfere with this one (if you do, try commenting them out and see what happens)
And as Filip mentioned it would help your questions if you started accepting some answers as 'accept rate of 0%' might make people think that they are wasting their time

I have seen many production problems caused by code not handling quotes ("), newline characters within quotes, and quotes within the quotes; e.g.: "he said ""this""" should be parsed into: he said "this"
Like it was mentioned earlier, many CSV parsing examples out there just read a line, and then break up the line by the separator character. This is rather incomplete and problematic.
For me and probably those who prefer build verses buy (or use somebody else's code and deal with their dependencies), I got down to classic text parsing programming and that worked for me:
/**
* Parse CSV data into an array of String arrays. It handles double quoted values.
* @param is input stream
* @param separator
* @param trimValues
* @param skipEmptyLines
* @return an array of String arrays
* @throws IOException
*/
public static String[][] parseCsvData(InputStream is, char separator, boolean trimValues, boolean skipEmptyLines)
throws IOException
{
ArrayList<String[]> data = new ArrayList<String[]>();
ArrayList<String> row = new ArrayList<String>();
StringBuffer value = new StringBuffer();
int ch = -1;
int prevCh = -1;
boolean inQuotedValue = false;
boolean quoteAtStart = false;
boolean rowIsEmpty = true;
boolean isEOF = false;
while (true)
{
prevCh = ch;
ch = (isEOF) ? -1 : is.read();
// Handle carriage return line feed
if (prevCh == '\r' && ch == '\n')
{
continue;
}
if (inQuotedValue)
{
if (ch == -1)
{
inQuotedValue = false;
isEOF = true;
}
else
{
value.append((char)ch);
if (ch == '"')
{
inQuotedValue = false;
}
}
}
else if (ch == separator || ch == '\r' || ch == '\n' || ch == -1)
{
// Add the value to the row
String s = value.toString();
if (quoteAtStart && s.endsWith("\""))
{
s = s.substring(1, s.length() - 1);
}
if (trimValues)
{
s = s.trim();
}
rowIsEmpty = (s.length() > 0) ? false : rowIsEmpty;
row.add(s);
value.setLength(0);
if (ch == '\r' || ch == '\n' || ch == -1)
{
// Add the row to the result
if (!skipEmptyLines || !rowIsEmpty)
{
data.add(row.toArray(new String[0]));
}
row.clear();
rowIsEmpty = true;
if (ch == -1)
{
break;
}
}
}
else if (prevCh == '"')
{
inQuotedValue = true;
}
else
{
if (ch == '"')
{
inQuotedValue = true;
quoteAtStart = (value.length() == 0) ? true : false;
}
value.append((char)ch);
}
}
return data.toArray(new String[0][]);
}
Unit Test:
String[][] data = parseCsvData(new ByteArrayInputStream("foo,\"\",,\"bar\",\"\"\"music\"\"\",\"carriage\r\nreturn\",\"new\nline\"\r\nnext,line".getBytes()), ',', true, true);
for (int rowIdx = 0; rowIdx < data.length; rowIdx++)
{
System.out.println(Arrays.asList(data[rowIdx]));
}
generates the output:
[foo, , , bar, "music", carriage
return, new
line]
[next, line]
What type of authentication do you use? Send the credentials using the properties Ben said before and setup a cookie handler. You already allow redirection, check your webserver if any redirection occurs (NTLM auth does for sure). If there is a redirection you need to store the session which is mostly stored in a session cookie.
public static void main(String[] args) {
Properties prop = new Properties();
InputStream input = null;
try {
File f=new File("config.properties");
input = new FileInputStream(f.getPath());
prop.load(input);
System.out.println(prop.getProperty("name"));
} catch (IOException ex) {
ex.printStackTrace();
} finally {
if (input != null) {
try {
input.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
You can also use
Path path1 =FileSystems.getDefault().getPath(System.getProperty("user.home"), "downloads", "somefile.txt");
It's as simple as following:
File logFile = new File(...);
ProcessBuilder pb = new ProcessBuilder()
.command("somecommand", "arg1", "arg2")
processBuilder.redirectErrorStream(true);
processBuilder.redirectOutput(logFile);
by .redirectErrorStream(true) you tell process to merge error and output stream and then by .redirectOutput(file) you redirect merged output to a file.
Update:
I did manage to do this as follows:
public static void main(String[] args) {
// Async part
Runnable r = () -> {
ProcessBuilder pb = new ProcessBuilder().command("...");
// Merge System.err and System.out
pb.redirectErrorStream(true);
// Inherit System.out as redirect output stream
pb.redirectOutput(ProcessBuilder.Redirect.INHERIT);
try {
pb.start();
} catch (IOException e) {
e.printStackTrace();
}
};
new Thread(r, "asyncOut").start();
// here goes your main part
}
Now you're able to see both outputs from main and asyncOut threads in System.out
I had the similar issue, then I found out that wifi was not connected in my smartphone. After I turned on the wifi and connected to the similar network (with my laptop), there was another issue - laptop's firewall was blocking incoming connections. Once I fixed the firewall, I was able to communicate from my android app with the web service running on the laptop.
The best way to access files from resource folder inside a jar is it to use the InputStream via getResourceAsStream
. If you still need a the resource as a file instance you can copy the resource as a stream into a temporary file (the temp file will be deleted when the JVM exits):
public static File getResourceAsFile(String resourcePath) {
try {
InputStream in = ClassLoader.getSystemClassLoader().getResourceAsStream(resourcePath);
if (in == null) {
return null;
}
File tempFile = File.createTempFile(String.valueOf(in.hashCode()), ".tmp");
tempFile.deleteOnExit();
try (FileOutputStream out = new FileOutputStream(tempFile)) {
//copy stream
byte[] buffer = new byte[1024];
int bytesRead;
while ((bytesRead = in.read(buffer)) != -1) {
out.write(buffer, 0, bytesRead);
}
}
return tempFile;
} catch (IOException e) {
e.printStackTrace();
return null;
}
}
I tried the following three methods, my file size is 1M, and I got results:
I run the program several times it looks that BufferedReader is faster.
@Test
public void testLargeFileIO_Scanner() throws Exception {
long start = new Date().getTime();
String fileName = "/Downloads/SampleTextFile_1000kb.txt"; //this path is on my local
InputStream inputStream = new FileInputStream(fileName);
try (Scanner fileScanner = new Scanner(inputStream, StandardCharsets.UTF_8.name())) {
while (fileScanner.hasNextLine()) {
String line = fileScanner.nextLine();
//System.out.println(line);
}
}
long end = new Date().getTime();
long time = end - start;
System.out.println("Scanner Time Consumed => " + time);
}
@Test
public void testLargeFileIO_BufferedReader() throws Exception {
long start = new Date().getTime();
String fileName = "/Downloads/SampleTextFile_1000kb.txt"; //this path is on my local
try (BufferedReader fileBufferReader = new BufferedReader(new FileReader(fileName))) {
String fileLineContent;
while ((fileLineContent = fileBufferReader.readLine()) != null) {
//System.out.println(fileLineContent);
}
}
long end = new Date().getTime();
long time = (long) (end - start);
System.out.println("BufferedReader Time Consumed => " + time);
}
@Test
public void testLargeFileIO_Stream() throws Exception {
long start = new Date().getTime();
String fileName = "/Downloads/SampleTextFile_1000kb.txt"; //this path is on my local
try (Stream inputStream = Files.lines(Paths.get(fileName), StandardCharsets.UTF_8)) {
//inputStream.forEach(System.out::println);
}
long end = new Date().getTime();
long time = end - start;
System.out.println("Stream Time Consumed => " + time);
}
Posting parameters Using POST:-
URL url;
URLConnection urlConn;
DataOutputStream printout;
DataInputStream input;
url = new URL (getCodeBase().toString() + "env.tcgi");
urlConn = url.openConnection();
urlConn.setDoInput (true);
urlConn.setDoOutput (true);
urlConn.setUseCaches (false);
urlConn.setRequestProperty("Content-Type","application/json");
urlConn.setRequestProperty("Host", "android.schoolportal.gr");
urlConn.connect();
//Create JSONObject here
JSONObject jsonParam = new JSONObject();
jsonParam.put("ID", "25");
jsonParam.put("description", "Real");
jsonParam.put("enable", "true");
The part which you missed is in the the following... i.e., as follows..
// Send POST output.
printout = new DataOutputStream(urlConn.getOutputStream ());
printout.writeBytes(URLEncoder.encode(jsonParam.toString(),"UTF-8"));
printout.flush ();
printout.close ();
The rest of the thing you can do it.
The fields of your object have in turn their fields, some of which do not implement Serializable

You seem to have used some [Authorize]
attribute on your Web API controller action and I don't see how this is relevant to your question.
So, let's get into practice. Here's a how a trivial Web API controller might look like:
public class TestController : ApiController
{
public string Post([FromBody] string value)
{
return value;
}
}
and a consumer for that matter:
class Program
{
static void Main()
{
using (var client = new WebClient())
{
client.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded";
var data = "=Short test...";
var result = client.UploadString("http://localhost:52996/api/test", "POST", data);
Console.WriteLine(result);
}
}
}
You will undoubtedly notice the [FromBody]
decoration of the Web API controller attribute as well as the =
prefix of the POST data om the client side. I would recommend you reading about how does the Web API does parameter binding to better understand the concepts.
As far as the [Authorize]
attribute is concerned, this could be used to protect some actions on your server from being accessible only to authenticated users. Actually it is pretty unclear what you are trying to achieve here.You should have made this more clear in your question by the way. Are you are trying to understand how parameter bind works in ASP.NET Web API (please read the article I've linked to if this is your goal) or are attempting to do some authentication and/or authorization? If the second is your case you might find the following post
that I wrote on this topic interesting to get you started.
And if after reading the materials I've linked to, you are like me and say to yourself, WTF man, all I need to do is POST a string to a server side endpoint and I need to do all of this? No way. Then checkout ServiceStack. You will have a good base for comparison with Web API. I don't know what the dudes at Microsoft were thinking about when designing the Web API, but come on, seriously, we should have separate base controllers for our HTML (think Razor) and REST stuff? This cannot be serious.
You can use HttpPost, there are methods to add Header to the Request.
DefaultHttpClient httpclient = new DefaultHttpClient();
String url = "http://localhost";
HttpPost httpPost = new HttpPost(url);
httpPost.addHeader("header-name" , "header-value");
HttpResponse response = httpclient.execute(httpPost);
I also came across the same issue. I was trying to build the project with a clean install
goal. I simply changed it to clean package -o
in the run configuration. Then I re-built the project and it worked for me.
This is overly complicated, Jackson handles lists via its writer methods just as well as it handles regular objects. This should work just fine for you, assuming I have not misunderstood your question:
public void writeListToJsonArray() throws IOException {
final List<Event> list = new ArrayList<Event>(2);
list.add(new Event("a1","a2"));
list.add(new Event("b1","b2"));
final ByteArrayOutputStream out = new ByteArrayOutputStream();
final ObjectMapper mapper = new ObjectMapper();
mapper.writeValue(out, list);
final byte[] data = out.toByteArray();
System.out.println(new String(data));
}
// take variable of imageview
private ImageView mImageView;
//bind imageview with your xml's id
mImageView = (ImageView)findViewById(R.id.mImageView);
//set resource for imageview
mImageView.setImageResource(R.drawable.your_image_name);
I assume the question is already answered. If above solution doesn't help in solving the issue then can use below to solve the issue.
The issue occurs if sometimes your maven user settings is not reflecting correct settings.xml file.
To update the settings file go to Windows > Preferences > Maven > User Settings and update the settings.xml to it correct location.
Once this is doen re-build the project, these should solve the issue. Thanks.
The problem id because of inp.read();
method. Its return single character at a time and because you are storing it into int type of array so that is just storing ascii value of that.
What you can do simply
for(int i=0;i<T;i++) {
String s= inp.readLine();
String[] intValues = inp.readLine().split(" ");
int[] m= new int[2];
m[0]=Integer.parseInt(intValues[0]);
m[1]=Integer.parseInt(intValues[1]);
// Checking whether I am taking the inputs correctly
System.out.println(s);
System.out.println(m[0]);
System.out.println(m[1]);
}
also very comprehensive...
try{
InputStream fis=new FileInputStream(targetsFile);
BufferedReader br=new BufferedReader(new InputStreamReader(fis));
for (String line = br.readLine(); line != null; line = br.readLine()) {
System.out.println(line);
}
br.close();
}
catch(Exception e){
System.err.println("Error: Target File Cannot Be Read");
}
Looking at Biju's answer I found a working solution.
I created an extra context-file test-context.xml
:
<context:property-placeholder location="classpath:config/spring-test.properties"/>
Containing the profile:
spring.profiles.active=localtest
And loading the test with:
@RunWith(SpringJUnit4ClassRunner.class)
@TestExecutionListeners({
TestPreperationExecutionListener.class
})
@Transactional
@ActiveProfiles(profiles = "localtest")
@ContextConfiguration(locations = {
"classpath:config/test-context.xml" })
public class TestContext {
@Test
public void testContext(){
}
}
This saves some work when creating multiple test-cases.
Otherwise Try this :
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
public class Temp {
public static void main(String[] args) {
File file = new File("c:/EventItemBroker.java");
byte[] b = new byte[(int) file.length()];
try {
FileInputStream fileInputStream = new FileInputStream(file);
fileInputStream.read(b);
for (int i = 0; i < b.length; i++) {
System.out.print((char)b[i]);
}
} catch (FileNotFoundException e) {
System.out.println("File Not Found.");
e.printStackTrace();
}
catch (IOException e1) {
System.out.println("Error Reading The File.");
e1.printStackTrace();
}
}
}
public class WriteByteArrayToFile {
public static void main(String[] args) {
String strFilePath = "Your path";
try {
FileOutputStream fos = new FileOutputStream(strFilePath);
String strContent = "Write File using Java ";
fos.write(strContent.getBytes());
fos.close();
}
catch(FileNotFoundException ex) {
System.out.println("FileNotFoundException : " + ex);
}
catch(IOException ioe) {
System.out.println("IOException : " + ioe);
}
}
}
The file you read in must have exactly the file name you specify: "10_random"
not "10_random.txt" not "10_random.blah", it must exactly match what you are asking for. You can change either one to match so that they line up, but just be sure they do. It may help to show the file extensions in whatever OS you're using.
Also, for file location, it must be located in the working directory (same level) as the final executable (the .class file) that is the result of compilation.
Or
Navigate to project root folder and use following commands :
mvn clean install -U or mvn clean install --update-snapshots
Here -U will Forces a check for missing releases and updated snapshots on remote repositories
Arrays of data are converted into csv 'text/csv' format by built in php function fputcsv takes care of commas, quotes and etc..
Look at
https://coderwall.com/p/zvzwwa/array-to-comma-separated-string-in-php
http://www.php.net/manual/en/function.fputcsv.php
As per your requirement, Thread.Sleep
is perfectly fine to use because you are not sure when the data will be available so you might need to wait for the data to become available. I have slightly changed the logic of your function this might help you little further.
string SendCmd(string cmd, string ip, int port)
{
var client = new TcpClient(ip, port);
var data = Encoding.GetEncoding(1252).GetBytes(cmd);
var stm = client.GetStream();
stm.Write(data, 0, data.Length);
byte[] resp = new byte[2048];
var memStream = new MemoryStream();
int bytes = 0;
do
{
bytes = 0;
while (!stm.DataAvailable)
Thread.Sleep(20); // some delay
bytes = stm.Read(resp, 0, resp.Length);
memStream.Write(resp, 0, bytes);
}
while (bytes > 0);
return Encoding.GetEncoding(1252).GetString(memStream.ToArray());
}
Hope this helps!
The reason why you don't have to load a certificate locally is that you've explicitly chosen not to verify the certificate, with this trust manager that trusts all certificates.
The traffic will still be encrypted, but you're opening the connection to Man-In-The-Middle attacks: you're communicating secretly with someone, you're just not sure whether it's the server you expect, or a possible attacker.
If your server certificate comes from a well-known CA, part of the default bundle of CA certificates bundled with the JRE (usually cacerts
file, see JSSE Reference guide), you can just use the default trust manager, you don't have to set anything here.
If you have a specific certificate (self-signed or from your own CA), you can use the default trust manager or perhaps one initialised with a specific truststore, but you'll have to import the certificate explicitly in your trust store (after independent verification), as described in this answer. You may also be interested in this answer.
The correct way to 'solve' it is to close the connection and forget about the client. The client has closed the connection while you where still writing to it, so he doesn't want to know you, so that's it, isn't it?
I had this issue with npm v1.1.4
(and node v0.6.12
), which are the Ubuntu 12.04
repository versions.
It looks like that version of npm
isn't supported any more, updating node (and npm with it) resolved the issue.
First, uninstall the outdated version (optional, but I think this fixed an issue I was having with global modules not being pathed in).
sudo apt-get purge nodejs npm
Then enable nodesource's repo and install:
curl -sL https://deb.nodesource.com/setup | sudo bash -
sudo apt-get install -y nodejs
Note - the previous advice was to use Chris Lea's repo, he's now migrated that to nodesource, see:
From: here

