Programs & Examples On #Custom font

If other answers didn't work try:

1. check .htaccess file

   # Fonts
# Add correct content-type for fonts
   

   AddType application/vnd.ms-fontobject .eot
AddType application/x-font-ttf .ttf
AddType application/x-font-opentype .otf
AddType application/x-font-woff .woff
AddType application/x-font-woff2 .woff2
AddType image/svg+xml .svg
   

2. clear server cache

3. clear browser cache & reload

The best way to do it From Android O preview release is this way:

It works only if you have android studio-2.4 or above

1. Right-click the res folder and go to New > Android resource directory. The New
   Resource Directory window appears.
   
2. In the Resource type list, select font, and then click OK.
   
3. Add your font files in the font folder.The folder structure below generates R.font.dancing_script, R.font.la_la, and R.font.ba_ba.
   
4. Double-click a font file to preview the file's fonts in the editor.

Next we must create a font family:

1. Right-click the font folder and go to New > Font resource file. The New Resource File window appears.
   
2. Enter the File Name, and then click OK. The new font resource XML opens in the editor.
   

3. Enclose each font file, style, and weight attribute in the font tag element. The following XML illustrates adding font-related attributes in the font resource XML:

Adding fonts to a TextView:

   <TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:fontFamily="@font/hey_fontfamily"/>

As from the documentation

Working With Fonts

All the steps are correct.

create a new class called ComboKeyValue.java

    public class ComboKeyValue {
        private String key;
        private String value;
    
        public ComboKeyValue(String key, String value) {
            this.key = key;
            this.value = value;
        }
        
        @Override
        public String toString(){
            return key;
        }
    
        public String getKey() {
            return key;
        }
    
        public String getValue() {
            return value;
        }
}

when you want to add a new item, just write the code as below

 DefaultComboBoxModel model = new DefaultComboBoxModel();
    model.addElement(new ComboKeyValue("key", "value"));
    properties.setModel(model);

The function you're looking for is 'Insert'. It takes as its parameters the index you want to insert at, and an array of values to use for the new row values. Typical usage might include:

myDataGridView.Rows.Insert(4,new object[]{value1,value2,value3});

or something to that effect.

I run mine through my (BASH GIT) console also running Entity Framework Core. Update-Database commands will not work outside of the package console and I have to use the donet ef commands.

donet ef database update [Name of previous Migration]

This will run the protected override void Down(MigrationBuilder migrationBuilder) method of your current migration and all of the others to get back to the version of the DB you set it to.

I also use the -p [migration project] -s [Project Solution]. This also allows it to point to my appsettings.[Enviorment].json where my password to access DB is stored.

export ASPNETCORE_ENVIRONMENT=[ENVIORMENT]; donet ef database update [Name of previous Migration] -p [Migration Project Name] -s [Solution Name]

A lot of this might be known but wanted to give detail in case your first time doing.

If you are looking for a way to import all your images from the image

// Import all images in image folder
function importAll(r) {
    let images = {};
    r.keys().map((item, index) => { images[item.replace('./', '')] = r(item); });
    return images;
}

const images = importAll(require.context('../images', false, /\.(gif|jpe?g|svg)$/));

Then:

<img src={images['image-01.jpg']}/>

You can find the original thread here: Dynamically import images from a directory using webpack

Be careful with Backslashes, don't forget them (neither use twice:)

string relativePath = "..\\bling.txt";
string baseDirectory = "C:\\blah\\";
//OR:
//string relativePath = "\\..\\bling.txt";
//string baseDirectory = "C:\\blah";
//THEN
string absolutePath = Path.GetFullPath(baseDirectory + relativePath);

First off, your quoted code is not JSON. Your code is JavaScript object literal notation. JSON is a subset of that designed for easier parsing.

Your code defines an object (data) containing an array (items) of objects (each with an id, name, and type).

You don't need or want jQuery for this, just JavaScript.

Adding an item:

data.items.push(
    {id: "7", name: "Douglas Adams", type: "comedy"}
);

That adds to the end. See below for adding in the middle.

Removing an item:

There are several ways. The splice method is the most versatile:

data.items.splice(1, 3); // Removes three items starting with the 2nd,
                         // ("Witches of Eastwick", "X-Men", "Ordinary People")

splice modifies the original array, and returns an array of the items you removed.

Adding in the middle:

splice actually does both adding and removing. The signature of the splice method is:

removed_items = arrayObject.splice(index, num_to_remove[, add1[, add2[, ...]]]);

• index - the index at which to start making changes
• num_to_remove - starting with that index, remove this many entries
• addN - ...and then insert these elements

So I can add an item in the 3rd position like this:

data.items.splice(2, 0,
    {id: "7", name: "Douglas Adams", type: "comedy"}
);

What that says is: Starting at index 2, remove zero items, and then insert this following item. The result looks like this:

var data = {items: [
    {id: "1", name: "Snatch", type: "crime"},
    {id: "2", name: "Witches of Eastwick", type: "comedy"},
    {id: "7", name: "Douglas Adams", type: "comedy"},     // <== The new item
    {id: "3", name: "X-Men", type: "action"},
    {id: "4", name: "Ordinary People", type: "drama"},
    {id: "5", name: "Billy Elliot", type: "drama"},
    {id: "6", name: "Toy Story", type: "children"}
]};

You can remove some and add some at once:

data.items.splice(1, 3,
    {id: "7", name: "Douglas Adams", type: "comedy"},
    {id: "8", name: "Dick Francis", type: "mystery"}
);

...which means: Starting at index 1, remove three entries, then add these two entries. Which results in:

var data = {items: [
    {id: "1", name: "Snatch", type: "crime"},
    {id: "7", name: "Douglas Adams", type: "comedy"},
    {id: "8", name: "Dick Francis", type: "mystery"},
    {id: "4", name: "Ordinary People", type: "drama"},
    {id: "5", name: "Billy Elliot", type: "drama"},
    {id: "6", name: "Toy Story", type: "children"}
]};

Try this regex:

/^[a-z\d\-_\s]+$/i

I needed to do the same thing, so have written some JavaScript to enable this, using the onSelect and beforeShowDay events. It maintains its own array of selected dates, so unfortunately doesn't integrate with a textbox showing the current date, etc. I'm just using it as an inline control, and I can then query the array for the currently selected dates.
I used this code as a basis.

<script type="text/javascript">
// Maintain array of dates
var dates = new Array();

function addDate(date) {
    if (jQuery.inArray(date, dates) < 0) 
        dates.push(date);
}

function removeDate(index) {
    dates.splice(index, 1);
}

// Adds a date if we don't have it yet, else remove it
function addOrRemoveDate(date) {
    var index = jQuery.inArray(date, dates);
    if (index >= 0) 
        removeDate(index);
    else 
        addDate(date);
}

// Takes a 1-digit number and inserts a zero before it
function padNumber(number) {
    var ret = new String(number);
    if (ret.length == 1) 
        ret = "0" + ret;
    return ret;
}

jQuery(function () {
    jQuery("#datepicker").datepicker({
        onSelect: function (dateText, inst) {
            addOrRemoveDate(dateText);
        },
        beforeShowDay: function (date) {
            var year = date.getFullYear();
            // months and days are inserted into the array in the form, e.g "01/01/2009", but here the format is "1/1/2009"
            var month = padNumber(date.getMonth() + 1);
            var day = padNumber(date.getDate());
            // This depends on the datepicker's date format
            var dateString = month + "/" + day + "/" + year;

            var gotDate = jQuery.inArray(dateString, dates);
            if (gotDate >= 0) {
                // Enable date so it can be deselected. Set style to be highlighted
                return [true, "ui-state-highlight"];
            }
            // Dates not in the array are left enabled, but with no extra style
            return [true, ""];
        }
    });
});
</script>

I like to simplify the code without using conditional operators in such cases:

TEMP=/mnt/silo/bin
[[ ${PATH} =~ ${TEMP} ]] || PATH=$PATH:$TEMP

I have tested this on Manjaro Linux. Should work on other Disto too.

You need to include whole java-jdk dir instead of just java/bin for java env var.

For example, instead of:

export JAVA_HOME=/opt/jdk-14.0.2/bin #change path according to your jdk location PATH=$PATH:$JAVA_HOME

use this:

export JAVA_HOME=/opt/jdk-14.0.2/ #change path according to your jdk location PATH=$PATH:$JAVA_HOME

then run the gradle command it will work.

Checking Google's example Source Code I found out how to make the toolbar completely transparent. It was simpler than I thought. We just have to create a simple Shape drawable like this.

The name of the drawable is toolbar_bg

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
<gradient
    android:angle="90"
    android:startColor="@android:color/transparent"
    android:endColor="@android:color/transparent"
    android:type="linear" />
</shape>

And then in the fragment or activity.. Add the toolbar like this.

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:layout_alignParentStart="true"
        android:layout_alignParentTop="true"
        android:background="@drawable/toolbar_bg"
        android:popupTheme="@style/ThemeOverlay.AppCompat.Light"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"/>

And here we will have a fully transparent toolbar.

Don't add the <android.support.design.widget.AppBarLayout > if you do, this won't work.

Note: If you need the AppBarLayout, set the elevation to 0 so it doesn't draw its shadow.

You can use the backslash to include both the story and the players name in one line.

var name=prompt("what is your name?"); console.log("story"\name\"story");

Windows uses .cer extension for an X.509 certificate. These can be in "binary" (ASN.1 DER), or it can be encoded with Base-64 and have a header and footer applied (PEM); Windows will recognize either. To verify the integrity of a certificate, you have to check its signature using the issuer's public key... which is, in turn, another certificate.

Windows uses .pfx for a PKCS #12 file. This file can contain a variety of cryptographic information, including certificates, certificate chains, root authority certificates, and private keys. Its contents can be cryptographically protected (with passwords) to keep private keys private and preserve the integrity of root certificates.

Windows uses .pvk for a private key file. I'm not sure what standard (if any) Windows follows for these. Hopefully they are PKCS #8 encoded keys. Emmanuel Bourg reports that these are a proprietary format. Some documentation is available.

You should never disclose your private key. These are contained in .pfx and .pvk files.

Generally, you only exchange your certificate (.cer) and the certificates of any intermediate issuers (i.e., the certificates of all of your CAs, except the root CA) with other parties.

The way I do it is:

• Always put the join conditions in the ON clause if you are doing an INNER JOIN. So, do not add any WHERE conditions to the ON clause, put them in the WHERE clause.

• If you are doing a LEFT JOIN, add any WHERE conditions to the ON clause for the table in the right side of the join. This is a must, because adding a WHERE clause that references the right side of the join will convert the join to an INNER JOIN.

  The exception is when you are looking for the records that are not in a particular table. You would add the reference to a unique identifier (that is not ever NULL) in the RIGHT JOIN table to the WHERE clause this way: WHERE t2.idfield IS NULL. So, the only time you should reference a table on the right side of the join is to find those records which are not in the table.

Just add this extension:

extension NSDate {
    var stringValue: String {
        let formatter = NSDateFormatter()
        formatter.dateFormat = "yourDateFormat"
        return formatter.stringFromDate(self)
    }
}

instead of this margin struggle just do

input{
    width:100%;
    background:transparent !important;
}

this way the cell border is visible and you can control row background color

This is how I did it -

1. Create my own MockSSLSocketFactory (Class attached below)
2. Use it to initialise DefaultHttpClient. Proxy settings need to be provided if a proxy is used.

Initialising DefaultHTTPClient -

SchemeRegistry schemeRegistry = new SchemeRegistry();
    schemeRegistry.register(new Scheme("http", 80, PlainSocketFactory.getSocketFactory()));
    schemeRegistry.register(new Scheme("https", 443, new MockSSLSocketFactory()));
    ClientConnectionManager cm = new SingleClientConnManager(schemeRegistry);

    DefaultHttpClient httpclient = new DefaultHttpClient(cm);

Mock SSL Factory -

public class MockSSLSocketFactory extends SSLSocketFactory {

public MockSSLSocketFactory() throws NoSuchAlgorithmException, KeyManagementException, KeyStoreException, UnrecoverableKeyException {
    super(trustStrategy, hostnameVerifier);
}

private static final X509HostnameVerifier hostnameVerifier = new X509HostnameVerifier() {
    @Override
    public void verify(String host, SSLSocket ssl) throws IOException {
        // Do nothing
    }

    @Override
    public void verify(String host, X509Certificate cert) throws SSLException {
        //Do nothing
    }

    @Override
    public void verify(String host, String[] cns, String[] subjectAlts) throws SSLException {
        //Do nothing
    }

    @Override
    public boolean verify(String s, SSLSession sslSession) {
        return true; 
    }
};

private static final TrustStrategy trustStrategy = new TrustStrategy() {
    @Override
    public boolean isTrusted(X509Certificate[] chain, String authType) throws CertificateException {
        return true;
    }
};
}

If behind a proxy, need to do this -

HttpParams params = new BasicHttpParams();
    params.setParameter(AuthPNames.PROXY_AUTH_PREF, getClientAuthPrefs());

DefaultHttpClient httpclient = new DefaultHttpClient(cm, params);

httpclient.getCredentialsProvider().setCredentials(
                        new AuthScope(proxyHost, proxyPort),
                        new UsernamePasswordCredentials(proxyUser, proxyPass));

4 steps

1. npm install dotenv --save

2. Next add the following line to your app.

   require('dotenv').config()

3. Then create a .env file at the root directory of your application and add the variables to it.

// contents of .env 

REACT_APP_API_KEY = 'my-secret-api-key'

4. Finally, add .env to your .gitignore file so that Git ignores it and it never ends up on GitHub.

If you are using create-react-app then you only need step 3 and 4 but keep in mind variable needs to start with REACT_APP_ for it to work.

