I faced off the same problem when working with self-signed certs and client cert auth on .NET Core 2.2 and Docker Linux containers. Everything worked fine on my dev Windows machine, but in Docker I got such error:

System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure

Fortunately, the certificate was generated using a chain. Of course, you can always ignore this solution and use the above solutions.

So here is my solution:

1. I saved the certificate using Chrome on my computer in P7B format.

2. Convert certificate to PEM format using this command:
   openssl pkcs7 -inform DER -outform PEM -in <cert>.p7b -print_certs > ca_bundle.crt

3. Open the ca_bundle.crt file and delete all Subject recordings, leaving a clean file. Example below:

    -----BEGIN CERTIFICATE-----
    _BASE64 DATA_
    -----END CERTIFICATE-----
    -----BEGIN CERTIFICATE-----
    _BASE64 DATA_
    -----END CERTIFICATE-----
    -----BEGIN CERTIFICATE-----
    _BASE64 DATA_
    -----END CERTIFICATE-----

4. Put these lines to the Dockerfile (in the final steps):

    # Update system and install curl and ca-certificates
    RUN apt-get update && apt-get install -y curl && apt-get install -y ca-certificates
    # Copy your bundle file to the system trusted storage
    COPY ./ca_bundle.crt /usr/local/share/ca-certificates/ca_bundle.crt
    # During docker build, after this line you will get such output: 1 added, 0 removed; done.
    RUN update-ca-certificates

5. In the app:

    var address = new EndpointAddress("https://serviceUrl");                
    var binding = new BasicHttpsBinding
    {
        CloseTimeout = new TimeSpan(0, 1, 0),
        OpenTimeout = new TimeSpan(0, 1, 0),
        ReceiveTimeout = new TimeSpan(0, 1, 0),
        SendTimeout = new TimeSpan(0, 1, 0),
        MaxBufferPoolSize = 524288,
        MaxBufferSize = 65536,
        MaxReceivedMessageSize = 65536,
        TextEncoding = Encoding.UTF8,
        TransferMode = TransferMode.Buffered,
        UseDefaultWebProxy = true,
        AllowCookies = false,
        BypassProxyOnLocal = false,
        ReaderQuotas = XmlDictionaryReaderQuotas.Max,
        Security =
        {
            Mode = BasicHttpsSecurityMode.Transport,
            Transport = new HttpTransportSecurity
            {
                ClientCredentialType = HttpClientCredentialType.Certificate,
                ProxyCredentialType = HttpProxyCredentialType.None
            }
        }
    };
    var client = new MyWSClient(binding, address);
    client.ClientCredentials.ClientCertificate.Certificate = GetClientCertificate("clientCert.pfx", "passwordForClientCert");
    // Client certs must be installed
    client.ClientCredentials.ServiceCertificate.SslCertificateAuthentication = new X509ServiceCertificateAuthentication
    {
        CertificateValidationMode = X509CertificateValidationMode.ChainTrust,
        TrustedStoreLocation = StoreLocation.LocalMachine,
        RevocationMode = X509RevocationMode.NoCheck
    };

GetClientCertificate method:

private static X509Certificate2 GetClientCertificate(string clientCertName, string password)
{
    //Create X509Certificate2 object from .pfx file
    byte[] rawData = null;
    using (var f = new FileStream(Path.Combine(AppContext.BaseDirectory, clientCertName), FileMode.Open, FileAccess.Read))
    {
        var size = (int)f.Length;
        var rawData = new byte[size];
        f.Read(rawData, 0, size);
        f.Close();
    }
    return new X509Certificate2(rawData, password);
}

I actually had a similar issue, where we had to many trusted root certificates. Our fresh installed webserver had over a hunded. Our root started with the letter Z so it ended up at the end of the list.

The problem was that the IIS sent only the first twenty-something trusted roots to the client and truncated the rest, including ours. It was a few years ago, can't remember the name of the tool... it was part of the IIS admin suite, but Fiddler should do as well. After realizing the error, we removed a lot trusted roots that we don't need. This was done trial and error, so be careful what you delete.

After the cleanup everything worked like a charm.

Just as a follow up for anyone still running into this – I had added the ServicePointManager.SecurityProfile options as noted in the solution:

ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12;

And yet I continued to get the same “The request was aborted: Could not create SSL/TLS secure channel” error. I was attempting to connect to some older voice servers with HTTPS SOAP API interfaces (i.e. voice mail, IP phone systems etc… installed years ago). These only support SSL3 connections as they were last updated years ago.

One would think including SSl3 in the list of SecurityProtocols would do the trick here, but it didn’t. The only way I could force the connection was to include ONLY the Ssl3 protocol and no others:

ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;

Then the connection goes through – seems like a bug to me but this didn’t start throwing errors until recently on tools I provide for these servers that have been out there for years – I believe Microsoft has started rolling out system changes that have updated this behavior to force TLS connections unless there is no other alternative.

Anyway – if you’re still running into this against some old sites/servers, it’s worth giving it a try.

This happened to me when an web request endpoint was switched to another server that accepted TLS1.2 requests only. Tried so many attempts mostly found on Stackoverflow like

1. Registry Keys ,
2. Added :
   System.Net.ServicePointManager.SecurityProtocol |= System.Net.SecurityProtocolType.Tls12; to Global.ASX OnStart,
3. Added in Web.config.
4. Updated .Net framework to 4.7.2 Still getting same Exception.

The exception received did no make justice to the actual problem I was facing and found no help from the service operator.

To solve this I have to add a new Cipher Suite TLS_DHE_RSA_WITH_AES_256_GCM_SHA384 I have used IIS Crypto 2.0 Tool from here as shown below.

When I got this error, it was because the protocols (TLS versions) and/or cipher suites supported by the server were not enabled on (and possibly not even supported by) the device. For API 16-19, TLSv1.1 and TLSv1.2 are supported but not enabled by default. Once I enabled them for these versions, I still got the error because these versions don't support any of the ciphers on our instance of AWS CloudFront.

Since it's not possible to add ciphers to Android, we had to switch our CloudFront version from TLSv1.2_2018 to TLSv1.1_2016 (which still supports TLSv1.2; it just doesn't require it), which has four of the ciphers supported by the earlier Android versions, two of which are still considered strong.

At that point, the error disappeared and the calls went through (with TLSv1.2) because there was at least one protocol and at least one cipher that the device and server shared.

Refer to the tables on this page to see which protocols and ciphers are supported by and enabled on which versions of Android.

Now was Android really trying to use SSLv3 as implied by the "sslv3 alert handshake failure" part of the error message? I doubt it; I suspect this is an old cobweb in the SSL library that hasn't been cleaned out but I can't say for sure.

In order to enable TLSv1.2 (and TLSv1.1), I was able to use a much simpler SSLSocketFactory than the ones seen elsewhere (like NoSSLv3SocketFactory). It simply makes sure that the enabled protocols include all the supported protocols and that the enabled ciphers include all the supported ciphers (the latter wasn't necessary for me but it could be for others) - see configure() at the bottom. If you'd rather enable only the latest protocols, you can replace socket.supportedProtocols with something like arrayOf("TLSv1.1", "TLSv1.2") (likewise for the ciphers):

class TLSSocketFactory : SSLSocketFactory() {

    private val socketFactory: SSLSocketFactory

    init {
        val sslContext = SSLContext.getInstance("TLS")
        sslContext.init(null, null, null)
        socketFactory = sslContext.socketFactory
    }

    override fun getDefaultCipherSuites(): Array<String> {
        return socketFactory.defaultCipherSuites
    }

    override fun getSupportedCipherSuites(): Array<String> {
        return socketFactory.supportedCipherSuites
    }

    override fun createSocket(s: Socket, host: String, port: Int, autoClose: Boolean): Socket {
        return configure(socketFactory.createSocket(s, host, port, autoClose) as SSLSocket)
    }

    override fun createSocket(host: String, port: Int): Socket {
        return configure(socketFactory.createSocket(host, port) as SSLSocket)
    }

    override fun createSocket(host: InetAddress, port: Int): Socket {
        return configure(socketFactory.createSocket(host, port) as SSLSocket)
    }

    override fun createSocket(host: String, port: Int, localHost: InetAddress, localPort: Int): Socket {
        return configure(socketFactory.createSocket(host, port, localHost, localPort) as SSLSocket)
    }

    override fun createSocket(address: InetAddress, port: Int, localAddress: InetAddress, localPort: Int): Socket {
        return configure(socketFactory.createSocket(address, port, localAddress, localPort) as SSLSocket)
    }

    private fun configure(socket: SSLSocket): SSLSocket {
        socket.enabledProtocols = socket.supportedProtocols
        socket.enabledCipherSuites = socket.supportedCipherSuites
        return socket
    }
}

If you have seaborn installed, an easier method that does not require you to perform pivot:

import seaborn as sns

sns.lineplot(data=df, x='x', y='y', hue='color')

I solved this issue following the indication provided in the article http://blog.dev-area.net/2015/08/13/android-4-1-enable-tls-1-1-and-tls-1-2/ with little changes.

SSLContext context = SSLContext.getInstance("TLS");
context.init(null, null, null);
SSLSocketFactory noSSLv3Factory = null;
if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.KITKAT) {
    noSSLv3Factory = new TLSSocketFactory(sslContext.getSocketFactory());
} else {
    noSSLv3Factory = sslContext.getSocketFactory();
}
connection.setSSLSocketFactory(noSSLv3Factory);

This is the code of the custom TLSSocketFactory:

public static class TLSSocketFactory extends SSLSocketFactory {

    private SSLSocketFactory internalSSLSocketFactory;

    public TLSSocketFactory(SSLSocketFactory delegate) throws KeyManagementException, NoSuchAlgorithmException {
        internalSSLSocketFactory = delegate;
    }

    @Override
    public String[] getDefaultCipherSuites() {
        return internalSSLSocketFactory.getDefaultCipherSuites();
    }

    @Override
    public String[] getSupportedCipherSuites() {
        return internalSSLSocketFactory.getSupportedCipherSuites();
    }

    @Override
    public Socket createSocket(Socket s, String host, int port, boolean autoClose) throws IOException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(s, host, port, autoClose));
    }

    @Override
    public Socket createSocket(String host, int port) throws IOException, UnknownHostException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port));
    }

    @Override
    public Socket createSocket(String host, int port, InetAddress localHost, int localPort) throws IOException, UnknownHostException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port, localHost, localPort));
    }

    @Override
    public Socket createSocket(InetAddress host, int port) throws IOException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port));
    }

    @Override
    public Socket createSocket(InetAddress address, int port, InetAddress localAddress, int localPort) throws IOException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(address, port, localAddress, localPort));
    }

    /*
     * Utility methods
     */

    private static Socket enableTLSOnSocket(Socket socket) {
        if (socket != null && (socket instanceof SSLSocket)
                && isTLSServerEnabled((SSLSocket) socket)) { // skip the fix if server doesn't provide there TLS version
            ((SSLSocket) socket).setEnabledProtocols(new String[]{TLS_v1_1, TLS_v1_2});
        }
        return socket;
    }

    private static boolean isTLSServerEnabled(SSLSocket sslSocket) {
        System.out.println("__prova__ :: " + sslSocket.getSupportedProtocols().toString());
        for (String protocol : sslSocket.getSupportedProtocols()) {
            if (protocol.equals(TLS_v1_1) || protocol.equals(TLS_v1_2)) {
                return true;
            }
        }
        return false;
    }
}

Edit: Thank's to ademar111190 for the kotlin implementation (link)

class TLSSocketFactory constructor(
        private val internalSSLSocketFactory: SSLSocketFactory
) : SSLSocketFactory() {

    private val protocols = arrayOf("TLSv1.2", "TLSv1.1")

    override fun getDefaultCipherSuites(): Array<String> = internalSSLSocketFactory.defaultCipherSuites

    override fun getSupportedCipherSuites(): Array<String> = internalSSLSocketFactory.supportedCipherSuites

    override fun createSocket(s: Socket, host: String, port: Int, autoClose: Boolean) =
            enableTLSOnSocket(internalSSLSocketFactory.createSocket(s, host, port, autoClose))

    override fun createSocket(host: String, port: Int) =
            enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port))

    override fun createSocket(host: String, port: Int, localHost: InetAddress, localPort: Int) =
            enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port, localHost, localPort))

    override fun createSocket(host: InetAddress, port: Int) =
            enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port))

    override fun createSocket(address: InetAddress, port: Int, localAddress: InetAddress, localPort: Int) =
            enableTLSOnSocket(internalSSLSocketFactory.createSocket(address, port, localAddress, localPort))

    private fun enableTLSOnSocket(socket: Socket?) = socket?.apply {
        if (this is SSLSocket && isTLSServerEnabled(this)) {
            enabledProtocols = protocols
        }
    }

    private fun isTLSServerEnabled(sslSocket: SSLSocket) = sslSocket.supportedProtocols.any { it in protocols }

}

The answer I have finally found is that the SMTP service on the server is not using the same certificate as https.

The diagnostic steps I had read here make the assumption they use the same certificate and every time I've tried this in the past they have done and the diagnostic steps are exactly what I've done to solve the problem several times.

In this case those steps didn't work because the certificates in use were different, and the possibility of this is something I had never come across.

The solution is either to export the actual certificate from the server and then install it as a trusted certificate on my machine, or to get a different valid/trusted certificate for the SMTP service on the server. That is currently with our IT department who administer the servers to decide which they want to do.

In my case, my server was configured to work only in https mode, and error occured when I try to access http mode. So changing http://my-service to https://my-service helped.

Tomcat can work in 2 modes:

• BIO – blocking I/O (one thread per connection)
• NIO – non-blocking I/O (many more connections than threads)

Tomcat 7 is BIO by default, although consensus seems to be "don't use Bio because Nio is better in every way". You set this using the protocol parameter in the server.xml file.

• BIO will be HTTP/1.1 or org.apache.coyote.http11.Http11Protocol
• NIO will be org.apache.coyote.http11.Http11NioProtocol

If you're using BIO then I believe they should be more or less the same.

If you're using NIO then actually "maxConnections=1000" and "maxThreads=10" might even be reasonable. The defaults are maxConnections=10,000 and maxThreads=200. With NIO, each thread can serve any number of connections, switching back and forth but retaining the connection so you don't need to do all the usual handshaking which is especially time-consuming with HTTPS but even an issue with HTTP. You can adjust the "keepAlive" parameter to keep connections around for longer and this should speed everything up.