logger.error("Failed to read the xml : ", e);
}

You can try this it will recursively find all key values in a json object and constructs as a map . You can simply get which key you want from the Map .
public static Map<String,String> parse(JSONObject json , Map<String,String> out) throws JSONException{
Iterator<String> keys = json.keys();
while(keys.hasNext()){
String key = keys.next();
String val = null;
try{
JSONObject value = json.getJSONObject(key);
parse(value,out);
}catch(Exception e){
val = json.getString(key);
}
if(val != null){
out.put(key,val);
}
}
return out;
}
public static void main(String[] args) throws JSONException {
String json = "{'ipinfo': {'ip_address': '131.208.128.15','ip_type': 'Mapped','Location': {'continent': 'north america','latitude': 30.1,'longitude': -81.714,'CountryData': {'country': 'united states','country_code': 'us'},'region': 'southeast','StateData': {'state': 'florida','state_code': 'fl'},'CityData': {'city': 'fleming island','postal_code': '32003','time_zone': -5}}}}";
JSONObject object = new JSONObject(json);
JSONObject info = object.getJSONObject("ipinfo");
Map<String,String> out = new HashMap<String, String>();
parse(info,out);
String latitude = out.get("latitude");
String longitude = out.get("longitude");
String city = out.get("city");
String state = out.get("state");
String country = out.get("country");
String postal = out.get("postal_code");
System.out.println("Latitude : " + latitude + " LongiTude : " + longitude + " City : "+city + " State : "+ state + " Country : "+country+" postal "+postal);
System.out.println("ALL VALUE " + out);
}
Output:
Latitude : 30.1 LongiTude : -81.714 City : fleming island State : florida Country : united states postal 32003
ALL VALUE {region=southeast, ip_type=Mapped, state_code=fl, state=florida, country_code=us, city=fleming island, country=united states, time_zone=-5, ip_address=131.208.128.15, postal_code=32003, continent=north america, longitude=-81.714, latitude=30.1}
This example made everything clear for me:
As you can see setSoTimeout prevent the program to hang! It wait for SO_TIMEOUT
time! if it does not get any signal it throw exception! It means that time expired!

Probably going overboard a bit but i provided call backs for both the execution code and the results. obviously for thread safety you want to be careful what you access in your execution callback.
The AsyncTask implementation:
public class AsyncDbCall<ExecuteType,ResultType> extends AsyncTask<ExecuteType, Void,
ResultType>
{
public interface ExecuteCallback<E, R>
{
public R execute(E executeInput);
}
public interface PostExecuteCallback<R>
{
public void finish(R result);
}
private PostExecuteCallback<ResultType> _resultCallback = null;
private ExecuteCallback<ExecuteType,ResultType> _executeCallback = null;
AsyncDbCall(ExecuteCallback<ExecuteType,ResultType> executeCallback, PostExecuteCallback<ResultType> postExecuteCallback)
{
_resultCallback = postExecuteCallback;
_executeCallback = executeCallback;
}
AsyncDbCall(ExecuteCallback<ExecuteType,ResultType> executeCallback)
{
_executeCallback = executeCallback;
}
@Override
protected ResultType doInBackground(final ExecuteType... params)
{
return _executeCallback.execute(params[0]);
}
@Override
protected void onPostExecute(ResultType result)
{
if(_resultCallback != null)
_resultCallback.finish(result);
}
}
A callback:
AsyncDbCall.ExecuteCallback<Device, Device> updateDeviceCallback = new
AsyncDbCall.ExecuteCallback<Device, Device>()
{
@Override
public Device execute(Device device)
{
deviceDao.updateDevice(device);
return device;
}
};
And finally execution of the async task:
new AsyncDbCall<>(addDeviceCallback, resultCallback).execute(device);
Expressed explicitly ...
ServicePointManager.ServerCertificateValidationCallback += new System.Net.Security.RemoteCertificateValidationCallback(CertCheck);
private static bool CertCheck(object sender, X509Certificate cert,
X509Chain chain, System.Net.Security.SslPolicyErrors error)
{
return true;
}
First you store your text file in to raw folder.
private void loadWords() throws IOException {
Log.d(TAG, "Loading words...");
final Resources resources = mHelperContext.getResources();
InputStream inputStream = resources.openRawResource(R.raw.definitions);
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
try {
String line;
while ((line = reader.readLine()) != null) {
String[] strings = TextUtils.split(line, "-");
if (strings.length < 2)
continue;
long id = addWord(strings[0].trim(), strings[1].trim());
if (id < 0) {
Log.e(TAG, "unable to add word: " + strings[0].trim());
}
}
} finally {
reader.close();
}
Log.d(TAG, "DONE loading words.");
}
First cast your Edit text like this:
TextView tekst = (TextView) findViewById(R.id.editText1);
tekst.setText(text);
And after that close the DB not befor this line...
myDataBaseHelper.close();
Whenever you're confused, I would suggest consulting the Javadoc as the first place for your clarification.
From the javadoc about System
, here's what the doc says:
public final class System
extends Object
The System class contains several useful class fields and methods. It cannot be instantiated.
Among the facilities provided by the System class are standard input, standard output, and error output streams; access to externally defined properties and environment variables; a means of loading files and libraries; and a utility method for quickly copying a portion of an array.
Since:
JDK1.0
Regarding System.out
public static final PrintStream out
The "standard" output stream. This stream is already open and ready to accept output data. Typically this stream corresponds to display output or another output destination specified by the host environment or user.
For simple stand-alone Java applications, a typical way to write a line of output data is:
System.out.println(data)
As of October 2014, you can just do something like the following (using JSONStream) - https://www.npmjs.org/package/JSONStream
var fs = require('fs'),
JSONStream = require('JSONStream'),
var getStream() = function () {
var jsonData = 'myData.json',
stream = fs.createReadStream(jsonData, { encoding: 'utf8' }),
parser = JSONStream.parse('*');
return stream.pipe(parser);
}
getStream().pipe(MyTransformToDoWhateverProcessingAsNeeded).on('error', function (err) {
// handle any errors
});
To demonstrate with a working example:
npm install JSONStream event-stream
data.json:
{
"greeting": "hello world"
}
hello.js:
var fs = require('fs'),
JSONStream = require('JSONStream'),
es = require('event-stream');
var getStream = function () {
var jsonData = 'data.json',
stream = fs.createReadStream(jsonData, { encoding: 'utf8' }),
parser = JSONStream.parse('*');
return stream.pipe(parser);
};
getStream()
.pipe(es.mapSync(function (data) {
console.log(data);
}));
$ node hello.js
// hello world
I wrote this quick example. It works for me. I only tested it with one dataset with one table inside, but I guess that may be enough for you.
Take into consideration that I treated all cells as String (not even SharedStrings). If you want to use SharedStrings you might need to tweak my sample a bit.
Edit: To make this work it is necessary to add WindowsBase and DocumentFormat.OpenXml references to project.
Enjoy,

I have no idea why the HttpURLConnection
class does not provide any means to send files without having to compose the file wrapper manually. Here's what I ended up doing, but if someone knows a better solution, please let me know.
Input data:
Bitmap bitmap = myView.getBitmap();
Static stuff:
String attachmentName = "bitmap";
String attachmentFileName = "bitmap.bmp";
String crlf = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
Setup the request:
HttpURLConnection httpUrlConnection = null;
URL url = new URL("http://example.com/server.cgi");
httpUrlConnection = (HttpURLConnection) url.openConnection();
httpUrlConnection.setUseCaches(false);
httpUrlConnection.setDoOutput(true);
httpUrlConnection.setRequestMethod("POST");
httpUrlConnection.setRequestProperty("Connection", "Keep-Alive");
httpUrlConnection.setRequestProperty("Cache-Control", "no-cache");
httpUrlConnection.setRequestProperty(
"Content-Type", "multipart/form-data;boundary=" + this.boundary);
Start content wrapper:
DataOutputStream request = new DataOutputStream(
httpUrlConnection.getOutputStream());
request.writeBytes(this.twoHyphens + this.boundary + this.crlf);
request.writeBytes("Content-Disposition: form-data; name=\"" +
this.attachmentName + "\";filename=\"" +
this.attachmentFileName + "\"" + this.crlf);
request.writeBytes(this.crlf);
Convert Bitmap
to ByteBuffer
:
//I want to send only 8 bit black & white bitmaps
byte[] pixels = new byte[bitmap.getWidth() * bitmap.getHeight()];
for (int i = 0; i < bitmap.getWidth(); ++i) {
for (int j = 0; j < bitmap.getHeight(); ++j) {
//we're interested only in the MSB of the first byte,
//since the other 3 bytes are identical for B&W images
pixels[i + j] = (byte) ((bitmap.getPixel(i, j) & 0x80) >> 7);
}
}
request.write(pixels);
End content wrapper:
request.writeBytes(this.crlf);
request.writeBytes(this.twoHyphens + this.boundary +
this.twoHyphens + this.crlf);
Flush output buffer:
request.flush();
request.close();
Get response:
InputStream responseStream = new
BufferedInputStream(httpUrlConnection.getInputStream());
BufferedReader responseStreamReader =
new BufferedReader(new InputStreamReader(responseStream));
String line = "";
StringBuilder stringBuilder = new StringBuilder();
while ((line = responseStreamReader.readLine()) != null) {
stringBuilder.append(line).append("\n");
}
responseStreamReader.close();
String response = stringBuilder.toString();
Close response stream:
responseStream.close();
Close the connection:
httpUrlConnection.disconnect();
PS: Of course I had to wrap the request in private class AsyncUploadBitmaps extends AsyncTask<Bitmap, Void, String>
, in order to make the Android platform happy, because it doesn't like to have network requests on the main thread.
Put the text file in the assets directory. If there isnt an assets dir create one in the root of the project. Then you can use Context.getAssets().open("BlockForTest.txt");
to open a stream to this file.
Someone should mark Johannes Weiß's comment as the answer to this question. That is exactly why xml documents can't just be loaded in a DOM Document class.
You need to give the absolute pathname to where the file exists.
File file = new File("C:\\Users\\User\\Documents\\Workspace\\FileRead\\hello.txt");
If you do not want to use other library, here is a simple function to convert InputStream
to OutputStream
.
public static void copyStream(InputStream in, OutputStream out) throws IOException {
byte[] buffer = new byte[1024];
int read;
while ((read = in.read(buffer)) != -1) {
out.write(buffer, 0, read);
}
}
Now you can easily write an Inputstream
into file by using FileOutputStream
-
FileOutputStream out = new FileOutputStream(outFile);
copyStream (inputStream, out);
out.close();
Below is the relevant information from the link which Zaki provided.

new X509EncodedKeySpec(keyBytes);
KeyFactory kf = KeyFactory.getInstance("RSA");
return kf.generatePublic(spec);
}
}
Two example works for me, for your reference.
Bitmap bitmap = Utils.decodeBase64(base64);
try {
File file = new File(filePath);
FileOutputStream fOut = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.PNG, 85, fOut);
fOut.flush();
fOut.close();
}
catch (Exception e) {
e.printStackTrace();
LOG.i(null, "Save file error!");
return false;
}
and this one
Bitmap savePic = Utils.decodeBase64(base64);
File file = new File(filePath);
File path = new File(file.getParent());
if (savePic != null) {
try {
// build directory
if (file.getParent() != null && !path.isDirectory()) {
path.mkdirs();
}
// output image to file
FileOutputStream fos = new FileOutputStream(filePath);
savePic.compress(Bitmap.CompressFormat.PNG, 90, fos);
fos.close();
ret = true;
} catch (Exception e) {
e.printStackTrace();
}
} else {
LOG.i(TAG, "savePicture image parsing error");
}
Uninstalling the app on device and then reinstalling fixed it for me.
Tried all the other options, nothing. Finally found this post. This is after adding permission (below) and cleaning build.
<uses-permission android:name="android.permission.INTERNET"/>
Just wanted to point out another reason this error can be thrown is if you defined a string resource for one translation of your app but did not provide a default string resource.
As you can see below, I had a string resource for a Spanish string "get_started". It can still be referenced in code, but if the phone is not in Spanish it will have no resource to load and crash when calling getString()
.
values-es/strings.xml
<string name="get_started">SIGUIENTE</string>
Reference to resource
textView.setText(getString(R.string.get_started)