Reference: https://create-react-app.dev/docs/adding-custom-environment-variables/

NOTE - Need to restart application after adding variable in .env file.

In .NET Core (any version), you can use ImmutableList, which has all the functionality of List<T>.

just offering this up as a possible solution if you don't think the user will have a negative experience on the obvious change. I simply changed the body's class of overflow to hidden when the mouse was over the target div; then I changed the body's div to hidden overflow when the mouse leaves.

Personally I don't think it looks bad, my code could use toggle to make it cleaner, and there are obvious benefits for making this effect possible without the user being aware. So this is probably the hackish-last-resort answer.

//listen mouse on and mouse off for the button
pxMenu.addEventListener("mouseover", toggleA1);
pxOptContainer.addEventListener("mouseout", toggleA2);
//show / hide the pixel option menu
function toggleA1(){
  pxOptContainer.style.display = "flex";
  body.style.overflow = "hidden";
}
function toggleA2(){
  pxOptContainer.style.display = "none";
  body.style.overflow = "hidden scroll";
}

You can just use an a selector in your stylesheet to define all states of an anchor/hyperlink. For example:

a {
    color: blue;
}

Would override all link styles and make all the states the colour blue.

Glob function doesn't return the hidden files, therefore scandir can be more useful, when trying to delete recursively a tree.

<?php
public static function delTree($dir) {

KDiff3 open source, cross platform

Same interface for Linux and Windows, very smart algorithm for solving conflicts, regular expressions for automatically solving conflicts, integrate with ClearCase, SVN, Git, MS Visual Studio, editable merged file, compare directories

Its keyboard-navigation is great: ctrl-arrows to navigate the diffs, ctrl-1, 2, 3 to do the merging.

I hit this exact same error and was Googling all over trying to find what I'm doing wrong as that is generated build values-26 code and not styles that I provided. I tried everything from Gradle 4.0 to Android Studio preview 3.0 to canary channel, you name it.

I never found the answer online. In the end, I was able to go back to standard Dev Android Studio and 2.3.3 Gradle as I ended up accidentally fixing it :).

Turned out I was so focused on updating my library project that I was not noticing that the error was caused from an unused sub module (demo app) that is nested in my library project. Once I updated the sub module to match the 26 build tools and 26+ design and support libraries my problem went away.

Not sure if that is what you are seeing as well, but personally I was only updating the lib to release again so wasn't caring about the sample app module, and the error sure appeared to be related to 26 sdk which I only touched in the lib module so wasn't thinking to check the other one. So that was the problem all along for me. Hopefully that fixes you as well. I had this error in 2 library projects and it fixed it in both.

Goodluck either way and if this doesn't resolve your issue, please share what did. BTW 26.0.01 build tools and 26.1.0 design and support is where I ended up going to in the end, although 26.0.1 worked fine as well.

What is the difference between web service and WCF?

1. Web service use only HTTP protocol while transferring data from one application to other application.

   But WCF supports more protocols for transporting messages than ASP.NET Web services. WCF supports sending messages by using HTTP, as well as the Transmission Control Protocol (TCP), named pipes, and Microsoft Message Queuing (MSMQ).

2. To develop a service in Web Service, we will write the following code

   [WebService]
   public class Service : System.Web.Services.WebService
   {
     [WebMethod]
     public string Test(string strMsg)
     {
       return strMsg;
     }
   }
   

   To develop a service in WCF, we will write the following code

   [ServiceContract]
   public interface ITest
   {
     [OperationContract]
     string ShowMessage(string strMsg);
   }
   public class Service : ITest
   {
     public string ShowMessage(string strMsg)
     {
        return strMsg;
     }
   }
   

3. Web Service is not architecturally more robust. But WCF is architecturally more robust and promotes best practices.

4. Web Services use XmlSerializer but WCF uses DataContractSerializer. Which is better in performance as compared to XmlSerializer?

5. For internal (behind firewall) service-to-service calls we use the net:tcp binding, which is much faster than SOAP.

   WCF is 25%—50% faster than ASP.NET Web Services, and approximately 25% faster than .NET Remoting.

When would I opt for one over the other?

• WCF is used to communicate between other applications which has been developed on other platforms and using other Technology.

  For example, if I have to transfer data from .net platform to other application which is running on other OS (like Unix or Linux) and they are using other transfer protocol (like WAS, or TCP) Then it is only possible to transfer data using WCF.

• Here is no restriction of platform, transfer protocol of application while transferring the data between one application to other application.

• Security is very high as compare to web service

git clone --depth 1 --branch <tag_name> <repo_url>

Example

git clone --depth 1 --branch 0.37.2 https://github.com/apache/incubator-superset.git

<tag_name> : 0.37.2

<repo_url> : https://github.com/apache/incubator-superset.git

You can create an xml bitmap and use it as background for the view. To prevent stretching you can specify android:gravity attribute.

for example:

<?xml version="1.0" encoding="utf-8"?>
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
    android:src="@drawable/dvdr"
    android:tileMode="disabled" android:gravity="top" >
</bitmap>

There are a lot of options you can use to customize the rendering of the image

http://developer.android.com/guide/topics/resources/drawable-resource.html#Bitmap

This is an improved implementation of dubbe's solution which prevent scrolling.

// Javascript to enable link to tab
var url = document.location.toString();
if (url.match('#')) {
    $('.nav-tabs a[href="#'+url.split('#')[1]+'"]').tab('show') ;
} 

// With HTML5 history API, we can easily prevent scrolling!
$('.nav-tabs a').on('shown.bs.tab', function (e) {
    if(history.pushState) {
        history.pushState(null, null, e.target.hash); 
    } else {
        window.location.hash = e.target.hash; //Polyfill for old browsers
    }
})

As of SLF4J 1.6.0, in the presence of multiple parameters and if the last argument in a logging statement is an exception, then SLF4J will presume that the user wants the last argument to be treated as an exception and not a simple parameter. See also the relevant FAQ entry.

So, writing (in SLF4J version 1.7.x and later)

 logger.error("one two three: {} {} {}", "a", "b", 
              "c", new Exception("something went wrong"));

or writing (in SLF4J version 1.6.x)

 logger.error("one two three: {} {} {}", new Object[] {"a", "b", 
              "c", new Exception("something went wrong")});

will yield

one two three: a b c
java.lang.Exception: something went wrong
    at Example.main(Example.java:13)
    at java.lang.reflect.Method.invoke(Method.java:597)
    at ...

The exact output will depend on the underlying framework (e.g. logback, log4j, etc) as well on how the underlying framework is configured. However, if the last parameter is an exception it will be interpreted as such regardless of the underlying framework.

When you use strace (on Linux) to run your binary, it will output the returns from system calls and what the error number means. This may sometimes be useful to you.

I would combine node-http-proxy and express.

node-http-proxy will support a proxy inside your node.js web server via RoutingProxy (see the example called Proxy requests within another http server).

Inside your custom server logic you can do authentication using express. See the auth sample here for an example.

Combining those two examples should give you what you want.

You can use .ajaxStop() or .ajaxComplete()

.ajaxComplete() fires after completion of each AJAX request on your page.

$( document ).ajaxComplete(function() {
  yourFunction();
});

.ajaxStop() fires after completion of all AJAX requests on your page.

$( document ).ajaxStop(function() {
  yourFunction();
});

This seems to be fixed in Indigo Eclipse now, there's a video showing someone install android eclipse on youtube?

We had to mock HttpContext by using a HttpContextManager and calling the factory from within our application as well as the Unit Tests

public class HttpContextManager 
{
    private static HttpContextBase m_context;
    public static HttpContextBase Current
    {
        get
        {
            if (m_context != null)
                return m_context;

            if (HttpContext.Current == null)
                throw new InvalidOperationException("HttpContext not available");

            return new HttpContextWrapper(HttpContext.Current);
        }
    }

    public static void SetCurrentContext(HttpContextBase context)
    {
        m_context = context;
    }
}

You would then replace any calls to HttpContext.Current with HttpContextManager.Current and have access to the same methods. Then when you're testing, you can also access the HttpContextManager and mock your expectations

This is an example using Moq:

private HttpContextBase GetMockedHttpContext()
{
    var context = new Mock<HttpContextBase>();
    var request = new Mock<HttpRequestBase>();
    var response = new Mock<HttpResponseBase>();
    var session = new Mock<HttpSessionStateBase>();
    var server = new Mock<HttpServerUtilityBase>();
    var user = new Mock<IPrincipal>();
    var identity = new Mock<IIdentity>();
    var urlHelper = new Mock<UrlHelper>();

    var routes = new RouteCollection();
    MvcApplication.RegisterRoutes(routes);
    var requestContext = new Mock<RequestContext>();
    requestContext.Setup(x => x.HttpContext).Returns(context.Object);
    context.Setup(ctx => ctx.Request).Returns(request.Object);
    context.Setup(ctx => ctx.Response).Returns(response.Object);
    context.Setup(ctx => ctx.Session).Returns(session.Object);
    context.Setup(ctx => ctx.Server).Returns(server.Object);
    context.Setup(ctx => ctx.User).Returns(user.Object);
    user.Setup(ctx => ctx.Identity).Returns(identity.Object);
    identity.Setup(id => id.IsAuthenticated).Returns(true);
    identity.Setup(id => id.Name).Returns("test");
    request.Setup(req => req.Url).Returns(new Uri("http://www.google.com"));
    request.Setup(req => req.RequestContext).Returns(requestContext.Object);
    requestContext.Setup(x => x.RouteData).Returns(new RouteData());
    request.SetupGet(req => req.Headers).Returns(new NameValueCollection());

    return context.Object;
}

and then to use it within your unit tests, I call this within my Test Init method

HttpContextManager.SetCurrentContext(GetMockedHttpContext());

you can then, in the above method add the expected results from Session that you're expecting to be available to your web service.

I think I know this one...

Try sending your JSON as JSON by using PHP's header() function:

/**
 * Send as JSON
 */
header("Content-Type: application/json", true);

Though you are passing valid JSON, jQuery's $.ajax doesn't think so because it's missing the header.

jQuery used to be fine without the header, but it was changed a few versions back.

ALSO

Be sure that your script is returning valid JSON. Use Firebug or Google Chrome's Developer Tools to check the request's response in the console.

UPDATE

You will also want to update your code to sanitize the $_POST to avoid sql injection attacks. As well as provide some error catching.

if (isset($_POST['get_member'])) {

    $member_id = mysql_real_escape_string ($_POST["get_member"]);

    $query = "SELECT * FROM `members` WHERE `id` = '" . $member_id . "';";

    if ($result = mysql_query( $query )) {

       $row = mysql_fetch_array($result);

       $type = $row['type'];
       $name = $row['name'];
       $fname = $row['fname'];
       $lname = $row['lname'];
       $email = $row['email'];
       $phone = $row['phone'];
       $website = $row['website'];
       $image = $row['image'];

       /* JSON Row */
       $json = array( "type" => $type, "name" => $name, "fname" => $fname, "lname" => $lname, "email" => $email, "phone" => $phone, "website" => $website, "image" => $image );

    } else {

        /* Your Query Failed, use mysql_error to report why */
        $json = array('error' => 'MySQL Query Error');

    }

     /* Send as JSON */
     header("Content-Type: application/json", true);

    /* Return JSON */
    echo json_encode($json);

    /* Stop Execution */
    exit;

}

Very late to the party but here is a generic solution that works with every index value.

1. You create and spread new array from the old array up to the index you want to change.

2. Add the data you want.

3. Create and spread new array from the index you wanted to change to the end of the array

let index=1;// probabbly action.payload.id
case 'SOME_ACTION':
   return { 
       ...state, 
       contents: [
          ...state.contents.slice(0,index),
          {title: "some other title", text: "some other text"},
         ...state.contents.slice(index+1)
         ]
    }

Update:

I have made a small module to simplify the code, so you just need to call a function:

case 'SOME_ACTION':
   return {
       ...state,
       contents: insertIntoArray(state.contents,index, {title: "some title", text: "some text"})
    }

For more examples, take a look at the repository

function signature:

insertIntoArray(originalArray,insertionIndex,newData)

step 1: run this script

SET FOREIGN_KEY_CHECKS=0;

step 2: add column

ALTER TABLE mileage_unit ADD COLUMN COMPANY_ID BIGINT(20) NOT NULL

step 3: add foreign key to the added column

ALTER TABLE mileage_unit
ADD FOREIGN KEY (COMPANY_ID) REFERENCES company_mst(COMPANY_ID);

step 4: run this script

SET FOREIGN_KEY_CHECKS=1;

You are right, the documentation lacks of those methods. However when I dug into rxjs repository, I found nice comments about tap (too long to paste here) and pipe operators:

  /**
   * Used to stitch together functional operators into a chain.
   * @method pipe
   * @return {Observable} the Observable result of all of the operators having
   * been called in the order they were passed in.
   *
   * @example
   *
   * import { map, filter, scan } from 'rxjs/operators';
   *
   * Rx.Observable.interval(1000)
   *   .pipe(
   *     filter(x => x % 2 === 0),
   *     map(x => x + x),
   *     scan((acc, x) => acc + x)
   *   )
   *   .subscribe(x => console.log(x))
   */

In brief:

Pipe: Used to stitch together functional operators into a chain. Before we could just do observable.filter().map().scan(), but since every RxJS operator is a standalone function rather than an Observable's method, we need pipe() to make a chain of those operators (see example above).