I got this error:

System.Net.Sockets.SocketException: An attempt was made to access a socket in a way forbidden by its access permissions

when the port was used by another program.

How about something like this

PROXY = "149.215.113.110:70"

webdriver.DesiredCapabilities.FIREFOX['proxy'] = {
    "httpProxy":PROXY,
    "ftpProxy":PROXY,
    "sslProxy":PROXY,
    "noProxy":None,
    "proxyType":"MANUAL",
    "class":"org.openqa.selenium.Proxy",
    "autodetect":False
}

# you have to use remote, otherwise you'll have to code it yourself in python to 
driver = webdriver.Remote("http://localhost:4444/wd/hub", webdriver.DesiredCapabilities.FIREFOX)

You can read more about it here.

Rather than adding a callback to ServicePointManager which will override certificate validation globally, you can set the callback on a local instance of HttpClient. This approach should only affect calls made using that instance of HttpClient.

Here is sample code showing how ignoring certificate validation errors for specific servers might be implemented in a Web API controller.

using System.Net.Http;
using System.Net.Security;
using System.Security.Cryptography.X509Certificates;

public class MyController : ApiController
{

    // use this HttpClient instance when making calls that need cert errors suppressed
    private static readonly HttpClient httpClient;

    static MyController()
    {
        // create a separate handler for use in this controller
        var handler = new HttpClientHandler();

        // add a custom certificate validation callback to the handler
        handler.ServerCertificateCustomValidationCallback = ((sender, cert, chain, errors) => ValidateCert(sender, cert, chain, errors));

        // create an HttpClient that will use the handler
        httpClient = new HttpClient(handler);
    }

    protected static ValidateCert(object sender, X509Certificate cert, X509Chain chain, SslPolicyErrors errors)
    {

        // set a list of servers for which cert validation errors will be ignored
        var overrideCerts = new string[]
        {
            "myproblemserver",
            "someotherserver",
            "localhost"
        };

        // if the server is in the override list, then ignore any validation errors
        var serverName = cert.Subject.ToLower();
        if (overrideCerts.Any(overrideName => serverName.Contains(overrideName))) return true;

        // otherwise use the standard validation results
        return errors == SslPolicyErrors.None;
    }

}

This is thrown when

... the peer was not able to identify itself (for example; no certificate, the particular cipher suite being used does not support authentication, or no peer authentication was established during SSL handshaking) this exception is thrown.

Probably the cause of this exception (where is the stacktrace) will show you why this exception is thrown. Most likely the default keystore shipped with Java does not contain (and trust) the root certificate of the TTP that is being used.

The answer is to retrieve the root certificate (e.g. from your browsers SSL connection), import it into the cacerts file and trust it using keytool which is shipped by the Java JDK. Otherwise you will have to assign another trust store programmatically.

I had a similar problem and wrote a detailed article about it. If anyone has the same problem, feel free to read my article.

https://developer-blog.net/administration/ssl-zertifikat-installieren/

It is a detailed problem description in German language.

Even shorter version of the solution from Dominic Zukiewicz:

ServicePointManager.ServerCertificateValidationCallback += (o, c, ch, er) => true;

But this means that you will trust all certificates. For a service that isn't just run locally, something a bit smarter will be needed. In the first instance you could use this code to just test whether it solves your problem.

This error is because your server doesn't have a valid SSL certificate. Hence we need to tell the client to use a different TrustManager. Here is a sample code:

SSLContext ctx = SSLContext.getInstance("TLS");
X509TrustManager tm = new X509TrustManager() {

    public void checkClientTrusted(X509Certificate[] xcs, String string) throws CertificateException {
    }

    public void checkServerTrusted(X509Certificate[] xcs, String string) throws CertificateException {
    }

    public X509Certificate[] getAcceptedIssuers() {
        return null;
    }
};
ctx.init(null, new TrustManager[]{tm}, null);
SSLSocketFactory ssf = new SSLSocketFactory(ctx,SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
ClientConnectionManager ccm = base.getConnectionManager();
SchemeRegistry sr = ccm.getSchemeRegistry();
sr.register(new Scheme("https", 443, ssf));

client = new DefaultHttpClient(ccm, base.getParams());

Instead of relying on the default virtual host mechanism in apache, you can define one last catchall virtualhost that uses an arbitrary ServerName and a wildcard ServerAlias, e.g.

ServerName catchall.mydomain.com
ServerAlias *.mydomain.com

In that way you can use SNI and apache will not send back the SSL warning.

Of course, this only works if you can describe all of your domains easily using a wildcard syntax.

I was also facing same issue. Below are the steps to resolve it.

1. check your openssl version

openssl version

2. If your version is below

OpenSSL 1.1.1h 22 Sep 2020

3. go to below link and download latest full version of openssl. openssl windows installer
4. After installation add openssl path at the top of 'PATH' variable in system path.
5. confirm your version is latest by opening new command prompt and running command in step 1
6. Now you're ready to run the command again and this time it will work.

I got this error too. I figured out that my version of PHP didn't have openssl compiled in, so simply adding the extension directive to php.ini wasn't enough. I don't know how you have to solve this in your particular case, but for me, I use macports, and the command was just:

sudo port install php5-openssl

Here is what fixed for me:

1) Make sure you are running Visual Studio as Administrator

2) Install and run winhttpcertcfg.exe to grant access

https://msdn.microsoft.com/en-us/library/windows/desktop/aa384088(v=vs.85).aspx

The command is similar to below: (enter your certificate subject and service name)

winhttpcertcfg -g -c LOCAL_MACHINE\MY -s "certificate subject" -a "NetworkService"
winhttpcertcfg -g -c LOCAL_MACHINE\MY -s "certificate subject" -a "LOCAL SERVICE"
winhttpcertcfg -g -c LOCAL_MACHINE\MY -s "certificate subject" -a "My Apps Service Account"

Python 3 (and 2)

import base64
a = 'eW91ciB0ZXh0'
base64.b64decode(a)

Python 2

A quick way to decode it without importing anything:

'eW91ciB0ZXh0'.decode('base64')

or more descriptive

>>> a = 'eW91ciB0ZXh0'
>>> a.decode('base64')
'your text'

This answer follows on to owlstead and Mat's responses. It applies to SE/EE installations, not ME/mobile/Android SSL.

Since no one has yet mentioned it, I'll mention the "production way" to fix this: Follow the steps from the AuthSSLProtocolSocketFactory class in HttpClient to update your trust store & key stores.

1. Import a trusted certificate and generate a truststore file

keytool -import -alias "my server cert" -file server.crt -keystore my.truststore

2. Generate a new key (use the same password as the truststore)

keytool -genkey -v -alias "my client key" -validity 365 -keystore my.keystore

3. Issue a certificate signing request (CSR)

keytool -certreq -alias "my client key" -file mycertreq.csr -keystore my.keystore

4. (self-sign or get your cert signed)

5. Import the trusted CA root certificate

keytool -import -alias "my trusted ca" -file caroot.crt -keystore my.keystore

6. Import the PKCS#7 file containg the complete certificate chain

keytool -import -alias "my client key" -file mycert.p7 -keystore my.keystore

7. Verify the resultant keystore file's contents

keytool -list -v -keystore my.keystore

If you don't have a server certificate, generate one in JKS format, then export it as a CRT file. Source: keytool documentation

keytool -genkey -alias server-alias -keyalg RSA -keypass changeit
    -storepass changeit -keystore my.keystore

keytool -export -alias server-alias -storepass changeit
    -file server.crt -keystore my.keystore

First you need NameVirtualHost ip:443 in you config file! You probably have one with 80 at the end, but you will also need one with 443.

Second you need a *.domain certificate (wildcard) (it is possible to make one)

Third you can make only something.domain webs in one ip (because of the certificate)

set your property using below code at the time of model creation i think your problem will be solved..and the time are not appear in database.you dont need to add any annotation.

private DateTime? dob;
        public DateTime? DOB
        {
            get
            {
                if (dob != null)
                {
                    return dob.Value.Date;
                }
                else
                {
                    return null;
                }

            }
            set { dob = value; }
        }

The problem comes from a misunderstanding of what variables are in Python. If you're used to most traditional languages, you have a mental model of what happens in the following sequence:

a = 1
a = 2

You believe that a is a memory location that stores the value 1, then is updated to store the value 2. That's not how things work in Python. Rather, a starts as a reference to an object with the value 1, then gets reassigned as a reference to an object with the value 2. Those two objects may continue to coexist even though a doesn't refer to the first one anymore; in fact they may be shared by any number of other references within the program.

When you call a function with a parameter, a new reference is created that refers to the object passed in. This is separate from the reference that was used in the function call, so there's no way to update that reference and make it refer to a new object. In your example:

def __init__(self):
    self.variable = 'Original'
    self.Change(self.variable)

def Change(self, var):
    var = 'Changed'

self.variable is a reference to the string object 'Original'. When you call Change you create a second reference var to the object. Inside the function you reassign the reference var to a different string object 'Changed', but the reference self.variable is separate and does not change.

The only way around this is to pass a mutable object. Because both references refer to the same object, any changes to the object are reflected in both places.

def __init__(self):         
    self.variable = ['Original']
    self.Change(self.variable)

def Change(self, var):
    var[0] = 'Changed'

Instead of doing

Reader in = new BufferedReader(
    new InputStreamReader(response.getEntity().getContent(), "UTF-8"));
StringBuilder builder= new StringBuilder();
char[] buf = new char[1000];
int l = 0;
while (l >= 0) {
    builder.append(buf, 0, l);
    l = in.read(buf);
}
JSONTokener tokener = new JSONTokener( builder.toString() );

You can do:

JSONTokener tokener = new JSONTokener(
                           IOUtils.toString(response.getEntity().getContent()) );

where IOUtils is from the commons IO library.

In order to add a label to the map you need to create a custom overlay. The sample at http://blog.mridey.com/2009/09/label-overlay-example-for-google-maps.html uses a custom class, Layer, that inherits from OverlayView (which inherits from MVCObject) from the Google Maps API. He has a revised version (adds support for visibility, zIndex and a click event) which can be found here: http://blog.mridey.com/2011/05/label-overlay-example-for-google-maps.html

The following code is taken directly from Marc Ridey's Blog (the revised link above).

Layer class

// Define the overlay, derived from google.maps.OverlayView
function Label(opt_options) {
  // Initialization
  this.setValues(opt_options);


  // Label specific
  var span = this.span_ = document.createElement('span');
  span.style.cssText = 'position: relative; left: -50%; top: -8px; ' +
  'white-space: nowrap; border: 1px solid blue; ' +
  'padding: 2px; background-color: white';


  var div = this.div_ = document.createElement('div');
  div.appendChild(span);
  div.style.cssText = 'position: absolute; display: none';
};
Label.prototype = new google.maps.OverlayView;


// Implement onAdd
Label.prototype.onAdd = function() {
  var pane = this.getPanes().overlayImage;
  pane.appendChild(this.div_);


  // Ensures the label is redrawn if the text or position is changed.
  var me = this;
  this.listeners_ = [
    google.maps.event.addListener(this, 'position_changed', function() { me.draw(); }),
    google.maps.event.addListener(this, 'visible_changed', function() { me.draw(); }),
    google.maps.event.addListener(this, 'clickable_changed', function() { me.draw(); }),
    google.maps.event.addListener(this, 'text_changed', function() { me.draw(); }),
    google.maps.event.addListener(this, 'zindex_changed', function() { me.draw(); }),
    google.maps.event.addDomListener(this.div_, 'click', function() {
      if (me.get('clickable')) {
        google.maps.event.trigger(me, 'click');
      }
    })
  ];
};

// Implement onRemove
Label.prototype.onRemove = function() {
 this.div_.parentNode.removeChild(this.div_);

 // Label is removed from the map, stop updating its position/text.
 for (var i = 0, I = this.listeners_.length; i < I; ++i) {
   google.maps.event.removeListener(this.listeners_[i]);
 }
};

// Implement draw
Label.prototype.draw = function() {
 var projection = this.getProjection();
 var position = projection.fromLatLngToDivPixel(this.get('position'));

 var div = this.div_;
 div.style.left = position.x + 'px';
 div.style.top = position.y + 'px';
 div.style.display = 'block';

 this.span_.innerHTML = this.get('text').toString();
};

Scrolling with content: Fiddle

Input elements have a property called disabled. When the form submits, just run some code like this:

var myInput = document.getElementById('myInput');
myInput.disabled = true;

left:auto;

This will default the left back to the browser default.

So if you have your Markup/CSS as:

<div class="myClass"></div>

.myClass
{
  position:absolute;
  left:0;
}

When setting RTL, you could change to:

<div class="myClass rtl"></div>

.myClass
{
  position:absolute;
  left:0;
}
.myClass.rtl
{
  left:auto;
  right:0;
}

There's no single method to do that. Use this:

@SuppressWarnings("unchecked")
public static <T extends Comparable> List<T> asSortedList(Collection<T> collection) {
  T[] array = collection.toArray(
    (T[])new Comparable[collection.size()]);
  Arrays.sort(array);
  return Arrays.asList(array);
}

In Swift, you can simply print a boolean value and it will be displayed as true or false.

let flag = true
print(flag) //true

The answer is already posted but note that this will pass the ArrayList by reference. So if you make any changes to the list in the function it will be affected to the original list also.

<access-modfier> <returnType> AnalyseArray(ArrayList<Integer> list)
{
//analyse the list
//return value
}

call it like this:

x=AnalyseArray(list);

or pass a copy of ArrayList:

x=AnalyseArray(list.clone());

There are a lot of dangerous answers on this page. Note that since SVN version 1.6, doing an update -r can cause tree conflicts, which rapidly escalates into a potentially data losing kafkeresque nightmare where you're googling for information on tree conflicts.

The correct way to revert to a version is:

svn merge -r HEAD:12345 .

Where 12345 is the version number. Don't forget the dot.

You need to register a domain(on GoDaddy for example) and put a load balancer in front of your ec2 instance - as DigaoParceiro said in his answer.

The issue is that domains generated by amazon on your ec2 instances are ephemeral. Today the domain is belonging to you, tomorrow it may not.