Preventing this is quite simple, just make sure that you always have a default string resource in values/strings.xml
so that if the phone is in another language it will always have a resource to fall back to.
values/strings.xml
<string name="get_started">Get Started</string>
values-en/strings.xml
<string name="get_started">Get Started</string>
values-es/strings.xml
<string name="get_started">Siguiente</string>
values-de/strings.xml
<string name="get_started">Ioslegen</string>
You will have to download file from here https://commons.apache.org/proper/commons-io/download_io.cgi and select https://prnt.sc/tk5ewt
Now, Next add this downloaded files into your project:
Right click to your project ->Build path->Configure BuidPath -> https://prnt.sc/tk5d93
In case you need to add a fence of 1s to an array:
>>> mat = np.zeros((4,4), np.int32)
>>> mat
array([[0, 0, 0, 0],
[0, 0, 0, 0],
[0, 0, 0, 0],
[0, 0, 0, 0]])
>>> mat[0,:] = mat[:,0] = mat[:,-1] = mat[-1,:] = 1
>>> mat
array([[1, 1, 1, 1],
[1, 0, 0, 1],
[1, 0, 0, 1],
[1, 1, 1, 1]])
This is pretty much as close as you'll get if you want to use the ActionBar
APIs. I'm not sure you can place a colorstrip above the ActionBar
without doing some weird Window
hacking, it's not worth the trouble. As far as changing the MenuItems
goes, you can make those tighter via a style. It would be something like this, but I haven't tested it.
<style name="MyTheme" parent="android:Theme.Holo.Light">
<item name="actionButtonStyle">@style/MyActionButtonStyle</item>
</style>
<style name="MyActionButtonStyle" parent="Widget.ActionButton">
<item name="android:minWidth">28dip</item>
</style>
Here's how to inflate and add the custom layout to your ActionBar
.
// Inflate your custom layout
final ViewGroup actionBarLayout = (ViewGroup) getLayoutInflater().inflate(
R.layout.action_bar,
null);
// Set up your ActionBar
final ActionBar actionBar = getActionBar();
actionBar.setDisplayShowHomeEnabled(false);
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setDisplayShowCustomEnabled(true);
actionBar.setCustomView(actionBarLayout);
// You customization
final int actionBarColor = getResources().getColor(R.color.action_bar);
actionBar.setBackgroundDrawable(new ColorDrawable(actionBarColor));
final Button actionBarTitle = (Button) findViewById(R.id.action_bar_title);
actionBarTitle.setText("Index(2)");
final Button actionBarSent = (Button) findViewById(R.id.action_bar_sent);
actionBarSent.setText("Sent");
final Button actionBarStaff = (Button) findViewById(R.id.action_bar_staff);
actionBarStaff.setText("Staff");
final Button actionBarLocations = (Button) findViewById(R.id.action_bar_locations);
actionBarLocations.setText("HIPPA Locations");
Here's the custom layout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:enabled="false"
android:orientation="horizontal"
android:paddingEnd="8dip" >
<Button
android:id="@+id/action_bar_title"
style="@style/ActionBarButtonWhite" />
<Button
android:id="@+id/action_bar_sent"
style="@style/ActionBarButtonOffWhite" />
<Button
android:id="@+id/action_bar_staff"
style="@style/ActionBarButtonOffWhite" />
<Button
android:id="@+id/action_bar_locations"
style="@style/ActionBarButtonOffWhite" />
</LinearLayout>
Here's the color strip layout: To use it, just use merge
in whatever layout you inflate in setContentView
.
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="@dimen/colorstrip"
android:background="@android:color/holo_blue_dark" />
Here are the Button
styles:
<style name="ActionBarButton">
<item name="android:layout_width">wrap_content</item>
<item name="android:layout_height">wrap_content</item>
<item name="android:background">@null</item>
<item name="android:ellipsize">end</item>
<item name="android:singleLine">true</item>
<item name="android:textSize">@dimen/text_size_small</item>
</style>
<style name="ActionBarButtonWhite" parent="@style/ActionBarButton">
<item name="android:textColor">@color/white</item>
</style>
<style name="ActionBarButtonOffWhite" parent="@style/ActionBarButton">
<item name="android:textColor">@color/off_white</item>
</style>
Here are the colors and dimensions I used:
<color name="action_bar">#ff0d0d0d</color>
<color name="white">#ffffffff</color>
<color name="off_white">#99ffffff</color>
<!-- Text sizes -->
<dimen name="text_size_small">14.0sp</dimen>
<dimen name="text_size_medium">16.0sp</dimen>
<!-- ActionBar color strip -->
<dimen name="colorstrip">5dp</dimen>
If you want to customize it more than this, you may consider not using the ActionBar
at all, but I wouldn't recommend that. You may also consider reading through the Android Design Guidelines to get a better idea on how to design your ActionBar.
If you choose to forgo the ActionBar
and use your own layout instead, you should be sure to add action-able Toasts
when users long press your "MenuItems". This can be easily achieved using this Gist.
The accepted answer does not work in Jupyter (at least when using some libraries).
The Javascript solutions here only hide warnings that are already showing but not warnings that would be shown in the future.
To hide/unhide warnings in Jupyter and JupyterLab I wrote the following script that essentially toggles css to hide/unhide warnings.
%%javascript
(function(on) {
const e=$( "<a>Setup failed</a>" );
const ns="js_jupyter_suppress_warnings";
var cssrules=$("#"+ns);
if(!cssrules.length) cssrules = $("<style id='"+ns+"' type='text/css'>div.output_stderr { } </style>").appendTo("head");
e.click(function() {
var s='Showing';
cssrules.empty()
if(on) {
s='Hiding';
cssrules.append("div.output_stderr, div[data-mime-type*='.stderr'] { display:none; }");
}
e.text(s+' warnings (click to toggle)');
on=!on;
}).click();
$(element).append(e);
})(true);
.catch(error => { throw error})
is a no-op. It results in unhandled rejection in route handler.
As explained in this answer, Express doesn't support promises, all rejections should be handled manually:
router.get("/emailfetch", authCheck, async (req, res, next) => {
try {
//listing messages in users mailbox
let emailFetch = await gmaiLHelper.getEmails(req.user._doc.profile_id , '/messages', req.user.accessToken)
emailFetch = emailFetch.data
res.send(emailFetch)
} catch (err) {
next(err);
}
})
I'd probably change your example to look like this:
<ul ng-repeat="task in tasks">
<li ng-mouseover="enableEdit(task)" ng-mouseleave="disableEdit(task)">{{task.name}}</li>
<span ng-show="task.editable"><a>Edit</a></span>
</ul>
//js
$scope.enableEdit = function(item){
item.editable = true;
};
$scope.disableEdit = function(item){
item.editable = false;
};
I know it's a subtle difference, but makes the domain a little less bound to UI actions. Mentally it makes it easier to think about an item being editable rather than having been moused over.

You have to replace string line
QString line = in.readLine();
into while:
QFile file("/home/hamad/lesson11.txt");
if(!file.open(QIODevice::ReadOnly)) {
QMessageBox::information(0, "error", file.errorString());
}
QTextStream in(&file);
while(!in.atEnd()) {
QString line = in.readLine();
QStringList fields = line.split(",");
model->appendRow(fields);
}
file.close();
try something like :
var focusout = false;
$("#Button1").click(function () {
if (focusout == true) {
focusout = false;
return;
}
else {
GetInfo();
}
});
$("#Text1").focusout(function () {
focusout = true;
GetInfo();
});
I would (and have) started to use Dapper. To use your example would be like (written from memory):
public List<CustomerEntity> GetCustomerList()
{
using (DbConnection connection = CreateConnection())
{
return connection.Query<CustomerEntity>("procToReturnCustomers", commandType: CommandType.StoredProcedure).ToList();
}
}
CreateConnection()
would handle accessing your db and returning a connection.
Dapper handles mapping datafields to properties automatically. It also supports multiple types and result sets and is very fast.
Query returns IEnumerable
hence the ToList()
.
Try this code. It will work
Uri smsUri = Uri.parse("tel:123456");
Intent intent = new Intent(Intent.ACTION_VIEW, smsUri);
intent.putExtra("sms_body", "sms text");
intent.setType("vnd.android-dir/mms-sms");
startActivity(intent);
Hope this will help you.
As the existing answers mentioned, LEA
has the advantages of performing memory addressing arithmetic without accessing memory, saving the arithmetic result to a different register instead of the simple form of add instruction. The real underlying performance benefit is that modern processor has a separate LEA ALU unit and port for effective address generation (including LEA
and other memory reference address), this means the arithmetic operation in LEA
and other normal arithmetic operation in ALU could be done in parallel in one core.
Check this article of Haswell architecture for some details about LEA unit: http://www.realworldtech.com/haswell-cpu/4/
Another important point which is not mentioned in other answers is LEA REG, [MemoryAddress]
instruction is PIC (position independent code) which encodes the PC relative address in this instruction to reference MemoryAddress
. This is different from MOV REG, MemoryAddress
which encodes relative virtual address and requires relocating/patching in modern operating systems (like ASLR is common feature). So LEA
can be used to convert such non PIC to PIC.
This will work for refresh parent window from child window
window.opener.location.reload(true);
for some version of IE this will not work so you can set some delay
window.setTimeout(window.opener.location.reload(true), 3000);
In the absence of the ability to do zone transfers, I wrote this small bash script, dg
:
#!/bin/bash
COMMON_SUBDOMAINS=(www mail smtp pop imap blog en ftp ssh login)
if [[ "$2" == "x" ]]; then
dig +nocmd "$1" +noall +answer "${3:-any}"
wild_ips="$(dig +short "*.$1" "${3:-any}" | tr '\n' '|')"
wild_ips="${wild_ips%|}"
for sub in "${COMMON_SUBDOMAINS[@]}"; do
dig +nocmd "$sub.$1" +noall +answer "${3:-any}"
done | grep -vE "${wild_ips}"
dig +nocmd "*.$1" +noall +answer "${3:-any}"
else
dig +nocmd "$1" +noall +answer "${2:-any}"
fi
Now I use dg example.com
to get a nice, clean list of DNS records, or dg example.com x
to include a bunch of other popular subdomains.
grep -vE "${wild_ips}"
filters out records that could be the result of a wildcard DNS entry such as * 10800 IN A 1.38.216.82
. Otherwise, a wildcard entry would make it appear as if there were records for each $COMMON_SUBDOMAN
.
Note: This relies on ANY
queries, which are blocked by some DNS providers such as CloudFlare.
//set vars
$user = $_POST['user'];
$pass = md5($_POST['pass']);
if ($user&&$pass)
{
//connect to db
$connect = mysql_connect("$server","$username","$password") or die("not connecting");
mysql_select_db("users") or die("no db :'(");
$query = mysql_query("SELECT * FROM $tablename WHERE username='$user'");
$numrows = mysql_num_rows($query);
if ($numrows!=0)
{
//while loop
while ($row = mysql_fetch_assoc($query))
{
$dbusername = $row['username'];
$dbpassword = $row['password'];
}
else
die("incorrect username/password!");
}
else
echo "user does not exist!";
}
else
die("please enter a username and password!");
>>> x = "2342.34"
>>> float(x)
2342.3400000000001
There you go. Use float (which behaves like and has the same precision as a C,C++, or Java double).
A simple, but not pure java solution, is to shell out to curl
from java, which gives you complete control over how the request is done. If you're just doing this for something simple, this allows you to ignore certificate errors at times, by using this method. This example shows how to make a request against a secure server with a valid or invalid certificate, pass in a cookie, and get the output using curl
from java.
import java.io.BufferedReader;
import java.io.File;
import java.io.IOException;
import java.io.InputStreamReader;
public class MyTestClass
{
public static void main(String[] args)
{
String url = "https://www.google.com";
String sessionId = "faf419e0-45a5-47b3-96d1-8c62b2a3b558";
// Curl options are:
// -k: ignore certificate errors
// -L: follow redirects
// -s: non verbose
// -H: add a http header
String[] command = { "curl", "-k", "-L", "-s", "-H", "Cookie: MYSESSIONCOOKIENAME=" + sessionId + ";", "-H", "Accept:*/*", url };
String output = executeShellCmd(command, "/tmp", true, true);
System.out.println(output);
}
public String executeShellCmd(String[] command, String workingFolder, boolean wantsOutput, boolean wantsErrors)
{
try
{
ProcessBuilder pb = new ProcessBuilder(command);
File wf = new File(workingFolder);
pb.directory(wf);
Process proc = pb.start();
BufferedReader stdInput = new BufferedReader(new InputStreamReader(proc.getInputStream()));
BufferedReader stdError = new BufferedReader(new InputStreamReader(proc.getErrorStream()));
StringBuffer sb = new StringBuffer();
String newLine = System.getProperty("line.separator");
String s;
// read stdout from the command
if (wantsOutput)
{
while ((s = stdInput.readLine()) != null)
{
sb.append(s);
sb.append(newLine);
}
}
// read any errors from the attempted command
if (wantsErrors)
{
while ((s = stdError.readLine()) != null)
{
sb.append(s);
sb.append(newLine);
}
}
String result = sb.toString();
return result;
}
catch (IOException e)
{
throw new RuntimeException("Problem occurred:", e);
}
}
}
Even though --files
is no longer supported, you can use an env variable to provide a list of files:
// karma.conf.js
function getSpecs(specList) {
if (specList) {
return specList.split(',')
} else {
return ['**/*_spec.js'] // whatever your default glob is
}
}
module.exports = function(config) {
config.set({
//...
files: ['app.js'].concat(getSpecs(process.env.KARMA_SPECS))
});
});
Then in CLI:
$ env KARMA_SPECS="spec1.js,spec2.js" karma start karma.conf.js --single-run
use this coding
io.sockets.on('connection', function (socket) {
socket.on('mousemove', function (data) {
socket.broadcast.emit('moving', data);
});
this socket.broadcast.emit() will emit everthing in the function except to the server which is emitting
Call and apply both are used to force the this
value when a function is executed. The only difference is that call
takes n+1
arguments where 1 is this
and 'n' arguments
. apply
takes only two arguments, one is this
the other is argument array.
The advantage I see in apply
over call
is that we can easily delegate a function call to other function without much effort;
function sayHello() {
console.log(this, arguments);
}
function hello() {
sayHello.apply(this, arguments);
}
var obj = {name: 'my name'}
hello.call(obj, 'some', 'arguments');
Observe how easily we delegated hello
to sayHello
using apply
, but with call
this is very difficult to achieve.
From MSDN:
The foreach statement repeats a group of embedded statements for each element in an array or an object collection that implements the System.Collections.IEnumerable or System.Collections.Generic.IEnumerable(Of T) interface.
So, it's not necessarily Array. It could even be a lazy collection with no idea about the count of items in the collection.
Try this instead:
$journalName = preg_replace('/\s+/', '_', $journalName);
Explanation: you are most likely seeing whitespace, not just plain spaces (there is a difference).
You just need to add this property in your asp:Button element (for example):
OnClientClick="javascript:window.close();"
It works perfectly.
You need to do this:
OleDbConnection connection = new OleDbConnection(
"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=Inventar.accdb");
DataSet DS = new DataSet();
connection.Open();
string query =
@"SELECT tbl_Computer.*, tbl_Besitzer.*
FROM tbl_Computer
INNER JOIN tbl_Besitzer ON tbl_Computer.FK_Benutzer = tbl_Besitzer.ID
WHERE (((tbl_Besitzer.Vorname)='ma'))";
OleDbDataAdapter DBAdapter = new OleDbDataAdapter();
DBAdapter.SelectCommand = new OleDbCommand(query, connection);
DBAdapter.Fill(DS);
By the way, what is this DataSet1? This should be "DataSet".
Actually openssl
command is a better tool than curl
for checking and debugging SSL. Here is an example with openssl
:
openssl s_client -showcerts -connect stackoverflow.com:443 < /dev/null
and < /dev/null
is for adding EOL to the STDIN
otherwise it hangs on the Terminal.
But if you liked, you can wrap some useful openssl
commands with curl
(as I did with curly) and make it more human readable like so:
# check if SSL is valid
>>> curly --ssl valid -d stackoverflow.com
Verify return code: 0 (ok)
issuer=C = US
O = Let's Encrypt
CN = R3
subject=CN = *.stackexchange.com
option: ssl
action: valid
status: OK
# check how many days it will be valid
>>> curly --ssl date -d stackoverflow.com
Verify return code: 0 (ok)
from: Tue Feb 9 16:13:16 UTC 2021
till: Mon May 10 16:13:16 UTC 2021