Tap: Can perform side effects with observed data but does not modify the stream in any way. Formerly called do(). You can think of it as if observable was an array over time, then tap() would be an equivalent to Array.forEach().

To enhance Fabian's one-liner; let us say that we want to ignore only exit status 1 but to preserve the exit status if it is anything else:

tar -czf sample.tar.gz dir1 dir2 || ( export ret=$?; [[ $ret -eq 1 ]] || exit "$ret" )

This does everything sandeep's script does, on one line.

Nested classes are just like regular classes, but:

• they have additional access restriction (as all definitions inside a class definition do),
• they don't pollute the given namespace, e.g. global namespace. If you feel that class B is so deeply connected to class A, but the objects of A and B are not necessarily related, then you might want the class B to be only accessible via scoping the A class (it would be referred to as A::Class).

Some examples:

Publicly nesting class to put it in a scope of relevant class

Assume you want to have a class SomeSpecificCollection which would aggregate objects of class Element. You can then either:

1. declare two classes: SomeSpecificCollection and Element - bad, because the name "Element" is general enough in order to cause a possible name clash

2. introduce a namespace someSpecificCollection and declare classes someSpecificCollection::Collection and someSpecificCollection::Element. No risk of name clash, but can it get any more verbose?

3. declare two global classes SomeSpecificCollection and SomeSpecificCollectionElement - which has minor drawbacks, but is probably OK.

4. declare global class SomeSpecificCollection and class Element as its nested class. Then:

   • you don't risk any name clashes as Element is not in the global namespace,
   • in implementation of SomeSpecificCollection you refer to just Element, and everywhere else as SomeSpecificCollection::Element - which looks +- the same as 3., but more clear
   • it gets plain simple that it's "an element of a specific collection", not "a specific element of a collection"
   • it is visible that SomeSpecificCollection is also a class.

In my opinion, the last variant is definitely the most intuitive and hence best design.

Let me stress - It's not a big difference from making two global classes with more verbose names. It just a tiny little detail, but imho it makes the code more clear.

Introducing another scope inside a class scope

This is especially useful for introducing typedefs or enums. I'll just post a code example here:

class Product {
public:
    enum ProductType {
        FANCY, AWESOME, USEFUL
    };
    enum ProductBoxType {
        BOX, BAG, CRATE
    };
    Product(ProductType t, ProductBoxType b, String name);

    // the rest of the class: fields, methods
};

One then will call:

Product p(Product::FANCY, Product::BOX);

But when looking at code completion proposals for Product::, one will often get all the possible enum values (BOX, FANCY, CRATE) listed and it's easy to make a mistake here (C++0x's strongly typed enums kind of solve that, but never mind).

But if you introduce additional scope for those enums using nested classes, things could look like:

class Product {
public:
    struct ProductType {
        enum Enum { FANCY, AWESOME, USEFUL };
    };
    struct ProductBoxType {
        enum Enum { BOX, BAG, CRATE };
    };
    Product(ProductType::Enum t, ProductBoxType::Enum b, String name);

    // the rest of the class: fields, methods
};

Then the call looks like:

Product p(Product::ProductType::FANCY, Product::ProductBoxType::BOX);

Then by typing Product::ProductType:: in an IDE, one will get only the enums from the desired scope suggested. This also reduces the risk of making a mistake.

Of course this may not be needed for small classes, but if one has a lot of enums, then it makes things easier for the client programmers.

In the same way, you could "organise" a big bunch of typedefs in a template, if you ever had the need to. It's a useful pattern sometimes.

The PIMPL idiom

The PIMPL (short for Pointer to IMPLementation) is an idiom useful to remove the implementation details of a class from the header. This reduces the need of recompiling classes depending on the class' header whenever the "implementation" part of the header changes.

It's usually implemented using a nested class:

X.h:

class X {
public:
    X();
    virtual ~X();
    void publicInterface();
    void publicInterface2();
private:
    struct Impl;
    std::unique_ptr<Impl> impl;
}

X.cpp:

#include "X.h"
#include <windows.h>

struct X::Impl {
    HWND hWnd; // this field is a part of the class, but no need to include windows.h in header
    // all private fields, methods go here

    void privateMethod(HWND wnd);
    void privateMethod();
};

X::X() : impl(new Impl()) {
    // ...
}

// and the rest of definitions go here

This is particularly useful if the full class definition needs the definition of types from some external library which has a heavy or just ugly header file (take WinAPI). If you use PIMPL, then you can enclose any WinAPI-specific functionality only in .cpp and never include it in .h.

With the Underscore.js

var arr=['a','a1','b'] _.filter(arr, function(a){ return a.indexOf('a') > -1; })

No such thing. the input type=date will pick up whatever your system default is and show that in the GUI but will always store the value in ISO format (yyyy-mm-dd). Beside be aware that not all browsers support this so it's not a good idea to depend on this input type yet.

If this is a corporate issue, force all the computer to use local regional format (dd-mm-yyyy) and your UI will show it in this format (see wufoo link before after changing your regional settings, you need to reopen the browser).

• See: http://www.wufoo.com/html5/types/4-date.html for example

• See: http://caniuse.com/#feat=input-datetime for browser supports

• See: https://www.w3.org/TR/2011/WD-html-markup-20110525/input.date.html for spec. <- no format attr.

Your best bet is still to use JavaScript based component that will allow you to customize this to whatever you wish.

In Chrome when you load a website from some HTTP server both absolute paths (e.g. /images/sth.png) and relative paths to some upper level directory (e.g. ../images/sth.png) work.

But!

When you load (in Chrome!) a HTML document from local filesystem you cannot access directories above current directory. I.e. you cannot access ../something/something.sth and changing relative path to absolute or anything else won't help.

Or, in order to avoid modifying slowFunc (say you don't have access to the source code for instance):

var source = new CancellationTokenSource(); //original code
source.Token.Register(CancelNotification); //original code
source.CancelAfter(TimeSpan.FromSeconds(1)); //original code
var completionSource = new TaskCompletionSource<object>(); //New code
source.Token.Register(() => completionSource.TrySetCanceled()); //New code
var task = Task<int>.Factory.StartNew(() => slowFunc(1, 2), source.Token); //original code

//original code: await task;  
await Task.WhenAny(task, completionSource.Task); //New code

You can also use nice extension methods from https://github.com/StephenCleary/AsyncEx and have it looks as simple as:

await Task.WhenAny(task, source.Token.AsTask());

The SCSS way for all elements (not only buttons):

body {
  * {
    &:focus, &.focus,
    &:active, &.active {
      outline: transparent none 0 !important;
      box-shadow: 0 0 0 0 rgba(0,123,255,0) !important;
      -webkit-box-shadow: none !important;
    }
  }
}

shift `expr $# - 1`
echo "$1"

This shifts the arguments by the number of arguments minus 1, and returns the first (and only) remaining argument, which will be the last one.

I only tested in bash, but it should work in sh and ksh as well.

Please find the simple solution to convete Date & Time Format in Go Lang. Please find the example below.

Package Link: https://github.com/vigneshuvi/GoDateFormat.

Please find the plackholders:https://medium.com/@Martynas/formatting-date-and-time-in-golang-5816112bf098

package main


// Import Package
import (
    "fmt"
    "time"
    "github.com/vigneshuvi/GoDateFormat"
)

func main() {
    fmt.Println("Go Date Format(Today - 'yyyy-MM-dd HH:mm:ss Z'): ", GetToday(GoDateFormat.ConvertFormat("yyyy-MM-dd HH:mm:ss Z")))
    fmt.Println("Go Date Format(Today - 'yyyy-MMM-dd'): ", GetToday(GoDateFormat.ConvertFormat("yyyy-MMM-dd")))
    fmt.Println("Go Time Format(NOW - 'HH:MM:SS'): ", GetToday(GoDateFormat.ConvertFormat("HH:MM:SS")))
    fmt.Println("Go Time Format(NOW - 'HH:MM:SS tt'): ", GetToday(GoDateFormat.ConvertFormat("HH:MM:SS tt")))
}

func GetToday(format string) (todayString string){
    today := time.Now()
    todayString = today.Format(format);
    return
}

Combining the two answers:

First create sql to make all index unusable:

alter session set skip_unusable_indexes = true;
select 'alter index ' || u.index_name || ' unusable;' from user_indexes u;

Do import...

select 'alter index ' || u.index_name || ' rebuild online;' from user_indexes u;

The rsa.pub (i.e. public key generated), needs to be added on the github>> settings>>ssh keys page. Check that, you have not added this public key in the repository-settings >> deployment keys. If so, remove the entry from here and add to the first place mentioned.

Setup of the pub-private keys in detail.

It will work hence!

This also might be useful to know, you can set a value and if someone provides input, override the default with that value..

myscript.sh -f ./serverlist.txt or just ./myscript.sh (and it takes defaults)

    #!/bin/bash
    # --- set the value, if there is inputs, override the defaults.

    HOME_FOLDER="${HOME}/owned_id_checker"
    SERVER_FILE_LIST="${HOME_FOLDER}/server_list.txt"

    while [[ $# > 1 ]]
    do
    key="$1"
    shift

    case $key in
        -i|--inputlist)
        SERVER_FILE_LIST="$1"
        shift
        ;;
    esac
    done


    echo "SERVER LIST   = ${SERVER_FILE_LIST}"

To me it seems like the best solution is to use a directive; there's no need for the controller to know that the view is being updated.

Javascript:

var app = angular.module('app', ['directives']);

angular.module('directives', []).directive('toggleClass', function () {
    var directiveDefinitionObject = {
        restrict: 'A',
        template: '<span ng-click="localFunction()" ng-class="selected"  ng-transclude></span>',
        replace: true,
        scope: {
            model: '='
        },
        transclude: true,
        link: function (scope, element, attrs) {
            scope.localFunction = function () {
                scope.model.value = scope.$id;
            };
            scope.$watch('model.value', function () {
                // Is this set to my scope?
                if (scope.model.value === scope.$id) {
                    scope.selected = "active";
                } else {
                    // nope
                    scope.selected = '';
                }
            });
        }
    };
    return directiveDefinitionObject;
});

HTML:

<div ng-app="app" ng-init="model = { value: 'dsf'}"> <span>Click a span... then click another</span>

<br/>
<br/>
<span toggle-class model="model">span1</span>

<br/><span toggle-class model="model">span2</span>

<br/><span toggle-class model="model">span3</span>

CSS:

.active {
     color:red;
 }

I have a fiddle that demonstrates. The idea is when a directive is clicked, a function is called on the directive that sets a variable to the current scope id. Then each directive also watches the same value. If the scope ID's match, then the current element is set to be active using ng-class.

The reason to use directives, is that you no longer are dependent on a controller. In fact I don't have a controller at all (I do define a variable in the view named "model"). You can then reuse this directive anywhere in your project, not just on one controller.

To get the user email, you have to log in the user with his Facebook account using the email permission. Use for that the Facebook PHP SDK (see on github) as following.

First check if the user is already logged in :

require "facebook.php";
$facebook = new Facebook(array(
    'appId'  => YOUR_APP_ID,
    'secret' => YOUR_APP_SECRET,
));

$user = $facebook->getUser();
if ($user) {
    try {
        $user_profile = $facebook->api('/me');
    } catch (FacebookApiException $e) {
        $user = null;
    }
}

If he his not, you can display the login link asking for the email permission :

if (!$user) {
    $args = array('scope' => 'email');
    echo '<a href="' . $facebook->getLoginUrl() . '">Login with Facebook</a>';
} else {
    echo '<a href="' . $facebook->getLogoutUrl() . '">Logout</a>';
}

When he is logged in the email can be found in the $user_profile array.

Hope that helps !

Both function and perform similarly, but still differ in following ways.

Web application:

1. We can't include C# and VB page in single web application.

2. We can set up dependencies between multiple projects.

3. Can not edit individual files after deployment without recompiling.

4. Right choice for enterprise environments where multiple developers work unitedly for creating,testing and deployment.

Web site:

1. Can mix VB and C# page in single website.
2. Can not establish dependencies.
3. Edit individual files after deployment.
4. Right choice when one developer will responsible for creating and managing entire website.

When you are creating an object of intent, you can take advantage of following two methods for passing objects between two activities.

putParcelable

putSerializable

You can have your class implement either Parcelable or Serializable. Then you can pass around your custom classes across activities. I have found this very useful.

Here is a small snippet of code I am using

CustomListing currentListing = new CustomListing();
Intent i = new Intent();
Bundle b = new Bundle();
b.putParcelable(Constants.CUSTOM_LISTING, currentListing);
i.putExtras(b);
i.setClass(this, SearchDetailsActivity.class);
startActivity(i);

And in newly started activity code will be something like this...