For that reason, let's encrypt throws an error when you try to register a certificate on amazon generated domain that states:

The ACME server refuses to issue a certificate for this domain name, because it is forbidden by policy

More details about this here: https://community.letsencrypt.org/t/policy-forbids-issuing-for-name-on-amazon-ec2-domain/12692/4

I believe that you are trying to connect to a something using SSL but that something is providing a certificate which is not verified by root certification authorities such as verisign.. In essence by default secure connections can only be established if the person trying to connect knows the counterparties keys or some other verndor such as verisign can step in and say that the public key being provided is indeed right..

ALL OS's trust a handful of certification authorities and smaller certificate issuers need to be certified by one of the large certifiers making a chain of certifiers if you get what I mean...

Anyways coming back to the point.. I had a similiar problem when programming a java applet and a java server ( Hopefully some day I will write a complete blogpost about how I got all the security to work :) )

In essence what I had to do was to extract the public keys from the server and store it in a keystore inside my applet and when I connected to the server I used this key store to create a trust factory and that trust factory to create the ssl connection. There are alterante procedures as well such as adding the key to the JVM's trusted host and modifying the default trust store on start up..

I did this around two months back and dont have source code on me right now.. use google and you should be able to solve this problem. If you cant message me back and I can provide you the relevent source code for the project .. Dont know if this solves your problem since you havent provided the code which causes these exceptions. Furthermore I was working wiht applets thought I cant see why it wont work on Serverlets...

P.S I cant get source code before the weekend since external SSH is disabled in my office :(

To even do better boolean mapping to Y/N, add to your hibernate configuration:

<!-- when using type="yes_no" for booleans, the line below allow booleans in HQL expressions: -->
<property name="hibernate.query.substitutions">true 'Y', false 'N'</property>

Now you can use booleans in HQL, for example:

"FROM " + SomeDomainClass.class.getName() + " somedomainclass " +
"WHERE somedomainclass.someboolean = false"

Just use this constructor of List<T>. It accepts any IEnumerable<T> as an argument.

string[] arr = ...
List<string> list = new List<string>(arr);

1. Declare a variable.
2. Store the checked property for the radio button.
3. Have a if condition.

Lets assume

private string isChecked; 
private webElement e; 
isChecked =e.findElement(By.tagName("input")).getAttribute("checked");
if(isChecked=="true")
{

}
else 
{

}

Hope this answer will be help for you. Let me know, if have any clarification in CSharp Selenium web driver.

The accepted answer here does not take into account the Kind of the DateTime instance. For example if your original DateTime instance was a UTC Kind then by making a new DateTime instance you will be making an Unknown Kind instance which will then be treated as local time based on server settings. Therefore the more proper way to get the first and last date of the month would be this:

var now = DateTime.UtcNow;
var first = now.Date.AddDays(-(now.Date.Day - 1));
var last = first.AddMonths(1).AddTicks(-1);

This way the original Kind of the DateTime instance is preserved.

You can use:

<?php
echo '<script>console.log("debug log")</script>';
?>

In case you are running it on Fedora or CentOS, this is what worked for me (PostgreSQL 9.6):

In terminal:

$ sudo visudo -f /etc/sudoers

modify the following text from:

Defaults    secure_path = /sbin:/bin:/usr/sbin:/usr/bin

to

Defaults    secure_path = /sbin:/bin:/usr/sbin:/usr/bin:/usr/pgsql-9.6/bin

exit, then:

$ printenv PATH

$ sudo su postgres

$ psql

To exit postgreSQL terminal, you need to digit:

$ \q

In addition, if you have a FileInfo fi, you can simply do:

string ext = fi.Extension;

and it'll hold the extension of the file (note: it will include the ., so a result of the above could be: .jpg .txt, and so on....

Swift 3.0 and Xcode 8.0

let imageData = UIImageJPEGRepresentation(imageView.image!, 1)

    let base64String = (imageData! as Data).base64EncodedString(options: NSData.Base64EncodingOptions(rawValue: 0))
    print(base64String)

This is my solution with prepared statements and stored procedure is returning several rows not only one value.

<?php

require 'config.php';
header('Content-type:application/json');
$connection->set_charset('utf8');

$mIds = $_GET['ids'];

$stmt = $connection->prepare("CALL sp_takes_string_returns_table(?)");
$stmt->bind_param("s", $mIds);

$stmt->execute();

$result = $stmt->get_result();
$response = $result->fetch_all(MYSQLI_ASSOC);
echo json_encode($response);

$stmt->close();
$connection->close();

You've almost done it. However setting flex: 0 0 <basis> declaration to the columns would prevent them from growing/shrinking; And the <basis> parameter would define the width of columns.

In addition, you could use CSS3 calc() expression to specify the height of columns with the respect to the height of the header.

#productShowcaseTitle {
  flex: 0 0 100%; /* Let it fill the entire space horizontally */
  height: 100px;
}

#productShowcaseDetail,
#productShowcaseThumbnailContainer {
  height: calc(100% - 100px); /* excluding the height of the header */
}

#productShowcaseContainer {_x000D_
  display: flex;_x000D_
  flex-flow: row wrap;_x000D_
_x000D_
  height: 600px;_x000D_
  width: 580px;_x000D_
}_x000D_
_x000D_
#productShowcaseTitle {_x000D_
  flex: 0 0 100%; /* Let it fill the entire space horizontally */_x000D_
  height: 100px;_x000D_
  background-color: silver;_x000D_
}_x000D_
_x000D_
#productShowcaseDetail {_x000D_
  flex: 0 0 66%; /* ~ 2 * 33.33% */_x000D_
  height: calc(100% - 100px); /* excluding the height of the header */_x000D_
  background-color: lightgray;_x000D_
}_x000D_
_x000D_
#productShowcaseThumbnailContainer {_x000D_
  flex: 0 0 34%;  /* ~ 33.33% */_x000D_
  height: calc(100% - 100px); /* excluding the height of the header */_x000D_
  background-color: black;_x000D_
}

<div id="productShowcaseContainer">_x000D_
  <div id="productShowcaseTitle"></div>_x000D_
  <div id="productShowcaseDetail"></div>_x000D_
  <div id="productShowcaseThumbnailContainer"></div>_x000D_
</div>

(Vendor prefixes omitted due to brevity)

Alternatively, if you could change your markup e.g. wrapping the columns by an additional <div> element, it would be achieved without using calc() as follows:

<div class="contentContainer"> <!-- Added wrapper -->
    <div id="productShowcaseDetail"></div>
    <div id="productShowcaseThumbnailContainer"></div>
</div>

#productShowcaseContainer {
  display: flex;
  flex-direction: column;
  height: 600px; width: 580px;
}

.contentContainer { display: flex; flex: 1; }
#productShowcaseDetail { flex: 3; }
#productShowcaseThumbnailContainer { flex: 2; }

#productShowcaseContainer {_x000D_
  display: flex;_x000D_
  flex-direction: column;_x000D_
_x000D_
  height: 600px;_x000D_
  width: 580px;_x000D_
}_x000D_
_x000D_
.contentContainer {_x000D_
  display: flex;_x000D_
  flex: 1;_x000D_
}_x000D_
_x000D_
#productShowcaseTitle {_x000D_
  height: 100px;_x000D_
  background-color: silver;_x000D_
}_x000D_
_x000D_
#productShowcaseDetail {_x000D_
  flex: 3;_x000D_
  background-color: lightgray;_x000D_
}_x000D_
_x000D_
#productShowcaseThumbnailContainer {_x000D_
  flex: 2;_x000D_
  background-color: black;_x000D_
}

<div id="productShowcaseContainer">_x000D_
  <div id="productShowcaseTitle"></div>_x000D_
_x000D_
  <div class="contentContainer"> <!-- Added wrapper -->_x000D_

The read in your script command is fine. However, you execute it in the pipeline, which means it is in a subshell, therefore, the variables it reads to are not visible in the parent shell. You can either

• move the rest of the script in the subshell, too:

  echo hello | { read str
    echo $str
  }
  

• or use command substitution to get the value of the variable out of the subshell

  str=$(echo hello)
  echo $str
  

  or a slightly more complicated example (Grabbing the 2nd element of ls)

  str=$(ls | { read a; read a; echo $a; })
  echo $str
  

good points already made here, but while there is lots of information about how rendering of margins is accomplished by the browser, the why isn't quite answered yet:

"Why is margin-top:-8px not the same as margin-bottom:8px?"

what we also could ask is:

Why doesn't a positive bottom margin 'bump up' preceding elements, whereas a positive top-margin 'bumps down' following elements?

so what we see is that there is a difference in the rendering of margins depending on the side they are applied to - top (and left) margins are different from bottom (and right) ones.

things are becoming clearer when having a (simplified) look at how styles are applied by the browser: elements are rendered top-down in the viewport, starting in the top left corner (let's stick with the vertical rendering for now, keeping in mind that the horizontal one is treated the same).

consider the following html:

<div class="box1"></div>
<div class="box2"></div>
<div class="box3"></div>

analogous to their position in code, these three boxes appear stacked 'top-down' in the browser (keeping things simple, we won't consider here the order property of the css3 'flex-box' module). so, whenever styles are applied to box 3, preceding element's positions (for box 1 and 2) have already been determined, and shouldn't be altered any more for the sake of rendering speed.

now, imagine a top margin of -10px for box 3. instead of shifting up all preceding elements to gather some space, the browser will just push box 3 up, so it's rendered on top of (or underneath, depending on the z-index) any preceding elements. even if performance wasn't an issue, moving all elements up could mean shifting them out of the viewport, thus the current scrolling position would have to be altered to have everything visible again.

same applies to a bottom margin for box 3, both negative and positive: instead of influencing already evaluated elements, only a new 'starting point' for upcoming elements is determined. thus setting a positive bottom margin will push the following elements down; a negative one will push them up.

It means "not equal to" (as in, the values in cells E37-N37 are not equal to "", or in other words, they are not empty.)

From arrays

An array is a container object that holds a fixed number of values of a single type. The length of an array is established when the array is created. After creation, its length is fixed. You've seen an example of arrays already, in the main method of the "Hello World!" application. This section discusses arrays in greater detail.

So in the case of a String array, once you create it with some length, you can't modify it, but you can add elements until you fill it.

String[] arr = new String[10]; // 10 is the length of the array.
arr[0] = "kk";
arr[1] = "pp";
...

So if your requirement is to add many objects, it's recommended that you use Lists like:

List<String> a = new ArrayList<String>();
a.add("kk");
a.add("pp"); 

Depending on how it will be used, you can either do this with two maps Map<K1, V> and Map<K2, V> or with two maps Map<K1, V> and Map<K2, K1>. If one of the keys is more permanent than the other, the second option may make more sense.

May be i did not fully understand the problem, but, centering all view inside a ConstraintLayout seems very simple. This is what I used:

<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center">

Last two lines did the trick!

REVOKE CONNECT will not prevent the connections from the db owner or superuser. So if you don't want anyone to connect the db, follow command may be useful.

alter database pilot allow_connections = off;

Then use:

SELECT pg_terminate_backend(pid)
FROM pg_stat_activity
WHERE datname = 'pilot';

A PendingIntent is a token that you give to another application (e.g. Notification Manager, Alarm Manager or other 3rd party applications), which allows this other application to use the permissions of your application to execute a predefined piece of code. To perform a broadcast via a pending intent so get a PendingIntent via PendingIntent.getBroadcast(). To perform an activity via an pending intent you receive the activity via PendingIntent.getActivity().

Just clear this folder: (only windows x64)

C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files

if your using php for the backend maybe you can use this code.

// Validate image file size
if (($_FILES["file-input"]["size"] > 2000000)) {
    $msg = "Image File Size is Greater than 2MB.";
    header("Location: ../product.php?error=$msg");
    exit();
}  

Just so you know...

Adding to the litany of woes with these classes, there is a rather interesting bug that's worth sharing.

I'm using a ViewPager to navigate a tree of items (select an item and the view pager animates scrolling to the right, and the next branch appears, navigate back, and the ViewPager scrolls in the opposite direction to return to the previous node).

The problem arises when I push and pop fragments off the end of the FragmentStatePagerAdapter. It's smart enough to notice that the items change, and smart enough to create and replace a fragment when the item has changed. But not smart enough to discard the fragment state, or smart enough to trim the internally saved fragment states when the adapter size changes. So when you pop an item, and push a new one onto the end, the fragment for the new item gets the saved state of the fragment for the old item, which caused absolute havoc in my code. My fragments carry data that may require a lot of work to refetch from the internet, so not saving state really wasn't an option.

I don't have a clean workaround. I used something like this:

  public void onSaveInstanceState(Bundle outState) {
    IFragmentListener listener = (IFragmentListener)getActivity();
    if (listener!= null)
    {
        if (!listener.isStillInTheAdapter(this.getAdapterItem()))
        {
            return; // return empty state.
        }

    }
    super.onSaveInstanceState(outState);

    // normal saving of state for flips and 
    // paging out of the activity follows
    ....
  }

An imperfect solution because the new fragment instance still gets a savedState Bundle, but at least it doesn't carry stale data.

Change extension_dir = "ext" to extension_dir = "C:/php/ext" in php.ini.

Quite simply, both lines create the object on the stack, rather than on the heap as 'new' does. The second line actually involves a second call to a copy constructor, so it should be avoided (it also needs to be corrected as indicated in the comments). You should use the stack for small objects as much as possible since it is faster, however if your objects are going to survive for longer than the stack frame, then it's clearly the wrong choice.

The by_row function from the purrrlyr package will do this for you.

This example demonstrates

myfn <- function(row) {
  #row is a tibble with one row, and the same number of columns as the original df
  l <- as.list(row)
  return(l)
}

list_of_lists <- purrrlyr::by_row(df, myfn, .labels=FALSE)$.out

By default, the returned value from myfn is put into a new list column in the df called .out. The $.out at the end of the above statement immediately selects this column, returning a list of lists.

I had this same issue, which led me here. In particular, for local development, I wanted to be able to do mysql -u root -p without sudo. I don't want to create a new user. I want to use root from a local PHP web app.

The error message is misleading, as there was nothing wrong with the default 'root'@'%' user privileges.