I see that the autoload functions only receive the "full" classname - with all the namespaces preceeding it - in the following two cases:
[a] $a = new The\Full\Namespace\CoolClass();
[b] use The\Full\Namespace as SomeNamespace; (at the top of your source file) followed by $a = new SomeNamespace\CoolClass();
I see that the autoload functions DO NOT receive the full classname in the following case:
[c] use The\Full\Namespace; (at the top of your source file) followed by $a = new CoolClass();
UPDATE: [c] is a mistake and isn't how namespaces work anyway. I can report that, instead of [c], the following two cases also work well:
[d] use The\Full\Namespace; (at the top of your source file) followed by $a = new Namespace\CoolClass();
[e] use The\Full\Namespace\CoolClass; (at the top of your source file) followed by $a = new CoolClass();
Hope this helps.
The following script will give you free bytes on the drive:
@setlocal enableextensions enabledelayedexpansion
@echo off
for /f "tokens=3" %%a in ('dir c:\') do (
set bytesfree=%%a
)
set bytesfree=%bytesfree:,=%
echo %bytesfree%
endlocal && set bytesfree=%bytesfree%
Note that this depends on the output of your dir
command, which needs the last line containing the free space of the format 24 Dir(s) 34,071,691,264 bytes free
. Specifically:
for
loop to detect the line explicitly rather than relying on setting bytesfree
for every line).tokens=
bit to get a different word).,
character (or you can change the substitution from comma to something else).It doesn't pollute your environment namespace, setting only the bytesfree
variable on exit. If your dir
output is different (eg, different locale or language settings), you will need to adjust the script.
I considered with timezone in my Google Docs like this:
timezone = "GMT+" + new Date().getTimezoneOffset()/60
var date = Utilities.formatDate(new Date(), timezone, "yyyy-MM-dd HH:mm"); // "yyyy-MM-dd'T'HH:mm:ss'Z'"
My problem was the Dockerfile.txt needed to be converted to a Unix executable file. Once I did that that error went away.
You may need to remove the .txt portion before doing this, but on a mac go to terminal and cd into the directory where your Dockerfile is and the type
chmod +x "Dockerfile"
And then it will convert your file to a Unix executable file which can then be executed by the Docker build command.
This may have been answered before: Python URLLib / URLLib2 POST.
Your server is likely performing a 302 redirect from http://myserver/post_service
to http://myserver/post_service/
. When the 302 redirect is performed, the request changes from POST to GET (see Issue 1401). Try changing url
to http://myserver/post_service/
.
I've written a controller for handling the logic behind an array of radio buttons. It's open source and on GitHub, check it out!
SET XACT_ABORT ON
instructs SQL Server to rollback the entire transaction and abort the batch when a run-time error occurs. It covers you in cases like a command timeout occurring on the client application rather than within SQL Server itself (which isn't covered by the default XACT_ABORT OFF
setting.)
Since a query timeout will leave the transaction open, SET XACT_ABORT ON
is recommended in all stored procedures with explicit transactions (unless you have a specific reason to do otherwise) as the consequences of an application performing work on a connection with an open transaction are disastrous.
There's a really great overview on Dan Guzman's Blog,
Maybe I missed it, but I couldn't find a complete answer on this page to the original question(s) because variables are not further discussed here. So I had to go on searching.
Since I'm not yet allowed to comment, let me add my conclusion here. I'm sure I was not the only one interested in it when accessing this page:
>>>myString = 'Hello World'
>>>end = 5
>>>myString[2:end]
'llo'
If you leave the first part, you get
>>>myString[:end]
'Hello'
And if you left the : in the middle as well you got the simplest substring, which would be the 5th character (count starting with 0, so it's the blank in this case):
>>>myString[end]
' '
If you want to execute that command, you should probably change:
PROCESS_NUM='ps -ef | grep "$1" | grep -v "grep" | wc -l'
to:
PROCESS_NUM=$(ps -ef | grep "$1" | grep -v "grep" | wc -l)
The problem must be that the resource-bunde > base-name attribute at the faces-config.xml file has a different path to your properties. This happened to me on the firstcup Java EE tutorial, I gave a different package name on then project creation and then Glassfish was unable to find the properties folder which is on "firstcup.web".
I hope it helps.
Path is a new feature of Django 2.0. Explained here : https://docs.djangoproject.com/en/2.0/releases/2.0/#whats-new-2-0
Look like more pythonic way, and enable to not use regular expression in argument you pass to view... you can ue int() function for exemple.
The ::
are used to dereference scopes.
const int x = 5;
namespace foo {
const int x = 0;
}
int bar() {
int x = 1;
return x;
}
struct Meh {
static const int x = 2;
}
int main() {
std::cout << x; // => 5
{
int x = 4;
std::cout << x; // => 4
std::cout << ::x; // => 5, this one looks for x outside the current scope
}
std::cout << Meh::x; // => 2, use the definition of x inside the scope of Meh
std::cout << foo::x; // => 0, use the definition of x inside foo
std::cout << bar(); // => 1, use the definition of x inside bar (returned by bar)
}
unrelated: cout and cin are not functions, but instances of stream objects.
EDIT fixed as Keine Lust suggested
To filter a list of dicts you can use the selectattr filter together with the equalto test:
network.addresses.private_man | selectattr("type", "equalto", "fixed")
The above requires Jinja2 v2.8 or later (regardless of Ansible version).
Ansible also has the tests match
and search
, which take regular expressions:
match
will require a complete match in the string, whilesearch
will require a match inside of the string.
network.addresses.private_man | selectattr("type", "match", "^fixed$")
To reduce the list of dicts to a list of strings, so you only get a list of the addr
fields, you can use the map filter:
... | map(attribute='addr') | list
Or if you want a comma separated string:
... | map(attribute='addr') | join(',')
Combined, it would look like this.
- debug: msg={{ network.addresses.private_man | selectattr("type", "equalto", "fixed") | map(attribute='addr') | join(',') }}
I just created my simple enumeration
val args: Array[String] = "-silent -samples 100 -silent".split(" +").toArray
//> args : Array[String] = Array(-silent, -samples, 100, -silent)
object Opts extends Enumeration {
class OptVal extends Val {
override def toString = "-" + super.toString
}
val nopar, silent = new OptVal() { // boolean options
def apply(): Boolean = args.contains(toString)
}
val samples, maxgen = new OptVal() { // integer options
def apply(default: Int) = { val i = args.indexOf(toString) ; if (i == -1) default else args(i+1).toInt}
def apply(): Int = apply(-1)
}
}
Opts.nopar() //> res0: Boolean = false
Opts.silent() //> res1: Boolean = true
Opts.samples() //> res2: Int = 100
Opts.maxgen() //> res3: Int = -1
I understand that solution has two major flaws that may distract you: It eliminates the freedom (i.e. the dependence on other libraries, that you value so much) and redundancy (the DRY principle, you do type the option name only once, as Scala program variable and eliminate it second time typed as command line text).
I have a naive solution but useful. Here is the code:
<Grid Name="TVGrid" Background="#7F000000"> <ScrollBar Background="Black" Orientation="Vertical" Height="35" HorizontalAlignment="Left" Margin="215,254,0,0" Minimum="0" Maximum="10" LargeChange="10" Value="{Binding ElementName=channeltext2, Path=Text}" x:Name="scroll" VerticalAlignment="Top" Width="12" RenderTransformOrigin="0.5,0.5" ValueChanged="scroll_ValueChanged" >
<ScrollBar.RenderTransform>
<TransformGroup>
<ScaleTransform/>
<SkewTransform/>
<RotateTransform Angle="-180"/>
<TranslateTransform/>
</TransformGroup>
</ScrollBar.RenderTransform>
</ScrollBar>
<TextBox Name="channeltext" HorizontalContentAlignment="Center" FontSize="20" Background="Black" Foreground="White" Height="35" HorizontalAlignment="Left" Margin="147,254,0,0" VerticalAlignment="Top" Width="53" Text="0" />
<TextBox Name="channeltext2" Visibility="Hidden" HorizontalContentAlignment="Center" FontSize="20" Background="Black" Foreground="White" Height="35" HorizontalAlignment="Left" Margin="147,254,0,0" VerticalAlignment="Top" Width="53" Text="0" /> </Grid>
I have faced the same situation while designing custom notification. I have tried with the following attribute set with true.
android:layout_centerInParent.
How about programmatically modifying the size attribute on the input?
Semantically (imo), this solution is better than the accepted solution because it still uses input fields for user input but it does introduce a little bit of jQuery. Soundcloud does something similar to this for their tagging.
<input size="1" />
$('input').on('keydown', function(evt) {
var $this = $(this),
size = parseInt($this.attr('size'), 10),
isValidKey = (evt.which >= 65 && evt.which <= 90) || // a-zA-Z
(evt.which >= 48 && evt.which <= 57) || // 0-9
evt.which === 32;
if ( evt.which === 8 && size > 0 ) {
// backspace
$this.attr('size', size - 1);
} else if ( isValidKey ) {
// all other keystrokes
$this.attr('size', size + 1);
}
});
If you know (or if you can "guess") the path to the .apk
(it seems to be of the format /data/app/com.example.someapp-{1,2,..}.apk
to , then you can just copy it from /data/app
as well. This worked even on my non-rooted, stock Android phone.
Just use a Terminal Emulator app (such as this one) and run:
# step 1: confirm path
ls /data/app/com.example.someapp-1.apk
# if it doesn't show up, try -2, -3. Note that globbing (using *) doesn't work here.
# step 2: copy (make sure you adapt the path to match what you discovered above)
cp /data/app/com.example.someapp-1.apk /mnt/sdcard/
Then you can move it from the SD-card to wherever you want (or attach it to an email etc). The last bit might be technically optional, but it makes your life a lot easier when trying to do something with the .apk
file.
You need to know the chunk size by which you're dividing your list. Say you have a list of 108 entries
and you need a chunk size of 25
. Thus you will end up with 5 lists
:
25 entries
each;8 elements
. Code:
public static void main(String[] args) {
List<Integer> list = new ArrayList<Integer>();
for (int i=0; i<108; i++){
list.add(i);
}
int size= list.size();
int j=0;
List< List<Integer> > splittedList = new ArrayList<List<Integer>>() ;
List<Integer> tempList = new ArrayList<Integer>();
for(j=0;j<size;j++){
tempList.add(list.get(j));
if((j+1)%25==0){
// chunk of 25 created and clearing tempList
splittedList.add(tempList);
tempList = null;
//intializing it again for new chunk
tempList = new ArrayList<Integer>();
}
}
if(size%25!=0){
//adding the remaining enteries
splittedList.add(tempList);
}
for (int k=0;k<splittedList.size(); k++){
//(k+1) because we started from k=0
System.out.println("Chunk number: "+(k+1)+" has elements = "+splittedList.get(k).size());
}
}
Bottom line is that you'll have to write a new css rule for that.
Depending on which bundle of Twitter Bootstrap you're using, you should have variables for the various colours.
Try something like:
.table tbody tr > td {
&.success { background-color: $green; }
&.info { background-color: $blue; }
...
}
Surely there's a way to use extend
or the LESS equivalent to avoid repeating the same styling.
if your text has newlines, use nl2br php function:
<?php
$string = "foo"."\n"."bar";
echo nl2br($string);
?>
This should look good in browser
you could use a recursive method like below:
public static String getAllNumbersFromString(String input) {
if (input == null || input.length() == 0) {
return "";
}
char c = input.charAt(input.length() - 1);
String newinput = input.substring(0, input.length() - 1);
if (c >= '0' && c<= '9') {
return getAllNumbersFromString(newinput) + c;
} else {
return getAllNumbersFromString(newinput);
}
}
You are asking a lot of questions that you could answer yourself by reading the documentation, so I'll give you a general advice: read it and experiment in the python shell. You'll see that itemgetter
returns a callable:
>>> func = operator.itemgetter(1)
>>> func(a)
['Paul', 22, 'Car Dealer']
>>> func(a[0])
8
To do it in a different way, you can use lambda
:
a.sort(key=lambda x: x[1])
And reverse it:
a.sort(key=operator.itemgetter(1), reverse=True)
Sort by more than one column:
a.sort(key=operator.itemgetter(1,2))
See the sorting How To.
It is important to notice that in C# the char type is stored as Unicode UTF-16.
char c = (char)88;
or
char c = Convert.ToChar(88)
int asciiCode = (int)'A';
The literal must be ASCII equivalent. For example:
string str = "X?????????";
Console.WriteLine((int)str[0]);
Console.WriteLine((int)str[1]);
will print
X
3626
Extended ASCII ranges from 0 to 255.
Using the Symbol
char c = 'X';
Using the Unicode code
char c = '\u0058';
Using the Hexadecimal
char c = '\x0058';