Bundle b = this.getIntent().getExtras();
if (b != null)
    mCurrentListing = b.getParcelable(Constants.CUSTOM_LISTING);

this metod delate all data from database

 public void deleteAll()
{
    SQLiteDatabase db = this.getWritableDatabase();
    db.execSQL("delete from "+ TABLE_NAME);
    db.close();
}

I find attributes to be cleaner to use than manually adding them via code. Here is a simple example.

[RoutePrefix("api/example")]
public class ExampleController : ApiController
{
    [HttpGet]
    [Route("get1/{param1}")] //   /api/example/get1/1?param2=4
    public IHttpActionResult Get(int param1, int param2)
    {
        Object example = null;
        return Ok(example);
    }

}

You also need this in your webapiconfig

config.Routes.MapHttpRoute(
    name: "DefaultApi",
    routeTemplate: "api/{controller}/{id}",
    defaults: new { id = RouteParameter.Optional }
);

config.Routes.MapHttpRoute(
    name: "ActionApi",
    routeTemplate: "api/{controller}/{action}/{id}",
    defaults: new { id = RouteParameter.Optional }
);

On linux you can check epiphany-browser, resizes the windows you'll get same bugs as in ios. Both browsers uses Webkit.

sudo apt install epiphany-browser

I am not sure if this applies to the older version of chosen,but now in the current version(v1.4.1) they have a option $('#autoship_option').chosen({ allow_single_deselect:true }); This will add a 'x' icon next to the name selected.Use the 'x' to clear the 'select' feild.

PS:make sure you have 'chosen-sprite.png' in the right place as per the chosen.css so that the icons are visible.

you just need to divide the Date Time stamp by 1000 like:

var a = 1437203995000;
a = (a)/1000;

I think you want to cast your dt to a date and fix the format of your date literal:

SELECT *
FROM table
WHERE dt::date = '2011-01-01' -- This should be ISO-8601 format, YYYY-MM-DD

Or the standard version:

SELECT *
FROM table
WHERE CAST(dt AS DATE) = '2011-01-01' -- This should be ISO-8601 format, YYYY-MM-DD

The extract function doesn't understand "date" and it returns a number.

I ran into this myself and ended up with a solution, that is similar to several answers here, but implemented slightly differently. I didn't like many pieces of javascript, or a placeholder div somewhere. I wanted a generalized solution, that could then be used in HTML without adding javascript for each use. Here is what I came up with (this requires jquery ui):

Javascript:

$(function() {

  $("a.confirm").button().click(function(e) {

    e.preventDefault();

    var target = $(this).attr("href");
    var content = $(this).attr("title");
    var title = $(this).attr("alt");

    $('<div>' + content + '</div>'). dialog({
      draggable: false,
      modal: true,
      resizable: false,
      width: 'auto',
      title: title,
      buttons: {
        "Confirm": function() {
          window.location.href = target;
        },
        "Cancel": function() {
          $(this).dialog("close");
        }
      }
    });

  });

});

And then in HTML, no javascript calls or references are needed:

<a href="http://www.google.com/"
   class="confirm"
   alt="Confirm test"
   title="Are you sure?">Test</a>

Since the title attribute is used for the div content, the user can even get the confirmation question by hovering over the button (which is why i didn't user the title attribute for the tile). The title of the confirmation window is the content of the alt tag. The javascript snip can be included in a generalized .js include, and simply by applying a class you have a pretty confirmation window.

Just a few suggestions:

• Screenshots might be an easy way, but you'll have to make sure the code in the image is big enough and clear enough to read. (not the whole screenshot, just the relevant part)
• If you can embed html then there are lots of tools to generate syntax highlighted html.

The answer I got is that variables and subqueries will not work and we have to user dynamic SQL script. The following works:

DECLARE @SQL VARCHAR(4000)
SET @SQL = 'ALTER TABLE dbo.Student DROP CONSTRAINT |ConstraintName| '

SET @SQL = REPLACE(@SQL, '|ConstraintName|', ( SELECT   name
                                               FROM     sysobjects
                                               WHERE    xtype = 'PK'
                                                        AND parent_obj =        OBJECT_ID('Student')))

EXEC (@SQL)

I had a similar problem but I came to a different solution that may help others. I used Spring Profiles to separate out test and app configuration classes.

1. Create a TestConfig class with a specific profile and exclude any app configuration from component scan you wish here.

2. In your test class set the profile to match the TestConfig and include it using the @ContextConfiguration annotation.

For example:

configuration:

@Profile("test")
@Configuration
@EnableWebMvc
@ComponentScan(
    basePackages="your.base.package",
    excludeFilters = {
            @Filter(type = ASSIGNABLE_TYPE,
                    value = {
                            ExcludedAppConfig1.class,
                            ExcludedAppConfig2.class
            })
    })
public class TestConfig { ...}

test:

@ActiveProfiles("test")
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = TestConfig.class)
@WebAppConfiguration
public class SomeTest{ ... }

If you have renamed a file locally and then do a pull, it will display that error message.

The benefit is that the output of previous function is used. You do not need to repeat where the data source comes from, for example.

I think it will help you

<script type="text/javascript">
function isNumberKey(evt) {
    var charCode = (evt.which) ? evt.which : event.keyCode
    if (charCode > 32 && (charCode < 48 || charCode > 57) && (charCode != 45) && (charCode != 43) && (charCode != 40) && (charCode != 41))
        return false;

    return true;
}

Try this:

def date = Date.parse("E MMM dd H:m:s z yyyy", dateStr)

Here are the patterns to format the dates

var arr = [1,2,2,3,4,5,5,5,6,7,7,8,9,10,10];

function squash(arr){
    var tmp = [];
    for(var i = 0; i < arr.length; i++){
        if(tmp.indexOf(arr[i]) == -1){
        tmp.push(arr[i]);
        }
    }
    return tmp;
}

console.log(squash(arr));

To make this work on Ubuntu Linux:

1. I installed the Ubuntu package ruby-json:

   apt-get install ruby-json
   

2. I wrote the script in ${HOME}/rubybin/jsonDEMO

3. $HOME/.bashrc included:

   ${HOME}/rubybin:${PATH}
   

(On this occasion I also typed the above on the bash command line.)

Then it worked when I entered on the command line:

jsonDemo

I will throw in what worked for me in the end. I needed to remove the initial commit on a repository as quarantined data had been misplaced, the commit had already been pushed.

Make sure you are are currently on the right branch.

git checkout master

git update-ref -d HEAD

git commit -m "Initial commit

git push -u origin master

This was able to resolve the problem.

Important

This was on an internal repository which was not publicly accessible, if your repository was publicly accessible please assume anything you need to revert has already been pulled down by someone else.

Try moving the seed srand outside the loop like so:

srand ( time(NULL) );
for (int t=0;t<10;t++)
{
    int random_x;
    random_x = rand() % 100;
    cout<< "\nRandom X = "<<random_x;
} 

As Mark Ransom says in the comment, moving the seed outside the loop will only help if the loop is not residing in a function you are calling several times.

Have a look at jQuery's .parseXML() ^[docs]:

After looking for a way to solve this problem, without loading any Python 3 module or extra mathematical operations, I solved the problem using only str.format() e .float(). I think this way is faster than using other mathematical operations, like in the most commom solution. I needed a fast solution because I work with a very very large dataset and so for its working very well here.

def truncate_number(f_number, n_decimals):
      strFormNum = "{0:." + str(n_decimals+5) + "f}"
      trunc_num = float(strFormNum.format(f_number)[:-5])
      return(trunc_num)

# Testing the 'trunc_num()' function
test_num = 1150/252
[(idx, truncate_number(test_num, idx)) for idx in range(0, 20)]

It returns the following output:

[(0, 4.0),
 (1, 4.5),
 (2, 4.56),
 (3, 4.563),
 (4, 4.5634),
 (5, 4.56349),
 (6, 4.563492),
 (7, 4.563492),
 (8, 4.56349206),
 (9, 4.563492063),
 (10, 4.5634920634),
 (11, 4.56349206349),
 (12, 4.563492063492),
 (13, 4.563492063492),
 (14, 4.56349206349206),
 (15, 4.563492063492063),
 (16, 4.563492063492063),
 (17, 4.563492063492063),
 (18, 4.563492063492063),
 (19, 4.563492063492063)]

If you have a multi-dimensional array you can use on PHP 5.5+ this:

array_count_values(array_column($array, 'key'))

which returns e.g.

 [
   'keyA' => 4,
   'keyB' => 2,
 ]

I think you can simply use a LinkedList in your stack implementation.

First time you push a value, you put this value as the linkedlist head.

then each time you push a value, if the new value < head.data, make a prepand operation ( which means the head becomes the new value )

if not, then make an append operation.

When you make a pop(), you check if min == linkedlist.head.data, if yes, then head=head.next;

Here is my code.

public class Stack {

int[] elements;
int top;
Linkedlists min;

public Stack(int n) {
    elements = new int[n];
    top = 0;
    min = new Linkedlists();
}

public void realloc(int n) {
    int[] tab = new int[n];
    for (int i = 0; i < top; i++) {
        tab[i] = elements[i];
    }

    elements = tab;
}

public void push(int x) {
    if (top == elements.length) {
        realloc(elements.length * 2);
    }
    if (top == 0) {
        min.pre(x);
    } else if (x < min.head.data) {
        min.pre(x);
    } else {
        min.app(x);
    }
    elements[top++] = x;
}

public int pop() {

    int x = elements[--top];
    if (top == 0) {

    }
    if (this.getMin() == x) {
        min.head = min.head.next;
    }
    elements[top] = 0;
    if (4 * top < elements.length) {
        realloc((elements.length + 1) / 2);
    }

    return x;
}

public void display() {
    for (Object x : elements) {
        System.out.print(x + " ");
    }

}

public int getMin() {
    if (top == 0) {
        return 0;
    }
    return this.min.head.data;
}

public static void main(String[] args) {
    Stack stack = new Stack(4);
    stack.push(2);
    stack.push(3);
    stack.push(1);
    stack.push(4);
    stack.push(5);
    stack.pop();
    stack.pop();
    stack.pop();
    stack.push(1);
    stack.pop();
    stack.pop();
    stack.pop();
    stack.push(2);
    System.out.println(stack.getMin());
    stack.display();

}

 }

The accepted solution only works on arrays, but not objects or associative arrays. Unfortunately, since Angular depends on the JavaScript implementation of array enumeration, the order of object properties cannot be consistently controlled. Some browsers may iterate through object properties lexicographically, but this cannot be guaranteed.

e.g. Given the following assignment:

$scope.cards = {
  "card2": {
    values: {
      opt1: 9,
      opt2: 12
    }
  },
  "card1": {
    values: {
      opt1: 9,
      opt2: 11
    }
  }
};

and the directive <ul ng-repeat="(key, card) in cards | orderBy:myValueFunction">, ng-repeat may iterate over "card1" prior to "card2", regardless of sort order.

To workaround this, we can create a custom filter to convert the object to an array, and then apply a custom sort function before returning the collection.

myApp.filter('orderByValue', function () {
  // custom value function for sorting
  function myValueFunction(card) {
    return card.values.opt1 + card.values.opt2;
  }

  return function (obj) {
    var array = [];
    Object.keys(obj).forEach(function (key) {
      // inject key into each object so we can refer to it from the template
      obj[key].name = key;
      array.push(obj[key]);
    });
    // apply a custom sorting function
    array.sort(function (a, b) {
      return myValueFunction(b) - myValueFunction(a);
    });
    return array;
  };
});

We cannot iterate over (key, value) pairings in conjunction with custom filters (since the keys for arrays are numerical indexes), so the template should be updated to reference the injected key names.

<ul ng-repeat="card in cards | orderByValue">
    <li>{{card.name}} {{value(card)}}</li>
</ul>

Here is a working fiddle utilizing a custom filter on an associative array: http://jsfiddle.net/av1mLpqx/1/

:nth-child is the answer you are looking for.

I've been going back and forth on these two options the last few times I've needed them. Up until recently, my preference has been for the sealed trait/case object option.