Instead, as several people mentioned in the other answers, the solution was simply to set bind-address=0.0.0.0 instead of bind-address=127.0.0.1 in my /etc/mysql/mysql.conf.d/mysqld.cnf config. No changes were otherwise required.

This may work as well.

SELECT * 
FROM myTable
WHERE CHARINDEX('mall', name) > 0
  OR CHARINDEX('mall', description) > 0

A natural key, if available, is usually best. So, if datetime/char uniquely identifies the row and both parts are meaningful to the row, that's great.

If just the datetime is meaningful, and the char is just tacked on to make it unique, then you might as well just go with an identify field.

Nobody seems to touch upon the fact that if you have many different 32-bit applications, the wow64 subsystem can map them anywhere in memory above 4G, so on a 64-bit windows with sufficient memory, you can run many more 32-bit applications than on a native 32-bit system.

The other answers provided here mention using @selector(localizedCaseInsensitiveCompare:) This works great for an array of NSString, however if you want to extend this to another type of object, and sort those objects according to a 'name' property, you should do this instead:

NSSortDescriptor *sort = [NSSortDescriptor sortDescriptorWithKey:@"name" ascending:YES];
sortedArray=[anArray sortedArrayUsingDescriptors:@[sort]];

Your objects will be sorted according to the name property of those objects.

If you want the sorting to be case insensitive, you would need to set the descriptor like this

NSSortDescriptor *sort = [NSSortDescriptor sortDescriptorWithKey:@"name" ascending:YES selector:@selector(caseInsensitiveCompare:)];

$toBeComparedDate = '2014-08-12';
$today = (new DateTime())->format('Y-m-d'); //use format whatever you are using
$expiry = (new DateTime($toBeComparedDate))->format('Y-m-d');

var_dump(strtotime($today) > strtotime($expiry)); //false or true

Maybe the problem is Sourcetree.

1. Go to Tools → Options

2. Uncheck "Check default remotes for updates every [10] minutes"

3. Restart Sourcetree!

In Tomcat 7 you have to add this to tomcat-users.xml (On windows 7 it is located by default installation here: c:\Program Files\Apache Software Foundation\Tomcat 7.0\conf\ )

<?xml version="1.0" encoding="UTF-8"?>
<tomcat-users>
  <role rolename="manager-gui"/>
  <role rolename="manager-script"/>
  <role rolename="manager-jmx"/>
  <role rolename="manager-status"/>
  <role rolename="admin-gui"/>
  <role rolename="admin-script"/>
  <user username="admin" password="admin" roles="manager-gui,manager-script,manager-jmx,manager-status,admin-gui,admin-script"/>
</tomcat-users>

NOTE that there shouldn't be ANY spaces between roles for admin, as this list should be comma separated.

So, instead of this (as suggested in some answers:

<user username="admin" password="admin" roles="manager-gui, manager-script, manager-jmx, manager-status, admin-gui, admin-script"/>

it MUST be like this:

  <user username="admin" password="admin" roles="manager-gui,manager-script,manager-jmx,manager-status,admin-gui,admin-script"/>

Beside of one view model in asp.net you can also make multiple partial views and assign different model view to every view, for example:

   @{
        Layout = null;
    }

    @model Person;

    <input type="text" asp-for="PersonID" />
    <input type="text" asp-for="PersonName" />

then another partial view Model for order model

    @{
        Layout = null;
     }

    @model Order;

    <input type="text" asp-for="OrderID" />
    <input type="text" asp-for="TotalSum" />

then in your main view load both partial view by

<partial name="PersonPartialView" />
<partial name="OrderPartialView" />

This worked for me

var serializeJSON = function(data) {
  return Object.keys(data).map(function (keyName) {
    return encodeURIComponent(keyName) + '=' + encodeURIComponent(data[keyName])
  }).join('&');
}

var response = fetch(url, {
  method: 'POST',
  body: serializeJSON({
    haha: 'input'
  })
});

Use:

date.format("MM/DD/YYYY") or date.format("MM-DD-YYYY")}

Other Supported formats for reference:

Months:

Mo 1st 2nd ... 11th 12th

MM 01 02 ... 11 12

MMM Jan Feb ... Nov Dec

MMMM January February ... November December

Day:

d 0 1 ... 5 6

do 0th 1st ... 5th 6th

dd Su Mo ... Fr Sa

ddd Sun Mon ... Fri Sat

dddd Sunday Monday ... Friday Saturday

Year:

YY 70 71 ... 29 30

YYYY 1970 1971 ... 2029 2030

Y 1970 1971 ... 9999 +10000 +10001

Use on :

$('#registered_participants').on('click', '.new_participant_form', function() {

So that the click is delegated to any element in #registered_participants having the class new_participant_form, even if it's added after you bound the event handler.

Here is how to do a quick check to see if n.fn.init[0] is caused by your DOM-elements not loading in time. Delay your selector function by wrapping it in setTimeout function like this:

function timeout(){ 

    ...your selector function that returns n.fn.init[0] goes here...

}

setTimeout(timeout, 5000)

This will cause your selector function to execute with a 5 second delay, which should be enough for pretty much anything to load.

This is just a coarse hack to check if DOM is ready for your selector function or not. This is not a (permanent) solution.

The preferred ways to check if the DOM is loaded before executing your function are as follows:

1) Wrap your selector function in

$(document).ready(function(){  ... your selector function...  };

2) If that doesn't work, use DOMContentLoaded

3) Try window.onload, which waits for all the images to load first, so its least preferred

window.onload = function () {  ... your selector function...  }

4) If you are waiting for a library to load that loads in several steps or has some sort of delay of its own, then you might need some complicated custom solution. This is what happened to me with "MathJax" library. This question discusses how to check when MathJax library loaded its DOM elements, if it is of any help.

5) Finally, you can stick with hard-coded setTimeout function, making it maybe 1-3 seconds. This is actually the very least preferred method in my opinion.

This list of fixes is probably far from perfect so everyone is welcome to edit it.

First, copy your GIF image into Asset Folder of your app create following classes and paste the code AnimationActivity: -

public class AnimationActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    InputStream stream = null;
    try {
        stream = getAssets().open("piggy.gif");
    } catch (IOException e) {
        e.printStackTrace();
    }
          GifWebView view = new GifWebView(this, "file:///android_asset    /piggy.gif");                 

    setContentView(view);
}
}

I Think It Might Help You... :)

Another way is to use a logging platform that has the capabilities of opening and closing logs. This can give much of flexibility sometimes even on a production app which logs should be open and which closed depending on which issues you have for example:

• Shipbook (disclaimer: I'm the author of this package)

A Magento Module is a group of directories containing blocks, controllers, helpers, and models that are needed to create a specific store feature. It is the unit of customization in the Magento platform. Magento Modules can be created to perform multiple functions with supporting logic to influence user experience and storefront appearance. It has a life cycle that allows them to be installed, deleted, or disabled. From the perspective of both merchants and extension developers, modules are the central unit of the Magento platform.

Declaration of Module

We have to declare the module by using the configuration file. As Magento 2 search for configuration module in etc directory of the module. So now we will create configuration file module.xml.

The code will look like this:

<?xml version="1.0"?> <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd"> <module name="Cloudways_Mymodule" setup_version="1.0.0"></module> </config>

Registration of Module The module must be registered in the Magento 2 system by using Magento Component Registrar class. Now we will create the file registration.php in the module root directory:

app/code/Cloudways/Mymodule/registration.php

The Code will look like this:

?php
\Magento\Framework\Component\ComponentRegistrar::register(
\Magento\Framework\Component\ComponentRegistrar::MODULE,
'Cloudways_Mymodule',
__DIR__
);

Check Module Status After following the steps above, we would have created a simple module. Now we are going to check the status of the module and whether it is enabled or disabled by using the following command line:

php bin/magento module:status

php bin/magento module:enable Cloudways_Mymodule

I'll add my solution here. We can use floor when values are above 0 and ceil when they are less than zero:

function truncateToInt(x)
{
    if(x > 0)
    {
         return Math.floor(x);
    }
    else
    {
         return Math.ceil(x);
    }
 }

Then:

y = truncateToInt(2.9999); // results in 2
y = truncateToInt(-3.118); //results in -3

Notice: This answer was written when Math.trunc(x) was fairly new and not supported by a lot of browsers. Today, modern browsers support Math.trunc(x).

You want  win.Sleep(milliseconds), methinks.

Yeah, you definitely don't want to do a busy-wait like you describe.

Answers provided here as which camera api to use are wrong. Or better to say they are insufficient.

Some phones (for example Samsung Galaxy S6) could be above api level 21 but still may not support Camera2 api.

CameraCharacteristics mCameraCharacteristics = mCameraManager.getCameraCharacteristics(mCameraId);
Integer level = mCameraCharacteristics.get(CameraCharacteristics.INFO_SUPPORTED_HARDWARE_LEVEL);
if (level == null || level == CameraCharacteristics.INFO_SUPPORTED_HARDWARE_LEVEL_LEGACY) {
    return false;
}

CameraManager class in Camera2Api has a method to read camera characteristics. You should check if hardware wise device is supporting Camera2 Api or not.

But there are more issues to handle if you really want to make it work for a serious application: Like, auto-flash option may not work for some devices or battery level of the phone might create a RuntimeException on Camera or phone could return an invalid camera id and etc.

So best approach is to have a fallback mechanism as for some reason Camera2 fails to start you can try Camera1 and if this fails as well you can make a call to Android to open default Camera for you.

You could also use the coalesce function. I tested this in PostgreSQL, but it should also work for MySQL or MS SQL server.

INNER JOIN x ON coalesce(x.qid, -1) = coalesce(y.qid, -1)

This will replace NULL with -1 before evaluating it. Hence there must be no -1 in qid.

I faced 1.40s while working with a pure laravel in development area!

the problem was using: php artisan serve to run the webserver

when I used apache webserver (or NGINX) instead for the same code I got it down to 153ms

var fields = {
teste:
{
    Acess:
    {
        Edit: true,
      View: false

      }
 },
teste1:
{
    Acess:
    {
        Edit: false,
      View: false

      }
  }
};

console.log(find(fields,'teste'));
function find(fields,field){
    for(key in fields){
        if(key == field){
        return true;
    }
}
return false;
}

If you have one Object with multiply objects inside, if you want know if some object are include on Master object, just put find(MasterObject,'Object to Search'), this function will return the response if exist or not (TRUE or FALSE), I hope help with this, can see the exemple on JSFiddle.

I have made this function. It works fine but returns string.

function show_float_val(val,upto = 2){
  var val = parseFloat(val);
  return val.toFixed(upto);
}

Interesting, I didn't know make would default to using the C compiler given rules regarding source files.

Anyway, a simple solution that demonstrates simple Makefile concepts would be:

HEADERS = program.h headers.h

default: program

program.o: program.c $(HEADERS)
    gcc -c program.c -o program.o

program: program.o
    gcc program.o -o program

clean:
    -rm -f program.o
    -rm -f program

(bear in mind that make requires tab instead of space indentation, so be sure to fix that when copying)

However, to support more C files, you'd have to make new rules for each of them. Thus, to improve:

HEADERS = program.h headers.h
OBJECTS = program.o

default: program

%.o: %.c $(HEADERS)
    gcc -c $< -o $@

program: $(OBJECTS)
    gcc $(OBJECTS) -o $@

clean:
    -rm -f $(OBJECTS)
    -rm -f program

I tried to make this as simple as possible by omitting variables like $(CC) and $(CFLAGS) that are usually seen in makefiles. If you're interested in figuring that out, I hope I've given you a good start on that.

Here's the Makefile I like to use for C source. Feel free to use it:

TARGET = prog
LIBS = -lm
CC = gcc
CFLAGS = -g -Wall

.PHONY: default all clean

default: $(TARGET)
all: default

OBJECTS = $(patsubst %.c, %.o, $(wildcard *.c))
HEADERS = $(wildcard *.h)

%.o: %.c $(HEADERS)
    $(CC) $(CFLAGS) -c $< -o $@

.PRECIOUS: $(TARGET) $(OBJECTS)

$(TARGET): $(OBJECTS)
    $(CC) $(OBJECTS) -Wall $(LIBS) -o $@

clean:
    -rm -f *.o
    -rm -f $(TARGET)

It uses the wildcard and patsubst features of the make utility to automatically include .c and .h files in the current directory, meaning when you add new code files to your directory, you won't have to update the Makefile. However, if you want to change the name of the generated executable, libraries, or compiler flags, you can just modify the variables.

In either case, don't use autoconf, please. I'm begging you! :)

In the manual for GNU make, they talk about this specific example when describing the value function:

The value function provides a way for you to use the value of a variable without having it expanded. Please note that this does not undo expansions which have already occurred; for example if you create a simply expanded variable its value is expanded during the definition; in that case the value function will return the same result as using the variable directly.

The syntax of the value function is:

 $(value variable)

Note that variable is the name of a variable; not a reference to that variable. Therefore you would not normally use a ‘$’ or parentheses when writing it. (You can, however, use a variable reference in the name if you want the name not to be a constant.)

The result of this function is a string containing the value of variable, without any expansion occurring. For example, in this makefile:

 FOO = $PATH

 all:
         @echo $(FOO)
         @echo $(value FOO)

The first output line would be ATH, since the “$P” would be expanded as a make variable, while the second output line would be the current value of your $PATH environment variable, since the value function avoided the expansion.

This is the cleanest approach

let dat = new Date() _x000D_
let copyOf = new Date(dat.valueOf())_x000D_
_x000D_
console.log(dat);_x000D_
console.log(copyOf);

You use input.files property. It's a collection of File objects and each file has a name property:

onmouseout="for (var i = 0; i < this.files.length; i++) alert(this.files[i].name);"

There's no need for "else" in this case:

IF EXISTS(SELECT *  FROM  table1  WHERE Name='John' ) return 1
return 0

A great Spring MVC quickstart archetype is available on GitHub, courtesy of kolorobot. Good instructions are provided on how to install it to your local Maven repo and use it to create a new Spring MVC project. He’s even helpfully included the Tomcat 7 Maven plugin in the archetypical project so that the newly created Spring MVC can be run from the command line without having to manually deploy it to an application server.