Bootstrap 4 (^beta) has changed the classes for responsive hiding/showing elements. See this link for correct classes to use: http://getbootstrap.com/docs/4.0/utilities/display/#hiding-elements
This is a common formatting floating number use case.
Unfortunately, all of the built-in one-letter format strings (eg. F, G, N) won't achieve this directly.
For example, num.ToString("F2")
will always show 2 decimal places like 123.40
.
You'll have to use 0.##
pattern even it looks a little verbose.
A complete code example:
double a = 123.4567;
double b = 123.40;
double c = 123.00;
string sa = a.ToString("0.##"); // 123.46
string sb = b.ToString("0.##"); // 123.4
string sc = c.ToString("0.##"); // 123
Perhaps this description helps you in your task.
This operation is a complement, not a negation.
Consider that ~0 = -1, and work from there.
The algorithm for negation is, "complement, increment".
Did you know? There is also "one's complement" where the inverse numbers are symmetrical, and it has both a 0 and a -0.
You can simply define the key to use directly when running the command:
ansible-playbook \
\ # Super verbose output incl. SSH-Details:
-vvvv \
\ # The Server to target: (Keep the trailing comma!)
-i "000.000.0.000," \
\ # Define the key to use:
--private-key=~/.ssh/id_rsa_ansible \
\ # The `env` var is needed if `python` is not available:
-e 'ansible_python_interpreter=/usr/bin/python3' \ # Needed if `python` is not available
\ # Dry–Run:
--check \
deploy.yml
Copy/ Paste:
ansible-playbook -vvvv --private-key=/Users/you/.ssh/your_key deploy.yml
I also had this problem. To sort out the problem of spaces in the middle of the string this line of code always works:
String field = field.replaceAll("\\s+", "");
Automatic bidirectional sorting only works with the SQL data source. Unfortunately, all the documentation in MSDN assumes you are using that, so GridView can get a bit frustrating.
The way I do it is by keeping track of the order on my own. For example:
protected void OnSortingResults(object sender, GridViewSortEventArgs e)
{
// If we're toggling sort on the same column, we simply toggle the direction. Otherwise, ASC it is.
// e.SortDirection is useless and unreliable (only works with SQL data source).
if (_sortBy == e.SortExpression)
_sortDirection = _sortDirection == SortDirection.Descending ? SortDirection.Ascending : SortDirection.Descending;
else
_sortDirection = SortDirection.Ascending;
_sortBy = e.SortExpression;
BindResults();
}
Generally speaking an HTTP POST assumes the content of the body contains a series of key/value pairs that are created (most usually) by a form on the HTML side. You don't set the values using setHeader, as that won't place them in the content body.
So with your second test, the problem that you have here is that your client is not creating multiple key/value pairs, it only created one and that got mapped by default to the first argument in your method.
There are a couple of options you can use. First, you could change your method to accept only one input parameter, and then pass in a JSON string as you do in your second test. Once inside the method, you then parse the JSON string into an object that would allow access to the fields.
Another option is to define a class that represents the fields of the input types and make that the only input parameter. For example
class MyInput
{
String str1;
String str2;
public MyInput() { }
// getters, setters
}
@POST
@Consumes({"application/json"})
@Path("create/")
public void create(MyInput in){
System.out.println("value 1 = " + in.getStr1());
System.out.println("value 2 = " + in.getStr2());
}
Depending on the REST framework you are using it should handle the de-serialization of the JSON for you.
The last option is to construct a POST body that looks like:
str1=value1&str2=value2
then add some additional annotations to your server method:
public void create(@QueryParam("str1") String str1,
@QueryParam("str2") String str2)
@QueryParam doesn't care if the field is in a form post or in the URL (like a GET query).
If you want to continue using individual arguments on the input then the key is generate the client request to provide named query parameters, either in the URL (for a GET) or in the body of the POST.

val refined_df = df.withColumn("rn", row_number.over(w)).where($"rn" === 1).drop("rn")
For a system with legacy usb coming back and libusb-1.0, this approach will work to retrieve the various actual strings. I show the vendor and product as examples. It can cause some I/O, because it actually reads the info from the device (at least the first time, anyway.) Some devices don't provide this information, so the presumption that they do will throw an exception in that case; that's ok, so we pass.
import usb.core
import usb.backend.libusb1
busses = usb.busses()
for bus in busses:
devices = bus.devices
for dev in devices:
if dev != None:
try:
xdev = usb.core.find(idVendor=dev.idVendor, idProduct=dev.idProduct)
if xdev._manufacturer is None:
xdev._manufacturer = usb.util.get_string(xdev, xdev.iManufacturer)
if xdev._product is None:
xdev._product = usb.util.get_string(xdev, xdev.iProduct)
stx = '%6d %6d: '+str(xdev._manufacturer).strip()+' = '+str(xdev._product).strip()
print stx % (dev.idVendor,dev.idProduct)

export PYTHONIOENCODING=utf-8
do the job, but can't set it on python itself ...
what we can do is verify if isn't setting and tell the user to set it before call script with :
if __name__ == '__main__':
if (sys.stdout.encoding is None):
print >> sys.stderr, "please set python env PYTHONIOENCODING=UTF-8, example: export PYTHONIOENCODING=UTF-8, when write to stdout."
exit(1)

python --version
Python 2.7.13

This is how I solved the problem:
@{int proID = 123; int nonProID = 456;}
<script type="text/javascript">
var nonID = Number(@nonProID);
var proID = Number(@proID);
</script>
It is self-documenting and it doesn't involve conversion to and from text.
Note: be careful to use the Number()
function not create new Number()
objects - as the exactly equals operator may behave in a non-obvious way:
var y = new Number(123); // Note incorrect usage of "new"
var x = new Number(123);
alert(y === 123); // displays false
alert(x == y); // displays false
var myElement = $("a[href='http://www.stackoverflow.com']");
SHA1 and a salt should suffice (depending, naturally, on whether you are coding something for Fort Knox or a login system for your shopping list) for the foreseeable future. If SHA1 isn't good enough for you, use SHA256.
The idea of a salt is to throw the hashing results off balance, so to say. It is known, for example, that the MD5-hash of an empty string is d41d8cd98f00b204e9800998ecf8427e
. So, if someone with good enough a memory would see that hash and know that it's the hash of an empty string. But if the string is salted (say, with the string "MY_PERSONAL_SALT
"), the hash for the 'empty string' (i.e. "MY_PERSONAL_SALT
") becomes aeac2612626724592271634fb14d3ea6
, hence non-obvious to backtrace. What I'm trying to say, that it's better to use any salt, than not to. Therefore, it's not too much of an importance to know which salt to use.
There are actually websites that do just this - you can feed it a (md5) hash, and it spits out a known plaintext that generates that particular hash. If you would get access to a database that stores plain md5-hashes, it would be trivial for you to enter the hash for the admin to such a service, and log in. But, if the passwords were salted, such a service would become ineffective.
Also, double-hashing is generally regarded as bad method, because it diminishes the result space. All popular hashes are fixed-length. Thus, you can have only a finite values of this fixed length, and the results become less varied. This could be regarded as another form of salting, but I wouldn't recommend it.
In VB.NET, you need to use the GetType
method to retrieve the type of an instance of an object, and the GetType()
operator to retrieve the type of another known type.
Once you have the two types, you can simply compare them using the Is
operator.
So your code should actually be written like this:
Sub FillCategories(ByVal Obj As Object)
Dim cmd As New SqlCommand("sp_Resources_Categories", Conn)
cmd.CommandType = CommandType.StoredProcedure
Obj.DataSource = cmd.ExecuteReader
If Obj.GetType() Is GetType(System.Web.UI.WebControls.DropDownList) Then
End If
Obj.DataBind()
End Sub
You can also use the TypeOf
operator instead of the GetType
method. Note that this tests if your object is compatible with the given type, not that it is the same type. That would look like this:
If TypeOf Obj Is System.Web.UI.WebControls.DropDownList Then
End If
Totally trivial, irrelevant nitpick: Traditionally, the names of parameters are camelCased (which means they always start with a lower-case letter) when writing .NET code (either VB.NET or C#). This makes them easy to distinguish at a glance from classes, types, methods, etc.
Use the simple way:
<%= Html.RadioButtonFor(m => m.Gender, "Male", new { Checked = "checked" })%>
Code To Get Today's date in any specific Format
You can define the desired format in SimpleDateFormat instance to get the date in that specific formate
DateFormat dateFormat = new SimpleDateFormat("MM/dd/yyyy");
Calendar cal = Calendar.getInstance();
Date date = cal.getTime();
String todaysdate = dateFormat.format(date);
System.out.println("Today's date : " + todaysdate);
Follow below links to see the valid date format combination.
https://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html
CODE : To get x days ahead or Previous from Today's date, To get the past date or Future date.
For Example :
Today date : 11/27/2018
xdayFromTodaysDate = 2 to get date as 11/29/2018
xdayFromTodaysDate = -2 to get date as 11/25/2018
public String getAniversaryDate(int xdayFromTodaysDate ){
DateFormat dateFormat = new SimpleDateFormat("MM/dd/yyyy");
Calendar cal = Calendar.getInstance();
Date date = cal.getTime();
cal.setTime(date);
cal.add(Calendar.DAY_OF_MONTH,xdayFromTodaysDate);
date = cal.getTime();
String aniversaryDate = dateFormat.format(date);
LOGGER.info("Today's date : " + todaysdate);
return aniversaryDate;
}
CODE : To get x days ahead or Previous from a Given date
public String getAniversaryDate(String givendate, int xdayFromTodaysDate ){
Calendar cal = Calendar.getInstance();
DateFormat dateFormat = new SimpleDateFormat("MM/dd/yyyy");
try {
Date date = dateFormat.parse(givendate);
cal.setTime(date);
cal.add(Calendar.DAY_OF_MONTH,xdayFromTodaysDate);
date = cal.getTime();
String aniversaryDate = dateFormat.format(date);
LOGGER.info("aniversaryDate : " + aniversaryDate);
return aniversaryDate;
} catch (ParseException e) {
e.printStackTrace();
return null;
}
}
Looks file you use the .mkdirs()
method on a File
object: http://www.roseindia.net/java/beginners/java-create-directory.shtml
// Create a directory; all non-existent ancestor directories are
// automatically created
success = (new File("../potentially/long/pathname/without/all/dirs")).mkdirs();
if (!success) {
// Directory creation failed
}
Have a look at the white-space
property, used like this:
th {
white-space: nowrap;
}
This will force the contents of <th>
to display on one line.
From linked page, here are the various options for white-space
:
normal
This value directs user agents to collapse sequences of white space, and break lines as necessary to fill line boxes.pre
This value prevents user agents from collapsing sequences of white space. Lines are only broken at preserved newline characters.nowrap
This value collapses white space as for 'normal', but suppresses line breaks within text.pre-wrap
This value prevents user agents from collapsing sequences of white space. Lines are broken at preserved newline characters, and as necessary to fill line boxes.pre-line
This value directs user agents to collapse sequences of white space. Lines are broken at preserved newline characters, and as necessary to fill line boxes.
To have a consistent flow of the images on different devices, you'd have to specify the width and height value for each carousel image item, for instance here in my example the image would take the full width but with a height of "400px" (you can specify your personal value instead)
<div class="item">
<img src="image.jpg" style="width:100%; height: 400px;">
</div>
I've personally always stuck to max width of 1000px, centered in the middle of the page (via margin left/right: auto).
If you're running at anything less than 1024x768, it's time to upgrade. Seriously. It's almost 2010. You can buy bargain bin lcd monitors with a native res of 1280x1024.
I create this extension if you want
extension UILabel {
func setSizeFont (sizeFont: CGFloat) {
self.font = UIFont(name: self.font.fontName, size: sizeFont)!
self.sizeToFit()
}
}
You can also plot to a png file using gnuplot (which is free):
terminal commands
gnuplot> set title '<title>'
gnuplot> set ylabel '<yLabel>'
gnuplot> set xlabel '<xLabel>'
gnuplot> set grid
gnuplot> set term png
gnuplot> set output '<Output file name>.png'
gnuplot> plot '<fromfile.csv>'
note: you always need to give the right extension (.png here) at set output
Then it is also possible that the ouput is not lines, because your data is not continues. To fix this simply change the 'plot' line to:
plot '<Fromfile.csv>' with line lt -1 lw 2
More line editing options (dashes and line color ect.) at: http://gnuplot.sourceforge.net/demo_canvas/dashcolor.html
apt-get install gnuplot
)brew install gnuplot
)A 'button' is just that, a button, to which you can add additional functionality using Javascript. A 'submit' input type has the default functionality of submitting the form it's placed in (though, of course, you can still add additional functionality using Javascript).
If you want to set the image as the background, I've got a solution:
.image {
background-image: url(yourimage.jpg);
background-position: center;
}
<ul>
<li ng-repeat=interface in interfaces>
<img src='green-checkmark.png' ng-show="interface=='UP'" />
<img src='big-black-X.png' ng-show="interface=='DOWN'" />
</li>
</ul>
A nice solution without using interop:
As always, simply enable DoubleBuffered=true on your CustomControl. Then, if you have any containers like FlowLayoutPanel or TableLayoutPanel, derive a class from each of these types and in the constructors, enable double buffering. Now, simply use your derived Containers instead of the Windows.Forms Containers.
class TableLayoutPanel : System.Windows.Forms.TableLayoutPanel
{
public TableLayoutPanel()
{
DoubleBuffered = true;
}
}
class FlowLayoutPanel : System.Windows.Forms.FlowLayoutPanel
{
public FlowLayoutPanel()
{
DoubleBuffered = true;
}
}
I don't know what language you're using, but .NET has the environment variable PROCESSOR_ARCHITEW6432
if the OS is 64-bit.
If all you want to know is whether your application is running 32-bit or 64-bit, you can check IntPtr.Size
. It will be 4 if running in 32-bit mode and 8 if running in 64-bit mode.
(ps - I couldn't comment) I think your best bet is something like you've done, or similar to:
$user = User::where('mobile', Input::get('mobile'));
$user->exists() and $user = $user->first();
Oh, also: count()
instead if exists
but this could be something used after get
.
SELECT * FROM all_procedures WHERE OBJECT_TYPE IN ('FUNCTION','PROCEDURE','PACKAGE')
and owner = 'Schema_name' order by object_name
here 'Schema_name' is a name of schema, example i have a schema named PMIS, so the example will be
SELECT * FROM all_procedures WHERE OBJECT_TYPE IN ('FUNCTION','PROCEDURE','PACKAGE')
and owner = 'PMIS' order by object_name
Ref: https://www.plsql.co/list-all-procedures-from-a-schema-of-oracle-database.html
You can do something like this:
$('.notice')
.fadeIn()
.animate({opacity: '+=0'}, 2000) // Does nothing for 2000ms
.fadeOut('fast');
Sadly, you can't just do .animate({}, 2000) -- I think this is a bug, and will report it.
In case the given answers still don't help you remove that, try this:
Manually delete the line in require
from composer.json
Run composer update
You have a misplaced closing brace before the return
statement.
Or you could do it the evil way.
var a = [1,2,3,4,5,6,7,8,9];
sum = eval(a.join("+"));
;)
Maybe the string
keyword confused you, as it looks exactly like any other value type declaration, but it is actually an alias to System.String
as explained in this question.
Also the dark blue color in Visual Studio and the lowercase first letter may mislead into thinking it is a struct
.
You need to use an Angular form directive on the select
. You can do that with ngModel
. For example
@Component({
selector: 'my-app',
template: `
<h2>Select demo</h2>
<select [(ngModel)]="selectedCity" (ngModelChange)="onChange($event)" >
<option *ngFor="let c of cities" [ngValue]="c"> {{c.name}} </option>
</select>
`
})
class App {
cities = [{'name': 'SF'}, {'name': 'NYC'}, {'name': 'Buffalo'}];
selectedCity = this.cities[1];
onChange(city) {
alert(city.name);
}
}
The (ngModelChange)
event listener emits events when the selected value changes. This is where you can hookup your callback.
Note you will need to make sure you have imported the FormsModule
into the application.
Here is a Plunker
I think above examples are correct. but you dont' really need to set
request.setAttribute("selectedDept", selectedDept);
you can reuse that info from JSTL, just do something like this..
<!DOCTYPE html>
<html lang="en">
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>
<head>
<script src="../js/jquery-1.8.1.min.js"></script>
</head>
<body>
<c:set var="authors" value="aaa,bbb,ccc,ddd,eee,fff,ggg" scope="application" />
<c:out value="Before : ${param.Author}"/>
<form action="TestSelect.action">
<label>Author
<select id="Author" name="Author">
<c:forEach items="${fn:split(authors, ',')}" var="author">
<option value="${author}" ${author == param.Author ? 'selected' : ''}>${author}</option>
</c:forEach>
</select>
</label>
<button type="submit" value="submit" name="Submit"></button>
<Br>
<c:out value="After : ${param.Author}"/>
</form>
</body>
</html>
Simplified version:
Date.prototype.clone = function () {
return new Date(this.getTime());
}
In case you want to checkif the string matches the whole line and if it is a fixed string, You can do it this way
grep -Fxq [String] [filePath]
example
searchString="Hello World"
file="./test.log"
if grep -Fxq "$searchString" $file
then
echo "String found in $file"
else
echo "String not found in $file"
fi
From the man file:
-F, --fixed-strings
Interpret PATTERN as a list of fixed strings, separated by newlines, any of
which is to be matched.
(-F is specified by POSIX.)
-x, --line-regexp
Select only those matches that exactly match the whole line. (-x is specified by
POSIX.)
-q, --quiet, --silent
Quiet; do not write anything to standard output. Exit immediately with zero
status if any match is
found, even if an error was detected. Also see the -s or --no-messages
option. (-q is specified by
POSIX.)
When you do not know the exact length of non-nil bytes in the array, you can trim it first:
string(bytes.Trim(arr, "\x00"))
You didn't provide many details, but you could try something like this:
# conn is an ODBC connection to the DB
dbCursor = conn.cursor()
sql = ('select field1, field2 from table')
dbCursor = conn.cursor()
dbCursor.execute(sql)
for row in dbCursor:
# Now you should be able to access the fields as properties of "row"
myVar1 = row.field1
myVar2 = row.field2
conn.close()
The answer was surprisingly simple. I had to add a Content-Type
header in the POST
request with a value of application/json
. Without this header Jersey did not know what to do with the request body (in spite of the @Consumes(MediaType.APPLICATION_JSON)
annotation)!
In case of adding new rows for array in loop, Assign the array directly for firsttime in loop instead of initialising an empty array.
for i in range(0,len(0,100)):
SOMECALCULATEDARRAY = .......
if(i==0):
finalArrayCollection = SOMECALCULATEDARRAY
else:
finalArrayCollection = np.vstack(finalArrayCollection,SOMECALCULATEDARRAY)
This is mainly useful when the shape of the array is unknown
The "protected internal" access modifier is a union of both the "protected" and "internal" modifiers.
From MSDN, Access Modifiers (C# Programming Guide):
The type or member can be accessed only by code in the same class or struct, or in a class that is derived from that class.
The type or member can be accessed by any code in the same assembly, but not from another assembly.
protected internal:
The type or member can be accessed by any code in the assembly in which it is declared, OR from within a derived class in another assembly. Access from another assembly must take place within a class declaration that derives from the class in which the protected internal element is declared, and it must take place through an instance of the derived class type.
Note that: protected internal
means "protected
OR internal
" (any class in the same assembly, or any derived class - even if it is in a different assembly).
...and for completeness:
The type or member can be accessed only by code in the same class or struct.
The type or member can be accessed by any other code in the same assembly or another assembly that references it.
Access is limited to the containing class or types derived from the containing class within the current assembly.
(Available since C# 7.2)