1) Scala Enumeration Declaration

object OutboundMarketMakerEntryPointType extends Enumeration {
  type OutboundMarketMakerEntryPointType = Value

  val Alpha, Beta = Value
}

2) Sealed Traits + Case Objects

sealed trait OutboundMarketMakerEntryPointType

case object AlphaEntryPoint extends OutboundMarketMakerEntryPointType

case object BetaEntryPoint extends OutboundMarketMakerEntryPointType

While neither of these really meet all of what a java enumeration gives you, below are the pros and cons:

Scala Enumeration

Pros: -Functions for instantiating with option or directly assuming accurate (easier when loading from a persistent store) -Iteration over all possible values is supported

Cons: -Compilation warning for non-exhaustive search is not supported (makes pattern matching less ideal)

Case Objects/Sealed traits

Pros: -Using sealed traits, we can pre-instantiate some values while others can be injected at creation time -full support for pattern matching (apply/unapply methods defined)

Cons: -Instantiating from a persistent store - you often have to use pattern matching here or define your own list of all possible 'enum values'

What ultimately made me change my opinion was something like the following snippet:

object DbInstrumentQueries {
  def instrumentExtractor(tableAlias: String = "s")(rs: ResultSet): Instrument = {
    val symbol = rs.getString(tableAlias + ".name")
    val quoteCurrency = rs.getString(tableAlias + ".quote_currency")
    val fixRepresentation = rs.getString(tableAlias + ".fix_representation")
    val pointsValue = rs.getInt(tableAlias + ".points_value")
    val instrumentType = InstrumentType.fromString(rs.getString(tableAlias +".instrument_type"))
    val productType = ProductType.fromString(rs.getString(tableAlias + ".product_type"))

    Instrument(symbol, fixRepresentation, quoteCurrency, pointsValue, instrumentType, productType)
  }
}

object InstrumentType {
  def fromString(instrumentType: String): InstrumentType = Seq(CurrencyPair, Metal, CFD)
  .find(_.toString == instrumentType).get
}

object ProductType {

  def fromString(productType: String): ProductType = Seq(Commodity, Currency, Index)
  .find(_.toString == productType).get
}

The .get calls were hideous - using enumeration instead I can simply call the withName method on the enumeration as follows:

object DbInstrumentQueries {
  def instrumentExtractor(tableAlias: String = "s")(rs: ResultSet): Instrument = {
    val symbol = rs.getString(tableAlias + ".name")
    val quoteCurrency = rs.getString(tableAlias + ".quote_currency")
    val fixRepresentation = rs.getString(tableAlias + ".fix_representation")
    val pointsValue = rs.getInt(tableAlias + ".points_value")
    val instrumentType = InstrumentType.withNameString(rs.getString(tableAlias + ".instrument_type"))
    val productType = ProductType.withName(rs.getString(tableAlias + ".product_type"))

    Instrument(symbol, fixRepresentation, quoteCurrency, pointsValue, instrumentType, productType)
  }
}

So I think my preference going forward is to use Enumerations when the values are intended to be accessed from a repository and case objects/sealed traits otherwise.

You can create an ExtensionMethod to do that!

public static class StringExtension
{
  public static string Repeat(this string str, int count)
  {
    string ret = "";

    for (var x = 0; x < count; x++)
    {
      ret += str;
    }

    return ret;
  }
}

Or using @Dan Tao solution:

public static class StringExtension
{
  public static string Repeat(this string str, int count)
  {
    if (count == 0)
      return "";

    return string.Concat(Enumerable.Repeat(indent, N))
  }
}

Adding to the accepted answer, you can used DATABASE_DEFAULT as encoding.

This allows database to make choice for you and your code becomes more portable.

SELECT MyColumn
FROM 
    FirstTable a
        INNER JOIN SecondTable b
            ON a.MyID COLLATE DATABASE_DEFAULT = b.YourID COLLATE DATABASE_DEFAULT

May be you need Decimal

>>> from decimal import Decimal    
>>> Decimal(2.675)
Decimal('2.67499999999999982236431605997495353221893310546875')

Floating Point Arithmetic

Try using the SQL_NO_CACHE (MySQL 5.7) option in your query. (MySQL 5.6 users click HERE )

eg.

SELECT SQL_NO_CACHE * FROM TABLE

This will stop MySQL caching the results, however be aware that other OS and disk caches may also impact performance. These are harder to get around.

Just to add to Serzas' answer(since don't have enough reps. to comment). alphabets and numbers can effectively be replaced by \w for words. Additionally apostrophe,comma,period and hyphen doesn't necessarily need a backslash. My requirement also involved front and back slashes so \/ and finally whitespaces with \s. The working regex for me ,as such was :

pattern: "[\w',-\\/.\s]"

Today i deep in State Design Pattern. I did and tested ThreadState, which equal (+/-) to Threading in C#, as described in picture from Threading in C#

You can easly add new states, configure moves from one state to other is very easy becouse it incapsulated in state implementation

Implementation and using at: Implements .NET ThreadState by State Design Pattern

UPDATE

Bootstrap 4 has spacing utilities to handle this https://getbootstrap.com/docs/4.0/utilities/spacing/

.mt-0 {
  margin-top: 0 !important;
}

--

ORIGINAL ANSWER

If you are using SASS, this is what I normally do.

$margins: (xs: 0.5rem, sm: 1rem, md: 1.5rem, lg: 2rem, xl: 2.5rem);

@each $name, $value in $margins {
  .margin-top-#{$name} {
    margin-top: $value;
  }

  .margin-bottom-#{$name} {
    margin-bottom: $value;
  }
}

so you can later use margin-top-xs for example

You can also try executing the 'convert' utility that comes with imagemagick.

exec("convert pdf_doc.pdf image.jpg");
echo 'image-0.jpg';

You should read up on the onclick html attribute and the window.open() documentation. Below is what you want.

<a href='#' onclick='window.open("http://www.google.com", "myWin", "scrollbars=yes,width=400,height=650"); return false;'>1</a>

You application of js and php in totally invalid.

You have to understand a fact that JS runs on clientside, once the page loads it does not care, whether the page was a php page or jsp or asp. It executes of DOM and is related to it only.

However you can do something like this

var newLocation = "<?php echo $newlocation; ?>";
window.location = newLocation;

You see, by the time the script is loaded, the above code renders into different form, something like this

var newLocation = "your/redirecting/page.php";
window.location = newLocation;

Like above, there are many possibilities of php and js fusions and one you are doing is not one of them.

If you want to revert the changes only in current working directory, use

git checkout -- .

And before that, you can list the files that will be reverted without actually making any action, just to check what will happen, with:

git checkout --

Expanding on @Kazetsukai's answer, you may run into this problem if you are making your AJAX request from the user clicking on a link.

If you set up your link like so:

<a href="#" onclick="soAjax()">click me!</a>

And then a javascript handler like the following:

soAjax() {
    $.ajax({ ... all your lovely parameters ... });       
}

To prevent your browser from following the link and cancelling any requests in progress, you should add return false or e.preventDefault() to stop the click event from propagating:

soAjax() {
   $.ajax({ ... etc ... });
   return false;
}

Or:

soAjax(e) {
   $.ajax({ ... etc ... });
   e.preventDefault();
}

There are many ways to check the size, but as a developer we dont have much access to query meta tables, I find this solution very easy (Note: if you are getting error message ORA-01653 ‘The ORA-01653 error is caused because you need to add space to a tablespace.’)

--2. Free Space
SELECT TABLESPACE_NAME,TO_CHAR(SUM(NVL(BYTES,0))/1024/1024/1024, '99,999,990.99') AS "FREE SPACE(IN GB)" FROM   USER_FREE_SPACE GROUP BY TABLESPACE_NAME

--3. Both Free & Used
SELECT USED.TABLESPACE_NAME, USED.USED_BYTES AS "USED SPACE(IN GB)",  FREE.FREE_BYTES AS "FREE SPACE(IN GB)"

Export the SELECT result

• After you run a SELECT: Query > Export Results...

  

Export table data

• In the Navigator, right click on the table > Table Data Export Wizard

  

• All columns and rows are included by default, so click on Next.

• Select File Path, type, Field Separator (by default it is ;, not ,!!!) and click on Next.

  

• Click Next > Next > Finish and the file is created in the specified location

Reading console input is hard, you need to handle special keys like Ctrl, Alt, also cursor keys and Backspace/Delete. On some keyboard layouts, like Swedish Ctrl is even needed to enter keys that exist directly on US keyboard. I believe that trying to handle this using the "low-level" Console.ReadKey(true) is just very hard, so the easiest and most robust way is to just to disable "console input echo" during entering password using a bit of WINAPI.

The sample below is based on answer to Read a password from std::cin question.

    private enum StdHandle
    {
        Input = -10,
        Output = -11,
        Error = -12,
    }

    private enum ConsoleMode
    {
        ENABLE_ECHO_INPUT = 4
    }

    [DllImport("kernel32.dll", SetLastError = true)]
    private static extern IntPtr GetStdHandle(StdHandle nStdHandle);

    [DllImport("kernel32.dll", SetLastError = true)]
    [return: MarshalAs(UnmanagedType.Bool)]
    private static extern bool GetConsoleMode(IntPtr hConsoleHandle, out int lpMode);

    [DllImport("kernel32.dll", SetLastError = true)]
    [return: MarshalAs(UnmanagedType.Bool)]
    private static extern bool SetConsoleMode(IntPtr hConsoleHandle, int dwMode);

    public static string ReadPassword()
    {
        IntPtr stdInputHandle = GetStdHandle(StdHandle.Input);
        if (stdInputHandle == IntPtr.Zero)
        {
            throw new InvalidOperationException("No console input");
        }

        int previousConsoleMode;
        if (!GetConsoleMode(stdInputHandle , out previousConsoleMode))
        {
            throw new Win32Exception(Marshal.GetLastWin32Error(), "Could not get console mode.");
        }

        // disable console input echo
        if (!SetConsoleMode(stdInputHandle , previousConsoleMode & ~(int)ConsoleMode.ENABLE_ECHO_INPUT))
        {
            throw new Win32Exception(Marshal.GetLastWin32Error(), "Could not disable console input echo.");
        }

        // just read the password using standard Console.ReadLine()
        string password = Console.ReadLine();

        // reset console mode to previous
        if (!SetConsoleMode(stdInputHandle , previousConsoleMode))
        {
            throw new Win32Exception(Marshal.GetLastWin32Error(), "Could not reset console mode.");
        }

        return password;
    }

Quick answer

On src, you can always specify files to ignore using "!".

Example (you want to exclude all *.min.js files on your js folder and subfolder:

gulp.src(['js/**/*.js', '!js/**/*.min.js'])

You can do it as well for individual files.

Expanded answer:

Extracted from gulp documentation:

gulp.src(globs[, options])

Emits files matching provided glob or an array of globs. Returns a stream of Vinyl files that can be piped to plugins.

glob refers to node-glob syntax or it can be a direct file path.

So, looking to node-glob documentation we can see that it uses the minimatch library to do its matching.

On minimatch documentation, they point out the following:

if the pattern starts with a ! character, then it is negated.

And that is why using ! symbol will exclude files / directories from a gulp task

Where x is the collection:

Foo[] foos = x.toArray(new Foo[x.size()]);

Maybe this could work, but I don't know if this is valid HTML.

<form method="get" action="something.php">
    <input type="text" name="name" />
    <input id="submitButton" type="submit" class="hide-submit" />
</form>

<label for="submitButton">Submit</label>

Open Visual Studio Code and press Command + Shift + P then type Shell in command palette now you are able to find this option like Shell Command : Install code in PATH from suggested list in command palette. Select that options.

I think a good question would be: how does HTTP work? Working with GET and POST data among other HTTP communications is inherent in PHP development. Understanding how HTTP works in a broader context and how PHP implements this goes a long way.

Additional thoughts :

Ramdisk - setting the temp drive MySQL uses as a RAM disk, very easy to set up.

memcache - memcache server is easy to set up, use it to store the results of your queries for X amount of time.

Maybe there is another way to solve this problem using rotation of coordinate system.

Normally, if one segment is horizontal or vertical, which means parallel to x or y axis, it's quite easy to solve the intersection point since we already know one coordinate of the intersection, if any. The rest is obviously finding the other coordinate using circle's equation.

Inspired by this idea, we could apply coordinates system rotation to make one axis's direction coincide with segment's direction.

Let's take an example of circle x^2+y^2=1 and segment P1-P2 with P1(-1.5,0.5) and P2(-0.5,-0.5) in x-y system. And the following equations to remind you of the rotation principles, where theta is the angle anticlockwise, x'-y' is the system after rotation :

x' = x * cos(theta) + y * sin(theta)

y' = - x * sin(theta) + y * cos(theta)

and inversely

x = x' * cos(theta) - y' * sin(theta)

y = x' * sin(theta) + y' * cos(theta)

Considering the segment P1-P2 direction (45° in terms of -x), we could take theta=45°. Taking the second equations of rotation into circle's equation in x-y system : x^2+y^2=1 and after simple operations we get the 'same' equation in x'-y' system : x'^2+y'^2=1.

Segment endpoints become in x'-y' system using the first equations of rotation => P1(-sqrt(2)/2, sqrt(2)), P2(-sqrt(2)/2, 0).

Assuming the intersection as P. We have in x'-y' Px = -sqrt(2)/2. Using the new equation of circle, we get Py = +sqrt(2)/2. Converting P into original x-y system, we get finally P(-1,0).

To implement this numerically, we could firstly have a look at segment's direction : horizontal, vertical or not. If it belongs to the two first cases, it's simple like I said. If the last case, apply the algorithms above.

To juge if there is intersection, we could compare the solution with the endpoints coordinates, to see whether there is one root between them.

I believe this method could be also applied to other curves as long as we have its equation. The only weakness is that we should solve the equation in x'-y' system for the other coordinate, which might be difficult.

When I know the string is going to be reasonably short then I use the following one liner... (remember to escape backslashes)

// if str is C:\windows\file system\path\picture name.jpg
alert( str.split('\\').pop() );

alert pops up with picture name.jpg

$(document.body) is using the global reference document to get a reference to the body, whereas $('body') is a selector in which jQuery will get the reference to the <body> element on the document.

No major difference that I can see, not any noticeable performance gain from one to the other.

Personally I think Thread.Sleep is a poor implementation. It locks the UI etc. I personally like timer implementations since it waits then fires.

Usage: DelayFactory.DelayAction(500, new Action(() => { this.RunAction(); }));

//Note Forms.Timer and Timer() have similar implementations. 

public static void DelayAction(int millisecond, Action action)
{
    var timer = new DispatcherTimer();
    timer.Tick += delegate

    {
        action.Invoke();
        timer.Stop();
    };

    timer.Interval = TimeSpan.FromMilliseconds(millisecond);
    timer.Start();
}

You are looking for --build-arg and the ARG instruction. These are new as of Docker 1.9. Check out https://docs.docker.com/engine/reference/builder/#arg. This will allow you to add ARG arg to the Dockerfile and then build with docker build --build-arg arg=2.3 ..