Kolorobot’s example application includes the following:

• No-xml Spring MVC 3.2 web application for Servlet 3.0 environment
• Apache Tiles with configuration in place,
• Bootstrap
• JPA 2.0 (Hibernate/HSQLDB)
• JUnit/Mockito
• Spring Security 3.1

You can stop the 2-line separation in the output by using

    with open('t.ini') as f:
       for line in f:
           print line.strip()
           if 'str' in line:
              break

Based on the answer from #squiguy, to get a true timestamp I would type cast it from float.

>>> import time
>>> ts = int(time.time())
>>> print(ts)
1389177318

At least that's the concept.

You need to make your regex pattern 'non-greedy' by adding a '?' after the '.+'

By default, '*' and '+' are greedy in that they will match as long a string of chars as possible, ignoring any matches that might occur within the string.

Non-greedy makes the pattern only match the shortest possible match.

See Watch Out for The Greediness! for a better explanation.

Or alternately, change your regex to

\(([^\)]+)\)

which will match any grouping of parens that do not, themselves, contain parens.

for WPF: (where lblInfo is a label, chkRun is a checkBox)

this.Topmost is just to keep my app on the top of other windows, you will also need to add a using statement " using Microsoft.Win32; ", StartupWithWindows is my application's name

true, this option is not available in any version of MS ppt.Now the solution is that You put your different sized slide in other file and put a hyperlink in first file.

HTTP 304 is "not modified". Your web server is basically telling the browser "this file hasn't changed since the last time you requested it." Whereas an HTTP 200 is telling the browser "here is a successful response" - which should be returned when it's either the first time your browser is accessing the file or the first time a modified copy is being accessed.

Git GUI has a PUSH button - pardon the pun, and the dialog box it opens has a checkbox for tags.

I pushed a branch from the command line, without tags, and then tried again pushing the branch using the --follow-tags option descibed above. The option is described as following annotated tags. My tags were simple tags.

I'd fixed something, tagged the commit with the fix in, (so colleagues can cherry pick the fix,) then changed the software version number and tagged the release I created (so colleagues can clone that release).

Git returned saying everything was up-to-date. It did not send the tags! Perhaps because the tags weren't annotated. Perhaps because there was nothing new on the branch.

When I did a similar push with Git GUI, the tags were sent.

For the time being, I am going to be pushing my changes to my remotes with Git GUI and not with the command line and --follow-tags.

  function isBooleanString(val) {
    if (val === "true" || val === "false"){
      return true

isBooleanString("true") // true
isBooleanString("false") // true

isBooleanString("blabla") // false

The date function can return this if you specify the format correctly:

$daynum = date("w", strtotime("wednesday"));

will return 0 for Sunday through to 6 for Saturday.

An alternative format is:

$daynum = date("N", strtotime("wednesday"));

which will return 1 for Monday through to 7 for Sunday (this is the ISO-8601 represensation).

When running into this error and reviewing my dataset which appeared to have no missing data, I discovered that a few of my entries had the special character "#" which derailed importing the data. Once I removed the "#" from the offending cells, the data imported without issue.

If you installed from source, you can issue the following command:

sudo make uninstall

If you followed the instructions on https://github.com/nodejs/node/wiki to install to your $HOME/local/node, then you have to type the following before the line above:

./configure --prefix=$HOME/local/node

You could turn '%string%' to contains(), 'string%' to startsWith() and '%string"' to endsWith().

You should also run toLowerCase() on both the string and pattern as LIKE is case-insenstive.

Not sure how you'd handle '%string%other%' except with a Regular Expression though.

If you're using Regular Expressions:

• Quote the string before you replace the % characters
• Watch out for escaped characters in the LIKE String

Here's an example of how you'd use filter within your AngularJS JavaScript (rather than in an HTML element).

In this example, we have an array of Country records, each containing a name and a 3-character ISO code.

We want to write a function which will search through this list for a record which matches a specific 3-character code.

Here's how we'd do it without using filter:

$scope.FindCountryByCode = function (CountryCode) {
    //  Search through an array of Country records for one containing a particular 3-character country-code.
    //  Returns either a record, or NULL, if the country couldn't be found.
    for (var i = 0; i < $scope.CountryList.length; i++) {
        if ($scope.CountryList[i].IsoAlpha3 == CountryCode) {
            return $scope.CountryList[i];
        };
    };
    return null;
};

Yup, nothing wrong with that.

But here's how the same function would look, using filter:

$scope.FindCountryByCode = function (CountryCode) {
    //  Search through an array of Country records for one containing a particular 3-character country-code.
    //  Returns either a record, or NULL, if the country couldn't be found.

    var matches = $scope.CountryList.filter(function (el) { return el.IsoAlpha3 == CountryCode; })

    //  If 'filter' didn't find any matching records, its result will be an array of 0 records.
    if (matches.length == 0)
        return null;

    //  Otherwise, it should've found just one matching record
    return matches[0];
};

Much neater.

Remember that filter returns an array as a result (a list of matching records), so in this example, we'll either want to return 1 record, or NULL.

Hope this helps.

Here is a simpler option that works when I encounter this.

After you create the connection, select the connection and open the Properties. In the Expressions category find Password. Re-enter the password and hit Enter. It will now be saved to the connection.

Edit: I changed it to work for dynamically added elements using .on() in jQuery 1.7 or above:

$(document).on("contextmenu", ".element", function(e){
   alert('Context Menu event has fired!');
   return false;
});

Demo: jsfiddle.net/Kn9s7/5

[Start of original post] This is what worked for me:

$('.element').bind("contextmenu",function(e){
   alert('Context Menu event has fired!');
   return false;
}); 

In case you are into multiple solutions ^^

Edit: Tim Down brings up a good point that it's not always going to be a right-click that fires the contextmenu event, but also when the context menu key is pressed (which is arguably a replacement for a right-click)

Since this seems to be the go-to thread for the problem regarding missing 'InitializeComponent', I'll include my answer here.

I too was having this issue and I've tried everything I found here and in all other Forums that Google could find, however none resolved the issue for me. After two hours of trying everything, I finally figured out what was wrong with my setup.

In our project, we are using Metro components from MahApps. The view that was giving me trouble was a view inheriting from MetroWindow, like this:

<Controls:MetroWindow x:Class="ProjectNamespace.MyView"
                      xmlns:Controls="http://metro.mahapps.com/winfx/xaml/controls"
                      ... >

Now, I have defined my static resources as

<Controls:MetroWindow.Resources>
    <prop:Resources x:Key="LocalizedStrings"/>
    ...
</Controls:MetroWindow.Resources>

That's how I've defined Resources in UserControls in all my other views, so that's what I assumed will work.

That was, however, not the case with Controls:MetroWindow! There I absolutely needed the resource definition as follows:

<Controls:MetroWindow.Resources>
    <ResourceDictionary>
        <prop:Resources x:Key="LocalizedStrings"/>
        ...
    </ResourceDictionary>
</Controls:MetroWindow.Resources>

So my issue, in summary, was a missing <ResourceDictionary> tag. I really don't know why this produced the 'InitializeComponent' error and it weirdly didn't even produce it on every machine of mine, but that's how I fixed it. Hope this helps (the remaining 0.001% of people encountering this issue).

Probably nicer to use an extension method:

public static class StringExtensions
{
    public static string Right(this string str, int length)
    {
        return str.Substring(str.Length - length, length);
    }
}

Usage

string myStr = "PER 343573";
string subStr = myStr.Right(6);

Expanding on Atrur Klesun's idea... you can just access it by its name if you use getElementById to reach the form. In one line:

document.getElementById('form_id').elements['select_name'].value;

I used it like so for radio buttons and worked fine. I guess it's the same here.

This has been answered and accepted, but if someone is still wondering why are things a bit messed up today, you'll have to read this:

http://webaim.org/blog/user-agent-string-history/

It gives a good idea of how gecko, webkit and other major rendering engines evolved and what led to the current state of messed up user-agent strings.

Quoting the last paragraph for TL;DR purposes:

And then Google built Chrome, and Chrome used Webkit, and it was like Safari, and wanted pages built for Safari, and so pretended to be Safari. And thus Chrome used WebKit, and pretended to be Safari, and WebKit pretended to be KHTML, and KHTML pretended to be Gecko, and all browsers pretended to be Mozilla, and Chrome called itself Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/525.13 (KHTML, like Gecko) Chrome/0.2.149.27 Safari/525.13, and the user agent string was a complete mess, and near useless, and everyone pretended to be everyone else, and confusion abounded.

Literally, just restarted IntelliJ after it kept showing this "install git" message after I have pressed and installed git, and it disappeared, and git works

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/.

The code marked @Before is executed before each test, while @BeforeClass runs once before the entire test fixture. If your test class has ten tests, @Before code will be executed ten times, but @BeforeClass will be executed only once.

In general, you use @BeforeClass when multiple tests need to share the same computationally expensive setup code. Establishing a database connection falls into this category. You can move code from @BeforeClass into @Before, but your test run may take longer. Note that the code marked @BeforeClass is run as static initializer, therefore it will run before the class instance of your test fixture is created.

In JUnit 5, the tags @BeforeEach and @BeforeAll are the equivalents of @Before and @BeforeClass in JUnit 4. Their names are a bit more indicative of when they run, loosely interpreted: 'before each tests' and 'once before all tests'.

Call the child activity Intent using the startActivityForResult() method call

There is an example of this here: http://developer.android.com/training/notepad/notepad-ex2.html

and in the "Returning a Result from a Screen" of this: http://developer.android.com/guide/faq/commontasks.html#opennewscreen

In my case the Exception occurred because I had removed the "hibernate.enable_lazy_load_no_trans=true" in the "hibernate.properties" file...

I had made a copy and paste typo...

You can also use Select-Object like so:

Get-ChildItem "C:\WINDOWS\System32" *.txt -Recurse | Select-Object FullName

A Fiddle would have been more helpful nevertheless from what I understand, I guess what you need is persistent headers, look into this

Yet another solution, assuming the number of items in the folder is not huge:

tar -czf workspace.tar.gz `ls -A`

(ls -A prints normal and hidden files but not "." and ".." as ls -a does.)

I had this problem tonight with android and after looking at the javadoc solutions I came up with this real working solution just for people like me that need a little more than a javadoc explanation.

Here's a working example with an actual interface using android java. It checks the activity that called implemented the AboutDialogListener interface before attempting to cast the AboutDialogListener field.

public class About extends DialogFragment implements OnClickListener,
    OnCheckedChangeListener {

public static final String FIRST_RUN_ABOUT = "com.gosylvester.bestrides.firstrunabout";


public interface AboutDialogListener {
    void onFinishEditDialog(Boolean _Checked);
}

private AboutDialogListener adl;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    Activity a = this.getActivity();
    if (AboutDialogListener.class.isInstance(a)) {
        adl = (AboutDialogListener) a;
        }
}

... Later I check if the field adl is !null before calling the interface

@Override
public void onStop() {
    super.onStop();
    sharedPref.edit().putBoolean(About.FIRST_RUN_ABOUT, _Checked).commit();
    // if there is an interface call it.
    if (adl != null) {
        adl.onFinishEditDialog(is_Checked());
    }
}

This is an example that will work on most browsers.
Basically you use two background colors, the first one starting from 0% and ending at 50% and the second one starting from 51% and ending at 100%

I'm using horizontal orientation:

background: #000000;
background: -moz-linear-gradient(left,  #000000 0%, #000000 50%, #ffffff 51%, #ffffff 100%);
background: -webkit-gradient(linear, left top, right top, color-stop(0%,#000000), color-stop(50%,#000000), color-stop(51%,#ffffff), color-stop(100%,#ffffff));
background: -webkit-linear-gradient(left,  #000000 0%,#000000 50%,#ffffff 51%,#ffffff 100%);
background: -o-linear-gradient(left,  #000000 0%,#000000 50%,#ffffff 51%,#ffffff 100%);
background: -ms-linear-gradient(left,  #000000 0%,#000000 50%,#ffffff 51%,#ffffff 100%);
background: linear-gradient(to right,  #000000 0%,#000000 50%,#ffffff 51%,#ffffff 100%);
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#000000', endColorstr='#ffffff',GradientType=1 );

Oauth is definitely gaining momentum and becoming popular among enterprise APIs as well. In the app and data driven world, Enterprises are exposing APIs more and more to the outer world in line with Google, Facebook, twitter. With this development a 3 way triangle of authentication gets formed

1) API provider- Any enterprise which exposes their assets by API, say Amazon,Target etc 2) Developer - The one who build mobile/other apps over this APIs 3) The end user- The end user of the service provided by the - say registered/guest users of Amazon

Now this develops a situation related to security - (I am listing few of these complexities) 1) You as an end user wants to allow the developer to access APIs on behalf of you. 2) The API provider has to authenticate the developer and the end user 3) The end user should be able to grant and revoke the permissions for the consent they have given 4) The developer can have varying level of trust with the API provider, in which the level of permissions given to her is different

The Oauth is an authorization framework which tries to solve the above mentioned problem in a standard way. With the prominence of APIs and Apps this problem will become more and more relevant and any standard which tries to solve it - be it ouath or any other - will be something to care about as an API provider/developer and even end user!

Following on @Anorak answer, i added this extension to String and sent an inset as a parameter, because a lot of times you will need a padding to your text. Anyway, maybe some you will find this usefull.

extension String {

    func heightForWithFont(font: UIFont, width: CGFloat, insets: UIEdgeInsets) -> CGFloat {

        let label:UILabel = UILabel(frame: CGRectMake(0, 0, width + insets.left + insets.right, CGFloat.max))
        label.numberOfLines = 0
        label.lineBreakMode = NSLineBreakMode.ByWordWrapping
        label.font = font
        label.text = self

        label.sizeToFit()
        return label.frame.height + insets.top + insets.bottom
    }
}

var ip = req.headers['x-forwarded-for'] || 
     req.connection.remoteAddress || 
     req.socket.remoteAddress ||
     (req.connection.socket ? req.connection.socket.remoteAddress : null);

Note that sometimes you can get more than one IP address in req.headers['x-forwarded-for']. Also, an x-forwarded-for header will not always be set which may throw an error.

The general format of the field is:

x-forwarded-for: client, proxy1, proxy2, proxy3

where the value is a comma+space separated list of IP addresses, the left-most being the original client, and each successive proxy that passed the request adding the IP address where it received the request from. In this example, the request passed through proxy1, proxy2, and then proxy3. proxy3 appears as remote address of the request.