Tested and worked in IE, Firefox, Chrome, Safari and Opera. I did not test IE6. The outer text-align is needed for IE. Other browsers (and IE9?) will work when you give the DIV margin (left and right) value of auto. Margin "0 auto" is a shorthand for margin "0 auto 0 auto" (top right bottom left).
Note: the text is also centered inside the inner DIV, if you want it to remain on the left side just specify text-align: left; for the inner DIV.
Edit: IE 6, 7, 8 and 9 running on the Standards Mode will work with margins set to auto.
Good that you've managed to get it working with the html5 mode but it is also possible to make it work in the hashbang mode.
You could simply use:
$location.search().target
to get access to the 'target' search param.

I'll Explain how to add an image using Android studio(2.3.3). First you need to add the image into res/drawable folder in the project. Like below
Now in go to activity_main.xml (or any activity you need to add image) and select the Design view. There you can see your Palette tool box on left side. You need to drag and drop ImageView.
It will prompt you Resources dialog box. In there select Drawable under the project section you can see your image. Like below
Select the image you want press Ok you can see the image on the Design view. If you want it configure using xml it would look like below.
<ImageView
android:id="@+id/imageView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:srcCompat="@drawable/homepage"
tools:layout_editor_absoluteX="55dp"
tools:layout_editor_absoluteY="130dp" />
You need to give image location using
app:srcCompat="@drawable/imagename"
Use the STL
#include <iostream>
#include <vector>
#include <algorithm>
#include <iterator>
int main()
{
std::vector<int> userInput;
// Read until end of input.
// Hit control D
std::copy(std::istream_iterator<int>(std::cin),
std::istream_iterator<int>(),
std::back_inserter(userInput)
);
// Print in Normal order
std::copy(userInput.begin(),
userInput.end(),
std::ostream_iterator<int>(std::cout,",")
);
std::cout << "\n";
// Print in reverse order:
std::copy(userInput.rbegin(),
userInput.rend(),
std::ostream_iterator<int>(std::cout,",")
);
std::cout << "\n";
// Update for C++11
// Range based for is now a good alternative.
for(auto const& value: userInput)
{
std::cout << value << ",";
}
std::cout << "\n";
}
This is my code. Not perfect, but working good. I hope it helps somebody:
static System.Data.DataTable DtTbl (System.Data.DataTable[] dtToJoin)
{
System.Data.DataTable dtJoined = new System.Data.DataTable();
foreach (System.Data.DataColumn dc in dtToJoin[0].Columns)
dtJoined.Columns.Add(dc.ColumnName);
foreach (System.Data.DataTable dt in dtToJoin)
foreach (System.Data.DataRow dr1 in dt.Rows)
{
System.Data.DataRow dr = dtJoined.NewRow();
foreach (System.Data.DataColumn dc in dtToJoin[0].Columns)
dr[dc.ColumnName] = dr1[dc.ColumnName];
dtJoined.Rows.Add(dr);
}
return dtJoined;
}
try this:
sed "s/Suzi/$secondString/g" <<<"$firstString"
had the same problem in windows, the reason is always displayed at the top of the window(where you browse for the location)
I wanted to be able to access my application with the HTML5 mode and a fixed token and then switch to the hashbang method (to keep the token so the user can refresh his page).
URL for accessing my app:
http://myapp.com/amazing_url?token=super_token
Then when the user loads the page:
http://myapp.com/amazing_url?token=super_token#/amazing_url
Then when the user navigates:
http://myapp.com/amazing_url?token=super_token#/another_url
With this I keep the token in the URL and keep the state when the user is browsing. I lost a bit of visibility of the URL, but there is no perfect way of doing it.
So don't enable the HTML5 mode and then add this controller:
.config ($stateProvider)->
$stateProvider.state('home-loading', {
url: '/',
controller: 'homeController'
})
.controller 'homeController', ($state, $location)->
if window.location.pathname != '/'
$location.url(window.location.pathname+window.location.search).replace()
else
$state.go('home', {}, { location: 'replace' })

I used the CSS in the accepted answer here for my responsive YouTube videos - worked great right up until YouTube updated their system around the start of August 2015. The videos on YouTube are the same dimensions but for whatever reason the CSS in the accepted answer now letterboxes all our videos. Black bands across top and bottom.
I've tickered around with the sizes and settled on getting rid of the top padding and changing the bottom padding to 56.45%
. Seems to look good.
.videowrapper {
position: relative;
padding-bottom: 56.45%;
height: 0;
}
When you want to change the encoding you always go from one into another. So you might go from Mac Roman
to UTF-8
or from ASCII
to UTF-8
.
It's as important to know the desired output encoding as the current source encoding. For example if you have Mac Roman
and you decode it from UTF-16
to UTF-8
you'll just make it garbled.
If you want to know more about encoding this article goes into a lot of details:
The npm pacakge encoding which uses node-iconv or iconv-lite should allow you to easily specify which source and output encoding you want:
var resultBuffer = encoding.convert(nameString, 'ASCII', 'UTF-8');
It could be that you have not configured the Amazon Security Group assigned to your EC2 Instance to accept incoming requests on port 3306 (default port for MySQL).
If this is the case then you can easily open up the port for the security group in a few button clicks:
1) Log into you AWS Console and go to 'EC2'
2) On the left hand menu under 'Network & Security' go to 'Security Groups'
3) Check the Security Group in question
4) Click on 'Inbound tab'
5) Choose 'MYSQL' from drop down list and click 'Add Rule'
Might not be the reason but worth a go...

You can't get the body of the response from the return value of http.get()
.
http.get()
doesn't return a response object. It returns the request object (http.clientRequest
). So, there isn't any way to get the body of the response from the return value of http.get()
.
I know it's an old question, but reading the documentation you linked to shows that this was the case even when you posted it.
Much easier aproach. Consider a task:
provision:
ansible-playbook -vvvv \
-i .vagrant/provisioners/ansible/inventory/vagrant_ansible_inventory \
--private-key=.vagrant/machines/default/virtualbox/private_key \
--start-at-task="$(AT)" \
-u vagrant playbook.yml
Now when I want to call it I just run something like:
AT="build assets" make provision
or just:
make provision
in this case AT
is an empty string
plot(t)
is in this case the same as
plot(t[[1]], t[[2]])
As the error message says, x and y differ in length and that is because you plot a list with length 4 against 1
:
> length(t)
[1] 4
> length(1)
[1] 1
In your second example you plot a list with elements named x
and y
, both vectors of length 2,
so plot
plots these two vectors.
Edit:
If you want to plot lines use
plot(t, type="l")
Use alter session set current_schema = <username>
, in your case as an execute immediate.
See Oracle's documentation for further information.
In your case, that would probably boil down to (untested)
DECLARE
CURSOR client_cur IS
SELECT distinct username
from all_users
where length(username) = 3;
-- client cursor
CURSOR emails_cur IS
SELECT id, name
FROM org;
BEGIN
FOR client IN client_cur LOOP
-- ****
execute immediate
'alter session set current_schema = ' || client.username;
-- ****
FOR email_rec in client_cur LOOP
dbms_output.put_line(
'Org id is ' || email_rec.id ||
' org nam ' || email_rec.name);
END LOOP;
END LOOP;
END;

You should watch session 147 from the WWDC 2010 Session videos. It is "Advanced Performance Optimization on iPhone OS, part 2".
There is a lot of good advice on memory optimizations.
Some of the tips are:
NSAutoReleasePool
s to make sure your memory usage does not spike.CGImageSource
when creating thumbnails from large images.The default value for a GUID is empty. (eg: 00000000-0000-0000-0000-000000000000)
This can be invoked using Guid.Empty
or new Guid()
If you want a new GUID, you use Guid.NewGuid()