1G=G. That should indent all the lines in the file. 1G takes you the first line, = will start the auto-indent and the final G will take you the last line in the file.

try {

        BitmapDrawable drawable = (BitmapDrawable) photo.getDrawable();
        Bitmap bitmap = drawable.getBitmap();

        photo.setImageBitmap(bitmap);

Simply pass your data frame into the following function:

data_types <- function(frame) {
  res <- lapply(frame, class)
  res_frame <- data.frame(unlist(res))
  barplot(table(res_frame), main="Data Types", col="steelblue", ylab="Number of Features")
}

to produce a plot of all data types in your data frame. For the iris dataset we get the following:

data_types(iris)

I read this question looking for an answer, and didn't like any of them.

So I wrote a quick and dirty solution. Just put this somewhere on your sys.path, and it'll add any directory under folder (from the current working directory), or under abspath:

#using.py

import sys, os.path

def all_from(folder='', abspath=None):
    """add all dirs under `folder` to sys.path if any .py files are found.
    Use an abspath if you'd rather do it that way.

    Uses the current working directory as the location of using.py. 
    Keep in mind that os.walk goes *all the way* down the directory tree.
    With that, try not to use this on something too close to '/'

    """
    add = set(sys.path)
    if abspath is None:
        cwd = os.path.abspath(os.path.curdir)
        abspath = os.path.join(cwd, folder)
    for root, dirs, files in os.walk(abspath):
        for f in files:
            if f[-3:] in '.py':
                add.add(root)
                break
    for i in add: sys.path.append(i)

>>> import using, sys, pprint
>>> using.all_from('py') #if in ~, /home/user/py/
>>> pprint.pprint(sys.path)
[
#that was easy
]

And I like it because I can have a folder for some random tools and not have them be a part of packages or anything, and still get access to some (or all) of them in a couple lines of code.

You could use jquery's $.extend like this:

let a = { "one" : 1, "two" : 2 },_x000D_
    b = { "three" : 3 },_x000D_
    c = { "four" : 4, "five" : 5 };_x000D_

let d = $.extend({}, a, b, c)_x000D_
_x000D_
console.log(d)

I wanted a function that would join tables without requiring you to define the columns using an anonymous type selector, but had a hard time finding any. I ended up having to make my own. Hopefully this will help anyone in the future who searches for this:

private DataTable JoinDataTables(DataTable t1, DataTable t2, params Func<DataRow, DataRow, bool>[] joinOn)
{
    DataTable result = new DataTable();
    foreach (DataColumn col in t1.Columns)
    {
        if (result.Columns[col.ColumnName] == null)
            result.Columns.Add(col.ColumnName, col.DataType);
    }
    foreach (DataColumn col in t2.Columns)
    {
        if (result.Columns[col.ColumnName] == null)
            result.Columns.Add(col.ColumnName, col.DataType);
    }
    foreach (DataRow row1 in t1.Rows)
    {
        var joinRows = t2.AsEnumerable().Where(row2 =>
            {
                foreach (var parameter in joinOn)
                {
                    if (!parameter(row1, row2)) return false;
                }
                return true;
            });
        foreach (DataRow fromRow in joinRows)
        {
            DataRow insertRow = result.NewRow();
            foreach (DataColumn col1 in t1.Columns)
            {
                insertRow[col1.ColumnName] = row1[col1.ColumnName];
            }
            foreach (DataColumn col2 in t2.Columns)
            {
                insertRow[col2.ColumnName] = fromRow[col2.ColumnName];
            }
            result.Rows.Add(insertRow);
        }
    }
    return result;
}

An example of how you might use this:

var test = JoinDataTables(transactionInfo, transactionItems,
               (row1, row2) =>
               row1.Field<int>("TransactionID") == row2.Field<int>("TransactionID"));

One caveat: This is certainly not optimized, so be mindful when getting to row counts above 20k. If you know that one table will be larger than the other, try to put the smaller one first and the larger one second.

Small tweak to Luke's answer,

 function reloadJs(src) {
    src = $('script[src$="' + src + '"]').attr("src");
    $('script[src$="' + src + '"]').remove();
    $('<script/>').attr('src', src).appendTo('head');
}

and call it like,

reloadJs("myFile.js");

This will not have any path related issues.

I am using :: Spring Boot :: (v2.0.4.RELEASE) with Spring Framework 5

Spring Boot 2.0 requires Java 8 as a minimum version. Many existing APIs have been updated to take advantage of Java 8 features such as: default methods on interfaces, functional callbacks, and new APIs such as javax.time.

By default, Spring Boot serves static content from a directory called /static (or /public or /resources or /META-INF/resources) in the classpath or from the root of the ServletContext. It uses the ResourceHttpRequestHandler from Spring MVC so that you can modify that behavior by adding your own WebMvcConfigurer and overriding the addResourceHandlers method.

By default, resources are mapped on /** and located on /static directory. But you can customize the static loactions programmatically inside our web context configuration class.

@Configuration @EnableWebMvc
public class Static_ResourceHandler implements WebMvcConfigurer {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        // When overriding default behavior, you need to add default(/) as well as added static paths(/webapp).

        // src/main/resources/static/...
        registry
            //.addResourceHandler("/**") // « /css/myStatic.css
            .addResourceHandler("/static/**") // « /static/css/myStatic.css
            .addResourceLocations("classpath:/static/") // Default Static Loaction

In Spring every request will go through the DispatcherServlet. To avoid Static file request through DispatcherServlet(Front contoller) we configure MVC Static content.

As @STEEL said static resources should not go through Controller. Thymleaf is a ViewResolver which takes the view name form controller and adds prefix and suffix to View Layer.

Here is another way to implement SilentGhost's original suggestion:

def dict2obj(d):
  if isinstance(d, dict):
    n = {}
    for item in d:
      if isinstance(d[item], dict):
        n[item] = dict2obj(d[item])
      elif isinstance(d[item], (list, tuple)):
        n[item] = [dict2obj(elem) for elem in d[item]]
      else:
        n[item] = d[item]
    return type('obj_from_dict', (object,), n)
  else:
    return d

As you can see in the following example, json.loads (and json.load) does not decode multiple json object.

>>> json.loads('{}')
{}
>>> json.loads('{}{}') # == json.loads(json.dumps({}) + json.dumps({}))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python27\lib\json\__init__.py", line 338, in loads
    return _default_decoder.decode(s)
  File "C:\Python27\lib\json\decoder.py", line 368, in decode
    raise ValueError(errmsg("Extra data", s, end, len(s)))
ValueError: Extra data: line 1 column 3 - line 1 column 5 (char 2 - 4)

If you want to dump multiple dictionaries, wrap them in a list, dump the list (instead of dumping dictionaries multiple times)

>>> dict1 = {}
>>> dict2 = {}
>>> json.dumps([dict1, dict2])
'[{}, {}]'
>>> json.loads(json.dumps([dict1, dict2]))
[{}, {}]

@{
   List<SelectListItem> listItems= new List<SelectListItem>();
   listItems.Add(new SelectListItem
        {
          Text = "Exemplo1",
          Value = "Exemplo1"
        });
   listItems.Add(new SelectListItem
        {
            Text = "Exemplo2",
            Value = "Exemplo2",
            Selected = true
        });
   listItems.Add(new SelectListItem
        {
            Text = "Exemplo3",
            Value = "Exemplo3"
        });
}

I ran into a similar problem while creating a library to handle authentication. I want the app owner using my library to be able to register a callback with the library for checking authorization against LDAP groups the authenticated person is in. The configuration is getting passed in as a config.py file that gets imported and contains a dict with all the config parameters.

I got this to work:

>>> class MyClass(object):
...     def target_func(self):
...         print "made it!"
...    
...     def __init__(self,config):
...         self.config = config
...         self.config['funcname'] = getattr(self,self.config['funcname'])
...         self.config['funcname']()
... 
>>> instance = MyClass({'funcname':'target_func'})
made it!

Is there a pythonic-er way to do this?

Use only:

divID = "question-" + parseInt(i) + 1;

When "n" comes from html input field or is declared as string, you need to use explicit conversion.

var n = "1"; //type is string
var frstCol = 5;
lstCol = frstCol + parseInt(n);

If "n" is integer, don't need conversion.

n = 1; //type is int
var frstCol = 5, lstCol = frstCol + n;

Same issue on a Galaxy Tab and on a Xperia S, after uninstall and install again it seems that disappear.

The code that suddenly appear to raise this problem is this:

public void unlockMainActivity() {
    SharedPreferences prefs = getSharedPreferences("CALCULATOR_PREFS", 0);
    boolean hasCode = prefs.getBoolean("HAS_CODE", false);
    Context context = this.getApplicationContext();
    Intent intent = null;

    if (!hasCode) {
        intent = new Intent(context, WellcomeActivity.class);
    } else {
        intent = new Intent(context, CalculatingActivity.class);
    }
    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    (context).startActivity(intent);
}

From command line to view react version, npm view react version

An alternative is to call the pip module by using python2.7, as below:

python2.7 -m pip <commands>

For example, you could run python2.7 -m pip install <package> to install your favorite python modules. Here is a reference: https://stackoverflow.com/a/50017310/4256346.

In case the pip module has not yet been installed for this version of python, you can run the following:

python2.7 -m ensurepip

Running this command will "bootstrap the pip installer". Note that running this may require administrative privileges (i.e. sudo). Here is a reference: https://docs.python.org/2.7/library/ensurepip.html and another reference https://stackoverflow.com/a/46631019/4256346.

If you want to create a simple hyperlink instead of the pin it button,

Change this:

http://pinterest.com/pin/create/button/?url=

To this:

http://pinterest.com/pin/create/link/?url=

So, a complete URL might simply look like this:

<a href="//pinterest.com/pin/create/link/?url=http%3A%2F%2Fwww.flickr.com%2Fphotos%2Fkentbrew%2F6851755809%2F&media=http%3A%2F%2Ffarm8.staticflickr.com%2F7027%2F6851755809_df5b2051c9_z.jpg&description=Next%20stop%3A%20Pinterest">Pin it</a>

You can do like this.

<input type="button" value="mybutton1" onclick="dosomething(this)">

function dosomething(element){
    alert("value is "+element.value); //you can print any value like id,class,value,innerHTML etc.
};

In my case, where the timezones are not available on the server, this works great:

SELECT CONVERT_TZ(`date_field`,'+00:00',@@global.time_zone) FROM `table`

Note: global.time_zone uses the server timezone. You have to make sure, that it has the desired timezone!

The recommended version by Günter Zöchbauer works fine, but I have an addition to make. In my case I had an unstyled html-element and I did not know how to style it. Therefore I designed a pipe to add styling to it.

import { Pipe, PipeTransform } from '@angular/core';
import { DomSanitizer, SafeHtml } from '@angular/platform-browser';


@Pipe({
    name: 'StyleClass'
})
export class StyleClassPipe implements PipeTransform {

    constructor(private sanitizer: DomSanitizer) { }
    transform(html: any, styleSelector: any, styleValue: any): SafeHtml {
        const style = ` style = "${styleSelector}: ${styleValue};"`;
        const indexPosition = html.indexOf('>');
        const newHtml = [html.slice(0, indexPosition), style, html.slice(indexPosition)].join('');
        return this.sanitizer.bypassSecurityTrustHtml(newHtml);
    }

}

Then you can add style to any html-element like this:

<span [innerhtml]="Variable | StyleClass: 'margin': '0'"> </span>

With:

Variable = '<p> Test </p>'

After struggling a lot I finally solved the problem.

If you are prompted to download a .php file instead of executing it, then here is the perfect solution: I assume that you have installed PHP5 already and still getting this error.

$ sudo su
$ a2enmod php5

This is it.

But If you are still getting the error :

Config file php5.conf not properly enabled: /etc/apache2/mods-enabled/php5.conf is a real file, not touching it

then do the following:

Turns out files shouldn't be stored in mods-enabled, but should rather be stored in mods-available. A symlink should then be created in mods-enabled pointing to the file stored in mods-available.

First remove the original:

$ mv /etc/apache2/mods-enabled/php5.conf /etc/apache2/mods-available/

Then create the symbolic link:

$ ln -s /etc/apache2/mods-available/php5.conf /etc/apache2/mods-enabled/php5.conf

I hope your problem is solved.

Here's a working TypeScript example for those who use TS and want to debounce async functions.

function debounce<T extends (...args: any[]) => any>(time: number, func: T): (...funcArgs: Parameters<T>) => Promise<ReturnType<T>> {
     let timeout: Timeout;

     return (...args: Parameters<T>): Promise<ReturnType<T>> => new Promise((resolve) => {
         clearTimeout(timeout);
         timeout = setTimeout(() => {
             resolve(func(...args));
         }, time)
     });
 }

Another way is shown in this CodeProject article:

http://www.codeproject.com/KB/IP/tswindowclipper.aspx

The basic idea is to create a virutal channel that sends the windows position of the app(s) you want to show, then only render that part of the window on the client.

Consider normalizing to E.164 format. For full international support, you'd need a VARCHAR of 15 digits.