This is the solution suggested by Arnav Gupta with a fix Martin has suggested below in the comments for cases when x-forwarded-for is not set :

var ip = (req.headers['x-forwarded-for'] || '').split(',').pop().trim() || 
         req.connection.remoteAddress || 
         req.socket.remoteAddress || 
         req.connection.socket.remoteAddress

Suggestion using modern JS:

• processing x-forwarded-for only if set, if so, take the first address
• other parameters use optional chaining (?.)

const parseIp = (req) =>
    (typeof req.headers['x-forwarded-for'] === 'string'
        && req.headers['x-forwarded-for'].split(',').shift())
    || req.connection?.remoteAddress
    || req.socket?.remoteAddress
    || req.connection?.socket?.remoteAddress

console.log(parseIp(req))
// => 127.0.0.1

The problem with the new version of QuickText seems to be that it is set to react to the TAB key. Previously it was set to use CTRL-ENTER. If you change the key combination in the shortcut mapper then your TAB key should start working again, and QuickText should also work (with whatever new key you've assigned).

There's no need for Prototype here: JavaScript has for..in loops. If you're not sure that no one messed with Object.prototype, check hasOwnProperty() as well, ie

for(var prop in obj) {
    if(obj.hasOwnProperty(prop))
        doSomethingWith(obj[prop]);
}

Build-timeout Plugin can come handy for such cases. It will kill the job automatically if it takes too long.

Just look for my solution on jsfiddle, it is based on csslayout

Well, this one liner might qualify (uses Guava Ranges)

ContiguousSet<Integer> integerList = ContiguousSet.create(Range.closedOpen(0, 10), DiscreteDomain.integers());
System.out.println(integerList);

This doesn't create a List<Integer>, but ContiguousSet offers much the same functionality, in particular implementing Iterable<Integer> which allows foreach implementation in the same way as List<Integer>.

In older versions (somewhere before Guava 14) you could use this:

ImmutableList<Integer> integerList = Ranges.closedOpen(0, 10).asSet(DiscreteDomains.integers()).asList();
System.out.println(integerList);

Both produce:

[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

Performance wise, this should be comparable. Use Select statement and Sort to get a list and then pick the first or last (depending on your sort order).

var col = dt.Select("AccountLevel", "AccountLevel ASC");

var min = col.First();
var max = col.Last();

This answer did the trick for me http://view.jquerymobile.com/master/demos/faq/injected-content-is-not-enhanced.php.

In the context of a multi-pages template, I modify the content of a <div id="foo">...</div> in a Javascript 'pagebeforeshow' handler and trigger a refresh at the end of the script:

$(document).bind("pagebeforeshow", function(event,pdata) {
  var parsedUrl = $.mobile.path.parseUrl( location.href );
  switch ( parsedUrl.hash ) {
    case "#p_02":
      ... some modifications of the content of the <div> here ...
      $("#foo").trigger("create");
    break;
  }
});

Is there a way to do this from the XML?

No, sorry. You can only specify the built-in typefaces through XML.

Is there a way to do it from code in one place, to say that the whole application and all the components should use the custom typeface instead of the default one?

Not that I am aware of.

There are a variety of options for these nowadays:

• Font resources and backports in the Android SDK, if you are using appcompat

• Third-party libraries for those not using appcompat, though not all will support defining the font in layout resources

1. There is no such thing as xhr.file = file;; the file object is not supposed to be attached this way.

2. xhr.send(file) doesn't send the file. You have to use the FormData object to wrap the file into a multipart/form-data post data object:

   var formData = new FormData();
   formData.append("thefile", file);
   xhr.send(formData);
   

After that, the file can be access in $_FILES['thefile'] (if you are using PHP).

Remember, MDC and Mozilla Hack demos are your best friends.

EDIT: The (2) above was incorrect. It does send the file, but it would send it as raw post data. That means you would have to parse it yourself on the server (and it's often not possible, depend on server configuration). Read how to get raw post data in PHP here.

I'd utilize the built in Date object to do the validation for me. Even after you switch from - to / you still need to check whether the month is between 0 and 12, the date is between 0 and 31 and the year between 1900 and 2013 for example.

function validateDOB(){

    var dob = document.forms["ProcessInfo"]["txtDOB"].value;
    var data = dob.split("/");
    // using ISO 8601 Date String
    if (isNaN(Date.parse(data[2] + "-" + data[1] + "-" + data[0]))) {
        return false;
    }

    return true;
}

See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/parse#Example:_Using_parse for more information.

Marc's answer is the approach I use for this, but for simplicity (and a friendlier API?) you can define a property in the collection base class if you have one such as:

public abstract class CollectionBase<T> : IList<T>
{
   ...

   public Type ElementType
   {
      get
      {
         return typeof(T);
      }
   }
}

I have found this approach useful, and is easy to understand for any newcomers to generics.

Define in wp_config file.

/var/www/html/Your-Project-File/wp-config.php

define( 'FS_METHOD', 'direct' );

chown - changes ownership of files/dirs. Ie. owner of the file/dir changes to the specified one, but it doesn't modify permissions.

sudo chown -R www-data:www-data /var/www

It's a little difficult to tell what you're trying to achieve, but assuming you're trying to get a Base64 string that when decoded is abcdef==, the following should work:

byte[] bytes = Encoding.UTF8.GetBytes("abcdef==");
string base64 = Convert.ToBase64String(bytes);
Console.WriteLine(base64);

This will output: YWJjZGVmPT0= which is abcdef== encoded in Base64.

Edit:

To decode a Base64 string, simply use Convert.FromBase64String(). E.g.

string base64 = "YWJjZGVmPT0=";
byte[] bytes = Convert.FromBase64String(base64);

At this point, bytes will be a byte[] (not a string). If we know that the byte array represents a string in UTF8, then it can be converted back to the string form using:

string str = Encoding.UTF8.GetString(bytes);
Console.WriteLine(str);

This will output the original input string, abcdef== in this case.

You're currently trying to access a method like a property

Console.WriteLine("{0}",x.fullNameMethod);

It should be

Console.WriteLine("{0}",x.fullNameMethod());

Alternatively you could turn it into a property using

public string fullName
{
   get
   {
        string x = firstName + " " + lastName;
        return x;
   }
}

You can use the standard Java SE APIs:

private void updateCustomer(Customer customer) { 
    try { 
        URL url = new URL("http://www.example.com/customers"); 
        HttpURLConnection connection = (HttpURLConnection) url.openConnection(); 
        connection.setDoOutput(true); 
        connection.setInstanceFollowRedirects(false); 
        connection.setRequestMethod("PUT"); 
        connection.setRequestProperty("Content-Type", "application/xml"); 

        OutputStream os = connection.getOutputStream(); 
        jaxbContext.createMarshaller().marshal(customer, os); 
        os.flush(); 

        connection.getResponseCode(); 
        connection.disconnect(); 
    } catch(Exception e) { 
        throw new RuntimeException(e); 
    } 
} 

Or you can use the REST client APIs provided by JAX-RS implementations such as Jersey. These APIs are easier to use, but require additional jars on your class path.

WebResource resource = client.resource("http://www.example.com/customers"); 
ClientResponse response = resource.type("application/xml");).put(ClientResponse.class, "<customer>...</customer."); 
System.out.println(response);

Below is the code that works well but my values overlap in sheet "Final" everytime the condition of <=11 meets in sheet "Calculator"

I would like you to kindly support me to modify the code so that the cursor should move to next blank cell and values keeps on adding up like a list.

Dim i As Integer
Dim ws1 As Worksheet: Set ws1 = ThisWorkbook.Sheets("Calculator")
Dim ws2 As Worksheet: Set ws2 = ThisWorkbook.Sheets("Final")

For i = 2 To ws1.Range("A65536").End(xlUp).Row

    If ws1.Cells(i, 4) <= 11 Then

        ws2.Cells(i, 1).Value = Left(Worksheets("Calculator").Cells(i, 1).Value, Len(Worksheets("Calculator").Cells(i, 1).Value) - 0)
        ws2.Cells(i, 2) = Application.VLookup(Cells(i, 1), Worksheets("Calculator").Columns("A:D"), 4, False)
        ws2.Cells(i, 3) = Application.VLookup(Cells(i, 1), Worksheets("Calculator").Columns("A:E"), 5, False)
        ws2.Cells(i, 4) = Application.VLookup(Cells(i, 1), Worksheets("Calculator").Columns("A:B"), 2, False)
        ws2.Cells(i, 5) = Application.VLookup(Cells(i, 1), Worksheets("Calculator").Columns("A:C"), 3, False)

    End If
Next i

Use word: using. A good habit of programming.

using (TcpClient tcpClient = new TcpClient())
{
     //operations
     tcpClient.Close();
}

I spent a lot of time on this issue and none of above solutions work for me. The names and number of build types were also exactly equal in both app and library project.

The only mistake I was making was - In library project's build.gradle, I was using line

apply plugin: 'com.android.application'

While this line should be -

apply plugin: 'com.android.library'

After making this change, this error got resolved.

if(!str.trim()){
  console.log('string is empty or only contains spaces');
}

Removing the whitespace from a string can be done using String#trim().

To check if a string is null or undefined, one can check if the string itself is falsey, in which case it is null, undefined, or an empty string. This first check is necessary, as attempting to invoke methods on null or undefined will result in an error. To check if it contains only spaces, one can check if the string is falsey after trimming, which means that it is an empty string at that point.

if(!str || !str.trim()){
   //str is null, undefined, or contains only spaces
}

This can be simplified using the optional chaining operator.

if(!str?.trim()){
   //str is null, undefined, or contains only spaces
}

If you are certain that the variable will be a string, only the second check is necessary.

if(!str.trim()){
   console.log("str is empty or contains only spaces");
}

found a way:

$albums = $facebook->api('/' . $user_id . '/albums');
foreach($albums['data'] as $album){
    if ($album['name'] == "Profile Pictures"){
        $photos = $facebook->api('/' . $album['id'] . '/photos');
        $profile_pic = $photos['data'][0]['source'];
        break;
    }
}

Using SQL Server 2012+, you can use the TRY_* functions if you have specific needs. For example,

-- will fail for decimal values, but allow negative values
TRY_CAST(@value AS INT) IS NOT NULL 

-- will fail for non-positive integers; can be used with other examples below as well, or reversed if only negative desired
TRY_CAST(@value AS INT) > 0

-- will fail if a $ is used, but allow decimals to the specified precision
TRY_CAST(@value AS DECIMAL(10,2)) IS NOT NULL 

-- will allow valid currency
TRY_CAST(@value AS MONEY) IS NOT NULL  

-- will allow scientific notation to be used like 1.7E+3
TRY_CAST(@value AS FLOAT) IS NOT NULL 

Given that you want a 100% client side solution, in theory you could probably do this:

Via XmlHttpRequest, get the directory listing page for that directory (most web servers return a listing of files if there is no index.html file in the directory).

Parse that file with javascript, pulling out all the .js files. This will of course be sensitive to the format of the directory listing on your web server / web host.

Add the script tags dynamically, with something like this:

function loadScript (dir, file) {
 var scr = document.createElement("script");
 scr.src = dir + file;
 document.body.appendChild(scr);
 }

I found that a lot all these answers use strings. I decided to change @HAS answer to use an enum:

If you already know what type it can cast to, use a C-style cast:

var o = (string) iKnowThisIsAString; 

Note that only with a C-style cast can you perform explicit type coercion.

If you don't know whether it's the desired type and you're going to use it if it is, use as keyword:

var s = o as string;
if (s != null) return s.Replace("_","-");

//or for early return:
if (s==null) return;

Note that as will not call any type conversion operators. It will only be non-null if the object is not null and natively of the specified type.

Use ToString() to get a human-readable string representation of any object, even if it can't cast to string.

I might understand the question incorrectly, but if you want to declare an array of a certain shape but with nothing inside, the following might be helpful:

Initialise empty array:

>>> a = np.zeros((0,3)) #or np.empty((0,3)) or np.array([]).reshape(0,3)
>>> a
array([], shape=(0, 3), dtype=float64)

Now you can use this array to append rows of similar shape to it. Remember that a numpy array is immutable, so a new array is created for each iteration:

>>> for i in range(3):
...     a = np.vstack([a, [i,i,i]])
...
>>> a
array([[ 0.,  0.,  0.],
       [ 1.,  1.,  1.],
       [ 2.,  2.,  2.]])

np.vstack and np.hstack is the most common method for combining numpy arrays, but coming from Matlab I prefer np.r_ and np.c_:

Concatenate 1d:

>>> a = np.zeros(0)
>>> for i in range(3):
...     a = np.r_[a, [i, i, i]]
...
>>> a
array([ 0.,  0.,  0.,  1.,  1.,  1.,  2.,  2.,  2.])

Concatenate rows:

>>> a = np.zeros((0,3))
>>> for i in range(3):
...     a = np.r_[a, [[i,i,i]]]
...
>>> a
array([[ 0.,  0.,  0.],
       [ 1.,  1.,  1.],
       [ 2.,  2.,  2.]])

Concatenate columns:

>>> a = np.zeros((3,0))
>>> for i in range(3):
...     a = np.c_[a, [[i],[i],[i]]]
...
>>> a
array([[ 0.,  1.,  2.],
       [ 0.,  1.,  2.],
       [ 0.,  1.,  2.]])

delete your local branch by following command

git branch -d branch_name

you could also do

git branch -D branch_name 

which basically force a delete (even if local not merged to source)

This methods might be convenient to use:

This method will return a random number between the provided min and max value:

public static int getRandomNumberBetween(int min, int max) {
    Random foo = new Random();
    int randomNumber = foo.nextInt(max - min) + min;
    if (randomNumber == min) {
        // Since the random number is between the min and max values, simply add 1
        return min + 1;
    } else {
        return randomNumber;
    }
}

and this method will return a random number from the provided min and max value (so the generated number could also be the min or max number):

public static int getRandomNumberFrom(int min, int max) {
    Random foo = new Random();
    int randomNumber = foo.nextInt((max + 1) - min) + min;

    return randomNumber;
}

Before Starting your Intent:

ActivityOptions options = ActivityOptions.makeSceneTransitionAnimation(AlbumListActivity.this);
startActivity(intent, options.toBundle());

This gives Default Animation to your Activity Transition.