Store their UserId and a RememberMeToken. When they login with remember me checked generate a new RememberMeToken (which invalidate any other machines which are marked are remember me).
When they return look them up by the remember me token and make sure the UserId matches.
git reset --hard origin/master
says: throw away all my staged and unstaged changes, forget everything on my current local branch and make it exactly the same as origin/master
.
You probably wanted to ask this before you ran the command. The destructive nature is hinted at by using the same words as in "hard reset".
We can also try this solution
ApplicationContext ctx = new ClassPathXmlApplicationContext("classpath*:app-context.xml");
in this the spring automatically finds the class in the class path itself
Let's say you're opening the file with a with
statement like you should be. Then you'd do something like this to read from your file:
with open('somefile.txt', 'w+') as f:
# Note that f has now been truncated to 0 bytes, so you'll only
# be able to read data that you write after this point
f.write('somedata\n')
f.seek(0) # Important: return to the top of the file before reading, otherwise you'll just read an empty string
data = f.read() # Returns 'somedata\n'
Note the f.seek(0)
-- if you forget this, the f.read()
call will try to read from the end of the file, and will return an empty string.
The best way is to simply use Convert.ToInt32
. It is fast and also rounds correctly.
Why make it more complicated?
git reset HEAD~1
if you don't want your changes to be gone(unstaged changes). Change, commit and push again git push -f [origin] [branch]
To connect from the localhost you need to add '--net host':
docker run --name some-postgres --net host -e POSTGRES_PASSWORD=mysecretpassword -d -p 5432:5432 postgres
You can access the server directly without using exec from your localhost, by using:
psql -h localhost -p 5432 -U postgres
There are probably embedded tabs (CHAR(9)
) etc. as well. You can find out what other characters you need to replace (we have no idea what your goal is) with something like this:
DECLARE @var NVARCHAR(255), @i INT;
SET @i = 1;
SELECT @var = AccountType FROM dbo.Account
WHERE AccountNumber = 200
AND AccountType LIKE '%Daily%';
CREATE TABLE #x(i INT PRIMARY KEY, c NCHAR(1), a NCHAR(1));
WHILE @i <= LEN(@var)
BEGIN
INSERT #x
SELECT SUBSTRING(@var, @i, 1), ASCII(SUBSTRING(@var, @i, 1));
SET @i = @i + 1;
END
SELECT i,c,a FROM #x ORDER BY i;
You might also consider doing better cleansing of this data before it gets into your database. Cleaning it every time you need to search or display is not the best approach.
USING JAVA 8:
Map<String, String> headerMap = Arrays.stream(header.split(","))
.map(s -> s.split(":"))
.collect(Collectors.toMap(s -> s[0], s -> s[1]));
I'd use minlog, personally. It's extremely simple, as the logging class is a few hundred lines of code.
simple one:
[[@"first" stringByAppendingString:@"second"] stringByAppendingString:@"third"];
if you have many STRINGS to Concatenate, you should use NSMutableString
for better performance
For those who prefer a minimal working example, meditate on this interactive Python session:
>>> def f():
... yield 1
... yield 2
... yield 3
...
>>> g = f()
>>> for i in g:
... print(i)
...
1
2
3
>>> for i in g:
... print(i)
...
>>> # Note that this time nothing was printed
Its a very old question but I think it will help newbies line me who are learning python. If you have Python 3.4 or above, the pathlib library comes with the default distribution.
To use it, you just pass a path or filename into a new Path() object using forward slashes and it handles the rest. To indicate that the path is a raw string, put r
in front of the string with your actual path.
For example,
from pathlib import Path
dataFolder = Path(r'D:\Desktop dump\example.txt')

For anyone that simply are looking to bypass the ERROR page to display the content on shared hosting. You might wanna try and use redirect in .htaccess file. If it is say 406 error, on UnoEuro it didn't seem to work simply deactivating the security. So I used this instead:
ErrorDocument 406 /
Then you can always change the error status using PHP. But be aware that in my case doing so means I am opening a door to SQL injections as I am bypassing WAF. So you will need to make sure that you either have your own security measures or enable the security again asap.
This way work for me:
@Override
protected void onCreate(Bundle savedInstanceState) {
setTheme(GApplication.getInstance().getTheme());
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
Then you want to change a new theme:
GApplication.getInstance().setTheme(R.style.LightTheme);
recreate();
The Bootstrap team seems to have removed it. See here: https://github.com/twbs/bootstrap/issues/8922 . @Skelly's answer involves custom css which I didn't want to do so I used the grid system and nav-pills. It worked fine and looked great. The code looks like so:
<div class="row">
<!-- Navigation Buttons -->
<div class="col-md-3">
<ul class="nav nav-pills nav-stacked" id="myTabs">
<li class="active"><a href="#home" data-toggle="pill">Home</a></li>
<li><a href="#profile" data-toggle="pill">Profile</a></li>
<li><a href="#messages" data-toggle="pill">Messages</a></li>
</ul>
</div>
<!-- Content -->
<div class="col-md-9">
<div class="tab-content">
<div class="tab-pane active" id="home">Home</div>
<div class="tab-pane" id="profile">Profile</div>
<div class="tab-pane" id="messages">Messages</div>
</div>
</div>
</div>
You can see this in action here: http://bootply.com/81948
[Update]
@SeanK gives the option of not having to enable the nav-pills through Javascript and instead using data-toggle="pill"
. Check it out here: http://bootply.com/96067. Thanks Sean.
You can just use numpy arrays. Look at the numpy for matlab users page for a detailed overview of the pros and cons of arrays w.r.t. matrices.
As I mentioned in the comment, having to use the dot()
function or method for mutiplication of vectors is the biggest pitfall. But then again, numpy arrays are consistent. All operations are element-wise. So adding or subtracting arrays and multiplication with a scalar all work as expected of vectors.
Edit2: Starting with Python 3.5 and numpy 1.10 you can use the @
infix-operator for matrix multiplication, thanks to pep 465.
Edit: Regarding your comment:
Yes. The whole of numpy is based on arrays.
Yes. linalg.norm(v)
is a good way to get the length of a vector. But what you get depends on the possible second argument to norm! Read the docs.
To normalize a vector, just divide it by the length you calculated in (2). Division of arrays by a scalar is also element-wise.
An example in ipython:
In [1]: import math
In [2]: import numpy as np
In [3]: a = np.array([4,2,7])
In [4]: np.linalg.norm(a)
Out[4]: 8.3066238629180749
In [5]: math.sqrt(sum([n**2 for n in a]))
Out[5]: 8.306623862918075
In [6]: b = a/np.linalg.norm(a)
In [7]: np.linalg.norm(b)
Out[7]: 1.0
Note that In [5]
is an alternative way to calculate the length. In [6]
shows normalizing the vector.
task :build => [:some_other_tasks] do
build
end
task :build_all do
[:debug, :release].each { |t| build t }
end
def build(type = :debug)
# ...
end
rake
's idioms, here are your possibilities, compiled from past answers:This always executes the task, but it doesn't execute its dependencies:
Rake::Task["build"].execute
This one executes the dependencies, but it only executes the task if it has not already been invoked:
Rake::Task["build"].invoke
This first resets the task's already_invoked state, allowing the task to then be executed again, dependencies and all:
Rake::Task["build"].reenable
Rake::Task["build"].invoke
Note that dependencies already invoked are not automatically re-executed unless they are re-enabled. In Rake >= 10.3.2, you can use the following to re-enable those as well:
Rake::Task["build"].all_prerequisite_tasks.each(&:reenable)
I had the same problem. This is related to hibernate. I changed the database from dev to production in hibernate.cfg.xml but there were catalog attribute in other hbm.xml files with the old database name and it was causing the issue.
Instead of telling incorrect database name, it showed Permission denied error.
So make sure to change the database name everywhere or just remove the catalog attribute
You can use android:largeHeap="true" to request a larger heap size, but this will not work on any pre Honeycomb devices. On pre 2.3 devices, you can use the VMRuntime class, but this will not work on Gingerbread and above.
The only way to have as large a limit as possible is to do memory intensive tasks via the NDK, as the NDK does not impose memory limits like the SDK.
Alternatively, you could only load the part of the model that is currently in view, and load the rest as you need it, while removing the unused parts from memory. However, this may not be possible, depending on your app.
matching empty string or email

matching empty string or email but also matching any amount of whitespace
(^\s*$|^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.(?:[a-zA-Z]{2}|com|org|net|edu|gov|mil|biz|info|mobi|name|aero|asia|jobs|museum)$)
see more about the email matching regex itself:
That's perfectly fine and will work. But to use sessions you have to put session_start();
on the first line of the php code. So basically
<?php
session_start();
//rest of stuff
?>
You should consider SQL authentication account for database ownership; then you don't have to worry about accounts coming and going, databases or instances moving to different servers, and your next PC name change. I have several systems where we use:
ALTER AUTHORIZATION ON DATABASE::Ariha TO [sa];
Or if you want to change the owner to that local Administrator account, then it should be:
ALTER AUTHORIZATION ON DATABASE::Ariha TO [DevPC\Administrator];
Because renaming the machine to DevPC
has eliminated the local account that used to be named WIN-ND...\Administrator
and this has also invalidated the current owner of the database.
If SELECT @@SERVERNAME;
is not accurate (it should say DevPC
), then in order to ensure that your server rename has taken hold within SQL Server, you may also want to issue the following:
EXEC sys.sp_dropserver @server = N'old server name';
GO
EXEC sys.sp_addserver @server = N'DevPC', @local = N'local';
GO
Try this...

A very simple solution is using the sfcookies package. You just have to install it using npm for example: npm install sfcookies --save
Then you import on the file:
import { bake_cookie, read_cookie, delete_cookie } from 'sfcookies';
create a cookie key:
const cookie_key = 'namedOFCookie';
on your submit function, you create the cookie by saving data on it just like this:
bake_cookie(cookie_key, 'test');
to delete it just do
delete_cookie(cookie_key);
and to read it:
read_cookie(cookie_key)
Simple and easy to use.
Another important difference is that Hashtable
is thread safe. Hashtable
has built in multiple reader/single writer (MR/SW) thread safety which means Hashtable
allows ONE writer together with multiple readers without locking. In the case of Dictionary
there is no thread safety, if you need thread safety you must implement your own synchronization.
To elaborate further:
Hashtable
, provide some thread-safety through the Synchronized property, which returns a thread-safe wrapper around the collection. The wrapper works by locking the entire collection on every add or remove operation. Therefore, each thread that is attempting to access the collection must wait for its turn to take the one lock. This is not scalable and can cause significant performance degradation for large collections. Also, the design is not completely protected from race conditions.The .NET Framework 2.0 collection classes like
List<T>
,Dictionary<TKey, TValue>
, etc do not provide any thread synchronization; user code must provide all synchronization when items are added or removed on multiple threads concurrently If you need type safety as well thread safety, use concurrent collections classes in the .NET Framework. Further reading here.
If you are using rest template, you can use this piece of code
fun getClientHttpRequestFactory(): ClientHttpRequestFactory {
val timeout = envTimeout.toInt()
val config = RequestConfig.custom()
.setConnectTimeout(timeout)
.setConnectionRequestTimeout(timeout)
.setSocketTimeout(timeout)
.build()
val acceptingTrustStrategy = TrustStrategy { chain: Array<X509Certificate?>?, authType: String? -> true }
val sslContext: SSLContext = SSLContexts.custom()
.loadTrustMaterial(null, acceptingTrustStrategy)
.build()
val csf = SSLConnectionSocketFactory(sslContext)
val client = HttpClientBuilder
.create()
.setDefaultRequestConfig(config)
.setSSLSocketFactory(csf)
.setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE)
.build()
return HttpComponentsClientHttpRequestFactory(client)
}
@Bean
fun getRestTemplate(): RestTemplate {
return RestTemplate(getClientHttpRequestFactory())
}
This is my working solution
View view = new View(getApplicationContext());
view.setBackgroundResource(R.color.background);
myEditText.setBackground(view.getBackground());
I just deleted my ~/.m2/repository and that forced a re-download ;)
For your purpose you can use this snnippet:
import org.apache.commons.lang3.StringUtils;
StringUtils.normalizeSpace(string);
This will normalize the spacing to single and will strip off the starting and trailing whitespaces as well.
String sampleString = "Hello world!";
sampleString.replaceAll("\\s{2}", " "); // replaces exactly two consecutive spaces
sampleString.replaceAll("\\s{2,}", " "); // replaces two or more consecutive white spaces
You could use OHHTTPStubs and stub the network requests to specific URLs to fail.
As toolkit mentions above, Apache Commons IO is the way to go, specifically FileUtils.copyFile(); it handles all the heavy lifting for you.
And as a postscript, note that recent versions of FileUtils (such as the 2.0.1 release) have added the use of NIO for copying files; NIO can significantly increase file-copying performance, in a large part because the NIO routines defer copying directly to the OS/filesystem rather than handle it by reading and writing bytes through the Java layer. So if you're looking for performance, it might be worth checking that you are using a recent version of FileUtils.
I think this could help - CASE the columns value to NULL if it's duplicate - then it's not appended to LISTAGG string:
with test_data as
(
select 1 as col1, 2 as col2, 'Smith' as created_by from dual
union select 1, 2, 'John' from dual
union select 1, 3, 'Ajay' from dual
union select 1, 4, 'Ram' from dual
union select 1, 5, 'Jack' from dual
union select 2, 5, 'Smith' from dual
union select 2, 6, 'John' from dual
union select 2, 6, 'Ajay' from dual
union select 2, 6, 'Ram' from dual
union select 2, 7, 'Jack' from dual
)
SELECT col1 ,
listagg(col2 , ',') within group (order by col2 ASC) AS orig_value,
listagg(CASE WHEN rwn=1 THEN col2 END , ',') within group (order by col2 ASC) AS distinct_value
from
(
select row_number() over (partition by col1,col2 order by 1) as rwn,
a.*
from test_data a
) a
GROUP BY col1
Results in:
COL1 ORIG DISTINCT
1 2,2,3,4,5 2,3,4,5
2 5,6,6,6,7 5,6,7
First, here's some sample data:
set.seed(1)
dat <- data.frame(one = rnorm(15),
two = sample(LETTERS, 15),
three = rnorm(15),
four = runif(15))
dat <- data.frame(lapply(dat, function(x) { x[sample(15, 5)] <- NA; x }))
head(dat)
# one two three four
# 1 NA M 0.80418951 0.8921983
# 2 0.1836433 O -0.05710677 NA
# 3 -0.8356286 L 0.50360797 0.3899895
# 4 NA E NA NA
# 5 0.3295078 S NA 0.9606180
# 6 -0.8204684 <NA> -1.28459935 0.4346595
Here's our replacement:
dat[["four"]][is.na(dat[["four"]])] <- 0
head(dat)
# one two three four
# 1 NA M 0.80418951 0.8921983
# 2 0.1836433 O -0.05710677 0.0000000
# 3 -0.8356286 L 0.50360797 0.3899895
# 4 NA E NA 0.0000000
# 5 0.3295078 S NA 0.9606180
# 6 -0.8204684 <NA> -1.28459935 0.4346595
Alternatively, you can, of course, write dat$four[is.na(dat$four)] <- 0
Or if you use the six library
from six.moves import reduce
Set MaintainScrollPositionOnPostBack="true"
in the page declaration:
<%@ Page Language="C#" MaintainScrollPositionOnPostBack="true" Title="Home" %>
My solution to this problem was to use the $() sub-expression block.
Add-Type -Language CSharp @"
public class Thing{
public string Name;
}
"@;
$x = New-Object Thing
$x.Name = "Bill"
Write-Output "My name is $($x.Name)"
Write-Output "This won't work right: $x.Name"
Gives:
My name is Bill
This won't work right: Thing.Name

In New Xampp
All you have to do is to edit the file:
C:\xampp\apache\conf\extra\httpd-xampp.conf
and go to Directory tag as below:
<Directory "C:/xampp/phpMyAdmin">
and then change
Require local
To
Require all granted
in the Directory tag.
Restart the Xampp. That's it!
If you want all packages in that repository, use ...