See Twilio's recommendation for more information on localization of phone numbers.

This worked for me as-
HTML-

    <div style="background-color: #535; width: 100%; height: 80px;">
        <div class="center">
            Test <br>
            kumar adnioas<br>
            sanjay<br>
            1990
        </div>
    </div> 

CSS-

.center {
    position: relative;
    left: 50%;
    top: 50%;
    height: 82%;
    transform: translate(-50%, -50%);
    transform: -webkit-translate(-50%, -50%);
    transform: -ms-translate(-50%, -50%);
   }  

Hope will help you too.

If you're looking for a way to normalize a date into MySQL format, use the following

$phpdate = strtotime( $mysqldate );
$mysqldate = date( 'Y-m-d H:i:s', $phpdate );

The line $phpdate = strtotime( $mysqldate ) accepts a string and performs a series of heuristics to turn that string into a unix timestamp.

The line $mysqldate = date( 'Y-m-d H:i:s', $phpdate ) uses that timestamp and PHP's date function to turn that timestamp back into MySQL's standard date format.

(Editor Note: This answer is here because of an original question with confusing wording, and the general Google usefulness this answer provided even if it didnt' directly answer the question that now exists)

I tried a number of these suggestions after realizing that an implementation I had written of this probably close to 10 years ago actually didn't work completely (nasty production bug in an long-forgotten system, isn't that always the way?!)... what I noticed is that the ones I tried (I didn't try them all) had the same problem as mine, that is, they wouldn't replace EVERY occurrence, only the first, at least for my test case of getting "test....txt" down to "test.txt" by replacing ".." with "."... maybe I missed so regex situation? But I digress...

So, I rewrote my implementation as follows. It's pretty darned simple, although I suspect not the fastest but I also don't think the difference will matter with modern JS engines, unless you're doing this inside a tight loop of course, but that's always the case for anything...

function replaceSubstring(inSource, inToReplace, inReplaceWith) {

  var outString = inSource;
  while (true) {
    var idx = outString.indexOf(inToReplace);
    if (idx == -1) {
      break;
    }
    outString = outString.substring(0, idx) + inReplaceWith +
      outString.substring(idx + inToReplace.length);
  }
  return outString;

}

Hope that helps someone!

The pythonic way of doing this is using subprocess.Popen

subprocess.Popen takes a list where the first element is the command to be run followed by any command line arguments.

As an example:

import subprocess

args = ['echo', 'Hello!']
subprocess.Popen(args) // same as running `echo Hello!` on cmd line

args2 = ['echo', '-v', '"Hello Again"']
subprocess.Popen(args2) // same as running 'echo -v "Hello Again!"` on cmd line

In Java, 2D arrays are really arrays of arrays with possibly different lengths (there are no guarantees that in 2D arrays that the 2nd dimension arrays all be the same length)

You can get the length of any 2nd dimension array as z[n].length where 0 <= n < z.length.

If you're treating your 2D array as a matrix, you can simply get z.length and z[0].length, but note that you might be making an assumption that for each array in the 2nd dimension that the length is the same (for some programs this might be a reasonable assumption).

brew should not require you to use sudo even when running npm with -g. This might actually create more problems down the road.

Typically, brew or port let you update you path so it doesn't risk messing up your .zshrc, .bashrc, .cshrc, or whatever flavor of shell you use.

You define the class gameObject in both your .cpp file and your .h file.
That is creating a redefinition error.

You should define the class, ONCE, in ONE place. (convention says the definition is in the .h, and all the implementation is in the .cpp)

Please help us understand better, what part of the error message did you have trouble with?

The first part of the error says the class has been redefined in gameObject.cpp
The second part of the error says the previous definition is in gameObject.h.

How much clearer could the message be?

You can get the HTML of the website with driver.getPageSource(). If the html does not change in a given interval of time this means that the page is done loading. One or two seconds should be enough. If you want to speed things up you can just compare the lenght of the two htmls. If their lenght is equal the htmls should be equal and that means the page is fully loaded. The JavaScript solution did not work for me.

Is there any equivalent for the truststore? How can I view the trusted certificates?

Yes there is.The exact same command since keystore and truststore differ only in what they store i.e. private key or signed public key (certificate)

No other difference

In Entity Framework 6.1+ you can use this attribute on your model:

[Index(IsUnique=true)]

You can find it in this namespace:

using System.ComponentModel.DataAnnotations.Schema;

If your model field is a string, make sure it is not set to nvarchar(MAX) in SQL Server or you will see this error with Entity Framework Code First:

Column 'x' in table 'dbo.y' is of a type that is invalid for use as a key column in an index.

The reason is because of this:

SQL Server retains the 900-byte limit for the maximum total size of all index key columns."

(from: http://msdn.microsoft.com/en-us/library/ms191241.aspx )

You can solve this by setting a maximum string length on your model:

[StringLength(450)]

Your model will look like this now in EF CF 6.1+:

public class User
{
   public int UserId{get;set;}
   [StringLength(450)]
   [Index(IsUnique=true)]
   public string UserName{get;set;}
}

Update:

if you use Fluent:

  public class UserMap : EntityTypeConfiguration<User>
  {
    public UserMap()
    {
      // ....
      Property(x => x.Name).IsRequired().HasMaxLength(450).HasColumnAnnotation("Index", new IndexAnnotation(new[] { new IndexAttribute("Index") { IsUnique = true } }));
    }
  }

and use in your modelBuilder:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
  // ...
  modelBuilder.Configurations.Add(new UserMap());
  // ...
}

Update 2

Update 3

try bind(this) so your code looks like below --

 <a className="upvotes" onClick={this.upvote.bind(this)}>upvote</a>

or if you are writing in es6 react component in constructor you could do this

constructor(props){
   super(props);
   this.upvote = this.upvote.bind(this);
}

upvote(e){   // function upvote
   e.preventDefault();
   return false

}

Ran into this issue with Parallels and VS 2013. Command + Insert also fixed it in my setup, in addition to the accepted answer. On my Windows USB keyboard Command == WindowsKey.

There's no built in function, but you can use this to get the sum,

Array.prototype.sum = function() {
    return this.reduce(function(a,b){return a+b;});
};

then divide by the arrays length, e.g.:

var arr = [1,2,3,4,5]
console.log(arr.sum() / arr.length)

mysql> SET PASSWORD for 'root'@'localhost' = password('yournewpassword');

Check this out... https://hsnyc.co/how-to-set-the-mysql-root-password-in-localhost-using-wamp/

From the documentation:

str.find(sub[, start[, end]])

Return the lowest index in the string where substring sub is found within the slice s[start:end]. Optional arguments start and end are interpreted as in slice notation. Return -1 if sub is not found.

So, some examples:

>>> my_str = 'abcdefioshgoihgs sijsiojs '
>>> my_str.find('a')
0
>>> my_str.find('g')
10
>>> my_str.find('s', 11)
15
>>> my_str.find('s', 15)
15
>>> my_str.find('s', 16)
17
>>> my_str.find('s', 11, 14)
-1

Yes. You were missing a '{' under the public class line. And then one at the end of your code to close it.

To fully overload it you also need to implement the __setitem__and __delitem__ methods.

edit

I almost forgot... if you want to completely emulate a list, you also need __getslice__, __setslice__ and __delslice__.

There are all documented in http://docs.python.org/reference/datamodel.html

How are you setting up the SqlParameter? You should set the SqlDbType property to SqlDbType.DateTime and then pass the DateTime directly to the parameter (do NOT convert to a string, you are asking for a bunch of problems then).

You should be able to get the value into the DB. If not, here is a very simple example of how to do it:

static void Main(string[] args)
{
    // Create the connection.
    using (SqlConnection connection = new SqlConnection(@"Data Source=..."))
    {
        // Open the connection.
        connection.Open();

        // Create the command.
        using (SqlCommand command = new SqlCommand("xsp_Test", connection))
        {
            // Set the command type.
            command.CommandType = System.Data.CommandType.StoredProcedure;

            // Add the parameter.
            SqlParameter parameter = command.Parameters.Add("@dt",
                System.Data.SqlDbType.DateTime);

            // Set the value.
            parameter.Value = DateTime.Now;

            // Make the call.
            command.ExecuteNonQuery();
        }
    }
}

I think part of the issue here is that you are worried that the fact that the time is in UTC is not being conveyed to SQL Server. To that end, you shouldn't, because SQL Server doesn't know that a particular time is in a particular locale/time zone.

If you want to store the UTC value, then convert it to UTC before passing it to SQL Server (unless your server has the same time zone as the client code generating the DateTime, and even then, that's a risk, IMO). SQL Server will store this value and when you get it back, if you want to display it in local time, you have to do it yourself (which the DateTime struct will easily do).

All that being said, if you perform the conversion and then pass the converted UTC date (the date that is obtained by calling the ToUniversalTime method, not by converting to a string) to the stored procedure.

And when you get the value back, call the ToLocalTime method to get the time in the local time zone.

by default you would need to use the postgres user:

sudo -u postgres psql postgres

when search field is timestamp and you want find records from 0 hours yesterday and 0 hour today use construction

MY_DATE_TIME_FIELD between makedate(year(now()), date_format(now(),'%j')-1) and makedate(year(now()), date_format(now(),'%j'))  

instead

 now() - interval 1 day

Require critical parts, like authorization and include all others.

Multiple includes are just very bad design and must be avoided at all. So, *_once doesn't really matter.

If you are using a framework like Ruby on Rails or Spring MVC you may need to use divs with square braces or other chars, that are not allowed you can use document.getElementById and this solution still works if you have multiple inputs with the same type.

var div = document.getElementById(divID);
$(div).find('input:text, input:password, input:file, select, textarea')
        .each(function() {
            $(this).val('');
        });
$(div).find('input:radio, input:checkbox').each(function() {
    $(this).removeAttr('checked');
    $(this).removeAttr('selected');
});

This examples shows how to clear the inputs, for you example you'll need to change it.

Here is my code. It'll open given url in default browser (cross platform solution).

import java.awt.Desktop;
import java.io.IOException;
import java.net.URI;
import java.net.URISyntaxException;

public class Browser {
    public static void main(String[] args) {
        String url = "http://www.google.com";

        if(Desktop.isDesktopSupported()){
            Desktop desktop = Desktop.getDesktop();
            try {
                desktop.browse(new URI(url));
            } catch (IOException | URISyntaxException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }else{
            Runtime runtime = Runtime.getRuntime();
            try {
                runtime.exec("xdg-open " + url);
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    }
}

Of the solutions you mentioned, none of them appear to give you direct access to the MapKit framework introduced in OS 3.0.

As the Google Maps HTML widgets aren't nearly as good as MapKit (see Google Latitude for an example), you are probably best off developing a native Cocoa touch application, or choosing a solution you can extend to add MapKit integration. PhoneGap is extensible in this manner (it's open-source so it is by default), and some of the other solutions might be as well.

edit: Titanium now has support for MapKit

Use the PowerConsole project on Github at https://github.com/bigabdoul/PowerConsole or the equivalent NuGet package at https://www.nuget.org/packages/PowerConsole. It elegantly handles timers in a reusable fashion. Take a look at this sample code:

using PowerConsole;

namespace PowerConsoleTest
{
    class Program
    {
        static readonly SmartConsole MyConsole = SmartConsole.Default;

        static void Main()
        {
            RunTimers();
        }

        public static void RunTimers()
        {
            // CAUTION: SmartConsole is not thread safe!
            // Spawn multiple timers carefully when accessing
            // simultaneously members of the SmartConsole class.

            MyConsole.WriteInfo("\nWelcome to the Timers demo!\n")

            // SetTimeout is called only once after the provided delay and
            // is automatically removed by the TimerManager class
            .SetTimeout(e =>
            {
                // this action is called back after 5.5 seconds; the name
                // of the timer is useful should we want to clear it
                // before this action gets executed
                e.Console.Write("\n").WriteError("Time out occured after 5.5 seconds! " +
                    "Timer has been automatically disposed.\n");

                // the next statement will make the current instance of 
                // SmartConsole throw an exception on the next prompt attempt
                // e.Console.CancelRequested = true;

                // use 5500 or any other value not multiple of 1000 to 
                // reduce write collision risk with the next timer
            }, millisecondsDelay: 5500, name: "SampleTimeout")

            .SetInterval(e =>
            {
                if (e.Ticks == 1)
                {
                    e.Console.WriteLine();
                }

                e.Console.Write($"\rFirst timer tick: ", System.ConsoleColor.White)
                .WriteInfo(e.TicksToSecondsElapsed());

                if (e.Ticks > 4)
                {
                    // we could remove the previous timeout:
                    // e.Console.ClearTimeout("SampleTimeout");
                }

            }, millisecondsInterval: 1000, "EverySecond")

            // we can add as many timers as we want (or the computer's resources permit)
            .SetInterval(e =>
            {
                if (e.Ticks == 1 || e.Ticks == 3) // 1.5 or 4.5 seconds to avoid write collision
                {
                    e.Console.WriteSuccess("\nSecond timer is active...\n");
                }
                else if (e.Ticks == 5)
                {
                    e.Console.WriteWarning("\nSecond timer is disposing...\n");

                    // doesn't dispose the timer
                    // e.Timer.Stop();

                    // clean up if we no longer need it
                    e.DisposeTimer();
                }
                else
                {
                    System.Diagnostics.Trace.WriteLine($"Second timer tick: {e.Ticks}");
                }
            }, 1500)
            .Prompt("\nPress Enter to stop the timers: ")
            
            // makes sure that any remaining timer is disposed off
            .ClearTimers()

            .WriteSuccess("Timers cleared!\n");
        }
    }
}

The to_char() function is there to format numbers:

select to_char(column_1, 'fm000') as column_2
from some_table;

The fm prefix ("fill mode") avoids leading spaces in the resulting varchar. The 000 simply defines the number of digits you want to have.