If you are using jQuery 1.7:

alert($(this).prop("class"));

or:

alert($(event.target).prop("class"));

I found this problem continued even when setting the BODY MARGIN to zero.

However it turns out there is an easy fix. All you need to do is give your HEADER tag a 1px border, aswell as setting the BODY MARGIN to zero, as shown below.

body { margin:0px; }

header { border:1px black solid; }

If you have any H1, H2, tags within your HEADER you will also need to set the MARGIN for these tags to zero, this will get rid of any extra space which may show up.

Not sure why this works, but I use Chrome browser. Obviously you can also change the colour of the border to match your header colour.

You cannot really find the display resolution from a web page. There is a CSS Media Queries statement for it, but it is poorly implemented in most devices and browsers, if at all. However, you do not need to know the resolution of the display, because changing it causes the (pixel) width of the window to change, which can be detected using the methods others have described:

$(window).resize(function() {
  // This will execute whenever the window is resized
  $(window).height(); // New height
  $(window).width(); // New width
});

You can also use CSS Media Queries in browsers that support them to adapt your page's style to various display widths, but you should really be using em units and percentages and min-width and max-width in your CSS if you want a proper flexible layout. Gmail probably uses a combination of all these.

Guava offers Lists#reverse(List) and ImmutableList#reverse(). As in most cases for Guava, the former delegates to the latter if the argument is an ImmutableList, so you can use the former in all cases. These do not create new copies of the list but just "reversed views" of it.

Example

List reversed = ImmutableList.copyOf(myList).reverse();

Use the AddWithValue method:

comm.Parameters.AddWithValue("@person", "Myname");
comm.Parameters.AddWithValue("@address", "Myaddress");

Have you considered installing MacPorts 1.8.0 (release candidate), and keeping MySQL up-to-date that way? That will build MySQL for the architecture and OS that you're using, rather than installing a 10.5 version on 10.6.

Try this code, I got it from here

$input = Array(1,2,3,1,2,3,4,5,6);
$input = array_map("unserialize", array_unique(array_map("serialize", $input)));

def function(a):
    if a == '1':
        print ('1a')
    else if a == '2'
        print ('2a')
    else print ('3a')

Should be corrected to:

def function(a):
    if a == '1':
        print('1a')
    elif a == '2':
        print('2a')
    else:
        print('3a')

As you can see, else if should be changed to elif, there should be colons after '2' and else, there should be a new line after the else statement, and close the space between print and the parentheses.

You could use the Fisher-Yates Shuffle (code adapted from this site):

function shuffle(array) {
    let counter = array.length;

    // While there are elements in the array
    while (counter > 0) {
        // Pick a random index
        let index = Math.floor(Math.random() * counter);

        // Decrease counter by 1
        counter--;

        // And swap the last element with it
        let temp = array[counter];
        array[counter] = array[index];
        array[index] = temp;
    }

    return array;
}

You can use following procedure by passing mac address for validation,

private static final String MAC_PATTERN = "^([0-9A-Fa-f]{2}[:-]){5}([0-9A-Fa-f]{2})$";

private boolean validateMAC(final String mac){          
    Pattern pattern = Pattern.compile(MAC_PATTERN);
    Matcher matcher = pattern.matcher(mac);
    return matcher.matches();             
}

Someone else recommended "M-x shell RET" in Emacs. I think "M-x eshell RET" is even better.

Since using the @Value("new Long("myconfig")") with cast could throw error on startup if the config is not found or if not in the same expected number format

We used the following approach and is working as expected with fail safe check.

@Configuration()
public class MyConfiguration {

   Long DEFAULT_MAX_IDLE_TIMEOUT = 5l;

   @Value("db.timeoutInString")
   private String timeout;

   public Long getTimout() {
        final Long timoutVal = StringUtil.parseLong(timeout);
        if (null == timoutVal) {
            return DEFAULT_MAX_IDLE_TIMEOUT;
        }
        return timoutVal;
    }
}
   

The slider object contains the slide count as property.

Slick < 1.5

$('.slideshow').slick({
    slide: 'img',
    autoplay: true,
    dots: true,
    dotsClass: 'custom_paging',
    customPaging: function (slider, i) {
        //FYI just have a look at the object to find available information
        //press f12 to access the console in most browsers
        //you could also debug or look in the source
        console.log(slider);
        return  (i + 1) + '/' + slider.slideCount;
    }
});

Update for Slick 1.5+ (tested until 1.8.1)

var $status = $('.pagingInfo');
var $slickElement = $('.slideshow');

$slickElement.on('init reInit afterChange', function(event, slick, currentSlide, nextSlide){
    //currentSlide is undefined on init -- set it to 0 in this case (currentSlide is 0 based)
    var i = (currentSlide ? currentSlide : 0) + 1;
    $status.text(i + '/' + slick.slideCount);

Tom if you have existing array you can convert that array to object and use it like this:

$r = (object) $MyQueryResult;
echo $r->key;

call() It’s a predefined method in javascript. This method invokes a method (function) by specifying the owner object.

  function sayHello(){
  return "Hello " + this.name;
}
        
var obj = {name: "Sandy"};
        
sayHello.call(obj);
        
// Returns "Hello Sandy"

Call accepts argument

function saySomething(message){
  return this.name + " is " + message;
}
        
var person4 = {name:  "John"};
        
saySomething.call(person4, "awesome");
// Returns "John is awesome"    

apply() The apply method is similar to the call() method. The only difference is that, call() method takes arguments separately whereas, apply() method takes arguments as an array.

example

function saySomething(message){
  return this.name + " is " + message;
}
        
var person4 = {name:  "John"};
        
saySomething.apply(person4, ["awesome"]);

For texts in utf-8, it worked for me mb_convert_encoding. To process everything regardless of errors, make sure you use the "@".

The basic code I use is:

$dom = new DOMDocument();
@$dom->loadHTML(mb_convert_encoding($html, 'HTML-ENTITIES', 'UTF-8'));

$body = $dom->getElementsByTagName('body')->item(0);
echo $body->textContent;

If you want something more advanced, you can iteratively analyze the nodes, but you will encounter many problems with whitespaces.

I have implemented a converter based on what I say here. If you are interested, you can download it from git https://github.com/kranemora/html2text

It may serve as a reference to make yours

You can use it like this:

$html = <<<EOF
<p>Welcome to <strong>html2text<strong></p>
<p>It's <em>works</em> for you?</p>
EOF;

$html2Text = new \kranemora\Html2Text\Html2Text;
$text = $html2Text->convert($html);

A unit test tests code that you have complete control over whereas an integration test tests how your code uses or "integrates" with some other code.

So you would write unit tests to make sure your own libraries work as intended, and then write integration tests to make sure your code plays nicely with other code you are making use of, for instance a library.

Functional tests are related to integration tests, but refer more specifically to tests that test an entire system or application with all of the code running together, almost a super integration test.

use this tag {!! description text !!}

You can use this jQuery code which I find it eaiser to use:

$('#your_id [value=3]').attr('selected', 'true');

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
_x000D_
<select id="your_id" name="name" class="form-control input-md">_x000D_
  <option value="1">Option #1</option>_x000D_
  <option value="2">Option #2</option>_x000D_
  <option value="3">Option #3</option>_x000D_
  <option value="4">Option #4</option>_x000D_
  <option value="5">Option #5</option>_x000D_
  <option value="6">Option #6</option>_x000D_
  <option value="7">Option #7</option>_x000D_
</select>

for LocalBroadcastManager

   Intent intent = new Intent("any.action.string");
   LocalBroadcastManager.getInstance(context).
                                sendBroadcast(intent);

and register in onResume

LocalBroadcastManager.getInstance(
                    ActivityName.this).registerReceiver(chatCountBroadcastReceiver, filter);

and Unregister it onStop

LocalBroadcastManager.getInstance(
                ActivityName.this).unregisterReceiver(chatCountBroadcastReceiver);

and recieve it ..

mBroadcastReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            Log.e("mBroadcastReceiver", "onReceive");
        }
    };

where IntentFilter is

 new IntentFilter("any.action.string")

You can't as most of the posts are explaining, let me add another area:

On many websites you will find people saying that the way to avoid this is using a different AppDomain so if this happens the domain will be unloaded. That is absolutely wrong (unless you host your CLR) as the default behavior of the CLR will raise a KillProcess event, bringing down your default AppDomain.

You can use navigator.mimeTypes.

if (navigator.mimeTypes ["application/x-shockwave-flash"] == undefined)
    $("#someDiv").show ();

By using the SqlCommand and its child collection of parameters all the pain of checking for sql injection is taken away from you and will be handled by these classes.

Here is an example, taken from one of the articles above:

private static void UpdateDemographics(Int32 customerID,
    string demoXml, string connectionString)
{
    // Update the demographics for a store, which is stored  
    // in an xml column.  
    string commandText = "UPDATE Sales.Store SET Demographics = @demographics "
        + "WHERE CustomerID = @ID;";

    using (SqlConnection connection = new SqlConnection(connectionString))
    {
        SqlCommand command = new SqlCommand(commandText, connection);
        command.Parameters.Add("@ID", SqlDbType.Int);
        command.Parameters["@ID"].Value = customerID;

        // Use AddWithValue to assign Demographics. 
        // SQL Server will implicitly convert strings into XML.
        command.Parameters.AddWithValue("@demographics", demoXml);

        try
        {
            connection.Open();
            Int32 rowsAffected = command.ExecuteNonQuery();
            Console.WriteLine("RowsAffected: {0}", rowsAffected);
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        }
    }
}

If you want to get current directory path within a file for that you can magic constants __FILE__ and __DIR__ with plugin_dir_path() function as:

$dir_path = plugin_dir_path( __FILE__ );

CurrentDirectory Path:

/home/user/var/www/wordpress_site/wp-content/plugins/custom-plugin/

__FILE__ magic constant returns current directory path.

If you want to one level up from the current directory. You should use __DIR__ magic constant as:

Current Path:

/home/user/var/www/wordpress_site/wp-content/plugins/custom-plugin/

$dir = plugin_dir_path( __DIR__ );

One level up path:

 /home/user/var/www/wordpress_site/wp-content/plugins/

__DIR__ magic constant returns one level up directory path.

here's another one:

Drawable drawable = RoundedBitmapDrawableFactory.create(context.getResources(), bitmap);

To prove There's More Than One Six Ways To Do It:

plus_1 = 1.method(:+)
Array.new(3, &plus_1) # => [1, 2, 3]

If 1.method(:+) wasn't possible, you could also do

plus_1 = Proc.new {|n| n + 1}
Array.new(3, &plus_1) # => [1, 2, 3]

Sure, it's overkill in this scenario, but if plus_1 was a really long expression, you might want to put it on a separate line from the array creation.

I would recommend Toad data modeller

Login into your server using a shell program like putty.

Type in the following command on the command line

zcat DB_File_Name.sql.gz | mysql -u username -p Target_DB_Name

where

DB_File_Name.sql.gz = full path of the sql.gz file to be imported

username = your mysql username

Target_DB_Name = database name where you want to import the database

When you hit enter in the command line, it will prompt for password. Enter your MySQL password.

You are done!

If your xml is written by java.lang.String you can just using HttpClient in this way

    public void post() throws Exception{
        HttpClient client = new DefaultHttpClient();
        HttpPost post = new HttpPost("http://www.baidu.com");
        String xml = "<xml>xxxx</xml>";
        HttpEntity entity = new ByteArrayEntity(xml.getBytes("UTF-8"));
        post.setEntity(entity);
        HttpResponse response = client.execute(post);
        String result = EntityUtils.toString(response.getEntity());
    }

pay attention to the Exceptions.

BTW, the example is written by the httpclient version 4.x

First off I should point out that css animations would probably work best if you are doing this a lot but I ended getting the desired effect by wrapping .scrollLeft inside .animate

$('.swipeRight').click(function()
{

    $('.swipeBox').animate( { scrollLeft: '+=460' }, 1000);
});

$('.swipeLeft').click(function()
{
    $('.swipeBox').animate( { scrollLeft: '-=460' }, 1000);
});

The second parameter is speed, and you can also add a third parameter if you are using smooth scrolling of some sort.

Update! New & improved! Find plugin @ GitHub!

On another note, while that method is simple, I've created a jQuery plug (found at this jsFiddle, just copy and past code between comment lines) that makes changing the cursor on any element as simple as $("element").cursor("pointer").

But that's not all! Act now and you'll get the hand functions position & ishover for no extra charge! That's right, 2 very handy cursor functions ... FREE!

They work as simple as seen in the demo:

$("h3").cursor("isHover"); // if hovering over an h3 element, will return true, 
    // else false
// also handy as
$("h2, h3").cursor("isHover"); // unless your h3 is inside an h2, this will be 
    // false as it checks to see if cursor is hovered over both elements, not just the last!
//  And to make this deal even sweeter - use the following to get a jQuery object
//       of ALL elements the cursor is currently hovered over on demand!
$.cursor("isHover");

Also:

$.cursor("position"); // will return the current cursor position as { x: i, y: i }
    // at anytime you call it!

Supplies are limited, so Act Now!

You can directly use the style histograms provide by gnuplot. This is an example if you have two file in output:

set style data histograms
 set style fill solid
 set boxwidth 0.5
 plot "file1.dat" using 5 title "Total1" lt rgb "#406090",\
      "file2.dat" using 5 title "Total2" lt rgb "#40FF00"

git rev-parse Also works for getting the current branch name using the --abbrev-ref flag like:

git rev-parse --abbrev-ref HEAD

You can run a script, or a more complex parameter to the RUN. Here is an example from a Dockerfile I've downloaded to look at previously:

RUN cd /opt && unzip treeio.zip && mv treeio-master treeio && \
    rm -f treeio.zip && cd treeio && pip install -r requirements.pip

Because of the use of '&&', it will only get to the final 'pip install' command if all the previous commands have succeeded.

In fact, since every RUN creates a new commit & (currently) an AUFS layer, if you have too many commands in the Dockerfile, you will use up the limits, so merging the RUNs (when the file is stable) can be a very useful thing to do.