Add bluetooth permission to your AndroidManifest,
<uses-permission android:name="android.permission.BLUETOOTH" />
Then use intent filters to listen to the ACTION_ACL_CONNECTED
, ACTION_ACL_DISCONNECT_REQUESTED
, and ACTION_ACL_DISCONNECTED
broadcasts:
public void onCreate() {
...
IntentFilter filter = new IntentFilter();
filter.addAction(BluetoothDevice.ACTION_ACL_CONNECTED);
filter.addAction(BluetoothDevice.ACTION_ACL_DISCONNECT_REQUESTED);
filter.addAction(BluetoothDevice.ACTION_ACL_DISCONNECTED);
this.registerReceiver(mReceiver, filter);
}
//The BroadcastReceiver that listens for bluetooth broadcasts
private final BroadcastReceiver mReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
if (BluetoothDevice.ACTION_FOUND.equals(action)) {
... //Device found
}
else if (BluetoothDevice.ACTION_ACL_CONNECTED.equals(action)) {
... //Device is now connected
}
else if (BluetoothAdapter.ACTION_DISCOVERY_FINISHED.equals(action)) {
... //Done searching
}
else if (BluetoothDevice.ACTION_ACL_DISCONNECT_REQUESTED.equals(action)) {
... //Device is about to disconnect
}
else if (BluetoothDevice.ACTION_ACL_DISCONNECTED.equals(action)) {
... //Device has disconnected
}
}
};
A few notes:
Here is the example in which you can easily find the way to use Post,GET method and use the same way to add other curd operations as well..

To update a subset of fields, you can use update_fields
:
survey.save(update_fields=["active"])
The update_fields
argument was added in Django 1.5. In earlier versions, you could use the update()
method instead:
Survey.objects.filter(pk=survey.pk).update(active=True)
If you need to get current position in form's area(got experimentally), try:
Console.WriteLine("Current mouse position in form's area is " +
(Control.MousePosition.X - this.Location.X - 8).ToString() +
"x" +
(Control.MousePosition.Y - this.Location.Y - 30).ToString()
);
Although, 8 and 30 integers were found by experimenting.
Would be awesome if someone could explain why exactly these numbers ^.
Also, there's another variant(considering code is in Form's CodeBehind):
Point cp = PointToClient(Cursor.Position); // Getting a cursor's position according form's area
Console.WriteLine("Cursor position: X = " + cp.X + ", Y = " + cp.Y);
Based on some comments above below is the code how to remove an object based on a key name and key value
var items = [
{ "id": 3.1, "name": "test 3.1"},
{ "id": 22, "name": "test 3.1" },
{ "id": 23, "name": "changed test 23" }
]
function removeByKey(array, params){
array.some(function(item, index) {
return (array[index][params.key] === params.value) ? !!(array.splice(index, 1)) : false;
});
return array;
}
var removed = removeByKey(items, {
key: 'id',
value: 23
});
console.log(removed);
When the directory is deleted, the inode for that directory (and the inodes for its contents) are recycled. The pointer your shell has to that directory's inode (and its contents's inodes) are now no longer valid. When the directory is restored from backup, the old inodes are not (necessarily) reused; the directory and its contents are stored on random inodes. The only thing that stays the same is that the parent directory reuses the same name for the restored directory (because you told it to).
Now if you attempt to access the contents of the directory that your original shell is still pointing to, it communicates that request to the file system as a request for the original inode, which has since been recycled (and may even be in use for something entirely different now). So you get a stale file handle
message because you asked for some nonexistent data.
When you perform a cd
operation, the shell reevaluates the inode location of whatever destination you give it. Now that your shell knows the new inode for the directory (and the new inodes for its contents), future requests for its contents will be valid.
Shorter way:
var queue = function (args){
typeof variableToCheck !== "undefined"? doSomething(args) : setTimeout(function () {queue(args)}, 2000);
};
You can also pass arguments
It sounds like you want an image
button:
<input type="image" src="logg.png" name="saveForm" class="btTxt submit" id="saveForm" />
Alternatively, you can use CSS to make the existing submit
button use your image as its background.
In any case, you don't want a separate <img />
element on the page.

Here is a util class for marshaling and unmarshaling objects. In my case it was a nested class, so I made it static JAXBUtils.
import javax.xml.bind.JAXB;
import java.io.StringReader;
import java.io.StringWriter;
public class JAXBUtils
{
/**
* Unmarshal an XML string
* @param xml The XML string
* @param type The JAXB class type.
* @return The unmarshalled object.
*/
public <T> T unmarshal(String xml, Class<T> type)
{
StringReader reader = new StringReader(xml);
return javax.xml.bind.JAXB.unmarshal(reader, type);
}
/**
* Marshal an Object to XML.
* @param object The object to marshal.
* @return The XML string representation of the object.
*/
public String marshal(Object object)
{
StringWriter stringWriter = new StringWriter();
JAXB.marshal(object, stringWriter);
return stringWriter.toString();
}
}
It's very easy:
numb = raw_input('Input Line: ')
fiIn = open('file.txt').readlines()
for lines in fiIn:
if numb == lines[0]:
print lines
Also had this issue out of the blue. Android studio was taking up 100% of CPU and in expo I had the following error:
Couldn't start project on Android: Error running adb: This computer is not authorized to debug the device. Please follow the instructions here to enable USB debugging: https://developer.android.com/studio/run/device.html#developer-device-options. If you are using Genymotion go to Settings -> ADB, select "Use custom Android SDK tools", and point it at your Android SDK directory.
Cold boot fixed it for me, like boltup_im_coding's answer. You can also cold boot this way if it's already running (with the black screen).
COUNTIF function will only count cells that contain numbers in your specified range.
COUNTA(range) will count all values in the list of arguments. Text entries and numbers are counted, even when they contain an empty string of length 0.
Example: Function in A7 =COUNTA(A1:A6)
Range:
A1 a
A2 b
A3 banana
A4 42
A5
A6
A7 4 -> result

Just use
If @searchType is null means 'return the whole table' then use
WHERE p.[Type] = @SearchType OR @SearchType is NULL
If @searchType is an empty string means 'return the whole table' then use
WHERE p.[Type] = @SearchType OR @SearchType = ''
If @searchType is null or an empty string means 'return the whole table' then use
WHERE p.[Type] = @SearchType OR Coalesce(@SearchType,'') = ''
Perhaps storing a blog post -> comments relation in a non-relational database is not really the best design.
You should probably store comments in a separate collection to blog posts anyway.

EDIT:
I've recently earned a "Good answer" badge for this answer. While my solution is simple and working, the cleanest way to run any program or shell script at login time is described in @trisweb's answer, unless, you want interactivity.
With automator solution you can do things like next:
so, asking to run a script or quit the app, asking passwords, running other automator workflows at login time, conditionally run applications at login time and so on...
Seems the answer(s) to this question are outdated with the release of Java 8.

PRIVATE("private", 0),
PUBLIC("public", 1),
DEFAULT("default", 2);
AccessLevel(final String name, final int value) {

return value;
}
static final Map<String, AccessLevel> names = Arrays.stream(AccessLevel.values())
.collect(Collectors.toMap(AccessLevel::getName, Function.identity()));
static final Map<Integer, AccessLevel> values = Arrays.stream(AccessLevel.values())
.collect(Collectors.toMap(AccessLevel::getValue, Function.identity()));
public static AccessLevel fromName(final String name) {

}
}
Depending on what you want to achieve with the removed scroll you could just fix the element that you want to remove scroll from (on click, or whatever other trigger you'd like to temporarily deactivate scroll)
I was searching around for a "temp no scroll" solution and for my needs, this solved it
make a class
.fixed{
position: fixed;
}
then with Jquery
var someTrigger = $('#trigger'); //a trigger button
var contentContainer = $('#content'); //element I want to temporarily remove scroll from
contentContainer.addClass('notfixed'); //make sure that the element has the "notfixed" class
//Something to trigger the fixed positioning. In this case we chose a button.
someTrigger.on('click', function(){
if(contentContainer.hasClass('notfixed')){
contentContainer.removeClass('notfixed').addClass('fixed');
}else if(contentContainer.hasClass('fixed')){
contentContainer.removeClass('fixed').addClass('notfixed');
};
});
I found that this was a simple enough solution that works well on all browsers, and also makes for simple use on portable devices (i.e. iPhones, tablets etc). Since the element is temporarily fixed, there is no scroll :)
NOTE! Depending on the placement of your "contentContainer" element you might need to adjust it from the left. Which can easily be done by adding a css left value to that element when the fixed class is active
contentContainer.css({
'left': $(window).width() - contentContainer.width()/2 //This would result in a value that is the windows entire width minus the element we want to "center" divided by two (since it's only pushed from one side)
});
If you don't want the hassle of using mail

The export default {...}
construction is just a shortcut for something like this:
const funcs = {
foo() { console.log('foo') },
bar() { console.log('bar') },
baz() { foo(); bar() }
}
export default funcs
It must become obvious now that there are no foo
, bar
or baz
functions in the module's scope. But there is an object named funcs
(though in reality it has no name) that contains these functions as its properties and which will become the module's default export.
So, to fix your code, re-write it without using the shortcut and refer to foo
and bar
as properties of funcs
:
const funcs = {
foo() { console.log('foo') },
bar() { console.log('bar') },
baz() { funcs.foo(); funcs.bar() } // here is the fix
}
export default funcs
Another option is to use this
keyword to refer to funcs
object without having to declare it explicitly, as @pawel has pointed out.
Yet another option (and the one which I generally prefer) is to declare these functions in the module scope. This allows to refer to them directly:
function foo() { console.log('foo') }
function bar() { console.log('bar') }
function baz() { foo(); bar() }
export default {foo, bar, baz}
And if you want the convenience of default export and ability to import items individually, you can also export all functions individually:
// util.js
export function foo() { console.log('foo') }
export function bar() { console.log('bar') }
export function baz() { foo(); bar() }
export default {foo, bar, baz}
// a.js, using default export
import util from './util'
util.foo()
// b.js, using named exports
import {bar} from './util'
bar()
Or, as @loganfsmyth suggested, you can do without default export and just use import * as util from './util'
to get all named exports in one object.
There are plenty of free portable GUI libraries, each with its own strengths and weaknesses:
Especially Qt has nice tutorials and tools which help you getting started. Enjoy!
Note, however, that you should avoid platform specific functionality such as the Win32 API or MFC. That ties you unnecessarily on a specific platform with almost no benefits.
You can use insert
:
a = [1,2,3]
a.insert(0,'x')
=> ['x',1,2,3]
Where the first argument is the index to insert at and the second is the value.
You dont need to give column names manually in xaml. Just set AutoGenerateColumns property to true and your list will be automatically binded to DataGrid. refer code. XAML Code:
<Grid>
<DataGrid x:Name="MyDatagrid" AutoGenerateColumns="True" Height="447" HorizontalAlignment="Left" Margin="20,85,0,0" VerticalAlignment="Top" Width="799" ItemsSource="{Binding Path=ListTest, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" CanUserAddRows="False"> </Grid>
C#
Public Class Test
{
public string m_field1_Test{get;set;}
public string m_field2_Test { get; set; }
public Test()
{
m_field1_Test = "field1";
m_field2_Test = "field2";
}
public MainWindow()
{
listTest = new List<Test>();
for (int i = 0; i < 10; i++)
{
obj = new Test();
listTest.Add(obj);
}
this.MyDatagrid.ItemsSource = ListTest;
InitializeComponent();
}
Edit 10th Dec 2015: As pointed out in the comments, ssi is deprecated since version 1.8. According to the documentation:
This tag has been deprecated and will be removed in Django 1.10. Use the include tag instead.
In my opinion, the right (best) answer to this question is the one from podshumok, as it explains why the behaviour of include when used along with inheritance.
However, I was somewhat surprised that nobody mentioned the ssi tag provided by the Django templating system, which is specifically designed for inline including an external piece of text. Here, inline means the external text will not be interpreted, parsed or interpolated, but simply "copied" inside the calling template.
Please, refer to the documentation for further details (be sure to check your appropriate version of Django in the selector at the lower right part of the page).
https://docs.djangoproject.com/en/dev/ref/templates/builtins/#ssi
From the documentation:
ssi Outputs the contents of a given file into the page. Like a simple include tag, {% ssi %} includes the contents of another file – which must be specified using an absolute path – in the current page
Beware also of the security implications of this technique and also of the required ALLOWED_INCLUDE_ROOTS define, which must be added to your settings files.
You want to loop on the .Rows, and access the column for the row like q("column")
Just:
For Each q In dtDataTable.Rows
strDetail = q("Detail")

Same thing, with jQuery:
$('#links a').each(function(){
var me = $(this);
me.html( me.text().replace(/(^\w+)/,'<strong>$1</strong>') );
});
or
$('#links a').each(function(){
var me = $(this)
, t = me.text().split(' ');
me.html( '<strong>'+t.shift()+'</strong> '+t.join(' ') );
});

Try using
git push --set-upstream origin <branch_name>
Otherwise
use
git push -u
will tell you what needs to be done.
After editing .gitignore
to match the ignored files, you can do git ls-files -ci --exclude-standard
to see the files that are included in the exclude lists; you can then do
git ls-files -ci --exclude-standard -z | xargs -0 git rm --cached
git ls-files -ci --exclude-standard | % { git rm --cached "$_" }
for /F "tokens=*" %a in ('git ls-files -ci --exclude-standard') do @git rm --cached "%a"
to remove them from the repository (without deleting them from disk).
Edit: You can also add this as an alias in your .gitconfig file so you can run it anytime you like. Just add the following line under the [alias] section (modify as needed for Windows or Mac):
apply-gitignore = !git ls-files -ci --exclude-standard -z | xargs -0 git rm --cached
(The -r
flag in xargs
prevents git rm
from running on an empty result and printing out its usage message, but may only be supported by GNU findutils. Other versions of xargs
may or may not have a similar option.)
Now you can just type git apply-gitignore
in your repo, and it'll do the work for you!

CHARINDEX:
SQL Server Execution Times (1):
CPU time = 5656 ms, elapsed time = 6418 ms.
SQL Server Execution Times (2):
CPU time = 5813 ms, elapsed time = 6114 ms.
SQL Server Execution Times (3):
CPU time = 5672 ms, elapsed time = 6108 ms.
PATINDEX:
SQL Server Execution Times (1):

Conclusion
The timings for CharIndex and PatIndex for 700k calls are within 3.5% of each other, so I don't think it would matter whichever is used. I use them interchangeably when both can work.