However, for the timeout part I have read about people running into problems with this. I would check out PyDNS or this solution for more advanced treatment.

Thank you for the answer above, I think the scope (of answers) is completed but I would like to add a "react way" for whoever using react.

Create a file called importData.js:

import React, {Component} from 'react';
import XLSX from 'xlsx';
export default class ImportData extends Component{
    constructor(props){
        super(props);
        this.state={
            excelData:{}
        }
    }
    excelToJson(reader){
        var fileData = reader.result;
        var wb = XLSX.read(fileData, {type : 'binary'});
        var data = {};
        wb.SheetNames.forEach(function(sheetName){
             var rowObj =XLSX.utils.sheet_to_row_object_array(wb.Sheets[sheetName]);
             var rowString = JSON.stringify(rowObj);
             data[sheetName] = rowString;
        });
        this.setState({excelData: data});
    }
    loadFileXLSX(event){
        var input = event.target;
        var reader = new FileReader();
        reader.onload = this.excelToJson.bind(this,reader);
        reader.readAsBinaryString(input.files[0]);
    }
    render(){
        return (
            <input type="file" onChange={this.loadFileXLSX.bind(this)}/>
        );
    }
}

Then you can use the component in the render method like:

import ImportData from './importData.js';
import React, {Component} from 'react';
class ParentComponent extends Component{
    render(){
        return (<ImportData/>);
    }
}

<ImportData/> would set the data to its own state, you can access Excel data in the "parent component" by following this:

First off, a disclaimer: I don't think marrying POST with URL parameters is a brilliant idea. Like others suggested, you're better off using a hidden form for passing user information.

However, a question made me curious how PHP is handling such a case. It turned out that it's possible in theory. Here's a proof:

post_url_params.html

<!DOCTYPE html>
<html>
    <head></head>
    <body>
        <form method="post" action="post_url_params.php?key1=value1">
            <input type="hidden" name="key2" value="value2">
            <input type="hidden" name="key3" value="value3">
            <input type="submit" value="click me">
        </form>
    </body>
</html>

post_url_params.php

<?php
    print_r($_POST);
    print_r($_GET);
    echo $_SERVER['REQUEST_METHOD'];
?>

Output

Array ( [key2] => value2 [key3] => value3 )
Array ( [key1] => value1 )
POST

One can clearly see that PHP stores URL parameters in the $_GET variable and form data in the $_POST variable. I suspect it's very PHP- and server-specific, though, and is definitely not a thing to rely on.

If you want to replace the entire Fragment1 with Fragment2, you need to do it inside MainActivity, by using:

Fragment2 fragment2 = new Fragment2();
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(android.R.id.content, fragment2);
fragmentTransaction.commit();

Just put this code inside a method in MainActivity, then call that method from Fragment1.

Looks like oldDTE.MyDateTime was null, so constructor tried to take it's Value - which threw.

table {
    border-collapse: collapse;
}

Below are some different ways to achieve this. Pick the one suits you

1. In fonts like 'Tahoma' and 'Times new Roman' this common password character '?' which is called 'Black circle' has a unicode value 0x25CF. Set the PasswordChar property with either the value 0x25CF or copy paste the actual character itself.

2. If you want to display the Black Circle by default then enable visual styles which should replace the default password character from '*' to '?' by default irrespective of the font.

3. Another alternative is to use 'Wingdings 2' font on the TextBox and set the password character to 0x97. This should work even if the application is not unicoded. Refer to charMap.exe to get better idea on different fonts and characters supported.

Expression: "Total Count: " + (DT_WSTR, 5)@[User::Cnt]

This is what the code would look like in a batch file(tested, works):

powershell -Command "& {set-location 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings'; set-location ZoneMap\Domains; new-item SERVERNAME; set-location SERVERNAME; new-itemproperty . -Name http -Value 2 -Type DWORD;}"

Based on the information from:

http://dmitrysotnikov.wordpress.com/2008/06/27/powershell-script-in-a-bat-file/

@media print {
  .noPrint{
    display:none;
  }
}
h1{
  color:#f6f6;
}

<h1>
print me
</h1>
<h1 class="noPrint">
no print
</h1>
<button onclick="window.print();" class="noPrint">
Print Me
</button>

I came across another elegant solution for this:

Place your printable part inside a div with an id like this:

<div id="printableArea">
      <h1>Print me</h1>
</div>

<input type="button" onclick="printDiv('printableArea')" value="print a div!" />

Now let's create a really simple javascript:

function printDiv(divName) {
     var printContents = document.getElementById(divName).innerHTML;
     var originalContents = document.body.innerHTML;

     document.body.innerHTML = printContents;

     window.print();

     document.body.innerHTML = originalContents;
}

In Rails 3, I don't know anything fancier. However, I'm not sure if you're aware, your not equal condition does not match for (user_id) NULL values. If you want that, you'll have to do something like this:

GroupUser.where("user_id != ? OR user_id IS NULL", me)

Generate a protected application for Mac or Windows from your Excel spreadsheet using OfficeProtect with either AppProtect or QuickLicense/AddLicense. There is a demonstation video called "Protect Excel Spreedsheet" at www.excelsoftware.com/videos.

If you're escaping for HTML, there are only three that I can think of that would be really necessary:

html.replace(/&/g, "&amp;").replace(/</g, "&lt;").replace(/>/g, "&gt;");

Depending on your use case, you might also need to do things like " to ". If the list got big enough, I'd just use an array:

var escaped = html;
var findReplace = [[/&/g, "&amp;"], [/</g, "&lt;"], [/>/g, "&gt;"], [/"/g, "&quot;"]]
for(var item in findReplace)
    escaped = escaped.replace(findReplace[item][0], findReplace[item][1]);

encodeURIComponent() will only escape it for URLs, not for HTML.

Well to obtain all different values in a Dataframe you can use distinct. As you can see in the documentation that method returns another DataFrame. After that you can create a UDF in order to transform each record.

For example:

val df = sc.parallelize(Array((1, 2), (3, 4), (1, 6))).toDF("age", "salary")

// I obtain all different values. If you show you must see only {1, 3}
val distinctValuesDF = df.select(df("age")).distinct

// Define your udf. In this case I defined a simple function, but they can get complicated.
val myTransformationUDF = udf(value => value / 10)

// Run that transformation "over" your DataFrame
val afterTransformationDF = distinctValuesDF.select(myTransformationUDF(col("age")))

The problem is the import of ProjectsListComponent in your ProjectsModule. You should not import that, but add it to the export array, if you want to use it outside of your ProjectsModule.

Other issues are your project routes. You should add these to an exportable variable, otherwise it's not AOT compatible. And you should -never- import the BrowserModule anywhere else but in your AppModule. Use the CommonModule to get access to the *ngIf, *ngFor...etc directives:

@NgModule({
  declarations: [
     ProjectsListComponent
  ],
  imports: [
    CommonModule,
    RouterModule.forChild(ProjectRoutes)
  ],
  exports: [
     ProjectsListComponent
  ]
})

export class ProjectsModule {}

project.routes.ts

export const ProjectRoutes: Routes = [
      { path: 'projects', component: ProjectsListComponent }
]

Just open the file with the FileMode.Truncate flag, then close it:

using (var fs = new FileStream(@"C:\path\to\file", FileMode.Truncate))
{
}

There are a few points to consider.

A \u2018 character may appear only as a fragment of representation of a unicode string in Python, e.g. if you write:

>>> text = u'‘'
>>> print repr(text)
u'\u2018'

Now if you simply want to print the unicode string prettily, just use unicode's encode method:

>>> text = u'I don\u2018t like this'
>>> print text.encode('utf-8')
I don‘t like this

To make sure that every line from any file would be read as unicode, you'd better use the codecs.open function instead of just open, which allows you to specify file's encoding:

>>> import codecs
>>> f1 = codecs.open(file1, "r", "utf-8")
>>> text = f1.read()
>>> print type(text)
<type 'unicode'>
>>> print text.encode('utf-8')
I don‘t like this

use state is not always needed you can just simply do this

let paymentList = [
    {"id":249,"txnid":"2","fname":"Rigoberto"}, {"id":249,"txnid":"33","fname":"manuel"},]

then use your data in a map loop like this in my case it was just a table and im sure many of you are looking for the same. here is how you use it.

<div className="card-body">
            <div className="table-responsive">
                <table className="table table-striped">
                    <thead>
                        <tr>
                            <th>Transaction ID</th>
                            <th>Name</th>
                        </tr>
                    </thead>
                    <tbody>
                        {
                            paymentList.map((payment, key) => (
                                <tr key={key}>
                                    <td>{payment.txnid}</td>
                                    <td>{payment.fname}</td>
                                </tr>
                            ))
                        }
                    </tbody>
                </table>
            </div>
        </div>

You can use >> to print in another file.

echo "hello" >> logfile.txt

Wrap the label and input in another div with a defined height. This may not work in IE versions lower than 8.

position:absolute; 
top:0; bottom:0; left:0; right:0;
margin:auto;

Remove the date() part

SELECT name, datum 
FROM tasks 
WHERE datum >= NOW()

and if you use a specific date, don't forget the quotes around it and use the proper format with :

SELECT name, datum 
FROM tasks 
WHERE datum >= '2014-05-18 15:00:00'

The time function returns the current time (as a time_t value) in seconds since some point (on Unix systems, since midnight UTC January 1, 1970), and it takes one argument, a time_t pointer in which the time is stored. Passing NULL as the argument causes time to return the time as a normal return value but not store it anywhere else.

private EditText edt_firstName;
private String firstName;

edt_firstName = findViewById(R.id.edt_firstName);

private void validateData() {
 firstName = edt_firstName.getText().toString().trim();
 if (!firstName.isEmpty(){
//here api call for ....
}else{
if (firstName.isEmpty()) {
                edt_firstName.setError("Please Enter First Name");
                edt_firstName.requestFocus();
            } 
}
}

To expand on Ryan's answer, when you are declaring variables (using Dim) you can cheat a little bit by using the predictive text feature in the VBE, as in the image below.

If it shows up in that list, then you can assign an object of that type to a variable. So not just a Worksheet, as Ryan pointed out, but also a Chart, Range, Workbook, Series and on and on.

You set that variable equal to the object you want to manipulate and then you can call methods, pass it to functions, etc, just like Ryan pointed out for this example. You might run into a couple snags when it comes to collections vs objects (Chart or Charts, Range or Ranges, etc) but with trial and error you'll get it for sure.

You can't rename default package since it actually doesn't even exist. All files in default package are actually in src folder.

src--
    |
    MyClass1.java <==== These files are in default package
    MyClass2.java
    |
    org
      |
      mypackage
              |
              MyClass3.java <=== class in org.mypackage package

Just create new package and move your classes within.

DLLs (dynamic link libraries) and SLs (shared libraries, equivalent under UNIX) are just libraries of executable code which can be dynamically linked into an executable at load time.

Static libraries are inserted into an executable at compile time and are fixed from that point. They increase the size of the executable and cannot be shared.

Dynamic libraries have the following advantages:

1/ They are loaded at run time rather than compile time so they can be updated independently of the executable (all those fancy windows and dialog boxes you see in Windows come from DLLs so the look-and-feel of your application can change without you having to rewrite it).

2/ Because they're independent, the code can be shared across multiple executables - this saves memory since, if you're running 100 apps with a single DLL, there may only be one copy of the DLL in memory.

Their main disadvantage is advantage #1 - having DLLs change independent your application may cause your application to stop working or start behaving in a bizarre manner. DLL versioning tend not to be managed very well under Windows and this leads to the quaintly-named "DLL Hell".

In order to capture deadlock graphs without using a trace (you don't need profiler necessarily), you can enable trace flag 1222. This will write deadlock information to the error log. However, the error log is textual, so you won't get nice deadlock graph pictures - you'll have to read the text of the deadlocks to figure it out.

I would set this as a startup trace flag (in which case you'll need to restart the service). However, you can run it only for the current running instance of the service (which won't require a restart, but which won't resume upon the next restart) using the following global trace flag command:

DBCC TRACEON(1222, -1);

A quick search yielded this tutorial:

http://www.mssqltips.com/sqlservertip/2130/finding-sql-server-deadlocks-using-trace-flag-1222/

Also note that if your system experiences a lot of deadlocks, this can really hammer your error log, and can become quite a lot of noise, drowning out other, important errors.

Have you considered third party monitoring tools? SQL Sentry Performance Advisor, for example, has a much nicer deadlock graph, showing you object / index names as well as the order in which the locks were taken. As a bonus, these are captured for you automatically on monitored servers without having to configure trace flags, run your own traces, etc.:

Disclaimer: I work for SQL Sentry.

For python, you need to use

Class pg8000.types.Bytea (str) Bytea is a str-derived class that is mapped to a PostgreSQL byte array.

or

Pg8000.Binary (value) Construct an object holding binary data.