<ItemTemplate>
     <asp:Button ID="Button1" runat="server" Text="Button" 
            OnClick="MyButtonClick" />
</ItemTemplate>

and your method

 protected void MyButtonClick(object sender, System.EventArgs e)
{
     //Get the button that raised the event
Button btn = (Button)sender;

    //Get the row that contains this button
GridViewRow gvr = (GridViewRow)btn.NamingContainer;
}

Douglas Crockford, the author of jslint has written (and spoken) about this issue many times. There's a section on this page of his website which covers this:

for Statement

A for class of statements should have the following form:

for (initialization; condition; update) {
    statements
}

for (variable in object) {
    if (filter) {
        statements
    } 
}

The first form should be used with arrays and with loops of a predeterminable number of iterations.

The second form should be used with objects. Be aware that members that are added to the prototype of the object will be included in the enumeration. It is wise to program defensively by using the hasOwnProperty method to distinguish the true members of the object:

for (variable in object) {
    if (object.hasOwnProperty(variable)) {
        statements
    } 
}

Crockford also has a video series on YUI theater where he talks about this. Crockford's series of videos/talks about javascript are a must see if you're even slightly serious about javascript.

I encountered the error while migrating an app from Ruby 1.8.7 to 1.9.3 and it only occured in production. It turned out that I had some leftovers in my Memcache store. The now encoding sensitive Ruby 1.9.3 version of my app tried to mix old ASCII-8BIT values with new UTF-8.

It was as simple as flushing the cache to fix it for me.

UPDATED :

check this answer may this help you

if ((Request.Headers["XYZComponent"] ?? "") == "true")

    // header is present and set to "true"
}

Or to swap the output from standard error and standard output over, use:

command 3>&1 1>&2 2>&3

This creates a new file descriptor (3) and assigns it to the same place as 1 (standard output), then assigns fd 1 (standard output) to the same place as fd 2 (standard error) and finally assigns fd 2 (standard error) to the same place as fd 3 (standard output).

Standard error is now available as standard output and the old standard output is preserved in standard error. This may be overkill, but it hopefully gives more details on Bash file descriptors (there are nine available to each process).

An API is ready-made source code library.

In Java for example APIs are a set of related classes and interfaces that come in packages. This picture illustrates the libraries included in the Java Standard Edition API. Packages are denoted by their color.

   volumes: 
     pgdata:

It will create volume name pgdata and mount this volume to container's path.

You can inspect this volume

docker volume inspect pgdata

// output will be
[
    {
        "Driver": "local",
        "Labels": {},
        "Mountpoint": "/var/lib/docker/volumes/pgdata/_data",
        "Name": "pgdata",
        "Options": {},
        "Scope": "local"
    }
]

You can try this... put parameters as :
http://localhost:8080/WebApplication11/webresources/generic/getText?arg1=hello in your browser...

package newpackage;

You should use Jérôme Petazzoni's tool called 'nsenter' to enter a container without using SSH. See: https://github.com/jpetazzo/nsenter

Install with simply running: docker run -v /usr/local/bin:/target jpetazzo/nsenter

Then use the command docker-enter <container-id> to enter the container.

use this URL : "https://twitter.com/(userName)/profile_image?size=original"

If you are using TWitter SDK you can get the user name when logged in, with TWTRAPIClient, using TWTRAuthSession.

This is the code snipe for iOS:

if let twitterId = session.userID{
   let twitterClient = TWTRAPIClient(userID: twitterId)
   twitterClient.loadUser(withID: twitterId) {(user, error) in
       if let userName = user?.screenName{
          let url = "https://twitter.com/\(userName)/profile_image?size=original")
       }
   }
}

Use this

@Table (name = "Test", schema = "\"schema\"")

insteade of @Table (name = "Test", schema = "schema")

If you are on postgresql the request is :

SELECT * FROM "schema".test 

not :

SELECT * FROM schema.test

PS: Test is a table

SELECT group,subGroup,COUNT(*) FROM tablename GROUP BY group,subgroup

Update: To create a popup menu in android with Kotlin refer my answer here.

To create a popup menu in android with Java:

Create a layout file activity_main.xml under res/layout directory which contains only one button.

Filename: activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"  
    xmlns:tools="http://schemas.android.com/tools"  
    android:layout_width="match_parent"  
    android:layout_height="match_parent"  
    android:paddingBottom="@dimen/activity_vertical_margin"  
    android:paddingLeft="@dimen/activity_horizontal_margin"  
    android:paddingRight="@dimen/activity_horizontal_margin"  
    android:paddingTop="@dimen/activity_vertical_margin"  
    tools:context=".MainActivity" >  

    <Button  
        android:id="@+id/button1"  
        android:layout_width="wrap_content"  
        android:layout_height="wrap_content"  
        android:layout_alignParentLeft="true"  
        android:layout_alignParentTop="true"  
        android:layout_marginLeft="62dp"  
        android:layout_marginTop="50dp"  
        android:text="Show Popup" />  

</RelativeLayout>  

Create a file popup_menu.xml under res/menu directory

It contains three items as shown below.

Filename: poupup_menu.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android" >  

    <item  
        android:id="@+id/one"  
        android:title="One"/>  

    <item  
        android:id="@+id/two"  
        android:title="Two"/>  

    <item  
        android:id="@+id/three"  
        android:title="Three"/>  

</menu>  

MainActivity class which displays the popup menu on button click.

Filename: MainActivity.java

public class MainActivity extends Activity {  
    private Button button1;  

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

        button1 = (Button) findViewById(R.id.button1);
        button1.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                //Creating the instance of PopupMenu
                PopupMenu popup = new PopupMenu(MainActivity.this, button1);
                //Inflating the Popup using xml file
                popup.getMenuInflater()
                    .inflate(R.menu.popup_menu, popup.getMenu());

                //registering popup with OnMenuItemClickListener
                popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
                    public boolean onMenuItemClick(MenuItem item) {
                        Toast.makeText(
                            MainActivity.this,
                            "You Clicked : " + item.getTitle(),
                            Toast.LENGTH_SHORT
                        ).show();
                        return true;
                    }
                });

                popup.show(); //showing popup menu
            }
        }); //closing the setOnClickListener method
    }
}

To add programmatically:

PopupMenu menu = new PopupMenu(this, view);

menu.getMenu().add("One");
menu.getMenu().add("Two");
menu.getMenu().add("Three");

menu.show();

Follow this link for creating menu programmatically.

I also run into this problem when I wanted to upgrade system pip pip3 from 9.0.1 to 19.2.3.

After running pip3 install --upgrade pip, pip version becomes 19.2.3. But main() has been moved in pip._internal in the latest version, which leaves pip3 broken.

So in file /usr/bin/pip3, replace line 9: from pip import main with from pip._internal import main. The issue will be fixed, works the same for python2-pip. (Tested on Ubuntu 18.04 distribution)

According to @Vincent H.'s answer

Either escape the double quotes with \

String xmlString = "<element attribname=\"value\" attribname1=\"value1\"> pcdata</element>"

or use single quotes instead

String xmlString = "<element attribname='value' attribname1='value1'> pcdata</element>"

From axios docs you have baseURL and url

baseURL will be prepended to url when making requests. So you can define baseURL as http://127.0.0.1:8000 and make your requests to /url

 // `url` is the server URL that will be used for the request
 url: '/user',

 // `baseURL` will be prepended to `url` unless `url` is absolute.
 // It can be convenient to set `baseURL` for an instance of axios to pass relative URLs
 // to methods of that instance.
 baseURL: 'https://some-domain.com/api/',

Here's a benchmark to compare a Go for statement with a ForClause and a Go range statement using the iter package.

iter_test.go

package main

import (
    "testing"

    "github.com/bradfitz/iter"
)

const loops = 1e6

func BenchmarkForClause(b *testing.B) {
    b.ReportAllocs()
    j := 0
    for i := 0; i < b.N; i++ {
        for j = 0; j < loops; j++ {
            j = j
        }
    }
    _ = j
}

func BenchmarkRangeIter(b *testing.B) {
    b.ReportAllocs()
    j := 0
    for i := 0; i < b.N; i++ {
        for j = range iter.N(loops) {
            j = j
        }
    }
    _ = j
}

// It does not cause any allocations.
func N(n int) []struct{} {
    return make([]struct{}, n)
}

func BenchmarkIterAllocs(b *testing.B) {
    b.ReportAllocs()
    var n []struct{}
    for i := 0; i < b.N; i++ {
        n = iter.N(loops)
    }
    _ = n
}

Output:

$ go test -bench=. -run=.
testing: warning: no tests to run
PASS
BenchmarkForClause      2000       1260356 ns/op           0 B/op          0 allocs/op

$

Sure you can. Something like:

HTML

<div ng-controller="fessCntrl">    
     <label ng-repeat="(key,val) in list">
       <input type="radio" name="localityTypeRadio" ng-model="$parent.localityTypeRadio" ng-value="key" />{{key}}
         <div ng-if="key == 'City' || key == 'County'">
             <pre>City or County !!! {{$parent.localityTypeRadio}}</pre>
         </div>
         <div ng-if="key == 'Town'">
             <pre>Town!!! {{$parent.localityTypeRadio}}</pre>
         </div>        
      </label>
</div>

JS

var fessmodule = angular.module('myModule', []);

fessmodule.controller('fessCntrl', function ($scope) {

    $scope.list = {
        City: [{name: "cityA"}, {name: "cityB"}],
        County: [{ name: "countyA"}, {name: "countyB"}],
        Town: [{ name: "townA"}, {name: "townB"}]
      };

    $scope.localityTypeRadio = 'City';
});

fessmodule.$inject = ['$scope'];

Demo Fiddle

Sometimes JavaScript is not activated. Try something like:

<!DOCTYPE html>
<html>
  <head>

    <script type="text/javascript"> <!--
      function jActivator() {
        document.getElementById("demo").onclick = function() {myFunction()};
        document.getElementById("demo1").addEventListener("click", myFunction);
        }
      function myFunction( s ) {
        document.getElementById("myresult").innerHTML = s;
        }
    // --> </script>
    <noscript>JavaScript deactivated.</noscript>
    <style type="text/css">
    </style>
  </head>
  <body onload="jActivator()">
    <ul>
      <li id="demo">Click me -&gt; onclick.</li>
      <li id="demo1">Click me -&gt; click event.</li>
      <li onclick="myFunction('YOU CLICKED ME!')">Click me calling function.</li>
    </ul>
    <div id="myresult">&nbsp;</div>
  </body>
</html>

If you use the code inside a page, where no access to is possible, remove and tags and try to use 'onload=()' in a picture inside the image tag '

Use listboxControl.Column(intColumn,intRow). Both Column and Row are zero-based.

Turn the string into a list; then you can change the characters individually. Then you can put it back together with .join:

s = 'a;b;c;d'
slist = list(s)
for i, c in enumerate(slist):
    if slist[i] == ';' and 0 <= i <= 3: # only replaces semicolons in the first part of the text
        slist[i] = ':'
s = ''.join(slist)
print s # prints a:b:c;d

Thanks Shuwaiee

I made a slight change though as using it in a Private Sub already.

Dim GetIPAddress()

Dim strHostName As String

Dim strIPAddress As String

strHostName = System.Net.Dns.GetHostName()

strIPAddress = System.Net.Dns.GetHostByName(strHostName).AddressList(0).ToString()

MessageBox.Show("Host Name: " & strHostName & vbCrLf & "IP Address: " & strIPAddress)

But also made a change to the way the details are displayed so that they can show on seperate lines using & vbCrLf &

MessageBox.Show("Host Name: " & strHostName & vbCrLf & "IP Address: " & strIPAddress)

Hope this helps someone.

In gitk --all:

• right click on the commit you want
• -> create new branch
• enter the name of an existing branch
• press return on the dialog that confirms replacing the old branch of that name.

Beware that re-creating instead of modifying the existing branch will lose tracking-branch information. (This is generally not a problem for simple use-cases where there's only one remote and your local branch has the same name as the corresponding branch in the remote. See comments for more details, thanks @mbdevpl for pointing out this downside.)

It would be cool if gitk had a feature where the dialog box had 3 options: overwrite, modify existing, or cancel.

Even if you're normally a command-line junkie like myself, git gui and gitk are quite nicely designed for the subset of git usage they allow. I highly recommend using them for what they're good at (i.e. selectively staging hunks into/out of the index in git gui, and also just committing. (ctrl-s to add a signed-off: line, ctrl-enter to commit.)

gitk is great for keeping track of a few branches while you sort out your changes into a nice patch series to submit upstream, or anything else where you need to keep track of what you're in the middle of with multiple branches.

I don't even have a graphical file browser open, but I love gitk/git gui.

C++11 has some portable timer stuff. Check out sleep_for.

If you use the url attribute, just do

table.ajax.reload()

I use Object.keys which is built into JavaScript Object, it will return an array of keys from given object MDN Reference

var obj = {name: "Jeeva", age: "22", gender: "Male"}
console.log(Object.keys(obj))

To others not using RubyMotion and don't think that deleting the app is acceptable (as in, you want to do upgrade testing). Check out the bottom of these docs from Apple:

https://developer.apple.com/library/ios/technotes/tn2319/_index.html

It looks like they changed something in 8.1.3 to check for this new rule.

The Fix

"[Add] the installed application’s application-identifier value, as logged in the second parentheses, to the previous-application-identifiers entitlement’s array value for the app being installed (by resigning it or re-building it) and requesting new special provisioning profiles as shown below."

<key>previous-application-identifiers</key>
<array>
    <string>{Your Old App ID Prefix}.YourApp.Bundle.ID</string>
</array>

EDIT:

In order to do this, you need special provisioning profiles. You can request these from Apple: "To enable signing with the previous-application-identifiers entitlement new special provisioning profiles are required that can be obtained by going to the Contact US page and requesting them." (from the docs linked above).

Your route isn't ok, it should be like this (with ':')

app.get('/documents/:format/:type', function (req, res) {
   var format = req.params.format,
       type = req.params.type;
});

Also you cannot interchange parameter order unfortunately. For more information on req.params (and req.query) check out the api reference here.

If you use the OOP method of inserting, you don't need to worry about mass-action/fillable properties:

$user = new User;
$user->username = 'Stevo';
$user->email = '[email protected]';
$user->password = '45678';
$user->save();
